Abstract
A container packaging system for containers applies an apertured plastics film carrier stock to substantially identical containers such as beverage cans having annular chimes, cylindrical side walls, and frusto-conical walls between the chimes and the side walls. The carrier stock has shaped apertures to securely retain drinks cans, food cans, bottles and similar containers, as a multi-pack unit. The carrier stock is rolled onto suitably juxtaposed containers engaging a tabbed aperture edge portion progressively from above to below the upper edge of the respective containers to be multi-packed and assumes a waveform 3D conformation to unitise the containers. The rolling method contrasts prior stretch application methods and enables cheaper and thinner carrier stock to be used.
Description
Invention field
The present invention relates to method and system for carried in containers thing (container carrier) being applied to container and for container packaging system and utilize packaging system to carry out packing container.The invention still further relates to flexible carrier stock (flexible carrier stock), it such as has the beverage can of annular groove, cylindrical side wall and the frustoconical wall between groove and sidewall for machine application to substantially the same container and has the bottle of crest or seal bead.Particularly, the present invention relates to the machine application of the plastic film with hole to keep beverage pot, food cans, bottle and similar containers securely, and relate to the method for uniqueness film being applied to container, and the combination that the packaging of many packagings or modularity is provided obtained.
background of invention
As usual, be packaged in tank by beverage such as bubble fruit juice, cola drink, beer and analogue, these tanks are manufactured by extruded aluminium or galvinized steel usually, about about 50 μm of thickness.These tanks are sold with four packagings (2 × 2)-or six packagings (3 × 2) usually.The example in the early time packing such packaging makes the cardboard modularity of encapsulation tank.In the 1950's, first disclose plastic film container load.The form in the early time of plastic film container load makes hole modularity, these bore deformations when being applied on tank by sheet (sheet), and film forms continuous print lug area around the limit of tank thus.Film is placed on below the beaded edge of junction formation of the lid of tank around the top of tank.Although this form in the early time of load film allows tank to be hauled out-exist the counter motion of some difficulty-tanks relative to load mean that plastic flange will move the sizable power of needs with toilet-cleaning jar near crimping and further.
Fig. 1 shows the example from US 2 874 835 (ITW), which provides the load 30 of the plain film comprising plastic material, and this plain film is provided with multiple hole 32.The diameter of the tank that hole is significantly less than (> 20%) is kept by load.Fig. 1 a shows in use how to keep tank, and wherein the internal edge of the circumference of plastic eyelet engages with the lower edge at edge 46.Visible, plastics load material is stretched to be out of shape substantially-after the sizable power of application-and make the edge-perpendicular in hole in the plane of the periodically plastics load of placing tank, especially with reference to the parts 40 in Fig. 1 b.In fact, US 2 874 835 shows, needs outstanding power unexpectedly to be unclamped from maintenance equipment by tank.The disclosure of US 2 874 835 shows, polyethylene is preferred plastic material, its in press punching press to form hole.This example teaches extra hole (hole), and the end of the handle of elongation inserts by extra hole subsequently.Carrier stock-being stretched exceeds its elastic limit for these plastic films-be commonly called.That is, hole large young pathbreaker so that be drawn into and the shape of the shape complementarity of container (according to US 4 250 682 (ITW)).After being removed from load by container, in the application process for packing object, load can not be reused because of permanent tensile deformation.
Carrier stock is polyethylene normally, and has 500 μm or larger thickness in example in the early time, although for the load at application edge, and thickness normally 400 μm or larger.
Enable plastic film engage with the limit of tank needed for power be sizable and, certainly, problem when accessing each tank for container package large power together being caused customer.GB 1 200 807 (ITW) introduces slit in hole, but application power remain sizable because hole " be significantly less than the diameter of tank, load film will be assembled together with tank " and therefore still stretch exceed elastic limit of materials.
US 2 997 169 teaches by comprising the solution to this problem of tearing fin 72b; According to Fig. 2 a and Fig. 2 b, the precharge component relevant to tab portion can be torn plastics and keep film, and this edge being considered to order about than the plastic film around drawn tank is easy.The diameter of the diameter than hole of tank is large, and correspondingly, stretchable holes and make contiguous material deformation be frustoconical shape, and tank is strongly kept stoping in the taking-up of going up in the opposite direction with the side inserting them thus.
US 2 936 070 teaches also another patent, and the instruction of this patent is that it provides the grip portion not being subject to impact tank being lost by distortion and curvilinear movement for solving such plastics load.With reference to Fig. 3 a and Fig. 3 b, upwards order about elastomeric flexible grips 28 (in packaging process when plastic film is placed on many tanks), handgrip is determined by root 30, and this root 30 is partly defined as the inner edge section in hole.Fig. 3 b and Fig. 3 c shows the instruction from existing retainer with lateral plan, and wherein circular crenulation 28 is clearly visible.US 2 936 070 set forth the diameter that root diameter (RD) is less than tank particularly, and near root, still sizable tensile force is applied to plastic material in the process by material extending being frustum of a cone, and almost cylindrical configuration is shown in Fig. 3 c.Description also discloses, and " load can with sizable facility by downward punching press load and assembled together with tank simply on the tank of suitable number.Cam driven access aperture used simply by tank, deflection handgrip .... tank strongly can be firmly grasped by the handgrip below the crimping abutting against tank thus ".In fact, stamping press will be sizable.
Development in addition comprises different changes: a suggestion about article carrier thing is formed from tubes, this pipe alternately splits from side to side in the mode of the connecting bridge do not split retaining the follow-up relative edge replaced, and the continuous part of pipe relative to each other can be folded into common sides substantially for receiving the article be handled upside down thus.In order to save material, tube wall is made thin as far as possible by hope usually, meets required intensity and durability.Therefore, up to now, in the structure of this proposition, the article of the next-door neighbour in packaging are spaced only by the region that double thickness is contacting with load of the material of relative thin.Find, for many objects, such interval is not enough, because the article be close in practice such as bottle or tank can be rubbing against one another to make corresponding surface may produce cut or otherwise sustain damage.Such as, as usual, by photoetching or other means, mark or other Art Design are applied to beverage can, and if allow tank exceedingly rub together such as in transportation when make packaging stand continuous print motion or vibration time, this mark can be damaged.US 3 924 738 provides the rib device by forming longitudinal extension, provides the solution to this problem of separation spacing thus, as shown in Figure 4 between tank.
US 3 968 621 teaches and manufactures load by forming the meshwork extruded, subsequently by using roller that this meshwork is flattened the perforated film producing carrier stock, as shown in Figure 5.
US 3 317 234 teaches the packaging system utilizing upper layer stampings and lower layer stampings.As with reference to seen by Fig. 6 a and Fig. 6 b, upper layer stampings comprise the first continuous plastic layer and comprise the second layer stampings of porose card layer, and these upper layer stampings to be placed on bottle and to arrange bottle.The hole of card layer is arranged to be engaged on the corresponding metal cap of Drinking bottle, and the neighboring in hole is arranged to engage with below metal cap, keeps the upper part of bottle thus.Lower layer stampings be arranged in a similar fashion with the bottle effect with distinctive waist, the card component of second layer stampings can engage around this distinctive waist with plastic layer, this plastic layer encapsulating bottle low portion.In a similar fashion, tank is kept by substantially similar ground floor stampings and second layer stampings, its card member and the corresponding upper flange of double flange formula tank and the directed edge joint of the body of lower flange.
In phase early 1980s, exist in method film bracket being applied to tank or analogue and change.Previous form for the belt bracket of the hydrostatic column of circle provides substantially circular hole.On the contrary, the instruction being equal to or stemming from US 4 219 117 (ITW) proposes carrier stock, and it is designed to be applied by special pawl and drum machine (describing in such as US 4 250 682).These suggestions relate to such bracket, and it has the band section of integrated connection, and this band section defines tank receiving opening in longitudinal row and transverse row.Comprise substantially longitudinal outer section with section, and each outer section partly limits tank receiving opening in row outside.The hole defined in this bracket is triangle/D shape substantially, be mainly used in helping bracket mechanically to place around the edge of tank, this machine applications makes the use of mechanical gripper necessitate, and uses while this handgrip stops this equipment in any configuration except providing two row's longitudinal rows (two-ranklongitudinal rows) usually.That is, tank is attached with two tanks to be arranged in juxtaposition: the use of system is restricted and usually can not reliably operates to provide such as with the tank that the layout of 3 × 3 or 3 × 4 or 4 × 4 etc. is packed.
Illustrate in US 4 219 117 and in the carrier stock described, band section also comprises: inner segment, and it partly limits tank receiving opening; And the section of horizontal expansion, it connects inner segment, for handgrip gripping element.
In the past, tank maker introduces the tank compared with the diameter of sidewall with less groove diameter.Such tank is called as " inside constriction " tank.The tank of these inside constriction of up-to-date version further and reduce the ratio of groove diameter and sidewall diameter significantly.When by known program application bracket, the band section defining tank receiving opening promptly the frustoconical wall of tank and the lower edge of engagement groove tightly.
In the tank of the inside constriction compared with newtype, the frustoconical wall between groove and sidewall defines the coning angle that is greater than about 28 ° and defines the large coning angle to about 37 ° in some cases.When frustoconical wall defines such wide-angle relative to the axis of tank, be difficult to apply carrier stock, because the less desirable tendency on the band section defining tank receiving opening has on the lower edge that makes tank upward sliding and be shelved on groove tank.This tendency is enhanced due to above-mentioned pawl application system.
Another problem of known system is when using very large power to apply carrier stock, in use these very large power may be difficult to remove-be not only unexpected-be especially difficult to be removed by youngster, this causes the generation bubbled over, because remove by power the unnecessary upset that beverage pot causes inner bubbling liquid from load band, follow-up open tank time cause spraying or overflowing.
EP 0 461 748 (ITW) and EP 0 621 203 (ITW) proposes and provides tear open tab, that it extends up through straight the wall respectively and groove of the tank of taper, makes release simplify thus.Fin in latter patent has the Outboard Sections of the concave surface of the bar of the contiguous fin for " stress elimination ".In addition, these files all relate to the use of relatively thick (being greater than 400 μm) carrier stock, and being stretched around these carrier stock of tank in placement exceeds its elastic limit.But the carrier stock of these types is not widely adopted.
summary of the invention
The present invention attempts to overcome at least one problem relevant to prior art.Especially, specifically described the present invention attempts to provide the machine and the technique that utilize the plastics carrier stock sheet comprising film plastics to combine also packing container such as tank and bottle hereinafter, does not need very large tensile force to realize the attachment (" modularity (unitising) " of so-called container) of some containers in six packagings or similar smaller or greater packaging thus.
This purpose is by using application roll to be attainable, and this application roll is configured to will the carrier stock sheet film of appropriate bore be had to promote be accumulated on the edge together for the continuous container of modularity progressively.Application roll coordinates with upper vessel portion edge (crimping, groove or edge) locates with the inner edge section in the hole of the carrier stock sheet by comprising plastic film and brings to top edge, and is moved this marginal portion progressively under upper vessel portion edge until whole internal holes edge local is under this upper vessel portion edge.
The carrier stock sheet film of appropriate bore that has in various embodiments is the theme of patent application GB 2 475 622 A and WO 2,011 061 518 of common pending trial, and these applications are incorporated to accordingly by quoting.
Term load, carrier stock, load sheet (carrier sheet) and retention tab can use at this convertibly so that describe different aspect of the present invention, and refer to the flexible load comprising plastic film, it is adapted to pass through more specifically described method hereinafter and packs, especially, not needing to use in routine use for separation or the stretcher of packing container, not needing the tensile force of the elastic deformation limit applied exceeding plastic sheet material yet.
Particularly, it should be noted that the application roll being suitable for promoting carrier stock on the container of accumulation according to the present invention does not need to be used for making the similar effector needed for load and container stretching engagement in the pawl expanded, the handgrip (finger) separated or prior art.More properly, according to the present invention, when the porose load of process or retention tab make the container unit of multiple accumulation, the container of roller and accumulation is made side by side when roller rotates relative to the edge of container, and the inner edge section in the hole of porose load sheet is bonded under edge at first make contact place.Afterwards, the remainder that roller promotes the edge in hole with dislocation (ease) lightly on edge, the marginal portion on load sheet is pushed to progressively under edge until whole bore edges is under the edge of container.
According to a first aspect of the invention, the machine by roller, carried in containers thing being applied to container is provided.
The configuration of carrier stock, especially hole configuration make to coordinate in conjunction with the top edge of roller application process with container such as tank, and initial plane carrier stock is by the 3-d modelling be again configured as around tank.
Formed and comprise plastic film material by the carrier stock of the carried in containers thing of machine application, it has the multiple holes for being kept together by multiple container, hole is arranged and continuously at least first direction, normally machine direction extends, apply for the continuous print band as the reel (reel) from supply system such as aforementioned porose plastic film.Suitably, hole has center and peripheral, and wherein the edge of well-defining has the geometry of the multiple fins (tab) comprised in the face of center, and fin is separated by groove, and groove comprises root at out of center maximum of points place; Wherein the innermost edge of fin and root lay respectively at relative to center the first circumference and second circumferentially, the second circumference is equal to or greater than the crimping circumference of container; When the configuration in hole makes to place around container, along with the plastic film around container is pushed down and plastic film flexibly forms three-dimensional wavy form structure around container, the edge of fin engages with the described crimping of such container.
Load film preferably utilizes to be made up of the following group formed: polyolefin plastics such as polyethylene and polythene derivative such as copolymer and addition polymer or blend polymer, but can use other plastic material with similar mechanical characteristics comprising recycled plastic.Load film can be advantageously made up of thinner plastic film, such as, is made up of the plastic film of as many as about 350 μm of thickness.Can be used to some containers at least about the plastic films of 50 to 75 μm, and normally the plastic film of as many as about 100 μm will be suitable for eurypalynous container perhaps.In order to optimum performance of the present invention, carrier stock can be made up of plastic film completely, but do not get rid of the laminated product comprising described film and another kind of material, this another kind of material does not suppress flexible and applies with the roller allowing carrier stock as described herein on container.Similarly, can use not with the paper tinsel of any coating of roller application interfere, mark, mark, chromatograph or application.
Load plastics fenestra can be sized to be applicable to around the tank with cylindrical wall.Load plastics fenestra can be sized with the tank be applicable to around the groove reduced or constriction.Load plastics fenestra can be sized to be applicable to around the crimping around the neck of bottle.Therefore, make load film pore-forming to be formed for will the container engagement portion of each container of modularity or many packagings divide.Machine can accept the bracket of the single row or multiple rows perforated film comprising certain length.
After on the top that this plastic film is pushed to container, can observe, previous flat plastic membrane portions ground meet container neck or under the groove part of container, and other parts form groove so that all flat plastic film is transformed into running surface with desired use, and this running surface is extended between the container being carried out modularity by film.
Machine also comprises the conveyer system for transfer cask, and it can be usually known type; Conveyer is operable as supply for receptacles to accumulation position; And the container band of accumulation is used for the porose load of such as aforementioned carrier stock or the application of retention tab to application station.Machine uses roller porose load or retention tab to be pushed on the container of the accumulation at application station place.Roller is received from the porose load of supply system or retention tab.
For by porose plastic film the roller be pushed on the container of accumulation can have the surface configuration of improvement with porose plastic film to be pushed in the process on the container of accumulation or afterwards by a certain amount of force applications to porose plastic film.This guarantee following in can have benefit: during when the container motion of roller relative to continuously accumulation, each hole is suitably located relative to the edge of container, and the edge in hole is always pushed under the edge of cell therefor.Particularly, roller can have the such as spaced pillar of protrusion or rib, and it is positioned at joined web between the porose load of plastic film or the hole of retention tab.
Eligibly, conveyer and roller are arranged to jointly coordinate with supply system, make, when conveyer mobile containers, the edge of container to be brought to the carrier stock of porose plastic sheet, and the inner tab edge in hole can near the lower edge of the crimping of container thus.Meanwhile, under the continuous promotion motion of movable roller, the carrier stock of porose plastic film is pushed on the edge of accumulation container of conveying.Particularly, the effect promoting roller when applying porose plastic film makes the lateral edges in hole flexibly depart from around the limit of container bead at edge defining container, until the internal edge adjacent edge edge relative with first jointing edge in hole in hole.At that time, the internal edge at the described relative inner tab edge of the impetus causing hole of roller engages with below edge, porose film and tank is fixed thus.
Eligibly, before bringing to application station, container is moved to accumulation position by conveyer.Eligibly, the container of the plastic film with application is moved to cutter sweep by conveyer, and described cutter sweep is operable as and can produces suitable packaging size, can realize the separation of the container package of modularity thus.
Eligibly, provide the sheet supply axle of multiple co-operate, thus, provide without interruption to roller of sheet, to realize the seamless link of the sheet be separated to provide the actv. continuous handling of system.
According to another aspect of the present invention, provide the method utilizing machine and porose plastic film to make container such as tank modularity, the method also comprises the steps: to receive tank; Towards the internal edge of the fin in the promotion hole, lower recess edge of tank; The fin of the adjacent side in hole is displaced on the corresponding edge portions of tank lightly, until the internal edge adjacent edge edge relative with first jointing edge in hole in hole; And, the internal edge of last fin is engaged with below edge, thus porose film and tank is fixed.
The carrier stock be suitable in machine of the present invention and method is provided with the multiple holes for being kept together by multiple container, carrier stock comprises the plastic film material with multiple hole, this some holes is arranged to the series such as at least first direction, its mesopore comprises the multiple handgrip or wing members that are separated by groove, and hole has center; Wherein the innermost edge of handgrip element or tip be positioned at relative to center first circumferentially, and the bottom of groove be positioned at relative to center second circumferentially, the second circumference is equal to or greater than the circumference of container; Wherein along with groove is by downwards and outwards promote, the edge being operable ground of handgrip engages with the crimping of container; Groove is operable as and allows film be flexibly out of shape when placing and film can be made to take three-dimensional structure.Although the present invention needs at least three handgrips or fin, but find, owing to being allowed the film upward movement of adjacent grooves by the power of handgrip from groove, rough wave effect or running surface is produced, so (fin) hole of four handgrips is favourable in the packaging of product thus between contiguous container.The three-dimensional structure taked of film is similar with the monocoque of vehicle in effect; Be pushed as the intensity before contacting with container because the intensity of the bracket of the wave shape contacted with container is greater than other flexible material.
Applicant determines, and below the crimping that fin or handgrip encounter container during the groove of such as beverage can, material deflects in a downward direction.Because contact is discontinuous, this makes to produce in the material and acts on fin or handgrip and impel their to keep the three-dimensional wave contacted with container.In the corner (such as in four packagings) of sheet, otch (cut out) relatively in knock hole, because there is not downward power, the side force that the effect only acting on groove by handgrip applies, material is ordered about enters top, its from tank farthest some place contribution rough wave effect.This combination on rough wave effect and top also stops handgrip leave below groove and guarantee that container is firmly held.
Porose material can be sized to be applicable to around the such as traditional baked bean tank (such as, 307 × 512US CMI) of traditional tank with cylindrical shape wall.Porose film can be sized to be applicable to around the tank of inside constriction, and as usual (2011) produced in beverage Industry at present, in Europe, it is for one of Types Below (overall dimension is for approximate value) 330ml,
highly; 440ml,
highly; 500ml (~ 16 fluid ounce US)
highly.
The size introducing the another kind of 250ml tank of professional beverage such as so-called energy drink is also constriction and be about slightly
highly.
Owing to treating these size differences of the container of modularity when different times, machine of the present invention can be equipped with control apparatus, for change application roll to run relative to the packaging of different vessels between the relative positioning of the container being transferred and accumulating.
Porose film also can be sized to be applicable to around the bottle of ridge constriction, wherein can act on groove or the crimping of tank in a similar fashion around the crimping of the neck of bottle.
Hole can (four limits are arc) hole of similar cardinal principle square shape, and wherein fin comprises slightly outward extending arc.For the container being generally used for beverage, other how arc hole is fine, but the number of fin is less than ten.
Can comprise the band section of integrated connection for the carrier stock comprising plastic film of the present invention, this band section defines tank receiving opening in longitudinal row and transverse row.Single longitudinal row can be there is.Comprise substantially longitudinal outer section with section, and each outer section partly limits tank receiving opening in row outside.In the application, carrier stock or film can be set to volume, for being used in the method for this product of application as rolls, eligibly with usually but be not the wide multi-route forms of 6 routes uniquely.Sheet material is supplied to rolls up upper and is supplied in applied for machines with approximately continuous action, and now it is divided into the packaging size of needs again in machine, such as 4 packagings, 6 packagings etc.
Method film being rolled to the top of container utilizes the downward pressure of roller, along with container process in its lower section, with the interaction by film and container mildly flexibly shaped material to realize the three-dimensional transformation of above-mentioned promptly effect and sheet material.Therefore, roller film is pushed to will modularity accumulation container on time also there is following effect, promote the performance of film by promoting the particular configuration that will adopt.
Particularly, as the direct result of the different power acted on material, plastic film defines 3D shape after being applied to multiple container, increases the inherent strength of the product obtained thus.Increase the direct result of (form with three-dimensional) as applied film strength, the grade (grade) of membrane material and the reduction of thickness can be realized: because need less raw MAT'L, so cost can reduce.Further, engage with container to realize material because machine does not need to apply great power, the technical requirements of packaging plant can reduce, and again reduces cost.Total significant energy saving can be realized by the present invention.
Other advantage is in addition, because machine is not huge and can applies when not using large gripper/hand (as used in the industry at present-its hinder the function of the gripper/hand of positioned adjacent), 12-hole row can be placed-even can be manufactured to some packaging stream simply with side-by-side configuration.
Therefore, present invention utilizes the physical property of apertured plastic membrane material, thus, astoundingly, container such as beverage can be kept by the sheet of following thickness, this thickness is greatly reduced relative to the thickness of the sheet on the edge being placed on container of institute's widespread use so far, thus, below the edge, multiple internal edge adjacent side that the internal circumference in hole defines, internal circumference is less than the circumference of tank in a free state, due to the discontinuous circular contact around described edge under edge, sheet material is thus to provide the three dimensional form of stability and intensity to meet to container and film combination.Especially, three dimensional form provides the intensity much larger than utilizing the attainable intensity of standard film.As the direct result of the intensity that it increases, the material of selection for price and availability instead of can be selected for quality itself.
Above advantage and other advantage can realize object of the present invention.

detailed description of the preferred embodiments
Now the mode only by embodiment is described contriver current thought be used for implement best mode of the present invention.In the following description, set forth many details to understand completely of the present invention to provide.It will be obvious to those skilled in the art that the present invention can utilize the version of details to implement.
for the carrier stock of modularity container
Now with reference to the first embodiment shown in Fig. 8 a-Fig. 8 c, the present invention is described.Fig. 8 a and Fig. 8 b shows the first transparent view and second transparent view of the layout of five beer cans kept by the plastic film bracket with six container holes.
Plastic film is show in plan view in Fig. 8 c.Each hole 80a is substantially square, is operationally arranged through the cylindrical part that it receives the circle of container, and wherein four handgrips or fin 81,82,83 extend from the breach or groove with the mesh element being connected contiguous handgrip or fin with 84.Groove is in the radius of the radius being slightly greater than container, and film is designed to keep around this radius of container.The tip of handgrip or fin, that is, by the edge of adjacent tank or the part of groove, eligibly curve inwardly slightly.In fact, in order to the most closely coordinate around container, arc is corresponding to the arc of circumference with the radius corresponding to the radius of container, and it orientates edge or the groove of direct adjacent vessel as, shape considers the following fact: in view of the elasticity of utilized plastic film, and film will take wavy shape.Although it should be noted that the elastic performance that make use of film, not close to elastic limit of materials.
In use, carrier stock is provided with the many holes for being kept together by many containers, and bracket comprises thin plastic material, and this thin plastic material has the many holes arranged at least first direction.Hole comprises the multiple fin or handgrip element that are separated by groove, and hole has center.The tip of handgrip element be positioned at relative to center first circumferentially, and the bottom of groove (the decentering part farthest of groove) be positioned at relative to center second circumferentially, the second circumference is equal to or greater than the circumference of container.In use, the tip of handgrip engages with the crimping of container, and as direct result, because groove is a part for same film, therefore groove is promoted downwards and outwards.In doing so, groove promotes film to be flexibly out of shape when placing, and film can be made to take three-dimensional structure.Although the number of fin or handgrip upwards can change from three, but find, owing to being allowed the film upward movement of adjacent grooves by the power of handgrip from groove, produce rough wave effect thus, therefore in the packaging of product, four holes with handgrip (or can operate the multiple handgrip equivalents realizing identical effect) are favourable.The three-dimensional structure taked of film in many aspects in be similar to structure type in Rail car manufacture, that is, structure is monocoque, and wherein the bulk strength of finished film is greater than the bulk strength of intrinsic flexible material.
Concrete with reference to Fig. 8 c, film 80 is provided with hole 81, and hole is defined by handgrip 82-85.A hole 81 will be discussed now; Distance between the center of the handgrip that opposite face is right is approximately hole by 90% of the diameter of the container part closed around it, and the distance between relative groove corresponds to 110% of described diameter.As seen with further reference to Fig. 8 a and Fig. 8 b, handgrip 82-85 adjoins the groove of tank or the low portion at edge, and film close follow the inside neck down portions of container.Be not utilize the elasticity of material to be kept to make container, film according to the present invention takes three-dimensional geometrical structure form when as described herein by rolling and applying, and this three-dimensional geometrical structure form enables the shape of film provide the layout of relative rigidity thus.In fact, it not the new plastic film of the high-quality utilizing preferred thickness in the scope of 400-500 μm, according to applied container, object is by using thinner material and uses weight little as far as possible, and the present invention can utilize thickness about 350 μm or even less such as about 100 μm or less recycled plastic film.Realize, although be approximately two grams for the weight of the single perforated film of six packagings, in the whole world, the plastics of a few kiloton are used in the manufacture of the container utilizing film.Amount minimizing 25% of plastics or more will make the running cost of any tinning factory significantly reduce.In addition, this area (such as EP1038791) it is known that due to the view of client, make horizontal net any bending drop to minimum; Think smooth horizontal net pleasant more from aesthstic angle.
As will be understood, the existing system for connecting container is closely close to the elastic deformation limit of plastic material.In fact, at US-A-4,250, in the device shown in 682, show and engage load band and the machine assembled with the multiple article moving to it with close relation by load band.US-4,250, device in 682 has the swing roller with load tensile member, and load tensile member is used for, on the top of the article under it moved in load band joint, stretching and location, load material being remained under the groove of article.Similarly, in another instruction (EP0456357), set forth the load that load band conjugative component is used to be used in the joint assembled with article be out of shape with flexibility.
Because salvage material more may have impurity and other shortcoming, these can damage the intensity of the material stretched to elastic limit, and industry can not accept such material before, adds the financial burden in packaging industry.The present invention provide not only and uses the raw MAT'L fewer than existing solution and the solution more meeting " environmental friendliness ", and in fact can comprise salvage material for raw MAT'L of the present invention or at least have significant salvage material content.
