Abstract
For packaging foodstuffs or semi-luxury goods, the invention proposes packaging in which a protective packaging means (21) contains an inner packaging means (11) which contains the material to be packaged. The two packaging means are each produced from a strip (3, 13) by the strip being guided together to form a flexible tube (14). The inner packaging means is connected, in the region of its one end, to the outer packaging means such that, when the outer packaging means, which constitutes a protective packaging means, is torn open, the inner packaging means, rather than being destroyed, remains in the one part of the torn-open protective packaging means. The inner packaging means can preferably consist of a different material to the outer packaging means.
Description
- The invention concerns a packaging, in particular, a packaging for foodstuffs and semi-luxury goods, as well as packaged semi-luxury goods. The invention also concerns a method for packaging semi-luxury goods or foodstuffs.
- Foodstuffs and semi-luxury goods are frequently offered to users in small, individually packaged portions, where the foodstuffs involved could be, for example, chocolate bars, that are intended for immediate consumption or, for example, teabags, that still need to be treated. Individually packaged portions of coffee that are still to be brewed are also familiar. It will be evident from the examples of teabags and prepackaged portions of coffee that their packaging must remain sealed as this encloses the contents during usage.
- The invention is based on the problem of devising a packaging, in particular, a packaging for foodstuffs and semi-luxury goods, which can be handled in a simple and suitable manner.
- In order to solve that problem, the invention proposes a packaging having the features stated in claim 1. The invention also proposes a method for packaging foodstuffs and/or semi-luxury goods. Elaborations on the invention are covered by the sub-claims.
- The invention therefore proposes a packaging which accommodates an inner packaging that contains the item, for example, a foodstuff, that is to be packaged. This inner packaging is firmly joined to the protective packaging at a single location. Therefore, when the user, perhaps manually, opens the protective packaging, the inner packaging containing the packaged item will remain within the protective packaging and not fall out, which both simplifies the handling and allows the user to move and handle the inner packaging containing the packaged item by means of the protective packaging, without handling the inner packaging—which can be highly beneficial, particularly where foodstuffs are involved.
- To facilitate the opening of the protective packaging, according to an elaboration on the invention, it may be provided that the protective packaging has perforations extending along a closed line, or another weakened zone, that may be readily broken manually. Depending upon the type of material employed, this weakened zone might also be configured such that the protective packaging is merely weakened and has no perforated holes there.
- It has been proven particularly practical if the protective packaging and, if necessary, also the inner packaging, has a longitudinally extended shape, while the perforation, or other sort of weakened zone, is arranged transversely in respect to the longitudinal direction. In particular, it may be provided that the protective packaging has a grasping tab on either end. The user can then tear open the protective packaging by pulling on the grasping tabs. Once the protective package has been torn open by simply pulling on it, he/she will be able to immediately recognize whether the inner packaging is arranged within one or the other part of the protective packaging.
- Depending on the circumstances of the particular case, the protective packaging might have several inner packaging sections. In the case of its primary intended purpose, namely, being able to offer single portions in a protective packaging, in accordance with an elaboration on the invention, it may be provided that just a single inner packaging containing a single portion of the item to be packaged is arranged in a protective packaging, where it may be provided that the inner packaging and protective packaging have almost the same dimensions.
- Under an elaboration on the invention, it may be provided that the inner packaging and/or the protective packaging are manufactured in the form of tubular sections formed from a strip of material.
- In order to manufacture individual inner packaging sections and/or protective packaging sections from a strip of material that has been joined such that if forms a flexible tube, according to an elaboration on the invention, it may be provided that the flexible tube is pressed flat at separation zones running transversely to the flexible tube and the two sides of the flexible tube are joined to one another by, for example, cementing or welding them together.
- In particular, it may be provided that the flattened sections on either side of the separation zones also form the grasping tabs.
- In order to manufacture the inner packaging from a strip of material, according to the invention, it may be provided that an edge of the strip of material is folded over outward and that the opposing edge is joined or cemented to the outer layer of the folded-over zone.
- If so, it may be provided that a zone extending along the edge of the folded-over edge remains loose. This loose portion of the edge of the strip of material may be utilized to generate a joint with the inner surface of the protective packaging.
- Under an elaboration on the invention, it may be provided that, in order to form the protective packaging, an edge of the strip of material is folded over outward and the opposing edge of the strip of material is joined to the outer layer of the folded-over edge.
- As already mentioned, a user should be able to simply tear open the protective packaging and the inner packaging containing the foodstuff should then remain in one of the two parts of the separated protective packaging. To achieve this, according to an elaboration on the invention, it may be provided that the joint between the inner packaging and the protective packaging is provided in the vicinity of one end of the packaging only. No joints between the protective packaging and the inner packaging will be provided on other parts of the packaging.
- Under an elaboration on the invention, it may be provided that the strip of material utilized for manufacturing the inner packaging consists of a differing, or differently treated, material than the strip of material utilized for manufacturing the protective packaging. For example, in the aforementioned case of teabags, the inner packaging might consist of a material permeable to water and having no effect on taste, while the protective packaging consists of a hermetically sealing material.
- The invention also proposes a method for packaging foodstuffs and/or semi-luxury goods, as defined in the independent claims regarding said method.
- According to the invention, providing items to be packaged in their inner packaging and inserting their inner packaging into their protective packaging may take place consecutively on the same apparatus.
- Further features, details and benefits of the invention will be evident from the claims and the summary, the wording of both is herewith an integral part of the content of the following description of preferred embodiments of the invention by way of reference thereto, and from the drawings, which depict:
-
FIG. 1 a schematization of the packaging procedures according to the invention; -
FIG. 2 the manner in which a flexible tube is formed from a strip of material; -
FIG. 3 the manner in which the strip of material is folded over in order to generate a section of flexible tubing; -
FIG. 4 a sectioned view of the inner packaging; -
FIG. 5 a sectioned view of the protective packaging and the inner packaging contained therein; -
FIG. 6 a view of the completed packaging; -
FIG. 7 a view of the protective packaging in an opened state. - Proceeding from top to bottom in
FIG. 1 , the inner packaging is first manufactured and filled; the inner packaging is then inserted in the protective packaging. Both procedures, that is, the manufacture and filling of the inner packaging on the one hand, and the manufacture and filling of the protective packaging on the other, take place on the same apparatus and consecutively. - Arranged at the top of
FIG. 1 is a filling tube 1 that has afilling funnel 2 on its upper end. Astrip 3 of material is horizontally fed in from one side and redirected downward by a diverting mechanism 4. Thestrip 3 of material is formed into a flexible tube by a forming shoulder that is not shown. Aflat jaw 5 that may be pressed against thestrip 3 of material (cf. the arrow 6 inFIG. 1 ) and is capable of joining the two edges of the strip of material is arranged on the side of the filling tube 1 that faces away from thestrip 3 of material that is being fed in, which will form the strip into a flexible tube. The strip is drawn downward by mechanisms that are not shown. A single portion of the item to be packaged is filled into thefilling funnel 2 and then glides downward through the filling tube 1, and collects near the bottom end of the flexible tube. The flexible tube is then treated in aseparating mechanism 8 such that the flexible tube is pressed together and the adjoining layers of the flexible tube are joined to one another. Aknife 9 on the separating mechanism then cuts off the inner packaging. Theseparating mechanism 8 has a pair ofjaws 10 that may be moved toward one another until they contact one another. - By this means, in the upper half of the figure, individual inner packaging sections are filled and separated from the flexible tube formed from the
strip 3 of material. These individual,inner packaging sections 11 then fall into a second filling tube 12 in order that aflexible tube 14 will be formed from astrip 13 of material in a manner similar to that depicted in the upper half of the figure. The edges of thestrip 13 of material are joined together using awelding chuck 15. The jaws of thatwelding chuck 15 may also be moved toward one another (cf. the arrow 16) and are thus capable of joining the two edges of thestrip 13 of material to one another. - Here again, the
flexible tube 14 is drawn downward and guided through aseparating mechanism 18. Thisseparating mechanism 18 is constructed in the same manner as theseparating mechanism 8 shown in the upper half of the figure, i.e., it also incorporates aknife 19 and a pair ofjaws 20. The result is aninner packaging 11 that is accommodated in aprotective packaging 21 exiting the far end of the mechanism. While theinner packaging 11 is being manufactured from thestrip 3 of material, theprotective packaging 21 is being formed from thestrip 13 of material. - Before the
strip 13 of material is formed into theflexible tube 14 by being run over a forming shoulder, it runs through astation 22 that also has a pair ofjaws 23 that may be moved toward one another. However, here the material is notched or perforated, rather than separated. Whether it is notched or perforated will depend upon the circumstances of the individual case involved. This notched, or weakened, zone is generated at regular intervals, where due attention is devoted to making sure that all notches are located approximately on the longitudinal centerlines of the protective packaging sections involved. -
FIG. 2 shows how a flexible tube may be formed from aflat strip 3 of material. A forming shoulder 25, the inner surface of which and the outer surface of the tube 1 are separated by a narrow slit, is formed around the tube 1 shown inFIG. 1 . Thestrip 3 of material that is horizontally fed in is guided between a pair ofrollers 26 that drive it at that location, and is then guided around anidler roller 27 and transported upward at an oblique angle, where thestrip 3 of material is guided through the slit between the forming shoulder 25 and the tube 1, and thereby wrapped around the outer surface of the tube 1. The downward drawing of the strip of material may be executed by means of rollers, drums, or similar, which are not shown here. Theflat jaw 5 then joins the overlapped edges of thestrip 3 of material, as has been mentioned above in conjunction withFIG. 1 . - Of course, that which has been depicted in
FIG. 2 for thestrip 3 of material also applies to thestrip 13 of material utilized for manufacturing the protective packaging. -
FIG. 3 depicts a sectioned view illustrating how thestrip 3 of material is arranged in the schematized apparatus shown inFIG. 2 in order to form the inner packaging. An edge of thestrip 3 of material is folded over in order that thestrip 3 of material will have a double layer section extending along the fold line. A foldededge 28 will therefore be formed in the interior of the section of flexible tubing formed thereby. Theopposite edge 29 of thestrip 3 of material is then positioned over the outer layer of the double layer section and joined to its outer layer along its entire length. Azone 32 extending between thatedge 30 of thestrip 3 of material and the formeropposite edge 31 of thestrip 3 of material is left loose. - This
loose zone 32 on thestrip 3 of material may be utilized for joining it to thestrip 13 of material used for manufacturing the protective packaging. -
FIG. 4 depicts a sectioned view of aninner packaging 11. Here, once again, we can see the type of joint binding together the twoedges strip 3 of material, i.e., the joint explained above in conjunction withFIG. 3 . Alayer 33 of adhesive that joins said edges is applied between the outer layer of the folded-over edge of thestrip 3 of material and the inner surface of the opposite edge. Adhesive is then also applied to theloose zone 32 on thestrip 3 of material (cf. the arrows A). The entire assembly is then joined to the protective packaging, where a layer of adhesive 34 is used to join the inner surface of the protective packaging to theloose zone 32 on the inner packaging. Here again, an edge of thestrip 13 of material utilized for manufacturing the protective packaging is folded over outward and said outwardly folded-over portion is joined to the inner surface of the opposing edge by means of alayer 35 of adhesive. Said joining of the inner packaging to the protective packaging occurs at one end of the protective packaging only. - The result of manufacturing a single packaging is shown in
FIG. 6 . The protective packaging, which, to users, would initially appear to be merely a uniform object, is longitudinally extended and has a graspingtab 36 on both of its ends. Said graspingtabs 36 are formed on either side of the separation zone by theseparating mechanism 18 shown inFIG. 1 . The protective packaging has a sort ofperforation 37 that has been generated by theapparatus 22 shown inFIG. 1 situated approximately midway between its ends. Apart from that, saidperforation 37 need not be visible to users. Whether an actual perforation or notching is involved will depend on the circumstances of the individual case involved or the foodstuff that is to be packaged. - If the user now grasps the pair of grasping
tabs 36 and tears open the packaging by pulling on it along the direction of the arrows, the situation shown inFIG. 7 , where the inner packaging becomes visible, will occur. Since theinner packaging 11 is joined to theprotective packaging 21 in the vicinity of one of its ends (cf.FIG. 5 ), theinner packaging 11 will remain contained within the right-hand part of theprotective packaging 21 shown inFIG. 7 . It therefore will not fall out. The inner packaging may continue to be handled by grasping the graspingtab 36 on that part of the protective packaging that is joined to theinner packaging 11. If semi-luxury goods, for example, tea, are involved, the user may insert the inner packaging into a cup without having to handle theinner packaging 11. He/she may also utilize thegrasping tabs 36 for removing the teabag from the cup once the desired brewing period has elapsed. - As an example, it will now be assumed that the packaging involves tea, i.e. a sort of teabag. The strip of material utilized for manufacturing the inner packaging will then be a double layer strip, where what will later become the inner surface of the inner packaging consists of a thermoplastic and what will later become its outer surface consists of cellulose fibers.
- Employing the joint between the inner packaging and the protective packaging makes it possible to dispense with mechanical fasteners.
- Of course, the thermoplastic portions of the associated
strips FIGS. 4 and 5 , which would eliminate the need for employing an additional adhesive. - In the case of teabags, a mechanical knife might be utilized for producing the string of perforations 37 (cf.
FIG. 6 ). In the case of coffee products that must be treated in different ways, the strip of material utilized for manufacturing their protective packaging may be weakened by a laser system so as to form a weakened line, without affecting the barrier layer.
