- DESCRIPTION
The present invention relates to a closable airtight lid assembly.
The object of the invention is to provide a lid assembly which can be applied to containers having a certain rigidity but easily deformable, containing a product, designed to ensure perfect airtight closure of the product so that it retains its original properties, it being necessary for this lid assembly to be airtight even in the case where the contAiner is deformed.
A further ob~ect of the invention is that it must also be possible for the lid assembly to be applied to a packaging consisting of a small inner bag or container formed for example by a flexible sheet or film enclosing lS the product, and by an outer container having a certain rigidity but also ea~ily deformable, inside which said inner cont~iner is inserted, the lid assembly being connected to both the containers.
A further ob~ect of the invention i~ that it mu~t be poqsible for the lid assembly to be applied to a packaging consi~ting of a simple bag of flexible mate-rial.
Airtight lidq for product packaging are known, but they are not suitable for being connected for example to a contA;ner which i~ ea~ily deformable, nor with two different contAin~r8.
Lids of thi~ type compri~e a ~ingle element and form a seal with the opening of the container to which they are applied. Such a ~oining operation ha~ the drawback that, when the container i~ deformed, the airtightnesq of the closure is not guaranteed. Moreover, if the wrapper contAinin~ the product i~ inserted inside an outer contA~n~r, it i8 difficult to remove the product from the inner contAiner. In both cases, however, it i~
nece~sary to separate the lid from the contA~iner in order to open the resultant packaginq and this involves a certain incovenience durin~ use.
Other currently known lid assemblies which can be opened do not have, on the other hand, a good degree of airtightness on account of the imperfect adhesion between the respective walls of the movable part and of S the fixed part joined together, which is sufficient to cause the aforementioned loss of airtightness.
According to the invention, the closable airtight lid assembly is formed structurally by a movable lid, forming the actual clo~ing part, having along its entire periphery a channel-shaped cavity designed to receive a peripheral relief provided in a second element or small frame, the latter having a peripheral flange directed towards the inside, designed to delimit the opening of the packaging onto which the assembly is applied if necessary, either or both of the flanks of the peripheral relief having corrugations which cooperate with a wall or with both the vertical walls of the channel-shaped cavity provided in the movable lid element so that, when the two elements forming the assembly are brought into pressure-contact with each other, these corrugations, which havea certain flexibility, adhere perfectly to thi~ internal vertical wall of the channel-shaped cavity formed in the lid, providing an airtight ~eal between the two elements.
In order to improve further the airtightne~s of the closure, a gasket i8 located on the bottom of the channel-~haped cavity of the lid and come~ into operation when the lid i8 closed, poQitioning itself above the sm~ll frame.
More particularly, the present invention relates to an airtight, reclosable coffee package comprising:
a) a rectangular lid assembly wherein a lid and a frame are formed as a single molded piece, the 3S lid and frame being joined together by a weakened section which acts as a hinge and permits the lid to be placed in superposed relationship with the frame, the lid having along its entire periphery a rectangular h channel-shaped cavity, the frame having a flat, inwardly-extending flange with a central opening which delimits an access opening, said flat inwardly extending flange being connected to a rectangular peripheral relief by a steeply inclined section, said rectangular peripheral relief designed to be received in said channel-shaped cavity and having a peripheral channel underlying it, at least one of the flanks of the rectangular peripheral relief having flexible corrugations thereon which cooperate with a wall of the channel-shaped cavity of the lid so that when the two are brought into pressure-contact with each other the corrugations press against the wall of the channel-shaped cavity, providing an airtight seal between the two elements of the lid assembly;
b) a flexible bag fixed underneath the flat, inwardly-extending flange of the frame in an airtight relationship therewith, said flat inwardly-extending flange having a number of ribs underneath to ensure said airtight relationship, said flexible bag containing coffee in its interior and having provision for an opening to permit access to its interior through the access opening of the flange; and c) a rigid container enveloping said coffee-containing flexible bag and fixed within the peripheral channel of the frame.
In order to avoid accidental opening of the lid, pro~i~ion i~ made for the ~nap-engagement of two bo~se~
located on the contact wall~ of the lid and the ~mall frame respectively, positioned opposite the hinge.
The contour of the front part of the movable lid, oppo~ite the hinge, i~ ~lightly curved so that, when this movable element i~ clo~ed onto the ~mall frame, the two lateral front edge~ come into contact fir~t with the corre~ponding front edges of the small frame, thus en~uring preliminary engagement of these edges, followed by proper marrying of the entire contour of the front ,, ,~

b) a flexible bag fixed underneath the flat, inwardly-extending flange of the frame in an airtight relationship therewith, said flat inwardly-extending flange having a number of ribs underneath to ensure said airtight relationship, said flexible bag containing coffee in its interior and having provision for an opening to permit access to its interior through the access opening of the flange; and c) a rigid container enveloping said coffee-containing flexible bag and fixed within the peripheral channel of the frame.
In order to avoid accidental opening of the lid, pro~i~ion i~ made for the ~nap-engagement of two bo~se~
located on the contact wall~ of the lid and the ~mall frame respectively, positioned opposite the hinge.
The contour of the front part of the movable lid, oppo~ite the hinge, i~ ~lightly curved so that, when this movable element i~ clo~ed onto the ~mall frame, the two lateral front edge~ come into contact fir~t with the corre~ponding front edges of the small frame, thus en~uring preliminary engagement of these edges, followed by proper marrying of the entire contour of the front ,, ,~
2(~122S9 part of the mo~able lid onto the small frame.
This makes it easy to close the lid by exerting pressure on the middle point of the front part. This arrangement i-~ particularly suitable when the lid has a rectangular shape.
The small frame of the lid assembly according to the invention may be coupled either to a container possessing a certain rigidity,'but easily deformable, fixing the outer edge thereof, for example by means of adhesive, inside an external peripheral groove in the small frame, or to a wrapper of the flexible type, one of the faces of which is fixed, for example by means of adhesive, to the underlying part of the small frame itself provided with a flat flange delimiting the opening for acces~ to the packaging, or sLmultaneously to an outer contAiner and an inner contAiner consisting of a flexible wrapper.
The invention will now be de~cribed with refer-ence to the accompanying drawings which show a non-limiting example of embodiment of the said invention.
In the drawing~:
Figure 1 shows a plan view of the clo~able lid a~sembly according to the invention, in the open posi-tion;
Figure 2 ~how~ a plan view of the closed lid assembly;
Figure 3 show~, on a larger scale, along the cross-section III-III of Figure 1, the elements of the lid assembly im~gined as being di~connected from each other and located one above the other in an exploded position and, ~Figure 4 ~hows a front elevation of the lid ass~mhly with the' lid and the ~mall frame slightly removed from one another.
In Figure 1, the lid assembly, indicated overall by 2, comprises a fir~t element 10, constituting the lid proper, ~oined by means of a hinge 30 to a second element 40 constituting a sm~ll fram~ to which the packaging of the product is fixed. The hinge 30 is formed, integrally ~ 5 ~ 2012259 with the lid 10 and the small frame 40, from the same material from which they are made, by means of weakening of the material itself, for example mouldable plastic of suitable flexibility.
S The first element 10 of the assembly (see Figures 2 and 3) comprises an upper funnel 12 which forms, in the bottom part, a closed ring-shaped rim 14, the peripheral wall 16 of which delimits, together with the wall 18 of the lid, a channel-shaped cavity 20, the vertices of which are suitably rounded.
The small frame 40, having externally the same dimensions a~ the lid 10, forms an inner cavity 42 having at the bottom a flat flange 44 posses~ing an opening 45 for acce~s to the packaging, the walls of ~aid cavity 42 rising symmetrically along the entire periphery, with a first lower section 46 which is ~teeply inclined followed by a section 48 which is slightly inclined relative to the vertical, so as to form a relief 50 which is posi-tioned, when the lid is closed, inside the channel 20 of the lid.
The inclination of the connecting surface between the flange and the relief is particularly suitable for the application of the lid onto cont~in~r~ which contain granular products, 90 as to enable the latter to flow out more easily.
On the section 48 of the wall on the inside of the cavity 42 there i~ arranged a series of corrugation~
52 which p-~sqe~s a certain flexibility and cooperate with th-- ~nternAl vertical wall 16 of the channel-shap~d cavity 20 creating an airtight seal between the two elements of the- lid as~embly.
These corrugations 52 may also be present on the external peripheral wall 53 of the relief 50.
In order to improve further the airtightness of the clo~ure, a gaskQt 24 is provided on the bottom of the channel 20 ~u.lo~nding the rim 14 of the lid 10 80 as to form a further seal in abutment with the peripheral relief 50 of the small frame 40.
Below the flat flange 44 there are provided rib~
56 which promote leakproof fixing with the wall of a container (not shown), for example a bag with a product inside a flexible packaging, obtained for example by means of gluing with suitable adhesives.
In the case where the said flexible container is in turn inserted inside a second outer container, this additional container may be fixed by means of gluing in the external peripheral groove 60, formed between the inclined section 46 of the small frame and its external wall 54, and on which the ribs 62 project.
In order to avoid accidental opening of the lid part, provision is made for the mutual engagement of bosses 25 and 65 positioned, respectively, opposite the hinge, on the wall 18 of the channel 20 of the lid and on the wall 53 of the small frame while, ~o that the lid may retain a necessary degree of rigidity in view of the small thic~nesses adopted for the lid part, there are provided, 3y way of example, ribs 22 in the bottom part of the said lid.
For the opening of the movable lid 10, there is provided a tongue 26 located externally on the wall of the movable lid, in the region of the bo~s 25.
Finally, particularly in the case where the lid assembly ha~ a rectangular shape, provi~ion is made for the contour of the front part of the movable lid opposite the hinge, compriRing the wall 18 and the channel-~haped cavity 20, to be slightly convex in the vicinity of the bo~- 25 in such a way that, during closure of this moq~ble element onto the fr me, the two lateral front edg-a come into contact first with the corresponding front edge~ of the small frame thu~ ensuring preliminary engagement of the~e edges, followed by proper marrying of the entire contour of the front part of the movable lid onto the sm~ll frame. This slight convexity of the front part of the lid compri~ing said wall L8 and the channel-~hap~d cavity 20 is indicated by the play or camber 19 in Figure~ 3 and 4. This curvature, obt~ns~ for example by mean~ of hot air, will corre~pond to a camber of 2-3 mm, after cooling, in the middle part in the region of the _ 7 - 2~2Sg boss 25 for holding the lid in the closed position.
The closable lid assembly may be made of any material suitable for creating a hinge from the material itself, provided that it is not excessively rigid. By way of example, grade 15 polypropylene has advantageously been used.
The assembly may be made in any shape and size and may be applied to cont~iners for any product, made of cardboard, metal, plastic and the like, forming a single whole possessing perfect airtightness, being particularly recommended for products whose organoleptic qualities must be protected, such as for example vacuum-packed coffee, which tends to lose its aroma rapidly once the vacuum packaging has been opened.
This makes it easy to close the lid by exerting pressure on the middle point of the front part. This arrangement i-~ particularly suitable when the lid has a rectangular shape.
The small frame of the lid assembly according to the invention may be coupled either to a container possessing a certain rigidity,'but easily deformable, fixing the outer edge thereof, for example by means of adhesive, inside an external peripheral groove in the small frame, or to a wrapper of the flexible type, one of the faces of which is fixed, for example by means of adhesive, to the underlying part of the small frame itself provided with a flat flange delimiting the opening for acces~ to the packaging, or sLmultaneously to an outer contAiner and an inner contAiner consisting of a flexible wrapper.
The invention will now be de~cribed with refer-ence to the accompanying drawings which show a non-limiting example of embodiment of the said invention.
In the drawing~:
Figure 1 shows a plan view of the clo~able lid a~sembly according to the invention, in the open posi-tion;
Figure 2 ~how~ a plan view of the closed lid assembly;
Figure 3 show~, on a larger scale, along the cross-section III-III of Figure 1, the elements of the lid assembly im~gined as being di~connected from each other and located one above the other in an exploded position and, ~Figure 4 ~hows a front elevation of the lid ass~mhly with the' lid and the ~mall frame slightly removed from one another.
In Figure 1, the lid assembly, indicated overall by 2, comprises a fir~t element 10, constituting the lid proper, ~oined by means of a hinge 30 to a second element 40 constituting a sm~ll fram~ to which the packaging of the product is fixed. The hinge 30 is formed, integrally ~ 5 ~ 2012259 with the lid 10 and the small frame 40, from the same material from which they are made, by means of weakening of the material itself, for example mouldable plastic of suitable flexibility.
S The first element 10 of the assembly (see Figures 2 and 3) comprises an upper funnel 12 which forms, in the bottom part, a closed ring-shaped rim 14, the peripheral wall 16 of which delimits, together with the wall 18 of the lid, a channel-shaped cavity 20, the vertices of which are suitably rounded.
The small frame 40, having externally the same dimensions a~ the lid 10, forms an inner cavity 42 having at the bottom a flat flange 44 posses~ing an opening 45 for acce~s to the packaging, the walls of ~aid cavity 42 rising symmetrically along the entire periphery, with a first lower section 46 which is ~teeply inclined followed by a section 48 which is slightly inclined relative to the vertical, so as to form a relief 50 which is posi-tioned, when the lid is closed, inside the channel 20 of the lid.
The inclination of the connecting surface between the flange and the relief is particularly suitable for the application of the lid onto cont~in~r~ which contain granular products, 90 as to enable the latter to flow out more easily.
On the section 48 of the wall on the inside of the cavity 42 there i~ arranged a series of corrugation~
52 which p-~sqe~s a certain flexibility and cooperate with th-- ~nternAl vertical wall 16 of the channel-shap~d cavity 20 creating an airtight seal between the two elements of the- lid as~embly.
These corrugations 52 may also be present on the external peripheral wall 53 of the relief 50.
In order to improve further the airtightness of the clo~ure, a gaskQt 24 is provided on the bottom of the channel 20 ~u.lo~nding the rim 14 of the lid 10 80 as to form a further seal in abutment with the peripheral relief 50 of the small frame 40.
Below the flat flange 44 there are provided rib~
56 which promote leakproof fixing with the wall of a container (not shown), for example a bag with a product inside a flexible packaging, obtained for example by means of gluing with suitable adhesives.
In the case where the said flexible container is in turn inserted inside a second outer container, this additional container may be fixed by means of gluing in the external peripheral groove 60, formed between the inclined section 46 of the small frame and its external wall 54, and on which the ribs 62 project.
In order to avoid accidental opening of the lid part, provision is made for the mutual engagement of bosses 25 and 65 positioned, respectively, opposite the hinge, on the wall 18 of the channel 20 of the lid and on the wall 53 of the small frame while, ~o that the lid may retain a necessary degree of rigidity in view of the small thic~nesses adopted for the lid part, there are provided, 3y way of example, ribs 22 in the bottom part of the said lid.
For the opening of the movable lid 10, there is provided a tongue 26 located externally on the wall of the movable lid, in the region of the bo~s 25.
Finally, particularly in the case where the lid assembly ha~ a rectangular shape, provi~ion is made for the contour of the front part of the movable lid opposite the hinge, compriRing the wall 18 and the channel-~haped cavity 20, to be slightly convex in the vicinity of the bo~- 25 in such a way that, during closure of this moq~ble element onto the fr me, the two lateral front edg-a come into contact first with the corresponding front edge~ of the small frame thu~ ensuring preliminary engagement of the~e edges, followed by proper marrying of the entire contour of the front part of the movable lid onto the sm~ll frame. This slight convexity of the front part of the lid compri~ing said wall L8 and the channel-~hap~d cavity 20 is indicated by the play or camber 19 in Figure~ 3 and 4. This curvature, obt~ns~ for example by mean~ of hot air, will corre~pond to a camber of 2-3 mm, after cooling, in the middle part in the region of the _ 7 - 2~2Sg boss 25 for holding the lid in the closed position.
The closable lid assembly may be made of any material suitable for creating a hinge from the material itself, provided that it is not excessively rigid. By way of example, grade 15 polypropylene has advantageously been used.
The assembly may be made in any shape and size and may be applied to cont~iners for any product, made of cardboard, metal, plastic and the like, forming a single whole possessing perfect airtightness, being particularly recommended for products whose organoleptic qualities must be protected, such as for example vacuum-packed coffee, which tends to lose its aroma rapidly once the vacuum packaging has been opened.
