- The assembly process of the closure element (cap) to the container requires to have cooperating screw threads on these two parts of the packaging, or an equivalent means such as clipping cooperating elements.
- There is a need for an alternative system for efficiently and reliably attaching a closure element to a container.
- The technical problem mentioned above is met with a packaging comprising a container with a container body, and a container opening having an upper edge, and a closure for closing said container, the container and the closure being made out of polyethylene terephtalate (PET), polyethylene naphtalate (PEN), or a combination thereof, said container and said closure comprising respectively first and second attachment means According to the invention, the packaging is characterized in that:

- Preferably, the packaging according to the present invention further comprises tamper-evident means, said means preferably comprising a detachable tamper-evident band that is formed together with the closure, so that it catches one part of the container, thus preventing removal of the closure from said container, unless the said tamper-evident band is torn from the rest of the closure.
- Additional features and advantages of the present invention are described in, and will be apparent from, the description of the presently preferred embodiments which are set out below with reference to the drawings in which:
-
Figure 1 is a schematic cut profile view showing a packaging assembled according to the present invention, with attachment means not yet deformed ; -
Figure 2 is an enlarged schematic profile cut view showing the attachment means with one wall of the attachment groove that is deformed to permanently and leak-tightly catch the ring-shaped base of a closure ; -
Figure 3 is an partial profile schematic cut view showing how different parts of the packaging are assembled by rolling in conjunction with ultrasonic sealing ; -
Figure 4 is a schematic profile cut view showing the top portion of a packaging according to the invention, before the attachment means of the container are deformed to attach the closure element to said container ; -
Figure 5 is a perspective top view showing a closure element; -
Figure 6 is a perspective top view similar tofigure 4 ; -
Figure 7 is a view similar tofigure 4 , where a hinged overcap is partially open ; this figure illustrates the difficulty to pivot completely the overcap in open position when the walls of the spout and the over cap are tall ; -
Figure 8 is profile view showing the top portion of a packaging according to the invention, where the overcap comprises a tamper-evident detachable front tab ; -
Figure 9 is a view similar tofigure 8 , wherein the detachable front tab was removed in order to allow complete lifting of the overcap ; -
Figure 10 is a view similar tofigure 4 showing high closure walls. - As illustrated in
figure 1 , the invention concerns apackaging 1 comprising abottle 2 made from blow-moulding of a preform 3, thebottle 2 being closed by aclosure 4, and both thebottle 2 and theclosure 4 being made of polyethyleneterephtalate (PET). - In the present description, it can be seen from the drawing that
figure 1 represents a not yet blown bottle, so what is represented infigure 1 is the PET preform 3 that will later be blown into a full size bottle. - The
container 2 comprises acontainer body 5 and a container opening having an upper edge. Saidcontainer 2 and saidclosure 4 comprising first 8 and second 9 corresponding attachment means. - According to the invention, the second attachment means 9 are adapted in shape and size to cooperate with the first attachment means 8, and both attachment means 8, 9 are made of PET and integrally part of the rest of the pieces they are linked to - they could however be added to existing parts, by any means of linking, such as heat sealing, ultrasonic welding for instance -. More than that, both attachment means 8, 9 are adapted in shape and size to deform permanently by rolling to create a fluid-tight permanent arrangement between said
container 2 and saidclosure 4. - As can be seen from
figure 1 and figure 2 , the first attachment means is agroove 8 having one of itswalls 10 which is deformable by rolling, as illustrated infigure 2 . The second attachment means is an extending ridge 9 that is adapted in shape and size to be inserted into thegroove 8, such that the closure can be attached to the container in a water-tight arrangement by inserting the closure ridge into the container groove and permanently deforming thewall 10 of thegroove 8 so as to unremovably catch the ridge 9 intosaid groove 8. - Of course, the example described herein shall not be taken as a limiting example, and for instance the first attachment means of the closure could be a groove, whereas the second attachment means of the container could be a corresponding ridge (inverted positioning of the attachment means relative to the constitutive parts of the packaging.
- The
deformable groove wall 10 is about 1.5 mm thin so as to be more easily deformable during the rolling operation, and so as to avoid possible problems of cracking or whitening of the plastic material when the deformation is applied. The flexibility and permanent deformation of the material is made possible when the piece to be deformed is sufficiently thin so as to bend, up its point of permanent deformation, without stressing too much the plastic material. - As illustrated in
figure 1 , the closure element comprises a ring-shaped base and an overcap attached to the base. The closure's ridge extends from the lower edge of the ring-shaped base. The overcap is pivotably attached to the spout or, respectively, to the ring-shaped base, by a pivot hinge. The ring-shaped base is about 3 mm in height. - As shown in
figure 2 , the ridge 9 of the closure is disposed into thegroove 8 of the preform (or bottle) neck, and the latter is permanently deformed after the rolling operation, in a position that locks the ridge 9 into thegroove 8, so that theclosure 4 is permanently attached to the neck of thebottle 2. This attachment is a fluid tight attachment. - The groove is a U-shaped groove with a height of at least 2, preferably at least 3 mm, and a width sufficient to accommodate the ridge of the closure.
- The permanent deformation can be performed by punching, rolling, cold forming, hot forming, or a combination thereof. As illustrated in
figure 3 , the permanent deformation technique cited before can also be used in combination with ultrasonic welding, so that when the second attachment means is deformed to catch the first attachment means, in order to create a fluid-tight connection between said container and said closure, an additional ultrasonic welding step is performed to create a permanent seal between thecontainer 2 and theclosure 4. At the sealed interface between these two parts of the packaging, the plastic material is melted, and then colds back to its initial solid state, in such a way that the closure and the container form one single integral piece. Such a ultrasonic welding operation is performed in this case with a sonotrode, which also plays the role of a puncher that deforms the attachment means of the container, before (or at the same time) transmitting ultrasonic waves to seal the closure and the container together. - The permanent deformation of the PET or PEN is performed at a temperature comprised between 0°C and the glass transition temperature of the plastic material. This temperature of glass transition is well defined for both thermoplastics used in the present invention. For PET, the temperature of glass transition is Tg = 69°C. For PEN, this temperature of glass transition is Tg = 122°C. However, preferably the permanent deformation is applied at a temperature which is comprised in a more restricted range, and a range which is closer to ambient temperature, that is to say a temperature comprised between 18°C and 40°C, more preferably at a temperature comprised between 20°C and 30°C.
- In the example shown in
figure 3 , the attachment means of thebottle 2 is a circular ridge 9, that is deformed inwardly towards the centre of the bottle, and catches the attachment means of the closure, which is a horizontal extension 11 of theclosure skirt 12. - Actually, the attachment means of the container and/or the closure could be not entirely circular (i.e. all around the periphery), but rather on a portion of the circumference of the container and/or closure, or even at very specific points of the said container and/or closure.
- As illustrated in
figures 4, 5 and 6 , theclosure 4 can be a hinged closure, comprising abase ring 13 and anovercap 14 that is pivotably attached to thering 13 by ahinge 15. - As shown in
figure 4 , the lower part of thering 13 is disposed into agroove 8 of the bottle neck, before awall 10 of said groove is deformed to permanently catch thering 13, as described before. In that case and as shown infigure 5 and figure 6 , theovercap 14 is moulded as one integral piece with thering 13, but these two parts are linked viabreakable bridges 16, which are broken by tearing when the used first lifts theovercap 14 to open theclosure 4. This systems constitutes a tamper-evident means. - However, as shown in
figure 7 , there can be a problem for lifting theovercap 14 due to the functional dimensions of said overcap: in that case, it can be become impossible to lift the overcap as its front wall 17 will be stopped by thecontainer neck 18. - In order to avoid the potential problem illustrated in
figure 7 , the closure front wall 17 is preferably equipped with a detachablefront wall portion 19 as illustrated infigure 8 , that can be torn off before lifting theovercap 14 in open position of the closure, as shown infigure 9 . - This
detachable portion 19 is moulded as an integral portion of the rest of theclosure 4, but linked to the latter bybreakable bridges 16 of plastic material. This detachablefront wall portion 19 of the closure can be also integral to thering 13 of the closure (embodiment not shown in the drawing), or alternatively it can be also detachable from thering 13, as illustrated infigure 9 . - As shown in
figure 10 , a detachablefront wall portion 19 of theclosure 4, makes it possible for a verytall neck 18 of the closure which will still be closed with a hinged closure. - It should be understood that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the present invention and without diminishing its attendant advantages. It is therefore intended that such changes and modifications be covered by the appended claims.
