Abstract
Description
- The present invention relates to a cap for opening/closing containers for pourable products. In particular, the cap in question is used preferably in those containers, parallelepiped in shape, that are produced by welding some layers of different materials such as, for instance, paper, polyethylene and/or aluminum, and that also has at least one breakable region, i.e. a surface portion that can easily be pierced, or cut or broken, in such a way as to permit fluid communication between the inside and the outside of the container.
- Such breakable region is produced by the elimination of one or more of said layers in different material, or alternatively, by the adoption of weakening lines predisposed on the surface of the container to facilitate opening the container while in the meantime maintaining the integrity of the preserved product inside.
- According to the known art, there are caps provided with perforation elements arranged to correspond to the breakable region and having a ribs or series of teeth that are able to pierce such a region when operated by the user during opening of the container.
- For instance, in
US 6354467 a cap is described for opening of such containers, comprising a collar constrained substantially around a breakable region and a perforation element for the breakable region that is hinged to said collar and rotatable with respect to this collar from a position external to said container to a position inside said container. The perforation element is provided with a system of three parallel ribs and arranged in such a way as to act on the breakable region along a plain profile substantially parabolic in shape. Furthermore, the central rib system is provided with a pointed extremity used to initially engrave the breakable region along a line of weakening predisposed on the latter. The cap in object is revealed to be particularly effective in the case of containers that have a breakable region having an external layer in paper and one or more inside layers in aluminum. - On the other hand, in the case of a breakable region having one or more layers produced in a particularly tenacious material, of the type, for instance, in polyethylene or in a material having analogous mechanical characteristics, a perforation element of the type described above would not be usable in an effective way because the same breakable region, submitted to the action of the perforation element, would deform by stretching without however being engraved by the pointed portions of the ribs of the perforator element, thus frustrating its effectiveness.
- One purpose of the present invention is to eliminate the drawbacks of the prior art by producing a cap provided with a structurally simple perforation element but which at the same time also guarantees opening of breakable regions produced with layers of material having characteristics of high strength, for instance, in polyethylene or in other analogous material.
- A further purpose of the present invention is to provide a perforation element of that, besides producing a perforation for points of the breakable region, allows the breakable region inclusive between two adjacent points of perforation produced by two consecutive teeth, to be cut.
- These and other purposes are achieved by the present cap for opening of a container for pourable products having a breakable region, said cap comprising a collar substantially fixed to said container for at least part of said breakable region and a perforation element that it is extended, at least partly, in correspondence of said breakable region and that is hinged to said collar and rotatable with respect to this between a position external to said container and a position inside said container. Advantageously, the cap is characterized by said perforation element being provided with at least one perimeter portion carrying a plurality of teeth projecting from the lower surface of the said perforation element and facing out onto the said breakable region of the said container when said perforation element is external to the said container.
- According to a particular aspect of the cap, one or more cutting edges that connect the adjacent sides are arranged between at least two consecutive teeth of said plurality of teeth.
- Furthermore, said one or more cutting edges are substantially parallel to said lower surface of said perforation element and in a lower position with respect to to the apical extremity of the teeth.
- Furthermore, all the teeth of said plurality have triangular profile and increase in height from the portion of the perforator element hinged to the collar to the opposite extremity of said perforation element, preferably following a parabolic law. In such a way, during opening of the container the tooth that is furthest away from the hinged portion is the first to touch the breakable region and to pierce it. Furthermore, the said cutting edges start to chop through the portions of the breakable region inclusive between two consecutive perforations produced by two adjacent teeth of the plurality of teeth. Such perforation and cutting operations by the perforator element continue until the perforation element is completely inside the container, having dragged the said breakable region inside with itself.
- A particular embodiment of the present invention will now be described by way of example and not limiting, with reference to the attached figures, in which:
- Figure 1 is a perspective view of the cap for opening of a container for pourable products;
- Figure 2a is a perspective view of the cap of figure 1, constrained to the container before opening the container;
- Figure 2b is a perspective view of the breakable region of the container for pourable products according to the invention around which the cap is constrained ;
- Figure 3 is a magnified view of the perforation element of the cap of figure 1;
- Figure 4 is a view from below of the cap according to the invention;
- Figure 5 is a view in longitudinal section of the cap of figure 1;
- Figure 6 is a view from above of the breakable region during the phase of opening.
- With particular reference to such figures, the generic cap for opening containers for pourable products according to the invention is indicated by 1.
- The
cap 1 includes acollar 2 fixed to the parallelepiped-shaped container 3, around a breakable region 4 on the upper face 3a of the latter container 3 and aperforation element 5 that extends completely in correspondence of said breakable region 4 and that is hinged to saidcollar 2 at one connectingextremity 6. Thecollar 2 has a substantially rectangular form, with two sharp cutting edges in the form of a parabola, and is glued in correspondence of aportion 60 that surrounds the breakable region 4. - Note that the breakable region 4 includes various layers of different materials, among which the more internal is, for instance, polyethylene of the linear or high-density type, which is extremely difficult to pierce or to cut. In this way the breakable region 4 is provided with high mechanical resistance owing to the high strength of the polyethylene, thus differentiating itself from the external surface in paper (or cardboard) that covers the container 3 completely and onto which the same collar is glued. As mentioned above, the known perforation elements would be ineffective on a breakable region produced in polyethylene, since they would not succeed in piercing and cutting this type of breakable region.
- According to the invention the
perforation element 5 is a parabola shaped plate and it is provided with a plurality ofteeth 6 that extend along theperimeter portion 7 of the same plate, taking the parabola form of theperforation element 5. The teeth 9 of the plurality ofteeth 6 project from thelower surface 8 of thesame perforation element 5 and lean out to the breakable region 4 of the container 3 when theperforation element 5 is still in a position external to the said container 3. Theperforation element 5 is able to rotate around theconnection extremity 6, with respect to saidcollar 2, between a position external to said container 3 and a position inside said container 3, cutting the breakable portion 4 and thus allowing the fluid to communicate between the inside and outside of the container 3. - Furthermore, each of the teeth 9 of said plurality of
teeth 6 is substantially triangular in profile, although teeth of different profile, for instance, trapezoidal or other analogous forms are possible, provided that they are pointed in form and able to provide equally for the perforation of the breakable region 4, as will become clearer from the description of the operation of theperforation element 5. - Furthermore, as Figure 5 shows, the
apical portions 12 of theteeth 6 are arranged to follow along a curvilinear profile S whose lower extremity M corresponds to thefree extremity 10 of saidperforation element 5. According to a particular embodiment of the invention not shown here, the heights of the teeth 9 increase from thehinged extremity 6 of theperforation element 5 up to thefree extremity 10 of the saidperforation element 5, substantially following a parabolic law. The two possible solutions foresee however that, during the rotation of theperforation element 5 around thehinged extremity 6, the first tooth 9 that comes into contact with the breakable region 4 is that on thefree extremity 10 of theelement perforator 5, i.e. in proximity of the lower extremity M of the curvilinear profile S, or, alternatively, on the vertex of the parabola drawn by theapical portions 12 of the teeth 9. - Furthermore, Figure 4 shows that between two consecutive teeth 9 of said plurality of
teeth 6 there is acutting edge 11 that connects theadjacent sides 15 of two teeth 9. In particular, according to the preferred embodiment described here, thecutting edge 11 is is substantially parallel to thelower surface 8 of theperforation element 5 and is reduced with respect to theapical portions 12 of the teeth 9. - Furthermore, the
cap 1 includes aprotection cover 16 hinged to one of theexternal extremities 2a of thecollar 2, in such a way that by a simple rotation it can be superimposed on and associate by interference and in a reversible way with theexternal cutting edges 2b of thecollar 2, before and after opening the breakable region 4 by theperforation element 5. - Furthermore, the effort that the
perforation element 5 produces on the breakable region 4 is transmitted by alever 20 that is hinged to a pivot ofrotation 21 integral with thecollar 2 and extending between twoopposite sides 2b and 2c of the same. Thelever 20 rotates upwards and drags in rotation the perforation element constrained to thepivot 21 in correspondence to theconnection extremity 6. - Note that although one particular embodiment of the invention is described here, in which a lever is included in the cap for facilitating the action of the perforation element, a possible cap in which such lever is not present and the action on the perforation element is produced directly by the hand by the user, still comes within the scope of protection of the present patent. In the latter case, the extremity of
connection 6 of theelement perforator 5 and the pivot ofrotation 21 coincide in a single element that is arranged along an inside cutting edge of thecollar 2. - In use, the
perforation element 5, either operated indirectly by the use of theaforementioned lever 20, or operated directly by hand pressure of the user, is made to rotate toward the breakable region 4 in such way that the teeth 9 of the plurality ofteeth 6 begin to pierce the breakable region 4 in a point to point way, substantially describing a parabola, as shown in Figure 6. - Furthermore, when the teeth 9 have entered the container 3 for a certain distance, meeting the
cutting edge 11, the latter starts to cut theportions 30 of the said breakable region 4 inclusive between twoconsecutive perforations 29 produced by two adjacent teeth 9 of said plurality ofteeth 6. - In this way the breakable region 4 is also cut after being pierced, starting from the portion of the breakable region furthest from the
connection extremity 6 of the perforation element and terminating in close proximity to theconnection extremity 6. The final shape of theportion 100 of breakable region 4 cut is parabolic, thus reflecting the shape of theperforation element 5. - At the end of the rotation, the
perforation element 5 is completely inside the container 3, having dragged theportion 100 of the said breakable region 4 - or rather the subject of the action of the perforation element 5 - into the container 3 with itself.
