Abstract

The container (2) is provided with a cap (1) that comprises a first component in a plastic material (3) defined by an annular body that in correspondence to a longitudinal edge section has an annular cavity (8) defined by two sections (11 and 12) separated by an annular shoulder (14), a folded edge (13) of a mouth (9) of the container (2) being housed in a snap-fit manner inside the cavity (8), and a second component in a metal material constituted by a metal capsule (4) in the so-called "twist off" zone already screwed onto the first component (3) when the cap is fitted (1).

Description

  • The present invention concerns a container provided with an improved cap.
  • As is known, certain types of metal containers and those in other materials have a metal capsule in the so-called "twist off" zone as a lid. This capsule has a crimped lower edge and a plurality of helical ridges obtained along this edge in a uniformly distributed manner. In use, the lid is screwed onto the mouth of the container, a mouth that has a thread. At present, in the industrial sector, the phase of filling the container with a product and the successive phase of screwing on the lid is carried out using automatic systems that, regarding this last phase of closing, are equipped with a container gripper device, a lid gripper device and a device that first moves the lid close to the mouth of the container and then rotates the lid with respect to the container in order to accomplish the screwing on. The complexity and related cost of an automatic system that must carry out the above-described operations appear evident. In addition, the system must first of all ensure perfect centring between the lid and the mouth of the container in order to allow correct coupling between these two elements and then the required torque to correctly screw the lid on without damaging the container; for example, consider containers in a deformable material such as certain types of metal containers. It should be pointed out that for many products, perfect air and liquid tightness is required. Lastly, it is evident how the above-mentioned system is much more complex when the mouth of the container is defined along an axis other than the longitudinal vertical axis of the container.
  • The object of the present invention consists in making a container provided with an improved cap that is devoid of the above-mentioned drawbacks.
  • According to the present invention, a container is made that is provided with an improved cap, characterized in that the cap comprises:
    • a first component in a plastic material defined by an annular body that in correspondence to a longitudinal edge section has an annular cavity defined by two sections separated by an annular shoulder, a folded edge of a mouth of said container being housed in a snap-fit manner inside said cavity, and
    • a second component in a metal material constituted by a metal capsule in the so-called "twist off" zone already screwed onto said first component when said cap is fitted to said container.
  • The present invention shall now be described with reference to the enclosed drawings, which show several preferred embodiments and where:
    • Figure 1 is a partial, perspective view of a container made according to the principles of the present invention,
    • Figure 2 is an enlarged-scale cross-section view of the coupling between a cap and the container in Figure 1,
    • Figure 3 is a partial view of a first element of the cap in Figure 2,
    • Figure 4 is a view of a second element of the cap in Figure 2,
    • Figure 5 is a cross-section view of a second embodiment of the cap shown in Figure 2, and
    • Figures 6 to 11 are cross-section views of further embodiments of the cap in Figure 2.
  • With reference to Figure 2, reference numeral 1 indicates, in its entirety, a cap to apply on a mouth 9 of a container 2 made of metal, plastic or any other material, as shown in Figure 1. The cap 1 is defined by a first component in a plastic material 3 and a second component in a metal material constituted by a metal capsule 4 in the so-called "twist off" zone and shown in Figure 4. As is known, the so-called "twist off" capsule 4 has a crimped lower edge 5 and a plurality of helical ridges 6 are obtained along this edge 5 in a uniformly distributed manner. The first component 3 is defined by an annular body on the outer cylindrical wall of which the helical ridges 7 are obtained as shown in Figure 3. The capsule 4 is screwed onto the first component 3 and, in substance, the ridges 6 of the capsule 4 are screwed along the ridges 7 of the first component 3.
  • With reference to Figure 2, the first component 3 has an annular cavity 8, in correspondence to one of its longitudinal ends, defined by two lateral walls 8a and 8b of which wall 8a is the innermost wall and by a bottom wall 8c. A first section 11 is defined inside the cavity 8 with decreasing width towards the inside so as to constitute a guide as shall be better explained further on and a second inner section 12 able to be engaged by a folded edge 13 of the mouth 9, as an annular shoulder 14 made in the wall 8a is defined between sections 11 and 12. In the embodiment shown in Figures 1 and 2, the mouth 9 is constituted by a cylindrical collar 15, the upper section of which is folded back to form said edge 13, which has a truncated-cone shape. The edge 13 is folded towards the inside of the mouth 9 and in section is defined on a plane on which it defines an acute angle with the collar 15.
  • In use, after the product has been placed in the container 2, the mouth 9 of this container 1 is brought below a magazine (not shown) of caps 1. A cap 1 is taken from this magazine and applied with pressure to the mouth 9. During this application, the edge 13 of the collar 15 enters into the cavity 8 and elastically deforms the wall 8a until the edge 13 is inside section 12 where its free end snaps onto the annular shoulder 14 while the fold point makes contact with the wall 8c. Basically, a snap coupling between the cap 1 and the mouth 9 has been created.
  • A second embodiment of the cap 1 is shown in Figure 5, which contemplates the realization of an inner wall 16 made in a plastic material and integral with the first component 3. The wall 16 lies on a plane orthogonal to the longitudinal axis of the first component 3 to close the inner section of the latter. A notch 17 is made along the connection edge between wall 16 and the inner wall of the first component 3. Naturally, the notch 17 could also be made close to the connection edge between wall 16 and the inner wall of component 3. In addition, a tab 18 is fixed to the outer face of wall 16, always integral with wall 16, to be used as a grip for pull-tab opening, which consists of detaching wall 16 from the first component 3 by pulling it off. In this embodiment, the edge 13 has a cylindrical shape and, in section, is actually defined on a plane parallel to that of the collar 15, with which it is connected by a central section that is curved in Figure 5, but could also be straight.
  • Figure 6 shows a third embodiment of the cap 1 used when the mouth 9 is similar to that shown in Figure 2, but envisages that the edge 13 is folded towards the outside of the mouth 9. In this case, the annular shoulder 14 is obtained on the outermost lateral wall 8b of the cavity 8.
  • A fourth embodiment of the cap 1 is shown in Figure 7 that is similar to that shown in Figure 5, but without the wall 16 and the tab 18.
  • A fifth embodiment of the cap 1 is shown in Figure 8 that is similar to that shown in Figure 6 and in which the edge 13 of the collar 15 is folded towards the outside and, in section, is parallel to the collar 15. It is obvious that the edge 13 could have further geometric developments, such as curls and so on for example.
  • A sixth embodiment of the cap 1 is shown in Figures 9, 10 and 11 that is suitable for collars 15 having two cylindrical sections 15a and 15b of different diameters and therefore defining an annular shoulder 15c between them and, in particular, with section 15a, which is the one that originates from the upper wall of the container 2, being the one of largest diameter. The longitudinal length of wall 8a is greater than that of wall 8b and an annular shoulder 21, onto which the annular shoulder 15c snaps, is obtained on wall 8a. Here, both walls 8a and 8b of the cavity 8 have an annular shoulder 21 and 14 onto which the annular shoulder 15c and the edge 13 of the collar 15 snap. Furthermore, the free end of wall 8a is of decreasing thickness so as to define a guide 19 for insertion of the collar 15 into the cavity 8. In Figure 9, the edge 13 is similar to that shown in Figure 6, in Figure 10 the edge 13 is similar to that shown in Figure 8, while in Figure 11 the edge 13 has a curled shape in cross-section.
  • From that described above, the advantages obtained with the embodiment of the present invention are evident.
  • In particular, a cap 1 has been created that can be applied on the mouth 9 of a press-fit container 2, i.e. by applying a direct force on the cap 1 directed towards the mouth 9. It is immediately obvious that in using such a cap 1, the coupling between cap 1 and mouth 9 does not need particularly complex automatic machinery, as it is sufficient to just press the cap 1 onto the mouth 9. It should also be underlined that this coupling does not create any problems or the need for special stratagems according to the material used to produce the container 2 and the same observation can also be made with regard to the position of the mouth 9 with respect to the longitudinal axis of the container 2. Furthermore, by using such a cap 1, the coupling between cap 1 and mouth 9 does not require precise centring between cap 1 and mouth 9 as one or more guides are defined in the cap 1 for the folded edge 13 of the mouth 9. Lastly, it should be noted that the cap 1 can be used for collars 15 that have edges 13 folded in different ways (angled or not, internal or external).
