Embodiment Construction

[0082] As shown in FIGS. 5 and 6 , the cap 1 is connected to the neck 2 of the container 3 .

[0083] The cover 1 can be made of plastic material, for example by injection molding or compression molding of plastic.

[0084] The container 3 comprises a substantially cylindrical first wall 4 and a substantially cylindrical second wall 5 arranged substantially coaxially, the diameter of the second wall 5 being smaller than the diameter of the first wall 4 .

[0085] The first wall 4 has a substantially constant thickness, which forms the dispensing end of the container 3 .

[0086] Between the first wall 4 and the second wall 5 is an annular wall 6 which extends transversely to the second wall 5 forming a neck ring 7 .

[0087] As shown in Figure 11, a variant of the container 3 is shown, in which a protrusion 25 extends from the first wall 4, this protrusion is intended to interact with the lid 1, which will be described in detail below.

[0088] The protrusion 25 comprises a ...

Abstract

A pressure cap comprises a closing part (8) associable with an opening (30) of a container (3) , engaging means (10) associable with a neck (2) of said container (3) , said engaging means (10) being provided with retaining means (11) for engaging in a projection (7) of said container, a line of intended opening (15) in said engaging means (10) interposed between a side body (12) of said engaging means (10) and said closing part (8) , said line of intended opening (15) being defined by fracturable means (16) , said line of intended opening (15) and said closing part (8) being positioned in relation to one another so that said fracturable means (16) breaks along said line of intended opening (15) when said closing part (8) is induced to detach itself from said side body (12) .

Description

technical field [0001] The present invention relates to caps, containers and methods of making and opening caps. Background technique [0002] The known pressure caps (200) in Figures 1 and 2 are made of plastic and they can be attached to the container (204). These caps comprise a closure portion (201) with a stop element (202) engaging the container neck (203). [0003] This known cap also has a tamper-evident ring (205) which surrounds the neck of the container before the cap is opened. [0004] The anti-theft ring is connected to the closure part of the lid by a breakable element. [0005] The anti-theft ring is also provided with a hooking element which prevents the closure part from being disengaged from the anti-theft ring and thus prevents opening of the container without destroying the breakable element. [0006] An accessory (206) convenient for the user to grasp protrudes from the anti-theft ring. [0007] By exerting force on the attachment it is possible to ...
