CLOSING CAP ASSEMBLY

Abstract

A closing cap assembly (12) for being disposed on a discharge opening (11) of a container (10 includes a multi-piece design, having a protective cap (13) and a collar (14) which is designed as a sleeve, the protective cap (13) and the collar (14) being intended to be disposed on the discharge opening (11), the protective cap (13) having an inner cap (19) which is housed in an enveloping cap (18) and is connected to the enveloping cap (18) via a connective element (28). The connective element serves for establishing a detachable connection to the collar (14) independently of the inner cap (19).

Description

BRIEF DESCRIPTION OF DRAWINGS

[0019] In the following, a preferred embodiment of the closing cap assembly is described in further detail by means of the drawings.

[0020] FIG. 1 shows a longitudinal cut of a closing cap assembly disposed on a discharge opening of a container;

[0021] FIG. 2 shows an individual illustration and longitudinal cut of the closing cap assembly shown in FIG. 1;

[0022] FIG. 3 shows an exploded view of the closing cap assembly shown in FIG. 2.

DETAILED DESCRIPTION

[0023] FIG. 1 shows a longitudinal cut through a container 10 which is formed as a flacon in this instance and has a discharge opening 11 formed as a container neck, a closing cap assembly 12 being disposed on discharge opening 11. Closing cap assembly 12 has a multi-piece design having a protective cap 13 and a collar 14 which is formed as a sleeve, is disposed on discharge opening 11 and surrounds a dosing pump device 15 disposed in discharge opening 11. Dosing pump device 15 is crimped to an opening edge 16 of discharge opening 11 by means of a fastening sleeve 16 which is housed between discharge opening 11 and collar 14.

[0024] As in particular a combined view of FIGS. 2 and 3 shows, protective cap 13 has an inner cap 19 disposed in an outer enveloping cap 18, a gap formed between enveloping cap 18 and inner cap 19 housing a cap insert 20 in the present instance. Enveloping cap 18 is made in two pieces in the present instance and has an outer sleeve 22 provided with a cap bottom 21 and an inner sleeve 23 which engages in outer sleeve 22 and has a support collar 24.

[0025] In the present instance, cap insert 20, which preferably simultaneously forms a cap weight and is made of an aluminum cast, forms a spacer which defines the axial relative position of enveloping cap 18 and inner cap 19. For this purpose, an, in this case, annular cap abutment 25 is formed at the upper end of cap insert 20, against which cap bottom 21 of outer sleeve 22 abuts, and an abutment collar 26 at the circumference of cap insert 20, against which inner sleeve 23 abuts with a sleeve edge 31. The connection between outer sleeve 22 and inner sleeve 23 takes place as a frictionally engaged connection in an engagement area 27 formed between outer sleeve 22 and inner sleeve 23.

[0026] To connect enveloping cap 18 to inner cap 19, a connective element 28 is provided which is made of a plastic material in deviation to enveloping cap 18 which is made of aluminum in compliance with inner cap 19 in the present instance. Connective element 28 has an annular body 29 having a support edge 30 which is oriented radially outward and rests on support collar 24 of inner cap 23 oriented radially inward. Furthermore, body 29 has an axial support web 32 which is at a radially inward offset and on which a lower support edge 33 of inner cap 19, which is oriented radially inward, rests.

[0027] As clearly shown by the marking of force transmission areas K1 and K2 in FIG. 1, which are formed between enveloping cap 18, connective element 28 and inner cap 19 when protective cap 13 is pulled from discharge opening 11 of container 10, connective element 28 is subjected only to pressure, meaning no separation forces become effective between support collar 24 of enveloping cap 18 and support edge 30 of connective element 28 as well as between support web 32 of connective element 28 and support edge 33 of inner cap 19, and connective element 28 is secured in its relative position between enveloping cap 18 and inner cap 19 via merely frictionally engaged connections 34 and 35.

[0028] To establish frictionally engaged connection 34, connective element 28 has an edge web 36 which extends axially from support edge 30 and is disposed concentrically to a clamping edge 37 of enveloping cap 18 also extending axially, ribs 40 extending axially on edge web 36 ensuring an increased clamping effect. To establish a clamping effect of connection 35 between a clamping web 38 disposed radially inward to edge web 36 and a clamping edge 39 of inner cap 19 extending in a gap formed between edge web 36 and clamping web 38, clamping web 38 is equipped with ribs 41.

[0029] As FIG. 1 shows, connective element 28 not only serves to connect enveloping cap 18 to inner cap 19 but also to connect protective cap 13 to collar 14 disposed on discharge opening 11. To establish the connection as interlocking connection 42, connective element 28 has a radially inner interlocking connection 43 on annular body 29, interlocking connection 43 being made of three interlocking protrusions 44 distributed equidistantly on the inner circumference of body 29 in the present instance, interlocking protrusions 44 being formed on clamping web 38 of connective element 28 in the present instance. In the locked position of FIG. 1, in which position protective cap 13 is fastened on discharge opening 11 or collar 14, interlocking protrusions 44 of interlocking member 43 engage behind an interlocking device 45 formed as a circumferential groove on collar 14, a lower support edge 46 of connective element 28 simultaneously resting on a container edge 47 formed as a container shoulder below discharge opening 11.

[0030] As FIG. 1 shows, connective element 28 connects a lower circumferential edge of enveloping cap 18 formed by support collar 24 in this instance to a lower circumferential edge of inner cap 19 formed in particular by support edge 33 in this instance, the connection being established in such a manner between connective element 28 and a lower portion of collar 14 that collar 14 of connective element 28 rests on container edge 37 in the connection configuration.

[0031] As FIG. 1 shows, connective element 28, which is formed independently of inner cap 19 of protective cap 13 and allows a detachable connection between protective cap 13 and collar 14 independently of the design or measurements of inner cap 19, allows inner diameter D of inner cap 19 to be chosen to be significantly larger than outer diameter d of collar 14—for example for housing larger dosing pump devices—without the connection between protective cap 13 and collar 14 being hindered by this.
