Abstract

Abstract A container closure attachable directly or indirectly to a container neck sealed by means of a pierceable film seal. The provision of a film seal covering the container neck guarantees the user that the contents of the container are authentic and original as supplied by the manufacturer. The film seal is pierced as the closure is adjusted from an intact to an access position on the container neck. In the upper intact position, a safety band remains intact. The closure can be adjusted to the lower access position only after the safety band has been removed, and the film seal is pierced as the closure is adjusted to the lower access position. Ratchet-like serrations may be provided on the inner side of the safety band engaging the container, thus making it impossible to unscrew a screw-type closure without removing the safety band. The safety band may be provided on a separate intermediate piece which may be snap-fitted or screwed onto the container neck. Opening means for piercing the film seal may be provided on the intermediate piece.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 135 words
Plastic closure comprising a base with a pouring opening arranged therein and a cap connected to the base by means of a film hinge, the closure being positioned on a container neck closed by a per- foratable diaphragm or foil (6, 60, 601), either directly or accompanied by the interposing of an adaptor, characterized in that at least part of the closure is kept by securing means in an upper guarantee position with respect to the upper edge of the container neck and only after removing the breaking away the securing means (44, 204, 403) can be brought into a lower use position and that on the base or on the adaptor (2, 20) are provided means for cutting (208, 209) or pushing (43, 201) through the diaphragm or foil (6,60,601) closing the container neck.
Claim 2
Dependent Claim 135 words
Plastic closure comprising a base with a pouring opening arranged therein and a cap connected to the base by means of a film hinge, the closure being positioned on a container neck closed by a per- foratable diaphragm or foil (6, 60, 601), either directly or accompanied by the interposing of an adaptor, characterized in that at least part of the closure is kept by securing means in an upper guarantee position with respect to the upper edge of the container neck and only after removing the breaking away the securing means (44, 204, 403) can be brought into a lower use position and that on the base or on the adaptor (2, 20) are provided means for cutting (208, 209) or pushing (43, 201) through the diaphragm or foil (6,60,601) closing the container neck.
Claim 3
Dependent Claim 84 words
Closure according to claim 1, characterized in that the closure can be brought from the guarantee position into the use position with the aid of a thread on the base, and that on the latter is provided a guarantee band (204, 205), which can be peeled or tom off, said base cooperating with a ratchet part (505) located on the container neck and which renders impossible the unscrewing of the closure for as long as the guarantee band is connected to the base (Fig.4).
Claim 4
Dependent Claim 96 words
Closure according to claim 1, characterized in that it is kept in an upper guarantee position and in a use position with the aid of locking members (202, 402, 503), which are operatively connected to one another and fitted to the container neck or adaptor and on the inside of the base, the locking members permitting an axial pushing of the closure into the guarantee and use position, but preventing a removal thereof, the guarantee position on the base or adaptor (204, 403) being secured by a guarantee band, which can be peeled or torn off.
Claim 5
Dependent Claim 24 words
Closure according to claim 1, characterized in that the container is closed by a diaphragm (405) shaped in one piece with the adaptor (400).
Claim 6
Dependent Claim 23 words
Closure according to claim 1, characterized in that the container is closed by a foil (6, 60) directly applied to the container neck.
Claim 7
Dependent Claim 23 words
Closure according to claim 1, characterized in that the container neck is closed by a circular adaptor (40) provided with a foil (60).
Claim 8
Dependent Claim 24 words
Closure according to claim 1, characterized in that the means for perforating foils (60) comprise a hollow mandrel (201) connected to the pouring opening.
Claim 9
Dependent Claim 36 words
Closure according to claim 1, characterized in that the means for cutting through the foil (60) comprises a cutting tooth (208), whose tip (208) cuts through the foil and whose edge (209) forces same radially outwards.
Claim 10
Dependent Claim 33 words
Closure according to claim 1, characterized in that the adaptor (4) is provided with a cutting device (43), which can be operated by a hollow push rod (21) connected to the pouring opening.
Claim 11
Dependent Claim 24 words
Closure according to claim 1, characterized in that the adaptor (40) has a central opening, whose diameter corresponds to that of the mandrel (201).
Claim 12
Dependent Claim 21 words
Closure according to claims 5 and 8, characterized in that the diaphragm (405) of the adaptor (400) has weakening lines (406).
