Container closure comprising a sound-producing means

Abstract

A closure for use with a pressurised container and configured to produce an opening sound is provided. The closure includes an openable closure member and an outer wrapping that covers at least a portion of the closure member tightly so that upon opening the closure member, content of the container escaping under the effect of the pressure deforms and/or forces open and/or sets vibrating the wrapping while producing a sound.

1 . A closure for a pressurised container for producing an opening sound, the closure comprising:
 an openable closure member; and   an outer wrapping that covers at least a portion of the closure member tightly so that upon opening the closure member, content of the container escaping under the effect of the pressure, which comprises gas and/or liquid, deforms and/or forces open and/or sets vibrating the wrapping while producing a sound.   
     
     
         2 . The closure according to  claim 1 , wherein the wrapper is configured to not totally enclose the container, but covers at least the closure member, and wherein the wrapper is formed as a cap. 
     
     
         3 . The closure according to  claim 2 , wherein upon opening the closure member, the content of the container escapes at least partially through a gap between an outer wall of the container and an inner surface of the cap, and the escaping container content produces sound by deforming or vibrating the wrapping. 
     
     
         4 . The closure according to  claim 1 , wherein the content of the container escaping under the effect of the pressure is set vibrating itself instead of or in addition to the wrapping, or only sets surrounding air vibrating. 
     
     
         5 . The closure according to  claim 1 , wherein at least part of the escaping content of the container and/or flow of air caused by this is conveyed through a space between an outer wall of the container and the wrapping to a sound-producing means. 
     
     
         6 . The container closure according to  claim 5 , wherein the sound-producing means are formed by a moulding of the wrapping and/or the outer wall of the container such that a sound is produced when the content of the container flowing out under the effect of the pressure strikes the moulding. 
     
     
         7 . The closure according to  claim 5 , wherein the sound-producing means comprises an object which is added between the wrapping and the outer wall of the container so that when the content of the container flowing out under the effect of the pressure strikes the object a sound is produced. 
     
     
         8 . The closure according to  claim 5 , wherein the sound-producing means comprises a breakthrough tongue or disintegrating tongue which is set vibrating by the escaping container content or the air flowing past. 
     
     
         9 . The closure according to  claim 5 , wherein the sound-producing means comprises a hole or flue pipe against which the escaping container content or the air flowing past is set vibrating. 
     
     
         10 . The closure according to  claim 5 , wherein the sound-producing means comprises a membrane which is forced open by the pressure of the escaping container content and produces a sound. 
     
     
         11 . The closure according to  claim 1 , wherein the container is a bottle. 
     
     
         12 . The closure according to  claim 1 , wherein the container is a bottle and the wrapping comprises a piece of tube made of an elastic material and can expand and has elasticity such that an upper part of the tube encloses the closure member tightly and a lower part of the tube reaches over a lower edge of the closure member and also encloses a neck of the bottle tightly such that upon opening the closure member, the content of the bottle escaping under the effect of the pressure escapes through an opening in the piece of tube produced upon opening the closure member or already made when producing the piece of tube, and in so doing causes a sound to be produced. 
     
     
         13 . The closure according to  claim 12 , wherein an edge of the tube and/or another part of the tube and/or the outflowing content of the container and/or surrounding air is/are set vibrating. 
     
     
         14 . The closure according to  claim 12 , wherein between the tube and an outer wall of the container there is an object which is added and/or the outer wall of the container is moulded such that when the container content flowing out under the effect of the pressure strikes the object or the moulding a sound is produced. 
     
     
         15 . The closure according to  claim 1 , wherein the container is a bottle and the wrapping is made from a thin, strong material which is shaped around an end of a neck of the bottle and the wrapping is shaped as a capsule, an edge of the capsule being connected to the neck of the bottle or at least placed tightly and dimensionally stablely against the neck of the bottle such that upon opening the bottle the pressure difference produced forces open the capsule before pressure equalisation can be implemented in any other way. 
     
     
         16 . The closure according to  claim 1  wherein the container is a bottle having a neck, and the wrapping is made from a thin, strong material that is shaped as a capsule that extends around the neck of the bottle, and wherein upon opening the bottle the content of the bottle escaping under the effect of the pressure escapes through a gap between an outer wall of the neck of the bottle and an inner wall of the capsule and in so doing produces a clear outflow sound by the capsule and/or the outflowing content of the container and/or surrounding air being set vibrating. 
     
     
         17 . The closure according to  claim 16  wherein the wrapping is shaped and/or folded such that against the shape or folding the outflowing content of the container and/or air flowing by produce a sound. 
     
     
         18 . The closure according to  claim 1 , wherein the closure member comprises a crown cap. 
     
     
         19 . The closure according to  claim 18 , wherein the crown cap is configured to be opened by turning the crown cap.
