Closure Device for a Bottle

Abstract

A closure device ( 11 ) for a bottle comprising an attachment means ( 14 ) which attaches to the neck ( 21 ) of a bottle and comprises a sleeve portion ( 33 ) having an inner surface ( 20 ) with a thread configured to engage with an external thread on the neck of the bottle and a main body ( 25 ) having a pump portion with a pump ( 26 ), whereby the device is able to attach to the bottle by screwing the attachment means onto the bottle neck to enable the pump to be used to extract air from the bottle. In another embodiment instead of a pump, the main body may include a pour portion to assist in pouring of contents of the bottle including a cover portion for covering the opening to the mouth of the bottle.

1 . A closure device for a bottle comprising an attachment means including an inner wall with a screw thread which screws onto an external screw thread of a bottle and a first coupling portion; and a main body with a functional part and including a second coupling portion which couples with the first coupling portion whereby the attachment means is able to rotate around the neck of the bottle independently of the main body, and wherein the second coupling portion fits at least partially within an annular channel of the first coupling portion and is retained within the annular channel by a retainer of the first coupling portion.  
   
   
       2 . The closure device as claimed in  claim 1  wherein the main body includes a sealing means for insertion in a mouth of the bottle and providing a seal with the inner surface of the neck of the bottle.  
   
   
       3 . The closure device as claimed in  claim 1  wherein the first coupling portion comprises a male or female portion and the second coupling portion comprises a matching female or male portion.  
   
   
       4 . The closure device as claimed in  claim 1  wherein the annular channel is located between inner and outer walls of the attachment means.  
   
   
       5 . The closure device as claimed in  claim 1  wherein the second coupling portion comprises an annular skirt which fits at least partially within the annular channel.  
   
   
       6 . The closure device as claimed in  claim 1  wherein the first coupling portion is configured with an upper retainer to retain the skirt within the annular channel.  
   
   
       7 . The closure device as claimed in  claim 1  wherein the upper retainer comprises an annular rim.  
   
   
       8 . The closure device as claimed in  claim 5  wherein the skirt is configured with a lower peripheral rim which is configured to engage with the retainer to prevent upward movement of the skirt relative to the attachment means.  
   
   
       9 . The closure device as claimed in  claim 5  wherein the skirt is configured to be able to move vertically within the channel.  
   
   
       10 . The closure device as claimed in  claim 1  wherein the attachment means comprises an annular member with an inner surface which is able to slide down the neck of a bottle to engage a screw thread of the neck of the bottle.  
   
   
       11 . The closure device as claimed in  claim 1  wherein the second coupling portion extends from a lower end portion of the main body and comprises a collar extending around a central cylindrical portion of the main body.  
   
   
       12 . The closure device as claimed in  claim 1  wherein the main body comprises a pump for extracting air from the bottle to which the device is attached.  
   
   
       13 . The closure device as claimed in  claim 1  wherein the main body comprises a pour portion to assist with pouring of the contents of the bottle.  
   
   
       14 . A closure device for a bottle comprising an attachment means which attaches to the neck of a bottle and comprises a sleeve portion having an inner surface with a thread configured to engage with an external thread on the neck of the bottle and a main body including a pour portion to assist with pouring of contents of the bottle, and including an aerator comprising a wall with a series of apertures and a passage for coupling with a tube which extends downwardly from the device and through the neck of a bottle to which the device is attached.  
   
   
       15 . The closure device as claimed in  claim 14  wherein the apertures arranged radially around the passage.  
   
   
       16 . The closure device as claimed in  claim 14  wherein the main body comprises a central downwardly extending spigot with the passage therethrough.  
   
   
       17 . The closure device as claimed in  claim 16  wherein the apertures are in the form of slanted radial slits.
