Device for pressing objects from blister packs

Abstract

A device ( 1 ) for use with a battery carrier ( 10 ) defining at least one sealed compartment ( 12 ) in which a product ( 14 ) is located and which is at least partly formed of a frangible material ( 20 ), the device ( 1 ) having a support for supporting the carrier ( 10 ) with the compartment ( 12 ) aligned with an aperture ( 8 ) in the support, and an engaging device for engaging with the compartment ( 12 ) whereby to break the frangible material ( 20 ) and displace the product ( 14 ) from the compartment ( 12 ) through the aperture ( 8 ). The support and the engaging device are normally spaced apart but are relatively movable to effect product ( 14 ) displacement, the support including at least one prong ( 15, 16 ) arranged in the aperture ( 8 ) in order to break the frangible material ( 20 ) when the engaging device displaces the product ( 14 ).

1 . A device ( 1 ) for use with a carrier ( 10 ) defining at least one sealed compartment ( 12 ) in which a product ( 14 ) is located, and which is at least partly formed of a frangible material ( 20 ), the device ( 1 ) comprising:
 supporting means for supporting the carrier ( 10 ) with the compartment ( 12 ) aligned with an aperture ( 8 ) in the supporting means; and   engaging means for engaging with the compartment ( 12 ) whereby to break the frangible material ( 20 ) and displace the product ( 14 ) from the compartment ( 12 ) through the aperture ( 8 ), the supporting means and the engaging means being normally spaced apart but being relatively movable to effect product ( 14 ) displacement,   wherein the supporting means comprise at least one prong ( 15 ,  16 ) arranged in the aperture ( 8 ) in order to break the frangible material ( 20 ) when the engaging means displaces the product ( 14 ).   
     
     
         2 . The device according to  claim 1 , wherein the at least one prong ( 15 ,  16 ) extends in a plane defined by the aperture ( 8 ). 
     
     
         3 . The device according to  claim 1 , wherein the supporting means comprise at least two prongs ( 15 ,  16 ) arranged in the aperture ( 8 ). 
     
     
         4 . The device according to  claim 3 , wherein the at least two prongs ( 15 ,  16 ) are arranged in opposite positions inside the aperture ( 8 ). 
     
     
         5 . The device according to  claim 1 , wherein the frangible material ( 20 ) comprises, preferably in totality, one of the following materials, such as plastic films or cardboard. 
     
     
         6 . The device according to  claim 5 , wherein the frangible material ( 20 ) forms a layer or a multilayer having a thickness between 0.01 to 0.5 mm for plastic, or up to 1 mm for cardboard. 
     
     
         7 . The device according to  claim 1 , wherein the at least one prong ( 15 ,  16 ) has a sharp end. 
     
     
         8 . The device according to  claim 1 , wherein the carrier ( 10 ) comprises a blister pack with a product ( 14 ), such as a battery, and the compartment ( 12 ) is pressed out of a base and is closed by the frangible material ( 20 ) extending across the base, the supporting means being arranged to support the pack with the compartment ( 12 ) upstanding thereon. 
     
     
         9 . The device according to  claim 1 , wherein the engaging means comprises a prominent member ( 5 ) which provides a face ( 7 ) arranged to initially engage an upstanding side edge of the compartment ( 12 ) under pressure so as to deform same and cause the product ( 14 ) to break the frangible material ( 20 ). 
     
     
         10 . The device according to  claim 1 , wherein the supporting means and the engaging means define spaced legs ( 2 ,  4 ) of a substantially U-shaped member, the aperture ( 8 ) of the supporting means being located towards a free end ( 9 ) of the respective leg ( 4 ). 
     
     
         11 . The device according to  claim 9 , wherein the prominent member ( 5 ) projects inwardly from a location towards a free end ( 3 ) of the other leg ( 2 ). 
     
     
         12 . The device according to  claim 10 , wherein the legs ( 2 ,  4 ) may be resiliently movable towards one another.
