Container cap

Abstract

Disclosed herein is a container cap allowing the addition of an adjunct. The container cap includes a base cap member, which is a lower cap body coupled to a neck part of a container, an operational cap member, which is an upper cap body coupled to the upper end of the base cap member, and an openable sheet, which is provided on the lower end of one selected from the base cap member and the operational cap member. The openable sheet is able to be cut to discharge the adjunct. The container cap further includes a cutting means for cutting the openable sheet. The cutting means is provided in a remaining one selected from the base cap member and the operational cap member at a position corresponding to the openable sheet. The openable sheet includes a weight member, which has a diameter less than a diameter of an arc part of the openable sheet to be cut. A connection rib is connected between the weight member and a lower edge of an adjunct receiving part of the base cap member. The openable sheet further includes an openable sealing film, which seals both the lower edge of the adjunct receiving part and the weight member.

1 . A container cap allowing addition of an adjunct, and comprising a base cap member, which is a lower cap body coupled to a neck part of a container, an operational cap member, which is an upper cap body coupled to an upper end of the base cap member, an openable sheet provided on a lower end of one selected from the base cap member and the operational cap member, the openable sheet being cut to discharge the adjunct, and cutting means for cutting the openable sheet, the cutting means being provided in a remaining one selected from the base cap member and the operational cap member at a position corresponding to the openable sheet, wherein
 the openable sheet comprises: a weight member having a diameter less than a diameter of an arc part of the openable sheet to be cut, with a connection rib connected between the weight member and a lower edge of an adjunct receiving part of the base cap member; and an openable sealing film for sealing both the lower edge of the adjunct receiving part and the weight member.   
   
   
       2 . The container cap as set forth in  claim 1 , wherein a band-shaped space is defined between the lower edge of the adjunct receiving part and a circumferential outer edge of the weight member, so that a cutting blade of the operational cap member is moved along the band-shaped space. 
   
   
       3 . The container cap as set forth in  claim 2 , wherein the connection rib comprises a plurality of connection ribs disposed adjacent to each other in the band-shaped space to connect the lower edge of the adjunct receiving part and the circumferential outer edge of the weight member to each other. 
   
   
       4 . The container cap as set forth in  claim 1 , wherein the weight member comprises a weight body having a predetermined weight such that, when the openable sheet is cut, the openable sheet is rotated downwards around the connection rib, which serves as a hinge.
