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.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates generally to container caps allowing the addition of adjuncts and, more particularly, to a container cap, which includes a base cap member, which is coupled to an opening of a container and has an adjunct receiving part, an operational cap member, which is coupled to the upper end of the base cap member, and an openable sheet, which is the bottom of the adjunct receiving part and comprises a weight member having a diameter less than that of the adjunct receiving part and an openable sealing film attached to the lower surface of the weight member and to the open lower end of the adjunct receiving part.[0003]2. Description of the Related Art[0004]In the case of techniques disclosed in Korean Patent Application Nos. 10-2003-023243 and 10-2004-002154, there is inconvenience in which, after a band is removed, a cap is rotated in a clockwise direction to discharge an adjunct and is thereafter rot...

AI Technical Summary

Benefits of technology

[0018]Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a container cap in which a weight member and an openable sealing film, which constitute an openable sheet, are coupled to the lower end of an adjunct receiving part that stores an adjunct, the weight member having a diameter less than that of the adjunct receiving part, so that superior sealing ability is ensured, and the openable sheet can be easily cut through a band-shaped space defined between the weight member and the adjunct receiving part, and in which, because the weight member and the openable sealing film are integrated with each other, the openable sealing film is prevented from being cut to shreds, thus enhancing the reliability of the product.

Problems solved by technology

In the case of techniques disclosed in Korean Patent Application Nos. 10-2003-023243 and 10-2004-002154, there is inconvenience in which, after a band is removed, a cap is rotated in a clockwise direction to discharge an adjunct and is thereafter rotated in a counterclockwise direction to open a container.

Furthermore, there is a problem in that the adjunct can undesirably solidify due to the permeation of moisture, gas pressure or physical action.

However, in the conventional container cap described above, because an edge part of the openable film is relatively thin, and because a method, in which the thin edge part of the openable film is cut by rotation of the cutting blade of the operational cap member to add the adjunct into the contents, is used, there is the possibility of the permeation of air or moisture, which dries or wets the adjunct and thus spoils it, through the thin edge part of the openable film.
