Abstract

A cap assembly mounted on a neck of a container for containing a ingredient different from that in accommodated in a container comprises a cap body having an inner housing formed with a chamber for storage of a secondary ingredient and a working member adapted to open a low end opening of the chamber to allow the secondary ingredient in the chamber of the inner housing to be mixed with a primary ingredient in the container. The mixed ingredients may be discharged through an opening.

Claims

1. A cap assembly mounted on a neck of a container for containing a ingredient different from that in accommodated in a container, comprising:

a cap body having an inner housing formed with a chamber;

a working member adapted to be assembled to a mouth of the cap body, which is formed with a opening and has an extended part at lower end thereof;

a lower sealing portion provided at the lower end of the extended part to seal a low end opening formed at the lower end of the inner housing; and

when the working member with the extended part is upwardly moved from the initial position for sealing the mouth and the opening, the low end opening is opened to drop a ingredient in the chamber into a container so as to be mixed with an another ingredient accommodated in the container and the mixture may be discharged from the opening.

2. The cap assembly in accordance with claim 1, wherein a perforated portion is formed below the upper end portion of the extended part, through which an ingredient may be filled into the chamber and then the perforated portion is sealingly covered a separate closing member.

3. The cap assembly in accordance with claim 1, wherein an upper end portion is formed above a perforated portion at the extended part and said upper end portion is adapted to close a upper opening formed at the mouth of the cap body, whereby the upper opening is opened to allow the mixture of ingredients to be discharged from the container.

4. The cap assembly in accordance with claim 1, wherein said lower sealing portion is formed as a separate part and is assembled to the extended part.

5. The cap assembly in accordance with claim 1, wherein said lower sealing portion is formed as a film type seal member.

6. The cap assembly in accordance with claim 1, wherein said working member assembled to a mouth of the cap body is adapted to be vertically moved to open the low end opening.

7. The cap assembly in accordance with claim 1, wherein said working member assembled to a mouth of the cap body is adapted to be vertically moved to open the low end opening by a long upwardly extended closing member.

8. A cap assembly mounted on a neck of a container for containing a ingredient different from that in accommodated in a container, comprising:

a cap body having an inner housing in which a chamber is formed;

a working member formed with a opening and assembled to a mouth of the cap body;

a lower sealing portion downwardly extended to sealingly contact with the low end opening, which is assembled to the working member, and

upon upward movement of the working member, said lower sealing portion is upwardly moved to open the low end opening for allowing a ingredient in the chamber to be dropped and mixed with another ingredient contained in the container and to open the opening for allowing the mixture of ingredients to be discharged through the opening.
