Abstract

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

a cap body comprising a mouth and an inner housing formed with a chamber, a lower end opening and an upper opening;

a working member adapted to be assembled to the cap body, the working member comprising;

an upper end portion in sealing contact with the upper opening when the working member is in an initial position;

an extended part having a lower end, the extended part extending through the chamber of the inner housing such that the ingredient in the cap assembly is contained between the inner housing and the extended part; and

a lower sealing portion provided at the lower end of the extended part to seal the lower end opening when the working member is in the initial position; and

when the working member with the extended part is upwardly moved from the initial position, the lower sealing portion is moved out of sealing contact with the lower end opening to drop an ingredient in the chamber into the container so as to be mixed with an another ingredient accommodated in the container to form a mixture and the upper end portion is moved out of sealing contact with the upper opening so that the mixture may be discharged through the upper opening.

2. 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.

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

4. 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.

5. The cap assembly in accordance with claim 1 wherein the working member further comprises an opening above the upper end portion such that the mixture may be discharged between the working member and the upper opening of the inner housing and then through the opening in the working member when the working member is upwardly moved from the initial position.

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

a cap body comprising a mouth and an inner housing formed with a chamber, a lower end opening and an upper opening;

a working member adapted to be assembled to the cap body, the working member comprising;

an upper end portion in sealing contact with the upper opening when the working member is in an initial position;

an extended part having a lower end, the extended part extending through the chamber of the inner housing such that the ingredient in the cap assembly is contained between the inner housing and the extended part;

a lower sealing portion provided at the lower end of the extended part to seal the lower end opening when the working member is in the initial position; and

an opening above the upper end portion;

such that when the working member with the extended part is upwardly moved from the initial position, the lower sealing portion is moved out of sealing contact with the lower end opening and the upper end portion is moved out of sealing contact with the upper opening so that a mixture may be discharged to the opening in the working member from between the working member and the upper opening and then through the opening in the working member.

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

a cap body comprising a mouth and an inner housing formed with a chamber, a lower end opening and an upper opening;

a working member adapted to be assembled to the cap body, the working member comprising;

an upper end portion in sealing contact with the upper opening when the working member is in an initial position;

an extended part having a lower end, the extended part extending through the chamber of the inner housing such that the ingredient in the cap assembly is contained between the inner housing and the extended part; and

a lower sealing portion provided at the lower end of the extended part to seal the lower end opening when the working member is in the initial position;

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 by a separate closing member; and

when the working member with the extended part is upwardly moved from the initial position, the lower sealing portion is moved out of sealing contact with the lower end opening to drop an ingredient in the chamber into the container so as to be mixed with an another ingredient accommodated in the container to form a mixture and the upper end portion is moved out of sealing contact with the upper opening so that the mixture may be discharged through the upper opening.
