Abstract

A dispensing capsule has an upper cap having a concave depression and a lower cap. The lower cap defines an internal chamber adapted to contain a first ingredient and has an upper flexible seal, a lower sealing member, and a plunger disposed in the internal chamber, whereby the plunger is engaged with the upper flexible seal. The flexible seal may be a blast or flexible bellow. The upper cap is threadingly engaged with the lower cap and lower cap adapted to threadingly engage a container, such as a bottle, IV bag, or the like. Twisting the upper cap with respect to the lower cap causes the concave depression to apply downward force to the upper flexible seal, causing the plunger to displace downward and break the lower sealing member, dispensing said first ingredient from the internal chamber into the container below.

Claims

1. A dispensing capsule, comprising:

an upper cap having a concave depression;

a lower cap defining an internal chamber adapted to contain a first ingredient and having an upper flexible seal comprising a stepped bellow, a lower sealing member, and a plunger having a forked distal end disposed in said internal chamber, said plunger engaged with said upper flexible seal;

said upper cap threadingly engaged with said lower cap;

said lower cap adapted to threadingly engage a container;

wherein twisting said upper cap with respect to said lower cap causes said concave depression to apply downward force to said upper flexible seal, causing said plunger to displace downward such that said forked distal end breaks said lower sealing member, dispensing said first ingredient from said internal chamber and;

wherein a lower portion of said upper cap includes one or more circumferentially disposed cut-outs, said cut-outs configured to lockingly engage one or more protrusions on the inside of an outer race of said lower cap when said upper cap is entirely completely onto said lower cap.

2. The dispensing capsule of claim 1, wherein said internal chamber is adapted to contain a solid, a liquid, a gas, or combinations thereof.

3. The dispensing capsule of claim 1, wherein said first ingredient is adapted to mix with a second ingredient contained in said container.

4. The dispensing capsule of claim 1, further comprising a cover covering said upper cap.
