Abstract

The present invention is directed to a closure system for an oral active agent delivery device. The device comprises an elongate tubular member having first and second ends. The closure system includes a deformable closure means adapted to allow delivery of the active agent upon deformation. The closure system prevents spillage and maintains the integrity of the dose within the device. In use, the closure system is deformed and separated from the second end of the tubular member, liquid is drawn up into the first end of the member, and the liquid and active agent are drawn out of the second end of the member and into the patient'"'"'s mouth.

Claims

1. A tubular device, comprising:

a first tubular member having a first end suitable for placement in a liquid and a second end suitable for placement in the mouth of a patient;

a deformable closure means disposed in said first tubular member, said deformable closure means comprising a second tubular member, said second tubular member comprising an inner portion and an outer portion, wherein said outer portion is received within said second end of said first tubular member, said second tubular member comprising an inner portion and an outer portion, said inner portion comprising a cutting edge and said outer portion comprising a frangible membrane.

2. The tubular device of claim 1, further comprising:

a detent disposed on said inner portion; and

a corresponding detent disposed on said outer portion.

3. The tubular device of claim 1, further comprising:

discrete units comprising an active agent disposed in said first tubular member.

4. The tubular device of claim 3, wherein said discrete units are selected from the group consisting of particulates, oral dosage forms and combinations thereof.

5. The tubular device of claim 3, wherein said discrete units provide for prolonged delivery of said active agent.

6. The tubular device of claim 3, wherein said discrete units provide for immediate delivery of said active agent.

7. The tubular device of claim 3, wherein said discrete units provide for delayed pulsed delivery of said active agent.

8. The tubular device of claim 3, wherein said discrete units comprise a therapeutically effective amount of said active agent.

9. The tubular device of claim 8, wherein said therapeutically effective amount is between 100 and 5000 mg.

10. The tubular device of claim 3, wherein said active agent is selected from the group consisting of antibiotics, antiviral agents, anepileptics, analgesics, anti-inflammatory agents, and bronchodilators.

11. A closure system for opening a closed tubular device containing a substance for oral administration, comprising:

a tubular member; and

a deformable closure means disposed in said tubular member, said deformable closure means comprising an inner portion and an outer portion, said inner portion comprising a cutting edge and said outer portion comprising a frangible membrane.

12. The closure system of claim 11, further comprising:

a detent disposed on said inner portion.

13. The closure system of claim 12, further comprising:

a corresponding detent disposed on said outer portion.

14. The closure system of claim 11, wherein said inner portion further comprises:

a blunt edge.
