Bandage composition dispenser
Provided is a bandage composition dispenser and/or applicator that includes a nozzle and a cap. In some embodiments, the dispenser and/or applicator is used to dispense a bandage or dressing composition that forms a durable film bandage or skin protectant.
1. A dispenser, comprising:
a container containing a bandage or dressing composition;
a dispensing nozzle having a shape and size and including a nozzle head that connects or mates with the container and a preformed slot for dispensing the bandage or dressing composition, wherein the dispensing nozzle is part of the container and/or capable of attachment to the container and further wherein the dispensing nozzle has an outer nozzle cavity extending between the nozzle head and the preformed slot, the outer nozzle cavity having two opposing straight sides and two opposing curvilinear sides; and
a removable cap configured to connect with one of the container and/or the nozzle, wherein the removable cap includes an interior region having a size and shape configured to match the size and shape of the dispensing nozzle and connecting with the container and/or the dispensing nozzle by a screw fit mechanism, wherein the removable cap is self-aligning when the removable cap is twisted to a position where a top of the removable cap is properly seated over the preformed slot;
wherein, when the cap is connected with the container or nozzle, the preformed slot of the dispensing nozzle mates with and/or nests within a preformed recess including a conformable material that forms an abutment surface that sealingly engages the preformed slot;
wherein the cap further comprises:
a nonconformable portion made of a less conformable material than the conformable material, and the less conformable material has a Shore A hardness of at least 1.2 times the Shore A hardness of the conformable material
and wherein a top portion of the cap is substantially free of the less conformable material.
2. The dispenser of claim 1 , wherein the bandage or dressing composition has a viscosity greater than 20,000 Centipoise (cps) when measured at 23° C. using a Brookfield LVT viscometer.
3. The dispenser of claim 1 , wherein the slot has an area of between about 0.001 in 2 to about 1 in 2 .
4. The dispenser of claim 1 , wherein the dispensing nozzle has a ratio of a width of bandage or dressing composition entry cavity to slot width upper maximum of about 1:1.
5. The dispenser of claim 1 , wherein the dispensing nozzle has a volume of between about 0.00824 in 3 and about 0.038 in 3 .
6. The dispenser of claim 1 , further including a tapping area.
7. The dispenser of claim 1 , wherein the preformed recess has an area of between about 0.0015 in 2 to about 2 in 2 .
8. The dispenser of claim 1 , wherein the conformable material has a hardness of between about 30 shore A and about 70 shore A as measured by ASTM D2240-15 Standard Test Method for Rubber Property—Durometer Hardness.
9. The dispenser of claim 1 , wherein the bandage composition when applied using the dispenser has a wet coat weight of 50 to 120 mils at a generally uniform thickness.
10. The dispenser of claim 1 , wherein the bandage composition, when applied and dried, has a thickness of between about 1 mil and about 10 mils.
11. The dispenser of claim 1 , wherein the dispensing nozzle is tapered from the slot to a nozzle head or container and the degree of draft is between about 2 degrees and about 10 degrees.
12. The dispenser of claim 1 , wherein the two opposing curvilinear sides are convex.
13. The dispenser of claim 1 , wherein the two opposing curvilinear sides are concave.
14. A dispenser, comprising:
a container containing a bandage or dressing composition;
a dispensing nozzle including a nozzle head that connects or mates with the container and a slot for dispensing the bandage or dressing composition, wherein the dispensing nozzle is part of the container and/or capable of attachment to the container and further wherein the dispensing nozzle has an outer nozzle cavity extending between the nozzle head and the preformed slot, the outer nozzle cavity having two opposing straight sides and two opposing curvilinear sides; and
a removable cap configured to connect with one of the container and/or the nozzle, wherein the removable cap includes an interior region having a size and shape configured to match the size and shape of the dispensing nozzle and connecting with the container and/or the dispensing nozzle by a screw fit mechanism, wherein the removable cap is self-aligning when the removable cap is twisted to a position where a top of the removable cap is properly seated over the preformed slot,
wherein, when the removable cap is connected with the container or nozzle, the slot of the dispensing nozzle sealingly engages a portion of the removable cap; and
wherein the removable cap includes a first material having a Shore A hardness of between about 30 and about 70 and a second material having a Shore A hardness of at least 1.2 times the Shore A hardness of the first material, and wherein a top portion of the cap is substantially free of the second material.
15. The dispenser of claim 14 , wherein the slot sealingly engages a portion of the removable cap by mating with and/or nesting within a preformed recess in the removable cap that forms an abutment surface that forms the seal between the slot and the removable cap.
16. The dispenser of claim 14 , wherein the bandage or dressing composition has a viscosity of greater than 20,000 Centipoise (cps) when measured at 23?C using a Brookfield LVT viscometer.
17. The dispenser of claim 14 , wherein the slot has an area of between about 0.001 in 2 to about 1 in 2 .
18. The dispenser of claim 14 , wherein the dispensing nozzle has a ratio of a width of bandage or dressing composition entry cavity to slot width with an upper maximum of about 1:1.
19. The dispenser of claim 14 , wherein the dispensing nozzle has a volume of between about 0.00824 in 3 and about 0.038 in 3 .
20. The dispenser of claim 14 , wherein the first material has a hardness of between about 20 Shore A and about 70 Shore A as measured by ASTM D2240-15 Standard Test Method for Rubber Property—Durometer Hardness.
21. The dispenser of claim 14 , wherein the two opposing curvilinear sides are convex.
22. The dispenser of claim 14 , wherein the two opposing curvilinear sides are concave.
