Applicator for a dispensing appliance
View Patent ↗The applicator for a double cartridge includes an adapter for connection to a mixer attached to a double cartridge as well as a dispensing slot, the side of the enclosure that is turned towards the glued substrate forming an angle with the longitudinal axis of the adapter which is comprised between 5° and 90°. The underside of the enclosure is essentially continuously curved. Due to the curvature of the enclosure, the material that is to be glued, e.g. lung tissue, is first smoothened and immediately thereafter evenly coated with adhesive. This allows a reliable application of such an applicator in medicine or in the industry.
1. An applicator for dispensing material from a dispensing appliance or a mixer onto a substrate for a medicinal technique, comprising:
an enclosure having a lower portion configured to face toward the substrate and an opposing upper portion;
an adapter having a longitudinal axis and configured to connect to the mixer or dispensing appliance;
a dispensing slot defined by respective terminal end portions of the upper portion and the lower portion of the enclosure where the upper and lower portions converge at a tip at a dispensing end of the enclosure, wherein the dispensing slot is located off the longitudinal axis of the adapter;
wherein the lower portion of the enclosure has an essentially continuous curvature at a first radius adapted to smooth the substrate to which the material is to be applied, and forms an angle with the longitudinal axis of the adapter, and
wherein the upper portion has an essentially continuous curvature at a second radius.
2. The applicator of claim 1 , wherein the angle is between 5° and 90°.
3. The applicator of claim 1 , wherein said enclosure is conically enlarged towards the dispensing slot.
4. The applicator of claim 1 , wherein the lower portion has an inner surface including a plurality of guiding walls, wherein the plurality of guiding walls forms a plurality of channels in the enclosure which lead to the dispensing slot.
5. The applicator of claim 1 , wherein the terminal end portion of the upper portion is longer than the terminal end portion of the lower portion.
6. The applicator of claim 5 , wherein the end portion of the upper portion is about 0.5 mm longer than the end portion of the lower portion.
7. The applicator of claim 1 , wherein the dispensing end has one of a straight, concave, or convex shape.
8. The applicator of claim 1 , wherein the dispensing slot has a cross-section that has one of a rectangular, angled, entirely-arc, or oval shape.
9. The applicator of claim 1 , wherein the applicator is configured to dispense onto a tissue.
10. The applicator of claim 9 , wherein the tissue has an uneven surface.
11. The applicator of claim 1 , wherein the applicator is configured to dispense an adhesive.
12. The applicator of claim 1 , wherein the applicator is configured to dispense a sealant.
13. The applicator of claim 1 , wherein the slot has a width between 12 and 16 mm and a thickness of between 0.1 and 0.3 mm.
