Abstract
A device includes: a base; and an applicator tip, wherein the base and applicator tip are removably connected to each other via a connection, and wherein the device draws and expels a liquid or powder by alternating an increase and decrease of pressure within the device. The device can be used as a nasal aspirator, applicator, or baster for food products. The applicator tip and base can be removably connected to each other via a threaded connection or snap-fit connection. Force applied to the base decreases the volume of the base to create a pressure differential to draw and expel the liquid or powder from the device.
Claims20
A nasal aspirator device comprising:
- a base;
- an applicator tip, wherein the base and applicator tip are removably connected to each other via a second connection, wherein the device draws and expels a liquid or powder by alternating an increase and decrease of pressure within the device,
- wherein the second connection comprises outer threads located at or near a bottom of the applicator tip and inner threads located at or near a top of the base, and wherein the outer threads conjoin with the inner threads to connect the applicator tip to the base,
- wherein the applicator tip further comprises a safety protrusion located near a top of the applicator tip, and wherein the safety protrusion has a fixed larger outer diameter than a portion of the applicator tip located, above the safety protrusion, and wherein the safety protrusion tapers from a larger outer diameter located nearest to the base to a smaller outer diameter located nearest to the top of the applicator tip;
- and
- a cover, wherein the cover is made from a resilient material, wherein the cover encloses a portion of the applicator tip, a portion of the base, and the second connection, wherein the cover comprises sidewalls that form the cover and a cavity within the cover, and wherein the cavity allows the cover to be positioned over the base and the applicator tip, and wherein the cover and applicator tip are removably connected to each other via a first connection.
A nasal aspirator device comprising:
- a base;
- an applicator tip, wherein the base and applicator tip are removably connected to each other via a second connection, wherein the device draws and expels a liquid or powder by alternating an increase and decrease of pressure within the device,
- wherein the second connection comprises a flange located at or near a bottom of the applicator tip and a recess located at or near a top of the base, wherein the flange is circumferentially positioned around and protrudes from sidewalls of the applicator tip, and wherein the recess receives and mates with the flange to connect the applicator tip to the base,
- wherein the applicator tip further comprises a safety protrusion located near a top of the applicator tip, and wherein the safety protrusion has a fixed larger outer diameter than a portion of the applicator tip located above the safety protrusion, and wherein the safety protrusion tapers from a larger outer diameter located nearest to the base to a smaller outer diameter located nearest to the top of the applicator tip;
- and
- a cover, wherein the cover is made from a resilient material, wherein the cover encloses a portion of the applicator tip, a portion of the base, and the second connection, wherein the cover comprises sidewalls that form the cover and a cavity within the cover, and wherein the cavity allows the cover to be positioned over the base and the applicator tip, and wherein the cover and applicator tip are removably connected to each other via a first connection.
