Fluid dispensing device
A fluid delivery device, such as a syringe, is disclosed, including a bellows structure defining a first end, a second end, and a cavity therein, where compressing the bellows structure reduces a height of the syringe; a tip adjacent the first end, the tip defining a channel in fluid communication with the cavity; a post coaxial with the channel and disposed in the cavity adjacent the second end of the bellows structure; a laterally-extending flange adjacent the first end of the bellows structure, the flange defining a width greater than a width of the bellows structure; an adaptor adjacent the tip, the adaptor defining a wall and a threaded interface on an interior surface thereof; and a cap releasably engageable with the tip.
1 . A device for dispensing fluid, comprising:
a bellows structure defining a first end, a second end, and a cavity therein, wherein compressing the bellows structure reduces a height of the device;
a tip adjacent the first end, the tip defining a channel in fluid communication with the cavity;
a flange adjacent the first end, the flange defining a width greater than a width of the bellows structure;
a threaded interface adjacent the tip, the threaded interface including a wall circumscribing the tip, the wall defining a plurality of threads on an interior surface thereof; and
a cap releasably engageable with the tip, the cap defining a protrusion positionable within the channel of the tip and a cap wall having a cylindrical exterior surface releasably engageable with the threaded interface,
wherein the cap is attached to the flange by a living hinge at an outer edge portion of the flange, and
wherein when the protrusion is positioned within the channel of the tip, the cylindrical exterior surface of the cap wall contacts the threads to engage the threaded interface and seal the tip.
2 . The device of claim 1 , wherein the flange includes one or more tactile elements.
3 . The device of claim 1 , further comprising a post disposed in the cavity adjacent the second end of the bellows structure.
4 . The device of claim 3 , wherein the post is at least partially disposed within the channel of the tip when the bellows structure is compressed.
5 . The device of claim 1 , further comprising a base adjacent the second end of the bellows structure, the base having a width greater than the width of the bellows structure.
6 . The device of claim 5 , wherein the base includes a plurality of tactile elements thereon.
7 . A syringe, comprising:
a bellows structure defining a first end, a second end, and a cavity therein, wherein compressing the bellows structure reduces a height of the syringe;
a tip adjacent the first end, the tip defining a channel in fluid communication with the cavity;
a threaded interface adjacent the tip, the threaded interface including a wall circumscribing the tip, the wall defining a plurality of threads on an interior surface thereof;
a post disposed in the cavity adjacent the second end of the bellows structure;
a depressible surface extending laterally from the bellows structure; and
a cap releasably engageable with the tip, the cap defining a protrusion positionable within the channel of the tip and a cap wall having a cylindrical exterior surface releasably engageable with the threaded interface,
wherein the cap is attached to the depressible surface by a living hinge at an outer edge portion of the depressible surface, and
wherein when the protrusion is positioned within the channel of the tip, the cylindrical exterior surface of the cap wall contacts the threads to engage the threaded interface and seal the tip.
8 . The syringe of claim 7 , wherein the depressible surface is positioned adjacent to the first end of the bellows structure.
9 . The syringe of claim 7 , wherein the depressible surface defines a width greater than a width of the bellows structure.
10 . The syringe of claim 7 , wherein the post is at least partially disposed within the channel of the tip when the bellows structure is compressed.
11 . A syringe, comprising:
a bellows structure defining a first end, a second end, and a cavity therein, wherein compressing the bellows structure reduces a height of the syringe;
a tip adjacent the first end, the tip defining a channel in fluid communication with the cavity;
a post coaxial with the channel and disposed in the cavity adjacent the second end of the bellows structure;
a laterally-extending flange adjacent the first end of the bellows structure, the flange defining a width greater than a width of the bellows structure;
an adaptor adjacent the tip, the adaptor defining a threaded interface, the threaded interface including a wall circumscribing the tip, the wall defining a plurality of threads on an interior surface thereof; and
a cap releasably engageable with the tip, the cap defining a protrusion positionable within the channel of the tip and a cap wall having a cylindrical exterior surface releasably engageable with the threaded interface,
wherein the cap is attached to the flange by a living hinge at an outer edge portion of the flange, and
wherein when the protrusion is positioned within the channel of the tip, the cylindrical exterior surface of the cap wall contacts the threads to engage the threaded interface and seal the tip.
