Abstract
The present invention provides a device, a system, and a method for application of fluids.
Claims64
An applicator device for applying a fluid, comprising:
- a handle having a proximal end and a distal end, the handle comprising:
- a receptacle at the proximal end of the handle, the receptacle configured to receive a packet containing a fluid and facilitate expulsion of the fluid from the packet;
- and
- a flexible lid configured to sealingly enclose the packet within the receptacle and configured to deflect in response to application of exterior pressure enabling application of the exterior pressure to the packet when disposed within the receptacle to thereby compress the packet to release the fluid from the packet;
- a base at the distal end of the handle and configured to direct flow of the released fluid and including a distal opening;
- and
- an applicator pad coupled to the base, in fluid communication with an interior portion of the receptacle, wherein a portion of the pad is inserted within the distal opening of the base, and a portion of the pad is wrapped around an exterior portion of the distal opening of the base.
4 more elements
An applicator device for applying a fluid, comprising:
- a handle having a proximal end and a distal end, the handle comprising:
- a receptacle at the proximal end of the handle, the receptacle configured to receive a packet containing a fluid and facilitate expulsion of the fluid from the packet, the applicator device including at least one venting feature configured to allow air flow into or out of the receptacle;
- and
- a flexible lid configured to sealingly enclose the packet within the receptacle and configured to deflect in response to application of exterior pressure, enabling application of the exterior pressure to the packet when disposed within the receptacle to thereby compress the packet to release the fluid from the packet;
- a base at the distal end of the handle and configured to direct flow of the released fluid and including a distal opening;
- and
- an applicator pad configured to be coupled to the base, in fluid communication with an interior portion of the receptacle via the distal opening of the base.
4 more elements
A system for applying a fluid, comprising:
- a packet containing a fluid, the packet comprising:
- first and second opposing packet sides defining therebetween a sealed space containing the fluid;
- a frangible area configured to rupture upon compressing the packet to release the fluid from the packet;
- and
- a collapsibility feature enabling the first packet side of the packet to invert from a convex position to a concave position upon compressing the packet so that the formerly sealed space is substantially completely collapsed;
- and
- an applicator device comprising:
- a handle having a proximal end and a distal end, the handle comprising a receptacle at the proximal end of the handle, the receptacle configured to receive the packet of the fluid and facilitate expulsion of the fluid from the packet;
- a base disposed at the distal end of the handle and configured to direct flow of the released fluid and including a distal opening;
- and
- an applicator pad configured to be coupled to the base, in fluid communication with an interior portion of the receptacle via the distal opening of the base.
8 more elements
A method for applying a fluid to a surface, comprising:
- applying pressure to a flexible outer surface of a handle at a proximal end of an applicator device to thereby exert pressure on a fluid-filled packet disposed within the handle to compress a flexible portion of the packet, causing a frangible area of the packet to rupture to release the fluid from the packet;
- allowing the fluid to flow through the handle through a distal opening in a base at a distal end of the applicator device to an applicator pad attached to the base, the applicator pad being inserted within the distal opening in the base and wrapped around an outer portion of the distal opening of the base;
- and
- contacting the applicator pad of the applicator device to a surface to transfer the fluid from the applicator pad to the surface.
1 more element
A method of attaching an applicator pad to a base of an applicator device, comprising:
- holding a handle of the applicator device in a fixture with a base of the applicator device facing up;
- placing the applicator pad on top of the base;
- bringing an ultrasonic horn of an ultrasonic welding apparatus down over both the applicator pad and the base to thereby create an welds the surface of applicator pad to an edge of the base.
