Abstract
An applicator tip (10) for applying fluid to the surface of an object is disclosed. The applicator tip (10) has a base (13) formed of thermoplastic material having a first surface and a second surface. At least one aperture (25) extends through the base. A fluid supply port (29) is operatively connected to the second surface of the base and is in communication with at least one aperture in the base. A fluid application material (35) is positioned on the first surface of the base. The fluid application material is positioned to receive fluid that passes through the aperture from the fluid supply port. The fluid application material is secured to the first surface of the base by a portion of the base that is caused to be molten and fuses to the fluid application material.
Claims35
An applicator tip for applying fluid to a surface of an object comprising:
- a base formed of a thermoplastic material having a substantially planar upper first surface and an opposing lower second surface;
- at least one aperture extending through said base;
- a fluid supply port operatively connected to said second surface of said base, said supply port being in communication with said at least one aperture in said base;
- a fluid application material positioned on said first surface of said base, said fluid application material being positioned to receive fluid that passes through said aperture from said fluid supply port, said fluid application material being positioned to apply said fluid to said surface on said object, a first portion of said fluid application material being secured to a first portion of said first surface of said base, which first portion of said base is caused to be molten or semimolten and fuses to said first portion of said fluid application material;
- and
- a second portion of said fluid application material and a second portion of said first planar surface of said base forming a fluid passage space for receiving said fluid wherein pressure from said fluid in said space causes said second portion of said fluid application material to move away from said second portion of said base such that said fluid flows through said space and substantially saturates said fluid application material.
An applicator tip for applying fluid to an object comprising:
- a base having at least one aperture extending through said base for connection to a supply of fluid;
- a cavity having at least one sidewall positioned on said base, said sidewall being made of a heat flowable plastic material;
- and
- a fluid application material positioned in said cavity, said fluid application material being secured to said cavity by a first portion of said sidewall that is caused to be flowable and fuses with a first portion of said fluid application material whereby said fluid application material is bonded to said cavity.
A method for forming an applicator tip for applying fluid to a surface of an object comprising:
- applying heat adjacent a first portion of a base formed of a thermoplastic material to cause said first portion to become molten or semimolten;
- adhering a fluid application material to said molten or semimolten first portion of said base whereby said molten or semimolten thermoplastic material fuses with at least a first portion of said fluid application material;
- and,
- forming a fluid passage space between a second portion of said fluid application material and a second portion of said base for receiving said fluid wherein pressure from said fluid in said space causes said second portion of said fluid application material to move away from said second portion of said base such that said fluid flows through said space and substantially saturates said fluid application material.
