Patent Application
20130236640
1. Field
The present invention relates to an applicator for applying resin adhesive to a crease in fabric or clothing such as trousers or shirts to ensure a permanent crease. In particular, the present invention provides for an improved applicator applying resin adhesive to a crease in fabric or clothing a guide which is located behind a receiver head where the receiver head is attached to the rear end of the cartridge and a threadably attached nozzle located at the distal front end of the cartridge.
2. The Related Prior Art
U.S. Pat. No. 6,722,537 discloses a cartridge for dispensing fluent materials into creases of garments where the cartridge includes a plastic elongated body having an integral tongue projecting laterally of the body at one end and through which the fluent composition (40) is dispensed by passing a piston (32) along the inside of the body. The tongue is a narrow member and is aligned with integral laterally projecting fins (18, 20) which fit into the crease of a garment to be rendered permanent. The tongue has a narrow rectangular bore into which fits a nozzle also having a narrow rectangular bore. The tongue bore and the nozzle bore are aligned with the fins so as to provide maximum exactness in alignment of the body, crease and ribbon of composition which is dispensed from the nozzle.
U.S. Pat. No. 6,422,777 shows an applicator gun for resins for crack repair; Spatula 24 (e.g., an aluminum blade) extends from the top end 26 of nozzle 14 and functions to spread the protective coating once it is urged through the end opening of nozzle 14 by the action of plunger 28,
U.S. Pat. No. 4,756,170 discloses a crease-setting composition which comprises an applicator body having at one end thereof a nozzle; air is compressed by a compressor 7 and sent through a filter and regulator 8, to bear against a piston 10 in the applicator 4; the composition in the cylinder is acted on by the piston and forced through the nozzle 5. A fin-like guide plate 11 is mounted on the lower surface of the applicator body 4. The width 12 of the plate 11 at its lower edge corresponds to the crease to be set in the fabric.
The present invention relates to an improved applicator for applying resin to a crease in clothing. The improved applicator includes a piston driven cartridge filled with resin/adhesive preferably silicon and has a guide located behind a receiver head that is attached, preferably clipped onto the rear end of the cartridge 5. The applicant is the inventor of two earlier patents U.S. Pat. No. 5,211,755 granted May 18, 1993 and U.S. Pat. No. 6,363,634 granted Apr. 2, 2002 and incorporates the subject matter thereof by reference thereto as if included herein.
The present invention further includes the receiver head connected to a hose to provide pneumatic pressure to push along the piston in the cartridge to dispense the resin out of the front distal end of the tube so that an operator can provide adequate pressure on the front distal end when the nozzle is attached on the cartridge to ensure that the resin is firmly applied within the creases of the garment.
In addition, the guide provides for a small, inexpensive piece of equipment for providing an efficient and cost effective technique solution for guiding the resin in the creases of garments.
Still another object of the present invention is to provide a threadably connectable nozzle to the distal front end of the cartridge where the nozzle has a flat dispensing end for the dispensing resin in the crease. The flat shape of the nozzle is smaller than the dispenser of the cartridge in order to achieve a better fluid flow when a fluid/resin is dispensed.
It is still another object of the invention to provide an o-ring between the joinder of the cartridge and nozzle to prevent resin from escaping and air from entering.
Other objects of the present invention will become apparent from the foregoing description and accompanying drawings.
Referring now to the drawings of
The present invention shown in
Behind the receiver head 11 is removably connected a guide 7 that can be seated in a crease of a textile article such as an article of clothing so that it guides the applicator 1 along the longitudinal length of the crease as the adhesive resin 6 is supplied from the slit 12 in the flat end 13 of the nozzle 10. The guide 7 moves within the crease to ensure that the resin 6 is distributed and applied accurately in the crease. Having the guide 7 located behind the cartridge 5 and the receiver head 11 makes it easier to guide the applicator 1 while maintaining the necessary pressure for the nozzle 10 to remain firmly in the crease. The applicator 1 moves along within the crease dispensing the resin 6. The guide can be reused with different cartridges 5 and can be firmly attached to the receiver head 11 with a screw or by other known connecting mechanisms. The guide (
At the distal front end 9 of the tube 5 is a preferably threadably connectable nozzle 10 which connects to the threads of the cartridge 5. The nozzle 10 has a flat dispensing end 13 with a slit 12 through which is dispensed resin 6 into the crease. The flat dispensing end 13 has a flat shape to better align itself with the crease (see
While presently preferred embodiments have been described for purposes of the disclosure, numerous changes in the arrangement of method steps and apparatus parts can be made by those skilled in the art. Such changes are encompassed within the spirit of the invention as defined by the appended claims.
