Abstract
This invention relates to a pouch injector made from a flexible and/or collapsible material. The pouch could contain a gusset that allows the pouch to free stand and allows for a greater pouch interior volume. The pouch and dispensing adapter(s) are used to dispense and/or inject a liquid, for example, into a tire through the valve stem. The invention can be used for either repairing a tire puncture and also preventing future tire punctures and leaks
Claims14
A pouch for applying a liquid, comprising:
- a collapsible and flexible pouch housing for containing an amount of fluid;
- an opening defined in the pouch;
- an adapter in fluid communication with the pouch opening for applying fluid from the pouch to a desired location.
A tire sealant injector for injecting sealant into a tire, the tire sealant injector comprising:
- a sealant reservoir having a chamber for receiving tire sealant, said chamber having an inside and an outside surface, said chamber having an axial length;
- a tubing connector positioned at one end of said chamber;
- a length of tubing having a first and second end, said first end being attached to said tubing connector;
- a valve stem connector having a length, said valve stem connector having an internal bore through said length, said internal bore having a first set of female threads and a second set of female threads located within said internal bore, said first set of threads being Schrader threads and said second set of threads being Presta threads;
- wherein said reservoir is formed by a flexible, collapsible bag so that the entire contents of the reservoir can be expelled from the reservoir in one continuous compression of the flexible, collapsible bag regardless of the amount of fluid in the reservoir;
- whereby tire sealant is dispensed through said tubing connector, tubing and valve stem connector into a tire through a valve stem by compressing said bag.
A fluid injector for injecting fluid into an opening, the fluid injector comprising:
- a fluid reservoir having a chamber for receiving fluid, said chamber having an inside and an outside surface, said chamber inside surface defining an interior space;
- a length of tubing having a first and second end, said first end being in fluid communication with the interior space of said chamber;
- a tubing connector for connecting said tube to a valve stem of one selected from the group of a tire and a tube;
- wherein said reservoir is formed by a flexible, collapsible pouch so that the entire contents of the reservoir can be expelled from the reservoir in one continuous compression of the flexible, collapsible pouch regardless of the amount of fluid in the reservoir;
- whereby tire sealant is dispensed through said tubing connector, tubing and valve stem connector into a tire through a valve stem by compressing said flexible, collapsible pouch.
