Abstract

A pump system may include a blown-in dip tube connected to a valve body and having a connection which may include an improved blown-in dip tube connector having one or more of a lip for sealing with a blown-in dip tube, a seal ring configured to mate with a blown-in dip tube and seal therewith, a dip tube lock for mating with a blown-in dip tube, or an o-ring for providing an improved seal with a blown-in dip tube.

First claim

What is claimed is:

1. A blown-in dip tube connector for connecting a blown-in dip tube of a container with a fluid passageway of a trigger sprayer, said blown-in dip tube connector comprising:
a fluid inlet, a fluid outlet, and a fluid flow path between the fluid inlet and fluid outlet;
a connector head about the fluid outlet;
a fluid chamber within the connector head in communication with the fluid outlet;
at least one connector lip about a periphery of the connector head;
at least one seal on an exterior surface of the fluid inlet end wherein the at least one seal is frustoconical in shape;
said blown-in dip tube connector being formed from a polymer material;
said at least one seal being formed from an elastomeric material selected from the group consisting of a thermoplastic elastomer, a thermoplastic urethane, a thermoplastic polyurethane and silicone; and
wherein the at least one connector lip retains the blown-in dip tube connector with the trigger sprayer and the at least one seal seals with the blown-in dip tube of the container.

2. The blown-in dip tube connector of claim 1 wherein:
said fluid inlet has a first diameter which is smaller than a diameter of said fluid flow path.

3. The blown-in dip tube connector of claim 1 wherein:
said at least one seal has a seal lip which has a diameter which is larger than said diameter of said flow path.

4. The blown-in dip tube connector of claim 2 wherein:
said at least one seal has a seal lip which has a diameter which is larger than said diameter of said flow path.
