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 pump system, comprising:
a container having a blown-in dip tube;
a valve body connected to the container, comprising:
at least one connector; and
a vent connection;

a piston;
a trigger;
a spring;
a valve;
a blown-in dip tube connector, comprising:
a fluid inlet;
a connector head comprising at least one connector lip;
a fluid flow path between the fluid inlet and the connector head;
a dip tube lock adjacent the fluid inlet;
an o-ring seated in the dip tube lock; and
a vent passage;

wherein the at least one connector lip is snap-fit with the at least one connector of the valve body to retain the blown-in dip tube connector with the valve body and connect the vent passage to the vent connection.

2. The pump system of claim 1 , wherein the trigger and the spring comprise an integrated trigger and spring combination.

3. The pump system of claim 1 , wherein the o-ring seals with the sides of the blown-in dip tube.

4. The pump system of claim 3 , further comprising a product in the container.

5. The pump system of claim 1 , wherein the valve body further comprises a bayonet connection connected to the container.

6. The pump system of claim 1 , further comprising a nozzle in communication with the valve body.

7. The pump system of claim 1 , further comprising a shroud in communication with the valve body.

8. A pump system, comprising:
a container having a blown-in dip tube;
a trigger sprayer having a vent connection extending from an interior portion of a piston chamber to an interior portion of a valve body and connected to the container; and
a blown-in dip tube connector connected to the trigger sprayer, comprising:
a connector head connected to the trigger sprayer;
a fluid inlet;
a fluid flow path between the fluid inlet and the connector head;
an o-ring adjacent the fluid inlet and mated with the blown-in dip tube connector, providing a seal between the o-ring and an interior surface of the blown-in dip tube; and
a vent passage connected to the vent connection.

9. A pump system, comprising:
a container having a blown-in dip tube;
a valve body connected to the container, comprising:
at least one connector; and
a vent connection;

a piston;
a trigger;
a spring;
a valve;
a blown-in dip tube connector, comprising:
a fluid inlet;
a connector head comprising at least one connector lip;
a fluid flow path between the fluid inlet and the connector head; and
a vent passage;

wherein the at least one connector lip is snap-fit with the at least one connector of the valve body to retain the blown-in dip tube connector with the valve body and connect the vent passage to the vent connection.

10. The pump system of claim 9 , further comprising a product in the container.

11. The pump system of claim 9 , wherein the valve body further comprises a bayonet connection connected to the container.

12. The pump system of claim 9 , further comprising a nozzle in communication with the valve body.

13. The pump system of claim 9 , further comprising a shroud in communication with the valve body.

14. A pump system, comprising:
a container having a blown-in dip tube;
a trigger sprayer having a vent connection extending from an interior portion of a piston chamber to an interior portion of a valve body and connected to the container; and
a blown-in dip tube connector connected to the trigger sprayer, comprising:
a connector head connected to the trigger sprayer;
a fluid inlet;
a fluid flow path between the fluid inlet and the connector head; and
a vent passage connected to the vent connection.
