## Abstract

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

## Claims

### Claim 1

A pump system, comprising:
a container, comprising:
a blown-in dip tube; and
a blown-in dip tube seat;
a trigger sprayer connected to the container; and
a blown-in dip tube connector fluidly connecting the container to the trigger sprayer, comprising:
a fluid inlet;
at least one seal ring adjacent the fluid inlet, said at least one seal ring seated in the blown-in dip tube seat of the container;
a connector head attached to the trigger sprayer;
a fluid flow path between the fluid inlet and the connector head; and
a vent passage.

### Claim 2 (depends on 1)

The pump system of claim 1, wherein the trigger sprayer further comprises a valve body.

### Claim 3 (depends on 2)

The pump system of claim 2, wherein the valve body further comprises:
a connector; and
a vent connection.

### Claim 4 (depends on 2)

The pump system of claim 2, wherein the valve body further comprises a connector, wherein the connector is connected to the connector head of the blown-in dip tube connector.

### Claim 5 (depends on 2)

The pump system of claim 2, wherein the valve body further comprises a vent connection, wherein the vent connection is connected to the vent passage of the blown-in dip tube connector.

### Claim 6 (depends on 1)

The pump system of claim 1, wherein the trigger sprayer further comprises:
a valve body, comprising:
a piston chamber; and
a vent connection;
a piston seated in the piston chamber;
a trigger attached to the piston;
a spring biasing the trigger;
a shroud covering at least a portion of the valve body; and
a nozzle.

### Claim 7 (depends on 1)

The pump system of claim 1, further comprising a fluid contained within the container.

### Claim 8 (depends on 6)

The pump system of claim 6, further comprising a fluid contained within the container.

### Claim 9 (depends on 8)

The pump system of claim 8, wherein actuation of the trigger of the trigger sprayer sprays the fluid from the nozzle and de-actuation draws fluid from the container through the blown-in dip tube, through the fluid flow path of the blown-in dip tube connector, and into the piston chamber of the trigger sprayer.
