Abstract

The present invention relates to a package for dispensing a liquid product having a blow molded container body including an aperture and a pivotal connection. A pump device is attached to the aperture, and a unitarily formed actuation lever is pivotally connected directly to the pivotal connection of the container body allowing arcuate movement of the actuation lever. The pump device has a first contact surface located on a portion thereof and the actuation lever has a second contact surface which cooperates with the first contact surface enabling the actuation lever to apply a substantially vertical operating force upon the pump device when rotated, thereby dispensing the liquid product. In a preferred embodiment the liquid is dispensed as an atomized spray.

Claims

1. A package for dispensing a liquid product comprising:

(a) a hollow, one-piece integral container body including an upper portion and a closed bottom end, said upper portion including an integral extension and a neck finish, said integral extension extending upward from said upper portion, and said neck finish having an aperture therethrough; and

(b) a pivotal connection on said integral extension, said pivotal connection located above said aperture of said neck finish; and

(c) a pump device attached to said aperture, said pump device having a first contact surface; and

(d) an actuation lever pivotally connected to said container body at said pivotal connection allowing arcuate movement of said actuation lever, said actuation lever having a second contact surface which cooperates with said first contact surface enabling said actuation lever to apply an operating force upon said pump device during said arcuate movement in order to dispense said liquid product.

2. The package for dispensing a liquid product according to claim 1, further comprising a middle portion of said container body located between said closed bottom end and said upper portion, said middle portion including a substantially rigid grip area.

3. The package for dispensing a liquid product according to claim 1, wherein said actuation lever comprises a trigger, unitarily formed of a plastic material.

4. The package for dispensing a liquid product according to claim 1, wherein said container body comprises an integrally molded bottle.

5. The package for dispensing a liquid product according to claim 4, wherein said bottle is blow molded.

6. The package for dispensing a liquid product according to claim 1, wherein said first contact surface further comprises a shoulder and said second contact surface further comprises an alignment lug, said alignment lug cooperating with said shoulder in order to orient said pump device.

7. The package for dispensing a liquid product according to claim 1, wherein said arcuate movement of said actuation lever is in response to the application of a substantially horizontal force upon said actuation lever such that said actuation lever rotates causing said second contact surface to apply a substantially vertical operating force upon said first contact surface, said operating force being about 4 times greater than said substantially horizontal force.

8. The package for dispensing a liquid product according to claim 1, wherein said actuation lever includes a lower end, said lower end of said actuation lever having a contour that conforms to said container body.

9. The package for dispensing a liquid product according to claim 1, wherein said actuation lever includes a trunnion, said pivotal connection and said trunnion cooperating to form a snap fit that allows said trunnion to move relative to said pivotal connection.

10. The package for dispensing a liquid product according to claim 1, wherein said liquid product has a viscosity greater than about 60 cps.

11. The package for dispensing a liquid product according to claim 1, wherein said pump device includes a spray nozzle and said liquid product is dispensed in an atomized spray.

12. The package for dispensing a liquid product according to claim 1, wherein said pivotal connection comprises a separately fabricated component affixed to said integral extension of said upper portion.

13. A package for dispensing a liquid product in an atomized spray comprising:

(a) a one-piece integral blow molded container body that includes a neck furnish having an aperture therein, said container body also including a pivotal connection;

(b) a pump device including a spray nozzle and a closure, said closure engaging said neck finish such that said pump device is attached in fluid communication to said container body through said aperture in said neck finish, said pump device also including a first contact surface located on an upper portion thereof; and

(c) a unitarily formed actuation lever pivotally connected to said container body at said pivotal connection, said pivotal connection allowing arcuate movement of said actuation lever, said actuation lever having a second contact surface which cooperates with said first contact surface during said arcuate movement of said actuation lever in order to apply an operating force upon said pump device and thereby dispensing said liquid product through said spray nozzle in an atomized spray.

14. The package for dispensing a liquid product in an atomized spray according to claim 13, wherein said atomized spray comprises a vegetable oil based cooking spray.

15. The package for dispensing a liquid product in an atomized spray according to claim 13, wherein said actuation lever comprises a trigger unitarily formed of a plastic material that moves in an arcuate manner in response to the application of a substantially horizontal force such that said trigger causes said first contact surface of said pump device to move in a substantially downward direction.

16. The package for dispensing a liquid product in an atomized spray according to claim 15, wherein said operating force is about 4 times larger than said substantially horizontal force.

17. The package for dispensing a liquid product in an atomized spray according to claim 13, wherein said pump device comprises a vertically disposed plunger-type pump device.

18. The package for dispensing a liquid product in an atomized spray according to claim 13, wherein said pivotal connection is located above said neck finish.

19. The package for dispensing a liquid product in an atomized spray according to claim 13, wherein said second contact surface comprises an alignment lug for orienting said pump device.
