DETAILED DESCRIPTION OF THE INVENTION
[32] Referring now to the drawings, an exemplary embodiment of a
dispensing pump system and dispensing pump head in accordance with the teachings of the present invention are illustrated in Figs. 1-13.
[33] Embodiments of the present dispensing pump system 10 and pump head 12 may be advantageously used for various liquids, lotions, etc.
contained within a bottle or other container (not illustrated). In some exemplary embodiments, many of the components of the pump system 10 (with the exception of a metal spring) are molded from the same plastic material making the dispensing pump system 10 easily recyclable in a single plastic material classification.
[34] The dispensing pump system 10 generally includes a dispensing pump head 12 and a pump engine 14. The pump head 12 is removably received in assembled relation with the pump engine 14.
[35] The pump engine 14 includes an accumulator 16 having a dip tube port 18 and a ball valve 20 within the dip tube port 18. The open upper end of the accumulator 16 has an outward flange 22 and an upstanding rim wall 24.
The pump system 10 further includes an annular closure ring 26 engaging the accumulator flange 22 and securing the accumulator 16 to a neck of a container. Some embodiments of the closure ring 26 may be threaded while others may be snap received onto the neck of the container. The pump engine 14 further includes a tubular piston stem 28 coaxially guided within a guide body 30 in the accumulator 16. The piston stem 28 includes a piston seal 32 received about the bottom terminal end thereof that forms a seal with inner walls of the accumulator 16. A compression spring 34 is received around the piston stem 28 and is captured between the bottom wall of the guide body 30 within the accumulator 16 and an annular groove 36 at the upper end of the piston stem 28.
[36] An annular chaplet 38 is coaxially snap received about the rim wall 24 of the accumulator 16. The rim wall 24 and the chaplet 38 include mating snap formations which cooperate to maintain the chaplet 38 in assembled relation with the rim wall 24.
[37] An exemplary dispensing pump head 12 includes main body portion 40, an inlet portion 42 which is removably received onto the piston stem 28 of the pump engine 14, a spout portion 44 with an outlet 46 communicating with the inlet portion 42, and an outer skirt portion 48 extending
downwardly around the inlet portion 42. In the exemplary embodiment, the inlet portion 42 and upper end of the piston stem 28 include friction fit interfitting formations. Other snap or removable fitments are also
contemplated.
[38] In accordance with the invention, the dispensing pump head 12
further includes a removable tamper evident ring 50 which extends downward from the outer skirt 48. The ring 50 is split along a vertical seam forming opposing side edges 52, 54 and includes an outwardly extending pull tab 56 at one of the side edges. Some embodiments may also include a cutaway 58 on the opposing side edge facing the pull tab 56. The upper peripheral edge of the ring 50 and the opposing side edges 52, 54 have
frangible elements or tabs 60 removably securing the opposing edges 52, 54 together and securing the ring 50 to the outer skirt 48.
[39] In some exemplary embodiments, the lower peripheral edge of the tamper ring 50 is seated on the chaplet 38 and prevents the pump head 12 from being depressed during handling and shipment.
[40] Referring to Figs. 6-7, an outward pull on the pull tab 56 will sever the frangible elements 60 between the edges 52, 54 and around the upper edge of the ring wall 50, releasing the ring 50 from the outer skirt 48 and allowing the ring 50 to be removed (See Fig. 7) for use.
[41] Turning now to Figs. 14-16, in some exemplary embodiments 100, the tamper evident ring 150 includes an angled cut 158 in one of the side edges 152, 154 which allows the user to pry the ring 150 away from the outer skirt 148 of the pump head 112.
[42] In other exemplary embodiments 200, as illustrated in Figs. 17-21, the outer skirt 248 and tamper ring 250 on the pump head 212 are larger in diameter and the lower peripheral edge of the ring 250 is seated directly on the closure ring 226 outside the chaplet. Some embodiments in this configuration may include a pull tab (not shown) and cut out or an angled cutout 258 as described above.
[43] It may also be possible in some embodiments that the pump head 12 and tamper ring 50 are configured so that the lower peripheral edge of the ring 50 is seated on an exterior surface of the bottle or container (not shown).
[44] In operation of the pump systems, a forcible downward compression of the pump head causes a corresponding downward axial movement of the piston stem and compression of the spring. Upon the subsequent release of the dispensing head, the spring expands back to its normal at rest shape causing a forcible upward movement of the piston stem and dispensing head back to their normal at rest positions.
[45] As noted above, exemplary pump configurations 10, 100, 200 are
shipped without a box and with the pump head and piston stem in the
extended position and it is thus important to prevent accidental depression of the pump head during shipping. Shipping with the pump head exposed in the extended position also subjects the assembly to possible damage from impacts during handling. The present dispensing configurations and tamper evident ring prevent actuation of the pump head during shipment and protects the piston stem, pump head and chaplet from impact related damage. The removable tamper ring also provides tamper evidence once received by the consumer.
[46] It can therefore be seen that the exemplary embodiments provide unique and novel dispensing pump assemblies which better protect the assembly during shipment.
[47] While there is shown and described herein certain specific structures embodying various embodiments of the invention, it will be manifest to those skilled in the art that various modifications and rearrangements of the parts may be made without departing from the spirit and scope of the underlying inventive concept and that the same is not limited to the particular forms herein shown and described except insofar as indicated by the scope of the appended claims.
