Detailed Description

The preferred embodiments of the present invention will hereinafter be described in conjunction with the appended drawings, where like designations denote like elements throughout.

Fig. 1 and 2 show a push pump 1 according to a preferred embodiment of the present invention. As shown in the figure, the pressing pump 1 comprises a pressing head 2, a tooth socket 3, a cylinder cover 4, a piston assembly 5, a cylinder 6, a gasket 7, a return spring 8, a one-way valve 9, a connecting conduit 10, a suction pipe 11 and the like. It should be understood that the pressing pump 1 is merely exemplary, and the pressing pump of the present invention may include other components than those described above, or may omit some of the above components, or may replace or change some of the components.

The basic operation principle of the feed liquid suction by the pressing pump 1 is similar to that of the prior art. In short, when the pressure head 2 is pressed down, the feed liquid in the pressure pump 1 is pumped out. When the pressure head 2 moves upwards due to the action of the return spring 8, the liquid in the bottle is sucked into the pump cavity through the suction pipe 11.

The head 2 is configured to expel the feed liquid from the mouthpiece outlet upon depression by a user. The ram 2 is connected to a first end of a connecting duct 10, the second end of which is connected to a piston assembly 5 described in detail below.

Mouthpiece 3 serves to close feed liquid bottle opening 100, in other words, to connect push pump 1 to bottle opening 100. In particular, the mouthpiece 3 engages the mouth of the bottle by means of a coupling structure (in this embodiment an internal thread, but also non-helical reliefs or other coupling structures such as coupling teeth) and ensures sealing with the mouth of the bottle by means of a gasket 7 provided at the top of the mouthpiece.

The cylinder head 4 is used to close the cylinder 6. Specifically, the cylinder head 4 is connected to the upper end of the cylinder 6, for example, by a screw structure. In this embodiment, the cylinder head 4 is a separate component, but it should be understood that the cylinder head 4 may also be formed integrally with the socket 3.

The piston assembly 5 is configured to reciprocate within a cylinder 6. The piston assembly 5 is connected to the connecting duct 10 so as to move downwards when the ram 2 is pressed and upwards under the action of the return spring 8. The piston assembly 5 includes a piston 51 and a piston head (or rod) 52. The piston 51 is slidably fitted over the piston head 52. When the piston head 52 is forced to move in the cylinder 6, the piston 51 can move up and down relative to the piston head 52. The piston 51 preferably cooperates with a piston stop on the cylinder head 4 to prevent further upward travel of the piston 51.

The inner wall of the cylinder 6 is in contact engagement with the piston 51. A check valve 9 is arranged in the cylinder 6. A return spring 8 is also provided in the cylinder 6 and acts on the piston head 52. The suction pipe 11 is provided at a lower end portion of the cylinder 6 and is communicated with the bottom of the bottle body (not shown).

The utility model is mainly characterized in that an anti-theft device is arranged on the tooth socket 3, and the anti-theft device can display whether the pressing pump 1 is illegally opened.

Specifically, as shown in figures 3-5 and 7-10, mouthpiece 3 includes a mouthpiece body 31 and a tear ring 32, which are interconnected by one or more frangible connections 33. The mouthpiece body 31, the tearing ring 32 and the at least one tearable connector 33 are integrally connected by molding. The tear ring 32, the at least one frangible connection 33, and the associated structure on the mouthpiece body 31 constitute the previously described "anti-theft device".

As is clear from fig. 7 to 10, two projections 311 are provided at the lower portion of the mouthpiece body 31, and two recesses 321 are provided at corresponding positions of the tearing ring 32. The protrusion 311 on the mouthpiece body 31 and the recess 321 on the tearing ring 32 have substantially corresponding shapes, i.e., one side of the protrusion 311 and the recess 321 is arranged as a straight surface, and the other side is arranged as a slant surface or an arc surface. As described in more detail below, the protrusion 311 and the recess 321 cooperate with each other. It will be appreciated that whilst in this embodiment the lugs are provided on the mouthpiece body and the corresponding recesses are provided on the tear ring, it is also possible to provide the lugs on the tear ring and the corresponding recesses on the mouthpiece body in reverse.

When the mouthpiece 3 is rotated clockwise, for example, to screw the pressing pump 1 on the bottle mouth 100, the straight surface on the side of the protrusion 311 pushes the corresponding straight surface of the recess 321, and the mouthpiece body 31 drives the tear-off ring 32 to rotate synchronously until the tear-off ring 32 passes over the snap ring 101 of the bottle mouth, thereby completing the installation of the pressing pump 1. When the pump 1 is pressed to be unscrewed by, for example, rotating the mouthpiece 3 counterclockwise, the slope of the other side of the projection 311 pushes the corresponding slope of the recess 321. In this case, the mouthpiece body 31 and the tear ring 32 are more easily moved relatively, thereby generating a separating force of the mouthpiece body 31 and the tear ring 32. Under the force of this separation, the frangible connection 33 is broken. Thus, the tear ring 32 can be retained on the mouth 100 and the mouthpiece body 31 can be further unscrewed from the mouth 100. In other words, the mouthpiece body 31 and the tear ring 32 are separated. And this separation is irreversible.

Preferably, the tearable connector 33 is configured to be small at the top and large at the bottom, i.e., the upper portion has a smaller cross section and the lower portion has a larger cross section. Therefore, when the tear line 33 is broken, it is easier to break the tear line from the smaller cross section, so that the tear line 33 can be left on the tear ring 32 instead of the mouthpiece body 31. Leaving the frangible connection 33 on the tear ring 32 is easier to handle and does not injure the hand.

Because of the anti-theft device, the utility model discloses a press pump has the effect that the trace was stayed in the kaifeng. That is, when the consumer purchases the product, the mouthpiece body 31 and the tear ring 32 are no longer integral but separate as long as the consumer sees that the frangible connection 33 on the pump mouthpiece is broken, indicating that the product has been opened illegally before. The opened product has no guarantee on the safety aspect and is not suitable for purchase. Conversely, if the peel connector 33 is not broken, the consumer may be assured of purchasing it.

While the present invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various equivalent changes and modifications may be made on the basis of the foregoing disclosure, e.g., other constructions of the pump may be varied other than the anti-tamper device on the mouthpiece, e.g., a one-piece piston (rather than a "piston assembly"), connecting conduits, return springs, etc. may be omitted; as another example, the shape and configuration of the tear ring can be varied as desired, as can the number of frangible connections and projections and recesses. Accordingly, the scope of the present invention should not be limited by the foregoing description, but should be defined by the appended claims.
