Description

Technical Field

[0001] This invention relates to the field of packaging, and in particular to a pump and a pump nozzle rotary telescopic packaging. Background Technology

[0002] Chinese invention patent CN207684093U discloses a rotary telescopic vacuum bottle, comprising a bottle body, an inner liner installed inside the bottle body, a piston installed inside the inner liner, a screw cap installed on the inner liner, a press pump installed on the screw cap, and the press pump and screw cap having eccentric circular cross-sections. An inner press head is installed on the press pump, and an inner cover is installed on the screw cap. An outer cover is fitted onto the inner cover, and an outer press head is installed on the top of the outer cover. The outer cover drives the inner cover to rotate, simultaneously driving the inner press head to rotate relative to the press pump, thereby achieving telescopic extension and retraction of the inner press head relative to the opening on the outer cover.

[0003] The problem with the existing technology is that although the inner pump can rotate and extend, it is still in contact with the outside atmosphere after it retracts into the outer cover. Therefore, the emulsion in the inner pump can still solidify or oxidize. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the purpose of this invention is to provide a rotary telescopic packaging for a pump and pump nozzle, which has the advantage of good sealing performance when closed.

[0005] The technical solution adopted by this invention to solve the problem is:

[0006] A pump includes a pump core, the pump core including an inner pusher with a pusher channel inside, and a middle cover, an inner cover, a pump nozzle, and a hollow ball shaft; the pump core is mounted on the inner cover, the middle cover is sleeved outside the inner cover, the middle cover is rotatable relative to the inner cover by a certain angle, the middle cover has a middle outlet, the hollow ball shaft is rotatably mounted on the outlet end of the inner pusher, and the inner end of the pump nozzle is fixedly connected to and communicates with the hollow ball shaft;

[0007] When the middle cover is not rotated relative to the inner cover, the pump is in the open state. At this time, the outer end of the pump nozzle extends out of the middle outlet, and the hollow ball shaft is connected to the push-head channel.

[0008] When the middle cover rotates at a certain angle relative to the inner cover, the outer end of the pump nozzle is pushed by the middle cover, causing the pump nozzle and the hollow ball shaft to rotate together. The outer end of the pump nozzle retracts into the middle outlet, the hollow ball shaft is disconnected from the push-button channel, and the pump is in the off state.

[0009] As a further preferred technical solution, the middle cover is provided with a second limiting groove, and the inner cover is provided with an inner limiting protrusion. The inner limiting protrusion extends into the limiting groove and can rotate in the limiting groove. The second limiting groove is provided with a third stop point and a fourth stop point. When the inner limiting protrusion rotates, it can be engaged with the third stop point or the fourth stop point.

[0010] As a further preferred technical solution, it also includes an outer cover, which is fitted over the middle cover and has an outer outlet. The outer cover can rotate at a certain angle relative to the middle cover. When the pump is in the open state, the outer outlet is connected to the middle outlet, and when the pump is in the closed state, the outer outlet is offset from the middle outlet.

[0011] As a further preferred technical solution, the outer cover is provided with an outer limiting groove, the outer limiting groove is provided with an outer stopping point, and the middle cover is provided with a first stopping point and a second stopping point. When the outer stopping point rotates, it can be engaged with the first stopping point or the second stopping point.

[0012] As a further preferred technical solution, a baffle is provided on the front or rear side of the outlet, and when the pump is in the closed state, the pump nozzle abuts against the baffle.

[0013] As a further preferred technical solution, the inner cover is provided with an outward-facing clearance groove, the rear end of the clearance groove is connected to the massage head channel, the hollow ball shaft is located at the connection between the clearance groove and the massage head channel, and the clearance groove and the massage head channel are perpendicular to each other.

[0014] The present invention also provides a pump nozzle rotary telescopic packaging, including the pump, and a bottle body, the inner cover being fixedly installed on the top of the bottle body, the pump core being installed on the inner cover, the lower end of the pump core extending into the bottle body; and a cap, the top of the middle cover having an opening, the cap being disposed in the opening, and the cap being connected to the top of the inner nozzle.

[0015] The beneficial effects of this invention are: in the closed state, the pump nozzle retracts into the middle cover, which serves as a dustproof function; the hollow ball shaft closes the push-button channel, isolating the contents of the push-button channel from air and preventing solidification or oxidation.

[0028] Reference Figures 1 to 3 as well as Figure 7 A pump includes: a pump core 8, the pump core 8 including an inner pusher 4, the inner pusher 4 having a pusher channel 41, and also including a middle cover 6, an inner cover 7, a pump nozzle 2, and a hollow ball shaft 3;

[0029] The pump core 8 is mounted on the inner cover 7, the middle cover 6 is sleeved on the inner cover 7, the middle cover 6 can rotate relative to the inner cover 7 at a certain angle, the middle cover 6 is provided with a middle outlet 60, the hollow ball shaft 3 is rotatably mounted on the outlet end of the inner nozzle 4, and the inner end of the pump nozzle 2 is fixedly connected to and communicates with the hollow ball shaft 3.

[0030] When the middle cover 6 is not rotated relative to the inner cover 7, the pump is in the open state. At this time, the outer end of the pump nozzle 2 extends out of the middle outlet 60, and the hollow ball shaft 3 is connected to the push head channel 41.

[0031] When the middle cover 6 rotates at a certain angle relative to the inner cover 7, the outer end of the pump nozzle 2 is pushed by the middle cover 6, causing the pump nozzle 2 and the hollow ball shaft 3 to rotate together. The outer end of the pump nozzle 2 retracts into the middle outlet 60, the hollow ball shaft 3 is disconnected from the push-button channel 41, and the pump is in the off state.

[0032] As a further improved embodiment, the middle cover 6 is provided with a second limiting groove 66, and the inner cover 7 is provided with an inner limiting protrusion 71. The inner limiting protrusion 71 extends into the limiting groove and can rotate in the limiting groove. The middle cover 6 restricts the inner limiting protrusion 71 in the second limiting groove 66, which is one of the implementation methods to realize the relative rotation of the middle cover 6 and the inner cover 7 within a certain angle range.

[0033] The second limiting groove 66 is provided with a third stop point 63 and a fourth stop point 64. When the inner limiting protrusion 71 rotates, it can engage with the third stop point 63 or the fourth stop point 64. The third stop point 63 and the fourth stop point 64 cooperate with the inner limiting protrusion 71 to temporarily lock the relative position of the middle cover 6 and the inner cover 7.

[0034] As a further improved embodiment, an outer cover 5 is also included, which is fitted over the middle cover 6. The outer cover 5 has an external outlet 50 and can rotate relative to the middle cover 6 at a certain angle. When the pump is in the open state, the external outlet 50 is connected to the middle outlet 60; when the pump is in the closed state, the external outlet 50 is offset from the middle outlet 60. The outer cover 5 is mainly used to cover the middle outlet 60 when the pump is closed, serving as a dustproof function and improving the overall aesthetics of the packaging.

[0035] As a further improved embodiment, the outer cover 5 is provided with an outer limiting groove 51, and the outer limiting groove 51 is provided with an outer stop point 52. The middle cover 6 is provided with a first stop point 61 and a second stop point 62. When the outer stop point 52 rotates, it can engage with the first stop point 61 or the second stop point 62. The engagement of the outer stop point 52 with the first stop point 61 or the second stop point 62 is used to temporarily lock the relative position between the outer cover 5 and the middle cover 6.

[0036] In a preferred embodiment, a baffle 65 is provided on the front or rear side of the outlet 60. When the pump is in the off state, the pump nozzle 2 abuts against the baffle 65. The baffle 65 is used to increase the contact area between the cover 6 and the pump nozzle 2, thereby improving the stability of the cover 6 driving the pump nozzle 2 to rotate.

[0037] In a preferred embodiment, the inner cover 7 is provided with an outwardly opening clearance groove 42. The rear end of the clearance groove 42 communicates with the push-button channel 41. The hollow ball shaft 3 is located at the connection between the clearance groove 42 and the push-button channel 41. The clearance groove 42 and the push-button channel 41 are perpendicular to each other. The clearance groove 42 is used to avoid the pump nozzle 2.

[0038] Operating principle:

[0039] Taking counterclockwise rotation as the direction to open the pump nozzle as an example, the outer cover 5 is rotated counterclockwise, and the outer cover 5 rotates relative to the middle cover 6. The outer stop point 52 is disconnected from the first stop point 61. The outer stop point 52 is rotated to connect with the second stop point (62). The outer outlet 50 is rotated to align with the middle outlet 60. The outer cover 5 pushes the middle cover 6 to rotate together. The third stop point 63 is disconnected from the inner limit protrusion 71. The middle cover 6 rotates relative to the inner cover 7. The pump nozzle 2 and the hollow ball shaft 3 are reset as the middle cover 6 rotates. The fourth stop point 64 is rotated to connect with the inner limit protrusion 71. The outer end of the pump nozzle 2 extends out of the outer outlet 50. The hollow ball shaft 3 is connected to the push head channel 41.

[0040] When the pump nozzle is closed, rotate the outer cover 5 clockwise. The fourth stop point 64 disengages from the inner limit protrusion 71. The outer cover 5 and the middle cover 6 rotate together. The pump nozzle 2 and the hollow ball shaft 3 are pushed to rotate by the middle cover 6. The third stop point 63 rotates to connect with the inner limit protrusion 71. The middle cover 6 stops rotating. The second stop point (62) disengages from the outer stop point 52. The outer cover 5 rotates alone. The outer stop point 52 rotates to connect with the first stop point 61. The outer cover 5 is relatively fixed by the middle cover 6. The hollow ball shaft 3 is disconnected from the push-button channel 41, and the pump nozzle 2 retracts into the middle outlet 60. The outer outlet 50 covers the middle outlet 60, providing good dust protection. The overall design is simple and clear, making it easy for consumers to carry and put in their bags without damaging the product or soiling the bag.

[0041] Reference Figures 4 to 6 A pump-nozzle rotary telescopic packaging includes the aforementioned pump, a bottle body 9, an inner cap 7 fixedly mounted on the top of the bottle body 9, a pump core 8 mounted on the inner cap 7, and the lower end of the pump core 8 extending into the bottle body 9; it also includes a cap 1, the top of a middle cap 6 having an opening, the cap 1 being disposed in the opening, and the cap 1 being connected to the top of an inner push-button 4. When the pump is open, pressing the cap 1 drives the pump core 8 to pump the contents of the bottle body 9 out. The pump core 8 can be a pump core from the prior art, which will not be described in detail here.
