Description

Technical Field

[0001] The invention relates to the technical field of cosmetic packaging, and in particular to a plastic elastic part, a pressing pump and a pressing bottle. Background Art

[0002] At present, the press pumps used in press bottles on the market, such as lotion pumps, use traditional coil metal springs as the return springs of the pump body. However, traditional coil metal springs are easily tangled together during assembly in automatic assembly machines, which makes assembly inconvenient and inefficient. In addition, the traditional coil metal spring assembly pump core is prone to tilting due to the unevenness of the two ends of the spring. In addition, since the press pump contains plastic, metal and other parts, it needs to be disassembled and sorted for recycling during recycling, which is not conducive to product recycling. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the technical defects of the background technology and provide a plastic elastic part, a pressing pump and a pressing bottle. The plastic elastic part of the present invention is connected to the pressing head through a limiting connector, so there will be no left and right shaking when pressing, and because the contact area of ​​the plastic elastic part is large, the force-bearing surfaces at both ends are flat, so there will be no head tilt phenomenon; in addition, the plastic elastic part of the present invention can produce bending deformation, which is more durable than the telescopic deformation produced by conventional plastic springs; in addition, the plastic elastic part of the present invention is a plastic part as a whole, which is more conducive to recycling and can avoid metal pollution to the environment.

[0011] Furthermore, the elastic supporting members have the same inclination angle.

[0012] Furthermore, the number of the elastic support members is four, and they are arranged at right angles to each other at intervals in the circumferential direction at the bottom of the limiting connection member.

DETAILED DESCRIPTION

[0026] In order to better understand the content of the present invention, further description is given below in conjunction with specific embodiments and accompanying drawings. It should be understood that these embodiments are only used to further illustrate the present invention and are not intended to limit the scope of the present invention.

[0027] Example 1

[0028] A plastic elastic member, such as Figure 1 to Figure 3 As shown, it includes a limiting connection member 1 and a plurality of elastic support members 2 circumferentially spaced apart from the limiting connection member 1; the elastic support members 2 are tilted; the elastic support members 2 can generate elastic deformation under the action of external force, so that the limiting connection member 1 can reset axial movement.

[0029] The elastic deformation produced by the tilted elastic support member 2 is a bending deformation, which is more durable than the telescopic deformation produced by a conventional plastic spring.

[0030] The plastic elastic member is made of plastic and is integrally injection molded.

[0031] like Figure 1 to Figure 3 As shown, the limit connecting member 1 includes a connecting ring 11 and a limit flange 12 circumferentially arranged on the connecting ring 11. Through the connecting ring 11 and the limit flange 12, the limit connecting member 1 can be limit-connected to the force-applying object, and there will be no left and right shaking when pressed.

[0032] like Figure 1 to Figure 3 As shown, the bottom of the elastic support member 2 is in the same horizontal plane; since the force-bearing surfaces of the connecting ring 11 and the bottom of the elastic support member 2 are both flat, the head tilt phenomenon will not occur.

[0033] like Figure 1 to Figure 3 As shown, the elastic support member 2 is a support plate 21; the bottom of the support plate 21 forms an abutment surface 211; the abutment surface 211 is inclined so that the elastic support member 2 and the horizontal plane are connected linearly, which can reduce friction.

[0034] like Figure 1 to Figure 3 As shown, the left and right side surfaces and the upper and lower side surfaces of the abutting surface 211 are all arc-shaped, and the movement trajectory of the bottom of the abutting surface 211 is an arc shape; the angle between the upper and lower side surfaces of the abutting surface 211 and the horizontal plane of the bottom of the abutting surface 211 gradually decreases from the end away from the horizontal plane to the end close to the horizontal plane; through the above arrangement, the plastic elastic member can smoothly perform axial resetting movement.

[0035] like Figure 1 to Figure 3 As shown, the elastic support members 2 have the same inclination angle; there are four elastic support members 2, which are arranged at right angles to each other in the circumferential direction at the bottom of the limit connector 1, so that the plastic elastic member can perform axial reset movement more smoothly.

[0036] like Figure 2 and Figure 3 As shown, a pressing pump comprises a pressing head 3, a pump body assembly 4 which is press-connected to the pressing head 3, and a bottle body connecting seat 5 which is detachably connected to the pump body assembly 4; the pressing head 3 comprises a shell 31, a nozzle 32 arranged inside the shell 31, and a pressing rod 33 which is matched and connected to the nozzle 32; the interior of the pressing rod 33 is hollow; one end of the pressing rod 33 is communicated with the nozzle 32, and the other end is press-connected to the pump body assembly 4; the side wall of the shell 31 forms an outer wall 311; one end of a plastic elastic member as described above is limitedly connected to the outer wall 311, and the other end abuts against the bottle body connecting seat 5.

[0037] The plastic elastic part is arranged between the bottom of the outer wall 311 in the pressing head 3 and the bottle body connecting seat 5, so that there will be no left and right shaking when pressing, and it is convenient to assemble; in addition, since the contact area of ​​the plastic elastic part is increased, and since the force-bearing surfaces at both ends of the plastic elastic part are flat, there will be no head tilting phenomenon.

[0038] like Figure 2 and Figure 3 As shown, the top of the bottle body connecting seat 5 forms a bottle body connecting surface 51 ; the limiting connecting member 1 is interference fit with the bottom of the outer wall 311 ; and the bottom of the elastic supporting member 2 is in contact with the bottle body connecting surface 51 .

[0039] like Figure 2 As shown, the pump assembly 4 is a vacuum pump 41, or Figure 3As shown, the pump body assembly 4 is a non-vacuum pump 42 .

[0040] The vacuum pump 41 and the non-vacuum pump 42 are both conventional technologies.

[0041] like Figure 2 As shown, a pressing bottle comprises a bottle body 6 and a pressing pump as described above which is detachably connected to the bottle body 6.

[0042] like Figure 2 As shown, the pressing bottle is a vacuum bottle; the vacuum bottle includes an outer cover 7; the outer cover 7 covers the side wall of the bottle body connecting seat 5; the internal space of the outer cover 7 can accommodate the pressing head 3; the bottom of the bottle body 6 is provided with a through hole 61; the inside of the bottle body 6 is provided with a large piston 8; when the pressing head 3 is pressed, the vacuum bottle pumps out the liquid inside the bottle body 6 through the pumping action of the vacuum pump 41, and at the same time the large piston 8 moves upward due to the action of the air pressure outside the bottle body 6.

[0043] The above description is not intended to limit the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by a person skilled in the art within the spirit and scope of the present invention shall also fall within the protection scope of the present invention.
