Problems solved by technology

[0002] At present, the pressing pumps used in pressing bottles on the market, such as lotion pumps, use traditional coiled metal springs as the return spring of the pump body, but the traditional coiled metal springs tend to tangle together when assembled by an automatic assembly machine, which is inconvenient The efficiency of assembly is not high; 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 push pump contains plastic, metal and other parts, it needs to be disassembled when recycling Sorted recycling is not conducive to the recycling of products

Embodiment 1

[0028] A plastic elastic member such as Figure 1 ~ Figure 3 As shown, it includes a limit connector 1 and several elastic supports 2 arranged at intervals in the circumferential direction on the limit connector 1; the elastic support 2 is arranged obliquely; Elastic deformation can be generated below, so that the position-limiting connecting member 1 can reset and move axially.

[0029] The elastic deformation generated by the inclined elastic support member 2 is bending deformation, which is more durable than the telescopic deformation generated by conventional plastic springs.

[0030] The material of the plastic elastic part is plastic, which is molded by integral injection molding.

[0031] like Figure 1 ~ Figure 3 As shown, the limiting connector 1 includes a connecting ring 11, and a limiting flange 12 circumferentially arranged on the connecting ring 11. Through the connecting ring 11 and the limiting flange 12, the limiting connecting member can 1 The limit is con...

Abstract

The invention discloses a plastic elastic piece, a pressing pump and a pressing bottle. The plastic elastic piece comprises a limiting connecting piece and a plurality of elastic supporting pieces arranged on the limiting connecting piece at intervals in the circumferential direction; the elastic supporting pieces are obliquely arranged; and the elastic supporting pieces can generate elastic deformation under the action of external force, so that the limiting connecting piece reducibly and axially moves. According to the plastic elastic piece, the limiting connecting piece is connected with apressing head in a limiting mode, the phenomenon of shaking left and right cannot occur during pressing, and the phenomenon of head tilt cannot occur due to the fact that the contact area of the plastic elastic piece is large and forcing surfaces of the two ends are planes. In addition, the plastic elastic piece can generate bending deformation, and compared with the telescopic deformation generated by a general plastic spring, the durability is high; and in addition, the plastic elastic piece is integrally a plastic piece, recycling is more facilitated, and the pollution of metal to the environment can be avoided.

Description

technical field [0001] The invention relates to the technical field of cosmetic packaging, in particular to a plastic elastic part, a pressing pump and a pressing bottle. Background technique [0002] At present, the pressing pumps used in pressing bottles on the market, such as lotion pumps, use traditional coil metal springs as the return spring of the pump body, but the traditional coil metal springs are easy to tangle together when assembled by an automatic assembly machine, which is inconvenient Assembly is not efficient; in addition, the traditional coil metal spring assembly pump core is prone to tilting due to uneven ends of the spring; in addition, since the push pump contains plastic, metal and other parts, it needs to be disassembled when recycling Sorted recycling is not conducive to product recycling. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the technical defects of the background technology...
