CN201542940U - Novel medicinal bottle plug inner pad - Google Patents

Abstract

The utility model discloses a novel medicinal bottle plug inner pad, wherein the top surface and bottom surface of the inner pad are both provided with round flutes, the round flutes and a pad body form a concentric circle structure, the pad body is hermetically buckled between a plastic outer cover and a plastic inner cover through the flutes, and the top surface of the pad body is a range delimited by the flutes are provided with at least three round pits which are same in size and mutually and externally tangent. The top surface and bottom surface of the inner pad body are provided with up-and-down corresponding round pits which are needling portions, thereby leading the thickness of the needling portions of the pad to get quite thin, enabling the weight of a rubber plug to be decreased by about 15 percent and reducing the manufacturing cost; on the other hand, needle point portions are liable to drop into the positions of the pits when needling, thereby avoiding the phenomenon of shred falling when needling; thirdly, the needling portions are thinner than peripheral portions, when needling, the stress is concentrated towards the center direction, thus the phenomenon of needle sliding can not appear, and the self density of needle holes are much stronger.

Description

A kind of novel medicinal bottle stopper internal gasket

Technical field:

This utility model relates to a kind of novel medicinal bottle stopper internal gasket, belongs to technical field of medicine packaging.

Background technology:

The existing injection bottle stopper structure of bottle, a kind of is the flange formula structure that is made of flange and plug neck, and this structure is eliminated at present substantially, and few people use; Another kind is the bottle closure of rubber assembly that is made of pad and other working of plasticss, the surface of the pad of this bottle stopper is provided with the protruding circle of elasticity, be provided with 2 recessed circles of little elasticity and a big slightly recessed circle in the protruding circle, the position of this three recessed circle during for ease of contact pin, it is thin slightly that other position thickness are compared in this position.But there is such drawback in the pad of this structure, and three recessed circle areas are too little, and the user is accustomed to contact pin at random in use, final contact pin position greatly may be outside three recessed circles, and the acupuncture position is too thick, easily causes the phenomenon of acupuncture exfoliation, after pin is extracted, pin hole neither be fine from close property.

Summary of the invention:

For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of novel medicinal bottle stopper internal gasket, adopt the synthetic polyisoprenes material to make, in the protruding circle of the elasticity of gasket surface, rationally be distributed with at least three recessed circles, help improving the contact pin position and be in the interior accuracy rate of recessed circle, avoid acupuncture exfoliation phenomenon, and save the material of making pad.

This utility model technical solution problem adopts following technical scheme:

A kind of novel medicinal bottle stopper internal gasket, the end face of described internal gasket and bottom surface all offer the circular groove that constitutes concentric structure with shim body, shim body is fastened between plastic outer cover and the plastics inner cap hermetically with described groove, and the end face of the shim body in described groove institute delineation scope is provided with at least three equal sizes and circumscribed circular pit mutually.

Construction features of the present utility model also is:

The bottom surface of described shim body also is provided with the corresponding circular pit of each pit with end face.

The medial wall of described each circular pit is a ramp structure, and promptly the internal diameter of pit oral area is greater than the internal diameter of pit bottom.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

The end face of this utility model internal gasket body and bottom surface are provided with corresponding up and down circular pit, and pit is the acupuncture position, so is arranged so that the greatly attenuation of thickness at pad acupuncture position, and can make plug weight reduce about 15%, have reduced manufacturing cost; On the other hand, the needle tip position falls into groove position easily during acupuncture, avoids acupuncture exfoliation phenomenon; The 3rd, the position of acupuncture than around thin, when acupuncture, stress is concentrated to center position, thereby can not produce sliding pin phenomenon, pin hole also stronger from close property.

Description of drawings:

Fig. 1 is a structural representation of the present utility model; Fig. 2 is the A-A cutaway view of Fig. 1.

Number in the figure: 1 groove, 2 shim body, 3 pits.

Below pass through the specific embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.

The specific embodiment, non-limiting examples is as described below:

Embodiment: in conjunction with Fig. 1,2 present embodiment medicinal bottle stopper internal gaskets, adopt the synthetic polyisoprenes material to make, the end face of internal gasket and bottom surface all offer the circular groove 1 that constitutes concentric structure with shim body, shim body 2 is fastened on respectively between plastic outer cover and the plastics inner cap with two grooves 1 up and down, between plastic outer cover and inner cap, form sealing, the plastics inner cap is installed on the oral area of infusion bottle hermetically, end face in the shim body groove scope is exposed to the external world, during transfusion, needle point punctures shim body earlier and punctures in the through medicinal liquid of plastics inner cap again, for ease of acupuncture and avoid the pad exfoliation, should make the acupuncture position be thinner than shim body, therefore the end face of the shim body of this utility model pad in 1 delineation scope of groove is provided with at least three equal sizes and mutual circumscribed circular pit 3, in conjunction with Fig. 2, for reaching optimum efficiency, the bottom surface of shim body also is provided with the corresponding circular pit of each pit with end face.As shown in Figure 1, three pit inner rings all basic and groove form inscribe, that is to say, in the scope of groove delineation, make three pit maximizations as much as possible, so the purpose that is provided with is: 1, pit is convenient to acupuncture greatly, avoids exfoliation, and the acupuncture position of pit bottom is the thinnest, when acupuncture, stress is concentrated to center position, thereby can not produce sliding pin phenomenon, pin hole also stronger from close property.2, when the acupuncture position of three pits was thin as much as possible, the used material (imported material, costliness) of solid shim minimized, and saves cost.3, make the thinnest acupuncture position with the form of three pits, do not reduce the bearing capacity of shim body, can not break because of pressure causes pad.

The medial wall of each circular pit is a ramp structure as shown in Figure 2, be the internal diameter of the internal diameter of pit oral area greater than pit bottom, so the purpose that is provided with is, before pad formation finished product is delivered for use, need cleaning and sterilizing, the pit medial wall is designed to ramp structure, and being convenient to pit bottom is the cleaning and sterilizing at acupuncture position, can not produce to clean the dead angle.

Claims (3)

1. novel medicinal bottle stopper internal gasket, the end face of described internal gasket and bottom surface all offer the circular groove that constitutes concentric structure with shim body, shim body is fastened between plastic outer cover and the plastics inner cap hermetically with described groove, it is characterized in that the end face of the shim body in described groove institute delineation scope is provided with at least three equal sizes and circumscribed circular pit mutually.

2. novel medicinal bottle stopper internal gasket according to claim 1 is characterized in that, the bottom surface of described shim body also is provided with the corresponding circular pit of each pit with end face.
