Abstract

The utility model discloses a medical liquid medicine bottle, comprising a bottle cap and a bottle. A ring-shaped anti-groove is molded in the cap and forms an interference fit with the opening of the bottle; a cuneate covex table is also molded on the inner wall of the bottle cap; a cone-shaped flange is molded on the outer wall of the opening of the bottle; the cone-shaped flange and the cuneate covex table form a unidirectional fastening fit. The structure has the advantages of low production cost, convenient use, good sealing effect, etc., and is particularly suitable for the production and the packing of the oral liquid and the sunction liquid medicine.

Description

A kind of medical medicinal liquid bottle

Technical field

This utility model relates to the Sealed packing bottle in the field of liquid packaging bottle, particularly medical medicinal liquid.

Background technology

Medical medicinal liquid bottle is higher to the seal request of bottle, bottle cap, the at present modal structure that packs adopts rubber stopper or plastic plug shutoff bottleneck, and then be aided with aluminum matter cover cap, such hermetically-sealed construction production cost is higher, and seal-packed technology is complicated, the troublesome poeration of uncapping during use, adopt easy-to-draw limit structure, directly adopt intubate that aluminum matter cover cap is worn out, but use all very inconveniently, bottle cap is difficult to open or wear out.

The utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, proposes that a kind of production cost is low, easy to use, the medical medicinal liquid bottle of good sealing effect.

The technical solution of the utility model is: a kind of medical medicinal liquid bottle, include bottle cap and bottle, bottle cap inside forms the annular hole groove with the bottle body and bottleneck interference fit, also form the wedge shape convex on the inwall of bottle cap, and the outer wall of bottle body and bottleneck forms the taper bead, and taper bead and wedge shape convex form unidirectional being clasped.Further, insert use for ease of suction pipe, there is thin-walled depression in the central authorities of bottle cap, and the wall thickness of depression is 0.06-0.2mm.

Such design has tangible advantage:

1, bottle cap, bottle can adopt polyethylene, the one-shot forming of polyester material, need not use aluminum matter cover cap, and production cost is low, make simple;

2, the mutual buckle of bottle cap and bottle, good sealing effect, bottle cap are not easy to be opened, and meet medical requirement;

3, concavity holds easy inserting, is convenient to suction pipe and inserts use, uses, operates very easy.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the local enlarged diagram of bottle cap, bottle.

The specific embodiment

Referring to Fig. 1, Fig. 2, present embodiment includes bottle cap 1 and bottle 2, and wherein bottle cap 1 adopts polythene material, bottle 2 to adopt the polyester forming materials.Particularly part is that the inside of bottle cap 1 forms annular hole groove 11, and the width of annular hole groove 11 is slightly less than the bottleneck wall thickness of bottle 2, and bottleneck 21 forms interference fit with annular hole groove 11, thereby makes bottle cap 1 with bottleneck 21 sealings.For making bottle cap 1 and bottleneck 21 mutual lockings, the inwall middle part of bottle cap 1 forms wedge shape convex 12, the top of wedge shape convex 12 is that right angle step T, bottom are lozenges A, the outer wall middle part of face bottleneck 21 also forms taper bead 22, when bottle cap 1 cover is pressed on the bottleneck 21, taper bead 22 forms unidirectional being clasped with wedge shape convex 12, taper bead 22 slips into wedge shape convex 12 right angle step T places, make bottle cap 1 and bottleneck 21 mutual lockings, can't oppositely get loose, unless destroy bottle cap 1, otherwise can't throw off bottle cap 1.And, forming thin-walled depression 13 at the central part of bottle cap 1, the wall thickness of depression 13 only be 0.1mm, by mould one drawing and forming when bottle cap 1 molding, is convenient to gently expose brokenly with plastic suction pipe the convenient clothes bottle inner liquid medicine of inhaling like this.

Certainly, only enumerated a kind of preferred implementation here, the protection domain that other are equal to, structure roughly the same all should belong to this patent repeats no more here.

Claims (2)

1, a kind of medical medicinal liquid bottle, include bottle cap and bottle, it is characterized in that: bottle cap inside forms the annular hole groove with the bottle body and bottleneck interference fit, also form the wedge shape convex on the inwall of bottle cap, and the outer wall of bottle body and bottleneck forms the taper bead, and taper bead and wedge shape convex form unidirectional being clasped.

2, medical medicinal liquid bottle according to claim 1 is characterized in that there is thin-walled depression in the central authorities of bottle cap, and the wall thickness of depression is 0.06-0.2mm.
