Description

A kind of high leakproofness screw thread glass bottle

Technical field

The utility model relates to a kind of medicine, chemical industry packaging high leakproofness mold of thread mouth glass bottle.

Background technology

At medical treatment and chemical industry packaging field, due to glass bottle stable performance, store effective, glass bottle is commonly used to all kinds of vaccine of splendid attire, powder-injection, liquid drugs injection and all kinds of chemical reagent; And this kind of mold of thread mouth glass bottle is owing to only adopting outside thread as Hermetical connecting structure, but external thread structure requires higher to the making of bottle cap supporting with it, and sealing property is also difficult to ensure.Now in order to the sealing property of reinforcing glass bottleneck, provide a kind of new technical scheme.

Utility model content

The purpose of this utility model is the deficiency overcoming above background technology, provides a kind of novel glass bottle hermetically-sealed construction, and this structure has that leak tightness is strong, structure is simple, simultaneously can reinforcing glass bottle to the protectiveness of packing material.

The purpose of this utility model can be achieved through the following technical solutions:

A kind of high leakproofness screw thread glass bottle, comprise bottle, bottle upper end is connected with bottleneck by bottleneck, and the bottleneck outer wall of described bottleneck is shaped with forward screw thread, and bottleneck inwall is smooth, cylindrical peripheral surface; The bottleneck inwall of described bottleneck is the conical surface; Be provided with bottle closure of rubber in described bottleneck, the bottle stopper bottom of bottle closure of rubber is the conical surface, and bottle stopper top is the face of cylinder, coordinates with bottleneck inwall.

Described bottleneck upper inside wall diameter is greater than lower diameter.

The beneficial effects of the utility model: the bottleneck inwall in the utility model is the conical surface, uses cone rubber bottle stopper during sealing; The forward screw thread of bottleneck outer wall uses the negative thread bottle cap of coupling, and under the extruding of the screw threads for fastening power of negative thread bottle cap and forward screw thread, it is more fastening that bottle closure of rubber can coordinate with conical surface bottleneck, improves further using conical suface as the sealing effectiveness of sealing surface; Circular hole area in addition due to base of neck is little compared with bottleneck, and when using the bottle closure of rubber of taper, bottle closure of rubber reduces with the packing material area of contact in bottle, and reduction bottle closure of rubber is on the impact of packing material physicochemical property.

Accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Fig. 1 is the structural representation of the utility model embodiment;

Sequence number in figure: 1-bottle, 2-bottleneck inwall, 3-forward screw thread, 4-bottleneck inwall, 5-bottleneck anchor ring, 6-bottleneck outer wall, 7-bottle closure of rubber, 8-bottle stopper top, 9-bottle stopper bottom.

Detailed description of the invention

In embodiment shown in Fig. 1, a kind of high leakproofness screw thread glass bottle, comprises the glass bottle bottle 1 of an intersegmental part cavity, can hold packing material as container; Bottle 1 upper end is connected with bottleneck by bottleneck, bottleneck outer wall 6 is shaped with forward screw thread 3, accordingly, has negative thread bottle cap (not marking in figure) to match with bottleneck outer wall 6; Bottleneck inwall 4 is smooth, cylindrical peripheral surface; Bottleneck inwall 2 is in the conical surface, and bottleneck inwall 2 is that upper diameter is large, lower diameter is little; The transition junction bottle thickness of bottleneck and bottle is thicker (the bottle thickness of 1.5-2 times), makes that the intensity of glass bottle is high, strong shock resistance.

Bottleneck inwall 4 is the face of cylinder, and bottleneck inwall 2 is the conical surface, accordingly, has bottle closure of rubber 7 to coordinate with it, and bottle stopper bottom 9 sidewall of bottle closure of rubber 7 is similarly the conical surface, coordinates with bottleneck inwall 2.Bottle stopper top 8 is the face of cylinder, coordinates with bottleneck inwall 4, like this under the fastening force of negative thread bottle cap and forward screw thread 3, applies towards the thrust at the bottom of bottle, the conical surface of bottle closure of rubber 7 and bottleneck inwall 2 are fitted closely, realizes sealing effectiveness bottle closure of rubber 7; With traditional glass bottle using bottleneck anchor ring 5 as sealing surface compared with, the contact seal area of conical suface is large, and conical surface sealing structure this is just effective than face seal, by the way, realize higher sealing property; In addition because the lower end of bottle closure of rubber 7 is cone structure, the area ratio bottleneck area of going to the bottom of bottle closure of rubber is little, when during such sealing, the contact area rate simple glass bottle of bottle closure of rubber and packing material seals, the area of bottle closure of rubber contact packing thing is little, significantly can reduce the impact of bottle closure of rubber on packing material physicochemical property, improve packing material storge quality.

Above content is only to the utility model structure example and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of utility model or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
