Description

A kind of glass bottle bottle closure of rubber

Technical field

The utility model relates to a kind of medical package utensil, specifically a kind of packaging glass bottle bottle closure of rubber.

Background technology

In medical package field, glass bottle is commonly used to all kinds of vaccine of splendid attire, powder-injection, liquid drugs injection, and be all that hollow parts is towards in bottle to the medical grade rubber bottle stopper of glass bottle sealing, and rely on the contact compressing rubber plug and bottleneck to seal, this bottle stopper sealing means is single, and material contained in rubber during medicament long-time storage is larger on the impact of medicament physicochemical property.

Utility model content

The purpose of this utility model is the deficiency overcoming above background technology, provides a kind of glass bottle bottle closure of rubber of new structure, and this structure has that leak tightness is strong, structure is simple, significantly can reduce the impact of elastomeric material on packing material physicochemical property simultaneously.

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

A kind of glass bottle bottle closure of rubber, this bottle stopper is made up of rubber cylinder and ring surface, and described rubber cylinder top is provided with cavity; The bottle stopper outer wall of described rubber cylinder is provided with upper and lower twice circular groove, forms rubber ring between twice circular groove.

Described rubber cylinder upper end circumference stretches out formation ring surface.

The height of distance bottle stopper bottom surface, described cavity bottom surface is less than the height of upper and lower twice annular slot pitch from bottle stopper bottom surface.

Described circular groove cross section is " E " shape.

The beneficial effects of the utility model: the utility model utilizes cavity to communicate with ambient atmosphere, twice circular groove on rubber cylinder is tightly fitted bottleneck inwall under ambient pressure, play first hermetically-sealed construction, under the thrust of aluminium lid, form second hermetically-sealed construction by ring surface and bottleneck ring surface, enhance the sealing property of bottle closure of rubber to glass bottle; During this outer gland sealing, the area of contact of the utility model bottle stopper bottom surface and packing material, much smaller than the area of contact of ordinary bottle plug and packing material, reduces the material of bottle closure of rubber own to the impact of packing material physicochemical property, the holding time of the prolong drug property of medicine.

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;

Fig. 2 is the structural representation of traditional stopper;

Sequence number in figure: 1-ring surface, 2-circular groove, 3-rubber ring, 4-bottle stopper outer wall, 5-bottle stopper bottom surface, 6-cavity, 7-bottle stopper, 8-rubber cylinder, the common anchor ring of 1a-, the common outer wall of 4a-, the common bottom surface of 5a-, at the bottom of the common chamber of 5b-, 5c-common chamber wall, 7a-ordinary bottle plug.

Detailed description of the invention

In embodiment as shown in Figure 1, glass bottle bottle closure of rubber, comprise " recessed " shape bottle stopper 7, the cavity 6 of bottle stopper 7 is on bottle stopper top, and accent is upward; The rubber cylinder 8 that glass bottle opening filled in by bottle stopper 7 is provided with upper and lower twice circular groove 2, one rubber ring 3 is formed between twice circular groove 2, and twice circular groove 2 is under the atmospheric effect in the external world, form a kind of similar sucker structure, be adsorbed on glass bottle bottleneck inwall; The bottom surface of cavity 6 is lower than the circular groove of below in twice circular groove 2, and namely the height of cavity 6 bottom surface distance bottle stopper bottom surface 5 is less than the height of upper and lower twice circular groove 2 apart from bottle stopper bottom surface 5, and circular groove 2 cross section is " E " shape.

When bottle stopper 7 seals corresponding glass bottle, in glass bottle, be in vacuum state; Bottle stopper outer wall 4 and bottleneck contact internal walls are fitted, the vallecular cavity that now circular groove 2 and glass bottle are formed is vacuum chamber, because cavity 6 and ambient atmosphere are come round, by the effect of external atmosphere pressure, bar pressure, vallecular cavity, bottle stopper, bottleneck inwall form the structure of a similar vacuum cup, thus twice circular groove 2 and rubber ring 3 are by bar pressure being pressed on bottleneck inwall tightly, form a kind of hermetically-sealed construction.

Further, the rubber cylinder 8 upper end circumference of bottle stopper 7 stretches out and forms ring surface 1, and ring surface 1, under the thrust of aluminum bottle cover, with the ring surface close contact of glass bottle bottleneck, forms the second face seal structure; Through above-mentioned two seals structure, significantly strengthen the utility model bottle closure of rubber to the sealing property of glass bottle.

In addition during the utility model bottle stopper 7 sealed glass jars, bottle stopper outer wall 4 and bottleneck contact internal walls are fitted, and thus only have bottle stopper bottom surface 5 to contact with the packing material in glass bottle; And during ordinary bottle plug 7a seal glass, as shown in Figure 2, after being compressed by common anchor ring 1a, common outer wall 4a and bottleneck inwall are fitted, and common bottom surface 5a, common housing 5b, common chamber wall 5c may contact with the packing material of glass bottle; Both compare, when the utility model bottle stopper 7 seals and the area of contact of packing material much smaller than the area of contact of ordinary bottle plug 7a and packing material, therefore can the material of remarkable low bottle closure of rubber own on the impact of packing material physicochemical property, the holding time of the prolong drug property of medicine.

Because bottle stopper of the present utility model is when realizing sealed glass jars, cavity communicates with ambient atmosphere, and the cavity that twice annular groove is formed is vacuum state, under external atmosphere pressure effect, on rubber cylinder 8, twice circular groove 2 and glass bottle bottleneck inwall form twice vacuum cup groove, tightly fit under ambient pressure, first hermetically-sealed construction is played with bottleneck inwall, and bottle closure of rubber ring surface and bottleneck ring surface form second hermetically-sealed construction under the thrust of aluminium lid, two seals structure like this significantly enhances the sealing property of bottle closure of rubber to glass bottle.

For the utility model structure, the magnitude setting of circular groove 2 is not limited to twice.

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.
