Abstract

The utility model provides a sealing bottle cover which comprises a bottle cover body, and inner threads are arranged on the inner wall of the bottle cover body. The sealing bottle cover is characterized in that a sealing ring made of elastic materials is further included and arranged in the top of the bottle cover body. The sealing ring is made of the elastic materials, so that airtight matching of the bottle cover and a bottle is guaranteed, the packaging technology is simplified due to the fact that the bottle cover and the sealing ring are integrated, the sealing effect can be achieved by directly screwing the bottle cover on the bottle, the sealing effect can be maintained by screwing the bottle cover again after the bottle is unsealed, and the quality guarantee period of bottled objects is effectively prolonged. The sealing bottle cover is simple in structure, simple in packaging technology, good in sealing effect and capable of guaranteeing pollution-free storage of drugs.

Description

Seal bottle cap

Technical field

The utility model belongs to bottle cap field, is specifically related to a kind of seal bottle cap.

Background technology

In productive life, a large amount of article need sealed storage, particularly medicine, and the quality of storage leakproofness is to its effect and subject word important.The packing seal that the sealing of existing bottled medicine is normally made by aluminium foil and paper is closed in bottleneck, and its shortcoming is: it is unreliable to seal, and owing to lacking flexibility, sealing pad is difficult for forming airtight cooperation with bottleneck; Assembly technology complexity, needs electromagnetic induction capper to heat sealing pad; Behind Kaifeng, lose obturation effect.Also have the gasket seal that adopts aluminium foil and rubber to make, although this pad has good leakproofness, rubber can move, thereby pollutes medicine.

Utility model content

The purpose of this utility model is that a kind of good leak tightness of proposition, technology of the package simply, do not produce the seal bottle cap of pollution.

The technical solution of the utility model is achieved in that a kind of seal bottle cap, comprises body of the bottle lid, and this body of the bottle lid inwall is provided with negative thread, it is characterized in that: also comprise the seal ring of being made up of elastomeric material, be arranged at the top in described body of the bottle lid.

Seal ring is made and can be guaranteed that bottle cap and bottle are airtight and coordinate by elastomeric material, bottle cap and seal ring are set together and have simplified technology of the package, directly bottle cap is tightened in and on bottle, reaches sealing effectiveness, and behind Kaifeng, tighten again bottle cap and can continue to keep obturation effect, effectively extend the shelf-life of bottled food.

Further, described seal ring comprises upper ring and circular lower circle, on this, the interior nose circle of circle radially extends the annular inner wall joining with this lower circle downwards, on this, the outer nose circle of circle radially extends annular outer wall downwards, this inwall, on this, circle forms an annular chamber together with this outer wall, and described body of the bottle lid upper inside wall is provided with the annular groove that sealing circle is installed.When tighten bottle cap on bottle time, bottleneck is placed in annular chamber, has better obturation effect.

Further, the angle that described inwall and described outer wall and described upper circle form is obtuse angle, and the cross section that makes described annular chamber is trapezoidal, and this is trapezoidal lower large little, is easy to bottleneck and inserts in annular chamber; This trapezoidal top length of side is set to be slightly less than the wall thickness of joined bottleneck, tightens after bottle cap, and interference fit is formed at bottleneck and annular chamber dual-side top, makes dual-side also form airtight cooperation with bottleneck sidewall, thereby reaches better sealing effectiveness.

Described seal ring is made up of polythene material, and polyethylene has good elasticity, and its Stability Analysis of Structures can not produce migration, thereby can not pollute medicine.

The utility model is simple in structure, and technology of the package is easy, and good sealing effect guarantees the pollution-free storage of medicine.

Accompanying drawing explanation

Fig. 1 is the structural representation of an embodiment of the utility model seal bottle cap;

Fig. 2 is the structural representation of seal ring;

Fig. 3 is the application scheme of installation of sealing bottle cap;

In figure: 1-body of the bottle lid, 2-seal ring, 3-bottle, 11-annular groove, the upper circle of 21-, encloses under 22-, 23-inwall, 24-outer wall, 25-annular chamber, the top length of side in W-annular chamber cross section.

The specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.

Seal bottle cap as shown in FIG. 1 to 3, comprises body of the bottle lid 1 and seal ring 2, and this body of the bottle lid 1 inwall is provided with negative thread, and sealing circle 2 is made up of polythene material, is arranged at the top in body of the bottle lid 1.

Described seal ring 2 comprises upper ring 21 and circular lower circle 22, on this, the interior nose circle of circle 21 radially extends the annular inner wall 23 joining with this lower circle 22 downwards, on this, the outer nose circle of circle 21 radially extends annular outer wall 24 downwards, this inwall 23, on this, circle 21 forms an annular chamber 25 together with this outer wall 24, this annular chamber 25 is for holding the bottleneck 31 of bottle 3, the diameter of its diameter and bottleneck 31 adapts, and described body of the bottle lid 1 upper inside wall is provided with annular groove 11, for sealing circle 2 is installed.

More preferably, described inwall 23 and described outer wall 24 are obtuse angle with the angle that described upper circle 21 forms, the cross section that makes described annular chamber 25 is trapezoidal, and trapezoidal top length of side W is set to be slightly less than the wall thickness of joined bottleneck 31, and making to tighten annular chamber 25 after bottle cap is interference fit with bottleneck 31.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
