Description

A kind of double containment bottle cap
Technical field
The utility model relates to a kind of bottle cap, particularly relates to a kind of double containment bottle cap.
Background technology
Bottling liquid class sealing is at present mainly continued to use screw thread class bottle cap and cork always or is disposablely torn, shears the plastic packaging bottle cap; Packing seal sealed and screw threads for fastening at the bottom of screw thread class bottle cap adopted bottle cap; This technology sealing is single, generally adopts packing seal to form face sealing, and sealing effectiveness is not good.And beverage, edible oils liquid use once tear, the shearing sealing structure, it is no longer tight to tear the back sealing, must short-term uses up, producing wastes, especially lining cement class effumability liquid can only use once usually.And the cork cost high, to use special-purpose uncork bottle opener.All there is unreasonable part in these structure designs.
The utility model content
The purpose of the utility model is to overcome above-mentioned deficiency of the prior art, and a kind of double containment bottle cap is provided.The good sealing effect of this double containment bottle cap, and it is simple in structure, easy to use, validity is strong, productive costs is low, is convenient to promote the use of.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts is: a kind of double containment bottle cap; Comprise body of the bottle lid; It is characterized in that: the bottom of said body of the bottle lid is provided with the bottle upper end and is threaded with the cylinder that is used to seal a bottle; Said body of the bottle lid bottom and the set inside that is positioned at cylinder have the rounding platform, and be domatic thereby the internal diameter on said cylinder top reduces to make the inwall on cylinder top to form taper from bottom to top gradually, is provided with the elastic seal packing ring between the outside face of the domatic and rounding platform of said taper.
Above-mentioned a kind of double containment bottle cap is characterized in that: be positioned at the domatic bottom of taper on the said cylinder and be provided with the connecting portion of thickness less than wall thickness of cylinder.
Above-mentioned a kind of double containment bottle cap is characterized in that: on the said rounding platform probe that is used to stretch into bottle is installed.
Above-mentioned a kind of double containment bottle cap is characterized in that: said cylinder, rounding platform and body of the bottle lid are one-body molded.
Above-mentioned a kind of double containment bottle cap is characterized in that: the top of said body of the bottle lid is spherical structure.
The utility model compared with prior art has the following advantages:
1, the utility model is simple in structure, and novel and reasonable design is easy to make.
2, the utility model has changed the sealing of traditional face Contact Pair, and it seals through two diatom Contact Pair, and along with the locking of bottle cap screw thread, the sealing of this double containment bottle cap is more and more tighter, has improved sealing effectiveness greatly.
3, the utility model is provided with the connecting portion of thickness less than wall thickness of cylinder through on cylinder, being positioned at the domatic bottom of taper; Thereby form the cyclic structure of a depression in the inboard of connecting portion; So enough accommodation spaces can be provided for the outer rim of elastic seal packing ring, when the elastic seal packing ring being squeezed when producing distortion, have certain extendable room; And in use, can form the line Contact Pair in the contact position, outer of elastic seal packing ring and bottleneck quickly and easily.
4, the realization cost of the utility model is low, and result of use is good, is convenient to promote the use of.
In sum, the utility model is simple in structure, novel and reasonable design, and functional reliability is high, long service life, and the good sealing effect of this double containment bottle cap, productive costs is low, is convenient to promote the use of.
Through accompanying drawing and embodiment, the technical scheme of the utility model is done further detailed description below.

Description of reference numerals:
The 1-body of the bottle lid; 2-rounding platform; 3-elastic seal packing ring;
The 4-cylinder; The 4-1-taper is domatic; The 4-2-connecting portion;

The specific embodiment
Like Fig. 1, Fig. 2 and a kind of double containment bottle cap shown in Figure 3; Comprise body of the bottle lid 1; The bottom of said body of the bottle lid 1 is provided with bottle 5 upper ends and is threaded with the cylinder 4 that is used to seal a bottle; The inwall of said cylinder 4 is provided with negative thread, and the outer wall of said bottle 5 upper ends is provided with the suitable outside thread of said negative thread, and said body of the bottle lid 1 bottom and the set inside that is positioned at cylinder 4 have rounding platform 2; Thereby the internal diameter on said cylinder 4 tops reduces to make the inwall on cylinder 4 tops to form the domatic 4-1 of taper from bottom to top gradually, is provided with elastic seal packing ring 3 between the outside face of domatic 4-1 of said taper and rounding platform 2.Preferred way is, said cylinder 4, rounding platform 2 and body of the bottle lid 1 are one-body molded.
In conjunction with Fig. 1, Fig. 2 and Fig. 3, during use, in the time of need bottleneck being sealed; Turn body of the bottle lid 1 makes cylinder 4 and bottle 5 upper end screws thread fit, screws gradually when cylinder 4 moves down, and this moment, elastic seal packing ring 3 was all pushed in the interior edge and the outer of bottleneck; So elastic seal packing ring 3 produces distortion, the interior line Contact Pair (seeing C place among Fig. 2) that forms along the contact position of elastic seal packing ring 3 and bottleneck; Elastic seal packing ring 3 forms another line Contact Pair (seeing B place among Fig. 2) with the contact position, outer of bottleneck; Along with constantly screwing of cylinder 4, the pressure between elastic seal packing ring 3 and the bottleneck is increasing, and the contact pressure of the line Contact Pair at B place and the line Contact Pair at C place is all increasing; Realized the bottleneck effective seal; The utility model seals through two diatom Contact Pair, has changed traditional face Contact Pair sealing, has improved sealing effectiveness.And because of elastic seal packing ring 3 has the better elastic performance, the sealing effectiveness of the line Contact Pair of its formation is better, and utilizes its better elastic recovery performance, uses durable.
As shown in Figures 2 and 3; The bottom that is positioned at the domatic 4-1 of taper on the said cylinder 4 is provided with the connecting portion 4-2 of thickness less than cylinder 4 wall thickness, and the inboard of connecting portion 4-2 forms the cyclic structure of a depression at this moment, so enough accommodation spaces can be provided for the outer rim of elastic seal packing ring 3; When elastic seal packing ring 3 is squeezed the generation distortion; Have certain extendable room, and in use, can be quickly and easily in the outer contact position formation line Contact Pair of elastic seal packing ring 3 with bottleneck.
As shown in Figure 1; The probe 6 that is used to stretch into bottle 5 is installed on the said rounding platform 2,, can this double containment bottle cap be applied on the Instant cement bottle through probe 6 is set; When need taking out in the Instant cement bottle glue; The cylinder 4 of outwarding winding is removed being threaded between cylinder 4 and bottle 5 upper ends, picks a small amount of glue through probe 6 and uses.The top of said body of the bottle lid 1 is spherical structure.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any restriction; Every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection domain of the utility model technical scheme.
