The specific embodiment

Can more be expressly understood above-mentioned purpose of the present utility model and beneficial effect with following explanation in conjunction with the accompanying drawings.

At first, see also Fig. 2, Fig. 2 is the cover configuration scheme drawing of the utility model one embodiment, this body of the bottle lid 30 is integrally formed plastic objects, its principal character is as described below: it is made that body of the bottle lid 30 can be plastic substance, it is that the end sealing other end then is the hollow lid of hollow out, its inwall is provided with a threaded portion 33, the ora terminalis at its hollow out place is equipped with a seal ring 34 with locking container finish, its caping 31 closed end peripheries extend internally to dash forward and establish the leakproof flange 32 of a ring-type, (please cooperate the upper edge portion system of consulting this leakproof flange 32 of Fig. 5 to be provided with an arc portion 321, and extension downwards becomes the contraction flow region 322 at a trickle angle of inclination, inwardly be shrunk to a ring-type by this contraction flow region 322 and support subsides portion 323, this leakproof flange 32 must form one with bottleneck 40 by this subsides portion 323 that supports that is convexly equipped with and well contact, and make it have flexible so when pressurization locking, this leakproof flange 32 can be along with the exert pressure size of degree of locking, and the toughness that this contraction flow region 323 is produced in various degree, and do contacting in various degree with bottleneck 40.

See also Fig. 3, when threaded portion 33 is rotated into bottleneck 40 and screws, when being under pressure, leakproof flange 32 will make this contraction flow region 322 form a plane because of it is flexible, contact completely with bottleneck 40, and it will be placed in these bottleneck 40 internal diameters fully to subsides portion 323, make this bottleneck can reach the effect of sealing fully and leakproof; Consult Fig. 4 again, when the threaded portion 33 of the utility model body of the bottle lid 30 does not screw with bottleneck 40, these leakproof flange 32 pressures are limited, so this contraction flow region 322 is less with the area of contact of bottleneck 40, fail to do to fit fully with bottleneck 40, but the root edge end that should support subsides portion 323 has been placed in the internal diameter of this bottleneck 40, therefore this bottleneck 40 reaches complete leak free effect too, so bottle body 30 of the present utility model screws the size of degree by it, do contacting in various degree with bottleneck 40, to reach the effect of better sealed against leakage.

And the setting of the arc-curved part 321 of the utility model leakproof flange 32, be that a kind of wound that has the environmental protection notion is thought, because of its arc portion 321 when this body of the bottle lid 30 engages with bottleneck 40, form an elastic space between the two at it, and this elastic space will make leakproof flange 32 of the present utility model have splendid toughness, the elasticity of this leakproof flange 32 does not go down when repeating to re-use again after use, therefore body of the bottle lid 30 of the present utility model has nonexpondable effect, is a kind of utility model that meets economic benefit.

In known container closure as can be known, all reasons that container can't careful envelope leakproof that makes are arranged, elasticity defective and the not good problem that causes of bottleneck cylindricity such as the leakproof flange, and the environmental issue of society care, after the utility model comes out, the improvement and the environmental issue of leakproof flange commonly used all are readily solved, and the utility model is for the not good problem of the cylindricity of the bottleneck that the producer perplexed, in the utility model, can obtain more complete improvement, because of being provided with a contraction flow region in the body of the bottle lid of the present utility model, and this contraction flow region is the structure that is an inclined-plane and has toughness, when the bottleneck that is covered is the not good product of cylindricity, can be by this bottleneck being done a preferable applying by the ductile structure of this contraction flow region, and make its container have the effect of leakproof seal equally, not because of the not good bad quality that causes of its bottleneck cylindricity.

Comprehensively above-mentioned, we can know and the utlity model has following advantage, and are specific as follows:

1. leakproof flange of the present utility model and the structure that is one of the forming with body of the bottle lid thereof, the structure of the more known leakproof flange of its leakproof flange has more toughness, and the situation of seepage liquid or gas in use can not take place, the product that the producer is produced is no longer bad because of the tightness of bottle cap, and influences the quality of this product.

2. leakproof flange of the present utility model is the structure that is one of the forming with body of the bottle lid, and the arc portion that the upper end of this leakproof flange is set, can make this leakproof flange strengthen this elastic strength and be not easy to cause elastic fatigue, and this more increases the Occupation coefficient of the utility model body of the bottle lid, more a kind of innovation that meets economic benefit except meeting the environmental protection notion.

Since lid interlocking of the present utility model behind bottleneck, the contraction flow region that had both formed the leakproof flange forms with bottleneck and contacts, can be located in the bottleneck and should support subsides portion, and closely recline because of adhesive ability and bottleneck, no matter when therefore whether bottle cap of the present utility model locks fully, can both produce good sealing function between bottleneck and body of the bottle lid, do not cause the product in the container to produce phenomenons such as leaking gas, addle, go bad, so that the customer feels at ease to choose, and increase the quality prestige of manufacturer simultaneously.

4. and the setting of leakproof flange of the present utility model is the design of an excellent toughness by it, so the user need not to spend too that great strength lock onto it on bottleneck, can it reach the sealing effectiveness of expection as long as reverse this body of the bottle lid gently.

Take a broad view of above-mentioned, structure of the present utility model, feature can provide a kind of lid with leakproof seal effect really, really have practicality and progressive with its single-piece combination and space kenel, both be not seen in like product, also do not see open before the application, meet the requirement of patent law, so propose utility application in accordance with the law.
