Description

A kind of seal ring structure of edible oil bottle Pull ring cover

Technical field

This utility model relates to seal ring structure, the seal ring structure of a kind of edible oil bottle Pull ring cover.

Background technology

At present, in the seal ring structure for edible oil bottle Pull ring cover, it is all to use to face design, usual sealing ring diameter ratio directly Internal diameter of the bottleneck big 0.7mm to 1mm interference tight fit, when bottle cap is arranged on bottleneck, pressure is bigger than normal occurs that assembling is not in place, askew The phenomenon of lid, causes sealing ring to coordinate leakage of oil, the most as illustrated in fig. 1 and 2, is provided with sealing ring 6, sealing ring bag in this bottle cap Include guide part 603, sealing surface 601 and sealing ring inner surface 602.Owing to this bottle cap material is polyethylene, in the mould molding demoulding During contraction distortion relatively big, it is not very tight for coordinating when this bottle cap is assemblied on oil bottle neck, adds the density of general edible oil For 0.93g/cm³Left and right, it is easy to seepage occurs.Additionally edible oil processing factory fill, package after piling to be passed through, carrying, The links such as transport come into the market to sell, and the oil bottle after packaging can be caused the most unavoidably to collide, extrude, fall, whole Individual oil bottle cap includes that sealing ring to bear the biggest interior pressure, and now oil bottle cap can lose toughness under the effect of external force and deforms once again Oil leakage phenomenon occurs.Once occur that leakage of oil not only can cause economic loss, more seriously can cause edible oil safety, quality accident, Result in greater loss to factory and country.

Utility model content

The purpose of this utility model is to provide a kind of good sealing effect, service life length, edible oil bottle Pull ring cover that anti-pressure ability is good Seal ring structure.

This utility model provide technical scheme be: the seal ring structure of a kind of edible oil bottle Pull ring cover, including for edible oil The lid that bottleneck coordinates, is provided with the sealing ring in extending to edible oil bottleneck, outside described sealing ring in described lid Side is made up of annular cambered inner fovea part, annular cambered protuberance, annular cambered guide part the most successively, described annular arc Shape protuberance and edible oil bottleneck inwall interference fit.

In the seal ring structure of above-mentioned edible oil bottle Pull ring cover, one hollow bulb in besieged city, inner side of described sealing ring, described Hollow bulb be up-thin-low-thick truncated cone-shaped.

This utility model is after using technique scheme, and it has the beneficial effect that

It is not in place that this programme solves the assembling of edible oil cap, the problem of askew lid；Solve and anthropic factor cannot be avoided to cause bottle cap to leak The problem of oil, storage, piling, carry, the appearance of the link such as transport is collided, extrude, fall time the most indeformable of sealing ring Non-leakage to sealing function；Solve because weather and geographical position temperature cause oil bottle cap contraction distortion to be oozed when there is big difference The problem of leakage.Improve product quality, ensured edible oil quality safety, ensured that company exempts from economic loss.

Detailed description of the invention

Below in conjunction with detailed description of the invention, the technical solution of the utility model is described in further detail, but does not constitute this Any restriction of utility model.

Embodiment 1:

As shown in Fig. 3,4,5 and 6, the seal ring structure of a kind of edible oil bottle Pull ring cover, including for edible oil bottleneck 3 The lid 1 coordinated, the sealing ring 2 being provided with in extending to edible oil bottleneck 3 in described lid 1, described sealing ring 2 Outside be made up of annular cambered inner fovea part 21, annular cambered protuberance 22, annular cambered guide part 23 the most successively, Described annular cambered protuberance 22 and edible oil bottleneck 3 inwall interference fit, encircle a city in one in the inner side of described sealing ring 2 Sky portion 24, described hollow bulb 24 is up-thin-low-thick truncated cone-shaped.

In application process, the present embodiment uses the combination of annular cambered inner fovea part 21, annular cambered protuberance 22, Liang Zhejie Closing minimizing sealing ring 2 and contact the area of bottleneck, increase the compression and back elastic force of sealing ring 2, no matter compression increases or reduces, Sealing surface is always annular cambered protuberance 22.Edible oil bottle cover material is polyethylene, can be shunk by the change of temperature, due to Residing weather and geographical position difference, shrink relatively big when temperature is relatively low, sealing ring 2 size diminishes, and shrinks relatively when temperature is higher Little, sealing ring 2 becomes large-sized.No matter sealing ring 2 dimensional contraction is big or little, and annular cambered protuberance 22 is all the time as ring spring Sheet equally keeps enough elastic force to play sealing function.The most annular cambered guide part 23 reduces edible oil cap and is assemblied on bottleneck Pressure, solve edible oil cap assembling not in place, the problem of askew lid.

Above-described embodiment is this utility model preferably embodiment, but embodiment of the present utility model is not by above-described embodiment Restriction, other any without departing from the change made under spirit of the present utility model and principle, modify, substitute, combine, Simplify, all should be the substitute mode of equivalence, within being included in protection domain of the present utility model.

Claims (2)
