Abstract

The utility model relates to a sealing cover for a bucket, which comprises a cover body and a sealing ring, wherein the bottom of the cover body is opened, buckle rings are arranged on the inner circumference of the cover body, clamping grooves are formed between the buckle and the inner top surface of the cover body, and the sealing ring is arranged on the inner circumference of the clamping groove, and sealed ridges are arranged on the inner circumference of the sealing ring. According to the sealing cover provided by the utility model, the sealing ring of the sealing cover is arranged on the inner circumference of the clamping groove, when the bottle opening of the bucket is clamped in the clamping groove, the sealing ring is compressed and deformed, and the outer periphery and the parietal margin of the bottle opening are coated with the deformed sealing rings, so that the bottle opening is sealed, and the sealing effect is better than the sealing mode that the sealing ring and the bottle opening are in contact with each other in the prior art; and as sealed ridges are arranged on the inner circumference of the sealing ring, which are in contact with the bottle opening better, the sealing performance is improved; and the material cost of the sealing ring is small when compared with that in the prior art, so that manufacturing cost is saved.

Description

The bucket seal cover cap

Technical field

The utility model relates to the used for canned water seal cover cap, particularly carries the bucket seal cover cap of seal ring.

Background technology

The lid of existing bottled water generally has two kinds, a kind of lid is not have seal ring, the lid bottom opening, the lid inwall is provided with draw-in groove, when lid is installed, put packing seal (foamed gaskets) earlier at the bucket bottle mouth position, then the lid opening is aimed at the bucket bottleneck and be inserted in, until the flange of draw-in groove fastening bucket bottleneck periphery, make packing seal be pressed in the bucket bottleneck and realize sealing; The deficiency of this lid is that packing seal do not fix with lid or bottleneck, during installation easily because its displacement or purse up etc.s causes bottleneck not seal fully, cause leak, gas leakage etc., cause the pollution of inner bucket water source.Another kind of lid is that self has seal ring, as China Patent No. CN201120234080.9 in disclosed a kind of bottle cap for the bottled water antiseep on January 18th, 2012, comprise the lid that is installed on the staving water outlet, covered body wall is provided with the handle for unpacking, the lid center of top is provided with water inlet, water inlet is provided with for the interior pipe for the turnover of water dispenser unpacking device, wherein, is mounted with elastomeric sealing and anti-leakage circle on the arc groove of the junction of lid top and sidewall.The sealing and anti-leakage circle of this kind of bottle cap is arranged on the circular arc corner in lid inner top and interior week, and this position is far away apart from bottleneck, causes the materials amount of sealing and anti-leakage circle more, otherwise the sealing and anti-leakage circle can not contact with bottleneck, so that can not seal; In addition, the sealing and anti-leakage circle only contacts with bottleneck edge, and its area of contact is little, and sealing effectiveness is relatively poor.

The utility model content

The purpose of this utility model is to overcome the deficiency that above-mentioned prior art exists, and provides a kind of simple and reasonable for structure, and good sealing effect, the bucket seal cover cap that cost is low are to overcome the deficiencies in the prior art.

The purpose of this utility model is achieved in that

A kind of bucket seal cover cap comprises lid and seal ring, week is provided with clasp in the lid bottom opening, lid, forms draw-in groove between clasp and the lid inner top surface, it is characterized in that: described seal ring is arranged on week in the draw-in groove, week is provided with seal bead in the seal ring.

The purpose of this utility model can also adopt following technical measures to solve:

As a kind of scheme more specifically, extend baffle plate under the described lid inner top surface, form cell body between week in baffle plate and the draw-in groove, insert in the cell body seal ring upper end.By setting up baffle plate, can prevent effectively that seal ring from peeling off lid.

Described seal bead is provided with two, and two seal bead are arranged at the two ends up and down in week in the seal ring respectively.

The beneficial effects of the utility model are as follows:

(1) seal ring of this kind of bucket seal cover cap is arranged on week in the draw-in groove, when the bucket bottleneck buckles into draw-in groove, seal ring is extruded distortion, seal ring after the distortion wraps the periphery of bottleneck and the upper edge of bottleneck, thereby with the bottleneck sealing, its sealing effectiveness is better than the sealing means that seal ring contacts with the bottleneck apical margin in the prior art;

(2) week be provided with seal bead in the seal ring, seal bead can have better the contact with bottleneck, improves sealing property;

(3) the materials amount of seal ring is little than prior art, has saved tooling cost.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described.

In conjunction with illustrated in figures 1 and 2, a kind of bucket seal cover cap comprises lid 1 and seal ring 2, lid 1 bottom opening is provided with clasp 11 week in the lid 1, forms draw-in groove 12 between clasp 11 and lid 1 inner top surface, described seal ring 2 is arranged on week in the draw-in groove 12, is provided with seal bead 21 in the seal ring 2 week.

Extend baffle plate 13 under described lid 1 inner top surface, form cell body between week in baffle plate 13 and the draw-in groove 12, insert in the cell body seal ring 2 upper ends.

Described seal bead 21 is provided with two, and two seal bead 21 are arranged at the two ends up and down in week in the seal ring 2 respectively.

Main and the five gallon bottle bucket 3 of above-mentioned bucket seal cover cap is used, and the bottleneck periphery of five gallon bottle bucket 3 is provided with flange 31, and the draw-in groove 12 of lid 1 cooperates with described flange 31.Seal ring 2 is made with the material that lid 1 is respectively different, and both are injected into one.

Its sealing principle is: referring to Fig. 3 and Fig. 4, behind the five gallon bottle bucket 3 dress water, the bottom opening of lid 1 is aimed at the bottleneck of five gallon bottle bucket 3, also past bottleneck overcoat, after the flange 31 of bottleneck passes through clasp 11 by force, flange 31 is stuck in the draw-in groove 12, seal ring 2 is extruded distortion, and the seal ring 2 after the distortion wraps the periphery of flange 31 and the upper edge of flange 31, thereby bottleneck is sealed.
