Description

A kind of easy-to-pull bottle cap

The utility model relates to a kind of and the matching used bottle cap of bottle, especially is applicable to a kind of easy-to-pull bottle cap of Packaging Bottle such as beer, rice wine, carbonated drink.

Existing bottle lid all needs opener, inconvenient and fragile bottleneck when generally using.The patent No. is a kind of easy-open bottle lid of 95207697.8, and its draw ring is connected with lid, and the both sides, junction are the indentation lines that do not cut.But this bottle cap exists some not enough: the one, and draw ring needs to be connected with lid, and the junction often influences leak tightness; The 2nd, the power of will seeking to achieve breakthrough during uncork is bigger, has influenced use; The 3rd, draw ring protrudes caping, is difficult for being accepted by existing sealing device.

The purpose of this utility model is to overcome the deficiency of above-mentioned prior art and provides a kind of unlatching convenient, and good airproof performance, uncork break through the easy-to-pull bottle cap that power is little, existing installation is suitable for.

The utility model is achieved by the following technical solution: easy-open lid is designed to the split formula, promptly is made up of lid and the sealed bolster plate of band skirt pleat.Sealed bolster plate lining seal ring mainly seals, and does not connect owing to do not relate to bezel ring,, so leak tightness is better.Lid mainly plays a part the backing plate compression set at bottleneck, and the draw ring on the lid then plays the uncork effect.Concrete scheme is, the lid top is gone up and kept bezel ring,, and middle draw ring fuses by linkage section and bezel ring,, two indentation lines along the linkage section dual-side until the skirt ruffle that covers; Lid is embedded with the sealed bolster plate that matches.When the linkage section width was wide more, the angle between linkage section and the bezel ring, was more little, and stress is concentrated at Jiao Dingchu during uncork, thereby breakthrough power is less.

The utility model can also come perfect by following technical solution: the one, establish flange at sealed bolster plate, and flange both can play the guiding role when backing plate embeds lid, helped forming seal ring again.The 2nd, need determine diameter by the bottleneck leak free, dash a circular groove in the sealed bolster plate outside.Groove at first can hold draw ring, as long as draw ring size and groove are adapted, imbeds wherein, and then this bottle cap is promptly easily received by existing sealing device; Secondly can gain in strength, make backing plate can bear bigger pressure of the inside of a bottle; Groove inside promptly is a bulge loop, and the O-ring seal that can instil between bulge loop and flange and the lid keeps sealing process constant.

Compared with the prior art the utility model has good airproof performance, and the power that breaks through during uncork is little, and the advantage that can use on existing sealing device is used very convenient.

Fig. 1 is the structural representation of easy-to-pull bottle cap.

Fig. 2 is the cross-sectional schematic of embodiment 2.

The utility model will be further described below in conjunction with drawings and Examples.

Embodiment 1.As shown in Figure 1, this bottle cap is made up of lid 1 and sealed bolster plate with matching 2.Lid 1 top is gone up and is kept bezel ring, 1-1, and middle draw ring 1-2 fuses by linkage section 1-3 and bezel ring,, two indentation line A and B along linkage section 1-3 both sides until the skirt ruffle of lid.Sealed bolster plate 2 embeds in the lid 1 in advance, as long as lining back seal circle can seal various bottles.

Embodiment 2.On the basis of embodiment 1, do 2 improvement, see Fig. 2.The one, establish flange 2-1 at sealed bolster plate 2; The 2nd, need determine diameter by the bottleneck leak free, dash a circular groove 2-2 in sealed bolster plate 2 outsides.Backing plate 2 embeds in the lid 1 in advance, needs only instillation O-ring seal 3 between groove and flange and lid, and the utility model can use on bottle seal equipment.
