Abstract
A bottle lid comprises an end lid and a lid body. Single thread and crotch line are provided on the lid body. The crotch line circles the lid body. The lid body below the crotch line forms an assurance circle. An inner seal is arranged below the end lid. The periphery of the inner seal is provided with an arc flange. An outer seal is provided below the end lid of the bottle lid. When opening the bottle lid, the air can let out only after the bottle lid rotates by 360 DEG and the air entering angle is larger than the rupture angle of the assurance ring so that the seal and fake preventing abilities of the bottle lid are improved.
Description
The utility model relates to a kind of bottle cap, especially a kind of two heat filling beverage threaded caps that seal that do not add any interior pad.
The structure of existing bottle cap generally comprises end cap and lid, on lid, be provided with single screw thread, be used for being screwed in bottleneck, on lid, also be provided with line of weakness with the screw thread fit of bottleneck, line of weakness forms a safety loop around one week of lid, when opening bottle cap, spiral tension force makes the line of weakness fracture on the safety loop, thereby plays false proof effect, general bottle cap is lined with pad in end cap inside, when bottle cap is spun on bottleneck, rely on pad extruding bottleneck, play the leak free effect.But rely on the pad crush seal, pad is an aspect, often causes gas leakage when being squeezed in bottleneck owing to squeese pressure is inhomogeneous, when opening bottle cap, between the bottle cap half-twist-180 ° gas leakage is just arranged usually, seal and anti-counterfeiting performance not good.
The purpose of this utility model is by Bottle cap structure is improved, and makes that when opening bottle cap, bottle cap after rotating 360 ° gas leakage takes place, to improve the sealing and the anti-counterfeiting performance of bottle cap.
To achieve these goals, the technical solution of the utility model is as follows:
Have in one at the end cap of bottle cap and to seal, in seal outer being with and be convexly equipped with a flange, when bottle cap is screwed in bottleneck, in seal and fill in the bottleneck bottleneck in the flange contact.Also be provided with outer sealing under the bottle cap caping, bottle cap covers when bottleneck, seals lower edge contact bottleneck upper limb outward.The squeese pressure vertical axial that seals outward acts on bottleneck; In the squeese pressure of sealing act radially on bottleneck, thereby make that when opening bottle cap, bottle cap after 360 ° of rotations gas leakage takes place, and safety loop ruptured in the past in rotating 360 °, so guarantee the fracture angle of air inlet angle greater than safety loop.
By adopting technique scheme, make when opening bottle cap, the air inlet angle of rotation bottle cap has improved the sealing and the anti-counterfeiting performance of bottle cap greater than the fracture angle of safety loop.
Below in conjunction with drawings and Examples the utility model is described further, in the accompanying drawing,
Fig. 1 is the cutaway view of bottle cap of the present utility model.
As shown in Figure 1, bottle cap 1 comprises end cap 11 and lid 12, on lid, be provided with single screw thread 121, be used for being screwed in bottleneck with the screw thread fit of bottleneck, also be provided with line of weakness 122 on lid, line of weakness 122 is around one week of lid, the cap portion of line of weakness below 122 forms a safety loop 123, when opening bottle cap 1, spiral tension force makes line of weakness 122 fractures on the safety loop 123, thereby plays false proof effect.Have at the end cap 11 of bottle cap and to seal 111 in one, in seal 111 outer being with and be convexly equipped with a curved flanges 112, when bottle cap 1 is screwed in bottleneck, in seal 111 and fill in the bottleneck bottleneck in flange 112 contacts.End cap also is provided with for 11 times outside one and seals 113, and bottle cap covers when bottleneck, seals 113 lower edge contact bottleneck upper limbs outward.Seal 113 squeese pressure vertical axial outward and act on bottleneck; In seal 111 squeese pressure and act radially on bottleneck, make when opening bottle cap, bottle cap is after 360 ° of rotations, gas leakage just takes place, and safety loop ruptured for 360 ° in the past in rotation, so guarantee the fracture angle of air inlet angle, therefore firmly and closely sealing be provided greater than safety loop.
Claims (2)
1. a bottle cap comprises end cap and lid, is provided with single screw thread and line of weakness on lid, and line of weakness is around one week of lid, and the following cap portion of line of weakness constitutes a safety loop, it is characterized in that: have at the end cap of bottle cap and seal outside sealing with one in one.
2. bottle cap according to claim 1 is characterized in that: seal the periphery in described and be convexly equipped with a flange.
