Abstract
The invention relates to a sealing structure of a bottle cap, which comprises a bottle opening and a cap body. The outer peripheral surface of the bottle opening is connected with the inner peripheral surface of the cap body in a threaded manner, an anti-counterfeiting ring is connected to the lower end of the cap body, a convex ring is disposed on the outer peripheral surface of the lower portion of the bottle opening and positioned between the lower end surface of the cap body and the anti-counterfeiting ring, at last one side sealing ring is arranged on the inner upper end surface of the bottle cap, the inner side surfaces and/or the outer side surfaces of the side sealing rings are abutted to the top end of the bottle opening, and a lip is disposed on the inner peripheral surface of the lower portion of the cap body and abutted to the convex ring. The sealing structure of the bottle cap has the advantages that the lower portion of the bottle opening is sealed, accordingly, impurities such as dust and the like are prevented from entering a gap between the bottle opening and the cap body from a space between the lower portion of the bottle opening and the cap body, growth of bacteria is prevented, and service sanitation is guaranteed. In addition, the upper portion of the bottle opening can be more effectively sealed by the aid of the sealing structure.
Description
Technical field
The present invention relates to a kind of hermetically-sealed construction of bottle cap, refer more particularly to a kind of hermetically-sealed construction of cap-rotating type bottle cap.
Background technology
The structure of present employed bottle cap is as shown in Figure 2 mostly; Comprise bottleneck 1, lid 2; Said bottleneck 1 outer peripheral face is threaded with lid 2 inner peripheral surfaces, is provided with seal ring 3 between upper surface and bottleneck 1 top end face in the lid 2, and the lower end of lid 2 is connected with false proof ring 4; Bottleneck 1 lower, outer perimeter face is provided with bulge loop 5, and bulge loop 5 is positioned at the annular groove 6 of lid 2 lower surfaces and false proof ring 4 formation.When it used, the lid 2 of screwing made the sealing on seal ring 3 and the inconsistent realization bottleneck of bottleneck 1 top end face 1 top.
The shortcoming of above-mentioned Bottle cap structure is: 1, because sealing is not realized in bottleneck 1 bottom, cause dust and other impurities can between bottleneck 1 bottom and lid 2, get into the gap 7 of bottleneck 1 and lid 2, cause bacteria breed, influence is used; 2, the hermetically-sealed construction on bottleneck 1 top is very unreliable, and the bottle cap of said structure is after lid 2 and bottleneck 1 are screwed; Distance in the lid 2 between upper surface and bottleneck 1 top end face is a fixed value; Have only when the thickness of seal ring 3 and could realize sealing when fixed value equates fully therewith, but in the actual production process, inevitably have certain error; Thereby the thickness that causes seal ring 3 fixed value fully therewith equates, thereby causes bottleneck 1 top seal poor effect.
Summary of the invention
Technical matters to be solved by this invention is: provide a kind of and can not only make the bottleneck top seal better and can realize the hermetically-sealed construction of the bottle cap of bottleneck lower seal.
For addressing the above problem, the technical scheme that the present invention adopts is: the hermetically-sealed construction of bottle cap comprises bottleneck, lid; Said bottleneck outer peripheral face is threaded with the lid inner peripheral surface; The lower end of lid is connected with false proof ring, and bottleneck lower, outer perimeter face is provided with bulge loop, and bulge loop is between lid lower surface and false proof ring; The upper surface is provided with at least one side seal ring in the described bottle cap; The medial surface of side seal ring is or/and inconsistent between lateral surface and the bottleneck top, and said lid bottom inner peripheral surface is provided with the lip limit, and lip limit and bulge loop are inconsistent.
The upper surface of said bulge loop is the inclined-plane, and the upper surface of said lip limit and bulge loop is inconsistent.
Said seal ring with the inconsistent face in bottleneck top be arcwall face.
The invention has the beneficial effects as follows: the hermetically-sealed construction of above-mentioned bottle cap; It has realized the lower seal of bottleneck; Thereby avoided dust and other impurities between bottleneck bottom and lid, to get into the gap of bottleneck and lid, thereby can not cause bacteria breed, the health when having guaranteed to use.In addition, it is better that it can also make the bottleneck top seal.

The specific embodiment
Through specific embodiment the hermetically-sealed construction of bottle cap of the present invention is done further to describe in detail below.
As shown in Figure 1, the hermetically-sealed construction of bottle cap comprises bottleneck 1, lid 2; Said bottleneck 1 outer peripheral face is threaded with lid 2 inner peripheral surfaces, and the lower end of lid 2 is connected with false proof ring 4, and bottleneck 1 lower, outer perimeter face is provided with bulge loop 5; Bulge loop 5 is between lid 2 lower surfaces and false proof ring 4; The upper surface is provided with at least one side seal ring 3 in the described bottle cap, is two side seal rings 3 in the present embodiment, and the medial surface of side seal ring 3 is or/and inconsistent between lateral surface and bottleneck 1 top; Said lid 2 bottom inner peripheral surfaces are provided with lip limit 6, and lip limit 6 is inconsistent with bulge loop 5.
As preferred version, the upper surface of said bulge loop 5 is the inclined-plane, and lip limit 6 is inconsistent with the upper surface of bulge loop 5, through the mutually enantiotropy of lip limit 6 with the inclined-plane, thereby can guarantee reliable tightness so that lip limit 6 can be conflicted closelyr with bulge loop 5.
As preferred version, said side seal ring 3 with the inconsistent face in bottleneck 1 top be arcwall face.Certainly also can or facing directly for the inclined-plane with the inconsistent face in bottleneck 1 top of side seal ring 3 all belongs to protection category of the present invention.
The hermetically-sealed construction of above-mentioned bottle cap; Medial surface through side seal ring 3 is or/and the inconsistent sealing that realizes bottleneck 1 top between lateral surface and bottleneck 1 top; When having certain Mismachining tolerance in the actual production process; Can remedy these errors through the elasticity modification of side seal ring 3, guarantee the medial surface of side seal ring 3, thereby guarantee the sealing effectiveness on bottleneck 1 top or/and keep inconsistent state between lateral surface and bottleneck 1 top; In addition; The inconsistent sealing that realizes bottleneck 1 bottom between the inclined-plane, upper end through lip limit 6 and bulge loop 5; Same when having certain Mismachining tolerance in the actual production process; Can remedy these errors through the elasticity modification on lip limit 6, keep inconsistent state between the inclined-plane, upper end of assurance lip limit 6 and bulge loop 5, thereby guarantee the sealing effectiveness of bottleneck 1 bottom.After sealing is realized in bottleneck 1 bottom, avoided dust and other impurities between bottleneck 1 bottom and lid 2, to get into the gap 7 of bottleneck 1 and lid 2, thereby can not cause bacteria breed, the health when having guaranteed to use.
The above embodiments are the principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used to limit the present invention; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
