Abstract

The utility model relates to a bottle cap sealing structure which comprises a bottle opening and a cap body, wherein the peripheral surface of the bottle opening is in threaded connection with the inner circumferential surface of the cap body; the lower end of the cap body is connected with an anti-counterfeiting ring; a convex ring is arranged on the peripheral surface of the lower part of the bottle opening and is located between the lower end surface of the cap body and the anti-counterfeiting ring; at least one side sealing ring is arranged on the upper end surface in the bottle cap; the inner side surface or/and outer side surface of the side sealing ring is/are in contact with the top end of the bottle opening; the inner circumferential surface of the lower part of the cap body is a conical surface; the upper end surface of the convex ring is an inclined surface; and the inner circumferential surface of the lower part of the cap body is in contact with the upper end surface of the convex ring. The bottle cap sealing structure provided by the utility model realizes the sealing of the lower part of the bottle opening, and prevents the sundries such as dust and the like from entering the clearance between the bottom opening and the cap body from the space between the lower part of the bottle opening and the cap body so as to avoid bacterium breeding and guarantee the hygiene in use. Moreover, the bottle cap sealing structure also can seal the upper part of the bottle opening perfectly.

Description

A kind of hermetically-sealed construction of bottle cap

Technical field

The utility model relates to a kind of hermetically-sealed construction of bottle cap, refers 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.

The utility model content

The utility model technical matters to be solved 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 utility model adopts is: a kind of hermetically-sealed construction of bottle cap comprises bottleneck, lid; Said bottleneck outer peripheral face is threaded with the lid inner peripheral surface, and the lower end of lid is connected with false proof ring, and bottleneck lower, outer perimeter face is provided with bulge loop; 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, and 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 the conical surface; The upper surface of said bulge loop is the inclined-plane, and the upper surface of lid bottom inner peripheral surface and bulge loop is inconsistent.

Said seal ring with the inconsistent face in bottleneck top be arcwall face.

The beneficial effect of the utility model is: 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 a kind of bottle cap of the utility model is done further to describe in detail below.

As shown in Figure 1, a kind of 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, and 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; 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 the conical surface 6, and the upper surface of said bulge loop 5 is the inclined-plane, and the upper surface of lid 2 bottom inner peripheral surfaces and bulge loop 5 is inconsistent.

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 the protection category of the utility model.

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 conical surface 6 of lid 2 bottom inner peripheral surfaces and the inconsistent sealing that realizes bottleneck 1 bottom in inclined-plane, upper end of bulge loop 5; Same when having certain Mismachining tolerance in the actual production process; Can remedy these errors through the elasticity modification of lid 2 bottoms, keep inconsistent state between the conical surface 6 of assurance lid 2 bottom inner peripheral surfaces and the inclined-plane, upper end of bulge loop 5, thereby guaranteed 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 utility model; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.
