Description
Technical field
The utility model relates to a kind of structure of bowl cover, particularly a kind of bowl cover gas permeable member, in the process that can screw at bowl cover, keeps the air pressure of cup inner chamber steady preferably.
Background technology
Typically, the tegmentum of cup is in the process be covered, and due to the minimizing of cup inner chamber, the air pressure of its inside can rise, and typically, the ascensional range of this kind of air pressure can not impact the content of cup.But in the occasion that some are special, still need to keep the stable of cup internal gas pressure.At this point, present applicant proposes in a kind of process that can screw at bowl cover, keep the stable structure of cup internal gas pressure preferably.
Utility model content
The utility model, for the too complicated shortcoming of the stable apparatus structure of maintenance cup internal gas pressure similar in prior art, provides the bowl cover gas permeable member that a kind of structure is more succinct, can effectively realize keeping the steady of cup internal gas pressure while screwing bowl cover.
For achieving the above object, the utility model can take following technical proposals:
A kind of bowl cover gas permeable member, in the process that screws at bowl cover, keep the stable gas pressure of cup inner chamber, bowl cover is provided with external screw thread, and cup is provided with the internal thread matched with described external screw thread with it, and externally threaded side is provided with at least one air-vent; Air-vent is positioned at externally threaded upper limb, after described externally threaded upper limb refers to that bowl cover screws, and the position that bowl cover contacts with the end face of cup body one end.
In embodiment of the present utility model, described bowl cover comprises elastic ring; Described elastic ring extends around the circumferential direction of bowl cover, and elastic ring partly hides described air-vent.
In embodiment of the present utility model, described externally threaded upper limb is the lower edge of elastic ring, after the lower edge of described elastic ring refers to that bowl cover screws, and the edge that elastic ring contacts with the end face of cup body one end.
In embodiment of the present utility model, comprise the air-vent of at least 2 that are arranged at external screw thread side.
In embodiment of the present utility model, have at least the distance of an air-vent distance bowl cover lower end to be greater than the distance of other air-vent distance bowl cover lower ends, described bowl cover lower end refers to one end towards cup body of bowl cover.
In embodiment of the present utility model, the inner side of the lower edge of described elastic ring comprises projection, and described inner side refers to the part closer to bowl cover of the lower edge of elastic ring; Described projection extends along the circumferential direction of bowl cover.
In embodiment of the present utility model, described bowl cover also comprises the convex edge of protruding towards the lateral of bowl cover; After bowl cover screws, a side end face of described convex edge contacts with the end face of cup body one end.
The utility model has following remarkable technique effect:
Simple for structure, easily manufactured, manufacturing cost is comparatively cheap, and in the process that can effectively screw at bowl cover, keep the stable of cup internal gas pressure, be particularly about at bowl cover in the process screwed, in cup, gas can be overflowed by air-vent, until bowl cover is fully tightened, seals.
Accompanying drawing explanation
Fig. 1 is the general configuration schematic diagram of the cup at bowl cover gas permeable member place.
Fig. 2 is the bowl cover at bowl cover gas permeable member place and the structural representation of bowl cover gas permeable member.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail.
Embodiment 1
A kind of bowl cover gas permeable member, as shown in Figure 1, 2, for in the process that screws at bowl cover 100, keep the stable gas pressure of cup 200 inner chamber, bowl cover 100 is provided with external screw thread 110, cup body 300 is provided with the internal thread matched with described external screw thread 110, and externally threaded side is provided with at least one air-vent 400; Air-vent 400 is positioned at externally threaded upper limb, after described externally threaded upper limb refers to that bowl cover 100 screws, the position that bowl cover 100 contacts with the end face of cup body 300 one end, as the optional scheme of one, described bowl cover 100 also comprises the convex edge 101 of protruding towards the lateral of bowl cover 100; After bowl cover 100 screws, a side end face of described convex edge contacts with the end face of cup body 300 one end, and now, a side end face of convex edge 101, is generally lower surface and externally threaded upper limb.
Described bowl cover 100 comprises elastic ring 120; Described elastic ring 120 extends around the circumferential direction of bowl cover 100, and elastic ring 120 partly hides described air-vent 400.As preferably, elastic ring 120 hide air-vent 400 area should close to or reach the half of air-vent 400, particularly, after bowl cover 100 is screwed, after elastic ring 120 is compressed, can fully expose air-vent 400.
Described externally threaded upper limb 111 is the lower edge of elastic ring 120, after the lower edge of described elastic ring 120 refers to that bowl cover 100 screws, and the edge that elastic ring 120 contacts with the end face of cup body 300 one end.
Embodiment 2
A bowl cover gas permeable member described in above-described embodiment 1, its difference is, comprises the air-vent of at least 2 that are arranged at external screw thread side.
Have at least an air-vent 400 to be greater than the distance of other air-vent distance bowl cover 100 lower ends apart from the distance of bowl cover 100 lower end, described bowl cover 100 lower end refers to one end towards cup body 300 of bowl cover 100.
Embodiment 3
Bowl cover gas permeable member described in above-described embodiment, its difference is, the inner side of the lower edge of described elastic ring 120 comprises projection, and described inner side refers to the part closer to bowl cover 100 of the lower edge of elastic ring 120; Described projection extends along the circumferential direction of bowl cover 100.When bowl cover 100 screws gradually, projection can reduce the resistance that cup inner chamber gas is overflowed by air-vent 400, reduces the fluctuation of inner chamber air pressure.
In a word, the foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
