Abstract
The utility model discloses a vacuum cover and a heat preserving cup with the vacuum cover. The vacuum cover comprises a cover body and is composed of an outer cover and an inner cover. The outer cover is a hollow cylinder with one open end. The inner cover is a hollow cylinder with one open end, and the diameter of the inner cover is smaller than that of the outer cover. The inner cover is sleeved with the outer cover. The open end of the inner cover is in sealing connection with the open end of the outer cover. The vacuum cover further comprises a threaded body formed by forming threads on the inner side wall of a tube body provided with two open ends. The outer side wall of the threaded body is coaxially and fixedly matched with the outer side wall of the inner cover. The vacuum cover solves the technical problems that a vacuum cover in the prior art is not reasonable in structure, and is not closely matched with a cup body so that the cup body matched with the vacuum cup is not good in heat preserving effect. The vacuum cover can be closely matched with the cup body. The utility model further provides the heat preserving cup with the vacuum cover.

Chinese patent literature CN101627882A discloses a kind of retractable double-layer vacuum cup, formed by cup shell, cup inner casing, bowl cover, be provided with scalable cup inner casing in the cup inner casing, be provided with the Telescopic cup body case between cup shell, cup inner casing, the bowl cover upper shield is on the Telescopic cup body case.
although the bowl cover in the described retractable double-layer vacuum cup of above-mentioned patent documentation is also vacuum structure, but the threaded portion that it coordinates with cup and described bowl cover are integrally formed, therefore, the structure of above-mentioned bowl cover makes no matter the female thread structure on it is to form the space with other parts after moulding to vacuumize or reshaping female thread structure after bowl cover vacuumizes again, the capital is out of shape this female thread structure to some extent, thereby cause the female thread structure on described bowl cover to coordinate not tight with helicitic texture on described cup, liquid in thermos cup is flowed out, and can affect the integral heat insulation effect of vacuum cup.
The utility model content
For this reason, technical problem to be solved in the utility model is that vacuum cover structure of the prior art is unreasonable, vacuum cover coordinates not tight with cup, cause the cup heat insulation effect that is mated bad, and then provide a kind of and coordinate vacuum cover closely with cup, and has the thermos cup of described vacuum cover.
For solving the problems of the technologies described above, a kind of vacuum cover of the present utility model comprises lid, is comprised of enclosing cover and inner cap, and described enclosing cover is the hollow circular cylinder of an end opening; Described inner cap is that diameter is less than the hollow circular cylinder of described enclosing cover and an end opening, described inner cap and described enclosing cover fit, the openend of described inner cap and the openend of described enclosing cover are towards identical and be tightly connected, also be included in the threaded threaded body that is shaped on the madial wall of body of both ends open, the lateral wall of described threaded body and the coaxial secure fit of the lateral wall of described inner cap.
Described inner cap middle part also is formed with the protuberance that extends to its openend, and the diameter of described protuberance is less than the diameter of described threaded body.
Described protuberance is cylindrical.
Also be fixedly installed sealing ring on described protuberance.
Described sealing ring is silica gel ring.
Described threaded body is plastic material.
Described enclosing cover blind end is formed with recess, is provided with the silica gel moccasin on described recess.
Described inner cap and described enclosing cover are stainless steel.
The thickness of described inner cap and described enclosing cover is 0.4mm.
Thermos cup with above-mentioned vacuum cover, comprise an end opening the vacuum cup and with the vacuum cover of described cup threaded engagement, described protuberance diameter is less than the diameter of described opening.
Technique scheme of the present utility model has the following advantages compared to existing technology,
(1) in vacuum cover described in the utility model, also be included in the threaded threaded body that is shaped on the madial wall of body of both ends open, the lateral wall of described threaded body and the coaxial secure fit of the lateral wall of described inner cap, be that lid and helicitic texture are to separate moulding, therefore lid can the double thread structure not have any impact when forming vacuum body, guarantee that vacuum cover described in the utility model is coordinating with cup closely, high insulating effect.
(2) in vacuum cover described in the utility model, described inner cap middle part also is formed with the protuberance that extends to its openend, the diameter of described protuberance is less than the diameter of described threaded body, be formed with annular groove between the inner cap sidewall that namely coordinates with enclosing cover and protuberance, being suitable for described protuberance extends in cup and the inner cap sidewall that coordinates with enclosing cover coordinates with the cup external screw thread, this setting has not only increased the vacuum space, has improved the heat insulation effect of bowl cover, has also saved the space that coordinates.
(3) in vacuum cover described in the utility model, described protuberance is cylindrical, coordinates with the rim of a cup of cup.
(4) in vacuum cover described in the utility model, also be fixedly installed sealing ring on described protuberance, preferred described sealing ring is silica gel ring, the heat insulation effect of the container that further assurance coordinates with bowl cover.
(5) in vacuum cover described in the utility model, described enclosing cover blind end is formed with recess, is provided with the silica gel moccasin on described recess, can be shaped on the silica gel moccasin very easily various patterns or trade mark, and just product is more attractive in appearance.
