Description

Closely-assembled heat insulation cup cover

Technical Field

The invention relates to the technical field of daily article accessories, in particular to a tightly assembled heat insulation cup cover.

Background

To a certain extent, the quality of the heat insulation effect of heat insulation containers such as the vacuum cup mainly depends on whether the side wall of the vacuum cup has a good heat insulation effect or not. For example, the cup may be provided in the form of an insert, and preferably a vacuum is drawn within the insert. However, in practical use, the cover of the vacuum cup can greatly influence the heat preservation effect if the heat preservation effect is not good enough. Especially, heat is easily dissipated from the middle of the cap relatively quickly and much because the middle of the cap is often of a single-layer, one-component construction. Some manufacturers also perform heat insulation treatment on the cover, but the effect is not ideal enough or the structure tends to be complicated. And, the components of the lid are not easily assembled compactly, and bacteria are easily grown inside.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a tightly assembled heat insulation cup cover which has the characteristics of good heat insulation effect and compact assembly.

In order to achieve the purpose, the invention adopts the technical scheme that: the closely-assembled heat-insulating cup cover comprises a cylindrical cover body, wherein the lower part of the cover body is provided with an opening, the upper part of the cover body is sealed so as to be provided with a top part, a connecting part is arranged on the inner circumferential side wall of the cover body, the connecting part is an internal thread or a buckle, the middle part of the top part is sunken downwards to form a cylindrical upper sunken cavity with an upward opening, a gap is reserved between the outer circumferential side wall of the upper sunken cavity and the inner circumferential side wall of the cover body, meanwhile, the middle position of the bottom part of the upper sunken cavity is sunken upwards to form a cylindrical lower sunken cavity with a downward opening, the heat-insulating cup cover also comprises a heat-insulating sleeve, the heat-insulating sleeve comprises an upper opening, a lower closed cylinder and an upper open-upper closed cylinder, the outer circumferential side wall of the upper cylinder is connected to the inner circumferential side wall of the upper opening of the lower cylinder in a sealing fit manner, and the outer circumferential side wall of, and the outer diameter of the lower cylinder is larger than the inner diameter of the lower concave cavity.

The bottom of the lower cylinder protrudes downward outside the lower portion of the lower concave chamber.

And a sealing ring is sleeved on the part of the outer part of the lower cylinder, which is positioned at the outer side of the lower part of the lower sunken cavity.

And vacuumizing the lower cylinder.

And a vacuumizing port is arranged in the middle of the upper cylinder.

After adopting the structure, compared with the prior art, the invention has the advantages that: the heat preservation effect preferred, and the assembly is comparatively compact. According to the tightly assembled heat insulation cup cover, the heat insulation sleeve is arranged in the middle of the cover body, and the heat insulation sleeve is provided with the vacuum cavity after being optimized, so that the phenomenon that heat is excessively quickly and excessively dissipated from the middle of the cover body which is easy to run off can be avoided, and a good heat insulation effect is ensured. Meanwhile, the outer diameter of the lower cylinder is slightly larger than the inner diameter of the lower sunken cavity, so that the lower cylinder and the lower sunken cavity can be combined very tightly, steam is not easy to enter a combining part and the inside of a component, and the cup cover is sanitary in use.

Drawings

The invention is further illustrated with reference to the following figures and examples:

FIG. 1 is a front cross-sectional view of a close-fitting insulated cup cover of an embodiment of the present invention;

fig. 2 is a view of fig. 1 in an exploded state.

Detailed Description

Examples, see fig. 1 and 2: the closely assembled heat insulation cup cover comprises a cylindrical cover body 10. The lid body 10 is open at a lower portion and closed at an upper portion to have a top portion 11. The inner circumferential sidewall of the cover 10 is provided with a connecting portion 12, and the connecting portion 12 is an internal thread or a snap. That is, the cover 10 may be screwed or engaged with an upper opening of a corresponding container such as a thermos cup. Generally, the cover 10 is made of plastic.

Further speaking:

the top 11 is formed with a cylindrical upper recess 111 recessed downward at the center and opened upward. A gap 30 is provided between an outer circumferential sidewall of the upper concave chamber 111 and an inner circumferential sidewall of the cover body 10. The gap 30 is intended for access to the upper part of a container such as a thermos cup. Meanwhile, the middle position of the bottom of the upper concave cavity 111 is upwards concave to form a cylindrical lower concave cavity 112 with a downward opening.

The close-fitting insulated cup lid also includes an insulating sleeve 20. The sleeve 20 includes an open-topped, closed-bottomed lower cylinder 21 and an open-topped, closed-bottomed upper cylinder 22. The outer circumferential side wall of the upper cylinder 22 is sealingly engaged with the inner circumferential side wall of the upper opening of the lower cylinder 21. That is, the outer diameter of the upper cylinder 22 should be the same as the inner diameter of the lower cylinder 21, and the outer circumferential side wall of the upper cylinder 22 may be fixed to the inner circumferential side wall of the lower cylinder 21 by means of bonding or the like.

More specifically:

the outer circumferential sidewall of the lower cylinder 21 is caught on the inner circumferential sidewall of the lower concave cavity 112, and the outer diameter of the lower cylinder 21 is larger than the inner diameter of the lower concave cavity 112. Generally, the outer diameter of the lower cylinder 21 is 0.05-0.1 mm larger than the inner diameter of the lower concave cavity 112. In order to achieve the above assembling effect, in the manufacturing process, the heat insulation sleeve 20 is firstly prepared, then the cover body 10 is manufactured in an injection molding manner, after the injection molding is completed, the cover body 10 which is not completely cooled is taken out as fast as possible, the lower cylinder 21 of the heat insulation sleeve 20 is clamped in the lower concave cavity 112, and after the cover body 10 is completely cooled, the heat insulation sleeve 20 and the cover body 10 can be assembled together very tightly.

Therefore, the heat insulation sleeve 20 reduces the excessive loss of heat in the middle of the cover body 10, and the cover body 10 and the heat insulation sleeve 20 are assembled more tightly, so that the cup cover has a compact structure and is more sanitary in use.

Optimizing:

the bottom of the lower cylinder 21 protrudes downward outside the lower portion of the lower concave chamber 112. Namely, the lower cylinder 21 also has the function similar to an inner cup cover, thereby further reducing heat loss and enhancing the sealing effect on the vacuum cup.

The portion of the exterior of the lower cylinder 21 outside the lower portion of the lower recessed cavity 112 is fitted with a seal ring 40. That is, the sealing effect is further enhanced and the packing 40 is easily assembled.

And (4) continuing optimization:

a vacuum is drawn in the lower cylinder 21. The upper cylinder 22 has a vacuum port 221 at the center. Of course, after the vacuum is drawn, the vacuum port 221 is sealed. Thus, the heat preservation effect is better, and the vacuum-pumping port 221 is not easy to leak after being sealed.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
