Abstract
A vacuum cup with the cover capable of being opened easily under any circumstances comprises a vacuum cup (3) and a vacuum cup cover (2) used together with the vacuum cup (3); an elastic soft piece (4) is arranged on the inner side of the vacuum cup cover (2) and positioned through a vertical periphery on the inner side of the vacuum cup cover; a hole (1) is formed at the top part of the vacuum cup cover (2); and the elastic soft piece (4) is made of rubber. The elastic soft piece (4) is arranged on the inner side of the vacuum cup cover (2), and the hole (1) is formed at the top part of the vacuum cup cover (2), so the air pressure between the elastic soft piece (4) and the hole (1) in the vacuum cup cover (2) is consistent with the external atmospheric pressure, which creates conditions for people to open the vacuum cup cover (2) from the vacuum cup (3) conveniently under any circumstances (without considering that whether the drinking water in the cup is hot or cold).
Description
Technical field:
The present invention relates to the thermos cup technology, especially related to the structure technology that under any circumstance can both easily open the thermos cup of heat-insulating cup cover.
Background technology:
The thermos cup of Chu Shouing in the market, after people pour boiling water into and cover heat-insulating cup cover, in case after the hot boiling water cooling in the thermos cup, will impel that the pressure of air reduces in the thermos cup (will less than or much smaller than the atmospheric pressure in the external world), cause heat-insulating cup cover to be difficult for being opened, cause the trouble in the use.
Summary of the invention:
The present invention's purpose is to propose a kind of thermos cup that changes existing behaviour in service.
In order to realize the present invention, intend adopting following technology:
It constitutes by thermos cup with the matching used heat-insulating cup cover of this thermos cup, it is characterized in that: be provided with the elasticity film in the inboard of heat-insulating cup cover, and this elasticity film is to locate by the vertical periphery of heat-insulating cup cover inboard, is provided with hole at the top of heat-insulating cup cover.---the above-mentioned elasticity film rubber that has drawn from.
The present invention's characteristics compared with the prior art: because the present invention is provided with the elasticity film in the inboard of heat-insulating cup cover, and be provided with hole at the top of heat-insulating cup cover, for under any circumstance (no matter its inner drinking water is terribly cold or awfully hot), the heat-insulating cup cover that people can easily open among the present invention has been created condition.
Description of drawings:
Fig. 1 has illustrated profile of the present invention (basic identical with prior art).
Fig. 2 has illustrated longitudinal sectional drawing of the present invention after pouring hot boiling water in the thermos cup into.
Fig. 3 has illustrated longitudinal sectional drawing of the present invention after the cooling of the hot boiling water in the thermos cup.
Symbol description
1: hole 2: heat-insulating cup cover 3: thermos cup 4: the elasticity film
The specific embodiment:
The present invention constitutes by thermos cup 3 with these thermos cup 3 matching used heat-insulating cup covers 2, it is characterized in that: be provided with elasticity film 4 in the inboard of heat-insulating cup cover 2, elasticity film 4 rubber that has drawn from, the thickness of this elasticity film 4 (for example: thickness is about 1 millimeter) can design very thinly.And, this elasticity film 4 is to locate (for example: adopt the bonding mode of nontoxic glue) by the vertical periphery of heat-insulating cup cover 2 inboards, be provided with hole 1 at the top of heat-insulating cup cover 2, the diameter of this hole 1 (for example: diameter is about 2 millimeters) can design very for a short time.
Using method of the present invention: when pouring boiling water in the thermos cup 3 into and covering heat-insulating cup cover 2, the elasticity film 4 on this heat-insulating cup cover 2 will inevitably be pressed to the top of heat-insulating cup cover 2 with it by the high-temperature gas below this elasticity film 4; And after the cooling of the boiling water in the thermos cup 3, the pressure of air reduces in the thermos cup 3, make the elasticity film 4 of the pressing to heat-insulating cup cover 2 tops originally direction retraction towards thermos cup 3 bottoms, above-mentioned elasticity film 4 reduces by the pressure of air in the deformation thermos cup 3 that suppressed (or slowing down).
Obviously, gas pressure between this moment heat-insulating cup cover 2 and the elasticity film 4, owing to be provided with the cause of hole 2, in above-mentioned use overall process, no matter the variation of water temperature how in the thermos cup 3, above-mentioned gas pressure all is identical with an atmospheric pressure in extraneous space, and at this moment, people just can start the top of heat-insulating cup cover 2 from thermos cup 3 like a dream.
Claims (2)
1. the thermos cup that under any circumstance can both easily open heat-insulating cup cover, it constitutes by thermos cup (3) with the matching used heat-insulating cup cover of this thermos cup (3) (2).
It is characterized in that:
Be provided with elasticity film (4) in the inboard of heat-insulating cup cover (2), and this elasticity film (4) is to locate by the inboard vertical periphery of heat-insulating cup cover (2), is provided with hole (1) at the top of heat-insulating cup cover (2).
2. the thermos cup that under any circumstance can both easily open heat-insulating cup cover as claimed in claim 1 is characterized in that: described elasticity film (4) rubber that has drawn from.
