Description

Heat-preservation water cup comprising radial sealing device

Technical Field

The utility model relates to a cup seal, in particular to a heat-preservation cup comprising a radial sealing device.

Background

In the prior art, the cup is generally provided with the sealing ring on the cup cover, the cup cover is screwed, the sealing ring in the cup cover is pressed on the end surface of the cup mouth, the structure is simple, the production cost is low, the cup is widely applied, particularly, the vacuum cup or the vacuum bottle adopting the axial sealing technology is adopted, in order to achieve a better heat preservation effect, the sealing effect of the vacuum cup or the vacuum bottle is also continuously improved, when the internal water temperature is gradually reduced, the negative pressure is generated inside the vacuum cup or the vacuum bottle and is gradually increased, the vacuum cup or the vacuum bottle can be opened by large force when the cup cover or the bottle cover is opened, and great inconvenience is.

In prior art, in order to solve above-mentioned problem, set up the less gas vent of diameter on bowl cover or bottle lid mostly, when thermos cup or thermos bottle are opened to needs, will open the gas vent earlier and get rid of inside negative pressure, then can be more convenient open bowl cover or bottle lid, but adopt this kind of technical scheme to exist, A causes the heat preservation effect decline of thermos cup or thermos bottle, and B bowl cover and bottle lid structure are complicated, and the big manufacturing cost height of the complicated preparation degree of difficulty of technology.

SUMMERY OF THE UTILITY MODEL

In view of this, the main object of the utility model is to provide a heat preservation drinking cup including radial seal device, through this technical scheme, adopt radial seal circle to seal, utilize the lower elasticity interference seal face of radial seal circle, reach balanced sealed, need not set up the gas vent again, not only can be better reach the sealed effect of heat preservation to simple structure, production cost of manufacture is low, convenient application.

In order to achieve the above purpose, the technical solution of the present invention is realized as follows: the utility model provides a drinking cup that keeps warm including radial seal device, includes cup and bowl cover, the bowl cover inboard is provided with interior screw thread, the rim of a cup outside of cup is provided with outer screw thread, on the rim of a cup outside of bowl cover spiral dress on the cup, still include boss, bulge loop and radial seal circle, the boss sets up at bowl cover inner bottom intermediate position, and the bulge loop is fixed on the boss lateral wall to radial outside arch, and radial seal circle supports for cyclic annular suit on the bulge loop, and radial seal circle's the outside supports and presses on the rim of a cup inner wall of cup.

As a further technical scheme, an inner clamping groove is formed in the inner side face of the upper portion of the radial sealing ring, and the inner clamping groove of the radial sealing ring is sleeved on a convex ring of the cup cover.

As a further technical scheme, the cross-sectional shape of the radial seal ring is like a number '3', an upper convex upper seal surface is arranged at the upper part of the outer side surface of the radial seal ring, a gap is reserved between the upper seal surface and the inner wall of the cup opening of the cup body, a lower elastic interference seal surface which is arched outwards is arranged at the lower part of the outer side surface of the radial seal ring, a gap is reserved between the upper seal surface and the inner wall of the cup opening of the cup body, and the outer edge of the lower elastic interference seal surface is pressed against the inner wall of the cup opening of the.

The beneficial effect after adopting above-mentioned technical scheme is: the utility model provides a thermal insulation drinking cup including radial seal device, through this technical scheme, need not set up the gas vent again, not only can be better reach the sealed effect of heat preservation to simple structure, the production cost of manufacture is low, convenient application.

Drawings

Fig. 1 is a schematic overall sectional structural view of the present invention.

Fig. 2 is a partial enlarged view of fig. 1 taken along line K.

In the figure, a cup body 1, a cup cover 2, a cup mouth 3, an inner screw thread 4, an outer screw thread 5, a boss 6, a convex ring 7, an inner clamping groove 8, an upper sealing surface 9 and a lower elastic interference sealing surface 10.

Detailed Description

The following description will explain embodiments of the present invention in further detail with reference to the accompanying drawings.

As shown in fig. 1-2, the utility model relates to a heat preservation drinking cup including radial sealing device, including cup 1 and

bowl cover

2, 2 inboards of bowl cover are provided with

interior screw thread

4, 3 outsides in the rim of a cup of cup 1 are provided with

outer screw thread

5, 2 soon adorn on 3 outsides in the rim of a cup on cup 1 of bowl cover, still include boss 6, bulge loop 7 and radial seal circle, boss 6 sets up at 2 inner bottom intermediate positions of bowl cover, and bulge loop 7 is fixed on 6 lateral walls of boss to the outside arch of footpath, and radial seal circle is cyclic annular suit on bulge loop 7, and the outside of radial seal circle is supported and is pressed on 3 inner walls in the rim of a cup of cup 1.

As a further embodiment, the inner side surface of the upper part of the radial sealing ring is provided with an inner clamping groove 8, and the inner clamping groove 8 of the radial sealing ring is sleeved on the convex ring 7 of the cup cover 2.

As a further embodiment, the cross-sectional shape of the radial seal ring is like a number "3", an upper portion of an outer side surface of the radial seal ring is provided with an upper seal surface 9 protruding outward, a lower portion of the outer side surface of the radial seal ring is provided with a lower elastic interference seal surface 10 protruding outward, a gap is formed between the upper seal surface 9 and an inner wall of the cup opening 3 of the cup body 1, and an outer edge of the lower elastic interference seal surface 10 abuts against an inner wall of the cup opening 3 of the cup body 1.

In the application of the utility model, when the pressure in the cup is positive, the pressure in the cup presses the inner side of the lower elastic interference sealing surface 10 of the radial sealing ring, thereby forcing the outer edge of the lower elastic interference sealing surface 10 to be more tightly attached to the inner wall of the cup mouth 3 and achieving better sealing effect; when the cup cover 2 is opened when the pressure in the cup is negative pressure, the cup cover 2 is rotated, external air passes through a gap between the inner screw thread 4 and the outer screw thread 5, penetrates through a gap between the upper sealing surface 9 and the inner wall of the cup opening 3, and is pushed open under the action of pressure, the lower elastic interference sealing surface 10 sucks the air into the cup, so that the pressure in the cup is the same as the external pressure, and the purposes of saving an exhaust port and conveniently and easily opening the cup cover 2 are achieved.

The embodiment of the utility model provides an in, in order to guarantee that the drinking cup accords with the food hygiene requirement, radial seal adopts food level silica gel material to make.

The utility model adopts the technical proposal that the heat-preservation cup is used on a heat-preservation cup and can be arranged on the sealing of a heat-preservation bottle or other heat-preservation products according to the requirement.

The above description is only a preferred and practical embodiment of the present invention, and is not intended to limit the scope of the present invention.
