Detailed Description

The present invention will be further described with reference to the following specific embodiments.

Referring to the attached drawings, in the present embodiment, an insulation lunch box easy to screw and open a lid comprises a bottle body 1, an outer lid 2, an inner lid 3, a rotating disk 4 and a sealing rubber ring 5, wherein an outer thread is formed on an outer side wall of a mouth of the bottle body 1, and an inner thread connected with the outer thread is formed on an inner side wall of the outer lid 2. The inner cap 3 is fixedly connected to the top end of the inner wall of the outer cap 2, wherein the inner cap and the outer cap 2 of the present embodiment are fixedly connected by a preset screw (not shown), that is, the screw sequentially penetrates through the inner cap 3 and the outer cap 2 from bottom to top to realize the fixed connection therebetween.

In this embodiment, an annular rotary groove 31 is formed on the bottom end surface of the inner lid 3, wherein a plurality of limit protrusions are formed on the inner side wall of the annular rotary groove 31 and arranged in an annular shape, and each limit protrusion has a wedge-shaped structure.

In this embodiment, the top end surface of the rotating disc 4 is formed with a connecting portion 41 having an annular protruding structure, and the outer side wall of the connecting portion 41 is formed with an annular limiting groove 42 extending in an annular shape, so that the connecting portion 41 is embedded in the annular rotating groove 31, and the plurality of limiting protrusions 32 are matched and fastened with the annular limiting groove 42, so that the rotating disc 4 is connected to the inner cover 3, and the inner cover 3 does not limit the rotational freedom of the rotating disc 4, so that the rotating disc 4 embedded in the inner cover 3 can rotate along the annular rotating groove 31.

In this embodiment, a rubber ring groove 43 is formed on the outer circumferential surface of the rotating disc 4, and the rubber ring 5 is fitted into the rubber ring groove 43, so that the outer surface of the rubber ring 5 protrudes from the outer circumferential surface of the rotating disc 4 by fitting the rubber ring 5 into the rubber ring groove 43 in advance, and then the rotating disc 4 and the inner cover 3 are connected by fitting. At this time, a gap extending in a ring shape is formed between the outer surface of the seal rubber ring 5 and the inner side wall of the outer cover 2.

Further, the outer cover 2, the inner cover 3, the rotating disc 4 and the sealing rubber ring 5 are assembled to form a sealing cover structure of the heat-preservation lunch box, so that the sealing cover structure is in sealing fit with the bottle body 1.

When the outer cover 2 needs to be covered, the outer cover 2 is screwed to be rotatably connected to the bottleneck of the bottle body 1 (connected through a screw thread), the top end part of the bottleneck of the bottle body 1 is gradually embedded into a gap between the sealing rubber ring 5 and the outer cover 2, so that the rotating disc 4 is gradually embedded into the bottle body 1 (at this time, the sealing rubber ring 5 is gradually embedded into the bottle body 1 along with the rotating disc 4 and the sealing rubber ring 5 is contacted with the inner wall of the bottle body 1), at this time, due to the rotating matching mode adopted between the rotating disc 4 and the inner cover 3, when a user screws the outer cover 2 for sealing matching, the contact friction force existing between the sealing rubber ring 1 and the inner wall of the bottle body 1 plays a role in preventing the rotating disc 4 from rotating, so that the rotating disc 4 does not rotate in the process of screwing the outer cover 2 (in the actual process, the rotating disc 4 may possibly do a micro-rotation action when being just embedded into the, and then realized revolving to twist enclosing cover 2 and rotated gradually and moved down and drive rotary disk 4 and make vertical displacement action in step, finally after enclosing cover 2 is connected completely with body 1, sealed rubber ring 5 suit on rotary disk 4 is in body 1 bottleneck inner wall preforming and has sealed position 11 department to sealed rubber ring 5 and body 1 bottleneck inner wall are in sealing contact mutually, have realized the sealed effect to body 1 inner chamber.

When the outer cap 2 needs to be opened, a user rotates the outer cap 2 to gradually take the outer cap 2 off the bottle mouth of the bottle body 1, and in the process of rotating the outer cap 2, the rotating disc 4 cannot rotate due to the fact that the sealing rubber ring 1 is in friction contact with the inner wall of the bottle body 1, and the rotating disc 4 synchronously moves vertically upwards along with the rotating upwards movement of the outer cap 2, and finally after the outer cap 2 is completely separated from the bottle body 1, the rotating disc 4 is also separated from the bottle mouth of the bottle body 1, and the opening of the outer cap 2 is completed. Through such a mode, the problem that the traditional structure is difficult to open due to overlarge friction force between the sealing rubber ring 5 and the bottle body 1 in a high-temperature sealing state is effectively solved, the rotating action of the outer cover 2 is converted into the vertical action of the rotating cover 4, at the moment, the friction force between the sealing rubber ring and the bottle body is approximately in a vertical state with the vertical displacement of the sealing rubber ring, so that the friction force is approximately not worked, the influence of the friction force between the sealing rubber ring 5 and the bottle body 1 on the rotating action of the outer cover 2 is weakened, particularly, the influence on the outer cover 2 which is just screwed is reduced, the effect of easily opening the cover is achieved, and the use experience is greatly improved.

The above-described embodiments are merely preferred embodiments of the present invention, which are not intended to limit the present invention in any way. Those skilled in the art can make many changes, modifications, and equivalents of the embodiments of the invention without departing from the scope of the invention. Therefore, the content of the technical scheme of the utility model, according to the equivalent change made by the idea of the utility model, should be covered in the protection scope of the utility model.
