Detailed ways

The specific embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the utility model, and are not intended to limit the utility model.

In the present utility model, unless otherwise stated, the used orientation words such as "up, down, left, right" usually refer to the directions shown in the accompanying drawings.

Example 1

This embodiment provides a portable fresh-keeping cup set, as shown in Figure 1, the portable fresh-keeping cup set includes a cover body 1 and a tank body 2, the cover body is movably connected to the tank body, and more than one The airtight ring convex 41, above the airtight ring convex is provided with a safety hook 61 combined with the outer wall of the cover through the thin connecting part 44, and a ring-shaped connecting pipe 3 is extended downward on the inner bottom of the closed end 11 of the cover body, and the length of the connecting pipe is Greater than or equal to the height of the cover, the top edge of the tank is provided with a ring-shaped folded portion 202, and the top surface of the folded portion is integrally connected with an upward puncture needle 203, and the bottom edge of the cover is combined with the sealing film 101 by pasting The top surface of the folded portion 202 of the tank body is bonded to the barrier film 201 by pasting, and storage spaces are formed between the sealing film and the cover body and between the barrier film and the tank body.

In this embodiment, the sealing film and the barrier film are made of various materials such as plastic diaphragms or airtight paper diaphragms, and edible wax or Low temperature heat seal coating for sealing. The barrier film and the top plane of the folded part of the can body are sealed by edible wax or low-temperature heat-sealing paint. Therefore, the beverage in the cover body can be avoided from being in contact with the outside air, and can effectively prevent the tea leaves, dried fruits and vegetables, Chinese herbal medicines, enzymes and concentrated vinegar from getting damp and changing taste in the tank body.

Described turning over part 202 is arranged on the outside of tank body 2 top edges, and the edge of turning over part 202 extends upwards and establishes an annular surrounding piece 43, and surrounding piece 43 is screw-locked and combined in lid body 1, and the height of described surrounding piece is 5mm. The airtight ring protrusion 41 is a 5-turn spiral ring protrusion continuously wound on the outer wall of the lower part of the cover body 1, and the thread pitch is 1mm. The distance from the upper end of the pricker 203 to the top edge of the surrounding sheet 43 is 2mm less than the height of the surrounding sheet, that is, the height of the pricker is 3mm.

When in use, the screw lock of the cover body 1 is combined on the tank body 2, so that 3 circles of airtight rings protrude above the top edge of the tank body 2, and then the hook tongue of the safety catch 61 is stopped against the top edge of the tank body, which can Prevent the tank body 2 from continuing to rotate and move upwards, so that the needles can pierce the sealing film. When the consumer wants to mix the objects in the cover 1 with the objects in the tank, the barrier film 201 is torn off, and the safety hook 61 is flipped up, and the cover 1 is screw-locked to the tank 2, and the cover Body 1 is screwed down, because the pricker 203 is located at the tank body 2 folded portion and is close to the inner wall of the surrounding sheet 43, and the deformation of the sealing film near the inner wall of the lower bottom edge of the lid is small, ensuring that the pricker punctures the sealing film smoothly.

When turning the cover like this, the cover drives the pricker 203 to cut the sealing film, and the opening of the sealing film is roughly circular, as shown in Figure 2. When the pricker rotates close to one circle, because the middle part of the sealing film has lost support, the sealing of the middle part The film is still integrated with the sealing film at a certain position on the periphery, so it will not fall into the water bottle. Before the safety hook 61 is turned over, the distance between the top of the needle and the sealing film is 2 mm, and before the safety hook 61 is turned over, there is a distance of 3 mm between the sealing film and the top surface of the folded part 202 of the tank body 2, and the distance It is equal to the height of the needle; the thread pitch between the internal thread section of the surrounding sheet 43 and the outside of the cover body is 1mm. In this way, the needle can theoretically rotate three times to ensure that the needle can cut the sealing film.
