Description

An easy-to-open packaging container

technical field

The invention relates to a beverage packaging container.

Background technique

The container cover in the prior art is connected to the container mouth by threads. When opening, the container cover needs to be unscrewed, which is troublesome to open. Especially, after the container cover is opened, the container mouth is wide open. On the one hand, the beverage in the container is easily contaminated. On the other hand, the liquid in the container is easy to spill.

Contents of the invention

In order to overcome the shortcomings of the prior art, the present invention provides a packaging container that is easy to open, simple in structure and has an automatic sealing function.

The technical solution adopted by the present invention to solve its technical problems is:

A packaging container that is easy to open, comprising a container, the container mouth of the container is connected with a container cover, and a sealing valve made of elastic material is installed between the end face of the container opening and the container cover, and the sealing valve is provided with The top of the container cover is provided with a closed broken part, and the part inside the broken part forms a cover, and the cover is provided with a support ring protruding downwards, and the projection of the support ring is located on the the end face of the container mouth.

The lip of the sealing valve is clamped between the end face of the container mouth and the bottom of the support ring.

The inner wall of the container cover is provided with a sealing ring, and a seal is formed between the sealing ring and the outer wall of the container mouth.

The top lower end of the container cover is provided with a sealing edge, and a seal is formed between the sealing edge and the sealing valve.

The mouth of the container is turned inwardly to form a supporting ring, and the sealing valve rests on the supporting ring.

The outer wall of the container mouth is provided with external threads, and the container cap is provided with internal threads matching the external threads.

The beneficial effects of the present invention are: a sealing valve is installed between the container mouth and the container cover of the present invention, the container cover is provided with a closed fracture part, and the part in the fracture part forms a surface cover. The method makes the container cover move down, the surface cover is separated from the broken part, and a water outlet is formed on the container cover. After opening, the cover cannot be restored, which can play an anti-theft role. When sucking or squeezing the container, the water outlet on the sealing valve is opened. The liquid in the container can flow out. In the natural state, the water outlet is closed to form a seal, so that the liquid in the container is kept hygienic. Even if the container is toppled over, the liquid in the container will not be spilled.

Detailed ways

Referring to Figures 1 to 5, a packaging container that is easy to open includes a container 1 and a container cover 3, the outer wall of the container opening 2 of the container 1 is provided with an external thread 12, and the inner wall of the container cover 3 is provided with a The external thread 12 matches the internal thread, and the container 1 and the container cover 3 are connected by threads. The top of the container cover 3 is provided with a closed broken part 6, and the part in the broken part 6 forms a cover 7, and the cover 7 is provided with a support ring 8 protruding downward, and the support ring 8 The projection is located on the end surface of the container mouth 2. When opening, the container lid is moved down by rotating or pressing down on the container lid, and the end surface of the container mouth 2 squeezes the support ring 8, so that the surface cover is broken along the fractured part, and the surface cover After breaking and separating, a water outlet is formed on the container cover, and the cover cannot be restored after opening, which can play an anti-theft function.

A sealing valve 4 made of elastic material is installed between the end face of the container mouth 2 and the container cover 3, and the edge of the sealing valve 4 is clamped between the end face of the container mouth 2 and the bottom of the support ring 8 Meanwhile, the container mouth 2 is flanged inward to form a support ring 11, and the sealing valve 4 rests on the support ring 11, which is simple and convenient to assemble. The sealing valve 4 is provided with a water outlet slit 5, referring to Figure 6 to Figure 10, in this embodiment, the number of the water outlet 5 can be one or more than one, and the shape of the water outlet 5 can be Arbitrary geometric shapes such as straight, arc or cross. When the face cover 7 falls off, the elastic action of the sealing valve 4 makes the water outlet slit 5 closed. When sucking or squeezing the container, the water outlet slit on the sealing valve is opened, and the liquid in the container can flow out. In the natural state, the water outlet slit The sealing forms a seal to keep the liquid in the container hygienic, even if the container is toppled over, the liquid in the container will not be spilled.

The top lower end of the container cover 3 is provided with a sealing edge 10, which forms a seal between the sealing edge 10 and the sealing valve 4 to prevent the liquid in the container from entering the container mouth and the threaded part of the container cover. The sealing edge 10 also It can limit the position of the sealing valve, so that the sealing valve is always close to the end face of the container mouth. The inner wall of the container cover 3 is provided with a seal ring 9, which forms a seal with the outer wall of the container mouth 2 to prevent body fluids entering the container mouth and the threaded part of the container cover from flowing out, and the sealing effect is good.
