Description

Sealed tank structure with exhaust function

This creation is related to the sealed can, especially refers to a kind of gas generated from the food material, which is discharged out of the can body through an exhaust valve, so that the food material (in particular, the garlic and the shallot) maintains a fresh structure.

In general, sealed cans can be used to isolate the space inside the tank from the outside air. Therefore, it has a certain effect on preserving food or other items that need to be insulated from air, and it is economical because the price of the sealed can is not expensive. Therefore, it is quite widely accepted by the public.

However, ingredients such as garlic and coffee beans are not suitable for being placed in sealed cans. The reason is that these materials will naturally emit carbon dioxide and other gases after being shelled and baked, which will cause the inner space of the can to expand and the sealed cans to be broken. The problem has occurred.

In addition, when products such as garlic are placed in a sealed can, the garlic may germinate or become too moist to cause deterioration in a viable environment (with sufficient oxygen, humidity, and temperature). Therefore, some manufacturers will prevent the germination of garlic by using inhibitors and other items on the garlic. However, these inhibitors are not refined by natural substances, so harmful substances remain on the garlic, and there is concern about food safety. Therefore, it is necessary to improve the conventional sealed cans.

The main purpose of the present invention is to provide a sealed can structure having an exhaust function, in which a cover is provided with two exhaust holes, and a one-way exhaust valve is assembled in the exhaust hole, according to which The gas in the tank is discharged through the exhaust valve to maintain the effect of keeping objects inside the tank fresh.

The structure that can achieve the above object mainly comprises: a tank body, a bottle cap and a one-way exhaust valve; the tank body has a can body and a tank mouth, and the tank body has a receiving groove in the center thereof. a can opening is formed at a top edge of the container, and the can end has a tapered combination portion with the can body; the bottle cap is formed of a soft plastic material, and the bottle cap is provided with a top plate and a ring wall. The top plate can define a top surface and a bottom surface, the ring wall is disposed on the bottom surface, the ring wall can be fastened to the combination portion, and the bottle cap is provided with more than one vent hole in the center; the one-way The exhaust valve is formed by a cover body, a rubber pad and a top support column from the outside to the inside. The bottom of the cover body is provided with a plurality of through holes, and the rubber pad is connected with the top support column shaft. a cover is disposed on the vent hole; a top end of the cover body is disposed; and the one-way exhaust valve is assembled on the bottom surface of the bottle cap through the above structure, and the cover body can directly shield the vent hole The cap is tightly connected to the ring wall at the can end of the can body to reach the cap and the cap is closed; When there is a pressure difference between the gas, the gas pushes the rubber pad through the vent hole of the cover body to discharge the gas of the can body from the vent hole, and the internal and external pressures are balanced, and when the gas is released, the top support column is The gravity rebounds the silicone pad to cover the venting hole, preventing gas outside the can body from flowing into the cavity of the can body, preventing the contents of the can body from deteriorating and prolonging the storage period.

In some embodiments, the cap and the one-way exhaust valve are subjected to high-frequency processing such that the planar end of the one-way exhaust valve is integrated with the bottom surface of the cap.

In some embodiments, the cap is coupled to the one-way venting valve through a food grade adhesive such that the planar end of the one-way venting valve is integral with the bottom surface of the cap.

In some embodiments, the top support column is further fitted with an elastomer to achieve a positive reset of the silicone pad.

The aforementioned elastomer may be a sponge, a rubber elastic column or a spring.

In some embodiments, a joint of the ring wall of the cap and the bottom surface, and a joint of the ring wall and the can end are respectively provided with an airtight rubber ring to increase the airtight effect.

Through the above structure, the functions that this creation can provide are briefly described as follows:

1. By providing a one-way exhaust valve on the bottle cap, when the gas in the tank body generates gas and the air pressure inside the tank body changes, the gas is vented by the one-way exhaust valve to maintain the pressure inside and outside the tank body. Balanced, can prevent the object from deteriorating during extended storage.

2. The one-way exhaust valve can balance the pressure difference of the tank body, and can prevent outside air from entering the tank of the tank body, preventing the outside air and moisture from causing an environment suitable for growth in the tank body. .
