Description

Technical Field

[0001] The present invention relates to the technical field of food containers, and more specifically, to an instant sealed container made of plastic material. Background Art

[0002] There are various beverage cups, coffee cups, milk tea cups, etc. on the market. When used for takeout or production, they usually need to have lids, which must have good sealing properties to prevent the liquid inside from leaking out and affecting drinking and carrying.

[0003] Meanwhile, there are many designs for beverage cup lids. The most common ones are provided with a straw insertion hole and an air hole on the cup lid, and then a straw is inserted into the cup body for drinking, or a closable and openable drinking opening is formed on the cup lid, and when drinking, the drinking opening is directly opened to drink.

[0004] However, the cup and the lid are locked together to achieve a good seal, but after all, it is only locked together, and it is easy to be affected by external pressure and cause the lid to separate from the cup, so that the liquid leaks out, affecting drinking and carrying, and is not suitable for batch transportation. The existing technology uses a membrane and the outer edge of the upper surface of the cup for heat sealing to solve the above problems. For example, patent CN212830159U discloses a paper cup lid, a self-sealing paper cup and a self-sealing paper bowl. However, due to the use of paper membrane, when drinking, after drinking directly through a straw inserted, if it cannot be drunk all at once, it will not be able to recover to a sealed state that is convenient for carrying. If there is a large bumpy amplitude or it is squeezed by external force, there will be a possibility of leakage, and the food in the cup is easily spoiled because it is connected to the outside world through the straw. Therefore, it is necessary to develop a process or material so that it can solve the above problems while reducing costs and simplifying the process. Summary of the invention

[0005] In view of this, in order to solve the above-mentioned problems, the present invention proposes a plastic instant sealed container, comprising a cover body 10 and a cup body 20, wherein the cover body 10 and the cup body 20 both have an open edge 40 and a closed distal end, a liquid outlet 30 is provided at the closed distal end of the cover body 10, and a sealing cover that can be opened and closed and sealed multiple times is provided at the liquid outlet 30, the cup body 20 is used to store the prepared food, when the cup body 20 stores the prepared food, the edges 40 of the cover body 10 and the cup body 20 are connected and sealed, so that the cover body 10 and the cup body 20 form a whole, avoiding the cover body 10 from being separated from the cup body 20 due to external pressure, and the food in the cup body 20 can be repeatedly eaten by opening and closing the sealing cover, so that the food can be sealed and stored, which is convenient to carry and transport, the main bodies of the cover body 10 and the cup body 20 are both made of plastic material, and the main body of the cover body 10 is formed by injection molding, with a simple manufacturing process and low cost.

[0007] Furthermore, the main body of the cup body 20 is formed by injection molding or vacuum molding.

[0008] Furthermore, when the main body of the cup body 20 is formed by vacuum forming or injection molding, in-film labeling can be performed first, and then vacuum forming or injection molding can be performed.

[0009] In some embodiments, the edge 40 is a folded edge extending to the outside of the main body of the cover body 10 and the cup body 20, and the folded edges extending to the outside of the main body of the cover body 10 and the cup body 20 are contacted and connected and sealed.

[0010] Furthermore, the method of connecting and sealing the edge 40 of the cover body 10 and the cup body 20 includes: heat sealing, welding, bonding, and ultrasonic.

[0011] Furthermore, the main bodies of the cover body 10 and the cup body 20 are multi-layer or single-layer structures. The multi-layer structure can use different types of plastics in different layers to obtain better performance, or lower cost, or different colors for each layer.

[0012] In some embodiments, the vertical section of the main body of the cup body 20 is rectangular or conical. The vertical section of the main body of the cup body 20 is conical, which is easy to stack and occupies little space. At the same time, the diameter of the upper open part is larger than the diameter of the lower closed distal end, which makes it convenient to put freshly prepared food into the cup body 20.
