Description

An upper cover of a heat preservation container

The invention relates to the field of thermal insulation containers, in particular to an upper cover of a thermal insulation container.

Insulation containers, such as thermos bottles or thermos cups, generally include two parts: the bottle cap and the container. The container is used to hold the food that needs to be kept warm or cold. The container adopts vacuum insulation or other technical means to block the heat exchange between the internal and external environment. . The bottle cap is screwed together and covers the opening of the container.

There are many kinds of bottle caps for conventional thermos bottles, and the basic structure generally has an outer cap and an inner plug. is separable. The bottom end of the inner plug also includes a ring seal made of rubber material, which can prevent the leakage of liquid food when the thermos is poured, and reduce the loss of food heat from the gap between the body and the inner plug.

In short, the bottle cap of the thermos bottle is divided into upper and lower cap ring bodies, the lower bottle cap ring body is a hollow tube body, and the inner bottom is formed with a screw rail that can be screwed with the top opening of the bottle body of the thermos bottle.

The function of the thermos bottle is to maintain the liquid in the bottle at high or low temperature for a long time. In addition to the function of screwing and closing, the function of the cap of the thermos bottle still needs to consider the airtightness to achieve the effect of long-term heat preservation. The tightness depends entirely on the quality of the gasket set on the bottle cap and the way of fitting with the bottle cap.

The improved structure of the thermos bottle cap proposed by the Republic of China Patent Publication No. TW 225769 is that a movable bottle stopper that can be moved up and down and rotated is set inside the bottle cap. When the bottle cap is screwed to the thermos bottle, the rotation and displacement of the movable bottle stopper promotes the protection of the bottle cap. The mouth of the warm bottle is tightly pressed against the leak-proof rubber ring, which can avoid the distortion, deformation, displacement and damage of the leak-proof rubber ring, and can effectively achieve the sealing effect for a long time.

The Republic of China Patent Publication No. M513659 U proposes an easy-to-clean thermos bottle cap. In order to divide the thermos bottle into a top cover body, an outer ring body and a column cover body, the outer ring body is in the shape of a hollow tube, and the top periphery is formed with a removable cover. The fitting groove is fitted with the flange on the top of the column cover. The column cover is in the shape of a hollow cup body. The inner periphery is provided with a guide screw rail. And the bottom and top rings are sleeved with airtight sealing rubber rings, and the center of the top cover body is protruded downward with a locking pipe column, which can be screwed with the guide screw rail on the inner periphery of the column cover body, through the top cover body, the outer ring body The cap body and the column cover can be twisted and unlocked with each other, so that the bottle cap can be disassembled, so that the inner concave of the twist lock part of the thermos bottle cap can be reduced, so as to achieve a practical creator that is easy to clean.

The Republic of China Patent Publication No. TW M513660 U proposes an easy-to-clean thermos bottle cap. In order to divide the thermos bottle into upper and lower cap ring bodies, the lower cap ring body is in the shape of a hollow tube, and an inner bottom is formed with a cap that can be connected with the bottle. The screw rail is screwed together with the opening on the top of the body, and the top of the screw rail is provided with a slope-shaped stopper convex body, and a guide screw rail is formed on the outside. The outer guide screw rail of the cap ring body is screwed together, and an elastic pressing button is arranged on the slope-shaped stop convex body opposite to the lower bottle cap ring body. There is an airtight rubber ring that can seal the inner surface of the top opening of the bottle body. The upper and lower bottle cap rings can be twisted and locked with each other and the elastic buckle can buckle and release the slope-shaped stopper convex body, so as to promote the bottle The cover can be disassembled, so as to reduce the concave degree and obstruction of the twist-lock part, thereby achieving a practical creator that is easy to clean.

Looking at the above-mentioned published patent cases, although the published patent TW 225769 is designed with an anti-leakage rubber ring, it is movably in a nested manner and the rotation and displacement of the movable bottle stopper pushes the mouth of the thermos bottle tightly against the anti-leakage rubber ring; Patents TW M513559 U and TW M513660 U mainly consider the practicability of the bottle cap being easy to clean.

However, considering the design of the above-mentioned published patent and the thermos currently disclosed on the market, the gasket provided on the cap will cause the cap to become negative due to, for example, the thermos is filled with hot water and then the water cools down, resulting in negative pressure. Difficult to open and easy to fall off after opening.

Based on the above reasons, it is very necessary to design an upper cover of the thermal insulation container that can withstand the deformation caused by the rise and fall of temperature, and will not cause the gasket to fall off due to thermal expansion and contraction.

In view of the above-mentioned shortcomings of the prior art, according to an embodiment of the present invention, an upper cover of a thermal insulation container is proposed, which includes: a cover body, which is a concave shell; an inner core, which is covered by a welding piece The utility model is combined and fixed in the upper cover; and a sealing ring is fastened to the welding piece through a plurality of tenon structures. Based on the above technical features, the bottle cap of the thermal insulation container provided by this creation takes into account the problems that the bottle cap is not easy to open due to the action of negative pressure and the sealing gasket falls off due to deformation. The design concept combines the welding pad to press and fix the ceramic core On the cover body and the sealing ring is fastened to the welding piece through the tenon method, so that the heat preservation container has the advantages that the bottle cap will not enter the water, not easy to get stuck, and the silicone sealing ring will not be loosened due to common negative pressure phenomenon.

In a preferred embodiment, the inner core is a cylindrical convex body.

In a preferred embodiment, the solder tab has an annular structure, which can be sleeved between the outer edge of the inner core and the inner edge of the cover body, and the annular structure is provided with a plurality of through holes.

In a preferred embodiment, the above-mentioned sealing ring has an annular structure and a plurality of tenons are arranged on the annular structure, and the plurality of tenons are fastened to the soldering piece through the corresponding plurality of through holes on the soldering piece.

In a preferred embodiment, the material of the cover body is polypropylene, the material of the inner core is ceramic, and the material of the soldering piece is polypropylene.

In a preferred embodiment, the material of the sealing ring is silicone.

In a preferred embodiment, the combination of the upper cover includes: arranging the inner core in the casing of the main body; using the solder tab to fit the inner core so that the inner core is pressed into the casing of the upper cover, The welding piece and the upper cover are quickly rubbed by ultrasonic waves. After frictional heat is generated, the polypropylene material of the welding piece and the body will melt, and the welding piece will firmly fix the inner core in the casing of the upper cover.

In a preferred embodiment, the rear end of each of the plurality of tenons has a barb structure.

In a preferred embodiment, the inner side of the concave shell of the main body is provided with a screw rail for screwing with the heat preservation container.

In a preferred embodiment, the annular structure of the sealing ring and the opposite side where the plurality of tenons are arranged are flat surfaces and include an ear structure.
