Beverage container

Abstract

A beverage container is provided. A decorative plate (21) which is basically in the shape of a flat plate is detachably mounted on the top surface of an outer cover (9) of the beverage container body (1), a metal part (45) is arranged in the decorative plate, the decorative plate is joined to the outer cover, the metal part is arranged between the outer cover and the decorative plate and then the outer cover and the decorative plate can be smelted and combined through electromagnetic induction heating. Therefore, the scratch caused by scratch and contact of a welding head during ultrasonic welding can be prevented. The metal part is annular in shape and can be peripherally combined with the outer cover and the decorative plate with high strength. The metal part is annular in shape and no gap is generated, so that high water tightness can be maintained. The operation of adding an embedding release member between an outer cover and a decorative plate during the conventional ultrasonic welding is not needed, so that an accommodating space (27) holding a heat insulation member (26) can be arranged spaciously.

Description

technical field [0001] The present invention relates to a container for beverages comprising a decorative plate. Background technique [0002] Conventionally, such beverage containers are known to include: a plug body that covers the upper opening of the container main body by combining ultrasonic waves and high-frequency components together; The spout at the position where the center of the top surface has been shifted, the cap that covers the outside of the spout in a liquid-tight manner, and the heat insulating material that is provided inside the plug body and protects the inside of the top surface, or A container for beverages in which an intermediate layer of a heat-insulating space and the like is sealed, and the sealing member and the plug body are welded in a liquid-tight manner on the outer edge side, and ultrasonic waves and high frequencies are used for the welding (for example, Patent Document 1) Wait. [0003] In addition, there is also a container for bevera...

AI Technical Summary

Problems solved by technology

[0006] In the case where ultrasonic waves are used to join members together in the manner of the beverage container of Patent Document 1 above, scratches occur due to contact between the horn and the jig of the ultrasonic welding device and the members.

[0007] On the other hand, in the case of using an adhesive to bond the decorative cover, sufficient bonding strength cannot be obtained

In addition, it is not easy to handle because the adhesive may go out of the range of use

[0008] In addition, once the sealing member etc. are put into the cover or the plug body, the space for putting the heat insulating material becomes narrow, and a sufficient heat insulating effect cannot be obtained.

[0009] Furthermore, since the screw thread of the cap or the plug body is often provided on the outside, it is difficult to make fitting and disengaging parts such as undercuts on the inside in terms of the structure of the mold.

In addition, although a structure in which padding is put inside is proposed in order to waterproof the above-mentioned method such as Patent Document 2, this requires not only an increase in the cost of the padding, but also a further increase in space.
