Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a portable liquid thermal container.

Generally speaking, this type of liquid heat insulating container has a cap placed over the top end of the container body, and is used for drinking or drinking by pouring tea or other liquid inside the container into the cap when outdoors, etc. However, when the outer circumferential surface of the container body is made of metal, it is necessary to provide the container body with a shoulder member for screwing the tip.

However, in this case, there is a risk that the shoulder member may rotate together and loosen or fall off when the screws are attached or removed, and a complicated mounting structure must be used to prevent this. Since the member may fall off due to the pulling force of the hanging string, a problem arises in that a separate attachment member for attaching the hanging string must be provided.

In view of the above-mentioned problems, the object of the present invention is to provide a liquid heat-insulating container that has a simple structure and has a shoulder member attachment structure that does not rotate together when the screws are attached and detached, and that allows the suspension string to be securely attached. In order to achieve this purpose, the container body 1 is constructed by making both the liquid container 6 serving as the inner peripheral surface and the outer case 7 serving as the outer peripheral surface made of metal, and creating a vacuum between them. A shoulder member 1 made of synthetic resin having a side screw 16 into which the tip 3 is screwed into the shoulder portion of the outer case 7.
3, and the shoulder member 13 is provided with a detent portion 19 that is coupled to the shoulder portion of the outer case 7 by screwing or engaging, and the shoulder member 13 is attached to the shoulder portion 7a of the outer case 7. Forcibly fit,
This forced fit is characterized by integrally molding the suspension string attachment part 18 at a position of the shoulder member 13 corresponding to the position.
