Description

[Detailed explanation of the invention] This invention relates to a thermos flask, and more specifically, to the mounting structure of the handle.

The handle attachment structure of this kind of thermos flask is
The product described in Publication No. 122435 has been filed as a prior application for utility model registration.

In this device, a bottom flap having a protruding piece is interposed between the lower inner wall of the exterior body and the bottom member, and the protruding piece, the exterior body, and the handle end are connected with a screw from inside the protruding piece. This is what happens.

However, in this case, the three types of screws for fixing the protrusion of the bottom flap, the exterior body, and the end of the handle are done from inside the protrusion of the bottom flap, which has the disadvantage that the screw fixing work is troublesome.

In this invention, the screw receiver that contacts the exterior body at the end of the handle has an extended shape, and the screw receiver has a part that corresponds to the protruding piece of the bottom flap through the exterior body. The present invention provides a thermos flask which eliminates the above-mentioned disadvantages and prevents the handle from wobbling by screwing the exterior body and the projecting piece together from the outside with screws.

An embodiment of this invention will be described below with reference to FIGS. 1 and 2.

Reference numeral 1 denotes a thermos bottle body, and the figure shows an example of a tilt-type thermos flask in which the handle 2 is gripped and the contents are poured out by tilting it toward the spout 3 side. It consists of an exterior body 5 made of steel plate, a bottom member 9, and an inner bottle 13.

A seam part 6 is formed at the rear of the exterior body 5, and a hemline part 5a is formed at the lower end. A bottom flap 8 having a female threaded portion 7 and a protruding piece 17 formed on the upper end thereof is fitted into the bottom flap 8. The male threaded portion 10 of the bottom member 9 is screwed into the female threaded portion 7 of the bottom flap 8, and the bottom member 9 is attached to the bottom flap. It is connected to 8.

That is, the bottom flap 8 is interposed between the lower inner wall of the exterior body 5 and the bottom member.

An inner cylinder part 12 having a female threaded part 11 is protruded from the center of the bottom member 9, and a male thread of a protective cylinder 14 that protects the tip 13a of the medium bottle 13 and holds the bottle bottom is attached to the female threaded part 11. The portion 15 is screwed together.

16 is a rotating body for rotating the thermos bottle body 1, and 4 is a stopper that closes the mouth of the medium bottle 13.

At one end of the handle 2, a screw receiver having an appropriate shape such as a rectangular, semicircular, or circular shape that comes into contact with the exterior body 5 has an extended portion 20; These screw receivers correspond to the protrusions 17 of the bottom pad 8 through the parts 20.
and the exterior body 5 and the protruding piece 17 of the bottom pad 8, and the screw holder is in the part 2.
0 is connected from the outside with screws 18.

19 is a screw that fixes the other end of the handle 2 to the exterior body 5.

In this embodiment, a seam portion 6 which is a thick portion of the exterior body 5 is used.
The projecting piece 17 of the bottom flap 8 and the screw receiver part 20 of the handle 2 are stacked together in a sandwich-like manner from both the inside and outside sides and are connected with the screws 18, so that the bottom flap 8 and the exterior body 5 of the handle 2 It has the strongest advantage in terms of strength as a bonding structure.

However, the present invention is not limited to the structure in which screws are secured to the joint portion 6. In the embodiment, the screw receiver portion 20 is extended from only one end of the handle 2, but the screw receiver portion 20 is similarly formed at the other end. It can also be secured with screws.

This invention consists of the above-mentioned structure, and the screw receiver formed extending from the end of the handle corresponds to the protruding piece of the bottom flap through the outer body, and these screw receivers are connected to the outer body. and the protruding piece, but since the screw receiver formed extending from the end of the handle comes into contact with the exterior body, the contact area with the exterior body increases, so It can withstand external impact from any direction, and prevents the handle from rattling even after long-term use.

In addition, the screw receiver part, the exterior body, and the protruding piece of the bottom flap are as follows:
Since the screw receiver is screwed from the front, the screwing work is easy and work efficiency is improved.

Furthermore, the screws can be used not only to fix the handle but also to fix the bottom flap.
