Description

[Detailed Description of the Invention] The present invention relates to a type of heat-retaining container in which liquid is poured by lifting the handle by hand and tilting the main body, that is, a heat-retaining container generally called a handheld pot.

In conventional heat-insulating containers of this type, the handle is merely fixed to the outer surface of the main body with screws, which causes the attachment portion to be relatively weak, resulting in a problem that it cannot withstand long-term use.

The present invention aims to attach the handle easily, reliably, and firmly by integrally forming an annular body at the upper end of the handle and fitting and fixing the annular body to the outer periphery of the lower mouth member of the upper part of the main body. This is the purpose.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Several embodiments of the heat-insulating container of the present invention will be described below with reference to the accompanying drawings.

1 to 6 show a thermos flask according to a first embodiment of the present invention.

The main body 1 of this thermos flask is constructed by integrally combining a synthetic resin-type lower mouth member 2 and an outer case 3 made of thin metal plate, and inside thereof is a vacuum double bottle for storing liquid. An inner container 4 is provided.

The inner container 4 is located inside the main body 1 and is pressed and fixed against the lower mouth member 2 by a support member 6 screwed onto a threaded cylinder 5 fixed to the bottom of the outer case 3.

On the upper surface of the lower mouth member 2, there is a screwed plug insertion hole 7 that communicates with the inside of the inner container 4 and also serves as a liquid supply port, and a screwed plug insertion hole 7 that is connected to one side of the plug insertion hole 7 and serves as a liquid injection port. A gutter-shaped beak portion 8 is formed.

A plug body 9 is screwed into the plug insertion hole 7.

In this embodiment, the plug body 9 is integrally connected to the inner surface of a cap-shaped lid body 10 that covers the upper part of the lower mouth member 2.

A window hole 11 is formed in the lid body 10 and is large enough to expose the beak portion 8 at an appropriate location.By rotating the lid body 10, the beak portion 8 and the window hole 11 are made to be non-overlapping. (See Figure 5)
Alternatively, it can be polymerized (see Figure 6).

Incidentally, at this time, the stopper 9 is opened or opened at the same time.

Further, an annular stepped portion 13 is formed at an intermediate portion of the outer periphery of the side peripheral wall 12 of the lower opening member 2, and a threaded cylinder 14 having a slightly smaller diameter is formed below the stepped portion 13.

An annular member 16 that supports an inward flange 15 formed at the upper end of the outer case 3 is screwed onto the threaded cylinder 14 .

Furthermore, small projections 17 for positioning are integrally provided on the outer periphery of the upper end of the threaded cylinder 14 at appropriate positions.

On the other hand, the handle 18 by which the main body 1 is to be suspended has an inverted shape, and an annular body to be fitted into the threaded cylinder 14 is integrally formed at its upper end.

A recess 20 to be engaged with the small protrusion 17 on the threaded cylinder 14 side is formed at a suitable location on the inner surface of the annular body 19 .

After fitting the annular body 19 to the upper end of the threaded cylinder 14, the annular member 16 is screwed onto the threaded cylinder 14 while supporting the inward flange 15 of the outer case 3, and the stepped part 13 and the annular member 16, the annular body 19 of the handle 18 and the inward flange 15 of the exterior case 3 are clamped and fixed.

At this time, the small protrusion 17 on the threaded cylinder 14 side and the recess 20 on the annular body 19 side fit into each other, and the handle 18 is positioned on the opposite side of the beak 8.

Incidentally, the small protrusion 17 may be formed on the inward flange 15 of the outer case 3 as shown in FIG. 7, and positioning may be performed by engagement with the recess 20 on the annular body 19 side.

8 to 10 show a second embodiment of the present invention.

In this case, an outward flange 21 that supports the inward flange 15 at the upper end of the exterior case 3 is formed at the lower end of the side peripheral wall 12 of the lower mouth member 2 . An appropriate number of protrusions 22 are protruded at positions spaced apart from each other by approximately the same thickness as the annular body 19.

At one end of the protrusion 22 is a stopper 23 that hangs downward.
are integrally formed, and the lower surface of the protrusion 22 is an inclined surface that slopes downward toward the stopper 23 side.

On the other hand, the inner peripheral surface of the annular body 19 of the handle 18 has the protrusion 2
A notch 24 into which the holder 2 is loosely fitted is formed.

After fitting the annular body 19 to the side peripheral wall 12 of the lower mouth member 2 so that the protrusion 22 and the notch 24 are aligned,
The annular body 19 is rotated to engage the stopper 23 of the protrusion 22 at the end of the notch 24, and the annular body 19 is attached to the outer case 2.
The inclined surface 22 a of the lower surface of the protrusion 22 together with the inward flange 15 of
* and the outward facing flange 21.

In this embodiment, the lid 10 is screwed onto the side peripheral wall 12 of the lower mouth member 2 without screwing the plug 9 into the plug insertion hole 7.

Further, in each of the embodiments described above, the annular body 19 of the handle 18 is formed into a donut shape whose inner circumference and outer circumference are concentric circles, but it goes without saying that the outer circumferential shape may be square or the like.

Next, the effects of the heat insulating container of the present invention are listed below.

That is, according to the present invention, (1) the annular body 1 is attached to the upper end of the handle 18 on which the container body 1 is to be suspended;
9 is integrally formed and the annular body 19 is fitted and fixed at an appropriate position on the outer periphery of the lower mouth member 2, so the mounting structure of the handle 18 can be significantly simplified. (2) The handle 18 is attached to the annular body 1
9 will be supported on the main body 1, making the mounting state secure and strong, and improving durability. (3) Since the annular body 19 also serves as the shoulder molding of the main body 1,
It has a decorative effect and other practical effects.
