Description

[Detailed description of the invention] The present invention is a thermos container such as a thermos flask or a kettle using a so-called liquid pumping method, in which the liquid inside the main body is drawn out to the outside by a liquid pumping device such as an air pressure pump or an axial flow pump. It is related to.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A heat-retaining container according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

In the following description, a liquid pumping type thermos flask is used as an example.

In FIG. 1, reference numeral 1 denotes the main body of the legal bottle, 2 an inner container for liquid storage consisting of a vacuum double bottle disposed inside the main body 1, and 3
4 is a lower opening member made of synthetic resin that constitutes the upper part of the main body 1; 5 is a lower opening member 4;
7 is an air pump as a liquid pumping device disposed inside the lid 5, and 8 is tightly fitted into the liquid supply port 9 of the inner container 2. 1o is a pipe for pumping up the liquid content, and 11 is a spout pipe for discharging the liquid content to the outside.

In this thermos flask, the air pump 7 in the lid body 5 is connected to the inner container 2.
The liquid in the inner container 2 can be led out to the outside through the pumping pipe 10 and the spouting pipe 11 by the pressurized air that is forced into the inner container 2 .

In addition, in this thermos flask, the lid 5 is held in the closed state by engagement between the lock lever 12 pivotably supported on the side opposite to the hinge pin of the lid 5 and the claw piece 13 on the lower mouth member 4 side. We are trying to maintain this.

Further, on the opposite side of the hinge pin 6, there is a beak portion 14 that exposes the spouting tube 11, a gutter-like portion 4a made of a part of the lower mouth member 4, and a reverse gutter-like portion made of a part of the lid body 5. By 5a,
It is formed.

That is, when the lid is closed, the beak portion 14 is formed by matching the lower mouth member gutter-like portion 4a and the lid reverse gutter-like portion 5a.

The distal end opening 11a of the spouting tube 11 projects downward from the hole 15 at the bottom of the beak 14.

This beak part 14 has a spouting auxiliary pipe 1 which has a passage connected to the passage in the spouting pipe 11 and has a spout 17 below.
A specific example of the mounting structure will be described in detail with reference to FIGS. 2 to 5.

In the case of FIG. 2, the lower mouth member gutter-like part 4a and the lid body reverse gutter-like part 5a
Projections 18 and 19 are integrally provided on the mouth edges of each of the pipes, while a window hole 20 into which the beak part 14 is to be inserted is formed by cutting out one side of the square tube part at the top of the spouting auxiliary pipe 16. Moreover, a groove 22 sandwiched between a pair of protrusions 21, 21 is formed at the upper end of the remaining three inner surfaces of the rectangular tube part.

By sandwiching the protrusions 18 and 19, which are fitted into the grooves 22, between the hinge pins 21 and 21, the lower mouth member 4 and the lid body 5 can be freely engaged and detached. combined.

In the case of FIG. 3, the hole 15 at the bottom of the beak 14 is formed of a threaded cylinder 23, and the threaded cylinder 23 is formed as a part of the lower mouth member gutter-like part 4a and a part of the lid body gutter-like part 5a. is forming.

On the other hand, a threaded portion is formed at the upper end of the auxiliary pouring pipe 16.

By screwing the pouring auxiliary pipe 16 into the threaded cylinder 23, the lower mouth member 4 and the lid body 5 are removably connected.

In the case of FIG. 4, both sides of the lower mouth member gutter-like part 4a, both sides of the lid reverse gutter-like part 5a, a pair of recesses 24 and 24, and the curved piece 2, respectively.
5, 25, and a lower shaft protrusion 26.26 that fits into the recess 24.24 on the circumferential inner surface of the rectangular tube part of the upper part of the spouting auxiliary pipe 16, and an upper shaft projection 26.26 that engages with the curved pieces 25, 25. The protrusions 27, 27 are formed.

The auxiliary pouring pipe 16 is able to rotate in an arc in the direction of arrow A or B around the shaft protrusion 26. are engaged to releasably connect the lower mouth member 4 and the lid body 5.

Note that the formation positions of the recess 24, the curved piece 25, and the shaft protrusion 26 and the protrusion 27 may be reversed. In that case, when the auxiliary spout pipe 16 is rotated in the direction of arrow B in the opposite direction to the above, the lower opening The member 4 and the lid body 5 are detachably connected.

In the case of FIG. 5, two pairs of vertical grooves 2B are provided on both sides of the beak 14 from the upper end of the lid body inverted gutter-like part 5a to the lower mouth member gutter-like part 4a;
28.28.28 and horizontal grooves 29 that are continuous with the respective vertical grooves 28 are formed respectively, while projections 30, 30 that engage with the vertical grooves 28 and the horizontal grooves 29 on both sides of the inner surface of the spouting auxiliary pipe 16 are formed.
The formation is on.

Then, after covering the spout auxiliary pipe 16 from above the beak part 14 and engaging the protrusions 30, 30, etc. along the vertical grooves 2B, 28, etc., horizontally along the horizontal grooves 29, 29, etc. By moving the lower opening member 4 and the lid body 5, the lower opening member 4 and the lid body 5 are releasably connected.

In the above description, a thermos flask is used, but the present invention can also be applied to a heat-retaining container such as a water kettle.

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

That is, according to the present invention, (1) The auxiliary pouring pipe 1 is attached to the beak portion 14 which is composed of a part of the lower mouth member 4 and a part of the lid body 5 that can be opened and closed with respect to the lower mouth member 4.
6 is provided so that the lower mouth member 4 and the lid 5 can be detachably connected to each other by the auxiliary spout pipe 16, so that when the main body falls over, the lid locking mechanism is inadvertently disengaged and the lid 5 is opened. You can prevent accidents such as leaking of contents such as boiling water by closing the lid (2)
) Since the pouring auxiliary pipe 16 can be made detachable,
There are practical effects such as easy cleaning of the pouring auxiliary pipe 16 and hygiene.
