Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an improvement of a pot in which a draining member is attached to the mouth of a metal vacuum double container.

<Conventional technology> Conventionally, a pot has a vacuum double-walled container with vacuum insulation between the metal inner and outer walls, and a male thread is carved on the outer periphery of the mouth of the container, which communicates with the mouth of the container in the center. A drainage member with an opening is provided, a cylindrical hanging rib is provided hanging downward from the outer peripheral end of the peripheral wall forming the opening, and a female thread is carved on the inner periphery of the hanging rib,
Screw the female screw of the draining member into the male screw of the container, attach the opening of the container and the draining member, and attach the bottom member to the bottom of the container. However, in this type of pot, the container and draining member are simply screwed together, so they are not securely fixed, and it is difficult to attach and remove the stopper, which is attached toward the center opening of the draining member. As a result, the threaded draining member loosened from the mouth of the container, resulting in poor safety.

<Purpose of the invention> The present invention has been made in view of the above points, and the object is to provide a pot with a simple structure and a draining member securely and easily attached to the container.

<Structure of the invention> According to the invention, an annular projection is provided on the outer peripheral wall of the opening of the container, a handle is integrally molded on the rear end of the upper part of the draining member, and an annular projection of the container is provided on the outer peripheral inner wall of the lower part of the draining member. A fastening tool that provides an annular groove into which a protrusion is forcefully fitted, cuts out the rear end of this annular groove and the lower rear end of a draining member, and forms a vertically divided groove, and fastens the draining member to the outer wall of a container. The objective is to be achieved by simply tightening the vertical grooves with this fastener and fastening the drainage member to the outer wall of the container.

<Example of idea> Embodiments of the present invention will be described below with reference to the drawings.

The pot 1 includes a double-walled metal vacuum container 2, a draining member 4 that is attached to the mouth of the container and has a handle 3 integrally molded at the rear end, a fastener 5 for tightening the draining member to the mouth of the container, and a stopper 6. It is composed of.

The container 2 consists of an inner wall and an outer wall made of metal such as stainless steel, and the inner wall has a cylindrical inner wall body with a bottom and a diameter smaller than the inner diameter of the inner wall body by curving inward from the upper end of the inner wall body. It is integrally molded with the inner wall opening.
An annular projection 7 is provided on the inner periphery of the lower end of the inner wall opening for locking a seal of a plug 6, which will be described later.

The outer wall of the container is formed by integrally molding a bottomed cylindrical outer wall shell separated from the inner wall shell by a predetermined distance, and an outer wall opening that curves inward from the upper end of the outer wall shell and has a diameter smaller than the inner diameter of the outer wall shell. ing. The upper end of the inner wall mouth of the inner wall of the container and the upper end of the outer wall mouth of the outer wall are welded, and among these,
A vacuum is maintained between the outer walls. On the outer periphery of the mouth of the outer wall of the container, an annular projection 7 for locking a draining member is provided. This annular projection may be externally threaded.

As shown in FIG. 2, the draining member 4 has an opening in the center that communicates with the mouth of the container, and a receiving part 8 that is suspended above the outermost periphery of the peripheral wall forming this central opening, except for the front part. A beak portion 9 that communicates with the central opening at the front and has a liquid flow path, a cylindrical hanging wall portion 10 that hangs downward from the outermost circumference of the lower end of the receiver, and a beak portion 9 that extends outwardly from the upper rear end of the cylindrical hanging wall portion protruding handle 3
and a pair of locking pieces 15, 15 protruding from the lower rear end of the cylindrical hanging wall at the lower side of the upper part of the handle are integrally molded. The central opening of the receiving part 8 of the draining member communicates with the tip of the mouth of the container via the seal packing 12, and a female thread for attaching and removing the plug 6, which will be described later, is carved on the inner periphery of the receiving part above the central opening. There is. The cylindrical hanging wall 10 has an annular groove 13 formed on its inner periphery to fit with the annular protrusion 7 of the container, and as shown in FIG. A vertically divided groove 14 is bored through the gap, and locking pieces 15, 15 are provided on the left and right sides with this vertically divided groove 14 as a boundary. This vertically divided groove 14 cuts out the rear end of the annular groove 13, and also cuts out the rear end of the cylindrical hanging wall portion 10 at the same time. The annular groove of the cylindrical hanging wall may be replaced by a female thread. Each locking piece 15, 15 has an opposing through hole 16, 16 through which a bolt of a fastener, which will be described later, can be inserted.

The fastener 5 is a bolt 17 as shown in FIG.
and a nut 18, and the bolt 17 is inserted through the through hole 16 of one locking piece 15 to the other locking piece 1.
The drainage member is inserted into the through hole 16 of No. 5, and the vertically divided groove 14 is tightened from the outside of the other locking piece with a nut 18 via the locking piece, thereby tightening the draining member around the outer periphery of the mouth of the container.

As shown in FIG. 2, the plug body 6 has a male screw carved into its outer peripheral wall to be screwed into the female screw of the receiving part of the draining member, an inlet at the lower end of the interior, and an outlet communicating with the inlet at the front end. A guide tube is installed vertically from the upper wall of the spout, a valve body is provided for opening and closing the inlet, a push rod is fixed to the lower end and has a seat at the upper end, and the push rod is inserted through the guide tube. A spring that constantly presses upward is interposed between the upper wall of the inlet and the seat, and a lever is provided that can swing around a pivot point. It protrudes from a notch provided in the valve body, and opens and closes the valve body from the inlet in conjunction with the vertical movement of the lever, communicating the liquid flow path between the mouth of the container and the beak.

Reference numeral 19 denotes a bottom member which extends around the outer periphery of the lower end of the container.

<Effects of the invention> In the present invention, the annular groove into which the annular projection is forcefully fitted is cut out at the rear end along with the lower rear end of the drainage member, so when the annular projection and the annular groove are fitted together, the annular groove is cut out at the rear end. Since the notch part acts to release excess pressing force, it can be fitted very easily by just pressing lightly, eliminating complicated work, making the work process efficient, and fitting smoothly, making it easy to fit the container. There will be no damage to the draining member or lumps near the annular protrusion of the container due to pressure with the draining member.

Furthermore, since the structure is the simplest, it is possible to significantly reduce costs due to materials and assembly.

Furthermore, since the vertical grooves are simply tightened with a tightening tool, the annular protrusion of the container and the annular groove of the draining member are tightened and securely fixed, and no force is applied to other parts of the container or the draining member. There is no deformation of these parts.

Furthermore, since the locking piece having the vertical groove and the fastening tool are hidden in the upper part of the handle, it does not look unsightly and does not get in the way when being carried.
