Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a coffee pot having a bottomed glass container.

<Prior art> Conventionally, a coffee pot with a glass container with a bottom has a glass container with openings at both ends and a metal container with a bottom, a heat source is attached to the outer circumferential wall of the bottom of the metal container, The upper circumferential edge of the manufactured container and the lower circumferential edge of the glass container are joined together via a sealing pad to form a single container with a bottom, and a coffee funnel is attached to the upper end of this single bottomed container. A lid is removably attached to the top surface, a bottom member with a plug holder at the rear end covers the lower part of the single bottomed container, and the liquid in this container is heated with a heat source. In this coffee pot, the joint between the glass container and the metal container of the single bottomed container could not withstand long-term use due to the difference in heat conduction between the two different materials, and liquid leakage occurred at this joint. Furthermore, since it is a single container with a bottom made up of a combination of a glass container and a metal container, assembly is extremely complicated and costs are high.

<Purpose of the invention> The present invention has been made in view of the above points, and the object is to provide a coffee pot that is highly safe and at a significantly low cost.

<Configuration of the invention> According to the invention, a bottomed container is made of a heat-resistant glass material and has a wide-mouthed upper part, an inclined part extending inward from the lower circumferential end of the upper part, and a cylinder vertically descending from the lower circumferential end of the inclined part. a slanted portion formed integrally with the shaped portion and a bottomed portion that slightly expands outward from the lower circumferential end of the cylindrical portion;
A covered container with good heat conduction that covers the cylindrical part and the bottomed part is attached to the outer wall of the bottomed container, and a heat source is attached to the outer wall of the covered container corresponding to the cylindrical part, and a heat source is attached to the lower circumference of the upper part of the bottomed container. The objective is to be achieved only by a structure in which the upper peripheral edge of the bottom member is tightly joined through a sealing packing.

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

The coffee pot 1 includes a bottomed container 2, a coffee funnel 3 placed on the inside upper part of the bottomed container, a lid 4 that covers the top opening of the bottomed container together with the coffee funnel, and a lower part of the bottomed container. Covering container 5 that covers the outer wall
, a heat source 6 that heats the liquid in the bottomed container, and a bottom member 7 that covers the lower part of the bottomed container, the covering container, and the heat source.

The bottomed container 2 is made of an electrically insulating and heat-resistant glass material, and has an upper wide opening and a spout 8 as shown in FIG. Slanted part 1 extending diagonally inward
0, a cylindrical part 11 vertically descending from the lower circumferential end of the inclined part, and a bottomed part 12 that slightly expands outward from the lower circumferential end of the cylindrical part and has a bottom.

The coffee funnel 3 has a filter paper for coffee powder lined inside and is placed inside the top 9 opening of the bottomed container. This funnel may be removed from the bottomed container after filtering the coffee.

The lid body 4 is made of heat-resistant glass or synthetic resin material and is detachably attached to the opening of the bottomed container upper part 9.

The covering container 5 is made of a thin metal material with good thermal conductivity and slight elasticity, and surrounds the outer walls of the inclined part 10, the cylindrical part 11, and the bottomed part 12 of the bottomed container, as shown in FIG. They are in close contact.

The heat source 6 consists of a band heater attached to the outer wall of the covered container 5 corresponding to the cylindrical part of the bottomed container 2, and heats the liquid in the bottomed container via the covered container 5 and the bottomed container 2. ing.

The bottom member 7 consists of a substantially bowl-shaped bottom body 13 and a bottom plate 14 extending over an opening at the center of the bottom of the bottom body.

The bottom body 13 is open at the center of the bottom, and its upper circumferential edge is in close contact with the lower circumferential edge of the upper part of the bottomed container via the seal packing 15. This seal packing 1
5 is joined to the upper circumference of the bottom body using a heat-resistant and corrosion-resistant elastic material.

The bottom plate 14 is formed into a disk shape, and the bottom body 13
It is screwed to the bottom of the bottom body to close the opening in the center of the bottom of the bottom body.

A handle 16 is screwed to the rear of the bottom body 13, and a plug holder 17 is fixed to the lower rear end of the bottom body 13.

Reference numeral 18 denotes a temperature regulator attached to the angle 19, and the temperature regulator is operated by operating an operating knob 20 to supply power to the heater, which is the heat source 6.

<Effects of the invention> In the present invention, since the single bottomed container is made of heat-resistant glass material, there is no need to connect two containers as in the conventional case and cause liquid to leak from the joint. Moreover, it is highly safe because it has excellent heat resistance.

Further, since the coated container with good heat conduction covers and abuts the lower part of the bottomed container, the liquid in the bottomed container can be quickly and uniformly heated by the heat source installed in the bottomed container. Furthermore, since it can be attached by simply fitting the bottomed container into the covering container and stretching the heat source of the band heater, assembly work is easy and costs can be significantly reduced.
