Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a heat-insulating container for a rotating dining table using a crescent chain, for serving products while keeping them warm.

BACKGROUND OF THE INVENTION A large number of restaurants have appeared in which a crescent chain is run sequentially over a counter to form a rotating eating and drinking table, where customers can select and eat from various products conveyed on the crescent chain. There is.

Conventionally, this type of restaurant has been unable to keep the products on the Crescent Chain warm, so the products they offer are limited to foods that do not need to be kept warm, such as sushi (sushi). there were. Therefore, the applicant previously proposed a heat retaining device for a rotary dining table that can effectively deal with this problem (Patent Applications (1) and (2) dated March 9, 1988).

This product uses heat-retaining steam from a steam generator installed on the bottom of the Crescent Chain to flow into the vicinity of the product surface on the pedestal through a steam pipe that opens onto the pedestal placed on the top of the Crescent Chain. The upper end of the steam pipe is equipped with an on-off valve, so when the product is placed on the tray, this on-off valve opens and steam spews out, causing the product on the tray to flow out. It is possible to effectively keep the product warm.

Problems to be Solved by the Invention In terms of products, this prior art merely presents a general container with holes for vapor transmission in the bottom and a mesh tray in the middle. Therefore, this product is dedicated for this purpose, and there is a problem in that its manufacturing cost tends to be high.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a rotary drinking and drinking device that can reuse a container known as a dim sum container as a container body, and that can effectively keep products warm with steam on a crescent chain. The purpose of the present invention is to provide a heat insulating container for a table.

The structure of the present invention to achieve this object consists of a container main body having a vapor permeation hole formed in the bottom plate, and a valve operating body protruding from the lower surface of the bottom plate, which runs sequentially on two sides of the counter. The gist is that when the container body is placed on the pedestal fixed to the crescent chain, the valve operating body opens the on-off valve of the steam pipe that opens onto the pedestal.

Note that the valve operating body can be changed into various forms, and the container body may be provided with a lid that is permeable to steam.

With this configuration, when the container body containing the product is placed on the cradle, the valve operating body opens the on-off valve.
Steam from the steam pipe can rise up into the interior of the container body through the steam permeation holes in the bottom plate, thus effectively keeping the product warm.

Moreover, since the on-off valve closes when the container body is removed from the cradle, there is no risk of unnecessary steam spewing out from the steam pipe.

It works as described above.

Example Examples will be described below with reference to the drawings.

Heat-insulating container for rotating eating and drinking table (hereinafter simply referred to as container) 10
consists of a container body 11 and a lid 12 (Fig. 1),
A valve operating body 13 is provided protruding from the lower surface of the former bottom plate 11b.

The container body 11 includes a bottom plate 11b provided at the inner lower part of a cylindrical outer tube 11a, and a lid 1 on the upper edge of the outer tube 11a.
A thin wall portion 11C is formed for fitting 2 (FIGS. 1 and 2). The bottom plate 11b is formed by laying a large number of narrow plate materials in parallel, and by providing a trapezoidal recess at the side end of each plate material, a plurality of vapor permeation hole lids,
The lid... is formed.

The valve operating body 13 is fixed to the center of the bottom plate 11b, and has a round bar-shaped protrusion 13b in the center of the disc-shaped base 13a.
It forms. Here, the height of the protrusion 13b is equal to the height of the outer cylinder 1.
It shall be determined to have an appropriate size that does not protrude below 1a.

The lid 12 consists of an outer cylinder 12a that fits from the outside into the upper edge of the outer cylinder 11a of the container body 11, and a dome-shaped lid part 12b that is formed on the inner upper part of the outer cylinder 12a and curves upward. Figure 1). The lid portion 12b is made of, for example, a bamboo material formed into a ribbon shape and woven in an Ajiro pattern, and steam can freely pass through the mesh.

The rotating eating and drinking table is made up of a crescent chain 20 that runs sequentially on the upper surface of the counter C (FIGS. 3 and 4). Here, the crescent chain 20 connects links 22, 22, . If a product plate is placed on the top surface of this talent, the product plate can be conveyed sequentially along the counter C.

The crescent chain 20 has cradle 2 at appropriate intervals.
3.23... is fixed, while the link bin 22
The sprocket 24 meshes with the large diameter roller 22b that is loosely fitted into the roller 22b, and the sprocket 24 is connected to the motor 24b via the drive chain 24a.
The crescent chain 20 can be driven to travel.

The pedestal 23 includes an upper plate 23a on which the container body 11 can be positioned and placed, and a lower plate 23b for fixing the pedestal 23 to the crescent, and the intermediate part thereof is filled with a heat insulating material 23c. It is. A steam pipe 26 from the steam generator 25 opens in the center of the upper plate 23a. However, even if the pedestal 23 moves due to the running of the crescent chain 20, the steam pipe can be moved via a connection mechanism (not shown) or by making the steam generator 25 movable together with the crescent chain 20. 26 shall always be in communication with the steam generator 25.

An on-off valve 27 is attached to the upper end of the steam pipe 26 (FIGS. 4 and 2). The on-off valve 27 includes a valve body 27a and a compression spring 27b that pushes up the valve body 27a from below to close the steam pipe 26. The on-off valve 27 can be opened by pushing down the valve body 27a.

Now, when the container main body 11 is not placed on the upper plate 23a of the pedestal 23, the valve body 27a of the on-off valve 27 is pressed against the compression spring 27.
Since it is pushed upward by b, the on-off valve 27
is in a closed state (Figure 2). At this time, the valve body 27a
The upper part of the upper plate 23a is assumed to be highly protruding from the upper surface of the upper plate 23a (as indicated by the two-dot chain line in FIG. 5).

Next, when the container body 11 is placed on the pedestal 23, the protrusion 13a of the valve operating body 13 pushes down the valve body 27a (solid line in the figure). The on-off valve 27 is in the open state. Here, since the valve operating body 13 is protruded from the center of the bottom plate 11b of the container body 11, when the container body 11 is properly positioned on the pedestal 23, the valve operating body 13 and the valve The bodies 27a always come to face each other.

Further, at this time, it is assumed that the protrusion 13a of the valve operating body 13 is set at an appropriate height so that the valve body 27a can be pushed down sufficiently.

In this way, when the on-off valve 27 is opened, the steam from the steam generator 25 is spouted upward through the on-off valve 27, and the steam permeation hole li formed in the bottom plate 11b of the container body 11 is
It can rise upwards via d, lid, and so on. Therefore, the product SSS... placed on the top surface of the bottom plate 11b and stored in the container body 11 can be well kept warm. It goes without saying that the container body 11 placed on the pedestal 23 may be the container 10 covered with the lid 12.

In the above description, the container 10 has the same form as a so-called dim sum container including the lid 12 when the valve operating body 13 is not provided.

The valve operating body 13 has column bodies 13g, 113g, etc. on the upper plate 13h.
. . , and a lower ring 13f is provided as a support body 13d, and the entire inside of the ring 13f can be made into a plate body 13c made of a perforated plate (FIG. 7). The opening operation of the on-off valve 27 can be made more reliable. In this case, the perforated plate may be a strong net.

A bottomed cylindrical shape is made of a perforated plate, and an upper plate 13 is attached to this.
h may be attached to form the valve operating body 13 (eighth
figure). The bottom part forms the plate body 13c, and the cylindrical part forms the support body 13.
d. Note that in each of the embodiments shown in FIGS. 7 and 8, the upper plate 13h may be omitted.

Furthermore, the form of the valve body 27a can be arbitrarily deformed in order to ensure the depressing operation by the valve operating body 13 or to increase the opening area when the on-off valve 27 is opened. For example, a top plate 27c having through holes 27d, 27d, etc. may be formed on the upper end surface of the valve body 27a (Fig. 9), or large openings 27f, 2
7f..., and the columns 27e, 27e.
