It is disclosed in the publication No.

This container uses a blower to circulate air cooled by an electronic cooling element to the storage section. Further, the cover constituting the storage section is kept face down on the device box, and there is no special structure for the seal between this cover and the device box.

This type of device is also disclosed in Japanese Utility Model Publication No. 39-336, but this does not include a blower device.

In general, refrigerators that have a packing attached to the door to seal the door with the main body are, for example,
It is disclosed in the publication No.-4992. According to this, the fixed legs at the base of the packing are fitted and held in the grooves of the outer peripheral frame provided on the periphery of the door.

1 Problems to be Solved by the Invention”
In the invention of No. 36, the sealing at the lower end of the cover is insufficient, and even if the sealing structure of the invention of Utility Model Application No. 58-4992 is applied to these, the connection between the inner and outer plates and the outer peripheral frame is complicated. In addition, the packing requires a cumbersome press-fitting operation to fit the fixed leg into a groove (dovetail groove) with a narrow entrance.

The present invention aims to ensure the sealing between the cover and the base and the base when the cover is constructed of a multi-layer board in the target showcase, and to support the frame attached to the end of the multi-layer board. The problem is to ensure that the packaging is sufficient and that the packing is easily installed and supported.

9. Structure of the Invention ``Means for Solving the Problems'' The showcase of the present invention includes a base having a placement part on the top surface for placing products, and a cooling or heating device that covers the products on the base. The cover has a three-dimensional cover with an opening on the lower side that constitutes a storage room for products to be heated, and the cover has an inner plate and an outer plate arranged in parallel at intervals to form the main body of the cover, and a three-dimensional cover with an opening on the lower side that forms the main body of the cover. a frame member supported along the periphery at lower ends of the inner plate and the outer plate; and a packing supported by the frame member to seal between the cover and the base; has an inner wall and an outer wall facing each other so as to constantly press the surfaces of the inner plate and the outer plate with acting forces in directions approaching each other, and a groove opening downward to connect the inner wall and the outer wall. a connecting intermediate wall, and the packing has a base portion that is held between the narrowing of the opposing wall of the groove with the frame member supported by the inner plate and the outer plate; It is characterized by comprising a soft part that comes into contact with the upper surface of the base.

"Action" The opposing inner and outer walls of the frame have an acting force that forces them to approach each other, and when attached to the inner and outer panels, the inner and outer walls move outward against this acting force. It is done by expanding. For this reason, the frame material is held by pushing the surfaces of the inner and outer panels with restoring force. In addition, the entrance of the groove in the frame material is open before the frame material is attached to the inner and outer panels, making it easy to insert the base of the packing, and when the frame material is attached to the inner and outer panels, the groove becomes narrower so that the base of the packing is clamped, and at the same time, the frame material has a sufficient effect of pressing the inner and outer panels.

On the other hand, the cover (3) partitions the storage room (6), constitutes the surrounding wall and earthen wall of the storage room, and is connected to the base (2) by a hinge device 16) so that it can be opened and closed. It has an approximately hemispherical shape as a whole, and is made up of two transparent inner plates (17
) and an outer plate (18). A packing (19) is provided around the entire circumference of the lower opening of force/<-(3) to maintain airtightness between the opening and the base (2). Inner plate (17) and outer plate (
A sealing material (20) made of desiccant-containing butyl rubber is provided along the entire circumference of the lower end within the space between the inner plate (18) and the inner plate (20).
17) and the frame member (21) supported at the lower end of the outer panel (18).
) is provided. This frame material (21) is made of synthetic resin and has a band-like or annular shape with restoring force, and in the molded state, the opposing inner wall (22) and outer wall (23) approach each other with an opening at the upper end ( 44) is narrow, and when fitting the lower ends of the inner plate (17) and outer plate (18), this width (44) is widened, and in the fitted state,
The inner wall (22) presses against the inner surface of the inner plate (17) on the storage chamber (6) side, and the outer wall (23) presses against the outer surface of the outer plate (18).

The frame material (21) has an intermediate wall (24) that connects the inner wall (22) and the outer wall (23) with the base of the packing (19).
) is formed into a downward groove (26〉) into which the groove (26) is inserted.
Upward grooves (27) and (28) into which the lower ends of the inner plate (17) and the outer plate (18) are inserted are formed between them.

The packing (19) has a hard base (25) and an adjoining hollow soft part (29).

The packing (19) is attached to the base (2) before attaching the frame material (21) to the inner plate (17) and outer plate (18) as shown in Figure 4.
5) is inserted into the groove (26) via adhesive. Between the one-way plate (17) and the outer plate 18), there is a lip (3) extending between the inner plate (17) or the outer plate (18) and both plates (17) (ig).
The sealing material (20) is placed in contact with the lower surface of the sealing material (20) by utilizing its own flexibility and slight adhesiveness. still,
The upward grooves (27, 28) function to maintain a predetermined distance between the two plates (17, 18) by fully inserting the drawing plates (17, 18). Both the inner and outer plates prepared in this way (
17) Fit the inner wall (22) and outer wall (23) of the frame member (21) with the packing (19) attached to the lower end of (18) while expanding them. The intermediate wall (24) with the groove (26) formed by this fitting is located between the inner and outer drawing plates (17) and (18) to receive the lower surface of the sealing material (20), and is positioned between the inner wall (22) and the outer wall. (23) are the inner plates (17
) and the surface of the outer plate (18) are pressed with restoring force. An adhesive is provided between the frame material (21) and the inner wall (22) and outer wall (23) as necessary. (31) is a handle formed integrally with the outer plate (18).

As mentioned above, the frame material (21) has an inner wall (22) and an outer wall (2
3), the lower ends of both the inner and outer plates (17) and (18) are misfitted against the restoring force in the direction of approaching each other. Due to this fitting, the width of the groove (26) is narrowed, so that the base (25〉) of the packing is strongly held between the base (25) and the groove (26).
The packing will also hold better until the adhesive for bonding is cured. As the groove (26) strongly clamps the base (25), the force with which the inner wall (22) and the outer wall (23) press against the inner plate (17) and outer plate (18), respectively, becomes stronger, and the sealing material (20) Improves adhesion. Also, the inner plate (1
7> and the outer plate <18) are made of synthetic resin, so that when distortion occurs due to temperature, it can be absorbed by deformation of the frame material (21).
