る。As shown in FIG. 2, the transparent door is a transparent plate made of glass or the like, which has a curved corner (7A) formed in a part thereof, an upper wall (7B), and a front wall (7C) that slopes downward. (7
), and both left and right frames (
9A) (9B) on both left and right sides, handle for opening and closing (10A)
A front frame (10) with a front frame (10) is fitted along the front edge, and on the back side of the transparent plate (7), as shown in FIG. A film (11) is attached. As shown in Figure 4, this film has a base layer (11A) made of a transparent polyester sheet, etc., and is vapor-deposited on the inner side of this base layer, transmitting most of visible light and transmitting most of heat rays (infrared rays). A reflective layer (IIB> mainly composed of silver or titanium oxide, etc. that reflects UV light and blocks most of the ultraviolet rays, and a transparent protective layer (IIC) that protects this reflective layer from moisture inside the refrigerator (6). A glue layer (II) such as transparent acrylic glue formed on the outer surface of the base layer.
D) has a selective transmission/reflection function, which reflects most of the heat rays that try to pass through the transparent plate (7) to the outside of the refrigerator to prevent an increase in the refrigeration load inside the refrigerator (6); Moreover, it is used for the purpose of maintaining the surface temperature of the transparent plate (7) at a temperature higher than the dew point to prevent dew condensation on this surface.
この熱線反射フィルムは、一般には芯材にロール状に巻

コーナー（７Ａ）を有する透明板（７）にこの貼着方法
を用いることは、フィルムに皺が発生して熱線反射機能
が低下するばかりでなく透視効果を損なう致命的な欠点
が生じた。This heat ray reflective film is generally sold as a roll wrapped around a core material, and when pasting it on a flat transparent plate, the roll film is stretched to a predetermined width using an automatic stretching device. An automatic pasting method has been used in which the sheets are cut into pieces and pasted on a transparent plate carried by a conveyor, but this pasting method cannot be used on the transparent plate (7) having the above-mentioned curved corners (7A). However, wrinkles were generated in the film, which not only deteriorated the heat ray reflection function but also caused the fatal drawback of impairing the see-through effect.

間の水を除去し、糊層（１１Ｄ）を透明板（７）に貼着
させる方法を試みた。Therefore, the inventor of the present application sprayed water on the back surface of a transparent plate (7) using a spray method to make the back surface wet, and then applied a heat ray reflective film (
11) on the back side so that the peripheral end surface of the back side is exposed, and press a spatula whose suppressed portion is made of an elastic material such as rubber with some elasticity from the top of the film. Allow the film to move in each direction shown by the arrows in Figure 3, stretch the film, remove the water between the film (11) and the transparent plate (7), and paste the adhesive layer (11D) on the transparent plate (7). I tried a method to get him to wear it.

。In this attachment method, the area of the film (11) is made smaller than the area of the back surface of the transparent plate (7) in consideration of the stretching rate of the film (11), so when the film (11) is stretched, The edges of this film do not protrude outward beyond the edges of the transparent plate (7), making it possible to drain water from flat areas such as the top wall (7B) and front wall (7C), and facing the flat areas. This has the advantage that peeling of the peripheral edge of the film (11) does not occur, and after draining, the exposed part of the back surface and the peripheral edge of the film can be sealed with an oil-based varnish such as Polyurex (trade name). As shown in Figures 3 and 4, the wrinkles caused by the stretching operation with a spatula form peeled parts (12) at both ends of the film (11) facing the corner (7A), At the same time, there is a drawback that air gaps (13), that is, air pockets (bubbles) are formed between the transparent plate (7) and the film (11). Corner (7A
) along with the defect that blisters (14) remain,
As a result, convex surfaces are formed in some places on the fill l (11), so when used as a transparent door (5), not only does the see-through effect of the refrigerator interior (6) deteriorate, but also the heat ray reflection effect This caused the problem that the convex surface expanded and the periphery of the convex surface peeled off from the transparent plate 7), increasing the area of the convex surface.
