下につながり好ましくなかつた。 In conventional packaging trays of this kind, the entire tray is wrapped in a stretch film, and on the back side of the tray, the films are overlapped in double or triple layers, and the self-adhesive properties of the film are used to seal the tray. . This would require a film with an area two to three times the opening area of the tray, which is extremely wasteful in today's world where resource conservation is a priority, and the overlapping portions would wrinkle. If the juice seeped out from this area and it got bad, the seal would come apart. Furthermore, since the packaging tray has films stacked on top of each other up to its back side, the work required is excessive, which is undesirable and leads to a decrease in efficiency.
本考案は従来の包装用トレーの上記の欠点に鑑

する接着剤２を塗布しておくものであつて、これ
により、強固な包装形態が得られるものである。 These trays 1 are made of a variety of materials, ranging from those that exhibit some degree of adhesiveness to the stretch film (soft vinyl chloride) (PVC trays) to those that exhibit almost no adhesiveness (PE trays). Therefore, in the present invention, an adhesive 2 having good adhesion to the stretch film is applied to the substantially vertical adhesive application surface 1a or 1a' on the entire upper outer circumference of the peripheral wall 1c of the tray 1. In addition, this provides a strong packaging form.
上記接着剤２は、トレー１の開口部周縁の上面
に塗布するのではなく、第１図及び第２図に示し
た様に周壁１ｃの上部外側面全周に形成された略
垂直な接着剤塗布面１ａ，１a′に塗布しておくも
ので、これにより満足のいく結果が得られる。 The adhesive 2 is not applied to the upper surface of the periphery of the opening of the tray 1, but is applied to a substantially perpendicular adhesive layer formed all around the upper outer surface of the peripheral wall 1c as shown in FIGS. 1 and 2. The coating is applied to the coating surfaces 1a and 1a', and a satisfactory result can be obtained.

にフイルム１８を離すものである。 Next, to show an example of the packaging method, after applying the adhesive 2 to the application surface 1a as described above, the tray body 1 is cut on the mounting table 7 as shown in FIGS. 4 to 6. Fit it into frame 8. The cutting frame 8 is made of an electrically insulating material such as asbestos, and a resistance wire 9 such as a nichrome wire is stretched on the outer circumferential surface of the cutting frame 8.
0 are provided at appropriate intervals. Further, the mounting table 7 is provided with a large number of intake holes 11, and an intake chamber 13 is formed by a covering box 12 attached to the lower surface.
An intake pipe 14 connected to a vacuum pump is connected to this intake chamber 13 via a switching valve. Furthermore, a heating plate 15 formed in the shape of a hollow thin box made of metal with good thermal conductivity is provided above the cutting frame 8 into which the tray body 1 is fitted. Inside the plate 15, an appropriate number of heaters 16 are arranged at equal intervals. Also, this heating plate 1
A large number of small holes 17 are formed on the lower surface side of 5, and a film 18 is formed on the lower surface 15a which becomes the heating surface.
The heating plate 15 is coated with Teflon resin to prevent seizure, and an intake pipe 19 is connected to the top of the heating plate 15, which is connected to a vacuum pump (not shown) via a switching valve. The switching valve is connected to a vacuum pump and acts on the heating plate 15 through the intake pipe 19 only when heating the film 18, and sucks the film 18 from each small hole 17. The film 18 is removed from the lower surface 15 of the heating plate 15 by suctioning and removing the air between it and the heating plate 15.
(a) That is, the film 18 is brought into close contact with the heating surface over the entire surface, and the film 18 is heated to its softening point in a short period of time. When heating is completed, the valve is opened to the atmosphere or the film 18 is actively released using exhaust gas.

シール性が得られる。 Next, the film holding frames 20 and 21 are lowered to overlap the heated and softened film 18 on the tray body 1, and then air is generated in the supply chamber 19 to spread the film 18 around the tray 1 and around the cutting frame 8. Closely contact. In this case, due to the presence of the frame 22 around the seventh mounting plate, the film 18 is shielded from the outside air as shown in FIG. Make a close contact as shown in the figure. At this time, since the adhesive 2 is applied to the adhesive surface 1a of the packaging tray 1 according to the present invention, the adhesion of the film 15 to the adhesive surface 1a of the tray body 1 becomes even more perfect, and the cutting frame The intake hole 10 of No. 3 ensures that the film 18 is in close contact with the resistance wire 9 on the outer peripheral surface of the cutting frame 8. Furthermore, since the film 18 is softened, it exhibits self-adhesive properties and adheres tightly to the adhesion surface 1a of the tray body 1 due to the suction action, thereby providing perfect sealing without any wrinkles.
そして最後に、切断枠８の周囲の抵抗線９に通
