[Problems to be solved by the invention] Jitsuko Sho 62-3141
In the gap retainer described in Japanese Patent Laid-Open Publication No. 7-gazette, when it is inserted into the side wall of the tray and covered with a film (lapping), the pressing force from the upper portion causes a downward movement, which makes it difficult to perform accurate packing. Further, in the space holder disclosed in Japanese Utility Model Publication No. 1-23984, when inserted into the tray side wall, the holding portion for fixing the outer edge portion of the tray side wall upper portion is a single member, which is a single member. It has both a spring mechanism and a tray fixing function. For this reason, when the film is covered (lapped) from the upper portion of the film supporting portion, there is a problem that the pressing force from the upper portion causes a downward movement, which prevents accurate packing. Further, since the sandwiching portion located on the outer edge portion of the tray side wall is a single member, it is unstable due to a rattling movement to the left and right during lapping.
From this point too, I could not make an accurate pack. Further, in the conventional space holder, since the film support portion is a plate-like body,
Although this plate-shaped food is transparent plastic, it is difficult to see, and this plate-shaped body may be clouded by water vapor.
In this case, there is a problem that the food becomes more difficult to see. In addition, conventional spacing devices require a coated film

there were. The present invention has been made in view of the above points,
By forming the bifurcated portion (engaging portion) in the side view with at least five leg structure, vertical and horizontal movement (sway) is prevented and stabilized, and lapping can be performed accurately and easily. It is another object of the present invention to provide a gap holder for a food packaging pack, which can prevent damage to the film more reliably and make the food inside the tray easy to see.

[0004]

In order to achieve the above-mentioned object, a gap holder for a food packaging pack according to the present invention covers an upper opening of a tray containing food, as described with reference to the drawings. Supporting the lower surface of the transparent film to form a space for storing food between the transparent film and the tray,
In an elastically deformable gap holder for a food packaging pack made of synthetic resin, at least a five-legged engaging and sandwiching portion 1 which engages a side wall 18 of a tray 16 to sandwich the side wall of the tray.
2 and a film support portion 14 that is connected to the engaging and pinching portion 12, and the engaging and pinching portion 12 includes two left and right inner fixing legs 20 and 20 that contact the inner surface of the tray side wall 18, and a tray side wall. Left and right outer fixed legs 2 contacting the upper peripheral edge of the
4 and 24 and one central spring leg 26 provided between these outer fixed legs,
Has two arc-shaped rod-shaped members 30 and 30, and a plate-shaped member 32 integrally provided between the tips of these rod-shaped members. The inner wall of the outer fixed leg has a tray side wall. 18
At least one small projection 34 for fixing the upper is provided at the lower end of the front Symbol central spring legs 26, a generally hemispherical projection 44 to prevent damage to the transparent film is provided in
It is characterized by that.

[0005]

As shown in FIG. 11, the space holder 10 is inserted into the side wall 18 of the tray 16 containing the food 40 with one touch. Specifically, two left and right inner fixed legs 20, 20
Contacts the inner surface of the tray side wall 18 and one central spring leg 2
6 is inserted so that the outer surface of the tray side wall 18 is pressed from the outside. Thus, when inserted, the two left and right outer fixing legs 24, 24 are fixed by grasping the upper outer surface of the tray side wall 18. Since the small protrusion 34 is provided on the inner surface of the outer fixed leg 24, it is more stable when the small protrusion 34 is inserted into the upper peripheral edge portion 22 of the tray side wall 18, and when it is not inserted,
The tray side wall 18 also serves as a slip stopper against the upper peripheral edge portion 22 and can be more stably fixed. In this way, the spacing member 10 is stably fixed to the tray side wall 18. When the transparent film 42 is covered from above, the inner surface of the film 42 is lifted and a large space is formed inside the tray 16. For this reason, even if the food comes out above the height of the side wall of the tray at the time of serving, the film does not come into contact with the food. Further, since the film supporting portion 14 is composed of the two rod-shaped members 30 and 30 and the plate-shaped member 32 integrally provided between the tips of these rod-shaped members, the food in the tray is moved upward or downward. You can easily see it from diagonally above. Then, the tray 16
The covered transparent film 42 is folded back to the center spring leg 26.
Although it contacts the piece 28, the end of the folded piece 28 is substantially a hemisphere.
