Description

[Detailed explanation of the invention] (a) Industrial application field This invention relates to food trays used when arranging and selling foods such as sashimi, and prevents the transparent film (lap film) that covers the food from adhering to the food. A tongue-like piece that helps lift the film can protrude from the top of the tray.

(b) Conventional technology Food to be served on trays is usually wrapped and packaged with wrap film, but especially when food is eaten as is, such as sashimi, the film sticks to the food, creating an unsanitary feeling, so the film is left floating from the food. need to be packaged. For this reason, conventionally, a support piece made of plastic molding or the like was separately attached to the upper edge of the tray, and the film was packaged so as to float above the upper edge of the tray.

(c) Problems to be solved by the invention However, since the support pieces in the conventional method were attached separately, they easily came off, and there were also difficulties in workability during packaging.
The present invention attempts to solve this problem by providing a tongue-shaped piece serving as a support piece on the tray itself. Regarding the method of providing a tongue-like piece on the tray itself and using it as a support piece, see
Utility model registration application filed in 1988 by the same person as the present application
Although the application has been filed as No. 102257, the present proposal provides a method that differs in embodiment from the earlier application.

(d) Means for Solving the Problems To explain with an embodiment, Fig. 1 is a three-dimensional view of a food tray in an inventory state according to embodiment A, in which a tray 1 made of plastic molding extends diagonally downward from the upper edge 2. A molded tongue-like piece 3 is provided, and the tongue-like piece 3 has an inclined surface 3.
It consists of a, a folding line 3b, a strut 3c, a rib 3d, a lap plane folding line 3e, and a lap plane 3f. FIG. 2 shows a three-dimensional view when in use, in which the tongue 3 is folded upward from the folding line 3b and the side edge 3g of the support column 3c is moved to the upper edge of the tray.
When engaged with the locking recess 4 provided in the tray, the upper side and lap surface 3f of the support column 3c protrude from the upper edge 2 of the tray and are supported.

(e) Effect FIG. 3 is a plan view showing only the molded portion of the tongue 3 of Example A, and a cross section taken along the line A-A' is shown in FIG. 4. When bent from the curve 3b and locked at the position shown by the dotted line in FIG. 4, food 8 such as sashimi is placed in the tray 1 and covered with the wrap film, the wrap film 5 is held by the support 3c as shown in the explanatory cross-sectional view of FIG. Since it is set up like a tent, it does not come into contact with the food 8. When the wrap film 5 is used to cover the whole body, a force is applied to the tongue-like piece 3 inwardly, but the tongue-like piece 3 does not simply protrude, but has a structure in which it supports the support column 3c on an inclined surface 3a, and also The provided ribs 3d increase resistance to bending. Further, the wrap surface 3f, which is the tip of the tongue-shaped piece 3, is bent from the wrap surface folding curve 3e when the wrap film is hung, and serves to receive the wrap film 5 with the surface and prevent the film from being damaged.

(F) Embodiment Embodiment B in which the upright locking of the support column 3c is achieved by a locking recess 4 provided on the upper side of the tray is shown in a three-dimensional view in FIG. A locking recess 4 is formed in the vertical direction on the upper side of the tray using an outline cutting die, and the side edge 3g of the support column 3c is engaged with the locking recess 4. FIG. 7 is a plan view of the tongue-shaped portion of Example B, and FIG. 8 is a cross-sectional view taken along line B-B' of the example. When the recess 4 is formed, only the upper part of the side surface is removed, so that the function of the tray is not impaired.

FIG. 9 is a three-dimensional view of Embodiment C, and as also shown in the plan view in FIG. 10 and the sectional view taken along the line CC' in FIG. By a method that facilitates the molding process, a diagonal surface folding line 6 is provided at the connection position with the upper edge 2 of the tongue-shaped piece 3,
When in use, it is bent downward to form a usage pattern similar to that of the two-row embodiment.

FIG. 12 is a three-dimensional view of Example D at the time of inventory, and FIG.
The figure is a three-dimensional view when in use, FIG. 14 is a plan view of extraction of the tongue portion, and FIG. 15 is a sectional view taken along the line D-D'. From this, an engaging piece 7 is derived parallel to the oblique surface 3a with a gap slightly larger than the thickness of the tongue-like piece 3, and the gap created by the two left and right engaging pieces 7 has a dimension slightly smaller than the width of the support column 3c. As a result, the support 3c can be press-fitted from the gap, and the support 3c can be locked more stably.

(g) Effects of the invention As explained above, the tray itself has a tongue-shaped piece that can floatingly wrap the wrap film, so it is reliable without the disadvantage of the conventional separately attached support piece coming off, and it is easier to work than attaching a separate piece. But it becomes even more advantageous. Furthermore, since the work of folding back the tongue and locking it onto the upper edge of the tray can be done with one touch, it can be easily and reliably carried out whether the film wrapping process is mechanized or done manually.
