Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a take-out food container such as a pork cutlet or croquettes, which is laid for take-out food such as fried food at the bottom of the container for draining or oil draining, or to prevent stickiness on the wall surface of the container. Regarding packaging materials.

[0002]

2. Description of the Related Art In containers such as take-out foods that contain foods that are likely to produce moisture or oil, the moisture or oil from the foods causes the bottom of the container to become sticky, and when the foods directly touch the sticky portion, the moisture The taste of the food is impaired due to the scent and deterioration caused by the return of oil and oil. Also,
When food comes into direct contact with the wall surface of the container, the contact portion becomes sticky. Therefore, in the case of adding such foods that easily release water and oil, a sheet with water absorption or oil absorption, or a guest tray with small holes or irregularities is laid on the bottom of the container, or the contents are wrapped in a sheet. Dribbling is common practice. Further, as described in Japanese Utility Model Laid-Open No. 63-1761, the container itself has a double bottom and a small hole for draining is provided in the upper bottom, and the one described in Japanese Utility Model Laid-Open No. 3-45874. In some cases, a non-woven sheet is stretched by forming a flange around the bottom of the container.

[0003]

A conventional sheet laid on the bottom of a container or wrapping contents, or a guest tray laid for draining or oil draining, absorbs water or oil by itself. Alternatively, water or oil is drained by using small holes or irregularities, but the amount of water or oil that can be absorbed is small due to the limited thickness of ordinary sheets, and the contact area with the contents is large. Therefore, there is a problem that stickiness or fluff occurs due to the return of water or oil, and the ventilation is not good, and the same problem occurs due to the large contact area of the one provided with small holes. Further, a sheet having unevenness on the surface of the sheet is effective as a means for preventing the contents from adhering to each other, but the ventilation is not so good, and the water and oil accumulated in the recess are absorbed again. Also occurs. Further, making the container a double bottom or fixing the non-woven fabric sheet to the flange so as to cover the bottom has a complicated structure and is not suitable in terms of cost for takeout foods.

The present invention has been made to solve the above problems, and by disposing it on the inner surface of a takeout food container, the contact area with the contents is reduced,
Moreover, it is an object of the present invention to obtain a packaging material that can eliminate the fluffiness and stickiness caused by the return of water and oil from the contents, and ensure ventilation and prevent the deterioration of the contents.

[0005]

The packaging material for takeaway foods according to the present invention is a molding packaging material arranged on the inner surface of a container for takeout foods, wherein a plastic net is provided on both sides of the net surface before molding. It is characterized in that it is formed so that convex portions are alternately formed on each of the above so as to form an uneven shape as a whole.

[0006]

The take-out food packaging material of the present invention is formed by forming the plastic net into convex and concave parts on both sides with the net surface before molding as a reference, so that the net becomes uneven. If you place the food on the bottom of the take-out food container and place the food on it, only the convex portion on the top side will contact the content, so the contact area will be smaller, and the contents of the food will come out through the eyes of the net. Since water and oil flow down, the water and oil are blocked from the contents, so that the contents are prevented from becoming damp or sticky. Also, under the contents, air freely flows through the eyes of the net, thereby preventing the contents from getting wet. Further, when the packaging material is arranged on the wall surface of the container, the contents do not come into direct contact with the wall surface of the container, ventilation is sufficient, and stickiness on the wall surface is prevented.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a partial perspective view of a packaging material according to an embodiment of the present invention, FIG. 2 is a partial plan view of the packaging material, and FIG. 3 is a sectional view showing a part of the packaging material in an enlarged manner. FIG. 4 is a perspective view of a takeout food carton using the packaging material as a guest tray.

In this embodiment, the packaging material 1 uses a net made of PP (polypropylene), PE (polyethylene) or the like, and the net is shaped like a truncated cone alternately in the vertical and horizontal directions based on the net surface before molding. The protrusions 2 _U and 2 _L are shaped so as to form, and the protrusions and recesses are formed as a whole as shown in the figure. The upper surface of the packaging material 1, the convex portion 2 of the lower surface which is located between the convex portions 2 _U and the convex portion 2 _U aspect each direction _L
On the contrary, the lower surface side has a concave shape at the upper surface side convex portion 2 _U located between the convex portion 2 _L and the convex portion 2 _{L in} the vertical and horizontal directions. . Further, as shown in FIG. 3, a space 3 _U is formed in which the convex portions 2 _U are completely communicated with each other on the upper side of the reference surface (dotted line portion), and also between the convex portions 2 _L is completely on the lower side of the reference surface. It is a communication space 3 _L. A space 3 _U, 3 _L of the upper and lower communicates through the eyes of the net.

The packaging material 1 is cut into a predetermined shape and laid on the bottom of a carton 4 for take-out food as shown in FIG. 4 or arranged inside the wall surface of the carton 4. And the contents, Tonkatsu, Shumai, Anman,
Food for take-out, such as nigaku-man, croquette, tempura, manju, and fried chicken, can be placed. If the contents are oily, the carton 4 is preferably made of oil-resistant paper or a polyethylene-laminated plate material so that the oil does not soak into it. It may be formed of ordinary cardboard. Further, the shape is such that the four corners are pasted in order to prevent the oil and the like from flowing out from the bottom surface, but when the oil content is small, it may be an auto bottom.

When food is placed on the packaging material 1 laid on the bottom of the carton 4 as described above, the convex portion 2 on the upper surface side of the packaging material 1 is placed.
Only _U will come into contact with the contents, and water and oil that have come out of the contents will fall downward and collect at the bottom of the container. Further, under the contents, the air freely flows through the eyes of the net, which prevents the contents from getting wet due to steam or oil mist. Further, when the packaging material 1 is disposed inside the wall surface of the carton 4, the contents are prevented from directly contacting the wall surface of the container,
Ventilation is secured and stickiness on the wall surface is prevented.
