JPS5852902B2 - Double-sided cardboard tray for packaging - Google Patents

Description

[Detailed description of the invention] Purpose: Traditionally, when packaging utensils, etc. individually or in several cans, yliJ, etc., it is possible to package them without putting them in boxes or the like.
As a means to conserve materials and save costs.

Easy packaging by using cardboard or paperboard as a seat board, placing the item on top of it, covering the whole thing with a synthetic resin sheet, and then heating and shrinking the sheet to tightly seal the item.7
! l: It is being done.

In this case, if paperboard or ordinary double-sided corrugated cardboard (corrugated medium applied to the front and back of an intermediate board is sandwiched between front and back liners) is used as the seat board, the surface of the liner is smooth, so the items placed on top of it may slip. It's easy to package, but it's difficult to do it properly.

In order to prevent the product from sliding, a slightly high wall plate is provided around the seat plate, which has the disadvantage of requiring a large amount of material, time consuming manufacturing, and high packaging costs.

The present application has been devised in view of this fact, and the purpose is to obtain a tray that can be easily manufactured without requiring labor and labor, and can be provided at low cost without causing the cut items to slip or move. It is something to do.

In a multi-sided corrugated cardboard sheet in which a corrugated medium 4 is sandwiched between an intermediate paper 1 and a back liner 2, and a corrugated medium 3 is attached to the top surface of the waste paper, a front liner is placed on top of the medium 3 on the top surface. The medium is exposed without providing a surface, and the sheet is cut into an appropriate shape such as a rectangle to form a packaging seat plate.

Functions and Effects The method of use of this application is to use this tray as a seat plate, place any item 6 such as canned food on it, cover the entire tray and item with a synthetic resin sheet 5, and then heat the sheet. It is conventional practice to tightly seal and package items by shrinking them.

In the present application, since the relatively thin corrugated medium 3 made of paper is exposed without providing a smooth liner on the top surface, when an item such as a canned product is dropped from above and placed on the item, the ridged edge crab medium 3 on the bottom side of the item is exposed. Insert into the 30 wave pattern.

Therefore, the packaging can be carried out reliably without the items slipping or moving or colliding with each other.

Therefore, it is necessary to provide a surrounding plate around the corrugated cardboard sheet to prevent the movement of the item. Since there is no need for any surrounding plates, manufacturing materials can be saved and the product can be provided at a low price.
