DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a holding and supporting means for individually fitting and supporting packaging trays for storing and storing foods such as vegetables, fruits and eggs and various precision parts. The present invention relates to a frame, and more particularly, to a packaging tray holding frame capable of stacking by fitting columns when not in use and forming a space for holding the tray by connecting the columns when used.

[0002]

2. Description of the Related Art Conventionally, fruits such as strawberries, loquats, cherries, grapes and plums, small vegetables such as mini tomatoes, and various small precision parts are stored in a synthetic resin packaging tray having a flange on the periphery of an opening. The tray is further stored and transported in a cardboard box. At a retail store such as a supermarket, the tray is taken out of the cardboard box and displayed at the store as it is for sale. In a factory that assembles products using small precision parts, the tray is taken out of a cardboard box and supplied to the assembly line as it is. For example, if you explain the distribution route of strawberries from the producer to the retail store,
Strawberries collected by the producer are first sorted for each designated size, and then stored in a tray as shown in FIG.

The tray 1 shown in FIG. 7 has a generally widely used shape, and has a flange 2 at the periphery of an upper opening, and a storage portion 3 has a tapered surface such that the peripheral wall is narrowed toward the bottom. Is formed. After storing the strawberries collected in these trays 1 for each specified size, the top surface is covered with a film showing the name of the place of production, and four trays are placed in parallel in the assembled cardboard box, and four trays are further placed. A cross-shaped partition is inserted to isolate each.

[0004] Since the trays cannot be stacked, only four trays can be placed in a single cardboard box. The strawberries put in the cardboard box in this way are brought to a pickup place and 100% inspected. When the inspection is completed, the cardboard boxes containing the four trays are stacked in five stages and bound together by banding.

[0005] The five-tiered cardboard boxes, which are united together, are temporarily stored in a pre-cooled refrigerator and then transported to a fruit and vegetable market by an insulated truck. After being put on auction in the vegetable market in the same way as ordinary vegetables and fruits, it is sold at retail stores such as supermarkets. At the fruit and vegetable market, the band tying the cardboard boxes must be cut off for selling, and the cardboard boxes must be opened and the trays containing strawberries removed for sale at retail stores.

[0006]

However, the above-mentioned conventional transportation methods have the following problems. That is, in order to put the tray in the cardboard box, the cardboard box must first be assembled. However, assembling a large number of cardboard boxes is troublesome and time-consuming, and places a heavy burden on the producer. In addition, since cardboard boxes are disposable and cannot be reused, they will be discarded as an enormous amount of garbage, which leads to the disposal of the garbage and the destruction of the global environment by wasting natural resources. It has become a social problem.

Further, since the cardboard box becomes almost sealed when the lid is closed, the air circulation between the inside and outside deteriorates. The temperature could not be kept cool, or the temperature could not be kept uniform. In order to improve the circulation of cold air, it is necessary to increase the spacing between the rows of cardboard boxes that are stacked when loading them into a cool car.However, this is not always sufficient. There is a problem of inefficiency.

[0008] In addition, the cardboard boxes are not stable simply by being stacked, and are inconvenient to carry.
Five cardboard boxes are bound together by banding. For this reason, an automatic tying machine has to be provided, which is not only troublesome to put into the tying machine but also increases the cost due to the fact that the cardboard box is disposable. In addition, in the fruit and vegetable market, a lot of garbage is generated, along with the trouble of cutting the band to put it on the auction. Also, in a retail store such as a supermarket, the cardboard box is not dismantled in the store because small dust and dust are generated when dismantled. Therefore, there is a problem that dismantling work must be performed in a storage place such as a warehouse.

The present invention has been made in view of the above situation, and is intended to be used by filling in a synthetic resin box. It is easy to handle, and is fitted and stacked when stored. Takes up no space, just 1 for use
It is an object of the present invention to provide a packaging tray holding frame capable of securing a space for fitting and holding a tray simply by rotating the tray by 80 degrees.

[0010]

The present invention has the following configuration to achieve the above object. That is, the packaging tray holding frame of the present invention, a plurality of hollow cone-shaped pillars are erected on a frame formed by forming a plurality of windows by bars provided vertically and horizontally,
The hollow conical strut penetrates the frame, at least the frame-side end surface is open, and is arranged so as to be alternately opposite in the same row direction with the frame interposed therebetween. . It is preferable that a concave portion is provided between the hollow conical columns on the side surface of the horizontal rail. Further, the hollow cone-shaped support can be formed by a truncated cone-shaped or a truncated pyramid-shaped hollow cone-shaped support. Further, a projection is provided at the tip of one upward hollow cone-shaped support column equidistant with respect to the center line in the plane, and a hole is provided at the tip of the other downward hollow cone-shaped support column. It is preferable that the protrusions are formed so as to fit into the holes when one of the holding frames is horizontally rotated by 180 degrees and stacked. And
