Abstract

PROBLEM TO BE SOLVED: To provide a pack for packaging fruits which can eliminate the problem of blocking. SOLUTION: In the pack for packaging fruits 1 of automatically feedable type comprising a foamed thermoplastic resin sheet, in which a large number of recesses 2 for storing fruits are formed so as to project downward, projection 3 are formed on or near the upper end of a protruding side of the sheet being the rear side of the recess 2 for storage to prevent blocking when the pack is stacked one on another.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic supply type fruit packaging pack, and more particularly, to a method for supplying fruits such as apples and pears with an automatic supply machine without blocking as a fruit packaging tray. We are trying to provide products that can be supplied one by one.

[0002]

2. Description of the Related Art Conventionally, as a fruit packaging pack, a molded article made of a foamed polystyrene resin sheet or a pulp mold has been mainly used (for example, Japanese Utility Model Publication No. 3-8630).
No. 6-18947). Producers and agricultural cooperatives in production areas mainly packed fruits such as apples and pears into these fruit packing packs.

[0003] However, due to labor shortage, labor cost reduction and integration by agricultural cooperatives, the use of automatic fruit sorting machines for fruits is increasing, and there is a situation where fruits and packs use automatic feeding machines. is there. For fruit packing packs, there was no problem if they were separated into individual packs even if they had been blocked (overlapping state) in the case of manual fruit filling so far. When using is required, it is necessary to eliminate blocking. Because, in the case of an automatic feeding machine, a method is adopted in which a pack is suctioned by vacuum force and inserted into a transport box. This is because it causes trouble.

[0004] In the present invention, it is possible to provide a fruit packaging pack capable of solving such a blocking problem.

[0005]

According to a first aspect of the present invention, there is provided a fruit packaging pack according to the present invention for solving the above-mentioned problems caused by blocking. A fruit packaging pack made of a plastic resin foam sheet, wherein a protrusion is formed to prevent blocking during stacking downward from the upper end or the vicinity of the upper end of the protruding surface on the back side of the storage recess. Features.

According to the fruit packaging pack of the first aspect, the protrusion for preventing overlap during stacking is not formed from the upper end on the front side of the recess for storage, but from the upper end or near the upper end of the projecting surface on the back side. Since it is formed downward, the upper surface of the lower pack is surely stopped by the protruding portion at the time of stacking, so that blocking is reliably prevented.

In particular, according to a second aspect of the present invention, a plurality of protrusions for preventing overlap are formed on a protruding surface on the back side of one storage recess. The anti-blocking action of each pack can be achieved in a well-balanced manner.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be sequentially described below with reference to the drawings. FIG. 1 is a front view showing an automatic feeding-compatible type fruit packing pack according to the present invention, FIG. 2 is a bottom view, and FIG. 3 is a cross-sectional view thereof. It is formed of a foamed polystyrene sheet, and is formed in a rectangular shape so that the outer shape is adapted to the transport box. In the case of the above figure, twelve storage recesses 2 are placed below the sheet so that twelve fruits can be stored. Projection is formed.

Three projections 3 are formed downward from the upper end of the projection surface 20 on the back side of the storage recess 2 to prevent blocking during stacking.
It is preferable to form a plurality, preferably 2 to 4, of them in order to prevent blocking. Further, the protrusion 3 does not necessarily need to be formed from the upper end of the protruding surface 20 and may be formed from a position slightly lower than the upper end. Since it is not formed from the upper end, when the packs 1 and 1 are stacked, the upper surface 4 of the pack 1 on the lower side is always stopped by the projection 3 to prevent blocking.

The shape of the projection 3 is not limited to that shown in the figure. For example, as shown in FIG. The dimensions of the protrusion 3 in the embodiment of FIGS. 1 and 4 are 5 mm to 10 mm in width, 5 mm to 15 mm in height,
A protrusion degree of about 1 to 5 mm is a practically preferable range. However, it is also possible to form the projection 3 in a ring shape as shown in FIG. 5 or a considerably wide shape as shown in FIG. 6, and in these cases, the width dimension is significantly larger than the above-mentioned range. Although it is large, blocking can be prevented without any problem in the overall balance.

Further, of the total number of storage recesses 2,
The part that forms the protrusion 3 and the part that does not form the protrusion may be mixed, and in this case, a part in which the formation of the protrusion 3 is omitted may be provided in a range that does not affect blocking prevention. In addition, as long as the sheet used as the material of the pack 1 is a foamed thermoplastic resin sheet, any foamed sheet other than the foamed polystyrene sheet does not cause any problem in practice.

[0012]

As described above, according to the fruit pack of the present invention, the pack is formed from the upper end or the vicinity of the upper end of the protruding surface on the back side of the storage recess. Blocking during stacking can be surely prevented, so that it can be applied to automatic supply by vacuum suction of each pack, and an excellent effect of reliably avoiding trouble due to blocking can be exhibited.
