Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mushroom storage container which is formed in a box shape having an open upper surface and in which a plurality of mushrooms are arranged and stored in a horizontal direction. It is suitably used as a container for accommodating mushrooms such as eryngii and matsutake mushrooms having a relatively long handle.

[0002]

[Background Art] Mushrooms produced in large quantities by artificial cultivation are stored in packaging bags or trays in fixed quantities, sealed, and shipped.
It is sold to consumers while maintaining freshness after shipment. Here, among various mushrooms, mushrooms, shiitake mushrooms, etc., whose bulk size is relatively large compared to the length of the handle, are stored in such a form that the bulks are arranged on a tray with an open top, and wrapped. Usually, packaging is performed so as to cover the opening portion.

On the other hand, for mushrooms such as eryngii, matsutake mushrooms, etc., which have a relatively large width and the length of the handle is relatively longer than the width of the bulk, the extending direction of the mushrooms should be aligned in a box-shaped tray. It is usual to take a method of storing and enclosing each tray in a hermetically sealed bag with a resin bag. In addition, if the size of the handle is sufficiently small compared to the length of the pattern such as enoki, it may be sealed in a packaging bag, but it is stored in a box tray like an eringi etc. It may be hermetically sealed.

[0004]

However, such a method of storing mushrooms in a box-shaped tray in which the directions of extension are arranged side by side is a method of packing the mushrooms in a state in which the mushroom portion is in contact with the bottom surface of the box-shaped tray. Therefore, there is a problem that the bulk portion is broken due to vibration during transportation or the like, and the product value is reduced when selling at a store such as a supermarket.

[0005] An object of the present invention is to provide a mushroom storage container in which the bulk of the box-shaped container does not break even when the mushrooms are stored in such a manner that the extending directions are aligned horizontally.

[0006]

In order to achieve the above object, a mushroom storage container according to the present invention is formed in a box shape having an open upper surface, and has mushrooms arranged and stored therein in the direction of extension horizontally. A mushroom storage container, wherein a convex ridge extending along the direction in which the mushrooms are arranged is formed on a bottom surface of the container located on the bulk side of the center of gravity of the mushroom to be stored in the extending direction. I do.

Here, various materials can be used as the material of the container. However, in view of the fact that mass production is possible at low cost, it is preferable to use a thermoplastic resin. HIPS (Hi
gh Impact PolyStyrene), GPPS (General Purpose)
type PolyStyrene), OPS (Oriented PolyStyren)
e), PET (Polyethylene Terephthalate), APE
T (Amorphous Polyethylene Terephthalate), PP
(PolyPropirene), PP containing filler, and the like are preferably used. Further, a foamed resin such as foamed polystyrene may be used as the material of the container.

As a method of molding with such a thermoplastic resin, a method of vacuum-forming, pressure-forming, vacuum-pressure-forming the raw sheet of the thermoplastic resin, and a method of injection-molding the thermoplastic resin are considered. Can be The thickness of the container is typically 0.1 mm to 1.0 mm when a sheet or the like is formed.
Although it is mm, in consideration of product cost, it is more preferably 0.2 mm to 0.5 mm, and when the wall thickness is thin, the container bottom part and a part of the side wall part are deformed in the out-of-plane direction as necessary. It is preferable to form a reinforcing rib or the like. When foamed polystyrene or the like is selected as the material of the container, the container thickness is 1
mm or more and has sufficient strength, so that such a reinforcing rib is unnecessary.

[0009] The outer cross-sectional shape of the ridge is circular,
Although various shapes such as a trapezoidal shape can be adopted, a shape having a flat portion that comes into contact with the mushroom handle portion in surface is preferable. Further, for example, in the case of eryngii or the like, it is preferable to have a height of 7.5 mm to 17.5 mm from the bottom of the container. The position of the protruding ridge portion may be any position as long as it is on the bulk side of the center of gravity of the mushroom in the extending direction, and more preferably, it is 24 mm to 34 mm from the end of the container on the mushroom bulk side.

According to the present invention, the mushroom storage container has the convex ridge formed on the bottom surface of the container.
The mushroom to be stored is in contact with the handle portion, and the bulk portion is held in a state of floating from the bottom portion. Therefore,
Even if vibration or the like acts during transportation, the bulk portion is not damaged and the commercial value is not reduced. When the ridge portion has the above-described dimensions, it is suitable as a container for storing eryngii.

[0011] In the above, it is preferable that the above-mentioned ridge portion is formed integrally with a part of the container bottom portion protruding inside the container. Such a ridge can be easily formed by forming a ridge on the surface of a mold used for vacuum forming or the like.
According to the present invention, since the projecting portion is formed by partially deforming the container, the projecting portion can be formed simultaneously with the molding of the container, and the manufacturing cost of the container can be greatly reduced. Also,
Because the ridge also has a role as a rib for container reinforcement,
Container strength can be improved.

[0012] In the above-mentioned mushroom storage container, it is preferable that the depth of the container is larger than the width of the mushroom. By making the container depth dimension larger than the width dimension of the bulk in this way, when storing the mushrooms, the bulk portion does not protrude from the upper surface of the container, so after sealed packaging, stack the packages vertically. It is more preferable that the mushroom portion is not damaged.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. 1 to 3 show a mushroom storage container 1 according to an embodiment of the present invention. FIG. 1 is a plan view seen from the opening side of the container, and FIG. 2 is a II-II of FIG.
FIG. 3 is a sectional view taken along line III-III of FIG. The container 1 is formed in a box shape having an open top surface, and includes a container bottom portion 2 and a side wall portion 3 provided so as to surround the container bottom portion 2, and a side wall opposite to the container bottom portion 2. The portion surrounded by the portion 3 is an opening 4.

The container bottom portion 2 is formed in a substantially rectangular plane shape that is slightly smaller than the plane shape of the opening portion 4.
Slightly larger than the length of the mushroom to be stored, approximately 5
It is set to be 10% larger. Further, the dimension in the short side direction of the container bottom portion 2, that is, the arrangement direction of the mushrooms, can be an appropriate size depending on the number of mushrooms to be stored,
The dimensions are preferably such that the mushrooms can be stored in a row. As shown in FIGS. 2 and 3, the side wall portion 3 is formed in a slope shape that expands to the outside of the container toward the opening portion 4. A plurality of reinforcing ribs 11 are formed on the container bottom surface 2 and the side wall 3 along the long side direction and the short side direction of the container 1. The reinforcing rib 11 is formed in a semicircular cross section in which a part of the container bottom portion 2 and a part of the side wall portion 3 protrude inside the container, and extends from the container bottom portion 2 to near the upper end of the side wall portion 3.

At the corners of the container bottom 2 are formed oblique ribs 12 extending radially in a substantially diagonal direction of the rectangle of the container bottom 2. The oblique ribs 12 also have the same cross-sectional shape as the reinforcing ribs 11, and extend to the vicinity of the upper end of the intersection of the adjacent side wall portions 3. Further, in a portion surrounded by the reinforcing rib 11 and the oblique rib, an auxiliary rib 1 in which a part of the container bottom portion 2 and a part of the side wall portion 3 project outside the container 1
3 are formed along the extending direction of the reinforcing rib 11.

As shown in FIGS. 2 and 3, the upper end portion of the side wall portion 3 is formed with a turn-back portion 14 which is bent outward in a flange shape over the entire periphery of the container 1. Functions as a reinforcement for preventing the opening 4 from being deformed. Further, a film is thermally welded to the flat portion of the upper surface of the return portion 14 as necessary. However, when the film is thermally welded, the width is smaller than the width of the flat portion of the upper surface of the return portion 14 in FIGS. To ensure a large welding area.

On the container bottom 2 of the container 1 provided with such various reinforcements, there is formed a ridge 20 as shown in FIG. The ridge portion 20 is formed in a substantially trapezoidal cross section in which a part of the container bottom portion 2 is deformed inside the container, and includes a hypotenuse portion 21 and an upper surface portion 22. Ridge 20
Has a trapezoidal apex at a portion of dimension L from the intersection of the side wall 3 in the short side direction with the container bottom 2, has a height H from the inner surface of the container bottom 2, and the hypotenuse 21 is vertical The angle is inclined by θ ° in the direction.

These dimensions L and H can be appropriately changed depending on the mushroom to be stored. In the case of a container for storing mushrooms such as eringi, for example, L = 29 mm ± 5 mm,
H is set at 12.5 mm ± 5 mm. Further, the angle θ ° can be arbitrarily determined, but is set at about 39 ° ± 10 ° from the viewpoint of removing the mold during molding and ensuring surface contact with the stored mushrooms as much as possible. Also, the ridge 20
Is, as shown in FIG. 3, the short side direction side wall 3 of the container 1.
Along the long side direction side wall 3 as shown in FIG.
, The trapezoidal cross-section of the ridge 20 extends outward.

Such a container 1 has a thickness of 0.1 mm to
It can be manufactured by vacuum forming a 1.0 mm HIPS or GPPS sheet. First, a sheet is heated and softened by a heater while clamping the sheet end with a spike chain or the like. When the sheet is in a softened state that is optimal for molding, the sheet is placed in a chamber, and the sheet is brought into close contact with a mold by vacuum suction to be molded. still,
A plurality of container molds are arranged in parallel in the mold, and a plurality of containers are formed at a time by closely adhering a sheet of a predetermined size. In the mold, a concave portion or a convex portion is formed on a part of the surface forming the outer shape of the container 1. The concave portion is for forming the auxiliary rib 13, and the convex portion is for forming the reinforcing rib 11, the oblique rib 12, and the protruding ridge portion 20. At the same time, the ridge 20 is formed at the same time.
After completion of the molding, the container is cooled, cut into each container with a cutting blade or the like, and released.

Next, a method of using the above-described container 1 will be described. FIG. 4 shows a state in which the mushrooms 30 are stored in the container 1. In the container 1, a plurality of mushrooms 30 such as eryngii are arranged and stored with their extending directions aligned horizontally. Each of the mushrooms 30 is stored diagonally in the container 1 with the convex portion 20 as a pillow and the bulk portion upward. More specifically, as shown in FIG. 5, the ridge 20 is formed at a position on the bulkier side of the center of gravity M of the mushroom 30, and by forming the ridge 20 at such a position, Mushroom 30
Are stored diagonally with the bulk side facing upward.

The height H of the ridge 20 is the same as described above, but in short, the height H of the mushroom 30 is such that the lower end of the bulk of the mushroom 30 can be held in a floating state from the container bottom 2. I just need. As can be seen from FIG.
Is stored, the handle portion of the mushroom 30 substantially abuts on the upper surface portion 22 of the ridge 20. The depth dimension D of the container 1 is larger than the width dimension 30D of the mushroom 30, and
The upper end portion of the bulk is set so as not to protrude from the upper end of the side wall portion 3 of the container 1 in a state where the handle portion of the mushroom 30 is in contact with the zero. The container 1 in which the mushrooms 30 are stored is soft-wrapped with a film or the like, and is shipped from a production farmer while maintaining freshness, and is sold as it is at a store such as a supermarket.

According to the above-described embodiment, the following effects can be obtained. That is, since the projecting ridge 20 is formed on the container bottom portion 2 of the container 1, the mushroom 30 to be stored is such that the handle portion is in contact with the projecting ridge 20 and the bulk portion is the container bottom portion. 2 is kept floating. Therefore, even if vibration or the like acts during transportation, the bulk portion is not damaged, and the commercial value is not reduced. Also,
By forming the ridges 20 at the positions and dimensions as described above, a container suitable for mushrooms 30 such as eryngii can be obtained.

Further, since the protruding ridge portion 20 is formed integrally with a part of the container bottom surface portion 2 protruding inside the container,
The ridge 20 can be formed at the same time as the container is formed, and the manufacturing cost of the container 1 can be significantly reduced. Also, the ridge 2
Since 0 also has a role as a rib for reinforcing the container 1,
The strength of the container can be improved in addition to the reinforcing ribs 11 and the like. When the depth M of the container 1 is larger than the width 30D of the mushroom 30 to be stored, the mushroom 30 protrudes from the upper surface of the opening 4 of the container 1 when the mushroom 30 is stored. Since there is no mushroom 30, the bulk of the mushroom 30 is more preferable without being damaged.

Note that the present invention is not limited to the above-described embodiment, but includes the following modifications. In the above embodiment, the ridge 20 is formed in a trapezoidal cross section, but the present invention is not limited to this. That is,
In other words, the shape of the ridge 20 may be any of various shapes as long as the mushroom portion to be stored does not abut against the bottom of the container, and may have a circular or triangular cross section. Is also good. Further, in the above-described embodiment, the convex portion 20 is formed integrally with the container bottom portion 2 of the container 1. However, a rod-shaped member may be attached to the container bottom portion to form the convex portion.

Further, in the above embodiment, HIPS, G
Although the container 1 was formed by vacuum forming the PPS film, the forming method is not limited to this, and for example, injection molding or the like may be employed. And in the embodiment,
Although the container 1 was made of a film having a thickness of 0.1 to 1.0 mm, the present invention is not limited to this.
A container having a ridge may be formed by using P) or the like.
In this case, if the PSP is used, a container having a sufficient thickness can be obtained, so that it is not necessary to form a reinforcing rib or an auxiliary rib. In addition, specific structures, shapes, and the like at the time of carrying out the present invention may be other structures and the like as long as the object of the present invention can be achieved.
