Description

  The present invention relates to a pulp mold tray (a tray made of papermaking board) provided with a fruit housing recess for housing fruits such as pears, peaches, tomatoes, apples and melons. The pulp mold tray of the present invention is, for example, immersed in a pulp solution by a molding die (a molding die having a convex portion corresponding to a fruit-accommodating concave portion on the mold surface and provided with a metal mesh on the mold surface) from the back side of the metal mesh. After sucking, it is obtained by taking out from the pulp solution, removing the undried product adhering to the wire mesh surface from the wire mesh surface, placing it on the table with the opening side of the fruit housing recess down and drying it. .

Pulp mold tray (paper-made paperboard tray) with multiple fruit storage recesses of a size and shape suitable for the fruit to be stored (pear / peach / tomato / apple / melon etc.) inside the tray Is well known.
In addition, the pulp mold is immersed in a molding die (a molding die having a convex portion corresponding to a fruit-accommodating concave portion on the mold surface, and a metal mesh is provided on the mold surface) and sucked from the back side of the metal mesh, and then taken out from the pulp solution. Also known is a production method for obtaining a pulp mold tray by removing an undried product adhering to the wire mesh surface from the wire mesh surface, placing the fruit-containing recess on the table side and drying it. .

In JP-A-2005-066766 (Patent Document 1), the shape of a concave portion (a portion corresponding to the fruit-accommodating concave portion of the present invention) that accommodates fruits and the longitudinal sectional shape of the side wall portion of the concave portion are linear. And forming the overall shape of the recessed portion so as to form a substantially inverted truncated cone shape, thereby expanding the area of the portion where the fruit is locked in the recessed portion, and the conventional fruit packaging A pulp mold tray for fruit packaging is described which eliminates the presence of shoulders (bents close to 90 ° of the opening edge) present in the container, thereby preventing fruit damage. .
Japanese Patent Laying-Open No. 2005-066766.

  As illustrated in FIG. 1, the pulp mold tray immerses the molding die 11 in the pulp solution 91 in the tank 90 and sucks it from the back side of the molding die surface (wire netting surface) so that pulp fibers are about 1 to 5 mm in the entire area. Then, the mold 11 is pulled up from the pulp solution 91 (arrow a), and the undried product adhered and formed over the entire area of the mold surface is opposed to the mold surface by the receiving mold 21. It is obtained by receiving (arrow b), further transferring from the receiving mold 21 onto the pallet 31 and feeding it to the dryer 40 (arrow c), and heating and drying in the dryer 40. Reference numeral 10 denotes a rotary mold support device, 20 denotes a rotary receiving support device, and 30 denotes a transport device.

  In the above, the undried product transferred onto the pallet 31 to be sent to the drying process is not the back side where the contact area with the pallet surface is small, but the front side where the contact area with the pallet surface is large faces downward. Then, it is transferred onto the pallet 31. That is, it is not transferred onto the pallet 31 so that the opening of the fruit receiving recess 51 faces upward as shown in FIG. 2B, but the opening of the fruit receiving recess 51 is lowered as shown in FIG. Is transferred onto the pallet 31 so as to face. The reason for this is that, as shown in FIG. 2B, in an undried state, the portion that is not supported by the pallet 31 hangs down and deforms as shown by a two-dot chain line, and the deformed shape is fixed and dried. It is left behind. For this reason, as shown in FIG. 2A, the contact area supported by the pallet 31 is made as large as possible, thereby minimizing the deformation of the product.

  However, when the front side is faced downward, that is, when the opening of the fruit accommodating recess 51 is transferred downward as shown in FIG. 2A, the pulp mold tray is improved in order to improve the peelability of the laminated pulp mold trays. The force concentrates on the stopper S formed at an appropriate part on the front side (the part illustrated by the hatched portion in FIG. 2A) and deforms like a two-dot chain line, and the deformed shape is fixed as it is after drying. Such as being left behind.

The stopper S is a plate-like part standing at an appropriate position of the pulp mold tray so that the laminated pulp mold trays do not overlap exactly. That is, for example, the pulp mold tray is shipped in a state where about 50 sheets are stacked, so when using, take out one by one from the top layer one by one with a mechanical device (a mechanical device with claws), It is necessary to provide fruit storage work. At this time, if the pulp mold trays are exactly overlapped with each other, there is no gap between the second sheet and the second sheet to take out the uppermost layer, which causes an obstacle to the removal operation. For this reason, a stopper is formed at an appropriate portion and a slight gap is provided between the respective layers to facilitate the peeling operation.
The present application aims to prevent the stopper from being deformed.

A pulp mold tray 50 characterized by that.
For example, in the example of FIG. 4, a plurality of fruit receiving recesses 51 are formed so that a total of five rows of six, five, six, five, and six in the long side direction of the tray 50 is formed. Is arranged.
Alternatively, in the example of FIG. 4, three, two, three, two, three, two, three, two, three, two, in the short side direction of the tray 50 are separated. In other words, a plurality of fruit accommodating recesses 51 are arranged so that there are three rows in total of 11 rows.

In means 1 or means 2,
The base surface 520 of the inter-recess base 52 is a small area.
A pulp mold tray 50 characterized by that.
When the area of the base surface of the base part between the recesses surrounded by the three or four fruit receiving recesses is somewhat large, the base surface upper wall body can be erected so as to circulate along the edge of the base surface. That is, the base surface upper wall body can be formed so as to have a ring-like shape when viewed from above. Since the base-surface upper wall body having such a shape has a certain degree of strength, even if the force concentration as described above is generated in the drying process, the deformation can be avoided. Therefore, the small area in the means 3 means that the area is so small that it is impossible to form such a closed-top base wall.
For example, when 28 fruit accommodating recesses 51 are arranged in a dense state on a tray having a size of about 43 cm × 31 cm, which is square when viewed from above (see FIG. 4), the area of the base surface is referred to here. It corresponds to a small area. When the size of the tray is about the above, about 6 to 30 fruit receiving recesses correspond to the small area range in the means 3.
In the means 1 and means 2 described above, it is a matter of course that the table surface 520 of the inter-recess base 52 is larger than the small area referred to by the means 3.
[4] Means 4:
In any one of means 1 to means 3,
The upper surface 540 of the boundary portion 54 is formed so as to be lowered from the base surfaces 520 and 520 of the inter-recess pedestal portions 52 and 52 at both ends, and the height of the upper boundary wall body 55 is lowered together with the upper surface 540 on which it is erected.

A pulp mold tray 50 characterized by that.
The height at which the upper surface 540 falls below the base surface 520 is illustrated as H2 in FIG.
[5] Means 5 (see FIG. 5):
In any one of means 1 to means 4,
The standing height H1 of the boundary upper wall body 55 is formed lower than the standing height H0 of the table top wall body 53.
A pulp mold tray 50 characterized by that.

The means 1 is a pulp mold tray 50 in which a plurality of fruit accommodating recesses 51 are arranged, and any one or two of the inter-recessed base portions 52 surrounded by three or four fruit accommodating recesses 51 are provided. The base-surface upper wall 53 is erected from the base surface 520 of the inter-recess base 52, and the boundary is formed from the upper surface of any one or two or more boundary portions 54 in the boundary portions 54 of the two fruit-receiving concave portions 51. The upper wall body 55 is erected, and the upper surface wall body 53 and the upper boundary wall body 54, and the inter-recessed base section 52 and the boundary section 54 in which they are erected are in a continuous state. 53 and the upper boundary wall body 55 are made continuous, so that the upper wall body 53 and the upper boundary wall body 55 have sufficient strength. For this reason, even if the force from the pallet 31 side concentrates in the drying process, they can be prevented from being deformed, and problems caused by the deformation (eg, peeling failure, etc.) can also be prevented. In addition, since it has sufficient strength against bending and pulling in the direction where the upper wall of the base and the upper wall of the boundary are continuous, when holding the edges at both ends of the direction in the state of containing the fruit Can sufficiently withstand bending. Moreover, even when the force which pushes a fruit in the said direction acts on the vibration etc. at the time of transport etc. which accommodated the fruit, it can fully endure.
The means 2 is a pulp mold tray 50 in which a plurality of fruit-accommodating recesses 51 are arranged continuously or separately in a predetermined direction so as to form a plurality of rows, and includes three or four fruits. The base surface upper wall 53 is erected from the base surface 520 of the inter-recess pedestal portion 52 that is surrounded by the accommodating concave portion 51 and is along one or more rows in the plurality of rows. The upper surface 540 of the boundary portion 54 of the boundary portion 54 of the two fruit accommodating recesses 51, which is continuous with the inter-recess base portion 52 where the upper surface 53 of the table surface is erected and along the row along which the inter-recess portion base portion 52 extends. The upper boundary wall 55 is erected from the upper surface, and the upper surface 53 of the base surface, the upper boundary wall 55, and the inter-recessed base portion 52 and the boundary portion 54 on which they are erected are continuous. Since the wall body 53 and the upper boundary wall body 55 are made continuous, the upper surface wall body 53 and the upper boundary wall body Body 55 has a sufficient strength. For this reason, even if the force from the pallet 31 side concentrates in the drying process, they can be prevented from being deformed, and problems caused by the deformation (eg, peeling failure, etc.) can also be prevented. Further, in the direction substantially along the continuous or separated arrangement direction of the fruit accommodating recesses 51, which is the direction in which the direction in which the base surface upper wall body 53 and the boundary upper wall body 55 continue is substantially along. More sufficient strength against pulling and pulling. For this reason, even when the edges at both ends in the direction are held by hand in a state where the fruit is accommodated, it is possible to withstand the bending more sufficiently. Moreover, even when the force which pushes a fruit in the said direction acts for the vibration etc. at the time of transport etc. which accommodated the fruit, it can fully endure.
In the pulp mold tray 50 of the means 3, the base surface 520 of the inter-recessed base part 52 has a small area in the means 1 or means 2, so that the upper surface of the base surface is formed in a ring shape in a top view, for example. Even when the deformation avoidance measure cannot be adopted, it is possible to prevent the upper surface wall body 53 and the upper boundary wall body 55 from being deformed in the drying process, and to deform as such. It is also possible to prevent problems caused by the problem (eg, peeling failure).
The pulp mold tray 50 of the means 4 is formed so that the upper surface 540 of the boundary portion 54 is lowered from the base surfaces 520 and 520 of the inter-recessed base portions 52 and 52 at either end in any of the means 1 to means 3, Since the height of the boundary upper wall 55 is formed so as to be lowered together with the upper surface 540 on which it is erected, the upper edge of the boundary upper wall 55 is formed on the fruit accommodated in the fruit accommodating recess 51 and transported. The contact can be prevented and the damage can be prevented.
The pulp mold tray 50 of the means 5 is formed in any one of the means 1 to means 4 such that the standing height H1 of the boundary upper wall body 55 is lower than the standing height H0 of the table top wall body 53. Therefore, the effect of the means 4 can be further enhanced.

Embodiments of the present invention will be described with reference to the drawings.
(1) Manufacturing process:
FIG. 1 shows an example of a manufacturing process of a pulp mold tray (a tray made of papermaking paper board).
As shown in the figure, when the arms of the rotary mold support device 10 are rotated at a constant speed in the direction of arrow a, the mold 11 attached to the tip of each arm is moved to the pulp solution 91 in the pulp solution tank 90. Soak in order. Each mold 11 is provided with a mold surface made of wire mesh, and the shape thereof matches the shape of the front side of the pulp mold tray to be manufactured (the opening side of the fruit accommodating recess 51). Has been. While the mold 11 is immersed in the pulp solution 91, vacuum suction is performed from the back side of the mold surface. Thereby, pulp fiber adheres to the whole region of the mold surface made of wire mesh. The molding die 11 is pulled up from the pulp solution 91 at a timing when the thickness of the attached pulp fiber becomes about 1.5 mm. In addition, this adhesion thickness is determined according to the tray to be manufactured, and has a slight width (about 1 to 5 mm).

The rotary receiving support device 20 is operated in the direction of arrow b at a constant speed synchronized with the rotary mold support device 10, and a receiving die 21 is provided at the tip of each arm of the rotary receiving support device 20. Is attached.
The mold 11 pulled up from the pulp solution 91 as described above is opposed to the receiving mold 21 that is sequentially positioned at a predetermined facing position by the rotary receiving support apparatus 20. At the time of facing, extrusion air is discharged from the back side of the mold 11, while vacuum suction is performed from the back side of the receiving mold 21. For this reason, the pulp fibers (undried pulp mold tray) adhering to the mold surface of the mold 11 are transferred to the receiving mold 21.

Thus, the pulp fiber (undried pulp mold tray) delivered to the receiving mold 21 is carried to a position above the pallet 31 of the conveying device 30 while being supported by the receiving mold 21 and transferred onto the pallet 31. Is done. As shown in FIG. 2A, the transfer is performed such that the front side (the side of the opening of the fruit accommodating recess 51) faces downward. At this time, the top of the base surface upper wall body 53 (FIG. 3 etc.) abuts on the pallet 31, but the base surface upper wall body 53 is continuous with the boundary upper wall body 55 (FIG. 3 etc.) and has sufficient strength. Have. For this reason, deformation is also prevented.
The undried pulp mold tray transferred onto the pallet 31 is transported in the direction of arrow c by the transport device 30 and sent to the drying device 40 where it is heated and dried in the drying device 40.
In this way, a pulp mold tray is manufactured.

(2) Pulp mold tray 50:
3 to 5 show a tomato pulp mold tray 50 provided with 28 fruit accommodating recesses 51, FIG. 3 is a perspective view (and a partially enlarged view), FIG. 4 is a top view, and FIG. ) Is a cross-sectional view taken along line AA in FIG. 4, (b) is a cross-sectional view taken along line BB, (c) is a cross-sectional view taken along line CC, and (d) is a cross-sectional view taken along line DD. In addition, the hatching part in FIG. 4 shows the upper surface (top part) of the base surface upper wall body 53 and the boundary upper wall body 55 instead of a cross section. 5D is not a section cut along a straight line, but is a curve connecting the base surface upper wall body 53 and the boundary upper wall body 55 in FIG. 4 (as shown by a one-dot chain line in FIG. 4). It is a cross section cut along the curve shown.

  The illustrated pulp mold tray 50 has an inner shape (inner shape in a top view; rectangular shape) of a box (eg, a cardboard box) that is accommodated together with tomatoes that are fruits to be accommodated when the pulp mold tray 50 is transported or the like. It is an external shape (external shape in top view; rectangular shape) and size (example: “43 cm × 31 cm” or so), and a total of 28 fruit accommodating recesses that are recessed with respect to the surrounding edge surface. 51 is arranged in a close position in a dense state.

  Thus, since many fruit accommodation recessed parts 51 are arrange | positioned in the dense state, the area (base surface upper wall body) of the base surface 520 of the base part 52 between recessed parts formed in the site | part enclosed by the three fruit accommodation recessed parts 51 The area including the portion hidden by 53) is about “1.8 cm × 1 cm × 1/2”. In addition, the width of the upper surface 540 of the boundary portion 54 of the two fruit accommodating recesses 51 (the width including the portion hidden by the boundary upper wall body 55 when the boundary upper wall body 55 is present) is the fruit aligned in the long side direction of the tray. It is about “1.2 cm” in the case of between the accommodation recesses (between the fruit accommodation recesses adjacent in the horizontal direction in FIG. 4), and about “0.8 cm” in the case of between the fruit accommodation recesses adjacent in the oblique direction. That is, both are relatively small.

  Since the area of the base surface 520 of the base part 52 between the recesses is small as described above, the base surface upper wall body is formed on the base surface 52 so as to circulate around the edge of the base surface 52 and is completed on the base surface 520. It is not possible to form (the upper wall of the base surface having sufficient strength that does not deform in the drying step).

  The boundary portion 54 is set such that the upper surface 540 is lowered from the base surface 520 of the inter-recessed base portion 52 located at both ends of the boundary portion 54, and the upper surface of the boundary portion 54 and the base surface 520 of the inter-recessed base portion 52 The height difference H2 (see FIG. 5D) is about “0.6 cm”. The reason why the height of the boundary portion 54 is thus lowered is to prevent damage to the tomato accommodated in the fruit accommodating recess 51. That is, even when vibration is applied to the tomato during transportation or the like, the tomato does not strongly touch the boundary portion 54 to prevent the damage.

In the illustrated pulp mold tray 50, as shown in FIG. 4, a base surface upper wall 53 is erected from the base surface 520 of each inter-recess base 52, and the long side of the tray is formed with respect to each inter-recess base 52. The upper boundary wall body 55 is erected from the upper surface 540 of each boundary portion 54 that is continuous in the direction substantially along the direction, and these are continuous with each other. That is, as shown in FIG. 4, from the inter-recess base portions 52 and the respective boundary portions 54 along the rows of the fruit-accommodating recess portions 51 arranged in a plurality of rows continuously arranged in the tray long side direction. A base surface upper wall body 53 and a boundary upper wall body 55 are erected and are continuous with each other. Thus, since each table | surface upper wall body 53 and the boundary upper wall body 55 along the row | line | column of the fruit accommodating recessed part 51 of tray long side direction are continuing, each table | surface upper wall body 53 is the pallet 31 by the above-mentioned drying process. The tray has a sufficient strength so as not to be deformed even if it comes into contact with the tray. In one of the two directions), it will have sufficient strength against bending and pulling. Can withstand enough. Moreover, even when the force which pushes a fruit in the said long side direction acts for the vibration etc. at the time of transport etc. which accommodated the fruit, it can fully endure.
In the example shown in the figure, since the base surface upper wall body 53 and the boundary upper wall body 55 are made continuous in a direction substantially along the tray long side direction, it has sufficient strength against bending and pulling in the long side direction. However, when it is continuous in the tray short side direction, it has sufficient strength against bending and pulling in the short side direction, and when it is continuous in the tray diagonal direction, Of course, it has sufficient strength against bending and pulling.
In addition, since the arrangement | sequence of the fruit accommodation recessed part 51 in a tray short side direction becomes remote when the fruit accommodation recessed part 51 is arrange | positioned in an insertion position like illustration, in the arrangement | sequence of the fruit accommodation recessed part 51 of a tray short side direction When the base surface upper wall body 53 and the boundary upper wall body 55 are made continuous in the direction along, the continuous line forms a zigzag shape or a trapezoidal pulse shape having a swing width of about ½ of the opening diameter of the fruit accommodating recess 51. It will be.

  In the above description, the standing height (the height from the base surface 520 to the top of the base surface upper wall 53) H0 (see FIG. 5D) of the base surface upper wall body 53 is substantially “6 mm”. Further, the standing height of the upper boundary wall body 55 (height from the upper surface 540 of the boundary section 54 to the top of the upper boundary wall body 55) H1 (see FIG. 5D) is substantially “4 mm”. Thus, since the standing height of the boundary upper wall body 55 is set lower than the standing height of the table top wall body 53, the above-described damage prevention effect of the tomato accommodated in the fruit accommodating recess 51 is further increased. Can be increased.

Since the pulp mold tray 50 of the present example is configured as described above, even if the top of the base surface upper wall body 53 abuts against the pallet 31 of the transport device 30 in the drying process, the deformation can be prevented, and is good. The pulp mold tray 50 including the base surface upper wall body 53 and the boundary upper wall body 55 can be manufactured. Therefore, even in the present situation where a large number of pulp mold trays 50 are stacked and shipped, a slight gap can be surely secured between the layers of the pulp mold tray 50, which hinders the peeling operation by the user's mechanical device. Never happen.
Further, since the shoulder portion of the boundary portion 54 and the top portion of the boundary upper wall body 55 are sufficiently low, the tomato, which is a container, is strongly attached to the shoulder portion of the boundary portion 54 and the top portion of the boundary upper wall body 55 during transportation. Touching can be prevented, and damage can be prevented.
Further, since the upper table wall 53 and the upper boundary wall 55 are continuous along the direction of the long side of the tray, which is one of the arrangement directions of the fruit receiving recesses 51, the bend in that direction is continued. Sufficient strength against tension. For this reason, even when the edges of both ends in the long side direction are held by hand in a state in which the fruit is accommodated, it is possible to more fully withstand bending. Moreover, even when the force which pushes a fruit in the said long side direction acts for the vibration etc. at the time of transport etc. which accommodated the fruit, it can fully endure. For this reason, the accommodation fruit is not damaged.

In the example of FIGS. 3 to 5, the base surface upper wall body 53 and the boundary upper wall body 55 which are erected from the base surface 520 of the inter-recess base portion 52 and the upper surface 540 of the boundary portion 54 which are continuous in the tray long side direction are continuously provided. For this reason, the tray has a sufficient strength against bending and pulling in the direction of the long side of the tray, but the present invention is not limited to a method of continuous in such a direction.
For example, as shown in FIG. 6 (a), the base surface upper wall body 53 and the boundary upper wall body 55 may be erected from the base surface 520 of the base portion 52 between the recesses and the upper surface 540 of the boundary portion 54 so as to be continuous. As shown in (b), the base surface upper wall body 53 and the upper boundary wall body 55 are continuously provided from the base surface 520 of the inter-recessed base portion 52 and the upper surface 540 of the boundary portion 54 arranged in the short side direction of the pulp mold tray. May be. When continuous in this way, it has a particularly sufficient strength against bending and pulling in the continuous direction.

  Moreover, in the example of FIG. 3 etc. which arrange | positions the fruit accommodation recessed part 51 in an insertion position, on the base surface from the base surface 520 of each base part 52 between recessed parts arranged in the long side direction of a pulp mold tray, and the upper surface 540 of each boundary part 54, respectively. Even when the wall body 53 and the upper boundary wall body 55 are erected and continuous (in the case of FIG. 3 or the like), or the base surface 520 of the inter-recess base section 52 arranged in the short side direction and the upper surface 540 of each boundary section 54. Even if the upper surface 53 and the upper boundary wall 55 are erected and continuous (not shown), they continue in a meandering state, zigzag shape, or trapezoidal pulse shape.
