Description

  In the present invention, a plurality of (about 3 to 9) recesses for accommodating relatively large fruits such as melons are regularly arranged, and the outer shape has a tray shape. The present invention relates to a pulp mold product used by being set in a cardboard box.

  When transporting relatively small sized fruits such as tomatoes, strawberries, pears, apples, peaches, etc., a plurality (5 to 5) for storing fruits is used for the purpose of preventing damage due to vibration during transportation. Fruits are accommodated in a soft tray having about 32 recesses, and the tray is set in a cardboard box and transported. Here, the inner shape of each recess is substantially the same as the outer shape of the lower half of the fruit to be accommodated, but there is a partition that protrudes upward from the opening height of each recess. Absent. In other words, if the fruits are relatively small and light, the upper half of the fruits are less likely to be damaged by contact with the fruits in the adjacent recesses, so the lower half of the fruits to be accommodated is separated. Only a recess that can be used is sufficient, and a partition wall for separating the upper half of adjacent fruits is unnecessary. In addition, pulp mold molded products and resin molded products are used as soft materials, but pulp mold molded products that are excellent in breathability and moisture absorption, recyclability and low environmental impact are more suitable. It is used.

  The desire to prevent damage due to vibration during transportation is not only for small-sized fruits but also for large-sized fruits such as melons. Rather, expensive melons are more demanding. However, since the weight increases as the size increases, there is an increased risk that the upper half of the fruit will come into contact with and damage the fruit in the adjacent recess due to vibration during transportation. As a technique for preventing this damage, as in Design Registration No. 1233597, a partition that protrudes upward from the opening height of the recess is provided between the adjacent recesses to prevent the fruit from contacting the both recesses. Can be mentioned.

  The partition wall protruding upward from the opening height of the recess can be manufactured by sucking and molding the outer surface side with a mold (soaking mold) instead of the inner surface side of the recess. In other words, when manufacturing a recess without a partition wall, the inner surface side is sucked and molded with a mold (soaking mold), but when there is a partition wall, the inner surface side is sucked and molded with a mold (soaking mold). Then, in the drying process, the inner surface side (= the side with the partition wall protruding from the opening height of the recess) is placed on the drying conveyor belt so that the force concentrates on the partition wall, and as a result In the undried state, it hangs down and the shape is fixed as it is after drying. For this reason, the outer surface side (= the side without the partition protruding from the opening height of the concave portion) is molded by sucking with a mold (soaking mold) so that such a problem does not occur.

The partition wall described above needs to be able to hold a relatively large weight fruit accommodated in each adjacent recess without being damaged during accommodation and transportation. That is, the inner wall of the recess can be bent so as not to damage relatively heavy fruits, and local protruding deformation (when a force from relatively heavy fruits is applied) It is necessary that the deformation does not cause deformations such as protruding lines, and therefore does not compress and damage the fruits.
An object of the present invention is to provide a pulp mold product that has flexibility capable of meeting the above-described requirements and does not cause local protruding deformation when bent.

Configuration 1 is a pulp mold product in which a plurality of recesses 20 for containing fruits are disposed in a tray 10 (10a / 10b / 10c / 10d) having a substantially rectangular shape in a top view, Upper support walls 27 projecting upward from the opening height H of the recesses are provided from the recess inner walls 21 at the adjacent side portions of the at least one set of recesses adjacent to each other in the recesses 20. The walls 27 and 27 are connected to each other at the upper edge portion 270 to form a peak portion in the shape of a partition wall. At least one end of the partition-shaped peak portion has an opening height of the recess 20. The relative low portion 26 lower than the opening height H of the recess 20 is curved so as to surround the flange through the flange 261 having the same height as the height H, and the peak portion is bent by the pressure from the contents in the recess. Ru conducive possible der, and wherein the pulp Mall Since a molded article, between the upper support wall 27 adjacent recess formed it can be prevented from contacting the portion upper half of the fruits can be reliably prevented from being damaged fruits. Further, the upper support walls 27, 27 of the adjacent recesses are connected to each other at the upper edge portions 270, 270, and slit-like through holes are formed between the upper edge portions 270-270. Therefore, even when a pressing force is applied to the upper edge portion 270 from the fruits, the phenomenon that the upper edge portions 270 to 270 enter (turn around) into the through hole does not occur. Therefore, as a result of the depression of the upper edge portions 270 to 270 so as to enter (turn around) into the through-hole, the thickness of the portion does not increase and local protruding deformation does not occur. There is no problem of pushing back and damaging the fruits.

Configuration 2 is that in Configuration 1, the plurality of recesses 20 are six recesses arranged at the lattice point positions in 2 rows and 3 columns (the center of each recess), and the row direction ( Two concave portions adjacent to each other in the left-right direction in FIG. 1 are connected to each other via the upper support wall 27 and the horizontal connecting portion 271 to form a partition-like peak portion, and the row direction (up-down direction in FIG. 1). ) Between two adjacent recesses by a horizontal overhanging portion 211 formed at the opening height H of the recess so that the tray 10a can be folded in the horizontal overhanging portion 211. A line 212 is formed (on the back side in FIG. 1), and the ridge that is connected to the partition-shaped peak and has a height equal to the opening height H of the recess 20 is an upper support wall that forms the peak. Komu enclose each root portion respectively contiguous to both ends in a root portion 261 which are provided and each root portion 271 Wherein each relative bottom is lower-Ku formed opening height H of the recess 20 is a groove 26 connecting the both concave portions 20 so as to bypass the crests of the respective pulp molded article, characterized in that the Therefore, the same effects as those of Configuration 1 can be obtained for a pulp molded product having six recesses 20. In addition, by folding the mountain, the size of the tray in the short side direction can be reduced, so that it can be stored in a small box, and in the short side direction, even if there is no upper support wall, mutual contact of the upper half of the fruit is prevented. This is effective in preventing damage.

Configuration 7 is the configuration 1, wherein the plurality of recesses 20 are three recesses arranged at the vertex positions of the isosceles triangle (centers of the recesses), and the positions of both ends of the isosceles in the recesses 20. Two concave portions (upper left and middle concave portions, upper right and middle concave portions in FIG. 12) are connected via the upper support wall 27 and the horizontal connecting portion 271 to form a partition-like peak portion. and it is formed with a central recessed portion 291 and having a steep slope at the same depth as the recess 20 between the two recesses in the positional relationship between the base ends (concave upper left and upper right in FIG. 12), the recess contiguous to the opening one of the relative bottom low Ku formed than the height H is a site that includes a stepped portion 2911 of the upper edge of the inclined surface of the central recessed portion 291 and the partition wall-like ridges of the recesses 20 wherein the opening height H equal to the height of 20 as incorporated enclosed by one of the relative bottom One foot part made is a flat portion extending from the foot of the mountain portion to the step portion 2911, while the relative bottom opening than the height H is low Ku formed of the recess 20 is equilateral said isosceles triangle A portion including a stepped portion 2921 on the upper edge of the slope of the shoulder depression 292 provided at both shoulders on the same side between the outside and the tray edge so as to have the same depth as the recess 20 and a steep slope. And the other brim that is connected to the partition-like ridge and is surrounded by the other relative bottom at a height equivalent to the opening height H of the recess 20 is from the ridge of the ridge. Since it is a pulp molded product characterized by being a flat portion reaching the stepped portion 2921, the same effect as in Configuration 1 can be obtained for a pulp molded product having three recesses 20. In addition, since the bottom wall of the central depression 291 is supported on the drying belt together with the bottom wall of the recess 20 when dried (when the molded product is undried and in a soft state), the supported area increases and the And shape distortion after drying can be prevented. Further, among the steep slopes of the central depression 291, slopes 29101 and 29101 in a direction connecting the tray edge 101 and the middle recess 20 try to crush the distance between the tray edge 101 and the middle recess 20. The slopes 2910 and 29102 in the direction connecting the recesses 20 and 20 at both ends act against the force to crush the distance between the recesses 20 and 20 at both ends. Therefore, it is possible to increase the force for holding the outer shape (frame shape) of the pulp molded product. That is, the strength can be increased.

The configuration 5 is the configuration 1, wherein the plurality of recesses 20 are four recesses disposed at each vertex position of the parallelogram (the center of each recess), and the farthest position among them. A pair of recesses except for a pair of two recesses (a set of upper left and lower right recesses in FIG. 8) are connected via the upper support wall 27 and the horizontal connecting portion 271 so as to form a partition wall. the ridges form a, and (in FIG. 8, upper left and upper right and lower left, upper right and lower left and lower right) three positional relationship adjacent horizontal communication which is respectively formed between two at a time three sets in the recess portions are provided continuously in star connection (Y connection) shape of the three-phase alternating current which forms the opening angle of the mutually substantially 120 ° (substantially regular intervals of opening angle), the recess 20 continuous with the mountain portion of the partition wall shape opening height H and one foot portion of the same height are root portion 261 of the upper support wall 271 that forms the ridges of the and the該根source of Becomes one of the relative bottom opening than the height H is low Ku formed of the recess 20 so as to go surrounds the該根source unit is a groove 26 connecting the both concave portions 20 so as to bypass the crests of the said recess other relative bottom opening than the height H is low Ku formation 20 and steep at the same depth as the recesses 20 at both pairs corners between the shorter sides outside and tray edge of the parallelogram It is a part including the slope of the diagonally recessed portion 293 provided so as to have a slope , and is connected to the partition-like peak portion and is surrounded by the other relative bottom portion at a height equal to the opening height H of the recess 20. The other flange portion formed so as to be formed is a flat portion extending from the foot of the mountain portion to the slope, and is formed between the remaining two adjacent recesses that are not the two furthest recesses in the farthest positional relationship. The pulp mode is characterized in that both ends of the ridge are connected to another ridge. Since it is a molded product, the same effects as those of Configuration 1 can be obtained for a pulp molded product having four recesses 20. In addition, since the horizontal connecting portions formed between three sets of two recesses in two adjacent positional relationships are connected in a star connection shape, the fruits in the three recesses are mutually connected. The effect of preventing the interference of each of the star-connected wires acts against the force of crushing in the direction of the side, so that the outer shape (frame) of the pulp molded product Shape) can be increased. That is, the strength can be increased.
Configuration 6 is a pulp mold molded product in which through hole 272 is formed in a central portion corresponding to a neutral point position in the star connection in which horizontal connection portions 271 are connected to each other in Configuration 5 Therefore, the force to crush in the direction of each side of the star connection can be released by the through hole 272.

In the configuration 3, the plurality of recesses 20 in the configuration 1 are five recesses arranged at the vertex positions and the center positions of the rectangle (centers of the recesses), in which the rectangular length Two recesses except for a set of two recesses in a positional relationship at both ends (upper left and upper right recess sets and lower left and lower right recess sets in FIG. 4) are the upper support wall 27. And three recesses (two in the form of a partition-like crest that are connected via the horizontal connecting portion 271 and consisting of two at the short side of the rectangle and one at the center) (see FIG. 4, the horizontal connecting portions formed between three sets of recesses each consisting of three recesses in the upper left, lower left and center, and three recesses in the center, upper right and lower right) It is provided continuously to a three-phase alternating current of a star connection form (Y connection) forming an opening angle of approximately 120 ° (opening angle approximately equal intervals), the partition wall-like mountain As one of the foot portion of the opening height H equal to the height of succession the recess 20 Komu surrounds the該根source portion contiguous and and the該根source portion a root portion 261 of the upper support wall 271 that forms the crests of the in one of the relative bottom opening than the height H is low Ku curved in the concave portion is a groove 26 which connects the two recesses so as to bypass the crests of the low Ku than the opening height H of the recess 20 The other formed relative bottom portion is a central depression 294 provided so as to have a steep slope having the same depth as that of the recess 20 between each of the two recesses in a positional relationship between both ends of the long side of the rectangle. It is a portion including a step portion 2941 at the upper edge of the slope, and is formed so as to be connected to the partition-like peak portion and to be surrounded by the other relative bottom portion at a height equal to the opening height H of the concave portion 20 . The other heel extends from the mountain ridge to the corresponding step 2941 Since it is a pulp mold product characterized by being a flat portion, the same effects as those of Configuration 1 can be obtained for a pulp mold product having five concave portions 20. In addition, since the horizontal connecting portions formed between three sets of two recesses in two adjacent positional relationships are connected in a star connection shape, the fruits in the three recesses are mutually connected. In addition to enhancing the effect of preventing interference, the sides of the star connection act against the force of crushing in the direction of the sides. ) Can be increased. That is, the strength can be increased.
Configuration 4 is a pulp molded product in which through hole 272 is formed in a central portion corresponding to a neutral point position in the star connection in which horizontal connection portions 271 are connected to each other in Configuration 3 Therefore, the force to crush in the direction of each side of the star connection can be released by the through hole 272.

[A] Specific example of Configuration 2 (when there are six recesses 20):
1 to 3 show a pulp mold product in which a total of six recesses 20 for accommodating fruits (eg, melon) are arranged in two rows of three. That is, the molded product is arranged such that the center position of the concave portion 20 is the grid point position of 2 rows and 3 columns. FIG. 1 is a top view. Moreover, (a)-(d) shown in FIGS. 2-3 is sectional drawing of A view-D view in FIG. 1, respectively.

  The size of the tray 10a is a size that substantially matches the shape in the cross section of a shipping box (not shown) in which the illustrated pulp mold product is set. As a method for producing a pulp molded product, as described above, a well-known pulp is used, except that the side without the upper support wall 27 protruding from the opening of the recess is sucked and molded with a mold (soaking mold). Since a method for manufacturing a molded product can be employed, description thereof is omitted.

  Each recess 20 has a recess inner wall (here, a recess inner wall in the narrow sense = side wall, hereinafter the same) 21, a bottom 23, and a groove 25 (25 p, 25 b), and a row direction (left-right direction in FIG. 1). In the portion adjacent to the upper support wall 27, the upper support wall 27 is continuously provided upward from the opening height H of the recess. The upper support wall 27 is further formed with a horizontal continuous portion 271 continuously from the upper edge portion 270 in the horizontal direction, and the horizontal support portion 271 passes through the upper support wall 27 of the concave portion 20 adjacent thereto. It is continuous. Thus, since each upper support wall 27 continuously provided from the opening part of the adjacent recessed parts 20 and 20 is continued in the horizontal continuous part 271 of the top | zenith part, with respect to the force added from the fruit in both the recessed parts 20 Thus, it can be pushed back and supported while being bent substantially evenly. Further, the upper support walls 27 and 27 of the adjacent recesses are connected to each other at the upper edge portions 270 and 270 via the horizontal connecting portion 271, and are slit-shaped between the upper edge portions 270 to 270. Since the through hole is not formed, even when a pressing force is applied to the upper edge portion 270 from the fruits, a phenomenon occurs that the space between the upper edge portions 270 to 270 falls into the through hole (turns around). Absent. Therefore, as a result of the depression between the upper edge portions 270 to 270 so as to enter (turn around) into the through-hole, the thickness of the portion does not increase and the local protruding deformation does not occur. There is no problem of pushing back and damaging the fruits. In addition, when a slit-like through hole is formed between the upper edge portions 270 to 270, the phenomenon that the upper edge portions 270 to 270 are recessed so as to enter (turn around) the through holes is the upper support wall 27. In the case where the side having no surface is sucked and molded with a mold (soaking mold) and transferred as it is to the drying belt and dried, the inside of the recess 20 is thick and the upper support wall 27 is thinly formed. This phenomenon is unavoidable.

The concave inner wall 21 has a curved surface shape that substantially matches the outer shape of the lower half of the melon, which is the fruit to be accommodated (side without wrinkles), and its lower end is flattened through the concave inner step 24. A continuous bottom 23 is provided. Note that the indented step 24 may be omitted. In other words, the lower end of the recess inner wall 21 may be continuously connected to the bottom 23 without a step.
In the case where the recess inner step portion 24 is provided, the force from the fruits is received in a relatively small area, and thus the force received is increased. For this reason, the effect | action which prevents rotation of fruits increases, As a result, the effect which prevents that fruits are damaged by rotation increases. In the case where the recess inner step portion 24 is provided, the step is a virtual extension surface of the recess inner wall 21 (a virtual surface extending from the recess inner step portion 24 toward the bottom 23; from the recess inner step portion 24 in FIG. 2B). The extent to which the center of the bottom part 23 reaches the center of the bottom part 23) is good. In other words, the height of the extent that the bottom of the fruit to be accommodated contacts the center of the bottom 23 and is supported by the center is good. When the level difference is set, the fruits are received at the center of the concave inner wall 21 and the bottom 23, so that the above-mentioned rotation preventing action can be obtained and the force from the fruits is concentrated only on the concave inner wall 21. The effect which can prevent the damage of the fruit resulting from this is also acquired.
On the other hand, when the recess inner step portion 24 is not provided, the force from the fruits is received by the recess inner wall 21 having a relatively large area, so that the force applied per unit area is reduced, resulting in force concentration. It can prevent damage to the fruit surface.

  Four grooves 25 are provided at equal intervals (90 ° intervals) in the circumferential direction of the recess 20. That is, the two groove portions 25p are provided in parallel with the long side direction of the tray 10a in the top view (left and right direction in FIG. 1), and the remaining two groove portions 25v are orthogonal to each other (up and down direction in FIG. 1). Is provided. Thus, since the four groove parts 25 are provided and the recessed part inner wall 21 is divided | segmented by the circumferential direction by this, the force per unit area which the recessed part inner wall 21 surface supports the melon which is the fruit of accommodation object It becomes larger and can prevent damage caused by rotation or rotation during transportation. Further, in the illustrated example, the groove 25 is gradually narrowed toward the bottom 23, so that the degree to which the recess inner wall 21 becomes narrower downward is reduced. For this reason, the force with which the concave inner wall 21 supports the melon does not vary greatly in the height direction (depth direction) of the concave inner wall 21, and the melon can be received with a substantially uniform force. That is, the damage prevention effect is further enhanced. In addition, the simple structure which makes the groove part 25 the same width | variety without making it gradually narrow toward the direction of the bottom part 23 is also possible.

  Further, in the groove portion 25v in the direction perpendicular to the long side direction of the tray 10a, a cut line 212 (a broken line that is on the back side of FIG. 1 and bisects the tray 10a vertically, as shown in FIGS. 3C and 3D). The lower side of the groove 25vv on the side far from the boundary (see the vicinity of the boundary) = the upper side and the lower side of the tray 10a (the lower side of the center of the recess 20) 25vvv extends along the cut line 212. In this state, the lower surface of the portion 25vvv of each recess 20 is formed at an inclination angle so as to form the same plane. In other words, in FIG. 3, when 25c of (c) and 25v of (d) close to 25v of (c) are bent so as to be aligned, 25vvv of (c) and 25vvv of (d) are horizontal planes. The inclination angle is For this reason, even when it is bent as described above, the above-described lower surface (the lower surface of 25 vvv of each recess 20) can be placed on the floor surface. Therefore, it can be accommodated in a relatively narrow transport box by folding.

  Moreover, as a result of providing the groove part 25 as mentioned above, the bottom part 23 provided in a row at the lower end of the four groove parts has a substantially T shape in a top view. Here, the T-shaped top side corresponds to the groove 25p extending in the left-right direction (long-side direction) in FIG. Moreover, the T-shaped lower side corresponds to a groove part (a groove part that is not 25 vv) closer to the aforementioned cut line 212 in the groove part 25 v extending in the vertical direction (short side direction) in FIG. 1. In this way, since the flat bottom 23 of each recess 20 has a T-shape, the tray 10a is stably supported on the floor surface by the bottom 23 when not bent as described above. In other words, the tray 10a is stably supported on the floor surface even after being taken out from the relatively narrow shipping box.

  Further, the opening height H of the recess 20 is the same between the recesses 20 and 20 adjacent in the row direction (vertical direction in FIG. 1), that is, between the recesses 20 and 20 adjacent to each other across the cut line 212. A horizontal overhanging portion 211 that is horizontally provided at a height is provided, and the horizontal overhanging portion 211 keeps the distance between the two recesses 20 and 20 relatively wide. For this reason, even if there is no upper support wall that separates the upper half side of the melon in both recesses 20 between the recesses 20 and 20 that are adjacent to each other with the cut line 212 interposed therebetween, it is also possible to fold the mountain at the part of the cut line 212. Even without this, contact and damage to the upper half of the melon can be prevented.

In the pulp mold product of FIG. 1, the recesses 20 and 20 adjacent to each other with the upper support wall 27 sandwiched between the base portions of both ends of the upper support wall 27 (vertical end portions in FIG. 1). A groove 26 is formed by cutting out the opening edge 210, thereby increasing the strength of the root portion 261 of the upper support wall 27. Further, at the four corners of the tray 10a, there are formed lower portions 260 formed so as to cut out the opening edge 210 of the recess 20, and the strength of the periphery is similarly increased.
In addition, the hatched portion indicated by reference numeral 28 in the figure is a stopper formed on the back side, and when the pulp molded product is stacked in another stage, it is easy to peel off with a mechanical device or the like. It is a part for ensuring a gap between pulp molded products.

[B] Specific example of configuration 7 (when there are three recesses 20):
FIGS. 12 to 15 show the case where the center position of the recess 20 for accommodating fruits (e.g. melon) is arranged to be the vertex positions of the isosceles triangle, that is, the number of the recesses 20 is three. The pulp molded product in a certain case is shown. 12 is a top view, and FIG. 13 is a cross-sectional view taken along line AA in FIG. Moreover, (b)-(e) shown in FIGS. 14-15 is sectional drawing of the B view-E view in FIG. 12, respectively.
Here, the configuration different from the above-described example in the case of six recesses will be mainly described, and the same configuration is denoted by the same reference numeral, and the description will be simplified or omitted.

  In the tray 10 b of FIG. 12, two concave portions that are in a positional relationship between both ends of an isosceles triangle are connected via an upper support wall 27 and a horizontal connecting portion 271. A central depression 291 having the same depth and a steep slope as the depression 20 is formed between the two depressions in the positional relationship between both ends of the base of the isosceles triangle. On the upper edge of the slope 2910 near the intersection of the virtual extension lines of the two horizontal connecting portions 271 and 271 formed between the two concave portions, the opening height of the concave portion 20 is provided. A step portion 2911 having a predetermined width lower than H is formed. Further, on both shoulders between the equilateral sides of the isosceles triangle and the tray edge 101, both shoulder depressions 292 having the same depth as the recess 20 and having steep slopes are formed. A stepped portion 2921 having a predetermined width lower than the opening height H of the recessed portion 20 is formed at the upper edge of the inclined surface 2920 adjacent to the recessed portion 20, which is the inclined surface of the shoulder recess portion 292.

Since the bottom wall of the central depression 291 and the bottom wall of both shoulder depressions 292 are supported on the drying belt together with the bottom wall of the recess 20 when dried (when the molded product is in a dry and soft state), The supported area can be increased to prevent settling, and shape distortion after drying can also be prevented.
Of the steep slopes of the central depression 291, the slopes 29101, 29101 in the direction connecting the tray edge 101 and the middle recess 20 push in the direction of narrowing the distance between the tray edge 101 and the middle recess 20. Acts so as to resist the force, and the slopes 2910 and 29102 in the direction connecting the recesses 20 and 20 at both ends act to resist the pressing force in the direction of narrowing the interval between the recesses 20 and 20 at both ends. For this reason, it is possible to increase the force for retaining the outer shape (frame shape) of the pulp molded product. That is, the strength can be increased. This effect can be further enhanced by the stepped portion 2911.
In addition, the steep slopes of both shoulder depressions 292 act against the pushing force in the direction of narrowing the gap between the tray edge 101 and the recesses in the vicinity of both shoulder depressions 292. The force which retains the outer shape (frame shape) of the molded product can be increased. That is, the strength can be increased. Further, this effect can be further enhanced by the stepped portion 2921.

[C] Specific examples of configurations 5 to 6 (when there are four recesses 20):
FIGS. 8 to 11 show the case where the center position of the recess 20 for accommodating fruits (e.g. melon) is arranged at the apex positions of the parallelogram, that is, the number of the recesses 20 is four. The pulp molded product in a certain case is shown. 8 is a top view, and FIG. 9 is a cross-sectional view taken along line AA in FIG. Moreover, (b)-(e) shown in FIGS. 10-11 is sectional drawing of the B view-E view in FIG. 8, respectively, (f) shows the shape of a star connection (Y connection). It is explanatory drawing.
Here, a description will be mainly given of a configuration different from the above-described example in the case where the number of recesses is 6 or 3, and the same configuration is denoted by the same reference numeral, and the description is simplified or omitted.

In the tray 10c of FIG. 8, two concave portions except for a pair of two concave portions that are farthest among the vertex positions of the parallelogram form the upper support wall 27 and the horizontal connecting portion 271. In addition, the horizontal connecting portions formed between three sets of recesses in pairs in three adjacent positional relations are three-phase forming an opening angle of approximately 120 ° with respect to each other. An AC star connection (Y connection) shape is connected. The three-phase AC star connection shape means a shape as shown in FIG. Further, a through hole 272 is formed at a central portion corresponding to the neutral point position (connection position) in the star connection. Further, the horizontal connecting portion 2710 formed between the remaining two adjacent concave portions which are not the two concave portions in the farthest positional relationship is shared as one side in the two sets of star connection shapes. .
In addition, diagonal depressions 293 having the same depth as the recesses 20 and having steep slopes are formed at both diagonal corners between the short side outside of the parallelogram and the tray edge 101. .

Since the bottom wall of the diagonally recessed portion 293 is supported on the drying belt together with the bottom wall of the concave portion 20 when drying (when the molded product is undried and in a soft state), the supported area increases and the settling is reduced. It is possible to prevent the shape distortion after drying.
In addition, each steep slope of the diagonal depression 293 acts against a force pushing in the direction of narrowing the interval between the tray edge 101 and the concave portion in the vicinity of the diagonal depression 293, so that the tray The force for holding the outer shape (frame shape) of 10c can be increased.
In addition, the effect of preventing mutual interference between the fruits in the three recesses around the star connection can be enhanced by the horizontal connection part continuously provided in the star connection shape, and each side of the star connection is Since it acts so as to resist the pushing force in the direction of narrowing the side, the force for holding the outer shape (frame shape) of the tray 10c can be increased. Also, a horizontal connecting portion 2710 formed between the remaining two adjacent concave portions that are not the two concave portions in the farthest positional relationship is shared as one side of two sets of star connection shapes. Since it acts so as to resist the force of crushing the side in the direction of the shared side, the force for holding the outer shape (frame shape) of the tray 10c can be further increased.
In addition, since the through hole 272 is formed in the central portion of the star connection, the force to crush in the direction of each side of the star connection can be released by the through hole 272.

[D] Specific examples of configurations 3 to 4 (when there are five recesses 20):
4 to 7 show the case where the center position of the recess 20 for accommodating fruits (eg, melon) is arranged such that the four vertex positions and the center position of the rectangle are located, that is, the recess 20. Shows a pulp mold product in the case of 5 pieces. 4 is a top view, and (a) to (f) shown in FIGS. 5 to 7 are cross-sectional views taken along lines A to F in FIG. 4, respectively. Moreover, FIG.7 (g) is explanatory drawing which shows the shape of a star connection (Y connection).
Here, the configuration different from the above-described example when there are 6, 3, and 4 recesses will be mainly described, the same configuration is denoted by the same reference numeral, and the description will be simplified or omitted.

  In the tray 10d of FIG. 4, a total of four sets of recesses are connected via the upper support wall 27 and the horizontal connecting portion 271 except for a set of two recesses in a positional relationship between the long sides of the rectangle. It is installed. In addition, the horizontal connecting portions formed between three sets of two concave portions each composed of two concave portions each having a positional relationship between both ends of the rectangular short side and one central position are mutually connected. Are connected in a three-phase AC star connection (Y connection) shape having an opening angle of approximately 120 °. The three-phase AC star connection shape means a shape as shown in FIG. Further, a through hole 272 is formed at a central portion corresponding to the neutral point position (connection position) in the star connection. In addition, a central recess 294 having a steep slope with the same depth as the recess 20 is formed between each of the two recesses in a positional relationship between both ends of the long side of the rectangle. A step portion 2941 lower than the opening height H of the concave portion 20 is formed on the upper edge portion of the inclined surface 2940 on the side adjacent to the concave portions at both ends of the long side of the rectangle.

Since the bottom wall of the central depression 294 is supported on the drying belt together with the bottom wall of the recess 20 when dried (when the molded product is undried and soft), the supported area increases and prevents settling. And shape distortion after drying can be prevented.
In addition, each steep slope of the central depression 294 acts against the force pushing in the direction of narrowing the gap between the tray edge 101 and the recess in the vicinity of the central depression 294. The force for holding the outer shape (frame shape) can be increased. This effect is further enhanced by a stepped portion 2941 formed at the upper edge of the inclined surface 2940 on the side adjacent to the concave portions at both ends of the long side of the rectangle, which is the inclined surface of the central depression 294.
