Description

  The present invention relates to a fruit storage tray for safely transporting relatively easily damaged fruits such as strawberries.

  Conventionally, a flat film in which a paint containing a water-absorbing resin is applied in advance to each of the openings of the concave and convex containers facing each other is bonded to the outer periphery of the opening so that the paint surface becomes the outer surface, and the upper and lower water-absorbing resins In some cases, fresh foods (contents) were sandwiched between them, and the upper and lower films on the outer periphery of the paint containing the upper and lower water-absorbing resins were bonded to the upper and lower bodies with a heat seal lacquer.

  That is, the upper and lower films that connect the content-coated water-absorbing resin paint and the outer edge bonding portion of the upper and lower concave molded containers were bonded to form a single body (for example, Patent Document 1).

  In addition, the stored item is accommodated in a vertically opposed concave container in a state of being suspended in a suspended state between the upper and lower cushioning functional flat films, and the circumscribed portion of the upper and lower containers and the stored item are supported by the upper and lower inclined films. (For example, patent document 2).

  In addition, an elastic foam material sheet such as foamed polyethylene with a fruit storage recess formed on top of a plastic tray with a plurality of recesses for holding is proposed to store fruits such as strawberries in the storage recess. (Patent Document 3).

  All of these containers are provided with a buffer function so that the contents or the stored items can withstand vibration.

  However, since the film between the outer periphery of the paint layer containing the water-absorbing resin paint in contact with the contents and the container is a film in which the film between the container and the container is adhered in the upper and lower directions in the case of Patent Document 1, the upper and lower layers are bonded in the up-and-down vibration of the contents. The film has the effect of suppressing the lifting vibration, the contents are contained in a relatively hard paint, the lifting is suppressed by the upper and lower mutual adhesive films, and it is difficult to sufficiently release the lifting vibration energy.

  In addition, since the film is flat on both the upper and lower sides, even if the contents are stored, a gap is formed between the film and the contents (see Patent Document 1, FIG. 2). There is a problem that the shift cannot be suppressed.

  In addition, even in the case of Patent Document 2, when the stored object is raised or lowered, the other of the upper and lower inclined films is loosened, but one of the films is stretched to suppress the vibration action and it is difficult to sufficiently release the raised and lowered vibration energy. There was a problem that it was difficult to apply to vibration-resistant packaging because the surface of a fruit that was easily broken such as straw was damaged.

  In addition, when the contents are sandwiched from above and below on the flat film surface as in Patent Documents 1 and 2, if the contents are soft fruits such as strawberries, the pressure on the film surface is suppressed from the top and bottom. There is a problem that the fruit itself is crushed or a part where pressure is applied is partially crushed.

  Furthermore, the thing of the patent document 3 has the thickness of about 3 mm in the elastic foam material sheet, and since the softness | flexibility of a storage recessed part is low, when a fruit is stored in a recessed part, a clearance gap will be produced between a fruit and a sheet | seat (patent document 3, see FIG. For this reason, the fruit causes a lateral shift or the like in the recess, and the fruit surface is damaged based on the lateral shift. Furthermore, there is a hard partition made of a plastic tray between adjacent storage recesses (see Patent Document 3, FIG. 1 and FIG. 3), and since the elastic foam sheet is in close contact with the partition, There is a problem that when the fruit collides with the partition wall due to vibration such as transportation, the portion of the fruit that contacts the partition wall is damaged.

  In addition, as shown in FIG. 27, a nonwoven fabric 42 is stuck on the entire surface of the hard plastic tray 41 in which a plurality of fruit accommodation recesses 40 are formed, and only a portion corresponding to each accommodation recess 40 is nonwoven fabric. The center part of the nonwoven fabric 42 is loosened to form a recessed portion 43 in a suspended state, and a fruit is accommodated in the recessed portion 43 of the nonwoven fabric 42, but since the friction coefficient of the surface of the nonwoven fabric 42 itself is large, When a fruit whose surface is easily damaged is stored in the recess 43, there is a problem that the nonwoven fabric 42 and the fruit surface slide due to vibration during transportation, thereby damaging the fruit surface.

  Further, in such a conventional fruit storage tray, since the nonwoven fabric 42 is adhered to the partition wall 44 in a close contact state, the recess 43 is flexible but the partition wall 44 is hard and not flexible. There is a problem that when the stored fruit abuts against the partition wall 44 due to vibration or the like during transportation, the abutting portion of the fruit is damaged.

  12thly, the said thermoplastic synthetic resin thin sheet is comprised by the fruit accommodation tray in any one of the said 1st-11 characterized by 10-150 micrometers.

  Accordingly, the thermoplastic synthetic resin thin sheet is adhered to the outer surface of the longitudinal and lateral side plates, for example, and is adhered to the upper surface of the upward projections of substantially the same height provided at equal intervals in the longitudinal and lateral directions. The central part of the portion surrounded by upward projections adjacent to the vertical and horizontal adjacent thermoplastic synthetic resin thin sheets stretched on the surface is plastically deformed by heating and pressing, for example, so that the fruit receiving recess has a substantially semicircular arc shape. It is made to form approximately half the height.

  The outer side (upper edge outer surface) of the recess and the outer peripheral portion (outer peripheral surface) of the upward projection remain as the same flat surface. When a plurality of recesses are provided, the same flat surface and the recess are the same as those of the rectangular tray. A large number of vertical and horizontal are formed inside, and when fruits such as strawberries are accommodated in the recesses, and the fruit-accommodating recesses are opposed to each other, the rectangular trays face downward on the upper surface and the recesses are opposed to each other. Place fruit in a square tray facing up and down.

  Even when the recess of the thermoplastic synthetic resin thin sheet is plastically deformed in advance, the outer surface of the upper edge of the recess and the outer peripheral surface of the upward projection still remain flat, so the weight of the fruit contained in the recess Can be supported by the elasticity of the flat stretched sheets on the outer and outer periphery.

  Further, at the edge H between the outer periphery of the recess and the horizontal surface 5a extending from the outer periphery to the periphery, there is no support member on the back side, and the edge H is formed only by a plastically deformed thin sheet. Therefore, the thickness of the edge H is only the thickness of the sheet (for example, about 10 μm to 150 μm), and it is extremely thin and flexible and stretchable. Even the fruit surface will not be damaged.

  In addition, when the number of fruit receiving recesses is small, it is possible to suspend and support the fruit only with the thin thermoplastic synthetic resin sheet stretched on the tray without providing upward projections, thereby preventing damage to the fruit. A fruit storage tray can be realized.

  In addition, in a thin sheet provided with a fitting frame, the tray and the fitting frame can be accommodated and transported in a compact manner, and the tray and the fitting frame can be assembled on site to be used as a fruit accommodation tray. There is an effect. When the tray itself is transported, the tray portions are stacked only with the tray, and when the fitting frames are stacked, as shown in FIG. Therefore, when transporting the fruit storage container, the tray and the fitting frame can be overlapped and transported in a compact manner, and a thin sheet can be assembled and assembled to the tray with the fitting frame on site. It becomes possible to perform the operation | work which accommodates a fruit in a recessed part. (0074)

  A rectangular tray 1 formed by forming vertical and horizontal side plates 3, 3 'on the outer periphery of the rectangular bottom plate 2 is formed by synthetic resin, pulp mold, base paper or cardboard.

  The bottom plate 2 is provided with a plurality of upward projections 4 at equal intervals along the vertical and horizontal side plates 3 and 3 ', and the height thereof is the same as or substantially the same as the upper surface of the side plates 3 and 3'. .

  The upward protrusion 4 is formed as one body with the bottom plate 2 when the rectangular tray 1 is made of synthetic resin or pulp mold, and the upward protrusion 4 made of the base paper is bonded to the bottom plate 2 with base paper or corrugated cardboard or cut into one body. Form (FIG. 20).

  In the tray 1 thus formed, an adhesive or an adhesive material is applied to the upper and outer surfaces 3 ″ of the vertical and horizontal side plates 3 and 3 ′ and the upper surfaces of the upward projections 4, respectively. The thermoplastic synthetic resin thin sheet 5 is placed flat on the upper surface of the directional projection 4 while being pulled slightly vertically and horizontally, and the outer edge of the thin sheet 5 is placed on the upper surface of the side plates 3 and 3 ′ and the outer surface 3 ″ (or Adhering or sticking 4 'to the upper surface or outer surface 3 "), and the lower surface of the sheet 5 is attached or sticking 4' to the upper surface of the vertical and horizontal upward projections 4 '.

  A thin film of polyethylene, polypropylene, polyurethane, polystyrene or the like is used for the thermoplastic synthetic resin thin sheet 5. The thickness of the sheet 5 is 5 μ to 250 μ, preferably 10 μ to 150 μ, and the thickness varies depending on the contents. In the description of this embodiment, the sheet 5 is expressed as “sheet”, but the sheet 5 is very thin specified by the above-mentioned thickness regardless of expression of “sheet” or “film”. A thermoplastic synthetic resin thin sheet or a thermoplastic synthetic resin thin film. In this specification, the expression “sheet” is used for convenience. For example, in the case of relatively small and light fruits such as strawberries, a sheet having a thickness of 10 μm may be used, and in the case of large and heavy fruits such as pears, a sheet having a thickness of 150 μm may be used.

  5 × 7 = 35 upward projections 4 are arranged at regular intervals (about 30 mm) in the vertical and horizontal directions, and the above-mentioned square thin sheet formed by four upward projections 4, 4, 4 and 4 adjacent to or adjacent to each other in the vertical and horizontal directions 5 (FIG. 2) is pressed downward (down) by a bottom arc spherical heating tool 7 (see FIG. 2) to form 4 × 6 = 24 fruit (苺) accommodating recesses 6 vertically and horizontally by plastic deformation (FIG. 2). FIG. 3).

  However, a space t is interposed between the recess 6 and the bottom plate 2 (FIG. 3).

  When pressing (pressing) the concave portion 6 with the heating tool 7, the upper edge outer surface of the concave portion 6, that is, the planar portion extending from the outer peripheral edge of the concave portion 6 and the outer peripheral surface of the upward projection 4 are described above. The thin sheet 5 is pulled to hold one horizontal surface (flat surface) 5a, and there is no fear of causing thermoplastic deformation in the horizontal surface 5a. At the time of the thermoplastic deformation, the outer thin sheet surface of the central recess 6 and the upward projection 4 The outer peripheral thin sheet surface holds the common thin sheet flat surface 5a before the deformation.

  That is, only the central concave portion 6 is formed by plastic deformation by the heating tool 7, and the peripheral surface of the central concave portion 6 remains in a state where the horizontal surface 5 a without plastic deformation is maintained. Therefore, the sheet 5 in the central recess 6 portion is plastically deformed, so that the sheet surface is stretched as a whole, and the thickness thereof is thinner than the horizontal surface 5a without plastic deformation. Therefore, when the fruit is stored, the sheet of the concave portion 6 itself can be easily extended along the fruit surface, whereby the sheet of the concave portion 6 can be in close contact with the fruit surface and the fruit can be held more reliably.

  Fruits 8 such as strawberries are accommodated in the recesses 6 formed in this way, and the same tray 1 is crowned downward as shown in FIG. 4 to accommodate the fruits 8 in the opposite recesses 6 and 6. Can be packed and transported. At this time, when the fruit is accommodated in the central recess 6, the central recess 6 is thinner than the horizontal surface 5 a due to plastic deformation, and is close to the fruit surface because it is rich in elasticity and flexibility, and reliably surrounds the accommodated fruit. Can do. Further, since the horizontal surface 5a around the periphery of the recess 6 is not plastically deformed and remains in its original thickness (for example, 10 μm to 150 μm), the fruit accommodated by its elasticity is reliably supported in a suspended state (suspended state). Can do.

  When the accommodation fruit 8 descends due to vertical vibration during transportation, the upward recess 6 and the common flat surface 5a on the outer periphery thereof descend with the weight of the fruit as shown by the phantom line in FIG. , 5a is separated and the contained fruit 8 is sufficiently lowered.

  On the contrary, when the accommodation fruit 8 is raised by vertical vibration, the downward concave portion 6 and the common flat surface 5a on the outer periphery thereof rise by the weight of the fruit 8 as shown by phantom lines in FIG. , 5a separates and the contained fruit 8 rises sufficiently.

  Therefore, the up-and-down vibration of the accommodation fruit 8 adapts without being suppressed by the thin sheet 5 of the upward and downward recesses 6 and 6, and the risk of damage to the upper and lower surfaces of the fruit 8 is reduced.

  Further, when the stored fruit 8 moves left and right (in the directions of arrows a and a ′ in FIG. 4) due to left and right vibrations during transportation, the central recess 6 is in close contact with the lower half and upper half of the fruit 8. Therefore, the fruit 8 does not shift in the left-right direction in the concave portion 6, and the concave portion 6 and the flat surface 5 a effectively suppress left-right displacement or vibration of the fruit 8. Thereby, damage to the left and right side surfaces of the fruit 8 can be prevented.

  In FIG. 2, reference numeral 9 denotes a pressing tool for sticking 4 ′ of the thin sheet 5 on the upper surface of the upward projection 4.

  The central recess 6 of the thermoplastic synthetic resin thin sheet 5 can be molded by the heating tool 7 as described above, but before the thin sheet 5 is attached to the tray 1, vacuum molding, vacuum compressed air It can also be formed by molding. As shown in FIG. 5A, the vacuum molding is performed by heating the thermoplastic synthetic resin thin sheet 5 in advance with a heater 10 (FIG. 5A), and then, as shown in FIG. A thin sheet 5 is disposed above the mold 11 and vacuum suction (arrow b) is performed from below the mold 11 to form a substantially hemispherical central recess 6 by plastic deformation.

  Further, in the vacuum / compression molding, as shown in FIG. 6, the thermoplastic synthetic resin thin sheet 5 is preliminarily heated by the heater 10 (FIG. 6 (a)), and then the thin film is formed as shown in FIG. 6 (b). The sheet 5 is inserted into the vacuum chamber 12 and vacuum suction (arrow b) is performed from below the mold 11 while being compressed from above (arrow c), thereby forming a substantially hemispherical central recess 6 by plastic deformation. In any of the above molding methods, the flat surface 5a without plastic deformation remains on the outer surface of the recess 6. When such a molding method is adopted, the thermoplastic resin in which the central recess 6 as shown in FIG. 1 (FIGS. 8 and 25) is molded although the thin sheet 5 is an extremely thin sheet of 10 μm to 150 μm. The synthetic resin thin sheet 5 can be formed in advance before mounting on the tray 1.

  Then, in a state where the thin sheet having the central recess 6 formed in advance is slightly stretched vertically and horizontally (in the directions of the arrows d1 to d4) (see FIG. 25), the upper surface and the outside of the side plates 3 and 3 ′ of the tray 1 A fruit storage tray as shown in FIG. 1 can be formed by adhering 4 ′ to the side surface 3 ″ (or the upper surface or the outer surface 3 ″) and the upper surface of the upward projection 4 with an adhesive.

  Since the thickness of the thin sheet 5 is thin, and in particular, the thickness of the concave portion 6 is thinner than the flat surface 5a, after the entire shape is trimmed to a square after molding, the concave portion 6 and the concave portion 6 and as shown in FIGS. In some cases, the surface of the sheet 5 may not be maintained and may become an indefinite shape, but the thin sheet 5 has elasticity and flexibility, so the thin sheet 5 is slightly stretched vertically and horizontally. When the fruit is accommodated in the recess 6 after being attached to the tray 1 in a state, the surface of the sheet 5 is expanded to form a horizontal surface 5a, and the sheet in the recess 6 is expanded as shown in FIG. 7B. It adheres to the side surface of the fruit 8 and can reliably hold the cocoon.

FIG. 8 to FIG. 10 show a second embodiment of the fruit storage tray according to the present invention.
In these drawings, the same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. In this second embodiment, the corners of the four sides of the upper surface of the upward projection 4 are rounded into an arc shape, and the upper end portion of the upward projection 4 is a round projection (round projection) 4a. is there. If comprised in this way, in the state which stuck the thermoplastic synthetic resin thin sheet 5 to the upper surface of the side plates 3 and 3 'of the said square tray 1, and the upward protrusion 4, and accommodated the fruit in the center recessed part 6, it is an arrow P direction. When a (downward) force acts strongly (see FIG. 10), the sheet 5 around the upper surface of the round protrusion 4 a is not damaged at the corner of the upper end of the upward protrusion 4. As shown in FIG. 11 (a), the round protrusion 4a may be formed with only a corner 4a 'in an arc shape at the upper end of the upward protrusion 4, leaving a flat surface, as shown in FIG. ), The entire upper end may be formed in an arc shape.

  FIGS. 12 to 14 show a third embodiment of the fruit storage tray according to the present invention. In these drawings, the same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. In the fruit storage tray of FIG. 12, 6 ′ is a central recess of the thermoplastic synthetic resin thin sheet 5, and its shape is a cocoon shape. Specifically, when viewed from the plane of the central recess 6 ′ (see FIG. 12), it has a bowl shape composed of a wide portion 6a ′ and a narrow portion 6b ′, and when viewed from the side. (Refer to FIG. 13) It has a deep portion 6c ′ and a shallow portion 6d ′, and the two side-by-side rectangular trays 1 are vertically aligned so that the side surface has a substantially bowl shape (FIG. 14). reference).

  According to the third embodiment, when the ridge is accommodated in the concave portion 6 ′ in accordance with the shape of the central concave portion 6 ′, the adhesion between the sheet 5 and the heel increases, so that the concave portion 6 ′ It can be held more reliably. Therefore, the same effects as those of the first embodiment can be obtained, and when the storage basket 8 moves left and right due to left and right vibration during transportation, the central recess 6 ′ is surely provided in the lower half and the upper half of the basket 8. Since the flange 8 'does not shift in the left-right direction in the recess 6', the recess 6 'suppresses the horizontal displacement of the flange 8, and the flat surface 5a is Mainly enough to support vertical vibrations without damaging the bag, it is possible to effectively prevent damage to the bag 8 during transportation.

  15 and 16 show a fourth embodiment of the fruit storage tray according to the present invention. In these drawings, the same reference numerals are given to the same parts and corresponding parts as those in the first embodiment, and the explanation is given. Omitted. In the figure, the difference from each of the above embodiments is that the number of central recesses 6 of the thermoplastic synthetic resin thin sheet 5 is four and that the upward projections 4 do not exist on the tray 1 bottom plate 2.

  In FIG. 15, the tray 1 is composed of a bottom plate 2 and side plates 3, 3 ′ that are the same as those in the first embodiment, but the size corresponds to the four recesses 6. There are no upward projections in the center corresponding to the four recesses. In this embodiment, the periphery of the thin sheet 5 is formed by sticking 4 ′ (see FIG. 16) to the upper ends of the side plates 3, 3 ′ of the tray 1. Thus, when there are few fruit accommodation recessed parts 6 (for example, 4, 3, 2, 1 etc.), even if there is no upward protrusion like this 4th Embodiment, The fruit can be supported only by the tension of the horizontal surface 5a, and the same effect as in the first to third embodiments can be obtained. Note that the number of the recesses 6 may be three, or two or one. You may make it wrap a fruit by making the recessed part 6 of the said tray 1 oppose.

  In any of the first to fourth embodiments, there is no support member on the back side of the edge H between the outer periphery of the central recess 6 (6 ′) and the horizontal surface 5a extending from the outer periphery to the periphery. Since the edge H is formed only by the plastically deformed thin sheet 5 (FIGS. 15 and 16), the thickness of the edge H is only the thickness of the sheet 5 (for example, about 10 μ to 150 μ). And the surface of the fruit 8 will not be damaged even if the edge 8 is hit by the fruit 8 such as strawberries (the edge H is not shown in the figure). 9, FIG. 10, FIG. 12 to FIG. 14, FIG. 17, FIG. 18, FIG.

  Further, since the thin sheet 5 is attached to the upper surface of the tray 1 in a stretched state, the fruit in the recess 6 is reliably suspended and supported by the horizontal surface 5a, and the vertical vibration is not hindered and suspended in the air. It can be safely transported without colliding anywhere during transportation.

  17 and 18 show a fifth embodiment of the fruit storage tray of the present invention. A hard plastic fitting is fitted to the periphery of the thin thermoplastic rigid resin sheet 5 of the fourth embodiment shown in FIG. An alignment frame 20 is provided. The fitting frame 20 has a rectangular frame shape similar to the rectangular upper end shape of the tray 1, and as shown in FIG. 17, a downward fitting groove 20a is formed over the entire circumference, and the downward direction The fitting groove 20 a can be fitted to the upper edge 1 ′ of the tray 1. That is, a fitting frame 20 having a downward fitting groove 20a is provided at the periphery of the thermoplastic synthetic resin thin sheet 5, and the sheet 5 is supported in a flat stretched state in the frame 20, and the periphery of the sheet 5 is The thin sheet 5 is supported on the upper surface of the tray 1 by fitting and fitting the fitting frame 20 to the side plate of the tray 1 instead of adhering directly to the side plate of the tray 1 (FIG. 18A). ) (B)).

  That is, the thin sheet 5 is stretched on the inner side of the fitting frame 20 by sticking the outer peripheral edge of the thermoplastic synthetic resin thin sheet 5 to the inner plane portion of the fitting frame 20. Then, the thin sheet 5 is flatly supported on the tray 1 by fitting the fitting frame 20 on which the thin sheet 5 is stretched into the upper end 1 ′ of the tray 1.

  When configured in this way, the same effects as in the fourth embodiment can be obtained, and when the tray 1 itself is transported, the tray portions are stacked only by the tray 1 and the fitting frame 20 is stacked as shown in FIG. It is possible to superimpose the concave and convex portions 6 in a state where they are crushed into an indefinite shape. Therefore, when transporting the fruit container, the tray 1 and the fitting frame 20 can be stacked in a small size and transported in a compact manner, and the thin sheet 5 can be fitted to the tray 1 with the fitting frame 20 on site. It becomes possible to perform the operation | work which assembles together and accommodates a fruit in the recessed part 6. FIG.

  20 to 22 show a sixth embodiment of the present invention. In addition, the same code | symbol is attached | subjected about the part same as the said 1st Embodiment, or a corresponding part. In this embodiment, the rectangular tray 1 is constituted by cardboard. That is, the side plates 3 and 3 ′ are formed on the four sides of the flat rectangular corrugated cardboard, and the side plates 3 and 3 ′ on the four sides are raised with respect to the bottom plate 2 to form the rectangular tray 1 of FIG. 20.

  In order to form a plurality of upward protrusions 4, a pair of parallel straight lines L 1 and L 1 are left facing the central portion of the bottom plate 2, and a substantially “U” -shaped cut 30 is provided to face each other. Stand up in parallel. At this time, by forming the cut lines facing L1 and L2 into a waveform, three apex portions (4, 4, 4) in series in the longitudinal direction are formed on the upper edges of both cut and raised pieces 31, 31 and cut. The vertex portion is caused to function as the upward projections 4, 4, 4 so that the vertex portion becomes the highest when it is raised. Further, a downward cut line 32 is made in the central vertex 4.

  Further, a standing piece 33 is separately provided with the same cardboard, and two highest apex portions (4, 4) are formed on the upper edge of the standing piece 33 as upward projections, and a bottom corresponding to the apex portion is formed. A cut 34 is formed in the direction from the edge to the apex (4, 4). Then, in a state where the upright piece 33 is orthogonal to the cut and raised pieces 31 and 31, the cut lines 34 and 34 and the cut lines 32 and 32 of the raised pieces 31 and 31 are combined to form the upright piece 33. The upright pieces 33 are inserted into the cut and raised pieces 31 and 31 so as to stand upright on the bottom plate 2 (see FIGS. 21 and 22). With this configuration, six upward projections 4 are formed by the cut and raised pieces 31, 31 on the bottom plate 2, and two upward projections 4 are formed by the upright pieces 33 in a direction perpendicular to the upward projections 4.

  The material of the thermoplastic synthetic resin thin sheet 5 is the same as that of the first to fifth embodiments, and the method for forming the fruit accommodating recess 6 on the sheet surface is the same as that of the above embodiment. In the form, the outer peripheral portion of the sheet 5 (four side portions of the flat sheet 5) is further bent downward and substantially perpendicular to the sheet surface, and the frame engaging bent portion 5d is formed over the entire periphery integrally with the sheet. Yes. Further, at both ends of the pair of frame engaging bent portions 5d opposed to each other in the longitudinal direction, protrusions for engaging with protrusions (engagement protrusions) 36 of an outer peripheral frame 35 (described later) in a fitted state ( Engagement portions) 5c are formed at four locations. Further, when the thermoplastic synthetic resin thin sheet 5 is coated on the outer peripheral frame 35, the depth of the concave portion 6 is an upper position from the lower edge position of the outer peripheral frame 35, that is, the vertical width of the outer peripheral frame 35. It is comprised so that it may be located to about / 2 (refer FIG. 22).

  This thin thermoplastic synthetic resin sheet 5 can be formed by the vacuum forming method shown in FIG. That is, a plurality of fruit receiving recesses 50a and protrusions 50b corresponding to the protrusions 5c are formed at the four corners, and a substantially rectangular parallelepiped mold 50 having a plurality of suction through holes 50c (see FIG. )) Is placed horizontally on the net-like plate 51, and is coated with the thermoplastic synthetic resin thin sheet 5 softened by heating on the mold 50 (see (a) in the figure). By performing vacuum suction (arrow d) through the suction through hole 50c, the thermoplastic synthetic resin thin sheet 5 having the fruit accommodating recess 6, the frame engaging bent portion 5d and the protrusion 5c shown in FIG. 20 is formed. be able to.

  Reference numeral 35 denotes an outer peripheral frame of the thermoplastic synthetic resin thin sheet 5, and a pair of long corrugated cardboard pieces 35a and 35a having a constant width and a pair of short corrugated cardboard pieces 35b and 35b having the same width are connected in an upright state. Formed on top. This outer peripheral frame 35 has a rectangular shape as a whole by providing vertical folding lines 37, 37, 37 at three locations on one long cardboard, bending the folding lines at right angles, and adhering both ends to each other. It can comprise by forming in.

  The cardboard pieces 35a, 35a of the outer peripheral frame 35 are integrally formed with protrusions 36 for preventing the sheet 5 from slipping, and when the outer peripheral frame 35 is formed, the protruding pieces 36 are formed in the longitudinal direction. The cardboard pieces 35a, 35a in the direction are configured to protrude in the outer direction in parallel with the cardboard pieces 35a, 35a at both upper ends.

  The size of the outer peripheral frame 35 is substantially similar to that of the tray 1, that is, substantially similar to the outer peripheral shape of the tray 1 so as to be accommodated in the rectangular tray 1. The lengths of the cardboard pieces 35a and 35a are slightly shorter than the inner length of the side in the longitudinal direction of the tray 1 including the projecting piece 36, and the lengths of the cardboard sides 35b and 35b are as described above. When the outer peripheral frame 35 is accommodated in the tray 1, the side 35 a comes into contact with the inner surface in the longitudinal direction of the tray 1 and the side 35 b is shorter than the inner length of the short side of the tray 1. Is configured to be located close to the inner surface of the short side of the tray.

  Concave folding lines 35c and 35c are provided in the central portions of the corrugated pieces 35a and 35a in the longitudinal direction of the outer peripheral frame 35. As a result, the corrugated pieces 35a and 35a of the outer peripheral frame 35 are shown in FIG. As shown in FIG. 5, the short cardboard pieces 35b and 35b are folded close to each other by bending them inwardly around the folding lines 35c and 35c and further arranging the bent portions 35c and 35c alternately. Can be done. In addition, this folding can be performed with the thermoplastic synthetic resin thin sheet 5 attached to the outer peripheral frame 35 (see FIG. 24).

  Since the sixth embodiment is configured as described above, first, the cut and raised pieces 31 and 31 of the tray 1 are erected at right angles to the bottom plate 2, and the raised piece 33 is orthogonal to the cut and raised pieces 31 and 31. In this state, by inserting the cut lines 34 and 34 into the cut lines 32 and 32, the upright piece 33 is fixed on the bottom plate 2 in a state orthogonal to the cut and raised pieces 31 and 31 (FIGS. 21 and 22). reference).

  On the other hand, the outer peripheral frame 35 is spread in a square shape, and the outer peripheral frame 35 is covered with the thermoplastic synthetic resin thin sheet 5, and the sheet surface is stretched on the outer peripheral frame 35 in a tensioned state. At this time, by expanding the outer peripheral frame 35, the sheet 5 is expanded via the frame engaging bent portion 5d. As a result, the sheet 5 is expanded in the vertical and horizontal outer peripheral directions (the directions of arrows d1 to d4 in FIG. 21). And supported in a stretched state on the frame. Further, the frame engaging bent portion 5d of the sheet 5 is put on the outer surface of the outer peripheral frame 35, and the protruding piece 36 of the outer peripheral frame 35 is inserted into the protruding portion 5c, whereby the sheet 5 and the outer peripheral frame are inserted. 35 so as not to disengage. This engagement is for preventing the sheet 5 from being detached from the outer peripheral frame 35 when the fruit is accommodated in the fruit accommodating recess 6. And the outer periphery frame 35 which attached the said sheet | seat 5 in the tension state is accommodated in the inside of the said square tray 1 (FIG. 21, 22). At this time, the lower edge of the outer peripheral frame 35 may be placed on the bottom plate 2 of the tray 1.

  Then, as shown in FIG. 21, the thermoplastic synthetic resin thin sheet 5 is positioned over the entire inner surface of the tray 1, and the fruit receiving recess 6 is supported by the outer peripheral frame 35 in a state of being lifted from the bottom plate 2. It will be in the state. Further, the upward protrusion 4 is positioned close to the back surface of the sheet 5 at a substantially central point M of each of the four fruit accommodating recesses 6, 6, 6 and 6 (FIG. 22), and the back surface side of the sheet 5 From the above, each center point M can be supported. That is, the fruit accommodating recess 6 in the central part is configured to be positioned at the substantially central part of the sheet 5 surrounded by the upward projections 4, 4, 4 and 4 adjacent in the vertical and horizontal directions. The along fruit accommodating recess 6 is configured to be positioned between the upper edge of the outer peripheral frame 35 and the upward projection 4.

  In this state, when the fruit is accommodated in the fruit accommodating recess 6, a downward force is applied to the inside of the outer peripheral frame 35 by the weight of the fruit 5, but the protrusion 5 c of the sheet 5 and the protrusion of the outer peripheral frame 35 are applied. Since the piece 36 is engaged, the downward movement of the sheet 5 is prevented by the protruding piece 36 even when the downward force is applied, and the upward protrusion is formed on the back side of the sheet 5 by the weight of the fruit. As a result, as in the first to fifth embodiments, the fruit comes into contact with the upper surface of the outer peripheral frame 35, the horizontal surface 5a of the outer peripheral surface of the fruit receiving recess 6, and the upward direction. It will be in the state supported by the horizontal surface 5a of the sheet | seat 5 of the outer periphery of the protrusion 4 and the outer peripheral surface of the said fruit accommodation recessed part 6. FIG.

  In the sixth embodiment, as in the first to fifth embodiments, the contained fruit can be supported in close contact with the sheet 5, so that the fruit is displaced from the recess 6. Damage can be prevented, and the fruit is a horizontal surface 5a between the upper edge of the outer peripheral frame 35 and the outer peripheral surface (upper outer surface) of the recess 6, and the outer peripheral surface of the upward projection 4 and the fruit receiving recess. Since it is supported in a suspended state by the horizontal surface 5a with the outer peripheral surface (upper edge outer surface) of 6, the fruit can be stored without damaging the fruit even by vibration during transportation.

  Further, as in the first to fifth embodiments, the edge H of the fruit accommodating recess 6 is formed by only an extremely thin sheet 5, and there is no supporting member on the back surface, so that the stored fruit is not present. Even if it vibrates and contacts the edge H, the fruit is not damaged (see FIGS. 20 to 22).

  Further, in the present embodiment, while the thermoplastic synthetic resin thin sheet 5 is stretched around the outer peripheral frame 35, the corrugated pieces 35a and 35a in the longitudinal direction are bent inward from the crease line 35c, thereby FIG. Folding inward as shown in a) and overlapping the corrugated cardboard pieces 35a and 35a alternately can be folded up as shown in FIG. At this time, since the thermoplastic synthetic resin thin sheet 5 is an extremely thin material, the thermoplastic synthetic resin thin sheet 5 is folded into an indefinite shape together with the outer peripheral frame 35, and the fruit housing recess 6 is also folded from the hemispherical original shape into an approximately flat shape. In this state, the outer peripheral frame 35 can be folded small with the seat 5 mounted. Therefore, if the rectangular tray 1 is also in the unfolded state, the fruit receiving tray itself can be transported in a state where both the rectangular tray 1 and the outer peripheral frame 35 are folded in a small size, and the tray itself is transported in an extremely compact state. be able to.

  Then, on the site, the rectangular tray 1 is assembled in a box shape to form the upward projection 4 as described above. Further, when the outer peripheral frame 35 is developed from the state shown in FIG. 24B to the state shown in FIG. 23, the thermoplastic synthetic resin thin sheet 5 is automatically moved outward (arrow d1) at each side by the outer peripheral frame 35. Since the outer peripheral frame 35 is opened, the outer peripheral frame 35 can be pulled to be in a tensioned state. In the stretched state of the sheet 5, each folded fruit accommodating recess 6 is unfolded and returns to a hemispherical shape as shown in FIG. Accordingly, the outer peripheral frame 35 in such a state may be incorporated inside the rectangular tray 1 as described above.

  As described above, in the sixth embodiment, the outer peripheral frame 35 to which the sheet 5 is attached can be folded small, whereby the fruit storage tray can be transported in a compact and efficient manner. Furthermore, it produces the effect that it can be easily assembled and accommodates fruit without using an adhesive or the like at the site.

  Since the present invention is configured as described above, the thermoplastic synthetic resin thin sheets 5 are adhered to the outer surfaces of the side plates 3 and 3 'such as the vertical and horizontal side plates and the upper surfaces of the upward projections 4 arranged in the vertical and horizontal directions. The sheet 5 is stretched and fixed flat on the upper surface of the rectangular tray 1.

  In that state, for example, the thin sheet 5 at the middle part of at least four upward projections 4 is heated to plastically deform only the recesses 6, and the outer sides of the recesses 6 and the outer periphery of the upward projections 4 are flat without plastic deformation. The surface 5a still remains, and the weight of the fruit accommodated in the recess 6 can be supported by the elasticity of the outer and outer flat stretched sheets.

  Even when the recess 6 of the thermoplastic synthetic resin thin sheet 5 is plastically deformed in advance by a vacuum molding method or the like, the outer surface of the upper edge of the recess and the outer peripheral surface of the upward projection are still flat surfaces without plastic deformation. Since it remains, there exists an effect which can support the weight of the fruit accommodated in the recessed part with the elasticity of the said flat tension sheet | seat of the said outer side and outer periphery.

  In addition, the concave portions of the two upper and lower trays can be opposed to each other, and fruit can be accommodated in the opposed concave portions, and the upper and lower opposed concave portions can vibrate independently in the vertical direction, and the opposed concave portions suppress vibration. There is no fear that fruit can be prevented from being damaged by free up-and-down vibration.

  Moreover, since the accommodation fruit is hold | maintained in the state closely_contact | adhered to the up-and-down opposing recessed part, the shift | offset | difference of the left-right direction of a fruit can be suppressed and damage to the side of a fruit can be prevented.

  In addition, in a thin sheet provided with a fitting frame, the tray and the fitting frame can be accommodated and transported in a compact manner, and the tray and the fitting frame can be assembled on site to be used as a fruit accommodation tray. There is an effect.

  In addition, when the number of fruit receiving recesses is small, it is possible to suspend and support the fruit only with the thin thermoplastic synthetic resin sheet stretched on the tray without providing upward projections, thereby preventing damage to the fruit. A fruit storage tray can be realized.

  Moreover, in what provided the outer periphery frame, while an outer periphery frame is folded together with a sheet | seat, it can be accommodated and conveyed compactly, and there exists an effect that a tray and an outer periphery frame can be assembled on-site and can be used as a fruit accommodation tray.

  In the above-described embodiment, the tray has been described as an example of a square shape. However, the tray shape is not limited to a square shape, and may be other shapes such as a circular shape.

  For example, 4 adjacently upward and downward projections 4, 4, 4, 4 × 6 = 24 pieces of the thin sheets 5, 5 of the trays 1, 1 and 24, 24 pieces between the central recesses 6. (2 dozens) of fruit 8 such as cocoons are accommodated, and the upper and lower central recesses 6 and 6 and the upper and lower flat surfaces 5a and 5a of the outer side are operated separately on the upper and lower sides during conveyance vibrations. Damage can be prevented.
