Description

The present invention relates to a tray for fruit and vegetables such as a basket that is folded up from a single cardboard and in which a pack receiver for fruit and vegetables is formed for each partition section. Specifically, for each of the plurality of partitions, a fruit and vegetable pack cradle is formed to suspend the pack, and the bottom surface of the pack is lifted from the bottom surface of the tray, so that fruits and vegetables such as strawberries are crushed by their own weight and are not damaged. This is a tray for fruits and vegetables such as grapes that are high-end, brand-oriented, or discriminatory.

The present applicant has previously proposed a tray for directly placing the pack on the bottom surface of the tray without raising the bottom of the pack (Patent Documents 1 and 2). In addition, direct trays as described below are used. FIG. 15A shows a state where the pack is placed on one section of the tray, and FIG. 15B shows a mat placed on the pack. Here, the pack is, for example, a container for storing fruits and vegetables formed in a thin PET resin shape, and the mat is, for example, a rug formed by molding a film-like polyethylene resin in accordance with the dent of the pack. In this case, the tray 600C is vertically divided by the left and right divided pieces 10 and 10 protruding from the left and right side walls of the tray 600C. For example, the pack 700 is placed in one section. Here, since the pack 700 is placed directly on the bottom surface 1 of the tray 600C, the bottom 701 of the pack comes into contact with the bottom surface 1 of the tray 600C. Then, although not shown in the figure (a), the mat 800 shown in the figure (b) is placed on the bottom 701 of the pack 700 and, for example, a basket is put thereon. In this way, the mat is laid so that the wrinkles are not damaged, and the wrinkles are put on the mat. However, since the bottom of the pack is in direct contact with the bottom of the tray, the wrinkles are crushed and damaged by the dead weight of fruits and vegetables such as wrinkles.

The support piece 5 bends substantially perpendicularly to the inside of the tray from the fold lines J and J provided on the inner left and right side walls 2A, and the leading edge 511 faces the inside of the tray. On the other hand, the distal end side 512 on the opposite side is fitted so as to pierce into the grooves 42 and 42 in the left and right side walls 2A and 2A, and the curved portions 53 and 53 are formed inside the tray at the crossing portion. Is done. Thus, the support piece 5 is formed using the creases J and J as fulcrums of the lever. Therefore, since the front end side 512 of the support piece 5 is fitted in the grooves 42 and 42, the support piece 5 can support the load applied to the front end side 511 using the folds J and J as fulcrums. .

Next, FIG. 7 shows a state where the pack 700 is attached to one half of the tray 600A. Here, the half section side on which the pack 700 is mounted is referred to as the inner side of the tray 600A, and the same applies to the second embodiment. As shown in FIG. 5, the pack 700 includes a bottom 701, a lateral edge 702, a corner edge 703, a vertical edge 704, and the like, and as shown in FIG. 7, support pieces 6 and 6 formed at the four corners of the tray. , 6, 6 and the pair of left and right side walls 2A, 2A, the pack 700 is received by the cross-shaped support pieces 5, 5 provided so as to protrude inside. That is, on the rear side of the tray 600 </ b> A, the corner edges 703 and 703 of the pack 700 are received by the support pieces 6 and 6 at the inner corners of the rear front and rear side walls 3. On the other hand, at the center side of the tray 600A, the corner edges 703 and 703 of the pack 700 are received by the left and right cross-shaped support pieces 5 and 5. Here, the height dimension from the bottom surface 1 in each support piece is larger than the depth dimension of the pack. Therefore, while the four corner edges 703 of the pack are supported by the four portions of the support pieces 5 and 5 and the support pieces 6 and 6, the bottom surface 701 of the pack floats without contacting the bottom surface 1 of the tray 600A.

A state in which the corner edge of the pack 700 is supported by the cross-shaped support piece 5 will be described with reference to FIG. The cross-shaped support piece 5 is bent at a substantially right angle from the folds J and J so that the tip side 511 faces the inside of the tray, while the opposite tip side 512 is a groove in the left and right side walls 2A and 2A. Curved portions 53 and 53 are formed at portions that are fitted to pierce 42 and 42 and intersect in a cross shape. The corner edge 703 of the pack 700 is supported by the curved portion 53 of the support piece 5. The four corners 703 of the pack float from the surface of the tray, for example, 250 grams of the weight of fruits and vegetables packed in one pack while being supported at the four places of the support pieces 5, 5 and the support pieces 6, 6. Keep it in a suspended state. Further, since the outer peripheral wall of the side wall 705 contacts the curved portion 53 of the support piece 5 at the corner edge of the pack 700, the front and rear positions of the pack are determined. As a result, even if there is no dividing wall that separates the front and back of the tray, the pack does not jump or move over to the next adjacent compartment. As described above, at the upper left corner of the tray, the support piece 6 is formed from a portion of the fold line H provided in the inner left and right side walls 2A, and the tip side 61 is formed in contact with the inner sides of the front and rear side walls 3. . The corner edge 703 of the pack 700 is supported by the support piece 6.

That is, in the upper and lower central portions of the left and right side pieces 2B, the outline of the support piece 7 is constituted by cuts r, u, v, crease N, cuts v, u, and crease R in the clockwise direction. The side piece 2B is formed in a T shape by cutting out in the same manner in a triangular shape along the cuts r, t, u near the double fold line N.

The procedure for folding the tray is described below. FIG. 10 shows a state in which the pair of left and right side walls 2B and 2B and the pair of front and rear side walls 3 and 3 are folded up so as to surround the bottom surface 1 from the crease portion. In the process of erecting the side walls 2B, 2B from the bottom surface 1, the auxiliary piece 4B is sandwiched between the left and right side walls 2B, 2B in a state of being bent at right angles from the end portions of the front and rear side walls 3. In this figure, the front and rear side walls 3 and 3 are erected from the bottom surface 1, one of the left and right side walls 2B and 2B is in the middle of sandwiching the auxiliary piece 4B inside, and the other left and right side walls 2B and 2B are erected from the bottom surface 1 Thus, it is formed as a triple side wall sandwiching the auxiliary pieces 4B, 4B. By folding up in triplicate in this manner, the buckling strength in the vertical direction on the left and right side walls is improved, so that it is possible to receive a multi-stage stacking load of trays filled with fruits such as strawberries. Further, when the left and right side walls 2B from the double folds N and N are bent at right angles toward the bottom surface 1, the support pieces 6 at the four corners are bent from the part of the fold H, and the leading edge 61 is brought into contact with the front and rear side walls 3. Make contact. And the engagement piece 25 of the inner left and right side walls 2B is fitted into the hole 12 of the bottom surface 1 so that the left and right side walls 2B and 2B stand upright on the bottom surface 1, and at the same time, located at the center of the inner left and right side walls 2B. The support piece 7 is formed so as to fold out from the folds N, Q, and R and project in a reverse T-shape into the inside of the tray in a cross-sectional shape. In this way, a tray 600B is completed as shown in FIG. 11, and support pieces 6, 6, 6, 6 and support pieces 7, 7 project from the center of the inner left and right side walls 2B, 2B. Suspend the pack on the support piece.

Next, the formation and operation of the T-shaped support piece which is a characteristic configuration of the present embodiment will be described. As described above with reference to FIG. 11, the support piece 7 is formed on the inner left and right side walls 2 </ b> B so as to protrude toward the inside of the tray, and an enlarged state thereof is shown in FIG. 12. The figure shows a state viewed from the inside of the tray, where the first piece 71 of the support piece 7 bends inward from the portion of the crease N provided on the left and right side walls 2B, and then from the portion of the crease R at the tip of the first piece 71. The second piece 72 bends to the opposite side, and the back of the second piece 72 leads to a crease Q provided on the inner left and right side walls 2B. In summary, the support piece 7 has a first piece 71 and a second piece 72 that are bent through the folds N, R, and Q, and the cross section is formed in a U shape and protrudes in an inverted T shape inside the tray. Tip sides 721 and 721 are formed on both sides of the second piece 72 where the first piece 71 intersects so as to sandwich the crease R, and bending points 722 and 722 are formed at the bent portions of the first piece 71 and the second piece 72. Formed on both sides. Here, the crease Q is preferably a half-cut corrugated board when the left and right side walls 2B are half-cut, but a normal crease may be used. Thus, the support piece 7 is supported by the crease N at the upper side and supported by the creases R and Q at the lower side. Therefore, the load applied to the tip side 721 of the second piece 72 can be supported by the link mechanism in which the cardboard is bent. Further, when folding from the corrugated board to the tray, the left and right side walls 2B and 2B stand upright on the bottom surface 1, and at the same time, the tray is automatically folded to form T-shaped support pieces 7 on the inner left and right side walls 2B. The efficiency of the work of folding up is improved.

Next, FIG. 13 shows a state in which the pack 700 is attached to one half of the tray 600B. As shown in FIG. 5, the pack 700 includes a bottom 701, a horizontal edge 702, a corner edge 703, a vertical edge 704, etc., and as shown in FIG. 13, support pieces 6, 6 formed at the four corners of the tray. , 6, 6 and the support pieces 7, 7 formed inside the pair of left and right side walls 2B, 2B, receive the pack 700. That is, the corner edges 703 and 703 of the pack 700 are received by the support pieces 6 and 6 at the left and right corners of the front and rear side walls 3 on the rear side of the tray 600B. On the other hand, on the center side of the tray 600B, the corner edges 703 and 703 of the pack 700 are received by the T-shaped support pieces 7 and 7 formed on the inner left and right side walls 2B. Here, the height dimension from the bottom surface 1 in each support piece is larger than the depth dimension of the pack. Therefore, while the four corners 703 of the pack are supported by the four portions of the support pieces 7 and 7 and the support pieces 6 and 6, the bottom surface 701 of the pack floats without contacting the bottom surface 1 of the tray 600B. Can keep the state.

A state where the corner edge of the pack 700 is supported by the T-shaped support piece 7 will be described with reference to FIG. The T-shaped support piece 7 protrudes in a U-shaped cross section from the portion of the crease R to the inside of the tray. Tip sides 721 and 721 are formed so as to sandwich the crease R, and bending points 722 and 722 are formed in the bent portions of the first piece 71 and the second piece 72 so as to sandwich the crease R. The corner edge 703 of the pack 700 is supported by the front end side 721 of the support piece 7 and is kept suspended from the surface of the tray. In addition, the pack 700 is positioned because the outer peripheral wall of the corner edge 703 comes into contact with the curved point 722 of the support piece 7. As a result, even if there is no dividing wall that divides the front and back of the tray, the pack does not jump or move to the next adjacent compartment.
