  Hereinafter, a cardboard tray with a partition according to an embodiment of the present invention will be specifically described with reference to the drawings.

  As shown in FIG. 1, the inner-partitioned corrugated cardboard tray T has a cruciform shape inside the tray composed of the bottom plate 1, the front and rear side plates 2 </ b> A and 2 </ b> B, and the left and right side plates 3 and 3. The horizontal partition plate 4 and the vertical partition plate 5 which are arranged in a crossed manner are divided into four storage chambers 10... And the left and right end portions are strip-like upper plate portions 61 and the end portions 2a and 2a of the front and rear side plates 2A and 2B. A handle frame 6 having a downwardly open U-shape is formed.

  Thus, the cardboard tray T with the inner partition is three-dimensionally assembled from the folded form F in the semi-assembled state shown in FIG. 3 using the single punched cardboard sheet S shown in the developed state in FIG. 2 as a raw material. ing.

  The punching corrugated cardboard sheet S shown in FIG. 2 has front and rear side plates 2A and 2B connected to each other between the front and rear ends of the upper plate portions 61 and 61 constituting the left and right handle frames 6 and 6 via a folding line a. A horizontal partition plate 4 is connected between the quadrant connection pieces 61a and 61a projecting from the central portion on the inner edge side of the upper plate portions 61 and 61 via a broken line b, and the horizontal partition plate. A vertical partition plate 5 is connected to 4 through a cutting line p. Further, the lower edge side of the rear side plate 2B is connected to the rectangular bottom plate 1 via a folding line c, and left and right side plates 3 and 3 are connected to the left and right sides of the bottom plate 1 via a folding line d. Furthermore, clue recesses 21 are formed on the upper edges of the front and rear side plates 2A and 2B at two left and right positions, respectively.

  Further, folding flaps 62 are continuously provided on the outer edge side of the upper plate portion 61 of each handle frame 6 via double folding lines e, and lock pieces 62a are provided at both end portions on the outer edge side of the folding flap 62. 62a projectingly, and a semicircular finger-hanging notch 62b is formed at the center on the outer edge side. Further, the horizontal partition plate 4 has a notch engaging portion 41 that is recessed from the upper end and has a substantially V-shaped lower portion 41a in the center portion in the longitudinal direction (left and right direction), and a lower edge side via a folding line f. A paste margin piece 42 is provided continuously. The vertical partition plate 5 is divided into a central strip portion 5a and side strip portions 5b, 5b by two parallel folding lines g, g along the longitudinal direction, and the side strip portions 5b, 5b side at both longitudinal positions. A pair of support protrusions 51... That continuously enter the central belt-like portion 5a side are formed by cutting, and cut portions 52 and 52 that enter the central side from both side edges are formed at the longitudinal center position. .

  On the other hand, the left and right side plates 3 and 3 are each divided into an upper wall portion 3a and a lower wall portion 3b by a horizontal folding line h, and at the boundary portion, the upper wall portion 3a side continuously from the lower wall portion 3b side. A pair of support projecting pieces 31 and 31 are formed by cutting, and a belt-like support flap 32 is connected to the upper edge side via a fold line i. Further, at the connection boundary portion, along the fold line i from both front and rear ends. Thus, a pair of lock grooves 33, 33 cut into the center side are formed. Furthermore, a margin piece 11 is continuously provided on the rear edge side of the bottom plate 1 via a folding line j.

  In order to assemble the punched corrugated sheet S into the folded form F shown in FIG. It is only necessary to bond the piece 42. That is, a flat rectangular tube is formed between the bottom plate 1 and the front and rear side plates 2A and 2B and the upper plate portions 61 and 61 of the handle frames 6 and 6 by the bonding of the paste margin piece 11, and the glue margin piece 42. Since the inside of the square tube is partitioned by the horizontal partition plate 4 at the center in the width direction by bonding, the front and rear side plates 2A and 2B and the horizontal partition plate 4 are formed by crushing the square tube into a parallelogram shape. Is flattened to the front and rear (forward in FIG. 3), the flat folded form F shown in FIG.

  By adopting such a folding form F, the cardboard tray T with a partition can be transported and stored in a non-bulky form, and it is efficient in a short time without the need for proficiency on the part of the user who handles packed products. Can be assembled into usage form. Moreover, in this folding form F, since the vertical partition plate 5 is connected to the horizontal partition plate 4 in a flush state, and all the constituent parts in the use form are integrated, there is a problem in assembly due to the dissipation of independent separate members. It never happens. Since this folding form F can be configured by simply bonding two places from the punched corrugated cardboard sheet S, it is easy to manufacture and structurally very simple, so that it can be converted into a usage form. High reliability can be obtained.

  Next, an assembling operation for switching from the folding form F to the use form will be described. First, the front and rear side plates 2A, 2B and the horizontal partition plate 4 that have fallen in the folding form F are raised together with the upper plate portions 61, 61 of both handle frames 6, 6, as shown in FIG. 4, and shown in FIG. Stand vertically. Thereby, the vertical partition plate 5 also stands upright integrally with the horizontal partition plate 4.

  Subsequently, the left and right side plates 3, 3 that have fallen outward are raised, and the lower wall portion 3 b is inclined inward and the upper wall portion 3 a is vertical, so that it enters the inside of the handle frame 6, and the support flap 32 bends outward and overlaps the lower surface side of the upper plate portion 61 of the handle frame 6. Then, the folding flap 62 of each handle frame 6 is folded downward and folded inward, and the lock pieces 62a and 62a at both ends thereof are fitted into the lock grooves 33 and 33 on the upper edge sides of the left and right side plates 3 and 3 and fixed. The state shown in FIG.

  Then, the vertical partition plate 5 is cut off from the horizontal partition plate 4, and the vertical partition plate 5 is folded into a substantially inverted triangular shape with the central band-shaped portion 5a as the upper surface, as shown in FIG. The vertical partition plate 5 is inserted into the notch engaging portion 41 of the horizontal partition plate 4 at the center portion, and the notch portion 52 is fitted to the lower part beyond the notch engaging portion 41, thereby the both partition plates 4 and 5 are inserted. Are arranged in a cross shape to complete the usage pattern shown in FIG.

  Thus, assembling the corrugated cardboard tray T with the partition into the usage form is an operation from the folding form F that is already in a semi-assembled state, so the procedure is extremely simple, and the farmers and dealers are familiar with it. It can be done efficiently in a short time without need.

  As shown in the sectional view of FIG. 8, the corrugated cardboard tray T with the partition thus assembled in the usage form is provided with the support protrusions 31 of the left and right side plates 3 in the respective storage chambers 10 partitioned by the partition plates 4 and 5. The support projecting pieces 51 of the vertical partition plate 5 are in a state of projecting obliquely upward from the left and right sides. Therefore, as shown by the phantom lines in the figure, when the product pack 7 such as a strawberry pack is stored in each storage chamber 10, both the support protrusions 31 and 51 support the protruding peripheral edge portion 7a of the pack 7 from both the left and right sides. Therefore, since the pack 7 is held in a state of floating from the bottom plate 1, even if pressure or impact is applied during handling such as transporting or carrying the tray, the pressure or impact is directly applied to the pack 7. It doesn't extend, and even fruit packs like strawberry packs can be protected from scratches.

  Further, as shown in FIG. 8, the support protrusions 31 of the left and right side plates 3 continuously linearly protrude from the inclined lower wall portion 3b, and the support protrusions 51 of the vertical partition plate 5 are also arranged in a V shape. Since it protrudes linearly continuously from the side belt upper part 5b and both the support projecting pieces 31 and 51 are bent significantly, the seat can be seated even if the weight of the product pack 7 is large. The product pack 7 can be stably protected without bending.

  In addition, about the vertical partition plate 5, while the notch engaging part 41 of the horizontal partition plate 4 fits into the substantially V-shaped lower part 41a, the folding state of the substantially inverted triangular shape in the longitudinal section is stably maintained. Since the notch 52 from the lower edge provided at the center in the longitudinal direction of the horizontal partition plate 4 is inserted into the lower side of the notch engaging portion 41 of the horizontal partition plate 4, a cross-shaped cross arrangement with the horizontal partition plate 4 is achieved. Keep stable.

  On the other hand, the cardboard tray T with a partition containing the product packs 7 is transported by grasping the upper plate 61 side of the left and right handle frames 6 and 6 with both hands. A triple structure in which the support flaps 31 of the left and right side plates 3 are sandwiched between the upper plate portion 61 and the folding flaps 62 is high in rigidity and strength. Therefore, even if the weight of the packed product 7 increases, it can be stably carried without fear of breakage of the handle frame 6 or bottom out. Therefore, the clue recesses 21 provided on the upper edges of the front and rear side plates 2A and 2B can insert fingers when the upper tray is lifted in a state where a plurality of trays T are stacked.

 9 to 11 show a second embodiment of a cardboard tray with a partition according to the present invention. The cardboard tray with a partition according to this embodiment is substantially a cardboard tray with a partition according to the first embodiment. The length direction is halved and has two storage chambers. Therefore, since the structure of the important part of the device is the same as that of the first embodiment of the cardboard tray with a partition, detailed description is omitted. Also, the same reference numerals are used for substantially the same portions in the drawings.

  Briefly explaining only the big difference, the middle partition plate 4 is only one which is connected to the upper plate portions 61, 61 on both sides, and a finger insertion notch portion 81 is provided at the center. Yes.

  The cardboard tray with a partition according to the second embodiment is similar to the cardboard tray with a partition according to the first embodiment. The product pack is held in a state of being lifted from the bottom plate by being supported by the support protrusions of the plate, but these support protrusions are continuous from the lower wall portion of the left and right side plates and the side belt-like portion of the vertical partition plate. Therefore, even if the weight of the product pack is large, the product pack does not buckle, and the product pack is stably protected from pressure and impact.

  Also, the assembly procedure is very simple, and there is no difficulty in learning it. Anyone can assemble the tray efficiently in a short time.

  Furthermore, since the handle frame has a triple structure and has high rigidity and high strength, and the left and right side plates 3 are firmly held by the handle frame 6 via the support flaps 31, the weight of the pack product 7 is increased. The handle frame 6 can be stably carried without fear of breakage or bottom-out.

  The corrugated cardboard tray with a partition according to the present invention includes the position, size, and number of the support protrusions 31, 51, the engagement structure of the left and right side plates 3, 3 with respect to the handle frames 6, the outer shape and dimensions of each component, and the handle frame.
