Description

[Detailed description of the invention] (Industrial application field) This invention relates to an assembly box for fruits, specifically a container for storing fruits such as strawberries, loquats, figs, persimmons, apples, etc., and is a small box. You can connect two pieces together to make a large box, or combine the large box into a small box 2.
This invention relates to an assembly box for fruit that can be divided into individual pieces.

(Prior art) Conventionally, large or small containers of various shapes have been widely used as containers for fruit, regardless of the material. For example, as shown in FIG. 6, a structure in which a plurality (mainly two) of small assembly boxes are connected in parallel from one base material (cardboard) is known.

(Problem that the invention aims to solve) However, although this product has some advantages compared to mass producing large and small containers,
Such two parallel (connected) small assembly boxes (hereinafter referred to as parallel containers) consist of side walls surrounding two bottom parts 40 and 40' made of a single piece of cardboard, as shown in FIG. Since the two containers are prevented from coming apart through a triangular engagement piece 46' between the lower parts of the side walls, there is no need to lay or lay a known formwork (see FIG. 5) thereon.
For example, when the end user does not need the entire amount of strawberries stored in the parallel containers, but requests 1/2 of the amount, as is often the case when strawberries are stored side by side or randomly and displayed at a store. In this case, the two pieces had to be cut from the connected part by an appropriate method. Therefore, due to the frequent occurrence of such cases, if a large number of strawberries are requested due to the frequent occurrence of broken containers, it will be necessary to produce a large number of broken containers, making it difficult not only to carry but also to transport. It was accompanied by inconveniences such as being bulky. Therefore, a solution to this inconvenience has become an urgent issue.

(Means for Solving the Problems) In order to solve the above problems, this invention uses a single base material to integrally form the box bottom and the surrounding side wall plates, and also folds the side wall plates in half to create a double layer. A box was assembled by forming a side wall and having a connecting piece and an external attachment piece protrude at right angles from the end of the side wall on one side. When connecting two boxes, the sides with the connecting pieces should face each other, and each connecting side should be moved forward along the inside of the external attachment piece of the other box. It is sandwiched between the two side walls. On the other hand, an engaging recess is formed in advance on the upper end surface of the connecting piece, and delta-shaped corner reinforcing pieces are integrally extended from the side wall plates at the top of the four corners of the box so that they can be bent horizontally. The piece is provided with an engaging piece at a position and size that can be engaged with the engaging recess of the connecting piece, and the engaging piece is bent in a hanging shape to form an edge frame piece at the upper part of the double side wall. It is configured to be inserted through the fitting hole and engaged with the engagement recess of the lower connecting piece. The details are as stated in the claims for utility model registration.

(Function) In this device configured as above,
The box can be easily assembled from a single base material. Naturally, the box can be used alone. Next, when you want to connect two boxes to make a large box,
When each connecting piece is advanced along the inside of the outer attachment piece of the mating box with the protruding sides of the connecting pieces facing each other, the connecting piece is sandwiched within the double side walls of the mating box. Therefore, if you bend the corner reinforcing piece of the mating box horizontally and insert the engaging piece into the fitting hole, the engaging piece will fit into the engaging recess of the connecting piece, so the connecting piece cannot be removed. , both boxes are connected together. The external attachment piece serves as a reinforcing material for the base portion of the connecting piece of the mating box.

(Example) An example of this invention will be described based on the drawings.
Figure 1 is a developed plan view of the base material of the box, and the following explanation of the box is also based on this plan view. is expressed as inside.

Box bottom 1 made of corrugated paper or other thick paper
is formed into a long rectangular shape from front to back, and a front edge line 1A and a rear edge line 1B are set as folding lines at the front and rear edges, and front and rear edges are set outside the front and rear edge lines 1A and 1B, respectively. Side wall plates 2, 2' are extended. In addition, a left side edge line 1 is placed on the left and right side edges of the box bottom 1.
C and right side edge line 1D are each set as a folding line, and left and right side wall plates 3 and 3' extend outward from the folding lines, respectively. The front and rear wall plates 2, 2' have a width W2 equal to or more than twice the set height of the box and two overlapping base materials.
The front and rear wall plates 2, 2' are set to be approximately symmetrical.

Inward fold lines 2A, 2A are set outward from the front and rear edge lines 1A, 1B by an amount corresponding to the height of the box, and outwardly there are edge frame pieces 2B having a width W2 approximately twice the thickness of the base material.
2B is formed, and lower inward fold lines 2C, 2C are formed on the outside thereof.

In addition, on the left side inside the inward bend lines 2A and 2A, the boundary lines 2F and 2F are on the extension line of the left side edge line 1C.
A connecting piece 5 is formed on the left side of the front wall plate 2, and a connecting piece 6 is formed on the rear wall plate 2'. The length of the connecting piece 5 is set in consideration of the strength after connecting. For example, if the box is for strawberries, the bottom of the box is 18 x 13 cm, and the height is about 5 cm, the length of the connecting piece 5 is set. A height of about 6 cm is sufficient. Therefore, the connecting piece 5 has an arcuate tip,
An engagement recess 5A is formed by a notch in the end surface that becomes the upper end when the side wall plate 2 is raised up.
Further, the length of the external attachment piece 6 is set to about 10 to 15 mm because if it is too long, it will bend and the strength will be weak.

Fitting holes 7, 7, . . . are formed in a penetrating manner at both end edges of the edge frame pieces 2B, 2B. The fitting hole 7
. . . is for fitting an engaging piece 9 of a corner reinforcing piece 8 to be described later.

At the left and right edge portions of the front and rear inner wall plates 2D, 2D, inward fold lines 2G, 2G...
... is set and the inner folding pieces 4B, 4B, 4 are set on the outside thereof.
C, 4C are formed. Note that the symbol S in the figure is a notch, into which the portions a, b, c, and d of the left and right inner wall plates 3D in FIG. 1 are fitted when assembled.

Therefore, the front and rear wall plates 2, 2' have an inward fold line 2A.
and inner wall plate 2D, folded from the lower inner fold line 2C,
When 2D are stacked and stood up, it becomes double front and rear side wall plates 2, 2'. Therefore, the inner folding piece 4A,
When 4B and 4C are folded inward at right angles from the inner fold lines 2E and 2F, the inner fold pieces 4A to 4C form the corresponding left and right edge lines 1.
C, along 1D.

On the other hand, the left and right side wall plates 3, 3' are set to have the same length as the left and right side edge lines 1C, 1D, and have the same width as the front and rear side wall plates. Therefore, the component settings are the same as those for the front and rear wall panels, and the code is at internal fold line 3.
A, edge frame piece 3B, lower inner fold line 3C, and inner wall board 3D.

At both longitudinal end edges of the left and right inner wall plates 3D, 3D, from the end faces to the inward fold lines 3A, 3A,
Arc-shaped cutting lines 8A, 8A, . . . are formed to form delta-shaped corner reinforcing pieces 8, 8, . The length of each corner reinforcing piece 8 from the inward fold line 3A is set to match the length from the inward fold line 2E of the front and rear wall plates to the inner end of the fitting hole 7, and each corner reinforcing piece 8... A hook-shaped engagement piece 9 large enough to fit into the fitting hole 7 is formed at the front-rear end of the fitting hole 7. Further, insertion holes 10, 10 are formed in the longitudinal middle portions of the inner wall plates 3D, 3D, into which end portions of partition plates (not shown) are fitted.

In the above configuration, when the left and right side wall plates 3, 3' are stood up and the inner wall plates 3D, 3D are bent inward from the inner fold line 3A and the lower inner fold line 3C, the inner fold pieces 4A, 4B of the front and rear side wall plates 2, 2' are bent. , 4C are pressed against the left and right side wall plates 3, 3', and the left and right inner wall plates 3D, 3D's longitudinal ends a,
Front and rear inner wall boards 2 whose b, c, and d portions correspond to this
Since it bites into the notch S portion of D and 2D, four side walls are formed.

Next, each corner reinforcing piece 8... is horizontally bent inward, and the engaging piece 9 is further bent downward, so that each engaging piece 9... is fitted into the fitting hole 7 of the edge frame pieces 2B, 2B facing each other. . . , and the fruit assembly box 11 is completed as shown in FIG. 2. That is,
The corner reinforcing pieces 8 have the function of fixing the connections between the front and rear and left and right side wall plates.

Next, in Fig. 2, two fruit assembly boxes 1
1 and 11, if the protruding sides 3 of the connecting pieces 5, 5 are opposed to each other, each connecting piece 5, 5 will be opposed to the outer attachment pieces 6, 6 of the mating box. Therefore, since there is a space indicated by the symbol W1 in FIG. When inserted into the space W1 along the inside of the connecting pieces 5, 5 are inserted between the rear wall plate 2' and the inner wall plate 2D inside thereof. Therefore, pull out the engaging piece 9 of the corner reinforcing piece 8 near the external attachment pieces 6, 6 from the fitting hole 7, insert each connecting piece 5, 5 to the base, and then fit the engaging piece 9. When reinserted into the mating hole 7, the lower ends of the engaging pieces 9 fit into the engaging recesses 5A, 5A of the connecting piece 5 as shown in FIG. 4, so the connecting pieces 5, 5 cannot be removed. Since this is not possible, the two boxes 11, 11 are combined into one large box as shown in FIG. When it is desired to separate the combined large box into two small boxes, by moving the engaging piece 9 of the corner reinforcing piece 8 upward in FIG. 4, the engaging piece 9 and the engaging recess 5A can be engaged with each other. Since this is released, the connecting piece 5 can be removed and separated.

Therefore, during shipping and sales, the two boxes may be combined, and for customers who only need a small amount, they may be separated into smaller boxes.

(Effects of the invention) As detailed above, this invention has the following excellent effects.

(1) The side wall plate has a double structure, and a connecting piece and an external attachment piece are made to protrude from one side of the box, and each connecting piece of the two boxes is placed along the inside of the external attachment piece of the other box. The connecting body is designed to connect two boxes by inserting them between the double side wall plates and fitting the engaging piece of the mating box into the engaging recess formed at the upper end of the connecting piece. This has the advantage that it is easy to form a large box and it can be firmly connected.

(2) Since the external attachment piece reinforces the base of the connecting piece of the mating box, sideways shaking of the combined box is prevented and the combined strength of the combined box is improved.

(3) Since it can be produced by punching and molding a single base material, mass production and lower production costs can be expected.
