Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a packaging box that can be assembled or subdivided. More specifically, the present invention relates to a packaging box with a connecting / dividing function, in which a pair of unit boxes can be integrally connected with each other by inserting pieces protruding laterally from the small box, or the unit box can be broken by breaking the connection. It is a thing.

[Conventional technology and its problems] In recent years, paper boxes such as corrugated boxes have been used for transportation during shipping and distribution.
For convenience of storage and counting, a plurality of paper boxes individually packaged products are adjacent to each other, and adhesive is partially applied to the adjacent parts to combine them, or a connecting flap is formed integrally, Adjacent paper boxes are united by the flap so that they can be used as one package, and for convenience of sale, if necessary, the adhesive portion may be peeled off or the flap may be cut off to divide into individual paper boxes. It is required to have the set subdivision function that is made possible.

In order to satisfy such a demand, the conventional method, for example,
The assembled case shown in Japanese Patent Publication 57-88736 has been proposed. This case is provided with a locking piece protruding from one side edge of one side wall, and a slit into which the locking piece protruding from the opposite case is inserted is formed in the side edge on the opposite side of the side wall. During shipping and transportation, in order to combine the two cases into one package, the side surfaces of the two cases are abutted against each other, and the locking piece of the other case adjacent to the inside of the cut of the one case. Is folded in two and inserted, and the locking piece is expanded inside, so that the two cases are united and connected via the locking piece.

However, this case has the following problems and needs to be improved. That is, in the case, when the adjacent cases are combined and used as one package, it is necessary to fold the locking piece into two and insert the folded locking piece into a narrow cut. At this time, due to the characteristics of the paper material such as corrugated cardboard, a return elastic force that resists bending works. In other words, since the bent part of the locking piece rises (bounces) and tries to return to the original position, it cannot be inserted into the break unless the bent part is pressed with each hand, and workability is extremely high. It has the drawback of being bad. Further, since the upper part of the cut was cut off, the compressive strength of the box was lowered, and there was a problem with the bonding strength.

The present invention has been made to solve the above-mentioned problems of the conventional ones, and an object thereof is to propose a box with a connecting / dividing function that can perform both assembly and subdivision work extremely easily. Is.

Another object of the present invention is to propose a box with a connecting / dividing function, which is provided with a tearing mechanism that allows the connection to be relatively easily released even when the boxes that are collectively connected are subdivided.

[Means for Solving Problems] The box of the present invention made to achieve the above object is
A box in which two boxes can be assembled and connected by abutting their side faces against each other, and four side plates (1) to (4) continuously arranged in one direction are provided with joining pieces ( In a box formed by adhering to each other in a quadrangular tubular shape via 5), the two box bodies are juxtaposed on one side edge of the side plate (1) adjacent to the joining piece (5) in a direction in which the two box bodies are juxtaposed. Almost T
While forming a letter-shaped insertion piece (15), the T protruding from the other box opposite to the one side edge on the opposite side of the side plate (1).
The insertion piece (15) having a character shape is inserted to form the insertion hole (17) capable of connecting the two boxes, and the non-adhesive portion n is previously formed at the base of the joining piece (5). Then, the joining piece (5) and the side plate (4) are bonded to each other, and the T-shaped insertion piece (15) is provided with an inclined fold line (a) (a) having a V-shape. The locking tongue pieces (16) (16) are formed by partitioning on both wings of the insertion piece, and are further folded back on the main body of the insertion piece (15) through the inclined folding line (a) (a). It is characterized in that the tip end of the tongue piece bites into the gap of the non-bonded portion n between the side plate (4) and the joining piece (5) and is held.

[Embodiment] The configuration of the present invention will be specifically described below with reference to the drawings.

FIG. 1 is a development view showing an embodiment of the present invention formed of a corrugated cardboard sheet, and FIG. 2 is an explanatory view showing a connecting process,
FIG. 3 is an explanatory view showing a state in which two boxes are juxtaposed and the side surfaces are butted and joined together, and FIGS. 4 and 5 are an enlarged plan view of the insertion piece and a locking piece tongue as one side plate. It is an explanatory view showing the state where it bites into the gap of the joining piece and holds it.

In FIG. 1, reference numerals 1 to 4 are four side plates that are continuous in one direction and that form the side wall of the box, and 5 is a joining piece provided at the end of the side plate 1. As an example, bottom plates 6 to 9 of a one-touch lock type are connected to the lower sides of the four side plates 1 to 4, and cover plates 10 to 13 are also connected to the upper sides of the four side plates.

Further, a substantially T-shaped insertion piece 15 is formed near the center of one edge of the side plate 4 so as to project laterally. As shown in FIG. 4 in an enlarged manner, this T-shaped insertion piece is locked to both wing portions of the T-shaped insertion piece by providing a pair of inclined fold lines a and a forming a C-shape. The tongue pieces 16 and 16 are sectioned. As will be described later, the locking tongue piece 16 is used by being folded inside or outside on the insertion piece body through the folding line a.

It should be noted that at a position (base portion) corresponding to the base of the insertion piece, it is preferable to provide a subdividing means after box connection, for example, a tearing auxiliary line b including a sewing machine hole, a half cut line and the like.

By the way, in FIG. 1, reference numeral 17 is an insertion hole formed on the boundary line (fold line) between the side plates 1 and 2 corresponding to the insertion piece 15. The width H of this insertion hole is
At the time of use, the locking tongue piece 16 is formed in a size corresponding to the width S of the insertion piece body formed by folding back (see FIG. 2).

As an example, the box of the present invention comprises a flat blank as shown in the exploded view of FIG.
When this is assembled and used, the four side plates 1 to 4 are respectively bent along the fold lines into a quadrangular tubular shape and bonded. In FIG. 4, g is an adhesive portion. At this time,
The non-bonding portion n is formed in advance at the base of the joining piece 5.

Next, the adjacent bottom plates 6, 7 and 8, 9 are partially adhered to each other in a conventional manner. In this way, the two boxes are juxtaposed. On one side edge of the side plate 1 on the side adjacent to the joining piece 5 of each box, T
As shown in FIG. 2, the letter-shaped insertion piece 15 is projected in the direction in which the two boxes C1 and C2 are juxtaposed.

Then, the locking tongues 16 and 16 are previously folded back on the main body of the insertion piece via the inclined fold lines a having a V-shape,
As shown in the figure, the tip end 16a of the locking tongue piece is held by biting into the gap between the side plate and the joining piece at the corner of the box. In this case, even if you release your hand from the locking tongue 16, the bent portion, that is, the rebound due to the return elastic force against the bending of the locking tongue 16, is prevented from rebounding and the bending is maintained. Moreover, it is not necessary to hold it by hand.

Therefore, as shown in FIGS. 2 and 3, when the two box bodies C1 and C2 are combined and assembled as one package, the insertion piece 15
Can be quickly and easily inserted into the insertion hole 17. After insertion, put the hand into the box through the top opening and return the locking tongue to its original position and insert it through the insertion hole 17.
Securely connect so that 15 does not come off. After connection, tape seal as shown in Fig. 3. In this way, two boxes can be handled in the same way as one box, which is convenient for transportation / storage and counting.

On the other hand, if necessary, the two connected boxes can be separated to be used as a unit box as they are. That is, at the time of sale at a retail store or the like, when the insertion piece 15 is cut with a knife or the like along a pre-prepared tear line b at a position corresponding to the root of the insertion piece 15, the two boxes are completely connected. It can be easily subdivided into independent individual caskets.

Next, referring to FIG. 6, a modification of the flat blank constituting the box of the present invention will be described. FIG. 6 is a development view of an embodiment in which a T-shaped insertion piece 15 protruding from one side edge of the box body is cut and raised from the side plate 1. That is, the insertion piece 15 is cut out at the end of the side plate 1, that is, one side edge so as to be adjacent to the joining piece 5 so as to be continuous with the joining piece 5. Then, an insertion hole 17 is provided at one side edge on the opposite side of the side plate 1 so as to face it.

When the flat blank is assembled in the same manner as in the above embodiment, the box shown in FIG. 7 is obtained. And two boxes
When C1 and C2 are combined into one package, after cutting and inserting the insertion piece 15 from the side plate 1 as shown in FIGS. 7 and 8,
As in the case of the above-mentioned embodiment, the locking tongue pieces 16, 16 formed at the upper and lower ends thereof are folded back on the main body of the inserting piece through the inclined fold line a having a V-shape, and are engaged as shown in FIG. Tongue tip 16
The a is cut into the gap between the side plate 4 and the joining piece 5 and held. In the case of this embodiment, there is a hole 18 on the side plate 1 when the insertion piece is cut and raised, but since the holes are hidden when the two box bodies C1 and C2 are combined, the appearance is not damaged.
Further, unlike the one shown in FIG. 1, the insertion piece 15 can be cut off from the side plate 1, and the insertion piece 15 does not project from the side plate 4 in the expanded state. Therefore, not only is it excellent in material removal, but it is possible to prevent the insert piece from being torn off from its root before use.

[Effects of the Invention] As described above, the box of the present invention is provided with a non-adhesive portion in advance at the base of the joining piece, and two box bodies are provided on one side edge of the side plate adjacent to the joining piece. While forming a substantially T-shaped insertion piece that protrudes in the direction of juxtaposition, an insertion piece that can be inserted into one side edge on the opposite side of the side plate to connect two box bodies. A hole is bored, and the T-shaped insert piece is provided with an inclined fold line having a V-shape to define locking tongue pieces on both wings of the insert piece. The tip portion of the tongue piece folded back on the insertion piece body through the fold line,
The two box bodies C1, which are held by being cut into the gaps of the non-adhesive portions between the side plates and the joining pieces at the corners,
When C2 is united to form one package, it is not necessary to press the folded back tongue piece by hand, and the insertion piece can be inserted into the insertion hole quickly and easily.
Further, since the tip of the locking tongue is held in advance by biting into the gap of the non-bonded portion between the side plate of the box and the joining piece, the locking tongue is less likely to be damaged. In addition, the insertion hole is superior in that it is strong because the upper part is not separated.

Since the present invention is provided with the tearing mechanism at the base of the T-shaped insertion piece, there is an advantage that the work of dividing the two connected boxes into small pieces can be easily performed.
