1a-1b will now be described. Box blank (1) is first flattened Yes (see Figure 1a), the center part that forms the bottom of the cardboard box (or the top of the lid) 2) and a rim portion (3). The rim portion (3) is approximately perpendicular to the bottom surface (2). When folded along the crease line (4), it becomes the side wall of the box (or lid).

In the box blank (1), the two opposing rims (3) each have a tab (5 ). Fold the tabs (5) around the corners of the box in the manner shown in Figure 1b-1a. be bent. In addition, the tab (5) external sill may be cut off for practical and aesthetic reasons. It is. As those skilled in the art will appreciate, there are various ways of arranging the tabs (5). However, as will be explained later, the important thing is that when the box blank is folded, the tab (5) As shown in Figure 1c, it overlaps other parts and is attached to adjacent parts of the box. It is to constitute a multilayer.

Each tab (5) contains a slot (6) which extends from the outer edge of the tab to the interior of the tab. In addition to having a constant length, the tab is perpendicular to the outer edge of the tab. Alternatively, you can change the outer edge of the tab to A slot-shaped opening (not shown) is cut inside the tab. Also box block When the rank is assembled, the rim part (3) that comes into contact with the tab (5) is the length of the tab (5). Has an elongated hole (6) or opening corresponding to the position and dimensions of the hole (6) or opening Therefore, when assembling the box blank, the long hole (6) or opening of the rim should be connected to the tab ( 5) Matches the elongated hole (6) or opening and serves as an extension of the opening facing inside the box. Ru.

Fold the box blank (or lid blank) in the manner shown in Figures 1a-1b. After that, use the clip (7) to grasp the overlapping part of the tab (5) and the rim part (3). I can do it. The clip embodiment shown in Figure 2 is approximately rectangular and parallel to each other. It is provided with two face walls (8) having two-handed faces.

In addition, the spacing between the walls on both sides is such that the overlapping part of the tab (5) and rim part (3) is fixed almost closely. It is designed so that you can wear it. One end of the double-sided wall (8) of the clip (7) is the end wall (9). The two-sided wall is connected to the tab (5) using the free end opposite to this end wall. The rim part (3) can be fitted inwardly. Also, each clip (7) The web (10) starts from the end wall (9) and extends from the double-sided wall (8). Extending along the center line of the inner surface and perpendicular to the end wall (9), the free end of the double-sided wall (8) It is preferable to reach near the edge. The web (10) is connected to the inner surface of the double-sided wall (8). It has a thickness and length corresponding to the width and length of the elongated hole (6). Current However, the clip (7) is inserted onto the tab (5) and the rim (3) in the manner shown in Figure 2. If the web (10) is inserted in the elongated hole (6), the tab The tab (5) and the rim portion (3) are effectively gripped by the clip (7). Also on the web (10) is inserted into the elongated hole (6), so the clip (7) will fit along the side of the box. It will not slide around.

To facilitate the operation of the clip (7) 1. As shown in the example of FIG. A thick wall portion (1 1) can be installed.

In the embodiment shown in Figures 3a-3c, the circular double-sided wall (8) is connected to the web (10). It is joined with chisel. Also, in order to make it easier to attach the clip, It is preferable to chamfer the outer peripheral edge and the opposing surface as shown in the drawings. Further The clips according to figures 3a-3c are placed on the outside of one side wall in the position of attachment to the box. It contains a circular button (11'), and the button should be placed as close to the center of the face wall as possible. Deploy. Also, the outer end of the button has a larger diameter than the part closer to the face wall (8). (for example, forming the button as a short column with a circular outer flange). Bota (11’) is used when hanging a band with buttonholes around a box with a lid. use.

Figures 4a-4d show another embodiment, also circular, but in which the clip is Contains only one complete face wall (8).

In other words, as shown in Figure 4d, the surface wall that becomes the inner surface when attached to the box is a semicircular surface. wall, connected to a fully circular external wall by an end wall (9') spanning the entire diameter. It is.

Therefore, as shown in Figure 4d, half of the outer wall (8), when mounted on the box, Extends upward from the top edge of the box to support higher boxes stacked on top of lower boxes Therefore, a large number of cardboard boxes can be stacked using the clips shown in Figures 4a-4d. It can be repeated. Therefore, from the clip according to figures 4a-4d the web (1 0) is omitted and used exclusively for stacking boxes, and at the same time, it can be used for various embodiments according to the present invention. It is possible to grasp the bent part of the box blank (1) using any clip. can.

The clip embodiment shown in Figure 5 is rectangular and relatively elongated. This kind of chestnut When installed in the box, the cup has a face wall (8) extending downward and a face wall (8) extending upward. It includes a face wall (8') that extends horizontally therein and an end wall (9) that extends horizontally therein. Ma The webs (10), (10') extending longitudinally in the center of the clip are It extends upward and downward from the end wall (9). As is clear from Figure 5, this format The clip secures the box blank to the lid and secures the lid in place on the box. Use it for tricks. Rachirun, change the shape of the clip in Figure 5 to circular. It is also possible to provide a button (II').

In the embodiment shown in Figures 8a-6d, one of the face walls (8) is removable. Similarly to the use of snaps, the clasp is connected to the face wall (8) of the eye. It is attached to the web (1o).

Note that this removable face wall has a mating face wall (8) that is a box blank rim part (3). and tab (5), and as shown in Figure 6a, the other side wall After the web (10) is inserted into the alignment opening of the overlapping section, the web (10) ). The web also extends over most of the diameter of its connecting face wall (8). It is shown in Figures 6a-6d as a long, narrow member extending over 1000 mm. The web is also As shown in Figures 6a-6d. The web also has 7 characters as shown in Figures 6a-6b. The cross section of the shape is divided into two vertically by a groove. The tip of the slot is a web (1 0) is close to the internal plane of the face wall (8), and said slot has a web (10 ) is open at the free edge. In other words, the web (10) has two legs in the above slot. It is divided. These legs have a sawtooth-like cross-section at their distal ends and an edge (1 2) and oriented in the direction shown in Figures 6a-6b. Web (1o ) and the surface of the serrated edge (12) facing the connecting face wall (8) of said face wall (8). The distance from the inner surface is determined by the thickness of the two members (3) and (5) of the box blank and the removable type. This corresponds to the total thickness of the face wall (8).

The removable face wall (8) has an elongated opening (13) along its diameter; The dimensions of the section correspond to the dimensions inward from the edge (I2) of the web (10). Therefore The web of the connecting face wall (8) of the web (10) is connected to the box blank member (3). , (5), the web (10) aligns with the box blank. Because it protrudes from the surface of the overlapping part of members (3) and (5) that is separated from the above-mentioned surface wall (8), , a removable face wall (8) with an opening (13) has two serrations of the web (lO). Slide on the edge1. between the inner edge of the web and the surface of the overlapping portion.

As will be clear to those skilled in the art, the two legs of the web (10) are attached to the removable face wall (8). When inserting it into the web (10), it first curves and joins, so the removable face wall (8) It is inserted through the edge (12) of the web. After that, both legs rebound and separate from each other. Therefore, when the insertion is completed, the removable face wall (8) has a serrated edge with the surface of the overlapping part. It is locked between the inner surface of (12). The removable face wall (8) to the web (10) To facilitate insertion, the opening (13) in the face wall is chamfered as shown in Figure 6b. It is desirable that the opening widens toward the inside of the face wall.

The shape of the web (10) in the above embodiments does not necessarily have to be the rod shape shown in Figures 6a-6d. There's no need to. For example, forming a cylindrical web with circular serrations on the free end. It is also possible to provide a flange (12). In this case, the removable face wall (8) Of course, the opening (13) is also circular and has matched shape and dimensions. Ru.

The main advantage of the embodiment shown in Figures 6a-6d and the modifications described above is that the web (10) Openings or slots (6) for receiving the box blank members (3), (5 ) can be cut not only at the outer edge but also at other locations. With this advantage , the strength of the box blank (1) (or the strength of the box lid) - is the opening at the free edge. Naturally, this is superior to blanks with grooves (6).

Figures 7a-7d show how to overlap boxes or lids using clips according to the invention. This shows how to fix the tap part. However, in this application, the overlap part is larger than the free edge. They are separated by a large distance, and gluing is limited to cases where they will not peel off even if they are not joined using adhesives, etc. heavy First, cut out a long hole (6) in one of the parts to be fitted, and then insert a groove (14) separately. It will be done. Next, as shown in Figure 7b, use the groove (14) and the fold line (15) to The member is then bent to form a triangular surface (16). It is clear from Figures 7a-7b that As shown in FIG. When the material is bent from the plane of the base paper by the method shown in A long hole (6) is connected to the opening. Also, an opening (17) is provided in the mating member. Notch or die cut, do. The size of the opening (17) is determined by holding the clip horizontally. The shape of the opening (17) is such that it can be inserted into the face wall (8) of the clip. ) is preferable. The mating member also includes, as shown in FIG. 7c, An elongated hole (6) communicating with the opening (17) is cut out. In this case, the mating member is a box or the side of the lid (5). The reason is that box blanks are used to This is because the attachment (5) is easily accessible from the outside once the lid is made. Ru.

Now, in order to fix members (3) and (5) in the manner shown in Figure 7d, click the clip. Use the After abutting members (3) and (5), insert the clip as shown in Figure 7d. , into the opening (17) of the member (5). The inserted clip is slightly tilted. and presses the lower edge of the triangular surface (16) according to Figures 73.7b and 7d. , the triangular surface (16) is somewhat protruding near the fold line (15). As a result of this The clip has a web (10) (the shape of which is shown in FIG. 2 or 3, for example). ) When viewed from a projection plane parallel to members (3) and (5), the shape of the elongated hole (6) is The orientation is such that it extends on the image line, so open the clip completely horizontally. It can be inserted into the mouth (I7) and further pushed down along the elongated hole (6). . This creates a gap between the two walls (8) of the clip, as shown at the bottom of Figure 7d. Members (3) and (5) are fixed. As a result, the triangular surface (16) is inside the member (5). direction, and the clip is pressed somewhat upward in the elongate (6). The clip thus grips the triangular surface (16) by its inner side wall (8).
