Description

  The present invention relates to a self-supporting box, and more particularly, to a self-supporting box that is film-wrapped by storing a container in a hexahedron-shaped box.

  For example, a hexahedral box container is often used as a small container that accommodates various small articles such as cosmetics and is displayed at a store or the like so that a consumer can easily hold it with one hand. A hexahedral box container is generally assembled into a hollow three-dimensional shape by folding a blank, which is a sheet-like sheet material made of paper or plastic, cut into a predetermined shape, along a fold line. These small box containers have a small bottom area by the bottom flap, and the bottom by the bottom flap often has an elongated rectangular shape. Moreover, since the bottom part by a bottom part flap is formed by inserting a front-end | tip insertion piece in the clearance gap between a front plate and the side surface flap folded inward, it tends to be in the state which the bottom part flap curved. For this reason, these small box containers are likely to become unstable, especially in the case of a vertically long box container, when the bottom is placed on a display shelf and displayed in a state where individual box containers are erected. It is often displayed using a dedicated display rack or display case.

  On the other hand, various techniques for improving the stability when a hexahedral box container is erected and enabling display in a self-standing state without using a dedicated display case or the like have been disclosed. (For example, see Patent Document 1, Patent Document 2, Patent Document 3, and Patent Document 4). The self-supporting self-supporting box described in these patent documents is provided with a leg self-supporting piece that protrudes downward from the lower edge of the front plate or the back plate, and is supported by these leg self-supporting pieces. Can be easily held (see FIG. 5A).

That is, the top surface front flap 24 is folded outside the top surface portion side flap 30 by bending the folding line 13h in a state where the folding line 13e is folded and the pair of top surface portion side surface flaps 30 are arranged inside. Also, the folding line 13i is bent, the top surface insertion flap 25 is inserted inside the upper edge of the back side front plate 17b, and the locking cuts 27 at both ends of the folding line 13i are connected to the top surface side flap 30. The top surface portion 29 is closed by locking to the base end locking portion 30a.

  Further, as shown in FIG. 1 and FIGS. 2A and 2B, the self-standing box 1 of the present embodiment has an outer peripheral surface of the hexahedral box 10 after accommodating the contents and closing the top surface portion 29. By mounting the resin film 12 so as to cover the container, the product is commercialized in a state where it is possible to prevent the contents from being tampered. That is, the resin film 12 such as a shrink film or a wrapping film is mounted so as to be wound around the outer peripheral surface of the box 10 while maintaining a predetermined tension, for example, using a known apparatus or method.

  And according to the self-supporting box 1 of this embodiment provided with the above-mentioned structure, even when the outer peripheral surface of the hexahedral box 10 is covered and the resin film 12 is mounted | worn, it can stand in a stable state.

  That is, according to the present embodiment, the self-supporting box 1 is bent at both ends of the lower end edge portion of the front plate 17b on the back side at the portions of the folding lines 13c and 13d, and the front plate 17b on the back side A corner leg piece 20 is provided that protrudes from the lower end of each corner of the pair of side plates 15 with an L-shaped cross-sectional shape, and the corner leg piece 20 is a lower edge of the front plate 17a on the front side. Together with the leg piece 21 provided to project downward from the part, a supporting leg part is configured when standing on the placement surface.

  Therefore, according to the self-standing box 1 of the present embodiment, the resin film is formed on the outer peripheral surface of the hexahedral box 10 as shown in FIG. 4 due to the large shape retaining rigidity of the corner leg piece 20 having an L-shaped cross section. It is possible to effectively avoid the corner leg piece 20 from being tilted so as to fall inward due to the inward pressing force due to the tension at the time of winding 12. As a result, for example, when the resin film 52 is attached to the conventional self-standing box 50 having the leg self-supporting piece 51 shown in FIG. 5A, the leg self-supporting piece 51 is made of resin as shown in FIG. It is possible to prevent the film 12 from tilting inward due to the tension of the film 12 and easily falling down, and to make the self-supporting box 1 stand in a stable state.

  Further, in the self-standing box 10 of the present embodiment, by providing the corner leg piece 20, a hole is opened in the root portion of the corner leg piece 20 at the bottom 14 of the hexahedral box 10. Since the resin film 12 is mounted so as to cover, the entry and tampering (mischief) of foreign matters such as dust through these holes can be effectively prevented.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, it is not always necessary to form locking cuts at both ends of the fold line between the bottom front flap and the bottom insertion flap, and it is necessary to provide a base end locking portion at the base end portion of the bottom side flap Is not necessarily. When the base end locking portion is not provided at the base end portion of the bottom side flap, the leg piece provided at the lower end edge of the other front plate is moved beyond the fold line on both side edges of the other front plate. By including the corner leg portion bent into a cross-sectional shape, the shape retention rigidity against the pressing force when the resin film 12 of the leg piece is wound is improved, and the self-supporting box becomes more independent in a more stable state. It becomes possible to make it. Moreover, the blank for forming a self-supporting box may be blanks made of paperboard, etc. besides plastic.
