Description

[Detailed Description of the Invention] [Field of the Invention] This invention relates to a tray-shaped packaging box in which a hexahedral box is constructed from a single blank made of paperboard, corrugated board, or the like.

[Prior art]

Conventionally, this type of box is made by joining a single blank into a so-called cylindrical shape, folding it, and supplying the box to the user side. That is, this blank is formed by alternately and continuously forming side panels and end panels, which constitute the side and end surfaces of the box, and from the top and bottom sides of these panels, the top and bottom panels, which constitute the top and bottom surfaces of the box, respectively. A flap and a bottom flap are extended, and the end edges of the side panels and end panels are joined together to form a cylindrical shape and then supplied to the user.

The user first attaches the bottom flaps of the boxes supplied in this way with staples and assembles them into a box with the top open, stores the products, etc. there, and then attaches the top flaps to open the top. Close and package the product.

However, in the case of these conventional boxes, the manufacturer cuts the blank into a predetermined shape, then folds the side panels and end panels in a certain direction along the crease, and then joins the edges with staples, etc. There must be. Furthermore, on the user's side, the upper and lower flaps must be joined when assembling and packaging the box, which requires a lot of work to manufacture and assemble the box. Also, when displaying products stored in this conventional box, raise the top flap and
The top flap is displayed with the top open, but in this case the top flap is in an extremely unstable state and often bends over the folds, closing the top and hiding the product. Furthermore, in this display state, when selling the product, it is necessary to attach the upper panel with staples, etc., and packaging requires time and effort.

[Purpose of the invention]

This idea was made to solve the above-mentioned problems with conventional boxes, and allows the manufacturer to supply the blanks by simply cutting them into a predetermined shape and making creases. The object of the present invention is to provide a packaging box that can be easily assembled and used on the side, and also allows for easy display and sale of products stored in the box.

[Structure and implementation examples of the idea]

A packaging box according to this invention is made by assembling blanks 1 as shown in FIG. First, to explain the structure of this blank 1, there is a bottom panel 2 that forms the bottom of a hexahedral box in the center, and side panels 3, 3 and end panels 4, 4 extend from two pairs of opposing sides, respectively. It has been extended.

Upper flaps 5, 5 extend continuously from the above-mentioned both side panels 3, 3, and a fold (indicated by a two-dot chain line; ) are made from both sides.

On the other hand, closing flaps 7, 7 extend continuously from the end panels 4, 4, respectively, and insertion flaps 8, 8... extend from both sides of the closing flaps 7, 7, respectively. . Furthermore, in the illustrated embodiment, auxiliary flaps 9, 9, . . . extend from the insertion flaps 8, 8, . . . toward the side panels 3, 3 in FIG.

The width w of the insertion flaps 8, 8... is set slightly wider than the depth d of the cuts 6, 6.... Further, shallow U-shaped or V-shaped grooves 10, 10, etc. are formed on the folds of the insertion flaps 8, 8, . . . and the closing flaps 7, 7.

When this blank 1 is folded to form a box, the following procedure is followed. First, as shown in Fig. 2, fold the side panels 3, 3 and the upper flaps 5, 5 sequentially inward along their folds (the inside of the box to be assembled, the same applies hereinafter), and fold each side panel into the side of the box. and the upper surface. Next, insert flaps 8, 8... and auxiliary flaps 9, 9...
After being folded inwards, the insert flaps 8,8 are folded inwards against the closing panels 7,7, and the closing flaps 7,7 are folded inwardly against the end panels 4,4. Furthermore, from this state, the end panels 4, 4 are lifted up from the bottom panel 2 and bent, and at the same time, the insertion flaps 8, 8...
is inserted into the box body through the notches 6, 6..., and the notches 6, 6... and the grooves 10, 10... are engaged. In this state, the end faces of the box body are closed by the end panels 4, 4, and the closing flaps 7, 7
are overlapped on top of the upper flaps 5, 5, and in this state, the cuts 6, 6... and the grooves 10, 10...
held by engagement with the

On the other hand, when displaying products by storing them in this box, as shown in FIG. 3, the insert flap 8,
8. Pull out about halfway, open the end panels 4, 4, and raise the upper flaps 5, 5 in this state.
Both sides thereof are hung on the kerf grooves 10, 10, . . . .
In this state, the upper flaps 5, 5 are connected to the kerf 1.
Since it is held by 0, 10, etc., it will not fall down easily. Furthermore, from this state, remove the upper flaps 5, 5 from the same cut grooves 10, 10... and fold them down, and insert the insert flaps 8, 8... into the cuts 6, 6.
Insert it all the way into the grooves 10 and 1.
By engaging 0..., the box can be closed again.

[Effect of idea]

As described above, according to this invention, the manufacturer can supply the box by simply cutting the blank into a predetermined shape and making creases, and the user can also join the upper and lower flaps, It can be easily assembled and used for packaging without any troublesome work. Moreover, products can be displayed while stored in the box, and the box can be immediately closed and packaged from the displayed state.
