Description

[Detailed Description of the Invention] The present invention relates to a box that can prevent gaps from forming between the adhesive parts of the bottom and lid. This box relates to a smaller box characterized by forming protrusions protruding on the front or back side by embossing the cover plate, bottom plate, and tongue at predetermined positions from the front or back side. be.

For boxes where the top and bottom widths of the lid plate, bottom plate, and tongue piece are smaller than the left and right widths of the side plates, when these are attached to each other in the construction of the box, there will be a gap in the designated area corresponding to the paper thickness of the box. For example, when powder or the like is stored, the powder or the like leaks out from this part.

The box according to the present invention relates to a completely new technology developed in view of the drawbacks of the prior art.

One embodiment of the box according to the present invention will be explained in detail with reference to the drawings. In Fig. 1, A is a blank plate of the box according to the present invention,
An adhesive piece 1, a front plate 2, a side plate 3, a rear plate 4, and a side plate 5 are arranged in sequence, and lid plates 6, 6' and bottom plates 7, 7' are attached to the upper and lower ends of the front and rear plates 2, 4, and the side plates 3 Tongue pieces 8 and 8' are connected to the upper and lower ends of ゜5 through folded lines, respectively, and the vertical width a of the lid plate 6, bottom plate 7, and tongue piece 8 is larger than the horizontal width of the side plates 3 and 5. It is configured small.

Next, reference numerals 9 and 10 are back side convex portions having a height of approximately one half of the paper thickness, which are embossed from the front side with a certain width on both inner surfaces of the lid plate 6' and the bottom plate 7', respectively. 12 is the convex portion 9 embossed from the back side on one side of each of the tongue pieces 8 and 8'.
, 10, and is provided at a position where it can overlap with the back side protrusions 9, 10 when constructing the box.

Since the box according to the present invention has the above-mentioned structure, as shown in FIGS. 2 to 4, the box is assembled into a case shape, and then the tongue pieces 8 and 8' are folded back. When the lid plate 6 and the bottom plate 7 are folded thereon, and the lid plate 6' and the bottom plate 7' are then folded over the lid plate 6 and the bottom plate 7, the tongue piece 8
, 8' and the rear side protrusions 9, 10 of the lid plate 6' and the bottom plate 7' are in close contact with each other, and in this state they are adhered, so that the lid plates 6, 6' and This makes it possible to completely seal the gap that occurs in the polymerized area.

As shown in FIGS. 5 to 8, the invention in the above embodiment is further improved by cutting out both outer corners of the cover plate 6 and the bottom plate 7 to form a notch 1.
When applied to blank board B with 3.14,
As is clear from the figure, by shaping the protrusions 9, 10, 11, and 12 to match the notches 13 and 14, it is possible to more completely close the gap between the lid and the bottom. .

As mentioned above, in the box according to the present invention, a portion of the tongue piece, bottom plate, and lid plate are embossed from the front and back surfaces to form a convex portion approximately half the thickness of the paper, so these convex portions are mutually connected. By matching and pasting, the gap that occurs at the lid and bottom can be completely filled, so products such as powder can be stored, and the top and bottom widths of the lid plate, bottom plate, tongue piece, etc. It's small and good, so you can save a lot of cardboard,
It has characteristics such as being able to be mass-produced at low cost.
