Description

[Detailed description of the invention] Industrial application field This invention is a packaging paper box, in particular a packaging paper whose opening lid can be opened and closed by sliding an exterior body fitted onto the paper box body. It's about boxes.

BACKGROUND ART Conventionally, as shown in FIGS. 7 and 8, this type of packaging paper box has two closing lid pieces 2 separated from each other through folds on each side of the opening edge of the paper box body X.
3 are arranged in a row, and the outer case Y is arranged in a row on these closing lid pieces 23 through the fold, and by sliding the outer case Y toward the paper box body side, each closing piece 23
is folded in half from the center, the two halves are overlapped, and the opening is closed, and by sliding the exterior body Y in the opposite direction to the above, the closed lid piece 23 is expanded. to open the opening. (For example, Utility Model Publication No. 17289, 1983).

This kind of paper box can open and close the opening with a simple operation, and even if it is opened and closed repeatedly, a secure closed state can be obtained, and the paper box body is protected by the exterior body, so it can resist external pressure. It has the advantage of increased strength and excellent durability.

Problems to be Solved by the Invention However, in such a packaging paper box, since the closing lid piece 23 is folded in half from the center, the exterior body Y is folded into the paper box from the closed lid state. When the sliding force on the exterior body Y is released when the closing lid piece 23 is expanded to a flat state and the opening is opened wide by sliding it in the opposite direction to the main body X, the elasticity of the paper Due to the restoring force, a mutually attracting force acts on both halves of the closing lid piece 23, causing the exterior body Y to be pulled back slightly toward the paper box body A side.

Moreover, this pullback force is applied to the closing lid piece 23.
is connected directly to the exterior body Y, and its half, so to speak, is an extension of the side wall of the exterior body Y, which is bent inward by 90 degrees to form a closed lid state, and further bent by 90 degrees to form a maximum open state. This is further encouraged by the fact that As a result, the degree of opening of the opening becomes small, making it difficult to take things in and out, and in order to maintain a wide open state, the exterior body Y must be pressed against the paper box body X to prevent it from being pulled back. There is a problem in that it is inconvenient to operate because it has to be done manually.

This idea was made with the aim of solving the above problems, and the closing lid piece 3
It is an object of the present invention to provide a packaging paper box in which the elastic restoring force of the packaging paper box can be minimized, the opening can be easily widened, and contents can be easily put in and taken out.

Embodiments Hereinafter, this invention will be explained based on illustrated embodiments.

Figures 1 to 6 show one of the embodiments of the packaging paper box according to this invention. A rectangular cylindrical exterior body B is integrally connected to the paper box main body A via closing lid pieces 3 that are separated from each other and are connected to each side of the opening edge of the paper box body A. That is, as shown in the unfolded state in FIG. 5, the lid pieces 3, which are closed together via vertical folds 2, 2, 2, 2, are attached to one side of each side wall 1, 1, 1, 1 of the paper box main body A. 3, 3, 3 are arranged in series, and the left side of each closing lid piece 3, 3, 3, 3 has a vertical fold 4,
4, 4, inwardly folded polymeric adhesive piece 5 through 4,
5, 5, 5 are arranged in series, and each side wall 7, 7, 7 of the exterior body B is further attached to the left side of these polymerized adhesive pieces 5, 5, 5, 5 through vertical folds 6, 6, 6, 6. , 7 are arranged in series.

The closing lid piece 3 has two parts parallel to each other in the center.
Vertical folds 8, 8 of the book are provided, and approximately dogleg-shaped notches 9, 9 are provided from the bottom end to the middle part.
9, 9 are provided so that when the exterior body B is slid, the adjacent closing lid pieces 3, 3 can be smoothly folded and unfolded without interfering with each other. Further, U-shaped cuts 17, 17 are provided at the ends of the closing lid pieces 3, 3 on the side of the paper box body A, and the tips of the tongue-shaped parts 18, 18 separated by the cuts 17, 17 are formed. Polymerized adhesive part 5 when the lid is closed
It is designed so that it comes into contact with Each side of the opening edge on the other side of the paper box body A has vertical folds 11, 11, 11,
Flaps 10, 10, 10, 10 are connected via 11, and when these are assembled, the opening edge on the other side is closed.

In the figure, 12 and 13 are the paper box body A and the exterior body B.
14 is a horizontal fold line of the paper box body A, 15 is a horizontal fold line of the exterior body B, 1
Reference numeral 6 denotes a decorative pattern continuously applied to the corresponding side walls 1 and 7 of the exterior body B and the paper box body A.

Therefore, in order to assemble and use the above-mentioned packaging paper box, first, from the unfolded state shown in FIG.
Vertical folds 6, 6, 6, 6 on each side wall 7, 7, 7, 7
Then, the outer case B is closed and folded outward by 180 degrees so that it overlaps the outer surface of the lid piece 3 and the paper box body A. and an inwardly folded polymeric adhesive piece 5,
5, 5, 5 to the inner surface of each side wall 7, 7, 7, 7 of the exterior body B, and each side wall 1, 1, 1,
1 is bent at 90 degrees from horizontal fold lines 14, 14, 14, 14 to form a paper box main body A into a cylindrical shape via joint pieces 12. When forming this paper box body A into a cylindrical shape, horizontal folds 1 of each side wall 7, 7, 7, 7 of the exterior body B
5, 15, 15, 15 will be folded together with the paper box body A. Next, while making one side edge of each closing lid piece 3 fit into the notch 9 of the adjacent closing lid piece 3,
The joining piece 13 of the exterior body B is adhered to the inner surface of the side wall 7 to form the exterior body B into a rectangular tube shape. Finally, paper box body A
The assembly of the packaging paper box according to this invention is completed by assembling the flaps 10, 10, 10, 10 to form the bottom part.

At the time of assembly, each of the closing lid pieces 3 has a mountain-shaped cross section with a slightly raised center than the flat unfolded state, and the paper box main body A is in an open state. Therefore, when the exterior body B is slid toward the paper box main body A, each closing lid piece 3 has each fold 2,
4, 8, and 8, the cross-sectional shape of a mountain as shown in FIG. The paper box main body A is placed in a state in which the centers of the matching lid pieces 3, 3 are in contact with each other, and the ends of the closing lid pieces 3 adjacent to the notches 9 of each closing lid piece 3 are fitted and overlapped with each other. The opening is closed. In this state, the closing lid pieces 3 interfere with each other, so even if the exterior body B is further slid toward the opposite side of the paper box body A, the parallel state of both halves of each closing lid piece 3 will not be maintained. It is maintained. Therefore,
Each closing lid piece 3 will not protrude outward unless a large amount of force is applied, but in this embodiment,
The tip of the tongue-shaped portion 18 is folded inward and overlaps the adhesive piece 5.
By abutting against the fold 4 between the closing lid piece 3, the sliding range of the exterior body B is restricted and the parallel state is reliably maintained. When the exterior body B is slid in the opposite direction from this closed state, each of the closing lid pieces 3 changes from a U-shaped cross section to a mountain-shaped cross section, and then to a flat unfolded state, and the paper box main body A is opened. It is.

In the illustrated embodiment, the closing lid piece 3 and the inwardly folded overlapping adhesive piece 5 are connected to only one opening edge of the paper box body A, but these can be connected to both end opening edges of the paper box body A. However, by connecting the exterior body B to either side, both sides of the paper box main body A may be formed into openings that can be opened and closed. Moreover, if the paper box body A and the exterior body B have similar polygonal cross sections,
It is not limited to a cylindrical body having a square cross section as in the illustrated embodiment, but may be a cylindrical body having a triangular or pentagonal cross section.

Effects of the invention This invention is based on the above-mentioned arrangement, in which the rectangular cylindrical paper box main body A and the exterior body B which is slidably fitted onto the box body A are connected via the foldable closing lid pieces 3, 3, 3, 3. Since they are connected, by sliding the exterior body B, the opening of the paper box body A can be opened and closed with a single touch. Moreover, two folds 8, 8 parallel to each side of the opening edge are provided in the center of each closing lid piece 3, and these folds 8, 8 are provided in both halves of the closing lid piece 3. Since the band-shaped portion is interposed between the two halves, the synergistic effect of the elastic restoring forces of both halves is alleviated, making it easier to open and close the opening and closing operations. Moreover, exterior body B
The distance by which the paper box is pulled back toward the main body A side is much shorter than that of conventional products, resulting in a wider opening and easier loading and unloading of stored items.

In addition to this, the packaging paper box according to this invention is
At the opening edge of the exterior body B, there is an inwardly folded polymeric adhesive piece 5.
is attached to form a double wall, which increases its strength, and has the advantage that the edge of the opening can be used as a knob when opening and closing, making it easier to open and close.
