Description

  The present invention provides a paper container that can open and close the open end of an inverted spire-like container using paperboard or the like with one touch.

  A typical cut flower with a large top and a narrow bottom is generally wrapped in a funnel shape using flat wrapping paper or plastic sheets as a bouquet. Was time consuming. Furthermore, when carrying the bouquet, the upper flower part is not closed, the packaging itself is less protective and susceptible to damage, and it grips the constricted lower part, i.e. the stem part. When it was carried up, there was a risk of bending of the grip part due to the weight of the flower part. In response to the above problems, by using a reverse-packed polygonal pyramid-shaped bouquet packaging box, the bouquet is protected by the shape-retaining strength of the box body and lid, and without damage due to the three-dimensional shape of the box body. A packaging box that can be carried and easily assembled has been proposed (for example, Patent Document 1).

  The packaging box for a bouquet shown in Patent Document 1 has an inverted regular quadrangular pyramid shape in the embodiment, and includes a lid piece with an opening extending to the upper edge of each side wall forming piece and a lid piece with a handle. Although the cover part is configured, the cover part of the cover part shown is assembled by inserting the insertion piece at the tip of each independent insertion cover piece into the insertion slit of the cover piece with the handle, and the labor required for assembly In addition, it takes time, and there is a concern that the insertion portion may be easily detached due to the weight of the bouquet accommodated in the box main body part or vibration of carrying.

  On the other hand, since the shape with the lower end narrowed is easy to hold, inverted pyramid-shaped paper containers are also used as large-capacity snack confectionery containers such as popcorn, which has a characteristic in the sealing structure of the upper opening Has been proposed (for example, Patent Document 2).

  The pyramidal container shown in Patent Document 2 is composed of four side plates of isosceles triangles connected in a substantially fan shape like the bouquet packaging box shown in Patent Document 1 to form a pyramidal body. The upper end of each side plate is connected to the upper end of each side plate adjacent to the upper end of the body, and each cover plate is folded into two in order and collected in the center of the upper opening. However, since it is formed on the plane of the upper opening, the three-dimensionality is poor, and there is a concern that the blockage may be released due to external pressure applied to the body.

The intersection of the virtual edge line and the virtual dividing line on both sides of the virtual dividing line is an edge vertex, and the virtual shoulder line, the both side edges, and the virtual dividing line The intersections with the virtual dividing line in the center are shoulder bending points, and the adjacent intersections are valley fold lines. And a bend formed between the valley fold lines opposed to each other with the shoulder bend point as a center by splitting the shoulder fold line on the central imaginary dividing line into two at a mountain fold line perpendicular to the outer peripheral edge. By forming a cross-shaped sealing portion in which the opening ends of the peripheral walls are converged by bending polymerization between the overlapping plates, the one side of the continuous bent polymerization plate facing the cross-shaped sealing portion is provided. A folding plate formed by bending a locking plate extending in the opposite direction from a folded plate extending at the upper end and folded back inside the peripheral wall, by folding the other opposed folded plate and the folded plate. By adopting a structure that fits and locks each other inside the part, a container with a substantially inverted polygonal pyramid shape is formed, and one large-diameter opening end is firmly sealed by a simple operation, and opening is also easy Can be unsealed and re-sealed Is stable, it is possible to form an excellent one-touch on-off vessel protection of the content items.

The bending work can be easily performed, a container having a substantially inverted square pyramid shape can be formed, and the large-diameter opening end can be firmly sealed by a simple operation.

  The invention according to claim 3 is characterized in that arc-shaped locking projections bulge and form in the direction of the bent overlapping plate adjacent to each corner side end of each locking plate. In the one-touch open / close container described in 1 or 2, the sealing state can be strengthened by forming a locking projection on the locking plate.

  The invention of claim 4 is the one-touch open / close container according to any one of claims 1 to 3, wherein the material constituting the one-touch open / close container is a cardboard material. By using it, not only can the contents be protected, but the container itself can have excellent shape retention.

  The one-touch open / close container of the present invention is a locking plate that protrudes in the opposite direction from a folded plate that extends from the upper end of each opposed folded overlapping plate in order to seal one large-diameter opening end in a cross shape Are fitted and locked to the inner side of the bent portions of the opposed folded overlapping plate and the folded plate, respectively, so that one large-diameter opening end is firmly sealed by a simple operation and hits the opening. However, the sealing can be released by a simple operation, and the resealed state is stable.

  Moreover, when it comprises using cardboard materials, such as paperboard, it not only protects the contents to store, but is excellent in the shape retention property of the container itself. Further, since thermal bonding or the like is not performed for closing the open portion of the container, a special laminated configuration and a special process are not required, and the cost is excellent.
