Embodiments will be described below with reference to the drawings showing embodiments.
In the figure, A is a self-sustaining type disposable package container according to the present invention. This package container A is provided with an outwardly projecting annular flange portion 10 at the upper end and a circular horizontal bottom wall 11 at the lower end thereof. A large number of strip-shaped side walls 12 are provided between the flange 10 and the bottom wall 11 to connect them.

The strip-shaped side walls 12 are each twisted outward through the space 13, and the annular flange 10 is formed.
And the bottom wall 11 are arranged in a curved inclined shape, and the large number of these strip-shaped side walls 12 vertically hold the annular flange portion 10 and the bottom wall 11 apart from each other, so that the package container A has a self-sustaining shape. It is provided.

In the figure, B is a single sheet material constituting this self-supporting type package container A. In this example, the single sheet material B is made of medium-thick paper so that it is suitable as a disposable article. A circular one having a diameter of 125 mm was used.

The single sheet material B has a continuously integrated outer peripheral edge portion 10a having a width of 8 mm and a circular in-plane base portion 11a having a radius of 23 mm from the center at the central position,
By forming a large number of cuts 12a between the inner end of the outer peripheral edge 10a and the outer end of the in-plane base 11a, a curved radial shape divided by the cuts 13a is formed to have 18 connecting strips 12a. At least

The notch 13a of the present embodiment is formed by the in-plane base portion 11
From the intersection of each angle 20 ° line passing through the center of a and the outer end of the in-plane base 11a to the intersection of each separation line of the same angle 130 ° passing through the center and the inner edge of the outer peripheral edge 10a, The notch 13a is arranged so as to be located on an arc locus having a diameter (46 mm) of the in-plane base 11a as a radius, with the opposite outer end positions on the opposite side of 180 ° of the inner base 11a as centers. It is arranged at the inner end of the outer peripheral edge portion 10a and the outer end of the in-plane base portion 11a in a curved radial pattern at an angle of 20 °.

As a result, each connecting base portion 12a is connected to the inner edge of the outer peripheral edge portion 10a and the outer edge of the in-plane base portion 11a by the angle width of 20 °, and the in-plane base portion 11a to the outer peripheral edge portion 10a.
It is formed so as to have a tapered shape in the a direction and has the above-mentioned curved radial shape.

In order to use this single sheet material B as the package container, the single sheet material B is so arranged that the outer peripheral edge portion 10a is pivotally displaced upward and laterally with respect to the in-plane base portion 11a.
By making the outer peripheral edge portion 10a into the annular flange portion 10, the in-plane base portion 11a into the bottom wall 11, and the connecting strip portion 12a into the strip-shaped side wall 12.

The spiral deformation may be carried out by fixing one of the outer peripheral edge portion 10a and the in-plane base portion 11a and applying a rotational external force to the other. At this time, the belt-shaped side wall 12a is connected to the outer peripheral edge portion 10a and the surface portion. It suffices to bend the inner base portion 11a so as to have the above-mentioned twisted shape and to give a crease.

Therefore, the spiral deformation can be performed mechanically, for example, by clamping with a molding means such as press molding under heating or vacuum molding, and at the same time, at room temperature, the same molding as described above is performed. Or can be done manually.

The above-mentioned press molding can be carried out by a conventional method except that a male mold which operates stepwise so as to achieve molding can be carried out by pressing down the rear in-plane base 11a with the outer peripheral edge 10a being pinched, Further, the vacuum forming can be performed by using a plug-assist type, for example, in which the single sheet material B is pressed down to a predetermined depth by a plug that is loosely fitted into the female mold and sucked toward the female mold side. it can. At this time, if the single sheet material B is preheated or a heating die is used, the belt-shaped side wall 12 can be bent or twisted favorably at the time of spiral deformation, and the folding tendency can be more surely maintained. It is possible to reinforce the sex.

FIG. 3 shows a purchasing unit figure using this package container A. In this example, the package container A is used.
For the product, put a certain number of piece-shaped products 20 in which various fruit sauces such as plums and oranges are filled in a small container so that the back side of them does not come out to the front side, and then wrap the whole with a transparent outer bag 30. It is packaged in.

Therefore, the appearance is better than that simply packed, and the product value is enhanced and the willingness to purchase is increased, and the buyer removes the exterior 30 and the package container A.
As it is, it can be stored, and if necessary, it can be used as a table or the like in the package container A for consumption according to taste, and after consumption, as it is, or the bottom wall 11 It may be pushed up, returned to the original single sheet material B, and discarded.

In the figure, 14 is a corrugated line for forming irregularities provided to reinforce the annular collar part 10 and to improve the design, and 15 is a fold line between the annular side wall part 12 and the annular collar part 10 or the bottom wall 11. Is.

Although the explanation is given according to the example shown in the drawings, in the present invention, the single sheet material is replaced by the thick paper or the synthetic paper instead of the medium thick paper, and the PE is used as the paper base.
It is also possible to use a laminated sheet in which T, styrene resin, metal foil, etc. are laminated, or a synthetic resin sheet material such as styrene resin can be used. At this time, the single sheet material may be flexible or somewhat soft as long as it can withstand spiral deformation including bending of the strip-shaped side wall as shown in the above example. Good. On the other hand, since the present invention is of a disposable type, it is not appropriate to use expensive thermosetting resin, metal plate or the like.

It is necessary that the outer peripheral edge of the single sheet material has a uniform distance from the in-plane base and is integrally formed without being cut in the outer peripheral direction. As long as this condition is satisfied, the shape of the base can be appropriately determined along with the shape of the inner end of the outer peripheral edge, such as an ellipse.

The cuts for partitioning the connecting strips may be curved radial lines other than the above, such as an elliptical locus or a plane spiral locus, or, for example, an equally inclined radial line formed by straight lines at equal intervals from the in-plane base. It can also be

It is also possible to use slits or other cut grooves instead of the cuts, or to use the cuts and cut grooves together or to change the cut groove width depending on the part.

In the spiral deformation, when heating or molding at room temperature, the strip-shaped side wall can be made to conform to the curved surface without twisting it outwardly.
In this case, it is not necessary to install a stepped portion corresponding to the twist in the female mold or the male mold, and it is possible to simplify the mold manufacturing.

When the single sheet material is deformed in a threaded manner, a heat-curable resin sheet, a resin liquid agent or the like is added to the corresponding portion forming the band-shaped side wall bent portion on the front surface, the back surface, or both. It is possible to perform a screw-like deformation fixing process by heat-molding or by partially heating and pressurizing the material after it has been adhered and coated. In this case, it is possible to improve the self-sustaining shape retention property of the package container by making the creases more reliable or fixed, and it is possible to take only partial measures. This is suitable when using a material that is difficult to secure its shape retention.

The self-supporting disposable packaging package of the present invention generally requires further packaging for sealing when the piece-shaped product is a food product including, for example, candy and confectionery. In addition to the outer bag, the outer bag may be shrunk, or the outer bag and the shrimp may be packaged in the same manner with a lid or a surface label.

When the piece-shaped product is sold individually, such as an office eraser, it is possible to remove the package from the package container and use it as a product for store display.

As will be apparent to those skilled in the art from the above description,
In carrying out the present invention, a single sheet material, its outer peripheral edge portion, in-plane base portion, notch, kerf, connecting band portion, spiral deformation,
The material, shape, forming means, size, reinforcing means, and addition of the annular collar portion, the bottom wall, and the belt-like side wall, and the use as a package container, etc., are appropriately provided on the condition that they do not violate the gist of the invention. It can be modified and need not be limited to what has been illustrated and described above.

[0029]

Since the present invention is constructed as described above,
By providing a predetermined cut or cut groove on a single flat sheet material and spirally deforming this,
It is possible to obtain a low-cost self-supporting disposable package container that is self-supporting.

Further, since this package container can have a self-supporting shape and an excellent design appearance,
It is useful for increasing the product value of various piece-shaped products including foods and for increasing the willingness to purchase, and for storing these piece-shaped products in package containers, which is suitable for table consumption and individual sale. Therefore, it can be used not only at the distribution stage but also at the consumption stage.

Further, since the single sheet material can be made of an inexpensive material such as paper or synthetic resin, it can be made into a disposable package container which does not give a consumer a feeling of resistance.
