JP3056126U - Container with bent plate edge - Google Patents

Abstract

(57) [Problem] To obtain a circular or oval container having a bent plate edge. A bent plate edge (1) obtained by bending an elongated plate having a thickness of 2 mm or more into a circular or elliptical shape by a bending roll machine.
A bent-plate-edged container, in which one or both of the both ends of the joint (3) are scraped off and glued or stapled to form a box edge.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a souvenir container and a container with a bent plate used as an alternative to a high-quality folded box.

[0002]

[Prior art]

 Conventionally, various types of containers having circularly bent edges have been used.One of them is a thin plate made of cedar, cypress, etc., which has been softened by high-temperature steaming or boiling, wound around a cylinder and bent. A crafted high-grade product called a bent product, in which seams are carefully sewn together, is known, but it has a different taste from the container for storing souvenirs, etc., which is the purpose of the present invention.

[0003] Furthermore, a thin plate having a thickness of about 1 mm is bent into a circular shape, and a round bottom is fitted and glued, or another bottom receiving bar is attached to the inner periphery of the lower end to support a bottom plate. Inexpensive products have been widely used for lunch boxes and the like.

In addition, a large number of longitudinally cut grooves are formed at appropriate intervals over the entire length of the inner surface of a thick plate having a thickness of about 3 mm, and are bent by the cut grooves to form a substantially circular or elliptical shape. Or a plastic foam board bent into a circular shape.

[0005]

[Problems to be solved by the invention]

 The above-mentioned high-end products called bent products are expensive because they cannot be mass-produced, and are unsuitable for use as containers for general products.

[0006] Furthermore, a thin plate having a thickness of about 1 mm can be easily manufactured because it can be easily bent, so that a bending process by a bending roll machine is unnecessary. However, since the edge material is thin, it is easily broken. However, since it is inferior in value as a container, it is often used for lunches which are disposable in a short time, but there is a problem that strength is insufficient for general products.

[0007] A thick plate having a thickness of about 3 mm with a large number of cut grooves on the inner surface side requires a lot of trouble in manufacturing and has a problem that the product value is inferior due to polygonal bending. there were.

[0008] Thick plastic foam boards are flexible and do not require bending using a bending roll machine, so they can be easily manufactured. However, they cannot be denied a substitute feel compared to wooden boards. However, it has a problem that it is not suitable as a container for confectionery or the like that needs to be stored for several days because it has a low product value and has a difficulty in breathability as compared with a wooden one.

[0009]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention is based on the idea that a long or thin plate having a thickness of 2 mm or more is bent into a circular or elliptical shape by a bending roll machine, and both ends are overlapped and joined. It has the authentic feel of wood and the sense of stability due to its thickness.

[0010]

[Embodiment of the invention]

 In the present invention, a bottom fitting groove along one side is formed in a long and thin plate having a thickness of 2 mm or more, and a joint formed by shaving one end or both ends is formed by a bending roll machine. The bottom of the bent plate edge curved into a circular or elliptical shape with the fitting groove side as the inner circumference, the bottom is fitted into the bottom fitting groove, and the above-mentioned joints at both ends are overlapped and glued or stapled. It is.

[0011]

【Example】

 The embodiment will be described with reference to the drawings. FIG. 1 is a perspective view showing an example of a container with a bent plate edge according to the present invention, and FIG. 2 is a longitudinal section of FIG.

In the drawing, reference numeral 1 denotes a bent plate edge, and a bottom fitting groove 2 along one side surface is formed at a depth of 1/2 to 2/3 of the plate thickness in a plate material having a predetermined width and length having a thickness of 2 to 3 mm. Then, as shown in FIG. 3, a bending roll machine 5 composed of three rolls is used to form a joint portion 3 by diagonally shaving off both ends, one of which is an inner surface side and the other is an outer surface side which is cut off obliquely. It is curved in a circular shape with the bottom fitting groove 2 side as the inner circumference.

Thus, an appropriate amount of an adhesive such as hot melt or cyanoacrylate is applied to one joining portion 3 of the bent plate edge 1 which is curved in a substantially circular shape, and a circular thin plate or After fitting the bottom 4 made of cardboard or the like, the joining portions 3 at both ends are overlapped and bonded.

In the figure, the joining portion 3 is shown with the both surfaces cut off diagonally. However, there are cases where the plate thickness is cut in parallel, and cases where only one surface is cut. In some cases, stapling may be performed instead of bonding.

In the case of an elliptical container, the control can be performed by changing the roll position of the bending roll machine 5 shown in FIG. 3 in the middle of the bending process.

[0016]

[Effect of the invention]

 The present invention is embodied in the form described above and has the following effects.

Since a plate having a thickness of 2 mm or more is manufactured by bending the plate, the strength is large, breakage due to an external force during transportation or the like can be prevented, and damage to stored items can be prevented.

Since the bent plate edge is made of wood, the container itself has air permeability and hygroscopicity, and has excellent storage stability.

The attractiveness of the natural products of wood and the gorgeous feeling of the slabs give the image of luxury goods and increase the commercial value of the contents.

Since most of the manufacturing steps are mechanized, the cost can be reduced by mass production.
