Abstract

To provide a molding sheet capable of shape change by any pressure by human hands such as crushing with rolling, twisting with grabbing, or pinching a part, and easily being returned to original flat sheet shape and being repeatedly used.SOLUTION: The molding sheet can maintain shape change by any pressure by human hands such as crushing with rolling, twisting with grabbing, or pinching a part and easily is returned to an original flat sheet shape, since it has deformation property of an aluminum foil and flexibility of a fiber raw material by laminating the aluminum and the fiber raw material.SELECTED DRAWING: Figure 1

Description

The present invention relates to a lithographic sheet in which a plurality of aluminum foils and fiber materials are laminated, and relates to a shaped sheet capable of reversibly maintaining a deformed state and restoring the lithographic sheet.

Various planographic sheets in which aluminum and a fiber material are laminated have been proposed. Conventional aluminum laminated sheets functioned and focused on heat insulation and heat retention.

Aluminum foil can maintain its deformed state when it is rolled and crushed by human hands to change its shape. However, on the other hand, it is difficult to return to the original sheet shape because the aluminum foil that has been rolled and crushed is torn from the fold when it is spread.

It is difficult to maintain the shape of general fibrous materials, such as cloth, because they tend to rebound and spread when attempting to change the shape, such as rolling and crushing with human hands. However, it is easy to spread to the original lithographic shape.

From the above two points, if aluminum foil and a fibrous material such as cloth are laminated, it should be possible to repeat the change in shape, such as rolling and crushing by hand, and expanding it back to a flat sheet. .

However, conventional laminated sheets made of aluminum and fibrous materials were made with a focus on heat retention and heat insulation, and their use as molding materials was not considered.

Origami is generally used as an existing modeling sheet.However, since origami is basically formed by making folds in a straight line, people who roll, crush, grasp, twist, or pinch a part It is not suitable for free repetition of molding at any pressure by hand.

The shaped sheet of the present invention is a sheet material in which a fibrous material such as aluminum foil and cloth is laminated, and retains a shape change under arbitrary pressure by a human hand, such as rolling, crushing, grasping, and twisting. It is also possible to return to the original flat sheet shape at the same time, and it can be repeatedly used as a sheet-like molding material having reversible plasticity.

Since the shaped sheet of the present invention is a sheet material having reversible plasticity, it is possible to provide a shaped sheet that can be repeatedly held in a deformed state such as being rolled and crushed by a human hand and returned to the original planographic sheet. .

Since the shaped sheet of the present invention can maintain a deformed state due to external pressure, a shaped sheet capable of three-dimensional shaping having a twisted surface such as rolling, crushing, grasping, twisting, or pinching a part by a human hand. Can be provided.

One of the uses of the present invention is its usefulness as a packaging material. The present invention is rich in cushioning properties due to the laminated structure of the fiber material. In addition, since there is a property of retaining the deformed shape, the contents can be protected while wrapping the object without using an auxiliary material such as an adhesive tape. It can be used as a packaging material that can be used repeatedly.

The photograph which shows the example of use of the shaping sheet which concerns on this invention. Fig. 4 is a photograph showing a molding example of the molding sheet according to the present invention. Fig. 4 is a photograph showing a molding example of the molding sheet according to the present invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The same numbers in each figure indicate the same contents. The embodiment of the present invention is not limited to the present embodiment.

The modeling sheet is composed of a laminate of fibrous materials such as aluminum foil and cloth. FIG. 1 is a sectional view of an embodiment of the present invention.

In FIG. 1, reference numeral 1 denotes a fiber material serving as a base material of the shaped sheet of the present invention. In the example, 1 was a polyester non-woven fabric. 2 is a metal foil. In the example, 2 was aluminum foil. 3 is a fiber material for protecting the surface of aluminum and adding strength to the sheet. In the examples, a plain woven cloth made of polyester was used in combination.

FIG. 2 is a photograph of an example of a molded sheet. FIG. 2A shows a basic square, and FIG. 2B shows an added design. By making the plane shape a square, it is also possible to make a shape by folding the same shape as origami. In addition, by maintaining the deformed state, which is a feature of the present invention, arrangements such as twisting and bending can be added to the origami-like modeling.

The shaped sheet of the present invention may have a planar shape other than a polygon having sides formed by straight lines. By changing the planar shape to various shapes, the possibility of modeling and manufacturing is expanded.

FIG. 3 is a photograph showing a deformed state of the present invention. FIG. 3A shows a state in which the example is grasped. FIG. 3B shows a state in which the embodiment retains the deformed shape. FIG. 3 (c) shows a slightly expanded embodiment of FIG. 3 (b). FIG. 3D shows a state in which the embodiment is returned to a planographic shape. Thus, the shaped sheet of the present invention can reversibly maintain a change in shape.

FIG. 4 is a photograph showing a deformed state of the present invention. FIG. 4 (a) and FIG. 4 (b) also show how the shaped sheet of the embodiment is folded and twisted. Thus, the present invention can easily change the shape by the pressure of human hands.

FIG. 5 is a photograph showing usefulness as a packing material, which is one of the uses of the present invention. FIG. 5 (a) shows one raw egg, and FIG. 5 (b) shows two raw eggs held by one shaped sheet of the embodiment so as not to roll. INDUSTRIAL APPLICABILITY The present invention is rich in cushioning properties because the fiber material is laminated, and is suitable for packing fragile items such as raw eggs. In addition, since the aluminum foil has the property of retaining the deformed shape, the contents can be held without wrapping materials such as an adhesive tape.

FIG. 6 shows an example using the shaped sheet of the present invention. The example is a container manufactured by picking the modeling sheet of the example with a finger and adding a twist. When doing the same with origami, it is difficult to maintain the shape with soft paper, so auxiliary materials such as adhesives are required, and with hard paper, it is difficult to bend while curving with curved folds, so it is difficult . In that regard, the present invention can be said to be a molded sheet that can be easily formed by anyone.

FIG. 7 shows an example using the shaped sheet of the present invention. FIG. 7 (a) shows a model of a cat manufactured using the model forming sheet of the embodiment. FIG. 7 (b) shows a dog model made with the model sheet of the embodiment. FIG. 7 (c) shows a model of a rose manufactured using the model sheet of the embodiment. When fabricating such a complicated shape with a cloth, auxiliary materials for maintaining the shape, such as sewn or stuffing cotton, are required. However, the shaped sheet of the present invention can maintain the shape by itself.

The same modeling as in the examples from Fig. 3 to Fig. 7 is possible with aluminum foil alone, but with aluminum foil, once shaped, it is almost impossible to return to the original planographic plate, and if it fails, material is wasted Become. With the molding sheet of the present invention, it is possible to easily return to the original planographic plate after molding, so trial and error of molding is possible, and it can be used over and over again, so you can produce molding without worrying about failure can do.
