  Hereinafter, the present invention will be specifically described based on illustrated embodiments. This simple slipper S is roughly composed of a slipper base 1 and an upper cover 2. This slipper base 1 is configured by combining base plate elements 10 using corrugated cardboard materials. In the embodiment shown in FIGS. 1 to 3, an upper base plate element 11, a lower base plate element 12 and The two base plate elements 10 are configured. Specifically, the upper base plate element 11 and the lower base plate element 12 have substantially the same planar shape, and each of the corrugated cardboard materials has a liner L on one side of the corrugated cross-section flute F. A single-sided corrugated cardboard is used. Each of the upper base plate element 11 and the lower base plate element 12 forms a cut at a position where the upper cover 2 is fixed, and the portion is used as a fixed portion display 11a of the upper cover 2. .

Note that the upper base plate element 11 and the lower base plate element 12 are formed by punching from corrugated base paper, and it is preferable to form a cut as the fixed portion display 11a in the process. Needless to say, the fixed portion display 11a may be not incised but indented in an embossed shape.
For punching formation, a general punching machine is used. However, the punching blade itself is not a so-called flat blade, but a blade having a wavy or saw blade shape. As a result, as shown in an enlarged view in FIG. 2 (c), the cut end edge 10E is formed in a zigzag shape, which is preferable in that the portion is not sharp and safety is increased.
Furthermore, when this punching is performed, a sponge-like elastic member is arranged in a strip shape on both sides of the punching blade, while this elastic member slightly crushes the edge of the flute F, while the return elasticity helps to pull out the punching blade. Contributes to smooth punching.
Furthermore, in particular, on the upper surface (tread surface) of the upper base plate element 11, a crush-like point pressure improving structure 11b is formed at a constant interval on the top of the uneven flute F.

  Next, a bonding form of the upper base plate element 11 and the lower base plate element 12 will be described. In this bonding, the directions of the liner L and the flute F of the corrugated cardboard material are set so that the flute surfaces face up and down. As a result, the liners L of the corrugated cardboard material are as if they are back to back. It is fixed. In this embodiment, the wavy direction of the flute F of the upper base plate element 11 is formed along the width direction of the slipper base 1, while the wavy direction of the flute F of the lower base plate element 12 extends in the longitudinal direction, resulting in In addition, the wavy directions of the flutes F of the upper base plate element 11 and the lower base plate element 12 are substantially orthogonal to each other. Of course, this intersection angle is not limited to orthogonal, and is shown in FIG. As described above, the flute F of the upper base plate element 11 can be configured so as to follow the inclination because the thumb side, which is the shape of a human toe, has the longest foot length and the short little finger side. . Accordingly, the flutes F of the upper base plate element 11 and the lower base plate element 12 are combined in a crossing manner as defined in the claims.

Next, the upper cover 2 will be described. The upper cover 2 is provided in front of the center of the slipper base 1 in the longitudinal direction. As the material, for example, kraft paper is used as a raw material, and a material obtained by creping the material is used, and the material is cut into a strip shape.
Since the upper cover 2 is required to have the simple slipper S attached to the tip of the foot, the strip-shaped upper cover 2 is naturally stretchable in the creping direction so that it can be expanded and contracted in the longitudinal direction. Is provided in a direction orthogonal to the longitudinal direction of the upper cover 2. In addition, the upper cover 2 has a portion 21 that is exposed upward from the slipper base 1 and supports the upper portion of the foot from above, and the both ends thereof are fixed portions 22. The fixing portion 22 is inserted into the upper base plate element 11 and the lower base plate element 12 with the fixing portion display 11a or 12a as a mark, and the upper base plate element 11 and the lower base plate are bonded with adhesive or the like on both upper and lower sides. It is fixed so as to be sandwiched between the elements 12.

The present invention has a configuration as described above, and in order to use this, a foot tip is inserted between the slipper base 1 and the upper cover 2 in the same manner as a normal slipper. Use.
At this time, when the upper cover 2 is made of a strip-shaped crepe paper, it is somewhat stretchable, so that the foot slipping effect is sufficiently exerted, and the simple slipper S is provided at the toe portion. Can be worn in a very natural fit.
The load applied to the slipper base 1 is appropriately deformed or crushed by the corrugated cardboard flute F of the base plate element 10 to absorb the soft comfort and the acupressure effect on the sole of the foot, and the unevenness of the floor surface. Demonstrate the buffer effect.

  In addition, when moving with the simple slipper S, the lower base plate element 12 is configured such that the wavy direction of the flute F is formed in the longitudinal direction as an example, and there is resistance to bending in that direction, Since the upper base plate element 11 has the wavy direction of the flute F configured in a direction orthogonal to the longitudinal direction of the slipper base 1, the slipper base 1 is naturally bent near the toe portion during walking. Combined with the action of both, moderate rigidity and flexibility when worn can be obtained.
