Abstract

Shoe with slipper function both open and closed, of the type realised by means of perimetrical sewing ( 3 ) of the upper ( 2 ) on the sole ( 1 ), having the following characteristic: I-use of an elastically yielding flexible expanded plastic material sheet with alternatively variable thickness >2 mm and <8 mm, pierced (F) and bossed on its surface (e) and ribbed (i) on the opposite surface, the piercings being made in the thinness zones and then alternated by bossings (e); II-punching of said sheet in soles ( 1 ) and uppers ( 2 ); III-perimetrical sewing at the sole edge ( 3 ) of the upper ( 2 ) to the sole ( 1 ); IV-with the characteristic that said bossings (c) are placed towards the outside of the shoe both for the sole ( 1 ), thus toward the, floor, and for the upper, thus towards outside.

Description

The present invention relates to a shoe according to the preamble of the main claim.
Although the intended use is for footwear, it is not limited to just for home use.

In the current state of the art, for example footwear for home use, for example, an open rear slipper and a full-foot slipper, for example, are known. For home use and for hotel bedrooms.

However, this does not exclude applications in environments with a smooth and comfortable floor, such as in a swimming pool.
These shoes or slippers (the slippers in this specification mean not only the rear open ones, but also the rear closed ones such as the shoes that cover the entire foot) are easy to put on and sweat away. In general, it is made of cloth.

Disadvantages Conventional types of slippers solve these problems, but are expensive and have limited uses. For example, those made of cloth cannot be used in a swimming pool or the like.

The purpose of the present invention is not only to realize an inexpensive slipper, but also a comfortable and breathable, lightweight, non-slip and antibacterial (bacteria are liable to inhabit textiles and fabrics) Is to realize.
That problem is solved by the features of the main claim. The dependent claims also represent preferred solutions.

Advantages This method provides the following advantages.
-Quality and low price that can be adapted to the application.
-Breathability through multiple perforations on both the bottom and outsole.
Antiperspirant due to the presence of light internal reliefs (resulting from polyester net folds) that prevent complete contact with the skin.
-Flexibility and softness due to the porosity of the foam plastic material.
-Durability due to foamed polyvinyl chloride material used for polyester nets.
-Anti-slip with external protrusions spread on the bottom of the shoe sole.
Antibacterial properties due to material type and antibacterial treatment.
-Heat resistance up to 80 ° C depending on the type of material used.
・ Environmentally friendly due to non-polluting materials.
-Elasticity due to the porosity of the material.

DETAILED DESCRIPTION OF EMBODIMENTS The present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 shows a perspective view of a rear open slipper.
FIG. 1A represents a cross-sectional view in an enlarged cross-section of a single material that constitutes a slipper, showing that there is no difference between the bottom and the upper when the bottom and the upper are stitched to form the slipper.

Detailed Description of the Figures A single with a polyester net, as seen in the figure representing an open slipper at the rear (but it is also obviously possible to close the rear to house the heel) PVC foam sheet material is used, holes (F) are drilled, protrusions (e) are created on one surface, and undulations (i) are formed on the back surface (FIG. 1A). The base material is perforated foamed flexible material, non-tissues with protrusions.

By known techniques, the sheet is cut into the shape of the bottom (1) and the shape of the outsole (2), the upper (2) is sewn to the bottom (1) (3), Care is taken that the surface with the protrusions is arranged on the outside, and therefore on the lower side of the bottom (1) and the upper side of the upper (2).
According to this method, in a very simple and cheap form, as a result, as described above, the upper (2) and the bottom (1) are provided with perforations (F), thereby having complete breathability. Slippers that are not slippery are obtained.

The peripheral seam (3) extends beyond the upper (2) to all edges of the bottom (1). According to this method, the greater strength and durability of the slipper can be obtained.
Sewing is also conveniently carried out along the free end (21) of the upper. According to this method, even greater durability is imparted to the slipper, avoiding the material from expanding by being pressed against the instep.

  Conveniently, a single tissue is applied to cover the top or bottom of the edge or the edge to be joined or the single edge to be reinforced before perimeter sewing. This method has the advantage of being strengthened. This method has the advantage that the slippers are rounded and reinforced by a thin frame around each seam (the solution is not shown but is clearly intuitive and can be understood by those skilled in the art) It is known, but it enhances the edges and sewing of non-woven materials that are flexible and flexible).

The material is conveniently surface treated by known mold prevention techniques.
The following parameters are applied to obtain the desired material cross section. The thickness is selectively variable and is greater than 2 mm and less than 8 mm. A maximum thickness of 5-6 mm is convenient.

FIG. 1 shows a perspective view of a rear open slipper. FIG. 1A represents a cross-sectional view in an enlarged cross-section of a single material that constitutes the slipper, showing that there is no difference between the bottom and the upper when the bottom and upper are stitched to form the slipper.
