A sponge made of luffa

Abstract

The sponge made of two layers, formed by the walls of the fine-fibered luffa fruit is offered. Each layer is at least a part of the wall of the luffa fruit with the adjacent radial jugums. One layer with the side of the outer part of the fruit wall is adjacent to the side of the radial jugums of another layer. The layers are connected along the perimeter by a sewing seam. The making of one layer of the sponge with a steady active surface, consisting of structure-forming and reinforcing fibers of the radial jugums and the inner part of the wall of the luffa fruit reduces its wear and increases its service life while preserving its elasticity.

Description

A SPONGE MADE OF LUFFA TECHNICAL FIELD OF THE INVENTION

[0001] The invention relates to household items, in particular to sponges made of plant materials,in particular of luffa, intended for washing, cleansing and massaging human skin.BACKGROUND OF THE INVENTION

[0002] The closest to the offered sponge is a sponge (USA patent No.: US 10,485,387 B2, Nov.26, 2019). The sponge contains a working member made of two layers, manufactured from afine- Luffa cylindrica Roem" species. Each working member layer is at leasta part of the wall of the luffa fruit with the adjacent radial jugums. The working member layersother from the side of the radial jugums, framedand connected along the pe ,. Wherei hanging fixed at one end.

[0003] The disadvantage of the known sponge is the absence of a stable ability of the layers ofthe working member to provide the ability to wash, cleanse and massage human skin inaccordance with its need for enhanced washing, cleansing and massage effects. Thisdisadvantage is explained as follows.

[0004] The active surface of the layers of the working member is the outer part of the wall ofthe fine-fibred luffa fruit (agrolib.ru / rastenievodstvo / item / f00 / s01 / e0001140 / index.shtml).

[0005] The outer wall of the fine-fibred luffa fruit consists of tender and fine fibers that form asurface with a homogeneous roughness. The impact on the skin of the active surface of the layersof the working member, which is a surface with a homogeneous roughness of tender and thinfibers, causes a gentle washing, exfoliation of dead skin cells and massage effect.

[0006] The impact on the skin of the framing the edges of the workingmember causes a delicate washing, cleansing and massage effect. SUMMARY OF THE INVENTION

[0007] The object of the invention is the development of a sponge made of luffa, having theability to wash, cleanse and massage human skin in accordance with its need for enhanced washing, cleansing and massage effects, having reliability, safety for the user, convenience in anindustrial manufacture by means of the design solutions and the maximum use of the luffa properties, namely a stable ability of the working member to perform the functions, the comfortduring use, the absence of the contamination after use, increased service life, with both parts ofthe working member made of luffa, which can be manufactured simple and rapidly.

[0008] The object set has been solved in the following way.

[0009] The sponge contains a working member made of two layers manufactured from fine-fibred luffa. Each layer of the working member represents at least part of the wall of the luffafruit with adjacent radial jugums. One layer with the side of the outer part of the fruit wall is adjacent to the side of the radial jugums of another layer. The layers of the working member are connected along the perimeter by a sewing seam.

[0010] The invention uses a fine-fibred luffa of the "Luffa cylindrica Roem" species(agrolib.ru / rastenievodstvo / item / f00 / s01 / e0001140 / index.shtml). The outer part of the luffa fruitwall is a net of tender and thin fibers. The inner part of the wall and the radial jugums of the fruitare a network of tightly intertwined, but not adjacent to each other, structure-forming and fruit- reinforcing fibers, which determines a spatial net structure from individual fibers.

[0011] -forming and fruit- The continuity of fiber connections at the junction of the radial jugums with the inner part of the fruitwall determines the stability of the structural formation of the fruit wall and the radial jugums.

[0012] capillarity.

[0013] The active surface of one layer of the working member of the invention is the inner partof the wall of the luffa fruit with radial jugums. This solution makes it possible to create a stable ability of this layer of the working member to provide enhanced washing, cleansing and massage effects and is explained as follows.

[0014] The high porosity and capillarity of the fibers of the radial jugums and the inner part ofthe fruit wall cause a significant increase in the volume of the fibers when using a sponge, allow for to rapid absorption and return of water and in combination with the spatial net structure ofthe luffa fruit wall lead to high elasticity of the layer of the working member. This leads to thefact that during intense friction between the active surface of this layer of the working memberand the user’s skin, the structure-forming and fruit-reinforcing fibers of the radial jugums andthe inner part of the fruit wall, thanks to its high elasticity and the stability of the structuralformation of the fruit wall and the radial jugums, and of fiber connections at the junction of the radial jugums with the inner part of the fruit wall, retain the original structure of their formationand connections and create the steadiness of the protrusions of the radial jugums and the surfaceof the inner part of the fruit wall during use. The impact on the skin of the active surface of thelayer of the working member, which is a surface with a steady heterogeneous roughness of the structure-forming and fruit-reinforcing fibers of the protrusions of the radial jugums and the inner part of the fruit wall, leads to intensive exfoliation of the dead skin cells, deep cleansing of the pores, forceful massage and lymphatic drainage effect, which causes enhanced washing,cleansing and massage effects. This leads to the stable ability of this layer of the working memberto provide the ability to wash, cleanse and massage human skin in accordance with its need for enhanced washing, cleansing and massage effects.

[0015] The active surface of the other layer of the working member is the outer part of the wallof the fine-fibred luffa fruit. This creates on the side of this layer of the working member a surface with a homogeneous roughness of tender and fine fibers, which causes a delicate washing effect, exfoliation of dead skin cells and massage.

[0016] The reliability of the sponge is determined by the stability of the structure of the fruit wall andradial jugums, which is created by the continuity of the interweaving of structure-forming and fruit-reinforcing fibers throughout the entire area of adjacent of the radial jugums to the inner part of the fruitwall.

[0017] and capillarity,es the and the space between the working the contamination of

[0018] shape, including with the presence of loop- with a loopsponge, ensures the possibility of washing, cleansing and massaging the hu skin in accordance withhis anthropometric peculiarities and creates comfortable conditions for the user when using the product.

[0019] The structure of the fruit wall and radial jugums, characterized by the possibility of compression,

[0020] along the perimeter with a sewing seam leads tothe possibility of the fullest use of the entire surface area of each layer. Connecting the layers of theworking with a sewing seam along part of the entire length of the perimeter provides direct access to washing the space between the layers of the working to remove contaminants after use, which increases the safety of the sponge for the health of the user.
