Description

The technical field to which the utility model relates.

The presented utility model relates to diapers for children and adults, and more particularly to reusable liners in diapers.

State of the art

Currently, the most widely used disposable diapers, which are lightweight to use for guardians, but have a number of significant drawbacks. Among the economic disadvantages is, first of all, a significant burden on the budget associated with one-time use, which results in a large number of consumed products. There are also hygienic factors that limit the use due to the health of the carrier due to the harmful chemicals that make up the active absorbents, as well as due to low air permeability, which causes an unfavorable, overheated and overheated microclimate in the inner space of the diaper, which closes the lumbar-genital area of the user. There is also a real risk of infection of the urogenital system of the carrier due to the practice of wearing a dangerously contaminated diaper after the first bowel movement, since the danger is mixed with a fairly comfortable sensation of the user. A significant drawback of disposable diapers is the huge amount of difficult to recycle heavily contaminated and infectious hazardous waste, which is a serious social and environmental problem.

The use of reusable diapers is somewhat more troublesome for carers, but allows you to eliminate or mitigate the above social, economic and environmental problems. In addition, the use of reusable diapers is a socially responsible behavior of people and, as such, is gaining more and more supporters.

There is another significant side to the issue. Until now, little attention has been paid to the problem of teaching self-regulation of the wearer of diapers, especially a newborn, in whom it is necessary to form skills to contain natural needs from scratch. And this requires feedback in the form of discomfort during spontaneous administration of the body. That is, the diaper should get wet and naturally cool, and due to this create a learning feeling of discomfort in the wearer. In this case, the diaper should not get wet and leak, contaminating things in the neighborhood. However, almost all disposable diapers, as well as most sealed reusable diapers with a waterproof layer, eliminate discomfort and, therefore, feedback, thereby depriving the user of relevant information. This leads to such widespread problems in our era as difficulties in teaching a child to use a pot, inability to restrain natural functions, enuresis, etc. One more negative aspect can be noted - the formation of a newborn's incorrect perception of clothing as a latrine and fixing wrong habits. The child gets used to perceive clothes as a pot. And with subsequent training in using the potty, the child simply does not understand what they want from him, since he has already been taught a comfortable bowel movement in clothes. Before the era of disposable diapers, the problem was solved by itself - soaking traditional diapers and diapers gave reliable feedback.

At present, diapers without waterproof layers can solve the problem of feedback through discomfort. For example, diaper panties are known as described in patent RU 2400200 [1]. However, when using them, it is quite difficult to strike a balance between getting wet and leaking if you use well-known liner devices, which leads to unpleasant cases of excessive getting wet and dirty clothes and other things.

A common solution to increase the absorbent capacity of the diaper is to use liners. The use of additional liners in reusable diapers is convenient for users, as significantly increases the absorbent capacity, and also allows you to separate the most severe impurities and collect them on a simpler in design and more simply cleaned separate liner of the external diaper. In addition, in the case of slight contamination of the liner, you can only replace the soiled liner with a clean liner without changing the diaper itself, which also saves the efforts of the guardians.

One of the most famous diaper liner options in Russian practice is traditional diaper liners made of multilayer cotton gauze in the form of squares, rectangles or triangles. Gauze is a very comfortable and breathable, cheap and affordable material for liners in diaper panties. Being a sparse tissue, gauze in a folded form creates a cellular or cellular structure, which absorbs both liquid and suspended waste products very well. Traditional gauze multilayer square liners are usually folded twice or triple into an oblong rectangle before use and placed inside the diaper panties. After use, the gauze liner is easy to rinse, wash and iron, as it unfolds into a thinner and less multi-layer plane. However, such diaper liners also have disadvantages. Double or triple folding of gauze from the edges forms an excess thickened layer of material. Located under the back of the wearer, such a thickening is unpleasantly felt by the user and leads to skin nosing. It should be noted that the intense stream during urination into such an insert does not have time to break into a rarefied material and disperse in its area and volume, which can lead to local leakage. We add that such an insert is not optimal in design, because does not allow easy and convenient redistribution of material from less functionally loaded places to those places where a large absorbent capacity is required.

Other absorbent materials are used to make absorbent liners in diapers. Cotton materials such as muslin, chintz, flannel, etc. are common. Various natural, artificial and synthetic materials can also be used, including materials with special properties such as microfiber and the like. Recently, attention has increased to reusable hygroscopic hygiene products and materials for their manufacture, as can be seen from the activity of patenting. For example, WO 2017114974 [2] proposes a textile renewable material for the manufacture of incontinence hygiene devices to which one or more antimicrobial and / or hydrophilic and / or stain removing agents are attached.

Known reusable liner in the diaper described in patent US 2014221954 [3]. The liner is elongated, configured according to the shape of the external diaper in the perineum, where it is placed. This liner is made of a multilayer absorbent material and can be elongated, folded in half and fixed with reusable fasteners, which makes it easy to wash and dry. The insert can be re-attached both front and rear or only in front of the main diaper using buttons, including can be attached in two layers through holes in the intermediate layer. The insert may have an additional end pocket to accommodate additional absorbent elements.

However, the described liner itself is not provided with a barrier waterproof layer; an external diaper is provided with such a layer. That is, such an insert will not provide local protection against leakage when used in wet diapers. If you securely attach the insert to the buttons on the back, the hard and convex buttons will create tangible discomfort to the wearer when lying on its back. The end pocket of the liner is small and inconvenient; it is difficult to place and straighten additional absorbent material in it.

Closest to the claimed solution is a waterproof reusable liner in the diaper according to the patent US 2014364826 [4], configured according to the shape of the external diaper, where it is placed along the perineum. The described liner is made of a multilayer absorbent material, which is covered with a waterproof fabric on the side not adjacent to the body of the carrier. The multilayer absorbent material of the liner allows multiple restoration of its hygienic properties by washing. However, this liner design has the following disadvantages. Firstly, the liner is not attached inside the diaper and can be held in place only with pockets or cavities on the external diaper, which is unreliable and not always convenient. Secondly, the waterproof shell inseparably lining the liner from the outer plane and along its edges, which prevents both air exchange and wetting of the adjacent layers of fabric of the external diaper. And the latter is important for the formation of feedback in the wearer through a feeling of discomfort from wet tissue. Thirdly, the inseparable lining prevents the complete restoration of hygienic properties, due to the presence of dead-end zones near the waterproof fabric, such a barrier greatly complicates both washing and washing, and drying the liner. Ironing an insert of this design cannot be ironed.

The purpose of this utility model is to eliminate the disadvantages of known solutions.

The technical result of the claimed utility model is the possibility of fixing the liner inside the waterproof fabric, as well as unfastening the waterproof fabric for washing, drying and ironing the liner.

Utility Model Disclosure

Further aspects and technology features of training diapers and liners to them, given in this application, will become apparent from the detailed description presented below. In addition, any one or more aspects of the design and technology of this application can be implemented individually or in combination with any one or more other aspects of the technology of this application. It should be understood that the detailed description and examples provided therein are intended to be illustrative and should not be construed as limiting.

The present description discloses the device itself reusable liners for diapers, their use and some aspects of manufacturing. Embodiments of the present utility model may be used with diapers of various types, both disposable and reusable diapers. But first of all, the use of reusable inserts with reusable training diapers, i.e. without an external barrier layer. Accordingly, the reusable diaper liners described herein can provide numerous benefits that will be understood by those skilled in the art. Some of these advantages are described in this application.

The technical solution proposed in the utility model is a reusable insert of an elongated rectangular shape (see Fig. 1), placed in the perineal region inside the external diaper. The liner is made of a multilayer absorbent material (1) and is equipped with a waterproof sheet (2) made in the form of the liner, which is placed on the side of the external diaper. The insert has a device of the type of a pilot, that is, with a longitudinal internal cavity (3), the entrance to which is located on one of the sides. The longitudinal internal cavity is formed by two superimposed multilayer rectangular absorbent surfaces (4 and 5), fastened on three sides of the perimeter of four, two of which are end (6 and 7) and one side (8). There is an entrance to the internal cavity through the non-bonded fourth lateral side (3) of the perimeter. The waterproof fabric is permanently attached to the rear side (6) of the liner on the side of the external diaper, that is, not on the side of the wearer's body. The waterproof fabric to the back side can, for example, be sewn (9), and to the front side of the insert (7) it is attached, with the possibility of separation, to reusable snap fasteners (10), for example, buttons. Mating latches (11) are located on the front of the insert (7).

After the next use, the waterproof cloth (2) is unfastened from the contaminated liner (1) and in this form the liner is easy to wash, wash, dry and even iron.

The internal cavity is comfortable, large enough and can accommodate various additional liners or just additional absorbent material. The fact that one of its longitudinal edges is stitched greatly limits the possible mutual displacement of the layers, which more reliably fixes the position of additional inserts.

In one or more embodiments (see FIG. 2), the front liner may have additional snap fasteners (12) for attaching the liner to the front of the external diaper from the inside.

In one or more versions (see Fig. 3), the waterproof sheet (2) is additionally equipped with special holes (13), onto which it is fastened with snap fasteners (12) when attaching the liner to the external diaper

In one or more embodiments, the waterproof sheet (2) is additionally provided with perforation zones (14) for additional ventilation and limited wetting outside. In addition, perforation is able to reduce the windage of the waterproof canvas, which will contribute to its more reliable positioning in the desired location. Perforation zones can be located, for example, in corners, around the perimeter, in front, that is, in the least risky places along the course of heavily contaminated feces. At the same time, perforation in different zones can be performed with different densities and with holes of different sizes, depending on the tasks being solved.

In one or more embodiments, the buttons are colored to increase the attractiveness of the product. The response parts of the buttons may also have the same color, to improve the intuitive understanding of the design and to simplify the understanding of the user instructions. At the same time, buttons with different specializations may differ in colors to exclude accidental user errors. For example, the pairs of mates of the buttons for attaching the waterproof fabric to the liner may be yellow, and the pairs of mates of the buttons for attaching the liner to the external diaper may be green.

In one or more versions (see Fig. 4), the insert on the rear side (6) is additionally equipped with a flip back (15) with reusable fastenings (16) to the external diaper from the outside. The flip back of the liner comes out from under the external diaper from the top of the belt (see Fig. 5), is bent along the line P1 through the upper edge of the belt and is attached from the outside of the external diaper on both sides. The mount can be front, rear, sides. The flip back of the liner can be made in a wide variety of designs, solid or composite, permanently or removably attached. For example, it can be made in the form of two straps (17), in the form of a non-thick cloth extension with straps (18), which are provided at the ends with snap fasteners (16) for fastening from the outside of the diaper. It can be just two ribbons (19) that extend outward from above the diaper belt and are attached to the diaper, for example, by its loops or belt loops. Accordingly, the diaper can be equipped with special fasteners, for example, reciprocal fasteners, latches, loops for passing and positioning the straps, etc.

For the manufacture of inserts can be used in various soft absorbent materials, both natural and artificial or synthetic. Materials can be either woven or non-woven. For example, materials containing fibers of organic cotton, hemp, bamboo, viscose and the like can be used. Can also be used materials with special hydrophilic, sorbing, bactericidal, antimicrobial, dirt-repellent or stain-removing properties.

As for the waterproof fabric, it can be either woven or non-woven, can be made of a hydrophobic material, or can have a waterproof coating of plastic, for example polyolefin, polyvinyl chloride, polyurethane, etc. The waterproof fabric may also be breathable.

Utility Model Implementation

Here, an embodiment of the manufacture of an absorbent reusable liner body of the claimed device is described from a soft cloth, for example, gauze. The resulting insert (see Fig. 6) is equipped with an internal cavity with an entrance (3) into it from the lateral edge.

The technology of the present application is illustrated in exemplary embodiments. The word "exemplary" is used here to mean the meaning of "serving as an example, instance or illustration." Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments. In addition, unless otherwise provided, all of the options for implementation presented here should be considered as exemplary.

An exemplary method of manufacturing an absorbent body of a reusable liner according to the present application consists of several stages.

First, a blade with a width of 90 cm is repeatedly folded lengthwise to obtain a multilayer mat (20) with a width H equal to the width of the insert 11 cm. Then, the multilayer web is cut into blanks, three insert lengths L minus two indents q. The length of the liner L is 32 cm, the indent q is 2 cm, the length of the workpiece is 92 cm.

Then the workpiece is successively folded at both ends (21 and 22), the addition is carried out inward along the inflection lines P2 and P3. The length of the end parts of the workpiece imposed by the kink is 30 cm, i.e., the length of the insert minus the indent of 2 cm, and the length of the middle part of the workpiece is equal to the length of the insert 32 cm. When applying the end parts to the middle, soft front and rear ends of the insert are obtained.

After applying the first end part to the middle (23) section (21) of the web does not reach the inflection line P3 of the second end part to an indent of 2 cm. The section (21) is sewn to the middle part along line (24), parallel to the second bend line P3. Then, along the line (25), the longitudinal edges of the superimposed and middle parts of the workpiece are stitched with a deviation of 1 cm from the edge.

Then, the second end part is superimposed on the middle part on top of the sewn first end part, respectively, not reaching an indent q of 2 cm until the bend P2 of the first end part, i.e. the front end of the insert (7). In this case, the first slice (21) is closed on top of the superimposed second end part. Then, to the front of the insert (7), the liner is sewn along the lines (26) and (27) of the pad with fixed buttons (not shown) that are responsive for fastening the waterproof fabric. At the same time, the body of the insert is stitched across and a slice (22) is fixed, and the front border of the internal cavity is also formed.

Then, a waterproof fabric is sewn to the rear side of the liner along line (9). In this case, the rear end (6) of the insert is stitched and the rear border of the internal cavity is formed. Then, the longitudinal edge (8) of the liner is stitched along the line (28) without capturing the waterproof fabric. Thus, the bottom of the inner cavity of the liner is formed.

The result is a multilayer absorbent liner with an internal cavity and a longitudinal side entrance into it, provided with a removable, if necessary, on three sides waterproof sheet.

Both the waterproof canvas and the flip back can be attached to the liner and any other methods known to the person skilled in the art, in accordance with the claimed utility model.
