Description

Notification Diaper{Alam Diaper}

The present invention relates to a diaper that can visually confirm urine and stool, and in particular, to a notification diaper that can be visually confirmed when an infant or a person with reduced mobility urinates while wearing a diaper. it's about

In general, diapers are used to receive urine and feces of people who cannot cover urine and feces (eg, infants and dementia patients) or people with reduced mobility (eg, patients and the elderly). A person who wears a diaper cannot change the diaper by himself or herself after having a bowel movement, and usually a guardian (eg, a parent, a family member, a nurse, a daycare worker, etc.) changes the diaper.

However, since infants or dementia patients cannot express their opinions properly even after urinating or having a bowel movement, they often wear diapers with excrement for a long time. In this case, there is a risk of damaging the skin of the diaper wearer due to the toxicity of the excrement and the moisture contained in the excrement.

That is, wearing a diaper covered with excrement for a long time, there is a risk of various skin diseases such as skin rash or eczema. In addition, in order to prevent the diaper wearer from wearing the diaper stained with excrement for a long time, the guardian has the inconvenience of frequently checking whether the diaper wearer has urinated.

In order to solve this inconvenience, a diaper in which a sensor (eg, a moisture sensor) for detecting feces and urine is mounted on a diaper according to a conventionally proposed technique to sound a warning sound when urination is detected has also been developed.

Such a diaper has the advantage of being able to check the presence or absence of urine or feces through a warning sound even when the wearer's clothes are not removed, but on the other hand, there is a lot of difficulty in wearing the diaper due to the need for a separate device for operating the sensor. There is a problem that the sensor does not work due to sensor contamination. In addition, there is a problem that can give shame to the elderly or patients.

In addition, since the diaper to which the sensor is mounted as described above needs to be provided with a warning generating device in the disposable diaper, there are problems in that it is inconvenient to attach the device to the body, increases the price of the product, and is complicated to manufacture.

In addition, the existing diaper that detects urine and feces has a problem in that children use the diaper too much because a large-to-small-mouth notification is generated even when children urinate.

Other objects, features and advantages of the present invention will become apparent from a detailed description of the embodiments with reference to the accompanying drawings.

The terms used in the present invention have been selected as currently widely used general terms as possible while considering the functions in the present invention, but these may vary depending on the intention or precedent of a person skilled in the art, the emergence of new technology, and the like. In addition, in a specific case, there is a term arbitrarily selected by the applicant, and in this case, the meaning will be described in detail in the description of the corresponding invention. Therefore, the term used in the present invention should be defined based on the meaning of the term and the overall content of the present invention, rather than the name of a simple term.

A preferred embodiment of the notification diaper according to the present invention will be described with reference to the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various different forms, only this embodiment allows the disclosure of the present invention to be complete and the scope of the invention to those of ordinary skill in the art completely It is provided to inform you. Therefore, the configuration shown in the embodiments and drawings described in the present specification is only the most preferred embodiment of the present invention and does not represent all the technical spirit of the present invention, so various equivalents that can replace them at the time of the present application It should be understood that there may be water and variations.

In the following, that an arbitrary component is disposed on the "upper (or lower)" of a component or "top (or below)" of a component means that any component is disposed in contact with the upper surface (or lower surface) of the component. Furthermore, it may mean that other components may be interposed between the component and any component disposed on (or under) the component.

1 is a cross-sectional view showing the configuration of a notification diaper according to an embodiment of the present invention, and FIG. 2 is a notification line (feces notification line, primary urine notification line, secondary urine notification line) in the notification diaper according to an embodiment of the present invention. ) is a configuration diagram showing the configuration exposed to the outside.

At this time, the notification diaper shown in Figs. 1 and 2 is according to an embodiment, and the components are not limited to the embodiment shown in Figs. 1 and 2, and some components are added or changed as needed. Or it can be deleted.

As shown in Fig. 1, the notification diaper 100 of the present invention has a front waist region, a rear waist region, and a crotch region located between the front and rear waist regions, A disposable diaper having a longitudinally absorbent structure extending to a peripheral region, comprising an inner sheet (10) and an outer sheet (60), and a stool notification line between the inner sheet (10) and the outer sheet (60) ( 20), the primary urine notification line 30, the absorption layer 40, and the secondary urine notification line 50 may be sequentially stacked.

The inner sheet 10 may be disposed on the surface of the skin-contacting side, and may be composed of various fibrous nonwoven fabrics or tissue sheets having liquid permeability. For example, an air-through fiber nonwoven fabric having a mass of about 10 to 30 g/m2, a spunbond nonwoven fabric, an SMS (spunbond-meltblown-spunbond) nonwoven fabric, or a tissue sheet having a mass of about 10-30 g/m2 can be used. .

The outer sheet 60 is disposed on the surface of the skin non-contact side, and may be composed of various fibrous nonwoven fabrics or tissue sheets having liquid impermeability.

The inner sheet 10 and the outer sheet 60 may use a non-woven fabric sheet having a high specific weight portion and a low basis weight portion alternately in the product width direction. By using such an inner sheet 10, the force is concentrated at the boundary between the high basis weight portion and the low basis weight portion, which is preferable for the elongation of the stretchable region, and the elongation can be expressed.

And the nonwoven fabric sheet constituting the inner sheet 10 or the outer sheet 60 is a sheet having no thermal fusion point by point or line embossing or a sheet having an area ratio of point or line embossing of 5% to 15% can be composed of The area ratio of embossing is the ratio of the area in which the embossing is formed. For example, with respect to the total area of the outer sheet 60 , it is the area of the embossed portion of the outer sheet 60 .

The absorbent layer 40 may include an absorbent core that absorbs urine and feces between the inner sheet 10 and the outer cover 60 . That is, the absorption layer 40 is surrounded by the inner layer sheet 10 and the outer cover 60 .

The absorbent core is the same as that of a conventional disposable diaper, and can be suitably constructed using a known member or material such as pulverized pulp or a superabsorbent polymer.

The primary urine notification line 30 is positioned between the inner sheet 10 and the absorbent layer 40, and may change color by generating a chemical reaction with weakly acidic urine when in contact with urine. In this case, the chemical reaction may include, for example, a color change of the litmus paper by a chemical reaction using the litmus principle. However, the chemical reaction is not limited thereto, and a chemical reaction using a material that changes color when wet with water may be used regardless of the pH of urine.

As shown in FIG. 2 , the primary urine notification line 30 may be configured to extend so that one end thereof is exposed to the outside of the notification diaper 100 . To this end, the primary urine notification line 30 may be configured in a thin band type (rope type) having a constant width.

At this time, as the primary urine notification line 30 is positioned between the inner sheet 10 and the absorbent layer 40 , the urine transmitted through the inner sheet 10 when a wearer wearing a diaper urinates. This can be directly contacted. Accordingly, the primary urine notification line 30 can be determined when the wearer peeps urine or a small amount.

The secondary urine notification line 50 is positioned between the absorbent layer 40 and the outer sheet 60, and may change color by generating a chemical reaction with weakly acidic urine when in contact with urine. In this case, the secondary urine notification line 50 may be made of the same material as the primary urine notification line 30 .

As shown in FIG. 2 , the secondary urine notification line 50 may be configured to extend so that one end thereof is exposed to the outside of the notification diaper 100 . To this end, the secondary urine notification line 50 may be configured in a thin band type (rope type) having a constant width.

At this time, as the secondary urine notification line 50 is positioned between the absorbent layer 40 and the outer sheet 60, when a wearer wearing a diaper urinates, the inner sheet 10 and the absorbent layer ( 40) can only come into contact with permeated urine. Accordingly, the secondary urine notification line 50 is not discriminated when the wearer peeps urine or a small amount, and can be discriminated when the wearer sees a large amount of urine wet to the lower end of the absorbent layer 40 .

Therefore, the guardian can easily check the amount of urine when a wearer wearing a diaper urinates using the primary urine notification line 20 and the secondary urine notification line 50 .

The stool notification bar 20 may be positioned between the inner sheet 10 and the absorbent layer 40, and may change color by generating a chemical reaction with weakly basic stool when in contact with the stool. In this case, the chemical reaction may include, for example, a color change of the litmus paper by a chemical reaction using the litmus principle. However, the chemical reaction is not limited thereto, and various chemical reactions using a material that changes color due to the weak basicity of feces may be used.

Meanwhile, in FIG. 1 , the stool notification line 20 is illustrated to be positioned above the primary urine notification line 30 , but is not limited thereto, and is located above the primary urine notification line 30 . can be

As shown in FIG. 2 , the stool notification line 20 may be configured to extend so that one end thereof is exposed to the outside of the notification diaper 100 . To this end, the stool notification line 20 may be configured in a thin band type (rope type) having a constant width.

At this time, as the stool notification line 20 is located between the inner sheet 10 and the absorbent layer 40, when a wearer wearing a diaper sees a stool, the stool transmitted through the inner sheet 10 is immediately can be contacted. Accordingly, the stool notification line 20 can be immediately determined when the wearer has defecated.

On the other hand, the primary urine notification line 20, the secondary urine notification line 50 and the stool notification line 40 are a single band-type and have independent channel lines and are combined into one urine notification line. can be configured. However, the present invention is not limited thereto, and if the urine and feces notification lines 20, 50, and 40 are provided as channel lines independent of each other, they may also be configured as two or three notification lines.

In this way, the notification diaper 100 of the present invention can be visually confirmed quickly when an infant or a person with reduced mobility urinates while wearing a diaper through the urine notification line 20, 50, 40, and the urine It is possible to visually tell at a glance whether the stain is slightly smeared or wet.

Hereinafter, a method for manufacturing a notification diaper according to the present invention configured as described above will be described in detail. The same reference numerals as those of FIG. 1 or FIG. 2 refer to the same members performing the same functions.

The manufacturing method of the notification diaper of this invention manufactures a continuum in which a diaper is continuous in the product longitudinal direction, and cuts the continuum to the size of one product along the product width direction W, whereby individual disposable diapers to manufacture

And in the component part forming process, the component component which comprises a diaper is formed. Specifically, on the continuous web constituting the outer sheet 60, the web constituting the waist elastic sheet or the inner sheet 10, etc., the secondary urine notification line 50, the absorbent layer 40, the primary urine notification Component parts constituting the diaper 100 such as the string 30 and the stool notification line 20 are disposed.

At this time, a waist elastic sheet is the state in which the front side waist elastic sheet of an arbitrary diaper, and the rear side waist elastic sheet of the disposable diaper adjacent to that arbitrary disposable diaper were integrated. The elastic sheet is held at both ends (the portion that becomes the outer end in the product width in a state of being molded into a diaper) by a suction means or the like, and the elastic sheet is stretched in the product width direction of the disposable diaper, and is affixed on a continuous web. Since the elastic sheet is stretched with both ends of the elastic sheet held, both ends of the elastic sheet are hardly stretched. The elongation rate in the product width direction at both ends of the elastic sheet is lower than the elongation rate in the product width direction in the region between the both ends.

The elongation in the width direction of the product in the central region can be 1.4 to 1.8 times. The elongation rate in the product width direction in the side region is set lower than the elongation rate in the product width direction in the center region, and may be 1.0 to 1.1 times. The elongation rate in the product width direction in the middle region is set lower than the elongation rate in the product width direction in the central region and higher than the elongation rate in the side region, and may be 1.2 times to 1.3 times. Moreover, the area|region in which the elongation rate of the product width direction of a side area|region is 1.0 times and a side area|region does not extend substantially may be sufficient.

Further, the stretchable sheet stretched in the product width direction decreases in width in the product length direction. In particular, the width of the center in the product width direction of the elastic sheet decreases. Accordingly, in the stretched elastic sheet, the length in the product longitudinal direction at the center in the product width direction is shorter than the length in the product longitudinal direction at the end portion in the product width direction. In the elastic sheet affixed in such a reduced width state, the rear end of the front waist elastic sheet corresponding to the end of the elastic sheet in the product longitudinal direction and the front end of the rear waist elastic sheet are curved in the center of the width direction rather than the outer side in the width direction. becomes the shape.

In the leg circumference forming step, the inner sheet 10 and the outer sheet 60 are cut. Accordingly, an opening disposed around the wearer's leg is formed. In the cutting process, a continuum in which the inner sheet, the stool notification line 20, the primary urine notification line 30, the absorbent layer 40, the secondary urine notification line 50 and the outer sheet 60, etc. are arranged, is cut by the product width Cut to the size of one product along the direction (W). Accordingly, the notification diaper 100 is manufactured.

When the continuum is cut for each product, the stretched state of the waist elastic sheet and the leg elastic portion provided on the diaper is released and becomes a natural state. When the stretched state is released, the waist elastic sheet in a state in which the width is reduced at the time of extension is deformed so as to return to the state before the decrease in width. Therefore, although the rear side edge part of a rear side waist elastic sheet and the front side edge part of a front side waist elastic sheet were linear in an extended state, it deform|transforms into a curved state in a natural state.

In addition, when the continuum is cut for one product and in a natural state, the front end of the front waist elastic sheet is shrunk than the rear end of the front waist elastic sheet, and the rear end of the rear waist elastic sheet is the front end of the rear waist elastic sheet more constricted The front end of the front waist elastic sheet is farther from the absorbent layer 40 than the rear end of the front waist elastic sheet, and since the rigidity of the absorbent layer 40 is not affected, it is further contracted. The rear end of the rear waist elastic sheet is farther from the absorbent layer 40 than the front end of the rear waist elastic sheet, and since the rigidity of the absorbent layer 40 does not affect it, it is further contracted.

The front end of the front waist elastic sheet is contracted from the rear end of the front waist elastic sheet, so that the center of the product width direction of the front end of the disposable diaper is concave in the product longitudinal direction rather than the product width direction outside of the front end of the diaper. do. Similarly, when the rear end of the rear waist elastic sheet is contracted from the front end of the rear waist elastic sheet, the product width direction center of the rear end portion of the diaper is concave in the product longitudinal direction rather than the product width direction outer side of the rear end portion of the diaper. becomes this
