Description

Absorbent article and method for manufacturing absorbent article {ABSORBENT ARTICLE AND METHOD FOR FABRICATING ABSORBENT ARTICLE}

The present invention relates to an absorbent article that receives feces discharged from the user's body.

Diapers are absorbent articles used by the elderly or physically disabled, and include disposable diapers, training pants, and incontinence pants. Any of these absorbent articles is used in accordance with the wearer's lifestyle and nursing level.

For example, disposable diapers are used as aids for excretion or the like or as nursing hygiene products by maintaining and absorbing the excrement without leaking it to a person who is difficult to excrete by himself, such as an elderly person or a physically disabled person.

Urine can be an important source of information about a user's health. Therefore, there is a need for a method of detecting and managing urine of a user.

Korean Registered Patent Publication No. 1246464 discloses a disposable diaper that can easily take out major parts of men, but there is no way to manage urine.

Korean Registered Patent Publication No. 1246464

The present invention is to provide an absorbent article that can be easily produced while providing a sensor for sensing user's feces.

The technical problems to be achieved by the present invention are not limited to the technical problems mentioned above, and other technical problems that are not mentioned will be clearly understood by those skilled in the art from the following description. Will be able to.

The absorbent article of the present invention is disposed in the excrement area receiving the user's excrement, and the first sheet portion made of vinyl is restricted from passing through the excrement; A second sheet portion stacked on one surface of the first sheet portion facing the user and through which the excrement passes; And a pattern portion disposed between the first sheet portion and the second sheet portion and in which electricity is communicated.

The absorbent article manufacturing method of the present invention includes a printing step of continuously printing or coating a pattern portion in which electricity is communicated to one surface of a first sheet of a vinyl material, through which a user's excretion is restricted; And a bonding step of continuously bonding the second sheet portion through which the excrement is passed to one surface of the first sheet portion on which the pattern portion is printed or coated.

The absorbent article of the present invention may include a pattern part corresponding to a sensor that detects user's excrement.

Since the absorbent article that picks up the feces is one-time, a cost problem is very important.

Therefore, even if a high-performance sensor for detecting the user's excrement is added to the absorbent article, it is difficult to be practically used due to cost problems. This is because the cost increases due to the addition of the sensor. In addition, since the sensor installation process and the connection terminal installation process for connecting the sensor and the sensing terminal must be added separately from the absorption product production process, it is unsuitable for mass production and high-speed production.

According to the absorbent article and its manufacturing method of the present invention, since high-speed mass production of the absorbent article is easy, it is possible to realize the purchase price of the absorbent article including the pattern portion.

Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings. In this process, the size or shape of components shown in the drawings may be exaggerated for clarity and convenience of description. In addition, terms specifically defined in consideration of the configuration and operation of the present invention may vary depending on the intention or custom of the user or operator. Definitions of these terms should be made based on the contents throughout this specification.

1 is an exploded perspective view showing the absorbent article of the present invention.

The absorbent article of the present invention may include a first sheet portion 110, a second sheet portion 120, an absorbent portion 150, a third sheet portion 130, and a pattern portion 200.

The first sheet portion 110 is disposed in the excrement area receiving the user's excrement, and may include a material through which excretion is restricted.

For example, the user's excrement may include feces, urine, sweat, menstruation, tears, saliva, and the like.

To receive each excrement, the absorbent article of the present invention includes a diaper or pad receiving feces, a patch attached to a specific location on the user's body and sweating, a sanitary napkin receiving physiological products, a tear receiving eye patch, a mask receiving saliva, and the like. can do.

The first sheet portion 110 is an element that forms an opposite surface of the absorbent article based on the user's body, and may include materials such as vinyl, film, and the like that are not discharged to the outside.

The first sheet portion 110 may have a different shape in consideration of a user's wearing position and the like, but basically it is preferable to include a sheet in the form of a plate in order to receive a lot of feces.

The second sheet portion 120 may be stacked on one surface of the first sheet portion 110 facing the user, and may include a material through which feces passes.

The absorber 150 may be stacked on one surface of the second sheet unit 120 facing the user, and include materials such as cotton, SAP (Super Absorbtion Polymer), tissue, etc. on which feces are absorbed.

Absorption of cotton or the like is easy to slip on the first sheet portion 110 made of vinyl. At this time, due to the slip, the cotton particles, the SAP particles, and the tissue particles constituting the absorbing portion 150 are shifted in position, so that the absorbing portion 150 is empty on one side of the excretion area and the absorbing portion 150 is driven on the other side. This can happen.

The second sheet portion 120 that is easily bonded to the first sheet portion 110 of the vinyl material may be used to prevent the positional variation of the absorber 150 particles. For example, the second sheet portion 120 that is in contact with the cotton may include a non-woven fabric that passes the excrement and limits the variation in the position of the cotton.

The third sheet portion 130 may be stacked on one surface of the absorbing portion 150 facing the user and include a material through which the excrement passes.

The third sheet portion 130 may function as a cover to prevent the absorbent portion 150 from being separated from the first sheet portion 110 or the second sheet portion 120. In addition, the third sheet portion 130, the cotton particles, SAP particles, tissue particles constituting the absorbing portion 150 is buried in the user's body, or the absorbent excreted in the absorbing portion 150 is buried in the user's body. The phenomenon can be prevented.

The absorbing part 150 and the pattern part 200 may be formed in the excretion area. The first sheet portion 110, the second sheet portion 120, the absorbing portion 150, and the third sheet portion 130 may be formed to be larger than the size covering the excretion area. However, in order to reduce costs, the absorber 150 may be formed to fit the size of the excretion area. In other words, the absorber 150 may be formed to have a smaller size than the first sheet 110, second sheet 120, and third sheet 130. If the size of the absorbent portion 150 is small, the edge of the third sheet portion 130 can be easily bonded to the edge of the second sheet portion 120.

According to the above configuration, along the direction from the outside toward the user's body, the first sheet portion 110, the second sheet portion 120, the absorbing portion 150, the third sheet portion 130 are sequentially stacked Absorbent articles can be provided.

At this time, since the second sheet part 120 and the third sheet part 130 include a material through which the excrement passes, the excrement excreted by the user from the excrement area is from one side of the first sheet part 110 facing the user. Up to the third sheet portion 130 may be present.

The pattern part 200 is for detecting excrement discharged to the excretion area, and may be installed in a section from the first sheet part 110 to the third sheet part 130 where excrement may be present.

The pattern part 200 of the present invention may be disposed between the first sheet part 110 and the second sheet part 120 for cost reduction while maintaining high fecal sensing performance. Also, the pattern unit 200 may include a first pattern 210 and a second pattern 220 corresponding to two lines of electricity.

The pattern part 200 may include a conductive ink 10 printed or coated on one surface of the first sheet part 110 facing the user.

The conductive ink 10 includes at least one of materials including a metal oxide such as carbon, etc. through which electricity is communicated, and a conductive polymer (conductive material such as carbon, polymer, metal oxide, and PEDOT), carbon, and polymer , Solvent for diluting conductive materials such as metal oxides and PEDOT, and water and acetyl corresponding to the solvent of the conductive polymer.

PEDOT is poly(3,4-ethylenedioxythiophene).

If the polymer is largely divided, it can be divided into a performance polymer and a functional polymer. Performance polymers are polymers derived from the properties of polymers and characterized by mechanical or thermal properties. A functional polymer is a polymer in which special properties are expressed according to functional groups present in the polymer, or functional properties are expressed by blending a functional material with the polymer.

Looking at the use of the conductive polymer, the conductive molding material and the conductive film are predominant, and are used in various fields such as for transporting ICs and for transparent electrodes. This field may include techniques for blending polymers with conductivity imparting agents.

The conductive polymer may include polyacetylene, polypyrrole, polythiophene, polyaniline, and the like.

The conductive ink 10 may be initially provided in a liquid or powder state. In order for the conductive ink 10 in a liquid or powder state to be continuously extended, it is preferable to print or coat on a smooth surface without fine holes.

Since the first sheet portion 110 of the present embodiment has a smooth surface such as vinyl or film without micro-pores through which feces can pass, it may be very suitable as a printing object or coating object of the conductive ink 10. If there is only a smooth surface without a fine hole of a size through which the excrement can pass, one side of the first sheet portion 110 may include embossed patterns such as embossing.

Even if the conductive ink 10 is printed or coated on one surface of the first sheet portion 110 at high speed, the conductive ink 10 can be continuously printed or coated, so that productivity can be greatly improved.

The second sheet portion 120 covering the pattern portion 200 may have a fine hole through which the feces pass so that the feces contact the pattern portion 200 formed on one surface of the first sheet portion 110.

2 is a perspective view showing another absorbent article of the present invention. FIG. 3 is a schematic view showing an A-A' cut surface and a B-B' cut surface of FIG. 2.

The absorbent article shown can include a diaper that is filled between the user's legs and receives urine. Each configuration shown can be applied to other types of absorbent articles, such as sanitary napkins.

A pair of tape fasteners 190 may be installed at one edge of the diaper. The tape of the tape fastener 190 may be attached to the other edge of the diaper.

A pair of cuffs 170 for preventing leakage may be provided on both sides of the diaper in an upright position.

The illustrated, first sheet portion 110 includes a transparent material so that the printed or coated pattern portion 200 on one side of the first sheet portion 110 can be seen from the other side of the first sheet portion 110 can do. As a result, as shown in FIG. 2, the presence or absence of the pattern portion 200, the position of the pattern portion 200, and the like can be easily grasped on the other side of the first sheet portion 110.

Since the pattern portion 200 can be confirmed on the other side of the first sheet portion 110, the user can easily align the sensing terminal electrically connected to the pattern portion 200 and detach it from the absorbent article.

The diaper can be formed larger than the actual excretion area to be worn on the user's body. At this time, the absorber 150 may be provided only in the excretion area to improve productivity and wearing comfort.

As a result, the center portion of the diaper including the excretion region includes the first sheet portion 110, the pattern portion 200, the second sheet portion 120, the absorbing portion 150, and the third sheet portion 130 in order. Can be stacked. Since the pattern portion 200 is covered by the thick absorbent portion 150, it may be difficult to visually confirm the surface of the first sheet portion 110 facing the user.

On the other hand, the edge portion of the diaper without the excretion area may be stacked in order, the first sheet portion 110, the pattern portion 200, the second sheet portion 120, and the third sheet portion 130.

At this time, the second sheet portion 120 and the third sheet portion 130 may include a fine hole through which the excrement passes. On one side of the first sheet portion 110 facing the user through the micro-hole, the user can visually confirm the pattern portion 200.

The pattern part 200 may continuously extend from one end of the first sheet part 110 to the other end of the first sheet part 110 in the longitudinal direction of the first sheet part 110.

For example, the first sheet portion 110 and the second sheet portion 120 may have the same specification and be laminated to each other. The second sheet portion 120 may face the first sheet portion 110 with the pattern portion 200 therebetween. At this time, the end of the pattern portion 200 may coincide with the end of the first sheet portion 110 and the end of the second sheet portion 120.

When the pattern part 200 includes the first pattern 210 and the second pattern 220 spaced apart from each other, the ends of the first pattern 210 and the ends of the second pattern 220 coincide with each other. It may be located at the end of the first sheet portion 110 and the end of the second sheet portion 120.

Both ends of the pattern portion 200 may be evacuated from the absorbing portion 150 to be in a state that can be confirmed on one side of the first sheet portion 110.

In addition, the pattern portion 200 exposed to one side of the first sheet portion 110 through the fine holes of the second sheet portion 120 or the third sheet portion 130 is easily in contact with the electrode of the sensing means It can become a state that can be.

In other words, in the absorbent article, the absorbent formed only in the center of the first sheet portion 110 so as not to cover both ends of the pattern portion 200 and the pattern portion 200 continuously extending from one end to the other end of the first sheet portion 110. According to the second sheet portion 120 or the third sheet portion 130 in which the fine holes through which the feces 150 and feces pass are formed, the entire section of the pattern portion 200 escaped from the absorbent portion 150 is a sensing means It can be a terminal that can be connected to the electrode.

At this time, if the electrode of the sensing means is formed in a projection shape capable of penetrating through the second sheet portion 120 or the third sheet portion 130 having a fine hole, there is no need to install a separate connection terminal in the absorbent article. Therefore, the material cost of a separate connection terminal can be reduced.

In addition, when a separate connection terminal is excluded, an additional process for installing a separate connection terminal in the pattern part 200 is excluded, so that high-speed high-volume production of absorbent articles is possible. As a result, the cost of the absorbent article provided with the pattern portion 200 can be realized.

The pattern unit 200 may include a first pattern 210 and a second pattern 220 that are spaced apart from each other and penetrate the excretion region so that the equivalent resistance of the pattern unit 200 is changed by excrement.

As an example, it is assumed that the first electrode of the sensing terminal contacts the first point ① of the first pattern 210 and the second electrode of the sensing terminal contacts the second point ② of the second pattern 220. .

At this time, the sensing terminal may detect the equivalent resistance of the pattern unit 200 based on the first point ① and the second point ②. Since the first pattern 210 and the second pattern 220 are spaced apart from each other, the equivalent resistance value may be very high. When the user's excrement fills between the first pattern 210 and the second pattern 220, the equivalent resistance value of the pattern portion 200 may be lowered due to some conductivity of the excrement.

In this case, when the equivalent resistance value of the pattern unit 200 becomes smaller than the set value, the sensing terminal may determine that excrement is present.

The equivalent resistance of the pattern part 200 decreases as the area of the excrement increases, and the sensing terminal can grasp the area of the excrement using the equivalent resistance value of the pattern part 200.

If the sensing terminal knows the absorption rate per unit area of the absorbent article, the sensing terminal can determine the amount of excretion using the identified area of the excrement and the absorption rate per unit area.

Meanwhile, the first pattern 210 and the second pattern 220 may be formed in parallel wire shapes. At this time, since the excrement finely present between the first pattern 210 and the second pattern 220 does not contact the first pattern 210 and the second pattern 220 at the same time, the change in the equivalent resistance value is set. The value may not be satisfied. In this case, the sensing terminal may not detect feces.

In order to detect fine feces present between each pattern and improve fecal detection performance, a first wing 211 protruding toward the second pattern 220 may be provided in the first pattern 210. Similar to the first wing 211, the second pattern 220 may be provided with a second wing 221 protruding toward the first pattern 210.

4 is a schematic view showing a process of printing or coating the pattern portion 200 on the first sheet portion 110.

As another effect of the pattern portion 200 continuously extending from one end of the first sheet portion 110 to the other end, the productivity of the first sheet portion 110, the second sheet portion 120, and the pattern portion 200 itself This can be improved. This may also be a major factor enabling high-speed mass production.

For example, for high-speed mass production, the first sheet portion 110 may be provided in a rolled roll. In the process of manufacturing the absorbent article, the first sheet portion 110 may be released while the first roll a on which the first sheet portion 110 is dried rotates.

At this time, the pattern portion 200 may be continuously printed or coated on the first sheet portion 110 along the direction in which the first sheet portion 110 is released.

As an example, the pattern part 200 may be printed or coated on the first sheet part 110 through gravure printing.

The ink container 330 in which the conductive ink 10 in the liquid or powder state is accommodated, the cylindrical plate gravure rotary machine 310, the cylindrical plate in which the outer circumferential surface rotates while passing through the ink container 330 and the intaglio shape of the pattern portion 200 is formed on the outer circumferential surface It may include a flat plate gravure wheel press 320 disposed facing the gravure wheel press 310. A doctor blade 340 (doctor blade) for adjusting the thickness of the conductive ink 10 on the outer circumferential surface at a position facing the cylindrical plate gravure rotary machine 310, and a pressure roller for maintaining the first sheet portion 110 taut ( 350) may be additionally provided.

The first sheet portion 110 released from the first roll a may be inputted between each wheel, and printed or coated with a conductive ink 10 between each wheel. At this time, the conductive ink 10 printed or coated on one surface of the first sheet portion 110 forms the pattern portion 200 and may be naturally dried or dried through the dryer 360. The first sheet portion 110 where the conductive ink 10 is dried becomes the first sheet portion 110 having the pattern portion 200, and the first sheet portion 110 having the pattern portion 200 rolls again. Can be dried. At this time, the roll on which the first sheet portion 110 having the pattern portion 200 is dried is referred to as a pattern roll b.

Looking at the above manufacturing process, the pattern portion 200 may be continuously formed over the entire section of the first sheet portion 110 forming the first roll a.

Since it is difficult to apply the entire first sheet portion 110 forming the first roll a as one absorbent article, it is possible to obtain a plurality of first sheet portions 110 applicable to a real user by cutting to an appropriate length. . At this time, the length of each first sheet portion 110 may vary depending on the type of excrement, the application age, and the like. According to the present invention, since the pattern portion 200 is continuously formed without having to consider the first sheet portions 110 having different lengths, productivity can be improved.

On the other hand, if the pattern portion 200 is intermittently printed in accordance with the first sheet portion 110 having different lengths, the cylindrical plate gravure rotary machine 310 needs to be replaced according to the specification of the first sheet portion 110. A decrease in productivity is expected.

5 is a schematic view showing a process of bonding the first sheet portion 110 and the second sheet portion 120.

The second sheet portion 120 may be provided in a second roll c state.

When the second sheet portion 120 is released while the second roll c on which the second sheet portion 120 is pushed is rotated, the first sheet portion 110 on which the pattern portion 200 is printed or coated is the second sheet portion ( 120) may be continuously bonded to the second sheet portion 120 along the unwinding direction. Bonding between the first sheet portion 110 and the second sheet portion 120 may be performed by thermal fusion, high-frequency fusion, adhesion through an adhesive, or the like. When the first sheet portion 110 and the second sheet portion 120 are joined, the pattern portion 200 printed or coated on one surface of the first sheet portion 110 includes the first sheet portion 110 and the second sheet. It may be interposed between the parts 120.

The first sheet portion 110 that has passed through the dryer 360 of FIG. 4 may be directly input to the bonding rollers 370 and 380 that bond the first sheet portion 110 and the second sheet portion 120. In this case, the bonding rollers 370 and 380 may be disposed downstream of the dryer 360 of FIG. 4. Alternatively, the joining rollers 370 and 380 may be input while the first sheet unit 110 dried in the pattern roll b is released. Fig. 5 shows the latter case. In this case, the bonding rollers 370 and 380 may be disposed independently for each rotary machine or dryer 360 of FIG. 4.

FIG. 6 is a schematic view showing a cutting process of a bonded body in which the first sheet portion 110 and the second sheet portion 120 are joined.

The first sheet portion 110 and the second sheet portion 120 joined to each other by the bonding rollers 370 and 380 may be cut to a length capable of covering the excretion area.

The bonding material z to which the first sheet portion 110 and the second sheet portion 120 are joined is rolled in a rolled state, transported to the cutter 390, or output from the bonding rollers 370 and 380 and then located downstream. It can be entered directly at (390).

Through the cutting of the cutter 390, a pattern portion 200 that continuously extends from one end of the first sheet portion 110 to the other end may be formed.

The plurality of joints z cut by the cutter 390 may be the diaper of FIG. 2 through an additional lamination process of the absorber 150 and the third sheet 130.

Looking at the above processes, the pattern portion 200 is printed or coated on the first sheet portion 110, the second sheet portion 120 is bonded, and a high-speed cutting process is performed whenever necessary. You can.

For example, compared to a general absorbent article, although the overall process time increases as much as the process time of printing or coating the pattern portion 200 on the first sheet portion 110, once a single absorbent article is completed, Absorbent articles can be produced at the same rate as regular absorbent articles. As a result, cost savings due to production equipment and production speed can converge to the production of general absorbent articles.

The absorbent article manufacturing method of the present invention may include a printing step, a bonding step, an absorbing part 150 laminating step, and a cover laminating step.

The printing step illustrated in FIG. 4 may include a process of continuously printing or coating the pattern portion 200 in which electricity is communicated to one surface of the first sheet portion 110 in which passage of the user's feces is restricted.

For example, the printing step may include providing a first roll a wound around the first sheet portion 110 and releasing the first sheet portion 110 while rotating the first roll a. The printing step uses the flat plate gravure presser 320 and the cylindrical plate gravure presser 310 provided on the movement path of the first sheet part 110 released from the first roll A to form the pattern part 200 into the first sheet part ( 110) may be continuously printed or coated. In the printing step, the printed or coated pattern portion 200 is dried on the first sheet portion 110, and the first sheet portion 110 having the dried pattern portion 200 can be wound to form a pattern roll b. have.

In the printing step, the first sheet 210 and the second pattern 220 that pass through the excretion area receiving the user's excrement are spaced apart from each other so that the equivalent resistance of the pattern part 200 varies according to the excrement of the user. It may be printed or coated on the part 110.

The bonding step illustrated in FIG. 5 may include a process of continuously bonding the second sheet portion 120 through which the excrement passes through one surface of the first sheet portion 110 on which the pattern portion 200 is printed or coated. .

For example, in the bonding step, a second roll c wound by the second sheet portion 120 may be provided, and the second sheet portion 120 may be released while rotating the second roll c. In the bonding step, the second sheet part 120 released from the second roll c enters the bonding rollers 370 and 380 together with the first sheet part 110 on which the pattern part 200 is printed or coated, and the bonding roller ( 370 and 380 may be used to bond the first sheet portion 110 and the second sheet portion 120.

The stacking of the absorber 150 may include a process of stacking the absorber 150 disposed in the excretion area receiving the user's excrement on the second sheet 120.

The cover laminating step may include a process of laminating a third sheet portion 130 through which feces passes on the absorbing portion 150.
