Description

Pad for Pet Having Surge Layer

The present invention relates to a pet pad for treating a feces of a pet, and more particularly, to a pet pad having a surge layer capable of quickly absorbing the liquid contained in the feces.

In general, in order to process the excretion of pets, such as dogs and cats raised in the home, in the past has been using a material that can absorb the moisture contained in the excrement, such as newspapers, paper boxes, etc., but in recent years Pet pads are also used.

Such pet pads typically have a structure comprising a liquid permeable surface layer, a liquid impermeable back layer, and an absorbent layer disposed between the surface layer and the back layer to absorb liquid.

At this time, the surface layer functions to allow liquid components, such as urine, contained in the feces of the pet to pass through and move to the adjacent absorbing layer, and the absorbing layer has a function of receiving and absorbing and retaining the liquid introduced from the surface layer, and the back layer is a liquid fire. It is made of a permeable film material to perform the function of preventing the liquid held in the absorbing layer to be discharged to the outside.

However, such a conventional pet pad has a low amount of liquid absorption in the feces, a slow absorption rate of the liquid, or an amount of liquid flowing back to the surface layer when the pad containing the liquid is pressurized (rewet amount, In the following, there is a problem in that the properties related to absorbency are poor, such as a large amount of 'backflow amount', and thus the inconvenience of use and low reliability.

In addition, the conventional pet pad has a problem that a lot of odor is generated due to insufficient adsorption of odor-causing components such as ammonia, methyl mercaptan, trimethylamine generated in the excrement.

Therefore, there is a need for pet pads with improved absorbency and / or deodorization.

An object of the present invention is to provide a pet pad having at least one of an absorption amount, an absorption rate, and a reflux amount of a liquid component included in a feces of a pet as an aspect. .

In addition, an object of the present invention is to provide a pet pad excellent in deodorizing effect by sufficiently reducing the various odor causing substances generated in the feces of the pet.

In addition, an object of the present invention is to provide a pet pad that can be fixed to the pad without a separate fixing device such as a rug or a tray for fixing the pad.

In addition, an object of the present invention is to provide a pet pad that can reduce the volume of the discarded pads, because the pad does not spread when discarded after use of the pad, the pads are discarded.

As one aspect for achieving the above object, the present invention, a liquid permeable surface layer; Liquid impermeable backing layer; An absorbent layer disposed between the surface layer and the rear layer, the absorbent layer absorbing and storing a liquid; And a surge layer positioned between the surface layer and the absorbent layer and discharging the liquid absorbed from the surface layer to the absorbent layer.

Preferably, the surge layer comprises at least one of an SMS (spunbond-meltblown-spunbond) nonwoven fabric, an adhesive carding web, an airlaid web, a through air bonded carded web (TABCW). It can be done by.

Also preferably, the absorbing layer may include a sheet of SAP (Super Absorbent Polymers).

Preferably, the absorbing layer may include a monomolecular compound having a carboxyl group.

In this case, the monomolecular compound having a carboxyl group is selected from the group consisting of citric acid, acetic acid, lactic acid, lactic acid, tartaric acid, and succinic acid. It may consist of a species or two or more compounds.

Preferably, at least one of the surge layer, the absorbing layer, and the surface layer may contain a charcoal or activated carbon component.

Also preferably, the surge layer may be dyed, printed, coated or coated with ink, dye or pigment containing char or activated carbon components.

On the other hand, the pet pad according to the present invention is an adhesive portion disposed below the rear layer; And release paper is attached to protect the adhesive portion; may further include.

As described above, the pet pad according to the present invention is provided with a surge layer to widely disperse the liquid components contained in the feces of the pet, so that the liquid is partially concentrated in one place, so that only a portion of the corresponding absorption layer absorbs the liquid. It is possible to prevent the swelling to improve the efficiency of the absorber layer as well as to increase the liquid absorption rate.

In addition, in the pet pad according to the present invention, since the surge layer is disposed between the surface layer and the absorbent layer to form a space between the surface layer and the absorbent layer, the liquid flows from the surface layer to the absorbent layer is again exposed through the surface layer. There is an effect that can be suppressed.

According to the present invention, odor-inducing factors such as ammonia, trimethylamine, methyl mercaptan, etc. may be formed by including char or activated carbon in the surface layer, the surge layer, and the absorption layer, and / or by including the monomolecular compound having a carboxyl group such as citric acid in the absorption layer. By absorbing sufficiently, the effect that the deodorizing effect is excellent can be obtained.

According to the present invention, the activated carbon can be easily contained in the surge layer by printing, dyeing, applying or coating the ink, pigment, dye or the like containing charcoal or activated carbon, thereby forming various patterns on the surge layer. Not only that, but also the aesthetics can be improved.

In addition, the present invention not only does not require a separate device (tray, pallet, etc.) for fixing the pad by fixing the pad to the bottom surface using an adhesive part, and can use the pet pad anywhere regardless of place. It has an effect.

In addition, the present invention can prevent the pads from spreading out again by adhering the pads using an adhesive part after using the pet pads, as well as preventing the excretion from flowing out, and reducing the volume of the discarded pads. The effect can be obtained.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view of a pet pad according to an embodiment of the present invention, Figure 2 is a cross-sectional view of the pet pad shown in Figure 1, Figure 3 is a plan view showing the surface of the surge layer.

1 and 2, the pet pad 100 according to an embodiment of the present invention has a surface layer 110, a surge layer 140, an absorbing layer 130, and a rear layer 120 from an upper side thereof. ), And may further include an adhesive part 150 and a release paper 160 disposed under the rear layer 120.

The surface layer 110 is a portion in which the feces directly contact when the pet is excreted, the liquid contained in the feces of the pet easily passes through the surge layer 140 disposed in the lower portion quickly moves to the absorbing layer 130 Let's do it. For this purpose, the surface layer 110 is advantageous to have the properties of hydrophilicity and porosity. In addition, the surface layer 110 may be made of a bulky nonwoven material having a relatively low density. As an example, a nonwoven fabric such as spun bond (SB) or thermally bonded carded web (TBCW) may be used for the surface layer 110, but the material is not particularly limited as long as it has liquid permeability.

The surge layer 140 is disposed between the surface layer 110 and the absorber layer 130 to provide liquid alternating contact with the surface layer 110 and the absorber layer 130 to efficiently transfer liquid from the surface layer 110 to the absorber layer 130. To be placed. This surge layer 140 quickly collects and temporarily retains the liquid contained in the feces of the pet, dispersing the liquid widely from the initial point of contact to other portions of the surge layer 140, and then dispersing such liquid into the absorbent layer 130. ) To release. That is, the surge layer 140 sucks the pet's urine and the like and disperses it not only in the vertical direction (direction toward the absorption layer 130) but also in the left and right directions (other portions of the surge layer 140), Due to the liquid gathered in one place, only the portion of the absorption layer 130 corresponding to this can prevent the liquid from being swollen.

In addition, since the surge layer 140 is disposed between the surface layer 110 and the absorbent layer 130 to form a space between the surface layer 110 and the absorbent layer 130, the liquid moved from the surface layer 110 to the absorbent layer 130 is Again, it acts to minimize the rewet exposed through the surface layer 110.

Various surge and nonwoven webs may be used for the surge layer 140. For example, surge layer 140 may be formed of a spunbond-meltblown-spunbond (SMS) nonwoven fabric, an adhesive carding web, an airlaid web, a through air bonded carded web (TABCW). It may include at least one.

In addition, as the raw material of the surge layer 140, one or some of PE, PP, PE / PP bicomponent fiber, and PET fiber may be used in combination.

In addition, the absorber layer 130 is disposed between the surge layer 140 and the rear layer 120 disposed below the surface layer 110, and rapidly absorbs liquid from the surface layer 110 and absorbs the liquid to an amount that can be retained. Will be maintained. In addition, the absorber layer 130 may have a smaller area than the surface layer 110 or the rear layer 120 so as not to be exposed to the outside of the surface layer 110 and the rear layer 120.

The absorbent layer 130 may be a sheet of SAP (Super Absorbent Polymers) having excellent water retention. The SAP sheet is formed by compressing a super absorbent material (SAM, Super Absorbency Material), pulp, tissue, and the like through a compression roll. Since the SAP sheet has a compressive structure, it not only prevents the super absorbent material (SAM) from escaping but also prevents the pulp from moving even when the liquid enters and the super absorbent material expands, thereby maintaining the shape of the pad 100. It becomes possible.

On the other hand, it is known that the monomolecular compound having a carboxyl group has an absorption effect on ammonia, amines and the like.

Pet pad 100 according to an aspect of the present invention can increase the deodorizing effect of ammonia, amine series by including a monomolecular compound having such a carboxyl group in the absorbent layer 130.

Examples of the monomolecular compound having a carboxyl group include i) acetic acid, lactic acid, citric acid, tartaric acid and succinic acid, ii) as food additives. Lauric acid, myristic acid, palmitic acid, stearic acid, behenic acid, oleic acid, linolenic acid Linolenic Acid, Arachidic Acid, Ricinoleic Acid, Organic Acids of Vitamins, and Amino Acids, Benzoic Acid, Pyruric Acid ), Fumaric acid, maleic acid, malic acid, propionic acid, bytyric acid, caproic acid, oxalic acid, alginic acid ), Ethoxyacetic acid, glucuronic acid, salicylic acid, Acid or the like (Cinamic Acid), deoxy claw acid (Deoxycholic Acid) and egg Plano acid (Allofuranoic Axid) is known.

In consideration of stability aspects to the human body and pets, the pet pad 100 according to the present invention includes citric acid, acetic acid, lactic acid, tathalic acid, which are used as food additives in the above-described monomolecular compounds having a carboxyl group. It is preferable to use one or two or more compounds selected from the group consisting of succinic acid or organic acids of vitamins. However, in this invention, the kind of monomolecular compound which has a carboxyl group is not specifically limited.

In addition, the back layer 120 serves to prevent the liquid component contained in the absorbent layer 130 from wetting or staining a part or other object of the human body in contact with the pad 100. In this regard, the back layer 120 is typically formed of a thin film thermoplastic film such as a polyethylene film that is liquid impermeable, but the material is not particularly limited as long as it has liquid impermeability.

The surface layer 110, surge layer 140, absorber layer 130 and back layer 120 described above are assembled in the form of a pad 100 using conventional techniques known in the art. For example, the layers 110, 120, 130, and 140 may be stacked on each other by a suitable method such as thermal bonding, physical bonding such as pressing, ultrasonic bonding, or bonding, to form the pad 100.

Preferably, the pet pad 100 according to the present invention may contain a charcoal or activated carbon component in the surface layer 110, the surge layer 140, the absorber layer 130, and the like. That is, the char or activated carbon component may be included in the form of particles in the surface layer 110, the surge layer 140, the absorber layer 130, or the like, or may be applied in the form of particles on the surface. It may be dyed, printed, applied or coated using the ink, dye or pigment contained therein.

As such, when the pad 100 contains charcoal or activated carbon, the pets can implement a deodorizing effect by adsorbing components such as ammonia, methylmercaptan, trimethylamine, and the like, which cause odors in the feces. . In particular, as will be described later, the char and activated carbon components show a particularly good deodorant effect for trimethylamine.

This deodorizing effect can be expected when the char or activated carbon component is contained in the surface layer 110, the surge layer 140, and the absorbent layer 130, but when contained in the surface layer 110, there is a fear that the deodorizing effect to the outside. In the present invention, the surge layer 140 or the absorbing layer 130 is preferably, but is not limited thereto.

In particular, when the surge layer 140 contains charcoal or activated carbon components, the liquid contained in the excrement penetrates the surge layer 140 and the odor causing substance is absorbed by the char or activated carbon component, and the liquid retained in the absorbing layer 130 is included. Odor-inducing material generated in the absorbed while passing through the surge layer 140 located on the upper side of the absorbing layer 130 may have a dual absorption effect.

On the other hand, in order to contain the char or activated charcoal component in the surge layer 140, it may be dyed, printed, coated or coated using an ink, dye or pigment containing the char or activated charcoal component in the surge layer 140.

As such, when taking a method of printing, dyeing, coating or coating, there is an advantage that activated carbon may be included in the surge layer 140 in manufacturing.

In addition, by the ink, dye or pigment containing a charcoal or activated carbon component on the surface of the surge layer 140 is dyed, printed, applied or coated, a character-shaped pattern (see 141 in FIG. 1), a grid-shaped pattern (in FIG. 3). By forming various patterns such as 142), an aesthetic effect can be improved as compared to a conventional pad having no pattern.

Since the components and manufacturing methods of the ink, dye or pigment containing the charcoal or activated carbon components are already known, a detailed description thereof will be omitted.

In particular, the ink, dye or pigment containing a charcoal or activated carbon component on the surface of the surge layer 140 is dyed, printed, coated or coated, and a monomolecular compound having a carboxyl group such as citric acid is included in the absorbent layer 130. In this case, the deodorizing effect on all of ammonia, trimethylamine, and methyl mercaptan can be increased.

Meanwhile, the pet pad 100 according to the present invention may further include an adhesive part 150 disposed below the rear layer 120 and a release paper 160 attached to protect the adhesive part 150. have.

The adhesive part 150 may fix the pad 100 to the bottom surface, and preferably has adhesive strength enough to be separated from the bottom surface after use. If the adhesive portion 150 has such adhesive strength, a known adhesive means such as a double-sided tape is used. Can be ...

The adhesive unit 150 may have various shapes and arrangements to be easily fixed to the bottom surface. For example, as shown in FIG. 1, the adhesive part 150 may be configured to be arranged in three rows at the center of the bottom surface of the back layer 120, but is not limited thereto. If attached, they can have a variety of shapes and arrangements.

Since the pad 100 may be fixed to the bottom surface through the adhesive part 150, the pad 100 may be used without using a separate fixing device (for example, a tray or a pallet) for fixing the pad 100. It can be easily fixed to the floor. That is, in the conventional case, a separate fixing device such as a tray or a pallet is used to prevent the pad from moving when the pet moves or excretes. However, in the case of the present invention, a separate fixing device is not used. The advantage is that the pad can be used conveniently even in places where the device is not located.

In addition, after using the pet pad 100 is separated from the bottom surface by folding the pad 100 by using the adhesive force of the adhesive portion 150 can not only reduce the volume of the pad 100, but also the pad 100 Can spread out to prevent the excretion from flowing out.

In addition, the release paper 160 is attached to the adhesive part 150 when the pet pad 100 is not in use, and is formed to have a larger area than the area of the adhesive part 150 to protect the adhesive part 150. When the pet pad 100 is to be used, the release paper 160 is separated from the adhesive part 150, and the pet pad 100 is adhered to a place such as a bottom surface.

Hereinafter, an experimental example of the present invention will be described.

The following method was used to test the deodorant effect.

The deodorization test method was a gas detection method (Gas Dectectin Method), and for this purpose, a 10 cm × 10 cm material was placed in a gas bag having a volume of 5 L and 3 L of a deodorization measurement gas was injected into the gas bag.

Deodorization measurement gas was to include 100ppm ammonia, 28ppm trimethylamine, 8ppm methyl mercaptan, and after 2 hours the amount of each gas absorbed was calculated through the following experimental formula.

% Absorption = ((Cb-Cs) / Cb) * 100

Here, Cb is the concentration of each gas (blank state) remaining in the gas bag after 2 hours, and Cs is the concentration of each gas (state material placed) remaining in the gas bag after 2 hours.

Absorption rates for the following five materials forming the absorber layer and the surge layer were measured.

Experimental Example 1: Material consisting of a TABCW (30gsm) surge layer without activated carbon

Experimental Example 2 Material consisting of a TABCW (30gsm) surge layer printed with activated carbon (4gsm)

-Experimental Example 3: Activated Carbon Is Not Printed and Is Made Of An SAP Sheet (120gsm) Absorption Layer Containing Citric Acid

Experimental Example 4-Activated Carbon Not Printed, A Material Made of a TABCW (30gsm) Surge Layer and an SAP Sheet (120gsm) Absorbing Layer Containing Citric Acid

Experimental Example 5-Activated Carbon (4gsm) Printed Material consisting of SAP Sheet (120gsm) Absorbing Layer Containing TABCW (30gsm) Surge Layer and Citric Acid

Deodorization test results for the above five materials are shown in the following table.

Experimental Example Experimental Example 2 Experimental Example 3 Experimental Example 4 Experimental Example 5 Whether activated carbon is included × ○ × × ○ Citric Acid Included × × ○ ○ ○ Deodorant ingredients - Activated carbon Citric acid Citric acid Activated Carbon / Citric Acid Trimethylamine 6.9 17.8 62.1 48.4 77.5 Methyl mercaptan 12.4 6.3 6.7 2.4 6 ammonia 5.1 9.1 98.2 99.4 99.0

In summary, when comparing the first and second experimental examples and the fourth and fifth experimental examples using materials in which only activated carbon is included, the deodorizing effect on trimethylamine is greatly improved. .

In addition, it can be seen that the third to fifth experimental examples using the SAP sheet containing citric acid have an excellent deodorizing effect on ammonia compared to the first and second experimental examples without using the SAP sheet.

In case of the fifth experimental example in which both the surge layer on which activated carbon was printed and the SAP sheet including stric acid were used as the absorption layer, absorption of odor-inducing factors such as trimethylamine, methyl mercaptan, ammonia and the like compared to other experimental examples And it can be confirmed that the deodorizing effect is improved as a whole.

Next, a pet pad product was formed using the above materials and the deodorizing effect was tested.

In the experimental example of the pet pad product according to the present invention, 18 gsm TBCW was used for the surface layer 110, 30 gsm TABCW coated with 4 gsm activated carbon was applied to the surge layer 140, and the absorbent layer 130 was used. A 120gsm SAP sheet containing citric acid is used, a 26gsm polyethylene film is used for the back layer 120, and a pattern such as a lattice pattern is formed with ink containing activated carbon (4gsm) on the TABCW surface of the surge layer 140. After printing, the amount of absorption into the liquid, the rate of absorption and the amount of rewet, and the rate of absorption of ammonia, methyl mercaptan and trimethylamine that cause odor were measured.

According to the present invention, the liquid absorption amount was 301 g, the liquid absorption rate was 19.4 sec, and the liquid backflow amount was 15.6 g.

In comparison, when the surge layer 140 was not used and / or the comparative product was not coated with activated carbon, the liquid absorption amount was 238 to 288 g, the liquid absorption rate was 27 to 36 sec, and the liquid backflow amount was 20 to 25 g. .

That is, when the surge layer 140 is provided according to the present invention, since the surge layer 140 disperses the liquid, it can be confirmed that the absorption rate is faster than that when the surge layer 140 is not provided. Since the 140 forms a space between the surface layer 110 and the absorbing layer 130 and serves as a barrier, it can be seen that the amount of backflow is greatly reduced. In addition, since the SAP sheet is used as the absorber layer 130, it can be seen that the amount of liquid absorption is also increased compared to conventional comparative products using a conventional absorbent.

And, as a result of the experiment on the deodorizing effect, in the case of the product according to the present invention, it can be seen that the removal rate of ammonia removal 98.8%, methyl mercaptan removal 82%, trimethylamine 12.5%.

On the other hand, the comparative products containing no activated carbon had ammonia removal rates of 96.3 to 98.2%, methyl mercaptan removal rates of 33.3 to 60.6%, and trimethylamine removal rates of 2.3 to 7.1%. That is, in the case of the comparative product using the SAP sheet, the removal rate of ammonia is relatively high, but the absorption rate for other odor-causing factors is lower than that of the pad according to the present invention.

That is, in the case of the pet pad 100 according to the present invention, the surface of the surge layer 140 contains a charcoal or activated carbon component, and the absorption layer 130 includes a monomolecular compound having a carboxyl group such as citric acid. It can be seen that the overall removal rate of odor generating factors such as ammonia, methyl mercaptan, and trimethylamine is greatly improved.

As described above, in the case of the pet pad according to the present invention, the absorption rate and the absorption amount of the liquid are increased by using the surge layer coated with activated carbon and the absorption layer composed of SAP sheets including carboxyl groups such as citric acid. Not only the amount of reflux decreases but also the absorption rate for the malodor-causing factor is improved, and the deodorizing effect is greatly increased.

While the invention has been shown and described with respect to particular embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as set forth in the claims below. I want to make it clear.
