Description

  The present invention relates to the technical field of a urine collection pad, and more specifically, to a urine collection pad that can prevent bleeding of urine that is environmentally friendly.

  The urine collecting pad is a pad having a function of adsorbing a liquid, and is widely used as a pet sheet or a nursing pad.

  The anti-bleeding property of the urine collecting pad is a performance reflected by the amount of urine that exudes from the urine collecting pad under a constant pressure condition for a certain period after the urine absorbing pad absorbs urine. If this amount is large, the product's exudation preventive property will be poor, and the smaller this amount, the better the product's exudation preventive property. When the urine absorbing pad is used as a care pad, if the amount of oozing increases, the user's skin will be severely damaged, and the comfort will be impaired due to the inferior feeling. When the urine collecting pad is used as a pet sheet, if the amount of oozing increases, the urine gets on the foot when stepped on by the pet, so that the room becomes dirty. For this reason, the bleeding prevention property is the most important index when judging the performance of the urine collecting pad.

JP 2004-016679 A

  In the conventional urine collection pad of the prior art, the core structure mainly has the following three types. Type 1 is a core structure product using a product formed by coating a mixture of wood pulp and a superabsorbent resin (hereinafter referred to as “SAP”) with two layers of tissue paper. As shown in FIG. 1, tissue paper absorbs water using the hollow structure of the fiber. Therefore, when pressure is applied after water absorption, the absorbed urine oozes out. And since the thickness of the tissue paper is only 0.05 mm, it is necessary to fill the core with a large amount of wood pulp so that the urine collection pad has a prescribed thickness and provides an accommodation space for SAP. is there. Thus, the consumption of wood resources is extremely large.

Type 2 is a core structure product using a product formed by coating SAP with tissue paper. Similar to Type 1, the water absorption of the tissue paper oozes out due to pressure, and because the product is thin due to insufficient thickness, the absorption performance is impaired.
Type 3 is a core structure product that does not use a coating material. Since the fluff pulp is not coated and is simply coated with the non-woven fabric of the product, the anti-bleeding property is further deteriorated, and the appearance is not regular because the core is not bound by the tissue paper.

  The production process of the core structure of a normal urine pad is as follows: unwinding lower tissue paper → pulverizing wood pulp → molding → filling SAP → coating → embossing → cutting. Since the raw material used for core production is untreated wood pulp having a burst strength of 1200, it cannot be crushed into fibers unless it is a defibrator that has a power of 35 KW or more when pulverized. The crushed fibers are mixed with air to form a fiber airflow, and the airflow is sucked in a negative pressure blower having a power of 75 KW or more in the molding chamber, so that the fibers are uniformly spread on the lower tissue paper. At the same time, small paper fibers are discharged by a negative pressure blower and become exhausted. The exhaust is processed by an ecology dust remover with a power of 45 KW. Then, it is filled with SAP, covered with upper tissue paper, squeezed with a squeeze mechanism, and then cut to form a core. At the time of product production, the power consumption of the core wood pulp processing stage is 155 kW, and the power for transportation transmission is 50 kW in total.

However, the prior art has many problems as follows.
1. Poor bleeding prevention property.
2. Consumption of wood pulp resources is large.
3. High power consumption during production.
4. Dust formed during grinding becomes environmental pollution.

The absorbent layer has, from top to bottom, a perforated film layer, a core layer, and a bottom adhesion layer. The perforated film layer is located between the surface layer and the core layer, and the lower adhesion layer is located between the core layer and the bottom layer.

  Furthermore, as an improvement of the present invention, the material of the perforated film layer is polyethylene, polypropylene, or a mixed material of polyethylene and polypropylene.

  Furthermore, as an improvement of the present invention, the perforated film layer has a thickness of 0.1 to 0.3 mm and a hole area ratio of 30 to 45%.

  Furthermore, as an improvement of the present invention, the perforated film layer is configured such that the shape of the established hole is funnel-shaped, and the large-diameter side of the funnel-shaped hole is directed to the surface layer.

  Furthermore, as an improvement of the present invention, the core layer is formed from a mixture of wood pulp and SAP material.

  Further, as an improvement of the present invention, an upper adhesion layer is provided between the core layer and the perforated film layer, and an SAP material is filled between the upper adhesion layer and the lower adhesion layer to form a core layer.

  Furthermore, as an improvement of the present invention, the surface layer is made of a material having a good touch and the bottom layer is made of a water-impermeable material.

  Further, as an improvement of the present invention, the material of the upper adhesion layer and the lower adhesion layer is both tissue paper.

Hereinafter, the present invention will be described in detail with reference to the drawings and a plurality of embodiments.
It is a schematic diagram of the urine collection pad by a prior art. It is a schematic diagram of the urine collection pad by 1st embodiment by this invention. It is a schematic diagram of the urine collection pad by 2nd embodiment by this invention.

  Hereinafter, in order to enable those skilled in the art to understand the concept and technology of the present invention completely accurately and deeply, according to the description of a plurality of embodiments, according to specific embodiments of the present invention, for example, the shape, structure, The mutual position and connection relationship of each part, the role and operation principle of each part, the manufacturing process and the usage method will be described in detail.

(First embodiment)
The urine absorption pad according to the first embodiment of the present invention is composed of a surface layer 1 formed of a material having a good touch such as a nonwoven fabric, an absorbent layer, and polyethylene (hereinafter referred to as “PE” hereinafter) in order from top to bottom. And a bottom layer 5 made of a water-impermeable material such as a waterproof film.

The absorbent layer has a perforated film layer 2, a core layer 3, and a lower adhesion layer 4 from top to bottom.
The perforated film layer 2 is located between the surface layer 1 and the core layer 3 and has a three-dimensional shape and is formed of a water-impermeable perforated material. For example, PE, polypropylene (hereinafter, “ PP ”) or a mixed material of PE and PP. The thickness of the perforated film layer 2 is preferably 0.1 to 0.3 mm. The aperture ratio of the holes in the perforated film layer 2 is 20 to 70%, preferably 30 to 45%. It is preferable that the formed hole has a funnel shape, and the large-diameter side of the funnel-shaped hole is configured to face the surface layer 1. As a result, the urine collection pad has a very high absorption rate. Since more water can be accumulated in the funnel-shaped hole, the anti-bleeding property is further improved.

  The core layer 3 may be formed of a conventional material in the prior art, and is preferably a mixture of wood pulp and SAP material (SAP). In this core layer 3, the SAP material has an excellent water absorption capability, and the wood pulp mainly adheres the SAP material as a carrier for adhering the SAP material, and flattens the core layer 3. Is for. Therefore, it can be ensured that the urine collecting pad has a uniform absorption performance and a flat appearance. Wood pulp also has a certain adsorption capacity.

  The lower adhesion layer 4 is located between the core layer 3 and the bottom layer 5. The lower adhesion layer 4 is made of tissue paper.

  A normal urine collection pad is formed by coating a mixture of wood pulp and SAP with tissue paper as a core structural material. The core is made of a mixture of wood pulp and SAP. Since both tissue paper and wood pulp are water-absorbing materials, urine tends to ooze out after the urine collecting pad absorbs urine.

  The urine collection pad according to the first embodiment uses the perforated film layer 2 as the surface layer structure material of the core layer 3, and the film itself such as PE is impermeable to water, so that a small amount of bleeding is caused only at the position where the hole is opened. It is. The opened hole is formed in a funnel shape so that the inner diameter increases toward the surface layer 1. Thereby, when the urine collecting pad according to the first embodiment is pressed, most of the moisture exuded from the wood pulp is accumulated in the funnel-shaped hole of the perforated film layer 2, so that a small amount of moisture from the surface layer 1. Will only ooze out. Under the same conditions, the amount of exudation of the core product provided with the perforated film layer 2 is 10% or less of the amount of exudation of the normal core product, and the urine collecting pad can be effectively prevented from exuding. .

  Further, in a normal urine collection pad, as shown in FIG. 1, the core layer 3 and the surface layer 1 are separated by tissue paper. In the urine collection pad according to the first embodiment, the thickness of the tissue paper is only 0.05 mm, preferably, and the thickness of the perforated film is 0.1 to 0.3 mm. Although it does not change, the amount of wood pulp used can be reduced. In other words, when the amount of wood pulp used is the same, the urine collection pad according to the first embodiment is thicker than a normal urine collection pad, and the use of the urine collection pad is also more comfortable.

(Second embodiment)
The urine collection pad according to the second embodiment has substantially the same structure as that of the first embodiment, but the absorbent layer has a perforated film layer 2, an upper adhesion layer 6, a core layer 3, and a lower adhesion, from top to bottom. Layer 4. The upper adhesion layer 6 and the lower adhesion layer 4 are both made of tissue paper, and are configured such that the SAP material is filled between the upper adhesion layer 6 and the lower adhesion layer 4 to become the core layer 3. .

  In the second embodiment, only the SAP material is used in the core layer 3 without using wood pulp, and the SAP material is covered with the upper adhesive layer 6 and the lower adhesive layer 4, thereby forming the basic shape of the core layer 3. Keep on. Further, urine is guided by the perforated film layer 2 and guided into the core layer 3 to realize absorption of urine.

  The absorption part of the core of a normal urine pad is a mixture of wood pulp and SAP material. Wood pulp guides and provides the necessary space for SAP, increases thickness, and makes urine pad use more comfortable. SAP plays a role in absorbing urine. A urine pad with a core of perforated film uses less or less wood pulp, and experiments show that the dose of wood pulp is about 0-45 grams per square meter. In the case of the same thickness, the product of the present invention can save 20 to 100% of wood pulp, so that the consumption of the urine pad for wood resources can be reduced. In other words, if the amount of wood pulp used is the same, the product of the present invention will be thicker and more comfortable when using a urine pad.

The production process of the absorbent layer core having the perforated film layer 2 is as follows: unwinding the lower tissue paper → filling the SAP → coating → embossing → cutting. Since the lower tissue paper is unwound and directly filled with SAP, coated with tissue paper and perforated material, and further coated and cut, the production power consumption of the product is The power for transportation transmission is only 50KW. When wood pulp is not used, the wood pulp is not required to be pulverized, so that 75% of the production power consumption of the urine pad can be reduced. While the power consumption of a normal urine collection pad is 0.105 kWh / m ² , the power consumption of the urine collection pad according to the second embodiment including a core with perforations is 0.0262 kWh / m ² .

  From the viewpoint of environmental protection, wood pulp defibration uses blade-type pulverization defibration, and 85% of fibers with a length of 0.5-4 mm and 15% of fibers with a length of 0.5 mm or less. Decomposes into a mixture with. Fibers having a length of less than 0.5 mm are sucked out by a wind having a negative pressure of 6 KPa or more at the time of molding, and after being processed by a dedicated facility, about 0.5% is still discharged as exhaust. The urine collecting pad according to the second embodiment is friendly to the environment because exhaust gas can be reduced by reducing or reducing the amount of wood pulp used. The raw material of wood pulp is primary forest wood, and the forest can be protected by reducing or reducing the amount of wood pulp used.

  The present invention has been exemplarily described above. However, of course, the above content does not limit the specific implementation of the present invention. Various insubstantial improvements made using the idea and technology of the present invention, or the application of the idea and technology of the present invention directly to other fields without improvement, are all within the protection scope of the present invention. It corresponds to. The protection scope of the present invention is in accordance with the scope of the utility model registration request.
