Description

The present invention relates to a toilet mat . More specifically, the present invention is a toilet mat that has a function of spreading urine scattered during use and deodorizing various unpleasant odors generated from urine by laying around a male urinal or Western-style urinal etc. About.

  Most of the malodorous component of excreted urine is ammonia. However, human urine suffering from some illness such as diabetes is mixed with several types of malodorous sources, which may be decomposed by microorganisms and become malodorous.

  Toilet floors are finished with ceramic tiles, concrete exposed finishes, rubber tiles, plastic tiles, flooring, etc., so the urine scattered on the floor diffuses and stays on the floor, even if the retained urine is completely Even if wiped off, the odor will fill the toilet. In order to prevent this, a means for quickly eliminating both urine scattered on the floor and malodor generated from the urine is required.

  Various types of toilet mats have been proposed as means for this purpose. The standard one is that a water-permeable surface mat and a non-water-permeable floor mat are joined in a bag shape, and a mixture comprising a superabsorbent resin (hydrogel) and a deodorant is placed between them. Is a type in which a urine-bad odor adsorbent filled in is inserted.

  The highly water-absorbent resin (hydrogel) and deodorant used in the above-described standard type toilet mat have a water absorption limit and a malodor adsorption limit, respectively. Therefore, if urine concentrates on a superabsorbent resin (hydrogel) and deodorant in a specific location, the water-absorbing effect and bad odor adsorption effect of the superabsorbent resin (hydrogel) and deodorant in that location will reach their limits. After that, each effect deteriorates. Therefore, the first requirement required for the above-described standard type toilet mat is that the urine scattered on the floor is quickly diffused in the longitudinal direction in the toilet mat to reduce the amount of urine per unit area as much as possible. The water is passed in the width direction to quickly eliminate both urine and malodor generated from the urine, and to maintain the water absorption effect and the malodor adsorption effect as much as possible.

  When the toilet mat is laid on the toilet floor, if there is a gap between the toilet mat and the floor of the toilet, the scattered urine will cause unevenness between the bottom layer of the toilet mat and the floor of the toilet. It enters into the gap to be formed and stays without being erased from urine and malodor generated from urine. Therefore, the second requirement for toilet mats is that they are flexible in all directions so that when they are laid on the floor of a toilet, they can fully follow any unevenness, so-called floor-trackability. Is that there is.

  Furthermore, the toilet mat is extremely important from the viewpoint of improving the hygiene of the toilet and beautifying the environment. However, there is a limit to the cost of toilets attached to various public facilities, public offices, public and private establishments, apartment houses, or detached houses. In particular, toilets in public facilities are used by an unspecified number of people, regardless of age, gender, healthy person, or disabled person. Therefore, in order to satisfy the demands of these diverse users, the cost of facilities is mainly low. The cost of processing unpleasant odors is limited. Therefore, the toilet mat is also an important requirement that material cost, manufacturing cost, etc. are low.

If a toilet mat that has exceeded the absorption limit of urine and odors and has deteriorated absorption capacity or a toilet mat that has been exposed to vomit is left on the toilet floor, the urine and vomiting will be lost. The bad odor generated from the thing stays inside the toilet mat, which is counterproductive. Therefore, the toilet mat is required to be laid easily so that it can be promptly replaced with a new one when necessary.

  Therefore, it is examined whether the conventionally proposed toilet mat meets the above requirements.

  Patent Document 1 describes a toilet deodorizing mat in which a deodorizing sheet composed of a special deodorant and a water-absorbing polymer is replaceably mounted between a surface mat and a waterproof sheet. [0006] of Patent Document 1 states that “the toilet deodorizing mat of the present invention is specifically configured as follows. Water-permeable flocked non-woven mat, artificial turf or plastic perforated board on the surface Or, place a spider or the like and insert the sheet underneath it, and then place a non-water-permeable plastic sheet underneath it and lay it around the toilet as a three-layer structure. " In addition, [0016] states that “the surface mat must be strong and cushioning because it can be stepped directly on a person's shoes. Further, it needs to be washed frequently with water, and therefore a pile mat made of synthetic resin. It should be something like artificial grass or artificial turf, and it must have a porous and liquid-permeable structure to allow spilled urine to pass through.

  The outermost layer material used in the toilet mat described in Patent Document 1 is artificial turf or a plastic hole board or a spider or the like, and has a considerable strength, for example, a toilet floor surface, for example, It cannot be said that it completely follows the unevenness formed by tile joints. In particular, in the case of a plastic hole board or kite child, a considerable gap is formed between the plastic hole board or kite child and the floor surface, and the scattered urine may stay in the gap. There is a defect.

  Furthermore, although the toilet mat described in Patent Document 1 is porous with water passage holes for allowing urine to flow in the width direction, urine scattered on the floor is quickly diffused in the longitudinal direction in the toilet mat. Therefore, it is not structured to reduce the amount of urine per unit area as much as possible and then allow water to flow in the width direction.

In Patent Document 2, a urine absorbing sheet storage space hollowed in a concave shape is provided at the tip of the outermost mat, a urine absorbing sheet is fitted therein, a urine absorbing sheet cover is placed on the urine absorbing sheet cover, and both sides thereof are covered. A floor mat for a urinal with a urine absorbing sheet marked with a foot position mark imitating a foot shape is described. The floor mat for urinals described in Patent Document 2 has a structure in which a urine absorbing sheet storage space is provided in a part of the urinal floor mat and the urine absorbing sheet is fitted therein.

In the case of the structure as in Patent Document 2, when urine is scattered in a portion other than the urine absorbing sheet storage space, it is impossible to absorb urine. In addition, the age group using urinals is wide from infants to adults, and further, from healthy people to disabled people. Therefore, even if a foot position mark imitating a foot shape is marked on both sides, it is not always necessary to stand at that position. Therefore, the floor mat for urinals described in Patent Document 2 does not satisfy the requirements for the toilet mat described above from these two points.

  The first problem to be solved by the invention is to quickly spread the urine scattered on the floor in the toilet mat in the longitudinal direction so as to reduce the amount of urine per unit area as much as possible, and then pass the water in the width direction. Both the urine and the odor generated from the urine are quickly erased, and the water absorption effect and the odor adsorption effect are maintained as long as possible.

  The second problem to be solved by the invention is that when laid on the floor surface of the toilet, it has flexibility in all directions so that it can fully follow any unevenness, so-called floor surface tracking. It is to let you.

  The third problem to be solved by the invention is to provide a toilet mat with reduced material costs, manufacturing costs and the like.

  The fourth problem to be solved by the present invention is to provide a toilet mat having laying ease that can be promptly replaced with a new one when necessary.

  The fifth problem to be solved by the invention is to provide a urine absorbent-deodorant composite structure that can be traded as a self-contained independent product.

  The above problems can be solved by means described in the following items.

1. Between the urine diffusion-penetrating carpet and the non-permeable backing material, which is composed of long fibers, has a water channel that diffuses urine in the longitudinal direction, and water-permeable holes that allow urine to penetrate in the width direction. A urine absorbent comprising a superabsorbent resin and a deodorant in which a superabsorbent resin and a deodorant are trapped on the surface of the support layer of a predetermined material, shape and dimensions, and the surface is further protected by a surface protective layer -A toilet mat in which a bag is bound by joining the urine diffusion-penetrating carpet and the non-permeable backing material with a deodorant composite structure interposed therebetween.

2. In the above item 1, in a state where an opening is provided in at least one of the urine diffusion-penetrating carpet and the non-permeable backing material, the bag is joined in a bag shape, and the urine absorbent-deodorant composite structure can be inserted and removed. Insert the toilet mat.

In the invention described in claim 1, the urine absorbent-deodorant composite structure comprising the superabsorbent resin and the deodorant is fixed to the surface of the support layer, and further the Compared with the prior art in which the superabsorbent resin and the deodorant are each dispersed in a free state because the surface is protected by the surface protective layer, the urine absorbent-deodorant composite comprising the superabsorbent resin and the deodorizer Since the superabsorbent resin and deodorant are securely fixed even while moving the structure, the urine absorption effect by the superabsorbent resin and the deodorizing effect by the deodorant are not unevenly distributed, and the water absorption-deodorizing efficiency But both As a result, the product becomes an object of commerce as an independent product, and also withstands storage and storage, thereby expanding the range of merchandising.

Also, a urine diffusion-penetration type carpet that is formed of long fibers, has a water channel that diffuses urine in the longitudinal direction of the water-permeable carpet, and has water-permeable holes that allow water to flow through in the width direction of the water-permeable carpet. Therefore, when the scattered urine reaches the surface of the carpet, it first diffuses in the longitudinal direction of the permeable carpet, and then absorbs urine inserted below the permeable holes formed in the width direction of the permeable carpet. The urine that has penetrated into the agent-deodorant composite structure is absorbed by the urine absorbent in a state of being diffused and diluted per unit volume, and the malodor generated from the urine is deodorized by the deodorant. Since the efficiency of the urine absorption-deodorization effect of the deodorant is good and the absorption-deodorization limit of each is expanded, the width of merchandising as a toilet mat is expanded.

  According to the invention described in claim 2, the urine absorbent-deodorant composite structure is taken in and out by joining in a bag shape with an opening provided in at least one of the urine diffusion-penetrating carpet or the water-impermeable backing material. Since it was inserted in a possible state, the effects exemplified below were successful.

  Lee. A urine comprising a permeable carpet and a non-permeable backing material joined in a bag shape with an opening provided at least on one side, and a bag provided with an opening, a superabsorbent resin and a deodorant Since the absorbent-deodorant composite structure is made independent of each other, the bag body is broken, or the urine absorption effect of the urine absorbent-deodorant composite structure composed of the superabsorbent resin and the deodorant and If the deodorizing effect deteriorates, it can be promptly replaced.

  B. A permeable carpet and a non-permeable backing material are joined in a bag-like shape with an opening provided on at least one side, and only a bag body provided with an opening is rented. The urine absorbent-deodorant composite composition consisting of odorant can be replaced periodically or as needed, thereby expanding the range of merchandising.

  Hereinafter, the best mode for carrying out the invention will be described as reference examples and examples.

FIG. The urine absorbent / deodorant composite structure 1 of the present invention in Reference Example 1 is 80 g of hot melt type adhesive 3 that melts at 80 ° C. on the surface of felt 2 having a thickness of 1 to 3 mm, for example, 150 g / m 2. Scattered in a string with a unit amount of / m2. The distance between the adhesives is preferably in the range of 5 to 10 mm, for example. In the case of 10 mm or more, the urine absorbent and deodorant described later easily move, so that the urine absorption and deodorant effects may be deteriorated. Next, a composite 4 composed of a urine absorbent and a deodorant is sprayed between the adhesives 3 and 3, and a nonwoven fabric 5 as a surface protective layer is coated and heated to 80 ° C. to heat the felt 2, the urine absorbent and the quencher. The composite agent 4 made of an odorant and the nonwoven fabric 5 as a surface protective layer are adhered and laminated to be integrated. Next, a thick paper 7 as a waterproofing and reinforcing layer having a thickness of 0.5 mm is bonded to the back surface of the felt 2 via a double-sided adhesive tape 6, and finally the thick paper 7 as a waterproofing and reinforcing layer and a double-sided adhesive. A tape 6, a felt 2, a composite agent 4 composed of a urine absorbent and a deodorant, and a nonwoven fabric 5 as a surface protective layer are bonded and integrated with each other to form a five-layer urine absorbent-deodorant composite structure. 1 was produced.
