Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pet excrement disposal device used for treating excrement of pets kept indoors such as cats and dogs.

[0002]

Heretofore, artificial sand called "pet sand" has been used for excrement disposal of pets kept indoors. However, these artificial sands are quite expensive and cumbersome to dispose of. Therefore, recently, excrement disposal tools called “pet toilet seats” have been used instead. I have.

Here, the structure of this conventional pet excrement disposal device will be briefly described. A conventional pet excrement disposal device (hereinafter simply referred to as a conventional disposal device) is, for example, a rectangular sheet having a length of about 30 cm and a width of about 40 to 50 cm, and generally has a three-layer structure. That is, at the bottom, there is a backing material such as a polyethylene film, on which a layer of an absorber made of a mixture of ground pulp and polymer is provided. Further, the entire upper surface of the absorber layer is covered with a water-permeable surface material such as a non-woven fabric, thereby completing a conventional treatment tool.

[0004] Such a conventional treatment tool is laid in a waterproof tray that becomes a pet toilet. When the pet urinates (excretes) therein, the urine penetrates through the surface material and penetrates into the inside, and is quickly absorbed by the absorber. Therefore, after excretion, the used processing tool may be removed from the waterproof tray and discarded, and the cleaning-up is extremely simple.

[0005] However, the above-mentioned conventional processing tools have the following problems that require improvement. That is, in the conventional processing tool, urine discharged from the pet may leak from the edge, particularly from the edge along the longitudinal direction (in the width direction). This is because the distance between the edges along the longitudinal direction is shorter than the distance between the edges along the width direction, and therefore the absorption capacity in the width direction is much less than the absorption capacity in the longitudinal direction. It is.

[0006] Certainly, such excrement disposal device is laid in a waterproof tray so that urine may leak therefrom. However, it is unsanitary to leave the urine leaking and attached to the waterproof tray as it is,
May cause odor. Therefore, in the past, every time urine leaked from the processing tool, the waterproof tray had to be washed, which was very troublesome.

In view of such circumstances, a pet excrement disposal device for preventing urine leakage from the edge has been proposed. As one of them, there is one in which the thickness of the absorber on the edge side is extremely larger than that of other parts. If such a structure is employed, leakage of urine is less likely to occur than when the thickness of the absorber is uniform over the entire area. However, increasing the thickness of the absorber on the edge does not completely prevent urine leakage (because the part that cannot be absorbed still leaks). Most of all, most of the absorbent material required for increasing the thickness does not contribute to the absorption of urine until discarded, and the waste of the material becomes enormous.

On the other hand, as a pet excrement disposal device for preventing urine leakage from the edge, a flap is provided on the edge by projecting a part of a sheet constituting the excrement disposal device in the vertical direction. (See Japanese Patent Application No. 9-132006). In such a treatment tool, if the flap works as expected, urine leakage from the edge is almost completely suppressed. However, the flap formed as described above has a remarkable lack of stability, in other words, it is difficult to obtain a firm standing state. Often does not work. For this reason, it is impossible to completely prevent urine leakage from the edge.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a pet excrement disposal device which can effectively prevent the leakage of urine from the edge portion and which can eliminate waste of absorbent material, and which have excellent productivity. It is to provide a manufacturing method.

[0010]

SUMMARY OF THE INVENTION An object of the present invention is to provide a treatment tool used for treating pet excrement, which is provided with a sheet-shaped absorbent having a water-absorbing property, and which is disposed so as to cover one surface of the absorbent. A water-permeable sheet-shaped surface material, and a water-impermeable sheet-shaped back material disposed to cover the other surface side of the absorber, and a processing tool edge portion. A chord material for applying a contraction force along a longitudinal direction of the edge to the processing tool edge is provided, and the processing tool edge is configured to be erected by the action of the chord material. The problem is solved by a pet excrement disposal device characterized in that:

[0011] In particular, an object of the present invention is to provide a treatment tool used for treating excrement of pets, which is a sheet-shaped absorber having a water-absorbing property, and a water-permeable material disposed to cover one surface of the absorber. Comprising a sheet-like surface material having a property and a water-impermeable sheet-like back material disposed to cover the other surface side of the absorber, and formed by folding an end of the back material. A chord material for applying a contraction force along the longitudinal direction of the edge to the processing tool edge is disposed on the processed tool edge, and the processing tool edge is formed by the action of the chord material. The pet excrement disposal device is configured to stand upright.

Another object of the present invention is to provide a treatment tool used for treating pet excrement, wherein the treatment device is provided with a sheet-shaped absorbent having a water-absorbing property and is arranged to cover one surface of the absorbent. An end of the surface material, comprising a water-permeable sheet-like surface material and a water-impermeable sheet-like back material disposed to cover the other surface of the absorber. A chord that applies a contraction force along the longitudinal direction of the edge to the edge of the processing tool is disposed on an edge of the processing tool formed by folding the portion and the end of the back material together. The pet excrement disposal device is characterized in that the treatment device edge is configured to stand up by the action of the string material.

[0013] In a pet excrement disposal device in which a chord material is disposed on the edge of the treatment tool formed by folding both ends of the surface material and the back material together, the same chord material is attached to each other. It is preferable to be interposed between the end of the surface material to be joined and the end of the back material, so that a particularly good chord attachment state is obtained. However, the chord may not be interposed between the end of the surface material and the end of the back material, but may be fixed to one of them, particularly the non-joining surface (surface) of the surface material.

In the pet excrement disposal device of the present invention, in order to obtain a more stable standing state of the processing component edge, the processing component edge is located at a position between the chord material and the absorber. It is preferable that the portions that are bent and overlap by the bending are joined along the chord material.
By the way, a string material having elasticity (stretchability) is used as the above-mentioned string material, and a specific example thereof is a rubber string.

More specifically, as the surface material, a plurality of pores for imparting water permeability to the surface material are formed, and an annular protrusion having an inverted C-shaped cross section with a smaller inside diameter toward the tip is formed around the pores. It is preferable to use those obtained. That is, in the case where the front end side of the annular projection is in contact with the absorber and this surface material is used, the annular projection having an inverted C-shaped cross section functions as a check valve, so that it was once absorbed by the absorber. Urine reflux does not occur. That is, there is no problem that urine that has passed through the surface material returns.

On the contrary, an object to be solved is a method for manufacturing the above-described pet excrement disposal device, wherein the absorbent material is provided on a first raw material sheet serving as a back material, which is supplied as a continuous body. A step of forming a layer of the absorbing material, and the second raw material sheet, which is supplied as a continuous body and serves as a surface material, is coated with the first raw material sheet so as to cover the layer of the absorbing material formed in the A step. B step of laminating the first raw material sheet, an end of the first raw material sheet in the width direction,
Step C in which the end of the raw material sheet in the width direction is joined, and the string material having elasticity that is supplied as a continuous body is stretched, and the laminated body obtained in Step C is opposed to each other. A D step of arranging the string material at the edge portion to be cut, and an E step of cutting the laminated body having the string material disposed in the D step to a predetermined length and releasing the tension that has extended the string material. The problem is solved by a method for manufacturing a pet excrement disposal device characterized by comprising:

As described above, according to the present invention, a treatment tool which is provided with an absorber, a surface material, and a back material and is used for treating pet excrement is provided at an edge thereof along a longitudinal direction thereof. A chord is provided to apply the contracted force to the edge itself, and the edge is raised by the action of the chord. By the way, this upright edge serves as a barrier for urine to leak out of the processing tool, but if the upright state is unstable, it does not function effectively as a barrier and urine leaks. I can not suppress the delivery.

However, in the present invention, as described above, the contraction force of the chord material is applied to the edge to raise the chord. Therefore, the upright state of the edge is extremely firm and stable (because the edge is spontaneously in an upright state rather than in a sideways state under a contraction force). I do). As a result, leakage of urine from the processing tool edge is reliably suppressed. Further, in the pet excrement disposal device having the above configuration, the thickness of the absorber may be uniform over the entire area, and it is not necessary to make the edge side thicker as in the conventional product. Therefore, waste of the absorbing material forming the absorber is suppressed.

According to the present invention, when manufacturing the pet excrement disposal device, the elastic string material, which is supplied as a continuous body, is stretched in a stretched state and includes a surface material, an absorber, and a back material. At opposite edges of the
By cutting the laminated body on which the chord material is disposed to a predetermined length, the tension that has been used to extend the chord material is released, and the contraction force of the chord material is applied to the edge of the processing tool. I made it. That is, according to the manufacturing method of the present invention, the chord material can be arranged at the edge of the processing tool (arranged so that a contraction force acts on the edge) by such a very simple procedure. Therefore, it is possible to manufacture the excrement disposal tool very efficiently, particularly as a series of continuous operations, and high productivity can be realized.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a first embodiment of the present invention will be specifically described with reference to FIGS. FIG. 1 is an external view of a pet excrement disposal device according to the embodiment, FIG. 2 is a schematic cross-sectional view of the pet excrement disposal device according to the embodiment taken along line XX in FIG. 1, and FIG. Is a partially enlarged sectional view of a surface material constituting the pet excrement disposal device according to the present embodiment, and FIG. 4 is a schematic diagram of a production line of the pet excrement disposal device according to the present embodiment.

The pet excrement disposal device according to the first embodiment of the present invention (hereinafter referred to as the present disposal device) is laid in a waterproof tray serving as a pet toilet to remove pet excrement, especially urine. To process (ie to take urine)
What is used.

As shown in FIG. 2 in addition to FIG. 1, the present treatment tool generally has a sheet-like absorbent body 1 having water absorbency, a sheet-like surface material 2 having water permeability, and an impermeable sheet. And a sheet-shaped backing member 3 having the following. That is, the thin sheet-shaped surface material 2 covers the upper surface side (one surface side) of the thick sheet-shaped absorber 1, and the thin sheet-shaped back material 3 covers the lower surface side (other surface side) of the absorber 1. ) Are arranged respectively. The main part of this processing tool is
It is formed from the laminate having a three-layer structure thus obtained.

The absorber 1 among the above constituents is mainly a mixture of ground pulp and a water-absorbing polymer,
(The thickness is selected according to the kind and size of the target pet). To be precise,
The absorber 1 is obtained by sandwiching the mixture (amorphous absorbent material) between thin papers (not shown) and crushing the mixture to a predetermined thickness by pressing.

Next, the surface material 2 is made of a resin material such as polyethylene. The surface material 2 is a so-called net-like material in which countless pores are formed, and the presence of the countless pores imparts water permeability to the surface material 2. More specifically, as shown in FIG. 3, an annular protrusion 2b having an inverted C-shaped cross section is formed around the pores (indicated by 2a in FIG. 3), the inner diameter of which is smaller toward the tip end in contact with the absorber 1. ing.

However, this annular projection 2b is not a separate body,
Needless to say, it is integral with the other parts. That is, the annular projection 2b is formed simultaneously with the fine holes 2a during the punching press for forming the fine holes 2a. Incidentally, the annular projection 2b functions as a check valve, whereby the urine having once passed through the surface material 2 does not return. In the present embodiment, a net-like material having the above-described cross section is employed as the surface material 2.
Instead, a nonwoven fabric or the like may be used.

In this case, here, the surface material 2 and the absorber 1
Are bonded (heat-fused) at predetermined intervals to form the surface material 2
Does not separate from the absorber 1.

The back material 3 constituting the processing tool together with the absorber 1 and the surface material 2 is also made of a resin material such as polyethylene. However, since it is essential that the back material 3 has water impermeability, unlike the surface material 2 described above, there are no pores or the like. The back material 3 is also bonded (heat-fused) to the absorber 1 at a predetermined interval, so that the back material 3
It is regulated so that it does not peel off.

In the present embodiment, the chord material 4 extends along two longitudinally opposite edges of the processing tool M (which may be simply referred to as edges) formed by folding the ends of the back material 3. (See FIGS. 1 and 2). This string 4
Is made of a material having a required elasticity (stretchability), specifically, a rubber cord having a small diameter, and is adhered to the edge portion M, and thus to the backing material 3 over the entire length thereof. (The bonding may be discontinuous).

The chord 4 plays a role of applying a contraction force along the longitudinal direction of the edge portion M to the edge portion M. That is, the processing tool is configured such that the edge M spontaneously rises by the action of the chord material 4 (hereinafter, the rising portion is also referred to as a barrier). The chord 4 is bonded to the edge M in a stretched state. Therefore, as a matter of course, the entire length of the chord material 4, that is, the natural length is shorter than the entire length of the edge portion M (about 3/5 in this embodiment), and the chord material 4 always tries to return to the original length. . As a result, the string 4
As described above, the contraction force along the longitudinal direction of the edge portion M, in other words, the restoring force can be applied to the edge portion (barrier) M.

The longitudinal direction of the edge M on which the chords 4 are arranged coincides with the longitudinal direction of the processing tool. That is, the longitudinal direction here corresponds to the transport direction of the product (the connected body of the processing tools) on the production line. Further, in the present embodiment, for convenience in manufacturing, the chord material 4 is arranged only on two opposing edges M along the longitudinal direction of the processing tool, and a barrier for preventing urine leakage is formed there. Needless to say, similar chords may be arranged on two opposite edges along the width direction of the processing tool (however, since the frequency of urine leakage from the edge on this side is small, this edge is usually used). There is no barrier in the part).

In addition, in this embodiment, the processing tool edge M is
It is bent at a position between the chord material 4 and the absorber 1, and the overlapping portions are joined (heat-fused) along the chord material 4. This is to determine the base point of the portion to be raised in the edge M and to realize a more stable rising state of the edge (barrier) M.

Although the description will be repeated, in the present embodiment, the processing tool edge M is constituted by a part of the back material 3. That is, the width of the back material 3 and the surface material 2 (the length along the width direction) are different, and the former is naturally longer.
Therefore, the portion of the back member 3 outside the line to which the surface member 2 is joined is bent to form an edge portion (barrier) M on which the chord member 4 is arranged. Actually, the edge of the absorber 1 is wrapped around the end of the bent back material 3. On the other hand, at the edge along the width direction, the surface material 2 and the back material 3 are directly joined without sandwiching the absorber 1.

Next, a manufacturing procedure of the pet excrement disposal device, that is, a method of manufacturing the pet excrement disposal device according to the present embodiment (hereinafter referred to as the present manufacturing method) will be described with reference to FIG. .

FIG. 4 shows a schematic configuration of a production line for the pet excrement disposal tool. The production line generally includes a supply roll 1 for a first raw material sheet serving as a backing material.
1. Supplying means (absorbing material supply means) 12 for an absorbing material serving as an absorber, supply roll 13 for a second material sheet serving as a surface material, and a material sheet for joining the first material sheet and the second material sheet A joining means 14 is provided.

Subsequently, a supply reel (two in total) of a string material having elasticity is provided, and the string material is stacked on a laminate comprising a first material sheet, a second material sheet, and the like. Chord material bonding means 16 for bonding to the opposing edges of the laminate, edge shaping means 17 for bending and bonding the edges of the laminate to form it into a predetermined shape, and A cutting means 18 for cutting the sheet is provided.

As described before and after, the thin paper supply roll 1 for supplying the thin paper which plays a role of preventing the diffusion of the absorbent material is provided between the absorbent supply means 12 and the supply roll 13.
9 are provided. Although not specifically shown,
There is another thin paper supply roll. The thin paper supplied is then placed on the first raw material sheet and conveyed therewith. Therefore, in practice, the absorbing material is conveyed while resting on the thin paper, and covered with the thin paper supplied from the thin paper supply roll 19.

To manufacture the pet excrement disposal tool using this production line, first, the first raw material sheet is supplied from the supply roll 11 as a continuous body. And
An absorbent material layer serving as an absorber is formed on the first raw material sheet serving as the backing material by using the absorbing material supply means 12 (Step A). The absorbing material is formed by a pair of rollers 20a, which are located above and below the first raw material sheet.
It is crushed by 20b and becomes a sheet-like layer.

When the thin paper supplied from the thin paper supply roll 19 covers the layer of the absorbing material (after that, the crushing process is performed by the rollers 20a and 20b), the thin paper is supplied from the supply roll 13 as a continuous body. Then, a second raw material sheet serving as a surface material is laminated on the first raw material sheet. More precisely, this first raw material sheet is laminated so as to cover the layer of the absorbing material formed in the above-mentioned step A (step B).

When a laminate comprising the first raw material sheet, the layer of the absorbent material, and the second raw material sheet is obtained in this manner, the entire periphery thereof, particularly the end in the width direction of the first raw material sheet, is obtained. The part and the end in the width direction of the second raw material sheet are joined by a heat fusion method (step C). The ends in the longitudinal direction are also joined by heat attachment.

Subsequently, the chord material is supplied from the supply reel 15 as a continuous body. Then, using the chord material bonding means 16, this chord material is bonded to the opposing edges (ends of the second raw material sheet) of the laminate obtained in the above-mentioned C step (D step). However, at this time, tension is applied to the chord material, that is, the chord material is disposed at the edge of the laminate in an extended state. Thereafter, the laminate is sent to the edge shaping means 17. There, the edge is bent and further glued along the longitudinal direction to form a predetermined shape. That is, the edge has an L-shaped cross section.

Thereafter, the laminated body which has been completed through the above steps up to the arrangement of the chords is cut into a predetermined length by using the cutting means 18. At the same time, the tension for extending the string is released (step E). Thus, the pet excrement disposal tool F according to the present embodiment described above is obtained.

As described above, in the present embodiment, the pet excrement disposal device provided with the absorber 1, the surface material 2 and the back material 3 is shrunk along the longitudinal direction thereof at the edge M. A string member 4 for applying a force to the edge portion M itself is provided, and the structure is such that the edge portion M stands up by the action of the string member 4. By the way, the upright edge portion M serves as a barrier for urine that tends to leak from the processing tool. In the present embodiment, as described above, the shrinkage of the chord material 4 is caused by the edge portion (barrier) M. By applying force, it stands up.

Therefore, the upright state of the edge (barrier) M becomes extremely firm and stable. (In a situation where a contraction force is acting, the edge M is more spontaneously than a sideways state. To get upright). As a result, leakage of urine from the processing tool edge M is effectively suppressed. Furthermore, in the pet excrement disposal device having the above configuration, the thickness of the absorber 1 may be uniform over the entire area, and it is not necessary to make the edge side extremely thick unlike a conventional product. Therefore, waste of the absorbent material forming the absorber 1 is suppressed.

Further, in this manufacturing method, the elastic chord material 4 supplied as a continuous body is arranged in an extended state on the opposing edges of the laminate composed of the surface material 2, the absorber 1, and the back material 3. Then, by cutting the laminated body on which the string material 4 is disposed to a predetermined length, the tension that has been used to extend the string material 4 is released, and the string material is attached to the edge of the processing tool. 4 was applied. That is, according to this manufacturing method, the chord material 4 can be arranged at the edge of the processing tool (arranged so that a contraction force is applied to the edge) by such a very simple procedure. Therefore, it is possible to manufacture the pet excrement disposal tool extremely efficiently, particularly as a series of sequential operations, and high productivity can be realized.

Next, a second embodiment of the present invention will be described.
This will be described with reference to FIG. FIG. 5 is an enlarged sectional view of a main part of the pet excrement disposal device according to the present embodiment. Incidentally, the structure and function of the main body portion, the effect to be achieved, and further the technical idea of the pet excrement disposal device according to the present embodiment are the same as those of the first embodiment (third embodiment described later). The same applies to Therefore, the following description focuses on the differences from the first embodiment.

The pet excrement disposal device according to the present embodiment (hereinafter, again referred to as the present disposal device) is also provided so as to cover the sheet-shaped absorbent 21 having water absorbency and the upper surface side of the absorbent 21. In addition, a sheet-like surface member 22 having water permeability and a sheet-like back member 23 having water impermeability disposed to cover the lower surface side of the absorber 21 are provided.

In the present treatment tool, the chord material 24 for applying a contraction force along the longitudinal direction of the edge to the same edge is provided.
The disposition position is the same as in the first embodiment, and the cross section is L
