Description

  The present invention relates to a portable toilet preventive device which is disposed on an inner bottom of a waste receiving bucket provided in a portable toilet to prevent the excreted waste from directly adhering to the toilet.

  People who need nursing care for reasons such as illness or age (hereinafter referred to as "cared people") are often unable to walk a long distance. Often, excretion is performed using an installed simple toilet (so-called portable toilet).

  This would be highly recommended from the point of promoting recovery of illness and human function, because autonomous excretion would be performed without using a diaper.

  However, disposal of the waste after excretion still required the cooperation of a caregiver. The disposal of such waste has been performed by taking out an internal bucket portion from a portable toilet and discarding it in the toilet of a general toilet or in a sewage inlet.

  This work was odor-intensive and burdensome both physically and mood. In addition, after disposal of the waste, a part of the waste often adheres to and remains in the above-mentioned bucket, which is a heavy burden in cleaning manually performed disinfection and sterilization of the bucket. Was.

  Incidentally, for the purpose of reducing the work load, for example, the invention of Patent Document 1 is disclosed. The present invention is a bucket-shaped disposable absorbent sheet disposed inside a toilet bowl, wherein the front side comprises a waterproof material, and the inner side comprises an absorbent material and a moisture coagulating material. In addition, gathers are provided at four places on the front side to facilitate arrangement on the inner surface of the simple toilet, and an adhesive tape for fixing is also provided.

This sheet can be placed on a simple toilet, and after excretion of the cared person, the sheet can be removed from the simple toilet together with the waste and disposed of. Will be done.
JP-A-10-248753 (pages 2-3, FIG. 3)

  However, the disposable absorbent sheet of Patent Literature 1 has a three-layer structure in which gathers are arranged at four locations, and furthermore, waterproof, moisture coagulation, and furthermore, an absorbent material is laminated, so that it has to be expensive. there were.

  Furthermore, since the disposable absorbent sheet covers almost the entire interior of the portable toilet, even if it is large, replacing it with each excretion also requires its running cost (cost of purchasing the product through continuous use). Not only is it large, but it is also cumbersome or unsanitary because it requires manual removal from the toilet for each excretion.

  Therefore, the present invention has been made in view of such a problem, and while suppressing manufacturing costs and running costs, there is provided a stain prevention device for a portable toilet which is easy to dispose and dispose of excreta at the mouth of the toilet. provide.

  In order to solve the above problems, the portable toilet bowl dirt preventive device according to the present invention is configured as follows.

  That is, a bottom portion (2) formed of a sheet material (1) having water resistance and shape retention for a predetermined time and adapted to an inner bottom portion (41a) of a bucket (41) inscribed in a portable toilet; And a side wall portion (3) rising upward from the outer peripheral edge (21) of the bottom portion (2) by a predetermined height. Then, the antifouling implement (A) configured as described above is placed on the bottom (41a) inside the bucket (41) of the excrement receiver provided inside the portable toilet (4) for use. The shape of the bottom portion (2) is preferably substantially oval. This shape fits well with the inner bottom (41a) of the bucket (41) inscribed in the portable toilet (4).

  The side wall portion (3) is formed so as to increase in diameter upward from the outer peripheral edge (21) of the bottom portion (2). The enlarged side wall (3) abuts against the inner wall surface (41b) of the bucket (41) such that the side wall (3) of the antifouling tool follows.

  The sheet material (1) is formed of a material that can be folded substantially flat, for example, a paper material. Thus, the preventive device is easy to store and transport without being bulky in the folded state.

  Further, it is preferable to perform a surface treatment (for example, a water-repellent coating treatment) on one or both surfaces of the sheet material (1) so as to prevent infiltration of moisture for a predetermined time.

  On the other hand, after a certain time, it is desirable to exhibit water solubility when disposing in a flush toilet.

  The antifouling device for a portable toilet according to the invention of the present application has the following effects because it is configured as described above.

  Because of the simple configuration in which the side wall is erected by expanding the diameter from the bottom part of the shape that fits into the inner bottom part of the bucket of the portable toilet, not only the manufacturing cost can be suppressed, but also the inner bottom part of the bucket and the inner wall of its peripheral part It is possible to cover and securely store dirt, and also to prevent partial attachment to the inner wall surface of the bucket.

  In addition, since the sheet material forming the stain prevention device is made of a material that can be folded substantially flat, not only the storage property is good, but also the handling property in the arrangement of the bucket on the inner bottom portion is good.

  Furthermore, since the sheet material has water resistance and shape retention for a predetermined time, and has been subjected to a surface treatment so as to have a waterproof property, it prevents the leakage of moisture of filth to the outside, and in a predetermined time until disposal. The storage of filth is possible.

  These effects prevent contaminants from adhering to the inside of the bucket of the portable toilet, and make a remarkable contribution to reducing the labor of a caregiver who has a large psychological burden such as cleaning and disinfecting the inside of the bucket.

  BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a best embodiment of a stain prevention device A (hereinafter, abbreviated as “stain prevention device”) for a portable toilet according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view showing a stain preventive device of the present embodiment, FIG. 2 is a plan view showing a state where the stain preventive device of the present embodiment is arranged on a portable toilet, and FIG. 3 is a stain preventive device of the present embodiment. It is a partially notched perspective view which shows the state which arranged the tool in the portable toilet.

  The antifouling tool A is made of a sheet material 1 having water resistance and shape retention for a predetermined time, and has a side wall portion 3 standing from an outer peripheral edge 21 of a bottom surface portion 2, and is configured in a so-called container shape. The antifouling tool A is disposed on the inner bottom 41 a of the bucket 41 of the portable toilet 4.

  The water resistance and the shape retention of the sheet material 1 for a predetermined period of time are not such that the sheet material 1 is immediately damaged when exposed to a certain amount of moisture. What is necessary is just to have shape. Furthermore, after storing the filth, the shape can be maintained without breakage or the like for a predetermined time while the filth is stored.

  The sheet material 1 is appropriately selected from, for example, a paper material, a synthetic resin material, and the like. In the present embodiment, a water-soluble and bendable paper material is used. Further, a material having a certain degree of rigidity is preferable. Due to the properties of the sheet material 1, the sheet material 1 has a certain shape retention property, and can be folded and substantially flat to store a large number of sheets. It is also possible to store a large number simply in a stack for a box-like or so-called caldera-like shape.

  The bottom surface portion 2 has a substantially oval shape (e.g., about 220 to 240 mm on the long diameter side and about 180 to 200 mm on the short diameter side) when viewed from above. This shape is substantially the same as the inner bottom 41 a of the bucket 41 of the portable toilet 4, and is a shape that conforms to the inner bottom 41 a of the bucket 41 as illustrated. For this reason, the disposition of the dirt prevention tool A on the inner bottom 41a of the bucket 41 is completed by simply placing the bucket. At the time of this arrangement, the caregiver can deploy the folded dirt preventive device A inside the bucket so as to avoid contact with the inner wall surface 41b and the hand.

  The side wall portion 3 is integrally erected at a predetermined height (for example, 50 to 70 mm) from the outer peripheral edge 21 of the substantially egg-shaped bottom portion 2. In addition, the side wall portion 3 is erected from the outer peripheral edge 21 so as to expand in diameter (for example, about 360 to 380 mm on the long side and about 300 to 320 mm on the short side). Therefore, the side wall portion 3 comes into contact with the inner wall surface 41b of the bucket 41 whose diameter is reduced in a mortar shape so as to follow the standing state. Then, in combination with the shape of the bottom surface portion 2, the inner bottom portion 41a of the bucket 41 and the inner wall surface 41b in the vicinity thereof are completely covered.

  In addition, the surface located inside the antifouling implement A formed in a container shape is subjected to a surface treatment (coating treatment) so as to maintain waterproofness for a predetermined time for the purpose of preventing moisture leakage of dirt. This surface treatment may be applied to the outer surface.

The antifouling device configured as described above is used as follows.
First, the caregiver arranges the dirt prevention tool A on the inner bottom 41a of the portable toilet 4 in advance so that the side wall 3 opens upward as shown in FIGS.

  When the care receiver excretes with the portable toilet 4, the dirt is received by the dirt preventive device A provided in the bucket 41 and stored in the dirt preventive device A.

  The caregiver removes the bucket 41 from the portable toilet 4 after excretion of the cared person, and a small amount of dirt between the dirt prevention tool A and the inner wall surface 41b of the bucket 41 in order to improve the sliding with the inner wall surface 41b of the bucket 41. The sheet material 1 of the dirt prevention tool A is made wet by pouring water.

  Next, the caregiver tilts the bucket 41 and discards the dirt preventive device A containing the dirt into a general flush toilet or the like so as to slide the dirt preventive device A together with the water poured in above. At this time, the outer surface of the dirt prevention tool A is to wash away the vicinity of the inner bottom 41a of the bucket 41, and it is also possible to wash away dirt attached to the upper side of the bucket 41 together. Since the discarded dirt preventive A has water solubility, it is sent to the septic tank and decomposed together with the dirt. Note that the caregiver may perform the sterilization and cleaning of the entire inner wall surface 41b of the bucket 41 as necessary after the above operation.

It is a perspective view which shows the dirt prevention tool of a present Example. It is a top view which shows the state which arrange | positioned the dirt prevention tool of a present Example in a portable toilet. It is a partially notched perspective view which shows the state which arrange | positioned the dirt prevention tool of a present Example in a portable toilet.
