JP 54-18195 A (page 3-5, FIG. 1-5) International Publication No. 03/086250 Pamphlet (Page 6-12, Figure 1-5) JP 2004-130084 (page 10-14, FIG. 1-9)

  The flap for fixing the discharge port as described above can improve the operability when the discharge port is opened and closed, and also prevents the contact from the outside from directly acting on the hook-and-loop fastener engaging portion. It is possible to prevent the outlet from being fixed. However, in the conventional drainable excrement accommodation equipment having the flap fixing structure, there are the following problems.

  That is, in everyday life, clothes and other contact objects may be caught unexpectedly by the flap, and if such a catch occurs, the flap may be released at a stretch. As a result, there was a risk of excrement leakage. Of course, as in the configuration of Patent Document 3, by providing two fixing means, it is difficult for leakage of excrement from the discharge port, but the operation becomes complicated and the device is uncomfortable when it is bulky. There was a problem that it was easy to happen. Moreover, even if it is attempted to reduce the engagement of the contact by reducing the thickness of the flap engaging member, in this case, sufficient flap durability cannot be obtained, and the engagement is performed by repeated engagement operations. The strength was extremely lowered, and there was a risk of causing the flap to peel off. Since there are many elderly people who use a brace by constructing a stoma, the dexterity of the hand is also inferior, and a brace that can be handled more easily is desired. In addition, since such an appliance is used every day, it is less likely to feel uncomfortable at the time of wearing, and it is also desired that it be economical because it is replaced with a new one after being used for several days.

  In FIG. 1, the same material as that used in the related art can be used as the material constituting the face plate 1 and the bag body 2. For the support layer 3 of the face plate, a cloth such as a nonwoven fabric, a film, a foamed sheet or the like can be used. Examples of the material of the fabric include polyesters such as polyethylene terephthalate, polytrimethylene terephthalate, and polybutylene terephthalate; polyolefins such as polyethylene and polypropylene; polyamides such as nylon 6 and nylon 66; acrylics; polyvinyl alcohol; Vinylidene; and the like.

Examples of the material for the foam sheet include polyurethane, polyolefin, acrylic, chloroprene rubber, and silicone.

  A known hydrocolloid pressure-sensitive adhesive containing a hydrophilic substance that adsorbs or absorbs water can be used for the pressure-sensitive adhesive layer 4. As the material of the films 7 and 8 and the intermediate wall 13 of the bag body 2, the same film material that can be used for the support layer of the face plate can be selected. In particular, polyolefins or chlorinated products thereof, Those made of coalescent, polyvinyl chloride, or polyvinylidene chloride are preferred. The film may be used as a single layer or a composite film in which a plurality of films are laminated. As a material of the nonwoven fabric 9, the same material as the fabric material that can be used for the support layer of the face plate can be used. The two films 7 and 8 of the bag body 2 are formed so as to be integrated by welding or the like, including the cylindrical neck-like portion, at the outer peripheral edge.

  The auxiliary member 18 is a plate-like member that is harder than the bags 7 and 8, and the same material as the film material that can be used for the support layer of the face plate can be selected. In particular, in order to improve the ease of winding up the neck portion and the sealing performance of the discharge port, it is preferable that the auxiliary member 18 is installed over the entire width of the discharge port immediately above the discharge port. The notch 21 is for spreading the outlet by putting a finger on the end of the neck of the outlet, and in this embodiment, the notch 21 is provided on the auxiliary member 18 and the film 7 on which it is installed. If the finger is inserted from the notch portion 21 and the film 8 is pushed outward, the opening operability of the discharge port is further improved.

  The reference line 22 at the time of winding up the discharge port can be provided by printing or the like on the neck portion with an interval of the same length as the height of the auxiliary member 18. Since the reference line can be used to confirm the number and position of winding the discharge port, it becomes conscious of fixing the discharge port at an accurate position. As a result, it is possible to prevent excrement leakage often occurring when the discharge port is not fixed at the correct position.

  Next, the engaging members 19 and 20 will be described. The engaging members 19 and 20 are a combination of members having a pair of engaging means that can be engaged with each other. As the engaging means, for example, means such as a hook-and-loop fastener, a button, and an adhesive can be used. A hook-and-loop fastener is preferred. This hook-and-loop fastener engaging member includes a hook-shaped or mushroom (mushroom) -shaped pile (hereinafter referred to as a hook member) and a loop-shaped pile (hereinafter referred to as a loop member), or a protrusion and a corresponding protrusion. (Hereinafter referred to as a protruding member) can be used. In particular, the hook-and-loop fastener engaging member using the engagement between the hook member and the loop member has an advantage that the engaging operation is simple and can be formed as a soft member, so that there is little discomfort during use. On the other hand, the hook-and-loop fastener engaging member using the protruding members is formed of a relatively hard material so that the engagement is not disengaged. In order to ensure engagement, it is necessary to carefully press the entire surface of the hook-and-loop fastener engaging member with a finger, and there is a problem that the engaging operation becomes complicated, but the engaging strength is relatively high.

  The material of the hook member and the protrusion member of the hook-and-loop fastener engaging member can be selected from film materials that can be used for the support layer of the face plate, styrene-isoprene-styrene block copolymer (SIS), styrene-butadiene-styrene block. Copolymer (SBS), Styrene-ethylene / propylene-styrene block copolymer (SEPS), Styrene-ethylene / butylene-styrene block copolymer (SEBS), Styrene-ethylene / ethylene / propylene-styrene block copolymer (SEEPS), hydrogenated styrene-butadiene rubber (HSBR), styrene-ethylene / butylene-olefin crystal block copolymer (SEBC), olefin crystal-ethylene / butylene-olefin crystal block copolymer (CEBC), polycarbonate, polystyrene , Polyaceta It can be used Le like. These materials may be used alone or in combination of two or more. As the loop member of the hook-and-loop fastener engaging member, a sheet-like fiber structure such as a knitted fabric or a woven fabric having a loop on the surface can be used, and the material is the same as the fabric material that can be used for the support layer of the face plate. Things can be used.

The thickness of the hook member, loop member, or projection member is preferably 0.2 to 3.0 mm, and more preferably 0.2 to 1.0 mm. Further, the thickness in a state where the members are engaged with each other is preferably 0.3 to 4.0 mm, and more preferably 0.3 to 1.5 mm. These thicknesses are the thicknesses after applying a pressure of 0.7 kPa for 10 seconds. If the thickness is 0.2 mm or less, sufficient strength to withstand repeated peeling may not be obtained, and the member may be damaged or sufficient engagement strength may not be obtained. In addition, if the thickness of the member is 3.0 mm or more, clothes or other contact objects may be caught on the member, and the engagement may be easily released. Since it adheres and it becomes difficult to remove them, it may cause discomfort to the user. Further, the weight per unit area of the hook member, or projection member is preferably 50 to 400 g / m ^2, more preferably 80~300g / m ^2. Moreover, the weight of the Atari unit area of the loop member is preferably 20~800g / m ^2, more preferably 50 to 200 g / m ^2.

  The engagement strength between the hook member and the loop member, or the engagement strength between the projection member and the corresponding projection member is 1 to 30 times based on the engagement strength measurement method described later. It is preferable that it is the range of 0.5-10.0N / 50mm. When the same part is repeatedly engaged like the excrement container, the engaging part of the hook member or the protruding member is deformed or the raised part of the loop member is cut, and the engagement strength gradually decreases. However, if the engagement strength of 1.5 N / 50 mm or more is maintained, it is possible to prevent unexpected peeling of the engagement portion and maintain a stable engagement state. However, when opening the discharge port, the engagement strength is preferably 10.0 N / 50 mm or less so that it can be easily operated.

(Measuring method of engagement strength)
This measurement is performed in an environment of 23 ° C. First, the engagement surfaces of a pair of engagement members having a length of 100 mm and a width of 50 mm are overlapped, and a 2 kg roller is reciprocated twice from above to engage the engagement members to create a test piece. Next, the same side end of each engaging member of the test piece is attached to a grip of a tensile tester (Autograph AG-I, manufactured by Shimadzu Corporation), and is T-shaped in the length direction at a peeling speed of 300 mm / min. The maximum value of the peeling force at that time is defined as the engagement strength (N / 50 mm). The engagement strength is measured from the first engagement strength to be peeled first to the 30th engagement strength in which the same test piece is repeatedly peeled 30 times by the same operation.

In order to achieve the engagement strength while maintaining the thickness of the hook member, loop member, or protrusion member, it is preferable to have the following characteristics. That is, it is preferable that the height of the hook or protrusion in the hook member or the protrusion member is 0.2 to 1.0 mm, and the number of hooks or protrusions is 100 to 300 per 1 cm ² . Further, the height of the loop raising in the loop member is 0.5 to 2.0 mm, the number of the loop raising is 20 to 100 (preferably 40 to 60) per 25 mm in both the flow direction and the width direction, and the loop raising is formed. The fiber thickness is preferably 1 to 50 dtex. In particular, the engagement between the hook member and the loop member is preferable, and by specifying the hook or loop within the above range (the height and number of the hooks, and the height and number of the loop raising, the fiber thickness), Strain and breakage of the raised portion of the loop can be suppressed, and repeated decrease in engagement strength can be suppressed.

  Next, a method for using the engaging member will be described. In the embodiment of FIG. 1, the engagement members 19 and 20 are hook and loop fasteners used when the discharge port 17 is wound up upward and the discharge port is fixed in a closed state, as shown in FIG. As shown by e, the engaging members 19 and 20 are fixed by overlapping. In this case, the discharge port 17 is wound four times above the neck portion 16 starting from the auxiliary member 18 as shown in the series of wound states in FIGS. 2A to 2E, and the wound portion is fixed. The Thereby, the several surface of a winding-up part functions as a flat sealing surface, and it can prevent reliably that excrement leaks from a discharge port.

  In addition, since the engaging members 19 and 20 are formed so that the engaging members do not protrude from the outer peripheral edge of the bag body in a state where they are engaged with each other, clothes and other contact objects are formed on the engaging members. It is hard to get caught. Moreover, as shown in FIG. 2 f, the engaging member 19 is formed in a trapezoidal shape smaller than the engaging member 20, so that the engaging member 20 is engaged when the engaging members 19 and 20 are engaged with each other. Since a region that is not engaged is formed at both end portions of the lens, there is an advantage that the operability is good when the engagement is released by picking and operating the non-engaged region with a finger.

  Next, FIG. 3 will be described. FIG. 3 shows an embodiment different from that in FIG. 1 and shows a case where a hook-and-loop fastener as a flap-like engagement member 19 is attached to a film on the human body side. 3A is a partial front view, b is a partial cross-sectional view, and c is a partial rear view in a fixed state. The basic configuration and operational effects are the same as those of the embodiment of FIG. 1, but in the case of the embodiment of FIG. 3, the engagement member 19 closer to the discharge port is formed into a flap shape so that it is wound up. Since the engaging member 19 and the engaging member 20 can be naturally engaged with each other only by performing a certain operation, there is an advantage that the fixing operation can be performed with one hand. In the embodiment of FIG. 3, the discharge port 17 is wound up three times above the neck portion 16 with the auxiliary member 18 as a starting point, and the winding portion is fixed.

  In addition, as in FIG. 1, the engaging members 19 and 20 are formed so as not to protrude from the outer peripheral edge of the bag body when engaged, so that clothes and other contact objects are prevented from being caught on the engaging member. can do. Furthermore, since the peeling prevention means 23 formed from a plurality of concave and convex curved surfaces is provided on the outer peripheral edge of the engaging member 19, even if some kind of catching occurs on the engaging member and the flap-like engaging member starts to peel off, Since the inflection point of the concave and convex curved surface of the engaging member serves to stop the peeling, the entire engaging member can be prevented from being peeled off at once.
