Abstract: A mite trapping mat includes a mite attracting material; a film bag enclosing the mite attracting material; and a buffer element which forms a space inside the film bag. The film bag has a large number of small holes penetrating through the film, and the inside space of the film bag is a dark space. A mite trapping paper container includes: a mite attracting material; a buffer element containing the mite attracting material; and a flat paper box case in which the buffer element is stored. The box case has a large number of small holes penetrating from an outer surface to an inner surface, and an inside space of the box case is a dark space. At least any of a product name, a purpose of use, and a disclaimer is shown on a surface of the box case. The buffer element is made of at least any of cotton, cloth, nonwoven fabric, or grains which are larger than the small holes and is stuffed into the box case such that the box case is almost full.

Abstract: It is an object of the present invention to provide a water-absorbent pad that is made of impermeable cloth or sheet, that is capable of absorbing water when needed and that effectively cools and heats a human face, neck, head and the like. A cooling/heating water-absorbent pad, wherein a water-absorbent sheet made of a material containing water-absorbent polymer is inserted in a planate bag made of impermeable cloth having a closed periphery; the impermeable cloth and the water-absorbent sheet are stitched together such that the impermeable cloth and the water-absorbent sheet are divided into a plurality of areas in a planar view; and water is absorbed into the water-absorbent sheet through a channel formed at the stitched portion. In this moment, water is absorbed into the water-absorbent sheet only via holes made by the stitching and by a capillary action of a thread piercing through the water-absorbent sheet.

Abstract: A plastic bag 10D with a zipper 5 on an inner surface of an upper opening portion 14 of a bag body composed of plastic films 11 and 12, the zipper having a groove 7 and a protrusion 8 being engaging with and disengaging from each other. Both sides 13 and a bottom side 15 of the bag 10D are fused, and cut-offs 35 are made at both sides in the upper portion 14. With the zipper 5, the upper portion 14 can be opened and closed, and the upper portion 14 can be wide open. Further, at least one heat fusable plastic sheet may be put between the films 11 and 12, so that a plural number of chambers can be formed. Also, the films 11 and 12 may be fused along a vertical line, so that a plural number of chambers can be formed.

Abstract: A plastic fastener having a first segment 10A with a protrusion 12 formed on a first base 11, the protrusion 12 having a stopper hook on its end and having identical sections in a direction shown by arrow B, and a second segment 10B with a groove 16 formed on a second base 15, the groove being for nipping the hook of the protrusion 12 and having identical section in the direction shown by arrow B. The protrusion 12 and the groove 16 come into engagement with each other by pressures in directions shown by A and A? applied from respective back sides of the first base 11 and the second base 15, and the engagement is not canceled by forces in directions opposite to the directions A and A?. The engagement can be canceled only by sliding the protrusion 12 together with the first base 11 and the groove 16 together with the second base 15 in directions shown by arrow B and B?.
