Abstract: A fastener element for slide fasteners where the color and pattern change diversely with viewing angle. A coiled fastener element for slide fasteners that is to be furnished on a fastener tape, wherein the fastener element is provided with an engagement head, an upper leg, a lower leg, and inverting part for connecting the upper leg with the lower leg; a coating comprising at least one light-transmissive layer is formed on at least the upper leg; and the thickness of the light-permeable layer is formed so as to decrease gradually from the approximate top of the upper leg to the fastener tape side and so that the layer thickness near the top is at most about 50-1500 nm.

Abstract: An air/water-tight slide fastener has an end stop. The end stop has a flange portion extending therearoud. At least part of the flange is extensive enough to be integrally fixed to the opening edges of an opening formed in an article. Since the flange portion is firmly clamped by and between the air/water-tight fastener tape and the opening edges of the opening of the article; when the air/water-tight slide fastener is folded on itself; the excessive bending stresses exerted directly on the air/water-tight fastener tape is relaxed or mitigated. The air/water-tight fastener tape is thus prevented from being peeled off at that position.

Abstract: A product design apparatus (2) includes: a storage unit (20) for storing 3D CAD-based model data (21) of a plurality of products different from one another in terms of design and 2D product projection data (22) corresponding to the 3D CAD-based model data; a list display section (27) for displaying a list of the product projection data (22) on a screen; a 3D modeling program (25) for displaying the 3D CAD-based model data corresponding to the specified product projection data on the screen and for performing a shape modification through an operator's operation; and the storage unit (20) for storing designed data (24). Since a design can be performed based on the data that has been selected from the displayed data list, a product close to the customer's image can be designed in a short time, thereby shortening the time for determination of the design.

Abstract: A flexible container for liquid transport made of a flexible material includes a top face portion, a bottom face portion, and a peripheral face portion connecting the top face portion and the bottom face portion. An air tight, water resistant slide fastener is openably/closably mounted to the peripheral face portion of the container. A liquid stirring port is provided at the top face portion, and a liquid injecting and ejecting port are provided at a lower end of a rear face portion of the peripheral face portion. Container suspending pieces and bottom face portion fixing pieces are mounted at the top face portion of the container and at four corners of the bottom face portion. During washing, the container can be washed reliably and efficiently while the inside of the spread out container can be visually checked by efficiently utilizing the air tight, water resistant slide fastener, liquid stirring port, liquid injecting and ejecting port, and container suspending pieces, and bottom face port fixing pieces.

Abstract: The separable bottom end stop assembly has male and female members engageable with and releasable from each other in a front-to-back direction thereof. A slide plate of the male member has an engagement leg portion projected therefrom, while a sliding plate of the female member has an engagement hole. Sliding surfaces are respectively formed at peripheries of the engagement leg portion and the engagement hole of the slide plates. Each of the slide surfaces is formed with steep incline surfaces and a gentle incline surface. With the cam mechanism, when the male member and the female member are pressed from both surfaces thereof, an insert plate disposed at one of the male member and the female member is automatically guided to an inside of the slider held by a holding portion disposed at the other of the male member and the female member, which simultaneously causes the slider to start moving.

Abstract: An airtight waterproof slide fastener having a pair of fastener stringers in which a side edge of an airtight waterproof tape is bent so as to wrap and hold plurality of coupling elements having a coupling heads from a flange side thereof so as to form an engagement tooth holding portion having a substantially &OHgr;-shaped cross section and a peripheral face of that engagement tooth holding portion is nipped and fixed by means of a substantially U-shaped clamp element having of a pair of sheet-like nipping pieces. The clamp element is provided with stress-releasing portions between clamp elements for releasing tensile stress generated in a tape portion existing between side faces of the adjacent nipping pieces when the airtight waterproof tape is bent between the adjacent clamp elements, so as to secure air-tightness and not to be broken easily even if it is bent strongly in its longitudinal direction.

Abstract: In an automatic lock slider for a concealed slide fastener, a fastener-element guide post of a slider body has an upper groove receiving a locking lever and a lower groove slidably receiving a sliding end of a pivoting release member. A spring mounted in the guide post acts on an actuating arm of the locking lever to urge a locking pawl of the locking lever to normally project into a fastener-element guide channel of the slider body. An ornamental knob attached to the pivoting release member covers exposed part of the slider body. As the knob is pulled to pivotally move the release member, the locking pawl is retracted from the guide channel.

Abstract: A slider having a connection post which is not manufactured in a normal forming process such as a pressing process, can be certainly and firmly produced in a simple manufacturing process.A slider comprises a pair of wings which are individually formed. In one wing, a joining protrusion protrudes from a connecting post, and is provided with an engaging groove or plural engaging grooves. In the other wing, a joining hole is bored in the other connecting post. Therefore, the joining protrusion is interengaged with the joing hole. Then, a part of the material of the other wing is plastic-deformed and flows into the joining grooves to join the both wings integrally so as to provide a desired slider body.

Abstract: A novel and improved slider with a yoke for a slide fastener and a novel and improved method for attaching or joining the yoke to the slider body, which may be carried out in simple operation to be attractive in appearance and to provide firm combination between the yoke and the slider body.The front and rear support posts the slider body are respectively provided with locking groove and the contact faces of the yoke are also provided with bulged portions opposite to the locking grooves. In a preferred embodiment, after the support posts are covered with the yoke, a press force is applied to the bulged portion in the forging process to flow the material of the bulged portion into the locking groove so as to provide the firm combination.
