PROBLEM TO BE SOLVED: To provide a fitting for a paper pipe and the paper pipe capable of being more safely used at a high speed by preventing the slip of the fitting and a chuck. SOLUTION: The fitting fitted to an end of the paper pipe comprises a cylindrical body; and a circular flange formed on one end of the body, and a concave-convex shape is continuously formed on at least a part of an inner peripheral surface of the body in an axial direction. Specifically, a step in a circumferential direction of the recession/projection shape is preferably formed at 0.1-1.5 mm. COPYRIGHT: (C)2010,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a connector unit for delivering a fluid which can be used by preventing the fluid from adhering on the inner face of a female connector when a male connector is pulled out from the female connector, the stuck fluid from dripping and staining the surrounding. SOLUTION: The male connector 3 is formed of a first male connector member 3A with an approximately cylindrical shape, and a second male connector member 3B having an inserting part 301 to be inserted into the first male connector member and a plug pressing part 302 connected with the front edge of the inserting part. An annular inner projecting part 20 is formed in the neighborhood of an opening 21a of one end of a through-hole 21 in the female connector 2, and an annular seal member 33 is provided on the front edge face of the first male connector member so as to be brought into fluid-tight contact with the projecting part. The plug pressing part can selectively take an actuating position for pushing a plug 4 through the opening of the front edge of the first male connector member by sliding the second male connector member in the axial direction and a waiting position which does not push the plug.

Abstract:
PROBLEM TO BE SOLVED: To provide a connecting system which has a stable engaging force between a plug and a male member when the male member is inserted/removed to/from a female member, the male member for the connecting system, and a closure member. SOLUTION: This connecting system is equipped with the female member 1, the plug 2 and the male member 3. In this case, the female member 1 has a conduit 11 penetrating in the axial direction, and is fixed in the opening of a container. The plug 2 is freely detachably engaged with the upper end part of the female member 1, and can close the upper end opening 16 of the conduit 11. The male member 3 has a pinching part 31 which pinches the outer periphery of the plug 2, and a rod-like part 33 which connects with the lower side of the pinching part 31, and is freely removably inserted in the conduit 11 of the female member 1 from the lower side. Then, in the rod-like part 33 of the male member 3, a fluid passage 35 extending from the lower end to the upper end is formed for the connecting system. COPYRIGHT: (C)2004,JPO

Abstract:
PROBLEM TO BE SOLVED: To provide a pouch plug wherein an easy and fast charging of contents into a pouch is performed, and an amount of dispensing of the contents is easily controlled. SOLUTION: A pouch plug 2 in accordance with the present invention comprises: a spout 3 having a male thread 31 at its upper part and having its lower part inserted into and fixed to an opening part 11 of the pouch 1; and a cap 4 having a female thread 41 engaged with the male thread at the upper part of the spout in a peripheral wall 4A. The plug 2 is further provided with a middle plug 5 having a nozzle part 5A of smaller diameter than that of the spout and fixed to the upper end of the spout. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a core capable of preventing unevenness from being formed in and on a sheet member itself by the end part of a sheet member to be wound up. SOLUTION: In this core 1, a layer comprising cells formed by sealing a gas in a membrane is formed on the surface layer part around which the sheet-like member 9 is wrapped. The surface layer part comprises a first layer 3 and a second layer 4 formed on a cylindrical base part 2. The first layer 3 is formed by winding and adhering an air cap R onto the base part. Namely, the cells formed by sealing the gas in the membrane of a plastic film forms the dome 7 of the air cap R. The second layer 4 is formed by winding and adhering, for example, a paper tape of 0.1 mm in thickness onto the first layer 3. COPYRIGHT: (C)2006,JPO&NCIPI
