PROBLEM TO BE SOLVED: To enhance the function of clogging prevention, at a spout, with film-like agglomerated substances and solids larger in size than those of the meshes of a filter as viewed from above. SOLUTION: The filter portion at the pour spout 1 is comprised of six rods 8a to 8f bridging the inner circumferential surface of an opening portion 7. Each of the six rods 8a to 8f belongs to one of the plurality of groups all having mutually different heights as viewed from the lateral face. That is, the heights of the respective six rods 8a to 8f disposed are all different. Furthermore, the six the rods 8a to 8f are disposed, in order from the top, with their positions being varied so that large voids are not generated, viewed from above. COPYRIGHT: (C)2005,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide a paper yarn tube, in which penetration of oil agent from an abutting part of paper tapes can be securely prevented, in which coating agent application quantity is reduced to restrict product cost, and in which the yarn releasing function is improved. SOLUTION: In this paper yarn tube 1, a paper tube is formed by spirally winding and laminating paper tapes 2A, 2B, and 2C to form a base part for winding yarn. Prescribed coating agent for preventing penetration of liquid agent contained in the yarn is applied to the paper tape 2A composing the outermost layer. Regarding a layer inside the outermost layer by a layer, the paper tapes 2A1 and 2A2 adjoining each other in the axial direction of the paper yarn tube 1 are set to apart from each other at their side edge parts to form a spiral gap. In the outermost layer, one of side edge parts of the paper tapes 2A adjoining each other in the axial direction is folded inward, and the side edge parts of the paper tapes adjoining each other are overlapped with each other, where a part of the overlapped part is held within a prescribed width 7.

PROBLEM TO BE SOLVED: To provide a molded product having excellent recyclability and a wide application range. SOLUTION: A lignophenol derivative is used as an interlayer 6 to prevent a substance which blocks defiberizing from permeating into the defiberizable molded product. The lignophenol derivative is separated from cellulose fibers in water during the defiberizing in a pulper and extracted with a solvent after the separation in the case of the molded product composed of, e.g. paper.

Abstract:
PROBLEM TO BE SOLVED: To solve the following problem: micro-fibril cellulose is bonded firmly by its hydrogen bond to increase its density and to make its molding difficult when dried due to the lack of thermoplasticity, the cellulose has to be cut to be worked into a cylinder, and energy is required for the micro-fibrillation of the cellulose to separate the recombined micro-fibrils from each other in order to reuse the cellulose. SOLUTION: A mixture 4 of the micro-fibril cellulose and water is extruded cylindrically by an extruder. An annular discharge opening is formed in a die 2. The mixture 4 discharged from the die 2 is led to a tip part 3 having an outside diameter equal to the outside diameter of a core tube to be applied on the core tube 5. The peripheral surface of the mixture 4 on the core tube 5 is faired by a fairing machine 6, and the mixture 4 is dried while the core tube 5 is covered with the mixture. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide a connection system for filling high-viscosity fluid at high speed and discharging powder without non-uniformity, and to provide a closed plug member. SOLUTION: The system includes: a female member 1 which has a pass-through guide passage 4 and constitutes the flow-in/out port of a vessel; a plug 2 which is integrally molded with the female member 1, freely removably engaged with one end part of the female member 1 existing at the inner side of the vessel, and clogs an opening in the vessel; a male member 3 which is provided with a head part 32 to be engaged with the plug 2 and a bar shape part 37 to be continued to the head part 32, and is inserted to the guide passage 4 of the female member 1, so as to be freely ejectable, from the other end part existing at the outer side of the vessel. A fluid passage 39 is formed by passing through a part from the end part of the bar shape part 37 in the male member to a place near the head part. The system includes a flexible connection member 20 for integrally molding the female member 1 with the plug 2. The flexible connection member 20 includes a cut part 16 formed to be smaller in cross section than a circumferential part. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide a connecting member with highly reliable enclosing property. SOLUTION: The connecting member consists of a female member, a male member 100 connected with this and a plug, and the female member has a main body with an axial cavity passing through the main body and extending from an inserting opening for the male member and a seat part extending on the peripheral edge of the cavity for the plug used for closing the cavity, and when the male member 100 is inserted into the cavity, the plug is released from the seat part. The male member 100 has an axial path 101 provided inside and a sealing member 110 acting as a check valve arranged inside of the axial path 101. This sealing member 110 has a flexible annular wall part 111 and a crosssectional wall 112 extending so as to cross the annular wall part 111 and is bent inside to form a path for the fluid.

Abstract:
PROBLEM TO BE SOLVED: To provide a method of manufacturing a paper core having high strength at an end thereof without generating deformation when carrying and fitting and removing it to/from a spindle and capable of maintaining the initial length and the inner and the outer diameters for a long time. SOLUTION: This paper core manufacturing method contains a cylindrical member manufacturing process for manufacturing a cylindrical member 1 formed of a main body 1b having the predetermined thickness and a thin part 1a provided in at least one end of the main body 1b so that the outer surface thereof is continued to the outer surface of the main body 1b and having a thickness thinner than that of the main body 1b, and an adhesive agent coating process for coating the inner surface of the thin part 1a with the adhesive agent to form an adhesive agent layer 2, and a folding process for folding the thin part 1a. The thin part 1a is folded several times to form a spiral part 1c, and the spiral part 1c is brought in contact with the main body end surface 1f, and the inner surface of the thin part 1a at a main body side part thereof is coated with the adhesive agent by the only predetermined length to prevent the generation of overlap of the adhesive agent layer 2 when forming the spiral part 1c.

Abstract:
PROBLEM TO BE SOLVED: To provide a paper core for a pressure sensitive adhesive film allowing to full use of the pressure sensitive adhesive film wound around the paper core for the pressure sensitive adhesive film to the last and easily recyclable as a paper resource after using it. SOLUTION: This paper core 1 for a pressure sensitive adhesive film is formed by winding a half glossed craft paper 3 as a face paper on a paper cylindrical base material formed of six layers of paper tube raw paper 2. A fluorine-based water repellent and oil repellent agents is adhered to the half glossed craft paper 3 at a degree to leave a clearance formed by entanglement of the paper fiber of the half glossed craft paper 3 (a surface of the face paper).
