Abstract: An extruding mechanism for a tubular bag and a method of extruding the contents of a tubular bag are provided, by which a sealing material or the like is extruded and discharged from a tubular bag with an extruding gun for a cartridge container, and which reduces the amount of discarded waste, thereby serving as one solution to environmental problems. The extruding mechanism includes an extruding gun having a holding base, and a stationary holding plate disposed on a front end portion of the holding base. The holding plate is provided with a notched portion opened upward. An extruding rod is equipped at its leading end with a pressing plate. A cylindrical member having a cylinder body is set on the holding base and accommodates the tubular bag and is opened at both ends, and a piston body is inserted into the cylinder body.

Abstract: There is provided a container for display and storage comprising a body rectangular base sheet and a lid rectangular base sheet connected in a double spread sheet (or folded) condition by a folding line along the longitudinal direction. The rectangular base sheet on the body side is provided with a transparent cover in which an article can be contained and an opening is provided in the reverse face through which the article can be freely taken out and put in.

Abstract: This invention provides a method which is capable of strong and rapid-curing adhesion of various kinds of components including plastic components. Especially, this method can be industrially utilized with high efficiency in in-line adhesion assembly of various kinds of components, for example, plastic components, such as adhesion assembly of optical disks by adhering plastic plates together. Namely, this method comprises the steps of forming a face for effecting curing acceleration for an anaerobic curing adhesive on one or both of the adhering surfaces of the components to be adhered, coating the anaerobic curing adhesive on one or both of the adhering surfaces of the components, and laying one adhering surface on the other adhering surface of the components.

Abstract: A two-part room temperature curable composition comprising liquid part A containing an organic polymer having reactive silicon groups, and a promoter for the polymerization of a radically-polymerizable monomer as essential components; and liquid part B containing the radically-polymerizable monomer, an initiator for the polymerization of the radically-polymerizable monomer, and an accelerator for the curing of the organic polymer having reactive silicon groups as essential components. The two-part composition can be mixed together at room temperature and has the property of curing rapidly to produce a product with a flexibility equivalent to rubber materials. Thus, when used as a flexible protective coating, potting material, sealing agent or adhesive, this product can reduce working time while guaranteeing high reliability and can prevent pollution of the working environment.

Abstract: A tool for squeezing out a high-viscosity liquid from a flexible plastic tube container includes a spool having a slot in which the bottom of the tube container is received and locked, and a container holder having a pair of opposed bearing portions frictionally and rotatably supporting thereon a body of the spool, and a pair of opposed engagement portions engageable with a body of the tube container as the tube container is wound on the spool body from the bottom thereof. When a rotational force or torque on the spool is released, the spool is urged to rotate in the reverse direction by a resilient force stored in a portion of the flexible plastic tube container wound on the spool body. However, partly due to a friction acting between the spool body and the bearing portions, and partly due to the engagement between one of the engagement portions and the tube container, the spool is held immovable relative to the container holder against the resilient force of the tube container.

Abstract: A shape-holding composite pressure sensitive plate comprising a substrate of organic high-polymer, a metal sheet attached to one surface of the substrate and adapted to be bent by hand and to hold, in free form, its shape, a pressure sensitive adhesive applied to the other surface of the substrate, and a release liner peelably attached to the other surface of the substrate via the pressure sensitive adhesive.

Abstract: A method for bonding two objects by means of the following two adhesives:(A) a moisture-inducible room temperature anion polymerization curing adhesive composed essentially of at least one anion polymerizable compound selected from the group consisting of an .alpha.-cyanoacrylate compound, and a 1,1-disubstituted diene compound;and(B) a room temperature self-curing adhesive containing from 0.05 to 50% by weight of an anion polymerization accelerator, said self-curing adhesive being selected from the group consisting of (1) a room temperature moisture-curing adhesive, (2) a room temperature curing two-part type epoxy resin adhesive, and (3) a room temperature curing synthetic resin aqueous emulsion adhesive, which comprises applying said two adhesives (A) and (B) at the bonding interface of the objects so that they do not contact each other and pressing the objects to each other to bring the two adhesives in contact with each other.

Abstract: A cardboard container with anti-slip property is disclosed. It has a synthetic resin layer formed of thermoplastic synthetic resin fine hollow particles of 5 to 50 microns in diameter containing one or more of an inert gas, an active gas, a nonvolatile liquid and a volatile liquid coupled by a synthetic resin component exhibiting an action of a binder. The synthetic resin layer is formed on the outer surface of at least one of bottom and upper walls of the container on the entire surface or a portion of the surface as a spot, a lattice or a stripe. Thus, particular means are not necessary to handle the cardboard container such as packing with a film or binding with bands after stacking a plurality of containers. The anti-slipping effect remains even after the stacked containers are sorted and transferred.

Abstract: A push rod is forwarded to extrude viscous material in a tubular container from the nozzle. When the extrusion of viscous material is finished, i.e. stopping the forward operation of the push rod, the push rod is allowed to go back by a force resulted by expansion of air unavoidably contained, in the tubular container thereby absorbing expansion of air so as to prevent unwanted discharge of the viscous material due to an inner pressure of the tubular container.

Abstract: A container for storing a moisture-sensitive material which comprises a fillable space behind the moisture-sensitive material, which has contained therein a water-reactive, highly volatile silane, alkyl titanate or isocyanate which, upon reaction with water, produces a low-viscosity material which is water repellant. The water-reactive compound prevents contact of moisture with the moisture-sensitive material while it is in the container.
