摘要： A synthetic resin container has improved formability while preventing deformation of corner walls. The synthetic resin container includes a mouth that serves as a dispensing opening for contents, a body that is continuous with the mouth via a shoulder, and a bottom that closes a lower end of the body. The body includes a pair of main walls arranged so as to face each other with a gap therebetween, a pair of side walls arranged so as to face each other with a gap therebetween, and corner walls that couple respective ends in a circumferential direction of the main walls and the side walls. Each corner wall is provided with U-shaped ribs that are formed in a substantially U-shape within a surface of the corner wall and that are concave toward an inner side in a thickness direction of the corner wall.

摘要： A method of manufacturing a liquid container, in which, a nozzle unit includes a blow nozzle having a supply port and a spare supply tube having, at a lower end thereof, a spare supply port. The method includes: an air exhausting step of exhausting the air in the preform to the outside by supplying a liquid into the preform from the spare supply port located at a bottom portion of the preform; a liquid blow molding step of molding the preform into a liquid container by supplying a pressurized liquid from the supply port into the preform; and a headspace forming step of forming a headspace by exhausting the liquid from the inside of the liquid container.

摘要： A blow molding apparatus is configured to blow mold a preform into a container by supplying a pressurized incompressible fluid into the preform from a pressurized fluid supply unit. The blow molding apparatus includes: a drawing and discharging flow path connected to a drawing orifice; a fluid drawing source to apply drawing force to the drawing and discharging flow path, after blow molding is completed and after and/or while the blow nozzle is moved to a standby position, to draw the incompressible fluid adhering to the blow nozzle; and a pressurized gas supply source to supply a pressurized gas to the drawing and discharging flow path, after blow molding is completed and after a next preform is placed into the mold, to cause the incompressible fluid inside the drawing and discharging flow path to flow out toward the inside of the preform or toward the inside of a container.

摘要： A dispensing container capable of changing the ratio between the amounts of two kinds of contents to be dispensed, includes two container bodies, two pumps including two stems, an adjusting member configured to press the stems and to be rotatable about an axis extending in a substantially vertical direction, and a pressing head configured to, in response to a depressing operation, rotate about an axis extending in a substantially horizontal direction, to thereby depress the stems via the adjusting member. The adjusting member includes a plurality of pressing portions against which the stems are pressed, and when the adjusting member is rotated about the axis, a depressing stroke of the one of the plurality of pressing portions on the side of one of the stems becomes shorter, and a depressing stroke of the other one of the plurality of pressing portions on the side of the other stem becomes longer.

摘要： A blow molding device includes: a tubular-shaped nozzle; a tubular-shaped sealing body configured to be displaced between closing and opening positions; and a stretching rod surrounded by the sealing body. The sealing body includes a tubular wall, which has a drawing-in hole extending from one end to another end, the one end being open at a lower end of the tubular wall, and the other end being open at an outer circumferential surface of the tubular wall. The nozzle has a drawing-in path configured to communicate with the other end of the drawing-in hole when the sealing body is in the closing position. The blow molding device further includes a fluid drawing-in source configured to draw in the incompressive fluid from the drawing-in path.

摘要： A blow molding device includes a nozzle, a pressurized fluid supply source, a seal body, and a rod. The seal body includes a tubular wall. A communication depression extending from a lower end of the tubular wall to a communication port open on an outer circumferential surface of the tubular wall is provided in an inner circumferential surface of the seal body. A communication path is provided in the nozzle. The blow molding device further includes a fluid suction source configured to suck an incompressible fluid from the communication depression through the communication path and the communication port, and/or a pressurized gas supply source configured to supply a pressurized gas that blows off the incompressible fluid from the communication depression through the communication path and the communication port.

摘要： The present invention suppresses the amount of fluid pushed out from an injection needle when confirming whether air has been pushed out of the injection needle. Provided is a syringe that comprises: a cylinder 20; an injection needle 22; a needle base 24; an injection needle cover 26; and a plunger rod 28. The needle base 24 communicates between the inside of the cylinder 20 and the inside of the injection needle 22. The injection needle cover 26, when extended from a folded state, surrounds the injection needle 22. The injection needle cover 26 comprises an injection needle surrounding part. The injection needle surrounding part has at least one cutout 130 in a section facing the needle base 24 and covering the needle base, such that the needle base 24 can be identified from the outside.
