摘要： A packaging machine for preparing sealed containers filled with contents each from a blank having a thermoplastic synthetic resin layer over each surface thereof. The container is recessed in the central portion of its bottom so as to seat stably. A bottom forming end portion of the blank fitted around a mandrel is folded flat and then pressed against the forward end surface of the mandrel by a press member with its press face to form the bottom of the container. The mandrel end surface defines a cavity for recessing the bottom central portion, and a projection complementary to the cavity is provided on the press face of the press member.

摘要： A blank feeder for a packaging machine for use with folded flat blanks unfoldable into tubes of square to rectangular cross section and having different lengths to form containers of different capacities. The feeder includes a magazine for containing a stack of flat container blanks. The magazine comprises an inclined frame defining a downward delivery opening and having opposite side members, an upper member and a lower member, a pair of blank unfolding pawls provided at the bottom surfaces of the upper and lower frame members and partly projecting into the opening, and a pair of movable blank supports reciprocatingly movable between an upper position above the frame and a lower position below the frame through the opening. The upper frame member is movable by a hydraulic cylinder longitudinally of the frame to adjust the distance between the unfolding pawls to the length of the blank. Blanks are supplied by an elevator to the movable blank supports in the upper position and then placed on fixed blank supports at the frame bottom by lowering the movable supports. When the movable supports are raised to the upper position to remove the remaining blanks from the magazine after packaging, the blanks are transferred from the movable supports onto movable guide rods brought to a fallen position from an upright position on the lower frame member.

摘要： A filling nozzle includes a vertical tubular nozzle body for receiving the liquid to be filled and supplied thereto forcibly and intermittently, and a rubber tube connected to the lower end of the nozzle body and having an opening at its lower end. The rubber tube is folded at required portions to constrict the opening. The opening is held closed by the elasticity of the rubber tube against gravity acting on the liquid within the nozzle body when the supply of the liquid is discontinued but is opened by the pressure of the liquid when the liquid is supplied to the nozzle body. The nozzle body is provided at its lower end with a tube holding portion having the rubber tube fitted thereover for holding the rubber tube in shape. The tube holding portion is externally in conformity with the inner surface of the rubber tube except at the folded portions.

摘要： An apparatus for filling a specified amount of liquid comprises a vertical tubular filling nozzle, a damper attached to the lower end of the filling nozzle and pivotally movable upward and downward, a vertical rod supported upwardly and downwardly movably inside the filling nozzle, a connecting member connecting the free end of the damper to the lower end of the vertical rod, a spring biasing the vertical rod upward to hold the damper closed against the gravity on the liquid within the nozzle, and a metering cylinder for feeding the liquid to the nozzle in the specified amount at a time to open the damper against the spring. An annular seat facing downward is formed on the inner surface of the nozzle approximately at the midportion of its height. A liquid channel blocking annular member is mounted on the vertical rod so as to come into contact with the seat simultaneously when or immediately before the damper is closed. The volume of liquid fed from the metering cylinder to the nozzle at a time is greater than the volume of liquid to be accommodated in the nozzle in the portion thereof under the blocking member.
