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.
An apparatus for producing containers made of paper-base laminate, the apparatus comprising: an intermittently drivable rotor 42 having radial mandrels 43 each adapted to support a tubular container blank of square to rectangular cross section as fitted therearound, the mandrels 43 being so arranged as to successively stop at each of processing stations I to VI including a pressure bonding station V, and a bottom bonding unit 48 disposed at the pressure bonding station V, each of the mandrels 43 having in a forward end face 54 thereof a groove 55 for forming the recess 36, the bottom bonding unit 48 comprising a bonding member 52 having a pressing face 56, the pressing face 56 being opposed to the forward end face 54 of the mandrel 43 as stopped at the pressure bonding station V, the pressing face 56 being provided with a ridge 57 corresponding to the groove 55.
A method and supporting apparatus for an executive phone patch is disclosed. An administrative assistant uses a first phone line to communicate with a first party, places first party on-hold, and establishes a connection with a second party. Once the second party is on the line, the two lines are connected together and the assistant is isolated from the conversation.
A packaging machine comprises a rotor 22 having radial mandrels 21 each adapted to carry a tubular blank 11 of square to rectangular cross section as fitted therearound and arranged to successively stop at a plurality of processing stations I to VIII, a group of devices 23 to 28 arranged respectively at the required stations among the processing stations I to VIII for folding and closing a container bottom forming end portion 14 of the blank 11 as fitted around the mandrel 21, and an air suction nozzle 31 for collecting extraneous matter is disposed at a required location along a path of movement of the mandrel.
A paper-base laminate container having a bottom closure formed with a recess. The recess has an inverted V-shaped cross section and extends across the bottom closure through the center thereof for positioning the container upright with good stability.
A pressure pad is provided for bottom sealing of a gable carton. The pressure pad cooperates with a mandrel which is urged into an opened-top gable carton for sealing the carton bottom. The pressure pad is provided with a sealing bar matrix which is disposed thereon to register with at least selected raw edges of paperboard material on the carton bottom. Each sealing bar functions to compress the fibrous paperboard material from which the carton is formed to render the raw edges less likely to absorb liquids that may be wicked from the raw edges to other locations in the carton. The carton formed by the pressure pad is characterized by reduced thickness raw edges adjacent the bottom.
