  • the radius of rotation (pivotal movement) of the actuating arm 165 is approximately three times the radius of rotation (pivotal movement) of the lift arm 163.
  • the upper ears and lower ears of the container are heated by the heating device 28 immediately before the container is fed to the ear bonding device 29 .
  • the nozzles 125, 134 of the upper and lower heaters are indicated in dot-and-dash lines in FIG. 11.
  • the upper ear pressing member 141 is lowered with the rod 145 to press the portion of the container to be made into the bottom thereof, while the arm 154 lowered with the movable rod 143 moves the upper ends of the two levers 152 away from each other, thereby moving the lower ear pressing members 142 toward each other to press the portions to be made into opposite side walls of the container against each other. Consequently, the upper ears are bonded by the upper ear pressing member 141 under pressure to the portion providing the bottom of the container, and the lower ears are bonded by the respective lower pressing members 142 under pressure to the respective portions providing the side walls of the container.
  • the fluid pressure cylinder 166 Prior to the operation of the pressing member 141 and the pressing member 142, the fluid pressure cylinder 166 operates, rotating the actuating arm 165, pivot 164 and lift arm 163 counterclockwise in FIG. 11, whereby the forward end of the lift arm 163 is pushed up, causing the link 162 to push up the support member 143 into pressing contact with the lower surface of the chain 63.
  • the adjacent two holders 64 then positioned above the member 143 are pushed up along with the chain 63, and the rollers 76 of the pushed portion of the chain 63 are pressed against the upper walls of the guide rails 76 defining the respective guide grooves 77.
  • the pressing members 141, 142 When the pressing members 141, 142 are operated in this state, the pressure of these members 141, 142 is exerted on the adjacent holders 64 and received by the support member 143 through the chain 64.
  • the two adjacent transport blocks 71 concerned will flex and incline relative to each other by an amount corresponding to the play of the chain rollers 75 between the upper and lower walls defining the guide grooves 77 or to a clearance involved in each groove 77, possibly permitting the two adjacent holders 64 to flex relative to each other so that the space between the side walls 82 of these holders 64 would enlarge from portion to portion upward. It would then be impossible to subject the container supported by the adjacent holders 64 to a suitable pressure to create a faulty ear seal. However, the presence of the support member 143 obviates the likelihood of the adjacent holder 64 flexing and faulty sealing.
  • the container discharge device 30 comprises a large drive sprocket 171 and a small driven sprocket 172 which are disposed at one side of the terminal end of the container transport path, an endless chain 173 reeved around these two sprockets 171, 172, and a pusher pin 174 attached to the chain 173 so as to advance into the container transport path on the transport side of the path for the chain.

The distance the container C falls spontaneously can then be small, and the container C will not be damaged when received. With the travel of the receiving members 214, the container C is lowered while sliding on the bottom wall of the chute 211. Upon the members 214 receiving the container C reaching the lower end of the path of travel of the chains, the container so far received by the members 214 are transferred from the chute 211 onto the slide plate 212 and received by the stopper plate 213.
