Abstract: The containers are thermoformed in groups, filled, and closed. Then, the containers are separated, and placed adjacent to one another in such a manner that segments of their respective rims face each other and define between them a line of separation. On said line, at least one spot weld is formed that forms a breakable connection between the facing rim segments.

Abstract: A device for thermoforming containers, the device having mold blocks mounted to move in translation. An example embodiment may include at least first and second analogous mold blocks, a counter-mold, means for causing a thermoplastic material to advance along an advance axis, and two labeling blocks. The mold blocks can be moved in a first movement between a thermoforming level and a disengagement level. The mold blocks can also be moved in a second movement along an axis transverse to the advance axis so as to place each mold facing in succession the counter-mold and one of the labeling blocks.

Abstract: The containers are thermoformed at a thermoforming station from blanks cut out from a sheet of thermoplastic material. Before thermoforming the containers, at least some blank zones in the sheet are heated, the hot blanks are cut out from the heated zones and the hot blanks are conveyed to the thermoforming station.

Abstract: The invention relates to a method of manufacture of receptacles by thermoforming and the placing of decorative banderols on these receptacles, in which a first mould block is provided, which may include at least one thermoforming chamber and which is capable of tilting between a working position for the thermoforming of the receptacles and a tilted position for the introduction of a banderol into the thermoforming chamber before the thermoforming of a receptacle in the chamber. The invention is characterized in that a second mould block is provided analogous to the first mould block and in that while one of the mould blocks is in the working position for the thermoforming of a receptacle in the thermoforming chamber of this mould block the other mould block is in the tilted position for the introduction of a decorative banderol into its thermoforming chamber before the thermoforming of another receptacle in the chamber.

Abstract: The device for thermoforming an object presenting an undercut portion. The device may include a thermoforming mold having a base portion and at least two undercut-forming portions in the vicinity of an end; a countermold; and a moving thermoforming piston. The device further may include holding means suitable for holding the rim of the object relative to the countermold, and, in order to unmold the object, said portions of the mold and the holding means are suitable for being controlled in a sequence in which the undercut-forming portions are moved apart, the holding means are active and hold the object against the countermold, and at least the base portion of the mold is spaced apart from the countermold while the holding means are active.

Abstract: The installation for manufacturing objects such as receptacles by thermoforming pellets of thermoplastic material includes conveyor means for conveying the pellets through the various stations in the installation, said stations including a heating station and a thermoforming station. The conveyor means comprise conveyor elements (46) defining cells (48) which are open upwards and downwards, and each of which is suitable for containing one pellet (12) while the entire top and bottom faces of the pellet remain unobstructed, means for depositing the pellets in the cells, drive means for driving the conveyor elements through the heating station, and transfer means (20) for transferring the heated pellets to the thermoforming station. The heating station includes bottom heater means (52) that co-operate with a support for the pellets while said conveyor elements are being driven through the heating station.

Abstract: Blanks (12) of thermoplastic material are heated, and a thermoforming step is performed in which the heated blanks are deformed plastically by stretching. Before the thermoforming step, a die-punching step is performed in which the peripheral regions of the blanks are deformed by die-punching while the material of the blanks is held captive on the outside. The installation includes heater means (16) for heating said blanks, thermoforming means (24), and a die-punching tool (26, 28) suitable for deforming the peripheral regions of the blanks before they are thermoformed.
