Abstract: The facility comprises a plurality of processing stations (14A, 14B, 14C, 16, 18, 20, 20, 22, 24) for producing containers from a thermoplastic substrate. The facility comprises a plurality of basic conveyors (30) that cooperate with a travel track (32), for the purpose of conveying the sheets to the processing stations, the respective movements of the basic conveyors being controlled according to respective movement control commands generated by a control unit (ECU).

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: 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 container comprises a container body and a label placed on said body. The label has a window through which there can be seen decoration on the body of the container. In the method, before affixing the label on the body, a window is cut out in the label, and then the label is affixed in such a manner that a portion of the body is visible through said window, and decoration is made on said portion of the body of the container.

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.

Abstract: Receptacles are thermoformed in a strip of thermoplastic material, filled with a substance, and covered by capsules formed in a capsule strip. Prior to applying the capsule strip onto the thermoplastic strip, a preliminary cut is made for each receptacle in a station through the thermoplastic strip, thereby defining a portion of the outline of the edge of the receptacle. While the receptacles and their capsules are being cut out from the strips, a through cut is made for each receptacle in a station, the through cut passing through the thermoplastic strip and the capsule strip over a portion of the remainder of the outline of the receptacle, and a complementary cut is formed which passes through the capsule strip alone, which is connected to the through cut, and which, for each receptacle, defines a portion of the capsule strip that forms a pull tab.

Abstract: Receptacles (1) are thermoformed in a strip of thermoplastic material (10), filled with a substance (17), and covered by capsules formed in a capsule strip (22). Prior to applying the capsule strip (22) onto the thermoplastic strip (10), a preliminary cut is made for each receptacle in a station (22) through the thermoplastic strip (10), thereby defining a portion of the outline of the edge of the receptacle. While the receptacles (1) and their capsules (42) are being cut out from the strips, a through cut (37) is made for each receptacle in a station (28), the through cut passing through the thermoplastic strip (10) and the capsule strip (22) over a portion of the remainder of the outline of the receptacle, and a complementary cut is formed which passes through the capsule strip (22) alone, which is connected to the through cut, and which, for each receptacle, defines a portion of the capsule strip that forms a pull tab.

Abstract: The method and the installation of the invention enable re-entrant receptacles to be thermoformed, filled, and closed, the rim of each receptacle having a diameter that is smaller than the diameter of its body. Prior to thermoforming a row of receptacles, preliminary cuts separated by attachment points are made in a transverse stripe of the strip of the thermoplastic strip that is to be used for thermoforming in a subsequent cycle, and for each receptacle that is to be thermoformed, the cuts define practically the entire final periphery of the rim of said receptacle, the attachment points being broken when the receptacles are separated in a subsequent cycle after the filled receptacles have been closed.

Abstract: An apparatus and method for making a receptacle from a generally flat thermoplastic blank has an upstream conveyor extending along a path in a transport direction through a loading station, a heating station downstream of the loading station, and a forming station downstream from the heating station. The conveyor has a plurality of supports forming a plurality of respective throughgoing apertures spaced apart in the direction. A supply at the loading station positions a respective blank atop each of the apertures of the conveyor with a central region of each blank exposed through the respective aperture and a periphery of each blank engaging and supported by the respective support A drive connected to the conveyor advances it and the blanks carried on it step-wise through the heating and forming stations. At the heating station at least the central region of each blank is heated to a softening point.
