Embodiment Construction

[0045] figure 1 The shown installation comprises a plurality of stations through which a belt 10 of thermoplastic material is distributedly driven by drive means (not shown). Considered in turn along the direction of advance F of the strip advance, the facility comprises a heating station 14, a thermoforming station 16, a filling station 18 for filling thermoformed containers 50, and a station for closing the containers 50 by sealing a seal 22 over the opening of the containers. Closed station 20.

[0046] Naturally, the invention can also be applied to thermoformed containers of thermoplastic material other than in the form of continuous strips, for example in the form of individual wafers or tokens, from each of which one can be thermoformed. A container or set of containers. Furthermore, the facility may be one that only performs thermoforming without filling or closing the containers. Furthermore, said closure may be performed by different means than that shown at stati...

Abstract

The invention relates to a device comprising a mold block provided with at least one thermoforming chamber (28) having an inner surface (29); an axial opening (28A) through which a decoration can be wrapped around A type label (38) is inserted into the thermoforming chamber; and a movable bottom (40) opposite the opening. The bottom is movable into the end section (28A) of the thermoforming chamber (28) between a positioning high level and at least one thermoforming low level, and the apparatus has at least one groove combination comprising A fin (42) on the base (40) that engages a notch (44) in the inner surface of the end section (28B).

Description

technical field [0001] The present application relates to an apparatus for the manufacture of containers by thermoforming provided with a decorative wrap-around label or "stripe", the apparatus comprising a mold block having at least one thermoforming chamber having an inner surface, a shaft Move the end wall toward the opening and opposite the opening. Background technique [0002] Also known from documents FR 2340185, FR 2342145 and FR 2528349 are devices of the above-mentioned type having a label insert block of the circumferential type arranged on the other side of the mold block with respect to the axial opening, the purpose of which is to pass through the end wall of the thermoforming chamber. To insert a wrap-around label, the end wall is provided with an insertion slot or similar arrangement for this purpose. Those known devices have special mechanisms and are adapted to a special configuration so as to be able to transport wrap-around labels under the die block wit...
