摘要： An apparatus for hot or warm filling comprising a compression machine configured to apply an axial compression force to a collapsible thermoplastic container for liquids. The compression machine includes a lower body having a surface designed to be a resting surface for the base of the container; at least one upper body designed to contact a portion of the container above the peripheral groove, so that the container can be held in an upright position by the at least one lower body and the at least one upper body; actuating means for actuating the at least one lower body and/or the at least one upper body in order to apply said axial compression force, acting along a direction parallel to the longitudinal axis of the container, in order to make the proximal straight side to come into contact with the distal straight side, thus reducing the internal volume of the container.

摘要： A blow mold for making PET containers comprising an inner surface corresponding to the outer outline of the container, on which there are one or more cavities or projections configured to make corresponding respective projections or cavities of the outer surface of the container, wherein the mold comprises one or more venting grooves along the edge delimiting said cavities or projections. A plurality of venting holes are possibly arranged along such grooves, as well as it is also possible for some venting holes to be arranged outside thereof. The width and depth of these are selected according to the wall thickness of the container to be blown to prevent that the deformation of the container during the blowing obstructs the venting grooves and leaves visible marks on the container.
