The invention is generally directed to sports bottles and other articles produced by blow molding from polymeric materials containing isosorbide having glass transition temperatures ranging from 90 C. to 130 C., as well as to processes for producing them. These articles can be exposed to water at high temperatures and can be produced by using a suitable combination of a stretch ratio of less than 3 and a preform temperature at least 20 C. greater than the glass transition temperature (Tg) of the polymeric material.

Apparatus and method for producing plastic bottles. An apparatus for producing plastic bottles includes a blow molding machine to receive and to stretch blow mold preforms into bottles. The apparatus includes a modular machine to receive the bottles from the blow molding machine and to at least one of label or print on the bottles. The modular machine includes a first unit to perform a first task. The first unit is replaceable with a second unit. The second unit is to perform a second task different from the first task. The blow molding machine is bloc-synchronized with the modular machine to space the blow molding machine a distance from the modular machine.

The invention relates to a heating device (H) for the thermal conditioning of preforms (1) made of a thermoplastic material at a temperature profile that is suitable for a blow molding and a blow molding machine (B) having a heating device (H) of this type. The heating device (H) has multiple heating units (30, 30) arranged behind one another along a heating section (24) and transport means (33) for transporting the preforms (1) on a transport path (55) along the heating section (24) and along the heating units (30, 30). The transport means (33) are connected in a chain-like manner to form a closed continuous transport chain (50) and have a rotary drive body (52) that cooperates with a first engaging device (51) that is driven and arranged such that it circulates at a distance to the transport chain (50) in order to introduce a rotational movement thereof about a longitudinal axis of the transport means (33) via engagement in the rotary drive body (52). The heating device (H) has a first heating section with first heating units (30) for the uniform heating of the preforms (1) in their peripheral direction and a second heating section with second heating units (30) for the non-uniform heating of the preforms (1) in their peripheral direction (preferential heating). The first engaging device (51) is arranged in such a way that it is engaged with the rotary drive body (52) in the region of the first heating section and is not engaged with the rotary drive body (52) in the region of the second section. The heating device (H) has a second engaging device (45, 45, 45) that can be driven and is arranged such that it circulates at a distance to the transport chain (50), said second engaging device being arranged in such a way that it is engaged with the rotary drive body (52) in the region of the second heating section and also has the translation speed of the transport chain (50). Furthermore, the invention relates to a method for the thermal conditioning of preforms.

Provided is a polyester or co-polyester resin used in the manufacture of preforms suitable for making bottles and containers containing a carbon black, particularly lamp black carbon black, with a primary particle size in a range of from 100 to 160 nanometers.

A continuous cycle bottling line for containers of thermoplastic material comprises: a parison molding unit; a blow-molding unit for making containers; a unit for filling the containers; a thermal conditioning structure for the parisons, for heating and cooling the parisons in a heating module and in a cooling module, respectively; an automatic controlled-atmosphere storage system for containing the parisons and interconnected with the other parts of the line; a pressurization system configured to pressurize at least the following parts of the line: the storage system, the at least one blow-molding unit and the connections between the thermal conditioning structure and the storage system; where the heating and cooling modules, alternatively or in combination, i) are pressurized, ii) have a plurality of shutters configured to occlude the opening at the end of each parison, so that the interior of the parison remains closed when the parison is inside the heating and cooling module.
