A mold includes a first mold for receiving a neck mold that holds a neck part of a resin preform having a bottom, and for enclosing the preform inside, and a second mold inserted into the neck mold. At least one of a first sliding surface between the neck mold and the first mold and a second sliding surface between the neck mold and the second mold includes a solid lubricant embedded therein.

The invention relates to a blow mould for transforming plastic parisons to form plastic containers, having a base part, a first side part and a second side part, wherein, in the assembled state of the blow mould, this base part together with the side parts form a hollow space, within which the plastic parisons can be expanded to form the plastic containers. According to the invention, at least one element of the blow mould has a first fastening section to which a first adapter element can be attached, which adapter element facilitates changing of the blow mould by means of a robot device, wherein this fastening section is formed in such a way that this adapter element can be attached releasably to this fastening section, and wherein this fastening section is formed in such a way that the blow mould can be arranged both with this adapter element and also without this adapter element on a transforming device for transforming plastic parisons to form plastic containers.

A method for forming plastic parisons to plastic bottles includes the following steps: introducing in a blow mold a plastic parison to be expanded, the blow mold having at least two lateral parts and a base part that is mobile in relation to said lateral parts in a longitudinal direction of the plastic parison; inserting a rod-shaped element in the interior of the plastic parison through a mouth of the plastic parison; applying a first pressure the plastic parison, applying a second pressure to the plastic parison, the second pressure deviating from the first pressure and being higher than the first pressure, applying a third pressure to the plastic parison, the third pressure deviating from the second pressure and being higher than the second pressure. The base part is advanced in the longitudinal direction of the plastic parison while at least temporarily applying the second pressure to the plastic parison.

A blow mold provided with a locking system for mutually locking each half-mold with the related half-mold holder, thus allowing a simpler and quicker replacement of the side half-impressions of the mold. The blow mold of the invention provides for the side half-impression of each half-mold to be fixed in a cavity of the corresponding mold holder by actuating at least one quick coupling device comprising a bar (23) inserted in one of the two longitudinal edges of the half-mold holder (3) and adapted to move only by rotation about an axis thereof; actuation means (22) adapted to actuate a rotation of said bar; and at least one locking fin (21) fixed along said bar (23) and adapted to move, by rotating the bar (23), from an unlocking position to a locking position in which said locking fin interacts with the respective half-mold (2).

To simply sterilize a blow-molding machine.

A mist or gas of hydrogen peroxide or a mixture thereof is introduced through a valve block (14) disposed adjacent to a molding die (13), thereby sterilizing at least the molding die (13) and an extension rod (15) that extends into the molding die (13) through the valve block (14).

A plastic container comprises an upper portion including a finish defining an opening into the container, a lower portion including a base defining a standing surface, a sidewall extending between the upper portion and the lower portion, the sidewall defining a longitudinal axis, and at least one substantially transversely-oriented pressure panel located in the lower portion. The pressure panel is movable between an outwardly-inclined position and an inwardly-inclined position to compensate for a change of pressure inside the container. The standing surface defines a standing plane, and the entire pressure panel is located between the standing plane and the upper portion of the container when the pressure panel is in the outwardly-inclined position.

Apparatus (1) for reshaping plastic preforms (10) into plastic containers (20) has a blow moulding device (14) which has at least two side parts (14a, 14b) and a base mould (14c) which form a hollow space inside which the plastic preforms (10) are reshaped into the plastic containers (20), wherein the apparatus has a changing device (40) which is suitable and intended either to remove the complete blow moulding device (14) or only parts (14a, 14b, 14c) of the blow moulding device (14) from the blow mould supports (16) thereof and/or to arrange them on the blow mould supports (16), wherein the base mould (14c) is arranged on a base mounting (19), and in a changing mode, through a lifting movement (H) and in particular a lifting and/or lowering of the base mounting (19), the base mould (14c) can be connected to the base mounting (19) or can be disconnected from the base mounting (19), and between the base mounting (19) and the base mould (14c) at least one first disconnectable media connection (21) is provided, by means of which a flowable medium can be supplied to the base mould (14c) and/or by means of which the flowable medium can be discharged from the base mould (14c). According to the invention the media connection (21) between the base mounting (19) and the base mould (14c) can also be made and/or can be broken by the lifting and/or lowering of the base mounting (19).

An arrangement is described. The arrangement comprises a closing unit for a blow-molding machine having a first and second mold carrier and a blow-molding tool arranged on the closing unit having two tool halves. A mold lower part of each tool half is movable in relation to the mold upper part of each tool half in a second movement direction different from the first movement direction back and forth between an open state and a closed state by means of at least one first or at least one second actuator and the blow-molding tool in the closed state of the two tool halves delimits a mold cavity having undercuts when the two mold lower parts are also in the closed state. The actuators, for example hydraulic cylinders, may arranged on the closing unit and make them able to be coupled to the mold lower part.

A hollow article is molded in a state where an inner surface of a neck portion including an inner screw portion is held by an inner neck mold, and then, the hollow article is demolded from the inner neck mold by inserting an ejection rod into the hollow article to be engaged with an inner surface of the hollow article and rotating the hollow article together with the ejection rod.

First, a composite preform 70 including a preform 10a and a plastic member 40a in close contact with the outer surface of the preform 10a is made by preparing the preform 10a made of plastic material and arranging the plastic member 40a to surround the outer surface of the preform 10a. Subsequently, the composite preform 70 is heated and inserted in a blow molding die 50 and undergoes blow molding in the blow molding die 50, by which the preform 10a and the plastic member 40a of the composite preform 70 are inflated integrally and a composite container 10A is obtained.
