A blow molding, filling and closing process for producing a filled and closed container product that can be stored as well, in particular in the form of an ampoule product which is formed from a plastic material and has a single-layer container wall or ampoule wall and which, during initial use, permits the withdrawal, in particular for an oral use of the product content, by opening at least one withdrawal opening for withdrawal purposes, is characterized in that plastic materials suitable for the process are selected which are tasteless and/or odorless or essentially tasteless and/or odorless in interaction with the contents of the container before and during use and which retain this tastelessness and/or odorlessness even after prolonged storage.

Method for processing hot-filled plastic containers are provided. In some embodiments, the method may include hot-filling a plastic container, sealing the container, and conveying the sealed container, each with an inner annular wall and a push-up portion in a first position. In some embodiments, the method may further include creating a vacuum pressure in the hot-filled and sealed container and repositioning or inverting the push-up portion from the first position to a second position under the vacuum pressure.

A method for producing a foamed particle molded article provided with a skin, includes: forming a hollow molded article; filling a hollow part of the hollow molded article with polypropylene-based resin foamed particles; and heating and fusing the particles to each other. A melt elongation at 190 C. of the polypropylene-based resin forming the hollow molded article is 100 m/min or more. A half-crystallization time at 100 C. of the polypropylene-based resin is between 25 to 80 seconds. In heat flux differential scanning calorimetry, a melting peak temperature of the polypropylene-based resin is between 130 to 155 C., a partial heat of fusion at 140 C. or more of the polypropylene-based resin is between 20 to 50 J/g, and a ratio of the partial heat of fusion of the polypropylene-based resin to the total (partial heat of fusion/total heat of fusion) is between 0.2 to 0.8.

A method includes injection molding a preform using a two phase injection system having a first phase in which a material is injected into the preform and a second phase in which the material is injected into the preform. The preform is disposed in a mold. The preform is blow molded into an intermediate article. The intermediate article is trimmed to form a finished container. The first phase includes injecting a material into the preform to form a single layer of the preform and the second phase includes injecting the material to form inner and outer layers and an intermediate layer between the inner and outer layers. The inner and outer layers include the material and the intermediate layer includes at least one additive. Finished containers are disclosed.

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.

The present invention relates to a base assembly (100) for forming a base portion of a plastic container. The base assembly comprises a base pedestal (104), a base mold attached to the base pedestal, a push rod (102) movable between a first position and a second position with respect to the base mold to reposition a portion of the plastic container, and an activation mechanism adapted to move the push rod between the first position and the second position.

The present disclosure relates to methods of maintaining sterility of an aseptic work zone of a blow-fill seal operation so that low acid foods may be aseptically processed and packaged. The methods of the present disclosure further provide for maintain the sterility of the aseptic work zone such that the aseptic work zone does not have to be enclosed in a separate sterile environment during the blow fill seal process. The methods of the present disclosure further provide a sterilization procedure that is compliant with FDA regulations related to the aseptic packaging of low acid food products. Further disclosed, are methods for producing a hermetically sealed container containing a low acid food product.

A fill assembly sterilization method and system for a blow/fill/seal machine utilizes a closed loop circulation of sterilant containing gas. A typical sterilant is nitrogen dioxide in humidified air. The closed loop includes a shroud that defines a plenum and encloses the fill system. Optionally, at least one high efficiency particulate absorption (HEPA) filter is provided in the closed loop. Sterility assurance level of 10.sup.6 can be achieved by subjecting the fill system to the sterilizing gas for at least 20 minutes at a temperature in the range of about 18 C. to about 30 C. Preferred sterilant gas is humidified air containing about 10 to about 20 milligrams of nitrogen dioxide per liter.

Mold filling machine for producing and filling containers made from preforms, comprising a mold filling station with a mold for receiving a preform, wherein the mold has an opening, such that an opening region of the preform in the mold is accessible, the mold filling station having a treatment unit with at least two treatment subunits, which are arranged movably in the treatment unit in such a way that the treatment subunits can be positioned alternately over the opening and the treatment unit has a sealing element, which can be positioned over the opening of the mold in such a way as to form a gastight space, which includes the interior space of the preform and/or container and the treatment subunits.

Apparatus (1) for manufacturing sterile containers (2), comprising: a shaping unit (3) for shaping the containers (2); a chemical sterilising unit (4) for sterilising the shaped containers (2) by means of a sterilising agent; a first box-like case (5) configured to delimit a first volume (6) inside which the containers (2) move forward during their transferral from the shaping unit (3) to the sterilising unit (4), a first air pressurising device (7) for pressurising the air, which is located externally of the first volume (6) and configured to introduce therein air having pressure comprised between 1 Pa and 10 Pa, the pressurising device (7) comprising at least one first fan (8) and at least one first heating element (9) configured to maintain the temperature of the pressurised air over the dew point of the sterilising agent.
