PREFORM NECK CRYSTALLIZATION METHOD
A wide-neck synthetic resin container has a neck, a body and a bottom. A top side of the neck is sealed by a cap. The neck includes a neck tubular section, an engagement section protruding outward therefrom and engaging the cap, and a flange protruding outward at the top side. The flange protrudes less than the engagement section. The neck's top side includes a first top side formed by the neck tubular section, and a second top side formed by the flange that is the same height level with the first top side and increases an area of the top side. The neck tubular section has a uniform thickness at an area immediately below the flange and an area where the engagement section is formed. A thickness of the flange is smaller than that of the neck tubular section, and the neck has been crystallized.
Method for hydroforming a container from a preform
A method of hydroforming a container from a preform. During the method, an injection nozzle is moved from a retracted position, where the nozzle is spaced away from the neck of the preform, to an intermediate position, where contact is established between a first contact surface of the nozzle and the finish of the preform. The nozzle is then moved from the intermediate position to an injection position, where a second contact surface of the nozzle abuts an abutment surface and the neck is axially compressed. With the nozzle in the injection position, a liquid is injected from the nozzle into the preform causing the preform to expand and form the container.

Apparatus and method to form hollow containers
Apparatus for forming hollow containers (110), suitable to contain in particular one or more liquid or semi-liquid food products, starting from parisons (F) made of thermoplastic material. The apparatus comprises a matrix (11) defined by a pair of molds (12) cooperating with each other to define a cavity (13) shaped like the container (110) to be formed, and to define a support channel (14), configured to define an additional portion (112) of said container (110). The apparatus also comprises a forming punch (17), operatively mobile through said support channel (14) to enter into/exit from said cavity (13) so as to thrust and blow one of said parisons (F) against the walls of said cavity (13) to form at least said container (110).

CONTAINER CLOSURE SYSTEM
The container system having a container and a screw-on cap that may that may be screwed onto the container and having an olive that is molded onto the screw-on cap and that is positioned against an annular edge area of the container opening is characterized in that the olive is molded onto the screw-on cap such that it fits against the exterior annular edge area of the container in a sealing manner, and in that the outer annular edge area has a continuously smooth surfaces.
MEDICAL FLUID CONTAINER
A medical fluid container includes a container interior and a connecting piece that forms an inner channel. The container interior can be accessed from the outside via the connecting piece. The connecting piece has an outer thread on a connecting piece longitudinal section. The inner channel expands in a substantially conical manner in a region of the outer thread, starting from the container interior, to then preferably transition into a first cylindrical channel shape which extends to a free opening of the connecting piece. A method can be used for producing the medical fluid container from a container blank.
