According to the present invention, in order to improve the productivity of an injection stretch blow molding machine, when a core mold is lifted during mold opening at an injection molding part of the injection stretch blow molding machine, stress is dispersed so as not to concentrate at an area where the thickness changes between a preform opening and a preform body so that the preform body is inhibited from being lifted at a skin layer formed in the area where the thickness changes between the preform opening and the preform body. In a preform (30) where a skin layer (34) at the surface has a lower temperature than a middle layer (35) so as to allow a preform body (32) and a preform bottom (33) to expand and deform from the inside of the preform toward the outside of the preform, the skin layer (34) bridging between the inner surface of the preform body (32) and the inner surface of the preform opening (31) is formed in a tapered shape that opens upward at an outward slant with respect to an extension line (38) of the inner surface of the preform body (32) extending above the skin layer (34) so that, during the lifting of the core mold, the stress exerted from the preform body (32) is dispersed at a stress dispersing plane section (39) formed with the skin layer (34).

A facility for the production of containers from blanks, which facility includes: a forming unit equipped with a rotating carrousel driven by a motor; a unit for heating blanks, equipped with infrared emitters and a power feed for each emitter; a control unit having in the memory a nominal speed setpoint .sub.N of the rotation of the carrousel and a nominal electrical power setpoint P.sub.N. The control unit is programmed for: controlling the rotation of the carrousel according to the nominal speed setpoint .sub.N. During its acceleration: taking into account the real instantaneous speed of rotation of the carrousel, and regulating the electrical power of the feed to an instantaneous value P such that: $P\left(t\right)=P_N.Math.\frac{}{{}_N}$

A composite strip which extends in a main direction between first and second ends and which comprises a main strip comprising first fibres embedded in a matrix. The first fibres are made of carbon, an electrically conducting material, and the matrix is made up of at least one polymer. The composite strip further comprises a junction layer formed of an electrically conducting junction material. The junction layer is placed on the main strip.

In a carbonated drink filling method, a preform is continuously transferred and introduced into a heating furnace, heated to a temperature for molding the preform into a container, molded into the container in a molding die after the preform exits the heating furnace, conveyed in an upright position during which a coolant (F) is injected to a bottom of the container to cool the bottom. The container is filled with a carbonated drink (a) through a mouth portion of the container, and the mouth portion is then sealed. The coolant is injected in the cooling to the bottom of the container from a nozzle opening on either or both sides of a conveyance line of the container, and the nozzle opening is directed diagonally upward to the bottom of the container in such a manner that an extension of the nozzle opening intersects with the conveyance line of the container.

A formulation for producing a polymeric material including polypropylene, a chemical blowing agent, and optional components as described.

A method is provided, wherein a lighting device (200, 300, 400, 500) comprising an at least partly light transmitting envelope (110) and a solid state light source (120) is manufactured. The method comprises arranging (710) an at least partly light transmitting plastic material (140) in a mold (130) having a surface structure (132) arranged on an inner surface portion of the mold and blow molding (720) the plastic material so as to form the envelope. During the blow molding, the surface structure is at least partly transferred to the at least partly light transmitting plastic material, thereby forming an optical structure (150) on a portion of an outer surface of the envelope. The envelope is then removed (730) from the mold and arranged (740) to at least partly enclose the solid state light source. The optical structure may be formed to generate a desired optical effect.

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.

The present invention concerns a handling plate for handling or aftertreatment of a plurality of mouldings, wherein the handling plate has a plurality of handling and/or aftertreatment tools arranged in columns and rows. In order to provide a treatment plate which can be used in relation to different tools it is proposed according to the invention that the spacings between the handling and/or aftertreatment tools are variable within the columns and/or within the rows.

An inflatable balloon cuff may be adapted to seal a patient's trachea when associated with an endotracheal tube. Configurations of these cuffs that include tapered regions with certain characteristics, such as cuff wall diameter and thickness, may provide improved sealing of the trachea.

A method and a device for producing blow-molded containers, which are sterile at least in some areas, in a blow-molding machine. A preform made of a thermoplastic material is first heated, then stretched by a stretching rod in a blowing station, and then supplied with a pressurized fluid via a blow nozzle, wherein a sterilization device is arranged in the blowing station. The sterilization device has at least one radiation source which emits a sterilizing radiation onto the stretching rod and/or onto the blow nozzle.
