A syringe for use in pressurized injection of a fluid is provided herein. The syringe includes a syringe barrel comprising a polymeric material having undergone expansion by stretch blow molding and by compression molding of an inner diameter of the barrel with a core member. In certain configurations of the syringe barrel, the stretch blow molding is provided through a nozzle of the syringe. Similarly, according to a further embodiment, a syringe for use in pressurized injection of a fluid is provided. The syringe includes a syringe barrel comprising a polymeric material having undergone expansion by stretch blow molding and by shrinking an inner diameter of the syringe barrel about a core member.

A device includes a first part having a co-molded first support, valve cover and elastic actuator, and a second part having an injection molded second support, valve seat, and variable-volume storage chamber pre-form. The pre-form is blow molded into a flexible pouch defining the variable-volume storage chamber. The one-way valve includes a semi-annular, curvilinear, relatively rigid valve seat defining axially-extending, opposing first marginal portions, and an axially-extending first mid-portion angularly extending between the opposing first marginal portions. A flexible valve member is superimposed on the valve seat and defines axially-extending, opposing second marginal portions fixedly secured on or adjacent to respective first marginal portions of the valve seat, and an axially-extending second mid-portion angularly extending between the opposing first marginal portions and superimposed onto the first mid-portion of the valve seat. The flexible valve cover and valve seat form a normally closed axially and angularly extending valve seam therebetween.

A plural preform assembly having nested preforms with an inner preform and an outer preform. The preforms are sealably joined together, defining a volume between the preforms. Propellant is disposed in the volume between the preforms. The preforms are later blow molded to provide a bag in bottle, bottle in bottle or similar container. The propellant charge is already present when blow molded, preventing the need for a later propellant filling step.

A blow-molding method for forming a squeezable or tubular plastic container is provided. The method includes molding a preform having a sidewall, an interior cavity, an open end, a closed end, and a neck adjacent the closed end of the preform. The neck of the preform has an engagement structure. The method includes providing a blow mold system including a blow mold cavity. The method includes placing at least a portion of the preform into the blow mold cavity, and blow molding a one-piece container body from the preform by inflating the preform within the blow mold cavity. The container body has an open end, a closed end and a neck adjacent to the closed end. Wherein the open end of the container body is formed from the open end of the preform, and the closed end of the container body is formed from the closed end of the preform. The method includes creating a dispensing opening through the closed end of the container body.

Methods and devices for manufacturing plastic preforms and plastic containers are provided. Methods of manufacturing a plastic preform having an inner undercut include forming a preform of plastic in amorphous state and inserting a plug within the mouth of the preform. The plug includes an upper plug member and an expandable element, the expandable element having an initial outer diameter in plan view with the plug in an initial condition and a deployed outer diameter in plan view with the plug in a deployed condition. Methods further include deploying the plug to the deployed condition with the expandable element positioned to engage a side wall proximate the inner undercut and crystallizing the plastic of the preform along the finish portion.

A liquid container and a liquid container with content liquid are easy to sort and dispose of, while preventing dripping of the liquid from a nozzle to the outside. A liquid container includes a container body configured to compartmentally form an accommodation space for content liquid, a tubular nozzle configured to be connected to an upper portion of the container body and guide the content liquid to the outside, and a liquid recovery channel configured to return the content liquid on the radial outside of the nozzle into the accommodation space. The container body, the nozzle, and the liquid recovery channel are formed by integral molding.

A plural preform assembly having nested preforms with an inner preform and an outer preform. The preforms are sealably joined together, defining a volume between the preforms. Propellant is disposed in the volume between the preforms. The preforms are later blow molded to provide a bag in bottle, bottle in bottle or similar container. The propellant charge is already present when blow molded, preventing the need for a later propellant filling step.

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).

A gripping device for supporting preforms made of a thermoplastic material, having necks with a different length, such necks having, in turn, a step obtained therein which may abut against a step obtained on the outer surface of the gripping device, i.e., the chuck, such a step of the chuck being located, for each preform, always at the same distance from the neck ring base.

Tapping assembly for a beverage, including container including a first and second container, wherein the first container has a neck portion and the second container is suspended in the first container, from the neck portion thereof. A neck region of the container is provided with at least one opening in a side wall thereof, preferably in a neck region of the first container, opening into a space between the first and second containers. The assembly further includes a connecting device, connected or connectable to the neck portion, wherein the connecting device includes at least one connecting element for connecting to the at least one opening, wherein the connecting element is connected to a source of pressurised gas.
