Abstract:
A thermoplastic bottle has a crimped valve cup and a method of manufacturing a thermoplastic bottle includes crimping a valve cup to such a bottle. The thermoplastic bottle and valve cup may be used in a system to dispense aerosol products. At least one protrusion extends from a flange of the bottle to which the valve cup is crimped. Prior to being crimped to the bottle, the valve cup is set to the bottle with an interference fit between a crimping portion of the valve cup and the protrusion. The interference fit prevents shifting of the valve cup from its set position on the bottle prior before the valve cup is crimped.

Abstract:
Tapping assembly (1) for a beverage, comprising a first (20) and second (21) container, wherein the first container has a neck portion and the second container is suspended in the first container, from the neck portion thereof, wherein a neck region of the container is provided with at least one opening (22) in a side wall thereof, preferably in a neck region of the first container, opening into a space between the first and second containers, wherein the assembly further comprises a connecting device (5), connected or connectable to the neck portion, wherein the connecting device comprises 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.
Abstract:
A container (1) having a body and a rim (3) defining an opening for the container, the container being made of a material such as PET or PEN, is manufactured in a two-stage process. The first stage comprises injection moulding a preform (15) which has a rim (3) formed at its mouth and a continuous body-forming portion (32) extending across the preform from the inner periphery (19) of the rim, the rim having an outwardly-directed extent and including a downwardly-extending portion (21) spaced outwardly from the inner periphery and an outwardly-extending portion (5,6,29) located outwardly of the downwardly extending portion. In the second stage the preform is placed in a moulding cavity (56) of a blow moulding apparatus (7) at an elevated temperature with the preform being located by means of the rim (3). The body-forming portion expands in the cavity to form the container side wall (20) and bottom wall (2). The upper region (18) of the side wall contacts the downwardly-extending portion (21) of the rim such as to form a box section (25). The side wall (20) has at its upper side region a step (23) above which the diameter of the cavity is substantially equal to or approaches the diameter of the downwardly-extending portion (21) of the rim. Below the step (23) the diameter is less than the diameter of the inner periphery of the rim and tapers therefrom inward downwardly to the bottom wall (2) at an acute angle, whereby the containers can internest.
Abstract:
A pressure wide-mouth container made of synthetic resin and having a cylindrical body portion, a flange portion projecting from the periphery of a wide mouth formed at one end of the body portion; and a bottom portion closing the other end of the body portion. The flange portion and a peripheral portion of the wide mouth are formed by injection molding and not drawn after the injection molding is carried out. The body portion except the peripheral portion of the wide mouth and the bottom portion are formed by the injection molding and drawn by a blow molding to be performed after the injection molding is carried out and the bottom portion is drawn at a lower drawing ratio than the body portion.
Abstract:
There is described a container for storing and/or dispensing a substance, the container (10) defining a dispensing orifice (13) and a filling orifice (14) spaced from said dispensing orifice (13), the filling orifice (14) being recessed into the container (10) and permanently sealed following the introduction into the container (10) of the substance to be stored and/or dispensed. There is also described a closure for a container (10), the closure defining a dispensing orifice (13) and comprising a closure means (11) flexibly hinged to the closure for movement between an open position and a closed position in which the closure means (11) closes the dispensing orifice (13), and a projecting portion provided on one of the closure or closure means and adapted so as to be progressively received within an opening (30) provided in the other of the closure and closure means (11) as the closure means (11) is moved towards said closed position, the projecting portion so engaging the means defining the opening as to prevent the closure means from moving from said open position to said closed position as the container is filled. There is also described a closure for a container, the closure defining a dispensing orifice (13) and comprising a closure means (11) for closing the dispensing orifice (13) and a tear tab (23) formed integrally with the closure and connected thereto by a frangible tear point (29), the tear tab (23) being so arranged as to partially overlie a surface of the closure means (11) when said closure means (11) is in said closed position thereby enabling the tear tab (23) to be joined to the closure means (11) to secure the closure means (11) in said closed position, the tear tab (23) being further joined to the closure by a frangible manufacturing support (35) adjacent the portion which in use is joined to the closure means (11).
Abstract:
Method and apparatus for converting, by reshaping, thin-walled nestable plastic containers into non-nestable container products wherein the nestable container is telescopically mounted on and releasably locked to a complementary male mold member, the nestable container thereafter being heated to a predetermined temperature to permit ready deformation thereof, and subsequently expanded against the non-nestable inner wall configuration of a mold cavity by differential fluid pressure to form non-nestable container products. In order to mold uniform container products by a continuous molding operation, the nestable plastic container is held in fixed relation relative to the male mold member in the vicinity of its open mouth where the container is insulated from heat.
Abstract:
An aerosol dispenser, an outer container for an aerosol dispenser and a preform for an outer container. The aerosol dispenser, outer container and preform each have a neck, which in turn has a crimp ring, to receive a valve cup clinched thereto and a lower neck potion upon which the crimp ring is mounted. The lower neck portion extends between the bottom of the crimp ring and a shoulder which transitions into the sidewalls. The crimp ring preferably has a greater axial length than the lower neck portion. This geometry allows flexibility in the thickness throughout the thickness of the entire neck. The geometry advantageously minimizes distortion of the neck in the event of overpressurization.
Abstract:
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.
Abstract:
A method for fabricating a preform by providing a plurality of preform segments which each define a portion of a preform, positioning said preform segments in continuous contact with each other along at least one edge of said preform segments such that said plurality of preform segments define a cavity, and bonding each of said preform segments to at least one other preform segment such that said plurality of preform segments forms a continuous whole.
