Abstract:
A thermoplastic bottle (100) has a crimped valve cup (204) and a method of manufacturing a thermoplastic bottle (100) includes crimping a valve cup (204) to such a bottle. The thermoplastic bottle (100) and valve cup (204) may be used in a system to dispense aerosol products. At least one protrusion extends from a flange of the bottle (100) to which the valve cup (204) is crimped. Prior to being crimped to the bottle (100), the valve cup (204) is set to the bottle (100) with an interference fit between a crimping portion of the valve cup (204) and the protrusion (114). The interference fit prevents shifting of the valve cup (204) from its set position on the bottle (100) prior before the valve cup (204) is crimped.
Abstract:
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.
Abstract:
The rigid plastic container (V) is designed for being assembled with another rigid plastic container (V) and forming a dual-container dispenser. The container (V) comprises a neck finish (2) and a stretched body (3') closed at its bottom end. The neck finish (2) comprises a tubular part (20), an upper wall (21), a lower wall (22) and a side wall (23). The side wall (23) extends between the upper (21) and lower (22) walls and said side wall (23), upper wall (21) and lower wall (22) form a housing (H) for the tubular part (20). The housing (H) comprises an assembly surface (S) formed by the edges of the side wall (23), upper wall (21 and lower wall (22). The tubular part (20) is opened at both ends and forms a path through the upper wall (21), within the housing (H) and through the lower wall (22), for filling the stretched body (31).
Abstract:
A plastic material container, e.g. a beverage bottle, having a neck (2) which requires the use of a smaller amount of plastic than the bottle necks of the prior art, and which is able to ensure a complete functionality for coupling the cap, ensuring at the same time the possibility of implementing the traditional supporting,; sealing and handling operations of the bottle carried out during the various steps of manufacturing the same.
Abstract:
A wide-mouth container (1) has a body and a rim (3) defining an opening for the container, and is made of a material such as PET or PEN. The first step in its manufacture comprises injection moulding a preform (15) which has a rim (3) formed at its mouth and a continuous body-forming portion (120) extending across the preform from the inner periphery (21 ) of the rim. An injection-moulded handle (90) is then attached to the preform, with the handle having two opposed ends received respectively at different locations around the rim and being pivotable on the rim. The preform can then be stored or transported in this condition. In the final step, the preform after heating is placed in a moulding cavity (61 ) of a blow moulding apparatus (60) with the preform being located by means of the rim (3). The mould includes a recess (115) around the rim to accommodate the handle (90) attached to the rim (3) during the operation of the blow moulding apparatus. The body-forming portion (120) expands in the cavity to form the side walls (20) and bottom wall (2) of the container. The side wall (20) of the container contacts a skirt (26) forming the outer part of the rim (3), thus forming a box section which serves to retain the handle. The skirt (26) and the interior surface of the ends of the handle (90) adjacent thereto have cooperating detent arrangements which tend to latch the handle on the container in one or more predetermined pivotal positions to assist pouring. The ends of the handle can be received in the rim other than at diametrically-opposed locations, for example at locations which are spaced around the rim by 90 to 175 degrees.
Abstract:
The invention relates to a method and a device for producing cartridges. An injection-molded preform produced from a thermoplastic material is biaxial orientation-molded in a blow mold to give a container. Molding is carried out by stretching and by adding a pressurized blowing gas. The container is removed from the blow mold as an intermediate product and a bottom zone of the container is cut off. The cartridge can be closed with a bottom part optionally prior to or after filling.
Abstract:
Es ist ein Verfahren zur Herstellung einer Kunststoffflasche, insbesondere einer PET-Flasche, vorgeschlagen, bei dem ein Preform (1), der einen im wesentlichen zylindrischen, einseitig geschlossenen Körper (2) aufweist, an den ein Halsabschnitt (4) mit einer Ausgiessöffnung (5) anschliesst, und der in einem Kunststoffspritzverfahren hergestellt wird, in eine Formkavität (11) einer Blasform (10) eingebracht und mit Hilfe einer Blasdüse (13) durch Überdruck gemäss der Formkavität (11) aufgeblasen wird. Zum Unterschied von den aus dem Stand der Technik bekannten Verfahren erfolgt die Abdichtung zwischen der Blasdüse (13) und dem Preform (1) im Inneren des Preforms (1). Es sind auch ein für das Verfahren ausgebildeter Preform (1) und eine zugehörige Blasform (10) beschrieben.
Abstract:
Procédé de fabrication d'un corps creux par extrusion d'une résine thermoplastique à l'aide d'un accumulateur (6) comportant un espace d'accumulation (17) délimité entre le noyau central et l'enveloppe extérieure (7), caractérisé par le fait qu'il comporte les étapes consistant à appliquer ledit accumulateur jointivement contre un élément de moule (3) muni d'un logement creux (16) en engageant une pièce d'extrémité (15) dudit noyau central dans ledit logement creux de manière à former une cavité de moule (19a), mouler, dans ladite cavité de moule, une portion d'extrémité du corps creux à fabriquer, écarter ladite portion d'extrémité moulée de ladite ouverture d'extrémité à l'aide d'un organe mobile, expulser simultanément de la résine dudit espace d'accumulation à travers ladite ouverture d'extrémité autour dudit noyau central de manière à extruder une couche de résine raccordée à la périphérie de ladite portion d'extrémité moulée.
