Method for the production of filled containers from thermally conditioned preforms
A method for producing containers filled with liquid content from preforms made of thermoplastic material. The liquid content is fed as a pressure medium into thermally conditioned preforms during a forming and filling phase in a mold of one of a plurality of forming stations arranged circumferentially spaced apart on a common, continuously rotationally driven working wheel. A compensating device compensates for thermal consequences of centrifugal force acting on the liquid content fed into the preform during the forming and filling phase. The compensating device imparts a temperature profile to the preform in a circumferential direction, which is not point-symmetrical in relation to a longitudinal axis of the preform to produce a thermally differentiated partial circumferential region. The preform is inserted into the mold such that the thermally differentiated partial circumferential region faces in a radial direction of the working wheel.
ENERGY EFFICIENT BLOW MOLDER CONTROL
Blow molder system and associated method optimizes the performance, energy efficiency and/or operating costs of the blow molder. A blow molder controller executes a system model that relates blow molder input parameter changes to the characteristics of containers generated by the blow molder. Equipped with energy and/or operating cost data for operating the blow molder, the blow molder controller can select a set of blow molder input parameter changes for the blow molder that: drives the containers produced by the blow molder toward desired container characteristics, in an efficient amount of time, and in cost effective manner, considering the energy costs involved in implementing the changes.
THREADED TAMPER EVIDENCE FINISH AND CLOSURE FOR CONTAINER
A tamper evidence closure is provided for rotatably engaging with a finish of a container to seal contents within the interior of the container. A multiplicity of thin connections attach a tamper evidence band to a circumference of the tamper evidence closure. A segmented cam extends around the circumference of the tamper evidence band. An angled lower surface of the cam facilitates passing the tamper evidence band over a tamper evidence ledge of the finish during assembly of the tamper evidence closure onto the container. An upper surface of the cam engages with the tamper evidence ledge to break the thin connections and retain the tamper evidence band positioned on the finish during loosening of the tamper evidence closure. Multiple overhang portions above the cam press against an upper portion of the tamper evidence ledge to ensure that the tamper evidence band remains engaged with the tamper evidence ledge.
METHOD OF INSTALLING A SEAL FOR A CONTAINER PRIOR TO CONTAINER EJECTION
A method of hydraulically blow molding a container from a preform using a liquid end product as a liquid blow medium. The method includes the steps of hydraulically blow molding a formed and filled container from a preform using the liquid blow medium and engaging a fluid tight seal with the container while the container is retained within a mold in the forming station. The engaging of the seal includes engaging an axially extending ring of the seal in one of a press-fit or frictional engagement with an inner surface of the container such that the seal is retained on the container by that engagement.
CONTAINER SYSTEM AND METHOD OF MANUFACTURE
A plastic, hot-fillable container is provided. The container comprises a blow molded body defining a longitudinal axis. The body including a base and a neck having at least one rib disposed about at least a portion of a circumference of the neck and transverse to the axis, and at least one angled thread. The at least one rib defining a cross section having a first portion and a second angled portion. Container systems and methods of manufacturing containers are disclosed.
PACKAGING
A container body comprises a base, a side wall extending from the base and a neck portion arranged to engage a closure for the container body, wherein: (i) said container body includes a cyclic olefin copolymer (COC) and polyester; or (ii) said container body includes a polymethylpentene (PMP) and polyester; wherein, in both cases (i) and (ii), the side wall of the container body has an L* of at least 90 and the neck portion has an L* of at least 84.
METHOD FOR MAKING A CONTAINER FOR A FLUID SUBSTANCE DISPENSING DEVICE AND DISPENSING DEVICE FOR THE SAID FLUID SUBSTANCE
A method for making a fluid substance container starting from a preform, the container coupled by a ring nut to a hermetic pump to form a fluid substance dispensing device, including heating and blow-moulding the preform to obtain the container; the preform formed of an external body and an internal body mutually assembled before being blow-moulded, the external body being cup-shaped with a first free end, the internal body being cup-shaped with a second free end having a flange whereby, when the internal body and external body are assembled, the flange abuts the first free end and protrudes a distance along an external perimeter of the external body near the free end, the external body being configured to form—once blow-moulded—the external recipient of the container while the internal body is configured to form a deformable bag housed inside the container, the ring nut having a undercut which engages the flange so that when the ring nut is removed the now empty deformable bag comes with it, in addition to the pump.
Storage bag
A method of making a storage bag comprising the following steps performed in any order: (a) forming a composite tube having an inner surface comprising a higher melting polymer, an outer surface comprising a lower melting polymer, two ends, and a diameter; (b) flattening the tube in a direction perpendicular to the diameter; (c) forming a joint at one of the ends at a temperature between respective melting points of the higher melting polymer and the lower melting polymer; (d) providing a composite sheet having a first side comprising a higher melting polymer and a second side comprising a lower melting polymer; and (e) disposing the composite sheet over the joint such that the first side comprising a lower melting polymer engages the joint and forming a lap seam over the joint at a temperature between respective melting points of the higher melting polymer and the lower melting polymer, and a storage bag made by such method.
Plastic container having a deep-set invertible base and related methods
In one embodiment, a method of processing a plastic container having a longitudinal axis is disclosed. The method includes: blow-molding a plastic container having an upper portion including a finish, a sidewall, a lower portion including a base defining a standing surface, and a substantially transversely oriented pressure panel having an inner annular wall and a central push-up portion located in the base, wherein a base mold portion is displaced longitudinally with respect to first and second side mold portions to form the pressure panel set above the standing surface; introducing heated liquid contents into the plastic container with the pressure panel located in an outwardly-inclined position entirely between the standing surface and the upper portion; capping the plastic container; and, moving the pressure panel to an inwardly-inclined position entirely between the standing surface and the upper portion.
BIODEGRADABLE AND COMPOSTABLE COMPOSITION
The present invention concerns a biodegradable and compostable composition comprising i) 15-70% by weight of at least one biodegradable and/or decayable aromatic polyester; ii) 0-40% by weight of dolomite and/or calcium carbonate particles having a polished surface; iii) 0-30% by weight of starch of vegetable origin; iv) 1-5% by weight of at least one oil of vegetable origin; v) 5-30% by weight of an additive chosen from hydrated magnesium silicate such as talcum powder; vi) 0-50% by weight of at least one aliphatic polyester.
