Method for gas filling of a compartment of a flexible container
A method for handling containers (I) of collapsible type in a filling machine (20) comprising consecutively arranged stations (S1, S2, S3, S4, S5, S6) comprising a filling station (S3) and a gas filling station (S5), the method comprising intermittently moving the containers (I) to the consecutively arranged stations (S1, S2, S3, S4, S5, S6), supplying, at the filling station (S3), liquid product into the product compartment (5) and supplying, at the gas filling station (S5), gas into the handle compartment (7). The filling station (S3) and the gas filling station (S5) are operated such that liquid product is supplied to the product compartment (5) of one of the containers (I) while gas is supplied to the handle compartment (7) of another of the containers (I). The step of supplying gas at the gas filling station (S5) comprises providing a first gas flow (Qi) at a first pressure (Pi) and delivering said first gas flow (Qi) from the nozzle (30) to the handle compartment (7) via said inlet (11), and subsequently providing a second gas flow (Q.sub.2) at a second pressure (P.sub.2), lower than said first pressure (P.sub.1), and delivering said second gas flow (Q.sub.2) from the nozzle (30) to the handle compartment (7) via said inlet (11) for establishing a target pressure (P.sub.T) inside said handle compartment (7) corresponding to said second pressure (P.sub.2).
Multi-Layer Injection Molded Container
A coinjection molded multi-layer container includes an inner layer, an outer layer, and a barrier layer. The inner layer includes a first polymeric material and forms an inside surface of the container. The outer layer includes the first polymeric material and forms an outside surface of the container. The barrier layer is located between the inner layer and the outer layer and includes a second polymeric material less permeable to gas than the first polymeric material. The barrier layer is biased toward the inside surface or the outside surface such that the inner layer and the outer layer have different thicknesses.
APPARATUS AND METHOD FOR VACUUM SKIN PACKAGING OF A PRODUCT
A method and apparatus can be used for vacuum skin packaging of a product. The product can be arranged on a support comprising providing a film sheet above said support with said product being arranged between the support and the film sheet. The film sheet can be air tightly fixed to the support. The wall of the support can be perforated to form at least one through hole. At least a portion of air from within the support underneath said film sheet can be removed through the at least one hole. A packaged product is obtainable using the method and apparatus.
Flexible pipe and coupling therefor
Construction of a sealed connection between an elastomeric or synthetic polymer flexible pipe or hose and a metallic coupling member. The coupling member surrounds an armor layer at a free end of the flexible pipe or hose. A sealing area is defined by a recessed portion of the pipe coupling into which a sealing material is introduced. An inner liner layer of the flexible pipe or hose may extend into the sealing area where it is bonded to the sealing material. The sealing material and the inner liner layer may each be comprised of a semi-crystalline thermoplastic material. Furthermore, a reinforcement material may be provided in the inner liner layer.
Multi-layer injection molded container
A coinjection molded multi-layer container includes an inner layer, an outer layer, and a barrier layer. The inner layer includes a first polymeric material and forms an inside surface of the container. The outer layer includes the first polymeric material and forms an outside surface of the container. The barrier layer is located between the inner layer and the outer layer and includes a second polymeric material less permeable to gas than the first polymeric material. The barrier layer is biased toward the inside surface or the outside surface such that the inner layer and the outer layer have different thicknesses.
Heat-sealing apparatus and method for forming composite heat seal structure
A heat-sealing apparatus for forming a composite heat seal structure, includes a belt conveying, heating and press bonding portion configured to convey and heat a heat seal material to form a band-shaped peelable seal, and a die roll press bonding portion configured to add a linear peelable seal to the band-shaped peelable seal in a longitudinal direction of the band-shaped peelable seal for forming the composite heat seal structure.
SYSTEMS AND METHODS FOR THE APPLICATION AND SEALING OF END CLOSURES ON CONTAINERS
The invention is directed to a system and method for hermetically sealing a closure to a container comprising a die assembly and a mandrel assembly. The mandrel assembly comprises an outer mandrel, an inner mandrel, and an ejector disposed within an inner circumference of the inner mandrel. At least the outer mandrel is configured to translate a first distance in a first time period, the inner mandrel and the ejector are configured to translate a second distance in a second time period, the inner mandrel is configured to retract a third distance in a third time period, and the ejector is configured to retract the third distance in a fourth time period.
A METHOD FOR FORMING A TUBE AND A METHOD AND AP ACKAGING MACHINE FOR FORMING A PACKAGE
There is described a method for forming a tube (3) of a web (4, 4) of packaging material comprising the steps of advancing the web (4) of packaging material along a web advancement path (P), overlapping a first lateral edge (19) of the web (4, 4′) of packaging material with a second lateral edge (20) of the web (4, 4) of packaging material for obtaining a longitudinal seam portion of the tube (3) and fusing at least an internal outer surface (34) of the first lateral edge (19) and an external outer surface (37) of the second lateral edge (20) with one another for longitudinally sealing the seam portion of the tube (3). The step of fusing comprises at least the substeps of directly heating the external outer surface (37) of the second lateral edge (20) and heating by contact the internal outer surface (34) by establishing contact between the internal outer surface (34) and the directly heated external outer surface (37).
Sonotrode and anvil for ultrasonic welding of plastics, method for producing a plastic container
A combination of a sonotrode and anvil, includes a sonotrode/anvil surface and a first row of sonotrode/anvil welding contact elements. The first/second series of each of the sonotrode/anvil welding contact element of a first row includes a first/second adapted lateral surface that joins at least one part of the first/second plateau surface with at least one part of the sonotrode/anvil surface side. The first/second adapted lateral surface includes a first/second curved surface positioned between the first/second plateau surface and the first/second substantially straight surface. The first/second curved surface has a convex outward arch. The welding contact element is positioned in relation to the anvil welding contact element such that the sonotrode welding contact element is positioned during welding next to the anvil welding contact element and is provided to form at least one part of a weld seam.
