摘要:
In a method for forming a package, a package with the shape of a container is formed of a cardboard blank, the package having a bottom and side walls extending upwards from the bottom. At the end stage of compression molding, a rim of molding material extending sideways is molded to the upper part of the side walls when the mold is kept closed in such a way that a mold cavity corresponding to the rim is formed by moving a counter surface inside the mold backwards from a surface opposite to it, after which the molding material is introduced into the mold cavity.

A method and a tool (562) for forming a tray (100) or container (478) which may be hermetically sealed having a flange encapsulated by or formed from injection-mold material. The tray (100) has a flange (116) extending outwardly from a sidewall (114) of the tray, and containing irregularities induced by the creation of the tray (100). An encapsulating material surrounds the flange (116) in substantially uniformly thick manner, and along with the flange (116) defines an encapsulated rim (124). The encapsulating material is generally a plastic such as polyolefin, nylon, or polyethylene, but may also be made from other materials. This encapsulating material covers a portion of the flange (116) and extends a set distance from the flange's (116) outer edge.

Sterilizable plastic bottle for sterile infusion solutions, of the type sealed by a pierceable rubber plug (4) and a safety metal blocking ring. The bottle (1) is made of plastic material and is provided, at the bottleneck area cooperating with said rubber plug, with a ring (2) of rigid material, substantially free from thermal size modifications, at least within the bottle (1) storage and sterilisation temperature range - varying between -20°C and 120°C - and strictly fitting the external surface of the neck of the bottle (1).

It is disclosed a vacuum or modified atmosphere package for food products which are susceptible to release liquids and/or gases, said package comprising 1) a tray (1) made of plastic material, having a bottom (3), and having sidewalls (5) terminating with a jutting edge, the tray comprising at least two layers, of which a layer facing inward of the tray consists of a sheet (7) of a substantially open-cells expanded thermoplastic material having holes (10) or slots on at least part of its upper surface, and a lower layer facing outward of said tray consists of a gas-barrier composite film (9); the tray further having a peripheral frame (11) made of plastic material and having barrier properties with respect to the diffusion of gases, the peripheral frame (11) being coupled to the tray edge (6) all around the perimeter thereof and having substantially listel-like sides with an angular cross-section comprising two flanges (12,13) of which a first flange juts out as a prolongation of the tray edge and a second flange engages the tray edge from beneath; 2) a food product (4) susceptible of releasing liquids and/or gases placed onto the bottom of said tray; and 3) a cover (2) for said tray consisting of a gas-barrier composite film which adheres onto the first flange of the peripheral frame and, optionally, onto the tray edge so as to maintain a vacuum or a modified atmosphere within the package.
摘要:
Bei einem Verfahren zur Herstellung von Flaschenkästen aus Kunststoff werden zur Herstellung von Griffholmen (1) von den Kastenseiten her in Längsrichtung der herzustellenden Griffholme Formschwerter (8, 9) in den Formhohlraum (12) geschoben, die nach Einspritzen des Kunststoffmaterials und vor Entformung des Flaschenkastens abgezogen werden. Der Flaschenkasten nach der Erfindung zeichnet sich durch Griffholme aus, die in Längsrichtung des Griffholms ein geschlossenes Hohlprofil aufweisen und/oder durch Profile gebildet sind, die durch Anschweißen eines weiteren Pro-. fils zu einem geschlossenen Hohlprofil ergänzt werden. Durch das geschlossene Hohlprofil wird eine Versteifung des Griffholms erreicht und ferner das Trageverhalten verbessert.
