摘要:
A two way valve assembly for use in flexible containers having a pair of one-way fluid passages. Thus, the one-way passage provides for fluid flow from the container interior to the external atmosphere while the other one-way passage provides a path for fluid flow from the external atmosphere to the interior of the container. Apparatus is provided for selectively closing one or both one-way fluid flow passages.

A cardboard container particularly for solid, granular, powder or even fluids products is described, having a substantially box-shaped body open at the top and an upper closing wall (8) which disposes inside the body of the container at a certain distance from the upper edge (3) thereof and a pre-cut line (22-23), designed to facilitate the detachment of a disk (8′) to form an opening for access to the container is provided; the body and the upper closing wall and possibly a movable flap, which acts as a lid once the disk has been removed, are formed from a single blank (100).
摘要:
A container (1) made of flexible material (2) is, suitable for either vacuum-packed or nonvacuum-packed products and/or sterilizable products, or for containing liquid products, having stiffening plates as a cover (3) and as a base plate (4) and a system of folds which involves a horizontal folding edge (22) and two opposed vertical folding edges (23). In a first embodiment, the cover plate (3) has a lid (6), for example opening on a hinge, and the base plate (4) contains an expansion chamber (21), which communicates with the outside in order to compensate for any possible variation in the volume of the product inside the container (1), at the moment of packing. In another embodiment of the container (1), the cover plate (3) is provided with a dispenser spout (25), and the base plate is joined to the cover (3), in such a way as to allow the containers (1) to be stacked on top of each other, being used inside the plates (3, 4), which hold the plates (3,4) together after the axial crushing of the empty container.
摘要:
A packaging bag, in particular for cooked ham, made of thermoweldable material and provided, on at least one of its walls, with a drainage hole. The inside of the bag also includes a drainage valve secured at the wall of the bag. The drainage valve comprises a disc of a plastic material, and is provided with a plurality of radial, spaced ribs projecting from its surface. The ribs face the internal surface of the wall of the bag, and the wall is secured to the ribs by thermowelding. The center zone of the disc will match with the center zone of the drainage hole.
摘要:
A cardboard container (1) is described particularly for solid, granular or powder products, but also adaptable to contain fluid products, in particular paste or cream products and the like. The container is obtained from two cardboard blanks (10), (11), the first giving rise to the body of the container, the second to a top closure wall. The body of the container rises conically from a rectangular base (2) to give rise at the top to a substantially octagonal mouth, wherein is inserted said reclosure cover (8) having peripheral flaps (h) upwardly folded and positioned inside the mouth of the container, to be blocked by corresponding flaps (f, f′) of the upper edge (3) of the container (1), which are folded inwardly and fixed by means of glue or heat-sealing adhesive. In one embodiment, the container (1) can be made hermetic, for containing fluid products, by applying a film (40) to the blank wherefrom the body of the container is produced, and a thin layer of aluminium (50) to the blank (11) giving rise to said top closure wall (8), wherein a cut line (22, 23) is provided to facilitate removal of a disk (8′) and form an opening for access to the product. A method for production of such a container is also described.
摘要:
A container is made of flexible sheet material, particularly for products with a solid consistency, obtained by successive folding and sealing of a sheet material. It is substantially parallelepiped-shaped. The container (1) has, at two of its opposite facing side walls (16), respective reinforcing plates (7) and is provided with a bottom seal (4), subsequently folded and sealed on the bottom (8) of the container, to strengthen it, a system for opening by means of a pull tab (6) being provided at the top of the container.
摘要:
A system is described for handling flat, hollow bodies, particularly frames destined to feed automatic packaging machines, according to which use is foreseen of hollow tubular cores (2) on which the frames (1) are inserted and retained by liftable tongues (10). The tubular cores (2) complete with frames (1) or loaders/magazines (25) are stored in rows placed one on top of the other inside container boxes (20), and can be used to load a feed unit (30) of a packaging machine, comprising a plurality of hollow columns (A,B,C,D), each forming an inner housing (31), accessible through a corresponding door (32) at the front, for stacking of the frames (1).
摘要:
A one-way degassing valve (4) for aromatic products, such as coffee and the like, comprising a valve body (5,6), a valve element (12) and a selective type filter (17, 170), preferably consisting of activated charcoal which allows the passage of low molecular weight gases, such as carbon dioxide, and retains the high molecular weight gases that constitute the product's aroma.
摘要:
Containers formed of a flexible sheet of material capable of being sealed for closing off the interior of the container from the ambient atmosphere. The sheet material is resistant to tearing. The container comprises a mouth portion including a peel strip or layer fixedly secured to the inner surface of the container and extending substantially the entire length of the mouth portion, with adjacent portions of the peel strip or layer being in releaseable engagement with each other. The engagement forms an air-tight interfacial seal which is readily openable by peeling the engaging portions of the peel strip or layer from each other to provide ready access to the interior of the container without tearing the sheet material forming the container.Some containers are formed in accordance with the method for applying the peel strips transversely across a web of sheet material and heat sealing the strips to the material at longitudinally spaced locations and thereafter severing the web into sections which are formed into the container. Other containers are formed by use of a peel layer on the entire inner surface of the container. The peelable interfacial seal for such containers is formed by heat sealing the same within a desired temperature range. The remaining seams of the container are permanent and are formed by heat sealing the same at temperatures in excess of those used in making the peelable seal.
