摘要:
A food-safe container (2) for liquids is composed of a tubular body (3) referable to a longitudinal axis (2a), and a neck (7) presenting a quadrangular base (16) fastened coaxially to an open top end (5) of the tubular body (3) afforded by a frustopyramidal connecting portion (6) of which the four tapered corner edges are pinched initially and left with four relative fins (22); the container (2) is formed by a machine (1) equipped with a folding and sealing or welding unit (24) including twin pairs of arms (26) by which the single fins (22) are folded flat against corresponding side walls (6a, 6b, 6c, 6d) of the connecting portion (6), and a pair of heat-sealers or ultrasonic welders (29) operating in conjunction with the arms (26), by which the fins (22) flattened against the respective side walls (6a, 6b, 6c, 6d) are secured in place.

A duct (1) applicable to a container (4) presents a connecting portion (9) with four substantially flat connecting surfaces (9a) and a internal bridging surface (13) by which the side walls (7a) of the container (4) are joined seamlessly to a spout (5) afforded by the duct (1); the bridging surface (13) is contoured in such a way that a flow of liquid food product can be directed through the spout (5) without becoming trapped and stagnating between the duct (1) and side walls (7a) of the container (4).
摘要:
A machine for packaging fiber material comprises feed means (2) supplying predetermined portions of fiber material (3) in an ordered succession, compacting means (4) by which the portions of fiber material (3) are compacted initially, a feed station (8) to which packs (9) are supplied for filling with the fiber material (3), a filling station (D) at which the fiber material (3) is inserted into the packs (9), and a closure station (E) located downstream of the filling station (D), at which the filled packs (9) are sealed. The machine further comprises fiber material (3) compressing and forming means (7) by which each of the portions of fiber material (3) is maintained in a state of compression downstream of the compacting means (4) for a prescribed interval of time, in such a way that the selfsame portion of fiber material (3) is caused to assume a compact geometry of tablet-like form prior to its insertion into the respective pack (9).
摘要:
A rotary assembly, for FFS (Form, Fill and Seal) machines, for ultrasound sealing a continuous tubular strip housing an orderly succession of products and travelling along a feed path extending through the sealing station; the rotary assembly having two rotors, which are located on opposite sides of the feed path, and rotate in opposite directions about respective axes; and at least one of the two rotors being fitted with at least one ultrasound sealing device, which cooperates at the sealing station with a corresponding anvil fitted to the other rotor with the interposition of elastic members.
摘要:
A container (1) for liquid products fashioned from at least one blank of multi-layer paper material comprises an essentially parallelepiped body (2) with four side walls (4, 5, 6, 7), and a top section (9) presenting four angled faces (4a, 5a, 6a, 7a) that converge toward a tubular element (17) providing a spout (15) from which to pour the liquid contents. The tubular element (17) also presents four tags (24) designed to interact with the top section (9); the tags function as anchors insertable between and weldable together with the corresponding edges (11) of the blank to form joined areas (12) serving as both closure and reinforcing elements in the finished container (1).
摘要:
Containers (2) for food products are manufactured employing a system that includes a feed station (4) supplying a succession of tubular elements (2a), and a heat sealer (10) positioned to close and secure a first open end (2b) of each tubular element (2a) that coincides with the base of the container. The sealing operation occurs at a station associated with a conveyor (3) consisting in a wheel (11) rotatable in a feed direction (B) along a path (P) passing both through the feed station (4) and through the station occupied by the heat sealer (10). The tubular elements (2a) are carried by radial elements (13) of the wheel (11) such as can be indexed between a first operating position, where the tubular elements (2a) are taken up from the feed station (4), and a second operating position in which the open end (2b) is offered to the heat sealer (10).
摘要:
A rotary unit, of an FFS (Form, Fill and Seal) machine, for ultrasound sealing a continuous tubular strip housing an orderly succession of products and fed along a feed path extending through a sealing station; the rotary unit having two substantially identical rotors located on opposite sides of the feed path, and which rotate in opposite directions about respective axes, and have respective pitch surfaces tangent to each other and to the feed path; and an ultrasound sealing head, forming part of one of the two rotors, cooperates at the sealing station with a corresponding anvil forming part of the other rotor, to close the tubular strip along a transverse seal line located at a respective portion of the tubular strip extending between two respective adjacent products.
