摘要:
A tobacco or similar packing of the folding bag type, i.e. comprising a strip of sheet material which is folded about a transverse folding line offset from the middle of the strip so as to present a front panel having a free top edge and a bottom edge constituted by said folding line, and a rear panel extending upwardly from said bottom edge to beyond the top edge of the front panel, the side edges of the adjacent panels being joined so as to define a flat bag portion, the rear side of which is extended into a flap portion beyond the top of the bag portion, said flap portion being folded or adapted to be folded down along the front side of the bag together with the uppermost part of the bag portion, about a second transverse folding line underneath the top edge of the front panel, and being fastened or adapted to be fastened in a releasable manner to the exterior surface of said bag portion by means of adhering fastening means. According to the invention the said fastening means are constituted by a transverse zone of adhesive applied to the exterior surface of the bag portion at such a location that the top edge of the front panel, when the bag is folded about said second transverse folding line, is situated adjacent to said transverse zone of adhesive, preferably approximately along the middle line thereof, whereby the pouch is closable in a sealed manner.

A transfer unit for transferring objects from a starting position to a final position, preferably between two presses in a plate pressing line, comprises two carriages (4, 5) which are displaceable along supporting rails (2, 3) and are provided with rotatable gripping devices (9-12) to grip and hold the object during the transfer which can be effected with or without turning over at the same time. The turn-over device makes it possible to turn the object during transfer and comprises a turning arm (24), one end of which is mounted in the carriage (4, 5), and the other end of which supports a follower (25) for cooperation with a guide rail (26, 27) with an essentially V-shaped portion (32-34), along which the turning arm (24) is guided as it is pivoted. The essentially V-shaped portion (32-34) consists of two arcuate guide rail sections (32, 33), which each extend from an individual straight portion (28, 29) of the guide rail, the free ends of the arcuate sections being equidistant from a point ( 35) where the tangents from the free ends intersect, and a switch piece (34) which can be pivoted between two end positions, in which it forms a continuation of one or the other of the two arcuate guide rail sections (32 or 33). The switch piece (34) can be locked in each of the end positions by a blocking mechanism (42) which can be released as the follower (25) is inserted into the switch piece (34).

A sealed package is disclosed that includes a breachable bubble for opening the package in combination with at least one reclosable device. The reclosable device may comprise a pair of opposing interlocking members. The breachable bubble allows for the package to be easily opened while the reclosable device allows for the package to be closed once opened. The breachable bubble and the reclosable device can be preformed on opposing strips that are then incorporated into the package as the package is being formed.

A package and a process for forming the package are provided. The process may include providing a first flexible polymer film and a second flexible polymer film, sealing the first film and the second film together to form an enclosure and at least one tab area, and trapping fluid within a discrete portion of the tab area to form a breachable bubble. The enclosure may define an interior volume configured to receive a consumer product. Fluid trapped within a discrete portion of the tab area to form a breachable bubble may be sufficient to cause the bubble to breach upon application of minimal pressure by a user, separating a sealed portion of the first film from the second film.

Apparatus for transporting and handling piece goods (4), containing a stand; a transport rail (10) carried by the stand; a trolley (17) which can be moved along the rail (10) by a separate drive (19); and a gripping device (22) which is pivotally mounted on the trolley and contains structure to hold the piece goods (4). A rotatably journalled guide shaft (28) of non-round cross-section extends substantially parallel with the transport rail (10); and a follower (30, 31) is rotatably arranged on the trolley (17) and connected to the guide shaft (28) so as to be slidable therealong but torsionally rigid in a radial direction. The guide shaft (28) is rotated by a motor (29); and an angular rotation transmission (23-27) converts rotation of the guide shaft (28) to swinging movement of the gripping device (22).

摘要:
A plastic sheet packing or packing member of the flat folding bag type, primarily for pipe tobacco, the mouth opening of which is sealed in a welded manner enabling it to be opened without rupturing the sheet materials adjacent the mouth opening. The mouth is closed by a type of welding providing a good sealing effect though being releasable by mechanical pull to facilitate opening of the packing. The opposed surface portions of the mouth area may be welded direct to each other in this manner, or a separate, removable closing strip may be arranged along and across the mouth and secured by the releasable type of welding. This type of welding may require mutually different materials to be joined, and this is obtained either by the use of said separate strip or by using a sandwich sheet for the packing itself.
