摘要:
A first embodiment of the packing film is a four-layered laminate film in which the following films are laminated in that order: a first oriented plastic film formed as an outer surface layer and provided with a first coarse surface portion, an aluminum foil or paper sheet, a second oriented plastic film provided with a second coarse surface portion which is overlapped with the first coarse portion, and a non-oriented plastic film formed as an inner surface layer. A second embodiment of the packing film is a three-layered laminate film in which the following films are laminated in that order: an oriented plastic film formed as a first surface layer and provided with a coarse surface portion, an aluminum foil, and a non-oriented plastic film formed as an inner surface layer. The oriented plastic film forming the outer surface layer is backed at its coarse surface portion by a thin surface layer and laminated to the aluminum foil through a binder layer.

A second embodiment of the packing film is a three-layered laminate film in which the following films are laminated in that order: an oriented plastic film formed as a first surface layer and provided with a coarse surface portion, an aluminum foil or paper sheet, and a non-oriented plastic film formed as an inner surface layer. The oriented plastic film forming the outer surface layer is backed at its coarse surface portion by a thin surface layer and laminated to the aluminum foil through a binder layer. A third embodiment of the packing film is three-layered laminate film having the same layers as in the second embodiment, and the oriented plastic film is laminated to the aluminum foil through a binder having a large amount of high solid component. When a packing bag and a package body are formed by using each of the packing films mentioned above, an area formed with the coarse portion serves as a portion from which the tearing is started.

The present invention relates to a device of regulating a running position of unsealing tape for packing film, in which in the normal operation unsealing tape runs on a linear normal running position disposed between projecting portions and by being guided by the projecting portions and while being in contact therewith, if the unsealing tape runs on the outside of an annular groove by being shifted to either side in the width direction, as a result of a relative movement of the annular groove in the direction reverse to the rotational direction of the regulating roller with the rotation of the regulating roller, the unsealing tape gradually enters the annular groove by being guided by corner portions and on the side of openings produced by separating portions and while being in an abrasive contact therewith, thereafter, the unsealing tape is drawn to the normal running position by being guided by approaching portions and while being in contact therewith and finally the unsealing tape is returned to the normal running position by being brought into contact with the projecting portions.

A tamper evident container assembly includes a container body having a bottom wall and peripheral side wall, the side wall terminating in an outwardly curled rim. A reusable lid includes a top wall portion and a depending skirt portion, the depending skirt portion constructed of spiral wound stock and having a free end, a major peripheral portion of the free end tucked under the upper rim and upwardly into engagement with the side wall, with a minor peripheral portion of the free end left untucked to thereby provide a gripping area to facilitate tearing and removal of the tear strip. The depending skirt portion is further provided in a lower portion thereof with a line of weakening extending annularly about the skirt portion to thereby define an annular removable tear strip inclusive of the free end, with the line of weakening lying on the rim, between upper and lower edges of the rim. Apparatus for forming the assembly includes a device for pressing a lower portion of the depending skirt portion of the lid under and into engagement with the rim of the container to form a curl about a major peripheral portion of the lid while leaving a minor peripheral portion uncurled while simultaneously forming a vertical slit in the lower portion of the depending skirt portion at an interface between the curled and uncurled portions to thereby simultaneously form a grip tab. Another device is provided for orienting the container to a predetermined rotational position prior to securing the lid. A related method of securing the lid to the container is also disclosed.

In the production of packs with outer wrappers which have a tear-open strip (12), the latter or continuous material strips (18), for the purpose of severing the tear-open strips (12), are provided with printing, markings (24), etc. Moreover, the film webs (13) are preferably provided with markings, printing or printed marks (25). Sensing elements help to detect the relative positions on account of said printing and the drive of the film web (13) and/or of the material strip (18) is controlled accordingly.
