CONTAINER AND METHOD OF RESTRICTING THE OPENING OF A CONTAINER
A container, the container having a wall, the wall comprising a front panel and a rear panel spaced apart at opposing edges thereof by side parts attached by edge folds to the front and rear panels, each side part comprising front and rear gusset panels linked by a gusset fold, the front panel, rear panel and side parts each including a container portion and a closure portion, the container portions extending from a closed base of the container to the closure portion, the closure portions each including a rim defining an opening of the container, the container being arranged such that the gusset panels are located between the front and rear panels and can overlie one another, the container further comprising at least one locking corner defined in one of the front and rear panels and an associated gusset panel by locking folds which extend transverse to the edge fold from the intersection of the edge fold, the closure portion and the container portion to the rim, the locking corner being foldable such that the locking corner can be arranged between the front and rear gusset panels.
PACKAGE MADE OF A LAMINATE MATERIAL
A package accommodating a plurality of absorbent articles is described. The package has a plurality of surfaces, including a first pair of opposing surfaces each having a seam, wherein at least one of the seams is a closing seam, wherein the closing seam extends along a direction of a width of the package, wherein the closing seam comprises opposing closing gussets; a second pair of opposing surfaces each adjacent the first pair of opposing surfaces; a front surface and an opposing rear surface, each of the front surface and rear surface being adjacent to each of the first pair and second pair of opposing surfaces, wherein the first pair, second pair, front and rear surfaces define an interior compartment of the package. The package is a laminate having a polymeric layer and a paper layer, the polymeric layer being disposed at least in the closing seam.
Machine and method for producing bags
A machine for producing bags includes a station for forming a tube, which forms a band of transversely perforated flexible material into a tube, a holding station for retaining the tube, a folding station for forming a bottom at the end of the tube, a folding roller having a folding blade for folding a flap at the end of the tube and a tear-off bar for pinching the tube against the drum, the folding station and the holding station being configured to jointly exert a traction on the tube and detach a portion of the tube. The tear-off bar is disposed behind the folding blade, the machine controlling the rotation of the folding station to synchronize the drum with the front of the tube.
Package made of a laminate material
A flexible gusset package containing a plurality of items is described. The package has a front surface having no seam; a rear surface opposite the front surface; a first surface adjacent the front and rear surfaces; a second surface having a closing seam and being opposite the first surface; an opposing pair of third and fourth surfaces respectively adjacent the first and second surfaces, the third and fourth surfaces having a first and second side seams, respectively; a pair of side gussets located in the third and fourth surfaces, respectively; and a pair of closing gussets located in the second surface, wherein the surfaces cooperatively define an interior compartment of the package, wherein the package is a laminate having a film layer facing the interior compartment and a paper layer, and wherein the second surface includes an area of the film layer where the closing seam is formed.
BAG MAKING APPARATUS AND BAG MAKING METHOD
A bag making apparatus includes an intermittent feed device for feeding sheet panels, an adjustment device for detecting upper and lower thresholds for a length of the sheet panels included in a section from a first drive roller pair to a second drive roller pair, a movement device for moving a processing device and a sensor together as a movable group in the longitudinal direction of the sheet panels. The movement device moves the movable group upstream in response to the adjustment device detecting the upper threshold and moves the movable group downstream in response to the adjustment device detecting the lower threshold. If the movable group is moved, the intermittent feed device determines an intermittent feed distance based on a moving distance of the movable group in addition to output from the sensor and feeds the sheet panels by the determined distance using the first drive roller pair.
Draw tape bag
The bag may include a draw tape that may be used to cinch closed the opening of the bag. The draw tape has at least one stretched elastomeric strip attached to the draw tape in an extended condition. The draw tape may be smaller in size than the bag sidewalls. The draw tape may include an elastic characteristic, such as patterned ribs. In one embodiment, the roll of bag is kept under tension to maintain the elastomeric strips in a stretched condition.
Closing system for packages with closeable interlocking element
A system and a method for closing, in an automated way, at least one package having a reversibly closeable interlocking element comprising a first complementary element and a second complementary element extending between two extremities. The system includes a pressing element, configured to press the first complementary element against the second complementary element by sliding between the two extremities, and a counteracting element, configured to stop the second complementary element when the pressing element presses the first complementary element against the second complementary element, in such a way that the first complementary element and the second complementary element interlock with each other along their entire length.
Device and method for producing bags
A device for production of bags that preferably consist mostly of paper includes a perforation device for cross perforation of a material web, a tube formation device for formation of a tube from the material web, a first separation device to separate individual tube sections, a device to form a bottom on one of the ends of the tube section, and a second separation device with which individual material sections can be torn off from the tube sections or bags.
Methods and apparatus for forming, filling and sealing film containers
A container (100) is formed by being folded and sealed on one of a multiplicity of male dies (12) of an apparatus (10). The male die (12) with the container (100) placed thereon is inserted into a female die (120). The female die (120) retains the container (100) while the male die (12) is removed therefrom. Lips (110-112) of the container (100) are sandwiched against the female die (120) while product is pushed thereon to prevent collapse of the container (100). The multiplicity of male dies (12) are relatively moveable by rotating about an axis (20) relative to the female die (120).
Method for manufacturing sheet material container
A method for manufacturing a sheet material container where the sheet material container includes one or a plurality of sheet members including a main-body forming sheet member that has an outer film layer and an inner film layer which are mutually stacked, a containing region that accommodates contents, and a container body that is configured from the main-body forming sheet member and that surrounds the containing region, and the main-body forming sheet member having a main-body sealing portion, which is an attached region between the outer film layer and the inner film layer, and a non-attached region where the outer film layer and the inner film layer are partially not attached, and further having a filling portion where a filler is enclosed between the layers of the outer film layer and the inner film layer in the non-attached region.
