Definitions

  • the invention relates to a process for packing absorbent articles in a pre-made flexible bag and subsequently creating a handle element on-line.
  • Flexible bags are widely used to pack many different types of consumer products. For instance, disposable diapers are typically packed in plastic bags. The resultant bags are generally cumbersome and difficult to carry.
  • handle elements are disposed on the outer surface of the flexible bags. It has been customary to provide separate handle elements of cardboard, moulded plastic or other suitable materials that are glued, stapled or heat welded to the bag.
  • US 4,252,269 teaches a bag of polymeric plastic material that has an opening at one end and a gusset at the opposite end. Within the gusset, a handle is welded to the front and rear panels of the bag along a fold line.
  • US 5,054,619 refers to an easy open flexible bag containing one or more stacks of flexible articles that comprises a longitudinally oriented carrying handle, which is formed independently of the bag.
  • US 5,026,173 describes a plastic bag having a side panel with a carry grip area in which a carry strip portion is located.
  • the carry strip portion is formed between carry grip apertures or easily breakable weakening lines.
  • the carry strip is coplanar with the side panel of the plastic bag and does not require seals of any kind.
  • Protective and reinforcement strips are provided underneath the carry grip apertures in order to protect the contents of the plastic bag from external contamination.
  • GB 1 575 921 teaches a bag provided with a carrier handle means where the handle is not located in loose flap members protruding from a sealed top panel, but in a flap participating in the wrapping of the articles.
  • US 4,913,693 provides a bag that includes a side-to-side continuous handle, which is formed from pieces of material that make up the sidewalls of the bag and a closed top formed from a separate piece of material.
  • DE 2 051 833 describes a means of producing a package for hygienic articles comprising two strips of plastic, one wider than the other.
  • the preferred production method consists of first forming a tube around the articles to be packed, then welding transversely to separate the tubes or packages while at the same time cutting the packages successively from one another.
  • the resultant package may contain a handle and a tear-off opening.
  • the handle lies between the welding seam used to seal the package shut and an additional seam, which is present for stability purposes.
  • a further object of the present invention is to provide a strong handle element mounting using suitable reinforcements and effective sealing techniques.
  • a pre-made flexible bag for flexible articles is provided.
  • Flexible articles are introduced into the flexible bag through an area corresponding to the top panel, which is subsequently sealed at its top panel. At least one flap protruding from the top panel is left attached.
  • the flap comprises a grip area and a grip area perimeter.
  • the flexible bag is pre-made before the introduction of the flexible articles and a handle element is shaped from the flap protruding from the top panel, the handle element comprising a handle element perimeter.
  • the preferred embodiment comprises two flaps.
  • the handle element comprises a seal running along the handle element perimeter. In order to allow fingers or hands to wrap around the handle, a grip area is formed.
  • the reinforced handle element can comprise flaps that are sealed together in the entire area of the handle element except for the grip area or the flaps are further reinforced at the handle element perimeter or the flaps comprise a seal surrounding the grip area perimeter or the flaps comprise a seal abutting the entire grip area perimeter.
  • Figure 1 is a front view of a pre-made flexible bag comprising a handle element made on-line.
  • Figure 2 is a front view of the various design configurations existing for the handle element of the pre-made flexible bag.
  • Figure 3 shows six different embodiments of sealing design configurations that are suitable for the handle element of the pre-made flexible bag.
  • the term "pre-made” refers to a bag in which the front, back, top, bottom and side panels are all interconnected.
  • grip area describes the area designed for gripping that is either cut, punched or scored out.
  • grip area perimeter represents the edge of the grip area.
  • handle element perimeter represents the edge of the handle element.
  • FIG. 1 shows a pre-made flexible bag 10 comprising flexible articles.
  • the flexible articles may comprise disposable absorbent diapers, sanitary articles, incontinence pads or briefs, bandages and the like.
  • the flexible articles are typically compressed to between 20 and 70 percent of their uncompressed volume and may be oriented either with all their waist features directed upwards towards the top panel 11 of the flexible bag 10 or with all their waist features directed downwards towards the bottom panel of the flexible bag 10 or the flexible articles may be alternated.
  • the flexible bag 10 is preferably made from conventional flexible polymer such as polyethylene or oriented polypropylene and the film caliper ranges from 30 to 120 micrometres.
  • the flexible bag 10 comprises a top panel 11 , a bottom panel, a front panel, a back panel and a pair of side panels, which are all interconnected according to means known in the art.
  • the pre-made flexible bag 10 to be used for containing the flexible articles is supplied either on wickets or on rolls, wickets being preferred.
  • the flexible bag 10 is sealed at its top panel 11 after introduction of the flexible articles, leaving attached at least one flap 12 , which protrudes from the top panel 11 of the flexible bag 10 .
  • the preferred embodiment comprises two flaps 12 . These flaps 12 represent excess trim material.
  • a handle element 13 is then shaped from the flaps 12 , and comprises a handle element perimeter 16 .
  • the handle element 13 can combine both curved and straight portions as is depicted in Figure 2.
  • the base of the handle element 13 can lie along a portion of the top panel 11 as is visible in embodiments (1), (2) and (4) of Figure 2 or the base of the handle element 13 can run along the entire length of the top panel 11 as is visible in embodiment (3) of Figure 2.
  • the formation of the handle element 13 is preferentially carried out during or shortly after the top panel 11 has been sealed.
  • the key features of the handle element 13 are the grip area 14 , the grip area perimeter 15 and the handle element perimeter 16 .
  • the grip area 14 can be formed on-line by either cutting, punching or scoring out the desired shape, which is suitable for gripping by the end user, namely the consumer. Alternatively, grip holes can be cut, punched or scored out of the flaps 12 . Several grip holes, preferably three or four, may be present and they can also be pre-made at the bag suppliers.
  • the grip area perimeter 15 and the handle element perimeter 16 follow the contours of the selected shapes for the grip area 14 and the handle element 13 , respectively.
  • the handle element 13 is capable of sustaining bag loads ranging from 2.5 to 4 kilograms without causing deformation or failure when being carried by the end user, namely the consumer. It is preferred that the base of the handle element 13 run along the entire length of the top panel 11 (for example, refer to embodiment (3) in Figure 2) such that the handle element 13 can better support the bag load and lead to improved stability.
  • Figure 3 shows six different embodiments of sealing design configurations that are suitable for the handle element 13 .
  • the base of the handle element 13 comprises a seal 17 , which is either the complete seal 17 or a portion of the seal 17 arising from the closure of the top panel 11 of the flexible bag 10 .
  • a seal 17 runs along the handle element perimeter 16 .
  • the flaps 12 are sealed together in the entire area of the handle element 13 except for the grip area 14 .
  • the flaps 12 are further reinforced at the handle element perimeter 16 .
  • the third embodiment comprises the first embodiment and further comprises seals 17 that are located in the corners lying closest to the seal 17 of the base of the handle element 13 and the seal 17 running along the side of the handle element perimeter 16 . It is feasible to place approximately one to three seals 17 per corner, the form of the seals 17 being either straight or curved.
  • the fourth embodiment comprises the first embodiment plus a seal 17 surrounding the grip area perimeter 15 .
  • the seal 17 is preferably located a distance ranging from 5 to 25 millimetres from the grip area perimeter 15 and typically the seal 17 follows the contours of the shape selected for the grip area 14 .
  • the fifth embodiment similarly comprises the first embodiment plus a seal 17 abutting the entire grip area perimeter 15 .
  • the sixth embodiment similar to the third embodiment, further comprises reinforcements at the handle element perimeter 16 . More specifically, the sixth embodiment comprises both the first and fifth embodiments plus diagonal seals 17 that extend from a location on the seal 17 running along the outermost part of the handle element perimeter 16 to a location on the seal 17 of the base of the handle element 13 .
  • the seals 17 in all cases preferably range from three to four millimetres in width although any width is possible.
  • the sealing can be performed using conventional heat sealing techniques or alternatively, techniques such as ultrasound, crimping or pressure bonding can be employed.
  • Heat sealing techniques tend to weaken the flaps 12 in the immediate vicinity of the sealed area due to the concentration of heat along the seal 17 .
  • the other techniques rely less on heat and more on pressure and thus do not weaken adversely the flaps 12 .
  • the sealing pattern can comprise crosses, dashed lines, v-shapes, u-shapes, inverted shapes, to cite but a few of the many possibilities existing. The effect of the pattern results in an improved distribution of heat over a wider area and consequently, a stronger supporting film around the seals 17 .
