Definitions

  • the present invention relates to packaging bags for receiving, containing, and dispensing packaged articles. More particularly, the present invention relates to a packaging bag which is preferably flexible and has an expansion force release, end opening that assists in the removal of compressed articles one at a time.
  • Packaging bags composed of flexible polymer materials have been used for packaging various types of products, such as infant diapers, training pants, feminine care products and adult incontinence garments.
  • the bags allow packaging of the articles to create a carton-like look and configuration which facilitates transportation and display on retail shelves.
  • the bags typically include handles to facilitate the carrying of individual packages from the retail shelves, and can include mechanisms for providing an access opening in the package.
  • the present invention therefore provides a packaging bag having a partial expansion force release, end opening according to any one of independent claims 1, 2, 5 and 8. Further advantageous features, aspects and details of the invention are evident from the dependent claims, the description and the drawings. The claims are intended to be understood as a first non-limiting approach of defining the invention in general terms.
  • a packaging bag having a partial expansion force release, end opening for individually dispensing a compressed, stacked array of articles contained therein.
  • the packaging bag comprises a pair of side walls, a pair of end walls, and a top wall and a bottom wall, and a compressed stack of articles exerts an expansion force against the end walls.
  • a frangible line is formed in one of the end walls and, upon being broken, provides an opening in the end wall in which the opening is completely positioned within the end wall periphery. The opening partially releases the expansion force against the end walls so that the end walls still contain the articles in the bag, while the opening permits access to and removal of the articles one at a time.
  • a packaging bag having a partial expansion force release, end opening for individually dispensing a compressed, stacked array of articles contained therein.
  • the packaging bag comprises a pair of side walls, a pair of end walls, and a top wall and a bottom wall, and a compressed stack of articles exerts an expansion force against the end walls.
  • a frangible line is formed in one of the end walls and, when broken, provides an opening in that end wall.
  • the opening has a maximum height dimension and a maximum width dimension, and one of these dimensions is less than a respective height or width dimension of the end wall, so that the end walls still contain the articles in the bag when the frangible line is broken to form the opening.
  • a packaging bag having a partial expansion force release, end opening for individually dispensing a compressed, stacked array of articles contained therein.
  • the packaging bag comprises a pair of side walls, a pair of end walls, and a top wall and a bottom wall, and the compressed stacked array of articles exerts an expansion force against the end walls.
  • Each one of the articles has a height dimension, a width dimension, a top edge, a bottom edge, and a side edge.
  • a frangible line is formed entirely within one of the end walls and, when broken, provides an opening in that end wall.
  • a packaging bag having a partial expansion force release, end opening for individually dispensing a compressed, stacked array of articles contained therein.
  • the packaging bag comprises a pair of side walls, a pair of end walls, a top wall, and a bottom wall, and in which each end wall has a height dimension, a width dimension, a top edge, a bottom edge, and a side edge.
  • a compressed, stacked array of articles is contained in the bag and exerts an expansion force against the end walls.
  • a frangible line is formed entirely within one of the end walls and, when broken, provides an opening in that end wall.
  • Carrying loop 50 may further provide two generally opposed loop faces 54 and 56 (Fig. 2). Each loop face 54,56 can have at least one hand-grip opening 58 formed therein with the hand-grip openings configured to provide for a hand-suspension of bag 20.
  • Carrying loop 50 may optionally include an appointed separation section, such as frangible section 60 (Fig. 6), located at a selected, intermediate position between hand-grip openings 58.
  • Frangible section 60 is constructed and arranged to provide for a reconfiguration of the carrying loop 50 into separate, independently movable strap portions.
  • frangible section 60 of carrying loop 50 extends generally aligned with top edge region 28 of front panel 22, and is constructed with sufficient tensile load capacity to permit the arm-suspension of bag 20 while the bag is substantially filled with the selected articles.
  • compressed articles or similar terminology will mean that a stack of articles, such as articles 96 in Fig. 10, are compressed inwardly by a compression force at face surfaces 106 of articles 96 in a direction parallel to stack direction 100 so as to decrease the length dimension 91 of the originally, uncompressed articles.
  • compression packed or similar terminology describes the state or condition of articles 96 after they have been compressed and inserted into bag 20.
  • expansion force or similar terminology refers to that generally equal force exerted by the compressed articles 96 in a direction generally opposite and parallel to the compression force and against primarily end walls 110, 112. Naturally, all of the walls of bag 20 experience some degree of tension as a result of articles 96 exerting an expansion force primarily against end walls 110, 112.
  • Front panel 22 and back panel 32 may be composed of different materials, or may be composed of substantially the same type of material.
  • the material is a polymer film which is sufficiently flexible to assume a desired, generally hexahedral shape when the bag is substantially filled with articles.
  • the material should have sufficient strength to hold and contain the articles without breaking and without excessive bulging or stretching of the film material.
  • the film material may be composed of a polyethylene film or film laminate having a thickness of about 0.0635 millimeters (about 2.5 mils).
  • the film material may comprise a LDPE (low density polyethylene) film, a LDPE/LLDPE (linear low density polyethylene) film laminate, a LDPE/MDPE (medium density polyethylene) film laminate, a LDPE/HDPE (high density polyethylene) film laminate or the like.
  • LDPE low density polyethylene
  • LLDPE/LLDPE linear low density polyethylene
  • MDPE medium density polyethylene
  • LDPE/HDPE high density polyethylene
  • front panel 22 includes two opposed, generally parallel side edge regions 24 and 26.
  • the front panel 22 further includes a top edge region 28 which generally interconnects and runs substantially perpendicular to the side edge regions.
  • the front panel has a length dimension 70 and a height dimension 72. It is readily apparent that the panel length and height dimensions will vary depending upon the size and the desired configuration of the packaged articles.
  • Back panel 32 includes two opposed, generally parallel side edge regions 34 and 36.
  • the back panel further includes a top edge region 38 which extends substantially perpendicular to side edge regions 34 and 36, and generally interconnects the side edge regions.
  • Back panel 32 is generally coextensive with front panel 22 and is positioned in an adjacent, facing relation with the front panel. Thus, a major face surface of the back panel is located generally parallel to a major face surface of the front panel.
  • the two side edge regions 34 and 36 of back panel 32 are suitably interconnected with the correspondingly adjacent side edge regions 24 and 26 of front panel 22.
  • the interconnecting assembly of the front and back panels may be accomplished by various techniques well known in the art, such as adhesive bonding, thermal bonding, ultrasonic bonding, welding, and the like.
  • interconnection may be accomplished with inter-engaging mechanical fastening systems, such as sewing, stapling, riveting, and the like.
  • other component parts of bag 20 described in the present specification can be attached or otherwise connected together employing the above-described assembly techniques.
  • Top gusset member 52 is operably connected to the top edge regions 28 and 38 of front panel 22 and back panel 32.
  • Top gusset 52 may be integrally formed with either of front panel 22 or back panel 32, or may be integrally formed with both the front and back panels.
  • top gusset 52 may be a separate web of material which is assembled to top edge 28 of front panel 22 and top edge 38 of back panel 32.
  • the top gusset is typically composed of a flexible polymer film material, such as the material employed to construct front panel 22 or back panel 32.
  • top gusset 52 can be composed of a LDPE film laminate having a thickness of about 0.0635 millimeters (about 2.5 mils).
  • top gusset 52 is integrally formed with both front panel 22 and back panel 32. Accordingly, a unitary web of material is selectively folded to form top gusset 52 and front 22 and back 32 panels.
  • the top gusset extends from fold line 64 to fold line 66 and includes a medial fold line 68.
  • Fold line 64 provides a line of demarcation between front panel 22 and top gusset 52.
  • fold line 66 provides a line of demarcation between back panel 32 and the top gusset.
  • Fold line 68 extends substantially down the center of top gusset 52, and generally bisects the top gusset to define gusset panel sections 74 and 76, which are substantially equal in size.
  • the top gusset has a gusset length dimension 70, and has an unfolded, extended width which substantially corresponds to the desired package width 122 (Fig. 11).
  • top gusset 52 is a separate member assembled to front panel 22 and back panel 32
  • the top gusset member may be composed of a material which is different than the material comprising the front and back panels.
  • the longitudinal, lengthwise edge regions of the top gusset member will be connected by suitable fastening mechanisms to the front and back panels along the regions thereof which generally correspond to fold lines 64 and 66.
  • the downward end of the diagonal bond intersects its respective side panel bond 37 at a point located approximately 1.905 cm (0.75 inch) above gusset fold line 68.
  • the side panel bond has a width of about 0.952 cm (about 0.375 inch).
  • Periphery 53 of line 42 thus lies fully within the periphery of end wall 110 and is spaced-apart from walls 108, 114, 116, 118.
  • Another way of describing these limits of frangible line 42 is with respect to an individual article 96.
  • upper limit 43 of frangibility with respect to Fig. 7, is spaced below top edge 102 of an article 96
  • lower limit 41 of frangibility is spaced above bottom edge 104 of an article 96
  • lateral limits 39 of frangibility are spaced inwardly of respective side edges 98.
  • the periphery 53 of frangible line 42 lies fully within the periphery of face surface 106 of the article 96 immediately adjacent end wall 110.
  • upper limit 43 of frangibility is spaced from top edge 102 and/or top wall 108 (i.e., the end wall top edge) a distance from about 0 percent to about 50 percent of the height 93 (Fig. 10) of an article 96; lower limit 39 of frangibility is spaced from bottom edge 104 and/or bottom wall 114 (i.e., the end wall bottom edge) a distance from about 0 percent to about 90 percent of the height 93 of an article 96; and lateral limit 39 is spaced inwardly from a respective side edge 98 and/or side wall 116, 118 (i.e., the end wall side edges) a distance from about 0 percent to about 40 percent of the width 92 of an article 96.
  • frangible line 42 is not a complete closed-loop line.
  • hinge portion 113 serves as a hinge-like connection between the flap 109 of material located within the bounds of frangible line 42 and the other portion of the bag material outside the limits of frangible line 42.
  • hinge portion 113 serves to hingedly maintain connection between flap 109 of broken material and the remaining portion of end wall 110.
  • frangible line 42 may assume other geometric or non-geometric designs.
  • Fig. 8 illustrates frangible line 42 in the shape of an oval with its longitudinal axis generally parallel to top and bottom walls 108, 114.
  • line 42 with its oval shape can have its longitudinal axis generally perpendicular to walls 108, 114.
  • Line 42 can be formed in other shapes, such as a circular, racetrack, and the like.
  • frangible line 42 again defines a rectangular-like shape.
  • the upper limit 43 of frangibility is essentially coincident with top wall 108 and the lower limit 41 of frangibility is essentially coincident with bottom wall 114.
  • the lateral limits 39 of frangibility are spaced inwardly from side walls 116, 118 or the vertical edges of end wall 110.
  • frangible line 42 may, for example, be provided by partially cutting or otherwise thinning through the thickness of the bag material in a predetermined pattern, providing a selected pattern of perforations along the appointed sections of the bag, providing a desired pattern of stress-fatigue weakening along the appointed sections of the bag, or the like.
  • frangible line 42 is provided by a line of perforations in which there can be approximately 2-10 perforations per 2.54 cm (per lineal inch) of frangible line 42.
  • frangible line 42 is composed of alternating slits and lands. The slits are approximately 0.3175 cm (1/8 inch) long and substantially aligned along the intended direction of frangibility. The lands also have a length dimension of 0.3175 cm (1/8 inch), as measured along the intended direction of frangibility.
  • Handle web 44 (or handle web 45) is suitably connected to front panel 22 and back panel 32 to provide a bag carrying system.
  • the handle web is composed of a flexible web material, such as a polymer material composed of a MDPE/LDPE film laminate or a HDPE film, which has sufficient tensile strength and sufficient load capacity to support the weight of a filled bag while the bag is suspended by the handle web.
  • handle web 44 is composed of a MDPE/LDPE film material having a web thickness of about 0.10 mm (about 4 mils).
  • Handle web 44 (Fig. 1) has a mounting portion 46 for connecting the handle web to the front and back panels.
  • Mounting portion 46 of handle web 44 is constructed to extend substantially along the entire length of the top edge regions 28 and 38 of front panel 22 and back panel 32, respectively. As a result, mounting portion 46 can be attached, for example, with bonds 62, along substantially the entire top edge periphery of the filled package. Such a configuration can more widely spread and distribute the carrying stresses induced by using the handle web to transport a filled bag.
  • mounting portion 46 of handle web 44 may be bonded along an extent which is less than the entire length of the top edge regions of the front and back panels. Preferably, however, mounting portion 46 extends the entire length of the top edge regions of the front and back panels.
  • Handle web 44 can further include a strap portion 48 for providing a carrying loop 50.
  • the carrying loop is constructed to continuously bridge over top gusset 52 and to extend between front panel 22 and back panel 32 in a generally arched configuration.
  • carrying loop 50 can be arranged to provide for an arm suspension of bag 20 through the operation of loop 50.
  • carrying loop 50 may include an appointed separation region, such as frangible section 60, which is located and arranged at an intermediate position between the hand-grip openings.
  • the loop frangible section is constructed to provide for a separation and reconfiguration of the carrying loop into generally independently movable strap portions. The resultant strap portions are then capable of being individually repositioned to completely disconnect the original bridging between the front and back panels produced by carrying loop 50.
  • the carrying loop is substantially devoid of any seams or bonding lines which might excessively interfere with the desired separation of the appointed separation region.
  • Loop frangible section 60 defines a direction of separability (e.g., frangibility) which extends generally parallel with top edge region 28 of front panel 22.
  • the separability of section 60 may be provided by any suitable treatment which reduces the strength of section 60 relative to the remainder of carrying loop 50.
  • the frangibility of section 60 may be provided by selectively reducing the web thickness along section 60, by providing a line of perforations along the frangible section, by inducing a pattern of stress-fatigue weakness along the frangible section, or by a like construction.
  • loop frangible section 60 may be relatively weaker than the remainder of carrying loop 50
  • the frangible section is constructed with sufficient tensile load capacity to permit the arm-suspension of bag 20 while the bag is substantially filled with contained articles.
  • Strap portion 48 has a strap length and a strap width, and the loop frangible section 60 extends generally along the strap width. The strap length is selected to provide a loop size which is convenient for carrying while the bag is suspended from a user's arm through use of carrying loop 50. It will be readily apparent that the specific strap length will depend upon the final width dimension of a filled bag.
  • Bag 20 is typically filled through its bottom, and the bottom edge regions of the front and rear panels are folded and suitably bonded to close the bottom of the bag against the bottom portions of the articles in a conventional manner well known to the packaging art.
  • the resulting bag has a generally hexahedral shape, as representatively shown in Fig. 11.
  • Individual articles 96 generally define opposing side edges 98, a top edge 102, a bottom edge 104, and opposing face surfaces 106.
  • the individual articles are stacked upon their respective face surfaces 106, and when the stacks are compression packed, surfaces 106 face along stack direction 100 of bag 20. Accordingly, the top edges 102 of the articles contact the top wall 108 of the package, the bottom edges 104 of the articles contact the bottom wall 114 of the package, the side edges 98 of the articles contact the package panels 22, 32, and the outermost face surface 106 of the end articles 96 contact end walls 110, 112.
  • stack array 90 is composed of a single stack of articles, it is readily apparent that the stack array may comprise a plurality of individual stacks.
  • the individual stacks may be arranged side by side, top to bottom, or combinations thereof as desired.
  • Stack array 90 is compressed along stack direction 100 to reduce the length dimension 91 of array 90 so as to fit within the length dimension 120 (Fig. 11) of the bag 20. Since articles 96 are resilient, the stack array 90 exerts an expansion force along stack direction 100 after the compressed stack of articles has been inserted into bag 20. This expansion force is restrained by the package walls, particularly end walls 110 and 112. As a result, the expansion force exerted by the compressed articles applies a tensile stress to the walls, and the applied stress generates a certain amount of resilient elastic strain or stretch against the walls. Accordingly, the bag material is suitably selected and sized to withstand and accommodate the stresses and strains produced by the forces generated by the compressed stack array 90 contained within the filled package.
  • the bag material is selected and sized such that it does not undergo excessive amounts of permanent, plastic deformation when stressed by the stacked array.
  • the major force of expansion of the packed articles acts in a direction generally parallel to stack direction 110 and thus against end walls 110, 112.
  • bag 20 in its filled package form has a package length 120, a package width 122, and a package height 124.
  • Medial portions of front panel 22 and back panel 32 form package side walls 116 and 118, respectively.
  • Longitudinal end regions of front panel 22 and back panel 32 form package end walls 110 and 112 with the bonding line of attachment 37 running along the end walls along the height dimension of the filled package.
  • Top gusset 52 becomes extended with the medial portion of the top gusset forming package top wall 108.
  • longitudinal end regions of top gusset 52 become folded and tucked into the interior of the package to form generally triangular-shaped tucks 126.
  • bag 20 is opened by breaking frangible line 42 to gain access via opening 111 to articles 96.
  • frangible line 42 is initiated by breaking lower limit 41 and then propagating the break or tear along frangible line 42 through lateral limits 39 and upper limit 43 and terminating at hinge portion 113, thus forming flap 109 (Fig. 13A).
  • the expansion force against end walls 110, 112 is only partially released because the remaining portion of end wall 110 continues to hold the stacked array of articles within the confines of bag 20 so that the articles 96 are not forcefully ejected through opening 111.
  • the user can insert a finger or thumb through opening 111 near hinge portion 113 and then on or over the top edge 102 of the first article 96. Thereafter, the user can use the finger or thumb to pivot or lever the top portion of article 96 through opening 111, as illustrated in Fig. 13C. The user then can grasp the top of article 96 and pull it out of bag 20 while the remaining articles 96 are maintained within the confines of bag 20 by end wall 110.
  • the user can simply insert a finger or thumb inside the opening created by the breaking of frangible line 42 and grasping the article side edge 98 in order to pivot or lever the side edge portion of an article 96 through the opening formed by breaking frangible line 42.
