  • DETAILED DESCRIPTION OF THE DRAWINGS
  • Referring to FIGS. 1-3, a pouch 20 includes opposed walls 22, 24 sealed along edges 26 and 28. The walls 22, 24 are integral with one another at a bottom edge 30, or alternatively, are sealed to one another at such location. The walls 22, 24 define a mouth 31 therebetween. Movement of a slider 32 along opposed closure profile strips 34, 36 in the direction of an arrow C from a first end 38 to a second end 40 closes the mouth 31 of the pouch. In this regard, the slider 32 includes opposed wall portions 42 a, 42 b that pinch and thereby interlock profiles 44, 46 of the strips 34, 36 together as is well known in the art. Movement of the slider 32 in the direction of an arrow O opens the pouch. In this regard, a separator finger 48 of the slider 32 separates the profiles 44, 46 during movement in the direction of the arrow O.
  • Suitable end stops 49 are provided at the ends 38, 40 of the pouch 20, wherein the end stops 49 prevent the slider 32 from sliding off the ends 38, 40 of the pouch 20. The end stops 49 may be regions of the strips 34, 36 that are heat sealed together and deformed. Referring also to FIG. 3A, the strips 34, 36 may include rails 50 a, 50 b that guide movement of the slider 32. The strips 34, 36 may further include flange portions 52 a, 52 b that are sealed to the pouch walls 22, 24, respectively.
  • FIG. 1 shows a plurality of indentations 53 a-53 e disposed in the strip 34 adjacent the second end 40 of the pouch 20. It should be noted that any number of indentations may be provided adjacent the second end 40 suitable to provide an audible and/or tactile indication of pouch closure when a user slides the slider 32 over the indentations 53. In pouches lacking the indentations 53, a user may have difficulty readily determining whether the slider 32 is moving in a direction to close the pouch 20 or a direction to open the pouch 20. With such conventional pouches, the user might have to visually inspect whether such pouch is closing or has been closed. By positioning the indentations 53 a-53 e adjacent only the second end 40, a user is provided with a tactile indication of pouch closure as the slider 32 passes over the indentations 53 en route to the second end 40. This can be highly advantageous for persons who are blind or have other visual impairments and cannot visually inspect the pouch 20 to determine whether the pouch is closed. In addition, the indentations 53 are also advantageous even for visually able persons considering such persons need not even look at the pouch 20 to determine whether the pouch 20 is closing or has been closed. The strip 36 may also include indentations 54 a-54 e similar or identical to the indentations 53 a-53 e and that function in like manner thereto.
  • Referring to FIG. 3A, the indentations 53 may be formed in an exterior surface 60 of the strip 34. The indentations 54 may likewise be formed in an exterior surface 62 of the strip 36. FIG. 3A shows indentations 70, 71 formed in surfaces 72, 73 of the profiles 44 and indentations 74, 75 formed in surfaces 76, 77 of the profiles 46. Movement of the slider 32 toward the second end 40 causes the opposed wall portions 42 a, 42 b to exert pressure on the strips 34 and 36. The pressure varies as the slider 32 moves over the indentations 53, 54, 70, and/or 71 to provide an indication of closure. FIG. 3B shows an alternative embodiment lacking the indentations 70, 71, 74, 75 shown in FIG. 3A.
  • Preferably, although not necessarily, the indentations 53 or 54 are disposed between a midpoint M of the bag and the closing end 40. The indentations 53 or 54 are preferably spaced a minimum distance D1 from the end 40 and a maximum distance D2 from the end 40, D2 being preferably less than M. Spacing the indentations 53 or 54 from the end 40 allows the user to know whether the slider 32 is moving in the closing direction prior to the slider 32 actually reaching and contacting the end 40.
  • D1 could optionally range anywhere between about 0.75 inches (about 1.9 cm) and about 3 inches (about 7.6 cm), depending upon the size of the bag. More preferably, D1 could range between about 1 inch (about 2.5 cm) and about 2 inches (about 5.1 cm), and even more preferably between about 1 inch (about 2.5 cm) and about 1.5 inches (about 3.8 cm). D2 could optionally range anywhere between about 1 inch to about 3.5 inches. Preferably, D2 measures about 1.8 inches (about 4.6 cm). It should be noted that in bags having end stops such as the end stops 49, the indentations 53 or 54 could measure a minimum distance D3 measured from an inner periphery or boundary 79 of the end stop 49. In addition, the indentations 53 or 54 could measure a maximum distance D4 from the boundary 79. D3 could range between about 0.3 inches (about 0.8 cm) to about 2 inches (about 5.1 cm), and D4 could range between about 1.5 inches (about 3.8 cm) to about 3.5 inches (8.9 cm).
  • FIG. 4 illustrates a pouch 80 having a series of indentations 82 disposed generally along the length of the strip 34 and/or 36 as well as a plurality of indentations 86 a-86 e disposed only adjacent one end 90 of the pouch 80. The indentations 86 may have a characteristic different than the indentations 82 to provide a user with a tactile or audible indication of closure. For example, the indentation 86 e shown in FIG. 4B has a depth greater than the indentation 82 shown in FIG. 4A as measured from a surface 92 of the strip 34. It should also be noted that the indentations 86 may be spaced apart from one another differently than the indentations 82 to provide an indication of pouch closure when the slider 32 passes over the indentations 86.
  • Referring to FIG. 5, a roll 100 of closure material 102 includes opposed closure strips 104, 106 similar or identical to the strips 34, 36 of the foregoing embodiments. One or both of the strips 104, 106 includes portions 108 having indentations similar or identical to the indentations 53, 54, 70, 71, 74, or 75. The centerlines of the portions 108 are spaced apart by a distance d, equal to the width of the bag 20 as measured between the ends 38, 40. The closure material 102 is joined to bag wall material, and the closure material 102 and bag wall material are severed to form a bag such as the bag 20 having the one of the portions 108 adjacent the closing end 40. The distance d may be any suitable distance such as at least about 3 inches (about 7.6 cm). Alternatively, the distance d could be up to about 20 inches (about 50.8 cm) or more, depending upon the desired bag size. Regions 112 are disposed between the portions 108. The regions 112 could optionally include further indentations such as the indentations 82 having one or more characteristics different than the characteristics of the indentations of the segments 108.
  • INDUSTRIAL APPLICABILITY
