DETAILED DESCRIPTION OF THE INVENTION

[0030] Referring to FIG. 1, a volatile material dispensing system 20 is illustrated. The dispensing system 20 includes a volatile material dispenser 22 and a display frame 24. The frame 24 is operable between first and second states to provide a user various manners of utilizing the present dispensing system 20.

[0031] FIG. 1 depicts the display frame 24 in the first state. A front face 26 of the display frame 24 comprises a first wall portion 28. The first wall portion 28 is substantially rectangular in shape and has a width of about 3.5 in. and a height of about 5 in. A cover 30 is provided within the front wall portion 28 and attached thereto by a perforated section 32 about a periphery of the cover 30. The cover 30 is substantially square except for an arcuately shaped portion that has been removed from an upper corner of the cover 30. The removed portion defines a slot 34. The cover 30 is substantially centered about the width of the front face 26 and is directed closer to a bottom end 36 of the display frame 24 than a top end 38 thereof. A hole 40 is disposed within the first wall portion 28 adjacent the top end 38.

[0032] The cover 30 overlies the dispenser 22 further illustrated in FIGS. 2-5. With reference to FIGS. 2 and 3, the dispenser 22 or cartridge comprises a blister 44, a peripheral flange 46, and an impermeable laminate 48 releasably adhered to the blister 44 and the flange 46. The blister 44 includes a non-porous permeable membrane 50 and a cup-shaped structure 52 or reservoir. The cup-shaped structure 52 includes a bottom wall 54 and four side walls 56 that in conjunction with the permeable membrane 50 act as a sealed reservoir to contain a volatile material 58. Illustratively, the cup-shaped structure 52 and the permeable membrane 50 are formed from clear and/or translucent materials, thereby allowing the volatile material 58 to be visible therethrough. The peripheral flange 46 is planar and is coupled to and extends outwardly from top edges of the cup-shaped structure 52. In one embodiment, the peripheral flange 46 extends outwardly from upper edges of the side walls 56 and is integrally formed therewith. The present dispenser 22 and the volatile material 58 are similar to those described in U.S. Patent Application Serial No. 10/881,816, the disclosure of which is herein incorporated by reference in its entirety.

[0033] FIG. 4 illustrates the dispenser 22 in a first condition. The dispenser 22 is completely or substantially full in the first condition, i.e., little or no volatile material 58 has diffused through the permeable membrane 50 because the impermeable laminate 48 has not been removed from the blister 44. There is substantially no diffusion of the volatile material 58 when the dispenser 22 is filled and the impermeable laminate 48 covers the permeable membrane 50. Illustratively, the impermeable laminate 48 is removed from the blister 44 by a user grasping an end of the impermeable laminate 48 and peeling it off the blister 44. A tab 60, extension, or other means for grasping may be included as an extension of the impermeable laminate 48 to aid in removal of same. The extension may be at the corners, ends, and/or on the surface of the impermeable laminate 48.

[0034] Following removal of the impermeable laminate 48, the dispenser 22 begins to transition from a full or first condition (FIG. 4) to an empty or second condition (FIG. 5). There may be a small amount of the volatile material 58 that remains in the blister 18 and the dispenser 22 will still be considered to have reached the second condition. As the volatile material 58 diffuses through the permeable membrane 50, the permeable membrane 50 slowly collapses upon the bottom wall 54. With reference to FIG. 5, following diffusion of the volatile material 58 across the permeable membrane 50 there is less volatile material 58 contained within the dispenser 22. Substantially no new air enters the dispenser 22 subsequent to diffusion of the volatile material 58. The result of this is a pressure gradient across the permeable membrane 50, with a higher pressure existing in the ambient air than the pressure in the dispenser 22. The pressure gradient causes the ambient air to exert a net positive pressure upon the dispenser 22, which presses the permeable membrane 50 against the remaining volatile material 58 and ultimately the bottom wall 54.

[0035] With reference again to FIG. 1, a portion of the impermeable laminate 48 is visible through the slot 34. The dispensing system 20 is activated by removing the cover 30 from the display frame 24, such as is depicted in FIG. 6. The cover 30 is removed by grabbing a portion of the cover 30 within the slot 34 and pulling the cover 30 outwardly away from the display frame 24. When a sufficient force is exerted upon the cover 30, same will tear away from the first wall portion 28 and provide a substantially square opening 62. The opening 62 in one embodiment has length and width measurements of about 2.876 in. The impermeable laminate 48 is viewable and accessible through the opening 62. The impermeable laminate 48 extends a distance substantially coterminous with a width and height of the opening 62. The impermeable laminate 48 is removed by grasping a portion of the laminate 48, such as the tab 60, and pulling the laminate 48 off of the blister 44. Removal of the impermeable laminate 48 allows the dispenser 22 to transition from the first condition (FIG. 4) to the second condition (FIG. 5), thereby allowing for the volatile material 58 to be dispersed into the atmosphere.

[0036] A rear face 64 of the display frame 24 is depicted in FIG. 7. The rear face 64 comprises second and third wall portions 66, 68, respectively. The second wall portion 66 is substantially rectangular in shape and has a width of about 3.5 in. and a height of about 1 in. The third wall portion 68 is integrally connected to the second wall portion 66 and has a width of about 3.5 in. and a height of about 4 in. A second opening 70 is provided within the third wall portion 66. The second opening 70 is substantially square-shaped and has length and width dimensions substantially equal to or greater than the length and width dimensions of the cup-shaped structure 52 of the blister 44. In one embodiment, the second opening 70 is dimensioned to be smaller than the opening 62 of the first wall portion 28 and has length and width measurements of about 2.313 in. The second opening 70 is centered about the width of the rear face 64 and is disposed closer to the bottom end 36 of the display frame 24 than the top end 38. The hole 40 extends through the second wall portion 66 adjacent the top end 38 of the display frame 24. The cup-shaped structure 52 protrudes through the second opening 70. In other embodiments, the cup-shaped structure 52 partially protrudes into the second opening 70 or is substantially aligned therewith. FIG. 8 provides a side elevational view that illustrates the extent to which the cup-shaped structure 52 extends through the second opening 70 in the present embodiment. The distance the cup-shaped structure 52 extends through the second opening 70 may be modified by adjusting the dimensions of the dispenser 22 and/or the display frame 24. For example, one or more of the first wall portion 28, the second wall portion 66, the third wall portion 68, or a fourth wall portion 72 may be manufactured from a material having a different thickness to adjust the degree to which the cup-shaped structure 52 extends though the second opening 70.

[0037] The dispensing system of FIGS. 1 and 6-11 depict the dispensing system 20 in the first state. The first state is characterized by a having the first, second, third, and fourth wall portions 28, 66, 68, 72 disposed in a substantially parallel manner to each other. Portions of the dispenser 22, such as the bottom wall 54 and the impermeable laminate 48, are also parallel to the first, second, third, and fourth wall portions 28, 66, 68, 72. Typically, a cord or other member is strung through the hole 40 and the dispensing system 20 is hung from a support structure (not shown). In a different embodiment, the dispensing system 20 is propped against a wall or other surface or may be laid upon a support surface. There are numerous manners of deploying the dispensing system 20 in the first state that users may employ.

[0038] Referring now to FIGS. 9-12, the dispensing system 20 is disposed in the second state. With particular reference to FIG. 12, the rear face 64 of the display frame 24 is shown. The third wall portion 68 is rotated about a hinge 74 to extend outwardly from the remaining portions of the display frame 24. In the second state, the cup-shaped structure 52 does not extend through the second opening 70 and is no longer aligned therewith. The third wall portion 68 acts as a support member or foot member to assist in propping up the dispensing system 20 from a support surface 76. FIG. 11 illustrates that the dispensing system 20 takes on a substantially inverted V-shape in the second state with the second wall portion 66 and portions of the first wall portion 28 extending therefrom at an angle. A bottom end 78 of the third wall portion 68 and a bottom end 80 of the combined first and fourth wall portions 28, 72 exert forces upon the support surface 76 to maintain the dispensing system 20 in an upright position in the second state.

[0039] The third wall portion 68 is actuable between the first state and a plurality of positions that define the second state. Prior to placing the dispensing system 20 in the second state, the third wall portion 68 is juxtaposed with the fourth wall portion 72 and substantially parallel therewith in a first position. The dispensing system is placed in the second state by rotating the third wall portion 68 about the hinge 74. Rotation of the third wall portion 68 causes same to be angled from the fourth wall portion 72 and placed in a second position. The third wall portion 68 may be angled anywhere between about 1 degree to about 180 degrees to place the dispensing system 20 in the second state. Illustratively, the angle of the third wall portion 68 is between about 20 degrees and about 70 degrees.

[0040] Regardless of whether the dispensing system 20 is in the first or second state, the permeable membrane 50 of the dispenser 22 is directed substantially away from the rear face 64 of the display frame 24. The volatile material 58 is therefore emitted into the atmosphere without obstruction, thereby allowing for more efficient diffusion of the volatile material 58. The permeable membrane 50 is also viewable from the front face 26 of the dispensing system 20. A user may therefore determine the level of the volatile material 58 remaining in the dispenser 22 without exercising great effort.

[0041] FIGS. 13 and 14 illustrate one type of blank 82 that may be used to manufacture the present dispensing system 20. The blank 82 may be manufactured from paperboard or the like and die cut into the appropriate shape. FIG. 13 depicts a front side 84 of the first wall portion 28 with the removable cover 30 and the hole 40. FIG. 14 depicts a rear side 86 of the first wall portion 28. The second wall portion 66 is attached to a first end 88 of the first wall portion 28 by a hinge 90 or a fold line. The second wall portion 66 also includes the hole 40 and front and rear sides 92, 94, respectively. The third wall portion 68 is attached to the opposite end of the second wall portion 66 at the hinge 74 or a fold line. The third wall portion 68 includes the second opening 70 and front and rear sides 96, 98, respectively. The fourth wall portion 72 is attached to a second end 100 of the first wall portion 28 by a hinge 102 or a fold line. The fourth wall portion 72 includes a third opening 104 similar in dimensions to the second opening 70 and front and rear sides 106, 108, respectively.

[0042] The dispensing system 20 is assembled by inserting the cup shaped structure 52 of the dispenser 22, which is not shown in FIG. 13, through the third opening 104 from the rear side 108 of the fourth wall portion 72. The peripheral flange 46 of the dispenser 22 is hot sealed onto portions of the rear side 108 of the fourth wall portion 72 surrounding the third opening 104. The fourth wall portion 72 is rotated about the hinge 102 to position the rear side 108 of the fourth wall portion 72 substantially flush with the rear side 86 of the first wall portion 28. The rear side 108 of the fourth wall portion 72 and the rear side 86 of the first wall portion 28 are hot sealed together. When the fourth wall portion 72 is positioned in such a manner the impermeable laminate 48 of the dispenser 22 is centered behind the cover 30 of the first wall portion 28. The second wall portion 66 is folded about the hinge 90 so that the holes 40 are aligned. The rear side 94 of the second wall portion 66 is similarly hot sealed to the rear side 86 of the of the first wall portion 28. The remaining third wall portion 68 lies substantially flush against the fourth wall portion 72 so that the rear side 98 of the third wall portion 68 is juxtaposed against the front side 106 of the fourth wall portion 72.

[0043] The blank 82 may comprise any other type of paper based material or a different material such as plastic. Different materials such as plastics may be useful in humid environments that would otherwise be harmful to paper based materials. Further, portions of the blank 82 and the dispenser 22 may be adhered to one another by an adhesive or different type of glue. The display frame 24 itself may also be shaped in a decorative manner for aesthetic effect or provided with varying colors and/or pictures. FIGS. 15 and 16 depict one such dispensing system 120, wherein like reference numerals are assigned with respect to similar structure utilized in the dispensing system 20. The dispensing system 120 is characterized by curved side walls 122 of the first, second, third, and fourth wall portions 28, 66, 68, 72. The dispensing system 120 is also provided with a string 124 that is threaded through the hole 40. The string 124 may be used to support the dispensing system 120 from a support surface such as a rod or door knob. The present embodiment may also be provided without the cover 30 to omit material that has to be discarded. FIGS. 15 and 16 are illustrative of the variations that may be found in other embodiments with respect to the size and shape of various wall portions.

[0044] FIGS. 17 and 18 depict a different embodiment of a dispensing system 220 similar to the dispensing system 20. However, the dispensing system 220 differs in that a retention member 222 is provided on the fourth wall portion 72 adjacent the bottom end 80 of the combined first and fourth wall portions 28, 72. The retention member 222 comprises a resilient curved member that is partially cut away from the fourth wall portion 72 and that is angled outwardly toward the third wall portion 68. When the dispensing system 220 is in the first state, a portion of the bottom end 78 of the third wall portion 68 is retained within the retention member 222. Retention of the third wall portion 68 within the retention member 222 causes the bottom end 78 of the third wall portion 68 to be held against the fourth wall portion 72. Removal of the third wall portion 68 from the retention member 222 transitions the dispensing system 220 from the first state to the second state. The retention member 222 provides the dispensing system 220 with enhanced means for maintaining the dispensing system 220 in the first state. For example, the retention member 222 may prevent an inadvertent state transition from an outside force acting on the dispensing system 220 or from movement of the third wall portion 68 due to over-flexing of the hinge 74. It is envisioned that other types of retention members may be used that are of varying shape, number, or placement. Further, a retention member may be integral with the display frame as shown with respect to FIGS. 17 and 18 or may be a separate structure attached to the display frame.

[0045] In a different embodiment, the dispensing systems 20, 120, 220 are provided with openings and dispensers of varying shapes. For example, the dispenser 22 may be fashioned in the shape of a rectangle or other design, such as a snowflake or an animal. Further, multiple dispensers may be provided in a single dispensing system 20, 120, 220 with different or similar volatiles disposed therein. It is also envisioned that a re-usable adhesive may be used to hold some or all of the first, second, third, and fourth wall portions 28, 66, 68, 72 and the dispenser 22 together so that the dispenser 22 may be replaced as opposed to replacing the entire dispensing system 20, 120, 220 after the volatile material 58 has expired. In yet another embodiment, the dispensing systems 20, 120, 220 may be placed on a side thereof so that the bottom and top ends 36, 38 of the dispensing systems 20, 120, 220 do not touch a support surface. Rather, portions of the first, second, third, and fourth wall portions 28, 66, 68, 72 defining either a left or right side of the dispensing system 20, 120, 220 are disposed adjacent the support surface. The third wall portion 68 is still rotated about the hinge 74 to transition between first and second states and offers a user a different way of operating the present dispensing systems 20, 120, 220 as disclosed herein. Those skilled in the art will appreciate the numerous variations that may be made with respect to the present disclosure and which is intended to be captured by the present disclosure. Industrial Applicability
