Multi-roll pet waste bag organizer and dispenser

Abstract

A wall-mounted, vertical holder, organizer and dispenser for pet waste bag rolls. Pet waste bag rolls come in standardized sizes wound about a spool, each bag separated from the next by a serrated transversal line. These rolls can be fed horizontally from the top of the dispenser to remain held and organized in the dispenser in a stacked configuration. The dispenser facilitates a bag being separated from the bottom-most roll, pulled through a wedge and chute located near the base on the front of the dispenser, and torn off for use without dislodging the bags from the dispenser or the dispenser from the wall. The wedge holds the next bag in the chute, ready for next use.

DETAILED DESCRIPTION

(10) Referring now to FIGS. 1-4 there is shown a device that organizes and dispenses individual pet waste bags from standardized rolls. The pet waste bags are typically manufactured in rolls wound about a spool, with serrated transversal lines for detachment from the adjoining bag. The device comprises a rectangular receptacle [1] with a front sidewall [2]; opposing left and right sidewalls [3 and 4] defining the width of the rectangular receptacle, the width being sufficient to accept the roll placed horizontally in the receptacle; a rear sidewall [5]; a bottom sidewall [7]; and no top sidewall, such that rolls of bags can be deposited horizontally into the receptacle as shown in FIG. 5A.

(11) On the front sidewall just above the bottom is a dispensing wedge [9], which serves as a dispenser of individual bags, holding each bag in the wedge as it is drawn through the wedge, and trapping a next bag in the wedge when the first bag is torn off along the perforated separation. In order to accomplish this, the wedge [9] is typically a solid three-dimensional wedge also comprising a vertical dispensing chute [25] of lesser width than the width of the wedge, the dispensing chute [25] being in open communication with the interior of the receptacle [1], thus enabling a bag to be pulled out from the interior of the receptacle through the chute. The wedge itself [9] is comprised of a base [20] protruding perpendicularly from the front sidewall [2] of the receptacle [1]; a tip [11] meeting the front sidewall [2]; and a curved wedge front defined by a curved hypotenuse [10] between the base [20] and tip [11] of the wedge [9], such that the depth of the wedge [9] near the base [20] is greater than the depth of the wedge near the tip [20]. The width of the wedge [9] is narrowest near the base of the wedge and slightly wider near the tip [11]. The shape of the wedge [9] means that as a result of a bag is drawn downward into and through the chute [25], the chute grips the bag, providing sufficient resistance for the user to tear the bag off of the roll at the perforation point.

(12) Furthermore, the structure of the wedge [9] permits the next bag to remain trapped in the chute after the outermost bag has been torn off from the roll [25], so that this subsequent bag can be readily accessed and torn free when needed. In the preferred embodiment, the dispensing chute [25] contains a dispensing aperture [12] comprised of a cylinder with width larger than that of the dispensing chute [25]. Said wider dispensing aperture [12] serves as a pressure release point for the bag trapped in the chute, which is critical to ensure that the roll of bags remains in a resting position at the base of the receptacle [1]. In the absence of the dispensing aperture [12], pressure on the bag currently trapped in the chute can cause the roll of bags to shift or slide up in the receptacle. The dispensing aperture prevents this upward slide and also facilitates the extraction and tearing of a bag from the roll.

(13) Furthermore, the dispensing chute [25], which stretches from the tip [11] to at or near the base [20], is in open communication with the front opening [13] in the front sidewall [2]. This front opening [13] is sufficiently wide to allow user access to the roll of bags in order to extract an outer bag, and pull it down and out through dispensing chute [25], as shown in FIG. 5B. Moreover, the front opening [13] narrows to meet the dispensing chute [25] tip [11] of the wedge, guiding the bag into the chute and gradually increasing the resistance force on the bag. With reference to FIG. 5A, when first dropping a bag roll [24] into the receptacle [1], the design facilitates the first bag being drawn down through dispensing slot [25] to permit easy extraction of the first bag at any time. The front opening [13] also allows the number of remaining rolls of bags to be seen through the front sidewall.

(14) Therefore, with reference to FIGS. 5A-5B, the guide wedge [9] facilitates easy removal of a bag by tearing at perforated edges that separate one bag from the next. The guide wedge [9] protrudes from the front of the receptacle, allowing the user to tear the extended bag from any angle, and it provides sufficient counterforce so that little force is required to tear the extended bag. Moreover, the guide wedge [9] provides sufficient stabilization to retain the next bag slightly emerged from the dispensing slot [25]. The guide wedge [9] also provides sufficient stabilization so that the tearing force does not jostle, dislodge or pry the device from its mounting position on a wall.

(15) The rear sidewall of the device has means for attaching to a vertical supporting surface such as a cabinet, a closet door, or any other convenient surface in the home, yard, office, play area, kennel, pool shed, recreation space, back door area, and the like. In the embodiment shown in FIGS. 1-7, the attachment means are holes [6] that can accept screws and stabilizers [21 and 22] as shown in FIG. 7. The holes [6] can also accept other instruments such as nails, which could affix the device to the wall or other surface. In another embodiment shown in FIG. 8, the means are adhesive panels [6a] that can be affixed to the wall. The adhesive could be two-sided tape or other form of adhesive having a peeling protective layer.

(16) With reference to FIGS. 5-6, the rectangular receptacle is dimensioned to receive at least one waste bag roll [24] and generally to receive a plurality of waste bag rolls in a stacked configuration. The preferred embodiment is dimensioned to hold several standardized pet waste bag rolls, and is therefore a vertical rectangle with length approximately 5 inches, width approximately 3 inches, and depth approximately 1 inches at the top of the receptacle, with the depth at the base of the receptacle being slightly more narrow than the depth at the top. This difference in depth has aesthetic purpose as well as increasing the depth at the base of the guide wedge, which extends at least inch from the base of the receptacle. Of course, these dimensions are exemplary and not intended to limit the scope of the invention. The dimensions of the guide wedge can differ based on the size of the bag rolls and the thickness of the bags. For instance, a shorter and/or shallower wedge may accommodate larger bags, while thicker bags may require a wider chute and aperture.

(17) In some embodiments of this invention, the front sidewall and bottom sidewall [7] connect to form a curvature [15] so that the cradled cylindrical waste bag roll [24] will rotate easily inside the device. By permitting the waste bag roll to rotate easily at the base of the receptacle, the curvature [15] further reduces tension from the bag that is trapped in the chute [25], further facilitating the bags to rest in the receptacle without popping up and away from the wedge [9].

(18) In some embodiments, the bottom sidewall [7] of the receptacle preferably comprises an exit opening [19] from which empty rolls can be removed, as shown in FIG. 6. Because the bottom-most roll in the receptacle will always become smaller as the bags are removed in succession to be used until only the spool of the roll remains, the exit opening [19] would have a width at least 1 mm less than the width of the spool of the roll. Thus when the roll is empty, the user only need push the spool up slightly in the receptacle through the exit opening in order to angle the spool and extract it through the exit opening. In some embodiments the two opposing sidewalls [3 and 4] may also comprise side openings [16 and 17] to facilitate removal, visualization, or rearrangement of bags.

(19) The bag dispenser may be made of material that can be repeatedly bent without fracturing, such as polyethylene, polypropylene, vinyl, nylon, rubber, various impregnated or laminated fibrous materials, various plasticized materials and the like, and in some instances aluminum or stainless steel.

(20) A method of using the present invention may include the following: A user attaches the device to a wall or other supporting surface using screws or adhesive, as shown in FIGS. 7-8. Then, as shown in FIG. 5A the user may load at least one waste bag roll [24] into the receptacle [1], so that a waste bag roll [24] is cradled at the base of the chute. For the first roll loaded into the device the user can also guide the first bag through the dispensing slot [25] so that it is ready to be dispensed. As seen in FIG. 5B, the first bag can then be torn from the dispensing slot [25] whenever the user is ready to use the bag. The guide wedge [9] will retain the subsequent bag in place, partially emerged from the dispensing slot [25], ready for the next use. When the roll is empty, it can be removed through the exit aperture [19], as shown in FIG. 6.
