Definitions
- the present invention relates to a dispensing apparatus adapted for serially dispensing plastic bags from wound rolls which are joined along perforated severance lines.
- the customer occasionally has one hand occupied holding the selected fruits or vegetables or some other item which precludes using both hands to separate the end bag from the wound roll.
- the customer usually attempts to jerk the bag from the wound roll without holding the adjacent bag and/or the wound roll. This usually results in damage to the end bag and/or causes the wound roll to over spin on the fixed shaft.
- This free spinning of the wound roll about the fixed shaf ⁇ causes an excessive number of bags to be reeled from the wound roll.
- These unwanted bags must then be either rewound onto the wound roll or separated therefrom resulting in possible damage and/or waste.
- the purpose of providing produce bags adjacent the fruits and vegetables in the produce department is to assist customers with packaging of the selected items.
- a plastic bag dispenser which is both conveniently positioned and properly oriented to allow only one bag to be dispensed at a time.
- U.S. Patent No. 5,219,424 and related U.S. Patent No. 5,135,146 to Simhaee which disclose a dispenser having a tongue which engages the separation line between the bag at the end of the wound roll and the next bag.
- a finger is provided on the upstream side of the tongue with a gap being formed between the finger and the tongue such that as the bag is separated, a portion of the front edge of the next bag is held in the gap, thereby holding the bag in position for the next user.
- a separating means is preferably located on the container to engage the severance line of the plastic bags and separate the end plastic bag from the next bag on the wound roll to provide for serial dispensing of the plastic bags.
- a self-threading means is preferably located on or attached to the container for threading the plastic bags from the wound roll received in the container onto the separating means.
- the self- threading .means provides for easy threading of a new or replacement wound roll onto the separating means.
- the self-threading means comprises a pair of inwardly facing flanges which extend generally transverse to the pair of sides and which are lateral spaced apart to define an opening through which are directed the advancing plastic bags to allow for easy dispensing thereof.
- the separating means comprises a separating tongue which extends outward from the bottom and is shaped so as to engage the severance line located between the plastic bags.
- the separating tongue of the separating means is preferably located slightly above a horizontal axial alignment with the bottom to ensure that the separating tongue easily contacts the severance line of the plastic bags at the desired location.
- the container in its preferred embodiment includes a mounting means which allows the container to be mounted in a wide variety of positions on a wide variety of solid surfaces while maintaining the container in its desired orientation. This ability of the mounting means to be mounted on any number of solid surfaces allows for the device to be attached to displays, counters, refrigeration units, etc., throughout a store or other establishment.
- the container be formed in a unitary construction to simplify the production and improve the strength of the container. It is also beneficial to have portions of the bottom and the sides be cut away to provide easy access to the wound roll for purposes of replacement, reduce the overall weight of the device, and limit the build up of any debris within the container. In the unlikely event that the end of the wound roll is not retained by the separating means, the cut aways allow easy rethreading of the wound roll. The shape and location of the cut aways, in cooperation with the container, provide clear visual access to approximately eighty percent of the wound roll. Therefore, locating the end of the wound roll for rethreading is greatly simplified.
- the preferred orientation of the container is such that the wound roll is biased against the bottom and the pair of flanges to improve the self-braking of the wound roll and limit overspinning thereof as the plastic bags are serially separated from the wound roll .
- the separating means be angled downward away from the bottom. This becomes more important as the wound roll becomes smaller in diameter as the bags are removed therefrom. Continuously biasing the wound roll against the flanges and the bottom creates a pinching effect, preventing the wound roll from overspinning as the bags advance toward the separating means. In addition, it also helps to retain the wound roll within the container.
- This self-braking arrangement of the container minimizes the inconvenience and waste associated with the excess bags caused by overspin of the wound roll.
- a high friction material such as rubber
- a smooth materials such as Teflon ®
- the bracket has a first end, a second end and a center portion extending therebetween. Its is beneficial to have the first end be bent at an angle approaching 90° relative to the center portion while having the second end be bent at an angle approaching 45° relative to the center portion. It is also beneficial to have the bent first end and second end project away from the center portion on opposite sides of the longitudinal axis thereof.
- Such a configuration of the bracket enables the container to be mounted in a plurality of positions while maintaining the desired orientation of the container. It is desirable to provide the first end of the bracket with a first bracket aperture, the second end with a second bracket aperture, and the center portion with a third bracket aperture.
- first, second, and third bracket apertures will preferably cooperate with a bottom aperture, defined in the bottom, and a conventional fastener to thereby attach the bracket to the container.
- the other end of the bracket is mounted by means of a conventional fastener to the desired solid surface.
- the center portion ideally has the third bracket aperture located adjacent the first end to increase the number of positions in which the container can be mounted.
- Fig. 1 is a perspective view of a dispensing apparatus for bags in accordance with the present invention
- Fig. 2 is a view similar to that of Fig. 1 showing the wound roll with only a few bags remaining thereon;
- Fig. 3 is a cross-sectional view taken along line 3-3 of Fig. 1;
- Fig. 4 is an end view showing a plastic bag being fed along a threading slide in accordance with the present invention
- Fig. 5 is a perspective view of the mounting bracket in accordance with the present invention.
- Figs. 6-11 are a series of cross-sectional views showing the cooperation between the mounting bracket and the container for mounting the container to a solid surface in a plurality of positions.
- the apparatus 10 includes a container, generally indicated at 12 and a mounting bracket, generally indicated at 22.
- the container 12 has a unitary construction formed from a pair of opposed sides 14, a pair of flanges 16 extending generally transverse to the sides, a bottom 18 positioned below the sides, providing support therefor and a separating means or tongue 20 extending outwardly from the bottom 18.
- the container 12 is adapted to receive a wound roll of plastic bags AA, which is formed of a continuous roll of flexible bags AA, such as plastic, joined along perforated severance lines 24.
- the plastic bags AA are intended for use as produce bags in supermarkets or food markets, for carrying fruit and/or vegetables. It is to be understood however, that the apparatus 10 may be utilized for dispensing any number of different types of bags AA, which may be used for any particular use while remaining within the spirit of the invention. It is important that the bags which are chosen to be used in accordance with this invention are sufficiently flexible so as to be packaged on a wound roll.
- the container 12 of this embodiment has a very open configuration, relying on the cooperation between the bottom 18, the sides 14, the flanges 16, and the orientation of the container (see Figs. 6-11) , as determined by the mounting bracket 22, to retain the wound roll within the container.
- the size of the container 12 corresponds to the wound roll of plastic bags AA to be received.
- the container 12 shown in Figs. 1-11 has a solid construction, to the extent that the sides 14, the flanges 16 and the bottom 18 are formed of solid panels. It is to be understood, however, that the container 12 may also have a very open construction and remain within the spirit of the invention. Almost any material can be used for the container 12 so long as the container 12 is capable of retaining a wound roll AA and cooperating with the mounting bracket 22.
- the container 12 may be constructed of wire or mesh.
- the mounting bracket 22 mounts the container 12 to a surface XX, preferably solid, in any one of a plurality of different positions.
- the mounting bracket 22 has a first end 26, a second end 28, and a center portion 30.
- the first end 26 is bent at an angle of approximately 90° from the longitudinal axis of the bracket 22.
- the second end 28 is bent at an angle of approximately 45° from the longitudinal axis of the bracket 22.
- the first end 26 and the second end 28 of the bracket 22 are bent in opposite directions from the longitudinal axis of the bracket.
- This opposed relationship of the first end 26 and the second end 28 relative to the center portion 30 of the bracket 22 allows the container 12 to be mounted in a wide variety of positions, while maintaining the desired orientation.
- the desired orientation of the container 22 will be described in detail below.
- the bracket 22 defines a first bracket aperture 32 located at the first end 26, a second bracket aperture 34 located at the second end 28 and a third aperture 36 located adjacent the first end.
- the bottom 18 of the container 12 has a bottom aperture 38 which selectively cooperates with one of the first, second or third bracket apertures (32, 34 and 36, respectively) by means of a conventional fastener, such as the nut(s) and bolt(s) 40 shown in Figs. 1-3 and 6-11.
- a second set of nuts and bolts 42 is used to mount the bracket to the solid surface XX. It is to be understood that other types of fasteners may be used to mount or secure the bracket 22 to the solid surface XX and/or the container 12 and remain within the spirit of this invention.
- the desired orientation of the container 12 is such that the wound roll, regardless of its size (see AA' ' ' in Fig. 2 for a small wound roll caused by having only a few bags remaining thereon) is biased against the flanges 16 and the bottom 18.
- the container 12 is oriented approximately 45° from horizontal. In this orientation, the juncture of the bottom 18 and the opposed sides 14, which are joined at an angle approaching 90°, form the lower most point of the container 12.
- the bottom 18 and/or the portions of the sides 14 and/or the flanges 16 adjacent the bottom with a high frictional coating, such as rubber.
- a high frictional coating such as rubber.
- Teflon ® a smooth, low friction material
- the weight of the wound roll AA itself also helps, at least initially, with preventing overspin. As the size of the wound roll decreases, the weight of the wound roll becomes less of a factor in preventing overspinning.
- each of the pair of opposed sides 14 has a generally square shape which cooperates with the bottom 18, to retain the wound roll.
- a corner of the square shape of each sides 14, remote from the flanges 16, has been cut at an extended 45° angle to reduce the weight of the container 12.
- first cutouts 44 are defined in each of the sides 14 to also reduce the weight of the container 12 and to provide easy access to the wound roll . These cutouts 44 assist in the ease of replacing wound rolls to be received within the container 12.
- the sides 14 are also provided to limit lateral movement of the wound roll as it is unwound. The sides extend a sufficient distance upward from the bottom 18 to contain the wound roll.
- the bottom 18 has corresponding second cutouts 46, which are contiguous with the first cutouts 44, to also reduce the overall weight of the container 12 and prevent any foreign objects from collecting inside the container.
- the first cutouts 44, the second cutouts 46, the opening between flanges 16 and the open top of the container 12 provide- easy visual access to approximately 80% of the wound roll. The visual access allows an individual to quickly locate the end bag AA' , if it is not retained on the separating means 20, for purposes of rethreading the end bag.
- the cutouts 15 are generally rectangular.
- cutouts 15 may take any shape desired so long as the above-referenced objectives are met.
- the purpose of this downward configuration is to continuously bias or pinch the wound roll against the flanges 16 and the bottom 18, especially when the wound roll is small.
- the reduced weight of the smaller wound roll would otherwise either overspin and/or travel up the inclined bottom 18, as the end bag AA 1 is removed from the wound roll.
- the separating means 20 then inclines slightly and forms at its free end a hook 48, to engage the severance line 24 between the end bag AA 1 and the next bag AA 2 , to allow the end bag to be separated from the wound roll.
- the hook 48 is positioned slightly above the horizontal plane of the bottom 18 to ensure easy engagement with the severance line 24 between the plastic bags AA. It is to be understood that the separating means 20 and its associated hook 48 may take on other related shapes and orientations, so long as the separating means easily engages the severance line between plastic bags AA. As illustrated in Figs. 1, 2 and 4, the flanges 16 combine to form a generally rectangular configuration. The adjacent surface of each flange 16 is cut at an angle to form a self-threading slide 50 therebetween. The two flanges 16 are spaced apart a sufficient distance so as to form an opening 52 therebetween, which is contiguous with the separating means 20.
- edges are rounded, to allow the advancing plastic bags AA to easily pass through the opening without damaging or obstructing travel of the bags.
- the wound roll is inserted such that the plastic bags AA unwind from the bottom of the wound roll .
- the wound roll of this embodiment does not need to be mounted on an axle. Rather, the wound roll is simply placed within the container and allowed to rotate freely. If desired, an axle may be provided within the container 12, to rotationally support the wound roll. It is also possible to place the wound roll within the container so that the plastic bags AA unwind from the top of the wound roll.
- the end bag AA 1 is pulled upward from the bottom of the wound roll toward the flanges 16 along the threading slide 50.
- the end bag AA 1 slides down the self-threading slide, all the while beginning to fold into itself, so as to have a generally U-shaped configuration as may be seen in Fig. 4.
- the bag will slide around the rounded edges of the self-threading slide 50, passed the opening 52 and onto the separating means 20, as shown in Figs. 1, 2 and 4.
- the end bag AA 1 advances on its predetermined path toward the hook 48, the bag will unfold along the separating means 20.
- the end bag AA 1 To remove the end bag AA 1 from the container 12, an individual or customer grabs the end bag with one hand and pulls the bag in a generally horizontal fashion away from the container 12. As shown in Fig. 3, the end bag continues to be pulled along its predetermined direction of travel, so that the perforated severance line 24 between the end bag AA : and the next bag AA 2 , will line up and engage the hook 48. This will ensure that the end bag will easily separate from the wound roll, while advancing the next bag AA 2 a sufficient distance beyond the container 12 to allow for its easy withdrawal.
- the plastic bags AA may be removed from the container 12 and separated from the wound roll with the use of only one hand, while ensuring that the next bag AA 2 can be easily grasped for removal .
- the bottom 18 and/or the sides 14 and/or the flanges 16 may be treated with other materials or provided with a textured surface to achieve the desired frictional surface.
