FIELD OF THE INVENTION
The present invention relates to holders for displaying and dispensing items, and more particularly to a stacked assembly of disposable biohazard containment bags having a reinforced holder for use in displaying and dispensing such items.
BACKGROUND OF THE INVENTION
The inventor has patented various inventions related to displaying and dispensing disposable rain protection devices. See U.S. Pat. No. 6,065,233 for a display stand, U.S. Pat. No. 6,341,381 for a disposable rain hood, U.S. Pat. No. 6,389,723 for a stand for disposable rain protection devices, and U.S. Pat. No. 6,454,125 for a stacked assembly of disposable rain hoods, all of which are incorporated herein by reference. In general, these inventions involve suspending disposable rain protection devices from a stand for displaying and dispensing the devices.
One particular problem that the inventor has experienced with the foregoing designs for disposable rain protection devices is that the display holder that holds the disposable rain protection devices may tear under the repeated stress of pulling disposable rain protection devices in order to separate the devices from the display holder. A design for existing prior art display holders is shown as item 90 in FIG. 4. The display holder generally comprises a piece of paperboard, cardboard, other type of cardboard that is folded to form opposing flaps 96A and 96B. A stack of disposable rain protection devices 1 is attached to a lower end of the opposing flaps 96A, 96B. An aperture 92 passes through the opposing flaps 96A, 96B (FIGS. 3 and 4). As shown in FIG. 4, the display holder can be suspended from a display stand 200 by passing a prong 216 of the display stand through the aperture of the display holder 90.
Because of cost considerations in providing large volumes of disposable rain protection devices, the display holders 90 of such devices are typically made of paperboard, cardstock or other types of cardboard. Cardboard materials provide an optimal balance between tear resistance and economics of manufacture. However, cardboard materials, while generally tear resistant under the forces ordinarily encountered with this invention, are subject to tearing under certain circumstances, such as when excessive force is applied (for example, if a disposable rain protection devices does not tear away properly), after repeated stress from multiple pulls, or if the cardboard becomes wet. When a passerby pulls an individual disposable rain protection device in order to separate it from the display holder 90, stress is created between the prong 216 of the display stand 200 and the aperture 92. With repeated stress, such as when a dozen or more disposable rain protection devices are pulled and separated from the display holder 90, the display holder may tear at the aperture 92. Once a tear starts, it is likely to become larger. Continued removal of disposable rain protection devices may tear the aperture 92 to the point that the display holder, along with the disposable rain protection devices, falls off of the stand. Even in situations where the display holder does not tear entirely off of the display stand, tears may be unsightly, particularly to proprietors of businesses and public buildings.
The inventor has recently extended the concept of using stands to display and dispense disposable items to the field of disposable biohazard containment bags, but without the use of the reinforced holders described herein. Numerous biological (i.e, biohazardous) waste materials are generated in hospitals, doctors' offices, veterinarians' offices, research facilities, and the like. These waste materials may include items of dry or semi-solid material (e.g., pathological wastes, blood supply paraphernalia, dressings, gloves, gowns, and blood-soaked linen) and/or liquid waste (e.g., blood plasma, body fluid specimens, and discarded vaccines). These waste materials may include sharp items (commonly referred to in the medical arts as “sharps”), such as hypodermic needles, syringes, blood vials, scalpel blades, culture dishes, and broken and unbroken glassware that were in contact with biological material. Exposure to these waste materials prior to their ultimate disposal may result in undesired contamination and/or infections. In recent years, the additional risk of infection with the AIDS virus has intensified the need for a method of disposing of medical wastes with minimum risk of cross-contamination.
The foregoing biohazard wastes are typically disposed of in a particular type of bag known as a biohazard containment bag, details of which are shown in FIG. 15 and are described below. Biohazard containment bags have conventionally been dispensed from boxes. Applying the concepts of the above mentioned patents, the inventor has recently begun displaying and dispensing biohazard containment bags in a stacked assembly using the conventional unreinforced holder shown in FIG. 4. The present application is directed to applying the concept of a reinforced holder, discussed in pending application Ser. No. 10/109,012, to displaying and dispensing biohazard containment bags.
OBJECTS AND SUMMARY OF THE INVENTION
It is an object of the invention to provide an improved means for displaying and dispensing disposable biohazard containment bags for disposing of biological material.
It is another object of the invention to provide a reinforced display holder for displaying and dispensing disposable biohazard containment bags that is resistant to tearing.
It is yet another object of the invention to provide a reinforced display holder for displaying and dispensing disposable biohazard containment bags that is economical to manufacture.
These and other objects and advantages of the invention, as well as others, shall become apparent from the following general and preferred description of the invention.
Accordingly, a stacked assembly of disposable biohazard containment bags having a reinforced holder for displaying and dispensing disposable biohazard containment bags is provided that includes a display holder formed from a piece of cardboard folded upward along an upward fold and downward along a pair of downward folds to thereby form a pair of opposing display holder flaps and an integral reinforcement member including a pair of opposing reinforcement member flaps. Preferably, the reinforcement member flaps are fixedly attached to one another, are sandwiched between the display holder flaps, and depend downward from an upper portion of the opposing display holder flaps. The display holder flaps and the reinforcement member flaps preferably have at least one aperture sized to receive the bracket member of the display stand to permit the suspension of disposable biohazard containment bags from the display stand via the display holder. The disposable biohazard containment bags include a suspension portion extending from an edge and connected to the edge by a frangible perforation. Preferably, the devices are stacked, attached to one another by a fastening means passing through the suspension portions, and sandwiched between the lower portion of the opposing display holder flaps such that a disposable biohazard containment bag may be detached by pulling the device and breaking the frangible perforation.
In one preferred embodiment, the plurality of disposable biohazard containment bags are disposable bags for containing or packaging of biological materials (e.g., biohazardous waste). Each disposable bag may be characterized as having an open end for receiving biohazardous material and a closed end for preventing the biohazardous material from leaking from the bag. These disposable bags are preferably attached to the display holder via a suspension portion that is detachably connected to the open end of the bag by a frangible perforation, such that a selected disposable bag may be selectively detached from the suspension portion and the display holder by pulling the disposable bag relative to the display holder to thereby break the frangible perforation.
Methods of constructing and displaying the foregoing reinforced display holder and associated disposable biohazard containment bags are also provided.

PREFERRED EMBODIMENTS OF THE INVENTION
In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings which form a part hereof, and in which are shown by way of illustration specific embodiments in which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the present invention.
The present invention relates to a stacked assembly of disposable biohazard containment bags having a reinforced holder for displaying and dispensing the disposable biohazard containment bags. This application is a continuation-in-part of pending application Ser. No. 10/109,012, and will initially be described in terms of the general concepts described in the parent application. The specific embodiments of the present invention are described in Subsection (C) below.
FIG. 6 shows a preferred embodiment of a front view of a reinforced holder 701 for displaying and dispensing items 106, such as disposable rain protection devices, from a bracket member of a display stand. As shown in FIG. 6, the reinforced holder 701 of the invention comprises, generally, a display holder 90, a reinforcement member 700 (shown partially in phantom lines), an aperture 604 passing through both the display holder 90 and the reinforcement member 700. During use, items 106, such as a plurality of disposable rain protection devices, are removably attached to a lower portion 91 of the display holder 90. The invention will be described herein for use with three particular types of items: (1) disposable receptacles for umbrellas 106 (see subsection A below; FIGS. 6 and 10); (2) disposable rain hoods 1 (subsection B below; FIGS. 1-4, 8); and (3) disposable biohazard containment bags (subsection C below; FIGS. 15A and 15B).
As shown most clearly in FIG. 7, the display holder 90 has a pair of opposing flaps 96A, 96B. In a preferred embodiment, the display holder 90 is made from a sheet of cardstock, paperboard, or other type of card board, and the opposing flaps 96A, 96B are formed by folding the display holder 90 downward along downward folds 703A, 703B.
The reinforcement member 700 forms an integral part of the display holder 90 and is constructed of similar material. The reinforcement member 700 comprises a pair of opposing flaps 704A, 704B and is formed by folding the display holder 90 upward along upward fold 702, preferably into substantially equal halves. The reinforcement member 700 is sandwiched between the opposing flaps 96A, 96B of the display holder, as shown most clearly in FIGS. 7 and 8. In the embodiment shown in FIG. 6, the reinforcement member 700 is rectangular and is substantially the same length as the display holder 90.
A means 705 is provided for fixedly attaching the opposing flaps 704A, 704B of the reinforcement member 700 to each other. In FIGS. 7 and 8, the means comprises an adhesive substance 705, which is economical and contributes to the ease of manufacture. Other means of fixedly attaching the opposing flaps 704A, 704B of the reinforcement member 700, such as staples or thread and the like could also be used.
FIG. 13 shows the preferred embodiment prior to forming the opposing flaps 704A, 704B of the reinforced member 700 and the opposing flaps 96A, 96B of the display holder 90 from a single piece of cardboard. The opposing flaps 704A, 704B are formed by upwardly folding the display holder 90 along the upward fold 702. The upward fold is preferably perforated. In a preferred embodiment, the perforations of upward fold 702 are about 0.125 inches (about 0.3 cm) in length and are spaced to obtain about four perforations per inch. The opposing flaps 96A, 96B of the display holder 90 are formed by downwardly folding the display holder 90 along the downward folds 703A, 703B. Folds 703A, 703B run substantially parallel to the upward fold 702. Folds 703A, 703B are preferably perforated. In a preferred embodiment, the perforations of downward folds 703A, 703B are about 0.5 to 0.75 inches (1.2 to 1.9 cm) in length and are spaced about 0.875 to 1.125 inches (2.2 to 2.9 cm) apart.
As shown in FIGS. 6 and 8, the display holder 90 and reinforcement member 700 have at least one aperture 604 that passes through both of the opposing flaps 704A, 704B of the reinforcement member 700 and the opposing flaps 96A, 96B of the display holder 90. The aperture 604 is sized to receive the bracket member 216 of the display stand 200 to thereby permit the reinforced display holder 701 to be suspended from the display stand 200.
FIG. 14 shows an alternative embodiment of a reinforced holder 700 that is designed particularly for use with disposable rain hoods 1. The embodiment of FIG. 14 has two apertures 604, 604, such that the reinforcement member 700 can be used with the two-aperture display holder 90 shown in FIGS. 3 and 12.
As mentioned above, a plurality of items 106, such as disposable rain protection devices 1, 106, are removably attached to a lower portion 91 of the display holder 90. As shown in FIGS. 8 and 10, the reinforced display holder 701 of the invention is used to display the items 1, 106 by hanging or suspending such devices 1, 106 from a bracket member 216, 400. FIG. 10 shows a set or stack arrangement 101 of disposable receptacles for umbrellas 106 suspended from a wall mounted display stand bracket member 400. FIG. 8 shows a set or stack arrangement 4 of disposable rain hoods 1 suspended from the bracket member 216. FIG. 15 shows a set or stack arrangement of biohazard containment bags 106 suspended from the bracket member 216. Examples of preferred items that can be suspended from the reinforced holder 701 will now be discussed in further detail.
A. Stacked Assembly of Disposable Receptacles for Umbrellas Having a Reinforced Holder
In FIGS. 6 and 10, the disposable rain protection devices suspended from the display holder 90 are disposable receptacles for umbrellas 106. The receptacles are shown stacked together in a set 101, attached to the display holder 90 via securing means 105 such as staples, thread, and the like. The display holder is releasably attached to a stand via a prong 408 through an aperture 604. The holder 90 exhibits an increased ability to withstand pulling forces through the reinforcement 600 of the double folded material therein (shown in greater detail in FIG. 8, depicted in total as items 701, 702, 703A, 703B, 704A, and 704B). As shown most clearly in FIG. 10, each disposable receptacle for umbrellas 106 comprises an elongated bag having an open end 107A for receiving a wet umbrella and a closed end 107B for preventing water from the wet umbrella leaking from the receptacle. A set of large sized receptacles can be provided for large umbrellas, and a set of small sized receptacles can be provided for small umbrellas. As shown in FIG. 6, each disposable receptacle for umbrellas 106 is preferably attached to the display holder via a suspension portion 80. The suspension portion 80 is detachably connected to the open end 107A of the elongated bag 106 by a frangible perforation 108, such that a selected disposable receptacle 106 may be selectively detached from the suspension portion 80 and the display holder by pulling the disposable receptacle 106 relative to the display holder to thereby break the frangible perforation 108.
B. Stacked Assembly of Disposable Rain Hoods Having a Reinforced Holder
FIG. 1 shows a side view of a preferred embodiment of a disposable rain hood 1 of the type disclosed in applicant's U.S. Pat. No. 6,341,381, which is incorporated herein by reference. The rain hood 1 comprises generally, a pair of opposing flaps 2A, 2B, the flaps being composed of conventional plastic sheeting or other inexpensive rain impermeable material. In FIG. 1, flap 2A is shown partially folded back at a front-lower corner. The flaps 2A, 2B are attached to one another substantially along respective upper edges 10 thereof The flaps 2A, 2B are further attached to one another substantially along respective rear edges 30 thereof. The upper 10 and rear 30 edge attachments provide a rain-impermeable barrier along the upper 10 and the rear 30 edges of the disposable rain hood. With the flaps 2A, 2B sealed together in the foregoing manner, the disposable rain hood 1 has a substantially open front edge 40 and a substantially open lower edge 20. The open front 40 and lower edges 20 permit the disposable rain hood 1 to receive a head and torso of a user 100, as shown most clearly in FIG. 2. The pair of flaps 2A, 2B are preferably formed from a single lengthwise sheet of plastic. In the preferred embodiment shown in FIG. 1, the sheet is folded substantially along a width-wise centerline 10 thereof to thereby form the pair of lengthwise opposing flaps 2A, 2B. The sheet is preferably about 37 by 30 inches (94 by 76 cm) prior to folding, which forms an approximately 37 by 15 inch (94 by 38 cm) hood after folding. The fold 10 forms the upper edge 10 of the disposable rain hood 1, and the rear edge attachment 30 is preferably formed by heat sealing the rear edges 30 of the flaps to one another. Such heat sealing methods are well known to those of ordinary skill in the art, but as far as is known such heat sealing methods have not been applied to disposable rain hoods as described herein. FIG. 1 shows an example of a heat seal 32 sealing rear edge 30. In another embodiment, the sheet is folded substantially along a length-wise centerline 30 thereof to thereby form the pair of lengthwise opposing flaps 2A, 2B. In this embodiment, the fold 30 forms the rear edge 30 of the disposable rain hood, and the upper edge attachment 10 is formed by heat sealing the upper edges 10 of the flaps 2A, 2B to one another. Alternatively, the disposable rain hood 1 can be formed from a pair of lengthwise sheets 2A, 2B, the two sheets being sealed together, preferably by heat sealing, to form the upper 10 and rear 30 edge attachments.
As shown most clearly in FIG. 2, the apparatus of the invention 1 is preferably further provided with a head stop 8. The head stop 8 serves to properly position the head of a user 100 in the disposable rain hood 1. The head stop 8 further attaches the respective flaps 2A, 2B to one another. The head stop 8 extends downward substantially from the sealed upper edge 10 of the disposable hood and extends substantially parallel to an upper portion of the sealed rear edge 30. The head stop 8 is positioned a sufficient distance from the open front edge 40 of the disposable rain hood 1 to thereby permit the head stop 8 to function as a rear barrier for a back portion of the head of the user 100 while the rain hood simultaneously shields the head of the user 100 from rain. The head stop 8 is preferably formed by heat sealing the flaps 2A, 2B to one another along the desired position of the head stop 8. Alternatively, stapling, stitching, or the like could be used to form the head stop 8. The disposable rain hood of the invention 1 is also preferably provided with at least one hole 50 positioned substantially along the forward edge 40 of each of the flaps 2A, 2B. The holes 50 are positioned to permit the forward edges 40 of the disposable rain hood to be selectively held together either by fingers of the user 100 or by a tie (e.g. string or a twist-tie) passing through the holes (the tie taking the place of fingers) to thereby secure the hood on the user, as shown in FIG. 2. This feature is designed particularly for windy conditions, where a light-weight disposable rain hood 1 could be blown off of a user 100 by a gust of wind. Although only one pair of holes 50 is shown in the drawings, additional holes 50 can be provided along the open edge 40 to thereby accommodate different sizes and preferences of users 100.
C. Stacked Assembly of Disposable Biohazard Containment Bags Having a Reinforced Holder
Another type of item that can be used with the reinforced holder 701 is the disposable biohazard containment bag 106 shown in FIGS. 15A and 15B. The preferred structure of biohazard containment bags 1106 is well known and is not unique to this invention. However, the reinforced holder 701 provides an effective and heretofore untried method of displaying and dispensing biohazard containment bags 1106.
In FIG. 15A, the items 106 suspended form the reinforced holder 701 are disposable biohazard container bags 1106. The biohazard containment bags 1106 are shown stacked together in a set 101. As shown most clearly in FIG. 15B, each biohazard containment bag 106 comprises a generally elongated bag. Each bag preferably has two separate compartments, a from storage compartment 1109 and a rear storage compartment 1119. The front storage compartment 1109 is formed from a front sheet 1110F and a middle sheet 1110M. The rear front storage compartment 1119 is formed from a middle sheet 1110M and a rear sheet 1110R. The front storage compartment 1109 is designed to hold hazardous materials, and therefore has a re-sealable locking means 1105 for use in selectively sealing an opening 1107A. The re-sealable locking means 1105 is preferably a lengthwise clasp of the type sold on plastic bags under the trademark ZIPLOC. A permanently closed end 1107B prevents biohazard material from escaping from the bag 1106. As shown in FIG. 15A, a biohazard safety symbol is preferably imprinted on an out surface of front sheet 1110F. The rear storage compartment 1119 is designed to hold materials that do not pose a hazard. The rear storage compartment 1119 has a rear opening 1117A, which is simply a slot formed below the upper end of the rear sheet 1110R of the bag, as shown most clearly in FIG. 15B.
As shown in FIG. 15A, each biohazard containment bag 106 is preferably attached to the display holder 90 via a suspension portion 80. The suspension portion 80 is detachably connected to the upper end of the bag 106 by a frangible perforation 108, such that a selected disposable receptacle 106 may be selectively detached from the suspension portion 80 and the display holder 90 by pulling the disposable receptacle 106 relative to the display holder to thereby break the frangible perforation 108.
D. Stands for Display of Stacked Assemblies
FIGS. 3 and 4 show a preferred embodiment of the disposable rain hood 1 displayed on a display stand 200. Such stands are distributed by Custom Specialties & Supply, Inc. Of Metairie, La. As shown in FIGS. 3 and 4, such display stands 200 comprise a base 202 for supporting the stand, a pole 210 extending substantially vertically upward from the base 202, and a pair of display prongs 216 positioned adjacent an upper end 212 of the pole 210 and held in place with a second, thinner pole 214 perpendicular to said prongs 216. The display stand 200 is also preferably provided with a sign holder 220 on the upper end 212 of the pole 210. In the embodiment shown most clearly in FIG. 4, the sign holder 220 consists of a pair of parallel plates 220 having an inwardly turned lower edge 222 and inwardly turned side edges 224, the inwardly turned edges providing a means for holding a sign insert. The sign insert can contain writing informing passers-by about the disposable rain hoods 1, 106 and/or can be provided with advertising information.
Although numerous designs and configurations can be used for the display stand 200, FIG. 5 shows a design for a base 202 for the display stand 200 that has been useful for displaying disposable rain protection devices 1, 106. The base 202 shown in FIG. 5 has a generally cylindrical opening 240 that extends substantially vertically into the base 202. Any of a number of configurations could be used for the base 202, provided that the base is light in weight (light weight being preferable to facilitate movement, repositioning, shipping and storage of the display stand 200) and is capable of maintaining the cylindrical opening 240, insert 310, and pole 210 in a substantially vertical orientation. The configuration of the base 202 shown in FIGS. 3 and 5 is a modified flattened cone which is circular when viewed from above. This configuration provides a solid base, minimizes the volume required for the base, and is esthetically pleasing. In the embodiment of the base 202 shown in FIG. 5, the vertical generally cylindrical wall 243 of the opening 240 is contiguous with the base 202. In this embodiment, the upper end 246 of the opening 240 forms a support for the insert 310 on the outer surface 234 of the base 202, as will be described in further detail below. Other support means could be provided, however, such as sizing the insert 310 and opening 240 such that the lower end 312 of the insert 310 rests on a closed bottom end 242 of opening 240. In order to minimize the weight of the base 202, the base 202 shown in FIG. 5 has a substantially hollow interior 235. In order to provide additional support to the base 202, particularly in view of the minimization of weight and materials used in forming the base, it is preferable to provide the interior 235 of the base 202 with a plurality of support ribs 245. The support ribs 245 preferably extend radially outward from the base opening 240. In a preferred embodiment, the support ribs 245 are contiguous with the exterior surface 244 of the opening 240. Additionally, in a preferred embodiment, upper edges of the support ribs 245 are contiguous with an interior surface 232 of the base 202. The insert 310 is positioned in the generally cylindrical opening 240 of the base 202. The insert 310 is preferably detachably engaged within the cylindrical opening 240 of the base, but it can alternatively be fixedly attached to the opening 240. As shown in FIG. 5, the insert 310 comprises a generally cylindrical body 316. The body 316 has a generally cylindrical opening 328 passing longitudinally through at least an upper end 314 thereof. In the embodiment shown in FIG. 5, the generally cylindrical opening 328 passes entirely through the body 316. As shown in FIG. 5, a plurality of longitudinal ribs 317 extend radially outward from the body 316. As shown in FIG. 4, the outer longitudinal edges 318 of the ribs 317 are sized to tightly abut against the interior wall 243 of the generally cylindrical opening 240 of the base 202, to thereby maintain the insert 310 in a substantially vertical orientation relative to the base 202. In the preferred embodiment shown in FIG. 5, a portion 319 of each of the ribs 317 of the insert 310 taper toward a lower end 312 of each of the ribs 317. The tapered end 319 of the insert 310 facilitates insertion of the insert 310 into the opening 240 in the base 202. An end plate 320 is preferably formed on an upper end 314 of the insert 310. The end plate 320 preferably has a diameter greater than the opening 240 in the base 202 to thereby support the insert 310 on the base 202. A lower surface 322 of the end plate 320 is preferably contiguous with upper ends of the ribs 317. As shown most clearly in FIG. 5, an outer portion 326 of the end plate 320 extends beyond the edges 318 of the ribs 317, providing a support 326 for supporting the insert 310 on the upper end 246 of the opening 240 of the base 202. The pole 210 is sized to tightly fit within the opening of the insert 310. A lower end 218 of the pole 210 is positioned in the opening 328 in the upper portion 312 of the insert 310. With the insert 310 positioned in the opening 240 of the base 202, the pole 210 extends substantially vertically upward from the base 202.

FIGS. 9-12 show a wall mounted display stand. The wall mounted stand of FIGS. 9 and 10 can be used with the reinforced display holder of the present invention, and is fully interchangeable with the preferred embodiment of a display stand shown in FIGS. 3-5. As shown in FIG. 9, the wall mounted apparatus for displaying and dispensing disposable rain protection devices of the invention comprises, generally, a bracket member 400 and a means, e.g. 420, 422 for mounting the bracket member on a wall. The bracket member 400 is configured to hold disposable rain protection devices 1, 106 (see FIGS. 2-4) when the bracket member 400 is mounted on a wall 300. The basic concept of the invention is to provide a stand for displaying and dispensing disposable rain protection devices that can be mounted on existing structures in a building or the like, thereby eliminating the need to provide a structure, such as a base and vertical pole, for displaying such items. As such, the term “wall” as used herein means conventional walls of buildings, including both inside and outside walls. Additionally, the term “wall” as used herein also includes other generally fixed structures of buildings, such as vertical or horizontal beams, walls of counters, shelves, doors, and the like.
As shown in FIGS. 9-12, the apparatus is preferably provided with a sign holder 420. In a preferred embodiment, the sign holder 420 comprises a plate and a plurality of frame members 430A, 430B, 432. The frame members 430A, 430B, 432 are positioned substantially along opposing side edges and a lower edge of the plate, and are configured to retain a sign in the sign holder 420. In the preferred embodiment shown in FIGS. 1-4, the sign holder 420 consists of a substantially rectangular plate 420. Three side edges 430A, 430B, 432 of the plate 420 are turned inward toward a front surface of the plate. The inwardly turned sides 430A, 430B, 432 define grooves for receiving and retaining a sign in the sign holder 420. A sign 450 can be removably mounted in the sign holder 420 by sliding the sign 450 into the grooves 430A, 430B, 432. The sign 450 may provide writing, logos, or other indicia 460 related to advertising or providing information, including advertising or information about the items 1, 106 suspended on the reinforced holder 701.
As shown most clearly in FIG. 11, the bracket member 400 preferably comprises at least one hook 401. In the embodiment shown in FIG. 11, a support portion 404 of the hook 401 extends from the sign holder 420. The support portion 404 preferably extends downward or sideward from the sign holder 420, such that items suspended from the hook 401 will not obscure the surface of the sign holder 420 or sign 450. A suspension portion 406 of the hook 401 is positioned to extend outward from the wall 300 and the sign holder 420 when the device is mounted on the wall 300, to thereby permit the suspension portion 406 to hold the disposable rain protection devices 1, 106 for display and dispensing. In the preferred embodiment shown most clearly in FIG. 11, the hook 401 is configured as a substantially vertical downwardly depending support portion 404, a suspension portion 406 extending substantially perpendicularly from a lower end of the support portion 404, and the suspension portion 406 having an upwardly turned prong 408 for securing disposable rain protection devices 1, 106 on the hook 401.
In the preferred embodiment shown in FIGS. 9-12, the bracket member 400 has two of the hooks 401. The bracket member also preferably further comprises an elongated bar 402. The elongated bat 402 is preferably fixedly positioned substantially along a lower edge 432 of the sign holder 420. An upper end of the support portion 404 of each hook 401 is preferably fixedly positioned on either end of the elongated bat 402. This particular embodiment can be formed from a single piece of heavy steel wire (e.g., 0.5 cm diameter wire).
In a preferred embodiment shown most clearly in FIGS. 2-3, each hook 401 is preferably further braced relative to the sign holder 420 by a brace member 440. In a preferred embodiment, the brace member 440 extends downward from the sign holder 420 along the support portion 404 of the hook 401, and the support portion 404 of the hook 401 is fixedly connected to the brace member 440, such as by welding. The brace member 440 may be a small sheet of metal welded to the back of the sign holder, as shown most clearly in FIG. 11.
Various means can be used for mounting the wall mounted display stand 400 on a wall 300. FIG. 9 shows a plurality of holes 422 through the sign holder 420. FIG. 12 shows a screw, bolt, nail, or the like 500 inserted through a hole 422 and into the wall 300 to thereby secure the apparatus 1 on the wall 300. FIG. 11 shows the use of adhesive tape 510, the tape 510 preferably having adhesive 512A, 512B on either side, as a mounting means. Alternatively, hooks could be provided on the wall 300 for latching onto hooks, eyelets, or a picture wire positioned on the back of the sign holder 420, in the conventional manner of hanging pictures or other wall mounted items.
The various components of the wall mounted sign can be constructed of conventional rigid and generally durable materials, such as metal, plastic, or wood. Steel provides a durable bracket and sign holder that can be economically manufactured using conventional bending, shaping, and welding techniques.
In operation, the items 1, 106 are displayed and dispensed from a display stand 200 or wall mounted display stand 400 via the reinforced aperture 604, such that the plurality of items 1, 106 depends downward from the reinforced display holder 701. When suspended in this manner, an individual item 1, 106 may be selectively removed from the display holder 200, 400 by pulling the individual item 1, 106 downward relative to the bracket 216, 400 to thereby break the frangible connection without tearing the reinforced aperture 604.
The suspension portion 80 can be formed below the lower edge 20 by punching a frangible perforation 22 substantially along and adjacent the lower edge 20 of the flaps 2A, 2B, thereby leaving a desired length for the suspension portion 80.
Preparation of a stack 4 of items, such as a stack of disposable rain hoods 1, is accomplished by first constructing a plurality of the items 1, 106. The plurality of items 1, 106 are then stacked together such that the suspension portions 80 are stacked atop one another and such that the upper edges 10 are stacked atop one another, as shown in FIGS. 3 and 4. A reinforced display holder 700 is then stapled or otherwise attached to the suspension portions 80, such that the plurality of disposable rain hoods 1 are held together at the suspension portions 80, such that the stack 4 may be suspended from a display stand 200 by the aperture 604 on the display holder 90, and such that a selected item 1, 106 may be selectively detached from the suspension portion 80 by pulling the selected item 1, 106 relative to the display holder 90 to thereby break the frangible perforation 22.
Although the present invention has been described in terms of specific embodiments, it is anticipated that alterations and modifications thereof will no doubt become apparent to those skilled in the art. It is therefore intended that the following claims be interpreted as covering all alterations and modifications that fall within the true spirit and scope of the invention.
