A plurality of cavities are formed in at least a first layer, each cavity shaped to conform to and retain therewithin the light bulb or other maintenance article.
The present application claims priority to the Provisional U.S. Patent Application Ser. No. 60/683,762 filed May 23, 2005 by the same inventors and entitled STORAGE DEVICE FOR LIGHT BULBS.
BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention generally relates to packaging devices and, more particularly, to protective devices for storing glass or other fragile items such as light bulbs. The device may also be configured for storing other supply articles used in the routine maintenance of residential or office habitation.
2. Description of the Prior Art
Packaging devices are readily available for storing nearly all kinds of glassware and other fragile glassware items. Some examples of the types of items stored in protective packaging devices include glassware, dishware, crystal ware, vases, art glass, ornaments, figurines, and the like. Such packaging is especially required for storing or shipment of fine or heirloom quality items that must be protected from the shock of handling.
One type of product that is typically provided with only minimal protective packaging for storage is the ubiquitous light bulb. The packaging typically consists of paper or low-strength cardboard fitments designed to support the bulb within some sort of carton. Often, the carton itself is die cut with folded, upset portions or panels that support and enclose the bulb while separating one bulb's surfaces from an adjacent bulb's surface in packs of more than one bulb. This type of packaging is light weight and inexpensive to produce, and also facilitates handling the bulbs during packing for shipment or for display in a retail environment. However, this type of packaging is structurally weak, providing little or no protection against mechanical shock or impact and against being tightly packed with or under other articles. Moreover, this type of packaging has several other disadvantages from the point of view of the end user, particularly as to its utility in fulfilling the functions of storage, selection, and inventory status.
For example, end users (“users”) in residential or office habitations often keep a supply of light bulbs on hand, usually storing them in some out of the way location on a shelf or in a box or cabinet. The packaged bulbs are placed in a container or stacked on a shelf, often in a haphazard manner because, once a particular bulb is sought, sorting through the available bulbs leaves the unselected bulbs in disarray. This impairs subsequent searches for the correct bulb (unless all of the bulbs are of the same type and rating), because the user must typically handle each bulb to locate its rating or type. Moreover, this method of storing the bulbs impairs taking an inventory of the bulbs on hand when a shopping list is being prepared, because, again, each individual bulb or bulb package must be handled to ascertain its type and rating. With this type of bulb packaging and storage, it is almost impossible to perform a selection of a bulb for replacement or to determine the inventory status by inspection without handling each bulb individually. Handling each bulb individually is time consuming, tends to disturb the inventory arrangement, and risks damage to the bulbs. Further, once a bulb is selected, the paper packaging typically available in the prior art, having no useful shape without a bulb inside, has little or no utility and is usually discarded along with the burned out bulb that the contents of the packaging replaced.
What is needed is a storage device for light bulbs that overcomes these deficiencies and provides added utility and protection for the bulbs.
SUMMARY OF THE INVENTIONAccordingly, an apparatus is provided for storing light bulbs, comprising a unitary block or layer of resilient, low density material and having at least first and second substantially parallel sides spaced a predetermined distance apart; a plurality of cavities formed in the block, each cavity having an outline shape corresponding to a silhouette of a light bulb to be stored therein, at least a single opening to the first side of the block, and spaced from adjacent cavities according to a cross section dimension of the light bulbs to be stored therein; wherein at least a portion of each cavity has a reduced cross section dimension to enable the portion of the cavity to exert a retaining pressure upon the bulb stored therein.
In another aspect, an apparatus for storing maintenance articles for office and residence habitations is provided comprising: a first unitary layer of a resilient, low density material having first and second substantially parallel sides spaced a first predetermined distance apart; at least a first cavity formed in the first layer, the first cavity having an outline shape corresponding to a silhouette of a first maintenance article to be stored therein, at least a single opening to the first side of the block, and spaced from an adjacent cavity by a second predetermined distance; at least a second cavity formed in the first layer, the second cavity having an outline shape corresponding to a silhouette of a second maintenance article to be stored therein, at least a single opening to the first side of the first layer, and spaced from an adjacent cavity according to the second predetermined distance; a second unitary layer of substantially rigid, low density material having first and second sides, wherein the first side of the second layer is attached to the second side of the first layer; and at least one cavity formed in the second layer is aligned with and forms a portion of a corresponding cavity in the first layer when the second layer is attached to the second side of the first layer; wherein at least a portion of each cavity in the first layer has a reduced cross section dimension to enable the portion of each cavity so reduced to exert a retaining pressure upon the article stored therein.
BRIEF DESCRIPTION OF THE DRAWINGS
Referring to
The resilient material, which is preferably homogeneous, may be selected from several available synthetic foam materials such as polyurethane (PU), and preferably has a density of 0.8 to 1.5 pcf. Polyurethane is available in a wide variety of densities and firmness, as well as having other useful properties, including some resistance to slipping of smooth surfaces in contact with it such as the surface of a light bulb. The latter property facilitates gently retaining a bulb in a cavity while protecting it from impact or a moderate amount of pressure. Further, the resilient foam material may be provided in any suitable color.
There are three rows of cylindrically shaped cavities in the block 12 of foam material of the embodiment of the storage device 10 illustrated in

Referring to
The cavities formed in the first layer 62 include a cavity 66 for storing a standard flood lamp bulb (not shown), and a cavity 68 for standard sized light bulbs, of which four are provided in the embodiment shown. The cavity 68 includes finger spaces 70 located on opposite sides of the cavity 68 to enable a user's fingers to grasp the sides of the light bulb stored in the cavity 68. The finger spaces 70 may be formed part way into the foam material from the top surface shown in the figure. Other cavities are provided for articles often needed for routine maintenance of a dwelling or habitation. A cavity 72 (without finger spaces) is provided for storing one or more jars of paint (not shown in
While the invention has been shown in only one of its forms, it is not thus limited but is susceptible to various changes and modifications without departing from the spirit thereof. For example, other types of homogeneous materials may be used to fabricate the homogeneous, resilient block, as long as the same density and resilient properties are utilized. Combinations of foam materials, both resilient and rigid may be used to advantage in configuring a storage device for light bulbs and associated supply articles used in a typical habitation. For example, builders of new homes or apartments, landlords, housing authorities, mortgage lenders, or other interested parties may provide storage kits—e.g., “Spiff Kits”—constructed according to the invention and stocked with assortments of light bulbs and or other articles for use by the new owner or occupant in maintaining their habitation. Moreover, the storage device may be configured and used advantageously for the protective storage of any kind of glass item such as fine china, heirloom quality art glass, vases, crystal, pottery, ornaments, and the like. When configured for other than light bulbs, the density of the resilient material should be adjusted to suit the type of item to be stored.
