Abstract
Double-walled decorative articles such as flower vases and candle holders comprise an inner form defining a receptacle and an outer form, spaced apart from the inner form, to create a cavity. A bottom opening in the outer form enables decorative filler materials to be introduced to the cavity such that the decorative materials do not enter into the receptacle, which may contains flowers, water, candles, hot wax or other substances. A removably replaceable plug or cap is used to close off the bottom opening following the introduction of the decorative filler materials. The inner and outer forms may be provided as a unitary item or separate pieces may be joined. The decorative filler materials may be provided in conjunction with the article as part of a kit, in which case the amount of filler material is matched to the volume of the cavity.

DETAILED DESCRIPTION OF THE INVENTION
[0056] This invention resides in double-walled articles and methods of making the same. The preferred embodiments include different shapes and sizes of flower vases and candle holders. FIG. 1 is a drawing of an embodiment of the invention. All embodiments include an aperture formed on a lower surface for gaining access to the space between the double walls. This enables the articles according to this invention to be filled with decorative filler materials that do not interfere with the candle or plant holding receptacles which may contain hot wax or water. In all embodiments a cap may be provided to seal off the aperture once the decorative filler materials have been introduced.
[0057] FIG. 1 illustrates a preferred embodiment of the invention. The article, preferably of glass, includes an inner wall 102, and an outer wall 104 creating a volume that may be filled with decorative materials 202 as shown in FIG. 2. Generally the article is turned upside, down as shown in FIGS. 15A-15F, or on its side to feed the filler materials into the volume 106. Such materials may include glass gems, glass pebbles, sea glass, decorative sands, decorative stones and pebbles, plastic gems and icons, wood, liquid and any other alternatives as long as the materials can be loaded through removable/replaceable plug 110. Inner wall 102 creates a vase 108 that may be filled with water, flowers, etc. Due to the way in which the article is constructed, the decorative accents do not contact with the contents of the vase 108.
[0058] Articles according to the invention may be constructed entirely from pressed or blown glass, though such techniques may be expensive. As such, a two-piece construction may be used as shown in FIG. 3. This process involves an outer form 302 connected to an inner form 304. An advantage of this approach is that the inner and outer forms may be made of different colors of glass, or even different materials. For example, the outer form may be made of clear glass and the inner shape may be colored glass. Alternatively, the inner shape may be made of plastic or metal, with the outer shape being made of glass or plastic.
[0059] In FIG. 3, outer form 302 includes an upper edge 303 that is joined to an edge 305 of inner form 304. Inner form 304 may include a formed lip 405 enabling filler material to occupy volume 106 further up the completed article. FIG. 4 shows the edge 402 associated with joining the inner and outer forms 304, 302. If both forms are of glass such as borosilicate glass, interface 402 may be formed and closed with a torch. If different glasses or other materials are used, interface 402 may be made with a suitable bonding agent, including ultraviolet-cured adhesives.
[0060] While FIGS. 1-4 show conical inner and outer forms, different shapes may be mixed and matched. FIG. 5 shows various cross sections applicable to either the inner or the outer forms. FIG. 6 shows side views that may be used for either form. FIG. 7 shows, for example, a square outer shape with a cylindrical inner shape. A myriad other combinations are possible. FIG. 8, for example, illustrates outer shapes directed to holidays, and the like. In each case, a simpler inner form such as a cylindrical cup is used to hold flowers, candles, etc. Although not apparent in FIG. 8 the bottom of each form further includes a port and cap to receive and retain filler material(s).
[0061] FIG. 9 illustrates options that may be desirable is some instances. For example, areas 902, 904 may be strengthened or fortified against filler materials striking these areas during filling. Further, a central portion of the bottom 906 may be recessed so that plug, typically made of plastic or rubber, does not extend outwardly from the bottom, which may lead to instability. A double-walled vase and filler material may be provided in a kit form, in which case the volume of the cavity between the inner and out walls may be measured (with water, for example), enabling a precise amount of filler material to be provided in the kit to fill the cavity to a desired level, including full, ⅔ full, half full, and so forth.
[0062] FIG. 10A is a cross section of a votive candle vase constructed in accordance with the invention including a set of preferred dimensions. FIG. 10B is an oblique view of the votive candle vase of FIG. 10A; FIG. 10C is a side view, FIG. 10D is a top view, and FIG. 10E is a bottom view.
[0063] FIG. 11A is a cross section of a tea light vase constructed in accordance with the invention including a set of preferred dimensions. FIG. 11B is an oblique view of the tea light vase of FIG. 11A; FIG. 11C is a side view, FIG. 11D is a top view, and FIG. 11E is a bottom view.
[0064] FIG. 12A is a cross section of a standard pillar vase constructed in accordance with the invention including a set of preferred dimensions. FIG. 12B is a cross section of a tall pillar vase constructed in accordance with the invention including a set of preferred dimensions. FIG. 12C is an oblique view of a pillar vase; FIG. 12D is a side view, FIG. 12E is a top view, and FIG. 12F is a bottom view.
[0065] FIG. 13A is a cross section of a large tapered floral vase constructed in accordance with the invention including a set of preferred dimensions. FIG. 13B is a cross section of a standard tapered floral vase constructed in accordance with the invention including a set of preferred dimensions. FIG. 13C is an oblique view of a tapered floral vase, FIG. 13D is a side view, FIG. 13E is a top view, and FIG. 13F is a bottom view.
[0066] FIG. 14A is a cross section of a floral bud vase constructed in accordance with the invention including a set of preferred dimensions. FIG. 14B is an oblique view of the floral bud vase of FIG. 14A; FIG. 14C is a side view, FIG. 14D is a top view, and FIG. 14E is a bottom view.
[0067] FIGS. 15A-15F show the way in which an article according to the invention may be turned upside down to receive filler material(s). FIG. 15A shows the article being turned upside down. FIG. 15B shows the plug or stopper being removed. FIG. 15C illustrates decorative accents being added to the volume between the inner and outer forms. FIG. 15D shows the plug being re-inserted. The article is turned over at FIG. 15E, and water (or candles or other substances) are added at FIG. 15F.
[0068] Given that embodiments of this invention are constructed from glass, and that the articles are configured to receive decorative filler materials as described above, the dimensions associated with the bottom filler hole are important. FIG. 16 is a drawing used to illustrate these dimensions. Specifically, X1 is defined as the Strike Point Distance Limit; X2 is the Base Opening Diameter Limit; and X3 is the Base Opening Thickness Limit.
[0069] As shown in FIG. 16, X1 is the distance between the “Strike Point” (the bottommost point on the surface of the outer wall of the inner vessel) and the inner surface of the outer form surrounding the opening or hole in the base or bottom of the vessel. X2 is the diameter (or minimum dimension) of the opening or hole itself. Given that articles anticipated by the invention may be filled with solid objects, a minimum value of X1 and X2 is necessary for a reasonable amount of different kinds and sizes of solid objects to be introduced into the interior cavity of the vessel. While larger distances may be desirable for larger filler materials such as rocks, shells, and the like, a preferred minimum dimension for X1 and X2 is in the range of 0.25-0.5 inches to accommodate the practical use of the decorative products described herein. Note that while X1 and X2 may be the same, they need not be.
[0070] X3 is the thickness of the outer form or vessel in the immediate vicinity where the opening is cut, cored or otherwise formed. The minimum thickness of X3 is in the range of 0.12-0.25 inches. This minimum dimension is important to the ergonomics of the invention; in particular, that the interior cavity is readily accessible via a re-sealable cap to be easy or efficiently to opened/closed by hand and functionally work. A certain amount of space or thickness is necessary for fingers to be able to grab onto an opening mechanism, and it has been discovered that X3 in the range of 0.12-0.25 inches is fundamental for the practical use of the decorative product described herein.
[0071] Whereas embodiments thus described include a removable/replaceable plug enabling the bottom of the vessel itself to rest on a support surface, in alternative embodiments the removable/replaceable plug may cover more of the bottom of the vessel and act as a base for the vessel. As an example, FIG. 17 is a side view of an alternative embodiment of the invention wherein a removably replaceable plug 1704 also function as a base for vessel 1702, which may or may not be double-walled as shown.
[0072] FIG. 18 is a view in partial cross section that illustrates how a vessel fits into the base of FIG. 17. The vessel 1702 has a bottom opening defined by a rim with an inner concave wall surface 1806, an outer convex wall surface 1804, and a bottom wall surface 1808 that may be flat as shown. The wall surfaces 1804, 1806 may be oriented vertically and parallel to one another. In preferred embodiments the rim and receiving groove in the base 1704 are circular though oval and other shapes are possible particularly with rounded corners.
[0073] The base 1704 has a continuous groove 1810 defining an inner concave sidewall 1814, an outer convex sidewall 1812, and a bottom surface 1818. One or more ribs or corrugations 1816 extend from one or both of the sidewalls 1814, 1812, such that when the rim of the vessel is received by the groove a liquid-tight seal is achieved. FIG. 18 shows three ribs or corrugations extending from the inner sidewall, extending radially outwardly into the groove 1810, with the understanding that more or fewer such ribs or corrugations 1816 may extend from either or both of the sidewalls. FIG. 22 shows ribs from the outer sidewall 1812, and FIG. 23 illustrates ribs extending outwardly from both sidewalls.
[0074] The invention is not limited in terms of exact dimensions. However, in preferred embodiments the height of the base may be in the range of 1 to 2 inches, with a radius in the range of 2 to 6 inches or more. The rim of the vessel may have a thickness “z” on the order of 0.25 to 0.75 inches, more preferably about 0.5+/−0.125″. The width of the groove including the ribs or corrugations is slightly less than the thickness of the rim to ensure that the ribs distal edge of the rib(s) deform against a wall surface of the rim to provide a water-tight seal. FIG. 21 shows three ribs 1816′ pressing against the inner concave wall surface of the vessel rim.
[0075] In the preferred embodiment, the base is molded from a single piece or compressible/resilient material such as silicone. The upper surface of the base may include a concave depression 1826 largely for decorative purposes, whereas the bottom surface may also include a depression 1822 to that the base rests on a more stable edge 1820 which may be circular. When seated in the base, surfaces 1828 and 1830 may abut one another for a smooth transition between the vessel and the base.
