This technology generally relates to glass bottles and, more particularly, to glass bottles (e.g., wine bottles) having a body portion that is essentially cylindrical in shape, and to methods of making and modifying the architecture of such bottles to produce a rotationally stabilized bottle that resists accidental rolling and resulting breakage, in which rotational set points control bottle rotation, aid in the stacking of bottles, removal of lees and sediment from bottles, and also aid in keeping identifying labels visible on the upper surface of horizontally displayed bottles.
Conventional glass wine bottles used for packaging and selling wines include but are not limited to Bordeaux and Burgundy style bottles having body portions that are essentially cylindrical (e.g., round) in cross-section. For various reasons including maintaining desirable moisture levels in cork wine bottle closures as well as allowing space-efficient storage of wine bottles, such bottles are often stored on their sides. Unfortunately, unless confined by physical barriers, horizontally stored bottles are susceptible to accidentally rolling from a shelf and shattering on a hard floor. Additionally, the ease with which horizontal wine bottles can roll makes it challenging to store multiple layers of stacked bottles unless the stacks are placed in a walled or otherwise confined space. Furthermore, when a bottle is stored on its side at home or on a store shelf, the easy rotation of such bottles makes it difficult to keep a wine-identifying label facing upward and visible.
Additionally, certain varieties of wines such as Champagnes require riddling or “remuage” (French), i.e., the removal of lees or sediment after bottling. The process involves turning a tilted bottle in which the bottle's body is rotated in small increments (e.g., ¼ to ⅛ of a turn every day or two) allowing gravity to draw sediment into the neck of the bottle for removal (disgorgement). Tracking these incremental rotations can be challenging.
Exemplary devices are found in the prior art that prevent a round bottle from rolling. These include a variety of bottle accessories that physically secure round bottles such as bottle-holding bags and frictionally mounted square-shaped sleeves that prevent bottle rotation. Additionally, the shapes of some bottles have been altered to include essentially polygon-shaped cross-sections, e.g., rectangular, square, or hexagonal bottle cross-sections, providing a flat and stable resting surface that prevents bottle rolling. While bottle storage accessories and bottle modifications may be implemented, adding devices to bottles may be inconvenient and cumbersome when storing many bottles of wine. The more radical strategy of altering a wine bottle's essential geometry, i.e., from the cylindrical cross-section to a square or polygon cross-section, may introduce unanticipated problems and costs. These include but are not limited to the large cost of molding and handling newly shaped glass bottles while increasing the amount of glass required for molding bottles that have a strength and impact resistance comparable to a cylindrical-shaped bottle that holds the same volume of liquid. In recent years there have been a few examples of wines being packaged and sold in bottles with square cross-sections. The French wine producer Château de Berne has been packaging wine in square bottles for over a decade. Matuba Vineyards in South Africa and Truett Hurst Vineyards in California have likewise offered wines in square bottles. It is claimed that these bottles take up less space than round bottles in shipping and storing, and because the bottles do not roll away, they can be more easily stored on their sides. However, the square wine bottle has, to the present time, remained more of a curiosity than a commercial success.
The present invention features a molded glass bottle (e.g., a glass wine bottle) with a generally cylindrical cross-section (e.g., a round shape), size, and interior that appear remarkably similar to a conventional glass bottle. Like conventionally manufactured glass bottles, the present bottles have a neck portion, shoulder portion, substantially cylindrical body portion, heel or base portion and, optionally, a recessed punt portion forming the bottom of the bottle (see
The bumpers can vary in their extent of protrusion (also referred to herein as projection) as measured outward from the outer wall surface of the bottle and/or can vary in their overall size and shape. For example, rounded-top or beveled-top bumpers can project outward about 2 mm-5 mm from the outer sidewall surface of a 750 ml bottle (
The overall shape of the interior and exterior of the bottle's body portion remain essentially cylindrical. However, while the interior surface of the body portion remains round and smooth without any surface discontinuities (e.g., essentially identical to a conventional Bordeaux or Burgundy style glass wine bottle), the exterior surface of the bottle's body portion has been altered. More specifically, the exterior surface can be disrupted by a series of regularly spaced surface discontinuities that are integrally molded in the form of multiple low-profile glass protrusions or bumpers on the outer wall surface of the bottle. For example, the molded protrusions may be, for example, between 8 and 20 low profile bumpers, preferably 8 or 9 low profile bumpers that are regularly spaced around one circumferential path around the body portion of the bottle, or alternatively between 16 and 18 low profile bumpers regularly spaced around two parallel circumferences or circumferential paths around the body portion of the bottle. The bumpers are provided in the form of a geometric shape such as round buttons or alternatively, narrow strips of various lengths essentially parallel to the central axis of the bottle. Each protrusion (termed “bumper” herein, regardless of the shape or dimension) projects outward from the outer sidewall surface of the bottle between approximately 2 mm to 6 mm, e.g., between approximately 2 mm and 4 mm (preferably about 2.5 mm to about 3 mm) for a 750 ml bottle and about 3 mm to about 6 mm for a 1.5 L bottle (preferably between about 4 and about 5 mm) and between approximately 2 and 10mm wide. For example, when the body portion of a 750-1000 ml capacity wine bottle having a diameter of between approximately 3 and 3.5 inches is viewed in cross-section and the bumpers are viewed in pairs around the circumference of the bottle, the bumpers are of sufficient height so that a tangent line drawn between the highest or tallest points on neighboring bumpers does not intersect the surface of the bottle between neighboring bumpers (see black protrusions in
As described above, the bumpers can be formed in many different geometric shapes, e.g., as small round button-shaped bumpers or even narrow strips (continuous or interrupted strips) oriented parallel to the central axis of the bottle. The bumpers can be generally formed during bottle molding from either a molten glass or from a thermoplastic resin at the same time as the entirety of the bottle is molded. In a preferred embodiment, the bumpers comprise glass or a thermoplastic resin. The bumpers can be positioned on the outer sidewall surface of the bottle's substantially cylindrical body portion. The bumpers can be positioned and spaced apart at regular intervals, e.g., at approximately 0.9-1.5 inch intervals around a 750-1000 ml wine bottle's circumference, preferably spaced at between 1.0 and/or 1.3 inch intervals (center to center distance between bumpers). The circumference of a 750 ml capacity glass wine bottle measures approximately 9.0-9.5 inches. The bumpers can be positioned and spaced apart at regular intervals, e.g., at approximately 1.2-1.8 inch intervals around a 1.5 L wine bottle's circumference, preferably spaced at between 1.3 to 1.6 inch intervals (center to center distance between bumpers). The circumference of a 1.5 L capacity glass wine bottle measures approximately 13.0 inches, with a typical diameter of approximately 4.1-4.2 inches. As described above, the bumpers or protrusions may be formed as short or long strips (e.g., between 1 cm and 15 cm in length) or alternatively formed as round button-shaped elements, all of which have adequate height to stabilize a wine bottle against rocking and/or rolling. These bumpers generally project from the outer sidewall surface of the bottle between 2 mm and 6 mm (preferably between about 2 mm to about 4 mm and more preferably between about 2.5 mm to about 3 mm for a 750 ml bottle, and preferably between about 3 mm to about 6 mm and more preferably between about 4 mm and about 5 mm for a 1.5 L bottle) and generally are between 2 mm and 10 mm wide and are spaced apart at similar intervals, depending on the size of the bottle, around the circumference of the bottle's body portion. The spacing and height of each successive pair of these protrusions around the circumference can allow a conventional 750 ml glass wine bottle (having an outer diameter of approximately 3 inches) or a 1.5 L bottle (having an outer diameter of approximately 4.1-4.2 inches) to be rested and stored on its side, e.g., on a shelf, where the bottle is stabilized against rolling as it stably rests on pairs of the bumpers. By comparison, when a bottle with a cylindrical body portion is stored on its outer sidewall surface, the bottle is often susceptible to rolling and accidental breakage. The presence of the above-described oriented protrusions that serve as stabilizing feet on a bottle's body sidewall can also facilitate bottle stacking by limiting bottle rotation around the central axis of a bottle. By limiting such rotation, the protrusions can also aid in maintaining bottle orientation required for desirable upward display of a wine bottle's label when a bottle is displayed horizontally. Furthermore, the ability to control rotation of a wine bottle between successive pairs of protrusions supporting a wine bottle on its side facilitates manual riddling and removal of the lees or sediment in a wine such as a champagne. More specifically, with the protruding bumpers being spaced apart in discrete intervals around the circumference of the bottle, a controlled step-wise rotation of the bottle in discrete angular increments can be facilitated, e.g., in steps of 30 to 60 degrees, and preferably 40-45 degrees, for a 750-1000 ml bottle or a 1.5 L bottle, over a period of days or weeks, and this feature facilitates removal of lees and sediments from the bottle.
The inventor produced prototype wine bottles in which the outer sidewall circumference of the body of conventional glass wine bottles has been fitted with commercially available small round adhesive bumpers similar in size to the glass or thermoplastic resin protrusions described in the present disclosure. Attachments of these bumpers with center to center spacings of approximately one inch around a 750 ml bottle's circumference are shown in
The spacing of the bumpers around differently sized and/or shaped glass bottles can vary depending on the diameter of the bottle as shown in
The bumpers can comprise glass or a thermoplastic resin. The bumpers can be integrally molded into the outer sidewall surface of the substantially cylindrical body portion of a glass bottle.
In an embodiment, a typical 750 ml capacity Bordeaux or Burgundy style wine bottle having an approximate 3.0-3.25 inch outer diameter (and thus about 9-10 inch circumference), the centers of approximately 8-10 such bumpers should be spaced at equal intervals (approximately 0.9-1.5 inches apart, preferably about 1.0 to 1.3 inches apart) around the circumference of the body portion of the bottle near the shoulder and/or base of the wine bottle.
In another embodiment, a 1.5 L bottle having an outer diameter of approximately 4.15 inches (and approximately 13-inch circumference), the centers of approximately 8-10 such bumpers should be spaced at approximately equal intervals (approximately 1.2 to 1.8 inches apart, preferably about 1.3 to 1.6 inches apart) around the circumference of the body portion of the bottle near the shoulder and/or base of the wine bottle.
In an embodiment, at least two approximately parallel and essentially identical circumferential paths are selected for positioning the bumpers around the bottle's outer sidewall circumference, with one circumferential path located near the base of the bottle and the other circumferential path located near the shoulder of the bottle. Preferably, one circumferential path is located approximately 1 to 2 inches from the base of the bottle, and a second circumferential path is located approximately 1 to 2 inches from the shoulder of the bottle. In other words, the circumferential paths are separated by about 3-7 inches, preferably about 4-6 inches, measured along the central axis of the 750 ml bottle or the 1.5 L bottle. The location of the circumferential paths in these portions of the bottle enables attachment of a label to the center of the bottle without interference from the bumpers. Pairs of the bumpers along these two paths can be aligned with each other parallel to the central axis of the bottle to prevent rocking of the bottle when resting on its side on a flat surface. This separation can provide stabilization against rolling along the length of the bottle.
In an embodiment, the outermost surface of the bumpers upon which the bottle rests can be typically contoured for improved bottle stability against rolling, i.e., bevel-contoured, V-shaped, or otherwise contoured (see body cross-section in
In an embodiment, the bumpers project sufficiently above the surface of the bottle (e.g., 2 mm-4 mm and preferably about 2.5 mm to about 3 mm for a 750 ml bottle, or 3 mm-6 mm and preferably 4 mm-5 mm for a 1.5 L bottle) so that a tangent line (see “T” in
Because a series of bumpers preferably lie in evenly spaced pattern around the circumference of the bottle, the bottle can be stable regardless of the rotational position of the bottle. As described above, it is preferred that at least two matching, i.e., essentially identical, circumferential paths of bumpers are formed around the circumference of the bottle separated by several inches (e.g., 3-7 inches, preferably about 4-6 inches measured along the central axis of the 750 ml bottle or the 1.5 L bottle). If one circumferential path of bumpers is positioned high and one low on the outside wall of the bottle's essentially cylindrical body portion, the bottle is well stabilized against rolling along its full length. In addition to preventing wine bottles from rolling along a storage shelf, the bumpers also help stabilize a stack of bottles against movement after the bottles have been placed horizontally atop one another on a surface. Integral glass or thermoplastic resin bumpers as described herein add negligible weight or cost to a bottle and do not alter the bottle's interior shape nor a bottle's pouring qualities. For example, with typical soda lime glass bottles having a wall thickness of approximately 2.8-3.3 mm, the glass or thermoplastic resin bumpers described herein project about 2 mm to 4 mm, preferably about 2.5 mm to 3 mm from the outer sidewall surface of the bottle for a 750 ml bottle and about 3 mm to 6 mm, preferably about 4 mm to 5 mm, for a 1.5 L bottle. Therefore, each small bumper produces only a very small and localized increase in the bottle's glass wall thickness over a remarkably small area. Glass bottles described herein may be easily manufactured using existing glass bottle molds in which small bumper-shaped depressions can be machined or otherwise formed in the mold's surface forming the exterior wall surface of the glass bottle. See
A mathematical formula may be used for calculating the amount of added glass required to form, for example, 18 glass bumpers being used to stabilize a 750 ml capacity bottle against rolling. The volume of each protruding bumper can be approximated and calculated by the volume of the cap portion of a sphere. In this instance, the volume of each bumper having a height of 0.25 cm and a base radius of about 0.5 cm, is approximately 0.14 cm3 so that 18 such bumpers will have a volume of 2.5 cm3. With soda lime glass having a density of 2.5 g per cm3 the weight of 18 such bumpers will be approximately 6 g. An average 750 ml capacity empty glass wine bottle weighs between 500 and 600 g and the same bottle filled with wine weighs approximately 1300 g. Therefore, a wine bottle's weight will increase by only about 1% when empty or approximately 0.5% when filled with wine by the addition of the stabilizing bumpers. These additions likely will not measurably alter the manufacturing process for a glass bottle nor the cost of shipping empty or filled wine bottles.
With regard to bottle manufacture, the fabrication of a glass bottle containing approximately 1% by weight added glass that is essentially symmetrically distributed among 16-20 small glass bumpers around the circumference of the bottle's body can be accomplished. Addition of small amounts of glass or thermoplastic resin around the bottle can be achieved by removing very small portions of the ferrous alloy-based tool that is usually employed to mold the outer surface of the body portion of the wine bottle. It is believed the minor alteration required in the bottle-forming tool will not appreciably alter the manufacturing process such as the molding temperature or the mold cycling time. Nor should the addition of small bumpers to the exterior surface of the wine bottle alter the process of filling or sealing the bottle with either a cork or a screwcap style of closure. Importantly, the present invention prevents free rolling/rotation of the bottle while also allowing discrete step-wise rotation between successive pairs of the bumpers on the exterior of the bottle. For example, with a bottle having either 8 or 9 bumpers, each successive rotation step will provide 360 degrees÷8 (or ÷9)=45 degrees (or 40 degrees) of rotation. The present invention can be achieved without any alteration of the substantially cylindrical interior body portion of the bottle. Therefore, the volume and mechanics of liquid filling and pouring from the bottle can remain unchanged. Furthermore, it is expected that there is minimal change in the weight of the bottle, its outer diameter, its method of manufacture, its mechanical handling, its cost, or its packaging requirements for shipping.
In modeling wine bottles of the present invention, it is surprising that nine bumpers positioned at equal intervals (about 0.9 to 1.5 inches apart, preferably 1.0 to 1.2 inches apart) around the circumference of a 3 inch diameter wine bottle (750 ml) at approximately 1 to 2 inches from the base and/or shoulder of the bottle can provide excellent mechanical stability against bottle rolling while protruding outward only 2.5 mm to 3 mm from the outer sidewall surface of the wine bottle (approximately 3% of the bottle's diameter). Similarly, nine bumpers positioned at equal intervals (approximately 1.2 to 1.8 inches apart, preferably 1.3 to 1.6 inches apart) around the circumference of a 4.15 inch diameter 1.5 L bottle at approximately 1 to 2 inches from the base and/or shoulder of the bottle also provide excellent mechanical stability against bottle rolling while protruding outward approximately 4 to 5 mm from the surface of the wine bottle (approximately 4% of the bottle's diameter). The term “excellent stability” against bottle rolling refers to the ability of a glass wine bottle having an outer diameter of approximately 3 inches, a capacity of 750 ml and a weight of between 500 and 600 g to resist rolling when placed on a flat surface inclined at an angle of 15 degrees elevation. From another perspective, these 2.5 mm tall bumpers can provide a series of nine “stabilizing platforms” around the circumference of the 750 ml bottle that are each approximately one inch (25 mm) wide or about ten-fold wider than the 2.5 mm projecting height of each bumper. From another perspective, pairs of these 4-5 mm tall bumpers can provide a series of nine “stabilizing platforms” around the circumference of the 1.5 L bottle, in which the platforms are each approximately 1.44 inches (37 mm) wide or about ten-fold wider than the 4-5 mm projecting height of each bumper.
For a variety of reasons including packaging considerations, it is very helpful to avoid significantly increasing the outer diameter of the glass wine bottle. Accordingly, with the presently described example of a 3.0 inch diameter (76 mm) wine bottle having essentially diametrically opposed glass or thermoplastic resin bumpers on the exterior wall of the bottle (each bumper being only 2.5 mm tall), the bottle's maximum diameter measured across opposed bumpers is only 5 mm greater than the original 76 mm diameter. This represents only about a 6.5% very localized increase in the bottle's maximum outer diameter. It is interesting to note that the anti-rolling feature of this invention is built into the wine bottle's architecture whereas most of the prior art devices that prevent bottle rolling are accessory devices that are less convenient and require separate purchasing. Additionally, this invention leaves the essential shape of the original wine bottle intact with addition of only about 1% to the amount of glass used to form the bottle. This invention solves the wine bottle rolling problem and also facilitates stacking of bottles.
Although preferred embodiments of this invention include glass wine bottles, the invention is not so limited. Any glass (or thermoplastic) cylindrical bottle or jar can be modified with bumpers according to the present invention, and their spacing around the outer surface of the bottle can be determined in a similar manner as described herein for the 750 ml and 1.5 L wine bottles. For example, preferably 8 or 9 bumpers can be added in a single circumferential path near the bottom and/or top of a cylindrical glass bottle, or alternatively 16 to 18 bumpers can be added in two circumferential paths near the bottom and top of a cylindrical glass bottle, such that the bumpers are evenly spaced along the outer surface. The composition, shape and dimensions of such bumpers are as described herein.
Non-limiting examples of such glass cylindrical bottles or jars include water bottles, liquor bottles, beer bottles, pickle jars, jam or jelly jars, solvent bottles, and vinegar bottles.
Within the present disclosure and within the claims that establish the novelty of the present invention, the following terms have the following meanings:
The term “cylindrical” as used herein, refers to the shape of the sidewall of the body portion of most glass bottles such as Bordeaux and Burgundy style wine bottles (including 750-1000 ml bottles and 1.5 L bottles. The body portion of these bottles (see
The term “modified” as used herein, refers to bottles with a substantially cylindrical body portion (such as traditional Bordeaux and Burgundy style wine bottles) in which the outer sidewall surface of the body portion has been altered. More specifically, the modification refers to surface protrusions (collectively termed “bumpers”) that are typically 2-5 mm tall and that are carefully positioned and molded into the outer sidewall surface during bottle fabrication from glass, e.g., from soda lime bottle glass, or from a thermoplastic resin. Without these surface modifications, a substantially cylindrical bottle that is stored on its side may roll and accidentally fall and fracture on a hard floor.
The term “circumferential path” as used herein, refers to the positioning of protruding bumpers around the exterior sidewall of a bottle's body portion. This positioning may follow either one circumferential path or two approximately parallel circumferential paths around the bottle's body (an upper path nearer the bottle's shoulder, and/or a lower path nearer the base of the bottle). The path should be located approximately 1 to 2 inches from either the shoulder of the bottle or the base of the bottle. If the bumpers are positioned along two paths, the paths should be separated by several inches, e.g., 3-7 inches (measured along the central axis of a 750 ml bottle or a 1.5 L bottle) for maximum stabilization of the bottle against rolling. The circumferential paths should be approximately 1 to 2 inches from the shoulder of the bottle, and approximately 1-2 inches from the base of the bottle. The paths can be separated by about 3-7 inches, preferably about 4-6 inches, measured along the central axis of the 750 ml bottle or the 1.5 L bottle.
The term “glass” as used herein, refers to a heat-meltable and moldable material useful in the manufacture of glass bottles, and includes thermoplastic resins as well as any traditional silica-based glass such as common soda lime glass used to manufacture most bottles. If a thermoplastic resin is used in place of silica-based glass, the resin may include but is not limited to PET (polyethylene terephthalate), polyethylene, polypropylene and the biopolymer, PLA (polylactide).
The number of bumpers formed on the surface of a bottle may vary considerably. For example, 8-12 bumpers, preferably 8 or 9 bumpers, may be formed around a bottle if the bumpers are limited to one circumferential path around a 750 ml bottle or a 1.5 L bottle. Approximately twice that number, i.e., about 16-24 bumpers, or preferably 16 to 18 bumpers, may be formed around a 750 ml bottle or a 1.5 L bottle if the bumpers are distributed around two separated circumferential paths. When two paths are utilized, pairs of bumpers in the upper and lower paths around the outer sidewall surface of the bottle should align with each other parallel to the central axis of the bottle so the bottle does not rock when placed on a shelf or other flat surface. As discussed elsewhere in the present disclosure, bumpers can typically project between 1 mm and 5 mm, and preferably between 2 mm and 4 mm outward from the outer sidewall surface of a 750 ml wine bottle or between 3 to 6 mm, preferably between 4 to 5 mm outward from the outer sidewall surface of a 1.5 L bottle. Furthermore, the outermost surface of the bumpers upon which the horizontally stored bottle rests, can be formed with a beveled, V-shaped or otherwise contoured surface to maximize contact between the bumpers and the support surface for the bottle such as a shelf.
