SUMMARY OF THE INVENTION

One aspect of the invention relates to a bottle or container having a shape, design or configuration that allows the bottle or container to be efficiently stacked or nestled with an identically shaped bottle rotated 180 degrees.


Advantageously, according to preferred embodiments, the bottle, when packed with an inverted nestled bottle, has a position that is stabilized by the weight and shape of the inverted nestled bottle for safer packaging, transportation and storage. Also advantageously, according to other preferred embodiments, a bundle containing one or two pairs of stacked inverted bottles require significantly less shelf or storage space compared to conventional bottles. This reduces the cost of packaging, shipping and storage. This also provides conveniences to both consumers with limited storage space and retailers with limited shelf space. Preferably, the bottle or container comprises a top, a bottom, three flat sides and a curved side that allows for the effective stacking.


Thus, unique benefit of the nesting concept is that the nesting bottles take up one-third less space on the retailer's shelves than an equal volume of standard water bottles. With retail space at a premium, this space-saving design should have broad appeal to retailers and manufacturers alike. (See comparison in FIGS. 8 and 9 of how much space six 500 ml bottles (3 liters) of water take up in comparison with an equal volume of liquid using the nesting packaging concept according to the present invention).


Another aspect of the invention relates to bundles, cases and packages comprising two or more pairs of the bottles according to the invention configured to reduce the storage space compared to conventional bottles and containers.

The invention product can be a bottle, container, canister, tank, box, carton or other product for containing fluids, gases, or materials. References to “bottle” or “container” herein shall not be limiting.


Accordingly, one aspect of the invention relates to unique bottle or container designs that provide for more efficient packing, storage and transporting, as well as enhanced stability. Specifically, the product is designed to allow for pairs of bottles or containers to be efficiently nestled when packed or stored by allowing one inverted container or bottle to be stacked directed onto another container or bottle to result in a bundle having a cuboid shape with little or no void space between the stacked bottles.


One embodiment of the invention relates to a stackable bottle comprising one curved side and three flat sides. Preferably, the curved side has a curve resulting in the bottle being narrow at the top and wider at the bottom. Preferably, the shape of the bottle allows it be packaged or bundled efficiently with another identical inverted bottle. Preferably, the pair of bottles or containers is similar to two pieces of a puzzle whereby the curved sides match resulting in a cuboid when the pieces are nestled together.


Another embodiment of the invention relates to a stackable, interlocking bottle comprising a top, a bottom, one curved side and three flat sides. Referring to FIG. 1, the invention is preferably configured to be nestled with an upside-down identical bottle.


Preferably, the bottle has a chair-shape, “pregnant-shape” or h-shape cross-sectional shape with a narrow top and wider bottom. The curved side that “interlocks” or “fits” with the inverted bottle when forming a bundle pair is designed or configured to provide greater stability when stacked and more efficient packing and storage.


Another embodiment of the invention relates to a bottle comprising:

    • (a) a top,
    • (b) a flat bottom,
    • (c) three flat sides; and
    • (d) a curved side,


wherein the curved side has a shape forming a widest bottle dimension at the flat bottom in a first direction perpendicular to the curved side and a narrowest bottle dimension at the top in the first direction,

    • and further provided that the shape is configured such that when such bottle is (i) nestled with an identically shaped bottle which is rotated 180 degrees about the first direction of the bottle and (ii) the flat bottom of the bottle aligned with the top of the rotated identically shaped bottle, the resulting nestled bottles comprise less than five volume percent void space between the bottle and the identically shaped bottle, preferably less than 4 volume percent, more preferably less than 3 volume percent, even more preferably less 2 volume percent, even more preferably less 1 volume percent, and most preferred less than 0.5 volume percent.



FIG. 4 depicts a 750 ml bottle 40 according to the invention having a top 41 with cap 42, bottom 43, flat backside 44, two flat sides 45 and curved side 46 and grip indentation 47. FIG. 5 shows a bundle 50 including the bottle 40 of FIG. 4 nestled with identically shaped bottle 51. As can be seen, the gap or void space 52 between bottles 40 and 51 can be minimized by using a curvature on the curved side 46 that allows the bottles to be nestled efficiently.


According to preferred embodiments, the top is flat.


Preferably, the bottle further comprises a removable cap attached to the top.


Preferably, the bottle further comprises a cap with a closure hidden beneath.


Preferably, the bottle further comprises an opening for filling and discharging the bottle.


Preferably, the bottle top comprises a 1-inch diameter opening. Alternative embodiments can include an opening between ⅞ inches and 1⅛ inches or other ranges suitable for use in the invention.


According to preferred embodiments, the closure device is engineered as such so that when the closure cap is affixed (sealed to the bottle) it ends up flush with the flat sides. Preferably, each side surface of the affixed cap is flush with a side of the bottle. Preferably, the cap has a cuboid shape. Preferably, each exterior side of the cap is flat.


According to preferred embodiments, the bottom of the bottle is flat. Alternatively, the bottom is slightly curved. Preferably, the flat bottom comprises a sculpted (preferably finger-friendly) indentation to allow for easy extraction or lifting of the bottle. Preferably, the flat bottom comprises a sculpted, finger-friendly indentation for easy extraction. Preferably, the flat bottom comprises an indentation to allow for easy extraction or lifting.


Preferably, the bottle further comprises a recess in the bottom with a grip or handle adapted to allow the bottle to be easily extracted with thumb and forefinger from a bundle or package when the bottle or container is inverted upside down.


Preferably, the widest bottle dimension of the bottle is between 1 inch and 5 inches and the bottle has a height between 2 inches and 10 inches. According to preferred embodiments, the widest bottle dimension is between 4 and 5 inches and the bottle has a height between 8 and 10 inches. Alternatively, the dimensions of the bottle or container can range depending on the use and application.


Preferably, the three sides of the bottle are flat.


According to other preferred embodiments, the three sides have slightly curved edges.


Preferably, the curved side comprises a concave portion and a convex portion.


Preferably, the curved side comprises a concave portion adjacent the top and a convex portion adjacent the flat bottom.


Another aspect of the invention relates to bundles, cases, packages or boxes containing two or more nestled bottles according to the invention.


According to one embodiment, the nestled bottles from a rectangular or square cuboid. Preferably, the curved side comprises a symmetrically curved edge that divides the cuboid shape into equal shapes.


For example, to assist in demonstrating the benefits and advantages of the invention, for a 3 liter or any other proportional sized template: the flat two-dimensional side (rectangle) measures 4¾″ wide by 8¼″ tall. Beginning approximately 1″ from the top left edge and extending downward is a symmetrical curved line that serves to divide the shape into two halves of equal dimension and proportion. Or, referring to the right bottle 41 in FIG. 4, curve 42 starts approximately 1 inch from top right curving down to terminate 1 inch right 45 from lower left 46.


According to preferred embodiments, the dimensions are 4¾″×4¾″×8¼″ cuboid, which will result in a total volume of 3 liters comprised of 4-750 ml bottles.


According to preferred embodiments, the bottle, when packed with an inverted nestled bottle, has a position that is stabilized by the weight and shape of the inverted nestled bottle. Referring to FIG. 4, for example, the top bottle on the left holds down and secures the bottom bottle on right. The ability to more tightly pack bottles and containers in an interlocking manner according to the invention results in less shifting, misalignment, vibrations and other packaging, storage and transportation issues.


Preferably, when the bottle is packed with other three identical bottles, the bottles can be packaged to form a rectangular cuboid bundle. Preferably, the rectangular cuboid bundle has six flat sides formed by the four nestled bottles.


Preferably, when the bottle is a 750 ml bottle and is used in a 4-bottle bundle comprised of four identical nestled 750 ml bottles, the bundle comprises at least 10 percent less footprint (or shelve space), preferably 15% less, more preferably 20% less, even more preferably 25% less, even more preferably 30% less, and most preferred 33% less than an equal total volume standard bundle of six 500 ml conventional bottles. This ability to package, store and/or transport liquids and other materials with ⅓ less space provides valuable advantages. Shop owner's benefit from being able to display more items with limited shelf space. Shippers can ship more in the same trucks. Homeowners can store greater amounts of products. Manufacturers can package the bottles or containers using less packaging materials. According to preferred embodiments, the invention provides improved storage economies and efficiencies to both consumers and retailers.


Preferably, the bottles individual are unsymmetrical, while the bundle or package created by nestling two bottles is a cuboid shape (a symmetrical six-sided cube), whether the combined bundle is 2 liters, 3 liters, 4 liters or any size. For example, a cuboid measuring 4¾ inches by 4¾ inches×8¼″ inches yields approximately 3 liters. For the purpose of this invention, the term “cuboid” is defined as a solid figure bounded by six faces in which each of the faces is a rectangle or square and each pair of adjacent faces meets in a right angle (e.g., a cube-like structure).


Accordingly, preferably, the bottle has an asymmetric shape about a vertical axis passing centrally through the bottle centrally through the top. Preferably, bottle has an asymmetric shape about a vertical axis passing centrally through the bottom. For example, a typical water bottle has symmetry looking down on the bottle, with the inventive bottle there's asymmetry since one side is a substantially flat back, while the other side is curved. That is, when looking down on a conventional bottle, one sees a circle, while looking down on the bottle of the invention there is a square or rectangle. As another comparison, if one starts at the center of a conventional bottle and looks outwardly one sees the same dimension in each direction, while not so with the bottle of the invention since the view in one direction is towards a curved side, while the other view is towards a substantially flat back.


Preferably, the bottle is configured to stand upright and stable when on a horizontal surface.


Moreover, according to preferred embodiments, the bottle or container has substantially flat sides so when laid on its side, it doesn't roll providing a more stable container.


Preferably, the bottle comprises plastic or glass.


According to preferred embodiments, the bottle is made using compostable materials. Preferably, made using Ingeo (a corn-based plastic that is (ultimately) compostable). Preferably, the entire container is made from a compostable material, more preferably also the cap, even more preferably, also the packaging.


According to preferred embodiments, the top is sealed using a string and sealing wax. Preferably, the string and sealing wax are applied to maintain a substantially flat top. Preferably, the string closure is decorative to appeal to certain target markets.


According to another preferred embodiment, the cap (under which the opening to the bottle is hidden) is a rectangular cuboid shape that allows more leverage when opening the bottle. Conventional small water bottles, because of their small cap size, are often difficult to open.


Another aspect of the invention relates to bundles or packages containing two or more containers according to the invention for more efficient packing, storage and transportation.


One embodiment of the invention relates to a bundle of bottles comprising four bottles, wherein each bottle comprises:

    • (a) a top,
    • (b) a bottom,
    • (c) three flat sides; and
    • (d) a curved side,
    • wherein the curved side has a shape forming a widest bottle dimension in a first direction perpendicular to the curved side at the flat bottom and a narrowest bottle dimension in the first direction at the top, and
    • wherein the bundle of four bottles form a rectangular cuboid and comprises less than one volume percent void space between the bottles.


Preferably, the bundle further provides that when each bottle is nestled with an identically shaped bottle which is rotated 180 degrees about the first direction of the bottle the resulting nestled bottles comprise less than one percent volume void space between the bottle and the identically shaped bottle.


Another embodiment of the invention relates to a bundle of bottles comprising four nestled bottles, wherein two bottles are right-side up and two inverted 180-degrees upside down and wherein the bundle has a rectangular cuboid shape and each bottle has one curved side nestled against the curved side of another bottle.


Preferably, the bundle of bottles comprises less that five percent by volume void space between the bottles, preferably less than 4 volume percent, more preferably less than 3 volume percent, even more preferably less 2 volume percent, even more preferably less 1 volume percent, and most preferred less than 0.5 volume percent.


Preferably, the curved side has a surface that completely contacts the surface of the curved side of the other bottle.


Preferably the bundle further comprises a binding surrounding the bundle to bind the bottles together.


Preferably, the binding is a sheath of plastic shrink-wrap film.



FIG. 6 shows bundle 60 comprising a first pair 61 and second pair 62 of paired inverted containers according to a preferred embodiment of the invention. Referring to FIG. 6, the four bottles are tightly nestled to form an efficient package 63 with reduce void space between the individual containers. According to preferred embodiments, the resultant bundle is cuboid allowing multiple bundles to be easily stacked, packaged and/or transported. The resultant bundle according to the invention provides enhanced stability as a result of the nestled configuration increasing safety and convenience, while reducing the amount (including strength, thickness, weight, size, etc.) of the packaging material used to form the bundle. For example, referring to bundle 60 shown in FIG. 6, a single half box 63 can secure four containers yet have a reduce shelf footprint as a result of the efficient stacking of the containers. Preferably, the footprint of the four-bottle or four-container package is at least 10% less, preferably 15% less, more preferably 25% less, even more preferably 33% less and most preferably at least 50% less compared to containers that are not nestled or stacked according to the invention.


The ‘nesting’ concept is designed to offer liquid products such as water, beverages ketchup, mustard, shampoo and conditioners, olive and cooking oil, motor oil, or any other liquids that could be sold in units of four to increase sales and provide more efficient packing, storage and/or transportation and also increased stability. In addition to liquids, the containers or bottles may contain flowable or pourable products such as rice, spices, grains, beads, shampoo, olive oil, pellets, soil, fuel, gaseous compositions, fertilizer, or any material or product that can be poured or can flow from a container or bottle.



FIG. 7 shows a container 70 according to another embodiment of the invention including cap 71 and bottom indentation 72 with finger grip 73.


Another embodiment relates to a bottle comprising one curved side and three flat sides, wherein the curved side has a shape forming a widest bottle dimension in a first direction perpendicular to the curved side at the flat bottom and a narrowest bottle dimension in the first direction at the top.


Another embodiment relates to a bottle comprising one curved side and three flat sides, wherein the curved side has a shape forming a widest bottle dimension in a first direction perpendicular to the curved side at the flat bottom and a narrowest bottle dimension in the first direction at the top and further provided that when such bottle is (i) nestled with an identically shaped bottle which is rotated 180 degrees about the first direction of the bottle and (ii) the flat bottom of the bottle aligned with the top of the rotated identically shaped bottle, the resulting nestled bottles comprise less than one volume percent void space between the bottle and the identically shaped bottle


Another embodiment relates to a bottle having a shape characterized by dividing a rectangular cuboid into two equal halves with a curved cut resulting in two of the bottles each having a flat top, a flat bottom, three flat sides and an identically shaped curved side.


Another embodiment relates to a bottle comprising one curved side and three flat sides and further provided that the curved side is configured such that when such bottle is (i) nestled with an identical bottle which is rotated 180 degrees about a first direction perpendicular to the curved side and (ii) the nestled bottles are aligned by height top to bottom, the resulting nestled bottles comprise less than one volume percent void space between the bottle and the identically shaped bottle.


According to one preferred embodiment, the design or configuration can be defined by starting with a cuboid measuring 4.5 inches×4.5 inches×8.3 inches. The cuboid may be of different dimensions, depending on the volume of the bottles needed for the final product, but the concept and the shape of the resulting bottles remains the same. This shape represents 3.05 liters in volume. The cuboid is then divided into two equal halves with a curve shaped cut. The remaining side is then divided in half with a straight vertical cut. The result is four equal shapes, each containing approximately 750 ml of volume. A cuboid of two liters would produce 4-500 ml bottles; a one-liter cuboid would produce 4-250 ml bottles. The unique form and design of the bottles help to support each other within their package when packaged together according to the invention.


One unique benefit of the nesting concept according to preferred embodiments of the invention is that the nesting bottles take up one-third less space on the retailer's shelves than an equal volume of standard water bottles. With retail space at a premium, this space-saving design should have broad appeal to retailers and manufacturers alike. FIG. 8 shows a comparative illustration (side view) of the amount of space six 500 ml bottles (3 liters) of water 81 take up in comparison with an equal volume of liquid using the nesting packaging concept products 82. FIG. 9 shows a comparative illustration (top view) of the amount of space a 2×3 bundle of six 500 ml bottles (3 liters) of water 91 take up in comparison with an equal volume of liquid using a four container nesting packaging product 92 according to the invention.
