Feb. 20, 1968 R. w. DIKE BOTTLE CONSTRUCTION .2 Sheets-$heet 1 Filed Aug. 8, 1966 Ila INVENTOR. Roy WDi/ke 7 W &

ATTORNEYS United States Patent 3,369,688 BOTTLE CONSTRUCTION Roy W. Dike, Mesa, Ariz., assignor to The Climalene Company, Canton, Ohio, a corporation of Ohio Filed Aug. 8, 1966, Ser. No. 570,784 8 Claims. (Cl. 215-10) ABSTRACT OF THE DISCLOSURE A cube-shaped, flexible, plastic material bottle having generally rectangular vertically extending side walls, base wall and recess wall portions forming a diagonally extending bottom recess, the recess wall portions converging downwardly, a dome-shaped top wall and an upwardly projecting, diagonally disposed tubular handle member oriented 90 with respect to the diagonal bottom recess, the median zone of each recess wall portion having ends formed in horizonal cross section with shoulder abutments, each base wall having a relatively narrow outer marginal flat portion and a relatively wide inwardly, slightly upwardly inclined concave portion connecting the marginal flat portion and one of said recess median zones.

The invention constitutes improvements upon the bottom construction disclosed in my prior Patent No. 3,214,052, issued Oct. 26, 1965; and relates to bottles, jugs, containers and the like which may be used for the bottling, storage, distribution and use of various products, for example, liquids generally, and particularly the invention relates to a new bottle construction which may be used advantageously for the distribution of liquid cleaning products, such as bleaches, ammonia and the like, with a greater facility, efficiency, safeness and usability than prior art containers heretofore used for such purpose.

The bottle construction of my prior patent differs from prior bottle constructions for such purposes in that it eliminates the upwardly opening, usually central, filling and pouring nozzle, spout or neck, and eliminates other difficulties which have existed in connection with the use of such conventional bottles.

The patented bottle provides a hollow diagonally disposed handle upon the top of the bottle, and the filling and pouring nozzle, spout or neck is located in one end thereof. A diagonally disposed recess in the bottom of the bottle also is provided to receive the handle of a similar bottle when the bottles are stacked for display, storage or shipment.

However, it has been found that when such bottles are formed of flexible plastic material, the bottle walls may bulge and particularly the botttm wall of the bottle may bulge or become somewhat rounded downwardly when filled with liquid. This bulging or rounding of the bottom wall of the bottle may permit the bottle to rock when located on a horizontal surface, thus providing some instability when the bottles are stacked for shipping, display or distribution.

The patented bottle also had a downwardly and outwardly flared recess in its bottom surface to receive the handle of the next lower bottle when stacked in a nested stack. It was found that due to the flared shape of the recess there sometimes was a tendency for the bottles to be easily displaced laterally of the recess or handle when stacked in a nested stack.

Accordingly, objects of the invention are to provide a new compact bottle construction which eliminates the described difliculties encountered in the use of the patented bottles while retaining the benefits thereof; to

provide a new bottle construction in which the bottom of the bottle is so shaped as to prevent bulging or rounding of the bottom surfaces when the bottle is filled with lqiud; to provide a new bottle construction incorporating a unique bottom wall structure, having a narow outer marginal flat portion for contact with a supporting surface with the remainder of the bottom .wall of the bottle being inclined or recessed upwardly and inwardly; and to provde a new nesting, interlocking bottle structure in which the diagonally disposed recess in the bottom of the bottle, for receiving the handle of a stacked next lower bottle, is tapered downwardly and inwardly and is formed with end shoulders.

These and other objects and advantages, apparent to those skilled in the art from the following description and claims, may be obtained, the stated results achieved, and the described difliculties overcome, by the devices, constructions, structures, arrangements, combinations, parts and elements which comprise the present invention, the preferred embodiment of which-illustrative of the best mode in which applicant has contemplated applying the principles-is set forth in the following description and shown in the drawings, and which are particularly and distinctly pointed out and set forth in the appended claims forming part hereof.

The nature of the improved compact bottle construction of the present invention may be stated in general terms as including in a bottle of a type having blowmolded flexible plastic material side, bottom and topwall means integrally connected to form a generally cubicallyshaped bottle, in which the side wall means includes generally rectangular vertically extendng side walls and connecting corners forming a generally square crosssectional shape, in which the bottom wall means includes base wall, side wall and recess wall portions forming a bottom recess extending diagonally of the square between opposite side Wall corners dividing the bottom wall means into two spaced leg cups each generally having a base formed by one of the base wall portions, in which the top wall means is formed with a dome-shaped top member and an upwardly projecting tubular handle means extending diagonally of the square between opposite side wall corners and oriented with respect to the diagonal bottom recess, and in which the tubular handle member is outwardly and downwardly flared at each end and has a reduced central tubular handle portion spaced upwardly from the dome member to provide an elongated handle opening; the combination of bottom recess wall portions each having a median zone downwardly and inwardly tapered to form a keyhole-like shaped recess in vertical cross section, each median zone having each end formed in horizontal cross section with a shoulder abutment; and the base wall of each leg cup having a narrow, outer, manginal flat portion and an inwardly upwardly inclined concave portion connecting said margial flat portion and one of said recess median zones.

By way of example, an embodiment of the improved bottle construction is shown in the accompanying drawings forming part hereof in which;

FIG. 1 is a perspective view of the new bottle construction;

FIG. 2 is a vertical sectional elevation of the bottle upon a larger scale;

FIG. 3 is a vertical sectional elevation of the bottle taken at right angles to the plane of FIG. 2;

FIG. 4 is a horizontal sectional view taken on the line 4-4, FIG. 2;

FIG. 5 is a top plan view of the bottle with parts broken in section;

FIG. 6 is a bottom plan view of the bottle;

FIG. 7 is a View illustrating a plurality of bottles stacked in an interlocked nested stack; shown on a smaller scale;

FIG. 8 is a larger scale, horizontal sectional view taken on the line 8-8, FIG. 7; and

FIG. 9 is a view similar to FIG. 7 showing the bottles filled with liquid, parts being broken in section for the purpose of illustration.

Referring now more particularly to the embodiment of the invention illustrated in the drawings, in which similar numerals refer to similar parts throughout the various figures, the improved bottle construction is illustrated as comprising substantially a cube modified in the manner to be described to achieve the new concepts of the invention.

The bottle 1 may be made by usual blow-molded procedures preferably of flexible plastic material so as to be light in weight, strong, not readily breakable as is glass, and with a minimum tendency to mar, scratch or dent another object upon accidental contact therewith.

Although the bottle shape and the inter-related shape and arrangement of its components are of fundamental importance, the size of the bottle may be varied to provide bottles having various volumetric capacities such as one quart, ne-half gallon and one gallon sizes.

The bottle 1 is formed of a number of integrally connected walls comprising side wall means generally indicated at 2, bottom wall means generally indicated at 3 and top wall means generally indicated at 4. The wall means 2, 3 and 4 form a closed bottle or container having a filling and pouring neck 5 closed by a usual bottle cap 6.

The side wall means 2 includes a plurality of generally rectangularly arranged, vertically extending side walls, 7, 8, 9 and 10 which are connected by rounded vertical corners 11 and 11a between adjacent side walls. Thus, the bottle 1 is generally square in cross section, as best illustrated in FIGS. 5, 6 and 8. The side walls 7, 8, 9 and 10 are preferably provided with a slight panel indentation 12 for receiving a label.

The top wall means 4 preferably includes a generally rectangular, convex, dome-shaped top member 13 connected by rounded corners 14 with the bottle side walls 7, 8, 9 and 10 and corners 11 and 11a. The top wall means 4 also includes an integral, tubular handle, generally indicated at 15, extending diagonally between opposite side wall corners 11a and oriented 90 with respect to the diagonal bottom recess to be later described.

The tubular handle 15 has a reduced tubular median portion -16 terminating in outwardly, downwardly flared end portions 17 and 18 connected with the member 13 adjacent the bottle corners 11a. The reduced median handle portion 16 is spaced upwardly from the dome member 13 as shown, providing an elongated handle opening 19.

As shown, the bottle filling and pouring neck 5 is connected with the flared handle end portion 18 and thus locates the pouring opening 20, formed by the neck 5, below the top of the handle member 15.

As best shown in FIG. 8, the reduced median handle portion 16 of the handle has a smaller cross-sectional area than any portion of the handle 15 at either side of the center, above or beyond the handle opening -19. The increasing size of the handle 15 at either side of the central portion 16 blends smoothly into the flared handle portions 18 and 19.

The bottom wall means 3 preferably includes base wall portions, indicated generally at 21 and 22, side portions 23, 24, and 26, and recess portions 27 and 28. The recess portions 27 and 28 form a concave bottom recess 29 extending diagonally between opposite side wall corners 11.

As best shown in FIG. 6, the recess 29 is of the smallest cross section at its center, being flared gradually outward on each side of the center and terminating in the enlarged end portions 30, at opposite ends, adjacent the corners 11 of the bottle.

As best shown in FIG. 8, the recess 29 is of smallest cross section at its median portion and gradually increases in width toward each end in the same manner as the median portion of the handle 15.

The recess 29 divides the bottom wall means 3 into two spaced leg cups, generally indicated at 31 and 32, the leg cups being generally triangular in cross section as best shown in FIGS. 4, 6 and 8. The leg cup 31 has base wall portion 21 as its bottom wall, and side portions 23 and 24 and recess portion 27 as its side walls.

Leg cup 32 similarly has base wall portion 22 as its bottom wall, and portions 25, 26 and 28 as its side walls. As shown, the cup side portions 23 and 24 and the enlarged recessed end portions 30 of the leg cup 31, and the side portions 25 and 26 and the enlarged recessed end portions 30 of the leg cup 32 taper upwardly outwardly from the base wall portions 21 and 22 respectively, by slightly rounded corners 33 and 34.

The side portions 23 and 24 of leg cup 31 connect with the bottle side walls 7 and 9 by slightly rounded corners 34, and similarly the side portions 25 and 26 of the leg cup 3?; connect with the bottle side walls 8 and 10, by slightly rounded corners 35.

Th side wall portions (FIGS. 2 and 4) of diagonal recess 29 have median zones 29a and 29b that converge downwardly and inwardly to form a keyhole-like shape for the recess 29 in vertical cross section as Well shown in FIGS. 1, 2, 7 and 9.

These median Zones 29a and 2% (FIGS. 4 and 6) have ends formed in horizontal cross section with a shoulder abutment 290. The lower extremity of the keyhole-shape of recess 29 is narrowest at 36, the width being slightly greater at this location than the width of the upper portion of handle 15 at any corresponding complementary portion (FIG. 8).

Thus, the shoulder abutments 29c of the bottom wall recess portion formation engage the flared handle portions 17 or 18 when a number of bottles are stacked one upon another and force is applied tending to slide one bottle laterally along the handle next below.

The bottom or base walls 21 and 22 of the leg cups 31 and 32 are formed with flat outer marginal V-shaped portions 37 around the outer edges of each base Wall 21 and 22 (FIGS. 4, 6 and 8). Each base wall then is inclined gradually upwardly and inwardly to form a concave portion 38 which connects the marginal flat portion 37 through an abruptly upwardly and inwardly angled portion 39 at 36 with one of the median zones 29a or 29b (FIG. 2).

With this construction, when the bottle is empty, as shown in FIG. 2, only the narrow outer marginal fiat portions 37 of the base walls 21 and 22 of the leg cups will contact with the floor or shelf or other surface by which it may be supported.

Even when the bottle is filled with liquid, as shown in FIG. 9, the Weight of the liquid upon the base walls of the cup legs 31 and 32 will not bulge the inner portions 38 thereof downward sufliciently to contact the supporting surface therefor.

As best shown in FIG. 9, a plurality of the improved bottles, filled with liquid, may be stacked on one another to consider-able height, without danger of the stack becoming unstable because of downwardly bulged or rounded bottom walls of the flexible bottles due to the Weight of the liquid therein.

The improved bottle retains all of the benefits and advantages disclosed in my prior patent above referred to, and in addition the improved bottom wall and recess wall constructions avoid difiiculties that have been encountered.

In the foregoing description, certain terms have been used for brevity, clearness and understanding, but no un necessary limitations are to be implied therefrom beyond the requirements of the prior art, because such terms are used for descriptive purposes and are intended to be broadly construed.

Moreover, the description and illustration of the vention is by way of example, and the scope of the invention is not limited to the exact structure shown, because the sizes and shapes of the bottle and its components may be varied to provide other structural embodiments, without departing from the fundamental principles of the invention.

Having now described the features, discoveries and principles of the invention, the construction, advantages and use of a preferred form thereof, and the advantageous, new and useful results obtained thereby; the new and useful discoveries, principles, devices, constructions, structure's, arrangements, combinations, parts, elements, cooperative relationships, and .mechanical equivalents obvious to those skilled in the art are set forth in the appended claims.
