Description




TECHNICAL FIELD




This invention relates to low depth, plastic cases used for carrying bottles and, specifically, to a new case construction for individual bottles.




BACKGROUND




It is well known to utilize plastic cases for carrying glass or plastic bottles of various sizes and shapes. Such cases are often designed to carry a particular size bottle in what is sometimes referred to as a “low-depth” case, i.e., a case having relatively low peripheral wall (side and end walls) with the bottles extending above the peripheral wall. This means that the bottles themselves support adjacent cases when vertically stacked. These cases also have underside profiles that provide recesses for the bottle tops of underlying cases in order to add stability. Another feature of these cases is the ability to nest when empty, thereby conserving space during shipping and storage. Examples of prior low depth cases may be found in U.S. Pat. Nos. 5,842,572; 5,823,376; 5,184,748 and 5,060,819.




Continuing concerns relate to material costs, case strength, bottle support and stability as well as the handling of the cases empty or filled.




SUMMARY OF THE INVENTION




This invention provides a low depth case that is designed for strength, good bottle support and stability when the crates are used individually, but also when several filled crates are stacked, one on top of the other. The various bottle support surfaces within the case are designed to minimize surface contact, and thereby also minimize bottle surface abrasion. The case disclosed herein is also designed to permit cross stacking and to facilitate pulling the top case off a stack of filled similar cases.




Specifically, the case in accordance with this invention is of one piece molded plastic construction, and includes a relatively flat open-grid type bottom which is connected about its periphery to a pair of side walls and a pair of end walls (also generally referred to as a peripheral case wall). The peripheral case wall has upper and lower regions, with the upper region including a solid band or rail and the lower region including a plurality of spaced panel sections. In other words, the upper band or rail is supported by the plurality of side and end wall panel sections that are located at laterally spaced apart locations about the periphery of the lower region of the case. As a result, windows are formed in the lower region of the peripheral case wall. The case is sized to accommodate four longitudinal rows of 20 oz. bottles with six bottles in each longitudinal row. Alternatively stated, the case accommodates six transverse rows of bottles with four bottles in each transverse row. The case will, however, also accommodate bottles of different size, e.g., 16 oz., 24 oz., etc. but having substantially identical diameters. The open-grid case bottom is designed to provide a distinct, albeit flat, bottle supporting platform for each bottle in the case.




Interiorly of the case peripheral wall, four columns extend upwardly from the case bottom in a symmetrical pattern, each column lying in the center of an array of four bottle supporting platforms, but with no columns located along either of the longitudinal or transverse center lines of the case. As a result, 16 of the 24 bottles will be supported by one side of one column. The remaining eight bottles receive lateral support only from the side end or end walls (and, of course, from adjacent bottles).




The four columns extend upwardly only through the height of the lower region, i.e., to the bottom of the upper peripheral rail. In addition, it will be appreciated that the case configuration would otherwise permit carrying of four six-pack cartons, but the presence of the columns within the interior of the case prevents the carrying of such cartons. Thus, the case is designed for use only with individual bottles, or with multi-packs having top grips.




As already mentioned, the upper surface of the case bottom is flat (except for the columns), with the open grid designed to provide bottle supporting areas or “platforms” for each bottle received within the case. The underside of the case bottom, however, is provided with recessed areas underlying each of the bottle supporting platforms, for receiving the bottle caps of bottles (or tops of the bottles if the latter are empty) contained in an underlying case, when the cases are vertically stacked. These recesses are formed with flat center areas, larger than the bottle tops or caps, thus providing stability but allowing room for the bottles to adjust, particularly when the cases are cross-stacked, an arrangement which results in the bottles of adjacent cases being slightly offset.




The side walls and end walls that make up the peripheral case wall are generally similar except for the presence of handle openings formed in the end walls. The band or rail in the upper region of the peripheral case wall is of alternating double/single walled construction, whereas the side and end wall panel sections in the lower region are of single wall construction. Thus, the peripheral band or rail overhangs the lower side and end wall panel sections. The lower side and end wall panel sections are also tapered slightly inwardly to facilitate stacking of similar empty cases. When empty cases are stacked, the lower, outer edge of the upper peripheral rail of one case rests on the upper edge of the upper peripheral rail of the underlying case. Thus, the lower side and end wall panel sections nest only within the upper rail of the underlying case, such that the case bottom does not engage the columns of the underlying case.




The interior of the peripheral case wall is formed with a repeating surface pattern configuration in both the upper and lower regions thereof. The interior of the lower side and end wall panel sections are each provided with a pair of relatively thick, vertically extending and laterally spaced ribs that provide support, respectively, for two bottles on adjacent support platforms. The bottle supporting surface of each rib is a concavely shaped edge that faces toward the center of the respective bottle supporting platform.




The interior of the upper rail or band is interrupted by a plurality of spaced inwardly directed buttresses, each of which is centered directly over a respective window in a lower side or end wall, and hence, laterally offset from the pairs of ribs on the lower side or end wall panel sections. The interior surface of each buttress is concave in an inward facing direction, and tapers slightly outwardly and upwardly in an upper section of the buttress. This tapered region is provided with a pair of thin upstanding, laterally spaced ribs, each having a convex facing surface. These ribs continue down through the lower section of the buttress, along the vertically concave surface. The ribs in the upper section of the buttress merely serve to guide a bottle as it is inserted into the case. Once seated in the case, the bottle is laterally supported in part by both of the thin vertical ribs in the lower section of the buttress.




Each column within the interior of the case has four sides of equal width, so that the column has an essentially square cross sectional shape. The columns are skewed, however, by approximately 45°, so that the corners of each column project toward four adjacent bottle supporting platforms. Each of the column sides is also formed with a pair of vertically extending ribs extending upwardly from the case bottom to the top of the column. Each pair of ribs provides line or tangential support for a bottle seated in a respective one of the four adjacent bottle supporting platforms.




Thus, it will be appreciated that the support surfaces for bottles seated within the case are all configured as relatively thin ribs, minimizing surface contact with the bottles themselves, and thereby also minimizing the possibility of abrasion of the bottle surfaces. The bottles are also less likely to be jammed or wedged within the case, because surface contact with the bottles has been minimized, thereby also reducing friction.




Accordingly, in its broader aspects, the present invention relates to a case for carrying a plurality of bottles comprising a pair of side walls and a pair of end walls connected to a case bottom having a plurality of bottle supporting platforms, the side walls and the end walls having a lower part including a plurality of panels separated by windows and an upper part including a substantially solid band, the solid band in the end walls having handle-forming openings therein; wherein the panels are each provided on interior surfaces thereof with a pair of relatively thick, vertically extending and laterally spaced ribs, the ribs having edges facing radially towards centers of adjacent bottle supporting platforms.




In another aspect, the present invention relates to a case for carrying a plurality of bottles comprising a pair of side walls and a pair of end walls connected to a case bottom having a plurality of bottle supporting platforms, the side walls and the end walls having a lower part including a plurality of panels separated by windows and an upper part including a substantially solid band, the solid band in the end walls having handle-forming openings therein; and wherein the solid band is provided on an interior surface thereof with a plurality of vertically extending buttresses, each directly above a respective window; and further wherein each of the buttresses is provided with a pair of vertically extending ribs centered on an adjacent bottle supporting platform.




Other objects and advantages will become apparent from the detailed description that follows.

DETAILED DESCRIPTION OF THE DRAWINGS




With reference initially to

FIGS. 1-4

, the case


10


is of one-piece molded plastic construction, with a pair of side walls


12


,


14


; a pair of end walls


16


,


18


that together comprise the case peripheral wall; and a bottom


20


. The case is configured to include four longitudinal rows LR


1


, LR


2


, LR


3


and LR


4


of bottle supporting platforms, with six platforms in each longitudinal row. Alternatively, there are six transverse rows TR


1


, TR


2


, TR


3


, TR


4


, TR


5


and TR


6


with four bottle supporting platforms in each transverse row. Four columns


22


,


24


,


26


and


28


extend upwardly from the case bottom


20


, in a symmetrical pattern, best appreciated from

FIG. 2

which illustrates one half of the case, the other half being a mirror image thereof. Columns


22


,


24


are located between longitudinal rows LR


1


and LR


2


and between transverse rows TR


2


, TR


3


, and TR


4


, TR


5


, respectively. Thus, there are no columns along either the longitudinal or transverse center lines of the case. As further described herein, each column


22


,


24


,


26


,


28


lies in the center of an array of four bottle supporting platforms, so that sixteen of the twenty-four bottles will be supported laterally by one side of one column. The remaining eight bottles are located in transverse rows TR


1


and TR


6


and receive lateral support from the side walls


12


,


14


and/or end walls


16


,


18


as also described further herein. Of course, all of the bottles provide some degree of lateral support for each other.




The case bottom


20


is an open grid made up of a pattern of straight and circular ribs. The upper side of the case bottom is flat while the underside is formed with recesses as described further herein. The grid is substantially symmetrical, allowing for slight variations along the side and end walls and in the corners. For the sake of simplicity, only one bottle supporting platform need be described in detail. Thus, as best seen in

FIG. 2

, each bottle supporting platform is defined by a square made up of longitudinal ribs


30


and transverse ribs


32


, with a diamond pattern


34


in each corner (some of which also form part of respective columns


22


,


24


,


26


and


28


). Within the center of each platform, there are a pair of concentric, annular ribs


36


,


38


. Radial ribs


40


extend from the outer annular ribs


36


to the diamond patterns


34


in respective corners of the platform. It will be appreciated that the ribs


30


,


32


and diamond patterns


34


are “shared” with adjacent platforms. In addition, longitudinal and transverse pairs of ribs


42


,


44


, respectively, extend from the boundary of each platform through the outer annular rib


36


to the inner annular rib


38


, centered on the sides of the square platform boundary. Each platform thus has a center hole


46


as defined by the radially inner annular rib


38


. For ease of understanding, reference numerals associated with the bottle supporting platform as described above, appear primarily in

FIG. 2

, and are spread over adjacent platforms, for example, platforms


48


,


50


and


52


, due to the limited space for the reference numerals.




As already mentioned, the upper surface of the case bottom is flat with the exception of the four identical columns


22


,


24


,


26


and


28


. The description below will be primarily with respect to the columns, as best seen in

FIGS. 1

,


2


and


5


.




Each column has four sides


54


of equal width, so that the column walls have essentially a square cross-sectional shape. The sides


54


are oriented similarly to the diamond patterns


34


in the corners of the bottle supporting platforms. As a result, each side


54


faces toward the center of a respective bottle supporting platform. In other words, each side


54


is perpendicular to a line drawn between the center hole


46


of a platform and the center of the respective column. Each of the sides


54


is also formed with a pair of ribs


56


,


58


extending upwardly from the case bottom to the top of the column. Note that both the sides


54


of the column


28


and the four pair of ribs


56


,


58


taper inwardly at the upper end of the column, terminating at a flat top surface


60


, the latter having a center hole


62


formed therein. Each pair of ribs


56


,


58


provides line (or tangential) support for a bottle seated in the four adjacent bottle supporting platforms as described further herein.




The side walls


12


,


14


and end walls


16


,


18


of the case are generally similar except for the presence of handles


68


,


70


formed in the end walls. The side and end walls generally have upper and lower sections. The lower section includes a series of spaced panels


72


, separated by “windows”


76


. The windows


76


extend vertically only to the lower edge of the upper section that is formed as a substantially uniform and continuous solid “band” (except for the handle areas) or rail


78


supported by the panels


72


. The band


78


, as clearly shown in

FIGS. 1

,


3


and


4


defines a continuous top edge


79


of the case, having a uniform height. A slightly indented, substantially rectangular region


80


may be formed in the upper band


78


, generally centered in each of the side walls


12


,


14


for application of labels or other indicia.




The upper band or rail


78


is also formed with handles


82


,


84


in the end walls created by through openings in the end walls, to thereby create the respective handles


68


,


70


, allowing the user to grasp the case at opposite ends.




With reference especially to

FIGS. 6 and 8

, the interior of the side walls


12


,


14


and end walls


16


,


18


is formed with a repeating surface pattern configuration in the upper and lower sections thereof. Thus, the interior of each of the panels


72


(except for the panels in the corners of the case) are formed with a pair of inwardly projecting, relatively thick ribs


86


,


88


. One corner of each rib is formed with a concave bottle engaging edge surface


90


facing radially towards the center of the adjacent bottle supporting platform. In other words, the ribs


86


,


88


of each panel


72


support adjacent bottles, whereas the two ribs on either side of a window


76


support the same bottle. The rib surfaces


90


are thin, substantially vertical surfaces with a curvature that generally conforms to the curvature of the bottle.




The upper ends of the ribs


86


,


88


included tapered surfaces


92


,


94


, respectively, that extend upwardly to merge smooth with a tapered surface


96


on the interior of the upper band


78


that, in turn, connects with a vertical surface


98


and that extends to the upper edge of the case.




The interior surface of the corner panels


74


are smoothly curved and are devoid of any ribs or other protrusions, as best seen in FIG.


2


.




The interior of the upper band or rail


78


is interrupted by a plurality of spaced, inwardly directed, buttresses


100


(see also FIG.


7


), each of which is directly centered over a respective window


76


. In other words, buttresses


100


are arranged so as to lie between and above the side wall and end wall panels


72


, and extend from the windows


76


to the upper edge of the case. Each buttress


100


is concave in an inward facing direction, and tapers slightly outwardly and upwardly in an upper area


102


delineated by a horizontal crease


104


, as best seen in FIGS.


1


and


6


-


8


. This tapered region is provided with a pair of relatively thin, generally vertical ribs


106


,


108


, each rib having an inwardly facing (i.e., facing into the case interior) convex surface. These ribs are centered with respect to the respective bottle receiving platform. These convex surfaces of ribs


106


,


108


thus provide essentially “line” or tangential support for any bottle surface engaged thereby, although these ribs generally do not contact the bottles once they are seated on their respective platforms. They do, however, serve to guide the bottles as they are inserted into the case. The lower area


103


of the buttresses


100


, below the crease


104


, are vertical and concave, with even thinner vertical ribs


110


,


112


continuing from the wider ribs


106


,


108


, downwardly to the windows


76


. These thin vertical ribs


110


,


112


provide tangential support for bottles seated on the platforms along the side and end walls of the case.




Similar buttresses


114


are provided on opposite sides of each handle opening


82


and


84


, but the width of the end wall buttresses is less than those in the side walls. Nevertheless, the buttresses


114


are also centered with respect to their respective bottle platforms in the corner of the case.




Along each of the handle grip portions


86


and


88


, there are a pair of inward facing projections


116


which serve the same purpose as buttresses


100


and


114


and are likewise centered on adjacent bottle support platforms.




With specific reference now to

FIGS. 8 and 9

, it will be appreciated that the upper peripheral rail or band


78


is double wall construction in the area of the buttresses


100


,


114


(as defined by band


78


and buttress surfaces


102


,


103


), and of single wall construction in the areas between the buttresses, (as defined by surfaces


98


). The lower panel sections


72


, on the other hand, are of single wall construction, noting that the ribs


92


,


94


are hollow as evident from the exterior of the panels (see

FIGS. 1

,


3


,


4


and


10


). This arrangement results in the upper peripheral rail or band


78


“overhanging” the lower panels


72


, and establishing a peripheral edge


116


by which the case is supported when stacked. In other words, the edge


116


of one case rests on the upper edge of an underlying case when stacked empty. The interface along edge


116


provides the only nesting support for adjacent empty cases.




As described above, the columns


22


,


24


,


26


and


28


extend to a height just below the upper edge of the windows


76


, and are open at their lower ends. In an alternative embodiment, however, a pair of cross ribs


64


,


66


may be provided within the otherwise hollow interiors of columns


65


,


67


, as best seen in

FIGS. 13 and 14

. In this case, the columns


65


and


67


are raised in height, extending into the area of the upper peripheral band


78


so that the cross ribs


64


,


66


in column


65


of an upper case rest on the tops of the columns


67


of an underlying empty case.




Turning now to

FIGS. 5

,


10


and


14


, the underside of the case bottom


20


will be described. While the patterns of ribs are identical to the upper side of the case bottom, the underside is not smooth or flat. Rather, the underside is relieved to form pockets for receiving the tops of bottles in underlying cases when two or more of such cases are vertically stacked. For ease of understanding, it is noted initially that the overall recess pattern on the underside of the case bottom


20


is symmetrical, with one half of the case bottom being a mirror image of the other half, using the transverse rib


32


between transverse rows TR


3


and TR


4


as the center line of the case. Nevertheless, for the respective halves, the platform undersides or recesses in each row is different. Thus, the innermost transverse rows TR


3


and TR


4


have one underside recess pattern; the intermediate transverse rows TR


2


and TR


5


have a second underside recess pattern, and outside transverse rows TR


1


and TR


6


have a third underside recess pattern.




It will be appreciated that the transverse and longitudinal ribs


30


and


32


bordering each platform, as well as the diamond patterns


34


and lowermost edge of the columns


22


,


24


,


26


and


28


, all lie in the same plane and form the lowermost surface of the case bottom


20


. This lowermost surface will also be referred to as the bottom plane. Within each platform area, certain additional ribs in the bottom grid also lie in the bottom plane as discussed further below.




As best seen in

FIGS. 1 and 5

, the bottom grid includes, along the side walls


12


and


14


, a plurality of longitudinal rib segments


118


, the lower edges of which lie in the bottom plane. These rib segments


118


define the lower edge of the windows


76


, and are “set in” relative to the base portions of the lower panels


72


. The ribs


118


lie parallel to a plurality of longitudinal rib segments


120


that lie to the inside of the interior ribs


86


,


88


. Note that transverse ribs


32


intersect the segments


120


. Except as noted below, rib segments


118


,


120


and ribs


32


lie in the bottom plane. Transverse or end wall rib segments


124


extend along the end walls, similar to longitudinal or side wall rib segments


118


except that, as explained in greater detail below, rib segments


124


lie in the recess plane. Along the end walls, transverse segments


122


correspond to longitudinal segments


120


. Note also that the longitudinal rib segments


118


merge with transverse rib segments


124


in the corners of the case, where the side segments


118


taper from the bottom plane to the recess plane as they join with end segments


124


. The peripheral edges of the bottom grid where the grid intersects with the exterior surfaces of the side and end panels


72


are beveled to eliminate sharp edges and to facilitate the stacking of empty cases.




With reference also to

FIGS. 11 and 12

, in transverse rows TR


3


and TR


4


, the underside of the bottom (under each platform) is formed with a flat recessed area or recess (lying in a “recess plane”) bounded by the annular rib


36


. Since the diameter of rib


36


is considerably larger than the diameter of a bottle cap, it follows that underlying bottle tops or caps have room to adjust within the circular recessed area. From the rib


36


, the surrounding ribs


40


,


42


and


44


taper downwardly and outwardly (viewing the case in an upright orientation), terminating in flat portions lying within the bottom plane and connecting to the ribs


30


,


32


and diamond pattern


34


.




In rows TR


2


and TR


5


, the recesses are modified to facilitate removal of one case from another in a lateral sliding fashion. Specifically, the annular ribs


36


in these rows are lowered (again, considering the case in a normal upright orientation) through approximately 180° so as to lie in the bottom plane. Specifically, annular rib


36


moves from the recess plane to the bottom plane via diametrically opposed opposite taper or ramp portions


126


, extending between respective pairs of transverse ribs


44


. The portion in the bottom plane is that part closer to the center line


32


of the case. To the right of annular rib


36


on the platform TR


5


(as viewed in FIGS.


5


and


11


), the pair of longitudinal ribs


42


remain substantially in the recess plane, tapering slightly to meet the transverse rib


32


. Note that between the diamond patterns


34


to the right of the recess on the platform at TR


5


, LR


2


, the transverse rib


32


is shaved to include a center section


128


(between the ribs


42


) that lies between the recess plane and the bottom plane. The pair of ribs


42


continue to taper through the rib


32


downwardly to the bottom plane in the adjacent platforms in TR


6


).




For the recesses at LR


1


, TR


2


and TR


5


; and LR


4


, TR


2


and TR


5


, a similar shaved section


128


of the transverse rib


32


extends between diamond pattern


34


and one of the longitudinal rib segments


120


at the base of the ribs


86


,


88


closest the end wall. Note also that for longitudinal rows TR


1


and TR


4


, the radial ribs


40


that would otherwise be closest the side walls


12


and


14


are replaced by transverse rib segments


130


that intersect the annular rib


36


and that connect the offset longitudinal rib segments


118


and


120


. Segmented rib


118


at TR


5


(and TR


2


) tapers from the shaved transverse rib


32


toward the recess plane as it intersects the rib segment


130


. At the same time, radial rib


40


(on the right hand side of the platforms in TR


5


and TR


2


) extends from annular rib


36


farther in the recess plane than corresponding radial ribs


40


in TR


4


before tapering to the bottom plane at the diamond pattern


34


. The result of this configuration is that the recesses in platforms in TR


5


(and TR


2


) are elongated toward the nearest end of the case and are thus asymmetrical with respect to the platform itself. This arrangement facilitates sliding of the case in a direction parallel to the longitudinal axis of the case, recognizing that the case must slide over bottle caps received in the various recesses.




In row TR


6


(and TR


1


), the recess is continued in the recess plane to the end edge of the case. Specifically, the annular rib


36


is identical to that in TR


5


(and TR


2


), with diametrically opposed tapers at


132


leading from the bottom plane to the recess plane. The longitudinal rib pair


42


,


42


; corner radial rib


134


, longitudinal rib segment


136


, and the end rib segments


124


all lie in the recess plane, providing clear and open access to the recesses in TR


6


(and TR


1


). Here again, the goal is to facilitate sliding the case off a stack of cases. This is especially important when the handler must reach above his or her head to grasp the top case in the stack and slide it off the stack.




While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not to be limited to the disclosed embodiment, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
