Abstract
A container includes a body defining a chamber and a neck region. A straw is disposed within the chamber. The straw is inserted through the neck region and into the chamber prior to filling the chamber and is trapped or wedged between a first portion of the container and a second portion of the container by mechanical engagement with the container. The position of the straw within the chamber does not interfere with the filling of the container. When filling has been completed, the body of the container is manipulated to release the straw from its mechanical engagement with the container and position it within the neck region.
Description




FIELD OF THE INVENTION




The present invention relates to container for beverages. More particularly, the present invention relates to beverage containers having a self-contained straw which automatically extends through the opening when the container is opened.




BACKGROUND OF THE INVENTION




Various designs have been proposed in the prior art for placing a straw within a beverage container that becomes accessible to the user when the beverage container is opened. Some of the prior art designs rely upon the user to manipulate the container after it has been opened to align the straw with the opening. Once aligned, the buoyancy of the straw and/or a float attached to the straw extend the straw through the opening. Still other prior art designs include a mechanism which has the ability to locate the straw within the container. The act of opening the container imparts a force and/or motion to the mechanism which then positions the straw in line with the opening. Again, buoyant forces acting on the straw extend the straw through the opening once it has been aligned.




While the prior art straw dispensing mechanisms remain technologically and commercially viable, the continued development of these systems has been directed to lowering the complexity and costs associated with these mechanisms while simultaneously maintaining and/or improving upon the reliability of these mechanisms.




SUMMARY OF THE INVENTION




The present invention provides the art with a unique dispensing mechanism which simplifies the way in which the straw is retained during the filling process while simultaneously ensuring that the straw will be available to the user upon opening the container.




Other advantages and objects of the present invention will become apparent to those skilled in the art from the subsequent detailed description, appended claims and drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring now to the drawings in which like reference numerals designate like or corresponding parts throughout the several views, there is shown in

FIG. 1

a beverage container incorporating an internal straw in accordance with the present invention which is designated generally by the reference numeral


10


. Beverage container


10


is a generally rectangular parallelepiped container having a first pair of generally parallel side walls


12


and


14


and a second pair of generally parallel side walls


16


and


18


. While container


10


is shown as a generally rectangular parallelepiped container, it is to be understood that container


10


could be manufactured in additional shapes including but not limited to cylindrical containers, square containers or the like. Walls


12


,


14


,


16


and


18


form a generally rectangular structure having an internal chamber


20


which is closed by a bottom wall


22


and a top wail


24


. Container


10


may be manufactured by any of the conventional manufacturing techniques including but not limited to extrusion blow molding, reheat stretch blow molding or injection stretch blow molding. When being manufactured by extrusion blow molding, the preferable materials include polyolefins such as high density polyethylene (HDPE), polyethylene terephthalate (PET) or polyvinyl chloride (PVC). When either the reheat stretch blow molding or the injection stretch blow molding are being used to manufacture container


10


, the preferred materials include PET or polypropylene (PP).




Top wall


24


includes a cylindrical extension


26


which defines a neck region


28


through which fluid that is stored in beverage container


10


can be dispensed. Neck region


28


is shown being closed and sealed by a threaded cap


30


but it is to be understood that neck region


28


can be closed and sealed by other means known in the art including but not limited to a snap cap closure or an induction bonded foil seal closure. Top wall


24


is shown being slightly angled towards neck region


28


to provide a cone of entry into neck region


28


from chamber


20


.




A straw


32


is disposed within chamber


20


and, as shown in

FIG. 1

, is disposed adjacent to threaded cap


30


. Straw


32


comprises a lower tubular section


34


, a lower pleated section


36


, a middle tubular section


38


, an upper pleated section


40


, an upper tubular section


42


and a float


44


. Lower pleated section


36


provides the ability for straw


32


to bend and be preloaded within chamber


20


. Upper pleated section


40


provides the ability for straw


32


to be extended for the convenience of the user. Float


44


is attached to middle tubular section


38


and provides buoyancy for straw


32


to urge it against threaded cap


30


after chamber


20


of container


10


has been filled with a fluid. If additional buoyancy is needed for straw


32


, a second float


46


can be attached to straw


32


as shown in phantom in

FIG. 1

where float


46


is attached to lower tubular section


34


of straw


32


.




Referring now to

FIG. 3

, container


10


is shown prior to being filled with the fluid with straw


32


being located and retained within chamber


20


. Neck region


28


is a stepped opening which defines a generally cylindrical wall


50


and an annular step


52


. Prior to filling, straw


32


, in a straight condition, is inserted into chamber


20


through neck region


28


until the end of lower tubular section


34


contacts a lower corner


54


of container


10


. In order to secure straw


32


within chamber


20


, lower corner


54


is preferably defined by one of the first parallel side walls


12


and


14


, one of the second parallel side walls


16


and


18


, and bottom wall


22


as shown in FIG.


2


. When the end of lower tubular section


34


contacts corner


54


, straw


32


flexes or bends at lower pleated section


36


and the upper end of upper tubular section


42


is snapped or wedged into annular step


52


to retain straw


32


within chamber


20


as shown in FIG.


3


. Straw


32


is held against annular step


52


due to the elasticity of lower pleated section


36


which maintains the tendency to spring back towards a position where straw


32


is once again straight.




Once container


10


has been filled with the appropriate fluid and threaded cap


30


or another cap, is secured to extension


26


to seal neck region


28


, walls


12


,


14


,


16


and/or


18


are squeezed or manipulated by suitable means in order to release the upper end of upper tubular section


42


from annular step


52


into the cone of entry and direct it into neck region


28


. In the alternative, container


10


can be tilted or otherwise manipulated with or without the squeezing of one or more walls


12


,


14


,


16


and/or


18


to release the upper end of upper tubular section


42


from annular step


52


. Once the upper end of upper tubular section


42


enters neck region


28


defined by cylindrical wall


50


, the buoyancy of float


44


urges straw


32


against threaded cap


30


as shown in FIG.


1


.




Referring now to

FIG. 4

, when threaded cap


30


is removed, straw


32


will rise through neck region


28


due to either the spring action of lower pleated section


36


which will have a tendency to straighten straw


32


, the buoyancy of float


44


or both the spring action and the buoyancy. This movement of straw


32


through neck region


28


conveniently and automatically positions straw


32


for the convenience of the user. As shown in

FIG. 3

, the preflexed condition of straw


32


means that float


44


will propel straw


32


upwards such that upper tubular section


42


will traverse the cone of entry and neck region


28


obliquely and will not rise with the axis of the straw parallel with the axis of the bottle. Thus, straw


32


will remain generally in the position shown in FIG.


4


and will not have the tendency to bob up and down within neck region


28


.





FIGS. 5 and 6

illustrate the convenience provided by the generally rectangular parallelepiped shape of container


10


in supplying a multi-container pack


60


which comprises a lower carton tray bottom


62


, an upper carton tray top


64


and a shrink wrap


66


or other retaining package for pack


60


. Shrink wrap


66


also provides a convenient location for colorful labeling and/or advertising.

illustrates a beverage container incorporating an internal straw in accordance with another embodiment of the present invention which is designated generally by the reference numeral


110


. Beverage container


110


is the same as beverage container


10


with the exception that top wall


24


includes a cylindrical extension


126


which defines a neck region


128


through which fluid stored in beverage container can be dispensed. Neck region


128


is the same as neck region


28


except that generally cylindrical wall


50


defines an annular step


152


which is centrally located within wall


50


rather than being located adjacent the lower end of wall


50


. The function and operation of container


110


is the same as that for container


10


.

illustrates a beverage container incorporating an internal straw in accordance with another embodiment of the present invention which is designated generally by the reference numeral


210


. Beverage container


210


is the same as beverage container


10


with the exception that top wall


24


includes a cylindrical extension


226


which defines a neck region


228


through which fluid stored in beverage container can be dispensed. Neck region


228


is the same as neck region

except that generally cylindrical wall


50


defines an annular ridge


252


which is located at the lower end of wall. The function and operation of container


210


is the same as that for container


10


. This embodiment provides the advantage that straw


32


will be located away from neck region


228


prior to container


210


being filled with a fluid. This position of straw


32


allows total access to neck region


228


without having to avoid straw


32


with the filling mechanism.

534


contacts the inner surface of cylindrical wall


512


. Initially, lower pleated section


536


will be angled such that the end of lower tubular section


534


contacts bottom wall


522


and is deflected towards cylindrical wall


512


. The insertion of straw


532


continues until lower pleated section


536


snaps or wedges below shoulder


550


defined by the lower annular groove


514


to retain straw


532


within chamber


520


.




Once container


510


has been filled and cap


530


is secured to neck region


528


, cylindrical wall


512


is squeezed or manipulated by suitable means to release lower pleats


536


from shoulder


550


to position straw


532


similar to that shown in

FIG. 1

for straw


32


.




When cap


530


is removed, straw


532


will rise through neck region


528


due to the buoyancy of float


544


, the spring action of upper pleated section


536


or both. The movement of straw


532


through neck region


528


positions straw


532


similar to that shown in

FIG. 4

for straw


32


.




In any of the above described embodiments, the rate of rise of the straw is controlled by the ability of the float to lift the weight of the device which will ultimately reside above the liquid level and above the float as well as to overcome drag and viscous forces which will retard the rate of rise of the device.




It is well known to those skilled in the art that buoyancy in the float and the buoyancy of the straw produces the lift to raise this weight above the fluid level in the container. Initially, one may presume that the amount of buoyancy required to lift this weight is only somewhat greater than the weight or the object to be lifted.




The inventors of the present invention have determined that to adequately raise the weight at a rate which is acceptable, the range for lift buoyancy which produces an acceptable rate of rise is between two and six times the weight which is to be lifted. Preferably, this range is between three and five times the weight to be lifted and more preferably this range is between four and five times the weight to be lifted. It has been found that a buoyancy of one to two times the weight to be lifted will raise the device but at a speed rate on which is too slow to be effective.




The desired rate of rise for the device is in the range of 0.2 to 3.0 inches per second. Preferably, this range is between 1.0 and 2.5 inches per second and more preferably this range is between 1.5 to 2.0 inches per second. These ranges are achieved by having the lift buoyancy to weight ratios indicated above.




Another feature of the present invention is illustrated in FIG.


13


. Beverages are being supplied in larger sized bottles and the size of these bottles means that the beverage will be consumed at multiple times with the bottle being sealed and stored in between times of consumption. Straw


532


is designed to present itself to the consumer when cap


530


has been removed. To do this, float


544


urges straw


532


through neck region


528


. Float


544


is able to urge straw


532


upward because it is initially located below the surface level of a full container


510


. When a portion of the liquid within container


510


is consumed and the consumer wishes to store container


510


, the consumer pushes straw


532


into container


510


and reveals neck region


528


with cap


530


. At this time, it is likely that float


544


will not be located below the surface level of the liquid remaining in container


510


. Thus, when cap


530


is again removed, straw


532


will not present itself to the consumer because float


544


does not have a buoyant force since it is sitting in air, not liquid.




Container


510


provides a solution to the above problem by locating a plurality of indicia or dimples


560


on wall


512


at various heights along wall


512


. Straw


532


is also provided with a plurality of indicia or dimples


562


at various heights along the length of straw


532


. Each indicia or dimple


560


on wall


512


in unique and corresponds to a unique indicia or dimple


562


on straw


532


. AS shown in

FIG. 13

, indicia


560


and


562


are shown as a single mark, a double mark and a triple mark. It is to be understood that any unique indicia or marking can be used. Thus, when the fluid level in the bottle is at the first indicia or dimple, the consumer, before pushing straw


530


into container


510


, relocates float


544


at the first indicia or dimple on straw


532


. This new location of float


544


will ensure that float


544


will be submerged in liquid and thus will have the buoyancy force needed to present straw


532


to the consumer during subsequent openings of cap


530


. The same process is involved when the fluid level in container


510


is at the second level and when it is at the third level with float


544


being located at the second level and the third level, respectively.




While this fluid level/float matching concept has been described using container


510


and straw


532


shown in

FIG. 13

, it is to be understood that this concept can be incorporated into any of the embodiments described above.
