Description




BACKGROUND OF THE INVENTION




1. Technical Field




The subject invention is generally directed to a closure for a container. More particularly, the invention relates to threaded closures for containers. Specifically, the invention relates to a closure for providing access to the contents of a container without the necessity of completely removing the entire closure and thereby subjecting the closure to loss or damage.




2. Background Information




Various containers for storing and transporting fluids such as water have been known and used for thousands of years. Prior to modern times, water containers were a necessity since homes and businesses did not have running water and therefore containers were needed to transport water from the local well to each house or business.




Many closures for containers have been developed including lids, corks, snap-ons, and screw caps. Since man's discovery that fluids could be stored within containers for later use, new and better means for closing, sealing, or otherwise controlling fluid flow into and out of the container have been sought.




More recently, i.e., over approximately the past one hundred years, a phenomenal growth in the distribution of bottled beverages has occurred. The storage of beverages such as milk, water, juices, carbonated beverages, iced tea, and alcoholic beverages in containers such as cartons, bottles, flasks or jugs made from paper, plastic, or glass has flourished. Specifically, these various containers include paper milk cartons, 12 and 16 glass bottles, 2 liter plastic bottles, and other such containers.




Bottled beverages typically come in either plastic or glass bottles with metal or plastic closures sealing the beverage therein until the time for consumption. These containers typically include a narrowing neck with a fluid access opening therein. A number of closures have been used to cover this fluid access opening including metal lids requiring a bottle opener to remove, twist off metal lids, snap on-off plastic caps, screw on-off plastic caps, and pull up and push down type caps. These caps all serve to provide access to the fluid contained within the container. The closure is preferably reusable in that it may be removed from and replaced onto the container thereby allowing only a portion of the fluid contained within the container to be used at a given sitting.




The need for closure of these containers is historically based upon a number of concerns including spillage, spoilage, evaporation, and contamination of the fluid contained within the container. More recent designs continue to take into account these historical needs as well as today's desired qualities such as ease and speed of use, and retention of carbonation.




However, one disadvantage of these closures is the requirement that the closure be completely removed to gain access to the container. Complete removal of the closure creates a risk that the closure will be misplaced or dropped.




SUMMARY OF THE INVENTION




Objectives of the invention include providing a container closure for providing access to the fluid contents of a container without the necessity of completely removing the entire closure and thereby subjecting the closure to loss or damage, and the fluid contents of the container to spillage, spoilage, evaporation, and contamination.




A further objective of the invention is to provide a two part closure connected together by a flexible hinge.




Still a further objective of the invention includes providing a closure which is only partially removed to allow access to the fluid within a container.




Another objective of the invention is to provide a closure which, when fully tightened down, seals off the fluid access opening thereby assuring continued quality of the beverage within the container.




A still further objective of the invention is to provide a closure with a position indicator to indicate that sufficient twisting has occurred to disengage the cap portion from the container while the sleeve portion continues to engage the container.




Yet a further objective of the invention is to provide a position indicator which also acts as a catch that tends to restrict rotation of the closure with references to the threaded nozzle.




Yet another objective is to provide a closure which is of simple construction, which achieves the stated objectives in a simple, effective and inexpensive manner, and which solves problems and satisfies needs existing in the art.




These and other objectives and advantages are obtained by the improved closure of the present invention that is securable to a nozzle of a container, the nozzle having a plurality of threads formed thereon, the general nature of which may be stated as including a first portion having a plurality of internal threads formed thereon, a second portion having a plurality of internal threads formed thereon, a flexible hinge connecting the first portion to the second portion, and the flexible hinge including at least a portion of the threads formed on the first portion and including at least a portion of the threads formed on the second portion, the hinge being adapted to selectively threadably engage the threads formed on the nozzle.




Other objectives and advantages are obtained from the closure and container assembly of the present invention, the general nature of which may be stated as including a container having a neck with an access port formed therein, the neck having a plurality of external threads formed thereon, a fluid access port closure having a cap portion and a sleeve portion separated by a substantially circumferential gap and connected by a hinge, the cap and sleeve portions each having threads to operatively engage the externally threaded neck thereby defining a fully threaded position where the threads of both the cap and the sleeve portions at least minimally engage the externally threaded neck, a partially threaded position where only the threads of the sleeve portion at least minimally engage the threaded neck, and a removed position where none of the threads engage any of the threaded neck, and the hinge including at least a portion of the threads on the cap portion and including at least a portion of the threads on the sleeve portion, the hinge being selectively threadable with the external threads of the neck.

DESCRIPTION OF THE PREFERRED EMBODIMENTS




The improved bottle closure assembly is indicated generally at A in its intended environment as a closure for a container B and is shown generally in

FIGS. 1 and 2

.




As illustrated in

FIGS. 1 and 2

, the container B is a bottle


20


comprising a main body


22


, a neck


24


, and a nozzle


26


. The main body


22


is the fluid storage cavity. The neck


24


is an inverted funnel-shaped or dome-shaped portion connecting the main body


22


to the nozzle


26


. The nozzle


26


includes an externally threaded cylindrical portion


28


.




As is shown in

FIG. 2

, the top of the nozzle


26


has a hole


30


that functions as a fluid access port through which all fluid enters and exits the container B. Around the hole


30


is a lip or edge


32


upon which the closure A seats or rests when fully threaded onto the nozzle


26


. The combination of the threaded interaction between the closure A and the nozzle


26


, and the seating or resting of the closure A on the lip


32


results in a seal for preventing leaking of the fluid from within the container. Nozzle


26


also includes an unthreaded portion


34


and a flange


36


. Bottle


20


is made from any material, such as glass without departing from the spirit of the present invention. In the preferred embodiment, the bottle is a plastic extrusion blow molded container such as a 2-liter bottle.




The closure assembly A, as is illustrated in

FIGS. 1-4

comprises a sleeve portion


38


and a cap portion


40


pivotally connected together by a hinge


42


. The cap portion


40


includes a closed top


44


against which the top edge or lip


32


of the nozzle


26


abuts when the closure A is fully threaded onto the nozzle


26


.




In accordance with one of the main features of the present invention, the cap portion


40


is defined by a cylindrical side wall


46


and two circular ends. One end is open and has a circular face


48


of approximately the same thickness as the cylindrical side wall


46


. The other end is closed by circular top


44


. The cylindrical side wall


46


extends transversely away from the circular top


44


. The cylindrical side wall


46


and circular top


44


define a cavity in the cap portion


40


. The inner surface of the cylindrical side wall


46


in the cavity has circumferential threads


50


thereon that are complimentary to the external threads on the nozzle


26


thereby allowing the cap portion


40


to be threaded completely onto the externally threaded portion


28


of the nozzle


26


.




The sleeve portion


38


is defined by a cylindrical side wall


52


with a top and a bottom open end. Each open end has a circular face


54


A and


54


B, respectively. The sleeve portion


38


is shaped and functions as a cylindrical extension of the cap portion


40


. The sleeve portion


38


is also axially alignable with the cap portion


40


when the cap portion is closed against the sleeve portion. The sleeve portion


38


is of the same cross-sectional size and shape as the cap portion


40


. The cylindrical side wall


52


defines a through-bore in the sleeve portion


38


. The inner surface of the cylindrical side wall


52


in the through-bore has circumferential threads


56


thereon that are complimentary to the external threads on the nozzle


26


. The circumferential threads


56


are also alignable with the circumferential threads


50


of the cap portion


40


so that when the cap portion


40


is closed against the sleeve portion


38


the external threads on the nozzle


26


can mate with both threads


50


and


56


thereby allowing the cap portion


40


and the sleeve portion


38


to be threaded completely onto the externally threaded portion


28


of the nozzle


26


.




The external arcuate surface of both the sleeve portion


38


and the cap portion


40


is ribbed with longitudinal ribs


58


. These ribs provide a better surface for gripping when tightening or loosening the cap portion


40


from the nozzle


26


.




The closure A is made from a polymeric compound, although it can be made from any material without departing from the spirit of the present invention. In the preferred embodiment, the closure A is a molded plastic closure. The closure can be molded as a three part (cap, hinge, and sleeve) closure, or it can be molded as a one part cap and partially cross-sectionally cut thereby forming a cap and sleeve portion with a connecting hinge.




The use of the closure A and the container B involves three general closure positions or ranges with reference to the nozzle


26


: a fully or substantially fully threaded position, a partially threaded position, and a completely unthreaded position. The results of these various positions are a sealed container, a fluid accessible container where the cap portion is movable from a closed to an open position, and a completely open (uncapped) container, respectively.




The closure A is shown in

FIG. 1

in a fully threaded position where the lip


32


(hidden within the cap portion) abuts or nearly abuts the top


44


. When the closure A is in this fully threaded position, the cap portion


40


is fixed to the closure


26


based upon the interengagement of the internal threads of the cap with the external threads of the nozzle


26


. The result is that the cap portion is not pivotable about the hinge


42


thereby prohibiting access to the fluid within the container B via the hole


30


.




The closure A is shown in

FIG. 2

in a partially threaded position where only the sleeve portion


38


is threaded onto the threaded nozzle


26


and the threads of the cap portion no longer engage the nozzle


26


. The result of this partial threading is that the cap portion


40


is pivotable about the hinge


42


.

FIG. 2

shows the cap portion


40


of the closure A after it has been pivoted to an open position from the closed position. This open position allows access to the fluid within the container B for removal (or addition) of fluid such as by pouring into a glass.




Although not shown in

FIG. 1

or


2


, the closure A is also completely removable from the nozzle


26


. This occurs by completely unthreading the closure A from the nozzle


26


. This allows reuse of the closure A on another container after the fluids within container B have been fully depleted.





FIGS. 5-13

disclose an alternative embodiment for the container and the closure. Closure A′ and container B′ are substantially identical to closure A and container B except that both closure A′ and container B′ include one or more protuberances that extend into the interaction area where the threads


50


and


56


, and corresponding adjacent surfaces of the sleeve portion


38


and the cap portion


40


interact.




In the second embodiment, the nozzle


26


as is shown in

FIG. 7

includes a pair of protuberances


60


A and


60


B with a small gap


62


therebetween. Each of these protuberances


60


A and


60


B are small nubs protruding outward from the external surface of the nozzle


26


. Preferably, the protuberances


60


A and


60


B protrude outward from the unthreaded portion


34


of the nozzle


26


.




In accordance with one of the main features of the second embodiment, the closure A′ has a single protuberance


64


. This protuberance may be located at any position on the inside facing of the sleeve portion


38


or the cap portion


40


, although this protuberance must be located in a position on this inside facing that corresponds at the proper cap release time with the location of the pair of protuberances on the nozzle


26


. Typically, the protuberance


64


is located near the circular face


54


A thereby corresponding to the pair of protuberances


60


A and


60


B which preferably protrude from the unthreaded portion


34


. It is most preferred that protuberance


64


be located near circular face


54


A inasmuch as the external arcuate surface of sleeve


38


extends outwardly slightly at that point (

FIGS. 11-13

) such that side wall


52


is thicker adjacent protuberance


64


than adjacent top


44


, thus strengthening the lowermost region of sleeve portion


38


and providing enhanced support for protuberance


64


that extends inwardly therefrom.




All of the protuberances


60


A,


60


B, and


64


are arcuate in shape, such as rounded or conical, thereby providing a smooth, curving surface with a central peak for a corresponding protuberance interactively positioned in approximately tangential relation on an adjacent rotating surface to ride up and over with minimal yet accountable resistance. The result of this curving surface and the interactive positioning which provides some resistance is that the closure A′ is freely rotatable on the threaded nozzle


26


until the protuberance


64


on the closure meets one of the protuberances


60


A and


60


B on the nozzle whereby additional twisting action is required to overcome the resistance of the two interacting protuberances


64


and


60


A, or


64


and


60


B. This additional twisting overcomes the resistance and pops the protuberance


64


up and over one of the protuberances


60


A or


60


B and positions protuberance


64


in the gap


62


. Any continued twisting will overcome the second protuberance and allow the closure to completely be removed from the nozzle


26


.




Specifically, the pair of protuberances


60


A and


60


B act as a locking area whereby when the single protuberance


64


of the closure is in the gap


62


between the protuberances


60


A and


60


B, the closure is restricted from free rotation due to the confinement of the single protuberance


64


between the close proximity protuberances


60


A and


60


B.





FIGS. 9 and 11

show the closure A′-nozzle


26


interaction when the single protuberance


64


of the closure is in a first range of positions described with respect to the first embodiment of the invention (i.e., either fully threaded or partially threaded sufficiently that the cap portion is threaded onto the nozzle, and thus the single protuberance is not confined between the pair of protuberances


60


A and


60


B). The closure A′ is freely rotatable about the threads on nozzle


26


within this first range of positions which specifically extends from a first cap-locked position where the closure has sealed hole


30


in the top of the container B′ and the closure is fully threaded onto nozzle


26


, to a second cap-locked position where the single protuberance


64


of the closure is adjacent protuberance


60


A of the pair of protuberances


60


A and


60


B, and just outside the gap


62


in between the pair of protuberances


60


A and


60


B. As specifically shown in

FIG. 11

, the internal threads of both the cap portion and the sleeve portion engage the threads of nozzle


26


.




In contrast,

FIGS. 10 and 12

show the closure A′-nozzle


26


interaction when the single protuberance


64


of the closure is confined in the gap


62


between the pair of protuberances


60


A and


60


B. The closure A′ is confined in this gap absent additional twisting action to overcome the resistance of the one of the two interacting protuberances


64


and


60


A, or


64


and


60


B and escape the gap.




The purpose of snapping the single protuberance


64


in between the pair of protuberances


60


A and


60


B is to indicate that the closure is properly positioned for the opening of the container B′. Specifically, the indication of proper positioning signifies that the cap portion


40


is properly positioned to be pivoted about the hinge


42


and away from the sleeve portion


40


to provide access to the hole


30


in the top of the container. In contrast, if the protuberance


64


is not in the gap, but still in the first range, i.e., not properly aligned in between the pair of protuberances, then the cap portion


38


cannot be removed from the nozzle


26


because the threads of each are at least partially still engaged.




The closure A′ and the container B′ may also be positioned in a second range of positions. If an additional twisting action is supplied to overcome the resistance of the pair of protuberances


60


A and


60


B, then the single protuberance snaps out the gap and into a second range. The closure A′ is freely rotatable about the threads on nozzle


26


within this second range of positions which extends from a first cap-unlocked position where the single protuberance


64


of the closure is adjacent protuberance


60


B of the pair of protuberances


60


A and


60


B and just outside the gap


62


in between the pair of protuberances


60


A and


60


B, to a second cap-unlocked position where the closure A′ is completely removable from the nozzle


26


.




The closure A′ may be threaded back onto the nozzle


26


in a manner similar but reversed of the above described removal process. The closure A′ is reusable and therefore may be removed from and rethreaded onto a container over and over.




As is best shown in

FIG. 11

, hinge


42


traverses between one of threads formed on cap portion


40


and one of threads


56


formed on sleeve portion


38


. Hinge


42


thus is a threadable member whereby external threads


28


of nozzle portion


26


are threadable directly over and threadingly engage hinge


42


. In this regard, and as is best shown in

FIG. 13

, the threaded engagement of the thread


56


of hinge


42


adjacent sleeve portion


38


with external threads


28


of nozzle portion


26


provides an anchor that retains sleeve portion


38


on nozzle


26


when cap portion


40


is rotated upwardly away from nozzle


26


about hinge


42


.




Furthermore, as is best shown in

FIG. 12

, the lowermost thread


50


of cap portion


40


is preferably disposed adjacent circular face


48


at a point diametrically opposed to hinge


42


. In this regard, the aforementioned thread


50


abuts nozzle portion


26


when cap portion


40


is aligned with sleeve portion


38


as is shown in FIG.


12


. The engagement of the aforementioned thread


50


with nozzle portion


26


provides an additional level of security to ensure that cap portion


40


does not rotate upwardly (

FIG. 13

) until the user affirmatively pulls thread


56


out of engagement with nozzle portion


26


, thus permitting cap portion


40


to be rotated upwardly.




In sum, the invention is a closure A or cap for a container B such as a bottle having external threads


28


on a nozzle portion


26


. The cap A includes a lower or sleeve portion


38


and an upper or cap portion


40


. The sleeve portion


38


and the cap portion


40


are hingedly connected at living hinge


42


. The sleeve portion


38


includes internal circumferential threads


56


on at least a portion of the cylindrical side wall


52


that are complementarily related to the threads


28


on the nozzle for retaining the sleeve portion to the nozzle. Similarly, the cap portion


40


includes internal circumferential threads


50


on the cylindrical side wall


46


for retaining the cap portion to the nozzle.




When the closure is rotated to the fully threaded position, i.e., fully tightened down on the nozzle, the threads


50


and


56


of the cap and sleeve portions


40


and


38


engage the threads


28


of the nozzle


26


to lock the cap portion


40


in a closed position. However, when the closure is rotated, the threads


50


within the cap portion


40


disengage from the threads


28


of the nozzle


26


such that the hinge


42


may be actuated to open the cap portion


40


thereby allowing access to the fluid within the container B.




The invention may also be embodied with protuberances or nubs


60


A and


60


B on the nozzle, and


64


on the sleeve portion, for restricting rotation (twisting) of the closure absent some additional force to overcome the resistance provided by the interaction of protuberance


64


with either protuberance


60


A or


60


B. This resistance indicates that the closure is properly positioned for the pivoting of the cap portion thereby provided access to the fluid within the container.




Accordingly, the improved bottle closure apparatus is simplified, provides an effective, safe, inexpensive, and efficient device which achieves all the enumerated objectives, provides for eliminating difficulties encountered with prior devices, and solves problems and obtains new results in the art.




In the foregoing description, certain terms have been used for brevity, clearness, and understanding; but no unnecessary limitations are to be implied therefrom beyond the requirement 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 invention is by way of example, and the scope of the invention is not limited to the exact details shown or described.




Having now described the features, discoveries, and principles of the invention, the manner in which the improved bottle closure apparatus is constructed and used, the characteristics of the construction, and the advantageous new and useful results obtained; the new and useful structures, devices, elements, arrangements, parts, and combinations are set forth in the appended claims.
