Abstract
A reclosable fitment for a paperboard package having rear intrusion, anti-finger intrusion protection, and a raised spout to more naturally and directly allow the liquid within the container to be dispensed. The present invention provides a two piece fitment or closure having a base which is adapted to be attached about a scored area on a paperboard package. A lever is pivotally attached to the base and includes a rear portion which is adapted to open the scored area at a rear portion thereof. The rear portion is forced downwardly into the container by lifting upwardly on the forward portion of the lever. The forward portion of the lever has a built-in pouring spout which when placed into the open position forms a natural spout elevated away from the base to allow the liquid to more naturally and accurately be directed away from the package. A cover can be pivotally attached to the base to protect the lever from contaminates, and to automatically open the package upon lifting the cover away from the base.
Description




FIELD OF THE INVENTION




The present invention generally relates to containers for liquid, and more particularly relates to closures or fitments for such containers.




BACKGROUND OF THE INVENTION




Many goods today are sold in paperboard packages, wherein the paperboard is folded into a box like configuration, and provided with a non-porous lining to prevent leakage of the liquid from the package. A common example is provided in the form of the currently popular juice boxes wherein orange juice and the like can be provided in the package in a portable and easily accessible manner. In addition, many types of condiments and sauces can be provided in such packages and are particularly popular in foreign countries, and restaurant and cafeteria facilities wherein the goods are not sold through retail outlets.




With most such paperboard packages, a closure or fitment, typically plastic, is attached to the package about a scored or perforated area in the paperboard. The fitment is provided to allow a user to easily open the package and allow the contents of the package to be poured therefrom. Commonly, the fitment is provided with a lever arm which is hinged to a base of the closure and which can be downwardly depressed into the package. Such packages can often lead to finger intrusion which can contaminate the contents of the package, and result in an unsanitary mess to the consumer. Recent closure and fitment designs therefore have been directed to providing a mechanism by which the package can be opened, but limits finger intrusion. Currently pending U.S. Provisional Patent Application Nos. 60/073,897, and 60/074,882, which are now abandoned and are directed to such apparatus, the disclosures of which are expressly incorporated by reference herein.




In addition to providing a mechanism by which the package can be opened, such closures or fitments typically have a built-in pouring spout raised slightly above the surface or edge of the container to direct the liquid as it is being dispensed through the opening created by the fitment. However, such pour spouts are typically provided relatively close to the edge of the container and do not direct the liquid away from the package in a well defined, controllable, manner. Additionally, the tongue of the fitment which opens the package can interfere with the dispensing of liquid as the package is tilted forward and the liquid acts against the underside of the closure tongue.




Simply providing a raised spout on the outer surface of the container is not a viable solution in that it would add additional expense to the package and be susceptible to breakage of the spout from the container during shipping and handling. Furthermore, such packages typically require some form of tamper evidence to ensure that by the time the container is actually purchased and ready for use by the consumer, the consumer is provided with a level of security that the contents of the package have not been altered.




Moreover, with many known fitments, in addition to a base having a lever which is pivotally attached thereto, a cover is also pivotally attached to the base. The cover initially covers the base and lever and must be hinged away from the base to gain access to the lever. The process of opening packages using such a fitment entails at least two steps, wherein as a first step, the cover is hinged away from the base, and as a second step, the user downwardly depresses the lever into the package. After use, the lever remains within the package, and the cover is hinged back to the base for closure purposes. Still further types of closures require three steps wherein the cover and a built-in pour spout are provided in the same plane as the lever when the fitment is initially provided. The cover and built-in pouring spout are initially pivoted about a base which causes the lever to penetrate the package. After approximately 180 degrees of rotation, the pour spout attaches to a front portion of the base to lock it in place. The cover is then pivoted back away from the pour spout to open the fitment.




While such types of fitments are functional, the multiple steps involved are time consuming, and are often viewed as a nuisance or cumbersome to the user. It would therefore be advantageous if a package fitment were to be provided wherein the cover can be pivoted away from the base and the package can be opened in one simple step.




SUMMARY OF THE INVENTION




It is therefore an objective of the present invention to provide a fitment for paperboard package wherein a cover can be pivoted away from the base of the fitment and the package can be opened in one step.




It is another objective of the present invention to provide a fitment for a paperboard package which has rear intrusion and a built-in frontal pour spout.




It is another objective of the present invention to provide such a fitment with improved finger intrusion protection.




It is another objective of the present invention to provide a fitment for a paperboard package having a pour spout which is substantially raised above the edge of the container to provide a more natural and directed pouring action.




It is still a further object of the present invention to provide a fitment for a paperboard package having a mechanism to protect the fitment from contaminate intrusion, as well as serving as tamper evidence.




It is still another object of the present invention to provide a mechanism to seal the pour spout against the base of the fitment to avoid dual stream output.




It is yet another object of the present invention to positively maintain the pour spout lever in the open position to prevent the liquid from forcing the fitment into a closed position when acting against an underside of the pour spout lever.




It is still another object of the present invention to provide a fitment wherein the user directs an upward force against the fitment, away from the package, to open the package and thereby avoids finger intrusion.




It is a feature of the present invention to provide, in a preferred embodiment, a closure for a container of dispensable fluid including a base and a lever pivotally attached to the base. The base is adapted to be secured adjacent a pouring lip of a container and has an opening adapted to be disposed proximate a scored area of the container. The lever includes a puncturing end and a pour spout end, with the spout end being proximate the container pouring lip, and the lever being adapted to move between a storage position wherein the lever is substantially parallel to the base, and a pouring position wherein the lever is orthogonal to the base. The spout end is displaced away from the container and the puncturing end is displaced into the container through the scored area when the lever is in the pouring position.




It is another feature of the present invention to provide a closure having a base, a lever pivotally attached to the base, and a cover pivotally attached to the base. The cover serves to protect the closure from contaminate intrusion, and automatically open the closure upon pivotal motion of the cover.




It is another feature of the present invention to provide a closure having a base, a lever pivotally attached to the base, and a cover pivotally attached to the base, wherein the lever extends past the front of the cover. The force used by the user to open the package therefore is directed against the bottom side of the lever which in turn separates the cover from the base. The user then continues to direct force against the lever until such time that the lever locks in place to allow the user to continue to apply force against the cover to move it to its fully opened position.




These and other objects and features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

While the invention is susceptible of various modifications and alternative constructions, certain illustrative embodiments thereof have been shown in the drawings and will be described below in detail. It should be understood, however, that there is no intention to limit the invention to the specific forms disclosed, but on the contrary, the intention is to cover all modifications, alternative constructions and equivalents falling within the spirit and scope of the invention as defined by the appended claims.




DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring now to the drawings, and with particular reference to

FIG. 1

, a preferred embodiment of the present invention is generally depicted as fitment


20


. Fitment


20


is secured to paperboard package


22


over a scored or perforated area of the paperboard package (not shown). By way of overview, it can be seen by one of ordinary skill in the art that fitment


20


includes a base


24


which is adapted to be adhesively bonded to paperboard package


22


about flange


26


, and a lever


28


which is pivotally attached to base


24


. Upon lever


28


being pivoted, rear portion


30


of lever


28


is depressed into package


22


through the scored area, (not shown) while forward portion


32


is elevated away from the base and is orthogonal thereto, as best shown in the open position of FIG.


2


. While in the preferred embodiment, lever


28


is disposed relative to base


24


about an angle of approximately 60 degrees in the open position, it is to be understood that multiple angular dispositions can be achieved in the open position.




In more specific detail, fitment


20


is also shown in

FIGS. 3 and 4

, in the closed and open positions, respectively. Base


24


includes in addition to flange


26


, raised wall


34


having open end


36


, and opposing side walls


38


,


38


′. Side walls


38


,


38


′ include sockets


40


,


40


′ (see

FIG. 7

) which are adapted to receive arms


42


,


42


′ of lever


28


, as will be discussed in further detail herein. In the preferred embodiment of the present invention, base


24


is manufactured from a single molded piece of plastic, but the invention is intended to cover multiple materials and mechanisms for manufacturing base


24


.




Lever


28


, as indicated above, includes a rear portion


30


and a forward portion


32


. As can readily be seen from the figures, particularly

FIGS. 5 and 6

, rear portion


30


is substantially lower than forward portion


32


and includes a transition zone


44


. It is forward portion


32


which serves as the pour spout for the fitment


20


to more naturally and orderly direct the contents of the container through fitment


20


. Forward portion


32


includes channel walls


46


raised above forward portion


32


. Proximate transition zone


44


, arms


42


,


42


′ laterally extend to sufficiently engage sockets


40


,


40


′ of the base


24


and thereby allow lever


28


to pivot relative to base


24


when moving from the closed position shown in

FIG. 3

, to the open position shown in FIG.


4


. While not depicted, it is to be understood that the underside


48


of rear portion


30


could include a number of intrusion enhancing devices to more easily facilitate puncturing and slicing through the perforated or scored area of the paperboard package


22


.




As shown best in

FIGS. 6 and 9

, base


24


includes a canted surface


50


which cooperates with underside


48


of lever


28


to effectively seal lever


28


to base


24


in the open position shown in FIG.


8


. In other words, liquid from container


22


cannot pass between lever


28


and base


24


at nexus or seal


52


due to the sealing connection between base


24


and lever


28


. Rather, the liquid from the container


22


must pass entirely through opening


54


(see

FIG. 8

) provided in base


24


defined by raised wall


34


.




In order to substantially prevent lever


28


from being closed by the liquid acting against underside


48


during pouring, the present invention could include a positive stopping mechanism on lever


28


. For example, sockets and arms


42


could be hexagonally shaped to thereby allow lever


28


to move in discrete motions and only when sufficient power is applied. Other forms of stopping mechanisms including clips, detents, locking grooves and the like could also be employed to thereby improve the pourability of the present invention.




In addition,

FIG. 9

dramatically depicts the improved pour spout location of the present invention. As opposed to prior art devices which provide a relatively low pour spout, if any pour spout is provided at all, the present invention elevates pour spout


32


substantially above base


24


and away from package


22


. This allows the liquid to follow a more natural flow from package


22


, and due to channel walls


46


on pour spout


32


, the liquid can be more accurately directed out of the package


22


. This is accomplished while at the same time providing a fitment


20


which can be reclosed into the position shown in

FIGS. 1 and 6

wherein the fitment


20


occupies relatively little space and is substantially insusceptible to breakage during shipping and handling. Moreover, since the lifting force for opening package


22


using fitment


20


is entirely directed against underside


56


of pour spout


32


, when an operator wishes to open package


22


, the fingers of the operator are not inclined to enter package


22


and contaminate the fluid contained therein. In other words, there is no need for the operator to direct force downwardly into package


22


as with many prior art designs in that the majority of the force needed for opening will be directed away from package


22


.




In second preferred embodiment of the present invention shown in

FIGS. 10-20

, fitment


20




a


is provided with a cover


58




a


which is adapted to pivot relative to base


24




a


. As will be described herein, cover


58




a


serves many functions which provide advantages including, but not limited to, preventing the intrusion of contaminates into package


22




a


and serving as tamper evidence to the user of the package. In addition, through the unique features of the preferred embodiment, cover


58




a


can automatically open package


22




a


by lifting upward on pour spout


32




a


as cover


58




a


is hinged about base


24




a


. This action virtually eliminates finger intrusion into package


22




a.






Referring now to

FIG. 13

, the second preferred embodiment is shown in perspective as being quite similar to the embodiments shown in FIGS.


1


-


9


.However, base


24




a


includes rear wall


60




a


which defines pivot


62




a


between cover


58




a


and base


24




a


. Other than rear wall


60




a


and pivot


62




a


, base


24




a


and lever


28




a


are substantially the same as the first embodiment. However, raised wall


34




a


of base


24




a


does include outwardly extending lip


64




a


(see

FIG. 14

) which interacts with sealing rim


66




a


provided on underside


68




a


of cover


58




a


. Sealing rim


66




a


is dimensioned to be slightly larger than lip


64




a


such that in the closed position of

FIG. 13

, cover


58




a


substantially seals against raised wall


34




a


and prevents the contents of package


24




a


from being dispensed.




Cover


58




a


also includes an oversized, downwardly depending, actuator


70




a


proximate front


72




a


of cover


58




a


. It is actuator


70




a


which cooperates with pour spout


32




a


to automatically open fitment


20




a


upon fitment


20




a


moving between the positions shown respectively in

FIGS. 10

,


11


, and


12


.




While there are a number mechanisms for accomplishing this interaction between actuator


70




a


and the pour spout of lever


28




a


, in the second preferred embodiment, as best shown in

FIG. 16

, actuator


70




a


includes inwardly extending ridge


74




a


which snaps over pour spout


32




a


in the closed position, and resides below downwardly extending detent


76




a


of pour spout


32




a


. Therefore upon cover


58




a


being moved from the fully closed position shown in

FIG. 10

, to the partially opened position shown in

FIG. 11

, actuator


70




a


and corresponding ridge


74




a


pull against detent


76




a


and pour spout


32




a


to lift pour spout


32




a


upwardly and force rear portion


30




a


into the container


22




a


, through the scored area, as lever


28




a


pivots about transition zone


44




a


. Upon reaching the fully open position shown in

FIG. 12

, further motion of cover


58




a


causes it to separate from pour spout


32




a


by having ridge


74




a


elastically deform away from detent


76




a


. Cover


58




a


can therefore attain the fully opened position shown in

FIG. 12

wherein the contents of package


22




a


can freely exit the container through fitment


20




a


opening


54




a


shown in FIG.


17


.




In another embodiment of the present invention, actuator


70




a


could be physically attached to pour spout


32




a


when initially purchased, and be provided with a frangible portion which is sufficiently strong to allow lever


28




a


to press through paperboard package


22




a


, but upon further force being exerted will break and thereby allow cover


58




a


to fully detach from pour spout


32




a


. Such a frangible portion could thereby serve as tamper evidence in that the user could easily identify an already opened container if the frangible portion were to be broken.




A third preferred embodiment of the present invention is shown in

FIGS. 20-32

. As shown therein, fitment


20




b


is adapted to be attached to paperboard package


22




b


and includes a base


24




b


, a lever


28




b


(see FIG.


24


), and a cover


58




b


. However, lever


28




b


includes extended tongue


78




b


which extends past front


82




b


of cover


58




b


. Therefore when a user attempts to open the fitment, as best shown in

FIG. 22

, the lifting force is applied against underside


80




b


of tongue


78




b


, and not against cover


58




b


. As fitment


20




b


continues to be opened the pulling force is continued to be directed against underside


80




b


as best shown in

FIG. 23

, until such time that the lever


28




b


reaches a locked position shown in FIG.


24


. As shown in

FIGS. 24 and 30

, lever


28




b


reaches a locked position wherein underside


48




b


of lever


28




b


engages canted surface


50




b


of base


24




b


and cannot pivot further. The respective pivot points of lever


28




b


and cover


58




b


, as well as the lengths of cover


58




b


and tongue


78




b


, are dimensioned such that at the point where lever


28




b


engages canted surface


50




b


, extended lip


82




b


of cover


58




b


becomes exposed and the operator can then direct lifting force against lip


82




b


to place fitment


20




b


in the fully open position shown in

FIGS. 25 and 31

. In other words, at about 60 degrees of rotation, lever


28




b


becomes locked, and lip


82




b


overcomes tongue


78




b


. Further rotation by the user is then directed only against lip


82




b


. One benefit to this embodiment over that shown in the second preferred embodiment is that the consumer need not rely on the snap between the cover and the lever to achieve tearing into the package, but rather the force for opening the package can be fully derived from the lifting force of the user imparted directly against the underside of the lever.




A fourth preferred embodiment is shown in

FIGS. 32-35

which is identical to the third embodiment except that it additionally includes tamper evidence indicators. As shown in

FIGS. 34 and 35

, base


24




c


includes a tamper indicator


84




c


connected to base


24




c


at platform


86




c


. Tamper indicator


84




c


includes a deformable head


88




c


having upper portion


90




c


and lower portion


92




c


connected at hinge


94




c


. In the fully closed position shown in

FIG. 34

, upper portion


90




c


is connected to cover


58




c


along a frangible portion


96




c


. When cover


58




c


is move slightly away from base


24




c


, the frangible portion


96




c


is broken which allows the upper portion


90




c


of the deformable head


88




c


to plastically deform into an upright position shown in FIG.


35


. This provides the user with an indication that the fitment


20




c


has already been opened or in other words tampered with.




This embodiment also includes a hold down snap. As shown in

FIGS. 32 and 33

, hold down snap


98




c


includes lower clip


100




c


which is adapted to elastically deform as it moves through locking aperture


102




c


of base


24


. In other words, when cover


58




c


is in the fully closed position shown in

FIG. 32

, lower clip


100




c


is provided through locking aperture


102




c


and is biased outwardly to engage clip


100




c


against the underside of base


24




c


. However when cover


58




c


is moved away from base


24




c


, locking clip


100




c


is able to elastically deform inward to allow passage of clip


100




c


through aperture


102




c


. Hold down snap


98




c


accomplishes, among other things, the function of ensuring that both sides of fitment


20




c


remain closed and that the fitment


20




c


cannot be tampered with by prying the side of cover


58




c


opposite tamper indicator


84




c


away from base


24




c


and thereby tampering with the contents of package


22




c


. Since tamper indicator


84




c


is provided on a side of fitment


20




c


, hold down snap


98




c


is provided on the opposite side to ensure that the assembly stays closed and none of the components of the fitment


20




c


or the contents of container


22




c


can be altered.




A fifth preferred embodiment is shown in

FIGS. 36-39

. The fifth preferred embodiment incorporates the hold-down snap


98




d


of the fourth preferred embodiment, but employs different mechanisms for lifting the lever


28




d


forward portion


32




d


away from base


24




d


. More specifically, it can be seen in

FIG. 38

that cover


58




d


includes downwardly depending arms


104




d


having inwardly directed ridges


106




d


. In so doing, ridges


106




d


and arms


104




d


cooperate to define pin slots


108




d


. In the closed position, pin slots


108




d


are adapted to receive pins


110




d


which laterally extend from forward portion


32




d


of lever


28




d


. Therefore, when an operator attempts to open fitment

From the foregoing it can therefore be seen to one of ordinary skill in the art that the present invention provides a two piece fitment for a paperboard package with improved pourability, enhanced anti-finger intrusion protection, positive tamper evidence, and a mechanism for automatically opening the package upon movement of an outer cover. The improved pourability is accomplished by, among other things, providing a pour spout which can be moved into an operative position wherein it is substantially raised above the surface of the base, and includes channel walls on the pour spout to more accurately direct the contents out of the package. The present invention provides a mechanism wherein the force required for opening the package can be directed entirely against the underside of the pour spout and thereby away from the package, to thereby substantially eliminate the possibility of finger intrusion into the container. This finger intrusion protection is even more evident in an alternative embodiment wherein a cover is also pivotally attached to the base and temporarily attached to the pour spout of the lever. Therefore, when the cover is pivoted away from the base, it automatically pulls the pour spout with it, and causes the rearward portion of the lever to pass through, and thereby open, the package. The cover then breaks away from the pour spout leaving the lever in the fully operable position, and the cover fully hinged away from the base.



Claims

The reclosable package fitment of claim 7 wherein the base includes a canted surface portion transverse to the opening, the canted surface acting as a physical stop and a seal between an underside of the lever pour spout end and canted surface such that pivotal movement of the lever to the open position is limited to an acute angle to a plane coincident with an interface of the base and the container.
  • 9. The reclosable package fitment of claim 8 where the acute angle is approximately 60 degrees to thereby allow the lever pour spout end to extend upward and away from the base such that when a container provided with the fitment is tilted to pour contents from the container, the contents pass through the opening in the base along the pour spout channel in a continuous stream away from the container.
  • 10. The reclosable package fitment of claim 9 wherein the base includes a tamper evident element that cooperates with a frangible portion of the cover so that frangible portion of the cover is broken when the cover is opened.
  • 11. The reclosable package fitment of claim 5 wherein the lever extends past a front edge of the cover when the fitment is closed to facilitate access to the lever and thus the opening of the container.
  • 12. The reclosable fitment of claim 5 wherein the base includes a recessed area proximate the pour spout end of the lever and the cover.
  • 13. The reclosable package fitment of claim 5 wherein the pivotable attachment between the base and lever comprises pivot arms fitted within sockets to pivotally attach the lever to the base.
  • 14. A reclosable package fitment comprising:a base adapted to be attached to a container, the base including an opening therethrough; a lever recessed within the opening and pivotally attached to the base to pivot between a closed position and an open position, the lever is pivotally attached to the base intermediate a lever pour spout end and a lever puncturing end; a cover attached to the base, the cover being hinged to the base independently of the lever; the cover and lever pour spout end cooperating to move in unison upwardly from the base to thereby cause the lever pour spout to be raised above the base to an open position and the lever to pivot relative to the base which causes the lever puncturing end to engage and puncture the container to thereby open the container and cause the cover to hinge away from the base.
  • 15. The reclosable package fitment of claim 14 wherein the lever pour spout end has a channel shaped cross-section.
  • 16. The reclosable package fitment of claim 15 wherein the cover includes a lip that mechanically cooperates with the lever pour spout end to cause the pour spout end to move and pivot when a lifting force is applied to the cover in a region adjacent to the lip.
