TECHNICAL FIELD




This invention relates to a system for dispensing product from a container. The invention is more particularly related to a system that facilitates removal of a product through either one of two different dispensing orifices.




BACKGROUND OF THE INVENTION AND TECHNICAL PROBLEMS POSED BY THE PRIOR ART




A variety of packages, including dispensing packages or containers, have been developed for particulate food products, such as herbs, spices, granular salt, etc., as well as other materials. Such containers typically have an open upper end on which is mounted a closure.




U.S. Pat. No. 5,975,368 discloses a type of dispensing closure for a dispensing container which has a body defining two relatively large side-by-side access apertures. A foraminous member defining a plurality of dispensing holes is hingedly mounted for being pivoted between (1) a first position over the two side-by-side access apertures, and (2) a second position away from the side-by-side access apertures. A lid is hinged to the body for pivoting between an open position and a closed position over the foraminous member when the foraminous member is over the side-by-side apertures in the closure body. In the closed position, the lid sealingly occludes the plurality of apertures in the foraminous member. When the lid is open, the foraminous member can be moved to either of two selected positions: (1) a full open position spaced away from the two side-by-side apertures in the closure body to permit access to the product through the two side-by-side apertures in the closure body, and (2) a closed position wherein the foraminous member is disposed over the two side-by-side apertures in the closure body to permit sprinkling of the container contents through the foraminous member apertures.




While the above-described container closure functions well when used in the applications for which it has been designed, it would be desirable to provide an improved dispensing system for containers providing certain operational advantages and accommodating certain design variations.




It would be particularly desirable to provide an improved dispensing structure have a body with a first dispensing aperture, a lid, and an intermediate member, wherein the intermediate member defines at least one smaller dispensing aperture and can be readily rotated together with a lid between open and closed positions so as to eliminate the need to separately rotate the lid and separately rotate the intermediate member.




It would also be advantageous if such an improved dispensing structure could be provided with an intermediate member and lid which can fit more closely together in the open position so as to present a more unified configuration in the open position that provides clear access to a larger dispensing aperture in the closure body.




It would also be beneficial if such an improved dispensing structure could accommodate the use of a molded, one-piece hinge connecting the closure body and intermediate member or connecting the intermediate member and the lid.




Further, it would be desirable if such an improved dispensing structure could accommodate a sealing lid system which would function to preserve the freshness of the product in the container when the dispensing structure is in a closed condition.




It would also be beneficial if such an improved dispensing structure could accommodate the use of a variety of different materials.




Further, it would be desirable if such an improved dispensing structure could be provided with a design that would accommodate efficient, high-quality, large volume manufacturing techniques with a reduced product reject rate.




The present invention provides an improved dispensing structure which can accommodate designs having the above-discussed benefits and features.




SUMMARY OF THE INVENTION




According to one aspect of the present invention, a dispensing system or structure is provided for a container that has an opening to the container interior. The dispensing structure includes a body for extending around the container opening. The body defines a first dispensing aperture communicating with the container opening.




The dispensing structure further includes an intermediate member which defines at least one second dispensing aperture that is smaller than the first dispensing aperture. The intermediate member is pivotable about an axis between (1) a closed position sealingly engaged with the body to locate the second dispensing aperture over the first dispensing aperture and block a peripheral portion of the first dispensing aperture which extends peripherally beyond the second dispensing aperture, and (2) an open position away from the closed position to permit complete access to the first dispensing aperture.




A lid is pivotable about the axis between (1) a lid closed position over the second dispensing aperture for sealingly engaging the intermediate member when the intermediate member is in its closed position whereby the second dispensing aperture is sealingly occluded, and (2) an open position away from the lid closed position to permit access to the second dispensing aperture when the intermediate member is in the closed position.




Numerous other advantages and features of the present invention will become readily apparent from the following detailed description of the invention, from the claims, and from the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT




While this invention is susceptible of embodiment in many different forms, this specification and the accompanying drawings disclose only one specific form as an example of the invention. The invention is not intended to be limited to the embodiment so described, however. The scope of the invention is pointed out in the appended claims.




For ease of description, the dispensing structure of this invention is described in the normal (upright) operating position, and terms such as upper, lower, horizontal, etc., are used with reference to this position. It will be understood, however, that the dispensing structure of this invention may be manufactured, stored, transported, used, and sold in an orientation other than the position described.




A presently preferred embodiment of a dispensing structure or system of the present invention is illustrated in

FIGS. 1-9

and is designated generally therein by reference number


20


in FIG.


1


. In the preferred embodiment illustrated, the dispensing structure


20


is provided in the form of a closure


20


which is adapted to be mounted on a container (not shown). The body of the container may have a suitable configuration with an upwardly projecting neck which may have a different cross-sectional shape than the container body.




The container would typically contain a liquid material, pasty material, powdered material, granular material, or other particulate material. The container may have a rigid wall or walls or may have a somewhat flexible wall or walls. The container defines an opening, typically at the upper end of the container neck (if the container has such a neck).




Although the container, per se, need not necessarily form a part of the present invention, per se, it will be appreciated that the dispensing structure or system of the present invention may be provided as a unitary portion, or extension, of the top of the container. However, in the preferred embodiment illustrated, the dispensing structure


20


is a separate element (i.e., a closure) which is adapted to be mounted to a previously manufactured container which has an opening to the container interior.




As shown in

FIG. 5

, the preferred embodiment closure or dispensing structure


20


of the present invention includes a base portion or body


30


, an intermediate member


40


, and a lid


50


. The intermediate member


40


, lid


50


, and body


30


are hingedly connected by means described in detail hereinafter. This accommodates movement of the lid


50


from a closed position (

FIG. 1

) to an open position (

FIG. 4

) while maintaining the lid


50


attached to the body


30


, and this also permits movement of the intermediate member


40


from a closed position (

FIG. 4

) to an open position (

FIG. 7

) while maintaining connection of the lid


50


, intermediate member


40


, and body


30


.




As illustrated in

FIGS. 2 and 3

, in the preferred embodiment of the dispensing structure


20


, the body


30


may be characterized as having or defining a skirt


62


for removably or non-removably receiving the upper end of the container (not illustrated). The skirt


62


interior includes suitable connecting means, such as a conventional thread


64


(

FIG. 2

) adapted to be threadingly engaged with a mating container thread (not illustrated). The closure body


30


and container could also be attached with either a dual snap-fit bead engagement or a mating bead and groove engagement.




Also, the closure body


30


could be permanently fixed to the container by means of induction melting, ultrasonic melting, gluing, or the like, depending upon the materials used for the closure body


30


and container. As previously mentioned, the closure body could also be formed as a unitary part, or extension, of the container.




The front exterior of the skirt


62


includes a thumb recess


63


. Above the recess


63


, as illustrated in

FIG. 4

, the top of the closure body


30


defines a peripheral deck


66


. A platform


70


extends upwardly from the deck


66


inwardly of the skirt


62


. The sidewall of the platform


70


has a bead


72


.




As shown in

FIG. 3

, a ring or collar


74


extends upwardly from the platform


70


. The collar


74


circumscribes, and defines, a first dispensing aperture


78


through the closure body


30


for communication with the container interior when the closure body


30


is mounted on the container. As can be seen in

FIGS. 2 and 3

, the collar


74


is higher at the front (adjacent the thumb recess


63


) than at the rear. However, the collar


74


could be lower at front if desired. On the inside of the collar


74


, there is a radially, inwardly extending, annular, flexible sealing flange


80


. The sealing flange


80


is adapted to deform for sealingly engaging a portion of the intermediate member


40


when the intermediate member is closed as illustrated in FIG.


2


.




At the rear of the closure body deck


66


are a pair of upwardly projecting hinge support posts


86


which each defines an upwardly open, partially cylindrical bearing surface


90


(FIG.


3


).




As shown in

FIG. 8

, the intermediate member


40


has a deck


102


surrounded by a downwardly depending skirt


104


. At the front of the skirt


104


, there is an outwardly projecting thumb lift or finger lift


106


. At the rear of the intermediate member


40


there are a pair of lugs


110


which each projects rearwardly from the intermediate member skirt


104


and which are joined near their distal ends by a generally cylindrical shaft or rod


120


defining a main hinge axis which is coincident with the axis of the cylindrical configuration of the rod


120


. The rod


120


is adapted to be received on the bearing surfaces


90


of the closure body posts


86


for rotation thereon. As can be seen in

FIG. 5

, the intermediate member lugs


110


and the closure body posts


86


are arranged such that the posts


86


are between the lugs


110


. If desired, the rod


120


could have a cross-sectional shape other than round, such as, for example, oval, triangular, etc. Such other shapes could be employed to effect a bias or preferred position with respect to the rod.




With reference to

FIG. 3

, the opening of each closure body post


86


above the bearing surface


90


is somewhat less than the diameter of the bearing surface


90


and somewhat less than the diameter of the intermediate member shaft or rod


120


. The portion of each post


86


at the opening to the bearing surface


90


is sufficiently flexibly resilient to accommodate insertion of the shaft or rod


120


in a snap-fit engagement which accommodates rotation of the shaft or rod


120


on each bearing surface


90


.




As shown in

FIG. 4

, the intermediate member deck


102


includes at least one second dispensing aperture


130


which is surrounded by a flange or spout


132


projecting upwardly from the deck


102


. The top, peripheral portion of the spout


132


includes a radially outwardly projecting, annular bead


134


.




As best illustrated in

FIG. 8

, the intermediate member


40


includes a downwardly projecting, annular flange


140


for sealingly engaging the sealing flange


80


on the closure body


30


when the intermediate member


40


is in the fully closed position (as illustrated in FIG.


2


).




As best illustrated in

FIG. 8

, the inside arcuate portion of the intermediate member skirt


104


includes a radially inwardly projecting bead


150


. As shown in

FIG. 2

, when the intermediate member


40


is in the fully closed position, the intermediate member skirt bead


150


is in snap-fit engagement beneath the overriding, mating bead


72


on the arcuate sidewall portion of the closure body deck platform


70


. This serves to retain the intermediate member


40


in the closed position unless and until it is forcefully disengaged by pushing upwardly on the thumb lift tab


106


(FIG.


4


).




The cover or lid


50


is shown in

FIGS. 6 and 9

as including a central portion or deck


202


and a downwardly depending, peripheral skirt


204


. Projecting outwardly from a front portion of the skirt


204


is a thumb lift


206


. Adjacent the thumb lift


206


is a notch


208


for accommodating the thumb lift


106


of the intermediate member


40


as shown in FIG.


1


.




As illustrated in

FIG. 9

, a rear portion of the lid


50


includes a pair of spaced-apart notches


210


. Between the notches


210


are a pair of lugs


212


, each lug


212


defines an upwardly open bearing surface


214


for receiving a portion of the rod or shaft


120


of the intermediate member


40


. When the lid


50


is mounted so that the intermediate member shaft


120


is received within the lid lug bearing surfaces


214


, the lid notches


210


receive the closure body posts


86


and the two intermediate member lugs


110


as can be seen in

FIGS. 4 and 5

.




As can be seen in

FIG. 9

, the lid


50


has a sealing flange or collar


240


which projects downwardly from the underside of the lid deck


202


. Adjacent the open distal end of the collar


240


there is an inwardly projecting, annular bead


250


. When the lid


50


is in the fully closed position as illustrated in

FIG. 2

, the lid collar


240


is received on the exterior of the intermediate member spout


132


, and the lid flange bead


250


is received below the spout bead


134


in a snap-fit engagement to hold the lid


50


closed unless and until the lid


50


is pivoted upwardly by pushing on the thumb lift


206


.




The dispensing structure


20


is easily used. A user typically encounters the dispensing structure


20


in an initially closed condition (

FIGS. 1 and 2

) mounted on a container (not shown). The user may initially lift the lid


50


by applying an upward force with a finger or thumb to the lid lift tab


206


. The lid


50


may be rotated to a fully opened position as shown in

FIG. 4

to expose the dispensing aperture


130


of the intermediate member


40


.




Instead of dispensing product from the container through the dispensing aperture


130


, the user may wish to also initially lift the intermediate member


40


with its lift tab


106


to a fully opened position as illustrated in FIG.


7


. However, to more efficiently use the system, the user could initially lift both the intermediate member


40


and lid


50


together upwardly from the closed position shown in

FIGS. 1 and 2

to an open position shown in FIG.


7


. The user could do this merely by lifting upwardly only on the intermediate member lift tab


106


.




With reference to

FIG. 6

, it will be appreciated that the intermediate member


50


fits within, and nests within, the lid


50


in the open position so as to provide a more compact configuration and so as to provide substantial clearance around the closure body dispensing aperture


78


.




The closure body dispensing aperture


78


may be relatively large to provide access to the interior of the container with a spoon or other implement or to accommodate pouring of a large stream of product through the dispensing aperture


78


.




If it is desired to dispense a smaller amount of product, such as a small diameter discharge stream of product, the intermediate member can be initially left in the closed position (FIG.


4


), or returned from the open position (

FIG. 7

) to the closed position (FIG.


4


). When the intermediate member


40


is in the closed position as shown in

FIG. 4

, the product can be discharged from the container through the intermediate member dispensing aperture


130


which may be substantially smaller than the closure body dispensing aperture


78


. When the intermediate member


40


is in the closed position illustrated in

FIG. 4

, the intermediate member flange


140


(

FIG. 2

) is sealingly engaged with the closure body flexible sealing flange


80


in the larger dispensing aperture


78


. Further, the deck portion


102


of the intermediate member


40


blocks a peripheral portion of the larger, first dispensing aperture


78


which extends peripherally beyond the smaller, second dispensing aperture


130


.




When the user is finished dispensing product through the dispensing closure


20


, the lid


50


may be returned to the closed position illustrated in

FIGS. 1 and 2

. If the intermediate member


40


was in an open position with the lid


50


, then both the intermediate member


40


and the lid


50


can be returned together to the closed position. In the closed position, the lid


50


is sealingly engaged with the intermediate member


40


to sealingly occlude the second dispensing aperture


130


and thus prevent flow out of the dispensing structure


20


.




It is presently contemplated that many applications employing the dispensing structure


20


will be most conveniently realized by molding the dispensing structure


20


from suitable thermoplastic material or materials. In the preferred embodiment illustrated, the body


30


, intermediate member


40


, and lid


50


could each be molded from a suitable thermoplastic material, such as polypropylene. The body


30


, intermediate member


40


, and lid


50


may be separately molded from the same material or from a different material. The materials may have the same or different colors.




It will also be appreciated that various retention structures, instead of the one described above, may be provided for releasably retaining the foraminous member


40


in the seated or closed position. Further, suitable interference-fit structures or latch structures, instead of the one described above, may be provided in conventional or non-conventional designs for releasably retaining the lid


50


in the closed position. Such conventional lid-retention structures can include a suitable interference fit or a snap-fit engagement between very small ribs (not illustrated) on the lid and body or a snap-fit engagement between a very small rib on the lid and a mating groove on the body or vice versa (not illustrated).




It will also be appreciated that the dispensing structure


20


can be readily designed to incorporate appropriate tamper-evident features and/or child-resistant features. Such features may be incorporated within the structure of the closure body and lid and/or may include overcap structures or shrink film systems (not illustrated).




When the intermediate member


40


is in an open position nested within the open lid


50


(FIG.


7


), the intermediate spout bead


134


is in snap-fit engagement with the lid collar bead


250


to retain the lid


50


and intermediate member


40


together in the nested relationship. This allows the user to more easily control the location of the lid


50


and intermediate member


40


, and this allows the user to more easily accommodate dispensing of product from the closure body dispensing aperture


78


.




In the embodiment illustrated in

FIGS. 1-9

, the closure body posts


86


are positioned between the intermediate member lugs


110


(FIG.


4


). However, it will be appreciated that in an alternate embodiment, the closure body posts


86


could be on the outside of the intermediate member lugs


110


. In such an embodiment, the rod or shaft


120


(

FIG. 8

) would extend laterally outwardly beyond each lug


110


for being received in the closure body posts


86


on the exterior of the lugs


110


.




Further, it will be appreciated that in an alternate embodiment, the rod or shaft


120


may be molded as part of the closure body posts


86


, and the intermediate member lugs


110


could be provided with cooperating open bearing surfaces for engaging the shaft


120


.




Also, in another alternate embodiment, the rod or shaft


120


could be molded as an extension of the lid lugs


212


, and the intermediate member lugs


110


could be provided with open bearing surfaces for engaging such a shaft on the lid.




In another embodiment, the intermediate member


40


and lid


50


could be molded together as a unitary structure connected by a thin portion of material defining a unitary hinge with an integral or unitary shaft (such as the shaft


120


illustrated in

FIG. 8

) for being received in the bearing surfaces


90


of the closure body posts


86


(FIG.


3


).




Alternatively, the intermediate


40


and closure body


30


could be molded together as a unitary structure connected by a thin piece of material defining a hinge with a unitary shaft, such as the shaft


120


(

FIG. 8

) molded as part of the structure for being received in the lid bearing surfaces


214


(FIG.


9


). In each of the above-described last two embodiments, the dispensing closure would be a two-piece closure rather than a three-piece closure as illustrated in

FIGS. 1-9

. Such a two-piece closure could have the advantage of a more simple assembly process.




It will also be appreciated that the dispensing structure of the present invention need not be provided as a separate closure for a container. The closure body, such as closure body


30


, could instead be molded as a unitary part of a container. A container having a peripheral wall forming an end that defines a container opening could be molded with a body portion extending radially inwardly from the container peripheral wall over the container end opening so as to form a unitary part of the container end and so as to define the first dispensing aperture, such as the dispensing aperture


78


illustrated in

FIG. 3

, that would be smaller than the container end opening.




In the embodiment illustrated in

FIGS. 1-9

, the dispensing structure is in the form of a closure which can be removably attached to a container by threaded engagement. It will be appreciated that other removable or non-removable attachment systems may be employed as discussed in detail above.




It should be understood that either the body first dispensing aperture


78


or the intermediate member second dispensing aperture


130


could include a pressure-openable valve, such as, for example, any of the slit-type valves disclosed in the U.S. Pat. No. 5,839,614, or modifications of such valves.




It will be readily apparent from the foregoing detailed description of the invention and from the illustrations thereof that numerous variations and modifications may be effected without departing from the true spirit and scope of the novel concepts or principles of this invention.
