DETAILED DESCRIPTION

Referring now to the drawings and particularly to FIG. 1, a refillable product dispenser system is shown and generally designated by the numeral 10. The system 10 includes an initial product package 12 and a refill product package 14. For the sake of clarity, not all reference numerals are necessarily present in each drawing figure. In addition, positional terms such as “upper,” “lower,” “side,” “top,” “bottom,” etc. refer to the container when in the orientation shown in the drawing. The skilled artisan will recognize that containers can assume different orientations when in use.
FIG. 2 schematically illustrates the components which may be included in the initial product package 12 and the refill product package 14. For example, in an embodiment, the initial product package 12 may include a reusable container 16, an initial product bag 18, and a reusable scoop 20. In another embodiment, the initial product package 12 may have product therein without an initial product bag 18, and with or without a reusable scoop 20. And in an embodiment, the refill product package 14 may include a disposable refill outer package 22, two or more refill product bags such as 24 and 26, and a second reusable scoop 28.
As best seen in FIGS. 3-5, the reusable container 16 may include a base or bottom 30, and a peripherally continuous generally vertically extending wall 32 defining a top opening 34. A lid 36 is associated with the wall 32 for closing the opening 34. The lid 36 may be pivotally connected to the peripheral wall 32 at hinges 38. The lid includes a latch 31 which engages a locking shoulder 33 extending from wall 32.
The base 30 and peripheral wall 32 may be described as forming a tub portion 35 of the container 16. The tub portion 35 may include a skirt 37 extending downwardly from the peripheral wall 32 below the base 30.
In certain embodiments, the container 16 may include a sealing lip 29 extending laterally outward near the open upper end thereof for providing a sealing engagement with the lid 36 when the lid is closed. Further details of exemplary forms of this embodiment of the construction of the container 16 and particularly of the sealing engagement of the lid 36 with flexible seal 29 are set forth in detail in U.S. patent application Ser. No. ______, entitled Improved Container Seal, attorney docket number MJE00287NP, assigned to the assignee of the present invention and filed on even date herewith, the details of which are incorporated herein by reference.
As seen in FIG. 3, the peripheral wall 32 has a generally oval cross-section which may also be described as an elongated cross-section having a length 40 and a width 42, with the sidewall 32 being curved across the end of the cross-section at the longitudinal end portions 44 and 46.
As best seen in FIG. 4, the opening 34 of the reusable container 16 may be defined by a smooth molded internal wall surface 48 which is free of any internally projecting lip or rib which would interfere with insertion and removal of the product bags such as 18, 24 or 26 as is further described below.
In an embodiment the lid 36 includes a scoop retention device including at least two flexible tabs 50 and 52 for resiliently holding either one of the scoops 20 or 28 in place on the underside of the lid 36.
The container 16 including the tub portion 35 and the lid portion 36 may be constructed by injection molding the same from a plastic material.
The initial product bag 18 is received in the container 16 and is constructed of a flexible material capable of being manipulated to decrease the volume occupied by the bag as the bag is partially or completely emptied during use. For example, as schematically illustrated in FIG. 6, the bag 18 may include a pleated upper portion 54 which may be folded over in an increasing number of folds as the bag is progressively emptied. The bag may also be manipulated in other ways, such as rolling the top portion, or in any other suitable manner. The initial product bag 18 has an initial volume filled with powdered infant formula 56. As seen in FIG. 2, the initial product bag 18 has an initial size and shape capable of being fully received in the container 16 so that the lid 36 can be closed.
As seen in FIG. 6, the initial product bag 18, when in its filled and sealed state, can be described as being generally parallelpiped in shape and having a bag bottom 58 defining a bag length 60 and a bag width 62. The bag bottom 58 may also be a pleated bottom portion 58 similar to the pleated top portion 54 previously described. The bag 18 further has an initial filled bag height 64. The initial volume of powdered infant formula 56 contained within the filled initial product bag 18 is approximately equal to the product of the length 60 times the width 62 times the height 64.
In an embodiment the bag length 60 and bag width 62 of the initial product bag 18 may be less than the length 40 and width 42, respectively, of the cross-section of the peripheral sidewall 32 of tub portion 35 of container 16.
The bag 18 may further include a reusable peelable adhesive strap 66 adhered to a sidewall 68 and the folded over upper portion 54 of the bag.
The use of a pleated foldable top portion 54 allows the initial product bag 18 to be fully opened over the entire bag length 60 and bag width 62 which aids in fully emptying the initial product bag, particularly for example if the user chooses to open the initial product bag and pour the contents thereof into the tub portion 35 of the container 16.
Referring now to FIG. 7, each of the refill product bags 24 and 26 is constructed similarly to the initial product bag 18 just described with a difference being that the refill product bags may be constructed to have a shorter initial filled bag height thus providing a refill volume which is less than the initial volume of the initial product bag 18.
Thus the refill product bags 24 and 26 may each have a bottom 70 defining a bag length 72 and a bag width 74, along with an initial filled refill bag height 76. The bottom 70 may be a pleated bottom, and the bag may have a pleated foldable top portion 78 held in place by a peelable strap 80.
The initial product bag and refill product bags may be constructed as resealable moisture proof bags. In the embodiment shown in FIG. 2, because the initial product bag 18 is itself a resealable moisture proof bag, there is no need for a tamper proof seal across the opening 34 of the tub portion 35, and thus the tub portion 35 may be initially closed only by the lid 36 and need not be sealed by a tamper proof peel off film or the like.
In an embodiment the flexible material from which the initial product bag 18 and/or the refill product bags 24 and 26 are constructed may comprise a multilayer material schematically indicated as 82 in FIG. 8. The multilayer flexible material may include an outer layer 83, a middle layer 85 and an inner layer 87. In an embodiment designed to provide a high oxygen and moisture barrier, the outer layer 83 may be a 48 gage polyethylene sheet, the middle layer 85 may be a 0.000285 inch thick metal foil, and the inner layer 87 may be a 3.0 mil easy open polyethylene sealant layer. The inner layer 87 may be described as a peelable sealing inner layer.
The outer layer 83 may be any suitable material that allows for printing of label information on the exterior surface of the product bags. Examples include polyethylene sheet and nylon sheet material.
The middle layer 85 may be any suitable metallic barrier layer. Examples include aluminum foil and metalized polyethylene.
The inner layer 87 may be any suitable sealable material that allows for a hermetic seal of the product bags. The seal may be formed by pressing two inner layers together and heating the joined sheets to melt them together to form a seal therebetween. Examples of suitable sealable materials include polyester and polyethylene.
When either the initial product bag 18 or the refill product bags such as 24 and 26 are initially filled with powdered infant formula, they may be filled under vacuum and then the pleated folded top portion such as 54 or 78 thereof is sealed by pressing together the inner layers 87 of opposed sheets of the flexible material. Alternatively, in some embodiments, the initial product bag 18 or the refill product bags such as 24 and 26 are filled while sparged with an inert gas such as nitrogen. A zip lock or other suitable seal may be formed between the opposed sheets. A tear-off strip or the like may be provided adjacent the seal to allow initial opening of the package to break the vacuum seal thereof.
In the embodiment illustrated in FIG. 2, the initial filled bag height 76 of the refill product bags 24 and 26 is less than the initial filled bag height 64 of the initial product bag 18 so that the refill product bags have a filled volume which is less than the filled volume of the initial product bag. By providing refill product bags having a smaller volume, this aids in insuring the freshness of the powdered infant formula in use due to less duration of exposure of the powdered infant formula to oxygen after its respective bag is opened. Optionally, the initial product bag 18 and the refill product bags such as 24 and 26 may be constructed to be of substantially identical volumes.
The refill product package 14 is shown in perspective view in FIG. 1 and in schematic elevation sectioned view in FIG. 2. The disposable refill outer package 22 thereof is generally rectangular parallelpiped in shape and has an outer package bottom 84 defining a package length 86 and a package width 88, and has a package height 90 greater than the package length 86. The outer package 22 may be constructed from cardboard or other recyclable packaging material. The top of the package 22 may be sealed for storage and display.
In the embodiment shown in FIG. 2, two refill product bags 24 and 26 are received in the refill outer package 22 and are shown stacked one on top of the other.
As previously noted and described with regard to FIG. 7, each of the refill product bags 24 and 26 is constructed of a flexible material and is generally parallelpiped in shape having the bag bottom 70 defining the bag length 72 and the bag width 74, and having the bag height 76. It is noted that the bag height 76 is less than the bag length 70, and the bag height 76 is less than one half of the package height 90. Further, the bag length 72 and bag width 74 are less than the package length 86 and package width 88, respectively. As also previously noted, each of the refill product bags 24 and 26 initially contains a refill volume equal to the bag length 72 times bag width 74 times bag height 76, which refill volume is initially filled with powdered infant formula.
As is also seen in FIG. 2, there may be room within the outer package 22 on top of the uppermost refill bag 26 for a second reusable scoop 28. The scoop 28 is preferably sealed in a disposable sanitary enclosure 92 which may for example be a transparent flexible cellophane package or the like. The scoop 20 of FIG. 2 is similarly sealed in a sanitary enclosure 21.
The initial product package 12 and refill product package 14 may include first and second identifying product indicia 94 and 96 placed thereon via labels or other suitable printing or the like. The first product indicia 94 identifies the brand, and nature of the product, such as powdered infant formula, contained in the initial product package 12. The second identifying indicia 96 on the outer package 22 of the refill product package 14 may indicate the usefulness of the refill product bags such as 24 and 26 with the reusable container 16 of the initial product package 12.
In another embodiment the refill product package may be constructed to include two or more refill product bags such as 24 and 26. In those other embodiments the refill product bags may be stacked one on top of the other or side by side or in any other suitable manner. And in yet another embodiment the refill product bags may be marketed individually without any outer package 22.
In an embodiment the refillable product dispenser system 10 may be used in the following manner. The parents or other caretaker of a newborn infant may purchase, or may receive at the hospital, the initial product package 12 which includes the container 16, the initial product bag 18 which is full of powdered infant formula product, and the reusable scoop 20 sealed within sanitary packaging 21. The initial product bag 18 itself is a moisture proof sealed package. The reusable container 16 with its closed lid 36 engaging sealing lip 29 provides a second protective barrier for the contents. The user may at the same time purchase one or more of the refill product packages 14, although that is optional. Refill product packages 14 may be procured at a different time and place.
Upon first use, the user will open the lid 36 of the container 16, remove the scoop 20 therefrom, and open the initial product package 18 to access the contents thereof. The contents of the initial product package 18 may be accessed in one of two ways at the user's option.
First, the user may leave the initial product bag 18 in place within the container 16 and open the top portion 54 of the bag to access the powdered infant formula 56. After removing the desired portion of powdered infant formula with the scoop 20, the top portion 54 of the partially emptied bag 18 may be resealed and folded back over and may be held in place with the peelable strap 66. The scoop 20 may be placed on the underside of lid 36 utilizing the tabs 50 and 52 as seen in FIG. 3, then the lid 36 is closed until the next usage.
Alternately, the user may choose to remove the initial product bag 18 from the container 16, open the top portion 54 of the initial product bag 18, and dump the entire contents of the initial product bag 18 into the tub portion 35 of container 16. Then the scoop 20 is utilized to extract the desired portion of powdered infant formula from the tub portion 35, then the scoop is placed on the underside of lid 36 and the lid is closed until the next usage.
When the contents of the initial product bag 18 have been used, the reusable container 16 may be refilled using one of the refill product bags such as 24 or 26. The refill product bags may be used in either of the optional manners as described above for the initial product bag 18, namely they may either be placed within the tub portion 35 and powdered infant formula may be removed directly from the refill bag, or the bag may be dumped into the tub portion 35.
In an embodiment, the materials from which the outer refill package 22, and the initial product bag 18 and refill product bags 24 and 26 are constructed may be completely recyclable materials.
A user of the system 10 can purchase one of the initial product packages 12, and then purchase multiple refill product packages 14 throughout the infant's formula feeding period of approximately one year.
The use of such a refillable infant formula packaging system 10 provides economic savings due to the lesser expense of purchasing infant formula in the refill packaging as opposed to purchasing a new exterior container 16 each time a new quantity of infant formula is needed. Additionally, significant environmental sustainability improvements are provided due to the lesser overall packaging materials utilized to provide powdered infant formula to the infant.
The use of a tub having an opening 34 without any pronounced internally protruding lip allows for easy removal of the initial product bag 18 and replacement thereof with a replacement product bag. Furthermore, the absence of a pronounced inward protruding lip makes it easier to remove all of the contents from the tub portion 35 if the powdered infant formula is dumped directly into the tub portion 35.
The use of a peelable sealing pouch material such as the inner layer 87 shown in FIG. 8 makes for easy opening of the product bags. Optionally other easy opening bag designs may be utilized.
The use of a bag with a full opening upper end such as the pleated folded upper ends 54 and 78 facilitates easy dumping of the entire contents of the bag into the tub if that option is selected.

Example

In an embodiment, the tub portion 35 may have a length 40 of approximately 152 mm, a width 42 of approximately 102 mm and a height 45 of approximately 136 mm. The initial product bag 18 may have a bag length 60 of approximately 130 mm, a bag width 62 of approximately 70 mm, and an initial bag height 64 of approximately 116 mm. The refill outer package 22 may have a length 86 of approximately 146 mm, a width 88 of approximately 89 mm, and a height 90 of approximately 254 mm. Each of the refill product bags 24 and 26 may have a bag length 72 of approximately 130 mm, a bag width 74 of approximately 70 mm, and an initial bag height 76 of approximately 116 mm. Alternatively the refill product bags may have an initial bag height 76 in the range of from 80 to 100% of the initial bag height 64 of the initial product bag.
Thus it is seen that the apparatus and methods of the present disclosure readily achieve the ends and advantages mentioned as well as those inherent therein. While certain preferred embodiments of the disclosure have been illustrated and described for purposes of the present disclosure, numerous changes in the arrangement and construction of parts and steps may be made by those skilled in the art which changes are encompassed within the scope and spirit of the present disclosure as defined by the appended claims.
