Description




FIELD OF THE INVENTION




The present invention relates to dispensers capable of dispensing items that are maintained in a roll format and, more particularly, to a dispenser capable of dispensing items that are maintained in a roll format, wherein the items include a top, self-adhesive layer and a lower release layer.




BACKGROUND OF THE INVENTION




The United States Post Office has recently provided customers with the option of self-adhesive stamps. For convenience sake, a customer has the further option of buying the self-adhesive stamps in a 100 stamp roll configuration. Without any type of storage and/or dispensing device, the roll configuration is somewhat awkward tending to unwind and/or flop around undesirably. Further, without any type of dispensing device, the user is required to peal away the release liner beneath the self-adhesive stamp. However, because the release liner is the same size as the stamp, i.e., no edge extending beyond the length or width of the stamp, the user must attempt to slide a fingernail or other lifting means beneath the stamp to remove it from the release liner. While removing the stamp from the release liner is not overly burdensome, it can become frustrating and tedious.




As such, various types of stamp dispensers have been developed to aid in the storage and removal of self-adhesive stamps from the release liner. For example, U.S. Pat. No. 5,863,384 describes a self-adhesive postage stamp dispenser and applicator that includes a housing with an insertable cartridge. The insertable cartridge incorporates a ratchet wheel that is attached to a strap for grabbing the release liner. Once the release liner is grabbed, it is drawn inside the housing and wrapped about a spool in the cartridge. The numerous components, e.g., housing, cartridge, ratchet wheel, strap and spool, add complexity and cost to the design. Further, because the release liner is spooled within the housing and cartridge, the possibility of a jam, e.g., the bunching of the release liner within the cartridge, exists.




U.S. Pat. No. 5,851,347 describes a stamp affixer apparatus and method. The affixer in this case includes a rotatable housing as well as two gear assemblies and a drive roller. And, as with the earlier described patent, the release liner is spooled within the housing. Once again, the numerous components add to the complexity and cost of the design while the inner spooling of the release liner presents the possibility of a jam.




Thus, there is a need for a self-adhesive stamp dispenser that has a minimal number of distinct components to reduce the cost and complexity of manufacture of the dispenser. Further, there is a need for a dispenser that eliminates the interior spooling of the release liner to reduce the possibility of jams, and thus, the resetting of the dispenser for operation.




SUMMARY OF THE INVENTION




The needs described above are in large measure met by a self-adhesive stamp dispenser of the present invention. The dispenser has only two components, a housing and a roller, thereby reducing the cost and complexity of manufacture and, as well, eliminates the need for interior spooling of the release liner. More specifically, the dispenser includes a housing, having a base portion and a lid portion, and a roller incorporating a tacky surface. The base portion generally includes a stamp cavity for storing the roll of self-adhesive stamps and a roller cavity, which incorporates a number of extending ribs. The roller is positionable within the roller cavity and interfaces with the ribs of the base portion to pull the release liner and expel the release liner through the base portion. The lid portion is releasably closeable over the base portion.




Upon closing the lid portion over the base portion, at least part of the roller extends up through the lid portion thereby presenting itself for manual propulsion. As indicated above, the roller is preferably provided with a tacky surface to aid in propulsion and in the pulling and expelling of the release liner. Both the lid portion and the base portion are preferably provided with a resistance feature. This resistance feature is generally in the form of an extending wall or rib and helps to separate the self-adhesive items from each other upon being dispensed from the dispenser. Further, both the lid portion and the base portion are preferably provided with a centering feature to aid in the centering of the self-adhesive stamps within and about the dispenser. Lid portion and base portion may be unitary in nature, i.e., connected by a living hinge, allowing them to be manufactured as a single mold. Alternatively, the lid portion and the base portion may be manufactured as distinct components and connected via a mechanical hinge.

Roller


16


is depicted in detail in

FIGS. 6-11

, wherein

FIGS. 6-8

depict roller


16


prior to over-molding, and

FIGS. 9-11

depict roller


16


after over-molding. Referring to

FIGS. 6-8

, roller


16


is defined by a pair of end wheels


140


and a central shaft portion


142


. End wheels


140


are preferably provided with a toothed edge


144


in preparation for over-molding. Central shaft portion


142


is provided with four central rollers


146


each of which is separated from the other by a spacer


148


having a cross-hatch configuration having a lesser diameter than central rollers


146


. Each central roller


146


incorporates a notch or gap


150


in preparation of over-molding. Further, a pair of spacers


152


, of significantly reduced diameter, separates central shaft


142


from end wheels


140


. Roller


16


, as depicted in

FIGS. 6-8

, is preferably molded as an integral unit from polypropylene or other suitable material.




Referring to

FIGS. 9-11

, roller


16


as depicted in

FIGS. 6-8

has now been completely over-molded with a layer


154


of thermoplastic elastomer that preferably has a durometer in the 40's, e.g., 40±5%, and provides roller


16


with a tacky surface. As shown, toothed edge


144


and gap


150


have been filled in by elastomer layer


154


and a tacky surface is now present.




II. Self-Adhesive Item Dispenser—Assembly




The assembly of self-adhesive item dispenser


10


is depicted in

FIGS. 1

,


12


, and


13


. To begin assembly, base portion


12


and lid portion


14


are laid out in their open or molded orientation, as depicted in

FIGS. 1 and 12

. Over-molded roller


16


is then positioned within roller cavity


40


. When positioned within roller cavity


40


, end wheels


140


of over-molded roller


16


are positioned within troughs


44


while spacers


152


are inserted within and supported by elongate notch


60


thereby allowing roller


16


to rotate freely, i.e., without contacting any other component of dispenser


10


. Central rollers


146


are unobstructed during rotation as tines


42


and ribs


52


have been designed to be in substantial alignment with spacers


148


of central shaft


142


.




Next, a 100-roll


156


of self-adhesive stamps is placed within stamp holding cavity


32


so as to unwind in a clock-wise direction. Elongate rib


34


within stamp holding cavity


32


operates to center roll


156


within stamp holding cavity


32


. Two to three stamps


158


are then preferably removed from a release liner


160


so that release liner


160


may be pulled forward over over-molded roller


16


. Release liner


160


is further pulled forward over the top of upper wall


36


and lip edge


80


. Release liner


160


is then pulled to the underside of base portion


12


where it is inserted through gap


54


and exited out gap


45


such that release liner


160


runs over support ribs


52


(see FIGS.


4


and


5


).




As release liner


160


is placed in contact with ribs


52


, central rollers


146


of roller


16


are also engaged as ribs


52


force release liner to maintain a lifted position over cross-bar


44


. The tackiness of over-molded roller


16


enables central rollers


146


to grab release liner


160


against ribs


52


and, as such, a clock-wise propelling motion of end wheels


140


causes release liner


160


to be propelled out gap


45


. Serrated lip edge


46


on cross-bar


44


at gap


45


allows any excess release liner


160


to be torn away as desired.




With roll


156


and release liner


160


appropriately positioned within base portion


12


, lid portion


14


is raised up from its open orientation (flexing a living hinge


18


), placed down atop base portion


12


, and locked in position to complete a closed orientation of dispenser


10


. In the closed orientation, side walls


98


of stamp cap portion


90


straddle side walls


26


of stamp holding portion


20


. The curvedly recessed configuration side walls


98


allow a user to grasp side walls


26


of base portion


12


proximate forward edge


102


without feeling the awkward interference of side walls


98


.




Further, in a closed orientation, a top portion of each of end wheels


140


extends up through gap


118


. Shallow tab


110


is inserted within elongate notch


60


whereby shallow tab


110


is positioned over spacer


152


of previously inserted over-molded roller


16


helping to maintain roller


16


in an operable position. Locking tab


112


extends down over shallow notch


72


whereby lip edge


114


engages lock edge


74


to hold lid portion


14


tight to base portion


12


. Additionally, side walls


124


of dispensing cap portion


94


straddle side walls


38


and, as well, rest atop sealing edge


76


. A base portion of dispensing lip portion


126


also rests atop sealing edge


76


while the remaining portion extends beyond sealing edge


76


. An upper portion of side walls


38


engages groove


134


. Thus, interior side walls


106


of roller cap portion


92


along with side walls


38


of intermediate roller holding portion


22


and grooves


134


of dispensing cap portion


94


, operate to center the unrolling stamps


158


and release liner


160


as they move through dispenser


10


. Guide walls


77


operate to center release liner


160


as it is fed into gap


54


.




Additionally, with respect to the movement of stamps


158


and release liner


160


through dispenser, hollow


120


allows stamps


158


and release liner


160


to traverse through dispenser


10


without touching over-molded roller


16


. In other words, over-molded roller


16


is not used to push stamps


158


out by pushing release liner


160


rather over-molded roller


16


is used only to pull release liner


160


across cross-bar


44


whereby release liner


160


is forced out/expelled through gap


45


. The curved underside of tines


42


keep release liner


160


traveling outward through gap


45


rather than bunching up within roller cavity


40


. Pushing of stamps


158


and release liner


160


with over-molded roller


16


would cause a large loop of stamps


158


/release liner


160


to form thereby hindering operation of dispenser


10


.




Further, upper wall


36


of upper dispensing portion


24


keeps stamps


158


and release liner


160


lifted upward preventing bunching within upper dispensing portion


24


while ridge


136


of dispensing cap portion


94


directs stamps


158


and release liner


160


downward, which also helps to prevent bunching within upper dispensing portion


24


. The combination of upper wall


36


and ridge


136


also creates a resistance or tension against stamps


158


, and release liner


160


, so that they may easily be dispensed and separated from the following stamp


158


.




The opening and restocking of dispenser


10


may be achieved simply by extending one or both of locking tabs


112


outward to release lid portion


14


from base portion


12


.




III. Self-Adhesive Item Dispenser—Use




Self-adhesive item dispenser


10


, once assembled as described above, may now be used to dispense and to apply self-adhesive stamps


158


. To dispense one stamp


150


, one or both of end wheels


140


is propelled forward, i.e., in a clock-wise motion, whereby over-molded roller


16


grabs release liner


160


. Upon being grabbed by over-molded roller


16


, release liner


160


is pulled downward and away from stamp


158


such that the free edge of stamp


158


is presented, i.e., extending over dispensing lip edge


80


and preferably just past the front edge of dispensing lip portion


126


. The free edge of stamp


158


may then be placed at a desired position on an envelope. The rear portion of dispenser


10


is lifted upward causing dispensing lip portion


126


to press downward onto stamp


158


thereby affixing stamp


158


in position. Drawing dispenser


10


back while still pressing downward with dispensing lip portion


126


on stamp


158


, with the aid of the resistance caused by upper wall


36


and ridge


136


, causes stamp


158


to separate from the following stamp


158


.




With one stamp


158


dispensed, the user is able to see, via slots


132


, that the following stamp


158


is positioned directly under dispensing lip portion


126


and may now propel one or more of wheel ends


140


forward such that the free edge of stamp


158


is presented in the desired fashion, i.e., extending over dispensing lip edge


80


and preferably just past the front edge of dispensing lip portion


126


, for the next application.




In view of the above, self-adhesive item dispenser


10


of the present invention provides a user not only with a convenient dispenser but also with an applicator and a compact self-adhesive stamp storage device all in one unit.




IV. Self-Adhesive Item Dispenser—Alternative Embodiments





FIGS. 14 and 15

depict an alternative embodiment of self-adhesive item dispenser


10


of the present invention. In this embodiment, a rolling pin


170


replaces ribs


52


and is supported by cross-bar


44


. Release liner


160


fed into gap


54


, then between over-molded roller


16


and rolling pin


170


, and out gap


45


whereby release liner


160


is directed downward and outward by tines


42


. While operating similarly to the earlier-described embodiment, the present embodiment utilizes a separate and distinct additional component, i.e., rolling pin


170


, that adds cost and complexity to dispenser


10


.





FIGS. 16 and 17

depict yet another alternative embodiment of self-adhesive item dispenser


10


of the present invention. In this embodiment, cross-bar


44


and its ribs


52


are replaced by a lower lid portion


180


that is connected to base portion


12


via another living hinge


182


. Lower lid portion


180


incorporates a plurality of arcuately-shaped ribs


184


such that when lower lid portion


180


is closed against base portion


12


and over-molded roller


16


, ribs


184


operate to press release liner


160


against roller


16


. Lower lid portion


180


is provided with a serrated lip edge


186


for tearing of excess release liner


160


.




In assembling dispenser


10


of

FIGS. 16 and 17
