Dispenser for cup-shaped articles with improved clamp-ring securement feature
View Patent ↗A dispenser for cup-shaped articles comprises a body defining a storage region for receiving an associated stack of cups or other cup-shaped articles. The body comprises an open end that communicates with the storage region. A resilient diaphragm restricts the open end of the body. A clamp member is releasably secured adjacent the open end of the body and retains the diaphragm relative to the open end of the body. A mounting flange projects outwardly away from the body. The clamp member and mounting flange comprise mating structures that releasably secure said clamp member to the mounting flange.
1. A dispenser for cup-shaped articles, said dispenser comprising:
a body defining a storage region adapted for receiving for an associated stack of cup-shaped articles;
a mounting collar connected to said body, said mounting collar including a flange projecting outwardly therefrom;
a resilient diaphragm located adjacent an open end of said storage region of said body, said diaphragm restricting said open end for controlled dispensing of associated cup-shaped articles from within said storage region;
a clamp-member engaged with said mounting collar to secure said diaphragm adjacent said open end of said storage region of said body, said clamp-member including a plurality of notches defined in a wall thereof;
a plurality of projections connected to said flange of said mounting collar, wherein each of said plurality of projections is received in a corresponding one of said notches with a resilient snap-fit when said clamp-member is engaged with said mounting collar, and wherein said clamp-member is selectively separable from said mounting collar by exertion of a pulling force thereon sufficient to cause said projections to disengage from said notches;
wherein said clamp-member further comprises indicia to indicate a location of at least one of said plurality of notches to allow for alignment of said at least one notch with one of said projections of said mounting collar flange.
2. The dispenser as set forth in claim 1 , wherein each of said projections comprises a resiliently deflectable tab including an enlarged outer end, wherein each of said resiliently deflectable tabs is defined as a one-piece construction with said flange of said mounting collar.
3. The dispenser as set forth in claim 2 , wherein said mounting collar, said flange, and said plurality of projections are all defined together as a one-piece molded polymeric construction.
4. The dispenser as set forth in claim 1 , wherein each of said plurality of projections comprises a button-like member secured to said flange.
5. The dispenser as set forth in claim 4 , wherein said button-like member of each of said studs is secured to said flange of said mounting collar by a fastener.
6. The dispenser as set forth in claim 1 , wherein said body defines a plurality of bosses, and wherein said mounting collar comprises a plurality of recesses into which said bosses are respectively received to provide a releasably connection between said mounting collar and said body.
7. The dispenser as set forth in claim 1 , wherein said mounting collar comprises a tubular projection including an outermost edge, and wherein said diaphragm is mounted to said outermost edge of said tubular projection.
8. The dispenser as set forth in claim 7 , wherein said outermost edge of said tubular projection comprises a radially enlarged bite tooth extending at least partially therearound.
9. The dispenser as set forth in claim 1 , wherein said open end of said storage region of said body extends through said mounting collar, and wherein said diaphragm is placed in covering relation over said open end.
