Abstract

A flowable substance dispenser for use with at least one flexible bag, each bag capable of holding one or more flowable substances, the dispenser comprising a hollow tubular body, adapted to receive the flexible bag, and a plunger assembly. The tubular body includes a proximal end, a distal end, an inner periphery, an outer periphery, one or more longitudinal slots, and at least one transverse exit port disposed near the distal end of the tubular body. The plunger assembly includes a piston adapted to slide within the tubular body, a ring member having an inner periphery adapted to fit around the outer periphery of the tubular body, and a transverse bar attached to the inner periphery of the ring member. The bar is adapted to slide within the one or more slots and is capable of engaging the piston.

9. The dispenser according to claim 8 wherein said support member further comprises:

a tubular support wall having an inner periphery and an outer periphery; and

an opening in said support wall;

wherein said opening and said exit port are capable of being at least partially aligned.

10. The dispenser according to claim 8 further comprising a spigot means attached to said support member.

11. The dispenser according to claim 10 wherein said spigot means further comprises a piercing means capable of being inserted into said flexible bag.

12. The dispenser according to claim 1 further comprising a spigot means attached to said hollow tubular wall surrounding said exit port.

13. The dispenser according to claim 10 wherein said spigot means is disposed in communication with one of said exit ports.

14. The dispenser according to claim 10 further comprising a cap adapted to releasably engage said spigot means.

15. The dispenser according to claim 8 wherein said support member further comprises a baffle means for dividing the interior of said support member into first and second portions capable of receiving first and second flexible bags, respectively.

16. The dispenser according to claim 15 wherein at least one of said exit ports intersects said first portion, said second portion, and said baffle means.

17. A dispenser for use with one or more flexible bags containing flowable contents, said dispenser comprising:

a hollow receptacle means for receiving the one or more flexible bags;

a longitudinal slot means disposed in said receptacle means;

an exit means disposed in said receptacle means for providing an outlet path for the contents of the flexible bag; and

a plunger means for forcing the contents out of the flexible bag, said plunger means including;

a piston means disposed within said receptacle means for engaging said one or more flexible bags;

a circumferential grip means extending substantially around the outer periphery of said hollow receptacle means and adapted to slide therealong;

a transverse member attached to said grip means and adapted to extend through said slot means and through the interior of said receptacle means, wherein said transverse member is capable of engaging said piston;

wherein movement of said circumferential grip means toward said one or more flexible bags causes said plunger to move toward said bags, thereby causing said bags to compress and eject any flowable contents therein out through said exit means.

18. The dispenser according to claim 17 further comprising a dispensing end member attached to said hollow receptacle means, said dispensing end member having an opening in communication with said exit means.

19. The dispenser according to claim 17 wherein said hollow receptacle means further comprises an elongated hollow tube having:

an open proximal end;

an open distal end;

a cap member disposed over said proximal end; and

a dispensing end member disposed over said distal end.

20. A dispenser, for use with one or more flexible bags containing one or more flowable oral care substances, comprising:

a hollow tubular body adapted to receive said flexible bags, said tubular body including;

a proximal end,

a distal end,

an inner periphery,

an outer periphery,

one or more longitudinal slots, and

one or more exit ports disposed near the distal end of said tubular body;

a plunger adapted to slide within said tubular body;

an actuating means adapted to slide within said one or more slots and capable of engaging said plunger, said actuating means including;

a ring member having an inner portion adapted to fit around said tubular body, and

a transverse support bar fixedly attached to the inner portion of said ring member;

a proximal end member adapted to fit over the proximal end of said hollow tubular body; and

a distal end member adapted to fit over the distal end of said hollow tubular body

wherein said plunger is disposed between said one or more flexible bags and said actuating means;

wherein movement of said actuating means toward the distal end of said hollow tubular body is capable of compressing said one or more bags and expelling their contents through said one or more exit ports.

21. The dispenser according to claim 20 wherein said distal end member is further adapted to support said hollow tubular body and said flexible bags in a substantially vertical direction.

22. The dispenser according to claim 20 wherein said distal end member further comprises one or more exit openings adapted to communicate with at least one of said exit ports, and wherein the contents of at least one of said bags are capable of flowing through at least one of said exit openings.

23. The dispenser according to claim 20 wherein said at least one of said flexible bags is provided with indicia visible through at least one of said slots.

24. The dispenser according to claim 20 wherein each of said flexible bags further comprises a pre-formed hole.
