Abstract

A liquid dispenser system for use with an apparatus for forming and filling pouched products, the system comprising a first fluid dispenser shoe, the first fluid dispenser shoe comprising an inlet bore for placing in fluid communication with a source of liquid to be dispensed; at least one liquid dispensing manifold in fluid communication with the inlet bore; and a plurality of exit orifices positioned along the at least one liquid dispensing manifold for dispensing the liquid on an outer surface of the pouched product, wherein the first fluid dispenser shoe is positioned downstream of the apparatus for forming and filling pouched products and adjacent a stream of pouched products as they exit the apparatus.

First claim

What is claimed:

1. A system for producing pouched tobacco products comprising:
an apparatus for forming and filling pouched products; and
a liquid dispenser system including a first fluid dispenser shoe, said first fluid dispenser shoe comprising:
(a) an inlet bore for placing in fluid communication with a source of liquid to be dispensed;
(b) at least one liquid dispensing manifold in fluid communication with said inlet bore; and
(c) a plurality of exit orifices each having a diameter of about 0.2 mm, positioned along said at least one liquid dispensing manifold for dispensing the liquid by capillary or wicking action on an outer surface of the pouched product,

wherein said first fluid dispenser shoe is positioned downstream of the apparatus for forming and filling pouched products and adjacent a stream of pouched products as they exit the apparatus.

2. The system of claim 1 , wherein said first fluid dispenser shoe comprises a block for forming said at least one liquid dispensing manifold within.

3. The system of claim 2 , wherein said block of said first fluid dispenser shoe is rectangularly configured.

4. The system of claim 3 , wherein said at least one liquid dispensing manifold is formed within said block so as to be substantially perpendicular to the stream of pouched products exiting the apparatus.

5. The system of claim 4 , further comprising a second fluid dispenser shoe, said second fluid dispenser shoe positioned substantially parallel to said first fluid dispenser shoe and spaced apart therefrom so as to permit the stream of pouched products to pass therebetween and receive the dispensed liquid on at least two sides thereof.

6. The system of claim 5 , further comprising a plurality of liquid dispensing manifolds each aligned substantially parallel with respect to one another.

7. The system of claim 6 , wherein each liquid dispensing manifold includes at least four exit orifices.

8. The system of claim 6 , wherein each liquid dispensing manifold includes at least six exit orifices.

9. The system of claim 6 , wherein each liquid dispensing manifold includes at least eight exit orifices.

10. The system of claim 9 , further comprising a bracket member for mounting said first and second fluid dispenser shoe, said second fluid dispenser shoe positioned substantially parallel to said first fluid dispenser shoe and spaced apart therefrom so as to permit the stream of pouched products to pass therebetween and receive the dispensed liquid on at least two sides thereof.

11. A system for making a pouched product, the system comprising:
(a) means for supplying a web material for forming a pouch;
(b) an apparatus for forming and filling the pouched product, the apparatus including an elongated tubular member, said elongated tubular member having a first end, a second end and an outer surface, said outer surface of said elongated tubular member providing a surface for forming the pouched product from the supply of web material;
(c) a forming shoulder, said forming shoulder receiving the web from said supply of web material and folding the web about said apparatus to form the pouch having longitudinal edge portions;
(d) a heated knurled disc for sealing the longitudinal edge portions of the web to form a seam as the web is drawn along said apparatus;
(e) a liquid dispenser system comprising a first fluid dispenser shoe, said first fluid dispenser shoe comprising
(i) an inlet bore for placing in fluid communication with a source of liquid to be dispensed;
(ii) at least one liquid dispensing manifold in fluid communication with said inlet bore; and
(iii) a plurality of exit orifices each having a diameter of about 0.2 mm, positioned along said at least one liquid dispensing manifold for dispensing the liquid by capillary or wicking action on an outer surface of the pouched product,

wherein said first fluid dispenser shoe is positioned downstream of the apparatus for forming and filling pouched products and adjacent a stream of pouched products as they exit the apparatus.

12. The system of claim 11 , further comprising drive belts or drive wheels located below said forming shoulder to continuously pull the web through said forming shoulder.

13. The system of claim 12 , further comprising an upper pair of opposing heat-sealing elements and a lower pair of heat-sealing elements to cooperate with a knife to repetitively seal and sever pouched product.

14. The system of claim 13 , wherein discrete charges of tobacco are fed through said elongated inner tubular member of said apparatus in timing with the operation of said heat-sealing elements.

15. The system of claim 14 , wherein said heat-sealing elements and knife follow a motion cycle wherein said heat-sealing elements close together and tobacco is fed into said elongated inner tubular member of said apparatus.

16. The system of claim 15 , wherein metered portions of tobacco are blown via air into said elongated tubular member of said apparatus after the upper heat-sealing elements are closed.

17. The system of claim 16 , wherein a liquid comprising one or more flavorants is fed to said liquid dispenser system thereby providing at least a partial coating of the one or more flavorants.

18. The system of claim 11 , wherein said first fluid dispenser shoe comprises a block for forming said at least one liquid dispensing manifold within.

19. The system of claim 18 , wherein said block of said first fluid dispenser shoe includes a track member, and wherein the exit orifices are located within the track member.

20. The system of claim 19 , further comprising a second fluid dispenser shoe including a track member with exit orifices located therein, said second fluid dispenser shoe positioned substantially parallel to said first fluid dispenser shoe and spaced apart therefrom so as to form a channel defined by said track members to permit the stream of pouched products to pass therethrough and receive the dispensed liquid on at least two sides thereof.

21. The system of claim 20 , further comprising a plurality of liquid dispensing manifolds each aligned substantially parallel to one another.

22. The system of claim 21 , wherein each liquid dispensing manifold includes at least four exit orifices.

23. The system of claim 21 , wherein each liquid dispensing manifold includes at least six exit orifices.

24. The system of claim 21 , wherein each liquid dispensing manifold includes at least eight exit orifices.

25. The system of claim 24 , further comprising a bracket member for mounting said first and second fluid dispenser shoe, said second fluid dispenser shoe positioned substantially parallel to said first fluid dispenser shoe and spaced apart therefrom so as to permit the stream of pouched products to pass therebetween and receive the dispensed liquid on at least two sides thereof.

26. A method of forming a pouched flavored product, comprising:
(a) providing a web for use in forming the pouched flavored product;
(b) forming and filling a pouched flavored product using an apparatus having an elongated tubular member, the elongated tubular member having a first end, a second end and an outer surface, the outer surface of the elongated tubular member providing a surface for forming the pouched flavored product thereabout; and
(c) providing a liquid comprising one or more flavorants to a liquid dispenser system comprising a first fluid di
