(h) said upper closure flap including;

(i) an upper section foldably joined at its upper edge to said shell one major side wall panel, along a first fold line; and

(ii) a lower section joined at its upper edge to a lower edge of said upper section, along a second fold line that is parallel to said first fold line;

(iii) both of said upper closure flap sections being detachably joined to said shell one side wall panel by a pair of separate, laterally spaced, generally vertically extending, upper lines of weakness extending downwardly from opposite ends of said first fold line;

(i) said lower closure flap being foldably joined to said shell one minor side wall panel along a third fold line, extending parallel to said first and second fold lines, and being detachably joined to said one end wall by a pair of laterally spaced, generally vertically extending, separate, lower lines of weakness extending upwardly from opposite ends of said second fold line;

(j) said lower section being detachably joined to said lower flap by a common, central line of weakness that extends between adjacent ends of said upper and lower lines of weakness;

(k) said lower flap being arranged and disposed to be pushed inwardly to partially detach it from said one end wall and said upper flap to allow insertion of a finger to grasp said pour spout.

2. A carton according to claim 1, wherein said pour spout center section includes a recess in an upper edge thereof to facilitate grasping of the pour spout by a finger.

3. A carton according to claim 1, wherein said pour spout side sections each includes a projection extending upwardly from an outer corner thereof for engagement with said shell one minor side wall panel to prevent said pour spout from accidentally being pulled too far out of said shell.

4. A carton according to claim 1, wherein said upper flap is generally pie-shaped.

5. A carton according to claim 1, wherein said lower closure flap is arcuate in shape.

6. A carton according to claim 1, wherein said upper lines of weakness converge downwardly.

7. A carton according to claim 1, wherein said lines of weakness are formed by double cut scores.

8. A two-piece carton with a sift-resistant opening feature and reclosable dispensing feature, said carton comprising:

(a) a shell including opposed major and minor side wall panels foldably joined to each other to form an outer tubular structure open at the ends;

(b) upper and lower end flaps foldably joined to upper and lower ends of said side wall panels and secured to each other in overlapped relationship to close said structure open ends;

(c) one of said shell minor side wall panels having, extending therethrough adjacent an upper end thereof, a dispensing opening covered by a pair of contiguous, partially detachable reclosable, upper and lower, closure flaps foldably joined, along parallel fold lines, to said one side wall panel adjacent said dispensing opening;

(d) a liner including opposed major and minor side wall panels foldably joined to each other to form an inner tubular structure positioned within said shell;

(e) one of said liner minor side panels being positioned against an inner surface of said shell one minor side wall panel;

(f) said liner one side panel including an integral pour spout located adjacent said shell dispensing opening, arranged and disposed to be pulled part way out of the carton through said dispensing opening;

(g) said liner pour spout comprising;

(i) a center section having a lower edge foldably joined to a remaining portion of said liner one side panel;

(ii) a pair of side sections foldably joined to opposed side edges of said center section and free from attachment to said liner one side panel remaining portion;

(h) said lower closure flap being arranged and disposed to be pushed inwardly to partially detach it from said one end wall and said upper flap, to allow insertion of a finger to grasp said upper closure flap to lift it, and to grasp said pour spout to and pull it part way out of said shell.

9. A carton according to claim 8, wherein said pour spout center section includes a recess in an upper edge thereof to facilitate grasping of the pour spout by a finger.

10. A carton according to claim 8, wherein said pour spout side sections each includes a projection extending upwardly from an outer corner thereof for engagement with said shell one minor side wall panel to prevent said pour spout from accidentally being pulled too far out of said shell.
