Abstract

A container comprising a carton having a freshness-preserving liner disposed therein wherein superimposed apertures having substantially wholly die-cut lineaments are opened in said carton and said liner substantially simultaneously upon opening of the container.

Claims

1. A container comprising:

a. a carton having an aperture in one surface thereof, b. a closure adapted to close said aperture in said carton, said closure being formed of freshness-preserving barrier material, c. a product-containing liner comprising freshness-preserving barrier material, said liner having a die-cut portion whOlly removed therefrom forming a dispensing port in one wall thereof, said dispensing port being smaller than said aperture, said liner being received within said carton with the area of said liner bordering said dispensing port being juxtaposed the inwardly facing area of said closure, d. liner restraining means securing said liner within said carton, and e. an adhesive sealant of freshness-preserving barrier material bridging said border area of said liner and said inwardly facing area of said closure forming an interconnection substantially as freshness-preserving as said freshnesspreserving barrier material of said liner and said closure, said sealant being selectively adhesive rendering said closure partable from said liner without tearing the barrier material of either said liner or said closure upon initially opening said closure.

2. The container of claim 1 wherein said closure comprises transparent barrier material in its area coincident with said dispensing port of said liner.

3. A container comprising:

a. a carton having an aperture in one surface thereof;

b. a closure adapted to close said aperture in said carton, said closure having an inwardly facing securement surface;

c. a sealed product-containing liner comprising laminated material having a plurality of plies including a ply of freshness-preserving barrier material, said liner further comprising a dispensing port forming portion and a residual portion, said port forming portion being defined by a die-cut perforate line of weakening, said liner being received within said carton with said line of weakening contiguous said securement surface;

d. liner restraining means interconnecting said residual portion of the liner with said carton; and

, e. a bridging adhesive sealant also comprising freshness-preserving barrier material directly overlying said line of weakening and serving to interconnect said securement surface of said closure with the areas of said residual and port forming portions of said liner bordering said line of weakening, said sealant bridging the entirety of said line of weakening and thereby rendering it substantially as freshness-preserving as uncut portions of said liner, said sealant being selectively adhesive rendering said securement surface partable from said residual portion, and said sealant being sufficiently adhesive between said dispensing port forming portion of said liner and said securement surface to cause separation along said line of weakening substantially simultaneously as said securement surface parts from said border area of said residual portion upon opening of said closure, said laminated material having sufficient tear strength to separate said dispensing port forming portion from said residual portion without tearing the barrier ply of said residual portion of said liner as said closure is initially opened whereby said dispensing port thus formed in said liner has a substantially unimpaired plan view die-cut lineament.

4. A container comprising:

a. a carton having an aperture in one surface thereof;

b. a closure adapted to close said aperture in said carton, said closure having an inwardly facing securement surface;

c. a sealed product-containing liner comprising freshness-preserving barrier material, said liner further comprising a dispensing port forming portion and a residual portion, said port forming portion being defined by a single die-cut through said liner material, said liner being received within said carton with said single die-cut contiguous said securement surface;

d. liner restraining means interconnecting said residual portion of the liner with said carton; and

, e. a bridging adhesive sealant also comprising freshness-preserving barrier material directly overlying said single die-cut and serving to interconnect said securement surface of said closure with the areas of said residual and port forming portions of said liner bordering said single die-cut, said sealant bridging the entirety of said single die-cut and thereby rendering it substantially as freshness-preserving as uncut portions of said liner, said sealant being selectively adhesive rendering said securement surface partable from said residual portion, and said sealant being sufficiently adhesive between said dispensing port forming portion of said liner and said securement surface to cause separation along said single die-cut substantially simultaneously as said securement surface parts from said border area of said residual portion upon opening of said closure.

5. The container of claim 4 wherein said single die-cut is endless whereby said dispensing port forming portion of said liner is wholly die-cut from said residual portion of said liner whereby it forms a dispensing port having a wholly die-cut perimeter upon initial opening of said closure.

6. A container comprising:

a. a carton having an aperture in one surface thereof;

b. a closure adapted to close said aperture in said carton, said closure having an inwardly facing securement surface;

c. a sealed product-containing liner comprising freshness-preserving barrier material, said liner comprising a dispensing port forming portion and a residual portion, said port forming portion being defined by a die-cut perforate line of weakening, said liner being received within said carton with said line of weakening contiguous said securement surface;

d. liner restraining means interconnecting said residual portion of the liner with said carton; and

, e. a bridging adhesive sealant also comprising freshness-preserving barrier material directly overlying said line of weakening and serving to interconnect said securement surface of said closure with the areas of said residual and port forming portions of said liner bordering said line of weakening, said sealant bridging the entirety of said line of weakening and thereby rendering it substantially as freshness-preserving as uncut portions of said liner, said adhesive sealant being selectively adhesive so that said securement surface is peelable from said area of said residual portion of said liner bordering said line of weakening during initial opening of said container and said sealant being sufficiently adhesive to interconnect said dispensing port forming portion of said liner with said securement surface of said closure strongly enough to separate said line of weakening substantially simultaneously as said securement surface parts from said border area of said residual portion during said initial opening of said closure.

7. The container of claim 6 wherein said closure is hingedly attached to said carton, said closure being configured to open outwardly only.

8. The container of claim 7 having a repeatably latchable-unlatchable means adapted to retain said closure in the closed position upon closing until unlatched and opened.

9. The container of claim 8 wherein one edge of said aperture in said carton is formed by folding a flap inwardly until a portion of its inwardly facing surface is juxtaposed with an inwardly facing surface of said carton, said flap having a plurality of transverse score lines formed therein which extend generally parallel to its proximal edge, said score lines adapted for forming said flap into a transversely extending lip when said flap is folded inwardly, said closure having a rounded nose adapted to co-act with said lip whereby said closure is releasably latchable and said aperture can be repeatedly opened and closed.

10. The container of claim 9 wherein a securement portion of said inwardly folded flap extending from adjacent its distal edge is adhesively secured to said inwardly facing surface of said carton.

11. The container of claim 10 wherein said flap is a minor flap of said carton, said minor flap being narrower than the side of the carton to which it is hinged and said aperture is disposed in the top panel of said carton.

12. The container of claim 6 wherein said dispensing port is formed In a seamless portion of said liner.

13. The container of claim 12 wherein said liner restraining means comprises bands of adhesive intermediate the upper perimeter of said residual portion of said liner and said carton whereby said residual portion of said liner and said carton are maintained substantially spaced fixed relative to each other after being so secured.
