Paperboard can with an integrated lid having a hinge on the lid
View Patent ↗A substantially paperboard container for releasably dispensing contents contained therein is convertible from a substantially sealed orientation to a substantially open, dispensing orientation and back to the substantially sealed orientation. The paperboard container comprises a tubular container member, a bottom member and a top member, with the top member being telescopically received within the container member to seal the top member to the container. The top member is pivotable about the hinge portion and is pivotable to the sealed orientation to substantially reseal the container member. The lid is fabricated in whole or in part, from plastic material.
1. A container for releasably dispensing contents contained therein, the container being convertible from a substantially sealed orientation to a substantially open, dispensing orientation and back to the substantially sealed orientation, the container comprising:
a paperboard tubular body having an upper edge defining an upper opening;
a lid, including a substantially planar lid panel member having a peripheral edge region, the lid panel member being operably configured to extend across at least a portion of the upper opening;
the lid further including a band operably connected to the lid panel member along the peripheral edge region thereof,
the band extending generally at right angles to the lid panel;
at least portions of the band being juxtaposed and affixed to the tubular body along at least a portion of the tubular body proximate the upper edge thereof;
the lid having a fixed back portion for maintenance in a position juxtaposing the band to the interior of the tubular body at its upper edge, a hinge portion extending completely across the lid, and a movable front portion, pivotable at said hinge portion, between a closed position adjacent the upper edge of said tubular body and an open position enabling access to an interior region of the tubular body;
a container bottom opposite said lid,
the lid being fabricated primarily from a plastic material; and
wherein the lid comprises means for enabling the lid to be fixedly yet releasably positioned in a stable, open, raised position, subsequent to opening of the container and pivoting of the movable front portion of the lid up to a predetermined position, said means comprising at least a section of the fixed back portio of the lid being operably disposed to interfere with and positively engage a section of the movable front portion when the movable front portion has been moved to an upright open position, relative to the fixed back portion;
wherein the means for enabling the releasable, fixed positioning of the lid in a stable, open, raised position, subsequent to opening of the container and pivoting the movable front portion of the lid up to a predetermined position, comprise:
at least one retaining ridge, operably emanating inwardly from an inside surface of the band, disposed within the fixed back portion of the lid; and
an outwardly extending lip portion, operably disposed on the movable portion of the lid at least adjacent the retaining ridge, said lip portion configured to interferingly engage with the at least one retaining ridge, when the movable portion of the lid is raised to an open position, to enable the at least one retaining ridge to hold the movable portion of the lid in said stable, releasable, raised position.
2. The container according to claim 1 , wherein the lid is fabricated from at least one of the following materials: polystyrene, polypropylene, LDPE, HDPE or other polymers.
3. The container according to claim 1 , further comprising at least one reinforcing rib, extending from an inside surface of the band, inwardly and downwardly to an upper surface of the lid panel, for providing structural reinforcement of the band.
4. The container according to claim 1 , further comprising at least one circumferentially extending ridge, emanating from an outside surface of the band, for providing frictional engagement between the band and the inside surface of the upper end of the tubular body, upon insertion of the lid into the tubular body.
5. The container according to claim 1 , further comprising a membrane extending across the upper opening of the tubular body portion, under the lid panel, and substantially independent of the lid portion.
6. The container according to claim 5 , wherein the membrane is positioned on the top edge of the upper opening of the tubular body portion, below said lid.
7. The container according to claim 6 , wherein the membrane is inserted into and affixed to the inside surfaces of the upper opening of the tubular body portion.
8. The container according to claim 1 , wherein the lid panel is plug-shaped, so as to extend into the upper opening of the tubular body portion, when the movable front portion of the lid is in its closed position.
9. The container according to claim 1 , wherein the bottom comprises a bottom panel inserted into and adhered to inside surfaces of a bottom end region of the tubular body portion.
10. The container according to claim 1 , wherein the lid is monolithically formed from a single piece of plastic material.
11. The container according to claim 10 , wherein the lid is formed by injecting lid material into a mold.
12. The container according to claim 1 , further comprising a gripping tab emanating from a portion of the surrounding band adjacent the movable front portion, operably configured for the facilitated manual opening of the lid.
13. The container according to claim 1 wherein the lid further includes a lip emanating outwardly from an upper edge region of the band, around the substantial entire circumference of the band.
14. The container according to claim 13 wherein said lip rests on the upper edge of the tubular body of the container upon insertion of the lid into the tubular body, to assist in maintaining the lid in a secured position inside the tubular body.
15. The container according to claim 1 wherein the band of the lid includes a beveled portion at its lower edge, to facilitate insertion of the lid into the tubular body of the container.
16. A container for releasably dispensing contents contained therein, the container being convertible from a substantially sealed orientation to a substantially open, dispensing orientation and back to the substantially sealed orientation, the container comprising:
a paperboard tubular body having an upper edge defining an upper opening;
a lid, including a substantially planar lid panel member having a peripheral edge region, the lid panel member being operably configured to extend across at least a portion of the upper opening;
the lid further including a band operably connected to the lid panel member along the peripheral edge region thereof,
the band extending generally at right angles to the lid panel;
at least portions of the band being juxtaposed and affixed to the tubular body along at least a portion of the tubular body proximate the upper edge thereof;
the lid having a fixed back portion for maintaining the lid in a position juxtaposing the band to the interior of the tubular body at its upper edge, a hinge portion extending completely across the lid, and a movable front portion, pivotable at said hinge portion, between a dosed position adjacent the upper edge of said tubular body and an open position enabling access to an interior region of the tubular body;
a container bottom opposite said lid,
the lid being fabricated primarily from a plastic material; and
wherein the lid comprises means for enabling the lid to be fixedly yet releasably positioned in a stable, open, raised position, subsequent to opening of the container and pivoting of the movable front portion of the lid up to a predetermined position, said means comprising at least a section of the fixed back portion of the lid being operably disposed to interfere with and positively engage a section of the movable front portion when the movable front portion has been moved to an upright open position, relative to the fixed back portion; and
at least one reinforcing rib, extending from an inside surface of the band, inwardly and downwardly to an upper surface of the lid panel, for providing structural reinforcement of the band.
