Abstract

A can ( 1 ) having a spout that can, after opening, be securely resealed and can be opened and closed with an easy operation. The can ( 1 ) has a spout ( 3 ) that is opened by lifting and pulling a pull-ring ( 6 ) fixed on a top wall ( 2 ) of a can body ( 1 a ) with a rivet ( 5 ) to bend a sealing tongue portion ( 4 ) toward the inside of the can. Inside the top wall ( 2 ) and away from the spout ( 3 ), an internal sealing member ( 7 ) having a fan shape with its pivot mounted to the rivet and a size capable of sealing the spout ( 3 ) is disposed so as to be fixed to the rivet ( 5 ). After opening the spout ( 3 ), by rotating the pull-ring ( 6 ) around the rivet ( 5 ), the internal sealing member ( 7 ) is also rotated at the same time. As an interlocking mechanism therefor, the rivet ( 5 ) is rotatably supported by the top wall ( 2 ), and a base end of the pull-ring ( 6 ) and the pivot of the internal sealing member ( 7 ) are fixed to the rivet ( 5 ), respectively.

Claims (23)

1. A can comprising:

a top wall with a dispensing opening that is normally closed by a sealing tongue portion;

a pull-ring for opening the dispensing opening, said pull-ring being fixed to a projection formed on the top wall of the can, wherein the dispensing opening can be opened by lifting and pulling the pull-ring to bend the sealing tongue portion toward an inside of the can;

an internal sealing member having a size capable of sealing the dispensing opening, the internal sealing member being fixed to the projection and disposed on a position inside of the top wall and away from the dispensing opening;

and an interlocking mechanism for rotating the internal sealing member at the time when the pull-ring is rotated around the projection after the dispensing opening is opened by bending the sealing tongue portion toward the inside of the can, wherein said interlocking mechanism is a thin-walled portion having a form of a closed curve that encircles the projection and is torn when the dispensing opening is initially opened by lifting and pulling the pull-ring.

2. The can according to claim 1 , wherein, on an area of said top wall between the thin-walled portion and the sealing tongue portion, at least one selected from a convex portion extending toward an outer side of the top wall and a concave portion extending toward an inner side of the top wall is provided.

3. The can according to claim 1 , wherein said internal sealing member is formed in a fan shape with a pivot mounted on said projection.

4. The can according to claim 1 , wherein said internal sealing member is made of substantially the same material as a material of a body of the can.

5. The can according to claim 1 , wherein a plurality of convex portions are formed in an area of said top wall between the thin-walled portion and the sealing tongue portion, the convex portions extend outwardly of the top wall.

6. The can according to claim 1 , wherein a plurality of concave portions are formed in an area of said top wall between the thin-walled portion and the sealing tongue portion, the concave portions extend inwardly of the top wall.

7. The can according to claim 1 , wherein the internal sealing member includes a projection that is received in the projection formed in the top wall, and the projections extend through a hole formed in the pull-ring.

8. A can comprising:

a top wall with a dispensing opening that is normally closed by a sealing tongue portion;

an opening device for opening the dispensing opening, said opening device being fixed to a projection formed on the top wall of the can, wherein the dispensing opening can be opened by lifting and pulling the opening device so as to bend the sealing tongue portion toward an inside of the can;

an internal sealing member having a size capable of sealing the dispensing opening, the internal sealing member being fixed to the projection and disposed on a position inside of the top wall and away from the dispensing opening;

and an interlocking mechanism for rotating the internal sealing member at the time when the opening device is rotated around the projection after the dispensing opening is opened by bending the sealing tongue portion toward the inside of the can,

wherein said interlocking mechanism is a thin-walled portion having a form of a closed curve that encircles the projection and is torn when the dispensing opening is initially opened by lifting and pulling the opening device.

9. The can according to claim 8 , wherein, on an area of said top wall between the thin-walled portion and the sealing tongue portion, at least one selected from a convex portion extending toward an outer side of the top wall and a concave portion extending toward an inner side of the top wall is provided.

10. The can according to claim 8 , wherein said internal sealing member is formed in a fan shape with a pivot mounted on said projection.

11. The can according to claim 8 , wherein said internal sealing member is made of substantially the same material as a material of a body of the can.

12. The can according to claim 8 , wherein a plurality of convex portions are formed in an area of said top wall between the thin-walled portion and the sealing tongue portion, the convex portions extend outwardly of the top wall.

13. The can according to claim 8 , wherein a plurality of concave portions are formed in an area of said top wall between the thin-walled portion and the sealing tongue portion, the concave portions extend inwardly of the top wall.

14. The can according to claim 8 , wherein the internal sealing member includes a projection that is received in the projection of the top wall, and the projections extend through a hole formed in the pull-ring.
