Abstract

A dispenser has a bottle (2) and a closure (3) for the bottle (2). The closure (3) has abase (4) forming a dispensing outlet (6) and a flip-cap for openably closing the dispensing outlet (6). The base (4) is attached on the bottle (2). The dispenser (1) further having a hinge (7) which interconnects the flip-cap and the base (4) for swiveling the flip-cap relative to the base (4) between a closed position, in which the flip-cap closes the outlet (6), and an open position in which the outlet (6) is open. The hinge (7) forms a swivel axis. The closure (3) forms a first end (18, 19) in a direction toward the flip-cap and a second end (18, 19) in a direction toward the base (4). The closure (3) in an area between the hinge-level plane and the second end (18, 19) forms an outer surface circumferentially around the longitudinal axis which is at least partly provided by an outer surface of the base (4) and an outer surface of the flip-cap.

First claim

What is claimed is:

1. A dispenser for a flowable substance extending along a longitudinal axis, the dispenser comprising:
a bottle and
a closure for the bottle;
the closure comprising a base forming a dispensing outlet and a flip-cap for openably closing the dispensing outlet;
the base being attached on the bottle;
the dispenser further comprising a hinge which interconnects the flip-cap and the base for swiveling the flip-cap relative to the base between a closed position, in which the flip-cap closes the outlet, and an open position in which the outlet is open;
the hinge forming a swivel axis in a hinge-level plane that is arranged perpendicular to the longitudinal axis;
wherein the closure forms a first end in a direction toward the flip-cap and a second end in a direction toward the base;
wherein the closure in an area between the hinge-level plane and the second end forms an outer surface circumferentially around the longitudinal axis which is at least partly provided by an outer surface of the base and an outer surface of the flip-cap;
wherein in the closed position a first label is attached on said outer closure surface, with the first label covering at least a portion of the outer base surface and at least a portion of the outer flip-cap surface and thereby retaining the flip-cap against swiveling toward the open position;
wherein the flip-cap and the base in combination form a parting line in the closed position of the dispenser, and wherein the parting line extends at least in part offset from the hinge-level plane, and wherein the offset is in a direction from the hinge toward the second end of the closure,
wherein the parting line is defined on a parting-level plane that is inclined with respect to the longitudinal axis; and
wherein the hinge is configured to urge the flip-cap in either a pre-closed or an open position, wherein the pre-closed position is between the closed and the open position and closer to the closed position, and wherein in the pre-closed position the flip-cap and the remainder of the dispenser are visibly misaligned.

2. The dispenser of claim 1 , wherein the flip-cap is formed by a cup-shaped shell having a bottom wall and a circumferential side wall extending from the bottom wall.

3. The dispenser of claim 2 , wherein the hinge is connected to the side wall of the flip-cap.

4. The dispenser of claim 2 , wherein a first retention structure is provided in or at the side wall for cooperation with a second retention structure provided on the base.

5. The dispenser of claim 1 , wherein the first label extends at least partially circumferentially around the longitudinal axis.

6. The dispenser of claim 5 , wherein the first label forms a pull-strap for facilitating the first label to be removed by a user.

7. The dispenser of claim 1 , further comprising a second label bonded on the bottle.

8. The dispenser of claim 7 , wherein the second label is additionally bonded to the base.

9. The dispenser of claim 8 , wherein the first and second label are connected via a predetermined breaking zone allowing for the first label to be removed from the dispenser without removing the second label.

10. The dispenser of claim 1 , wherein the closure between the hinge-level plane and the second end of the closure forms a cylindrical surface.

11. The dispenser of claim 1 , comprising the flowable substance, wherein the flowable substance is a dental bonding dental material.

12. A dispenser for a flowable substance extending along a longitudinal axis, the dispenser comprising:
a bottle and
a closure for the bottle;
the closure comprising a base forming a dispensing outlet and a flip-cap for openably closing the dispensing outlet;
the base being attached on the bottle;
the dispenser further comprising a hinge which interconnects the flip-cap and the base for swiveling the flip-cap relative to the base between a closed position, in which the flip-cap closes the outlet, and an open position in which the outlet is open;
the hinge forming a swivel axis in a hinge-level plane that is arranged perpendicular to the longitudinal axis;
wherein the closure forms a first end in a direction toward the flip-cap and a second end in a direction toward the base;
wherein the closure in an area between the hinge-level plane and the second end forms an outer surface circumferentially around the longitudinal axis which is at least partly provided by an outer surface of the base and an outer surface of the flip-cap;
wherein in the closed position a first label is attached on said outer closure surface, with the first label covering at least a portion of the outer base surface and at least a portion of the outer flip-cap surface and thereby retaining the flip-cap against swiveling toward the open position;
wherein the flip-cap and the base in combination form a parting line in the closed position of the dispenser, and wherein the parting line extends at least in part offset from the hinge-level plane, and wherein the offset is in a direction from the hinge toward the second end of the closure,
wherein the parting line is defined on a parting-level plane that is inclined with respect to the longitudinal axis;
further comprising a second label bonded on the bottle, wherein the second label is additionally bonded to the base.
