Abstract

A protrusion on a container neck is provided. The protrusion is configured to interface with hinged, tethered closures to bias the body of the closure away from the container neck.

First claim

What is claimed is:

1. A container comprising:
a body defining a storage compartment;
a container neck coupled to the body, the container neck extending along a longitudinal axis between the body and an opening;
a thread extending helically outward from the container neck, the thread configured to detachably engage with a closure affixed to the container neck, wherein the closure is distinct from the container, the closure configured to actuate between a closed configuration in which the closure encloses the opening and an open configuration in which a tab of the closure interfaces with the container neck to bias a body of the closure away from the container neck;
an A-bead extending radially away from the container neck, the A-bead configured to engage with a retention band of the closure to bias the retention band to remain coupled to the container neck after the closure has been opened; and
a protrusion extending upward from the A-bead, the protrusion configured to engage the tab of the closure to bias the body of the closure away from the container neck,
wherein the A-bead defines an upper surface that extends from a top of the A-bead to the protrusion, and wherein the protrusion defines an upper surface that faces upward and an outer surface that faces away from the axis, the outer surface of the protrusion and the upper surface of the protrusion intersecting at a corner, the corner being below the top of the A-bead.

2. The container of claim 1 , wherein the outer surface of the protrusion defines a first angle with the upper surface of the A-bead, and wherein the first angle is between 120 degrees and 150 degrees.

3. The container of claim 1 , wherein the tab of the closure is configured to interface with the corner when the protrusion is biasing the body of the closure away from the container neck.

4. The container of claim 1 , wherein:
the thread defines a first diameter that is a maximum diameter of the thread with respect to the axis; and
the outer surface of the protrusion defining a second diameter that is less than or equal to the first diameter.

5. The container of claim 4 , wherein the second diameter is less than the first diameter.

6. The container of claim 1 , wherein the protrusion is affixed to the A-bead via an adhesive.

7. The container of claim 1 , wherein the protrusion and the A-bead are molded contemporaneously.

8. The container of claim 1 , the upper surface of the A-bead extends between the protrusion and the container neck.

9. The container of claim 1 , wherein the A-bead defines an outer surface that extends away from the longitudinal axis, and wherein the upper surface of the A-bead extends between the protrusion and the outer surface of the A-bead.

10. The container of claim 1 , the outer surface of the protrusion extending a first height from the A-bead, wherein the top of the A-bead is a second height above the corner of the protrusion, and wherein the second height is less than the first height.

11. A container comprising:
a body;
a container neck coupled to the body, the container neck extending along a longitudinal axis between the body and an opening;
a thread extending helically outward from the container neck, an outermost portion of the thread defining a T-diameter that is a maximum diameter of the thread with respect to the axis, the thread configured to detachably engage with a closure affixed to the container neck, wherein the closure is distinct from the container, the closure configured to actuate between a closed configuration in which the closure encloses the opening and an open configuration in which a tab of the closure interfaces with the container neck to bias a body of the closure away from the container neck;
an A-bead extending radially away from the container neck, the A-bead configured to engage with a retention band of the closure to bias the retention band to remain coupled to the container neck after the closure has been opened; and
a protrusion extending upward from the A-bead, the protrusion defining an outer surface defining a second diameter that is a maximum diameter of the protrusion with respect to the axis, wherein the second diameter is less than the T-diameter,
wherein the A-bead defines an upper surface that faces upward, and wherein the upper surface of the A-bead extends between the protrusion and the container neck, and wherein the A-bead defines an outer surface that extends away from the longitudinal axis, and wherein the upper surface of the A-bead extends between the protrusion and the outer surface of the A-bead.

12. The container of claim 11 , the protrusion defining an upper surface that faces upward and wherein the outer surface faces away from the axis, the outer surface of the protrusion and the upper surface of the protrusion intersecting at a corner, and wherein the tab of the closure is configured to interface with the corner when the protrusion is biasing the body of the closure away from the container neck.

13. A container comprising:
a body;
a container neck coupled to the body, the container neck extending along a longitudinal axis between the body and an opening;
a thread extending helically outward from the container neck, the thread configured to detachably engage with a closure affixed to the container neck, wherein the closure is distinct from the container, the closure configured to actuate between a closed configuration in which the closure encloses the opening and an open configuration in which a tab of the closure interfaces with the container neck to bias a body of the closure away from the container neck;
an A-bead extending radially away from the container neck, the A-bead configured to engage with a retention band of the closure to bias the retention band to remain coupled to the container neck after the closure has been opened, the A-bead defining an outer surface defining a first diameter that is a maximum diameter of the A-bead with respect to the axis; and
a protrusion extending upward from the A-bead, the protrusion defining an outer surface facing away from the axis, the outer surface of the protrusion defining a second diameter that is a maximum diameter of the protrusion from the axis, wherein the second diameter is less than the first diameter,
wherein the A-bead defines an upper surface that extends from a top of the A-bead to the protrusion, and wherein the protrusion defines an upper surface that faces upward, the outer surface of the protrusion and the upper surface of the protrusion intersecting at a corner, the corner being below the top of the A-bead.

14. The container of claim 13 , wherein the outer surface of the protrusion defines a first angle with the upper surface of the A-bead, and wherein the first angle is between 120 degrees and 150 degrees.

15. The container of claim 13 , wherein the tab of the closure is configured to interface with the corner when the protrusion is biasing the body of the closure away from the container neck.
