Patent Application
20190344933
The present invention relates generally to a container closure having a hinged configuration that allows the closure to remain coupled to a container after the closure is opened. Specifically, whereas traditional closure plug designs are configured to permanently detach from the container after being opened, the design and configuration of the closure having a hinged configuration illustrated and described herein allows a closure to remain coupled to the container after being opened. As a result, there is a decreased likelihood that the closure may be littered.
In one embodiment a closure is centered about a vertical axis. The closure comprises a generally circular top panel having an upper surface, a lower surface and an outer periphery. A skirt extends generally perpendicularly downward from the outer periphery of the top panel. A thread is formed about an inner surface of the skirt.
In one embodiment, a closure includes an attachment band that is coupled to the container, and an indicator section that maintains a connection between the attachment band and the closure. When a user opens the closure, the frangible connections in the indicator section are broken, thereby allowing the upper portion of closure to be removed from the container inlet. After the closure is opened the indicator section maintains a connection between the attachment band and the rest of closure. The indicator section includes an attachment channel along which several frangible connections are aligned. The an attachment channel includes at least one bridge connection that remains unbroken after the frangible connections are broken.
In several embodiments, the attachment channel includes two attachment channels. A first attachment channel encircles the periphery of the indicator section, and a second attachment channel extends generally parallel to the primary channel. The first channel includes two bridge connections near either end of the second channel. The second channel covers a subset of the periphery of the indicator section, such as 45 degrees. In one embodiment, the first channel is above the second channel when the container is in an upright orientation. In another embodiment, the first channel is below the second channel when the container is in an upright orientation. In another embodiment, the first channel and the second channel are connected by a diagonal channel.
In one embodiment, the attachment channel encircles the periphery of the indicator section with a helical profile. As a result, the attachment channel covers more than 360 degrees of arc, for example 380-400 degrees of arc. In this example, there are 20-40 degrees of arc with vertical overlap. The vertical distance between the two ends of the attachment channel enable that portion of the indicator section to remain coupled even after the frangible connections are broken, and as a result the closure body remains coupled to the container even after the closure is opened.
In one embodiment, the attachment channel encircles the periphery of the indicator section. The attachment channel includes a plurality of frangible connections that are broken when the closure is opened. The attachment channel further includes two bridge connections, which are larger than the frangible connections and therefore remain unbroken when the frangible connections are broken.
This application will become more fully understood from the following detailed description, taken in conjunction with the accompanying figures, wherein like reference numerals refer to like elements in which:
Before turning to the figures, which illustrate the exemplary embodiments in detail, it should be understood that the present application is not limited to the details or methodology set forth in the description or illustrated in the figures. It should also be understood that the terminology is for the purpose of description only and should not be regarded as limiting.
Turning to
Skirt 20 is generally annular in cross-section and is substantially perpendicular to the plane defined by top panel 12. As shown in
Located along the inner surface of the skirt 20 is a container engagement structure configured to interact with a corresponding closure engagement structure located on the neck 102 of the container 100 to which closure 10 is to be sealing applied. As shown in
In some embodiments, closure 10 may further include a tamper evidencing structure configured to provide indication to a user that the initial sealing engagement between closure 10 and the container 100 has been disrupted as a result of the closure 10 being partially or entirely opened. As shown in
In one or more embodiments, attachment channel 42 includes frangible connections 48, linear openings 54 and one or more hinge bridges 56. Frangible connections 48 each have a width that is less than hinge bridges 56. As a result, hinge bridges 56 are sturdier and more resistant to breaking from torque when closure 10 is being removed from container 100.
As shown in
When the container 100 that closure 10 is coupled to is oriented in a typical upright position, top panel 12 is substantially horizontal to a ground surface and sidewalls 20 are generally vertical with respect to the ground. The two attachment channels 42 each include one or more of a plurality of frangible connections 48 that may be broken when closure 10 is removably uncoupled from the container 100. Among the two attachment channels 42 in the embodiment shown in
In one embodiment, top channel 44 includes a plurality of frangible connections 48 and two hinge bridges 56. Hinge bridges 56 are located approximately 30 degrees of arc from each other from the perspective of center axis 80 of closure 10. Hinge bridges 56 delimit attachment channel 42 into shorter channel 68, which connects hinge bridges 56 via the relatively shorter connecting route, and longer channel 66, which connects hinge bridges 56 by circumferentially encircling closure 10 via the relatively longer connecting route. Frangible connections 48 are disposed periodically throughout top channel 44, such as approximately every 20 degrees of arc from the perspective of center axis 80 of closure 10. A majority of frangible connections 48 are located in longer channel 66. Shorter channel 68 includes one frangible connection 48 in the embodiment of
In use, closure 10 is secured to a container and has a closed configuration 60 (shown in
Hinge bridges 56 are sturdier than frangible connections 48 and therefore less likely to break when closure 10 is being opened. As a result, often hinge bridges 56 remain unbroken and therefore upper portion 8 of closure 10, which includes top panel 12 and sidewall 20, remains coupled to attachment band 30 via hinge bridges 56. At this point, closure 10 has an open configuration 64 in which upper portion 8 is positionable to uncover the inlet of the container 100, and as a result the contents of the container 100 (e.g., water) may be consumed, removed, etc.
Subsequent to a user removing the contents of the container 100, upper portion 8 of closure 10 may be re-coupled to the inlet of the container 100. Sidewall 20 is positioned above container inlet 102 and rotated to engage container engagement structure 26 with the outer surface of the container inlet 102 (e.g., by rotating sidewall clockwise from a perspective above top panel 12).
The embodiment in
In another embodiment (not shown), one end of bottom channel 46 circumferentially extends to a point that is vertically aligned with the intersection between hinge bridge 56 and longer channel 66. In yet another embodiment (not shown), one end of bottom channel 46 circumferentially extends to a point that is vertically aligned with the intersection between hinge bridge 56 and shorter channel 68. In yet another embodiment (not shown), one end of bottom channel 46 extends to a point that is vertically aligned with hinge bridge 56. In one or more other embodiments, ends of bottom channel 46 may include a combination of one or more dispositions as described in this disclosure.

Subsequent to upper portion 8 being removed from container inlet, a majority and/or all of frangible connections 58 break, leaving sidewall 20 connected to attachment band 30 via connecting strand 57 (best shown in
