Locking closure for a container.
Packages of liquid are commonly moved in commerce. Packages for liquids often comprise a container and a closure engaged with the container. Threaded closures are commonly used to close containers. Prior to shipment, a threaded closure is engaged with a container by a machine that screws the closure onto the open end of the container. During transport from the filling location to the user's home, packages for liquids are often subjected to vibrations and impacts that can cause the threads of the closure to back off from the position in which the closure is sealingly engaged with the container. A problem associated with the threads of the closure backing off is that the user may unintentionally open the package since little force is required to unscrew the closure once the closure is not sealingly engaged with the container. Another problem associated with the threads of the closure backing off is that the package may leak, especially if the package is tipped over or inverted. With these limitations in mind, there is a continuing unaddressed need for a package having a closure system in which the closure is restrained from unintentional opening or backing off during transport.
A package (10) comprising: a closure (20) engaged with a container (30), wherein said closure comprises: a threaded collar (40) and a peripheral wall (50) extending from said threaded collar, wherein said peripheral wall extends around a longitudinal axis (L) and has an engagement rotation direction (E) in which said threaded collar engages with said container and a disengagement rotation direction (D) in which said thread collar disengages with said container; a tab (60) outboard of and spaced apart from said peripheral wall and connected to said peripheral wall by a deformable first arm (70) extending from a first arm attachment location (80) on said peripheral wall to said tab and deformable second arm (90) extending from a second arm attachment location (100) on said peripheral wall to said tab, wherein said second arm attachment location is radially offset from said first arm attachment location by from about 2 degrees to about 30 degrees in the engagement rotation direction, wherein said first arm attachment location is radially offset from said tab by from about 0.5 degrees to about 20 degrees in the engagement rotation direction, wherein said tab has a tab width (W) orthogonal to said longitudinal axis; wherein said container comprises; an open end (110) about said longitudinal axis; and an abutment (120) projecting above said open end and outboard of said open end and spaced apart from said peripheral wall by a clearance distance (C), wherein said clearance distance is greater than or equal to said tab width, and wherein said tab is abutted against said abutment.
A perspective view of a package 10 is shown in
The closure 20 comprises a tab 60 outboard of and spaced apart from the peripheral wall and connected to the peripheral wall by a deformable first arm 70 extending from a first arm attachment location 80 on the peripheral wall to the tab. The closure 20 further comprises a deformable second arm 90 extending from a second arm attachment location 100 on the peripheral wall 50 to the tab 60. The second arm attachment location 100 can be radially offset from the first arm attachment location 80 by from about 2 degrees to about 30 degrees in the engagement rotation direction E. The first arm attachment location 80 can be radially offset from the tab 60 by from about 0.5 degrees to about 20 degrees in the engagement rotation direction E. The tab has a tab width W orthogonal to the longitudinal axis. The tab width is a scalar quantity.
The container 30 comprises an open end 110 about the longitudinal axis L and an abutment 120 projecting above the open end and outboard of the open end and spaced apart from the peripheral wall by a clearance distance C. The clearance distance C is a scalar quantity. The clearance distance C can be greater than or equal to the tab width W. The tab 60 can be abutted against the abutment 120.
To unscrew the closure 20 from the container 30, the user presses the tab 60 towards the longitudinal axis to dislodge the tab 60 from the abutment 120. Then the user rotates the closure 20 in the disengagement rotation direction D to move the tab past the abutment 120. Optionally, the closure 20 comprises two the tabs 60 positioned radially opposite one another about the longitudinal axis L and the container comprises two the abutments 120 positioned radially opposite one another about the longitudinal axis L. The process of opening the package 10 process comprises the steps of pressing the tabs 60 towards the longitudinal axis L to dislodge the tabs 60 from the abutments 120. Then the user can rotate the closure 20 in the disengagement rotation direction D to move the tabs 60 past the abutments 120. The tab 60 or tabs 60 can have a first position abutting the abutment 120 or abutments 120 and a second position in which the tab 60 or tabs 60 are inboard of the abutment 120 or abutments 120 and rotatable in said disengagement rotation direction D past the abutment 120 or abutments 120.
The tab 60 or tabs 60 in combination with the abutment 120 or abutments 120 can help to resist backing off of the closure. The deformable first arm 70 and deformable second arm 90 can provide for flexible structures that can be deformed, optionally elastically deformed, by the user pushing on the tab 60 or tabs 60. The user can push the tab 60 or tabs 60 in far enough so that the tab 60 or tabs 60 can rotationally move past the abutment 120 or abutments 120 so that the closure 20 can be removed from the container 30.
The deformable first arm 70 and deformable second arm 90 can extend from away from the peripheral wall 50 at the first arm attachment location 80 and second arm attachment location 100 in a direction, respectively, in a direction about the longitudinal axis L in the disengagement rotation direction D.
The second arm attachment location can be radially offset from said first arm attachment location by from about 2 degrees to about 20 degrees, optionally from about 2 degrees to about 15 degrees, optionally from about 2 degrees to about 10 degrees, in the engagement rotation direction. The first arm attachment location can be radially offset from said tab by from about 0.5 degrees to about 15 degrees, optionally from about 0.5 degrees to about 10 degrees, from about 0.5 degrees to about 5 degrees, from about 2 degrees to about 20 degrees, from about 2 degrees to about 15 degrees, from about 2 degrees to about 10 degrees, in the engagement rotation direction.
The open end 110 can comprise a spout fitment 130, optionally a drain back spout fitment 150, engaged with the container body 140. The spout fitment can comprise a spout 180 that projects into the closure 20. A portion of the spout 180 can be positioned between the peripheral wall 50 and the longitudinal axis L.
The threaded collar 40 can be continuous about the longitudinal axis L. Optionally, the threaded collar 40 can have one or more slots positioned around the longitudinal axis L.
The threaded collar 40, peripheral wall 50, tab 60, deformable first arm 70, and said deformable second arm 90 can be unitary with one another and comprised of plastic, optionally a thermoset plastic.
Each tab 60 can have an engaged portion abutting the abutment 120. The engaged portion can have a height H. The threaded collar 40 can comprise threads having a pitch P. The pitch P can be at least twice the height H. In such an arrangement, a 180 degree rotation in the disengagement direction D can move the closure 20 along the longitudinal axis L such that the tab 60 does not collide with an abutment 120 on the other side of the container 30.

Instead, unless otherwise specified, each such dimension is intended to mean both the recited value and a functionally equivalent range surrounding that value.
