The strip has a bottom weakness line formed by a plurality of bottom bridges connected to the tamper band and a top weakness line formed by a plurality of top bridges connected to the closure shell. The bridges are configured to be stretched and broken when the closure shell is moved from a first orientation to a second orientation. The hinge is positioned beneath a set of bridges located along the top weakness line.
Description
2 TETHERED PLASTIC SCREW STOPPER
TECHNICAL FIELD
10011 This invention relates.to a tethered plastic screw stopper.
BACKGROUND
19021 in the field of liquid packaging, it is very common to seal the aperture of a container with a stopper, often made from a plastic material. Such container is usually a plastic or glass bottle, but other materials may be used as well.
10031 The stopper has a tubular shape closed at. its top. edge by a top wall. The stopper comprises a .roof attached to a tamper shell through bridges. Bridges are distributed around the circumference of the roof and the tamper shall. The bridges may be made when molding the stopper or after through undergoing a cutting step during the manufacturing process.
10041 Usually the bottle neck includes outer fixation feature, such as thread(s) for screw type stopper or annular fixation rings tbr snap type stopper, to secure the stopper on the bottle neck, 10051 For screw type stoppers, the tamper shell comprises inner thread(s) arranged inside side walls. The bottle neck fixation feature may include outer thread(s).
Such combination of outer and inner thread(s) allows the stopper to be screwed on a bottle neck to seal it and unscrewed for bottle opening. A snap type stopper may include an inner annular area and the bottle neck fixation feature may include outer fixation ring, in order to slot in tbrce the stopper on the bottle neck. A snap type stopper may include a tamper shell with .a movable sealing roof from a closed position to .a partial opening position, and reversely. The. roof may be separated upon opening or may be connected to the tamper shell.
10061 in a bottle sealing position of the stopper, the tamper shell may be secured around the bottle neck through inner shell retaining features or through the retaining features diameter being smaller than a diameter of a tamper shell of the bottle neck.
10071 The roof may be removable. During bottle opening, the bridges lbrm a weakness line and may be torn apart from the roof, separating it from the bottle. The weakness line may be torn when user unscrews the tamper shell of the stopper or when user lifts the roof by tilting.
10081 There is a recycling risk with separable roof as consumers may not always screw or snap. back the roof onto the bottle neck once empty. The stopper may be thrown away as litter or put into the trash bin, or worse make its way into a landfill, which is not good in view of the environmental considerations.
10091 One solution includes linking the roof to the tamper shell secured on the bottle neck, so the roof stays attached to the bottle after bottle opening.
Such an attached stopper may be called a "tethered stopper."
100101 U.S. Patent No. 9,010,555 teaches a plastic screw stopper including a peripheral strip between a. tamper shell and a roof. Such peripheral strip is linked to the tamper shell through a bottom weakness line and to the roof through a top weakness line.
The bottom weakness. line and top weakness line are parallel- and extend across the periphery of the stopper in order to incorporate one or two hinges in elosc.
proximity to each other. When unscrewing the stopper the bottom weakness line and top weakness line tear apart, but the two hinges hold the roof on the tamper shell. The roof becomes Immovable and as capable- of toggling around the hinges beside of the stopper secured on the bottle neck.
100111 U.S. 8,490,805 teaches a plastic screw stopper comprises a helicoidal strip between a tamper shell and a roof Such helicoidal strip is obtained by cutting the tamper shell around the stopper. The outer wall of the tamper shell is placed, against a blade and the stopper is moved in rotation relative to the blade according to an angular stroke greater than an entire turn or more than 360. During rotation, the-stopper is being moved in an axial. movement relative to the blade. The cut line forms a helicoidal weakness line which remains attached at one end to the tamper shell and at its opposite end to the roof after opening.
100121 Other known art prior art systems include a tethered stopper comprising a spiral. strip. The spiral strip is made during the stopper molding so there is no cutting or slitting operations,. Other known prior art systems includes tethered -stoppers comprising two strips linking the closure shell to the tamper band secured on the bottle.
SUMMARY
100131 This invention is a tethered plastic screw stopper where its closure shell remains attached to its tamper band after the bottle is opened by use of a strip made into the plastic material of the stopper between the tamper band and the closure shell using a bottom weakness line and a top weakness line. Each strip remains connected to the tamper band secured on the bottle neck by a least a. bottom hinge managed into the bottom weakness line. The opposite ends, of melt strip are directly linked to the closure shell through a junction point.
I00l4] The stoppe,r further comprises a specific top weakness line where the junction point of the strip with. -the. closure shell is located over a bottom bridge located at the nearest from the bottom hinge(s), so called "nearest bottom bridge" on a side of the Setewing direttinn of therelosure 100151 Thus, the invention systematically allows the nearest bottom bridge to he broken due to the junction point location where the closure shell and the strip ends are upwardly moved the farthest from the tamper band during closure shell unscrewing motion. A force is applied on the -closest bridge due to the specific position of the junction point of the end of the strip.

Variations, modifications, and combinations may be made to the described embodiments without departing from the scope of the claims. All such variations, modifications, and combinations are included herein by the scope of this disclosure and the claims.
100261 This invention relates to a tethered plastic screw stopper 100 for closing a bottle neck 102. The. stopper 100 is integrally made of one plastic piece by a molding
4 fabrication step. Other parts or elements of the stopper 100 can be further created into the entire plastic piece through a cutting or slitting step.
100271 The. stopper 100 is a strew type and comprises inner fixation features, such as thread(s), designed. to cooperate with outer complementary fixation features Made on the bottle neck 102.
100281 In some embodiments, as illustrated in Figures 1 through 4, the screwing direction of the stopper 100 is typically clockwise and extends from right to left. The screwing orientation is represented as a directional arrow in Figures 1 through 4. The unscrewing direction of the stopper .100 oppositely extends relative to the screw direction, so counterclockwise from left to rights In other embodiments, the screwing direction can be designed counterclockwise.
100291 The stopper 100 comprises a closure shell 104 and underneath a tamper band 106. The. tamper band 106 and the closure shell 104 are separably linked together by way of a strip 108..
100301 In some embodiments, the stopper 100 includes one strip 108. In other embodiments, the stopper 100 includes two or more strips 108. For example, the stopper 100 includes two strips 108 positioned on opposite sides of the stopper I(X).
The two strips 108 can be positioned in a symmetrical Or asymmetrical layout.
100311 The strip 108 is separably connected to the closure 'shell. 104 through a plurality of top bridges 11.2 that ibrm a top weakness line 110. Similarly, the strip 1.08 is separably connected to the tamper hand 106 through a plurality of bottom bridges 116 that form a bottom weakness line 114.
100321 The bottom weakness line 114 comprises at least one hinge 118 configured to connect the strip 108 and the tamper band 106. In some embodiments, the bottom weakness line 114 comprises two hinges 118. where each hinge 118 connects a respective strip 108 to the tamper band 1%. The two hinges 118 can be spaced through a hole or. a less thick material managed into the tamper band 106 between the two hinges 118.
100331 The top bridges 112 and bottom bridges 116 are each configured to he stretched and ultimately broken when unscrewing the closure Shell 104. The top and bottom bridges 112, 116 are regularly or irregularly positioned around the perimeter of the top and bottom weakness lines 110, 114 respectively. However, at the location of the hinge(s) 1.18, the top and bottom bridges 112, 116 are not present 10034j Each strip 108 comprises an extremity at an end of the top weakness line.
110, linking the strip 108 with the closure shell 104 at a junction point 120.. For example, in the embodiment having two strips 108, there is a.junction point 1.20 at each end of the top weakness line 110, linking the extremity of each strip 108 to the closure shell 104.
100351 The top weakness line 110 is configured in order to firm an end 122 of the strip 108 positioned above a bottom bridge 116 located at the nearest to the hinge 118 on the left side of the hinge considering a clockwise screwing direction of the closure shell 104. When facing the stopper looking at the hinge(s) 118, if the screw direction is clockwise, then the junction point of the left strip relative to the hinge .118 is located over the nearest left bottom bridge 116 (denoted with parallel vertical lines in Figure 2).
10036] The end of the top weakness line located on the left of the hinge 118 for a clockwise screwing stopper is angularly located between - 40" to 40" relative to the -vertical axis of the bottom bridge 1.16 located at the nearest: from the hinge .1.18. In some embodiments, the hinge .118 is more .particularly located between - 20 to 20 relative to the vertical axis of the bottom bridge 116 located at the nearest from the hinge 11.8. For example, when looking at the hinge 118, the junction point 120 of the left strip 108. is angularly situated approximately 20 relative to the = left nearest bottom bridge 116. Such angular variation is shown in the drawings illustrated in dotted lines on Figures 3 and 4.
100371 in Some embodiments, the top weakness line 110 is asymmetric relative to the bottom weakness line .114 which is symmetric relative to a vertical plane crossing the diameter of the stopper 100. So when molding or further slitting. the stopper 100, the top weakness line 110 is angularly switched or turned offset in relation with the position of the hinge(s) 118 Of the bottom weakness line 114. Thus, one strip 108 (c.a.,. the left strip) in a clockwise screwing configuration, is shorter than the opposite strip 108 (e.g., the right strip). In other embodiments, such as Show in. Figure 3, the -bottom weakness line 114 is symmetric relative to a vertical plane crossing the diameter of the stopper 100 where the plane being shown by a fine continuous line.
100381 While various embodiments. of the invention have been described, it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible that are within the scope of this invention.
100271 The. stopper 100 is a strew type and comprises inner fixation features, such as thread(s), designed. to cooperate with outer complementary fixation features Made on the bottle neck 102.
100281 In some embodiments, as illustrated in Figures 1 through 4, the screwing direction of the stopper 100 is typically clockwise and extends from right to left. The screwing orientation is represented as a directional arrow in Figures 1 through 4. The unscrewing direction of the stopper .100 oppositely extends relative to the screw direction, so counterclockwise from left to rights In other embodiments, the screwing direction can be designed counterclockwise.
100291 The stopper 100 comprises a closure shell 104 and underneath a tamper band 106. The. tamper band 106 and the closure shell 104 are separably linked together by way of a strip 108..
100301 In some embodiments, the stopper 100 includes one strip 108. In other embodiments, the stopper 100 includes two or more strips 108. For example, the stopper 100 includes two strips 108 positioned on opposite sides of the stopper I(X).
The two strips 108 can be positioned in a symmetrical Or asymmetrical layout.
100311 The strip 108 is separably connected to the closure 'shell. 104 through a plurality of top bridges 11.2 that ibrm a top weakness line 110. Similarly, the strip 1.08 is separably connected to the tamper hand 106 through a plurality of bottom bridges 116 that form a bottom weakness line 114.
100321 The bottom weakness line 114 comprises at least one hinge 118 configured to connect the strip 108 and the tamper band 106. In some embodiments, the bottom weakness line 114 comprises two hinges 118. where each hinge 118 connects a respective strip 108 to the tamper band 1%. The two hinges 118 can be spaced through a hole or. a less thick material managed into the tamper band 106 between the two hinges 118.
100331 The top bridges 112 and bottom bridges 116 are each configured to he stretched and ultimately broken when unscrewing the closure Shell 104. The top and bottom bridges 112, 116 are regularly or irregularly positioned around the perimeter of the top and bottom weakness lines 110, 114 respectively. However, at the location of the hinge(s) 1.18, the top and bottom bridges 112, 116 are not present 10034j Each strip 108 comprises an extremity at an end of the top weakness line.
110, linking the strip 108 with the closure shell 104 at a junction point 120.. For example, in the embodiment having two strips 108, there is a.junction point 1.20 at each end of the top weakness line 110, linking the extremity of each strip 108 to the closure shell 104.
100351 The top weakness line 110 is configured in order to firm an end 122 of the strip 108 positioned above a bottom bridge 116 located at the nearest to the hinge 118 on the left side of the hinge considering a clockwise screwing direction of the closure shell 104. When facing the stopper looking at the hinge(s) 118, if the screw direction is clockwise, then the junction point of the left strip relative to the hinge .118 is located over the nearest left bottom bridge 116 (denoted with parallel vertical lines in Figure 2).
10036] The end of the top weakness line located on the left of the hinge 118 for a clockwise screwing stopper is angularly located between - 40" to 40" relative to the -vertical axis of the bottom bridge 1.16 located at the nearest: from the hinge .1.18. In some embodiments, the hinge .118 is more .particularly located between - 20 to 20 relative to the vertical axis of the bottom bridge 116 located at the nearest from the hinge 11.8. For example, when looking at the hinge 118, the junction point 120 of the left strip 108. is angularly situated approximately 20 relative to the = left nearest bottom bridge 116. Such angular variation is shown in the drawings illustrated in dotted lines on Figures 3 and 4.
100371 in Some embodiments, the top weakness line 110 is asymmetric relative to the bottom weakness line .114 which is symmetric relative to a vertical plane crossing the diameter of the stopper 100. So when molding or further slitting. the stopper 100, the top weakness line 110 is angularly switched or turned offset in relation with the position of the hinge(s) 118 Of the bottom weakness line 114. Thus, one strip 108 (c.a.,. the left strip) in a clockwise screwing configuration, is shorter than the opposite strip 108 (e.g., the right strip). In other embodiments, such as Show in. Figure 3, the -bottom weakness line 114 is symmetric relative to a vertical plane crossing the diameter of the stopper 100 where the plane being shown by a fine continuous line.
100381 While various embodiments. of the invention have been described, it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible that are within the scope of this invention.
