Abstract
Description
- This invention relates to a tethered plastic screw stopper.
- 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.
- 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.
- Usually the bottle neck includes outer fixation feature, such as thread(s) for screw type stopper or annular fixation rings for snap type stopper, to secure the stopper on the bottle neck.
- 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 force 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.
- 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.
- The roof may be removable. During bottle opening, the bridges form 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.
- 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.
- 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.”
- U.S. Pat. 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 close 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 unmovable and as capable of toggling around the hinges beside of the stopper secured on the bottle neck.
- U.S. Pat. No. 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.
- 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.
- 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 each strip are directly linked to the closure shell through a junction point.
- The stopper 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 screwing direction of the closure shell.
- Thus, the invention systematically allows the nearest bottom bridge to be 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.

Emphasis is placed on illustrating the principles of the invention. In the figures, like reference numerals designate corresponding parts throughout the different views.

- This invention relates to a tethered
plastic screw stopper 100 for closing abottle neck 102. Thestopper 100 is integrally made of one plastic piece by a molding fabrication step. Other parts or elements of thestopper 100 can be further created into the entire plastic piece through a cutting or slitting step. - The
stopper 100 is a screw type and comprises inner fixation features, such as thread(s), designed to cooperate with outer complementary fixation features made on thebottle neck 102. - In some embodiments, as illustrated in
FIGS. 1 through 4 , the screwing direction of thestopper 100 is typically clockwise and extends from right to left. The screwing orientation is represented as a directional arrow inFIGS. 1 through 4 . The unscrewing direction of thestopper 100 oppositely extends relative to the screw direction, so counterclockwise from left to right. In other embodiments, the screwing direction can be designed counterclockwise. - The
stopper 100 comprises aclosure shell 104 and underneath atamper band 106. Thetamper band 106 and theclosure shell 104 are separably linked together by way of astrip 108. - In some embodiments, the
stopper 100 includes onestrip 108. In other embodiments, thestopper 100 includes two or more strips 108. For example, thestopper 100 includes twostrips 108 positioned on opposite sides of thestopper 100. The twostrips 108 can be positioned in a symmetrical or asymmetrical layout. - The
strip 108 is separably connected to theclosure shell 104 through a plurality oftop bridges 112 that form atop weakness line 110. Similarly, thestrip 108 is separably connected to thetamper band 106 through a plurality ofbottom bridges 116 that form abottom weakness line 114. - The
bottom weakness line 114 comprises at least onehinge 118 configured to connect thestrip 108 and thetamper band 106. In some embodiments, thebottom weakness line 114 comprises twohinges 118 where each hinge 118 connects arespective strip 108 to thetamper band 106. The two hinges 118 can be spaced through a hole or a less thick material managed into thetamper band 106 between the two hinges 118. - The
top bridges 112 andbottom bridges 116 are each configured to be stretched and ultimately broken when unscrewing theclosure shell 104. The top andbottom bridges bottom weakness lines bottom bridges - Each
strip 108 comprises an extremity at an end of thetop weakness line 110, linking thestrip 108 with theclosure shell 104 at ajunction point 120. For example, in the embodiment having twostrips 108, there is ajunction point 120 at each end of thetop weakness line 110, linking the extremity of eachstrip 108 to theclosure shell 104. - The
top weakness line 110 is configured in order to form anend 122 of thestrip 108 positioned above abottom bridge 116 located at the nearest to thehinge 118 on the left side of the hinge considering a clockwise screwing direction of theclosure 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 thehinge 118 is located over the nearest left bottom bridge 116 (denoted with parallel vertical lines inFIG. 2 ). - 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 thebottom bridge 116 located at the nearest from thehinge 118. In some embodiments, thehinge 118 is more particularly located between −20° to 20° relative to the vertical axis of thebottom bridge 116 located at the nearest from thehinge 118. For example, when looking at thehinge 118, thejunction point 120 of theleft strip 108 is angularly situated approximately 20° relative to the leftnearest bottom bridge 116. Such angular variation is shown in the drawings illustrated in dotted lines onFIGS. 3 and 4 . - In some embodiments, the
top weakness line 110 is asymmetric relative to thebottom weakness line 114 which is symmetric relative to a vertical plane crossing the diameter of thestopper 100. So when molding or further slitting thestopper 100, thetop weakness line 110 is angularly switched or turned offset in relation with the position of the hinge(s) 118 of thebottom weakness line 114. Thus, one strip 108 (e.g., 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 inFIG. 3 , thebottom weakness line 114 is symmetric relative to a vertical plane crossing the diameter of thestopper 100 where the plane being shown by a fine continuous line. - 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.
