(9) Various embodiments of the present disclosure are disclosed herein. The described embodiments are merely exemplary illustrations of implementations set for a clear understanding of the principles of the disclosure. 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.

(10) FIG. 1 illustrates a screw stopper 102 in an open position relative to a bottle neck finish 100. The bottle neck finish 100 includes outer threads 110, an evident tamper ring 112, and a transport ring 114. The stopper 102 includes a closure shell 104 connected to a tamper band 106 using a strip 108.

(11) In some embodiments, the bottle neck finish 100 includes engaging features (e.g., threads 110) meant to engage with complementary engaging features (not illustrated) located on the inner surface of the closure shell 104. In other embodiments, the bottle neck finish does not include engaging features (e.g., threads), and the closure shell 104 is secured onto the bottle neck finish 100 through other securing means, such as snaps, clasps, or other mechanically engaging features.

(12) Before opening (e.g., during sealing), the stopper 102 is positioned (e.g., forced in a downward motion) onto the bottle neck finish 100 in such a way that the tamper band 106 is secured under the tamper evident ring 112 of the bottle neck finish 100. For example, the closure shell 104 is secured onto the bottle neck finish 110 by the outer threads 110 engaging with inner threads of the closure shell 104 as the tamper band 106 is positioned below the tamper evident ring 112. In some embodiments, the tamper band 106 comprises retaining features, such as an inner collar (not illustrated) to prevent the tamper band 106 from moving above the tamper evident ring.

(13) During opening, a user to alters the position of the stopper 102, for example by twisting the closure shell 104 (where threads exist) or removing the closure shell 104 from a mechanically securing feature. As the bottle is opened, the strip 108 keeps the closure shell 104 connected to the tamper band 106. Specifically, the stopper 102 is not completely removed from the bottle because the strip 108 is attached at one end 118 to the closure shell 104 and at opposite end 120 to the tamper band 106, as illustrated in FIG. 1. In some embodiments, the strip 108 configured such that the closure shell 104 is positioned under the transport ring 114 thus avoiding the closure shell 104 from interfering with the user (e.g., drinking or pouring).

(14) Because the closures shell 104 remains connected to the tamper band 106, the closure shell 104 can be positioned (e.g., by the user) to different locations around the bottle neck finish 100. For example, the tamper band 106 can rotate around the bottle neck finish 100, still secured under the tamper evident ring 112.

(15) In the invention, the strip 108 is configured to be secured into a retaining feature 116 of the transport ring 114, thus allowing the closure shell 104 to remain attached to the tamper band 106 while the bottle is open. The transport ring 114 is necessary for blowing process to create a plastic bottle from a preform. The transport ring 114 extends outwardly around the shape of the bottle neck finish. In order to maintain the integrity of the transport ring 114 (e.g., for sealing during blow molding), the retaining feature 116 is incorporated at a peripheral edge transport ring 114.

(16) The retaining feature 116 can be integrated into, formed within, and/or otherwise affixed to the transport ring 114. For example, the retaining feature 116 can be integrated into the transport ring 114 during an injection molding process. As another example, the retaining feature 116 can also be subsequently created within the transport ring 114, during a cutting or machining process after molding of the transport ring 114. As yet another example, the retaining feature 116 can be subsequently affixed to the transport ring 114 during a post manufacturing process.

(17) In some embodiments, a portion of the strip 108 close to the end 118 attached to the closure shell 104 is configured to inserted into the retaining feature 116. In other embodiments, a portion of the strip 108 close to the end 120 attached to the tamper band 106 is configured to be inserted into the retaining feature 116.

(18) In some embodiments, more than one retaining feature 116 is present within or subsequently attached to the transport ring 114. The retaining features 116 may be distributed, evenly or otherwise, about the perimeter of the transport ring 114.

(19) As illustrated in FIG. 2, the retaining feature 116 comprises a hollow area 200 formed into the peripheral edge of the transport ring 114. Because the tamper band 106 allows the stopper 102 to turn around the bottle neck finish 100, the user can position the strip 108 into any available retaining feature 116. Specifically, the retaining feature 116 is configured (e.g., shaped) to receive the strip 108 after the opening of the bottle. In some embodiments, the strip 108 is locked into the retaining feature 116. For example, the user pushes the strip 108 inside the hollow area 200, in order to prevent the closure shell 104 to spring back close to the bottle neck finish 100.

(20) Depending on whether the retaining feature 116 is intended to receive and lock the strip 108, the hollow area 200 is dimensioned relative to the thickness of the strip 108, so that at least a portion of the strip 108 that is inserted into the hollow area 200 can be retained by the hollow area 200 without additional effort of the user (i.e., the strip locks into the hollow area 200).

(21) In some embodiments, the retaining features 116 are shaped the same. The shape can be any shape that allows the retaining feature 116 to receive and/or lock the strip 108. For example, the retaining feature 116 can be semicircular (as illustrated in FIG. 2). In the embodiment shown in FIG. 2, some of the hollow areas 200 have a semicircular shape, relative to the outer peripheral edge of the transport ring 114. In other embodiments, as illustrated in FIG. 3, hollow areas 300 are squared or polygonal in shape. Other geometric shapes or shape combinations can be used to form the hollow areas 200, 300 according to the characteristics (e.g., shape and thickness) of the strip 108, in order to improve the locking of the strip 108 into the hollow area 200 or 300.

(22) In other embodiments, the retaining features 116 are shaped differently from one another. For example, some of the retaining features 116 illustrated in FIG. 2 are semicircular and other retaining features 116 contain both semicircular and linear components (e.g., hollow area 202). The retaining features 116 can be shaped differently, for example, to accommodate receiving the strip 108 at a position that is not perpendicular to the transport ring 114. Additionally, or alternatively, manufacturing processes may create retaining feature(s) 116 having different shapes. For example, a cutting process may create retaining features 116 that are shaped differently depending on factors such as the position of the blade.

(23) In some embodiments, the stopper 102 includes more than one strip 108. Where the stopper 102 includes multiple strips 108, it is possible to lock each strip 108 into a different retaining feature 116.

(24) 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.
