A reusable bottle cap system includes a bottle cap and a bottle cap cover. The bottle cap includes a proximal handling portion and a stem that extends from the proximal handling portion to a distal end. The stem has opposing outside and inside surfaces. The outside surface includes a sealing feature for sealing to the mouth of a beverage bottle. The inside surface defines an opening extending to the distal end of the stem. The shell has an inside surface defining a cavity that is closed at a distal end. A pin extends from the distal end of the inside surface of the shell. The pin is received into the opening of the stem to provide a holding force to secure the bottle cap cover to the bottle cap.

An article 10 for insertion into an opening, for example for use as a closure plug in a screw-threaded hole, comprises a body 18 and two projections 22 extending outwardly from the body 18. The outer extent of the projections 22 is circular about the axis of the body 18 except for two gaps 24 which are oppositely disposed. The body 18 is tapered backwards to enable the projections 22 to fold backwards in a compact fashion so that the article can fit large and small diameter openings.
摘要:
A tamper-evident thermoplastic fitment having a spout and a closure for said spout are welded to a polymer-coated paperboard container or to a flexible plastic container. The fitment and closure are initially molded simultaneously but with a substantial space between the two parts interconnected by an elongated runner which conducts molten plastic from the closure to the fitment. Upon retraction of the core of the mold, the closure is pulled into the spout until shoulders on the parts engage, whereupon the closure is stripped from the mold core. The runner comprises a tear tab which slides through an apertured space on the closure. When the parts engage tangs on the tear tab engage the space, making the assembly tamper-evident. The fitment has a flange which may be welded or otherwise secured to the container. The tab may be pulled by the consumer to open the container. The closure may be unscrewed from the spout or otherwise disengaged.
摘要:
A fitment for a container, such as a carton, has an attachment flange adapted to be sealed to the carton around a pour hole therein. The fitment has a cylindrical spout formed with vertically spaced seal bead and locking bead. The closure has a top disk with a depending skirt dimensioned to slidably fit within the spout. The exterior of the skirt has an external locking bead at its lower end positioned to lock under the fitment locking bead to hold the closure in place and a seal surface to be engaged by the fitment seal bead. Initially the fitment and spout are molded as a unit, the locking bead of the closure and the top edge of the fitment spout being joined by a circular frangible link. The combination is tamper-evident since access to the interior of the carton cannot be obtained without breaking the link. As an alternative, the cap may be separated from the spout and slid inside the spout. Separate cooperable means on the cap disk and fitment flange make this alternative tamper-evident.
