The invention discloses a locking structure of a cup. The locking structure comprises a cup body and a cup cover. The cup body is provided with a first buckle, and the cup cover is provided with a second buckle adaptive to the first buckle. The locking structure further comprises a lock catch which is movably arranged on the cup cover up and down. The lock catch is provided with a bolt. Correspondingly, the cup body is provided with a bolt hole adaptive to the bolt. The cup cover rotates on the cup body, so that the first buckle and the second buckle are matched. When aligned, the bolt falls into the bolt hole, thereby realizing rotary locking.

A package includes a container with a crown closure bead and an external thread segment having a diameter greater than that of the crown closure bead, a crown closure coupled to the crown closure bead, and a multi-piece closure assembly coupled to the crown closure and the container. The closure assembly includes an inner shell, a seal liner carried by the inner shell and positioned against the crown closure, and an outer shell. The inner shell has an inner skirt having at least one internal thread segment to cooperate with the external thread segment of the container. The outer shell has an outer skirt with an internal retention bead for cooperating with an external retention bead of the inner shell to retain the shells together in an axial direction, and outer child-resistant engagement features to cooperate with inner child-resistant engagement features of the inner shell.

A wine bottle is provided with a punt at a lower end which includes a cork retainer therein. A cork which closes an opening at an upper end of the bottle, can thus be stored within the cork retainer in the punt of the bottle, when not in use closing the opening. In one embodiment, the cork retainer includes two retainer surfaces which are opposing each other horizontally, and spaced apart by a length similar to opposing portions of the cork to allow the cork to fit tightly between these retainer surfaces. Space above the retainer surfaces can hold a foil wrap with the cork within the cork retainer and holding the foil wrap in place. The cork and foil can thus remain with the bottle before, during and after use. Full re-use of the bottle is thus facilitated. In one embodiment, the bottle has an octagonal shape so that multiple bottles can be shipped together and placed adjacent each other with flat surfaces distributing loads therebetween, without forces concentrated at points thereof, and to keep the bottles in good shape for washing, re-filling and re-use.

There is provided a vial cap with which, when there is a possibility that a cover which covers a stopper for a vial has come off and the stopper for the vial has been contaminated at a stage prior to use, the fact can easily be recognized. The vial cap is a resin vial cap (1) to be attached to a mouth portion (72) of a vial (70) to fix a stopper (74) fitted into the mouth portion (72) so that the stopper may not come off the mouth portion (72). The vial cap (1) is provided with a cap main body (8) that has an upper opening (6) formed therein and a cover (40) that covers the upper opening (6) of the cap main body (8). The cap main body (8) has a plurality of pin-receiving holes (10) formed therein, and the cover (40) has a plurality of fixing pins (46). Each pin-receiving hole (10) and a fixing pin (46) that is paired with the pin-receiving hole (10) are formed in complementary shapes. The plurality of fixing pins (46) of the cover (40) are accommodated in the plurality of pin-receiving holes (10) of the cap main body (8), and the cap main body (8) and the cover (40) are joined with the pin-receiving holes (10) and the fixing pins (46) engaged.

A cap unit is provided which provides improved convenience. The cap unit is attached in a detachable manner to a neck portion of a container main body, an upper portion of which is open. The cap unit includes a cap main body that blocks an upper opening of the container main body and in which a liquid flow spout is provided in an upper portion, and a lid that opens and closes the liquid flow spout in a state of being attached to the cap main body in a rotating manner using a hinge portion, in which a maintaining member maintains an open state of the lid at a position at which the lid opens the liquid flow spout is provided in the hinge portion.

A method of manufacturing a textured-smooth hybrid metal closure cap, and a closing caps produced by the method. The method includes a) the supply of a strip or sheet, made of aluminum alloy known as a “textured” strip or sheet, typically coated on at least one of its faces by a stampable lacquer, b) a first operation for cutting discs, called blanks, c) a step for stamping, in one or more passes, of said blank metal, typically using a stamping lubricant, so as to form a stamped blank, comprising a head and a skirt, typically axially symmetric in the axial direction, d) a step for degreasing said stamped blank, typically intended to eliminate the remaining lubricant, to form a degreased blank that can be lacquered, and e) an optional step of protective lacquering and decoration. After the stamping step, and before the lacquering step, at least one drawing step consisting in passing the stamped blank through drawing rings in order to stretch and thin the metal.
