A liquid storage container includes: a discharge port member including a discharge port through which liquid stored in a storage portion is discharged; a cover portion configured to be attachable to the discharge port member and to be capable of opening and closing the discharge port; and a sealing portion formed of a contact portion between the cover portion and the discharge port member. The cover portion includes a groove structure between an outer periphery of the cover portion and the sealing portion.

A liquid storage container includes: a discharge port member including a discharge port through which liquid stored in a storage portion is discharged and a coupling portion in which a male thread portion is arranged on the outside; and a cover portion including a female thread portion on the inside and configured to be attachable to the discharge port member, the female thread portion configured to be screwed to the male thread portion, in which the male thread portion is discontinuous in the coupling portion.

A drink and mist bottle cap is detachably attachable to a bottle to enable a person to produce a mist from a pump and mist nozzle and also drink from a drink spout. A drinking spout has a drink spout cap that is detachably attachable over the drinking spout to seal the liquid contents within the bottle when not drinking form the bottle. The drink and mist bottle cap may also have an anti-backwash valve that is configured to prevent backwash from flowing back into the interior of the bottle and an ultraviolet light configured to produce a disinfecting ultraviolet light within the bottle, and a pressure relief valve to allow pressure equalization when there is a pressure differential between the interior of the bottle and the exterior of the bottle.

A breakseal providing desired compliance characteristics for a reliable seal between the fitment of a liquid dispenser and the breakseal. A compliant material is provided on the non-wetted face of the breakseal, enabling compliance of the breakseal on a wetted face for sealing between the breakseal and the mating component. The breakseal may also include raised features on segments that are separated after rupturing that prevent or mitigate scoring of O-ring seals upon probe insertion. A wiping feature that provides redundant sealing between the breakseal and a mating cap or other mating connection may also be incorporated into the breakseal. The breakseal can also include a flat on an outer perimeter that may serve as a gate for injection molding, so that any gate vestige from the molding process will not protrude beyond the outer diameter of the breakseal to cause unwanted interference between the breakseal and the mating connection.

A screw-top closure cap having a collapsible spout nesting within a cap and with a portion of the spout seated coaxially within the container neck itself is disclosed. Both the spout and the cap incorporate child-resistant features to prevent unwanted removal of the closure and/or use of the spout.

A closure assembly (20) that includes a cap or overcap (28) and a fitment (24) for a container is provided wherein the fitment (24) has a laterally projecting shear member (40), and the overcap (28) has an aperture (74) for initially receiving the shear member (40) when the overcap (28) and fitment (24) are in an initially assembled orientation or condition. The aperture (74) and the shear member (40) cooperate in the initially assembled orientation such that when subjected to a flow of a sterilizing gas, turbulence is created in the sterilizing gas flow to enhance sterilization of the combination. The closure assembly (20) may, instead, or additionally, be provided wherein the overcap (28) has an elongate, hollow plug (58) for establishing a first seal between the fitment (24) and the overcap (28) in the initially assembled orientation, and the wherein overcap (28) has a skirt (50) for establishing a second seal between the fitment (24) and the overcap (28) in the initially assembled orientation.

A spout assembly for a flexible bag having a base flange, a body and a dual lead thread. The base flange has a top surface and a bottom surface. At least one of the top surface and the bottom surface are configured for coupling to a flexible bag. The body extends from the base flange and includes a proximal end corresponding to the base flange and a distal end spaced apart therefrom, and, an inner surface and an outer surface. The dual lead thread extends along the outer surface of the body between the proximal end and the distal end. The dual lead thread has a first threadform and a second threadform. The first threadform has a first threadform length. The second threadform has a second threadform length. The length of the first threadform is different than that of the second threadform.

Disclosed is a connection device to be coupled with a container neck in different standards for use. The connection device is formed with a mouth part at the upper side and a screw thread part at the lower side. The mouth part at the upper portion of the connection device is formed in a screw thread or other shape in the standard corresponding to a bottle lid, and the inside of the screw thread part is formed with a screw thread corresponding to the standard of the container neck. The screw thread is integrally formed or an elastic screw thread is additionally added for the coupling with the necks of a plurality of containers.

A tamper-resistant, refillable paint container featuring a double tamper-evident A locking system. The container includes an inverted frustum conical liquid receptacle with external threading and male locks. A tamper-resistant lid with internal threading, a first tamper-evident locking ring with internal female ratchet locks, and break-off fingers engages the receptacle. A hollow neck extends from the lid, with external threading and male locks. A cap with internal threading, a second tamper-evident locking ring with internal female locks, and break-off fingers engages the hollow neck. The cap is installed onto the lid prior to filling, and the lid with the locked cap is secured onto the receptacle after filling. Removal of the cap or lid causes the break-off fingers to detach, providing tamper evidence. The container enhances user convenience, reduces spills, and provides cost savings through efficient nesting during shipping and storage.
