A closure (101) for a container neck comprises a first portion (102) comprising a body (104) for fixing to the container neck and a second portion (103) comprising a cap (105) releasably engageable with the body (104). The closure (101) comprises a seal support portion (107) formed from a first plastics material and a seal (106) formed from a second plastics material that is more compliant than the first plastics material, the seal (106) formed integrally with the seal support portion (107). A closure (101) with a bi-injection moulded seal. A method of forming the closure (101) comprising the step of bi-injection moulding the seal support portion (107) and the seal (106). A container comprising a container neck provided with the closure (101).

A thread joining mechanism which possesses and for annular engaging external surface and/or internal surface, preferably for the containers with annular opening, comprising: at least an external thread line, including upper end and lower end which outspread along annular engaging external surface and/or internal surface, at least a convex fixed area and locking piece, preferably be processed as configuration by a part of said upper end and lower end which close to said external thread line, or preference is given to the convex part that integrates with said annular engaging external surface and/or internal surface, said fixed area and locking piece are set to that said annular engaging external surface and/or internal surface, and upper end and/or lower end of corresponding said thread line are separated by preset spacing, and outspread along the same direction with said thread line.

Containers with closures are disclosed. A closure may include at least a polymer orifice reducer configured to be permanently secured to a rim of an opening of a container and a flexible tamper evident seal disposed on the topside of the orifice reducer. The flexible tamper evident seal, optionally foil, covers one or more openings in the orifice reducer. Processes for permanently securing a closure to a container, optionally by forming a heat seal between the orifice reducer and container rim, are also disclosed.

A pressure relief cap includes a body engageable with a container and rotatable about an axis for coupling or decoupling the body from the container. The pressure relief cap also includes a handle and a motion control mechanism operable to selectively couple the handle to the body. The motion control mechanism includes a clutch plate moveable between an engaged position in which the clutch plate permits torque transfer from the handle to the body, and a disengaged position in which the clutch plate inhibits torque transfer from the handle to the body. The pressure relief cap also includes a relief valve for releasing pressure in response to elevated pressure within the container.

A system for opening a secure specimen sample bottle includes a base having a first area and a first raised hollow portion for receiving and holding the specimen sample bottle. The first raised hollow portion has a groove formed along an outer surface thereof. The system includes a cutter for cutting a first portion of the specimen sample bottle. The cutter has a handle at a first end and a second end portion that receives the first portion of the specimen sample bottle and a blade for cutting the first portion. The second end portion has a flange with a raised rail formed along an inner surface of the flange, with the raised rail being received within the groove to couple the cutter to first raised portion during performance of a cutting operation.

The present invention relates to a container assembly including a container body for accommodating contents and a cap device detachably installed on the container body, and the cap device includes a first coupling part detachably coupled to the container body and a pass-through device through which the contents accommodated in the container body pass. The cap device includes a holder on which the first coupling part is formed and a cap body including the pass-through device, the holder includes a cylindrical inner wall and a bottom part extending from a bottom of the cylindrical inner wall along an outer circumference thereof, and the first coupling part is formed on an inner circumferential surface of the cylindrical inner wall and screw-coupled to the neck part.

A secure specimen sample bottle includes a base container for receiving a specimen. The base container has a plurality of locking protrusions formed along an inner surface of the base receptacle. A bottle includes a lock ring that has an upright spire structure that has a closed top end and the opposing open bottom end including a plurality of flexible fins that are configured to interlockingly mate with the locking protrusions so as to prevent removal of the lock ring relative to the base container upon engagement of the flexible fins to the locking protrusions. A removable cap is coupled to the lock ring.
