The present disclosure provides a folded side plate locking mechanism and a folded pull rod storage box, wherein the folded side plate locking mechanism includes a lock body, a lock tongue and an elastic body. When a folded side plate is unfolded in a plane, a retaining ring is provided on a lock catch, and the lock body is pressed to keep the lock catch far away from a side wall of the retaining ring. The lock body and the lock tongue are in an unlocked state. At the same time, the elastic body is deformed under force to accumulate energy. An included angle is formed in the folding process of the folded side plate. The lock tongue is separated from the lock catch. The lock body is released. The lock body is restored to a locked state under the elastic force of the elastic body.

The package includes a base, a primary lid connected to the base, the primary lid and the base defining a primary storage area, and a locking mechanism. The locking mechanism includes a flexible member including a first segment and a second segment that are connected by an elbow, the first segment being connected to the primary lid, a distal end of the second segment including at least one contact structure, the flexible member including at least one first engaging structure between the elbow and a front surface of the at least one contact structure, and a second engaging structure on a first wall of the base. The container includes a receptacle wall cooperating with a peripheral wall to define a receptacle, and a flexible tab projecting from the top wall, the flexible tab including a fixed end adjacent to the top wall and a free end opposite the fixed end.

Provided is a substrate storage container that can eliminate lower coupling strength between a slide member and bent locking member, and bent locking member falling from the slide member without a metal pin. The container includes a lid fitted to an open front face of a container body, and locking mechanism that locks the lid. The locking mechanism includes an operating reel supported on the lid and turned by external operation, connecting bar that slides to vertical direction of the lid as the reel turns, locking claw projected from a passage opening in the periphery of the lid as the connecting bar slides and can be engaged with a locking pocket on front inner circumference of the container body. The locking claw is coupled rotatably at distal part of the connecting bar by a resin pin which can reduce generation of metal ions and eliminate adverse effects on semiconductor wafers.

The package includes a base, a primary lid connected to an upper portion of the base via a first hinge, the primary lid and the base collectively defining a primary storage area when the primary lid is in a closed position, and a locking mechanism on a first end of the package, the locking mechanism including a flexible member including a first segment and a second segment that are connected by an elbow, the first segment being connected to the primary lid, a distal end of the second segment including at least one contact structure, the flexible member including at least one first engaging structure between the elbow and a front surface of the at least one contact structure, a second engaging structure on a first wall of the base, the flexible member being in a first position when the primary lid is in the closed position.

The present application provides a cap assembly and a bottle assembly. The cap assembly is configured to lock a bottle. The bottle includes a bottle head having at least one lock accommodating portion and comprises a bottle body. The cap assembly includes a cap, an elastic arm and at least one lock portion. The cap defines an annular receiving portion having an opening facing downward, and the bottle head can enter the receiving portion through the opening. The elastic arm is annular and is arranged in the receiving portion. The at least one lock portion is arranged on the cap and is configured to be capable of cooperating with the at least one lock accommodating portion of the bottle head, so as to lock the cap assembly to the bottle head. When the cap assembly is locked to the bottle head, the elastic arm abuts against a top wall of the receiving portion and a top wall of the bottle head, to apply forces in opposite directions to the cap and the bottle head, so as to retain the at least one lock portion in the at least one lock accommodating portion. The cap assembly of the present application has a relatively small height, and during unlocking of the bottle assembly of the present application, gas in a bottle body cavity can be discharged from the bottle through an exhaust passage.

A rack includes: a casing; M pairs of supports that are provided inside the casing so as to extend in a depth direction and arrayed at regular intervals in an up-down direction; and a lock mechanism that locks returnable containers each housed while being supported so as to be slidable along one pair of supports. The casing of the rack is divided into N rows by (N1) partition plates, with the M pairs of supports provided in each row, to be able to house a maximum of (MN) returnable containers. The lock mechanism is provided in each of the (N1) partition plates so as to extend through the partition plate and correspond to each tier, and simultaneously locks two returnable containers that are housed adjacent to each other on one side and the other side of the partition plate.

A rotationally locking container includes a body and a lid, with a sealing structure provided between the body and the lid. A rotational locking structure is provided between said body and said lid. The rotational locking structure includes a downwardly recessed rotating groove provided on the lid, a knob disposed within the rotating groove, and at least two outwardly extending locking tabs provided on the knob. The mouth of the body is provided with a protruding edge extending upwardly beyond the lid, and said protruding edge is provided with at least two locking holes, wherein the locking tabs are configured to cooperate with the locking holes. Compared to existing containers on the market, the adoption of the rotational locking structure, wherein the cooperation between the locking tabs and the locking holes is less prone to wear, offers the advantages of simpler operation, more reliable locking, and a longer service life.

A container body, provided with a storage cavity and an opening in communication with the storage cavity; and a container cover, covering the opening of the container body, the container cover including an upper cover, a press locking portion, a lateral unlocking portion, and a sealing cover, the upper cover being provided with a mounting recess, the press locking portion being movably arranged in the mounting recess, the lateral unlocking portion being arranged on a side portion of the press locking portion, and the sealing cover being located in the storage cavity and linked to the press locking portion; when the press locking portion is pressed downwards to a locking position, the sealing cover closes the opening; and when subjected to a lateral pressing force, the lateral unlocking portion unlocks the press locking portion, and the sealing cover opens the opening.
