A reciprocating engaging mechanism is applied to an airtight device and includes a shaft, a rotary plate, a plurality of first engaging components and a linkage module. The rotary plate is rotatably disposed on the shaft. A plurality of bridging bars of the linkage module is connected between the rotary plate and the plurality of first engaging components in a respective manner, rotation of the rotary plate drives the plurality of bridging bars to rotate in the same direction, so as to switch the plurality of first engaging components between a locking mode and an unlocking mode.

The fly swatter storage device includes a pan structure, a door structure, a latch structure, and a fly swatter. The fly swatter forms the tool of the fly swatter storage device. The door structure attaches to the pan structure to form a protected space. The protected space contains the fly swatter when the fly swatter is not in use. The door structure attaches to the pan structure such that the door structure rotates relative to the pan structure between a closed position and an open position. The latch structure secures the door structure in the closed position. The fly swatter exchanges momentum with the insect such that the insect is placed in a state of reduced consciousness.

A stacking assembly and a stacking system are provided. The stacking assembly has an accommodating space. The stacking assembly includes a first connecting member and a second connecting member. The first connecting member is configured to form at least one of an upper surface of the stacking assembly and a lower surface of the stacking assembly. The second connecting member is connected to the first connecting member to form the accommodating space. A material of the first connecting member is different from a material of the second connecting member.

A storage container may include a frame structure having a hinge with a pivot axis, a first frame component, and a second frame component coupled to the first frame component by a hinge; a first shell and a second shell; and one or more securing structures configured to facilitate isolation of an interior volume from the space exterior to the interior volume and maintenance of the storage container in a closed configuration. When the storage container is in a closed configuration, an interior volume bounded by the frame structure, first shell and second shell may be isolated from a space exterior to the interior volume.

Self-closing drum lids that automatically close at controlled rates are disclosed. When the lid is manually rotated to a fully open position, it automatically begins self closing with a transition from a relatively slow rate that allows a user to add material and/or remove material from the drum without having to hold the lid open by hand. After the slow-closing stage, the lid begins to close at a faster rate until the lid rotates to a fully closed position on the drum. The self-closing drum lids may be attached to a drum via a drum band, and may include a latching mechanism.

A lid stay for a transport container. The lid stay has at least one bearing unit, at least one guide unit and at least one swivel bracket. The lid stay can be moved at least between a locking position and a transport position. Furthermore, the guide unit has at least one latching element. In the locking position, the swivel bracket interacts with the latching element in such a way that the lid stay is held in the locking position. The latching element causes at least a temporary elastic deformation of the swivel bracket when the lid stay is moved between the locking position and the transport position.

A lock box for wire cable clamps includes a body, a hinge, a first end face, a second end face, and a locking assembly. The body is hollow and divided into a first body section and a second body section. The hinge pivotably connects the first body section and the second body section to permit opening of the body and closing of the body about wire cable clamps on a wire cable. The first end face and the second end face are positioned at opposite ends of the body, each having an aperture designed to permit passage of a wire cable therethrough and prevent passage of wire cable clamps therethrough when the body is closed about the wire cable clamps on the wire cable. The locking assembly is positioned on the body and is engageable by a lock to releasably lock the first body section and the second body section.

A container for objects comprises an outer casing with walls defining an internal volume and padding inserted into the internal volume of the casing. The outer casing is made of thermoformed plastic material, and the padding consists of a shaped foam shell, of a shape and size adapted to the shape and size of the internal volume of the casing. A method of manufacturing the object container comprises: providing at least one sheet of a thermoformable plastic material; thermoforming the at least one sheet of thermoformable plastic material to form an outer casing of the container; forming a padding consisting of a shaped foam shell, of a shape and size adapted to the shape and size of an internal volume of the outer casing of the container; inserting the padding into the internal space of the outer casing of the container.

A cosmetic container includes an internal cover, an internal tray and a hinge. The internal cover is made of metal and includes a frame, two holding elements extending from the frame, and a gap between the holding elements. The internal tray is made of metal and includes a frame, two holding elements extending from the frame of the internal tray, and a gap between the holding elements of the internal tray. The hinge includes two leaves. The first leaf is sandwiched between a face of the internal cover and a face of each of the holding elements of the internal cover. The second leaf is pivotally connected to the first leaf and sandwiched between a face of the internal tray and a face of each of the holding elements of the internal tray.
