A receptacle forming a chamber partially filled with an active substance, wherein the receptacle is a body and a cap which closes the body. The cap includes a top wall with a first main side facing an interior of the chamber and a skirt formed with the first main side of the top wall. The body includes a bottom wall and a sidewall. The skirt and the sidewall surround one another in contact with each other. The walls surrounding the chamber include the bottom wall, the top wall and either the skirt or the sidewall. At least one ventilation path is provided between the skirt and the sidewall, such that the ventilation path connects the chamber with the outside atmosphere.

A venting device comprises an air channel and a rotary venting rod, wherein: the air channel comprises a first end facing an outer surface of the rotary venting rod and a second end away from the rotary venting rod; the outer surface of the rotary venting rod is provided with a recessed venting slot in fluid communication with ambient air, about which the rotary venting rod may be rotated about a rotation axis extending longitudinally thereof to provide a vented state and a sealed state. In the vented state, at least a portion of the venting slot of the rotary venting rod is in fluid communication with the air channel and thereby brings the air channel into fluid communication with ambient air via the venting slot. In the sealed state, the venting slot of the rotary venting rod is not in fluid communication with the air channel and the first end of the air channel is sealed by the outer surface of the rotating vent rod. The venting device of the present invention is easy to manufacture and assemble. The present invention also relates to a lid comprising the above-mentioned venting device and a container comprising the lid.

The present disclosure relates to a blockage and a smart cleaning device. The blockage includes a plug body and a hierarchical sealing structure. The plug body is a shaft-shaped structure as a whole, and is provided with a through hole that penetrates the plug body. The hierarchical sealing structure is sleeved on an outer side of the plug body, and is provided with at least two annular plugs stacked in an axial direction of the plug body.

A sterile container includes a container pan, a container cover, a closure for closing the sterile container, and a seal or sealing element between the container pan and the container cover. The seal or sealing element is vapor-permeable.

A sterile container includes a container pan, a container cover, a closure for closing the sterile container, and a seal or sealing element between the container pan and the container cover. The seal or sealing element is vapor-permeable.

A closure for a beverage container has a body having an attachment interface to engage to a top of a beverage container, a sealed, elongated enclosure attached to an underside of the body, and a single access element adapted to selectively open and close either a first opening passing through the body into the sealed, elongated enclosure or a second opening passing through the body directly to an inner volume of the beverage container.

A lidding device (102) includes a first panel (104) comprising a lid (106) configured to cover and seal a food container (108). A second panel (110) is foldably connected to the first panel. A third panel (112) includes a bottom panel opposite the lid, wherein the second panel is foldably connected to the first panel and the third panel. A fourth panel (114) is foldably connected to at least one of the first panel and the third panel, wherein the fourth panel and second panel are configured to at least partially enclose a food container between the second and fourth panels.

A food serving device for protecting food from insects includes a plate, which has a primary edge and a set of secondary edges. The primary edge is linear. A rim is engaged to and extends from a perimeter of the plate so that the plate and the rim define a tray. A food item is positionable in the tray. A lid is hingedly engaged to the rim above the primary edge. The lid is positioned to selectively close a top of the tray to protect the food item from an insect. The lid is transparent and thus allows viewing of the food item. A plurality of holes is positioned in the lid to vent an interior space defined by the tray and the lid. Each hole has a diameter of less than 1.40 mm so that the holes deter entry of the insect into the interior space.

A sealing structure for a multi-compartment box body, comprising: a box body, a box cover and an elastic sealing strip. Inside the box body is arranged at least one partition plate which divides the box body into two or more compartmentalized areas. The sealing strip includes an integral elastic sealing strip and a compartment elastic sealing strip, and both strips are integrally formed. The bottom end of the cover is provided with a protruding portion extending to the inside of the body, the peripheral side of the protruding portion is provided with an integral elastic sealing strip routing groove adapted to the integral elastic sealing strip, and the bottom end of the protruding portion is provided with a compartment elastic sealing strip routing groove adapted to the compartment elastic sealing strip. The both groove are communicated to each other.

A disposable syringe for use with a pneumatic driver. The syringe has an elongated barrel with a cap secured to the proximal end that has a through bore. A filter is secured to the cap interior of the barrel that covers an opening in the through bore interior of the barrel. The pneumatic driver includes a source of pressurized air; a support for receiving and locating the syringe; and a supply block configured to receive pressurized air from the source and having an outlet for delivery of pressurized air. The supply block is movable between a first position spaced apart from the cap of the syringe and a second position in contact with the cap with fluid communication being established between the outlet of the supply block and the through-bore in the cap.
