Disclosed is a test barrel, to prevent a test liquid in the barrel from sputtering into a connection gap due to shaking of the barrel to hence cause contamination, improve the measurement accuracy in case of multiple tests, and meanwhile improve the operability of screwing on and screwing off the entire device during use of the device. The above technical objective of this utility model is implemented by employing the following technical solution: a test barrel, comprising barrel lid and a barrel body; wherein the threaded rings are arranged on an inner wall of a side face of the barrel lid and an outer wall of an opening of the barrel body, a rotary force applying portion is arranged on an outer wall of the side face of the barrel lid, and during engagement, a liquid blocking washer is arranged between the barrel lid and the barrel body, wherein a radial width of the liquid blocking washer is greater than a thickness of the opening of the barrel body.

A lid assembly for a food container is described that may be used to store and transport food items. The container defines an interior to store a food product. The lid assembly includes a lid and a stopper that is sized to close an opening of the container. A biasing member urges the lid to an open position when the lid is unlocked or unlatched.

The present invention relates in general to the improved containment of biological fluids. In particular, a method and apparatus for collection and preservation of fluid samples in accordance with the present invention results in collection of semen having improved viability both at the time of collection and after storage. The disclosed methods and apparatuses methods support a wide variety of applications for containment of biological fluids related to human and veterinary medicine including, but not limited to, human reproductive medicine and animal husbandry.

An access and/or withdrawal system. The withdrawal system may be used with a container system having an access portal is disclosed. The withdrawal system may be selectively adjustable. The withdrawal system may include a filter member.

Expandable container, made up of a cylindrical container (1), of the type of a soda can, closed at the bottom and open at the top comprising on its outer upper part a thread (2) that will serve to seal the container hermetically by means of a cap (4) and towards the inside a small flange (3) along its entire perimeter, where the screw cap (4) has an internal thread (5) inside, to screw with the external thread of the container (2), and an elastic seal (6) on the upper part of the inner part that will confer tightness to the assembly when the cap is properly tightened; the extensible part is made up of a mobile inner cylinder (7), with a diameter slightly smaller than that of the container, which has a straight perimeter outer flange (8) on its upper edge, which will rest on the top of the container (1), and another flange (9) on its lower edge curved towards the outside that supports the interior wall of the container (1) and that said curved flange (9) carries an elastic joint (10) inside; and when the mobile inner cylinder (7) slides upwards, it does so until the elastic joint (10) located inside the lower flange (9) abuts the lower part of the circular flange (3), the assembly being watertight in that area; and when the mobile inner cylinder (7) is unfolded, the volume of the assembly is increased, so that to the liquid (11) contained in the container another complementary liquid and even some ice can be added, increasing the volumetric level from level (13) to level (14).

An insulated container having a canister can be sealed by a lid structure. The lid structure can be a multi-part insulated lid. The lid can include a vent configured to vent air from inside the canister. In addition, the container may be part of a container kit or container system where one or more inner containers, are nested and secured within the insulated container.

A formulation dispensing device can include a cartridge receptacle to accommodate and/or secure a beverage ingredient cartridge and permit contents within the cartridge to flow into a bottle or beverage container. Additionally, a formulation dispensing device can include a drink through valve that can permit mixed contents from a beverage container to flow through the drink through valve and be consumed. For example, the formulation dispensing device can include ingredients that can be added to a range of different drinks, including sports drinks, dietary drinks, and as a critical life supporting drinks in humanitarian situations. The formulation dispensing device can also include a lid configured to pivot between open and closed positions and can seal the dispensing device which allows the beverage container to be inverted during consumption without leakage through the first aperture.

A sprout lid for use with a container to sprout seeds and or beans is provided which may include a recess feature which may allow the container to be filled with water without removing the sprout lid from the container, as well as allowing proper airflow in the container. The sprout lid may also be used to rinse, strain, and drain seeds and or beans in the container.

A wet sheet storage container. A plurality of male thread parts for screwing a lid body in the circumferential direction are formed on the outer circumferential surface of an upper end part of a container body, and a plurality of female thread parts for threadedly engaging with the male thread parts are formed on the inner circumferential surface of the lid body. The male thread parts are each provided with a base end part formed on the upstream side in the rotation direction of the lid body during installation of the lid body, and a tip end part formed on the downstream side in the rotation direction of the lid body, and the male thread parts are formed such that the height of the tip end part is greater than the height of the base end part.

The invention relates to a cap for closing containers comprising at least one mesh, one foamed polymer and at least one further polymer, and to containers equipped with the cap of the invention.
