A manway cover assembly can be used to control access to the interior of a railroad tank car or other type of tank or structure. The manway cover assembly can have a tightening system, such as a screw tightening system and an attachment system. The attachment system can have a ledge configured to engage a flange that surrounds an opening. A cover can control access to the opening. The tightening system can secure the ledge to the flange and lock the cover over the opening. A manway cover assembly can also be used for selectively sealing an access passageway of a tank. The manway cover assembly can have an internal seal that remains sealed independent of movement between the cover and the opening within a set range of movement.

Disclosed is a liquid pump (100, 200, 300, 400, 500, 600, 700, 800, 900), including a movable unit and a fixed unit. The movable unit is capable of moving relative to the fixed unit so as to pump a product out. An elastic mechanism (130, 230, 330, 430, 530, 630, 730, 820, 930) is provided between the movable unit and the fixed unit, and the elastic mechanism (130, 230, 330, 430, 530, 630, 730, 820, 930) comprises at least one elastic strip (131, 231, 331, 431, 531, 631, 731, 821, 931). The elastic strip (131, 231, 331, 431, 531, 631, 731, 821, 931) applies a biasing force to the movable unit to restore the movable unit after the product is pumped. The liquid pump (100, 200, 300, 400, 500, 600, 700, 800, 900) further comprises an elastic mechanism adjusting member movable between a first position in which the elastic strip (131, 231, 331, 431, 531, 631, 731, 821, 931) of the elastic mechanism (130, 230, 330, 430, 530, 630, 730, 820, 930) is in a relaxed state, and a second position in which the elastic strip (131, 231, 331, 431, 531, 631, 731, 821, 931) of the elastic mechanism (130, 230, 330, 430, 530, 630, 730, 820, 930) is in a preloaded state. With the provision of the elastic mechanism adjusting member, it is convenient to press down a pressing head (110, 210, 310, 410, 510, 610, 710, 910) during use, and the yielding deformation of the elastic strip (131, 231, 331, 431, 531, 631, 731, 821, 931) due to long-term stress can also be avoided.

Disclosed is a dispensing bottle for storing and dispensing a fluid medium. The dispensing bottle comprises a container comprising a cavity for storing the fluid medium. The dispensing bottle further comprises a cap engaged with the container. The cap comprises a first portion and a second portion comprising a top surface disposed above the first portion. The dispensing bottle further comprises a pump engaged with the first portion of the cap and substantially disposed within the cavity. The dispensing bottle further comprises a spout engaged with the pump and extending outside of the cap. The spout being moveable between an open position where the spout extends away from the cap so the fluid medium may be dispensed and a closed position where the spout is disposed slightly above or in contact with the top surface of the second portion of the cap to prevent downward movement of the spout.

A lid apparatus for a multi-chambered container. The lid apparatus has a top-lid that is hingedly attached to a bottom-cap. The top-lid includes one or more openings for fluid filling multiple passages that extend from the bottom-cap. A lower bottom-cap includes welding features for welding to the multi-chambered container. The bottom-cap further includes one or more auxiliary ports for injecting a reagent when the lid apparatus is in a closed configuration sealingly attached to the multi-chambered sample container.

A closure can include a base having an opening. The base can be connected to a container such that a liquid in the container, for example a creamer, is pourable through the opening of the closure into a beverage cup. The closure can include an overcap having a plug, and the plug can seal the opening when the overcap is in a closed position relative to the base. A hinge can connect the overcap to the base and be biased to establish and maintain an angle of the overcap when the overcap moves out of the closed position. Liquid retained on the overcap during opening of the overcap can then fall directly into the beverage cup during pouring due to the angle of the overcap in the open position. Any retained liquid ingredient that falls from the overcap onto the base can be confined within a ring on the base.
