A vented draining device configured to be affixed to an existing container, such as a plastic beverage bottle with a threaded neck finish. The vented draining device allows for the attachment of a tube for the connection of the draining device to a fluidic system for draining while venting air from the existing container. Apertures in the draining device provide venting for the exhaust of air which is displaced by the fluid which is drained into the container.

In some examples, a system includes a display and a computing device coupled to the display. The computing device includes a memory and one or more processors coupled to the memory, and the memory includes instructions that when executed by the one or more processors identify, based on at least an identity of a worker, one or more articles of PPE for the worker to use and display an avatar of the worker, where displaying the avatar includes equipping the avatar with the one or more articles of PPE.

A sprayer that produces the pressure for a fluid spray without the requirement of mechanical energy in the form of a manual or battery-powered compressor or fluid pump. The sprayer utilizes a handle and vent system incorporated into the bottle and a shut-off placed at the nozzle of a telescoping wand which work together to enable atmospheric pressure to produce the intended fluid flow and spray, and yet also employ a needed closed system to contain the fluid.

An apparatus for installing a valve in a hollow body. The apparatus includes a first member and a second member, wherein a part of lengths of the first and second members are complementary to each other to accommodate the first member circumferentially over the second member at the complementary part. The second member is configured to be inserted in a hole on an outer surface of the hollow body; advanced inside the hollow body while retaining the first member against the hole; and withdrawn from the hollow body while retaining the first member against the hole. The apparatus is configured to install the valve into the hollow body while the first member is retained against the hole, and wherein the first member is withdrawn upon the installation of the valve into the hollow body.

The invention discloses a check valve, a container and an oral irrigator. The check valve is made of an elastic material and comprises a valve body part with a hollow structure, wherein an opening communicated with the hollow structure is formed in the top of the valve body part, the valve body part comprises two opposite connection walls and two opposite membranes, two opposite sides of each connection wall are respectively connected to the two membranes, the tops of the two membranes are away from each other, and the bottoms of the two membranes abut against each other. The check valve has a leakage prevention function and a ventilation function. The check valve is simple in structure, easy to machine, low in production cost, small in size, good in structural stability and long in service life and occupies a small space.

A valve apparatus [11] for connection to a tank or pipe, the valve apparatus [11] comprises a housing [12], a first opening [176a] and a second opening [177a] communicating with respective first conduit [16] and second conduit [17] each for providing ingress and egress of fluid into and out of the housing [11] through the first opening [176a] and the second opening [177a], and discrete first and second valve means or valves [14; 15] which are spaced apart from one another, the first and second valve means or valves [14; 15] selectively controlling fluid flow between the first and second conduits [16; 17], wherein, in use, the principal flow axes along the first conduit [16] and second conduit [17] are parallel and opposed, the first valve means or valve [14]is configured to open when the pressure in the first conduit [16] is greater than a first pressure and the second valve means or valve [17] is configured to open when the pressure in the first conduit [16] is less than the first pressure.
