A vessel includes a memory and a processor operatively coupled to the memory. The memory is configured to store a vessel identifier. The processor is configured to initiate a timer for a shelf life of a solution placed into the vessel. The processor is also configured to conduct a measurement of the solution using one or more sensors in the vessel. The processor is also configured to compare the measurement to a threshold for the solution. The processor is further configured to activate a solution indicator to indicate that the solution should be discarded responsive to a determination that the shelf life has expired or a determination that the measurement exceeds the threshold.

An all-plastic self-locking pump includes a pump body extending into a bottle, provided with a pump chamber and connected with a bottle locking cover, a suction assembly is arranged in the pump chamber, a check valve is arranged at a lower end of the pump chamber. A button is connected to an upper end of the suction assembly, a self-locking cover is arranged on the pump chamber, a plastic annular part is arranged in the pump chamber above the check valve, and an opening is formed in a side face of the plastic annular part. Positions where the button stays include a locking position and an unlocking position, a locking mechanism is arranged between the button and the self-locking cover, and after the button is rotated to the unlocking position from the locking position, the button can be pressed to enable liquid in the bottle to be sprayed out of an outlet of the button. According to invention, the plastic annular part is arranged in the pump chamber and located above the check valve, the plastic elastic part replaces a metal spring to achieve elastic expansion and contraction, all parts are made of all-plastic materials, and energy conservation and environment friendliness are achieved; and when the button is not used, the button can be locked by rotating the button, so that liquid leakage caused by mistakenly pressing the button is prevented.

The invention discloses a pump with a left and right locking structure and an external spring, which includes a pump body extending into a bottle body, a pump chamber is arranged on the pump body, a locking bottle cover is connected to the pump body, a pumping member is arranged in the pump chamber, a locking cover is provided at an inner wall of the pump chamber, a one-way valve is provided at a lower end of the pump chamber, a bent nozzle is provided at an upper end of the pumping member, a liquid guiding pipe capable of extending into the bottle body is arranged on the pump body and located below the one-way valve, the pumping member includes a pump rod, a liquid inlet hole is formed below the pump rod, a piston is sleeved on the pump rod, an air inlet hole is formed in the pump body, a pushing part is arranged on the pump rod, the locking cover is further provided with a limiting protruding block, and a reset spring is arranged between the locking cover and the bent nozzle; and a limiting member capable of preventing the bent nozzle from being pressed downward when the pump rod is rotated by a certain angle is arranged between the pump rod and the locking cover. According to the invention, the bent nozzle can be prevented from being mistakenly pressed in a transportation process by arranging the limiting member, leakage is avoided, meanwhile, the air inlet hole is sealed through cooperation of the piston and the locking cover, and a sealing effect is enhanced.

A foamer for use in dispensing a dosage of a product which has a foam consistency is disclosed. The foamer is described as having a high output and as being a mini foamer such that the associated pump engine is able to deliver a dosage for each stroke which is in excess of that dosage normally associated with mini foamers. The receptacle to which the pump engine is assembled has a neck finish which is smaller than those neck finishes normally associated with higher output foamers. The resulting combination as set forth herein is to provide a higher output dosage without changing the size benefits and preferences of a mini foamer.

A nasal spray device can include housing having a sensor and a nozzle having a housing interface with a graphical image thereon. The sensor can be configured to sense movement of the graphical image when the nozzle moves relative to the housing, for instance during administration of medicine from the nasal spray device. The sensor can include an infrared proximity sensor that senses infrared reflectivity from the graphical image. The infrared proximity sensor can also be used to measure distance to a surface of a vial within the housing to thereby detect insertion of the vial into the housing.

A fluid dispenser including a body, a chamber coupled to or formed as part of the body and configured to contain a quantity of fluid, and a piston coupled to the body and rotatable within the chamber to different position. The piston is movable relative to the chamber in a first direction along an axis to draw fluid into the chamber, and the piston is movable relative to the chamber in a second direction opposite the first direction to discharge fluid from the chamber. The piston has stroke lengths that are selectable via the different rotational positions of the piston and that are associated with metered quantities of fluid to be drawn into the chamber. An anti-reversal feature is disposed between the piston and the body. The anti-reversal feature inhibits reversal of the piston during movement of the piston in the first direction or the second direction.

A child-proof discharger for media includes a reservoir, a pump part mounted on the reservoir and an actuable discharge portion mounted on the pump part. The discharge portion guided in an axially displaceable manner on a carrier part disposed on the closure element and can be locked with the aid of manually actuable spring bars. The spring bars are configured on an actuating plate configured on the discharge portion, and respectively have an inner tongue, which can be bent radially inwards relative to an inner wall of the carrier part. Each spring bar is respectively assigned a guide ramp as an entry curve to a contact area that is bounded by radial latches of the blocking setting upon a rotary motion of the discharge portion.
