A telescoping syringe suitable for use with medications and other ejectable or injectable fluids is presented. The syringe includes a plunger, a barrel, and a valve. The plunger is extendible from and retractable into the barrel. The plunger defines a first reservoir. The barrel defines a second reservoir as the plunger is extended from the barrel. The valve is disposed at one end of the plunger adjacent to a nipple extending from the barrel. A first sealing interface is formed by the valve and a distal wall along the barrel adjacent to the nipple. A second sealing interface is formed by an annular flange along the one-way valve and an annular groove along the plunger. A third sealing interface is formed by the valve and a circumferential end along the plunger. The sealing interfaces are closed prior to extension of the plunger from the barrel thereby preventing a gas from entering and a fluid from existing the first reservoir. The sealing interfaces are open when the plunger is extended from the barrel so that the gas enters the first reservoir via an inlet(s) along the annular groove and fluid is communicated into the second reservoir via an outlet(s) along the valve. The second and third sealing interfaces are closed when the plunger is retracted into the barrel thereby allowing fluid to exit the second reservoir via the nipple.

Claw-skip mechanism with level adjustment enables products to be dispensed in tube form includes at least one stem within package body; sequential claws on stem; button enabling to push stem towards lid at adjustable amounts; at least one pusher moves towards lid together with stem as button is pressed pushing product towards lid opening; gasket providing pusher movement within package body without leaving residue; elastic extensions provide pusher to grab one-or-more claws and move, when stem moves towards lid providing pusher to skip one-or-more claws by stretching outwards when stem returns to initial position; at least two-levels and one counter-level positioned across each other on lid and base-lid; level-steps enabling formation of distances between level and counter-level as button or base-lid is turned; amount adjust to be dispensed from package opening to adjustable distance between level and counter-level; adjustment markers enabling levels to the button or base-lid for level adjustment.

A device has a first part with a valve seat and storage chamber, and a second part with a flexible valve cover and actuator. The storage chamber may be formed from a pre-form blow-molded into a flexible pouch defining a variable-volume storage chamber. The flexible valve cover and valve seat form a normally closed valve seam therebetween. The valve cover is movable in response to fluid at an inlet to the seam exceeding a valve opening pressure of the one-way valve between (i) a normally closed position with valve cover and valve seat in contact with each other and defining the normally closed seam, and (ii) a second position with at least a portion of the valve cover spaced away from the valve seat to allow the fluid to pass through the seam. The one-way valve may have anti-spritz features for using the device to dispense a substance, such as to the eye. The device may contain prostaglandins without the device material absorbing the prostaglandins material and/or without the material being adsorbed into the drug.

A preserving device for preserving a liquid fluid may include a container for storing the liquid fluid; a piston to engage the interior surface of the container and to move within the container to compress the liquid fluid; and a replaceable lid for the container to allow the liquid fluid to enter the container and to allow the liquid fluid to escape the container as the piston is moved within the container

A system and method determine color of skin of a subject and produce a customized cosmetic based at least in part on the determined color of skin. A region of skin is covered with a chamber having an open area facing the skin. The skin is illuminated with light caused to enter the chamber. The light is caused to be dispersed within the chamber. A camera is used to record an image of a portion of the dispersed light in the chamber and the recorded image is processed to characterize the color of the skin. The recorded image includes a plurality of colors which are mapped to the closest color recipe. The color recipe is used to calculate actuator displacements for a portioning machine that includes a cartridge having cosmetic additives that produce the customized cosmetic.

A dispensing container for viscous products features a cream pot having an inner cylinder defining a storage volume to store a viscous product; a cap closes the cream pot and has a dispensing outlet; a screw rod rotatably connects to the cream pot; a piston having an inner thread couples to the screw rod so rotation of the screw rod moves of the piston in the inner cylinder along a longitudinal axis of the screw rod to reduce the storage volume of the inner cylinder and dispense the product through the dispensing outlet; an indexing mechanism locks the screw rod in rotational positions with respect to the cream pot and has indexing spring elements located at the screw rod and indexing sections located at a bottom of the cream pot, the indexing spring elements interact with the indexing sections to lock the screw rod with respect to the cream pot.

A liquid dispenser includes a housing configured to receive a liquid supply cartridge, and a reservoir disposed in the housing that holds a volume of the product. The reservoir includes an access port for receiving the liquid supply cartridge and placing the liquid supply cartridge and the reservoir in communication. A dosing tank is connected to the reservoir and configured to hold a metered volume of the product. A control valve is movable between an opened position and a closed position, wherein when the control valve is in the opened position, product in the dosing tank is permitted to flow from the liquid dispenser and product flow from the reservoir to the dosing tank is prevented, and when the control valve is in the closed position, product in the dosing tank is prevented from flowing from the liquid dispenser and product flow from the reservoir to the dosing tank is permitted.

The present disclosure provides a curved surface coating device. The curved surface coating device includes a bracket having a first and second ends. The curved surface coating device includes a glue coating portion connected with the first end of the bracket. The curved surface coating device includes a transmission member connected between the first and second ends of the bracket and its distance from the first end of the bracket is adjustable. The curved surface coating device includes a first driving mechanism connected with the transmission member for driving the bracket to rotate about the transmission member as a center of rotation. The curved surface coating device includes a second driving mechanism connected with the bracket for driving the bracket to move on a line where the first end and the second end are located.

A dispenser assembly having a plunger and a housing is provided. The plunger has an inner plunger portion and an outer plunger portion disposed concentrically around the inner plunger portion. The housing has an inner tubular housing wall, an outer tubular housing wall, and first and second outlet members. The outer tubular housing wall is disposed concentrically around the inner tubular housing wall. The inner tubular housing wall defines a first interior region therein, and the inner tubular housing wall and the outer tubular housing wall define a second interior region therebetween. The first and second outlet members fluidly communicate with the first and second interior regions, respectively. The inner plunger portion is slidably received in the first interior region. The outer plunger portion is slidably received in the second interior region.
