An apparatus, system and method for regulating fluid flow are disclosed. The apparatus includes a flow rate sensor and a valve. The flow rate sensor uses images to estimate flow through a drip chamber and then controls the valve based on the estimated flow rate. The valve comprises a rigid housing disposed around the tube in which fluid flow is being controlled. Increasing the pressure in the housing controls the size of the lumen within the tube by deforming the tube, therefore controlling flow through the tube.

Disclosed are multi-chamber containers and methods of using the same. The multi-chamber container includes a base and a wall extending upwardly from the base. The wall is longitudinally divided into a top section and a bottom section. The multi-chamber container also includes a partition disposed between the top and bottom sections of the wall for separating a first volume from a second volume. The partition includes at least one deformation region, and the partition is configured to deform about the deformation region in response to a trigger.

The present invention concerns a flexible package which is designed to contain a product, for instance a spice or a cosmetic product, wherein the flexible package is joined together to create a closed package. A dosage device is further arranged on an inner face of the closed package, said dosage device comprising an elastic dosage membrane, which elastic dosage membrane, over at least a part of its width and length, is provided with a number of incisions.

The invention is a nail polish bottle that comprises a bottle body and a bottle opening. The bottle body comprises an open end and an accommodating space. The open end and the accommodating space are connected. The bottle opening comprises an interconnecting piece with an attached hollow tube. The interconnecting piece can be detached from and attached to the open end of the bottle body, and the hollow tube of the interconnecting piece connects to the accommodating space of the bottle body. This invention of the nail polish bottle allows the nail polish in the bottle body to be dripped onto users' nails through the hollow tube of the bottle opening for nail painting. This resolves the issue presented by current nail polish container bottles where nail polish cannot be directly dripped onto the nails of the users for nail painting.

The present disclosure provides a container and a process for producing the container. In an embodiment, the process includes placing a sleeve bag on valve assembly (SBoV) in a blow mold apparatus. The blow mold apparatus has two opposing and movable molds. The SBoV has a valve seat. The process includes extending a parison of flowable polymeric material around the SBoV and between the opposing molds. The process includes moving the opposing molds to a closed position and pressing an upstream portion of the parison against the valve seat. The process includes blow molding a downstream portion of the parison into a container-shape within the closed mold. The process includes forming a container with the valve seat melt bonded to a neck portion of the container.

A flow meter includes an image sensor and a processor. The image sensor is configured to capture an image of a drip chamber. The processor is configured to determine whether the captured image of the drip chamber contains a match to a template, and to apply a blurring function to the image captured by the image sensor of the drip chamber such that the processor can determine if the captured image contains a match to the template.

The invention relates to a cleaning product including an inverted container assembly comprising an inverted container and a liquid dispenser attached to a bottom surface of the inverted container, and a viscous cleaning composition contained in the inverted container assembly. The present invention also relates to the use of the cleaning product for cleaning dishware.

The present disclosure provides a dispenser for pressurized material. In an embodiment, the dispenser for pressurized material includes a container half having an exposed edge and a closure member at the exposed edge. The container half has a cup half in an interior top portion. The dispenser includes a reciprocal container half having a reciprocal exposed edge and a reciprocal closure member at the reciprocal exposed edge. The reciprocal container half has a reciprocal cup half in an interior top portion. The closure member and the reciprocal closure member matingly engage along the exposed edges to attach the container half to the reciprocal container half and form a container. The dispenser includes a sleeve bag on valve (SBoV) assembly in an interior of the container. The SBoV assembly includes a valve seat. The cup and the reciprocal cup support the valve seat to secure the SBoV assembly in the container.

A container for dispensing a liquid includes a body and a piercing device. The body includes an interior storage volume, an outlet through the first wall for dispensing the liquid, a first track disposed in a first side wall of the body, and a second track disposed in a second side wall of the body, the second side wall opposite the first side wall. The piercing device can be slidably coupled to the body and includes a first rail configured to slide within the first track, a second rail configured to slide within the second track, and a piercer that includes a piercing end. The piercer can slide from a first position to a second position to pierce the body and create a vent opening.
