A chemical dispensing system for delivering a chemical dose into a water resource is provided herein. The system includes a dispensing housing, a support feature, and an electrical circuit. The dispensing housing includes at least one compartment that is adapted to retain a chemical dose. The compartment is substantially sealable from an ambient environment that is outside of the compartment. The compartment is independently openable and closable to directly expose the compartment to the ambient environment and enable release of contents retained therein in the open position and to substantially prevent release of the contents retained therein in the closed position. The support feature facilitates suspension of the dispensing housing above a surface of the water resource. Opening of the compartment is controllable through the electrical circuit.

Silicone-containing cartridges having a plunger at one end thereof are effectively sealed against moisture penetration by introducing a silicone oil composition having a viscosity of from 5000 mPa.Math.s to 100,000 mPa.Math.s between the walls of the plunger and the interior surface of the cartridge wall.

A storage container includes: a sidewall portion, a seal portion and a movable member. The sidewall portion, the seal portion and the movable member define an accommodation space. The seal portion is adapted to seal a top of the sidewall portion, and the seal portion is provided with a hole communicated with the accommodation space. The movable member is adapted to seal a bottom of the sidewall portion, and further adapted to move up and down in parallel to a direction of the bottom of the sidewall portion pointing to the top. The movable member is configured to connect a control device. The control device controls the movable member to move up and down in a direction of the bottom of the sidewall portion pointing to the top.

A dispensing container with a cutter, in which a storage part can be used as a refill. A dispensing container 100 with a cutter 54 includes a storage part 1, a helical tube 2, a rotating lid 5, and a movable plate 3. The storage part 1 has a tubular shape with an opening at a top and is configured to contain a solid material. The helical tube 2 has a helical groove on an outer peripheral surface thereof, and is configured to be attached to a bottom surface of the storage part. The rotating lid 5 is disposed to be horizontally rotatable and includes a top plate 51 and a peripheral wall 52 that is a side surface. The top plate 51 is provided with the cutter 54 on an underside thereof and has an outlet 53. The cutter 54 is configured to cut the solid material into a thin piece, and the outlet 53 is configured to discharge the cut thin piece of the solid material. The movable plate 3 has a hole into which the helical tube is fitted, and is configured to be raised within the storage part in conjunction with rotation of the rotating lid. The top plate 51 of the rotating lid has a fitting projection 55 that extends downward to be inserted into an upper end of the helical tube 2 so as to cause the helical tube 2 to rotate together with the rotating lid.

Provided is a multi-use container. The container can be used for drinking a liquid by sucking a nipple to actuate one-way valve. Alternatively, the container can be used as a dildo by using a glans shaped cap. The container can be used to drink liquids from all sorts of angles. The container can also include a piston.

Systems and methods of bun handling include a cassette with opposed side walls. The cassette includes a front wall, an open rear face opposite the front wall, and a floor between the opposed side walls. A cover extends between the opposed side walls above the floor. The cover is movable relative to the opposed side walls and the floor. A slot is defined through the floor from the open rear face in a direction towards the front wall.

A piston for a collapsible cartridge for dispensing a material, the piston includes a rigid portion and a flexible portion. The rigid portion has a first diameter, a first end and a second end. The first end is configured to be disposed in a material dispensing direction. The flexible portion has a second diameter less than the first diameter, a first end disposed in the material dispensing direction and a second end disposed in an opposite direction. The flexible portion is disposed on the first end of the rigid portion such that the second end of the flexible portion is disposed to face the first end of the rigid portion. The flexible portion is configured to radially expand and longitudinally compress upon a force applied to the first end of the flexible portion to compress the collapsible cartridge between the flexible portion and an interior surface of a support cartridge.

An elastic member for a pump assembly is provided. The elastic member may include an upper support; a lower support provided under the upper support; and a connection part which connects the upper support and the lower support, and in which peaks and valleys are repeatedly formed in an outward direction to be bent when the elastic member is pressurized.

Embodiments of the present application provide a squeezing device, a photoresist supply system, and a photoresist supply method. The squeezing device comprises: a base, configured to bear a photoresist bottle; a support rail, vertically arranged on the base; a squeezing structure, an end of the squeezing structure is movably arranged on the support rail so that the squeezing structure moves up and down along the rail direction of the support rail; and a driving module, configured to drive the squeezing structure to deform the squeezing structure so as to reduce the area of a region enclosed by the squeezing structure, and also configured to drive the deformed squeezing structure so that the squeezing structure moves up and down along the rail direction of the support rail. By squeezing the photoresist bottle by the squeezing device, the utilization rate of the photoresist in the photoresist bottle is improved.

An emptying device for emptying a viscous material in a bubble-free manner out of a removal opening of a cartridge involves extruding a plurality of thin strands of the material. The emptying device includes a collecting container mounted to a base frame and a cartridge carrier that moves in a pressing direction towards the base frame. A cartridge plunger is adapted to push a pusher of the cartridge in the pressing direction. A discharge drive drives the cartridge plunger. A distributing head divides the viscous material exiting the removal opening into the plurality of thin strands. The distributing head is fastened to the removal opening and is adapted to move axially in the collecting container in the pressing direction. A vacuum housing connects in an air-tight manner to the collecting container and to an outer circumference of the cartridge even while the cartridge moves relative to the first vacuum housing.
