A plastic aerosol container includes a main body portion that is constructed and arranged to withstand aerosol pressurization within a range that is about 50-300 psig. The plastic aerosol container also includes a finish portion that is unitary with the main body portion. The finish portion may be threaded or unthreaded. The finish portion has a side wall, an upper sealing surface, at least one helical thread and a support ledge beneath the helical thread. Reinforcement structure is positioned beneath the support ledge for reinforcing the finish portion against deformation due to the pressurization. A method of stabilizing a plastic aerosol container is also disclosed.

Canisters are provided that include a cylindrical body and a cap welded to the body to define a cavity filled with carbon dioxide or other fluid. The canisters may be loaded into a medical device, e.g., to provide an energy source for operating the device. Methods for making such canisters are also provided.

A method of charging a container for use in a medication delivery apparatus wherein the propellant used comprises 1,1-difluoroethane (R-152a) is described.

Filling device for filling an aerosol container with a liquid, such as paint, which device comprises a cup for the liquid for the aerosol container, which cup is provided with an injection opening at its bottom surface; a pusher element for pushing the liquid from the cup via the injection opening to the aerosol container; and a piston head that is adapted to be detachably fixed on the end of the pusher element to be in contact with the liquid in the cup when the liquid is transferred from the cup to the aerosol container, which piston head is in the form of a scrap-er in continuous contact with the side wall of the cup during the liquid transferring operation, wherein the detachable fixing of the piston head allows the piston head to be withdrawn together with the pusher element from the cup after the liquid transferring operation is done.

An apparatus is provided that is configured to be used with a container having contents to permit mixing of the contents of the container. The apparatus includes a main body having a geometrical shape having an open end, a closed end, and a longitudinally extending bore or opening extending from the open end to the closed end. The opening or bore is configured to receive at least a portion of a container. A shaft is generally orthogonally positioned from a portion of the closed end. The shaft is configured to be received by a rotational device. The mixing apparatus can be used to mix various sized containers containing contents having one or more materials to be mixed.

A non-addictive analgesic sustained-release drug delivery system, comprising: (1) a narcotic analgesic drug having a concentration of 1 mg/ml-160 mg/ml, the drug being selected from a group consisting of: a local analgesic drug, and the combination of the local analgesic drug and a nonsteroidal analgesic drug and/or an opioid analgesic drug; (2) a drug menstruum in a proportion of 1%-75% (v/v), the menstruum being selected from a group consisting of benzyl alcohol, ethanol, benzyl benzoate, ethyl lactate, and tetrahydrofurfuryl polyethylene glycol ether; and (3) a drug sustained-release formulation having a proportion of 25%-99% (v/v), the sustained-release formulation being selected from a group consisting of natural vegetable oil, synthetic lipid, artificially improved half-natural lipid and derivative thereof. Also disclosed are a preparation process and use of the sustained-release drug delivery system.

An assembling apparatus efficiently performs a recovery operation and a parts size change operation. A filling line (the assembling apparatus) has parts supply units that supply parts, assembling units that mount one of the parts to another part, and a conveying unit that individually moves carriers 12 capable of storing parts constituting an assembly. The parts supply units are provided at positions away from the assembling units, the assembling units are accommodated in an isolator having an interior maintained in an aseptic state, and gloves to perform an operation on the assembling units are provided on a side surface of the isolator. The supply units store the parts in one of the carriers, the carrier then moves into the isolator, and the assembling units take the part from the carrier, and mounts the part to the other part stored in the same carrier.

The invention comprises an apparatus and a method for amending a food product, comprising the steps of: (1) receiving into a second geographic zone the food product from a first geographic zone, where packaging greater than five milligrams per serving of tetrahydrocannabinol in the food product is: (a) illegal in the first geographic zone and (b) legal in the second geographic zone; (2) forming a composition of the tetrahydrocannabinol comprising a viscosity of less than 2,000 mPa.Math.sec; (3) injecting the food product with the composition of tetrahydrocannabinol to form an amended food product; and optionally (4) forming an emulsion of the tetrahydrocannabinol, an emulsifier, and water, the emulsion comprising, excluding particle sizes of less than 20 nm, a mean particle size of less than 1000 nm and a viscosity of less than 100 mPa.Math.sec.

The invention comprises a shampoo apparatus and method of use thereof, comprising: (1) a pressurized container, a pressure in the container in a range of seventy to two hundred pounds per square inch and (2) a shampoo in the container, the shampoo comprising greater than five thousand parts per million carbon dioxide, where the shampoo optionally contains a detergent, zinc pyrrolidone carboxylic acid, and/or minoxidil. The carbon dioxide in the container is optionally added as a solid or a liquid and/or is chemically formed inside the container, such as from any of a carbonic acid, a bicarbonate, a bicarbonate salt, and/or a carbonate. The carbon dioxide solvates/makes soluble and aids removal of sebacic acid on the scalp.

The invention comprises a method of making and/or using a shampoo, comprising the steps of: placing shampoo into a container; combining a carbon dioxide precursor with the shampoo; sealing the container to yield a sealed container; and forming carbon dioxide inside the sealed container from the carbon dioxide precursor, the carbon dioxide formed in the sealed container comprising a concentration of greater than one thousand parts per million. Optionally and preferably, the sealed container includes a finger operated valve to release the shampoo from the container and at least one of a carbonic acid, a bicarbonate, and/or a carbonate as the carbon dioxide precursor, where a reaction forms at least one-half of dissolved carbon dioxide in the sealed container.
