Device for dispensing a product, particularly product samples, as a spray

A device for containing and spraying a product comprising:

• a reservoir containing the product, said reservoir including at least one flexible wall;
• a diffuser coupled to the reservoir for spraying the product, said diffuser including an anti-air-intake element that prevents air from entering said reservoir through said diffuser;
• and
• wherein application of pressure to said at least one flexible wall forces said product through said diffuser to be sprayed from said diffuser, and wherein when the application of pressure ceases air is prevented from entering said reservoir by said anti-air-intake element,
• wherein said diffuser includes a nozzle having at least one outlet, and wherein said diffuser further includes at least one swirl channel, and
• wherein said diffuser includes a stud and said at least one swirl channel is at least partially defined between said stud and said nozzle.

A device for containing and dispensing a product comprising:

• a container containing the product, said container including a container volume which is at least partially defined by at least one flexible wall having an inner surface and at least one exposed outer surface on an exterior of said container, wherein said inner surface is in contact with said product and said at least one exposed outer surface is exposed to a user's touch;
• a dispensing head coupled to said container, said dispensing head including a one-way valve such that said product can pass from said container and through said dispensing head to exit said container but air is prevented from entering said container through said dispensing head, wherein said one-way valve comprises a movable member having a fixed inner portion and an outer peripheral portion movable from a closed position to an open position;
• and
• wherein application of pressure by said user to said at least one exposed outer surface deforms said at least one flexible wall to pressurize the product disposed in said container and said product passes through said dispensing head by way of said one-way valve in said open position to exit said container, and wherein when application of said pressure to said at least one exposed outer surface is stopped air is prevented from entering said container by said one-way valve in said closed position and said at least one flexible wall is maintained in an at least partially deformed state.

A device for containing and dispensing a product comprising:

• a container containing the product, said container including a container volume which is at least partially defined by at least one flexible wall;
• a diffuser coupled to said container, said diffuser including:
• a nozzle,
• a stud,
• at least one swirl channel at least partially defined between said stud and said nozzle, and
• a one-way valve such that said product can pass from said container and through said diffuser to exit said container but air is prevented from entering said container through said diffuser;
• and
• wherein application of pressure to said at east one flexible wall deforms said at least one flexible wall to pressurize the product disposed in said container and said product passes through said diffuser by way of said one-way valve to exit said container, and wherein when application of said pressure to said at least one flexible wall is stopped air is prevented from entering said container by said one-way valve and said at least one flexible wall is maintained in an at least partially deformed state.

A device for containing and dispensing a product comprising:

• a container containing the product, said container including a container volume which is at least partially defined by at least one flexible wall;
• a dispensing head in communication with said container via a channel oriented along a first axis of said dispensing head, said dispensing head defining a housing in communication with said channel and including a stud extending inside said housing along a second axis of said dispensing head perpendicular to said first axis, said housing defining an orifice for dispensing said product, said orifice being positioned on said second axis,
• said dispensing head further including a one-way valve between said channel and said housing such that said product can pass from said container and through said dispensing head to exit said container but air is prevented from entering said container through said dispensing head;
• and
• wherein application of pressure to said at least one flexible wall deforms said at least one flexible wall to pressurize the product disposed in said container and said product passes through said dispensing head by way of said one-way valve to exit said container, and wherein when application of said pressure to said at least one flexible wall is stopped air is prevented from entering said container by said one-way valve and said at least one flexible wall is maintained in an at least partially deformed state.
