The ball is formed of a frangible material for shattering on impact with the ball stop, so as to dispense the surfactant, causing foaming when mixing with well fluid. Struts within the ball extend across an interior of the ball and join to inner surfaces of the ball. The struts are formed of a solid surfactant material. The ball has a spherical shape with dimples formed in an exterior surface of the sphere. A spring in the passage applies an upward force on the ball stop. The ball stop has upper and lower grids extending across the passage.

  • Publication number: 20150027477
    Abstract: [Problems] The present invention provides a filter containing built-in capsule in which a tobacco flavor enhancing liquid that can enhance flavor aspects such as taste, aroma, and richness is encapsulated, along with a cigarette and cigarette substitute comprising this filter. [Resolution means] The cigarette in which filter containing built-in capsule 1 according to the present invention is incorporated includes cut leaf 2, rolling paper 3, filter 4, and tip paper 5, with easily breakable capsule 6 incorporated in filter 4, and tobacco flavor enhancing liquid 8 including natural cacao extract encapsulated in film 7. When smoking, by pinching the filter part to crush capsule 6, film 7 bursts, causing tobacco flavor enhancing liquid 8 to ooze into filter 4 and enabling enhancement of the taste, aroma, richness, etc. specific to tobacco.

  • Publication number: 20140196729
    Abstract: A cigarette filter subassembly is manufactured from a filter member having absorbent material encased within an outer cover. A plunger is passed axially through the absorbent material such that a pointed leading end of the plunger displaces the absorbent material radially outwardly against the cover to form a liner of compressed absorbent material along the cover's inside surface. An inner surface of the liner surrounds a hollow axial opening which is to receive absorbent members and capsules inserted axially therein. The capsules are adapted to be broken by a smoker to release an additive material which modifies characteristics of tobacco smoke. An outer cylindrical surface of the plunger optionally carries a transferable binder material that becomes smeared onto the inner surface of the liner to form thereon a coating which is impermeable to the additive material released from the capsule.
