Container of a fluid substance and a transport system therefor
A fluid container in the form of a can having a neck defining an opening, and fastened in a water-tight manner to the neck a valve element with a valve cup supporting a hollow stem movable against an elastic element between a first stable closing position and a second unstable position for delivering fluid through a cavity in the stem, the cavity communicating with the interior of the can in a dispensing position, the can being fixed to a support base of the container, the base comprising a support surface with a recess defined by a first centering surface to center the container on a valve cup of an identical container, on top of which the container may be placed, a second support surface for supporting the container on the valve cup, and a third recessed surface to house the stem of an aerosol valve of the further container.
1. Container ( 1 ) of a fluid substance, comprising a can ( 2 ) having a neck ( 4 ) defining an opening ( 3 ), a valve element ( 5 ) comprising a valve cup ( 6 ) supporting a movable hollow stem ( 7 ) against an elastic element ( 8 ) between a first stable closing position and a second unstable position of fluid delivery through a cavity ( 7 A) of the stem ( 7 ), the cavity ( 7 A) of the stem, when the stem is in the dispensing position, being in communication with the interior of the can ( 2 ), characterized in that the can ( 2 ) is fixed to a support base ( 10 ) of the container ( 1 ), the base comprising a support surface ( 14 ) provided with a recess ( 11 ) defined by a first centering surface ( 11 A) configured to center the container ( 1 ) on a valve cup ( 6 ) of a further identical container on which the container ( 1 ) can be piled on, by a second support surface ( 11 B) of stable support of the container ( 1 ) on the valve cup ( 6 ) and by a third surface ( 12 ) recessed with respect to the second surface ( 11 B) configured to house, protecting it, the stem ( 7 ) an aerosol valve of the further container ( 1 A).
2. Container ( 1 ) according to claim 1 , wherein the first surface has a truncated cone shape ( 1 B) and/or wherein the third surface ( 12 ) has a truncated cone shape.
3. Container according to claim 1 , wherein the third surface ( 12 ) comprises windows ( 13 ) configured to cooperate with a container rotation tool during soldering of the valve cup to the container.
4. Container according to claim 1 , wherein, from the support surface ( 14 ) of the base, extends a cylindrical skirt ( 15 ) provided at one end of a protruding edge ( 16 ) configured to cooperate with a groove ( 18 ) of the can for the snap fixing of the base ( 10 ) to the can ( 2 ).
5. Container according to claim 1 , wherein the can has a bottom end ( 2 A) opposite the opening ( 3 ) provided with a hemispherical conformation.
6. Container according to claim 1 , wherein at least part of a surface of the side of the container and of a lateral base of the base are wound by the same plastic film coating (R), said coating stabilizing the snap coupling between the base and the can.
7. Container according to claim 1 , wherein the cavity ( 7 A) of the stem, when the stem is in the dispensing position, is in communication with a deformable bag housed in the can ( 2 ) and sealed to the valve element ( 5 ).
