The device for containing fluid substance to be dispensed by manually operated pump, for associating with a rigid container neck, includes a bag having body and neck from which connection flange extends transversally, and a ring cap including bag first connector having an annular connection body, presenting a longitudinal symmetry axis. The annular connection body has a lower portion having a diameter smaller than the bag flange external diameter, and bigger than or equal to the bag neck external diameter; and an upper portion having an annular seat open on the top, having a rest surface lying horizontally for the connection flange.;The connection body includes a substantially cylindrical wall and a guide element to guide at least a portion of the flange from a lower free edge of the connection body to the annular seat and prevent the flange (4) from slipping out of the annular seat. |

1. A device for containing a fluid substance, to be dispensed by a manually operated pump, and suitable to be associated with the neck of a rigid container, comprising:
a bag presenting a body comprising a bottom wall and a lateral wall, both of the bottom wall and the lateral wall being flexible, and a neck from which a substantially rigid connection flange extends transversally, and a ring cap element comprising first connection means of said bag presenting an annular connection body, presenting a longitudinal symmetry axis, wherein said annular connection body presents a lower portion having a diameter smaller than the external diameter of said flange of the bag, and greater than or equal to the external diameter of said neck of the bag to be able to house at least a portion of said neck of the bag therein, and an upper portion presenting an annular seat open at the top, presenting a rest surface lying horizontally for said connection flange, wherein said connection body further comprises at least one portion of a substantially cylindrical wall, said portion presenting all an equal distance with respect to said longitudinal symmetry axis, said wall extending beneath said annular seat, said wall comprising at least a guide element comprising at least a guide portion presenting a distance with respect to said longitudinal symmetry axis different with respect to said distance of the portion of the substantially cylindrical wall, said portion being suitable to guide at least a portion of said flange from a free lower edge of said connection body to said annular seat, wherein said guide element comprises means suitable to prevent said flange from slipping out of said annular seat once the flange has been guided therein, so said connection means fasten stably said bag to said ring cap element at least with respect to vertical movements or downwards rotatory movements of said bag with respect to the ring cap element. |
