Abstract
The outer container 1 presents a series of air-admission orifices in a zone 6. The skirt 12 of the inner pouch 8, between its line 11 of fastening to the outer container 1 and its open end 10, constitutes a valve for closing the series of orifices in the event of manual squeezing being applied on the outer container 1.
Claims11
A device for packaging viscous substance and for emptying by manual pumping, the device comprising:
- an elastically deformable outer container of generally cylindrical shape, having an open first end with a shoulder in the form of a truncated cone and a neck suitable for receiving a closure cap, and having a second end that is suitable for being sealed;
- and
- a flexible inner pouch of generally cylindrical shape, having a closed first end and an open second end;
- said pouch being fastened inside said outer container along an annular fastening line placed in such a position that, at the end of the device being emptied, said closed first end bears against said shoulder;
- wherein between said annular fastening line and its open second end, said pouch constitutes a skirt that is held solely by the annular fastening line and that covers an annular zone on the inside of the outer container;
- in the annular zone covered by said skirt, the outer container presents a series of air-admission orifices for admitting air into the inside of the outer container;
- and said skirt constitutes a valve ensuring that said series of orifices is closed in the event of manual squeezing being applied on the outer container.

A method of preparing a device for packaging viscous substance and for emptying by manual pumping, said device having;
- an elastically deformable outer container of generally cylindrical shape having an open first end including a shoulder in the form of a truncated cone and a neck suitable for receiving a closure cap, and a second end that is open;
- and a flexible pouch of generally cylindrical shape with a closed first end and an open second end;
- said method comprising the steps of:
- a) forming air-admission orifices in an annular zone of the outer container;
- b) inserting the pouch inside the outer container and pressing it against the outer container, the closed first end of the pouch pressing against the shoulder of the outer container, and the open second end of the pouch being situated between said annular zone and said second end of the outer container;
- and
- c) fastening the pouch to the outer container along a fastening line situated between said annular zone and said first end of the outer container.
