Abstract

The invention relates to a container ( 1 ), such as a tub ( 5 ) for a cosmetic product, including: a base ( 10 ); a cover ( 20 ) which is arranged so as to be closed on the base ( 10 ); and a deformable pad ( 30 ) arranged between the base ( 10 ) and the cover ( 20 ), said pad ( 30 ) including a shell ( 33 ) and a seal ( 40 ) forming a sealed enclosure, as well as a fluid ( 36 ) contained in the shell, the pad ( 30 ) being arranged so as to apply a load onto the base ( 10 ) via the seal ( 40 ) when the cover ( 20 ) is closed on the base ( 10 ).

First claim

The invention claimed is:

the shell ( 33 ) comprises an upper part ( 32 ) and a lower part ( 34 ) joined to the upper part ( 32 ), the upper part ( 32 ) and the lower part ( 34 ) comprising a central hub ( 32 c ) and a complementary shaft ( 34 c ) adapted to cooperate with the central hub ( 32 c ) in order to join the lower part ( 34 ) to the upper part ( 32 ).

2. The container ( 1 ) according to claim 1 , in which the fluid ( 36 ) is at a pressure equal to or greater than atmospheric pressure.

3. The container ( 1 ) according to claim 1 , in which the seal ( 40 ) is made of a deformable resilient material selected from the group consisting of a thermoplastic elastomer, styrene-ethylene-butadiene-styrene (SEBS) and silicone.

4. The container ( 1 ) according to claim 1 , in which the shell ( 33 ) comprises an upper part ( 32 ) and a lower part ( 34 ) joined to the upper part ( 32 ), and the seal ( 40 ) is overmoulded onto the upper ( 32 ) or lower ( 34 ) part of the shell ( 33 ) or is dual-injected therewith.

5. The container ( 1 ) according to claim 1 , further comprising a swivel joint (R) between the lid ( 20 ) and the upper part ( 32 ) of the pad ( 30 ) or between the upper part ( 32 ) of the pad and the lower part ( 34 ) of the pad.

6. The container ( 1 ) according to claim 1 , in which the base comprises a mouth ( 12 ) with an internal wall ( 12 a ), and the seal ( 40 ) is disposed at the periphery of the shell ( 33 ) and applies the load to the internal face of the mouth ( 12 ).

7. The container ( 1 ) according to claim 6 , in which the internal wall ( 12 a ) of the mouth ( 12 ) is shaped as a shoulder ( 12 c ).

8. The container ( 1 ) according to claim 1 , in which the base comprises a mouth ( 12 ) with an upper edge ( 12 b ), and the seal ( 40 ) is disposed on a lower face of the shell ( 33 ) and applies the load to the upper edge ( 12 b ) of the mouth ( 12 ).

9. The container ( 1 ) according to claim 8 , in which the pad ( 30 ) comprises a lower part ( 34 ) consisting of a plate ( 34 a ) and a border ( 34 e ) running along the periphery of the plate ( 34 a ), and separated therefrom by a traversing passage ( 34 f ) intended to accommodate the seal ( 40 ).

10. The container ( 1 ) according to claim 9 , in which the seal ( 40 ) is shaped as an omega channel ( 40 a ), the omega channel comprising arms ( 40 a ′) that are fixed to the border ( 34 e ) and to the plate ( 34 a ) respectively, and a base ( 40 a ″) that extends towards the upper edge ( 12 b ) of the mouth ( 12 ) forming a shoulder.

11. The container ( 1 ) according to claim 10 , in which the seal ( 40 ) further comprises a resilient lip ( 40 b ) extending radially outwards from the seal ( 40 ), adapted so that it comes into lateral contact with the upper edge ( 12 b ) in such a way as to provide a diametral seal with the tub ( 1 ).

12. A container such as a tub for a cosmetic product ( 5 ), comprising
a base ( 10 );
a lid ( 20 ), arranged in order to be closed on the base ( 10 ); and
