In one embodiment, the applicator element 84 is compressed against the intermediate receiving surface 61 when the applicator 80 is placed on the product dispensing assembly 110.

(39) According to an aspect of the present embodiment and as shown in FIG. 5, when the applicator 80 is received inside the annular sleeve 70, a distal end surface 82a of the handle 82 abuts a top edge 63c of the upper skirt 63a of the dispensing head 60 so that when a downward push is applied on the handle 82 of the applicator 80, the applicator 80 and the dispensing head 60 both slide in downward direction within the outer sleeve 70 to actuate the pump assembly 50.

(40) To use the device 100, the user disengages the cap 40 and actuates the pump 50 by applying downward push force to the dispensing head 60 with the applicator 80. For example, the user firmly grips the outer container 10 and pushes the applicator 80. When fully actuated, the stem 5 is depressed and a dose of product contained in the inner container 20 is delivered. The product leaves the inner container 20 via the pump assembly 50, the product passageway 62a and the outlet 62, and is dispensed onto the intermediate receiving surface 61. The dispensed product then comes into contact with the applicator element 84. The product is transported along the intermediate receiving surface 61 partly by capillary action and/or by pressure.

(41) The user then removes the applicator 80 from the upper chamber 72 of the annular sleeve 70. In one embodiment, the applicator 80 is a block of foam that is slightly compressed when the cap 40 is on the product dispensing assembly 110. For this embodiment, the block of foam/sponge 84 expands upon removal of the cap 40 from the product dispensing assembly 110, thereby facilitating the pumping out of some of the product that might not have been absorbed when the cap 40 was closed. This expansion of the applicator element 84 also makes it possible for at least a portion of the applicator element 84 to be placed back in contact with the intermediate receiving surface 61 for loading and/or reloading of the product onto the applicator element 84 when the cap 40 is not on the product dispensing assembly 110. To load the product, the applicator element 84 is placed in contact with the intermediate receiving surface 61 and the stem 5 is actuated by moving the dispensing head 60 towards the inner container 20.

(42) The user preferably exerts slight pressure on the applicator element 84 to expel the product from the pores of the applicator element 84, thereby transferring it to the surface to be treated. Before being repositioned, the applicator element 84 of the applicator 80 may be washed in a cleaning solution (e.g., under tap water) to clean it.

(43) Additionally, the inner container 20 may not be made in a single piece and may comprise a tubular body whose lower end is closed by a separate bottom plug 26, as shown in FIGS. 5 and 6.

(44) According to an aspect of the present disclosure, the cap 40 snap fits on the annular sleeve 70 of product dispensing assembly 110. More particularly and as shown in FIG. 3, the cap 40 comprises an annular bead 43 on an inner surface thereof that snaps onto at least one corresponding projection 75 provided on an outer surface of the annular sleeve 70. However, in alternate embodiments the cap 40 may be coupled with annular sleeve 70 by any other means of coupling such as magnetic, threads etc.

(45) It should be understood that the foregoing description is only illustrative of the present disclosure. Various alternatives and modifications can be devised by those skilled in the art without departing from the disclosure. Accordingly, the present disclosure is intended to embrace all such alternatives, modifications and variations that fall within the scope of the appended claims.
