[0027] FIG. 9 is the view of FIG. 5, wherein the engagement is schematically and kinematically shown which is formed with the engagement members of FIGS. 8 and 8b;

[0028] FIGS. 10a, 10b are front views of two alternative versions of the device according to the invention.

[0029] The container according to the invention is of the conventional type, generically consisting of a tank 1, preferably covered with a decorating and protecting sleeve C, and of a closing capsule 2 with which a stem 3 is associated through suitable retaining means.

[0030] Tank 1 consists of a cylindrical body, at the top of which a neck 4 is provided, apt to the insertion of stem 3 into tank 1 and to the relative tightening of capsule 2. Neck 4 has on the outer surface thereof a shaped base crown 5, apt to define a rail 6 which skirts a series of retaining brackets 7, said rail 6 corresponding in certain portions to the top of said neck 4.

[0031] As can be seen from the drawings, the axis of said brackets 7 is perpendicular with respect to the axis of tank 1.

[0032] Capsule 2 consists of an external, ornamental, cylindrical hood 2a, which houses inside the actual capsule body 2b. As illustrated in FIGS. 6, 6a and 6b, it carries externally longitudinal notches 2c apt to the engagement with complementary grooves (not shown) provided within hood 2a. At the bottom of said capsule body 2b there is integrally provided a smaller-diameter cylindrical appendix 2d, along the outer surface of which an annular groove 2e is obtained.

[0033] From the top of the capsule body an elongated cylindrical crown (2f) projects internally, perforated at the distal end housing the top of said stem 3.

[0034] Stem 3, illustrated in FIGS. 7 and 7a, is of the type generically consisting of a central body 3a, surmounted at the proximal end by a trunco-conical tapering 3b supporting a collar 8, and which carries in turn at the distal end a trunco-conical tapering 3c for the housing of an applicator member (not shown). From said collar 8—axially with said stem 3—a cylindrical head member 9 projects.

[0035] Finally, to guarantee the movement and the engagement of capsule 2 with respect to container 1, a rotating ring 10 is provided, as illustrated in FIGS. 8, 8a and 8b, consisting of a cylindrical ring of a diameter substantially identical to said collar 8, from the inner surface of which at least a peg 11 projects. Preferably, the pegs are at least two, and even more preferably they are three or four, depending on the number of brackets 7 provided on the neck of tank 1.

[0036] In order to keep capsule 2 connected with rotating ring 10 and stem 3 there is provided a cylindrical coupling ring 12, internally provided with protruding notches 12a having a semi-toroidal profile. Protruding notches 12a have such a diameter as to be able to be inserted by pushing into the annular groove 2e of capsule 2. Moreover, in order to keep rotating ring 10 in position, coupling ring 12 has, at the distal end thereof, an annular abutment recess 12b (FIGS. 6, 6b).

[0037] Arranged between collar 8 and capsule body 2b there is a spring 13 apt to guarantee the quick and automatic release movement of capsule 2 in the operation of the container, as will be better understood from the following explanation.

[0038] In order to improve product quality, and to reach the set objects, it has been furthermore provided to insert a cylindrical scraper 14, known per se in the art, into neck 4.

[0039] Preferably, a gasket 15 made of plastic material is also provided, apt to align capsule 2 with respect to tank 1.

[0040] Preferably, sleeve C extends in height until it covers from view neck 4 and it acts as guide of closing capsule 2 for the correct centring of the entire closing system.

[0041] From the preceding description the setting up of the container according to the invention, and the operation thereof appears easily understandable.

[0042] From the now completed description of the individual components it appears evident that the mounting is particularly simple. Once spring 13 has been inserted so that it may rest below on the upper surface of collar 8, the head 9 of stem 3 is brought into engagement with the cylindrical appendix 2f of capsule 2, so as to maintain the axis of stem 3 perfectly centred. Subsequently, rotating ring 10 is inserted into coupling ring 12, so that the annular abutment recess 12a may support it, and subsequently coupling ring 12 is brought into engagement with capsule body 2b, simply engaging by pushing notches 12a into seat 2e. At this point, cylindrical hood 2a is brought to cover capsule body 2b.

[0043] Equally, tank 1 is first provided with scraper 13, in correspondence of the top surface of neck 4, and subsequently with plastic gasket 14 provided on the top of the container in correspondence of the protective collar of the closing member.

[0044] The operation of the device thus created appears particularly simple.

[0045] Once capsule 2 has been brought into contact with tank 1, pegs 11 are housed in rail 6: the pressure of the finger on capsule 2 pushes the pegs 11 along rail 6 until they reach the bottom surface of base crown 5; by releasing the capsule, it will be brought by spring 13 to raise back into the home position, bringing pegs 11 to find housing in the recess 7a of brackets 7.

[0046] Similarly, when the user wants to apply the product, he/she must only push onto capsule 2, so that pegs 11 are displaced from the equilibrium position and are induced, due to the geometries of crown 5 and of brackets 7, to raise back along rail 6.

[0047] From the preceding description it appears evident that the set objects have thus been obtained, that is, a quick-opening container, wherein greater simplicity during assembling, improved stability of the pegs when they are engaged with the guiding and retaining bodies, a longer and consequently easier opening movement, are detectable.

[0048] Moreover, it was possible to detect that the solution just described has some unexpected advantages, which, however, are not unworthy of being remembered. In particular, the simplification of the displacement and engagement system has made the rotating ring free from any other constraint, entrusting centring and guiding of the rod to the rod itself and to the capsule. This implies greater precision during device operation and greater mounting simplicity.

[0049] Moreover, the plastic material gasket provided at the top of the container in correspondence of the protective collar of the closing member takes up the double function of aesthetic improvement and of more precise guiding.

[0050] It is also evident that non-substantial changes can be made to the solution described above, accomplishing alternative embodiments, without departing from the scope of protection of the patent, which is defined by the attached claims.

[0051] In particular, as can be observed from FIGS. 10a and 10b, it is possible to provide that tank 1 has a smaller diameter than that of capsule 2, and therefore the function of sleeve C is accomplished by the very capsule 2, and/or that gasket 15 takes up such proportions as to be able to have itself an ornamental function.
