Definitions

  • the present invention refers to a container for solidified products, such as deodorants, lipsticks, stationary glue and like.
  • Containers having a stick holder slider are known, said slider being driven along the inner longitudinal axis by an outer tubular body operated by a situated below knob. axially coupled with, but freely rotating with respect to, the bottom of said outer body.
  • the above mentioned containers comprise at least 2 bodies for the closure system and at least 4 bodies for the container mechanism, all employing a stick holder screwing engaged with a screwed rod.
  • all the containers have at least a body with a detachable body
  • the mechanism according to the present invention allows to remarkably cost reduction since provides, in function of the kind of product filling from the above or from the bottom, respectively one or two body for the closure system and only two bodies, instead of at least four, for the container mechanism.
  • the mechanism of the container according to the present invention is substantially comprised of:
  • the axial helix rotates following a rotation of the knob, said helix being engaged with the relevant complementary helix axial cavity coined within the stick, said stick, being prevented to rotate by the not cylindrical section of the inner wall of the outer body, axially slides along said wall.
  • the container according to the present invention shown as embodiment suitable for not cylindrical stick shaped products, such as oval shape and like, comprises an outer tubular body 1, a bottom surface 2 and an open top edged end 3.
  • Said outer tubular body 1 provides close to the top a peripheral shoulder 4, upon which the lower end of the cover 5 abuts, dividing the outer surface into two parts, the superior one 6 of which having a lower thickness with respect to the lower one 7.
  • a cylindrical wall portion raises axially toward the inside of the container, said surface 10 being provided with a flat top surface 11, from the inner diameter of which a second short cylindrical wall axially inside raises, said second wall having a lower diameter, on the upper end of which an annular edge projecting toward the centre with an opening 13 is obtained, suitable to determine first snap engagement means.
  • the three above described bodies are assembled in such a way that the cover 5 pushes by a step of the inner surface 14 on the peripheral outward projecting edge 8 of the cap 9 closing by a tight seal with the liquid product, the edge 3 of the upper end of the outer tubular body 1.
  • a rotation body 16 is telescopically inserted in an upset position.
  • Said rotation body 16 comprises a rotation knob 17 and an axial helix 18.
  • the rotation knob 17 is made up of a tubular body provided with a flat top surface, from the inner diameter of which a second short peripheral cylindrical wall raises, having a lower diameter and provided with closed top surface 21 having projections 22 along the annular edge faced outward, in order to determine the second respective snap fitting means.
  • annular seal "O-ring” 24 elastically bears on the inner surface of the second short cylindrical wall 12 to make by its rotational movement an annular hermetic seal against volatile substances eventually present in the contained product.
  • an axial helix raises, having constant radius and pitch, axially projecting within the container, substantially all along its length, close to the level of its upper end, when said knob is completely inserted within the bottom of the outer tubular body.
  • the axial helix 18 preferably has an outer cylindrical profile just a little lower than the diameter of the closed top surface 21, an inner cylindrical profile with a diameter reduced as more as it is possible and a very long pitch so as to determine a fast screwing.
  • the axial helix 18 could be more or less retractable along its length.
  • the stick takes the shape shown in figures 1 and 3 with the following limitations:
  • an important feature of the present invention is that the axial helix shaped cavity 26, complementary to the axial helix 1, obtained within the stick mass, allows that said stick is a body making part of the roto-translation mechanical system.
  • a rotation of the axial helix 18 is obtained, i.e. the first rotation mechanical means, which by the thrusting action along its helical generated inclined plane along the relevant inclined plane of the axial helix shaped cavity 26 of the stick, i.e. the second roto-translation means, determines an axial movement downward or upward, of the stick, depending on the rotation direction, being the latter prevented to rotate by its not circular section:
  • the stick is supported by a stick holder; lacking this body in the solution according to the present invention, the support of the stick is due to the axial helix shaped cavity 26 resting on the surface of the axial helix 18.
  • an empty zone 27 has been provided under the solidification level 15', so as to allow a stroke without damaging in the bottom of the stick.
  • stops so that the bottom of the stick is prevented to further descend under a level established beforehand, said stops comprising a series of thin axial ribs 28 provided on the lower portion of the inner wall 22 of the outer tubular body 1 .
  • the thickness of these ribs determines a scraping action of the outer surface of the bottom of the stick, so as to induce the user to avoid to further move the stick downward beyond the pre-established lower stop, to avoid that the axial helix 18 forced to rotate cuts the axial helix shaped cavity 26 of the stick, being this surface a means determining the roto-translation motion.
  • the rotation body 16 comprising the rotation knob 17 ad the axial helix 18, is assembled by a snap coupling within the container before the product filling step.
  • the liquefied product is poured from the above within the container up to reaching the upper level 29 under the edge 3 and left cooling until the complete solidification of the stick product.
  • the stick takes the shape shown in figures 6 and 7, with the following limitations:
  • the solidification surface 30 of the stick is complementary to:
  • the stick takes the shape of figure 6.
  • the stick after its solidification is raised, acting on the rotation knob 17, at a certain level so as to restore, as in case of figure 1 and already described, an empty zone 27, to allow a predetermined stroke without bottom damaging.
  • the upper end of the stick can thus remain with its solidification surface of the upper level 29, or, in case it is enough raised so that said upper level 29 is above the edge 3, it can be tapered by a spatula to have the upper flat end 33 of the stick on the same plane of the edge 3 of the container, as shown in figure 7.
  • the container according to the present invention is shown according to an altemative embodiment suitable for lip-stick, stationery glues and like cylindrical containers.
  • the outer profile of the axial helix 18 can also generally speaking extend with any diameter up to the inner wall 125. Therefore, even if it is not shown in the drawings, the inner cylindrical profile can be, generally speaking and if it is preferred, with a bigger diameter.
  • the inner tubular wall 125 of the outer tubular body 101 has a circular cross-section and is provided with at least a guide axial rib 34 co-acting with a relevant guide axial groove 35 of the stick in order to prevent the rotation of said stick during the rotation movement of the axial helix 18.
  • the rotation knob 17 is under the bottom surface 102, lacking the container portion corresponding to the cylindrical wall portion 10 of the container shown in the preceding figures 1 - 7.
  • the filling according to an altemative variation is carried out with two different products, in different steps, said products once solidified realising a stick having two different consistencies along its height, divided by a separation line 36 between the products, in correspondence of said line the stick, faced toward the bottom has a short height 37, sufficient to define a slider function, is much more consistency with respect to the product faced toward the end, to better withstand to fracture, when it pushes against the bottom, and to the pressure directed toward the bottom, when the product is almost completely finished, see for example figure 5.
  • the short stick 37 being it also possible that is different with respect to the product to be used, is provided with a tubular outer wall having the guide axial groove 135 co-acting with the relevant guide axial rib 34 and an axial helix shaped central cavity 126.
  • the container has the upper end with a sloped edge 203, lying for example along a 30° oblique plane and provided with a corresponding cap 109 with relevant bottom plane 38 sloped of 30°, for the conformation of the upper end of the stick during the solidification process, with a filling from the bottom in an upset position.
  • the container of the present invention shown with an oval cross-section, is illustrated according to an alternative embodiment suitable for viscous fluid products, such as gel, cream, paste and like.
  • the outer tubular body 201 has the upper end provided with a closed surface 39 having at least a delivery opening, preferably with many delivery openings, from which the fluid viscous product is delivered following to the control of the rotation knob 17.
  • a cap 209 inserted within the cover 5, closes by its bottom surface 41, complementary with respect to the closed surface 39, the delivery openings 40.
  • Said outer tubular body 201 has the lower end opened provided, at a certain height of the inner wall 25, with a little annular shoulder 42 determining a reduced thickness wall 43, where it is obtained on the inner wall at least a perimetrical groove 44, in order to determine a first engagement snap perimetrical means.
  • Inner part of the container is filled with a first viscous fluid product.
  • the liquefied product is solidified with a short stick shape 37 sufficient to determine a stick slider supporting the viscous fluid product to be used.
  • the axial helix 18 is provided with an axial rod 49 integral with its inner cylindrical profile.
  • the outer tubular body 101 provides on the outer surface a peripheral shoulder 104, upon which the lower end of the cover 205 abuts, dividing said outer surface into two parts, the upper one 106 having a reduced thickness and being provided with a thread 50 to be screwed with the cover 205.
  • a relevant peripheral body 51 having an hermetic seal with respect to the liquid product abuts, said body projecting downward from a cap 309, within the cover 205, conforming by its inner surface acting like a mold the upper surface of the stick during the solidification process.
  • the outer tubular body 101 provides a bottom part 102 centrally delimited by a short coaxial cylindrical wall 12, on the upper end of which an annular edge centrally projecting and with an opening 13 is obtained, in order to determine a first snap means.
  • a rotation body 116 is telescopically introduced, comprising: a rotation knob 117, provided with a top surface 119, a short cylindrical wall 120, a closed top surface 121, with projections 22 faced outward, second relevant snap engagement means, from which an axial helix 18 provided with an axial rod 49 raises, said helix being integral with its inner cylindrical profile.
  • the thickness of the lower outer surface 7 of the outer tubular body 101 is uniform up to the annular notch 52, from which two different thin tubular walls 53 and 54, and therefore elastic, continue separated each other following the respective profiles of the outer wall and of the inner wall, the latter being coupled to the bottom surface 102.
  • the lower end of the outer tubular thin wall 53 elastically frictions, with a hermetic sealing, with the annular comer 55 inside faced on the inclined annular edge 56 placed on the periphery of the flat top surface 119 of the rotation knob 117, in order to reduce the use of an added body, such as the "O-ring" annular seal 24.
  • an empty zone 27 and some wedged thin sloped axial ribs 57 have been provided on the bottom of the inner portion 125, comprising some narrowing of the inner tubular thin wall 54 to determine a scraping action of the bottom of the stick in order to induce the user to avoid to operate the same beyond the lower pre-established stop level.
  • the cap 309 powerfully controlled by the screwing of the cover 205, with the thread of the stick top surface, can freely slide, with a calibrated friction resistance, sliding within the inner tubular wall of said cover 205, in such a way to avoid the fracture of the axial helix shaped cavity of the stick, being prevented to go down.
  • the outer tubular body 101 provides a peripheral shoulder 104, upon which the lower end 58 of the cap 409 within the cover 105 abuts, dividing the outer surface into two parts, the upper one 106 having a reduced thickness.
  • the thickness of the outer tubular body 101 divides into two different tubular thin walls 153 and 154, separated by a tubular cavity 152, continuing separated each other following the relevant profiles of the outer wall and of the inner wall.
  • the thin tubular wall 154 joins with the bottom surface 102, the latter being provided with outer annular edge 59 on the outer periphery and inner annular edge 60 on the inner periphery, both projecting downward.
  • a spiral labyrinth shown with 3 - 4 tums, is obtained, comprising a spiral groove 61, with inside stop 62, outer stop 63, defined by spiral edges 64 projecting downward, wherein an upper tooth 65 obtained on the upper surface of a thin ring body 66, between said spiral labyrinth and the flat top surface 119 of the rotation knob 117.
  • the outer tubular body 101 can freely rotate only for 3 - 4 turns in either direction with respect to the rotation body 116 since the upper tooth 65 moves from the inner stop 62, in correspondence of the inner annular body 60, to the outer stop 63, in correspondence of the outer annular body, and vice versa, covering 3 - 4 tums along the spiral groove 61, while the relevant lower tooth 67 moves along the radial slit guide 68, between the lower stop 69 and the upper stop 70.
  • the upper tooth 65 can be realised, according to an alternative embodiment not shown in the drawings, on a mono-piece molded elastic arcuate strip realised on the crown top wall 119, so as to replace the thin ring separated body 66.
  • a cylindrical wall 220 raises, on the outer surface of which a thread 71 is realised, having narrow pitches substantially with an equal number of those of the cylindrical axial helix 18, screwed with a thin ring body 72, provided on the outer periphery of a series of axial grooves 73, like the millerighe kind, engaged with at least a rib 74 obtained within the short cylindrical wall 112, raising from the periphery of the bottom surface 102.
  • the outer tubular body 101 is free to rotate, as shown in figure 17, only for 3 - 4 turns in either direction with respect to the rotation body 116 since the threaded thin ring body 72 can only slide from the lower stop, when it is in correspondence of the flat top surface 119, to the upper stop, when it is in correspondence of the second transversal crown surface 75, the outer periphery of which is joined with the short cylindrical wall 112, raising from the periphery of the bottom surface 102.
