(21) The cap 14 and the base 16 are separably mountable to each other along a mounting axis M to form the cosmetic container 1, as shown in FIGS. 1 and 2.

(22) As shown in particular in FIGS. 1-6, and 13, the cap 14 is of curvilinear shape.

(23) As shown in particular in FIGS. 1-3, 5-6, and 14-16, the cosmetic container 1 comprises a central cap 140 including an upper inner shell 149. The central cap 140 is separably mountable with the cap 14 along the mounting axis M.

(24) The central cap 140 is of curvilinear shape.

(25) The upper inner shell 149 is provided between the cap 14 and the base 16, and the upper inner shell 149 has a complementary shape with respect to an outer surface of the lip balm 2 in solidified phase. The outer surface of the balm 2 is of curvilinear shape adapted to apply the balm 2 on the lips.

(26) Advantageously, the upper inner shell 149 is mounted to the base 16 during the filling step, thus facilitating the mounting operations and simplifying the cosmetic container 1. The upper inner shell 149 and the base 16 contain the balm 2 in a heated semi-fluid phase during the filling step.

(27) The upper inner shell 149 is of curvilinear shape.

(28) Advantageously, the central cap 140 allows the outer cap 14 to have any shape in a simpler manner, since the external shape of the central cap 140 may follow the shape of the upper inner shell 149, while the outer cap 14 may have any shape.

(29) As shown in particular in FIG. 13, the cap 14 comprises an inner threaded portion 15.

(30) As shown in particular in FIGS. 1, 7, 11 and 12, the base 16 comprises an outer threaded portion 17. The inner threaded portion 15 of the cap 14 screws on the outer threaded portion 17 of the base 16.

(31) As shown in particular in FIGS. 1, 15 and 16, the central cap 140 includes interlocking elements 141, which interlock with interlocking elements 191 of an inner surface of the cap 14. As shown, in particular in FIG. 13, the interlocking elements 191 of the inner surface of the cap 14 have a complementary shape with respect to the interlocking elements 141 of the central cap 140.

(32) Advantageously, when unscrewing the cap 14 from the base 16 to open the cosmetic container 1 to apply the lip balm 2, the central cap 140 is mounted on the cap 14 and, therefore, it is sufficient to only unscrew the cap 14 to open the cosmetic container 1 and apply the balm 2 on the lips.

(33) As shown in particular in FIGS. 5-12, the base 16 comprises a support frame 30 to support the lip balm 2 in solidified phase.

(34) The support frame 30 is advantageously in one piece with the base 16 to simplify the mounting of the cosmetic container 1, and making the mounting operations of the cosmetic container 1 quicker and safer.

(35) The support frame 30 of the base 16 supports the lip balm 2 in solidified phase.

(36) The base 16 comprises a lower inner shell 3.

(37) The lower inner shell 3 comprises a border 181 in contact with an outer wall 161 of the base 16 and the inner central portion 180, which is the bottom of the lower inner shell 3. The border 181 of the lower inner shell 3 is arranged at a higher level with respect to the inner central portion 180 of the lower inner shell 3. The level is measured along the mounting axis M.

(38) The lower inner shell 3 is of concave shape to even further simplify the cosmetic container 1.

(39) At the bottom of the base 16, a through opening 23 is provided, and is adapted to allow the passage of balm 2 in heated semi-fluid phase during a filling step of the balm 2 in heated semi-fluid phase into the cosmetic container 1.

(40) An inner central portion 180 of the lower inner shell 3 is the inner bottom of the base 16 and opens in the through opening 23. The through opening 23 opens the inside of the cosmetic container 1 outwards.

(41) As shown in particular in FIGS. 4-12, the support frame 30 of the base 16 comprises a central hollow hub 36 extending along the mounting axis M of the inner central portion 180 of the lower inner shell 3 of the base 16 toward the upper inner shell 149.

(42) The central hollow hub 36 comprises an inner cavity 360 opening at the bottom in the through opening 23. The central hollow hub 36 comprises an outer surface 380 facing toward the lower inner shell 3 of the base 16.

(43) The support frame 30 of the base 16 comprises a multiplicity of radial walls 34 partitioning the inside of the lower inner shell 3 into sectors of space 18 of the lower inner shell 3. Each radial wall 34 of the multiplicity of radial walls 34 extends in two directions. Each radial wall 34 extends radially from the outer surface 380 of the central hollow hub 36 toward the outer wall 161 of the base 16. Each radial wall 34 extends along the mounting axis M from the lower inner shell 3 of the base 16 toward the upper inner shell 149.

(44) The central hollow hub 36 comprises a multiplicity of radial through slits 500 which allow the balm 2 in heated semi-fluid phase to flow in a controlled manner without damaging the cosmetic container 1 and preventing the balm 2 from being contaminated or becoming cloudy. Each radial through slit 500 of the multiplicity of radial through slits 500 is arranged between two adjacent radial walls 34 of the multiplicity of radial walls 34. Each radial through slit 500 is adapted to allow the passage of the balm 2 in heated semi-fluid phase during the filling step between the inner cavity 360 of the central hollow hub 36 and one of the sectors of space 18 of the lower inner shell 3 of the base 16.

(45) Advantageously, at least one radial through slit 500 is arranged between two adjacent radial walls 34 of the multiplicity of radial walls 34 so that each sector of space 18 of the lower inner shell 3 of the base 16 is supplied with balm 2 in heated semi-fluid phase during the filling step by the at least one radial through slit 500.

(46) Advantageously, each radial through slit 500 is arranged on a lower portion 363 of the central hollow hub 36 to even better control the flow of balm 2 in heated semi-fluid phase inside the cosmetic container 1.

(47) Each radial wall 34 of the multiplicity of radial walls 34 comprises an upper portion 349 comprising at least one upper overflow through slit 340. Each upper overflow through slit 340 is adapted to allow the passage of the balm 2 in heated semi-fluid phase during the filling step between at least two of the sectors of space 18 of the lower inner shell 3 of the base 16.

(48) At least one upper overflow through slit 340 is arranged at the upper portion 349 of the radial wall 34 in proximity of the central hollow hub 36. The at least one upper overflow through slit 340 is adapted to allow the passage of the balm 2 in heated semi-fluid phase during the filling step between the inner cavity 360 of the central hollow hub 36 and at least two of the sectors of space 18 of the lower inner shell 3 of the base 16. As shown, in particular in FIGS. 7, 9, and 12, a multiplicity of upper overflow through slits 340 are arranged on the upper portion 349 of each radial wall 34 in proximity of the central hollow hub 36 so as to favor the passage of the balm 2 in heated semi-fluid phase between the sectors of space 18 and the inner cavity 360 of the central hollow hub 36.

(49) As shown in particular in FIGS. 1, 5, 6, 12, 17 and 18, a lower plug 160 closes, from the outside, the through opening 23 of the base 16.

(50) With regard to the filling step of the balm 2 in heated semi-fluid phase into the cosmetic container 1, the cosmetic container 1 is flipped over, the upper inner shell 149 is mounted on the base 16 and the through opening 23 faces upwards to facilitate the introduction of the balm 2 in heated semi-fluid phase. The balm 2 in heated semi-fluid phase is inserted inside the through opening 23 of the base and advantageously flows in a controlled and constant manner inside the inner cavity 360 of the central hollow hub 36 without becoming cloudy, without being contaminated and without damaging the cosmetic container 1. The balm 2 in heated semi-fluid phase flows in a controlled and constant manner from the inner cavity 360 of the central hollow hub 36 to the sectors of space 18 of the lower inner shell 3 by means of the radial through slits 500 filling them gradually, in a controlled manner. The balm 2 in heated semi-fluid phase flows inside the base 16 in the direction of the upper inner shell 149 in a controlled manner. Upper overflow through slits 340 of the radial walls 34 allow the passage of the balm 2 in heated semi-fluid phase between the sectors of space 18 and the inner cavity 360 even better distributing the balm 2 inside of the cosmetic container 1 and allowing it to flow in a controlled manner. The upper inner shell 149 is filled with the balm 2 in heated semi-fluid phase, up to an upper portion of the support frame 30 of the base 16. The lower plug 160 closes the through opening 23 of the base 16.

(51) Advantageously, the base 16 is already mounted, facilitating the mounting operations of the cosmetic container 1, thus reducing the mounting operations. It is only necessary to close the through opening 23 of the base 16 with the lower plug 160 once the filling step has ended.

(52) Advantageously, the balm 2 in heated semi-fluid phase flows in the cosmetic container 1 in a controlled manner without damaging it, and the balm 2 is not contaminated nor does it become cloudy.

(53) The shape of the base 16, which includes the central hollow hub 36, the multiplicity of radial through slits 500, the radial walls 34 partitioning the lower inner shell 3 into sectors of space 18 advantageously allow the balm 2 in heated semi-fluid phase to flow in a controlled manner and with a constant flow toward the upper inner shell 149, without damaging the cosmetic container 1, without making the balm 2 cloudy and without contaminating the balm 2.

(54) The upper overflow through slits 349 allow easier identification of when the cosmetic container 1 is filled up with the balm 2 in heated semi-fluid phase, advantageously allowing better leveling of the balm 2 without lumps or protrusions, so that once the balm 2 is in solidified phase, it can be better and more securely supported by the supporting frame 30 of the base 16.

(55) Once the balm 2 is in solidified phase, the support frame 30 supports it.

(56) As for the application of the balm 2 in solidified phase to the lips of a person, it is sufficient to remove the cap 14 on which the central cap 140 is mounted, by uncovering the balm 2 with the cosmetic container 1 open.

(57) Alternatively, the cap 14 can have an outer shape of any kind. The upper inner shell 149 has a complementary shape with respect to an outer surface of the lip balm 2 in solidified phase.

(58) Alternatively, the central cap 140 can have an outer shape of any kind. The upper inner shell 149 has a complementary shape with respect to an outer surface of the lip balm 2 in solidified phase.

(59) Alternatively, the central cap 140 is not provided. In the alternative, the cap 14 comprises the upper inner shell 19, which has a complementary shape to an outer surface of the lip balm 2 in solidified phase.

(60) Alternatively, the central cap 140 is separably mountable with the base 16 along the mounting axis M. The cap 14 is, in turn, separably mountable to the base 16, but not with the central cap 140. In the alternative, the central cap 140 comprises the upper inner shell 149. In the alternative, the central cap 140 comprises an inner threaded portion 15. The base 16 comprises the outer threaded portion 17. The inner threaded portion 15 of the central cap 140 is adapted to be screwed onto the outer threaded portion 17 of the base 16.

(61) Alternatively, the lower inner shell 3 of the base 16 is of a shape comprised in a list comprising a lower inner shell 3 of curvilinear shape, of convex shape, star-shaped, cone-shaped with surfaces protruding toward the central hollow hub 36.

(62) Alternatively, the upper inner shell 19, 149 has a complementary shape with respect to an outer surface of the lip balm 2 in solidified phase, which may be of any shape adapted to allow the application of the balm 2 on the lips.

(63) Alternatively, more than one radial through slit 500 is arranged between two adjacent radial walls 34 of the multiplicity of radial walls 34 so that each sector of space 18 of the lower inner shell 3 of the base 16 is supplied with balm 2 in heated semi-fluid phase during the filling step by the at least one radial through slit 500.

(64) Alternatively, it is possible to provide that at least one radial through slit 500 is arranged on an upper portion of the central hollow hub 36 or still on a portion different from the lower portion 363 of the central hollow hub 36. It is possible to provide that the radial through slits 500 are arranged along the entire central hollow hub 36.
