DESCRIPTION OF EMBODIMENTS

[0138] This description of several embodiments of the invention is made with reference to the drawings of the figures. It is specified that the drawings are not all to the same scale for reasons of readability. The words used must be construed and understood in the light of the field of the invention and the background, as presented above. Generally speaking, the embodiments are non-limitative.

[0139] The case of the invention is a mass market trivial personal daily use compact plastic case intended to be discarded after use of the content, with a side opening/closing hinge for a product forming a solid mass suitable for removal by means of a pick-up utensil or manually, such as cosmetic product, e.g., face powder, makeup, eye shadow, blush, concealer, lip gloss, lipstick, eyeliner. The case is destinated for a rather limited number of uses (but quite more than for a simple sampling or testing). The case is not specially designed to be refillable, but it can be according to one embodiment. The product does not contain any significant volatile component whose evaporation or leakage it would be essential that the case prevents, and so, the case is not specially designed to comprise specific sealing means for this purpose. Other applications are possible for pharmaceutical products, skincare products, coating products, treatment products, decorative products, and more generally products having as regards packaging, removal, and use, similar or equivalent features and requirements.

[0140] The case may be without product within (empty state), that is an empty case 1 or, by ellipse, case 1 (FIG. 14, 15) or in loaded state with product within (FIG. 16, 17, 18), that is a loaded case LD. The case 1 comprises an interior storage space 2 in which is disposedin the loaded statea mass of the product, called content C of product (or by ellipse content C). The loaded case LD is the assembly comprising the case 1 and the content C. The case 1 comprises a side opening/closing hinge 3 or, by ellipse, hinge 3, for the relative pivotal movement of its components. The case 1, LC, may be in a closed configuration in which the content storage space 2 is closed (FIGS. 1 to 4), or in an opened configuration of use, in which access to the storage space 2 and to the content C is possible (FIGS. 14 to 16). The closed configuration, without any access to the storage space 2, is that where the case LD is presented to sale, sold (possibly with protective, commercial, or informational support), owned by the user, stored when not in use. The opened configuration of use is that of normal use where the user can remove a quantity of the product from the free upper surface 4 of the content C. The case 1 may be in assembled situation, in which its components are assembled together (FIG. 1, 14, 15), and in unassembled situation, in which such components are not yet assembled together (FIG. 5, 23). With the method of manufacturing such a component of the case 1, the latter is produced in a so-called manufacturing conformation (possibly with an intermediate manufacturing conformation). The case 1, LD, comprises a lower transverse case support plane allowing to be at rest on a shelf or work top.

[0141] According to the embodiments, the case 1 is generally cylindrical, typically with a circular or almost circular guideline (as depicted on the figures), or polyhedral, typically right parallelepiped or with a curved outline or truncated angles. The case 1, LD, in closed configuration, mainly extends in length and width in directions transverse to a median main axis A. It extends in height in the direction of the main axis A. Typically, the main axis A is vertical when the case 1, LD is at rest on a shelf or work top. Axial refers to that is disposed on, or parallel to, the main axis A and transverse refers to that is disposed perpendicular or orthogonally to the main axis A. Radial refers to that which extends in transverse direction passing through the main axis A. Perimeter refers to what goes around the main axis A. Internal and external qualify respectively and relatively to what is closest or facing the main axis A, and what is farthest from or facing away from the main axis A. Exterior qualifies, what is totally or at least substantially or normally outside or visible or touchable in the closed configuration. Interior qualifies the contrary of exterior. Lateral qualifies what is on the side of the main axis A. It is with the reference of the main axis A being vertical that should be understood the words low, up, top, below, and other words qualifying a direction, an orientation, or a relative position. The arrangement of the hinge 3 is specially designed to provide a pivot axis space which extends in a lateral transverse direction B (FIG. 5, 6). The case 1, LD, may be oriented differently than it is with its main axis A vertical and consequently the words low, up, top, below, and other words qualifying a direction, an orientation, or a relative position are not limiting the scope of the invention. The case 1, LD is compact and flat, i.e., in closed configuration, its overall length, its overall width, and its overall height have an order of magnitude of centimeter (or a weight of content product between around 1 g to 15 g) while the ratio overall height/overall length or overall width is comprised between 1/7 to 1/3. As a purely illustrative and non-limiting example, the case 1, LD may have an overall diameter of around 4.6 cm and an overall height of around 1 cm.

[0142] The case LD in loaded state (FIG. 18 in closed configuration and FIG. 16, 17 in opened configuration) comprises the case 1 and the content C. The case 1 comprises, more particularly consists of, two separate components 5 and 6, with the advantage of the minimum number of components. The component 5 comprisesmore particularly according to one embodiment consists of the combination of a bottom 7a cover 8 and the hinge 3 (reason for which the component 5 is named either a bottom plus cover plus hinge component or by ellipse a bottom+cover+hinge component). The component 6 is a closure insert (or by ellipse insert 6). Like the case 1, each component 5, 6, has its own main axis A.

[0143] We refer to FIG. 8 which represents the bottom+cover+hinge component 5 in its intermediate manufacturing conformation in which it is fully opened flat at 180. The component 5 is one single monobloc plastic component integrally molded in the fully opened flat configuration extending along a transverse radial axis E, in which the bottom 7 and the cover 8 extend next to each other, separated by the hinge 3. The manufacture of the component 5 in its intermediate manufacturing conformation, is followed by a relative pivoting closing movement of the bottom 7 and the cover 8 (arrow CA of FIG. 22) to bring the component 5 into the closed configuration (FIG. 19).

[0144] The material of the component 5 is selected on one hand as being a suitable plastic material for the manufacture, use, and other requirements here required for component 5, which can be injection molded, to be chemically compatible with the product of the content, be recyclable, be hard enough to withstand touch, impact, and wear. The material of the component 5 is selected on the other hand so that, with a thickness such as the thickness of the walls of the bottom 7 or the cover 8, it forms something which is sufficiently rigid as a whole, and with a thickness such as the thickness of the hinge 3, it forms something which is sufficiently deformable as a whole. The term sufficiently rigid should be understood to mean to be able to withstand mechanical pressure or deformation stresses such as those that a user could apply during routine use. The term sufficiently deformable, should be understood to mean to be able to be deformed so as to ensure a pivoting function when subjected to forces such as those that a user could apply during normal daily use. The term something should be understood to mean a physical body, having a certain thickness, made up of the selected plastic material. The walls 10, 16 and 17 of the bottom 7 and the cover 8 made with the material so described have thicknesses chosen so that the bottom 7 and the cover 8 are sufficiently rigid as a whole, while the hinge 3 has a thickness chosen to be sufficiently deformable as a whole, and capable of easily pivoting with reference to the pivot axis space. By bottom 7 and cover 8 sufficiently rigid as a whole, it should be understood that the bottom 7 and the cover 8 resist mechanical stresses of pressure or deformation such as those which a user could apply to them during a normal routine use such as handling. By hinge 3 sufficiently deformable as a whole, it should be understood that the hinge 3 is deformable in such a way that it fully fulfills its function of pivot when it is subjected to forces such as those that a user could apply to it during normal daily use such as opening or closing cover 8 from the bottom 7. Typically, the material of component 5 is a thermoplastic polymer having chains of molecules which can be oriented, as necessary. According to one embodiment, the material of component 5 is polyolefin or a polyolefin composition. In a particular embodiment, the material of component 5 is a polypropylene composition. In a particular embodiment, the material of component 5 is polypropylene. The material of component 5 can also be an equivalent, providing in the application considered for the production of component 5, analogous results, in that the bottom 7 and the cover 8 are sufficiently rigid as a whole and that the hinge 3 is sufficiently deformable as a whole.

[0145] The bottom 7 has an annular shape and forms a hollow 9 with two openings 12, 13, on either side in the direction of the main axis A. The bottom 7 comprises a lateral peripheral bottom wall 10 having an upper portion 10a, an internal peripheral face 10b, and a lower edge 11. The bottom 7 comprises the top transversal bottom opening 12. The lower transversal bottom opening 13 is limited by a lower bottom opening edge which is the lower edge 11. The bottom 7 has no lower transversal wall in the sense that the lower bottom opening 13 is so as large as possible, since it extends to the internal peripheral face 10b. The lower edge 11 defines the lower support plan of the case 1, LC. The bottom 7 also comprises a means for fixing 15 the insert 6. The hollow 9 defines a lateral envelope in which is located the interior storage space 2. So, the function of the hollow 9 is to house the content C. The function of the top transversal bottom opening 12 is to allow access to the free upper surface of the content C andaccording one possible embodiment, to allow the filling with the content C. The function of the lower bottom opening 13 is to allow the introduction and association of the insert 6 into and with the bottom 7 andaccording one other possible embodiment, to allow the filling with the content C. The cover 8 comprises a transversal cover wall 16 and below a lateral peripheral cover wall 17 limiting a lower transversal cover opening 18. The hinge 3, associated integral between the bottom 7 and the cover 8, is chosen to be a film hinge, in particular a butterfly film hinge. According to different embodiments, the transversal cover wall 16 may be planar or may not be planar, for example more or less convex, protruding or recessed, or with other shapes.

[0146] The component 5 also comprises, integrally molded, a means to maintain 19. The means to maintain 19 maintains the bottom 7 and the cover 8 in the closed configuration in the absence of an appropriate opening bias. The means to maintain 19 is reversible and associated with the bottom 7 and the cover 8.

[0147] As represented on FIG. 20, 21, according to one embodiment, the bottom+cover+hinge component 5 is bi-injected molded with a first material PP1 for the bottom 7 and a second material PP2 for the cover 8. According to one embodiment, the hinge 3 is injected molded with the second material PP2, as is injected molded the cover 8. According to one embodiment, the first material PP1 is opaque (or sufficiently opaque) and hides the technical means of the insert 6. And the second material PP2 is transparent or translucent (or sufficiently transparent or translucent), having a certain transparency or translucency allowing to see the free upper surface of the content C, in particular its color, through the cover 8 in closed configuration. However, other configurations are possible.

[0148] We refer to FIGS. 1, 6, to 10 concerning the bottom 7. The bottom 7 comprises at its top end a bottom top rim 20 (or by ellipse top rim or rim), arranged transversely and directed towards the main axis A, extending from the upper portion 10a of the peripheral bottom wall 10, with an intermediate recessed set back portion of rim 20a. The set back portion of rim 20a comprises two adjacent wedge-shaped portions, namely a transversal portion 52a which is disposed transversely adjoining the upper portion 10a of the peripheral bottom wall 10 and an axial portion 52b which is disposed axially adjoining the external edge of the rim 20. The transversal portion 52a has an annular transversal lower face 53a and the axial portion 52b has a peripheral internal axial face 53b. The protruding angle formed by the transversal portion 52a and the axial portion 52b is directed towards the main axis A. The rim 20 itself has an annular rim transversal upper face 23a and an annular essentially rim transversal lower face 23b. The annular upper face 23a is suitable, for the loaded case LD, to form an entourage surrounding the content C. When the loaded case LD is in the opened configuration, the annular upper face 23a is visible. According to an embodiment shown on FIGS. 16 to 19, it is provided, at the location of the hinge 3, that there may not be the upper side of the axial part 52b of the recessed part of the rim 20a and the outer side of the rim 20, these parts being limited by a truncated face 54a inclined on the main axis A, from the externa side to the internal side, and from bottom to top, so as to leave an empty space 54b facilitating the pivoting movement of the hinge 3.

[0149] The rim 20 has an annular outline, with an external diameter which is D (FIG. 18) The rim 20 has a limited annular radial dimension, in particular a radial dimension sufficient, or more particularly just sufficient, to allow the internal peripheral wall 34 of the insert 6 to be located below in plumb line. Opposite to the wall 10, the rim 20 has an internal edge 21 which defines the peripheral edge of the top bottom opening 12, the diameter of which is d (FIG. 18). According to one possible embodiment the internal edge 21 has a rounded shape (FIG. 6). According to a first possible embodiment (FIG. 6), the internal edge 21 includes a short axial falling portion directed towards the lower bottom opening 13 with a free transversal face 21a. With this first embodiment, it is possible, according to one particular embodiment, that the external peripheral lateral face of the falling portion has a position that is slightly inclined on the main axis A upwards and the external side. With this arrangement, the external peripheral face of the falling portion of the rim 20, and so the rim 20 itself, may fulfill a centering function of the insert 6 relatively to the main axis A, because the external peripheral face of the falling portion of the rim 20 may guide properly the top internal edge 24a of the insert 6 during its installation by pressing upwardly into the bottom 7. According to a second possible embodiment, the internal edge 21 has no such above described falling portion. According to the first embodiment above described the distance in the direction of the main axis A between the two planes of the rim transversal lower face 23b and of the free transversal face 21a is small, such as less around 1 mm, e.g., around 0.5 mm. According to the second embodiment above described the rim transversal lower face 23b and of the free transversal face 21a are in the same plane. The rim 20 fulfills at least the function of providing a space which is closed from above and in which the upper part of the insert 6 (that is the part of the internal peripheral wall 34 adjacent to a top first surrounding 24) can be placed, and further to conceal such upper part of the insert 6 from view, in the embodiment in which the rim 20 is opaque or sufficiently opaque.

[0150] The top first surrounding 24 of the insert 6 is facing the rim transversal lower face 23b. According to another first possible embodiment (FIG. 6), a top first surrounding 24 of the insert 6 is not in contact with the rim transversal lower face 23b but located close. It cannot be excluded in another second possible embodiment, that the top first surrounding 24 is in contact with the rim transversal lower face 23b. According to one embodiment where the content C is disposed within a godet 22 having a top godet edge 22a, the rim 20that is to say the free transversal face 21a if there is one, or the rim transversal lower face 23b if there is no transversal free transversal face such as the face 21ainsofar as it is in contact with the top edge 22a of the godet 22, fulfills the function of establishing continuity between the bottom 7 and the godet 22, and also optionally of maintaining the godet 22 in position mechanically, by clamping the godet 22 between the rim 20 of the bottom 7 and the insert 6 (FIG. 1, 6, 7), the godet being in clamping contact with, and between, the rim 20 and the insert 6.

[0151] We refer to the cooperation of the bottom 7 and the cover 8 in closed configuration (FIG. 1, 6, 7, 18, 19). It is provided complementary shapes for the lower terminal portion 17a of the peripheral cover wall 17 and for a first recess 25 located at the upper portion 10a of the peripheral bottom wall 10 and directed towards the exterior and upwards. The first recess 25 of the bottom 7 is produced by means of the hollow angled external configuration formed by the transversal portion 52a and the axial portion 52b of the set back portion of rim 20a. The shapes of the lower terminal portion 17 and the first recess 25 are adapted to cooperate in closed configuration. The internal peripheral face 26a of the lower terminal portion 17a and the lateral peripheral face 26b of the first recess 25 (that is the external lateral peripheral face of the axial portion 52b) have adjusted and fitted surfaces. Such adjusted and fitted surfaces are sufficiently continuous and extended so that together in the closed configuration, they form an appropriate barrier preventing dust from entering the case LD. The transversal free face 27a of the lower terminal portion 17a and the transversal free face 27b of the first recess 25 (that is the upper face of the transversal portion 52a) are adjusted to form, on one hand, a blocking at the end of the pivoting closing movement to the closed configuration and, on the other hand, the joint plane 28 of the case 1, LC. The means to maintain 19 comprises complementary protrusions and grooves on the lateral peripheral face 26b and the exterior face 26b, at the opposite of the hinge 3 (FIG. 14) where the peripheral bottom wall 10 and the peripheral cover wall 17 may have a slight rounded indentation 55 at the location of the greatest distance between the bottom 7 and the cover 8 when opening the case and, where appropriate, the location of the entry of opening.

[0152] According to a possible but in no way limiting embodiment, as illustrated in FIG. 6, the distance h1 between the transversal free face 27b and the lower edge 11 and the distance h2 between the transversal free face 27a and the exterior face 29 of the transversal cover wall 16, are equal at 10%, in particular 5%. With this embodiment, the joint plane 28 of the case 1, LC is substantially halfway up the case 1, LC. The overall height of the bottom 7, h3, is around 20% to 30% more than the overall height, h4, of the cover 8. According to this possible but not limiting embodiment, in its intermediate manufacturing conformation, the bottom+cover+hinge component 5 has the lower edge 11 of the bottom 7 and the exterior face 29 of the transversal cover wall 16 which are more or less coplanar. According to another embodiment in which the internal axial height of the cover 8 is less, the lower edge 11 of the bottom 7 and the exterior face 29 of the transversal cover wall 16 shall be offset in the direction of the main axis A.

[0153] Consider now the hinge 3 with explicit reference to the drawings of FIGS. 1 to 6, 8, 9, 14 to 19. The hinge 3 is not of a conception in which there is only one single pivot axis element between two rigid elements so that the movement of the hinge providing the pivoting occurs locally precisely at the location of this one single pivot axis, while the rigid elements are not deformed. On the contrary, according to the invention, the hinge 3 is deformable as a whole, being arranged so that its deformation ensuring the pivoting movement occurs either continuously or discontinuouslyby means of at least two pivot zonesover an extent in a pivot axis space which is extended in the lateral transverse direction B. That is how must be construe pivot axis space. The hinge 3 extends between two free first edges spaced from each other along the lateral transverse direction B. In its intermediate manufacturing conformation (FIG. 8, 9), the hinge 3 extends in the transverse radial axis E between two second edges connected respectively to the bottom 7 and the cover 8, the connections being in one piece continuously. With a case 1 having a circular outline, the hinge 3 in flat situation (opened) has a front elevation outline in the shape of a diabolo (or butterfly), with a smallest width W, at the middle, along the transverse radial axis E, between its two curved second edges and with a greatest width at its two free first edges. The width W is wide enough to allow the pivotal movement of the hinge 3, with reference to the pivot axis space, which should be understood as being a greater or lesser variation in the curvature of the hinge 3, in its extent between the bottom 7 and the cover 8 corresponding to the pivot axis space. In the embodiment depicted on the drawings, the width W is around 3 mm, that is around an order of magnitude of more or less 10 times the thickness of the hinge 3. The opposite exterior faces respectively of the bottom 7 and of the cover 8 are spaced accordingly the width W. The hinge 3 is connected firstly to the peripheral bottom wall 10, at its upper portion 10a, within an upper second recess 30 directed towards the exterior and upwards and secondly to the peripheral cover wall 17 within a lower third recess 31 directed towards the exterior and downwards. In the closed configuration (FIGS. 1 to 4, 6, 18, 19), the hinge 3 registers substantially in the envelope formed by the exterior faces of the peripheral bottom wall 10 and the peripheral cover wall 17. The upper second recess 30 is formed in the lateral peripheral exterior face of the transversal portion 52a of the set back portion of rim 20a. The thickness e of the hinge is substantially constant over its entire extent along the transverse radial axis E (width W), including at its two second edges connected to the bottom 7 and to the cover 8, and without median line or zone of reduced thickness. If necessary, the thickness of the hinge may vary slightly along the lateral transverse direction B, between its two free first edges. In all cases, the thickness e of the hinge 3 (FIG. 17) is chosen so that the hinge 3 is sufficiently deformable and this depending the selection of material of the component 5. The thickness e of the hinge 3 is comprised between 0.3 mm and 0.8 mm, more particularly between about 0.4 mm and about 0.5 mm.

[0154] The thicknesses of the peripheral wall 10 of the bottom 7 and the transversal cover wall 16 and the peripheral wall 17 of the cover 8 can be equal or almost equal to a value t (FIG. 7). The thickness t of the walls, 10, 16, 17 is chosen so that the walls 10, 16, 17 are sufficiently rigid as a whole and this depending the selection of material of the component 5. So, the thickness t is significantly higher than the thickness e. As example, t may be comprised between around 1.5.e and 4.e, more particularly between 2.4.e and 3.e. According to one embodiment, t is equal or in order of magnitude of 1.2 mm. That gives to the bottom 7 and to the cover 8 a good rigidity and strength. The thickness of the rim 20 and the thickness of the set back portion of rim 20a can be equal or almost equal to the thickness t of the wall 10 and consequently are sufficiently rigid as a whole, like the wall 10. However, the radial thickness of the internal edge 21, as well as the radial width of free transversal face 21a, may be less that t, e.g., in one embodiment, around 0.5.t (FIG. 6). The radial width of the recesses 25, 30, 31 can be more or less around the half of the thickness t of the walls, 10, 16, 17.

[0155] As soon as the means to maintain 19 have been released, the spontaneous and natural maximum opening angle between the plan of the bottom 7 (plan of the rim 20) and the plan of the cover 8 (plan of the lower transversal cover opening 18) in opened configuration is comprised between around 115 and 145, not necessarily more, in particular between around 125 and 135, in particular around 130, while there is not provided a supplementary specific opening movement end stop of the cover 8 at the opening angle. With a right parallelepiped case, the hinge can extend more between its two free first edges in the lateral transverse direction B, or it may be provided two or more elementary hinges 3.

[0156] We refer to FIGS. 11 to 13 which represents the insert 6 in its manufacturing conformation. The insert 6 is one single monobloc plastic component which is integrally molded in a material identical, or almost identical, or equivalent to the material used for the component 5 and is rigid as a whole. As a result, the insert 6 has the qualities already mentioned resulting from the use of the material of component 5. When the bottom+cover+hinge component 5 is molded by a bi-injection process (or so-called 2K injection molding), the material of the insert 6 may be, according to one embodiment, the first material PP1 of the bottom 7, or at least is a sufficiently opaque material that hides the technical means of the insert 6. The component 5 (bottom+cover+hinge) and the component 6 (insert) are molded separately, may be possibly in a more or less contemporary way.

[0157] The insert 6 comprises a transversal insert wall 32 having an exterior lower face 40 and a top interior face 39a. The insert 6 comprises above the transversal insert wall 32 and in continuity with it, a lateral peripheral insert wall arrangement 34+49. According to one embodiment, the lateral peripheral insert wall arrangement 34+49 comprises an internal lateral peripheral insert wall 34 and an external lateral peripheral insert wall 49. The internal peripheral wall 34 has an internal peripheral face 39b, an external peripheral face and the top first surrounding 24 disposed transverse. The internal edge 24a of the top first surrounding 24 defines the outline of a transversal insert opening 36. The external peripheral wall 49 has an internal peripheral face, an external peripheral face 33 and a top second surrounding 50 disposed transverse. The internal peripheral wall 34 and the external peripheral wall 49 are concentric around the main axis A, with an annular insert space 51 between them. According one embodiment, the internal peripheral wall 34, the external peripheral wall 49 and the annular insert space 51 have radial thicknesses (or dimension for the space 51) which are identical or close and chosen so that the insert 6 is sufficiently rigid as a whole. According to one embodiment, the thickness of the transversal insert wall 32, the internal peripheral wall 34 and the external peripheral wall 49 is equal or close to the thickness t of the walls 10, 16 and 17 of the bottom 7 and the cover 8. The internal peripheral wall 34 has an axial height higher than the axial height of the external peripheral wall 49, the top first surrounding 24 being higher than the top second surrounding 50. According one embodiment, the ratio between the axial height of the internal peripheral wall 34 and the axial height of the external peripheral wall 49 is around 1.2 to 1.3. According to one embodiment, the insert 6 comprises distinct and spaced radial wings 35, located inside the annular space 51, in one-piece continuity with the transversal insert wall 32, the internal peripheral wall 34 and the external peripheral wall. 49. The wings 35 contribute to a stiffening function of the insert 6. Such a radial wing 35 is limited on the top by a small free upper face connecting the top first surrounding 24 and the top second surrounding 50, and, consequently, this free face is inclined with respect to the main axis A, from the exterior side to the interior side, and from bottom to top.

[0158] The insert 6 comprises also a means 37 for fixing the bottom 7 (or by ellipse means for fixing 37) which is located on the external peripheral face 33 of the external peripheral wall 49. The means for fixing 37 and the means for fixing 15 are designed to be structurally complementary in order to be able to cooperate so as to ensure the mutual fixation of the insert 6 and the bottom 7, and so the component 5.

[0159] The insert 6 comprises also a content holding face 38 (or by ellipse holding face 38) which limits a hollow which is opened upward at the transversal insert opening 36. Such hollow limited by the holding face 38 and having the transversal insert opening 36 forms and defines the storage space 2. The function of the holding face 38 is to hold the content C: its mass is supported on the holding face 38 and immobilized in position within the hollow of the storage space 2. As described below, the content C is accommodated either directly on the holding face 38 or indirectly because the content is firstly accommodated within a godet 22 and the godet 22 with the content is secondly accommodated within the hollow defined by the holding face 38. The holding face 38 comprises a transversal portion and a lateral peripheral portion 39b. The transversal portion of the holding face 38 is the main central portion of the top interior face 39a which is limited by the internal peripheral face 39b (consequently not comprising the annular portion of the top interior face 39a which is external to the external peripheral face of the internal peripheral wall 34). The lateral peripheral portion 39b of the holding face 38 is formed and defined by the internal peripheral face of the internal peripheral wall 34. The arrangement comprising the internal peripheral wall 34 with its internal peripheral face 39bthe function of which is to limit the storage space 2, the external peripheral wall 49 with its external peripheral face 33the function of which is to cooperate with the internal face of the peripheral bottom wall 10 so that they are rigidly fixed together, and the annular space 51, in combination makes it possible to provide two functional peripheral faces 39b and 33 which are properly spaced apart radially by the value of the sum of the thicknesses of the two internal 34 and external 49 peripheral walls and of the dimension radial of the annular space 51, by limiting the quantity of material used, thanks to the space 51, which is advantageous from an environmental point of view.

[0160] If desired, the storage space 2 may occupy all (or almost all) the hollow limited by the content holding face 38 so that the amount of content C relative to the volume of the case 1, LC can be maximized. We refer to FIGS. 1, 6, 7, 14 to 18 which depict the assembly of the component 5, i.e., its bottom 7, and the insert 6. Firstly, the internal peripheral face 10b of the wall 10 and the external peripheral face 33 of the external peripheral wall 49 have complementary adjusted surfaces that interlock. Secondly, the insert 6 is rigidly fixed transversely onto the bottom+cover+hinge component 5 with the respective means for fixing 15 and 37 located on their adjusted surfaces. The transversal insert wall 32 of the insert 6 extends and fits into the lower bottom opening 13. The means for fixing 15 and 37 are protrusions and grooves, or equivalent, located on the adjusted surfaces mentioned above. According to a first embodiment, the means for fixing 15 and 37 are irremovable so that the insert 6 is permanently fixed to the component 5. With this arrangement, the case 1 is not refillable and is discarded once the content C is consumed. According to a second embodiment, the means for fixing 15 and 37 are removable so that, once the content C is consumed, the insert 6 can be disconnected to the component 5 by means of an external action, for example with the help of the nail or a point or just pushing inside the compact to eject the insert 6, so that the case 1 can be refilled with a new mass of content C which, according to one embodiment is disposed in a godet 22. According to one other embodiment, the content is disposed in a new insert 6 which can replace the previous used insert which is discarded. Furthermore, the walls 10 and 49 are so dimensioned and the means for fixing 15 and 37 so located, that the lower edge 11 of the wall 10 and the exterior lower face 40 of the transversal insert wall 32 are coplanar. Or, it may be only just almost coplanar, the lower edge 11 of the wall 10 projecting slightly below the exterior lower face 40 so that, on one hand, the exterior lower face 40 is not a bearing face (of the case 1, LD) which could thus be damaged, on the other hand, a label can be attached on the exterior lower face 40 without being damaged by pressure or friction. With the insert 6 having the structure described above, that is having an internal peripheral wall 34 of axial height greater than the axial height of the external peripheral wall 49, the top first surrounding 24 being higher than the top second surrounding 50 and the wings 35 having upper faces free inclined, a space is provided upwards and at the periphery of the insert 6 for placing the set back portion of rim 20a and more particularly its protruding angle between its transversal portion 52a and its axial portion 52b.

[0161] We refer to the drawings of FIGS. 1, 6, 7, 11 to 13, 17 which show the insert 6 and the bottom 7 in the situation where they are assembled together, with the transversal insert wall 32 which extends and fits into the lower bottom opening 13. In this situation, the top first surrounding 24 of the insert 6, which is the upper part of the insert 6, is placed within a space closed from above provided by the bottom top rim 20 and is facing the rim transversal lower face 23b. The top second surrounding 50 of the insert 6 is facing the annular transversal lower face 53a of the transversal portion 52a of the set back portion of rim 20a. The small free upper faces of the wings 35 are located facing the protruding angle formed by the transversal portion 52a and the axial portion 52b of the set back portion 20a. The set back portion of rim 20a is thus placed in the space left by the insert 6, upwards and at its periphery, due to the axial height difference between the internal peripheral wall 34 and external peripheral wall 49. According to one embodiment, the top first surrounding 24 is located close the rim transversal lower face 23b and spaced to it, without contact. And the top second surrounding 50 is spaced to the annular transversal lower face 53a, without contact. So, there is no contact between the set back portion 20a and the insert 6.

[0162] According to a first embodiment (FIGS. 1, 11 to 13), the transversal insert wall 32 of the insert 6 is full, that means without opening. The storage space 2 is closed on the exterior lower face 40 of the transversal insert wall 32. The content C (possibly within the godet 22) is placed in the storage space 2 from above, through the transversal insert opening 36. According to a second embodiment (FIG. 14, 15), the transversal insert wall 32 comprises one small functional hole 42. The storage space 2 is opened (by means of the small hole 42) on the exterior lower face 40 of the transversal insert wall 32. The content C is placed in the storage space 2 from below, through the small hole 42 at the condition to be in fluid state for its injection (and dried later), the loaded case LD having no godet 22. The hole 42 may be used when the loaded case LD has a godet 22 in order to disconnect an empty godet 22 from the insert 6 by introduction within the hole 42 of a small stem capable to push the godet 22. That arrangement is combined with that in which the means for fixing 15 and 37 are removable so that the case 1 is refillable.

[0163] We refer to the accommodation of the content C in the storage space 2. According to a first embodiment (FIG. 16, 18), the mass of the content C is accommodated directly on the holding face 38, i.e., without any godet. According to a second embodiment (FIG. 1, 5, 6, 7), the mass of the content C is accommodated firstly within a separate godet 22 and thereafter the godet 22 with the content C is accommodated on the content holding face 38. The godet 22 has a transversal godet wall, a lateral peripheral godet wall located above the transversal godet wall, which is terminated by a top godet edge 22a, and an access top godet opening limited by the top godet edge 22a. The peripheral godet wall and the transversal godet wall define and limit a hollow capable to receive the content C. The godet 22 is a separate part of the insert 6. It has an outer shape which is complementary to the holding face 38. The godet 22 is located in contact with the transversal portion of the holding face 38 and, if not in loose contact, close to the lateral peripheral portion 39b of the holding face 38, with a radial transverse play allowing it to be put in place. The free transversal face 21a of the rim 20 can be an axial stop upwards of the top godet edge 22a and a fixing and immobilizing mechanical means of the godet 22 to the bottom 7 (and so to the component 5) avoiding any unwanted movement of the godet 22 when it is placed within the bottom 7. That is because, with appropriate axial positions and dimensions of the bottom 7 and the insert 6 (and their constitutive parts), the rim 20 of the bottom 7 can exert a vertical downwardly force on the godet 22, via the respective faces 21a and 22a in contact, with the effect to establish a hold-in-position contact between the transversal godet wall and the transversal insert wall 32 which is itself in hold-in-position contact with the bottom 7. With this arrangement, the godet 22 is maintained in position mechanically by clamping between the rim 20 of the bottom 7 and the insert 6. This holding-in-position of the godet 22 may be effective without requiring any other means of attachment for example glue. That is advantageous for environmental purpose. The godet 22 can be made of aluminum or equivalent material, of low thickness. For environmental purpose, the godet 22 and the insert 6 can be disassembled and each appropriately recycled. According to possible different embodiments, the godet 22 is the combination of several elementary godets arranged side by side and containing different contents, in particular four elementary godets. Such elementary godets, when arranged together properly, may have a global shape and dimensions equivalent to the global shape and dimensions of a godet when the case LD has a single godet, or/and such elementary godets have identical or similar dimensions or, on the contrary different dimensions because at least one is larger than the other or one is smaller than the other.

[0164] According to one embodiment (FIGS. 1, 5, 6, 7, 12, 13, 16 to 18) it is provided on the internal face of the transversal portion of the holding face 38, a series of grooves 43 (and so, protrusions). They may be annular. The grooves 43 facilitate the attachment of the content C when it is accommodated directly on the holding face 38, because the material of the content fills the grooves 43 to which the material of the content C is attached. The grooves 43 can be used, if desired, to secure or help to secure, with the means of glue, a godet 22 when the content C is accommodated indirectly on the holding face 38, by means of a godet 22. Either the product of the content C can fill the grooves 43, or the grooves 43 can capture a glue capable to secure or help to secure the godet 22 on the insert 6. However, according to one other embodiment, described above, the godet 22 is not glued for fixing, but fixed mechanically by clamping between the rim 20 of the bottom 7 and the insert 6. According to another embodiment (FIG. 14), it is provided protrusions (and so, grooves 52) on the exterior lower face 40 of the transversal insert wall 32, adapted to fix a label on the case 1, LD. Such grooves 52 may be annular and make it possible to limit the amount of material constituting the insert 6 without affecting its strength.

[0165] According to the embodiment of FIG. 6, 8, 10, 13, it is provided at least one radial (or more or less radial) protrusion 44a (on FIG. 10, two almost radial protrusions 44a, spaced apart from each other in proximity to each other) on the internal peripheral face 10b of the wall 10 which can cooperate with at least one notch 44b provided into the transversal insert wall 32 and the external peripheral insert wall 49, in order to orientate the insert 6, and so the content C, relatively to the bottom 7, around the main axis A. This orientation is useful when the free upper surface 4 of the content C is provided with a logo, patterns, or signs (for information or commercial or decorative purposes) obtained directly on the product of the content C (for example by pressing). Such logo, patterns, or signs are also a content tamper evident indicator.

[0166] As depicted on FIGS. 16 to 18, the free upper surface 4 of the content C (not yet consumed) may be located in the plane of the transversal insert opening 36 or in the close neighboring of such plane. With the embodiment in which the content C is accommodated directly on the holding face 38, the free upper surface 4 of the content C may be located in the plane of the top first surrounding 24 or a little below this plane, by depending on the degree of filling desired. According to one embodiment, the falling portion of the internal edge 21 with its free face 21a is prevented from penetrating into the content C. With the embodiment in which the content C is accommodated indirectly on the holding face 38, by means of a godet 22, the free upper surface 4 of the content C may be located in the plane of the top godet edge 22a or a little below this plane, by depending on the degree of filling desired. In the direction of the main axis A, the content C can thus have a thickness of up to about 40% the total height of the bottom 7, considering the thickness of the rim 20 and the transversal insert wall 32. In radial direction, the content C can have a diameter d of up to about 75%, more particularly up to around 85%, of the external diameter D of the rim 20. The amount of content C is thus maximized. According to one possibility, the radial dimension of the rim 20 is sufficient to allow the insert peripheral wall 34 to be placed in plum line.

[0167] The existence of the material parts of the components 5 and 6, and of the godet 22 if it is provided (and therefore the existence of the parts without material), the size, the shape and the relative arrangement of these parts make it possible to achieve a case having the desired characteristics, and in particular its compactness, its simplicity, its ecological dimension, and its opening as described.

[0168] The manufacturing process of a case 1 as described above needs to a starting point where one have available a bottom+cover+hinge component 5 in its manufacturing conformation (closed configuration) as represented on FIG. 19, and an insert 6, as represented on FIG. 11, disassembled (FIG. 23). Thereafter one fill the storage space 2 of the insert 6 with the content C (symbolized by the arrow F of FIG. 23) (without or with a godet according to the embodiments, as described below). Thereafter, and finally, one introduce the insert 6 with the content C (without or with a godet according to the embodiments, as described below) within the lower bottom opening 13 till it is located within the hollow 9 of the bottom 7 and till the means for fixing 15 and 37 cooperate (symbolized by the arrow I of FIG. 24). The loaded case LD so manufactured is as it is depicted on FIG. 18. In the embodiment where there is a godet 22, the godet 22 may be fixed mechanically by clamping between the rim 20 of the bottom 7 and the insert 6 without glue. Or possibly, according to another embodiment, it may be used glue.

[0169] Several different possibilities are offered to fill the content C within the storage space 2 of the insert 6. One embodiment is hot pour directly the content C into the storage space 2, from above, via the transversal insert opening 36. One other embodiment is compressing the content C into powder state into the storage space 2, from above, via the transversal insert opening 36. One other embodiment is injecting the content C at a fluid state into the storage space 2 from below, through the hole 42 of the transversal insert wall 32. One other embodiment is compressing the content C into powder state into a godet 22 from above the godet 22 and thereafter placing the godet 22 with the content C into the storage space 2, from below, via the lower bottom opening 13.

[0170] The manufacturing process to have available a bottom+cover+hinge component 5 in its manufacturing conformation (closed configuration) is the following. As represented symbolically on FIG. 20, one has available a molding apparatus with at least two parts 45, i.e., a fix part on the injection side and a movable part on the ejection side of a molding apparatus, and injection means, and with at least one mold cavity 46 having an inner shape complementary to the shape of the bottom+cover+hinge component 5 in its flat fully opened configuration represented on FIG. 8. One has available molding plastic material selected as described above. Following (FIG. 21), one mold the molding material in the mold cavity 46 to obtain a bottom+cover+hinge component 5 in its intermediate manufacturing conformation in which it is fully opened flat at 180 (FIG. 8). Following (FIG. 22), one pivot at 180 the bottom 7 and the cover 8, relatively to each other, by means of the hinge 3 with reference to the pivot axis space, from such intermediate manufacturing conformation (symbolized by the arrow CA FIG. 22). At the end of the pivotal movement, the bottom+cover+hinge component 5 is in its manufacturing conformation (closed configuration), ready to receive the insert 6 and the content C in its storage space 2, as described above.

[0171] As regards the molding step, it may be a bi-injection process (or so-called 2K injection molding) with a first material PP1 for the bottom 7 and a second material PP2 for the cover 8 and the hinge 3. As represented on FIG. 21, one used a molding apparatus with two injection holes 47a and 47b on the same side of one part of the mold. One injection hole 47a is located towards the bottom 7, opposite the hinge 3, and the other 47b towards the internal central part of the transversal wall of the cover 8. A movable bridge or dam 48 can separate the two sub-cavities where the first material PP1 and the second material PP2 must be injected.

[0172] As regards the step of the 180 pivotal movement, it is made, it takes place at a time when the bottom+cover+hinge component 5, being in its intermediate manufacturing conformation, is still hot, at a precise temperature, kept stable by timing and manufacturing conditions. Such 180 pivotal movement is made immediately after molding or after a very short delay after molding (a few seconds or maximum one or two minutes). This step is made either when the bottom+cover+hinge component 5 in its intermediate manufacturing conformation is still in the mold cavity 46 or after it has been removed or ejected from the mold cavity 46 and deposited on a handling tool.

[0173] According to one embodiment, it is possible to have in-mold decoration on the case 1, more specially the cover 8, with the installation of a decorated film in the mold in front of the injection hole. More generally, the in-mold decoration is applied for the bottom 7 and/or the cover 8 and/or the insert 6.
