## Title
Container for the motion of a double stick with a single stick holder

## Abstract

A container with a roto-translatory motion of a stick holder (1) provided with a pair of opposed sticks (3, 3′) in comparison with the support surface plane (4) and upper (5) and lower (5′) pins, that axially slide inside an intermediate body (7), provided with vertical grooves (11, 11′) inside its central wall (10) and slits (8, 8′) and (9, 9′) on its upper (7′) and lower (7′′) portions rotating in the inside of a pair of outer bodies (13, 13′). The pins (5, 5′) slide inside annular grooves (14, 14′), helicoidal groove (16, 16′) and (17, 17′) made in the inner wall of these outer bodies (13, 13′), such that the pair of sticks (3, 3′) can be controlled to come out from both ends, upper (7′) and lower (7′′) portions of the intermediate body, when the ends are apart from the respective caps/bases (22, 22′) of covering.

## Background
The invention consists in a container for the motion of a double stick with a single stick holder, mostly for cosmetic use, for example for stick products, by which the stick holder body is controlled with a roto-translatory motion that alternatively makes both container ends come out, when each end is free from its caps.
Such a container is useful for controlling, with only one mechanism, the motion of two identical sticks, similar or different from each other or of a stick from one side and an instrumental cosmetic applicator to the other, for example: brush, sponge, eyeliner, mascara, pencil, etc., where the stick products could be: red for lips, lip-pomade, cheek product, eyes area product, lead, deodorant products, body product, and similar, etc.
It is known that there are containers on the market that are capable of controlling two products in sticks, for example red for lips, made with two containers, each provided with its separate mechanism, opposite to each other and made integral, so having independent mechanism between them.
The present invention differs from the preceding artworks because it is provided with an only mechanism that allows to have the motion of a single stick holder towards opposite ends compared with its central area, a non usable area that is usually utilized for the closure of both caps, therefore both sticks, in an opposite position, move together in both ends, where if one stick comes out the other follows sliding in the inside of the container.
The present invention allows to have, in respect to the preceding artworks, a noticeable price savings, the price due to less number of pieces used and also thanks to a reduced total of length/height, because it is provided with a single stick holder and an only intermediate body, instead of two stick holders and of two intermediate bodies.

In FIGS. 1, 2, 2a, 2b, 2c and 3, the stick holder 1 has a tubular body 2, with both ends open, and of a central plan of support surface 4 of respective double sticks of cosmetic products 3 and 3′, consists in two opposed portions of annular edges 4 and 4′ directed through the axle, and at least of a pair of pins guide, upper 5, and lower 5′, made on the outer wall of tubular body 2, arranged in opposite position in respect to the axle, with a definite distance, in respect to the central plane of the supporting surface 4 of the double sticks.
Two opposite openings 6 and 6′ obtained between the two opposed positions of annular edges 4 and 4′, that function as air discharge when each end of the two sticks 3 and 3′ are inserted to lean on these double opposed portions of annular edges.
On the inner wall of the tubular body 2 there can be obtained, along its circumference, vertical ribs to anchor in a stable position the two bottoms opposed sticks.
FIG. 4 illustrates the variation of FIG. 3, where the stick of cosmetic product 3 has been contrasted with an application tool of cosmetic product 3a, consisting for example in a brush for cosmetic use.
To better anchor in a stable position the two opposed bottoms of sticks 3, 3′, or of stick 3 with a opposed application tool of the cosmetic product 3a, could be useful, during the assembling operation, interposing between the two bottoms, a solid product 3′′, for example non-limitative in:
a) a dripping of the melted cosmetic product, that amalgamates with the two stick bottoms of the same cosmetic product, creating a single body during its cooling,
b) an amalgam of different product that has in any case the purpose to create a single body with both bottoms of the sticks. FIGS. 5, 5a, 5b, and 5c illustrate the intermediate body 7, tubular, provided with:

    
    
        a pair of guide slits 8 and 8′, opposite, verticals, realised on its portion of upper tubular wall 7′, of minor diameter;

FIGS. 7a and 7b illustrate a pair of outer bodies, upper 13 and lower 13′, tubular with open ends, same, separated and put in opposed position, provided of:

    
    
        a pair of portions of internal annular grooves 14 and 14′, interrupted by internal respective relieves in the shape of an inclined tooth 15 and 15′;
        a pair of helicoidal internal grooves 16 and 16′;
        a pair of helicoidal internal grooves 17 and 17′, asymmetrically opposite to the pair of internal helicoidal grooves 16 and 16′.
    
    


In the figures it is illustrated a container with suitable proportions for a pair of sticks 3, 3′ of cosmetic product for lips.
Changing the proportions of the stick holder 1, reducing its diameter, as illustrated in FIG. 8, it can be made a container for stick 3 in the shape of a style, or a lead, of reduced diameter and lengthened shape, suitable for lips or eyes area, eventually with an application tool of opposed cosmetic product, that consists in a small bar provided with a small sponge 3b or, as illustrated in FIG. 8a, a small bar provided with a mascara 3c, or as illustrated in FIG. 9, of a lead 3d, or of a small brush, or similar tools for the application of a cosmetic product, where these last eventual variations are not illustrated in the attached designs.
Changing the proportions of the stick holder 1, increasing its diameter, it can also be made a container for stick 3 of large diameter and lengthened shape suitable for cheeks or body area, eventually with an application tool of opposed cosmetic product, that consists in a brush 3a or eventually with a small body sponge, where said last eventual application tool variation is not illustrated in the attached designs.
FIG. 10 illustrates portions of sections used to distinguish the plane development of the circumference of the inner walls of the roto-translatory mechanism:

    
    
        a pair of outer bodies, upper 13a and lower 13′a, with inclined hatched spaced at 0°,
        intermediate body, upper 7′a, lower 7′′a, hatched with spaced dots,
        central wall 10a of the intermediate body 7, positioned between the upper 7′a and lower 7′′a portions, with dense hatched dots,

FIG. 11 illustrates, in a front section view, the roto-translatory drive mechanism obtained through the assemblage of the bodies of FIG. 6 with the outer bodies of FIGS. 7a and 7b. 
FIG. 11a illustrates the plane development of the circumference of the inner walls of the roto-translatory drive mechanism according to FIG. 11.
The plane development of the circumference of the inner walls of the pair of outer bodies, upper 13 and lower 13′, of FIGS. 7a and 7b, same, separated and put in a opposed position, are represented by surfaces, respectively upper 13a and lower 13′a, that in the figure, to be clear, are developed as a multiple, equal to 2,5, of 360° and are provided with grooves realised in each internal tubular walls, which are:

    
    
        a pair of portion of annular grooves 14 and 14′ adjacent to each open end faced towards the central wall 10a, interrupted by respective internal relieves, for example in the shape of an inclined tooth 15 and 15′;
        a pair of helicoidal internal grooves 16 and 16′ with ends that:
    
    


a) from one side they cross the pair of annular grooves 14 and 14′, in an adjacent position towards the internal relieves in the shape of an inclined tooth 15 and 15′, so that a side of the inclined tooth 15 or 15′ is the continuation of the side of the helicoidal groove 16 or 16′,
b) on the other side they stop at a final distance a bit before the internal annular steps 18 and 18′, adjacent to each open end faced towards the outside;

    
    
        a pair of helicoidal internal grooves 17 and 17′ asymmetrically opposite to the pair of helicoidal internal grooves 16 and 16′, with ends that:
    
    


a) from one side they cross the pair of annular grooves 14 and 14′,
b) on the other side they stop at a final distance a bit before the internal annular steps 18 and 18′, said final distance lower of a distance “D” in respect to the final one of the pair of the helicoidal internal groove 16 or 16′ and equal to the distance “D” between the guide pins pair 5 and 5′.
On the plane development of the circumference of the inner walls of the pair of upper outer bodies 13 and lower 13′, its superimposes the plane development of the circumference of the inner wall of the intermediate body 7 and of the central wall 10, of FIGS. 5, 5a, 5b, and 5c. 
These plan developments are represented from a surface that develops up to 360°, and indicated with:

    
    
        7′a, upper portion, of minor outer diameter, provided with a pair of guide slits opposite upper 8 and 8′, verticals,
        7′′a lower portion, of minor outer diameter, provided with a pair of guide slits opposite lower 9 and 9′, verticals,
        10a central wall, that keeps a distance from the pair of upper and lower portions 7′, 7′′, of major outer diameter, provided with grooves 11 and 11′, verticals, in line and in continuing of these pair of guide slits opposite 8 and 8′ and 9, 9′, realised in the internal tubular wall.
    
    


Slit 8 cuts the upper outer annular tooth 12, provided in correspondence with the upper end of the plane development 7′a upper of the circumference of the internal wall of the intermediate body 7, while the lower slit 9 extends as a near limit of the lower outer annular tooth 12′, without cutting it.
Symmetrically slit 9′ cuts the lower outer annular tooth 12′, provided in correspondence to the lower end of the plane development 7′′a lower of the circumference of the inner wall of the intermediate body 7, while the upper slit 8′ extends as a close limit of the upper outer annular tooth 12, without cutting it.
On the plane development of the circumference of the inner wall of the intermediate body 7, superimposes the plane development of the circumference of the inner wall of the stick holder 1 of FIGS. 2, 2a, 2b, 2c and 3.
Said plane development being designed without the two opposing portions of annular edges 4 and 4′, without the opposite openings 6 and 6′ and without the opposed sticks 3 and 3′. It is represented by a surface that develops up to 180°, and indicated with the reference 1a and is provided with a pair of guide pins 5 and 5′, arranged in opposed position with a distance of “D/2” in comparison with the central level of the support surface 4, so that the pin of guide 5′ be in an lower position and the opposed pin of guide 5 be in a upper position.
In FIG. 11 the stick holder 1 is represented in the centre of the roto-translatory mechanism in its position of non-use with the two opposed sticks 3 an 3′ both put in an internal position.
Correspondingly in FIG. 11a the lower pin of guide 5′ is positioned in a way that it crosses the lower guide slits 9 of the lower intermediate body 7′′a to get inserted into the lower annular grooves 14′ of the lower outer body 13′a, while the upper pin of guide 5 is positioned in a way that it crosses the upper guide slits 8′ of the upper intermediate body 7′a to get inserted in the upper annular groove 14 of the upper outer body 13a. It is made, in said position of exchange, the possibility for the stick holder to be controlled to move towards the upper or the lower ends.
When the pin of guides 5 and 5′ slide in the annular grooves 14 and 14′, not until the inclined teeth 15, 15′ meet, the stick holder 1 has no possibility of moving vertically in one direction or the other.
To avoid that the stick holder in a non-use position could be free to accidentally move on the axle, stopping means have been made, surmountable with a control of mutual rotation between one of the two outer tubular bodies 13a or 13′a and the central wall 10, consisting in, at least one, slight relieves 19 and 19′ made inside the annular groove 14 and 14′ in an outer position and adjacent to the guide pins 5 and 5′ in a non-use position.
If mutual rotating motions are impressed between the outer tubular bodies 13, or 13′ and the central wall 10 in the roto-translatory control mechanism of FIG. 11, the line of translational sliding can be analyzed, horizontal 20, inclined 20′, of the guide pins 5 and 5′, and therefore of the relative motion of the stick holder 1, through the slits and the grooves represented on the plane development of the circumference of the inner walls of the roto-translatory control mechanism of FIG. 11a. 
If, for example, a mutual rotating motion is impressed between the outer upper body 13 and the central wall 10 of FIG. 11 in a way that, as it is illustrated in FIG. 11a, the central wall 10a and the respective portions, upper 7′a and lower 7′′a, of the intermediate body, they move towards the left, we obtain that:
a) the upper pin 5 covers a brief distance of horizontal translatory sliding 20, along the upper annular groove 14 of the outer upper body 13a, standing still without a vertical translation inside the upper slit 8′ of the intermediate upper body 7′a, to meet in its way the inclined tooth 15. Said inclined tooth 15 modifies the path of the upper pin 5 on the inclined translatory sliding 20′ line, along the helicoidal groove 16 of the upper outer body 13a, with a corresponding beginning of vertical translation towards the top, inside the upper slit 8′;
b) correspondingly, the lower pin 5′ covers the same brief distance of horizontal translatory sliding 20, along the lower annular groove 14′ of the outer lower body 13′a, standing still without a vertical translation inside the lower slit 9 of the lower intermediate body 7′′a, to follow parallely, controlled by the other upper pin 5, the same distance of the translatory sliding inclined 20′ line along the free area between the pair of the outer bodies 13 and 13′a, with a corresponding beginning of vertical translation towards the top, inside groove 11 of the central wall 10a, then slides along the helicoidal groove 17 of the upper outer body 13a, with a corresponding vertical translation towards the top, inside the upper slit 8.
Continuing the move towards the left we obtain, as illustrated in FIGS. 12 and 12a, that:
a) the upper pin 5 stops at the upper limit of the helicoidal groove 16, adjacent to the internal annular step 18 of the upper outer body 13a, and near the upper outer annular tooth 12 of the upper intermediate body 7′a; 
b) correspondingly, the lower pin 5′ stops at the upper limit of the helicoidal groove 17, of an lower height equal to the distance “D” in comparison with the upper limit of the helicoidal groove 16.
In that position the stick holder 1 is completely translated towards the top, with its upper edge projected in comparison with the upper outer annular tooth 12 of the upper intermediate body 7′a, with its stick 3 completely out in upper position, while the opposed stick 3′ stays in an internal position to the upper intermediate body 7′a. 
Inverting the motion towards the right, of the central wall 10a and of the respective portions, upper 7′a and lower 7′′a, of the intermediate body, with a mutual rotating motion in comparison with the upper outer tubular body 13, we obtain that pins 5 and 5′, and the relative stick holder 1, lower along the respective annular grooves 16 and 17, and upper vertical slits 8′ and 8, turn back to the starting point, as it is illustrated in FIGS. 11 and 11a. 
Continuing the motion towards the right, of the central wall 10a and of its portions, upper 7′a and lower 7′′a, of the intermediate body, besides the non-use position, and forcing the slight relieves 19 and 19′ made inside the annular grooves 14 and 14′, the guide pins 5 e 5′ cover, along these internal annular grooves 14 and 14′, the horizontal lines of translational sliding 20 until they meet, to stop however, the inclined tooth 15.
If instead, for example, a mutual rotating motion is impressed between the lower outer tubular body 13′ and the central wall 10 and its intermediate body, upper portion 7′, lower portion 7′′, of FIG. 11 so that, as it is illustrated in FIG. 11a, the central wall 10a and the respective portions, upper 7′a and lower 7′′a, of the intermediate body move towards the right, we obtain that:
a) the lower pin 5′ covers a brief distance of translatory sliding horizontal 20, along the lower annular groove 14′ of the outer lower body 13′a, standing still without a vertical translation inside the lower slit 9 of the intermediate lower body 7′′a, to meet in its way the inclined tooth 15′. Said inclined tooth 15′ modifies the way of the lower pin 5′ on the translatory sliding inclined 20′ line, along the helicoidal groove 16′ of the outer lower body 13′a, with a corresponding beginning of vertical translation towards the bottom, inside the lower slit 9;
b) correspondingly, the upper pin 5 covers the same brief distance of horizontal translatory sliding 20, along the upper annular groove 14 of the upper outer body 13a, standing still without a vertical translation inside the upper slit 8′ of the intermediate upper body 7′a, to follow parallely, controlled by the other lower pin 5′, the same distance of the inclined translatory sliding 20′ line along the free area between the pair of the outer bodies 13 and 13′a, with a corresponding beginning of vertical translation towards the bottom, inside groove 11′ of the central wall 10a, then to slide along the helicoidal groove 17′ of the lower outer body 13′a, with a corresponding vertical translation towards the bottom, inside the lower slit 9′.
Continuing the motion of the central wall 10a and of respective portions, upper 7′a and lower 7′′a, of the intermediate body towards the right we obtain, as illustrated in FIGS. 13 and 13a, that:
a) the lower pin 5′ stops at the lower limit of the helicoidal groove 16′, adjacent to the internal annular step 18′ of the lower outer body 13′a, and near the lower outer annular tooth 12′ of the lower intermediate body 7′′a; 
b) correspondingly, the upper pin 5 stops at the lower limit of the helicoidal groove 17′, of an lower height equal to the distance “D” in comparison with the lower limit of the helicoidal groove 16′.
In that position the stick holder 1 is completely translated towards the bottom, with its lower edge projected in respect to the lower outer annular tooth 12′ of the lower intermediate body 7′′a, with its stick 3′ completely out in lower position, while the opposed stick 3 stays in an internal position to the lower intermediate body 7′′a. 
Inverting the motion of the central wall 10a and of the respective portions, upper 7′a and lower 7′′a, of the intermediate body towards the left, with a mutual rotating motion in respect to the lower outer tubular body 13′a, we obtain that pins 5′ and 5, and the relative stick holder 1, rise along the respective annular grooves 16′ and 17′, and vertical slits 9 and 9′, to return to the starting point, as it is illustrated in FIGS. 11 and 11a. 
Continuing the motion of the central wall 10a and of the respective portions, upper 7′a and lower 7′′a, of the intermediate body towards the left, besides the non-use position, and forcing the slight relieves 19′ and 19, made inside the annular grooves 14′ and 14, the guide pins 5′ e 5 cover, along these annular grooves 14′ and 14, the horizontal lines of translatory sliding 20 until they meet, to stop however, the inclined tooth 15′.
If instead, for example, a mutual rotating motion is impressed between the two outer bodies, upper 13 and lower 13′, without committing or being integral with them the central wall 10 and its respective portions, upper portion 7′a and lower portion 7′′a, of the intermediate body of FIG. 11 so that, as it is illustrated in FIG. 11a, the upper outer body 13a moves towards the right or the left in respect of the corresponding opposite lower outer body 13′a, we obtain that the pins 5 and 5′ cover only the way of the horizontal translatory sliding 20, along these annular grooves 14′ and 14 of the respective outer bodies upper 13a and interior 13′a, staying still without axial translation inside the respective slits 8′ and 9 of the intermediate body 7′a and 7′′a until they find in their paths the respective inclined teeth 15 and 15′, for stopping.
A mutual motion only between the two opposite outer bodies, upper 13 and lower 13′, without letting the central wall 10 and the respective portions, upper 7′a and lower 7′′a of the intermediate body of FIG. 11 be integral with one of them, it does not impress an axial translation motion, towards the top or towards the bottom, of pins 5, 5′ and of its stick holder 1.
Said motion of axial translation is possible only with a reciprocal motion between the central wall 10 and the respective portions, upper 7′a and lower 7′′a, of the intermediate body, in respect of one of the two opposite outer bodies, 13 or 13′.
FIG. 14 illustrates the roto-translatory mechanism of FIG. 11 in which the pair of outer bodies 13, 13′, having internal helicoidal grooves, are covered with a pair of metal tubular shells covering 21 and 21′, with the purpose of improving the finishing appearance touch of the container.
FIG. 15 illustrates the roto-translatory mechanism of FIG. 14 provided with the lower cap/base 22′, one of the two caps/bases having simultaneous function as cap as well as of base, consisting in a tubular body having a upper open end and a closed lower one, inserted in the lower portion of the roto-translatory mechanism so that it covers the outer body 13′ when closing it, and its relative metal shell covering 21′, until it becomes fixed on the edge of the central wall 10.
Said cap/base 22′ is provided, on its inner bottom, with annular sectors 23′ projected towards its open end so that when closing the open ends of these sectors of annular walls can adhere elastically, with a determinate friction, on the inner tubular wall of the lower intermediate body 7′′, said friction can make integral the lower intermediate body 7′′ and the cap/base 22′.
The roto-translatory motion of the stick holder, besides being exercised by the reciprocal motion between the upper outer body 13 and the central wall 10, can be also exercised by the reciprocal motion between the upper outer body 13 and the cap/base 22′, because said last one has been made integral through the friction to the central wall 10 and to the respective portions, upper 7′a and lower 7′′a, of the intermediate body.
FIG. 16 illustrates the container of FIG. 15 in which, following up a mutual rotating motion between the upper outer body 13 and central wall 10 or the cap/base 22′, the stick holder 1 is completely translated towards the upper open end of said container, with its upper edge projected in comparison with the upper outer annular tooth 12 of the upper intermediate body 7′.
Its upper stick 3 is completely out in upper position, while the opposed lower stick 3′ remains in an internal position of the upper intermediate body 7′.
FIG. 17 illustrates the roto-translatory mechanism of FIG. 14 in which the cap/base 22 is inserted in closing on the upper portion of the roto-translatory mechanism so that the sectors of annular walls 23, projected from its inner bottom towards its open end, have been inserted with a determinate friction on the inner wall of the upper intermediate body 7′, said friction makes integral said cap/base 22 with said upper intermediate body 7′.
Following a reciprocal roto-translatory motion, between the lower outer body 13′ and the central wall 10 or the cap/base 22, the stick holder 1 is completely translated towards the open lower end of said container, with its lower edge projected in comparison with the lower outer annular tooth 12′ of the lower intermediate body 7′′.
Its lower 3′ stick is completely out in lower position, while the opposed upper stick 3 stands in an internal position of the lower intermediate body 7′′.
FIG. 18 illustrates the plain view, only the left half, enlarged with scale 2:1, according to the XVIII-XVIII plan, of the only two bodies lower cap 22′ and lower end inner body 7′′ of FIG. 16, where to simplify the representation the metal tubular shell body 21 and the outer lower body 13′ are not illustrated.
What has been illustrated for the lower end is also valid for the opposed upper end, to show how to improve the means act to make more solid, without the possibility of reciprocal annular sliding, the caps/bases, 22, 22′, with the intermediate body, through the upper ends 7′ and lower 7′′.
These means, consist in a knurling or series of ribs 24, for example verticals, made on the ends of the inner wall 7′ and 7′′, bounded with a corresponding knurling or series of ribs 25, for example verticals, made on the ends of the outer walls of the annular sectors, 23, 23′, in the inner bottom of the caps/bases 22, 22′.
