According to the above mentioned

it was developed, the box object of this patent of Invention

Privilege which will be detailed described with reference to the draws below related wherein: figure 1 illustrates a general view of the box in question; figure 2 illustrates a schematic and open general view of the box hereby treated, being it in its initial position before activation, such figure 2 includes a wide and in cut detail that is taken from direction pulley of the present box; figure 3 illustrates a similar view to the reported in previous figure, but showing box activation hereby treated; figure 4 illustrates the box in question at the moment in which a piece of floss is being pulled; figure 5 illustrates a partial view similar and in perspective of internal device of the box here treated being it in its initial stage before its activation; figure 6 illustrates a view similar to the one mentioned in the previous figure where it is showed device activation that exposes floss to consumer ; and figure 7 illustrates a schematic detailed and in perspective of the bottom of the box at the moment of the floss exposition figure 8 illustrates a general schematic and open view of a variation of the floss box herein presented, being it in its initial stage, before its activation; figure 9 illustrates a schematic detail of the variation of

figure 8 where it depicted the cutting device that is fixed in the pulley; figure 10 illustrates a schematic detailed and in perspective of the bottom of the variation of the box depicted in figures 8 and 9 , in a moment in which the floss is being expelled; and figure 11 illustrates a cutting A-A from figure 8.

According to how much the figures above mentioned illustrate, the improvement in floss box for public places object of this patent of Invention Privilege comprises a general structure 1 that is defined by a base 2 to be mounted against the wall , and a cover 3 defined in a way to recover all box internal devices .

Base 2 incorporates a support of mounting 4 where it is placed a bobbin 5 , which can present movement of spinning, or alternatively cannot present rolling movement, since its vertical positioning allows floss X to be naturally unrolled as it is tracked down. Base 2 receives montage of a direction pulley 6 which is fixed together with an axis 7 centered over base 2 , said pulley having small channel 8 (visible specifically in details in cutting that integrates figure 2) in the bottom of which, differently of what was shown in state of art ; it is contemplated a perimeter cavity 9, in order to serve as a place for natural housing and related to imprisonment of floss X when it is in touch with direction pulley 6.

Referred perimeter cavity 9 retains floss X along with periphery of direction pulley 6 making the said floss X to assume a more favorable condition at the moment of its exposition due to expelling device 10 action .

Direction pulley 6 , according to what was shown in the state of art , presents a cutting 11 analogue to cut 5C present in the box belonging to patent request MU 8100772- 8 , the same for cut device 12 that executes in an automatic way the cut of floss X at the appropriate moment .

Improved box hereby treated counts on a activation lever 13 similar to activation lever 6 contemplated in the before mentioned, being now, in the present case, activation lever 13 operates an activation device 14 of direction pulley 6 totally diverse from what was shown in state of art .

In the present invention, activation device 14 of direction pulley 6 comprises a lock 15 that spins around a pivot 16 , being that the referred lock 15 comprises a blade 17 that operates against an action of a spring 18 , said blade 17 is moved, in a given moment by a pin 19 that is mounted in the back face of direction pulley 6. The function of lock 15 is to stop direction pulley 6 , which spins normally in anticlockwise , from spinning in the opposite way for any reason .

By systematic of function of present box, activation pulley rotation 6 sets that in a

specific moment , its pin 19 gets in touch with blade 17 , which has a cavity that stops pin 19 , after reaching a specific point , from returning due to activation pulley spin in an inverse way from the normal . By reaching ideal point , direction pulley 6 only can be spinned by the action of the activation lever 13 that works against the action of a spring 23.

The spin of direction pulley 6 due to lowering of lever 13 makes expelling device 10 to be also activated .

Expelling device 10 can be better appreciated in the figures 5 and 6 , and it is formed by a folded metallic pole 20 that is mounted in a support 21 , being connected to an arm 22 that is connected to the lock 15.

When lever 13 is lowered, it moves lever 15 also down, which also displace down arm 22 that is connected to one of the ends of the pole 20 , and such movement making the opposed end of pole 20 , which is responsible by expelling the floss X, to be compressed against direction pulley 6 back face . The end of the pole 20 that contacts with floss X and that is indicated by reference 20 ' , such as specifically indicated in figures 6 and 7 , presents a similar or analogue configuration to a letter "B" , wherein the central region of the reentrance of "B" , indicated as "20" , is dimensioned and positioned in order to orient floss X expelling .

The effect of compression imposed to pole 20 occurs up to the moment that direction pulley 6 spins the enough so that the referred pole 20 reaches the cut 11 of it , moment that occurs an abrupt liberation movement of pole 20 that removes the end of floss X that is placed in the perimeter cavity 9 of direction pulley 6.

The abrupt movement of liberation of pole 20 , besides removing the end of floss X from its place in the perimeter cavity, makes such end of floss X to be expelled out of the opening 24 contemplated in the bottom face of the cover 3 and that is visible only in figures 1 and 7.

Figures 8 , 9 , 10 and 11 depict a variation of the said box, wherein its several parts are indicated by references preceded by letter V. The variation from figures 8 , 9 , 10 and 11 comprises an activation device that is formed by an activation lever Vl , by spring V2 from activation lever Vl , by transmission arm V3 and by lock device V4.

The device from the others locks comprises a blade support V4.1 , the mobile blade V.4.2 and spring V.4.3. Blade support V.4.1 is fixed on VC body of the box through a pivot axle V4.4. It is also important to point that the blade support V4.1 has a cut V4.5 that functions as a rail for blade V4.2 on its portion which is on the surface of pulley VP, such blade in order to use the cut as a rail

has in its body a pine V4.6.

As it happens with the main model indicated in figures 1 to 7 , in the variation from figures 8 , 9 , 10 and 11 , the operation of the present box occurs by means of activation lever Vl that is pushed down being such movement transmitted for lock device V4 through transmission arm V3.

In a given situation, blade V4.2 pushes pine VPl down from pulley, which ends up for making the pulley to spin . As floss is pulled, pulley VP continues spinning and pine VPl ends up executing a complete round returning to its point in which it is pushed down, but before arriving to this point pine VPl makes blade V4.2 to move through the cut V4.5 and such blade V4.2 movement is represented by arrow X in figure 8. Said blade V4.2 movement only occurs when pulley is being counterclockwise moved .

Being also part of activation device , it is located in pulley VP bottom face a metallic lock V4.7 , such lock functions to prevent pulley from spinning clockwise , and to do so, metallic lock V4.7 ends up touching a VCl wall that belong to body VC of the box when pulley VP is perhaps moved clockwise .

Another alternative designed and presented in the floss box for public places according to variation in figures 8 , 9 , 10 and 11 regards to enlargement of perimeter cavity existent in pulley VP . In the model indicated in the figures 1 to 7 such perimeter cavity that is referenced by indication 9 , has floss exact

width, however, perimeter cavity, contemplated in the variation indicated in figures 8 , 9 , 10 and 11 referenced by- indication V5 , belonging to pulley VP of the box herein mentioned it is necessarily wider than floss , that is , floss is not so narrowly stuck as it occurs in the main model mentioned in figures 1 to 7.

Another difference contemplated in the variation indicated in figures 8 , 9 , 10 and 11 , regards to a new configuration presented in the cut device , hereinafter referenced as V6.

The cut device referenced as

12 in the box model indicated in figures 1 to 7 aims to execute the cut in floss in an automatic manner and presents an alternative setting regarding to the existence of a longitudinal tail V6.1 inserted under cutting device itself that is better indicated through figure 9. Such tail V6.1 aims to set that the floss always enters in the cutting hole V6.2 , and it permits a larger facility during floss bobbin change, inasmuch, with such alternative , executor of floss bobbin change does not need to manually put the floss edge inside the said hole V6.2 , once the tail V6.1 makes this function in an automatic manner .

Last difference indicated in variation of figures 8 , 9 , 10 and 11 regards to increase of the opening of the cover bottom, such opening that is referenced as 24 in the main model indicated in figures 1 to 7. Note that it is by such opening the floss is expelled out of the box . For the variation described in figures 8 , 9 , 10

and 11 , the Holder designed a cover T with an opening referenced as V7 larger, more specifically, the opening V7 presented in the bottom of the cover VP has at least the size of the floss to be expelled . Thus , floss edge does not remain inside the box because it does not find any obstacle during its expelling.
