Figure 21 is an overview of a broadcast device.

Figure 1 shows a diffuser for dispensing a product in the sanitary water. This diffuser designated by 105 as a whole, has a first connector 101. It includes a second connector 102. It also comprises a gate 107 which allows the passage of water through orifices 108 and a needle 111. This device is configured to receive a removable cartridge 106, containing a water-soluble product.

The diffuser 105, using the connection 101 is connected to the valve 100 connected to the water network. This faucet can be a simple faucet hot or cold water, a mixing valve, a mixer or a thermostatic valve. The second connector 102 serves to connect a shower consisting of the flexible hose 103 and the showerhead 104.

The diffuser 105 is configured such that the water flow established between the first connector 101 and the second connector 102 enters the cartridge 106 to mix with the product contained by the cartridge 106, to diffuse it through the shower head 104. In FIG. 1 the tank body 109 is of oblong shape and the connectors 101, 102 are arranged at each end of the body 109.

For the user the implementation of the diffuser 105 is very simple. The user introduces into the chamber 110 of the body 109 of the reservoir a cartridge 106. The cartridge 106 is perforated by a needle 111 fixed in the body 109 or according to one of the methods described by way of example in FIGS. 3 and following. When the user opens the water tap, the cartridge 106 diffuses for a few minutes the product it contains. This product is diffused according to a predetermined dosage in time. The diffusion time may vary for example between 2 min and 8 min depending on the characteristics of the product of the cartridge 106, the effect desired by the manufacturer, the amount of product or the flow of water. The user can thus choose capsules for different uses, such as a shampoo at the beginning of the shower, or a shower gel and finish with a cosmetic product, or a coloring product, relaxing, a fragrance, a food flavor, etc. It can therefore change cartridge 106 single use, at will.

According to Figure 2, the body 109 of the reservoir comprises two parts, an upper portion 200 and a lower portion 201. It further comprises a cord 203 which is a more or less flexible connection between the two parts of the body 109. This cord 203 can also be obtained in an elastic material. This cord 203 is shown in Figure 2, external to the tank. However, it is possible to include this cord 203 in the chamber 110 of the reservoir, but also in the thickness of the wall 109. To insert a cartridge 106 in the chamber 110, the user separates the lower part

201 of the upper part 200. It can then insert and position the cartridge 106 in the chamber 110 of the body 109 of the tank. During the installation of the cartridge 106, the cord 203 retains the lower part 201 and facilitates the handling of the assembly. The cord 203 avoids in particular the fall of the lower part 201. Once the cartridge inserted, the user closes the body 109 of the tank. By assembling the lower part 201 with the upper part 200, the user re-establishes the tightness 105. It can then again use the shower, and benefit from the product in the cartridge.

In this figure the upper 200 and lower 201 parts are shown as two symmetrical parts of a tank 109 of oblong shape. According to an alternative, the body 109 of the tank comprises a fixed part and a removable hatch. The hatch is disposed on the fixed part and allows in the open position to insert the cartridge 106 in the chamber 110 of the body 109 of the tank. In the closed position, this hatch seals the body of the tank to allow the normal operation of the diffuser 105.

One of the characteristics of the invention is that the cartridge 106 containing the product to be diffused is sealed. It is therefore necessary to break the sealed barrier formed by the casing of the cartridge 106 to allow the diffusion of the product in the sanitary water. According to Figure 3 the body 109 of the reservoir further comprises one or more needle (s) 302 in the lower part 201 and one or more needle (s) 304 in the upper part 200 of the body 109 of the reservoir. The needles 302 are supported by a grid 301 present in the lower part 201. In the same way, the needle 304 is secured to a grid 303 and the upper part 200.

The grids 301, 303 serve to support the needles 302, 304, but they also serve to position the cartridge 106. The needles are used to pierce the cartridge 106, during the insertion thereof or when the body is closed. of the diffuser 105. Positioned on the side of the water inlet, the needle 304 allows water to enter the cartridge 106. Positioned on the other side of the cartridge 106, the needle 304 allows the mixture consisting of water and dissolve product out of the cartridge.

According to an alternative embodiment, the grid 301, respectively 303 can be replaced by simple connecting arms which connect the needles 302, respectively 304 to the lower part 201, respectively to the upper part 200 of the body 109.

Just as the number of needles 302, 304 in a diffuser can vary, different shapes can fulfill the function of perforating the cartridge 106. FIG. 4 illustrates an embodiment of a needle 400. This needle 400 in the shape of a peak comprises a rod 403 with an attachment end 405 and a head 407 comprising a sharp tip 404. From the tip 404 part a bulge 406, comprising two increasing parts 401 and decreasing 402.

The needle 400 is held in the body 109 of the diffuser 105 by its fixing end 405. Depending on the case, this fixing end joins the needle 400 for example with a grid, a junction arm or with the body 109 of the tank. By the pressure exerted on a cartridge 106, the tip 404 pierces the envelope of the cartridge 106 and penetrates the cartridge. The bulge 406 enlarged the perforation obtained. The increasing 401 and decreasing 402 portions are substantially symmetrical to facilitate the withdrawal of the needle 400, during the extraction of the cartridge 106. According to an alternative embodiment, the head is a round or oval protuberance, bevelled to allow maximum penetration of the cartridges.

The depth of penetration of the head 407 will be better understood with the study of FIGS. 5 and 6. FIG. 5 represents a cartridge whose envelope 501 in the perforation zone at least has a small thickness 502. The cartridge is perforated at using the needle 400, which produces an orifice 503. The small thickness 502 of the cartridge 106 relative to the length of the needle allows the head 407 of the needle 400 to penetrate completely into the cartridge 106 to clear the entire orifice 503, the importance of the clearance is identified by the reference 504. Figure 6 shows a cartridge whose casing 601 in the perforation zone at least has a large thickness 602. The orifice 603 The clearance is designated by the reference 604. Preferably the cartridge 501 having a smaller thickness 502 is used for a more viscous product, in order to obtain a better viscosity. e promote its flow. Conversely, the cartridge 601 having a higher shell thickness 602 is used for a more fluid product, in order to limit its flow. It is thus possible to control the diffusion of the product according to a predetermined dosage in time by an appropriate choice of the viscosity of the product, the thickness of the wall of the cartridge 106 and the geometry of the perforation means.

For example for a cartridge 106 whose envelope to a thickness of about 0.3 mm, comprising 10 ml of a product whose viscosity is similar to that of water, perforated by a 1 mm orifice, a cartridge was made 106 which empties for a duration varying from 30 sec. at 2 min. for a water flow rate of between 15 and 50 liters per minute.

According to another embodiment not shown, the needle has a funnel shape. She is hollow and sharp.

According to a first embodiment, the cartridge 106 is made in one piece, the thickness of the envelope of this cartridge 106 being adapted to the product contained by the cartridge 106. In this configuration the thickness of the envelope can be thinner in the perforation areas compared to the rest of the envelope. This allows both to facilitate the drilling and to ensure the relative rigidity of the cartridge 106 to ensure its resistance against the pressure exerted by the needles and allow the operation of the diffuser 105.

The concept of relative rigidity in this text means that under the pressure of the needles in the areas provided for perforation, the capsule should not deform so that the deformation prevents perforation by the needles. This corresponds to the threshold of acceptable deformation of the cartridge beyond which the perforation is no longer systematically obtained.

The product contained in the cartridge 106 can be a liquid, a gel, a powder or a soluble solid product, alone or in combination. The cartridge 106 can be obtained according to various alternative embodiments. It may be formed of one or more parts may have orifices to allow such filling.

FIG. 7 represents a view of a cartridge 106. The cartridge 106 comprises a body 700 ensuring a rigidity relative to the cartridge 106. The body 700 has the shape of a symmetrical egg so that it can be inserted into the diffuser 105 in the both directions. The body 700 comprises holes in the perforation zones 704. These holes are hermetically sealed by covers 701, 702. The covers 701, 702 seal the cartridge 106. Similarly, the relative stiffness of the cartridge 106 ensures that the body 700 of the cartridge 106 does not deform with the pressure of the needles on the covers. The material used to make the covers 701, 702, may be identical or different from that used for the body 700. The material may for example be plastic, paper, or a soluble material whose dissolution is controlled.

FIG. 8 represents a view of a cartridge 106 according to an embodiment similar to the previous one which differs in the perforation zones 804 by the presence of an alternating reinforcing structure 801 with one or more holes 802. This reinforcement structure 801 serves to support the lid 803. It allows the geometry of the lid 803 to be maintained under the effect of the pressure of the needles 111. The hole or holes 802 are arranged opposite the perforating means of the The holes 802 on the one hand perforation, on the other hand the entry of water or the flow of water mixed with the product contained in the tank. The reinforcement structure 801 is in one piece with the body 800 of the reservoir. In this embodiment, the body 800 also comprises an attached reinforcement structure 806. This added reinforcement structure 806 is made of a material identical to or different from the body 800. It comprises orifices 805. The assembly 806, 805 has the same function as structure 801 and holes 802.

With reference to FIG. 9, another embodiment of a sealed cartridge 900 which is intended to be perforated by the user before insertion into the diffuser 105 is now described. In this embodiment, the cartridge 900 comprises 901 covers. It also comprises one or more plugs 902. This plug 902 comprises a peak 903. With the aid of this peak 903, the user perforates the caps 901. The peak 903 is configured to obtain a perforation orifice. whose predefined size has been designed according to the viscosity of the product contained by the cartridge 900.

The cartridge 106 may be of one or more sealed materials, for example rigid or flexible plastic, waterproof paper or any other suitable waterproof material that may be soluble.

Referring to Figures 10-14, various embodiments of a delivery device containing additional features will now be described. Figure 10 shows a diffuser 105 whose body 120 of the reservoir is in two asymmetrical parts. The body 120 comprises a plate 121, perforated by perforations 122 from one side, on which is disposed a punch 123. The body 120 further comprises fins 124. The plate 121 supports the cartridge 106, which has been positioned in the cavity 125 by the fins 124. These fins may be perforated to facilitate the flow of water flow. The punch 123 pierces the cartridge 106 during the insertion of the cartridge 106 or the closure of the body 120.

Finally, the size of the lower right portion is greater than that of the upper portion, to facilitate the maintenance of the cartridge 106 during the introduction and extraction manipulations by the user. FIG. 11 represents a mode of cooperation between the upper part 140 and the lower part 141 of the tank body. In this mode, the lower portion 141 enters the upper portion 140. Each portion includes a bevel 142, 143, to facilitate guiding when nesting one into the other. The user then applies a longitudinal movement to achieve this insertion. The adjustment between the two parts is sufficiently tight to satisfy the mechanical maintenance of the system, while allowing the opening of the body by hand. The tightness of the tank body is satisfied by a sealing means such as a seal (not shown).

Figure 12 shows an embodiment of the diffuser, in which the upper 160 and lower 161 parts have an identical length 162, 163 identical. In this embodiment the assembly of the two parts is made by rotation, using a screwing. In addition, the upper portion 160 includes a control 164 and the lower portion 161 comprises a control 165. These indicators are intended to help the user to visualize the alignment of the two parts. The user must present the indicator 165 of the lower part 161 of the body, opposite the indicator 164 of the upper part 160, in order to be able to exert a rotational movement which assembles the two parts and hermetically closes the body of the body. 105. The rotational assembly exerts a force between the upper portion 160 and the valve (not shown) via the nut 166. This effort could weaken the device and eventually break it. To reduce this risk, this embodiment provides a stress zone 167. This stress zone 167 is responsible for absorbing the forces due to the repeated opening and closing of the device. This zone is flexible enough to twist slightly and rigid enough not to hinder the rotation related to the opening and closing of the diffuser 105.

In this embodiment, the use of an assembly by rotation of the two parts involves the realization of a body comprising on the axis of rotation at each end, a single needle to simply pierce the casing of the cartridge 106. Otherwise, if multiple needles are used at one or both ends, either the envelope of the cartridge is torn, or there is a break of the needles which are not positioned on the axis of rotation. According to an alternative embodiment, the force zone is replaced by a flexible sleeve between the nut 166 and the zone 167 of the upper part 160. In case, the zone 167 is no longer a force zone. It has the same mechanical characteristics as the rest of the tank body. Figure 13 schematically shows a diffuser in two asymmetrical parts. The body of the diffuser has a straight zone of total length 182. The lower portion 181 has a right zone of length 183. The lower portion 181 further comprises a lug 184, the upper portion 180 comprises a notch 185. The lug and the notch are capable of cooperating and allow to help the user to align the two parts of the body before performing the rotational movement ensuring assembly of the two parts, by locking a bayonet.

The length 183 is greater than half of the total straight length 182. The length 183 may for example represent about 2/3 of the total straight length 182. This arrangement facilitates the manipulation of the user. Indeed, it then literally deposits the cartridge 106 in the lower portion 181 which has a gaping hole with a high edge, preventing the cartridge 106 from falling and keeping it in place. The lower portion 181 of the diffuser 105 which accommodates the cartridge 106 inside the diffuser 105 then has straight peripheral edges and not egg-shaped that allow the insertion of the widest part of the cartridge.

Referring to Figure 14, will now be described a diffuser for inserting a cartridge without changing the setting of the water temperature on the faucet of the sanitary installation. This diffuser 350 comprises a valve 351 and a non-return valve 355.

The valve 351 is located between the body of the diffuser 350 and the connector 354. The connector 354 is the one connected to the valve 360. The valve 351 comprises in particular a body 352 and a selector 353. The selector 353 under the action of the User moves in the body 352 of the valve 351. According to the open or closed position of the selector 353 defined by the user, the flow of water from the valve 354 is stopped or not.

The check valve 355 is positioned between the second connector 359 connected to the shower hose 361. It is a ball valve 356, comprising a seat 357 and a spring 358. Under the effect of the pressure of the running water when the water valve is open, the valve 355 opens and lets pass the water from the diffuser to the hose. When the flow of running water is interrupted, the valve 355 closes, the ball 356 under the pressure of the spring 358 seals against the seat 357. The valve 355 thus prevents the water contained in the hose to escape through the diffuser 105 when it is open to insert a cartridge.

FIG. 18 represents a diffuser designated by 220 as a whole, comprising a fixed part 221 and a removable part 222. The fixed part 221 comprises a T referenced 225, a grid 226, a hollow tip 227. The removable portion 222 comprises a circular guide 231, and fins 232.

The T 225 is disposed at one of the two ends of the fixed portion 221. This T 225 is connected by a connection 229 on the one hand to a water inlet 100 and on the other hand by a connection 230 to a departure to a diffusion device such as a spa or shower. The T 225 further comprises a not shown valve allowing the user to isolate the diffuser chamber and obtain a direct flow path of the water. At the end of the fixed portion 221 where the T 225 is located is arranged the gate 226 which serves as a support for the hollow point 227. This hollow point 227 is intended to perforate the cartridge 106. This hollow point 227 in the form of a tubing which allows the circulation of fluid within it. This tubing is pointed at one end and perforated by holes 228 to allow flow.

At the other end, the fixed portion 221 has an opening 233 through which a portion of the cartridge 106 enters the diffuser chamber. At this same end, the fixed portion 221 comprises a male thread 223. This thread is intended to cooperate with the female thread 224 of the removable portion 222 to allow the closure of the diffuser reservoir 220.

The removable portion 222 comprises an opening 234 for the insertion or extraction symbolized by the arrow 235, a cartridge 106 in the removable portion 222. The insertion of a cartridge 106 is guided by a circular guide 231. This circular guide 231 is disposed in the removable portion 222 to be at the equator of the cartridge 106. Thus it guides the portion corresponding to the highest diameter of the cartridge 106. To complete the positioning of the cartridge 106 in the part removable 222, the removable portion 222 has the end opposite the opening of a plurality of fins 232.

According to an alternative embodiment, the removable portion 222 does not include additional positioning means but an end whose shape is defined to ensure this positioning.

In operation, the user inserts a cartridge 106 in the removable part 222. Then, with reference to FIG. 19, the user screws the removable part 222 on the fixed part 221. During the closing of the reservoir, the tip 227 pierces the cartridge 106 to penetrate more or less depending on the size of the cartridge 106. Closing the tank restores the seal of the tank with a seal. In addition, the removable portion 222 comprises a recess zone 236 adapted to receive and cooperate with a lever 237. This lever 237 actuates a stop valve 238 to stop the water supply when the removable portion 222 is removed and restore the circuit when the body of the diffuser is closed. This valve prevents the user from interrupting the water whose temperature he has set and who arrives at his shower during the insertion operation of a cartridge 106. After the insertion of a cartridge and the opening of the water circuit by the user, the water enters the diffuser 220 through the connector 229, the T 235, the chamber 239, the tip 227 and the cartridge 106 The inner shape of the fixed part 221 of the diffuser 220, in particular in the part of the T 225, creates a venturi effect, through which the water entering the diffuser, mixed with the product contained in the cartridge 106, leaves the diffuser to be evacuated. through the connection 230.

According to an alternative embodiment not shown, the water flow is oriented at the T 225 by an adjustable flap. This flap condemns the direct path between the inlet corresponding to the connection 229 and the outlet corresponding to the connection 230, to force the water to pass into the chamber 239 and mix with the product of the cartridge 106, before emerging. In this case the part of the T serving as a junction with the body of the fixed part 222 comprises a partition for separating the incoming water flow from the outgoing water flow. When the diffuser is not in use or open, the shutter makes it possible to restore the direct path of the water and insulates the chamber hermetically. The flap then replaces the flap described in Figure 18.

Fig. 20 shows an alternative embodiment of the mode described in Figs. 18 and 19. In this mode, the diffuser 260 comprises a fixed portion 261 with a T 263 and a cartridge. As in the previous version, the fixed part comprises a grid 266 which serves to support a plurality of needles 265 intended to break the seal of the capsule by perforation. This embodiment differs from the previous one, in particular by the sealed cartridge 262, whose wall 267 is adapted to cooperate with the fixed part 261 to form a sealed tank. The cap 264 is arranged to be inside the sealed reservoir thus formed. The lid 264 is also facing the needles 265 to be perforated by them, to allow mixing of the water with the product contained in the cartridge 262.

FIG. 15 represents a cartridge 650, comprising a lid 651, serving to close the orifice of this cartridge 650. The lid 651 is precut. The precut 653 corresponds to an area where the junction between the cartridge 650 and the lid 651 is weakened to promote the opening of the cartridge 650. To vary the size of the orifice through which product flows contained in the cartridge, simply adjust the position of the precut 653. This allows to adapt the surface of the lid 651 and the corresponding orifice depending on the viscosity of the product to be put in the cartridge 650. The precut 653 is partial . A portion 652 of the cartridge 650 is not pre-cut so that the lid 651 once depressed remains integral with the rest of the cartridge. Thus the cover will not plug the hole obtained on the cartridge 650. This operculum 651 will not clog the devices connected to the diffuser, such as the shower head. FIG. 16 shows a cartridge 655 whose pre-cut 656 defines a cap surface greater than that of FIG. 15. This cartridge 655 is intended to be used with products whose viscosity is greater than that used for FIG. FIG. 17 shows a cartridge 660 whose orifice closed by a stopper 662 with a pre-cut contour is driven by a lug 661 projecting into the reservoir but not cutting, such as a finger with the rounded end which just pushes on this plug until at the rupture of the plug clogging the orifice. To allow easier driving, the area of the plug 662 can be flat or concave.

According to another alternative, the orifice is clogged with a seal that is soluble in water. In this case, there is no longer any need for piercing means.

In the embodiments mentioned above, it is possible by adjusting the size of the orifice to manage the flow times according to the different product viscosities. In the case of a rigid cartridge, the internal space of the cartridge keeps the same volume while the cartridge empties. Water can take the place of the product that has been broadcast.

In other embodiments, the cartridge may be in a flexible material that crushes as the cartridge empties, so that little or no water enters the cartridge. In this case, it is the pressure of the flow of water on the flexible wall which tends to cause the product to come out of the cartridge by the perforation or perforations.

According to an alternative mode of use, the diffuser can be installed on other sanitary equipment such as the supply lines of a spa, or the kitchen sink faucet, in order to diffuse a soluble disinfectant in water or a degreasing product.

In the examples above, the diffuser is installed near a tap. Other arrangements are possible. Figure 21 shows a diffuser 105 for dispensing a product in the sanitary water. This diffuser receives water through a pipe 119, pipe connected to a valve 100. The pipe 119 may be rigid or flexible. The diffuser 105 is also connected by means of a flexible hose 103 to a showerhead 104. Although the invention has been described in connection with several particular embodiments, it is quite obvious that it does not It is in no way limited and includes all the technical equivalents of the means described and their combinations if they fall within the scope of the invention.

The use of the verb "to include", "to understand" or "to include" and its conjugated forms does not exclude the presence of other elements or steps other than those set out in a claim. The use of the indefinite article "a" or "an" for an element or a step does not exclude, unless otherwise stated, the presence of a plurality of such elements or steps. Several means or modules can be represented by the same hardware element. In the claims, any reference sign in parentheses can not be interpreted as a limitation of the claim.
