Description

DISPERSION SYSTEMS

The invention relates to obtaining container-type containers in a container, in particular of some multicamera.

The invention also relates to the realization of preforms necessary for obtaining container-type containers in a container.

The invention also relates to the elaboration of processes necessary for obtaining container-type containers in a container.

The invention also aims to produce multifluid atomizers - atomizers capable of dispersing twice as many fluids simultaneously.

The invention also relates to the realization of dispersing systems consisting of container-type containers in a multicamera container and of multifluid atomizers.

Conventional container-to-container (IRR) type containers are usually multilayer structures (composites / laminates), made of two components with different roles: a relatively rigid main container - arranged on the outside - ensures the structural strength of the assembly; a structurally flexible secondary container - arranged inside - constitutes the liquid storage compartment. Systems of this nature are set forth in: US20160185505A1; W02014017910A2; W02009088285A1. As the liquid in an RIR container of this type is consumed, the internal container gradually detaches from the external one, compressing. Usually, the final shape of the internal container - after depletion of the liquid contained and completion of compression - is unpredictable, random.

Another type of conventional RIR container consists of a high rigidity outer vessel and a relatively rigid structural inner vessel. A system of this nature, with a number of variants, is set forth in US20130193164A1. During use, the walls of said structurally relatively rigid inner container undergo a controlled process of collapse. These walls are compressed in an orderly manner, using certain 'surface features' (three-dimensional geometric shapes) inserted into their structure.

Conventional RIR containers can provide airless bottling - without contact between the product contained and the atmospheric air - and can also facilitate the operation of 360-degree dispersion systems without the need for additional specialized components.

With some exceptions, however, the RIR containers indicated above are functionally limited in that they are not multicameral, so they cannot store and disperse multiple fluids simultaneously.

Exceptions include a system presented in WO2009088285A1, a document already cited. It proposes as a solution to make a multicameral RIR container the use - complementary to the outer container, more rigid - of two flexible inner containers, one inserted inside the other. One of the inner receptacles - the one most centrally arranged in the IRR receptacle - is practically located inside the liquid contained by the other inner receptacle. The resulting storage compartments are not symmetrical; the use of such a technical solution may make it difficult to extract liquids from storage compartments.

Conventional multi-chamber containers - on the other hand - are also of several types. Integral multicameral containers consist of a single container, compartmentalized by means of rigid or semi-rigid walls; the walls are made jointly - integrally - with the body of the container. Such systems are disclosed in US5482170; US20120241474A1. Another type is combined containers. They are generally made of twice as many containers, assembled in a certain shape; for example, in USD809404S the assembly is done using a plastic sheet.

Conventional multi-chamber containers have - compared to RIR-type containers - a number of disadvantages: the difficulty of ensuring, in the absence of additional components, both airless capacities and the 360-degree use of dispersing systems.

The present invention aims to obtain multicameral type containers from the category container in container (RIR), equipped with individual and independent storage compartments, possibly compartments of equal size and made symmetrically inside the RIR container.

Relevant spray-type dispersing devices in relation to the present invention are atomizers equipped with a manually operated pumping mechanism. Some models are made entirely of plastic, including the return spring. At least one device - detailed in US20060054642A1 and developed including commercially - has a return spring made of acetal / polyacetal plastics. Some atomizers have a return spring made of other categories of plastics - for example the one detailed in US6378739B1. Many other systems have a metal return spring.

Relevant in relation to the present invention are also the atomizers equipped with valves which have the precompression function. An example is US6378739B1 (document already cited), as well as US20140014691A1.

and 2018 00505

07/04/2018

On the other hand, atomizers capable of dispersing several fluids simultaneously are shown for example in US20170157632A1; US20030201342A1.

Some of the above-mentioned dispersing devices have among their disadvantages the large number of components, as well as the use of metals for the production of some of these components.

The present invention aims to obtain - in addition to the R1R type containers already indicated by multifluid manual atomizers, made of a small number of components and exclusively of plastics.

The main variant of the invention aims at obtaining a dispersing system equipped with a multicameral container-to-container (IRR) type container.

According to the main embodiment of the invention, an RIR container is produced by the process of integral blow molding to which a set of three preforms is subjected (integral blow molding means in the meaning of the present invention the simultaneous, unitary transformation of the components of the preform set). The resulting RIR container is of multilayer type, being composed of three constituent units - one external, one intermediate and one internal - which together form a laminated / composite structure.

According to the main embodiment of the invention, the production of a multicameral RIR container involves the transformation / reconfiguration of certain regions of the external structure of a multilayer RIR container, reconfiguration by which the following are obtained inside the container:

two side liquid storage compartments a compression system of the side storage compartments.

The reconfiguration process involves:

exfoliation and

- the movement of the side walls of the (i) internal and (ii) intermediate units of the multilayer RIR container, processes which are preferably carried out in a controlled manner.

Exfoliation requires the removal of certain interfaces (adhesive contact surfaces) from the external multilayer structure of the RIR container. Unlike US20160185505A1 (document already cited) which aims at optimal ways of making and subsequently eliminating interfaces as a whole, the present invention aims at suppressing interfaces - at least in the case of the main variant - mainly at the side walls of the RIR container.

and 2018 00505

07/04/2018

Residual interfaces - interfaces that are maintained within the external multilayer structure - may be part of a clamping system between the constituent units of the R1R container. The clamping system is preferably practiced in the vicinity of the median on the longitudinal axis - preferably on the entire height of the RIR container, including the base.

The exfoliated lateral surfaces of the internal and intermediate units become internal mobile sectors; the configuration / operation of the RIR container involves the movement, preferably controlled, of these mobile sectors.

According to the main embodiment of the invention, the configuration of the side storage compartments can be a dynamic, short process, which can be carried out:

during the liquid bottling step in the RIR container, using even the bottled liquids:

the pressurized liquids are effectively introduced inside the multilayer external structure, in the lateral areas of the RIR container, between the walls of the intermediate and internal units; the pressurized liquids cause, in the respective lateral areas of the RIR container, the suppression of the interface between the intermediate and internal units. - on both sides - are relocated, under the pressure of the introduced liquids, in the region of the median on the longitudinal axis of the multilayer container; those relocated mobile sectors form a double-wall partitioning system

- simultaneously with the configuration of the partitioning system, two independent side storage compartments are also dynamically developed; both compartments are obtained between the side walls of the same two units: the intermediate and the internal;

the resulting bottling may be airless;

prior to the liquid bottling step, using another fluid (eg compressed air), mechanical means or a hybrid method; the configuration steps may be similar to those described above.

In order to allow the dispersion system to operate at 360 degrees, without the use of additional specialized components, the volume of the storage compartments must be gradually reduced - during the cycle of use of the dispersor system - in proportion to the consumption of stored liquids. In this respect, the mobile sectors derived from the intermediate unit have the function of compression system of the respective storage compartments.

and 2018 00505

07/04/2018

The compression system - in contrast to the fast configuration of the partitioning system - manifests a progressive, slow operation throughout the entire cycle of use of the disperser system. Thus, in proportion to the consumption of liquids:

- the side walls of the intermediate unit gradually detach from those of the external unit the resulting internal mobile sectors - on both sides - move, as a result of balancing the internal pressure of the RIR container, from the area of the outer walls to the median on the longitudinal axis. Internal mobile sectors determine the compression of the side storage compartments, reducing their volume.

The mobile sectors of the intermediate unit therefore constitute both the walls of the storage compartments (those outside the container) and, as a result of the movement to which they are subjected, the compression surfaces of those compartments.

According to the main embodiment of the invention, the balancing of the internal pressure of the RIR container is performed - similar to conventional RIR containers - with the help of atmospheric air. Proportional to the consumption of liquids, the air reaches between the walls of the outdoor unit and those of the compression system (mobile sectors of the intermediate unit).

For the control of the air flow, certain suitable elements can be provided at the upper end of the RIR container, in the opening area; the incorporation of those elements can be done from the manufacturing stage of the preforms necessary to obtain the RIR container.

To facilitate the reconfiguration of the external multilayer structure of the RIR container, that structure may be divided into regions with a distinct functional role, for example:

the area in the vicinity of the median in the longitudinal direction - arranged on (almost) the entire height of the RIR container - can be dedicated to a clamping system the lateral areas of the RIR container generate, by exfoliation, the main part of the internal mobile sectors certain intermediate regions - arranged between said areas previously - they produce, also by exfoliation, the peripheral sections of the internal mobile sectors, etc ..

Regions with a distinct functional role can be delimited by means of functional role design features - for example some three-dimensional geometric elements.

and 2018 00505

07/04/2018

According to the main embodiment of the present invention, the constituent units of the RIR container are preferable to have, structurally, different properties, able to correspond to the functional needs of each one.

The walls of the outdoor unit should preferably have a thickness and strength high enough to ensure the structural strength of the whole assembly.

The walls of the intermediate unit are preferably limited in thickness and strength. The operation of the compression system - practically an effect of the process of balancing the internal pressure in the RIR container - takes place during the cycle of use of the dispersor system, when the available energy is limited.

The walls of the indoor unit should preferably have a sufficiently high thickness and strength to ensure the necessary structural strength for the partitioning system. The configuration of this system takes place on the production / bottling line; there is therefore sufficient energy available to exfoliate and move / configure the respective mobile sectors. Unlike US20130193164A1 (document already cited) - which has constructional variants having a relatively rigid structural inner container - the inner unit of the RIR container made according to the main embodiment of the present invention is not used for the actual storage of liquids, but is transformed into a partitioning system; the transformation process takes place before the use cycle of the disperser system.

In order to facilitate the exfoliation and the configuration / operation, possibly controlled, of the mobile sectors of the RIR container, its external multilayer structure may also incorporate:

design features capable of performing a functional role; the design features may be both general and - possibly - specific, in particular a clamping system which may incorporate, in addition to the residual interfaces indicated above, a permanent joint between the units of the RIR container a certain degree of structural resilience in the indoor unit a certain degree of structural resilience - possibly a marginal one - at the level of the intermediate unit

- an adequate degree of adhesiveness at the interfaces between the walls of the constituent units.

Regarding the design features with a functional role integrated in the surface of an RIR container: one and the same design feature can assist the exfoliation and configuration of several corresponding mobile sectors (several layers) of the multilayer structure of 2018 00505

04/07/2018 container, even some with different structural properties. By contrast, the 'surface characteristics' embedded in some of the related containers US20130193164A1 are dedicated to a process of controlled collapse of the relatively rigid structural inner container.

According to the main embodiment of the present invention, after exfoliation, the movement of the mobile sectors during the configuration / operation process is conditioned - controlled - by a series of other elements:

lack of free edges; the edges of the mobile sectors are further connected to the laminated structure of the container R1R, by means of a clamping system a particular perimeter geometry of the mobile sectors - geometry derived mainly from the contour / shape of the clamping system previously indicated the lateral depth of the container R1R; the geometry of the side walls of the R1R container generates a corresponding profile for the internal mobile sectors, profd which - further - influences the position and even the final shape of these mobile sectors.

The elements, characteristics and conditionings set out above may have the effect - during the configuration / operation process - of the nonlinear movement, possibly through a flip-flop or multistable behavior, of the mobile sectors that have structural resilience. For example, non-linear operation may involve, in the first phase of travel, the development of a process of compression of the structure, and subsequently, after exceeding a tipping point, one of relaxation.

An advantage of the nonlinear behavior - especially bistable or multistable - is its reproducibility, its repeatability in structures made similarly, consequently, the mobile sectors of mass-produced R1R containers have the potential to be operated in a controlled manner.

The potential of the controlled operation justifies - at least in the case of certain RIR type vessels - the classification of the mobile sectors in the category of mechanisms.

According to the main embodiment of the invention, an atomizer equipped with a manually operated pumping mechanism is coupled to a multicameral RIR container of the type set forth above. The atomizer is capable of spraying two fluids simultaneously.

The return spring of the atomizer can be made of acetal / polyacetal plastics; the spring can be attached to the main body of the dispersing device by means of a console made uniformly with said main body. A pre-compression valve system can control the flow of fluid inside the atomizer.

A sealing assembly ensures the tightness of closing the RJR container; the sealing assembly may have two closure elements which may have an elongated, petaloid bottom.

The dispersion systems made according to the invention, consisting of multicameral RJR containers and atomizers capable of despairing several fluids simultaneously, can have airless capabilities and can be used at 360 degrees without the need for specialized additional components.

With regard to substances which can be stored and dispersed by means of a dispersing system made according to the invention, the description refers in particular to liquids. However, the invention can be applicable - mainly related to R1R containers - to other types of materials with low molecular cohesion (various types of fluids, powders, granules, viscous substances, etc.).

According to the invention, the term "duty cycle" means the period from the first operation of a dispersing system to the depletion of stored liquids.

According to the invention, the term "operation" has a broader meaning than the simple operation of the dispersing system. The term can also be used in relation to the actuation or movement of components, parts or surfaces of R1R containers, both during the use cycle and in previous stages (during the configuration of storage compartments, in the stage of bottling liquids, etc. .).

The above operation may also involve the "controlled movement" of certain surfaces; in addition to the actual movement or movement of a surface or part of it from one position to another, "controlled movement" may involve other processes: flexion, relaxation, compression, folding, curling, etc.

In the description of the invention, the transformation of a preform or a set of preforms into a container - a process which requires reheating, stretching and subsequently blowing into the final shape will be called blow molding.

Fig. 1 illustrates in perspective a dispersing system 100 - made according to the main embodiment of the invention - comprising a container-type container (hereinafter referred to as RIR container) 300 and a multifluid atomizer 500; the multifluid atomizer 500 is coupled to the container RIR 300.

Detail of RIR type containers

The next section details a set of preforms.

The RIR 300 container is obtained from a set of preforms 200 (fig. 2), following an integral blow molding process (all components of the preform set are subjected simultaneously to the unitary blow molding process).

According to the main variant of the invention, the set of preforms 200 is constituted in turn by assembling the component preforms: 220 (external), 240 (intermediate) and 260 (internal) - fig. 2, fig. 3a - 3c.

in the geometry of the component preforms 220, 240 and 260 a series of vertical segments with specific roles can be identified. The upper segments 221, 241 and 261 may incorporate 9 of 2018 00505

07/04/2018

- from the stage of making the preforms 220, 240 and 260 respectively - a series of functional elements necessary in at least one of the subsequent stages: blow molding of the RIR 300 container, its configuration, bottling of liquids, assembly and / or use of the dispersing system 100. Examples of such functional elements are the flange 229 and the stiffening elements 230 (fig. 2). The identification of other functional elements present at the level of the upper segments 221, 241 and 261 will be performed as the manner of realization and operation of the dispersor system 100 is detailed.

The upper segments 221, 241 and 261, respectively, are non-transformable during the blow molding process. As a result, after assembling the preform set 200 (not fully illustrated assembled), the geometry of the upper part of said preform set 200

- the part incorporating the segments 221, 241, respectively 261 - is identical to that of the upper segment 301 of the RIR container 300 (fig. 4a).

Intermediate segments 222, 242 and 262 - belonging to the component preforms 220, 240 and 260 respectively - are transition segments and tolerate certain shape transformations during the blowing process', the functional elements possibly integrated in the structure of these segments may suffer equally. some transformations of form.

The lower segments 223, 243 and 263 of the component preforms 220, 240 and 260, respectively, allow ample shape transformations during the blow molding process.

The set of preforms 200 - and the component preforms - can be made of any category of materials suitable for the purpose for which it is used, for example plastics; a combination of materials can also be used.

Component preforms 220, 240 and 260 can be manufactured individually by injection molding or by alternative methods - for example 3D printing. Component preforms

- all or only one part - can also be made as a unitary structure, obtained, for example, by injection (simultaneous or successive) of sandwich type or using other methods - for example 3D printing.

The geometry of the component preforms 220, 240 and 260 may differ from the circular shape illustrated in the drawings relating to the description of the invention.

The general profile of the circumference of each preform may differ - vertically - from one region to another.

The general geometry may differ from one preform to another.

The following section summarizes a series of elements and procedures related to the configuration and operation of the RIR 300 container made according to the main variant.

and 2018 00505

07/04/2018

As a result of the transformation of the preform set 200 into the RIR 300 container (fig. 1) - following the blow molding process - the component preforms of the preform set 200 (220, external; 240, intermediate; 260, internal) become units of the container. RIR 300 (320, external; 340, intermediate; 360, internal).

Fig. 4a-4b illustrate the upper segment 301 of an RIR container 300.

According to the main embodiment of the invention, the side compartments 310 for storing liquids are obtained between the side walls of the units 340 (intermediate) and 360 (internal) of the container RIR 300.

The compartmentalization process can start at the level of the upper segment 301, by moving the petaloid protrusions 264 (fig. 4a) - which constitutes the upper extremity of the internal unit 360 - towards the longitudinal median M; the grooves 265 can facilitate the controlled folding of the respective upper areas of the unit 360. Two incipient side compartments 310 are created in this way (fig. 4b); below the level of the upper segment 301, the surfaces of the units 360 and 340 are still joined.

The complete, effective configuration of the storage compartments 310 is preferably performed dynamically, simultaneously with the bottling of the liquids.

Fig. 6a - 6b and fig. 7 schematically illustrates, in the horizontal section itself, the lower part 303 (fig. 1) of an RIR container 300.

The bottling process takes place in the two 310 incipient side compartments. The introduction of liquids under pressure causes, below the level of the upper segment 301, the suppression of the interfaces (exfoliation) between the side walls of the internal (360) and intermediate (340) units. As a result of the exfoliation, the side walls of the 360 internal unit become mobile sectors.

The mobile sectors derived from the indoor unit 360 are relocated, under the pressure of the bottled liquid, in the directions Al and A2 (fig. 6a), in the area of the longitudinal median M of the container RIR 300. After relocation, the respective mobile sectors form the partition system 361, with wall double. At the same time, between the partition system 361 (arranged longitudinally median) and the outer walls of the container RIR 300, two complete side compartments 310 are created, on the entire height of the respective container RIR 300. The bottling thus achieved can be of the airless type.

During the cycle of use of the dispersing system 100, as the liquids are consumed, the side walls of the intermediate unit 340 gradually become detached from those of the external unit 320. The resulting mobile sectors move progressively - also in the directions Al and A2 - towards the area of the longitudinal median M of the RIR container of 2018 00505

07/04/2018

300. The mobile sectors of the intermediate unit 340 become the compression system 341 (fig. 7); the action of this system is practically an effect of the internal pressure balancing process inside the R1R 300 container.

between the walls of the external unit 320 and those of the compression system 341 the free spaces 311 gradually develop (fig. 6b and fig. 7); those spaces are gradually occupied by an internal pressure balancing fluid of the container R1R 300 (atmospheric air).

As the clearances 311 develop, the corresponding side compartments 310 gradually decrease.

Fig. 6b illustrates the container R1R 300 at the end of the cycle of use, after depletion of the liquids contained.

Liquid depletion results in the disappearance of the side compartments 310; the walls of the compression system 341 are superimposed over those of the partition system 361; the only volumes present inside the RIR 300 container are, at this stage, the clearances 311.

Alternatively, incipient side compartments can also be obtained according to the manner of making the RIR 410 container (fig. 5). It has two side indentations 414 at the upper level of the indoor unit 413. The free spaces 415 are formed between the walls of the indentations 414 and those of the intermediate unit 412, from the stage of assembling the preform set. By widening the free spaces 415, the incipient side compartments are formed.

Alternatively, an RIR container (not shown) may combine the above two solutions. Alternatively, an RIR container (not shown) that does not have protrusions and / or indentations may be used.

The following section details a number of components and procedures for making a fastening system between at least two units of an RIR container.

The presence of a fastening system in an RIR container facilitates its operation, in particular of the mobile sectors. Some elements of the clamping system can be incorporated from the production phase of the preform set, others may derive from the blow molding process.

The clamping system can integrate elements with complementary roles, used for: permanent separation of storage compartments exact / symmetrical execution of storage compartments 2018 00505

04/07/2018 in the case of the RIR 300 container, the fastening system is preferable to be positioned in the middle area 304 (fig. 1), an area that may have, among others, the following characteristics:

is located in the region of the median M; practically, the median area 304 follows the longitudinal contour of the container RIR 300, except the opening at the top the total width of the median area 304 may vary from one region to another, as well as within the same region (frontal, posterior, base region) in certain regions (or sections of certain regions) - for example in the base area the projection of the median area 304 on the side axis Y may coincide with the projection of the entire RIR 300 container on the same axis; in other words, the middle area 304 can occupy the entire width of the RIR container 300; etc ..

The permanent separation of the side compartments 310 of the RIR container 300 is ensured by the permanent joint 382 (fig. 1); it is preferable to be present at least between units 340 (intermediate) and 360 (internal); the permanent joint 382 can be practiced between all three units of the RIR container 300, as illustrated in FIG. 6a 6b and FIG. 7.

the permanent joint 382 can be integrated from the manufacturing stage of the preform set 200 and it is preferable to be positioned on the median on the longitudinal axis X of the preform set. the permanent joint 382 can be obtained by various means - for example with adhesive and / or by welding.

The methods of joining plastic parts are known in the art, the present invention does not insist on them; however, areas where adhesive joints can be made are indicated; it can be deposited in the form of strips or lines. in fig. 2 and fig. 3a 3b are illustrated such lines or strips: 233, inside the component preform 220 (external); 246 and 247, on the outside, respectively inside the component preform 240 (intermediate); 266, on the outside of the component preform 260 (internal); In practice, it is not mandatory to make all the respective lines or bands.

In some cases, the permanent joint 382 can also be made uniformly with the components of the preform set (or with some of them) - for example, by manufacturing the preform set (or some components) by 3D printing, sandwich injection, etc.

As a result of the large shape transformations generated by the blow molding process to which the preform set 200 is subjected, the permanent joint 382 is unlikely to retain its initial position - that held at the preform set stage 200 - on the median on longitudinal axis X. Its final geometry can therefore suffer deviations, it can become sinuous of 2018 00505

04/07/2018 (as illustrated in Fig. 1); Fig. 7 indicates the alternative positions 482 and 483 in which the permanent joint 382 can reach.

consequently, the permanent joint 382 is unlikely to be able to ensure - only the precise configuration of the side compartments 310, compartments that are preferably symmetrical / equal.

However, the sinuosity of the permanent joint 382 may be irrelevant, if its general lateral profile - the total width of the sinuosity on the lateral axis Y - falls within the gauge (width) of the median area 304, along its entire height. In this case, the permanent joint 382 is covered - physically - by the other elements of the fastening system, elements also arranged in the middle area 304.

The following paragraphs detail the second category of components of the fastening system.

following the blow molding process through which the RIR 300 container is obtained, adhesive contact surfaces, interfaces are formed between the walls of the constituent units 320 and 340, respectively 340 and 360 thereof.

The initial interface 380 is formed between the external unit 320 and the intermediate unit 340 (fig. 6a); a similar initial interface (not shown) is formed between the intermediate unit 340 and the internal unit 360.

The configuration of the side compartments 310 and the subsequent operation of the RIR 300 container shall suppress the interfaces in certain regions and maintain them in other regions of that RIR 300 container.

The interfaces are suppressed in the side regions of the RIR 300 container, resulting in the appearance of the mobile sectors of units 340 (intermediate) and 360 (internal), indicated above.

Preferably, the interfaces are maintained in the middle area 304; these residual sections of the initial interfaces constitute the second category of components of the fastening system.

Residual sections 385 (Fig. 6b and Fig. 7) are remnants of the initial interface 380 (Fig. 6a) between units 320 and 340; as a whole, the residual interface 385 will be called.

Residual sections 386 (figs. 6a - 6b and fig. 7) are remnants of the initial interface between units 340 and 360 (not shown, as already shown); as a whole, the residual interface 386 will be called.

and 2018 00505

Due to their adhesive properties, the residual interfaces 385 and 386 maintain contact between the constituent units 320, 340 and 360 of the RIR container 300 in the middle area 304, preferably over the entire height of the container RIR 300, including the base.

The geometry of the two residual interfaces - 385 and 386 - can be identical; it can also coincide with the geometry of the median area 304. Residual interfaces may be present on the entire surface of the median area 304 - forming a continuous structure - or only in certain regions of it.

The final geometry of the residual interfaces 385 and 386 is determined by the manner of exfoliation of the mobile sectors of units 340 (intermediate) and 360 (internal). The degree of adhesiveness of the initial interfaces may also be a relevant factor in obtaining the final geometry of the residual interfaces.

The degree of adhesiveness of the initial interfaces can be controlled by several methods: the choice of the types of plastics from which the units of the RIR 300 container are made; the introduction of certain adhesives (or, conversely, of separating agents) into those plastics; depositing adhesives (or separating agents) between the component preforms of the preform set 200 (possibly only between certain preforms or only in certain regions between those preforms - for example inside the upper segment 301) etc ..

The degree of adhesiveness can vary both from one interface to another and within each interface, depending on the region.

consequently, having adhesive properties and having a final shape obtained in a controlled way - after the blow molding process - the residual interfaces 385 and 386 are able to contribute to the obtaining of symmetrical, equal storage compartments.

The two categories of components of the clamping system - the permanent joint 382, on the one hand, and the residual interfaces 385 and 386, on the other hand - overlap in the region of the middle zone 304 and offer each other margins of error in design and operation.

the permanent joint 382 may have a sinuous final contour - the effect of the blow molding process - but visually and functionally it is covered by the residual interfaces 385 and 386, which help in the precise configuration of the storage compartments.

In turn, the residual interfaces 385 and 386 can be accidentally suppressed during the cycle of use of the dispersing system 100 (for example by deforming the container), without affecting the operation of the system; a possible exfoliation is limited (blocked) by the permanent joint 382.

Using both categories of fasteners - residual interfaces and permanent joint - symmetrical, equal and permanently separate storage compartments can be obtained.

and 2018 00505

04/07/2018 37

Alternatively, the clamping system can be made using elements from a single category of those indicated above (permanent joint or residual interfaces). For example, the residual interfaces can be partially or totally suppressed from the stage of configuration of the side compartments, the only component of the fastening system being the permanent joint.

Such an alternative clamping system can be adopted - for example, but not exclusively - in the case of IRR containers made of opaque plastic, which does not provide visibility inside. The shape or ultimate position of the partitioning system is not, in such a container, really relevant; aesthetics is not affected. in such a case, storage compartments equal in volume are obtained simply by introducing an equal amount of liquid into each of the incipient storage compartments; compartmentalization may be assisted by other elements likely to produce the controlled movement of the mobile sectors.

Returning to the main embodiment of the invention, in order to increase the functional capacity of the clamping system, certain design features can be integrated in the structure of the RIR 300 container to reinforce the residual interfaces 385 and 386 - for example three-dimensional geometric elements or models; they are part of the broader category of functional design features that may be present in the external multilayer structure of an RIR container.

The following section details the design features, elements that can facilitate, among other things, the controlled configuration / operation of the mobile sectors.

a number of functional design features can be incorporated into the external structure of a multilayer RIR container; these can be, for example, elements and / or three-dimensional geometric patterns. The RIR container being of multilayer type (composite / laminate), the design characteristics with three-dimensional profile present on the surface of the external unit will have a correspondent in the structure of the other units; this constructive feature can facilitate the configuration / operation of the internal mobile sectors of the RIR container.

The design features can be used, for example, to delimit certain regions with a distinct functional role present in the external multilayer structure of the RIR container, to reinforce the interfaces indicated above, to facilitate the operation of the mobile sectors, etc.

Design features can be classified into two main categories: general design features - the category includes the profile (shape) and proportions of the RIR container, as well as other striking design features of 2018 00505

04/07/2018 specific design features - the category includes specific additional three-dimensional geometric elements and patterns, inserted in the surface of the RIR container.

In the following paragraphs, the design features of both categories will be detailed:

at the constructive level at the functional level

At the construction level, the design characteristics of both main categories - (i) general and (ii) specific - and the combinations between them, are defined in that:

may have simple, elementary or complex form (s) may interact:

can be intersected can be associated can be simple or elaborate models

- can be inserted in any region of an RIR container

- can be extended / continued from one region to another can be (i) cavity type and / or (ii) embossed (embossed) can have various three-dimensional profiles:

- the cavities of some may have a different depth than those adjacent to each other and the same cavity may have different depths of value from one area to another;

(Similar principles apply to embossed geometric elements).

Examples of general design features are the profile / shape of vertical segments

302 and 303 of the RIR 300 container (fig. 1); their shape can influence the functioning of the mobile sectors. Other examples of general design features are edges 390 and 394 (Fig. 1). They delimit / separate regions with distinct functional roles: the median area 304, dedicated to the fastening system; oblique faces 305, whose exfoliated inner sections represent the peripheral part of the movable sectors and whose sections are folded (overlapping), preferably controlled, over regions belonging to the median area 304; the side faces 306, the exfoliated inner surfaces of which form the main part of the movable sectors.

Another example of general design features is shown in FIG. 8, which illustrates an alternative container RIR 420, in the horizontal section itself made at the level of the main body (equivalent to the vertical segment 303 of the container RIR 300).

and 2018 00505

07/04/2018

The oblique walls 425 (alternatively can be made longitudinally) of the protrusions 424 can mark a limit (an obstacle) in exfoliating the side walls of the container RIR 420, by changing the angle of detachment of the surfaces of units 422 and 423 from the external multilayer structure.

The protrusions 424 represent the median area of the RIR container 420, the equivalent of the median area 304 within the container RIR 300. The protrusions 424 may be present in both the front and the rear of the container RIR 420; the base of the container can be adapted to also have a middle region with more pronounced design features.

Returning to the main embodiment of the invention, examples of specific design features are: the groups of point elements 395 and 396, inserted in the oblique faces 305, and the oval element 397, arranged on the side face 306.

Design features can be involved in several processes: exfoliation, bending, compression, unwinding, folding, corrugating the surfaces of mobile sectors, etc. Functionally, design features can be classified into two categories:

passive active

Passive-run design features are elements that (i) do not require or (ii) do not make use of resilience or the structural elasticity of the surfaces in which they are incorporated, within an IRR vessel, passive-run design features may, for example:

act as delimiting elements of the regions of the external multilayer structure, in some regions it reinforced the interfaces between the constituent units

- assist the plastic deformation of certain surfaces - including within the mobile sectors - on specific coordinates; they can thus facilitate the folding or curling (wrinkling) of certain sections; etc ..

Passive design features are - for example - the edges 390 and 394 (fig. 1), mentioned above.

Examples of passive design features with reinforcing role are the circular elements 391 and the linear elements 392 and 393, arranged on the surface of the median area 304 (fig. 1). The more marked the three-dimensional profile of these elements or geometric patterns, the more accentuated the reinforcement produced can be.

and 2018 00505

07/04/2018

The design features with active operation are assimilated functionally to the mechanisms. in the regions in which they are incorporated - as well as in the adjacent ones - they can actively determine the change of the shape and / or the way of moving the surface of the mobile sectors. Design features with active operation may, for example:

facilitates the flexion of surfaces on predetermined coordinates contributes to the stiffening - possibly with gradual manifestation - of specific sections of certain regions assist (or determine) compression / expansion of surfaces participates in the delimitation of regions with distinct functional role in the external multilayer structure of the R1R container; etc ..

Examples of active design features are the point elements of groups 395 and 396 (mentioned above) arranged on oblique faces 305 (Fig. 1); they can cause the flexion (curvature) of the surfaces on specific, predetermined coordinates.

depending on the geometry (shape) and layout, the active design features can cause - for example through a wavy behavior - the extension of the surface (of the imprint) of certain regions or, conversely, the reduction of the surface (imprint) of other regions; the ripple effect may be transient.

Similar to certain passive design features, some of the active type may also participate in the delimitation of regions with a distinct functional role in the external structure of the R1R container.

Making - obtaining - some of the design features may precede the blow molding step of the R1R 300 container: for example, the vertical grooves 265 (fig. 2, fig. 3c, fig. 4a) are made from the injection molding phase of the preform 260. Certain elements introduced in the blow molding phase can be made in the extension / completion of those already incorporated in the injection molding phase.

The few types of design features mentioned in the description - some illustrated - are set forth by way of example only and do not in any way limit the area of protection claimed by the present invention.

The following section presents specific / particular ways of creating and using the mobile sectors.

The internal and intermediate constituent units of a multilayer IRR container are preferable to have, at a structural level, an adequate degree of resilience / flexibility - even a marginal one in the case of the intermediate unit, the one from which the compression system is derived. After exfoliation, the mobile sectors are therefore preferable to be able to flex, to deform elastically.

and 2018 00505

07/04/2018

Using the structural residence of the mobile sectors, the operation of certain design features with a functional role incorporated in their surface may present a non-linear behavior, possibly of bistable or multistable type; as an effect, the mobile sectors themselves that accommodate design features with such particularities may have, at least partially / regionally, a non-linear operation, possibly of bistable / multistable type.

An advantage of the presence in the RIR containers of some mobile sectors with non-linear operation is the reproducibility, the repeatability of this type of behavior, especially of the bistable / multistable one. By obtaining such behavior, there are the premises for achieving a controlled, repeatable operation of the mobile sectors related to RIR containers mass-produced. Controlled operation according to the present invention allows variations in the overall operation of the mobile sectors - from one RIR container to another - if the variations, in turn, have a certain degree of repeatability within a series of RIR containers.

The potential of controlled operation requires the inclusion of certain mobile sectors in the category of mechanisms.

The specific way of realization and operation - the ability to transmit, through elastic deformation, movement and energy from one region to another of its own structure - justifies the inclusion of some of the mobile sectors in the category of compliant mechanisms.

Also, the realization in the form of a continuous structure, in combination with the way of controlled change of profile / shape during the movement from the initial position to the final one, recommends the inclusion of some of the mobile sectors in the category of morphing surfaces (surfaces capable of adaptive transformation). . The classification is especially valid in the case of mobile sectors with slow configuration / operation (in the case of the RIR 300 container, the walls of the compression system 341), if they are structurally resilient.

The structural resilience of the mobile sectors can be obtained and controlled both by the appropriate choice of the types of plastics from which the internal and intermediate units are made, and by establishing an optimal thickness of the material layer for each unit. in the case of the RIR container 300, the walls of the inner unit 360 are preferably thicker and stiffer than those of the intermediate unit 340; the walls of the latter are preferably thinner and more flexible.

in the case of the RIR 300 container, the structural resilience, doubled by a non-linear behavior, may cause priority to be given to certain regions of the compression system 341; additionally, in the case of partitioning system 361, the type behavior of 2018 00505

04/07/2018 bistable / multistable can have effects even after the configuration is completed, ensuring an additional stiffening of the assembly.

Alternatively, the mobile sectors with the role of compression system (in the case of the RIR 300 container, those related to the intermediate unit 340) can also be made in the form of thin membranes that do not have resilience / elasticity / structural capacity.

Membranes can function - at least to some extent - similarly to mobile sectors that have structural resilience, using analogous factors, including:

lack of free edges; the edges of the membranes are connected to the laminated structure of the RIR container, by means of a fastening system a particular perimeter geometry, geometry derived mainly from:

the contour / shape of the clamping system, especially of the residual interfaces

- shape of the middle zone; for example, in the case of the alternative container RIR 420 (fig. 8), the shape of the protuberances 424

- side profile of the RIR container; the geometry of the side walls of the RIR container generates a corresponding profile for all internal mobile sectors - including membrane-type ones - a profile that influences the position and even the final shape of these mobile sectors.

Thus, at the end of the movement, the membranes can end up being superimposed over the walls of the partitioning system because - given the exposed conditions - it is the only available position; possibly there may be variations of the final position - close positions, possibly even anticipated.

Membranes therefore have the potential for a controlled operation - at least in part. Membranes also fall into the category of mobile sectors. In this respect, the claims of the invention do not differentiate a priori between structurally resilient or non-resilient mobile sectors; unless explicitly specified - or not apparent from the context - otherwise, references to mobile sectors refer to all of them.

The next section details some other elements related to the design and configuration of RIR containers.

In order to further stiffen the RIR 300 container, the two walls of the partition system 361 derived from the unit 360 can be joined by the joint 383 (fig. 6a - 6b and fig. 7), either partially or over the entire height of the RIR 300 container. the joint 383 can be made with adhesive. Laying the adhesive on the inner surface of the walls of the partition system of 2018 00505

04/07/2018 may precede the compartmentation or may take place simultaneously with this process; the dimensions, shape and number of elements from which the joint 383 is made may vary.

During bottling, the two liquids are preferable - but not mandatory - to be introduced into the RIR 300 container at the same time. The parameters of the bottling process (liquid speed, pressure, etc.) can be adjusted dynamically during the introduction of liquids - even for each liquid. - to facilitate compartmentalization.

According to the main variant of the invention, the balancing of the internal pressure in the RIR 300 container - as the liquids stored in the side compartments 310 are consumed - is achieved with the help of atmospheric air.

The access of atmospheric air is made through the upper part of the container RIR 300, using a mechanism whose elements are incorporated in the region of the upper segment 301; the elements of the respective mechanism can be made from the production phase of the component preforms of the preform set 200.

Thus, the enclosure 226 (fig. 2 and fig. 3a) is formed between the circular walls 224 (interior) and 225 (exterior) present at the upper part of the preform 220 (hence the external unit 320). in the enclosure 226 arrives - after assembling the set of preforms 200 - the flexible perimeter flap 245 (fig. 2 and fig. 3b), which forms a common body with the preform 240 (respectively with the intermediate unit 340); the perimeter flexible damper 245 acts as a directional valve. Flange 244 (Fig. 2 and Fig. 3b), adjacent to the flexible perimeter flap 245, closes the enclosure 226 at the top.

Atmospheric air can enter the enclosure 226 through the recess 227, made in the outer circular wall 225 (there may be several recesses of this type). After passing through the flexible perimeter damper 245, the atmospheric air reaches through the recesses 228 (fig. 3a) - recesses made in the inner circular wall 224 and continued descending vertically through the grooves 232 - between the units 320 (external) and 340 (intermediate), feeding the two lateral free spaces 311 (fig. 6b).

in the normal position, the flexible perimeter flap 245 has the lower edge (free) in contact with the inner surface of the outer wall 225 below the level of the recess 227; Consequently, the flexible perimeter damper 245 does not allow air to escape from inside the RIR 300 container.

The internal pressure in the RIR 300 container may be permanently the same in both side areas, including both side storage compartments 310 for liquids; the enclosure 226 - being common to the two side areas of the RIR 300 container - allows the communication between the free spaces 311 by means of the two recesses 228.

and 2018 00505

07/04/2018

Alternatively, the inner circular wall 224 may be omitted in certain configurations; its role can be taken over by the circular wall of the upper segment 241 of the intermediate unit 240.

Alternatively, some of the elements of the internal pressure balancing mechanism may be made in the form of separate components, for example: perimeter flexible damper, an independent closing element which can replace the flange 244, etc.

Alternatively, flange 244 may be completely omitted; in this case the clearance 227 may also be omitted.

The following section sets out a number of alternative components, characteristics and processes for making IRR vessels, in addition to the few alternatives mentioned above; the variants presented conform to the concept of unity of the invention.

Alternatively, the partitioning of an RIR container can be performed prior to bottling the liquids, using another fluid - for example compressed air; this prior compartmentalization may be partial.

Alternatively, the configuration of the compartments of an RIR container can be done following the blow molding step, as long as the container is still in the mold in which the respective process took place. The configuration may involve - but it is not mandatory to use a fluid other than liquids bottled in the side compartments (eg compressed air, another type of gas, a liquid product, etc.).

Alternatively, in an IRR vessel, suppression of interfaces between the side walls of the external and intermediate units may precede compartmentalization; the process may involve the introduction of a fluid (eg compressed air) between the two units. The introduction of the fluid can - possibly - be done by means of the internal pressure balancing mechanism, if the respective RIR container is equipped with such a system. Subsequently, in order to eliminate the fluid between the external and intermediate units and to allow the partitioning between the intermediate and internal units, the perimeter flexible damper can be operated from the outside in the case of the RIR 300 container by releasing 227 (fig. 4a).

Alternatively, in an RIR container whose storage compartments are configured prior to liquid bottling, suppression of interfaces between the side walls of the external and intermediate units may occur, at least in part, after configuration of the storage compartments, but prior to liquid bottling. A possible method of exfoliation is that indicated in the previous paragraph, using a fluid.

and 2018 00505

07/04/2018

Alternatively, in an IRR container - regardless of the time of compartmentation, exfoliation between the surfaces of the side walls of the external and intermediate units may occur, at least in part, during or after bottling of the liquids. The method of exfoliation may consist, similarly to the previous alternative, of introducing a (small) amount of fluid - for example compressed air - between the two units, by means of the internal pressure balancing mechanism.

Alternatively, certain containers configured using the alternative methods presented in the previous three paragraphs - by means of a fluid introduced between the external and intermediate units - may remain pressurized to a certain level; the compressed air is therefore not completely exhausted (or is not exhausted at all, if it has been introduced in small quantities). Maintaining a certain value of pressurization can ensure - together with the other components and characteristics involved in the configuration and operation of RIR containers - better control over the operation of these containers. For example, it can assist the start-up phase of the compression system operation and can also provide additional structural strength during product packaging and transport. However, the possibility of maintaining a certain level of pressurization also depends on the shape of the containers; for example, circular containers are better suited to such a technical solution.

Alternatively, the configuration of the storage compartments of an RIR container can be done by mechanical means or by adopting a hybrid solution, thus using a combination of methods. Mechanical means may include, for example, the insertion of a mechanical part between the units between which the storage compartments are configured; the configuration may also involve moving that mechanical part on the side axis, for example from the outer walls to the central area of the container.

Hybrid configuration involves a combination of methods, used simultaneously or successively. For example, mechanical means may be used in combination with a fluid: a tube penetrates to the base of the RIR container the interface between the side walls of the units between which the storage compartment is formed; the respective tube can be moved - but it is not obligatory - on the lateral axis; simultaneously or subsequently, a fluid can be introduced through said tube - for example the liquid to be stored. Other combinations of methods may be used; the present invention does not further insist on them, some combinations being apparent.

Alternatively, the invention also presents an RIR 430 container (fig. 9) - derived from the main variant - which provides for the introduction of liquids between the walls of the external units 431 and intermediate 432. The side walls of units 432 and 433 - connected through the interface 434 - can be 2018 00505

04/07/2018 move unitary towards the median on the longitudinal axis of the RIR 430 container, forming a partition system (with laminated structure) with double wall; two storage compartments are formed in the side areas of the container 435. At the upper end of the container, the shape of the constituent units will be adapted to allow bottling of liquids.

In operation, the side walls of unit 432 detach from those of unit 433 and move towards the walls of the external unit 431. As an alternative, the side walls of units 432 (intermediate) and 433 (internal) can be separated from an earlier phase. cycle of use - before, during or after bottling of liquids - by applying one of the exfoliation methods indicated above.

To balance the internal pressure in the RIR 430 vessel, atmospheric air may be introduced between units 432 and 433; In this sense, a mechanism (not shown) derived from that of the RIR 300 container can be used. That mechanism can be adapted. The recesses made in the inner circular wall of the respective mechanism for air access between units 432 and 433 - recesses equivalent to recesses 228 (fig. 3a) of the RIR 300 container - may be located in the region of the median area 436 and may penetrate the surface of the intermediate unit 432.

The perimeter flexible flap and the sealing flange are preferably produced separately and mounted after the introduction of liquids, in order to allow the bottling process to take place; any dispersing devices used may be adapted accordingly.

Alternatively, the invention also provides an RIR 440 container (Fig. 10) made of four units. Liquids are introduced between the two intermediate units 442 and 443. The partition system, laminated, consists of the side walls of the intermediate unit 443 and those of the internal unit 444; storage compartments 447 are formed in the side areas. In operation, the walls of the intermediate unit 442 detach from those of the external unit 441 and move towards the partitioning system; the walls of the intermediate unit 443 detach from those of the internal unit 444 and move towards the outer walls of the RIR 440 container. The internal pressure balancing mechanism (not shown) can take elements from both the RIR 300 container and the RIR 430.

Alternatively, the invention also presents an RIR 450 container (fig. 11) made of only two units. The walls of the partitioning system can be obtained by reconfiguring the side walls of the indoor unit 452 (in a manner similar to reconfiguring the indoor unit of the RIR 300 container). The RIR 450 container can have several functional variants:

and 2018 00505

04/07/2018 in a first variant, the RIR container offers two lateral storage compartments 454, with fixed geometry - the walls of the partition system are not mobile; the joint 453 may be present between the walls of the partition system to stiffen the assembly in another embodiment, the walls of the partition system are movable; they also act as a compression system for the liquid storage compartments: in operation they return - as the liquids are consumed - to the side walls of the external unit 451; joint 453 may be omitted if the latter technical solution is adopted.

Alternatively, RIR containers (not shown) - derived from the RIR 450 container (fig. II) - which have a single internal storage compartment, formed between the walls of the two units, can also be made; the two constituent units of the RIR container may not be connected by a clamping system.

Alternatively, RIR containers (not shown) - partly similar to conventional ones - can be made with two constituent units and a single storage compartment, a compartment created inside the indoor unit.

Containers of this type made in accordance with the present invention are suitable - in contrast to conventional ones - to incorporate in the external multilayer structure:

regions with distinct functional role and / or design features capable of performing functional role.

in certain constructive variants they can also have:

a fastening system between the constituent units;

possibly reinforced clamping system with dedicated design features.

Also, structurally, the internal unit can be of the type:

resilient - mobile sectors can have controlled operation non-resilient - mobile sectors can be membrane type, offering the potential for a partially controlled operation.

Alternatively, RIR containers (not shown) with more than two storage compartments can be made. An alternative RIR container can also be made of three constituent units - similar to the RIR 300 container - but, due to the different partitioning, it can have more than two storage compartments.

and 2018 00505

04/07/2018 (In an RIR container with more than two storage compartments it can be made from a number of constituent units other than three.

Alternatively - for any of the multi-chamber construction variants the storage compartments may have volumes of different sizes and / or may be asymmetrical (variants not illustrated).

in the case of an RIR 300 container, volumes of different sizes can be obtained simply by introducing different amounts of liquid into the incipient side compartments. During the configuration / bottling of liquids, the partitioning system may position itself differently from the main embodiment of the invention; the method is also applicable if the configuration of the storage compartments - possibly partial - precedes the bottling of the liquids. Thus, at the end of bottling, one side compartment will comprise an amount of liquid greater than half the total volume of the RIR container and the other a smaller amount.

Alternatively, the partitioning system of a multicameral RIR container may be positioned on coordinates other than the longitudinal axis - as shown in the illustrations of the invention; for example, the partitioning system may intersect the median on the longitudinal axis; the resulting storage compartments may have the same or different volumes (not shown).

Alternatively, the partitioning system may be configured with a geometric shape other than the substantially linear one exemplified in FIG. 6a - 6b, fig. 7 and fig. 8 - 11, for example semicircular, elliptical, etc ..

Alternatively, RIR containers can be made that have storage compartments that communicate with each other; the clamping system between the constituent units of such IRR vessels may be partial; RIR containers of this type are likely to store only one type of fluid.

Alternatively, RIR containers made in accordance with the present invention may have shapes other than those shown in the illustrations of the description - for example they may be substantially cylindrical, the base may have a petaloid shape, etc .; also, their volume can have the most varied values.

Alternatively, internal pressure balancing can also be achieved by introducing a pressurized fluid into dedicated areas inside an RIR container (dedicated areas such as free spaces 311 of the RIR 300 container), a method especially applicable to RIR containers that store liquids under pressure (carbonated beverages). etc.).

and 2018 00505

07/04/2018

Alternatively, various components, processes and characteristics related to the RIR containers set out above can be combined to make variants of RIR containers; the invention does not further insist on them, many combinations being obvious.

Alternatively, in the design and manufacture of IRR vessels of the type indicated above, technologies not currently used in this field may also be applied. The design phase may involve - for example - a generative design process, possibly in combination with AI (artificial intelligence) and / or cloud computing.

The scope of the present invention extends to all components, processes, and manufacturing and functional characteristics mentioned / detailed in the description and claims, regardless of how the RIR containers are designed.

Alternative production methods can be adopted in some cases for the manufacture of RIR containers - for example additive manufacturing, 3D printing.

Certain parts or components - such as the partitioning system - can be obtained without the need for preconfiguration; however, the operation of the system may bear similarities to at least one of the embodiments of the present invention.

The invention claims protection - consequently - also on alternative ways of manufacturing RIR containers.

Further details of the multifluid atomizer The invention details a multifluid atomizer 500, suitable for operation together with an RIR 300 container. The operation of the multifluid atomizer 500 is based on principles similar to those of conventional atomizers equipped with a manually operated pumping mechanism.

Among the elements of the main body 550 are:

two cylinders 564, which constitute the pressure lifting chambers the seats 560 and 561 (fig. 14 - 15) accommodate some components of the valve system the holes 563 (fig. 15) connect the seats 561 and the cylinders 564 the semi-cylindrical pipes 570 and 571 are part of the liquid discharge system the front part of the main body 550 forms together with the spray nozzle 850 the liquid spray assembly.

The valve system 600 (fig. 12 and fig. 15) consists of two valve assemblies. Each assembly consists mainly of a valve 602 and an annular gasket 601; an axle 609 joins the O-ring 601 and the valve 602. An additional axle 610 connects the two valve system assemblies 600.

Valves 602 reach the slots 561 of the main body 550. Each of the valves 602 consists of:

sealing base 606 - which seals the opening at the bottom of the seat

561 correspondent

- Perimeter (cylindrical) flexible flap 605 - acting as a semi-flexible crown direction valve 603 - acting as a pre-compression mechanism and which in turn comprises a semi-flexible crown:

- the perimeter region (circular) 604, with sealing role - the surface of the region the perimeters 604 is in contact with the internal surface of the seat 561 corresponding to the horizontal wall 608 (fig. 15) - blocks, in operation, the vertical (downward) circulation of liquids through valve body 602; it also exerts a control on the degree of flexibility of the semi-flexible crown 603, and therefore of the precompression.

The arrangement of the regions 607 (fig. 15) of the valves 602 dictates - within the main body 550 - the location of the orifices 563 (between the seats 561 and the cylinders 564); the positioning of the holes 563 between the upper edge of the perimeter flexible flaps 605 and the lower edge of the perimeter regions 604 allows the system to operate according to the present description.

and 2018 00505

The annular gaskets 601 reach the recesses 560 (fig. 14 and fig. 15) and have the role of sealing the openings at the bottom of the respective recesses.

The bridges 609 are also sealing elements and reach the lower part of the connecting spaces 562 between the recesses 560 and 561.

Bridge 610 reaches the clearance 566 (fig. 14).

The following paragraphs summarize the stages of operation of the multifluid atomizer.

The liquids are taken from the compartments 310 of the RIR container 300 and transferred inside the recesses 560 of the main body 550 through the tubes 655 (fig. 15) - tubes integrated in the sealing assembly 650 (the sealing assembly will be detailed later); the upper part of the tubes 655 penetrates the annular gaskets 601 of the valve system, gaskets present, as already mentioned, at the base of the recesses 560.

The liquids then pass into the slots 561 through the upper part of the connecting spaces 562 (above the decks 609). The flexible perimeter flaps 605 allow the access of liquids to the holes 563 and - further - to the cylinders 564.

When operating the atomizer, as the pressure increases, the liquids are discharged from the cylinders 564 also through the holes 563; the perimeter flexible flaps 605 block the access of liquids to the lower area of the seats 561.

Increasing the pressure above a certain level in the seats 561 leads to partial compression of the semiflexible crowns 603 of the valves 602; the perimeter regions 604 of the semi-flexible crowns 603 partially lose contact with the inner surface of the seats 561; the liquids are thus forced towards the upper extremity of the seats 561.

The liquids are transferred in the subsequent stage - through the holes 565 (fig. 14) - in the evacuation circuit, in the semi-cylindrical pipes 570 and 571 (fig. 14 and fig. 15);

Then, the liquids reach the front of the main body 550, in the spray assembly.

The following paragraphs detail the spray assembly.

Fig. 16 shows the front part of the main body 550 and the adjacent spray nozzle 850, with a view of their interior. Fig. 17-18 show the same two components, illustrated at the same angle as in fig. 16, but from the opposite direction; Fig. 17 provides a view of the front of the spray nozzle 850; Fig. 18 illustrates the front region of the main body 550, in vertical section, with a view from the rear to the front.

a 2018 00505 04/07/2018 in the front part of the main body 550, a cylindrical region 580 (fig. 14) is continued towards the rear with a frustoconical region 590 (fig. 14 - 15); the frustoconical region 590 has a large open base, following the cylindrical region 580, and a small closed base. The horizontal semi-cylindrical pipes 571 intersect the frustoconical region 590 (fig.

and fig. 15); the inner paths 573 (fig. 18) of the semi-cylindrical pipes 571 flow into the frustoconical region 590 in the form of openings 592 (fig. 16) made on the inner face 591.

The cylindrical element 593 (fig. 16), of rod type, is arranged in the center of the small, closed base, of the frustoconical region 590 and has two longitudinal grooves 594, as well as a vortex chamber 595, in the front part.

The spray nozzle 850 has some elements corresponding to those in the front of the main body 550. After coupling the spray nozzle 850 to the front of the main body 550, the corresponding elements of the two components come into contact: the outer face 852 of the frustoconical region 851 of the spray nozzle 850 comes into contact with the inner face 591 of the frustoconical region 590; the cylindrical element 593 reaches inside the cylindrical channel 853; niches 854 are communication channels.

The spray nozzle 850 can rotate around the cylindrical element 593, having two positions: closed, when the spray of liquids is blocked, and open, when the spray is allowed.

in the closed position, the face 852 of the frustoconical region 851 of the spray nozzle 850 closes the openings 592; the niches 854 are arranged offset - at an angle of 90 degrees - from the grooves 594 made in the cylindrical element 593.

By rotating the spray nozzle 850 to 90 degrees in the open position, the niches 854 allow communication between the openings 592 and the grooves 594. The liquids then reach the vortex chamber 595 - where they are mixed - and are subsequently discharged from the multifluid atomizer 500 through through hole 857 (fig. 17).

The following paragraphs detail some components and features of the 500 dispersing device.

The attachment of the multifluid atomizer 500 to the container R1R 300 is made by means of the base 551 of the main body 550; the protrusions 553 in the recess area 552 (fig. 14 - 15) - protrusions oriented towards the inside of the base - are engaged at the recesses 231 (fig. 4b) in the area of the upper segment 301 of the RIR 300 container.

The liquid evacuation routes can be made unitary (uninterrupted) inside the main body 550, in the phase of injection molding of this part. The interior routes of 2018 00505

04/07/2018 of the semi-cylindrical pipes 570 (vertical) can be practiced using the openings 565 (fig. 14), and those of the semi-cylindrical pipes 571 (horizontal) using the openings 592 (fig. 16). The inner paths of the two semi-cylindrical pipes 570 and 571 can form an angle of 90 degrees and can be found in region 572 (fig. 15).

In order to stiffen the main body 550, the horizontal semi-cylindrical pipes 571 can be joined to the axle 555 (fig. 14 and fig. 15), the deck continued at the rear with the bracket 556 as a support for the return spring 700.

The return spring 700 can be made of plastics of acetal / polyacetal type or of another type; the two curved arms 701 store - and subsequently release - some of the energy introduced into the system by operating the device. The return spring 700 is fixed to the main body 550 by means of the fixing base 702; the curved arms 701 reach one side and the other of the cylinders 564 (fig. 13); the gripping elements 703 come into contact with the actuating element 800, in the upper lateral areas 802 of the latter.

The actuating element 800 is fixed by means of the pins 801, located at the upper end, in the recesses 554 of the main body 550.

The set of pistons 750 consists of two pistons 751 joined by the axle 752. Each of the two pistons reaches inside the corresponding cylinder 564 inside the main body 550. The set of pistons 750 is moved, under the action of the actuating element 800, by means of the protrusion 753 .

The sealing assembly 650 (fig. 12 and fig. 15) is part of the multifluid atomizer 500 and acts as an intermediate element between the latter and the RIR 300 multicameral container. The sealing assembly 650 ensures the closure of the RIR 300 container - of the side storage compartments - and also mediates the transfer of liquids from the RIR 300 container to the multifluid atomizer 500.

The sealing assembly 650 comprises: two closure elements 651; two tubes 655 (already mentioned); two fixing rods 656; flange 658.

Each of the closure elements 651 reaches the corresponding side compartment 310 inside the container RIR 300. In the sealing assembly 650, the free space 657 separates the two closure elements 651; the upper extremities of the walls of the partition system 361 of the RIR 300 container reach the free space 657.

Each of the closing elements 651 consists of a semi-cylindrical section 652, continued at the bottom by a petaloid section 653. The semi-cylindrical sections 652 close the side compartments 310 in the region of the upper segment 301 of the RIR container 300 (Fig. 4b). 653 petaloid sections - which, preferably, end up being 2018 00505

04/07/2018 arranged below the level of the upper segment 301 - offers the walls of the compression system 341 of the RIR container 300 contact surfaces on which to position itself. In the absence of petaloid sections 653, it is possible to form pockets with non-dispersible liquid at the upper end of the storage compartments 310.

The tubes 655 - through which the liquids are extracted from the side compartments 310 - form a common body with the closing elements 651; the holes 654 at the bottom of the tubes 655 penetrate the surface of the petaloid sections 653 (fig. 13 and fig. 15); the upper part of the tubes 655 is projected above the level of the flange 658.

The fixing rods 656 reach inside the valves 602 - at the bottom of them providing an additional fixing for the valve system 600.

The flange 658 acts as a connecting bridge for the closing elements 651 and a support for the rods 656. The protrusions 659 (fig. 13 and fig. 15) of the flange 658 help to fix the sealing assembly 650 to the main body structure 550 of the multifluid atomizer 500 ; the protrusions 659 reach the upper region of the recesses 552, provided in the lateral parts of the base 551.

Alternatively, a multifluid atomizer may be provided with immersed tubes for extracting liquids from the storage compartments of an RIR container. In the case of the atomizer 500, the tubes can be connected through the holes 654; the length of those tubes may vary. The atomizer may be provided with such tubes for one or more storage compartments.

Alternatively, a multifluid atomizer (not shown) - capable of dispersing liquids from an RIR container with compartments of unequal volumes - may have cylinders of different capacities; in turn, the corresponding pistons can have different sizes.
