Description

CONTAINER WITH MILLIMETRIC DIAMETER DISCHARGE NOZZLE, WITH A BREATH, WHERE THERE IS NO INITIAL VACUUM FORMATION AND DURING DISCHARGE OR SUCTION, AND THE AIR DOES NOT THROUGH THE LIQUID, RESULTING A UNIFORM FLOW, WITHOUT GYM, AND GIPHED, RECIPROTED FLIP.

FIELD OF THE INVENTION

[001] The present invention relates to technical and functional improvements specially created to significantly improve the use and operation of liquid containers, more specifically in the flow of liquids in said containers. For this purpose, the present invention defines various types of breather or communicating means of adaptable air intake for liquid packages whose body may be rigid, semi-rigid, flexible, disposable or not, among others. Such vents have the function of preventing the formation of a vacuum at the bottom of the container at the beginning and during the discharge of liquid, providing a uniform flow, without gouges and allowing, in some cases, the control of this flow.

[002] The neutralization of the vacuum is achieved by the fact that the aforementioned breather allows the external air to be directed directly to the bottom of the package, before the beginning of the discharge or suction of the liquid. In addition, this air flow does not pass through the liquid being discharged, thus providing different technical effects that result in benefits for the operation of the set.

[003] These properties are achieved using the principle of communicating vessels, which in a variant in which the nozzle through which the air enters (7) is closed, is achieved

[004] The toggle and similar mounted on the air inlet (7), allow to perform other functions; transport without leaks, mixing liquids, mixing liquid and powder etc. HISTORY OF THE INVENTION

[005] The principle of communicating vessels establishes the following: the levels of a liquid in two or more contiguous vessels are equal as long as the pressures on those levels are equal ”, as shown in Figure 1. In other words, when we have two vessels with free openings to the atmosphere the two levels will be the same.

[006] Due to this principle, by tilting the communicating vessels and keeping the pressures (usually atmospheric pressure) on the levels of the two vessels equal, these levels remain fixed and in a horizontal position so that the vessel that is in position the top will be without any liquid when they are close to the horizontal position, according to Figure 1E.

[007] From the horizontal position it is guaranteed that the vessel that is at the top will have no more liquid inside it and there will be no more air near the discharge nozzle of the lower vessel, as it left for the atmosphere to allow the discharge of the liquid . The horizontal position is

Petition 870180158284, of 12/04/2018, p. 9/98

3/39 reached before the tilted position (lower nozzle of the lower vessel), which is when the discharge of liquid from the vessel that is in the lower position begins. Therefore, when starting to discharge the liquid from the lower vessel, the external air will already be at the bottom of the lower vessel, preventing the formation of an initial vacuum or even during the discharge. Note also that there will be no possibility for any portion of liquid to flow through the upper vessel.

[008] The above is valid for two non-miscible liquids having equal densities. If the densities are different there will be a difference in level between the two liquids, which must be taken into account in the packaging design.

TECHNICAL STATUS

[009] All of the state of the art patent documents, which follow, have been analyzed and are constructively and with different configurations from this patent application, as shown below in the descriptions of the respective patent documents.

[010] In state-of-the-art packaging, the liquid outlet creates a vacuum at the bottom of the container, requiring the external air to go to the bottom of the packaging to fill that vacuum, which allows the flow to settle. Normally, external air enters through the container discharge nozzle, passing through all the liquid to reach the bottom of the package. Some examples can be mentioned, such as detergent packaging and most types of baby bottles. In these cases, the flow is usually not uniform, with splashes and gusts occurring. Often, the packaging is pressed to improve the

Petition 870180158284, of 12/04/2018, p. 10/98

4/39 outlet flow, however this often ends up causing the product to overflow through the discharge nozzle and the product to exit through the breather hole. In the case of traditional baby bottles, the baby sucks this air, together with the milk, causing colic.

[011] In order to resolve these state of the art problems, Brown's US patent document US5570796 reveals a bottle with a breather. This invention allows the bottle to remain at atmospheric pressure during use, so that a baby does not need to suck hard and the air is not inadvertently ingested. This invention has some variations, but the common concept is that at the vent outlet there is a chamber to contain liquid from the bottom of the bottle. At the same time, the chamber provides space for air to enter the top of the bottle. The chamber also has a larger volume than the volume of the breather tube, so that the chamber is never completely filled with liquid from the bottom of the bottle.

[012] Figure 2 shows two variants of the Brown bottle of the prior art. Figure 2A shows the return of the liquid through the breather tube that is stored in the chamber (125). A valve provides air intake without leaking liquid.

[013] Figure 2B shows another variation where the entry of air into the bottle is carried out through a labyrinth, that is, the liquid flows into the chamber (225) and the entry of air through a second tube (235 ), preventing leakage of liquid contained in the bottle. Brown's baby bottle has several limitations, which if not

Petition 870180158284, of 12/04/2018, p. 11/98

5/39 respected there will be leaks, which does not happen with the present invention. The limitations of the Brown bottle are as follows: tilt limited to 45 ° (column 5, lines 26 to 30); does not allow rotation, that is, fixed position; it does not allow shaking, as there will be leaks through the maze, the transport must always be vertical. In addition, the breather liquid and the outside air go in the opposite direction. The liquid is retained in a reservoir at the end of the breather, to allow air to enter (Figures 2A and 2B). In other words, there is an initial vacuum formation (column 4, lines 13 to 16), highlighting the section the air only enters when the liquid begins to flow out ”.

[014] It is noted from the analysis of Figures 2A and 2B that, in Brown's invention, the liquid of the breather and the external air move in opposite directions, whereas in the present invention the liquid and air move in the same direction, as shown in Figures 2C and 2D.

[015] In addition, the present invention (Figures 4A to 4E and Figure 5) differs from the Brown document in that it does not need the chamber to contain the liquid at the top of the container. The Brown bottle chamber makes the manufacture of the object more complex, the space used by the chamber decreases the useful volume of the container, in addition to the chamber making hygiene difficult. On the other hand, the present invention advantageously provides a more simple and efficient way of preventing vacuum formation at the bottom of the container. In the present invention, the horizontal portion of the breather duct is advantageously enlarged and is positioned at the bottom of the container, instead of being just a hole in the side of the container. When the

Petition 870180158284, of 12/04/2018, p. 12/98

6/39 container is inclined to be poured or sucked, the liquid does not return through the breather however.

[016] Patent document PI0300664-6 discloses a vent for liquid containers positioned vertically, the lower end of which is positioned on the nozzle (6), on the side wall of the bottom part of the bottle, while the upper end is positioned on the outside and approximately at the height of the bottle cap. Said upper end has the function of allowing external air to enter the bottom of the bottle. The air passes through the duct (without passing through the liquid) and prevents the formation of a vacuum at the bottom of the package. However, the Brazilian patent document does not reveal the horizontal extension of the breather into the flask, which advantageously prevents the liquid from returning through the air duct, nor the air inlet (6) with another configuration (L >> O - Figure 5), nor the configuration shown in Figure 6. In this Brazilian document, as in Brown's invention, the air inlet orifice is installed on the side edge of the flask which allows easy return of the liquid through the breather duct, as shown in Figures 3A to 3D.

[017] The current patent application contemplates the particular case when the diameter of the discharge or suction nozzle is fractions of millimeters and there is air trapped under it as in the case of baby bottles (air in the nipple and neck of the bottle), to avoid shown in Figures 3A to 3D.

[018] When we start the discharge or suck, part of the liquid is retained at the end of the breather (6), by the air that went to the bottom of the package, and may return, leaking.

[019] Morrone's bottle, WO2013033487, has an outer container and an inner container, adapted to fit the outer container. This invention is provided by an air passage between the containers. When the bottle is inverted, the air moves between the walls of the containers until it enters a point in the inner container. On the other hand, the present invention advantageously provides a duct that takes the air from the outside to the bottom of the container, which makes the manufacture of the object simpler and less expensive. Another feature of this prior art invention (which is also seen in Brown's patent document) is that air enters the container after the liquid leaves. The air contained between the two reservoirs goes into the internal reservoir (30), when the liquid is sectioned (page 7, lines 23 and 24 and page 10, lines 5 to 10), with emphasis on the section (...) because as a vacuum develops in the inner container during use, the air outside the bottle displaces the volume of liquid consumed to equalize the pressure ”.

[020] However, in the present invention, air enters before the liquid leaves. In other words, in the present invention there is no formation of an initial vacuum during the discharge or suction of the liquid. Due to the principle of communicating vessels, even before the discharge or suction of the liquid begins, the air is already at the bottom of the packaging.

[021] Dominick's patent document US7984818 has an internal vertical or angled vent with a float on one end and a labyrinth on the other. When starting to feed, the inside of the bottle is

Petition 870180158284, of 12/04/2018, p. 14/98

8/39 pressurized and the liquid from the breather (1600) goes to the reservoir (1601) at the end of the breather (1221) allowing air to enter (1213). Air and liquid go in opposite directions. First the liquid corresponding to the first suction comes out and then the air enters (page 3, lines 2 to 8). The present invention, on the other hand, advantageously has characteristics that allow air to enter the bottom of the container first and only then the liquid flows out in a continuous flow through its discharge orifice.

[022] Patent document WO2009102980 by Sung and Bruce discloses bottles that can be ventilated to allow air to enter the container through a passage (41) as the liquid is removed. A filter (44) and a one-way valve (46) can be provided in the passage.

[023] As can be seen in the document by Sung and Bruce, air enters after the liquid leaves. In the present invention, advantageously the air is already at the bottom of the container for the liquid to escape. An excerpt from Sung and Bruce's document follows that shows this conceptual difference between inventions: the bottle can be ventilated to allow air to enter the bottle through a passage (41) as the liquid is removed ”. See also: page 5 lines 3, 4, 13 and 14 and claim 1, page 13, line 9.

[024] Berkovitch's US20090071926 patent document is equipped with a vertical, straight, centrally positioned, chamfered end. In this invention, the air intake is provided in the cover itself and a one-way valve is also provided. In this invention, the liquid

Petition 870180158284, of 12/04/2018, p. 15/98

9/39 flows through the formation of a vacuum, even if a small vacuum is necessary, as can be seen on page 3, paragraph 35: (...) liquid to freely flow the container under minimum vacuum ”. Another highlighted passage is on page 3, paragraph 43: The ventilation system (215) allows air to enter the container (200) to compensate for the liquid that leaves the container and thus prevent more than a minimum vacuum from forming inside the container. container". On page 4, paragraph 51: The valve (700) allows air to enter the container to prevent anything but a minimum vacuum from forming ”.

[025] In another Brown document US20110233236 a breather is provided to prevent the vacuum inside an inverted container and eliminate the components found in other openings of the container. The breather uses a conical ventilation duct that extends from the closure and an air duct that extends inferiorly from the closure. The use of collectors (6) and internal flanges (10) on the breather is an indication that the liquid that is in the breather does not fully reach the bottom of the package and may leak when the package is tilted, as can be seen in paragraph 161, The optional flange (10), the retaining flange, is internal to the vent pipe and retains any fluid in the vent pipe or reservoir (6) while the container is in use ”and in paragraph 162, (.. .) how the reservoir holds any liquid that moves nearby into the vent tube ”. If the liquid does not come out of the vent entirely, there will be an initial vacuum to remove what is left in the vent. Paragraph 27 describes the following: another object of the

Petition 870180158284, of 12/04/2018, p. 16/98

The invention is to provide ventilation that provides air to the bottom and top aspect of the container while removing liquid from the container in use. That is, the liquid leaves for air intake. In claim 11: allowing atmospheric air to flow into the container to prevent the formation of a vacuum within the container when the liquid is removed.

[026] Marchant patent document US3648903 discloses an invention for viscous liquids, which are discharged by pressing a flexible container. When pressing the container, the check valve (27) closes the vents (25), increasing the internal pressure in the container, forcing the liquid to escape through the opening (23). In this invention, a forced pressure discharge into the container is taught, which is flexible, preventing air from entering the container. In the present invention, air does not enter for the liquid to escape under pressure in the container. Furthermore, in the present invention the container can be rigid, flexible or semi-flexible.

[027] In Dominick's patent document US20110309047 air and liquid flow in opposite directions. In this invention there is an initial vacuum, that is, the air only enters after the liquid leaves. In this invention: two situations can occur: (page 4, lines 1 to 22): a) the liquid inside the breather (1600) can remain there or move to the reservoir (1601), at the breather end (1221), by the action of gravity or b) The baby, when starting the feeding, pressurizes the inside of the bottle and the liquid from the breather (1600) goes to the reservoir (1601) at the end of the breather (1221) allowing the entry of air

Petition 870180158284, of 12/04/2018, p. 17/98

11/39 (1213). Air and liquid go in opposite directions. First the liquid corresponding to the first suction came out and then the air entered.

[028] Several other patent documents have this characteristic of the liquid leaving, creating the vacuum and the air entering. Among these documents we can mention: EP0399826, US7959044, US20110079570, US20120280001, WO2008091563, US20070181520, US7959044, USD681838, WO2006118699 and US20100032398, analyzed below:

[029] In the summary of document EP0399826: the container (138) has a liquid outlet (150) to distribute the liquid and a ventilation hole (53) to replace the dispensed liquid ”.

[030] In the summary of KR1020080017335: (...) a vent (18) in a top cap (16) allows air to enter a liquid coating vessel as the liquid is removed ”.

[036] In document USD681838 there is no breather, it is a simple ornamental design for conventional bottles, having two nozzles, one at each end of the bottle body without breather, air must enter through the spout as in conventional bottles and, therefore, the air enters after the liquid comes out.

[037] In WO2006118699, a vent in the lid allows air to enter the liquid holding container when the liquid is removed.

[038] In document US20100032398, no obstruction prevents air from entering the container. Consequently, suction at the nozzle is relieved by increasing suction.

[039] In relation to the bottles of Figures 19, 20, 21, there are also several other documents of the state of the art that do not reveal the inventive concept taught here. State of the art documents reveal containers that use a spring-loaded, vacuum-operated check valve with a diaphragm, with membranes or even manually operated ones, such as those disclosed in PI0406578-6, GB2532652, US2907485, US3768683, US4311245, US4339046, US4401224, US4723668, US5499729 and US5692627. These sophisticated constructions are nothing compared to the simplicity of what is proposed in the present invention. In the patent documents above, it is necessary for the liquid to leave the air to enter, that is, a vacuum is created before the air enters.

[040] These bottles with check valves at the bottom will not allow you to heat the milk by bathing.

[041] Advantageously, in the inventions shown in Figures 19 and 20 the air is already at the bottom of the package by the simple movement of the container or bottle towards the discharge or suction, since the check valve (6) which is of the mechanical type , or disk C moves, allowing air to enter the bottom of the package, without creating a vacuum. Although the present invention also includes a valve, it is not activated by the mechanisms mentioned above.

[042] In document PI0720391-8, valve sets are provided for bottle ventilation. Advantageously in Figure 21 of the present invention, valves of any kind, rubber rings,

14/39 elastomer, not even flexible flaps to cover the holes and not even texturing. In the description of Figure 21, only a disc with capillary holes is provided that allows air to go to chamber A ”before the discharge or suction of the liquid, without creating a vacuum.

SUMMARY OF THE INVENTION

[043] The present invention teaches a container for the storage of liquids provided with a breather, where the container can take a plurality of shapes and may be a bottle or other containers with orifices of liquid exit in the order of millimeters, the liquid being conditioned by the container, provided with the necessary fluidity for the flow inside the container and in the duct. The breather has communicating means of air intake adaptable to the liquid container whose body can be rigid, semi-rigid, flexible, disposable or not, in addition to comprising a duct that is equipped with an upper opening for the entrance of air and an opening lower air outlet to the bottom of the container. The duct carries the external air to the bottom of the container without contact with the liquid and in accordance with the principle of communicating vessels, preventing the formation of an initial vacuum at the bottom of the container before the discharge or suction of the liquid begins.

[044] The duct can be positioned in several ways, the lower end of which is positioned inside the container or on its wall, while the upper opening is positioned on the outside of the container, approximately in height, below or above the lid. The vertical portion of the breather may be

Petition 870180158284, of 12/04/2018, p. 21/98

15/39 internally, in various positions, either attached to the container wall next to the internal wall or attached to the container body or lid or connected to the wall by means of a neck that defines the beginning of the horizontal portion of the duct that extends to the center or to the opposite wall of the container, preventing the return of the liquid through the vent duct.

[045] The present invention is additionally based on hydropneumatic balance. When one of the vessels (body of the package) has a lid with a discharge or suction nozzle open to the atmosphere and the other (breather tube) closed, we will have a pressure balance between the air that is confined to the breather and the liquid placed in the packaging, so that the liquid cannot flow into the breather. Thus, it will be enough to tilt the package for the air to go to the bottom of it and when it is horizontal, the vent should be opened to start the discharge, without the formation of an initial vacuum or during the discharge. With a toggle or micro valve, or an equivalent system installed in the breather, it will be possible to control the air intake and, consequently, the liquid outflow.

[046] Therefore, the hydropneumatic system is complementary to the part of the invention that is based on the principle of communicating vessels. That is, everything described and explained for the part of the invention that was based on the principle of communicating vessels is applied to the hydropneumatic system, adding the toggle, valve or equivalent, as shown in the constructions of Figures 17 and 18.

DETAILED DESCRIPTION OF THE INVENTION

[069] The purpose of the present invention is the construction of vents for packaging, where there is no initial vacuum formation or during discharge or suction and the air does not pass through the liquid, providing a uniform outlet flow. For this the following principles and properties of physics and properties of liquids are applied:

[070] 1) Principle of communicating vessels, according to Figure 1, considering more specifically when the discharge or suction nozzle (2) has a millimeter diameter (21) or fractions, for example, baby bottles (Figure 3). In this case, some constructive changes are necessary, so that this principle can be fully obtained, as we will see below: Figures 2C and 2D to 15.

[071] Figures 16 to 18 show a variant of the principle of communicating vessels where one of the vessels, or specifically the vent opening (7) is closed by a toggle or similar, obtaining a hydropneumatic balance, valid in all constructions of the item 1.

Petition 870180158284, of 12/04/2018, p. 26/98

20/39

[072] 2) Other constructions meet the objective of the present invention, such as Figures 19 and 20 and the use of surface tension and capillarity, Figure 21.

[073] Thus, in summary, part of the invention is based on the principle of communicating vessels, according to Figure 1; in the hydropneumatic pressure balance, according to Figure 16 and in the construction of packages that allow to reproduce the functionality of these two vents, according to Figures 19, 20 and 21.

[074] As shown in Figure 1, the levels of the liquid in two or more contiguous vessels will be equal as long as the pressures on those levels are equal. As shown in Figures 1B to 1E, when tilting the communicating vessels and maintaining the same pressure on the two vessel levels, these levels remain fixed and in a horizontal position, so that the vessel in the upper position will be without any liquid when they are close to the horizontal position, Figure 1E. From the horizontal position, it is guaranteed that the vessel at the top will have no more liquid in it and there will be no more air near the discharge nozzle of the lower vessel, as it left for the atmosphere, to allow the discharge of the liquid, as shown in Figure 1F.

[075] The horizontal position is reached before the tilted position, that is, when the nozzle of the lower vessel is facing downwards (Figure 1F), which is when the discharge of liquid from the vessel that is in the lower position begins. Therefore, when the discharge of liquid from the lower vessel begins, the external air will already be at the bottom of the lower vessel, preventing the formation of an initial vacuum or even during

Petition 870180158284, of 12/04/2018, p. 27/98

21/39 discharge. Note also that there will be no possibility for any portion of liquid to flow through the upper vessel, as shown in Figures 1C to 1E.

[076] The above is also valid for two non-miscible liquids with equal densities. If the densities are different there will be a difference in level between the two liquids, which must be taken into account in the packaging design.

[077] After several tests performed by the inventor, with different diameters of the liquid outlet nozzle, different diameters of the breather, in various types of packages and bottles, several embodiments of the invention were developed. However, all the embodiments of the invention are based on having air in the bottom of the package before discharge or suction (in the case of bottles) of the liquid, in order to avoid the formation of the initial vacuum and during discharge or suction. In other words, the outside air enters and then the liquid leaves. In the state of the art inventions the opposite occurs, first a portion of the liquid leaves, there is the formation of the initial vacuum, for the air to enter and allow the rest of the liquid to escape.

[078] The tests carried out revealed that depending on the diameter of the outlet nozzle, the diameter of the breather and the construction of the packaging or bottle and also depending on the speed with which the packaging is tilted for unloading, the principle of communicating vessels can be affected. This happens mainly when the diameter of the outlet nozzle (21) of the liquid is very small (in the order of magnitude of fractions of millimeters)

Petition 870180158284, of 12/04/2018, p. 28/98

22/39 bottles), as the air in the upper part of the packaging, next to the discharge or suction nozzle does not leave the packaging when it is tilted. That is, when the package is tilted, to discharge the liquid, the air trapped in the nipple of the bottle tends to go to the bottom of the bottle and not out of the package. This feature prevents the entire liquid in the breather from going into the package, that is, so that the air from the breather can reach the bottom of the package. This difficulty is shown in Figure 3, with external and internal breather. The residual liquid that remains in the breather can go to the baby's face when he performs the first suction.

[079] Despite the example of the dynamics of air inside bottles, the same is true for other types of containers that have a small hole and the air located at the top of the package does not immediately enter the atmosphere when the container is tilted. This can occur in packages of other products, which do not allow total air to escape from the discharge nozzle. In fact, this phenomenon will occur, as already mentioned, due to several factors such as the design of the packaging, diameter of the holes and the speed of the inclination of the packaging, etc.

[080] After testing, with various diameters of the liquid outlet nozzle, various diameters of the breather, in various types of bottles, various types of breather were developed which are disclosed here.

[081] Figure 4 shows the behavior of the communicating vessels, considering the vents (4) of the solution to avoid the problem shown in Figures 3A to 3D, that is, the

Petition 870180158284, of 12/04/2018, p. 29/98

23/39 end (6) of the breather, of the state of the art, is obstructed by the air that was below the nipple and neck of the bottle, and that went to the bottom of the bottle. In this solution the end (6) is extended in order to allow the liquid in the breather (5) to go completely to the bottom of the bottle.

[082] Figure 5 presents another solution to the problem pointed out in Figures 3A to 3D. The nozzle (6) where the breather enters the bottle body is made in a parabolic manner, where the vertical diameter is much larger than the horizontal diameter, which is equal to the diameter of the breather (5), preventing the accumulation of liquid, as shown in said Figures.

[083] Figure 6 is one more solution to the problem previously mentioned. In this case, a system was developed that avoids the air that is in the space (E) of the bottle's nipple and neck from going to the bottom of the bottle, causing the problems pointed out in Figures 3A to 3D.

[084] This is achieved by trapping the air above the transverse plate (P), through the liquid, by tilting the bottle (Figure 6C), forcing it to go out into the atmosphere through the tube (5A).

[085] Note that while the bottle is tilted, there will be liquid in this tube, due to the principle of the communicating vessels (bottle body (1) and tube (5A), connected by space E).

[086] As the bottle is tilted, the liquid occupies the space (E) and expels the air from that space into the atmosphere and the liquid goes up through the

Petition 870180158284, of 12/04/2018, p. 30/98

24/39 tube (5A) to a level compatible with the level of the liquid inside the bottle, due to the principle of communicating vessels, as explained above. As the bottle is returned to an upright position, the liquid in the tube (5A) quickly returns into the bottle, also due to the principle of communicating vessels.

[087] Therefore, in order to improve the construction and configuration and performance of the packaging breather, with a very small discharge nozzle (or liquid suction) (fractions of millimeters), the invention and its constructive variations are presented here.

[088] We describe below the invention and its constructive variations, the invention comprising: a breather (4) defined by a system of communicating vessels represented by a breather (4), a conduit (5) of suitable diameter, which can be positioned in various ways, the lower end of which (6) is positioned inside the container (1) or on its wall, while the upper end (7) is positioned on the outside and approximately in height, below or above the lid , where said upper end (7) configures the entry of external air through the vent (4) exiting at the lower end (6) at the bottom of the flask, without passing through the liquid (L). Thus, the present invention provides that the liquid from the breather tube (4) can go to the bottom of the package, by simply tilting the package (bottle etc.), without crossing the liquid (L) and preventing the formation of an initial vacuum in the bottom of the container (1) even before the liquid is discharged or sucked (bottle).

Petition 870180158284, of 12/04/2018, p. 31/98

25/39

[089] Various embodiments of the invention will be presented in this document, however without limiting the scope of protection of the invention that is defined by the claims of this document. Thus, the breather tube (4), both the lower end (6) and the upper end (7) can be positioned in various ways as will now be shown.

[090] The breather (4) can have several configurations (external and internal) and its lower end (6) must be located in intermediate positions up to the center of the package or to the opposite side of the inlet (8) of the breather (4 ) on the packaging, as shown in Figure 7.

[091] Depending on the application and the shape of the breather tube (4), its lower end may have several shapes, allowing the package to be rotated 360 °, as shown in Figures 8A and 8B or maintained in an inverted vertical position at 180 ° according to Figure 8C, without the possibility of leaking the liquid, as long as the air is already at the bottom of the package, as there will be no more liquid in the breather (4).

[092] This property is excellent for baby bottles, for example, as the baby can turn the bottle and there is no limitation of inclination. The same principle applies to other packages that may have the lower end (6) in a straight or conical cylindrical shape, coaxial to the container, among others, all respecting the spirit of the invention.

[093] Likewise, the vent (4) can have several positions in relation to the body of the package, several

Petition 870180158284, of 12/04/2018, p. 32/98

26/39 constructive alternatives, several cross sections and several formats, within the same inventive scope.

[094] According to Figures 9A, 9B and 9C the vertical part of the breather can be internally, in various positions, or attached to the packaging wall (next to the internal wall) or attached to the body or the cover or connected to the wall through a neck. The breather can also be part of the packaging wall.

[095] The vertical part of the vent (4) can be attached or not to the external or internal wall or connected to it by means of a neck, as shown in Figures 9A, 9B and 9C. The horizontal part of the extended vent (4) can be attached or not to the internal or external wall (nozzle at the bottom of the package). This part can be tilted with respect to the bottom of the container (1).

[096] The breather (4) may be totally internal and have the opening of the upper end (7) in the body of the container (1) or in the lid (3), according to Figure 10A, or coupled to the nozzle (2) discharge Figure 10B. The vent (4) can be vertical, oblique, curved, straight or in various other shapes, as shown in Figures 10A, 10B, 10C and 10D.

[097] The lower end nozzle (6) can have several positions with respect to the vent axis, as can be seen in Figure 10D.

[098] The vent (4) can also be positioned completely outside the packaging, as shown in Figure 9.

[099] The vents (4) can be removable. The upper end nozzle (7) (air inlet) can be

Petition 870180158284, of 12/04/2018, p. 33/98

27/39 mounted on the lid (3) of the container (1), according to Figures 11A and 11B. The vents (4) mounted on the cover (3) can be removed along with it according to Figure 11B.

[0100] In another embodiment of the invention, the upper end nozzle (7), air inlet, can be mounted on the body of the package, according to Figures 11C and 11D.

[0101] Figure 11E shows a vent (4) that has its duct (17) fitting into the body of the container (1). In this embodiment of the invention the container (1) is provided with a cut (15) in its wall. Said cut (15) is wedge-shaped, where the outermost portion of the wall has a smaller opening than the innermost portion. The cut (15) extends to the upper portion of the container, configuring a fitting means for a closing piece (16) that also has a wedge shape and is integral with the wall providing a fitting means with the container (1). Said fitting is preferably carried out by the upper portion of the container (1) providing perfect sealing to the walls of the container (1). The closing piece (16) is provided with a duct (17) that extends from the upper portion of the container (1) to the lower portion thereof, in order to provide the passage of air to the bottom of the container. In the lower portion of the closing piece (16) the conduit (17) is attached to its respective extension (20) configuring a breather that extends towards the center of the container (1).

[0102] In another embodiment of the invention, the vents (4) are dismountable and removable, as shown in Figure 12. Two possibilities of

Petition 870180158284, of 12/04/2018, p. 34/98

28/39 vent (4) removable, as shown in Figures 12A and 12B. You can have different disassembly configurations, depending on the application.

[0103] In another embodiment of the invention the breather (4) is constituted using part of the container wall (1) and a flat or curved internal wall (12), as shown in Figure 13. Said internal wall (12) configures a conduit (5a) together with the container wall (1). Alternatively, the inner wall (12) may have an inclination that allows better flow of liquids, especially the more viscous ones. A hole (14) can be opened in the upper portion of the container (1) configuring a breather (4).

[0104] Another embodiment of the invention flexible breathing ducts (5) are provided, as shown in Figure 14. The flexible ducts (5) can be made of plastic and can have a metallic element so that it adapts to the varieties of container formats (1) existing on the market. The lower opening (6) can follow the position of the rigid vents (4) or others depending on the application, as long as it takes the air to the bottom of the container (1).

[0105] As seen, the ducts (5) of the breather (4) can assume a variety of shapes and characteristics. The conduits (4) can be:

The. rigid (Figures 7 to 12) or flexible (Figure 14);

B. demountable (Figures 10B and 12);

ç. using part of the container wall (1) (Figure 13);

Petition 870180158284, of 12/04/2018, p. 35/98

29/39

d. they can be fixed (Figures 7 to 9) or removable (Figures 10A, 10B, 10D, 11B and 11D);

and. a combination of the characteristics mentioned in the previous items.

[0106] One could also consider the use of telescopic vents (4) to install in packages of various heights. In all cases, ducts (5) of the vents (4), as well as the containers (1) can be constructed with cross sections (circular, square, rectangular, hexagonal, etc.).

[0107] Figure 1 illustrates some possibilities of breath formats: inclined, straight, curved, conical, etc. Other formats, which allow the realization of the principle of the invention, are also possible.

[0108] The container body (1) can also be split and threaded in order to facilitate cleaning, as in the case of baby bottles (Figures 19, 20, and 21).

[0109] As the air enters first and then the liquid leaves, the outlet of said liquid can be determined (forward or delayed) depending on the inclination of the lid (3), angle a ”as shown in Figure 14, and / or by means of at different positions of the nozzle (2) in the lid (3) of the container (1).

[0110] Considering the hydropneumatic balance depressions, if the pressure on the liquid in one of the contiguous vessels is greater than that of the other vessel, there will be no equality of the levels, as the liquid will not flow into the vessel with greater pressure (Figure 16). In this case, if we keep one of the vessels closed, when placing the liquid in the other, the liquid will not flow into the closed vessel to equal the

Petition 870180158284, of 12/04/2018, p. 36/98

30/39 levels, as in the case of the communicating vessels described above in Figure 1. The liquid will not flow, as the air trapped in the closed vessel will prevent this from happening, due to the pressure balance that is established, as shown below:

P1 = Pa + HJ, where: P1 is the pressure of the air retained, Pa is the atmospheric pressure, H is the difference in the level of the liquid in the two vessels and J is the specific weight of the liquid. Therefore, P1> Pa.

[0111] When the contiguous vessels are tilted, keeping the vessel closed at the top (Figure 17A), there will be no possibility of the liquid flowing into the closed vessel due to the pressure difference and, when reaching the horizontal position ( Figure 17C), you can open the closed vessel allowing the outside air to go to the bottom of the vessel that was open (at the bottom), without the need for the formation of the initial vacuum or even during the discharge. Similarly to the case of open communicating vessels (equal pressures in both vessels), there will be no possibility of liquid flowing through the upper vessel, which was closed. So it has to be that the following mechanism: the air enters and the liquid leaves.

[0112] Therefore, in the vents described that work according to the principle of communicating vessels, it is also possible to add at the air inlet, upper opening (7), a toggle (9), needle microvalve or similar device according to Figure 17, in order to keep the air inlet of the breather (4) closed. When placing the liquid in the container (Figure 17A) there will be no equality of levels, as the liquid will not rise

Petition 870180158284, of 12/04/2018, p. 37/98

31/39 through the vent (5) duct (4), due to the pressure balance, that is, the pressure created in the duct (5) is greater than the atmospheric pressure.

[0113] When the container (1) is tilted, there will be no possibility of the liquid flowing to the vent (5) duct (4), remaining in the container (1). When reaching the horizontal position (Figure 17C), the external air inlet can be opened, manually or automatically, allowing the air to go to the bottom of the container (1), therefore, there is no initial vacuum formation, neither during discharge or suction. Similarly to the case of the fully open external air inlet, there will be no possibility of leakage through the breather (4).

[0114] This construction has the same advantages mentioned above (in the previous embodiments of the invention), in addition to the possibility of allowing sudden movements (shaking) for mixing liquids with powders (for example, mixing milk with powdered chocolate), it is enough to close the external air inlet. In order to achieve these objectives, the toggle (9) and other similar devices can be installed along the vent (4), that is, from the upper opening nozzle (7) to the beginning of the horizontal portion of the conduit (5), as shown in Figure 18. Different types of valve (11) can be installed in the conduit (5) in order to provide a seal to it in a horizontal position. A needle (10) that fits into a seat can seal the top opening (7) and prevent air from coming out in a horizontal position. On the other hand, the same valve allows air to enter when the container (1) is tilted. The concepts of the achievements of

Petition 870180158284, of 12/04/2018, p. 38/98

32/39 previous inventions (vents, construction, position etc.), based on the principle of communicating vessels, are valid for this realization.

[0115] Initially we can prepare the bottle for feeding (air at the bottom of it) using the principle of communicating vessels or the hydropneumatic system. When the feeding is interrupted, it is more practical to resume the feeding using the principle of communicating vessels, since the toggle or equivalent device is already open, so there is no need to reuse it, as it would be more work , since to close it, the bottle would have to be placed in a horizontal position. The cap or equivalent device can be used for many other functions of the bottle: transport, shake, etc.

[0116] A practical application of the above construction would be a thermal bottle, as we can use the internal breather in order to keep all the liquid (body + breather) warm.

[0117] Alternatively, the container of Figures 8 to 13, 15 and 17 can be split (threaded), according to the embodiment of the invention that will now be described.

[0118] In another embodiment of the invention, the container (1) incorporates the vent (4): with the same concept of having air at the bottom of the container (1) before discharging the liquid, without forming a vacuum, when air inlet. In Figure 19, the air is already in chamber B (lung), which is separated from chamber A by a fixed plate C, having a lower opening (6), where a valve is installed, which opens and allows air to pass from chamber B to the

Petition 870180158284, of 12/04/2018, p. 39/98

33/39 when tilting the packaging. There is no command to open the valve, only the inclination of the package will open the valve, as in previous achievements. The opening (7), which communicates the external air with the chamber B, can remain open, or opened manually or automatically by a micro-valve or a hole or more capillary holes remains open, which does not allow the passage of the liquid, but allow air to pass through.

[0119] In another embodiment of the invention, it is shown in Figure 20. In this case, plate C is movable and when tilting the package it will move from its base allowing air from chamber B (lung) to pass to chamber A , through holes in the plate and its support. Similarly, the opening (7) provides external air for chamber B.

[0120] The set of Figures 21, show another embodiment of the invention. In Figures 21-I and -II, the container (1) has a screw cap at the bottom through which the air enters, through the thread, through holes or capillary tubes of the internal disk C (flat or conical, etc.). Capillary tubes have dimensions in the order of fractions of millimeters, according to the standards ABNT NBR ISO 7864: 2010 and NBR ISO 9626: 2003. When spilling the liquid (L) from the container (1), air passes through the holes in the disc, going from chamber B to chamber A, without the need for a vacuum to form at the bottom of the container (1).

[0121] Depending on the diameter of the capillary orifices and the viscosity of the liquid, the container (1) may be vertical when filled or when

Petition 870180158284, of 12/04/2018, p. 40/98

34/39 interruption of discharge or feeding, without dripping through these holes.

[0122] Note that the external air will already be at the bottom of the packaging or bottle, before discharge or suction, without the need for a vacuum to open valves, remove caps, flaps, among others, to unblock the holes for air intake. Capillary holes can also be understood as capillary tubes.

[0123] In another embodiment of the invention, shown in Figure 21-III, two discs are provided, to better retain the liquid, depending on the application. Thus, there is a loss of pressure when the pressure of the liquid decreases when crossing the first disc.

[0124] Figures 21-IV and -V show the realization of the invention where the holes or capillary tubes will be located in the body of the package, being dimensioned, both in quantity and in diameter to allow air to enter and not allow the liquid come out.

[0125] Figure 21-VI is an example of construction that can be done in several ways, the disk of which can be removed for cleaning and hygiene of the holes.

[0126] Figure 21-VII shows the realization of the invention in which the capillary spaces between blades B and C and between blade C and crown D fixed to the packaging wall are used.

[0127] Figure 21-VIII shows an inclined or horizontal base, to support the container (1) when you want to avoid dripping through the holes. In case the project requires holes with diameters that allow a drip, when the discharge or suction is interrupted, the

Petition 870180158284, of 12/04/2018, p. 41/98

35/39 container (1) may or may not be supported on an inclined support at an angle (a) suitable for the design of the container and the characteristics of the liquid (L). In this case, there will be no dripping through the capillary orifices, as the pressure exerted on the orifices is much less than that exerted when it is vertical (h and h '<< H). In the vertical, the container (1) can remain for a certain time, which will depend on the diameter and number of holes and the volume of the other chamber. Even in this case, when starting the discharge or suction of external air, it will already be at the bottom of the package, without the need for a vacuum to open valves, remove covers, flaps, etc., to unblock the holes for air intake. Capillary holes can also be understood as capillary tubes.

[0128] Thus, with the packaging corresponding to Figures 19, 20 and 21 and respective vents, the objective of the present invention is obtained, that is, there is no initial vacuum formation, neither during discharge or suction and the air does not pass through the liquid.

[0129] As with what we proposed above, a number of characteristics and advantages are achieved, among which we can highlight those described below.

[0130] There is no vacuum formation at the bottom of the container, before and during the discharge or suction of the liquid in any of the constructions described above.

[0131] Can be used for packaging with discharge or suction openings (21) having infinitesimal diameters.

[0132] The container in Figure 4D can be tilted at any angle, up to 180 ° and kept there

Petition 870180158284, of 12/04/2018, p. 42/98

36/39 tilt, vertical with the spout down, without any possibility of leakage, as there is no liquid in the breather, therefore, there is no possibility of draining liquid on the baby's face in the case of bottles, using or not the toggle.

[0133] In Figures 8A, 8B and 8C, once the breather liquid has drained (4) and maintained in the suction position, it can be rotated 360 ° around its axis, without any leakage of liquid through the breather ( 4). It is not necessary to close the toggle (9) at the air inlet, in order to be able to rotate, as a convenient study of the body of the packaging and the type and flow of the breather (4), allows to obtain this characteristic. This is another advantage for bottles, as the baby can turn the bottle without any danger of leakage on his face.

[0134] The outflow of the liquid can be determined (ahead or behind) depending on the inclination of the container (1) by means of different positions of the spout (3) on the lid (3) of the container (1) and the inclination of that lid ( angle a ”in Figure 15).

[0135] In order to allow bottle sterilization: a) the container body can be made in two threaded parts, split as in Figures 19, 20 and 21, and the vent nozzle diameter (4) must be dimensioned to facilitate cleaning. The breather (4) can be threaded onto the container body (1), to remove it and perform cleaning more easily (Figure 12).

[0136] The liquid contained in the breather (4) and the air go in the same direction towards the bottom of the container (1),

Petition 870180158284, of 12/04/2018, p. 43/98

37/39 requiring a labyrinth where the liquid can be deposited to allow air to pass.

[0137] It is possible to control the inlet air in the breather (4), which consequently controls the outflow of the liquid. For this, several devices: needle valve, toggle (9), which works not only open-closed, but also allow the adjustment of its opening, etc.

[0138] The external air goes directly to the bottom of the package without coming into contact with the liquid. In the case of baby bottles, air and milk are kept separate and avoids the baby's effort to form a vacuum and avoids gas, gas cramps, regurgitation and baby's hiccups, as there is not the slightest chance that a drop of air will even be absorbed for the baby, that is, there is a bottle that is 100% anti-colic.

[0139] The present invention allows to establish a uniform flow, because at the same time that a volume of liquid is discharged an equivalent volume of external air is directed directly to the bottom of the package where there is only air.

[0140] The present invention provides a more hygienic device, as there is no danger of leakage in the body and bottom of the package, as well as through the external air inlet hole, even when filling or unloading the package, or when pressing the same as in the case of flexible packaging.

[0141] The present invention provides a more economical device, as it is possible to control the flow of the liquid, adequately dimensioning the vent (4) through the diameter of the duct (5), the discharge nozzle (2)

Petition 870180158284, of 12/04/2018, p. 44/98

38/39 or using devices to measure the air intake and, consequently, measure the liquid outlet, which is ideal for certain packages, such as those for condiments, edible oils and others. In addition, there is no waste of liquid.

[0142] The present invention defines a simple breather (4) that dispenses with complex devices on the bottom, internally or on the container body, as well as intermediate parts and other complications and sophistications, double packaging etc., which require assembly and disassembly of the set, eliminating even the use of disposable parts or periodic replacement of certain parts, as well as special care for cleaning.

[0143] Depending on the application of the set, the duct (5) forms the vent (4) can be located internally or externally, as well as being part of the container; internally it can be placed in any position, from the central part (coaxial with the packaging) up to the inner wall of the container (1).

[0144] The duct (5) of the breather (4) may have its upper end (7), that of the air intake, located externally to the container (1), in the body or in the cap (3) of the bottle packaging.

[0145] With a small adaptation it allows the coupling of the duct (5) with a device for the suction of the liquid from inside the container (1).

[0146] In the case of bottles, devices available on the market can be coupled, so that the baby can suck the milk when sitting in the car or in the baby carriage, without using his hands.

Petition 870180158284, of 12/04/2018, p. 45/98

39/39

[0147] The present invention allows sudden movements (shaking), for mixing liquids or liquids and powders (chocolate etc.), just by closing the external air inlet, by means of a toggle (9), valve or similar device. These can be located along the breather tube, that is, from the upper opening (7) to the lower opening (6), according to Figures 18A, B, C and D.

[0148] The bottles of Figures 18, 20 and 21, of simple construction, also do not allow the creation of the initial vacuum, for the entry of air, even during suction.
