Cap for a liquid container

Abstract

The invention relates to a lid for consuming liquid from a container, the lid comprising at least one aperture for liquid to flow out of the container and at least one aperture for air to flow into the container, the air inlet aperture comprising a one-way valve which allows air to enter but not liquid to flow out through the one-way valve.

Description

Technical Field

[0001] This invention relates to a cap with a one-way valve for liquid containers, preferably the type of cap that connects to the opening of a container (e.g., a PET bottle), although the cap can also be used for other types of containers, such as bottles used by cyclists or athletes. Specifically, the cap described in this application can be applied to liquid containers and includes a spout for dispensing liquid, the spout rising from a surface that also includes an orifice with a one-way valve that allows air to enter the container but prevents liquid from exiting. The cap also includes a circumferential wall for fitting the cap onto the opening of the liquid container. The cap of the present invention allows air to enter the orifice uninterruptedly through the one-way valve, i.e., maintaining an air supply even if the orifice is blocked by the user's lips when the user inserts the spout into his or her mouth to drink.

[0002] This invention can be applied to the field of closures for liquid containers, particularly for containers for beverages (mainly water, isotonic beverages, soft drinks and juices) and for containers for sauces and other foods (especially liquids or partially liquids). Background Technology

[0003] In the prior art, sealing devices for liquid containers are known, which include an orifice for liquid to drain from the container and an orifice for air to enter the container, allowing the air to enter and facilitate the liquid's exit. Examples of such sealing devices are used in large-diameter cups or bottles, particularly for use by young children and the elderly.

[0004] Similarly, different mechanisms can be incorporated into the sealing device to prevent liquid from leaking out through the orifice by air. These mechanisms consist of elements that make it easier for users or consumers to drink the liquid. The sealing device mainly includes elements attached to or integrated into the body of the cap, particularly a one-way valve, which prevents liquid from leaking out of the container while being consumed, but allows air to enter for a smooth discharge of the liquid. When the element is attached to the cap, it is made of a material with specific properties, such as latex or silicone, while when integrated into the body of the cap, the valve is made of the same material as the rest of the cap.

[0005] Therefore, caps currently available for bottles of the aforementioned types, such as mineral water, soft drinks, and isotonic beverages, contain only a small orifice for liquid discharge, requiring the consumer to suck to extract the liquid or compress the receiver or container (if its material allows) to drink directly from the flow exiting the orifice. If the consumer sucks, problems arise from this sucking, such as the need to stop sucking to breathe and continue drinking, and deformation due to container collapse, indiscriminate wrinkling and / or compression deformation during sucking, leading to a change in container shape, especially when it is made of PET, making it difficult to hold. These problems are exacerbated if the consumer is a young child, someone recovering from illness, or an elderly person who needs to stop breathing, as uncontrolled sucking carries the risk of inhaling large amounts of liquid, potentially leading to suffocation. Similarly, in prior art caps, a sucking effect occurs when drinking stops, which is inconvenient for the consumer.

[0006] Similarly, the lid of the present invention can also be applied to containers used for sauces and other foods.

[0007] It is also known that a cap or closure includes, on the same body surface as the cap or closure device, an orifice for liquid discharge and an orifice for air inlet, the air inlet having a valve or one-way valve that regulates airflow into the container and prevents liquid contained within the container from leaking out. The valve is integrated into the body of the cap or closure device, forming a single body or part of the same single material; that is, the valve is the same part as the portion of the cap having the discharge orifice. A potential problem with these caps or closure devices having an orifice for liquid discharge and an orifice for air inlet (with or without a one-way valve) is that when a user inserts the liquid discharge orifice into his or her mouth, the user's lips may block the air inlet, thus preventing air from entering the container as liquid flows out. This problem is particularly pronounced in caps where the liquid discharge orifice in the nozzle is located close to the air inlet, because in this type of cap, the user can block the air inlet with his or her lips.

[0008] Therefore, the object of the present invention is a cover including an air supply system that ensures air reaches the orifice where the one-way valve is located, thereby allowing air to enter the container regardless of whether the air inlet orifice is blocked. Summary of the Invention

[0009] The object of the present invention is a cap for a liquid container according to claim 1. Specifically, the cap of the present invention includes:

[0010] - A circumferential wall that can accommodate the opening of a liquid container; and

[0011] - A first surface having at least one suction nozzle rising from the surface and at least one first orifice for discharging liquid from the container, the first surface also having at least one second orifice for allowing air to enter the container, and the second orifice having a one-way valve that allows air to enter the container but prevents liquid from flowing out; and

[0012] - An air supply system that extends from the circumferential wall to the second orifice to guide air from the circumferential wall to the second orifice.

[0013] The air supply system may be formed by the following:

[0014] - The two facing bodies of the cover define a chamber or conduit connecting the aforementioned second orifice and the one-way valve to the outside, thereby ensuring air access to the second orifice; and

[0015] - The body of the cover and the user's lips, wherein a passage in the body of the cover defines a chamber or conduit between the user's lips and the second orifice, such that when the second orifice is blocked by the user's lips, the aforementioned second orifice and the one-way valve are in communication with the outside.

[0016] Next, different construction alternatives for the cover with an air supply system that ensures air reaches the second orifice will be described.

[0017] The first alternative includes: a circumferential wall of the cap and a first surface forming a single body, the first surface including at least one first channel that at least partially surrounds the nozzle and connects to a second orifice, the first channel being connected to the circumferential wall via at least one second channel, the channels defining a conduit of the air supply system allowing air to circulate from the circumferential wall to the second orifice.

[0018] In this alternative, when the user inserts the nozzle into his or her mouth, his or her lips will not only block the second orifice, but they may also partially cover the first channel and even a portion of the second channel. However, air circulation is ensured not only by the depth of the channel communicating with the second orifice and the one-way valve, but also by the lips remaining on its surface, as the lips do not enter the channel. The lips prevent air from entering the channel through the top of the channel (which opens to the outside), but they do not prevent air from entering through the opening in the second channel located in the circumferential wall of the cap. Therefore, a chamber or conduit forming the air circulation system of the cap is formed between the lips and the channel.

[0019] In another alternative, the cap is formed of two bodies instead of one, such that a first surface (having a suction nozzle and a second orifice with a one-way valve) is arranged in the first body, and a circumferential wall is arranged in the second body. The second body has a perforated surface into which the suction nozzle is inserted, such that the second body is positioned above the first body. In this alternative, the air supply system is formed by at least one conduit or chamber located between the first surface of the first body and the second surface of the second body, and the conduit or chamber communicates with the outside of the cap through at least one third orifice arranged in the circumferential wall of the second body to allow air to enter the air supply system. Through the third orifice, air enters the space between the two bodies, thereby enabling access to the second orifice and the one-way valve, because the second surface of the second body prevents the user's lips from contacting the second orifice, as the user's lips are spaced apart from the first surface of the first body.

[0020] Regarding this final alternative, the first surface of the first body may be substantially flat or may have at least one first channel. If it has a first channel, it will connect to a second orifice and also to at least a third orifice in the circumferential wall of the second body via at least one second channel, thereby defining an air supply system that allows air to circulate from the third orifice through these channels to the second orifice.

[0021] The second surface of the second body may also be substantially smooth or may have at least one third channel. If it has said third channel, then the third channel will be connected to at least a third orifice in the circumferential wall of the second body via at least one fourth channel, said third channel at least partially overlapping the second orifice of the second body.

[0022] Based on the foregoing, a first body with or without a channel and a second body with or without a channel can be combined to realize a cover having an air supply system from the outside to a second orifice with a one-way valve.

[0023] In an alternative cover having a first body and a second body, the second surface of the second body includes, on its underside, a third channel complementary to the first channel of the first body and a fourth channel complementary to the second channel of the first body, thereby defining a conduit for an air supply system. The second and fourth channels connect to at least one third orifice in the circumferential wall, thereby allowing air to circulate from the third orifice through the conduit of the air supply system to the second orifice. Therefore, except for the area occupied by the channels defining the conduit of the air supply system, the first surface of the first body and the second surface of the second body are in contact over their entire area.

[0024] In another alternative cover having a second combination of a first body and a second body, the first body has the aforementioned channel, and the second body has a substantially smooth surface. As in the previous case, the first surface of the first body and the second surface of the second body can be in contact over their entire area, except for the area occupied by the channel defining the air supply system.

[0025] In another alternative cover having a second combination of a first body and a second body, the first body has a substantially smooth surface, and the second body has the aforementioned channel. In this case, the first surface of the first body and the second surface of the second body can also be in contact over their entire area, except for the area occupied by the channel defining the air supply system.

[0026] In another alternative configuration of the cover, the first surface of the first body and the second surface of the second body may not be in contact. In this configuration, the conduit for the air supply system is defined by the second surface of the second body, the first surface of the first body, and the circumferential wall of the second body, the second and first surfaces being spaced apart from each other, and at least one third orifice in the circumferential wall being arranged in the gap. This configuration is necessary when the surfaces of the body do not include the channel, but is optional if one or both of the surfaces include the channel.

[0027] Therefore, and based on the above, an air supply system, consisting of a main body or a passageway arranged therein, in the form of an air chamber or duct, can be determined by the following:

[0028] An air chamber or conduit in a cover formed by two bodies according to the invention, defined by a first surface of a first body, a second surface of a second body, and a circumferential wall of a second body, the first and second surfaces being spaced apart from each other to define the air chamber or conduit, which is connected to the outside of the cover through at least one third orifice in the circumferential wall. Therefore, the gap between the first surface of the first body and the second surface of the second body is greater than the height of at least the third orifice.

[0029] - An air chamber or conduit in a cover formed by two bodies according to the invention, the air chamber or conduit being defined by a first surface of a first body having at least one first channel connected to a second orifice defining the chamber and also connected via at least one second channel to at least a third orifice in a circumferential wall, thereby allowing air to circulate from the third orifice through the first and second channels to the second orifice. A conduit or chamber may also be defined if a third and fourth channel are provided in the second body.

[0030] Preferably, in this alternative, the second surface of the second body is in contact with the first upper surface of the first body over their entire area, except for the area occupied by the passage that thus defines the air chamber. In any case, the surfaces may also be separable from each other.

[0031] These channels increase the volume of the air chamber and help guide air from the third orifice to the second orifice.

[0032] - An air chamber or conduit in a cover formed by the two bodies according to the invention, defined by a second surface of a second body having a third channel complementary to a first channel of the first body and a fourth channel complementary to the first channel of the first body on its underside, these two channels defining the air chamber such that the second and fourth channels connect to at least a third orifice in a circumferential wall to allow air to circulate from the third orifice through the aforementioned complementary channels (the first and third channels and the second and fourth channels) to the second orifice. Preferably, in this alternative, the second surface of the second body contacts the first upper surface of the first body over their entire area, except for the area occupied by the channels.

[0033] The channel thus defines the air chamber, although the surfaces can also be separated from each other.

[0034] - An air duct or chamber in a cover formed of a single body according to the invention, which is defined by a channel in a first body and the user's lips on the channel.

[0035] Typically, the circumferential wall of the first body will have the required number of third orifices to ensure air enters the chamber. Preferably, four equidistant third orifices will be arranged in the circumferential wall. Similarly, the third orifices may have the same shape and size or different shapes and sizes.

[0036] The first and third channels in the first or second body of a lid consisting of two bodies, or the first channel in a lid consisting of a single body, preferably surround the mouthpiece.

[0037] In a cap consisting of two parts or bodies, the second surface of the second body may have a groove separate from the hole for inserting the nozzle. This groove is preferably aligned with a second opening on the first surface to allow air to enter without the user obstructing the groove, or to allow a protrusion that would otherwise obstruct the second opening to pass through it when the cap is not in use.

[0038] The cover may have a shroud or cap to cover the opening when it is not in use. The shroud or cap may have internal protrusions for blocking the first opening, the second opening, and the slot. In the case of a cover with two bodies, the shroud or cap is preferably attached to the second body. If the cover has only one body, the shroud or cap will be attached to that body.

[0039] The lid preferably has a coupling device for attachment to a container, specifically to an opening of the container. The coupling device is preferably integrated into the circumferential wall. More preferably, the coupling device is a thread for fitting the lid to the container, the thread being located on the circumferential wall of the lid. More preferably, the thread is located inside the circumferential wall, although it can be located outside the circumferential wall.

[0040] Preferably, the liquid discharge port is open, although it may have some type of valve, such as one made of latex or silicone, to regulate the discharge of liquid during aspiration.

[0041] To use a variant of the lid object of the present invention having two bodies, the user inserts the liquid discharge nozzle into his or her mouth and ensures that air can enter the second air inlet orifice, even in lids with an air inlet groove in the first surface (which can be blocked by the user's lips). Air enters the air chamber arranged between the two bodies constituting the lid through a third orifice in the circumferential wall of the first body. Thus, when the user draws liquid through the first orifice, air is introduced through the third orifice of the first body, reaches the air chamber, and from the air chamber reaches the second orifice, through which air is introduced into the container.

[0042] As described above, the second air inlet has a one-way valve that allows air to enter the container but prevents liquid from leaving the container. This valve is preferably constructed within a body having a second surface and is made of the same material as the body. Alternatively, it can be an element added to the second body, made of a material such as silicone or latex. The valve prevents liquid from leaving the second inlet when the user stops drawing through the first inlet and the container is rotated.

[0043] In a preferred variation (where the valve is made of the same material as the body having the second surface and integrated into the body), this material will be a rigid or semi-rigid plastic, preferably polyethylene, which has high resistance and low or zero elasticity, primarily compared to latex-type or silicone-type materials with significant elasticity. Similarly, when the cap comprises two bodies, the first body will also be made of a rigid or semi-rigid plastic, preferably polyethylene, with high resistance and low or zero elasticity, primarily compared to latex-type or silicone-type materials with significant elasticity.

[0044] As mentioned, a one-way valve or air regulator allows air to enter during the process of drawing in liquid contained in the receiver or container, but prevents liquid from flowing out when no liquid is being drawn at the first liquid discharge orifice, in which case liquid is allowed to flow out only through the orifice used for this purpose. In other words, when a user draws in and drinks through the first liquid discharge orifice, the valve opens to allow air to enter the container, making it easier to drink the liquid. When the container is compressed, a one-way valve cover allows liquid to flow out through the first liquid discharge orifice, keeps the valve closed and prevents liquid from flowing out due to the precision of the liquid applied to the valve, and prevents air from entering the container through the second air inlet orifice.

[0045] Preferably, the one-way or regulating valve described in patent application EP2743201A1 is made of the same rigid or semi-rigid material having low or zero elasticity in the solid state, similar to the remainder of the second body, and is made of a tubular, but not necessarily cylindrical, body with two ends, such that the first end contacts the bottom surface of the cap, wherein the wall of the tubular body or conduit surrounds the air inlet orifice on the bottom side of the cap. The second free end, opposite the first end, has walls that contact each other, thereby closing the tubular body, such that the cross-section of the valve body in the closed position has an approximately triangular shape. Therefore, when the cap is fitted onto the container, the tubular body is inserted into the container, such that in the resting position, the tubular body, integral with the bottom surface of the cap, is closed at its free end, and in the operating position, when a person drinks, the free end is open, allowing air to circulate towards the interior of the container, having an approximately rectangular cross-section.

[0046] The cap, primarily its first body, is essentially cylindrical and serves as the attachment point to an opening in a liquid container, which is also typically cylindrical. In any case, a shape other than cylindrical can be considered by adapting a connecting device between the first body and the container. The cap is fitted onto the container by a connecting device, preferably a threaded or pressure element, and preferably disposed on the inner surface of the cap's sidewall or circumferential wall, as described above.

[0047] The cap body is manufactured from a single mold using a single-step injection molding process. Similarly, if the second body of the cap incorporates a valve, the second body can be made of two different materials, or at least two materials, but these materials have similar properties, particularly similar rigidity, which form the single body in which the valve is incorporated. Once both bodies have been manufactured, they are joined together by inserting the nozzle of the first body through a hole in the second body.

[0048] Preferably, the cover of the present invention has a diameter of about 3.2 cm (a typical diameter in 0.33 and 0.5 liter containers containing water), and the distance between the axis of the liquid discharge orifice and the axis of the air inlet orifice is about 1.3 cm, which can vary between 1 and 1.5 cm.

[0049] The cap of the present invention is preferably applied to bottles for water or soft drinks, although it can also be used for isotonic beverages. Similarly, the cap of the present invention can also be applied to dispensers for sauces and other food products.

[0050] Preferably, the material used to manufacture the cover of the present invention is low-density polyethylene or polypropylene resin with a density between 0.85 and 1.2 g / cm³. 3 More preferably, it is between 0.9 and 0.95 g / cm³. 3 In addition, some other materials that can be used include SABIC's PP575P or PP412MN40, ISPLEN (REPSOL)'s PR280P1M or ExxonMobil's IDPE LD 104BR, as well as polymers and biocompatible materials.

[0070] With reference to the foregoing drawings, and according to the adopted reference numerals, preferred exemplary embodiments of the invention, including the components and elements described in detail below, can be observed therein. Thus, up to five preferred embodiments of the cover object of the invention are observed in the drawings.

[0071] As can be seen from the accompanying drawings, the cap of the liquid container, receiver, or bottle to which this application is subject typically includes:

[0072] - Circumferential wall (16, 106, 516) that can fit the opening of the liquid container;

[0073] - A first surface (25, 205, 525) having at least one suction nozzle (24, 204, 524) rising from the surface (25, 205, 525) and having at least one first orifice (21, 201, 521) for discharging liquid from the container; the first surface (25, 205, 525) also having at least one second orifice (22, 202, 522) for allowing air to enter the container, and the second orifice (22, 202, 522) having a one-way valve (23, 203, 523) that allows air to enter the container but prevents liquid from exiting; and

[0074] - An air supply system (40, 41, 42, 43, 44) extends from the circumferential wall (16, 106, 516) to the second orifice (22, 202, 522) to guide air from the circumferential wall (16, 106, 516) to the second orifice (22, 202, 522).

[0075] The present invention is in Figures 1 to 16 Various examples of lids comprising two main bodies, namely a first body (20, 200) and a second body (10, 100), are shown. Figure 17 and Figure 18 An exemplary embodiment with a single body (500) is shown.

[0076] Figures 1 to 16 The example in the example has a lid, where:

[0077] - The first surface (25, 205) is disposed in the first body (20, 200);

[0078] - The circumferential walls (16, 206) are arranged in the second body (10, 100), which is formed by a second surface (11, 101) having holes (13, 103) for inserting the nozzle (24, 204) of the first body (200); and

[0079] - The air supply system (40, 45) is at least one conduit (108, 109, 204, 209) located between the first surface (25, 205) of the first body (20, 200) and the second surface (11, 101) of the second body (10, 100), the at least one conduit communicating with the outside of the cover through at least one third opening (14, 104) arranged in the circumferential wall (16, 106) of the second body (10, 100) to allow air (A) to enter the air supply system (40, 45).

[0080] In these Figures 1 to 16The present invention is illustrated in up to four embodiments, wherein air chambers 40, 41, 42, 43 are arranged between the second surface 11 of the second body 10, 100 and the first surface 25, 205 of the first body 20, 200, and when the cover is attached to the container 30, the air chambers 40, 41, 42, 43, 44 are connected to the outside of the cover through third openings 14, 104 arranged in the circumferential walls 16, 106 of the first body.

[0081] More specifically, Figure 1 and Figure 3 A first embodiment of a second body 10 is shown, the second body 10 having a generally flat or smooth second surface 11 surrounded by a circumferential wall 16, the circumferential wall 16 including means (not shown) for attaching it to an opening of a container or receiver 30, the container or receiver 30 containing a liquid to be applied through the cap object of the present invention. The second surface 11 has an orifice 13 and preferably a groove 15 adjacent to the orifice 13. Similarly, the circumferential wall has at least one third orifice 14, preferably four, the third orifices being spaced apart in the circumferential wall 16. The first body may include a cover or cap 12 fitted onto the first body 11 to block the different orifices 15, 14. The cover or cap 12 may include an internal protrusion 17 that is at least partially inserted into the different orifices of the cap to block those orifices. The cover or cap 12 may include a closure device 18 complementary to the closure device 19 in the first body 11. In this example, a flange-like protrusion 18 inserted into a recess 19 is shown. The material of the second body 10 of the cover is preferably a solid rigid or semi-rigid plastic, preferably polyethylene, and although it is flexible, it is not elastic in the stated state.

[0082] Figure 2 and Figure 4The first embodiment of the first body 20 shown has a nozzle 24 exposed from a substantially flat or smooth first surface 25, and a first liquid discharge orifice 21 disposed at the free end of the nozzle 24. The first body has a second orifice 22 for air inlet, which in this example is in the form of a groove. The second air inlet 22 also has a one-way valve 23 in the bottom of the first surface 25, which faces the housing once the cap has been attached to the housing of the container or receiver 30. In this example, the valve 23 forms part of the second body 20 of the cap 1 because it is made of the same material as the cap and manufactured in the same process. The material of the first body 20 of the cap is preferably a solid rigid or semi-rigid plastic, preferably polyethylene, and although flexible, it is not elastic in the stated state. In any case, the first body 20 may also have two or more materials: at least one for the first body 20 and another for the valve, and the first body 20 may be manufactured by a single injection or two injections, provided that they allow the first body 20 to be manufactured in such a way that the components form a single body or part.

[0083] In an exemplary embodiment, the one-way valve 23 includes a tubular body forming part of a first body 20 that forms a cover, wherein the wall of a first end of the tubular body surrounds an air inlet orifice 22, and the walls of a second end of the body contact each other, thereby closing the conduit of the valve 23. Alternatively, the one-way valve may be constructed of a silicone or latex element coupled to the first body 20 and coinciding with the second orifice 22.

[0084] Figure 5 An exemplary embodiment of the cover 1 of the present invention is shown, wherein the first body 20 is coupled to the second body 10 after the suction nozzle 24 of the first body 20 is inserted into the hole 13 of the second surface 11 of the second body 10. The base of the suction nozzle 24 on the first surface of the first body 20 is fitted into the hole 13 of the second surface of the first body 10, thereby forming the cover 1. The groove 15 of the second surface 11 of the second body 10 is aligned with the second air inlet 22 on the first surface 25 of the first body 20. The groove 15 is optional.

[0085] The second body 11 of the cap 1 has a fixing device for securing to a container, receiver, or bottle 30, threads within the circumferential wall 16 of the second body 10 to fit into the neck or opening of the container, receiver, or bottle 30, and a cap or cover 12 integral with the second body 10 of the cap 1. As described above, the cap 12 may include a protrusion adapted to a liquid discharge port 21 and a protrusion 17 adapted to an air inlet port 22. In order for the protrusion 17 to accommodate the second air inlet port 22, a groove 15 needs to be provided in the first surface 11 so that the protrusion 17 can be inserted into the groove 22.

[0086] Figure 6 The illustration depicts a user drinking from a bottle or container 30 with a cap of the present invention. The cap allows the beverage within the bottle 30 to be consumed comfortably without the risk of liquid leaking out through the second air inlet 22, as it has a one-way valve. Thus, the consumer draws in through the first liquid outlet 21 of the spout 24, creating a low pressure within the container or bottle 30, which causes the one-way valve 23 to open, thus allowing air to enter the container or bottle 30. When no low pressure is created due to lack of suction, the valve 23 closes and remains closed in this state.

[0087] Figure 7 A perspective cross-sectional view of an exemplary embodiment of the cover 1 of the present invention is shown, wherein a first body 20 is connected to a second body 10. To ensure the operation of the cover 1 as described, it is necessary to ensure that while the user is aspirating through the first liquid L discharge port 21, air A reaches the second air A inlet port 22 and thus the valve 23 disposed in the first body 20 of the cover 1. The natural passage for air A to the second air A inlet port 22 is a groove 15 disposed in the first body 10, but this groove 15 can be blocked by the user's lips when the user inserts the suction nozzle 24 into his or her mouth to aspirate liquid L through the first port 21.

[0088] Therefore, in the event that the groove 15 is blocked or that the groove 15 is not provided in the first body, it is necessary to facilitate the entry of air A into the second air A inlet 22, which is achieved in the case of the third air A inlet 14 inside the cap. These third orifices 14 provide passage to the air chamber 40 when a conduit is formed between the second body 10 and the first body 20 (specifically, between the second surface 11 of the second body 10, the first surface 25 of the first body 20, and the circumferential wall 16 of the second body). Thus, as described above, the cap 1 allows the beverage inside the bottle 30 to be consumed comfortably without the risk of liquid flowing out of the bottle 30 through the second air inlet 22. When the consumer or user wishes to drink directly from the bottle 30, he or she can draw or drink from the beverage flow.

[0089] If the user draws liquid through the first liquid discharge port 21 via the nozzle or spray nozzle 23, a low pressure is generated within the bottle 30, causing the one-way valve 23 to open. This allows air A to enter the bottle as it passes through the third port 14, reaches the air chamber 40, and from there through the second port 22 to reach the interior of the bottle 30 after passing through the valve 23. The greater the suction, the larger the opening of the valve 23, the more air A enters, and therefore, the more liquid L is discharged. Conversely, the same thing happens because when there is no suction and therefore no low pressure is generated, the valve 23 closes.

[0090] If a user wishes to drink from the beverage stream, that is, directly from the stream exiting through the first liquid L outlet 21 of the cap 1, he or she may compress the bottle 30 from the outside if the bottle 30 allows, so that the valve 23 is sealed by the compression of the valve 23 by the liquid L inside the bottle 30, thereby forcing the liquid 30 out through the first liquid L outlet 21, as if the cap 1 included only a single outlet on its surface.

[0091] The above is for Figures 1 to 7 The operation of the cover object of the present invention described in the exemplary embodiments is also applicable to the following descriptions and Figures 8 to 18 Exemplary embodiments of covers 2, 3, 4, and 5.

[0092] therefore, Figure 8 and Figure 10 A second embodiment of a second body 100 of the cover object of the present invention is shown. The second body 100 has one or more third channels 109 on the underside of its second surface 101, which extend near or around the hole 103 and connect via a fourth channel 108 to a third opening 104 disposed in the circumferential wall 106 of the first body 100. If the second body 101 includes a groove 105 in its first surface 101, the third channel 109 will trace its trajectory from the groove 105 near the hole 103. The second body 100 may include a cover or cap 102, which may have a protrusion 107 depending on the opening to be blocked in the cover. The third channel 109 and the fourth channel 108 preferably have a semi-circular cross-section, although they may also be, for example, square or triangular.

[0093] Figure 9 A second exemplary embodiment of the first body 200 of the cap is shown. It includes one or more first channels 209 in the top side of a first surface 205, which preferably extend from a second air inlet 202 disposed in the first surface 205 of the first body 200 near or around the base of the nozzle 204. The first channels 209 are connected to the periphery or periphery of the first body 200 via second channels 208. The first channels 209 and the second channels 208 preferably have a semi-circular cross-section, although they may also be, for example, square or triangular.

[0094] The first bodies 20 and 200 and the second bodies 10 and 100 can be joined together without being obvious to form different covers. Sometimes, minor modifications may be needed to ensure proper connection between the two bodies. Figures 11 to 16 Cross sections of four different examples of covers 1, 2, 3, 4 formed by the connection of first bodies 20, 200 and second bodies 10, 100 are shown.

[0095] Figure 11 and Figure 12 A first exemplary embodiment is shown, which is connected to the second body 10. Figure 1 and Figure 3 First exemplary embodiment of the first subject 20 () Figure 2 and Figure 4 The cap 1 is formed. There is a fit between the periphery of the suction nozzle 24 and the hole 13 in the second body 10. Specifically, they are... Figure 7 Two cross-sections of the cover 1 are shown. In these cross-sections, the air supply system 40 can be seen in the form of a chamber or pipe arranged between a first surface 25 of the first body 20 and a second surface 11 of the second body 10, the first surface 25 and the second surface 11 being spaced apart from each other by a distance equal to or greater than the height of the third opening 14. Similarly, it can be seen how the chamber 40 communicates with the outside through the third opening 14 arranged in the second body 10, and how it communicates with the second opening 22 in the first body 20, and thus with the one-way valve 23 formed within the first body 20 itself. In this cover 1, the second body 20 has a groove 15 aligned with the second opening 22, but the groove 15 may not be in the second body, or conversely, it may be in the second body but not aligned with the second opening 22.

[0096] Figure 13 and Figure 14 A second exemplary embodiment consisting of a first body 200 is shown. Figure 9 ) and the second exemplary embodiment of the second body 100 ( Figure 8 and Figure 10The cover 2 is formed by the suction nozzle 204. There is a fit between the nozzle 204 and the hole 103 in the second body 10. In the cross-section, the first channel 209 and the second channel 208 of the first body 200 can be seen facing the third channel 109 and the fourth channel 108 of the second body 100, respectively. The attachment of the first channel 209 and the third channel 109, and the attachment of the second channel 208 and the fourth channel 108, form the air supply system 41 of the cover 2, specifically a conduit or chamber connecting the exterior of the cover 2 to the second opening 202 of the first body 200. The second channel 208 and the fourth channel 108 communicate with the exterior through the third opening 104 formed in the circumferential wall 106 of the second body 100. In this cover 2, the first surface 205 of the first body 200 contacts the second surface 101 of the first body 100 on its entire surface, except where the channels 208, 209, 108, 109 are located. A supply system 41, formed by pipes (which in turn are formed by channels 208, 209, 108, 109), guides air from a third orifice 104 to a second orifice 202 of the first body 200. A one-way valve 203, formed within the first body 200 itself, is located at the second orifice 202. In this cover 2, the second body 200 has a groove 105 aligned with the second orifice 202, but the groove 105 may not be in the second body, or conversely, it may be in the second body but not aligned with the second orifice 202.

[0097] Figure 15 A first exemplary embodiment of the second body 10 is shown. Figure 1 and Figure 3 A second exemplary embodiment of the first body 200 connected ( Figure 9 A cover 3 is formed. In this cover 3, the air supply system 42 for the second orifice 202 and the one-way valve 203 (not shown) is formed by a first channel 209 and a second channel 208. The first channel 209 and the second channel 208 are formed in the first surface 205 of the first body 200, which is coupled to the second surface 11 of the second body 10. The first surface 205 of the first body 200, except where the channels 209 and 208 meet, contacts the entire second surface 11 of the second body 10. The cross-sections of the channels 209 and 208 can be varied according to the need for airflow to circulate through the channels 209 and 208. The second channel 208 is aligned with the third orifice 14 of the first body to allow air to enter from the outside of the cover 3 into the second orifice 202 and the valve 203 of the first body 200.

[0098] Figure 16 A second exemplary embodiment of the second body 100 is shown. Figure 8 and Figure 10 First exemplary embodiment of the first body 20 connected () Figure 2 and Figure 4 A cover 4 is formed. In this cover 4, the air supply system 43 for the second orifice 22 and the one-way valve 23 (not shown) is formed by a third channel 109 and a fourth channel 108, which are formed in the second surface 25 of the second body 100, which is coupled to the first surface 25 of the first body 20. The first surface 25 of the first body 20, except where the channels 109 and 108 meet, contacts the entire second surface 101 of the second body 100. The cross-sections of the channels 109 and 108 can vary according to the need for airflow to circulate through the channels 109 and 108. The fourth channel 108 is an extension of the third orifice 104 toward the interior of the second body 100, allowing air to enter from the outside of the cover 4 into the second orifice 22 and the valve 23 of the first body 20, as the third channel 109 passes over the second orifice 22, thereby communicating with the second orifice 22.

[0099] exist Figures 11 to 16 In the cross-section, the covers or caps 12, 102 integral with the second bodies 10, 100 are not shown. Similarly, the cross-sections of the channels are shown as semicircles, but they may have other cross-sections, which may have variable depths and widths as needed.

[0100] Figure 17 and Figure 18Another exemplary embodiment of the cover 5 is shown. Unlike the previous embodiments, the cover 5 is formed of a single body 500 having a circumferential wall 516 and a first surface 525, the circumferential wall 516 being fitted into an opening of a liquid container. The surface 525 has a suction nozzle 524 rising from the surface 525, having a first orifice 521 for liquid discharge, and the surface 525 also has a second orifice 522 for air to enter the container. The second orifice 522 has a one-way valve 523 that allows air to enter the container but prevents liquid from flowing out. The cover has an air supply system 44 extending from the circumferential wall 516 to the second orifice 522 to guide air from the circumferential wall 516 to the second orifice 522. Specifically, the air supply system 44 is formed by a first channel 509 and a second channel 508. The first channel 509 surrounds the mouthpiece 524, and the second channel 508 communicates the first channel 509 with a circumferential wall 516, specifically with an opening or aperture 504 formed in the wall 516. The opening or aperture 504 has a cross-section larger than that of the second channel 508 to facilitate air entry into the supply system 44. In the cover 5, when the user inserts the mouthpiece 524 into his or her mouth for drinking, his or her lips will likely cover both the first channel 509 and the second air inlet aperture 522, such that the air supply system 44 will be formed by a conduit formed by the user's lips and the bottom of the channels 509 and 508, and this conduit will have sufficient depth to ensure air circulation from the aperture or opening 504 and the second aperture 524 through the second channel 508 and the first channel 509. The cover 5 preferably has a second channel 508 communicating with the first channel 509. The cover 5 also shows a cover or cap 512 integral with the body 500 of the cover, the cover or cap 512 having an internal protrusion 517 for blocking the first orifice 521 and the second orifice 522 located in the nozzle 524.
