[0003] Liquid dispensing containers are used in a wide range of consumer, commercial, and industrial applications, and users increasingly expect these containers to deliver liquids smoothly, cleanly, and predictably. A persistent challenge in many conventional containers is the interruption of flow caused by “glugging,” an effect produced when liquid leaving the container alternates with air entering through the same opening. This alternating flow can generate sudden surges, turbulence, or splashing, which may result in spills, dosing inconsistency, or agitation of foam-sensitive liquids.

[0004] To address these issues, prior designs have incorporated features such as passive vents, auxiliary openings, mechanical valves, or complex air-management channels. However, these solutions often introduce drawbacks, including higher manufacturing cost, increased component complexity, susceptibility to clogging, and cleaning or maintenance difficulties. Some venting systems perform inconsistently across varying liquid levels, while others require precise manufacturing tolerances that can limit scalability.

[0032] The following detailed description sets forth various exemplary embodiments of the disclosed liquid-dispensing container. These embodiments are presented for purposes of illustration and are not intended to limit the scope of the invention as defined by the claims. Variations in form, material selection, manufacturing technique, and configuration may be made without departing from the spirit or scope of the invention.

[0033] The present detailed description provides illustrative embodiments of the disclosed subject matter, which pertains to the field of liquid dispensing technologies, particularly vacuum-assisted containers designed to enhance controlled liquid flow. The disclosed subject matter addresses common challenges in liquid dispensing, such as glugging, spillage, and inconsistent flow, by incorporating innovative mechanisms that facilitate smooth and predictable liquid dispensing. While specific embodiments, configurations, and methods are described herein, these are provided solely for illustrative purposes and are not intended to limit the scope of the disclosed subject matter.

[0034] Certain details, such as conventional manufacturing techniques or standard material properties, may be omitted where they are well-known to those skilled in the art. Furthermore, the described subject matter allows for various modifications, substitutions, and rearrangements of components or methods that achieve the same or similar functionality as outlined. Such variations are considered within the scope defined by the claims, and the principles disclosed herein are intended to be broadly applicable across a range of implementations.

[0035] As used herein, the terms “about” and “approximately” are intended to encompass variations of ±10% from the stated numerical value, unless the context clearly dictates otherwise. For example, a dimension, volume, or ratio recited as “about X” or “approximately X” includes values within 10% above or below X. Such terms are used to account for normal manufacturing tolerances, measurement variations, and acceptable functional equivalents.

[0036] In the domain of liquid dispensing containers, a persistent challenge has been ensuring smooth and controlled liquid flow during use. Conventional containers often suffer from issues such as glugging, spillage, and inconsistent flow, which can lead to user dissatisfaction, product wastage, and compromised functionality. Glugging, in particular, results from the alternating intake of air and liquid during pouring, causing interruptions in flow and sudden surges that can lead to splashes or spills. Additionally, turbulence within the container can agitate the liquid, creating foaming or other undesirable effects, especially for carbonated or sensitive liquids. Existing solutions, such as passive venting channels, mechanical valves, or complex sealing mechanisms, often fail to address these issues effectively. These approaches may introduce additional manufacturing complexity, higher costs, or maintenance challenges, such as clogging or difficulty in cleaning. As a result, there remains a need for a streamlined, user-friendly solution that ensures reliable, controlled liquid dispensing while maintaining ease of use and manufacturability.

[0037] The present system addresses these limitations by introducing a vacuum-assisted liquid dispensing container that leverages a venting tube system to facilitate smooth and predictable liquid flow. The described concept incorporates a venting tube with a lower section open to the chamber's lower portion and an upper section extending through the container wall near the upper surface. This venting tube allows air to flow into the chamber during dispensing, thereby preventing glugging and ensuring a steady, laminar flow of liquid. A breakaway tab seals the upper section of the venting tube during storage, ensuring secure containment of the liquid. Upon removal of the tab, the venting tube is opened, enabling air ingress to balance the pressure within the chamber as the container is inverted. This vacuum effect eliminates flow interruptions and minimizes turbulence, enhancing the user experience and reducing waste. The dispensing port is designed with an optimized diameter to further reduce turbulence and spillage, while the venting tube's smaller diameter ensures efficient air intake without compromising liquid flow.

[0038] By integrating these features, the described system provides a practical and hygienic solution for controlled liquid dispensing across various applications, including beverages, cleaning solutions, and chemical reagents. The resealable breakaway tab adds versatility, allowing the container to be securely closed after partial use, while the ergonomic design ensures ease of operation. This approach not only addresses the shortcomings of existing solutions but also offers a scalable and cost-effective option suitable for both consumer and industrial use cases.

[0052] Venting Passageway—The air flow path created within the venting tube, enabling air to enter the chamber and balance pressure during liquid dispensing.

[0053] Upper Section of Venting Tube—The portion of the venting tube that extends through the container wall near the upper surface and is sealed by the breakaway tab during storage.

[0054] Lower Section of Venting Tube—The portion of the venting tube that is open to the lower chamber portion, facilitating air intake during dispensing.

[0055] Complementary Engagement Structures—Features such as threading, ridges, grooves, snap-fit mechanisms, or press-fit interfaces that enable secure resealing of the breakaway tab to the venting tube after removal.

[0056] Capacity—The volume of liquid the chamber is designed to hold, typically specified as approximately 200 milliliters for individual serving sizes, though other sizes are contemplated.

[0057] Foaming—The formation of bubbles or froth in the liquid due to turbulence or agitation, which is undesirable in many applications. The container design minimizes foaming during dispensing.

[0058] User Interaction—The manner in which a user engages with the container, including removing the breakaway tab, inverting the container, and dispensing liquid through the dispensing port. The design prioritizes ease of use and controlled dispensing.

[0059] In one embodiment, the liquid dispensing container features a cylindrical body with a chamber designed to hold approximately 200 milliliters of liquid, making the container suitable for single-serving beverages such as cocktails, wine, or soft drinks. The dispensing port may have an internal diameter of about 18 millimeters to promote smooth liquid flow and reduce turbulence during dispensing. The air-admission passage includes a conduit with an internal diameter approximately one-third the size of the dispensing port, enhancing the balance between air intake and liquid flow. The external end of the conduit extends through the upper surface of the container body and is sealed by a removable closure member, which may include an indent for convenient gripping during removal. In another embodiment, the closure member is resealable, featuring complementary engagement structures such as threading, ridges, grooves, snap-fit features, or a press-fit interface, enabling the container to be securely resealed after partial use. The container may also include a removable cap to seal the dispensing port, helping to ensure the liquid remains uncontaminated during storage. In yet another embodiment, the container body may take on alternative shapes, such as a flask, sphere, or rectangular prism, to accommodate different aesthetic preferences or functional requirements. The chamber's capacity can vary, with larger or smaller sizes considered for applications ranging from beverage dispensing to industrial liquids like cleaning solutions or chemicals. The venting tube may be positioned to draw air into the lower portion of the chamber when the container is inverted, creating a vacuum effect that supports smooth liquid flow without glugging or spillage.

[0060] The liquid dispensing container incorporates a chamber for holding liquid, a dispensing port, and an air-admission passage with a conduit that facilitates air flow into the lower portion of the chamber during dispensing. The removable closure member seals the external end of the conduit during storage and is frangibly removable to open the air-admission passage.

[0061] The conduit physically connects the lower portion of the chamber to the exterior of the container, enabling air to enter the chamber during dispensing. This arrangement prevents the formation of a vacuum within the chamber, which would otherwise interrupt liquid flow.

[0062] The frangibly removable closure member ensures secure storage by sealing the conduit, preventing contamination or leakage during transport or storage. Upon removal, the closure member allows air ingress, balancing the pressure inside the chamber and enabling smooth, uninterrupted liquid flow through the dispensing port.

[0063] Compared to conventional containers that rely on passive venting or complex mechanical valves, this design simplifies the air-admission mechanism while maintaining reliable performance. The vacuum effect created during dispensing minimizes glugging and turbulence, ensuring a steady and controlled liquid flow. Practical applications include dispensing beverages, cleaning solutions, or chemical reagents, where consistent flow and reduced spillage are important.

[0064] In one embodiment, the method of dispensing liquid involves providing a container with a chamber for holding liquid, a dispensing port, and an air-admission passage including a conduit with an internal end in fluid communication with the lower portion of the chamber and an external end sealed by a frangibly removable closure member. The method includes opening the external end of the conduit by removing the closure member, optionally by grasping an indent formed in the closure member, and then inverting the container so that the dispensing port faces downward. As the liquid is dispensed through the port, air is admitted from the exterior through the conduit into the lower portion of the chamber, thereby reducing interruption of liquid flow and preventing glugging. In another embodiment, the method further includes removing a removable cap from the dispensing port prior to dispensing. The dispensing port may have an internal diameter of about 18 millimeters, and the conduit may have an internal diameter that is about one-third of the dispensing port's diameter. The chamber may have a capacity of about 200 milliliters, but other sizes are contemplated. After dispensing, the closure member may be reattached to reseal the external end of the conduit, using complementary engagement structures such as threads, ridges, grooves, snap-fit features, or a press-fit interface, thereby enabling secure storage of any remaining liquid.

[0065] The method facilitates smooth and uninterrupted liquid dispensing by admitting air into the chamber through the conduit during dispensing. This arrangement prevents the formation of a vacuum within the chamber, which would otherwise interrupt liquid flow. By ensuring consistent air ingress, the method eliminates glugging and flow interruptions, enhancing reliability and user experience during liquid dispensing.

[0066] Inverting the container ensures that the dispensing port is positioned downward, allowing gravity to assist in liquid flow while the conduit admits air into the chamber. This orientation optimizes the vacuum effect, balancing internal pressure and enabling a steady, laminar flow of liquid. The design minimizes turbulence and spillage, making the dispensing process more controlled and efficient.

[0002] The present disclosure pertains to liquid dispensing technologies and, more specifically, to vacuum-assisted containers configured to improve controlled liquid flow and reduce interruptions during dispensing.BACKGROUND

[0003] Liquid dispensing containers are used in a wide range of consumer, commercial, and industrial applications, and users increasingly expect these containers to deliver liquids smoothly, cleanly, and predictably. A persistent challenge in many conventional containers is the interruption of flow caused by “glugging,” an effect produced when liquid leaving the container alternates with air entering through the same opening. This alternating flow can generate sudden surges, turbulence, or splashing, which may result in spills, dosing inconsistency, or agitation of foam-sensitive liquids.

[0004] To address these issues, prior designs have incorporated features such as passive vents, auxiliary openings, mechanical valves, or complex air-management channels. However, these solutions often introduce drawbacks, including higher manufacturing cost, increased component complexity, susceptibility to clogging, and cleaning or maintenance difficulties. Some venting systems perform inconsistently across varying liquid levels, while others require precise manufacturing tolerances that can limit scalability.

[0005] Accordingly, there remains a need for a liquid-dispensing container that enables controlled, uninterrupted flow while maintaining simplicity, manufacturability, and hygienic operation. Desirable characteristics include a venting mechanism that reliably admits air during dispensing, a container structure that minimizes turbulence and spillage, and components that remain easy to use, cost-effective to produce, and compatible with a variety of liquid types. The present disclosure provides such a solution.SUMMARY

[0032] The following detailed description sets forth various exemplary embodiments of the disclosed liquid-dispensing container. These embodiments are presented for purposes of illustration and are not intended to limit the scope of the invention as defined by the claims. Variations in form, material selection, manufacturing technique, and configuration may be made without departing from the spirit or scope of the invention.

[0033] The present detailed description provides illustrative embodiments of the disclosed subject matter, which pertains to the field of liquid dispensing technologies, particularly vacuum-assisted containers designed to enhance controlled liquid flow. The disclosed subject matter addresses common challenges in liquid dispensing, such as glugging, spillage, and inconsistent flow, by incorporating innovative mechanisms that facilitate smooth and predictable liquid dispensing. While specific embodiments, configurations, and methods are described herein, these are provided solely for illustrative purposes and are not intended to limit the scope of the disclosed subject matter.

[0034] Certain details, such as conventional manufacturing techniques or standard material properties, may be omitted where they are well-known to those skilled in the art. Furthermore, the described subject matter allows for various modifications, substitutions, and rearrangements of components or methods that achieve the same or similar functionality as outlined. Such variations are considered within the scope defined by the claims, and the principles disclosed herein are intended to be broadly applicable across a range of implementations.

[0035] As used herein, the terms “about” and “approximately” are intended to encompass variations of ±10% from the stated numerical value, unless the context clearly dictates otherwise. For example, a dimension, volume, or ratio recited as “about X” or “approximately X” includes values within 10% above or below X. Such terms are used to account for normal manufacturing tolerances, measurement variations, and acceptable functional equivalents.

[0036] In the domain of liquid dispensing containers, a persistent challenge has been ensuring smooth and controlled liquid flow during use. Conventional containers often suffer from issues such as glugging, spillage, and inconsistent flow, which can lead to user dissatisfaction, product wastage, and compromised functionality. Glugging, in particular, results from the alternating intake of air and liquid during pouring, causing interruptions in flow and sudden surges that can lead to splashes or spills. Additionally, turbulence within the container can agitate the liquid, creating foaming or other undesirable effects, especially for carbonated or sensitive liquids. Existing solutions, such as passive venting channels, mechanical valves, or complex sealing mechanisms, often fail to address these issues effectively. These approaches may introduce additional manufacturing complexity, higher costs, or maintenance challenges, such as clogging or difficulty in cleaning. As a result, there remains a need for a streamlined, user-friendly solution that ensures reliable, controlled liquid dispensing while maintaining ease of use and manufacturability.

[0037] The present system addresses these limitations by introducing a vacuum-assisted liquid dispensing container that leverages a venting tube system to facilitate smooth and predictable liquid flow. The described concept incorporates a venting tube with a lower section open to the chamber's lower portion and an upper section extending through the container wall near the upper surface. This venting tube allows air to flow into the chamber during dispensing, thereby preventing glugging and ensuring a steady, laminar flow of liquid. A breakaway tab seals the upper section of the venting tube during storage, ensuring secure containment of the liquid. Upon removal of the tab, the venting tube is opened, enabling air ingress to balance the pressure within the chamber as the container is inverted. This vacuum effect eliminates flow interruptions and minimizes turbulence, enhancing the user experience and reducing waste. The dispensing port is designed with an optimized diameter to further reduce turbulence and spillage, while the venting tube's smaller diameter ensures efficient air intake without compromising liquid flow.

[0038] By integrating these features, the described system provides a practical and hygienic solution for controlled liquid dispensing across various applications, including beverages, cleaning solutions, and chemical reagents. The resealable breakaway tab adds versatility, allowing the container to be securely closed after partial use, while the ergonomic design ensures ease of operation. This approach not only addresses the shortcomings of existing solutions but also offers a scalable and cost-effective option suitable for both consumer and industrial use cases.

[0064] In one embodiment, the method of dispensing liquid involves providing a container with a chamber for holding liquid, a dispensing port, and an air-admission passage including a conduit with an internal end in fluid communication with the lower portion of the chamber and an external end sealed by a frangibly removable closure member. The method includes opening the external end of the conduit by removing the closure member, optionally by grasping an indent formed in the closure member, and then inverting the container so that the dispensing port faces downward. As the liquid is dispensed through the port, air is admitted from the exterior through the conduit into the lower portion of the chamber, thereby reducing interruption of liquid flow and preventing glugging. In another embodiment, the method further includes removing a removable cap from the dispensing port prior to dispensing. The dispensing port may have an internal diameter of about 18 millimeters, and the conduit may have an internal diameter that is about one-third of the dispensing port's diameter. The chamber may have a capacity of about 200 milliliters, but other sizes are contemplated. After dispensing, the closure member may be reattached to reseal the external end of the conduit, using complementary engagement structures such as threads, ridges, grooves, snap-fit features, or a press-fit interface, thereby enabling secure storage of any remaining liquid.

[0065] The method facilitates smooth and uninterrupted liquid dispensing by admitting air into the chamber through the conduit during dispensing. This arrangement prevents the formation of a vacuum within the chamber, which would otherwise interrupt liquid flow. By ensuring consistent air ingress, the method eliminates glugging and flow interruptions, enhancing reliability and user experience during liquid dispensing.

[0066] Inverting the container ensures that the dispensing port is positioned downward, allowing gravity to assist in liquid flow while the conduit admits air into the chamber. This orientation optimizes the vacuum effect, balancing internal pressure and enabling a steady, laminar flow of liquid. The design minimizes turbulence and spillage, making the dispensing process more controlled and efficient.
