Specification

Description:FIELD OF THE INVENTION:
The field of the present invention pertains to infant feeding solutions, specifically to an improved feeding bottle equipped with an airflow regulator. This invention focuses on minimizing air ingestion by infants during feeding, aiming to reduce digestive discomfort and colic through regulated airflow and pressure stabilization.

BACKGROUD OF THE INVENTION:
Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
Infant feeding bottles have evolved significantly over the years, yet air ingestion remains a persistent issue that can lead to discomfort in babies. Many infants experience colic, gas, and spit-ups due to the unintentional ingestion of air while feeding. The causes of these issues often trace back to traditional bottle designs, which allow air to mix with the liquid being consumed, leading to the ingestion of air bubbles. When infants swallow these bubbles, it can cause bloating, pain, and crying episodes, which distress both the infant and the caregiver. To address these challenges, various bottles on the market claim to offer anti-colic features; however, they often lack consistency and effectiveness in minimizing air exposure and controlling airflow.
The traditional feeding bottle consists of a simple structure with a nipple at the top for liquid flow and a cap or base to hold the liquid. Although some modern designs include vents or additional components meant to alleviate air intake, these additions can be complicated to assemble, clean, and maintain. Furthermore, these anti-colic bottle designs may still allow small amounts of air to enter, which, although reduced, does not entirely solve the issue for infants who are particularly sensitive to any air ingestion. These bottles can be challenging for parents to use as they require meticulous assembly and precise handling to function as intended. In addition, some designs are complex enough that they can lead to accidental misuse, causing frustration for parents and reducing the bottles' efficacy.
In recent years, healthcare professionals and researchers have emphasized the importance of reducing air ingestion during feeding due to its potential impact on an infant's developing digestive system. Excessive gas buildup, resulting from air ingestion, can interfere with the baby's natural digestion and may contribute to other digestive issues later in life. It has become increasingly clear that an effective solution requires a feeding bottle design that can seamlessly regulate airflow without exposing the infant to any air within the liquid compartment. Current bottles on the market often rely on narrow vents or one-way valves to allow air in as the liquid is consumed; however, these features can be susceptible to clogging and may allow traces of air to mix with the liquid.
Traditional anti-colic bottles also present challenges in terms of maintenance and usability. For parents, a crucial aspect of feeding bottle selection is ease of cleaning and assembly. Bottles with multiple parts are harder to clean thoroughly, especially when components such as valves or air vents are small or intricately designed. The cleaning process becomes critical, as inadequate cleaning can lead to bacterial buildup, posing additional health risks to the infant. Furthermore, when a bottle has too many parts, there is a higher likelihood of misplacing essential components, which can compromise the bottle's performance. There is, therefore, a need for an improved feeding bottle that not only reduces air ingestion but also simplifies assembly, cleaning, and overall usability for caregivers.
Studies show that feeding experiences can significantly affect the physical and emotional bond between parents and infants. If a feeding bottle design leads to discomfort, gas, or colic, it can increase stress levels for both the child and the caregiver. A streamlined bottle with a reliable airflow regulation system can contribute to a more comfortable feeding experience, promoting bonding by reducing the potential for post-feeding discomfort. An improved bottle design that incorporates an effective airflow regulation mechanism will contribute positively to this experience by enabling the infant to feed with minimal air ingestion and reduced risk of colic. This can provide peace of mind to parents, knowing that their infant's feeding process is safer and more comfortable.
Many of the existing solutions focus on minimizing air at the top of the liquid compartment, but few address the complete separation of air from the liquid itself. By designing a feeding bottle that features a well-placed, controlled airflow regulator, it becomes possible to prevent air from mixing with the liquid, reducing the chances of ingestion even further. This separation requires a specific design that directs air away from the liquid chamber and introduces it only when necessary, ensuring that the pressure within the bottle remains stable as the liquid level decreases. This approach not only improves feeding comfort but also supports infants with heightened sensitivity to air ingestion.
In addition to functionality, the design of a feeding bottle must consider the various conditions under which it will be used. For instance, some infants may be fed in reclining positions, making it essential that the bottle's airflow mechanism functions consistently regardless of angle or orientation. Many of the current anti-colic bottles fail to address this, as they only work effectively in specific positions. By integrating an advanced airflow regulator that operates consistently in multiple orientations, an improved feeding bottle design can offer greater flexibility and effectiveness. This is particularly useful for parents who may need to feed their infants in different environments or positions, such as in a car seat, stroller, or reclined position during late-night feedings.
The material selection for such a bottle design is also of great importance. High-quality, BPA-free materials ensure the bottle is safe for infants, resistant to wear, and durable enough to withstand repeated cleaning and sterilization processes. A well-engineered bottle that incorporates safe materials and minimizes unnecessary complexity can significantly ease the feeding process for caregivers. Many anti-colic bottles made from plastic or silicone components may wear down over time, particularly in areas with valves or vents, affecting their functionality. The improved design must prioritize durability to withstand the frequent and sometimes rigorous cleaning that is essential for infant hygiene.
With an improved feeding bottle equipped with an effective airflow regulation mechanism, caregivers can have greater confidence in providing a comfortable feeding experience that supports healthy digestion and reduces discomfort. This innovation in feeding bottle technology seeks to bridge the gap between simplicity and effectiveness, aiming to meet the needs of both infants and caregivers. By reducing air ingestion and potential colic symptoms, this feeding bottle can be a valuable tool in promoting both physical comfort for the infant and emotional well-being for the caregiver. Through a design that addresses common challenges in current anti-colic bottles, this improved feeding bottle with an airflow regulator can offer a practical, safe, and effective solution for modern infant care.

With reference to FIG. 1, in an embodiment of the present invention, the present invention relates to an improved feeding bottle (100) that is designed to minimize air ingestion during feeding, addressing a significant issue in infant feeding systems that often leads to digestive discomfort, including gas, bloating, and colic in infants. This feeding bottle (100) incorporates an innovative airflow regulator valve (20) near its base, which is specifically positioned and configured to control the entry of air into the bottle to maintain consistent internal pressure without allowing air to mix with the liquid. The primary function of the airflow regulator valve (20) is to allow air into the bottle only when suction is applied by the infant. By preventing the air from entering the liquid chamber during times of no suction, this valve contributes to a seamless, steady feeding experience that reduces the infant's risk of ingesting air along with the liquid.
The dual-chamber structure (40) within the feeding bottle (100) is another crucial aspect of the invention. The structure is divided into a first chamber (42) that holds the liquid, and a second chamber (44) configured for controlled airflow. This dual-chamber design effectively separates air from the liquid, ensuring that any air entering the bottle through the airflow regulator valve (20) is directed away from the liquid chamber (42). This design reduces the likelihood of air mixing with the liquid, which is a common issue in traditional feeding bottles and a significant contributor to air ingestion by infants. By separating the airflow and liquid chambers, this design allows for a more comfortable feeding experience and promotes better digestive health for the infant, who can feed without the discomfort associated with swallowed air.
The nipple assembly (60) of the feeding bottle (100) is connected to the bottle in a way that allows smooth and controlled liquid flow while maintaining the air separation achieved by the airflow regulator valve (20). This assembly includes design features that ensure that the liquid flows at a steady rate into the nipple without allowing air to disrupt the flow. This setup is beneficial as it supports a natural feeding rhythm, aligning with the infant's natural suckling patterns. The nipple assembly (60) has been carefully engineered to work with the airflow regulator valve (20) and dual-chamber structure (40), allowing the feeding process to remain smooth, even under varying conditions of suction and bottle orientation. This design enhances the overall experience by providing a consistent liquid flow, reducing the need for the infant to exert extra suction force, which can be tiring and uncomfortable for the infant during prolonged feeding.
The body (80) of the feeding bottle (100) is constructed from medical-grade, BPA-free materials, ensuring that it is both safe for infant use and durable for long-term performance. This BPA-free body (80) is formed from flexible, non-toxic materials that withstand various sterilization methods, including steam and chemical sterilization. This durability is vital for maintaining hygiene standards, as infant feeding bottles require frequent cleaning and sterilization. Additionally, the high-quality material selection ensures that the body (80) can endure repeated sterilization cycles without degradation, maintaining the feeding bottle's performance and safety over time. The use of medical-grade materials also addresses potential health concerns, as these materials are hypoallergenic and resistant to wear, ensuring a safe feeding environment for infants.
To enhance caregiver comfort and usability, the feeding bottle (100) features an ergonomic design that facilitates easy handling. This ergonomic structure ensures consistent performance of the airflow regulation system, regardless of the angle or orientation in which the bottle is held. Infants are often fed in various positions, and this design accommodates all angles, allowing caregivers to feed the infant comfortably without compromising the functionality of the airflow regulator valve (20) or dual-chamber structure (40). This feature is particularly valuable for caregivers who may need to feed the infant in different settings, such as reclining, upright, or even in a semi-horizontal position. The ergonomic design thus supports both the infant and caregiver by ensuring the bottle functions effectively across a range of feeding scenarios, reducing stress for both parties.
In one embodiment, the airflow regulator valve (20) of the feeding bottle (100) includes a mechanism that allows for adjustment of the air entry rate based on the infant's sucking strength. This customizable airflow control allows caregivers to adapt the feeding bottle to the specific needs of their infant, as some infants may require a slightly different airflow to maintain comfort during feeding. The adjustable airflow regulator enables personalized feeding experiences, providing an optimal balance of liquid and air control. This feature is especially beneficial for infants with varying sucking strengths or for those with digestive sensitivities, as it allows for tailored adjustments to promote a more comfortable and efficient feeding process.
A protective sealing feature around the airflow regulator valve (20) further enhances the functionality and hygiene of the feeding bottle (100). This sealing feature prevents liquid leakage, ensuring that the integrity of the separation between the liquid and airflow chambers is maintained throughout the feeding process. Leakage in traditional bottles can lead to inconsistent liquid flow and diminished air separation, ultimately impacting the infant's feeding experience. By incorporating a protective seal, the present invention preserves the effectiveness of the dual-chamber structure (40) and airflow regulator valve (20), ensuring that the infant receives a smooth and uninterrupted flow of liquid without air contamination.
The dual-chamber structure (40) also serves a crucial function in reducing colic and other digestive discomforts associated with air ingestion. By keeping the air separate from the liquid in the first chamber (42), the feeding bottle (100) minimizes the risk of air ingestion, which is known to contribute to digestive distress in infants. The dual-chamber design is particularly advantageous for infants who are more sensitive to air ingestion, as it creates a feeding environment that closely mimics the natural feeding experience of breastfeeding, where minimal air is ingested. This structure thus offers a practical solution for caregivers seeking to provide an improved feeding experience, reducing the likelihood of colic and enhancing the infant's overall comfort.
The body (80) of the feeding bottle (100) is designed with a low-weight configuration, optimizing it for prolonged use. This lightweight construction helps reduce fatigue for caregivers during extended feeding sessions, making it easier to maintain a stable position while holding the bottle. The low weight is especially useful for caregivers who may experience discomfort when holding heavier bottles for long periods, thus improving the usability of the invention in everyday feeding routines. The lightweight body, combined with the ergonomic design, contributes to an overall enhanced user experience, ensuring that the bottle is both easy to handle and functional for extended feeding sessions.
In operation, the feeding bottle (100) offers a straightforward and intuitive experience for caregivers. The caregiver fills the first chamber (42) with the desired liquid, ensuring that the dual-chamber structure (40) maintains the necessary separation between the liquid and airflow chambers. As the infant begins to suck on the nipple assembly (60), the airflow regulator valve (20) allows a controlled amount of air to enter the second chamber (44) only when suction is applied. This controlled entry of air equalizes the pressure within the bottle, facilitating a smooth flow of liquid into the nipple assembly (60) without causing the liquid to mix with air. Once the feeding session is complete, the feeding bottle (100) can be disassembled for cleaning and sterilization, with each component designed to withstand rigorous hygiene practices.
Through its innovative combination of an airflow regulator valve (20), dual-chamber structure (40), ergonomic design, and medical-grade materials, this improved feeding bottle (100) offers a unique solution to common challenges in infant feeding. By minimizing air ingestion and enhancing the comfort of both infants and caregivers, this invention represents a substantial improvement in infant feeding technology, offering a reliable, safe, and effective option for managing infant feeding with reduced risk of colic and digestive discomfort. The feeding bottle (100) thus addresses a critical need in infant care, providing a practical and user-friendly solution that promotes healthy feeding practices and supports the well-being of infants and their caregivers.

The working of the improved feeding bottle with an airflow regulator (100) is designed to minimize air ingestion during feeding, thereby reducing the risk of colic and other digestive discomforts in infants. This process begins with the user filling the bottle's first chamber (42) with liquid, typically milk or formula, while ensuring that the airflow and liquid remain separated by the dual-chamber structure (40). The dual-chamber system is essential as it creates two distinct areas: the first chamber (42) that holds the liquid and the second chamber (44) designated for airflow. This separation prevents air from mixing with the liquid, a significant cause of air ingestion in traditional feeding bottles.
When feeding starts, the infant applies suction to the nipple assembly (60). This suction is detected by the airflow regulator valve (20), positioned near the base of the bottle, which opens to allow air to enter the second chamber (44) only as needed to equalize pressure inside the bottle. The valve (20) has been engineered to only activate during suction, preventing air from inadvertently entering the liquid chamber (42) when the bottle is not in use. By regulating air intake in response to the infant's natural suckling action, this airflow control mechanism ensures that the liquid flows smoothly into the nipple assembly (60) without being disrupted by unwanted air bubbles.
The nipple assembly (60) is constructed to allow a steady flow of liquid, maintaining a natural rhythm consistent with breastfeeding. The design supports a gradual and controlled liquid release, enabling infants to feed comfortably without experiencing the sudden rush of liquid that can happen with traditional bottles. The coordinated interaction between the nipple assembly (60), the dual-chamber structure (40), and the airflow regulator valve (20) allows the infant to feed without exerting extra suction effort, thus preventing fatigue during longer feeding sessions and ensuring an even flow of liquid.
Throughout the feeding process, the dual-chamber structure (40) effectively maintains air separation from the liquid, creating a vacuum-like environment that supports a continuous flow without air contamination. This setup reduces the risk of colic by limiting the amount of air the infant could potentially ingest. If the suction strength varies, the airflow regulator valve (20) adjusts accordingly, allowing more or less air into the second chamber (44) as needed to balance pressure, thus ensuring the liquid in the first chamber (42) flows smoothly into the nipple without interruption.
After feeding, the bottle can be disassembled for cleaning and sterilization. The medical-grade, BPA-free body (80) and all components are designed to withstand multiple sterilization methods, such as steam or chemical sterilization, ensuring that the bottle remains hygienic and safe for repeated use. The protective sealing feature around the airflow regulator (20) prevents liquid from entering the second chamber (44) or the valve system during cleaning, thus preserving the device's longevity and functionality.
The combination of the airflow regulator valve (20), dual-chamber structure (40), and nipple assembly (60) allows the improved feeding bottle (100) to provide a consistent and natural feeding experience. By maintaining the separation of air and liquid, the bottle effectively minimizes air ingestion, reducing the risk of colic and ensuring a more comfortable feeding experience for infants, all while being user-friendly and durable for caregivers.
