Technical Field

[0001] This utility model relates to the field of maternal and infant products, and more specifically, to a portable breast milk collection and storage device. Background Technology

[0002] Currently, breast milk collection and storage devices on the market generally suffer from complex structures and poor portability. Traditional electric breast pumps rely on complex pump and tubing systems, are bulky, and require an external power source, making them unsuitable for breastfeeding women using them when out and about. Manual breast pumps, while not requiring a power source, often employ a split design, with the collection component and storage bottle connected by multiple sealing assemblies. This not only makes operation cumbersome but also presents challenges such as inconvenient disassembly and cleaning, and the easy loss of parts. Furthermore, the one-way valve structure of existing devices is mostly an independent rigid component with a complex connection method to the bottle, making leakage or seal failure prone to occur. This fails to ensure functionality while simultaneously prioritizing portability and hygiene.

[0003] How to invent a portable milk collection and storage device to improve these problems has become an urgent problem for those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a portable breast milk collection and storage device, which aims to improve the problems of existing electric breast pumps, which have complex structures, poor portability, and relatively high manufacturing and usage costs, while manual breast pumps have highly separable parts, rely on multiple sealing connections, and are relatively cumbersome to operate and have low stability.

[0005] This utility model is implemented as follows: A portable breast milk collection and storage device includes a flexible negative pressure storage bottle. The flexible negative pressure storage bottle includes a bottle body, and a flexible partition is integrally formed between the inner walls of the middle part of the bottle body. A through hole is opened in the middle of the flexible partition, and a plurality of valves arranged in a ring are integrally formed on the inner wall around the through hole. The flexible partition divides the internal space of the bottle body into upper and lower parts of a negative pressure chamber and a storage chamber. A collection connection bottle mouth is provided at the top of the negative pressure chamber, and a breast milk collection part is detachably connected to the outside of the collection connection bottle mouth.

[0006] In a preferred embodiment of this utility model, the bottom end of the storage cavity is connected to a discharge port, and a sealing cap is detachably connected to the outside of the discharge port.

[0007] In a preferred embodiment of this utility model, the collecting bottle opening and the milk collecting part, as well as the discharge bottle opening and the sealing cap, are all connected by threaded connections.

[0008] In a preferred embodiment of this utility model, the bottle body is made entirely of transparent material.

[0009] In a preferred embodiment of this utility model, the outer wall of the bottle is provided with a capacity scale marking.

[0010] In a preferred embodiment of this utility model, the milk collection part includes a connecting tube, the connecting tube having an overall L-shaped structure, one end of the connecting tube being connected to a collection cover, and the other end of the connecting tube being provided with a connecting port, the inner wall of the connecting port being provided with a threaded groove corresponding to the thread on the outer wall of the collection connecting bottle opening.

[0011] In a preferred embodiment of this utility model, a sealing port is integrally provided on one side of the outer wall of the connecting pipe, and a threaded groove corresponding to the thread on the outer wall of the collecting connecting bottle is also provided on the inner wall of the sealing port.

[0012] The beneficial effects of this utility model are as follows: This utility model provides a portable breast milk collection and storage device through the above design.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a portable breast milk collection and storage device, including a flexible negative pressure storage bottle 1. The flexible negative pressure storage bottle 1 includes a bottle body 101. A flexible partition 102 is integrally provided between the inner walls of the middle part of the bottle body 101. A through hole is opened in the middle of the flexible partition 102. A plurality of valves 103 arranged in a ring are integrally formed on the inner wall around the through hole. The flexible partition 102 divides the internal space of the bottle body 101 into two parts: a negative pressure chamber 104 and a storage chamber 105. A collection connection bottle mouth 106 is provided at the top of the negative pressure chamber 104. A breast milk collection part 2 is detachably connected to the outside of the collection connection bottle mouth 106.

[0021] It should be noted that the bottle body 101 is made entirely of food-grade flexible silicone, possessing excellent elasticity and flexibility, capable of withstanding repeated compression without deformation, and meeting the safety standards for baby products. In its initial state, the bottle body 101 is naturally extended, with a cylindrical shape for easy gripping and squeezing. The flexible partition 102 is also made of food-grade flexible silicone and is integrally molded with the bottle body 101. It divides the internal space of the bottle body 101 into a negative pressure chamber 104 and a storage chamber 105. A through-hole is provided in the center of the flexible partition 102. The valves 103 are made of the same material as the bottle body 101 and the flexible partition 102, and are fan-shaped. Several valves 103 are integrally formed on the inner wall around the through-hole, arranged in a ring. The root of each valve 103 is connected to the inner wall of the through-hole, while the tip is freely suspended. In its initial state, the valves 103 are slightly tilted towards the storage chamber 105, forming an angle of 15°-30° with the plane of the flexible partition 102. The valves are available in 3 or 4 pieces. With 3 pieces, the odd number helps prevent symmetrical valve jamming; with 4 pieces, the uniformity of the seal is enhanced. The valve 103 can move flexibly in different operating procedures, enabling unidirectional milk flow. Simultaneously, the one-piece design reduces gaps between components, lowers the risk of leakage, and facilitates cleaning and sterilization.

[0022] Please see Figure 2 and Figure 3 The bottom end of the storage cavity 105 is connected to a discharge port 107, and a sealing cap 108 is detachably connected to the outside of the discharge port 107.

[0023] The design of the discharge spout 107 allows users to directly transfer breast milk from the storage chamber 105 to other containers, such as baby bottles, for convenient infant feeding. The sealing cap 108 effectively prevents external bacteria, dust, and other contaminants from entering the storage chamber 105, extending the storage time of the breast milk and ensuring its quality. This improves the practicality of the device and the user experience.

[0024] Furthermore, the collection connection bottle opening 106 and the milk collection part 2, as well as the discharge bottle opening 107 and the sealing cap 108, are all connected by threaded connections.

[0025] The outer side of the collecting connection bottle opening 106 is machined with external threads. The inner wall of the connecting port 203 of the milk collection part 2 is machined with internal threads that match the threads on the outer wall of the collecting connection bottle opening 106. During installation, align the connecting port 203 with the collecting connection bottle opening 106, and then rotate the milk collection part 2 to engage the threads until a tight connection is achieved. The discharge bottle opening 107 is connected to the sealing cap 108 using the same threaded connection. The threaded connection structure uses the friction between the threads to ensure a tight connection between the components, preventing loosening during use and avoiding milk leakage. It also prevents external air and contaminants from entering the device, ensuring the quality and hygiene of the milk. Users can easily disassemble and install the device without the need for other tools, facilitating cleaning and maintenance and improving the ease of use of the product.

[0026] Furthermore, the bottle body 101 is made entirely of transparent material.

[0027] Bottle 101 is made of transparent, food-grade flexible silicone. During production, the silicone's transparency is ensured to be uniform and consistent, free from bubbles, impurities, or other defects that could affect observation. The transparency of Bottle 101 should allow users to clearly see the milk inside. Direct observation of the milk's condition eliminates the need to open the container for inspection, avoiding unnecessary contamination and the risk of leakage. This provides users with greater peace of mind and enhances the product's user experience.

[0028] Furthermore, the outer wall of the bottle 101 is marked with capacity markings.

[0029] The capacity markings can be laser-engraved, printed, or affixed to the outer wall of the bottle 101. The markings are clear, accurate, and labeled with corresponding numbers. The range of the markings is set according to the capacity of the bottle 101, for example, from 0 to 300ml, to meet the needs of different users. The capacity markings allow users to accurately know the amount of milk stored in the bottle, avoiding over-collection or insufficient milk due to inaccurate judgment. This increases the practicality and functionality of the product, making the device more suitable for users' actual needs.

[0030] Please see Figure 2 and Figure 4 The milk collection section 2 includes a connecting pipe 201, which is L-shaped in shape. One end of the connecting pipe 201 is connected to a collection cover 202, and the other end of the connecting pipe 201 is provided with a connecting port 203. The inner wall of the connecting port 203 is provided with a threaded groove corresponding to the thread on the outer wall of the collection connecting bottle mouth 106.

[0031] The connecting tube 201 has an overall L-shaped structure and is made of food-grade plastic, possessing a certain degree of hardness and toughness. The L-shaped design allows users to adjust the angle of the collection cover 202 according to their posture and needs, making it more convenient to fit the breast. The collection cover 202 is made of soft silicone, and its shape and size are designed according to ergonomic principles. The opening shape of the collection cover 202 can closely fit the breast, and the edges have a certain degree of elasticity, allowing it to deform appropriately according to the shape of the breast, reducing air entry and improving the efficiency of milk collection. The inside of the collection cover 202 can be equipped with massage protrusions to massage the breast during milk collection, promoting milk secretion. The connecting port 203 is connected to one end of the connecting tube 201, and its inner wall has a connection structure that mates with the outer wall of the collection connection bottle opening 106. Through this connection structure, milk can flow from the collection cover 202 through the connecting tube 201 into the negative pressure chamber 104.

[0032] Furthermore, a sealing port 204 is integrally provided on the outer wall of one side of the connecting pipe 201, and a threaded groove corresponding to the thread on the outer wall of the collecting connecting bottle mouth 106 is also provided on the inner wall of the sealing port 204.

[0033] The sealing port 204 is integrally formed on the outer wall of one side of the connecting tube 201, and its structure is the same as that of the connecting port 203. Its inner circumference also has a connection structure adapted to the outer wall of the collecting connection bottle opening 106. When the milk collection section 2 is not in use, the sealing port 204 is aligned with the collecting connection bottle opening 106, and rotated to ensure a tight connection. The sealing port 204 increases the device's sealing performance, further preventing milk leakage and external contamination, thus ensuring the quality and hygiene of the milk. When carrying or storing the device, the milk collection section 2 can be connected to the flexible negative pressure storage bottle 1 via the sealing port 204, preventing the loss or damage of components and reducing the space occupied. This makes the portable milk collection and storage device more functional, improving product integrity and user experience.

[0034] Working principle: During use, the user squeezes the body 101 of the flexible negative pressure storage bottle 1. The body 101 deforms due to the flexible silicone material, and internal air is expelled through the milk collection section 2. After being released, the body 101 elastically returns to its original position, creating negative pressure within the negative pressure chamber 104. At this time, the external atmospheric pressure is greater than the pressure inside the negative pressure chamber 104. Several fan-shaped valves 103 are closed under the pressure difference and their own elasticity, preventing milk from flowing back into the storage chamber 105. Simultaneously, milk enters the negative pressure chamber 104 through the collection cover 202 of the milk collection section 2. When the body 101 is squeezed again, the pressure in the negative pressure chamber 104 increases, pushing the tips of the valves 103 towards the storage chamber 105, allowing milk to flow from the negative pressure chamber 104 into the storage chamber 105 for storage through the through-hole in the center of the flexible partition 102. After storage, the milk can be sealed and stored and accessed by the cooperation of the bottle opening 107 and the sealing cap 108. The whole process is driven by the deformation of the bottle body 101, the spatial separation of the flexible partition 102 and the unidirectional conduction of the valve 103, so as to achieve efficient and convenient milk collection and storage.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
