Description

Technical Field

[0001] The present invention relates to the technical field of baby products, and in particular to a pacifier adapter and a wearable breast pump. Background Art

[0002] A feeding bottle, which primarily consists of a bottle body and a nipple mounted on the body, is used for feeding infants. To meet the diverse needs of infants, the types of feeding bottles currently on the market are becoming increasingly diverse, and each type of feeding bottle typically requires a matching nipple. At different stages of an infant's development, different nipples need to be frequently replaced. Furthermore, with the emergence of new products and the need for new usage, people prefer wide-mouth or extra-wide-mouth nipples to those already purchased. In this case, discarding all standard feeding bottles and purchasing new ones with wide-mouth or extra-wide-mouth nipples would result in significant waste.

[0003] Currently, known feeding bottles and nipples are typically connected by threads. Accordingly, an adapter is designed to connect the feeding bottle and nipple. The adapter is provided with external threads that mate with the internal threads on the nipple cap and internal threads that mate with the external threads on the bottle neck. The adapter is then connected to the nipple to be matched, thereby enabling a nipple that originally did not match the feeding bottle to be mounted on the feeding bottle, allowing it to be connected and used, thus avoiding waste. However, this requires a separate adapter of corresponding size for each nipple type. For users who need to switch between multiple nipples, they need to replace the adapter each time they change nipples. This is not only inconvenient to use, but also easily lost.

[0040] It should also be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "inner," "outer," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0041] Please refer to the attached Figure 1An embodiment of the present invention provides a pacifier adapter, including a basic adapter 100 and an extended adapter 200 connected to the basic adapter 100; the basic adapter 100 is installed on the bottle mouth of a feeding bottle, and the basic adapter 100 and the extended adapter 200 are respectively provided with a first connecting structure 110 and a second connecting structure 210 that cooperate with the pacifier screw cap to connect with each other. Specifically, the first connecting structure 110 and the second connecting structure 210 can respectively cooperate with pacifier screw caps of different calibers to connect with each other.

[0042] The height of the basic adapter 100 is greater than that of the expansion adapter 200. For example, the ratio of the height of the basic adapter 100 to the height of the expansion adapter 200 is greater than 2:1. Furthermore, the basic adapter 100 includes a receiving section 120 and a connecting section 130. The first connecting structure 110 is disposed on the connecting section 130. When the first connecting structure 110 is used to connect to the pacifier cap, the receiving section 120 can accommodate the expansion adapter 200, preventing it from being lost when not in use.

[0043] Please refer to the attached Figure 2 The nipple adapter includes a first assembly state in which the extension adapter 200 is assembled with the receiving section 120 on the basic adapter 100. In the first assembly state, the nipple adapter is connected to the first caliber nipple screw cap through the first connecting structure 110 on the basic adapter 100. Figure 3 The nipple adapter also includes a second combination state in which the extended adapter 200 is assembled to the connecting section 130 on the basic adapter 100. In the second combination state, the nipple adapter is connected to the nipple screw cap of the second caliber through the second connecting structure 210 on the extended adapter 200. The above-mentioned nipple adapter structure can realize the assembly of two nipple screw caps with different calibers. The diameters of the first connecting structure and the second connecting structure on the nipple adapter can correspond to the size designs of wide-caliber nipples and extra-wide-mouth nipples commonly used on the market. In this way, the feeding bottle can be adapted to the standard nipple without adding the nipple adapter, and then by adding the nipple adapter and assembling the nipple adapter, it can be adapted to the wide-caliber nipple in the first combination state, and to the extra-wide-mouth nipple in the second combination state, so as to basically cover the usage needs of several major common sizes of nipples on the market, and its scope of application is wider.

[0044] Please refer to the attached Figure 4-5The base adapter 100 is generally hollow and cylindrical in shape. The connecting section 130 is located in the upper half of the base adapter 100, and the receiving section 120 is located in the lower half. The receiving section 120 is taller than the extension adapter 200, allowing the first connecting structure 110 on the connecting section 130 to be fully exposed when the extension adapter 200 is accommodated in the receiving section 120, allowing for a secure connection with the nipple cap. The extension adapter 200 is generally hollow and cylindrical in shape. When designing the size of the base adapter 100 and the extension adapter 200, not only the size of the nipple cap must be considered, but also the inner sidewall of the extension adapter 200 must fit snugly over the outer sidewall of the base adapter 100. Furthermore, a retaining structure is provided on the connecting section 130, and a positioning portion is provided on the extension adapter 200 that matches the retaining structure. The cooperation between the retaining structure and the positioning portion allows the extension adapter 200 to be assembled with the base adapter 100.

[0045] Furthermore, the connecting section 130 and the receiving section 120 are arranged at the upper and lower ends of the basic adapter 100, the limiting structure includes a limiting slide groove provided on the outer surface of the basic adapter 100, and the positioning part includes a limiting block provided on the inner surface of the extended adapter 200. For the convenience of production and processing, the limiting block and the extended adapter 200 can be processed as an integral molding, that is, the limiting block can be formed by extending inward from the inner surface of the extended adapter 200.

[0046] Optionally, the limiting slide includes a plurality of limit slides arranged at intervals along the circumferential direction of the basic adapter 100, each limiting slide includes a vertical portion extending along the axial direction of the basic adapter 100, and a horizontal portion 330 connected to the vertical portion and extending along the circumferential direction of the basic adapter 100, and the horizontal portion 330 is located at the upper end of the vertical portion; the limiting block includes a plurality of limit slides corresponding one to one; in the first combination state, the extended adapter 200 slides along the vertical portion of the corresponding limit slide through the limiting block to abut against the bottom end of the vertical portion to be received and accommodated, so that the first connection structure 110 of the basic adapter 100 can adapt to the nipple screw cap of the first caliber. At the same time, the extension adapter 200 is accommodated in the accommodating section 120 of the basic adapter 100, and the limit block abuts against the bottom end of the vertical portion, which can effectively prevent the extension adapter 200 from circumferentially moving relative to the basic adapter 100, thereby preventing the baby from rotating the extension adapter 200 while feeding, thereby affecting the baby's concentration while feeding. In addition, when the baby is feeding, by holding the outer wall of the extension adapter 200, the baby's grip on the bottle can be improved to prevent the bottle from falling; in the second combined state, the extension adapter 200 slides along the vertical portion of the corresponding limit slide groove through the limit block and abuts against and is accommodated in the horizontal portion 330, so that the second connection structure 210 of the extension adapter 200 can adapt to the second caliber nipple screw cap.

[0047] Alternatively, the first connection structure 110 may be an external thread disposed on the outer surface of the connection section 130. The external thread is formed as a plurality of discontinuous threads spaced apart along the circumference of the base adapter 100, with the limiting grooves correspondingly disposed within the spaced apart threads. Furthermore, the second connection structure 210 may be a continuous external thread disposed on the outer circumference of the expansion adapter 200.

[0048] Please refer again to the attached Figure 4 A sliding section 340 is provided at the location where the vertical portion connects to the top of the base adapter 100. An inclined guide surface is provided within the sliding section 340 to facilitate sliding the limit block into the vertical portion of the limit chute, thereby assembling the extension adapter 200 on the base adapter 100. Optionally, a spring clip 350 is provided on the inner wall of the horizontal portion 330 to secure the limit block within the horizontal portion 330. When the extension adapter 200 is assembled from the connecting section 130 of the basic adapter 100, a vertical upward force is first applied to make the limit block slide upward along the vertical portion of the limit sliding groove. When the limit block and the horizontal portion 330 are at the same horizontal plane, a clockwise external force is applied to rotate the extension adapter 200 so that the limit block squeezes the spring piece 350 and then slides into the horizontal portion 330, and the spring piece 350 rebounds and abuts against the side wall of the limit block, so that the limit block is fixedly accommodated in the horizontal portion 330. When the extension adapter 200 is assembled from the connecting section 130 of the basic adapter 100 to the receiving section 120, a counterclockwise external force is first applied to rotate the extension adapter 200 so that the limit block squeezes the spring piece 350 and then slides into the vertical portion. Then, a vertical downward external force is applied to make the limit block slide downward along the vertical portion of the limit sliding groove until it abuts and is accommodated in the bottom end of the vertical portion.

[0049] Optionally, the bottom edge of the basic adapter 100 extends outward to form a chassis 360, and the diameter of the chassis 360 is larger than the diameter of the extension adapter 200. On the one hand, when the extension adapter 200 is accommodated in the accommodating section 120 of the basic adapter 100, the chassis 360 can support the extension adapter 200. On the other hand, the user can take the entire pacifier adapter through the chassis 360, which is more convenient to operate.

[0050] The nipple adapter in the present invention, its size and specifications can be reasonably designed according to the size and specifications of existing nipples and bottles on the market. For example, the size and specifications of the basic adapter 100 and the extended adapter 200 can be reasonably designed according to the specifications of existing nipples on the market. Specifically, the size of the basic adapter 100 can be adapted to the standard nipples, wide-mouth nipples and extra-wide-mouth nipples available on the market, and the size of the extended adapter 200 can be adapted to the wide-mouth nipples and extra-wide-mouth nipples available on the market. Furthermore, the nipple adapter can be designed to include two combination states in which the extended adapter 200 is assembled on the basic adapter 100 to respectively adapt to standard nipples and wide-mouth nipples, or it can be designed to include two combination states in which the extended adapter 200 is assembled on the basic adapter 100 to respectively adapt to standard nipples and extra-wide-mouth nipples, or it can be designed to include two combination states in which the extended adapter 200 is assembled on the basic adapter 100 to respectively adapt to wide-mouth nipples and extra-wide-mouth nipples.

[0051] Optionally, the nipple adapter of the present invention is suitable for wearable breast pumps. Figure 6-7 An embodiment of the present invention provides a wearable breast pump, comprising a breast pump bottle 410 and a nipple adapter according to any one of the above embodiments. The outer side of the bottle mouth of the breast pump bottle 410 is provided with an external thread, and the inner surface of the basic adapter 100 is provided with an internal thread that is threadedly connected to the bottle mouth of the breast pump bottle 410. Through the nipple adapter, the breast pump bottle 410 can be directly used by the baby, avoiding the situation where the breast pump bottle 410 is not compatible with the nipple screw cap on the market, and breast milk needs to be poured into the bottle on the market during use of the product. In this process, bacteria in the air are easily mixed into the breast milk, or the breast milk is exposed, and other uncertainties.

[0052] In one embodiment, the wearable breast pump further includes a standard nipple 421. In a first assembled state, the nipple adapter connects to the screw cap of the standard nipple 421 via the first connecting structure 110 on the base adapter 100. If the breast pump bottle 410 does not match the standard nipple, the nipple adapter can be assembled onto the breast pump bottle 410. After the extended adapter 200 on the nipple adapter and the base adapter 100 are in the first assembled state, the screw cap of the standard nipple 421 can be assembled onto the connecting section 130 of the base adapter 100, thereby completing the connection between the breast pump bottle 410 and the standard nipple 421.

[0053] Please refer to the attached Figure 8-9In another embodiment, the wearable breast pump further includes a wide-mouth nipple 422. In the second assembly state, the nipple adapter is connected to the nipple screw cap of the wide-mouth nipple 422 through the second connecting structure 210 on the extension adapter 200. The diameter of the nipple screw cap of the wide-mouth nipple 422 is larger than the diameter of the nipple screw cap of the standard nipple 421. In the event that the breast pump bottle 410 and the wide-mouth nipple 422 do not match, the nipple adapter is assembled on the breast pump bottle 410, and after the extension adapter 200 and the basic adapter 100 on the nipple adapter are in the second assembly state, the screw cap of the wide-mouth nipple 422 can be assembled on the outer wall of the extension adapter 200, thereby realizing the connection between the breast pump bottle 410 and the wide-mouth nipple 422.

[0054] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this invention should be included in the scope of protection of the present invention. The scope of protection of the present invention should be based on the scope of protection of the claims.
