Description
Technical Field
[0001] The utility model relates to the technical field of daily necessities, and more specifically to a cup protective cover with one-way air return and a milk bottle with one-way air return. Background Art
[0002] Whether at home or out, containers for liquids often appear in people's daily lives, such as water cups. Compared with open water cups, bottles have good sealing properties, which can prevent accidental spillage of liquids and are more popular with people. However, bottles can also have unsatisfactory properties when used. First, thermal expansion and contraction will cause negative pressure in the bottle, making it difficult to open the lid; second, when used with a straw, pacifier, etc., as the liquid in the bottle decreases, negative pressure will also appear in the bottle, making it inconvenient to drink. Especially in the second case, the disadvantages are more obvious when the bottle is used with a pacifier (as a baby bottle).
[0003] When used as a baby bottle, in order to balance the negative pressure, a return valve is often set at the nipple to allow air to enter the bottle when there is negative pressure. Although this can solve the negative pressure problem, it will also introduce new problems. When used by young children, they are prone to inhaling bubbles and causing bloating, and when the bubbles pass through the milk, they will also oxidize the milk, causing nutrient loss.
[0004] There are some technical solutions in the prior art that can solve the problems of negative pressure, flatulence, and milk oxidation. For example, in the patent application document with application number 202210820869.5 and the name of the invention, an air return container is disclosed. In the air return container, the air return valve has an interference fit with the mounting hole, and can return air to the air return container to compensate for the negative pressure in the air return container, making it convenient for the user to ingest the liquid in the air return container. The air return valve is installed at the mounting hole, and can play a one-way conduction role, which can not only compensate for the negative pressure in the air return container, but also prevent the liquid in the air return container from leaking out.
[0005] In the process of warming and cooling milk, the above-mentioned air return container needs to use an external warm milk pad to block the air return valve. The function of the warm milk pad is to prevent negative pressure from being generated in the air return container during the cooling process of the milk. Other substances enter the air return container through the air return valve and pass through the milk in the air return container to the top of the air return container, which may cause nutrient loss in the milk. However, the warm milk pad needs to be taken out and placed separately each time it is used, and the external warm milk pad is easy to lose. Once lost, it cannot effectively block the air return valve, thereby affecting the normal function of the air return container. Utility Model Content
[0006] In order to overcome the problem that the air return valve of the existing air return container needs to use an external milk warming pad to block the air return valve during the process of warming and cooling milk, but the milk warming pad needs to be taken out and placed separately each time it is used, and the external milk warming pad is easy to be lost.

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0027] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present utility model are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices. Terms such as "setting" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. The directions or positions indicated by the terms "upper", "lower", "left", "right", "front", "back", "bottom", etc. are based on the directions or positions shown in the drawings, which are only for the convenience of description and cannot be understood as limitations on the present technical solution.
[0028] It should be noted that the existing air return container needs to use an external warm milk pad to seal the air return valve when heating and cooling milk (or other liquids). The function of the warm milk pad is to prevent negative pressure from being generated in the air return container during the cooling process of the milk, so that other substances can enter the air return container through the air return valve, and then pass through the milk in the air return container to reach the top of the air return container, which may not only affect the purity of the milk, but also cause the loss of nutrients in the milk, reducing the nutritional value of the milk. However, the warm milk pad needs to be taken out and placed separately each time it is used, which increases the complexity of the operation. In addition, the external warm milk pad is small in size and easy to slip and lose. Once lost, it cannot effectively block the air return valve, thereby affecting the normal function of the air return container.
[0029] like Figure 1-Figure 4 As shown, this embodiment provides a one-way air return cup protective cover 1, and a flexible movable plug 12 is arranged on the cup cover body. The flexible movable plug 12 can be freely switched between the bottom of the return valve 11 and the storage groove 13, which not only achieves the purpose of blocking the return valve 11, but also ensures the convenience of use.
[0030] Specifically, the cup protective cover 1 includes a cup cover main body, which is sleeved outside the cup body. The cup cover main body is provided with a one-way air return valve 11, a flexible movable plug 12 and a storage groove 13. One end of the flexible movable plug 12 is connected to the cup cover main body, and the other end of the flexible movable plug 12 extends outward to form a blocking portion 121. The blocking portion 121 is placed at the bottom of the air return valve 11 or in the storage groove 13, and switches between the bottom of the air return valve 11 and the storage groove 13 to prevent the air return valve 11 from returning air when the cup is not in use.
[0031] When the cup is being heated or cooled, the blocking portion 121 of the flexible movable plug 12 moves to the bottom of the air return valve 11, tightly blocking the air return valve 11, thereby preventing the air return valve 11 from returning air during the heating or cooling process. When the cup is used for drinking water, the blocking portion 121 can be moved to the storage groove 13, which will not affect the normal use of the air return valve 11 and can prevent it from being lost.
[0032] In one embodiment, the cup sleeve body is sleeved on the bottom of the cup body, and the shape of the cup sleeve body is adapted to the shape of the bottom of the cup body, whether it is round, square or other irregular shapes, it can achieve seamless docking. This design not only improves the stability of the cup sleeve body, making it less likely to slip or move, but also effectively enhances the heat preservation effect, ensuring that the temperature of the milk is maintained for a long time. In addition, the shape is highly matched, and the cup sleeve body can fit tightly on the bottom of the cup body, effectively preventing milk or other liquids from leaking out from the bottom.
[0033] In one embodiment, the bottom of the cup sleeve body is recessed inward to form an inner concave surface 14, and the return valve 11, the flexible active plug 12 and the storage groove 13 are all located on the inner concave surface 14. The setting of the inner concave surface 14 provides a storage space for the return valve 11, the flexible active plug 12 and the storage groove 13, does not affect the normal use of the cup sleeve body, and makes the overall design more compact and beautiful.
[0034] Preferably, the inner concave surface 14 rises smoothly at the periphery until it meets the bottom surface of the cup sleeve body. This not only improves the overall visual effect, but also enhances the structural stability of the cup sleeve body. The smooth transition makes the entire cup sleeve body more comfortable to the touch and avoids the discomfort that may be caused by sharp corners.
[0035] In one embodiment, the flexible active plug 12 is further provided with a stretching portion 122 , and the stretching portion 122 is connected to the blocking portion 121 so as to quickly pull out the blocking portion 121 .

[0039] In one embodiment, the inner diameter of the top of the cup protective sleeve 1 is smaller than the outer diameter of the bottle body at the corresponding position of the top of the cup protective sleeve 1. The cup protective sleeve 1 can fit tightly on the bottle body to further prevent milk or other liquids from leaking out.
[0040] In one embodiment, the air return valve 11 includes a valve lip 111 and a valve body 112 and an air path running through the valve body 112. An air gap connected to the air path is provided on the valve lip 111, so that air can flow smoothly into the air gap through the air path, thereby achieving the purpose of one-way air return.
[0041] Preferably, the valve lip portion 111 is located above the mounting hole, and the valve body portion 112 is interference fit with the mounting hole.
[0042] The cup protective cover 1 is made of silicone, which is soft and durable, thus ensuring the comfort of the cup protective cover 1 and increasing its service life.
