Description

Technical Field

[0001] The present invention relates to the technical field of containers, and particularly to a heat-insulating baby bottle. Background Art

[0002] As a common daily necessity, heat-insulating baby bottles are widely used in various scenarios to keep the temperature of beverages. Currently, most heat-insulating baby bottles on the market lack an effective temperature reminder device. When users drink, they cannot directly understand the temperature of the liquid in the cup. Especially when the temperature is relatively high, users may be scalded because they cannot accurately judge the temperature. Although some heat-insulating baby bottles are designed with an external temperature indication device, these devices are usually located outside the cup body. They can neither directly reflect the real-time temperature of the liquid in the cup nor have a great impact on the appearance of the cup body, and are likely to damage the aesthetics of the overall design. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a heat-insulating baby bottle that can accurately prompt the real-time temperature of the liquid in the cup without affecting the appearance of the cup body.

[0004] A heat-insulating baby bottle includes:

[0005] A bottle body having a bottle mouth portion;

[0006] A nipple assembly detachably connected to the bottle mouth portion. The nipple assembly includes a nipple and a straw. The nipple includes a mouth body and a connecting portion located inside the mouth body. The connecting portion is detachably connected to the straw;

[0007] Part or all of the nipple is made of a transparent or semi-transparent material. The nipple assembly further includes a temperature-sensitive color-changing member connected to the straw and close to the bottle mouth portion. The temperature-sensitive color-changing member can present corresponding color changes according to temperature changes.

[0008] In one embodiment, the temperature-sensitive color-changing member is disc-shaped, and a limiting step is provided on the inner wall of the bottle mouth portion. The edge of the temperature-sensitive color-changing member is supported on the limiting step.

[0009] In one embodiment, a cylindrical inner plug is provided inside the nipple. The inner plug is inserted into the bottle mouth portion and is in sealed cooperation with the bottle mouth portion. The lower end of the inner plug is in pressing cooperation with the edge of the temperature-sensitive color-changing member and the limiting step.

[0010] In one embodiment, the lower end of the inner plug is provided with an annular recess with an inward opening, and the outer edge of the temperature-sensitive color-changing member is snapped into the recess.

[0011] In one embodiment, a magnifying structure is provided on the mouth body between the inner plug and the connecting portion.

[0012] In one embodiment, an air return hole is provided on the temperature-sensitive color-changing member.

[0013] In one embodiment, the straw includes a straw body made of a soft material and a connector made of a hard material. The lower end of the connector is integrally formed with the upper end of the straw body. The upper end of the connector is detachably connected to the nipple, and the temperature-sensitive color-changing member is installed on the connector.

[0014] In one embodiment, the connecting portion is cylindrical, and a clamping groove or a clamping protrusion is provided on the inner wall of the connecting portion. A clamping protrusion or a clamping groove is provided on the outer wall of the connector to cooperate with the clamping groove or the clamping protrusion. The connector is inserted into the connecting portion through the lower end opening of the connecting portion, and the clamping protrusion is snapped into the clamping groove.

[0015] In one embodiment, the connecting portion extends to a position close to the temperature-sensitive color-changing member, and the lower end opening of the connecting portion is trumpet-shaped.

[0016] In one embodiment, the bottle body includes a heat-insulating container main body and a detachable bottom pad assembled at the bottom of the heat-insulating container.

[0017] For the above heat-insulating baby bottle, when the temperature of the liquid in the bottle is higher than the set temperature threshold, the temperature-sensitive color-changing member will change color and display a warning color. The user can intuitively observe this change through the transparent or semi-transparent nipple, so as to quickly judge the temperature of the liquid in the bottle. Since the temperature-sensitive color-changing member is hidden inside the baby bottle, it will not affect the aesthetic appearance of the baby bottle design. At the same time, it can provide accurate real-time temperature prompts, effectively avoiding the risk of scalding caused by the inability to judge the liquid temperature.

[0061] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the description of the present invention in this article are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0062] Embodiment 1

[0063] See Figures 1-6, the insulated feeding bottle in an embodiment of the present invention includes a bottle body 1 and a nipple assembly 2. Among them, the bottle body 1 has a bottle mouth portion 11 for connecting with the nipple assembly 2. The nipple assembly 2 is detachably connected to the bottle mouth portion 11, which is convenient for cleaning and replacement. The nipple assembly 2 mainly consists of a nipple 21, a straw, and a mouthpiece base 26. The nipple 21 includes a mouth body 211 for the baby to suck and a connecting portion 212 located inside the mouth body 211. Part or all of the nipple 21 is made of transparent or translucent material, ensuring good visibility. The connecting portion 212 is detachably connected to the straw 3, which is convenient for assembly and cleaning. The mouthpiece base 26 is a ring structure. The mouthpiece base 26 is connected to the nipple 21 and is threadedly connected to the bottle mouth portion 11. In one embodiment, the mouthpiece base 26 and the nipple 21 are of a split structure. An annular groove is provided on the outer wall of the lower end of the nipple 21, and an annular rib matching the annular groove is provided on the inner wall of the mouthpiece base 26. The annular rib is snapped into the annular groove.

[0064] The nipple assembly 2 further includes a temperature-sensitive color-changing member 23, which is connected to the straw 3 and is close to the bottle mouth portion 11. The temperature-sensitive color-changing member 23 can present corresponding color changes according to the temperature change of the liquid in the feeding bottle, visually showing the milk temperature to the user and avoiding scalding the baby. In one embodiment, the temperature-sensitive color-changing member 23 can be made of thermochromic plastic or silicone. The thermochromic pigment can be directly added to polymer materials such as plastic or silicone and made into a component with temperature-sensitive color-changing function through processes such as injection molding or compression molding. Considering the safety of baby products, plastics or silicones meeting food-grade standards should be selected, and it is ensured that the thermochromic pigments used therein are also safe and non-toxic.

[0065] In one embodiment, the temperature-sensitive color-changing member 23 is preferably in a disc shape. A limiting step 12 is provided on the inner wall of the bottle mouth portion 11. The edge of the temperature-sensitive color-changing member 23 is directly supported on the limiting step 12. Through this limiting step structure, precise positioning and fixation of the temperature-sensitive color-changing member are achieved; moreover, since the temperature-sensitive color-changing member 23 is installed on the straw 3 and the straw 3 is connected to the nipple 21, the limiting step 12 can also provide partial support for the nipple 21 to a certain extent. This allows the nipple 21 to adopt a thinner and lighter design to some extent, making it convenient to install the mouth body on the mouthpiece base 26; and it is softer and more comfortable to suck.

[0066] In one embodiment, a cylindrical inner plug 24 is provided inside the mouth body 211. The inner plug 24 is inserted into the bottle mouth portion 11 and forms a sealing fit with the bottle mouth portion 11, effectively preventing liquid leakage. The lower end of the inner plug 24 forms a pressing fit with the edge of the temperature-sensitive color-changing member 23 and the limiting step 12. The inner plug 24 not only realizes reliable sealing with the bottle mouth portion to prevent heat dissipation and increase the heat preservation effect. More importantly, the lower end of the inner plug 24 helps to fix the temperature-sensitive color-changing member 23 on the limiting step 12 by pressing the edge of the temperature-sensitive color-changing member 23.

[0067] When the heat-insulating milk bottle is in use, fog will be generated in the space above the temperature-sensitive color-changing member 23, making it impossible to clearly see the temperature-sensitive color-changing member 23 from the outside and accurately judge the temperature of the liquid. To solve this problem, the present application innovatively designs an annular recess 25 with an inward opening at the lower end of the inner plug 24, and the outer edge of the temperature-sensitive color-changing member 23 just fits into the annular recess 25. In this way, the temperature-sensitive color-changing member 23 located in the annular recess 25 is effectively isolated from the fog in the thermos bottle, so that the color of the temperature-sensitive color-changing member 23 can be clearly seen through the mouthpiece 211 and the inner plug 24, facilitating the user to accurately judge the temperature of the milk liquid. To further clearly observe the edge of the temperature-sensitive color-changing member 23, a magnifying structure is also provided in the part of the nipple mouthpiece 211 between the inner plug 24 and the connecting part 212 (for example, see Figure 5 , the inner wall of the nipple mouthpiece 211 between the inner plug 24 and the connecting part 212 protrudes inward to form a convex lens structure 220, or the effect of a convex lens is formed by the specific curvature of the transparent nipple material in this area). This magnifying structure can magnify and display the contact position between the lower end of the inner plug 24 and the edge of the temperature-sensitive color-changing member 23, enabling the user to more easily and clearly read the temperature indication even when it is inconvenient to approach for observation, significantly improving the user experience.

[0068] In the above-mentioned heat-insulating milk bottle, when the temperature of the liquid in the milk bottle is higher than the set temperature threshold, the temperature-sensitive color-changing member 23 will change color and display a warning color. The user can directly observe this change through the transparent or semi-transparent nipple 21, so as to quickly judge the temperature of the liquid in the bottle. Since the temperature-sensitive color-changing member 23 is hidden inside the milk bottle, it will not affect the aesthetic appearance of the milk bottle design, and at the same time can provide accurate real-time temperature prompts, effectively avoiding the risk of scalding caused by the inability to judge the liquid temperature.

[0069] In one embodiment, the nipple assembly further includes a straw 3, and the straw 3 is detachably connected to the nipple 21. The straw 3 includes a straw body 31 and a connecting head 32. The connecting head 32 is connected to the nipple 21 through a buckle 8 or a threaded structure, and the straw body 31 extends into the bottle body 1. The temperature-sensitive color-changing member 23 is fixed on the connecting head 32 of the straw 3. With this structure, the temperature-sensitive color-changing member 23 can be firmly fixed on the connecting head 32, ensuring that it is not easily detached or displaced during use, thus ensuring the reliability and durability of the temperature prompt. As an alternative, the temperature-sensitive color-changing member 23 can also be provided in the middle or bottom of the straw 3 to sense the change in the liquid temperature and give a prompt in the same way.

[0070] In another embodiment, the temperature-sensitive color-changing member 23 is provided with an air return hole 27 (see Figure 6) The function of the air return hole 27 is to balance the air pressure inside the feeding bottle, ensure smooth liquid flow, and prevent blockage or negative pressure in the straw 3. In an alternative solution, the number and position of the air return hole 27 can be adjusted according to the size and design requirements of the feeding bottle. The air return hole 27 can also be provided on the main body of the straw 3 to achieve a similar air pressure balance function.

[0071] In one embodiment, the straw 3 includes a straw body 31 made of a soft material and a connector 32 made of a hard material. The lower end of the connector 32 is integrally formed with the straw body 31, and the upper end is detachably connected to the nipple 21. The temperature-sensitive color-changing member 23 is fixedly installed on the connector 32. With this structure, the temperature-sensitive color-changing member 23 is more firmly combined with the hard connector 32, effectively avoiding loosening or falling off of the temperature-sensitive member during use, while maintaining the flexibility of the straw 3, improving the use experience and durability of the feeding bottle. As an alternative, the straw body 31 and the connector 32 can also use the same hard material to enhance the overall durability. The temperature-sensitive color-changing member 23 can also be provided in the middle or at the bottom of the straw body 31 to ensure the accuracy of temperature perception.

[0072] In one embodiment, the connecting portion 212 is preferably cylindrical, and its inner wall is provided with a card slot 214 or a clamping protrusion. The outer wall of the connector 32 is provided with a clamping protrusion 33 or a card slot that cooperates with the card slot 214 or the clamping protrusion. The connector 32 is inserted into the connecting portion 212 through the lower opening of the connecting portion 212, and the detachable connection is achieved by clamping the clamping protrusion 33 into the card slot 214. By using the cooperation method of the card slot and the clamping protrusion, the quick, convenient and reliable disassembly and assembly of the nipple and the straw connector are realized, facilitating the user to clean and replace. Preferably, the connecting portion 212 can extend to a position close to the temperature-sensitive color-changing member 23, and the lower opening of the connecting portion 212 is designed as a flared shape 215. In this way, when the straw needs to be assembled after cleaning, the connector of the straw can be easily aligned with the lower opening of the connecting portion 212 and smoothly inserted into the connecting portion 212 under the guidance of the connecting portion 212, facilitating installation.

[0073] In one embodiment, the nipple 21 further includes a sucking portion 216 connected to the mouth body 211. A diaphragm 217 is provided in the sucking portion 216, and a cut 218 is provided on the diaphragm 217. The cut 218 is used to control the liquid flow rate to ensure that the liquid can flow out evenly during sucking. The function of the diaphragm 217 design is to prevent the liquid from overflowing due to excessive sucking force and ensure the stability of the liquid flow rate. The shape and position of the cut 218 can be adjusted according to requirements to ensure appropriate flow control.

[0074] Further, the cross-section of the diaphragm 217 in the axial direction of the sucking part 216 is a downwardly convex arc-shaped structure, and two incisions 218 on the diaphragm 217 are arranged side by side. This arc-shaped structure can increase the elasticity of the diaphragm 217 and enhance the control effect on the liquid flow rate. The design of the two incisions 218 does not affect the anti-spray effect compared with a single incision, and the water absorption effect is better.

[0075] In one embodiment, the insulated baby bottle further includes a nipple cover 4, and the nipple cover 4 is located outside the nipple body 211 and is fastened to the nipple base 26.

[0076] In one embodiment, the bottle body 1 includes a thermal insulation container main body 13 and a detachable bottom pad 5 assembled at the bottom of the thermal insulation container. The bottom pad 5 is threadedly connected to the bottom of the thermal insulation container main body 13 to ensure the stability of the bottom pad 5, and at the same time, it can be easily disassembled for easy cleaning and maintenance. The function of the bottom pad 5 is to increase the anti-slip performance of the baby bottle, prevent the baby bottle from tipping or sliding during use, and at the same time increase the stability of the baby bottle. Its technical effect is to improve the convenience and safety of using the baby bottle. In one embodiment, a fixing plate 6 is fixed on the bottom surface of the thermal insulation container main body 13, a screw hole is provided on the fixing plate 6, a through hole opposite to the screw hole is provided on the bottom pad 5, and a screw 9 passes through the through hole and is screwed into the screw hole to firmly fix the bottom pad 5 at the bottom of the thermal insulation container main body 13.

[0077] Embodiment Two

[0078] The insulated baby bottle in this embodiment is generally the same in structure as that in Embodiment One. The difference is that the connecting part 212 in this embodiment is a convex ring 219 provided on the inner wall of the nipple body 211. The convex ring 219 is snapped into the slot 214 on the outer wall of the connecting head 32.

[0079] In addition, the bottom pad 5 in this embodiment is connected to the bottom of the bottle body 1 through a snap structure. Further, a fixing plate 6 is fixed on the bottom surface of the thermal insulation container main body 13, a snap hole is provided on the fixing plate 6, and a snap 8 cooperating with the snap hole 7 is provided on the bottom pad 5. Through the cooperation connection of the snap 8 and the snap hole, the bottom pad 5 can be firmly fixed at the bottom of the thermal insulation container main body 13 to ensure that it will not loosen or fall off during use. There is a risk that the glue will lose its viscosity and fall off when encountering high or low temperatures in the traditional glue fixing method.

[0080] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
