Description

Technical Field

[0001] This utility model belongs to the technical field of water cups for infants and young children, and specifically relates to a water cup for infants and young children with a delayed venting function. Background Technology

[0002] Traditional baby water cups mainly consist of cups with lids or open-mouthed cups, which can be used directly by pouring water into them. Another common type is the portable water cup with a sippy tube. Because the cup is relatively deep, water needs to be drawn up through the tube to drink. However, none of these types of water cups are very suitable for babies. The mouth of the open-mouthed cup or the ordinary cup with a lid is too large, making it easy for water to splash onto the baby's face. As for the portable water cup with a sippy tube, babies often drink too much because they do not yet have enough control, or the water flow from the tube may be obstructed due to air pressure imbalance, making it difficult for the baby to drink. Therefore, these types of water cups need further improvement.

[0003] Chinese patent application number 201920967069.X discloses a baby water cup, comprising a cup body and a lid. The outer surface of the lid has a spout and an air hole. Correspondingly, a tubular water channel is provided on the inner surface of the spout, and a tubular air channel is provided on the inner surface of the air hole. A sealing plate is provided to seal or open the water and air channels. The cup body consists of an inner cup body and an outer cup body. The inner cup body includes a threaded rim, a central step, and a bottom cup portion. The outer cup body has the same shape as the bottom cup portion but is slightly larger. The threaded rim is screwed onto the inner side of the lid's rim. The rim of the cup rests on the central step; its advantages are: the outer cup body covers the entire bottom cup portion, with an air gap in the middle, making it less likely to burn your hands when handling the cup; the sealing plate is manufactured in one piece, with a simple structure and fewer points of leakage; the ingenious design utilizes the material's own elasticity to reset the seal, resulting in a long lifespan; the inclusion of a ball bearing and restraint or guidance mechanism adds to the fun and solves the problem of burning hands. However, when the cup contains very little water, the unbalanced air pressure causes the water to flow from the sippy tube to be uneven, making it difficult for the baby to drink, and the baby also has difficulty drinking through the spout. Therefore, an improved water cup suitable for babies is needed. Summary of the Invention

[0004] This utility model provides an infant water cup with a delayed venting function.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] like Figure 1-11This is a schematic diagram of the structure of an infant water cup with a delayed venting function proposed in this utility model. The infant water cup with a delayed venting function includes a cup body 1 and a cup lid 3. A cup lid seat 2 is detachably connected to the cup body 1, and the cup lid 3 is hinged to the cup lid seat 2. A nipple holder 9 is detachably fitted onto the top of the cup lid seat 2. A nipple is provided on the top of the nipple holder 9, extending to the upper surface of the cup lid seat 9, and a suction tube 13 is provided at the bottom of the nipple holder, extending to the bottom of the cup body and communicating with the nipple. A fastening device for fastening the cup lid 3 is provided on the cup lid seat 9 away from the hinge. The cup lid seat 2 has a button 5 on its side wall near the snap-fit ​​groove 12. The button 5 extends to the snap-fit ​​groove 12 and has a snap-fit ​​plate 25 for snapping onto the edge of the cup lid 3. The cup lid seat 2 has a vent groove 30 inside the snap-fit ​​groove 12 that communicates with the inside of the cup lid 3. The nipple seat 9 has a vent chamber 24 on its side wall inside the cup lid seat 2. The side wall of the cup lid seat 2 has a vent hole 29 for connecting the vent groove 30 and the vent chamber 24. The end of the button 5 extends through the vent groove 30 into the vent hole 29 and has a vent plate 23 for sealing the vent hole 29.

[0031] In this embodiment, when the infant water cup is filled with hot water, the hot steam will fill the entire lid 3 along the nipple, resulting in relatively high air pressure inside the lid. The lid will automatically pop open under the pressure and the action of the torsion spring. If the pressure is not released, the lid 3 can easily hit the chin or nose during the pop-opening process if one is not careful. In winter, the lid may be sucked shut by steam, which is actually caused by the pressure difference between the inside and outside of the cup. When the air inside the cup expands and contracts due to temperature changes or when steam generates high pressure, the external air pressure will be greater than the internal pressure, making it difficult to open the lid. Both of these situations are problematic for cups with good sealing properties. Water cups often have the problem of being difficult to open. In this embodiment, when the latching plate 25 is moved away from the edge of the cup lid 3 by pressing button 5, the venting plate 23 is moved away from the venting hole, and the channel between the venting groove 30 and the venting chamber 24 is opened. This balances the air pressure inside the cup lid 3 and the venting chamber 24, preventing the cup lid from opening too quickly due to excessive air pressure inside the cup lid 3. It also avoids the problem of the cup lid being sucked in, which makes it difficult to open. This achieves a delayed venting effect, where the air pressure inside the cup lid 3 is balanced before the cup lid is opened.

[0032] In this embodiment, a snap-fit ​​groove 12 and a venting groove 30 are provided in the cup lid seat 2, and a venting chamber 24 is provided on the side wall of the nipple seat 9. The button 5 extends through the snap-fit ​​groove 12 and into the venting groove 30, where a venting plate 23 is provided. A venting hole is provided on the cup lid seat between the venting chamber and the venting groove. When the button opens the cup lid, the venting plate moves away from the venting hole, allowing the air pressure between the cup lid and the nipple seat to be released into the venting chamber along the venting groove and the venting hole. After the cup lid is opened, the button resets and re-seals the venting hole. This achieves the effect of releasing the air pressure in the cup cavity at the moment the cup lid is opened, preventing the cup lid from suddenly popping up and injuring the child's face due to excessive air pressure when the cup lid is opened.

[0033] In a preferred embodiment, button 5 includes button plate 31 and inner support 32 located on the upper part of button plate 31. Vent plate 23 is located at the middle of the end of inner support 32, and fastening plate 25 is located on the inner wall of button plate 31. In this embodiment, the structure uses inner support 32 to connect vent plate 23 to button plate 31, realizing the simultaneous function of fastening cup lid and venting, which is convenient to operate.

[0034] In a preferred embodiment, the button plate 31 is provided with guide connecting pieces 22 on both sides of the inner bracket 32, and the side wall inside the cup lid seat 2 is provided with guide grooves 21 on both sides of the vent hole 29 for the guide connecting pieces 22 to pass through. The end of the guide connecting piece 22 is provided with a barb that hangs on the inner side of the cup lid seat 2. In this embodiment, this structure facilitates the guide connecting piece 22 to install the button plate 31 on the cup lid seat 2.

[0035] In a preferred embodiment, a button mounting groove 16 for accommodating the button 5 is provided on the side wall of the cup lid seat 9. The button mounting groove 16, the snap-fit ​​groove 12 and the venting groove 30 are connected. The lid structure of this embodiment facilitates the one-time molding of the cup lid seat 9, reducing costs.

[0036] In a preferred embodiment, the button mounting groove 16 is provided with an arc-shaped abutting part and a reset spring that abut against the middle of the button plate 31. In this embodiment, when the button is pressed down to open the upper part of the button outward, thereby causing the fastening plate 25 to move away from the edge of the cup lid 3, the vent plate 23 moves away from the vent hole. After the button is released, it automatically resets under the action of the reset spring.

[0037] In a preferred embodiment, the other end of the cup lid seat 2 away from the fastening groove 12 is provided with a hinge shaft 11 and a torsion spring that are connected to the cup lid. This structure in this embodiment is convenient to operate and makes it easy to open the cup lid.

[0038] In a preferred embodiment, the water suction tube 13 is detachably connected to the nipple holder 9. The end of the water suction tube 13 is provided with a snap-fit ​​groove 14, and the bottom of the nipple holder 9 is provided with a slanted connector 28 that is sealed and snapped onto the snap-fit ​​groove 14. In this embodiment, the cover structure utilizes the slanted connector 28 to allow the water suction tube 13 to extend obliquely to the bottom of the inner cavity 27 of the water cup, so that the water at the bottom of the inner cavity 27 of the water cup can be completely sucked out, leaving no residual water and improving the water suction efficiency.

[0039] In a preferred embodiment, the nipple holder 9 and the nipple are made as a single molded body. This structure is easy to process. The nipple holder 9 is fitted into the inner cavity 20 of the cup lid holder. The top of the cup lid holder 2 is provided with an arc-shaped mounting hole 15 that fits around the upper part of the nipple holder 9, so that the nipple holder 9 and the cup lid holder 2 can be sealed and connected as a whole. The cup lid holder 2 is connected to the cup body 1 by a connecting thread 10.

[0040] In a preferred embodiment, the nipple is configured as a round nipple 6, a flat nipple 7, and a cross-shaped nipple 8, which allows for the diversification of nipples.

[0041] In a preferred embodiment, the bottom of the nipple holder 9 is provided with a mounting plate that is sealed and fastened to the inner cup lid holder 2. Positioning protrusions 17 are provided on both sides of the upper surface of the mounting plate. The inner cup lid holder 2 is provided with a nipple holder mounting groove 19 for connecting the nipple holder. Positioning grooves 20 corresponding to the positioning protrusions 17 are provided on the nipple holder mounting groove 19. In this embodiment, the lid structure seals the nipple holder 9 and the cup lid holder 2 into a whole, while the positioning protrusions 17 and positioning grooves 20 prevent the nipple holder 9 from rotating on the cup lid holder 2.

[0042] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
