Description

Technical Field

[0001] This utility model belongs to the field of infant and child product technology, and specifically refers to a sippy cup for learning to suck. Background Technology

[0002] A sippy cup is a training cup specifically designed for infants transitioning from bottles to independent drinking. Its key feature is that when a baby sucks on the cup by covering the rim with their lips, a leak-proof valve opens, allowing drinking water to flow out. If not subjected to external pressure, the valve's upper edge remains sealed against the rim, preventing water from leaking out. Utility model patent number 201420212542.0 illustrates a typical sippy cup structure. However, existing sippy cups generally suffer from a problem: the leak-proof valve is made of a soft, elastic material, while the rim is typically made of hard plastic. When a child drinks, their upper lip and upper teeth touch the valve, while their lower lip and lower teeth touch the hard outer wall of the rim. During sucking, this can cause discomfort as the lower teeth may bump against each other. Summary of the Invention

[0003] The purpose of this invention is to provide a sippy cup for children to improve their drinking experience.

[0004] The purpose of this utility model is achieved as follows:

[0005] A sippy cup includes a cup body and a cup neck. The upper part of the cup neck is provided with an annular sippy opening, and the lower part of the cup neck is provided with a screw-on part and fixed to the opening of the cup body. An elastic leak-proof valve cap is covered inside the annular sippy opening, and a soft protective sleeve is fitted outside the annular sippy opening. The upper end of the leak-proof valve cap extends to the inner side of the top of the annular sippy opening, and the upper end of the protective sleeve extends to the outer side of the top of the annular sippy opening.

[0006] Furthermore, a bayonet is provided inside the cup neck, the lower end of the anti-leak valve cover is fitted into the bayonet, and a liquid outlet hole is provided around the bayonet. There is a gap between the inner wall of the annular sucking mouth and the anti-leak valve cover to form a liquid outlet channel, and the liquid outlet channel is connected to the inner cavity of the cup body through the liquid outlet hole.

[0007] Furthermore, the bottom of the leak-proof valve cover is provided with a V-shaped valve for one-way air intake, with the tip of the V-shaped valve facing the inner cavity of the cup.

[0008] Furthermore, the cup neck is formed by assembling the annular sucking mouth and the screw-in portion.

[0009] Furthermore, the inner wall of the screw-in part is provided with an upper internal thread and a lower internal thread. The upper internal thread is used to connect and fix the annular sucking mouth, and the lower internal thread is used to connect and fix the cup body.

[0010] Furthermore, the outer wall of the annular sucking opening is provided with a flange, the lower end of the sheath is supported on the upper side of the flange, and the lower side of the flange is supported on the end face of the screw-in part; the annular sucking opening is provided with a threaded interface below the flange, which engages with the upper internal thread of the screw-in part.

[0011] Furthermore, the leak-proof valve cover is made of silicone, and the protective sleeve is made of silicone.

[0012] Furthermore, the outer wall of the screw-on part is integrally formed with a handle.

[0013] Furthermore, a dust cover is fitted onto the neck of the cup, which covers the flange and supports it on the upper surface of the screw-on portion.

[0014] The outstanding and beneficial technical effects of this utility model compared with the prior art are: the utility model provides a soft protective sleeve on the outside of the sucking area, which better protects the child's lower lip and lower teeth, and improves the user experience of the sucking sippy cup.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-4 :

[0021] A sippy cup for learning to drink includes a cup body 1 and a cup neck 2. The upper part of the cup neck 2 has an annular sippy spout 2b, and the lower part of the cup neck 2 has a screw-on portion 2a fixed to the opening of the cup body 1. Preferably, the annular sippy spout 2b and the screw-on portion 2a are assembled separately for easy cleaning. The specific assembly method is as follows: Figure 3 and Figure 4As shown, an upper internal thread 2a1 and a lower internal thread 2a2 are respectively provided on the inner side wall of the screw-in part 2a. The lower internal thread 2a2 is used to connect and fix with the cup body 1, while the upper internal thread 2a1 is engaged with the threaded interface at the bottom of the annular sucking mouth 2b.

[0022] Combination Figure 2 and Figure 3 A flexible leak-proof valve cap 4 is fitted inside the annular sippy opening 2b, and a soft protective sleeve 5 is fitted outside the annular sippy opening 2b. The upper end of the leak-proof valve cap 4 extends to the inner top of the annular sippy opening 2b, and the upper end of the protective sleeve 5 extends to the outer top of the annular sippy opening 2b. This design ensures that both the child's teeth and lips are in contact with the soft material when drinking, enhancing the drinking experience.

[0023] The leak-proof valve cover 4 here adopts a shape similar to an inverted bronze bell. A latch 2b3 is set inside the neck 2, and a groove 4b is set on the lower outer wall of the leak-proof valve cover 4. The groove 4b is embedded in the latch 2b3 to fix the leak-proof valve cover 4. Figure 3 The bayonet 2b3 and slot 4b are in an unpaired state (to better demonstrate their structure). A liquid outlet 2b2 is provided around the bayonet 2b3. A gap exists between the inner wall of the annular spout 2b and the leak-proof valve cover 4, forming a liquid outlet channel (this gap is supported by ribs distributed on the inner wall of the annular spout 2b). The liquid outlet channel communicates with the inner cavity of the cup body 1 through the liquid outlet 2b2. A V-shaped valve 4a for one-way air intake is provided at the bottom of the leak-proof valve cover 4, with the tip of the V-shaped valve 4a facing the inner cavity of the cup body 1. The function of the V-shaped valve 4a is to ensure pressure balance inside and outside the cup body 1.

[0024] See details Figure 3 The annular sucking opening 2b has a flange 2b1 on its outer wall. The lower end of the sheath 5 is supported on the upper side of the flange 2b1, and the lower side of the flange 2b1 is supported on the end face of the screw-in part 2a. The flange 2b1 ensures the reliability of the assembly between the screw-in part 2a and the annular sucking opening 2b, and allows the sheath 5 to be reliably assembled on the outside of the annular sucking opening 2b.

[0025] Among them, the anti-leakage valve cover 4 is made of silicone, and the protective sleeve 5 is made of silicone. Silicone material is environmentally friendly and safe.

[0026] The outer wall of the screw-in part 2a is integrally formed with a handle 2c.

[0027] Combination Figure 1 and Figure 2 The cup neck 2 is covered with a dust cover 3, which covers the flange 2b1 and supports it on the upper surface of the screw-on part 2a.

[0028] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
