duck-billed drinking cup

Abstract

A duckbill sippy cup includes a cup body, a locking ring, a duckbill, and a lid. The locking ring is threaded onto the rim of the cup body, pressing the lower end of the duckbill against the rim, while the upper end of the duckbill protrudes upwards through the locking ring. One side of the locking ring has a mounting opening for rotating the lid, and the other side has a button opening for opening the lid. The upper surface of the locking ring has an upper annular stepped surface surrounding the duckbill, and the lid fits onto this surface. The outer wall of the locking ring is higher than the upper annular stepped surface to confine the lid within it. The button opening is radially protruding, and the upper annular stepped surface extends to the top surface of the button opening, with a vertical through hole on the top surface leading to the inner cavity of the button opening. The other side of the upper annular stepped surface extends to the mounting opening. This duckbill sippy cup, through the stepped design of the locking ring, effectively conceals gaps and provides better protection for the product.

Description

Technical Field

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

[0002] Sippy cups are commonly used by infants and toddlers to try drinking water independently. Their unique feature is the flattened spout, resembling a duck's bill, designed to fit the characteristics of a child's mouth and facilitate drinking. As shown in application number 202420311442.7, existing sippy cups typically consist of a lid, a duckbill, a locking ring, and a cup body. The lid fits over the duckbill to protect it from contamination. However, the lid and locking ring are usually exposed, resulting in poor aesthetics. Furthermore, during outdoor use, dust and impurities can easily seep in through this gap, or external impacts can cause excessive stress on the lid's hinge, leading to damage. Summary of the Invention

[0003] The purpose of this invention is to provide a duckbill sippy cup that, through the stepped design of the locking ring, conceals gaps and provides better protection for the product.

[0004] The purpose of this utility model is achieved as follows: A duckbill sippy cup includes a cup body, a locking ring, a duckbill, and a cup lid. The locking ring is threadedly connected to the rim of the cup body and presses the lower end of the duckbill against the rim. The upper end of the duckbill protrudes upward from the locking ring. One side of the locking ring is provided with a mounting port for rotating the cup lid, and the other side of the locking ring is provided with a button port for opening the cup lid. The upper end face of the locking ring is provided with an upper annular stepped surface surrounding the duckbill. The cup lid is placed on the upper annular stepped surface. The outer side wall of the locking ring is higher than the upper annular stepped surface to limit the cup lid within it. The button port is radially protruding. The upper annular stepped surface extends to the top surface of the button port and has a vertical through hole on the top surface leading to the inner cavity of the button port. The other side of the upper annular stepped surface extends to the mounting port.

[0005] Furthermore, the lower part of the inner wall of the locking ring is an internal threaded opening for connecting the cup body, and the upper part of the inner wall closes to form an inverted trumpet-shaped opening, and an arc-shaped positioning inner convex surface is formed at the mounting opening; the duckbill is fitted and installed at the inverted trumpet-shaped opening, and an arc-shaped positioning inner concave surface is formed corresponding to the arc-shaped positioning inner convex surface.

[0006] Furthermore, a lower annular step surface is formed between the inverted trumpet-shaped opening and the internal threaded opening, and a convex lip is provided at the lower end of the duckbill, the convex lip being pressed against the cup mouth by the lower annular step surface.

[0007] Furthermore, the lower annular step surface is provided with a groove, and waist-shaped positioning recesses are evenly distributed at the bottom of the groove.

[0008] Furthermore, a pair of handles are integrally provided on the outside of the locking ring.

[0009] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0010] The duckbill sippy cup of this utility model has an annular stepped surface at the locking ring, which, together with the higher outer wall, cleverly hides the gap at the lid's fitting surface. It is not only aesthetically pleasing but also serves to limit and protect the lid. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1 —8:

[0021] A duckbill sippy cup, combined with Figure 1 and Figure 2The cup includes a cup body 1, a locking ring 2, a duckbill 4, and a cup lid 3. The upper opening of the cup body 1 is provided with an external thread, and the lower opening of the locking ring 2 is provided with an internal thread 2g. The two are connected by threads. The duckbill 4 is fitted inside the locking ring 2, and the lower end of the duckbill 4 is pressed and fixed to the end face of the cup mouth by the locking ring 2. The upper end of the duckbill 4 protrudes upward from the locking ring 2.

[0022] Combination Figure 2 and Figure 4 A mounting port 2b for rotating the cup lid 3 is provided on one side of the locking ring 2. A rotating shaft and a torsion spring are mounted on the mounting port 2b to apply force to open the cup lid 3, achieving a spring-loaded effect. A button port 2a for opening the cup lid 3 is provided on the opposite side of the locking ring 2. The button port 2a, with a button and a spring, enables the cup lid 3 to be opened and unlocked.

[0023] Combination Figure 4 and Figure 5 The upper end face of the locking ring 2 is provided with an upper annular stepped surface 2d surrounding the duckbill 4. The button opening 2a is radially convex. The upper annular stepped surface 2d extends to the top surface of the button opening 2a, and a vertical through hole is opened on the top surface to lead to the inner cavity of the button opening 2a, so as to facilitate the insertion of the latch of the cup lid 3 into the inner cavity. The other side of the upper annular stepped surface 2d extends to the mounting opening 2b to achieve full coverage of the closing gap of the cup lid 3.

[0024] See details Figure 3 In the enlarged view, when the cup lid 3 is closed on the upper annular step surface 2d, the outer wall of the locking ring 2 is higher than the upper annular step surface 2d to limit the cup lid 3 within it, thus providing effective protection.

[0025] Combination Figure 3 and Figure 6 The upper part of the inner wall of the locking ring 2 closes to form an inverted trumpet-shaped opening 2f, and an arc-shaped positioning inner convex surface 2e is formed at the mounting opening 2b; the duckbill 4 is fitted into the inverted trumpet-shaped opening 2f, and an arc-shaped positioning inner concave surface 4b is formed corresponding to the arc-shaped positioning inner convex surface 2e (as shown in the attached figure). Figure 8 (As shown). The above-described structure enables a more reliable engagement and positioning of the locking ring 2 and the duckbill 4.

[0026] Combination Figure 3 and Figure 7 A lower annular stepped surface 2h is formed between the inverted trumpet-shaped opening 2f and the internal threaded opening 2g. A convex lip 4a is provided at the lower end of the duckbill 4, and the convex lip 4a is pressed tightly against the cup mouth by the lower annular stepped surface 2h. The lower annular stepped surface 2h is provided with a ring of grooves 2i, and waist-shaped positioning recesses 2j are evenly distributed at the bottom of the grooves 2i. This structure ensures that the duckbill 4 is reliably locked onto the cup body, guaranteeing a seal and preventing leakage.

[0027] See details Figure 6The locking ring 2 has a pair of handles 2c integrated on its exterior. The integrated handles 2c design reduces the number of parts, and the locking ring 2 can be easily screwed onto the opening of the cup body 1 with the help of the handles 2c.

[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.
