Description

Technical Field

[0001] The invention belongs to the technical field of cup covers, and in particular relates to an anti-spray cup cover. Background Art

[0002] At present, there are many different styles of cups on the market. Consumers are extremely concerned about the safety of cups, especially straw-type cups. For safety, to avoid water spraying from the straw when opening, the cup cover is often provided with an anti-spray function and a degassing device. However, the degassing device on the market is sealed by a sealing column on the flip cover. When the flip cover is opened, the gas in the cup will still overflow from the straw due to the small degassing channel and slow degassing speed. In addition, the water temperature in the cup is high, and the gas in the cup may be directly sprayed from the vertical degassing channel onto the flip cover, causing the cup to be damaged. The risk of scalding the user, and the air release channels on the market are all arranged vertically. For example, in the children's straw cup with Chinese invention patent number ZL201720002028.8, the pressing protrusion 18 on the button buckle 4 of the cup is pressed against the air release hole 23, and the button buckle 4 pushes the pressing protrusion 18 to be staggered with the air release hole 23. During the long-term pressing and moving process, the plastic chips on the pressing protrusion 18 are easily scraped out, and the plastic chips can easily enter the cup body cavity directly through the air permeable hole 15, which poses a hidden danger to the safety of use. Summary of the invention

[0040] The present invention will be further described below with specific embodiments in conjunction with the accompanying drawings:

[0041] Refer to Figures 1 to 9As shown in the figure, an anti-spray cup lid includes a cup lid body, and an anti-spray hole 2 is provided on the cup lid body. The outlet end 21 of the anti-spray hole 2 is horizontally arranged on the cup lid body. In this embodiment, the included angle formed between the axis of the outlet end 21 and the upper surface of the cup lid body is a; 0° ≤ a < 90°, preferably a = 0°, that is: the use effect is the best when the axis of the outlet end 21 is parallel to the upper surface of the cup lid body. This can avoid the plastic on the outlet end 21 being scraped out after the anti-spray plug 3 moves repeatedly for a long time, increasing the safety during product use. At the same time, it also avoids the disadvantages that the vertical anti-spray hole 2 cannot have a large hole, and the safety hazard brought by the vertical pressure relief of the vertical anti-spray hole 2; an anti-spray plug 3 and a button device for controlling the opening of the anti-spray plug 3 are provided at the outlet end 21 of the anti-spray hole 2, and the outlet end 21 of the anti-spray hole 2 is sealed by the anti-spray plug 3; operating the button device, the anti-spray plug 3 leaves the outlet end 21, and the inner cavity of the cup 10 communicates with the outside. Through the horizontal arrangement of the outlet end 21 of the anti-spray hole 2, a buffering effect is achieved when the air pressure in the cup is relieved, reducing the pressure when the air pressure comes out. And when the air pressure sprays out, it is towards the inner wall direction of the cup lid body, and the outlet end 21 is blocked by the anti-spray plug 3, so the air pressure will not cause direct harm to the user. Moreover, the horizontally arranged outlet end 21 can increase the aperture of the anti-spray hole 2, facilitating the discharge of air pressure; at the same time, the horizontally arranged outlet end 21 avoids the plastic on the outlet end being scraped out after the anti-spray plug 3 moves repeatedly for a long time, and prevents the scraped plastic or external impurities from entering the inner cavity of the cup 10 through the anti-spray hole 2, increasing the safety during product use.

[0042] In this embodiment, the button device includes a button body 4 and an elastic member 6. The anti-spray plug 3 is arranged on the button body 4, and the elastic member 6 makes the anti-spray plug 3 seal with the outlet end 21. Horizontally pressing the button body 4 makes the anti-spray plug 3 move with the button body 4 and separate from the outlet end 21 of the anti-spray hole 2. Through the arrangement of the elastic member 6, the anti-spray plug 3 is always sealed with the outlet end 21 without pushing the button body 4, avoiding the water in the cup spilling out from the outlet end 21 when drinking water and shaking.

[0043] At the same time, a fixing column 5 is arranged on the button body 4, the anti-spray plug 3 is sleeved on the fixing column 5, a positioning protrusion 51 is arranged on the fixing column 5, and a positioning groove 31 adapted to the positioning protrusion 51 is arranged on the anti-spray plug 3. Through the arrangement of the positioning column, the installation of the anti-spray plug 3 is facilitated, and through the cooperation of the positioning protrusion 51 and the positioning groove 31, a positioning effect is achieved when the anti-spray plug 3 is installed and fixed on the fixing column 5, and the positioning protrusion 51 also prevents the anti-spray plug 3 from rotating on the fixing column 5, playing a radial fixing effect.

[0044] Further set as: the outer port of the outlet end 21 is a flared opening with a larger outer diameter and a smaller inner diameter, or the outer port of the outlet end 21 is provided with a rounded edge. The flared opening or the rounded edge facilitates the quick alignment and fixation when the anti-spray plug 3 is reset, and can further reduce the loss of the anti-spray hole 2 when the anti-spray plug 3 is opened, increasing the service life of the product.

[0045] Further set as: a limiting post 43 is provided on the button body 4, and a fixing groove 15 is provided on the cup cover body. The elastic member 6 is preferably a spring. One end of the spring is arranged in the fixing groove 15, and the other end of the spring is sleeved on the limiting post 43. The elastic member 6 makes the anti-spray plug 3 in a pre-compressed state against the outlet end 21 of the anti-spray hole 2. By installing the elastic member 6, the anti-spray plug 3 is in a pre-compressed state against the outlet end 21 of the anti-spray hole 2. When the straw 91 is in use, the anti-spray hole 2 is also blocked by the anti-spray plug 3, preventing liquid from leaking out of the anti-spray hole 2 during use.

[0046] Further set as: a flip cover is hingedly arranged on the cup cover body, and the flip cover is buckled with the button device. When the button device is pressed, the flip cover is disengaged from the button device. After the flip cover is opened, the anti-spray plug 3 seals the outlet end 21 of the anti-spray hole 2. Through the buckling setting of the flip cover and the button device, the button device opens the flip cover while opening the anti-spray hole 2. After the flip cover is opened, the button device resets to seal the anti-spray hole 2, preventing liquid from leaking out of the anti-spray hole 2 during use.

[0047] In this embodiment, the cup cover body includes a lower cup cover body 11 and an upper cup cover body 12 covering the lower cup cover body 11. The anti-spray hole 2 is arranged on the lower cup cover body 11. A flip cover is hingedly arranged on the upper cup cover body 12. The flip cover includes a hinged cover 71 provided with a fixing hole for the straw 91 and hinged to the upper cup cover body 12, and a fixing cover 72 hinged to one end of the hinged cover 71 and buckled to the button body 4 at the other end. A straw installation hole is arranged on the lower cup cover body 11. The straw 91 passes through the straw installation hole and is fixed to the straw fixing hole. A silicone nozzle 9 is arranged at one end of the straw 91. One end of the nozzle 9 is fixed to the straw installation hole, and the other end of the nozzle 9 is fixed in the straw fixing hole, facilitating the installation and fixation of the straw 91 on the cup cover body. Press the button body 4 to disengage the fixing cover 72 from the button body 4. Due to the elasticity of the nozzle 9 itself, the fixing cover 72 and the hinged cover 71 are flipped open, and the fixing cover 72 is flipped relative to the hinged cover 71, exposing the nozzle 9 for the user to use. When closing, flipping the fixing cover 72 drives the hinged cover 71 to bend the nozzle 9 and then store it in the accommodation cavity of the upper cup cover body 12, and the fixing cover 72 is buckled and fixed to the button body 4.

[0048] Meanwhile, an activity channel is formed between the upper cup cover body 12 and the lower cup cover body 11. The button device moves horizontally within the activity channel. By arranging the button device within the activity channel, the structural space within the cup cover body is rationally utilized, and it also facilitates the stable horizontal movement of the button device within the cup cover body.

[0049] To facilitate the snap-fastening of the button body 4 and the fixed cover 72, the button body 4 is connected in a two-piece split manner. The button body 4 includes an operation section 41 and a fixed section 42 connected to the operation section 41. A first snap-fastening member is provided on the fixed section 42, and a second snap-fastening member that engages with the first snap-fastening member is provided on the fixed cover 72. In the fixed state, the first snap-fastening member and the second snap-fastening member are engaged. Pressing the operation section 41 causes the fixed section 42 to move horizontally, resulting in the separation of the first snap-fastening member and the second snap-fastening member. The fixing post 5 is arranged on the fixed section 42, and the segmented arrangement facilitates production and installation. At the same time, the outlet end 21 of the anti-spray hole 2 is opposite to the orientation of the operation section 41. The outlet end 21 of the anti-spray hole 2 faces inward and is away from the operation section 41.

[0050] It is further set that: an air vent hole 13 communicating with the outside is also provided on the cup cover body. A vent plug 8 is sleeved on the lower port of the air vent hole 13. A vent slit 81 is provided at the end of the vent plug 8. The cooperation of the air vent hole 13 and the vent slit 81 on the vent plug 8 enables the air pressure inside the cup to reach equilibrium when the straw 91 absorbs water, facilitating water absorption. A through hole 14 corresponding to the air vent hole 13 is provided on the upper cup cover body 12, and a through groove is provided on the fixed section 42. When the button assembly is in a static state, the vent slit 81, the through hole 14, and the through groove are connected. When the button assembly is pressed, the through groove on the fixed section 42 moves horizontally and is misaligned with the vent slit 81 and the through hole 14, preventing them from communicating. This can avoid the direct ejection of the internal air pressure from the through hole 14 at the moment of opening and also enable the external air pressure to smoothly enter the cup interior when the straw 91 absorbs water.

[0051] The above embodiments are only the preferred embodiments of the present invention and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
