Description

Technical Field

[0001] This utility model belongs to the field of household products technology, specifically relating to a child-proof bowl lid that prevents children from putting their hands in it and spilling food. Background Technology

[0002] Because children are active and their behavior is highly unpredictable, when using traditional bowls for meals, the traditional bowl lids rely on only a single sealing ring, which often causes the bowl to spill. When pressed, the lid can easily fall off the rim of the bowl, allowing fingers to get in. Furthermore, without an anchoring system, the liquid can easily shift when the bowl is being carried, causing the lid to shift or the liquid inside the bowl to spill out, resulting in spills, splashes, or even burns. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned technical problems and provide a child-proof bowl lid that prevents children from putting their hands in it and spilling food.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A child-proof, spill-proof bowl lid includes a bowl lid body, a three-way skirt structure, and a strap anchoring system, wherein the bowl lid body is embedded in the bowl body;

[0006] The three-way skirt structure includes a horizontal sealing section, an outer wrapping section, and an inner section. The lower end of the inner section is fixedly connected to the edge of the bowl lid body, the upper end of the inner section is connected to one end of the horizontal sealing section, and the other end of the horizontal sealing section is connected to the upper end of the outer wrapping section. The outer wrapping section, the horizontal sealing section, and the inner section together form an Ω-shaped structure, which is fastened to the rim of the bowl body.

[0007] A drinking spout is provided at one end of the bowl lid body, and an air inlet is provided on the bowl lid body directly opposite the drinking spout.

[0008] The sling anchoring system includes several slings and an annular belt. The slings are evenly distributed on the outer wall of the bowl body 1. The upper end is connected to the lower end of the outer wrapping section, and the lower end is connected by the annular belt. The slings are in close contact with the outer wall of the bowl body in their natural state. The elastic modulus of the slings is 2-4 MPa. After stretching, they generate a preload of 8-12 N, so that the Ω-shaped structure forms an interference fit with the edge of the bowl.

[0009] Furthermore, the bowl lid body is inclined, with the drinking spout side lower and the air inlet side higher, and the angle α between the bowl lid body and the horizontal plane is 5-7°.

[0010] Furthermore, the drinking spout is a rectangular opening of 4.0-5.0cm × 2.0-2.5cm, the distance between the drinking spout and the rim of the bowl is 2-3cm, and the size of the air inlet is 0.3-0.8mm × 8-12mm.

[0011] Furthermore, the annular band is located on the outer wall of the bowl at a height of 2 / 3 to 4 / 5 of the bowl's bottom.

[0012] Furthermore, the number of slings is 3-5.

[0013] Furthermore, a ring of anti-overflow rim is provided at the bottom edge of the bowl lid body.

[0014] Furthermore, a guide rim is provided on the bottom surface of the bowl lid body at the edge of the drinking spout, and the outer side of the guide rim is an inclined surface with an inclination angle of 10-20°.

[0015] Furthermore, the horizontal sealing section, the outer wrapping section, and the inner section are connected by a corrugated wall.

[0016] Furthermore, the horizontal sealing section, the outer wrapping section, and the inner embedding section are made of platinum vulcanized silicone or thermoplastic polyurethane, the sling is made of any thermoplastic elastomer material, and the annular belt is made of diatomaceous earth reinforced polymer.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model uses the radial force of the corrugated wall of the Ω-shaped three-way skirt structure and the pre-tightening force of the strap to form a spatial vector resultant force, thereby achieving a double-level locking of the bowl lid. This significantly improves the anti-side-lifting force compared to traditional bowl lids, preventing the bowl lid from falling off and avoiding children's fingers from getting stuck and causing burns or liquid splashing.

[0019] 2. The Ω-shaped three-way skirt structure of this utility model can tightly clamp the rim of the bowl, and block the migration path of the liquid through physical isolation and curvature self-adaptation. At the same time, it can fix the bowl lid body to prevent children from pressing one side and causing the bowl lid to lift up.

[0020] 3. The sling anchoring system of this utility model generates pre-tightening force, further improving the stability of the three-way skirt structure and the bowl lid body;

[0021] 4. The inclined design of the bowl lid body, together with the guide eaves, enables the return of residual liquid on the bottom surface of the bowl lid body, maximizing the liquid return efficiency, significantly reducing the amount of residue on the bottom surface of the bowl lid, and reducing waste.

[0022] 5. The outer wrapping section of this utility model contains diatomaceous earth, and the wet friction coefficient reaches 0.70-0.75, which not only prevents children from accidentally opening it, but also does not affect the one-handed operation of adults. Attached Figure Description

[0033] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0034] like Figure 1-8 As shown, a child-proof bowl lid that prevents hands from entering and spilling includes a bowl lid body 2, a three-way skirt structure 5, and a strap anchoring system, wherein the bowl lid body 2 is embedded in the bowl body 1;

[0035] The three-way skirt structure 5 includes a horizontal sealing section 5.1, an outer wrapping section 5.2, and an inner section 5.3. The lower end of the inner section 5.3 is fixedly connected to the edge of the bowl lid body 2, and the upper end of the inner section 5.3 is connected to one end of the horizontal sealing section 5.1. The other end of the horizontal sealing section 5.1 is connected to the upper end of the outer wrapping section 5.2. The outer wrapping section 5.2, the horizontal sealing section 5.1, and the inner section 5.3 together form an 'Ω' shaped structure, which is fastened to... On the rim of the bowl body 1, the horizontal sealing section 5.1, the outer wrapping section 5.2, and the inner embedded section 5.3 are connected by a corrugated wall. The corrugated wall deforms under pressure, generating a radial elastic force F≥5N. The outer wrapping section 5.2 is doped with 15% diatomaceous earth with an average particle size of 20μm, and its wet friction coefficient μ=0.75 is close to that of shark teeth μ=0.85. The horizontal sealing section 5.1, the outer wrapping section 5.2, and the inner embedded section 5.3 are made of platinum vulcanized silicone.

[0036] The bowl lid body 2 has a drinking spout 4 at one end. An air inlet 3 is provided on the bowl lid body 2 opposite to the drinking spout 4. The bowl lid body 2 is tilted, with the drinking spout 4 side lower and the air inlet 3 side higher. The angle α between the bowl lid body 2 and the horizontal plane is 6°. The drinking spout 4 is a rectangular opening of 4.5cm × 2.2cm. The distance between the drinking spout 4 and the rim of the bowl body 1 is 2.7cm. The size of the air inlet 3 is 0.5mm × 10mm. An anti-overflow rim 8 is provided at the bottom edge of the bowl lid body 2. A flow guide rim 9 is provided on the bottom surface of the bowl lid body 2 at the edge of the drinking spout 4. The outer side of the flow guide rim 9 is an inclined surface with an angle of 15°. The inclination angle of the flow guide rim 10°-20° can prevent children from choking due to the liquid flow rate being too fast when drinking.

[0037] The sling anchoring system includes three slings 6 and an annular belt 7. The slings 6 are made of TPE, and the annular belt 7 is made of diatomaceous earth reinforced polymer.

[0038] The three suspenders 6 are evenly distributed on the outer wall of the bowl body 1. The upper end is connected to the lower end of the outer wrapping section 5.2, and the lower end is connected by the annular belt 7. The suspenders 6 are in close contact with the outer wall of the bowl body 1 in their natural state. The elastic modulus of the suspenders 6 is 2-4MPa. After stretching, they generate a preload of 8-12N, so that the Ω-shaped structure forms an interference fit with the edge of the bowl. The annular belt 7 is located at 2 / 3 of the height from the bottom of the bowl body 1 on the outer wall of the bowl body 1.

[0039] The preload comparison experiment is shown in Table 1. The test method refers to GB / T 5009.156-2016 "Test for Sealing Performance of Food Containers". The Ω-type structure parameters are fixed, and only the preload of the slings is changed.

[0040] Table 1. Results of Preload Comparison Experiment

[0041] Preload (N) Side-lift resistance (N) Liquid spillage rate (%) Child bowl drop rate (%) ≤6 8.2 15.7 38.5 8-12 ≥14.5 ≤2.1 0 ≥14 15.1 1.9 0

[0042] The test results show that when the preload is 8-12N (elastic modulus 2-4MPa), the anti-tipping force and anti-splashing performance are optimally balanced while ensuring the comfort of children holding the bowl with one hand (pressure ≤0.3MPa). When the preload is <8N, the lid is easy to lift, while when the preload is >12N, the ring belt is prone to excessive contraction, requiring adult assistance to disassemble.

[0043] The horizontal sealing section 5.1, the outer wrapping section 5.2, and the inner embedding section 5.3 can also be made of thermoplastic polyurethane, and the sling 6 can be made of any thermoplastic elastomer material.

[0044] The elastic modulus of the sling 6 can also be any value between 2 and 4 MPa, and it generates a preload force of 8-12 N after stretching.

[0045] The angle α between the bowl lid body 2 and the horizontal plane can also be any value between 5° and 7°;

[0046] The annular band 7 can also be located at any height between 2 / 3 and 4 / 5 of the bottom of the bowl from the outer wall of the bowl body 1.

[0047] The number of the slings 6 can also be any value between 3 and 5;

[0048] The outer surface of the guide vane 9 is an inclined surface, and the inclination angle can be any value between 10-20°.

[0049] In this embodiment, bowls with rim thicknesses of 5mm, 8mm, and 10mm were tested to assess the clamping effect of the Ω-shaped structure. The test results are as follows:

[0050] Table 2 Test results of Ω-shaped structure

[0051] Bowl rim thickness Liquid barrier Anti-lift force N 5mm 99.2% 15.3 8mm 98.7% 14.1 10mm 97.5% 12.6

[0052] The test results show that corrugated walls and Ω-shaped structures can provide maximum barrier to liquids.

[0053] The inventors conducted comparative experiments using the present invention (Group C) with traditional flat sealing ring bowl lids (Group A) and single Ω-shaped sealing bowl lids (Group B). Six children aged 2-8 years were divided into three groups for testing, with each child in each group being tested 30-50 times. The average results of each group were taken, and the experimental results are shown in Table 3.

[0054] Table 3 Comparison of experimental results

[0055] Test Project Group A Group B Group C Side-lift force N ≤5.2 8.7 ≥14.5 Liquid spillage rate % 38.2 12.4 ≤2.1 Number of times the bowl fell off while walking 33 times / 50 times 14 times / 50 times 0 times / 50 times

[0056] The comparative experimental results show that the performance of this invention in terms of anti-side lifting force, liquid spillage rate, and number of times the bowl falls off while walking is far superior to that of similar traditional products. This is because the radial pre-tightening force provided by the sling system and the axial clamping force of the Ω-shaped structure form a resultant force F, which can greatly improve the performance of this invention.

[0057] The working process of this utility model:

[0058] In use, parents place the desired milk, porridge, or other liquid food into the child's bowl 1. They then open the annular strap 7 with both hands, pass it through the bowl's rim, and release it. The annular strap 7 elastically contracts, tightly fitting around the lower part of the bowl 1. Simultaneously, the three straps 6 tightly wrap around the outer wall of the bowl 1. Next, the three-way skirt structure 5 is pressed and secured to the rim of the bowl. At this point, the outer wrapping section 5.2 is located on the outside of the rim, the horizontal sealing section 5.1 is on the top surface of the rim, and the inner section 5.3 is on the inside of the rim. Under the tightening force of the straps 6, the three-way skirt structure 5'Ω' is tightly secured to the rim, forming a micro-gap channel. The anti-slip serrations on the bottom surface of the horizontal sealing section 5.1 are in close contact with the rim, blocking the liquid's migration path. When drinking, the child picks up the bowl and drinks through the drinking spout 4. Air enters through the air inlet 3 on the other side, keeping the internal and external pressures consistent. This ensures that the liquid can flow smoothly from the drinking spout 4, which is sized to fit a child's mouth. On the other hand, the lid body 2 prevents children from sticking their fingers into the bowl 1, avoiding burns. Furthermore, the lid body 2 is connected to the three-way skirt structure 5 around its perimeter, preventing children from prying it open by pressing one side. The lid body 2 is tilted, so after drinking and placing it flat, the liquid adhering to the bottom of the lid body 2 flows along the tilted surface towards the drinking spout 4. Finally, the guide eaves 9 break the kinetic energy of the droplets, causing them to fall back into the bowl 1. When a child randomly touches the bowl 1, the liquid inside shakes. When the liquid shakes and touches the anti-overflow eaves 8, it acts as a barrier, preventing the liquid from splashing out.
