Description

A direct drinking nozzle that is bite-proof, suck-proof, flow-controlled, mouth-loosening-proof, and bite-assisted Technical Field

[0001] The present invention relates to the field of infant and child products, and more specifically, to a device that can be assembled with a straw, such as any straw cup, thermos cup, or feeding bottle with a straw function. More specifically, the present invention relates to a direct drinking nozzle that is bite-proof, anti-sucking, flow-controlled, anti-slip, and assists in biting. Background Art

[0002] Direct drinking nozzles are used in baby and infant feeding products, such as water cups, feeding bottles, and thermos cups. They involve fluidics, pneumatics, soft rubber materials (TPE, silicone, etc.), and ergonomics.

[0003] Existing products mainly involve two functional directions, namely, anti-overflow nozzles and anti-overflow nozzles.

[0004] Overflow prevention usually refers to a "V"-shaped valve nozzle (as shown in Figure 1), which has a "V"-shaped diaphragm in the middle with an "I"-shaped incision cut in the middle. When the nozzle's soft rubber is deformed under force, the "I"-shaped silicone diaphragm is squeezed, opening the incision and allowing water to flow through. At the same time, this sharp-angled design can prevent the cup container from being sprayed by the pressure difference after being placed in hot water (100°C).

[0005] Overflow prevention usually refers to a micro-valve nozzle (as shown in Figure 2). The original "V"-shaped diaphragm in the middle is transformed into a sphere and arc surface, and the sharp angle design is eliminated. The overall diaphragm is relatively round, which makes the force less and can discharge water. An "I"-shaped incision is cut in the middle. After the soft rubber of the nozzle is deformed under force, the silicone diaphragm of the "I"-shaped incision is squeezed and the incision is opened to allow water to flow through. Compared with anti-overflow, the nozzle with this structure requires less force from the user and drinking water is smoother, but at the same time, the effect of spraying due to the pressure difference generated by high-temperature water is slightly worse by about 30°C.

[0006] The existing patents mainly focus on the design, innovation and protection of "overflow"; and the products are mainly sold to solve the problem of overflow spray after adding hot water;

[0007] However, the following problems were found in actual use, affecting the normal use of users:

[0008] 1. As shown in Figures 1 and 2, the cross-section of a typical direct drinking nozzle is a runway circle, with the short side in the same direction as the nozzle opening and the long side at a 90-degree angle to the nozzle opening. The upper and lower lips are in the direction of force applied to the nozzle, and the upper and lower arcs of the short side are squeezed, tending to be flat. This has a minimal impact on tooth development and is the easiest way to deform the nozzle. Therefore, 90% of current nozzle designs are of this type. When this type of nozzle is subjected to excessive force, the silicone reaches its limit of deformation, and the upper and lower surfaces of the inner wall come close. Due to the low degree of silicone material and its self-adhesive properties, the two surfaces will temporarily adhere, blocking the water flow channel and preventing water from passing through. Users complain that they cannot absorb water.

[0009] 2. When the baby bites or chews repeatedly, the baby's canine teeth will impact a point on the mouthpiece, causing the mouthpiece to be bitten and thus scrapped;

[0010] 3. This type of nozzle, during the squeezing process, the original elliptical area is sharply reduced to a leaf area, and the overall area is greatly reduced, resulting in a large change in flow rate and a sudden gusher of water, which makes it difficult for the baby to suck water;

[0011] 4. The existing nozzle is easy to fall out of the mouth, causing water to splash out;

[0012] 5. The existing nozzle has only one diaphragm valve and no external indication. When the baby bites in the wrong position, the diaphragm opens without receiving force, resulting in the baby not being able to drink water.

[0073] This embodiment provides a direct drinking nozzle that is bite-proof, anti-sucking, flow-controlled, anti-drop-out, and assisted in biting. The direct drinking nozzle can be used with various containers with straw functions, such as straw cups, straw bottles, etc. The direct drinking nozzle can be an integrated structure of such containers and can be a replaceable consumable accessory structure.

[0074] As shown in FIG3 , the direct drinking nozzle comprises a direct drinking nozzle body 10 and a diaphragm 20. The diaphragm has a one-way mechanism at its center. When the diaphragm is deformed under pressure, the one-way mechanism is opened, thereby achieving the effect of allowing water to flow through. In general, the one-way mechanism is a cutout shape. Various cutout shapes as shown in FIG4 can be applied to the diaphragm of this embodiment, such as straight lines, wavy lines, dots, crosses, T-shaped, Y-shaped, and large letters.

[0075] As shown in FIG5 , the direct drinking nozzle of this embodiment further includes a first reinforcing rib 11 ;

[0076] The first reinforcing rib 11 is provided on the inner wall of the direct drinking nozzle body to form the outer diameter of the diaphragm 20. There are three types of reinforcing ribs:

[0077] In form 1, the first reinforcing rib is only provided at the position corresponding to the diaphragm, or covers the upper and lower positions thereof;

[0078] Form 2: The first reinforcing rib is provided on the diaphragm and from the diaphragm to the outlet of the direct drinking nozzle (i.e., section F in FIG3 );

[0079] In form 3, the first reinforcing rib constitutes the entire inner surface of the direct drinking nozzle (ie, section BF in FIG. 3 ).

[0080] The first reinforcing rib 11 limits the deformation of the diaphragm, so that the diaphragm and the pipe extending upward to the outlet of the direct drinking nozzle body cannot be closed under pressure.

[0081] In this embodiment, the specific structure for achieving the above effect is as follows: the first reinforcing rib 11 is divided by the diaphragm 20, and four silicone arc columns are designed starting from the root of the nozzle, so that the cross-section of the rear half of the nozzle is a "cross"-like area, rather than the original elliptical shape. Through this shape, see the position indicated by the arrow in the figure (i.e., the clutch tips arranged in pairs and protruding inward). When the nozzle is subjected to force, the upper left and lower left silicone of the cross are squeezed together, and the upper right and lower right silicone are squeezed together. Before the inner wall of the nozzle collides and is squeezed, they are squeezed together in advance, dividing the inner pipeline into at least three spaces (as shown in Figure 6), so that the entire inner wall area will not be squeezed together, retaining a channel for water to flow through, thereby solving the problem of being unable to drink water due to the water channel being closed after the self-adhesive suction collapses;

[0082] At the same time, due to the reinforced support ribs inside the nozzle, the thickness of the silicone is thickened in disguise, which can effectively improve the resilience of the silicone, cushion the piercing force of the baby's teeth, and prevent the nozzle from being bitten;

[0083] Furthermore, such a structure can effectively slow down the tearing of the opening on the diaphragm, so that the maximum tearing of the opening remains within the area of ​​our reinforcing ribs, thereby stabilizing the flow rate and preventing it from continuing to increase.

[0084] For this type of cross pattern, the long side, wide side and distance between pairs of clutch tips are in the following ratios: 5±0.5-10±0.5: 3.5±0.5-8.5±0.5: 1.5±0.5-3.5±0.5.

[0085] In this embodiment, five of the above-mentioned cross-shaped patterns are provided, as shown in FIG. 7-1 .

[0102] In one example, the long side of the ellipse of shape A is: 9.50 mm;

[0104] The vertical distance between the support ribs (i.e., the vertical distance between the clutch tips) is: 2.70mm;

[0105] The distance from the clutch tip to the vertex of the adjacent short side in the vertical direction is 2.15 mm.

[0119] The vertical distance between the support ribs (i.e., the vertical distance between the clutch tips) is: 2.31mm;

[0120] The horizontal distance between the clutch tips is 2.13 mm;

[0121] The distance from the clutch tip to the vertex of the adjacent short side in the vertical direction is 2.36 mm.

[0122] In addition, the above-mentioned cross-shaped pattern must also meet the following conditions:

[0123] Condition 1. In the longitudinal direction, the distance between the inner wall of the first reinforcing rib and the inner wall of the direct drinking nozzle is B1;

[0124] In the width direction, the distance between the inner wall of the first reinforcing rib and the inner wall of the direct drinking nozzle is B2;

[0125] The ratio of B2 to B1 is 1:1-3.75.

[0126] Preferably, the B1 is selected from the range of 1.0±0.2-1.8±0.2; and the B2 is selected from the range of 1.5±0.5-2.5±0.5.

[0127] Condition 2: The distance between the tip of the clutch tip of the first reinforcing rib and the inner wall of the direct drinking nozzle (i.e., the normal distance) is B3;

[0128] The distances between B3 and the paired clutch tips were in the following ratios: 3.0±0.5-6.5±0.5: 1.5±0.5-3.5±0.5.

[0129] In addition, based on the above principle of being unable to be flattened, various first reinforcing rib structures with the same function are provided in this embodiment as shown in FIG. 7-2 .

[0130] It can be seen from the figure that the first reinforcing ribs can be as few as one pair or more than two pairs. The core of the structure is a structure with inwardly protruding clutch tips. The clutch tips can be set in opposite directions or in diagonal, staggered or eccentric settings. The purpose is to achieve internal pressure through the collision between the clutch tips or the collision with the inner wall of the opposite surface, so that the entire inner ring cannot be completely closed.

[0131] Therefore, when the outer wall is driven by pressure to transmit force inward, the inner pipeline is divided into at least two spaces by the clutch tips contacting each other or the inner wall, and the one-way mechanism is located in the space that cannot be completely flattened. If there are multiple such spaces, the one-way mechanism can also be set up in multiple corresponding ways.

[0132] In addition, in this embodiment, as shown in the circled position in FIG8 , a spherical surface is slightly concave downward at the center point of the nozzle blade, and the thickness at the center position of the one-way mechanism is thinner than that at other positions.

[0133] Based on this shape, the blade can be slightly opened to allow the internal air pressure to exchange with the external air pressure, and the water column can fall back to prevent the risk of water spraying; it solves the problem of traditional suction nozzles that when water suction stops, the part behind the diaphragm is still full of water. This part of water stays due to the balance of internal and external air pressure, resulting in the suction nozzle being squeezed when the sliding cover is closed, causing some water to spray out.

[0134] FIG8 shows the shape of a V-shaped diaphragm, which is also applicable when the diaphragm is in a corrugated shape.

[0135] In addition, in order to control the flow, this embodiment is implemented through the following design scheme:

[0136] Design Point 1. Limiting deformation effect through reinforcement

[0137] For babies who are younger and use water cups too early, there are risks and problems such as large flow rate and strong throat flushing, which may lead to choking.

[0138] Flow rate formula: ΔQ=S*V, the initial velocity V is the same (the baby's lung capacity remains unchanged, the suction force remains unchanged, and the initial velocity of the water flow remains similar), the size of the cross-sectional area affects the size of the flow rate;

[0139] When the baby sucks water, the traditional nozzle is squeezed and its shape changes, but the cross-sectional area remains constant; therefore, the flow rate at the rear part of the nozzle diaphragm is constant and large; Q1=S1*V

[0140] When passing through the opening of the diaphragm of this embodiment, the deformation of the central cutout area is limited due to the contact of the clutch tip. Therefore, the cross-sectional area is reduced due to the deformation of the blade size, and the flow rate is reduced; Q2 = S2*V (S2<<S1);

[0141] This will make it more difficult for the baby to absorb more water.

[0142] As shown in FIG9 , this embodiment further realizes flow control by limiting the incision, that is, A1:A2=0.8±0.2-3±0.2:0.5±0.2-3±0.2; R1 is 0.8±0.2-5±0.2 mm.

[0143] Design Point 2: Use the second reinforcement rib to limit the water inflow at the rear end

[0144] As shown in FIG10 , the second reinforcing rib 12 is an extension of the first reinforcing rib toward the bottom of the diaphragm;

[0145] The second reinforcing rib 12 covers part or all of the direct drinking nozzle body below the diaphragm (as shown in section B in FIG3 ).

[0146] This structure, by adding a second support rib behind the diaphragm, reduces the cross-sectional area of ​​the pipe behind the diaphragm from the original elliptical shape to area A, which can block the forward flow of water. According to the flow formula, the cross-sectional area is reduced, the suction force (V velocity) remains basically unchanged, and the flow rate is reduced, achieving the first-order flow reduction function.

[0147] At the same time, in combination with the different shapes and structures in front of the diaphragm, the pipe area in front of the diaphragm is changed from the traditional blade area to the new flow area B. The area B is slightly smaller than the area A, but larger than the blade area. It not only ensures the second-order function of reducing the cross-section and reducing the flow rate, making the water absorption process easy and reducing splashing, but also alleviates the problem of too small flow rate and the baby needing to exert force.

[0148] In addition, considering that the outer surface of traditional silicone nozzles is a smooth and flat curved surface, and in a liquid environment, the silicone surface is relatively slippery, most of them are designed with a circle of ribs at the front end to mainly help the lips to be pressed on the nozzle and not easily slip out; the silicone surface treatment - glossy surface will increase friction and can help prevent it from slipping out, but at the same time it will cause the problem of sticking to the mouth, sometimes it can even break the delicate baby's lips and mouth skin; although the existing silicone surface treatment - matte surface solves the problem of silicone being too sticky, it has less friction and cannot help prevent it from slipping out.

[0149] In this embodiment, as shown in FIG3 , the outer surface of the direct drinking nozzle body is designed to resemble a bionic human mouth.

[0150] As shown in Figure 11, the raised arc surface in this area just corresponds to the largest contact area when the baby's lips are placed on the suction nozzle. In this way, when the baby's upper and lower lips are completely fitted together, the body formed by the raised arc surface forms an inverted buckle in the mouth, and the force of dislodging will be increased. In other words, it is not easy for the baby to dislodge when sucking water.

[0151] At the same time, a concave arc surface is made between the center line of the valve (the center axis of the convex part where the diaphragm is located) and the nozzle head. After the teeth touch the arc surface, they naturally move downward along the arc line for a short distance, which is in the best bite range. On the one hand, it is convenient to bite open the nozzle; on the other hand, it cooperates with the wavy surface to prevent the mouth from slipping out.

[0152] The ratio of the distance between the center line of the valve and the outlet of the direct drinking nozzle body (i.e., section F) to the depth of the arc surface concave portion is: 7.5±0.5-12±0.5: 0.5±0.5-1.2±0.5.

[0153] The ratio of the arc surface width of the B segment to the arc surface concave depth below the central axis of the convex portion where the diaphragm is located is 2±0.5-9±0.59:0.5±0.5-4.0±0.5.

[0154] Durability test:

[0155] Refer to GB28482-2012 Safety Requirements for Pacifiers for Infants and Young Children, 7.2.5 Bite Durability Test

[0156] Apply a minimum force of 200N±10N to clamp the nozzle; apply a maximum force of 400N±10N and a minimum force of 200N±10N to the jaws at a speed of (10±1)mm / min. Similar products from companies such as b**, N**, Bei*, and Xin** can only break after about 100 cycles, while the product in this embodiment can break after 200 cycles. This is clearly more durable.
