[0034] like Figure 1 As shown, this exemplary embodiment provides a tooth glue, comprising:

[0035] The hand-held part 300, the arc-shaped sheet-shaped blocking part 200 and the glue head part 100;

[0036] The hand-held part 300 and the rubber head part 100 are respectively arranged on two side surfaces of the arc-shaped sheet-shaped blocking part 200;

[0037] At least one slit 210 is disposed on the arc-shaped sheet-shaped blocking portion 200 . The slit 210 extends from the edge of the arc-shaped sheet-shaped blocking portion 200 to the intersection of the arc-shaped sheet-shaped blocking portion 200 and the hand-held portion 300 .

[0038] like Figure 1 As shown, in the embodiment of the present application, the hand-held portion 300, the arc-shaped sheet-shaped blocking portion 200 and the rubber head portion 100 can all be made of soft silicone material, wherein the hand-held portion 300 is roughly cylindrical, the arc-shaped sheet-shaped blocking portion 200 is roughly umbrella-shaped, and the rubber head portion 100 is roughly nipple-shaped. It should be noted that in order to facilitate the gripping of infants and young children, in another embodiment, the hand-held portion 300 can also be roughly in the shape of a pull ring, and the present application does not limit the specific structure of the hand-held portion 300.

[0039] Continue to refer to Figure 1 In the embodiment of the present application, the two side surfaces of the arc-shaped sheet-shaped barrier 200 are respectively the concave surface and the convex surface of the arc-shaped sheet-shaped barrier 200; the hand-held portion 300 can be arranged on the concave surface 230 of the arc-shaped sheet-shaped barrier 200, and the rubber head portion 100 can be arranged on the convex surface of the arc-shaped sheet-shaped barrier 200. In other embodiments, the hand-held portion 300 can also be arranged on the convex surface of the arc-shaped sheet-shaped barrier 200, and the rubber head portion 100 can also be arranged on the concave surface 230 of the arc-shaped sheet-shaped barrier 200. The present application does not limit the arc bending direction of the arc-shaped sheet-shaped barrier 200.

[0040] Reference Figure 1 , Figure 2 As shown, in the embodiment of the present application, the hand-held portion 300 is arranged on the concave surface 230 of the arc-shaped sheet-shaped barrier portion 200, and the gum head portion 100 is arranged on the convex surface of the arc-shaped sheet-shaped barrier portion 200. Among them, one end of the hand-held portion 300 is connected to the concave surface 230 of the arc-shaped sheet-shaped barrier portion 200, so that the arc-shaped sheet-shaped barrier portion 200 can be covered on the top of the hand-held portion 300, and the gum head portion 100 is connected to the convex surface of the arc-shaped sheet-shaped barrier portion 200. When the infant holds the hand-held portion 300 and bites the gum head portion 100, the mouth and teeth are located on one side of the arc-shaped sheet-shaped barrier portion 200, and the hand is located on the other side of the arc-shaped sheet-shaped barrier portion 200. The arc-shaped sheet-shaped barrier portion 200 can separate the hand and the teeth, and the arc-shaped sheet-shaped barrier portion 200 can also play a limiting role, which can prevent the infant from inserting the gum too deep into the mouth. In addition, the arc-shaped sheet-like blocking portion 200 can also cover the hands of infants and young children under its concave surface 230, thereby preventing infants and young children from chewing or biting their hands.

[0041] Continue to refer to Figure 1 In the embodiment of the present application, the arc-shaped sheet-like blocking portion 200 intersects with the hand-held portion 300 at the vertex position of the arc-shaped sheet-like blocking portion 200, that is, the hand-held portion 300 can be arranged at the position where the vertex of the concave surface 230 of the arc-shaped sheet-like blocking portion 200 is located, and the rubber head portion 100 can be arranged at the position where the vertex of the convex surface of the arc-shaped sheet-like blocking portion 200 is located. The hand-held portion 300 and the rubber head portion 100 can be coaxially arranged, so that it is convenient for infants and young children to hold the hand-held portion 300 to determine the position of the rubber head portion 100 when using it, so that they can easily put the rubber head portion 100 into their mouths.

[0042] Continue to refer to Figure 1 In the embodiment of the present application, a slit 210 is provided on the arc-shaped sheet-shaped barrier 200, and the opening of the slit 210 is located on the edge of the arc-shaped sheet-shaped barrier 200 and extends toward the vertex of the arc-shaped sheet-shaped barrier 200. It should be noted that the slit 210 runs from the convex surface of the arc-shaped barrier 200 to the concave surface 230 thereof, and the entire slit 210 is continuous in the extending direction of the slit 210. In addition, the opening of the slit 210 mentioned in the present application refers to the opening of the slit 210 at the edge of the arc-shaped barrier 200, that is, the starting position of the slit at the edge of the arc-shaped barrier 200.

[0043] In the embodiment of the present application, the arc-shaped sheet-like blocking portion 200 is bent toward the hand-holding portion 300. When in use, the infant holds the hand-holding portion 300. When the infant moves the hand, the concave surface 230 of the arc-shaped sheet-like blocking portion 200 will be subjected to the force of the hand. Since the arc-shaped sheet-like blocking portion 200 is provided with a slit 210, when the arc-shaped sheet-like blocking portion 200 is subjected to force, the slit 210 will open, so that the arc-shaped sheet-like blocking portion 200 is separated from the slit 210. At this time, the arc-shaped sheet-like blocking portion 200 can be deformed into a shape that adapts to the movement of the infant's hand without restraining the infant's hand inside the arc-shaped blocking portion 200, thereby improving the comfort of use.

[0044] In addition, when the hand-held portion 300 is arranged on the concave surface of the arc-shaped sheet-like barrier portion 200 and the rubber head portion 100 is arranged on the convex surface of the arc-shaped sheet-like barrier portion 200, when the arc-shaped sheet-like barrier portion 200 is turned toward the side of the rubber head portion 100, since the arc-shaped sheet-like barrier portion 200 is provided with a slit 210, the stress of the arc-shaped sheet-like barrier portion 200 itself is disconnected at the slit 210, so the arc-shaped sheet-like barrier portion 200 will automatically rebound, that is, automatically turn toward the side of the hand-held portion 300; in addition, since the slit 210 on the arc-shaped sheet-like barrier portion 200 can make the arc-shaped sheet-like barrier portion 200 automatically rebound and cover a part of the hand-held portion 300, it can avoid that the hand-held portion 300 is excessively exposed to the outside due to the arc-shaped sheet-like barrier portion 200 turning toward the rubber head portion 100, thereby preventing infants and young children from excessively putting the hand-held portion 300 into their mouths in the event of misoperation.

[0045] When the hand-held portion 300 is arranged on the convex surface of the arc-shaped sheet-like blocking portion 200, and the rubber head portion 100 is arranged on the concave surface of the arc-shaped sheet-like blocking portion 200, since the arc-shaped sheet-like blocking portion 200 is provided with a slit 210, the arc-shaped sheet-like blocking portion 200 will not be completely sucked onto the infant's mouth, and it is difficult to form a closed space between the arc-shaped sheet-like blocking portion 200 and the infant's mouth, thereby avoiding breathing difficulties for the infant.

[0046] It should also be noted that Figure 1 The gutta-percha shown is only provided with one slit 210 . In other embodiments, two, three, or more slits 210 may be provided. The present application does not impose any limitation on the specific number of the slits 210 .

[0047] In the embodiment of the present application, by providing at least one slit 210 on the arc-shaped sheet-like blocking portion 200, on the one hand, when the arc-shaped sheet-like blocking portion 200 is turned to the other side, it can automatically rebound; on the other hand, it can effectively prevent the arc-shaped sheet-like blocking portion 200 and the infant's mouth from forming a closed space and being sucked on the infant's mouth, thereby preventing the infant from having breathing difficulties; on another hand, when the hand-holding portion is provided on the concave surface of the arc-shaped sheet-like blocking portion 200, the arc-shaped blocking portion can open the slit 210 as the infant's hand moves, and be deformed into a shape that adapts to the infant's hand movements, thereby improving the comfort of use.

[0048] like Figure 2 As shown in the embodiment of the present application, the concave surface 230 of the arc-shaped sheet-shaped blocking portion 200 is provided with a thickened portion 250 at the apex of each slit 210. Figure 2For example, a tooth gel in which a slit 210 is provided, the arc-shaped sheet-shaped blocking portion 200 is provided with a thickened portion 250 at the vertex where the slit 210 extends, that is, at the position of the other end of the slit 210 relative to its own opening, and the thickened portion 250 is provided on one side of the concave surface 230. During use, infants and young children may tear the tooth gel along the slit 210. The thickened portion 250 is provided at the vertex where the slit 210 extends, which can improve the tear resistance of the vertex where the slit 210 extends.

[0049] like Figure 2 As shown, in the embodiment of the present application, the thickened portion 250 is provided with a through hole 220, and the through hole 220 penetrates the arc-shaped sheet-like barrier portion 200, and the slit 210 extends into the through hole 220. Specifically, the through hole 220 penetrates the arc-shaped sheet-like barrier portion 200 along the thickness direction of the arc-shaped sheet-like barrier portion 200. When the arc-shaped sheet-like barrier portion 200 is torn along the slit 210, the tearing force will eventually be concentrated at the vertex of the extension of the slit 210, and the vertex position of the extension of the slit 210 is easy to be torn. The through hole 220 is provided on the thickened portion 250. When the tearing force reaches the vertex position of the extension of the slit 210, it will be dispersed to the inner side wall 221 of the through hole 220, so as to disperse the stress at the extension vertex position of the slit 210, avoid excessive concentration of stress, and further improve the tear resistance of the arc-shaped sheet-like barrier portion 200.

[0050] In addition, when the tearing force reaches the apex of the extension of the slit 210, a part of the tearing force will be converted into a force to open the through hole 220 and expand it. Figure 2 As shown, when the tearing force reaches the positions of points A and B, a part of the tearing force will be converted into a force that increases the distance between points A and B. Only after the through hole 220 is opened to a certain extent, that is, the distance between points A and B increases to a certain extent, will the tearing force further concentrate on the inner wall 221 of the through hole 220. At this time, a part of the tearing force has been offset. Therefore, the through hole 220 is provided at the vertex of the extension of the slit 210, which can also play a role in offsetting the tearing force.

[0051] like Figure 2 As shown, in the embodiment of the present application, the diameter of the through hole 220 is greater than the width of the slit 210. Setting the diameter of the through hole 220 to be greater than the width of the slit 210 can improve the ability of the through hole 220 to offset the tearing force, that is, when the tearing force reaches the position of the through hole 220, most of the tearing force will be converted into a force to expand the through hole 220, thereby preventing the arc-shaped sheet-shaped blocking portion 200 from being torn.

[0052] like Figure 2As shown, in the embodiment of the present application, the inner side wall 221 of the through hole 220 extends along the thickness direction of the arc-shaped sheet-like barrier 200. After the tearing force along the slit 210 reaches the position of the through hole 220, a part of it is converted into a force to open the through hole 220. After the through hole 220 is opened, the remaining tearing force continues to concentrate on the inner side wall 221 of the through hole 220. The inner side wall 221 of the through hole 220 is parallel to the thickness direction of the arc-shaped sheet-like barrier 200, and the tearing force is perpendicular to the thickness direction of the arc-shaped sheet-like barrier 200, that is, the remaining tearing force is perpendicular to the inner side wall 221 of the through hole 220, so that the inner side wall 221 of the through hole 220 perpendicular to the tearing force can play a role in blocking the tearing force.

[0053] like Figure 3 As shown, in the embodiment of the present application, the inner side wall 221 of the through hole 220 includes a first arc surface 260 and a second arc surface 261 connected to the slit 210, and a third arc surface 262 disposed between the first arc surface 260 and the second arc surface 261, the third arc surface 262 is smoothly connected to the first arc surface 260 and the second arc surface 261, the radius of the third arc surface 263 is greater than the radius of the first arc surface 260, and the radius of the third arc surface 262 is greater than the radius of the second arc surface 261. Figure 3 As shown, the inner side wall 221 of the through hole 220 is connected to the two side walls forming the slit 210, and the inner side wall 221 of the through hole 220 can be divided into three sections: the first arc surface 260 and the second arc surface 261 located at the two ends, and the third arc surface 262 located in the middle, the first arc surface 260 and the second arc surface 261 are connected to the two side walls forming the slit 210, and the third arc surface 262 is smoothly connected to the first arc surface 260 and the second arc surface 261, wherein the radius of the third arc surface 262 located in the middle is greater than the radius of the first arc surface 260 and the radius of the second arc surface 261 at the two ends, so that it can have a strong tear resistance. In another embodiment, the radius of the first arc surface 260 and the radius of the second arc surface 261 can also be set to be the same, so that when the tearing force extends along the slit 210 to the through hole 220, it can be evenly distributed to the first arc surface 260 and the second arc surface 261.

[0054] like Figure 4 As shown, in the embodiment of the present application, the plane where the slit 210 is located passes through the axis of the gutta-percha. When the slit 210 is set, it can be extended from any position of the edge of the arc-shaped sheet-shaped blocking portion 200 to the vertex, and its extension path can be extended according to the shortest distance, that is, the plane where the slit 210 is located passes through the axis of the gutta-percha. Figure 4As shown, the dotted line L1 is the axis of the gutta-percha, and the plane (vertical plane) where the slit 210 is located passes through the axis. In other embodiments, the extension may not be made according to the shortest distance. For example, it may be extended spirally around the gutta-percha axis L1 starting from the edge starting point of the arc-shaped sheet-shaped barrier 200. Compared with the two extension methods, for the method in which the slit 210 is extended spirally around the gutta-percha axis, when the infant's hand moves under the concave surface 230 of the arc-shaped sheet-shaped barrier 200, the arc-shaped sheet-shaped barrier 200 needs to be deformed along the spirally extended slit 210, which is inconvenient; if the slit 210 is extended in a manner that the plane where the slit 210 is located passes through the axis of the gutta-percha, when the infant's hand moves under the concave surface 230 of the arc-shaped sheet-shaped barrier 200, the arc-shaped sheet-shaped barrier 200 can be easily changed to a shape that adapts to the hand following the movement of the infant's hand, thereby providing a better user experience.

[0055] like Figure 5 As shown, in the embodiment of the present application, the plane where the slit 210 is located is the section of the gutta-percha, and on this section, the length of the arc where the slit 210 is located is not less than 1 / 3 of the length of the arc from the opening of the slit 210 to the vertex of the arc-shaped sheet-shaped blocking portion 200. Figure 5 As shown, in the embodiment of the present application, the dotted line L2 is an arc line from the opening of the slit 210 to the vertex position of the arc-shaped sheet-shaped blocking portion 200, with the plane where the slit 210 is located as the section plane. Then, the length of the dotted line L2 from the opening of the slit 210 to the position of the through hole 220 is not less than 1 / 3 of the total length of the dotted line L2. With this arrangement, when the arc-shaped sheet-shaped blocking portion 200 turns over toward the rubber head portion 100, it can easily rebound and turn over toward the hand-held portion 300 under the action of its own stress.

[0056] like Figure 2 As shown, in the embodiment of the present application, a plurality of reinforcing ribs 240 are provided on the concave surface 230 of the arc-shaped sheet-shaped blocking portion 200, and the reinforcing ribs 240 extend from the apex of the concave surface 230 to the edge of the concave surface 230. In the embodiment of the present application, the reinforcing ribs 240 surround the apex of the concave surface 230 of the arc-shaped sheet-shaped blocking portion 200 and extend from the apex of the concave surface 230 to the edge of the concave surface 230. The reinforcing ribs 240 are provided on the concave surface 230, which can enhance the strength of the arc-shaped sheet-shaped blocking portion 200 on the one hand, and enhance the ability of the arc-shaped sheet-shaped blocking portion 200 to automatically rebound after turning over to the rubber head 100 on the other hand.

[0057] like Figure 2As shown, in the embodiment of the present application, in the thickness direction of the arc-shaped sheet-shaped blocking portion 200, the thickness of the reinforcing rib 240 is the same as the thickness of the thickened portion 250. Setting the thickness of the reinforcing rib 240 to be the same as the thickness of the thickened portion 250 can, on the one hand, avoid generating a large local stress at the junction of the reinforcing rib 240 and the thickened portion 250; on the other hand, it can also avoid generating high and low convexities and concavities due to the different thicknesses of the reinforcing rib 240 and the thickened portion 250, which may cause discomfort to the hands of infants and young children.

[0058] like Figure 1 As shown, in the embodiment of the present application, the thickness of the arc-shaped sheet-shaped blocking portion 200 gradually decreases from the intersection of the arc-shaped sheet-shaped blocking portion 200 and the hand-held portion 300 to the edge. The wall thickness of the arc-shaped sheet-shaped blocking portion 200 gradually decreases from the vertex position, so that the edges around are thinner and the top in the middle is thicker, so that it is not easy to flip to the side of the chewing gum 100.

[0059] In the embodiment of the present application, at least one slit 210 is provided on the arc-shaped sheet-shaped barrier 200. On the one hand, when the arc-shaped sheet-shaped barrier 200 is turned to the other side, it can automatically rebound; on the other hand, it can effectively prevent the arc-shaped sheet-shaped barrier 200 and the infant's mouth from forming a closed space and being sucked on the infant's mouth, thereby preventing the infant from having difficulty breathing. On the other hand, the arc-shaped sheet-shaped barrier 200 can open the slit 210 as the infant's hand moves, and deform into a shape that adapts to the infant's hand movements, thereby improving the comfort of use.

[0060] Finally, it should be noted that the above embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them. The protection scope of the present application is not limited thereto. Although the present application is described in detail with reference to the above embodiments, ordinary technicians in the field should understand that any technician familiar with the technical field can still modify the technical solutions recorded in the above embodiments within the technical scope disclosed in the present application, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
