[0024] The utility model will be further described below in combination with the drawings:

[0025] The directions described in the utility model specification, such as “up”, “down”, “left”, “right”, “front”, “back” and the like, are all based on the directions of the drawings as the reference, and the purpose is to facilitate the description of the relationship between various components, and not to indicate the unique or absolute position relationship between various components, only to realize one of the embodiments of the utility model, and is not a limitation on the embodiment.

[0026] Embodiment one

[0027] The utility model provides a simple structure's material storage type bottle cap, such as Figures 1 to 5As shown, the storage type bottle cap comprises a bottle cap 1, the bottle cap 1 has a material bin barrel 11 with an open upper end for filling materials in the middle, and a cover member 2 connected to the top of the bottle cap 1 for covering the material bin barrel 11. During manufacturing, the materials are first filled into the material bin barrel 11, and then the cover member 2 is assembled to the bottle cap 1, so that the material bin barrel 11 and the cover member 2 enclose a closed storage space for storing mixed materials. In this embodiment, the mixed materials are pre-prepared tea powder, of course, the materials can also be sugar powder, seasonings, etc. Figure 3The cover 2 is connected to the bottle cap 1 around the edge, and the middle of the cover 2 has a press part 21 which can be deformed by pressing with hands. In order to make the press part 21 deformable, the cover 2 can be made of food-grade silica gel, soft plastic or other materials. The press part 21 is connected to a pressing column 22 which can press on the bottom of the hopper barrel 11 when it is pressed down. The pressing column 22 is generally arranged at the center of the press part 21. The bottom of the hopper barrel 11 is provided with a pressure point P at the position corresponding to the pressing column 22. The bottom of the hopper barrel 11 is provided with three bending grooves 12 which are connected at the head and tail to form a regular triangle structure with the pressure point P as the center. Of course, four or more bending grooves 12 can be arranged to form a quadrilateral or other polygonal structure. The bottom of the hopper barrel 11 is also provided with tearable grooves 13 corresponding to the number of bending grooves 12. One end of the tearable groove 13 is communicated with the end point of the bending groove 12, and the other end of the tearable groove 13 extends towards the pressure point P and is communicated with each other around the pressure point P. When the user presses the press part 21 down, the pressing column 22 presses on the bottom of the hopper barrel 11, so that the bottom of the hopper barrel 11 is deformed under stress. After the deformation of the bottom of the hopper barrel 11, stress concentration is first generated at the position of the tearable groove 13, and then the bottom of the hopper barrel 11 is torn along the length direction of the tearable groove 13. Through the above structure, only two components, the bottle cap 1 and the cover 2, are needed to be assembled, and the structure is simple. When operating, the user only needs to press on the press part 21 from top to bottom, which is convenient. The cover 2 is sealed around the edge, and forms a storage space with the hopper barrel 11 which has high sealing performance. In addition, the traditional bottle cap with storage function generally only has a tearable groove on the bottom of the hopper barrel 11. When the press part 21 is pressed down, the pressing column 22 often presses on the bottom of the hopper barrel 11, which often causes the bottom of the hopper barrel 11 to break eccentrically, with a small broken opening and a distorted broken opening, and finally causes uneven and incomplete discharge, slow discharge and other problems. Therefore, the bottle cap with storage function of the embodiment has a special slotting design. The bending grooves 12 form a polygonal structure and surround the pressure point P. When the pressure point P receives the downward thrust, the broken opening area A surrounded by the bending grooves 12 is more easily deformed, and the material outside the broken opening area A is less affected. At the same time, the tearable groove 13 extends from the end point of the polygon to the center. When the pressing column 22 is pressed down, stress concentration is first generated at the position of the tearable groove 13 close to the center, and then the tearable groove 13 is gradually torn from the center to the periphery, avoiding the problems of large resistance of the pressing column 22, inclination of the pressing column 22 and other problems caused by uneven resistance around the pressing column 22 when it is pressed down. The bottom of the hopper barrel 11 is evenly broken from the pressure point P to the periphery along the tearable groove 13, the broken opening is regular and uniform, and fast and uniform discharge is ensured.

[0028] Preferably, the bottom of the hopper 11 is provided with an arc-shaped tear groove 14 around the pressure point P, and the tearable grooves 13 are connected to the arc-shaped tear grooves 14, thereby making each tearable groove 13 interconnected. Figure 5 As shown, the arc-shaped tear groove 14 forms an area for the top pressure column 22 to press down, avoiding the top pressure column 22 from directly pressing on the tearable groove 13 or the arc-shaped tear groove 14, which would cause uneven force distribution, or the top pressure column 22 directly piercing the material and the tearable groove 13 not being completely cracked, thus ensuring the stability of the structure.

[0029] As a preferred option, such as Figure 3 As shown, the sealing member 2 is made of soft plastic or soft silicone, and the sealing member 2 includes an annular mounting plate 23 located at the edge, such as... Figure 3 and Figure 4 As shown, the pressing part 21 is connected to the inner side of the annular mounting plate 23 and has a shape that is first concave and then convex from the edge to the center. That is, the pressing part 21 is made of thin-walled material, the middle part of the pressing part 21 is an upwardly arched cylindrical shape, and the periphery of the pressing part 21 is a downwardly concave shape. This is beneficial to improving the deformability of the pressing part 21. The bottle cap 1 has an annular mounting surface 15 around the opening of the hopper 11. The annular mounting plate 23 matches the shape of the annular mounting surface 15. The annular mounting plate 23 is connected to the annular mounting surface 15 by a hot pressing process. The hot pressing process is that the annular mounting plate 23 is pressed down and heated from above, so that the annular mounting plate 23 is pressed onto the annular mounting surface 15 and the material of the annular mounting plate 23 is locally melted and bonded to the annular mounting surface 15. Of course, for ease of processing, the annular mounting plate 23 can also be connected to the annular mounting surface 15 by adhesive bonding. As a further optimized solution, such as Figure 3 and Figure 4 As shown, the bottom of the annular mounting plate 23 is provided with an annular rib 231, and the annular mounting surface 15 is provided with a receiving groove 151 for accommodating the annular rib 231. This can enhance the connection stability between the annular mounting plate 23 and the annular mounting surface 15 and improve the sealing performance. In addition, during the hot pressing process, the annular rib 231 can be partially melted and embedded into the receiving groove 151, resulting in a stable connection.

[0030] As a preferred option, such as Figures 1 to 3 As shown, the top of the bottle cap 1 is provided with an anti-accidental contact panel 16 surrounding the opening of the hopper 11. This is mainly to prevent the user from accidentally pressing down the pressing part 21 of the capping part 2, and to prevent the product from being squeezed during transportation and pressing down the pressing part 21.

[0031] Therefore, in order to facilitate normal pressing of the pressing part 21 of the sealing member 2, such as Figures 1 to 3As shown, the anti-misoperation surrounding plate 16 is provided with an operation gap 161 for the hand to stretch in for operation.

[0032] As a preferred embodiment, as shown in Figure 4 and Figure 5 As shown, the bending groove 12 forms a triangular broken hole area A, the tearable groove 13 and the arc-shaped tear groove 14 divide the broken hole area A into three broken piece partitions A1, the tearable groove 13, the arc-shaped tear groove 14 and the arc-shaped tear groove 14 are arranged on the lower surface of the bottom of the hopper barrel 11, and the bottom of the hopper barrel 11 is provided with a reinforcing protrusion 17 corresponding to each broken piece partition A1 on the upper surface, so that the material in each broken piece partition A1 is not easy to deform, and the bottom of the hopper barrel 11 is preferably torn from the tearable groove 13.

[0033] As shown in Figure 3 The cross section of the tearable groove 13 and the arc-shaped tear groove 14 is an isosceles trapezoid or an isosceles triangle which gradually narrows from bottom to top.

[0034] In order to ensure that the material at the bending groove 12 will only bend and not break, as shown in Figure 2 and Figure 3 The cross section of the bending groove 12 is a trapezoid, and the slope of the waist line close to the pressure point P is smaller than the slope of the waist line away from the pressure point P, as shown in Figure 3 The side waist line 121 close to the pressure point P and the side waist line 122 away from the pressure point P of the cross section of the bending groove 12, it can be seen that the slope of the waist line 121 is more gentle, so that when the tearable groove 13 is torn, the material in each broken piece partition A1 can be deformed and bent at the bending groove 12.

[0035] Example two

[0036] The utility model provides a simple structure's can store material formula bottle lid with the difference of example one, as shown in Figure 6 The bending groove 12 in the embodiment is provided with 6 strips, and the tearable groove 13 is also provided with 6 strips, and one end of the tearable groove 13 is communicated with the end point of the bending groove 12.

[0037] The above-mentioned is only the embodiment of the utility model, and the specific structure and the characteristics of the scheme known in the art are not described too much here. It should be pointed out that for those skilled in the art, without departing from the structure of the utility model, a number of deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect and the practicability of the utility model.
