Description

A rotating mixing device Technical Field

[0001] The invention relates to the technical field of daily chemical products and food packaging containers, in particular to a rotary-opening mixing device. Background Art

[0002] In the technical field of daily chemical product or food packaging, there is a large demand for solid-liquid mixing or liquid-liquid mixing. The solid-liquid mixing or liquid-liquid mixing packaging in the existing technology usually stores a first material in the cover body and a second material in the bottle body. The cover body is provided with a puncture member and a puncturable sealing film or sealing member. By pressing the cover body downward, the puncture member punctures the sealing film or sealing member to release the first material.

[0003] The defects of this type of packaging device are: first, the safety ring needs to be torn off before use, and after being torn off, the safety ring is easy to fall into the environment and pollute the environment and is difficult to recycle; second, the same action is used during factory assembly and when opened for the first time on the user's end. For example, the cover and bottle body are assembled by pressing down during assembly, and the user also presses down on the cover body to puncture it when using it. At this time, the error rate of the assembly line is relatively high. The reason is that in order to facilitate the user to start the mixing device, it is difficult to set a strong limit structure to prompt that it has been assembled to the predetermined position. During assembly, the puncture part can easily puncture the sealing film or seal, causing the device to fail; third, when in use, it is necessary to squeeze the bottle body or pour the bottle mouth to mix the mixed liquid, and it is difficult to control the amount of mixing.

[0041] As shown in FIG. 1 and FIG. 2 , this embodiment provides a rotating-opening mixing device, comprising a bottle body 1 , a first cover body 2 , a second cover body 3 and a massage head 4 .

[0042] As shown in Figures 2 and 5, a first opening 11 is provided at the first end of the bottle body 1. The first cover body 2 includes an upper cover body 21 and a lower cover body 22. The lower cover body 22 is connected to the first end of the bottle body 1 and covers the first opening 11. The upper cover body 21 is connected to the outer periphery of the lower cover body 22 by a threaded structure, and can also be connected to the outer periphery of the lower cover body 22 by an assembly structure well known to those skilled in the art, such as a guide rail structure or a guide groove structure. A septum 221 is provided in the lower cover body 22. The space formed by the septum 221, the inner wall of the upper cover body 21, and the inner wall of the lower cover body 22 constitutes a first cavity 23. The first cavity 23 is used to store the first material. A second cavity 24 is provided in the bottle body 1. The second cavity 24 is used to store the second material.

[0043] As shown in Figures 3, 5, and 6, a piercing member 211 is disposed within the upper cover 21. The piercing member 211 is connected to the inner top surface of the upper cover 21 and positioned within the first cavity 23. The piercing member 211 comprises a sheath 2111 extending downward from the inner top surface of the upper cover 21, and a sharp puncturing portion 2112 disposed at the lower end of the sheath 2111. The outer peripheral wall of the sheath 2111 is provided with an outwardly protruding first interference edge 2113, which interferes with the inner peripheral wall of the lower cover 22 to form a seal. The bottom of the puncturing portion 2112 is configured as an inclined surface. The septum 221 within the lower cover 22 is provided with a thin-walled region for easy puncture, which is arranged along the predetermined cutting path of the piercing member 211. As shown in Figures 4, 5, and 6, a breakable safety ring 212 is provided below the upper cover 21. The safety ring 212 is connected to the lower cover 22 via a breakable portion 213. The breakable portion 213 is weaker than the safety ring 212, and the breakable portion 212 is configured as a thin ring or a plurality of break bridges. A storage platform 13 is provided below the safety ring 212. The storage platform 13 is located on the outer wall of the bottle body 1 and protrudes along the outer wall of the bottle body 1 in a direction away from the axis of the bottle body 1.

[0044] As shown in Figures 5 and 6, in the initial state, the piercing member 211 is located above the partition 221. When the upper cover 21 rotates relative to the lower cover 22, the upper cover 21 presses the safety ring 212 downward, causing the safety ring 212 to fall onto the receiving platform 13. The upper cover 21 drives the piercing member 211 to move downward to press or pierce the partition 221, causing the first material to fall into the second material and mix.

[0045] As shown in Figures 4, 5, and 8, a dispensing head 12 is provided at the second end of the bottle body 1. The dispensing head 12 is used to dispense the liquid in the bottle body 1. The dispensing head 12 includes a liquid guide portion 121 and a liquid outlet tooth 122 connected to the liquid guide portion 121. The inner circumferential surface of the connection between the liquid guide portion 121 and the liquid outlet tooth 122 is an inclined surface. The aforementioned inclined surface is used to guide the liquid into the outlet tooth 122 to prevent the formation of material accumulation in the bottle body 1.

[0046] As shown in Figures 2 and 9, an elastic soft-glue button 214 is provided at the upper end of the upper cover 21. Ribs 2141 are provided on the inner top surface of the soft-glue button 214. Ribs 2141 are stronger than the soft-glue button 214. Ribs 2141 can be directly fixed to the soft-glue button 214, or they can be integrally injection-molded with the upper cover 21. The soft-glue button 214 is then overmolded or mounted to the upper cover 21, with the ribs 2141 in close contact with the inner top surface of the soft-glue button 214. During the pressing process, the ribs 2141 allow the soft-glue button 214 to rebound more quickly and evenly.

[0047] As shown in FIG4 , a first alignment structure 14 is provided on the outer peripheral wall of the first end portion of the bottle body 1, and a second alignment structure 222 is provided on the outer peripheral wall of the lower cover body 22. The first alignment structure 14 is a first boss, and the second alignment structure 222 is a second groove that cooperates with the first alignment structure 14. A first alignment opening is provided at the first end portion of the second groove. The first boss enters the first groove from the first alignment opening and abuts against the first groove or the second end portion. The first alignment structure 14 and the second alignment structure 222 constitute a first limiting portion. The first limiting portion is used to control the relative position and assembly height between the bottle body 1 and the lower cover body 22 during assembly.

[0048] As shown in Figure 3, a third alignment structure 223 is provided on the outer peripheral wall of the lower cover body 22, and the third alignment structure 223 is a third groove. A fourth alignment structure 215 is provided on the inner peripheral wall of the upper cover body 21, and the fourth alignment structure 215 is a fourth boss that cooperates with the third alignment structure 223. Openings are provided at the upper and lower ends of the third groove, and the fourth boss can enter or escape from the third groove from the openings, so that the third alignment structure 223 and the fourth alignment structure 215 constitute a second limiting portion.

[0049] As shown in Figures 3, 5 and 6, the second limiting portion is used to control the relative position between the upper cover body 21 and the lower cover body 22 during assembly, so as to control the threaded structure between the upper cover body 21 and the lower cover body 22 at a predetermined position. When the predetermined position is reached, the threads between the upper cover body 21 and the lower cover body 22 will interfere to control the assembly height between the upper cover body 21 and the lower cover body 22, thereby preventing the piercing member 211 from piercing the spacer 221 when inserted too deeply, resulting in assembly failure.

[0050] As shown in Figures 2, 5, and 8, the dispensing head 12 can be provided with one or more liquid outlet teeth 122. The second cover 3 can be removably attached to the dispensing head 12. A sealing member is provided within the second cover 3. This sealing member can be a sealing gasket, a sealing insert structure, a sealing protrusion, or other sealing structures known to those skilled in the art. In this embodiment, a sealing gasket 31 is provided within the second cover 3. The sealing gasket 31 can be combined with the inner top surface of the second cover 3. When the second cover 3 is attached to the dispensing head 12, the liquid outlet opening 1221 is pressed against the sealing gasket 31.

[0051] As shown in FIG. 2 and FIG. 7 , the massage head 4 includes a plurality of massage teeth 41 , and the massage head 4 is detachably combined with the matching head 12 .

[0052] The technical solution described in the above embodiment is used as follows:

[0053] As shown in the figure, during assembly, first align the second alignment structure 222 of the lower cover 21 with the first alignment structure 14 of the bottle body, and then press down the lower cover 21 so that the first alignment structure 14, i.e., the first boss, is inserted into the second alignment structure 222, i.e., the second groove, until the first boss abuts against the second end of the second groove. At this time, the lower cover 21 and the bottle body 1 are assembled; then align the fourth alignment structure 215, i.e., the fourth boss, of the upper cover 21 with the third alignment structure 223, i.e., the third groove, of the lower cover 21, and press down the upper cover 21. The fourth boss enters the third groove, thereby controlling the relative position between the upper cover body 21 and the lower cover body 22, so that the thread between the two can be controlled at a predetermined position. When the upper cover body 21 is continued to be pressed down until the fourth boss is out of the third groove, the threads between the upper cover body 21 and the lower cover body 22 reach a predetermined initial position and form interference, making it difficult for the upper cover body 21 to be further pressed down, thereby controlling the assembly height between the upper cover body 21 and the lower cover body 22, and preventing the piercing member 211 from piercing the spacer 221 when inserted too deep, resulting in assembly failure.

[0054] When the user uses it, it is opened for the first time: the upper cover body 21 is rotated. Since the fourth alignment structure 215, that is, the fourth boss, has been separated from the third alignment structure 223, that is, the third groove, the rotation of the upper cover body 21 will not be restricted by the above structure. When the upper cover body 21 is rotated, the lower end of the upper cover body 21 presses downward against the safety ring 212, and the breakable part 213 breaks. The safety ring 212 separates from the lower cover body 22 and falls on the storage platform 13. The upper cover body 21 is continued to be rotated. The upper cover body 21 drives the piercing member 211 to move downward and cut the spacer 221. The second material stored in the second cavity 24 falls into the first cavity 23 in the bottle body 1 and mixes with the first material. Shake the bottle body 1 to mix the first material and the second material evenly.

[0055] Dispensing liquid: remove the second cover 3 and press the soft rubber button 214 to generate a pressure difference in the bottle 1 , thereby dispensing the liquid from the liquid outlet 1221 of the dispensing head 12 .

[0056] Optionally, a massage head 4 can be installed on the dispensing head 12 according to user needs so that it can be used on the scalp or other places. At this time, after the liquid is dispensed from the liquid outlet 1221, it is evenly spread through the massage head 4 and massage is used to promote absorption.

It should be understood that numerous modifications and variations based on the concepts of the present invention can be made by those skilled in the art without inventive effort. Therefore, any technical solution that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
