Description

[0001] This application is a divisional application of Chinese patent application CN201810851742.3, filed on July 30, 2018, entitled “A reservoir-type bottle cap with anti-misoperation function”. Technical Field

[0002] The invention relates to the technical field of packaging and storage, in particular to a storage-type bottle cap with the function of preventing misoperation. Background Art

[0003] Many products currently on the market come in the form of solvents and require mixing with a liquid before use. These products include mixed beverages, foods, pharmaceuticals, cosmetics, milk powder formulas, nutritional supplements, supplements, and mixed adhesives. These mixed products often lack the ability to maintain their activity, stability, usability, or strength for extended periods of time. Separating these products from the packaging can prevent them from being stored for extended periods. This creates a need for a user-friendly packaging and storage device that not only allows for separate packaging but also provides ease of portability and simple operation. Reservoir bottles with simple mixing operations and convenient carrying and transportation are favored by many manufacturers as carriers for packaging and storing the above-mentioned products. Reservoir bottles are usually sealed with reservoir-type bottle caps, but existing reservoir-type bottle caps have the following defects: poor sealing, which causes the substances in the reservoir bottle to clump due to moisture; the assembly process between components is complicated, which increases costs; the overall structural design is complicated and difficult for users to use; for example: a. The resistance during pressing is too large, making it difficult to use and operate; b. When using, it is necessary to unscrew the bottle cap, then open the reservoir bottle cap, and pour the substance in the bottle cap into the bottle. This process is complicated to operate, and the substance in the bottle cap is easy to leak out during the pouring process, and ultimately the predetermined ratio result cannot be achieved; c. The operation is unstable. Summary of the Invention

[0004] The reservoir-type bottle cap with anti-misoperation function provided by the present invention solves one or more of the above-mentioned technical problems.

[0005] A reservoir-type bottle cap with anti-misoperation function, comprising: an upper cover body 1, a lower cover body 2, and a sealing sheet 3; the sealing sheet 3 is hot-melt fixed in a sealing sheet accommodating recess 11 at the upper end of the upper cover body 1, or the sealing sheet 3 and the upper end of the upper cover body 1 are an integrally formed sealing structure, and the upper cover body 1 and the lower cover body 2 are threadedly connected; a storage cavity for storing a formula substance (the formula substance can be powder, solid, or liquid) is surrounded by the upper cover body 1, the lower cover body 2, and the sealing sheet 3, and the upper cover body comprises an outer upper cover cylindrical outer cover 12 and an inner annular puncture structure 16 connected by a planar connecting bridge 13, wherein the sealing sheet accommodating recess 11 is located on the inner side of the connecting bridge 13, the lower end surface of the upper cover cylindrical outer cover 12 is connected to a tear C ring 15 via a small connecting column 14, and the inner side of the upper cover cylindrical outer cover 12 is processed with an upper cover internal thread 121 The lower end edge of the annular puncture structure 16 is provided with a puncture tooth 161; the lower cover body 2 includes an inner connecting ring 21, an outer lower cover cylindrical outer cover 22, and a spacer 23 sealed and fixed at the lower end of the connecting ring 21. The outer side of the upper end of the connecting ring 21 is processed with a lower cover external thread 211, the inner side of the lower end is sealed and fixed with a spacer 23, and the inner side of the lower cover cylindrical outer cover 22 is processed with a lower cover internal thread 221; the upper part of the connecting ring 21 in the lower cover body 2 is inserted into the upper cover body 1 and the position between the inner side of the upper cover cylindrical outer cover 12 and the annular puncturing structure 16 and the threaded engagement of the upper cover internal thread 121 and the lower cover external thread 211 realizes the connection between the upper cover body 1 and the lower cover body 2, and at the same time realizes the sealing of the storage cavity for storing the formula material; when the upper cover body 1 and the lower cover body 2 are assembled, the tearing C ring 15 is located above the upper end surface of the lower cover cylindrical outer cover 22 (the tearing C ring 15 can be in contact with or not in contact with the lower cover cylindrical outer cover 22), and the lower end of the puncturing tooth 161 in the annular puncturing structure 16 is directly opposite to the edge position of the isolation sheet 23 and the vertical distance between the lower end of the puncturing tooth 161 and the edge of the isolation sheet 23 is greater than or equal to the vertical distance between the lower end surface of the tearing C ring 15 and the upper end surface of the lower cover cylindrical outer cover 22 to avoid the tearing C ring 15 not being separated from the upper cover cylindrical outer cover 12 during storage and transportation, and accidentally causing the formula material in the storage cavity to leak. When the first anti-loosening structure fails (for example, after the tear C ring is torn off), the second anti-loosening structure starts to work, preventing the upper cover from being twisted upside down and separated from the lower cover, causing leakage of the formula in the storage cavity.

[0006] The hot-melt fixing structure or the one-piece molding structure of the sealing sheet 3 and the sealing sheet accommodating recess 11 in the upper cover body 1 corresponds to different methods of adding formula substances and the assembly methods of the upper cover body 1 and the lower cover body 2. For the hot-melt fixing structure: first complete the forward assembly of the upper cover body 1 and the lower cover body 2, add the formula substance to the storage cavity, and then fix the sealing sheet 3 with hot melt in the sealing sheet accommodating recess 11 of the upper cover body 1 to seal the formula substance in the storage cavity; for the one-piece molding structure of the sealing sheet 3 and the upper end of the upper cover body 1: first invert the upper cover body 1, and add the formula substance to the storage cavity surrounded by the inner wall of the annular puncture structure 16 of the upper cover body 1 and the sealing sheet 3. Similarly, invert the lower cover body 2 and threadedly connect it with the inverted upper cover body 1 to seal the formula substance in the storage cavity. The internal thread 221 of the lower cover 2 is connected with the external thread of the upper port of the bottle body to complete the threaded fixation of the reservoir-type bottle cap and the bottle body, thereby separating the formula material contained in the bottle body from the formula material stored in the storage cavity of the reservoir-type bottle cap. When the two formula materials need to be mixed, the operator needs to pull the tear C ring 15 first. As the connecting column 14 breaks, the tear C ring 15 is separated from the lower end surface of the upper cover cylindrical outer cover 12 and reserves the downward space of the upper cover body 1. In the process of the operator twisting the upper cover body 1 to bring it close to the lower cover body 2, the lower end of the puncture tooth 161 contacts and punctures the thinner edge position of the isolation sheet 23, causing the formula material to leak and be released into the bottle body for mixing.

[0007] The above-mentioned reservoir-type bottle cap has a simple structure and assembly process (only the upper cover body 1 and the lower cover body 2 need to be twisted and rotated), has low production cost and is easy for operators to use. The connection and sealing method between the sealing piece 3 and the upper cover body 1 meets the different process requirements of adding formula substances by different manufacturers. Through the action of the piercing teeth 161 on the isolation piece 23, the formula substance in the bottle cap storage cavity is completely introduced into the inner cavity of the bottle body to avoid accidental leakage.

[0008] Preferably, the reservoir-type bottle cap with anti-misoperation function has a sealing assembly provided in the upper cover body 1 and the lower cover body 2, wherein the sealing assembly includes an upper cover sealing ring 17 located between the outer upper cover cylindrical outer cover 12 and the inner circular annular puncture structure 16 in the upper cover body 1, and the upper end of the upper cover sealing ring 17 is integrally formed with the upper cover body 1, and the sealing assembly also includes a lower cover sealing ring 212 located at the upper end of the connecting ring 21 in the lower cover body 2. The upper cover sealing ring 17 and the lower cover sealing ring 212 are assembled by interference fit, which further improves the sealing of the storage cavity, prevents air from entering the storage cavity and causing oxidation and deterioration of the formula material, and prevents moisture from entering the storage cavity and causing the formula material to become damp and reduce its performance.

[0009] Preferably, in the reservoir-type bottle cap with anti-misoperation function, the inner side of the end surface of the lower cover cylindrical outer cover 22 in the lower cover body 2 is processed with an integrated sealing ring 24 extending downward, and the integrated sealing ring 24 is located between the lower cover inner thread 221 and the connecting ring 21. The outer side surface of the integrated sealing ring 24 is an arc surface that matches the inner side surface of the bottle body and the bottle mouth. When the reservoir-type bottle cap is assembled with the bottle body thread, the outer side surface of the integrated sealing ring 24 is tightly against the inner side surface of the bottle body and the bottle mouth and has an interference fit with the inner side surface of the bottle mouth.

[0010] By providing the integrated sealing ring 24 in the lower cover 2, the sealing between the reservoir cover and the bottle body is further improved, thereby preventing leakage of the formula in the bottle body due to severe shaking during storage and transportation.

[0011] Preferably, in the reservoir-type bottle cap with anti-misoperation function, a downwardly extending side sealing ring 25 is processed on the inner side of the end surface of the cylindrical outer cover 22 of the lower cover in the lower cover body 2, and the side sealing ring 25 is located between the integrated sealing ring 24 and the inner thread 221 of the lower cover. The side sealing ring 25 is processed with an arc surface matching the outer side surface of the bottle body and the bottle mouth close to the integrated sealing ring 24, and the volume space between the side sealing ring 25 and the integrated sealing ring 24 just matches the shape and size of the upper edge of the bottle mouth and allows the placement of the upper edge of the bottle mouth of the bottle body. The bottle mouth of the bottle body is stuck between the side sealing ring 25 and the integrated sealing ring 24, and the side sealing ring 25 is interference fit with the outer side surface of the bottle body and the bottle mouth.

[0012] The bottle mouth is clamped and sealed between the side sealing ring 25 and the integral sealing ring 24. The sealing structure on both sides of the bottle mouth further improves the sealing between the bottle cap and the bottle body, further ensuring the storage safety of the formula in the bottle body.

[0013] Preferably, in the reservoir-type bottle cap with anti-misoperation function, a tear C-ring 26 is fixed to the lower end surface of the lower cylindrical outer cover 22 in the lower cover body 2 via a small connecting column. The inner side surface of the tear C-ring 26 is processed with anti-slip protrusions 261 arranged in a circumferential direction. Correspondingly, the outer side surface of the bottle body is processed with grooves for use with the anti-slip protrusions 261, and the anti-slip protrusions 261 are snapped into the grooves on the outer side of the bottle body. When the reservoir bottle is not in use, the anti-slip protrusions 261 can prevent relative rotation between the reservoir-type bottle cap and the bottle body. Secondly, before use, it is necessary to pull the tear C-ring 26 to separate it from the lower cylindrical outer cover 22. Therefore, the provision of the tear C-ring 26 can mark used and unused reservoir bottles.

[0014] Preferably, the reservoir-type bottle cap with anti-misoperation function is provided with at least one set of first anti-loosening structure in the upper cover body 1 and the lower cover body 2. The first anti-loosening structure includes a plurality of first anti-loosening hooks 151 arranged along the circumferential direction at the lower end of the inner side surface of the tear C ring 15 in the upper cover body 1, wherein the first inclined plane 1511 of a single first anti-loosening hook 151 has a small inclination angle (the angle between the first inclined plane 1511 and the tangent line of the circle in which it is located) and a long length, and the inclination angle of the second inclined plane 1512 (the angle between the second inclined plane 1512 and the tangent line of the circle in which it is located) is large. The angle between the inclined surface 1512 and the tangent of the circle in which it is located is large and the length is small. The first anti-loosening structure also includes a second anti-loosening hook 213 integrally formed with the outer side of the connecting ring 21 in the lower cover body 2. During the rotational assembly of the upper cover body 1 and the lower cover body 2, the second anti-loosening hook 213 passes through the first inclined plane 1511 and then the second inclined surface 1512 relative to the single first anti-loosening hook 151, and then is snap-connected with the end face of the second inclined surface 1512 of the first anti-loosening hook 151.

[0015] Through the interference and snapping effect between the first anti-loosening hook 151 and the second anti-loosening hook 213, the upper cover body 1 and the lower cover body 2 that are threadedly connected are prevented from reversing and causing the connection to loosen before use. The setting of the first inclined surface 1511 and the second inclined surface 1512 in the first anti-loosening hook 151 makes it easy to rotate the second anti-loosening hook 213 and the first anti-loosening hook 151 while optimizing the snapping function of the anti-loosening structure.

[0016] Preferably, in the reservoir-type bottle cap with anti-misoperation function, the angle α between the first inclined plane 1511 and the tangent line of the circle at the first anti-loosening hook 151 is 5° to 45°, and the angle β between the second inclined plane 1512 and the tangent line of the circle at the first anti-loosening hook 151 is 50° to 80°.

[0017] Preferably, in the reservoir-type bottle cap with anti-misoperation function, the first anti-loosening hook 151 in the tear C ring 15 in the anti-loosening structure and the buckle valley 1513 between two adjacent first anti-loosening hooks 151 are arranged continuously end to end in the circumferential direction, and the second anti-loosening hooks 213 on the outside of the connecting ring 21 are arranged at intervals along the circumferential direction of the connecting ring 21, and the buckle tip 2131 of the second anti-loosening hook 213 can be tightly buckled in the buckle valley 1513 between two adjacent first anti-loosening hooks 151. Preferably, 2 to 5 second anti-loosening hooks 213 are arranged at equal intervals on the outside of the connecting ring 21.

[0018] The first anti-loosening hook 151 and the buckle valley 1513 are arranged continuously end to end along the circumferential direction, and the buckle tip 2131 of the second anti-loosening hook 213 can be tightly buckled in the buckle valley 1513 between two adjacent first anti-loosening hooks 151, which can ensure the anti-loosening precision of the anti-loosening structure and strictly suppress the reverse loosening phenomenon between the upper cover body 1 and the lower cover body 2. The second anti-loosening hook 213 is spaced apart along the circumferential direction mainly to avoid the phenomenon of increased output force when the upper cover body 1 and the lower cover body 2 are threadedly connected due to the setting of the anti-loosening structure, thereby ensuring anti-loosening without increasing the labor intensity of the operator.

[0019] Preferably, the reservoir-type bottle cap with anti-misoperation function has a second anti-loosening structure between the upper cover body 1 and the lower cover body 2, and the second anti-loosening structure includes a first threaded boss 1211 and a second threaded boss 215; the first threaded boss 1211 is arranged in the valley between the adjacent upper and lower thread circles in the upper cover internal thread 121, and N first threaded bosses 1211 are arranged along the circumferential direction; the lower cover external thread 211 is N segmented threads arranged in a spiral, that is, the lower cover external thread 211 is composed of N segmented threads, and the end of each segmented thread of the lower cover external thread 211 includes a second threaded boss 215 (the lower cover external thread 211 includes N Second thread bosses 215), where N is any natural number from 1 to 4. During the process of threaded connection between the upper cover body 1 and the lower cover body 2, the segmented lower cover external thread 211 avoids the first thread boss 1211 when it is twisted and spirally ascended in the upper cover internal thread 121 (that is, the first thread boss 1211 just passes through the gap between adjacent segmented threads). At the end point of the spiral ascent, the first thread boss 1211 is located in front of the spiral of the second thread boss 215, thereby avoiding human error in storage and transportation before use or bumps and vibrations that cause the upper cover body 1 and the lower cover body 2 to rotate in the opposite direction, thereby preventing leakage of the formula substance in the storage cavity.

[0020] Preferably, the reservoir-type bottle cap with anti-misoperation function has a third anti-loosening structure between the upper cover body 1 and the lower cover body 2, and the third anti-loosening structure includes M first positioning ribs 162 and M second positioning ribs 214; the long first positioning ribs 162 are located on the outer side of the annular puncture structure 16 and extend along the central axis of the annular puncture structure 16 and are arranged at equal angles in the circumferential direction; the second positioning ribs 214 are located on the inner side of the connecting ring 21 and the M second positioning ribs 214 are arranged at equal angles in the circumferential direction. After the C ring 15 is torn off the upper cover cylindrical outer cover 12, the upper cover body 1 moves toward the lower cover body 2 and causes the puncture teeth 161 to puncture the isolation sheet 23 During the positioning process, the first positioning rib 162 and the second positioning rib 214 approach each other in a spiral trajectory in the vertical direction. After the piercing tooth 161 pierces the isolation sheet 23, the M first positioning ribs 162 and the M second positioning ribs 214 are in a state of mutual conflict. The starting point of contact between a single first positioning rib 162 and a single second positioning rib 214 is that the first arc surface 1621 in the first positioning rib 162 first passes over the second arc surface 2141 in the second positioning rib 214, and the end point of contact is that the first straight end surface 1622 in the first positioning rib 162 is snap-connected with the second straight end surface 2142 of the second positioning rib 214, and M is a natural number from 2 to 5.

[0021] After the tear C ring 15 in the upper cover body 1 is detached, the upper cover body 1 is moved toward the lower cover body 2 by spiral twisting. After the puncturing tooth 161 punctures the isolation sheet 23, the first positioning rib 162 and the second positioning rib 214 are close to each other in a spiral trajectory and finally the straight end faces of the two positioning ribs are snapped together. When the user needs to separate the entire reservoir-type bottle cap from the bottle body, whether twisting the upper cover body 1 or the lower cover body 2 can achieve the purpose of separating the bottle cap from the bottle body. The snap action before the third anti-loosening structure will prevent the upper cover body 1 and the lower cover body 2 from being relatively separated due to the reversing operation, avoiding the user's secondary operation and ensuring that the separation operation of the bottle cap and the bottle body is completed in one go.

[0022] Preferably, in the reservoir-type bottle cap with anti-misoperation function, the specific shape of the puncturing teeth 161 at the lower end of the annular puncturing structure 16 is one of saw-like teeth, dense small teeth, knife-shaped teeth or knife-shaped teeth plus guide posts, wherein in the puncturing teeth 161 with knife-shaped teeth plus guide posts, the guide posts are located at the center of the annular puncturing structure 16.

[0023] Preferably, in the reservoir-type bottle cap with anti-misoperation function, the ratio of the serrated teeth, dense small teeth, and knife-shaped teeth in the puncture teeth 161 to the circumference of the lower end of the annular puncture structure 16 is greater than or equal to 0.25 and less than or equal to 0.5, or greater than 0.5 and less than 1.

[0024] According to multiple puncture experiments, when the ratio is between 0.25 and 0.5: the puncture force of the saw-shaped teeth is moderate, and the isolation plate 23 is partially separated from the lower cover body 2 after puncture; the puncture force of the dense small teeth is relatively large, and the isolation plate 23 may be completely separated or partially separated from the lower cover body 2 after puncture; the puncture force of the knife-shaped teeth is relatively large, and the isolation plate 23 is partially separated from the lower cover body 2 after puncture; the puncture force of the knife-shaped teeth plus the guide post is relatively large, and the isolation plate 23 is partially separated from the lower cover body 2 after puncture. When the ratio is between 0.5 and 1, the puncture force of the saw-shaped teeth is moderate, and the isolation plate 23 is completely separated from the lower cover body 2 after puncture; the puncture force of the dense small teeth is relatively large, and the isolation plate 23 is completely separated from the lower cover body 2 after puncture; the puncture force of the knife-shaped teeth is relatively large, and the isolation plate 23 is completely separated from the lower cover body 2 after puncture; the puncture force of the knife-shaped teeth plus the guide post is relatively large, and the isolation plate 23 is completely separated from the lower cover body 2 after puncture. During the specific design, reasonable selection can be made based on customer requirements while ensuring that the puncture teeth are simple to process, and trying to meet the customer's requirements on the puncture force and whether the isolation sheet 23 is allowed to be completely separated from the lower cover body 2.

[0042] Among them, a sealing component is provided in the upper cover body 1 and the lower cover body 2, wherein the sealing component includes an upper cover sealing ring 17 located between the outer upper cover cylindrical outer cover 12 and the inner annular puncture structure 16 in the upper cover body 1, and the upper end of the upper cover sealing ring 17 is integrally formed with the upper cover body 1, and the sealing component also includes a lower cover sealing ring 212 located at the upper end of the connecting ring 21 in the lower cover body 2.

[0077] Furthermore, a third anti-loosening structure is provided between the upper cover body 1 and the lower cover body 2, and the third anti-loosening structure includes four first positioning ribs 162 and four second positioning ribs 214; the long first positioning rib 162 is located on the outer side of the annular puncture structure 16 and extends along the central axis direction of the annular puncture structure 16 and is arranged at equal angles in the circumferential direction; the second positioning rib 214 is located on the inner side of the connecting ring 21 and the four second positioning ribs 214 are arranged at equal angles in the circumferential direction. After the tearing C ring 15 is separated from the upper cover cylindrical outer cover 12, the upper cover body 1 moves toward the lower cover body 2 and causes the puncture teeth 161 to puncture the isolation sheet 23. During the process, the first positioning rib 162 and the second positioning rib 214 approach each other in a spiral trajectory in the vertical direction. After the piercing tooth 161 pierces the isolation plate 23, the four first positioning ribs 162 and the four second positioning ribs 214 are in a state of mutual conflict. The starting point of contact between a single first positioning rib 162 and a single second positioning rib 214 is that the first arc surface 1621 in the first positioning rib 162 first passes over the second arc surface 2141 in the second positioning rib 214, and the end point of contact is that the first straight end surface 1622 in the first positioning rib 162 is snap-connected with the second straight end surface 2142 of the second positioning rib 214.

[0078] The assembly structure and assembly process between the upper cover body 1 and the lower cover body 2 in the reservoir-type bottle cap for preventing misoperation involved in this specific implementation case are simple, cost-effective and easy for users to operate. The assembly method of the upper cover body 1 and the sealing plate 3 meets the different needs of customers for the addition method of the formula material in the storage cavity and will not cause accidental leakage during the mixing process of the formula material; the setting of the sealing component ensures the sealing of the storage cavity, and prevents the infiltration of objects such as air, water, and impurities that lead to the failure of the formula material; the setting of the first anti-loosening structure and the second anti-loosening structure in the upper cover body 1 and the lower cover body 2 prevents the reservoir bottle from rotating in the reverse direction and destroying the sealing of the storage cavity due to human error operation or bumps and vibrations during storage and transportation before use; the setting of the third anti-loosening structure in the upper cover body 1 and the lower cover body 2 ensures that after the reservoir bottle is used, the upper cover body 1 and the lower cover body 2 will not reverse and separate, and ensures that the user can complete the separation of the entire cover body from the bottle body at one time regardless of whether the upper cover body 1 or the lower cover body 2 is twisted.
