Description

[0001] The present application is a divisional application of Chinese Patent Application No. CN201810851742.3, filed on July 30, 2018, entitled "A Storage Type Bottle Cap with Anti-misoperation". TECHNICAL FIELD

[0002] The present application relates to the technical field of packaging and storage, in particular to a storage type bottle cap with anti-misoperation. BACKGROUND

[0003] Many products on the market are in the form of solvents, which need to be mixed with a certain liquid before use. These products involve: mixed beverages, food, medicine, cosmetics, milk powder formula, nutritional products, supplements, mixed use of glue, etc. The products used after mixing cannot maintain long-term activity, stability, effective use, strength after mixing. If isolated alone, it can be stored for a long time. This requires a packaging and storage device that can achieve separate packaging and is convenient for users to carry and easy to operate during use. The storage bottle, as a carrier for packaging and storing the above products, is favored by many manufacturers. The storage bottle is usually sealed with a storage type bottle cap, but the existing storage type bottle cap has the following defects: poor sealing, leading to clumping of the material in the storage bottle due to moisture; complex assembly process between parts, leading to increased cost; complex overall structure design, difficult for users to use; for example: a. The resistance is too large when pressing, making it difficult to operate; b. When using, the bottle cap needs to be unscrewed, then the storage bottle cap is opened, and the material in the bottle cap is poured into the bottle. This process is complex, and the material in the bottle cap is easy to leak during pouring, ultimately failing to achieve the desired mixing ratio; c. Unstable operation. SUMMARY

[0004] The storage type bottle cap with anti-misoperation of the present application solves one or more of the above technical problems.

[0005] The application discloses a misoperation-proof storage type bottle cap, which comprises an upper cap body 1, a lower cap body 2 and a sealing sheet 3, the sealing sheet 3 is fixed in a sealing sheet accommodating concave 11 at the upper end of the upper cap body 1 by hot melting or is integrally formed with the upper end of the upper cap body 1, and the upper cap body 1 is threadedly connected with the lower cap body 2; a storage cavity for storing formula substances (the formula substances can be powder, solid or liquid) is formed among the upper cap body 1, the lower cap body 2 and the sealing sheet 3, the upper cap body comprises an outer layer upper cap cylindrical cover 12 and an inner layer circular ring-shaped piercing structure 16 which are connected through a plane connecting bridge 13, the sealing sheet accommodating concave 11 is located at the inner side of the connecting bridge 13, a tear C ring 15 is connected to the lower end surface of the upper cap cylindrical cover 12 through a small connecting column 14, the inner side of the upper cap cylindrical cover 12 is processed with an upper cap inner thread 121, and the lower end edge of the circular ring-shaped piercing structure 16 is provided with piercing teeth 161; the lower cap body 2 comprises an inner side connecting ring 21, an outer side lower cap cylindrical cover 22 and an isolation sheet 23 which is sealingly 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 cap outer thread 211, the inner side of the lower end of the connecting ring 21 is sealingly fixed with the isolation sheet 23, and the inner side of the lower cap cylindrical cover 22 is processed with a lower cap inner thread 221; the upper part of the connecting ring 21 in the lower cap body 2 is inserted into the position between the inner side of the upper cap cylindrical cover 12 and the circular ring-shaped piercing structure 16 in the upper cap body 1 and is connected with the upper cap body 1 and the lower cap body 2 through the thread engagement of the upper cap inner thread 121 and the lower cap outer thread 211, and the storage cavity for storing formula substances is sealed; in the state that the upper cap body 1 and the lower cap body 2 are assembled, the tear C ring 15 is located above the upper end surface of the lower cap cylindrical cover 22 (the tear C ring 15 can be in contact with or not in contact with the lower cap cylindrical cover 22), the lower end of the piercing teeth 161 in the circular ring-shaped piercing structure 16 is opposite to the edge position of the isolation sheet 23, and the vertical distance between the lower end of the piercing teeth 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 tear C ring 15 and the upper end surface of the lower cap cylindrical cover 22, so that the piercing teeth 161 do not pierce the edge of the isolation sheet 23 in the state that the tear C ring 15 is not separated from the upper cap cylindrical cover 12 during storage and transportation, and the formula substances in the storage cavity are prevented from being leaked; when the first anti-loosening structure is invalid (for example, the tear C ring is torn off), the second anti-loosening structure starts to work, and the upper cap is prevented from being loosened and separated from the lower cap to cause the leakage of the formula substances in the storage cavity.

[0006] The sealing sheet 3 corresponds to the hot melt fixing structure or the one-piece structure of the sealing sheet accommodating recess 11 in the upper cover body 1 respectively in different formula substance adding ways and the assembling ways of the upper cover body 1 and the lower cover body 2. For the hot melt fixing structure, the upper cover body 1 and the lower cover body 2 are assembled in the normal direction first, then the formula substance is added into the storage cavity, and then the sealing sheet 3 is fixed in the sealing sheet accommodating recess 11 in the upper cover body 1 to seal the formula substance in the storage cavity. For the one-piece structure of the sealing sheet 3 and the upper end of the upper cover body 1, the upper cover body 1 is inverted first, then the formula substance is added into the storage cavity surrounded by the inner wall of the circular ring-shaped piercing structure 16 and the sealing sheet 3, and then the lower cover body 2 is screwed with the inverted upper cover body 1 to seal the formula substance in the storage cavity. The lower cover inner thread 221 in the lower cover body 2 is connected with the outer thread of the upper end of the bottle body to complete the thread fixing of the storage type bottle cap and the bottle body, and then the formula substance in the bottle body is separated from the formula substance stored in the storage cavity of the storage type bottle cap. When the two formula substances need to be mixed, the operator needs to pull the tear C ring 15 first, and then the tear C ring 15 is separated from the lower end surface of the upper cover cylindrical outer cover 12 with the breakage of the connecting column 14 to reserve the downward space of the upper cover body 1. During the process of the operator twisting the upper cover body 1 to make it close to the lower cover body 2, the lower end of the piercing tooth 161 contacts and pierces the thinner edge position of the isolation sheet 23 to make the formula substance leak and release into the bottle body for mixing.

[0007] The above-mentioned storage type bottle cap structure has simple assembling process (only the twisting and rotating between the upper cover body 1 and the lower cover body 2 are needed), low production cost and is convenient for operators to use. The connection and sealing way of the sealing sheet 3 and the upper cover body 1 meets the different process requirements of different manufacturers in adding formula substances. The formula substance in the storage cavity of the bottle cap completely enters the inner cavity of the bottle body through the action of the piercing tooth 161 on the isolation sheet 23 to avoid accidental leakage.

[0008] Preferably, the storage type bottle cap with anti-misoperation function is provided with a sealing assembly in the upper cover body 1 and the lower cover body 2. The sealing assembly includes the upper cover sealing ring 17 between the outer layer upper cover cylindrical outer cover 12 and the inner layer circular ring-shaped piercing structure 16 in the upper cover body 1, and the upper end of the upper cover sealing ring 17 is one-piece with the upper cover body 1. The sealing assembly further includes the lower cover sealing ring 212 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 in interference fit to further improve the sealing property of the storage cavity, avoid air entering the storage cavity to oxidize and deteriorate the formula substance, and avoid moisture entering the storage cavity to make the formula substance damp and reduce the use performance.

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

[0010] Through the arrangement of the integral sealing ring 24 in the lower cover body 2, the sealing between the reservoir type cap body and the bottle body is further improved, and leakage of the formula substance in the bottle body due to violent shaking during storage and transportation is avoided.

[0011] Preferably, the anti-misoperation reservoir type bottle cap, the inner side of the end face of the lower cover cylindrical cover 22 in the lower cover body 2 is processed with an integral sealing ring 24 extending downward and located between the lower cover inner thread 221 and the connecting ring 21, the outer side of the integral sealing ring 24 is an arc surface matching the inner side of the bottle mouth, and in the assembled state of the reservoir type bottle cap and the bottle body, the outer side of the integral sealing ring 24 tightly abuts against the inner side of the bottle mouth and is in interference fit with the inner side of the bottle mouth.

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

[0013] Preferably, the anti-misoperation reservoir type bottle cap, the lower end face of the lower cover cylindrical cover 22 in the lower cover body 2 is fixed with a tear C ring 26 through a small connecting column, the inner side of the tear C ring 26 is processed with anti-skid protrusions 261 arranged in the circumferential direction, and correspondingly, the outer side of the bottle body is processed with grooves matched with the anti-skid protrusions 261, and the anti-skid protrusions 261 are clamped into the grooves on the outer side of the bottle body. When the reservoir bottle is not used, the anti-skid protrusions 261 can prevent relative rotation between the reservoir type bottle cap and the bottle body, and secondly, before use, the tear C ring 26 needs to be pulled to be separated from the lower cover cylindrical cover 22, so that the tear C ring 26 can mark the used and unused reservoir bottles.

[0014] Preferably, the anti-misoperation reservoir type bottle cap is provided with at least one set of first anti-loosening structure in the upper cap body 1 and the lower cap body 2, the first anti-loosening structure comprises a plurality of first anti-loosening hooks 151 arranged in the circumferential direction at the lower end of the inner side of the tear C ring 15 in the upper cap body 1, wherein the first inclined plane 1511 of a single first anti-loosening hook 151 has a smaller inclination angle (the included angle between the first inclined plane 1511 and the tangent line at the position) and a longer length, and the second inclined plane 1512 has a larger inclination angle (the included angle between the second inclined plane 1512 and the tangent line at the position) and a shorter length, and the first anti-loosening structure further comprises a second anti-loosening hook 213 integrally formed with the outer side of the connecting ring 21 in the lower cap body 2, during the rotating assembly of the upper cap body 1 and the lower cap body 2, the second anti-loosening hook 213 passes through the first inclined plane 1511 and then the second inclined plane 1512 relative to the single first anti-loosening hook 151, and finally buckles with the end surface of the second inclined plane 1512 of the first anti-loosening hook 151.

[0015] Through the interference buckling action between the first anti-loosening hook 151 and the second anti-loosening hook 213, before use, the reverse rotation between the thread-connected upper cap body 1 and the lower cap body 2 is avoided to cause loosening, wherein the arrangement of the first inclined plane 1511 and the second inclined plane 1512 in the first anti-loosening hook 151 enables the second anti-loosening hook 213 to rotate and buckle with the first anti-loosening hook 151, and optimizes the buckling function of the anti-loosening structure.

[0016] Preferably, in the first anti-loosening hook 151, the included angle α between the first inclined plane 1511 and the tangent line at the position is 5°-45°, and the included angle β between the second inclined plane 1512 and the tangent line at the position is 50°-80°.

[0017] Preferably, in the anti-loosening structure, the buckling valleys 1513 between the first anti-loosening hook 151 and two adjacent first anti-loosening hooks 151 in the tear C ring 15 are arranged in the circumferential direction in a continuous manner, the second anti-loosening hooks 213 on the outer side of the connecting ring 21 are arranged in the circumferential direction of the connecting ring 21 in a spaced manner, and the buckling sharp parts 2131 of the second anti-loosening hooks 213 can be buckled in the buckling valleys 1513 between two adjacent first anti-loosening hooks 151 in a close manner, and preferably, 2-5 second anti-loosening hooks 213 are arranged at equal intervals on the outer side of the connecting ring 21.

[0018] The first anti-loosening hooks 151 and the buckle valleys 1513 are arranged in a circumferential direction and are continuous at the head and tail, and the buckle tips 2131 of the second anti-loosening hooks 213 can be tightly buckled in the buckle valleys 1513 between two adjacent first anti-loosening hooks 151, so as to ensure the anti-loosening precision of the anti-loosening structure, strictly inhibit the reverse loosening phenomenon between the upper cover body 1 and the lower cover body 2, and the second anti-loosening hooks 213 are distributed in a circumferential direction, which is mainly to avoid the phenomenon that the output force increases when the upper cover body 1 and the lower cover body 2 are threadedly connected due to the setting of the anti-loosening structure, so as to ensure the anti-loosening and not increase the labor intensity of the operator.

[0019] Preferably, the anti-misoperation reservoir type bottle cap is provided with a second anti-loosening structure between the upper cover body 1 and the lower cover body 2, the second anti-loosening structure comprises first threaded bosses 1211 and second threaded bosses 215; the first threaded bosses 1211 are arranged in the valleys between adjacent upper and lower threaded turns in the upper cover inner thread 121, and N first threaded bosses 1211 are arranged in a circumferential direction; the lower cover outer thread 211 is N segmented threads arranged in a spiral, that is, the lower cover outer thread 211 is composed of N segmented threads, and the end of each segmented thread of the lower cover outer thread 211 contains a second threaded boss 215 (the lower cover outer thread 211 contains N second threaded bosses 215 in total), wherein N is any natural number in 1-4; during the threaded connection of the upper cover body 1 and the lower cover body 2, the segmented lower cover outer thread 211 avoids the first threaded boss 1211 (that is, the first threaded boss 1211 just passes through the gap position between adjacent segmented threads) when being threadedly and spirally lifted in the upper cover inner thread 121, and the first threaded boss 1211 is located in front of the second threaded boss 215 at the terminal position of the spiral lifting, so as to avoid the leakage of the formula substance in the storage cavity due to the reverse rotation and threading of the upper cover body 1 and the lower cover body 2 caused by artificial error operation or vibration during storage and transportation before use.

[0020] Preferably, the anti-misoperation reservoir type bottle cap has a third anti-loosening structure between the upper cap body 1 and the lower cap body 2, and the third anti-loosening structure comprises M first positioning protrusions 162 and M second positioning protrusions 214. The first positioning protrusions 162 are long-strip-shaped and located on the outer side of the circular piercing structure 16, extend along the central axis of the circular piercing structure 16, and are arranged at equal angles along the circumferential direction. The second positioning protrusions 214 are located on the inner side of the connecting ring 21, and the M second positioning protrusions 214 are arranged at equal angles along the circumferential direction. During the movement of the upper cap body 1 towards the lower cap body 2 after the C-shaped ring 15 is separated from the upper cap cylindrical cover 12, the first positioning protrusions 162 and the second positioning protrusions 214 approach along a spiral track in the vertical direction. When the piercing teeth 161 pierce the isolation sheet 23, the M first positioning protrusions 162 and the M second positioning protrusions 214 are in a state of mutual interference. The contact starting point of a single first positioning protrusion 162 and a single second positioning protrusion 214 is that a first arc surface 1621 in the first positioning protrusion 162 first passes a second arc surface 2141 in the second positioning protrusion 214. The contact ending point is that a first flat end surface 1622 in the first positioning protrusion 162 and a second flat end surface 2142 in the second positioning protrusion 214 are buckled and connected.

[0021] After the C-shaped ring 15 is separated from the upper cap body 1, during the movement of the upper cap body 1 towards the lower cap body 2 by screwing, after the piercing teeth 161 pierce the isolation sheet 23, the first positioning protrusions 162 and the second positioning protrusions 214 approach along a spiral track and finally buckle the flat end surfaces of the two positioning protrusions. When the user needs to separate the entire reservoir type bottle cap from the bottle body, whether the upper cap body 1 or the lower cap body 2 is screwed, the purpose of separating the entire bottle cap from the bottle body can be achieved. The buckling effect of the third anti-loosening structure prevents the relative separation of the upper cap body 1 and the lower cap body 2 due to reverse operation, avoids the secondary operation of the user, and ensures that the separation operation of the bottle cap and the bottle body is completed at one time.

[0022] Preferably, the anti-misoperation reservoir type bottle cap has a third anti-loosening structure between the upper cap body 1 and the lower cap body 2, and the third anti-loosening structure comprises M first positioning protrusions 162 and M second positioning protrusions 214.

The second positioning protrusions 214 are located on the inner side of the connecting ring 21, and the M second positioning protrusions 214 are arranged at equal angles along the circumferential direction. During the movement of the upper cap body 1 towards the lower cap body 2 after the C-shaped ring 15 is separated from the upper cap cylindrical cover 12, the first positioning protrusions 162 and the second positioning protrusions 214 approach along a spiral track in the vertical direction. When the piercing teeth 161 pierce the isolation sheet 23, the M first positioning protrusions 162 and the M second positioning protrusions 214 are in a state of mutual interference. The contact starting point of a single first positioning protrusion 162 and a single second positioning protrusion 214 is that a first arc surface 1621 in the first positioning protrusion 162 first passes a second arc surface 2141 in the second positioning protrusion 214. The contact ending point is that a first flat end surface 1622 in the first positioning protrusion 162 and a second flat end surface 2142 in the second positioning protrusion 214 are buckled and connected. M is a natural number of 2-5.

[0023] Preferably, the anti-misoperation reservoir type bottle cap has a third anti-loosening structure between the upper cap body 1 and the lower cap body 2, and the third anti-loosening structure comprises M first positioning protrusions 162 and M second positioning protrusions 214. The first positioning protrusions 162 are long-strip-shaped and located on the outer side of the circular piercing structure 16, extend along the central axis of the circular piercing structure 16, and are arranged at equal angles along the circumferential direction. The second positioning protrusions 214 are located on the inner side of the connecting ring 21, and the M second positioning protrusions 214 are arranged at equal angles along the circumferential direction. During the movement of the upper cap body 1 towards the lower cap body 2 after the C-shaped ring 15 is separated from the upper cap cylindrical cover 12, the first positioning protrusions 162 and the second positioning protrusions 214 approach along a spiral track in the vertical direction. When the piercing teeth 161 pierce the isolation sheet 23, the M first positioning protrusions 162 and the M second positioning protrusions 214 are in a state of mutual interference. The contact starting point of a single first positioning protrusion 162 and a single second positioning protrusion 214 is that a first arc surface 1621 in the first positioning protrusion 162 first passes a second arc surface 2141 in the second positioning protrusion 214. The contact ending point is that a first flat end surface 1622 in the first positioning protrusion 162 and a second flat end surface 2142 in the second positioning protrusion 214 are buckled and connected. M is a natural number of 2-5.

[0024] According to multiple piercing experiments, when the ratio is between 0.25 and 0.5: the piercing force of the saw-tooth is moderate, the isolation sheet 23 is partially separated from the lower cover body 2 after piercing; the piercing force of the dense small teeth is relatively large, the isolation sheet 23 is completely separated from the lower cover body 2 after piercing or is partially separated; the piercing force of the knife-type teeth is relatively large, the isolation sheet 23 is partially separated from the lower cover body 2 after piercing; the piercing force of the knife-type teeth with guide columns is relatively large, the isolation sheet 23 is partially separated from the lower cover body 2 after piercing. When the ratio is between 0.5 and 1: the piercing force of the saw-tooth is moderate, the isolation sheet 23 is completely separated from the lower cover body 2 after piercing; the piercing force of the dense small teeth is relatively large, the isolation sheet 23 is completely separated from the lower cover body 2 after piercing; the piercing force of the knife-type teeth is relatively large, the isolation sheet 23 is completely separated from the lower cover body 2 after piercing; the piercing force of the knife-type teeth with guide columns is relatively large, the isolation sheet 23 is completely separated from the lower cover body 2 after piercing. When specifically designing, the piercing teeth can be reasonably selected according to the requirements of the customer on the basis of ensuring that the piercing teeth are simple to process, the size of the piercing force and whether the isolation sheet 23 is allowed to be completely separated from the lower cover body 2.
