Description

TECHNICAL FIELD

[0001] The present scheme belongs to the technical field of packaging structure design, and particularly relates to a packaging system allowing built-in concentrated refill. BACKGROUND

[0002] Trigger sprayers are usually shipped and sold as an integral product with the bottle and its internal solution. Because the sprayer is expensive and is intended to be reused, the bottle is combined with the cap as a separate product for shipping and selling as a refill, which is replaced when the original solution is used up. With the rise of the environmental protection movement, the bottle refill product is being concentrated, forming a small size concentrated refill product, which undoubtedly reduces transportation costs and resource consumption, achieving the purpose of environmental protection. However, concentrated liquid is a high-concentration liquid product, and how to refill it into the bottle of the sprayer while ensuring safety is a problem. This problem has also been noticed, for example, as disclosed in the prior art documents US6290100 B1 and CN109606913 B, which attempt to solve this problem by completely placing the concentrated liquid device into the bottle for release, and the hand can not come into contact with the concentrated liquid, which indeed achieves good results in terms of safety. However, since the trigger sprayer has a liquid transfer straw, when installing the concentrated liquid device, the sprayer usually needs to be removed, and the long straw is taken out and then inserted into the small hole of the concentrated liquid device, which is not easy. Moreover, during the installation of the concentrated device, the straw with residual liquid is easily contaminated when it is taken out of the bottle, and how to place it is also a problem. As disclosed in the prior art document CN105358258 B, a method for adding concentrated liquid to the sprayer body is invented, without removing the sprayer from the bottle, that is, there is no problem of taking out and inserting the straw. However, this has brought about a first problem, that is, the installation of high-concentration concentrated liquid may still contaminate the operating environment or cause safety problems. In summary, the prior art does not solve the problem well. The present technical scheme has taken the above prior art into the reference and improvement range. For electric sprayers, which have higher reuse value, a more convenient and safe concentrated liquid refill device is needed. SUMMARY

[0003] The present scheme aims to overcome at least one defect (shortcoming) in the prior art and provide a packaging system allowing built-in concentrated refill, which is used to solve the problems of straw residual liquid contamination and installation convenience, as well as the problems of high-concentration contamination and safety.

[0004] In order to solve the above technical problems, the following technical scheme is adopted:

[0005] A package system allowing built-in concentrated supplement refill, comprising a first container and a pumping mechanism; the first container is provided with a first opening; the pumping mechanism comprises a pump head and a suction tube; the pump head has a liquid inlet and detachably seals the first opening; a free end of the suction tube extends into a bottom of the first container; further comprising a support, the suction tube is fixed in the first container through the support; the support comprises a body and a docking tube, the body is fixed to the first container, leaving a receiving space between the body and the pump head for detachably arranging the concentrated supplement refill, the concentrated supplement refill is arranged in place, and the concentrated supplement is released into the first container through the body; the fixed end of the docking tube is fixed to the body, and the free end of the docking tube penetrates the receiving space and docks with the liquid inlet; the fixed end of the suction tube is fixed to the body and / or the docking tube and docks with the fixed end of the docking tube.

[0006] In the scheme, the suction tube is fixed in the first container through the support, so when the pump head is detached, the suction tube does not need to be taken out and will not be taken out, avoiding pollution of the use environment by residual liquid in the suction tube; when the pump head is installed, the slender suction tube does not need to be inserted into the through pipeline of the concentrated supplement refill, avoiding pollution of the upper surface of the concentrated supplement refill by residual liquid attached to the outer surface of the suction tube, causing pollution of the hands when replacing the concentrated supplement refill next time, and also improving the convenience of installing the pump head. At the same time, the receiving space is left between the support and the liquid inlet for arranging the concentrated supplement refill, and the concentrated supplement is released after the concentrated supplement refill is arranged in place, so that the hands can not contact the high-concentration concentrated supplement and even be hurt, and the replacement process is safer.

[0007] The suction tube fixed in the first container is not directly connected to the liquid inlet, but indirectly connected to the liquid inlet through the docking tube on the support, so that the suction tube will not be taken out when the pump head is detached. When the package system is used to package a mixed liquid to form an original product, it is not necessary to arrange the concentrated supplement refill, that is, the manufacturer can directly fill the mixed liquid after dilution or without concentration in the first container, and after the concentrated supplement refill is released, the concentrated supplement refill can be removed without leaving the concentrated supplement refill in the package system. Of course, the manufacturer and the consumer can also choose to leave the concentrated supplement refill in the package system, that is, the package system also comprises the concentrated supplement refill; the concentrated supplement refill is detachably arranged in the receiving space, and is provided with a through pipeline to avoid the docking tube.

[0008] The part of the docking tube located in the receiving space can be configured as a first section for docking the liquid inlet and a second section for docking the suction tube, and the outer diameter of the first section d 1, the outer diameter of the second section d 2, and the inner diameter of the through pipeline D satisfy: d 1 / 2 d 2 D ; the through pipeline is provided with a foolproof convex part close to the liquid inlet, and the distance a between the foolproof convex part and the axis of the through pipeline satisfies: d 1 / 2 a ​d 2 / 2; the foolproof convex part divides the through pipeline into a section A close to the liquid inlet and a section B far from the liquid inlet, the length of the section A is l A the length of the section B l 2 satisfies: l A < l 2. When the side close to the foolproof convex part is upward, the docking pipe can smoothly pass through the through pipeline of the concentrated supplement, so that the concentrated supplement can be completely placed; on the contrary, when the side close to the foolproof convex part is downward, the second section of the docking pipe will interfere with the through pipeline, so that the concentrated supplement cannot be completely placed, thus playing a foolproof role.

[0009] The concentrated supplement includes a second container and a sealing member, and the through pipeline is arranged on the second container and penetrates the second container. The second container is used for containing the concentrate, and a second opening avoiding the through pipeline is arranged on the side of the second container facing the bottom of the first container. The sealing member seals the second opening before the concentrated supplement is installed in place, so that the concentrate can be well packaged and stored. The body is provided with an unsealing convex part corresponding to the sealing member, so as to unseal the sealing member of the concentrated supplement arranged in place, so that the concentrate can be transferred from the second container to the first container, and the transfer starts when the concentrated supplement is arranged in place, which can avoid the hand from contacting the high-concentration concentrate and even causing injury, and the replacement process is safer. Preferably, the sealing member is provided with a tear line corresponding to the unsealing convex part, or the sealing member is additionally provided with a movable inner plug type part corresponding to the unsealing convex part, which reduces the difficulty of the unsealing convex part to unseal the sealing member. More preferably, a protective convex ring exists at the sealing end of the second container, the protective convex ring surrounds the sealing member and protrudes from the side of the sealing member away from the second opening, so as to protect the sealing member from being unsealed during transportation, especially for the sealing member with a tear structure or a tear line, to prevent it from being damaged under stress.

[0010] The body can be configured as a basket structure having a basket opening, a basket wall and a basket bottom. The basket wall is connected to the first opening, and the basket opening is detachably sealed by the pump head. The pump head, the basket wall and the basket bottom form the above-mentioned accommodation space, and the fixed end of the docking pipe is fixed to the basket bottom. No matter whether the first container is configured as a bottle, a jar, a cup or other utensils, the bracket can be conveniently fixed to the first container. Specifically, the basket wall and the first opening can be connected by a clamping structure, a threaded structure, an interference fit or the like. The connection can be arranged at both ends or the middle of the basket wall. If the end of the basket wall close to the basket opening is connected to the first opening, the pump head can be connected to the first opening, thereby directly sealing the first opening. If the part of the basket wall away from the basket opening is connected to the first opening, the pump head can be connected to the basket opening, thereby indirectly sealing the first opening.

[0011] Preferably, the pump head directly or indirectly seals the first opening by a threaded cap. If the pump head directly seals the first opening, the threads cooperating with the threaded cap are arranged on the first opening; if the pump head indirectly seals the first opening, the threads cooperating with the threaded cap are arranged on the portion of the basket wall close to the basket opening. For a packaging system that needs to be repeatedly disassembled, the first opening is detachably sealed by the threaded cap, which helps to prolong the service life. For the concentrated supplement package that is opened by extrusion of the unsealing protrusion, the sealing by the threaded cap can rely on the extrusion of the concentrated supplement package during the tightening of the threaded cap to facilitate the arrangement of the concentrated supplement package, which helps to reduce the assembly difficulty and facilitate the user to replace the concentrated supplement package.

[0012] Preferably, the outer side of the basket wall is provided with a flange, and the outer diameter of the flange is greater than the inner diameter of the first opening, so as to abut against the end face of the first opening. The flange can play a positioning role to confirm that the connection between the bracket and the first opening is in place, and can even play a supporting role, especially when the basket wall and the first opening are connected by an interference fit, which can prevent the concentrated supplement package from being extruded and causing the bracket to move towards the bottom of the first container due to excessive stress.

[0013] The pump head can be customized as needed, or a commercially available sprayer, press pump, etc. can be selected. Among them, the size, position and other parameters of the liquid inlet of the commercially available sprayer, press pump, etc. are not standard, especially when the liquid inlet is not centrally arranged, the free end of the adapter pipe is connected to the liquid inlet through an adapter, and the adapter is provided in a stepped cylinder structure, the large end of which is fixed to the pump head and clamps the liquid inlet, and the small end of which is connected to the adapter pipe. The adapter is also provided with a gas return channel of the first container, which realizes the communication between the first container and the pump head gas return port.

[0014] Compared with the prior art, the present scheme has the following beneficial effects: the straw is fixed in the first container by the bracket, and a containing space for placing the concentrated supplement package is left, and the straw does not need to be taken out when the pump head is disassembled, solving the problems of residual liquid pollution and installation convenience. At the same time, the concentrated substance is released after the concentrated supplement package enters the first container, solving the problems of high concentration pollution and safety.

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the present scheme, the present scheme will be further described in detail below in combination with specific embodiments.

[0033] Figures 1-6 A first embodiment of the packaging system allowing the built-in concentrated supplement is illustrated. Please refer to Figure 1 The packaging system allowing the built-in concentrated supplement of the present embodiment comprises a first container 100, a pumping mechanism, a bracket and a concentrated supplement 400.

[0034] The first container 100 is a bottle for containing liquid, which is diluent or mixture of diluent and concentrate. The first container 100 is provided with a first opening 110 for liquid to enter or exit the first container 100.

[0035] The pumping mechanism comprises a pump head 210 and a suction tube 220. The pump head 210 is a trigger type manual sprayer or an electric sprayer, which detachably seals the first opening 110 and has a liquid inlet 211 located in the space enclosed by the pump head 210 and the first container 100. The suction tube 220 is fixed in the first container 100 by the bracket, with its free end extending into the bottom of the first container 100.

[0036] The bracket comprises a body 310 and a connecting tube 320. The body 310 is fixed to the first container 100, with an accommodating space 3100 left between the body 310 and the pump head 210. The fixed end of the connecting tube 320 is fixed to the body 310, with its free end penetrating the accommodating space 3100 to connect the liquid inlet 211. The fixed end of the suction tube 220 is fixed to the connecting tube 320 and connected to the fixed end of the connecting tube 320, so as to be fixed in the first container 100 and communicate with the liquid inlet 211 through the connecting tube 320.

[0037] The concentrated supplement 400 is used to temporarily store the concentrate, which is a high-concentration liquid product or a solid product. The concentrated supplement 400 is detachably arranged in the above-mentioned accommodation space 3100, and after being arranged in place, the concentrate is released into the first container 100 through the body 310. The concentrated supplement 400 is provided with a through pipeline 411 to avoid the above-mentioned butt joint pipeline 320.

[0038] The suction pipe 220 is fixed in the first container 100 by the bracket, and when the pump head 210 is detached, the suction pipe 220 does not need to be taken out and will not be taken out, avoiding the pollution of the residual liquid of the suction pipe 220 to the use environment; when the pump head 210 is installed, the slender suction pipe 220 does not need to be inserted into the through pipeline 411 of the concentrated supplement 400, avoiding the pollution of the residual liquid attached to the outer surface of the suction pipe 220 to the upper surface of the concentrated supplement 400, causing the pollution of the hands when replacing the concentrated supplement 400 next time, and also improving the convenience of installing the pump head 210. At the same time, the bracket and the liquid inlet 211 are left with an accommodation space 3100 to arrange the concentrated supplement 400, and the concentrated supplement 400 is arranged in place to release the concentrate, which can avoid the hands from contacting the high-concentration concentrate and even causing injury, and the replacement process is safer.

[0039] Please refer to Figures 2-3 The body 310 is arranged as a basket structure with a basket opening 311, a basket wall 312 and a basket bottom 313. The basket structure is placed in the first container 100 from the first opening 110, and the part of the basket wall 312 close to the basket opening 311 is interference-fitted with the first opening 110, so that the bracket is conveniently fixed in the first container 100. As Figures 4-5As shown, the outer side of the basket wall 312 is provided with a flange 330 flush with the basket opening 311, and the outer diameter of the flange 330 is greater than the inner diameter of the first opening 110, so as to abut against the end face of the first opening 110. The flange 330 can play a positioning role to confirm the connection between the bracket and the first opening 110 in place, and also play a supporting role to avoid the bracket from moving to the bottom of the first container 100 due to extrusion by the concentrated supplement 400. The basket opening 311 is detachably closed by the pump head 210, and the pump head 210, the basket wall 312 and the basket bottom 313 enclose to form the above-mentioned accommodation space 3100, and any cross section of the basket wall 312 is adapted to the shape of the first opening 110, so as to provide as large an accommodation space 3100 as possible to install the concentrated supplement 400. The fixed end of the docking pipe 320 is fixed to the basket bottom 313 and extends from the inner side of the basket bottom 313 to the outer side of the basket bottom 313, and the part located on the outer side of the basket bottom 313 can be inserted into the suction pipe 220, so as to realize the fixation and docking of the suction pipe 220. In addition, the suction pipe 220 can also be fixed by the body 310 or fixed by the body 310 and the docking pipe 320 together, and docked with the fixed end of the docking pipe 320. The basket bottom 313 is provided with a window 3131 avoiding the docking pipe 320, which realizes the communication between the accommodation space 3100 and the first container 100, so that the concentrated supplement 400 arranged in place releases the concentrate to the first container 100 through the body 310.

[0040] Please refer to Figures 6-7 The part of the docking pipe 320 located in the accommodation space 3100 is configured as two sections with different outer diameters, which are the first section for docking the liquid inlet 211 and the second section for docking the suction pipe 220, and the outer diameter of the first section d 1 d 2 D and the inner diameter of the through pipeline 411 satisfy: d 1 d 2 D ; the through pipeline 411 is provided with a foolproof convex part 412 close to the liquid inlet 211, and the distance between the foolproof convex part 412 and the axis of the through pipeline 411 satisfies: a 1 / 2 d < a 2 / 2; the foolproof convex part 412 divides the through pipeline 411 into an A section close to the liquid inlet 211 and a B section away from the liquid inlet 211, and the length of the A section d A and the length of the second section l 2 l A satisfy: l l2. When the concentrated supplement 400 is arranged, the side close to the anti-fool convex part 412 is upward, the connecting pipe 320 can be smoothly inserted into the through pipe 411 of the concentrated supplement 400, so that the concentrated supplement 400 can be completely placed; on the contrary, the side close to the anti-fool convex part 412 is downward, the second section of the connecting pipe 320 and the anti-fool convex part 412 will interfere, so that the concentrated supplement 400 cannot be completely placed, thus playing the role of anti-fool.

[0041] Please refer to Figures 8-10 , the concentrated supplement 400 includes a second container 410 and a sealing member 420, and the through pipe 411 is arranged on the second container 410 and penetrates the second container 410. The second container 410 is used for containing the concentrate, and the side of the second container 410 facing the bottom of the first container 100 is provided with a second opening 413 avoiding the through pipe 411. The sealing member 420 seals the second opening 413 before the concentrated supplement 400 is arranged in place, so that the concentrate can be well packaged and stored. The inside of the basket bottom 313 is provided with an unsealing convex part 340 corresponding to the sealing member 420, so as to unseal the sealing member 420 of the concentrated supplement 400 arranged in place, so that the concentrate can be transferred from the second container 410 to the first container 100, and the transfer starts when the concentrated supplement 400 is arranged in place, which can avoid the hand from contacting the high-concentration concentrate and even causing injury, and the replacement process is safer. The outside of the basket bottom 313 and the connecting pipe 320 are provided with a reinforcing rib plate 350 corresponding to the unsealing convex part 340, which is beneficial to improve the pressure resistance of the unsealing convex part 340 and even the whole bracket, and improve the service life of the bracket and even the packaging system.

[0042] The sealing member 420 and the second opening 413 are sealed by welding. In addition, the sealing member 420 and the second opening 413 can also be sealed by a sealing ring 430. The sealing member 420 is provided with a tear line 421 corresponding to the unsealing convex part 340, which reduces the difficulty of opening the sealing member 420 by the unsealing convex part 340. In addition, the sealing member 420 can also be additionally provided with a removable inner plug type part 422 corresponding to the unsealing convex part 340, such as Figure 10 , which also reduces the difficulty of opening the sealing member 420 by the unsealing convex part 340. The sealing end of the second container 410 has a protective convex ring 440, which surrounds the sealing member 420, protrudes from the side of the sealing member 420 away from the second opening 413 and is integrated with the sealing member 420, protects the sealing member 420 from being easily opened during transportation, and prevents the tear line 421 from being damaged under stress. In addition, the protective convex ring 440 can also be integrated with the second container 410.

[0043] The second container 410 is shaped to fit the accommodation space 3100, and its height is comparable to the depth of the accommodation space 3100, ensuring that the pump head 210 can be installed in place with the first opening 110 in a sealed state, and that the second container 410 can be subjected to a force to enable the concentrated supplement 400 to be fitted in place. The cross section of the second container 410 is slightly smaller than the cross section of the accommodation space 3100, achieving maximum capacity of the second container 410.

[0044] The pump head 210 directly seals the first opening 110 by means of the threaded cap 213, and the threads configured to cooperate with the threaded cap 213 are arranged at the first opening 110. For the present packaging system which needs to be repeatedly disassembled and assembled, the threaded cap 213 is used to detachably seal the first opening 110, which helps to prolong the service life. Moreover, due to the presence of the unsealing protrusion 340, the concentrated supplement 400 in the present packaging system needs to be fitted in place under the action of an external force. By sealing with the threaded cap 213, the concentrated supplement 400 can be fitted in place by relying on the extrusion of the concentrated supplement 400 during the tightening process of the threaded cap 213, as shown in Figure 11 , which helps to reduce the difficulty of assembly and facilitates the user to replace the concentrated supplement 400.

[0045] Figures 12-14 A second embodiment of a packaging system allowing the built-in concentrated supplement is illustrated. For a general pump head 210, especially a commercially available trigger-type sprayer, the inner diameter of the threaded cap 213 is small, and the inner diameter of the first opening 110 of the first container 100 matched therewith is also small. On this basis, increasing the support will result in a smaller capacity of the concentrated supplement 400, and the concentration of the mixed liquid cannot meet the dilution requirements. Therefore, in the present embodiment, the part used to cooperate with the threaded cap 213 is arranged on the support, so as to increase the accommodation space 3100.

[0046] The packaging system allowing the built-in concentrated supplement of the present embodiment is basically the same as the first embodiment, and also includes the first container 100, the pumping mechanism, the support and the concentrated supplement 400. The support includes the body 310 and the docking pipe 320, and the body 310 is configured as a basket structure having the basket opening 311, the basket wall 312 and the basket bottom 313. The main difference is that please refer to Figures 12-14The middle outer side of the basket wall 312 is provided with a flange 330, the outer diameter of the flange 330 is greater than the inner diameter of the first opening 110, so as to abut the end face of the first opening 110, and play a positioning role, so as to confirm the connection between the bracket and the first opening 110. The basket wall 312 and the first opening 110 or the flange 330 and the first opening 110 are provided with a clamping structure 360, which realizes the sealed connection / welding of the bracket and the first opening 110. The part of the basket wall 312 close to the basket opening 311 is provided with a thread, and the pump head 210 is connected with the thread through the threaded cover 213, so as to detachably close the basket opening 311, and indirectly close the first opening 110 in combination with the bracket body 310. For the present packaging system which needs to be repeatedly disassembled, detachably closing the basket opening 311 through the threaded cover 213 helps to prolong the service life. Moreover, due to the existence of the unsealing convex part 340, the concentrated supplement 400 in the present packaging system needs to be configured in place under the action of external force, and through the closure of the threaded cover 213, the configuration of the concentrated supplement 400 in place can be promoted by the extrusion of the concentrated supplement 400 in the tightening process of the threaded cover 213, which helps to reduce the assembly difficulty and facilitates the user to replace the concentrated supplement 400.

[0047] It should be noted that the straw 220 fixed in the first container 100 in the above-mentioned embodiment is not directly connected to the liquid inlet 211, but is indirectly connected to the liquid inlet 211 through the docking pipe 320 on the bracket, so that the straw 220 will not be taken out when the pump head 210 is disassembled. When the present packaging system is used to package a mixed liquid to form an original product, the concentrated supplement 400 does not need to be configured, that is, the manufacturer can directly fill the mixed liquid after dilution or without concentration in the first container 100, and when the concentrated supplement 400 is replaced later, the concentrated supplement 400 can also be removed after the concentrated material in the concentrated supplement 400 is released, and it is not necessary to keep the concentrated supplement 400 in the packaging system.

[0048] In addition, the pump head 210 can be customized as needed, or a commercially available sprayer, press pump, etc. can be selected. Among them, the size, position and other parameters of the liquid inlet 211 of the commercially available sprayer, press pump, etc. are not standard, especially when the liquid inlet 211 is not centrally arranged, the free end of the docking pipe 320 can be connected to the liquid inlet 211 through an adapter 230, as shown in Figure 15 The adapter 230 is provided as a stepped cylinder structure, the large end of which is fixed on the pump head 210 and buckles the liquid inlet 211, and the small end thereof is connected to the docking pipe 320. The adapter 230 is also provided with a gas return channel 232, which realizes the communication between the first container 100 and the gas return port 212 on the pump head 210. It can be understood that if the adapter 230 does not cover the gas return port 212 of the pump head 210, that is, the first container 100 can be connected to the gas return port 212 from the outside of the adapter 230, then the adapter 230 does not need to be provided with the gas return channel 232.

[0049] Obviously, the above embodiments of the present application are merely exemplary but not intended to limit the embodiments of the present application. Based on the above description, any other variations or modifications of the embodiments can be made by those skilled in the art without departing from the spirit and principles of the present application. It is to be understood that the present application is not limited to the above-described embodiments but covers any modifications or variations thereof within the spirit and principles of the present application.
