Most liquid products are designed to have a proper concentration for use, but have very low levels of actual active ingredients. With the rise of environmental protection movement, similar products are being designed into concentrated liquid with a certain proportion, and the concentrated liquid is released into a dilution container to be mixed with purified water according to a set proportion when in use. Compared with the product with normal concentration ratio, the concentrated product can reduce the packaging and transportation cost, reduce the resource consumption and achieve the aim of environmental protection. However, the concentrated solution is a high-concentration liquid product, and it is a problem how to ensure the safety of storage and transportation, and how to conveniently and safely introduce the concentrated solution into a dilution container, while meeting the goals of high efficiency and low cost. This problem is also of interest, and for example, the technical solution described in patent document CN113853345B attempts to solve this problem by realizing the butt joint of the concentrating container and the diluting container by the cap assembly, and unsealing the container by pushing the closure member against the stopper provided between the cap assembly and the diluting container in the process of moving the two in opposite directions, and the concentrated solution in the concentrating container is directly released into the diluting container after unsealing, so that the concentrated solution can not be touched by a human hand, and a good effect can be obtained in terms of safety. However, since the closing member is in an unconstrained state after being pushed open, the conduit may be blocked, affecting the release rate of the container, and the presence of the stopper may block the release of the concentrate, resulting in that part of the concentrate may not be used.

The docking member 110 is configured as a cylindrical structure having a first end for docking the first container 310 and a second end for docking the second opening 411 of the second container 410, thereby enabling docking of the first container 310 with the second container 410. The liquid outlet 130 is configured as a cylindrical structure coaxially disposed in the docking member 110, and has a first end for communicating with the interior of the first container 310 and a second end for communicating with the interior of the second container 410, so as to achieve communication between the interior of the first container 310 and the interior of the second container 410. The liquid outlet nozzle 130 is fixed in the butt joint member 110 through the annular connecting member 120, the inner ring of the connecting member 120 is connected with the first end of the liquid outlet nozzle 130, and the outer ring is connected with the inner wall of the butt joint member 110, so that the communication between the interior of the first container 310 and the interior of the second container 410 can only be realized through the liquid outlet nozzle 130.
The end cover 150 is fixed outside the liquid outlet nozzle 130 by the bracket 140 and coaxially arranged in the abutting part 110, a first section of the bracket 140 is positioned in the liquid outlet nozzle 130 and fixed on the inner wall of the liquid outlet nozzle 130, and a second end of the bracket extends outwards from a second end of the liquid outlet nozzle 130 and is connected with a first end of the end cover 150. The side cover 210 is configured as a tubular structure, coaxially sleeved outside the liquid outlet nozzle 130 and the end cover 150, wherein the inner wall of the first section is in interference fit with the outer wall of the liquid outlet nozzle 130, and the inner wall of the second section is in interference fit with the outer wall of the end cover 150, so that the liquid outlet nozzle 130 is temporarily closed in cooperation with the end cover 150, the first liquid can be packaged well, and the sealing requirement of the storage and transportation process is met.
The outer wall of the side cover 210 is provided with a supporting portion 211 for bearing the pushing force applied by the second container 410 against the second opening 411 accessed from the second end of the docking member 110. A clearance space is reserved between the side cover 210 and the butt joint member 110, so as to avoid the side cover 210 which is moved towards the butt joint member 110 under the action of thrust. In the process that the side cover 210 enters the avoidance space, a release port is gradually formed between the side cover 210 and the end cover 150, and the first liquid is directly released into the second container 410 through the bracket 140 and the release port.
Whether in the closing stage or the unsealing stage, the side cover 210 is completely installed in the butt joint member 110, so that leakage caused by impact in the storage and transportation process can be prevented, and only after the second container 410 is in butt joint with the butt joint member 110, the side cover 210 can be pushed into the avoidance space to unseal, so that the problems of leakage pollution and safety of packaged liquid (particularly concentrated liquid) are solved. After unsealing, the side cover 210 and the end cover 150 are still restrained, and the distance between the side cover 210 and the end cover 150 is kept all the time, so that the smoothness of the liquid outlet nozzle 130 is ensured, and the quick release of the first liquid is facilitated. The release port is formed on the first end of the end cap 150 so that the first liquid does not accumulate on the end cap 150, which is advantageous in avoiding liquid residue.
In the container closure assembly, the butt 110, the liquid outlet 130 and the end cap 150 are integrally formed, and the outer diameter D of the end cap 150 1 And the inner diameter D of the liquid outlet nozzle 130 2 The following are satisfied: d (D) 1 ≤D 2 The die is beneficial to the design difficulty of the die and the manufacturing cost is saved.

Height h of second section of side cover 210 2 Outer wall of end cap 150The height H of (2) satisfies: h is a 2 And H is equal to or greater than 2mm, so that the tightness between the side cover 210 and the end cover 150 is improved, and the sealing effect on the liquid outlet nozzle 130 is improved. Height h of first section of side cover 210 1 And the axial distance B between the end cover 150 and the liquid outlet nozzle 130 satisfies the following conditions: h is a 1 B is more than or equal to 2mm, which is beneficial to improving the tightness between the side cover 210 and the liquid outlet nozzle 130, thereby improving the sealing effect on the liquid outlet nozzle 130.
In addition, if the outer diameter D of the end cap 150 1 And the outer diameter D of the liquid outlet nozzle 130 3 The following are satisfied: d (D) 1 ≥D 3 The inner diameter d of the first section of the side cover 210 1 With an inner diameter d of the second section thereof 2 The method meets the following conditions: d (D) 3 ≈d 1 ≤d 2 The liquid outlet nozzle 130 does not obstruct the movement of the side cover 210 even if the height h of the second section of the side cover 210 2 Beyond the axial distance B between the end cap 150 and the liquid outlet nozzle 130, a release opening can be ensured between the end cap 150 and the side cover 210.
The end cap 150 is configured in a cap-like structure that facilitates increasing the height of the end cap 150 to provide a sealing effect while ensuring uniform wall thickness throughout the entirety of the interface 110, the spout 130, and the end cap 150. The concave surface of the end cap 150 faces away from the liquid outlet nozzle 130, so that the second end of the bracket 140 can be directly connected with the first end of the end cap 150, and residual liquid is avoided. The first end of the end cap 150 may be a curved surface protruding toward the liquid outlet 130, or may be a tapered surface protruding toward the liquid outlet 130, which is advantageous for further avoiding liquid residue. Similarly, the first end of the connecting member 120 may be a conical surface concave toward the liquid outlet 130, or may be a curved surface concave toward the liquid outlet 130, which is beneficial to further avoiding liquid residue.

The second end of the strut 141 is connected to the first end of the end cap 150, and the first section is connected to the inner wall of the liquid outlet nozzle 130 through the rib plate 142, so that the first liquid directly flows along the inner wall of the liquid outlet nozzle 130 to the release port, and then is released into the second container 410, that is, the bracket 140 does not become a barrier for the first liquid, which is beneficial to further improving the release speed. The struts 141 are configured as solid cylinders, and when the diameter of the solid cylinder is small to a certain extent, the support 140 may be regarded as a structure composed of a plurality of rib plates 142 arranged in a circumferential array around the axis, the second end of each rib plate 142 is connected to the first end of the end cap 150, and the outer side of the first section is connected to the inner wall of the liquid outlet nozzle 130.
The second opening 411 of the second container 410 is generally provided with external threads so as to detachably close the second opening 411 by a common screw cap, a screw cap with a pump head, or the like.

Referring to FIGS. 7-8, the height h of the second opening 411 3 And the matching height h of the second opening 411 and the butt joint part 110 after unsealing in place 4 The method meets the following conditions: h is a 3 ＞h 4 The difference h between the two 3 －h 4 Just after unsealing in place, the fit clearance delta of the second container 410 and the docking member 110 2 The second opening 411 is screwed into the fit gap delta between the second container 410 and the butt piece 110 when the second opening is just contacted with the supporting portion 211 1 Just before and after unsealing, the moving travel t and the fit clearance delta of the side cover 210 2 And (3) summing.
Fig. 12 illustrates a second embodiment of a container closure assembly. The container closure structure of this embodiment is substantially the same as the first embodiment, and includes a butt joint 110, a spout 130, an end cap 150 and a side cap 210, and is also used to close a first container 310 (fig. 13 and 15), and can be unsealed only by the cooperation of a second container 410 (fig. 14 and 16), and the main difference is that: the side cover 210 is further provided with a screwing portion 212.
Referring to fig. 12 to 16, the screwing portion 212 is configured as a cylindrical structure, coaxially sleeved on the periphery of the side cover 210, and located at one side of the second end of the supporting portion 211, and the first end thereof is connected to the outer wall of the supporting portion 211. The outer wall of the screwing part 212 is used for being in threaded connection with the inner wall of the butt joint piece 110, so that the butt joint piece can be prevented from being extruded by other sharp objects to be opened by mistake, and the storage and transportation safety is further improved. The inner wall of the screwing part 212 is in threaded connection with the outer wall of the second opening 411, and after the second opening 411 and the screwing part 212 are screwed in place, continued screwing of the second opening 411 drives the screwing part 212 to screw in the abutting part 110, so that the side cover 210 is pushed to move towards the first container 310, and the closing position is switched to the unsealing position. When the second opening 411 is screwed into the supporting portion 211 and just contacts with the supporting portion 211, the screwing angle α of the external thread of the second opening 411 and the internal thread of the screwing portion 212 is greater than or equal to 90 °, that is, after the second opening 411 is screwed into the screwing portion 212 for more than or equal to one quarter turn, an acting force is applied to the supporting portion 211 to open the channel.
The first end of the supporting portion 211 and the surface of the connection member 120 facing the supporting portion 211 are respectively provided with first non-return structures 012 that are engaged with each other, and the first non-return structures 012 may be non-return ratchet teeth. After the side cover 210 is driven by the first opening 311 to be screwed in to a certain extent, the first non-return structure 012 on the supporting part 211 and the first non-return structure 012 on the connecting piece 120 are connected and locked; when the second container 410 is reversely rotated after the first liquid is released, the side cover 210 and the butt joint member 110 cannot rotate relatively with each other due to the first non-return structure 012, and the whole formed by the side cover 210 and the butt joint member 110 and the second container 410 can rotate relatively, so that the second container 410 can be directly detached from the butt joint member 110, and the using difficulty is reduced.
In both embodiments, the first member may be integrally formed with the first container 310, as shown in fig. 6-9 and 13-14; may be removably or non-removably mounted to the first container 310 as shown in fig. 10-11 and 15-16.
In the former case, the first container 310 is configured as a cylindrical structure, the second end of the first container is provided with a liquid outlet, the second end of the first container is closed by the container closing assembly, the first member is integrally formed at the liquid outlet, and the first end of the abutting member 110 abuts against the second end of the first container 310. The first end of the second container 410 is provided with a liquid inlet, which is convenient for the integral formation of the first container 310 and the first member, and is convenient for filling the first liquid, and then is closed by the cover 320.
In the latter case, the first container 310 may be configured as a conventional container such as a bottle having a first opening 311 for filling with the first liquid, which is then closed by the container closure assembly, and finally released into the second container 410 via the unsealed container closure assembly. The connection member 120 divides the docking member 110 into an I-th portion near the first end and an II-th portion near the second end, and the I-th portion is detachably coupled to the first opening 311 by a screw coupling or the like, so that the docking member 110, the liquid outlet 130, and the cap 150 are detachably mounted on the first container 310. A second non-return structure 023, such as a non-return ratchet, is disposed between the docking member 110 and the first container 310, so that the docking member 110 forms an integral body with the first container 310 after being mounted in place on the first container 310, thereby realizing non-detachable mounting and preventing misoperation. The connector 120 has a cylindrical abutting portion 121 disposed on a surface facing the first container 310, and an outer wall of the abutting portion 121 is configured to be engaged with an inner wall of the first opening 311. The connector 120, the abutting portion 121, or both are provided with a sealing ring on a surface facing the first opening 311 for sealing connection with the first opening 311.
