Detailed Description
In order to better understand the present solution, a further detailed description of the present solution will be provided below in conjunction with specific embodiments.
Fig. 1 to 3 illustrate a first embodiment of a container closure structure, which comprises a sealing plug 100. The container closure is used to removably close a first container 400 having a spout 300 and a docking member 200 to form a packaging system for use therewith, as shown in fig. 4; the packaging system can only be unsealed with the cooperation of the second container 500, resulting in a further packaging system, as shown in fig. 5-6.
Referring to fig. 4, a first container 400 is used to hold a first liquid, particularly a concentrate (high-strength liquid product). The docking member 200 is configured as a cylindrical structure with a first end connected to the first container 400 and a second end for accessing the sealing plug 100 and the liquid inlet 510 of the second container 500, thereby enabling docking of the first container 400 with the second container 500. The liquid outlet 300 is configured as a cylindrical structure coaxially disposed in the docking member 200, and has a first end communicating with the interior of the first container 400 and a second end for communicating with the interior of the second container 500, thereby enabling communication between the interior of the first container 400 and the interior of the second container 500.
Referring to fig. 5 to 6, the second container 500 is used for containing a second liquid, or a mixture of the second liquid and the first liquid, and the second liquid may be a diluent, such as water, for diluting the concentrated solution. The second container 500 is provided with a liquid inlet 510 for liquid to enter and exit the second container 500, in particular for the first liquid packed in the first container 400 to enter the second container 500. The outer wall of the inlet 510 is typically provided with external threads to removably close the inlet 510 with a conventional screw cap, screw cap with a pump head, or the like. Accordingly, the inner wall of the docking member 200 may be provided with external threads having a diameter and lead adapted to the external threads of the inlet 510 so that the docking member 200 is screwed into engagement with the inlet 510 of the second container 500.
Referring to fig. 1 to 6, the sealing plug 100 includes a sealing portion 110, an engagement portion 120, and a supporting portion 130 coaxially disposed. In use, the first end of the sealing plug 100 and its components are oriented toward the first container 400 and the second end is oriented toward the second container 500.
The sealing part 110 is configured as a cap-like structure, and the outer wall thereof is used for interference fit with the inner wall of the liquid outlet nozzle 300, so as to detachably close the liquid outlet nozzle 300, so that the first liquid can be completely packaged in the first container 400, and the sealing requirement of the storage and transportation process is met. The engaging portion 120 is configured as a cylindrical structure, and an inner wall thereof is used to engage an outer wall of the liquid outlet 300. The support 130 is configured as an annular structure, and a second end thereof is configured to abut against the liquid inlet 510 and bear the thrust force exerted by the liquid inlet 510.
The inner wall of the supporting portion 130 is connected with the outer wall and the second end of the connecting portion 120, the connecting portion 120 and the sealing portion 110 are arranged at a distance in the axial direction, one surface of the sealing portion 110 facing the connecting portion 120 is connected with the second end of the connecting portion 120 through the support 140 penetrating through the connecting portion 120, it is ensured that the pushing force applied to the supporting portion 130 can be transmitted to the sealing portion 110, the sealing portion 110 is separated from the liquid outlet 300 and enters the first container 400, the blocking of the liquid outlet 300 is eliminated, and finally a gap is reserved between the sealing portion 110 and the liquid outlet 300 for the first liquid to flow out, and the first liquid is released into the second container 500 through the support 140. The axial distance b between the joint portion 120 and the sealing portion 110 1 Less than or equal to the outletThe height H of the spout 300 is such that the engaging portion 120 starts to engage the spout 300 before the sealing portion 110 is pushed by the external force to completely disengage from the spout 300, so as to prevent the first liquid in the first container 400 from leaking out of the packaging system during the unsealing stage.
Whether in the closing stage or the unsealing stage, the sealing plug 100 is completely installed in the butt joint piece 200, so that leakage caused by impact in the storage and transportation process can be prevented, and only after the liquid inlet 510 of the second container 500 is in butt joint with the butt joint piece 200 and the joint part 120 is in joint with the liquid outlet 300, the sealing part 110 can be completely pushed into the first container 400 to realize unsealing, so that the leakage pollution and the safety problem of packaged liquid (particularly concentrated liquid) are solved. After unsealing, the sealing part 110 is still restrained by the bracket 140, and keeps a distance from the liquid outlet 300 all the time, so that the liquid outlet 300 is ensured to be smooth, and the quick release of the first liquid is facilitated.
In addition to the cap-like structure, the sealing portion 110 may be configured as a columnar structure, and the spout 300 may be detachably closed by interference fit of the outer wall with the inner wall of the spout 300. Height h of seal portion 110 1 Preferably, the following are satisfied: h is a 1 And is more than or equal to 2mm, which is beneficial to improving the sealing effect of the sealing part 110 on the liquid outlet 300. For a seal 110 of greater height, the configuration of a cap-like structure facilitates uniform wall thickness throughout the plug 100. The bracket 140 is connected to the concave surface of the sealing portion 110 of the cover structure, which is beneficial to reducing the difficulty of mold design and thus reducing the manufacturing cost.
Height h of the engagement portion 120 2 Preferably, the following are satisfied: h is a 2 The length of the connection part 120 and the liquid outlet 300 is larger than 2mm, which is favorable for increasing the connection length of the connection part and the liquid outlet 300, and further prevents the first liquid from leaking out in the unsealing stage. Distance b between sealing part 110 and liquid outlet 300 in axial direction after unsealing in place 2 Preferably, the following are satisfied: b 2 Is more than or equal to 2mm so as to improve the smoothness of the first liquid flowing out from the gap and increase the release speed of the first liquid.
Bracket 140 may be configured to include a structure of struts 141 and reinforcing ribs 142. Reinforcing ribs 142 are configured as three, but may be configured as four, five or more, arranged in a circumferential array about strut 141. The first end of the strut 141 is connected to the surface of the sealing portion 110 facing the engaging portion 120 and the supporting portion 130, and the portion near the second end is connected to the second end of the engaging portion 120 through the reinforcing rib plate 142, so that the first liquid flowing out of the gap is directly released to the second container 500 along the inner wall of the liquid outlet 300, that is, the bracket 140 does not become a barrier for the first liquid, which is beneficial to further improving the release speed and avoiding the liquid residue caused by the existence of the sealing plug 100.
The struts 141 are configured as cylindrical structures, but may also be configured as solid cylinders. When the diameter of the solid cylinder is small to a certain extent, the bracket 140 may be regarded as a structure composed of a plurality of reinforcing ribs 142 arranged in an array around the axial direction, wherein a first end of each reinforcing rib 142 is connected to a face of the sealing portion 110 facing the engaging portion 120 and the supporting portion 130, and a portion near the second end is connected to the second end of the engaging portion 120. The cylindrical structure of the pillar 141 is advantageous in that the diameter of the pillar 141 is designed to be relatively large in order to enhance the supporting strength of the sealing portion 110 and in that the wall thickness of the sealing plug 100 is uniform throughout. The first end of each reinforcing rib plate 142 can be connected with one surface of the sealing portion 110 facing the connecting portion 120 and the supporting portion 130, and can be arranged at a distance from the sealing portion 110, the former is more beneficial to uniformly stressing the sealing portion 110, the unsealing difficulty is reduced, meanwhile, the mold design difficulty is also reduced, and the manufacturing cost is saved.

The drainage portion 150 is configured in a cylindrical structure, is disposed coaxially with the other portion of the sealing plug 100, and is located at one side of the second end of the engagement portion 120. The inner diameter D of the drainage part 150 is equal to or smaller than the inner diameter D of the liquid outlet 300 so as to guide the released first liquid and prevent the residual liquid from being present. The first end of the drainage portion 150 is connected to the second end of the engagement portion 120, and a step structure is formed therebetween, and the step structure abuts against the second end of the liquid outlet 300, so that liquid residue can be further prevented. The outer side of the reinforcing rib plate 142 is connected to the inner wall of the drainage portion 150, and the second end of the engagement portion 120 is connected through the drainage portion 150. In addition, the inner wall of the supporting part 130 may be separately connected to the outer wall of the engaging part 120 or the second end of the engaging part 120, and may also be connected to the outer wall of the drainage part 150, and the second end of the engaging part 120 is connected through the drainage part 150; of course, the closer the support 130 is to the first end of the engagement portion 120, the more advantageous it is to reduce the height requirement for the docking member 200.
The sealing plug 100 is also provided with a butt joint 160. The abutting portion 160 is configured as a cylindrical structure coaxially disposed with the other portion of the sealing plug 100, and a first end thereof is connected to a second end of the supporting portion 130. The outer wall of the docking portion 160 is configured to be in clearance fit with the inner wall of the fluid inlet 510, so that the docking portion 160 is inserted into the fluid inlet 510, thereby docking the fluid inlet 510, while avoiding resistance to the precession of the fluid inlet 510.
In use, the support 130 divides the internal thread of the docking member 200 into two parts, an i-th part being located between the first end of the docking member 200 and the support 130 and an ii-th part being located between the support 130 and the second end of the docking member 200, as shown in fig. 4. When the sealing part 110 and the liquid outlet nozzle 300 are in the optimal sealing position, the length of the ii-th part internal thread exceeds 1/2 cycle, so as to guide the liquid inlet 510 of the access docking piece 200 to be screwed in later; meanwhile, the height of the internal thread of the i part is greater than that of the internal thread of the ii part, so that the sealing part 110 is pushed to be completely separated from the liquid outlet nozzle 300 and pulled away from the liquid outlet nozzle 300 by a certain distance, a gap for the first liquid to flow out is formed, and preferably, the difference between the height of the internal thread of the first part and the height of the internal thread of the second part is greater than or equal to 3mm. When the liquid inlet 510 is screwed into the supporting part 130, the screwing angle alpha of the external thread of the liquid inlet 510 and the internal thread of the butt joint piece 200 is more than or equal to 90 degrees, that is, after the liquid inlet 510 of the second container 500 is screwed into the butt joint piece 200 for more than or equal to one quarter turn, acting force is applied to the supporting part 130 to open the channel.

The container closure structure of this embodiment is substantially identical to that of the first embodiment, and includes a sealing plug 100 as well for removably closing a first container 400 having a spout 300 and a docking member 200, and which can be opened only upon engagement of a second container 500; the sealing plug 100 also comprises a sealing portion 110, an engagement portion 120 and a supporting portion 130, the main differences being that: the sealing plug 100 is further provided with a screwing part 170.
Referring to fig. 7 to 8, the screwing part 170 is configured as a cylindrical structure coaxially disposed with other parts of the sealing plug 100, and a first end thereof is connected to an outer wall of the supporting part 130. The outer wall of the screwing part 170 is used for being in threaded connection with the inner wall of the butt joint piece 200, 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 170 is in threaded connection with the outer wall of the liquid inlet 510, and after the liquid inlet 510 and the screwing part 170 are screwed in place, continued screwing of the liquid inlet 510 drives the screwing part 170 to screw in the butt joint piece 200, so that the sealing part 110 is pushed to enter the first container 400, and unsealing is achieved. When the liquid inlet 510 is screwed into the supporting part 130, the screwing angle α of the external thread of the liquid inlet 510 and the internal thread of the screwing part 170 is greater than or equal to 90 °, i.e. after the liquid inlet 510 of the second container 500 is screwed into the screwing part 170 for more than or equal to one quarter turn, a force is applied to the supporting part 130 to open the channel.
The surface of the abutment 200 facing the first end of the support 130 and the first end of the support 130 are respectively provided with first non-return structures 012 which are matched with each other, and the first non-return structures 012 may be non-return ratchets. After the sealing plug 100 is driven by the liquid inlet 510 to be screwed in to a certain extent, the first non-return structure 012 on the supporting part 130 and the first non-return structure 012 on the butt joint piece 200 are connected and locked; when the second container 500 is reversely rotated after the first liquid is released, the sealing plug 100 and the butt joint member 200 cannot rotate relatively due to the first check structure 012, and the whole formed by the sealing plug 100 and the butt joint member 200 rotates relatively to the second container 500, so that the second container 500 can be directly detached from the butt joint member 200, and the use difficulty is reduced. If the first container 400 is located opposite the first end of the support 130, the first backstop 012 may be disposed on the support 130 and the first container 400.
In the above two embodiments, the liquid outlet 300 and the docking member 200 may be integrally formed on the first container 400 (fig. 4), or may be detachably or non-detachably mounted on the first container 400 (fig. 10 and 14). If the docking member 200 is removably or non-removably mounted to the first container 400, the docking member 200 may be part of a container closure structure; if the docking member 200 and spout 300 are removably or non-removably attached to the first container 400, the docking member 200 and spout 300 may be part of a container closure. Thus, a third embodiment and a fourth embodiment of the container closure structure will be presented below.
Fig. 9 illustrates a third embodiment of a container closure structure comprising a docking piece 200 and a sealing plug 100. The container closure is used to close a first container 400 without a docking member 200 to form a packaging system for use therewith, as shown in fig. 10; and also for removably interfacing with a second container 500 to form yet another packaging system, as shown in fig. 11; the former packaging system can only be unsealed with the cooperation of the second container 500. The structures of the sealing plug 100 and the second container 500 may be referred to above, and will not be described here.

At least a portion of the outer wall of the first container 400 may be configured as a cylindrical structure coaxial with the spout 300, and external threads may be configured therein.
Referring to fig. 9 to 11, the docking member 200 is configured in a cylindrical structure with a first end for accessing the first container 400 and a second end for sequentially accessing the sealing plug 100 and the second container 500. After the first container 400 is inserted, the liquid outlet 300 is coaxially disposed in the docking member 200. Specifically, the docking member 200 includes an I-th portion proximate the first end and an II-th portion proximate the second end. The inner wall of the I-th portion of the docking member 200 is configured with internal threads for removable connection with external threads on the outer wall of the first container 400. A second non-return structure 024, such as a non-return ratchet, is disposed between the docking member 200 and the first container 400, so that the docking member 200 forms an integral unit with the first container 400 after being mounted in place on the first container 400, thereby realizing non-detachable connection and preventing misoperation. The inner wall of the second part of the abutment 200 is provided with an internal thread for connection with the screwing part 170 of the sealing plug 100; if the sealing plug 100 is not provided with the screwing part 170, it can be used for connection with the liquid inlet 510 of the second container 500.
