Description

Technical Field

[0001] This invention relates to the field of cosmetic packaging technology, and more specifically to a check seal structure for multi-cavity packaging tubes. Background Technology

[0002] Currently, most multi-chamber tubes on the market use a mother-daughter tube structure. Due to the design, consumers cannot directly see the cosmetic contents inside the tube, and the two contents are not mixed evenly after being squeezed out, affecting the user experience. In addition, the traditional multi-chamber tube design makes it easy for outside air to enter the tube, causing oxidation and deterioration of the contents, failing to provide a good preservation effect and failing to meet user needs. Summary of the Invention

[0003] To solve the above-mentioned technical problems, a check seal structure for multi-cavity packaging tubing is provided.

[0004] To achieve the above objectives, the following solution is provided: a check seal structure for multi-cavity packaging hoses, comprising several loading hoses, and further comprising a connecting module, a discharging module and a check seal valve, wherein the check seal valve is installed in the discharging module, the bottom of the discharging module is installed with a connecting module, and each of the loading hoses is installed at the connecting module; The discharge module includes a mounting base, a connecting sleeve, a discharge nozzle, a plug, and a flow guide cover.

[0012] The following detailed explanation illustrates the specific implementation methods: like Figures 1 to 5 As shown: A check seal structure for multi-cavity packaging hoses includes several loading hoses 1, a connecting module, a discharging module, and a check seal valve 6. The bottom of the discharging module is equipped with the connecting module, which is used to install on the loading hoses 1. The discharging module is used to mix and discharge the contents of each loading hose 1. The check seal valve 6 is installed in the discharging module and is used to isolate the contents of the discharging module and each loading hose 1 from the outside air, reduce the rate of oxidation and deterioration of the contents, and prevent backflow of the contents. The connection module includes a fixed base 2 and several fixed sleeves 21. The fixed base 2 is fixedly installed at the bottom of the mounting base 3. Several fixed sleeves 21 are provided at the fixed base 2. The discharge end of the loading hose 1 can be snapped into the fixed sleeve 21, thereby fixing the loading hose 1 at the bottom of the discharge module. The discharge module includes a mounting base 3, a connecting sleeve 33, a discharge nozzle 36, a plug 5, and a guide cover 4. The connecting sleeve 33 is fixedly mounted on the mounting base 3. The mounting base 3 has several connecting holes 32, which communicate with the fixed sleeve 21, allowing the contents of the loading hose 1 at the fixed sleeve 21 to enter the discharge module through the connecting holes 32. A discharge nozzle 36 is located at the end of the connecting sleeve 33 furthest from the mounting base 3, and is used to finally discharge the mixed contents. Several feed inlets 34 are evenly distributed on the side wall of the connecting sleeve 33, and their positions are adapted to the positions of the connecting holes 32. The guide cover 4 is fitted onto the connecting sleeve 33 and fixedly mounted on the mounting base 3. The guide cover 4 has... Several guide channels 41 are provided, which are adapted to the connecting hole 32 and the feed inlet 34. One end of the guide channel 41 is connected to the connecting hole 32, and the other end of the guide channel 41 is connected to the feed inlet 34. The contents of the loading hose 1 can enter the connecting sleeve 33 from the feed inlet 34 through the guide channel 41 of the guide cover 4. An elastic baffle 35 is provided at the feed inlet 34. One end of the elastic baffle 35 is fixedly connected to the side wall of the connecting sleeve 33. The elastic baffle can relatively block the feed inlet 34, reduce the extrusion flow of the contents in the loading hose 1, and reduce the probability of the contents in the loading hose 1 coming into contact with the outside air. When the loading hose 1 is squeezed, the contents can push the elastic baffle open and then smoothly enter the connecting sleeve 33. The connecting sleeve 33 is equipped with a check valve 6 and a plug 5. The plug 5 is fixedly installed below the feed inlet 34, and the check valve 6 is installed above the feed inlet 34, so that the contents of the loading hose 1 can enter the space of the connecting sleeve 33 between the plug 5 and the check valve 6 for mixing. The check valve 6 includes a valve body and a valve core. The valve core is installed in the valve body, which is installed inside the connecting sleeve 33. The valve body includes a support sleeve 61 and a sealing base plate 62. The sealing base plate 62 is fixedly installed at the bottom of the support sleeve 61 and is integrally formed with the support sleeve 61. A discharge port 63 is provided in the middle of the sealing base plate 62. The valve core includes an integrally formed connecting sleeve 64, several connecting springs 65, and a sealing spring 66. The sealing spring 66 is installed inside the connecting sleeve 64 through the several connecting springs 65. The sealing spring 66 and the connecting sleeve are connected... The inner wall of 64 is separated, and the gap between the connecting spring 65, the connecting sleeve 64, and the sealing spring 66 forms the discharge groove 67. The connecting sleeve 64 is installed in the support sleeve 61, and the sealing spring 66 abuts against the sealing base plate 62, so that the sealing spring 66 closes the discharge port 63. When the contents in the connecting sleeve 33 enter from the discharge port 63, it can push the sealing spring 66, so that the sealing spring 66 separates from the sealing base plate 62, thus opening the discharge port 63. Then the contents enter the valve core and are discharged from the discharge groove 67 to the discharge nozzle 36.

[0013] The outer wall of the fixed base 2 is provided with external threads, so that the matching end cap can be screwed onto the fixed base 2 to wrap around the discharge module and protect it.

[0014] The specific implementation process is as follows: When using the check seal structure for multi-cavity packaging hoses, firstly, each loading hose 1 containing contents is installed into each fixed sleeve 21. When the contents of the loading hose 1 are needed, each loading hose 1 is squeezed, causing the contents to be expelled into the guide groove 41 of the guide cover 4. Through the guide groove 41, the contents are conveyed to the inlet 34 on the side wall of the connecting sleeve 33. Then, under the pressure of the contents, the elastic baffle is pushed, allowing the contents to smoothly enter the connection between the plug 5 and the check seal valve 6. Within the space of the connecting sleeve 33, the contents can be mixed within the connecting sleeve, continuously squeezing the loading hoses 1. The mixed contents push the sealing spring 66 from the outlet 63 at the sealing base plate 62, causing the sealing spring 66 to separate from the sealing base plate 62, thus opening the outlet 63. Under the action of the sealing spring 66 and the connecting springs 65, the mixed contents are mixed again and discharged from the outlet groove 67 formed by the gap between the connecting spring, the connecting groove, and the sealing spring 66 to the outlet 36, and finally discharged to the outside from the outlet 36.

[0015] This check seal structure for multi-cavity packaging hoses fixes each loading hose 1 to the fixing seat 2, and connects the hose to the discharge module. When each loading hose 1 is squeezed, the contents of each loading hose 1 are squeezed out to the discharge module for mixing. The mixed contents then pass through the check seal valve 6 and are discharged to the outside through the discharge nozzle 36. The contents are further mixed when flowing through the check seal valve 6. This check seal structure for multi-cavity packaging hoses allows users to observe the state of the contents inside the loading hose 1, effectively improves the mixing uniformity of the contents of each loading hose 1, and effectively isolates and seals the contents of the loading hose 1, reducing the rate of oxidation and deterioration of the contents and extending the service life of the contents.
