[0042] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0043] like Figure 1-Figure 5 As shown, a multi-chamber mixed extrusion tank body includes a tube body assembly and a tube head assembly connected to the tube body assembly;

[0044] The tube body assembly is formed by splicing at least two tube body units 1, each of which has a tube cavity 2, and a mounting channel 5 is formed on the inner side of the plurality of tube body units 1, and an air supply pipe 6 corresponding to the tube body units 1 is arranged in the mounting channel 5, and a piston push plate 3 and an airbag assembly 4 are arranged in the tube cavity 2 of each tube body unit 1, and the airbag assembly 4 is located below the piston push plate 3, and the air supply pipe 6 is connected to the airbag assembly 4 in the corresponding tube body unit 1 through a first one-way valve 13;

[0045] The tube head assembly includes a tube head body 7, a paste outlet nozzle 9 arranged on the tube head body 7, the paste outlet nozzles 9 are respectively connected to the tube cavity 2 of the tube body unit 1, a rubber pressing ball 10 is arranged in the tube head body 7, an air inlet hole is arranged on the rubber pressing ball 10, a second one-way valve is arranged in the air inlet hole, the air outlet of the rubber pressing ball 10 is connected to an air outlet pipeline, and the air outlet pipeline is connected to all the air supply pipes 6 through a regulating valve 12, and the tube head body 7 is also provided with an operation key 14 for controlling the regulating valve 12 to change the gas flow ratio between the air supply pipes 6;

[0046] A pressing piece 11 is also slidably disposed on the tube head assembly, and the top of the rubber pressing ball 10 is in conflict with the pressing piece 11 .

[0047] The principle is that the volume of the rubber pressing ball 10 does not change. Therefore, each time it is pressed, the stroke of the operating pressing member 11 is consistent, so that when the rubber pressing ball 10 is compressed, the amount of gas filled into the air supply pipe 6 is constant, and then the rubber pressing ball 10 recovers itself by elasticity and at the same time, the external gas is sucked into the rubber pressing ball 10 through the first one-way valve 13. At the same time, the recovery of the rubber pressing ball 10 causes the pressing member 11 to reset itself, so that the amount of gas filled into the airbag is constant each time. Since the tube unit 1 is a columnar structure with a consistent cross-sectional size, the moving distance of the piston push plate 3 is consistent, and finally the amount of paste output is constant, so that each time the toothpaste can be quantitatively squeezed out. Finally, since multiple tube units 1 are provided, each tube unit 1 is loaded with toothpastes with different functions, and the regulating valve 12 is operated by operating the operating key 14, thereby achieving It is found that each time the air is inflated, the amount of gas entering different air supply pipes 6 can be adjusted. The air supply pipe 6 with a larger amount of inflation has a larger amount of change in the corresponding air bag, so that the piston push plate 3 rises a larger amount, and thus the amount of paste discharged is larger. Therefore, when using it, consumers can use it flexibly according to the condition of their own teeth. For example, a user who needs long-term teeth whitening can increase the amount of gum protection toothpaste used each time when the gum condition occurs, and then increase the amount of whitening toothpaste used after the gum condition improves. In order to facilitate the user's reference operation, the operation key 14 is a knob that is rotated on the tube head body 7, and the knob is surrounded by a ratio scale of toothpaste paste A and toothpaste paste B. The user only needs to adjust the ratio to be set, and each press can achieve quantitative discharge of the two toothpastes according to the set ratio.

[0048] It should be noted that the above-mentioned can body is not limited to use in toothpaste, but can also be used for packaging of viscous oral care essence, skin care products and other products.

[0049] In this embodiment, there are two tube body units 1 , and toothpaste A and toothpaste B are respectively arranged in the tube cavities 2 of the two tube body units 1 , and the regulating valve 12 is a three-way regulating valve 12 .

[0050] Of course, in addition to this, the tube body unit 1 can also be set to three, that is, whitening toothpaste, gum protection toothpaste and children's toothpaste are respectively set in the tube body unit 1, so that the same toothpaste can meet the needs of a family of three at the same time, and there is no need to purchase multiple types of toothpastes additionally. It can not only manage the oral cavity scientifically but also save living costs.

[0051] Optionally, the tube head body 7 is threadedly connected to the upper part of the tube body unit 1, the paste outlet nozzle 9 is connected to the tube cavity 2 of the tube body unit 1 through a connecting hose, and the connecting hose is plugged into the paste outlet of the tube body unit 1.

[0052] In order to make the airbag sufficient to squeeze out the toothpaste in the lumen 2 completely and avoid waste, the deformation of the airbag needs to be large enough, so the airbag component 4 needs to be optimized, such as Figure 3 As shown, the airbag assembly 4 is in a continuously bent shape. In addition, the airbag assembly 4 can also be in a continuously bent shape. Figure 4 The airbag assembly 4 shown includes a plurality of airbag units connected in sequence.

[0053] In order to enable the rubber pressing ball 10 to communicate with the outside world for inflation, the pressing member 11 is a hollow structure.

[0054] In order to keep the paste dispensing nozzle 9 clean and hygienic, a tube cover 8 matched with the tube body assembly is also included, and the tube cover 8 is arranged above the tube head assembly.

[0055] It should be noted that when this product is purchased and used, it needs to be pressed multiple times for the first time so that each tube unit 1 can discharge the paste. Since the connecting channel between the tube cavity 2 and the paste discharge nozzle 9 is a hollow structure when leaving the factory, it is necessary to press multiple times to fill the connecting channel with the paste before the quantitative and top ratio pressing and discharging of the paste can be achieved.

[0056] In addition, this embodiment also provides a multi-chamber mixed extrusion toothpaste, including a tube body assembly and a tube head assembly connected to the tube body assembly;

[0057] The tube body assembly is formed by splicing two tube body units 1, each of which has a tube cavity 2, and a mounting channel 5 is formed on the inner side of the plurality of tube body units 1, and an air supply pipe 6 corresponding to the tube body units 1 is arranged in the mounting channel 5, and a piston push plate 3 and an airbag assembly 4 are arranged in the tube cavity 2 of each tube body unit 1, and the airbag assembly 4 is located below the piston push plate 3, and the air supply pipe 6 is connected to the airbag assembly 4 in the corresponding tube body unit 1 through a first one-way valve 13;

[0058] The tube head assembly includes a tube head body 7, a paste outlet nozzle 9 arranged on the tube head body 7, the paste outlet nozzles 9 are respectively connected to the tube cavity 2 of the tube body unit 1, a rubber pressing ball 10 is arranged in the tube head body 7, an air inlet hole is arranged on the rubber pressing ball 10, a second one-way valve is arranged in the air inlet hole, the air outlet of the rubber pressing ball 10 is connected to an air outlet pipeline, and the air outlet pipeline is connected to all the air supply pipes 6 through a regulating valve 12, and the tube head body 7 is also provided with an operation key 14 for controlling the regulating valve 12 to change the gas flow ratio between the air supply pipes 6;

[0059] A pressing piece 11 is also slidably provided on the tube head assembly, and the top of the rubber pressing ball 10 is in conflict with the pressing piece 11;

[0060] The two tube units 1 are respectively loaded with a freshening composition toothpaste and a natural gum protection composition toothpaste;

[0061] The refreshing toothpaste composition includes 0.2-2 parts of persimmon fruit extract or emblica extract or shimeji extract, 0.01-0.5 parts of plant enzyme, 0.01-0.5 parts of complex amino acid, 0.5-3 parts of PVM / MA copolymer, 10-25 parts of abrasive, 5-66 parts of moisturizer, 0.1-2 parts of thickener, 0.1-5 parts of sweetener, 1-3 parts of foaming agent, appropriate amount of pH regulator and 0.1-2 parts of stabilizer, 0.5-1.5 parts of fragrance, and the rest is water, wherein persimmon fruit comes from green immature fruit, which is obtained after multiple processes to remove astringency, and is rich in tannins, polyphenols, amino acids, etc. Plant enzymes are natural enzyme preparations. PVM / MA, with a high molecular weight network structure, is a very effective alkaline phosphatase inhibitor, and provides sustained release and long-lasting effects through film formation; the complex amino acid contains arginine, glycine, lysine, and histidine.

[0062] The natural gum protection composition toothpaste comprises, by weight, 0.5-5 parts of gum protection composition, 10-30 parts of abrasive, 20-66 parts of moisturizer, 0.1-2 parts of thickener, 0.1-5 parts of sweetener, 1-3 parts of foaming agent, an appropriate amount of pH regulator and 0.1-2 parts of stabilizer, 0.5-1.5 parts of fragrance, and the rest is water. Preferably, the gum protection composition is at least one of scutellaria baicalensis, magnolia bark extract, chamomile derivative, dipotassium glycyrrhizate, and perilla seed extract, wherein scutellaria baicalensis is derived from the bark or root bark of the ilex plant of the ilex family, which is crushed, ultrasonically extracted, and dried; dipotassium glycyrrhizate and perilla seed extract are both derived from natural plants, and their combined use has significant effects of inhibiting dental plaque, alleviating gingivitis, and promoting the healing of recurrent oral ulcers. The total effective content of Magnolia officinalis extract is more than 98%, and the mass ratio of magnolol to honokiol is 1:1. The test on the dental caries pathogen, namely Streptococcus mutans, shows that it has a high-efficiency and rapid bactericidal effect. Chamomile derivatives are extracted from a plant of chamomile to obtain a derivative of azulene, guaiazulene, on which a sodium sulfonate group is connected to the five-membered ring of this component to produce water-soluble dark blue crystals, namely sodium azulene sulfonate, also known as sodium guaiazulene sulfonate, which is a derivative of sesquiterpenoid azulene compounds.

[0063] Among the above components, the friction agent is one or more of silicon dioxide, calcium hydrogen phosphate, calcium pyrophosphate, light calcium carbonate, natural zeolite, aluminum hydroxide, etc., including but not limited to spherical silica SPHERILEX®145 and ZEODENT®103 (PCR>110) imported from Germany.

[0066] In the above components, the pH adjuster is one or more of trisodium phosphate, tetrasodium pyrophosphate, arginine, tromethamine and citric acid.

[0067] The processes of the two different toothpastes are basically the same, including:

[0068] 1. Dissolve the water-soluble raw materials (sweeteners, stabilizers, pH adjusters) in water and moisturizers. After they are evenly dissolved, pump them into the main pot.

[0069] 2. Disperse the thickener evenly in the abrasive;

[0070] 3. Pump 2 into the main pot, and after the vacuum reaches above -0.096MPa, stir rapidly for 30 minutes;

[0071] 4. Pump the foaming agent, fragrance, and gum protection (freshening) composition into the pot and stir for 15 minutes;

[0072] 5. Discharge the material after it passes the inspection.

[0073] Performance evaluation:

[0074] Stability test

[0075] After standing for 24 hours, the samples were placed in 100 ml transparent plastic bottles and placed at -18°C (1 month), room temperature (25°C) and 50°C for 3 months, respectively, and the appearance and presence of stratification were observed.

[0076] Efficacy evaluation test data

[0077] The antibacterial experiment of fresh toothpaste-related odor-causing bacteria is as follows:

[0078] Test plan:

[0079] Dilute Fn, Pg, and Sm bacteria to appropriate concentrations and spread them on a 96-well plate, 100 μL per well, take 100 μL of positive control, 100 μL of negative control, and sample solution and add them to the 96-well plate, shake gently to mix, put the bacterial culture plate into an anaerobic bag, and culture at 37°C. After the three bacteria were cultured for a fixed time (16 h, 24 h, or 48 h), the OD was detected at 620 nm on a microplate reader.

[0080] Calculation formula:

[0081] Inhibition rate (%) = (1-OD test group / OD negative control group)
