Description

Pump type container for toothpaste and thoothpaste composition}

The present invention relates to a pump-type toothpaste container and a toothpaste composition, and more particularly, to a pump-type toothpaste container having a structure for pumping the toothpaste stored in the container and discharging it through a nozzle, and a toothpaste composition for receiving in the container. .

In general, paste-like toothpaste is put into a tubular soft container and commercialized.This tubular toothpaste container has a problem of pressing the container with a strong force to squeeze the toothpaste due to the high viscosity of the toothpaste, and it is easy to discharge the remaining amount. There was no discomfort.

In toothpaste, sorbitol is mainly used as a humectant and moisturizer. Sorbitol is used in an aqueous solution of about 70%, but it has a property of rapidly converting to a solid as water dries. In particular, since toothpaste contains a solid content as an abrasive, it can be easily solidified upon contact with air. In view of this problem, in recent years, attempts have been made to promote the convenience of consumers by applying a deep tube pump type container widely used for shampoo or body wash to toothpaste.

This deep tube pump type container has the advantage of being easy to introduce due to its excellent versatility and low unit cost, but after final use, the remaining content is excessive and external air can be freely introduced into the container through a nozzle. In the case of use as a container, as the use time increases, the viscosity of the toothpaste increases as the toothpaste dries, so a large force is gradually required for dispensing, and the toothpaste hardens and may not be smoothly discharged.If the toothpaste hardens, the abrasive contained in the toothpaste There was a problem of solidification and abrasion of the piston or nozzle of the pump.

On the other hand, in order to use a deep tube pump type container, toothpaste must flow down to the bottom of the pump by its own weight or gravity within the container. However, since the toothpaste of a high elasticity formulation flows down relatively slowly, there is a problem that the residual amount of toothpaste in the container is excessive. Japanese Patent Laid-Open Publication No. 2009-215176 proposed a delamination toothpaste container including an outer layer forming an exterior and an inner layer accommodating the contents as an alternative, but the volume of the inner layer containing the toothpaste when discharging the actual toothpaste As this contraction occurred, a constriction phenomenon in which the contracted inner layer blocks the entrance of the container occurred, causing a problem in that a significant amount of stored toothpaste could not communicate with the pump dispenser and remained.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view of a pump-type toothpaste container according to a first embodiment of the present invention.

Referring to FIG. 1, the pump-type toothpaste container 1 according to the first embodiment of the present invention includes a container body 10, a nozzle 20, an airless pump 30, and a tube 40.

The container body 10 includes an outer layer 11 and an inner layer 12, and may include a storage space therein to accommodate the toothpaste (P). Specifically, the outer layer 11 forms the exterior of the container and may have a vent 16, the inner layer 12 is accommodated to be peelable inside the outer layer 11, toothpaste (P) A storage space may be provided inside to accommodate. That is, the container body 10 may be a delamination container.

The container 1 may be vertically erected on the ground, and for this purpose, the container body 10 may have a flat structure in which a part or all of the surface in contact with the ground may be erected vertically on the ground. In the state where the container 1 contains all of the container body 10, the nozzle 20, the airless pump 30, the tube 40, and the toothpaste P accommodated in the container, in particular, the capacity of the toothpaste P in the container Regardless of the shape and size of the container body 10 as long as it can be vertically erected on the ground, the shape and size of the container body 10 may be, for example, a cylinder, a cone, an elliptical column, a rectangular parallelepiped or It can be a prism. Preferably, the container body 10 may have a conical shape, and more preferably, in consideration of the center of gravity of the container body 10, at least a portion of the body may be in the form of a light beam.

The container body 10 may be manufactured through multi-layer blow molding of a thermoplastic resin. Multilayer blow molding is a molding method in which a thermoplastic resin is injected into a mold of a pre-prepared shape and then stretched into the mold by controlling the temperature. Two or more different types of thermoplastic resins may be used, and at the same time or A multilayer structure of the outer layer 11 and the inner layer 12 may be formed by sequentially blowing heat into the resins to form a multilayer. In multilayer blow molding, the resin and the air injection part may be molded in the shape of the container inlet 13. That is, the outer layer 11 and the inner layer 12 may form the container inlet 13 in a bonded state, and may be peeled off from the rest of the container inlet 13 other than the container inlet 13. Accordingly, through the container inlet 13, it communicates with the storage space of the inner layer 12, and may not communicate with the inside of the outer layer 11. The container inlet 13 may be used for injection and discharge of the toothpaste P, and the container body 10 may be used to engage the cap 14. The toothpaste (P) may be stored inside the container body 10 only through the container inlet 13 and may be discharged to the outside, and the cross section of the container inlet 13 may be circular.

The outer layer 11 forms the exterior of the container 1 and may have a vent 16. The outer layer 11 may be made of at least one selected from the group consisting of polypropylene, high-density polyethylene, polycarbonate, and polyethylene terephthalate, and may have a hardness sufficient to allow the container 1 to be vertically erected on the ground. Preferably, the outer layer 11 may have a relatively higher hardness than the inner layer 12. In addition, the outer layer 11 may be opaque and may not transmit part or all of the shape of the inner layer 12. Through this, it is possible to prevent a change in the quality of the toothpaste due to external UV transmission, and to conceal the deformation of the inner layer 12 to be described later from the outside, thereby improving aesthetics in appearance.

The vent 16 is formed on one surface of the outer layer 11, preferably on the bottom surface of the container 1 in contact with the ground, so that air can communicate with the inside and outside of the outer layer 11. When discharging the toothpaste (P) inside the inner layer (12) storage space through the airless pump (30) to be described later, outside air is introduced into the space between the outer layer (11) and the inner layer (12) through the ventilation unit (16). As it can be injected, smooth discharge operation and stable discharge of toothpaste can be achieved without contacting the toothpaste P accommodated in the storage space inside the inner layer 12 with external air. More specifically, if the vent 16 is formed only on the outer layer 11 so as to inject external air into the space between the outer layer 11 and the inner layer 12 through the outer layer 11, the shape and size and The number may not be limited. Preferably, the vent 16 may be formed in a slit shape on the outer layer 11 through a pinch off process during multilayer blow molding of the container body 10. The pinch-off process cuts the overlapping portion of the outer layer 11 at the lower portion where the outer layer 11 and the inner layer 12 are pinched together during multilayer blow molding, thereby sliting the ventilation portion 16 at the lower portion of the outer layer 11. It may be formed in a shape.

The bottom surface of the outer layer 11 of the container 1 in contact with the ground can be divided into an area in which the ventilation unit 16 is formed and the remaining area, and the remaining area in which the ventilation unit 16 is not formed is a protrusion (not shown). ), it is possible to smoothly inject external air through the ventilation unit 16. The protrusion may separate the bottom surface of the container 1 from the ground so that external air is smoothly injected into the space between the outer layer 11 and the inner layer 12 through the ventilation unit 16. In particular, by separating a region in which the ventilation unit 16 is formed from the ground, external air can be smoothly injected through the ventilation unit 16 even when water is accumulated on the ground. In addition, one area in which the ventilation unit 16 is formed is formed to be concave toward the inside of the container 1 compared to the other areas in which the ventilation unit 16 is not formed, so that the ventilation unit 16 is spaced apart from the ground and External air may be smoothly injected into the space between the outer layer 11 and the inner layer 12 through the base 16.

The inner layer 12 is accommodated in the outer layer 11 so as to be peelable, and a storage space may be provided therein to accommodate the toothpaste P. The inner layer 12 may be a separate layer formed to be distinguished from the outer layer 11 according to the multilayer blow molding of the container body 10. The inner layer 12 may form the container inlet 13 in a state of being combined with the outer layer 11, and may be peeled off from the remaining portion other than the container inlet 13.

Referring to FIGS. 3 and 4, the inner layer 12 may be reduced in volume according to the capacity of the toothpaste P received, including a storage space therein. That is, part or all of the inner layer 12 may contact the inner wall of the outer layer 11 according to the amount of toothpaste P accommodated in the storage space, and the inner layer 12 may be As the volume decreases, a part of the inner layer 12 may be peeled off from the inner wall of the outer layer 11. Accordingly, the inner layer 12 may be made of a material capable of changing the volume according to the capacity of the toothpaste P accommodated in the storage space. Preferably, the inner layer 12 has a lower hardness than the outer layer 11, so that a change in volume can easily occur compared to the outer layer 11. For example, the inner layer 12 may be made of one or more selected from the group consisting of ethylene vinyl alcohol, low density polyethylene, and nylon.

The inner layer 12 can be combined with the cap 14 and the airless pump 30 through the container inlet 13, and stores the toothpaste P into the storage space inside through the container inlet 13, and the tube It only discharges through the inlet of, and does not have a separate ventilation part. Accordingly, the toothpaste P accommodated in the storage space of the inner layer 12 may be stored and discharged without contacting external air, and thus the toothpaste P may be stored in a non-drying state. In addition, long-term discharge stability can be secured by preventing abrasion inside the nozzle 20 and the airless pump 30 due to the solidification of the abrasive in the toothpaste P, which may occur when the toothpaste P is dried.

The pumping pressure of the airless pump 30 may be 1.5 to 4.0kgf. The pumping pressure may be the same as an external force required to press the nozzle 20 connected to the airless pump 30 in a vertical lower direction. As described below, the viscosity of the toothpaste that can be used in the pump-type toothpaste container according to an embodiment of the present invention may be 10,000 to 70,000 cP, and the minimum pumping pressure required to pump the toothpaste of this viscosity may be 1.5 kgf. By using the container body 10 including the outer layer 11 and the inner layer 12, the maximum pumping pressure required for pumping toothpaste may be 4.0 kgf. In addition, by using the container body 10 including the outer layer 11 and the inner layer 12, the pumping pressure is increased even when the remaining amount of toothpaste (P) contained in the container 1 decreases according to the discharge and use of toothpaste. It can be kept within range.

One pumping amount of the airless pump 30 may be 0.5 to 3.5g. The pumping amount may be the same as the amount of toothpaste discharged through the discharge port 21 as the nozzle 20 is pressed all the way in the vertical lower direction with an external force.

The airless pump 30 may be coupled to the tube 40 through the lower end of the housing 31 forming the exterior of the pump. Referring to FIG. 1, the tube 40 may be inserted and fixed through the lower end of the housing 31. The outer wall of the tube 40 may be inserted and fixed between the inner wall of the lower end of the housing 31. Although not shown, the tube 40 is inserted to the lower end of the valve provided inside the housing 31 and is in close contact, so that the toothpaste P can be supplied to the airless pump 30 only through the tube 40.

The tube 40 is located inside the storage space in the inner layer 12 and communicates with the airless pump 30 to communicate toothpaste. Specifically, one end of the tube 40 is located inside the storage space and can contact the toothpaste P accommodated in the storage space, and the other end is connected to the discharge path of the airless pump 30 to provide a storage space. It is possible to communicate the toothpaste (P) accommodated in the airless pump (30). More specifically, the remaining end of the tube 40 may be inserted into the housing 31 of the airless pump 30 and fixed.

In the case of the pump-type toothpaste container according to the first embodiment of the present invention, by placing the tube 40 as described above, the volume of the inner layer 12 decreases according to the discharge and use of the toothpaste P, so that the inner layer 12 is Even in the case of contraction, the amount of toothpaste P pumped through the airless pump 30 can be kept constant by securing at least a space equal to or larger than the cross-sectional area of the tube 40 at the container inlet 13. Therefore, the material of the tube 40 is harder than the inner layer 12, so that the shape of the tube 40 should be maintained even under pressure due to the contraction of the inner layer 12 and the toothpaste P must be communicated. For example, the tube 40 may be made of one or more selected from the group consisting of polypropylene, high density polyethylene, polycarbonate, and polyethylene terephthalate, but is not limited thereto. The cross section of the tube 40 may be circular, but is not limited thereto.

The length of the tube 40 may be 1/5 to 4/5 of the depth direction length of the inner layer 12 storage space. That is, by using the fact that the volume of the inner layer 12 is reduced according to the discharge of the toothpaste, one end of the tube 40 can be prevented from touching the bottom of the inner layer 12 storage space. As will be described later, the viscosity of the toothpaste that can be used in the pump-type toothpaste container according to an embodiment of the present invention may be 10,000 to 70,000 cP, and the tube 40 required to pump the toothpaste of this viscosity without stenosis of the inner layer The minimum length may be 1/10 of the length in the depth direction of the storage space. Using the fact that the volume of the inner layer 12 is reduced according to the discharge of the toothpaste, the length of the tube 40 may not exceed 9/10. By using the tube 40 having a length that satisfies the above range, it is possible to prevent the constriction of the container inlet 13 due to the contraction of the inner layer 12, and maintain the pumping pressure and one pumping amount satisfying the above range. I can. Preferably, the length of the tube 40 may be 1/10 to 9/10 of the depth direction length of the inner layer 12 storage space.

The width of the tube 40 may be 3 to 7 mm for a toothpaste composition having a low viscosity of 10,000 to 25,000 cP, and 5 to 9 mm for a toothpaste composition having a high viscosity of 25,000 cP or more. The thickness of the tube 40 may be 0.5 to 1.5 mm.

As described above, in the first embodiment, in the delamination-type pump-type toothpaste container 1 provided with the airless pump 30, the tube 40 is inserted into the lower end of the housing 31 and fixed, so that the toothpaste (P) Even if used by discharging, it is possible to achieve a stable discharge of the toothpaste (P) by preventing the constriction of the container inlet 13 due to the reduction in the volume of the inner layer 12.

One or more adsorption prevention ribs may be provided on the outer wall of the housing 31, and may be provided between one or more suction ports 35. Alternatively, a plurality of adsorption-preventing ribs may be formed on one suction port 35 and may not seal the suction port 35. For example, the adsorption prevention rib is disposed vertically on the suction port 35 to ensure the separation between the suction port 35 and the inner layer 12 even when the inner layer 12 is constricted to each other, thereby providing the suction port 35 You can smoothly inhale toothpaste (P) through.

Hereinafter, an embodiment of a high viscosity toothpaste composition for use in a pump-type toothpaste container according to an embodiment of the present invention will be described. The toothpaste composition according to the present embodiment has a viscosity of 25,000 to 70,000 cP, and is difficult to use in a conventional dip tube pump type container, but is suitable for a pump type toothpaste container according to the present invention.

The toothpaste composition according to an embodiment of the present invention may include water, a thickener, an abrasive, and a polyol. In addition, the toothpaste composition may further include a solubilizing agent, a flavoring agent, a sweetening agent, a medicinal agent, a pH adjusting agent, a preservative, a binder, a foaming agent, and the like, depending on the purpose of use.

Water may be water used in toothpaste compositions in the art. For example, it may be one or more selected from the group consisting of purified water, aloe vera extract, witch hazel extract, cucumber extract, lemon extract, and lavender extract, but is not limited thereto.

Water may be included in 25 to 50% by weight based on 100% by weight of the toothpaste composition. If water is contained in an amount of less than 25% by weight, the loosening property of the toothpaste in the oral cavity is significantly lowered, and the phenomenon of lumps sagging when the composition is discharged becomes severe. Significantly lowered.

The thickener may adjust the viscosity of the toothpaste composition to 25,000 to 70,000 cP, which is a viscosity suitable for loading and discharging in the pump-type toothpaste container of the present invention. Thickeners can be organic or inorganic binders. As the organic thickener, at least one organic polymer selected from xanthan gum, cellulose gum, gum arabic, locust bean gum, alginic acid, and alginate may be used. As the inorganic thickener, silica for thickening, bentonite, etc. may be used, but silica for thickening may be preferably used.

Increasing silica may include precipitated silica or colloidal silicon dioxide, and may mean that the BET specific surface area is 500 m ² /g or more. Precipitated silica is prepared by mixing sand and caustic soda, dissolving in water, performing a sol-gel reaction, and then adding sulfuric acid, and adjusting the sol-gel reaction time and conditions to obtain a BET specific surface area of 500 m ² /g or more. It can be prepared with silica for increasing the amount. Colloidal silicon dioxide can be produced by spraying silicon tetrachloride and burning it. Increasing silica has a higher specific surface area than polishing silica, so it can absorb more water, thereby increasing the viscosity over time of the composition. In addition, the silanol group (-SiOH) contained in the incremental silica can strongly interact with the adjacent silanol group through hydrogen bonds, thereby increasing the elasticity of the toothpaste to improve shape retention. Increasing silica may be included in an amount of 0.1 to 8.0% by weight based on 100% by weight of the toothpaste composition. If less than 0.1% by weight of silica for incremental is added, it will not be possible to improve the shape retention of toothpaste, and if it is used in excess of 8% by weight, the shape retention will be improved, but the discharge pressure will increase due to excessive increase in viscosity to prevent discharge. do.

The solubilizing agent is capable of solubilizing a material having low solubility in water, and may be used in a toothpaste composition in the art. For example, polyglyceryl-3 methylglucose distearate, oles-10, oles-10/polyoxyl 10 oleyl ester NF, ceres-10, PEG-8 laurate, cocamite MEA, polysorbate 60 NF, polysorbate 60, polysorbate 80, isosteareth-20, polysorbate 80 NF, PEG-20 methylglucose sesquistearate, ceteareth-20, oleth-20, steareth-20, Steareth-21, Ceres-20, poloxamer 184, and may be one or more selected from the group consisting of poloxamer 407, but is not limited thereto.

The abrasive has a function of removing plaque from the oral cavity, and may be used in a toothpaste composition in the art. For example, it may be at least one selected from the group consisting of hydrated silicon dioxide, silicon dioxide, precipitated silica, calcium carbonate, polyethylene, cellulose, and zeolite, but is not limited thereto. The abrasive may be contained in an amount of 5% to 18% by weight based on 100% by weight of toothpaste. If the abrasive is less than 5% by weight, the organic binder may cause a feeling of slippery when brushing, and the feeling of good luck may be lowered.If it is used in excess of 18% by weight, the piston of the pump is worn, resulting in a decrease in the life of the pump and lowering the discharge stability. .

The polyol can prevent abrasion of the nozzle and pump due to the abrasive in the toothpaste composition, and prevent hardening at the discharge port in contact with the air in the toothpaste container. Polyols may be those used in toothpaste compositions in the art. For example, it may be one or more selected from the group consisting of ethylene glycol, polyethylene glycol, propylene glycol, polypropylene glycol, and glycerin, but is not limited thereto. The polyol may include at least one of a liquid and a solid polyol, and sorbitol may be used as a solid polyol. The polyol may be contained in an amount of 2% to 70% by weight based on 100% by weight of toothpaste. The toothpaste composition according to the present embodiment may be used by mixing a liquid polyol and sorbitol, and a solid sorbitol may be mixed in the form of an aqueous solution. The ratio of sorbitol (70% aqueous solution) and polyol may be 1:0.1 to 1:4. In this way, when liquid and solid polyols are mixed and used, the liquid polyol is hydrolyzed to the solid polyol, thereby minimizing evaporation of water in the mixture, and even if water evaporates, it is possible to prevent the formation of a strong network between the polyols. Therefore, when the solid polyol is used alone, it is possible to solve the problem of hardening of the discharge port where air contacts in the toothpaste container.

Flavoring agents remain in the oral cavity and continuously emit scent, and any one or more selected from the group consisting of mint such as peppermint and spearmint, eugenol, methyl salicylate, winter green extract, melon extract, strawberry extract and orange extract However, it is not limited thereto.

Sweeteners are added to overcome the taste of the toothpaste composition, and any one or more selected from the group consisting of saccharin, sucralose, sugar, xylitol, lactose, mannitol, maltitol, erythritol, aspartame, and taurine, or their pharmaceutically It may be an acceptable salt, but is not limited thereto.

Medicinal agents can be added for oral hygiene, and ingredients that have effects such as tooth decay prevention, recalcification, gum disease prevention, tartar deposition prevention, and whitening can be used. Compounds capable of supplying fluorine ions, such as sodium fluoride, sodium monofluorophosphate, and tin fluoride, can be used as a drug used for the purpose of preventing tooth decay. Remineralizing agents can also act as tooth decay prevention. Remineralization regenerates and restores hydroxyapatite, which is a major component of teeth.Calcium ions and phosphate ions are supplied at the same time, or calcium divalent cations or phosphoric acid are used to move the chemical equilibrium in the oral cavity toward the formation of hydroxyapatite. Those containing anions can be used. For example, hydroxyapatite, dicalcium phosphate, calcium chloride, casein phospheptide, calcium glycerophosphate, sodium phosphate, sodium phosphate, sodium phosphate, potassium phosphate, potassium phosphate and potassium 3 It may be one or more selected from the group consisting of potassium phosphate. As a medicinal agent for preventing gum disease, isopropylmethylphenol, cyclohexidine, cetylpyridinium chloride, triclosan, xantorazole, etc., which can sterilize harmful microorganisms in the oral cavity, can be used, and for anti-inflammatory properties of the gums. Vitamins and enzymes, aminocaproic acid, and allatoin can be used. Medicinal agents used for the purpose of preventing tartar deposits include sodium pyrophosphate, acid sodium pyrophosphate, potassium pyrophosphate, and sodium metaphosphate, and hydrogen peroxide, carbamide peroxide, calcium peroxide, etc. have.

The pH of the toothpaste composition is preferably 5 to 8, and the pH adjuster may be phosphoric acid, sodium phosphate, citric acid, sodium citrate, succinic acid, sodium succinate, tartaric acid, sodium stannate, or the like.

The preservative may be one or more selected from the group consisting of benzoic acid, methylparaben, propylparaben, and sodium benzoate.

Foaming agents may be added to facilitate foaming when using the toothpaste composition. For example, sodium laurate, sodium palmitate, sodium lauryl sulfate, potassium lauryl sulfate, triethanolamine POE-lauryl sulfate, sodium POE-lauryl sulfate, sodium lauroyl sarcosine, N-myristoyl- Anionic surfactants such as sodium N-methyltaurine; Stearyltrimethylammonium chloride, lauryltrimethylammonium chloride, cetylpyridinium chloride, N,N'-dimethyl-3,5-methylenepiperidinium, alkyl quaternary ammonium salt, alkyldimethylbenzylammonium salt, alkylisoquinolinium salt, di Cationic surfactants such as alkyl morphonium salts, benzalkonium chloride and benzethonium chloride; 2-undecyl-N,N,N-(hydroxyethylcarboxymethyl)-2-imidazoline sodium, 2-cocoyl-2-imidazolinium hydroxide-1-carboxyethyloxydisodium salt, Amphoteric surfactants such as 2-heptadecyl-N-carboxymethyl-N-hydroxyethylimidazolinium betaine, lauryldimethylamino acetic acid betaine, alkyl betaine, amide betaine and sulfo betaine; And sorbitan monooleate, sorbitan monoisostearate, sorbitan monolaurate, sorbitan monopalmitate, sorbitan monostearate, sorbitan sesquioleate, sorbitan trioleate, penta-2-ethyl Hexyl diglycerol sorbitan, tetra-2-ethylhexyl diglycerol sorbitan, mono cottonseed oil fatty acid glycerin, monoerucic acid glycerin, sesquioleic acid glycerin, monostearic acid glycerin, α,α'-oleic acid pyroglutamic acid glycerin, monostearic acid Glycerin malic acid, POE-sorbitan monooleate, POE-sorbitan monostearate, POE-sorbitan tetraoleate, POE-sorbit monolaurate, POE-sorbit monooleate, POE-sorbitpentaoleate , POE-nonionic surfactants such as sorbit monostearate; any one or more selected from the group consisting of may be used.

Additionally, the toothpaste composition according to the present embodiment may further include polyacrylic acid or a pharmaceutically acceptable salt thereof. Polyacrylic acid is a -COOH functional groups in a condition that the pH value of 4 to 10 -COO ^- a polymer, which may have an elasticity to put into lead to electrostatic repulsion. Polyacrylic acid has very high elasticity compared to polymers commonly used in toothpaste such as cellulose gum and xanthan gum. Accordingly, the toothpaste further comprising polyacrylic acid or a pharmaceutically acceptable salt thereof may have elasticity as well as viscosity. The toothpaste composition further containing polyacrylic acid or a pharmaceutically acceptable salt thereof may improve the shape of the toothpaste, but at low viscosity, the flowability decreases and the remaining amount increases, so its use is limited in the deep pump container, and the above implementation It can be applied to a pump-type toothpaste container such as an example to provide improved shape retention.

Polyacrylic acid or a pharmaceutically acceptable salt thereof may be included in an amount of 0.2% to 1.5% by weight based on 100% by weight of the composition. If polyacrylic acid or a pharmaceutically acceptable salt thereof is used in an amount less than 0.2% by weight, toothpaste does not improve the shape retention, and if it is used in more than 1.5% by weight, the viscosity increases as well as elasticity to increase the discharge pressure to lower the discharge stability. do.

When the toothpaste composition according to the present embodiment is loaded in a pump-type toothpaste container and pumped once and discharged, the lump height after 5 seconds of discharge may be 0.7 to 0.95 of the discharge port diameter of the pump-type toothpaste container.

Experimental Example 1. Viscosity of toothpaste composition

The toothpaste composition prepared in Preparation Example and Comparative Example was measured at 25°C with a Brookfield viscometer RVT type after 5 rotations at 20 rpm using spindles 5 to 7 and then the initial viscosity value (cP). After the toothpaste composition was sealed and stored for 1 month, the viscosity value (cP) over time was measured by the same method, and the results are shown in Table 3 below.

The toothpaste composition according to the present preparation example achieved a high viscosity of 25,000 cP or more based on the initial viscosity including silica for increasing. In Comparative Examples 1 and 4 in which the incremental silica was not used, a sufficient initial viscosity was not secured, and in Comparative Example 3, which used an excessive amount of incremental silica compared to this Preparation Example, the viscosity over time reached 100,000 cP after 1 month, and the pump was operated. It became difficult to dispense toothpaste.

Experimental Example 2. Discharge and remaining amount per container

The toothpaste composition prepared in Preparation Examples and Comparative Examples was filled in a pump-type toothpaste container (delamination container) according to Example 2 of the present invention and a dip pump toothpaste container including a structure in which a dip tube is connected to a conventional air pump, and the texture analyzer ( TA instrument) was discharged at a rate of once per minute, and discharged until no more discharge was performed to evaluate the discharge properties, and the results are shown in Table 4 below.

As for the dispensing, the remaining amount after discharging was evaluated based on 30% of the total filling amount, and if it was more than 30%, it was evaluated that the corresponding toothpaste composition was not discharged from the container. If the remaining amount exceeded 50%, the measurement of the remaining amount was evaluated as insignificant. (Discharge ○: The remaining amount after discharge is less than 30%, ×: The remaining amount after discharge is more than 30%)

As shown in Tables 4 and 5, the toothpaste composition according to the present preparation example exhibited excellent discharging properties in the delamination container according to Example 2 of the present invention at the beginning and after 1 month, and showed a residual amount of 8% or less. . The toothpaste composition having a content ratio of sorbitol and polyol according to Preparation Examples 11 to 16 was also excellent in discharging properties in the delamination container, and showed a residual amount of 6% or less.

In Comparative Example 2, the polishing silica was used instead of the incremental silica, and the viscosity result showed that discharge was possible, but the discharge stability was poor due to the wear of the piston. In Comparative Example 3, the increase in viscosity over time was too large due to the use of an excessive amount of silica, so that it was impossible to discharge with an airless pump, and a large discharge pressure of 4 kgf or more was required even when discharging the contents at the discharge port.

Experimental Example 3. Shape retention after discharging toothpaste composition

The toothpaste compositions prepared in Preparation Examples and Comparative Examples were filled in a pump-type toothpaste container according to Example 2 of the present invention, and then pumped once to discharge them in a lump form on a plastic plate marked with a scale.

After 5 seconds of discharge, the height of the lump was measured and expressed as a ratio (height/diameter) to the diameter of the discharge port of the pump-type toothpaste container to evaluate the shape retention of the discharged toothpaste lump. If the shape retention is 0.70 or more, the shape does not collapse even if it is discharged to the toothbrush, or it does not soak into the bristles, so a case of 0.70 or more can be evaluated as good.

It was found that the toothpaste composition of the present Preparation Example and Comparative Example 3 including the incremental silica had excellent shape retention. The toothpaste compositions according to Comparative Examples 1, 2, and 4 exhibit shape retention such as flowing down when discharged to a toothbrush and used. Comparative Example 3 was shown to have good shape retention, but it was not discharged due to a large increase in viscosity, and exhibited a high discharge pressure of 4 kgf or more, making it unsuitable for use in pump toothpaste.

Experimental Example 4. Discharge stability by drying the discharge port after discharging the toothpaste composition

After filling the toothpaste composition prepared in Preparation Example and Comparative Example into the pump-type toothpaste container according to Example 2 of the present invention, it was pumped once and discharged. After leaving the toothpaste composition in the discharge port of the container for 1 month at room temperature, it was pumped once again to measure the discharge pressure and check whether the discharge port is clogged to evaluate the discharge stability (discharge pressure evaluation ○: less than 4kgf). , ×: 4kgf or more or the outlet is blocked)

stability ○ ○ ○ ○ ○ ○ ×

With the composition according to Preparation Examples 11 to 16, the toothpaste composition using liquid and solid polyols or only liquid polyols was discharged without clogging the container outlet. In the toothpaste composition according to Comparative Example 5, it was observed with the naked eye that the container discharge port was blocked, and the discharge pressure was also 4kgf or more, which was evaluated as having no discharge stability.
