Description

The present invention relates to a pump-type toothpaste container and a toothpaste composition, and more specifically, the toothpaste stored in the container is pumped and stored in the pump-type toothpaste container having a structure to be discharged through a nozzle and the above-mentioned container. Toothpaste composition for.

Generally, paste-like toothpaste is stored in a tube-type soft container and commercialized. However, due to the high viscosity of toothpaste, the tube-type toothpaste may be pressed with a strong force to squeeze the toothpaste. There was a problem that it had to be done, and there was an inconvenience that it was not easy to discharge the remaining amount.

Sorbitol is mainly used as a moisturizer and a moisturizer for toothpaste. Sorbitol is used in a state of about 70% aqueous solution, but has the property of rapidly changing to a solid when water is dried. In particular, since toothpaste contains a solid content as an abrasive, it can be easily solidified when it comes into contact with air. In consideration of these problems, recently, deep tube pump type containers widely used for shampoo and body wash have been applied to toothpaste for the convenience of consumers.

Such a deep tube pump type container has the advantage that it is easy to introduce because it has excellent versatility and the unit price is low, but after the final use, the remaining amount of the contents is excessively generated, and the external air passes through the nozzle. Because it has a structure that allows it to freely flow into the container, when used as a toothpaste container, the toothpaste dries and becomes more viscous as the usage time increases, and a greater force is gradually required to discharge the toothpaste, making the toothpaste harder. If the toothpaste hardens, the abrasive contained in the toothpaste solidifies and wears the piston and nozzle of the pump.

On the other hand, in order to use the deep tube pump type container, the toothpaste must flow down to the lower end of the pump by its own weight or gravity in the container. However, the highly elastic dosage form of toothpaste has a problem that it flows down relatively slowly and the remaining amount of toothpaste in the container is excessively generated. Japanese Patent Application Laid-Open No. 2009-215176 presents a delamination toothpaste container including an outer layer forming an appearance and an inner layer containing contents as an alternative, but in fact, when the toothpaste is discharged, the toothpaste is used. A constriction phenomenon occurred in which the contracted inner layer blocked the entrance of the container while the volume of the inner layer to be housed contracted, and a considerable amount of the housed toothpaste was not communicated with the pump dispenser and remained.

It can refer to a viscosity of 25,000 cP or higher, preferably in the range of 25,000 to 70,000 cP.

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

FIG. 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 inside so as to accommodate the toothpaste P. Specifically, the outer layer 11 may form the appearance of the container and may have a venting portion 16, and the inner layer 12 is detachably housed inside the outer layer 11 and is inside to accommodate the toothpaste P. May be provided with a storage space. That is, the container body 10 may be a delamination container.

The container 1 may be erected perpendicularly to the ground, and for this purpose, the container body 10 may have a structure in which a part or the whole of a surface in contact with the ground is flat so as to be erected perpendicularly to the ground. Since the container 1 includes the container body 10, the nozzle 20, the airless pump 30, the tube 40, and the toothpaste P housed inside, the container 1 can be erected vertically to the ground regardless of the capacity of the toothpaste P in the container. If there is, the shape and size of the container body 10 are not limited, and the shape of the container body 10 may be, for example, a cylinder, a cone, an elliptical column, a rectangular parallelepiped, or a polygonal column. Preferably, the container body 10 has a conical shape, and more preferably, in consideration of the center of gravity of the container body 10, at least a part of the main body can have an upper narrow and lower wide shape.

The container body 10 may be manufactured by multi-layer blow molding of a thermoplastic resin. Multi-layer blow molding is a molding method in which a thermoplastic resin is injected into a mold (mold) having a shape prepared in advance, and the temperature is adjusted to stretch the shape of the mold. The two different thermoplastic resins are used. The above may be used, and a multilayer structure of the outer layer 11 and the inner layer 12 can be formed by simultaneously or sequentially blowing hot air into the resin to form the resin in multiple layers. During multi-layer blow molding, the resin and air injection parts can be molded into the shape of the container inlet 13. That is, the outer layer 11 and the inner layer 12 can form the inlet 13 of the container in a state of being connected to each other, and can be peeled off at the remaining portion other than the inlet 13 of the container. Therefore, it is possible to communicate with the storage space of the inner layer 12 through the inlet 13 of the container and not to communicate with the inside of the outer layer 11. The inlet 13 of the container may be used for injecting and discharging the toothpaste P, and the container body 10 may be used for binding to the cap 14. The toothpaste P can be stored inside the container body 10 and discharged to the outside only through the inlet 13 of the container, and the cross section of the inlet 13 of the container may be circular.

The outer layer 11 may form the appearance of the container 1 and may have a vent 16. The outer layer 11 may consist of one or more 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 stand vertically on the ground. Preferably, the outer layer 11 may have a relatively higher hardness than the inner layer 12. Further, the outer layer 11 is opaque and does not have to pass through a part or all of the shape of the inner layer 12. As a result, it is possible to prevent a change in the quality of the toothpaste due to the transmission of external ultraviolet rays, and to conceal the deformation of the inner layer 12 described later on the outside to improve the aesthetic appearance.

The ventilation portion 16 is formed on one surface of the outer layer 11, preferably on the bottom surface where the container 1 is in contact with the ground, and allows air to communicate with the inside and outside of the outer layer 11. When the toothpaste P inside the storage space of the inner layer 12 is discharged through the airless pump 30 described later, the outside air can be injected into the space between the outer layer 11 and the inner layer 12 through the ventilation portion 16, so that the inside of the inner layer 12 is inside. Smooth discharge operation and stable discharge of toothpaste can be achieved without bringing the toothpaste P housed in the storage space into contact with the outside air. More specifically, if the ventilation portion 16 is formed only in the outer layer 11 so that the outside air can be injected into the space between the outer layer 11 and the inner layer 12 via the outer layer 11, the shape and size thereof. And the number is not limited. Preferably, the ventilation portion 16 may be formed in a slit shape in the outer layer 11 through a pinch off step during the multilayer blow molding of the container body 10. In the pinch-off step, a ventilation portion 16 is formed in a slit shape at the lower end portion of the outer layer 11 by cutting the portion where the outer layer 11 overlaps at the lower end portion where the outer layer 11 and the inner layer 12 are sandwiched together during the multilayer blow molding. It may be something to do.

The bottom surface of the container 1 in which the outer layer 11 is in contact with the ground can be divided into one region in which the ventilation portion 16 is formed and the remaining region, and the remaining region in which the ventilation portion 16 is not formed is a protrusion (non-projection portion). (Fig.) Can be provided to facilitate the injection of external air through the ventilation section 16. By separating the bottom surface of the container 1 from the ground, the protrusions can allow external air to be smoothly injected into the space between the outer layer 11 and the inner layer 12 via the ventilation portion 16. In particular, by separating one region where the ventilation portion 16 is formed from the ground, it is possible to smoothly inject external air through the ventilation portion 16 even when water is accumulated on the ground. Further, one region where the ventilation portion 16 is formed is formed so as to be recessed toward the inside of the container 1 as compared with the remaining region where the ventilation portion 16 is not formed, so that the ventilation portion 16 is separated from the ground. It is possible to smoothly inject the external air into the space between the outer layer 11 and the inner layer 12 through the ventilation portion 16.

The inner layer 12 may be detachably housed inside the outer layer 11, and a storage space may be provided inside to house the toothpaste P. The inner layer 12 may be another layer formed separately from the outer layer 11 by the multi-layer blow molding of the container body 10. The inner layer 12 can form the inlet 13 of the container in a state of being bonded to the outer layer 11, and can be peeled off at the remaining portion other than the inlet 13 of the container.

With reference to FIGS. 3 and 4, the inner layer 12 includes a storage space inside, and the volume can be reduced according to the capacity of the toothpaste P to be stored. That is, a part or all of the inner layer 12 can come into contact with the inner wall of the outer layer 11 according to the amount of the toothpaste P accommodated in the storage space, and the volume of the inner layer 12 is reduced by discharging the toothpaste P. A part of the inner layer 12 may be peeled off from the inner wall of the outer layer 11. Therefore, the inner layer 12 may be made of a material whose volume can be changed according to the capacity of the toothpaste P accommodated in the storage space. Preferably, the inner layer 12 has a hardness even lower than that of the outer layer 11, and a change in volume can be easily generated as compared with the outer layer 11. For example, the inner layer 12 may consist of one or more selected from the group consisting of ethylene vinyl alcohol, low density polyethylene, and nylon.

The inner layer 12 may be coupled to the cap 14 and the airless pump 30 via the inlet 13 of the container, stores the toothpaste P in the internal storage space via the inlet 13 of the container, and via the suction port of the tube. It only discharges and does not have another vent. Therefore, since the toothpaste P housed in the storage space of the inner layer 12 can be stored and discharged in a state where it does not come into contact with the outside air, the toothpaste P can be stored in a state where it does not dry. Further, long-term discharge stability can be ensured by preventing the current state of wear inside the nozzle 20 and the airless pump 30 due to 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 4.0 kgf. The pumping pressure may be the same as the external force required to push the nozzle 20 connected to the airless pump 30 in the vertical lower end direction. As will be described later, the viscosity of the toothpaste that can be used in the pump-type toothpaste container according to the embodiment of the present invention may be 10,000 to 70,000 cP, and the minimum pumping pressure required for pumping the toothpaste having the 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 toothpaste pumping may be 4.0 kgf. Further, by using the container body 10 including the outer layer 11 and the inner layer 12, the pumping pressure is within the above range even if the remaining amount of the toothpaste P contained in the container 1 decreases due to the discharge and use of the toothpaste. Can be held inside.

The pumping amount of the airless pump 30 at one time may be 0.5 to 3.5 g. The pumping amount may be the same as the amount of toothpaste discharged through the discharge port 21 by pushing the nozzle 20 in the vertical lower end direction all at once with an external force.

The airless pump 30 may be coupled to the tube 40 through the lower end of the housing 31 that forms the appearance of the pump. With reference to FIG. 1, the tube 40 may be inserted and fixed at the lower end of the housing 31. The outer wall of the tube 40 may be inserted and fixed so as to be sandwiched between the inner walls of the lower end portion of the housing 31. Although not shown, the tube 40 may supply the toothpaste P to the airless pump 30 only through the tube 40 by being inserted to the lower end of the valve provided inside the housing 31 and brought into close contact with the tube 40.

The tube 40 is located inside the storage space in the inner layer 12, and can communicate with the airless pump 30 to communicate the toothpaste. Specifically, one end of the tube 40 is located inside the storage space and comes into contact with the toothpaste P housed inside the storage space, and the remaining end is connected to the discharge path of the airless pump 30. The toothpaste P housed in the storage space can be communicated with the airless pump 30. More specifically, the remaining end of the tube 40 may be inserted and fixed inside the housing 31 of the airless pump 30.

In the pump-type toothpaste container according to the first embodiment of the present invention, by locating the tube 40 as described above, even when the volume of the inner layer 12 decreases and the inner layer 12 contracts according to the discharge and use of the toothpaste P. A space of at least the cross-sectional area of the tube 40 or more can be secured at the inlet 13 of the container, and the amount of toothpaste P pumped via the airless pump 30 can be kept constant. Therefore, the material of the tube 40 must be harder than the inner layer 12 and retain its shape even under the pressure due to the contraction of the inner layer 12 so that the toothpaste P can communicate with it. For example, the tube 40 may consist of, but is not limited to, one or more selected from the group consisting of polypropylene, high density polyethylene, polycarbonate, and polyethylene terephthalate. 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 length in the depth direction of the storage space of the inner layer 12. That is, it is possible to prevent one end of the tube 40 from coming into contact with the bottom portion of the storage space of the inner layer 12 by utilizing the fact that the volume of the inner layer 12 is reduced according to the discharge of the toothpaste. As will be described later, the viscosity of the toothpaste that can be used in the pump-type toothpaste container according to the embodiment of the present invention may be 10,000 to 70,000 cP, and the toothpaste having the viscosity is pumped without the squeezing phenomenon of the inner layer. The minimum length of the tube 40 required for the above may be 1/10 of the length of the storage space in the depth direction. By utilizing the fact that the volume of the inner layer 12 is reduced in response to the discharge of toothpaste, the length of the tube 40 can be prevented from exceeding 9/10. By using the tube 40 having a length that satisfies the above range, it is possible to prevent the container inlet 13 from being narrowed due to the contraction of the inner layer 12, and to maintain the pumping pressure and the pumping amount that satisfy the above range. Can be done. Preferably, the length of the tube 40 may be 1/10 to 9/10 of the length in the depth direction of the storage space of the inner layer 12.

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

As described above, in the first embodiment, in the pump-type toothpaste container 1 of the delamination type provided with the airless pump 30, the toothpaste P is discharged by inserting and fixing the tube 40 into the lower end portion of the housing 31. It is possible to prevent the inlet 13 of the container from being narrowed due to the volume reduction of the inner layer 12 and to achieve a stable discharge of the toothpaste P.

2 to 4 show a pump-type toothpaste container according to Example 2 of the present invention, and FIGS. 2a and 2b are cross-sectional views of a pump-type toothpaste container according to Examples 2-1 and 2-2, respectively. FIG. 2c shows the appearance of the housing of the pump-type toothpaste container according to the second embodiment, and FIG. 2d is an enlarged cross-sectional view of the housing. FIGS. 3 and 4 show the volume change of the inner layer 12 due to the use of the pump-type toothpaste container according to Examples 2-1 and 2-2, respectively.

Referring to FIG. 2, the pump-type toothpaste container 2 according to Examples 2-1 and 2-2 of the present invention includes a container body 10, a nozzle 20, an airless pump 30, and a tube 40, and the housing 31 of the airless pump 30. Further includes a suction port 35.

In the following, the points where the present Examples 2-1 and 2-2 are different from those in the above-described Example 1 will be mainly described, and the parts omitted from the description will be replaced with the above-mentioned contents.

The airless pump 30 may be coupled to the tube 40 through the lower end of the housing 31 that forms the appearance of the pump. At this time, one or more first ribs 33 projecting in the central direction may be provided on the inner wall of the lower end portion of the housing 31 and used for coupling with the tube 40. The shape of the first rib 33 is not limited as long as it prevents deformation of the housing 31 and can be used for coupling with the tube 40.

Referring to FIGS. 2c and 2d, the lower end of the housing 31 is provided with one or more suction ports 35 on the side surface so that the toothpaste P can be sucked into the airless pump 30. The suction port 35 may be arranged between one or more first ribs 33 provided in the housing 31, and one or more suction ports 35 are provided between the one or more first ribs 33. You may. Alternatively, one or more first ribs 33 may be arranged on one suction port 35 so as to cross the suction port 35. The suction port 35 may be circular or square, but is not limited thereto.

Although not shown, it is possible to prevent the suction port 35 from being clogged due to the narrowing of the inner layer 12 by providing the suction prevention rib on the outer wall of the lower end portion of the housing 31. One or more suction prevention ribs may be provided on the outer wall of the housing 31, or may be provided between one or more suction ports 35. Alternatively, a plurality of suction prevention ribs may be formed on one suction port 35, but the suction port 35 may not be sealed. For example, the suction prevention ribs are vertically arranged on the suction port 35 to ensure the separation between the suction port 35 and the inner layer 12 even when the inner layers 12 are narrowed to each other, and the toothpaste P through the suction port 35. Can be smoothly sucked.

Referring to FIG. 2a, in the second embodiment, the tube 40 is inserted and fixed to the lower end of the first rib 33 through the lower end of the housing 31, so that the tube 40 has one or more suction ports. 35 can be unblocked. Therefore, in the pump-type toothpaste container 2 according to the present embodiment 2-1 the toothpaste P can be sucked at the same time at the suction port 35 and the end of the tube 40 formed on the side surface of the housing 31 of the pump and discharged to the discharge port 21. it can.

In the existing toothpaste container, when the toothpaste has a high viscosity, the toothpaste stored in the container is discharged from the vicinity of the suction port, and the fluidity of the toothpaste decreases, so that the pump is blown and pumped during use. A defective phenomenon sometimes occurred.

Referring to FIG. 3, in the present embodiment 2-1 in the pump-type toothpaste container 2, the first rib 33 is provided inside the housing 31 of the airless pump 30, and the tube 40 is inserted into the lower end of the housing 31. By fixing to the lower part of the first rib 33 and forming the suction port 35 on the side surface of the housing 31, the toothpaste P is simultaneously sucked at the suction port 35 formed on the side surface of the housing 31 of the pump and the end of the tube 40. Can be made possible. As a result, when the viscosity of the toothpaste P is high, the toothpaste P is not discharged only around one of the containers 2, so that the pump is prevented from being blown and pumping failure is prevented, and the toothpaste P is stably discharged. Can be achieved.

With reference to FIG. 2b, in Example 2-2, the tube 40 may be inserted and fixed between the plurality of first ribs 33. The tube 40 is inserted to the lower end of the valve provided inside the housing 31 and brought into close contact with the tube 40, so that the toothpaste P can be supplied to the airless pump 30 only through the tube 40. Therefore, the pump-type toothpaste container 2 according to the second embodiment can suck the toothpaste P only at the end of the tube 40 and discharge it to the discharge port 21.

Referring to FIG. 4, in the pump-type toothpaste container 2 according to the present embodiment 2-2, the toothpaste P can be sucked only at the end of the tube 40.

FIG. 9 shows a pump-type toothpaste container according to a seventh embodiment of the present invention, and FIG. 9a is a cross-sectional view of the pump-type toothpaste container. FIG. 9a shows a state in which the cap and the nozzle are excluded in order to show the state of the upper end portion of the airless pump and the tube in detail. 9b and 9c are a cross-sectional view of the tube and a conceptual diagram showing how to manufacture the tube, respectively.

Referring to FIG. 9, the pump-type toothpaste container 7 according to the seventh embodiment of the present invention includes a container body 10, a nozzle 20, an airless pump 30, and a tube 40.

The airless pump 30 may be coupled to the tube 40 through the lower end of the housing 31 that forms the appearance of the pump. Although not shown, since the diameter of the tube 40 is larger than the outer diameter of the lower end portion of the housing 31, as in the above-described embodiment, at least a part of the airless pump 30 is fixed by inserting it into the inner wall of the tube 40. May be good.

As a result, when the viscosity of the toothpaste P is high, the toothpaste P is prevented from being discharged only around one of the containers 7, so that the pump can be prevented from being blown idle and the pumping failure can be prevented. The tube 40 of this embodiment can be easily manufactured by using the tube cut knife 50 and the suction port cut knife 51.

Hereinafter, examples 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, which is difficult to use with a conventional deep tube pump type container, but is suitable for the pump type toothpaste container according to the present invention.

The dentifrice composition according to one embodiment of the present invention may contain water, a thickener, an abrasive, and a polyol. In addition, the dentifrice composition may further contain a solubilizer, a flavoring agent, a sweetener, a medicinal agent, a pH adjuster, a preservative, a binder, a foaming agent, and the like, depending on the purpose of use.

As the water, the water used for toothpaste compositions in the art can be used. 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 can be contained in an amount of 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 solubility of the toothpaste in the oral cavity is significantly reduced, and the phenomenon that the lumps grow when the composition is discharged becomes severe. If the content exceeds 50% by weight, the shape of the toothpaste is retained. The sex is significantly reduced.

The thickener can adjust the viscosity of the dentifrice composition to 25,000 to 70,000 cP, which is a viscosity suitable for being contained and discharged in the pump-type dentifrice container of the present invention. The thickener may be an organic or inorganic binder. As the organic thickener, one or more organic polymers 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 or the like may be used, but silica for thickening is preferably used.

The thickening silica may contain precipitated silica or colloidal silicon dioxide, which can mean that the BET specific surface area is 500 m ² / g or more. Precipitated silica is produced by mixing sand and caustic soda, dissolving it in water to carry out a sol-gel reaction, and then adding sulfuric acid, and adjusting the time and conditions of the sol-gel reaction to 500 m ² / g. A thickening silica having the above BET specific surface area can be produced. Colloidal silicon dioxide can be produced by spray-injecting silicon tetrachloride and then burning it. Since the thickening silica has a higher specific surface area than the polishing silica and can absorb more water, the viscosity of the composition with time can be increased. In addition, the silanol group (-SiOH) contained in the thickening silica strongly interacts with the adjacent silanol group by hydrogen bonding, and can enhance the elasticity of toothpaste and improve the shape retention. .. The thickening silica can be contained 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 thickening silica is added, the shape retention of the toothpaste cannot be improved, and if it is used in excess of 8% by weight, the shape retention is improved, but the viscosity is excessively increased. As a result, the discharge pressure rises and discharge becomes impossible.

The solubilizer can solubilize substances having low solubility in water, and those used in toothpaste compositions in the art can be used. For example, polyglyceryl-3 methylglucose disterate, oleth-10, oleth-10 / polyoxyl-10 oleyl ester NF, ceres-10, PEG-8 laurate, cocamide MEA, polysorbate 60NF, polysorbate 60, polysorbate 80, isosteares-20, One or more selected from the group consisting of polysorbate 80NF, PEG-20 methylglucose sesquistearate, ceteares-20, oleth-20, steareth-20, steareth-21, ceres-20, poloxamer 184, and poloxamer 407. It may be, but it is not limited to this.

The abrasive has a function of removing plaque in the oral cavity, and those used in dentifrice compositions in the art can be used. For example, it may be one or more selected from the group consisting of hydrous silicon dioxide, silicon dioxide, precipitated silica, calcium carbonate, polyethylene, cellulose, and zeolite, but is not limited thereto. The abrasive can be contained in an amount of 5% to 18% by weight based on 100% by weight of the toothpaste. If the abrasive is less than 5% by weight, the organic binder may cause a slimy feel and a low refreshing feel when brushing teeth, and if used in excess of 18% by weight, the pump piston will wear out. Therefore, the life of the pump is shortened and the discharge stability is lowered.

The polyol can prevent wear of the nozzle and pump due to the above-mentioned abrasive of the toothpaste composition, and can prevent coagulation at the discharge port of the toothpaste container in contact with air. As the polyol, those used in toothpaste compositions in the art can be used. 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 contain at least one of a liquid phase and a solid phase polyol, and sorbitol can be used as the solid phase polyol. The polyol can be contained in an amount of 2% by weight to 70% by weight based on 100% by weight of toothpaste. The toothpaste composition according to this example can be used by mixing a liquid phase polyol and sorbitol, and the solid sorbitol can be mixed in the form of an aqueous solution. The ratio of sorbitol (70% aqueous solution) to polyol may be 1: 0.1 to 1: 4. When the liquid phase and solid phase polyols are mixed and used in this way, the liquid phase polyols are hydrobonded to the solid phase polyols to minimize the evaporation of water in the mixture, and even if the water evaporates. It becomes possible to prevent the formation of a strong network of polyols. Therefore, it is possible to solve the problem of solidification at the discharge port portion of the toothpaste container that is in contact with air when the solid phase polyol is used alone.

The flavoring agent remains in the oral cavity and continuously emits fragrance, and mint such as peppermint and spearmint, eugenol, methyl salicylate, wintergreen extract, melon extract, strawberry extract, and orange extract. It may be, but is not limited to, any one or more selected from the group consisting of.

The sweetener is added to overcome the taste of the toothpaste composition and is selected from the group consisting of saccharin, sucralose, sugar, xylitol, lactose, mannitol, maltitol, erythritol, aspartame, and taurine. It may be, but is not limited to, one or more or pharmaceutically acceptable salts thereof.

Medicinal agents can be added for oral hygiene, and ingredients having effects such as dental caries prevention, remineralization, periodontal disease prevention, tartar deposition prevention, and whitening can be used. As a medicinal agent used for the purpose of preventing dental caries, compounds capable of supplying fluorine ions such as sodium fluoride, sodium monofluorophosphate and tin fluoride can be used. A remineralizing agent can also act as a caries preventive. Remineralization regenerates and restores hydroxyapatite, the main constituent of teeth, either supplying calcium and phosphate ions simultaneously or shifting the chemical equilibrium in the oral cavity toward the production of hydroxyapatite. Those containing calcium divalent cations and hydroxyapatite anions can be used so that they can be used. For example, hydroxyapatite, calcium dibasic phosphate, calcium chloride, casein phosphopeptide, calcium glycerophosphate, sodium primary phosphate, sodium dibasin phosphate, sodium tertiary phosphate, potassium dibasin phosphate, potassium dibasin phosphate, and It may be 1 or more selected from the group consisting of potassium tertiary phosphate. As a medicinal agent for preventing periodontal disease, isopropylmethylphenol, cyclohexidine, cetylpyridinium chloride, triclosan, xanthrizole, etc., which have a bactericidal action against harmful microorganisms in the oral cavity, may be used, and anti-gingival agents. Vitamin, enzyme, aminocaproic acid, allantoin, etc. may be used for the flame action. Medicinal agents used for the purpose of preventing tartar deposition include sodium pyrophosphate, acidic sodium pyrophosphate, potassium pyrophosphate, sodium metaphosphate, etc., and medicinal agents exhibiting a whitening effect include hydrogen peroxide, carbamide peroxide, and the like. There are calcium peroxide and so on.

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

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

Foaming agents can be added to facilitate the formation of foam when using the toothpaste composition.

In addition, the toothpaste composition according to this example may further contain polyacrylic acid or a pharmaceutically acceptable salt thereof. Polyacrylic acid is a polymer capable of inducing an electrostatic repulsive force by converting −COOH, which is a functional group, into −COO ⁻ under the condition of a hydrogen ion concentration of 4 to 10, and having elasticity. Polyacrylic acid has much higher elasticity than polymers commonly used for toothpaste such as cellulose gum and xanthan gum. This allows toothpastes further containing polyacrylic acid or a pharmaceutically acceptable salt thereof to have elasticity as well as viscosity. Toothpaste compositions further containing polyacrylic acid or a pharmaceutically acceptable salt thereof can improve the shape retention of the toothpaste, but at low viscosities the fluidity is low and the remaining amount is high. Its use is restricted in deep pump containers and can be applied to pump-type toothpaste containers as in the embodiments described above to provide improved shape retention.

Polyacrylic acid or a pharmaceutically acceptable salt thereof can be contained in an amount of 0.2% by weight to 1.5% by weight based on 100% by weight of the composition. If less than 0.2% by weight of polyacrylic acid or a pharmaceutically acceptable salt thereof is used, the shape retention of the toothpaste will not be improved, and if it is used in excess of 1.5% by weight, the elasticity and viscosity will increase. The discharge pressure is improved and the discharge stability is lowered.

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

Hereinafter, preferred production examples of the present invention will be described in detail.

Production example and comparative example. Manufacture of toothpaste composition

Toothpaste compositions according to Production Examples and Comparative Examples were prepared with the components shown in Tables 1 and 2 below and% by weight, respectively. Ingredients such as purified water, sorbitol, flavoring agents, foaming agents, medicinal agents, and surfactants are first mixed, then additional abrasives, thickeners and medicinal agents are added and then mixed in a vacuum to brush the teeth. The composition was produced.

Experimental example 1. Viscosity of toothpaste composition The toothpaste composition prepared in the production example and the comparative example was rotated 5 times at 20 rpm using spindles 5 to 7 with a Brookfield viscometer RVT type at 25 ° C., and then the initial viscosity value (cP) was obtained. It was measured. After the toothpaste composition was sealed and stored for 1 month, the viscosity value over time (cP) was measured by the same method, and the results are shown in Table 3 below.

The toothpaste composition according to this production example contained silica for thickening and achieved a high viscosity of 25,000 cP or more based on the initial viscosity. In Comparative Examples 1 and 4 in which the thickening silica was not used, sufficient initial viscosity was not secured, and in Comparative Example 3 in which the thickening silica was excessively used as compared with the present production example, the lapse time after 1 month. The viscosity reached 100,000 cP, making it difficult for the pump to discharge toothpaste.

Experimental example 2. Dischargeability and remaining amount for each container The toothpaste composition prepared in the production example and the comparative example has a structure in which a pump-type toothpaste container (delamination container) according to Example 2 of the present invention and a deep tube are connected to a conventional air pump. Fill a deep pump toothpaste container containing the above and use the Texture Analyser (TA instrument) to discharge at a rate of once a minute, discharge until no longer discharged, and evaluate the discharge performance. The results are shown in the table below. Shown in 4.

The presence or absence of discharge was evaluated based on the remaining amount after discharge being 30% of the total filling amount, and when it was 30% or more, it was evaluated that the toothpaste composition was not discharged from the corresponding container. When the remaining amount exceeded 50%, it was evaluated that the measurement of the remaining amount was not significant. (Presence / absence of discharge ○: Remaining amount after discharge is less than 30%, ×: Remaining amount after discharge is 30% or more)

The toothpaste compositions prepared in Production Examples and Comparative Examples were filled in the container according to Example 2 and the deep pump toothpaste container and stored for 1 month, and then the discharge property was evaluated by the same method, and the results were evaluated in Table 5 below. It was shown to.

As shown in Tables 4 and 5, the toothpaste composition according to the present production example has excellent discharge property in the delamination container according to the second embodiment of the present invention at the initial stage and after one month, and the remaining amount is 8% or less. Met. The toothpaste composition having the content ratio of sorbitol and polyol according to Production Examples 11 to 16 was also excellent in dischargeability in the delamination container, and the remaining amount was 6% or less.

In Comparative Example 2, polishing silica is used instead of thickening silica, and it can be discharged from the result of viscosity, but it can be seen that the piston is worn and the discharge stability is poor. In Comparative Example 3, the thickening silica was excessively used and the increase in viscosity with time was too large, so that the airless pump could not discharge the contents, and the content at the discharge port was 4 kgf or more. A large discharge pressure was required.

Experimental example 3. Shape retention after ejection of toothpaste composition The toothpaste composition prepared in Production Examples and Comparative Examples is filled in a pump-type toothpaste container according to Example 2 of the present invention, and then pumped once to display a scale. It was discharged in a lump on the plate.

The height of the lump was measured 5 seconds after the discharge, and the ratio (height / diameter) to the diameter of the discharge port of the pump-type toothpaste container was shown to evaluate the shape retention of the discharged lump of toothpaste. .. When the shape retention property is 0.70 or more, the shape does not collapse even when the toothbrush is ejected, and the toothbrush does not bleed into the inside of the toothbrush hair.

It can be seen that the toothpaste compositions of this production example and comparative example 3 containing silica for thickening are excellent in shape retention. The toothpaste compositions according to Comparative Examples 1, 2 and 4 have a shape-retaining property that causes them to run off when discharged into a toothbrush. Comparative Example 3 has good shape retention, but the increase in viscosity is too large to discharge all of it, and a high discharge pressure of 4 kgf or more is required, so that it is not suitable for use in pump toothpaste.

Experimental example 4. Discharge stability by drying the discharge port after discharging the toothpaste composition The toothpaste composition prepared in the production example and the comparative example is filled in the pump-type toothpaste container according to the second embodiment of the present invention, and then pumped once and discharged. did. With the toothpaste composition remaining in the discharge port of the container, leave it at room temperature for 1 month, then pump it once again to measure the discharge pressure, check if the discharge port is clogged, and check the discharge stability. evaluated. (Discharge pressure evaluation ○: less than 4 kgf, ×: 4 kgf or more, or the discharge port is clogged)

A toothpaste composition using liquid-phase and solid-phase polyols or only liquid-phase polyols having the compositions according to Production Examples 11 to 16 was discharged without clogging the discharge port of the container. In the toothpaste composition according to Comparative Example 5, it was observed with the naked eye that the discharge port of the container was clogged, the discharge pressure was 4 kgf or more, and it was evaluated that there was no discharge stability.

The present invention is not limited to the examples described above, and may include a combination of the above examples or a combination of at least one of the above examples and a known technique as yet another example.

The present invention has been described in detail above through specific examples, but this is for the purpose of specifically explaining the present invention, and the present invention is not limited thereto, but within the technical idea of the present invention. It is clear that it can be modified or improved by someone with normal knowledge of the field.
