Description

Pump-type toothpaste container and toothpaste composition

Technical Field

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 sucking toothpaste stored in the container and discharging the toothpaste through a nozzle, and a toothpaste composition stored in the container.

Background

Generally, toothpaste paste is packed in a tube-shaped soft container and commercialized, but such a tube-shaped toothpaste container has a problem that it is necessary to push the container with a strong force to squeeze the toothpaste out according to circumstances due to high viscosity of the toothpaste, and has inconvenience in that it is difficult to discharge the remaining toothpaste.

As a humectant and a humectant, sorbitol (sorbitol) is mainly used for toothpaste. As sorbitol, sorbitol in an approximately 70% aqueous solution state is used, but it has a property of rapidly turning into a solid as water is dried. In particular, since solid powder is contained as an abrasive in toothpaste, it is easily solidified when it comes into contact with air. In view of such problems, in recent years, attempts have been made to adapt a deep tube pump type container widely used in shampoo, body wash, or the like to toothpaste for consumers to use conveniently.

Such a deep tube pump type container has advantages of good versatility and easy introduction due to low price, but has a structure in which the content is excessively left after final use and external air freely flows into the container through a nozzle, so that when used as a toothpaste container, toothpaste is dried with the increase of use time, and thus viscosity gradually increases, a large force is required at the time of discharge, and toothpaste becomes hard and cannot be smoothly discharged, and when toothpaste becomes hard, abrasives contained in toothpaste are solidified, causing a problem of abrasion of a piston or a nozzle of a pump.

On the other hand, in order to use a deep tube pump type container, toothpaste needs to flow toward the lower end of the pump in the container by its own weight or gravity. However, toothpaste in a highly elastic form flows relatively slowly downward, thereby causing excessive toothpaste retention in the container. In japanese laid-open patent publication No. 2009-: the inner layer containing toothpaste shrinks to cause the shrinking phenomenon that the shrunk inner layer blocks the inlet of the container, so that a considerable amount of stored toothpaste cannot be communicated with the pump dispenser and remains.

Detailed Description

The objects, certain advantages and novel features of the invention will become more apparent from the following detailed description of the preferred embodiment when considered in conjunction with the drawings. In the present specification, when reference numerals are given to constituent elements of respective drawings, the same reference numerals are used as much as possible for the same constituent elements even though they are shown in different drawings. In describing the present invention, when it is determined that the detailed description of the related known technology makes the gist of the present invention unclear, the detailed description thereof will be omitted.

In the following description, a pump-type container refers to a container that discharges the content stored in the container to the outside through a discharge portion by a pump action of a pressing portion such as a nozzle.

The term "intermediate layered container" as used herein means a container comprising an outer layer and an inner layer, wherein the inner layer is configured to be peelable from the outer layer.

The viscosity of the toothpaste composition in the following description is a value measured by a Brookfield viscometer (DV-III Ultra Rheometer) model RVT at 25 ℃ after rotating 5 times at 20rpm using a spindle number 5 to 7.

The low viscosity and the high viscosity are relative values and do not represent specific values, but the low viscosity is, for example, a viscosity in the range of 10,000 to 25,000cP, and the high viscosity is a viscosity in the range of 25,000cP or more, preferably 25,000 to 70,000 cP.

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

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

The container body 10 includes an outer layer 11 and an inner layer 12, and includes a receiving space therein to receive toothpaste P. Specifically, the outer layer 11 forms an external appearance of the container and includes a ventilation portion 16, and the inner layer 12 is detachably accommodated in the outer layer 11 and includes an accommodating space therein to accommodate the toothpaste P. That is, the container body 10 is a layered container.

The container 1 may be vertically erected on the ground, and for this reason, a part or the whole of a surface of the container body 10 contacting the ground is formed in a flat structure to be vertically erected on the ground. The form and size of the container body 10 are not limited as long as the container body 10 can be vertically erected on the floor surface regardless of the amount of the toothpaste P stored in the container, in particular, in a state where the container 1 includes all of the container body 10, the nozzle 20, the air pump 30, the tube 40, and the toothpaste P stored therein, but the form of the container body 10 may be, for example, a cylinder, a cone, an elliptic cylinder, a rectangular parallelepiped, or a polygonal prism. Preferably, the container body 10 has a conical shape, and more preferably, at least a portion of the body is formed to have a shape that is narrow at the top and wide at the bottom in consideration of the weight center of the container body 10.

The container body 10 is produced by multilayer blow molding of a thermoplastic resin. As the molding method for injecting a thermoplastic resin into a previously prepared mold (mold) and adjusting the temperature to stretch the thermoplastic resin into the form of the mold, two or more different thermoplastic resins can be used as the thermoplastic resin, and the thermoplastic resin can be molded into a multilayer structure by blowing hot air into the resin simultaneously or sequentially to form the multilayer structure of the outer layer 11 and the inner layer 12. In the case of multilayer blow molding, the resin and air injection portion may be molded in the form of the container inlet 13. That is, the outer layer 11 and the inner layer 12 form the container inlet 13 in a state of being bonded to each other, and are peelable at a portion other than the remaining portion of the container inlet 13. Therefore, the container inlet 13 communicates with the housing space of the inner layer 12 and does not communicate with the inside of the outer layer 11. The container inlet 13 may be used for injecting and discharging toothpaste P for combining the container body 10 with the cap 14. The toothpaste P is stored in the inside of the container body 10 and discharged to the outside only through the above-mentioned container inlet 13, and the cross section of the container inlet 13 is circular.

The outer layer 11 forms the appearance of the container 1 and is provided with a ventilation portion 16. The outer layer 11 may be formed of one or more selected from the group consisting of polypropylene, high-density polyethylene, polycarbonate, and polyethylene terephthalate, and has a hardness to such an extent that the container 1 can stand vertically on the ground. Preferably, the outer layer 11 has a relatively higher hardness than the inner layer 12. The outer layer 11 is opaque and does not transmit a part or all of the shape of the inner layer 12. This prevents the quality of the toothpaste from changing due to the transmission of external ultraviolet rays, and prevents the inner layer 12, which will be described later, from being deformed on the outside, thereby improving the aesthetic appearance.

The ventilation part 16 is formed on one surface of the outer layer 11, preferably on the bottom surface of the container 1 contacting the ground, and communicates air to the inside and outside of the outer layer 11. When the toothpaste P in the space for containing the inner layer 12 is discharged by the air pump 30 described later, the air vent 16 injects outside air into the space between the outer layer 11 and the inner layer 12, so that the toothpaste P contained in the space for containing the inner layer 12 can be smoothly discharged without contacting the outside air, thereby achieving stable discharge of the toothpaste. More specifically, the form, size and number of the ventilation parts 16 are not limited as long as they are formed in the outer layer 11 to inject outside air into the space between the outer layer 11 and the inner layer 12 through the outer layer 11. Preferably, the ventilation portion 16 is formed in a slit (slit) shape in the outer layer 11 by a pinch-off process in the multilayer blow molding of the container body 10. The pinch-off process cuts off the folded portion of the outer layer 11 at the lower end portion where the outer layer 11 and the inner layer 12 are pinched together in the multi-layer blow molding, thereby forming the vent portion 16 in a slit shape at the lower end portion of the outer layer 11.

The bottom surface of the container 1, which is in contact with the ground surface, of the outer layer 11 is divided into one region where the ventilation part 16 is formed and the remaining region where the ventilation part 16 is not formed, and the ventilation part 16 is provided with a protrusion (not shown) so that outside air can be smoothly injected. The protrusion separates the bottom surface of the container 1 from the ground and smoothly injects the outside air into the space between the outer layer 11 and the inner layer 12 through the ventilation portion 16. In particular, by separating one region where the ventilation portion 16 is formed from the ground, even when water is accumulated on the ground, the outside air can be smoothly injected through the ventilation portion 16. Further, the one region in which the vent part 16 is formed is recessed toward the inside of the container 1 with respect to the remaining region in which the vent part 16 is not formed, so that the vent part 16 is separated from the ground and outside air is smoothly injected into the space between the outer layer 11 and the inner layer 12 through the vent part 16.

The inner layer 12 is detachably received in the outer layer 11, and has a receiving space therein for receiving the toothpaste P. The inner layer 12 is a separate layer formed separately from the outer layer 11 according to the multi-layer blow molding of the container body 10. The inner layer 12 forms a container inlet 13 in a state of being bonded to the outer layer 11, and peeling can be achieved in a portion other than the container inlet 13.

Referring to fig. 3 and 4, the inner layer 12 is reduced in volume according to the capacity of the toothpaste P contained therein including the containing space. That is, a part or the whole of the inner layer 12 is brought into contact with the inner wall of the outer layer 11 according to the amount of the toothpaste P stored in the storage space, and the volume of the inner layer 12 is reduced according to the discharge of the toothpaste P, so that a part of the inner layer 12 is peeled off from the inner wall of the outer layer 11. Therefore, the inner layer 12 is made of a material whose volume changes according to the capacity of the toothpaste P stored in the storage space. Preferably, the inner layer 12 has a lower hardness than the outer layer 11 and is more likely to change in volume than the outer layer 11. For example, the inner layer 12 is composed of one or more selected from the group consisting of ethylene vinyl alcohol, low density polyethylene, and nylon.

The inner layer 12 is coupled to the cap 14 and the air pump 30 through the container inlet 13, stores the toothpaste P in the internal storage space through the container inlet 13, and discharges the toothpaste P through the suction port of the tube without providing a separate ventilation portion. Therefore, the toothpaste P stored in the storage space of the inner layer 12 is stored and discharged without contacting with the outside air, and thus the toothpaste P can be stored in a wet state. Further, the wear phenomenon in the nozzle 20 and the air pump 30 due to the solidification of the abrasives in the toothpaste P, which may occur when the toothpaste P is dried, is prevented, and the long-term discharge stability can be ensured.

The suction pressure of the air pump 30 is 1.5 to 4.0 kgf. The suction pressure may be the same as an external force required to press the nozzle 20 connected to the air pump 30 in a vertical lower end direction. As described later, the viscosity of toothpaste used in the pump type toothpaste container according to one embodiment of the present invention is 10,000 to 70,000cP, and the minimum suction pressure required to suck toothpaste of such a viscosity may be 1.5 kgf. The container body 10 including the above outer layer 11 and inner layer 12 was used so that the maximum suction pressure required in the toothpaste suction was 4.0 kgf. Further, by using the container body 10 including the outer layer 11 and the inner layer 12, the suction pressure can be maintained within the above range even when the remaining amount of the toothpaste P stored in the container 1 is reduced according to the discharge and use of the toothpaste.

The amount of one suction of the air pump 30 is 0.5 to 3.5 g. The suction amount corresponds to an amount of toothpaste discharged through the discharge port 21 when the nozzle 20 is pressed to the end in a direction perpendicular to the lower end by an external force at one time.

The air pump 30 is coupled with the tube 40 through a lower end portion of the housing 31 forming an external appearance of the pump. Referring to fig. 1, the tube 40 is inserted and fixed through the lower end portion of the housing 31. The outer wall of the pipe 40 is inserted and fixed so as to be inserted between the inner walls of the lower end portion 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 closely attached, and the toothpaste P is supplied to the air pump 30 only through the tube 40.

The tube 40 is positioned in the receiving space of the inner layer 12, and communicates with the air pump 30 and the toothpaste. Specifically, one end of the tube 40 is positioned in the housing space to contact the toothpaste P housed in the housing space, and the remaining end is connected to the discharge path of the air pump 30 to communicate the toothpaste P housed in the housing space with the air pump 30. More specifically, the remaining end of the tube 40 is inserted into and fixed to the inside of the housing 31 of the air pump 30.

In the case of the pump type toothpaste container according to embodiment 1 of the present invention, the tube 40 is provided as described above, so that even in the case where the volume of the inner layer 12 is reduced according to the discharge and use of the toothpaste P and thus the inner layer 12 is contracted, a space at least above the cross section of the tube 40 is secured at the container inlet 13, thereby maintaining the amount of the toothpaste P sucked by the air pump 30 to be constant. Therefore, the tube 40 should be made of a material harder than the inner layer 12 so as to maintain its shape and allow the toothpaste P to communicate even under pressure caused by the contraction of the inner layer 12. For example, the tube 40 may be composed 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 receiving space of the inner layer 12. That is, the one end of the tube 40 does not abut on 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 as the toothpaste is discharged. As will be described later, the viscosity of toothpaste used in the pump type toothpaste container according to one embodiment of the present invention is 10,000 to 70,000cP, and the minimum length of the tube 40 required for sucking toothpaste having such a viscosity without the inner layer narrowing phenomenon is 1/10 of the depth direction length of the storage space. By taking advantage of the above-mentioned reduction in volume of the inner layer 12 as the toothpaste is discharged, the length of the tube 40 does not exceed 9/10. By using the tube 40 having a length satisfying the above range, the constriction of the container inlet 13 due to the contraction of the inner layer 12 is prevented, and the suction pressure and the amount of suction per one time satisfying the above range can be maintained. 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 7mm for a toothpaste composition having a low viscosity of 10,000 to 25,000cP, and 5 to 9mm for a toothpaste composition having a high viscosity of 25,000cP or more. The thickness of the tube 40 may be 0.5 to 1.5 mm.

As described above, in the pump type toothpaste container 1 of the present embodiment 1 having the air pump 30 in the layered form, the tube 40 is inserted and fixed into the lower end portion of the housing 31, so that even when the toothpaste P is discharged and used, the container inlet 13 is prevented from being narrowed due to the reduction in the volume of the inner layer 12, and the toothpaste P can be stably discharged.

Fig. 2 to 4 show a pump type toothpaste container according to example 2 of the present invention, fig. 2a and 2b show sectional views of the pump type toothpaste containers according to examples 2-1 and 2-2, respectively, fig. 2c is a view showing an external appearance of a housing of the pump type toothpaste container according to example 2, and fig. 2d is a view enlarging the sectional view of the housing. Fig. 3 and 4 are views showing changes in the volume of the inner layer 12 according to the use of the pump type toothpaste containers of examples 2-1 and 2-2, respectively.

Referring to fig. 2, the pump type toothpaste container 2 according to embodiments 2-1 and 2-2 of the present invention includes a container body 10, a nozzle 20, an air pump 30 and a tube 40, and the housing 31 of the air pump 30 further includes a suction inlet 35.

The following description will mainly be given of the differences between the present embodiments 2-1 and 2-2 and the above-described embodiment 1, and the description thereof may be replaced with those described above.

The air pump 30 is coupled with the tube 40 through a lower end portion of the housing 31 forming an external appearance of the pump. At this time, at least one 1 st rib 33 protruding toward the center is provided on the inner wall of the lower end portion of the housing 31 for coupling with the tube 40. The shape of the 1 st rib 33 is not particularly limited as long as it can prevent deformation of the housing 31 and can be used for coupling with the pipe 40.

Referring to fig. 2c and 2d, the lower end of the housing 31 has one or more suction ports 35 on the side surface thereof, and the toothpaste P is sucked into the air pump 30. The suction port 35 is disposed between the one or more 1 st ribs 33 provided in the housing 31, and the one or more suction ports 35 are provided between the one or more 1 st ribs 33. Alternatively, one or more of the 1 st ribs 33 may be disposed in one suction port 35 so as to cross the suction port 35. The shape of the suction port 35 may be a circle or a quadrangle, but is not limited thereto.

Although not shown, an adsorption prevention rib is provided on the outer wall of the lower end portion of the housing 31, so that the suction port 35 can be prevented from being blocked due to the narrowing of the inner layer 12. One or more suction prevention ribs are provided on the outer wall of the housing 31 and between the one or more suction ports 35. Alternatively, a plurality of adsorption preventing ribs may be formed on one suction port 35 without sealing the suction port 35. For example, the adsorption preventing ribs are vertically arranged on the suction port 35, and when the inner layers 12 are narrowed, the separation between the suction port 35 and the inner layers 12 is ensured, so that the toothpaste P can be smoothly sucked through the suction port 35.

Referring to fig. 2a, in example 2-1, the tube 40 is inserted and fixed to the lower end of the 1 st rib 33 through the lower end of the housing 31, so that the tube 40 does not block the one or more suction ports 35. Accordingly, the pump type toothpaste container 2 of this embodiment 2-1 sucks the toothpaste P at the suction port 35 formed at the side of the pump housing 31 and the end of the tube 40 at the same time and discharges it to the discharge port 21.

In the conventional toothpaste container, when the viscosity of the toothpaste is high, the toothpaste stored in the container is exhausted from the periphery of the suction port, the fluidity of the toothpaste is reduced, and the phenomena of idle driving of the pump and poor suction can occur during use.

Referring to fig. 3, in the present embodiment 2-1, a 1 st rib 33 is provided inside a housing 31 of an air pump 30 in a pump type toothpaste container 2, a tube 40 is inserted into a lower end portion of the housing 31 and fixed to a lower portion of the 1 st rib 33, and a suction port 35 is formed at a side surface of the housing 31, so that toothpaste P can be sucked in simultaneously at the suction port 35 formed at the side surface of the pump housing 31 and a distal end of the tube 40. Thus, when the viscosity of the toothpaste P is high, the toothpaste P is not used up only around either side of the container 2, and the pump is prevented from being driven empty and from being insufficiently sucked, thereby stably discharging the toothpaste P.

Referring to fig. 2b, in embodiment 2-2, the tube 40 is inserted between the plurality of 1 st ribs 33 and fixed. The tube 40 is inserted to the lower end of the valve provided inside the housing 31 and closely attached thereto, and the toothpaste P is supplied to the air pump 30 only through the tube 40. Therefore, the pump type toothpaste container 2 of this embodiment 2-2 sucks the toothpaste P only at the distal end of the tube 40 and discharges it toward the discharge port 21.

Referring to fig. 4, the pump type toothpaste container 2 of this embodiment 2-2 sucks toothpaste P only at the distal end of the tube 40.

Thus, the pump type toothpaste container 2 of this embodiment 2 adjusts the suction position of toothpaste to that of embodiment 2-1 or 2-2 by using one air pump 30 and pipes 40 having different diameters, so that toothpaste can be stably discharged according to the viscosity of toothpaste.

Referring to fig. 5, the pump type toothpaste container 3 according to embodiments 3-1 and 3-2 of the present invention includes a container body 10, a nozzle 20, an air pump 30 and a tube 40, and the housing 31 of the air pump 30 further includes a suction inlet 35.

The following description will mainly explain the differences between the present embodiments 3-1 and 3-2 and the above-described embodiment 1, and the description thereof may be replaced with the above-described ones.

The air pump 30 is coupled to the tube 40 through a lower end portion of the pump housing 31. At this time, portions having different diameters from each other are provided at the lower end portion of the housing 31. Specifically, the diameter of the tip portion is larger in the lower end portion of the housing 31, and thus there is a stopper projection 34 formed by the difference in diameter of the housing 31 at the boundary of the lower end portion and the tip portion of the inner wall of the housing 31.

Referring to fig. 5c and 5d, the lower end of the housing 31 has one or more suction ports 35 on the side surface to suck the toothpaste P into the air pump 30. Specifically, one or more suction ports 35 are provided at the upper end of the stopper projection 34 provided in the housing 31. The shape of the suction port 35 may be a circle or a quadrangle, but is not limited thereto.

Referring to fig. 5a, in embodiment 3-1, the tube 40 is inserted and fixed to the stopper protrusion 34 so as not to block the suction port 35 provided at the upper end of the stopper protrusion 34. Therefore, the pump type toothpaste container 3 of the present embodiment 3-1 sucks the toothpaste P at the suction port 35 provided at the side of the pump housing 31 and the end of the tube 40 at the same time and discharges the toothpaste P to the discharge port 21.

Therefore, in the pump type toothpaste container 2 of the present embodiment 3-1, the stopper projection 34 is provided inside the housing 31 of the air pump 30, the tube 40 is inserted into the lower end portion of the housing 31 and fixed to the lower portion of the stopper projection 34, and the suction port 35 is formed in the side surface of the housing 31, so that the toothpaste P can be sucked in simultaneously at the suction port 35 formed in the side surface of the pump housing 31 and the end of the tube 40. Therefore, when the viscosity of the toothpaste P is high, the toothpaste P is not used up only in the periphery of either side of the container 3, so that the pump is prevented from being driven empty and the toothpaste P can be stably discharged.

Referring to FIG. 5b, the tube 40 of example 3-2 is smaller in diameter than the tube 40 of example 3-1 described above. Specifically, since the diameter of the tube 40 of embodiment 3-2 is smaller than the diameter of the inside of the distal end portion of the housing 31, when the tube 40 is inserted into the housing 31, the tube 40 is not stopped by the stopper projection 34 and is further inserted, and the tube 40 is fixed in a state of being inserted into the inner wall of the lower end portion of the housing 31.

The tube 40 is inserted into and closely attached to the lower end of the valve provided in the housing 31 of the air pump 30. The tube 40 may block at least a part of one or more suction ports 35 provided at the upper end of the stopper protrusion 34. Therefore, the pump type toothpaste container 3 of the present embodiment 3-2 can suck the toothpaste P at the suction port 35 formed at the side of the pump housing 31 and the end of the tube 40 at the same time or suck the toothpaste P only at the end of the tube 40 and discharge it toward the discharge port 21.

In the pump type toothpaste container 3 of the present embodiment 3-2, the stopper projection 34 is provided inside the casing 31 of the air pump 30, but the tube 40 is inserted into the lower end portion of the casing 31 and fixed by being inserted between the inner walls of the casing 31, so that the opening and closing of the suction port 35 on the side surface of the casing 31 can be adjusted. Accordingly, when the viscosity of the toothpaste P is high, the toothpaste P can be sucked into the suction port 35 formed in the side surface of the pump housing 31 and the end of the tube 40 at the same time, and when the viscosity of the toothpaste P is low and the toothpaste P flows toward the lower end of the container, the toothpaste P can be sucked only into the end of the tube 40, thereby stably discharging the toothpaste P, as in example 3-1.

Thus, the pump type toothpaste container 3 of this embodiment 3 adjusts the suction position of toothpaste to that of embodiment 3-1 or 3-2 using one air pump 30 and pipes 40 having different diameters, thereby stably discharging toothpaste according to the viscosity of toothpaste.

Fig. 6 shows a pump type toothpaste container according to example 4 of the present invention, fig. 6a and 6b are sectional views of the pump type toothpaste containers according to examples 4-1 and 4-2, respectively, fig. 6c is a view showing an external appearance of a housing of the pump type toothpaste container according to example 4, and fig. 6d is a view enlarging the sectional view of the housing.

Referring to fig. 6, the pump type toothpaste container 4 according to embodiments 4-1 and 4-2 of the present invention includes a container body 10, a nozzle 20, an air pump 30 and a tube 40, and the housing 31 of the air pump 30 further includes a suction inlet 35.

The following description will mainly explain the differences between the present embodiments 4-1 and 4-2 and the above-described embodiments 3-1 and 3-2, and the portions not described may be replaced with the above-described ones.

Referring to fig. 6c and 6d, the lower end of the housing 31 has one or more suction ports 35 on the side surface to suck the toothpaste P into the air pump 30. Specifically, one or more suction ports 35 are provided at the upper end of the stopper projection 34 provided in the housing 31. The shape of the suction port 35 may be a circle or a quadrangle, but is not limited thereto.

The outer wall of the lower end of the housing 31 has an adsorption prevention rib 38, so that the suction port 35 can be prevented from being blocked by the narrowing of the inner layer 12. One or more suction prevention ribs 38 are provided on the outer wall of the housing 31, and the suction prevention ribs 38 are provided between the one or more suction ports 35. Alternatively, the plurality of adsorption preventing ribs 38 are formed on one suction port 35, and do not seal the suction port 35. For example, the adsorption preventing ribs 38 are vertically arranged on the suction port 35, so that even when the inner layers 12 are narrowed, the separation between the suction port 35 and the inner layers 12 can be ensured, and the toothpaste P can be smoothly sucked through the suction port 35.

Referring to fig. 6a, in embodiment 4-1, the tube 40 is inserted and fixed to the stopper protrusion 34 so as not to block the suction port 35 provided at the upper end of the stopper protrusion 34. Therefore, the pump type toothpaste container 4 of the present embodiment 4-1 can suck the toothpaste P at the suction port 35 formed at the side surface of the pump housing 31 and the end of the tube 40 at the same time and discharge the toothpaste P to the discharge port 21, and even if the inner layer 12 is narrowed, the separation between the suction port 35 and the inner layer 12 can be ensured, and the toothpaste P can be smoothly sucked through the suction port 35.

Referring to FIG. 6b, the tube 40 of example 4-2 has a smaller diameter than the tube 40 of example 4-1 described above. Specifically, since the diameter of the tube 40 of the embodiment 4-2 is smaller than the diameter of the inside of the distal end portion of the housing 31, when the tube 40 is inserted into the housing 31, the tube 40 is not inserted further by being stopped by the stopper projection 34, and the tube 40 is fixed so as to be inserted into the inner wall of the lower end portion of the housing 31.

The tube 40 is inserted into and closely attached to the lower end of the valve provided inside the housing 31 of the air pump 30. The tube 40 closes at least a part of one or more suction ports 35 provided at the upper end of the stopper projection 34. Therefore, the pump type toothpaste container 4 of the present embodiment 4-2 can suck the toothpaste P at the suction port 35 formed at the side of the pump housing 31 and the end of the tube 40 at the same time or suck the toothpaste P only at the end of the tube 40 and discharge it toward the discharge port 21.

In the pump type toothpaste container 4 of the present embodiment 4-2, the stopper projection 34 is provided inside the housing 31 of the air pump 30, but the opening and closing of the suction port 35 on the side surface of the housing 31 can be adjusted by inserting the tube 40 into the lower end portion of the housing 31 and fixing the tube between the inner walls of the housing 31. Accordingly, when the viscosity of the toothpaste P is high, the toothpaste P can be sucked into the suction port 35 formed in the side surface of the pump housing 31 and the end of the tube 40 at the same time, and when the viscosity of the toothpaste P is low and the toothpaste P flows toward the lower end of the container, the toothpaste P can be sucked only into the end of the tube 40, thereby stably discharging the toothpaste P, as in example 4-1.

In this way, the pump type toothpaste container 4 of this embodiment 4 adjusts the suction position of toothpaste to the embodiment 4-1 or 4-2 by one air pump 30 and by the tubes 40 having different diameters, and prevents the constriction of the suction port 35 by the inner layer 12 by the adsorption preventing rib 38, so that the toothpaste can be stably discharged according to the viscosity of the toothpaste.

Fig. 7 shows a pump type toothpaste container according to example 5 of the present invention, and fig. 7a and 7c are sectional views showing the pump type toothpaste containers according to examples 5-1 and 5-2, respectively. Fig. 7a and 7c show the air pump with the cap and nozzle removed to show the upper end of the air pump. Fig. 7b is a sectional view showing the air pump at the position of a hypothetical line AA 'shown in fig. 7a, fig. 7d is a sectional view showing the air pump at the position of a hypothetical line BB' shown in fig. 7c, and fig. 7e is an external appearance of the air pump.

Referring to fig. 7, the pump type toothpaste container 5 according to embodiments 5-1 and 5-2 of the present invention includes a container body 10, a nozzle 20, an air pump 30 and a tube 40.

The following description will mainly explain the differences between examples 5-1 and 5-2 and example 1, and the description thereof may be replaced with the above description.

The air pump 30 is coupled to the tube 40 through a lower end portion of the housing 31 forming an external appearance of the pump. Referring to fig. 7b and 7d, the inner wall of the lower end of the housing 31 has one or more 1 st ribs 33 protruding in the center direction.

Referring to fig. 7a, in example 5-1, the tube 40 is inserted through the lower end of the housing 31 until it reaches the lower end of the valve 37 and is fixed. However, the tube 40 is not closely attached to the lower end of the valve 37. Thereby, a space for communicating the toothpaste P is formed between the inner wall of the housing 31 and the tube 40. The shape of the 1 st rib 33 is not limited as long as it can prevent deformation of the housing 31 and can be used for coupling with the pipe 40. Specifically, the pipe 40 is inserted through the lower end portion of the housing 31 to the lower end portion of the valve 37, and is fixed in a state of being inserted into a space between the one or more 1 st ribs 33.

Referring to fig. 7b, the tube 40 is inserted and fixed in a state that one or more tubes 40 are inserted between the 1 st ribs 33 in the air pump 30. In this case, the inner wall of the air pump 30 and the tube 40 are disposed apart from each other by the 1 st rib 33. Therefore, the pump type toothpaste container 5 of the present embodiment 5-1 can suck the toothpaste P and discharge it toward the discharge port 21 at the same time in the space between the air pump 30 and the tube 40 and the distal end of the tube 40.

Referring to fig. 7c, in example 5-2, the diameter of the tube 40 is larger than the outer diameter of the lower end portion of the housing 31, and thus the air pump 30 is fixed in a state where at least a part thereof is inserted into the inner wall of the tube 40. The air pump 30 is inserted into the tube 40 until the tube 40 is located at the lower end of the valve 37.

Referring to fig. 7d, the shape of the 1 st rib 33 is not limited as long as it can prevent the deformation of the housing 31. The pump type toothpaste container 5 of this embodiment 5-2 sucks the toothpaste P at the distal end of the tube 40 and discharges it toward the discharge port 21.

Thus, the pump type toothpaste container 5 of the present embodiment 5 adjusts the suction position of toothpaste to the embodiment 5-1 or 5-2 by one air pump 30 and pipes 40 having different diameters, thereby stably discharging toothpaste according to the viscosity of toothpaste.

Fig. 8 shows a pump type toothpaste container according to example 6 of the present invention, and fig. 8a and 8c are sectional views of the pump type toothpaste containers according to examples 6-1 and 6-2, respectively. Fig. 8a and 8c are sectional views showing the cap and the air pump in order to show the upper end form of the air pump in detail, and fig. 8d shows a state where the air pump nozzle is removed at a position of a virtual line DD' shown in fig. 8 c. Fig. 8b is a sectional view showing the air pump at the position of a hypothetical line CC' shown in fig. 8a, and e is the appearance of the air pump.

Referring to fig. 8, the pump type toothpaste container 6 according to embodiments 6-1 and 6-2 of the present invention includes a container body 10, a nozzle 20, an air pump 30 and a tube 40.

The differences between the present embodiments 6-1 and 6-2 and the above-described embodiments 4-1 and 4-2 will be mainly described below, and the portions not described above may be replaced with those described above.

The air pump 30 may be combined with the tube 40 through a lower end portion of the housing 31 forming an external appearance of the pump. Referring to fig. 8b, 8d and 8e, at least one 2 nd rib 36 protruding from the surface is provided on the outer wall of the lower end portion of the housing 31. The housing 31 does not need to be provided with a suction port.

Referring to fig. 8a, in example 6-1, the tube 40 has a diameter larger than the outer diameter of the lower end portion of the housing 31, and is fixed in a state where at least a part of the air pump 30 is inserted into the inner wall of the tube 40. At this time, the one or more 2 nd ribs 36 protruding from the outer wall of the lower end portion of the housing 31 are fitted into the inner wall of the tube 40. The air pump 30 is inserted into the tube 40 until the tube 40 is located at the lower end of the valve 37. Thereby, a space for communicating the toothpaste P is formed between the outer wall of the air pump 30 and the inner wall of the tube 40.

Referring to fig. 8b, the outer wall of the air pump 30 and the tube 40 are disposed to be separated from each other by the 2 nd rib 36. Therefore, the pump type toothpaste container 6 of the present embodiment 6-1 can suck the toothpaste P and discharge it toward the discharge port 21 at the same time in the space between the air pump 30 and the tube 40 and the distal end of the tube 40.

Referring to fig. 8c, in example 6-2, the tube 40 is fitted into the lower end of the valve 37 through the lower end of the housing 31 and fixed. Specifically, the pipe 40 is fitted to the lower end of the valve 37 through the lower end of the housing 31, and is fixed so as to be inserted into the inner wall of the housing 31. Tube 40 is fitted to and closely attached to the lower end of a valve provided inside housing 31, and toothpaste P is supplied to air pump 30 only through tube 40.

Referring to fig. 8d, the shape of the 2 nd rib 36 is not limited as long as it is a shape that prevents deformation of the housing 31. The pump type toothpaste container 6 of this embodiment 6-2 sucks the toothpaste P only at the distal end of the tube 40 and discharges it toward the discharge port 21.

Thus, the pump type toothpaste container 6 of this embodiment 6 adjusts the suction position of toothpaste to that of embodiment 6-1 or 6-2 using one air pump 30 and pipes 40 having different diameters, thereby stably discharging toothpaste according to the viscosity of toothpaste.

Fig. 9 shows a pump type toothpaste container according to example 7 of the present invention, and fig. 9a is a sectional view of the pump type toothpaste container. Fig. 9a is a state in which the cap and the nozzle are removed in order to carefully show the form of the upper end portion of the air pump and the tube. Fig. 9b and 9c are a cross-sectional view of a pipe and a conceptual view showing a mode of manufacturing the pipe, respectively.

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

The air pump 30 is coupled to the tube 40 through a lower end portion of the housing 31 forming an external 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 air pump 30 can be inserted into the inner wall of the tube 40 and fixed.

Referring to fig. 9a and 9b, in embodiment 7, a tube 40 has a pair of suction ports 41 on its side surface to suck toothpaste P into the air pump 30.

Fig. 9c is a conceptual diagram illustrating a method of manufacturing the tube 40 of the present embodiment. The tube 40 may be manufactured by cutting a long tube with a tube cutter 50. In addition, at least one suction port 41 is formed in the pipe 40 by the suction port cutter 51. The suction port cutter 51 may be a blade having a shape having the outer diameter of the suction port 41, and the suction port 41 may be formed by punching the pipe 40. The manufacture of the pipe 40 by the pipe cutter 50 and the formation of the suction ports 41 by the suction port cutter 51 may be performed simultaneously or separately, and the suction port cutter 51 may form more than one pair of suction ports 41 in the pipe 40.

In embodiment 7, a tube 40 is inserted into and fixed to the lower end of the housing 31 in the pump type toothpaste container 7, and a suction port 41 is formed in the side surface of the tube 40, so that toothpaste P can be sucked into the suction port 41 and the end of the tube 40 at the same time. Therefore, when the viscosity of the toothpaste P is high, the toothpaste P is not used up only around either side of the container 7, and the pump can be prevented from being empty and from being insufficiently sucked. The tube 40 of the present embodiment is simply manufactured using a tube cutter 50 and a suction port cutter 51.

Next, examples of a high viscosity toothpaste composition used in the pump type toothpaste container according to the embodiment of the present invention will be described. The viscosity of the toothpaste composition of this example was 25,000 to 70,000cP, and although it was difficult to use it in a conventional deep tube pump type container, it was suitably used in the pump type toothpaste container of the present invention.

A toothpaste composition according to one embodiment of the present invention includes water, a thickener, an abrasive, and a polyol. 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, an air-bubbling agent, and the like, depending on the purpose of use.

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

Water may be included in an amount of 25 to 50% by weight, based on 100% by weight of the toothpaste composition. In the case of less than 25% by weight of water, the solubility of the toothpaste in the oral cavity is remarkably reduced, and the phenomenon of rapid sagging upon discharging the composition is serious, and in the case of more than 50% by weight, the shape-retaining function of the toothpaste is remarkably reduced.

The thickener can adjust the viscosity of the toothpaste composition to a viscosity suitable for loading into and discharging from the pump type toothpaste container of the present invention, i.e., 25,000 to 70,000 cP. 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 can be used. As the inorganic thickener, silica for thickening, soap clay, or the like can be used, and silica for thickening is preferably used.

The thickening silica may comprise precipitated silica or colloidal silica and may represent a BET specific surface area of 500m²More than g. The precipitated silica is prepared by mixing sand and caustic soda, dissolving in water, performing sol-gel reaction, and adding sulfuric acid, and is prepared to have a particle size of 500m by adjusting the sol-gel reaction time and conditions²(ii) a BET specific surface area of not less than g. The colloidal silica is prepared by spraying silicon tetrachloride and then burning. Since the thickening silica has a higher specific surface area than the polishing silica, it can absorb more water, and thus can increase the viscosity of the composition with time. In addition, silanol groups (-SiOH) included in the thickening silica exert a strong interaction by the adjacent silanol groups and hydrogen to improve the elasticity of the toothpaste and improve the shape-retaining function. The thickening silica is included in an amount of 0.1 to 8.0% by weight based on 100% by weight of the toothpaste composition. When 0.1 wt% or less of thickening silica is added, the shape-retaining function of the toothpaste cannot be improved, and when it is used in an amount exceeding 8 wt%, although the shape-retaining function can be improved, the discharge pressure is increased due to an excessive increase in viscosity, and thus the toothpaste cannot be discharged.

The cosolvent may aid in dissolving a substance having low solubility with respect to water, and as the cosolvent, a cosolvent used in toothpaste compositions in the art may be used. For example, there may be one or more selected from the group consisting of polyglycerol-3 methyl distearate, oleyl ether-10/polyethylene glycol 10 oleyl ether NF, glutethimide 10, PEG-8 laurate, cocamide MEA, polysorbate 60NF, polysorbate 60, polysorbate 80, isostearyl polyether-20, polysorbate 80NF, PEG-20 methylgluco-hemistearate, ceteareth-20, oleyl ether-20, steareth-21, linseed-20, poloxamer 184 and poloxamer 407, but not limited thereto.

The abrasive has a function of removing plaque in the oral cavity, and as the abrasive, an abrasive used in a toothpaste composition in the art can be used. For example, the inorganic filler may be one or more selected from the group consisting of hydrous silica, precipitated silica, calcium carbonate, polyethylene, cellulose, and zeolite, but is not limited thereto. To 100 wt% toothpaste, 5 wt% to 18 wt% abrasive is included. When the amount of the abrasive is 5 wt% or less, the sensation of slipping during rinsing due to the organic binder is reduced, and when the amount exceeds 18 wt%, the piston of the pump is worn, whereby the life of the pump is reduced and the discharge stability is reduced.

The polyol prevents wear of the nozzle and pump caused by the above abrasive in the toothpaste composition and prevents hardening from occurring in the discharge port in contact with air in the toothpaste container. As the polyol, polyols used in the art for toothpaste compositions can be used. For example, the solvent 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 includes at least one of liquid and solid polyols, and sorbitol can be used as the solid polyol. The polyol is included at 2 to 70 wt% with respect to 100 wt% of the toothpaste. The toothpaste composition of the present example was used by mixing liquid polyol and sorbitol, and sorbitol in solid powder was mixed in the form of an aqueous solution. The ratio of sorbitol (70% aqueous solution) to polyol is 1:0.1 to 1: 4. When the liquid and solid polyols are mixed and used in this manner, water is added to the solid polyol to combine the liquid polyol, thereby minimizing evaporation of water in the mixture and preventing a strong network from being formed between the polyols even if water is evaporated. Therefore, it is possible to solve the problem of hardening of the portion of the discharge port in contact with air in the toothpaste container when solid polyol is used alone.

The flavoring agent is left in the oral cavity to continuously emit flavor, and may be one or more selected from the group consisting of peppermint such as peppermint and spearmint, eugenol, methyl salicylate, wintergreen extract, melon extract, strawberry extract, and orange extract, but is not limited thereto.

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

The medicinal agent is added for oral hygiene, and can be used for preventing dental caries, recalcification, gingival diseases, tartar deposition, and whitening. As the drug-action agent used for the purpose of preventing dental caries, a compound which supplies fluoride ions such as sodium fluoride, sodium monofluorophosphate and tin fluoride can be used. Recalcification agents can also be used as caries prevention agents. Recalcification regenerates and restores hydroxyapatite, which is a main structural component of teeth, and uses a recalcification agent containing a divalent calcium cation or a phosphate anion to supply calcium ions and phosphate ions at the same time or to shift the chemical balance in the oral cavity to the side where hydroxyapatite is generated. For example, one or more selected from the group consisting of hydroxyapatite, calcium phosphate No. 2, calcium chloride, casein peptide, calcium glycerophosphate, sodium phosphate No. 1, sodium phosphate No. 2, sodium phosphate No. 3, potassium phosphate No. 1, potassium phosphate No. 2, and potassium phosphate No. 3 may be used. As the medicinal agent for preventing gum disease, isopropyl methylphenol, cyclohexadine, cetylpyridinium chloride, triclosan, xanthorrhizol and the like which exert bactericidal action against harmful microorganisms in the oral cavity can be used, and vitamins and enzymes, aminocaproic acid, allantoin and the like can be used for anti-inflammatory action of gums. Examples of the medicinal agents used for preventing deposition of tartar include sodium pyrophosphate, sodium acid pyrophosphate, potassium pyrophosphate, and sodium metaphosphate, and examples of the medicinal agents for achieving a whitening effect include hydrogen peroxide, carbodiimide peroxide, and calcium peroxide.

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

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

The foaming agent is added to facilitate the formation of foam when the toothpaste composition is used. For example, anionic surfactants selected from the group consisting of sodium laurate, sodium palmitate, sodium lauryl sulfate, potassium lauryl sulfate, POE-triethanolamine lauryl sulfate, POE-sodium lauryl sulfate, sodium lauroyl sarcosinate, and sodium N-myristoyl-N-methyltaurate; cationic surfactants such as octadecyl trimethyl ammonium chloride, dodecyl trimethyl ammonium chloride, cetyl pyridinium chloride, N' -dimethyl-3, 5-methylenepiperidine, alkyl quaternary ammonium salts, alkyl dimethyl benzyl ammonium salts, alkyl isoquinoline salts, dialkyl morpholine salts, benzalkonium chloride, and benzethonium chloride; amphoteric surfactants such as 2-undecyl-N, N, N- (hydroxyethylcarboxymethyl) -2-imidazoline sodium, 2-cocoyl-2-imidazoline hydroxide-1-carboxyethoxy disodium salt, 2-heptadecyl-N-carboxymethyl-N-hydroxyethylimidazoline betaine, lauryl dimethylaminoacetic acid betaine, alkyl betaine, and betaine; and sorbitol monooleate, sorbitol monoisostearate, sorbitan monolaurate, sorbitol monopalmitate, sorbitol monostearate, sesquisweet sorbitol, sorbitan trioleate, penta-2-ethylhexyl diglycerol sorbitan, tetra-2-ethylhexyl diglycerol sorbitan, monoglycerides, glycerol sesquioleate, glycerol monostearate, alpha, alpha' -pyroglutamic acid glycerol, glyceryl monostearate malic acid, POE-sorbitol monooleate, POE-sorbitol monostearate, POE-sorbitol tetraoleate, POE-sorbitan monolaurate, POE-sorbitan monooleate, POE-sorbitol, POE-almond monostearate, and other nonionic surfactants.

Additionally, the toothpaste composition of this example further comprises polyacrylic acid or a medically acceptable salt thereof. Polyacrylic acid is a polymer having elasticity by converting a functional group-COOH into-COO-under a hydrogen ion concentration of 4 to 10 to induce an electrostatic repulsive force. Polyacrylic acid has a very high elasticity as compared with polymers generally used in toothpastes, such as cellulose gum or xanthan gum. Thus, a toothpaste further comprising polyacrylic acid or its pharmaceutically acceptable salt is not only viscous but also elastic. The toothpaste composition further comprising polyacrylic acid or its pharmaceutically acceptable salt can improve the shape-retaining function of toothpaste, but has low fluidity at low viscosity to result in an increase in the margin, and thus is limited in use in a deep pump container, and is suitable for use in a pump type toothpaste container such as the above-described examples to provide a higher shape-retaining function.

0.2 to 1.5% by weight of polyacrylic acid or a pharmaceutically acceptable salt thereof is included with respect to 100% by weight of the composition. When polyacrylic acid or a pharmaceutically acceptable salt thereof is used in an amount of 0.2 wt% or less, the toothpaste cannot have an improved shape-retaining function, and when it is used in an amount exceeding 1.5 wt%, the viscosity increases together with the elasticity, and the discharge pressure is increased, resulting in a decrease in discharge stability.

When the toothpaste composition of this example was loaded into a pump type toothpaste container and sucked once to be discharged, the height of the block after 5 seconds of discharge was 0.7 to 0.95 of the diameter of the discharge port of the above pump type toothpaste container.

Preferred production examples of the present invention will be described in detail below.

Experimental example 1 viscosity of toothpaste composition

The toothpaste compositions prepared in the manufacturing examples and comparative examples were measured for initial viscosity value (cP) after 5 rotations at 20rpm using spindle nos. 5 to 7 using brookfield viscometer model RVT at 25 ℃. After the toothpaste composition was stored in a sealed state for 1 month, the viscosity value (cP) with time was measured by the same method, and the results are shown in table 3 below.

[ Table 3]

The toothpaste composition of the present production example includes thickening silica and has a high viscosity of 25,000cP or more based on the initial viscosity. In comparative examples 1 and 4 in which no thickening silica was used, a sufficient initial viscosity could not be secured, and in comparative example 3 in which a thickening silica was used in an excessive amount, the viscosity reached 100,000cP with time after 1 month, and it was difficult to discharge toothpaste by a pump.

Experimental example 2 discharge Property and remaining amount of each vessel

The toothpaste compositions prepared in the production examples and comparative examples were filled in a deep pump toothpaste container having a structure in which a deep tube was connected to a pump type toothpaste container (layered container) of example 2 of the present invention and a conventional air pump, and were discharged at a rate of 1 minute by a physical property tester (Texture Analyzer) (TA instrument) until the discharge was stopped, and thereafter, the discharge properties were evaluated, and the results thereof are shown in table 4 below.

Whether or not to discharge was evaluated based on the remaining amount after discharge being 30% of the entire filling amount, and in the case of 30% or more, it was evaluated that the toothpaste composition was not discharged from the container. In the case where the remaining amount exceeds 50%, the detection of the remaining amount is evaluated as meaningless. (good if discharged: remaining amount after discharge is less than 30%; poor if discharged is more than 30%)

[ Table 4]

The toothpaste compositions prepared in the production examples and comparative examples were stored in the container of example 2 and the deep pump toothpaste container for 1 month by the same method, and then the discharge property was evaluated by the same method, and the results are shown in table 5 below.

[ Table 5]

As shown in tables 4 and 5, the toothpaste composition of the present production example was excellent in the discharge property in the layered container of example 2 of the present invention at the time of the beginning and after 1 month, and showed a margin of 8% or less. The toothpaste compositions having the content ratios of sorbitol and polyhydric alcohol of production examples 11 to 16 were also excellent in the discharge property in the layered container, and showed a margin of 6% or less.

In comparative example 2, the use of polishing silica in place of thickening silica showed that the discharge was possible in the viscosity results, but the discharge stability was not good because the piston was worn. In comparative example 3, the thickening silica was used in an excessive amount, and the viscosity increased too much with time and could not be discharged by the air pump, and a large discharge pressure of 4kgf or more was also required for discharging the contents at the discharge port.

Experimental example 3 shape retaining function after discharging toothpaste composition

The toothpaste compositions prepared in the manufacturing examples and comparative examples were filled in the pump type toothpaste container of example 2 of the present invention and then sucked once to be discharged in a block form onto a graduated plastic plate.

After 5 seconds of discharge, the height of the block was detected and displayed as a ratio (height/diameter) to the diameter of the discharge port of the pump type toothpaste container, and the shape retaining function of the toothpaste block was evaluated. When the shape retaining function was 0.70 or more, the shape could not be retained or the bristles could not penetrate into the toothbrush even when the toothbrush was discharged, and therefore, the case of 0.70 or more was evaluated as good.

[ Table 6]

The toothpaste compositions of the present production examples and comparative example 3, which included thickening silica, exhibited excellent shape retention. The toothpaste compositions of comparative examples 1, 2 and 4 were inferior in shape-retaining function and were about to flow downward when discharged to a toothbrush for use. Comparative example 3 showed good shape retention, but the viscosity increased greatly and the discharge was not complete, and showed a high discharge pressure of 4kgf or more, and thus was not suitable for pumping toothpaste.

Experimental example 4 discharge stability caused by drying of discharge port after discharging toothpaste composition

The toothpaste compositions prepared in the manufacturing examples and comparative examples were filled in the pump type toothpaste container of example 2 of the present invention and then discharged by pumping once. The discharge stability was evaluated by measuring the discharge pressure and confirming whether the discharge port was clogged by re-pumping after leaving the toothpaste composition in the discharge port of the container at room temperature for 1 month. (discharge pressure evaluation:. smalle than 4kgf, X: 4kgf or more or discharge port clogging)

[ Table 7]

According to the compositions of production examples 11 to 16, the discharge port of the container was not clogged and the toothpaste composition using liquid and solid polyols or only liquid polyol was discharged. In the case of the toothpaste composition of comparative example 5, the discharge port of the container was blocked with the naked eye, and the discharge pressure was also 4kgf or more, thereby being evaluated as no discharge stability.
