Problems solved by technology

However, toothpaste in a dosage form with high elasticity flows downward relatively slowly, resulting in excessive toothpaste remaining in the container
In Japanese Patent Laid-Open Publication No. 2009-215176, as a countermeasure, a delamination toothpaste container including an outer layer forming an appearance and an inner layer for accommodating contents is disclosed, but when the toothpaste is actually discharged, the following problems occur: As the volume of the above-mentioned inner layer containing the toothpaste shrinks, the narrowing phenomenon in which the shrunk inner layer blocks the inlet of the container results in that a considerable amount of toothpaste stored cannot communicate with the pump dispenser and remains

experiment example 1

[0168] Experimental example 1. Viscosity of toothpaste composition

[0169] The toothpaste compositions prepared in the production examples and comparative examples were rotated 5 times at 20 rpm with a Brookfield viscometer RVT type using spindles 5 to 7 at 25° C., and the initial viscosity value (cP) was measured. After the toothpaste composition was sealed and stored for one month, the time-dependent viscosity value (cP) was measured by the same method, and the results are shown in Table 3 below.

[0170] [table 3]

[0171]

[0172] The toothpaste composition of this production example contains silicon dioxide for thickening and has a high viscosity of 25,000 cP or more based on the initial viscosity. In Comparative Examples 1 and 4, which did not use thickening silica, sufficient initial viscosity could not be secured. Compared with this production example, Comparative Example 3, which used an excessive amount of thickening silica, lost When the viscosity reaches 10...

[0173] Experimental example 2. Discharge performance and residual volume of each container

[0174] The toothpaste composition prepared in the manufacturing example and the comparative example is filled into the pump type toothpaste container (layered container) of the embodiment of the present invention 2 and the deep pump toothpaste container with the structure of the deep pipe connected in the conventional air pump, and The discharge performance was evaluated after discharging at a rate of once a minute using a Texture Analyzer (TA instrument) until no more discharge was performed, and the results are shown in Table 4 below.

[0175] Whether the toothpaste composition was discharged or not was evaluated on the basis that the remaining amount after the discharge was 30% of the entire filling amount, and when it was 30% or more, it was evaluated that the toothpaste composition was not discharged from the container. When the remaining amount exceeds 50%, it is evaluated that...

experiment example 3

[0185] Experimental Example 3. Shape retention function after discharge of toothpaste composition

[0186] The toothpaste composition prepared in the production example and the comparative example was filled in the pump-type toothpaste container of Example 2 of the present invention, pumped once, and discharged in a block form onto a graduated plastic plate.

[0187] 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 to evaluate the shape retention function of the toothpaste block. When the shape retaining function is 0.70 or more, even if it is discharged to the toothbrush, the shape cannot be maintained or the inside of the toothbrush bristles cannot be maintained, so the case of 0.70 or more is evaluated as good.

Abstract

The present invention relates to a pump-type toothpaste container and a toothpaste composition. The toothpaste composition is loaded in the pump-type toothpaste container. The pump-type toothpaste container is characterized by comprising: an outer layer which forms the external appearance of the container and is provided with a ventilation part; an inner layer that is disposed inside the outer layer and has a storage space in which a toothpaste composition is loaded; a nozzle having a discharge port through which the toothpaste composition is discharged; an air pump that sucks the toothpaste composition into the nozzle; and a tube for supplying the toothpaste composition loaded in the storage space to the air pump, the toothpaste composition including 1 to 5 wt% of silica for thickening and having a viscosity of 25,000 to 70,000 cP based on 100 wt% of the toothpaste composition.

Description

technical field [0001] 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 in which toothpaste contained in the container is sucked and discharged through a nozzle, and a toothpaste composition contained in the container. Background technique [0002] In general, paste-like toothpaste is put into a tube-shaped soft container and commercialized, and such a tube-shaped toothpaste container needs to be pressed with a strong force due to the high viscosity of the toothpaste depending on the situation. The problem of toothpaste extrusion, and the inconvenience that it is difficult to discharge the remaining toothpaste. [0003] Toothpaste mainly uses sorbitol as a humectant and humectant. As sorbitol, sorbitol in the state of about 70% aqueous solution is used, but it has a property of rapidly turning into a solid as water is dried. In particular, toothpaste...
