Description

Technical Field

[0001] This invention relates to cosmetics filled in a stacked peelable container. Background Technology

[0002] In recent years, various cosmetics that are waxy solids in their containers at room temperature but turn into emulsions or oily liquids when held in the hand have been sold in the fields of cleansing and massage cosmetics. These cosmetics were previously sold in so-called jars, and consumers would use tools such as spatulas to scoop them out of the jars, warm them in their hands, or mix and spread them by hand to make them into liquids before applying them to the face or other areas where makeup would be applied.

[0003] Consumers expect simpler and less cumbersome ways to use cosmetics, but the methods described above are complex, time-consuming, and tedious. Furthermore, cosmetics are often used in bathrooms and restrooms, where the containers sometimes occupy limited space. Additionally, the large openings of the containers increase the likelihood of water entering, making it difficult to maintain hygiene. Moreover, water ingress can impair the original function of the cleansing product.

[0004] As an easy method of removal, there are cosmetics filled in a container equipped with a pump, as described in Patent Document 1. With the cosmetic in Patent Document 1, the user presses a button, the pump draws the cosmetic from the container and sprays it out from the nozzle. Therefore, the user can quickly apply the cosmetic to the skin without using a spatula or similar tool, which is very convenient. Furthermore, because it does not have a large opening, the possibility of water or other substances entering is smaller compared to a jar container. However, in the case of cosmetics that are solid in the container, as described above, the container in Patent Document 1 relies solely on the suction force of the pump to draw out the contents. Therefore, the cosmetic cannot be fully liquefied and cannot be removed from the container.

[0007] Patent Document 1: Japanese Patent Application Publication No. 2013-139269 Summary of the Invention

[0008] (The problem the invention aims to solve)

[0009] To achieve the above-mentioned problem, the present invention provides a cosmetic material that is solid when no external force is applied, becomes liquid when external force is applied, and is filled in a stacked peeling container.

[0010] (Technical solution used to solve the problem)

[0011] The present invention is as follows.

[0012] <1> A cosmetic filling a stacked peelable container, wherein,

[0013] The aforementioned cosmetic material is solid when no external force is applied in the temperature range below its melting point, and becomes liquid when heated above its melting point or when an external force is applied.

[0014] <2> As mentioned above <1> The cosmetic filling the stacked peeling container, wherein the melting point is in the range of 40 to 80°C.

[0015] <3> As mentioned above <1> or <2> The cosmetic material filled in the stacked peeling container is, in which case, a cleansing cosmetic, a massage cosmetic, a cream, or a hair styling product.

[0018] The aforementioned receiving section and the aforementioned opening are composed of an outer layer and an inner layer, with the aforementioned cosmetic material filling the inner layer.

[0019] As the amount of cosmetic material decreases, the inner layer of the aforementioned receiving portion peels off from the outer layer and shrinks.

[0020] <6> As mentioned above <1> ~ <5> The cosmetic filling the stacked release container as described in any one of the following methods, wherein the stacked release container is a squeeze type or a pump type.

[0021] <7> As mentioned above <1> ~ <6> The method for manufacturing a cosmetic material filled in a stacked release container according to any one of the following methods, wherein the cosmetic material is heated to a temperature range above its melting point and filled into the stacked release container in a liquid state.

[0022] (Invention Effects)

[0023] According to the present invention, cosmetics filled in a stacked peel-off container are sprayed out as liquid from the opening by pressing the nozzle or squeezing the side of the container, thus allowing for easy removal in one step and improving ease of use. Furthermore, hygiene is ensured as water or air does not enter the container. In addition, cosmetics can be reliably used up without waste. Attached Figure Description

[0024] Figure 1 This is a cross-sectional view showing an example of an extrusion-type laminated peeling container that can be used in this invention.

[0025] Figure 2 express Figure 1 Instructions for using the stacked peeling container 1. Detailed Implementation

[0026] The embodiments of the present invention will be described below.

[0027] The cosmetic contents of this invention are non-flowable like a solid when no external force is applied, but become flowable after a certain external force is applied. Therefore, when the above-mentioned cosmetic in its solid state is picked up, its state changes to an oily or emulsified liquid by stirring it by hand or spreading it out.

[0028] When the cosmetic material described above is filled into a stacked peeling container as in this invention, it is solid when it is inside the container and no external force is applied, and it is liquid when it is sprayed out.

[0029] Furthermore, the cosmetic contents of the present invention are solid as described above when below their melting point, but become liquid when heated to above their melting point, similar to the case where external force is applied. Here, the melting point of the cosmetic varies depending on the amount of gelling agent such as polyethylene, and can therefore be adjusted to any temperature, but is preferably 40 to 80°C, more preferably 50 to 70°C, and even more preferably a temperature range of 55 to 65°C.

[0030] It should be noted that the viscosity of liquid cosmetics decreases as the temperature rises. Therefore, when filling a container with cosmetics, the viscosity can be adjusted by heating the cosmetics to the temperature range that displays the desired viscosity.

[0031] In this invention, "solid" refers to a state of aggregates of substances that can maintain a certain shape and volume and have properties that resist compression and deformation. In addition, solid is a state that displays a value of 200 or higher when measured using a rheometer (manufactured by RHEOTECH Co., Ltd.) under the following working conditions: (4) diameter of the adapter for viscosity: D10mm, falling speed 1mm / sec, and scale sensitivity of 100g.

[0032] Furthermore, in this invention, "liquid" refers to a state of matter that, while resistant to compression and possessing a certain volume, is virtually incapable of resisting deformation. A liquid is either completely non-viscous or, while viscous, exhibits fluidity.

[0033] As an embodiment of the present invention, the contents may be massage cosmetics.

[0034] The massage cosmetic material described above can use any ingredients as long as it meets the viscosity range mentioned above. It can contain oil as the main component and polyethylene as a gelling agent. In addition to the above-mentioned essential ingredients, depending on the purpose, within a qualitative and quantitative range without impairing the effect of the present invention, various raw materials commonly used in cosmetics, such as water, beauty ingredients, preservatives, pH adjusters, neutralizers, antioxidants, and fragrances, can also be added. The following describes a formulation example of the massage cosmetic material of the present invention.

[0035] <Examples of Massage Cosmetic Material Recipes>

[0036]

[0037] In another embodiment of the present invention, the contents may be a cleansing cosmetic.

[0038] The aforementioned cleansing cosmetic can use any ingredients as long as it meets the viscosity range described above. It may contain surfactants, oils as the main component, and polyethylene as a gelling agent. In addition to the aforementioned essential ingredients, depending on the purpose, and within a qualitative and quantitative range without impairing the effectiveness of the invention, various raw materials commonly used in cosmetics, such as water, beauty ingredients, preservatives, pH adjusters, neutralizers, antioxidants, and fragrances, may be added. The following describes a formulation example of the cleansing cosmetic of the present invention.

[0039] <Examples of Cleansing Cosmetic Material Formulations>

[0040]

[0041] As another embodiment of the present invention, the contents may be cream or hair styling product, but are not limited thereto.

[0042] The stacking and peeling containers include a squeeze type where the contents are ejected by squeezing the side of the container and pressing the nozzle to eject the contents. Both types of containers can be used as the stacking and peeling containers of the present invention.

[0043] A cross-sectional view of an example of a stacked peel container is shown in the figure. Figure 1The stacked peelable container 1 includes a container body 3 and a valve component 5. The container body 3 has an outer layer 11 and an inner layer 13 in a receiving section 7 and an opening 9. The outer layer 11 forms an outer shell 12, and the inner layer 13 forms an inner bag 14. Cosmetics are contained in the inner bag 14. As the cosmetics are reduced, the inner layer 13 peels off from the outer layer 11, thereby peeling the inner bag 14 off from the outer shell 12 and shrinking it. The opening 9 has an external threaded portion, on which a cap or pump with internal threads is mounted. The receiving section 7 has a body portion 19 with a substantially constant cross-sectional shape along its long side, and a shoulder portion 17 connecting the body portion 19 and the opening 9. The outer shell 12 has an external air inlet 15 in the receiving section 7, communicating between the intermediate space 21 and the external space. The external air inlet 15 is a through hole only provided in the outer shell 12 and does not reach the inner bag 14. The valve component 5 is inserted into the external air inlet 15.

[0044] As described above, the cosmetic material of the present invention is solid inside the container without external force, but becomes liquid when sprayed from the container by squeezing or pumping. The mechanism will be described in detail below using the accompanying drawings.

[0045] When using cosmetics packaged in a stacked peel-off container, such as Figure 2 As shown in (a) to (c), the product filled with cosmetic is tilted, and the outer casing 12 is held by the side and compressed to spray out the cosmetic. Initially, there is virtually no gap between the inner bag 14 and the outer casing 12. The compressive force applied to the outer casing 12 directly compresses the inner bag 14, thus compressing the inner bag 14 and spraying out the cosmetic. At this time, the inner bag 14 is compressed, thus the cosmetic as a whole is under pressure. Therefore, the intermolecular cross-links of the polyethylene formed in the oil phase are broken, and the solid cosmetic undergoes a state change to become liquid. As a result, the sprayed cosmetic is liquid.

[0046] The cap 23 has a built-in check valve (not shown) that allows the cosmetic material in the inner bag 14 to be sprayed out without allowing outside air to enter the inner bag 14. Therefore, if the compressive force applied to the outer shell 12 is released after the contents are sprayed out, the outer shell 12 will return to its original shape through its own restoring force, while the inner bag 14 remains contracted and only the outer shell 12 expands. Furthermore, as... Figure 2 As shown in (d), the intermediate space 21 between the inner bag 14 and the outer shell 12 is in a depressurized state, and outside air is introduced into the intermediate space 21 through the outside air inlet 15 formed in the outer shell 12. When the intermediate space 21 is in a depressurized state, the valve component 5 does not press against the outside air inlet 15, so it does not hinder the introduction of outside air.

[0047] Next, as Figure 2As shown in (e), when the side of the outer casing 12 is squeezed again for compression, the valve component 5 blocks the external air inlet 15, causing the pressure in the intermediate space 21 to increase. The compressive force applied to the outer casing 12 is transmitted to the inner bag 14 through the intermediate space 21. This compressive force causes the inner bag 14 to be compressed and the cosmetic material to be sprayed out. At this time, the inner bag 14 is compressed and the cosmetic material as a whole is under pressure, so the cosmetic material becomes liquid.

[0048] After the contents are ejected, such as Figure 2 As shown in (f), if the compressive force applied to the outer shell 12 is released, the outer shell 12 will introduce the outside air into the intermediate space 21 through the outside air inlet 15, and at the same time restore its original shape by its own restoring force.

[0049] As described above, since the inner layer shrinkage is reduced as the cosmetic material decreases, the cosmetic material of the present invention also has the following advantages: it is less likely that cosmetic material will remain in the corner of the container and cannot be discharged, and it can be used until the end without causing waste.

[0050] The present invention will be further described in detail below with reference to the embodiments, but the present invention is not limited to these embodiments.

[0051] Example

[0052] First, weigh (i) 93.9 parts by weight of olive oil and (ii) 6.0 parts by weight of polyethylene (molecular weight approximately 500) into a stainless steel container. Heat the mixture to 80–90°C using hot water, steam, or an oil bath, and mix. After thorough mixing, allow the mixture to cool to below 70°C. Then, add (iii) 0.1 parts by weight of vitamin E oil (antioxidant) and mix to create a massage cosmetic.

[0053] The massage cosmetic material manufactured using the above method was cooled to 70°C and then poured into a stacked peeling container for filling. It was then allowed to cool and stand. Three types of stacked peeling containers were used: a pump-type container with a capacity of 50 mL, a pump-type container with a capacity of 300 mL, and a squeeze-type container with a capacity of 100 mL. As a comparative example, a general pump container with a capacity of 300 mL without a peeling structure was used.

[0054] The ejection state of cosmetics completely solidified and packed in a stacked release container was tested. A case where the product was ejected as a liquid regardless of the container's contents was rated ○; a case where the product was ejected as a liquid but in insufficient quantity, or partially ejected as a solid, or where the state of the ejected product changed depending on the container's contents was rated △; and a case where no product was ejected at all was rated ×. The results are shown in Table 1.

[0055] Table 1

[0057] For stacked stripping containers, both pump-type and extrusion-type containers produce a liquid ejection. For general pump containers, the contents are not ejected. In general extrusion containers (tube containers), the contents are initially ejected as a liquid (emulsion) similar to stripping containers. However, during repeated pressurization of the entire tube, the liquid is subjected to pressure, and its viscosity decreases with each pressurization, eventually leading to liquefaction, making it unsuitable for practical use. Furthermore, the reduction of liquid inside the tube creates space, preventing complete and efficient drainage, which is another reason for its unsuitability for practical use.

[0058] (Industrial applicability)

[0059] This invention relates to a cosmetic material that is filled in a stacked release container, and is solid at room temperature without external force, but becomes liquid when external force is applied. Furthermore, it is also believed that using a stacked release container can achieve the same effect for compositions exhibiting the same state change, such as pharmaceuticals, beverages, food products, coatings, and other industrial products.
