Description

[Technical Field]

[0001] The present invention relates to a cosmetic container for storing liquid cosmetics such as mascara, eyebrow pencils, etc. (hereinafter referred to as "liquid cosmetics"). [Background technology]

[0002] In recent years, with the SDGs (indicators for realizing a sustainable world), environmental issues, and the ECO boom, there is a demand for resource conservation, such as resource recycling, in various situations and products. Therefore, attempts are being made to recycle the above-mentioned cosmetic containers as much as possible (see Patent Document 1).

[0003] Incidentally, in the above-mentioned cosmetic container, if each of the parts that make up the cosmetic container, such as the cosmetic container body, the cap that holds the applicator body firmly inside, and the squeezer, are made of a single material, the cosmetic container can be recycled all at once without having to be separated or sorted by material.

[0004] However, in recent years, the components that make up cosmetic containers are made of various materials. Therefore, the cap, applicator body, and cosmetic container body are made of hard resins so that they can adequately withstand external stress or stress applied during application, and the squeezer is made of soft resin so that it can be deformed to fit the shape of the applicator body.

[0005] Therefore, when each component of the cosmetic container is made of a different material, it is necessary to separate the components by material when the cosmetic container is recycled. For this separation, a method using underwater specific gravity separation is adopted, which allows for simple and accurate separation of the components all at once.

[0006] Here, for each of the components that make up the cosmetic container, for example, the hard resins generally used for the cap, applicator, and cosmetic container body usually have a specific gravity of 1 or more, while various materials are used for the soft resins used for the squeezer, and soft resins with a specific gravity of 1 or more are sometimes used.

[0007] Therefore, when applying the underwater specific gravity separation method to the recycling of cosmetic containers, if the specific gravity of the soft resin that forms the above-mentioned squeezed material is 1 or more, it will be similar to the specific gravity of the hard resin that forms the cap, applicator body, and cosmetic container body, making it impossible to easily and accurately separate and separate the two together. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-191430 Summary of the Invention [Problem to be solved by the invention]

[0009] Therefore, in recycling cosmetic containers made up of parts made of hard or soft resin, the mixture of each part fragment obtained by finely crushing each part that makes up the cosmetic container can be easily and accurately separated all at once using an underwater specific gravity separation method, allowing the two to be accurately separated. [Means for solving the problem]

[0010] The first feature is, The container is comprised of a cap that holds the applicator body integrally therein, and a cosmetic container body to which the cap is detachable and which contains a liquid cosmetic material therein; The applicator body fixed integrally to the cap has a comb at one end of a comb shaft and a base portion at the other end that is larger in diameter than the comb shaft and fits into the cap; The cosmetic container body has an opening at the tip for attaching a scrubber, The cap, the applicator, and the cosmetic container body are made of a single material of the same quality and with a specific gravity of 1 or more, The squeegee is made of a single material that is different from the cap, the applicator, and the cosmetic container body and has a specific gravity of less than 1; And the second characteristic is, The container is comprised of a cap that holds the applicator body integrally therein, and a cosmetic container body to which the cap is detachable and which contains a liquid cosmetic material therein; The applicator body fixed integrally to the cap has a tip at one end of a shaft and a base portion at the other end that is larger in diameter than the shaft and fits into the cap; The cosmetic container body has an opening at the tip for accommodating a sleeve and a straw, The cap and the cosmetic container body are made of a single material of the same quality and with a specific gravity of 1 or more, The applicator and sleeve are made of a single or multiple material with a specific gravity of less than 1, The squeegee is made of a single material that is different from the applicator body and the sleeve and has a specific gravity of less than 1, Based on the first or second feature, the third feature is The single or multiple materials constituting the cap and the cosmetic container body are of the same quality and have a specific gravity of 1 or more, and are made of polyethylene terephthalate (hereinafter referred to as "PET") alone or in combination with PET, The above-mentioned applicator and sleeve are made of a single or multiple material with a specific gravity of less than 1, The above-mentioned squeezer is made of a material different from the applicator or sleeve, and is made of a single material, synthetic rubber (hereinafter referred to as "NBR") with a specific gravity of less than 1, or PP (i.e., "polypropylene"; the same applies hereinafter), or PE (i.e., "polyethylene"; the same applies hereinafter).

[0011] Therefore, when recycling the above-mentioned cosmetic container, each part made of different materials that constitutes the cosmetic container is finely crushed together, and the mixture of finely crushed parts is further separated into materials using the underwater specific gravity separation method, resulting in the following: That is, the cap and the cosmetic container body are made of a material such as a hard resin with a specific gravity but Since the specific gravity is 1 or more, the material of the squeezer, applicator, and sleeve is soft resin, for example, and the specific gravity is less than 1, so the material floats in water. As a result, the mixture of component pieces obtained by finely crushing each component that makes up the cosmetic container can be easily and accurately separated into the component pieces that make up the cap, applicator, cosmetic container body, and even the sleeve and squeezer, allowing the two to be accurately separated by material. Therefore, the cap and the cosmetic container body made of PET alone or in combination with PET, which is a hard resin, can be recycled. The soft resin material can be used not only for application parts such as scrapers and tips, but also for gaskets that are deformably sandwiched between the cap and the cosmetic container body to which the cap is attached or detached, particularly the opening, so as to maintain sufficient airtightness within the cosmetic container body. [Effects of the Invention]

[0012] The present invention is effective in recycling cosmetic containers made up of parts made of different materials by crushing the cosmetic container into small pieces all at once and separating the mixture into individual parts by underwater gravity separation. Since the hard resin that makes up the cap and cosmetic container body has a specific gravity of 1 or more, and the soft resin that makes up the strainer, applicator, and sleeve has a specific gravity of less than 1, the two can be easily and accurately separated by their specific gravity, and the two can be accurately separated by material, resulting in the excellent effect of allowing only the necessary materials to be recycled.

[0013] In this case, when separating the cosmetic containers for recycling, it is sufficient to crush the cosmetic containers into small pieces all at once, which has the excellent effect of sufficiently improving the efficiency of the recycling work and reducing the work costs. [Brief explanation of the drawings]

[0014] [Figure 1] FIG. 1 is a longitudinal cross-sectional view of a main part of a cosmetic container according to a first embodiment of the present invention. [Figure 2] FIG. 2 is a longitudinal sectional view of a main part of a cosmetic container according to a second embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0015] To this end, the materials that make up each component of the cosmetic container, i.e., the cap and the cosmetic container body, are made of the same type of hard resin with a specific gravity of 1 or more, while the materials that make up the squeezer, applicator, and sleeve are made of a single or multiple soft resins with a specific gravity of less than 1. [Example]

[0016] FIG. 1 shows a cosmetic container 1 according to a first embodiment of the present invention, which is composed of a cap 2 and a cosmetic container body 4 to which the cap 2 is detachable.

[0017] The cap 2 constituting the cosmetic container 1 holds the applicator body 3 integrally therein, and the applicator body 3 has a comb 3b at one end of a comb shaft 3a and a base portion 3c at the other end that is larger in diameter than the comb shaft 3a and fits into the cap 2.

[0018] Furthermore, the cosmetic container body 4 constituting the cosmetic container 1 contains a liquid cosmetic 4a therein and has an opening 4b that leads to the interior containing the liquid cosmetic 4a, and a squeezer 5 is attached within the opening 4b.

[0019] Furthermore, the cap 2, applicator body 3, and cosmetic container body 4 that constitute the cosmetic container 1 in Example 1 above are made of a hard resin with a specific gravity of 1 or more, and the squeezer 5 is made of a soft resin of a different material from the cap 2, applicator body 3, and cosmetic container body 4, with a specific gravity of less than 1.

[0020] Here, examples of modified examples of the components constituting the cosmetic container 1 according to the first embodiment are as follows. For example, in variant 1, the cap 2 constituting the cosmetic container 1, the applicator 3 consisting of the comb shaft 3a including the comb 3b, and the cosmetic container body 4 are made of PET (specific gravity 1.3 to 1.4), which is a hard resin, and the squeezer 5 is made of NBR (specific gravity less than 1), which is a soft resin. In a further variation example 2, the cap 2 and the cosmetic container body 4 constituting the cosmetic container 1 are made of the hard resin PET (specific gravity 1.3 to 1.4), the comb shaft 3a including the comb 3b of the applicator body 3 is made of the hard resin PP (specific gravity 0.9), and the squeezer 5 is made of the soft resin NBR (specific gravity less than 1).

[0021] As described above, in recycling the cosmetic container 1 according to Example 1, the mixture of component pieces obtained by finely crushing the cosmetic container is separated into materials by underwater gravity separation as follows.

[0022] That is, the cap 2, applicator body 3, and cosmetic container body 4 that make up the cosmetic container 1 are all made of the same material, i.e., hard resin, and will sink in water because their specific gravity is 1 or more. In addition, the squeezer 5 is made of soft resin, and its specific gravity is less than 1, so it will float in water. As a result, the mixture of each component piece that makes up the cosmetic container 1 is easily and accurately separated in water into the hard resin cap 2, applicator body 3, and cosmetic container body 4 components and the soft resin squeezer 5 components, depending on the specific gravity of each component piece, and the two components can be accurately separated. In the cosmetic container 1 of Modification 1 of Example 1, the applicator 3 and cosmetic container body 4, which are made of PET (specific gravity 1.3 to 1.4), including the cap 2 and comb shaft 3a including the comb 3b, can be easily and accurately separated from the scraper 5, which is made of NBR (specific gravity less than 1). In addition, in the cosmetic container 1 of Modification 2, the applicator 3, which is made of PET (specific gravity 1.3 to 1.4), including the cap 2 and cosmetic container body 4, and comb shaft 3a including the comb 3b, which is made of PP (specific gravity 0.9), can be easily and accurately separated from the scraper 5, which is made of NBR (specific gravity less than 1).

[0023] Therefore, in the cosmetic container 1, which is the first modified example of the first embodiment described above, the applicator body 3 and the cosmetic container body 4, which are made of the hard resin PET, the cap 2, and the comb shaft 3a including the comb 3b, and the scraper 5, which is made of the soft resin NBR, can be easily and accurately separated by underwater specific gravity separation, and since both can be accurately separated, the applicator body 3 and the cosmetic container body 4, which are made of the PET, the cap 2, and the comb shaft 3a including the comb 3b, can be recycled. Furthermore, in the cosmetic container 1 of variant example 2, the cap 2 and cosmetic container body 4, which are made of hard resin PET, and the applicator body 3 consisting of the comb shaft 3a including the comb 3b, which is made of PP, and the squeezer 5, which is made of soft resin NBR, can be easily and accurately separated by underwater specific gravity separation, and since both can be accurately separated, the PET can be recycled. [Example]

[0024] FIG. 2 shows a cosmetic container 1' according to a second embodiment of the present invention, which comprises a cap 2' and a cosmetic container body 4' to which the cap 2' is detachable.

[0025] The cap 2' constituting the cosmetic container 1' holds the applicator body 3' integrally therein, and the applicator body 3' has a tip 3b' at one end of the applicator shaft 3a' and a base portion 3c' at the other end that is larger in diameter than the applicator shaft 3a' and fits into the cap 2'.

[0026] Furthermore, the cosmetic container body 4' constituting the cosmetic container 1' contains a liquid cosmetic 4a' inside and has an opening 4b' that leads to the interior containing the liquid cosmetic 4a', and a squeezer 5' is attached inside the opening 4b' while a sleeve 4c' prevents the cosmetic 4a' from coming out.

[0027] Furthermore, the cap 2' and the cosmetic container body 4' constituting the cosmetic container 1' in Example 2 above are made of a hard resin having a specific gravity of 1 or more, the applicator 3' and the sleeve 4c' are made of a hard resin having a specific gravity of less than 1, and the squeezer 5' is made of a soft resin that is a different material from the applicator 3' or the sleeve 4c' and has a specific gravity of less than 1.

[0028] Here, the following are examples of modified examples of the components constituting the cosmetic container 1' according to the second embodiment. For example, in variant example 1, the cap 2', applicator 3', cosmetic container body 4' and sleeve 4c' that make up the cosmetic container 1' are made of PET (specific gravity 1.3 to 1.4), a hard resin, and the squeezer 5' is made of NBR (specific gravity less than 1), a soft resin. In variant 2, the cap 2' and the cosmetic container body 4' that constitute the cosmetic container 1' are made of PET (specific gravity 1.3 to 1.4), which is a hard resin, and the applicator shaft 3a' and tip 3b' are made of PP (specific gravity 0.9), which is a hard resin, and the squeezer 5' is made of NBR (specific gravity less than 1), which is a soft resin. Furthermore, in variant example 3, the cap 2', the applicator shaft 3a' of the applicator body 3', and the cosmetic container body 4' that constitute the cosmetic container 1' are made of PET (specific gravity 1.3 to 1.4), and the squeezer 5' and tip 3b' are made of NBR (specific gravity less than 1), a soft resin. In addition, as a fourth variant, if metal is used for part of the applicator body 3' that is fixed integrally to the cap 2', such as in the case of mascara, the cap 2' itself cannot be recycled, but the cosmetic container body 4' including the sleeve 4c' is made of PET (specific gravity 1.3 to 1.4), which is a hard resin, and the squeezer 5' is made of NBR (specific gravity less than 1), which is a soft resin.

[0029] As described above, when recycling the cosmetic container 1' according to Example 2, the mixture of each component piece obtained by finely crushing the cosmetic container 1' is separated into materials using the underwater specific gravity separation method as follows.

[0030] That is, the cap 2' and the cosmetic container body 4' constituting the cosmetic container 1' according to Example 2 are made of the same material, i.e., hard resin, and will sink in water because their specific gravity is 1 or greater. Also, the applicator body 3', sleeve 4c', and squeezer 5' are made of hard or soft resin, and will float in water because their specific gravity is less than 1. As a result, the mixture of each component part constituting the cosmetic container 1' is mixed in water by the specific gravity of each component part, and the hard resin cap 2', the component part of the cosmetic container body 4', coating The fabric body 3', the sleeve 4c', and the soft resin squeezer 5' are easily and accurately separated, and the two are accurately separated. Furthermore, in the cosmetic container 1' of variant 1 of Example 2, the hard resin PET (specific gravity 1.3 to 1.4) that forms the cap 2', the applicator body 3' including the comb 3b', the sleeve 4c' and the cosmetic container body 4', and the soft resin NBR (specific gravity less than 1) that forms the squeezer 5' can be easily and accurately separated, and the two can be accurately separated. Furthermore, in the cosmetic container 1' of variant example 2, the cap 2' and cosmetic container body 4', which are made of PET, can be easily and accurately separated from the applicator shaft 3a', tip 3b', which are made of hard resin PP (specific gravity 0.9), and strainer 5', which is made of soft resin NBR (specific gravity less than 1), allowing the two to be accurately separated. In the cosmetic container 1' of variant example 3, the cap 2', cosmetic container body 4', and applicator shaft 3a' that make up the cosmetic container 1' are made of a hard resin, PET (specific gravity 1.3 to 1.4), and the squeezer 5' and tip 3b' are made of a soft resin, NBR (specific gravity less than 1), which can be easily and accurately separated, allowing the two to be accurately separated. In addition, the cosmetic container 1' of variant example 4 cannot be recycled because metal is used in part of the applicator body 3' that is held integrally by the cap 2'. However, it can be easily and accurately separated into the hard resin PET (specific gravity 1.3 to 1.4) that makes up the cosmetic container body 4, including the sleeve 4c', and the soft resin NBR (specific gravity less than 1) that makes up the squeezer 5', and the two can be accurately separated.

[0031] Therefore, in the cosmetic container 1' in the variant 1 of the above-mentioned Example 2, the cap 2', the comb shaft 3a' including the comb 3b', and the cosmetic container body 4, which are made of hard resin PET, and the strainer 5', which is made of soft resin NBR, can be easily and accurately separated by underwater specific gravity separation, and the two can be accurately separated, allowing the PET to be recycled. Furthermore, in the cosmetic container 1' of variant 2, the cap 2', applicator shaft 3a', and cosmetic container body 4', which are made of hard resin PET, can be easily and accurately separated by underwater specific gravity separation, from the squeezer 5', which is made of soft resin NBR, and the tip 3b', which is made of PP, and the two can be accurately separated and the PET can be recycled. In the cosmetic container 1' of variant example 3, the cap 2', cosmetic container body 4, and applicator shaft 3a' that make up the cosmetic container 1', which are made of hard resin PET, can be easily and accurately separated by underwater specific gravity separation, from the squeezer 5', which is made of soft resin NBR, and the tip 3b', which is made of hard resin, and the two can be accurately separated and the PET can be recycled. In addition, in the cosmetic container 1' of variant example 4, metal is used in part of the cap 2', making it impossible to recycle, but it can be easily and accurately separated into the cosmetic container body 4', including the sleeve 4c' made of hard resin PET, and the squeezer 5' made of soft resin NBR, and by accurately separating the two, the PET can be recycled.
