Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the gas barrier property of the container body is not always sufficient, and oxygen gradually permeates through the container body over a long period from the time the product is completed until the user opens it, and the contents tend to deteriorate. Also, even in a container body in which oxygen permeation is blocked by laminating a metal film, oxygen may flow into the container body through the gap generated between the container body and the lid, and the active ingredient may deteriorate.

[0005] An object of the present invention is to provide a package that can stably hold contents such as cosmetics containing an active ingredient that is easily deteriorated by oxygen adsorption for a long period of time.

Embodiments for Carrying Out the Invention

[0015] Hereinafter, embodiments of the package of the present invention will be described, but the present invention is not limited thereto. In addition, the drawings may be schematically simplified for the purpose of explaining the content of the invention, and the ratio of the drawn components or the dimensions between the components may not match the ratio of those dimensions described in the specification. In addition, components described in the specification may be omitted in the drawings, or the number may be omitted in the drawing.

[0016] (Package) The package according to an embodiment of the present invention will be described with reference to FIG. 1. The package 1 includes a content 10 containing a predetermined component, an inner container 20 that houses the content 10, an oxygen adsorbent 50, and a bag body 60 that hermetically houses these.

[0017] (Content)<0​​​​Vitamin A compounds such as retinol are substances that exert various physiological effects, and are known, for example, as cosmetic ingredients that show wrinkle-improving effects. Commonly known retinol derivatives include retinyl palmitate, retinyl acetate, silussphere retinol, and tocopheryl retinoic acid.

[0019] Vitamin C derivatives such as ascorbic acid are substances that exert various physiological effects. For example, they have cellular respiration, enzyme activation, and collagen formation effects due to their strong reducing action, and they also have a melanin-reducing effect. Derivatives of ascorbic acid and their salts are not particularly limited and include, but are not limited to, alkali metal salts of ascorbic acid, earth metal salts of ascorbic acid, methyl or ethyl esters of ascorbic acid, isoascorbic acid, alkali metal salts of isoascorbic acid, earth metal salts of isoascorbic acid, and methyl or ethyl esters of isoascorbic acid. Ascorbic acid may be in L-form or D-form.

[0020] The properties of the contents are not particularly limited and may be, for example, liquids, creams, gels, solids, or mixtures thereof. Furthermore, the uses of the contents are not particularly limited and may include, for example, cosmetics, pharmaceuticals, food products, and beverages.

[0021] (Inner container) The inner container 20 holds the contents 10. The inner container 20 can be of any form as long as it can hold the contents 10.

[0022] The inner container 20 can be, for example, a pouch container. Examples include a sealed bag type with sealed sides, a standing pouch type with a boat-shaped bottom that allows it to stand on its own, and a foldable bag shape such as a gusseted type with gussets on the sides or bottom.

[0023] Furthermore, the inner container 20 can be configured to include a container body 30 and a lid 40.

[0024] (Container body) The container body 30 is not particularly limited as long as it can hold the contents 10, but considering ease of removal and storage of the contents containing the active ingredient, it is preferable that it be one of a bottle container body, a tube container body, a jar container body, or a dispensing container body.

[0025] (Lid) The lid 40 seals the container body 30 containing the contents 10. Here, the lid 40 is not limited to a cap, but refers to any component that closes the opening of the container body 30 containing the contents 10, such as a sealing film or a dispenser pump. Figure 1 shows a configuration in which a cap, serving as a lid 40, is attached to the tube container body, which is the container body 30.

[0026] (Oxygen adsorbent) The oxygen adsorbent 50 is not particularly limited as long as it has the function of adsorbing oxygen, and known oxygen adsorbents such as inorganic oxygen adsorbents such as iron-based, zinc-based, and hydrosulfite-based, and organic oxygen adsorbents such as ascorbic acid-based, polyhydric alcohol-based, and activated carbon-based can be used, but it is preferable to use an iron-based oxygen adsorbent because it is safe and readily available.

[0027] (Bag body) The bag 60 seals and contains contents 10 containing predetermined components, a container body 30 containing the contents 10, a lid 40 that seals the container body 30, and an oxygen adsorbent 50.

[0028] Examples of the bag shape 60 include a sealed bag type with sealed sides, a standing pouch type with a boat-shaped bottom that allows it to stand on its own, and a foldable bag shape such as a gusseted type with gussets on the sides or bottom.

[0029] The bag 60 is preferably made of a synthetic resin film with a silica vapor-deposited film, an alumina vapor-deposited film, or an aluminum vapor-deposited film formed thereon, or of a laminated film with an aluminum foil layer and a synthetic resin layer formed thereon, in order to suppress oxygen permeation.

[0030] (Placement of oxygen adsorbent) The oxygen adsorbent 50 can be placed inside the container body 30 sealed by the lid 40, for example by attaching it to the inside of the lid 40, but it can also be placed outside the container body 30 sealed by the lid 40, that is, outside the inner container 20.

[0031] By placing the oxygen adsorbent 50 on the outside of the inner container 20, the oxygen adsorbent 50 can adsorb oxygen in the inner container 20 along with the space inside the bag 60, thereby maintaining the content of the active ingredients in the contents 10 stably for an even longer period of time.

[0032] The amount of oxygen adsorbent to be added is preferably an amount that can adsorb more oxygen than or equal to the amount of oxygen in the space within the bag 60 and in the inner container 20. [Examples]

[0033] [Retinol quantitative test] As shown in Table 1, various packaging materials were prepared with different specifications for the container body and lid, the presence or absence of an oxygen adsorbent, and the presence or absence and specifications of a bag. A formulation containing 3000 ppm of retinol was filled into the inner container of each packaging material, and quantitative tests of retinol were performed using these samples. Furthermore, the oxygen adsorbent contained within the bag was placed on the outside of the inner container.

[0034] For each sample, the amount of retinol was quantified before the start of the test, and then the amount of retinol remaining from the initial stage (%) was calculated by quantifying the retinol after 1 month (1M) under conditions of 50°C (Figure 2).

[0035] The evaluations shown in Table 1 are based on the following criteria. An A or B rating indicates a pass, while a C or D rating indicates a fail. <Evaluation Criteria> A: Remaining amount is 90% or more B: Remaining amount is 80% or more but less than 90% C: Remaining amount is 60% or more but less than 85% D: Remaining amount is less than 60%

[0036] [Table 1]

[0037] As shown in Table 1, test examples 4, 7, 9, 11, and 13, in which the inner container and oxygen adsorbent were placed inside the bag, all showed favorable results.

[0038] Next, using a formulation containing 500 ppm of retinol, we added samples in which argon gas was introduced into the upper space of the inner container after filling to reduce the oxygen concentration inside the container, and samples in which the amount of contents filling the inner container was halved to create a larger upper space. We then conducted quantitative retinol tests on each of these samples. For each sample, the amount of retinol was quantified before the start of the test, and then the amount of retinol remaining from the initial stage (%) was calculated by quantifying the retinol after 1 month (1M) under conditions of 50°C (Figure 3).

[0039] Table 2 shows the contents of each sample, including the specifications of the inner container, the presence or absence of oxygen adsorbent, the presence or absence of a bag, the amount of contents filled, and whether or not argon gas was replaced inside the inner container, as well as the evaluation of the remaining amount of retinol in each sample. Furthermore, the oxygen adsorbent contained within the bag was placed on the outside of the inner container.

[0040] The evaluations shown in Table 2 are based on the following criteria. An A or B rating indicates a pass, while a C or D rating indicates a fail. <Evaluation Criteria> A: Remaining amount is 90% or more B: Remaining amount is 80% or more but less than 90% C: Remaining amount is 60% or more but less than 85% D: Remaining amount is less than 60%

[0041] [Table 2]

[0042] As shown in Table 2, test examples 25, 28, and 31, in which the inner container and oxygen adsorbent were placed inside the bag, all showed favorable results.

[0043] Furthermore, the results from test examples 25, 28, and 31 confirmed that the packaging according to the present invention can stably retain the active ingredients for a long period of time without introducing an inert gas such as argon gas.

[0044] Next, a container body sealed with a lid and an oxygen adsorbent were placed inside a pouch container made of silica vapor-deposited film, and the oxygen concentration inside the container body was measured after 1 week (1W) to 8 weeks (8W).

[0045] [Table 3]

[0046] As shown in Table 3, it was confirmed that the oxygen concentration inside the container body gradually decreased in a package containing a container body sealed with a lid inside a pouch container and an oxygen adsorbent sealed on the outside of the container body.

[0047] According to the packaging 1 of this embodiment described above, for example, the following effects can be achieved.

[0048] The packaging body 1 comprises a contents 10 containing at least one selected from the group consisting of retinol, retinol derivatives, ascorbic acid, ascorbic acid derivatives, and salts thereof; an inner container 20 containing the contents 10; an oxygen adsorbent 50; and a bag 60 in which the contents 10, inner container 20, and oxygen adsorbent 50 are sealed and contained.

[0049] With this configuration, the oxygen adsorbent 50 adsorbs oxygen in the inner container 20, allowing the content of active ingredients such as retinol to be maintained stably for a long period of time. Furthermore, this eliminates the need to introduce an inert gas into the bag 60 or the inner container 20 to lower the oxygen concentration, as was done in the past.

[0050] Inside the bag 60, the oxygen adsorbent 50 was placed on the outside of the inner container 20.

[0051] As a result, the oxygen adsorbent 50 adsorbs oxygen in the space within the bag 60 and in the inner container 20, and the content of the active ingredients in the contents 10 can be stably maintained for a long period of time.

[0052] The inner container 20 is configured to include a container body 30 that contains the contents 10, and a lid 40 that closes the container body 30.

[0053] This configuration makes it easy to store the contents 10 in the inner container 20, and when using the contents 10, the user can easily remove the contents 10 from the inner container 20.

[0054] The container body 30 consists of a bottle container body, a tube container body, a jar container body, and a dispensing container body.

[0055] This allows the content of the active ingredient in the contents 10 to be maintained stably for a long period of time, and also makes it easier for users to use the contents 10.

[0056] The bag 60 is made of a synthetic resin film on which a silica vapor-deposited film, an alumina vapor-deposited film, or an aluminum vapor-deposited film is formed, or of a laminated film on which an aluminum foil layer and a synthetic resin layer are formed.

[0057] This allows the content of the active ingredients in the contents 10 to be maintained stably for an even longer period of time. [Explanation of Symbols]
