Definitions
- the present invention relates to a storage container for storing a microneedle patch.
- liquid substances containing medicinal ingredients, ointments, cream preparations, tape preparations, patch preparations, patch preparations, and the like have been used to impart a modification effect and functional effect to the skin surface and skin stratum corneum. These are intended to permeate medicinal ingredients into the skin and apply the effect by applying or sticking to the skin surface.
- the medicinal components easily disappear and fall off due to the sweating action of the skin, contact between the skin and the outside, etc. only by applying to the skin, the above conventional preparations cannot achieve a sufficient effect.
- the skin has a barrier function that prevents foreign substances from entering the body, and it is difficult to absorb the medicinal component by simply applying or sticking the medicinal component to the skin.
- a microneedle is a microneedle whose length is less than 1 mm (Patent Document 1).
- Patent Document 1 When the microneedle is made of a substance that dissolves and disappears easily in the living body, the inserted microneedle dissolves in the skin, and is absorbed and disappears (Patent Document 2). Accordingly, if the microneedle contains a medicinal component in advance, the medicinal component can be supplied to a specific place in the skin.
- a microneedle patch is an easy-to-use product by adding an adhesive tape or the like for attaching the microneedle array to the skin.
- Microneedles are generally shorter than 1 mm in length and about 0.1 mm in diameter, so there is no pain at the time of insertion and there is no bleeding. The insertion site is quickly closed and no trace is left. As a result, microneedles are recognized as an excellent method for delivering specific medicinal ingredients to specific areas of the skin. In addition to medical uses such as vaccine delivery, microneedles are also attracting attention for their use as cosmetics such as delivery of active skin ingredients such as hyaluronic acid to the skin surface, moles and bruises.
- the initial microneedles were provided with about 100 microneedles on a rigid substrate having a size of about 1 cm 2 .
- a microneedle array has been developed that has a soft substrate and a micro needle on it.
- the problem to be solved by the present invention is to add a pressure-sensitive adhesive tape to a flexible microneedle array having a flexible substrate, and to hold a microneedle patch having a release sheet on its pressure-sensitive adhesive surface.
- the object is to provide a needle patch container.
- the microneedle patch storage container according to the present invention made to solve the above-mentioned problems is one or a plurality of bottom surfaces recessed from the peripheral portion, a side surface connecting the bottom surface and the peripheral portion, and protruding from the bottom surface.
- a release sheet portion of a flexible microneedle patch having a bottom surface convex portion is held by the bottom surface convex portion.
- One microneedle patch storage container can store as many microneedle patches as the bottom surface. Normally, one microneedle patch is stored in one microneedle patch storage container. However, for example, in the case of a microneedle patch to be attached under the eyes, it is usually attached under the left and right eyes. Also, two or more microneedle arrays can be held in one microneedle patch. In this case, two or more microneedle arrays can be stored in one container.
- the microneedle patch storage container has a recess for pressing the microneedle patch held on the bottom surface convex portion at a position corresponding to a part of the bottom surface convex portion, It is preferable that a position corresponding to a part is provided with a lid having no depression.
- the release sheet portion of the microneedle patch is held on the bottom surface convex portion.
- the concave portion of the lid is configured so as to press the entire surface, the microneedle patch is brought into close contact with the lid by the action of static electricity.
- the microneedle patch is adsorbed to the lid due to static electricity, the microneedle patch will pop out unexpectedly when the lid is removed, and it will be difficult to take out by adsorbing to the storage container. If the pressing by the recessed portion of the lid is partial, it is preferable because the influence of static electricity is weakened and the handling becomes easy. In order to reduce the influence of static electricity and prevent the microneedle patch from adsorbing to the lid, it is effective and desirable to make the area of the bottom convex portion larger than the area of the concave portion of the lid.
- the bottom surface convex portion has a substantially rectangular shape because the release sheet of the microneedle can be easily pressed and held. Moreover, this rectangular shape may be divided into several, and a plurality of convex portions may hold the four sides of the release sheet.
- the microneedle patch storage container can be stacked by fitting a plurality of the containers together.
- the microneedle patch housed in another microneedle patch container is partially pressed by the outside of the bottom surface of the microneedle patch.
- the microneedle array is provided with notches and ears at corresponding positions of the storage container and the lid portion so that the lid can be easily removed from the storage container in use. This is because the microneedle patch storage container needs to be sealed from the time of manufacture until just before use, but it must be easily taken out during use.
- microneedle patch storage container it is preferable to provide a bulging portion on the bottom surface of the microneedle patch storage container so that the microneedle patch can be pinched and easily taken out. This is because the microneedle patch can be easily picked out even when it is in close contact with the storage container due to static electricity.
- the microneedle patch storage container according to the present invention preferably has an antistatic treatment on the surface thereof. This is because when the storage container is charged, the microneedle patch is adsorbed to the storage container and becomes difficult to handle.
- the microneedle patch storage container can hold the microneedle in a sealed state, but does not necessarily hold it in a sterile state.
- a plastic sheet or an aluminum sheet can be suitably used as the sterilized film sheet. Aluminum sheets are particularly preferred because of their high sealing properties.
- a release sheet is usually placed on the active ingredient, and the release sheet is peeled off before being applied to the skin. It is usual to apply the ingredients so that they are in direct contact with the skin. In this case, cleanliness is desirable because it is put on the stratum corneum of the skin, but it is not required to be sterile because of the barrier effect of the stratum corneum.
- the conditions required for the microneedle patch storage container are stricter than the requirements for the patch storage container.
- Microneedles must be stored hygienically because they are inserted into the skin.
- the needle cannot be inserted into the skin unless it is sharp, it is impossible to apply a hard object that can break the tip of the needle.
- the needle since the needle is inserted into the skin, it should not be attached to the body, such as an adhesive, that cannot be safely determined. That is, the microneedle must be held and stored only in the part of the release sheet in a sterilized state and not in contact with any part of the container. For this reason, the microneedle patch storage container is inevitably different in structure from the patch storage container, and cannot be designed by analogy with the patch storage container.
- the method of storing the hard microneedle array cannot be used as it is. This is because the holding method differs between the hard and flexible ones.
- the material of the microneedle patch storage container is not particularly limited, but a resin that can be easily injection molded or pressed is preferable. In particular, transparent or translucent is preferable because the contents can be visually observed from the outside. It is desirable that the permeability of air and water vapor is small and the microneedle patch can be stably protected over a long period of time. Specifically, polyethylene terephthalate (PET), polypropylene (PP), and polyethylene (PE) are preferable. Among them, PET is particularly preferable because it has little deterioration and odor generation due to sterilization by ⁇ -ray and electron beam irradiation.
- PET polyethylene terephthalate
- PP polypropylene
- PE polyethylene
- the microneedle patch is held by the part of the release sheet, and the microneedle part does not contact any part of the container. Even if the microneedle patch is a flexible sheet, it can be kept hygienic until it is opened. If this storage container is used, a microneedle patch can be easily taken out when necessary. Furthermore, the storage containers can be stacked on each other, and several microneedle patches necessary for a series of use can be simply packaged.
- the microneedle patch storage container of the present invention is designed to avoid the influence of static electricity. If there is an influence of static electricity, when removing the lid, the microneedle patch will stick to the lid and jump out suddenly, or it will stick to the storage container and become difficult to take out.

- the main component is hyaluronic acid, but it contains ingredients that are effective for wrinkle removal and rejuvenation activation of the skin.
- a pressure-sensitive adhesive sheet 12 having a shape almost the same as that of the microneedle array portion and having a wide periphery of 2 to 10 mm is adhered to the surface opposite to the microneedle array surface.
- the adhesive surface is in the same direction as the array surface.
- a substantially rectangular release sheet 13 (70 ⁇ 45 mm) excluding the microneedle array portion is attached to the microneedle array surface side so as to cover the adhesive surface.
- the reason why the bottom portion of the pressure-sensitive adhesive sheet 12 is narrow is to attach the microneedle array 11 as close to the eyes as possible.
- the cutting line is provided at the center of the release sheet 13, so that the release sheet has both ends and can be brought into contact with the application site (under the eyes) while opening the release sheet.
- the adhesive sheet 12 adheres.
- the microneedle is inserted into the skin stratum corneum by lightly tapping the surface of the microneedle array 11.

Abstract
Description
また1個のマイクロニードルパッチに2個以上のマイクロニードルアレイを保持させることもできる。この場合1つの容器に2個以上のマイクロニードルアレイを収納できる。
顔面にマイクロニードルパッチを貼付してヒアルロン酸及び薬効成分を補給し、しわを除去する等の美容効果を上げるためには、通常数日にわたって貼り替えしつつ貼付する必要がある。そのため、一連の使用に必要な枚数を、ひとまとめにして包装できるのが取引上望ましいからである。
本収納容器を用いれば、マイクロニードルパッチは必要なときに容易に取り出すことができる。さらに、収納容器は互いにスタックでき、一連の使用に必要な数個のマイクロニードルパッチを簡便に包装することができる。
マイクロニードルのサイズは限定ではないが、長さ30~1000μmのニードルが50~500本/cm2程度備えられている。主成分はヒアルロン酸であるが、皮膚のしわ取りや若返り活性化に有効な成分を含んでいる。
粘着シート12の底の部分が幅狭くしてあるのは、マイクロニードルアレイ11をなるべく目に近づけて貼付するためである。
上記のマイクロニードルパッチに適した、マイクロニードルパッチ収納容器の一例を図2に示す。材質はポリエチレンテレフタレート(Polyethylene terephthalate:PET)である。
マイクロニードルパッチ収納容器30は、蓋をかぶせて閉じた収納容器とすることができる。蓋20の一例を図3に示す。マイクロニードルパッチ収納容器30や蓋20の表面は帯電防止処理が施されている。
収納容器の窪みの図上右上と左下のふくらんだ部分は、収納容器からマイクロニードルパッチを取り出すとき、マイクロニードルパッチをつまんで取り出しやすくするため設けられている。マイクロニードルパッチは収納容器にぴったり入り込んではいるが、このふくらみ部分に指を差し込むことにより、容易につまみ出すことができる。
蓋30の外側に耳26があり、収納容器30外側の対応する位置に切り込み36がある。これらは収納容器から蓋を外しやすいよう設けられたものである。
また、蓋の窪み部22は、図の上下には設けられているが左右には設けられていない。つまりマイクロニードルパッチは、図2の底面凸部34の左右部分では上から押さえつけられてはいない。上からマイクロニードルパッチを押さえつけない部分を設け、静電気の影響を避け、マイクロニードルパッチを取り出しやすくした。
また、マイクロニードルパッチを収容したマイクロニードルパッチ収納容器を、蓋をすることなく、無菌処理後減菌アルミニウムフィルムシート製袋に収納し、密閉して保持することもできる。
また、マイクロニードルパッチを収容したマイクロニードルパッチ収納容器を、蓋をすることなくヒートシール可能なフィルム又はポリエチレンとラミした滅菌紙をかぶせ、収納容器周辺部とフィルムとをヒートシールにより融着することにより密封することもできる。
マイクロニードルパッチ収納容器の他の例を図4に示す。マイクロニードルパッチ収納容器50は、蓋をかぶせて閉じた収納容器とすることができる。蓋40の一例を図5に示す。マイクロニードルパッチ収納容器50や蓋40の材質はポリエチレンテレフタレート(PET)であり、それらの表面は帯電防止処理が施されている。
図4に二重の2点鎖線で示されている領域58は、この収納容器30にマイクロニードルパッチ10を収納したときのマイクロニードル部分11が存在する部位を示しており、収納容器50の構造を示すものではない。この時、マイクロニードルパッチ10は底面凸部54と側面凸部55に支えられ、マイクロニードル部分11は収納容器50のいかなる部分にも接触していない。
蓋40の外側に耳46があり、収納容器50外側の対応する位置に切り込み56がある。これらは収納容器から蓋を外しやすいよう設けられたものである。
また、蓋の窪み部は、図の上下には設けられているが左右には設けられていない。マイクロニードルパッチは、図4の左右にある底面凸部に乗っかってはいるが、この部分では上から挟まれていない。
2個のマイクロニードルパッチを収納できるマイクロニードルパッチ収納容器の例を図6に示す。マイクロニードルパッチ収納容器60は、蓋をかぶせて閉じた収納容器とすることができる。マイクロニードルパッチ収納容器60の材質はポリエチレンテレフタレート(PET)であり、その表面は帯電防止処理が施されている。
2個のマイクロニードルアレイを保持するマイクロニードルパッチを収納できるマイクロニードルパッチ収納容器の例を図7及び図8に示す。このマイクロニードルパッチは1枚の離形シート紙に2個のマイクロニードルアレイ68を保持している。また本実施例の場合、粘着テープ69はマイクロニードルアレイの一部分にのみ付されている。
このようにすれば、図6の場合より簡便に2個のマイクロニードルアレイを収納できる。
4個のマイクロニードルアレイを1つのマイクロニードルパッチ収納容器に収納する例を示す。
マイクロニードルアレイの周辺部にのみ粘着シートを設けたマイクロニードルアレイを図9に示す。粘着シートは当然マイクのニードルアレイのマイクロニードルを設けていない側の面に備えられており、マイクロニードルが存在する部分の裏面には粘着シートは存在しないのが好都合である。
このようなマイクロニードルアレイ4個を1枚の離型シート上に保持したマイクロニードルパッチは、一度に4個のマイクロニードルパッチを使用するような場合には好都合である。
