Abstract

A water absorbing pad for a contact lens, wherein a generally sheet-like water absorbing material layer (18) is formed of a water absorbing material capable of absorbing and holding a treatment liquid (26) sealed in a contact lens case (12) for storing the contact lens (38) and the rear surface of the water absorbing material layer (18) is covered by an impermeable water leakage prevention layer (20). Since the absorbing pad is used, the treatment liquid can be prevented from being spattered when any treatment is applied to the contact lens (38) by using the treatment liquid (26) in the contact lens case (12) and the remaining treatment liquid can be easily treated. Then the use of the contact lens can be more facilitated.

[0002] 良く知られているように、コンタクトレンズは、屈折異常の矯正などの目的で人が眼 の角膜表面に重ね合わせて装用する光学品として、広く利用されている。特に近年 では、デイスポーザブルタイプと呼ばれる一日や一週間，一力月等の短期且つ有限 の装用期限が定められた使い捨て型のコンタクトレンズが開発されて安価に提供され たことに伴い、メンテナンスも容易で、手軽である等の理由から、コンタクトレンズの禾 IJ 用が大幅に増加している。  [0002] As is well known, a contact lens is widely used as an optical article worn by a person superimposed on a corneal surface of an eye for the purpose of correcting a refractive error or the like. In particular, in recent years, disposable contact lenses, which are called disposable types and have a short and finite expiration date such as one day, one week, one month, etc., have been developed and provided at low cost. Because of the ease and ease of use, the use of IJ for contact lenses has increased significantly.
[0003] ところで、コンタクトレンズを装着する場合には、従来から眼科医等で指導されてい るところによると、洗面所で手指を洗浄した後、保存液に浸漬してケースに収容したコ ンタクトレンズを指でつまんで、ケースから取り出し、それを指先に載せた状態で、必 要に応じて鏡等で装着位置を視認しつつ、見開いた眼の角膜表面に導いて重ね合 わせることによって行われる。  [0003] By the way, when a contact lens is worn, according to a conventional instruction from an ophthalmologist or the like, a contact lens which is washed in a washroom and then immersed in a preservative solution and stored in a case. Is grasped with a finger, taken out of the case, and placed on the fingertip, while visually checking the mounting position with a mirror or the like as necessary, guiding it to the corneal surface of the open eye, and superimposing it. Is
[0004] し力、しながら、コンタクトレンズを装着するために洗面所に行くのが煩わしいという問 題があり、特に外出先などでは、洗面所を探すこと自体が面倒であったり難しい場合 力 Sある。  [0004] However, there is a problem in that it is troublesome to go to the washroom to wear contact lenses. Especially when going out, it is troublesome or difficult to find the washroom itself. is there.
[0005] また、コンタクトレンズの取り扱いに慣れた人にとっては、鏡等も必ずしも必要でない ことから、喫茶店やレストランの席や車中等で、装着したり、交換したりすること等が行 われるようになってきている。ところが、そのような装着、交換場所においては、コンタ クトレンズを収容するケース内の保存液がこぼれたり、或いはコンタクトレンズを触る 手指を洗浄等することが困難であるという問題があった。特に、デイスポーザブルタイ [0005] In addition, since people who are used to handling contact lenses do not necessarily need a mirror or the like, they are required to wear or exchange them at a coffee shop, restaurant, or in a car. It has become to. However, in such a place of attachment or replacement, there has been a problem that the preservation solution in the case accommodating the contact lens spills out, or it is difficult to wash a finger touching the contact lens. In particular, disposable ties
：、一般に、一度開封すると再密封ができないケースに収容さ れていることから、コンタクトレンズを使用した後に廃棄するケースを鞫等に入れて持 ち帰る際に、ケースに充填された保存液の始末に困ることがあった。 : Generally, once opened, it cannot be resealed. Therefore, when putting the case to be discarded after using the contact lens in a tongue or the like and bringing it home, it may be difficult to dispose of the preservative solution filled in the case.
[0006] また、たとえ洗面所でコンタクトレンズを装着する場合であっても、ケースを傾けて保 存液を廃棄しょうとする際に誤って、未だ取り出していないコンタクトレンズまでケース 力 流れ出てしまうと、洗面所でコンタクトレンズを探すのが難しかったり、雑菌等がコ ンタクトレンズに付着してしまったり、コンタクトレンズに傷がついてしまったりする等の 問題が発生し易かった。  [0006] Even when a contact lens is worn in a washroom, when the case is tilted and the stored liquid is to be discarded, the case may accidentally flow out to the contact lens that has not been removed yet. In addition, it was difficult to find a contact lens in the washroom, and it was easy for problems such as bacteria to adhere to the contact lens and the contact lens to be damaged.
[0007] カロえて、コンタクトレンズを持って出かけたり、出張や旅行に行った際には、コンタク トレンズの装着だけでなぐ洗浄や保存，殺菌等といった何等かのレンズ処理を、容 易に且つ簡便に行いたいとのユーザーの要求がある。その場合には、必ずしも洗面 所などが存在するとは限らないことから、使用する洗浄液や保存液，殺菌液などの処 理に困る場合が多いのである。  [0007] When you have a calorie, when you go out with a contact lens, go on a business trip or travel, you can easily and simply perform some lens processing such as washing, preservation, sterilization, etc. just by attaching a contact lens. There is a request from the user to do so. In such a case, there is not always a washroom, so it is often difficult to treat the used washing solution, preservative solution, and sterilizing solution.

[0049] (使い捨て型コンタクトレンズケースに関する本発明の態様 1)  (Embodiment 1 of the present invention relating to disposable contact lens case)
使い捨て型コンタクトレンズケースに関する本発明の態様 1の特徴とするところは、 使い捨てタイプのコンタクトレンズを保存液に浸漬せしめた状態でユーザに提供する ための使い捨て型コンタクトレンズケースにおいて、前述のコンタクトレンズ用吸水パ ッドに関する本発明の前記態様 1乃至 10の何れかに係るコンタクトレンズ用吸水パッ ドを組み込んだ使い捨て型コンタクトレンズケースにある。 Aspects of the first aspect of the present invention relating to a disposable contact lens case, A disposable contact lens case for providing a user with a disposable contact lens immersed in a storage solution according to any one of the above-described aspects 1 to 10 of the present invention relating to the above-mentioned contact lens water-absorbing pad. It is in a disposable contact lens case incorporating a water absorption pad for contact lenses.
[0050] このような本態様に従う構造とされた使い捨て型コンタクトレンズケースにおいては、 デイスポーザブルタイプ (有限の比較的に短期な使用期限が定められた使い捨て型 )のコンタ外レンズを新規に開封して装用する際に、同時に清浄な吸水パッドが提供 されることから、力、かる吸水パッドを利用することによって使い捨て型コンタクトレンズ を、任意の場所で気軽に装用することが可能となる。特に、コンタクトレンズケースに 吸水パッドを組み込んだことにより、吸水パッドを忘れることもなぐ持ち運びにも便利 であり、し力、も必要な吸水パッドをユーザに対して効率的に提供することが可能となる  [0050] In the disposable contact lens case having the structure according to this embodiment, a disposable type (disposable type having a finite and relatively short expiration date) lens outside the contour is newly opened. At the same time, a clean water-absorbing pad is provided when worn, so that the use of a force- and water-absorbing pad makes it possible to easily wear a disposable contact lens anywhere. In particular, by incorporating a water-absorbing pad into the contact lens case, it is easy to carry without forgetting the water-absorbing pad, and it is possible to efficiently provide users with the necessary water-absorbing pad. Become
[0051] また、このようなデイスポーザブルタイプのコンタクトレンズの提供用の容器は、一般 に再封止不能とされている力 コンタクトレンズを取り出した後に残った保存液を吸水 パッドに吸収保持させることが出来る。従って、如何なる場所でコンタクトレンズを装 用する場合でも、従来から問題となり易かった、残った保存液の処理に困るようなこと がない。 [0051] Further, such a container for providing a disposable type contact lens has a water absorbing pad that absorbs and retains a preservative solution remaining after removing a force contact lens which is generally not resealable. I can do it. Therefore, no matter where the contact lens is worn, there is no problem in treating the remaining preservative solution, which has conventionally been a problem.
[0052] なお、使レ、捨て型コンタクトレンズケースの形状や大きさ、構造等は、何等限定され るものでなぐ各種のコンタクトレンズケースが採用可能である。また、後述する本発 明の態様の如くコンタクトレンズケースのベース部材を漏水防止層として利用する他 、例えばコンタクトレンズケースの蓋材を漏水防止層として利用するようにしても良い 。なお、使い捨て型コンタクトレンズケースに対する吸水パッドの組付構造は、限定さ れるものでないが、例えば吸水パッドを不透水性の袋に密封してコンタクトレンズケー スに内蔵させたり、コンタクトレンズケースの外面に貼着したりすることも可能である。 或いは、コンタクトレンズケースにおいて、処理液の収容スペースと別に、吸水パッド の収容スペースを形成することにより、共通部品を用いて処理液収容スペースと吸水 パッド収容スペースを形成しても良レ、。  [0052] The shape, size, structure, and the like of the used and disposable contact lens case are not limited at all, and various contact lens cases can be employed. Further, in addition to using the base member of the contact lens case as a water leakage prevention layer as in an embodiment of the present invention described later, for example, a cover material of the contact lens case may be used as a water leakage prevention layer. The structure of assembling the water-absorbing pad to the disposable contact lens case is not limited.For example, the water-absorbing pad is sealed in a water-impermeable bag and built into the contact lens case, or the outer surface of the contact lens case is It is also possible to stick it on. Alternatively, in the contact lens case, a space for accommodating the water absorbing pad may be formed separately from the space for accommodating the processing liquid, so that the common liquid is used to form the space for accommodating the processing liquid and the space for accommodating the water absorbing pad.
[0053] (使い捨て型コンタクトレンズケースに関する本発明の態様 2) 使い捨て型コンタクトレンズケースに関する本発明の態様 2の特徴とするところは、 上記態様 1に係る使い捨て型コンタクトレンズケースにおいて、前記コンタクトレンズ を前記保存液と共に収容するためのレンズ収容凹所が形成された硬質のベース部 材に対して不透水性のケース蓋シートを重ね合わせて固着することにより該レンズ収 容凹所を密閉した構造とされており、該レンズ収容凹所と異なる位置において、本発 明の前記態様 1乃至 10の何れかに係るコンタクトレンズ用吸水パッドを、該ケース蓋 シートと該ベース部材で挟み込んで密閉状態で組み込んだことにある。 (Embodiment 2 of the present invention relating to disposable contact lens case) A feature of the second aspect of the present invention relating to the disposable contact lens case is that, in the disposable contact lens case according to the first aspect, a lens housing recess for housing the contact lens together with the storage solution is formed.

The water absorbing pad for a contact lens according to any one of Aspects 1 to 10 above is sandwiched between the case cover sheet and the base member and incorporated in a sealed state.
[0054] このような本態様においては、コンタクトレンズケースの構成部材を巧く利用して吸 水パッドを一体的且つ密閉状態でパッキングすることが可能となる。また、本態様で は、例えば、ベース部材において、レンズ収容凹所と独立して吸水パッドの収容凹所 を形成すると共に、それらレンズ収容凹所と吸水パッド収容凹所を相互に接続するよ うに凹溝を形成することも可能であり、それによつて、例えばコンタクトレンズケースを 新規に開封して装着する際、開封後にケースを少し傾けて、レンズ収容凹所に収容 された保存液を凹溝を通じて吸水パッド収容凹所に導いて吸水パッドで吸収させた 後、保存液が少量とされ或いは略除かれたレンズ収容凹所から、手指でコンタクトレ ンズを摘んで取り出すようにすることも出来る。このような取扱レ、を可能としたコンタクト レンズケースでは、開封後にレンズ収容凹所に手指を漬け入れてコンタクトレンズを 取り出す際に、レンズ収容凹所力 保存液が零れることを効果的に防止することも可 能となる。 [0054] In such an embodiment, it is possible to pack the water-absorbing pad integrally and in a sealed state by making good use of the constituent members of the contact lens case. In this aspect, for example, in the base member, the water-absorbing pad housing recess is formed independently of the lens housing recess, and the lens housing recess and the water-absorbing pad housing recess are connected to each other. It is also possible to form a groove so that, for example, when a contact lens case is newly opened and mounted, the case is tilted slightly after opening, and the preservation liquid stored in the lens housing recess is formed into a groove. After passing through the water absorbing pad receiving recess and absorbing it with the water absorbing pad, the contact lens can be picked out from the lens receiving recess where the amount of the preservative solution has been reduced or substantially removed. In a contact lens case that allows such handling, when the fingers are immersed in the lens housing recess after opening and the contact lens is removed, the force of the lens housing recess is effectively prevented from spilling. It is also possible.
[0055] なお、ベース部材としては、従来から公知のものが何れも採用可能であり、例えば、 フッ素樹脂やポリアミド、ポリアリレート、ポリエチレン、ポリエチレンテレフタレート、ポ リ塩化ビュル、非結晶ポリオレフイン、ポリカーボネート、ポリサルフォン、ポリブチレン テレフタレート、ポリプロピレン、ポリメチルペンテン等や、或いはそれらの複合体や多 層構造体が適宜に採用される。また、ケース蓋シートも、従来力 公知のものが採用 可能であって、例えば、前記ベース部材の材料として挙げられた各種の合成樹脂材 や、アルミニウム等の金属、或いはそれら合成樹脂と金属の複合材カ S、単層或いは 積層構造の膜状として利用可能である。  As the base member, any of those conventionally known can be used. For example, a fluororesin, polyamide, polyarylate, polyethylene, polyethylene terephthalate, polychlorinated vinyl, amorphous polyolefin, polycarbonate, polysulfone For example, polybutylene terephthalate, polypropylene, polymethylpentene, or the like, or a composite or a multilayer structure thereof is appropriately employed. As the case lid sheet, a conventionally known one can be used. For example, various synthetic resin materials listed as materials for the base member, metals such as aluminum, or composites of these synthetic resins and metals can be used. It can be used as a material S, a single layer or a laminated structure.

発明を実施するための最良の形態  BEST MODE FOR CARRYING OUT THE INVENTION
[0068] 以下、本発明を更に具体的に明らかにするために、本発明の実施形態について、 図面を参照しつつ、詳細に説明する。先ず、図 1には、本発明の第一の実施形態とし てのコンタクトレンズ用吸水パッド 10を、コンタクトレンズケース 12と共に収容したレン ズ携帯用容器 14が、示されている。 Hereinafter, in order to clarify the present invention more specifically, embodiments of the present invention will be described in detail with reference to the drawings. First, FIG. 1 shows a lens portable container 14 accommodating a contact lens water absorbing pad 10 together with a contact lens case 12 as a first embodiment of the present invention.
[0069] より詳細には、吸水パッド 10は、図 2にも示されているように、展開した形態で、矩 形の略平板形状とされており、例えば 4つ折り等に折り畳むことでレンズ携帯用容器 1More specifically, as shown in FIG. 2, the water-absorbing pad 10 is in an unfolded form and is formed in a substantially rectangular flat plate shape. Container 1
4内に収容されている。なお、吸水パッド 10の形状や大きさ、レンズ携帯用容器 14に 収容される際の形態、個数等は、本実施形態に限定されるものでなぐ要求される吸 水性能やレンズ携帯用容器 14の形状や大きさ等に応じて適宜に設定され得る。 Housed in four. The shape and size of the water-absorbing pad 10 and the form and number of the water-absorbing pad 10 when housed in the lens-portable container 14 are not limited to those of the present embodiment, and the required water-absorbing performance and the lens-portable container Can be set appropriately according to the shape, size, etc.
[0070] また、力かる吸水パッド 10は、図 3に拡大してモデル的に示されているように、表皮 層 16と吸水材層 18と漏水防止層 20の三層からなる積層構造とされている。表皮層 1 6としては、短繊維の分離による塵等の発生を防止するために、例えば合成樹脂繊 維を織った布材や、合成樹脂の薄膜やフィルムに対して多数の貫通孔を形成した膜 材等が好適に採用される。そして、かかる表皮層 16には、その表面 24において、多 数の凹凸が付されている。即ち、布材で形成された表皮層 16には、織り込んだ多数 本の繊維の織目による凹凸が、表面 24に付されている。なお、表皮層 16が膜材で 形成される場合には、膜材に形成される多数の貫通孔ゃ適当に形成される凹部や 凸部等によって、表皮層 16の表面 24に凹凸が付され得る。 [0070] Further, as shown in an enlarged model in Fig. 3, the water-absorbing pad 10 that is strong has a laminated structure including three layers of a skin layer 16, a water-absorbing material layer 18, and a water-leakage prevention layer 20. ing. The skin layer 16 is made of, for example, synthetic resin fiber in order to prevent generation of dust and the like due to separation of short fibers. A cloth material woven from fibers, a film material in which a large number of through holes are formed in a thin film or film of a synthetic resin, and the like are suitably employed. The skin layer 16 has a large number of irregularities on its surface 24. That is, the surface layer 16 made of a cloth material has irregularities due to the weave of a large number of woven fibers. When the skin layer 16 is formed of a film material, the surface 24 of the skin layer 16 is made uneven by a large number of through holes formed in the film material and appropriately formed concave and convex portions. obtain.
[0071] これにより、表皮層 16の表面 24が、凹凸状の手拭き面とされている。また、表皮層 16は、相互に織られた多数の繊維の隙間によって、或いは表皮層 16が膜材で形成 される場合には多数の貫通孔が形成されることによって、透水性とされている。そして 、後述する図示しない薬液やコンタクトレンズケース 12に封入された保存液 26 (図 4 参照。）等が、表皮層 16を透過するようになっている。  [0071] Thus, the surface 24 of the skin layer 16 is an uneven hand-wiping surface. Further, the skin layer 16 is made water-permeable by gaps between a large number of mutually woven fibers, or by forming a large number of through holes when the skin layer 16 is formed of a membrane material. . Then, a chemical solution (not shown), which will be described later, and a preservation solution 26 (see FIG. 4) sealed in the contact lens case 12 are transmitted through the skin layer 16.
[0072] 吸水材層 18は、公知の各種の吸水紙や、不織布等を含む綿材、或いは布材等で 形成され得るが、特に、ポリアクリル酸塩架橋体やデンプン +アクリル酸塩グラフト架 橋体、ポリビニルアルコール変性架橋体、マレイン酸共重合物等からなる公知の吸 水性ポリマーによって形成されたものが好適に採用される。そして、この吸水材層 18 には、コンタクトレンズケース 12に封入された保存液 26の全容量を超える程度の吸 水容量が設定されている。具体的には、通常の使い捨てコンタクトレンズを提供する パッケージに収容されている保存液 26を考慮すると、一般に、 0. 1 -5. Oml、好まし くは 1. 0— 2. Omlの吸水容量とされたものが好適に採用される。  [0072] The water-absorbing material layer 18 can be formed of various known water-absorbing papers, cotton materials including nonwoven fabrics, or cloth materials. In particular, a crosslinked polyacrylate or a starch + acrylate graft frame is preferable. A polymer formed of a known water-absorbing polymer such as a bridge, a polyvinyl alcohol-modified crosslinked product, and a maleic acid copolymer is preferably employed. The water-absorbing material layer 18 has a water-absorbing capacity that exceeds the total capacity of the storage solution 26 sealed in the contact lens case 12. Specifically, given the preservative 26 contained in the package that provides normal disposable contact lenses, the water absorption capacity is generally 0.1-5. Oml, preferably 1.0--2. Oml. Is suitably adopted.
[0073] なお、本実施形態では、後述する左右二つのコンタクトレンズケース 12, 12に封入 された処理液としての保存液 26, 26力 S、一つの吸水パッド 10の吸水材層 18によつ て吸収保持されるようになっている。尤も、吸水パッド 10をコンタクトレンズケース 12 の数だけ用意して、一つの吸水パッド 10で一つのコンタクトレンズケース 12に封入さ れる保存液 26だけを吸収保持させるように、一つの吸水パッド 10の吸水材層 18の 吸水容量を設定しても良い。  In the present embodiment, the storage solution 26, 26 force S as a processing solution sealed in the two left and right contact lens cases 12, 12 described later, and the water absorbing material layer 18 of one water absorbing pad 10 are used. It is designed to be absorbed and held. However, the number of the water absorbing pads 10 is equal to the number of the contact lens cases 12, and one of the water absorbing pads 10 is provided so that only one of the preserving liquids 26 sealed in one of the contact lens cases 12 is absorbed and held by one of the water absorbing pads 10. The water absorption capacity of the water absorbing material layer 18 may be set.
[0074] 漏水防止層 20は、ポリエチレンやポリエステル等の合成樹脂フィルムや、アルミ二 ゥム箔等の金属薄膜など、不透水性の材料で形成されており、保存液 26等の透過 が防止されるようになっている。なお、漏水防止層 20は、保存液 26等を吸収するもの であっても、それを透過させて裏面に漏らさないものであれば良い。また、特に本実 施形態では、上記漏水防止層 20を形成する不透水性材料として、粘着性を有する 材料や摩擦係数の高い材料が採用されている。これにより、漏水防止層 20における 吸水材層 18で覆われた表側面と反対の裏側面等を含む外側表層には、滑り止め機 能が付されている。 [0074] The water leakage prevention layer 20 is formed of a water-impermeable material such as a synthetic resin film such as polyethylene or polyester, or a metal thin film such as aluminum foil, so that the permeation of the storage solution 26 or the like is prevented. It has become so. The water leakage prevention layer 20 absorbs the preservation solution 26 and the like. However, any material may be used as long as it allows the light to pass through and does not leak to the back surface. In particular, in the present embodiment, as the water-impermeable material forming the water leakage prevention layer 20, a material having adhesiveness or a material having a high coefficient of friction is employed. Thus, the outer surface layer including the back surface opposite to the front surface covered with the water absorbing material layer 18 in the water leakage prevention layer 20 has a non-slip function.
[0075] 而して、吸水材層 18における表側面としての一方（図 3中、上）の面に表皮層 16が 重ね合わせられて、該表側面の略全面が表皮層 16で覆われていると共に、吸水材 層 18における裏側面としての他方（図 3中、下）の面に漏水防止層 20が重ね合わせ られて、該裏側面の略全面が漏水防止層 20で覆われている。これによつて、表皮層 16と吸水材層 18と漏水防止層 20が、それぞれの略全面を相互に重ね合わされて、 コンタクトレンズ用吸水パッド 10が構成されている。なお、吸水パッド 10における各層 の重ね合わせ面は、必要に応じて、全面或いは部分的に相互に固着される。  [0075] Thus, the skin layer 16 is superimposed on one (upper in FIG. 3) surface as the surface of the water-absorbing material layer 18, and substantially the entire surface of the surface is covered with the skin layer 16. At the same time, a water leakage prevention layer 20 is superimposed on the other (lower in FIG. 3) surface as the back surface of the water absorbing material layer 18, and substantially the entire back surface is covered with the water leakage prevention layer 20. Thereby, the skin layer 16, the water-absorbing material layer 18, and the water-leakage prevention layer 20 are substantially superimposed on each other to form a water-absorbing pad 10 for a contact lens. The superposed surfaces of the layers of the water-absorbing pad 10 are entirely or partially fixed to each other as necessary.
[0076] ところで、吸水パッド 10と組み合わせて採用される、処理液容器としてのコンタクトレ ンズケース 12は、従来から公知の各種の形状や構造のものが何れも採用可能であり 、レンズ携帯用容器 14としても、その形状や構造，材質等は何等限定されるものでな レ、。  Meanwhile, as the contact lens case 12 as a treatment liquid container, which is employed in combination with the water absorbing pad 10, any of conventionally known various shapes and structures can be employed. However, its shape, structure, material, etc. are not limited at all.
[0077] 例えば、本実施形態では、レンズ携帯用容器 14として、略矩形箱体形状の本体ケ ース 28に対して、それに対応した矩形状の蓋体 30が、突起と貫通穴または窪みによ り係合し、この係合部を支点として開閉可能に取り付けられたものが採用されている。 また、蓋体 30は、ヒンジ構造や連結ピン等によって本体ケース 28に対して開閉可能 に取り付けられていても良い。また、レンズ携帯用容器 14における蓋体 30の内側面 等には、鏡が装備されていることが望ましい。  For example, in the present embodiment, as the lens portable container 14, a rectangular cover 30 corresponding to the main body case 28 having a substantially rectangular box shape is provided with protrusions and through holes or depressions. It is more engaged, and is mounted so as to be openable and closable with this engaging portion as a fulcrum. Further, the lid 30 may be attached to the main body case 28 so as to be openable and closable by a hinge structure, a connecting pin or the like. Further, it is desirable that a mirror is provided on the inner side surface of the lid 30 in the lens portable container 14 or the like.
[0078] また、コンタクトレンズケース 12は、全体として略平面視ハート形状を呈する容器本 体 32とカバーシート 34を含んで構成されており、容器本体 32に設けられた略半球 状の底面を有するレンズ収納部 36にコンタクトレンズ 38と保存液 26が収容されてい ると共に、レンズ収納部 36の開口部分を覆蓋するようにしてカバーシート 34が被せら れており、レンズ収納部 36の開口部の周囲において、カバーシート 34が容器本体 3 2に剥離可能に接着されている。これにより、コンタクトレンズケース 12は、コンタクトレ ンズ 38を保存液 26に浸漬して密封保存するようになっている。また、コンタクトレンズ 38の使用時には、カバーシート 34を容器本体 32から剥離して、保存液 26からコンタ クトレンズ 38を手指で摘んで取り出すようになっており、コンタクトレンズ 38を取り出し た後は、廃棄することで、再利用等のための、レンズ収納部 36の再密封は不可能と されている。 [0078] The contact lens case 12 is configured to include a container body 32 and a cover sheet 34 that have a heart shape in a substantially planar view as a whole, and has a substantially hemispherical bottom surface provided in the container body 32. A contact lens 38 and a preservative solution 26 are stored in the lens storage section 36, and a cover sheet 34 is covered so as to cover the opening of the lens storage section 36. Around the periphery, a cover sheet 34 is peelably adhered to the container body 32. As a result, the contact lens case 12 The lens 38 is immersed in the preservation solution 26 and stored tightly. Also, when using the contact lens 38, the cover sheet 34 is peeled off from the container body 32, and the contact lens 38 is picked out from the preservative solution 26 by a finger and removed. Therefore, it is impossible to reseal the lens housing portion 36 for reuse or the like.
[0079] なお、コンタクトレンズ 38や保存液 26の種類や材質等は限定されるものでないが、 本実施形態において、コンタクトレンズ 38は、例えば HEMA (ヒドロキシェチルメタク リレート）を素材とする使い捨てタイプの親水性ソフトコンタクトレンズとされていると共 に、保存液 26は、コンタクトレンズ 38の乾燥を防ぎ、且つレンズ 38をすぐに使用でき る状態に維持せしめるものであって、例えば無菌水溶液や等浸透圧食塩水等とされ ている。また、特に限定されるものでなレ、が、保存液 26の容量は、 1. 0-2. Omlとさ れており、レンズ収納部 36に略充填されている。  The type and material of the contact lens 38 and the storage solution 26 are not limited, but in the present embodiment, the contact lens 38 is a disposable material made of, for example, HEMA (hydroxyethyl methacrylate). Along with being a type of hydrophilic soft contact lens, the preservation solution 26 prevents the contact lens 38 from drying out and keeps the lens 38 ready for use. It is called isotonic saline. Although not particularly limited, the volume of the preservation solution 26 is set to 1.0-2. Oml, and the storage solution 26 is substantially filled in the lens storage portion 36.
[0080] また、本実施形態では、上述の如きコンタクトレンズケース 12の二つ力 本体ケース  Further, in the present embodiment, the two-power body case of the contact lens case 12 as described above
28の底部に並置されて収容されるようになっている。また、二つのコンタクトレンズケ ース 12の横には、吸水パッド 10が、必要に応じて折り畳まれて、並置されて収容され るようになっている。これにより、一つ以上の吸水パッド 10が二つのコンタクトレンズケ ース 12, 12と共にレンズ携帯用容器 14に収容されて、全体として携帯可能とされて いる。  28 are arranged side by side at the bottom. In addition, beside the two contact lens cases 12, the water-absorbing pads 10 are folded as necessary and housed side by side. As a result, one or more water-absorbing pads 10 are accommodated in the lens-portable container 14 together with the two contact lens cases 12 and 12, and are made portable as a whole.
[0081] なお、図面上に明示されていないが、レンズ携帯用容器 14内には、コンタクトレン ズケース 12や吸水パッド 10の収容スペースと別に、別の処理液容器としての薬液容 器の収容スペースやコンタクトレンズを取り出すためのピンセットやスポイト等の収容 スペースを形成しても良レ、。そこにおいて、この薬液容器は、吸水パッド 10ゃコンタク トレンズケース 12と別体形成されると共に、薬液容器には、コンタクトレンズ 38を手指 等で取り扱う際に手指の消毒を行うことの出来る、処理液としての適当な消毒液乃至 は殺菌液、或いはコンタクトレンズ 38の洗浄液などの薬液が収容される。これにより、 コンタクトレンズケース 12に加えて薬液容器と吸水パッド 10を組み合わせてなるコン タクトレンズ用吸水パッドセットが、構成される。  Although not explicitly shown in the drawings, the lens portable container 14 has a space for accommodating a chemical solution container as another treatment liquid container separately from the space for accommodating the contact lens case 12 and the water absorbing pad 10. It is okay to create a space for accommodating tweezers and droppers for taking out contact lenses. In this case, this chemical solution container is formed separately from the water absorbing pad 10 and the contact lens case 12, and the chemical solution container is a processing solution capable of disinfecting the fingers when handling the contact lens 38 with fingers or the like. An appropriate disinfecting solution or disinfecting solution, or a chemical solution such as a cleaning solution for the contact lens 38 is stored. As a result, a contact lens water-absorbing pad set including the chemical liquid container and the water-absorbing pad 10 in addition to the contact lens case 12 is configured.
[0082] このようなレンズ携帯用容器 14を利用すると、レストラン等の席や車内、屋外等の適 当な任意の場所において、コンタクトレンズ 38の装着や交換を容易に行うことが出来 る。以下に、力かるレンズ携帯用容器 14を利用したコンタクトレンズ 38の装着の一態 様を、例示する。 [0082] When such a lens portable container 14 is used, it is suitable for seats in restaurants, etc., in cars, outdoors, etc. At any suitable place, the contact lens 38 can be easily mounted or replaced. The following is an example of one embodiment of mounting the contact lens 38 using the powerful lens portable container 14.
[0083] 先ず、適当な任意の場所において、レンズ携帯用容器 14を開蓋して吸水パッド 10 をレンズ携帯用容器 14から取り出し、折り畳んであった吸水パッド 10を広げると共に 、吸水パッド 10の漏水防止層 20を下面として、吸水パッド 10を任意の場所の安定し た位置に載置する。  First, at an appropriate place, the lens portable container 14 is opened, the water absorbing pad 10 is taken out of the lens portable container 14, the folded water absorbing pad 10 is spread, and the water absorbing pad 10 is leaked. The water-absorbing pad 10 is placed at a stable position at an arbitrary position with the prevention layer 20 facing downward.
[0084] 次に、コンタクトレンズケース 12をレンズ携帯用容器 14から取り出して、吸水パッド 10の上方にレンズケース 12を位置せしめて、容器本体 32からカバーシート 34を剥 離する。  Next, the contact lens case 12 is taken out of the lens portable container 14, the lens case 12 is positioned above the water absorbing pad 10, and the cover sheet 34 is separated from the container body 32.
[0085] その後、図 4にも示されているように、カバーシート 34を剥離した容器本体 32を任 意の方向に傾斜させて、容器本体 32のレンズ収納部 36に収容した保存液 26の全 量乃至は適量を吸水パッド 10に流し落とす。コンタクトレンズ 38を取り出す手指を吸 水パッド 10の手拭き面 24にて拭き取り清掃を行った後に、保存液 26から露出したコ ンタクトレンズ 38を、指で上力 押さえつけて、或いは摘みながら、レンズ収納部 36 の底面から開口周縁部に向かって滑らして該開口周縁部から摘み上げるようにして 取り出す。このときもちろんのこと、手指が清潔な状態であれば、手拭き清掃は不要 である。或いは、保存液 26を吸水パッド 10に流し落としつつ、保存液 26に浸漬した 状態のコンタクトレンズ 38を、上述のようにレンズ収容部 36から取り出しても良レ、。こ れにより、コンタクトレンズ 38をコンタクトレンズケース 12から取り出す。  Thereafter, as shown in FIG. 4, the container main body 32 from which the cover sheet 34 has been peeled off is tilted in any direction so that the preservation liquid 26 stored in the lens storage portion 36 of the container main body 32 is removed. The entire amount or an appropriate amount is poured into the water absorbing pad 10. After removing the contact lens 38 with your fingers by wiping it off with the hand wiping surface 24 of the water-absorbing pad 10, hold down the contact lens 38 exposed from the preservative solution 26 with your finger or hold it down while holding the lens. Gently slide from the bottom of 36 toward the edge of the opening and pick it up from the edge of the opening. At this time, of course, if the fingers are clean, hand wiping is unnecessary. Alternatively, the contact lens 38 immersed in the preservative solution 26 may be taken out of the lens housing portion 36 as described above while the preservative solution 26 flows down to the water absorbing pad 10. Thus, the contact lens 38 is taken out of the contact lens case 12.
[0086] そこにおいて、レンズケース 12からカバーシート 34を剥離する際に零れる保存液 2 6や、レンズケース 12を傾斜させて滴下された保存液 26、更に手指でコンタクトレン ズ 38を摘み上げる際に零れる保存液 26は、何れも、下方に敷設された吸水パッド 1 0に滴下される。そこにおいて、吸水パッド 10に滴下された保存液 26は、表皮層 16 を通じて内部に速やかにしみ込み、吸水材層 18に吸収保持される。また、吸水材層 18に吸収保持された保存液 26は、漏水防止層 20を透過することはなぐそれ故、吸 水パッド 10の載置面を保存液 26で濡らすようなことがない。  [0086] There, the preservation solution 26 that spills when the cover sheet 34 is peeled off from the lens case 12, the preservation solution 26 that is dropped by inclining the lens case 12, and furthermore, when the contact lens 38 is picked up by a finger. Any of the preservative solution 26 that spills into the water-absorbing pad 10 laid below is dropped. The preservation solution 26 dropped on the water absorbing pad 10 quickly penetrates into the inside through the skin layer 16 and is absorbed and held by the water absorbing material layer 18. Further, the preservation solution 26 absorbed and retained in the water absorbing material layer 18 does not pass through the water leakage prevention layer 20, so that the mounting surface of the water absorption pad 10 does not wet with the preservation solution 26.
[0087] さらに、レンズケース 12のレンズ収納部 36に残った保存液 26を全て吸水パッド 10 上にこぼして吸収保持させても良い。特に吸水材層 18として、吸水した保存液 26を ゲルィヒして保持し得る高分子吸水材を利用してレ、ることにより、一度吸収した保存液 26が再び滲み出したりすることがないようにすることが出来るのであり、それによつて 、例えば使用後のレンズケース 12と吸水パッド 10を、鞫等に入れて持ち帰って、適 当な場所で廃棄するようにしても、保存液 26で鞫の中が濡れてしまうようなこともない のである。 [0087] Further, all of the preservative solution 26 remaining in the lens storage section 36 of the lens case 12 is absorbed by the water absorbing pad 10 It may be spilled over and absorbed and held. In particular, by using a polymer water-absorbing material that can hold the absorbed storage solution 26 by gelling as the water-absorbing material layer 18 so that the once absorbed storage solution 26 does not seep out again. Therefore, even if, for example, the used lens case 12 and the water-absorbing pad 10 are brought back in a towel or the like and discarded in an appropriate place, the preservation solution 26 can be used to remove the water. The inside does not get wet.
[0088] なお、本実施形態では、コンタクトレンズ 38の取り扱いを容易とするために、容器本 体 32を任意の方向に傾斜させている力 容器本体 32を水平にしたままで、レンズ収 納部 36に手指を差し入れてコンタクトレンズ 38を取り出すことも勿論可能である。そ こにおいて、かかる取り出しに際しても、吸水パッド 10の上方に容器本体 32を位置 せしめて、コンタクトレンズ 38を保存液 26から取り出すようにされることが望ましぐそ れによって、レンズ収納部 36から零れ落ちるおそれのある保存液 26が、吸水パッド 1 0の吸水材層 18に吸収保持されることとなる。  In the present embodiment, in order to facilitate the handling of the contact lens 38, the force for tilting the container body 32 in an arbitrary direction, the lens housing part is kept horizontal while the container body 32 is kept horizontal. Of course, it is also possible to insert a finger into 36 and take out the contact lens 38. In such a case, it is desirable that the container body 32 be positioned above the water absorbing pad 10 so that the contact lens 38 is removed from the preservation solution 26, so that the contact lens 38 falls out of the lens housing 36. The preservation solution 26 that may fall is absorbed and held in the water absorbing material layer 18 of the water absorbing pad 10.
[0089] また、上述のコンタクトレンズ 38の取り扱いなどに際して、手指に付着した保存液 2 6等は、吸水パッド 10における表皮層 16の表面（手拭き面） 24で拭うことが可能であ る。  In handling the above-mentioned contact lens 38, the preservation solution 26 and the like adhering to the fingers can be wiped with the surface (hand-wiping surface) 24 of the skin layer 16 in the water-absorbing pad 10.
[0090] さらに、吸水パッド 10の吸水容量を、コンタクトレンズケース 12に収容された保存液 26の量よりも大きく設定しておくことにより、例えば、図示しない薬液容器に収容せし めて携帯した消毒液等を吸水パッド 10上に滴下しつつ手指を消毒することも可能で ある。また、吸水材層 18として、押圧することで吸収した薬液が表面に再び滲み出す ような材質 (例えば、綿材等）を採用すれば、かかる吸水材層 18に吸収保持せしめた 消毒剤等の薬液を利用して、手拭き面 24で手指を拭うことで消毒等することが可能と なる。  Further, by setting the water absorbing capacity of the water absorbing pad 10 to be larger than the amount of the preservative solution 26 stored in the contact lens case 12, for example, the water absorbing pad 10 is stored in a chemical solution container (not shown) and carried. It is also possible to disinfect the fingers while dripping a disinfecting solution or the like on the water absorbing pad 10. Also, if a material (for example, a cotton material, etc.) is used as the water absorbing material layer 18 so that the chemical solution absorbed by pressing will ooze out to the surface again, a disinfectant or the like absorbed and retained in the water absorbing material layer 18 can be used. It is possible to perform disinfection or the like by wiping a finger with the hand wiping surface 24 using a chemical solution.
[0091] 従って、上述の如き構造とされたコンタクトレンズ用吸水パッド 10を採用することに より、コンタクトレンズ 38をレンズケース 12から取り出して装着する際に、レンズケース 12から零れ落ちる保存液 26で装着場所を濡らしたり、汚したりすることが防止される 。それ故、コンタクトレンズ 38の装着を、適当な任意の場所で便利に行うことが可能と なるのである。 [0092] また、本実施形態では、手拭き面 24を備えた表皮層 16が、吸水材層 18と別体形 成されていることにより、特に手拭きに適した材料で表皮層 16を形成すると共に、吸 水に適した材料で吸水材層 18を形成することが可能となる。 [0091] Therefore, by employing the contact lens water-absorbing pad 10 having the above-described structure, when the contact lens 38 is taken out of the lens case 12 and attached, the preservation liquid 26 that spills from the lens case 12 can be used. Wetting or soiling of the mounting location is prevented. Therefore, the wearing of the contact lens 38 can be conveniently performed at any appropriate place. [0092] In the present embodiment, the skin layer 16 having the hand wiping surface 24 is formed separately from the water absorbing material layer 18, so that the skin layer 16 is formed of a material particularly suitable for hand wiping. The water-absorbing material layer 18 can be formed of a material suitable for absorbing water.
[0093] 更にまた、本実施形態では、コンタクトレンズ 38をレンズケース 12から取り出す際に 、万一、ケース 12からコンタクトレンズ 38を落とした場合においても、レンズ 38が吸水 パッド 10の表面上に保持されることから、コンタクトレンズ 38の紛失も効果的に防止さ れ得る。  Further, in the present embodiment, even when the contact lens 38 is dropped from the case 12 when the contact lens 38 is taken out of the lens case 12, the lens 38 is held on the surface of the water absorbing pad 10. Therefore, loss of the contact lens 38 can be effectively prevented.
[0094] また、本実施形態では、漏水防止層 20の外側表層が滑り止め機能を備えているこ とにより、吸水パッド 10を適当な場所に載置して手指の拭き取り作業等を行う際に、 吸水パッド 10の位置ずれ等が防止されることとなり、手拭き作業が安定して実現され ることから、使用感ゃ拭き取り効果等の更なる向上が図られ得る。  In the present embodiment, since the outer surface layer of the water leakage prevention layer 20 has a non-slip function, the water absorption pad 10 can be placed at an appropriate place to perform a finger wiping operation or the like. In addition, since the displacement of the water-absorbing pad 10 and the like are prevented, and the hand wiping operation is stably realized, the usability and the wiping effect can be further improved.
[0095] 以下、本発明の別の実施形態としてのコンタクトレンズ用吸水パッド等を、更に幾つ か例示するが、以下に挙げる実施形態において、第一の実施形態と同様な構造とさ れた部材および部位については、図中に、第一の実施形態と同一の符号を付するこ とにより、それらの詳細な説明を省略する。  [0095] Hereinafter, some examples of the water-absorbing pad for a contact lens and the like as another embodiment of the present invention will be further described. In the embodiments described below, members having the same structure as the first embodiment are described. The parts and portions are denoted by the same reference numerals in the drawings as in the first embodiment, and detailed description thereof will be omitted.
[0096] 図 5には、本発明の第二の実施形態としてのコンタクトレンズ用吸水パッド 40の要 部が拡大して示されている。本実施形態の吸水パッド 40における表皮層 16は、合成 樹脂材の薄膜で形成されており、その表側面には、小突起 42の多数が一体的に突 設されている。これにより、表皮層 16の表側面が、多数の小さな起伏を有する凹凸状 の手拭き面 44とされている。また、表皮層 16には、微小な貫通孔 43が多数設けられ ており、充分な透水性が付与されている。  FIG. 5 is an enlarged view of a main part of a water absorption pad 40 for a contact lens according to a second embodiment of the present invention. The skin layer 16 in the water-absorbing pad 40 of the present embodiment is formed of a thin film of a synthetic resin material, and a large number of small projections 42 are integrally formed on the surface of the surface. As a result, the surface of the skin layer 16 is formed as an uneven hand-wiping surface 44 having many small undulations. Further, the skin layer 16 is provided with a large number of minute through-holes 43 to provide sufficient water permeability.
[0097] また、表皮層 16の手拭き面 44と反対側の裏側面には、吸水材層 48が重ね合わさ れて配設されている。特に本実施形態では、かかる吸水材層 48として、一度吸収せ しめた保存液等の液体を、押圧力を加えることで再び絞り出すことの出来る材料、例 えば人工又は天然の繊維からなる織布ゃ不織布，或いは海綿状の合成樹脂材等に よって形成されたものが採用されている。  [0097] Further, a water-absorbing material layer 48 is provided on the back side surface of the skin layer 16 opposite to the hand-wiping surface 44 so as to overlap. Particularly, in the present embodiment, as the water-absorbing material layer 48, a material such as a preservative solution once absorbed can be squeezed again by applying a pressing force, for example, a woven fabric made of artificial or natural fibers. A nonwoven fabric or a spongy synthetic resin material is used.
[0098] 更にまた、吸水材層 48における表皮層 16と反対の裏側には、薬液保持層 46が重 ね合わされて配設されている。力、かる薬液保持層 46は、不透水性の合成樹脂フィル ムの密閉袋 47に対して、その内部に殺菌剤等の適当な薬液 49を収容して密封せし めた構造とされている。なお、かかる密閉袋 47は、外部から手指等で押圧することに より、比較的容易に破裂するようになっている。そして、密閉袋 47が破裂すると、内部 の薬液 49が外部に漏れ出して、吸水材層 48に染み込むようになつており、その後、 外部から手指で吸水パッド 40を押さえることによって、吸水材層 48に染み込んだ薬 液 49が、貫通孔 43を通じて、表皮層 16の表面（手拭き面） 44に滲み出すようになつ ている。 [0098] Further, on the back side of the water-absorbing material layer 48 opposite to the skin layer 16, a chemical solution holding layer 46 is disposed so as to overlap. The liquid and liquid chemical holding layer 46 is made of water-impermeable synthetic resin The structure is such that an appropriate chemical solution 49 such as a bactericide is contained in the airtight bag 47 of the system and sealed therein. The sealed bag 47 can be relatively easily ruptured by pressing with a finger or the like from the outside. When the sealed bag 47 ruptures, the chemical solution 49 inside leaks out and permeates the water-absorbing material layer 48. Thereafter, the water-absorbing material layer 48 is pressed by pressing the water-absorbing pad 40 from outside with fingers. The liquid solution 49 soaked into the surface layer (the hand-wiping surface) 44 of the skin layer 16 leaks through the through-hole 43.
[0099] さらに、薬液保持層 46の裏側には、クッション層 50が重ね合わされている。クッショ ン層 50は、例えば発泡ポリエチレンや発泡ポリウレタン、発泡ポリブタジエン等を含 む発泡合成樹脂によって形成されており、適度な弾性を有している。なお、クッション 層 50は、保存液 26を含侵保持または通過させるものであっても良いし、撥水性のも のや不透水 1生のものであっても良い。  [0099] Further, a cushion layer 50 is overlaid on the back side of the chemical solution holding layer 46. The cushion layer 50 is formed of a foamed synthetic resin containing, for example, foamed polyethylene, foamed polyurethane, foamed polybutadiene, and the like, and has an appropriate elasticity. The cushion layer 50 may be one that impregnates and retains or allows the preservation solution 26 to pass through, or may be one that is water-repellent or one that is impermeable to water.
[0100] また、クッション層 50の裏側面には、漏水防止層 20が重ね合わされている。これに より、クッション層 50が、吸水材層 48と漏水防止層 20の間に配設されている。その結 果、本実施形態の吸水パッド 40が、表皮層 16,吸水材層 48，薬液保持層 46，タツ シヨン層 50および漏水防止層 20からなる五層の積層構造とされている。  [0100] On the back side of the cushion layer 50, the water leakage prevention layer 20 is superimposed. Thus, the cushion layer 50 is provided between the water absorbing material layer 48 and the water leakage prevention layer 20. As a result, the water-absorbing pad 40 of the present embodiment has a five-layer laminated structure including the skin layer 16, the water-absorbing material layer 48, the chemical solution holding layer 46, the sacrifice layer 50, and the water leakage prevention layer 20.
[0101] 従って、上述の如き構造とされた本実施形態のコンタクトレンズ用吸水パッド 40に おいては、前記第一の実施形態の吸水パッド 40と同様な効果を発揮し得るのであり 、それに加えて、使用時に薬液保持層 46に予め含侵保持された薬液 49を必要に応 じて手拭き面 44に滲み出させて、かかる薬液 49で手指を殺菌等することが出来るの である。  Therefore, the water absorbing pad 40 for a contact lens according to the present embodiment having the above-described structure can exhibit the same effect as the water absorbing pad 40 according to the first embodiment. As a result, the chemical solution 49 previously impregnated and held in the chemical solution holding layer 46 at the time of use is allowed to seep out to the hand-wiping surface 44 as necessary, and the fingers can be sterilized with the chemical solution 49.
[0102] また、本実施形態では、吸水材層 48の下方にクッション層 50が設けられていること により、表皮層 16の手拭き面 44で手指を拭う際に、良好な使用感ゃ高級感が発揮さ れるのである。  [0102] Further, in the present embodiment, the cushion layer 50 is provided below the water-absorbing material layer 48, so that when the fingers are wiped with the hand-wiping surface 44 of the skin layer 16, a good feeling of use and a sense of quality are obtained. It is demonstrated.
[0103] 次に、図 6には、本発明の第三の実施形態としてのコンタクトレンズ用吸水パッド 52 が示されている。  Next, FIG. 6 shows a water absorption pad 52 for a contact lens as a third embodiment of the present invention.
[0104] 本実施形態の吸水パッド 52における吸水材層 54は、略矩形平板形状を呈してお り、麻や木綿等を含む天然の綿材又は布材や、或いはポリエチレンやポリエステル、 エチレン '酸化ビュル共重合体等の不織布等を含む人工の綿材又は布材からなる 吸水材によって形成されている。また、吸水材層 54の表側面は、そのまま外部に露 呈されており、使用時に手指を拭う手拭き面 56とされている。また、本実施形態では 、手拭き面 56と吸水材層 54がー体形成されているが、それぞれ、同一素材または異 なる素材によって別体形成された後に相互に重ね合わされることによって、吸水パッ ド 52の一部を構成しても良レ、。また、吸水材層 54には、コンタクトレンズケース 12に 封入された保存液 26の全量を吸収保持し得るだけでなぐ必要量の薬液をあわせて 含侵保持し得るだけの吸水容量が設定されている。そして、吸水材層 54には、殺菌 剤等の所定の薬液が予め所定量だけ含侵保持されており、吸水材層 54が押さえつ けられることによって、吸水材層 54の手拭き面 56に薬液が滲み出すようになつている 。即ち、吸水材層 54は、保存液 26を吸収保持すると共に、薬液を予め含侵保持する 薬液保持層として構成されてレ、る。 [0104] The water-absorbing material layer 54 of the water-absorbing pad 52 of the present embodiment has a substantially rectangular flat shape, and is made of natural cotton or cloth including hemp and cotton, or polyethylene, polyester, or the like. It is formed of a water-absorbing material made of artificial cotton or cloth including non-woven fabric such as ethylene-butyl oxide copolymer. Further, the front side surface of the water absorbing material layer 54 is exposed to the outside as it is, and serves as a hand wiping surface 56 for wiping a finger during use. Further, in the present embodiment, the hand wiping surface 56 and the water absorbing material layer 54 are formed separately, but they are formed separately from the same material or different materials, and then superimposed on each other to form the water absorbing pad. It's okay to configure a part of 52. The water-absorbing material layer 54 is set to have a water-absorbing capacity sufficient to absorb and retain the entire amount of the preservative solution 26 sealed in the contact lens case 12 and to impregnate and retain the necessary amount of the chemical solution. I have. A predetermined amount of a chemical such as a germicide is impregnated and held in the water absorbing material layer 54 in advance by a predetermined amount. When the water absorbing material layer 54 is pressed, the chemical cleaning solution is applied to the hand-wiping surface 56 of the water absorbing material layer 54. Is oozing out. That is, the water-absorbing material layer 54 is configured as a chemical liquid holding layer that absorbs and holds the storage liquid 26 and impregnates and holds the chemical liquid in advance.
[0105] また、吸水材層 54の手拭き面 56と反対側の裏側面には、漏水防止層 20が重ね合 わされている。本実施形態の漏水防止層 20は、吸水材層 54よりも一回り大きな略矩 形薄板形状を有しており、表側面の中央部分に吸水材層 54が載置されて、必要に 応じて、溶着もしくは粘着テープや接着剤等により固着されてレ、る。  [0105] Further, a water leakage prevention layer 20 is superimposed on the back side surface of the water absorbing material layer 54 opposite to the hand wiping surface 56. The water leakage prevention layer 20 of the present embodiment has a substantially rectangular thin plate shape that is slightly larger than the water absorption material layer 54, and the water absorption material layer 54 is placed at the center of the front surface, and if necessary, , Which are fixed by welding or with an adhesive tape or an adhesive.
[0106] さらに、吸水材層 54の手拭き面 56側には、蓋シート 58が被せられている。かかる 蓋シート 58は、漏水防止層 20と略同じ大きさの略矩形薄板形状を有しており、漏水 防止層 20と同様に適当な不透水性材料で形成されている。また、蓋シート 58の外周 縁部は、漏水防止層 20の表側面の吸水材層 54の周りに位置する外周縁部に対し て、密着状態で剥離可能に固着されている。これにより、蓋シート 58と漏水防止層 20 が協働して吸水材層 54が密閉状のパック構造とされており、吸水パッド 52の使用時 には、蓋シート 58を漏水防止層 20から剥離できるようになつている。  [0106] Further, a lid sheet 58 is covered on the hand-wiping surface 56 side of the water-absorbing material layer 54. The lid sheet 58 has a substantially rectangular thin plate shape having substantially the same size as the water leakage prevention layer 20, and is formed of an appropriate water-impermeable material similarly to the water leakage prevention layer 20. Further, the outer peripheral edge of the lid sheet 58 is adhered to the outer peripheral edge located around the water-absorbing material layer 54 on the front side surface of the water leakage prevention layer 20 in a tightly contacting and releasable manner. As a result, the lid sheet 58 and the water leakage prevention layer 20 cooperate to form the water-absorbing material layer 54 in a sealed pack structure, and when the water-absorbing pad 52 is used, the lid sheet 58 is peeled from the water leakage prevention layer 20. You can do it.
[0107] 上述の如き構造とされた本実施形態のコンタクトレンズ用吸水パッド 52においては 、吸水材層 54が蓋シート 58と漏水防止層 20によって密閉されていることから、吸水 材層 54が外部雑菌から保護されると共に、吸水材層 54に含侵保持される薬液の蒸 散が抑えられる。  In the water-absorbing pad 52 for a contact lens according to the present embodiment having the above-described structure, the water-absorbing material layer 54 is sealed by the lid sheet 58 and the water-leakage prevention layer 20, so that the water-absorbing material layer 54 is While being protected from various bacteria, evaporation of the chemical solution impregnated and held in the water absorbing material layer 54 is suppressed.
[0108] また、本実施形態では、吸水材層 54が薬液を含侵保持せしめる薬液保持層とし構 成されていると共に、吸水材層 54の表側面が手拭き面 56とされていることから、全体 として簡単な構造で実現され得る。 In the present embodiment, the water-absorbing material layer 54 is formed as a chemical-solution holding layer that impregnates and holds the chemical solution. In addition, since the front surface of the water absorbing material layer 54 is a hand-wiping surface 56, the structure can be realized with a simple structure as a whole.
[0109] 次に、図 7— 8には、本発明の第四の実施形態としての使い捨て型コンタクトレンズ ケース 60が示されている。力、かるコンタクトレンズケース 60は、ベース部材 62とケー ス蓋シート 64を含んで構成されており、ベース部材 62にコンタクトレンズ 38および保 存液 26を収容して、ケース蓋シート 64をベース部材 62に剥離可能に固着することに より、コンタクトレンズ 38を密封収容すると共に、必要に応じて取り出すことが出来るよ うになつている。 [0109] Next, Figs. 7-8 show a disposable contact lens case 60 as a fourth embodiment of the present invention. The contact lens case 60 includes a base member 62 and a case cover sheet 64.The contact member 38 and the storage liquid 26 are stored in the base member 62, and the case cover sheet 64 is attached to the base member 62. By being releasably fixed to 62, the contact lens 38 can be sealed and housed, and can be taken out as needed.
[0110] 詳細には、ベース部材 62は、略長手の矩形平板形状を有していると共に、ポリプロ ピレンやポリエチレン等の硬質の合成樹脂により射出成形等によって形成されている 。また、ベース部材 62の長手方向一方の側には、レンズ収容凹所 66が設けられてい る。レンズ収容凹所 66の開口部は、略円形とされて、ベース部材 62の上面に開口し ていると共に、レンズ収容凹所 66の底部は、ベース部材 62の下方に向かって略半 球状に突出している。更に、レンズ収容凹所 66には、コンタクトレンズ 38と保存液 26 が収容されている。  [0110] Specifically, the base member 62 has a substantially elongated rectangular flat plate shape, and is formed by injection molding or the like using a hard synthetic resin such as polypropylene or polyethylene. On one side in the longitudinal direction of the base member 62, a lens housing recess 66 is provided. The opening of the lens housing recess 66 is formed in a substantially circular shape and is opened on the upper surface of the base member 62, and the bottom of the lens housing recess 66 projects substantially hemispherically below the base member 62. ing. Further, the contact lens 38 and the storage solution 26 are stored in the lens receiving recess 66.
[0111] また、ベース部材 62の長手方向でレンズ収容凹所 66と反対側には、吸水用凹所 6 8が設けられている。吸水用凹所 68は、レンズ収容凹所 66と同じようにベース部材 6 2の上面に開口して、所定の深さ寸法で略矩形状に凹設されている。これにより、吸 水用凹所 68の底部 70がベース部材 62によって形成されている。  [0111] On the opposite side of the lens housing recess 66 in the longitudinal direction of the base member 62, a water absorption recess 68 is provided. The water-absorbing recess 68 is opened in the upper surface of the base member 62 in the same manner as the lens housing recess 66, and is formed in a substantially rectangular shape with a predetermined depth. Thus, the bottom 70 of the water absorbing recess 68 is formed by the base member 62.
[0112] さらに、吸水用凹所 68の底部 70には、例えば前記第三の実施形態における薬液 を含侵保持した吸水材層 54が載置されて、必要に応じて底面に固着されている。即 ち、本実施形態では、吸水用凹所 68の底部 70を形成するベース部材 62が、漏水防 止層として利用されており、それによつて、これらベース部材 62と吸水材層 54が協働 して本実施形態のコンタクトレンズ用吸水パッド 72を構成している。  [0112] Further, for example, the water absorbing material layer 54 impregnated and held with the chemical solution in the third embodiment is placed on the bottom portion 70 of the water absorbing recess 68, and is fixed to the bottom surface as necessary. . In other words, in this embodiment, the base member 62 forming the bottom 70 of the water absorbing recess 68 is used as a water leakage prevention layer, whereby the base member 62 and the water absorbing material layer 54 cooperate. Thus, the contact lens water absorbing pad 72 of the present embodiment is configured.
[0113] 更にまた、ベース部材 62の長手方向の中間部分には、上面に開口して長手方向 に延びる接続溝 74が設けられている。そして、接続溝 74の一方の端部がレンズ収容 凹所 66の開口部分に接続されている一方、接続溝 74の他方の端部が吸水用凹所 6 8の開口部分に接続されている。これにより、レンズ収容凹所 66と吸水用凹所 68が、 接続溝 74を通じて相互に連通されている。 [0113] Furthermore, a connection groove 74 that opens in the upper surface and extends in the longitudinal direction is provided in an intermediate portion in the longitudinal direction of the base member 62. One end of the connection groove 74 is connected to the opening of the lens housing recess 66, while the other end of the connection groove 74 is connected to the opening of the water absorption recess 68. As a result, the lens housing recess 66 and the water absorbing recess 68 They are communicated with each other through a connection groove 74.
[0114] また、ケース蓋シート 64は、ベース部材 62の外形形状に対応した平面形状を有し ており、例えばアルミニウム箔と合成樹脂の複合材からなるラミネートシートによって 形成されている。そして、ケース蓋シート 64は、図 8にも二点鎖線で示されているよう に、ベース部材 62の上端面に重ね合わされて、レンズ収容凹所 66の開口周縁部や 吸水用凹所 68の開口周縁部、更には接続溝 72の溝内略全面に亘つてヒートシール 等で剥離可能に固着されている。これにより、レンズ収容凹所 66の開口部や吸水用 凹所 68の開口部がケース蓋シート 64で覆蓋されて、レンズ収容凹所 66におけるコ ンタクトレンズ 38や保存液 26、吸水用凹所 68における吸水材層 54が密封されてい る。 [0114] The case lid sheet 64 has a planar shape corresponding to the outer shape of the base member 62, and is formed of, for example, a laminate sheet made of a composite material of aluminum foil and a synthetic resin. Then, the case lid sheet 64 is superimposed on the upper end surface of the base member 62 as shown by the two-dot chain line in FIG. 8 to form the peripheral edge of the opening of the lens housing recess 66 and the water absorbing recess 68. The outer peripheral portion of the opening and the substantially entire surface of the connection groove 72 are detachably fixed by heat sealing or the like. As a result, the opening of the lens housing recess 66 and the opening of the water absorbing recess 68 are covered with the case cover sheet 64, and the contact lens 38, the preservative solution 26, and the water absorbing recess 68 in the lens housing recess 66 are provided. The water absorbing material layer 54 is sealed.
[0115] このような構造とされた使い捨て型コンタクトレンズケース 60においては、コンタクト レンズ 38をレンズ収容凹所 66から取り出して装着する際に、例えば、以下のようにし て利用される。  [0115] In the disposable contact lens case 60 having such a structure, when the contact lens 38 is taken out from the lens housing recess 66 and mounted, for example, it is used as follows.
[0116] 先ず、ケース蓋シート 64をベース部材 62から剥離する。なお、かかる剥離に際して 、ケース蓋シート 64やベース部材 62の下方に前記第一の実施形態における吸水パ ッド 10等を配して、零れる保存液 26の飛散を防止するようにしても良い。  First, the case lid sheet 64 is peeled off from the base member 62. At the time of such peeling, the water absorbing pad 10 or the like in the first embodiment may be disposed below the case lid sheet 64 and the base member 62 to prevent the spilling preservation solution 26 from scattering.
[0117] そして、ケース蓋シート 64を剥離して、接続溝 74でレンズ収容凹所 66と吸水用凹 所 68を相互に接続せしめた状態で、吸水用凹所 68がレンズ収容凹所 66よりも下方 となるようにコンタクトレンズケース 60を傾斜させることにより、レンズ収容凹所 66に充 填された保存液 26の適当量を、接続溝 74を通じて吸水用凹所 68に流し込んで、吸 水用凹所 68の底部 70に配置された吸水材層 54に吸収保持させる。なお、この際に 、ケース蓋シート 64を、吸水用凹所 68側から剥離して、レンズ収容凹所 66がケース 蓋シート 64で覆われたままの状態とすることにより、保存液 26の零れ出しやコンタクト レンズ 38の落下等を防止することが出来る。  [0117] Then, the case cover sheet 64 is peeled off, and the lens housing recess 66 and the water absorption recess 68 are connected to each other by the connection groove 74. By tilting the contact lens case 60 so that it is also downward, the appropriate amount of the preservative solution 26 filled in the lens housing recess 66 is poured into the water absorbing recess 68 through the connection groove 74, and The water absorbing material layer 54 arranged at the bottom 70 of the recess 68 absorbs and retains the water. At this time, the case cover sheet 64 is peeled off from the water absorbing recess 68 side so that the lens housing recess 66 is kept covered by the case cover sheet 64, so that the preservation liquid 26 overflows. And the contact lens 38 can be prevented from falling out.
[0118] また、上述の如ぐ保存液 26を吸水材層 54に吸収させると共に、或いは吸収させ た後に、コンタクトレンズ 38を、指で上から押さえつけて、或いは摘んで、レンズ収容 凹所 66から取り出して装着する。  [0118] Further, as described above, the preservation solution 26 is absorbed into the water-absorbing material layer 54, or after the preservation solution 26 is absorbed, the contact lens 38 is pressed from above with a finger or pinched, and the contact lens 38 is removed from the lens accommodating recess 66.

[0119] このような本実施形態の使い捨て型コンタクトレンズケース 60においては、保存液 2 6に浸漬したコンタクトレンズ 38と本実施形態の吸水パッド 72を一体的に備えている ことにより、全体がコンパクト化されて、携帯便利性が有利に向上される。特に本実施 形態では、吸水パッド 72における漏水防止層としてベース部材 62が利用されている ことにより、構造が簡略化されると共に、より一層のコンパクトィ匕が図られ得る。 [0119] In the disposable contact lens case 60 of this embodiment, the preservative solution 2 Since the contact lens 38 immersed in 6 and the water-absorbing pad 72 of the present embodiment are integrally provided, the overall size is reduced, and the portability is advantageously improved. In particular, in the present embodiment, since the base member 62 is used as the water leakage prevention layer in the water absorption pad 72, the structure can be simplified and further compactness can be achieved.
[0120] さらに、本実施形態においては、レンズ収容凹所 66と吸水用凹所 68が接続溝 74 で相互に連通されていることにより、コンタクトレンズ 38を保存液 26から取り出す際に 、ベース部材 62を傾斜させること等によって、予め保存液 26を吸水用凹所 68に流し 込んで吸水材層 54に容易に吸収保持させることが可能であることから、コンタクトレン ズ 38の取り出し操作がより簡便に実現されるのである。また、保存液 26を含浸させた 吸水パッド 72にて、コンタクトレンズ 38を触る前に手指を拭うことも容易である。  Further, in the present embodiment, since the lens housing recess 66 and the water absorbing recess 68 are connected to each other through the connection groove 74, when the contact lens 38 is taken out of the storage solution 26, the base member is removed. By inclining 62, etc., the preservation solution 26 can be poured into the water absorbing recess 68 in advance and easily absorbed and retained in the water absorbing material layer 54, so that the operation of removing the contact lens 38 is easier. It is realized in. In addition, it is easy to wipe the finger before touching the contact lens 38 with the water absorbing pad 72 impregnated with the preservative solution 26.
[0121] 次に、図 9には、本発明の第五の実施形態としてのコンタクトレンズ用吸水パッド 10 と組み合わせて採用されるブリスター容器 80が示されてレ、る。このプリスター容器 80 は、吸水パッド 10と組み合わされることによって、コンタクトレンズ用吸水パッドセット 8 2の一部を構成する（図 10参照）。また、ブリスター容器 80は、例えば、前記第一の 実施形態に係るレンズ携帯用容器 14に収容されることにより、コンタクトレンズ用吸水 パッド 10やコンタクトレンズケース 12と共に携行可能とされ得る。  Next, FIG. 9 shows a blister container 80 employed in combination with the water-absorbing pad for contact lenses 10 according to the fifth embodiment of the present invention. The Plister container 80 forms a part of a contact lens water absorbing pad set 82 by being combined with the water absorbing pad 10 (see FIG. 10). Further, the blister container 80 may be carried with the contact lens water-absorbing pad 10 and the contact lens case 12, for example, by being accommodated in the lens portable container 14 according to the first embodiment.
[0122] 詳細には、処理液容器としてのブリスター容器 80は、容器本体 84とカバーシート 8 8を含んで形成されている。容器本体 84は、図 9中、上方に向かって開口する薄肉 の略カップ形状とされており、合成樹脂材等を用いて真空成形や圧空成形、射出成 形等により形成されている。そして、この容器本体 84のカップ状内には、処理液とし ての洗浄液 86が収容されている。  In detail, the blister container 80 as a processing liquid container is formed including a container body 84 and a cover sheet 88. In FIG. 9, the container body 84 has a thin, substantially cup shape that opens upward, and is formed by vacuum molding, pressure molding, injection molding, or the like using a synthetic resin material or the like. A cleaning liquid 86 as a processing liquid is stored in the cup shape of the container body 84.
[0123] この洗浄液 86としては、例えばソフトコンタクトレンズ (使い捨て型コンタクトレンズを 含む。）の洗浄に適用される、ポリへキサニドゃ界面活性剤等を適宜に含む溶液や、 或いはハードコンタクトレンズの洗浄に適用される、ポリビュルピロリドンや界面活性 剤、次亜塩素酸ナトリウム、臭化ナトリウム、ホウ酸緩衝剤、リン酸緩衝剤等を適宜に 含む溶液が、好適に採用され得る。特に本実施形態では、コンタクトレンズ 38を片目 一枚又は両目二枚洗浄するのに十分な容量の洗浄液 86が、容器本体 84に収容さ れている。 [0124] また、カバーシート 88は、合成樹脂や金属を積層したシート状の複合材等を用い て形成されていると共に、容器本体 84の開口面積よりも大きな外形寸法とされた薄 肉の平板形状を呈している。そして、カバーシート 88が、容器本体 84の開口部分を 覆蓋するようにして被せられて、該開口部の周囲において熱溶着等で剥離可能に固 着されている。これにより、ブリスター容器 80において、所定量の洗浄液 86が密封， 保持されている。また、洗浄液 86の使用時には、カバーシート 34を容器本体 84から 剥離すると共に、容器本体 84を適当に傾けて、開口部分から洗浄液 86を流し出す ことが出来るようになつている。この容器本体 84は、基本的に処理液保存にそのまま 再利用することは出来ないようになっており、使用後は、残った洗浄液と共に廃棄す ることを予定している。 [0123] As the cleaning liquid 86, for example, a solution appropriately containing polyhexanide / surfactant, or a cleaning solution for hard contact lenses, which is applied to cleaning of soft contact lenses (including disposable contact lenses). A solution which appropriately contains polybutylpyrrolidone, a surfactant, sodium hypochlorite, sodium bromide, a borate buffer, a phosphate buffer and the like, which is applied to the above, can be suitably adopted. Particularly, in the present embodiment, the container body 84 contains a sufficient amount of the cleaning liquid 86 for cleaning one contact lens or one contact lens 38 in both eyes. [0124] The cover sheet 88 is formed using a sheet-like composite material in which synthetic resin or metal is laminated, and is a thin flat plate whose external dimensions are larger than the opening area of the container body 84. It has a shape. Then, a cover sheet 88 is covered so as to cover the opening of the container body 84, and is fixed so as to be peelable around the opening by heat welding or the like.
