Description

本発明は、取り出し性に優れたコンタクトレンズ用容器に関する。 The present invention relates to a contact lens container excellent in take-out property.

最近では、コンタクトレンズを市場へ流通する際、個別にコンタクトレンズを包装したブリスター容器が用いられている。 Recently, blister containers in which contact lenses are individually packaged are used when distributing contact lenses to the market.

一般的なブリスター容器は、コンタクトレンズとその保存液を収容する半球状の窪み部と、その開口部周辺に広がるフランジ部と、を有する合成樹脂製の本体部と、ポリプロピレンフィルムとアルミ箔の積層物からなる蓋部で構成されており、本体部と蓋部のシールには、加熱又は超音波による溶着方法が用いられている。 A general blister container has a synthetic resin main body having a contact lens and a hemispherical recess for storing the storage solution, and a flange extending around the opening, and a laminate of polypropylene film and aluminum foil. It is comprised by the cover part which consists of a thing, and the welding method by a heating or an ultrasonic wave is used for the seal | sticker of a main-body part and a cover part.

このブリスター容器からコンタクトレンズを取り出す方法として、掌に保存液ごと出したコンタクトレンズを指先で摘む方法があるが、この方法では、コンタクトレンズが流失する危険性を有していると共に、摘み上げる際にコンタクトレンズが折り曲げられるため、レンズの光学特性に悪影響を及ぼしたり、レンズ表面に傷を発生させたりすることが懸念される。また、蓋部を本体部から引き剥がし、ブリスター容器を開封した後に、窪み部に手指を入れて指先でコンタクトレンズをすくい上げる方法も一般的に行われているが、指先ですくい上げ、コンタクトレンズを取り出す過程で、蓋部を本体部から引き剥がす際に発生する溶着部の剥がれ跡にコンタクトレンズが接触する可能性が高く、レンズを傷付ける恐れがある。 As a method of taking out the contact lens from the blister container, there is a method of picking the contact lens taken out of the storage solution on the palm with a fingertip. However, in this method, there is a risk that the contact lens may be washed away. Since the contact lens is bent, the optical characteristics of the lens may be adversely affected, or the lens surface may be scratched. Also, it is common practice to peel off the lid from the main body, open the blister container, and then put your fingers into the dent and scoop up the contact lens with your fingertips. In the process, there is a high possibility that the contact lens will come in contact with the trace of the welded portion that is generated when the lid portion is peeled off from the main body portion, and the lens may be damaged.

コンタクトレンズ表面の傷は、擦り洗い時に破損の原因となったり、そこに汚れが蓄積しやすいことから、装用感や視力補正性の低下を引き起こす原因となったりするため、好ましくない。 Scratches on the surface of the contact lens are not preferable because they cause damage during scrubbing, and dirt tends to accumulate there, causing a feeling of wearing and a reduction in visual acuity correction.

さらに、窪み部に手指を入れて指先ですくい上げる方法においては、指ですくい上げる際、装用時に角膜に接するコンタクトレンズのベースカーブ面に手指が接触するため、手指に付着した汚れや細菌によってコンタクトレンズが汚染される恐れがある。特に、手指の洗浄が不十分な場合には、この汚染を原因とした眼疾患を誘発する危険性も懸念される。 Furthermore, in the method of putting a finger in the depression and scooping it up with the fingertip, the finger touches the base curve surface of the contact lens that touches the cornea when worn, so that the contact lens is contaminated by dirt and bacteria attached to the finger. There is a risk of contamination. In particular, when the fingers are not sufficiently washed, there is a concern about the risk of inducing eye diseases caused by this contamination.

これに対し、流通時のコンタクトレンズの保持性を向上すると共に、装用時のコンタクトレンズのベースカーブ面への手指の接触を抑止するようにしたコンタクトレンズ用パッケージが知られている（特許文献１参照）。この特許文献１に記載のコンタクトレンズ用パッケージは、コンタクトレンズとスプリングディスクをコンタクトレンズのカップの深さ（サジタルデプス）よりも浅いブリスター容器の収容空間において収容シートに挟み込み、コンタクトレンズが押圧された状態で収納されており、収容シートの開封により押圧されない状態に戻る際に、コンタクトレンズを元の形状に戻す補助をするようになっている。 On the other hand, there is known a contact lens package that improves the retention of a contact lens during distribution and prevents the finger from contacting the base curve surface of the contact lens during wearing (Patent Document 1). reference). In the contact lens package described in Patent Document 1, the contact lens and the spring disk are sandwiched between the accommodation sheets in the accommodation space of the blister container shallower than the contact lens cup depth (sagittal depth), and the contact lens is pressed. The contact lens is stored in a state, and when returning to a state where it is not pressed by opening the storage sheet, the contact lens is returned to its original shape.

また、流通時のコンタクトレンズの保持性を向上するために、凹状内面を有する第一部材と、凸状内面を有する第二部材とを重ね合わせた際に生じる対向内面間にコンタクトレンズを保持し、当該部材を保存液と共に収容するコンタクトレンズ流通ケースも開示されている（特許文献２参照）。 Further, in order to improve the retention of the contact lens during distribution, the contact lens is held between the opposed inner surfaces generated when the first member having the concave inner surface and the second member having the convex inner surface are overlapped. A contact lens distribution case that houses the member together with a preservative is also disclosed (see Patent Document 2).

特開２００５−２５０４９６号公報JP 2005-250496 A 再表２００９−０６９２６４号公報Table 2009-069264

特許文献１に記載のコンタクトレンズ用パッケージは、コンタクトレンズのカップの深さよりも浅いブリスター容器に、コンタクトレンズがスプリングディスクと共に挟み込まれて押圧された状態で保存されるため、収容シートからの外部応力によるコンタクトレンズの光学特性への悪影響や形状不良、また、コンタクトレンズのスプリングディスクとの接触部に傷が発生しやすいという、新たな問題が危惧される。 Since the contact lens package described in Patent Document 1 is stored in a blister container that is shallower than the depth of the contact lens cup in a state where the contact lens is sandwiched and pressed together with the spring disk, external stress from the storage sheet is stored. There are concerns about new problems such as the adverse effects on the optical characteristics of the contact lens and the poor shape caused by the contact lens, and the contact lens with the spring disk is likely to be damaged.

特許文献２に記載のコンタクトレンズ流通ケースは、コンタクトレンズの形状を保持したまま収納されるものの、第一部材と第二部材を重ね合わせる際に、コンタクトレンズを挟み込むことが危惧される上、構造が複雑になる。また、保存液の液量を少なくした流通ケースでは、保存液の液量が極端に少なく、移送時の傾きにより、コンタクトレンズの一部或いは大半が液中に浸漬されない場合が考えられ、乾燥による光学特性への悪影響が生じる恐れがある。 Although the contact lens distribution case described in Patent Document 2 is stored while retaining the shape of the contact lens, there is a concern that the contact lens may be sandwiched when the first member and the second member are overlapped, and the structure is It becomes complicated. In addition, in the distribution case where the amount of the preservation solution is reduced, the amount of the preservation solution is extremely small, and a part or most of the contact lens may not be immersed in the solution due to the inclination during transfer. There is a risk of adverse effects on optical properties.

また、特許文献１に記載のコンタクトレンズ用パッケージ及び特許文献２に記載のコンタクトレンズ流通ケースは、いずれもコンタクトレンズが２枚のシート状体に挟まれて収容されているために、開封と同時にコンタクトレンズが露出するから、開封時に誤ってコンタクトレンズを落下させる恐れもある。 Moreover, since the contact lens package described in Patent Document 1 and the contact lens distribution case described in Patent Document 2 are both housed by being sandwiched between two sheet-like bodies, they are simultaneously opened. Since the contact lens is exposed, the contact lens may be accidentally dropped when opened.

そこで、本願発明は、取り出し時や収納時にコンタクトレンズに傷を発生させないと共に、コンタクトレンズの光学特性に影響を及ぼさないコンタクトレンズ用容器を提供することを目的とする。 SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a contact lens container that does not cause damage to the contact lens when taken out or stored, and that does not affect the optical characteristics of the contact lens.

引き上げ機構５は、蓋部４を閉じたときに、蓋部４から窪み部１０に向かって突出するように設けた係止部６と、この係止部６と係合可能にコンタクトレンズ保持部材２に設けた被係止部７と、を有している。係止部６は、一端が蓋部４の下面に固定されており、窪み部１０に向かって斜めに下方に延設され、他端が上方に湾曲したフック形状を成している。係止部６は、熱溶着、超音波溶着、高周波溶着などの溶着方法や接着剤、溶剤などによる接着方法によって蓋部４に固定できる他、蓋部４と一体成形してもよい。被係止部７も、係止部６と同様に、溶着や接着によってコンタクトレンズ保持部材２に固定することができるが、成形性や引き上げ時の安定性の観点から、被係止部７はコンタクトレンズ保持部材２と一体成形してあることが好ましい。 The lifting mechanism 5 includes a locking portion 6 provided so as to protrude from the lid portion 4 toward the recessed portion 10 when the lid portion 4 is closed, and a contact lens holding member engageable with the locking portion 6. 2 to be engaged. One end of the locking portion 6 is fixed to the lower surface of the lid portion 4, extends obliquely downward toward the recessed portion 10, and has a hook shape with the other end curved upward. The locking part 6 can be fixed to the lid part 4 by a welding method such as thermal welding, ultrasonic welding, high-frequency welding or the like, or an adhesion method using an adhesive, a solvent, or the like, or may be integrally formed with the lid part 4. Similarly to the locking portion 6, the locked portion 7 can be fixed to the contact lens holding member 2 by welding or adhesion, but from the viewpoint of moldability and stability at the time of lifting, the locked portion 7 is It is preferable that the contact lens holding member 2 is integrally molded.

コンタクトレンズ保持部材２は、レンズ載置部３を有するコンタクトレンズ保持部材２を容器本体部１の底部（容器底部１３）に定置するための安定部１７を備え、被係止部７と安定部１７がそれぞれレンズ載置部３に連結して設けられている。本発明のコンタクトレンズ用容器は、コンタクトレンズ９の保存中においては、安定部１７によってコンタクトレンズ保持部材２が容器底部１３に定置され、開蓋時においては、引き上げ機構５によってコンタクトレンズ保持部材２が容器本体部１に対して可動式になっている。 The contact lens holding member 2 includes a stabilizing portion 17 for placing the contact lens holding member 2 having the lens mounting portion 3 on the bottom portion (container bottom portion 13) of the container main body portion 1, and includes the locked portion 7 and the stabilizing portion. 17 are respectively connected to the lens mounting portion 3. In the contact lens container of the present invention, when the contact lens 9 is stored, the contact lens holding member 2 is placed on the container bottom 13 by the stabilizing portion 17, and when the lid is opened, the contact lens holding member 2 is moved by the lifting mechanism 5. Is movable with respect to the container body 1.

安定部１７は、矩形状の容器底部１３の一辺と係合する棒状体を成し、レンズ載置部３の底部に連結して一体的に形成されている。被係止部７は、レンズ載置部３に対して安定部１７と同じ側に設けられ、レンズ載置部３の周縁部から斜め上方に向かって突出して形成されている。被係止部７は、レンズ載置部３の周縁部と環状体を成すように形成され、係止部６と係合可能にしてある。コンタクトレンズ保持部材２は、蓋部４の開蓋時に、蓋部４に固定されて窪み部１０方向に突出した係止部６が、被係止部７に接して係合するように構成されることにより、開蓋に連動して引き上げられるから、図５に示すようにレンズ載置部３が上方に移動して保存液中より持ち上がる。 The stabilizing portion 17 forms a rod-like body that engages with one side of the rectangular container bottom portion 13, and is integrally connected to the bottom portion of the lens placement portion 3. The locked portion 7 is provided on the same side as the stabilizing portion 17 with respect to the lens placement portion 3 and is formed to project obliquely upward from the peripheral edge of the lens placement portion 3. The locked portion 7 is formed so as to form an annular body with the peripheral edge portion of the lens mounting portion 3, and can be engaged with the locking portion 6. The contact lens holding member 2 is configured such that when the lid portion 4 is opened, a locking portion 6 that is fixed to the lid portion 4 and protrudes in the direction of the recessed portion 10 contacts and engages with the locked portion 7. Accordingly, the lens mounting portion 3 is moved upward and lifted from the preservation solution as shown in FIG.

なお、係止部６及び被係止部７は、開蓋時に係合可能に形成してあればよく、図示の態様に限定されるものではない。また、安定部１７は、コンタクトレンズ９の保存中に、コンタクトレンズ保持部材２が容器底部１３に対して回転したり移動したりして、被係止部７が係止部６と係合可能な位置からずれるのを防止することができるように構成してあればよい。したがって、安定部１７は、被係止部７と反対側に設けることもでき、被係止部７と同じ側及び反対側の双方に設けてもよい。 In addition, the latching | locking part 6 and the to-be-latched part 7 should just be formed so that engagement is possible at the time of lid opening, and are not limited to the aspect of illustration. Further, during the storage of the contact lens 9, the stabilizing portion 17 can be engaged with the locking portion 6 by the contact lens holding member 2 rotating or moving with respect to the container bottom portion 13. What is necessary is just to be comprised so that it may prevent shifting from a proper position. Therefore, the stabilizing portion 17 can be provided on the opposite side to the locked portion 7, or may be provided on both the same side and the opposite side as the locked portion 7.

本コンタクトレンズ用容器において、コンタクトレンズ保持部材２は、コンタクトレンズ９の取り出し時に、レンズ載置部３の全体又は大部分が保存液の液面より持ち上がるような可動式であればよい。コンタクトレンズ保持部材２は、蓋部４及び係止部６との一体成形による連結態様、蓋部４及び係止部６とコンタクトレンズ保持部材２を独立成形後に被係止部７において溶着又は嵌合した連結態様、或いは、各々独立したままの態様が考えられ得る。本発明においては、成形性及び可動性などを考慮して、図示の第一態様のように、蓋部４及び係止部６とコンタクトレンズ保持部材２の各々が独立していることが好ましい。 In this contact lens container, the contact lens holding member 2 may be movable so that the whole or most of the lens mounting portion 3 is lifted from the liquid surface of the storage liquid when the contact lens 9 is taken out. The contact lens holding member 2 is formed by integrally molding the lid portion 4 and the locking portion 6, and the lid portion 4, the locking portion 6 and the contact lens holding member 2 are welded or fitted in the locked portion 7 after independent molding. Combined connection modes or modes that remain independent of each other can be envisaged. In the present invention, in consideration of moldability, mobility, and the like, it is preferable that the lid portion 4 and the locking portion 6 and the contact lens holding member 2 are independent as in the illustrated first embodiment.

本発明のコンタクトレンズ用容器において、コンタクトレンズ９は、ベースカーブ面に手指が接触しないように、フロントカーブ面を上方にしてレンズ載置部３に載置されることが好ましい。レンズ載置部３は、コンタクトレンズ保持部材２において上方に突出する球面形状に形成されており、コンタクトレンズ９のベースカーブと同様の曲率を有していることが好ましい。さらに、移送時や保存時のコンタクトレンズ９の移動を抑止するために、コンタクトレンズ保持部材２は、窪み部１０内の容器底部１３に安定して収容されていることが重要である。一つの手段として、コンタクトレンズ保持部材２におけるレンズ載置部３を複数の貫通孔を有した形状とすることが挙げられる。レンズ載置部３が当該形状を採用することにより、保存液が充填された窪み部１０内にコンタクトレンズ保持部材２を収容する際に、内側に保存液や空気を閉じ込めることがないため、コンタクトレンズ保持部材２が浮遊することなく容器底部１３に接した定位置で安定することができる。 In the contact lens container of the present invention, the contact lens 9 is preferably placed on the lens placement portion 3 with the front curve surface facing upward so that fingers do not contact the base curve surface. The lens mounting portion 3 is formed in a spherical shape protruding upward in the contact lens holding member 2, and preferably has a curvature similar to the base curve of the contact lens 9. Furthermore, in order to suppress the movement of the contact lens 9 during transfer or storage, it is important that the contact lens holding member 2 is stably accommodated in the container bottom 13 in the recess 10. One means is to form the lens mounting portion 3 of the contact lens holding member 2 into a shape having a plurality of through holes. Since the lens mounting portion 3 adopts the shape, when the contact lens holding member 2 is accommodated in the recess portion 10 filled with the storage liquid, the storage liquid or air is not confined inside. The lens holding member 2 can be stabilized at a fixed position in contact with the container bottom 13 without floating.

レンズ載置部３は、具体的な形状の一態様として、図２に示すように、曲面の頂点部となる中心部に環状部１５を有し、この環状部１５より放射状に延伸した骨部１６を有する。骨部１６は、コンタクトレンズ９のベースカーブと同様の曲率を有している。また、コンタクトレンズ９の安定性を考慮し、骨部１６の本数は４以上１２以下に形成されていることが好ましく、左右対称となるように偶数本配することがより好ましい。 As shown in FIG. 2, the lens placement portion 3 has an annular portion 15 at the center that becomes the apex portion of the curved surface, and a bone portion that extends radially from the annular portion 15 as one aspect of a specific shape. 16 The bone part 16 has the same curvature as the base curve of the contact lens 9. In consideration of the stability of the contact lens 9, the number of the bone portions 16 is preferably 4 or more and 12 or less, and more preferably an even number so as to be symmetrical.

容器底部１３の横幅は、コンタクトレンズ保持部材２を容器本体部１の底部に接して安定的に収容するために、レンズ載置部３の横幅ｈ（図４参照）より大きく設けることが好ましい。この窪み部１０の横幅は、レンズ載置部３の横幅ｈに合わせることで、移送時及び保存時のレンズ載置部３の安定性を向上させることが可能となる。 The lateral width of the container bottom 13 is preferably larger than the lateral width h (see FIG. 4) of the lens mounting portion 3 in order to stably accommodate the contact lens holding member 2 in contact with the bottom of the container body 1. The stability of the lens mounting part 3 during transfer and storage can be improved by adjusting the horizontal width of the hollow part 10 to the horizontal width h of the lens mounting part 3.

図１及び図２において、１４はズレ防止部であり、コンタクトレンズ９がレンズ載置部３からズレ落ちるのを防止している。ズレ防止部１４は、図示の実施例のように、安定部１７を設けた側及びその反対側に設けることにより、引き上げ機構５によってコンタクトレンズ保持部材２が引き上げられて、レンズ載置部３が保存液から持ち上げられる際に、コンタクトレンズ９がズレ落ちるのを確実に防止することができる。 In FIG. 1 and FIG. 2, reference numeral 14 denotes a displacement prevention unit, which prevents the contact lens 9 from falling off the lens placement unit 3. As shown in the illustrated embodiment, the displacement prevention unit 14 is provided on the side where the stabilization unit 17 is provided and on the opposite side, whereby the contact lens holding member 2 is pulled up by the lifting mechanism 5 and the lens mounting unit 3 is moved. It is possible to reliably prevent the contact lens 9 from slipping off when being lifted from the storage solution.

被係止部７は、レンズ載置部３と連結して一体成形されており、図３に示すように、上方へ延伸した構造を有する。レンズ載置部３の底辺（容器底部１３）に対する被係止部７の角度ｅは、１°〜９０°で形成されることが好ましく、被係止部７の長さに係るコンタクトレンズ保持部材２の安定性の面から４５°〜８０°に形成することがより好ましい。また、被係止部７の長さが、窪み部１０の深さを決定することとなる。被係止部７の長さが長すぎる場合、窪み部１０を深く形成しなければならず、窪み部１０の容積が大きくなることで、保存液中でレンズ載置部３やコンタクトレンズ９が移動しやすくなり、移送時や保存時にコンタクトレンズ９を定位置に保持することが困難になる。一方、被係止部７の長さが短すぎる場合、開蓋時に係止部６を被係止部７と係合させ、コンタクトレンズ保持部材２を引き上げる際の安定性が低下する。このため、被係止部７の長さは、図３において、コンタクトレンズ保持部材２の高さｃに対し、被係止部７の高さｄが８０〜１３０％となるように形成されていることが好ましい。さらに好ましくは、窪み部１０の深さと、被係止部７の高さｄが等しくなる状態であり、当該構成とすることで、コンタクトレンズ保持部材２は、蓋部４に抑えられ、移送時の安定性が向上する。また、コンタクトレンズ９の取り出し時において、図５に示すようにレンズ載置部３が持ち上げられた状態におけるバランス性を考慮し、レンズ載置部３と被係止部７とは二点で連結するように形成することが好ましい。被係止部７は、この二点の連結部をレンズ載置部３に対して左右対照となるように配することで、バランス性をさらに向上させることが可能となる。図４に示すように、被係止部７は、この二点間の距離ｆをレンズ載置部３の横幅ｈよりも小さく形成することで、コンタクトレンズ９を取り出す開蓋時に、係止部６によって被係止部７を引き上げる際の力が加わり易くなる。 The locked portion 7 is integrally formed with the lens mounting portion 3 and has a structure extending upward as shown in FIG. The angle e of the locked portion 7 with respect to the bottom side (container bottom portion 13) of the lens placement portion 3 is preferably formed at 1 ° to 90 °, and the contact lens holding member according to the length of the locked portion 7 From the viewpoint of stability of 2, it is more preferable to form it at 45 ° to 80 °. Further, the length of the locked portion 7 determines the depth of the recessed portion 10. When the length of the locked portion 7 is too long, the dent portion 10 must be formed deeply, and the volume of the dent portion 10 is increased, so that the lens placement portion 3 and the contact lens 9 are kept in the storage solution. It becomes easy to move, and it becomes difficult to hold the contact lens 9 in a fixed position during transfer or storage. On the other hand, when the length of the locked portion 7 is too short, the stability when the contact lens holding member 2 is pulled up by engaging the locking portion 6 with the locked portion 7 when the lid is opened is lowered. Therefore, the length of the locked portion 7 is formed such that the height d of the locked portion 7 is 80 to 130% with respect to the height c of the contact lens holding member 2 in FIG. Preferably it is. More preferably, the depth of the recessed portion 10 and the height d of the locked portion 7 are equal to each other. With this configuration, the contact lens holding member 2 is suppressed by the lid portion 4 and is transferred. Improves stability. Further, when the contact lens 9 is taken out, the lens mounting part 3 and the locked part 7 are connected at two points in consideration of the balance when the lens mounting part 3 is lifted as shown in FIG. It is preferable to form so as to. The to-be-latched part 7 can further improve the balance by arranging the two connecting parts so as to be in contrast with the lens mounting part 3. As shown in FIG. 4, the locked portion 7 is formed so that the distance f between the two points is smaller than the lateral width h of the lens mounting portion 3, so that the locking portion 7 is opened when the contact lens 9 is opened. 6 makes it easy to apply a force when pulling up the locked portion 7.

安定部１７は、レンズ載置部３と連結して一体成形されており、レンズ載置部３の底部より水平方向へ延伸した構造を有する。図３において、安定部１７とレンズ載置部３の全長の合計であるコンタクトレンズ保持部材２の全長ｂが、窪み部１０の容器底部１３の全長を決定することとなる。容器底部１３の全長は、コンタクトレンズ保持部材２を容器本体部１の底部に接して安定的に収容するために、コンタクトレンズ保持部材２の全長ｂより大きくすることが好ましい。また、容器底部１３の全長は、コンタクトレンズ保持部材２の全長ｂと合わせることにより、移送時及び保存時のコンタクトレンズ保持部材２の安定性を向上させることができる。安定部１７が長すぎる場合、係止部６によって被係止部７を引き上げ、コンタクトレンズ保持部材２全体を保存液中より持ち上げる際に、安定部１７の端部が容器本体部１の周縁に引っ掛かり、充分にレンズ載置部３を引き上げることができなくなる。このため、コンタクトレンズ保持部材２の全長ｂは、レンズ載置部３の全長ａに対し、１１０〜１５０％となるように形成されていることが好ましい。また、窪み部１０へ収容された際のコンタクトレンズ保持部材２の安定性を考慮し、レンズ載置部３と安定部１７とは二点で連結するように形成することが好ましい。安定部１７は、この二点の連結部をレンズ載置部３に対して左右対照となるように配することで、安定性をさらに向上させることが可能となる。図４に示すように、安定部１７は、この二点間の距離ｇをレンズ載置部３の横幅ｈと同じ幅に形成することで、移送時及び保存時の安定性並びにコンタクトレンズ保持部材２を引き上げる際のガイドとしての効果が向上する。 The stabilizing portion 17 is integrally formed with the lens placement portion 3 and has a structure extending in the horizontal direction from the bottom of the lens placement portion 3. In FIG. 3, the total length b of the contact lens holding member 2, which is the total length of the stable portion 17 and the lens mounting portion 3, determines the total length of the container bottom portion 13 of the recess portion 10. The total length of the container bottom 13 is preferably larger than the total length b of the contact lens holding member 2 in order to stably accommodate the contact lens holding member 2 in contact with the bottom of the container main body 1. Moreover, the stability of the contact lens holding member 2 at the time of transfer and storage can be improved by matching the total length of the container bottom 13 with the full length b of the contact lens holding member 2. When the stable part 17 is too long, when the locked part 7 is pulled up by the locking part 6 and the entire contact lens holding member 2 is lifted from the preservation solution, the end of the stable part 17 is placed on the periphery of the container body 1. As a result, the lens mounting portion 3 cannot be pulled up sufficiently. For this reason, it is preferable that the total length b of the contact lens holding member 2 is formed to be 110 to 150% with respect to the total length a of the lens placement portion 3. In consideration of the stability of the contact lens holding member 2 when housed in the recess 10, it is preferable to form the lens mounting portion 3 and the stabilizing portion 17 so as to be connected at two points. The stability unit 17 can further improve the stability by arranging the two connecting portions so as to be contrasted with respect to the lens placement unit 3. As shown in FIG. 4, the stabilizing portion 17 forms the distance g between the two points to the same width as the lateral width h of the lens mounting portion 3, so that the stability at the time of transfer and storage and the contact lens holding member The effect as a guide when pulling up 2 is improved.

コンタクトレンズ保持部材２は、被係止部７及び安定部１７が容器本体部１と蓋部４の連結部２０側に位置するように、容器本体部１の窪み部１０内に収容されている。コンタクトレンズ９を取り出す際には、蓋部４のフック部１８と容器本体部１のフランジ部１１との係合を外し、このフランジ部１１を手指で摘まんで蓋部４を開蓋操作することで、係止部６と被係止部７が係合し、コンタクトレンズ保持部材２が安定部１７にガイドされて安定的に引き上げられ、レンズ載置部３を保存液中から確実に持ち上げることができる。また、窪み部１０は、連結部２０側の側壁を対向する側壁と比べて緩やかな傾斜に形成することで、安定部１７がこの側壁に沿って引き上げられるから、コンタクトレンズ保持部材２を更に安定して引き上げることができる。 The contact lens holding member 2 is accommodated in the recessed portion 10 of the container main body 1 so that the locked portion 7 and the stabilizing portion 17 are located on the connecting portion 20 side of the container main body 1 and the lid 4. . When the contact lens 9 is taken out, the hook portion 18 of the lid portion 4 and the flange portion 11 of the container body portion 1 are disengaged, and the lid portion 4 is opened by grasping the flange portion 11 with fingers. Thus, the locking portion 6 and the locked portion 7 are engaged, and the contact lens holding member 2 is guided by the stable portion 17 and is stably pulled up, so that the lens mounting portion 3 is reliably lifted from the storage solution. Can do. In addition, the recess 10 is formed with a gentler slope on the side wall on the connecting part 20 side than the opposite side wall, so that the stabilizing part 17 is pulled up along this side wall, so that the contact lens holding member 2 is further stabilized. Can be raised.

容器本体部１及びコンタクトレンズ保持部材２は、成形性や液密性がよいことから合成樹脂で形成してある。容器本体部１及びコンタクトレンズ保持部材２に用いる合成樹脂は、コンタクトレンズ９と保存液を封入した後に滅菌工程を行う必要があるので、オートクレーブ滅菌に耐えうる程度の耐熱性や耐薬品性を有するものが好ましい。一般的には、ポリエチレン、ポリプロピレン、脂環式ポリオレフィン、ポリエチレンテレフタレート、ポリブチレンテレフタレート、ポリカーボネート、熱可塑性エラストマー等が挙げられる。本発明のコンタクトレンズ用容器においては、取扱いの簡便性から、容器本体部１及びコンタクトレンズ保持部材２の双方ともにポリプロピレンが最も好ましく用いられる。さらに、本容器は、耐熱性を有する生分解性の樹脂を使用することで、使用後の廃棄処理を容易にするという利点も得られる。 The container body 1 and the contact lens holding member 2 are made of synthetic resin because of good moldability and liquid tightness. Since the synthetic resin used for the container body 1 and the contact lens holding member 2 needs to be sterilized after sealing the contact lens 9 and the preservation solution, it has heat resistance and chemical resistance enough to withstand autoclave sterilization. Those are preferred. In general, polyethylene, polypropylene, alicyclic polyolefin, polyethylene terephthalate, polybutylene terephthalate, polycarbonate, thermoplastic elastomer, and the like can be given. In the contact lens container of the present invention, polypropylene is most preferably used for both the container main body 1 and the contact lens holding member 2 because of easy handling. Furthermore, this container also has the advantage of facilitating disposal after use by using a biodegradable resin having heat resistance.

蓋部４及び引き上げ機構５に用いる合成樹脂は、容器本体部１、コンタクトレンズ保持部材２と同様に、オートクレーブ滅菌に耐えうる程度の耐熱性や耐薬品性を有することが好ましく、また、溶着性を考慮すると、容器本体部１と同一の合成樹脂を用いることが特に好ましい。 The synthetic resin used for the lid portion 4 and the lifting mechanism 5 preferably has heat resistance and chemical resistance that can withstand autoclave sterilization, as well as the container body portion 1 and the contact lens holding member 2, and has weldability. In view of the above, it is particularly preferable to use the same synthetic resin as that of the container body 1.

第一態様のコンタクトレンズ用容器は、蓋部４が開閉自在に設けられていることから、出荷用容器に限られず、保存用容器としても使用することができる。 The contact lens container according to the first aspect is not limited to a shipping container, and can be used as a storage container because the lid 4 is provided so as to be freely opened and closed.

［容器の第二態様］
図６は、本発明のコンタクトレンズ用容器の第二態様を示す断面図である。また、図７は、本発明の第二態様を示す平面図である。 [Second embodiment of container]
FIG. 6 is a cross-sectional view showing a second embodiment of the contact lens container of the present invention. FIG. 7 is a plan view showing a second embodiment of the present invention.

容器本体部１は、コンタクトレンズ９及び保存液を収容する窪み部１０を有しており、窪み部１０内にはレンズ載置部３を有するコンタクトレンズ保持部材２が収容されている。また、容器本体部１は、窪み部１０の周囲にフランジ部１１を形成してある。容器本体部１の一方には、フランジ部１１より僅かに高さが低い容器把持部１２を延設してあり、蓋部４を開封したりコンタクトレンズ９を取り出したりする際に容器本体部１を把持しやすくしてある。容器本体部１及びコンタクトレンズ保持部材２の他の構成は、第一態様と同様である。 The container body 1 includes a contact lens 9 and a recess 10 for storing a storage solution, and a contact lens holding member 2 having a lens placement portion 3 is stored in the recess 10. Further, the container main body 1 has a flange 11 formed around the recess 10. On one side of the container main body 1, a container gripping portion 12 that is slightly lower in height than the flange portion 11 is extended, and the container main body 1 is opened when the lid 4 is opened or the contact lens 9 is taken out. It is easy to grip. Other configurations of the container main body 1 and the contact lens holding member 2 are the same as in the first aspect.

第二態様のコンタクトレンズ用容器において、蓋部４は、開封時に、蓋部４の全体が取り除き可能な一体のシート構造により形成されたシートタイプ、又は、窪み部１０の開口部のみが取り除き可能なプルトップ構造により形成されたプルトップタイプなど、窪み部１０を密閉可能な種々の構成を採用することができる。シートタイプを採用した場合に、蓋部４は、ポリプロピレンとアルミ箔の積層物や合成樹脂により形成される。本願発明においては、各部の形成性を考慮し、蓋部４に合成樹脂を好ましく用い、射出成型により形成することができる。蓋部４に用いる合成樹脂は、容器本体部１、コンタクトレンズ保持部材２と同様に、オートクレーブ滅菌に耐えうる程度の耐熱性や耐薬品性を有することが好ましく、また、密閉時の容器本体部１との溶着性を考慮すると、容器本体部１と同一の合成樹脂を用いることが特に好ましい。 In the contact lens container according to the second aspect, the lid 4 can be removed only by a sheet type formed by an integral sheet structure in which the entire lid 4 can be removed or the opening of the recess 10 when opened. Various configurations capable of sealing the recessed portion 10 such as a pull top type formed by a simple pull top structure can be employed. When the sheet type is adopted, the lid 4 is formed of a laminate of polypropylene and aluminum foil or a synthetic resin. In the present invention, considering the formability of each part, a synthetic resin is preferably used for the lid part 4 and can be formed by injection molding. The synthetic resin used for the lid 4 is preferably heat and chemical resistant to the extent that it can withstand autoclave sterilization, similar to the container body 1 and the contact lens holding member 2, and the container body when sealed. In view of the weldability with 1, it is particularly preferable to use the same synthetic resin as that of the container body 1.

図６に示す容器は、蓋部４がシートタイプのものであり、通常のブリスター容器と同様に、窪み部１０周辺のフランジ部１１において蓋部４と容器本体部１とを溶着することにより密閉される。蓋部４は、容器本体部１との溶着部位がフランジ部１１に連続する容器把持部１２まで至ると、蓋部４の開封性が低下するため好ましくない。蓋部４と容器本体部１の接合には、熱溶着、超音波溶着、高周波溶着などの通常のプラスチックの溶着方法を用いることができ、蓋部４と容器本体部１の材質によっては接着剤や溶剤による接着方法を用いることも可能であるが、熱溶着を用いることが最も好ましい。 The container shown in FIG. 6 has a lid portion 4 of a sheet type, and is sealed by welding the lid portion 4 and the container main body portion 1 at the flange portion 11 around the recessed portion 10 in the same manner as a normal blister container. Is done. When the cover part 4 reaches the container gripping part 12 where the welded part with the container main body part 1 continues to the flange part 11, the unsealing property of the cover part 4 is lowered, which is not preferable. For joining the lid portion 4 and the container main body portion 1, an ordinary plastic welding method such as thermal welding, ultrasonic welding, or high frequency welding can be used. Depending on the material of the lid portion 4 and the container main body portion 1, an adhesive is used. It is possible to use a bonding method using a solvent or a solvent, but it is most preferable to use heat welding.

蓋部４にプルトップ構造を採用した場合においては、合成樹脂製のシートタイプを採用した場合と同一の事由により、容器本体部１と同一の合成樹脂で形成してあることが好ましく、射出成型により形成することができる。 In the case of adopting a pull-top structure for the lid part 4, it is preferably formed of the same synthetic resin as the container body part 1 for the same reason as when a synthetic resin sheet type is adopted. Can be formed.

第二態様のコンタクトレンズ用容器において、引き上げ機構５は、蓋部４を閉じたときに、蓋部４から窪み部１０に向かって突出するように設けた係止部６と、この係止部６と係合するようにコンタクトレンズ保持部材２に設けた被係止部７と、係止部６と被係止部７とを連結するヒンジ機構８と、を有している。ヒンジ機構８は、連結部に回転軸を有する構成の他、連結部を折り曲げ自在に形成した構成にしてもよい。第二態様の引き上げ機構５は、断面が「く」の字状に構成してあり、レンズ載置部３を上方に引き上げやすくしてある。引き上げ機構５の他の構成は、第一態様と同様である。 In the contact lens container according to the second aspect, the lifting mechanism 5 includes a locking portion 6 provided so as to protrude from the lid portion 4 toward the hollow portion 10 when the lid portion 4 is closed, and the locking portion. The contact lens holding member 2 is engaged with the latched portion 7 and the hinge mechanism 8 is connected to the latched portion 6 and the latched portion 7. The hinge mechanism 8 may have a configuration in which the connecting portion is foldable in addition to the configuration having the rotating shaft in the connecting portion. The pulling mechanism 5 of the second aspect has a cross-sectional shape of “<” and makes it easy to pull the lens mounting portion 3 upward. The other structure of the pulling mechanism 5 is the same as that of the first aspect.
