摘要： The blister pack comprises a base portion and a cover layer. The base portion comprises a hollow chamber that contains a soft hydrophilic contact lens and a sterile aqueous preserving solution, and a substantially flat flange that extends right round the outside of the hollow chamber. The cover layer is releasably sealed to the flange in a sealing zone that extends right round the circumference of the hollow chamber. The flange comprises a grip region that extends from one side of the hollow chamber beyond the sealing zone and is covered by a corresponding grip region of the cover layer but is not sealed thereto. The hollow chamber comprises a dish-shaped main chamber and, adjoining the side of that main chamber, a secondary chamber in the shape of a channel tapering on all sides away from the main chamber, the main chamber making a smooth transition into the secondary chamber, and the main chamber and the secondary chamber together having a drop-shaped contour in the plane of the flange, the tip of which contour is directed towards the grip region of the flange. Provided in the grip region of the flange is an oval opening by means of which the overlying grip region of the cover layer can be lifted from the flange. A support element that is angled with respect to the plane of the flange is arranged in the grip region of the flange. An angled grip element or facilitating the handling of the blister pack is arranged at the edge of the flange on both sides of the hollow chamber. The base portion is so shaped that the blister packs can be nested in pairs with their undersides one inside the other, in each case the hollow chamber of one blister pack lying in the region of the grip region of the other blister pack. The blister pack is extremely handy, space-saving and stable, requires only an extremely small amount of preserving solution and enables the contact lens it contains to be removed especially easily.
摘要翻译：泡罩包装包括基部和覆盖层。底座部分包括一个包含柔软的亲水性隐形眼镜和无菌水性保存液的中空腔，以及在中空腔外侧向外延伸的基本平坦的凸缘。覆盖层在密封区域中可释放地密封到凸缘上，密封区域在中空室的圆周的右侧延伸。凸缘包括从中空室的一侧延伸超过密封区并被覆盖层的相应夹持区域覆盖但不被密封的手柄区域。中空室包括碟形主室，并且邻近该主室的一侧，具有在远离主室的所有侧面上渐缩的通道形式的第二室，主室平滑地过渡到次室，并且主室和副室一起在凸缘的平面中具有液滴形轮廓，其顶端的轮廓指向凸缘的把手区域。在凸缘的把手区域中设置有椭圆形的开口，通过该椭圆形开口可以覆盖层的覆盖夹持区域从凸缘提升。相对于凸缘的平面成角度的支撑元件布置在凸缘的把手区域中。倾斜的夹紧元件或便于处理泡罩包装被布置在中空室两侧的凸缘的边缘处。底部部分是这样成形的，使得泡罩包装件可以与它们的下侧成对嵌套，一个在另一个内部，在每种情况下，一个泡罩包装袋的中空室位于另一个泡罩包装的抓握区域的区域中。泡罩包装非常方便，节省空间并且稳定，只需要极少量的保存溶液，并且使其包含的隐形眼镜被特别容易地去除。
