Abstract

PURPOSE:To provide a container for contact lens, wherein the heat-sealed parts do not peel during a transport, the existence/absence of a contained contact lens can be confirmed from the outside through a transparent film, and the contact lens can be easily taken out. CONSTITUTION:A container main body 10 and lid 30 are openably connected. In the container main body 10, a storage part 12 in which a contact lens 40 is stored is formed. At an opening 13 of the storage part 12, an annular internal plug 20 is undetachably fitted. On the upper surface of the internal plug 20, a transparent film 24 is heat-sealed. On the outer periphery of a through hole 23, a thinner part 25 which can be cut is formed, and on the side end part, a protruding piece 27 is formed in such a manner that the protruding piece 27 may protrude more outside than the internal plug 20. By this method, a delicate control for the amount and strength of an adhesive, the temperature of the heat, or pressing force, etc., at the time of a heat-sealing becomes unnecessary, and the container becomes easier to open.

Is characterized in that a thin part that can be cut is formed on the outer periphery of the and the projecting piece projects from the thin part.

[0008]

According to the contact lens container of the present invention having the above-mentioned structure, the upper surface of the inner plug is cut by the thin portion by pulling up the projecting piece projecting from the thin portion, so that the transparent film portion is peeled off. It is not necessary to do so, and it is not necessary to control the amount and strength of the adhesive, the temperature of heat, the pressing force, etc. during heat sealing.

Further, at the time of taking out, the presence or absence of the contact lens in the container body can be confirmed by the transparent film heat-sealed on the upper surface of the inner plug.
