DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for inspecting a contact lens and a container.

[0002]

2. Description of the Related Art A contact lens manufactured by a contact lens maker based on a prescribed prescription is accommodated and held in simple containers 50 and 51 called blisters as shown in FIGS. . Simple containers (blisters) 50 and 51 are hemispherical lens housings 56.
Is formed by covering the opening side of the plastic container 55 with a sheet 57 made of aluminum foil or the like and heat-sealing the lens. FIG. 5 shows a type in which a plurality of lens housing portions 56, 56 are provided so as to be cuttable, and one lens housing portion 56 shown in FIG.
Is an individually wrapped type having

[0003] In the case of soft contact lenses, the use limit is short, so it is convenient for the user to purchase a plurality of lenses of the same type. A plurality of similar lenses are supplied (sold) at the same time. In such a case, the lens supplier checks (mainly, visual inspection) the lens housed in the simple container and hands it to the user. ) Is convenient. At the time of lens inspection, it is necessary to take out the lens from the simple container and transfer it to an appropriate inspection instrument. In addition, since these simple containers are disposable items that cannot be reused, a container for accommodating a lens after inspection must be prepared.

As described above, when inspecting a plurality of lenses of the same kind, it is necessary to transfer the lens from the simple container to the inspection instrument, and from the inspection instrument to another storage container after the inspection many times. . Such transfer of a plurality of lenses is extremely complicated and inefficient in work efficiency, and is not economically disadvantageous. In addition, repeated transfer may cause dirt or damage to the lens.

[0005] Furthermore, the most troublesome problem is the interchangeability of lenses. Even if a plurality of contact lenses of the same type are inspected as one batch, they are likely to be separated afterwards, and there is a high possibility of being mistaken. Needless to say, the prescription of the contact lens differs depending on the user, so that a mistake in the contact lens causes a great trouble and impairs the trust of the user.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and has a single inspection container and a single storage container after inspection, and simultaneously inspects a plurality of lenses of the same type at the same time. An object of the present invention is to provide a method and an apparatus for inspecting a contact lens, a container, and a container, which can avoid repeated transfer and prevent a trouble of mistaking a lens.

[0007]

【Example】

First, prior to the inspection method, the inspection tool of claim 2 shown in FIG. 1 will be described. The present invention comprises an inspection table 10, a container body 20, and a connection lid member 30. The inspection table 10 is configured such that a plurality of inspection recesses 12 having light transmission windows 13 for transmitting light from below are provided at regular intervals in a table body 11 made of, for example, a plastic molded product. The inspection concave portion 12 is generally formed by a concave curved surface as shown in the figure, and a circular light transmitting window 13 is opened in an inner bottom thereof. In the example of the drawing, three inspection recesses 12 are provided, but two or four or more inspection recesses 12 may be provided.
In the embodiment, the diameter of the opening edge 21 of the inspection recess 12 is 2
5 mm, and the interval between the inspection recesses 12 is 10 mm.

In FIG. 1, reference numeral 15 denotes a square check plate for displaying the left and right of the lens to be inspected and whether or not the inspection has been completed. Reference numeral 16 denotes an insertion groove portion of the check plate. In this example, the front and back surfaces of the check plate are color-coded red and blue, and "R" and "L" are displayed above and below each surface. For example, if a blue “R” is displayed toward the outside of the inspection table 10, it indicates the end of the inspection of the right lens, and if a red “L” is displayed, the inspection of the left lens is similarly performed. Is not completed.

The container body 20 is of a light-transmitting type placed in the inspection recess 12, and generally a transparent plastic container is advantageously used. The container body 20 of the embodiment is a molded product of polypropylene, and has a substantially hemispherical shape with an opening having a diameter of 24 mm and a depth of 16 mm.
