However, in the contact lens package of Patent Document 1 and the contact lens package of the second embodiment of Patent Document 2, since the wall portions (foot portions) are engaged with each other by friction, a pair of packages are unitized into one unit. There is a risk that they will deviate from each other. That is, in the contact lens package of Patent Document 1, the main wall and the sub-wall are arranged on a parallel plane with a space therebetween, so that the pair of packages are separated from each other in the longitudinal direction in the lateral direction. In the second embodiment of Patent Document 2, there is a possibility that the legs located on the outside are adjacent to each other in the pair of packages unitized into one unit (for example, In FIG. 9 of Patent Document 2, the foot portion 103 and the foot portions 105 ′ and 107 ′ on both sides thereof are adjacent to each other), and a space is provided between the adjacent outer foot portions. One package may shift in the rotational direction with respect to the other package.

Further, in the contact lens package of the first embodiment of Patent Document 2, since the grip is engaged with the outside of the skirt, the grip is likely to come into contact with the outside, and the unitization may be easily released in an unexpected state. There is. For example, when a unitized package is taken out from a state in which it is stored in a pocket, there is a possibility that the grip is caught by the edge of the pocket and the engagement is disengaged. Also, in the contact lens package of the second embodiment of Patent Document 2, the ends 122, 122 ', 123, 123' of the long legs 105, 105 ', 107, 107' are frictionally caused by the friction on the opposite side of the package skirt. Since it engages with the outside of 116, 116 ', a long leg part is easy to contact the outside, and there is a possibility that unitization may be easily canceled in an unexpected state.

Therefore, the present invention does not cause the packaging containers to be displaced from each other from the state in which the pair of packaging containers are unitized, and the unitizing member contacts the outside in the unitized state.

The protruding portion 64 of the mating portion 60 is fitted into the hole 66 of the other engaging portion 60, and the protruding portion 64 of the other engaging portion 60 is fitted to the hole 66 of the one engaging portion 60. Since the engaging portions 60 are engaged with each other, there is no possibility that the packaging containers are shifted from each other from the state in which the pair of packaging containers are unitized.

Further, in the packaging container 10, the engaging

portions

50, 60 are provided inside the wall portion 40, and the engaging portion can be engaged even when the pair of packaging containers 10 are integrated by the engaging portion 50 and the engaging portion 60. Since 50 and 60 are provided inside the wall portion 40, the unitization is not easily released when a member for unitization (that is, the engaging portions 50 and 60) contacts the outside. . In particular, since the engaging

portions

50 and 60 are covered with the pair of wall portions 40 and are not visible from the outside, the members for unitization (that is, the engaging portions 50 and 60) come into contact with the outside. Unitization is not easily released.

The length of the engaging portion 50 in the height direction is formed shorter than the length of the right wall portion 44 in the height direction, and the length of the engaging portion 60 in the height direction is the height of the left wall portion 46. Since it is formed shorter than the length in the vertical direction, a member for unitizing the pair of packaging containers 10 (that is, the engaging portions 50 and 60) becomes an obstacle when the packaging container 10 is used as a single unit. There is no. Furthermore, most of the engaging portions 50 are configured to be hidden by the right wall portion 44 in the right side view of the packaging container 10 (see FIG. 9). Most of the components are hidden behind the left wall portion 46 (see FIG. 10), so that the members (that is, the engaging portions 50 and 60) for unitizing the pair of packaging containers 10 also serve as the packaging container 10. When using as a single unit, it will not get in the way.

That is, the secondary wall in the contact lens package of Patent Document 1 is formed long in the height direction in order to mesh with the main wall by friction (as shown in FIGS. 4 and 5 of Patent Document 1). The length of is formed in the same length as the height direction of the main wall), and when using one contact lens package after releasing the unit, there is a high possibility that the secondary wall will come into contact with the other, There is a problem that the auxiliary wall becomes an obstacle. Similarly, the foot part of the first aspect and the foot part of the second aspect of Patent Document 2 are formed so as to protrude from the periphery of the support. The foot is formed long to engage the skirt of the other package, and the foot of the second embodiment is formed long enough to reach the skirt of the other package to engage the foot of the other package So When using one contact lens package to release the reduction is a high possibility that the foot is in contact with the other, there is a problem that the foot becomes a hindrance. That is, in the packages of Patent Document 1 and Patent Document 2, there is a problem that a member for unitizing a pair of packaging containers becomes an obstacle when the package is used as a single unit. In the packaging container 10, the members for unitizing the pair of packaging containers 10 (that is, the engaging portions 50, 60) do not get in the way when the packaging container 10 is used as a single unit.

In the above description, in the engaging portion 50 and the engaging portion 60, the protruding portion 54 is provided on the back side of the hole portion 56, and the protruding portion 64 is provided on the front side of the hole portion 66. However, the protruding portion 54 is provided on the front side (one side of the front side and the back side) of the hole portion 56, and the protruding portion 64 is on the back side (front side and back side of the hole portion 66). It is good also as a structure provided in the other side). That is, in this case, the projecting portion 54 is provided on the first side (that is, the front side) which is one of the front side and the back side, and the hole portion 56 is the other of the front side and the back side. Provided on the second side (that is, the back side), the projecting portion 64 is provided on the second side (that is, the back side), and the hole portion 56 is provided on the first side (that is, the front side). Provided.
