As shown in FIG. 1, an annular engaging recess 7a corresponding to the engaging convex portion 5e of the lid 5 is provided on the inner peripheral surface of the overcap 7. As a result, the overcap 7 is detachably held with respect to the lid 5.

As shown in FIG. 1, the container assembly 100 composed of such members can cover the discharger 2 with the overcap 7, and thus prevents dust and the like from adhering to the discharge head 2b during storage. In addition, it is possible to prevent a problem in which the discharge head 2b is inadvertently pushed in and the contents are unintentionally discharged. Here, as shown in FIG. 2, since the engaged portion 6c of the lock member 6 is caught in the recess 4c, the lid body 5 is held so as not to come out from the container body 4.

Then, when the overcap 7 is removed and the discharge head 2b is pushed in, the pump mechanism provided in the discharger 2 is driven to discharge the contents from the discharge head 2b.

Further, according to the container assembly 100, the container body 4 and the lid 5 have an elliptical cross section and are different in shape from the conventional ones, which are mostly round, so that the container body 4 and the lid 5 are novel. Can be done. Further, since the operation unit 6e is exposed from the window hole 5d, for example, if the operation unit 6e is decorated, the appearance can be improved.

When the contents are used up and the refill container 1 is replaced, the operation unit 6e is pressed inward in the radial direction as shown in FIG. 5A. As a result, as shown in FIG. 5B, the annular wall 6a bends inward in the radial direction, so that the recess 4c and the engaged portion 6c are released from being caught, and the lid 5 is removed from the container body 4. be able to. Since the operation unit 6e is located above the annular wall 6a, if the operation unit 6e is pushed in so as to be tilted in the vertical direction, the annular wall 6a may be bent so as to be twisted. In the embodiment, the upper extending portion 6d connected to the operating portion 6e slides on the upper surface of the flange 5c, and the lower extending portion 6b slides on the lower surface of the flange 5c, so that the operating portion 6e is pushed straight in. The annular wall 6a does not bend so as to twist. Further, since the operation unit 6e is provided on the short axis side of the annular wall 6a, which is more flexible than the long axis side, the lid 5 can be removed from the container body 4 without pressing with such a large force. Here, since the outer peripheral surface of the operation unit 6e does not protrude radially outward from the outer peripheral surface of the lid peripheral wall 5a, the problem that the operation unit 6e is inadvertently pushed in is effectively prevented. Further, the annular wall 6a is in contact with or close to the convex portion 1e on the short axis side in the cross section, and the annular wall 6a is radially inward to the extent that the pressing force on the operating portion 6e is not excessively required. It creates resistance when it bends. Therefore, the problem that the operation unit 6e is unintentionally pushed in is more effectively prevented.

After removing the lid 5 from the container body 4, the used refill container 1 is removed from the container body 4, and the discharger 2 removed from the refill container 1 is attached to a new refill container 1. Then, by attaching the new refill container 1 to the container body 4 and attaching the lid 5 to the container body 4, the contents can be discharged again.
