The lower end of the cutting blade 23 is located above the lower end of the inner cylinder portion 13. A plurality of cutting blades 23 may be formed. Further, a plurality of weakening portions 22 may be provided, and the weakening portions 22 may not be provided.

Next, the discharger 30 mounted on the replacement container 1 will be described.
As shown in FIG. 3, the discharger 30 is a pump-type discharger, and discharges a cylindrical mounting cap 31 for attaching the discharger 30 to the container body 2 and the contents contained in the container body 2. It includes a pump body 32.

The mounting cap 31 has a cylindrical mounting cylinder portion 41 and a cylindrical guide cylinder portion 42 that is connected above the mounting cylinder portion 41 and guides the vertical movement of the pressing head 52, which will be described later.
The mounting cylinder portion 41 has a larger diameter than the guide cylinder portion 42, and is screwed onto the inner peripheral surface of the mounting cylinder portion 41 with a male screw portion 3A formed at the mouth portion of the container body 2. A female screw portion 41A is formed. As a result, the mounting cylinder portion 41 is detachably screwed to the mouth portion 3 of the container body 2. The mounting cylinder portion 41 is not limited to a configuration in which it is screwed as long as it can be detachably mounted on the mouth portion of the container body 2.

The pump body 32 includes a cylinder 51 attached to the mounting cap 31 and a stem (not shown) whose lower portion is inserted into the cylinder 51 and is arranged so as to be vertically urged with respect to the cylinder 51 so as to be movable downward. , A piston (not shown) that is slidably fitted in the cylinder 51 in conjunction with the vertical movement of the stem, and is attached to the upper end of the stem and discharges the contents in the container body 2. It includes an eclipsed cylindrical pressing head 52 in which a discharge hole 52A is formed.

The suction pipe 53 can push the cutting member 5 downward around the hinge portion 21 and has at least a certain degree of rigidity. Further, at the upper end portion of the cylinder 51, an annular flange portion 51A is formed over the entire circumference in a plan view protruding outward in the radial direction. An annular packing 54 is arranged on the lower surface of the flange portion 51A in a plan view.

Next, a method of using the replacement container 1 having the above configuration will be described.
First, the lower end of the suction pipe 53 is vertically aligned with the recess 5B of the cutting member 5, and the discharger 30 is pushed downward with respect to the replacement container 1. By aligning the suction pipe 53 with the recess 5B, the suction pipe 53 is less likely to be displaced with respect to the cutting member 5 when the discharger 30 is pushed in. When the discharger 30 is pushed in, the weakened portion 22 is broken, the cutting member 5 rotates downward around the hinge portion 21, and the cutting edge 23 cuts the seal film 14. At this time, the user senses the feel and sound generated when the seal film 14 is broken. After that, as shown in FIG. 3, the seal film 14 is cut by the entire cutting member 5 to open the replacement container 1, and the suction pipe 53 passes through the opening formed in the seal film 14 by the cutting member 5 to form a container. Enter the main body 2. Then, as shown in FIG. 4, the mounting cylinder portion 41 is screwed onto the mouth portion 3 of the container body 2.

In this way, the discharger 30 is attached to the replacement container 1. When the container body 2 of the replacement container 1 is empty, the discharger 30 is removed from the mouth 3 of the container body 2, and the discharger 30 is placed in another replacement container 1 filled with the contents by the same procedure as described above. To wear. Since the cutting member 5 is pushed outward in the radial direction by the outer peripheral surface of the cylinder 51 at the time of mounting, it is suppressed that the seal film 14 cut by the cutting member 5 closes the communication hole 13A. Further, since the cutting member 5 is connected to the inner plug member 4 via the hinge portion 21, the cutting member 5 does not separate when the seal film 14 is broken, and the possibility that the cutting member 5 closes the communication hole 13A is reduced. There is.

As described above, according to the replacement container 1 according to the present embodiment, it is possible to easily determine whether or not the replacement container 1 has been opened by visually recognizing whether or not the seal film 14 has a broken portion, and the user himself / herself can determine whether or not the replacement container 1 has been opened. The act of breaking the 14 makes it easy for the user to recognize the freshness of the contained contents, for example, through the feel and sound generated at the time of breaking. Further, since the operation of breaking the seal film 14 and the operation of mounting the discharger 30 on the replacement container 1 can be continuously performed, the replacement work of the discharger 30 becomes easy.
Further, since the seal film 14 is attached to the lower end of the inner cylinder portion 13 of the inner plug member 4, the seal film 14 is unintentionally attached as compared with the case where the seal film 14 is attached to the upper end of the inner cylinder portion 13. It can be suppressed from being broken. Then, when the discharger 30 is attached, the sealing property between the upper surface of the annular top wall portion 11 and the packing 54 can be easily ensured.
Further, since the cutting member 5 is arranged above the communication hole 13A, it is possible to more reliably prevent the seal film 14 from being unintentionally broken.
Moreover, the number of parts can be reduced by integrally forming the cutting member 5 and the inner plug member 4.

At the lower end of the peripheral cylinder portion 114, a plurality of communication slits 114A extending in the vertical direction (three in the present embodiment) are formed at intervals in the circumferential direction. The communication slit 114A is formed between two cutting edges 115 adjacent to each other in the circumferential direction. It is sufficient that at least one cutting edge 115 and one communication slit 114A are formed.

Further, in the middle portion in the vertical direction of the peripheral cylinder portion 114, an annular protruding portion 114B protruding outward in the radial direction is formed over the entire circumference. By providing the annular protrusion 114B, it is suppressed that the broken seal film 14 sticks to the cutting member 112 so as to close the communication slit 114A.
Further, on the inner peripheral surface of the peripheral cylinder portion 114, a plurality of rib portions 114C extending from the lower end toward the intermediate portion in the vertical direction are formed at intervals in the circumferential direction (three in the present embodiment). ..
