Further, an annular inclined wall 5a3 connected to the lower end of the inner cylindrical portion 5a2 is integrally provided inside the inner tubular portion 5a2. The lower end portion of the inclined wall 5a3 is integrally connected to the inner cylindrical portion 5a2 via the flat wall 5a4. A pouring nozzle 5c formed with an internal passage R2 leading to the container 4 is integrally provided to the inclined wall 5a3. The injection nozzle 5c forms an annular recess S2 between the tubular portion 5b and the inner tubular portion 5a2.

As shown in FIG. 25(b), the injection nozzle 5c is formed with a slit-shaped injection port A obliquely from the upper end (front end) 5e in the direction of the central axis O2.

When the refill cap 2 refills the contents of the refill container 1 into the container 4, as shown by the two-dot chain line in Fig. 26, the refill container 1 is placed upside down. The injection nozzle 5c of the container 4 is inserted into the inside of the cylindrical portion 2b, and the projection 2d provided in the cylindrical portion 2b is guided to the injection port A formed in the injection nozzle 5c as shown in Fig. 27, thereby It can move in the direction of the central axis O1. Thereby, the refill container 1 can be fitted to the container 4 in a state of being aligned with the circumferential direction.

Thus, if the protrusion 2d is provided in the cylindrical portion 2b, it can be formed in the injection spray The injection port A of the nozzle 5c is guided so that the refill container 1 is fitted in a state of being aligned with the center axis O2 of the container 4 at an appropriate position in the circumferential direction. In particular, when a plurality of projections 2d are formed, the projections 2d can be easily brought into contact with the edge portion of the discharge nozzle 5c forming the injection port A, and therefore it is preferable as the guide. That is, the space between the plurality of protrusions 2d can be made into an elastic deformation space, and the protrusion 2d which contacts the edge part of the injection nozzle 5c can be bent in this space. Therefore, a stable guide can be achieved.

Further, since the chamfered portion 2e is provided at the end side corner portion of the projection 2d, when the injection nozzle 5c is inserted into the inside of the cylindrical portion 2b, the upper end 5e of the injection nozzle 5c is in contact with the front end angle of the projection 2d. In the portion, the alignment is facilitated by the chamfered portion 2e. As shown in Fig. 27, the projection 2d can be disposed at the injection port A formed in the injection nozzle 5c, and can be formed on the projection 2d (front end side). The wall portion of the injection nozzle 5c is disposed between the inside of the tubular portion 2b.

Thereby, the upper end 5e of the injection nozzle 5c ejects the peripheral portion of the sealing member 3 (the partition wall 3a), and the sealing member 3 can be removed with a small force.

As described above, when the chamfered portion 2e is provided at the end side corner portion of the projection 2d, the chamfered portion 2e can be guided, and the projection 2d can be disposed at the injection port A formed in the injection nozzle 5c, and the injection nozzle can be placed. 5c is easily inserted between the protrusion 2d and the inner side of the barrel portion 2b.

Further, on the inner side of the tubular portion 2b, as shown in FIG. 24 and the like, the protruding portion 2f having the inclined surface 2f1 is integrally provided at a position sandwiching both sides of the folded portion 2c. Therefore, when the injection nozzle 5c is inserted into the inside of the tubular portion 2b, even if the upper end 5e of the injection nozzle 5c contacts the inclined surface 2f1, the alignment with the inclined surface 2f1 becomes easy, as shown in the figure. 27 can be The projection 2d is disposed at the injection port A formed in the discharge nozzle 5c, and the wall portion of the injection nozzle 5c is disposed between the projection 2d and the inner side of the tubular portion 2b.

By providing the protruding portion 2f having the inclined surface 2f1 on the inner side of the cylindrical portion 2b, the projection 2d can be more easily disposed on the injection port A formed in the discharge nozzle 5c, and the injection nozzle 5c can be easily disposed. Inserted between the projection 2d and the inner side of the barrel portion 2b. Further, by setting the protruding portion 2f to a size that slides or is close to the outer surface of the dispensing nozzle 5c, it is possible to suppress the content liquid flowing out from the side surface of the injection port A.

Further, in the state of being aligned as described above, the folded portion 2c formed inside the cylindrical portion 2b faces the injection port A of the discharge nozzle, and the projection 2d is provided in the folded portion 2c. When the injection nozzle 5c is inserted into the inside of the tubular portion 2b, when the upper end 5e of the nozzle 5c is injected or the edge portion forming the injection port A is in contact with the folded portion 2c, the alignment by the folded portion 2c becomes As shown in Fig. 27, the projection 2d can be disposed in the injection port A formed in the injection nozzle 5c, and the wall portion of the injection nozzle 5c can be disposed between the projection 2d and the inner side of the tubular portion 2b.

In this manner, even if the projection 2d is provided via the folded portion 2c, the folded portion 2c can be guided, and the projection 2d can be disposed at the injection port A formed in the discharge nozzle 5c, and the injection nozzle 5c can be easily inserted into the projection. 2d is between the inside of the barrel portion 2b.

Further, since the folded portion 2c is provided in the tubular portion 2b, as shown in Fig. 28, when the sealing member 3 is press-fitted, as shown in Fig. 28, the folded portion 2c covers the injection port at least partially in the radial direction. A, so that it is possible to ensure that at least a part of the remaining injection outlet A is used as an external air inlet. Refilling of the liquid. Thereby, even if the refilling container 1 is inverted, the content liquid can be prevented from being ejected from the injection nozzle 5c through the injection port A, and the content liquid can be refilled.

Further, in consideration of the case where the folded portion 2c is not provided, the content liquid flowing out from the tubular portion 2b flows down the outer surface of the dispensing nozzle 5c, whereby the entire injection port A is blocked. Air replacement is not possible, causing the contents to overflow.

Further, the projection 2d may be configured to be guided in the circumferentially narrow opening A2. In this case, the folded portion 2c blocks the narrow gap A2 in the circumferential direction. Further, the injection port A may be formed as a slit having the same width in the circumferential direction by forming the circumferential width of the wide-width opening A1 and the circumferential narrow-width opening A2 to be equal. Further, on the narrow-width port A2 side in the circumferential direction of the injection nozzle 5c, protrusions 5h are provided at positions sandwiching the circumferential narrow-width port A2. As shown in FIG. 28, the ridge 5h functions as a stopper by contacting the folded portion 2c of the refill cap 2.

However, at the time of refilling, as described above, if the upper end 5e of the nozzle 5c is ejected to eject the peripheral portion of the sealing member 3, the sealing member 3 can be removed with a small force. Therefore, according to the present invention, various forms can be employed for the sealing member 3.

Fig. 30 is a cross-sectional view of a principal part showing a state in which the refill cap 2 having the other sealing member 31 according to the present invention is attached to the refill container 1. The sealing member 31 is as shown in Figs. 31(a) and 31(b), and instead of the flat partition wall 3a as described above, the partition wall is used as shown in Fig. 31(a), having a center axis O1. Reduce the diameter of the slope upwards and radially inward 3d, and as shown in FIG. 31(b), is a conical shape which is tapered toward the tip end of the apex 3e passing through the center axis O1, and an annular flat surface 3r connected to the inclined surface 3d is formed around the outer edge of the conical shape. .

In this case, as shown in FIG. 32(a), when the refilling nozzle 1 is inserted into the inside of the tubular portion 2b in a state where the refilling container 1 is inverted, as shown in FIG. 32(b), The upper end 5e of the injection nozzle 5c is guided by the inclined surface 3d, and moves to the outer peripheral portion (the annular flat surface 3r) of the seal member 31. Thereby, the upper end 5e of the injection nozzle 5c is moved toward a portion closer to the outer peripheral portion (the annular flat surface 3r) of the sealing member 31, and the sealing member 31 can be effectively removed with a small force.

Furthermore, the flat surface 3r may not be provided.

Such a function can also be realized by using a sealing member having partition walls as shown in Fig. 33 (a), Fig. 33 (b) or Figs. 34 (a) and 34 (b).

33(a) and 33(b) are still other sealing members 32 according to the present invention. The sealing member 32 is a partition wall having two inclined faces 3f which are inclined radially inward as the center axis O1 is upward as shown in Fig. 33 (a), and is oriented horizontally as shown in Fig. 33 (b). The ridge line of the center axis O1 has a 3L front end tapered mountain shape (gabled roof shape), and an annular flat surface connected to the inclined surface 3f is formed around the outer edge of the mountain shape. Face 3r. In this case, the upper end 5e of the injection nozzle 5c is also guided to the portion closer to the outer peripheral portion (the annular flat surface 3r) of the sealing member 32 by the inclined surface 3f, and can be effectively operated with a small force. The sealing member 32 is removed. Further, according to the present invention, the partition wall of the sealing member may be constituted by only one inclined surface 3f.

Figures 34(a) and 34(b) show still another sealing member 33 according to the present invention. The sealing member 33 is a partition wall having a slope 3d which is reduced in diameter toward the inside in the radial direction as shown by the center axis O1 as shown in Fig. 34 (a), and is oriented toward the crossing as shown in Fig. 34 (b). A truncated cone shape having a flat upper end surface 3p and a tapered front end of the central axis O1 is formed, and an annular flat surface 3r connected to the inclined surface 3d is formed around the outer edge of the truncated cone shape. In this case, the upper end 5e of the injection nozzle 5c is also guided by the inclined surface 3d toward the portion closer to the outer peripheral portion (the annular flat surface 3r) of the sealing member 33, and can be effectively used with a small force. The sealing member 33 is removed.

That is, in the present invention, as long as the shape which is tapered toward the upper end is used as the partition wall of the sealing member, the sealing member 3 can be effectively removed with a small force.

The above description of one embodiment of the present invention is not limited thereto, and various modifications can be made without departing from the scope of the invention. For example, the sealing member 3 may use a sealing member that seals the injection port of the mouth portion 1a instead of the fitting member. In this case, the sealing member is opened by breaking the upper end 5e of the nozzle 5c. According to the present invention, the discharge nozzle 5c on the side of the container 4 can be fitted from the outside as long as the cylindrical portion 2b on the side of the container 1 for refilling, and the upper end of the injection nozzle 5c from the injection port A along the central axis For the O2 direction former, various types can be employed. Further, in the present embodiment, the central axes O1 and O2 coincide with the container axis of the refill container 1 and the container axis of the container 4, but may be configured to be eccentric with respect to the container axis.

Further, in the present invention, as shown in the modification shown in Fig. 29, the notch portion 2s is provided in the cylindrical portion 2b, and the projection 2d can be visually recognized from the notch portion 2s. By the way, the alignment becomes easy. In this case, the notch portion 2s is preferably disposed at a position opposed to the front end of the projection 2d.
