Description

The present invention relates to a spray container that sprays liquid contents from a spray outlet.

There are known spray containers that spray the liquid contained in the container from a nozzle. For example, Patent Document 1 shows a spray container that includes a container that stores the liquid, a sprayer with an upwardly biased stem, and a head that is attached to the stem, and is configured so that the sprayer is driven by pushing down on the head, causing the liquid to be sprayed from the nozzle of the head. Such spray containers generally have a cylindrical container shape, as shown in Patent Document 1.

JP 2002-11394 A

There is a certain demand for such spray containers that can be carried around and used on the go. For this reason, consideration is being given to making the containers thinner and flatter so that they do not get in the way when carried around. In addition, consideration is being given to providing an injection port for refilling the contents so that they can be reused even after the contents have been used up.

However, flat containers have a problem in that the size of the injection port must be small to accommodate their thin thickness, making it difficult to fill them with the liquid.

In view of these points, the present invention aims to provide a spray container that is thin, highly portable, and easy to fill with liquid.

The present invention provides a spray container comprising a container having a storage space for storing liquid content, a sprayer having an upwardly biased stem, and a spray head having a spray outlet and connected to the stem, the sprayer being driven by pushing down the spray head to spray the liquid content of the storage space from the spray outlet,
The container has a container body having a flat shape with a width greater than a thickness and including the storage space, and an adapter detachably held by the container body,
The container body has an injection tube having an injection port at a tip thereof that communicates with the storage space and an outer shape that fits within the thickness of the container body, and a holding portion that holds the adapter,
the adapter has a one end opening and an other end opening at both ends, and has an outer circumferential wall that surrounds the casting cylinder when the one end opening is inserted into the casting cylinder, and the other end opening is located outside the tip of the casting cylinder ;
The outer peripheral wall is a jetting container that has a flat shape with a width greater than a thickness and is elastically deformable in a direction in which the thickness increases .
The present invention also provides a spray container comprising a container having a storage space for storing liquid content, a sprayer having an upwardly biased stem, and a spray head having a spray outlet and connected to the stem, the sprayer being driven by pushing down the spray head to spray the liquid content of the storage space from the spray outlet,
The container has a container body having a flat shape with a width greater than a thickness and including the storage space, and an adapter detachably held by the container body,
The container body has an injection tube having an injection port at a tip thereof that communicates with the storage space and an outer shape that fits within the thickness of the container body, and a holding portion that holds the adapter,
the adapter has a one end opening and an other end opening at both ends, and has an outer circumferential wall that surrounds the casting cylinder when the one end opening is inserted into the casting cylinder, and the other end opening is located outside the tip of the casting cylinder;
the container body has a casting cylinder side holding part that fits into the one-end side opening in a state where the one-end side opening is inserted into the casting cylinder,
At least one of the one end opening and the casting cylinder side holding part is also a jet container having a groove part that provides a gap between the one end opening and the casting cylinder side holding part.
The present invention also provides a spray container comprising a container having a storage space for storing liquid contents, a sprayer having an upwardly biased stem, and a spray head having a spray outlet and connected to the stem, the sprayer being driven by pushing down the spray head to spray the liquid contents of the storage space from the spray outlet,
The container has a container body having a flat shape with a width greater than a thickness and including the storage space, and an adapter detachably held by the container body,
The container body has an injection tube having an injection port at a tip thereof that communicates with the storage space and an outer shape that fits within the thickness of the container body, and a holding portion that holds the adapter,
the adapter has a one end opening and an other end opening at both ends, and has an outer circumferential wall that surrounds the casting cylinder when the one end opening is inserted into the casting cylinder, and the other end opening is located outside the tip of the casting cylinder;
The container body serves as a spray container, holding the sprayer in the center in the width direction, having the injection tube at one end in the width direction, and having the holding portion at the other end in the width direction.

It is preferable that the adapter has a plurality of ribs on the inside of the outer wall that are arranged point symmetrically with respect to the opening at one end.

It is preferable that the rib has an inclined portion that approaches the center of the one-end opening from the other-end opening toward the one-end opening.

It is preferable that, with the one-end opening of the adapter inserted into the injection tube, a nozzle provided on the pressing head of the discharge container can be inserted from the other-end opening.

The spray container of the present invention is highly portable because the container body is flat and thin. In addition, because this spray container has the adapter described above, when the opening at one end of the adapter is inserted into the injection tube used to fill the liquid content provided in the container body, the injection tube is surrounded by an outer wall, and the opening at the other end of the adapter is positioned outside the tip of the injection tube. Therefore, by inserting a nozzle or the like from which the liquid content is to be filled into the opening at the other end of the adapter, the injection port of the injection tube can be aligned with the nozzle or the like, so that the liquid content can be easily filled even if the container body is flat.

One embodiment of a spray container according to the present invention will be described below with reference to the drawings. In the following description, "top" and "bottom" refer to the positional relationship when the spray container is held upright as shown in FIG. 1. Furthermore, "front" refers to the side where the spray nozzle, which will be described later, is located, and "rear" refers to the opposite side. Furthermore, "left" and "right" refer to the left and right directions when looking at the spray container from front to rear.

First, a first embodiment of the spray container according to the present invention will be described with reference to Figs. 1 to 4. The spray container 1A of this embodiment includes a container 2, a sprayer 3, and a spray head 4. The container 2 includes a container body 5 (comprised of a lower container 6, an upper container 7, and a holder 8), a cap 9, and an adapter 10. The sprayer 3 includes a cylinder 11, a pipe 12, a stem 13, and the like. The spray head 4 includes a head body 14, a nozzle tip 15, and an operating body 16. These members are basically made of synthetic resin, but the material is not limited to this. For example, the upper container 7 may be made of glass. Various methods for forming the members can be selected. The upper container 7 of this embodiment is made of synthetic resin formed by injection molding, but the manufacturing method is not limited to this, and it may be formed by blow molding, for example.

The lower container 6 is shaped like a cylinder with a bottom, centered on the axis A1 shown in FIG. 1, and has a stepped portion 6a at its upper end, with the radially outer side being made thinner.

The upper container 7 is shaped like a lidded cylinder, and its lower end is liquid-tightly joined to the stepped portion 6a, for example, by ultrasonic welding. Various methods can be used to join the lower end of the upper container 7 to the stepped portion 6a, and adhesives may be used, or the containers may be joined by fitting only. As shown in the figure, the joined lower container 6 and upper container 7 have a flat shape (a thin rectangular parallelepiped shape) with a width (length in the left-right direction) greater than its thickness (length in the front-to-back direction). A storage space S is formed inside the joined lower container 6 and upper container 7 to store the liquid contents.

As shown in FIG. 1, the upper container 7 is shaped so that the central portion in front view is concave downwards. The configuration of this shape will be described in detail below. The upper container 7 has a lower top wall portion 7a extending horizontally in the widthwise central portion. An opening 7b is provided in the central portion of the lower top wall portion 7a through which the cylinder 11 can protrude upwards. A vertical wall portion 7c extending upwards is provided on the left-right outer edge of the lower top wall portion 7a, and an engagement protrusion 7d protruding toward the axis A1 is provided in the vertical middle portion of the vertical wall portion 7c.

As shown in FIG. 1, the vertical wall portions 7c located on the right side and the left side have different vertical lengths (the vertical wall portion 7c located on the right side is longer in the vertical direction than the vertical wall portion 7c located on the left side).

The upper end of the vertical wall 7c located on the right side is connected to the right side ceiling wall 7e. The right side ceiling wall 7e is provided with a cylindrical injection tube 7f extending upward. An injection port 7g that leads to the storage space S is opened at the tip of the injection tube 7f, and when the content liquid stored in the storage space S becomes low, the content liquid can be added through the injection port 7g. The outer peripheral surface of the injection tube 7f is provided with a container side threaded portion 7h that has a male thread shape. As shown in FIG. 4(d), the container side threaded portion 7h has a notch portion 7j that cuts it in the vertical direction. At the lower end of the injection tube 7f, a root portion 7k that has a larger diameter than the injection tube 7f is provided. The root portion 7k holds the adapter 10 into which the injection tube 7f is inserted, as described later, and corresponds to the "injection tube side holding portion" in this specification. The outer peripheral surface of the root portion 7k is provided with a groove portion 7m located directly below the notch portion 7j, as shown in FIG. 4(d).

The upper end of the vertical wall 7c located on the left side is connected to the left lower wall 7n, which is rectangular and tubular. The left top wall 7p is connected to the upper end of the left bottom wall 7n, and the left top wall 7q, which is cylindrical and has a closed top end, is connected to the upper surface of the left top wall 7p. The left top wall 7p has a bulge 7r in the center in the front-to-rear direction as shown in FIG. 2(a). The bulge 7r is formed by protruding the lower end of the left top wall 7q radially outward as shown in FIG. 1. The left bottom wall 7n, the left top wall 7p, the left top wall 7q, and the bulge 7r are the parts that correspond to the "retaining portion" in this specification.

As shown in FIG. 1, the holder 8 has a holder top wall 8a extending horizontally. An opening 8b is provided in the center of the holder top wall 8a, through which the stem 13 can protrude upward. An inner engagement portion 8c and an outer engagement portion 8d that engage with the cylinder 11 are provided on the underside of the holder top wall 8a. A holder side wall 8e extending vertically is provided on the left-right outer edge of the holder top wall 8a. A portion that protrudes away from the axis A1 and engages with the engagement protrusion 7d is provided in the vertical middle portion of the holder side wall 8e, whereby the holder 8 is held in the upper container 7. A holder top wall 8f extending horizontally is provided on the upper end of the holder side wall 8e.

As shown in Figs. 1 and 2, the cap 9 can be attached to the right side of the upper container 7, and when attached to the upper container 7, as shown in the figures, it is shaped to match the outer surface of the upper container 7. The cap 9 has a rectangular cylindrical cap peripheral wall 9a whose width (length in the left-right direction) is greater than its thickness (length in the front-rear direction). The upper end of the cap peripheral wall 9a is provided with a cap top wall 9b that slopes inward as it goes upward and then extends horizontally. A cylindrical wall 9c is provided on the lower surface of the cap peripheral wall 9a, surrounding the injection tube 7f, and the inner peripheral surface of the cylindrical wall 9c is provided with a male-threaded cap side threaded portion 9d that is shaped to correspond to the container side threaded portion 7h. The cap 9 is attached to the upper container 7 by screwing the cap side threaded portion 9d into the container side threaded portion 7h. In addition, a seal wall 9e is provided on the inside of the cylindrical wall 9c, which is inserted into the injection tube 7f and abuts against it in a liquid-tight manner when the cap 9 is attached to the upper container 7.

The adapter 10 can be attached to the left side of the upper container 7 as shown in Figs. 1 and 2, and when attached to the upper container 7 as shown in the figures, it is shaped to match the outer surface of the upper container 7. The adapter 10 has an outer peripheral wall 10a that is rectangular and cylindrical, with a width (length in the left-right direction) greater than a thickness (length in the front-rear direction) and one size larger than the left lower wall portion 7n. The upper end of the outer peripheral wall 10a is provided with an adapter top wall portion 10b that slopes inward as it goes upward and then extends horizontally, and a circular opening (one end opening 10c) is provided in the center of the adapter top wall portion 10b. The lower end of the outer peripheral wall 10a is provided with a rectangular opening (other end opening 10d). The vertical length of the adapter 10 (the vertical length from the one end opening 10c to the other end opening 10d) is longer than the vertical length from the tip of the injection tube 7f to the base portion 7k.

A number of ribs 10e are provided on the inside of the outer peripheral wall 10a. As shown in FIG. 2(a), the ribs 10e of this embodiment extend from the one end opening 10c toward the corners of the outer peripheral wall 10a in a plan view, and a total of four ribs 10e are arranged point symmetrically with respect to the one end opening 10c. In addition, as shown in FIG. 1, the ribs 10e of this embodiment have an inclined portion 10f at their lower end that approaches the center of the outer peripheral wall 10a as it moves from the bottom to the top.

In this embodiment, the outer peripheral wall 10a is thin-walled and can be elastically deformed in a direction that increases its thickness (length in the front-to-rear direction), as shown by the solid line in FIG. 4(a).

When the other end opening 10d of the adapter 10 of this embodiment is inserted into the left lower wall portion 7n and the one end opening 10c is inserted into the left upper wall portion 7q as shown in FIG. 1, the outer peripheral wall 10a removably fits into the left lower wall portion 7n. Here, since the outer peripheral wall 10a and the left lower wall portion 7n are both rectangular in plan view, the adapter 10 is prevented from rotating relative to the upper container 7. Furthermore, when the adapter 10 is held in the upper container 7, the bulge portion 7r of the upper container 7 fits between the two ribs 10e located at the front and rear as shown in FIG. 2(a), so the adapter 10 is more reliably prevented from rotating.

The cylinder 11 is roughly cylindrical in shape, and contains a check valve, piston, spring, etc. (not shown). A pipe 12 is attached to the bottom of the cylinder 11. A stem 13 is provided at the top of the cylinder 11. The stem 13 is biased upward by a spring disposed in the cylinder 11.

When the stem 13 of the ejector 3, which is composed of the cylinder 11 and the like, is pressed down, the piston disposed in the cylinder 11 also moves downward, pressurizing the interior of the cylinder 11, and the liquid contained in the cylinder 11 is sent through the stem 13 to the downstream portion connected to the stem 13. When the pressure on the stem 13 is released, the piston moves upward due to the spring disposed in the cylinder 11, thereby reducing the pressure inside the cylinder 11, and the liquid contained in the storage space S can be introduced into the cylinder 11 through the pipe 12. The ejector 3 is held in the upper container 7 with the stem 13 protruding from the opening 8b described above.

The head body 14 has a flat shape with a width (length in the left-right direction) greater than its thickness (length in the front-to-back direction).

The detailed shape of the head body 14 will now be described with reference to Figs. 1 and 2. Fig. 2(b) shows the cross-sectional shape of the head body 14 at the center in the width direction. In this area, the head body 14 has a front wall 14a and a rear wall 14b that extend vertically. A horizontal wall 14c that extends horizontally is provided at the upper end of the rear wall 14b.

Figure 1 shows the cross-sectional shape of the head body 14 at the center in the thickness direction. In this area, the head body 14 has a pair of lower side walls 14d that extend vertically, and a pair of upper side walls 14e that extend vertically and are located closer to the axis A1 than the lower side walls 14d. A cylindrical shaft portion 14f that extends horizontally is provided on the outer surface of the upper side walls 14e.

A cylindrical internal tubular wall 14g is provided inside the head body 14. The internal tubular wall 14g is fitted and held on the outer peripheral surface of the stem 13. Furthermore, an internal passage 14h that connects to the internal tubular wall 14g is provided inside the head body 14. The internal passage 14h opens at the front wall 14a, and a nozzle tip 15 is attached to this opening. The nozzle tip 15 has an ejection port 15a that connects to the internal passage 14h.

The control body 16, like the head body 14, has a flat shape with a width (length in the left-right direction) greater than its thickness (length in the front-to-back direction).

As shown in FIG. 2(b), the operating body 16 has an upper wall 16a located at the top and extending horizontally, a front wall 16b connected to the front end of the upper wall 16a and inclined away from the axis A1 as it extends downward, and a rear wall 16c connected to the rear end of the upper wall 16a and inclined away from the axis A1 as it extends downward. The lower part of the front wall 16b extends to cover the front surface of the nozzle tip 15. Here, the part of the front wall 16b that covers the front surface of the nozzle tip 15 is referred to as a cover part 16d.

As shown in FIG. 1, the operating body 16 also has a pair of partition walls 16e located on the outer side in the width direction of the upper side wall 14e. The partition walls 16e have a circular hole (bearing portion 16f) into which the shaft portion 14f is inserted.

Furthermore, as shown in FIG. 1, the operating body 16 has a pair of lower walls 16g located on the outer side in the width direction of the partition wall 16e. As shown in the figure, the lower walls 16g are located directly above the holder top wall portion 8f.

The control body 16 thus configured can rotate relative to the head body 14 by the shaft portion 14f and the bearing portion 16f, and can be displaced from a position in which the upper wall 16a is positioned upward (upright position) to a position in which the upper wall 16a is rotated 90 degrees backward (inclined position) as shown in FIG. 2(b).

As shown in FIG. 1, the spray container 1A of this embodiment is constructed from such members, and the sprayer 3 is held in the center of the width of the container body 5. In addition, a cap 9 and an adapter 10 are held on either side of the sprayer 3. By arranging the sprayer 3, cap 9, and adapter 10 side-by-side in this manner, the thickness of the container body 5 can be made thin. In addition, since the adapter 10 can be carried together with the container body 5, the filling operation of the content liquid, which will be described later, can be easily performed on the go.

In addition, as shown in FIG. 2(b), when the operating body 16 is displaced to the upright position, the operating body 16 is contained within the thickness of the container body 5. In other words, the container body 5 is flat and thin, and the operating body 16 does not protrude in the thickness direction of the container body 5, so portability is not impaired. Also, as shown in FIG. 1, when the operating body 16 is displaced to the upright position, the lower wall 16g is located directly above the holder top wall portion 8f, so the operating body 16 is not pushed down even if a downward force is applied to the operating body 16. Therefore, even when carrying the ejection container 1A, the malfunction of the operating body 16 being inadvertently operated and the content liquid being ejected unintentionally can be prevented. In addition, in this state, as shown in FIG. 2(b), the cover portion 16d of the operating body 16 covers the front surface of the nozzle tip 15, so that adhesion of dust and the like to the ejection port 15a can be prevented.

In addition, as shown in Figures 1 and 2, when the cap 9 in this embodiment is attached to the container body 5, it is flush with the outer surface of the container body 5 and has no protruding parts, so the cap 9 is effectively prevented from accidentally rotating and coming off the container body 5. Also, when the operating body 16 is displaced to an upright position, as shown in Figure 1, the operating body 16 is aligned side-by-side with the cap 9. Therefore, even if an attempt is made to rotate the cap 9, the operating body 16 interferes and prevents the cap 9 from rotating, so it is possible to reliably prevent the cap 9 from falling off unintentionally.

When the liquid contents are to be ejected, the operating body 16 is rotated 90 degrees backward and displaced into a tilted position. Although not shown in the figures, when the operating body 16 is displaced into a tilted position, the lower wall 16g that prevented the operating body 16 from being pushed down is positioned forward and is no longer affected by the holder top wall 8f, so that the operating body 16 can be pushed down. Also, when the operating body 16 is displaced into a tilted position, the upper wall 16a etc. protrudes to the rear of the container body 5, and the front wall 16b extends long in the front-to-rear direction at the top of the operating body 16. In other words, the area over which the fingers can be placed to push down the operating body 16 is wider, making it easier to press downward.

When the operating body 16 is pressed down, the stem 13 is also pressed down via the head body 14, pressurizing the inside of the cylinder 11, allowing the liquid contents in the cylinder 11 to be ejected into the outside world. When pressure on the operating body 16 is released, the spring disposed in the cylinder 11 moves the piston upward together with the stem 13, reducing the pressure inside the cylinder 11, allowing the liquid contents in the storage space S to be introduced into the cylinder 11 through the pipe 12. Therefore, by repeatedly pressing and releasing the operating body 16, the liquid contents contained in the storage space S can be ejected repeatedly.

Next, a method of filling the content liquid in the ejection container 1A of this embodiment will be described. The content liquid to be filled is to be poured from the tip of the nozzle N1 shown in FIG. 3. The illustrated nozzle N1 is a nozzle provided on the pressing head of the ejection container that can drive the pump by pushing down to eject the contained content liquid in a mist (or liquid). The nozzle used to fill the content liquid is not limited to this, and may be one that ejects the content liquid using high-pressure ejection gas, for example. When filling the content liquid, first remove the cap 9 and the adapter 10 from the upper container 7. The cap 9 can be removed from the upper container 7 by rotating in a direction that releases the screw engagement between the cap side screw portion 9d and the container side screw portion 7h. In addition, the outer peripheral wall 10a of the adapter 10 is removably fitted to the left lower wall portion 7n, so it can be removed from the upper container 7 by pulling it up.

As shown in FIG. 3, the one-end opening 10c of the removed adapter 10 is inserted into the injection tube 7f. Here, the root portion 7k located at the lower end of the injection tube 7f is shaped to fit into the one-end opening 10c, so the adapter 10 is held by the root portion 7k. As shown in the figure, when the adapter 10 is held, the injection tube 7f is surrounded by the outer wall 10a, and the other-end opening 10d is located above the tip of the injection tube 7f. Therefore, the above-mentioned nozzle N1 can be inserted from the other-end opening 10d to bring the nozzle N1 closer to the injection tube 7f. The adapter 10 of this embodiment has multiple ribs 10e on the inside of the outer wall 10a, and the ribs 10e are arranged point-symmetrically with respect to the one-end opening 10c located coaxially with the injection tube 7f. Therefore, when the nozzle N1 is inserted, the ribs 10e guide the nozzle N1 toward the center of the injection tube 7f. Therefore, it is easy to align the nozzle N1 with the injection port 7g.

In addition, the ribs 10e of this embodiment have an inclined portion 10f, and the spacing between adjacent ribs 10e is wide near the other end opening 10d. In other words, the ribs 10e are less likely to get in the way when inserting the nozzle N1 into the adapter 10, making the filling operation easier.

Then, by aligning the nozzle N1 with the injection port 7g and pouring the liquid contents out of the nozzle N1, the liquid contents can be filled into the storage space S.

The nozzle N1 shown in FIG. 3 has a small outer shape (smaller than the width of the inner surface of the outer peripheral wall 10a), but even if the nozzle N2 shown in FIG. 4 has a large outer shape (larger than the width of the inner surface of the outer peripheral wall 10a), it can be inserted into the adapter 10 because the outer peripheral wall 10a is elastically deformable as described above. In other words, the adapter 10 of this embodiment can be used with nozzles of different sizes such as the nozzles N1 and N2, so even if the liquid content is used up while out and about, it can be refilled with various nozzles available at the location.

In addition, when spraying the mist of the content liquid from the nozzles N1 and N2 to inject the content liquid into the storage space S, for example, depending on the type of content liquid and the surrounding environment, the content liquid may not smoothly flow into the storage space S. If the sprayed mist of the content liquid accumulates around the injection port 7g, it may coagulate and become liquid, and may overflow from the adapter 10 during spraying or drip when the adapter 10 is removed from the injection tube 7f. On the other hand, the outer wall 10a of the adapter 10 in this embodiment is rectangular and tubular as shown in FIG. 4(a), and the nozzle N2 is cylindrical, so that there is a gap between the other end opening 10d and the nozzle N2 as shown in FIG. 4(b). Therefore, even if the sprayed mist of the content liquid does not smoothly flow into the storage space S, it can be released to the outside world from the other end opening 10d. In this embodiment, as shown in FIG. 4(d), the container side threaded portion 7h is cut out at the notch portion 7j, and a gap is provided between the base portion 7k and the one-end opening 10c by the groove portion 7m located directly below the notch portion 7j. Therefore, as shown in FIG. 4(c), the mist of the contents can escape to the outside even through the groove portion 7m. In other words, the sprayed mist of the contents is less likely to stagnate around the injection port 7g, preventing the above-mentioned problems.

Next, a second embodiment of the spray container according to the present invention will be described with reference to FIG. 5. The spray container 1B of this embodiment has an adapter 20 instead of the adapter 10 described above.

The adapter 20 has an outer peripheral wall 20a that is rectangular and cylindrical, with a width (length in the left-right direction) greater than its thickness (length in the front-rear direction) and one size larger than the left lower wall portion 7n. A connecting portion 20b is provided at the upper end of the outer peripheral wall 20a, which is inclined inward as it goes upward and then extends upward, and an adapter top wall portion 20c is provided at the upper end of the connecting portion 20b, which extends horizontally. A circular opening (one end opening 20d) is provided at the center of the adapter top wall portion 20c. A rectangular opening (other end opening 20e) is provided at the lower end of the outer peripheral wall 20a. A protrusion 20f that protrudes radially inward and fits into the left upper wall portion 7q is provided on the inner peripheral surface of the connecting portion 20b.

A number of ribs 20g are provided on the inside of the outer peripheral wall 20a and the connecting portion 20b. In this embodiment, the ribs 20g also extend from the one end opening 20d toward the corners of the outer peripheral wall 20a in a plan view, and the four ribs 20g are arranged point symmetrically with the one end opening 20d as the center. The ribs 20g also have an inclined portion 20h that approaches the center of the outer peripheral wall 20a as it moves from the bottom to the top.

As shown in Figures 5(c) to (e), the adapter 20 of this embodiment can also be attached to the upper container 7 by inserting the one-end opening 20d into the injection tube 7f. In this embodiment, the one-end opening 20d fits into the base portion 7k at the bottom of the adapter 20, and the protrusion 20f fits into the injection tube 7f at the top. In other words, the adapter 20 is held both below and above, which more reliably prevents wobbling during installation.

Although not shown, nozzles N1 and N2 of different sizes can be inserted into the adapter 20 to fill the liquid contents. The rib 20g functions in the same way as the rib 10e in the first embodiment, so the liquid contents can be filled smoothly. In this embodiment, the notch 7j and groove 7m shown in FIG. 4(d) are omitted, but the outer wall 20a of the adapter 20 is also rectangular and cylindrical as shown in FIG. 5(c), so that, as explained with reference to FIG. 4(b), even if the sprayed mist of liquid contents does not flow smoothly into the storage space S, it can escape to the outside world from the other end opening 20e.

Although one embodiment of the present invention has been described above, the present invention is not limited to the specific embodiment, and various modifications and alterations are possible within the scope of the spirit of the present invention described in the claims unless otherwise specifically limited in the above description. Furthermore, the effects of the above embodiment are merely examples of the effects resulting from the present invention, and do not mean that the effects of the present invention are limited to the above effects.

For example, in the first embodiment, the groove 7m shown in FIG. 4(d) is provided at the base 7k in this embodiment, but the same function can be achieved even if it is provided at the one-end opening 10c. In addition, the cap 9 in this embodiment can be removed from the upper container 7 when it is rotated in a direction that releases the screw engagement between the cap side screw portion 9d and the container side screw portion 7h. However, a locking mechanism may be provided to prevent accidental removal. For example, the locking mechanism may use the operating body 16. As a specific example, when the operating body 16 is in the upright position shown in FIG. 1 and FIG. 2, even if the cap 9 is rotated, the cap 9 interferes with the operating body 16 and cannot rotate, and when the operating body 16 is displaced to a tilted position and pushed down (or when the operating body 16 is displaced to a tilted position), the operating body 16 is positioned below the cap 9, allowing the cap 9 to rotate.
