Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, while the applicator-tipped cap is removed from the container and the content liquid is being applied, the container is in an open state, so the content liquid stored in the container gradually volatilizes. That is, as the number of times or the time of applying the content liquid increases, the viscosity of the content liquid becomes higher, making it difficult to spread the content liquid over the application target. For this reason, for example, in a container storing a content liquid whose viscosity decreases as the temperature rises, when the viscosity of the content liquid becomes high and it becomes difficult to spread it, the container is heated in a hot water bath to warm the content liquid. However, to perform a hot water bath, not only must an instrument for that purpose be prepared, but it also takes time. For this reason, even when there is still content liquid remaining in the container, the container is often discarded as it is, and there is also a problem in that resources are not used effectively.

[0005] An object of the present invention is to solve such problems, and it is an object to provide a coating container that can maintain the viscosity of the stored content liquid even when the number of times or the time of applying the content liquid increases as compared with the prior art.

Means for Solving the Problems

[0006] The present invention is a coating container comprising a container for storing a content liquid inside an upper-open mouth portion, and an applicator-tipped cap having a shaft portion extending inside the mouth portion and an applicator at the tip of the shaft portion, wherein the container includes a container body having the mouth portion and a storage space for the content liquid, and a squeegee piece capable of scraping off the content liquid adhering to the applicator, and an elastic deformable partition having a slit, provided closer to the storage space than the squeegee piece, and when the applicator-tipped cap is attached to the mouth portion, the slit is opened to allow the shaft portion to pass through, while when the applicator-tipped cap is removed from the mouth portion, the slit is closed to close the storage space, and a slit valve. Coating portion The partition includes a cylindrical portion and a bulging portion that is connected to the lower end portion of the cylindrical portion and protrudes so as to bulge toward the storage space. 、 The partition It is held on the inner peripheral surface of the mouth portion and extends downward along the inner peripheral surface to the lower part of the mouth portion has a cylindrical portion and is connected to the lower end portion of the cylindrical portion and before towards the storage space downward bulges so as to protrude portion and is provided with a bulging portion, and the inner surface of the bulging portionis provided on the entire bottom surface of the cylindrical portion that receives the content liquid from below and extends over the entire bottom surface The cross-sectional shape is an arc without corners shape and has a storage space for storing the content liquid inside the partition wall The diameter of the inner peripheral surface of the cylindrical portion and the diameter of the arc shape are larger than the width of the coating portion It is an application container

[0008] It is preferable that the slit valve has a gap between the slit and the shaft portion when the shaft portion is inserted therethrough

Advantages of the Invention

[0009] The application container of the present invention is provided with a slit valve. When the cap with an applicator is removed from the mouth portion, the slit is closed to close the storage space of the content liquid. Therefore, compared with the conventional one, the volatilization of the stored content liquid can be suppressed. That is, according to the application container of the present invention, since the viscosity of the content liquid can be maintained, it is not necessary to warm it as in the conventional case, and it can be used without taking much trouble. In addition, since the content liquid can be used up as much as possible, it is excellent in that resources can be used without waste

Modes for Carrying Out the Invention

[0011] Hereinafter, an embodiment of the coating container (coating container 10) according to the present invention will be described with reference to the drawings. In this specification and the like, the "upper" direction and the "lower" direction refer to the directions in the state where the coating container 10 is in an upright posture as shown in FIG. 1 (the state where the container body (reference numeral 1) is located below and the lid body (reference numeral 3) is located above).

[0012] The coating container 10 of the present embodiment includes a container body 1 and a wiping member 2 as constituting the "container" in this specification and the like. Further, the coating container 10 includes a lid body 3, a shaft member 4, and an applicator 5 as constituting the "cap with an applicator" in this specification and the like.

[0013] The container body 1 is formed in a bottomed cylindrical shape. Specifically, it includes a bottom portion 1a having a disc shape and curved upward at the central portion, a cylindrical body portion 1b rising upward from the edge portion of the bottom portion 1a, a cylindrical mouth portion 1c that is open at the upper end and has a lower end connected to the body portion 1b and an outer diameter smaller than that of the body portion 1b, and a male screw portion 1d provided on the outer peripheral surface of the mouth portion 1c. Further, a space (accommodation space) S is partitioned inside the mouth portion 1c, and a content liquid L such as lip gloss is accommodated in this accommodation space S as shown in FIG. 2.

[0014] The squeezing member 2 is formed of a soft member such as rubber or elastomer and can be elastically deformed. The squeezing member 2 of the present embodiment is attached inside the mouth portion 1c. When the lid body 3 is attached to the mouth portion 1c, it elastically deforms to form the shape shown in FIG. 1, and when the lid body 3 is removed from the mouth portion 1c, it restores to form the shape shown in FIG. 3. Specifically described with reference to FIG. 3, the initial shape of the squeezing member 2 attached to the mouth portion 1c includes a flange portion 2a extending in the horizontal direction and contacting the upper end portion of the mouth portion 1c, a cylindrical portion 2b extending downward along the inner peripheral surface of the mouth portion 1c from the inner edge portion of the flange portion 2a, and a bulging portion 2c connected to the lower end portion of the cylindrical portion 2b and protruding such that the lower end bulges toward the accommodation space S. Here, the inner space partitioned by the cylindrical portion 2b and the bulging portion 2c is referred to as a storage space T. Also, in the present embodiment, the cylindrical portion 2b and the bulging portion 2c constitute the "partition wall" in this specification and the like.

[0015] And the bulging portion 2c is provided with a slit 2d extending through the bulging portion 2c. As shown in the cross-section taken along the line B-B in FIG. 3, the slit 2d of the present embodiment is formed by two linearly extending slit portions intersecting at the central portion of the bulging portion 2c to form a cross shape, separating the central portion of the bulging portion 2c into four parts. Since the bulging portion 2c is elastically deformable, although the slit 2d is normally closed, when a force is applied to the bulging portion 2c, the portions separated by the slit 2d elastically deform and the slit 2d opens. That is, the bulging portion 2c and the portion where the slit 2d is provided in the squeezing member 2 function as a slit valve.

[0016] Also, the squeegee member 2 has a squeegee piece 2e that protrudes radially inward from the inner peripheral surface of the cylindrical portion 2b above the bulging portion 2c and is inclined downward as it extends radially inward. As will be described later, the squeegee piece 2e is used to scrape off the excess content liquid L adhering to the applicator 5. And on the outer peripheral surface of the cylindrical portion 2b, there is a retaining projection 2f that engages with the lower end portion of the mouth portion 1c when the squeegee member 2 is attached to the mouth portion 1c, and retains the squeegee member 2 so as not to come off with respect to the mouth portion 1c.

[0017] As shown in FIG. 3, in the state where the lid body main body 3 is removed from the mouth portion 1c, the slit 2d of the squeegee member 2 of the present embodiment is closed. For this reason, the accommodation space S is closed with respect to the outside. On the other hand, as shown in FIG. 2, in the state where the lid body main body 3 is attached to the mouth portion 1c, since the portion separated by the slit 2d in the bulging portion 2c is elastically deformed, the slit 2d is opened as shown in the figure, and the shaft member 4 is inserted through the squeegee member 2.

[0018] As shown in FIG. 1, the lid body main body 3 has a lid-shaped cylindrical shape. The lid body main body 3 of the present embodiment includes a disk-shaped top wall 3a and a cylindrical outer peripheral wall 3b that extends downward from the outer edge portion of the top wall 3a. Further, on the inner peripheral surface of the outer peripheral wall 3b, a female screw portion 3c corresponding to the male screw portion 1d is provided.

[0019] The shaft member 4 includes an upper annular wall 4a having a circular cylindrical shape. The upper annular wall 4a is formed so as to fit on the inner peripheral surface of the outer peripheral wall 3b, and thereby the shaft member 4 is held by the lid body main body 3. A disk-shaped wall 4b is connected to the lower end portion of the upper annular wall 4a, and a columnar shaft portion 4c that extends downward is provided at the center portion of the disk-shaped wall 4b. And at the tip of the shaft portion 4c, a fitting hole 4d for holding the applicator 5 is provided.

[0020] The applicator 5 includes an application part 5a for applying the content liquid, and an applicator holding part 5b that has a cylindrical shape and is inserted into the fitting hole 4d to hold the applicator 5 on the shaft member 4. The application part 5a is provided, for example, in a brush shape, a sponge shape, or a pen shape, and an optimal one is appropriately selected according to the type of the content liquid and the part where the content liquid is to be applied.

[0021] In such a form, the coating container 10 is stored by screwing the male screw part 1d and the female screw part 3c together and attaching the lid body 3 to the mouth part 1c as shown in FIG. 2. In this state, the flange part 2a of the squeezing member 2 is sandwiched between the upper end part of the mouth part 1c in the container body 1 and the disk-shaped wall 4b of the shaft member 4. Therefore, the volatilization of the content liquid L stored in the storage space S can be suppressed. In this state, since the tip of the squeezing piece 2e also abuts against the outer peripheral surface of the shaft part 4c, the volatilization of the content liquid L can be further suppressed.

[0022] Also in this state, as shown in FIG. 2, the part separated by the slit 2d in the bulging part 2c is elastically deformed and elastically abuts against the shaft part 4c. Therefore, even if the coating container 10 is dropped or laid on its side, it is less likely that the content liquid L in the storage space S will flow into the squeezing piece 2e side beyond the bulging part 2c that abuts against the shaft part 4c. That is, the bulging part 2c also effectively functions to prevent the problem that the content liquid L overflows from the coating container 10 due to dropping or the like.

[0023] By the way, since the slit 2d of the present embodiment is cross-shaped and the outer shape of the shaft part 4c is circular, when the shaft part 4c is inserted through the slit 2d, as shown in the A-A cross section of FIG. 2, a gap G is formed between the outer end of the slit 2d and the shaft part 4c. On the other hand, the gap G of the present embodiment is minute, and even if the content liquid L in the storage space S flows toward the bulging part 2c due to dropping or the like, it is difficult for the gap G to pass through, and the flow into the squeezing piece 2e side is suppressed. Therefore, the effect of preventing the problem that the content liquid L overflows from the coating container 10 described above is ensured.

[0024] When applying the content liquid L, the lid body 3 is rotated with respect to the container body 1 to release the screwing engagement between the male screw portion 1d and the female screw portion 3c, and the lid body 3 is directly pulled upward. As a result, the shaft member 4 can be pulled out from the squeezing member 2. Here, since the tip of the squeezing piece 2e is in contact with the outer peripheral surface of the shaft portion 4c, by pulling out the shaft member 4 from the squeezing member 2, the content liquid L adhering to the outer peripheral surface of the shaft member 4 can be scraped off. When the applicator 5 attached to the tip of the shaft member 4 passes through the bulging portion 2c, the elastically deformed bulging portion 2c is restored and the slit 2d is closed. For this reason, the scraped-off content liquid L will accumulate in the storage space T.

[0025] Then, as shown in FIG. 4, by further pulling up the lid body 3, the content liquid L adhering to the periphery of the applicator 5 can also be scraped off by the tip of the squeezing piece 2e. After the applicator 5 is pulled out from the squeezing member 2, if there is excess content liquid L remaining on the applicator 5, the content liquid L can be further scraped off by rubbing the applicator 5 against the squeezing piece 2e, so that an appropriate amount of the content liquid L can be made to adhere to the applicator 5. In this way, the content liquid L scraped off from the applicator 5 is also stored in the storage space T.

[0026] After pulling up the lid body 3 as described above and pulling out the shaft member 4 and the applicator 5 from the squeezing member 2, with the lid body 3 pinched by the finger, the content liquid L adhering to the tip of the applicator 5 can be applied to the application destination (see FIG. 5).

[0027] Incidentally, while the content liquid L is being applied with the applicator 5, although the lid body 3 is also removed from the mouth portion 1c, in this embodiment, since the slit 2d is closed, the storage space S can be closed to the outside. Therefore, even when it takes time to apply the content liquid L, volatilization of the content liquid L stored in the storage space S can be effectively prevented. Particularly in this embodiment, since the scraped-off content liquid L is stored in the storage space T, the slit 2d is surely closed by the accumulated content liquid L (liquid sealing effect). Therefore, volatilization of the content liquid L stored in the storage space S can be more effectively prevented.

[0028] When applying the content liquid L with the applicator 5, there may be a case where the content liquid L is scraped off too much or the content liquid L becomes insufficient during application, and it is desired to reattach the content liquid L to the applicator 5. In such a case, conventionally, it has been necessary to insert the applicator 5 into the mouth portion 1c again. Particularly when the content liquid L remaining in the storage space S is small, it takes time because the lid body 3 has to be rotated until the male screw portion 1d and the female screw portion 3c are screwed together to the end. On the other hand, according to the application container 10 of this embodiment, as shown in FIG. 6, the content liquid L accumulated in the storage space T can be attached to the applicator 5, so that such time-consuming work is not required and it is excellent in terms of usability.

[0029] After the application of the content liquid L is completed, the applicator 5 is inserted inside the squeezing member 2, and as shown in FIG. 2, the male screw portion 1d and the female screw portion 3c are screwed together as before. In this state, as described above, the bulging portion 2c is elastically deformed and in contact with the shaft portion 4c, and also the gap G shown in the A-A cross section of FIG. 2 is minute. Therefore, even if the application container 10 is dropped, it is possible to prevent the problem that the content liquid L overflows to the outside.

[0030] In addition, leakage of the content liquid L due to dropping or the like can also be prevented by the squeegee piece 2e that abuts against the shaft portion 4c and the flange portion 2a that is sandwiched between the upper end portion of the mouth portion 1c and the disc-shaped wall 4b. Therefore, for example, when the leakage of the content liquid L can be sufficiently prevented by these, the gap G may be increased. When increasing the gap G in this way, even if the content liquid L is accumulated in the storage space T as shown in FIGS. 4 and 5, by inserting the applicator 5 inside the squeegee member 2, it can be returned from the formed gap G to the accommodation space S.

[0031] As described above, one embodiment of the present invention has been described. However, the present invention is not limited to such a specific embodiment, and various modifications and changes are possible within the scope of the gist of the present invention described in the claims, unless otherwise particularly limited in the above description. In addition, the effects in the above embodiments 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.

[0032] For example, although the slit 2d of the present embodiment is cross-shaped, it may be a single linear slit. In other words, the cross-shaped slit 2d of the present embodiment can be said to be such that, as shown in the cross-sectional view taken along line B-B in FIG. 3, four slit portions extend radially outward from the intersecting portion. However, the number of slit portions is not limited to four, and may be three or less or five or more. Further, the slit 2d is not limited to extending linearly from the bulging portion 2c, and may extend in a curved shape. In the present embodiment, the portion where the slit 2d is provided is the bulging portion 2c that protrudes so as to bulge toward the accommodation space S. However, the shape of this portion can also be variously changed. For example, it may protrude flat toward the accommodation space S (the portion where the slit 2d is provided is flat). In addition, in the present embodiment, the members configured by two or more may be configured by one member, or conversely, the number of members may be increased compared to the present embodiment.
