Description

The present invention relates to a coating container equipped with an applicator for applying a content liquid.

BACKGROUND ART As a container for storing liquid contents such as lip gloss, nail polish, mascara, eyeliner, etc., there is known an application container equipped with a brush-like or brush-like applicator as shown in Patent Document 1, for example. Such applicator containers have an applicator at the tip of the shaft and a cap with an applicator that is attached to the container containing the liquid content, so it is not necessary to use a separate applicator when applying the liquid content. There is no need to prepare anything and it is very convenient. Furthermore, by attaching the cap with applicator to the mouth part, the liquid content can be attached to the applicator, so the cap with applicator can be removed and the liquid can be applied immediately.

By the way, many conventional coating containers are relatively long, and even if they are carried around for use, they may not be able to be accommodated in the pouch, or even if they are able to be accommodated, they may get caught in the pouch when taken out. Note that some application containers are relatively short in length so that they can be accommodated in a pouch or the like. However, in this case, the length of the shaft to which the applicator is attached becomes shorter, and the distance between the hand holding the applicator cap and the applicator gets closer, so when applying mascara or eyeliner, for example, it becomes difficult to apply the applicator. It was difficult to use because the hand holding the cap came into contact with the face.

The present invention aims to solve these problems, and since the overall length of the container can be shortened, it can be conveniently used especially when being carried, and the length from the handle to the applicator can be shortened. To provide a coating container that is easy to use even when coating is easier at a certain distance.

The present invention is a coating container comprising a container that stores a liquid inside a mouth opening at the top, and a cap with an applicator that has an applicator at the tip of a shaft and is attached to the mouth. , the cap with applicator has a lidded cylindrical shape including a top wall and a peripheral wall connected to the top wall, and includes a cap main body portion into which the mouth portion is inserted through a lower opening and held in the mouth portion; a holding portion provided inside the main body portion and holding the shaft portion slidably between a storage position near the top wall and an extended position near the lower opening ; and a holding portion separated from a side surface of the shaft portion. The shaft part is elastically deformable in the direction in which the shaft part is moved to the extended position, and is elastically deformed in the direction away from the shaft part to allow the shaft part to slide, while the shaft part is in the extended position. The container includes a stopper portion that engages with the shaft portion to prevent the shaft portion from sliding when the container moves, and the container has a stopper portion that scrapes the content liquid adhering to the applicator from the inside of the mouth portion. An ironing piece that can be dropped is provided, the shaft portion has a protrusion that projects radially outward from the side surface, the ironing piece has an inner end portion that presses against the side surface of the shaft portion, and the ironing piece has an inner end portion that presses against the side surface of the shaft portion; The end portion engages with the protrusion in a sliding direction of the shaft portion when the cap with applicator is removed from the mouth portion, and slides the shaft portion from the storage position to the extended position. It is a coating container in which the stopper part is engaged with the shaft part .

The cap with an applicator has a sealing part attached to the holding part, and the sealing part has an inner end that comes into liquid-tight contact with a side surface of the shaft part, and a cap with an applicator that connects the cap with an applicator to the opening. It is preferable to have an outer end portion that contacts the mouth portion in a liquid-tight manner when the outer end portion is attached to the mouth portion.

According to the application container of the present invention, the length of the shaft protruding from the cap body can be shortened by sliding the shaft to the storage position near the top wall, so the length of the container can be shortened accordingly. This makes it possible to shorten the length and realize a size that is easy to carry. In addition, when in use, sliding the shaft to the extended position near the bottom opening increases the length of the shaft protruding from the cap body, so it is best to keep the applicator relatively far away from the cap body. It can be used well even in cases where the liquid is easy to apply.

As shown in FIG. 1, the sealing member 5 of the present embodiment has a portion that is located radially inward in a cross-sectional view and has a roughly J-shape, and a portion that protrudes radially outward from the upper end of this portion. It has a shape that looks like a combination of these rotated around the axis O. The inner peripheral surface of the seal member 5 is provided with an annular recess 5a that engages with a protrusion 4g provided on the holding member 4, and thereby the seal member 5 is held on the holding member 4. Here, the inner end portion 5b located on the radially inner side of the seal member 5 has a shape that bulges radially inward as shown in the figure, and when assembled as the application container 10, the inner end portion 5b is located on the radially inner side. It is pressed elastically against the side surface of the member 6. Further, the outer end portion 5c located on the radially outer side of the sealing member 5 is held between the upper end portion of the mouth portion 1c and the flange wall 4e when the coating container 10 is assembled. Note that, as will be described later, the inner end portion 5b and the outer end portion 5c each exhibit a sealing function for different locations. As described above, according to the sealing member 5 of this embodiment, one member can perform the sealing function at two locations, so the number of parts can be reduced compared to the case where one member is provided at each location. can do.

The shaft member 6 corresponds to the "shaft section" in this specification and the like. The shaft member 6 includes a cylindrical shaft body 6a extending along the axis O, and a large-diameter shaft body 6a that is provided at the upper end of the shaft body 6a and has a larger diameter than the shaft body 6a. 6b. The outer diameter of the large diameter portion 6b is slightly smaller than the inner diameter of the cylindrical portion 4a, but larger than the gap between the locking protrusions 4d facing each other with the axis O in between. Further, the outer diameter of the shaft body 6a is slightly smaller than the inner diameter of the support portion 4h of the holding member 4. With such a configuration, the shaft member 6 can be moved along the axis O with respect to the holding member 4, with the large diameter portion 6b being supported by the cylindrical portion 4a and the shaft main body 6a being supported by the support portion 4h. It can be slid. As shown in FIG. 1, the position where the large diameter portion 6b has moved toward the top wall 3a is referred to as the "storage position," and as shown in FIG. "Extended position".

Further, the shaft member 6 includes a protruding portion 6c having a larger diameter than the shaft main body 6a on the side surface of the shaft main body 6a. The protrusion 6c of this embodiment is provided at a position where its upper end engages with the inner end of the squeezing piece 2b when the cap body 3 is attached to the container body 1 as shown in FIG. (See partial enlarged view in Figure 1). Further, a fitting hole 6d for holding the applicator 7 is provided at the lower end of the shaft main body 6a.

The applicator 7 includes an applicator part 7a for applying the liquid content, and an applicator holding part 7b that is cylindrical and inserted into the fitting hole 6d to hold the applicator 7 on the shaft member 6. The applicator 7a is provided, for example, in the shape of a brush, sponge, or brush, and the most suitable one is selected depending on the type of liquid content and the area to which the liquid content is to be applied.

As shown in FIG. 1, the coating container 10 configured with the above-mentioned members has a container main body 1 and a squeezing member 2 with a flange portion 2a engaged with the inner circumferential surface of the mouth portion 1c. assembled as a container. In addition, the cap body 3, the holding member 4, the sealing member 5, the shaft member 6, and the applicator 7 are constructed by, for example, inserting the shaft member 6 into the holding member 4 from above, and then engaging the recess 5a with the projection 4g. Then, attach the seal member 5 to the holding member 4, and further engage the engagement recess 3e and the engagement protrusion 4b, and engage the upper part of the flange wall 4e in the gap between the vertical rib 3f and the inward protrusion 3g. By attaching the holding member 4 to the cap body 3, it is assembled as a "cap body" in this specification and the like. Note that the method of assembling these members can be changed as appropriate and is not limited to the method described above.

The application container 10 assembled in this manner is stored with the male threaded portion 1d and the female threaded portion 3h screwed together and the cap body 3 attached to the mouth portion 1c, as shown in FIG. In this state, the outer end 5c of the sealing member 5 is held between the upper end of the mouth 1c of the container body 1 and the flange wall 4e, so that the liquid contained in the storage space S leaks to the outside. and volatilization can be suppressed. Further, in this state, since the inner end of the squeezing piece 2b is elastically pressed against the side surface of the shaft member 6, leakage and volatilization of the content liquid to the outside can be further suppressed.

Further, in this state, the shaft member 6 has moved to the retracted position where the large diameter portion 6b is located closer to the top wall 3a, and the length of the shaft member 6 protruding from the cap body 3 is shortened. That is, since the length of the container body 1 (the length along the axis O) can be shortened as shown, the application container 10 can be formed in a compact size that is easy to carry.

To apply the liquid content, the cap body 3 is rotated relative to the container body 1 to unscrew the male threaded portion 1d and the female threaded portion 3h, and the cap body 3 is pulled up as shown in FIG. In this state, the inner end of the squeezing piece 2b elastically presses against the side surface of the shaft main body 6a and is engaged with the upper end of the protrusion 6c, so even if the cap main body 3 is pulled up, the shaft remains The member 6 will remain at that height. That is, the shaft member 6 can be slid so as to be pulled out from the cap body 3. Here, when the shaft member 6 slides as shown in FIG. Since the stopper piece 4c provided with the stopper piece 4d is elastically deformed in a direction away from the axis O, sliding of the shaft member 6 is not hindered.

Then, when the cap body 3 continues to be pulled up and the large diameter portion 6b comes into contact with the upper surface of the support portion 4h, the shaft member 6 stops sliding, and the shaft member 6 is pulled out together with the applicator 7 from the squeezing piece 2b. It is removed from the container body 1 (see FIG. 4). That is, by performing an operation to remove the cap body 3 from the container body 1, the shaft member 6 can be moved to the extended position.

In this state, the large diameter portion 6b is located below the locking protrusion 4d, and the stopper piece 4c, which had been elastically deformed in a direction away from the axis O, is restored to its original state. There is. That is, since the gap between the opposing locking protrusions 4d is smaller than the outer diameter of the large diameter portion 6b, the shaft member 6 can be prevented from easily sliding upward with respect to the cap body 3. That is, as shown in FIG. 5, the shaft member 6 does not slide when the cap body 3 is moved little by little, for example when applying mascara, so the shaft member 6 can be used with the same feeling as the conventional one in which the length of the shaft does not change. can do. In addition, the length of the shaft member 6 protruding from the cap body 3 is increased, and the distance from the cap body 3 to the applicator 7 is increased, making it difficult for the fingers holding the cap body 3 to touch the face, allowing the content liquid to be applied well. be able to.

When the amount of liquid adhering to the applicator 7 has decreased, the applicator 7 can be inserted into the container body 1 to reapply the liquid thereto, as shown in FIG. Moreover, when the content liquid has adhered in excess, the excess content liquid can be scraped off by rubbing the applicator 7 on the squeezing piece 2b. In addition, when inserting the applicator 7 into the container body 1 to re-deposit the content liquid, the applicator 7 and the shaft member 6 will elastically press against the inner end of the squeezing piece 2b, as described above. As described above, since the gap between the locking protrusions 4d is smaller than the outer diameter of the large diameter portion 6b, the shaft member 6 does not easily slide with respect to the cap body 3.

After the application of the content liquid is completed, as shown in FIG. 7, the applicator 7 is inserted into the container main body 1, and the cap main body 3 is pushed down so that the applicator 7 presses against the bottom 1a. In this state, a strong upward force acts on the shaft member 6, so the large diameter portion 6b presses against the locking protrusion 4d and elastically moves the stopper piece 4c in a direction away from the axis O. Transform. As a result, the engagement between the locking protrusion 4d and the large diameter portion 6b is disengaged, and the shaft member 6 rises relative to the cap body 3. Thereafter, the cap body 3 can be attached to the mouth portion 1c by rotating the cap body 3 and screwing the male threaded portion 1d and the female threaded portion 3h.

Note that if the content liquid adheres to the side surface of the shaft member 6, when the shaft member 6 rises relative to the cap body 3, the content liquid will enter the inside of the cylindrical portion 4a and solidify thereafter. Therefore, the shaft member 6 may not be able to slide smoothly. On the other hand, in this embodiment, since the inner end portion 5b of the sealing member 5 elastically presses against the side surface of the shaft member 6, it is possible to prevent the content liquid from entering inside the cylindrical portion 4a.

Although one embodiment of the present invention has been described above, the present invention is not limited to such specific embodiment, and unless specifically limited by the above explanation, the gist of the present invention described in the claims Various modifications and changes are possible within the range. Furthermore, the effects of the embodiments described above are merely illustrative 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 this embodiment, as a structure for preventing the shaft member 6 from sliding when moved to the extended position, the interval between the locking protrusions 4d of the opposing stopper pieces 4c is set to be smaller than the outer diameter of the large diameter portion 6b. However, it is not limited to this. As an example of realizing such a function with another configuration, the stopper can be moved away from the axis O by making the interval between the locking protrusions 4d of the stopper piece 4c smaller than the outer diameter of the shaft main body 6a. In addition to bending the piece 4c, a recess into which the locking protrusion 4d is fitted in the extended position is provided on the side surface of the shaft main body 6a, so that when the shaft member 6 is moved toward the extended position, the stopper piece 4c is bent. The locking protrusion 4d may be fitted into the recess with the elastic force of the locking protrusion 4c. Further, in the embodiment described above, the coating container 10 was configured with seven members, but the number of members may be reduced by combining several members, or one member may be divided into a plurality of parts.
