Description

The present invention relates to an application container provided with an application section for applying the content liquid.

Application containers equipped with an application section for applying the contents (e.g., eyeliner, eyebrow pencil, lipstick, lip balm) have been known for some time.

For example, Patent Document 1 shows a pen-type applicator container in which an impregnated body impregnated with a liquid content is housed inside the container, and the liquid content from the impregnated body can be applied with a brush-shaped applicator provided at the tip.

JP 2012-019845 A

However, the applicator in Patent Document 1 is fixed in a direction that follows the central axis of the container. For this reason, depending on the location to be coated, the container may need to be tilted significantly in order to orient the applicator in the desired direction, making coating difficult.

In view of these problems, the present invention aims to propose an application container that is easy to use and allows the application part to be oriented in the desired direction without having to tilt the container significantly.

The present invention includes a cylindrical container having a concave spherical portion on a tip side,
An impregnated body having a rod shape, capable of being impregnated with the content liquid, and accommodated in the container;
an applicator body that is in contact with the impregnated body and has an applicator part on a tip side;
a holder that holds the applicator body and has a convex spherical portion provided on a rear end side that is movably coupled to the concave spherical portion, and that can displace the applicator body into a tilted position with respect to a central axis of the container ,
The concave spherical portion has a plurality of grooves extending in a direction circumferentially around the central axis and shifted in positions along the central axis,
The convex spherical portion is an application container having a convex portion that can be engaged with the groove portion .

A bendable pipe surrounding the impregnated body,
It is preferable that the pipe has a rear end that is airtightly held in the container, and a front end that is airtightly held in the holder.

A cover is disposed on the outer front end of the container and slidably coupled to the holder;
It is preferable that the holder has a stopper that is spaced apart from the tip of the cover when the applicator part is displaced into an upright position along the central axis and the rear end of the cover abuts the tip of the container.

a cap that surrounds the application portion and is attached to the holder;
It is preferable that the cap has a rear end portion that abuts against the tip portion of the cover when the applicator portion is displaced into an upright position along the central axis and the rear end portion of the cover abuts against the tip portion of the container.

The applicator container of the present invention has an applicator body with an applicator part at the tip side held by a holder, and the convex spherical part at the rear end of the holder is movably connected to the concave spherical part at the tip side of the container, so that the applicator part can be displaced to a tilted position with respect to the central axis of the container. In other words, the applicator container of the present invention is easy to use because the applicator part can be oriented in the desired direction without having to tilt the container significantly.

1 is a cross-sectional side view showing one embodiment of an application container according to the present invention. 2 is a half sectional view of the holder shown in FIG. 1 and a partially enlarged half sectional view of a container. 2 is a cross-sectional view of the applicator container shown in FIG. 1 in a state in which the applicator part is displaced to an upright position. 2 is a cross-sectional view of the application container shown in FIG. 1 in a state in which the application part is displaced to a tilted position.

One embodiment of an application container according to the present invention will be described below with reference to the drawings. In this specification, the up-down direction is the direction along the axis O shown in the figure. The radial direction is the direction perpendicular to the axis O in a plane perpendicular to the axis O, and the circumferential direction is the direction rotating around the axis O in this plane. In the following description, the upper side in FIG. 1 may be referred to as the "tip side" and the lower side as the "rear side". The axis O corresponds to the central axis of the container in this specification.

The application container 1 of this embodiment includes a container 2, an impregnated body 3, an application body 4, a pipe 5, a holder 6, a cover 7, and a cap 8 (consisting of an outer cap 9 and an inner cap 10).

The container 2 has a bottom wall 2a in the shape of a circular plate centered on the axis O. A cylindrical peripheral wall 2b extending upward is provided on the outer edge of the bottom wall 2a. An annular seal wall 2c with an inner diameter smaller than that of the peripheral wall 2b is provided at the connection between the bottom wall 2a and the peripheral wall 2b. The upper end of the peripheral wall 2b is referred to as the tip 2d of the container 2.

As shown in Figs. 1 and 2, a concave spherical portion 2e is provided on the upper side of the inner peripheral surface of the peripheral wall 2b. The concave spherical portion 2e is provided with a groove portion 2f that has a concave cross-sectional shape and extends around the entire circumference in a direction circumferentially around the axis O. As shown in the figure, a plurality of groove portions 2f are provided adjacent to each other in a direction along the axis O.

The impregnated body 3 is formed from a material (such as felt or foamed synthetic resin) that can be impregnated with the content liquid (such as eyeliner, eyebrow cream, lipstick, lip balm, etc.). The impregnated body 3 in this embodiment is rod-shaped with a circular cross-sectional shape and is bendable.

In this embodiment, the applicator 4 is made of a fiber bundle of synthetic resin or natural material, and the applicator part 4a located on the upper side is brush-shaped. The rear end part 4b of the applicator located on the lower side of the applicator 4 is embedded in the upper end part of the impregnated body 3 and is in contact with it. In other words, the liquid contained in the impregnated body 3 is sucked up from the rear end part 4b of the applicator by capillary action, and can be applied to the application destination by the applicator part 4a. The shape of the applicator part 4a can be appropriately selected depending on the application destination, and may be, for example, bristle-shaped or brush-shaped. The material constituting the applicator 4 can also be appropriately selected.

The pipe 5 is made of a bendable material (such as soft synthetic resin) and shaped into a cylindrical shape. As shown in the figure, the impregnated body 3 is housed inside the pipe 5. The lower end of the pipe 5 (rear end 5a) is inserted into the inside of the sealing wall 2c and is held in place by fitting therein. In this state, the outer circumferential surface of the pipe 5 and the inner circumferential surface of the sealing wall 2c are in airtight contact. Note that in this specification, "airtight" does not only mean a state in which gas cannot enter or exit, but also includes a state in which the entry or exit of gas is restricted.

The holder 6 has a holder peripheral wall 6a that is cylindrical as shown in FIG. 2. The outer peripheral surface of the holder peripheral wall 6a has an annular lower protrusion 6b that protrudes radially outward, and an upper protrusion 6c (corresponding to the "stopper" in this specification, etc.) that is located above the lower protrusion 6b, protrudes radially outward less than the lower protrusion 6b, and is inclined so that the upper surface is reduced in diameter upward. In addition, a male thread portion 6d is provided above the upper protrusion 6c on the outer peripheral surface of the holder peripheral wall 6a. In addition, a seal protrusion 6e that protrudes inward and holds the upper end (pipe tip 5b) of the pipe 5 is provided on the inner peripheral surface of the holder peripheral wall 6a. In this state, the outer peripheral surface of the pipe 5 and the seal protrusion 6e are in airtight contact. And a cylindrical holding portion 6f that is smaller in diameter than the holder peripheral wall 6a is provided at the upper end of the holder peripheral wall 6a. The holding portion 6f has the function of holding the applicator 4 with the applicator 4 protruding upward.

The holder 6 also has a convex spherical portion 6g that is integrally connected to the lower end of the holder peripheral wall 6a. The outer peripheral surface of the convex spherical portion 6g is provided with a convex portion 6h that protrudes in a semispherical shape radially outward. A plurality of convex portions 6h are provided at intervals in the circumferential direction at positions where a horizontal plane passing through the center of the convex spherical portion 6g intersects with the outer peripheral surface of the convex spherical portion 6g. The convex spherical portion 6g is formed to have the same size as the concave spherical portion 2e and is movably connected to the concave spherical portion 2e. In other words, the holder 6 can be tilted in any direction relative to the container 2. The convex portion 6h is also configured to fit into the groove portion 2f. Therefore, the tilted holder 6 is held in a position where the convex portion 6h fits into the groove portion 2f.

The cover 7 is generally cylindrical, and the upper end (tip 7a) of the cover 7 is shaped to extend radially inward to form an inward flange. The lower end (rear end 7b) of the cover 7 is shaped to expand in diameter downward. The cover 7 of this embodiment is inserted into the holder 6 from above, climbing over the upper protrusion 6c, and is slidably coupled between the upper protrusion 6c and the lower protrusion 6b.

The outer cap 9 is shaped like a closed cylinder, and has a female thread 9a on its inner surface that corresponds to the male thread 6d. The lower end of the outer cap 9 is referred to as the rear end 9b of the cap.

The inner cap 10 is a lidded cylinder with a smaller diameter than the outer cap 9. By inserting the inner cap 10 into the outer cap 9, it is held in place relative to the outer cap 9 in a non-rotating and non-removable state.

In the application container 1 in this form, the outer cap 9 can be attached to the holder 6 by screwing the male thread 6d into the female thread 9a with the application part 4a displaced to an upright position along the axis O as shown in FIG. 1. In this state, the inner peripheral surface at the lower end of the inner cap 10 abuts airtight against the outer peripheral surface of the holder 6. This prevents the application part 4a from drying out and prevents the content liquid from evaporating from the application part 4a to the outside. The impregnated body 3 containing the content liquid is surrounded by a pipe 5, and the rear end 5a of the pipe is airtightly held by the seal wall 2c, and the tip 5b of the pipe is airtightly held by the seal protrusion 6e. This also prevents the content liquid from evaporating from the impregnated body 3 to the outside of the container 2.

When the cap 8 is attached, the rear end 7b of the cover 7 abuts against the tip 2d of the container 2, and the rear end 9b of the cap of the outer cap 9 abuts against the tip 7a of the cover 7. That is, the cover 7 is slidable relative to the holder 6 as described above, but by attaching the cap 8, the cover 7 becomes non-slidable. The cover 7 slides when changing the position of the application part 4a, as described below. If the cover 7 is in a slidable state, there is a risk that the position of the application part 4a will change, but by attaching the cap 8, unintended changes in the position of the application part 4a can be prevented.

When applying the liquid content with the application part 4a, the cap 8 is rotated relative to the container 2 to loosen the male threaded part 6d and the female threaded part 9a, and the cap 8 is removed. Immediately after removing the cap 8, the application part 4a is in an upright position as shown in FIG. 3. Therefore, it can be used like a conventional application container such as that of Patent Document 1 mentioned above.

On the other hand, when the application part 4a is in an upright position, if the container 2 needs to be tilted significantly to orient the application part 4a in the desired direction, the cover 7 is grasped and tilted relative to the container 2. As described above, the holder 6 to which the cover 7 is attached can be tilted in any direction relative to the container 2 as shown by the solid and imaginary lines in FIG. 4 because the convex spherical part 6g is movably connected to the concave spherical part 2e. Here, since the cover 7 is slidable relative to the holder 6, the rear end 7b of the cover 7 does not interfere with the front end 2d of the container 2 to prevent the holder 6 from being tilted. In addition, since the holder 6 is provided with an upper protrusion 6c, the slid cover 7 will not fall off the holder 6. In addition, since both the impregnated body 3 and the pipe 5 are bendable, they do not hinder the holder 6 from being tilted.

The applicator container 1 of this embodiment is configured so that the convex portion 6h on the convex spherical portion 6g fits into the groove portion 2f on the concave spherical portion 2e. The groove portion 2f is provided in a plurality of portions in a direction along the axis O, and the convex portions 6h are provided in a plurality of portions spaced apart in the circumferential direction. Therefore, in the range where the convex portions 6h and the groove portions 2f engage, regardless of the direction in which the applicator portion 4a is tilted, the position is maintained at the angle at which it was tilted.

As described above, according to the application container 1 of this embodiment, the application part 4a can be tilted to any desired position, so that the application part 4a can be oriented in a desired direction without tilting the container 2 significantly, making application work easy and easy to use.

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 changes 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 above-described embodiment, the inclination of the holder 6 relative to the container 2 is maintained by the convex portion 6h and the groove portion 2f, but the inclination of the holder 6 may be maintained without the convex portion 6h and the groove portion 2f by increasing the sliding resistance between the concave spherical portion 2e and the convex spherical portion 6g. Also, in the above-described embodiment, the groove portion 2f extends around one circumference in a direction circling the axis O, but it may be provided partially in a direction circling the axis O corresponding to the position where the convex portion 6h is provided.
