Description

[Technical field]

[0001] The present invention relates to an application container equipped with an applicator for applying a liquid contained therein. [Background technology]

[0002] 2. Description of the Related Art For example, in the case of containers that store liquid contents such as nail polish, pedicure, liquid lip balm, and mascara, application containers equipped with an applicator for applying the liquid contents to nails, lips, etc. are known.

[0003] Such applicator containers generally have a cap that is detachably attached to the container body and a shaft part that has an applicator attached to the tip of the shaft part, as shown in Patent Documents 1 and 2. Here, the shaft part is shaped long enough that the applicator can reach the bottom of the container body so that the content liquid adheres to the applicator when the cap is closed, even if the amount of content liquid contained in the container body becomes low.

[0004] [Patent Document 1] JP 2012-30822 A [Patent Document 2] JP 2003-175961 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, when the stem is long, the distance between the part where the cap is held with the fingers and the applicator at the tip of the stem increases, making it difficult to move the applicator as intended, and sometimes preventing the content liquid from being applied as intended.

[0006] The present invention has an object to solve such problems, and aims to provide an applicator container which, when a cap is attached to the container body, allows the liquid contents to be applied to an applicator as in the conventional case, and which makes the task of applying the liquid contents with the applicator easier than before. [Means for solving the problem]

[0007] The present invention relates to a container body having an opening at the top and capable of containing a liquid in a storage space connected to the opening; A top wall covering the mouth portion; A first threaded portion is screwed into the mouth portion, The ceiling wall is formed a mounting body having an insertion hole that opens in a direction along the axis of the mouth portion and a groove that extends along the axis; a cap attached to the mounting body so as to be rotatable around the axis, the cap having a second threaded portion on the outside of the groove; a shaft body extending along the axis and inserted into the insertion hole, the shaft body having a lower end provided with an applicator for applying the content liquid, and an upper end provided with a protrusion that screws into the second screw portion via the groove; The shaft body is inserted into the annular shape. The O-ring is a seal member that is slidable on an outer circumferential surface of the shaft body and that is in liquid-tight contact with the outer circumferential surface of the shaft body; Roughly ring-shaped, a holder that holds the seal member below the top wall and is held by the mounting body, The holder is provided with an annular recess on an upper portion of the holder on an inner side in a radial direction, The seal member is held by the holder along a radial direction of the shaft body and an extension direction of the shaft body so as to be fitted into the annular recess, When the cap is rotated with the attachment attached to the mouth portion, the shaft moves along the axis toward the cap, and the attachment rotates, disengaging the first threaded portion from the mouth portion.This is an application container.

[0008] The pitch of the second threaded portion is preferably greater than the pitch of the first threaded portion.

[0009] The outer peripheral wall of the mounting body is preferably surrounded by the outer peripheral wall of the cap.

[0010] It is preferable that the outer peripheral wall of the mounting body and the outer peripheral wall of the cap are both exposed to the outside world.

[0011] It is preferable that the cap comprises a cap body that is prevented from coming off from the mounting body and is rotatably attached in a direction around the axis, and a cylindrical body that is located outside the groove portion, has the second screw portion on its inner surface, and is attached non-rotatably to the cap body. Effect of the Invention

[0012] According to the applicator of the present invention, when the attachment or the like is attached to the mouth of the container body, the content liquid can be applied to the applicator provided at the lower end of the shaft in the same manner as in the past, even if the content liquid is reduced. Then, when the cap is rotated with the attachment attached to the mouth of the container body, the shaft with the applicator provided at the lower end moves toward the cap, and the attachment rotates, releasing the screw engagement between the first screw portion and the mouth. In other words, when the cap is removed from the container body, the shaft moves toward the cap, and the part of the cap that is pinched with the fingers and the applicator are brought closer together, making it easier to apply the content liquid with the applicator.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, a first embodiment of the application container according to the present invention (application container 100) will be described with reference to the drawings. In this specification and the like, the "upper" and "lower" directions refer to the directions in a state where the application container 100 is in an upright position (where the container body (reference symbol 1) is located at the bottom and the cap body (reference symbol 6) is located at the top) as shown in FIG.

[0015] The application container 100 of this embodiment includes a container body 1, an attachment body 2, a holder 3, a sealing member 4, a packing 5, a cap body 6, a cylindrical body 7, an axis body 8, and an application tool 9. The cap body 6 and the cylindrical body 7 of this embodiment are members that constitute the cap of the present invention.

[0016] The container body 1 is generally cylindrical with a bottom, and includes a circular bottom 1a with the center protruding upward, a body 1b that rises upward from the outer edge of the bottom 1a in a cylindrical shape and has a reduced diameter at the top, a cylindrical mouth 1c that rises upward from the reduced diameter body 1b and is open at the top, and a male screw-like mouth thread portion 1d provided on the outer circumferential surface of the mouth 1c. Here, the center lines of the bottom 1a and body 1b coincide with the axis O of the mouth 1c. The space (storage space S) partitioned by the bottom 1a, body 1b, and mouth 1c can store a liquid content such as nail polish or mascara.

[0017] The mounting body 2 includes a disk-shaped top wall 2a extending horizontally, and a cylindrical outer peripheral wall 2b extending downward from the outer edge of the top wall 2a and having a center line common to the axis O. A circular insertion hole 2c opening in a direction along the axis O is provided in the center of the top wall 2a. A first screw portion 2d in the form of a female screw is provided on the inner peripheral surface of the outer peripheral wall 2b, which is screwed into the opening screw portion 1d. A lower engaging protrusion 2e protruding radially outward is provided on the lower portion of the outer peripheral surface of the outer peripheral wall 2b. In addition, a cylindrical upper tube portion 2f extending upward and having a center line common to the axis O is provided on the top wall 2a radially outward of the insertion hole 2c (see cross section AA in FIG. 1), and groove portions 2g that cut the upper tube portion 2f in the vertical direction are provided opposite to each other across the axis O.

[0018] The holder 3 is generally ring-shaped and is held by the outer circumferential wall 2b below the top wall 2a of the mounting body 2. An annular recess 3a is provided around the axis O at the upper radially inner portion of the holder 3.

[0019] The seal member 4 is annular and made of a soft material such as rubber, and an O-ring is used in this embodiment. The seal member 4 is inserted into the shaft body 8 and held by the holder 3 so as to fit into the annular recess 3a.

[0020] The packing 5 has an annular plate shape and is made of a soft material such as rubber. The packing 5 in this embodiment is fitted inside the attachment body 2 below the holder 3 attached to the attachment body 2. When the first screw portion 2d is screwed into the mouth screw portion 1d of the attachment body 2 as shown in FIG. 1, the packing 5 is sandwiched in the vertical direction between the mouth portion 1c and the holder 3 to prevent leakage of the content liquid contained in the storage space S and to prevent outside air from entering the storage space S.

[0021] The cap body 6 is generally cylindrical with a lid and includes a disk-shaped top wall 6a extending horizontally and a cylindrical outer peripheral wall 6b extending downward from the outer edge of the top wall 6a and having a common center line and axis O. The outer peripheral wall 6b surrounds the outer peripheral wall 2b of the mounting body 2 from below and can rotate relative to the outer peripheral wall 2b. As shown in the partially enlarged view of FIG. 1, the inner peripheral surface of the outer peripheral wall 6b is provided with inward claws 6c that engage with the lower engagement projections 2e to hold the cap body 6 against the mounting body 2.

[0022] The cylindrical body 7 is formed into a cylindrical shape with the axis O as the center line, and is provided inside the outer peripheral wall 6b and outside the upper cylindrical portion 2f of the mounting body 2. The cylindrical body 7 is provided rotatably with respect to the upper cylindrical portion 2f. The outer peripheral surface of the cylindrical body 7 and the inner peripheral surface of the outer peripheral wall 6b are provided with vertical grooves that extend in the vertical direction and engage with each other, and the cylindrical body 7 is attached to the cap body 6 in a non-rotatable manner. The inner peripheral surface of the cylindrical body 7 is provided with a second screw portion 7a formed in a female screw shape. In this embodiment, the second screw portion 7a is provided as a double-threaded screw, but may be a screw with three or more threads or a single-threaded screw. As shown in the figure, the pitch of the second screw portion 7a is larger than the pitch of the first screw portion 2d in a female screw shape provided on the mounting body 2.

[0023] The shaft body 8 is cylindrical, extends along the axis O, and is inserted into the insertion hole 2c of the attachment body 2. In this state, the seal member 4 is also inserted into the shaft body 8. The seal member 4 is slidable against the outer circumferential surface of the shaft body 8 and is in liquid-tight contact with the outer circumferential surface of the shaft body 8, preventing the content liquid in the storage space S from leaking along the outer circumferential surface of the shaft body 8.

[0024] 1, an applicator 9 is attached to the lower end of the shaft body 8, located near the bottom 1a of the container body 1, with the first screw portion 2d screwed into the mouth screw portion 1d of the attachment body 2. The applicator 9 is used to apply the content liquid, and is formed, for example, in a brush-like, paintbrush-like or brush-like shape depending on the type of content liquid, the destination to be applied, etc.

[0025] A pair of projections 8a projecting radially outward is provided at the upper end of the shaft body 8. As shown in the AA cross section in Fig. 1, the pair of projections 8a is threadedly engaged with the respective thread grooves of the second threaded portion 7a, which is a double-start thread, via a pair of grooves 2g provided in the upper cylindrical portion 2f.

[0026] In the application container 100 having such a configuration, when applying the content liquid, as shown in FIG. 2, the cap body 6 is rotated relative to the container body 1. Here, since the outer peripheral wall 6b of the cap body 6 can rotate relative to the outer peripheral wall 2b of the attachment body 2, the cap body 6 can be rotated leaving the attachment body 2 attached to the container body 1. Here, the cylindrical body 7 provided inside the cap body 6 is attached to the cap body 6 in a manner that does not allow it to rotate, so the cylindrical body 7 also rotates together with the cap body 6. In addition, the protrusion 8a of the shaft body 8 arranged inside the cylindrical body 7 is accommodated in the groove portion 2g extending in the vertical direction and is also screwed into the second screw portion 7a. Therefore, when the cylindrical body 7 rotates together with the cap body 6, the protrusion 8a of the shaft body 8 is guided by the second screw portion 7a and rises along the groove portion 2g. Then, when the rotation of the cap body 6 continues, the upper end of the shaft body 8 presses against the top wall 6a of the cap body 6 as shown in FIG. 2.

[0027] The shaft body 8, which has been pressed against the top wall 6a of the cap body 6, cannot rise any further and therefore rotates together with the cap body 6. Here, the protrusion 8a on the shaft body 8 is fitted into the groove 2g of the attachment body 2, so when the shaft body 8 rotates together with the cap body 6, the attachment body 2 also rotates together. Therefore, as shown in FIG. 3, the first screw portion 2d of the attachment body 2 and the mouth screw portion 1d of the container body 1 are released from the screw engagement, and the cap body 6 and the like can be removed from the container body 1 together with the attachment body 2.

[0028] 4, when the cap body 6 etc. are removed from the container body 1, the upper end of the shaft 8 has moved toward the top wall 6a of the cap body 6, and the applicator 9 is in a position close to the cap body 6. In other words, the applicator 9 is located close to the fingers holding the cap body 6, making it easier to apply the content liquid.

[0029] In addition, when the resistance acting between the container body 1 and the attachment body 2 is small, when the cap body 6 is rotated relative to the container body 1, the screw engagement between the first screw portion 2d and the mouth screw portion 1d may loosen before the shaft body 8 rises, and the attachment body 2 may come off the container body 1. However, in this embodiment, the resistance acting on the cylindrical body 7 and the shaft body 8 is made smaller than the resistance acting between the container body 1 and the attachment body 2, so that the shaft body 8 can be raised preferentially as described above. In this embodiment, the pitch of the second screw portion 7a is larger than the pitch of the first screw portion 2d, so that the resistance acting between the second screw portion 7a and the protrusion 8a is smaller than the resistance generated between the first screw portion 2d and the mouth screw portion 1d. Therefore, the action of raising the shaft body 8 preferentially is more reliable. In addition, since the pitch of the second screw portion 7a is larger than the pitch of the first screw portion 2d, the shaft body 8 rises more quickly compared to the speed at which the attachment body 2 rises relative to the container body 1. Therefore, when removed from the container body 1, the state in which the applicator 9 is located close to the cap body 6 as shown in FIG. 4 can be more reliably achieved.

[0030] Various modifications can be made to the above-mentioned application container 100. For example, the cap body 6 and the cylindrical body 7 in this embodiment are made as separate members in consideration of the configuration of the mold, etc., but they can also be integrally formed depending on the shape, etc. Also, although the mouth thread portion 1d is formed as a male thread and the first thread portion 2d is formed as a female thread, the relationship between the male thread and the female thread may be reversed.

[0031] The applicator container according to the present invention can be realized in another embodiment. Fig. 5 to Fig. 8 are diagrams showing a second embodiment of the applicator container according to the present invention. The applicator container 100A of this embodiment is basically configured similarly to the applicator container 100 described above, but includes an attachment body 2A and a cap body 6A instead of the attachment body 2 and the cap body 6.

[0032] The mounting body 2A has a top wall 2a having the same configuration as the mounting body 2 described above. The outer edge of the top wall 2a is provided with a stepped outer peripheral wall 2h that extends downward, then extends horizontally to expand in diameter, and further extends downward. The top wall 2a is provided with an insertion hole 2c similar to that of the mounting body 2 described above, and a first threaded portion 2d is provided on the inner peripheral surface of the outer peripheral wall 2h. In addition, an upper engagement protrusion 2j that protrudes radially outward is provided on the outer peripheral surface of the portion where the top wall 2a and the outer peripheral wall 2h are connected.

[0033] The cap body 6A includes a top wall 6a similar to the cap body 6 described above, and an outer peripheral wall 6d extending downward from the outer edge of the top wall 6a and above the outer peripheral wall 2h. As shown in Fig. 5, the outer peripheral wall 2h and the outer peripheral wall 6d are arranged in series and are both exposed to the outside. An inward claw portion 6e is provided at the lower end of the inner peripheral surface of the outer peripheral wall 6d to engage with the upper engagement protrusion 2j and hold the cap body 6A against the mounting body 2A.

[0034] When applying the content liquid, the cap body 6A is rotated with respect to the container body 1 in the application container 100A of this embodiment as well, as shown in Fig. 6. As a result, the cylindrical body 7 rotates together with the cap body 6A, and the shaft body 8, whose projection 8a is screwed into the second screw portion 7a, rises with respect to the cap body 6A. When the rotation of the cap body 6A continues, the upper end of the shaft body 8 presses against the top wall 6a of the cap body 6A as shown in Fig. 6 and stops rising, and then the attachment body 2A rotates together with the cap body 6A due to the projection 8a that fits into the groove portion 2g, and the screwing between the first screw portion 2d and the mouth screw portion 1d is released, and the cap body 6A and the like can be removed from the container body 1.

[0035] When the cap body 6A is removed from the container body 1, the shaft 8 has moved toward the cap body 6A as shown in Fig. 8(a), and the applicator 9 is located close to the cap body 6A. That is, in this embodiment as well, the applicator 9 is located close to the fingers holding the cap body 6A, making it easier to apply the content liquid.

[0036] In addition, since the outer peripheral wall 2h of the attachment body 2A in this embodiment is exposed to the outside, for example, by holding the outer peripheral wall 2h with one hand and pinching the outer peripheral wall 6d of the cap body 6A with the other hand, the cap body 6A can be rotated relative to the attachment body 2A as shown in Fig. 8(b). This allows the shaft 8 to move forward and backward relative to the cap body 6A, so the position of the applicator 9 can be changed according to the user's preference.

[0037] Although one embodiment of the present invention has been described above, the present invention is not limited to such a 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.
