Description

  The present invention relates to a container with an applicator, particularly a container with an applicator that contains a liquid with high viscosity and low fluidity, and the bottle container is swung with respect to the bottle container with the cap closed. The present invention relates to an applicator-equipped container in which the remaining content is adhered to the applicator to reduce the remaining amount.

  Conventionally, in containers filled with liquids such as mascara and gloss with high viscosity and low fluidity, stick-like coating is applied to the cap so that the high-viscosity contents can be taken out and applied directly to the desired location. A so-called container with an applicator provided with a tool is used. Even if the container with the applicator is used and the content decreases and the liquid level is lowered, the liquid with high viscosity remains less adhered to the inner wall surface of the container because the fluidity is low. There is a disadvantage that it cannot be adhered to the water and must be disposed of with many contents remaining.

  Therefore, in order to reduce the remaining contents, for example, Japanese Patent Laid-Open No. 2001-327327 (Patent Document 1) discloses a bottomed cylindrical container body having a mouth portion and a body wall portion, and a container. In a container with an applicator provided with a cap provided with an applicator extending into the body, at least a part of the bottle container is formed so as to be elastically deformable, and the container main body is elastically deformed. The structure which provides the movable area | region of an applicator and adheres the remaining content to an applicator is disclosed. In such a structure, it is possible to reduce the remaining contents, but since the elastic deformation portion is formed in the bottle container, it cannot have a beautiful appearance, and depending on the fatigue of the elastic deformation portion. There is a problem that the deformed portion is damaged and the contents leak out.

  JP-A-4-22302 (Patent Document 2) discloses that the brush inserted into the bottle container is eccentric from the center of the bottle so that when the brush is rotated with respect to the bottle container, the brush adheres to the peripheral wall of the bottle container. A structure is disclosed that allows the remaining contents to adhere to the brush. However, this structure has the disadvantages that the cap mounting structure is complicated and the number of parts is increased in order to allow the brush to move along the inner wall surface of the bottle container.

  A preferred embodiment of the present invention will be described in detail below. The present invention relates to an applicator comprising a bottomed cylindrical bottle container having a mouth portion and a body wall portion, and a cap having an application shaft extending from the mouth portion of the bottle container into the bottle container. In the attached container, a spherical bulge is formed on the outer peripheral surface of the mouth of the bottle container, the inner wall of the cap is connected to the spherical bulge in a ball joint shape, and the cap is attached to the bottle container while the cap is inserted. The movable region of the applicator can be enlarged with respect to the bottle container while the cap is inserted, so that the applicator can come into contact with the inner bottom portion of the bottle container. .

  Regarding the ball joint structure that constitutes the connection between the bottle container and the cap, two ribs protruding inwardly are arranged on the inner wall surface near the cap opening end with a gap between them. The spherical bulge is engaged. The two ribs are formed such that at least one of the ribs is formed by one annular protrusion that surrounds the inner wall surface of the cap, and the other rib is formed by a plurality of protrusions. The two ribs may be annular ribs surrounding the inner wall surface of the cap, and the two ribs may be composed of a plurality of protrusions. Furthermore, an arc surface is provided at the mouth opening end of the bottle container, and an arc-shaped and annular packing is attached to the inside of the cap so as to follow the arc surface of the mouth of the bottle container. It is preferable that the inside of the bottle container is kept airtight regardless of the rocking of the cap by the close contact with the packing.

  As for the ball joint structure that constitutes the connection between the bottle container and the cap, a rib projecting inward is formed on the inner wall surface near the cap opening end to engage with the lower surface side of the spherical bulge portion. Let's make it. In addition, an arc surface is provided on the upper surface of the ironing member attached to the mouth opening end of the bottle container, and a concave arc surface that closely adheres to the arc surface of the ironing member is formed at the base of the applicator provided in the cap. Thus, the inside of the bottle container may be kept airtight regardless of the swing of the cap by connecting as a ball joint state composed of the rib, the spherical bulging portion, the concave arc surface, and the convex arc surface. . Furthermore, a rib is also formed on the outer surface near the cap opening end, and a slide cap is inserted into the outer periphery of the cap so that the rib formed on the outer surface of the cap is pressed according to the sliding state of the slide cap. May be in close contact with the bottle container.

  Referring to FIG. 1, (1) is a container with an applicator, a bottle container (2) with a squeezing member (5) inserted in the mouth, and a cap (3) connected with an application shaft (4). Consists of. A spherical bulge (2a) is formed near the mouth of the bottle container (2), and the upper end of the ironing member (5) inserted into the mouth is formed on an arc surface (5a). Has been. The cap (3) has a cylindrical shape with one end opened, and an application shaft (4) having an application tool (4a) at the tip is fitted inside. At the base of the coating shaft (4), the cross section has an arc shape and an annular packing (6) is inserted. A circumferential lower rib (3a) is formed on the inner wall in the vicinity of the cap opening end so as to protrude toward the inside of the cap, and at a position above the cap from the lower rib (3a). Is formed with a plurality of upper ribs (3b) protruding toward the inside of the cap (see FIG. 2). It is preferable that about 3 to 5 upper ribs (3b) are formed on the inner peripheral surface of the cap. However, the upper rib (3b) is not particularly limited to this and is an annular rib like the lower rib (3a). It doesn't matter. Of course, the lower rib (3a) may be formed as a plurality of protruding ribs.

  When the cap (3) is inserted into the bottle container (2), the bottle container (2) and the cap (3) are connected to each other by an annular bulge formed in the vicinity of the mouth of the bottle container (2) ( 2a) is performed by holding the lower rib (3a) and the upper rib (3b) formed on the inner wall of the cap (3). That is, when the cap (3) is inserted from the mouth side of the bottle container (2), the lower rib (3a) formed on the inner wall of the cap (3) gets over the spherical bulging portion (2a) and the spherical bulging portion ( 2a) The lower spherical part is reached. At the same time, the upper rib (3b) is in contact with the upper spherical surface of the spherical bulge (2a), and as a result, the spherical bulge (2a) is located between the lower rib (3a) and the upper rib (3b). The movement of the spherical bulge part (2a) is restrained between the upper and lower ribs (3a) (3b), and it is connected as a ball joint state consisting of the upper and lower ribs (3a) (3b) and the spherical bulge part (2a). To do.

  The packing (6) inserted at the base of the coating shaft (4) has an arcuate cross section as described above. The curvature of the arc surface is the same as the curvature of the arc surface (5a) formed at the upper end of the ironing member (5), and the width of the arc surface of the packing (6) is the arc surface of the ironing member (5). It is set longer than the width of (5a). As a result, even if the packing (6) slides on the arc surface (5a) by the swinging action described later, the packing (6) always contacts the arc surface (5a). As long as 3) is inserted, the inside of the bottle container (2) can be hermetically sealed regardless of any swinging motion.

  Next, an operation of swinging the cap (3) with respect to the bottle container (2) (inclined in one direction in the illustrated example) in a state of being attached to the bottle container (2) will be described. FIG. 3 shows a state in which the cap (3) is pushed in the direction of the arrow and tilted with respect to the bottle container (2). By pushing the cap (3) in a desired direction, the lower rib (3a) and the upper rib (3b) are slid while contacting the surface of the spherical bulge (2a). With the joint structure as a fulcrum, the cap (3) can be tilted with respect to the bottle container (2). At this time, the coating shaft (4) fitted to the cap (3) tilts in the direction opposite to the tilting direction of the cap in the bottle container (2), and the cap (3) is still inserted. The applicator (4a) can reach the inner wall surface of the bottle container (2). Thereby, the contents adhering to the inner wall surface of the bottle container (2) can be attached to the applicator (4a). Even in this tilted state, as described above, the arcuate surface (5a) of the ironing member (5) and the packing (6) are always in surface contact. It is kept.

  As described above, since the bottle container (2) and the cap (3) are connected in a ball joint shape, there is no restriction on the swinging direction of the cap (3). That is, it is possible to incline to the angle at which the applicator contacts the inner wall surface of the bottle container (2) and to rotate 360 degrees in the horizontal direction. Thereby, the application shaft (4) can be swung and rotated in the bottle container (2), and the application tool (4a) can wipe the inner wall surface below the bottle container (2) over the entire circumference. . Therefore, the high-viscosity and low-fluid content can be efficiently attached to the applicator (4a), and the remaining content can be reduced.

  Referring to FIG. 4, (10) is a container with an applicator according to another embodiment, in which a bottle container (11) in which a squeezing member (14) is inserted into the mouth and an application shaft (13) are connected. It consists of a cap (12). A spherical bulge portion (11a) is formed in the vicinity of the mouth of the bottle container (11), and the upper end of the ironing member (14) inserted into the mouth is on the convex arc surface (14a). Is formed. The cap (12) has a cylindrical shape with one open end, and an application shaft (13) having an application tool (13a) at the tip is fitted inside. An arc surface (13b) having a circular cross section is formed at the base of the coating shaft (13). A circumferential rib (12a) is formed on the inner wall in the vicinity of the cap opening end so as to protrude toward the inside of the cap. The ribs (12a) are not particularly limited, as in the first embodiment, such as being formed in an annular shape or about 3 to 5 on the inner peripheral surface.

  The connection between the bottle container (11) and the cap (12) is a spherical bulge formed in the vicinity of the mouth of the bottle container (11) when the cap (12) is inserted into the bottle container (11). The lower peripheral surface of 11a) is surrounded by a rib (12a) formed on the inner wall of the cap (12). That is, when the cap (12) is inserted from the mouth side of the bottle container (11), the rib (12a) formed on the inner wall of the cap (12) gets over the spherical bulge portion (11a) and the spherical bulge portion (11a ) Reaches the lower spherical surface, and the spherical bulge is held by the rib. At the same time, the concave arc surface (13b) is attracted to the convex arc surface (14a) and comes into surface contact so as to press the convex arc surface, and the rib (12a), the spherical bulge portion (11a), and the concave arc surface ( 13b) and a ball joint state composed of the convex arc surface (14a).

  The curvature of the concave arc surface (13b), the convex arc surface (14a), and the surface of the spherical bulge portion (11a) are aligned so as to be located on the same circumference. As a result, even if the concave arc surface (13b) slides on the convex arc surface (14a) by the swinging motion, the rib (12a) of the cap (12) always abuts on the lower surface side of the spherical bulge portion (11). At the same time, since the concave arc surface (13b) is kept in surface contact with the convex arc surface (14a), as long as the cap (12) is inserted into the bottle container (11), no matter what swinging motion is performed, (11) can be kept airtight. Since the positional relationship between the bottle (11) and the applicator (13) by the swinging operation is basically the same as that of the first embodiment, detailed description is omitted.

  5-8 shows the other Example of a container with an applicator. 5 shows a state where the bottle and the cap are connected and fixed, FIG. 6 is a conceptual view of the cap opening end, FIG. 7 shows a state where the slide cap is released, and FIG. 8 shows a state where the cap is swung with respect to the bottle container. It is. Referring to FIG. 5, (20) is a container with an applicator according to another embodiment, and connects the bottle container (21) with the ironing member (25) inserted into the mouth and the application shaft (24). And the cap (22). (23) is a cylindrical slide cap that is slidably attached to the outer periphery of the cap (22). When the slide cap (23) is slid toward the bottle (21) with the bottle (21) and the cap (22) connected, the slide cap (23) comes into contact with a bottle shoulder (21b) described later, and the cap (22) This prevents the bottle (21) from swinging.

  As in the second embodiment, a spherical bulging portion (21a) is formed in the vicinity of the mouth portion of the bottle container (21), and an ironing member (25) having an upper end formed on a convex arc surface (25a). Is inserted. The cap (22) has a cylindrical shape with one end open, and an application shaft (24) having an application tool (24a) at the tip is fitted inside. The root of the coating shaft (24) has a circular arc cross section, and a concave arc surface (24b) having the same curvature as the surface curvature of the ironing member (25) is formed. An inner engagement rib (22a) is formed on the inner surface near the opening end of the cap (22), and an outer engagement rib (22a) is formed on the outer surface near the opening end from the inner engagement rib (22a). 22b) is formed. The structure in the vicinity of the opening end of the cap (22) is preferably a shape provided with a plurality of slits as shown in FIG. 7, but is not particularly limited thereto. The surface curvature of the spherical bulge (21a), the curvature of the concave arc surface (24b) and the convex arc surface (25a) are the same, and when the cap (22) and the bottle (21) are connected, the bottle (21) The cap (22) swings smoothly.

  When the cap (22) is inserted into the bottle container (21), the connection between the bottle container (21) and the cap (12) is a spherical bulge formed in the vicinity of the mouth of the bottle container (21) ( 21a) is held by an inner engagement rib (22a) formed in the vicinity of the opening end of the cap (22). That is, when the cap (22) is inserted from the mouth side of the bottle container (21), the inner engagement rib (22a) gets over the spherical bulge portion (21a) and the lower spherical surface portion of the spherical bulge portion (21a). And the bottle (21) and the cap (22) are connected to each other, and the inner engagement rib (22a), the spherical bulge portion (21a), the concave arc surface (24b), and the convex arc surface (25a) are formed. Connect as a joint state.

  The slide cap (23) inserted on the outer periphery of the cap (22) is for suppressing the swinging movement of the bottle container (21) and the cap (22), and the slide cap (23) is attached to the bottle container ( After inserting into 21), slide it toward the bottle container (21) side. The step (23a) formed on the inner peripheral surface presses the outer engaging rib (22b) toward the spherical bulge (21a) while the slide cap (23) surrounds the opening end of the cap (22) by sliding. To do. Along with this, the contact is strengthened so that the inner engagement rib (22a) wraps around below the spherical bulge portion (21a), and as a result, the concave arc surface (24b) becomes the convex arc surface (25a). While being attracted, the surface contact becomes stronger and the hermeticity of the bottle container (21) is further enhanced. Further, the lower end portion of the slide cap (23) is brought into contact with the shoulder portion (21b) of the bottle container (21), so that the swinging motion of the cap (22) is suppressed.

  The curvature of the concave arc surface (24b), the convex arc surface (25a), and the surface of the spherical bulge portion (21a) are aligned so as to be located on the same circumference. Thus, even if the concave arc surface (24b) slides on the convex arc surface (25a) by the swinging motion of the cap, the inner engagement rib (22a) of the cap (22) is Since the concave arc surface (24b) is kept in surface contact with the convex arc surface (25a), the rocking surface is always in contact with the lower surface side, so as long as the cap (22) is inserted in the bottle container (21) Even if this is done, the inside of the bottle container (21) can be kept airtight.

  The swinging operation with the cap (22) inserted into the bottle container (21) is basically the same as in the first and second embodiments, but the slide cap (23) as described above for this embodiment. Therefore, it is necessary to open it when swinging. When the slide cap (23) is slid toward the cap (22), the open end of the cap (22) is released from the pressure toward the spherical bulge portion (21a). As a result, the bottle container (21) and the cap (22) are loosely connected and can swing. For the subsequent swing operation, the inner engagement rib (22a), the spherical bulge portion (21a), and the concave arc surface (24b) are pushed by pushing the cap (22) in a desired direction as in the first and second embodiments. The cap (22) can be tilted with respect to the bottle container (21) with the ball joint structure formed of the convex arc surface (25a) as a fulcrum.
