Description

The present invention relates to a container with a coating tool.

Conventionally, as a container with a coating tool, a container body in which the content liquid is stored, a cap body detachably attached to the mouth of the container body, and an ironing cylinder member fitted in the mouth of the container body have been used. It is equipped with a rod-shaped coating tool that is attached to the cap body and inserted into the ironing cylinder member, and is tubular in the radial inward direction at the middle portion in the axial direction on the inner peripheral surface of the ironing cylinder member. A flange-shaped step portion in which a squeeze piece is projected and faces or abuts from below with respect to the lower end opening edge in the mouth portion, and a cylinder extending downward from the outer peripheral edge of the squeeze cylinder member. A configuration having a large-diameter portion having a shape is known. In this container with a coating tool, when the coating tool is taken out from the container body, excess liquid adhering to the outer periphery of the coating tool can be squeezed off by a squeezing piece.

However, in this container with a coating tool, the coating tool and the ironing cylinder member may be fixed to each other due to the solidification of the content liquid adhering to their surfaces. In this case, the force applied to the coating tool when the coating tool is pulled out from the container body is transmitted to the ironing cylinder member, so that the flange-shaped step portion is in close contact with the lower end opening edge of the mouth portion and the large diameter portion is contracted. The diameter was deformed, and there was a risk that the ironing cylinder member would be displaced upward with respect to the container body.

As a means for solving such a problem, for example, as shown in Patent Document 1, an elastic ring of a member different from the ironing cylinder member is fitted in a large diameter portion. This elastic ring increases the rigidity of the large-diameter portion against deformation inward in the radial direction, and prevents the ironing cylinder member from being displaced upward with respect to the container body.

However, in the conventional container with a coating tool, since the elastic ring is provided as a separate member from the ironing cylinder member, the elastic ring may fall off from the ironing cylinder member. Further, since the elastic ring is provided as a member separate from the ironing cylinder member, there is a problem that the number of parts increases and it takes time and effort to assemble the container with the coating tool.

The present invention has been made in view of the above circumstances, and when the coating tool is pulled out from the container body, the ironing cylinder member is prevented from being displaced upward with respect to the container body, and then the assembly is performed. It is an object of the present invention to provide a container with a coating tool that can be easily performed.

In order to solve the above problems, the present invention proposes the following means.
The container with a coating tool of the present invention includes a container body in which the content liquid is stored, a cap body detachably attached to the mouth portion of the container body, and an ironing cylinder member fitted in the mouth portion of the container body. A cylinder that is attached to the cap body and has a rod-shaped coating tool inserted into the ironing cylinder member, and is provided on the inner peripheral surface of the ironing cylinder member so as to project inward in the radial direction. A shaped iron piece is formed, and the outer peripheral surface of the ironing cylinder member projects outward in the radial direction and engages with the locked portion formed on the inner peripheral surface of the container body from below. engaging portion for engagement is formed, the inner circumferential surface of the ironing cylinder member, and at least one of the outer circumferential surface of said applicator is close to or abutting regulation portion is formed on the other, the applicator When the ironing cylinder member also moves upward and the engaging portion tries to be displaced inward in the radial direction when the container body is pulled out, the restricting portion comes into contact with the other. The displacement of the engaging portion is suppressed to regulate the reduced diameter deformation of the ironing cylinder member , a recessed portion is formed on the outer peripheral surface of the ironing cylinder member, and a thin portion is formed on the ironing cylinder member by the recessed portion. The ironing piece protrudes inward in the radial direction from the portion where the thin portion is located on the inner peripheral surface of the ironing cylinder member, and the regulating portion is located below the ironing piece. It is characterized by that.

According to the present invention, on at least one of the inner peripheral surface of the ironing cylinder member and the outer peripheral surface of the coating tool, a regulating portion for restricting the diameter-reduced deformation of the ironing cylinder member is formed. When the ironing cylinder member also moves upward and the engaging portion tries to displace inward in the radial direction when it is pulled out from the main body, the regulating portion abuts on the other to suppress the displacement of the engaging portion. be able to. As a result, the engagement of the engaging portion with the locked portion is maintained, and it is possible to prevent the ironing cylinder member from being displaced upward with respect to the container body.
Moreover, since the regulating portion is formed on at least one of the ironing cylinder member and the coating tool, it is possible to regulate the diameter reduction deformation of the ironing cylinder member without increasing the number of parts.
Therefore, when the coating tool is taken out from the container body, the ironing cylinder member can be easily assembled while being suppressed from being displaced upward with respect to the container body.

Further, in the above-mentioned container with a coating tool, it is desirable that at least a part of the restricting portion is located at the same position in the vertical direction as the engaging portion.

According to the present invention, since at least a part of the regulating portion overlaps with the engaging portion in the radial direction, when the engaging portion tries to be displaced inward in the radial direction when the coating tool is pulled out from the container body. In addition, the regulating portion formed on at least one of the inner peripheral surface of the ironing cylinder member and the outer peripheral surface of the coating tool can be immediately brought into contact with the other. Further, since at least a part of the regulating portion overlaps the engaging portion in the radial direction, the regulation portion is regulated as compared with the case where the regulating portion does not overlap the engaging portion in the radial direction (when separated in the vertical direction). It is possible to prevent the portion of the ironing cylinder member where the engaging portion is located from being reduced in diameter and deformed in a state where the portion is in contact with the other. Therefore, the displacement of the engaging portion inward in the radial direction can be reliably regulated. Therefore, when the coating tool is pulled out from the container body, it is possible to more reliably prevent the ironing cylinder member from being displaced upward with respect to the container body.

According to the present invention, when the coating tool is taken out from the container body, the container with the coating tool can be easily assembled while suppressing the ironing cylinder member from being displaced upward with respect to the container body. Can be provided.

The upper portion of the regulation rib 30 gradually extends outward in the radial direction from the tip portion 30a toward the upper side.

Hereinafter, the operation of the container 1 with a coating tool of the present embodiment will be described.
First, a case where the coating tool 6 is taken out from the container body 2 will be described.
When the applicator 6 is pulled out from the container body 2, the cap body 4 is first rotated with respect to the container body 2, the screw between the cap body 4 and the container body 2 is released, and the cap body 4 is moved to the container body 2. Pull up against. In this way, the coating tool 6 attached to the cap body 4 is moved upward with respect to the container body 2.

Here, the lower end edge of the large diameter portion 16 of the coating tool 6 and the upper surface of the flange portion 27 of the ironing cylinder member 5 are fixed to each other by solidifying the content liquid adhering to the container 1 with the coating tool during the previous use. May be. In this case, when the cap body 4 is pulled upward with respect to the container body 2, the force applied to the coating tool 6 causes the large diameter portion 16 of the coating tool 6 and the portion where the ironing cylinder member 5 is fixed to the flange portion 27. It is transmitted to the ironing cylinder member 5 through the ironing cylinder member 5. Then, the ironing cylinder member 5 also moves upward, and the engaging portion 29 comes into contact with the locked portion 8. Since the locked portion 8 is gradually reduced in diameter as it goes upward, when the ironing cylinder member 5 moves upward, the engaging portion 29 comes into close contact with the locked portion 8 and faces inward in the radial direction. Try to displace. As a result, the lower end portion of the fitting cylinder portion 26 where the engaging portion 29 is located tends to be reduced in diameter.

At this time, the regulation rib 30 provided on the inner peripheral surface of the fitting cylinder portion 26 comes into contact with the outer peripheral surface (second bulging portion 22) of the coating tool 6 so as to be inside the engaging portion 29 in the radial direction. The displacement toward is suppressed, and the reduced diameter deformation of the ironing cylinder member 5 is regulated. Further, the second bulging portion 22 provided on the outer peripheral surface of the coating tool 6 comes into contact with the inner peripheral surface (regulating rib 30) of the fitting cylinder portion 26, thereby inward in the radial direction of the engaging portion 29. It suppresses the displacement toward and regulates the diameter reduction deformation of the ironing cylinder member 5. As a result, the engagement of the engaging portion 29 with the locked portion 8 is maintained, and it is possible to prevent the ironing cylinder member 5 from being displaced upward with respect to the container body 2.

When the applicator 6 is further moved upward so as to be pulled out from the container body 2, the upper portion of the second bulging portion 22 of the applicator 6 comes into contact with the tip end portion of the ironing piece 28. After that, when the coating tool 6 is further moved upward, the tip portion of the ironing piece 28 is elastically deformed so as to be turned upward. That is, the coating tool 6 is moved upward in a state where the tip end portion of the ironing piece 28 is in contact with the portion located below the recessed portion 23 on the outer peripheral surface thereof. As a result, the excess liquid adhering to the outer peripheral surface of the coating tool 6 can be squeezed off.

Next, a case where the applicator 6 is inserted into the container body 2 will be described.
When the applicator 6 is inserted into the container body 2, the applicator 17 provided at the lower end of the applicator 6 is inserted into the mouth 3, and then the cap body 4 is moved downward to the applicator 6. Is pushed into the container body 2. Then, the first bulging portion 21 of the coating tool 6 is inserted through the upper end opening of the ironing cylinder member 5.

Next, the cap body 4 is rotated with respect to the container body 2, and the cap body 4 is moved further downward while screwing the cap body 4 to the container body 2. Here, the outer diameter of the outermost peripheral portion of the first bulging portion 21 is the same as the inner diameter of the intermediate portion 26a of the fitting cylinder portion 26 of the ironing cylinder member 5. Therefore, the first bulging portion 21 slides with respect to the inner peripheral surface of the fitting cylinder portion 26, and moves downward while collecting the content liquid adhering to the inner peripheral surface of the fitting cylinder portion 26. To do.

When the attachment of the cap body 4 to the container body 2 is completed, the lower portion 21b of the first bulging portion 21 is in contact with or in close contact with the upper surface 28a of the ironing piece 28 from above. For this reason, the content liquid that has been scraped up as the first bulging portion 21 moves downward flows into the container body 2 from between the first bulging portion 21 and the ironing piece 28 through the groove portion 19. Be returned. In this way, the first bulging portion 21 can return the content liquid adhering to the inner peripheral surface of the fitting cylinder portion 26 into the container body 2.

As described in detail above, the container 1 with the coating tool of the present embodiment suppresses the ironing cylinder member 5 from being displaced upward with respect to the container body 2 when the coating tool 6 is pulled out from the container body 2. it can.
Further, since the regulating rib 30 is formed on the ironing cylinder member 5 and the second bulging portion 22 is formed on the coating tool 6, the reduced diameter deformation of the ironing cylinder member 5 is regulated without increasing the number of parts. can do. Therefore, it is possible to provide a container 1 with a coating tool that can be easily assembled.

Moreover, the regulation rib 30 and the second bulging portion 22 overlap with the engaging portion 29 in the radial direction. Therefore, when the coating tool 6 is pulled out from the container body 2, when the engaging portion 29 tries to be displaced inward in the radial direction, the regulation rib 30 and the second bulging portion 22 are immediately brought into contact with each other. Can be made to.
Further, since the regulation rib 30 and the second bulging portion 22 are radially overlapped with the engaging portion 29, the regulating rib 30 and the second bulging portion 22 are not overlapped with the engaging portion in the radial direction. 2 It is possible to prevent the lower end portion of the fitting cylinder portion 26 where the engaging portion 29 is located from the ironing cylinder member 5 from being reduced in diameter and deformed while the bulging portion 22 is in contact with the bulging portion 22.
Therefore, the displacement of the engaging portion 29 inward in the radial direction can be reliably regulated, and when the coating tool 6 is pulled out from the container body 2, the ironing cylinder member 5 is displaced upward with respect to the container body 2. Can be suppressed.

[Second Embodiment]
Next, the container 101 with a coating tool according to the second embodiment will be described.

The bulging portion 122 is formed at a position overlapping the lower end portion of the mouth portion 3 in the container axis O direction. The bulging portion 122 is provided close to the inner peripheral surface of the ironing cylinder member 105. The bulging portion 122 regulates the reduced diameter deformation of the ironing cylinder member 105.
The reduced diameter portion 124 extends straight upward from the upper end edge of the bulging portion 122.

The sliding cylinder member 112 is extrapolated to the reduced diameter portion 124. The sliding cylinder member 112 extends straight downward from the upper end edge, and then gradually increases in diameter at the lower end 112a toward the lower end. The outer diameter of the lower end edge of the sliding cylinder member 112 is larger than the outer diameter of the bulging portion 122 of the main body portion 111. The dimension of the sliding cylinder member 112 in the container shaft O direction is set to be equal to or slightly smaller than the dimension of the reduced diameter portion 124 in the container shaft O direction, and the sliding cylinder member 112 has the container shaft with respect to the reduced diameter portion 124. It regulates displacement in the O direction.

The ironing cylinder member 105 has a fitting cylinder portion 126, a flange portion 27, an ironing piece 28, a plurality of engaging portions 129, and a plurality of regulating ribs 30.
The inner peripheral surface of the upper portion 126a of the fitting cylinder portion 126 located above the ironing piece 28 is equivalent to the outer diameter of the lower end edge of the sliding cylinder member 112 from the outer peripheral edge portion of the ironing piece 28 upward. It extends with the inner diameter of. Further, the inner peripheral surface of the lower portion 126b of the fitting cylinder portion 126 located below the ironing piece 28 has an outer diameter of the lower end edge of the sliding cylinder member 112 downward from the outer peripheral edge portion of the ironing piece 28. It extends with a larger inner diameter.

The tip of the ironing piece 28 is arranged close to the outer peripheral surface of the sliding cylinder member 112 in the intermediate portion in the container axis O direction. The inner diameter of the ironing piece 28 is smaller than the outer diameter of the lower portion 118a located below the bulging portion 122 of the connecting portion 118 of the coating tool 106.

As shown in FIG. 5, a plurality of engaging portions 129 (4 in the present embodiment) are formed at intervals in the circumferential direction. The engaging portion 129 is formed on the outer peripheral surface at the lower end portion of the fitting cylinder portion 126, and projects outward in the radial direction. When viewed from the container shaft O direction, both side surfaces of the engaging portion 129 facing both sides in the circumferential direction are formed so as to be parallel to each other. Further, the surface of the engaging portion 129 facing outward in the radial direction when viewed from the container shaft O direction is formed in an arc shape centered on the container shaft O. Each engaging portion 129 is arranged so as to overlap at least a part of the regulating rib 30 in the circumferential direction. As shown in FIG. 4, the engaging portion 129 overlaps the regulation rib 30 in the radial direction. The outer edge portion at the upper end of the engaging portion 129 is close to the inner peripheral surface 3a at the lower end portion of the mouth portion 3. The engaging portion 129 engages with the locked portion 8 formed on the inner peripheral surface of the container body 2 from below.

Hereinafter, the operation of the container 101 with a coating tool of the present embodiment will be described.
First, a case where the applicator 106 is taken out from the container body 2 will be described.
When the coating tool 106 is taken out from the container body 2, the cap body 4 is first rotated with respect to the container body 2 and the coating material attached to the cap body 4 is applied, as in the case of the container 1 with the coating tool in the first embodiment. The tool 106 is moved upward.

When the ironing cylinder member 105 moves upward together with the coating tool 106 due to the adhesion between the large diameter portion 16 of the coating tool 106 and the flange portion 27 of the ironing cylinder member 105, the plurality of engaging portions 129 hit the locked portion 8. It will be in contact. Since the locked portion 8 gradually shrinks in diameter as it goes upward, when the ironing cylinder member 105 moves upward, the plurality of engaging portions 129 come into close contact with the locked portion 8 and inward in the radial direction. Try to displace towards. As a result, the lower end portion of the fitting cylinder portion 126 where the engaging portion 129 is located tends to be reduced in diameter.

At this time, the regulation rib 30 provided on the inner peripheral surface of the fitting cylinder portion 126 abuts on the outer peripheral surface (bulging portion 122) of the applicator 106, so that the engaging portion 129 is directed inward in the radial direction. It suppresses the displacement and regulates the reduced diameter deformation of the ironing cylinder member 105. At this time, since each engaging portion 129 is arranged so as to overlap at least a part of the regulating rib 30 in the circumferential direction, the regulating rib 30 reliably regulates the displacement of each engaging portion 129 from the inside in the radial direction. it can. Further, the bulging portion 122 provided on the outer peripheral surface of the coating tool 106 is brought into contact with the inner peripheral surface (regulating rib 30) of the fitting cylinder portion 126 so as to be directed inward in the radial direction of the engaging portion 129. The displacement is suppressed, and the reduced diameter deformation of the ironing cylinder member 5 is regulated. As a result, the engagement of the engaging portion 129 with the locked portion 8 is maintained, and it is possible to prevent the ironing cylinder member 105 from being displaced upward with respect to the container body 2.

Even when a plurality of engaging portions 129 are intermittently formed along the circumferential direction in this way, the container 101 with a coating tool has the same function and effect as the container 1 with a coating tool in the first embodiment. Can be successful.

Next, a case where the applicator 106 is inserted into the container body 2 will be described.
