BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings for understanding of the present invention. It should be noted that the following embodiment is an example that embodies the present invention, and is not intended to limit the technical scope of the present invention.

A capping type container 1 according to the present invention basically comprises a container body 10 and a cap 20 as shown in FIGS. 1A, 1B, 2A and 2B. The container body 10 has a mouth portion 11 . The cylindrical portion 21 of the cap 20 can be attached to the mouth portion 11 by plugging.

Moreover, the container body 10 further includes a flange 12 , a mouth-side engaging convex portion 13 , and a slope portion 14 . Also, the cap 20 has a cap-side engaging protrusion 22 .

Further, the flange 12 is annularly bulged along the circumferential direction of the mouth portion 11 at a predetermined position on the outer peripheral surface of the mouth portion 11 .

In addition, the mouth-side engaging projection 13 is positioned at a predetermined position on the outer peripheral surface of the mouth 11 and above the position of the flange 12, and extends along the circumferential direction of the mouth 11 at a predetermined position. is bulging out with a length of

Here, in FIGS. 1A, 1B, 2A, 2B, and 3, the length d1 of the mouth-side engaging projection 13 is about a third of the total length d0 of the mouth 11 in the circumferential direction. With a length of 1, two mouth-side engaging projections 13 are provided, and the two mouth-side engaging projections 13 are provided at positions facing each other in the mouth 11. . 3, the two mouth-side engaging protrusions 13 are provided with a predetermined first interval d2 in the circumferential direction of the mouth 11. As shown in FIG.

Further, the slope portion 14 is provided from the upper end portion 12a of the flange 12 to one longitudinal end portion 13a of the mouth side engaging projection 13, and the slope portion 14 is inclined as the distance from the upper end portion 12a of the flange 12 increases. 13 has an inclined surface 14a inclined upward toward one longitudinal end portion 13a.

Also, the cap-side engaging convex portion 22 bulges for a predetermined length along the circumferential direction of the cylindrical portion 21 at a predetermined position below the inner peripheral surface of the cylindrical portion 21, When the plug 21 is plugged into the mouth portion 11 , it is locked between the flange 12 of the mouth portion 11 and the mouth-side engagement protrusion 13 .

Here, in FIGS. 1A, 1B, 2A, 2B, and 3, the length d3 of the cap-side engaging convex portion 22 is approximately one third of the total length d0 of the cylindrical portion 21 in the circumferential direction. Two cap-side engaging projections 22 are provided with a length of , and the two cap-side engaging projections 22 are provided at positions facing each other in the cylindrical portion 21 . The circumferential total length d0 of the cylindrical portion 21 corresponds to the circumferential total length d0 of the mouth portion 11 . Also, the length d3 of the cap-side engaging protrusion 22 is the same as the length d1 of the mouth-side engaging protrusion 13 . As shown in FIG. 3 , the two cap-side engaging projections 22 are provided with a predetermined second interval d4 in the circumferential direction of the mouth portion 11 . Here, the second spacing d4 is equivalent to the first spacing d2. Also, the shape of the cap-side engaging projection 22 is configured to be the same as the shape of the mouth - side engaging projection 13 .

As a result, even if the cap 20 is plugged into the mouth portion 11 , it can be easily removed without worrying about the position of the cap 20 with respect to the mouth portion 11 .

That is, when the user aligns the cylindrical portion 21 of the cap 20 with the mouth portion 11 of the container body 10 and pushes the cap 20 in, the cap-side engaging convex portion 22 of the cap 20 engages the mouth portion-side engaging convex portion of the mouth portion 11 . It climbs over the portion 13 and enters between the flange 12 of the mouth portion 11 and the mouth portion-side engaging projection portion 13 to be locked. Here, when the contact ring does not exist on the lower surface of the upper portion of the cap 20, the lower end portion 21a of the cylindrical portion 21 contacts the flange 12 of the mouth portion 11, and the cap 20 is attached to the mouth portion 11 while being stopped. This completes the plugging.

Here, for example, as shown in FIGS. 3, 5A, and 5B, the cap-side engaging convex portion 22 contacts the side surface of the slope portion 14 between the flange 12 and the mouth-side engaging convex portion 13. When they do not touch, that is, when the cap-side engaging protrusion 22 exists directly above the mouth-side engaging protrusion 13 and climbs over the mouth-side engaging protrusion 13 as it is, the outer circumference of the mouth 11 will come into contact with the surface.

In this state, as shown in FIGS. 3 and 6, the user moves the cap 20 from one longitudinal end 13a of the mouth-side engaging protrusion 13 to the other longitudinal direction of the mouth-side engaging protrusion 13. When rotated along the direction toward the end portion 13b, one end portion 22a in the longitudinal direction of the cap-side engaging protrusion 22 moves toward the inclined portion of the slope portion 14 as shown in FIGS. 3, 6, 7A, and 7B. It rides on the surface 14a, slides on the inclined surface 14a, and is guided to one longitudinal end 13a of the mouth-side engaging projection 13. As shown in FIG. Then, the cap-side engaging protrusion 22 rides on the mouth-side engaging protrusion 13 .

As a result, the user simply rotates the cap 20 in a predetermined direction, and the one longitudinal end 22a of the cap-side engaging projection 22 automatically slides on the inclined surface 14a of the slope portion 14. Since the cap-side engaging protrusion 22 rides on the mouth-side engaging protrusion 13, the cap 20 can be easily removed from the mouth 11. As shown in FIG.

By the way, when the capping was completed, as shown in FIGS. 8 and 9, the cap-side engaging convex portion 22 did not contact the side surface of the mouth portion 11 but the side surface of the slope portion 14. In other words, the cap-side engaging convex portion 22 does not exist directly above the mouth-side engaging convex portion 13, but exists deviated from the mouth-side engaging convex portion 13, straddling the slope portion 14, When the mouth-side engagement projection 13 is overcome, the cap-side engagement projection 22 enters the slope portion 14 between the flange 12 of the mouth 11 and the mouth-side engagement projection 13 and is locked. be. In this case, in FIGS. 8 and 9, a part of the cap-side engaging projection 22 contacts the side surface of the slope portion 14, and the other part of the cap-side engaging projection 22 contacts the outer peripheral surface of the mouth portion 11. ing.

In this state, as shown in FIGS. 8 and 9, the user moves the cap 20 from one longitudinal end 13a of the mouth-side engaging protrusion 13 to the longitudinal direction of the mouth-side engaging protrusion 13. When rotated along the direction toward the other end portion 13b, one longitudinal end portion 22a of the cap-side engaging projection 22 first moves along the side surface of the slope portion 14 in the circumferential direction of the mouth portion 11. , the cap-side engaging convex portion 22 abuts on the outer peripheral surface of the mouth portion 11 where the slope portion 14 is not present.

In this state, when the user continues to rotate the cap 20 again in the same direction, the cap-side engaging convex portion 22 descends from the side surface of the slope portion 14 and hits the outer peripheral surface of the mouth portion 11 this time. touch. Further, when one end 22a in the longitudinal direction of the cap-side engaging projection 22 moves to the front of the slope portion 14, it rides on the slope 14a of the slope portion 14 and slides on the slope 14a. Then, the cap-side engaging convex portion 22 rides on the mouth-side engaging convex portion 13 via the inclined surface 14 a of the slope portion 14 . That is, the cap 20 can be easily removed from the mouth portion 11 in the same manner as described above.

In this way, even when the cap-side engaging projection 22 abuts against the outer peripheral surface of the mouth portion 11 when the user plugs the cap 20, even if it abuts against the side surface of the slope portion 14, However, in any case, it can be easily removed.

Here, the types of mouth 11 and cap 20 are not particularly limited, and the present invention can be applied to any kind of mouth 11 and cap 20 .

The configuration of the flange 12 is not particularly limited as long as the flange 12 functions as a stopper and for positioning the cap 22 when the user plugs the cap 20 into the mouth portion 11 .

The number and configuration of the mouth-side engagement protrusions 13 are not particularly limited, and the number of the mouth-side engagement protrusions 13 is assumed to be two in FIGS. , the length d1 in the longitudinal direction (the circumferential length of the mouth portion 11) of the mouth-side engaging protrusion 13 is set to about one-third of the total length d0 in the circumferential direction of the mouth portion 11. , the number of the mouth-side engaging protrusions 13 may be one, three, or two or more, and the length d1 of the mouth-side engaging protrusions 13 in the longitudinal direction is 1/6 to 1/2 of the total length d0 in the circumferential direction. That is, the longitudinal length d1 of the mouth-side engaging protrusions 13 and the number of the mouth-side engaging protrusions 13 can be appropriately designed. Moreover, the longitudinal lengths d1 of two or more mouth-side engaging projections 13 may be different from each other, or may be equal to each other.

Further, when the number of the mouth-side engaging protrusions 13 is two or more, there is no particular limitation on the installation position of the mouth-side engaging protrusions 13, and FIGS. 3, the installation position of the mouth-side engaging protrusions 13 is set to the position where the two mouth-side engaging protrusions 13 face each other, and the installation positions of the two mouth-side engaging protrusions 13 are set to the positions of the mouth. Although the first interval d2 is provided in the circumferential direction of the portion 11, other installation positions may be used. The two or more mouth-side engaging protrusions 13 may be installed with different first intervals d2, or all may be installed with the same first intervals d2.

Further, the shape of the mouth-side engaging convex portion 13 is not particularly limited, and in FIGS. A semi-polygonal columnar shape, a semi-cylindrical columnar shape, or the like may be used.

The configuration of the slope portion 14 is not particularly limited, and in FIGS. 1A, 1B, 2A, 2B, and 3, it is configured to have a substantially right-angled triangular shape when viewed from the side. It may be configured in an arc shape or the like.

Further, the angle of the inclined surface 14a of the slope portion 14 is not particularly limited. It may be within the range of degrees.

In addition, there is no particular limitation on the length of the mouth portion 11 in the slope portion 14 in the circumferential direction. Although d2 is made equal to the first interval d2 between the two mouth-side engaging projections 13, it may be shorter than the first interval d2. The circumferential length d2 of the mouth portion 11 in the slope portion 14 may be, for example, in the range of 1/4 to 1/2 of the longitudinal length of the cap-side engaging protrusion 22. FIG.

Moreover, the number of the slope portions 14 is not particularly limited, and in FIGS. Although the portion 14 is provided, the slope portion 14 may be provided at one end portion 13a in the longitudinal direction of any one of the mouth-side engaging projections 13 . The number of slope portions 14 is appropriately designed according to the number of mouth-side engaging protrusions 13 .

Further, as shown in FIGS. 4A and 4B, the thickness t1 of the slope portion 14 is not particularly limited. 13 can be thinner than the thickness t2. Here, the thickness means the height along the direction perpendicular to the plugging direction. The thickness t1 of the slope portion 14 can be, for example, in the range of 1/4 to 1 of the thickness t2 of the mouth-side engaging protrusion 13. FIG.

The number and configuration of the cap-side engaging protrusions 22 are not particularly limited, and in FIGS. The length d3 in the longitudinal direction of the side engaging protrusion 22 is approximately one- third of the total length d0 in the circumferential direction of the mouth 11, and the length in the longitudinal direction of the mouth side engaging protrusion 13 is d1, but the number of cap-side engaging protrusions 22 may be one or two or more. It may be in the range of 1/6 to 1/2 of the total length d0 in the circumferential direction. In other words, the longitudinal length d3 of the cap-side engaging protrusions 22 and the number of the cap-side engaging protrusions 22 can be appropriately designed. Moreover, the longitudinal lengths d3 of two or more cap-side engaging protrusions 22 may be different from each other, or may be equal to each other. Here, if the length d3 of the cap-side engaging protrusion 22 is equal to the length d1 of the mouth-side engaging protrusion 13 or shorter than the length d1 of the mouth-side engaging protrusion 13, This is preferable because the cap-side engaging protrusions 22 are easily locked between the flange 12 and the mouth-side engaging protrusions 13 .

Further, when the number of the cap-side engaging protrusions 22 is two or more, there is no particular limitation on the installation position of the cap-side engaging protrusions 22, and FIGS. , the installation positions of the cap-side engaging protrusions 22 are set to positions where the two cap-side engaging protrusions 22 face each other, and the installation positions of the two cap-side engaging protrusions 22 are set to the circumferential direction of the mouth portion 11. Although the second distance d4 is provided to the , other installation positions may be used. The two or more cap-side engaging protrusions 22 may be installed with different second intervals d4, or may be installed with the same second intervals d4.

Here, the second spacing d4 is preferably equal to the first spacing d2, depending on the length d1 of the mouth-side engaging protrusion 13 and the length d3 of the cap-side engaging protrusion 22. Designed accordingly.

Further, the shape of the cap-side engaging protrusion 22 is not particularly limited, and in FIGS. It may be in the shape of a polygonal column, a semi-elliptical column, or the like. 1A, 1B, 2A, 2B, and 3, the shape of the cap-side engaging convex portion 22 is configured to be the same as the shape of the mouth-side engaging convex portion 13. It may be configured in a shape different from the shape of the joint protrusion 13 .

Moreover, the thickness t3 of the cap-side engaging protrusion 22 is not particularly limited, and is equivalent to the thickness t2 of the mouth-side engaging protrusion 13 in FIGS. However, if the cap-side engagement projection 22 is locked between the flange 12 of the mouth portion 11 and the mouth-side engagement projection 13, the thickness t3 of the cap-side engagement projection 22 is It may be higher or lower than the thickness t<b>2 of the mouth side engaging projection 13 .

Further, the shape of one end portion 22a in the longitudinal direction of the cap-side engaging convex portion 22 is not particularly limited. Although it is configured in a semi-elliptical shape so as to be , it may be configured in a semi-spherical shape, a semi-polygonal shape, or the like.

The resins forming the container body 10 and the cap 20 are not particularly limited. (PE) may be used, or another resin may be used. As for the dimensions of the mouth portion 11 and the cap 20, they may be configured in a cylindrical shape, or may be configured in a conical shape so that the length in the radial direction becomes slightly shorter toward the top. Along with this, the thickness t1 of the slope portion 14, the thickness t2 of the mouth side engaging protrusion 13, and the thickness t3 of the cap side engaging protrusion 22 are appropriately adjusted.

By the way, in the present invention, furthermore, a ring-like projection protrudes along the circumferential direction of the mouth portion 11 at a predetermined position on the outer peripheral surface of the mouth portion 11 that is higher than the position of the mouth-side engaging protrusion 13, A sealing portion 15 that can be brought into close contact with the inner peripheral surface of the cylindrical portion 21 when the cylindrical portion 21 of the cap 20 is plugged into the mouth portion 11 may be further provided. For example, in FIGS. 1A, 1B, 2A and 2B, two seals 15 are provided on mouth 11 . As a result, when the cap 20 is plugged onto the mouth portion 11 , the seal portion 15 of the mouth portion 11 is in close contact with the cylindrical portion 21 of the cap 20 , so that the mouth portion 11 of the container body 10 is sealed by the cap 20 . be. Therefore, in the case of the stopper-type cap container 1 that employs the configuration of the present invention and requires a sealed state, the sealed state can be maintained by appropriately providing the seal portion 15 .

For example, as shown in FIGS. 8 and 9, a part of the cap-side engaging projection 22 contacts the side surface of the slope portion 14, and the other part of the cap-side engaging projection 22 contacts the outer peripheral surface of the mouth portion 11. When they are brought into contact with each other, a slight gap is generated between the cap-side engaging protrusion 22 and the mouth-side engaging protrusion 13 . The mouth portion 11 of the container body 10 is sealed by the cap 20 by being in close contact with the portion 21 .

Here, the number and configuration of the seal portions 15 are not particularly limited, and although the number of the seal portions 15 is two in FIGS. I don't mind.

Further, in the present invention, the upper inner peripheral surface of the mouth portion 11 extends downward in a cylindrical shape on the lower surface of the upper portion of the cap 20, and when the cylindrical portion 21 of the cap 20 is plugged into the mouth portion 11, An inner ring 23 that is in close contact with 11S may be further provided. For example, in FIGS. 2A, 2B, 4B, 5A, 5B, 6, 7A, 7B, and 9, when the cap 20 is capped, the inner ring 23 of the cap 20 is positioned above the mouth portion 11. is in close contact with the inner peripheral surface 11S of. As a result, the opening 11 of the container body 10 can be sealed with the cap 20 . By properly providing the inner ring 23 to the stopper-type cap container 1, which requires a closed state, as in the above-described sealing portion 15, the closed state can be maintained.

Further, in the present invention, the cap 20 further extends downward in an annular shape on the lower surface of the upper portion of the cap 20, and when the cylindrical portion 21 of the cap 20 is plugged into the mouth portion 11, it contacts the upper end portion 11a of the mouth portion 11. A contact ring 24 may be further provided. For example, in FIG. 10, the contact ring 24 of the cap 20 contacts the upper end portion 11a of the mouth portion 11 when the cap 20 is plugged. In this case, due to the presence of the contact ring 24, the lower end portion 21a of the cylindrical portion 21 may not come into contact with the flange 12 of the mouth portion 11. The opening 11 of the container body 10 can be further sealed with the cap 20 . By appropriately providing the contact ring 24 to the stopper-type cap container 1 that requires a sealed state, such as the seal portion 15 and the inner ring 23 described above, the sealed state can be strengthened. Any one of these may be used as the seal portion 15, the inner ring 23, and the contact ring 24, or an appropriate combination thereof may be used.

In addition, in the present invention, the cylindrical portion 21 of the cap 20 is protruded near the position of the slope portion 14, and when the cylindrical portion 21 of the cap 20 is plugged into the mouth portion 11 and comes into contact with the cap side engaging convex portion 22, the cap side A guide portion 16 that guides the engaging protrusion 22 to the vicinity directly above the mouth-side engaging protrusion 13 may be further provided. For example, as shown in FIGS. 11A and 11B, the guide portion 16 is provided directly above the position of the slope portion 14, and the upper tip thereof extends from the other longitudinal end portion 13b of the mouth-side engaging projection 13. The lower tip is positioned toward one end 13a in the longitudinal direction of the mouth-side engaging projection 13, and is formed in a right-angled triangle that slopes downward from the upper tip to the lower tip. Further, since the guide portion 16 has a predetermined thickness, the lower end of the guide portion 16 is provided with a guide portion inclined surface 16 a that is inclined from the side surface of the guide portion 16 to the outer side surface of the mouth portion 11 .

As a result, as shown in FIG. 12, when the user plugs the cap 20, when the cap-side engaging projection 22 of the cap 20 is located near the top of the slope portion 14, it first contacts the guide portion 16, By the inclined surface of the right triangle of the guide part 16, it is moved and guided to the vicinity of just above the mouth part side engaging convex part 13. As shown in FIG. Then, the cap-side engaging protrusion 22 climbs over the mouth-side engaging protrusion 13, enters between the flange 12 of the mouth 11 and the mouth-side engaging protrusion 13, and is locked. In other words, due to the presence of the guide portion 16, the cap-side engaging projection 22 is arranged directly below the mouth-side engaging projection 13 without straddling the slope portion 14 during capping. It is possible to appropriately abut on the outer peripheral surface.

In this state, the user moves the cap 20 along the direction from one longitudinal end 13a of the mouth-side engagement projection 13 to the other longitudinal end 13b of the mouth-side engagement projection 13 . , the longitudinal one end 22a of the cap-side engaging projection 22 immediately rides on the inclined surface 14a of the slope portion 14, so that the cap-side engaging projection 22 can be easily moved as described above. It is possible to ride on the mouth-side engagement projection 13, and the removal of the cap 20 can be facilitated.

By providing the guiding portion inclined surface 16a when the cap 20 is rotated, even if the cap-side engaging convex portion 22 comes into contact with the guiding portion inclined surface 16a, the guiding portion can be rotated through the guiding portion inclined surface 16a. Since the cap 20 can be easily mounted on the cap 16, removal of the cap 20 can be facilitated.

Here, the shape of the guide portion 16 is not particularly limited, but for example, as shown in FIG. , the lower tip is positioned toward the other end 13b in the longitudinal direction of the mouth-side engaging protrusion 13, and may be configured in a right-angled triangle that slopes downward from the upper tip to the lower tip. . The upper tip of the guide portion 16 is located in the center, and the two lower tips are positioned toward one end 13a of the mouth-side engaging projection 13 in the longitudinal direction and toward the longitudinal direction of the mouth-side engaging projection 13. It may be configured in a triangular shape, located at each of the other ends 13b of the direction and sloping downwards from the upper extremity to each of the two lower extremities. In this case, each of the two lower extremities of the triangle is provided with a guiding portion inclined surface 16a.

Further, the guide portion 16 is formed in a triangular shape, and from the lower end of the one longitudinal end portion 13a of the mouth-side engagement projection 13 to the upper end of the slope portion 14 (the longitudinal direction of the mouth-side engagement projection 13). A linear guiding portion inclined surface 16a1 extending at one end portion 13a) of the direction may be provided. The thickness of the linear guiding portion inclined surface 16a1 is designed to be thin so that the cap-side engaging convex portion 22 can be easily climbed over. Here, the length of the guide portion 16 described above is equal to the length of the slope portion 14. However, the guide portion 16 is not limited to this. It may be spherical or polygonal. In addition, in the present invention, for example, a single cap container in which one cap is attached by a capping type is assumed. It is not limited to containers, and can be widely applied to containers for stoppering caps such as discharge cap containers and test containers.

For example, as shown in FIGS. 14A and 14B, the present invention may be applied to a shallow, wide-opening jar container for cosmetics such as creams and gels with high viscosity. In the case of a jar container, since the thickness of the cap 20 is also thin, for example, an annular or disk-shaped elastic body such as a packing may be provided on the lower surface of the upper portion of the cap 20 to maintain the sealed state. Moreover, as shown in FIGS. 15A and 15B, the present invention may be applied to containers for liquids with low viscosity (spout pouch containers). In the case of a liquid container, for example, by appropriately adding the seal portion 15 and the inner ring 23 described above, the sealed state can be maintained. Of course, a further contact ring 24 may be added.

INDUSTRIAL APPLICABILITY As described above, the stopper-type cap container according to the present invention contains not only liquids such as food seasonings, medicines, cosmetics, shampoos, rinses and liquid soaps, but also semi-solid contents such as creams and gels. As a container for a capping type cap that can be easily removed even if the cap is capped on the mouth without worrying about the position of the cap with respect to the mouth It is valid.
