Hereinafter, the present invention will be described in more detail with reference to the drawings.

The container 1 with a cap, which is an embodiment of the present invention shown in FIG. 1, can be used for storing, for example, creamy cosmetics as contents, and the container body 10 and the cap 20 are attached. Have.

The container body 10 includes a cylindrical mouth portion 11, a cylindrical body portion 12 connected to the mouth portion 11, and a circular bottom portion 13 that closes the lower end of the body portion 12, and has a wide-mouthed bottle shape (jar shape) as a whole. It has become. The inside of the container body 10 is a storage space S for storing the contents, and the contents can be filled in the storage space S through the mouth portion 11 and the contents are stored in the storage space S through the mouth portion 11. You can take out things.

The mouth portion 11 is formed to have an outer diameter smaller than that of the body portion 12, and a male screw 11a is integrally provided on the outer peripheral surface thereof. The male screw 11a is provided on the lower side (side of the body portion 12) from the vertical center position of the outer peripheral surface of the mouth portion 11 in the vertical direction (axial direction), and is located below the central position of the outer peripheral surface of the mouth portion 11 in the vertical direction. It is not provided on the upper side.

In the present embodiment, the container body 10 is made of synthetic resin formed by injection molding a synthetic resin material, but it may be made of another material such as glass or metal. Good.

Further, in the present embodiment, the container body 10 has a wide-mouthed bottle shape, but if it has a mouth portion 11, it may have another shape such as a bottle shape.

The cap 20 is made of a synthetic resin such as polypropylene resin, and has an eclipsed cylindrical outer shape including a circular top wall 21 and a cylindrical peripheral wall 22.

A female screw 22a is integrally provided below the central position of the inner peripheral surface of the peripheral wall 22 in the vertical direction (axial direction). The portion of the peripheral wall 22 where the female screw 22a is integrally provided is the screw forming portion 22A. The cap 20 is detachably attached to the mouth portion 11 by screwing the female screw 22a to the male screw 11a provided on the mouth portion 11.

The outer diameter of the peripheral wall 22 is substantially the same as the outer diameter of the body 12 of the container body 10. When the cap 20 is attached to the mouth 11 of the container body 10, the outer peripheral surface of the container body 10 and the cap are attached. The outer peripheral surfaces of 20 are smoothly connected to each other. As a result, the container 1 with a cap has a high aesthetic appearance in which the container body 10 and the cap 20 have a sense of unity.

Inside the cap 20, a circular sheet-shaped sealing material 23 is mounted on the inner surface of the top wall 21. The sealing material 23 is adhered to the inner surface of the top wall 21 of the cap 20 using an adhesive and is fixed to the cap 20. When the cap 20 is attached to the mouth portion 11, the open end (upper end) of the mouth portion 11 elastically contacts the sealing material 23, so that the mouth portion 11 is hermetically or airtightly sealed by the cap 20. .. In the present embodiment, the sealing material 23 is fixed to the inner surface of the top wall 21 of the cap 20 by adhesion using an adhesive, but the present invention is not limited to this, and for example, the inner peripheral surface of the peripheral wall 22 is used. The sealing material 23 is attached to the cap 20 by providing an annular or intermittent rib on the rib and engaging the outer peripheral edge of the sealing material 23 in an undercut shape to hold the sealing material 23 on the cap 20. The configuration to be used can be changed in various ways.

The peripheral wall 22 of the cap 20 has a gripping portion 22B having a cylindrical outer peripheral surface between the screw forming portion 22A provided with the female screw 22a and the top wall 21.

As shown in FIGS. 2 and 3, the grip portion 22B provided on the peripheral wall 22 of the cap 20 has a plurality of thin-walled portions 24 and a plurality of thick-walled portions 25. The thin-walled portions 24 and the thick-walled portions 25 are provided in the same number as each other, and are provided alternately side by side in the circumferential direction. In the case shown in the figure, the grip portion 22B has a configuration in which four (even number) thin-walled portions 24 and four (even-numbered) thick-walled portions 25 are provided alternately in the circumferential direction.

The radial thickness of each of the four thin-walled portions 24 is smaller than the radial thickness of the peripheral wall 22 at the screw forming portion 22A. In the case shown in the drawing, the radial thickness of each thin portion 24 is less than half the radial thickness of the peripheral wall 22 in the screw forming portion 22A. The radial thicknesses of the four thin-walled portions 24 are the same as each other and are constant at each position in the circumferential direction. Since the thin-walled portion 24 is formed to be thinner in the radial direction than the radial thickness of the peripheral wall 22 in the screw-forming portion 22A, it can be easily elastically deformed inward in the radial direction from the screw-forming portion 22A. it can.

The radial thickness of each of the four thick portions 25 is thicker than the radial thickness of the thin portion 24. In the case shown in the drawing, the radial thickness of the thick portion 25 is obtained by adding the amount of protrusion of the female screw 22a from the inner peripheral surface of the peripheral wall 22 in the radial direction to the radial thickness of the peripheral wall 22 in the screw forming portion 22A. It is said to be thick. The radial thicknesses of the four thick portions 25 are the same as each other. Since the thick portion 25 is formed to be thicker in the radial direction than the thin portion 24, it is less likely to be elastically deformed inward in the radial direction than the thin portion 24.

Each of the four thick portions 25 has a shape that increases the wall thickness in the radial direction by projecting inward in the radial direction with respect to the thin portion 24. That is, the grip portion 22B has a cylindrical shape whose outer peripheral surface has a constant outer diameter over the entire circumference, but the grip portion 22B has a wall thickness due to the change in the inner diameter of the inner peripheral surface in the circumferential direction. It is configured to include a thin thin portion 24 and a thick thick portion 25.

As described above, the grip portion 22B has a configuration in which thin-walled portions 24 and thick-walled portions 25 having different wall thicknesses in the radial direction are alternately arranged in the circumferential direction.

In the present embodiment, the circumferential lengths of the four thin-walled portions 24 are the same as each other, and the circumferential lengths of the four thick-walled portions 25 are also the same as each other. That is, in the grip portion 22B, four thin-walled portions 24 having the same circumferential length are arranged at equal intervals in the circumferential direction, and four thick-walled portions 25 having the same circumferential length are arranged at equal intervals in the circumferential direction. It is composed.

The circumferential length of each of the four thick portions 25 is shorter than the circumferential length of the thin portion 24. As a result, the grip portion 22B has a configuration in which the ratio of the thin-walled portion 24 to the entire range in the circumferential direction is larger than that of the thick-walled portion 25. Further, each of the four thick portions 25 has a length in the vertical direction (length in the axial direction) longer than the length in the circumferential direction, and is formed in a columnar shape extending along the axial direction. In the case shown in the drawing, the cross-sectional shape of the thick-walled portion 25 formed in a columnar shape in a plan view is a trapezoidal shape in which the circumferential width narrows from the outer side in the radial direction to the inner side in the radial direction.

In the capped container 1 having the above configuration, when the cap 20 is attached to and detached from the mouth portion 11, the user grips the outer peripheral surface of the grip portion 22B of the cap 20 with a finger and rotates the cap 20. The cap 20 can be easily rotated with respect to the mouth portion 11.

That is, in the capped container 1 of the present embodiment, a thin portion having different radial wall thicknesses between the screw forming portion 22A on which the female screw 22a of the peripheral wall 22 of the cap 20 is formed and the top wall 21. Since the grip portion 22B in which the 24 and the thick portion 25 are provided alternately arranged in the circumferential direction is provided, as shown in FIG. 4, the outer peripheral surface of the grip portion 22B of the cap 20 is sandwiched between fingers. When gripped with a screw, the thin portion 24 is elastically deformed inward in the radial direction along the shape of the finger due to the force applied from the finger between the pair of thick portions 25. In this way, since the peripheral wall 22 can be deformed into a shape that fits the finger, the finger can be made difficult to slip in the circumferential direction with respect to the cap 20. Further, when the cap 20 is rotated by the finger, the finger is caught by the thick portion 25 and locked, so that the finger can be made less slippery with respect to the cap 20 in the circumferential direction. Therefore, when the cap 20 is attached to and detached from the mouth portion 11, it is possible to suppress slippage of the finger with respect to the peripheral wall 22 of the cap 20 in the circumferential direction so that the rotation operation of the cap 20 can be performed more easily. ..

On the other hand, unlike the container with a cap 1 of the present embodiment, in the case where the peripheral wall of the cap has a constant wall thickness in the circumferential direction, when the peripheral wall of the cap is gripped so as to be sandwiched between fingers, Since the peripheral wall is deformed so as to have an elliptical shape as a whole and does not deform into a shape that fits the finger, the finger cannot be sufficiently locked with respect to the peripheral wall, and the finger is placed in the circumferential direction with respect to the cap. Can't be slippery.

Further, in the container 1 with a cap of the present embodiment, the thin-walled portion 24 provided on the grip portion 22B is elastically deformed inward in the radial direction to prevent the fingers from slipping. For example, it is possible to suppress the slipping of the finger with respect to the peripheral wall 22 of the cap 20 in the circumferential direction without performing knurling, spline processing, or providing a soft film. Therefore, when the capped container 1 of the present embodiment is used for an application such as a cosmetic container, the outer peripheral surface of the cap 20 is glossy, for example, without providing the above-mentioned processed portion or soft coating. While making the appearance of the cap 20 more aesthetically pleasing by giving it a smooth finish, the rotation operation of the cap 20 can be easily performed by surely suppressing the sliding of the finger with respect to the peripheral wall 22 of the cap 20 in the circumferential direction. Can be. In this case, the outer peripheral surface of the container body 10 can also have a glossy and smooth finish like the cap 20.

Further, in the capped container 1 of the present embodiment, in the grip portion 22B, the circumferential length of the thin portion 24 is made longer than the circumferential length of the thick portion 25, so that the grip portion 22B of the cap 20 is made longer. When the outer peripheral surface of the is gripped so as to be sandwiched between the fingers, the fingers can be easily arranged on the thin portion 24. Thereby, when the gripping portion 22B of the cap 20 is gripped by the finger, the finger is naturally located on the thin-walled portion 24, so that the rotation operation of the cap 20 can be performed more easily.

Further, in the container 1 with a cap of the present embodiment, the circumferential lengths of the four thin-walled portions 24 are made the same as each other, and the circumferential lengths of the four thick-walled portions 25 are made the same as each other. The above-mentioned effect can be obtained in the same manner regardless of which position of the gripping portion 22B of the cap 20 in the circumferential direction is gripped by fingers.

Further, when an even number of thin-walled portions 24 and thick-walled portions 25 are provided as in the capped container 1 of the present embodiment, the outer peripheral surface of the gripped portion 22B of the cap 20 is sandwiched between fingers. When gripped, both fingers can be positioned on the thin portion 24 so that the rotation operation of the cap 20 can be performed more easily.

Further, in the container 1 with a cap of the present embodiment, each of the four thick portions 25 is formed in a columnar shape having an axial length longer than the circumferential length, so that the thin wall portion occupies the entire circumferential direction. While increasing the proportion of the portion 24, the finger can be securely locked when the cap 20 is rotated, so that the rotation operation of the cap 20 can be performed more easily.

Further, in the container 1 with a cap of the present embodiment, the thick portion 25 is provided so as to project inward in the radial direction with respect to the thin portion 24, and the outer diameter of the outer peripheral surface of the grip portion 22B is constant over the entire circumference. Since it is formed in a cylindrical shape, the above effect can be obtained while enhancing the appearance of the peripheral wall 22 of the cap 20.

Further, in the capped container 1 of the present embodiment, the radial thickness of the thin portion 24 is set to half or less of the radial thickness of the peripheral wall 22 in the screw forming portion 22A, so that the outer circumference of the grip portion 22B of the cap 20 is set. The thin-walled portion 24 can be more easily elastically deformed inward in the radial direction by the fingers gripped so as to sandwich the surface, so that the rotation operation of the cap 20 can be performed more easily.

Further, in the case where the container body 10 is formed in the shape of a wide-mouthed bottle like the container 1 with a cap of the present embodiment, the cap 20 is also formed to have a large outer diameter in accordance with the mouth portion 11 formed in the wide mouth. As a result, the rotational force required for attaching and detaching the cap 20 to and from the mouth portion 11 also increases, but even in such a case, the above configuration makes it possible to easily perform the rotational operation of the cap 20. Can be done.

It goes without saying that the present invention is not limited to the above-described embodiment and can be variously modified without departing from the gist thereof.

For example, in the above-described embodiment, the container with a cap 1 is used for storing creamy cosmetics and the like as contents, but the present invention is not limited to this and is used for storing other contents. It can also be used.
