Description

The present invention relates to a screw cap for closing a container body.

A screw cap for closing a container body having a threaded groove on the outer surface of the mouth and neck is known to have a threaded groove formed on the inner surface of a peripheral wall hanging from the outer periphery of the top wall of the lid ( Patent Document 1).

JP-A-2004-35011

In the screw cap of Patent Document 1, a user grips a peripheral wall having a thread formed on the inner surface (hereinafter, such a configuration is referred to as a “threaded peripheral wall”) and screws the screw into the outer surface of the mouth neck with a thread groove. It is worn or screwed away from the outer surface of the mouth and neck.
However, when the content is a liquid that easily solidifies, such as paint, and the cap is removed from the mouth and neck and the content is taken out, the content is the screw groove forming portion on the outer surface of the mouth and neck. It is possible that it adheres to the upper edge of the mouth and neck.
In such a case, if the user refits the cap on the mouth and neck without wiping off the adhered contents, the contents will be between the thread groove of the mouth and neck and the thread of the cap, or the mouth. Between the upper end of the neck and the top wall of the cap, it may solidify while adhering to both the mouth and neck and the cap.
In that case, the next time the cap is to be removed, the cap may not be easily removed. Especially for elderly people and children with weak grip strength, it will be very difficult to remove the cap.

An object of the present invention is to propose a screw cap for closing a container body that can be easily removed from the mouth and neck of the container body.

The first means is a screw cap for closing the container body, in which the lid top wall 10 is stretched on the upper part of the peripheral wall P with a screw that can be screwed to the outer surface of the mouth neck 102 of the container body.
A plurality of flexible support pieces 40 are projected outward from the outer surface of the threaded peripheral wall P.
An operation ring 42 is supported on the outer end portion 40b of the flexible support piece 40 so as to surround the threaded peripheral wall P, and the operation ring 42 is supported.
The flexible support piece 40 can be bent and deformed at least in the circumferential direction, and when the operation ring 42 is pushed in from the outside, the inner peripheral surface of the operation ring 42 becomes the screwed peripheral wall P due to the bending deformation . It is provided so as to come into contact with the outer peripheral surface of the
A knurled portion A is formed on one of the outer peripheral surface of the threaded peripheral wall P and the inner peripheral surface of the operation ring 42, and an engaging convex portion b is formed on the other so that the operation ring 42 can be engaged with each other when the operation ring 42 is pushed in. ,
By rotating the operation ring 42 in a state where the knurled portion A and the engaging convex portion b are engaged with each other, a rotational force on the operating ring 42 is transmitted through the knurled portion A and the engaging convex portion b. It was configured to be transmitted to the threaded peripheral wall P.

In this means, as shown in FIG. 2, it is proposed to provide an operation ring 42 so as to surround the peripheral wall P with a screw for screwing to the neck of the container body.
This operation ring is supported by a plurality of flexible support pieces 40 protruding from the threaded peripheral wall P, and the knurled portion A is provided on one of the outer peripheral surface of the threaded peripheral wall P and the inner peripheral surface of the operation ring 42. , And an engaging convex portion b on the other side, respectively.
In the illustrated example, the outer peripheral knurled portion A1 is formed on the outer peripheral surface of the threaded peripheral wall P, and the inner peripheral knurled portion A2 is formed on the inner peripheral surface of the operation ring 42, but this is only one embodiment.
Then, when the operation ring 42 is pushed inward, the knurled portion A and the engaging convex portion b can be engaged with each other as shown in FIG. 3A. When the operation ring 42 is rotated in this meshed state as shown in FIG. 3B, the rotational force to the operation ring 42 is transmitted to the threaded peripheral wall P via the knurled portion A and the engaging convex portion b. It is provided so as to.
In this configuration, as shown in FIG. 1 or 6, the distance R from the rotation center O to the outer surface of the operation ring 42 is larger than the distance r from the rotation center O of the screw cap 2 to the outer periphery of the threaded peripheral wall P. , The torque on the threaded peripheral wall P increases, and the lid opening operation becomes easy.

The second means has the first means, and the operation ring 42 is formed into an elastic ring that can be deformed from a perfect circular shape to an elliptical shape by an operation of gripping from both sides in the radial direction.

In this means, as shown in FIGS. 3 (A) to 3 (C), the operation ring 42 is formed so as to be able to be deformed from a perfect circular shape to an elliptical shape by an operation of gripping from both sides in the radial direction. ing. Since the operation ring is deformed like an elliptical knob, the pseudo-elliptical knob can be used to open the lid more efficiently.

The third means has a first means or a second means, and the tubular handle H extends upward from the upper part of the threaded peripheral wall P.

As shown in FIG. 1, the present means proposes to extend the tubular handle H upward from the upper part of the threaded peripheral wall P. For example, when the user grips the screw cap in order to perform capping after filling the content liquid or to close the cap after use, which part of the cap is gripped affects usability. Since the present means is provided with a tubular handle extending from the threaded peripheral wall P, the operation of screwing the threaded peripheral wall P to the mouth neck 102 can be reliably performed, which is convenient.

The fourth means has any of the first to third means, and has a small-diameter screw tube portion having a screw thread 6 capable of screwing the threaded peripheral wall P to the mouth neck 102. It is formed on a double peripheral wall in which a large-diameter fitting ring 22 is fitted to the outer surface of 4.
The screw cylinder portion 4 and the fitting ring 22 are configured to rotate integrally.
The screw cap 2 having the lid top wall 10 stretched on the upper inner surface of the screw cylinder portion 4 and the fitting ring 22 are connected to the operation ring 42 via the flexible support piece 40. The outer cap 20 was formed as a separate body.

In this means, as shown in FIG. 1, the peripheral wall P with a screw has a double structure in which the fitting ring 22 is fitted to the outer surface of the screw cylinder portion 4 described above.
The screw cap of this means consists of two members: a screw cap 2 including a screw cylinder portion 4, and an outer cap 20 for supporting an operation ring 42 from a fitting ring 22 via a flexible support piece 40. It is advantageous because it is possible to select a material suitable for exhibiting each action (for example, the former is a screw fastening action and the latter is an elastic bearing action).

The fifth means has any one of the first to third means, and the threaded peripheral wall P is a single peripheral wall, and is formed as an integrally molded product as a whole.

In this means, as shown in FIG. 6, the threaded peripheral wall P is a single peripheral wall, and is formed as an integrally molded product as a whole. As a result, the number of parts can be reduced.

According to the invention according to the first means, the operation ring 42 is supported by a plurality of flexible support pieces 40 so as to surround the threaded peripheral wall P, and one of the outer peripheral surface of the threaded peripheral wall P and the inner circumference of the operation ring. A knurled portion A is provided on the knurled portion A, and an engaging convex portion b is provided on the other side. Since it is transmitted to the screwed peripheral wall P via the above torque, the torque can be increased and the lid opening operation becomes easy.
According to the invention according to the second means, since the operation ring 42 is formed into an elastic ring that can be deformed from a perfect circular shape to an elliptical shape by an operation of gripping from both sides in the radial direction, it is more efficient. The lid can be opened.

It is a half sectional view of the screw cap which concerns on 2nd Embodiment of this invention.

1 to 5 show a screw cap 1 according to a first embodiment of the present invention.
The screw cap 1 is for being attached to the outer surface of the mouth neck 102 of the container body 100.
As shown in FIG. 1, the basic configuration of the screw cap 1 is such that a plurality of operation rings 42 surrounding the screwed peripheral wall P are flexible around the threaded peripheral wall P that can be screwed to the outer surface of the mouth neck 102. It was made to be supported by the sex support piece 40.

In the present embodiment, as shown in FIG. 1, the screw cap 1 is composed of a screw cap 2 and an outer cap 20, but these structures can be appropriately changed. Hereinafter, the structure of the screw cap will be described with reference to the drawings.

The screw cap 2 has a screw cylinder portion 4 that can be screwed to the outer surface of the mouth neck portion 102, and the lid top wall 10 is stretched on the inner surface of the upper end portion of the screw cylinder portion 4. The screw cap 2 can be formed of, for example, a synthetic resin.
A screw thread 6 for screwing to the outer surface of the mouth neck 102 is formed on the inner surface of the screw cylinder portion 4. Further, an engaging protrusion 7 is attached to the lower portion of the outer surface of the screw cylinder portion 4.
Further, in the illustrated example, an extension cylinder portion 8 having a smaller outer diameter than the screw cylinder portion 4 is extended upward from the vicinity of the upper end of the screw cylinder portion 4. A vertical rib-shaped stopper 9 is formed on the outer surface of the extension cylinder portion 8.
Further, in the illustrated example, on the outside of the extension cylinder portion 8, the upper end surface of the screw cylinder portion 4 is formed in an upward step portion 4a for locking to the upright cylinder portion 32 described later.
A seal cylinder portion 12 hangs down from the lower surface of the lid top wall 10. The seal cylinder portion 12 is formed so as to be able to come into contact with the inner surface of the upper end portion of the mouth neck portion in a liquid-tight manner.

In the illustrated example, a sealing ring 14 is attached to the lower end of the screw cylinder portion 4 via the breaking portion 16. A locking projection 15 is projected upward and inward from the inner surface of the sealing ring 14. The upper end of the locking projection piece 15 is in contact with the lower surface of the retaining protrusion 106 of the mouth neck 102, which will be described later.

The outer cap 20 is formed of a fitting ring 22, an upright cylinder portion 32, a plurality of flexible support pieces 40, and an operation ring 42.
The fitting ring 22 is a vertically oriented cylinder fitted to the outer surface of the screw cylinder portion 4. An outer peripheral knurled portion A1 is formed on the outer peripheral surface of the fitting ring 22. This will be described later.
Further, a locking convex portion 24 is attached to the lower inner surface of the fitting ring 22. The locking protrusion 24 is engaged with the lower surface of the engaging protrusion 7.
In the present embodiment, the threaded cylinder portion 4 and the fitting ring 22 described later form the above-mentioned peripheral wall P with a screw.
The upright cylinder portion 32 has a smaller outer diameter than the fitting ring 22, and extends upward from the upper end of the fitting ring 22 via a reduced diameter portion having a downward step portion 30. The downward step portion 30 is locked to the upward step portion 4a of the screw cylinder portion 4.
The upright cylinder portion 32 shown in the figure has a ridged cylinder shape, and a top plate 38 is stretched on the inner surface of the upper end portion of the cylinder wall.
An inner rib, which is a stopper receiving portion 34, is vertically provided on the inner surface of the standing cylinder portion 32. The stopper 9 of the screw cap 2 is locked to the stopper receiving portion 34.
The stopper 9 and the stopper receiving portion 34 form a rotation retaining mechanism D that regulates the rotation of the outer cap 20 with respect to the screw cap 2.
In the present embodiment, the upright cylindrical portion 32 has a role as a tubular handle H. A vertical rib-shaped non-slip 36 is attached to the outer peripheral surface of the standing cylinder portion 32. As a result, it is possible to prevent the finger from slipping when the tubular handle H is gripped and the operation of capping the screw cap after filling with the content liquid or closing the screw cap after use is performed.

As shown in FIG. 2, a plurality of flexible support pieces 40 are outwardly projected from the outer surface of the fitting ring 22, and the operation ring 42 is supported by the outer end portion 40b of the flexible support pieces 40. ing.

As shown in FIGS. 3A to 3C, the flexible support piece 40 makes the operation ring 42 flexible so that the operation ring 42 can be rotated with respect to the fitting ring 22. In addition, it is preferably elastically supported.
As shown in FIG. 3A, each flexible support piece 40 has a flexible support on the side opposite to the pushing direction (left side in the figure) when the operation ring 42 is pushed toward the fitting ring 22. Like the remaining two flexible support pieces 40, they are formed so that they can be bent and deformed in the circumferential direction so that they can be stretched (preferably elastically stretched) like the piece 40.
In this embodiment, the flexible support piece 40 is formed on a vertical plate. In a more preferred illustration, the flexible support piece 40 is formed into a vertically elongated rectangle (substantially rectangular) as shown in FIG. By doing so, it is possible to secure a supporting force sufficient to sufficiently support the weight of the operation ring 42, and it becomes relatively easy to bend and deform as described above.
In a suitable illustrated example, three flexible support pieces 40 are provided equiangularly, but the number and arrangement thereof can be appropriately changed.
Further, in the illustrated example, each flexible support piece 40 extends in the radial direction of the fitting ring 22 from the inner end portion 40a thereof, as shown in FIG. 2, but this structure can be appropriately changed.
The width w of the flexible support piece 40 and the protrusion length L from the fitting ring 22 shown in FIG. 2 are such that the inner peripheral surface of the operation ring 42 is fitted when the operation ring 42 is pushed toward the fitting ring 22. It is designed so that it can come into contact with the outer peripheral surface of the ring 22.

The operation ring 42 is supported by the flexible support piece 40 so as to concentrically surround the fitting ring 22 in the state before use shown in FIG.
The role of the operation ring 42 is to be able to position a point (force point) to which a force is applied for the rotation operation farther from the rotation center O of the screw cap 2 than the outer peripheral surface of the screw cap. be. That is, as shown in FIG. 1, since the distance R from the rotation center O to the outer surface of the operation ring 42 is larger than the distance r from the rotation center O to the outer surface of the screw cylinder portion 4, it acts on the screw cap. You can earn the torque to do.
As shown in FIG. 3B, the operation ring 42 is formed in an elastic cylinder that can be elastically deformed from a perfect circle to an elliptical shape by being pinched by a user from both sides with fingers. According to this configuration, the operation ring 42 is deformed like an elliptical knob when the user grips it from both sides. When the rotation operation is performed using this pseudo elliptical knob, as shown in FIG. 3B, the distance Rmax from the rotation center O of the screw cap 2 in the major axis direction of the ellipse to the outer surface of the operation ring 42. Therefore, the torque can be further increased.
In a suitable illustrated example, the operation ring 42, the flexible support piece 40, the fitting ring 22, and the upright cylinder portion 32 are integrally molded of a flexible material or an elastic material. Suitable materials include PE (polyethylene), silicon, elastomers, synthetic rubber and the like. As a result, the flexible support piece 40 can be easily bent.
In the illustrated example, as shown in FIG. 1, the operation ring 42, the flexible support piece 40, and the fitting ring 22 are formed to have the same length in the vertical direction. However, these structures can be changed as appropriate.

An inner peripheral knurled portion A2 is formed on the inner peripheral surface of the operation ring 42.
The inner peripheral knurled portion A2 and the outer peripheral knurled portion A1 of the fitting ring 22 are provided at positions facing each other on the outer peripheral surface of the fitting ring 22 and the inner peripheral surface of the operation ring 42.
The inner peripheral knurled portion A2 and the outer peripheral knurled portion A1 are formed in a vertical knurl formed by alternately arranging vertically oriented engaging convex portions b and engaging concave portions c, respectively, and are formed in the operation ring 42 as described above. When the peripheral surface abuts on the outer peripheral surface of the fitting ring 22, it is formed so as to be able to mesh with each other.
In the illustrated example, as shown in FIG. 2, the engaging convex portions b of the inner peripheral knurled portion A2 and the outer peripheral knurled portion A1 are engaged in a triangular shape having an acute angle at the tip (outer end) when viewed from above. The recess c is formed in a trapezoidal shape with a wide outside. This facilitates the engagement of the inner peripheral knurled portion A2 and the outer peripheral knurled portion A1.
However, the inner peripheral knurled portion A2 and the outer peripheral knurled portion A1 may have any form as long as they have a structure that meshes with each other.
The reason for providing the inner peripheral knurled portion A2 and the outer peripheral knurled portion A1 is to prevent the inner peripheral surface of the operation ring 42 from slipping and being caught on the outer peripheral surface of the fitting ring 22. By doing so, it is possible to prevent the flexible support piece 40 from being excessively pulled and cut when the operation ring 42 is rotated.
However, it is not necessary to provide knurled portions on both the outer peripheral surface of the fitting ring 22 and the inner peripheral surface of the operation ring 42. That is, on one of these two surfaces, the remaining engaging convex portion b and the engaging concave portion c are left, leaving one engaging convex portion b of the engaging convex portion b and the engaging concave portion c constituting the knurled portion. You can omit it.
In the illustrated example, the inner peripheral knurled portion A2 and the outer peripheral knurled portion A1 are formed over the entire circumference of the outer peripheral surface of the fitting ring 22 and the inner peripheral surface of the operation ring 42. Thereby, regardless of the direction in which the operation ring 42 is pushed inward, the inner peripheral knurled portion A2 and the outer peripheral knurled portion A1 can be engaged with each other at the pushed portion.

In FIG. 1, an example of a container body 100 to which the screw cap of the present invention is applied is drawn by an imaginary line.
The container body 100 stands up from the body to the mouth and neck 102 via the shoulder. A screw groove 104 is formed on the outer surface of the mouth neck 102, and a retaining convex portion 106 for engaging with the sealing ring 14 is provided around the lower side of the screw groove 104. Further, an annular ridge 108 is attached to the lower side of the retaining protrusion 106. These structures can be modified as appropriate.

In the above configuration, when the operation ring 42 is pushed from the outside toward the fitting ring 22 from the state of FIG. 2, as shown in FIG. 3A, the flexible support piece 40 is elastically deformed and the operation ring is deformed. The inner peripheral surface of 42 abuts on the outer peripheral surface of the fitting ring 22, and the inner peripheral knurled portion A2 and the outer peripheral knurled portion A1 engage with each other.
In this state, as shown by the arrow in FIG. 3A, when the operation ring 42 is sandwiched between both sides with fingers, the operation ring 42 is deformed from a perfect circle to an elliptical shape (see FIG. 3B).
From this state, when the operation ring 42 is rotated by hooking at least one finger in the major axis direction of the ellipse, the rotational force to the operation ring 42 is fitted via the inner peripheral knurled portion A2 and the outer peripheral knurled portion A1. It is transmitted to the ring 22 and further transmitted to the screw cap 2 which is prevented from rotating with respect to the fitting ring 22. At this time, since the distance from the rotation center O of the screw cap 2 to the force point on the surface of the operation ring 42 is large, the torque can be increased. Therefore, even if the contents adhering between the screw cap 2 and the mouth neck 102 of the container body 100 solidify, the solidified material is easily broken by the boosting action of the operation ring 42, and the screw cap 1 is opened. It can be released from the neck 102.
Therefore, regardless of the type of contents, it is very easy to use for children and people without grip strength.
After that, the tubular handle H can be gripped to perform capping after filling the content liquid and closing the cap after use.

4 and 5 show a modified example of the flexible support piece of the screw cap according to the first embodiment of the present invention.
FIG. 4 shows a shape seen from above of the flexible support piece 40 in a substantially shape, and a corner portion between the inner end portion 40a and the outer end portion 40b of the flexible support piece 40. 40c is formed.
FIG. 5 shows a plurality of flexible support pieces 40 inclined from the inner end portion 40a of the flexible support pieces to one side in the circumferential direction with respect to the radial direction of the fitting ring 22. In the illustrated example, all the flexible support pieces 40 are tilted in the opening direction (counterclockwise) of the screw cap 2.

Hereinafter, the screw cap according to another embodiment of the present invention will be described. In these explanations, the description of the same configuration as that of the first embodiment will be omitted.

FIG. 6 shows a screw cap according to a second embodiment of the present invention.
In the present embodiment, the screw cap 1 is formed by one part.
Specifically, instead of fitting the fitting ring 22 to the outer surface of the screw cylinder portion 4, as in the first embodiment, the plurality of flexible support pieces 40 are removed from the outer surface of the screw cylinder portion 4. The operation ring 42 is supported by the outer end portion 40b of these flexible support pieces 40 so as to project in the direction. In the present embodiment, the threaded peripheral wall P is formed by the screw cylinder portion 4 alone.
The inward flange 5 projects inward from the upper end of the screw cylinder portion 4. The extension cylinder portion 8 is erected from the inner circumference of the inward flange 5, and the lid top wall 10 is stretched on the inner surface of the upper end portion of the cylinder wall of the standing peripheral wall. A non-slip 36 is formed on the outer surface of the extension cylinder portion 8.
Further, the seal cylinder portion 12 hangs down from the inner circumference of the inward flange 5. The seal cylinder portion 12 is formed so as to be liquid-tightly fitted to the upper end portion of the inner surface of the mouth neck portion 102.
