Description

The present invention relates to caps.

For containers that store liquids (liquid detergents, liquid bleaches, liquid softeners, solvents, etc.) and powders (granular detergents, granular bleaches, granular seasonings, etc.), the opening of the container body A cap is provided that is detachably screwed by rotation. Fingers may slip when rotating the cap to remove it from the container body. In particular, many of the measuring caps used for liquid laundry detergents and the like are in the shape of a substantially rotating body, and are often used with wet hands, so fingers tend to slip when attaching and detaching the cap.

As a cap having an anti-slip function in the turning direction, the outer peripheral wall of the cylindrical portion of the cap has a first ridge line inclined downward in the clockwise direction when viewed from the canopy portion side, and a first ridgeline downward in the counterclockwise direction. A cap has been proposed in which a second ridge line is formed with an inclination such as (Patent Documents 1 and 2). These ridge lines form a plurality of polygonal surfaces on the outer peripheral wall of the cap.

However, with conventional caps such as those disclosed in Patent Documents 1 and 2, there is a risk that fingers may slip when pulling the cap upward from the mouth of the container body. In particular, many of the metering caps have a shape that is slightly tapered toward the top surface of the cap in consideration of removal from the mold, and a non-slip function in the height direction of the cap is also important.
In addition, it is also important to further improve the design of the cap for the purpose of improving marketability.

The outer diameter of the diameter-reduced portion 12b is reduced toward the canopy portion 14, so that the outer peripheral wall 20 is inclined with respect to the axial direction of the upper tubular portion 12 compared to the upper tubular portion main body 12a. The outer peripheral wall 20 of the upper tubular portion main body 12a is slightly inclined with respect to the axial direction of the upper tubular portion 12 at an inclination angle smaller than that of the diameter-reduced portion 12b so that the outer diameter of the upper tubular portion body 12a decreases toward the canopy portion 14. Inclined.

A plurality of first ridgelines 22 , a plurality of second ridgelines 24 , and a plurality of third ridgelines 26 are formed on the grip portion 20 a of the outer peripheral wall 20 of the upper cylindrical portion 12 . The grip portion 20a is a region extending from the lower end of the outer peripheral wall 20 to 95% of the height H of the upper tubular portion 12 in the axial direction of the upper tubular portion 12 .

The plurality of first ridgelines 22 in this example are formed at equal intervals in the circumferential direction of the outer peripheral wall 20 . Similarly, the plurality of second ridgelines 24 are also formed at equal intervals in the circumferential direction of the outer peripheral wall 20 .
In addition, in the present invention, the first ridgeline and the second ridgeline do not have to be formed at regular intervals. In the present invention, it is preferable that the plurality of first ridgelines and second ridgelines are formed at equal intervals from the point of view of higher anti-slip effect and beautifying effect.

The first ridgeline and the second ridgeline in the cap of the present invention do not have to be formed so that fingers are always caught on the first ridgeline and the second ridgeline at the moment the cap is gripped. Even if fingers are not caught on the first or second ridgeline at the moment the cap is gripped, fingers that slip slightly when rotating the cap may get caught on the first or second ridgeline. , further slipping of the finger in the direction of rotation is suppressed. In terms of minimizing finger slippage in the direction of rotation of the cap and enhancing the beautification effect, the first ridgeline and the second ridgeline are formed in the above-described range of number and at regular intervals. more preferably.

The third ridge line 26 is formed along the entire circumference of the outer peripheral wall 20 in the circumferential direction and has a closed annular shape. In the present invention, it is preferable that the third ridgeline is annularly closed and formed along the entire circumferential direction of the outer peripheral wall of the tubular portion, in order to achieve a higher anti-slip effect and beautifying effect in the height direction. preferable.

Although there are two third edges 26 in this example, the number is not limited to two, and may be one or three or more.
In the present invention, the number of third ridgelines formed on the grip portion of the outer peripheral wall is preferably 1 to 6, more preferably 2 to 5, and even more preferably 3 to 4. If the number of the third ridge lines is equal to or greater than the lower limit of the range, the anti-slip effect of the cap 1 in the height direction is enhanced. If the number of the third ridge lines is equal to or less than the upper limit of the above range, the effect of preventing fingers from feeling pain when gripping the cap 1 is enhanced.

The inclination angle θ3 of the _third ridge line with respect to the horizontal direction is preferably 30° or less, more preferably 20° or less, still more preferably 10° or less, and particularly preferably 0°. If the inclination angle θ3 is equal to or less than the upper limit _, the anti-slip effect and beautification effect in the height direction of the cap 1 are enhanced.

If the distance D is equal to or greater than the lower limit value, fingers are likely to be caught on the third ridgeline when gripping the gripping portion of the outer peripheral wall with fingers, and a slip prevention effect in the height direction is likely to be obtained.
The upper limit of the distance D may be appropriately set according to the height H of the cylindrical portion (height of the gripping portion).

The plurality of third ridgelines 26 in this example are formed at regular intervals in the height direction.
In addition, in the present invention, the third ridge lines do not have to be formed at regular intervals. In the present invention, it is preferable that a plurality of third ridge lines are formed at regular intervals from the viewpoint of a higher anti-slip effect and beautification effect.

The third ridge line in the cap of the present invention does not have to be formed so that fingers are always caught on the third ridge line at the moment the cap is gripped. Even if the finger is not caught on the third ridge line at the moment of gripping the cap, the finger slips slightly in the height direction when the cap is attached and detached, and the finger is caught on the third ridge line. Sliding in the direction is suppressed. In terms of minimizing the slippage of the fingers in the height direction of the cap and enhancing the beautifying effect, the number of the third ridges is within the range described above, and the third ridges are preferably formed at regular intervals. more preferred.

In the cap of the present invention, the inclination angle θ3 of the _third ridge line with respect to the horizontal direction is set to 0°, and the position of the third ridge line in the height direction of the upper part of the cylinder is aligned with the position for weighing the contents, The third ridge can also function as a scale. The aspect in which the third ridge line also functions as a scale for measurement is advantageous in that the liquid level of the contents can be easily visually recognized during measurement.

The outer peripheral wall 20 of the upper cylindrical portion 12 has a first triangular surface 32 and a second triangular surface surrounded by a first ridgeline 22, a second ridgeline 24, a third ridgeline 26 and a fourth ridgeline 28. 34 and a plurality of hexagonal faces 36 are formed. By forming such a plurality of polygonal surfaces on the outer peripheral wall 20, light is refracted and irregularly reflected in a complicated manner on the surface of the outer peripheral wall 20, so that a high beautifying effect can be obtained.

The first triangular face 32 is a triangle whose width in the circumferential direction of the upper tubular portion 12 increases as the distance from the canopy portion 14 increases. The second triangular surface 34 has a triangular shape in which the width in the circumferential direction of the upper cylinder portion 12 becomes narrower as the distance from the canopy portion 14 increases.
The hexagonal surface 36 is a concave surface that is recessed inward. The concave surface is not particularly limited as long as it is an inwardly concave surface.

If the number of polygonal faces is equal to or more than the lower limit of the above range, the anti-slip effect of the cap 1 in the turning direction and the height direction is enhanced. In addition, the beautifying effect due to light refraction and irregular reflection is enhanced. If the number of polygonal faces is equal to or less than the upper limit of the above range, the effect of preventing finger pain when gripping the cap 1 is enhanced. In addition, the size of each polygonal face is a suitable size that allows the shape to be visually recognized, and a higher design property can be obtained.

A plurality of scales (not shown) are formed on the upper cylindrical portion 12 to indicate the amount of contents contained in the cap main body 10 . Each scale consists of a measurement line indicating the distance from the canopy portion 14 to the lower cylinder portion 16, a number, and a unit indicating capacity. The scale includes, for example, laser printing, printing formed by printing (silk screen printing, tampo printing, etc.), convex stripes or concave stripes, and the like.

The threaded portion 40 includes a flange portion 42 projecting outward from the lower end of the upper tubular portion 12, and an axial direction of the upper tubular portion 12 extending from the peripheral edge of the flange portion 42 to the opposite side of the upper tubular portion 12. It has an outer cylindrical portion 44 coaxial with the cap main body 10 .

A threaded portion (not shown) that is screwed with a threaded portion of the container body is formed on the inner peripheral wall of the outer cylindrical portion 44 .
On the outer peripheral wall of the outer cylinder part 44, a knurled part 46 in which a plurality of ridges extending in the axial direction of the upper cylinder part 12 are arranged in the circumferential direction, and a ridge adjacent to the knurled part 46 are formed. A smooth portion 48 that is not flattened is formed.

By gripping the gripping portion 20a on the outer peripheral wall 20 of the upper cylindrical portion 12 with fingers and rotating the cap 1 about the axis, the threaded portion 40 is attached to the mouth portion of the container body (not shown). The cap 1 can be screwed on or off.
When measuring the contents, the cap 1 is screwed off from the container body, the contents are poured out from the container body, and the poured contents are poured into the cap body 10 from the open end of the lower cylinder part 16. - 特許庁At this time, by gripping the threaded portion 40 so as not to block the upper cylindrical portion 12 with the scale, the scale can be compared with the contents. At this time, by bringing the finger into contact with the knurled portion 46, the slippage of the finger is suppressed, and the contents can be weighed without dropping the cap 1. - 特許庁

It is preferable that at least the upper cylindrical portion 12 of the cap 1 is transparent, and the entirety is transparent, because the content poured into the cap 1 is easy to see and the beautification effect due to refraction and irregular reflection of light is high. is more preferable. Note that the cap 1 does not have to be transparent, because the beautifying effect of irregular reflection can be obtained even if the cap 1 is not transparent.

Materials for the cap 1 include polyolefin (polyethylene, polypropylene, etc.), polyester (polyethylene terephthalate, etc.), polystyrene, and the like. The cap 1 may be made of one material or two or more materials.
A method for manufacturing the cap 1 is not particularly limited, and injection molding may be used, for example.

As described above, in the cap 1, the first ridgeline 22, the second ridgeline 24, and the third ridgeline 26 are formed on the grip portion 20a of the outer peripheral wall 20 of the upper cylindrical portion 12, thereby forming a plurality of ridgelines. A first triangular face 32, a second triangular face 34 and a hexagonal face 36 are formed. Therefore, when the cap 1 is attached and detached, the anti-slip effect can be obtained in the rotation direction and the height direction, and the beautification effect is high, and the design is excellent.

The second triangular surface 34</b>A has a triangular shape in which the width in the circumferential direction of the upper cylindrical portion 12 becomes narrower as the distance from the canopy portion 14 increases.
The shape and size of the plurality of first triangular faces 32A and second triangular faces 34A may be the same or different, but are preferably the same from the viewpoint of a higher beautifying effect. .

A first triangular surface 32A and a second triangular surface 34A above and below the third valley line 26A are shaped to sink toward the third valley line 26A.
In this example, the first triangular surface 32A is substantially along the axial direction of the upper tubular portion 12, and the second triangular surface 34A is inclined with respect to the axial direction of the upper tubular portion 12.

In the cap of the present invention, the first ridge line and the second ridge line do not have to intersect at the holding portion of the outer peripheral wall of the cylindrical portion. For example, the cap of the present invention may be the cap 3 illustrated in Figures 7-9.
FIG. 7 is a perspective view showing a third embodiment of the cap of the present invention; FIG. 8 is a plan view of the cap of the third embodiment. FIG. 9 is a front view of the cap of the third embodiment. 7 to 9 that are the same as those in FIGS. 1 to 3 are denoted by the same reference numerals, and description thereof will be omitted.

The cap 3 is integrally formed with a cap main body 10B and a threaded portion 40 extending outward from the outer wall surface of the cap main body 10B.

The cap body 10B has the same aspect as the cap body 10 in the cap 1 except for the points described below.
In the cap main body 10B, the first ridgeline 22 and the second ridgeline 24 do not cross each other. The first ridgeline 22 and the second ridgeline 24 are formed alternately in the circumferential direction of the outer peripheral wall 20 of the upper tubular portion 12 .

As a result, slippage of fingers in the rotation direction and height direction of the cap 3 is suppressed when the cap 3 is attached and detached. In addition, since the outer peripheral wall 20 is formed with a plurality of first trapezoidal surfaces 38A and second trapezoidal surfaces 38B, the beautifying effect is high and the design is excellent.

In the present invention, like the caps 1 and 2, it is preferable that the first ridge line and the second ridge line intersect at the holding portion of the outer peripheral wall of the cylindrical portion. As a result, more ridge lines and valley lines can be provided, and the number of polygonal surfaces that can be formed on the outer peripheral wall of the cylindrical portion is increased, thereby enhancing the anti-slip effect and beautification effect.
