Abstract

PROBLEM TO BE SOLVED: To provide a cap which is excellently comfortable to touch with fingers and which can be smoothly rotated without the fingers slipping even if the cap is wetted with a solution such as a surface active agent, a detergent and a solvent. SOLUTION: The cap 1 has a thread 2 to be screwed with a container mouth on an inner peripheral surface wherein the cap is opened/closed by rotating in a circumferential direction of an outer peripheral surface of the cap. Vertical ribs 3 orthogonal to a rotating direction of the cap 1 are formed at predetermined intervals on the outer peripheral surface of the cap wherein a height T1 of the vertical rib 3 is in a range of 0.2 to 2.0 mm, while a distance W between adjacent ribs 3 and 3 is in a range of 0.5 to 20 mm. A small rib 4 lower than the vertical rib is formed between the adjacent vertical ribs 3 and 3 in parallel to the ribs 3.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap for a liquid container for storing a liquid agent such as a surfactant, a detergent and a solvent.

[0002]

2. Description of the Related Art A cap for a liquid container containing a liquid agent such as a surfactant, a detergent, and a solvent is rotated around the outer peripheral surface of the cap to prevent fingers from slipping when the cap is opened and closed. Vertical ribs (knurls) perpendicular to the direction are carved at regular intervals.

[0003]

However, in the case of a conventional cap, the vertical ribs are all at the same height, and when the cap is wet with a surfactant, a detergent, a solvent, or the like, even if the cap is turned, the fingers are turned. There was a problem that it could not be turned.

The present invention has been made to solve such a problem, and has excellent contact with a finger. Even when wet with a liquid such as a surfactant, a detergent or a solvent, the finger does not slip and smoothly. It is an object of the present invention to provide a cap that can be turned around.

[0005]

In order to achieve the above-mentioned object, the present invention has a screw portion which is screwed into a container mouth on an inner peripheral surface, and is rotated along a circumferential direction of an outer peripheral surface of a cap. In the cap which can be opened and closed by, a vertical rib perpendicular to the rotation direction of the cap is formed at predetermined intervals on the outer peripheral surface of the cap, and the height of the vertical rib is 0.2 mm.
To 2.0 mm, the interval between adjacent vertical ribs is set to 0.5 mm to 20 mm, and small ribs shorter than the vertical ribs are placed between the adjacent vertical ribs in parallel with the vertical ribs. It was formed.

In such a configuration, when the cap is turned, the surface of the finger between the vertical ribs comes into contact with the small ribs, and the frictional force increases. For this reason, even if the cap is wet with a surfactant, a detergent, a solvent, or the like, the finger does not slip, and the cap can be reliably turned.

Further, since small ribs exist between the vertical ribs, the flesh on the surface of the finger that has entered between the tall vertical ribs is supported by the small ribs. Therefore, the flesh of the finger surface does not enter deeply between the vertical ribs as in the related art, and the flesh of the finger surface that is fitted when the cap is turned with a strong force is twisted and the fingers are twisted. There is almost no pain.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. 1A and 1B show an embodiment of a cap according to the present invention. FIG. 1A is a plan view of the cap, FIG. 1B is a partially cut side view of the cap, and FIG. 1C is P _{1 in} FIG. It is an enlarged plan view of a part.

As shown in the figure, a cap 1 according to this embodiment has a screw portion 2 formed on an inner peripheral surface thereof for screwing to a container mouth, and a cap 1 of the cap 1 is formed on an outer peripheral surface of the cap. Vertical ribs 3 are formed at regular intervals in a direction perpendicular to the rotation direction. Further, small ribs 4 shorter than the vertical ribs 3 are formed between the tall vertical ribs 3 and 3, and the tall vertical ribs 3 and the short small ribs 4 are formed.
Are connected by a smooth curve, so that a large wave and a small wave are alternately repeated. Reference numeral 5 denotes a liquid-tight packing.

The height T ₁ of the tall vertical rib 3 is 0.2
mm to 2.0 mm, preferably 0.3 mm to 1.0 mm
And If it is less than 0.2 mm, fingers are less likely to be caught when opening and closing the cap 1, and the effect as a rib is lost.
If it exceeds 2.0 mm, the hand will hurt when the cap 1 is opened and closed, which is not preferable.

The interval W between the vertical ribs 3 is 0.5 mm.
２０20 mm, preferably 1.0 mm〜10 mm. If it is less than 0.5 mm, the interval is too narrow, and if it exceeds 2.0 mm, the finger is weakly caught when opening and closing the cap 1, and the effect as a rib is lost.

Further, when the height of the small ribs 4 is T ₂ , the ratio T ₁ / T ₂ to the height T ₁ of the vertical ribs 3 is 1.2 to 4, preferably 1.2 to 4. The height is set so as to be in the range of 1.2 to 2.5. The ratio is 1.2
If it is less than the height, the height difference is too small, the friction on the finger becomes small, and the finger becomes slippery. On the other hand, when the ratio exceeds 4, the height difference is too large, and the finger is hurt when the cap 1 is opened and closed.

The material of the cap 1 is not particularly limited, but when the cap is made of plastic, an olefin resin (PP, PE, etc.), polyester resin, acrylic resin or the like is used.

When the cap 1 of the above embodiment is used, similarly to the conventional cap, the cap 1 is gripped by the fingers at the vertical ribs 3 and the small ribs 4 on the outer peripheral surface of the cap.
May be screwed into the screw portion of the container mouth (not shown) or removed from the screw portion. At this time, as described above, the surface of the finger between the vertical ribs 3 comes into contact with the small ribs 4 and the frictional force increases, so that the cap 1 is wetted with a liquid such as a surfactant, a detergent, or a solvent. Even if you do, your fingers will not slip.

Further, since the small ribs 4 exist between the vertical ribs 3, the flesh on the surface of the finger which enters between the vertical ribs 3 is supported by hitting the small ribs. Therefore, the flesh of the finger surface deeply enters between the adjacent vertical ribs 3, 3 as in the related art, and the flesh of the finger surface fitted when the cap 1 is turned with a strong force is twisted. Almost no pain in your fingers.

In the above embodiment, the shapes of the vertical ribs 3 and the small ribs 4 are corrugated. However, the shapes of the vertical ribs 3 and the small ribs 4 are not limited to the waveforms. Trapezoidal shape with a radius at the corner (Fig. 2 (a)),
A rectangular shape with a radius at least at the corner on the tip side (Fig. 2
(B)), a mountain shape with a circular arc on the tip side (FIG. 2 (c)),
Further, other rib shapes such as a combination of these shapes can be adopted.

[0017]

EXAMPLE A bleach containing at least 5% of a surfactant was covered with a polypropylene cap (W = 1.6 mm, T ₁ = 0.48 m).
m, T ₁ / T ₂ = 1.6, rib shape: corrugated), filled into a container (material: PP), and evaluated the ease of opening and closing of the cap. It was confirmed that they could be opened and closed without any problems. Also, my fingers did not hurt.

[0018]

As described above, according to the present invention,
On the outer peripheral surface of the cap, vertical ribs are formed at predetermined intervals in a direction orthogonal to the rotation direction of the cap, and the height of the vertical ribs is set to 0.2.
mm to 2.0 mm, the interval between adjacent vertical ribs is set to 0.5 mm to 20 mm, and small ribs shorter than the vertical ribs are placed between adjacent vertical ribs in parallel with the vertical ribs. Since the cap is formed, it is possible to provide a cap which is excellent in contact with fingers and can be smoothly turned without slipping even when wet with a surfactant, a detergent or a solvent.
