[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container used for body soap, hand soap, face wash, shampoo, rinse, hair dye, beverage, insecticide, etc. Non-slip technology.

[0002]

2. Description of the Related Art Conventionally, as a container for shampoo used in a bathroom or the like, there is a handy type container for operating a spout while holding the container with one hand. If such a container is held with a painted hand or a hand to which a soap component such as foam is attached, the hand is slippery and difficult to handle. For example, if the container is an aerosol can, it is necessary to hold the container and press the spray button of the spout, but at this time, the hand holding the container slips and force cannot be applied, so press the spray button. There was a problem that it was not or difficult to push.

Therefore, a container having an anti-slip function on the outer circumference of the container body has been conventionally proposed (Japanese Patent Laid-Open No. 10-1).
No. 52159). In this conventional container having a non-slip function, fine irregularities are formed by transparent matte printing or blasting in a printing area on the outer periphery of the container where a logo or a writing is written.

[0004]

However, in the above-mentioned conventional container with a non-slip function, the outer layer of the container is covered with a surface having fine irregularities, and as described in the above publication. However, there is a problem that the entire area provided with the unevenness becomes matte and the gloss is impaired. Therefore, in the conventional example, the fine unevenness is limited to the logo or the writing area, and there is a problem that the non-slip area is restricted to the printing area.

The present invention has been made to solve the above-mentioned problems of the prior art, and is a slip stopper capable of imparting an effective slip preventing function without impairing the surface condition such as gloss of the outermost layer of the container body. It is to provide a container with.

[0006]

In order to achieve the above object, according to the present invention, dot-shaped or linear-shaped anti-slip projections are scattered on the outermost layer of the container body to be gripped and used by hand. It is characterized in that it is provided in a shape. The outermost layer of the container body may be the upper surface of the printing layer. This is effective when the container body is provided with a pouring tool for pouring out the contents. The non-slip protrusions are formed of, for example, a resin attached to the outermost layer of the container body. Resin ink is used as resin,
It is preferable that the non-slip protrusions are formed by a printing technique. In particular, the printing technique is preferably screen printing, and the resin ink is preferably transparent ink. Further, the linear anti-slip portion may be configured by a character string or a line drawing.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below based on the illustrated embodiments. FIG. 1 shows a non-slip container according to an embodiment of the present invention. That is, the non-slip container 1 includes a container body 2 and a pouring tool 3 attached to the container body 2 for pouring out contents. The container body 2 is a metal can having a substantially cylindrical shape, and the outer periphery of the container can be grasped by hand and the pouring operation of the upper pour tool 3 can be performed. On the surface of the outermost layer of the container body 2, dot-shaped anti-slip protrusions 4 are formed.
Are provided in a scattered manner. The area in which the non-slip protrusions 4 are provided may be provided in an area where the container body 2 is gripped with fingers. In the case of an ordinary metal can, it has a cylindrical shape and has no particular directionality, and therefore it is preferably provided over the entire circumference. However, when the gripping direction is determined by the spouting tool 3 or the like, it may be provided only within the range where the fingers make contact.

The shape of the non-slip convex portion 4 is shown in FIG.
In (A), it has a spot-like round shape. Figure 1
As the diameter d and the height h shown in (B), appropriate values are selected according to the use of the can, the size and weight of the can, the friction coefficient of the can surface, the surface properties, the roughness, and the like. In particular, the height of the non-slip convex portion 4 varies depending on the surface condition, but it is preferable that the height is such that it can bite into a finger to some extent. The height h is preferably about 20 to 300 μm.
The spot-like shape (dot shape) of the anti-slip convex portion 4 is not limited to a circle, and various shapes such as a triangle, a square, and a polygon can be adopted. Further, the non-slip convex portion 4 can be formed in a linear shape instead of a dot shape. When making a line shape,
A character string such as a company name as shown in FIG. 1C and a line drawing such as a logo mark as shown in FIG. 1D can be used. As a character string, it is possible to display not only the company name but also various characters and symbols such as character trademarks, and as a line drawing,
It is also possible to display not only the logo mark but also a graphic trademark or the like to convey information or to give an effect as a decoration. The arrangement pattern of the non-slip protrusions 4 is, in the illustrated example,
Although they are arranged in a dotted pattern at a predetermined interval, the arrangement pattern is arbitrary. Characters, figures, patterns and the like can be arranged so as to be displayed by the arrangement pattern of the anti-slip convex portions 4.

FIG. 2A shows a sectional structure of the metal can. That is, a printing ink layer 22 (including a base treatment) is provided on the surface of the metal material 21, and a finishing varnish layer 23 is coated on the surface thereof as an outermost layer. On the surface of the finish varnish layer 23, the anti-slip protrusions 4 are provided. The non-slip protrusions 4 are made of resin ink as a resin that adheres to the finishing varnish layer 23. In this embodiment, the resin ink is transparent ink and is formed by screen printing. By using the transparent ink, the visibility of the printed display 5 below is not affected at all. However, it is not limited to colorless and transparent, and a transparent ink having a tint can be used, and an opaque colored ink to which a pigment is added can be used as long as it does not affect the print display of the lower layer.

As a printing method, a printing method other than the screen printing may be applied. However, when the screen printing is used, the resin ink is deposited on the surface of the printing object through the holes formed in the screen, Ink thickening is possible, which is suitable for the anti-slip projection 4 of the present invention. As a resin material of the resin ink, an acrylic resin, an epoxy resin, a melamine resin, a urethane resin or the like is preferable, although it depends on the material of the outermost layer. As a drying method, an ultraviolet curing type, an oxidative polymerization type or the like is used. Also,
The viscosity of the resin ink is a factor that affects the rising height of the non-slip convex portion 4, and is preferably set to about 50 to 450 poise. As the resin ink, a medium type without beads may be used, or a high friction type resin ink in which beads are added to the resin ink to increase friction may be used. 2 (B),
(C) shows the trace shapes of the anti-slip protrusions 4 formed by printing with medium type and high friction type resin inks in comparison. In the case of the medium type, the surface of the convex portion 4 is smooth (FIG. 2 (B)), whereas in the high friction type, the surface of the convex portion is rough (see FIG. 2 (C)), and the friction is increased.

In the above embodiment, a metal can is used as an example of the container, but the type of container is not limited to a can, and various types of containers such as bottles and cups can be used. Further, the material is not limited to metal, and can be applied to containers made of various materials such as glass, plastic, and ceramics. Further, the contents can be applied to various contents such as body soap, hand soap, face wash, shampoo, conditioner, hair dye and beverage.

EXAMPLES Table 1 shows the test results of the grip property evaluation. As the grip property evaluation, as shown in FIGS. 3A and 3B, a rubber ring 100 such as silicon rubber was used, and the pushing load of the inspected can 102 into the rubber ring 100 was measured. The outer circumference of the rubber ring 100 is fitted in the metal ring 101. The inner diameter D of the rubber ring 100 is φ48.55 mm, the inner diameter portion length L is 10 mm,
A portion (pushing amount: 20 m) where the non-slip convex forming region 103 of the inspected can 102 completely enters the ring land portion (corresponding to the inner peripheral surface of the rubber ring 100) of the rubber ring 100.
The load at m) was read.

As the cans 102 to be inspected, there were three types of cans W1, cans W2 and cans W3 having different types of anti-slip projections, and a conventional can W4 coated with a matte varnish was used as a comparative example. The coating range of the matte varnish was the same as the area provided with the anti-slip protrusions. Each of the cans W1, W2 and W3 was formed with a non-slip convex portion by screen printing using a resin ink, and the thickness including the photosensitive layer of the screen printing plate used for printing was 125 μm, 155μ
m, 185 μm was used. As a test, 10 cans of each type of indentation load were measured with the shampoo attached to the inspected can 102 and the rubber ring 100. The average load is shown in Table 1.

As shown in Table 1, the average load of the can with shampoo attached is 4.8 kgf in the conventional mat printing, whereas in the present invention, the photosensitive layer is used as the screen printing plate. In the case of the can W1 using the included plate having a thickness of 125 μm, the grip force was as large as 7.0 kgf. Further, an increase in gripping force was also observed in cans W2 and W3.

[0015]

As described above, according to the present invention, since the outermost layer of the container body is provided with the non-slip convex portion,
The grip force is increased, and slippage of the container body in a wet state can be prevented. In particular, since the anti-slip projections are provided on the surface of the outermost layer in a dot shape or a line shape, the outermost layer surface is exposed as it is in the area between the adjacent anti-slip projections, so It does not damage the surface condition. Therefore, the most effective part can be provided with the anti-slip function without being restricted by the printing area of the container body. Further, when the spout has the spout, the spout can be operated without slipping the container body even in a wet state.

Further, if the anti-slip projections are made of a resin that adheres to the outermost layer surface of the container body, the resin that rises from the outermost layer surface will appropriately bite into the finger and the grip strength can be improved. Using resin ink as resin,
If the non-slip projections are formed by a printing technique, it is easy to manufacture without requiring large-scale equipment introduction. In particular, the screen printing facilitates thickening of the resin ink and allows the anti-slip projections to have a sufficient thickness. Furthermore, if the resin ink is a transparent ink, it is possible to form the non-slip projections without impairing the visibility of the existing printing surface. By forming a linear anti-slip portion with a character string or a line drawing, it is possible to display information such as advertisements and to provide an effect as decoration.
