Abstract

PURPOSE:To prevent the temporal loss of the matte state of a matte glass bottle havng minute protrusions on the surface, caused by the sweat and grease of fingers, etc., by making the height of each protrusion high, and the areal density of the protrusions low. CONSTITUTION:A matte surface 3 is formed by forming minute protrusions 2 on the surface of a glass bottle 1 by the corrosion process with an agent such as hydrofluoric acid, ammonium fluoride, etc., or sand-blasting, glassbead-blasting, etc. In the above process, the height of each protrusion is made high, and the areal density of the protrusions is made low, e.g. by carrying out the matte processing under the condition to increase the etching roughness. The volume of the groove between the protrusions is made by this process to a level to prevent the plane connection of the tips of the protrusions 2 with sweat, etc. even if the sweat, etc. of finger, etc. is attached to the groove. The matte surface 3 is printed with a lustering paint 5, etc. to obtain the objective glass bottle.

Description

[Detailed description of the invention] The present invention relates to a glass layer with a matte surface.

Glass layers with matte surfaces formed by chemical corrosion, sandblasting, glass bead blasting, etc. have been widely used as containers for cosmetics and the like due to their excellent decorative effects.

However, these matte surfaces easily lose their matte state temporarily due to sweat, oil, etc. from fingers, etc., and the M part where sweat, oil, etc. are attached becomes transparent, and fingerprints etc. can be temporarily hidden on the surface. This has the disadvantage that it can cause the viewer to feel unclean.

Therefore, the present invention has been created to solve the above-mentioned disadvantages. By increasing the amount of protrusion of each protrusion and reducing the density of each protrusion, the capacity of the rows between the protrusions is reduced to prevent liquids such as sweat from fingers from adhering to the rows. This is because the capacitance is such that the tips of each protrusion are not connected in a flat state due to liquid such as sweat.

Furthermore, by applying glitter printing to the matte surface formed in this way, an even more brilliant printed surface appears on the matte surface, thereby providing a glass bottle with an excellent decorative effect that is full of interest. The gist of this is to create a glass bottle with a matte surface formed through chemical corrosion, sandblasting, glass bead blasting, etc. By making the protrusions larger and lowering the density of each protrusion, the capacitance of the rows between the protrusions is reduced so that fluids such as sweat from fingers may adhere to these rows and the tip of each protrusion is covered by this fluid. The matte surface formed in this way is printed with a glittering paint, and this printing is made by applying # paint to the open rows of each protrusion. The reason for this is that the amount of paint applied is such that the tip of each protrusion is not connected in a planar shape with this paint.

Embodiments of the present invention will be described below based on the drawings.

In the figure, 1 is a glass bottle, on the surface of which minute protrusions 2 are formed by corrosion processing with chemicals such as hydrofluoric acid and ammonia fluoride, sandblasting processing, glass bead blasting processing, etc., and the matte surface 3 get. This formation is performed by lowering the arrangement density of the protrusions 2 and increasing the amount of protrusion of each protrusion 2 than in the conventional matte surface 3 shown in FIG.

Specifically, the protrusions 2 are formed, for example, by intentionally etching the surface of the glass bottle 1 to a large extent.

The thus formed matte surface 3 is printed with glitter paint 5 (for example, gold or silver for J1 glass bottles) to obtain a satin-like printed surface. The amount of paint applied is such that the paint does not adhere to the parts and connect the tips of each protrusion 2 in a flat shape with this paint.Usually, the matte surface 3 is roughened as described above. In other words, liquid such as sweat from fingers 4 is applied to the row part of each protrusion 2.
The amount of protrusion of each protrusion 2 is increased and the density of each protrusion 2 is lowered in order to have a capacity of the row portion that will prevent the tips of the protrusions 2 from being attached and connected in a flat shape by liquid 4 such as sweat. Since the roughness is the same as that used for printing on glass surfaces, it is sufficient to apply a coating amount similar to that used for printing on glass surfaces.

As shown above, in a glass bottle with a matte surface formed by chemical corrosion processing, sandblasting processing, glass bead blasting processing, etc., the matte surface 3 is formed by increasing the protrusion amount of each protrusion 2, and Each protrusion 2 is formed with a low density to reduce the capacity of the row portion between each protrusion 2, so that liquid 4 such as finger sweat adheres to this row portion and the tip of each protrusion 2 is covered with liquid 4 such as sweat. Since the capacity is such that the glass bottle 1 does not connect in a flat shape, it has the disadvantage that conventional glass bottles 1 having a matte surface 3 have a problem, that is, the luster is easily deteriorated by liquids 4 such as sweat from fingers, oil, etc. It is possible to eliminate the inconvenience of temporarily losing the erased state and making the parts where sweat, oil, etc. adhere to become transparent, causing fingerprints and the like to appear temporarily on the surface, giving a feeling of uncleanness.

That is, as shown in FIGS. 1 and 2, the conventional matte surface 3 has a small amount of protrusion 2 and a high arrangement density of the protrusions 2, so that it easily absorbs liquids such as sweat and oil from fingers and the like. 4 adheres between the protrusions 2, the liquid 4 fills the rows between each protrusion 2, and the tips of each protrusion 2 are connected in a flat shape by the liquid 4 such as sweat and fat, resulting in a matte surface. Make 3 temporarily transparent. Since liquids 4 such as sweat and oil are deposited by hands and fingers, the transparent portions appear on the matte surface 3 as fingerprints. On the other hand, the matte surface 3 of the present invention is formed by increasing the protrusion amount of each protrusion 2 and reducing the density of each protrusion 2, so that sweat from fingers or the like 8124 is formed in the rows between the protrusions 2. Since the volume of the neck part was set so that the tip of each protrusion 2 would not be connected in a planar shape by this liquid 4, each protrusion 2
The capacity of the neck area between the matte surfaces 3 can be increased compared to the conventional one. Therefore, even if liquid 4 such as sweat or oil adheres to the neck area between each protrusion 2 of the matte surface 3, the neck area can be increased. This prevents liquids 4 such as sweat and oil from filling the part and connecting the tips of each protrusion 2 in a planar shape due to liquids 4 such as sweat and oil from the fingers. 4, the matte surface 3 no longer becomes temporarily transparent.

Therefore, the temporary appearance of fingerprints and the like on the matte surface is eliminated by the usual small amount of liquid 4 such as sweat and oil from the hands and fingers, and there is no longer any sense of uncleanness on the viewer.

In addition, the matte effect is not impaired in any way (it has an excellent decorative effect like the conventional one).

Furthermore, the matte surface formed in this way is printed with a glittering paint 5, and this printing causes the paint 5 to adhere to the neck portion of each protrusion 2, and the tip of each protrusion 2 to be flattened by the paint 5. Since the coating is applied in an amount such that the coating does not connect in a shape, the glitter coating 5 is attached to the surface of each protrusion 2 with a uniform thickness.

Therefore, the light reflected on the printing surface is diffusely reflected by each protrusion 2, and in addition to the brilliance caused by the white body of the glittering paint 5, this diffused reflection is further enhanced by the brilliance of iron, resulting in a glittering print. It is possible to make a surface appear on a matte surface.

As explained above, according to the present invention, it is possible to eliminate the disadvantages of conventional matte surfaces, that is, fingerprints and the like appear temporarily and give a feeling of uncleanness to the viewer. A glittering printed surface can be applied to the matte surface 3, and a glass bottle with excellent decorative effects can be provided.
