Hereinafter, a mobile device protective cover according to an embodiment of the present invention with reference to the accompanying drawings will be described in detail.

1 is an exploded perspective view showing a coupling relationship between a mobile device protective cover and a mobile phone according to an embodiment of the present invention, Figure 2 is a side cross-sectional view showing a layer structure of the mobile device protective cover shown in FIG.

As shown, the mobile phone cover 1 proposed by the present invention has an appropriate elastic force and can be protected by being coupled to the mobile phone 3.

That is, the mobile device protective cover 1 has a structure that is covered on both sides of the mobile phone (3).

The mobile device protective cover 1 having such a structure includes: a base layer 5 mixed with a synthetic resin, a functional resin, and a perfume; The soft synthetic resin and the functional resin are mixed and composed of a soft layer 7 coated on the outside of the hard layer 5.

In the rigid layer 5, the rigid synthetic resin may include all synthetic resins having rigidity, but preferably includes polycarbonate (PC).

This rigid synthetic resin allows the protective cover to maintain a certain strength.

In addition, the functional resin performs an antibacterial, sterilizing, deodorizing function. These functional resins can be mixed in powder or liquid form and include tourmaline, metals, mineral minerals, charcoal, ganbanite, vernedium, germanium, and bamboo vinegar.

Functional resin composed of these components is based on 100 parts by weight of rigid synthetic resin 0.2-75 parts by weight of tourmaline, 0.05-10 parts by weight of metal, 0.1-45 parts by weight of mineral minerals, 0.1-25 parts by weight of charcoal, 0.1-55 parts by weight of elvan 0.3 to 35 parts by weight of benedium, 0.1 to 35 parts by weight of germanium, and 0.0001 to 1 part by weight of perfume.

In the above-mentioned functional resin, the metal means a component of any one of copper, gold, platinum, silver, and titanium dioxide.

In addition, the metal component is usually 300nm or less in diameter, in the case of improving the antibacterial, sterilization, deodorizing ability is used to mix the nanoparticles of 200nm or less in powder or colloidal state.

When the metal component is less than 0.05 parts by weight, it is difficult to exhibit the antibacterial and deodorizing functions quickly. When the metal component is more than 10 parts by weight, the reactivity of the ions and the like is too high, causing color reactions, and discoloration may occur remarkably when applied to the resin composition. There is concern.

In addition, the charcoal preferably includes bamboo charcoal and performs a deodorizing function due to the antimicrobial properties of the bamboo and the porosity of the charcoal. Such bamboo charcoal may be used in the form of powder prepared in the form of particles.

When the bamboo charcoal is less than 0.1 part by weight, it is difficult to obtain sufficient deodorization, and when it exceeds 25 parts by weight, it may cause a problem in coloring or formability.

The mineral mineral preferably includes earthenware. These mineral minerals contain more than 40 kinds of mineral elements, and are excellent in improving water quality such as various minerals eluting, adjusting pH, increasing dissolved oxygen, and emitting highly efficient far infrared rays.

If the mineral mineral is less than 0.1 part by weight, the adsorption performance is not expressed, and if it is more than 45 parts by weight, the compatibility with the resin is reduced, the molding workability is lowered.

The tourmaline preferably means tourmaline. Such tourmaline is a polar crystal, and a microcurrent flows and is piezoelectric, and thus has an antistatic function.

When the tourmaline is less than 0.2 parts by weight, it is difficult to sustain the expression of far infrared rays due to the weak electrical performance, and exceeds 75 parts by weight, there is no performance improvement effect as much as exceeded.

The elvan has good antibacterial and deodorizing properties by adsorbing bacteria by silicon monoxide radicals and adsorbing surrounding odor particles.

If the above-mentioned elvan is less than 0.1 part by weight, the effect of elvan is insignificant, and if it is more than 55 parts by weight, miscibility with the resin is lowered and dispersion becomes difficult.

Bernesedium has a far-infrared radiation effect, and may be contained in the ceramic powder to increase the amount of negative ions generated. If it is less than 0.3 part by weight, such an ions will decrease the effect of generating negative ions, and if it exceeds 35 parts by weight, the dispersibility with resin will decrease.

The germanium generates a synergistic effect of far-infrared radiation and anion generation. If the germanium is less than 0.1 part by weight, the far-infrared radiation effect is lowered, and if it exceeds 35 parts by weight, there is no effect as much as the excess.

In addition, the fragrance may emit various scents. At this time, the fragrance includes a variety of fragrance components, such as fruit flavor, flower flavor, plant flavor, herbal flavor, perfume, coffee flavor, chocolate flavor, fruit flavor.

In addition, by containing bamboo vinegar, if necessary, the functional resin can also improve sterilization and antibacterial function.

Further, the mixing ratio of the rigid synthetic resin and the functional resin preferably includes 10-15 g of the functional resin in 1000 g of the rigid synthetic resin.

On the other hand, the soft layer may be coated on the outside of the rigid layer (5). The soft layer 7 has a configuration similar to that of the hard layer 5, but the soft synthetic resin is mixed in place of the hard synthetic resin. That is, the soft layer is a mixture of soft synthetic resin and functional resin.

The soft synthetic resin may include all synthetic resins having ductility, but preferably includes any one of elastomer, polyethylene (PE), and polyurethane (PU).

The functional resin has the same components and proportions as the functional resin contained in the rigid layer 5.

That is, the functional resin is based on 100 parts by weight of soft synthetic resin 0.2 ~ 75 parts by weight of tourmaline, 0.05 ~ 10 parts by weight of metal, mineral minerals 0.1 ~ 45 parts by weight, charcoal 0.1 ~ 25 parts by weight, elvan 0.1 ~ 55 parts by weight, burner It is mixed in the proportion of 0.3 to 35 parts by weight of sodium, 0.1 to 35 parts by weight of germanium, and 0.0001 to 1 part by weight of perfume.

Therefore, the soft layer 7 is formed outside the rigid layer 5 to exert an elastic force to protect the mobile device from external shock or vibration.

On the other hand, in the above, the rigid layer and the soft layer of the protective cover has been described as a structure formed in the inner and outer direction, the present invention is not limited to this, as shown in Figure 3, the rigid side 5 and the soft layer ( 7) may be disposed in the front and rear direction along the longitudinal direction of the edge of the protective cover (1).

That is, the soft layer 7 is disposed in the front direction a1 (upper direction; the direction in which the front surface of the mobile device is located) with respect to the border line L, and the rigid layer 5 is in the rear direction a2 (lower direction). The direction in which the rear side of the mobile device is located.

Therefore, the part in which the rigid layer 5 is formed maintains the shape of the protective cover, and the part in which the soft layer 7 is formed is flexible, so that the mobile device can be easily coupled.

That is, as shown in Figure 4, the protective cover 10 has a structure that can cover the back of the mobile device by forming the plate 14 as well as the edge 12 of the mobile device. In this case, the protective cover 10 may be easily coupled to or separated from the mobile device by placing the rigid side 5 and the soft layer 7 in the front and rear directions along the length direction of the edge of the protective cover 1. have.

At this time, since the rigid side 5 and the soft layer 7 may be made of the same components as described in the previous embodiment, a detailed description thereof will be omitted below.

On the other hand, such a protective cover may be made of only a soft layer. That is, the protective cover may be made of a hard layer and a soft layer, but may be made of only the soft layer as shown in FIG. 5.

The protective cover 10 has a structure that can cover not only the edge 12 of the mobile device but also the entire front part and the rear part 14. In this case, the protective cover 10 may be made of a soft material to easily wrap the outside of the mobile device.

When the protective cover 10 is made of only a soft layer, the protective cover 10 may be manufactured by mixing a soft synthetic resin and a functional resin at a predetermined ratio.

In this case, the soft synthetic resin may include any one of elastomer, polyethylene (PE), and polyurethane (PU) as in the above embodiments.

In addition, the components and the synthesis ratio of the functional resin may be prepared in the same manner as in the previous embodiment.
