1. Field of the Invention
This invention relates to a cleaner for display of mobile phone.
2. Description of the Related Art
Conventionally, a cleaner which has cloth for liquid crystal display of mobile (portable) phone has been used for cleaning of display (liquid crystal display) of mobile phone (refer to Japanese Utility Model No. 3093247 for example).
However, the conventional portable cleaner for liquid crystal display, used while attached to a strap of a mobile phone, has a disadvantage that motion of hand is restricted (by the strap) and cleaning is hindered thereby.
It is therefore an object of the present invention to provide a cleaner for display of mobile phone which can easily clean the display of mobile phone and be produced with low cost.
The present invention will be described with reference to the accompanying drawings in which:
Preferred embodiments of the present invention will now be described with reference to the accompanying drawings.
As shown in
Diameter d of fiber of the fiber cloth 1 is set to be 1 μm≦4 μm. In case of d<1 μm, the production of the cleaner becomes laborsome and causes high cost. And, in case of 4 μm<d, efficiency of wiping off the dust and oil stains is reduced. Thickness T1 of the fiber cloth 1 is set to be 250 μm≦T1≦350 μm. In case of T1<250 μm, the production of the cleaner becomes laborsome and causes high cost. And, in case of 350 μm<T1, wiping ability is not enhanced further, and efficiency is reduced. Cloths for cleaning eyeglasses produced by Kanebo Ltd. can be used as the fiber cloth 1.
The resin film 4 is composed, for example, of polyethylene terephthalate, Polyester, Polyvinyl, etc. The fiber cloth 1 can be made strong (reinforced against folding) by the resin film 4 even if the fiber cloth is soft and weak against folding. Thickness T4 of the resin film 4 is set to be 45 μm≦T4≦110 μm. When the thickness T4 is within the range above, the cleaner C has appropriate rigidity when bent, and the dust and oil stains on the display H of the mobile phone K (refer to
The pressure-sensitive adhesive layer 5 is composed, for example, of urethane system adhesive. Thickness T5 of the pressure-sensitive adhesive layer 5 is set to be 30 μm≦T5≦70 μm. When the thickness T5 is within the range above, appropriate adherence can be efficiently obtained. In case of T5<30 μm, the adherence may be low. And, in case of 110 μm<T5, the adherence is not enhanced further, and efficiency is reduced. The pressure-sensitive adhesive layer 5 is preferably ripened, for example, in a room kept at 80° C. for 10 days.
The released paper 6 is composed, for example, of silicone paper.
The present invention, modifiable in design, for example, may have a circular entire configuration. And, instead of the advertisement indicating portion 2, unique designs of art or names may be indicated.
As described above, with the present invention in which the reinforcing resin film 4 and the pressure-sensitive adhesive layer 5 for detachable attachment to the mobile phone main body K1 are serially layered on the reverse face 1b of the fiber cloth 1, a user can freely move the hand without restriction of hand movement by the length of the strap, and the display H of the mobile phone K is easily wiped with strength by the rigidity of the reinforcing resin film 4. Especially, appropriate rigidity is given even if the entire thickness is small. Even a small face can be well-polished for the rigidity. And, the cleaner can be compact to carry because the strap is unnecessary, namely, not to be an obstacle. The cleaner can be made with low cost for the simple construction. Further, when the fiber cloth 1 becomes dirty for use, wiping ability can be recovered by washing the fiber cloth 1. When the adherence of the pressure-sensitive adhesive layer 5 becomes weak, the adherence can be recovered by wiping the surface with a wet cloth or washing the layer with neutral detergent to remove the dust. And, dust and oil stains on glass, plastic, or metal can be easily wiped off.
And, appropriate rigidity can be obtained, and the display H of the mobile phone K can be easily wiped for easy handling because the resin film 4 is composed of polyethylene terephthalate, and thickness T4 of the resin film 4 is set to be 45 μm≦T4110 μm.
The cleaner is easy to handle and attached to the mobile Phone main body K1 as not to oversize the mobile phone main body K1 because entire configuration of the cleaner is of rectangle sheet, the longitudinal dimension L1 of the rectangle is set to be 25 mm≦L1≦35 mm, and the lateral dimension L2 of the rectangle is set to be 25 mm≦L2≦35 mm.
The cleaner is easily made and having high efficiency of wiping off the dust and oil stains because the diameter d of fiber of the fiber cloth 1 is set to be 1 μm≦d≦4 μm. And, advertisement is effectively directed to the user and people around the user because the advertisement indicating portion 2 of offset printing is on the obverse face 1a of the fiber cloth 1. And, the obverse face 1a of the fiber cloth 1 has no irregularity for good feeling in use.
While preferred embodiments of the present invention have been described in this specification, it is to be understood that the invention is illustrative and not restrictive, because various changes are possible within the spirit and indispensable features.
