Description

  The present invention relates to a protective film with an adhesive material that protects a device, a liquid crystal screen, or the like that is partially or entirely curved.

  According to the conventional technical idea, when a user attaches a protective film with an adhesive material for the purpose of protecting a device or a liquid crystal screen or the like partially or entirely composed of a curved surface, a cubic curved surface is provided by providing a cut in the film. There was a way to get away and paste the part.

  This invention makes it a subject to affix a protective film with an adhesive material on the apparatus or liquid crystal screen etc. by which the one part or all part was comprised by the curved surface.

  In this invention, a protective film comprising a protective film with an adhesive material and an adhesive layer surface protective separator is subjected to post-processing press to form a curved surface by using a mold or the like according to the outer shape and curved shape of the target device or liquid crystal screen. To solve the problem.

  Protective film with adhesive material that matches the shape of curved surfaces such as devices to be protected and liquid crystal screens increases the area to be protected, so it can protect a wider range of devices and liquid crystal display parts, and simultaneously protect the exterior parts of portable information terminals Thus, it is possible to provide the user with a sense of security when using the terminal.

It is sectional drawing of the protective film with an adhesive material in which all the parts were comprised by the curved surface. It is sectional drawing of the state which affixed the protective film with an adhesive material in which all parts were comprised by the curved surface to the liquid crystal screen etc. which all parts were comprised by the curved surface. It is sectional drawing of the protective film with an adhesive material in which one part was comprised by the curved surface. It is sectional drawing of the state which affixed the protective film with an adhesive material in which a part was comprised by the curved surface to the liquid crystal screen etc. in which a part was comprised by the curved surface. It is a bird's-eye view of the protective film with an adhesive material by which all the parts were comprised with the cubic curved surface. It is an overhead view of the state which affixed the protective film with an adhesive material in which all the parts were comprised by the cubic curved surface on the liquid crystal screen etc. which all the parts comprised by the cubic curved surface. It is sectional drawing of the protective film which all parts comprised by the curved surface and arranged the adhesive material in the outer peripheral part. It is sectional drawing of the state which affixed the protective film which arrange | positioned the adhesive material on the outer peripheral part to the liquid crystal screen etc. with which all parts were comprised by the curved surface, and arranged the adhesive material on the outer peripheral part. It is sectional drawing of the protective film which one part comprised by the curved surface and arranged the adhesive material in the strip | belt shape in the outer peripheral part. It is sectional drawing of the state which affixed the protective film which arrange | positioned the adhesive material in the strip | belt shape in the outer peripheral part in the liquid crystal screen etc. in which one part was comprised by the curved surface. It is a bird's-eye view of the protective film which one part comprised by the curved surface and has arrange | positioned the adhesive material to the outer peripheral part in strip | belt shape. It is a bird's-eye view of a state in which a protective film in which a part is formed of a curved surface and a band-like adhesive material is disposed on the outer peripheral portion is attached to a liquid crystal screen or the like that is partly formed of a curved surface.

  The protective film consisting of the protective film with adhesive and the adhesive layer surface protective separator is pre-curved to match the external shape and curved surface shape of the target device, so the user can simply peel off and apply the separator It is possible to protect the object.

  Embodiments will be described below with reference to the accompanying drawings. FIG. 1 is a cross-sectional view showing the shape of a protective film with an adhesive. 1 is a protective film with an adhesive material formed on a curved surface, 2 is an adhesive material, and 3 is a separator. FIG. 2 is a cross-sectional view showing a state in which the film is attached to a target device. FIG. 3 is a cross-sectional view of the protective film with an adhesive having an end formed into a curved surface. FIG. 4 is a cross-sectional view showing a state in which the film is attached to a target device. Conventionally, there is no idea of forming a protective film on a curved surface, and a stretchable film is stretched and pasted along the curved surface. FIG. 5 is an overhead view showing a film shape formed on a curved surface. FIG. 6 is an overhead view of a device to which the film is attached. The film is formed in a curved surface substantially matching the curved surface of the device to be attached.

  FIG. 7 is a cross-sectional view showing the shape of a protective film with an adhesive material that is formed in a curved surface and is provided with a belt-like adhesive layer 10 only at the end. 11 is a separator. FIG. 8 is a cross-sectional view showing a state in which the film is attached to a target device. The device 4 and the film 9 are fixed only by the belt-like adhesive layer 10 at the end. FIG. 9 is a cross-sectional view showing the shape of the protective film with an adhesive material in which the end portion is formed in a curved surface and the belt-like adhesive layer is provided only at the end portion. Reference numeral 12a denotes a flat portion of the film, and 12b denotes an end formed on a curved surface. Reference numeral 12c denotes a boundary between a plane and a curved surface. FIG. 10 is a cross-sectional view of the state in which the film 12 is attached to the target device 8.

  FIG. 11 is an overhead view showing the shape of the protective film with an adhesive material in which the ratio of the flat portion is large and the end portion is formed in a curved surface and the band-like adhesive layer 13 is provided only at the end portion. 12c shows the outline of the plane part of a film, 12d shows opening of an operation button. FIG. 12 is an overhead view of a state in which the film 12 is attached to the device 8.
