Description

  The present invention relates to a protective film with an adhesive and a separator for protecting a liquid crystal screen and the like.

  According to the conventional technical idea, when a user attaches a protective film with an adhesive to protect the LCD screen, etc., it is necessary to attach it accurately according to the size of the LCD screen. Setting was difficult.

  This invention makes it a subject to make easy the setting of a sticking position and the sticking operation | work at the time of sticking a protective film with an adhesive material on a liquid crystal screen etc.

  The present invention uses a uniaxially stretched film for the separator that protects the adhesive layer surface of the protective film with an adhesive material, and by providing an adhesive layer on the separator itself, the separator can be partially torn and peeled to allow partial exposure of the adhesive layer. This solves the problem of facilitating the setting and pasting work of a pasting position on a liquid crystal screen or the like.

  The protective film with an adhesive material and the separator of the present invention use a uniaxially stretched film as a separator, and the separator is also provided with an adhesive material layer. Therefore, a release sheet is applied to the separator adhesive material to form a three-layer film structure. The user peels off the lowermost release sheet and attaches the separator with adhesive to the correct position while finely adjusting the liquid crystal screen or the like. Since the separator with the adhesive material finished in this way uses a uniaxially stretched film, the separator with the adhesive material is torn and partially peeled off from the protective film.

  At this time, dust adheres to the adhesive material surface of the separator and is removed. Next, the adhesive-attached separator remaining after tearing is peeled off from the protective film. The positional relationship between the protective film and the liquid crystal screen is maintained by the operation of tearing and leaving a part. In this way, by adding a separator with an adhesive material using a uniaxially stretched film between the protective film with an adhesive material and the release sheet, dust adhesion is prevented when attaching the protective film with an adhesive material, and easy and accurate positioning is achieved. It becomes possible to do.

It is sectional drawing of a protective film with an adhesive separator. It is a top view of a protective film with an adhesive separator. It is sectional drawing of the state which affixed the paste surface of the separator on the screen. It is sectional drawing of the state which tears off a separator. It is sectional drawing of the state in which the separator was torn and a part remained. It is sectional drawing of the state which has peeled the remaining separator. It is sectional drawing of the state in which the protective film was stuck on the screen. It is an overhead view of the method of sticking a protective film.

  The separator material to be applied to protect the adhesive material on the adhesive surface of the protective film aligned with the LCD screen is a uniaxially stretched film, and the separator itself is also the adhesive material on the opposite side of the protective film adhesive surface. And the layer. A release sheet is applied to the opposite surface of the pressure-sensitive adhesive layer of the separator with the pressure-sensitive adhesive to protect it from dirt.

  Embodiments will be described below with reference to the accompanying drawings. FIG. 1 is a cross-sectional view of a protective film with a separator with an adhesive using the uniaxially stretched film of the present invention. Reference numeral 1 denotes a protective film, 1a denotes an adhesive layer, 2 denotes a separator using a uniaxially stretched film, and 2a denotes an adhesive layer of the separator. 3 shows the peeling sheet stuck on the adhesive material surface of a separator. FIG. 2 is a plan view showing a configuration of a protective film, a separator with an adhesive material, and a release sheet. 2b shows the tear guide used as the trigger which tears a uniaxially stretched film.

  FIG. 3 is a cross-sectional view showing a state in which the release sheet 3 is peeled off in order to attach the protective film to the liquid crystal screen, and the adhesive material surface of the separator 2 using the uniaxially stretched film with the adhesive material is attached to the liquid crystal screen. In this state, the positional relationship between the protective film and the liquid crystal screen to be protected is finely adjusted. Even if some dust remains on the LCD screen, it does not matter.

  FIG. 4 is a cross-sectional view of a state in which the separator 2 using the uniaxially stretched film with the adhesive material is torn off from the protective film 1 from the tear guide 2b. The protective film 1 is maintained in the positional relationship with the liquid crystal screen because the portion 2 left after the separator with the adhesive material is cut off is adhered to the liquid crystal screen. When the separator is torn off and peeled off from the protective film 1 and the liquid crystal screen 9, the dust on the surface of the liquid crystal screen 5 adheres to the adhesive layer 2a and moves.

  FIG. 5 shows a state in which the half surface of the protective film 1 is stuck on the liquid crystal screen 5. In this state, the portion of the separator with adhesive 2 that has been torn off still remains on the liquid crystal screen 5. FIG. 6 shows a state where the remaining separator 2 is peeled off. FIG. 7 is a cross section in a finished state in which the separator 2 using the uniaxially stretched film with an adhesive material is completely peeled off and the protective film 1 is stuck on the liquid crystal screen 5.

  FIG. 8 is an overhead view of the state in which the separator 2 is peeled off from the protective film 1 and attached to the liquid crystal screen 5.
