Description of the invention (The present invention relates to a kind of protective and sealable transparent film, which is packaged in a protective closed container, and covers the screen. 1 Touch screen personal electronic device in Heyi Personal Electronics Devices such as handheld computers, mobile phones: people? Assistants are called game dresses, electronic music players, tweeters = Γ system (GPS), etc. 'have been reported in today's society. All aspects of life, including personal and filial piety, are practical. — Touch screens are usually used to enter the information I view. The advantage of touch screens is that only the display object or part of the screen is required to operate To make a selection or selection or turn-key investment in most environments, and especially in outdoor environments. 5 packs! Liquid, dust, food, grease, moisture and other dirty wood. Control screen pollution It adversely affects the operability of the personal wire. After being contaminated, these devices must be cleaned to expose the personal electronic device to harsh cleaning fluids, liquids and solutions again. It is necessary to operate properly in the environment, to protect sensitive electronic displays, closed containers with a watertight seal and a protective sealable transparent film are necessary. Conventional techniques have attempted to solve this problem in several ways. The problem is that 'a closed container with a touch screen front lid contains — or multiple gaskets' 'rings not only leak over time and exposure to environmental pollutants and cleaning fluids' but they must also Use additional assembly steps and: 'Add the (etc.) washer itself. The washer must be properly connected and installed, and this paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm') -4- 533128 A7 B7 V. Description of the invention (2) To perform its functions effectively, the use of these gaskets must have most operations and parts, which makes the manufacturing of the cover before using the gaskets very responsible. The ring is in a phase (please read the back first) Note: Please fill in this page again.) After a short time, leakage will occur due to the expansion and contraction of the gasket itself due to temperature changes in the environment. Other methods to solve this problem A closed container with an openable / closable protective puppet. These methods increase the chance of exposing the puppet to possible contaminants because they are not liquid-tight and must be opened to activate the touch screen. Not ideal. One example is disclosed in US Pat. No. 5,990,874 of a personal electronic device with a connectable openable / closable protective cover, in which the touchscreen is activated by depressing the protective cover when closed. Has limited ability 'Unfortunately, the cover does not provide a seal for the liquid order body and the components and the only function of the cover is to open or close the personal electronic device. Therefore, there is a need for a protective sealable Transparent elastic film with most touch screens enclosed in a protective closed container, and the touch screen can be actuated through the film, providing an effective waterproof and dustproof seal and protecting the touch screen from the environment And component effects. In addition, a step of assembling the number of parts and thus the cost can be reduced is also necessary. FIG. 1 is a perspective view showing the protective transparent elastic film. Fig. 2 is a perspective view showing the bottom side of the top of the protective transparent elastic film and the protective transparent elastic film embedded in one of the protective closed containers for personal electronic devices. Figure 3 is an exploded perspective view showing the protective transparent elastic film, the top of the protective closed container, a personal electronic device and the protective closure. This paper is sized to the Chinese National Standard (CNS) A4 (2K) x 297 mm. ) -5- Description of the invention (3) The docking bottom of the container. It is an object of the present invention to provide a protective elastic transparent film for use in embedded-personal electronic devices; a container that is compliantly closed and the touch screen can be seen through it. Another object of the present invention is to provide a protective sealable transparent elastic film 'which, when located in the protective closed container, provides protection and scratch resistance to the touch screen of the personal electronic device. Another purpose of the protective film is to provide a protective sealable transparent elastic 1 king film, which is located in the protective seal, especially the water tightness. When enclosed in M, a pair of liquids is provided. Another object of the present invention is to provide a protective sealable transparent elastic film which is located in the protective enclosed volume, especially the dust resistance. M. Speaking grains Another object of the present invention is to provide a kind of protective and sealable transparent bomb when touch two on the personal electronic device is actuated by the film. Another purpose is to provide a transparent elastic film that is easy to seal. Moreover, Wang Jzai: Another object of the invention is to provide a transparent elastic film which is easy to seal. m J?
