Disclosed herein is a screen protector assembly and a screen protector applicator comprising a screen protector assembly and an applicator tray, the screen protector assembly comprising a cover layer, a screen protector layer and a retention layer, wherein: the cover layer is bonded on a first side of the screen protector layer by a first glue layer provided on the screen protector layer; the retention layer is bonded on a second side of the screen protector by a second glue layer provided on the retention layer; and an interlayer is provided between the retention layer and the screen protector layer. The screen protector applicator has a simple structure, and can store and protect the screen protector assembly before application of the screen protector layer to the screen. In the process of screen protector application, the operation method is simple and convenient.

Systems and films for protecting surfaces of various substrates, including electronic devices, such as portable electronic devices, include a liner with a strip liner and a main liner. The strip liner, which covers a small strip of adhesive on the back side of a protective film, is configured to be removed before the main liner. With the small strip of adhesive exposed, the protective film may be aligned with a substrate and, if necessary, removed from the substrates and repositioned thereon. Thereafter, the main liner may be removed to enable complete application of the protective film to the substrate. Methods for securing protective films to substrates are also disclosed.

Disclosed is a protective film, which includes: a protective film sheet; a protective layer; and a release layer, a lead tab is connected to an end part of the release layer, and a positioning mechanism is arranged on the protective layer to align the protective film sheet with a screen of an electronic device.

Disclosed are a film pasting method and apparatus. The method includes: providing a protective film sheet, an electronic device and a push mechanism; aligning the protective film sheet with a screen; moving the push mechanism from a first side to a second side so as to sequentially paste the protective film sheet on the screen correspondingly. During a process of film pasting, an area where the protective film sheet is pasted with the screen defines a contact boundary proximate to the second side, the protective film sheet enters an exhaust state when the contact boundary moves, a contact angle is formed between a connection face which is formed by the contact boundary and the second side, and the screen, the contact angle gradually decreases along a moving direction of the contact boundary.

A resin metal composite body including a resin member containing a resin molding material containing a resin mixture (a1) and an inorganic filler (a2), and a metal member, and a test specimen of the resin mixture (a1) has a stress-strain curve in a tensile test according to ISO 527-1,2:2012 having a yield point, and a tensile yield stress of 25 MPa or more.

A resin metal composite body including a resin member and a metal member, the resin member contains a resin mixture containing a styrene-based resin composition, and a glass filler, the glass filler being 13.0% by mass or more and 37.0% by mass or less based on the resin mixture and the glass filler as 100% by mass, and the styrene-based resin composition contains a styrene-based polymer having a syndiotactic structure, a rubber-like elastomer, and an acid-modified polyphenylene ether, a content of the styrene-based polymer of 62.0% by mass or more and 85.0% by mass or less, a content of the rubber-like elastomer of 12.0% by mass or more and 37.0% by mass or less, and a content of the acid-modified polyphenylene ether of 0.1% by mass or more and 3.9% by mass or less, based on the styrene-based resin composition as 100% by mass.

According to the utility model, there is provided a film laminator for cell phones, useful for film lamination on a surface of a cell phone, including: a cell phone fixing plate, on which a through hole for receiving the cell phone is established, and a top surface of which is a horizontal face; with at least one position limiting plate for abutting the cell phone within the through hole being also fixed on the top surface. The film laminator for cell phones further includes: a film laminating plate for fixing a cell phone film; one end of which is hinged to the cell phone fixing plate, and the other end of which is movable freely so that the film laminating plate is bonded with the top surface of the cell phone fixing plate. With respect to the film laminator for cell phones according to the utility model, because the position limiting plate is provided on the cell phone fixing plate, the surface of the cell phone to which a film is to be attached can handily be kept in flush with the top surface of the cell phone fixing plate. Upon film lamination, the film laminating plate can contact with the top surface of the cell phone fixing plate and the surface of the cell phone to which a film is to be attached at the same time, so that the stress that is laid on it in the course of film lamination is very even, and a good effect of film lamination is obtained.

A screen protector laminate applicator is used with an installation machine to install a screen protector on a mobile device. The laminate applicator comprises a web secured to the installation machine; the screen protector carried by the web, and a backing layer covering the screen protector opposite the web. The web, the screen protector and the backing layer are removably coupled together as a laminate. A tab of the backing layer extends beyond the perimeter of the screen protector and comprises an enlarged head connected to the backing layer by a narrower neck.

A machine including an adjustable cradle configured to hold, individually at different times, electronic devices having different dimensions. The machine also can include an alignment base configured to engage, individually at different times, with alignment mechanisms of overlay applicators. Each respective one of the overlay applicators can include a respective overlay configured to be applied to a respective surface of each of the electronic devices. The machine can be configured to facilitate applying, individually at different times, the respective overlays to the respective surfaces of the electronic devices. Other embodiments are described.

Systems and apparatus for protecting a mobile device. The system includes a screen protector configured to be applied to a screen of the mobile device. The system also includes a cap configured to receive an end of the mobile device and prevent movement of the mobile device relative to the screen protector. The system also includes a pivot strip connecting the cap and the screen protector and being configured to facilitate a pivoting of the screen protector relative to the cap and establish alignment of the screen protector with the screen of the mobile device.
