A spectacle lens blank has an optically finished surface and a cylinder edge surface, and a protective film applied on the optically finished surface. The protective film is also arranged on the cylinder edge surface. A method for producing a spectacle lens from a spectacle lens blank having an optically finished surface and a cylinder edge surface, in which a protective film is applied onto the optically finished surface is also disclosed. Procedurally, the protective film is also applied onto the cylinder edge surface. Lastly, a device for producing a spectacle lens from a spectacle lens blank having an optically finished surface and a cylinder edge surface is disclosed, in which a protective film is applied onto the optically finished surface. An application unit for applying the protective film onto the cylinder edge surface is also disclosed.

Devices, methods and systems disclosed herein relate to the application of a protective film on a surface of an electronic device that instantly reduces air bubbles and eliminates the waiting time usually required when using a wet fluid solution. In one embodiment, a roller device may include a carriage or housing and one or more rollers coupled or integrated with the housing, configured to apply a protective material to a surface of the electronic device in a first orientation, and configured to function as a device stand in a second orientation. In addition or alternatively, a roller guide apparatus and/or a wedge may be utilized to assist the roller device in applying the protective material to the surface of the electronic device.

A portable film application apparatus includes a base, a positioning seat, a film holder, a conveyor and a film detaching device, wherein a positioning station and a film sticking station are provided on two sides of the base, respectively. The positioning seat is disposed at an end of the positioning station to lock the position of an electronic device. The film holder is disposed at an end of the film sticking station to lock the position of a film. The conveyor slides the positioning seat alternately between the positioning station and the film sticking station to match the electronic device with a membrane. The film detaching device is disposed at an end of the film sticking station to separate a release layer from the membrane.

A method for manufacturing a sanitary cover for a beverage can and relates to a technique for forming a cutting line along a circumferential surface of a sanitary cover while the sanitary cover is covering a beverage can, thereby maximizing the production efficiency of the sanitary cover having improved functionality. Also, the technique which, in three-dimensionally forming a cutting line as such, can carry out the process of forming the cutting line easily and rapidly via a simple structure, thereby increasing the production efficiency even further.

A device for installing a screen protector to an electronic device that includes a screen protector unit having a release film, a screen protector, and a protection film wherein the release film has a release tab, the protection film has at least one protection tab where the protection tab includes a hole formed therein; a tray having a panel, at least one alignment protrusion that fits the hole, a guide hole to allow external pressure to be applied onto the screen protector unit when the screen protector unit and the electronic device are received in the tray; and an adhesive strip, via the guide hole, further secures the screen protector unit to the tray. Also included is a method to using the device to install the screen protector to the screen of the electronic device.

A mobile phone screen protector device includes a positioning seat, a positioning frame, an auxiliary adhesive sheet, a screen protector, and a scraper. The positioning seat has a first raised portion, a second raised portion, and a positioning space between the first and second raised portions for accommodating a mobile phone with a screen facing upward. The first raised portion is higher than the second raised portion. The auxiliary adhesive sheet is adhered to an underside of the positioning frame. The screen protector is adhered to an underside of the auxiliary adhesive sheet. The positioning frame and the auxiliary adhesive sheet are confined to the tops of the first and second raised portions, and the screen protector is inclined at an angle relative to the screen. The scraper is pressed to scrape against the auxiliary adhesive sheet for the screen protector to be adhered to the screen.

A screen protector installation machine uses a screen protector laminate to apply a screen protector to a cell phone. The laminate comprise a web that carries the screen protector and a backing layer. The laminate is carried by a lid coupled to a base and closable over the base. An impression in the base receives the cell phone. A first slider is carried by the lid and comprises a spool rotatable with respect to the lid. A tab of the backing layer is coupled to the spool. As the slider slides over the cell phone, the spool rotates to wind the backing layer around the spool to expose the screen protector. The lid properly positions and orients the screen protector over the mobile device. The lid is automatically lowered onto the base, and the screen protector is automatically lowered onto the mobile device, by movement of the first slider after the backing layer is removed.
