Definitions

  • the present invention relates to a combination of an applicator and a screen protector to be applied a portable electronic device with a screen.
  • Such devices include tablets, smartphones and e-readers.
  • Screen protectors are available for such devices in the form of a screen protecting film of protective transparent plastics or glass material and an adhesive layer allowing the screen protecting film to be stuck to the screen. It is difficult to correctly align the screen protecting film with the device. This is important not only for the appearance of the device, but also to ensure various components which are exposed on the screen side of the device such as speakers, microphones, camera lenses, light sensors, fingerprint readers and face recognition sensors are not obstructed by the screen protector. Often it can take more than one attempt for a user to correctly align the screen protecting film which results in excess dirt building up on the adhesive layer, degradation of the adhesive layer and, in many cases, the screen protecting film will have to be thrown away.
  • screen protecting film defines the physical properties of the layer. It does not convey any limitations on the material used. This may be any known material used for screen protection or any other suitable material. Such materials are commonly transparent plastic or glass.
  • a second such device is manufactured by PureTEK as the“Roll-on KitTM”.
  • This device comprises a tray into which the device is placed so as to be in the correct alignment.
  • the screen protector is attached to the tray at one edge and the film supported only at this edge is progressively attached to the screen.
  • a roller is provided at one end of the tray which, following the removal of the backing material from the screen protector is rolled across the surface of the device in order to apply the screen protecting film to the screen.
  • a problem that these two applicators have in common is that, because the screen protector is attached only to one end of the frame, the application of the screen protecting film to the screen requires manipulation of a flexible component which is only attached via one edge.
  • a backing layer In order to attach the screen protecting film, a backing layer first needs to be removed from its adhesive surface. Because this requires the screen protector to be lifted away from the frame and the backing material peeled off, this is an awkward procedure. While backing material is being removed from the generally unsupported flexible layer, it is easily possible for a user’s hands to come into contact with the adhesive layer thereby introducing dirt onto the adhesive side of the screen protecting film. Further, once the backing layer has been removed, the adhesive layer of the screen protecting film then needs to be progressively pushed onto the screen.
  • US 2013/0020005 discloses an applicator to which a screen protector is stuck prior to application. A user then aligns the applicator via a projection on the applicator which engages with a socket in the device. Once in place, pressure on the applicator deflects part of the applicator such that the screen protector is applied to the screen. There is a problem in that the backing material is removed from the screen protector prior to engagement between the applicator and the device. The direction of application of the applicator is such that the screen protector needs to be in very close proximity to the screen as it is effectively moved across the face of the device. This provides ample opportunity for it to catch on the screen before it has reached the correct location.
  • a further device that we aware of is an applicator provided by Gadget Guard (no further details are available at the time of writing).
  • This is an applicator which is provided separately from the screen protector.
  • the applicator is in the form of a frame which is designed to fit around the mobile device.
  • the screen protector is placed into the frame by the end user and the release layer covering the adhesive on the screen protecting film is removed.
  • the frame is then placed over the device and pressure is applied directly to the screen protecting film to press it onto the screen. Because the screen protector is assembled by the user into the frame, it can be applied in the wrong orientation or not fully applied in the correct position This may only be apparent to the user after they have removed the release layer in which case if it is very difficult to realign the film without contacting the adhesive.
  • the frame itself covers part of the surface of the screen protector and pressure cannot be applied across the full face of the screen protector. This is particularly important to a device having a screen with curved edges as the screen protecting film needs to be applied to the screen at the curved edges.
  • a number of other applicators are known which are designed to engage with the edge of the mobile device such that they provide an alignment edge on the face of the device. Such an applicator is disclosed, for example, in W02015/101770. Such applicators only provide an alignment edge and there is otherwise no interaction between the screen protector and the applicator.
  • the approach taken by the present invention is to provide a second release layer which is attached at a plurality of discrete locations on opposing sides of the frame.
  • the screen protector is supported above the screen.
  • the user then holds the side of the frame and presses down on the second release layer in order to second release layer from the frame and, in the process, attach the screen protecting film to the screen.
  • the present invention applies the screen protecting film by pressing downwardly on the second release layer of which is supported on opposing sides of the frame.
  • the user is holding a release layer at a location perilously close to the adhesive on the screen protecting film and is constantly peeling off and applying the layer in a complex manipulation.
  • the screen protector is attached to the frame via the second release layer. This simplifies the assembly process and eliminates the possibility for misalignment or incorrect assembly of the screen protector into the frame. Because the screen protector is attached via the second release layer rather than being an interference fit inside the frame as in the Gadget Guard device, the present invention is not constrained to having a frame which encroaches across the face of the screen protecting film. As such, the present invention can make the whole surface of the screen protecting film available for the application of pressure. Such an arrangement is preferable particularly when the screen protecting film itself is flexible as the present invention will allow of the flexible film to be pressed down prior to the removal of the frame.
  • the releasable attachment between the second release layer and the frame may take the form of an adhesive attachment in which the adhesive between the second release layer and film is peeled away by the pressure on the second release layer.
  • the second release layer is releasably attached to the frame via a plurality of weakened portions on the second release layer. This allows the central part of the second release layer to be torn away from the frame upon the application of pressure on the second release layer.
  • the weakened portions may be in the form of score lines which extend through some but not all of the thickness of the second release layer. Alternatively or additionally there may be perforations which extend fully through the release layer but are intermittent in nature.
  • the second release layer may be attached to the frame by peripheral portions of the second release layer which are not removed with the screen protecting film being sandwiched between two components of the frame.
  • the second release layer is attached to the frame by peripheral portions of the second release layer which are not removed together with the screen protecting film being attached to a top surface of the frame. This allows the frame to be made as a one piece moulding.
  • This attachment may be via an adhesive attachment but is preferably an interference fit between a number of posts extending from the frame engaging the complimentary openings on the portions of the second release layer which are not removed with the screen protecting film.
  • the present invention also extends to a pack containing a combination of an applicator and a screen protector which are assembled together as well as a method of applying the screen protecting film as defined in claim 8.
  • Our intention is to supply the applicator and the screen protector together.
  • the screen protector may be supplied separately and can then be attachable to the frame, for example in a shop or repair centre which provides a screen protector fitting service.
  • the openings on the second release layer help to align and retain the second release layer on the frame.
  • the posts may be arranged asymmetrically such that the second release layer can only be attached in a single orientation. Under these circumstances, the present invention extends to a screen protector according to claim 1 1 .
  • Figs. 1 A to 1 H are a series of perspective views which show the application process with Fig. 1 A showing just the mobile and Figs. 1 B to 1 FI showing the frame; and
  • Fig. 2 is a plan view of the screen protector.
  • the combination according to the present invention comprises two main components namely a frame 1 and a screen protector 2 which are attached together as described below. Also shown in the drawings are a mobile device in the form of a smartphone P with a screen S.
  • the screen protector 2 comprises three separate layers namely a screen protecting film 3 as shown in Figs. 1 G and 1 FI as well as a first release layer 4 shown in Fig. 1 B and a second release layer 5 shown in Figs. 1 C to 1 G.
  • the screen protecting film 3 may be any known plastics or glass material and is preferably our Impact Shield (RTM) material.
  • the first and second release layers 4, 5 are PET.
  • the frame 1 is a hard rigid plastic such a polycarbonate, EPS, nylon or PET.
  • the screen protecting film has a layer of adhesive 6 on the side which initially faces the first release layer 4.
  • the second release layer 5 has a light adhesive to attach it to the screen protecting film 3.
  • the frame 1 generally has an open rectangular structure the inner dimensions of which are configured to closely match the dimensions of the mobile device. It is intended that a different frame 1 will be available to fit each type of mobile device should the dimensions differ.
  • the frame 1 shown in the drawings is designed to fit closely around all four sides of the smartphone P such that it cannot move laterally with respect to the frame 1.
  • the frame could engage only along a small part of each side or possible engage just with diametrically opposed corners of the smartphone P.
  • the frame 1 has a plurality of upstanding posts 7 spaced along the opposing longer sides of the frame 1.
  • the screen protector 2 is attached to these with a plurality of complimentary holes 8 in the second release layer 5 as best shown in Fig. 2.
  • the screen protector 2 is attached on the top surface of the frame via an interference fit between the posts 7 and holes 8.
  • the outer rectangle represents the perimeter of the second release layer 5.
  • This layer is provided with a central portion 9 flanked on either side by a pair of attachment portions 10 which extend longitudinally up the two long edges of the second release layer 5.
  • These attachment portions 10 include the holes 8 as described above.
  • a line of weakness 1 1 this takes the form of a cut line which extend through the entire depth of the second release layer 5.
  • the central portion 9 is attached to the attachment portions 10 only by a pair of attachment regions 12 where the cut line 1 1 is interrupted.
  • the number and spacing of the attachment regions 12 can be varied.
  • a score line could be provided rather than a through cut.
  • an adhesive tape or the like could be provided to attach the central portion 9 to the attachment portions 10.
  • cut lines 1 1 are shown running along the longer edges of the screen protector 2, they could alternatively run along the shorter edges.
  • the screen protecting film 3 which, as will be appreciated from Fig. 2 is spaced from the cut lines 1 1 . This allows pressure to be applied across the full area of the screen protecting film 3 whilst the frame 1 is in place on the smartphone P as describe below.
  • the smartphone P is one where the screen extends fully to the edge of the device, the outer periphery of the screen protecting film 3 is more or less the same as the outer periphery of the smartphone P.
  • the frame may be provided with a step 13 shown, for example, in Fig. 1 C extending along each of the longitudinal sides of the frame such that the width of the frame which engages with smartphone P is less than the width of the top of the frame between two rails 14 which support the second release layer 5.
  • the smartphone P is placed on a flat surface and the screen S is cleaned.
  • the frame 1 and screen protector 2 are preferably supplied pre-assembled to the user.
  • the first release layer 4 (which is shown in Fig. 1 B as being in two parts) is peeled away from the screen protecting film 3 to expose its adhesive surface 6.
  • the frame is then placed over the smartphone P as shown in Fig. 1 C until the frame 1 also rests on the surface.
  • the frame 1 and smartphone P are laterally aligned in two dimensions such that the screen protecting film 3 is correctly laterally positioned with respect to the screen S as it suspended a short distance above the screen S by virtue of the fact that the depth of the frame is greater than the depth of the smartphone P.
  • the user then applies downward pressure on the second release layer 5 either using a squeegee Q as shown in Fig.
  • FIG. 1 D some other flat edge or a finger.
  • This operation serves two purposes. Firstly, it severes the central portion 9 of the second release layer 5 from the attachment portions 10 and secondly it presses the screen protecting film 2 onto the screen S.
  • Fig. 1 D shows this operation partially complete with a central portion 9 being torn from the attachment portion 10 on the left hand side drawing but remaining attached on the right hand side of the drawing.
  • smartphone P is provided with curved edges.
  • the central portion 9 of the second release layer 5 is peeled away and the frame 1 as shown in Fig. 1 G and the frame 1 is lifted off of the smartphone P.
  • the frame 1 may be removed before the central portion 9 of the second release layer 5.
