Description

Flexible impact protection box, method of manufacturing the same, and method of use Related applications

This application is a partial continuation of the co-ownership and joint trial application No. 13/271,594 filed on October 12, 2011, and claims US Provisional Application No. 61/556,749, filed on November 7, 2011. The benefits of both applications are hereby incorporated by reference in their entirety.

This disclosure relates to a flexible impact protection box and a method of manufacturing the same.

A protective case for a sensitive device, device or tool is typically designed with a filler on the interior or exterior, or both, which is protected multiple times by materials such as synthetic rubber, foam and/or layered materials and the like. A continuous sheet of material is formed. These cases usually do not provide adequate protection from shocks, vibrations, and the like. Protection for such devices can be improved by the use of thicker materials, but increasing the thickness can be undesirable due to the increased volume or weight. Furthermore, the increased weight and volume may be undesirable for streamlined electronic devices, for which the users typically pay a bonus to obtain an elongated and/or lightweight product.

Many electronic devices have a screen interface that is used to display information to the user, so it is necessary to expose the screen during use. However, the screen interface is known to be fragile and tends to break easily when dropped or otherwise impacted.

Portable electronic devices, such as laptops, or medical devices, also have a screen interface, and to protect the screen interface, the device typically includes a hinged protective cover that provides some protection while not It is free from falling or impact when in use. However, many mobile phones, media devices, and tablet-type computers or small notebooks do not include such covers. Thus, a screen or edge impact can easily cause severe damage to the screen and/or device. In addition, some devices, such as the iPad device, are thin and fragile, which deteriorates their ability to withstand impact. As a result, many companies now manufacture cover pieces, protective cases, and housings that can be purchased separately from such devices, which tend to fall into a number of different categories.

One type of protective case is a rigid plastic housing that may contain internal or external fillers such as rubber or polyoxyalkylene. While these rigid housings provide some protection, there are some disadvantages. First, the housings are made for a particular device size and configuration, and thus cannot be used with "next generation" devices, such as when a device is updated or changed. The store must also stock most inventory units of measure ("SKU(s)") to accommodate even a similar range of devices. Another disadvantage is that these rigid housings, even with some soft additional components, do not protect well from the face or the opening of the screen. Even devices that contain a protective bezel fail to absorb energy unless it is made thick, so dropping on the side of the screen can result in a cracked screen. Another type of protective case is a soft "skin" that is generally made of rubber, polyoxyalkylene or another thermoplastic elastomer ("TPE") material. Like a rigid plastic housing, the skin is made for a particular device size and configuration, and therefore cannot be used in "next generation" devices. Other disadvantages are that they are roughly It is thin and therefore provides only minimal impact protection and most scratch protection. They also do not protect the device from significant drops on the sides of the screen, from corners or edges, and they do not provide torsional protection if the devices are bent or twisted upon impact.

Another type of protective case is a folder-style protective case to which the electronic device can be attached using clips, elastic bands, or other components. However, these types of protective cases do not provide side impact protection for the screen and provide substantially minimal impact protection.

A need for an improved protective case for sensitive equipment, devices or tools that is lightweight, flexible, and provides improved impact protection, especially for exposed screens or "in use" devices, and which are not It is specifically for a device size, but instead can accommodate a range of device sizes.

The present disclosure is directed to an embodiment of a protective case for a device. The protective case includes a flexible structural panel that includes a panel interior surface and a panel exterior surface. One of the inner and outer surfaces of the structural panels includes an extensible material, and one of the inner and outer surfaces of the structural panels includes an inextensible material. At least one flexible retention device is disposed on an interior surface of the panel. The at least one flexible retention device includes a layer of related material disposed between the layer of stretchable inner material and the layer of non-stretchable outer material.

Some embodiments include a cover member defining an inner cover member surface, an outer cover member surface, and opposing first and second cover member edges, the cover member The first edge is interconnected to the structural panel. In some embodiments, the cover member can include a selective protection element. Some embodiments can include fastening means to maintain the cover in a closed position and position the protective case as a frame.

The present disclosure is directed to a protective case that allows full access to the device when the device is in the protective case and in use, and protects the front, back, and side of the device from impact. In this way, the present protective case provides improved protection for devices having a screen interface, as found in many electronic and medical devices.

The protective case is lightweight, flexible, and provides improved impact protection, especially for exposed screens or "in use" devices. The protective box protects the corners and edges of the device and provides a torsional protection against twisting or bending of the device upon impact. Moreover, due to the flexible structure of the protective case, it is not specific to a certain device size, but instead can accommodate a range of device sizes. Due to its flexibility, the protective case is also comfortable to hold and carry. The protective case can also be comfortably used in a laptop clip or another body accessory due to its flexibility.

The protective case has the further advantage of being able to accommodate a range of device shapes. Thus, the protective cases can be designed and used in any type of sensitive device or item that can be protected, such as musical instruments, wine and alcoholic beverage bottles, crystals and the like.

The protective case and the method of manufacturing the same provide improved impact protection and lighter Weight, reduced volume, improved aesthetics, reduced manufacturing costs, improved fit, and less wear on included items. Moreover, in some cases, the protective boxes can be very hygienic as they can be designed to be cleaned and to withstand the high temperatures and corrosive chemicals used in commercial grade laundering.

1-11 show an embodiment of an exemplary protective case 10 in accordance with the present disclosure, when taken together. As shown, the protective case 10 includes a perimeter "P" and opposite front and rear sides 12, 14 each having a respective front and rear surface 12a, 14a. A retaining device 30 is disposed in each corner of the panel 20 (hereinafter "corner retaining device" 30). In the present embodiment, each of the retention devices 30 has a generally triangular shape and is positioned in a corner of the protective case 10. However, those skilled in the art will recognize that such retention devices need not have a triangular shape, and that any number, shape, location, and/or configuration of retention devices can be selected, and that the retention device can be positioned elsewhere. For example, another alternative configuration for the retention device 30 can include a single retention device shaped like a bezel (not shown) extending around the protective casing 10 by a width sufficient to retain a device in the protective casing. The perimeter extends inward. Another option may include providing more than one retention device 30 on the sides, such as on each side of the four sides, or at a plurality of points along the sides, or a combination of corners and sides. The retention device can be positioned to clamp the device while providing access to the ports, control mechanisms, and screen areas without obscuring the ports, control mechanisms, and screen areas.

In addition, a selective edge strip 40 can be used for function and aesthetics. It is disposed around the protective case 10.

The protective case 10 can also include a plurality of access ports to provide access to various functional devices on the device and/or to external devices such as battery chargers, audio ports, camera lenses, and the like. If desired, the access ports can be placed in any location to correspond to the location of such components as found on commercial electronic devices. In the present embodiment, the protective case 10 includes an audio port 50 that extends through one of the corner retaining devices 30; and a camera port 60 that extends through the panel 20. The camera port 60 is disposed on a planar, raised mat 65 formed in the protective case that is designed to be pressed against the back of the device when in use. As desired, the camera port 60 can include a film (not shown) integrated into the port to minimize debris or to eliminate debris from entering the port. As also desired, the mat 65 can include a recessed area (not shown) disposed about the camera port 65 for receiving the film which can be attached by, for example, bonding, etc. To the mat. If a film is used, it may be desirable to use a non-yellowing optical film that is resistant to laundering.

Another option, or in addition to the edge of the protective case, includes the bead strip being telescopic to expose and provide access to various functional devices. This is an important feature because the edge of the protective case (with or without a piping strip) includes the rate-related foam material, which maintains the edge of the device completely protected when in use and can be bent or folded for easy It can accommodate, for example, the charging line.

Panel 20 can be formed from a variety of materials. Suitable for making the panel The materials and methods are disclosed in U.S. Publication Nos. 2007/0261274, 2008/003614, 2009/0255625, the entireties of each of which are incorporated herein by reference. The foregoing application describes a method that can be used to mold the panels and retention devices and is used under conditions sufficient to minimize foam in the channels or to eliminate foam in the channels. The molds of the panels and retention devices can be designed to compress the layers together, allowing the layers to be bonded together by chemical bonding or thermal bonding, or both.

In some embodiments, panel 20 can comprise a structural material and additionally can include one or more layers of various materials having different aesthetic and functional characteristics, and which can be varied as needed or desired for a particular Application or design.

As used herein, "structural material" means any material having sufficient structural integrity to be formed into a predetermined shape, sufficient strength-to-weight ratio to provide structure to the protective casing, and capable of withstanding its intended The environment in which it is used.

The structural material can include various materials such as, but not limited to, polymeric materials, including foamed polymeric materials, synthetic materials, and the like. In an exemplary embodiment, the structural material can include rate dependent materials. Examples of rate related materials include, but are not limited to, d3O and Poron XRD. An exemplary structural material is available from Rogers Corporation under the product name Poron XRD®. In the exemplary embodiment, the Poron XRD® foam density can range from about 1 to about 40 pounds per cubic foot ("pcf"), more specifically from about 5 to about 30 pcf, more particularly From about 1 to about 25 pcf, and more specifically from about 15 to about 25 pcf.

The structural material may be combined or co-injected with other materials, including but not limited to synthetic and/or non-synthetic materials, including, but not limited to, paper, fabric, metal, metallized plastic, plastic film, metal foil And/or the like, and combinations thereof, and compositions, laminates, and/or at least one of the foregoing materials. Other suitable materials include, but are not limited to, fabric, leather, vinyl, composites, laminates thereof, and/or combinations comprising at least one of the foregoing materials. If a fabric is used, it can be synthetic or non-synthetic, woven, knitted, non-knitted, laminates thereof, and combinations comprising at least one of the foregoing materials. Any of the foregoing materials may be layered and/or may include a wrap on one or both surfaces to impart desired functional or aesthetic characteristics, such as water resistance to water and the like.

The use of extensible materials may be desirable when the panel or portions of the panel need to be stretched. Thus, in some embodiments, it may be desirable to combine or co-inject the structural material with the extensible material because the stretchable material improves the expansion and contraction of the protective case and imparts other desired characteristics, When non-lamellar features are desired, such as water resistance, breathability or water permeability, increased surface tension may be desirable. For example, when greater breathability is desired, the stretchable material can be a mesh fabric. As used herein, "extensible material" means any formable material that is capable of restoring its original shape or position after bending, stretching, compressing, or another deformation, and is capable of withstanding the being a method for forming the material and the protective case, and capable of withstanding the ring that it is intended to be used territory.

Other examples of suitable extensible materials include, but are not limited to, any extensible substrate, including TPE films and/or wraps, compositions thereof, laminates thereof, and combinations thereof. Polyester and polyether thermoplastic polyurethanes ("TPU") have been found to be suitable for use on their own, or in a layered form. A model material is a polyester thermoplastic polyurethane ("TPU") manufactured by Bayer and sold under the name PS5400. Suitable film thickness ranges from about 1 mil ("mil(s)") to about 15 mils, more specifically between about 2 mils to about 10 mils, and even more particularly about 3 mils to about 7 mils. However, when increased durability is desired, the film thickness can be increased to, for example, 15-60 mils, limited only by the characteristics and properties of the film after molding. When used in a layered form, it may be possible to reduce the film thickness by laminating the film to a substrate to enhance strength and wear characteristics. When laminated to an extensible substrate such as a circular knit or lycra fabric, a TPE film thickness of about 1 mil or less can be easily used in some applications.

Other examples of suitable extensible materials include, but are not limited to, synthetic and non-synthetic woven, knitted and non-knit fabrics, composites thereof, laminates thereof, and combinations thereof. Examples of suitable fabrics include those including fibers, such as elastane, which are also known under the product names of Spandex, Lycra, and Dorlastan, when incorporated in fabrics, by inelastic yarns (natural or One of the synthetics) is a fabric that is woven or woven with pure elastic fiber yarns made from other fibers to provide varying degrees of elasticity, depending on the percentage contained in the fabric. It depends on the type of fabric and the end use. For example, about 2% may be sufficient to allow the garment to retain its shape, and if desired, compression applications such as sportswear, undergarments, and sportswear may include up to about 40% or more of the elastic fibers.

Other examples of suitable extensible materials include the foregoing synthetic and non-synthetic woven, knitted and non-knit fabrics, composites thereof, laminates thereof, and combinations thereof, including those comprising TPE films and/or wraps, A composition, a laminate thereof, and combinations thereof.

When the panel or portions of the panel require more stiffness or tension, it may be desirable to incorporate the structural material with an inextensible material, or a material that has a relatively low stretch. Examples of non-stretchable materials include, but are not limited to, non-knitted materials, including non-knitted fabrics, leather, woven materials such as ballistic fabrics, and the like. Examples of such materials include, but are not limited to, fortified and unreinforced polyester, nylon, rayon, polyamide (such as decylamine and para-aramid), and the like, and combinations thereof. Examples may include Cordura, Kevlar, Twaron, Spectra, Zylon, woven fabrics thereof, and combinations thereof. Suitable ballistic material of a train by Luo Fulan Colorado Street City 8 of the sales company 418 RockyWoods 1680 Danny ballistic nylon braid, which has about 12 ounces per square yard (oz / yd ²⁾ weight of For polyurethane water repellency of about 1-1.25 oz/yd ² on one side and a durable water repellent ("DWR") surface treatment on the opposite side. Other suitable materials include 1050 ballistic nylon and Cordura, with and without the polyurethane wrap and/or DWR, available from Rockywoods, 275 South Patrick Road, Wyndham, Connecticut. And the Brookwood Roll Goods Group. It may be desirable that the polyurethane wrap on these fabrics will be heavier, such as 2.0 oz/yd ² or more, which may provide greater moisture resistance or durability. In addition, the laminate of TPE on these fabrics further enhances the water resistance.

In one embodiment, panel 20 can include a layer of structural material (hereinafter "structural layer") and a layer of extensible material ("extensible layer") disposed adjacent to the structural layer. In this embodiment, it may be desirable for the inner side 12a of the protective case to be formed of an extensible material that "clamps" the electronic device when it is placed in the protective case. .

In another embodiment, panel 20 can include a structural layer disposed between opposing stretchable layers. In this embodiment, it may be desirable for the inner side 12a and the outer side 14a of the protective case to be formed of an extensible material that "clamps" when it is placed in the protective case. The electronic device also clamps the surface on which the device can be docked or held during use.

The corner retaining devices 30 can include any of the materials used for the panel 20, as described above. When the electronic device is disposed in the protective case, the thumb-finger side of the retaining device to be formed by a material that "clamps" the electronic device may be desirable. Thus, the corner pieces may comprise a TPU or another film or material having certain "clamping" properties on the surface of the retaining device facing the device. TPU has been found to be suitable for clamping a variety of devices, but anthrone or any TPE or possibly some fabric or leather may also have such clamping properties. A demonstration material is made by Bayer Made of polyester TPU sold under the name PS5400. Another polyether TPU can be easily used, or any TPU or TPE will be a good choice. Suitable film thicknesses range from about 1 mil ("mil(s)") to about 15 mils, more specifically between about 2 mils to about 10 mils, and even more specifically about 3 The mil is about 7 mils.

The selective edge strip 40 can include any of the materials used for the panel 20, as described above. However, it may be desirable to combine the edge with the ballistic nylon or Cordura, with DWR, or with any other highly resistant and strain resistant or water resistant material to provide durability and water resistance.

When taken together, an exemplary panel 20 is shown in Figures 4-6. In this embodiment, the composite panel 20 is sized to be larger than the device to be protected so as to have edge protection extending beyond the perimeter of the device. As shown, the panel 20 includes a molded multilayer structure including a structural layer disposed between the inextensible inner layer 12 and the extensible outer layer 14.

In many embodiments, the panel can be molded into a region having a "lace trim", or a larger and smaller thickness, as described in the application discussed above, but it does not need to be so . However, areas containing very thin or "near zero" foam thicknesses can improve the expansion and contraction of the protective case and improve durability by minimizing peeling of the foam or preventing peeling of the foam. This near-zero region also allows for telescoping, which can be helpful because the portion is significant when stitched under tension so that it can accommodate a range of device sizes. These areas are also permitted to completely seal the area surrounded by the thickness of the near-zero foam material from moisture or dirt. The object, due to the closed cell structure, prevents the migration of moisture or dirt through it or minimizes the migration of moisture or dirt therethrough. These near-zero regions also allow for areas that will be easily heat sealed when the near-zero regions can be more easily joined without absorbing heat for bonding or obstructing any closed cell structure for bonding heat. It should be noted that it may be helpful to seal the film or other transparent material over the camera aperture or to seal the edge of the panel into a more water resistant structure. A more durable structure for laundering can be established around the near zero area of the periphery of the edge.

The panel 20 also includes a selective passage 22 spaced from the entire periphery 24 of the sheet and extending around the entire periphery 24 of the sheet. It may be advantageous to include such a passage if the retaining means and/or the selective trimming strip are attached by stitching. The passage 22 defines a damper portion 26 adjacent the periphery that can be enclosed in the edging strip material as previously discussed. The passage 22 has a width W ₁ and a thickness T ₁ , and the damper 26 has a thickness T ₂ and a width W ₂ . Those skilled in the art will recognize that any thickness or width can be selected as desired. For example, the width W ₁ of which may be selected to be large enough to accommodate a suturing tool, and is thin enough to suture, but is still sufficiently thick to cause the defect from the stapling operation to minimize or prevent defects from the suturing operation. E.g., about 0.030 "and a thickness T ₁ of about 0.125" thickness T ₂ of the damper material has been found to be suitable, such as those along the corner of the device is retained suture 30, the larger the damping material can be formed.

In this embodiment, the panel 20 and the corner retaining device 30 are sewn together along the sutures to form a support and protective edge, or shock absorber for the electronic device disposed in the protective case.

7-9 show an enlarged perspective view of an exemplary corner retaining device 30 that also includes a selective passage 22 spaced from the two sides 30a, b and extending around the two sides 30a, b. It may be advantageous to include such a channel if the retaining means and/or the selected piping strip will be attached to the panel by stitching. The passage 22 defines a damper portion 26 that abuts the edges 30a, b of the device 30. The passage 22 has a width W ₁ and a thickness T ₁ , and the damper 26 has a thickness T ₂ and a width W ₂ . Those skilled in the art will recognize that any thickness or width can be selected as desired. For example, the width W ₁ of which may be selected to be large enough to accommodate a suturing tool, and is thin enough to suture, but is still sufficiently thick to cause the defect from the stapling operation to minimize or prevent defects from the suturing operation. For example, the same thickness and width as the user of panel 20 have been found to be suitable.

The corner retaining devices 30 are of sufficient thickness to protect the device from impact, particularly when it includes a screen interface. The retention devices can have a thickness ranging from about 0.040" to about 0.500", more specifically from about 0.100" to about 0.350", and more specifically from about 0.150" to about 0.300".

The corner retaining device 30 also includes a notch 34 for stress relief during assembly and use, and a recessed region 38. In the present embodiment, the recessed area 38 has a concave or thumb-like shape that assists in the insertion of a device into the protective case 10. The presence of the recessed area also maximizes exposure of the device and/or screen surface when the device is positioned in the protective case, which would otherwise be hidden under the retaining device 30 for access. Functional keys are advantageous. Increasing or decreasing the thickness of the device can vary the exposure of the device and screen below the retention device 30. For example, the exposure apparatus of T ₃ may be increased by increasing the thickness of the apparatus in the region 31, when in use, which allows the recessed region is further separated by the apparatus.

The outline of the corner can be used for aesthetics as shown and provides access to the finger for removal and insertion of the device. Maximizing the thickness of the stitched edge toward the corner can help prevent the device from sliding too far to the corner or edge. As shown in these figures, it may be desirable to have a film surrounding the entire component. The recessed area in the corner retaining device allows for a greater thickness in the corner where it is needed for protection, but is inserted into the device and the entire area of the screen is accessed in and out of the corner retaining device to contact the screen. Sex. In some cases, the recessed areas in the corner retaining means are not required, but may be advantageous because they allow the corner retaining means to be sized, including the thickness to be maximized. As the size of the corner retaining device increases, particularly the thickness of the region closest to the stitching edges, the ability of the retaining devices to "lock" the device into the protective case increases and provides the ability to accommodate a wide range of device sizes. The thicker regions of the corner retaining device are compressible to accommodate different sized devices within a reasonable range.

Those skilled in the art will recognize that the channel, shock absorber, recessed area, and notch can be any size, shape, and/or configuration desired or desired to allow for easy attachment of the retention device 30 to The panel 20. In addition, the inclusion of additional grooves in the retention device may be desirable to provide additional flexibility during assembly and use.

The result of locking the corners of the molded foam material in the device, the molding The panel and the edge of the restrained foam suture flange are a protective case that protects the device from any type or orientation that is not subject to drop. The lateral movement of the device is limited as it is locked by the corner retaining means. The corner retaining means absorbs the impact from the drop on the side of the screen because the thickness separates the screen from the impact surface. The back side of the molded panel also absorbs energy. The recessed areas of the corner retaining means are raised above the screen in this area, and although they are thinner, they also provide added protection as they have the ability to absorb the energy in the telescoping of those areas during impact.

The structure of the protective case 10 involves attaching the retaining device 30 to the generally rectangular composite panel 20. The retention device 30 can be attached to the panel 20 using a variety of techniques including, but not limited to, stitching, gluing, joining, or a combination of the foregoing. In some embodiments, the retention devices 30 can be attached to the panel 20 under tension such that the panel 20 has a concave shape. When assembled, the retention devices 30 are positioned such that the "clamping" surface is positioned adjacent to the iPad. When stitched into this concave shape, the use of a relatively inextensible material such as a Cordura or ballistic nylon fabric, or another inextensible material for the composite panel, has the unique ability to create twist or twist protection for the frangible device Collaboration effect. In use, the device is inserted into the recessed, inextensible structure under relatively significant tension and is pressed against the corner retaining means. As a result, the device itself is imparted with increased torsional stability by the strength of the inextensible fabric structure, and is limited by the tension of the inextensible panel from being telescoped toward the open screen. Thus, the flexible protection box structure is hit Provides amazing twist or twist protection during the hit. The thickness of the foam in the corner retaining devices allows devices of different sizes to be tightly clamped.

The selective edge strip 40 can be placed around the circumference of the panel 20 such that it extends slightly beyond the passage of the panel 20 and the corner retaining device 30. The selective edge strip 40 can be attached using a variety of techniques including, but not limited to, stitching, gluing, joining, or a combination of the foregoing.

In this embodiment, when the electronic device is disposed in the protective case, the inner side 12a is formed by "clamping" the extensible material of the electronic device, and the outer side 14a of the protective case will be It can be desirable to form an inextensible material that provides improved wear resistance and/or high strength and/or sliding characteristics for the intended application. If the ballistic fabric is not co-injectable with the panel 20, it can be attached to the outer surface using a variety of attachment techniques including, but not limited to, stitching, gluing, joining, the like, and the like.

In this embodiment comprising the selective hemming strip 40, the hemming strip is attached by stitching. Accordingly, each of the structure of the panel 20 and the retention device 30 includes a suture channel disposed about the circumference of the panel and folded over the panel after the retention device has been attached to the panel Above the edge. The bead strip is then stitched to the panel through the suture through all of the layers.

10-11 show a perspective view and a cross-sectional view of the electronic device 70 (hereinafter "device 70") disposed in the protective case 10, such that the charging plugs on the device 70 are exposed to the protective case 10, when taken together. Right The cymbal 50 should be connected audibly, and the camera lens on the back of the device 70 is exposed to the corresponding audio port 50. As shown, the device 70 is disposed in the protective case 10 such that the corner retaining devices 30 are disposed over corresponding corners of the device 70. In combination with the inner surface of the protective case 10, the retaining devices 30 "clamp" or retain the device 70 within the protective case 10. In the present embodiment, the corner retaining means 30 is under tension so that the panel 20 is forced into a concave shape as shown in FIG. The spacer region "S" is formed between the rear surface of the device 70 and the front surface of the protective case 10 as a result of the concave shape of the panel 20. This space S is advantageous because it provides heat dissipation, a space for storage, and it minimizes the silencing or suppression of sound waves emitted from the horn or prevents sound waves emitted from the horn from being silenced or suppressed. The protective case as described can be used as such or placed in a sleeve for shipping and overall screen protection.

Figures 12-14 show another embodiment of an exemplary protective case 100 in accordance with the present disclosure when taken together. In the present embodiment, panel 20 includes a molded multilayer structure including a structural layer disposed between inextensible inner layer 12 and extensible outer layer 14. Therefore, in the present embodiment, when the device is inserted into the protective case, the protective case and the corner retaining device contact the surface of the device to have a "clamping" surface to help retain the device for protection. In the box.

In the present embodiment, the protective case can be made such that the corner retaining means 30 is under tension, as in the previous embodiment, to force the panel into a concave shape, as shown in FIG. The protective case can be used as such or placed in a sleeve for shipping and overall screen protection.

15-17 show another embodiment of an exemplary folder style protective case 200 in accordance with the present disclosure when taken together. This folder structure provides screen protection during shipping, but may not be needed for on-site use. The same materials and construction methods used in the previous embodiments can be used to make the present protective case.

As shown, the protective case 200 includes a retention panel 202 and a cover panel 204, each of which includes a selective edge strip 40 at the outer edge. In the present embodiment, the cover panel 204 can be attached to the panel 202 using various attachment methods. In the present embodiment, the panels 202, 204 are of the same size and shape and are attached to each other along an edge by stitching, or by interposing means such as hinges (not shown).

In the present embodiment, the structure of the panel 202 is identical to that of the protective case 100, including the peripheral "P" and the opposite front and rear sides 12, 14, each side having a corresponding front and rear surface 12a, 14a, and a retaining device 30 being It is disposed in each corner of the panel 20 (hereinafter "corner device 30"). As in other embodiments disclosed herein, each of the retention devices 30 has a generally triangular shape and is positioned in a corner of the protective case 10.

As shown, the protective case 200 includes a zip closure 25, but other types of closures can be used, such as devil felt, waterproof and/or air-proof zippers, plastic zippers (eg, Zip-Loc style), cushion flap closures. Piece, or any other closing method. The zip closure 25 can be attached to the outer edge of the panels by splicing the zipper teeth along the seam, and the panel at the end of the closure has a sufficient thickness to allow for the seam The operational defects are minimized or prevent defects from the stitching operation and are sufficient to provide protection in the zipper region. The folder protector utilizes a zippered edge, but the top can be attached using other fasteners including, but not limited to, a belt, a Velcro, a magnet clip, the like, and the like.

The protective case can be made by stitching, but in a protective case that is more resistant to water, the stitching can be replaced by any heat sealing, gluing or bonding.

If desired, the cover panel 204 can include a liner 23 that can be attached to the interior surface of the panel 204, such as by stitching. The cover panel 204 also includes a pocket 25 formed from the same material as the liner 23. If desired, the panel 204 can include additional pockets, or the receptacle can be included for documents, writing instruments, mobile phones, chargers, the like, and the like.

The protective case 200 can include a selective insert (not shown) disposed between the liner and the panel 204, which can comprise any rigid material or a composite structure involving a rigid material, or can be sufficiently rigid on its own, preferably A relatively light, hard, impact resistant plastic such as polycarbonate, acrylonitrile butadiene styrene ("ABS"), polyvinyl chloride ("PVC"), polypropylene ("PP"), Laminates, compositions thereof, and combinations thereof.
