CROSS REFERENCE TO RELATED APPLICATIONS 
       [0001]    The present application claims priority to U.S. Provisional Application No. 62/100,806 filed Jan. 7, 2015 titled “COMBINATION DUVET COVER AND COMFORTER SYSTEM” and U.S. Provisional Application No. 62/104,199 filed Jan. 16, 2015 titled “COMBINATION DUVET COVER AND COMFORTER SYSTEM,” which are hereby incorporated by reference in their entirety and for all purposes. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The field of the invention relates generally to the field of duvets/comforters and duvet covers. 
       BACKGROUND OF THE INVENTION 
       [0003]    Existing duvet covers use clips, snaps, ties or pins located generally in the corners to secure a comforter to a duvet cover. Unfortunately, these clips, snaps, ties and pins often became unattached from the comforter during sleep and bed-making, resulting in misalignment, bunching, tangling and twisting of the comforter inside the duvet cover. All of these factors create an uncomfortable sleep experience and sloppy appearance and often result in wasted time for users in fixing the arrangement between the comforter and duvet cover. 
         [0004]    One prior art solution is the “Du-Zipp” (sold online at https://www.etsy.com/shop/DuZipp) which is described as A zipper is sewn on the interior of the duvet and duvet cover on the seams. This method involves attaching a zipper to the interior side seam of a duvet cover but not within the layers of the duvet. As a result, all parts of the zipper (the zipper tape, the zipper teeth and the zipper slider) are all visible to the eye. A similar method is used on the duvet (comforter). This method attaches a zipper on top of a duvet (comforter) and as a result, all parts of the zipper (the zipper tape, the zipper teeth and the zipper slider) are visible to the naked eye, while in some a secondary strip of material is added over the exposed zipper in an attempt to hide the zipper, increasing cost and decreasing aesthetic appeal. 
         [0005]    Thus, needs exist for improved techniques to create secure connections between comforters and duvet covers. 
       SUMMARY 
       [0006]    Provided herein are embodiments of devices, systems and methods for improved securing of duvet cover and comforters. These improved systems, devices and methods include one or more of the following improvements. In some embodiments, certain fasteners will be attached along one or more interior sides of a duvet cover while complementary fasteners will also be attached along one or more corresponding sides of a comforter. In some embodiments, the comforter can be inserted into the duvet cover and, once inserted, the complementary fasteners on the sides of the comforter can be aligned with and attached or otherwise coupled to the complementary fasteners on the interior sides of the duvet cover. In some embodiments, a comforter and duvet cover can be joined by turning the duvet cover inside out, attaching the fasteners of the comforter to those of the duvet cover and then flipping the duvet cover right side out for normal use with the comforter located therein. Once connected, attached or otherwise coupled, the comforter can be securely attached to the duvet cover and will have a greatly reduced chance of becoming bunched up, tangled or twisted within the duvet cover. Fasteners can include many different types and combinations including hook and loop, hook and eye, zipper, snaps and others. 
         [0007]    Methods, systems and devices included herein can separate a zipper into two parts or halves, a male and female part respectively. One half of the zipper can be inserted between the top and bottom layers of a duvet cover so that a majority of zipper tape is hidden within the duvet cover layers, leaving only zipper teeth and a zipper slider and a very small portion of zipper tape visible to the eye from either an interior or exterior view. The other half of the zipper can be inserted between the top and bottom layers of the duvet (comforter) so that a majority of zipper tape can be hidden within the top and bottom layers, leaving only zipper teeth and zipper slider and a very small portion of zipper tape visible to the eye from an exterior view. Once the two halves of the zippers are aligned and engaged, for example, within an interior area of the duvet cover, the duvet cover and duvet (comforter) become connected. 
         [0008]    The placement of the zippers can be important for several reasons: 
         [0009]    Concealing zipper tape in between the top and bottom layers of both a duvet and duvet cover can prevent the zippers from becoming unattached from either the duvet or the duvet cover due to repeated use (zipping and unzipping), motion during a laundering process or movement during sleep. 
         [0010]    In addition, concealment of zipper tape can be important because it can prevent damage to both the duvet &amp; duvet cover from the zipper tape that may have sharp edges which could cause a tear in the fabric of either the duvet or duvet cover. 
         [0011]    Also, zipper tape material can fray &amp; break apart due to repeated use (zipping and unzipping), motion during the laundering process or movement during sleep, leading to inoperable zippers. Concealing and securing the zipper between the layers can protect from this and prevent fraying of fabric. 
         [0012]    When zipper tape is attached by insertion between layers, the attachment can be more secure because the layers as well as sewing or otherwise stitching hold the zipper in place, resulting in a more secure and functional operation. 
         [0013]    Positioning the zippers between layers can also create a clean, aesthetically-pleasing appearance for each piece. 
         [0014]    Not mentioned in the prior art but described herein is a uniform placement of all sliders. If multiple zippers are included, all halves of the zipper with sliders can be positioned on the duvet (comforter), with all non-slider halves on the duvet cover or the inverse positioning. 
         [0015]    While some prior art describes “exterior view with zippers attached,” users cannot see the duvet/duvet cover connection zippers as described herein once the duvet and duvet cover are attached, and the pieces are in their final position and the combination is seen from an exterior view. This can be important because having duvet/duvet cover connections on the exterior of the finished product can result in discomfort if the zipper comes in contact with the user and may even cause injury, skin irritation or other issues. Additionally, seeing duvet cover/duvet attachment zippers on the exterior is not aesthetically pleasing. 
         [0016]    While some prior art solutions describe “creating one solid unit,” the duvet covers described herein include interior edges which can connect directly to a duvet&#39;s exterior edges, leaving the body of the duvet free from attachment to the body of the duvet cover, allowing the two pieces to function together, while still allowing air to flow between the pieces for breathability. 
         [0017]    Herein, a zipper construction and placement is unique. Side length zippers, when inserted within the layers of the duvet cover and duvet and then connected, can result in the slider of a zipper (the part of the zipper you pull with your hand) terminating near the foot of the duvet/duvet cover combination. This can result in comfort and uniformity. In order to achieve this effect, one side length zipper can be fitted with a right hand separator, and the other side length zipper can be fitted with a left hand separator. 
         [0018]    In some embodiments described herein, duvet and duvet covers can be pre-manufactured in a factory and zippers can be added within the layers during the original manufacturing process of both the duvet and duvet covers. As such, manufacturing using CAD (Computer Aided Design), patterns can include making and manufacturing technology to create a precision fit. This is in contrast to prior art solutions which may be added in a secondary process. 
         [0019]    Other systems, devices, methods, features and advantages of the subject matter described herein will be or will become apparent to one with skill in the art upon examination of the following figures and detailed description. It is intended that all such additional devices, methods, features and advantages be included within this description, be within the scope of the subject matter described herein, and be protected by the accompanying claims. In no way should the features of the example embodiments be construed as limiting the appended claims, absent express recitation of those features in the claims.

         [0088]    In various embodiments described herein and otherwise contemplated, fasteners can include zippers, hook and loop (Velcro), hook and eye, snaps, buttons, ties or various others as will be appreciated by one of skill in the art. Additionally, combinations thereof are contemplated, such as fasteners of one form (e.g. zipper) with attachment at fabric locations by backing using fasteners of another form (e.g. a series of buttons along a zipper backing). Adhesives can include various chemicals and compounds and can be in the form of strips, liquids, glues, aerosols, gel, putty, heat cured adhesives, iron-on adhesives or others as appropriate. Adhesives may be applied to fasteners at appropriate locations such as backing or strips attached to fasteners and may be manufactured with the fasteners or applied separately by end-users in various embodiments. Fasteners can be applied in some embodiments as follows: one half of an adhesive zipper can be applied to an interior of the duvet cover in an appropriate location as shown in the various figures described herein. In particular a first half of the adhesive fastener can be applied to a location of the interior of a duvet cover, such as near the side seam area. The second half of the adhesive fastener, operable to mate with the first half, can be applied to a location of a comforter to be joined with the duvet cover, such as near an edge of a comforter. When fastened, joined, coupled, connected, zipped, hooked, or otherwise attached together, the comforter and duvet cover will be joined such that they cannot freely move with respect to each other at the joined location, thereby hindering or preventing shifting, bunching and twisting of the comforter within the duvet cover during use. 
         [0089]    An embodiment will now be described in which a fastener in the form of a zipper is included in a fabrication process to create a permanent connection. It should be understood from the disclosure herein that other fasteners can be used and variations on manufacturing are also possible. 
         [0090]    Methods, systems and devices included herein can separate a zipper into two parts or halves, a male and female part respectively. One half of the zipper can be inserted between the top and bottom layers of a duvet cover so that a majority of zipper tape is hidden within the duvet cover layers, leaving only zipper teeth and a zipper slider and a very small portion of zipper tape visible to the eye from either an interior or exterior view. The other half of the zipper can be inserted between the top and bottom layers of the duvet (comforter) so that a majority of zipper tape can be hidden within the top and bottom layers, leaving only zipper teeth and zipper slider and a very small portion of zipper tape visible to the eye from an exterior view. Once the two halves of the zippers are aligned and engaged, for example, within an interior area of the duvet cover, the duvet cover and duvet (comforter) become connected. 
         [0091]    The placement of the zippers can be important for several reasons: 
         [0092]    Concealing zipper tape in between the top and bottom layers of both a duvet and duvet cover can prevent the zippers from becoming unattached from either the duvet or the duvet cover due to repeated use (zipping and unzipping), motion during a laundering process or movement during sleep. 
         [0093]    In addition, concealment of zipper tape can be important because it can prevent damage to both the duvet &amp; duvet cover from the zipper tape that may have sharp edges which could cause a tear in the fabric of either the duvet or duvet cover. 
         [0094]    Also, zipper tape material can fray &amp; break apart due to repeated use (zipping and unzipping), motion during the laundering process or movement during sleep, leading to inoperable zippers. Concealing and securing the zipper between the layers can protect from this and prevent fraying of fabric. 
         [0095]    When zipper tape is attached by insertion between layers, the attachment can be more secure because the layers as well as sewing or otherwise stitching hold the zipper in place, resulting in a more secure and functional operation. 
         [0096]    Positioning the zippers between layers can also create a clean, aesthetically-pleasing appearance for each piece. 
         [0097]    A uniform placement of all sliders is contemplated in various embodiments. If multiple zippers are included, all halves of the zipper with sliders can be positioned on the duvet (comforter), with all non-slider halves on the duvet cover or the inverse positioning. 
         [0098]    Due to the positioning of zippers described herein, users cannot see the duvet/duvet cover connection zippers as described herein once the duvet and duvet cover are attached, and the pieces are in their final position and the combination is seen from an exterior view. This can be important because having duvet/duvet cover connections on the exterior of the finished product can result in discomfort if the zipper comes in contact with the user and may even cause injury, skin irritation or other issues. Additionally, seeing duvet cover/duvet attachment zippers on the exterior is not aesthetically pleasing. 
         [0099]    Additionally, the duvet covers described herein include interior edges which can connect directly to a duvet&#39;s exterior edges, leaving the body of the duvet free from attachment to the body of the duvet cover, allowing the two pieces to function together, while still allowing air to flow between the pieces for breathability. Separation of zippers allows for the comforter and duvet cover to be uncoupled and cleaned separately, as desired by a user. 
         [0100]    In some embodiments a zipper construction and placement can include side length zippers which, when inserted within the layers of the duvet cover and duvet and then connected, can result in the slider of a zipper (the part of the zipper to be pulled by a user&#39;s hand when coupling or uncoupling zipper halves) terminating near the foot of the duvet/duvet cover combination. This can result in for comfort and uniformity. In order to achieve this effect, one side length zipper can be fitted with a right hand separator, and the other side length zipper can be fitted with a left hand separator. 
         [0101]    In some embodiments described herein, duvet and duvet covers can be pre-manufactured in a factory and zippers can be added within the layers during the original manufacturing process of both the duvet and duvet covers. As such, manufacturing using CAD (Computer Aided Design), patterns can include making and manufacturing technology to create a precision fit. 
         [0102]    As used herein and in the appended claims, the singular forms “a”, “an”, and “the” include plural referents unless the context clearly dictates otherwise. 
         [0103]    The publications discussed herein are provided solely for their disclosure prior to the filing date of the present application. Nothing herein is to be construed as an admission that the present disclosure is not entitled to antedate such publication by virtue of prior disclosure. Further, the dates of publication provided may be different from the actual publication dates which may need to be independently confirmed. 
         [0104]    It should be noted that all features, elements, components, functions, and steps described with respect to any embodiment provided herein are intended to be freely combinable and substitutable with those from any other embodiment. If a certain feature, element, component, function, or step is described with respect to only one embodiment, then it should be understood that that feature, element, component, function, or step can be used with every other embodiment described herein unless explicitly stated otherwise. This paragraph therefore serves as antecedent basis and written support for the introduction of claims, at any time, that combine features, elements, components, functions, and steps from different embodiments, or that substitute features, elements, components, functions, and steps from one embodiment with those of another, even if the following description does not explicitly state, in a particular instance, that such combinations or substitutions are possible. It is explicitly acknowledged that express recitation of every possible combination and substitution is overly burdensome, especially given that the permissibility of each and every such combination and substitution will be readily recognized by those of ordinary skill in the art. 
         [0105]    In many instances entities are described herein as being coupled to other entities. It should be understood that the terms “coupled” and “connected” (or any of their forms) are used interchangeably herein and, in both cases, are generic to the direct coupling of two entities (without any non-negligible (e.g., parasitic) intervening entities) and the indirect coupling of two entities (with one or more non-negligible intervening entities). Where entities are shown as being directly coupled together, or described as coupled together without description of any intervening entity, it should be understood that those entities can be indirectly coupled together as well unless the context clearly dictates otherwise. 
         [0106]    While the embodiments are susceptible to various modifications and alternative forms, specific examples thereof have been shown in the drawings and are herein described in detail. It should be understood, however, that these embodiments are not to be limited to the particular form disclosed, but to the contrary, these embodiments are to cover all modifications, equivalents, and alternatives falling within the spirit of the disclosure. Furthermore, any features, functions, steps, or elements of the embodiments may be recited in or added to the claims, as well as negative limitations that define the inventive scope of the claims by features, functions, steps, or elements that are not within that scope.
