Abstract:
A reusable package and storage album ( 1 ) displays and stores a multi-component product, combining the appearance of a blister pak with the security of a vacuformed clamshell package. Two sections ( 17  &amp;  19 ) joined by hinges ( 43  &amp;  45 ) to a spine ( 21 ), formed principally of plastic ( 11 ) and paperboard ( 9 ) materials, fold into a book or album-like structure to house the product components. Ample advertising space ( 9 ) is available on the exterior ( 3, 2, 21 ) and interior ( 23 ) surfaces for a layer of printed matter ( 13 ). The album type storage ( 17, 37, 19, 23 ) is helpful, discourages disposal of the packaging, which aids the environment, and allows manufacturer advertising and other printed information to persist beyond the sale. Hinges ( 43, 45 ) comprise an inverted rectangular U-shape in section in geometry. Windows ( 5, 7, 12 ) may be included to allow a view of the components. A window ( 5 ) formed in one album section ( 17 ) may be recessed to also prevent a component in the other album section ( 19 ) from flopping about when handling the package.

REFERENCE TO PRIOR APPLICATIONS  
       [0001]     Reference is made to U.S. application Ser. No. 10/371,361, filed Feb. 24, 2003, entitled “Reusable Environmentally Friendly Package and Storage Album”, assigned to the assignee of the present application, of which the present application is a continuation-in-part. Applicant claims the benefit of 35 U.S.C. 120 with respect to the foregoing application. 
     
    
     FIELD OF THE INVENTION  
       [0002]     This invention relates to point of sale display and reusable storage albums for consumer product, and, more particularly, to a reusable package that permits both in-store advertising induce product purchase and convenient reusable post-sale storage for the product.  
       BACKGROUND  
       [0003]     At retail, small low-cost consumer products, such as toys, novelty items, batteries, cameras, video games and the like are displayed in the retail store on shelves or hang from racks from which the consumer may remove one for inspection and/or purchase. Frequently those products are packaged in blister paks or in vacuformed clamshell packages, widely known to the purchasing public. In the familiar blister pack the item is encased in a transparent plastic “bubble”, a thin piece of transparent plastic that forms a shroud or dome like structure about most of the product, that is heat sealed or glued to a card of paper board or other fiber based printable material. The paper board card contains the printed or lithographed text and/or graphic material, such as the brand, model information, regulatory information and discretionary advertising, some of which may be viewed through the plastic bubble. An end of the cardboard and/or plastic material contains or is shaped as a hanger or contains an attached hanger so that the package may be hung from an extending rod of the display rack. The blister pak package is convenient for the retailer, since, for one, the bubble pak discourages pilfering by an errant customer or employee and generally allows the customer to visually inspect the item before making the purchase. In some such packages for some products a sheet of instructions is included.  
         [0004]     To extract the article from the package following purchase, the purchaser needs to tear the plastic bubble away from the cardboard. Now destroyed, the bubble pak is discarded as waste. If an instruction sheet is included the sheet is typically discarded after first use or misplaced. And if the purchased article contains multiple items, such as an instruction booklet and camera, a book and crayons or multiple small toys, e.g. a multi-component article, the destroyed package can&#39;t be used later to store the items. After initial use the purchaser is left to make other arrangements for storage.  
         [0005]     Like the bubble pak, the vacuformed clamshell package is also widely known to consumers and, typically, permits the purchaser to visually inspect the packaged product. The vacuformed plastic case of the clamshell package is sealed along seams. As commonly known, it is not possible to easily remove the product (or components of a product) from that package with one&#39;s bare hands. Opening the package is somewhat of a struggle and requires use of a sharp heavy duty scissor or knife to cut apart the plastic and extract the product. The destroyed clamshell package is no longer useful and, like the bubble pak, is also discarded in the waste. Similarly, if the purchased item is a multi-component article, the destroyed package is unavailable to later store the items together and the purchaser needs make other arrangements for post-use storage.  
         [0006]     The difficulty experienced by the customer with the clamshell packages produces some complaints, particularly from those customers who may have been injured by the sharp edges exposed by cutting through the somewhat thick plastic of the vacuformed clamshell packages. For that reason alone one finds need for a package that can be opened more easily than those packages, particularly for those products intended for purchase by young mothers for their young children, even though that may somewhat compromise the anti-pilfering benefit of the prior packaging. As an advantage the present invention provides such a package, yet protects the manufacturer&#39;s interest in including advertising to induce purchases and, in some embodiments allows the customer to visually check the presence of a part of the contents.  
         [0007]     A greater difficulty experienced by the customer is the lack of storage available for the multiple components of a product, once the package is destroyed to permit product removal. As previously noted the purchaser must make other arrangements for storage of the multiple components so that they do not become separated and lost. To store the parts of the product together the purchaser must exert additional effort to find or purchase a separate container to hold the components, a definite inconvenience and increase in expense for ones customer. Failing in that effort the product components are more likely to be separated and misplaced, which would halt use of the product. Even if one of the components is a simple instruction sheet, the instructions should be retained and stored. The loss of the instruction sheet can be problematic should one need to access the instructions a year or so after the product was first used.  
         [0008]     Not only does the lack of storage capability produce an inconvenience for the purchaser, but the manufacturer of the product may find that his product fades prematurely because the product falls into non-use. The benefit of word of mouth advertising of a pleased customer is lost. As an advantage, the present invention adds value to the package for both the manufacturer and the customer, enabling the point of display package not only to achieve all of the advertising benefit of the foregoing prior packages (and more), but provides for storage of the product following the purchase. The present invention may be used and reused to store the product components.  
         [0009]     Frequently a product manufacturer, such as a toy company, goes to great length in its package advertising, not only to induce the product purchase, but also to induce purchases of other products as well following the originally purchase, referred to as cross-sell advertising. That cross-sell advertising is lost once the package is discarded. As an advantage, the present invention retains that cross-sell advertising and results in that advertising being available to the consumer each time the product is removed from storage for use. With the present invention even the basic instructions may be preserved so that they can never be misplaced, lost or discarded.  
         [0010]     The advent and rapid growth of the warehouse type retail stores perhaps accelerated the trend to rack type display of retail product in essentially pilfer proof packaging, such as the bubble pack and vacuum formed clamshell packages. With large quantities of merchandise and limited numbers of sales clerks available to assist the retail customer or watch over unpackaged small size merchandise it became unacceptable to permit unsupervised store patrons to open a package to inspect a product and/or retrieve one or more of the components in the package and possibly misplace them or, exercising self-help, remove the component as replacement for an earlier failed purchase, avoiding the long lines encountered in returning a failed product. As that pilfer proof packaging becomes more widespread, the quantity of discarded plastic packaging grows.  
         [0011]     Discarding of plastic packaging materials appears of concern to many. Those materials are difficult to decompose. As the quantity of such discarded materials mounts obvious difficulties are posed to the environment. By retaining the packaging materials for as long as possible the problem of disposal could be avoided or deferred long into the future. As a further advantage, the present invention induces the purchaser to save, use and re-use the plastic packaging; and, in that sense, the invention is considered environmentally friendly.  
         [0012]     One feature of the described prior package structures that is of advantage to both manufacturer and consumer is that the components of a multi-component product are held in place in the package and cannot rattle when the package is shaken. Hence, the components are not subjected to extra shock during transport and the consumer will not hear a rattling sound on handling the package as would cause that consumer to think that something is wrong with the product. As a further advantage, the present invention also incorporates that anti-rattling feature.  
         [0013]     Accordingly, a principal object of the present invention is to provide a package or container for retail product that has the appearance of a blister pak and the security of a clamshell type package.  
         [0014]     A further object of the invention is to enhance the retail customer&#39;s awareness of a multi-component product prior to purchase in a secure package.  
         [0015]     A still further object of the invention to reduce the volume of discarded plastic packages and thereby make plastic packages for product more environmentally friendly.  
         [0016]     Another object of the invention is to induce retail consumers to refrain from discarding plastic packaging for a product following the product purchase.  
         [0017]     Still another object of the invention is to enhance the value of point of sale packages for product by ensuring the consumer&#39;s retention and post-sale use of the packages.  
         [0018]     An ancillary object of the invention is to enable the purchaser of product to remove product from the plastic packaging without destroying the package.  
         [0019]     And a further ancillary object of the invention is to induce the customer to retain the advertising materials associated with the product following sale and prevent consumer misplacement of basic instructions for operation of the product.  
       SUMMARY OF THE INVENTION  
       [0020]     In accordance with the foregoing objects and advantages, a reusable package and storage album displays and stores a multi-component product, combining the appearance of a blister pak with the security of a vacuformed clamshell package. Two housing sections pivotally joined by hinges to a spine fold into a book-like or album-like structure to house the product components. Ample advertising space is available on the surfaces of the housing for a layer of printable material providing printed text and graphics on front and back surfaces. The album-type storage is helpful, discourages disposal of the packaging, which aids the environment while providing convenient storage and re-use, and allows manufacturer advertising and other printed information to persist beyond the initial retail sale of the product.  
         [0021]     Further in accordance with one embodiment of the invention the two housing sections, spine and hinges are formed in a unitary one-piece structure of transparent plastic material. A paperboard sheet is attached, directly or indirectly, to a surface of the housing sections and spine. In one embodiment the paperboard sheet contains printed material on each of the front and back surfaces and a layer of transparent paperboard-to-plastic bonding material on the front surface that faces the housing sections, permitting one side of the paperboard sheet to be viewed through the transparent plastic material and the opposite side t be viewed directly. Sealing means may join the two sections together to prevent tampering with the product prior to purchase.  
         [0022]     In accordance with another embodiment, the paperboard sheet may be very thin, even reduced in thickness as to constitute paper. In accordance with still another embodiment of the invention the paperboard sheet is very thin and contains printed material on each of the front and back surfaces. That printed sheet is sandwiched between the back surface of the unitary assembly of transparent plastic housing sections and spine and an additional flat transparent plastic sheet defining a plastic laminate-like arrangement that permanently encases the printed sheet. Both sides of the paperboard sheet are viewed and read through transparent plastic material.  
         [0023]     In accordance with a specific aspect of the invention the sealing means may be any of tape, a glue, a heat sealable glue, an ultraviolet light sealable glue and an ultrasonic weld.  
         [0024]     In accordance with another specific aspect to the invention, the plastic material may be any of polyvinyl chloride, polypropylene, polyethylene and polystyrene.  
         [0025]     In accordance with still another embodiment, the package may include one or more windows to allow a view of the components without opening the package. In a still more specific aspect, a window formed in one section may be recessed to also prevent a component in the other section from flopping about when handling the package.  
         [0026]     The foregoing and additional objects and advantages of the invention together with the structure characteristic thereof, which was only briefly summarized in the foregoing passages, becomes more apparent to those skilled in the art upon reading the detailed description of a preferred embodiment, which follows in this specification, taken together with the illustration thereof presented in the accompanying drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0048]     Reference is made to  FIGS. 1 and 2 , illustrating one embodiment of the album-like package or album  1  in top plan view and side view, respectively. Album  1  is generally rectangular in shape and resembles an ordinary text book in geometry and size so as to conveniently fit on a bookshelf or other shelf for convenient storage. The exposed surface of the cover or top panel  3  is opaque to light. That surface is covered by an opaque treated printable material, suitably, treated paperboard material  9 , that is attached to and overlies transparent plastic material  11  (as represented by the cutaway in the lower right of the figure) that defines the structure of the package, both of which are later herein more fully described. The top panel also contains transparent (e.g. light transmissive) openings or windows  5  and  7 . Those windows are formed by cut-out openings or windows in treated paperboard material  9 , exposing a portion of the underlying transparent plastic material  11  that serves as the window pane and admitting exterior light in the visual range into the interior of the package. The windows permit the contents of the package to be partially observed, such as the cover of a book  4 , titled “The Good Book”, generally represented in the figure, but which does not form part of the package.  
         [0049]     The panel surface includes printers ink  13 . The printers ink is arranged to define printed material, such as text and/or graphics symbols and background color, to provide advertising, brand names, contents description and other information and a pleasant appearance to the retail consumer. An example of such text is represented in the figure by the term “learning store”, as it is not practical to display all of such text and graphics. As later discussed in connection with  FIG. 6 , the reverse side of the treated paperboard material  9  also contains printers ink that conveys information, color and/or graphics.  
         [0050]     A hanger or hook  15 , preferably formed integrally in a package wall, is included to permit the package to be hung on a conventional retail point-of-sale display rack. A tear line, not illustrated, in the plastic adjacent the base of the hook should allow removal of the hook following purchase of the article. Alternatively, in other embodiments the hook may be formed as a structure separate from the package and is attached to the package by tape or other adhesive that may conveniently be removed following the purchase of the product.  
         [0051]     As illustrated in the lower side view of  FIG. 2 , package  1 , shown closed, is of an album type structure containing sections  17  and  19  joined together by a spine  21  to which the two sections are hinged. As also illustrated in  FIG. 2  and in the front edge view of the package in  FIG. 3 , like a book, the outer surfaces of top panel  3  and bottom panel  2  are flat. The end of the package opposite the end shown in  FIG. 2 , not illustrated, is a mirror image of the view of  FIG. 2 .  
         [0052]     Spine  21  is joined to the respective sections by hinges, not illustrated in the figure and later herein described, that extend the length of the package height as presented in the side view of the closed package (opposite to the side of  FIG. 3 ) illustrated in  FIG. 4 . The outer surface of spine  21 , actually, as becomes apparent later in this description, a psuedo-spine, is also a treated paper board material that is scored along hinge lines and attached to the underlying spine of the plastic material, the latter of which is not visible in this view. As with the outer surface illustrated in  FIG. 1 , the treated paper board is opaque and contains printers ink  13  that defines textual information and/or graphics, as represented, as example, by the term “The Good Book.” 
         [0053]     The lower panel or back side of the package  2 , opposite to that of  FIG. 1 , is illustrated in  FIG. 5 . The exposed surface of that side is also formed of the treated opaque printable paper board material used on the front cover and spine. In practice, the treated paper board surfaces are formed of a single sheet of treated paper board as described later herein in connection with  FIG. 8 . That treated paperboard is attached to the underlying plastic material of the wall of section  19  and also contains printers ink  13  on the outer surface. The printers ink on this panel also provides text and graphic symbols intended to provide information to a potential purchaser of the product. As later described, the opposite side surface of the foregoing paperboard surface also contains printers ink defining printed matter. A cut-out region in the treated paper board serves as an additional light transmissive window  12  to the underlying transparent plastic material of the package and through that plastic material into the interior of the package.  
         [0054]     Package  1  is illustrated open and in perspective in  FIG. 6  to which reference is made. In this view the package is open with the two housing sections  17  and  19  positioned on respective sides of spine  21 . Hinges  43  and  45  respectively connect opposite elongate edges of spine  21  to an elongate edge of top panel  3  and bottom panel  2 , respectively, joining the sections and permitting section  17  to pivot into mating engagement with section  19  and vice-versa to close the package as earlier illustrated in  FIGS. 1-5 .  
         [0055]     The disclosed embodiment is designed to hold a multi-part child&#39;s toy that contains a book  4  (earlier partially viewed through window  5  in  FIG. 1 ) and a plug-in ROM cartridge  10 , an add-on accessory to a game or educational computer unit, not illustrated, which are shown in exploded view. The book fits loosely inside a recessed tray, receptacle or compartment  23  inside section  19 . That compartment is defined by a bottom wall to the section and by a raised shoulder  25  that extends in a closed rectangular loop about the upper surface of package section  19 . The book compartment is designed to be slightly greater in length and width dimensions than the corresponding dimensions of book  4  and is deep enough to receive the book so that the book easily fits inside the formed compartment and may be easily withdrawn when needed.  
         [0056]     Another formed narrow shoulder  27 , shorter in height than shoulder  25 , extends about the outer periphery of shoulder  25  adjacent a formed flange  29  to the section. That shoulder engages a corresponding shoulder  34  in section  17 , later herein described when the package is closed. Flange  29 , which defines the outer edge of section  19 , extends in a web about three sides of the section, but not along the spine  21 . A like flange  31  is included in the other package section  17 .  
         [0057]     Section  19  also contains an additional light transmissive transparent window  12  through which a portion of the book may be viewed from the package exterior when the package is closed. The location of that window is determined by the designer who is guided by the particular information contained on the back cover of book  4  that is desirably displayed. As example, that information may be information that is required by regulation, such as the country in which the book was printed, or notices for the consumer, such as information on trademark ownership and/or copyright information on the book.  
         [0058]     Section  17 , on the left of the figure, also includes a flange  31 , a first outer shoulder  33  upstanding from the base that extends in a closed rectangular loop about the section defining a four-sided compartment on top panel  3 , and a second inner shoulder  35  upstanding from the base, adjacent to the former shoulder, that also extends in a closed rectangular loop defining an internal region in the section. In this section the outer shoulder  33  is greater in height than inner shoulder  35 . Those shoulders are sized to mate with the corresponding shoulders of the other section to enable the package to close to the book-like shape (as was illustrated in  FIGS. 2 and 3 ) and the side walls of the two outer shoulders  33  and  25  of the respective sections frictionally engage when the package is closed. That mating engagement tightly closes the package.  
         [0059]     As better illustrated in this figure the pane of window  5  is recessed from the plane of the outer cover surface  3  and protrudes into the rectangular frame formed by shoulder  33 . In addition to passing light through to the interior (and vice-versa), the flat surface of the plastic window also functions to prevent the book from tilting from the bottom wall of compartment  23  when the closed filled package is held upright (e.g. flopping), preventing the book from rattling in the closed package during transport or when the package is handled by a prospective purchaser. The distance by which the flat transparent plastic surface of the window protrudes from the plane of top cover  3 , the depth, as defined by the window frame  8 , is determined by the thickness of the installed book  4 . The flat surface of window  5  should be at least contiguous with the cover of the installed book or may even press slightly against the flat surface of the book when the book is placed in receptacle  23  and the package is closed. That provides for a wider tolerance in manufacture and/or for slight change in book thickness.  
         [0060]     When the surface of window  5  presses against the book, the inherent elasticity of the plastic material forming the window produces a slight pressure (e.g. compressive force) to more firmly hold the book in place in the compartment, while the reactive force produced thereby between sections  17  and  19  does not exceed the frictional strength of the frictional engagement between those two mating sections when the package is closed. As one appreciates, other embodiments of the package may be designed to hold articles other than a book and the size and/or shape of the recessed window may be varied accordingly, while permitting a portion of the other article to be visually inspected.  
         [0061]     A pocket or receptacle  37  is located on the inside surface of section  17  which is designed to hold another component of the multi-component article. In this embodiment that receptacle is for holding the semiconductor ROM plug-in cartridge  10 , which does not form part of the package. Pocket  37  is formed by a raised shoulder  39  on the inside surface of the section that extends in a closed loop. The inside surface of the shoulder defines a region that is of the same essential geometry of the of cartridge  10 , but is slightly smaller in size so that cartridge  10  may be held in place. The cartridge must be pressed into the pocket and is frictionally held in place by the side walls of shoulder  39 . The hollow walls of that shoulder, formed of the same thin plastic material previously described, exhibits sufficient flexibility to capture and hold the cartridge.  
         [0062]     Two depressions  41  at diametrically opposite locations in that shoulder define finger holes permitting the user to grip cartridge  10  from the side with two fingers and pull the cartridge from the receptacle. Pocket  37  is located over window  7  with the transparent plastic material of that window serving also as the bottom wall of the receptacle. Thus, a purchaser is able to view the content of the receptacle from the exterior of the package.  
         [0063]     Although the foregoing embodiment is intended for use with a two component product and contains only a single pocket in section  17 , the invention is not limited to that number of pockets. As those skilled in the art appreciate, in other embodiments of the invention intended to package a multi-component product that contains a greater number of components, additional pockets of the foregoing type (and additional windows associated with those additional pockets, may be formed in the section to hold (and display) those additional components.  
         [0064]     Reference is made to  FIG. 7  which is an inverted section view taken along the lines  7 - 7  in  FIG. 6 . The section view assists in a review of the manner of manufacturing the invention. The plastic portion  11  of the package is first considered. The preferred plastic material used in the preferred embodiment is polyvinylchloride (“PVC”). However, it should be understood that other less preferred plastic materials may be substituted. Thus the term plastic or plastic material should be construed to include not only PVC, but also polypropylene, polyethylene (“PET”), polystyrene and any other equivalent material that gives the housing sections a relatively rigid form and is used for packaging, whether existing or that may be developed hereafter. Briefly, transparent PVC is supplied by the manufacturer as a flat rolled sheet of PVC plastic of the desired thickness and size. Using conventional thermoforming processes the flat sheets are transformed using an appropriate mold and heat to permanently reshape the plastic material into the desired three-dimensional shape illustrated, including the recessed window, right and left sections, the spine and hinges previously described. The process of thermoforming plastic is known and has been used to form the vacuformed plastic packages, also sometimes referred to as thermoformed packages.  
         [0065]     That process simultaneously produces the deep recesses or depressions on one side of the sheet that produce the hollow shoulders  25  and  27 ,  33  and  34 , the recessed window  5 , the hollow should  39  of the pocket, earlier described, that protrude from the opposite side of the sheet. That thermo-forming process also produces the hinges  43  and  45 . The foregoing three-dimensional structure is seen as an integral structure formed of one piece of plastic material. Once formed the structure is removed from the mold.  
         [0066]     The manufacture of the treated paper board material  9  is next considered. Reference is made to the partial section view of  FIG. 8  taken along the lines  8 - 8  in  FIG. 7 . This section view shows the layers of the treated paper board material  9  as attached to the formed plastic structure  11 . Printable material  9 A of the appropriate size and thickness is supplied to the printer who applies printer&#39;s ink to the front and reverse side of the paper board sheet, producing ink layers  9 B and  9 C. That ink prints the text, background color and graphics material supplied by the packaging artist for the front and reverse sides of the paper board. By printable material it should be understood that such term encompasses ordinary printing, lithography and any other printing process that applies ink (or dye), as example, to paper or paper board materials and the like. The printers ink is applied to define textual and graphics information for the consumer. Brand names, product features and graphic characters, as example, provided on the side of the paper board that is located outside of the container assist to induce the customer to inspect and purchase the article. On the reverse side of the paperboard the printer&#39;s ink may define additional information on product start up and use of the type that often is presented on a separate sheet of paper, product support information, and further use of brand names and graphic characters. On some portions of the paper board, the printer&#39;s ink may be a simple background color.  
         [0067]     Once printing is completed, the sheets of the printed board are coated on the inside surface with a thin transparent layer of a heat sealable compound  9 D or other adhesive that covers the printer&#39;s ink on that side. The layer of sealing compound is transparent so as to permit incident light to pass through and allow the printer&#39;s ink on layer  9 C to receive incident light and show through. One such compound (also referred to as an ink) is the GV Series Vinyl Screen Ink, a vinyl lacquer, sold by the Azdar Company of Chicago, Ill. That UV material is heat sensitive and can bond the treated paper board with PVC when heat is applied with pressure.  
         [0068]     Then the treated paper board material is die cut to form the window openings  5 ,  7  and  12 . That material is also scored along the lines of the two hinges that weakens the paper board material at those locations overlying the living hinges  43  and  45  formed in the plastic sheet and, when the treated paper board is bonded to the plastic, as next described, allows the paper board to fold more easily.  
         [0069]     The next step is to attach the treated paper board  9  to the flat side of the thermoformed plastic material  11  as illustrated in  FIG. 7 . The printed and coated paper board is then properly aligned on the flat side of the thermoformed plastic with the heat sealable bonding coating  9 C contacting the plastic  11  and the score lines  44  and  46  aligned with the respective hinges  43  and  45 . The assembly is then placed in an oven where the heat sealing coating is activated and heat seals the treated paper board to the thermoformed plastic. As bonded to the thermoformed plastic  11 , the treated paper board covers any opening or deep depression in that surface. The score lines  44  and  46  overlie and are aligned with the formed plastic hinges  43  and  45 , but those formed plastic hinges remain detached from treated paper board  9 .  
         [0070]     The package is ready to be stuffed with the multi-component product. In the illustrated embodiment of  FIG. 6 , a book  4  is placed in the appropriate compartment or receptacle  23  in one section of the package and a ROM cartridge  10  is inserted into compartment  37  in the other section of the container. Section  17  of the package is then pivoted about the hinge and spine  21  and is forced into mating frictional engagement with the other section  19 , closing the package.  
         [0071]     The sections of the package may then be secured by a sealing device to prevent a customer from tampering with the product at retail. In one embodiment the sealing device may be a strip of plastic tape  40 , shown in  FIG. 3 , which is then placed along one or more edges at which the two sections  17  and  19  abut to provide a tamper evident seal. In alternative embodiments the two edges of the sections may be tacked with glue, provided with an ultrasonic weld, sealed with an ultra-violet sensitive or sealed with a heat sealing compound, all of which fall within the scope of the invention. As example, referring to  FIG. 6  dots of ultra-violet sensitive glue or heat sealing component may be placed at the four corners of shoulder  33  in section  17 . The section is folded over into mating engagement with section  19 , enclosing the product components. Then the dots on the shoulder is exposed to UV light or heated in a heat chamber, depending upon which sealing material is employed. The dots then harden and fasten the two sections together. To access the package, the consumer need only insert a knife at the location of each dot and cut the bond at those locations. The sections may then be pivoted apart. As one appreciates, that is much simpler than when opening present clamshell type packages.  
         [0072]     Gluing may be used as a less preferred alternative to heat sealing for permanently attaching the paper board to the plastic material, in which case a thin layer of transparent glue is applied to the printed paper board. Then the board is properly aligned on the plastic material of the package and pressed into place on the plastic material. Any convenient known transparent glue conventionally used in plastic to paper board attachment in packaging may be used.  
         [0073]     The drawings of the section view of  FIGS. 7 and 8  and those which follow in this specification are not to scale, particularly the thicknesses of the paper board material  9  and the plastic  11 , the latter of which typically is greater in thickness. Reference is made to  FIGS. 9, 10  and  11 , which are sections taken along the lines  9 - 9 ,  10 - 10  and  11 - 11 , respectively, in  FIG. 1 . As is evident from the section view of  FIG. 9 , when the package is closed the shoulder  33  and  35  of section  17  frictionally mate with the corresponding shoulders  27  and  25 , respectively, of the other section  19 . The openings and deep depressions in the surface of plastic  11  underlying paper board  9  produced when hollow shoulders  33  and  35  and shoulders  25  and  27  and the hollow shoulder to pocket  37  were formed in the thermoforming process are covered over by treated paper board  9  so that the outer panel surfaces  2  and  3  are planar. The treated paper board  9  is flat and sufficiently rigid to provide a firm surface to cover those open portions of the outside surface of the two sections of the board overlying the deep indentations in the surface of the plastic material and gives the resultant structure an overall book-like or album like appearance and feel.  
         [0074]     Reference is made to  FIG. 10 , which is a section taken along the lines  10 - 10  in  FIG. 1 . This figure show the hinge configuration when the package is closed, and shows pocket  37  and the section of hollow shoulder  39  that forms the pocket. Shoulder  39  is hollow. That hollow extends through the flat base portion of plastic material  11  producing a deep depression and opening in the surface that is covered over by treated paperboard  9 . Reference is next made to  FIG. 11 , the section view taken along the lines  11 - 11  in  FIG. 1 . The protruding wall  8  of recessed window  5  is shown to penetrate from the one housing section into the other housing section, leaving clearance for the thickness of the intended book. The window forms a depression (e.g. opening) in the flat base portion of the plastic material.  
         [0075]      FIGS. 12 and 13  are enlarged partial section views of the spine  21  and hinges  43  and  45  with the package, respectively, open and closed. The hinges are shown to be of an inverted rectangular U-shape in cross section. When the book is closed, the stems of the U-shape should squeeze together slightly. The scoring  44  and  46  in the paperboard material  9  is aligned with the hinges. Note is again made that the paperboard material, although bound to spine  21 , is not bound to the plastic hinges  43  and  45 . Reference is made to  FIG. 14  which is a partial view of the spine and hinges taken along the lines  14 - 14  in  FIG. 6  looking down on the spine. The hinges extend linearly forming an inverted rectangular channel along the spine of the container hingedly joining the spine to each of sections  17  and  19 . As one appreciates the shape of the hinges is new and is particularly effective when joining the album type sections so that the sections can be pivoted close to the book-like configuration when the sections are formed of any of the plastic materials, including PVC, earlier described.  
         [0076]     The foregoing embodiment contained a recessed window  5  that pressed into contact with book  4  when the package was assembled with the product inside and closed. As those skilled in the art appreciate in other less preferred embodiments that do not require that feature a recessed window need not be included and only windows that are co-planar with the section surface, like window  7 , would be used. In still other less preferred embodiments one may elect to include a single window or in still other embodiments, eliminate windows entirely. Such an embodiment is illustrated in the not-to-scale-views of  FIGS. 15-21 , next described.  
         [0077]     The combined package and storage album  50  of  FIG. 15  is designed to hold a two-component product that consists of a ROM game cartridge  60  and an interactive book  62 . The package and storage album and is shown laid open with a game cartridge  60  and the interactive book  62 , containing game instructions and information, are shown in withdrawn positions, removed from storage album  50 . When the album is closed, housing sections  51  and  53  are in mating frictional engagement, confronting one another, and from the bottom side appear as in  FIG. 16 , and in perspective as in  FIG. 17 . As shown in the cutaway in  FIG. 17  the side of the album is formed of a layered structure containing transparent plastic layer  64 , that forms a thermoformed shell structure containing all the formed plastic elements shown in  FIG. 15 , a second transparent plastic sheet  68  forming a side wall of the album, and a paper board sheet  66  containing printed matter, text  67   a  and graphics  67   b , on both sides, that is visible through the transparent plastic. Those elements are described more fully in the description that follows.  
         [0078]     Continuing with  FIG. 15 , album  50  contains two housing sections,  51  and  53 , pivotally joined together by a spine  52  and two mechanically formed hinges  54  and  55 . A hanger  56  is integrally attached to an upper end of housing section  53 . That hanger contains an opening  57  to enable the package, filled with product and closed, to be rack mounted for retail sales display. The walls of the storage album are formed of transparent plastic, preferably polyvinyl chloride.  
         [0079]     A rectangular sheet of printable opaque material  66  that is easy to bend or fold, suitably thin cardboard or paperboard, underlies and most of the transparent plastic walls of the two housing sections and the spine, which, overall, is of a like rectangular shape as the paperboard sheet. The paperboard sheet may contain coloring and contains advertising material in both text  67   a  and graphics  67   b , only some of which is labeled and which is only partially illustrated. That printed material is visible through the overlying transparent plastic material. The opposite side of that paper board sheet also contains like kinds of printed matter, both text and graphics, which is also visible to view through a plastic backing layer  66 , later described.  
         [0080]     A shallow rectangular pocket or well in the interior of housing section  53 , framed by a peripherally extending upstanding wall  58 , is designed to receive and frame the contents intended to be placed in that housing section, namely, book  62 . A pair of nubs  63  and  65  are located on the outside of wall  58  and extend outwardly a short distance. When the album is closed the nubs press into the wall of the other housing section to enhance the frictional contact between the two housing sections.  
         [0081]     A pocket or receptacle  59  is located on the inside surface of housing section  51  and is designed to frictionally hold cartridge  60 , a semiconductor ROM plug-in cartridge, in place. Pocket  59  is formed by a raised shoulder, integrally formed on the inside surface of housing section  51 , that extends in a closed loop. The inside surface of the shoulder defines a region that is of the same essential geometry of the of cartridge  60 , but is slightly larger in size sufficient to create a tight fit with the cartridge. The hollow walls of that shoulder, integrally formed of the same thin plastic material as other portions in the upper portion of the package, exhibits sufficient flexibility to capture and grip the cartridge when the cartridge  60  is pressed into the receptacle for storage, and, thereafter, frictionally holds the cartridge in place.  
         [0082]     Further, two depressions  61  at diametrically opposite locations in that shoulder of receptacle  59  define finger holes that permit the user to grip cartridge  60  from the side with two fingers and pull the cartridge from the receptacle.  
         [0083]     Although the foregoing embodiment is intended for use with a two component product and contains only a single receptacle in the one housing section, the reader is reminded that the invention is not limited to that number of receptacles. As those skilled in the art appreciate, in other embodiments of the invention intended to package a multi-component product that contains a greater number of components, additional receptacles of the foregoing type (and additional windows associated with those additional receptacles may be formed in the section to hold (and display) those additional components.  
         [0084]     Preferably the height of the walls of receptacle  59  is less than the height of the surround outer raised shoulders of housing section  51  so that when housing sections  51  and  53  are pivoted into a mating frictional engagement closing the album to confine the multiple components of the product, the upper edge of the wall defining receptacle  59  in housing section  51 , ideally, should press against a surface of the book  62  located in the confronting housing section  53  to minimize potential rattling within the closed package.  
         [0085]     It may be difficult to understand the physical relationship of the flat opaque sheet of printed material  66  referred to with the remainder of the structure without first considering the process of manufacturing package  50 . For that description, reference is made to  FIG. 18 , which illustrates an intermediate stage of assembly of the package structure. The principal constituent of the two housing sections  51  and  53  and spine  52  in  FIG. 1  is the single piece thermoformed transparent plastic shell  64  illustrated in  FIG. 16 . The foregoing structure  64  is thermoformed formed to the shape illustrated in this figure and in  FIGS. 17 and 18  from a sheet of plastic using known conventional thermoforming technology, not illustrated. The resultant shell structure  64  and its walls are quite flexible. As shown, shell structure  64  defines the two housing sections and spine, the interiors of those housing sections, the outer walls, and other elements of the album above described and illustrated in the figures. In one specific embodiment, the walls of shell structure  64  are about 0.012 to 0.015 inches thick, that is twelve to fifteen thousandths.  
         [0086]     A thin sheet of paper board material  66  is placed over the rear of shell structure  64 , covering most, but not all, of that rear surface. Paper board sheet  66  is pre-printed with the desired text and graphics on both the front and back surfaces. Paper board sheet  66  is thin, about one mil thick in one specific embodiment, and can be easily be folded or bent over. The sheet is placed over the back side of the structure  64  and fitted in place in that structure within a shallow molded receptacle on the back side of the shell structure that serves as an assembly guide to center sheet  66  in the shell and provide a shallow receptacle to receive the paperboard sheet.  
         [0087]     Continuing with  FIG. 18 , some of the printed matter on both front and back sides of the paper board sheet overlies both housing sections  51  and  53  and spine  52  in the formed container  50 . Paperboard sheet  66  is of a rectangular shape that is slightly shorter in length and width, and, hence, area, than the corresponding rectangular dimensions of shell structure  64 . When centered on the rear side of shell structure  64 , paper board sheet  66  leaves a narrow peripherally extending annular strip of shell  64  exposed.  
         [0088]     Next, a flat sheet of thin transparent plastic  68  is placed over the paperboard sheet  66  backing the rear of the plastic shell structure. That flat sheet abuts against the rear side of paperboard  66  and contacts the back side of the plastic shell structure along a peripherally extending frame or rim. Plastic sheet  68  is of a rectangular shape that is the same shape rectangular shape as that of the rear of plastic shell structure  64 , but is slightly larger in both the length and width dimensions, and, hence, in area. Those larger dimensions result in an annular ribbon-like surplus that extends about the periphery of plastic shell  64  when the sheet is centered on shell structure  64 .  
         [0089]     Brief reference may be made to the section view of  FIG. 20 , which shows the relationship between the plastic members  64  and  68  and the cardboard  66  along the outer periphery, but in an inverted position from that of  FIG. 18 . The peripheral rim portion of plastic shell structure  64  is elevated from the central portion to form a shallow receptacle in the central portion of the rear side and the paper board sheet  66  is located in that receptacle. Flat plastic sheet  68  is in contact with that rim portion of the plastic shell structure. In the specific embodiment referred to the thickness of this sheet is about six mils. Continuing with  FIG. 18 , as the three pieces are thus assembled to this stage, the assembly is placed in an RF heating device or station, not illustrated.  
         [0090]     The RF heating device is designed to produce heating and partial melting of the plastic material all about the periphery of the assembly and subsequent cooling fuses the contacting plastic sheets together along the line of contact. The RF heating also cuts through the plastic backing sheet, except in the peripheral position of the hanger  56 , illustrated in  FIG. 15 . At the location of the hanger the heating apparatus is designed to define the shape of hanger  56  and cut through the plastic sheet to provide the outline of the hanger and cut through and produce the opening  57  in that hanger. With the RF energy heating the edges of the two plastic parts melt and fuse together. That produces a permanent seal between those parts, once the heating energy is terminated. Following termination of the RF energy, the now unitary assembly is removed from the RF heating apparatus, and the peripheral strip is manually detached from the plastic backing sheet  68  during the procedure and discarded. The completed integrated structure is then placed in a staging area for filling with product, closing and sealing the filled package closed with sealing tape. The foregoing fusing operation can be accomplished in about five seconds.  
         [0091]     The not-to-scale section view of  FIG. 19  illustrates the foregoing assembly in great part, with a bottom side, including the plastic backing sheet, that is greatly enlarged in scale relative to the remaining parts of the assembly. The outer edge of the assembly is better illustrated in the section view of  FIG. 20 , which is taken along the lines  20 - 20  in  FIG. 19 . As shown, paper or paperboard sheet  68  stops short of the outer edge and is smaller in dimension than both shell structure  64  and plastic backing sheet  66 . The outer bottom edge of the rear side of the shell structure  64  contains a raised shoulder or rim. That raised rim extends peripherally about the rectangular backside of the shell structure to define a frame or guide, earlier referred to, in which to place the printed paper sheet  68  during the assembly described in connection with  FIG. 16 . Moreover the edge of that shell and the peripheral edge of the flat plastic backing sheet  66  are placed in direct contact. That permits the peripheral edges of the two plastic components to be directly fused together by the RF heating apparatus (as earlier described) without any interference from paper sheet  68 .  
         [0092]     Returning again to  FIG. 18 , on completion of the assembly procedure described, it is seen that the paper board sheet  68 , the plastic backing sheet  66  and the shell structure  64  remain relatively flat in the region of spine  52 , and, more specifically, in the junctures between the spine and the respective housing portions  51  and  53 . That is, no hinges have as yet been formed, and none of the sheets were scored to aid in folding as occurred in the prior embodiment of  FIG. 1 . As becomes apparent scoring is not required.  FIG. 19 , to which reference is made, illustrates the section of  FIG. 15  after the album-like package is initially closed (and reopened), whereby a pair of longitudinally extending permanent creases (e.g. hinges) of a slight U-shape section shape are formed in the plastic sheets  64  and  68  and in the paperboard, thereby defining hinges  54  and  55 . Those hinges are illustrated in enlarged scale in  FIG. 21 , which is a section taken along the lines  21 - 21  in  FIG. 19 . In effect, the hinges  54  and  55  are manually mechanically formed on the initial closing of the package.  
         [0093]     The final step in the packaging is to place strips of bonding tape over the slit between the two housing sections to permanently prevent the two sections from being opened prior to customer purchase. The sections of the package may then be secured by a sealing device to prevent a customer from tampering with the product at retail. The preferred seal in this embodiment is one or two strips of plastic tape  70 , one of which is illustrated in  FIG. 16 , to provide a tamper evident seal. A strip of the tape is placed along a slit and extends a short distance around the corner of the album. The second strip extends around the opposite corner, but is not visible in this view.  
         [0094]     The preferred plastic material used in the embodiment of  FIG. 15  is polyvinylchloride (“PVC”). However, it should be understood that other less preferred plastic materials may be substituted. Thus the term plastic or plastic material should be construed to include not only PVC, but also polypropylene, polyethylene (“PET”), polystyrene and any other equivalent material that gives the housing sections a slightly stiff, yet flexible, form and is used for packaging, whether existing or that may be developed hereafter.  
         [0095]     As one appreciates, the paper board sheet in the foregoing embodiment completely covered both sections, preventing the customer from viewing any portion of the product, which remains unaccessible. Should the manufacturer wish, however, to allow visual inspection of a portion of the product in situs in the package as in the prior embodiment, suitable openings may be located in the paper board sheet to form windows and those openings would be die cut out of the paper board sheet prior to the assembly procedure described in connection with  FIG. 18 . Die cutting of windows requires extra steps in manufacturing and, hence, increased labor costs. If cost containment is a requirement, then the incorporation of windows in the package would be less preferred. Moreover, the assembly of this embodiment avoids any need to coat the paper board sheet with an adhesive, saving additional labor and supply cost. As another advantage, no extra steps are required in this embodiment for the formation of the creases or hinges that permit the housing sections to be closed, and then, repeatedly opened and closed. The act of closing the package which occurs in all embodiments mechanically forms the hinges. That technique also saves labor and, hence, labor costs, and is preferred.  
         [0096]     It is believed that the foregoing description of the preferred embodiments of the invention is sufficient in detail to enable one skilled in the art to make and use the invention. However, it is expressly understood that the detail of the elements presented for the foregoing purpose is not intended to limit the scope of the invention, in as much as equivalents to those elements and other modifications thereof, all of which come within the scope of the invention, will become apparent to those skilled in the art upon reading this specification.
