Abstract:
A disposable shippable display apparatus for use in displaying products, samples, premiums, messages or the like comprises an inner sleeve containing products, samples, or the like, slidably located within an outer sleeve and configurable between a closed or an open position. After shipping the display apparatus to its end destination in the closed position the display is easily and quickly user deployed by moving the inner sleeve to the open position, where multiple catches and supports lock the inner sleeve in an immediately useable display configuration. The products and samples are now in full view for consumption by patrons and customers.

CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims a priority benefit from a provisional patent filing, Application No. U.S. 60/875,225, filed on Dec. 16, 2006 in the United States Patent and Trademark Office, and titled “Slide and Lock Display System”. 
     
    
     STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT 
       [0002]    Not Applicable. 
       FIELD OF THE INVENTION 
       [0003]    The point-of-purchase industry continuously struggles with creating displays that serve the needs of the manufacturers as well as the needs of the retailers. 
         [0004]    It is well known that most displays require set up, and many displays to a varying degree take more time to set up than what the retailers and/or the manufacturers would like. Set up time means money to them. Further, displays that take too long to set up may be improperly set up, or may be perceived as too difficult to set up and may never see the light of day. 
         [0005]    Although decisions to spend millions on displays are made at high levels, the set up of a display is made by low-level store associates. If the display is not set up, or the product is removed from the display and placed on the shelf for presentation, the money spent on that display is wasted. 
         [0006]    News America Marketing, one of America&#39;s largest merchandising companies offers manufacturers a display building service where 4000 of their merchandisers out of 26 offices will visit stores under contract to ensure their clients displays get properly set up. In their sales pitch they claim that nationally only about 50% of all displays that ship to a store ever get set up. Their merchandising services group ensures a significantly greater success rate of deployment. Of course this service does not come cheap. Floor displays may cost between $5 and $40 to produce, and a merchandiser&#39;s visits may cost upwards of $20 per visit to set up a display. When the scale is thousands of stores, and millions of displays, ensuring compliance by using an outside service can get very expensive. 
         [0007]    For the purposes of this application the inventor would like to focus attention on a very specific style of floor display. One made up of a separate Product Tray and a separate Display Base. During shipping and storage the Product Tray will often, but not always, travel inside the Display Base, referred as the “closed” position, and once in-store the Product Tray will sit on top of the Display Base, referred as the “open” position. 
         [0008]    It is important to note, that although the focus of the application will be floor displays used in a retail environment it is the intent of the inventor that the invention described in this application has many other useful applications where this structure is not limited by size. Uses may include storage boxes, dispensers for candy, food and beverage, toys, pop-up greeting cards as well as a multitude of items where moving from a closed to open position quickly and easily is desirable. It is also important to note, that the invention may operate in a manual, semi-automatic, or fully automatic mode. 
         [0009]    Millions of displays are shipped each year in a closed position, requiring store personnel to take time from other important store activities to set up a display. With more and more pressure on their time, retailers are insisting that marketers create pre-packed displays that are easy to set up, or as in many cases, they will require that the displays are shipped ready-to-sell, requiring no set up. Shipping a display that requires no set up is devastating to marketers, as this means that the display must travel in a fully assembled or open position, in its most inefficient shipping configuration. This also means that the display will need additional parts to ensure that it arrives intact, and most importantly it means that the displays will cost significantly more to make and ship, as displays that ship in the open position are much larger than ones that ship in the closed position. Less displays per pallet means it will require more trucks to deliver the same number of displays. More trucks means more gas, and more CO 2  emissions released into our environment means a greater negative impact on our already stressed natural resources. 
         [0010]    Wal-Mart, the world&#39;s largest retailer has announced that it is embracing a-massive effort to reduce the size of packaging and displays so that products are shipped more densely and more efficiently to the stores requiring less trucks, which in turn will require less fuel, resulting in less emissions and less pollutants into our environment. 
         [0011]    It is to everyone&#39;s advantage to produce temporary, semi-permanent, and permanent display structures that ship in closed positions and can easily and quickly move to the open position. Further, it is desired that these displays are easy to manufacture, to pack out, to store and to ship. 
       BACKGROUND OF THE INVENTION 
       [0012]    One of the ways that marketers have learned to address the problem is by sticking to display constructions that are well known in the industry. Familiarity by the end user with the display configuration goes a long way to ensure that a display is set up. One traditional floor display structure is compromised of a Product Tray that displays the product with a separate folded and/or collapsed Display Base. Once this display arrives, the retail associate lifts out the Product Tray, places it on the floor while the Display Base is folded into a structure that will hold the Product Tray, then the Product Tray is lifted and placed on the assembled base ready for customer presentation. 
         [0013]    Marins, a French company markets a folding display, called the LAMA. It takes seconds to deploy and uses a rubber band mechanism to self construct. LAMA displays are now sold in more than 90 countries worldwide. This display does not come cheap, and is of limited use for those marketers seeking displays that hold product. It is more of a visual display than a shipper or product display. The base construction can hold a limited amount of weight without having to add a significant amount of parts which significantly increase the cost of the display and require much more time to assemble in-store. Also relying on rubber bands is an unpredictable proposition, since they may break, and/or lose their elasticity over time. 
         [0014]    Another floor display structure includes a product tray that ships inside its base. First, the store associate pulls the product tray out of its base and places the product tray on the floor. Next, the base is turned upside down and the product tray is carefully lifted placed on top of the upside down base. Although this structure seems simple, there are some drawbacks. First, because the product tray and the base are separate pieces the base can easily be misplaced leaving their product tray without a base to sit on. Further, even if the display is set up and because the product tray simply sits on the base, and is not locked in any way, it can easily be “bumped” where the product tray and the base are left out of alignment creating an awkward look or in the case of heavy products, a dangerous situation, prone to spillage. It is also possible that the product tray will be removed from the base, as store personnel are constantly moving around displays to better serve their customers. 
         [0015]    To minimize the problems described above there is a similar well known construction that has a base that is not turned upside down to hold the product tray, but rather includes a set of die-cut “push-in” tabs on each of the four corners of the base. When these tabs are pushed in they form a mini ledge that is designed to hold the product tray inside of its base, preventing the product tray from sliding down or sliding off the base if it is bumped. This structure still requires the product tray to be pulled out of the base and placed on the floor, while the “push-in” tabs on all four sides of the base are activated to create the mini ledge for the product tray. To complete the display the store associate lifts the product tray and carefully positions it to fit inside the base so that it can sit on top of the push-in tabs. Although this does not sound like a lot of work, many that use this structure will say that as easy as it sounds these displays are not always set up, or are improperly set up. The product tray and the shipper are still separate items so the same problems exist, that during the life of the display, the product tray may be separated from the base. Another drawback to this structure is that the full weight of the product tray is placed on the “push-in” tabs. Since the “push-in” tabs are cut from the base, they will not be able to accommodate heavy loads. Also, if the product tray is large or heavy, a single store associate may not be able to place the product tray on the base by themselves and may require additional help, tying up other store associates. Another version of this display, has a separate crisscross insert that may be placed inside the base to help hold heavier products. Although better than push tabs, it still requires significant set-up effort. 
         [0016]    The Autoshelf is an automatic display system that slips out of its shipping carton and unfolds open ready to use. This system also uses rubber bands to deploy the display, one of their advantages over LAMA display described earlier, is that the Autoshelf is designed to hold product. Although the Autoshelf holds products, a major disadvantage is that it also ships “flat” and separate from the product it is designed to hold. The store associate has to find the “flat” Autoshelf display and deploy it. Only then can the store associate begin stocking the Autoshelf display with product. Often, from the marketer perspective, this is asking too much of the store associate and a pre-pack shipper is preferred. Further, a store associate may receive the shipment, open the product carton and not ever be aware that there is a “flat” unfolded display to set up and may simply proceed putting the product on the shelf, without ever realizing that a separate shelf display even exists for the product. Once the Autoshelf display is set up, the store associate still needs to load the display, taking valuable time away from serving customers or other necessary store activities. Another problem with Autoshelf is that it ships in a separate container than the product it is designed to hold. This creates additional shipping costs. Yet another problem, same as in Marin&#39;s LAMA displays, the Autoshelf uses rubber bands which will lose elasticity over time and can break prior to or during deployment. Finally, the Autoshelf structure requires a certain assembler skill level as the placement of rubber bands is more elaborate and more expensive than displays that do not rely on rubber bands for deployment. 
         [0017]    Many have tried to create automatic bases that set up when a product tray is lifted out of it. One such display uses a rubber band mechanism that makes two pieces of paperboard snap to an “X” shaped support when the product tray is lifted past the height of the “X” support. The same problems exist here, rubber bands may lose their elasticity, and/or fail to deploy. 
       BRIEF SUMMARY OF THE INVENTION 
       [0018]    Against the foregoing background, it is the primary object of the present invention to provide a display having a closed position for efficient shipping and storage, and upon arrival at an end destination quickly and easily sets up to an open position for display. 
         [0019]    It is yet another object of the invention that deployment from closed to open position takes only a few seconds. 
         [0020]    It is yet still another object of the invention, to provide a display that is considered a one piece display requiring no assembly of parts, for easy portability and set-up. 
         [0021]    It is also the object of the invention to create a display that after assembly ships as a single unit, where the product tray and the base are in an interlocked relationship, so that the product tray and the base can not be easily separated from each other. 
         [0022]    It is another object of the invention to create a display that deploys from a “closed” position to an “open” position without the use of rubber bands. 
         [0023]    It is yet still another object of the present invention, to provide a display that allows for the product trays to be assembled and filled with product, then stored inside the base so that the display ships fully loaded, and requires in store stocking. Also, this structure will allow the product tray to be stored separately from the base of the display, prior to final assembly and shipping, offering yet more flexibility in fulfillment options. 
         [0024]    It is but another object of the present invention to provide a display that allows for separate shipment of the bases, and separate shipment of the product trays so that the bases, may be manufactured in a separate place than the product trays, creating many more fulfillment options for the manufacturer. For example the product trays may be densely packed and shipped from China, while the bases may be produced locally, and the final assembly of bases and product trays could also be done locally, saving money on shipping of bases over great distances, and keeping part of the manufacturing in local economies. 
         [0025]    It is another object of the invention to provide a display with a substantially flat profile that can be stored and shipped efficiently, and easily assembled at a future date. 
         [0026]    It is the object of the invention to create a unique internal locking shelf structure that allows the product tray to be pulled in an upwards motion until it reaches a “locked” position within the base of the display leaving the product tray fixed at a predetermined height, as it rests on the internal shelf. 
         [0027]    It is but another object of the present invention to ensure that when the product tray arrives at the “locked” position within the base, it may not be pulled further out of or completely from the base nor can it be pushed back into the base unless the structure is deliberately “unlocked”. Once “unlocked” the product tray may be easily lowered or slid back into the base for future deployment. 
         [0028]    It is yet another object of the present invention to simplify the store associates experience in setting up the display. First the store associate places their foot inside a “foot slot” at the back of the closed display base and simultaneously lifts the product tray straight up until the “locked” position is reached. To the delight and surprise of both marketers and retailers, alike, the total time to deploy this display from “closed” to “open” position is five seconds or less. 
         [0029]    Another object of the present invention is that the product tray structure may be formed into any tray style including but not limited to: dump bin; shelf style; hanging hook; or stacking product style. 
         [0030]    It is yet another object of the present invention to create a display structure for use with heavy products. It is well known that major retailers recommended floor displays designed to be set up by a single store associate should not exceed forty pounds. When the product tray is ‘heavy’ (over forty lbs.), two people are required to lift the display, and the structure is modified to include two “foot slots”, one on each of opposite sides of the display so that each person can use their foot to hold the display in place as they lift the product tray into the “locked” position. For single person deployment of a ‘heavy’ product tray, an alternate embodiment is the inclusion of a spring, lever or similar force reduction mechanism to reduce the force required to the forty pounds or less level. 
         [0031]    It is yet another object of the present invention that the display can be made any reasonable shape or size preferred by marketers or allowed by retailers. The size or shape can vary from a small counter top unit to approximately a full shipping pallet display. 
         [0032]    It is but another object of the present invention to create a display that can be made from multiple temporary, biodegradable, semi-permanent and or permanent materials. Although the preferred embodiment is to use paperboard for construction, the invention may also be fabricated from wood, plastic, metal, or other well-known permanent display materials. 
         [0033]    It is but another object of the present invention to modify the materials used in the internal structure to best support and deploy the display depending upon on the weight of the product tray, and or the display&#39;s end use environmental climate. The internal support mechanism may be made from plastic to ensure that the internal mechanism springs into action during deployment even under extremely humid conditions. 
         [0034]    It is another object of the invention to vary the locking mechanism, to suit the needs of the product tray. The key is that there is always a shelf structure that deploys when the product tray is lifted past a certain predetermined point, and if desired, a lock that prevents the product tray from being lifted out of its base. 
         [0035]    It is but another object of the present invention to use the same structure for smaller products and displays such as countertop and shelf displays, as well as toys, greeting cards, expanding shelf trays and a myriad of other displays and products that could benefit from such a locking mechanism. 
         [0036]    It is further the intent of the inventor to use this structure in products where a closed and an open position are desired. One such application would be a personal home Halloween candy dispenser that is sold in store in a closed position to save on shipping costs and storage space by the store, and when brought home is easily deployed to an open position ready to provide candy to eager trick-or-treaters. 
         [0037]    Another home application would be a beverage dispenser that is purchased in a closed position again for the shipping efficiency and deployed at home to an open position ready to dispense the beverage of choice. Another feature of the invention within this and other similar applications is that the display base when deployed, or in the locked position is empty and can be fabricated with a deliberate flap or door opening so as to become a receptacle for empty beverage containers, a fringe benefit of the structure. 
         [0038]    It is further the intent of the inventor to use alternative modified structures to hold the product tray in the locked position. Although the preferred embodiment requires separate folded structures deliberately placed inside the base, another solution would utilize a modified base combining the base and locking mechanism in one continuous piece of paperboard or other material.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0113]    Referring to the drawings and, in particular to  FIG. 1 ,  FIG. 2  and  FIG. 3  thereof the display with a slide and lock structure of the present invention is provided and referred to generally by inner sleeve  1 , base  3  and ledge  2 . (Please note the terms ‘product tray’ and ‘inner sleeve’ are interchangeable, and similarly the terms ‘base’ and ‘outer sleeve’ are interchangeable as well.) The simple display structure may be made from paperboard, plastic, or any combination of substrates that would form a suitable inner sleeve and base to be used for display purposes. 
         [0114]    It is further the intent of the inventor, to make the inner sleeve  23  and base  24  from other more durable materials for semi-permanent and permanent displays. This change in substrates may be desired for a more elegant look, or for a more durable structure. The materials for this alternate display structure may include but are not limited to plastic, wood metal, and other well known display and fixture materials. 
         [0115]    In the preferred embodiment the slide and lock display would have an inner sleeve  23  with a single catch tab  9 , a single base  24  with a single catch tab  18  and ledge  2  made from paperboard or plastic. Although the ledge made from foldable paperboard, such as corrugated board, is the preferred embodiment, in certain instances it may be preferred to use plastic or other suitable, foldable material that could be formed into a ledge. There also may be instances where a solid inner sleeve  23  and base  24  may be preferred such as injection molded plastic, as often in today&#39;s competitive retail environment more and more temporary displays are combining paper board and plastic to achieve highly stylized effects. 
         [0116]    In the preferred embodiment the display base would have a bottom  27 , either tuck flap  19 ,  20 ,  21 ,  22  or an auto bottom (not shown) or a bottom that is glued or taped. An auto bottom refers to a well known packaging closure that requires no tuck flaps, but is glued and folded in manufacturing so that it sets up without the need to tuck flaps in order to assemble the structure. However, the bottom is not necessary if a separate ledge structure is added by gluing it to interior of panel  17  (not shown) so that it would have the same height as panel  12  when it supports inner sleeve from sliding back into the base. Many of the new specialty gluers are able to add separate structures in position and in line without a separate operation and without slowing down the manufacturing speed. 
         [0117]    Another way to add a ledge would be with specialty gluers that are now able to automatically glue separate tabs (ledge) to inner panels at high speeds. A less desirable but effective way to create the ledge is by creating a ledge by cutting and folding a tab from panel  17 . This is less desirable because it would not automatically lock. Also the cut out left by folding the ledge tab makes the display look less desirable. The inventor acknowledges that although these alternate options would require less parts and would cost less to produce, that most available machinery is not suited to these tricky gluing options. The preferred embodiment would make the slide and lock display easy to manufacture by the broadest audience, that would mean that the ledge remain a separate part. The inventor further acknowledges that in high volume situations, it would be more desirable to make the display from only two parts rather than three parts, as assembly of two parts would take less time than the assembly of three parts. These are some of the considerations one must decide to determine which embodiment is preferred as different applications have different requirements. 
         [0118]    In the preferred embodiment the ledge  2  is a flat structure that is made from flexible material that is folded on fold lines  33  &amp;  36  to create a spring action created by the memory in the material being used. It is important to note that the material being used for the ledge must be suitable for the weight of the inner sleeve. For example if the display is a greeting card, or if there is little pressure from the base as in a slide and lock display that has a horizontal application such as a shelf tray  FIG. 50  then the ledge may be made from lightweight material as the inner sleeve and base. If the use is to hold heavy material, then the ledge must be made from stronger, more suited material. If the display will be in a humid or wet environment, or will be in storage for long periods of time then a more resilient material needs to be used for the ledge. 
         [0119]      FIG. 5  is a cutaway side view that shows how the slide and lock mechanism works. In the first illustration  29  inner sleeve  23 , is collapsed inside the base  24 , panels  10 ,  11  and  12  of ledge  2  are compressed between exterior of inner sleeve rear panel  6  and interior of rear base panel  15 , as are catch tabs  9  and  18 , panels  10 ,  11  and  12 . The memory, created in the flexible material, from the compression puts the ledge into a spring-like state ready to expand once it has the space to do so. In illustration  30  bottom  34  of inner sleeve  23  travels past fold  11  allowing tab  18  to snap away from exterior of panel  6  and slide under tab  9  nesting between the rear of tab  9  and interior of panel  15  forming a lock and not allowing the sleeve to slide out of the base. As the inner sleeve  23  moves past fold  11 , ledge  2  is pushed into an extended position into open cavity  35  by the memory stored from the compression of panels  10 , 11  and  12 , forming a ledge  11  upon which bottom  34  of inner sleeve  23  can rest as shown in illustration  31 , preventing it from sliding back into base  24 . It is important that inner sleeve  23  and base  24  fit snug so that the contact between exterior of front panel  8  of inner sleeve  23  and interior of front panel  17  of base  24  is enough to keep the display from leaning forward or falling out. Depending on the use of the display it may be necessary to enlarge the amount of contact or overlap between these surfaces as shown in  FIG. 4  at  32 . It is also important that the fit on the opposite sides is also snug but not too tight as to obstruct the movement of the inner sleeve  23  inside base  24  as it moves from closed to open position. Also if the fit is too loose the locking mechanism will not properly engage. 
         [0120]      FIG. 6  is a cutaway side view showing how the slide and lock mechanism may be used to create taller structures, by adding a second inner sleeve  6 B that locks into inner sleeve  6 A or  23  making the display three tiers tall. It is also important to note that an additional optional panel  38  has been added to ledge panel  12 . This panel will ensure that panel  12  remains at the intersection of bottom  20  and panel  6 A of inner sleeve  23 . Panel  38  was also added to base  24 . It is important to note that if inner sleeves  23  and  39  do not have bottoms  20  then the lower edge of panel  6 A or  6 B would slide down and rest on fold  36 . 
         [0121]      FIG. 7  shows how this display structure has a closed position  40  and open position  41 . The inner sleeve  23  may be custom die cut  43 . It is the intent of the inventor to use this structure as a retail display, where an opening in base  24  allows for the presentation of product  44  (see  FIG. 8 ), and inner sleeve  23  serves as a display header. It is also the intent of the inventor to use the structure as a toy.  FIG. 9  is an example of a puppet theater where the inner sleeve  23  has a window cut out to serve as a stage. 
         [0122]    In addition to the preferred embodiment described above, the slide and lock display structure has many useful applications as a weight bearing display.  FIG. 10  features one such structure consisting of three parts an inner sleeve  100 , a double ledge with foot-bridge  200 , and a base  300 . 
         [0123]      FIG. 12  introduces a double ledge with a foot-bridge  233  with foot entrance  235 .  FIG. 14  shows the assembly of the inner sleeve  100 . Panel  117  folds over and glues to glue tab  116 .  FIG. 17  shows the inner sleeve  100  is fully assembled.  FIG. 18  shows the partial assembly of the double ledge with foot-bridge  233 , and  FIG. 19  shows base  300  of  FIG. 13  to complete the slide and lock display. It is the intent of the inventor to vary the style, material and construction of the double ledge panel  200  to adequately support the product weight placed in inner sleeve  100 . For examples as the weight in inner sleeve  100  increases, reinforcing panels  212 ,  213 ,  210 ,  211 ,  216 ,  217 ,  218  and  219  may be added to panels  203  and  207 , as shown in  FIG. 41 ,  FIG. 42  and  FIG. 43 , to create more weight bearing strength. Adding those panels will also create more spring tension in deployment of the double ledge. 
         [0124]      FIG. 16  shows a perspective view of an assembled double ledge of  FIG. 18  being inserted into base  300 . Note reinforcing panels  212 ,  213 ,  210 ,  211 ,  216 ,  217 ,  218  and  219  are placed in an accordion fashion so as to create maximum tension and spring.  FIG. 20  is perspective view of inner sleeve  100  of, double ledge  200  and base  300  of  FIG. 10  fully assembled. 
         [0125]      FIG. 21  shows the inner sleeve catch tabs  103  and  104  moving from its original DOWN position to its loaded UP position. This is done by folding catch tab  104  on score  102  and catch tab  103  on score  101 , and sliding the inner sleeve inside the base. The inner sleeve  316  shown in  FIG. 22  works the same as inner sleeve  100  except it is designed to hold stackable product. The catch tabs  103  and  104  are kept in the UP position because the space between the interior base panel&#39;s  302  and  304  of  FIG. 13  and the exterior inner sleeve panel&#39;s  118  and  120  of  FIG. 11  is deliberately too narrow to allow for the free movement of the catch tabs to naturally move to the DOWN position, while at rest or while in motion when the inner sleeve is pulled up from the base. 
         [0126]      FIG. 24  shows a perspective view the inner sleeve of  FIG. 22  sitting inside base  316  which is shorter than the inner sleeve. It is the intent of the inventor to allow the inner sleeve to be taller than the base to achieve taller structures if desired.  FIG. 25  shows a foot  1201  being inserted into the foot-bridge  316  of base  300  as shown in  FIG. 13 . The inner sleeve is collapsed inside of base ready for deployment.  FIG. 26  shows pull tabs  229  and  230 . These tabs are necessary if the display needs to be retractable, if the display will deployed only once, these tabs may be removed after the inner sleeve is collapsed inside the base.  FIG. 27  shows the relationship between the foot  1201  and the hand  1202  when the slide and lock display as it is being deployed. The foot is placed inside the foot-bridge  316  to prevent the base from being raised as the inner sleeve is being pulled UP by the hand  1202  from the base. Because of the tight fit between the inner sleeve and the base, if the foot  1201  was not placed inside the foot-bridge while raising the inner sleeve, the base would also be raised. It is worth noting that it is the intent of the inventor, to use this structure in applications other than floor displays. Where instead of using a foot to keep the base from traveling with the inner sleeve when it is being pulled, that other means may also be used, including foot tabs you step on, openings or just the placement of a hand in instances where the structures are small enough. Finger openings  113  and  114  of  FIG. 11  may be replaced by other well known handles formed either from the panels of the inner sleeve, or separately attached to the inner sleeve, by glue, tabs, rivets or other well known means of attachment. 
         [0127]      FIG. 28  shows a perspective front view of inner sleeve  100  in relationship to base  300 . The top illustration shows the inner sleeve  100  sitting on top base  300  just before the inner sleeve is pushed in side the base for shipping or storage. Note that catch tab  103  of  FIG. 21  is resting on top of fold  309 , as catch tab  104  on the opposite side is sitting on fold  308  (not shown). As the inner sleeve is pushed downwards into the base, catch tabs  103  and  104  will fold upwards on folds  101  and  102  respectfully, in effect preparing the structure to perform the slide and lock mechanism. The lower illustration shows the inner sleeve  100  resting inside of base  300 . In this position, the inner sleeve  100  is resting on top of the expanded ledge  200  with catch tabs  103  and  104  facing in the UP position where the interior of catch tab  103  is in direct contact with the exterior of panel  310 , and the interior of catch tab  104  is in direct contact with the exterior of catch panel  311  (not shown). 
         [0128]      FIG. 29  shows a close up cutaway front perspective view of the right side of the engaged lock mechanism and the relationship of inner sleeve  100 , double ledge  200  and base  300  as the inner sleeve  100  is pulled up from base  300  such that catch tab  104  wedges between catch panel  311  and panel  201  of double ledge  200 . It is important to note that the same locking relationship would occur if double ledge  200  did have panel  201 . In this instance catch tab  104  would wedge between the interior of catch panel  311  and the interior of base panel  304 . It is further important to note that in the case where the inner sleeve  100  and base  300  are made from more permanent materials such as wood, metal plastic and other suitable permanent substrates, the locking tabs including catch tabs  103  and  104  and catch panels  310  and  311 , may also be made of the same materials as the inner sleeve and or base, or with mixed materials. Unlike paperboard material, the permanent materials have little or no flex so the relationship and fit between the inner sleeve  100  and the base  300  would need to be such that there would be free movement between a collapsed, or closed, position and expanded, or open, position. However, the choice of materials for the catch panels  310  and  311  and catch tabs  103  and  104  as well as the inner sleeve  100  and base  300 , in combination would need to replicate the positions shown in  FIGS. 30 ,  31  and  32 , in summary, there will need to be enough flex in the permanent materials to create the same relationships previously described. The inventor acknowledges that there are yet other options in which the positions shown in  FIG. 30 ,  FIG. 31  and  FIG. 32  may be accomplished without having flex built in the more permanent materials. One such example is to use a spring loaded hinge. Another option is shown in  FIG. 29A  where inner sleeve  100 , catch tab  104  and base  300  are made from wood. Rather than sliding the inner sleeve into the base forcing the catch tab to flex UP as it passes catch panel  311  as shown in  FIG. 21 ,  FIG. 22  and  FIG. 28 . The wood inner sleeve  100  complete with wood catch tab  104  would be placed inside wood base  300  between panels  207  and  203  of double ledge  200  of  FIG. 32 . After the wood inner sleeve  100  is fully loaded in the closed position inside base  300 , the catch tab  311 , which may be made of wood, plastic, metal or other suitable material would attached in position, as shown in  FIG. 29 , on to base  300  with screws, nails, rivets, glue or other suitable means of attachment such that when the inner sleeve  100  is pulled from base  300  it would engage with catch tab  104  creating the same lock mechanism described previously.  FIG. 33 ,  FIG. 34  and  FIG. 35  are simplified line drawings of  FIG. 29  showing the relationship of engagement of the lock mechanism from the left side of the structure. It is also possible that during the assembly process the inner sleeve is slid into the base from the bottom to accommodate non-flexible locking systems such as the wooden one described above. 
         [0129]      FIG. 36 . shows the tab lock system made from panels of the double ledge, designed to hold the compressed panels of the double ledge  200  in position while loading the inner sleeve  100 . Without this restraint the tension from the compressed panels of the double ledge would force panels  203  and  207  into the center of the base  300  cavity, making it more difficult to slide the inner sleeve  100  into the base. Another, and for certain applications, more important function of this lock tab system is to allow the structure to easily move from the open to closed position, over and over. This feature makes the structure desirable in uses where both the open and closed positions are important as in a party candy or snack dispenser of  FIG. 52 . During the party the structure is in the open or UP position. After the party, the structure is easily moved to the DOWN or closed position for storage, until the next party when the structure is yet again moved to the UP position. The lock system is comprised of lock tabs  229  and  230  that pass thru slots  220  and  221  of double ledge panels  201  and  209  and slots  306  and  307  of base  300 . In order to easily pass through slots  220 ,  221  and  306  and  307 , the lock tab has flaps  222  that may be folded to easily to pass through the slots, and when unfolded will prevent the tab from slipping inside the base due to the tension caused by the folded of the panels of double ledge  200 . Once the tabs are in a locked position and the inner sleeve  100  is in the open, or UP position of  FIG. 32 , to collapse the display one simply grabs with hand  234 , tabs  230  and  229  as shown in  FIG. 38  and pulls the tabs away from the base. This action causes the double ledge panels  203  and  205  to move towards the sides of the display creating a cavity such that inner sleeve  100  will easily slide down to fill the cavity created in base  300 , thereby creating the closed position of  FIG. 30 . The inventor suggests that every inner sleeve and base combination will have a slight variation of the precise movement required to adequately release the inner sleeve into the base. For example in the structure of candy dispenser of  FIG. 52  a quick uniform jerk of the tabs quite elegantly releases the inner sleeve filled with candy into the base, however, when the inner sleeve is empty, after the tabs a jerked to the right and left the inner sleeve is engaged correctly within the base but will not slide down until it is pushed down, as there is not enough weight in the inner sleeve for self propulsion. By comparison when using the structure as a retail display, of  FIG. 22 , loaded with heavy product, during assembly, it is easier to release one side of the inner sleeve into the base first then the other side. Here it is also important to note that foot-bridge  233  of  FIG. 40  may be made from different material than ledges  235  and  236 . For example if a retail display is particularly heavy the foot-bridge may be made from material suitable to hold the weight. If necessary it may be made from solid wood with a cut in foot slot, while ledges  235  and  236  of  FIG. 40  may be made from plastic corrugated. It is the intent of the inventor, to have the ability to vary the functionality of the ledge system. For example you may increase or decrease the amount of tension or the strength of the ledges by adding or removing compression panels as shown in  FIG. 41 ,  FIG. 42  and  FIG. 43 . For easier deployment of heavier inner sleeves the compression panels of double ledge  200  may be custom trimmed as shown in  FIG. 10  and  FIG. 12 . The ledges may be made shorter if it is desired to have the inner sleeve reside deeper inside the base when in the open position as shown in  FIG. 4 . Also, depending on the duration of storage, and or the humidity of where the structure will be deployed, it may be necessary to have the double ledge structure may be made from different flexible materials such as plastic, plastic corrugated, rubber or other suitable materials. Further, as previously described, the ledge structure may be modified to use only a single ledge as shown in  FIG. 42 . Further the ledge, or double ledge structure may be reversed in how it is folded inside the base (not shown). For example, instead of having compression panels  210 ,  211 ,  212 ,  213  of double ledge  200  reside between ledge panel  203  and base panel  304 . Ledge panel  203  may be adjacent to base panel  304 , with compression panels  210 ,  211 ,  212 ,  213  of double ledge  200  expand into the cavity of base  300  when the inner sleeve is in the UP position. The advantage of doing this is that the ledge structure has the ability to expand further into the base and under the inner sleeve, providing support more evenly under the inner sleeve, as it is no longer constricted by panels  203 . Although this example describes one side of a double sided ledge, the inventor acknowledges that the other side would work the same. When using this ledge structure the tab lock system illustrated in  FIG. 36  and  FIG. 38  is not the preferred method of inserting the sleeve. What is needed are separate multiple tabs per side, or a separate structure to compress the loose panels, one such system is illustrated in  FIG. 57 . 
         [0130]    It is further the intent of the inventor, to build this structure without the use of a separate ledge structure. It is possible to create the lock mechanism and the positions of  FIG. 30 ,  FIG. 31  and  FIG. 32  without a separate single and/or double ledge system as shown in  FIG. 44 ,  FIG. 45  and  FIG. 46 , where the ledge that holds inner sleeve  100  is created by cut and folded flaps  401 ,  402 ,  403 , and  404  of base  400 . Simply by adding cuts  406  and  407  and folds  408  and  409 , flaps  401  and  402  are simply folded inside the base to form the necessary ledge to hold up inner sleeve  100 . The locking catch tabs and catch panels of  FIG. 22  are still applicable and may be used in conjunction to the folding base flap system of  FIG. 46  and  FIG. 47 . It is important to note that it is the intent of the inventor to vary the flaps to meet the need of the structure.  FIG. 47  shows four flaps. This structure may also be successfully accomplished with three, two, or even one flap (not shown). 
         [0131]      FIG. 48  and  FIG. 49  illustrates a sampling table made from two slide and lock structures and a tabletop. This would be useful as it serves both as a table and as a storage device. 
         [0132]      FIG. 50  shows a PDQ display as used by manufacturers and retailers to showcase products. The advantage of this PDQ display is that it has a closed position that is far smaller than the open position. This means that in the closed position, it will ship at a smaller size, and as a result you will be able to fit a lot more displays per pallet. This means less trucks will be required to deliver the same sized order. Less trucks also means less fuel and less CO2 emissions enabling the world to enjoy a cleaner more sustainable environment. Also it is important to note that in this instance there is practically no weight on the internal ledge structure, as its sole purpose would be to keep the AD MESSAGE panel from collapsing back over the product, rather than like in previous examples where the structure supported the weight of the inner sleeve. Also note that the PDQ display structure has a taller back and a shorter front so as to create a slope so that as the product is shopped from the front rows the product in the rear rows will slide down to the front. It is further the intent of the inventor to use this similar structure as a power wing display (not shown), where the AD MESSAGE panel of  FIG. 50  oriented at the top or the bottom of the display and that hooks are placed at the rear of the display to hag the product for display. Much like the PDQ display, shipping efficiency is critical, so a collapsible structure is a desired option, and one that is well suited for the structure of this invention. 
         [0133]    It is further the intent of the inventor not to limit the shape of the structure to a rectangular or square form. The slide and lock structure may be made with mixed materials and in custom shapes, including round, tubular, triangular, and many other even sided or uneven sided structures (not shown). 
         [0134]      FIG. 51  is a further embodiment using the slide locking mechanism for a gift card, flat planar display or the like.  FIG. 51  is a flat slide and lock structure with a top card  500  with bottom catch flap  506  that slides into envelope  501  with catch flap  507 . the ledge  510  is formed by cuts  502 ,  508  and  509 , and fold  503 . Ledge  510  is activated when it is folded  504  inside envelope  501 . It is important to note, that the ledge in this case is small since the card will not require a weight-bearing ledge. 
         [0135]      FIG. 52  shows the Slide and Lock Display as a retractable candy dispenser of  FIG. 25 ,  FIG. 26 ,  FIG. 27  and  FIG. 28  as one that may be used for dispensing Halloween candy. One would purchase the item in a retail store in a collapsed or closed position  FIG. 25 , then for use, the inner Product Tray  100  would be lifted by handle  114  and  113  at the top of the Product Tray, while a foot is inserted into Foot Bridge  316  (not shown) to ensure Base  300  does not rise when the Product Tray  100  is lifted. During use the Mouth  115  is rotated to open position so as to allow easy access to candy. Once the candy giving event is over, Mouth  115  is rotated to a closed position (not shown) and the Product Tray  100  is released back into Base  300  by pulling outwardly on tab  229  an and tab  230  on the opposite side (not shown) ready for storage until it&#39;s next use. 
         [0136]      FIG. 53 . is a plan drawing of a different embodiment of Base  300 . This embodiment includes extended panels  601  and  602  which are modified versions of panels  250  and  251  of  FIG. 12  used to form a modified version of the Inner Shelf Structure as shown in  FIG. 54 . Of particular importance, is that in this modified embodiment, panels  203  and  207  are shortened, and do not reach to the bottom of Base  300 , instead the leading edges  607  and  608  are inserted into slots  604  and  603 , providing enough support so that shelf edges  227  and  228  will support Inner Product Tray  100 . It is important to note that Product Tray  100  in its current embodiment rests on shelf edges  227  and  228 , however the Inner Shelf Structure may also be designed such that the Product Tray may rest on the panels  202  and  208  if desired, instead of resting only on the shelf edges. In this instance it is important to note, that if panels will travel upwards during folding, that slots  603  and  604  are designed in such a way that shelf edges  607  and  608  of  FIG. 54  do not slip out while in folded or closed position. Further, It is the intent of the inventor, to allow variations in the structure such that the deployment of the shelf may be varied to accommodate different needs, for example, should there be a need to hide slots  603  and  604  and or slots  306  and  307  from view a separate insert may be made with the slots in the same position on the Insert, rather than in Base  300 . This would add the expense of a separate Insert, but would minimize or remove altogether any openings that may interfere with artwork on Base  300 .  FIG. 56 ,  FIG. 60  and  FIG. 61  are examples of such Inserts. Product Tray  650  is a modified embodiment of Product Tray  100  where it is assembled with tuck flaps and does not require gluing. See  FIG. 54A  showing the cross-sectional view of the ledge mechanism in  FIG. 54 . 
         [0137]      FIG. 55  is a perspective drawing of two Insert paddles used to help secure Shelf Inserts  803  and  804  inside Base  300  allowing Product Tray  100  to easily be slipped in to Base  300 . 
         [0138]      FIG. 56  shows modified embodiments of Shelf Inserts  251  and  250  of FIG. These Shelf Inserts expand inwardly inside Base  300  allowing Product Tray  100  to be supported not only on surfaces  227  and  228 , but also on surfaces  22 ,  226 ,  223  and  224 . 
         [0139]      FIG. 57  shows Insert Paddle  801  engaged with modified Foot Bridge  205  of  FIG. 12 . Openings  805  and  806  in Foot Bridge  205  accept tabs  803  and  804  respectively, anchoring the Insert paddle as it collapses Shelf Structure  250  between Insert Paddle  801  and the interior of Base  300 . Insert Paddle  801  is locked into position when Tab  807  is pushed over the top edge of Base  300  trapping the inwardly folded flap  311  of Base  300  between the front surface of tab  807  and the rear surface of Insert Paddle  801 . This locked position is repeated on the opposite side of Base  300  with Shelf Structure  251  ad Insert Paddle  802 . Once both Insert Paddles are fully engaged, and the Shelf Structures  250  and  251  are collapsed, then Product Tray  100  may easily be lowered into Base  300 . 
         [0140]      FIG. 58  shows Product Tray  100  loaded with product inside of Base  300 , with Insert Paddles  801  and  802  disengaged from Foot Bridge  205  and being pulled upwards and out of Base  300 , Once Product Tray  100  is lifted past surfaces  223 ,  227  and  224  of Shelf Structure  250  and surfaces  225 ,  228  and  226  of Shelf Structure  251 , then Shelf Structures  250  and  251  will freely expand under Product Tray  100 . 
         [0141]      FIG. 59  is a modified embodiment of Base  300  of  FIG. 13  where Flaps  312 ,  313 ,  314  and  315  are extended and modified to form a Foot Bridge, eliminating the need to have the Foot Bridge as a separate insert. Locking Tab  701  is added to Flap  312 , and Locking Tab  702  is added to Flap  314 . Base Flap  313  and Base Flap  315  are replaced by Bridge Flap  703  and Bridge Flap  704 . Bridge Flap  703  is formed by rolling Flap  703  inwardly so that outer surface of Panel  705  is adjacent to interior of Panel  302 . Bridge Flap  704  is similarly rolled. Once Bridge Flaps  704  and  703  are rolled into position, they are secured with Locking Panels  701  and  702  where tabs  706  and  708 , and Tabs  707  and  709  are inserted into slots  710  and  711  of the rolled Bridge Flaps. Once in position, Panels  712  and corresponding panel  715  (not shown), and edges  713  and  714  form a surface that supports Product Tray  100  during shipping or storage. With this modified embodiment, opening  316  is still used to secure the base with a store associates foot as Product Tray  100  is lifted to engage the Slide and Lock Display System. 
         [0142]      FIG. 60  shows modified embodiment of Product Tray  100  of  FIG. 11  and modified embodiment of Base  300  of  FIG. 13 ,  FIG. 53  and  FIG. 59  where slits  306 ,  307 ,  603  and  604  are eliminated from base  300  and catch Flaps  670  and  671  are added to panels  301  and  303  respectively of  FIG. 13 . Shelf Insert  800  is comprised of panels  802 ,  803 ,  804  and optional panels  801  and  805 . Panels  820  and  821  are rotated inwardly so that tabs  809  and  810  are inserted into openings  807  and  808 . The Shelf ledge is comprised of folded edges  811 ,  812 ,  814  and  815 . When the Product Tray  100  is inserted into Base  300 , Shelf Ledges are collapsed by folding Panels  820  and  821  in such a way that fold  813  is lower than folds  811  and  812  and sandwiched between Panels  822  and  823 , and Fold  816  is lower than folds  814  and  815  and sandwiched between panels  824  and  825 . With Shelf Insert  800  it is the option of the manufacturer to place the Catch Flaps on Product Tray  100  on any two opposing panels corresponding to the Catch Flaps on Base  300 , that when engaged will prevent Product Tray  100  from exiting Base  300 . It is the intent of the inventor to allow more than two opposing Shelf Ledges in this configuration. A manufacturer may choose two, three or four Shelf Ledges and one, two, three or four Catch Flaps. 
         [0143]      FIG. 61  shows a cross section of Shelf Insert  800  in a “closed” position and “open” position where Product Tray  100  is raised past Folds  811  and  814  allowing the Shelf Insert to expand to create a-Shelf Ledge that will support Product tray  100 . It is important to note that if  826  and  827  of  FIG. 60  are added, then the shelf ledge will expand further inward than if these scores are not included. 
         [0144]      FIG. 62  shows how the inclusion of Spring mechanism  828  may be attached or inserted between panels  821  and  804 , and between Panels  820  and  802  (not shown). 
         [0145]      FIG. 63  shows Spring mechanism of  FIG. 62  in expanded or “open” position. It is important to note that the Spring Mechanism may be made from metal, polypropylene, polyethylene, or any other well know suitable material that can provide a flexible Spring Mechanism that will not lose its memory during storage. This addition to the structure may be desired when a display may sit in storage for an extended period of time, where the natural memory of paperboard may not be enough to expand the Shelf Structure as needed. It is Further the intent of the inventor to make the Shelf Insert from materials other than paperboard, such as plastic, corrugated plastic or any other well known materials that would maintain their memory during long periods of storage, or if they are able to offer greater support for heavier products. 
         [0146]      FIG. 64  is a modified embodiment of Shelf Insert  800  of  FIG. 63  where the shelf structure is modified to allow for the automatic deployment of Shelf Ledges  820  and  821  by elastic means as shown in perspective drawing in  FIG. 65   
         [0147]      FIG. 65  is a cut away drawing of Shelf Insert  800  of  FIG. 64  where elastic  853  pulls panel  821  and  820  into an extended position once Product Tray  100  is lifted past Fold  849 . It is important to note that when Panels  821  and  820  are in upright or “closed” position Tabs  810  and  809  must protrude past Openings  842  and  843  allowing Elastic  853  to move freely so that panel  821  can quickly be pulled into an extended or “open” position. 
         [0148]      FIG. 66A  shows Base  300  of  FIG. 53  where Flaps  605  and  606  replace the need for Foot Bridge  205 , and are used to secure Base  300  during the lifting of Product Tray  100 . This structure is desirable when a lower cost option is being considered or if there is a need for Product Tray  100  to be filled to maximum capacity, and the extra space used by the Foot Bridge  205  is not necessary. 
         [0149]      FIG. 67A-C  shows a sequence of steps a Store Associate would go through in setting up a Slide and lock Display System. Store Associate Places their foot into the Foot Bridge  205  (not shown) through slot  316 . Then Product Tray  100  is lifted up until the internal shelf Structure  250  and  251  expands from a “closed” to “open” position. 
         [0150]      FIG. 68  is a Slide and Lock mechanism with a Spring Mechanism designed to assist in the lifting of heavy objects. Even though most retailers have a limit of 40 lbs for displays that require lifting, the inventor contemplates the need to have a display that may be significantly heavier and will require additional assistance in lifting. 
         [0151]      FIG. 69  is a cut away drawing of a Jack in the Box premium that uses elastic  853  to propel Product Tray  100  into an “open” position from a “closed” position 
         [0152]      FIG. 70  is perspective drawings of the Slide and Lock Display System that takes on different shapes. The inventor contemplates that as long as the structure is able to have Catch Flaps on Product Tray  100  and Catch Flaps on Base  300  that engage once Product Tray  100  moves past the “closed” Shelf Structure and the expandable Shelf Structure resides between Product Tray  100  and Base  300  during shipping or storage, then the structure can take on many shapes.
