Pavement structure with self-erasable and reusable writing and drawing surface and method for manufacturing same

The present invention is directed to a packaging structure in which self-erasing, reusable writing and drawing surfaces are combined. In particular, the present invention relates to a pavement structure and a method of manufacturing a self-erasable, reusable writing and drawing surface combined, commonly known as a "magic slate," on at least one of the outer surfaces of the pavement structure.

Applicable to writing pads, slams, blocks and books, sketching blocks, drawing books, etc., Permanent handwriting and painting surfaces were known many years ago that could allow letters, pictures or other content on the surface to be erased or disappeared instantaneously without the use of rubber or other erasing means. In addition, several attempts have been made to improve such writing and drawing devices. For example, US Pat. No. 1,455,579 to Evans is composed of a colored base coated or impregnated with a plastic substance or vehicle, or a handwriting or drawing composed of the plastic substance or vehicle. Disclosed is a writing and drawing surface composed of cotton and materials such as transparent or translucent tissue or other paper, silk, skin and the like. The plastic material or medium and the writing and drawing surface are suitably impregnated, coated or treated with grease or oil.

Typically, for writing and drawing devices, sheets of fabric or the like are arranged on a dark-colored slightly adhesive bottom layer composed of wax matehal, and turnover. Pressing the water sheet against the wax bottom layer causes the pressurized portion to stick to the bottom layer so that letters or pictures appear on the bottom layer, resulting in letters and pictures. To erase text and pictures, the press fabric sheet may be lifted from the bottom layer.

Continue to lift and press the top sheet over a certain number of times against the waxed bttom layer, usually breaking the top sheet, which is usually thinner and more fragile. Attempts to alleviate this problem are disclosed in US Pat. No. 1,512,827 to Deutsch, which protrudes across a writing surface between an adhesive bottom layer and an upper layer overlying it. An obliteration device is described which has the form of a strip, a string, a wire and at the same time separates the adhesive portion from the adhesive portion. Another improvement attempt is disclosed in US Pat. No. 1,543,430 to Fischer, which maintains the upper and lower members flat and smooth to prevent the members from being wrinkled or damaged. An apparatus for fixing together is described. US Pat. No. 1,555,642 discloses a third protective sheet or layer composed of a relatively strong material that further protects the second sheet and the wax coat. US 1,568,548 to Edelson protects an overlaid paper or sheet by covering the overlaid paper or sheet with a thin transparent sheet of cellulose material. Finally, US Patent No. 3,321,849 to Langbart discloses a "magic slate" similar to those described above, except that it discloses a slider that extends the width of the magic slate and extends between the translucent material sheet and the adhesive layer. Is described. As the slider moves from one end of the slate to the other, the translucent material sheet and adhesive layer are separated to remove any letters or pictures.

The use of packaging premiums as a means of sales promotion is widespread. However, in the case of packaged foods such as cereals, the gifts used are usually in the form of "drop-ins". The complete certainty that each package will contain gifts such as "interior" is certainly less than 100%. In addition, the increase in promotional costs associated with handling "decorative" gifts has risen to the point where economic benefits are low. Therefore, the necessity of devising a new promotion scheme has been continuously increased, and the present invention provides a new packaging structure and a method of manufacturing the same, which provide a promotion scheme which eliminates the necessity of using promotional "embedded" gifts.

However, none of the foregoing patents describes reusable writing and drawing surfaces used as devices that combine packaging mediums, such as folding cartons, to facilitate product sales.

It is therefore an object of the present invention to produce reusable writing and drawing surfaces on packaging media that the buyer can see directly.

Another object of the present invention is to provide a reusable handwriting and drawing surface that is not in a "built-in" form and has increased in size and value.

It is yet another object of the present invention to provide a reusable writing and drawing surface that allows a consumer to use the writing and drawing surface on the container without compromising the carrying and / or protective functions of the container.

It is a further object of the present invention to provide a method for combining writing and drawing surfaces with packaging media such as collapsible cartons or other containers having at least one relatively rigid surface.

Other objects of the present invention will become more apparent from the following detailed description.

The present invention relates to a printed colored background, pressure sensitive adhesive media, which is added to a colored printed background and adapted to receive indentations from a drawing or writing implement, covered on an adhesive medium. Ovlay film, a second contact for attaching the entire periphery of the top film except the top of the top film to form a non-destructive bond, retaining the top film in place during use A self-removable, reusable writing and drawing surface consisting of a destructive adhesive applied on top of the top cover film and a separating means for separating the top cover film from the packaging surface for the purpose of at least one of the outer surfaces of the packaging structure. It relates to a pavement structure coupled to. The present invention also provides a method of printing a cardboard web with appropriate background colors and graphics, applying a pressure sensitive adhesive to the same area that overlaps the background color, and providing a non-destructive bond. Applying the top cover film to the side containing the pressure sensitive adhesive as a second adhesive to tritize the entire periphery of the cover film except the top of the top cover film to form a pressurized adhesive under pressure; A method for manufacturing a packaging structure consisting of applying a destructive adhesive on top of a top cover film to hold the film in place and folding the cardboard into a carton to fit the application.

The present invention relates to the coupling of a "magic slate" shaped drawing surface to a packaging medium for use as a sales promotion device. The present invention utilizes a single overhy film onstruction that differs from the most conventional "dual overlay system" known as "magic slate," and by means of a standard window applying machine. It may also be prepared.

In the present invention, a top plate is formed to form a colored printed base, a pressure sensitive adhesive medium added to the colored printed base and adapted to receive indentations from a drawing or writing instrument, a top film overlying the adhesive medium, and a non-destructive adhesive. A second adhesive for attaching the entire periphery of the top film except the top of the film to the pressure sensitive adhesive, a destructive adhesive applied to the top of the top film by holding the top film in place during use, and the top cover A pavement structure is produced in which a self-erasable, reusable writing and drawing surface composed of beak means for separating the film from the pavement surface is combined on at least one of the outer surfaces of the pavement structure.

In accordance with the invention an adhesive material such as wax or similar adhesive materials which flow in the molten or plastic state and which adhere to the ink coating are applied directly above the ground color. The topsheet or film is attached at its periphery just above the plastic flow adhesive coating.

The top film should have sufficient opacity to allow prephnting. The opacity should be such that it reflects light except when the film is in close contact with the plash adhesive. The top film must also be durable enough to resist scuffing, sterching and wrinkling. Typical "magic slates" are designed based on two top cover films. The durable and transparent outer film serves to resist distortion, while the flexible and translucent inner film serves to accommodate the drawing surface.

The single top cover film of the present invention is firmly attached to the carton to resist damage during handling, packaging and transport operations. However, bond is such that the film can be separated from the outer surface of the container without damaging the container or the film. This type of adhesion between the film and the container occurs due to the inherent properties of the adhesive. A second adhesive is applied to the periphery of the drawing board except for the top, which causes a non-destructive type bond. At the top of the top film is applied a destnlctive adhesive necessary to hold the top film in place during use. This non-destructive adhesive provides a complete separation of the film from the container except the top portion, This enables the continued use of the write and erase features of the present invention.

The writing surface provided by the present invention is only applicable to pavement structures having at least one relatively flat and rigid surface. A typical example of such a suitable container is a paper-board carton such as used to dispense cereal products. The dark colors applied to one side of the carton serve as a background color. Various colors and printed patterns can be planned for paint designs.

The present invention also provides a method for producing a packaging structure in which self-erasable and reusable writing and drawing surfaces are combined on at least one of the outer surfaces of the packaging structure, the method comprising the steps of: printing a cardboard web with appropriate shapes and background colors; Applying a pressure sensitive adhesive to the same area overlapping the ground color with the second adhesive to press the entire periphery of the top film except for the top of the top film to form a non-destructive adhesive. Applying a top cover film to the side containing the force sensitive adhesive, applying a destructive adhesive on top of the top cover film to hold the top film in place during use, and cartoning the carton as appropriate It provides a method of manufacturing a packaging structure consisting of a folding step.

The writing surface on the carton is manufactured in a conventional carton production facility. First, the cardboard web is printed with the appropriate carton figures. During printing of the figures, the background color is applied to the web in the appropriate area of the carton. The typical shape of the ground color is a rectangle centered on the back panel of the carton. However, the background color can be in various shapes and can also be applied to any area on the carton.

A pressure sensitive adhesive or plastic adhesive is applied to the periphery of the background color and superimposed on the background color. These adhesives can be applied to the web in the form of a coating, dried to a sufficiently rigid coating so as not to cause blocking at a reverse presented roll, and have the property of adhering the top film to the outer surface of the container under pressure. have.

The pressure sensitive adhesive is applied to the same area as the ground color just above the ground color. Suitable adhesives are mixtures of parafhn and microcrystaline waxes combined to flow slightly under the pressure of a writing stylus. The apparatus for applying the plastic adhesive consists of a transfer roll which is rotated and measured in a bath of moltenwax. The second applicator roll consists of rubber pads molded into the shape of the paint color and attached to a steel base proximate both the delivery roll and the carton. The wax is sequentially delivered from the melting bath to the delivery rolls, the applicator rolls and the carton. The amount of wax transferred from the melting bath to the carton is determined by the (smooth or corroded) surface preparation of the delivery roll, the distance between the rolls, the distance from the rolls to the carton, and the viscosity of the wax mixture. Is determined.

The smoothness of the wax coating and its penetration into the carton are controlled by the thermal conditioning of the carton prior to applying the top cover film using radiant heaters. In the present invention, any other base materials and additives other than waxes showing suitable properties may serve as plastic adhesives.

Generally, the top cover film is applied in a separate operation to the waxed web. The film applicator first peels off the top cover film from the roll, cuts it to a predetermined length, and places it on the plasticized film. The film is preferably applied to the coating while the coating is molten or tacky. The plastic adhesive coating temporarily adheres the top cover film to the carton and prevents the use of the picture tube until the top cover film is lifted up. In the same operation, the pressure controlled rolls bond together the cartonol with the pressure sensitive region of the film. The top cover film has an area equal to the area of the pressure sealing media or a slightly narrower area to ensure that the outer edges of the film are secured to the carton.

The top cover film is applied to the side containing the pressure sensitive adhesive by a second adhesive necessary for attaching the peripheral portion of the film to the pressure sensitive adhesive. The second adhesive is applied to the periphery of the top cover film except the top before contacting the pressure sensitive adhesive. At the top of the film is applied a destructive adhesive that permanently retains the upper portion in contact with the pressure sensitive adhesive to enable the continued use of the writing and erasing features of the present invention. The pressure sensitive adhesive applied to the carton and the adhesive applied to the periphery of the film are allowed to adhere only to themselves.

The finished package is filled, transported and sold in the usual way. The consumer utilizes paint by purchasing a packaged product, holding the edge of the top cover film and lifting the film freely from the outer surface of the carton. The lift tab feature, coupled to the carton design, aids consumers in use by providing access to the unfixed edges of the film. One edge of the film remains firmly attached to the container. Using a stylus, such as a nail, an end of a pen, a spoon, a device wrapped in a container, or other blunt tools, the consumer presses the top cover sheet in a narrow line to contact the sheet with the plastic adhesive. The adhesive is deformed and flows into surface aberrations that previously reflected scattered light to make the surface appear translucent. The light irradiated on the areas of the top cover film that is in contact with the plastic adhesive is transmitted through the film into the adhesive rather than being reflected. These areas look dark, allowing writing and drawing. Those marked on the writing surface are separated by holding the edge of the top cover film again and removing the film from the adhesive to remove all contact surfaces.
