[Procedural amendment] [Submission date] October 18, 1999 (1999.10.18) [Content of amendment] Description Technical field of three-dimensional insert structure The present invention relates to packaging technology, and in particular, automated packaging equipment. The present invention relates to a three-dimensional insert structure supplied in a continuous web of inserts , which can be easily handled with the insert . BACKGROUND OF THE INVENTION In particular, a packaging device adapted to process inserts or strips fed into a web having a continuous perforation is disclosed, for example, in US Pat. No. 5,079,901 to the applicant. I have. The apparatus and system described in that patent receives a continuous web of perforated strips and provides a cutting edge strip between a pair of supply rolls and a pair of break rolls for a desired time. At, the cutting edge piece is separated from the continuous web by applying a breaking tension to the transverse perforation separating the cutting edge piece from the next piece. The detached piece is moved at a desired time to an insertion point such as a moving container based on a signal provided in a time circuit. Another insert processing device is disclosed in U.S. Pat. No. 5,549,233. This patent describes an insert processing device that smashes three-dimensional pieces using a pair of laterally spaced rolls. This configuration allows the three-dimensional form of the insert to "pass" the processing equipment between the set of spaced rolls. However, these devices are problematic because the protruding strip insert requires a flat area to be used to drive the strip to break or protrude into containers. DE 2730133A1 discloses a bag for liquid or powdered products made of two foil rolls and a two-part insert attached thereto . The patent shows that such a construction solves the problem of a bag containing a liquid or powder breaking or breaking open when subjected to high mechanical stress . Structure of the bag and insert is stated that the child overcome such structures. One attempt to overcome the problems of this current technology has been to provide an insert that uses a piece of hard cardstock along with a three-dimensional object. More added stiffness to the card stock gives desired hardness to the insert, or gave the use of harder film. However, any conventional technologies, storage and three-dimensional content of the insert is unable to be resolved or overcome the problem that is moved laterally around the card stock during processing, is used to fracture treatment Interfere with the roller. This is particularly problematic when high pushes are required for the inserts, requiring frequent shutdown of the processing line. Another approach is to use adhesive on the cardstock and / or cardstock to secure it to the desired location on the object. Although this approach can solve the problem of lateral movement of the three-dimensional object, it significantly increases the cost of manufacturing the insert. Furthermore, prone to problems in the correct alignment of the object to a region painted adhesive cardstock. Also, the adhesive remaining on the object is not desirable for the end user. Yet another approach is referred to as a "skin pack", in which a plastic film is attached to a perforated paper backing material, through which a vacuum is applied to match the film to what is being packaged. Although this method can also be characterized as solving the problem of lateral movement, perforated paper backings are not suitable for the permeability requirements of most food-friendly inserts. DISCLOSURE OF THE INVENTION It is a major object of the present invention to overcome the shortcomings of the prior art. It is a further object of the present invention to provide a three-dimensional insert that can be easily manufactured at an acceptable cost and can be easily processed with a one-piece processing device. The present invention contemplates these and other objects by providing card stock or paperboard (hereinafter referred to as card stock) defined by first and second opposing ends and first and second opposing sides. ) Provided by a three-dimensional insert having a piece. A heat sealable, olefin-based coating or film is applied to the top of the cardstock. The coating material is adhered to the coating and seals between the coating material and the surface of the cardstock. This arrangement provides a relatively solid surface, which is easily captured by the processing equipment. In this way, prizes and other three-dimensional objects are retained inside the coating without moving to the peripheral sides used to process the insert. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a first insert fed into a continuous web of inserts, followed by the insert. FIG. 2 shows a piece of cardstock having a heat-sealable coating. FIG. 3 is a cross-sectional view of the insert of FIG. 1 taken along line 3-3 of FIG. The present invention relates to an insert used for packaging applications. This insert is particularly suitable for processing in automated processing equipment, for example as disclosed in US Pat. No. 5,549,233, the contents of which are incorporated herein by reference. Such devices are adapted to engage the peripheral side edges of the insert while positioning the three-dimensional object in the central part of the insert path between sets of rolls, and to apply various types of three-dimensional objects. Processing. By way of example, the three-dimensional object is a prize, a prize, or a packaging component or the like, which is inserted into a container of cereal, such as a box, bag, pocket or the like. Alternatively, the insert is a package of seasonings or seasonings that is placed in the container while physically separating it from the rest of the contents of the container. FIG. 1 is a perspective view showing first and second inserts or pieces 10, 12 fed into a continuous insert web or stream. In a preferred embodiment, each of the inserts comprises a three-dimensional piece or object 10p, 12p, which is ultimately placed in containers. By way of example, the object is a prize supplied in a cereal box, a food package or other suitable container. Alternatively, the small pieces 10p, 12p are small packages used for food packaging or similar applications. The inserts 10,12 are preferably provided in a continuous web format with perforations and are separated from each other by transversely extending perforations 14 in the web connecting the inserts 10,12. The rest of the insert in the web are connected to each other physicians in the same way. FIG. 2 shows a small flat piece of material 20 that can withstand the processing of relatively flat card stock, paper board, or automated processing equipment. In this way, the pieces of cardstock provide structural support for the insert. Small pieces of card stock are defined by a pair of opposing ends 20e, opposing sides 20s, and a top surface. FIG. 2 also shows a cardstock strip 20 having a heat sealable coating 22 applied over the top surface of the cardstock. Coating 22 is preferably an olefin-based material or a material with suitable heat sealing properties. Alternatively, a pair of strip-like coatings or adhesives (not shown) can be applied to the peripheral edges of the card stock 20, preferably close to the sides 20s. In this embodiment, the surface of the card 20 can be covered with a strip of a heat-sealable olefin-based material, which extends between the ends 20e in the longitudinal direction of the strip 20. It should be noted that the coating may be applied to the top surface of the cardstock strip in other forms, such as in a spaced area. The small pieces of cardstock 20 and the objects 10p with the heat sealable coating are covered with a plastic covering, such as a covering 26. For example, like a sterile packaging insert , the coating material can also surround the object and the cardstock and provide a barrier to the outside. Preferably, the ends 26e of the coating material are heat sealed together to provide a lateral band, which is perforated or otherwise weakened near the end 20e of the cardstock. You. The side 26s of the coating material is also preferably heat sealed or glued or joined to the side of the top surface of the card stock 20 to completely enclose the three-dimensional object. Another method of joining the coating material to the side of the top surface of the cardstock 20 is to apply pressure to the coating material and coating using rollers and seal them. In any case, a seal is provided between the coating on the surface of the cardstock and the heat-sealable coating near the side edges of the cardstock. Preferably, the coating material is made of the same material as the coating material, for example, an olefin-based material. However, the coating material is of a different material as long as it exhibits adhesive properties such that when heat and / or pressure is applied to the side edges of the cardstock, it is easily retained on the top surface of the cardstock. May be made with Therefore, three-dimensional objects such as promotional pieces or packaging are prohibited from moving laterally or from moving toward the side edges around the insert, increasing the distance from the processing equipment. You can keep it. Furthermore, the device makes the side surfaces, which are the areas of the inserts processed by the processing device, relatively flat and even. As described in U.S. Pat. No. 5,549,233, the web of insert is positioned on a processing device that joins the sides of the insert . At this point, a pair of spaced-apart supply rolls join the side edges of the leading edge insert in the web and allow the strip to flow to a predetermined location downstream, but preferably the leading edge strip is The separation is performed while the perforated line is located between the pair of supply rolls and the rupture rolls while the leading-edge piece is engaged with the pair of rupture rolls separated from each other. At the desired time, the breaking roll rotates at an associated angular velocity faster than the feed roll, imparting breaking tension to the perforation between the leading piece and the next piece, and cutting the leading piece. Is separated from the rest of the web and the pieces are placed in containers. In this way, the three-dimensional insert described above is easily placed in the container. Thus, a three-dimensional insert that meets the foregoing objects has been described. This insert has an improved structure as well as a processing capacity and is integrated.
