Petition 870250008270, dated 01 / 31 / 2025, page 6 / 22 2 / 5 constructive comprises interlocking parts in plastic material (3) and (4), which receive at the ends PVC plastic sheets (1) applied in a single way with the (F) and the adhesive film.” Note that the document presented mentions in the composition of the sliding latch, the replacement of metal terminals by PVC plastic sheets, however the durability of its functionality is short and poor application may occur in the manufacturing process, as well as the addition of this item which should be applied with some caution, losing time for exact alignment, not to mention that it must be applied to both ends of the sliding latch. ADVANTAGES OF THE INVENTION

[004] The following can be understood as advantages of the invention: • Simple construction and reduced number of components; • Electronically cut edges on the self-adhesive paper for easy removal; • Electronic cutting following the guidelines on the paper; • Instructions on the self-adhesive paper for cutting the feed bag correctly; • Use super glue to join the ends of the sliding fastener and eliminate any moving parts; • It is impossible for the ends of the closures to accidentally fall inside the packaging and be ingested by animals. • Greater safety and durability for the feed packaged in the container. OF THE INVENTION

[005] The present patent application aims to reduce moving components, electronically cut the self-adhesive paper to cut the feed bag properly and with reduced pressure, electronically cut the edge for easy detachment, and use a superglue (mixture of polyurethane solvent with polystyrene) to eliminate moving terminals and join the ends of the sliding closure. GENERAL DESCRIPTION OF THE INVENTION Petition 870250008270, dated 01 / 31 / 2025, page 7 / 22 3 / 5

[006] The patent application for invention comprises a sliding closure welded by a high-frequency machine onto a rectangular adhesive label, which includes an indicative print for proper cutting, previously electronically cut, to reduce cutting resistance. The perimeter edges are also pre-cut for easy removal of the label from the paper base. Once the label is adhered to the animal feed bag, the bag is cut with a cutting tool, the pre-cut adhesive reducing cutting resistance. Furthermore, a superglue, a solvent compound of polyurethane and polystyrene, is applied to the ends of said sliding closure, acting as terminals, resulting in the elimination of traditional movable terminals, such as metal terminals, plastic terminals, and PVC sheets.

DETAILED TECHNICAL DESCRIPTION

[008] The FEED PACKAGING CLOSURE WITH PREVIOUSLY SECTIONED ELECTRONIC CUT, WITH ENDS APPLIED BY GLUE AND PROCESS OF APPLYING THE CLOSURE TO THE PACKAGING, is a packaging closure (1) with a rectangular adhesive base (1'), electronic cut or label, and non-metallic sliding closure (2) welded by a high-frequency machine, indicated in (S) next to laminated strips (3) on the rectangular adhesive base (1'), electronic cut or label, which is previously sectioned (L1) for application on the surface (S1) of the feed bag (B) or similar, on which the rectangular adhesive base (1') is positioned; whereby said sliding closure (2) is applied to superglue (C), composed of polyurethane solvent and polystyrene, at the ends (E and E'), the materials used in gluing and in the sliding closure (2) being the same.

[009] More specifically, the packaging closure (1) with rectangular adhesive base (1'), electronic cut or pre-sectioned label (L1) on the indicative line (L), combines the sliding closure (2) to be applied to the surface (S1) of the feed bag (B) so that, when the cut is made, it will only be made on the feed bag (B), given that the electronic cut (1') is already sectioned (L1), which reduces the cutting pressure and makes this operation more efficient; with regard to the application of the laminated strips (3), it is done by a mold, so that the high-frequency machine performs the Petition 870250008270, dated 01 / 31 / 2025, p. 9 / 22 5 / 5 welding of the laminated strips (3) onto the rectangular adhesive base (1'); superglue (C) is applied to the sliding fastener (2) before going to the high-frequency machine at the ends (E and E'), replacing traditional moving terminals such as metal, plastic and PVC sheets, which eliminates the risk of entering the feed bag and accidental ingestion, causing harm to the animal's health.

[010] For applying the packaging closure (1), the sliding closure (2) is opened by removing the rectangular adhesive base (1') from the protective paper (P) through the perimeter edges (BO) cut out for application by adhesion to the surface of the feed bag (B) or similar; once this is done, with the label (1') already glued to the surface of the feed bag (B), with the sliding closure (2) open, the pre-cut sectioning in (L1), in the electronic cut (1'), or adhesive base, is exposed, and only the surface of the feed bag (B) should then be cut; closing the sliding closure (2) ensures the safety and preservation of the product housed inside the aforementioned feed packaging.

[011] That is, according to the invention, the aforementioned pre-sectioning (L1) is provided in the rectangular adhesive base (1'), electronic cutout or label, in its center, which coincides in position with the indicative line (L) on the label (1'), the latter being as a guide for cutting the surface of the feed bag (B), with a cutting object (OC), after applying the object of the invention to said surface of the feed bag (B); in this way, the result is more effective in precision, given that the adhesive layer marked with the line (L) does not need to be cut, only the cut to be made on the feed bag (B); additionally, there is better use of closure and preservation of the food inside the feed bag (B), in addition to preventing the packaged product from losing its properties.

[012] Therefore, the present patent application aims to reduce moving components, as well as propose a cutting action only on the feed bag (B), applied to the line (L) indicating the label (1'), in a more practical and efficient way, while the use of a superglue (mixture of Polyurethane solvent with Polystyrene) eliminates the need for moving terminals and joining the ends of the sliding closure.
