5 CONSTRUCTIONAL ARRANGEMENT WITH TWIST-ON CLOSURE INTEGRATED INTO THE PACKAGING Utility model field

[001] This utility model relates to the field of constructive closure arrangements applicable to packaging, encompassing solutions designed to allow the resealable closure and reopening of packaging after initial opening. The constructive arrangement is applicable, among others, to the food, pharmaceutical, cosmetic and electronic sectors, in packaging that demands ease of use and maintenance of content containment. Fundamentals of the utility model

[002] In the state of the art, several closure solutions for packaging are known, such as seals, adhesives, removable closures and plastic zippers. These solutions have limitations related to reuse after initial opening, difficulty of handling or incompatibility with certain packaging materials, especially in flexible packaging.

[003] The proposed constructive arrangement seeks to overcome the limitations observed in the state of the art by integrating at least one flexible element, preferably two, arranged on opposite faces of the packaging envelope, allowing closure and reopening by manual twisting after the initial opening, without the need for additional external elements, being applicable to different types of packaging and materials.

[0012] Figure 9 illustrates the constructive arrangement applied to flexible packaging intended for the containment of powdered or granulated products, showing flexible elements integrated into the packaging shell. Description of the utility model

[0013] The constructive arrangement of twist closure integrated into the packaging comprises at least one flexible element, integrated into the packaging envelope, intended to allow the packaging to be closed and reusably reopened after initial opening.

[0014] The flexible element is preferably made of metallic wire, coated or not with a polymeric, biodegradable or functionally equivalent material, and is integrated into the packaging envelope by a process of heat bonding, thermal welding or other means compatible with the packaging material.

[0015] The constructive arrangement can be applied to different types of flexible packaging intended for the packaging of food or various products, regardless of the packaging material, provided that it is compatible with the integration process of the flexible element.

[0016] The integration of the flexible element into the packaging preferably occurs during the packaging manufacturing process, so that the flexible element becomes structurally part of the final packaging.

[0017] After the initial opening, the user can close the packaging by manually twisting the flexible element, and the opening and closing procedure can be repeated as needed.

[0018] The construction arrangement may employ recyclable or biodegradable materials, depending on the desired application and the requirements of the packaged product.

[0019] The constructive arrangement is applicable to different industrial sectors, including food, pharmaceutical and cosmetic, and can be used in flexible packaging that requires reusable closure after initial opening. Petition 870260057693, dated 06 / 13 / 2026, page 5 / 9 / 5

[0020] Because it is integrated into the packaging, the design reduces the need for additional external closure elements, helping to maintain the containment of the contents.

[0021] The constructive arrangement is compatible with industrial packaging manufacturing processes and can be incorporated into existing production lines without significant structural changes.

[0022] The construction layout can be sized and adapted according to the characteristics of the product to be packaged and the packaging material.

[0023] The constructive arrangement can be applied to packaging intended for different storage conditions, provided that the materials used are compatible with the thermal conditions involved.

[0024] The twist-lock closure design integrated into the packaging constitutes a technical solution designed to allow for the simple and functional resealable closure of packaging. Examples of implementations of the utility model

[0025] One way of implementing the constructive arrangement involves integrating a flexible element made of coated metal wire into the packaging casing, allowing it to be twisted closed after initial opening.

[0026] The constructive arrangement can be applied to flexible packaging used for dry products, in which the reusable closure contributes to maintaining the containment of the contents.

[0027] Another embodiment involves the application of the constructive arrangement in flexible packaging intended for bakery products, allowing for closure after each use.

[0028] The construction arrangement may vary in terms of the positioning, quantity and orientation of the flexible elements, according to the type of packaging and the manufacturing process adopted. Petition 870260057693, dated 06 / 13 / 2026, page 6 / 9 / 5

[0029] Thus, the constructive arrangement of twist closure integrated into the packaging presents itself as a technical solution applicable to different types of flexible packaging, allowing reusable closure after initial opening. Petition 870260057693, dated 06 / 13 / 2026, page 7 / 9
