Description
- This invention relates to releasable packaging closures.
- Product packaging is used for transporting, storing and displaying a multitude of materials including foodstuffs and bulk materials, for example. It is often a requirement of these packages that they be opened and reclosably secured repeatedly without the use of a multiple fastening devices.
- Closing and securing product packaging often entails the application of adhesive tape. With cardboard containers, the upper flaps are folded into overlapping or adjacent contact and adhesive tape is applied to secure the flaps together. When the container is to be opened, the adhesive tape is generally either cut or stripped off, which necessarily limits the practical reuse of the container. Reclosure of the container may not be possible if the flaps were damaged from stripping off the adhesive tape. Alternatively, if the flaps remain undamaged, the adhesive tape must be reapplied to effect closure of the package.
- According to one aspect of the invention, a fastener product is provided including a first base having an inner face and an outer face opposite the inner face, the first base comprising a first array of fastening elements on a first portion of the inner face and an adhesive coating on a second portion of the inner face, a second base having an inner face and an outer face opposite the inner face, the second base comprising a second array of fastening elements releasably engageable with the array of first fastening elements of the first base on the outer face and an adhesive coating on the inner face of the second base, the first portion of the first base at least partially overlaps the second base, such that the fastening elements of the first base engage the fastening elements of the second base, and wherein the first base is positioned adjacent to the second base to enable the first array of fastening elements to engage the second array of fastening elements.
- In one embodiment, one of the first or second arrays of fastening elements are loop-engageable fastening elements and the other are hook-engageable fastening elements. In some cases, the loop-engageable fastening elements are integrally molded with the first base. In some presently preferred embodiments, the adhesive coating of the first base and the adhesive coating of the second base lie in substantially the same plane.
