Containers are described that allow a consumer to see inside the container and to more easily access the products. One form of the container includes a base member with a lid defining a window. A flexible laminate with a peelable flap portion is attached to the lid to provide access to the products inside. The flexible laminate includes a first film layer laminated to a second film layer. The first film layer includes a first cut line defining a peelable flap portion and the second film layer includes a second cut line offset from the first cut line that defines an opening into the container. First and second reclose surfaces defined between the cut lines on the corresponding film layers include pressure-sensitive adhesive to allow the container to be re-sealed via movement of the peelable flap portion back into engagement with the flexible laminate remaining with the container.

1. A container for storing products comprising: a base member comprising a base, four sidewalls, and a lid that define a storage cavity, wherein the storage cavity is configured to hold products therein, and wherein the lid defines a window; anda transparent flexible laminate configured to be attach
1. A container for storing products comprising: a base member comprising a base, four sidewalls, and a lid that define a storage cavity, wherein the storage cavity is configured to hold products therein, and wherein the lid defines a window; anda transparent flexible laminate configured to be attached to the lid of the base member so as to cover the window and, in cooperation with the base, four sidewalls, and lid, enclose and maintain the products within the container,wherein the flexible laminate comprises: a first film layer, anda second film layer laminated to the first film layer, wherein the first film layer comprises a first cut line defining a peelable flap portion and the second film layer comprises a second cut line offset from the first cut line and defining an opening providing access into the storage cavity,wherein the first film layer forms a first reclose surface between the first and second cut lines, and the second film layer forms a second reclose surface between the first and second cut lines,wherein at least one of the first or second reclose surfaces includes pressure-sensitive adhesive to allow the peelable flap portion to be re-sealed to a remainder of the flexible laminate so as to reclose the opening when the first reclose surface is brought into engagement with the second reclose surface via movement of the peelable flap portion; andwherein the peelable flap portion is smaller than the window. 2. The container of claim 1, wherein the base member comprises a folded carton made of paperboard. 3. The container of claim 1, wherein the first film layer of the flexible laminate comprises polyethylene terapthalate (PET) and the second film layer of the flexible laminate comprises oriented polypropylene (OPP). 4. The container of claim 1, wherein the flexible laminate is attached to an outer surface of the lid of the base member. 5. The container of claim 1, wherein the flexible laminate is attached to an inner surface of the lid of the base member. 6. The container of claim 5, wherein the lid of the base member defines an extension overlying a pull tab of the peelable flap portion, wherein the extension serves as a tamper evident feature. 7. The container of claim 6, wherein the extension comprises at least one line of weakness, wherein each line of weakness is configured to be torn by a user to gain access to the pull tab. 8. The container of claim 1, wherein one of an outer surface or an inner surface of the lid of the base member is coated with low density polyethylene (LDPE), and wherein the flexible laminate is heat sealed to a respective one of the outer surface or the inner surface. 9. The container of claim 1, wherein the flexible laminate is glued to one of an outer surface or an inner surface of the lid of the base member. 10. The container of claim 1, wherein the lid of the base member has a width and a length corresponding to a width and a length of the container, and wherein the window defined by the lid has a width and a length that are smaller than the width and the length of the lid, respectively. 11. The container of claim 1, wherein the container is configured for holding pet products. 12. The container of claim 1, wherein the first and second film layers are laminated to each other via pattern-applied permanent adhesive and pressure-sensitive adhesive. 13. The container of claim 1, wherein the first cut line comprises a first side portion, a second side portion, and an intermediate portion extending therebetween, and wherein the first and second side portions include free ends that are spaced apart. 14. The container of claim 1, wherein the second cut line forms a closed shape. 15. The container of claim 1, wherein the first cut line defines a pull tab portion. 16. A method of making a container for storing products, the method comprising: forming a base member comprising a base, four sidewalls, and a lid that define a storage cavity, wherein the storage cavity is configured to hold products therein;defining a window in the lid of the base member;forming a flexible laminate by: creating a first cut line in a first transparent film layer, wherein the first cut line defines a peelable flap portion which is smaller than the window,creating a second cut line in a second transparent film layer, wherein the second cut line defines an opening providing access into the storage cavity, andlaminating the first film layer to the second film layer; andattaching the flexible laminate to the lid of the base member so as to cover the window and, in cooperation with the base, four sidewalls, and lid, enclose and maintain the products within the container,wherein the first film layer forms a first reclose surface between the first and second cut lines, and the second film layer forms a second reclose surface between the first and second cut lines, andwherein at least one of the first or second reclose surfaces includes pressure-sensitive adhesive to allow the peelable flap portion to be re-sealed to a remainder of the flexible laminate so as to reclose the opening when the first reclose surface is brought into engagement with the second reclose surface via movement of the peelable flap portion. 17. The method of claim 16, wherein the first cut line defines a pull tab portion and wherein the flexible laminate is attached to an inner surface of the lid of the base member. 18. The method of claim 17 further comprising defining an extension of the lid of the base member overlying the pull tab of the peelable flap portion, wherein the extension serves as a tamper evident feature. 19. The method of claim 18 further comprising defining at least one line of weakness in the extension, wherein each line of weakness is configured to be torn by a user to gain access to the pull tab. 20. The container of claim 10, wherein the peelable flap portion has a width or a length that are smaller than the width or the length of the window, respectively.
