[0024] Disclosed herein are implementations of integrated closures and containers. The implementations shown are illustrative and other implementations may include grips or protrusions for aiding in opening the integrated closure which are within the scope of the specification and claims described herein.

[0025] FIG. 1 is a view of an integrated closure and container 100 in a closed position in accordance with some implementations. The integrated closure and container 100 includes a container 110 and an integrated closure 120. The container 110 has a body 112 and a shoulder 114. The integrated closure 120 includes a base 130, a sidewall 140, and a lid 150. The height of the sidewall 140 is dimensioned to accommodate at least a neck (shown in FIG. 6 and FIG. 7) of the container 110. As described and shown in FIG. 6, FIG. 7, and FIG. 8, the width of the shoulder 114 of the container 110 is dimensioned to be bigger than the width of the integrated closure 120 as a tamper proof mechanism.

[0026] FIG. 2 is a top view and FIG. 3A is a perspective view of the integrated closure 120 of FIG. 1 in accordance with some implementations. The integrated closure 120 has a base 130, a lid 150, a hinge 200, and a tamper indication or evident membrane 210. The lid 150 includes a lid body 154 connected to a lid sidewall 156, which in turn is connected to a tab 158. The lid 150 is connected to the base 130 via the hinge 200 and the tamper indication membrane 210. The hinge 200 is a flexible membrane which allows the lid 150 move between an open position and a closed position as shown and described in FIG. 3B. The hinge 200 is located at an edge between the lid 150 and the base 130 such that the lid 150 opens toward a center of the integrated closure 120. The tamper indication membrane 210 is a molded membrane that is part of the integrated closure 120 and which provides evidence if the lid 150 has been previously open. The tamper indication membrane 210 is located at the edges between the lid 150 and the base 130 and the sidewall 140. The tamper indication membrane 210 is a membrane which tears when the tab 158 is pulled from a closed position to an open position as shown and described with respect to FIG. 3B. The base 130, the lid 150, the hinge 200, and the tamper indication membrane 210 may be made from a moldable material, where the tamper indication membrane 210 is made from moldable material which is thinner relative to the base 130, the lid 150, and the hinge 200. In an implementation, the moldable membrane may be a plastic resin and the like.

[0027] FIG. 3B shows the integrated closure 120 with the lid 150 in action accordance with some implementations. The hinge 200 of the lid 150 permits the lid 150 to be in a closed position 300, an intermediate position 310, and in an open position 320. In an implementation, the integrated closure 120 includes a retention mechanism 330 in the base 130 of the integrated closure 120 which maintains the lid 150 in the open position 320. The retention mechanism 330 may be an indentation or divot dimensioned to retain the tab 158 in the open position 320. In an implementation, the retention mechanism 330 may be a pressure or force fit mechanism. The integrated closure 120 includes a bead 340 on the lid sidewall 156 which runs along the circumference integrated closure 120. As shown and described with respect to FIG. 7 and FIG. 8, the bead 340 maintains the integrated closure 120 connected to the container 110 but permits the lid 150 to be opened and closed.

[0028] FIG. 4 is a bottom view of the integrated closure 120 of FIG. 1 in accordance with some implementations. FIG. 5A is a bottom diagram of the integrated closure 120 of FIG. 1 in accordance with some implementations. FIG. 5B is a partial bottom diagram of the integrated closure 120 of FIG. 1 in accordance with some implementations. A film or the like (collectively film) 400 is integrated on the bottom surfaces of the base 130 and the lid 150. In an implementation, the film 400 is a multilayer film. In an implementation, the film 400 is a bondable multilayer film. In an implementation, the film 400 is a heat and pressure treatable, bondable multilayer film. In an implementation, the film 400 is a multilayer plastic which is moldable and bondable to the base 130 and lid 150 as described herein.

[0029] A first portion 402 of the film 400 is bonded to a corresponding portion 412 of a bottom surface 410 of the base 130 of the integrated closure 120. A second portion 404 of the film 400 is bonded to a corresponding portion 422 of a bottom surface 420 of the lid 150 of the integrated closure 120. The second portion 404 of the film 400 is in a perforated connection or relationship with a third portion 406 of the film 400 via a perforation line 500 (e.g., the second portion 404 of the film 400 is releasably connected to the third portion 406 of the film 400). As shown in FIG. 7, the film 400 is extended and molded or welded at an inner radius of the integrated closure 120. For example, the film 400 may extend to a curved section 750 or approximate thereof so that a portion of the film 400 may be in a sandwich position between the container 110 and the lid 150, and between the container 110 and the base 130 when the integrated closure is on the container. For example, the film 400 may extend to a portion of the sidewall 140. This may maintain the third portion 406 in a stretched and stiff position when the lid 150 is opened and the second portion 404 is separated from the third portion 406. In an implementation, although a perforation line 500 is described, other mechanisms may be used including a scribe line and the like.

[0030] FIG. 6 is a view of the integrated closure 120 on the container 110 in an open position in accordance with some implementations. As shown, when the lid 150 is flipped open from the container 110, the second portion 404 of the film 400 remains bonded to the lid 150 creating an opening or hole 600 relative to the third portion 406 for dispensing material contained in the container 110. The first portion 402 remains bonded on the bottom surface 410 of the base 130, and the third portion 406 is suspended due to its connection to the first portion 402. Since the second portion 404 remains on the lid 150, waste is mitigated.

[0031] FIG. 7 is a cross-sectional view of the integrated closure and container 100 in accordance with some implementations and FIG. 8 is a cross-sectional view of an integrated closure and container 100 in accordance with some implementations. As described herein, the container 110 has a body 112, a shoulder 114, and a neck 700. The neck 700 includes a sidewall 710 and a top shoulder 720. The sidewall 710 has a first leg 712 which is offset from a second leg 714 by a length of a third leg 716, which is perpendicular to the first leg 712 and the second leg 714 and connects the first leg 712 and the second leg 714. The third leg 716 being a ledge. The offset configuration forms a groove 730. The neck 700 has a S shaped configuration.

[0032] The integrated closure 120 has a base 130, a sidewall 140, and a lid 150. The sidewall 140 and the lid 150 have a bead 340 (e.g., a bead protrusion) which engages the third leg 716 and permits the sidewall 140 and the lid 150 to fit in the groove 730. The engagement results in an audible and tactile indicator to a consumer or user that the lid 150 is snapped close with respect to the container 100.

[0033] The shoulder 114 of the container 110 is wider than the width of the integrated closure 120. This allows the integrated closure 120 to sit tightly on the shoulder 114. Consequently, the integrated closure 120 is tamper proof in that the integrated closure 120 is hard to remove from the container 110.

[0034] FIG. 9 is flowchart of a method 900 for manufacturing an integrated closure and container in accordance with some implementations. The method 900 includes molding 910 a closure at least a base, a sidewall, a lid, hinge, and a tamper evident membrane; positioning 920 a film on the closure; applying 930 heat to the film to bond the film to the base and a portion of the lid; and forming 940 a tearaway line around the portion of the lid. The method 900 may be used to make the integrated closure and containers in FIGS. 1-8, for example.

[0035] The method 900 includes molding 910 a closure including at least a base, a sidewall, a lid, hinge, and a tamper evident membrane. The integrated closure may be molded in a closed position. The tamper evident membrane may have a thinner thickness relative to the lid and/or the base, for example. The tamper evident membrane is situated between the edges of the base and the sidewall proximate to the edges of the lid such that the lid opens towards a center of the closure. The hinge is a flexible structure between an edge the base and the lid which is flexible, movable, or rotatable between the closed position and an open position and such that the lid opens towards a center of the closure. The integrated closure and container described herein may be manufactured using compression molding, injection molding and other like production processes. The integrated closure and container may be made from polypropylene, high-density polyethylene, polyethylene terephthalate (PET), moldable plastic, and the like.

[0036] The method 900 includes positioning 920 a film on the closure. The film is positioned on edge portions of the base proximate the lid and the lid. The film extends toward and around an inner radius of the closure or on a portion of the sidewall.

[0037] The method 900 includes applying 930 heat to the film to bond the film to the base and to a portion of the lid. A heat pad or the like may heat the film to bond the film to the base and to the portion of the lid. In an implementation, heat and pressure may be used. In an implementation, the portion has a defined shape.

[0038] The method 900 includes forming 940 a tearaway line around the portion of the lid to complete formation of an integrated closure. The film is perforated or scribed along the portion so that when the lid is opened, the perforated portion remains on the lid and an opening for dispensing material in the container is formed.

[0039] FIG. 10 is flowchart of a method 1000 for manufacturing an integrated closure and container in accordance with some implementations. The method 1000 includes molding 1010 a closure at least a base, a sidewall, a lid, hinge, and a tamper evident membrane; positioning 1020 a film with a perforated shape on the closure; and applying 1030 heat to the film to bond the film to the base and the lid. The method 1000 may be used to make the integrated closure and containers in FIGS. 1-8, for example.

[0040] The method 1000 includes molding 1010 a closure including at least a base, a sidewall, a lid, hinge, and a tamper evident membrane. The integrated closure may be molded in a closed position. The tamper evident membrane may have a thinner thickness relative to the lid and/or the base, for example. The tamper evident membrane is situated between the edges of the base and the sidewall proximate to the edges of the lid such that the lid opens towards a center of the closure. The hinge is a flexible structure between an edge the base and the lid which is flexible, movable, or rotatable between the closed position and an open position and such that the lid opens towards a center of the closure. The integrated closure and container described herein may be manufactured using compression molding, injection molding and other like production processes. The integrated closure and container may be made from polypropylene, high-density polyethylene, polyethylene terephthalate (PET), moldable plastic, and the like.

[0041] The method 1000 includes positioning 1020 a film with a perforated shape on the closure. The film is positioned on edge portions of the base proximate the lid and the perforated shape is positioned on the lid. The film extends toward and around an inner radius of the closure or on a portion of the sidewall.

[0042] The method 1000 includes applying 1030 heat to the film to bond the film to the base and to the lid. A heat pad or the like may heat the film to bond the film to the base and to the lid. In an implementation, heat and pressure may be used. The film is bonded so that when the lid is opened, the perforated shape remains on the lid and an opening for dispensing material in the container is formed.

[0043] The construction and arrangement of the methods as shown in the various exemplary embodiments are illustrative only. Although only a few embodiments have been described in detail in this disclosure, many modifications are possible (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters, mounting arrangements, use of materials and components, colors, orientations, etc.). For example, the position of elements may be reversed or otherwise varied and the nature or number of discrete elements or positions may be altered or varied.
