DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Flexible packaging bags with resealable zipper closures are widely available for holding a variety of products. Zipper closures on conventional bags can be easily opened and are not appropriate for use with medicines and other potentially hazardous substances. Existing child-proof zipper systems are overly complicated and can be difficult and expensive to manufacture. It should be appreciated that there is a need for an improved child-resistant closure system. The present invention fulfills this need and provides further related advantages.

The present technology relates to a resealable container that is child-proof or child-resistant. In other words, the resealable container does not allow a person without knowledge of how to properly open the resealable container to open the resealable container and get access to content within the resealable container. The resealable container can employ a female and male interlocking members that must be properly rotated to cause the interlocking members to disengage (e.g., decouple). When a person without knowledge on how to properly open the resealable container attempts to open the resealable container in a sealed configuration, the interlocking members do not properly rotate to cause disengagement of the interlocking members. Alternatively, when a person with knowledge attempts to open the resealable container, the interlocking members can be properly rotated to cause the disengagement.

With reference to FIGS. 1-6 of the illustrative drawings, there is shown a resealable container 100 having a child-resistant closure system according to one embodiment. The resealable container 100 can include a first wall 10 and a second wall 20 opposing each other. The first and second walls 10, 20 can be sealed together (e.g., heat-sealed) along respective side edges 31, 32 and a bottom edge 33 of the sealed first and second walls 10, 20 such that interior surfaces 34, 35 of the first and second walls 10, 20 form a storage space 40 therebetween. In one embodiment, each of the first wall 10 and the second wall 20 is made of a unitary sheet. A top edge 36 of the first wall 10 and a top edge 37 of the second wall 20 can define an opening 45 for the storage space 40. The first wall 10 and the second wall 20 can comprise respective interior surfaces 34, 35.

Although the resealable container 100 is shown as a rectangular form, it is understood that the resealable container 100 can have other forms. For example, the resealable container 100 can be triangular form, pentagonal form, hexagonal form, halfmoon-like form, or the like. The container 100 can comprise various materials, including thermoplastic films such as polyethylene. Different parts or portions of the resealable container 100 can be made of flexible, semi-flexible, semi-stiff, or stiff materials.

With particular reference to the perspective view of the resealable container 100 in FIG. 1, the resealable container 100 can provide an opening along an axis 2A. The inner surfaces 34, 35 of the respective first wall 10 and second wall 20 can be pulled along directions 3A and 3B to provide the opening 45.

With particular reference to the cross-sectional side views of the resealable container 100 in FIGS. 2A and 2B, the resealable container 100 can further comprise a closure strip assembly 70. The closure strip assembly 70 can comprise a first lateral interlocking member 80 and a second lateral interlocking member 90. The interlocking members 80, 90 can be laterally positioned along an axis (e.g., the axis 2A of FIG. 1) as illustrated in FIGS. 3A and 3B. The first lateral interlocking member 80 can be mechanically coupled (e.g., engaged) with the second lateral interlocking member 90 to seal the opening 45 of the container 100 in a sealed configuration. Further, the first lateral interlocking member 80 can be mechanically decoupled (e.g., disengaged) from the second lateral interlocking member 90 to provide the resealable container 100 in an opened configuration that allows access into the opening 45. Operations of the interlocking members are further described in relation to FIGS. 5 and 6.

In one embodiment, the first lateral interlocking member 80 can comprise an attached portion 82 and a free portion 83 opposite the attached portion 82. In some embodiments, the attached portion 82 of the first lateral interlocking member 80 can be directly attached to a first extension strip 50, but the free portion 83 of the first lateral interlocking member 80 may not directly attached to the first extension strip 50. As the attached portion 82 is attached to the first extension strip 50 but the free portion 83 is not, when the resealable container 100 is attempted to be opened, by an outward force applied to the first extension strip 50 along axis 3A of FIG. 1, the free portion 83 can be rotated along a trajectory 2B of FIG. 2A. The first extension strip 50 can comprise a first edge 51 and a second edge 52. The first edge 51 and the second edge 52 can be termed “edges” as they can be seen in FIG. 3A along the axis 2A in FIG. 1 of the resealable container 100. The first edge 51 of the first extension strip 50 can be attached to the interior surface 34 of the first wall 10 below the top edge 36 of the first wall 10. The second edge 52 of the first extension strip 50 can be at a location between the first edge 51 of the first extension strip 50 and the top edge 36 of the first wall 10.

A portion of the first wall 10 that extends above the first edge 51 to the top edge 36 can define a first flap 11 of the first wall 10. At least a portion of the first extension strip 50 between the second edge 52 and the first lateral interlocking member 80 is attached to the inner surface 34 of the first wall 10. In one embodiment, the attached portion 82 of the first lateral interlocking member 80 can be attached to the first extension strip 50 at a location between the first and second edges 51, 52 of the first extension strip 50. FIG. 6 provides additional visual aid of the first extension strip 50, the first flap 11, and the first lateral interlocking member 80 of the closure strip assembly 70.

In one embodiment, the second lateral interlocking member 90 can comprise an attached portion 92 and a free portion 93 opposite the attached portion 92 of the second lateral interlocking member 90. In some embodiments, the attached portion 92 of the second lateral interlocking member 90 can be attached to a second extension strip 60, but the free portion 93 of the second lateral interlocking member 90 is not directly attached to the second extension strip 60. As the attached portion 92 can be directly attached to the second extension strip 60 but the free portion 93 may not be, when the resealable container 100 is attempted to be opened, by an outward force applied to the second extension strip 60 along axis 3B of FIG. 1, the free portion 93 can be rotated along a trajectory 2B of FIG. 2A.

The second extension strip 60 can comprise a first edge 61 and a second edge 62. The first edge 61 and the second edge 62 can be termed “edges” as they can be seen in FIG. 3B along the axis 2A in FIG. 1 of the resealable container 100. The first edge 61 of the second extension strip 60 can define a portion of the interior surface 35 of the second wall 20 and a portion of the second extension strip 60 that are attached to each other above the second lateral interlocking member 90. The second edge 62 of the second extension strip 60 can be at a location opposite the first edge 61 of the second extension strip 60, between the first edge 61 of the second extension strip 60 and the bottom edge 33 of the second wall 20. The second edge 62 of the second extension strip 60 can define a portion of the second extension strip 60 from the first edge 61 of the second extension strip 60 toward the second lateral interlocking member 90.

A portion of the second wall 20 from the top edge 37 to the second edge 62 can define a second flap 21 of the second wall 20. In one embodiment, the attached portion 92 of the second lateral interlocking member 90 can be attached to the second extension strip 60 at a location below the first and second edges 61, 62 of the second extension strip 60. FIG. 6 provides additional visual aid of the second extension strip 60, the second flap 21, and the second lateral interlocking member 90 of the closure strip assembly 70.

With particular reference to the cross-sectional front views of the resealable container 100 in FIGS. 3A and 3B, the first lateral interlocking member 80 can be attached to the first extension strip 50 above the first edge 51 of the first extension strip 50 and below the second edge 52 of the first extension strip 50. In contrast, the second lateral interlocking member 90 can be attached to the second extension strip 60 below the second edge 62 of the second extension strip 60. In one embodiment, a portion of the first extension strip 50 between the first lateral interlocking member 80 and the first edge 51 of the first extension strip 50 is not attached to the first wall 10. In another embodiment, a portion 55 of the first extension strip 50 between the first lateral interlocking member 80 and the second edge can be heat-sealed to the first wall 10, and a portion of the first extension strip 50 between the first lateral interlocking member 80 and the heat-sealed portion 55 is not coupled to the first wall 10. Similarly, a portion 65 of the second extension strip 60 between the second lateral interlocking member 90 and the first edge 61 of the second extension strip 60 can be heat-sealed to the second wall 20, and a portion of the second extension strip 60 between the second lateral interlocking member 90 and the heat-sealed portion 65 is not attached to the second wall 20.

When referring to an “edge”, the “edge” is referred to as an “edge” because it is attached to a wall to define an attachment edge for an extension strip. For example, the first edge 51 of the first extension strip 50 is attached to the first wall 10 to define an attachment edge for the first extension strip 50. However, it should be understood that the first extension strip 50 and the second extension strip 60 can include material that extends below this attachment edge 51, as illustrated by portion 56.

With particular reference again to the detailed cross-sectional side view of the resealable container 100 in FIG. 2B, the closure strip assembly 70 can comprise the first lateral interlocking member 80 and the second lateral interlocking member 90. In one embodiment, the first lateral interlocking member 80 can comprise at least two asymmetrical female strips or channels 81, and the second lateral interlocking member 90 can comprise at least two asymmetrical male strips or beads 91 that correspond to the at least two asymmetrical female strips or channels 81. Each of the at least two asymmetrical female channels 81 can comprise a first J-shaped member 84, and each of the at least two asymmetrical male beads 91 can comprise a second J-shaped member 94. The first J-shaped member 84 and the second J-shaped member 94 can face opposite directions. For example, as illustrated in FIG. 2B, the first J-shaped member 84 can face the bottom edge 33 of the first wall 10, and the second J-shaped member 94 can face the top edge 37 of the second wall 20.

The first J-shaped member 84 can engage the second J-shaped member 94 when the first lateral interlocking member 80 is operatively connected to the second lateral interlocking member 90 in a sealed configuration. When the first lateral interlocking member 80 and the second lateral interlocking member 90 are engaged, the first J-shaped member 84 and the second J-shaped member 94 cannot be disengaged without going through a proper disengagement process. Accordingly, the closure strip assembly 70 can provide child-resistance for the resealable container 100.

The first and second lateral interlocking members 80, 90 can be operable to disengage each other when the female interlocking strip 81 is caused to rotate relative to the male interlocking strip 91 so that the first J-shaped member 84 disengages from the second J-shaped member 94 in an opened configuration. For example, the first and second lateral interlocking members 80, 90 can be operable to disengage each other when the female interlocking strip 81 is caused to rotate relative to the male interlocking strip 91 such that a free end 85 of the first J-shaped member 84 rotates toward the top edge 36 of the first wall 10 (e.g., counter-clockwise in FIG. 2B) and a free end 95 of the second J-shaped member 94 rotates toward the bottom edge 33 of the second wall 20 (e.g., counter-clockwise in FIG. 2B).

With particular reference to the cross-sectional side views of the resealable container 100 in FIGS. 4 and 5, the first and second lateral interlocking members 80, 90 described above are configured to become disengaged (e.g., disconnected) from each other when the first flap 11 and the second flap 21 are pulled apart from each other as the second extension strip 60 is held against the interior surface 35 of the second wall 20. When the second extension strip 60 is held down in this way, as the first and second flaps 11, 21 are pulled apart, the first and second lateral interlocking member 80, 90 are permitted to rotate relative to each other such that they can become disengaged. In one embodiment, the first extension strip 50 should be held against the interior surface 34 of the first wall 10 as well during the pulling apart to disengage the first and second lateral interlocking members 80, 90. A person may hold either or both the first extension strip 50 against the interior surface 34 of the first wall and the second extension strip 60 against the interior surface 35 of the second wall 20 at a location close to the first and second lateral interlocking members 80, 90 to effectuate the rotational movement of the members 80, 90. In this way, a relative rotation between the first and second lateral interlocking members 80, 90 can be maximized.

In contrast, with particular reference to the cross-sectional side view of the resealable container 100 in FIG. 6, the first and second lateral interlocking members 80, 90 described above are configured to remain operatively connected when the first flap 11 and the second flap 21 are pulled apart without also holding at least the second extension strip 60 against the interior surface 35 of the second wall. 20. When the first and second flaps 11, 21 are pulled in this way, the second extension strip 60 is allowed to be pulled away from the second wall 20, thus minimizing the relative rotation between the first and second lateral interlocking members 80, 90. As illustrated, a person may not be able to provide the relative rotation needed to disengage the first and second lateral interlocking members 80, 90.

It should be appreciated from the foregoing description that the present invention provides an improved child-resistant closure system.
