Definitions
- the present disclosure relates to closures, reclosures or zippers for flexible packaging which is child-deterrent or child-resistant.
- a profile of the closure, reclosure or zipper includes tabs which are partially cut from the flange and includes upper and lower press-to-close interlocking elements, on respective upper and lower portions of the flange, for engagement with the opposing profile.
- a closure, reclosure or zipper typically configured as a press-to-close zipper, with a tab created from flange material on one of the profiles, between upper and lower sets of interlocking elements.
- the closure, reclosure or zipper is opened by a user grasping the tab and pulling apart the first and second profiles, thereby releasing the press-to-close interlocking elements.
- Figure 1A is a side plan view of a two-piece press-to-close zipper or reclosure of an embodiment of the present disclosure.
- Figure 1B is an end view of a two-piece press-to-close zipper or reclosure of an embodiment of the present disclosure.
- Figure 2 is a schematic illustrating the tab extended so as to overlap with the lower interlocking elements in an embodiment of the present disclosure.
- Figure 3 illustrates the removal of a semi-circular portion of the top flange around the tab.
- Figure 4 is a schematic of a further embodiment of the present disclosure, wherein an aperture for finger insertion is provided.
- Figure 5 is a schematic of a still further embodiment of the present disclosure wherein a slit for finger insertion is provided.
- Figures 1A and 1B illustrate a two-piece press-to-close zipper 10 (or similar closure or reclosure), typically made of a polymeric material, with a first profile 11 and a second profile 13.
- the first profile 11 includes first upper interlocking element 12 and first lower interlocking element 14 on respective upper and lower edges of the first flange 16.
- Adjacent to, or partially overlapping, the upper interlocking element 12 is a semi-circular or similarly shaped (e.g., U-shaped or C- shaped) slit 20 cutting through the first flange 16, thereby forming tab 22, with a portion of the tab 22 remaining integral with or attached to first flange 16 or first profile 11.
- second profile 13 includes second flange 18 with second upper and lower interlocking elements 15, 17.
- First and second press-to-close upper interlocking elements 12, 15 interlock with each other in the closed configuration of the press-to-close zipper 10.
- first and second press-to-close lower interlocking elements 14, 17 interlock with each other in the closed configuration of the press-to-close zipper 10. While some configurations may include a tab structure on both first and second flanges 16, 18, typically the tab structure is included on only one flange.
- second profile 13 is attached below the top of a bag mouth at a point on the joining flange, the upper half of the zipper 10 is attached to the bag by a sealing flange or guiding and sealing flange extension 24 below the first lower interlocking element 14 (see Figure 3).
- This sealing arrangement creates a shearing action between the first and second profiles 11, 13 when both bag walls are separated, as when opening a typical bag, the shearing action preventing or inhibiting the first and second profiles 11, 13 from separating and the zipper 10 (and thus the bag, package, pouch or similar container) from opening.
- first flange 16 of first profile 11 could also be attached to the walls of the bag, package, pouch or similar container between the first upper and lower interlocking elements 12, 14 as long as the seal between the first flange 16 and the bag wall is sufficiently below the inverted tab 22 to allow the tab 22 to be grasped.
- the lower zipper half of first profile 11 could be attached by an upper flange, and may, in some embodiments, be attached to the guiding and sealing flange extension 24 as shown in Figure 3.
- Figure 2 illustrates the tab 22 extended down to a point where it overlaps the lower interlocking element 14. This locks the free end of the tab 22 into the lower bottom interlocking element 14, increasing the difficulty of opening the zipper 10 due to the need to first unlock the overlapped portion of the tab 22 in order to be able to subsequently grasp the tab 22 and open the press-to-close zipper 10.
- Figure 3 illustrates that a semi-circular portion 23 of the first flange 16 around the tab 22 (inwardly of the slit 20 and outwardly of tab 22) can be removed thereby forming a gap between a portion of the tab 22 and the first flange 16 in order make accessing the tab 22 easier.
- Figure 3 further illustrates the guiding and sealing flange extension 24 below the lower interlocking element 14 of the first flange 16. The guiding and sealing flange extension 24 providing attachment points for the zipper 10 as well as aiding in guiding the zipper 10 during production of packages.
- This reclosure or zipper 10 therefore includes a tab 22 created from material from first flange 16 between first upper and lower interlocking elements 12, 14.
- opening the zipper 10 is non-intuitive for operation by a child.
- the sealing of the zipper 10 to the package walls is done in a way that pulling on the bag walls above or below the zipper 10 will not open the zipper 10.
- Figures 4 and 5 illustrate alternatives wherein the first flange 16 includes a finger aperture 30 (see Figure 4, which may include a second finger aperture 31, shown in phantom, offset from first finger aperture 30, on the second flange 18) or a finger slit 32 ( Figure 5).
- a finger aperture 30 see Figure 4, which may include a second finger aperture 31, shown in phantom, offset from first finger aperture 30, on the second flange 18
- a finger slit 32 Figure 5
- This allows a user to insert a finger through the aperture 30 or 31 or finger slit 32 and force the first and second profiles 11, 13 apart (i.e., separating upper first and second interlocking elements 12, 15 from other and separating lower first and second interlocking elements 14, 17 from each other) thereby opening the zipper 10 a manner that would not be expected to be intuitive for a child.
