Rather, the terms are used merely to indicate that the male and female fitments 12, 14 can form a snap fit when joined together. Also, whereas in the following embodiment the male fitment 12 comprises an elongated rib-like structure and the female fitment 14 comprises an elongated C-shaped structure that defines a channel, the configurations could be reversed. Finally, it should be appreciated that the male and female fitments 12, 14 may be any two shapes that form a snap fit when joined together.
Referring again to Figure 1, in the illustrated embodiment the male fitment 12 comprises an elongated rib-like structure 16, preferably one that is cylindrical and has a circular cross section, attached to a flat mounting plate 18. As explained below, the male mounting plate 18 is adhered to an outer facing surface of the flexible package 20 by
6 adhesive, hot melt or any other suitable means. The male mounting plate 18 has a vertical height (H) and a length, where the length dimension corresponds to the package width.
The female fitment 14 comprises an elongated C-shaped structure 22 having substantially parallel edges 23 defining a gap or opening 24. The C-shaped structure also defines an elongated groove or channel 26 configured to receive and engage the rib-like structure 16. The C-shaped structure 22 is tangentially attached to a flat mounting plate 28 located opposite the gap 24. The mounting plate 28 can be adhered to an outer facing surface of the flexible package 20 by adhesive, hot melt or any other suitable means.
Preferably the C-shaped structure 22 is made of a resilient plastic material that can flex and return to its original shape. The female mounting plate 28 has a vertical height and a length. The lengths of the male and female mounting plates 18, 28 preferably are substantially the same as the width (W) of the package 20.
Figure 2 is a perspective view of a container 11 comprising a flexible package and the snap fitment system 10 of Figure 1. The flexible package 20 comprises a front wall or panel 32 and a rear wall or panel 34 connected by opposing side walls 36, a top portion 38 and a bottom (not shown in the figures). The package 20 may hold any suitable contents, including without limitation coffee, cookies, crackers and other snack foods. The top portion 38 includes a top end 40 where the front wall 32 and rear wall 34 come together to form a seal. The top end 40 may be formed by crimping and heat sealing the front and rear walls 32, 34. The top end 40 terminates in a top edge 42.
The top (upper) portions 38 of the front and rear walls 32, 34 may be pulled apart
The female fitment 14 comprises an elongated C-shaped structure 22 having substantially parallel edges 23 defining a gap or opening 24. The C-shaped structure also defines an elongated groove or channel 26 configured to receive and engage the rib-like structure 16. The C-shaped structure 22 is tangentially attached to a flat mounting plate 28 located opposite the gap 24. The mounting plate 28 can be adhered to an outer facing surface of the flexible package 20 by adhesive, hot melt or any other suitable means.
Preferably the C-shaped structure 22 is made of a resilient plastic material that can flex and return to its original shape. The female mounting plate 28 has a vertical height and a length. The lengths of the male and female mounting plates 18, 28 preferably are substantially the same as the width (W) of the package 20.
Figure 2 is a perspective view of a container 11 comprising a flexible package and the snap fitment system 10 of Figure 1. The flexible package 20 comprises a front wall or panel 32 and a rear wall or panel 34 connected by opposing side walls 36, a top portion 38 and a bottom (not shown in the figures). The package 20 may hold any suitable contents, including without limitation coffee, cookies, crackers and other snack foods. The top portion 38 includes a top end 40 where the front wall 32 and rear wall 34 come together to form a seal. The top end 40 may be formed by crimping and heat sealing the front and rear walls 32, 34. The top end 40 terminates in a top edge 42.
The top (upper) portions 38 of the front and rear walls 32, 34 may be pulled apart
7 or otherwise separated to break the seal and create an opening to access the contents of the package 20. After opening, it may be desired to reseal the package 20 in accordance with this disclosure.
Still referring to Figure 2, the male fitment 12 and the female fitment 14 are adhered to the outer facing surfaces 33, 35 respectively of the front and rear panels 32, 34.
For example, in the illustrated embodiment, the male fitment 12 is adhered to the outer facing surface 33 of the front wall 32 and the female fitment 14 is adhered to the outer facing surface 35 of the rear wall 34. Alternatively, the male fitment 12 may be adhered to the rear wall 34 and the female fitment may be adhered to the front wall 32.
In a key aspect of the disclosure, the interlocking structures of the male and female fitments 12, 14 face outward, away from the package 20, so the flexible package must be folded over to be closed. For example, in the illustrated embodiment, the mounting plate 18 of the male fitment 12 is adhered to the front wall 32 so that the rib-like structure 16 faces outward, away from the package 20. Likewise, the mounting plate 15 28 of the female fitment 14 is adhered to the rear wall 34 so that the gap 24 defined by the C-shaped structure 22 faces outward, away from the package 20.
In Figure 2 the male fitment 12 is adhered to the front wall 32 along the heat sealed top end 40 and the female fitment 14 is adhered to the rear wall 34 near the heat sealed top end 40 but at a distance (D) below the top end 40. The female fitment 14 20 should be located a sufficient distance from the top edge 42 to allow the portion of the package 20 carrying the male fitment 12, typically the heat sealed top end 40, to be folded over (in the direction of the female fitment 14) until the male fitment 12 engages the
Still referring to Figure 2, the male fitment 12 and the female fitment 14 are adhered to the outer facing surfaces 33, 35 respectively of the front and rear panels 32, 34.
For example, in the illustrated embodiment, the male fitment 12 is adhered to the outer facing surface 33 of the front wall 32 and the female fitment 14 is adhered to the outer facing surface 35 of the rear wall 34. Alternatively, the male fitment 12 may be adhered to the rear wall 34 and the female fitment may be adhered to the front wall 32.
In a key aspect of the disclosure, the interlocking structures of the male and female fitments 12, 14 face outward, away from the package 20, so the flexible package must be folded over to be closed. For example, in the illustrated embodiment, the mounting plate 18 of the male fitment 12 is adhered to the front wall 32 so that the rib-like structure 16 faces outward, away from the package 20. Likewise, the mounting plate 15 28 of the female fitment 14 is adhered to the rear wall 34 so that the gap 24 defined by the C-shaped structure 22 faces outward, away from the package 20.
In Figure 2 the male fitment 12 is adhered to the front wall 32 along the heat sealed top end 40 and the female fitment 14 is adhered to the rear wall 34 near the heat sealed top end 40 but at a distance (D) below the top end 40. The female fitment 14 20 should be located a sufficient distance from the top edge 42 to allow the portion of the package 20 carrying the male fitment 12, typically the heat sealed top end 40, to be folded over (in the direction of the female fitment 14) until the male fitment 12 engages the
8 female fitment 14. This distance (D) may be a little more than twice the height (H) of the male mounting plate 18.
To close the package 20, the top end 40 is folded over twice until the male fitment 12 can engage and form a snap fit with the female fitment 14. Fitting the male fitment 12 to the female fitment 14 may cause an audible click, which can assure the consumer that a good seal has been achieved.
Figure 3 is a perspective view of the flexible package of Figure 2 after the top end 40 has been folded in the direction of the female fitment 14 until the top end 40 lays flat against the rear wall 34. The rib-like structure 16 of the male fitment 12 now faces rearward. The C-shaped structure 22 remains facing substantially rearward.
Figure 4 is a perspective view of the flexible package of Figure 3 after the top end 40 has been folded over a second time. The rib-like structure 16 is aligned with and faces the gap 24 in the C-shaped structure 22.
Figure 5 is a perspective view of the flexible package of Figure 4 after the snap fitments have been joined together to seal the package 20. The rib-like structure 16 has been snap fitted into the C-shaped structure 22 by a user to engage the C-shaped structure 22 and seal the package 20. Notably, the rib-like structure 16 and the C-shaped structure 22 are in direct engagement; there are no layers of packaging material between the rib-like structure 16 and C-shaped structure 22. More importantly, the male and female fitments 12, 14 hold the front and rear walls 32, 34 of the top portion 38 of the package 20 in close sealing engagement with each other, thereby providing an almost airtight seal.
