DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings in detail wherein like numerals indicate like elements throughout the several views, one sees that FIG. 1 is a perspective view of the first embodiment of the package 10 of the present disclosure. Package 10 includes a semi-rigid or rigid container portion 12 and a plastic or polymer reclosable header 14. The typical materials of the container portion 12 and the reclosable header 14 are described in the commonly-owned prior art listed above. However, the prior art typically included a container portion with a square or rectangular opening or mouth for receiving the header 14. However, in the embodiment of FIG. 1, the semi-rigid or rigid container portion 12 has a circular shape, as viewed from above, thereby forming a circular mouth for receiving the reclosable header 14. Other possible envisioned shapes include oval-shaped, hexagonal, orthogonal and triangular.
In the embodiment illustrated in FIG. 2, the semi-rigid or rigid container portion 12 includes front wall 20, rear wall (not illustrated), corresponding to the rear front wall 20, and side walls 22. While the commonly-owned prior art discloses containers with planar walls which are frequently substantially or nearly orthogonal with each other, FIG. 2 discloses the front wall 20, as well as unillustrated corresponding co-extensive rear wall, with an hourglass shape formed by inwardly concave side edges and arcuate side walls 22 which follow the inwardly concave side edges of front wall 20. A rectangular mouth is presented for receiving the polymer reclosable header 14, which includes reclosure 34, which may be, but is not limited to, a zipper. It is envisioned that most, if not all, of the zippers discussed in the commonly-owned prior art would be applicable to this embodiment.
In the embodiment illustrated in FIG. 3, the semi-rigid or rigid container portion 12 is presented with a rectangular or orthogonal shape. However, the reclosable header 14 has a fitment 24 inserted with the top fold or top seam 26 in order to provide a pour spout for liquid, granular or similar contents of the package 10. Alternatively, the fitment 24 may be inserted into an upper portion of one of the side seams 30 of the reclosable header 14. The semi-rigid or rigid container 12 is envisioned to be the same or substantially the same as those disclosed in the commonly-owned application or other embodiments disclosed herein.
In the embodiment illustrated in FIG. 4, the reclosable header 14 is releasably attached to the semi-rigid or rigid container portion 12 by a tear tape 32 or similar attachment device such as, but not limited to, a peelable seal (rather than a typical adhesive, heat sealing, or similar method). Similarly, a score line or line of weakness could be provided in the reclosable header 14, near the area of joinder with respect to the semi-rigid or rigid container portion. This use of tear tape 32 or similar attachment device allows the user to remove the reclosable header 14 from the semi-rigid or rigid container 12 after consumer use in order to facilitate recycling. Other than for the method of attachment between the header 14 and the semi-rigid or rigid container portion 12, it is envisioned that the header 14 and semi-rigid or rigid container portion 12 are typically the same or substantially the same as those disclosed in the commonly-owned prior art or the other embodiments disclosed herein.
In the embodiment illustrated in FIG. 5, the reclosable header 14, rather than including a reclosure on the top fold or top seam 26, the zipper or reclosure 34 is provided on a front panel of the reclosable header 14. The zipper or reclosure 34 may have many configurations, including, but not limited to, being attached to the inside or outside of the front panel, and may be a slider zipper, a press-to-close zipper, or many other possible zipper configurations. There are many advantages to this type of zipper application because the zipper can be applied prior to the film being folded, segments of the zipper can be applied in lieu of a continuous strip of zipper, etc. The semi-rigid or rigid container 12 is envisioned to be the same or substantially the same as those disclosed in the commonly-owned application or other embodiments disclosed herein.
In the embodiment illustrated in FIG. 6, one of the edges or side seals of the reclosable header 14 is replaced with a gusset 36 wherein two interior walls form a V-configuration. While FIG. 6 illustrates a single gusset 36, it is envisioned that this embodiment may include a gusset on each side of the reclosable header 14. The gusset 36, combined with the sidewalls of header 14, forms a Y-configuration with two arms. The arms may be pushed toward each other to form a closed configuration. Likewise, the material from the arms may be folded outwardly or opened to provide a pour spout (see the left hand side of FIG. 6C), which may be very convenient for flakey or grainy products, such as, but not limited to, cereal or similar food products. In such a configuration, the zipper may be partially attached to the header 14. A further advantage of the gusset 36 is that there is less overhang from the gusset 36 as compared to prior designs. FIG. 6A is a cross-sectional top view showing how a single gusset 36 can have a dedicated zipper or reclosure 34′. FIG. 6B is a cross-sectional top view of a zipper or reclosure 34″ extending along a length of the front or rear of the interior of the reclosable header 14. FIG. 6C is a cross-sectional top view of a zipper or reclosure 34′″ extending around the entire internal periphery of the reclosable header 14. The semi-rigid or rigid container 12 is envisioned to be the same or substantially the same as those disclosed in the commonly-owned application or other embodiments disclosed herein.
In the embodiment illustrated in FIG. 7, the semi-rigid or rigid container portion 12 is substantially shallower (i.e., of reduced height) than the containers of the prior art, thereby creating a tray-like configuration. Other than for the height of the semi-rigid or rigid container portion 12, it is envisioned that the header 14 and semi-rigid or rigid container portion 12 are typically the same or substantially the same as those disclosed in the commonly-owned prior art or the other embodiments disclosed herein.
In the embodiment illustrated in FIG. 8, the bottom of the semi-rigid or rigid container portion 12 is provided by tray-like plug 40, which may be attached or disattached from the semi-rigid or rigid container portion 12. Tray-like plug 40 is typically made from material similar to that of the semi-rigid or rigid container portion 12, and likewise may be coated with heat sealable material for heat sealing to the semi-rigid or rigid container portion 12. Tray-like plug 40 includes a planar lower floor 42 which serves as the bottom of the semi-rigid or rigid container portion 12. The planar lower floor 42 is typically rectangular in order to correspond to the open bottom of the semi-rigid or rigid container portion 12. Of course, different shapes of the open bottom would likewise typically require a corresponding shape of the planar lower floor 42. Tray-like plug 40 further includes sidewalls 44 extending upwardly (or perpendicularly) about the periphery of lower floor 42. The plug 40 could slide up into the base of the semi-rigid or rigid container portion 12 so that the sidewalls 44 are inside of the semi-rigid or rigid container portion 12 (that is, adhesive on the outside of sidewalls 44 would contact the interior of semi-rigid or rigid container portion 12). Alternatively, the base of the semi-rigid or rigid container portion could fit inside of the sidewalls 44 (that, is adhesive on the inside of sidewalls 44 would contact the exterior of semi-rigid or rigid container portion 12). Of course, heat sealing may be substituted for the adhesive joining. A mandrel may be used to assist in the sealing of the semi-rigid or rigid container portion 12 to the plug 40. These configurations could also be used in fill from the bottom embodiments. That is, semi-rigid or rigid container portion 12 would be inverted with an open bottom facing upwardly (with header 14 attached and closed, facing downwardly), the package 10 would be filled with product through this open bottom and then the tray-like plug 40 would be glued or otherwise secured to the semi-rigid or rigid container portion 12 thereby sealing the package 10. Other than for the construction of the bottom of the semi-rigid or rigid container portion 12, it is envisioned that the header 14 and semi-rigid or rigid container portion 12 are typically the same or substantially the same as those disclosed in the commonly-owned prior art or the other embodiments disclosed herein.
Thus the several aforementioned objects and advantages are most effectively attained. Although preferred embodiments of the invention have been disclosed and described in detail herein, it should be understood that this invention is in no sense limited thereby and its scope is to be determined by that of the appended claims.
