Description
- 1. Field of the Invention
- The present invention relates generally to the packaging art, and more particularly to a reclosable zipper of a type used to close a mouth of a bag.
- 2. Description of the Related Art
- Packaging materials with reclosable plastic zippers that are opened by peeling and resealed by pressing are widely used as packaging bags for granular, powdery and other solid materials mainly due to their light weight and relatively low cost. Although there are a wide variety of reclosable plastic zippers used in packaging materials, most of them are rendered inoperable if the packaged material comes in contact with the zipper as it is inserted into or removed from the bag. Particularly, granular or powdery materials have a tendency to clog the mating portions of the zipper, rendering the zipper inoperable. The limitations specifically minimized and/or eliminated by the present invention include the inoperability of a reclosable zipper due to the insertion or removal of granular and powdery packaged materials from a packaging bag.
- According to the present invention, a reclosable zipper is provided that includes a female portion having a first base that defines a continuous groove, and a male portion that includes a second base and a male rib. The male rib extends outwardly from the second base for insertion into the continuous groove of the female portion and is locked therein when the male and female portions are pressed together. A protective flange extends outwardly from at least one of the first and second bases proximate the male rib or continuous groove of the reclosable zipper.
- In one embodiment of the present invention, the female portion includes a pair of female hooks that extend outwardly from the first base, wherein the pair of female hooks define the continuous groove. One of the female hooks extends outwardly from the first base a greater distance that the other female hook. The protective flange extends outwardly from the second base proximate the male rib.
- When the zipper is employed in a packaging bag, such as a reclosable plastic bag, the longer female hook and protective flange deflect a granular or powdery packaged material away from the male and female portions, which inhibits clogging of the male and female portions and allows the zipper to be closed without interference.

Becausemale rib 28 must be pressed intogroove 22, it is preferred, but not required, thatmale rib 28 be more rigid thanfemale hooks female hooks male rib 28 to allow them to flex and accommodate insertion ofmale rib 28 therebetween. However, it will be appreciated that a single material may be employed to manufacturezipper 10, the properties of this material exhibiting a balance between the rigidity preferred formale rib 28 and the elasticity preferred forfemale hooks - For convenience of description,
reclosable zipper 10 is described as having amale rib 28 and afemale groove 22, wherein ahead portion 30 of themale rib 28 is received by thefemale hooks female groove 22, but it will be understood and appreciated by those of skill in the art that certain principles of the invention may apply to other modified forms of the zipper closure. Similarly, it will be appreciated that the claims are not limited to the specific form of the rib and groove illustrated in the drawings and described herein. - As illustrated in the embodiment of FIG. 1,
male portion 14 is also provided with aprotective flange 32 that extends outwardly fromsecond base 26.Protective flange 32 is provided proximatemale rib 28, but not too close as to inhibit insertion ofmale rib 28 intogroove 22.Protective flange 32 extends fromsecond base 26 at least the same distancemale rib 28 extends fromsecond base 26 and preferably slightly farther, for reasons that will be detailed below.Protective flange 32 may be disposed substantially perpendicular tosecond base 26, as shown in FIG. 1, or at least a portion if not all ofprotective flange 32 may be disposed at some angle relative tosecond base 26. - A
support flange 34 also extends fromsecond base 26 to support the portion offirst base 16 proximatefemale hooks Support flange 34 cooperates withprotective flange 32 to supportmale rib 28 ingroove 22, and functionally inhibits unintentional separation of male andfemale portions - FIG. 2 illustrates another embodiment of the present invention. In this embodiment, a
zipper 10′ is provided that includes afemale portion 12′ having afirst base 16′ and amale portion 14′ having asecond base 26′. Unlikezipper 10 described above, both first andsecond bases 16′, 26′ include aprotective flange 32A and 32B, respectively. Also, unlike thefemale portion 12 ofzipper 10 described above,female portion 12′ ofzipper 10′ may includefemale hooks 18′, 20′ that are substantially the same length. - FIG. 3 illustrates another embodiment of the present invention. In this embodiment, a
zipper 10″ is provided that includes afemale portion 12″ having afirst base 16″ and amale portion 14″ having asecond base 26″. Unlikezippers second base 26″ includes a pair ofprotective flanges male rib 28″. Additionally,first base 16″ includes aprotective flange 32E that is longer thanprotective flange 32D. Alternatively, as shown in FIG. 4,protective flange 32E may be shorter thanprotective flange 32D. - Referring to FIG. 5, first and
second bases elongated flanges second bases Flanges zipper 10 to a packaging bag.Flanges zipper 10 may be secured to the packaging bag by heat welding, ultrasonic welding or other known process for securing one polymeric material to another. Although not illustrated, it will be appreciated that any of the embodiments shown in FIGS. 2-4 may also be integrally formed withflanges - FIGS. 6 and 7 illustrate a
flexible bag 44 of lightweight plastic, such as polyethylene or like polymer, having areclosable zipper 10 according to the principles of the present invention. The plastic used as the material forzipper 10 may be the same type or a different type of plastic used for the main body of the bag as long as it exhibits the material properties need forzipper 10 to function. Preferably, to the portion of the zipper which should exhibit high rigidity is employed a plastic having a high rigidity, while to the portion thereof which should exhibit elasticity is employed a plastic exhibiting the required elastic properties. However, it will be appreciated that a single material may be employed to manufacturebag 44, the properties of this material exhibiting a balance between the properties preferred for the respective portions of the zipper. -
Bag 44 includes a pair of opposingside walls openable mouth 46.Mouth 46 includes the elongatereclosable zipper 10 extending across the inside thereof.Female portion 12 andmale portion 14 ofzipper 10 are shown in FIGS. 6 and 7 as being non-interlocked. - In FIGS. 6 and 7, the longer
female hook 18 andprotective flange 32 are positioned inwardly ofgroove 22 andmale rib 28, respectively, toward the inside ofbag 44. To fillbag 44 with a packagedmaterial 48, as shown in FIG. 6, anend 50 of afill tube 52 is inserted intobag 44 pastprotective flange 32 and the longerfemale hook 18. Thus, asbag 44 is filled, none of the packagedmaterial 48 comes into contact withmale rib 28 andfemale groove 22 ofzipper 10, allowingzipper 10 to be closed without interference. - When
bag 44 is emptied, as shown in FIG. 7,protective flange 32 and the longerfemale hook 18 deflect the packagedmaterial 48 away from the male and female portions ofzipper 10. Specifically, becauseprotective flange 32 is longer thanmale rib 28, the packagedmaterial 48 is completely deflected away frommale rib 28. Similarly, becausefemale hook 18 is longer thanfemale hook 20, the packaged material 38 is completely deflected away fromgroove 22. Thus, asbag 44 is emptied, none of the packagedmaterial 48 becomes attached to or clogsmale rib 28 orfemale groove 22, allowingzipper 10 to be re-closed without interference. - Alternatively, although not illustrated, each portion of
zipper 10 may be inverted such thatprotective flange 32 and the longerfemale hook 18 face the opening ormouth 46 or outside ofbag 44. This configuration would be useful where the bag is emptied using a suction tube that is inserted pastmale rib 28 andfemale groove 22, and is filled in a manner that would normally allow the packaged material to contactmale rib 28 andfemale groove 22, but for theprotective flange 32 and the longerfemale hook 18 deflecting the packaged material away from these features. - The embodiments illustrated in FIGS. 2 and 3 are also employable in
bag 44 and function in manner similar to the embodiment shown in FIGS. 1, 6 and 7 to deflect a packaged material away frommale rib 28 andfemale groove 22. For example, FIGS. 8 and 9 illustrate abag 44″ employing thezipper 10″ shown in FIG. 3. Unlike the embodiment shown in FIGS. 1, 6 and 7, nofill tube 52 is required to insert the packagedmaterial 48″ intobag 44″. Instead, as shown in FIG. 8,protective flanges material 48″ away frommale rib 28″ andfemale groove 22″. Thus, asbag 44″ is filled, none of the packagedmaterial 48″ comes into contact withmale rib 28″ orfemale groove 22″, allowingzipper 10″ to be closed without interference. - When
bag 44″ is emptied, as shown in FIG. 9,protective flange 32C and the longerfemale hook 18″ deflect the packagedmaterial 48″ away frommale rib 28″ andfemale groove 22″. Thus, as bag is emptied, none of the packagedmaterial 48″ becomes attached to or clogsmale rib 28″ orfemale groove 22″, allowingzipper 10″ to be re-closed without interference. - Although certain preferred embodiments of the present invention have been described, the invention is not limited to the illustrations described and shown herein, which are deemed to be merely illustrative of the best modes of carrying out the invention. A person of ordinary skill in the art will realize that certain modifications and variations will come within the teachings of this invention and that such variations and modifications are within its spirit and the scope as defined by the claims.
