A reclosable bag (10) having two external surfaces (22, 24) and a top (20) contains interior seal lock zipper (30) having interlocking elements (32, 34) and at least two exterior guide projections (14) adjacent to and parallel to the interior zipper (30) where the guide projections (14) allow the fingers of the user to be guided across the base of the zipper for simple and easy closure of the bag.

The present invention relates to a resealable plastic bag with external guides parallel to a seal lock zipper means, which guides allow complete reseal of the package.
Reclosable plastic bags or other containers using a “zipper” type reclosable closure are well known in the art and taught, for example, in U.S. Pat. Nos. 4,263,079; 5,070,584 and 5,140,727; Sutrina et al; Dias et al and Kais et al.) There the bag surface adjacent the zipper was shown as smooth. Other patents in this area show interior grip strips above the zipper which strips provide ease of opening the bag and holding it for filling, as taught in U.S. Pat. Nos. 5,009,828 (McCree); and 5,647,100 (Porchia et al.).
What is needed, however, is some means to guide the user's fingers, which may not be dry after loading the bag, to track the zipper for complete reseal, since, in many instances the fingers do not completely track behind the seal lock zipper all the way and several attempts are required for complete closure. It is a main object of this invention to provide a resealable bag containing on the exterior surface near the zipper, a track to insure single time complete closure.
The above needs/objects are met and problems solved by providing a resealable/reclosable bag having two external surfaces, a closed bottom and an open top, an interior seal lock zipper near the top of the bag where the zipper effective to close the bag, and a plurality of exterior guide projections on at least one external surface of the bag adjacent to and parallel to the interior zipper. This allows minimal finger displacement and single time complete closure of the zipper.
Preferably the bag is a thermoplastic material, and the guide projections are on both external surfaces. While in some instances the interior zipper may have a thickened base behind the lock elements of the interior zipper, such as shown in U.S. Pat. Nos. 4,929,487 and 5,211,481 (Tilman et al. and Tilman respectively), that thickened base would not serve or function as a closure guide, just the opposite.
The novel features of the present invention will be better understood by reviewing the following specification together with the accompanying drawings, in which:
Referring now to
A plurality of exterior longitudinally extending guide projections 14 are shown on the external surfaces/walls 22 and 24 of the bag adjacent to and parallel to the interior zipper 30. They extend from side 40 to side 42 of the bag 10, as shown in
The guide projections 14, can be single or multiple outward extensions, for example, two per side are shown in
The guide projection shapes 14, 44 and 46 have one or more outwardly extending external projections of a substantially continuous extension height 50 along their length, outwardly from the bag, shown in
Having described the presently preferred embodiments, it is to be understood that the invention may be otherwise embodied within the scope of the appended claims.
