Definitions

  • the present invention relates to reclosable plastic bags with slider zippers and tamper evidence.
  • the Herrington U.S. Patent 5,007,143 shows a zipper profile which is opened and closed by a slider that is grasped by the user for opening and closing the bag. It is desirable in certain situations to provide tamper evidence to the user of a reclosable bag.
  • the Hustad et al. U.S. Patent 5,456,928 is an example of a patent disclosing a reclosable bag for use with food products which has tamper evident means incorporated therein. There are certain situations, for example, where a slider zipper reclosable bag is used to contain a product that is being marketed and it is also desirable to provide tamper evidence.
  • One embodiment of the invention might include a plastic film bag having a pair of side walls which are secured to one another and define a mouth of the bag.
  • a reclosable fastener extending along the mouth of the bag and secured to the side walls.
  • the fastener includes a pair of flexible fastening strips secured to the side walls and including reclosable interlocking rib and groove profile elements on the respective strips.
  • a slider straddles the fastener for opening and closing the fastener.
  • the slider includes a depending separator extending between the flexible plastic strips.
  • a sheet of plastic film closing the mouth of the bag which sheet is capable of rupture to provide access and tamper evidence.
  • FIG. 1 is front elevational view of a reclosable plastic bag including the tamper evident zipper slider of the present invention.
  • FIG. 2 is a fragmentary perspective view of a portion of the structure of FIG. 1.
  • FIG. 3 is a vertical section taken along the line 3-3 of FIG. 2 in the direction of the arrows.
  • FIG. 4 is a vertical section taken along the line 4-4 of FIG. 2 in the direction of the arrows.
  • FIG. 5 is a bottom plan view of the slider of the present invention.
  • FIG. 6 is a section taken along the line 6-6 of FIG. 5 in the direction of the arrows.
  • FIG. 7 is a vertical section similar to FIG. 3 of an alternative embodiment of the present invention.
  • FIG. 7A is a front elevation similar to FIG. 1 of the alternative embodiment of the present invention.
  • FIG. 8 is a vertical section taken through the zipper slider and the bag of FIG. 1.
  • FIG. 9 is an enlarged fragmentary view similar to FIG. 8
  • FIG. 10 is a view similar to FIG. 8 of an alternative embodiment of the present invention.
  • a plastic bag 11 which consists of a pair of side walls 12 and 13 which are connected together at the bottom and at the sideward edges 16 and 17 of the bag.
  • the connection at the bottom 15 may be merely by folding a single sheet of plastic to produce the two side walls 12 and 13 or may be by actual melting and cutting or adhering the two side walls together by adhesive.
  • the side edges 16 and 17 are frequently formed by melting the two side walls together and then by cutting apart from the adjacent side walls of further bags being produced.
  • the two side walls 12 and 13 define a mouth 20 of the bag along which a reclosable fastener 21 extends.
  • the fastener includes a pair of flexible plastic strips 22 and
  • the reclosable fastener further includes a flange 32 which functions to close over the top of the fastener when it is in closed position.
  • a slider 35 is arranged to straddle the fastener 21 for opening and closing the fastener.
  • the slider 35 has a fixed separator member 36 which extends down between the profile elements 26 and 30 for the purpose of separating them and opening the fastener when the slider is moved rightwardly as viewed in FIG. 2.
  • FIG. 3 shows the slider section taken along the line 3-3 of FIG. 2 and shows the profile elements in open condition.
  • the slider When the slider is moved leftwardly as viewed in FIG. 2 the slider functions to close the profile elements and to connect them as shown in FIG. 4. The connection occurs by reason of the walls 37 of the slider squeezing the profile elements together.
  • the slider is retained on the fastener elements by shoulders 40 and 41 which are also formed on the fastener elements.
  • the slider has inwardly projecting flanges 38 which engage the shoulders 40 and 41 to retain the slider on the fastener.
  • the reclosable fastener has formed homogenously and coextensively therewith a sheet of plastic 40'.
  • This sheet of plastic 40' may be extruded along with the fastener elements 22 and 25 but has a somewhat less thick construction than the strips 22 and 25 and particularly the web portion thereof 41 and 42.
  • i is intended that the present bag be used frequently in situations where the bag is filled at the factory with a product and then is marketed to the consumer. The consumer then buys the bag and is reassured that it has not been tampered with because the closure 40 is in place and needs to be ruptured before the consumer can use the contents of the bag. If the consumer does not wholly consume the contents he can then reclose the bag and use it further to contain the partially filled bag.
  • FIG. 10 An alternative embodiment of the reclosable fastener of FIG. 8 is shown in FIG. 10 and involves a tamper evidence closure 50 that extends between the walls or webs 41' and 42' of the reclosable fastener elements 22' and 25'.
  • the construction of FIG. 10 is extruded in a similar fashion to the construction of FIG. 8.
  • FIGS. 7 and 7A Still another alternative embodiment of the invention is illustrated in FIGS. 7 and 7A.
  • the reclosable closure and slider are identical to those above described except that the sheet 40 is eliminated.
  • the tamper evident slider bag of FIG. 7 has a sheet 60 which forms a hood that covers and surrounds the reclosable closure 70 and the slider 71 of the bag of FIGS. 7 and 7A.
  • the embodiment of FIG. 7 will be provided with perforations 72 which facilitate removing the tamper evident sheet 60. If desired perforations may also be provided in the embodiment of FIG. 8 such as for example at the location 61.
