    At the left side of the card 224′ (as seen in FIG. 19) is a tab 232′ which is intended to fit within slot 236′ of the first card 226.
  • [0077]
    In assembling the blister package 210, the plastic blister 212 is laid down in an appropriate station in a blister sealing machine. The products to be sealed within the package are then inserted into the pockets 214, 214′, 214″. After the products are in the pockets, the first card 226 is aligned with the protrusions 221 and is sealed to the flange 222 of the plastic blister 212 in a substantially permanent manner, either by adhesive or heat sealing. Then, the second card 224 is placed within the rim 219 such that the recesses 228 are in alignment with the protrusions 218. The tab 232 of the second card 224 rests on top of the slot 236. The left portion 242 of the second card 224 is substantially permanently sealed to the planar portion 217 of the plastic blister 212. In addition, the peripheral portions of the remaining portion of the second card 224 are lightly or spot sealed along the peripheral flange 222 of the plastic blister 212. If desired, the right edge of the second card 224 can be lightly sealed to the top of the first card 226, although such sealing is not necessary.
  • [0078]
    Then, the third card 224′ is placed within the rim 219 such that the recesses 228′ are in alignment with the protrusions 220. The tab 232′ of the third card 224′ rests on top of the slot 236′. The right portion 242′ of the third card 224′ is substantially permanently sealed to the flange 222 of the plastic blister 212. In addition, the peripheral portions of the remaining portion of the third card 224′ are lightly or spot sealed along the peripheral flange 222 of the plastic blister 212. If desired, the left edge of the second card 224′ can be lightly sealed to the top of the first card 226, although such sealing is not necessary.
  • [0079]
    Alternatively, the cards 224, 224′, and 226 can be sealed simultaneously to the blister 210 after the cards 224, 224′, and 226 have been placed on the blister. In either case, the cards 224, 224′, and 226 are sealed to the blister 210 by adhesive or heat sealing, or any suitable method known to those of ordinary skill in the art. The method by which the cards 224, 224′, and 226 are sealed to the plastic blister 210 is intended to be substantially permanent.
  • [0080]
    To remove the products from the pocket 214, the right side 243 of the second card 224 is lifted up from the first card 226 and from the plastic blister 212. This lifting process causes the second card 224 to fold along the fold line 234. After the products have been removed from or inserted into the pocket 214, the tab 232 is then tucked into the slot 236 to hold the second card 224 in place on top of the first card 226 and the plastic blister 212.
  • [0081]
    To remove the products from the pocket 214″, the left side 243′ of the third card 224′ is lifted up from the first card 226 and from the plastic blister 212. This lifting process causes the third card 224′ to fold along the fold line 234′. After the products have been removed from or inserted into the pocket 214″, the tab 232′ is then tucked into the slot 236′ to hold the third card 224′ in place on top of the first card 226 and the plastic blister 212.
  • [0082]
    To remove the products from the pocket 214′, the first card 226 is simply removed from the plastic blister 212. The first card 226 is not designed to be resealed on the plastic blister 212 in this illustrated embodiment.
  • [0083]
    A fourth embodiment of the present invention is illustrated in FIGS. 20-23. The fourth embodiment relates to a plastic package 300 that is particularly adapted for holding batteries. However, the package is suitable for numerous other products, as well.
  • [0084]
    The package 300 includes a lower half 312 that is made from PVC or PET material. For purpose of stability, ridges 314 may be formed in the sidewalls of the lower half to reinforce the sidewalls. See FIG. 21.
  • [0085]
    FIG. 23 is a plan view of the lower half 312. As best seen in FIG. 23, a flange 316 extends around the outer periphery of the top of the lower half 312. At one edge of the flange 316 is a perforated line 318 made to facilitate separating the outer edge 319 from remainder of the lower half 312.
  • [0086]
    In addition, tabs 320 are formed near the top of the walls, adjacent the flange 316.
  • [0087]
    A top plan view of the lid 324 is illustrated in FIG. 22. The lid also includes a flange 334 adapted to fit against the flange 316 of the lower half 312 of the package 300. The lid 324 also includes a hinge 330 or fold line dividing the lid 324 into a first, fixed half 326 and a second, hinged half 328. The flange 334 extending around the fixed half 326 of the lid 324 is permanently sealed to the respective portion of the flange 316 of the lower half 312 by a heat sealing or adhesive process.
  • [0088]
    In addition, the portion of the outer flange 334 of the lid 324 that is facing the outer flange 319 of the lower half 312 is secured to the outer portion 319 of the flange 316 of the lower half 312. In a preferred embodiment, the remainder of the outer flange 334 of the second, hinged half 328 is not sealed or secured in any way to the flange 316 of the lower half 312. However, in an alternative embodiment, portions of the outer flange 334 of the hinged half 328 may be lightly or periodically sealed to the flange 316 of the lower half 312.
  • [0089]
    To assemble the package 300, the products, such as batteries, that are to be stored in the package 300 are placed in the lower half 312, together with any insert cards or additional material. The lid 324 is then placed on top of the lower half 312, and is then sealed, as described above.
  • [0090]
    To access the contents of the package 300, the outer flange 316 of the lower half 312 is separated along the perforated line 318 which separates the outer portion of the flange 319 from the remainder of the flange. The outer portion 319 of the flange remains sealed to the outer flange 334 of the second, hinged half 328, thus enabling the second, hinged half 328 to fold along the hinge 330 to provide access to the container 300.
  • [0091]
    The container 300 can be resealed by closing the second, hinged half 328 onto the lower half 312 and locking tabs 320 of the lower half 312 into recesses 332 provided in the lid 324. Thus, the hinged half 328 can be opened and closed as needed by engaging or disengaging the tabs 320 from the recesses 332.
  • [0092]
    As will be appreciated by one of ordinary skill in the art, the lid may be formed in alternative manners, such as the hinge or fold line extending across the short dimension of the package, instead of along the long dimension of the package. In addition, tabs may be formed on the lid with recesses provided in the lower half 312.
  • [0093]
    Although only preferred embodiments are specifically illustrated and described herein, it will be appreciated that many modifications and variations of the present invention are possible in light of the above teachings and within the purview of the appended claims without departing from the spirit and intended scope of the invention.
