  • FIG. 20 is a view of the package of FIG. III with the cover removed.
  • a package 2 in accordance with the invention has a hollow body 4 with a reduced portion 6 which is adapted to telescope with a cover 8. Portion 6 tapers inwardly in the direction of cover 8.
  • the open end of cover 8 has a peripheral in wardly extending lip III which is adapted to engage groove I2 in body 4 at the inner end of portion 6 to releasably hold cover 8 on body 4.
  • Package 2 is shown in FIGS. 3 and 4 with cover 8 still integrally connected to its portion 6.
  • package 2 is comprised of an upper half 16 and lower half I8 having flanges 20 and 22 respectively which are bonded together.
  • Package 2 is cut along the line indicated at 24. It will be appeciated that the package 2 before this cutting is useful in its own right in that a product may be placed inside before flanges 20 and 22 are bonded together.
  • cover portion is sevcred. it can be telescoped over the body it only a portion of the contents of the package are used initially. Lip I0 is deflected as it rides up the taper of portion 6 and snaps into groove I2 to hold the cover in the closed position.
  • FIGS. 5 through 7 An embodiment of the method of this invention is shown schematically in FIGS. 5 through 7.
  • the upper half I6 and the lower half 18 are each formed by taking a sheet 30 of polyethylene and clamping it to a mold 32 having the appropriate configuration and opening 34 leading to a manifold 36 for creating a vacuum.
  • the sheet is heated by a source of heat indicated schematically at 38 and then drawn down into the mold by withdrawing air through manifold 36.
  • the sheet 30 cools against the walls of the mold and is then withdrawn.
  • the upper and lower halves I6 and I8 are then mated with the flanges 20 and 22 being bonded together. for example. by a suitable adhesive or by a high frequency electronic sealing.
  • After the bonding operation if the package is not to be used in the form existing after bonding. it is cut to sever the cover 8 by a cutting device indicated at 42 in FIG. 7 to provide the final package 2 shown in FIG. 8.
  • the method of the invention may vary widely within the parameter of first forming the package with the cover integral with the body portion of the package and then severing the cover. It will be obvious that the method of the invention can be carried out with conventional injection molding and conventional blow molding which are too well known to require further description here and which can be employed to form a package having integral body and cover portions which may then be scv ered to provide a cover telescoping over the body portion.
  • the blow molding and injection molding eliminate the necessity for initially forming upper and lower halves but are none the less more expensive than the thermo forming with a vacuum described more specifically above and which. of course. is also well known in the art.
  • a package 50 shown in FIGS. 9 and II can be employed. for example. for packaging an unusual coin.
  • Package 50 has a cover 52 and a slide 54 with a recess 56 for the receipt of a coin.
  • Grooves 58 and 60 in slide 54 coact with peripheral lip 62 on cover 52 to releasably hold the cover in the fully open position as well as in a retracted position for the display of a coin.
  • the package 50 before the separation of the cover 52 from slide 54 is shown in FIG. and may readily be formed by conventional injection molding with slide 54 and handle end 64 being solid and cover 52 being hol' low. Here again severance along the line 66 separates cover 52 for subsequent telescoping over slide 54.
  • the package 50 can also be made by vacuum forming.
  • a blister package 70 has a vacuum formed upper half72 with a flange 74 bonded to a sheet 76 to provide package 70 with a body 78 having a reduced portion 80 and a cover portion 82.
  • the upper half 72 may be transparent or otherwise. as desired.
  • Reduced portion 80 has a pair of grooves 84 and 86.
  • Cover portion 82 is dimcntioned so that when severance is carried out along the line indicated by the dotted line 88 in groove 86. the cover portion 82 will telescope over the slide portion 80 as shown in FIG. I2 and the cut end of cover portion 82 will engage groove 84 since the cut through groove 86 makes the end have a slightly larger diameter than the main portion of reduced portion 80.
  • FIG. I6 A package 90 having a body portion 92 and a cover portion 94 is illustrated in FIG. I6. Here again severance along line 96 either before or after sale to the consumer provides a cover 94 which can be telescoped over the slide portion 92.
  • a package I02 has a body portion I04 and a top portion I06 respectively having flanges I08 and H0 about an open side (see FIG. I9).
  • Body 104 has a reduced neck portion II2 which in turn has a pair ot'opposcd side flanges I I4 and I I adjacent its open side.
  • a sheet I I6 is secured by an adhesive I I8 to flanges I08 and I but not to flanges H4 and IIS. Sheet II6 which may be made. for example. of paper.
  • synthetic resin or cardboard has a perforated line of weakness indicated at 22 which is centered so as to run over the spaced adjacent ends of flanges I08 and H0 and which is interupted by openings I24 and I26 which respectively span flanges I14 and IIS.
  • thumbnail. knife. or similar instrument is pressed down along line of weakness I22 to sever sheet H6 along this line.
  • the cover I06 with its associated portion of sheet 116 is then removed. If only part of the contents of the package I02 is used. cover I06 can be replaced by telescoping it over neck portion I12.
  • a package comprising a body. and a sever-able cover. a portion of said body being smaller than the cover to permit the telescoping of the cover and body on severance of the cover. said body being formed with an outwardly facing groove. and an inturned lip inte grally connecting said body to said cover for severance of the lip from the body with said cover and removable engagement of the lip into and out of said groove upon said telescoping.
  • a package according to claim I. said body and cover each comprising at least one thermoformed sheet.
  • a package according to claim 2. said body and cover each comprising a backing sheet marginally secured to a respective thermoformed sheet.
  • thermoformcd sheets each comprising a pair of thermoformcd sheets.
  • a package comprising a pair of complementary body sheets secured to each other in facing relation and combining to define a body having an end. at least one of said body sheets having an outwardly facing indent spaced from said body end. a pair of complementary cover sheets secured to ach other in facing relation and combining to define a cover entirely separate from said body and having an interior hollow. said cover sheets having facing marginal portions unsecured to provide an opening communicating between the interior hollow of said cover and the exterior thereof. said opening being of a size for longitudinally sliding telescopic insertion of said body end through said opening. and an inturned projection of one of said cover sheet marginal portions for releasable retaining engagement in said detent.
