Definitions

  • ABSTRACT Application Priority Data Cover construction for an eating bowl.
  • a cover for an 2227472 eating bowl is made from thin aluminum provides with corrguations arranged parallel to each other and ori- /5 220/72, 2 9/35 ented in both the longitudinal direction of the bowl 229/43 B65d 5/72, B65d 17/24 220/72; 229/51 TS, 51 D and transversely thereto.
  • the longitudinal corrugations are somewhat deeper than are the transverse corrugations.
  • An opening tab is preferably provided at one longitudinal end of the cover to initiate opening of the bowl by tearing of said cover.
  • a major objective of the invention is to develop a cover of the type mentioned above which can be made as cheaply as possible and which can be torn open easily and without danger of soiling. This is accomplished in accordance with the invention in that the cover material is designed with corrugations extending in spaced parallel relation, both in the direction of tearing and transversely thereto.
  • the cover has increased stability due to the corrugations which extend in spaced parallel relation both in the direction of tearing and also transversely thereto so that the cover material can be thinner than the container material with resulting economy.
  • the corrugations which optically appear as a patterned area of the cover do not reveal fingerprints on the cover surface, or do so only with difficulty, so that a substantially more esthetic appearance of the closed container is ensured as compared to known covers which have shining smooth surfaces which emphasizes finger marks. It is also important that there is no reduction in the strength of the cover foil which is the case when lines for tearing are scratched or perforated into the cover.
  • the corrugations are designed with a width corresponding to a multiple of the cover thickness, such as, usually, a width at least ten times the cover thickness. This prevents overstressing of the cover material when the corrugations are applied while fully maintaining the advantages described above.
  • FIG. 1 is an oblique schematic illustration of a container having a cover of the type above described
  • FIG. 2 is a schematic plan elevation of the cover in accordance with FIG. 1;
  • FIG. 3 is a sectional elevation through the cover in accordance with FIGS. 1 and 2.
  • the drawing shows a container, for example an eating bowl 1, of aluminum foil which is closed by a cover 2 which has an opening tab subdivided by cuts to form sections 2a, 2b, 2c.
  • Corrugations 2d, 2e are provided, preferably parallel with each other, in the material of the cover 2 both extending in spaced relation in the direction of tearing (i.e., perpendicularly to the side on which theopening tab is located) as well as transversely thereto.
  • the corrugations have a width which cor responds to a multiple of the thickness of the cover material.
  • This is also preferably of aluminum foil which, however, can be selected to be somewhat thinner than the container material at least in the region of the corrugations due to the reinforcement effected by the corrugations.
  • the corrugations have a width of 1 mm. and the foil has a thickness of 1/10 mm.
  • the invention is not limited to the embodiment shown in the drawing, particularly with reference to the number and/or width of the corrugations.
  • the container can also be designed with a base outline differing from the one shown in the drawing, for example round or with more or less than four corners.
  • a cover of flexible foil material usable for covering the top of a container, particularly an eating how]
  • such cover being provided adjacent one side of the container with an opening tab movable away from the container for tearing away a portion of the cover to allow access to the contents of the container, the improvment comprising:
  • said cover portion means for causing said cover portion to bend slightly at spaced locations therealong during removal, so as to prevent a springlike rolling up of the cover portion upon removal from the container, and consisting of a plurality of second corrugations arranged in spaced parallel relation at said locations over said major area of the cover and extending transversely across said first corrugations.
  • a cover according to claim 2 in which the longitudinal dimension of said cover exceeds the transverse dimension thereof, said first corrugations extending longitudinally of the cover, said second corrugations extending transversely of the cover, said tab being provided at one longitudinal end of said cover.
