Definitions
- This invention relates to lids and it is more particularly concerned with the construction of lids adapted to fit conventional containers commercially used to hold products, such as ice cream, cottage cheese, sour cream, and solids and liquids generally of various kinds.
- An object of the invention is the provision of a lid which is functionally identical to conventional types of lids, but which is simpler in construction and easier to manufacture than the conventional types.
- Another object is the provision of such a lid which requires substantially less material to construct, thereby effecting a saving in the material, but without sacrificing functional requirements.
- FIGS. 1 and 1a are top plan views, respectively, of a conventional form of lid and an embodiment of the present invention.
- FIGS. 2 and 2a are bottom plan views of the same lids, respectively, of FIGS. 1 and 1a.
- FIGS. 3 and 3a are side elevational views of the same lids.
- FIGS. 4 and 4a are vertical sectional views along the line 44 and 4a4a of FIGS. 1 and 1a, respectively, on an enlarged scale, partly broken away, and arranged in side by side relation on the sheet to illustrate the dilferences clearly.
- Conventional lids of the type illustrated in FIGS. 1, 2, 3 and 4 comprises a tube 11 of stiif cardboard.
- Patented Oct. 10, 1967 end of the tube contains a disc 12 having an annular flange 13 disposed in an annular pocket 14 formed by a reversely curved skirt portion 15 at one end of the tube.
- the flange 13 is usually secured to the skirt portion 15 by crimping with means well known to the art.
- Such means comprise machinery which is expensive to construct and operate.
- This type of lid is also wasteful of material due to different factors hereinafter explained.
- the lid can easily and less expensively be made by eliminating the flange 13, eliminating a substantial portion of the skirt 15, leaving only enough to form a bead 16, and then sealing the marginal edge of a disc 17 to the bottom of the bead by means of a suitable material, such as an adhesive resin 18.
- a suitable material such as an adhesive resin 18.
- Polyethylene resin has been found suitable for this purpose. It is a thermosetting resin, can be applied in a liquid form, and then hardened by the application of heat, such as by a hot iron (not shown), a procedure well known in the art.
- Polyvinyl acetate is also suitable for use in the same way.
- the resulting lid has an inside depth equal to that of the conventional lid, yet less material is used. Compare FIG. 4 with 40 and 3 with 3a.
- the seal between the disc and the bead is even more effective than the seal formed by the crimping of overlapped portions of conventional lids.
- portions of the conventional type of lid comprise the parts a, b and c which total about 25% of the material of which the lid is made and which is saved by the present construction. This is substantial in a field where the cost of production is an important factor and the materials used are relatively expensive to make, transport and store.
- a lid construction comprising a tubular member having an annular wall, a rim bead at one end and a disc secured to the bead, the improvement consisting of restricting the bead to a form in which an outer marginal edge is folded completely under an adjacent portion of the bead at right angles to the wall of the tubular member, said disc being restricted to a flat flangeless form, said disc being attached at its marginal edge to the said outer marginal edge of the head with an adhesive material, thereby reducing the amount of materials of which the lid is made and reducing also the overall height of the lid while retaining all of its essential functional characteristics.
