Definitions

  • This invention relates to bottle closures and more particularly to hood type metal foil bottle caps for dairy bottles.
  • Another object of the invention is to provide a bottle cap of the above character having improved marking thereon in various colors if desired for utilitarian and decorative purposes.
  • a still further object of the invention is the provision of a cap of the above character which has a colored or printed surface of ornamental appearance in which the ornamentation is protected against abrasions, erasures, obliterations, or smearing.
  • Another object of the invention is to provide a hood type bottle cap for dairy 'bottles wherein a barrier is formed when the cap is seated on a bead of a bottle which prevents the liquid contents of the bottle from passing or leaking out around the skirt by capillary action.
  • Yet another object of the invention is the provision in a bottle cap of the above character wherein a part of the cap can readily be folded back to uncover a portion of the mouth of a bottle and which also readily permits the return of the folded back part of the cap to closed position so that the bottle can be recovered.
  • FIG. 1 is an elevational view of a plurality of hood cap-s, embodying my invention arranged in a nested relation;
  • Fig. 2 is an enlarged sectional view taken along the line 2--2 of Figure 1;
  • Fig. 3 is a sectional view of one of the caps in a presealed position on a bottle
  • Fig. 4 is a sectional view similar to Fig. 3 with the cap in a sealed position on the bottle;
  • Fig. 5 is a top view of a bottle cap similar to Fig. 2 embodying a modification of my invention
  • Fig. 6 is a perspective view of the embodiment of Fig. 5 showing a portion of the cap folded 'back into pouring position;
  • Fig. 7 is an enlarged fragmentary sectional view through a portion of a cap wherein a layer of Wax is used as a laminant, and
  • Fig. 8 is a view similar to Fig. 7 wherein the Wax layer is eliminated or reduced in thickness sufficient to serve only as an adhesive.
  • the invention is shown embodied in a bottle closure in the form of a hood type bottle cap of the general type disclosed and claimed in my copending application Serial No. 651,741, tiled March 4, 1946.
  • the cap is formed as a unitary structure and comprises a circular mouth-span ning portion I2 and an annular pleated skirt i3 arranged to flt around the bead I4 of a dairy bottle I5 for sealing the cap to the bottle.
  • the cap is formed as a laminated structure.
  • the layer of metal foil I'I comprises a layer of metal foil I'I, a layer of paper I8, and a layer of plastic materiel such as micro-crystalline wax I9 of appreciable thickness, or other analogous adhesive interposed between the layer of foil I'l and the layer of paper I8.
  • a layer of plastic materiel such as micro-crystalline wax I9 of appreciable thickness, or other analogous adhesive interposed between the layer of foil I'l and the layer of paper I8.
  • the layer of micro-crystalline wax, or the layer of microcrystalline wax and the layer of paper may be omitted. In the latter case, it is evident that the cap will be constructed solely from metal foil.
  • One phase of my invention pertains to the provision of metal foil cap*J having ornamental and informative characters or designs which are neat and attractive in appearance and wherein the characters are protected against smearing, erasing, and the like. Moreover, it is concerned with a cap having such ornamentation that is relatively inexaensive to mamifacture. This is accomplished by providing a cap having an intaglio character or characters 2i impressed or recessed into the outer surface of the mouth-spanning portion I2 of the metal foil cap and having the recessed. or intaglio portions 2
  • the caps there illustrated are formed with a pluraltiy of recessed characters or designs 2I such as shown in Fig. 5.
  • Each of these characters is recessed below the. top surface of the mouth-spanning portion i2 of the cap a suiiicient depth so that when the depressed portion 2i is covered with a layer of ink 22 (see Fig. '7), the upper surface of the layer of ink will be disposed below the unrecessed portions 23 of the mouth-spanning portion I2 of the can.
  • the unrecessed portions or ridges 23 surrounding the depressed characters 2i provide a protection for the inked characters and prevent the latter from becoming smeared or obliterated while the ink is smallest size type (see Figs. and 6) or may bev of larger size and shape substantially equal to the diameter of the mouth-spanning portion I2 of the cap, since the unrecessed portions 23 of the cap will in either case protect the characters.
  • the background surroundingV the design or letters may be recessed and colored if desired.
  • the top 25 (see Fig. 6) of these characters. however. will be in the same plane as the remaining unrecessed portions l23 of the mouthspanning portion I2.
  • An example of both recessipg letters with the background unrecessed and recessing the 'background with the letters unrecessed is shown in Figs. 5 and 6.
  • the letters of the word Grade A at the top of the cap and the letters of the word Pasteurized at the bottom of the cap are recessed and the adjacent surrounding background is unrecessed. Intermediate these words is a rectangular character '2l recessed and forming a background for the letters of the word Milk," these letters being unrecessed.
  • the letters aid in preventing the ink from being smeared in the same manner as the other unrecessed portions 23 of the cap.
  • one phase-of the invention relates to the ink employed toproduce the inked portions.
  • suitable lnk is as follows:
  • the varnish may properly comprise equal parts of China-wood oil and hydrogenated rosin ester.
  • the reducer may be any compatible solvent for reducing the viscosity ofthe ink.
  • the drier may be a conventional cobalt drier containing about three and one-half percent cobalt, and the antioxidant may be any good semi-volatile anti-oxi ⁇ dant. Any ofthe usual materials used in printing inks to improve the llaying and vsharp printing qualities may be used as the compound.
  • composition will vary somewhat for different colors due largely to variance in the oil absorption characteristics ofthe various pigments used in very much the' same manner as the proportions vary in-ordinary linseed oil inks. This variation is largely in the ratio of varnish to pigment. l
  • Another aspect of my invention is directed to fashioning the cap so as to prevent leakage under adverse conditions. ⁇ To this end I provide a depending annular ange 28 between the mouthspanning POrtion I2 andthe pleated skirt I 3,
  • the flange 28 is' formed with a smooth under surface 23 and is arranged to fit smoothly on the upper portion of the bead I4 of the bottle I5 adjacent the mouth 'as shown in Fig. 3.
  • the skirt I3 flares outwardly and downwardly with respect to the flange 28 and forms in effect a continuation thereof.
  • the flange 28 is produced by a mild forming operation and is arranged to'provide a well defined line of demarcation 3I (see Figure 1) between the flange 28 and the skirt I3 andthe creases in the folds of the skirt do not extend beyond the juncture between the flange and the latter member.
  • the indentation 33 is positioned intermediate the bead engaging portions of the cap on opposite sides thereof andv at one side of the diameter .ofthe mouth-spanning vportion of the cap. lPreferably, the slits 34 are aligned with the respective ends of the indentation 33.
  • the portion 32 of the cap may be readily folded back along the indentation33.
  • the smaller portion 32 of the cap should be folded b ack on the larger portion 35 since the larger portion will vbe more securely sealed or held in
  • the indentation 33 forms a hinge about which either portion of the cap may be swung in opening the bottle.
  • the annular flange 28 of the cap will tear. from the ends of the slits 34 up to the mouth-spanning portion I2 on either or both sides of the cap a sufilcient amount to permit the cap to be freely folded back.
  • the bottle can be resealed by simply swinging the portion 32 back over the mouth of the bottle and pressing the skirtportion of the cap'against the bead I4 of the bottle I5.
  • the cap is preferably formed of a laminated structure as shown in detail in Fig. 7, utilizing a layer of paper I8,va layer of thin foil Il, and an intermediate layer of micro-crystalline wax or the like I9, the latter serving as an adhesive to hold the foil and paper together.
  • This layer of Wax serves several As will be seen from Fig. 7, it provides a plastic layer of materia1 which is displaced under the pressure of the type so as to give a better and deeper recession of the printed matter and give a cleaner type impression, and consequently better protection of the ink in service.
  • the layer of wax also assists in producing a better seal between the cap and the bottle, since it will plastically deform under the capping pressure to cause the paper layer to follow and t minor irregularities in the bottle surface.
  • Both the wax and the paper serve the additional function of retarding obliteration of the design in service by acting as a backing to prevent the characters in the relatively thin foil from losing shape due to stretching or other plastic deformation of the relatively ductile metal.
  • the cap may be made from two laminations as shown in Fig. 8, comprising only the paper and foil, using conventional adhesive in only suiiicient quantity to adhere the parts together, and under certain conditions the cap may be formed only from metal foil Without lamination.
  • a partially preformed hood type bottle cap i of laminated form comprising an outer layer of thin metal foil, the outer surface of which is free from ink adherent means, an inner layer of paper, and an intermediate layer oi' moisture-resistant plastic adhesive wax adherent to said inner and outer layers, said -hood being formed with a bottle-mouth-spanning portion and a skirt extending around the periphery of the mouthspanning portion and depending therefrom, said metal foil layer being formed -at the mouthspanning portion with indicia depressed into its outer surface, the metal foil layer; being displaced inwardly at said indicia to form a bottom disposed inwardly of the unrecessed portion of the outer surface of the metal foil layer and inwardly extending side walis, the adhesive wax contiguous with the depressed portion of the metal foil layer being displaced transversely of the inward extent of said indicia to surround the inwardly extending side walls which define said indicia and forming a backing to retain the shape of said indicia, and
  • a partially preformed hood type bottle cap of laminated form comprising an outer layer of thin metal foil, the outer surface of which is free from ink adherent means, an inner layer of paper, and an intermediate layer of plastic micro-crystalline wax co-extensive with and adherent to said inner and outer layers, said hood being formed with a flat, bottle-mouth-spanning portion and a skirt extending around the periphery of the mouthspanning portion and depending therefrom, said metal foil layer being formed at the mouth-spanning portion With indicia depressed into its outer surface, the metal foil layer being displaced inwardly at said indicia to form an inwardly disposed bottom and inwardly extending side walls, the wax contiguous with the indicia formation being plastically deformed and displaced transversely of the inward extent of said indicia to surround the' side walls thereof and forming.
  • a backing to retain the shape of said indicia, and a layer of ink disposed in the -bottom of said indicia and positioned inwardly of the unrecessed portion ofl the outer surface of the mouth-spanning portion of the metal foil layer, the layer of Wax at the skirt of said hood and at the juncture between the skirt and the mouth-spanning portion being plastically deformable under pressure to bear against the contiguous portion of the paper layer and urge the same into close contact with the adjacent bottle surface.
