Definitions

  • the present invention relates to a container lid, and more particularly to a lid for a cosmetic container.
  • a cosmetic container should fulfill some requirements. It should look spectacular to increase its commercial value. It is preferable to have a lighter weight and a lower manufacturing cost.
  • a metallic container has a good appearance but is relatively heavy and costly. More importantly, when a metallic material is used as a packing of a container lid, it greatly degrades air-tightness of the container. Since most of recent cosmetic is volatile, the cosmetic container is required to have sufficient air-tightness. Accordingly, most of recent cosmetic container lid has its external parts made of metallic material and internal parts, especially a packing made of elastic material such as cork or resin material.
  • the container lid is an integral assembly and, therefore, must be disposed in whole after use. When a container lid has two or more of different material parts, its whole disposal would cause an environmental problem.
  • Another object of the present invention is to provide a novel construction of a container lid which is made solely of metallic material but still capable of providing a sufficient degree of air-tightness when fitted onto a container body.
  • a container lid comprising a cylindrical metallic screw member detachably fittable onto a container mouth; a metallic outer cap fitted around the screw member; and a metallic packing member secured above an open top of the screw member and below a closed top of the outer cap, wherein the packing member is elastically deformable, when the lid is fitted onto the container mouth, to air-tightly seal the container mouth.
  • the packing member has an internal closed air chamber which is deformable when the lid is fitted onto the container mouth.
  • the packing member has a substantially flat lower skin to be placed on the container mouth, a convexed upper skin and an internal closed air chamber formed between the flat lower skin and the convexed upper skin.
  • the packing member has a convexed lower skin to be placed on the container mouth, a substantially flat upper skin and an internal closed air chamber formed between the convexed lower skin and the flat upper skin.
  • the packing member has convexed upper and lower skins and an internal closed air chamber formed between the convexed upper and lower skins. In each of these embodiments, the air chamber is deformable when the lid is fitted onto the container mouth.
  • a press member may be positioned between the packing member and the closed top of the outer cap.
  • the packing member may have a substantially flat plate with an upstanding rim flange fitted within and below the outer cap.
  • a closed air chamber is formed between the packing member and the closed top of the outer cap.
  • the packing member may comprise a hat-like member having a substantially flat peripheral area, with an upstanding rim flange fitted within and below the outer cap, and a convexed crown deformable when the lid is fitted onto the container mouth.
  • the upstanding rim flange is engaged within a cylindrical wall of the outer cap and the crown is in contact with the closed top of the outer cap.
  • the underside of the packing member is covered with a resin layer.
  • the resin layer may be formed by a resin coating, a laminated resin film, or a layer of an oxide of a base metal material of the packing member.
  • the underside of the packing member is covered with an aluminum foil.
  • Fig. 1 illustrates a container lid embodying the present invention.
  • the container lid shown in Fig. 1 comprises a screw member 1, a hollow packing member 7 and an outer cap 13.
  • Screw member 1 is detachably fitted around a threaded wall 3a of a container mouth 3.
  • Outer cap 13 is fitted around screw member 1. More particularly, a lower portion 13a of outer cap 13 tightly overlaps a corresponding lower portion 1a of screw member 1. Further, the lower end of screw member 1 is rounded to the outside upwardly to form an annular groove, into which the lower end of outer cap 13 is inserted and fastened.
  • packing member 7 is fitted below a closed top of outer cap 13 and above an open top 5 of screw member 1.
  • packing member 7 of this embodiment comprises a pair of oppositely swelling or convexed skins 7a, 7b which are air-tightly connected with each other at rim portions thereof to provide an internal closed air chamber 10.
  • a rim portion 11 of lower skin 7b is folded to clamp a flat rim portion of upper skin 7a.
  • Packing member 7 is deformably press-fit positioned between the closed top of outer cap 13 and the open top of screw member 1 when the lid is fitted onto container mouth 3.
  • packing member 7 is depressed and deformed between the closed top of outer cap 13 and the open top of screw member 1 when the container is lidded.
  • the internal closed air chamber 10 of packing member 7 will act as an air spring and facilitate air-tight sealing of container mouth 3, which prevents deterioration and degeneration of contents such as cosmetic in the container for a longer period of time.
  • a spring force stored in packing member 7 is readily released and, accordingly, packing member 7 is returned to its original shape.
  • Screw member 1 and outer cap 13 are both made of aluminum.
  • Packing member 7 is made of an alloyed aluminum, a typical example of which is referred to by "GM-145" manufactured by Sumitomo Aluminum Co., Ltd, having compositions and mechanical characteristics shown in the following Tables I and II.
  • Fig. 2 illustrate another embodiment of the present invention.
  • a press member 15 is interposed between a closed top of outer cap 13 and a packing member 7.
  • packing member 7 of this embodiment comprises a flat upper skin 7a and a swelling lower skin 7b to form therebetween an internal closed air chamber 10.
  • a rim portion of upper skin 7a is folded to clamp a flat rim portion of lower skin 7b.
  • Press member 15 includes a flat bottom 15a in contact with packing member 7 and an upstanding flange 15b fitted below the closed top and within the cylindrical wall of outer cap 13 so that there is another air chamber 16 between the closed top of outer cap 13 and flat bottom 15a of press member 15.
  • Internal closed chamber 10 of packing member 7 cooperates with press member 15 to provide a sufficient air-tight sealing against the open top of mouth 3 when the container is capped.
  • Press member 15 is also deformable and adjusts a degree of deformation of packing member 7.
  • FIG. 3 illustrates still another embodiment of the present invention.
  • a packing member 7 of this embodiment does not have a hollow structure, but has a substantially flat bottom 12 surrounding a convexed central area 7c, with an upstanding flange 7d, as shown in Figs. 6A to 6C, thereby providing a closed chamber 8 below a closed top of an outer cap 13.
  • convexed central area 7c of packing member 7 is depressed and deformed within chamber 8.
  • Such deformation of packing member 7 will act as a leaf spring and facilitate air-tight sealing of container mouth 3, thereby effectively preventing deterioration and degeneration of contents such as cosmetic in the container.
  • Screw member 1 of this embodiment has somewhat different shape than in the preceding embodiments, which comprises an inner screw wall engageable with container mouth 3a, an outer wall 1a fitted within a wall of outer cap 13 and having an abutment 1b with the lower end of outer cap 13, and a horizontal top surface 5 connecting the upper ends of the inner screw wall and the outer wall. Horizontal top surface 5 will stably support thereon a bottom 12 of packing member 7 when the container is capped. This is merely a variation regarding a shape of screw member 1.
  • FIGs. 7 to 10 show various modifications of hollow packing members 7.
  • a packing member 7 shown in Figs. 7A to 7C provides an internal closed air chamber 10 between a flat upper skin 7a and a swelling or convexed lower skin 7b.
  • a rim portion of lower skin 7b is folded to overlap a rim portion of upper skin 7a.
  • a packing member shown in Figs. 8A to 8C has an upside-down structure of that of Figs. 5A to 5C, which comprises a swelling upper skin 7a and a flat lower skin 7b to form therebetween an internal closed air chamber 10.
  • a rim portion of lower skin 7b is folded to clamp a flat rim portion of upper skin 7a.
  • Figs. 9 and 10 show modification of packing member 7 of Figs. 4A to 4C.
  • both of upper and lower skins 7a and 7b have center swellings which cooperate with each other to define therebetween an internal closed air chamber 10.
  • lower packing element 7b has a flat peripheral area 11 with an inwardly upstanding flange 11a engaging a flat face of upper skin 7a.
  • both of upper and lower skins 7a and 7b have overlying upstanding flanges 11a.
  • packing member 7 may have a multi-layer construction.
  • the uppermost layer 7e is made of an alloyed aluminum having compositions and mechanical properties shown in Tables I and II, which is back-coated with a couple of aluminum foils 7g, 7g via adhesive layers 7f, 7f, respectively.
  • a single or any number of aluminum foils 7g may be adhered to the underside of uppermost layer 7e.
  • the container lid of the present invention is particularly used in combination of a container for cosmetic, for example.
  • Cosmetic contained in the container will contact with the underside of packing member 7 every time when the lidded container is tilted inverted and shook. Therefore, packing member 7 preferably has, at its bottom, a resin layer 9 which prevents deterioration and degeneration of cosmetic in the container.
  • Resin layer 9 may preferably be made of PET (polyethylene terephthalate) or PP (polypropylene).
  • resin layer 9 is different in material than other components, that is screw member 1, outer cap 13 and packing member 7 which are all made of metallic material, such resin material of bottom layer 9 is very thin and, therefore, combustible during metallic material processing (re-dissolution of aluminum, for example).
  • the container lid of this invention is an integral, unseparatable assembly but can be disposed in whole.
  • Metallic material of the container lid is easily processed after disposal and reusable. Its whole disposal will not at all cause an environmental problem.
  • Bottom layer 9 may be made by coating, film lamination or any other suitable method.
  • Figs. 12 to 27 show various embodiments of the present invention which include packing member 7 with a bottom resin layer 9.
  • the container lid of Fig. 12A employs a dish-like packing member 7 having a substantially horizontal bottom 12 with an upstanding peripheral flange 11 fitted air-tightly below the closed top and within the cylindrical wall of an outer cap 13, so that there is provided an internal closed space 8 therebetween.
  • packing member 7 is depressed and deformed within space 8 when the container is lidded due to engagement between screw member 1 and threaded wall 3a of container mouth 3, as shown in Fig. 12B.
  • packing member 7 will act as a leaf spring and facilitate air-tight sealing of container mouth 3, which prevents deterioration and degeneration of cosmetic in the container for a longer period of time.
  • a spring force stored in packing member 7 is readily released and, accordingly, packing member 7 is returned to its original shape.
  • packing member 7 has a back resin coating 9.
  • Packing member 7 may have another dish-like shape, as shown in Fig. 14 and Fig. 15. In either embodiment, packing member 7 has no flange and simply comprises a round concaved bottom 12. The embodiment of Fig. 15 has more gently-sloping concaved bottom 12 than in the embodiment of Fig. 14.
  • FIGs. 16 and 17 illustrate a modified embodiment of the present invention.
  • a hat-like packing member 7 used in this embodiment resembles one shown in Figs. 6A-6C but has a bottom resin layer 9.
  • convexed central area 7c of packing member 7 is depressed and deformed within chamber 8, as shown in Fig. 16B.
  • Such deformation of packing member 7 will act as a leaf spring and facilitate air-tight sealing of container mouth 3, thereby effectively preventing deterioration and degeneration of cosmetic in the container.
  • packing member 7 is returned to its original shape.
  • Packing member 7 of Figs. 6A-6C may be modified as shown in Figs. 18A-18C which has no flange.
  • FIGs. 19 and 20 illustrate still another embodiment of the present invention.
  • a packing member 7 in this embodiment has a layered construction comprising upper and lower skins 7a and 7b.
  • Upper skin 7a is similar to packing member 7 shown in Figs. 6A-6C, having a convexed central portion 7c surrounded by an unflanged flat peripheral face.
  • Lower skin 7b has a flat bottom 12 with an upstanding flange 11 that engages a rim of the flat peripheral face of upper skin 7a, whereby upper skin 7a is fixedly supported and superposed on bottom 12 of lower skin 7b.
  • an internal closed air chamber 10 is defined between convexed central portion 7c of upper skin 7a and flat bottom 12 of lower skin 7b.
  • Upper skin 7a is made of aluminum.
  • Lower skin 7b is also made of aluminum, but a resin layer 9 is formed onto its underside.
  • Packing members 7 shown in Figs. 21, 22, 23A-23C, 24A-24C and 25A-25C are substantially the same as those shown in Figs. 9, 10, 4A-4C, 8A-8C and 7A-7C respectively, but have a bottom resin layer 9.
  • FIG. 26 An embodiment shown in Fig. 26 has substantially the same construction as that of Fig. 2.
  • This embodiment employs a packing member 7 shown in Fig. 27A-27C which resembles that of Figs. 5A-5C but a lower swelling skin 7b has a bottom resin layer 9.
  • a press member 15 is interposed between a closed top of outer cap 13 and a packing member 7.
  • this construction will provide double air-spring function and improve air-tight sealing capability of the container lid.
  • Test samples No.1-1 to 1-4 are examples of the present invention. More specifically, Sample No. 1-1 was prepared as an example of the embodiment shown in Fig. 1 employing a hollow packing member 7 of Figs. 4A-4C. Sample No. 1-2 was prepared as an example of the embodiment shown in Figs. 12 and 13 in which a flanged packing member 7 has a bottom resin layer 9 by coating. Sample No. 1-3 was substantially identical to Sample No. 1-2 but the bottom resin layer was formed by film lamination. Sample No. 1-4 was substantially identical to Sample No. 1-1 but a packing member 7 was a multi-layered one as shown in Fig.
  • Sample No. 2 uses a simple flat aluminum plate as a packing member
  • Sample No. 3 uses a polypropylene sheet packing
  • Sample No. 4 uses a cork packing.

  • a competent packing must have a sealing property that a reduction of contents is lower than 0.2%.
  • the test results shown in Table III prove that the samples of the present invention (Sample Nos. 1-1 to 1-4) greatly exceed this requirement and may be used as excellent packing members.
  • the sealing properties of these samples are equivalent to or still better than that of Sample No. 3 (polyethylene) which has been recognized as most preferable packing material.
  • Sample No. 2 could not satisfy the above-described sealing requirement.
  • Sample No. 4 showed an extraordinarily high reduction rate because a considerable amount of the contents leaked out through a porous cork packing.
  • the container lid in the preceding embodiments may be used for a container of any material such as glass and plastic.
  • Figs. 28 and 29 respectively show modifications of the embodiment shown in Fig. 3 which has an internal closed chamber 8 defined between a packing member 7 and an outer cap 13.
  • packing member 7 in Figs. 28, 29 has a different shape rather than that of the embodiment of Fig. 3. More particularly, packing member 7 in Fig. 28 has a concaved bottom 12 with an inwardly downward slope surface 12a which provides a sealing contact with a container mouth 3 when the container is capped. In this embodiment, a slight contact between slope surface 12a and container mouth 3 will be enough to provide a sufficient degree of air-tightness of the container.
  • a packing member 7 is fitted above an open top of a screw member 1 and below a closed top of an outer cap 13. However, as shown in Figs. 30-35, it can be fitted above a container mouth 3 and below a screw member 1.
  • a dish-like packing member 7 has a horizontal flange 11 fitted beneath a horizontal top 5 of a screw member 1, and a horizontal bottom 12 fitted above a container mouth 3, thereby providing a hollow chamber 8 between top 5 of screw member 1 and packing member 7.
  • packing member 7 is depressed and deformed in a direction A, and then tends to be returned to its original shape in the opposite direction B, which provides a sealing contact with container mouth 3.
  • Figs. 31A and 31B show a modification of the embodiment of Fig. 30, in which a packing member 7 is fitted in a different way.
  • the upper portion of the cylindrical wall of a screw member 1 has a plurality of spaced, inwardly projecting ridges 5a that engage with a plurality of recesses 11b formed at a horizontal flange portion 11 of packing member 7.
  • a packing member 7 has an upstanding rim 11 that is press-fit within the upper cylindrical wall 5b of a screw member 1.
  • a packing member 7 has a folded round rim 11 that is press-fit within the upper cylindrical wall 5b of the screw member 1.
  • a packing member 7 in Fig. 34 has a closed top 71 in abutment with the top 5 of a screw member 1 and an enlarged bottom opening. The lower end of an enlarged bottom 72 comes into contact with the top of a container mouth 3 when the container is capped.
  • Fig. 32 may be modified as shown in Fig. 35 in which a spacer 18 is interposed between an outer cylindrical wall of a screw member 1 and an inner cylindrical wall of an outer cap 13.
  • outer cap 13 may have an apparent diameter substantially identical to the container 20.
  • the embodiments shown in Figs. 30-35 are particularly useful when the container is made of glass.
  • a packing member 7 is also positioned between a screw member 1 and a container mouth 3, but is normally smaller than the outer cylindrical wall of screw member 1 to provide a gap G therebetween (see Fig. 36A).
  • This embodiment is also particularly advantageous when used in combination with a glass container. When the container lid of this embodiment is too much tightly fastened onto container mouth 3, packing member 7 could be deformed outwardly within the gap G (see Fig. 36B) so that container mouth 3 would not be given an excessive force and thus prevented from damage.
  • a packing member 7 is normally smaller than the outer cylindrical wall of screw member 1 and has an annular concaved portion for air-tight contact with a container mouth 3, as in the embodiment of Figs. 36A and 36B.
  • a top 5 of screw member 1 has an annular convexed portion 5c positioned above the annular concaved portion of packing member 7 to define a hollow chamber 8 therebetween.
  • Chamber 8 acts as an air cushion to prevent container mouth 3 from excessive depression.
  • a packing member 7 normally smaller than the outer cylindrical wall of a screw member 1 has a central swell 7c that is engaged within a center hole 5d of a top 5 of screw member 1.
  • there is another gap G between swell 7c and hole 5d which cooperates with gap G to allow a greater extent of deformation of packing member 7 and prevent more effectively damage of container mouth 3 when the container 20 is capped with an excessive force.
  • Packing member 7 may have a flange 11 entirely or partly at a peripheral portion thereof. It may be upstanding (as in Figs. 36A and 36B) or horizontal (as in Figs. 37A and 37B).
  • the packing member is preferably made of aluminum but may be of another metallic material.
  • the packing member may have a flange of any desired shape, and may have no flange as shown in Figs. 7, 11, 14, 15, 18 and 25.
  • An internal closed air chamber must be defined within or above the packing member but its shape is not limitative.
  • the metallic packing member preferably have a resin layer that is formed by coating or film lamination on its underside, in order to prevent deterioration and degeneration of the contents, particularly cosmetic in the container.
  • PET or PP is a favorable material to be used as such resin layer, but another suitable resin material may be used.
  • an aluminum oxide coating may be formed on the underside of the metallic packing member by anodization.
