Definitions

  • the present invention relates to an inner plug of a wide mouth container made of a synthetic resin adapted for being filled with dried powder such as instant coffee or dried powder milk, etc., and particularly pertains to an inner plug put in a mouth of a wide mouthed synthetic resin container and having a function of hermetically closing said mouth part as well as a function for permitting its contents to be discharged.
  • glass containers excellent in anti-oxygen-and-moisture permeability are widely utilized as wide mouthed containers to be filled with dried food powders, but because they are heavy and vulnerable to impact, etc., laminate containers formed of synthetic resin materials excellent in oxygen permeability, including polyethylene terephthalate resin and ethylene vinyl alcohol resin, etc., have been developed in recent years.
  • the aperture formed through the inner plug should desirably be as small as possible from its sealing and strength view-point. Too large an aperture will permit too large an amount of content to be let out at once, whereas too small an aperture will offer large resistance to flow-out of powder, detracting from its smooth streaming. It is, therefore, advantageous to permit its contents to be let out smoothly at a desirable flow rate without stagnation, while making the aforementioned opening as small as possible.
  • the inner plug according to the present invention has a construction which permits its manufacture by integral molding at a low cost.
  • FIGS. 1 and 2 show a first embodiment of this invention
  • this inner plug is integrally molded of a thermoplastic synthetic resin material and is composed of a planar circular top board 1 and a cylindrical cir­cumferential wall 2 extending from the peripheral rim of said top board.
  • Said top board 1 is formed in a concave shape bulged downward. This concave shape is a little eccentric so that the lowest portion 1a of the concave surface is brought toward the peripheral rim side of the top board. And at this lowest part, an aperture 3 for letting its content out is formed.
  • the aforementioned aperture 3 is closed with a membrane cap surrounded by a thin circular groove 4a which permits its tearing-off.
  • a ringed tag 5 for its tearing-off is contiguously provided.
  • This tag should not necessarily be formed in a ring shape, but it may be in string or other shapes.
  • a large diameter flange part 7 which works as a packing for the outside cover B is formed, whereby favorable sealing is ensured, as the container has been hermetically closed.
  • FIGS. 4, 5 and 6 by forming ring shape protrusions 7a along the upper or lower or both upper and lower surfaces of this flange, still higher sealing effect may be achieved. Or this flanged part 7 may be omitted, as shown in FIG. 7.
  • a weir 6 extending downward around the aforementioned aperture 3 is formed on the bottom surface of the aforementioned top board 1,powder will come abutting on this weir, to be branched, when letting its content to flow out, where­by the resistance to flow at the opening is releaved, assuring smooth streaming without stagnation.
  • divided weir parts may be formed at an appropriate distance apart.
  • a baffle plate 15 which shields the part downward of the membrane cap 4 may be formed, extending from the top board 1, as shown in FIGS. 10 and 11, whereby like the aforementioned weir 6, the resistance to flow-out through this opening may be releaved.
  • an oxygen adsorber 8 or drier 9 or both in the upper space formed by the concavity of the afore­mentioned top board 1.
  • the oxygen and moisture inside the container penetrates the thin groove part of the top board 1, to be absorbed by this oxygen absorber 8 or drier 9, so that the amount of oxygen inside the container or the water content of the powder therein may be suppressed low.
  • the oxygen and moisture penetrated from the outside of the cover B may be suppressed low, and after the membrane cap was opened, increase of the oxygen or moisture in the powder may be suppressed low.
  • a covering plate 16 which overspreads upward of the mem­brane cap 4 is provided at the perimeter of the upper surface of the top board 1, the space between this covering plate 16 and the concave upper surface of the top board 1 forming a quantitative measuring chamber 17.
  • this quantitative measuring chamber 17 an opening 18 is formed, looking toward the top board center.
  • the powder since the powder may be stored in the aforementioned quantitative measuring chamber 17, as shown in FIG. 15, by tilting this container for letting its content out, it may be let flow out through the opening 18 by tilting the container to the opposite direction by the next operation.
  • part of the powder inside the quantitative measuring chamber may fall down into the container through the opening formed by removal of the membrane cap 4; if this fall­ing amount has been calculated beforehand, a quanti­tative discharge will become possible to some degree.
  • powdered beverages as powdered coffee or milk, etc., which do not require strictly quantitative dis­charge, their handling may be adequately exercised by such a mechanism embodying this invention.
  • the aforementioned inner plug may be used in a wide mouthed container A injection-molded with a synthetic resin material, as shown in FIG. 3, by putting the plug in its mouth, after filling powder thereinto.
  • the plug may be either closely fit in the aforementioned mouth or bonded thereto by welding with high frequency.
  • a stepped portion 13 is provided on the inner surface of the mouth of the container A, on which the flanged portion 7 of the inner plug is engagingly fit, and the mouth's upper opening is sealed with an aluminum film 14, then, still more positive hermetic closing can be achieved.
  • FIG. 16 shows another embodiment of this invention, wherein the aperture 3 is opened beforehand; a cylindrical wall 19 is provided along the peripheral rim of this aperture and on the top of this cylindrical wall, a cap 20 for closing said aperture is removably put.
  • the top board being formed in concave shape, the top board strength can be increased, permitting the material thick­ness to be reduced as much as possible for economy; and when letting any powdery content of the container flow out, it will flow to the low part on the perimeter at the back of the top board, to be led to the aperture formed in proximity to the perimeter of the top board, so that even if the aperture is formed small, the powder may be smoothly let out through this aperture; in addi­tion, since a tearing knob 4 may be housed in the top space formed by the concavity of the top board, it is not only possible to form the container compact and smart in its external appearance, but to contain oxygen absorber and drier in said space. Particularly, as shown in FIGS.
  • the aperture 3 may be opened only after tearing off part of the top plate before using the powder; therefore, the container is proofed against tampering, or its virginity ensured.
