Definitions

  • Flacons and similar relatively small bottles of glass or plastic are normally sealed by stoppers in the form of metallic or plastic caps which are provided with flaps to facilitate their detachment from the open end portion of the bottle.
  • stoppers are often utilized in connection with bottles which contain a relatively small quantity of flowable material, i.e., a quantity which is just sufificient for a single use so that the stopper and the bottle can be discarded after a single application or other utilization of the contents.
  • a serious drawback of such stoppers is that their detachment from the bottle requires the exertion of considerable force so that the user is often compelled to resort to pliers, knives, scissors or other tools which are likely to injure the fingers.
  • stoppers cannot be reapplied if the user wishes to interrupt the utilization of the contents of a bottle or to save some of the contents for a later use.
  • vials or fiacons consisting of synthetic plastic material are provided with integral stoppers or corks which are joined to the bottle neck by a relatively weak web of readily breakable material so that the user can open the bottle by breaking off the stopper.
  • stoppers are unsatisfactory when the bottle is used for storage of fiowable materials containin alcohol or another volatile substance. It was found that the volatile substance will readily evaporate through a relatively thin web of synthetic plastic material, even at room temperature, so that the volume of the contents of such bottles decreases on prolonged storage and the stored material might not be satisfactory for use when the purchaser decides to break off the integral stopper.
  • the web is made .too thick so that it prevents evaporation of volatile substances, the user must exert a very strong force or must resort to auxiliary tools in order to gain access to the contents.
  • Another object of the invention is to provide a stopper of the just outlined characteristics which can be utilized on receptacles for flowable materials containing alcohol or other volatile substances likely to penetrate through relatively thin layers of synthetic plastic material.
  • a further object of the invention is to provide a stopper which can be applied to or detached from a receptacle without necessitating the utilization of any tools.
  • a concomitant object of the invention is to provide a stopper which can properly seal mass-produced vials, flacons and analogous receptacles even if such receptacles are not finished with utmost precision.
  • Another object of the invention is to provide a receptacle which can be utilized in connection with the improved stopper.
  • one feature of our present invention resides in the provision of a one-piece stopper or cork which can be utilized in connection with small bottles or analogous receptacles consisting of vitreous, metallic, plastic or other suitable material and having an open end portion provided with an annular internal face, an annular top face extending outwardly from the outer end of the internal face and a second annular face extending outwardly from the inner end of the internal face.
  • the stopper comprises a handgrip portion and an elastic sealing portion which later comprises an annular sealing surface movable into abutment with the top face of the end portion, and a second annular surface which is spaced from the sealing surface and diverges conically outwardly.
  • This second surface can be introduced through the internal face of the end portion and is then caused to bear against the second face because the distance between the two annular surfaces of the sealing portion is preferably less than the distance between the top face and the second face.
  • the neck of the sealing portion which extends between the two annular surfaces is caused to expand or to stretch axial- 1y when the second surface abuts against the second face whereby the sealing surface is caused to bear against the top face of the end portion to thereby provide a fiuidtight seal between the stopper and the receptacle.
  • the stopper can be inserted in response to axial pressure against its handgrip portion and is detachable from the receptacle in response to pressure transmitted to the handgrip portion in a direction substantially radially of the sealing portion. During the application of such radial pressure, the conical second surface of the sealing portion is compelled to enter the space surrounded by the internal face of the end portion and the stopper is then readily removable by exertion of a pull upon the handgrip portion
  • FIG. 1 is a fragmentary axial section through the open end portion of a bottle and through a stopper which is constructed and configurated in accordance with our invention, the stopper being shown in an intermediate position during introduction of its sealing portion into the end portion of the bottle; and
  • FIG. 2 shows the structure of FIG. 1 but with the stopper in sealing position.
  • FIG. 1 shows a portion of a vital, fiacon or an analogous relatively small receptacle 1 having an open end portion 1a bounded by an inwardly inclined internal annular face 5 which diverges conically frornits inner end toward its outer end, an annular top face 3 which is preferably located in a plane making right angles with the axis of the end portion 1a and extends radially outwardly from the outer end of the internal face 5, and a second or outwardly inclined internal annular face 4 which diverges conically from the inner end of the conical internal face 5.
  • the receptacle 1 is assumed to consist of synthetic plastic material which might but need not be slightly elastic.
  • the faces 3, 4 and 5 of the end portion 1a can be readily finished with a degree of precision which is satisfactory for our purposes, i.e., for proper application of a novel stopper 2 which comprises a cylindrical or conical handgrip portion 2a and a specially configurated sealing portion 2b having a leading end.
  • the portions 2a, 2b of the stopper 2 may but need not be hollow.
  • at least the sealing portion 2b of the stopper consists of elastic synthetic plastic material, such as polyethylene.
  • the sealing portion 2b constitutes the important part of the stopper 2.
  • This sealing portion has an annular sealing surface 6 which can be moved into sealing engagement with the top face 3 of the end portion 1a, a conically diverging, forwardly and outwardly inclined outer or second annular surface or face 7 which is axially spaced from the sealing surface 6 by a distance which at most equals the axial distance between the faces 3 and 4 (when the sealing portion 212 is allowed to return to unstressed condition), and a third or rearwardly and outwardly inclined outer annular surface or face 8 which diverges conically from the surface 7 toward the surface 6 and is surrounded by the internal face 5 when the sealing portion 2b assumes the sealing position shown in FIG. 2.
  • the annular neck 9 of the sealing portion 2b which is surrounded by the conical surface 8 undergoes at least some axial expansion when the leading end 10 of the sealing portion 2b is introduced through the space surrounded by the internal face 5 so that the conical surface 7 bears against the conical face 4. Satisfactory results will be obtained if the face 4 is not conical but is located in a plane which is parallel to the plane of the top face 3.
  • the user introduces the leading end 10 into the interior of the end portion 1a and exerts finger pressure in the axial direction as indicated in FIG. 1 by an arrow C. Since the material of the sealing portion 2b is deformable, the leading end 10 can be readily forced through the internal face 5 and expands when the conical surface 7 comes into engagement with the conical face 4. Such engagement between the surface 7 and face 4 produces a wedging action, i.e., the neck 9 is subjected to axially directed expanding stresses and the sealing surface 6 is biased against the top face 3 to provide a highly satisfactory sealing action.
  • the user applies finger pressure against the handgrip portion 2a in the direction as indicated in FIG. 2 by an arrow D, i.e., substantially radially of the end portion 1a and sealing portion 2b, whereby the leading end 10 is forced to enter the space within the internal face 5 and the sealing portion 2b is expelled from the end portion 1a in response to expansion of its elastic material. If the pressure exerted in the direction of the arrow D was relatively small, the user will complete the separation of the stopper 2 by exerting a pull upon the handgrip portion 2a.
  • a very important advantage of the improved stopper is that the main sealing action takes place between the sealing surface 6 and the top face 3. Thus, evaporation of volatile ingredients is practically impossible as long as the wall thickness of the end portion la sufiices to prevent evaporation.
  • the wall thickness of the neck 9 is preferably less than that of the remainder of the sealing portion 2b so that this neck can readily extend in response to engagement of the conical surface 7 with the conical face 4.
  • leading end 10 of the sealing portion 2b resembles a hollow truncated cone
  • leading end serves as a guide during introduction of the sealing portion into the end portion 1a and undegroes gradually increasing radial compression as it slides along the conical internal face 5 to move the conical surface 7 into engagement with the conical face 4.
  • the faces 3 and'S of the end portion 1a are calibrated so that their dimensions are within a predetermined range. Such calibration can be readily achieved in a blow mold.
  • the improved stopper can be used in connection with receptacles wherein the internal face 5 has a constant diameter from end to end, as long as the surface 7 of the sealing portion 2b resembles a cone.
  • a receptacle comprising an open end portion bounded by an inwardly inclined internal annular face having an outer end, an annular top face extending outwardly at said outer end, an inner end and an outwardly inclined internal annular face extending inwardly from said inner end, with a stopper comprising a handgrip portion and a sealing portion of elastic material receivable in said open end portion, said sealing portion having a leading end and being provided with a forwardly and outwardly inclined outer annular face having a rear end and a rearwardly and outwardly inclined outer annular face extending rearwardly from said rear end, said forwardly and outwardly inclined outer annular face of said sealing portion bearing against said outwardly inclined internal annular face of said open end portion when the latter receives said sealing portion, so that said rearwardly and outwardly inclined outer annular face of said sealing portion is biased against said inwardly inclined internal annular face of said open end portion of said receptacle, and an annular sealing surface provided on said sealing portion
  • top face is located in a plane which is substantially normal to the axis of said open end portion.
  • sealing portion comprises a neck bounded by said outwardly inclined outer annular face and surrounded by said inwardly inclined internal annular face when said outwardly inclined outer annular face engages said outwardly inclined internal annular face.
  • a receptacle comprising an open end portion bounded by an annular internal face having an inner end and an outer end and diverging conically from said inner end toward said outer end, an annular top face extending outwardly at the outer end of said internal face, and a second annular face extending outwardly at the inner end of said internal face, with a stopper comprising a handgrip portion and a scaling portion of elastic material receivable in said open end portion, said sealing portion having an annular sealing surface movable into abutment with said top face, a second annular surface diverging conically outwardly and spaced from said sealing surface by a distance which at most equals the distance between said top face and said second face, and a third surface between said sealing surface and said second surface and diverging conically toward said sealing surface, said third surface being surrounded by said internal face and said second surface bearing against said second face when said open end portion receives said sealing portion so that said sealing surface is biased against said top face.
  • said second face diverges conically outwardly from the inner end of said internal face
  • said third surface is an outer surface of a neck provided 011 said sealing portion extending between said surfaces and being re ceived with at least some axial expansion within said internal face when said sealing surface and said second surface respectively abut against said top face and said second face.
