Definitions

  • the present invention relates to plastic closures for fluid containers that dispense product through a container opening upon application of hand pressure.
  • Prior art closures for fluid containers are myriad in design and construction. These often require complicated molding, assembly of parts, are expensive to manufacture, do not close and seal properly, do not provide a variable closure opening dependent on the hand pressure used to dispense, are subject to opening upon inadvertent squeezing, and/or are of a shape not conducive to easy handling and shipping.
  • Prior art U.S. Patent No. 1,977,227 (1934) discloses a closure wherein panels are separately placed in a mold in an overall frusto-conical shape, with rubber then poured over and under the panels to form a resilient part between the panels. An opening slit is then cut in the rubber.
  • the frusto-conical shape of the panels is the closed position of the closure, and the panels cannot be folded to a flat position for ease of handling and shipping. Accordingly, the rubber is not folded in either the open or closed positions of the closure, and the sides of the panels are always separated. This i ⁇ ulti-piece closure among other deficiencies is labor intensive and expensive to manufacture.
  • the present invention is intended to provide a plastic one-piece container closure which is strongly constructed, easily and cheaply manufactured, requires no assembly, functions reliably and efficiently, closes and seals properly, provides a variably-sized closure opening depending on hand pressure of the user, does not inadvertently open, and is easy to handle and ship by virtue of its shape.
  • the closure will be used to dispense lotions and various other fluid products from a container.
  • the closure has an annular collar for attachment to the container about its opening.
  • a plurality of leaflets are attached by hinges to the collar, and a plurality of flexible and foldable webs are attached to and extend between adjacent pairs of leaflets.
  • the leaflets extend adjacent one another in an essentially flat horizontal configuration in the closed position of the closure with the webs folded in pleats beneath the adjacent leaflets.
  • the leaflets pivot upwardly at their hinges under the influence of fluid pressure.
  • the leaflets separate from one another upon upward pivoting and the webs unfold and extend between the separated leaflets to form with the leaflets the closure dispensing opening.
  • the leaflets are quasi-triangular in shape, having long sides that converge toward the central axis of the closure.
  • the webs are attached to the long sides of the leaflets.
  • a cap for the closure is integrally attached to the collar by a snap-action, bow-tie hinge.
  • the cap has a central pin in its undersurface that seals against the radially innermost portions of the leaflets upon closing the cap into the closure.
  • the closure for the present invention is molded as a unitary member.
  • the closure is initially molded in the open position with the leaflets extending angularly upward and separated from one another, and with the webs unfolded and extending between adjacent pairs of leaflets. Thereafter, while the leaflets and hinges are warm, the leaflets are pivoted downwardly to the closed closure position where the leaflets extend adjacent one another in an essentially planar surface and the webs are folded beneath the adjacent leaflets. Upon cooling, the elastic positional memory of the closure accordingly is in the closed position.
  • Fig. 1 is a perspective view of the closure of the present invention in closed position but with its then normally closed cap open for clarity of illustration;
  • Fig. 2 is a perspective view of the closure of the present invention in open position
  • Fig. 3 is a cross-sectional view of the closure of the present invention in closed position but with its normally closed cap open;
  • Fig. 4 is a top plan view of the closure of the present invention in closed position but with its normally closed cap open;
  • Fig. 5 is a fragmentary view taken from Fig. 3 and illustrating in cross-section the hinging of the leaflets to the collar in the closure of the present invention
  • Fig. 6 is a cross-sectional view of the closure of the present invention in open position.
  • Fig. 7 is a top plan view of the closure of the present invention in open position.
  • Fig. 8 is a rear elevational view of the closure of the present invention in closed position and illustrating the bow-tie hinge connecting the closure cap to the closure collar.
  • plastic closure 10 is shown having annular collar 11 for attachment to a fluid container
  • Attachment for example may be by threads 12 (see Fig. 3) , snap fittings (not shown), or other known attachment means.
  • a plurality of leaflets 13 are positioned at the top of collar 11 and are attached by integral hinges 14 (see in particular Fig. 5) to collar 11. Eight such leaflets 13 are shown, although the number may obviously vary.
  • leaflets 13 are shown in Figs. 1,3,4 and 5 extending adjacent one another in an essentially flat horizontal surface.
  • Each leaflet 13 is a quasi-triangular shape having two long sides 15 that converge in a direction away from the hinge 14 associated with the particular leaflet 13. The long sides 15 of each leaflet 13 lie adjacent the long sides of adjacent leaflets 13 in the closed position of closure 10.
  • Integrally attached to and extending between the leaflets 13 are a plurality of thin, flexible and foldable webs 16, webs 16 each extending between and attached to the long sides 15 of two adjacent leaflets 13.
  • Webs 16 might be of the order of .005 inches thick and leaflets 13 might be of the order of .040 inches thick, solely as an example.
  • each web 16 folds beneath the adjacent pair of leaflets 13 and the long leaflet sides 15 lie adjacent one another.
  • the closure opens the long leaflet sides 15 will be spaced from one another.
  • Closure 10 will generally be attached to a squeezable fluid container, for example. When the container is manually squeezed, the pressure of the fluid to be dispensed forces the leaflets 13 from their essentially planar Fig.
  • Closure 10 also includes cap 20 integrally attached to collar 11 by bow-tie hinge 21.
  • Cap 20 has central pin 22 and surrounding surface 23 extending from the under surface (when closed) of the cap 20.
  • Bow-tie hinge 21 snaps between the open and closed positions of cap 20 on closure 10.
  • central pin 22 extends into central opening 18 at the central axis of the closure defined by the radially inward tips 19 (see Fig. 4) of leaflets 13. Tips 19 seal against central pin 22.
  • Under surface 23 of cap 20 acts to hold leaflets 13 flat in the closed cap position.
  • Snap means may be provided for cap 20 to snap at its periphery onto the periphery of collar 11 in the closed position.
  • the bow-tie hinge 21 acts to hold cap 20 in closed position even in the presence of accidental squeezing of the container.
  • Collar 11, leaflets 13, hinges 14, webs 16, cap 20 and bow-tie hinge 21 may all be integrally molded with one another into a one-piece plastic closure, in a single molding operation.
  • the plastic may be polypropylene, for example.
  • the closure is molded in a single molding operation of all the parts into the orientation of parts as shown in Fig. 2. Webs 16 are therefore molded in their unfolded position. Thereafter, while the hinges 14 and leaflets 13 are still warm, the leaflets 13 are pivoted downwardly to the closed Fig. 1 position. Webs 16 accordingly fold under the leaflets 13.

Abstract

La présente invention concerne une fermeture de récipient d'un seul tenant comportant un col, des feuillets fixés par des charnières au col et de minces voiles pliables souples fixés aux feuillets et s'étendant entre eux. Les feuillets sont plats, les voiles étant pliés au-dessous en position fermée. Les feuillets pivotent vers le haut, les voiles étant dépliés entre eux en position ouverte. Un capuchon intégré est fixé au col par une charnière papillon à déclic. Une broche centrale sur le capuchon scelle les feuillets lorsque le capuchon est fermé. La fermeture est entièrement moulée en position ouverte, les feuillets dressés et les voiles dépliés, les feuillets étant ensuite abaissés et les voiles pliés en position fermée alors que la fermeture est encore tiède.
