Definitions

  • An essential object of the invention is to keep the outlet opening of the closure constantly free of residues.
  • the closure comprises a cap of resilient material, which returns to its original position after a deformation and which is mounted on a container head having an outlet opening, said cap having a continuous slit, which opens under the iniiuence of a pressure produced in the interior of the container, and means being provided for sealing the slit when the container is not being used.
  • FIG. 1 shows the upper portion of a tube with a tube head shown in axial section.
  • FIG. 2 is a sectional view taken on line II-II of FIG. l.
  • FIG. 3 is a top plan view showing the tube head when the closure member has been removed.
  • FIG. 4 is an axial longitudinal sectional view showing another embodiment of a tube closure.
  • FIG. 5 is an axial longitudinal sectional view showing a further embodiment of a tube closure for being screwed onto tubes having a conventional screw-threaded neck.
  • FIG. 6 is a top plan view showing the tube closure according to FIG. 5.
  • FIG. 7 is a longitudinal sectional view showing another embodiment of a tube closure.
  • FIG. 8 is ⁇ a perspective view showing ⁇ a detail of FIG. 7.
  • FIG. 9 is an axial longitudinal sectional view showing a fifth embodiment of the tube closure.
  • FIG. 10 is a perspective view showing a detail of FIG. 9.
  • the neck 1 of the tube 2 has a hemispherical top portion 3, which has two cardioid outlet openings 5, which are separated by a web 4.
  • the top portion 3 is covered by a cap 6 of resilient material, such as rubber or plastic, which returns to its original shape after a deformation.
  • the lower rim 7 of the cap 6 is turned inwardly and around the free rim 8 of the top portion 3.
  • the cap 6 Adjacent to the web 4, the cap 6 has a slit 9, which may be made, for instance, in a simple manner by cutting through the cap and which is covered by a lug, or strap, 10, which is at one end integrally joined to the cap 6 close to the rim of the later whereas the other end of the lug has an opening 11, which cooperates with a knob 12 extending from the tube so that the lug is held under initial stress.
  • a slit 9 may be made, for instance, in a simple manner by cutting through the cap and which is covered by a lug, or strap, 10, which is at one end integrally joined to the cap 6 close to the rim of the later whereas the other end of the lug has an opening 11, which cooperates with a knob 12 extending from the tube so that the lug is held under initial stress.
  • the tube When pulled from the knob 12, the lug 10 springs 3,224,930 Patented Dec. 21, 1965 up to expose the slit 9.
  • the cap 6 When the pressure ceases, the cap 6 closes owing to its resiliency and tightly engages the web 4 so that the suction created in the tube if its deformation is reversed cannot cause air to enter, which might cause a deterioration or drying of the contents of the tube.
  • the tube neck is inclined from the axis of the tube and the lug 10 is provided with a brush 13, a sponge or the like for spreading the mass squeezed out of the tube, for instance, on a surface.
  • a brush 13 e.g., a sponge or the like for spreading the mass squeezed out of the tube, for instance, on a surface.
  • Such a tube may be used, eg., for shoe polish.
  • the lug 10 is shown in this figure in its open position in dotted lines.
  • the tube closure shown in FIGS. 5 and 6 enables the provision of existing tubes having a screw-threaded neck with a tube closure embodying the invention.
  • a spout member 14 is provided, which has an extension 16 formed with a female screw thread 15, by which the spout member 14 is screwed onto the screwthreaded neck of a tube of usual type.
  • the cap 6, which is pot-shaped in this case, is fitted over the top of the spout 14.
  • the slit 9 is not arranged in the axial center plane of the spout but laterally, near the top rim of the spout.
  • the lug 10 is replaced by a second cap 17, which constitutes a rotary closure and is fitted onto the spout 14 together with the cap 6 from below over the extension 16.
  • the cap 17 is held on the cap 6 by laterally bent lugs 18 and is formed with a diagonal step 19, which is so high that the upper rim 20 of the lower half 21 of the cap 17 is below the slit 9 of the cap 6.
  • the higher portion of the cap 17 covers the slit 9 and thus performs the function of the lug 10 described hereinbefore.
  • the cap 17 is first turned through so that the lower portion 21 of the cap 17 lies over the portion of the cap 6 formed with the slit 9, which is thus exposed.
  • the closure has the same mode of operation as that of the preceding embodiment.
  • FIGS. 7 to 10 show further possibilities of mounting the closure according to the invention on conventional tubes, the neck of which has a laterally protruding rim 26 or a similar projection.
  • a ring 23 is placed on the free top surface 22 of the neck 1.
  • the ring 23 is connected to a bail 24, which extends diametrically across the ring.
  • the ring and bail are suitably integral and may be made from metal or plastics.
  • the cap 6, which is known from preceding embodiments, is applied to the bail 24.
  • the lower rirn 7 of the cap 6 engages the protruding rim 26 of the neck from below.
  • the slit 9 consists again of an incision and is disposed exactly over the bail 24.
  • Two lugs 25 are provided on the inside of the cap adjacent to this slit. These lugs straddle the bail like a roof and contact each other along a portion of their height to increase the tightness of the closure.
  • the lug 10, which has already been described, may be hooked to a knob 12, the arangement of which differs from that of FIG. 4 in that the konb is connected to the ring 23 and extends through the cap 6.
  • the tube closure shown in FIGS. 9 and 10 differs from the embodiment described last in that there are two bails 24 and 24", which unlike the bail 24 do not cover the slit 9 but act like a clamp to force the lugs 25 together.
  • the 4lugs 25 are suitably upwardly tapered to match the angle between the bails.
  • a closure for squeezable containers, particularly tubes, having a head provided with an opening comprising a cap of resilient material, which returns to its original position after a deformation and which is mountable on said container head, said cap having a continuous slit, which opens under the influence of a pressure produced in the interior of a container on which the cap may be mounted, and means for sealing the slit when the container is not being used including a lug on the cap overlying said slit and having a free end adapted to be Xed to a stationary closure part, said lug being provided with means for applying the contents of the container.
  • a closure according to claim 1 wherein said lug comprises a strap of resilient material secured near one end to the cap, the other end of the strap being swingable about said secured end to uncover the slit.
  • a closure according to claim 2 wherein said lug means for applying the container contents comprises a brush aixed to the outer surface of said strap.
  • said means for sealing the slit further comprises a bail, which engages the bottom of said slit and is integral with a ring adapted to seat on the head of the container for spacing and supporting said cap.
