Definitions

  • the present invention relates to a manual type liquid discharge container such as a spraying container, a foaming container or a container for discharging liquid as it is, and a container capable of selecting one of spray, foam and liquid by switching a liquid passage formed in a head.
  • a foaming container or a container for discharging a liquid as it is there is commercially sold a liquid discharge container which comprises: a container body; a cylinder depending into the container body from a cap-shaped member fitted on the outer face of the mouth/neck portion of the container body; and an actuator having a stem erected through the top wall of the cap-shaped member on a cylindrical piston, which is fitted in the cylinder, and a head fitted on the upper end of the stem and having a nozzle opened forward.
  • the actuator is moved up and down with respect to the cylinder for sucking a liquid in the container body into the cylinder and discharging the liquid in the cylinder out of the nozzle through the stem.
  • a container which is enabled to select one of those spray, foam and liquid by switching a liquid passage formed in the head.
  • these containers have different nozzle structures but are substantially similar except the structure of the head having the nozzle.
  • the actuator composed of the cylindrical piston, the stem and the head is biased upward by the spring so that it is raised back by the spring after it has been depressed.
  • the depression of the actuator is accomplished against the biasing force of the spring so that it requires a considerable force.
  • the present invention contemplates to provide a liquid discharge container which overcomes these problems.
  • DE-U-6753424 discloses a liquid discharge container comprising: a container body; a cylinder depending into said container body from a cap-shaped member fitted on the outer face of the mouth/neck portion of said container body; an actuator having a stem erected through the top wall of said cap-shaped member from a cylindrical piston, which is fitted in said cylinder, and a head fitted on the upper end of said stem and having a nozzle opened forward and a ring-shaped finger knob, said actuator being moved up and down with respect to said cylinder for sucking a liquid in said container body into said cylinder and discharging the liquid in said cylinder out of said nozzle through said stem.
  • a liquid discharge container having the features as set forth in the preamble of the claim, is characterized by the features as follows from the characterizing clause of the claim.
  • the problem of making pulling up easier is solved by the cooperation of the auxiliary walls with the absence of spring.
  • auxiliary walls acting as a finger grip and guiding the head are so erected from the righthand and lefthand two side portions of the top wall of the cap-shaped member along a righthand and lefthand two side faces of the head as to allow the vertical movements of said head.
  • auxiliary walls 6 and 6 of Figure 8 which are erected along the righthand and lefthand side portions of the top wall of the cap-shaped member, partly provide a finger grip, when the container is held at its upper portion by the hand, and partly guide the head 18 when the head is moved down, to prevent the head from moving to the right and left.
  • the actuations of moving the actuator up and down by the finger are facilitated while at the same time the stroke of the actuator can be increased.
  • Reference numeral 1 designates a container body having an erected mouth/neck portion 2. On the outer face of the mouth/neck portion, there is screwed the lower half of a circumferential wall 5 which depends from the outer circumference of the top wall of the cap-shaped member 3. Said member is formed with a hole 8 at the central portion of the top wall 4. The upper half of the circumferential wall is radially reduced to have a smaller internal diameter than the external diameter of the mouth/neck portion, and the reduced portion has its lower end face mounted through a packing 9 on the upper end face of the mouth/neck portion.
  • a short cylinder 12 which is erected from the outer circumference of an external flange 11 formed in the upper portion of a cylinder 10.
  • This cylinder 10 has a larger diameter portion 10a at its upper portion and a smaller diameter portion 10b at its lower portion and is equipped in the inner face of its lower end with a suction valve 13 of a ball valve.
  • a pipe 14 depends to the bottom portion of the container body from the lower end of the cylinder 10.
  • An air vent hole 15 is formed in the aforementioned larger-diameter portion 10a.
  • a stem 17 which is equipped with a cylindrical piston 16 at its lower end.
  • a head 18 On the upper end of said stem, there is fitted a head 18 which has a nozzle 19 opened forward.
  • the cylindrical piston 16 and the stem 17 may be made of different members, as shown.
  • the cylindrical piston has its smaller-diameter cylindrical portion 16b erected from the upper end of its cylinder portion 16a through an inward flanged portion and fitted in the lower portion of the stem 17.
  • These cylindrical piston 16, stem 17 and head 18 constitute altogether an actuator 20, which is equipped with a discharge valve.
  • This discharge valve is formed in the shown embodiment by fitting a valve member 21, which has longitudinal grooves in its outer face, vertically moveable in the stem 17 so that it is defined by the lower end face of said valve member and the upper end of the bore of the aforementioned smaller-diameter cylinder portion.
  • the valve member 21 is biased downward by a spring 22 which is fitted in the stem. This spring has its upper end engaging with the lower face of the inward flange fonned at the upper end of the stem.
  • a sliding cylinder 25 which has its lower portion fonned on its outer circumference with a ring-shaped sealing member 26 fitted in the cylinder larger-diameter portion 10a and which has its lower end engaging with the upper end face of the cylinder portion of tlie cylindrical piston 16.
  • said sliding cylinder is moved down together with the stem 17 by depressing the head 18, until it is stopped when said sealing member has its lower end contacting with the upper end of the cylinder smaller-diameter portion 10b so that the sealing member 26 shuts out the air vent hole 16.
  • the stem 17 is further moved down with respect to the sliding cylinder 25.
  • the cylindrical piston has its cylinder portion 16a contacting with the lower end of the sliding cylinder 25 to push up said slider cylinder. If the container has its inside evacuated as the liquid decreases, the sealing member 26 is moved upward of the air vent hole 15.
  • the ambient air is introduced into the container body through the clearance between the inner edge of the hole 8 and the outer face of the sliding cylinder 25, through the clearance which is established between the sealing member 26 and the inner face of the larger-diameter portion of the cylinder by deforming said sealing member elastically, and through the air vent hole 15.
  • the nozzle opened in the front face of the head is used for atomizations.
  • a foaming container or a liquid discharge container either, as is well known in the art, by changing the nozzle structure into a foaming one or by making a head for discharging a liquid as it is.
  • a ring-shaped finger knob 30 which has its ring hole directed forward or backward. Said finger knob is sized to admit the finger tip into the ring-shaped portion. Said finger knob 30 has its finger hole 31 opened forward or backward.
  • auxiliary walls 6 and 6 for acting as the finger grip and guiding the head are erected from the righthand and lefthand two portions of the top wall 4 of the cap-shaped member 3 of Fig. 1, and a rear wall 7 for connecting the rear portions of the lower halves of those auxiliary walls is erected from the rear portion of the top wall.
  • the head 18 is formed generally into such a square shape that it can be moved up and down while having its righthand and lefthand side faces contacting with the inner faces of the auxiliary walls 6 and 6.
  • auxiliary walls 6 and 6 can be added to a variety of cap-shaped members 3, more specifically described in EP 05 13 350 A1.
  • the auxiliary walls acting as the finger grip and guiding the head are so erected from the righthand and lefthand two side portions of the top wall of the cap-shaped member along the righthand and lefthand two side faces of the head as to allow the vertical movements of the head.
  • the actuator can be operated by gripping the upper portion of the container body and the lower portions of the auxiliary walls when the container is held for operating the actuator.
  • the grip position of the hand can be made higher than that of the case of no auxiliary wall, to raise the finger tip engaging with the finger knob thereby to increase the stroke of the actuator.
  • the head can be prevented from shaking by the guidance of the auxiliary walls, while it is being moved up and down, so that the operation of the actuator be facilitated.
