Definitions

  • the present invention relates to a cap for a squeeze container, and in particular, relates to a cap for a squeeze container to be used as being attached to a mouth neck section of a plastic-made container body which is squeeze-deformable.
  • a squeeze container discharges a specific amount of content liquid from a discharge opening toward a discharge position owing to deformation of a container body by being squeezed (i.e., compressed) as a barrel section of the container body being held with a hand.
  • the squeeze container is used as having a cap with the discharge opening attached to the mouth neck section of the squeeze-deformable plastic-made container body in a detachably attachable manner so that content liquid can be supplemented or replaced.
  • content liquid is discharged by a specific amount by squeezing the container body in a state that the discharge opening is directed to a discharge position as tilting or inverting the held squeeze container after an outer cover which covers the discharge opening is removed, for example.
  • Patent Literature 1 liquid leaked before squeezing is prevented from being stuck to the vicinity of a container body by arranging a side wall at a cap to which a discharge opening is formed at the center of a top face section as being obliquely extended toward the center side from a peripheral section of the top face section.
  • liquid stopping is worsened owing to insufficient liquid sucking with back suction.
  • Patent Literature 2 content liquid is not discharged unless a container body is squeezed so that occurrence of unnecessary liquid dripping can be effectively avoided by arranging liquid inflow opening at the vicinity of the discharge opening as bending a dip tube which is communicated with the discharge opening of a cap to be a U-shape.
  • the U-shaped bent tube structure causes inconvenience for handling at the time of attaching and detaching of the cap.
  • squeezing is performed in a state that content liquid remains at the inside of the dip tube, there may be a case that liquid is splashed peripherally owing to air mixing.
  • Patent Literature 3 occurrence of liquid dripping is avoided as returning liquid which remains in a trap room by fixedly arranging a closed-end cylindrical trap room at a lower side of a discharge opening section and forming communication holes at a periphery wall section and a bottom section of the closed-end cylindrical body.
  • liquid cannot be discharged until liquid is accumulated to a certain level in the trap room, there may be a problem such that a discharge amount is lessened or cannot be adjusted especially at the first time. Accordingly, discharge amount stabilization, liquid dripping prevention and preferable liquid stopping are not sufficiently satisfied even in any of the above cases. Therefore, further technology development to prevent such problems has been desired.
  • the present invention relates to a cap for a squeeze container with which leaking and dripping of container liquid before squeezing can be effectively prevented, favorable liquid stopping with back suction can be obtained, a compact shape for easy handling during attaching and detaching of the cap can be obtained, and air mixing with content liquid can be effectively prevented as well.
  • the present invention provides a cap for a squeeze container to discharge content liquid from a top discharge opening with squeeze deformation of a barrel section of a container body to be used as being attached to a mouth neck section of the container body made of plastic as being squeeze-deformable. Further, the present invention provides a cap for a squeeze container having a helical flow path at least as a part of a liquid flow path from the mouth neck section of the container body to the discharge opening.
  • FIG. 1 illustrates a squeeze container 11 to which a cap 10 for a squeeze container according to the first embodiment preferable for the present invention is attached.
  • the cap 10 for a squeeze container is used as being attached to a mouth neck section 12a of a plastic-made container body 12 which is squeeze-deformable.
  • the cap 10 for a squeeze container has a discharge opening 13 as being opened at the top end and a specific amount of content liquid can be discharged by feeding the content liquid to the discharge opening 13 of the cap 10 for a squeeze container from a barrel section 12b via the mouth neck section 12a with deformation of the container body 12 as squeezing (i.e., compressing) the barrel section 12b of the container body 12 after the discharge opening 13 is directed to a discharge position while a user tilts or inverts the squeeze container 11 as grasping the barrel section 12b of the container body 12.
  • squeezing i.e., compressing
  • the cap 10 for a squeeze container has a function enabling to prevent leaking and dripping of content liquid from the discharge opening 13 owing to internal pressure of the container body 12 and self-weight of the content liquid after the discharge opening of the squeeze container 11 is directed to a discharge position until the barrel section 12b of the container body 12 is squeezed.

  • the discharge opening 13 is formed as vertically penetrating through the cylindrical intermediate section 19b and the nozzle body 19a of the nozzle section 19.
  • a cover body 16 capable of opening and closing the top end opening of the nozzle body 19a is swingably joined to the nozzle body 19a via a hinge section 17. Accordingly, the discharge opening 13 is hermetically closed at the time of storage of the squeeze container 11.
  • an internal thread is formed, for example, at the inner face of an approximate half part of the annular-shirt-shaped peripheral wall section 10b.
  • the cap 10 is attached to the mouth neck section 12a in a detachably attachable manner by fastening the internal thread to an external thread which is formed at an outer peripheral face of the mouth neck section 12a of the container body 12, for example.
  • the helical tube 14 which forms the helical flow path 15 as being arranged inside the cap 10 for a squeeze container is a plastic-made molded piece.
  • a cylindrical tube having a hollow circular cross-section is extended as being wound to be a coil-spring-like helical shape and an upper end attaching section 14c with two undercut lines for engagement is vertically formed as bending the upper end part radially-inward and further bending upward along a center axis part of the helical shape.
  • the helical tube 14 is formed in a state that the upper end opening 14a is upwardly opened.
  • the helical tube 14 is formed in a state that the lower end opening 14b is opened obliquely downward along a tangential direction of the helical shape.
  • the upper end attaching section 14a of the helical tube 14 is attached as being shoehorned into a lower end part of the cylindrical intermediate section 19b of the nozzle section 19 from the lower side, so that the helical tube 14 is arranged inside the peripheral wall section 10b of the cap 10 in a state of being hanged from the lower end part of the cylindrical intermediate section 19b.
  • the upper end of the helical tube 14 is communicated with the discharge opening 13 via the upper end opening 14a and the lower end opening 14b at the lower end of the helical tube 14 is opened inside the mouth neck section 12c of the container body 12.
  • the bottom face section 15a of the helical flow path 15 being bent and extended helically with the helical tube 14 forms declination continuously tilted toward the barrel section 12b of the container body 12 from the upper end of the helical tube 14 in an erected state of the squeeze container 11.
  • the cap 10 for a squeeze container of the first embodiment having the above structure, leaking and dripping of content liquid before squeezing the squeeze container 11 can be effectively prevented and favorable liquid stopping can be obtained with back suction.
  • air mixing with content liquid can be effectively prevented as well while having a compact shape which can be easily handled at the time of attaching and detaching of the cap 10.
  • the helical flow path 15 bending and extending at least a part of the liquid flow path from the mouth neck section 12a of the container body 12 to the discharge opening 13 is formed by the helical tube 14.
  • the squeeze container 11 is tilted or inverted, content liquid is discharged from the discharge opening 13 after passing through the liquid flow path bended and extended with the helical flow path 15. Accordingly, a certain amount of time is required for content liquid to pass through the bent and extended helical flow path 15 as well as smoothly discharging content liquid from the discharge opening 13 after passing through the liquid flow path.
  • the entire wall face of the helical flow path 15 is contacted with content liquid while the content liquid is discharged, that is, while the content liquid passes through the liquid flow path. Therefore, the content liquid can be held for a long time as being less likely to be replaced by air from the discharge opening 13 into the flow path. Accordingly, it is possible to effectively prevent leaking and dripping of content liquid from the discharge opening 13 owing to internal pressure of the container body 12 and self-weight of the content liquid after the discharge opening 13 is directed to a discharge position as tilting or inverting the squeeze container 11 until the barrel section 12b of the container body 12 is squeezed.

  • the bottom face section 15a of the helical flow path 15 bent and extended with the helical tube 14 is formed to have declination toward the barrel section 12b of the container body 12 in an erected state of the squeeze container 11. Therefore, even when content liquid remains in the helical flow path 15, the remaining content liquid is smoothly recovered to the barrel section 12b of the container body 12 as falling owing to self-weight along the declination of the bottom face section 15a only by placing the squeeze container 11 in an erected state after usage, for example.
  • cross-section area of the discharge opening 13 and the liquid flow path are not required to be lessened, it is possible to effectively prevent squeeze pressure from being heightened at the time when the barrel section 12b of the container body 12 is squeezed.
  • FIGS. 3 and 4 illustrate a cap 20 for a squeeze container of the second embodiment preferable for the present invention.
  • the helical flow path 15 structuring as at least a part of the liquid flow path from the mouth neck section 12a of the container body 12 to a discharge opening 13' is formed by a helical blade 21 which is arranged at a cylindrical leading path 18 oriented toward the discharge opening 13' of the cap 20.
  • the helical blade 21 is a plastic-made molded piece formed integrally with a center axis member 22.
  • a support rod 23 formed integrally with the center axis member 22 at the lower end thereof is joined to a peripheral part of a lower end opening of the cylindrical leading path 18, so that the helical blade 21 is arranged as being shoehorned into an upper part of the cylindrical leading path 18, preferably in a state that a peripheral end face of the helical blade 21 is contacted to an inner face of the cylindrical leading path 18.
  • the helical blade 21 placed in the cylindrical leading path 18 forms the bent and extended helical flow path 15 at the liquid flow path from the mouth neck section 12a of the container body 12 to the discharge opening 13' of the cap 25 via the cylindrical leading path 26. Further, the bottom face section 15a of the helical flow path 15 formed by the helical blade 21 forms declination continuously tilted toward the barrel section 12b of the container body 12 from the upper end of the helical blade 21 in an erected state of the squeeze container 11.
  • the helical flow path 15 bent and extended with the helical blade 21 is formed at at least a part of the liquid flow path from the mouth neck section 12a of the container body 12 to the discharge opening 13' and the bottom face section 15a of the helical flow path 15 with the helical blade 21 is formed to have declination in an erected state of the squeeze container 11. Therefore, similar operational effects to the cap 10 for a squeeze container of the first embodiment can be obtained.
  • the present invention may be modified variously.
  • another member may be utilized variously as the member for forming a helical flow path to be arranged at least at a part of a liquid flow path from a mouth neck section of a container body to a discharge opening.
  • an attaching plate and the like having a helical groove on an upper face thereof capable of being fitted toward the inside of a top face section of a cap.
  • the cap for a squeeze container of the present invention According to the cap for a squeeze container of the present invention, leaking and dripping of content liquid before squeezing the squeeze container can be effectively prevented and favorable liquid stopping can be obtained with back suction. In addition, air mixing with content liquid can be effectively prevented as well while having a compact shape which can be easily handled at the time of attaching and detaching of the cap.
