Definitions

  • the present invention relates to a liquid pouring member and a container.
  • a generally employed container has a nozzle attached to a plug fitted to an opening of a container that contains liquid such as liquid medicine so as to be poured to the diseased part. After pouring the liquid, the nozzle is capped. There may be the case that when removing the cap for the subsequent use of the container, the liquid remaining on the inner wall surface of the nozzle is extruded under the internal pressure higher than the external pressure, causing accidental sprouting from the nozzle.
  • the plug fitted to the disclosed squeeze container includes a mount fitting cylinder 3 to be internally fitted to the neck portion 2 of the container 1, a straight cylindrical nozzle 5 disposed while projecting from the mount fitting cylinder 3 substantially vertically upward, and an outlet hole 4 penetrating through the nozzle 5.
  • the lower end of the nozzle 5 is formed as an inclined plane marked by substantially T-like symbol.
  • Each of the nozzle 5 and the outlet hole 4 of the plug in the description of PTL 1 is substantially vertically thin and long shaped.
  • the liquid adheres to the inner wall surface of the outlet hole 4 as foam when pouring the liquid
  • external air flowing into the container 1 through the outlet hole 4 after pouring the liquid forces the foam to fall down to the lower end of the nozzle 5.
  • the foam falling down to the lower end of the nozzle 5 easily drops into the container 1 along the inclined plane marked by substantially T-like symbol of the lower end of the nozzle 5. This may prevent the liquid that has adhered to the inner wall surface of the outlet hole 4 and the nozzle 5 from being kept remained. Accordingly, the remaining foam-like liquid is never extruded from the outlet hole 4 when removing the cap 8 in the subsequent pouring.
  • the present invention has been made in consideration of the above-described circumstances, and it is an object of the present invention to provide a liquid pouring member and a container, capable of effectively preventing the liquid from spouting upon opening.

  • the nozzle lower part includes a column portion vertically extending from the lower surface of the base, and the column portion includes a side surface and a bottom surface from which the end portion extends.
  • the bottom surface has the same height as an edge of the skirt.
  • the constriction is formed from a position at the same height as the bottom surface to an inner side of the column portion.
  • an edge portion as an intersection between the side surface and the bottom surface forms an angular portion at an angle of 90°.
  • the end portion may include a convex portion axially extending along a side surface of the radially narrow portion for guiding falling droplets.
  • the convex portion radially protrudes in a range not in excess of a diameter of the column portion.
  • the nozzle lower part according to another preferred embodiment extends up to the end portion without a stepped portion.
  • the structure having the radially wide and narrow portions may be formed by the means (1) to (3) to be described below, for example.
  • a length of the inner passage from the constriction to the outlet port is equal to or longer than 5 mm.
  • the base includes a top having the upper surface and the lower surface, and a side wall extending downward from the top.
  • a thread may be formed on an inner surface of the side wall for threaded engagement with a thread formed over an outer circumference of a side surface of the opening of the container.

  • the inner passage 9 includes a constriction 20 with its sectional area of a passage smaller than that of the other part.
  • the constriction 20 is formed at the lower position closer to the end portion 11. More preferably, the constriction 20 is formed into the column portion 10 from the position at the same height as the bottom surface 25.
  • the length of the inner passage 9 between the constriction 20 and the outlet port 7 is as long as possible, for example, equal to or longer than 5 mm, and more preferably, equal to or longer than 10 mm.
  • the nozzle lower part 6 extends downward from the position on the lower surface 17 biased from the center of the skirt 4, thus forming a radially wide portion 22 and a radially narrow portion 23.
  • the nozzle upper part 5 also extends from the biased position on the upper surface 16 of the base 3 in alignment with the nozzle lower part 6.
  • the inclined surface 12 of the end portion 11 of the nozzle lower part 6 is directed to the wide portion 22.
  • the inclined surface 12 may be directed to the narrow portion 23, for example, or arbitrarily directed without the present invention being limited to the one as described above (applicable to the other embodiment).
  • the base 3 includes a top 14 having the upper surface 16 and the lower surface 17, and a side wall 15 extending downward from the top 14.
  • a thread 18 is formed on an inner surface of the side wall 15 for threaded engagement with a thread formed over an outer circumference of a side surface of the opening of the container.
  • a thread 19 is formed over an outer circumference of the side surface of the nozzle upper part 5.
  • a liquid drip-off portion 21 is formed over the outer circumference of an end portion of the nozzle upper part 5.

  • Fig. 3 shows a state in which the inner plug 1 as shown in Fig. 1 is fitted to a container 40, and the cap 30 as shown in Fig. 2 covers the inner plug 1.
  • a thread 42 is formed over an outer circumference of the side surface of an opening 41 of the container 40.
  • the thread 18 of the inner plug 1 is threadedly engaged with the thread 42 of the container so that the skirt 4 of the inner plug 1 is fitted to the inside of the open space of the opening 41 of the container 40. Accordingly, the inner plug 1 may be fitted to the container 40.
  • Threadedly engaging the thread 31 of the cap 30 with the thread 19 of the nozzle upper part 5 allows attachment of the cap 30 to the inner plug 1.
  • the protrusion 33 of the cap 30 is inserted into the outlet port 7 of the nozzle 2. Accordingly, there is no risk that the liquid content of the container 40 leaks outside while the cap 30 is attached to the inner plug 1. Furthermore, air-tightness in the container may be retained.

  • the outlet port 7 is closed with the protrusion 33 of the cap 30, air remains in the inner passage 9. Because of the resultant air pressure, the liquid content 44 that has reached the constriction 20 remains in the inner passage near the constriction 20 and the inlet port 8.
  • the end portion 11 having the inlet port 8 protrudes downward farther than the edge of the skirt 4. Furthermore, as the angular portion 13 at an angle of 90° is formed, the liquid content to be gathered around the inlet port 8 under the capillary attraction may be minimized.
  • the extruded liquid content splashes before reaching the outlet port 7 while passing through the long inner passage 9 as indicated by a reference numeral 47. Then air in the container is communicated with outside air to bring the pressure into the ordinary state.
  • the liquid content gathered in the radially narrow portion 23 falls down by its own weight. Even if a small amount of the liquid content remains, the remaining liquid is reduced from the portion around the inlet port 8 upon removal of the cap 30 because of the end portion 11 having the inlet port 8 protruding downward farther than the edge of the skirt 4, and the angular portion 13 at an angle of 90°. This makes it possible to effectively prevent spouting of the remaining liquid upon removal of the cap.
  • the embodiment prevents the liquid content from spouting as a result of detaching the cap 30.
