Description

  The present invention includes a container main body for storing the content liquid, a topped cylindrical pouring cap attached to the mouth of the container main body, and a closing plug for closing the pouring outlet provided on the top wall of the pouring cap. The present invention relates to a dispensing container that has a lid body and that dispenses the content liquid contained in the container main body from a spout, and particularly relates to a liquid that contains a relatively high viscosity liquid such as olive oil as the content liquid.

  As a container for storing the content liquid, a pouring cap is attached to the mouth portion of the container main body for storing the content liquid, and a desired amount of liquid can be easily poured out from the spout provided in the pouring cap. Such a dispensing container is known.

  Usually, the spout is formed in a cylindrical shape protruding from the top wall of the spout cap, and the spout cap is provided with a lid for closing the spout formed in the cylindrical shape. In general, the lid body is attached to the pouring cap so as to be freely opened and closed by, for example, a hinge, and on the back surface thereof, a closing plug that is inserted into the pouring port and closes the pouring port is provided. Therefore, if liquid remains in the spout after the content liquid is poured out, there is a risk that when the lid is closed, the liquid is pushed out of the spout by the closing plug and scattered on the back surface of the lid, etc. is there.

  Therefore, for example, in the pouring container shown in Patent Document 1, the top wall where the pouring outlet of the pouring cap is provided is connected to the lower end of the cylindrical pouring outlet and protrudes from the top wall into the container body. Thus, the liquid level of the liquid remaining inside the spout after the content liquid is poured is lowered to prevent the liquid from splashing outside when the lid is closed.

The shape and size of the spout 23 is the container body 10. Various changes can be made according to the contents, usage, etc. accommodated in the container. The spout 23 is not limited to a cylindrical shape protruding from the term wall 21, but can be formed as a hole that penetrates the term wall 21 but does not protrude from the top wall 21.

  The lid body 30 is formed in a cylindrical shape with the same diameter as the pouring cap 20, and is connected to the pouring cap 20 through a hinge H at a part of the outer peripheral surface thereof so as to be freely opened and closed. The lid 30 has a locking groove 31 provided on the inner periphery of the opening edge thereof undercut-engaged with a locking projection 21 a provided on the outer peripheral edge of the top wall 21, whereby the top wall of the dispensing cap 20. 21 is covered, that is, in a closed state. Further, a cylindrical plug 32 is integrally provided on the back surface of the lid 30. When the lid 30 is closed, the plug 32 is fitted to the inner peripheral surface of the spout 23 and is spouted. 23 is closed. On the other hand, a hook-shaped knob 33 projecting radially outward is integrally provided at a portion of the outer peripheral surface of the lid 30 opposite to the hinge H, and the hinge 33 is lifted by lifting the knob 33. The spout 23 can be opened by turning the lid 30 away from the pouring cap 20 around H.

  The inner plug 40 is attached to the opening end of the mouth portion 11 and covers the opening end. A cylindrical engaging wall 41 that stands upward is integrally provided on the outer peripheral edge of the inner plug 40, and the upper end of the engaging wall 41 abuts on the lower surface of the top wall 21 of the dispensing cap 20. ing. Thereby, a predetermined space is provided between the inner plug 40 and the top wall 21.

  As shown in FIGS. 1 and 2, the inner plug 40 is provided with an outflow hole 42 for the content liquid. The outflow hole 42 communicates with the spout 23 through a space between the inner plug 40 and the top wall 21, and the content liquid stored in the container body 10 is directed to the spout 23 through the outflow hole 42. Can be leaked. In the present embodiment, the outflow hole 42 is provided at a position shifted to the hinge H side with respect to the spout 23.

  As shown in FIG. 1, the check valve 50 is formed in a plate shape (disc shape) and is disposed on the upper surface of the inner plug 40 facing the top wall 21 side to close the outflow hole 42. An annular wall 51 is disposed between the top wall 21 and the inner plug 40, and the check valve 50 is connected to the annular wall 51 by a plurality of elastically deformable legs 52. As a result, the check valve 50 can move in a direction approaching and separating from the upper surface of the inner plug 40 to open and close the outflow hole 42.

  The space between the top wall 21 and the inner plug 40 is partitioned into a liquid channel on the inner side of the annular wall 51 and a gas channel on the outer side of the annular wall 51.

  The inner plug 40 is provided with a cylindrical tubular wall 43 that is located on the side opposite to the hinge H with respect to the outflow hole 42 and extends toward the inside of the container body 10. Further, a reduced diameter portion 43a whose inner diameter becomes narrower toward the lower side is provided at the lower end of the cylindrical wall 43. Inside the cylindrical wall 43, a valve body 44 formed in a spherical shape (ball) with a steel material, resin, or the like is disposed. When the container body 10 is in an inclined posture with the cylindrical spout 23 facing downward, the valve body 44 moves toward the spout 23 in the cylindrical wall 43. When the container body 10 is returned to the upright posture (upright posture) so that the cylindrical spout 23 faces upward after the content liquid is poured out, the valve body 44 moves through the inside of the cylindrical wall 43. The liquid content that moves downward until it comes into contact with the reduced diameter portion 43 a and remains in the spout 23 is sucked toward the inside of the cylindrical wall 43. Thereby, the remaining amount of the liquid inside the spout 23 can be reduced and the dripping from the spout 23 can be prevented. Thus, the valve body 44 functions as a suck back mechanism for preventing liquid dripping from the spout 23.

  The lower end of the mounting cylinder portion 22 of the dispensing cap 20 is airtightly fitted to the lower portion of the mouth portion 11 of the container body 10, whereby an air flow path is provided between the mouth portion 11 and the mounting tube portion 22.

  On the other hand, an opening 24 is provided in the top wall 21 of the dispensing cap 20, and this opening 24 is provided with an air flow through a through hole 45 provided in a connection portion between the inner plug 40 and the engaging wall 41. It communicates with the road P. The male screw 11a is provided with a slit S that constitutes a part of the air flow path P.

  An air check valve 53 that opens and closes the opening 24 is integrally provided outside the annular wall 51. The air check valve 53 functions to permit the introduction of outside air from the opening 24 to the air flow path P and to block the flow of air from the air flow path P to the opening 24. Therefore, when squeezing the trunk portion 12 of the container body 10 to pour out the content liquid, the content liquid is easily pushed out from the inner layer body 14 by holding air between the outer layer body 13 and the inner layer body 14. Can do. When the squeeze of the body portion 12 is released after the content liquid is poured out, the outside air is introduced between the outer layer body 13 and the inner layer body 14 through the opening 24, the air flow path P, and the outside air introduction port 15, and the inner layer body 14 The portion corresponding to the body portion 12 of the outer layer body 13 can be restored to the original shape while the volume is reduced and deformed. This prevents the outside air from flowing into the inner layer body 14 from the spout 23 with the restoration of the barrel 12 after the content liquid is poured out, and the contents contained in the inner layer body 14 are turned into air. It is difficult to touch and deterioration of the quality can be suppressed.

  A cylindrical portion 60 is integrally provided on the lower surface of the top wall 21 of the dispensing cap 20. The cylindrical portion 60 is connected to the lower end of the cylindrical spout 23 to form a flow path for discharging the content liquid together with the spout 23. The cylindrical portion 60 protrudes from the top wall 21 into the container body 10, that is, toward the space between the top wall 21 and the inner plug 40, and its lower end has a predetermined interval with the check valve 50. They are facing each other.

  As shown in FIG. 3A, a tapered portion 61 that increases in diameter toward the lower end of the cylindrical portion 60 is provided on the lower end side of the inner peripheral surface of the cylindrical portion 60. The tapered portion 61 has an inclination angle of 45 degrees with respect to the axial direction of the cylindrical portion 60, for example, but can be appropriately selected depending on the contents. The taper portion 61 reaches the outer peripheral surface of the cylindrical portion 60, but may be configured not to reach the outer peripheral surface.

  In addition, a stepped portion 62 is provided in a part of the lower end of the cylindrical portion 60 in the circumferential direction by notching the lower end of the cylindrical portion 60 in a stepped shape. In the illustrated case, the stepped portion 62 is provided in a range of 180 degrees in the circumferential direction on the side opposite to the side on which the hinge H at the lower end of the cylindrical portion 60 is provided, and is recessed upward with respect to the lower end of the cylindrical portion 60. It has a shape. As shown in FIG. 3 (b), the stepped portion 62 includes a flat surface 62 a perpendicular to the axial center of the cylindrical portion 60 and a pair of inclined surfaces 62 b that connect both circumferential ends of the flat surface 62 a to the lower end of the cylindrical portion 60. It is a shape with.

  Thus, by forming the lower end of the cylindrical portion 60 provided coaxially with the cylindrical spout 23 into a shape having the tapered portion 61 and the stepped portion 62, the content liquid is relatively viscous such as olive oil. Even when a high liquid is contained, when bubbles are generated inside the spout 23 or immediately below the cylindrical portion 60 after the content liquid is poured out, the bubbles are allowed to escape upward from the cylindrical portion 60 and the spout 23. Thus, bubbles can be prevented from remaining inside the spout 23. That is, by providing the tapered portion 61 on the inner peripheral surface on the lower end side of the cylindrical portion 60, it is easy for air bubbles directly below the cylindrical portion 60 to enter the cylindrical portion 60, and the stepped portion 62 is provided at the lower end of the cylindrical portion 60. By providing the liquid, the liquid inside the spout 23 and the cylindrical portion 60 can be easily discharged downward from the cylindrical portion 60 while replacing the bubbles with bubbles, and the liquid level of the liquid remaining inside the spout 23 can be lowered. Thereby, it can prevent that the liquid level inside a pouring cylinder becomes high with the bubble which remains inside the spout 23, and can prevent that a liquid splashes when closing the cover body 30. FIG. Further, by providing the stepped portion 62, even when the check valve 50 comes into contact with the lower end of the cylindrical portion 60 when the content liquid is poured out, the content liquid can be circulated through the stepped portion. It is possible to suppress a decrease in usability.

  4A to 4G are cross-sectional views showing the configuration of a cylindrical portion of a comparative example in which bubbles cannot be discharged from the inside of the dispensing cylinder.

  The present inventors examined various shapes of cylindrical portions 70 as the cylindrical portion 70 of the comparative example of the cylindrical portion 60 of the present invention. 4A is a configuration of a comparative example in which the cylindrical portion 70 is not provided with a tapered portion or a stepped portion, FIG. 4B is a configuration of a comparative example in which only the tapered portion is provided in the cylindrical portion 70, and FIG. 4 is a comparative example in which the cylindrical portion 70 is not provided at the lower end of the spout 23, and FIG. 4D is a comparative example in which the cylindrical portion 70 is not provided with a tapered portion and only a U-shaped stepped portion is provided. (E) is a configuration of a comparative example in which a cylindrical portion 70 is not provided with a tapered portion and only a step portion having a front cut shape is provided. FIG. 4 (f) is a cylindrical portion 70 which is not provided with a tapered portion. FIG. 4G shows the configuration of the comparative example in which the lower end of the cylindrical portion 70 is cut obliquely. However, in any of the comparative examples shown in FIGS. 4A to 4G, after the content liquid is poured out, the air bubbles inside the spout 23 or directly below the cylindrical portion 70 are removed from the cylindrical portion 70 and the spout 23. It was not possible to escape upward, and the effect as in the present invention could not be obtained.

  It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.

  For example, the container body 10 is not limited to a double container, and a normal container can also be used. In this case, the dispensing cap 20 can be configured without the check valve 50, the opening 24, and the air check valve 53.
