Description

  The present invention relates to a container.

  As a container for storing high-viscosity liquids such as shampoo (rinse, conditioner, shampoo, etc.), soaps (hand soap, body soap, etc.), a container comprising a container body and a pump dispenser having a dip tube Is widely used. In such a container, in order to prevent the content liquid from remaining in the container main body as much as possible, a notch is formed in the peripheral wall of the lower end of the dip tube so that the lower end of the dip tube reaches the bottom surface of the container main body. In many cases, a configuration is employed (for example, Patent Document 1). However, in the container, if the content liquid is to be discharged while the remaining amount of the high-viscosity content liquid is low, the air in the container body is sucked into the dip tube together with the content liquid, and the content liquid is difficult to be discharged. May be.

This will be described more specifically with the container 100 illustrated in FIG. 9 as an example. The container 100 includes a container body 110 and a pump dispenser including a dip tube 112. A notch 114 is formed in the peripheral wall at the lower end of the dip tube 112.
In the container 100, when the remaining amount of the high-viscosity content liquid L is reduced and the pump dispenser is operated with the liquid level close to the notch 114, the content liquid L is sucked into the dip tube 112 and the vicinity of the dip tube 112 On the side of the notch 114, a dent D is generated on the liquid surface. Then, the recess D reaches the notch 114 and the bubble B enters the dip tube 112. As described above, when the bubbles B enter the dip tube 112 together with the content liquid L, the pump mechanism of the pump dispenser does not sufficiently function, and the content liquid L becomes difficult to be discharged.

  As a container that prevents bubbles from entering the dip tube when discharging the content liquid with the remaining amount of liquid remaining low and the liquid level close to the notch of the dip tube, for example, a hole was opened in the center. There has been proposed a container in which a dip tube is inserted into the float and the float is slid with respect to the dip tube in the container body (for example, Patent Documents 2 and 3). In the container, the floating lid is positioned on the liquid level of the content liquid, and the liquid lid is lowered together with the liquid level as the content liquid is sucked out and the liquid level is lowered. Thereby, even when the remaining amount of the content liquid is reduced, it is possible to suppress the depression of the liquid surface when the content liquid is discharged, thereby suppressing air from being sucked into the dip tube.

Special table 2012-532809 gazette Japanese Utility Model Publication No. 58-21575 JP 2007-261680 A

  However, in a container such as Patent Documents 2 and 3, if the diameter of the hole of the lid for inserting the dip tube is not sufficiently large with respect to the outer diameter of the dip tube, the lid is caught on the outer wall of the dip tube. This makes it difficult for the lid to descend. Therefore, it is difficult to stably obtain the effect of suppressing the formation of a dent in the liquid surface when the remaining amount of the content liquid is small and the liquid surface is close to the notch portion of the dip tube. On the other hand, if the diameter of the levitation hole is increased so that the levitation can be lowered stably, air will flow around the dip tube through the hole in the dip tube when the remaining amount of liquid is low. It becomes easy to get in.

  In the present invention, when a high-viscosity content liquid is accommodated, the air in the container body is sucked into the dip tube even when the content liquid is low and the liquid level is close to the notch of the dip tube. It is an object of the present invention to provide a container that is difficult to discharge the content liquid easily.

  The container of the present invention is a container comprising a container main body for containing the content liquid, and a pump dispenser having a dip tube that sucks and discharges the content liquid in the container main body, and is cut out at the lower end of the dip tube. The dip tube has an overhanging portion extending outward from the peripheral wall of the dip tube, and is fixed to the dip tube at a position near the notch and above the notch. Covered by overhang.

  In the container of the present invention, the overhang portion may be detachably fixed to the dip tube.

  In the container of the present invention, when the high-viscosity content liquid is accommodated, the air in the container body remains in the dip tube even when the remaining amount of the content liquid is small and the liquid level is close to the notch of the dip tube. It is hard to be sucked in and it is easy to discharge the content liquid.

(Container body)
As shown in FIG. 1, the container body 10 includes a circular bottom surface portion 14 in a plan view, a cylindrical body portion 16 erected from the periphery of the bottom surface portion 14, and an annular shape extending inward from the upper end of the body portion 16. And a storage portion 20 for storing the content liquid L. In addition, a cylindrical mouth and neck portion (not shown) extending upward from the inner tip of the shoulder portion 18 is provided on the upper portion of the accommodating portion 20 in the container body 10. On the outer peripheral surface of the mouth-and-neck portion, a screw portion for screwing and mounting a mounting cap 26 of the pump dispenser 12 described later is provided.

  What is necessary is just to set the magnitude | size of the container main body 10 suitably according to a use. Moreover, in the container of this invention, the shape of a container main body is not limited to cylindrical shape like the container main body 10, The optimal shape can be suitably selected according to a use.

A known material can be used as a material for forming the container body 10, and examples thereof include synthetic resin materials such as polyethylene resin, polypropylene resin, and polyester resin.
The container body 10 may be transparent, may be colored from the viewpoint of design, and may not be able to visually recognize the contained content liquid L.

(Pump dispenser)
The pump dispenser 12 includes a nozzle head 22, a pump main body portion 24 that pumps the content liquid L to the nozzle head 22, a mounting cap 26 that is screwed onto the mouth and neck of the container main body 10, and the pump main body portion 24. A cylindrical dip tube 28 and an overhanging portion 30 fixed in the vicinity of the lower end of the dip tube 28 are provided.

The nozzle head 22 includes a head portion 22a having a circular shape in plan view, and a nozzle portion 22b extending outward from the outer peripheral surface of the head portion 22a.
The head portion 22a is a portion that is pressed downward by the user. Inside the head portion 22a, a flow path (not shown) that guides the content liquid L pumped by the pump body portion 24 described later to the nozzle portion 22b is provided. The nozzle portion 22b is a portion that discharges the content liquid L from the tip. The flow path inside the nozzle portion 22b communicates with the flow path of the head portion 22a.

  The mounting cap 26 is a portion that is screwed onto the mouth and neck of the container body 10. On the inner peripheral surface of the mounting cap 26, a screw portion that is screwed with a screw portion provided on the outer peripheral surface of the mouth / neck portion of the container body 10 is provided. The pump cap 12 is detachably mounted on the mouth / neck portion of the container body 10 by screwing the mounting cap 26 onto the mouth / neck portion of the container body 10.

  In this example, a screw portion 26 a is provided on the outer peripheral surface of the upper portion of the mounting cap 26, and a screw portion that is screwed with the screw portion 26 a is formed on the inner peripheral surface of the outer wall portion of the head portion 22 a of the nozzle head 22. Thus, the container 1 can be fixed by being screwed into the mounting cap 26 in a state where the nozzle head 22 is pushed down when not in use. At the time of use, by releasing this screwing, a later-described stem 32 is pushed upward by an urging force.

The pump main body portion 24 is a portion that pumps the content liquid L stored in the container main body 10 to the nozzle portion 22b when the head portion 22a of the nozzle head 22 is pushed down. The pump body 24 includes a stem 32 that extends upward from the mounting cap 26 and is supported so as to be movable in the vertical direction, and a cylinder 34 that is suspended from the lower surface of the mounting cap 26.
A head portion 22 a of the nozzle head 22 is attached to the upper end portion of the stem 32. Further, the stem 32 is urged upward, and the head portion 22a can be pushed down against this urging force.

The cylinder 34 forms a pump chamber filled with the content liquid, and has a suction port (not shown) for sucking the content liquid L stored in the container body 10 at its lower end, and the suction port. A spherical valve body that opens and closes is provided. The valve body opens the suction port only when a negative pressure is generated in the cylinder 34 by the expansion operation of the pump chamber.
A vent hole (not shown) for introducing air into the container main body 10 is provided in a portion of the cylinder 34 located near the mouth and neck in the container main body 10. A compression coil spring (not shown) that biases the stem 32 upward and a piston (not shown) attached to the lower end of the stem 32 are provided in the cylinder 34. . The piston plays a role of pressure-feeding the content liquid L pressurized in the cylinder 34 to the nozzle head 22 side through the stem 32 while being in sliding contact with the inner surface of the cylinder 34.

  As shown in FIGS. 1 and 2, the dip tube 28 is suspended from the lower end portion of the cylinder 34 to the bottom surface portion 14 of the container body 10. The flow path in the dip tube 28 is connected to the suction port of the cylinder 34. The dip tube 28 is preferably drooped linearly toward the bottom surface 14 of the container body 10.

On the peripheral wall at the lower end of the dip tube 28, a notch 28a serving as a suction port for the content liquid L is formed.
Since the notch portion 28a is formed at the lower end portion of the dip tube 28, the content liquid L enters the dip tube 28 from the notch portion 28a even when the lower end portion of the dip tube 28 is in contact with the bottom surface portion 14 of the container body 10. Can inhale. Further, the cutout portion 28a formed at the lower end portion of the dip tube 28 that hangs down to the bottom surface portion 14 of the container body 10 is difficult to be exposed from the content liquid L even if the content liquid L decreases. Therefore, the remaining amount of the content liquid L is small, and it becomes easy to discharge the content liquid L even when the liquid level is close to the notch 28 a of the dip tube 28.

The front view shape of the notch 28a is not particularly limited, and examples thereof include a semicircular shape and a rectangular shape.
What is necessary is just to set the magnitude | size of the notch part 28a suitably according to the viscosity etc. of the content liquid L. FIG. For example, the distance from the lower end of the dip tube to the upper end of the notch 28a is 1 to 10 mm.

1 to 3, the dip tube 28 has a dip tube that is close to the notch 28a and above the notch 28a in a direction in which the notch 28a faces the center axis of the dip tube 28. A flat plate-like projecting portion 30 projecting outward from the peripheral wall 28 is fixed. In the present invention, the fact that the overhanging portion is fixed means that the overhanging portion is fixed at least to the extent that the overhanging portion does not move in the axial direction of the dip tube due to the movement of the content liquid during discharge or the like. .
Since the overhang portion 30 is fixed, the cutout portion 28 a is covered with the overhang portion 30 in plan view. Such an overhang portion 30 is in a state of being immersed in the content liquid L at the time of use. By providing the overhanging portion 30, even when the content liquid L is discharged in a state where the remaining amount of the high-viscosity content liquid L is small and the liquid surface is close to the notch portion 28 a, It becomes difficult to be sucked into the dip tube 28 and the content liquid L can be easily discharged.

  The planar view shape of the overhang portion 30 in this example is substantially elliptical. In the present invention, the planar view shape of the overhanging portion is not limited to a substantially elliptical shape, and can be appropriately selected according to the cross-sectional shape of the trunk portion of the container body. Specifically, the planar shape of the overhang portion may be a semicircular shape, a circular shape, a rectangular shape, or the like.

  In addition, the angle formed between the overhang portion 30 and the center axis of the dip tube 28 is 90 ° in this example. The angle formed between the overhang portion 30 and the central axis of the dip tube 28 may not be 90 ° as long as the air in the container body can be suppressed from being sucked into the dip tube.

  The distance d1 (FIG. 2) from the upper end of the notch 28a to the overhang 30 and the distance d2 (FIG. 2) from the outer peripheral surface of the dip tube 28 to the tip of the overhang 30 can provide the effects of the present invention. What is necessary is just to set suitably according to the viscosity etc. of the content liquid L within the range. Further, the width d4 (FIG. 3) of the overhang portion 30 may be appropriately set according to the viscosity of the content liquid L and the like within a range in which the effect of the present invention is obtained. The width of the overhang portion 30 means the maximum value in the length in the direction perpendicular to the direction from the base end on the dip tube 28 side to the tip end of the overhang portion 30.

  As a specific example, when the viscosity of the content liquid L is 1 Pa · s to 30 Pa · s at 25 ° C., for example, the distance d1 from the upper end of the notch 28 a to the overhang 30 is 0 to 5 mm, the dip tube 28 The aspect from which the distance d2 from the outer peripheral surface of this to the front-end | tip of the overhang | projection part 30 is 3-20 mm, and the width | variety d4 of the overhang | projection part 30 is 10-50 mm etc. are mentioned. In this aspect, by making the distance d1, the distance d2, and the width d4 within the above ranges, the air in the container body 10 is easily suppressed from being sucked into the dip tube 28.

  In addition, when the overhanging portion 30 does not have elasticity, the size of the overhanging portion 30 is set to open the mouth and neck of the container main body 10 in order to put the dip tube 28 and the overhanging portion 30 in the container main body 10. It is necessary to make it smaller than the aperture. In the case where the overhanging portion 30 is formed of rubber or the like and the overhanging portion 30 has elasticity, the overhanging portion 30 has a size within a range where the dip tube 28 and the overhanging portion 30 can be placed in the container body 10. The thickness may be larger than the opening diameter of the mouth and neck of the container body 10.

  The distance d3 (FIG. 2) between the tip of the overhang portion 30 and the inner wall surface of the trunk portion 16 may be set as appropriate according to the viscosity of the content liquid L and the like. As in this example, in the embodiment in which the overhanging portion 30 is provided toward the side where the notch 28a is formed in the dip tube 28 and there is no overhanging portion on the opposite side, the tip of the overhanging portion 30 is the trunk portion. You may be in contact with 16 inner wall surfaces.

The material for forming the nozzle head 22, the pump main body 24, the mounting cap 26, and the dip tube 28 in the pump dispenser 12 is not particularly limited, and known materials that are commonly used for pump dispensers can be employed. For example, synthetic resin materials such as polyethylene resin, polypropylene resin, and polyester resin can be used.
As a material for forming the overhanging portion 30, any material that can suppress the air in the container body 10 from being sucked into the dip tube 28 may be used. For example, a synthetic resin material such as a polyethylene resin, a polypropylene resin, or a polyester resin is used. Is mentioned. The overhang portion 30 may be formed of an elastic material such as rubber.

(Production method)
The manufacturing method of the container main body 10 is not specifically limited, Blow molding etc. are mentioned. The manufacturing method of the pump dispenser 12 is not specifically limited, A well-known method is employable.
In the present invention, the overhanging part may be formed integrally with the dip tube, or may be formed separately from the dip tube and attached to the dip tube and fixed detachably. The aspect in which the overhanging part is detachably attached to the dip tube is advantageous in that the overhanging part can be attached and fixed to the dip tube manufactured by existing equipment.

(Content liquid)
Although the content liquid accommodated in the container of the present invention is not particularly limited, the present invention is particularly useful when accommodating a highly viscous content liquid. Specifically, it is particularly useful when containing a content liquid having a viscosity of 1 Pa · s to 30 Pa · s under 25 ° C conditions.
Specific examples of the content liquid include high-viscosity cosmetic liquids such as shampoos (rinse, conditioner, shampoo, etc.), soaps (hand soap, body soap, etc.), detergents, liquid detergents, softeners, liquids For example, toothpaste.

(Function and effect)
Hereinafter, the operation of the container 1 will be described.
In the unused state, the mounting cap 26 is screwed onto the mouth and neck of the container body 10 while the content liquid L is stored in the container 20 of the container body 10, so that the pump dispenser 12 can be The main body 10 is detachably mounted. In this state, the lower end of the dip tube 28 is in contact with the bottom surface portion 14 of the container body 10.
Further, when the nozzle head 22 is pushed down, the nozzle head 22 is screwed and fixed to the upper portion of the mounting cap 26. When the container 1 is used, the screwing between the nozzle head 22 and the mounting cap 26 is released. Thereby, as shown in FIGS. 1 and 2, the nozzle head 22 is pushed upward together with the stem 32 by the urging force.

  When discharging the content liquid L, the nozzle head 22 is pushed down against the urging force. As a result, the piston descends and the content liquid L filled in the cylinder 34 is pressurized, and is pumped to the nozzle head 22 through the stem 32, and the content liquid L is discharged from the tip of the nozzle portion 22b. When the pressure on the nozzle head 22 is released, the pressed nozzle head 22 rises together with the stem 32, and the valve element opens the suction port by the negative pressure generated in the cylinder 34. Thereby, the content liquid L accommodated in the container main body 10 is sucked into the dip tube 28 from the cutout portion 28a and refilled into the cylinder 34. At this time, as the content liquid L in the container body 10 decreases, external air is introduced into the container body 10 through the vent holes.

  In the container 1, the overhang portion 30 is fixed to the side where the notch portion 28 a is formed at the lower end portion of the dip tube 28. Therefore, when the content liquid L is discharged in a state where the remaining amount of the high-viscosity content liquid L is small and the liquid level is close to the notch 28a, as shown in FIG. Occurs in the vicinity of 30 outer peripheral ends. As described above, in the container 1, when the remaining amount of the content liquid L decreases, the liquid level depression D is far from the notch 28 a of the dip tube 28 compared to the case where the overhang portion 30 is not provided. Occur. Therefore, even when the nozzle head 22 is completely pushed down, the air in the container body 10 hardly reaches the notch 28a of the dip tube 28, and the air in the container body 10 is suppressed from being sucked into the dip tube 28. The Thereby, the remaining amount of the high-viscosity content liquid L is small, and it is easy to discharge the content liquid L even in a state where the liquid level is close to the notch 28a.

  As described above, in the container of the present invention, the remaining amount of the high-viscosity content liquid is small and the liquid level is notched due to the overhang provided near the notch in the dip tube and above the notch. Even when the content liquid is discharged in a state close to, the air in the container body is not easily sucked into the dip tube, and it is easy to discharge the content liquid.

The container of the present invention is not limited to the container 1 described above.
For example, the container of the present invention may be the container 2 illustrated in FIGS. 5 and 6, the same parts as those in FIGS.
The container 2 is provided with a circular protruding portion 30A that protrudes outward over the entire circumference of the peripheral wall of the dip tube 28 above the notch 28a near the lower end of the dip tube 28, instead of the protruding portion 30. It is the same as the container 1 except being described.

  In the container 2, the distance d3 (FIG. 6A) between the tip of the overhanging portion 30A and the inner wall surface of the trunk portion 16 is preferably 5 mm or more within a range in which the effect of the present invention can be obtained. As a result, the content liquid L existing above the overhanging portion 30A in the container main body 10 is projected from between the tip of the overhanging portion 30A and the inner wall surface of the trunk portion 16 when the content liquid L is discharged. It becomes easy to move to the lower side, and it becomes easy to discharge the content liquid L smoothly.

  In the container 2, as in the case of the container 1, even when the remaining amount of the high-viscosity content liquid L is small and the liquid surface is close to the cutout portion 28 a, Since the air in 10 is suppressed from being sucked into the dip tube 28, the content liquid L can be easily discharged.

The container of the present invention may be the container 3 illustrated in FIG. 7, the same parts as those in FIGS. 2 and 3 are denoted by the same reference numerals, and the description thereof is omitted.
The container 3 is the same as the container 1 except that an overhang part 30 </ b> B is provided instead of the overhang part 30. The overhanging portion 30B projects outward from the peripheral wall of the dip tube 28, and has a flat plate-like overhanging piece 30a having the same form as the overhanging portion 30 and a cylindrical shape suspended from the inner peripheral edge of the overhanging piece 30a. It is the same as the overhang portion 30 except that the tube portion 30b is provided.
The overhanging portion 30B is formed as a separate member from the dip tube 28, and can be attached and fixed near the lower end portion of the dip tube 28 by being inserted into the lower end portion of the dip tube 28. It has become.

  In the container 3, as in the container 1, even when the remaining amount of the high-viscosity content liquid L is small and the liquid surface is close to the notch portion 28 a, Since the air in 10 is suppressed from being sucked into the dip tube 28, the content liquid L can be easily discharged.

Moreover, in the container of this invention, the notch part notched diagonally from one side of the surrounding wall to the opposite side may be formed in the lower end part of a dip tube.
Specifically, for example, as shown in FIG. 8, a notch portion 28 b that is obliquely cut from one side of the peripheral wall to the opposite side is formed at the lower end portion of the dip tube 28. The container 4 to which the circular protruding portion 30A is fixed so as to cover 28b may be used. 8 that are the same as those in FIG. 6A are given the same reference numerals, and descriptions thereof are omitted.
Also in the container 4, as in the case of the container 1, even when the remaining amount of the high-viscosity content liquid L is small and the liquid surface is close to the notch portion 28b, Since the air in 10 is suppressed from being sucked into the dip tube 28, the content liquid L can be easily discharged.
