Description

  The present invention relates to a liquid container including a container main body that stores liquid and a liquid discharge device that is used by being mounted on the container main body, and a liquid product stored in the liquid container. It is related with the container for liquids which was easy to receive and was excellent in the usability which received the discharged liquid by hand.

  As containers for storing liquids such as shampoos, body soaps, hand soaps, and detergents, there are known bottle containers in which a liquid discharge device such as a push-type pump dispenser is attached to the mouth of a container body. In a bottle container equipped with a liquid ejection device, generally, when the head is pushed downward, the liquid contained in the container body is ejected from the nozzle.

In recent years, liquid products used in bottle containers equipped with liquid ejection devices have been sold as refill / refill liquid products in refill pouches in order to save resources and reduce costs. Yes.
As a pouch for refilling, two side wall films and a bottom wall film are overlapped, and a peripheral part thereof is laminated by heat welding or the like to form a bag-like bag body, and a part of the upper side of the bag body In general, a cut-out type spout is integrally formed at the top corner or the like.
However, in such a refilling pouch, there is a problem that it takes a lot of time or liquid easily spills when pouring the content liquid into the container in which the liquid ejection device is mounted. It has been required to improve the performance.

In order to solve the problem of liquid spilling during refilling, there is a refilling pouch with an improved spout. As a refillable pouch having an improved spout, a projecting spout provided at the upper corner is widely known. In addition, a technique has been proposed in which a reinforcing mechanism is provided at a spout of a refill pouch or a liquid conduit having a convex cross section is provided.
However, in refillable pouches that have improved these spouts, it is necessary to make the spouts of the refillable pouches narrower to match the caliber of the bottle-like container in order to prevent liquid from spilling, and refilling takes time. The problem could not be solved sufficiently.

Moreover, as a means for solving the above problems, a container with a pump dispenser in which the diameter of the bottle container is enlarged has been proposed (for example, Patent Document 1 and Patent Document 2).
Patent Document 1 discloses a liquid container in which a pump means having a large-diameter screwing portion that is screwed into a wide-mouthed mouth portion is attached to a bottle-like container, or a large-diameter screwing screwed into a wide-mouthed mouth portion. A liquid container is described in which pump means are attached to a bottle-like container via a joint cap with a part.
Patent Document 2 discloses a vertical pump for mounting a wide-mouth bottle provided with a holding member that allows a smaller-sized vertical pump to be attached to the neck of the wide-mouth bottle.
In the techniques described in Patent Document 1 and Patent Document 2, the ease of pouring the content liquid from the refill pouch into the bottle is improved as compared with the conventional bottle.
WO2002 / 032777 Japanese Patent Laid-Open No. 2002-159891

  However, in the techniques described in Patent Document 1 and Patent Document 2, since the bottle joint to which the pump unit is attached becomes larger as the bottle diameter increases, the liquid when the liquid is discharged using the pump unit. There was a problem that usability such as ease of removal decreased. In particular, in a small-capacity bottle container, the expansion of the pump joint due to the large diameter of the bottle container has a significant effect on the usability of the bottle container, and the problem is that the usability is reduced.

More specifically, in a liquid container to which a pump means having a large-diameter screwing portion that is screwed into a wide-mouthed portion described in Patent Document 1 is attached, the pump is compared with the bottle-shaped container. Since the head portion of the means is small, the nozzle tip is located near the joint between the bottle-shaped container and the pump means. For this reason, when the pump means is used, there is a problem that it is difficult to use because the hand that takes the discharged liquid hits the outer periphery of the holding member that joins the bottle-shaped container and the pump means.
Moreover, in the liquid container which has a joint cap provided with the large diameter screwing part screwed in the opening part of the wide mouth described in patent document 1, the diameter of a nozzle head is a junction part of a bottle-shaped container and a pump means. Is equal to the diameter. In a normal bottle with a pump dispenser, the horizontal position of the tip of the nozzle is inside the horizontal position of the outer periphery of the bottle. This is because if the horizontal position of the tip of the nozzle is outside the horizontal position of the outer periphery of the bottle, the tip of the nozzle comes into contact with each other and easily breaks during distribution. Therefore, if the diameter of the nozzle head is made equal to the diameter of the joint between the bottle-shaped container and the pump means, it is necessary to reduce the length of the nozzle. However, when the length of the nozzle is short, the liquid discharged from the bottle-shaped container is discharged to the end of the palm, which causes a problem that the discharged liquid easily spills from the hand. In particular, when a large nozzle head is adopted for a small-capacity bottle-shaped container, the nozzle becomes relatively short, and thus the above problem becomes significant.

  Moreover, in the technique described in Patent Document 2, when the pump is pushed down, the holding member is positioned in the vicinity of the nozzle tip. For this reason, in the technique described in Patent Document 2, when the pump is pushed down to discharge the liquid, the hand that receives the discharged liquid collides with the outer periphery of the holding member, and the discharged liquid is discharged to the end of the palm. Therefore, there is a problem that the discharged liquid is easily spilled from the hand and is difficult to use.

As described above, a container with an enlarged bottle container diameter is known, but it is excellent in workability for refilling work from a refill pouch and excellent in usability when discharging content liquid. The container has not yet been proposed.
The present invention has been made in view of the above points, is excellent in workability of refilling work from a refill pouch, and is easy to receive the discharged liquid by hand when the liquid is discharged. An object of the present invention is to provide an excellent liquid container.

In order to solve the above problems, the liquid container of the present invention employs the following configuration.
That is, the liquid container of the present invention is a liquid container including a container main body that stores liquid and a liquid discharge device that is used by being mounted on the container main body, and the liquid discharge device includes the container main body. A bottle joint that is detachably attached to the mouth of the head, a head provided with a nozzle, and a nozzle head supported so as to be movable in the vertical direction while being biased upward; and depressing the head And a pump mechanism that discharges the liquid contained in the container body from the tip of the nozzle, the mouth portion of the container body has a shape that can be joined to the bottle joint portion, and When the inner diameter of the mouth is a (mm), a ≧ 24 (mm) is satisfied, the horizontal distance from the central axis of the container body to the tip of the nozzle is b (mm), Bottle contact {C + 14 (mm)} ≦≦ when the horizontal distance from the central axis to the outer peripheral part of the container is c (mm) and the horizontal distance from the central axis to the outer peripheral part of the outermost container body is d (mm) When b ≦ d is satisfied and the horizontal distance from the central axis to the outer periphery of the head in the direction in which the nozzle is provided is e (mm), b ≧ e ≧ {c−5 (mm)} When the distance between the lower surface of the head and the upper surface of the bottle joint when the nozzle head is pushed down is defined as f (mm), 6 (mm) ≦ f ≦ 15 (mm) is satisfied. It is characterized by that.

In the liquid container of the present invention, when the horizontal distance from the central axis to the outer periphery of the head in the direction opposite to the direction in which the nozzle is provided is g (mm), 0 (mm ) ≦ c−g ≦ 6 (mm).
Further, the liquid product of the present invention is a liquid product used for hand washing, finger sterilization, disinfection, or sterilization, and is contained in the liquid container according to claim 1 or 2. It is characterized by.

  According to the present invention, it is easy to pour liquid in a refill pouch, excellent in workability of refilling work, and easy to push when discharging the content liquid, and excellent in usability to easily receive the discharged liquid by hand. Can provide a container.

Hereinafter, the present invention will be described in more detail.
FIG. 1 is a view showing an example of a liquid container according to the present invention. FIG. 1 (a) is a plan view, and FIGS. 1 (b) and 1 (c) are side views. FIG. 1B is a diagram showing a state when the nozzle head is pushed down, and FIG. 1C is a diagram showing a state when the nozzle head is not pushed down.
The container for liquid shown in FIG. 1 can be used as a container for storing any liquid such as shampoo, body soap, hand soap, dish detergent, garment detergent, lotion, emulsion, etc. It is suitably used as a container for a liquid product in which the liquid inside is taken out and used.

A liquid container 10 shown in FIG. 1 includes a container main body 1 that contains a liquid, and a liquid ejection device 2 that is used by being attached to the container main body 1.
The liquid container 10 can have an arbitrary height, but when the liquid container 10 has a size that can be used by hand, the height of the liquid container 10 is preferably in the range of 80 mm to 200 mm.

The container body 1 is provided with a mouth portion 12 having a shape that can be joined to the bottle joining portion 21 of the liquid ejection device 2. The mouth portion 12 of the container body 1 satisfies a ≧ 24 (mm) when the inner diameter is a (mm), and has a shape that can be joined to the bottle joining portion 21 of the liquid ejection device 2. If so, the larger the inner diameter a (mm), the better.
In the present embodiment, since the inner diameter a of the mouth portion 12 of the container body 1 exceeds 24 mm, the container body 1 is made of a rectangular bag or has a spout formed at the upper end corner of the rectangular bag. The benefits of refilling work from a refill pouch of any shape to the container body 1 can be obtained. In particular, when a refilling operation from a refilling pouch having a protruding spout having a general size to the container body 1 is performed, the spout of the refilling pouch can be inserted into the mouth portion 12 of the container body 1. This will greatly improve the ease of pouring the liquid in the refill pouch.

  However, when the inner diameter a of the mouth portion 12 of the container body 1 is less than 24 mm, it becomes difficult to insert the pouch spout having a protruding spout into the mouth portion 12 of the container body 1, and The ease of pouring the content liquid does not improve. For example, when the inner diameter a of the mouth portion 12 is less than 24 mm, it is conceivable to prepare a refill pouch having a small spout according to the inner diameter a of the mouth portion 12 of the container body 1. However, in general, in a refill pouch, it is difficult to narrow the width of the bonding portion. Therefore, in order to reduce the spout, the liquid passage portion in the spout is narrowed and the liquid is discharged. However, there is a problem that it takes a long time.

In addition, the width D1 of the container body 1 is preferably in the range of 35 mm to 100 mm in order to be easy to use when it is held in hand. Further, the planar shape of the container body 1 can be an elliptical shape as shown in FIG. 1A, but may be any shape, for example, a circular shape or an oval shape. When the planar shape of the container body 1 is an ellipse or an ellipse, the ratio of the width D1 and the thickness D2 of the container body 1 is in the range of 1.0 to 1.7, and the circumference of the container body 1 is By making the range of 113 mm to 280 mm, the liquid ejection device 2 is easy to grip and easy to use when held in hand.
The volume of the container body 1 can be arbitrarily selected, but when it is set to a size that can be used by hand, it is preferably set to a volume of 200 mL to 350 mL.

The liquid ejection device 2 includes a bottle joint portion 21, a nozzle head 22, and a pump mechanism 25.
The bottle joint portion 21 is detachably joined by being screwed to the mouth portion 12 of the container body 1.
The nozzle head 22 includes a head 24 provided with a nozzle 23, and is supported so as to be movable in the vertical direction while being biased upward as shown in FIG. 1 (c). .
As shown in FIG. 1B, the pump mechanism 25 pushes down the nozzle head 22 against the urging force urged upward, thereby pumping the liquid contained in the container body 1 and It is discharged from the tip.

  Further, as shown in FIG. 1, the liquid ejection device 2 has a horizontal distance from the central axis 11 of the container body 1 to the tip of the nozzle 23 b (mm), from the central axis 11 to the outer peripheral portion of the bottle joint 21. Where c (mm) is the horizontal distance and d (mm) is the horizontal distance from the central axis 11 to the outer periphery of the outermost container body 1, {c + 14 (mm)} ≦ b ≦ d is satisfied. Is. Therefore, the liquid container 10 shown in FIG. 1 is excellent in usability because the discharged liquid is not easily spilled from the hand, and is not easily damaged during distribution.

When the horizontal distance b from the central axis 11 to the tip of the nozzle 23 is shorter than the length 14 mm longer than the horizontal distance c from the central axis 11 to the outer periphery of the bottle joint 21, the nozzle 23 is pushed down to reduce the nozzle 23. When the liquid is discharged from the bottle, the bottle receiving portion 21 is obstructed by the hand that receives the discharged liquid, so that the discharged liquid is received at the end of the hand. Therefore, the discharged liquid is easily spilled from the hand, and the usability is reduced.
The maximum value of the inner diameter a of the mouth portion 12 provided in the container main body 1 described above is determined by the horizontal distance c from the central axis 11 to the outer peripheral portion of the bottle joint portion 21.
Further, when the horizontal distance b from the central axis 11 to the tip of the nozzle 23 is longer than the horizontal distance from the central axis 11 to the outer peripheral portion of the outermost container body 1, the tip of the nozzle 23 is not in circulation. It becomes easy to break.

Further, the liquid ejection device 2 has b ≧ e ≧ {c− when the horizontal distance from the central axis 11 of the container body 1 to the outer periphery of the head 24 in the direction in which the nozzle is provided is e (mm). 5 (mm)}. Therefore, the liquid container 10 shown in FIG. 1 is easy to push and has excellent usability.
When the horizontal distance e from the central axis 11 to the outer periphery of the head 24 in the direction in which the nozzle is provided exceeds the horizontal distance b from the central axis 11 to the tip of the nozzle 23, the nozzle 23 which is a liquid discharge port Since the tip of the head is covered with the head 24, it is difficult to confirm the position at which the liquid is discharged when the liquid is discharged, and it becomes difficult to receive the discharged liquid.

Further, the horizontal distance e from the central axis 11 to the outer periphery of the head 24 in the direction in which the nozzle is provided is shorter than the length obtained by subtracting 5 mm from the horizontal distance c from the central axis 11 to the outer peripheral part of the bottle joint 21. In this case, the head 24 is small and difficult to press, and the usability when discharging the liquid may be reduced.
In addition, when the above-described distance e is shorter than the length obtained by subtracting 5 mm from the above-described distance c, the tip of the head 24 is close to the outer peripheral portion of the bottle joint portion 21, and the bottle joint portion 21 becomes an obstacle to discharge liquid. There is a risk that the usability during the process may be reduced. Specifically, for example, as shown in FIG. 2, the head 24 is pushed with the thumb while keeping the palm facing upward, and the liquid discharged from the nozzle 23 is received in the same palm as the hand that pushed the head 24. When the liquid in the liquid container 10 is taken out by the method of use, the index finger may hit the bottle joint 21 and the thumb may not reach the head 24 in some cases. This problem is particularly noticeable in women and children with small hands.

Further, as shown in FIG. 1B, the liquid ejection device 2 according to the present embodiment sets the distance between the lower surface of the head 24 and the upper surface of the bottle bonding portion 21 when the head 24 is pressed down to f (mm). In this case, 6 (mm) ≦ f ≦ 15 (mm) is satisfied.
Conventionally, a container employing a large-bore bottle has a problem in that the hand receiving the liquid hits the bottle joint 21 because the outer diameter of the pump joint increases as the diameter increases.
On the other hand, in the liquid ejection device 2 according to the present embodiment, a space of 6 mm to 15 mm exists between the lower surface of the head 24 and the upper surface of the bottle bonding portion 21 when the head 24 is pushed down. The hand that receives the liquid can be disposed at a position closer to the central axis 11 than the horizontal position of the outer peripheral portion of the bottle joint portion 21 without being obstructed by 21. For this reason, the liquid discharged from the head 24 is discharged to the end of the palm of the hand and the liquid can be prevented from spilling from the hand, and the discharged liquid can be easily received by hand.

When the distance f between the lower surface of the head 24 and the upper surface of the bottle joint portion 21 when the head 24 is pushed down is less than 6 mm, the hand that receives the liquid is more than the horizontal position of the outer peripheral portion of the bottle joint portion 21. Since it becomes difficult to arrange | position in the position close | similar to the central axis 11, it is not preferable.
Further, when the distance f described above exceeds 15 mm, the liquid container 10 becomes unstable, so that the liquid container 10 is wobbled and the head 24 is difficult to be pushed down, and the usability may be reduced. Moreover, when the distance f mentioned above exceeds 15 mm, the risk of the nozzle head 22 being damaged when the head 24 is pushed down increases.
When the above-mentioned distance f exceeds 15 mm, for example, as shown in FIG. 3, the liquid container 10 is held in one hand, the head 24 is pushed with the index finger of the same hand, and the liquid is discharged from the nozzle 23. The person holding 10 may take the index finger hard to reach the head 24 when the liquid in the liquid container 10 is taken out by a method of receiving the liquid by the hand of another person. This problem is particularly noticeable in women and children with small hands.

  Further, in the liquid ejection device 2 of the present embodiment, when the horizontal distance from the central axis 11 of the container body 1 to the outer periphery of the head 24 in the direction opposite to the direction in which the nozzles 23 are provided is g (mm). In addition, 0 (mm) ≦ {c−g} ≦ 6 (mm) is satisfied. Therefore, the liquid container 10 shown in FIG. 1 is easy to push the head 24 and is easy to use. In particular, when the liquid in the liquid container 10 is taken out by the method of use shown in FIG. It is also easy to use for women and children with small hands.

The horizontal distance g from the central axis 11 of the container body 1 to the outer periphery of the head 24 in the direction opposite to the direction in which the nozzles 23 are provided is the horizontal distance c from the central axis 11 to the outer peripheral part of the bottle joint 21. 3 is preferable because, for example, when the liquid in the liquid container 10 is taken out by the method of use shown in FIG. 3 described above, the outer periphery of the head 24 hits the vicinity of the first joint of the index finger, and the head 24 is difficult to press and difficult to use. Absent.
Further, when the difference (c−g) between the distance g and the distance c is larger than 6 mm, for example, when the liquid in the liquid container 10 is taken out by the method of use shown in FIG. May not reach sufficiently and the head 24 may be difficult to press.

As a method for taking out the liquid in the liquid container shown in FIG. 1, for example, as shown in FIG. 2, the head 24 is pushed with the thumb while keeping the palm facing upward, and the same as the hand pushing the head 24. The usage method which receives the liquid discharged from the nozzle 23 to the palm is mentioned. The method shown in FIG. 2 is often performed when the liquid contained in the liquid container is a hand soap and it is necessary to quickly clean fingers during cooking.
Further, as shown in FIG. 3, as a method of taking out the liquid from the liquid container shown in FIG. 1, the container is held in one hand, the head 24 is pushed with the index finger of the same hand, the liquid is discharged from the nozzle 23, and the container is removed. The person who has it can use the method of receiving liquid by the hand of another person. The method shown in FIG. 3 is a method assumed when, for example, an adult pushes the head 24 and puts liquid on the palm of the child when the child is washing his / her hand.
Further, as a method of taking out the liquid in the liquid container shown in FIG. 1, as shown in FIG. 4, there is a usage method in which the head 24 is pushed with one hand and the liquid discharged from the nozzle 23 is received with the other palm. Can be mentioned.

  According to the liquid container 10 shown in FIG. 1, in any of the usage methods shown in FIGS. In particular, the liquid container 10 shown in FIG. 1 has good usability in the method of use shown in FIGS. 3 and 4, and when the fingers are dirty during use, or when the adult pushes the head 24 and the palm of the child Excellent usability can be obtained even when liquid is taken out. Accordingly, the liquid container 10 shown in FIG. 1 is very suitable as a liquid container for storing a liquid used for the purpose of hand washing, hand sterilization, disinfection, and sterilization.
