JP5492715B2 - Discharge container for liquid and liquid cleaning agent in container - Google Patents

Description

  The present invention relates to a liquid discharge container and a container-containing liquid cleaning agent.

 In general, liquid cleaners for home use may be applied directly to the object to be cleaned, so they are filled in containers according to their use, such as toilets, glass, bathrooms, drain pipes, furniture, etc. And are commercially available. For example, spray-type containers are used for applications where a liquid detergent is applied over a wide range, such as for glass and furniture. On the other hand, for applications such as toilets, drain pipes, bathrooms, etc., where a liquid cleaning agent is applied in a narrow range, a squeeze type that discharges the cleaning agent in a straight line from the discharge hole by pressing the container body with a hand. These containers are used. This squeeze-type container is generally known to include a container main body that stores a liquid cleaning agent, and a nozzle that is provided at the mouth of the container main body and has a discharge hole.

Usually, the discharge hole is formed at the top of the nozzle and is formed to discharge the content liquid in a direction substantially perpendicular to the bottom surface of the container. For this reason, depending on the shape of the target (application target) to which the content liquid is applied, it is difficult to accurately apply the content liquid to the application target.
For example, the edge of the toilet bowl and the drainage port of the kitchen are places where it is difficult to apply the liquid cleaning agent due to its structure. For example, when applying the liquid cleaning agent to the rim of the toilet, it is necessary to make the discharge hole face upward and insert the container deeply into the toilet, and the operation of directing the discharge hole to the application target is complicated.

 Conventionally, with respect to such problems, a neck for facilitating the application of the liquid cleaning agent to the surface to be cleaned is provided. The length of the neck from the liquid cleaning agent discharge port to the upper end of the trunk is 50 mm or more. There has been proposed a squeeze container having a maximum diameter of 50 mm or less and a restoring speed of the body thickness after discharging the content liquid set to 1500 mm / sec or more (for example, Patent Document 1). According to this squeeze container, the discharge hole is formed so that the content liquid is discharged to the side, and the body portion is quickly recovered, so that the liquid cleaning agent can be applied to a narrow portion.

JP 2005-96839 A

However, as in the technique of Patent Document 1, simply by directing the discharge hole to the side, the improvement in the control of the discharge direction is insufficient, and it is difficult to apply the liquid cleaning agent to the rim of the toilet, etc. was there.
Therefore, an object of the present invention is to provide a liquid discharge container that can easily apply the content liquid to a place such as the back of the toilet bowl.

 As a result of intensive studies, the inventors of the present invention can easily and accurately apply to the edge of the toilet bowl by tilting the communication direction between the container body and the discharge nozzle with respect to the attitude of the container body when the container body is gripped. The present inventors have found that the contents can be applied and have completed the present invention.

That is, the liquid discharge container of the present invention includes a container main body that contains the content liquid and has a cylindrical mouth portion at the top, and a discharge nozzle that is attached to the mouth portion and has a discharge hole that discharges the content liquid. A bulging surface that is pressed by a finger when discharging the content liquid is formed on the bottom surface side of the container body, and the liquid discharge container in which the discharge direction of the discharge hole intersects the axis of the mouth In the bulging surface, a ridge line portion having a top portion extending in one direction is formed by intersecting the ridge line portion or an extension line thereof with the axis, and the ridge line portion is at least on the basis of the axis. A part of the region from the intersecting portion to the bottom surface side is located on the same side as the discharge direction of the discharge holes.
The axis is preferably substantially orthogonal to the bottom surface of the container body or an extension line thereof, the bulging surface is substantially circular, and the container body is a side surface that bulges along the peripheral edge of the bulging surface. Is more preferably formed.

  The liquid detergent contained in the container of the present invention is characterized in that the liquid detergent is accommodated in the liquid discharge container of the present invention.

According to the liquid discharge container of the present invention, on the bulging surface, a ridge line portion whose top portion extends in one direction is formed by intersecting the ridge line portion or an extension line thereof with the axis of the mouth of the container body, Since the ridge line portion is located on the same side as the discharge direction of the discharge hole, at least a part of the region from the intersecting portion to the bottom surface side of the container main body is located on the same side as the discharge direction of the toilet hole. The content liquid can be easily and accurately applied to any place.
According to the liquid discharge container of the present invention, since the axis is substantially orthogonal to the bottom surface of the container body or its extension line, filling of the content liquid is easy and productivity is not impaired.
According to the liquid discharge container of the present invention, the bulging surface is substantially circular, and the container body is formed with a side surface that bulges along the periphery of the bulging surface. The body can be gripped.

(First embodiment)
The liquid discharge container according to the first embodiment of the present invention will be described below with reference to FIGS.
As shown in FIG. 1, the liquid discharge container 1 includes a lid body 2, a nozzle cap 3, and a container body 4, and stores the content liquid in the container body 4.

 The container body 4 includes a body portion 42 erected from the periphery of the bottom surface 44, and a substantially cylindrical mouth portion 40 above the body portion 42. On the bottom surface 44 side of the container body 4, an elliptical bulging surface 50 is formed on the front surface and the back surface (not shown), and a ridge line portion 52 is formed on the bulging surface 50. As shown in FIG. 2, the bulging surface 50 has a shape that bulges to the front and the back, and the ridge line portion 52 is a top portion 52 a, 52 b, 52 c, 52 d that is the most bulged point in a cross section parallel to the bottom surface 44. , 52e extend in one direction. The container body 4 has a shape in which the left side surface 46 and the right side surface 48 bulge along the peripheral edge of the bulging surface 50.

The nozzle cap 3 is attached to the mouth portion 40, and includes a lower tube portion 16 that fits into the mouth portion 40, an upper tube portion 14 that is erected on the upper portion of the lower tube portion 16, and an upper tube portion 14. The discharge nozzle 10 provided in the upper part of this is provided. Inside the lower cylinder part 16 and the upper cylinder part 14, a flow path for allowing the content liquid in the container body 4 to flow to the discharge nozzle 10 is formed, and the content liquid is discharged to the discharge nozzle 10 in the discharge direction F. A discharge hole 12 is formed.
The lid 2 is fitted with the upper cylinder portion 14 of the nozzle cap 3 and covers the discharge nozzle 10.

The ridge line portion 52 intersects the communication direction of the discharge nozzle 10 and the container body 4, that is, the axis O1 of the mouth 40, and the intersection of the ridge line portion 52 and the axis O1 is defined as the ridge line vertex P1, and the mouth 40 from the ridge line vertex P1. An inferior angle formed by the axis O1 toward the ridge line 52 and the ridge line portion 52 from the ridge line vertex P1 toward the bottom surface 44 is defined as an intersection angle θ1. Here, the minor angle is the smaller one of the angles sharing the two sides with the vertex. In the present embodiment, the minor angle at the ridge line vertex P1 is formed on the left side 46 side. Thus, in the ridge line portion 52, the region from the ridge line vertex P1 to the bottom surface 44 is positioned on the left side surface 46 side with respect to the axis O1.
Crossing angle (theta) 1 is an obtuse angle, for example, 120 degrees or more and less than 180 degrees are preferable, 135-170 degrees are more preferable, 150-165 degrees are further more preferable. By setting such an intersection angle, the content liquid can be easily and accurately applied to the edge of the toilet seat and the like.
In the present embodiment, the axis O <b> 1 is substantially orthogonal to the bottom surface 44. By forming the opening 40 so as to be substantially orthogonal to the bottom surface 44, the container body 4 can be easily filled with the content liquid and the nozzle cap 3 can be easily mounted even in the conventional production line for liquid products in a container. It is. Note that “substantially orthogonal” means that the angle formed between the axis O1 and the bottom surface 44 is 85 to 95 °.

The discharge hole 12 has an intersection between the discharge direction F and the axis O1 as a discharge direction vertex P2, a region in the discharge direction F from the discharge direction vertex P2 toward the discharge hole 12, and an axis line from the discharge direction vertex P2 toward the mouth 40. It is formed in the discharge nozzle 10 so that the inferior angle made with O1 becomes the crossing angle θ2. The intersection angle θ2 is formed on the left side 46 side, that is, in the same direction as the intersection angle θ1. Thus, the discharge direction F is on the left side 46 side, that is, the inferior angle side of the ridge line vertex P1, and the region from the ridge line vertex P1 to the bottom surface 44 of the ridge line portion 52 is the discharge direction of the discharge holes 12 with respect to the axis O1. It is supposed to be located on the F side.
The crossing angle θ2 is preferably 90 to 180 °, more preferably 100 to 170 °, and still more preferably 110 to 130 °. When the intersection angle θ2 is less than 90 °, the content liquid may be applied to the handle or the container body when the content liquid is discharged.
Further, the discharge direction F is directed upward in the vertical direction with respect to the horizontal or horizontal direction when the liquid discharge container 1 is placed (standing state) with the bottom surface 44 being horizontal. By making the discharge direction F in this way, it is possible to prevent liquid from dripping from the discharge holes 12 when the liquid discharge container 1 is in an upright state.
The hole diameter of the discharge hole 12 can be determined according to the type and use of the content liquid, and is, for example, φ0.5 to 8 mm.

 The container body 4 is formed by molding a material conventionally used for a container for storing a liquid, such as polyethylene, polyethylene terephthalate, polypropylene, vinyl chloride, silicon elastomer, and urethane.

The magnitude | size of the container main body 4 can be determined according to a use and the filling amount of a content liquid, for example, when using a liquid detergent as a content liquid, it is set to 400-1000 mL.
The height of the container body 4 can be determined in consideration of the internal volume, the size of the nozzle cap 3, and the like. For example, when the nozzle cap 3 is mounted, the distance between the bottom surface 44 and the tip 11 of the nozzle cap 3 is 200 to 200. The height is 300 mm.
Further, the width of the container body 4 can be determined in consideration of the internal volume, the height of the container body 4 and the like. For example, the maximum value of the distance between the left side surface 46 and the right side surface 48 is 70 to 130 mm.

 When the bulging surface 50 is pressed with a finger, the thickness of the bulging surface 50 is flexible so that the bulging surface 50 on the front side and the bulging surface 50 on the back side approach each other, and when pressing with the finger is released, The bulging surface 50 only needs to be restored to the shape before pressing, and can be determined in consideration of the material of the container body 4.

The degree of bulging of the bulging surface 50 is not particularly limited, but the contour of the bulging surface 50 in a cross section parallel to the bottom surface 44 is preferably, for example, a radius of curvature R = 50 to 100 mm, and 70 to 90 mm. Is more preferable. If it is the said range, the container main body 4 can be stably hold | gripped by the usage method mentioned later.
The degree of bulging of the left side surface 46 is not particularly limited, but the contour of the left side surface 46 in front view is preferably, for example, a curvature radius R = 80 to 150 mm, and more preferably 100 to 130 mm. If it is the said range, the container main body 4 can be stably hold | gripped by the usage method mentioned later.
The degree of bulging of the right side surface 48 is not particularly limited, but the contour of the right side surface 48 in front view is preferably, for example, a radius of curvature R = 150 to 300 mm, and more preferably 250 to 280 mm. If it is the said range, the container main body 4 can be stably hold | gripped by the usage method mentioned later.

Examples of the material of the nozzle cap 3 include resins such as polyethylene, polyethylene terephthalate, polypropylene, vinyl chloride, silicon elastomer, and urethane.
The material of the lid 2 is the same as the material of the nozzle cap 3.

Examples of the content liquid include liquid cleaning agents and machine oils used for cleaning toilets, bathrooms, drain pipes, and the like.
The physical properties of the content liquid can be determined according to the application. For example, when the content liquid is used as a toilet cleaning agent, the liquid stays attached to the application target and is easily removed from the discharge hole 12 when the bulging surface 50 is pressed with fingers. The content liquid can be discharged. For example, the content liquid has a viscosity at a shear rate decrease of 0.5 sec ⁻¹ measured with a Haake RS-100 viscometer at 25 ° C., preferably 80 mPa · s or more, more preferably 100 to 2000 mPa · s. is there. If the viscosity at a reduction in the shear rate of 0.5 sec ⁻¹ is less than 80 mPa · s, the residence in the coating object becomes insufficient.
The content liquid has a viscosity at a shear rate of 1000 sec ⁻¹ or more, preferably 20 mP · s or less, more preferably 5 to 15 mPa · s. When the viscosity at a shear rate of 1000 sec ⁻¹ or more is more than 20 mPa · s, when releasing the pressure on the bulging surface 50, the content liquid remains in the mouth 40 and obstructs the airway, Restoration of the bulging surface 50 is delayed.

The composition of the content liquid can be determined according to its use, and includes one containing various cleaning components. For example, cleaning components for toilet cleaners include glycolic acid, diglycolic acid, gluconic acid, oxalic acid, malic acid, citric acid, lactic acid, tartaric acid, acetic acid, hydroxyethanediphosphonic acid, malonic acid, hydrochloric acid, sulfuric acid, Acid components such as nitric acid, phosphoric acid, tripolyphosphoric acid, sulfamic acid, chlorine bleach components such as sodium hypochlorite, oxygen bleach components such as hydrogen peroxide, alkali agent components such as sodium hydroxide and potassium hydroxide And chelating agent components such as aminocarboxylic acid, polycarboxylate, and polyphosphate, and abrasives such as calcium carbonate, silica, and alumina. These can be used in combination.
In addition, the content liquid contains a surfactant such as an anionic surfactant, a cationic surfactant, a nonionic surfactant, and an amphoteric surfactant for the purpose of washing components and foaming. Also good.

 For the purpose of adjusting the viscosity, the content liquid is, for example, a natural polysaccharide polymer represented by xanthan gum, guar gum, etc., hydroxyethyl cellulose, carboxymethyl cellulose, cationized cellulose, polyacrylate and acrylic acid copolymer, polystyrene. Thickeners such as inorganic viscosity minerals such as styrene acid copolymers such as acid salts, synthetic polymers such as polyvinyl alcohol, polyvinyl pyrrolidone, and chitosan may be contained.

Next, a first method of using the liquid discharge container 1 will be described with reference to FIGS. FIG. 3 is a perspective view for explaining a state in which the container body 4 is gripped from the right side surface 48 and the content liquid is applied to the back of the toilet bowl.
The container body 4 is filled with the content liquid, the lower cylinder portion 16 of the nozzle cap 3 is fitted into the mouth portion 40, and then the lid body 2 is fitted into the upper cylinder portion 14. Thus, liquid products in a container such as a liquid detergent in a container filled with a liquid detergent and a machine oil in a container filled with machine oil can be produced.

 When applying the content liquid of the liquid product in the container to the application target, the lid 2 is removed, the palm is placed on the right side surface 48, and the finger is brought into contact with the bulging surface 50 to hold the container body 4. At this time, since fingers are hung on the ridge line portion 52 of the bulging surface 50, the container body 4 is attracted to the palm of the hand and is gripped in a state where the direction of the ridge line portion 52 is fixed. The axis O1 is inclined in a direction away from the palm as it goes from the bottom surface 44 to the mouth portion 40.

 Next, as shown in FIG. 3, the palm is turned upward and the container body 4 is gripped so as to be placed on the palm, and the discharge nozzle 10 is operated so as to sink into the edge back 92 of the toilet 90. By this operation, the nozzle hole 12 is in a state facing the edge back 92. At this time, since the axis O1 is inclined in a direction away from the palm as it goes from the bottom surface 44 to the mouth portion 40, the nozzle hole is inserted without deeply inserting the handle into the toilet bowl 90 or bending the wrist greatly. 12 can easily be directed to the back of the rim. When the bulging surface 50 is pressed with a finger that holds the container body 4, the content liquid is discharged from the discharge hole 12 toward the edge back 92, and the discharged content liquid is applied to the edge back 92.

 A second method of using the liquid discharge container 1 will be described with reference to FIGS. FIG. 4 is a perspective view illustrating a state in which the container body 4 is gripped from the left side surface 46 and the content liquid is applied to the back of the toilet bowl.

 In applying the liquid content of the liquid product in the container to the application target, the lid 2 is removed, the palm is placed on the left side surface 46, and the finger is brought into contact with the bulging surface 50 to hold the container body 4. At this time, since the finger is put on the ridge line portion 52 of the bulging surface 50, the container body 4 is attracted to the palm of the hand, and the direction of the ridge line portion 52 is determined. The axis O1 is inclined in a direction approaching the palm as it goes from the bottom surface 44 to the mouth 40.

 Next, as shown in FIG. 4, the palm is turned downward, the container body 4 is gripped up, and the discharge nozzle 10 is operated so as to sink into the edge back 92 of the toilet bowl 90. By this operation, the nozzle hole 12 is in a state facing the edge back 92. At this time, since the axis O1 is inclined in the direction approaching the palm as it goes from the bottom surface 44 to the mouth portion 40, the nozzle hole is not inserted without deeply inserting the handle into the toilet bowl 90 or greatly warping the wrist. 12 can easily be directed to the back of the rim. When the bulging surface 50 is pressed with a finger that holds the container body 4, the content liquid is discharged from the discharge hole 12 toward the edge back 92, and the discharged content liquid is applied to the edge back.

  As described above, since the ridge line portion is formed on the bulging surface of the liquid discharge container according to the present embodiment, when gripping the container main body, fingers are hung on the ridge line portion, attracted to the palm, and stably. Grasped. In addition, the ridge line part intersects the axis of the mouth part, and at least a part of the region from the intersecting part to the bottom surface side is located on the same side as the ejection direction of the ejection holes with respect to the mouth axis. Therefore, the content liquid can be applied by directing the discharge hole to the back of the toilet bowl or the like without inserting the handle deep into the toilet bowl, or bending or bending the wrist of the handle greatly.
