Description

  The present invention relates to a discharge container capable of discharging contents even when the container is inverted or horizontally, and particularly relates to a flexible tube of the discharge container.

  Conventionally, a spray container that ejects liquid in a container in a mist form is usually used in a posture in which the container is upright, and cannot be sprayed in an inverted posture. For example, a conventional spray container includes a pump device that sucks up liquid in the container, and a pipe attached to the pump device. This is because the pipe is made of, for example, low-density polyethylene and is hard, so that the mouth of the pipe comes out of the liquid in the inverted posture, and the liquid cannot be sucked up from the mouth. In this spray container, since the liquid can be sucked up through the pipe only when standing upright, the range of use of the spray container is limited.

Conventionally, there is known a spray container capable of ejecting liquid in a container in a mist state not only when standing upright but also when standing upside down.
Patent Document 1 discloses a right-and-left inverted spray container. This forward and reverse spray container is integrated with a stopper for restricting the movement of the valve body of each of the suction valve and the air blocking valve, and this stopper is configured to be slidable in the cylinder (FIG. 1 of Patent Document 1). ).
However, the upside-down dual-purpose spray container of Patent Document 1 is not easy to manufacture because the pump mechanism has a complicated configuration as compared to an upright dedicated spray container, and as a result, the price increases. Further, in the case of the upside-down dual-purpose spray container of Patent Document 1, when the container is turned sideways, there is a problem that the liquid cannot be ejected outside the container if the cylinder portion that sucks the liquid comes out of the liquid.

Therefore, conventionally, there has been devised a spray container that can be used both upside-down and without having a pump mechanism that supports both upside-down.
FIG. 8 is a view showing a conventional spray container 50. The spray container 50 includes a container main body 51 that stores the liquid W, a cap 52 that is detachably attached to a mouth portion (not shown) formed in the upper portion of the container main body 51, and the container main body 51 via the cap 52. A pump device 53 attached to the container body 51, a base tube portion 54 extending from the pump device 53 to the container main body 51, a tube 55 having one end attached to the base tube portion 54, and a weight attached to the other end of the tube 55 56. The tube 55 is made of a flexible material.
Here, the pump device 53 is equipped with a pump mechanism that sucks up the liquid W, and the liquid W in the container body 51 is guided into the pump mechanism through the tube 55 and the base tube portion 54 by the operation of the pump mechanism, After further compression, it is sprayed in the form of a mist through the nozzle 53A.
As shown by a solid line in FIG. 8, the spray container 50 is configured such that the tube 55 bends in a hairpin shape in an inverted posture and the liquid suction port at the distal end of the tube is always located in the liquid W.

  A spray container 50 shown in FIG. 8 is disclosed in FIG.

JP 2002-102754 A JP2000-28964A (FIG. 4B)

  However, in the conventional spray container 50 provided with the flexible tube 55, as shown by a broken line in FIG. 8, the tube 55 may stick to the container inner surface 51C in a posture in which the container is inverted. Even if the tube 55 is soft, the liquid suction port is not located in the liquid, so that it cannot be sprayed in an inverted posture.

  In order to solve this problem, it is possible to peel the tube 55 from the container inner surface 51C by increasing the weight 56 provided in the vicinity of the liquid suction port of the tube 55. However, the weight of the spray container 50 itself increases. . Moreover, when the weight 56 becomes heavy, the collision load with the inner surface 51C of the container also increases, which may cause abnormal noise.

  An object of this invention is to provide the flexible tube which can solve said problem, and can prevent sticking to the inner surface of a container, and a discharge container using the tube.

In order to achieve the above-described object, the present invention provides a discharge section including a storage section that stores liquid or powder contents, and a discharge section that is attached to the opening of the storage section and sucks up the contents and discharges the contents to the outside. The container includes a flexible tube having one end attached to the discharge portion and a weight attached to the other end, and is characterized in that the outer surface of the tube is formed to have a rough surface.
The contents contained in the discharge container of the present invention, that is, liquid or powder, are used for cosmetics such as perfumes and hairdressing agents, hygiene such as insect repellents, medical such as disinfectants such as alcohol and liquid drugs, and plant growth. It is not limited to agricultural uses such as chemicals and insecticides for use, and the place of use is not limited to household use, industrial use, and academic use. Further, the liquid includes a liquid material having a viscosity such as a gel or cream.

  In the discharge container of the present invention, preferably, the inner surface of the tube is formed to have a rough surface.

In order to achieve the above object, the present invention provides a discharge container comprising a storage portion for storing the contents of liquid or powder, and a discharge portion attached to the opening of the storage portion for sucking up the contents and discharging the contents to the outside. A flexible tube that has one end attached to the discharge portion and a weight attached to the other end, and is characterized in that the outer surface is formed in a rough surface.

And a weight 16.

  As shown in FIG. 2, the accommodating portion 11 has a bottom portion 11B on the disk, a cylindrical portion 11D coupled upward from the outer periphery of the bottom portion 11B, and a diameter decreasing as it goes upward from the upper portion of the cylindrical portion 11D. It comprises a tapered portion 11E and a mouth portion 11A formed on the upper portion of the tapered portion 11E. The accommodating portion 11 is composed of low density polyethylene (Low Density Polyethylene: LDPE), high density polyethylene (High Density Polyethylene: HDPE), polypropylene (Polypropylene: PP), polyethylene terephthalate (Polyethylene terephthalate: PET), polystyrene (polystyrene: PS). ), Polycarbonate (polycarbonate: PC), etc., a metal container, a glass container, and a ceramic container made of aluminum or stainless steel may be used.

  The cap 12 is formed in a cylindrical shape with a resin material, like the housing portion 11. Although not shown, the cap 12 is formed with a female screw on the inner surface, and the female screw and a male screw 11F (see FIG. 2) on the outer surface of the mouth portion 11A of the housing portion 11 are screwed together to form the cap 12. Is attached to the accommodating portion 11. When the cap 12 is attached to the accommodating portion 11, the pump device 13 is attached to the accommodating portion 11 by sandwiching, for example, a flange 13D (see FIG. 2) of the pump device 13 between them.

  The pump device 13 is equipped with a pump mechanism (not shown) that sucks up the liquid W. A part of the pump mechanism is configured by a base tube portion 14, and the base tube portion 14 projects downward from the bottom of the pump device 13.

  Further, the pump device 13 includes a nozzle 13A and a trigger 13B. The trigger 13B is formed in an arc shape, and one end thereof is rotatably supported by the case 13C of the pump device 13.

  When the user pulls the trigger 13B, the pump mechanism is operated, and the liquid W in the accommodating portion 11 is guided into the pump mechanism through the tube 15 and the base tube portion 14, and further compressed, and then is passed through the nozzle 13A. And gushes out to the outside. The pump mechanism is also configured to pump a predetermined amount of liquid in the container.

The tube 15 is configured to be flexible, that is, to be bent softly without bending.
FIG. 3 is a schematic cross-sectional view of the tube 15 according to the embodiment of the present invention, which is designed to have the dimensions shown in Table 1 below. 3 is a cross-sectional view taken along the line AA in FIG.

The tube in Table 1 is made of, for example, silicon. Specifically, it is configured as a rubber having silicon and oxygen in the main chain.

  Furthermore, the tube 15 of this embodiment has a plurality of concave portions 15A and convex portions 15B on the tube outer surface 150 as shown in FIG. By these irregularities, the tube outer surface 150 is formed into a rough surface, that is, a rough surface having irregularities. 4 is a cross-sectional view taken along the line AA in FIG. 2, as in FIG.

When the tube 15 is manufactured by an extrusion molding machine, the surface of the tube 15 can be formed into a rough surface by adjusting the extrusion speed of the tube to be manufactured.
Further, instead of such a roughening method for the tube outer surface 150, a glossy surface tube may be manufactured, and then the surface may be shaved with an abrasive or sandpaper to form a rough surface.

  As shown in FIG. 1, the dimensions of the tube 15 are selected so as to be longer than the distance L from the mounting position of the base tube portion 14 to the container bottom 11B.

  The weight 16 attached to the distal end portion of the tube 15 is made of, for example, metal or ceramic. The weight in the illustrated example is spherical, but the shape is not limited to the illustrated example. The weight 16 is made of a material having a specific gravity heavier than that of the contents of the accommodating portion 11.

  The spray container 10 configured as described above has the tube 15 easily bent in an inverted posture as shown in FIGS. 5A and 5B, and the suction port with the weight 16 is always in the liquid. enter. Further, as shown in FIG. 5C, the suction port always enters the liquid even when the container is laid down. Therefore, the liquid W can be sprayed out of the container in a mist state even in an inverted posture or a horizontal posture.

  In addition, even when the tube 15 comes into contact with the container inner surface 11C when moving from the upright posture to the inverted posture, the tube 15 is quickly separated from the container inner surface 11C because the tube surface is formed in a rough surface. Can do.

  Thus, in the spray container 10 of this embodiment, since the outer surface of the flexible tube 15 is formed as a rough surface, the tube 55 is pasted on the container inner surface 51C like the conventional spray container 50 shown in FIG. In addition, it is possible to avoid falling into an unusable state.

FIG. 6 is a schematic view of a spray container 20 according to another embodiment of the present invention.
The spray container 20 is different from the spray container 10 of FIG. 1 in that the pump device 23 is not a spray gun type but a push button type. The pump device 23 in FIG. 6 includes a pump mechanism (not shown) that pumps a predetermined amount of the liquid in the container 11 inside the case 23C, and a nozzle 23A that makes the liquid W sucked up by the pump mechanism mist. Then, although it is the structure similar to the pump apparatus 13 of the spray container 10 of FIG. 1, it differs in the point which a pump mechanism operate | moves by pushing the button 23B.

The present invention can be implemented in various forms without departing from the spirit of the invention.
For example, the structure of the pump device is not limited to the above-described embodiment.
The discharge container of the present invention may be configured using a valve device instead of the pump device described above in the discharge unit. For example, as shown in FIG. 7, the discharge container of the present invention is configured as an aerosol 30 in which the accommodating portion 11 is constituted by a can and the can is filled with liquid / powdered contents and liquefied gas. You can also In this case, when the button 31 is pressed, the valve of the valve device 32 is opened, that is, the inside of the housing portion is electrically connected to the outside of the container, and the contents (not shown) are discharged out of the container by the liquefied gas pressure.
Further, the shape and size of the container and the cap are not limited to the illustrated examples.
Further, the tube may be made of not only a silicon material but also other resin materials, that is, the tube may be configured to have flexibility.

In the tube of the present invention, not only the tube outer surface 150 but also the inner surface 160 may be formed in an uneven rough surface as shown in FIG. In this case, even if the inner surfaces of the tubes are likely to stick to each other due to the negative pressure in the tube, the inner surfaces are uneven, and therefore the tube can be prevented from being blocked.
Similar to the roughening method of the tube outer surface, the tube inner surface 160 can be formed into a rough surface by adjusting the extrusion speed of the tube with an extruder. Further, the shape of the nozzle of the molding machine may be devised, and ribs may be provided on the inner surface 160 to form an uneven rough surface.

  The discharge container and the tube of the present invention are not limited to the so-called “spray” in which the contents in the container are ejected in a mist, and the contents in the container may be directly discharged out of the container. In addition, by providing a propeller, a mesh member, or the like instead of a nozzle at the mouth of a discharge unit such as a pump device or a valve device, the contents, for example, liquid can be spouted out in a foam state, or a plurality of ports can be placed at the mouth of the discharge unit The discharge container of the present invention can be configured such that a hole can be provided to discharge liquid in a shower shape, or a single hole can be provided in the mouth of the discharge section to discharge liquid in a string shape.
