By making the radial lengths of the first ring formation pieces 12 shorter than those of the corresponding second ring formation pieces 13, the first ring formation pieces 12 are orderly folded into the corresponding second ring formation pieces 13 when the nozzle main body 3 is pressed in the direction in which it is shortened.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a liquid fuel, drinking water,
The present invention relates to a liquid container nozzle mounted on a container for holding a liquid such as water.

[0002]

2. Description of the Related Art There are various types of containers for liquid fuel such as kerosene or the like, drinking water, water, etc., made of polyethylene or the like, and their capacities are 5, 9, 10, 18 liters and the like. These containers are convenient because liquids such as kerosene, drinking water, water, and the like can be carried to an arbitrary place because the containers can store and carry the liquid. When the liquid in the container is transferred to another machine, a container, or the like, a liquid container nozzle is attached to the opening of the container. The liquid container nozzle is formed, for example, in a cylindrical shape having a length of about 30 cm in the longitudinal direction (axial direction), and one end is attached to the opening of the container. For example, when kerosene in a container is put into a tank of a heating device, one opening of the container (usually a container is provided with two openings, so a nozzle is attached to one opening and the other is used for venting air) (Open), the other end of the nozzle is inserted into the opening of the tank and the container is lifted, so that the kerosene in the container flows into the tank without spilling through the nozzle.

[0003]

The above-described liquid container nozzle has a bellows-shaped peripheral surface, and the nozzle bends appropriately when the liquid is put into another container or the like. However, when the length of the nozzle in the longitudinal direction is long, the length of the nozzle becomes an obstacle and handling may be deteriorated. In addition, when not in use, the long nozzle becomes an obstacle when it is attached to the container, and becomes an obstacle. Further, when removed from the container, the convenience is poor, such as taking up space for storage.
The present invention has been made in view of such circumstances, and an object of the present invention is to provide a liquid container nozzle having excellent operability and functionality.

[0004]

In order to achieve the above object, a liquid container nozzle according to the present invention is a liquid container nozzle having a nozzle body having one end attached to an opening of a container for holding a liquid. The peripheral surface of the nozzle main body is formed in a bellows shape that can be extended and contracted and is bendable, and that maintains a stretched and bent state.

When the bellows shape extends the nozzle main body, the first ring forming side whose diameter gradually increases along the axial direction;
A first ring forming side at one end side of two adjacent forming sides forming a zigzag mountain formed by alternately arranging a large number of gradually reduced second ring forming sides. When the length of the nozzle in the radial direction is shorter than the length of the other second ring forming side, and when both ends of the nozzle body are pressed toward the other end, respectively, the first side is formed inside the second ring forming side. When the ring forming side is folded and the nozzle body is bent, the first ring forming side is folded inside the second ring forming side inside the bent portion and the first and second ring forming sides are folded outside the second ring forming side. It is preferable that the bellows structure is formed such that a zigzag mountain is formed by the sides and held in a bent state. Further, it is preferable that a plug for closing the outlet is detachably attached to the other end of the nozzle body. Further, it is preferable that a nozzle stopper for locking the nozzle body to the container is provided at one end of the nozzle body. Furthermore, it is preferable to provide a dripping prevention part for preventing dripping at the other end of the nozzle body.

[0006]

The peripheral surface of the nozzle body is formed in a bellows shape that can be extended and contracted and is bendable and that can maintain the extended and contracted state. Since it can be bent in any direction, handleability is improved. Also, even when the nozzle is attached to the liquid container, the nozzle is less likely to become a hindrance by shrinking the nozzle when not in use, and when it is removed from the container, if it is shrunk, the storage space is small. ,
Convenience also improves.

[0007]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. In FIG. 1, reference numeral 1 denotes a liquid container nozzle, and the nozzle 1 is mounted on the liquid container. As shown in FIG. 8, the liquid container is used to hold a liquid fuel such as kerosene and a liquid such as drinking water and water, and has various capacities such as 5, 9, 10, and 18 liters. There are a polyethylene container for storing kerosene, a polyethylene container that can be carried around a camp or a mountain, and that can contain drinking water, water, and the like. The liquid container 2 is provided with at least one or more openings through which liquid flows in and out, and the liquid container nozzle 1 is attached to the openings.

As shown in FIG. 1, the liquid container nozzle 1 includes a nozzle body 3, a nozzle stopper, and a tip cap 5. If the nozzle body 3 is cylindrical, the cross section is circular,
Any shape such as a polygon and a rectangle may be used. In particular, a cylindrical shape is preferable from the viewpoint of ease of manufacturing. In this embodiment, the cylindrical shape will be described. That is, the nozzle body 3 is formed in a cylindrical shape, and preferably, from one end portion (mounting portion mounted to the opening of the container 2) 6 to the other end portion (outflow portion through which the liquid flows out).
7 is formed into a cylindrical shape whose diameter is gradually reduced. As described above, the operability when the liquid flows out is improved by reducing the diameter of the outflow portion 7 side.

The one end (mounting portion) 6 of the nozzle body 3 may be formed by fitting, screwing, fastening, or the like as long as it is mounted on the opening of the container 2. For example, liquid fuel such as kerosene,
A cap for closing the opening is screwed into the opening of the commercially available container 2 for drinking water and water, and a nozzle stopper cap 4 which is a nozzle stopper screwed into this opening is used. It may be attached. . As shown in FIG. 5, the nozzle stopper cap 4 is a ring-shaped perforated cap, and is formed in a cylindrical shape in which a screwing groove 8 screwed into an opening of the container 2 is provided. , A ring-shaped flange 9 extending as appropriate along the radially inward direction is provided. The mounting part 6 is, as shown in FIGS.
The diameter is slightly smaller than the diameter of the opening of the container 2 and the inner diameter of the flange 9 of the nozzle stopper cap 4 (the diameter that can be inserted into the opening of the container 2). A contact flange 10 extending appropriately along the radially outer side is provided. The contact flange 10 contacts the end of the opening of the container 2 and has a diameter between the inner diameter of the nozzle stopper cap 4 and the diameter of the flange 9 of the cap 4. The nozzle stopper cap 4 is mounted on the nozzle body 3 by putting the mounting part 6 of the nozzle body 3 into the flange 9 of the nozzle stopper cap 4 in a state where the nozzle body 3 is softened with hot water or the like. When the flange 9 of the cap 4 comes into contact with the contact flange 10, the contact flange 10 is pushed into the flange 9 of the cap 4, and the flange 9 of the cap 4 is positioned on the other end 7 from the contact flange 10. That is, the nozzle stopper cap 4 is supported by the one mounting portion 6 of the nozzle body 3 so as to be rotatable in the circumferential direction, and the movement in the axial direction is restricted by the contact flange 10. Thereby, by screwing the nozzle stopper cap 4 into the opening of the container 2, the contact flange 10 contacts the end of the opening and acts as a packing, so that the nozzle body 3 is
, So that leakage of the liquid is prevented.

A central portion (peripheral surface) between the mounting portion 6 and the outflow portion 7 of the nozzle body 3 is formed in a bellows-like shape 11 which can be extended and contracted and bendable, and which can maintain the contracted and bent state. ing. The bellows shape 11 may be formed in any shape such as a circular, polygonal, or rectangular cross section as long as the bellows shape 11 can be expanded and contracted and bends and has a structure that maintains the expanded and contracted and bent state. A circular one is preferable, and the present embodiment describes a case of a circular cross section.

More specifically, the bellows shape 11 is such that when the nozzle body 3 is extended by pulling both end portions 6 and 7 of the nozzle body 3 in directions opposite to the other end portions 7 and 6, respectively, the nozzle body 3 is expanded as shown in FIG. As shown in the drawing, a first ring forming side 12 whose diameter is gradually increased from one end 6 to the other end 7 and a second ring forming side 13 whose diameter is gradually reduced are alternately arranged in a zigzag shape. Is what it is. In the bellows shape 11, a portion of a valley 14 forming a zigzag is located on the outer peripheral surface of the nozzle body 3 (located on a cylindrical peripheral surface whose diameter is gradually reduced from one end to the other end). In addition, the radial length of the first ring forming side 12 is formed shorter than the length of the second ring forming side 13, whereby both ends 6, 7 of the nozzle body 3 are respectively connected to the other end sides 7, 7. By pressing in six directions,
As shown in FIG. 3, the first ring forming side 12 is regularly folded inside the second ring forming side 13 so that the axial length of the nozzle body 3 is reduced.
Further, when the nozzle body 3 is bent, as shown in FIG.
With the first ring forming side 12 folded inside the
In the outer portion, the first and second ring forming sides 12, 13 are formed.
As a result, zigzag peaks 15 are formed.
The ring forming sides 12 and 13 are extended) and are held in a bent state.

The material and thickness of the bellows shape 11, that is, the material and thickness of the nozzle body 3 are arbitrarily determined as long as the material can expand and contract and bend, and can maintain the expanded and contracted and bent state. PE), polypropylene (PP), vinyl chloride resin (PVC), polyethylene terephthalate (PET), nitrile resin, etc., especially polyethylene (PE), polypropylene (P
P) is optimal because it can have a certain degree of hardness and has flexibility.

As shown in FIGS. 2 and 3, a dripping preventing portion 17 for preventing dripping is provided on the inner wall near the outlet 16 at the other end (outflow portion) 7 of the nozzle body 3. The liquid dripping prevention portion 17 is provided in an annular shape along the circumferential direction, and is formed to protrude in an arc shape inward in the radial direction. The tip cap 5 is attached to the outflow portion 7 of the nozzle body 3. The attachment of the tip cap 5 to the outflow portion 7 may be performed by any means such as fitting, screwing, and fastening, as long as the outlet 16 can be hermetically sealed. Here, the case of screwing will be described. Specifically, a ring-shaped ring groove 18 is provided along the circumferential direction on the outer periphery near the bellows portion 11 of the outflow portion 7 of the nozzle body 3, and a thread 19 is formed on the center outer periphery on the tip side. Is provided. As shown in FIGS. 1, 4, 6, and 7, the tip cap 5 is formed in a cylindrical shape with one end face closed, and a thread groove 22 screwed with the thread 19 is formed on the inner wall of the peripheral surface. Is provided, so that the outlet 16 of the nozzle body 3 is sealed.
In addition, a cylindrical sealing piece 23 extending along the axial direction is provided on the internal closing surface of the tip cap 5, and the sealing piece 23 is slightly larger than the inside diameter of the tip of the outflow portion 7 of the nozzle body 3. When the cap 5 is attached to the outflow portion 7, the sealing piece 23 is formed in the outflow portion 7 as shown in FIG.
Is inserted, and the sealing piece 23 comes into close contact with the inner wall in the vicinity of the outlet 16 so that the liquid does not easily flow out of the gap. Further, FIG. 1, FIG.
As shown in FIG. 4, FIG. 6, and FIG. 7, a connecting portion 21 to which an engaging ring 20 that engages with the ring groove 18 is attached is connected.

The tip cap 5 is manufactured by, for example, an injection molding method using a mold for a tip cap and using a main material such as polyethylene. The nozzle stopper cap 4 is manufactured by an injection molding method using a main material such as polyethylene using a nozzle stopper cap mold, for example. Further, the nozzle body 3 is manufactured by a blow molding method using a main material such as polyethylene or polypropylene using a nozzle body mold. The mold for the nozzle body, the mold for the tip cap, and the mold for the nozzle stopper cap should be prepared in advance so that the nozzle body 3, the tip cap 5, and the nozzle stopper cap 4 are manufactured as described above. Of course.

A tip cap 5 and a nozzle stopper cap 4 are attached to the manufactured nozzle body 3. Tip cap 5
The engagement ring 20 connected to the cap 5 via the connecting portion 21 is engaged with the ring groove 18, and the screw groove 22 of the tip cap 5 and the screw thread 19 of the nozzle body 3 are attached.
Are screwed together to seal the outlet 16 at the tip of the nozzle body 3. The nozzle stopper cap 4 is provided with the mounting portion 6 of the nozzle body 3 in the hole (hole of the flange 9) of the cap 4 as described above.
Is pressed in until the flange 10 passes through the hole. As a result, the tip cap 5 and the nozzle stopper cap 4 are attached to the nozzle body 3, and the nozzle stopper cap 4 of the nozzle body 3 is screwed into the opening of the liquid container 2 as shown in FIG. The nozzle body 3 can be mounted on the liquid container 2. Since the nozzle body 3 is attached to the opening of the container 2 using the nozzle stopper cap 4 in this manner, the nozzle body 3 and the container 2
The liquid does not flow out from between the openings. That is, when the nozzle stopper cap 4 is rotated in a predetermined direction in accordance with the opening of the container 2, the cap 4 and the opening are screwed together, and the contact flange 10 first contacts the end of the opening, and Is rotated, the joint flange 10 is pressed against the end of the opening to act as a packing, so that the nozzle body 3 comes into close contact with the opening of the container 2 and liquid does not leak.

When the liquid contained in the liquid container 2 is transferred to another container or the like, the tip cap 5 is removed, and the container 2 is appropriately tilted so that the liquid in the container 2 is discharged through the nozzle 1. It flows out of the outlet 16. On this occasion,
As shown in FIG. 1 to FIG. 4 and FIG. 8, the peripheral surface of the nozzle body 3 is formed in a bellows shape 11 which can expand and contract and bend, and maintains the expanded and contracted and bent state. The length can be adjusted to any length, and the nozzle 1 can be bent in any direction and maintain its length and direction. Thereby, the outlet 16 at the tip of the nozzle 1 can be held at an arbitrary position, so that the handleability of the nozzle 1 is improved, and the operability and functionality of the nozzle 1 are dramatically improved. Become. In addition, when the nozzle 1 is attached to the liquid container 2 or when the nozzle 1 is not used, the nozzle 1 is contracted and folded short, so that the nozzle 1 is hardly obstructed even when the nozzle 1 is attached to the opening of the container 2. At this time, the bellows shape 11 alternately arranges the first ring forming sides 12 and the second ring forming sides 13, and the alternately arranged first ring forming sides 12 are formed shorter than the second ring forming sides 13. Accordingly, when the both ends 6 and 7 of the nozzle body 3 are pressed toward the other ends 7 and 6 respectively, the first ring forming side 12 is regularly folded inside the second ring forming side 13. In addition, the length of the nozzle body 3 (nozzle 1) can be further reduced, and the nozzle 1 is less likely to become an obstacle. Furthermore, even when it is detached from the container 2, if it is folded short, the storage space can be small, and the convenience is improved.

The first ring forming sides 1 which are alternately arranged
By making 2 shorter than the second ring forming side 13, it becomes difficult for the liquid to pool in the bellows portion 11 of the nozzle body 3. That is, by making the first ring forming side 12 shorter than the second ring forming side 13, the difference in the inclination angle of the second ring forming side 12 with the axis is smaller. The same applies to the inner wall of the bellows portion 11 of the nozzle body 3, that is, the liquid flows more easily on the second ring forming side 13. Therefore, when the nozzle 1 is attached to the opening of the container 2 and the liquid in the container 2 flows out, the tip (outflow portion 7) of the nozzle 1 is located below the mounting portion 6 in the direction of gravity. Since the second ring forming side 13 is disposed below the first ring forming side 12, when the nozzle body 3 is extended, liquid does not easily accumulate in the bellows portion. Further, when the nozzle body 3 is contracted, the first ring forming side 12 is folded inside the second ring forming side 13, so that both the first and second ring forming sides 12, 13 when the liquid flows out Since the bellows portion 11 is inclined downward, the liquid does not accumulate in the bellows portion 11.

Further, since the tip end cap 5 is attached to the outlet portion 7 of the nozzle body 3, the outlet 16 at the tip end of the nozzle 1 can be sealed. At this time, since the sealing piece 23 is provided in the tip cap 5,
The outlet 16 can be sealed more reliably, and the convenience is further improved. That is, if there is no sealing structure at the tip of the nozzle, the nozzle 1 is removed for a highly volatile liquid in the container 2 or a liquid that emits an unpleasant odor.
A separate sealing cap must be attached, which is troublesome. If the liquid is flammable, the nozzle 1 must be removed and replaced with a sealing cap for safety reasons. On the other hand, if the tip cap 5 is attached to the outflow portion 7 of the nozzle body 3, the outlet 16 of the nozzle 1 can be sealed even with the nozzle 1 attached, so that the airtightness is high. It can also handle storage of volatile or unpleasant odor liquids. Also, even in the event of the container 2 falling over, the tip cap 5 can prevent liquid leakage and prevent the contents from flowing out. If this is a flammable liquid, it is also advantageous from a disaster prevention point of view. Further, the connecting portion 21 is attached to the tip cap 5.
The engagement ring 20 is connected via the
Since 0 is engaged with the ring groove 18 of the nozzle body 3, even if the tip cap 5 is removed, the tip cap 5 does not fall off the nozzle body 3.
Convenience is further improved. That is, when replacing the nozzle 1 with another sealing cap, the number of separated parts increases, and the possibility of loss is increased. For example, when the container 2 is emptied with the nozzle attached, if the nozzle is left attached, it is necessary to store the sealing cap in another place, which increases the possibility of loss.
