Description

[Detailed description of the invention] <Industrial application field> The invention relates to a liquid storage container.
In particular, the present invention relates to a container suitable for storing hair shampoo, conditioner, liquid detergent, etc.

《Prior Art》 Conventionally available containers of this type include an inner stopper with a small hole drilled in the upper end of the neck of the container body, and a cap screwed onto the outer periphery of the neck. This is the most common type, but it is inconvenient when washing hair, etc., because it requires the cap to be attached and removed before use. There is also a cap that is hinged to one end of the inner plug, and the cap and the inner plug are elastically engaged and detached using a protrusion, but this type has a problem with the sealing performance when the cap is closed.
If the container were to topple over, there was a risk that the contents would leak out.

In addition, in the container shown in Utility Model Application No. 55-121062, an inner cap 3 is fitted around the inner periphery of the neck, a protrusion 5 is provided at the center of the bottom of the inner cap 3, and a communication port 4 is provided around the protrusion 5. There is a through hole 1 that serves as a discharge port.
The lower half of the nozzle 2 having a
When the nozzle descends, the protrusion closes the lower part of the through hole. On the other hand, a rotary operating body 11 is disposed around the outer periphery of the inner cap, nozzle, etc. so as to cover the inner cap, the nozzle, etc., and this rotary operating body is fixedly integrated with the nozzle at its upper end.

Then, by rotating the rotary operating body, the nozzle also rotates, and the nozzle and rotary operating body are both raised by the inner circumference of the inner cap and the screw of the nozzle, and the lower part of the through hole of the nozzle and the protrusion are separated and penetrated. The hole is designed to be opened. This container is convenient in that there is no need to attach or remove the cap from the container, and also has excellent sealing performance when closed.

<<Problems to be solved by the invention>> However, in the above configuration, the blocked part of the discharge port is located inside the neck, and since the nozzle is screwed into the neck, it is difficult to see whether the discharge port is completely blocked. Or it is difficult to tell whether it is open or not.
Therefore, there is a problem in that people often forget to tighten the screws after use.

In addition, in the above configuration, the through hole of the nozzle that serves as the discharge path for the contents is long and narrow, and the through hole is opened and closed by a short and small protrusion provided at its lower end. Afterwards, the contents tend to remain in the through hole and solidify, making it difficult to discharge new contents during subsequent use or creating a large amount of unsanitary residue.

Further, as described above, since the rotary operating body rises together with the nozzle, the lower end of the rotary operating body separates from the container body. Therefore, the contents that leak out during use, etc. will travel along the outer circumferential surface of the rotary operating body and reach the bottom end, and when the rotary operating body is lowered in this state, the leaked contents will be transferred between the rotary operating body and the container body. It stays in between. In particular, if the rotary operating body is raised too high and a complete gap is created between the rotary operating body and the container, the rotary operating body is more likely to remain in the internal space. The remaining contents tend to attract dust and dirt, which is undesirable from a sanitary standpoint.

This idea was made in view of the problems mentioned above.
The purpose of this is to be able to open and close the dispensing port for the contents with a simple operation, and to check the opening/closing status of the dispensing hole at a glance.Furthermore, there is little residue inside the dispensing port, and the remaining amount of dispensing material does not reach the outside surface of the container. To provide a hygienically excellent liquid storage container that does not stagnate.

<<Means for Solving the Problems>> In order to achieve the above object, the liquid storage container according to the present invention includes a stopper having a protrusion that extends greatly upward and a through hole at the upper end opening of the neck of the container body. an inner stopper is unrotatably attached to the outer periphery of the neck, a nozzle member is arranged between the inner stopper and the stopper body so as to be movable in the vertical direction, and the nozzle member has a diameter larger than that of the protrusion. A relatively long large diameter hole is formed to define a pouring passage between the projection and a relatively short small diameter hole is formed to have a smaller diameter than the upper end of the projection and define a discharge port. an outer plug is attached to the outer periphery of the inner plug so that the outer plug is rotatable but not movable up and down, and only the nozzle member is moved in the vertical direction with respect to the plug body by rotation of the outer plug, The nozzle member is engaged with either the outer plug or the inner plug in a non-rotatable and vertically slidable manner via an engaging means, and the other inner plug or the outer plug is The nozzle member is rotatably engaged through a thread to form a means for moving the nozzle member in the vertical direction, and when the nozzle member is in the downward position, the tip thereof is in contact with the upper surface of the outer plug. The inner surface of the nozzle member comes into contact with the protrusion to block the discharge port, and at a position above the nozzle member, the blockage is released and the tip of the nozzle member contacts the outer plug. It is characterized by being protruded further upwards.

<<Operation>> According to the above structure of the present invention, at the lower position of the nozzle member, the tip of the nozzle member is flush with the upper surface of the outer plug, and the discharge port is blocked. When the outer plug is turned from this state, the nozzle member does not engage with either the outer plug or the inner plug in order to move only this member vertically relative to the plug body by the rotation of the outer plug. The nozzle member is engaged with the other inner plug or outer plug so as to be unrotatable and slidable in the vertical direction through a coupling means, and is rotatably engaged with the other inner plug or outer plug through a thread. As it rotates and moves upward, only the nozzle member protrudes upward from the top surface of the outer plug, and the protrusion separates from the inner periphery of the discharge port, forming a gap between the protrusion and the discharge port, and the discharge port is unblocked. The liquid in the container can be taken out from the through hole through the spout passage and the discharge port of the nozzle.

<<Example>> Hereinafter, a liquid substance storage container according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 show a container according to a first embodiment of the present invention, and reference numeral 1 in the figures is a container main body made of synthetic resin, etc., and inside the container main body there is a container containing shampoo, conditioner, etc. It is designed to contain liquid substances. A hollow cylindrical neck 2 is integrally formed at the center of the upper end of the container body 1.
A plug body 3 is attached to the upper end opening by fitting its flange portion 4 to the outer periphery of the neck portion 2. It has a cylindrical protrusion 5 with a tapered surface 5a formed on the edge, and a plurality of through holes 6 bored around the protrusion. An annular convex portion 7 is provided on the outer circumferential surface of the neck portion 2, and the annular convex portion 7 of the inner plug 8 engages with the annular convex portion 7, so that the inner plug is fitted to the outside of the neck portion 2, and the lower end of the inner plug 8 The plurality of ribs 10 formed on the neck portion 2 and the groove 11 of the neck portion 2 are fitted together to prevent the inner stopper from rotating relative to the neck portion.

A flange 12 is provided at the upper part of the inner plug 8,
A thread 13 is formed on the inner surface of the flange, and a thread 15 of the nozzle member 14 is screwed into this thread 13 so as to be rotatably engaged therewith. The nozzle member 14 is arranged to be movable in the vertical direction in the space between the protrusion 5 and the inner plug 8, and its lower part 16 is formed to have a large diameter and is in contact with the inner circumferential surface of the inner plug 8. A tip 17 above the strip 15 can protrude upward from the inner plug 8. The inside of the nozzle member 14 is formed hollow, with a relatively long large diameter hole 18a having a larger diameter than the projection 5 and widening at the lower part, and a relatively short and small hole 18a having a smaller diameter than the projection at the upper end. The small diameter hole 18b is continuous with the step part 18c, and a content (liquid material) pouring passage is defined between the large diameter hole 18 and the projection 5. Defining the discharge port and at the lower position of the nozzle member 14 shown in FIG.
The discharge port is blocked by the stepped portion 18c coming into contact with the upper end tapered surface 5a of the protrusion 5.

An outer plug 19 is disposed on the outside of the inner plug 8, and the outer plug is rotatable relative to the inner plug by fitting the annular groove 20 of the inner plug with the annular convex portion 21 of the outer plug. and is installed so that it cannot move up and down. The center part of the upper end of the outer plug 19 is open, and the tip part 1 of the nozzle member 14 is inserted into the opening.
7 is located, and the longitudinal rib 23 of the distal end engages with the longitudinal groove 22 formed on the inner surface of the opening, thereby forming an engaging means, and the distal end 17, and therefore also The nozzle member 14 is non-rotatable with respect to the outer plug 19 and is slidable in the vertical direction. Therefore,
As will be described later, when the outer plug 19 is rotated, the nozzle member 14 also rotates, and the threads 13, 15
The nozzle member is adapted to move vertically relative to the stopper through the screw engagement between the longitudinal grooves 22 and the longitudinal ribs 23, and when the nozzle member 14 is in the lower position, the tip thereof 17 becomes substantially flush with the upper surface of the outer plug 19, and the inner surface of the nozzle member 14 comes into contact with the protrusion 5 to block the discharge port, while at a position above the nozzle member 14, the blocking is released and the nozzle member The tip 17 of the outer plug 14 is projected upward from the outer plug 19, and accordingly, the tip 17 moves in and out of the opening of the outer plug 19.

FIG. 4 shows a liquid storage container according to a second embodiment of the present invention. Only the parts different from the above-mentioned embodiments will be explained. In this embodiment, the nozzle member 1
A thread 15' is formed on the tip 17' of the nozzle member 14', which is threadedly engaged with a thread 13' formed on the inner surface of the opening of the outer plug 19'. It is rotatably engaged with 19'. On the other hand, a pair of vertical grooves 22'-22' are formed on the inner surface of the flange 12' of the inner plug 18', and a pair of vertical ribs 22' are provided in the vertical grooves at approximately the center of the nozzle member 14'.
3'-23' are engaged, and the nozzle member is inserted into the inner plug 8'.
It constitutes an engagement means that is non-rotatable but slidable in the vertical direction. Therefore, when the outer plug 19' is rotated, a relative rotation occurs between it and the nozzle member 14', and the threads 13' and 15' and the longitudinal groove 2 are rotated.
2' and the longitudinal rib 23', the nozzle member is adapted to move vertically relative to the plug body. The protrusion 5' of the plug body 3' has an upper end surface that is connected to the outer plug 1.
The nozzle member 14' shown in FIG.
In the lower position of the projection, the tapered surface 5'a of the projection forms a tapered surface 2 defining the upper end outlet of the nozzle member.
4 and blocks the discharge port, and this blocking is released when the nozzle member 14' moves upward.
The rest of the configuration is the same as that of the first embodiment, so redundant explanation will be omitted.

In the first embodiment of the present invention, when the nozzle member 14 is in the lower position shown in FIG. At the same time, the tip end 17 of the nozzle member is flush with the upper surface of the outer plug 19. From this state, grasp the container body 1 and
When the outer plug 19 is rotated in the direction shown by arrow a in the figure, the nozzle member 14 rotates together with it, while the inner plug 8 is prevented from rotating by the neck 2, so that the thread of the nozzle member 15 is the thread 13 of the inner plug.
, and as a result, the nozzle member 1
4 moves upward. Due to this movement, the stepped portion 1
8c is separated from the protrusion 5 and the above-mentioned interruption is released,
The contents inside the container body 1 are transferred from the through hole 6 of the stopper 3 to the nozzle member 14 and the protrusion 5 as shown by the arrow b.
The liquid can be dispensed from the discharge port of the nozzle member through a dispensing passage defined between them. In this state, the tip end 17 of the nozzle member 14 is
It protrudes upward from the opening of 9. After using the contents, rotate the outer stopper 19 in the opposite direction of arrow a until the tip 17 is completely retracted into the opening.
The discharge port may be blocked by the stepped portion 18c.

Further, in the embodiment shown in FIG. 4, since the rotation of the nozzle member 14' is restricted by the inner plug 8', when the outer plug 19' is rotated, the nozzle member 14' A relative rotation occurs between the threads 13' and 15' and the longitudinal groove 22' and the longitudinal rib 2.
3' causes the nozzle member to move in the vertical direction. In the state shown in FIG. 4 in which the nozzle member 14' is in the lower position, the tapered surface 5'a of the protrusion 5' and the tapered surface 2 of the nozzle member
4 is in contact with the discharge port, and when the nozzle member 14' moves upward, the tapered surface 24
is separated from the protrusion 5', the blockage is released, and the contents can be discharged.

<Effect of the invention> As described above, the liquid storage container according to the invention has the following advantages:
The outlet for the contents can be opened and closed with an extremely simple one-touch operation by simply rotating the outer plug, making it easy to use when washing hair, etc., and when closed, the inner surface of the nozzle member closes to the plug body. The sealing performance is also good because the discharge port is blocked by contacting the protrusion.

Furthermore, since the open/closed state of the discharge port can be determined by whether or not the tip of the nozzle member protrudes from the outer plug, there is no risk of forgetting to tighten it after use, and it can also be tightened when not in use (when closed). Since the nozzle member is retracted, the design can be made smarter, and there is no risk of injury to the human body or foreign matter adhering to the nozzle member.

In addition, the protrusion of the plug body is formed to be long and large, and the discharge port located above it is formed to be short and small.
There is little content remaining in the discharge port, and even if it hardens, it will hardly make it difficult to discharge the content afterwards.

Furthermore, since the outer stopper only rotates and does not move upward, the contents discharged during use get trapped between the outer stopper and the container body and accumulate, unlike in the conventional case.
This solves the problem of dirt and grime adhering to it, making it unsanitary.
