Description

  The present invention relates to a discharge member attached to a container body in which an opening is formed and a liquid is accommodated, and a container including the discharge member.

  Conventionally, various containers containing liquids such as chemicals have been proposed. For example, in the container described in Patent Document 1, a discharge member is attached to an opening of a container body that stores liquid. A cylindrical discharge portion is attached to the upper surface of the discharge member, and a liquid discharge hole is formed at the tip of the discharge member. Further, a cap is attached to the discharge member, and a closing portion for closing the discharge hole is attached to the inside of the cap. Thereby, when the cap is closed, the discharge hole is closed by the closing portion.

Japanese Patent No. 5730172

  However, in the container as described above, it cannot be said that the discharge hole is sufficiently closed by the closing portion, and it is assumed that the liquid leaks from the discharge hole even when the cap is closed. Accordingly, there has been a demand for a discharge member that can reliably close the discharge hole. The present invention has been made to solve the above problems, and an object of the present invention is to provide a discharge member that can reliably prevent leakage of liquid from the discharge hole, and a container including the discharge member. .

  The present invention is a discharge member attached to a container body in which an opening is formed and a liquid is accommodated, and a base surface portion that is attached to the opening and exposed to the outside is formed, and the base surface portion includes An attachment portion formed with a communication hole communicating with the inside, a discharge portion that protrudes from a base surface portion of the attachment portion and discharges liquid in the container body, and is attached to the attachment portion. A cap that closes the discharge hole so that it can be opened and closed, and the discharge part has a cylindrical main body part with one end communicating with the communication hole, and a lid part that closes the other end of the main body part, The cap is connected to the attachment portion via a hinge portion, and includes a support portion that covers the base surface portion, and a closure portion that is attached to the support portion and covers the discharge hole of the discharge portion. The support part is centered on the hinge part. The closing portion is configured to pivot between a first position where the discharge hole is covered and a second position where the discharge hole is opened, and the support portion is moved from the second position to the second position. In the process of moving to the position 1, the closing portion passes through a third position where the closing portion contacts the lid portion of the discharge portion, and the support portion is moved from the third position to the first position by an external force. It is configured to move to the position.

  According to this configuration, when the cap is closed, the cap is once positioned at the third position, and then is displaced to the first position by applying a force. At this time, the closing part is arranged at a position covering the discharge part mainly against the elastic force of the hinge part. Therefore, since the closing portion closes the discharge hole in a state where the elastic force is applied, the closing portion is in a state of being in close contact with the outer peripheral surface of the discharging portion. Therefore, it is possible to reliably prevent liquid from leaking from the discharge hole. Note that “covering the discharge hole” may be such that the closed portion does not need to be in direct contact with the periphery of the discharge hole, and the discharge hole is sealed by the closed portion.

  In the discharge member, the closing portion may be formed in a cylindrical shape so that the discharge portion is fitted when the support portion is in the first position. Thereby, the perimeter of the discharge part can be surrounded by the closing part, and the discharge hole can be reliably closed. Therefore, it is possible to reliably prevent liquid leakage.

  In each of the discharge members, the discharge hole can be formed in the main body. Thereby, the discharge hole can be reliably closed by the closing portion.

  In each of the discharge members, the outer surface of the cover portion of the discharge portion can be formed in a spherical shape. Thereby, a closing part can slide to the outer surface of a cover part, and can move to the position which closes a discharge hole smoothly.

  The container which concerns on this invention is equipped with the container main body and the discharge member in any one of the above-mentioned attached to the opening of the said container main body.

  According to the present invention, it is possible to reliably prevent liquid leakage from the discharge hole.

And a cap 6 that is attached via the two. These are integrally formed. Hereinafter, each part will be described in detail.

<2-1. Mounting part>
The attachment portion 3 includes a cylindrical attachment main body 31. The mounting body 31 has a lower end opened and an upper end closed by a plate-like base surface portion 32. The inner wall surface of the mounting body 31 is formed with a female screw (not shown) that is screwed into the male screw of the neck portion 14 of the container body 1. A through hole 33 is formed in the center of the base surface portion 32, and this through hole 33 communicates with the internal space of the attachment main body 31 and the internal space of the container main body 1 through the neck portion 14.

<2-2. Discharge unit>
The discharge unit 4 includes a cylindrical main body 41, the lower end of the main body 41 is connected to the periphery of the through hole 33 of the base surface 32, and the upper end is closed by a hemispherical lid 42. . And the inner wall surface of this cover part 42 is also formed in the hemispherical shape. A circular discharge hole 43 is formed near the upper end of the main body 41, that is, below the lid 42. The discharge hole 43 extends perpendicularly to the outer peripheral surface of the main body 41 and communicates the internal space of the main body 41 with the outside. Therefore, the liquid in the internal space of the container main body 1 is discharged from the discharge hole 43 through the neck portion 14, the through hole 33 of the base surface portion 32, and the main body portion 41 of the discharge portion 4.

  An inner diameter A of the main body 41 of the discharge unit 4 can be set to 1 to 15 mm, for example. Further, the inner diameter B of the discharge hole 43 can be set to 1 to 5 mm, for example.

In this way, the chemical solution can be discharged smoothly.

<2-3. Cap>
Next, the cap 6 will be described. The cap 6 includes a circular support portion 61 connected to the attachment portion 3 via the hinge portion 5 and a cylindrical closing portion 62 attached to the lower surface of the support portion 61.

  The support portion 61 includes a circular substrate 611 and a peripheral edge 612 that extends downward from the peripheral edge of the substrate 611. As shown in FIG. 2, the cap 6 is opened by a hinge portion 5 described later, and an open position (second position) where the base surface portion 32 of the mounting portion 3 is exposed to the outside, and a base as shown in FIG. 5. A closed position (first position) covering the surface portion 32 can be taken.

  As shown in FIGS. 2 to 5, the substrate 611 has substantially the same shape as the base surface portion 32 of the mounting portion 3, and when the cap 6 is closed, the lower end of the peripheral edge portion 612 is the base surface portion 32. It comes in contact with the periphery. Thereby, a space is formed between the base surface portion 32 and the support portion 61, and the above-described discharge portion 4 is accommodated in this space. Further, notches 63 and 64 in which a hinge portion 5 described later is disposed are formed in a part of the substrate 611 and the peripheral edge portion 612. The notch includes a first notch 63 extending from the vicinity of the edge of the substrate 611 to the vicinity of the center, and a second notch 64 that is continuous with the first notch 63 and extends from the upper end to the lower end of the peripheral edge 612. It is configured. That is, the notches 63 and 64 are formed in an L shape extending from the substrate 611 to the peripheral edge 612.

  Further, the closing portion 62 described above is attached to the center of the substrate 611 of the support portion 61. The lower end of the closing part 62 is open, and the discharge part 4 is inserted into the closing part 62 when the support part 61 is in the closed position. At this time, the inner wall surface of the closing portion 62 is in contact with the outer peripheral surface of the discharging portion 4 so that the discharging hole 43 is closed.

  As will be described in detail later, in the process in which the cap 6 is displaced from the open position to the closed position, as shown in FIG. 4, the lower end portion of the closing portion 62 once comes into contact with the lid portion 42 of the discharge portion 4, and from there When an external force is applied, the discharge part 4 is accommodated in the closing part 62. As described above, a position where the lower end portion of the closing portion 62 contacts the lid portion 42 of the discharging portion 4 is referred to as a temporarily closed position (third position).

<2-4. Hinge>
The hinge part 5 includes a central piece 51 and a pair of end pieces 52 and 53 arranged on both sides thereof. The end pieces 52 and 53 are formed in a band shape and connect the lower end of the peripheral edge portion 612 of the support portion 61 and the peripheral edge of the base surface portion 32 of the attachment portion 3. Are arranged at predetermined intervals. Thin portions 521 and 531 are formed near the centers of the end pieces 52 and 53, respectively. The thin portions 521 and 531 are bent so that the cap 6 is connected to the mounting portion 3 and closed from the open position. Can be displaced into position. As shown in FIG. 2, in the open position, the cap 6 is open to an angle of about 120 degrees with respect to the base surface portion 32 of the mounting portion 3.

  The central piece 51 includes a band-shaped first portion 511 and a second portion 512, and these two portions 511 and 512 are connected in an L shape so as to be elastically deformable. That is, the angle formed by the first part 511 and the second part 512 is about 90 degrees in a normal state, but is expanded to an angle larger than 90 degrees by elastic deformation.

  The end portion of the first portion 511 is connected to the end portion on the center side of the support portion 61 in the first notch 63 of the cap 6 via the thin portion 514, and the first portion 511 is connected to the support portion 61. And can be swung. On the other hand, the end of the second part 512 is connected to the outer peripheral surface of the attachment main body 31 of the attachment part 3 via the thin part 515, and the second part 512 can swing with respect to the attachment main body 31. ing.

  When the cap 6 is in the closed position, the first part 511 is accommodated in the first notch 63 and the second part 512 is accommodated in the second notch 64. In this state, the angle of the first part 511 and the second part 512 is in a normal state. From here, in the process of moving the cap 6 to the open position, the thin portion 514 of the first part 511 is shown in FIG. In this way, the first portion 511 and the second portion 512 are elastically expanded so as to have an angle larger than 90 degrees to an intermediate position located immediately above the thin portion 515 of the second portion 512. This state is referred to as an open state. When the intermediate position is passed and the cap 6 is displaced to the open position, the positions of both ends of the central piece 51 are set so that the angles of the first part 511 and the second part 512 return to the normal state.

  Therefore, between the closed position and the intermediate position, the angle between the first part 511 and the second part 512 is expanded from the normal state against the elastic force, but external force is applied to the cap 6 so as to exceed the intermediate position. When acted, the central piece 51 is restored by the elastic force from the open state to the normal state, and the cap 6 is automatically displaced to the open position.

  Similarly, even when displacing from the closed position to the open position, when an external force is applied so as to exceed the intermediate position, the cap 6 is automatically displaced to the temporary closed position described above by the elastic force.

<2-5. Material>
Although the material which forms the discharge member 2 is not specifically limited, For example, it can form with resin materials, such as a polyethylene terephthalate, polyethylene, a polypropylene.

<2-6. Displacement of cap between temporarily closed position and closed position>
Next, the displacement of the cap 6 between the temporarily closed position and the closed position will be described. As described above, the cap 6 is automatically displaced from the intermediate position to the temporarily closed position by elastic deformation of the central piece 51 of the hinge portion 5. In the temporarily closed position, as shown in FIG. 4, the lower end portion of the closing portion 62 comes into contact with the lid portion 42 of the discharging portion 4. More specifically, of the lower end portion of the closing portion 62, the edge portion opposite to the hinge portion 5 is in contact with the inclined surface on the discharge hole 43 side on the upper surface of the lid portion 42. When the support portion 61 of the cap 6 is pressed from above in this state, the hinge portion 5 is elastically deformed, so that the support portion 61 moves substantially horizontally toward the discharge hole 43 side. As a result, the lower end portion of the closing portion 62 slides on the inclined surface of the lid portion 42 and reaches the vicinity of the lower end of the discharge portion 4 through the discharge hole 43. As a result, the closing part 62 covers the outer peripheral surface of the discharging part 4, the discharging hole 43 is closed, and the cap 6 is arranged at the closed position.

<3. How to use the container>
First, the cap 6 is displaced from the closed position to the open position, and the discharge unit 4 is exposed. Next, the outer peripheral surface of the container body 1 is gripped by hand, and the container is tilted to such an extent that the discharge hole 43 of the discharge unit 4 faces downward. Thereby, the chemical solution in the container body 1 is discharged from the discharge hole 43 through the neck portion 14 and the discharge portion 4.

<4. Features>
As described above, according to this embodiment, since the inner wall surface of the lid portion 42 is provided above the discharge hole 43 in the discharge portion 4, the chemical solution is discharged from the container body 1 when the container is tilted. Flows into section 4. Then, as shown in FIG. 7, most of the chemical liquid is discharged from the discharge hole 43 that is directed downward after once colliding with the inner wall surface of the lid portion 42 extending in the flow direction due to the momentum of the chemical liquid flow. . Therefore, for example, it can prevent that a chemical | medical solution is discharged | emitted vigorously compared with the discharge hole being provided in the front-end | tip of the discharge part. Therefore, the discharge direction of the chemical solution can be controlled. In particular, since the inner wall surface of the lid part 42 is formed in a hemispherical shape, it is possible to form a flow that smoothly returns the chemical liquid that has collided with the lid part 42 to the discharge hole 43 side.

  Further, when the cap 6 is closed, the cap 6 is once positioned at the temporarily closed position, and then is displaced to the closed position by applying a force. At this time, the closing part 62 is disposed at a position covering the discharge part 4 mainly against the elastic force of the hinge part 5. Therefore, the closing part 62 closes the discharge hole 43 in a state where the elastic force is applied. In particular, since the discharge hole 43 is formed on the outer peripheral surface of the main body 41 of the discharge portion 4, the inner wall surface of the closing portion 62 is in close contact with the peripheral edge of the discharge hole 43. Therefore, the chemical liquid can be reliably prevented from leaking from the discharge hole 43.

<5. Modification>
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to this, A various change is possible unless it deviates from the meaning. Note that the following modifications can be combined as appropriate.

<5-1>
The position of the discharge hole 43 is not particularly limited. For example, the discharge hole 43 can be arranged at least on the through hole side of the top of the inner wall surface of the lid portion 42. Therefore, as shown in FIG. 8, it may be provided on the lid portion 42. That is, when the chemical liquid is discharged, it is sufficient that the chemical liquid once collides with the inner wall surface of the lid portion 42 and then can be discharged from the discharge hole 43. However, the present invention is not limited to this. It can also be provided on the further tip side of 42. In the case as shown in FIG. 8, the peripheral edge of the discharge hole 43 does not contact the closing part 62, but at least the closing part 62 firmly contacts the outer peripheral surface of the main body part 41 of the discharge part 4. In this state, the closed portion 62 is hermetically sealed. Therefore, leakage of the chemical solution can be prevented.

<5-2>
The lid part 42 does not have to be a spherical surface, and can have various forms such as a flat shape, a conical shape, and a pyramid shape. However, if an inclined surface is formed on the outer surface of the lid portion 42, the closing portion 62 can easily slide on the outer surface of the lid portion 42 as described above, and can be smoothly displaced from the temporarily closed position to the closed position. Further, the main body 41 of the discharge unit 4 can also be formed in a rectangular tube shape instead of a cylindrical shape.

<5-3>
The shape of the closing portion 62 is not particularly limited. For example, as shown in FIG. 9, the closing portion 62 may be formed in a circular arc shape so as to be in contact with the outer peripheral surface of the main body portion 41 of the discharge portion 4 on the discharge hole 43 side. it can. That is, the closing part 62 only needs to be formed so as to cover the discharge hole 43 at least on the side opposite to the hinge part 5.

<5-4>
The structure of the hinge part 5 is not specifically limited, Aspects other than the said embodiment may be sufficient. That is, it is sufficient that at least the cap 6 and the mounting portion 3 are connected so that the cap 6 can be displaced between the closed position and the open position. Moreover, the hinge part 5 and the cap 6 can also be comprised by a member different from an attaching part.

<5-5>
In the above embodiment, when the cap 6 is displaced from the temporarily closed position to the closed position, the closing portion 62 is formed so as to cover the discharge portion 4 mainly by elastic deformation of the hinge portion 5. It is also possible to displace the temporary closing position to the closing position by elastic deformation of the closing part 62 and the discharging part 4 other than the above. Therefore, it is sufficient that at least one of the closing portion 62, the discharge portion 4, and the hinge portion 5 is elastically deformable.

<5-6>
The shape of the cap 6 is not particularly limited as long as at least the support portion 61 and the closing portion 62 are provided. For example, the support portion 61 does not necessarily have a structure that covers the base surface portion 32 of the attachment portion 3, and may have any structure as long as the closing portion 62 can be attached.

<5-7>
The shape of the container main body 1 is not particularly limited as long as at least the opening 15 to which the attachment portion 3 is attached may be formed. Therefore, the attachment method of the attachment part 3 is not particularly limited. In the above embodiment, the attachment portion 3 and the neck portion 14 are fixed by screw fitting. For example, while forming a female screw on the inner peripheral surface of the neck portion 14, a male screw is provided on the outer peripheral surface of the attachment portion 3. They can be formed and screwed together. Alternatively, the attachment portion 3 can be fixed to the inner wall surface of the neck portion 14 by caulking.

<5-8>
What is accommodated in the inside of the container main body 1 is not limited to a chemical | medical solution, A various kind of liquid can be accommodated. Further, the level of the viscosity of the liquid is not particularly limited as long as it has fluidity at 25 ° C.
