Description

  The present invention relates to a dispensing container.

Conventionally, as described in, for example, Patent Document 1, a container body in which contents are stored, a head body that is attached to the mouth of the container body and has a communication hole that communicates with the inside of the container body; A pouring container is proposed comprising a slide member disposed on the head body so as to be slidable in a direction perpendicular to the container axis and having a pouring hole having a smaller diameter than the communicating hole. ing.
In such a pouring container, for example, when the remaining amount of the contents in the container main body is reduced, the slide member is slid to expose the communication hole to the outside, so that the diameter is larger than the pouring hole. The contents can be taken out from the communication hole.

JP 2011-73761 A

  However, in the conventional dispensing container, there is a possibility that the slide member is slid by an external force applied unexpectedly and the communication hole is exposed to the outside.

  The present invention has been made in view of the above-described problems, and a hole communicating with the inside of the container body and exposed to the outside is unexpectedly applied to the container body from the pouring hole by the external force. An object of the present invention is to provide a pouring container that can suppress inadvertent switching to another hole located inside the.

  The present invention employs the following means in order to solve the above problems. That is, the pouring container of the present invention includes a container main body in which contents are stored, a main body cap screwed into a mouth portion of the container main body and formed with a content pouring hole, and the main body cap. An upper cap that is detachably screwed to the outlet hole and covers the pouring hole, and a loosening direction of the upper cap around the container axis with respect to the main body cap, and a container shaft with respect to the mouth portion of the main body cap The dispensing container has the same loosening direction along the circumference, and an engagement cylinder is externally mounted on the mouth of the container body, and the engagement cylinder and the container body are engaged with each other. Accordingly, each of the engaging portions for restricting relative rotational movement of the engaging cylinder and the container main body in at least the loosening direction is formed separately, and the main body cap has the engaging cylinder radially outward. And go to the outer peripheral surface An enclosure cylinder is provided, and an engagement piece that is accommodated in the engagement cylinder and is connected via a weakened part that can be bent or broken is projected from the engagement cylinder. It is characterized by that.

In this case, the engaging portions formed separately on the engaging tube and the container main body engage with each other, and the engaging pieces of the engaging tube housed in the housing recess of the main body cap are on the inner peripheral edge of the housing recess. Since it abuts, the relative rotational movement of the body cap and the mouth in the loosening direction is restricted. Therefore, when the upper cap and the container main body are relatively moved in the loosening direction, the main cap is prevented from rotating together with the upper cap.
Then, when the engaging piece is bent or broken from the weakened portion as a starting point and separated from the housing recess, the relative movement of the main body cap and the engaging cylinder and thus the mouth portion in the loosening direction is restricted. The main body cap can be detached from the mouth portion.
That is, in order to detach the main body cap from the mouth portion, not only the engagement piece is detached from the housing recess, but also an operation of relatively rotating the main body cap and the mouth portion in the loosening direction is required. Therefore, it is possible to prevent a hole communicating with the inside of the container body and exposed to the outside from being inadvertently switched from the pouring hole to the opening of the mouth by an external force applied unexpectedly.
Thus, by detaching the main body cap from the mouth portion, for example, the contents in the container main body can be directly taken out from the mouth portion, or the main body cap and the container main body can be separated.

In the present invention, the opening torque required to remove the upper cap from the main body cap may be larger than the opening torque required to remove the main body cap from the mouth.
In this case, when the upper cap is rotated in the loosening direction with respect to the container main body with the engagement piece being detached from the receiving recess, the main body cap is opened while the main cap is screwed to the upper cap. Departed from the department. Therefore, after the engagement piece is detached from the housing recess, the upper cap is removed from the container body without separately performing the operation of removing the upper cap from the main body cap and the operation of removing the main body cap from the mouth. The main body cap can be detached from the mouth simply by rotating in the loosening direction, and the operability can be improved.

  According to the dispensing container according to the present invention, in order to detach the main body cap from the mouth portion, it is necessary to disengage the engaging piece from the housing recess, and further relatively rotate and move the main body cap and the mouth portion in the loosening direction. Therefore, it is possible to prevent the hole exposed to the outside from being inadvertently switched from the pouring hole to the opening of the mouth due to the external force applied unexpectedly.

In addition, an attachment projection 33A that engages with the attachment groove 17A protrudes radially inward from the lower end of the attachment cylinder 33. The lower cylinder part 32 and the attachment cylinder part 33 sandwich the upper end part of the inner cylinder part 17 and the cylindrical part 26 of the on-off valve 25 in the radial direction.

  The engagement cylinder 5 surrounds the threaded cylinder portion 16 of the mounting cylinder 11 from the radially outer side. Further, as shown in FIG. 3, a pair of second engaging portions 5 </ b> A protrudes radially inward from the lower end of the engaging cylinder 5. The second engaging portion 5A has a rectangular cross-sectional view, and the circumferential width of the second engaging portion 5A is equal to the end surface of the first engaging portion 3A in the tightening direction and the positioning protrusion. This is equivalent to the distance between the end face in the loosening direction of 3B. Therefore, the end surface in the loosening direction of the second engagement portion 5A is close to or abuts on the end surface of the first engagement portion 3A, and the end surface in the tightening direction of the second engagement portion 5A is the positioning protrusion 3B. It approaches or abuts the end face. Accordingly, the second engagement portion 5A is positioned in the circumferential direction with respect to the mouth portion 3. Further, as shown in FIG. 1, the second engaging portion 5 </ b> A is close to or in contact with the lower end of the screwed tube portion 16. Accordingly, the second engaging portion 5A is restricted from moving upward with respect to the mouth portion 3, and the engagement of the first and second engaging portions 3A, 5A is prevented from being released.

Moreover, the lower end part of the engagement cylinder 5 is surrounded by the cylindrical outer cylinder part 41 arrange | positioned on the radial direction outer side.
The outer cylinder portion 41 is disposed coaxially with the container axis O, and a concave portion 41A that is recessed downward from the upper end is formed in a portion of the outer cylinder portion 41 where the circumferential position coincides with the housing concave portion 15A. Is formed. Further, the inner peripheral edge of the recess 41 </ b> A in the outer cylinder portion 41 is connected to the lower end portion of the engagement cylinder 5 via the coupling portion 42. Further, the lower end of the engagement piece 44 is connected to the outer peripheral edge of the coupling portion 42 via a weakening portion 43 that can be bent or broken.
The engagement piece 44 is a plate-like member extending in the vertical direction, and both circumferential edges of the engagement piece 44 are in contact with the inner peripheral edge of the housing recess 15A. Therefore, the mounting cylinder 11 is positioned in the circumferential direction with respect to the engaging cylinder 5. Further, the upper end of the engagement piece 44 is a free end and protrudes upward from the upper end of the surrounding cylinder portion 15.

The upper cap 6 includes a top wall portion 51 having a circular shape in plan view, and a cylindrical peripheral wall portion 52 continuously provided downward from the radially outer side of the top wall portion 51.
On the inner peripheral surface of the lower end portion of the peripheral wall portion 52, a female screw portion that is screwed to the male screw portion of the inner cylinder portion 17 is formed, and below this female screw portion, the engagement protrusion 23A is formed. An engaging recess 52 </ b> A for engaging and positioning the upper cap 6 with respect to the mounting cylinder 11 in the circumferential direction is formed. Thus, when the engaging recess 52A engages with the engaging protrusion 23A, the maximum opening torque required when the peripheral wall 52 is detached from the inner cylinder 17 is the screwed cylinder 16 of the mounting cylinder 11. This is larger than the maximum opening torque required for removing the from the mouth 3.

Next, the usage method of the extraction container 1 of the above structures is demonstrated.
First, the upper cap 6 is rotated in the loosening direction with respect to the container body 2. Here, since the inner peripheral edge of the accommodation recess 15A in the loosening direction and the engagement piece 44 are in contact with each other, the mounting cylinder 11 is restricted from rotating in the loosening direction with respect to the engagement cylinder 5. Further, since the first engagement portion 3A of the container body 2 and the second engagement portion 5A of the engagement cylinder 5 are engaged, the engagement cylinder 5 rotates in the loosening direction with respect to the container body 2. Is regulated. Therefore, when the upper cap 6 is rotated with respect to the container main body 2 in the loosening direction, the main body cap 4 is prevented from rotating together with the upper cap 6.
Then, the upper cap 6 is released from the main body cap 4 by releasing the engagement between the engagement protrusion 23A and the engagement recess 52A and rotating in the loosening direction. Thereby, the pouring hole 12A of the pouring cylinder 12 is exposed to the outside.

  In addition, since the lower end of the threaded cylinder portion 16 is close to or in contact with the upper end of the second engagement portion 5A of the engagement cylinder 5, the upward movement of the engagement cylinder 5 with respect to the container body 2 is restricted. Is done. Therefore, for example, even if an upward external force is applied to the engagement cylinder 5 via the engagement piece 44, the first engagement portion 5A moves upward with respect to the first engagement portion 3A. The engagement between the engagement portion 3A and the second engagement portion 5A is prevented from being released.

For example, when the container main body 2 is gripped and the container main body 2 is squeezed and deformed with the pouring hole 12A exposed, the internal pressure of the container main body 2 rises and the valve body 27 of the on-off valve 25 rises and the valve seat Separated from the portion 24. Thereby, the contents in the container body 2 are discharged from the opening of the valve seat portion 24 through the inside of the extraction cylinder 12 and from the extraction hole 12A.
After appropriately pouring out the contents, the upper cap 6 is screwed onto the mounting cylinder 11.

Subsequently, for example, when the content in the container body 2 is low, the method of using the dispensing container 1 when it is desired to take out the contents from the opening of the mouth portion 3 having a diameter larger than the dispensing hole 12A. Will be explained.
First, as shown by an arrow A in FIG. 1, the engagement piece 44 is bent or broken starting from the weakened portion 43. At this time, since the engaging piece 44 is exposed to the outside from the upper cap 6, the engaging piece 44 can be bent or broken while the upper cap 6 is screwed to the mounting cylinder 11. Thereby, the engagement between the housing recess 15A of the main body cap 4 and the engagement piece 44 of the engagement cylinder 5 is released.

  Then, the upper cap 6 is rotated in the loosening direction with respect to the container body 2. Here, the maximum opening torque required when the peripheral wall portion 52 is detached from the inner tube portion 17 is larger than the maximum opening torque required when the screwed tube portion 16 is detached from the mouth portion 3, and the engagement is performed. Since the engagement between the protrusion 23A and the engagement recess 52A is not released, the main cap 4 is screwed to the upper cap 6 simply by rotating the upper cap 6 relative to the container main body 2 in the loosening direction. Thus, the main body cap 4 is detached from the mouth 3. Thereby, the opening of the mouth part 3 is exposed to the outside.

  Thereafter, in the same manner as described above, the container body 2 is gripped to squeeze deform the container body 2 or the contents are scooped out from the opening of the mouth part 3, for example, to remain in the mouth part 3 of the container body 2. The contents in the container main body 2 such as the contents being taken out are taken out. Here, when the main body cap 4 is detached from the mouth portion 3 after the engagement piece 44 is bent or broken, the opening of the mouth portion 3 having a diameter larger than the pouring hole 12A is exposed to the outside. The contents can be easily taken out. Thereby, it becomes easy to use up the contents in the container body 2. Even if the contents remain in the container body 2, the contents can be stored by screwing the body cap 4 to the mouth portion 3 again, so that the dispensing container 1 can be used easily.

According to the dispensing container 1 configured as described above, in order to disengage the main body cap 4 from the mouth portion 3, the engagement piece 44 is bent or broken, and the main body cap 4 is further moved away from the mouth portion 3. It is necessary to rotate in the loosening direction. Therefore, it is possible to prevent the hole communicating with the inside of the container body 2 and exposed to the outside from being inadvertently switched from the pouring hole 12 </ b> A to the opening of the mouth portion 3 due to the external force applied unexpectedly.
Further, after the engagement piece 44 is bent or broken, the main cap 4 can be detached from the mouth portion 3 simply by rotating the upper cap 6 in the loosening direction with respect to the container main body 2. Operability can be improved.
Here, the main body cap 4 and the container main body 2 can be separated. Furthermore, by removing the main body cap 4, the engagement piece 44 can be moved upward with respect to the container body 2, so that the engagement piece 44 can be separated from the container body 2.

In addition, this invention is not limited to the said embodiment, A various change can be added in the range which does not deviate from the meaning of this invention.
For example, the mounting cylinder and the dispensing cylinder are formed as separate members, but the mounting cylinder and the dispensing cylinder may be integrated.
The engagement cylinder is detachably mounted on the mouth portion, but may be non-detachable. Further, the engagement cylinder is restricted from moving in the vertical direction by the lower end of the screwed cylinder part approaching or abutting the upper end of the second engagement part, but the upper end of the engagement cylinder is used as the first connection part. The movement in the vertical direction may be restricted by approaching or abutting.
The engaging piece may have another shape as long as the main body cap can rotate in the loosening direction with respect to the engaging cylinder. Further, at least one engagement piece may be provided, and a plurality of engagement pieces may be provided. Similarly, the housing recess is formed as a slit that penetrates the surrounding cylinder, but may be a recess that does not penetrate the surrounding cylinder.
As an arrangement for making the opening torque required to remove the upper cap from the body cap larger than the opening torque required to remove the body cap from the mouth, the outer peripheral surface of the peripheral wall portion and the inner peripheral surface of the inner cylinder portion The friction coefficient between the inner peripheral surface of the screwed tube portion and the outer peripheral surface of the mouth portion is made larger, or the female screw portion of the peripheral wall portion is formed in the valley portion of the male screw portion of the inner tube portion. Other configurations may be employed, such as projecting a protruding portion for overcoming toward the radially outer side. Further, the opening torque required to remove the upper cap from the main body cap does not need to be larger than the opening torque required to remove the main body cap from the opening.
The upper cap may be configured to cover the engagement piece from the radially outer side.
Although the positioning protrusion is formed at the mouth portion, the positioning protrusion may not be formed.
The first and second engaging portions are formed in pairs, but it is sufficient that at least one is formed.
An opening / closing valve is provided inside the mounting cylinder, but the opening / closing valve may not be provided depending on the viscosity of the contents.
The container body may be a container body having another configuration such as a tube container. Further, the container body may not be squeezed and deformed depending on the contents.

  According to the present invention, the hole communicating with the inside of the container main body and exposed to the outside is changed from the pouring hole to another hole located inside the container main body by the external force applied unexpectedly. Industrial applicability is recognized for a dispensing container that can suppress inadvertent switching.
