Description

  The present invention relates to a discharge container.

As one of the discharge containers of this type, a double container type in which an inner container is accommodated (included) inside an outer container, and a pump part having a pressing head that is biased upward is attached to the mouth of the inner container. Is known (see Patent Document 1).
The discharge container will be described in detail. The inner container is formed in a bottomed cylindrical shape having a mouth portion having a neck ring at the upper end. When the inner container is accommodated in the outer container, the mouth portion projects from the upper opening formed in the top wall of the outer container to the outside of the outer container. And the pump part is mounted | worn with this projecting opening | mouth part.

By the way, when the inner container is accommodated in the outer container, the neck ring of the inner container is fitted into the cylindrical piece suspended from the lower surface of the top wall of the outer container. At this time, the neck ring is formed in a regular octagonal shape in plan view, and the cylinder piece is also formed in a regular octagonal shape in plan view in accordance with the shape of the neck ring. Therefore, the neck ring is prevented from rotating in the circumferential direction when fitted into the cylinder piece.
That is, the inner container is in a state in which rotation in the circumferential direction is restricted with respect to the outer container. For this reason, when the pump part is attached to and detached from the mouth part of the inner container, it is possible to prevent the inner container from being connected together in the circumferential direction. Accordingly, the pump unit can be easily attached and detached.

JP 2003-40304 A

Among the double-container-type discharge containers as described above, in recent years, it is known that the remaining amount of the contents filled in the inner container can be easily confirmed.
Specifically, a transparent or translucent window portion is formed in a part of the inner container so that the inside can be visually recognized. Thereby, the inside of an inner container can be visually recognized from an outer side only through a window part. On the other hand, the outer container is formed of a transparent or translucent material. Thereby, the window part of the inner container accommodated inside can be visually recognized through this container from the outer side of an outer container. That is, the remaining amount of the contents can be easily confirmed by looking through the window of the outer container and the inner container.

  By the way, while the outer container has a role of protecting the inner container, it also plays a role as an outer package of the product itself. For this reason, it is common that various kinds of information related to products, contents, and the like are displayed on the outer peripheral surface of the outer container by printing, sticking a sticker, or the like. However, if the window portion of the inner container is located on the back side on which these various types of information are displayed, the display is obstructed and it becomes difficult to clearly see the window portion. Therefore, when assembling the inner container and the outer container, it is necessary to set so that the window portion is at a position outside the display.

  In this regard, the conventional double-container type discharge container is simply designed so that the inner container does not rotate in the circumferential direction with respect to the outer container, so when assembling the inner container and the outer container, In addition, it is necessary to pay attention so that the window is not hidden behind the various information displayed on the outer container. Therefore, it takes time to assemble and causes a reduction in manufacturing efficiency.

  The present invention has been made in consideration of such circumstances, and its purpose is to easily and reliably set the position of the window portion of the inner container with respect to the outer container at a predetermined position in the circumferential direction. An object of the present invention is to provide a discharge container that can simultaneously prevent the inner container from rotating relative to the outer container.

In order to achieve the above object, the present invention provides the following means.
(1) A discharge container according to the present invention has a transparent outer container in which a top wall having an upper opening is connected to the upper end of an outer cylinder, and a mouth at the upper end of the inner cylinder filled with contents. A transparent inner container accommodated in the outer container so that the mouth projects upward through the upper opening, and the inner cylinder is formed by a transfer film formed on the outer peripheral surface. A window portion that is partitioned and allows the inside of the inner container to be visible is formed, the mouth portion is provided with a first fitting portion at one place in the circumferential direction, and the upper opening portion is provided in the circumferential direction. A second fitting portion into which the first fitting portion is fitted is provided at one place.

In the discharge container according to the present invention, when checking the remaining amount of the contents, the remaining amount can be easily confirmed from the outside of the outer container by looking through the window of the outer container and the inner container. . By the way, the 1st fitting part is provided in one place in the circumferential direction in the mouth part of the inner container, and this 1st fitting part is the 2nd fitting also provided in one place in the circumferential direction of the upper opening part.

That is, the outer container and the inner container can be reliably aligned in a predetermined direction. As a result, the position of the window portion of the inner container relative to the outer container can be easily and reliably set at a predetermined position in the circumferential direction.
As a result, the visual recognition area for viewing through the window portion of the inner container can be determined on the outer peripheral surface of the outer container, so that various information on products, contents, etc. can be transmitted to the outer periphery of the outer container without obstructing the view of the window portion. It is possible to display on the surface. In particular, unlike the prior art, it is not necessary to assemble while paying attention so that the window is not hidden behind the display. Therefore, efficient assembly can be performed in a short time.

  Moreover, the rotation to the circumferential direction of an inner container is controlled because the 1st fitting part and the 2nd fitting part fit, and the rotation prevention of the inner container with respect to an outer container is achieved. Therefore, even when a pump part, a cap, or the like attached to the mouth part of the inner container is attached or detached from the mouth part, it is possible to prevent the inner container from being linked together. Therefore, the attachment / detachment operation can be easily performed.

(2) The discharge container according to the present invention is the discharge container according to the present invention, wherein the inner container has a shoulder portion between the inner cylinder and the mouth portion, An annular wall is formed so as to surround the periphery of the upper opening and is in contact with the shoulder to restrict the upward movement of the inner container relative to the outer container.

  In the discharge container according to the present invention, when the inner container and the outer container are assembled, the mouth portion protrudes through the upper opening portion, and the first fitting portion provided in the mouth portion is provided in the upper opening portion. When fitted into the joint, the annular wall formed on the lower surface of the top wall comes into contact with the shoulder. Thereby, further upward movement of the inner container can be restricted. Therefore, the outer container and the inner container can be assembled with high accuracy so that the mouth portion reliably protrudes by the determined height, and the assembling accuracy can be increased.

(3) The discharge container according to the present invention is the discharge container according to the present invention, wherein the shoulder is provided with a protrusion that bulges outward, and the shoulder is in contact with the annular wall. A locking portion for locking the protrusion is provided.

  In the discharge container according to the present invention, when the annular wall comes into contact with the shoulder, the protrusion provided on the shoulder is not simply brought into contact with the engaging portion provided on the annular wall. . Thereby, a shoulder part contact | abuts to an annular wall, without sliding in the circumferential direction. That is, the inner container can be prevented from rotating with respect to the outer container by restricting the rotation of the inner container in the circumferential direction between the shoulder portion and the contact portion. Therefore, it is possible to more effectively prevent the inner container from rotating together during the attachment / detachment operation.

(4) In the discharge container according to the present invention, the discharge container according to the present invention is formed on the inner peripheral surface of the upper opening so as to swell radially inward, and supports the mouth from below. And a step portion for restricting the downward movement of the inner container relative to the outer container is formed.

  In the discharge container according to the present invention, when the inner container and the outer container are assembled, the mouth portion protrudes through the upper opening portion, and the first fitting portion provided in the mouth portion is provided in the second opening portion. When fitted into the joint, the mouth is supported from below by the step. Thereby, the downward movement of the inner container can be restricted. Therefore, the outer container and the inner container can be assembled with high accuracy while preventing the inner container from falling into the outer container, and the assembly accuracy can be increased.

(5) The discharge container according to the present invention is the discharge container of the present invention described above, wherein the inner container is provided with an inner dish fitted to the inner peripheral surface of the inner cylinder so as to be slidable up and down. A pump unit that discharges the contents by a vertical movement of a pressing head biased upward by the unit is mounted.

  In the discharge container according to the present invention, the content filled in the inner cylinder of the inner container can be discharged by pressing down the pressing head of the pump unit against the upward biasing force. Further, when the depression of the pressing head is released, the contents in the inner cylinder can be sucked into the pump unit and can be prepared for the next discharge. At this time, the inner tray moves upward in the inner cylinder due to pressure fluctuations accompanying the movement of the contents, and promotes the discharge of the contents.

  According to the discharge container of the present invention, the position of the window portion of the inner container with respect to the outer container can be easily and reliably set at a predetermined position in the circumferential direction, and the inner container is prevented from rotating with respect to the outer container at the same time. be able to.

  A transfer film M is formed on the outer peripheral surface of the inner cylinder 10 over substantially the entire surface, but as shown in FIG. 4, only one portion in the circumferential direction is partitioned (formed) by the transfer film M. A window portion 13 is formed, and the inside of the inner container 3 is visible. That is, the inside of the inner container 3 can be visually recognized through the window portion 13. The window portion 13 of the present embodiment is formed in a vertically long rectangular shape having a length L and a lateral width W from the upper end portion to the lower end portion of the inner cylinder 10.

As shown in FIGS. 3 to 6, the mouth portion 12 includes a screw portion 15 to which the mounting cylinder 20 of the pump portion 5 is screwed, and a flange portion 16 formed between the screw portion 15 and the shoulder portion 11. And. The flange portion 16 is an annular member extending outward in the radial direction, and is a cut portion 16a having a surface cut at one place in the circumferential direction.
The cut portion 16a is formed so as to be positioned on the opposite side of the window portion 13 described above, and functions as a first fitting portion that is fitted to a restriction plate 44 described later. That is, in the present embodiment, the window portion 13 and the cut portion 16a are formed so as to face each other with the central axis O interposed therebetween.

  By the way, the shoulder 11 is formed with three protrusions 17, 18, and 19 that bulge outward. Of the three protrusions 17, 18, 19, the protrusion 17 is formed in a vertically long plate shape along the central axis O just below the cut portion 16 a. The remaining two projecting portions 18 and 19 are formed at positions 90 degrees clockwise and 90 degrees counterclockwise from the projecting portion 17, respectively, along the slope of the shoulder 11 in the radial direction.

The pressing head 21 is combined with the mounting cylinder 20 so as to be vertically movable above the mounting cylinder 20. The pressing head 21 is finished, for example, in a smooth and slightly rounded shape with extra corners, and the nozzle 22 is formed on a part of the side surface.

  Further, in the cylinder cylinder 23, the push-down head 21 in the upward biased state is pushed down to lower the cylinder cylinder 23, and pressurize the contents W stored in the cylinder cylinder 23 to put the contents W in the cylinder cylinder 23. A piston member is disposed that flows to the nozzle 22 side or rises when the pressed down pressing head 21 returns upward, and negatively reduces the pressure inside the cylinder cylinder 23 to suck up the contents W from the inner cylinder 10. Yes.

The lower end of the cylinder cylinder 23 closes when the pressure in the cylinder cylinder 23 rises, shuts off the inside of the inner cylinder 10 and the inside of the cylinder cylinder 23, and opens when the pressure in the cylinder cylinder 23 becomes negative. A suction valve (not shown) that connects the inside of the inner cylinder 10 and the inside of the cylinder cylinder 23 is provided.
Further, the pressing head 21 and the mounting cylinder 20 of the pump unit 5 configured as described above are covered and protected by an overcap 25 that is detachably attached when the discharge container 1 is not used.

Next, the inner dish 4 will be described.
As shown in FIGS. 1 and 2, the inner tray 4 is fitted to the inner peripheral surface of the inner cylinder 10 so as to be slidable in the vertical direction. It moves up in the cylinder 10. The inner tray 4 includes a cylindrical outer cylinder portion 30 that contacts the inner peripheral surface of the inner cylinder 10, and a partition member 31 that closes the opening of the outer cylinder portion 30 and confines the contents W in the inner cylinder 10. It is configured.
The outer cylinder part 30 is designed so that the middle part is slightly recessed inward in the radial direction, and the upper end side and the lower end side are in contact with the inner peripheral surface of the inner cylinder 10 over the entire circumference. Therefore, it is in contact with the inner peripheral surface with an appropriate frictional force, and can smoothly slide and move.
Note that the present invention is not limited to this, and the entire outer peripheral surface of the outer cylinder portion 30 contacts the inner peripheral surface of the inner cylinder 10 or a contact portion that extends over the entire periphery is formed only at one location on the outer peripheral surface of the outer cylinder portion 30. You can do it.

  The partition member 31 of the present embodiment is integrally formed with the inner cylinder portion 32 and the flange portion 33. The inner cylinder part 32 is disposed inside the outer cylinder part 30, and is formed by a cylindrical inner peripheral wall 32a and a partition wall 32b that is formed at a substantially intermediate portion of the inner peripheral wall 32a and closes the opening of the inner peripheral wall 32a. It is integrally formed. The flange portion 33 is formed in an annular shape, and integrally connects the upper end portion of the inner cylinder portion 32, that is, the upper end of the inner peripheral wall 32 a and the upper end of the outer cylinder portion 30 over the entire circumference.

Next, the outer container 2 will be described.
The outer container 2 is a container formed of a transparent or translucent material, and protects the inner container 3 and serves as an outer package of the discharge container 1. As shown in FIGS. 7 to 9, the outer container 2 includes an outer cylinder 40 formed in a cylindrical shape around the central axis O, and a top wall 41 connected to the upper end portion of the outer cylinder 40, It consists of
FIG. 7 is a cross-sectional view of the outer container 2. FIG. 8 is a top view of the outer container 2. 9 is a cross-sectional arrow DD view of the outer container 2 shown in FIG.

On the outer peripheral surface of the outer cylinder 40, various types of information (not shown) regarding the product, contents W, and the like are displayed by printing, sticking a sticker, and the like. As shown in FIG. 2, a bottom portion 42 is fitted and fixed to the lower end portion of the outer cylinder 40 to close the opening on the lower end portion side.
The bottom portion 42 is formed with a clearance hole 42 a for communicating the gap space S between the inner tray 4 and the bottom portion 42 with the outside. Thereby, even if the inner tray 4 rises in the inner cylinder 10, it is possible to suppress the gap space S from becoming a negative pressure, and the inner tray 4 can be moved up smoothly.

As shown in FIGS. 7 to 9, an upper opening 43 that projects the mouth 12 of the inner container 3 upward is formed at a substantially central portion of the top wall 41. The opening size of the upper opening 43 of the present embodiment is designed so that the inner peripheral surface is in contact with the outer peripheral surface of the flange portion 16, and the flange portion 16 is placed inside the upper opening 43 as shown in FIG. 2. It is possible to arrange them with almost no gap.
By the way, as shown in FIGS. 7 to 9, the upper opening 43 has a restriction plate (second fitting portion) 44 in which the cut portion 16 a of the flange portion 16 is fitted in one place in the circumferential direction. It is formed so as to close the part. As a result, the flange portion 16 cannot be disposed inside the upper opening 43 unless the positions of the cut portion 16a and the regulating plate 44 are aligned and fitted together.
That is, the cut portion 16a and the regulation plate 44 play a role of regulating the rotation of the inner container 3 in the circumferential direction and positioning the inner container 3 and the outer container 2 in one predetermined direction.

  A step 45 is formed on the inner peripheral surface of the upper opening 43 so as to swell radially inward. In this embodiment, the step part 45 is formed in four places. These step portions 45 play a role of regulating the downward movement of the inner container 3 relative to the outer container 2 by supporting the flange portion 16 from the lower side when the flange portion 16 is disposed inside the upper opening 43. .

An annular wall 46 is formed on the lower surface of the top wall 41 so as to surround the upper opening 43 so as to hang down toward the bottom 42. As shown in FIGS. 1 and 2, the annular wall 46 is designed so that the lower end abuts against the shoulder 11 of the outer container 2 when the flange portion 16 is disposed inside the upper opening 43. ing. Thereby, the upward movement of the inner container 3 relative to the outer container 2 can be restricted, and the flange portion 16 is prevented from moving upward from the upper opening 43.
That is, the inner container 3 is reliably positioned in the direction of the central axis O with respect to the outer container 2 by the above-described stepped portion 45 and the annular wall 46, and the threaded portion 15 is reliably protruded by a predetermined amount. ing.

Further, as shown in FIGS. 7 to 9, the annular wall 46 is provided with a locking groove 47 and a recess 48 for locking the protrusions 17, 18, and 19 of the inner container 3 described above. First, on the inner peripheral surface of the annular wall 46, two protrusions 49 protruding inward in the radial direction are formed so as to be aligned in a circumferentially spaced state at a position hidden under the restriction plate 44. . The space formed between the two protrusions 49 is used as the locking groove 47. When the flange portion 16 is arranged inside the upper opening 43, the protrusion 17 is fitted and locked. It has come to be.
In addition, a recess 48 is formed at the lower end of the annular wall 46 at a position 90 degrees clockwise and 90 degrees counterclockwise from the locking groove 47. That is, the recess 48 is formed so as to face each other with the central axis O interposed therebetween. When the flange portion 16 is disposed inside the upper opening 43, the protrusions 18 and 19 are fitted and locked in the recesses 48, respectively.

Next, the case where the contents W are discharged using the discharge container 1 configured as described above will be described.
In this case, as shown in FIG. 1, the pressing head 21 of the pump unit 5 is pushed down with a force against the upward biasing force. Then, the piston member moves down in the cylinder cylinder 23. Thereby, the contents W stored in the cylinder cylinder 23 are pressurized, and the suction valve blocks the inside of the cylinder cylinder 23 and the inside of the inner cylinder 10. As a result, the pressurized content W moves to the nozzle 22. As a result, the contents W can be discharged to the outside.

  On the other hand, when the depression of the push-down head 21 is released, the push-down head 21 is biased upward by the force of an elastic member such as a coil spring, and thus returns to the original position. Therefore, the piston member moves up in the cylinder cylinder 23. Thereby, the pressure in the cylinder cylinder 23 is reduced to a negative pressure, and the suction valve communicates the inside of the cylinder cylinder 23 with the inside of the inner cylinder 10. Therefore, the contents W filled in the inner cylinder 10 are sucked into the cylinder cylinder 23. As a result, the contents W can be stored again in the cylinder cylinder 23 and can be prepared for the next discharge.

  In addition, since the inner cylinder 10 is negatively pressured as the contents W are reduced due to siphoning, the inner tray 4 moves up in the inner cylinder 10. As a result, the suction of the contents W can be promoted, and even the highly viscous contents W can be surely sucked into the cylinder cylinder 23.

  As described above, the contents W filled in the inner container 3 can be used while being discharged by a predetermined amount as necessary. In addition, when checking the remaining amount of the contents W during use, the remaining amount can be easily confirmed from the outside of the outer container 2 by looking through the window 13 of the outer container 2 and the inner container 3. Can do.

Next, a procedure for assembling and manufacturing the discharge container 1 will be briefly described.
First, after setting the inner dish 4 inside the inner container 3, the inner container 3 is inserted into the outer container 2 and the both containers 2 and 3 are combined. Next, after combining the containers 2 and 3, the bottom 42 is fitted and fixed to the lower end of the outer container 2. Next, after filling the inner container 3 with the content W, the pump part 5 is mounted by screwing the mounting cylinder 20 of the pump part 5 onto the screw part 15 of the inner container 3 protruding from the outer container 2. . In this way, the discharge container 1 can be assembled.

  By the way, the flange portion 16 of the inner container 3 is formed with a cut portion 16a at one place in the circumferential direction, and the upper opening 43 of the outer container 2 is formed with a regulating plate 44 for fitting the cut portion 16a. . Therefore, when combining the inner container 3 and the outer container 2, the flange portion 16 cannot be disposed inside the upper opening 43 unless the position of the cut portion 16 a and the position of the restriction plate 44 are matched. Therefore, the outer container 2 and the inner container 3 can be assembled in the same determined direction. That is, the inner container 3 and the outer container 2 can be reliably aligned in a predetermined direction. As a result, the position of the window portion 13 of the inner container 3 relative to the outer container 2 can be easily and reliably set at a predetermined position in the circumferential direction.

  Thereby, since the visual recognition area | region for seeing through the window part 13 of the inner container 3 can be decided on the outer peripheral surface of the outer container 2, various information regarding goods, the content W, etc., without interrupting the visual field of the window part 13 Can be displayed on the outer peripheral surface of the outer container 2. In particular, unlike the conventional case, it is not necessary to assemble while paying attention so that the window portion 13 is not hidden behind the display. Therefore, efficient assembly can be performed in a short time.

  Further, when the inner container 3 and the outer container 2 are combined, the flange portion 16 is positioned inside the upper opening 43 in a state where the cut portion 16a and the regulation plate 44 are fitted, so the circumferential direction of the inner container 3 The inner container 3 is prevented from rotating relative to the outer container 2. Therefore, even if the pump part 5 is detached from the mouth part 12, it is possible to prevent the inner containers 3 from being connected together. Therefore, the attaching / detaching operation of the pump unit 5 can be easily performed.

  Further, when the inner container 3 and the outer container 2 are combined, when the flange portion 16 is positioned inside the upper opening 43 and the cut portion 16a and the regulation plate 44 are fitted, as shown in FIG. Two annular walls 46 abut against the shoulder 11 of the inner container 3. Thereby, further upward movement of the inner container 3 can be restricted. Moreover, since the flange portion 16 is supported from the lower side by the step portion 45, the downward movement of the inner container 3 can also be restricted. As a result, the outer container 2 and the inner container 3 are prevented from projecting the screw part 15 of the mouth part 12 by a predetermined height and preventing the inner container 3 from falling into the outer container 2. Can be assembled with high precision. Therefore, the assembly accuracy can be increased.

  Further, when the annular wall 46 abuts against the shoulder portion 11, the protrusions 17, 18, and 19 provided on the shoulder portion 11 are not simply abutted, but the locking grooves 47 and the recesses provided on the annular wall 46. 48 are respectively locked. Thereby, the shoulder part 11 contacts the annular wall 46 without sliding in the circumferential direction. That is, the rotation of the inner container 3 in the circumferential direction can also be restricted between the shoulder portion 11 and the annular wall 46 to prevent the inner container 3 from rotating relative to the outer container 2. Therefore, it is possible to more effectively prevent the inner container 3 from co-rotating when the pump unit 5 is attached or detached.

  As described above, according to the discharge container 1 of the present embodiment, the position of the window 13 of the inner container 3 with respect to the outer container 2 can be easily and reliably set at a predetermined position in the circumferential direction. The inner container 3 can be prevented from rotating with respect to the outer container 2 at the same time.

  The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, the configuration of the pump unit 5 described above is an example, and the design may be changed as appropriate. For example, a general discharge pump that does not use the inner tray 4 or a former pump that discharges the contents W in a foam form may be added to the configuration, and the contents W may be discharged in a mist form. It does not matter as a spray pump.

Further, although the window of the inner container 3 is formed in a vertically long rectangular shape, it may be formed in a vertically long elliptical shape or may be formed in a vertically long triangular shape, and the shape and number thereof are not limited.
Moreover, in the said embodiment, although the outer container 2 and the inner container 3 were formed with the transparent or semi-transparent material, the inside should just be visually recognized, for example, is formed with the material whose light transmittance is 40% or 80%. It doesn't matter.

Moreover, in the said embodiment, while the rotation to the circumferential direction of the inner container 3 is controlled with the cut part 16a formed in the flange part 16, and the control plate 44 formed in the upper opening part 43, the inner container 3 and the outer container However, the present invention is not limited to this case, and various configurations can be adopted as long as positioning in one direction is possible.
That is, the inner container 3 and the outer container include a first fitting portion provided at one place in the circumferential direction on the mouth portion 12 side and a second fitting portion provided at one place in the circumferential direction on the upper opening 43 side. 2 can be configured in any direction, the first fitting portion and the second fitting portion may be configured in any way.
