JP 2002-326621 A

By the way, in the case of a refillable container that can be crushed in the container axial direction as described above, the mouth of the refill container is changed from the upright position to the mouth of the main container. It is efficient to connect and refill the contents while crushing while applying a compressive force to the refill container from above.
However, the above-mentioned conventional refill container has a problem that the contents spill out from the mouth when the mouth is turned upside down after being opened. On the contrary, there is a problem that even if the container is tilted or connected to the refill container in an inverted posture, if the contents remain in the container, the contents still spill out.

  This invention is made | formed in view of such a situation, and provides the refill container which can perform the refilling work efficiently, after suppressing the spill of the content at the time of refilling the content in this container.

As a means for solving the above-mentioned problems, the refill container according to the present invention is equipped with a container main body having a barrel portion that can be crushed in the axial direction of the container while the contents are accommodated, and the contents are mounted on the mouth of the container main body. A refilling container having a pouring member formed to pour out an object, wherein the pouring member is provided with an opening / closing valve for opening / closing the pouring port, and the opening / closing valve is provided with the pouring member. and the valve body for closing the infusion outlet being separable freely placed on the opening peripheral edge of the outlet, a support portion for supporting the valve body freely elastically displaced, and said valve body, the opening peripheral edge of the spout An annular outer flange portion that is disposed so as to be freely contacted and separated above, and a cylindrical portion that rises upward from an inner peripheral end of the outer flange portion, and an upper end of the cylindrical portion is attached to the mouth portion Abut the cap and open the spout when the cap is attached. Characterized in that it limited.

According to this configuration, the opening and closing valve that is elastically displaceable at the spout allows the contents in the container body to be poured when the contents are refilled simply by placing the container body in an inverted position with the spout facing downward. Outflow from the outlet is suppressed. For this reason, the spillage of the contents when the contents are refilled into the container can be suppressed.
In addition, when the body of the container body is crushed in the axial direction of the container while the spout is in communication with the inlet of the container, the internal pressure of the container acts on the on-off valve, and the valve body opens the spout. The support portion is elastically deformed so as to be separated from the peripheral edge, and the contents can be poured out from the spout.
At this time, the container body is crushed, for example, in the container axial direction, not in the radial direction, so that relative displacement between the main container and the refill container can be made difficult to occur at the time of refilling, and the internal pressure of the container body can be efficiently applied to the on-off valve. It is possible to exert well.

In the refill container according to the present invention, the container body has the first panel surface and the second panel surface alternately arranged in the circumferential direction, and each of the first panel surface and the second panel surface sandwiches the container shaft. A pair of the body portions provided in a rectangular shape in a cross-sectional view are provided so as to face each other,
A first bent line is formed along the circumferential direction on the first panel surface, and a second bent line extends along the container axis direction at a central portion in the circumferential direction on the second panel surface. And a ridgeline between the second panel surface and the first panel surface, extending in a forked manner so as to gradually expand in the circumferential direction from the upper end and the lower end of the second bent line, respectively, upward and downward. And the first folding line at the ridgeline between the first panel surface and the second panel surface, and arranged in the circumferential direction with the second folding line in between. A fourth bent line and a fifth bent line are formed extending from the portion where the height in the container axial direction coincides with the bent line toward the second bent line, and the fourth bent line is formed. The line extends along the circumferential direction, and the extension line intersects the second folding line The fifth bent line extends in a bifurcated shape so as to gradually spread in the container axial direction toward the second bent line, and is triangular in plan view with the second bent line. A bent panel surface having a shape is defined.

According to this configuration, when a compressive force in the container axial direction is applied to the container main body, the first panel surface is gradually bent along the first folding line by the compressive force, and the second panel surface is second. Since it bends gradually along a bending line-a 5th bending line, the whole trunk | drum is folded and begins to be crushed in the container axial direction.
At this time, the portion of the second panel surface where the fourth bent line is formed is bent along the fourth bent line extending in a straight line. Stress begins to concentrate at the portion where the second bent line intersects. On the other hand, about the part in which the 5th bending line is formed among the 2nd panel surfaces, it bends along the 5th bending line extended in V shape.
When the folding further proceeds, the second bent line is bent toward the fifth bent line with the intersection with the extended line of the fourth bent line as a center due to the stress concentration described above. Therefore, the folding panel surface can be folded starting from this bending point, whereby the folding of the entire body can be rapidly advanced. As a result, the container body can be crushed in the container axial direction.
In particular, the stress caused by folding can be actively concentrated on the second folding line, whereby the second folding line can be bent and the starting point of bending can be made at a fixed position. Therefore, the folding panel surface can be reliably folded at a fixed position, and the entire body portion can be folded stably. Therefore, the remaining volume can be uniformly crushed without leaving as much as possible.
Then, the crushing of the container body is performed smoothly, so that the opening operation of the valve body and the outflow of the contents subjected to the internal pressure are stabilized, and the contents can be refilled smoothly.

A cylindrical upper inner cylinder portion 14 that stands and forms the spout 9a is integrally formed. An annular seal portion 10 a that is in close contact with the inner periphery of the mouth portion 3 protrudes from the outer periphery of the upper portion of the outer cylinder portion 10. An annular pressing portion 10b that restricts upward movement of a holding cylinder portion 41, which will be described later, of the opening / closing valve 40 protrudes from the inner periphery of the upper end of the outer cylinder portion 10.

(Configuration of on-off valve)
As shown in FIGS. 7 and 8, the on-off valve 40 is a molded product made of synthetic resin, and includes a cylindrical holding cylinder portion 41 fitted into the inner periphery of the outer cylinder portion 10 of the pouring member 9, and a holding A plurality of arc-shaped support portions 42 connected to one end of the inner peripheral surface of the upper and lower intermediate positions of the cylindrical portion 41 as viewed in the container axis O direction, and other than the multiple support portions 42 arranged on the inner periphery of the holding cylindrical portion 41 A circular valve body 43 is integrally formed as viewed in the container axis O direction to connect the ends.

  Referring to FIG. 7, in the on-off valve 40, the upper outer periphery of the holding cylinder portion 41 is fitted into the upper inner periphery of the outer cylinder portion 10 of the extraction member 9, and the lower portion of the holding cylinder portion 41 is the extraction member 9. It is inserted into the gap between the lower part of the outer cylinder part 10 and the lower inner cylinder part 13, the lower end of the holding cylinder part 41 comes into contact with the upper surface of the lower short flange part 12 of the extraction member 9, and the upper end of the holding cylinder part 41 is poured. It is held in a state of being engaged below the pressing portion 10b of the output member 9. At this time, the outer peripheral lower surface (hereinafter referred to as a seal surface) 43a of the valve body 43 interferes (pressure contact) with the upper end surface (hereinafter referred to as the opening peripheral edge of the spout 9a) 9b of the upper inner cylindrical portion 14 of the extraction member 9. The valve body 43 elastically deforms the plurality of support portions 42 and is displaced upward.

  As a result, during normal times when there is no large input to the on-off valve 40, the valve body 43 is urged toward the opening peripheral edge 9b of the spout 9a by the elastic force of the plurality of support portions 42, and the seal surface 43a of the valve main body 43 is The spout 9a is closed close to 9b. On the other hand, when the internal pressure or the like of the blow container 2 acts on the valve main body 43, the valve main body 43 is separated from the opening peripheral edge 9b of the spout 9a and opens the spout 9a (see the right side in FIG. 9).

7, 8, the valve body 43 includes an annular outer flange portion 44 which is separable freely placed on the opening peripheral edge 9b of the spout 9a with connecting a plurality of support portions 42, the outer flange portion A cylindrical portion 45 erected upward from the inner peripheral end of 44; The upper end of the cylindrical portion 45 abuts on the lower end of the guide wall 8b protruding from the bottom surface of the top of the cap 8 attached to the mouth portion 3, and restricts the opening of the spout 9a when the cap 8 is attached.

  The support portion 42 has an arc shape extending in the circumferential direction, and connects the distal end portion in the clockwise direction of FIG. 8 to the outer periphery of the valve main body 43, and holds the distal end portion in the counterclockwise direction of FIG. 41 is connected to the inner periphery of 41. A plurality (three in the present embodiment) of the support portions 42 are arranged between the holding cylinder portion 41 and the valve main body 43 at intervals in the circumferential direction. The plurality of support portions 42 support the valve body 43 so as to be displaceable in the container axis O direction, and the spout 9 a can be opened and closed by the displacement of the valve body 43.

(Use of refill containers)
Next, the case where the contents of the refill container 1 configured as described above are poured out will be described with reference to FIG. In the present embodiment, a description will be given by taking as an example a case where, for example, contents having a high viscosity are poured into a container 51 partially illustrated and refilled.

First, the cap 8 is removed from the mouth 3, and the refill container 1 is turned upside down, and then the mouth 3 of the refill container 1 is inserted into the mouth 52 of the main container 51 in the upright posture.
At this time, as shown on the left side of FIG. 9, the opening / closing valve 40 of the refill container 1 moves the valve main body 43 over the opening peripheral edge 9b of the spout 9a only by receiving the weight of the contents. The leakage of contents from the spout 9a is suppressed.

For this reason, when the refill container 1 is turned upside down, the contents do not spill out from the spout 9a, and it is difficult to close the spout 9a with fingers or change the posture of the container 51. The mouth 3 of the refill container 1 can be inserted into the mouth 52 of the main container 51 without requiring any work.
When the mouth part 3 of the refill container 1 is inserted into the mouth part 52 of the main container 51, the stopper wall 3 b of the mouth part 3 of the refill container 1 comes into contact with the open end of the mouth part 52 of the main container 51 and is refilled. The amount of insertion of the mouth 3 of the container 1 is limited.

Subsequently, by applying a compressive force to the refill container 1 along the container axis O direction, the body portion 6 of the refill container 1 is crushed as shown in FIGS. Extrude to 51 side and refill contents.
At this time, the refill container 1 in the inverted posture can be made independent by inserting the mouth 3 of the refill container 1 into the mouth 52 of the main container 51. Further, the insertion amount of the mouth portion 3 of the refill container 1 is limited by the stopper wall 3b, so that when the compressive force is applied from above to the bottom portion 5 of the refill container 1 in the inverted posture, the mouth portion 3 of the refill container 1 is provided. However, the operator can easily apply the compressive force from above, so that the body 6 of the refill container 1 can be crushed efficiently and easily. .

  The crushing of the body 6 will be described in detail. When a compressive force is applied in the container axis O direction, the first panel surface 20 is gradually radially inward along the first folding line 30 by the compressive force. And the second panel surface 21 is gradually bent along the second bent line 31 to the fifth bent line 34, so that the body portion 6 composed of the upper panel unit 6A and the lower panel unit 6B is formed. The whole is folded and begins to be crushed in the container axis O direction.

  At this time, since the fourth bent line 33 and the fifth bent line 34 having different shapes are formed on the second panel surface 21 with the second bent line 31 in between, the second bent line 31 is The folding method of the both sides in the circumferential direction is different.

  That is, the portion of the second panel surface 21 where the fourth bent line 33 is formed bends along the fourth bent line 33 extending in a straight line. Stress begins to concentrate at the portion where the extension line and the second bent line 31 intersect. On the other hand, the portion of the second panel surface 21 where the fifth bent line 34 is formed bends along the fifth bent line 34 extending in a V shape.

  When the folding progresses, due to the stress concentration described above, the second bent line 31 is formed in a dogleg shape around the intersection with the extended line of the fourth bent line 33 toward the fifth bent line 34 side. Bend (see FIG. 6). Therefore, the folding panel surface 36 can be folded starting from this bending point, whereby the folding of the entire body portion 6 can be rapidly advanced. As a result, the refill container 1 can be crushed in the container axis O direction, and the contents can be refilled into the container 51.

  In particular, the stress caused by folding can be actively concentrated on the second folding line 31, whereby the second folding line 31 is bent to make the starting point of bending at a fixed position. Therefore, the folding panel surface 36 can be reliably folded at a fixed position, and the entire body 6 can be folded stably. Therefore, the remaining volume can be crushed uniformly without leaving as much as possible, and the contents can be refilled to the container 51 side without leaving waste.

  Moreover, since it can be crushed uniformly, even a highly viscous content can be easily pushed out to the main container 51 side, and the refilling operation can be performed smoothly. Further, since the remaining volume can be uniformly crushed without leaving as much as possible, it is possible to reduce the volume when the refill container 1 is discarded.

  In addition, since the ridge line L between the first panel surface 20 and the second panel surface 21 is chamfered by the tapered cut surface 37, the first panel surface 20 and the second panel surface 21 are respectively bent lines 31 to 34. Easy to fold along. Therefore, the refill container 1 can be crushed with less resistance.

  Further, since the formation positions of the fourth folding line 33 and the fifth folding line 34 are alternately arranged in the upper panel unit 6A and the lower panel unit 6B, as shown in FIG. At the time of folding, each second folding line 31 can be bent in the opposite direction. Therefore, it can prevent that the thickness of the folded folding panel surface 36 overlaps with the container axis | shaft O direction, and can crush the refill container 1 with sufficient balance.

  When compressing force is applied to the refill container 1 and the body portion 6 is crushed, the internal pressure of the refill container 1 increases as the internal volume decreases, and as shown on the right side of FIG. 43 is displaced upward (downward in FIG. 9) against the urging force of the plurality of support portions 42. Thereby, the clearance gap D arises between the valve main body 43 and the opening periphery 9b of the spout 9a, the spout 9a is opened, and the spout 9a of the refill container 1 and the inlet 52a of the main container 51 communicate with each other. The contents of the refill container 1 can be transferred to the main container 51. At this time, the crushing of the body portion 6 of the refill container 1 is stably performed in a balanced manner, so that the opening operation of the valve main body 43 is stabilized, and the contents can be refilled smoothly.

  When the application of the compressive force to the refill container 1 is stopped to interrupt the refilling operation of the contents, the increase in the internal pressure of the container disappears and the elastic deformation of the trunk portion 6 partially returns to the container from the spout 9a. Try to inhale outside air. However, in the present embodiment, since the application of the compressive force is stopped and the increase in the container internal pressure is eliminated, the on-off valve 40 closes the spout 9a. , And the spillage of the contents from the spout 9a when the refill container 1 is removed from the main container 51 can be suppressed.

  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, in the above embodiment, the body 6 is configured by connecting the panel units 6A and 6B in two upper and lower stages, but the panel unit may be connected in three or more stages. Even in this case, the body 6 can be subdivided for each panel unit and can be stably and reliably folded. Therefore, even if the body 6 is a long large container, it is easy to perform smooth crushing.
What is necessary is just to form as the 1st bending line 30-the 5th bending line 34 by providing a convex rib, a concave rib, or a level | step difference. Each of the bent lines 30 to 34 is not limited to a continuous straight line, and may be formed in an intermittent straight line. The bent lines are connected to each other, or the connecting portions of the bent lines and the ridge lines are connected or disconnected. Either may be used.

The on-off valve 40 is a so-called three-point valve that allows the valve body 43 to be displaced by the valve body 43 and the three support portions 42 to open and close the spout 9a. The valve main body 43 may be supported by the support part 42 or the valve main body 43 may be supported by four or more support parts 42, and the valve main body 43 is displaced in the container axis O direction to open and close the spout 9a. The on-off valve 40 having various configurations may be used.
Although the cap 8 is screwed onto the mouth 3, the lid may be connected to the mouth 3 via a weakened portion that can be broken. At the time of refilling, the mouth portion 3 of the refill container 1 is inserted into the mouth portion 52 of the main container 51. However, the mouth portion 52 of the main container 51 is inserted into the mouth portion 3 of the refill container 1 or both mouth portions 3 are inserted. , 52 may be abutted against each other.
