Description

  The present invention relates to a discharge container for discharging contents to the outside.

2. Description of the Related Art Conventionally, in a container in which liquid contents are stored, a container provided with an open / close mechanism using a manual valve body is known in order to prevent the contents from spilling when the container falls (see Patent Document 1). ).
In this container, the discharge port (spout port) and the air hole are simultaneously sealed from the same direction by the urging force of the spring acting in the same direction, and the button using the air hole is pressed against the urging of the spring. In addition, an opening / closing mechanism is provided in which the discharge port and the air hole are simultaneously opened to discharge the contents.

Utility Model Registration No. 3078012

  However, in the case of the container having the opening / closing mechanism, it is necessary to perform a manual opening / closing operation such as pressing a button every time the contents are discharged. Therefore, an open / close structure that does not require such an operation has been desired.

  This invention is made | formed in view of such a situation, The objective is to provide the discharge container which can discharge the content easily, without performing special operation.

In order to achieve the above object, the present invention provides the following means.
(1) A discharge container according to the present invention is equipped with a delamination type container body in which contents are stored and an inner layer is detachably laminated with respect to an outer layer, and a mouth of the container body. An outflow opening communicating with the inside is overlapped on the top wall portion so as to cover the outflow opening from above with a top-like cylindrical discharge cap formed on the top wall portion, and is positioned radially outside the outflow opening. A film whose outer peripheral edge is sealed to the top wall along the circumferential direction, and the outer peripheral edge of the film is formed with a non-seal part in which the seal is partially released. The seal portion and the top wall portion define a discharge port for discharging the contents flowing out from the outflow opening, and a neck portion located between the shoulder portion of the container body and the mouth portion includes an inner portion. A pressing deformation portion that can be pressed and deformed is formed in the direction.

In the discharge container according to the present invention, when the container body is tilted, the contents contained therein flow into the outflow opening of the discharge cap, and outflow while pushing up the film onto the top wall from the outflow opening. Then, the film is pressed and deformed in a direction away from the top wall by its own weight, and swells into a dome shape that protrudes upward. Thereby, the clearance gap between a ceiling wall part and a film becomes a discharge path connected with a discharge outlet. Accordingly, the contents flowing out from the outflow opening can be guided to the discharge port through this discharge path and discharged from the discharge port to the outside.
When the container body is returned to a posture in which the weight of the contents is not applied to the film after the discharge is completed, the pressing force applied to the film is released, and the film that has been deformed into a dome shape returns to the original state. In close contact with the top wall. Therefore, the outflow opening is closed again by the film and the discharge port is closed. Thereby, the sealing property of a container body is securable.

Thus, according to the discharge container according to the present invention, since the discharge can be performed by a simple method of tilting the container body and deforming the film by the weight of the contents, the discharge operation can be easily performed without performing a special operation. It is easy to use.
By the way, when the contents are discharged, the inner layer of the container body gradually peels from the outer layer and starts to undergo volume reduction deformation. Therefore, intrusion of outside air into the inside of the container body is suppressed, quality deterioration of the contents can be prevented, and the contents can be discharged smoothly.

Moreover, even when the remaining amount of the content is reduced, the remaining content can be discharged smoothly, and it is easy to use up without leaving the content wastefully. That is, when the remaining amount of the contents decreases, it is difficult to push up the film by its own weight even if the container body is tilted. In addition, volume reduction deformation of the inner layer is unlikely to occur at the neck and mouth.
Then, the pressure deformation part currently formed in the neck part of a container body is pressed with a fingertip etc., and it press-deforms so that it may dent inward. Thereby, the container internal pressure (internal pressure of the inner layer) by squeezing the neck portion can be increased. Then, this increased internal pressure acts to push the film outward. Therefore, it is possible to assist the force with which a small amount of content pushes up the film by its own weight, and it is possible to define a discharge path connecting the outflow opening and the discharge port.
As a result, even a small amount of contents can be discharged smoothly, and it is easy to use up without leaving the contents.

(2) A discharge container according to the present invention is the discharge container according to the present invention, wherein the discharge cap is attached to the mouth portion and has a first communication passage communicating with the inside of the container body; A discharge head that is mounted so as to be relatively movable with respect to the cap body, has a top wall portion, and has a second communication passage that communicates with the outflow opening, and the inside of the container body and the outflow opening Are switched to a communication state or a shut-off state through the first communication path and the second communication path in accordance with the relative movement of the discharge head.

In the discharge container according to the present invention, at the stage of use, the discharge head is moved relative to the cap body among the cap body and the discharge head constituting the discharge cap. Thereby, the inside of a container body and the outflow opening will be in the state connected through the 1st communicating path and the 2nd communicating path. Therefore, the contents can be discharged by tilting the container body.
When the storage is performed after the discharge is completed, the discharge head is moved relative to the cap body again to return to the original state. Thereby, the inside of the container body and the outflow opening which were communicating previously can be shut off. Therefore, even if the container body is tilted by mistake, the contents can be prevented from flowing out from the outflow opening.
Thus, since the distribution route to the outflow opening can be communicated or blocked according to the use situation, it is difficult to discharge the contents when not intended.

(3) A discharge container according to the present invention is a discharge container according to the present invention, wherein the container body is detachably fitted, and includes a bottomed cylindrical stand that supports the container body. Has an elliptical shape in cross section, and the bottom is formed in a convex curved surface.

In the discharge container according to the present invention, the body portion of the container body is formed in an elliptical shape in a cross-sectional view, and the bottom portion is formed in a convex curved surface shape toward the lower side. Therefore, the boundary portion between the body portion and the bottom portion of the container body is smoothly curved with a large curvature. That is, it is possible to prevent a bent portion having a small curvature from appearing at a boundary portion between the trunk portion and the bottom portion. Therefore, the inner layer of the container body can be peeled off from the outer layer with less resistance as the contents are discharged. Therefore, the inner layer can be deformed and reduced more reliably.
Moreover, even if the bottom is formed in a convex curved surface shape, the container body can be supported in an upright state by fitting the container body into the stand. Therefore, it is difficult to cause a problem that the container body falls and the contents leak from the discharge port.

(4) In the discharge container according to the present invention, in the discharge container of the present invention described above, a grip opening that exposes a part of the body portion of the container body is formed in the peripheral wall portion of the stand. It is characterized by.

  In the discharge container according to the present invention, the body portion of the container body can be gripped through the opening even when the container body is still fitted in the stand. Therefore, the container body can be tilted together with the stand without removing the container body from the stand, and the contents can be easily discharged.

(5) The discharge container according to the present invention is the discharge container according to the present invention, wherein the peripheral wall portion of the stand is formed with an inwardly recessed finger pad portion, and the finger body portion of the container body includes the finger An engagement portion that engages with the abutting portion and restricts the movement of the container body with respect to the stand is formed.

In the discharge container according to the present invention, the container body can be tilted together with the stand even when the container body is still fitted in the stand. In other words, since the engaging portion formed on the body portion of the container body is engaged with the finger pad portion formed on the peripheral wall portion of the stand, the container body can be removed from the stand even if the stand is gripped and tilted. It is hard to come off. Therefore, the contents can be easily discharged.
In addition, when the stand is gripped, it can be gripped while applying the fingertip to the finger rest, so that the fingertip is difficult to slip and the stand and the container body are easily tilted. In this respect as well, it is easy to perform the content discharge operation.

(6) In the discharge container according to the present invention, in the discharge container according to the present invention, a portion of the top wall portion that defines the discharge port is provided with a cut piece via a breakable weakening portion. The discharge port is provided so as to project outward in the radial direction, and the film extends so as to cover the upper surface of the cut piece, and an outer peripheral edge thereof is sealed on the cut piece along a circumferential direction. It is characterized by sealing.

In the discharge container according to the present invention, the discharge port can be unsealed by separating (separating) the cut piece from the top wall portion via the weakened portion (thin wall portion). Therefore, thereafter, the contents can be discharged from the discharge port by tilting the container body.
On the other hand, at the stage of distribution or sales display, the cut piece is connected to the portion of the top wall that defines the discharge port, and the discharge port is sealed. Therefore, even if the container body is tilted, the contents are not discharged. Therefore, the leakage of the contents can be surely prevented at the stage before use.

(7) The discharge container according to the present invention is characterized in that, in the discharge container of the present invention, the top wall portion is inclined so that the discharge port is positioned above the outflow opening. To do.

  In the discharge container according to the present invention, when the container body is returned to its original state after the discharge of the contents, the contents remaining in the discharge passage naturally flow out using the inclination of the top wall portion. It returns to the side and easily flows into the container body through this outflow opening. Accordingly, the contents are less likely to remain in the discharge path, and the deformed film is likely to return to a state where the film is securely adhered to the top wall portion. Therefore, the sealing property of the container body can be enhanced.

(8) The discharge container according to the present invention is characterized in that, in the discharge container of the present invention, the top wall portion is formed in a concave curved surface shape, and the outflow opening is formed in the deepest portion of the top wall portion. And

  In the discharge container according to the present invention, after the contents are discharged, when the container body is returned to the original state, the contents remaining in the discharge path are curved in the shape of a concave curve. Then, it naturally returns to the outflow opening side and easily flows into the container body through the outflow opening. Accordingly, the contents are less likely to remain in the discharge path, and the deformed film is likely to return to a state where the film is securely adhered to the top wall portion. Therefore, the sealing property of the container body can be enhanced.

  According to the discharge container of the present invention, the contents can be easily discharged without performing a special operation, and it is easy to use. In addition, even a small amount of contents can be discharged smoothly, and the contents are easy to use without leaving waste.

  Hereinafter, embodiments of a discharge container according to the present invention will be described with reference to FIGS. 1 to 12. As shown in FIGS. 1 and 2, the discharge container 1 of the present embodiment is mounted on a container body 2 in which a liquid content W (see FIG. 5) is accommodated, and an opening 2 e of the container body 2. A discharge cap 3.

  FIG. 1 is an overall side view (partially sectional view) of the discharge container 1. FIG. 2 is a cross-sectional view taken along the line AA shown in FIG. Moreover, in this embodiment, let the direction orthogonal to the container axis O of the container body 2 be a radial direction, and let the direction which circulates around the container axis O be the circumferential direction. A direction from the container body 2 toward the discharge cap 3 along the container axis O is an upper side, and a direction toward the bottom 2a side of the container body 2 is a lower side.

The container body 2 of the present embodiment is a delamination bottle (laminated peelable container) in which the inner layer 4b is detachably laminated with respect to the outer layer 4a. 2d and the mouth part 2e are connected.
The bottom 2a is formed flat, and the container body 2 can be stably placed on the floor surface. The trunk | drum 2b is formed in the cross-sectional view ellipse shape. The shoulder portion 2c is a portion connected to the upper portion of the body portion 2b, and is formed so as to gradually decrease in diameter upward. The neck portion 2d is a portion that is connected to the upper portion of the shoulder portion 2c, and is formed in a circular shape in a cross-sectional view. In particular, the neck portion 2d is formed with an annular bulging portion (pressing deformation portion) 5 having a circular arc shape that bulges outward in the radial direction over the entire circumference of the neck portion 2d.

  The bulging portion 5 is configured to be deformed so as to be recessed inward when pressed with a fingertip. When the bulging portion 5 is depressed, the portion (inner layer 4b) located in the neck portion 2d is subjected to volume reduction deformation, and this container ( It plays a role of increasing the internal pressure of the inner layer 4b). The mouth portion 2e is a portion continuously provided on the upper portion of the neck portion 2d, and an annular engagement protrusion 2f is formed on the outer peripheral surface.

  As shown in FIG. 3, the discharge cap 3 is disposed along an outer cylinder portion 10 that surrounds the mouth portion 2 e of the container body 2 from the outside in the radial direction, and an inner peripheral surface of the mouth portion 2 e. The inner cylinder part 11 to be fitted in, the upper end of the outer cylinder part 10 and the upper end of the inner cylinder part 11, and a flange part 12 in contact with the opening end of the mouth part 2e, and upward from the flange part 12 The projecting cylindrical portion 13 provided in a protruding manner and the top wall portion 14 connected to the upper end portion of the projecting cylindrical portion 13 are formed in a cylindrical shape around the container axis O. FIG. 3 is an enlarged cross-sectional view around the discharge cap 3 of the discharge container 1 shown in FIG.

On the inner peripheral surface of the outer cylinder part 10, an annular claw part 10a that engages with the lower side of the engaging projection 2f on the mouth part 2e side is formed. Thereby, the discharge cap 3 is attached to the mouth portion 2e of the container body 2 by undercut fitting. The claw portions 10a may not be annular, and a plurality of claw portions 10a may be formed at intervals in the circumferential direction.
The inner side of the inner cylinder part 11 and the protruding cylinder part 13 functions as a communication path R1 that communicates with the inside of the container body 2 when the discharge cap 3 is attached.

The top wall portion 14 is formed with an outflow opening 15 that communicates with the communication path R1. Thereby, by tilting the container body 2, the contents W can flow out from the outflow opening 15 onto the top wall portion 14 through the communication path R <b> 1.
By the way, the ceiling wall part 14 of this embodiment is formed in the concave curved surface shape, and is formed so that it may incline with respect to the container axis | shaft O. FIG. Specifically, first, as shown in FIGS. 2 and 3, the top wall portion 14 is formed so as to close the upper end of the protruding cylindrical portion 13, and along the major axis of the elliptical body portion 2 b. It is formed in a vertically long rectangular shape. Moreover, one side of the top wall portion 14 is formed so as to protrude radially outward along the long axis. Hereinafter, the projecting side is referred to as the distal end portion 14a of the top wall portion 14, and the side opposite to the distal end portion 14a across the container shaft O is referred to as the proximal end portion 14b.

  The distal end portion 14a of the top wall portion 14 is inclined so as to be positioned above the proximal end portion 14b. Further, the top wall 14 is recessed so as to gradually become deeper from the outside toward the inside along the inclination direction L1 connecting the distal end portion 14a and the base end portion 14b and the orthogonal direction L2 orthogonal to the container axis O. It is formed in a curved surface shape. The outflow opening 15 is formed so as to be located at the deepest portion of the top wall portion 14.

Further, as shown in FIGS. 1 to 3, a cut piece 20 is connected to the discharge cap 3 of the present embodiment via a weakening portion 21 that can be broken with respect to the top wall portion 14.
Specifically, the cut piece 20 is provided so as to project radially outward from a distal end portion 14a which is a portion defining a discharge port 24 described later in the top wall portion 14 through the weakening portion 21. It is connected. The weakened portion 21 is a thin portion with a notch formed in the lower side, and the cut piece 20 is operated to twist or pull the cut piece 20 upward or downward as shown in FIG. As shown, it can be easily broken.
FIG. 4 is a view showing a state where the cut piece 20 is removed from the state shown in FIG.

  Moreover, a knob (see FIG. 2) 20a is connected to the cut piece 20. Therefore, it is possible to efficiently transmit the force to the cut piece 20 by using this knob 20a, so that the weakened portion 21 can be smoothly broken and the cut piece 20 can be separated from the top wall portion 14. It has become.

As shown in FIGS. 1 to 3, a film (sheet) 22 is overlaid on the ceiling wall portion 14 thus configured so as to cover the outflow opening 15. The film 22 is a film formed from a material that is hard to tear and has elasticity, and covers the entire top wall portion 14. Moreover, the film 22 extends to the cut piece 20 side as well as the top wall portion 14 and is sized to cover the entire top surface of the cut piece 20 before separation.
In addition, as the said film 22, although a general film (it does not have a stretching property) which is hard to tear can also be used, it is preferable to use the film which has a stretching property.

By the way, in the stage before separating the cut piece 20 from the top wall portion 14, the outer peripheral edge portion of the film 22 positioned radially outside the outflow opening 15 extends along the circumferential direction in the top wall portion 14 and the cut piece 20. Are respectively sealed (fixed) to the upper surface (hatching region S shown in FIG. 2). As a sealing method at this time, various methods such as an adhesive and heat welding (fusion, pressure bonding, etc.) may be adopted.
The film 22 separates the cut piece 20 from the top wall portion 14 and breaks. When attention is paid to the top wall part 14 after separation, as shown in FIG. 2, a part of the outer peripheral edge part of the film 22 is a non-seal part 23 in which the seal is partially released. The non-seal portion 23 is formed at a broken portion of the film 22.

In this embodiment, the non-seal part 23 is formed in the front-end | tip part 14a of the top wall part 14. As shown in FIG. The non-seal portion 23 and the top wall portion 14 define a discharge port 24 through which the content W that has flowed out from the outflow opening 15 is discharged.
That is, in this embodiment, before the cut piece 20 is separated from the top wall portion 14, as shown in FIG. 2, the film 22 whose outer peripheral edge portion is sealed along the circumferential direction on the cut piece 20. The discharge port 24 is sealed. Then, by separating the cut piece 20 from the top wall portion 14, the film 22 sealed on the cut piece 20 is broken along with the separation, and the discharge port 24 is formed on the top wall portion 14 as shown in FIG. 4. It appears at the tip 14a.
Further, as described above, the top wall portion 14 is inclined so that the distal end portion 14a is located above the base end portion 14b, and therefore the discharge port 24 is located above the outflow opening 15. It is supposed to be.

Next, the case where the contents W are discharged using the discharge container 1 configured as described above will be described.
First, at the stage of distribution or sales display, as shown in FIGS. 1 to 3, a cut piece 20 is connected to the tip end portion 14 a of the top wall portion 14 via a weakening portion 21. Therefore, the discharge port 24 is sealed by the cut piece 20. Therefore, in use, the cut piece 20 is first removed from the top wall portion 14. That is, as shown in FIG. 4, the weakened portion 21 is broken by pulling the knob portion 20 a, and the cut piece 20 is separated from the top wall portion 14. As a result, the discharge port 24 can be unsealed.

Thereafter, as shown in FIG. 5, the container body 2 is tilted so that the front end portion 14 a of the top wall portion 14 is on the lower side. Then, the content W accommodated in the container body 2 flows into the outflow opening 15 through the communication path R1, and flows out while pushing up the film 22 onto the top wall portion 14 from the outflow opening 15. Then, the film 22 is pressed in a direction away from the top wall portion 14 by the dead weight of the content W that has flowed out, reversely deforms, and swells in a dome shape protruding upward. Thereby, a gap between the top wall portion 14 and the film 22 becomes a discharge path R <b> 2 connected to the discharge port 24.
Therefore, the contents W flowing out from the outflow opening 15 can be guided to the discharge port 24 through the discharge path R2, and discharged from the discharge port 24 to the outside.

  When the container body 2 is returned to a posture where the weight of the contents W is not applied to the film 22 after the discharge is finished, the pressing force applied to the film 22 is released, and the film 22 that has been deformed into a dome shape is released. It returns to its original state by reverse deformation and is in close contact with the top wall 14. Therefore, as shown in FIG. 4, the outflow opening 15 is closed again by the film 22 and the discharge port 24 is closed. Thereby, sealing of the container body 2 is securable.

As described above, according to the discharge container 1 of the present embodiment, the container body 2 is tilted, and discharge can be performed by a simple method of reversing and deforming the film 22 by the weight of the contents W, so that a special operation is performed. The discharge operation can be easily performed without any problems and is easy to use.
By the way, when the contents W are discharged, the inner layer 4b of the container body 2 starts to be reduced and deformed so that the inner layer 4b gradually peels off from the outer layer 4a. The outer layer 4a is formed with air holes (not shown) that communicate the inside and outside of the outer layer 4a (for example, in the mouth 2e, the neck 2d, or the bottom 2a), whereby the inner layer 4b is accompanied by the discharge of the contents W. To reduce volume.

  Moreover, even when the remaining amount of the contents W is reduced, the remaining contents W can be discharged smoothly, and the contents W can be used up without being wasted. That is, when the remaining amount of the contents W decreases, the bulging portion 5 formed on the neck portion 2d of the container body 2 is pressed with a fingertip or the like as shown in FIG. Press and deform.

Thereby, the volume of the container (inner layer 4b) located in the neck 2d can be reduced and deformed to increase the internal pressure of the container (inner layer 4b). Then, this increased internal pressure acts to push the film 22 upward in order to escape to the outside through the discharge port 24. Therefore, the force with which a small amount of contents W try to push up the film 22 by its own weight can be assisted, and the discharge path R <b> 2 connecting the outflow opening 15 and the discharge port 24 can be defined.
As a result, even a small amount of contents W can be discharged smoothly, and the contents W can be used up easily without leaving them.

Furthermore, according to the discharge container 1 of this embodiment, there can exist the following effects.
That is, at the stage of distribution or sales display, the cut piece 20 is connected to the top wall 14 and the discharge port 24 is sealed, so that the contents W can be obtained even if the container body 2 is tilted. Is not discharged. Therefore, the leakage of the contents W can be reliably prevented at the stage before use.
Further, when the cut piece 20 is separated from the top wall portion 14, the force can be efficiently transmitted to the cut piece 20 using the knob 20a, so that the weakened portion 21 can be smoothly broken. Therefore, it becomes easy to separate the cut piece 20 along the weakened portion 21.

Furthermore, the top wall portion 14 of the present embodiment is inclined so that the distal end portion 14a is located above the base end portion 14b and the discharge port 24 is located above the outflow opening 15. Therefore, when the container body 2 is returned to the original state after the discharge of the contents W, the contents W remaining in the discharge passage R2 naturally use the inclination of the top wall portion 14 to the outflow opening 15 side. The flow easily returns to the inside of the container body 2 through the outflow opening 15.
Moreover, the top wall portion 14 is not only inclined but also formed in a concave curved surface shape, and an outflow opening 15 is formed in the deepest portion. Therefore, also at this point, the content W remaining in the discharge passage R2 naturally returns to the outflow opening 15 side by using the curvature of the top wall portion 14, and easily flows into the container body 2 through the outflow opening 15. .

  As described above, the contents W naturally easily return to the outflow opening 15 side, so that the contents W hardly remain in the discharge path R2. Therefore, the film 22 that has been inverted and deformed so as to swell in a dome shape is likely to return to a state in which the film 22 is securely adhered to the top wall portion 14. Therefore, the sealing property of the container body 2 can be improved.

  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, when the discharge cap 3 is attached to the mouth portion 2e, the discharge cap 3 may be attached by screwing rather than undercut fitting. In this case, it is preferable to provide a mechanism for positioning the discharge cap 3 in the circumferential direction with respect to the mouth portion 2e so that the discharge port 24 faces in a desired direction. As the mechanism, various generally known methods for restricting rotation in the circumferential direction may be employed.

  In the above embodiment, the top wall portion 14 of the discharge cap 3 is formed to be inclined when the container body 2 is erected. However, the ceiling body 14 extends along a horizontal plane perpendicular to the container axis O. The wall portion 14 may be formed. Moreover, in the said embodiment, although the top wall part 14 was formed so that it might become a concave curved surface shape, you may form so that it may become a flat flat surface.

In either case, the same effects can be achieved. In addition, when the top wall portion 14 is formed flat, a stretchable film is employed. However, when the concave wall shape is formed as in the above embodiment, the film 22 can be inverted and deformed. Therefore, a general film having no stretchability can also be adopted. By adopting the stretchable film 22, when the container body 2 is tilted, the film 22 can be elastically deformed so as to be separated from the top wall portion 14 by the weight of the contents W. Thus, the discharge path R2 can be reliably formed in a dome shape that bulges convexly.
In this way, the material of the film is appropriately changed according to the shape of the top wall portion 14, and various deformations such as reverse deformation and elastic deformation are caused by the weight of the contents W, so that the discharge path R <b> 2 connected to the discharge port 24 is formed. Just make sure it is defined.

Moreover, in the said embodiment, although it was set as the structure which connected the cutting piece 20 to the front-end | tip part 14a of the top wall part 14 via the weakening part 21, this cutting piece 20 is not essential and does not need to be provided.
Further, the bulging portion 5 is formed in an annular shape over the entire circumference of the neck portion 2d. However, the bulging portion 5 does not have to be in an annular shape, and one bulging portion 5 that bulges in a convex shape may be formed. A plurality may be formed while opening.

  Moreover, in the said embodiment, although the discharge cap 3 was comprised so that the inside of the container body 2 and the outflow opening 15 might always be connected, even if it comprises the discharge cap 3 so that a communication state and a interruption | blocking state may be switched suitably. I do not care. Hereinafter, the configuration in this case will be described.

As shown in FIG. 7, the discharge cap 30 in this case can be moved relative to the cap main body 40 attached to the mouth 2e of the container body 2 and the cap main body 40, specifically, can move up and down. The discharge head 50 to be mounted is configured in a top cylinder shape.
FIG. 7 is a cross-sectional view of the discharge cap 30 attached to the mouth portion 2e of the container body 2, and shows a state before and after the upward movement. However, the cut piece 20 shows the state already removed.

  The cap body 40 includes an outer cylinder portion 41 that surrounds the mouth portion 2e of the container body 2 from the radially outer side, and an inner cylinder portion that is disposed along the inner peripheral surface of the mouth portion 2e and is fitted into the mouth portion 2e. 42, the upper end of the outer cylinder part 41 and the upper end of the inner cylinder part 42 are connected in series, and a top wall part 43 that closes the opening end of the mouth part 2e, and is projected upward from the top wall part 43 The guide tube 44 is configured by a guide tube 44 and a cap 45 having a top tube shape disposed radially inward of the guide tube 44 and projecting upward from the top wall portion 43.

On the inner peripheral surface of the outer cylinder portion 41, an annular claw portion 41a that engages with the lower side of the engaging projection 2f on the mouth portion 2e side is formed. Thereby, the cap main body 40 is attached to the mouth portion 2e of the container body 2 by undercut fitting. The claw portions 41a may not be annular, and a plurality of claw portions 41a may be formed at intervals in the circumferential direction.
The guide tube 44 is a tube that guides the vertical movement of the discharge head 50, and the opening end is obliquely cut in accordance with the inclination of the top wall portion 14. In a part of the inner peripheral surface of the guide cylinder 44, a vertically long guide groove 44a extending along the container axis O is formed downward from the open end.

The inside of the plug body 45 communicates with the inner cylinder portion 42 through an opening 43 a formed in the top wall portion 43. The inner cylindrical portion 42 and the inside of the plug body 45 function as a first communication path R3 that communicates with the inside of the container body 2 when the cap body 40 is attached.
By the way, a slit-like notch 45a is formed along a container axis O in a part of the peripheral surface of the plug body 45, and the inside and the outside of the plug body 45 are communicated with each other. Further, the top wall portion 43 is formed with a notch hole 43b so as to communicate with the notch groove 45a. Therefore, the first communication path R3 is open through the notch groove 45a and the notch hole 43b.

The discharge head 50 includes an outer slide cylinder 51 that surrounds the guide cylinder 44 of the cap body 40 from the radially outer side, an inner slide cylinder 52 that surrounds the guide cylinder 44 from the radially inner side, and the outer slide cylinder 51 and the inner slide cylinder 52. And a ceiling wall portion 14 provided at the upper end.
The discharge head 50 is combined with the cap body 40 such that the guide cylinder 44 of the cap body 40 is fitted between the outer slide cylinder 51 and the inner slide cylinder 52, and the guide cylinder 44 guides the discharge head 50. It is possible to move up and down. At this time, on the outer peripheral surface of the inner slide cylinder 52, vertical ribs 52a are formed that fit in guide grooves 44a formed on the cap body 40 side so as to be movable up and down.
Thereby, the discharge head 50 is combined with the cap body 40 in a state where rotation in the circumferential direction is restricted, and moves up and down without rotating.

  By the way, the outflow opening 15 formed in the top wall portion 14 communicates with the inner slide cylinder 52. Therefore, the inside of the inner slide cylinder 52 functions as a second communication path R <b> 4 that communicates with the outflow opening 15. At this time, as described above, since the first communication path R3 is opened through the notch groove 45a and the notch hole 43b, the first communication path R3 and the second communication path R4 are always in communication with each other.

  In addition, the inner slide cylinder 52 is formed with a partition wall 53 in which a fitting hole 53a into which the plug body 45 of the cap body 40 is detachably fitted is formed. In the partition wall 53, when the discharge head 50 moves downward and the lower end portion of the outer slide cylinder 51 is in contact with the top wall portion 43 of the cap body 40, the plug body 45 is inserted into the insertion hole 53 a, and the discharge head 50. When the lower end of the outer slide cylinder 51 moves away from the top wall 43 of the cap body 40, the plug 45 is formed so as to be detached from the insertion hole 53a.

That is, when the ejection head 50 is moved downward, the insertion hole 53a is blocked by the plug body 45, and when the ejection head 50 is moved upward, the plug body 45 is detached from the insertion hole 53a. Yes. In other words, when the discharge head 50 is moved downward, the second communication path R4 is interrupted by the plug 45, and when the discharge head 50 is moved upward, the block by the plug 45 is released.
That is, the inside of the container body 2 and the outflow opening 15 are switched to a communication state or a blocking state with each other through the first communication path R3 and the second communication path R4 as the ejection head 50 moves up and down.

  An annular claw portion 51a is formed on the inner peripheral surface of the outer slide cylinder 51 so as to protrude inward. On the other hand, on the outer peripheral surface of the guide tube 44 of the cap body 40, annular grooves 44b into which the claw portions 51a are respectively fitted when the discharge head 50 is moved downward or moved upward are formed. Thereby, when the ejection head 50 is moved upward or downward, the ejection head 50 can be positioned at that position.

The case where the contents W are discharged using the discharge cap 30 configured as described above will be briefly described.
In this case, the ejection head 50 is moved upward with respect to the cap body 40. Then, along with this movement, the upper part of the plug body 45 of the cap body 40 comes out of the insertion hole 53a and is detached. Thereby, since interruption | blocking of 2nd communicating path R4 is cancelled | released, the inside of the container body 2 and the outflow opening 15 will be in the state mutually connected through 1st communicating path R3 and 2nd communicating path R4. Therefore, thereafter, the contents W can be discharged by tilting the container body 2.

  When the ejection head 50 is moved upward, the claw portion 51a is fitted into the annular groove 44b, so that the ejection head 50 is positioned at this position. Therefore, there is little possibility that the ejection head 50 moves downward during the ejection of the contents W and the communication between the inside of the container body 2 and the outflow opening 15 is unexpectedly blocked.

  And when discharge of the content W is complete | finished and performing storage, the discharge head 50 is moved below with respect to the cap main body 40, and is returned to the original state. Then, since the upper part of the plug body 45 is fitted again into the fitting hole 53a, the second communication path R4 is blocked on the way. Therefore, the inside of the container body 2 and the outflow opening 15 that have been communicated with each other can be blocked. Therefore, even if the container body 2 is tilted by mistake during storage or the like, the contents W can be prevented from flowing into the outflow opening 15.

  Similarly, when the ejection head 50 is moved downward, the claw portion 51a is fitted into the annular groove 44b, so that the ejection head 50 is positioned at this position. Therefore, there is little possibility that the discharge head 50 moves upward during storage and the inside of the container body 2 and the outflow opening 15 communicate unexpectedly.

  By configuring the discharge cap 30 as described above, the distribution route to the outflow opening 15 can be communicated or blocked depending on the situation, and the contents W are unlikely to be discharged when not intended.

  In FIG. 7, the discharge head 50 is moved up and down with respect to the cap main body 40, so that the inside of the container body 2 and the outflow opening 15 are switched so as to communicate with each other or shut off. However, it is only necessary that the ejection head 50 is switched by moving the ejection head 50 relative to the cap body 40.

For example, as shown in FIG. 8, a cap main body 70 attached to the mouth 2e of the container body 2 and a discharge head 80 attached to the cap main body 70 so as to be movable relative to the cap main body 70, specifically to be rotatable. The discharge cap 60 may be configured as described above.
FIG. 8 is a cross-sectional view of the discharge cap 60 attached to the mouth 2e of the container body 2 and shows a state before and after rotation. However, the cut piece 20 shows the state already removed.

  The cap body 70 includes an outer cylinder 71 that surrounds the mouth 2e of the container body 2 from the outside in the radial direction, and an inner cylinder that is disposed along the inner peripheral surface of the mouth 2e and is fitted into the mouth 2e. 72, the upper end of the outer cylinder part 71 and the upper end of the inner cylinder part 72 are connected in series, and a top wall part 73 that closes the opening end of the mouth part 2e, and is projected upward from the top wall part 73 The outer guide cylinder 74 and an inner guide cylinder 75 disposed radially inward of the outer guide cylinder 74 and projecting upward from the top wall portion 73 are configured.

On the inner peripheral surface of the outer cylindrical portion 71, an annular claw portion 71a that engages with the lower side of the engaging projection 2f on the mouth portion 2e side is formed. Thereby, the cap main body 70 is attached to the mouth portion 2e of the container body 2 by undercut fitting. The claw portions 71a may not be annular, and a plurality of claw portions 71a may be formed at intervals in the circumferential direction.
The inner side of the inner cylinder part 72 functions as a first communication path R3 that communicates with the inside of the container body 2 when the cap body 70 is attached.

  The outer guide cylinder 74 is a cylinder that guides the rotation of the ejection head 80. On the outer peripheral surface of the outer guide cylinder 74, an annular claw portion 74a protruding outward is formed, and a pair of vertical ribs 74b are formed so as to face each other with the container shaft O interposed therebetween. The pair of vertical ribs 74b is formed in the vicinity of the upper end portion of the outer guide cylinder 74, and is a regulating member for positioning each of the ejection heads 80 about the container axis O at a half-rotation position.

  Similarly to the outer guide cylinder 74, the inner guide cylinder 75 is a cylinder that guides the rotation of the discharge head 80, and is formed to be lower in height than the outer guide cylinder 74. A slit-like cutout groove 75 a is formed along a container axis O in a part of the inner guide cylinder 75. Further, a cutout hole 73a is formed in the top wall portion 73 so as to communicate with the cutout groove 75a. Therefore, the first communication path R3 is open through the notch groove 75a and the notch hole 73a.

  The discharge head 80 is formed in a stepped shape surrounding the outer guide cylinder 74 of the cap body 70 from the radially outer side, and a part of the outer guide cylinder 74 and the inner guide cylinder 75 from the radially inner side. The inner rotary cylinder 82, and the outer wall 81 and the top wall 14 connected to the upper ends of the inner rotary cylinder 82 are provided.

  The discharge head 80 is combined with the cap body 70 so that the outer guide cylinder 74 and the inner guide cylinder 75 of the cap body 70 are fitted between the outer rotating cylinder 81 and the inner rotating cylinder 82, respectively. The container can be rotated about the container axis O while being guided by the outer guide cylinder 74 and the inner guide cylinder 75.

  An annular protrusion 81a that engages with an annular claw 74a formed on the cap main body 70 side is formed on the inner peripheral surface of the outer rotating cylinder 81 to prevent the ejection head 80 from coming off. . Also, a part of the inner peripheral surface of the outer rotating cylinder 81 is formed with a contact rib 81b that contacts a vertical rib 74b formed on the cap body 70 side. The abutment rib 81b abuts on the vertical rib 74b every time the ejection head 80 is rotated halfway around the container axis O. Thereby, the rotation of the discharge head 80 can be restricted to 180 degrees, and the direction of the discharge port 24 can be positioned in two directions.

By the way, the outflow opening 15 formed in the top wall portion 14 communicates with the inner rotary cylinder 82. Therefore, the inner side of the inner rotary cylinder 82 functions as a second communication path R <b> 4 that communicates with the outflow opening 15. The inner rotating cylinder 82 is in contact with the inner guide cylinder 75 of the cap main body 70, and basically closes the notch groove 75a on the cap main body 70 side to block the first communication path R3.
However, a slit-like longitudinal groove 82 a is formed along a container axis O in a part of the inner rotary cylinder 82. The vertical groove 82a is a notch groove on the cap body 70 side when the contact rib 81b contacts the vertical rib 74b to restrict the rotational position of the discharge head 80 and the direction of the discharge port 24 is positioned in one direction. It communicates with 75a. Thereby, 1st communicating path R3 and 2nd communicating path R4 are mutually connected. That is, the inside of the container body 2 and the outflow opening 15 communicate with each other through the first communication path R3 and the second communication path R4.

On the other hand, when the discharge head 80 is rotated halfway around the container axis O from the above position and the direction of the discharge port 24 is positioned in the other direction, the inner rotary cylinder 82 closes the notch groove 75a on the cap body 70 side. It has become. Accordingly, the communication between the first communication path R3 and the second communication path R4 is blocked again.
That is, the inside of the container body 2 and the outflow opening 15 are switched to a communication state or a blocking state with each other through the first communication path R3 and the second communication path R4 as the discharge head 80 rotates.

The case where the contents W are discharged using the discharge cap 60 configured as described above will be briefly described.
In this case, the discharge head 80 is rotated relative to the cap body 70 around the container axis O. Then, the contact rib 81b contacts the vertical rib 74b when the discharge head 80 rotates halfway, and the direction of the discharge head 80 is positioned in one direction. At this time, the longitudinal groove 82a of the ejection head 80 and the cutout groove 75a of the cap body 70 are in communication with each other. Thereby, the inside of the container body 2 and the outflow opening 15 are in a state of communicating with each other through the first communication path R3 and the second communication path R4. Therefore, thereafter, the contents W can be discharged by tilting the container body 2.

  And when discharge of the content W is complete | finished and performing storage, the discharge head 80 is rotated halfway in the reverse direction. Then, since the contact rib 81b contacts the vertical rib 74b again, the direction of the discharge head 80 is positioned in the other direction. Further, since the inner rotary cylinder 82 of the discharge head 80 blocks the cutout groove 75a of the cap body 70, the communication between the first communication path R3 and the second communication path R4 is blocked. Therefore, the inside of the container body 2 and the outflow opening 15 that have been communicated with each other can be blocked. Therefore, even if the container body 2 is tilted by mistake during storage or the like, the contents W can be prevented from flowing into the outflow opening 15.

  As described above, even in the case of the discharge cap 60 including the discharge head 80 that rotates, the flow route to the outflow opening 15 can be communicated or blocked depending on the situation, so that the contents are not intended. It is difficult to discharge the object W.

Moreover, in the said embodiment, although it was set as the container body 2 in which the bottom part 2a was formed flat, as shown in FIG.9 and FIG.10, the trunk | drum 2b is formed in the cross-sectional view ellipse shape, and the bottom part 2a is formed. The container body 2 may be formed in a convex curved shape downward. FIG. 9 is a side view (partially sectional view) of the discharge container 90. 10 is a cross-sectional view taken along the line BB shown in FIG.
Further, the discharge container 90 in this case is provided with a stand 91 which is an outer case in which the container body 2 is detachably fitted along the container axis O and supports the container body 2 in an upright state.

The stand 91 is formed in an elliptical shape in cross section, and includes a peripheral wall 92 surrounding the container body 2 from the outside in the radial direction, a bottom wall 93 connected to the lower end of the peripheral wall 92, and a peripheral wall 92. The bottom wall 93 is formed in a bottomed cylindrical shape with a frame portion 94 that extends downward from a continuous portion with the bottom wall 93 and surrounds the periphery of the bottom wall 93.
The peripheral wall portion 92 is designed to have such a height that the upper portion of the body portion 2b of the container body 2 is exposed when the container body 2 is fitted. In addition, the peripheral wall 92 is formed with a large opening 92a for holding a portion of the body 2b of the container body 2 fitted in the stand 91 so as to face each other across the container axis O. .

In this way, the body 2b of the container body 2 is formed in an elliptical shape in a cross-sectional view, and the bottom 2a is formed in a convex curved surface, whereby a boundary portion between the body 2b and the bottom 2a of the container 2 (see FIG. 10 can be smoothly bent with a large curvature. That is, it is possible to prevent a bent portion having a small curvature from appearing at a boundary portion between the body portion 2 b and the bottom portion 2 a of the container body 2.
Therefore, as the contents W are discharged, the inner layer 4b of the container body 2 can be peeled off from the outer layer 4a with less resistance. Therefore, the inner layer 4b can be deformed and deformed more reliably.

  Further, when the container body 2 is stored or is temporarily placed during use, the container body 2 is fitted into the stand 91 along the container axis O. Thereby, even if it is the container body 2 in which the bottom part 2a is formed in the convex curve shape, it can support stably in an upright state. Therefore, it is difficult to cause a problem that the container body 2 falls and the contents W leak from the discharge port 24.

  Moreover, when discharging the contents W, it is possible to perform the discharging operation even when the container body 2 is still fitted in the stand 91. That is, the trunk portion 2 b of the container body 2 can be gripped through the opening 92 a formed in the peripheral wall portion 92 of the stand 91. Therefore, without removing the container body 2 from the stand 91, the container body 2 can be tilted together with the stand 91, and the discharge operation of the contents W can be easily performed.

  However, in the stand 91, the opening 92a is not essential and may not be provided. In this case, the container body 2 may be removed from the stand 91 every time the content W is discharged. However, by forming the opening 92a in the peripheral wall 92 as described above, the container body 2 can be stably tilted together with the stand 91, which is more preferable in that the discharge operation can be easily performed.

Further, the following configuration may be adopted instead of the opening 92a.
That is, as shown in FIGS. 11 and 12, a finger rest portion 92 b that is recessed inward may be formed in the peripheral wall portion 92 of the stand 91. FIG. 11 is a side view (partially sectional view) of the discharge container 90. FIG. 12 is a cross-sectional view taken along the line CC shown in FIG.

  The finger contact portion 92b is formed so as to extend in the circumferential direction on the upper side of the peripheral wall portion 92, and is formed so as to face each other with the container axis O interposed therebetween. The body 2b of the container body 2 is formed with an engagement portion 95 that engages with the finger contact portion 92b when fitted into the stand 91. The engaging portion 95 plays a role of regulating the movement of the container body 2 along the container axis O with respect to the stand 91.

  When configured in this way, the container body 2 can be tilted together with the stand 91 even when the container body 2 is still fitted in the stand 91. That is, since the engaging portion 95 formed on the body portion 2b of the container body 2 is engaged with the finger rest portion 92b formed on the peripheral wall portion 92 of the stand 91, the stand 91 is grasped and tilted. However, it is difficult for the container body 2 to fall out of the stand 91. Therefore, the discharge operation of the contents W can be easily performed similarly.

  In addition, when the stand 91 is gripped, it can be gripped while applying the fingertip to the finger rest 92b, so that the fingertip is difficult to slip and the stand 91 and the container body 2 are easily tilted. Therefore, the discharge operation of the contents W can be easily performed.
