[Assembly of container with discharge function]
Next, with reference to FIGS. 1, 2, 5, and 6, an assembly process of the container 1 with a discharge function will be described. FIG. 5 is a perspective view showing the inner box 11. FIG. 6 is a cross-sectional view (rear view) showing a state in which the contents M and the like are contained in the container 1 with a discharging function. The container 1 with the discharging function may be manually assembled by an operator, or may be automatically or semi-automatically assembled by a box making machine. Here, as an example, a case where an operator manually manufactures the container 1 with a discharging function will be described. Further, in the blank 5 of the outer box 10, the rear wall 21R and the right wall 20R are bent along the first folding curve L1, and the passage piece 22 is adhered to the back surface of the right wall 20R with an adhesive. To do. That is, the outer box 10 is in a folded state.

<Inner box assembly>
First, a process of assembling the inner box 11 will be described. The worker turns the back surface of the blank 6 (see FIG. 4) upward and bends (raises) the first outer wall 70 at a substantially right angle along the eleventh folding curve L11 (two rising lines). The first frame portion 72 and the first inner wall 73 are folded back inward along L13 (see FIG. 5). In this state, the end wall portion 61 has a double wall structure in which the first outer wall 70 and the first inner wall 73 are opposed to each other with a gap therebetween. Then, a pair of end wall portions 61 are erected on the left and right ends of the bottom wall 60. Further, in this state, the outer wall piece 71 and the inner wall piece 74 also face each other with a gap therebetween.

Subsequently, the worker bends the outer wall piece 71 and the inner wall piece 74 (see FIG. 4) along the twelfth fold curve L12 and the fourteenth fold curve L14 at substantially right angles. In this state, the outer wall piece 71 and the inner wall piece 74 extend along both front and rear ends of the bottom wall 60. In addition, since the inner wall piece 74 is bent, the first convex portion 74A is hollowed out from the first inner wall 73 and enters the gap between the first outer wall 70 and the first inner wall 73. In addition, the first concave portion 74B is opened in the first inner wall 73 at a position where the first convex portion 74A is hollowed out (see FIG. 5).

Next, the worker folds (raises) the second outer wall 76 at a substantially right angle along the fifteenth fold line L15, and raises the second outer wall 76 along the two sixteenth fold line L16 by the second frame portion 77 and the second inner wall 78. Are folded inward (see Fig. 5). In this state, the side wall portion 62 has a double wall structure in which the second outer wall 76 and the second inner wall 78 are opposed to each other with the outer wall piece 71 and the inner wall piece 74 interposed therebetween. That is, the outer wall piece 71 and the inner wall piece 74 are wrapped in the side wall portion 62 that is a double wall. Then, a pair of side wall portions 62 are erected on both front and rear ends of the bottom wall 60. Further, in this state, the second inner wall 78 is press-fitted between the pair of end wall portions 61 (first inner wall 73) to prevent the double-walled end wall portion 61 from returning to the original state. .. Further, the pair of second convex portions 72A of the second inner wall 78 are fitted into the pair of first concave portions 74B opened in the pair of first inner walls 73 (see FIG. 5 ).

As described above, the tray-shaped (cell-shaped) inner box 11 having the upper surface opened is completed (see FIG. 5 ). The inner box 11 is longer in the left-right direction than in the front-rear direction.

<Assembling the outer box>
Next, a process of assembling the outer box 10 will be described. The worker bends the side wall 20 and the face wall 21 along the first folding curve L1, and raises the outer box 10 that is folded so that the side wall 20 and the face wall 21 form a substantially right angle. In this state, the right wall 20R and the left wall 20L face each other in the left-right direction, and the front wall 21F and the rear wall 21R face each other in the front-rear direction. Then, a substantially rectangular tubular peripheral wall 10W having upper and lower end surfaces opened is formed (see FIG. 2). The peripheral wall 10W is longer in the left-right direction than in the front-rear direction.

Subsequently, the worker folds the lower frame portion 32 and the winding wall 33 back inward along the two third folding curves L3, and the upper frame portion 30 and the regulation inner wall 31 into the two second folding curves L2. Fold inward along (see Figure 6). As a result, a pair of movement restricting portions 23 are formed inside the opening 10A (see FIGS. 2 and 6). As shown in FIG. 6, the movement restricting portion 23 is formed so as to be wound inward from the edge of the upper opening 10A. Further, the winding wall 33 (a part of the movement restricting portion 23) is overlapped with the inner surface of the side wall 20 (outer box 10). The movement restricting portion 23 has a double wall structure in which the restricting inner wall 31 and the winding wall 33 face each other. The leading end of the winding wall 33 is in contact with the inner surface of the upper frame portion 30.

Next, the operator folds the front frame portion 36 and the presser inner wall 37 inward along the two second folding curves L2 (see FIGS. 2 and 6). In this state, the presser inner wall 37 is arranged to face the front wall 21F with a gap therebetween (see FIG. 7 described later). Further, the presser inner wall 37 is press-fitted between the pair of movement restricting portions 23 (restriction inner wall 31) to prevent the movement restricting portion 23 from rewinding. Further, the pair of pressing projections 37A of the pressing inner wall 37 are fitted into the restriction recesses 31B formed in the pair of restriction inner walls 31 (not shown). Further, the restriction projections 31A formed on the pair of restriction inner walls 31 are fitted into the pair of press recesses 37B of the press inner wall 37 (not shown).

Next, the operator folds the pair of ceiling side walls 41 inward along the fourth folding curve L4 (see FIG. 2), and folds the pair of ceiling flaps 42 toward each other along the fifth folding curve L5. .. Further, the worker bends the top wall 43 inward along the fifth folding curve L5, folds the top frame portion 44 and the top inner wall 45 back along the two sixth folding curves L6, and inserts the reverse folding piece 46. Reverse folding is performed along the seventh folding line L7 (see FIGS. 2 and 7). As a result, the lid portion 25 is formed. In this state, the ceiling wall 43 and the ceiling wall 45 form a double-wall structure in which they face each other with the pair of ceiling flaps 42 interposed therebetween (see FIG. 7 ).

<Sealing of container with discharge function>
Here, with reference to FIGS. 6 and 7, a case where the container 1 with a discharging function is used as a container for packaging the contents M will be described. FIG. 7 is a sectional view taken along line VII-VII in FIG.

As shown in FIG. 6, the worker bends the lid 25 (top wall 40) along the second folding curve L2 and covers the opening 10A.

Next, the operator accommodates the plurality of contents M, the two rubber bands 12 and the one cord 13 inside the inner box 11, and then the inner box 11 with the opening surface facing upward is placed in the outer box 10 ( Insert it from the lower surface opening of the peripheral wall 10W). The rubber band 12 and the cord 13 may be housed in the outer box 10 (such as the lower side of the inner box 11) separately from the contents M.

Here, the outer dimension of the inner box 11 in the left-right direction is set smaller than the inner dimension of the outer box 10 (peripheral wall 10W) in the left-right direction, and the outer dimension of the inner box 11 in the front-rear direction is set to the outer box 10 (peripheral wall 10W). ) Is set smaller than the inner dimension in the front-back direction. Specifically, the outer dimensions (left, right, front and back) of the inner box 11 are set to be about 6 mm smaller than the inner dimensions (left, right, front and back) of the outer box 10. That is, a gap G of about 3 mm is formed between the inner surface of the outer box 10 and the outer surface of the inner box 11. Therefore, the inner box 11 is provided movably in the axial direction (vertical direction) inside the outer box 10 (peripheral wall 10W). The outer size of the inner box 11 is set smaller than the distance between the pair of movement restricting portions 23 (the inner dimension of the opening 10A in the left-right direction). The inner size of the inner box 11 is set to be substantially the same as the distance between the pair of movement restricting portions 23.

Next, the worker folds the pair of lower inner flaps 26 inward along the eighth folding curve L8. Further, as shown in FIG. 7, the worker folds the bottom wall 50 along the eighth folding curve L8 to close the lower surface opening of the peripheral wall 10W, and moves the insertion piece 51 inward along the ninth folding curve L9. Bend it and insert it inside the peripheral wall 10W. Further, the worker bends the locking connection portion 53 outward along the tenth fold curve L10, and also folds the locking piece 54 inward along the eighth fold curve L8 to form the bottom slit S2 of the insertion piece 51. Plug in. As a result, the bottom portion 27 can be locked in the closed state.

As described above, the lower surface opening of the peripheral wall 10W is closed, and the outer box 10 (container 1 with a discharging function) is sealed.

[Can be discharged form of container with discharging function]
Next, with reference to FIG. 7 and FIG. 8, a procedure for changing the container 1 with a discharging function from a packaging form of the contents M to a form in which the contents M can be discharged will be described. FIG. 8 is a sectional view taken along line VIII-VIII of FIG.

First, the user pulls out the locking piece 54 from the bottom surface slit S2, and then opens the bottom surface wall 50 while pulling out the insertion piece 51 from the peripheral wall 10W. Then, the user takes out the inner box 11, the rubber band 12 and the cord 13 from the lower surface opening of the peripheral wall 10W. The contents M may be taken out from the inner box 11 or may be left inside the inner box 11.

Subsequently, the user hooks the two rubber bands 12 on the pair of inner hooks 75 formed on the pair of first inner walls 73 of the inner box 11. Further, the user passes the cord 13 through the two ventilation holes 63 opened in the bottom wall 60 of the inner box 11, and then connects both ends of the cord 13 to form the cord 13.

Next, the user inserts the inner box 11 to which the rubber bands 12 and the cords 13 are attached into the inside from the lower surface opening of the peripheral wall 10W and slides it to the vicinity of the opening 10A of the outer box 10 (the peripheral wall 10W). As described above, since the inner size of the inner box 11 is substantially the same as the distance between the pair of movement restricting portions 23, the pair of first frame portions 72 of the inner box 11 are below the pair of movement restricting portions 23. It interferes with the frame portion 32. Therefore, the inner box 11 does not jump out of the opening 10A.

The user opens the lid 25 and puts his/her hand into the opening 10A, and hangs the pair of rubber bands 12 connected to the inner box 11 on the pair of outer hooks 35 formed on the pair of restricted inner walls 31 of the outer box 10. .. In this state, the pair of rubber bands 12 includes a pair of restriction inner walls 31 (a pair of inner walls of the outer box 10 facing each other) arranged near the opening 10A and a pair of first inner walls 73 (the inner box 11 of each other). The pair of inner walls facing each other). That is, the inner box 11 is suspended from the upper part of the outer box 10 via the pair of rubber bands 12. In this state, the rubber band 12 bites into the hooking portion 34A of the hooking cut line 34 (outer hook 35) and the constricted portion 75A of the inner hook 75.

Next, the user closes the bottom portion 27 again while passing the cord 13 extending downward from the inner box 11 through the operation hole 52 of the bottom wall 50. In this state, the cord 13 extends through the operation hole 52 formed in the bottom portion 27 of the outer case 10 to extend to the outside of the outer case 10.

As described above, the container 1 with the discharging function is in a form capable of discharging the contents M.

[Operation of container with discharge function]
Next, the operation of the container 1 with a discharging function will be described with reference to FIGS. 9 and 10. FIG. 9 is a sectional view (rear view) showing a state where the rubber band 12 is stretched. FIG. 10 is a cross-sectional view (rear view) showing a state in which the content M is released.

As briefly described above, the container 1 with a discharging function has a function of discharging the contents M contained therein to the outside. The user opens the lid 25 of the outer box 10 and places the contents M on the bottom wall 60 of the inner box 11 through the opening 10A. Subsequently, the user grasps the outer box 10 (peripheral wall 10W) with one hand and brings the opening 10A upward (obliquely upward). The outer box 10 may be in a horizontal posture with the opening 10A facing sideways, or may be in a posture with the opening 10A slightly facing downward so that the contents M do not drop.

Next, as shown in FIG. 9, the user grasps and pulls the cord 13 with the other hand, and pulls the pair of rubber bands 12 against the elastic force to stretch the inner box 11 away from the opening 10A in the separating direction. (See the arrow in FIG. 9). When the inner case 11 moves in the separating direction (axial direction), the air inside the outer case 10 has two air gaps G formed between the outer case 10 and the inner case 11 and the bottom wall 60 of the inner case 11. It passes through the hole 63 and the operation hole 52 formed in the bottom wall 50 of the outer case 10. As a result, an increase in air pressure inside the outer box 10 can be suppressed, and the inner box 11 can be smoothly moved in the separating direction.

As shown in FIG. 10, when the user releases his or her hand from the cord 13, the pair of rubber bands 12 try to return to their original lengths, and the release direction toward the opening 10A with respect to the inner box 11 (FIG. 10). (Refer to the arrow in), apply elastic force. The inner box 11 receives the elastic force of the pair of rubber bands 12 and vigorously moves in the discharge direction (axial direction). When the inner box 11 moves in the discharge direction (axial direction), air is passed through the gap G between the outer box 10 and the inner box 11 and the two ventilation holes 63 formed in the inner box 11. As a result, the inner box 11 can be smoothly moved in the discharging direction while suppressing the influence of air resistance.

Further, the inner box 11 that has moved vigorously in the discharging direction collides with the pair of movement restricting portions 23 of the outer box 10 and suddenly stops. Specifically, since the pair of first frame portions 72 of the inner box 11 interfere with the lower frame portions 32 of the pair of movement restricting portions 23, the inner box 11 is restricted from moving in the discharging direction. Then, the content M placed on the bottom wall 60 of the inner box 11 is subjected to an inertial force in the discharge direction, so that the content M jumps out of the inner box 11 vigorously. As a result, the contents M can be vigorously discharged from the opening 10A to the outside of the outer box 10.

In the container 1 with a discharging function according to the present embodiment described above, the inner box 11 moved in the separating direction against the elastic force of the pair of rubber bands 12 receives the elastic force of the pair of rubber bands 12 in the discharging direction. The contents M placed on the inner box 11 are discharged to the outside by being restricted in movement after being moved. Further, the inner box 11 is moved in the separating direction against the elastic force of the rubber band 12 to generate elastic force (elastic energy) in the rubber band 12. Since the elastic energy of the rubber band 12 increases as the stretching amount increases within the elastically deformable range, the user operates the cord 13 to increase or decrease the stretching amount of the rubber band 12, thereby acting on the inner box 11. The elastic force can be increased or decreased (adjusted). Thereby, the content M placed on the inner box 11 can be discharged to the outside while adjusting the elastic force acting on the inner box 11.

Moreover, in the container 1 with a discharge function according to the present embodiment, the pair of rubber bands 12 are arranged so as not to contact the inner surface of the outer box 10 or the outer surface of the inner box 11. If the rubber band 12 is arranged between the inner surface of the outer box 10 and the outer surface of the inner box 11, the rubber band 12 may be caught between the outer box 10 and the inner box 11. Then, the inner box 11 cannot slide smoothly inside the outer box 10. On the other hand, in the container 1 with a discharge function according to the present embodiment, the pair of rubber bands 12 are laid between the regulation inner wall 31 of the outer box 10 and the first inner wall 73 of the inner box 11, so that the outer box There is no possibility of being caught between 10 and the inner box 11. Accordingly, the inner box 11 can be smoothly slid inside the outer box 10. If the gap G between the outer case 10 and the inner case 11 is wide, the rubber band 12 may be arranged between the outer case 10 and the inner case 11 (not shown).

Further, according to the container 1 with a discharging function according to the present embodiment, by colliding the inner box 11 with the movement restricting portion 23, the inner box 11 moving in the discharging direction can be suddenly stopped. As a result, a large inertial force can be applied to the content M placed on the inner box 11, and the content M can be expelled to the outside.

Moreover, according to the container 1 with a discharge function according to the present embodiment, a part of the movement restricting portion 23 (the winding wall 33) overlaps the inner surface of the outer box 10, and the movement restricting portion 23 constitutes a double wall. (See FIG. 6, etc.). According to this configuration, the strength of the movement restricting portion 23 can be improved as compared with the case where the movement restricting portion 23 is a single wall. Further, the winding wall 33 of the movement restricting portion 23 was in contact with the upper frame portion 30 (see FIG. 6 and the like). According to this configuration, the impact when the inner box 11 collides can be reliably received, and the movement restricting portion 23 can be prevented from being damaged.

Further, according to the container 1 with a discharging function according to the present embodiment, since the two ventilation holes 63 are opened in the bottom wall 60 of the inner box 11, the air resistance when the inner box 11 is moved can be reduced. .. As a result, the inner box 11 can be vigorously and smoothly moved in the discharging direction, and proper discharge of the contents M placed on the inner box 11 can be ensured.

Moreover, according to the container 1 with a discharge function according to the present embodiment, an inexpensive cord 13 can be used as an example of the operation member. Further, the user can move the inner box 11 in the separating direction while stretching the rubber band 12 by an intuitive operation of grasping and pulling the cord 13 exposed to the outside of the outer box 10.

Further, according to the container with a discharge function 1 according to the present embodiment, by closing the opening 10A with the lid 25, the container with a discharge function 1 that has been once opened can be resealed.

[Modification of First Embodiment]
In addition, in the container 1 with a discharge function according to the first embodiment, two rubber bands 12 are adopted as an example of the elastic member, but the present invention is not limited to this. For example, as the container 1 with a discharging function according to the modified example of the first embodiment, as shown in FIG. 11, one rubber band 12 is installed between a pair of movement restricting portions 23, and the inner box 11 is bridged. The rubber band 12 may be placed on the rubber band 12. In this case, the rubber band 12 may be fixed to the bottom wall 60 of the inner box 11 or may not be fixed. Further, in FIG. 11, the rubber band 12 is passed between the outer case 10 and the inner case 11, but the invention is not limited to this, and the rubber band 12 may be passed through the inside of the end wall portion 61, or the bottom. Vent holes 63 in wall 60 may be passed through (not shown).

Besides, the outer box 10 and the inner box 11 may be connected via three or more rubber bands 12 (not shown). Further, the elastic member is not limited to the rubber band 12 and may be a string-shaped or thin plate-shaped rubber (not a ring-shaped rubber) (not shown). In this case, it is preferable that both ends of the rubber in the longitudinal direction are fixed to the outer box 10 and the inner box 11 with staples or adhesive tape. Further, for example, instead of the two rubber bands 12, two tension coil springs may be connected to the outer case 10 and the inner case 11 (not shown).

[Second Embodiment]
Next, with reference to FIG. 12, the container 2 with a discharging function according to the second embodiment will be described. FIG. 12 is a cross-sectional view (rear view) showing the container 2 with a discharging function. In the following description, configurations that are the same as or correspond to those of the container with a discharge function 1 according to the first embodiment are denoted by the same reference numerals, and descriptions of the same or corresponding to the container with a discharge function 1 are omitted.

In the container 2 with a discharging function, a compression coil spring 14 is used as another example of the elastic member. The compression coil spring 14 is arranged between the bottom wall 60 of the inner box 11 and the bottom wall 50 (lower inner flap 26) of the outer box 10 in a slightly compressed state. The upper end surface of the compression coil spring 14 may be fixed to the bottom wall 60 of the inner box 11, or may not be fixed. The cord 13 is arranged inside the compression coil spring 14. In this case, the outer hook 35 of the outer box 10, the inner hook 75 of the inner box 11 and the like may be omitted.

According to the container 2 with a discharging function according to the second embodiment described above, the compression coil spring 14 can apply an elastic force to the inner box 11 in the discharging direction. This makes it possible to obtain the same action and effect as the container 1 with a discharging function according to the first embodiment, such as being able to discharge the contents M placed on the inner box 11 to the outside.

[Modifications of First and Second Embodiments]
In addition, in the containers 1 and 2 with a discharging function according to the first and second embodiments (including modifications of the first embodiment, the same applies hereinafter), the cord 13 is formed in an annular shape. Is not limited to this. For example, the cord 13 may be fixed to the bottom wall 60 of the inner box 11 without extending in an annular shape and extended straight downward. Further, the cord 13 as an example of the operation member is a paper string, but the present invention is not limited to this. The cord 13 is not limited to a paper cord, but may be a cloth cord, a leather cord, or the like. As another example of the operating member, a rod-shaped operating member that does not flex flexibly may be connected to the bottom wall 60 of the inner box 11 (not shown).

[Third Embodiment]
Next, with reference to FIG. 13 and FIG. 14, a container 3 with a discharging function according to the third embodiment will be described. FIG. 13 is a sectional view (side view) showing the container 3 with the discharging function. FIG. 14 is a sectional view (rear view) showing the container 3 with the discharging function. In the following description, configurations that are the same as or correspond to those of the container with a discharge function 1 according to the first embodiment are denoted by the same reference numerals, and descriptions of the same or corresponding to the container with a discharge function 1 are omitted.

In the container 3 with a discharging function, the operating member 15 is formed in a rod shape that does not flex flexibly. The operation member 15 is fixed to the bottom wall 60 of the inner box 11 so as to extend in the left-right direction. A pair of side walls 20 of the outer box 10 are formed with guide grooves 10D extending in the vertical direction, and both left and right ends of the operating member 15 penetrate the guide grooves 10D and are exposed to the outside. A plurality of bent stopper portions 10S are formed in the guide groove 10D. In this case, the operation hole 52 in the bottom portion 27 of the outer box 10 may be omitted.

The user moves the inner box 11 in the separating direction while stretching the rubber band 12 by pulling the exposed portion of the operation member 15 in the separating direction. Then, the user hooks the operation member 15 on the arbitrary stopper portion 10S. As a result, the rubber band 12 can be held in a stretched state.

When the user removes the operating member 15 from the stopper portion 10S, the inner box 11 moves in the discharging direction by the elastic force of the rubber band 12. Thereby, the contents M placed in the inner box 11 can be discharged to the outside. In addition, the elastic force acting on the inner box 11 can be adjusted by changing the stopper portion 10S that hooks the operation member 15. The characteristics of the container 3 with the discharge function according to the third embodiment (the operation member 15 and the like) may be applied to the container 2 with the discharge function according to the second embodiment (not shown).

[Modifications of First to Third Embodiments]
In addition, in the containers 1 to 3 with a discharging function according to the first to third embodiments (including the modified example of the second embodiment, the same applies to the following), the inner box 11 contacts the pair of movement restricting portions 23. Thus, the movement of the inner box 11 in the discharge direction is restricted, but the present invention is not limited to this. The pair of movement restricting portions 23 may be omitted, and after the inner box 11 pops out of the opening 10A, elastic deformation of the elastic member such as the rubber band 12 naturally stops and the inner box 11 may be restricted in movement. With this configuration as well, the contents M placed on the inner box 11 can be discharged to the outside. In addition, when the pair of movement restricting portions 23 is omitted, the holding portion 24 may be omitted.

In addition, in the containers 1 to 3 with a discharging function according to the first to third embodiments, the movement restricting portion 23 has a double wall, but the present invention is not limited to this. For example, the lower frame portion 32 and the winding wall 33 may be omitted, and the regulation inner wall 31 may face the side wall 20 with a gap (not shown). Further, the upper frame portion 30 may be omitted, and the regulation inner wall 31 may be provided continuously to the side wall 20 (not shown).

In addition, in the containers 1 to 3 with the discharge function according to the first to third embodiments, the lid 25 is continuously provided to the outer box 10, but the present invention is not limited to this, and the lid 25 is different from the outer box 10. It may be configured as a body and detachably provided on the outer box 10 (not shown). The lid 25 may be omitted if the containers 1 to 3 with the discharging function do not have to be in the packaging form of the contents M.

Further, in the containers with discharge function 1 to 3 according to the first to third embodiments, the end wall portion 61 and the side wall portion 62 of the inner box 11 constitute a double wall, but the present invention is not limited to this. Not done. Either one of the end wall portion 61 and the side wall portion 62 may be a single wall (not shown). Further, although the inner box 11 is formed in a tray shape, it is not limited to this and may be formed in a plate shape. That is, the end wall portion 61 and the side wall portion 62 may be omitted, and only the bottom wall 60 may be used as the inner box (not shown).

Further, in the containers 1 to 3 with the discharging function according to the first to third embodiments, the outer size of the inner box 11 was about 6 mm smaller than the inner size of the outer box 10, but the present invention is not limited to this. The outer size of the inner box 11 is preferably set to be 4 to 20 mm smaller than the inner size of the outer box 10. That is, the gap G between the inner surface of the outer box 10 and the outer surface of the inner box 11 may be set within the range of 2 mm or more and 10 mm or less. By the way, generally, when nesting two boxes, the dimensional difference between the two boxes is often set to about 2 mm. That is, usually, the gap G between the two boxes is often set to about 0.5 to 1 mm. On the other hand, in the containers 1 to 3 with a discharging function according to the first to third embodiments, the gap G between the outer box 10 and the inner box 11 is set to be twice or more the normal value, so that the inner box 11 can be smoothly moved. I guarantee the slide.

In addition, in the containers 1 to 3 with the discharging function according to the first to third embodiments, the two vent holes 63 are opened in the bottom wall 60 of the inner box 11, but the present invention is not limited to this, and the vent holes 63 are 1 It is only necessary to open one or more. If the gap G between the outer case 10 and the inner case 11 is large, the ventilation hole 63 may be omitted (not shown). Further, the shape of the vent hole 63 is not limited to the substantially oblique shape (substantially square shape), and may be formed in a polygonal shape other than a circular shape or a quadrangle (not shown).

Moreover, although the outer boxes 10 of the containers 1 to 3 with a discharge function according to the first to third embodiments are formed in a rectangular tube shape that is long in the vertical direction, the dimensions (height, width, depth) of the outer box 10 are described. ) Can be changed arbitrarily. Also, the dimensions (height, width, depth) of the inner box 11 can be arbitrarily changed on condition that the inner box 11 slides in the outer box 10 in the axial direction.

Moreover, although the outer case 10 of the containers 1 to 3 with a discharge function according to the first to third embodiments is formed in a rectangular tube shape, the invention is not limited to this, and may be formed in a cylindrical shape, for example. It may be formed in a tubular shape having a polygonal cross section other than a quadrangle (not shown). Moreover, the inner box 11 may be formed in a cylindrical shape having a polygonal cross section other than a cylindrical shape or a quadrangle (not shown) in accordance with the shape of the outer box 10. Furthermore, the outer case 10 and the inner case 11 do not have to have similar shapes, and for example, the outer case 10 may be formed in a rectangular tube shape and the inner case 11 may be formed in a cylindrical shape (not shown). .. That is, the outer case 10 and the inner case 11 may be formed in different shapes, provided that the inner case 11 slides in the outer case 10 in the axial direction.

Further, the outer boxes 10 of the containers 1 to 3 with a discharging function according to the first to third embodiments are formed in a rectangular tube shape having the same thickness over the axial direction, but the present invention is not limited to this. .. For example, as shown in FIG. 15, the outer case 16 (peripheral wall 16W) may be formed in a truncated pyramid shape whose cross-sectional area gradually decreases from the lower part to the upper part. That is, the outer box 16 may be formed so that the inner box 11 (end wall portion 61) interferes with the upper part of the outer box 16 to regulate the movement in the discharge direction. In this case, the movement restriction unit 23 can be omitted. Alternatively, the outer box may be formed in a truncated cone shape or a truncated cone shape having a polygonal cross section other than a quadrangle (not shown). Further, the lower part of the outer box may be cylindrical with the same thickness, and the upper part of the outer box may be frustum-shaped (not shown). The outer box 16 may be applied to the containers with discharge function 2 and 3 according to the second and third embodiments.

Moreover, although the containers 1 to 3 with the discharge function according to the first to third embodiments are formed of paper corrugated cardboard sheets, the present invention is not limited to this, and is formed of cardboard, a resin plate (sheet), or the like. May be.

In addition, the description of the above embodiment shows one aspect of the container with a discharge function according to the present invention, and the technical scope of the present invention is not limited to the above embodiment.
