Description

  According to the present invention, it is possible to easily replace a package filled with a liquid or viscous liquid food, chemical, medicine, cosmetic or the like, and even when the container is firmly held, The present invention relates to a cassette type liquid material filling composite container capable of preventing accidental popping out of a package made of the liquid material.

  Heretofore, it is well known that a liquid material filling packaging container comprising a soft packaging bag and an outer container supporting the same is one in which an inner container (bag) and an outer container are integrated.

  For example, about the pouring nozzle which consists of a soft film, and a packaging bag provided with this, there are some which were disclosed by patent document 1 and patent document 2. FIG. In the packaging bag disclosed in these documents, the dispensing nozzle prevents the outside air from entering the packaging bag before and after pouring, as well as during pouring of the liquid packaged material in the packaging bag. It has a self-sealing function, and is configured to be able to easily pour out a liquid package by tilting the packaging bag from the tip of the dispensing nozzle.

  However, since all such packaging bags are made of a soft film, and the packaging body in which the liquid substance is filled in the packaging bag has neither self-supporting nor regularity, the packaging body is stored and held when used. A rigid outer container is required to provide self-sustaining, and is usually provided in an integral and non-separable manner in the outer container, ie as a fixed and combined product. As such an outer container, for example, the one shown in Patent Document 3 has been proposed.

Patent No. 4392198 Patent No. 4996815 gazette Patent No. 5669981 gazette

  The outer container of Patent Document 3 is configured to hold the non-self-supporting package stored therein at the upper end position of the package and to fix the package within the outer container. Therefore, when the remaining amount of the material to be packaged decreases and the angle of tilting the outer container at the time of dispensing the material to be packaged increases, the bottom of the package slips down toward the top of the outer container. In some cases, the packaged material is poured out in a large amount, and it becomes impossible to control the pouring amount of the packaged material.

  Moreover, the outer container of patent document 3 prevents the leakage of a package thing with respect to the unintended lodging etc. after opening of the tip of a pouring nozzle by sealing the pouring passage of a pouring nozzle by a clamping means. However, when the outer container is gripped without manual adjustment in a state in which the tightening means is removed, the package may fly out and contaminate the surroundings.

  Therefore, a first object of the present invention is to provide a cassette type liquid material filling composite container in which only the inner package (package bag + liquid material) can be easily replaced. Moreover, the second object of the present invention is that even if the user holds the outer container without manual intervention, accidental popping out of the packaged material can be sufficiently prevented, and the amount of the packaged material dispensed with a finger It is an object of the present invention to provide a cassette type liquid material filling composite container which can be discharged while being controlled to the end by pressing by the

In the research for achieving the above object, the inventor has conceived of the present invention according to the following configuration. That is, according to the present invention, a film-like dispensing nozzle made of a soft film is formed by filling a liquid or viscous package with a packaging bag provided on the side or top of a flexible packaging bag main body. The package body, and the intermediate cylinder whose upper end portion is substantially plate-like, and whose trunk portion is substantially flat with a hexagonal cross section through the mountain fold line, at least a part of the upper end portion of the package body inside the intermediate cylinder a cassette intermediate container made integrally locked with, be those covering the cassette intermediate container, to the cross-sectional shape of the body portion Na water droplets form or teardrop shape, a cylindrical outer container bottom portion is open consists, said cassette intermediate container, the outer by fitting and removal through the bottom opening of the container, removably cassette liquid product filling, characterized in that it is intended to be fitted in the outer container Abstract: A composite container is a gist configuration.

Also, the present invention is
(1) The intermediate cylinder has a pair of inward flange-like bottom plates that project in the diagonal direction at the lower end portion,
(2) The intermediate cylinder and the outer container are provided with a hooking piece provided in either the intermediate cylinder or the outer container, and a hooking hole provided in the other of the intermediate cylinder or the outer container. Being detachably fitted with the
(3) The outer container has a pair of holding claws on the upper end inner side for holding the upper end of the intermediate cylinder from both sides,
(4) A removable bottom frame is fitted to the lower end of the outer container.
(5) The outer container is provided with a plurality of slits extending laterally in the lower part of the body portion,
(6) The outer container is provided with a plurality of slits at predetermined intervals in the longitudinal direction on at least one side.
(7) The pouring nozzle is made of a soft layered film having a layered structure, and in a state where the layered film is superposed on the front and back, heat fusion is performed at the peripheral edge except for the base end portion and the central portion is poured out. It is sectioned and formed as a passage, and extends across the pouring passage to a position on the tip side within 4 mm from the planned opening position formed across the pouring passage, and the front and back A pressing portion for blocking the pouring passage by the close contact between the laminated films of the first and second layers, and the pressing portion is used for the liquid pressure of the liquid or viscous package to be introduced which flows from the packaging bag main body side. Accordingly, the seal valve is configured to open the pouring passage by separating the front and back laminated films from each other,
(8) The dispensing nozzle dispenses the liquid or viscous package within the packaging bag main body without tilting the packaging bag main body or pressing the packaging bag main body against suction of the outside air. At the same time, when stopping the pouring based on the return of standing up of the packaging bag main body or the release of the pressing on the packaging bag main body, the inner surface of the pouring passage of the pouring nozzle is Having a self-sealing function that prevents external air from invading the packaging bag body by immediately sealing under the presence of a thin film
It is considered to be a more preferable solution to adopt.

  A first feature of the present invention resides in that a cassette type liquid material filling composite container according to the above-described configuration is adopted. According to the composite container having such a configuration, since the cassette intermediate container is configured to be replaced, there is no need to handle the package having neither regularity nor self-sustaining ability as in the prior art, and the consumer himself The replacement operation can be performed centering, and the replacement operation can be easily performed only by fitting the cassette intermediate container into the outer container without the need for the alignment of the dispensing nozzle. That is, according to the present invention, it is possible to easily refill the package just by removing the cassette intermediate container from the outer container and replacing it with a new one.

  Further, according to the present invention, since the cross-sectional shapes of the cassette intermediate container and the outer container are different, a space is reliably secured between the two, and the trunk portion of the outer container is unintentionally intended. Even if there is a possibility of gripping, the space can buffer the gripping force, so that the cassette intermediate container is not directly pressed, and accidental pop-out of the package filled in the package can be prevented. It can be blocked enough. That is, in the cassette type liquid material filling composite container of the present invention, a two-step pressing operation (two-step push motion) is required when discharging the package, and the composite container is lifted while being gripped with fingers in the first step. (At this time, the package does not pop out even if the force is applied too much.) In the second step, it was intended for the first time by pressing the body of the composite container with fingers slowly until reaching the cassette intermediate container Discharge can be obtained.

  Further, according to the present invention, since the non-self-supporting package is surrounded by the intermediate cylinder having a flat cross-sectional hexagonal shape, the above-mentioned outer container can be tilted or the like when the packaged material is poured out. The package does not slip in the tilting direction, and the packaged material can be poured out while controlling the pouring amount to the end.

  Further, according to the present invention, by providing at least a pair of bottom plates that project in the diagonal direction at the lower end portion of the intermediate cylinder, it is possible to provide self-supporting property to the intermediate cylinder, and to the inside of the intermediate cylinder. Since both side edges of the lower end of the package to be locked can be prevented from protruding outward, the side edge of the lower end of the package jumps out when the cassette intermediate container is fitted into the outer container. Can be prevented, and the self-supporting property of the cassette type liquid material filling composite container can be improved. The self-supporting property of the cassette type liquid material filling composite container of the present invention can be improved also when a removable bottom frame is provided on the bottom of the outer container.

  Further, according to the present invention, since the cassette intermediate container and the outer container can be firmly fixed by integrating the hooking piece provided in each and the hooking hole, the both can be firmly fixed. It is possible to prevent the cassette intermediate container from falling off or falling off from the outer container.

  Further, according to the present invention, the cassette middle container is provided from the bottom of the outer container by providing a pair of holding claws on the upper inner surface of the outer container and holding the upper end of the intermediate cylinder by the holding claws. As the cassette intermediate container can be easily mounted and removed in the outer container, the replacement operation can be simplified.

In the present invention, when a plurality of slits are provided in the lower part of the body portion of the outer container, the slit portion is deformed preferentially when the outer container is pressed with fingers, so other parts are intended. While being able to control that deformation, breakage, etc. can be suppressed, the remaining amount of the package can be checked visually from the slit portion.
Further, even when a plurality of slits are provided at predetermined intervals in the longitudinal direction on at least one of the side portions of the outer container, the same effect as described above can be expected, and the side position of the outer container is Even if the outer container is made of a rigid material, it can be easily crushed and crushed until it becomes flat, and the liquid in the package can be pushed out by pressing with fingers.

  Further, according to the present invention, the dispensing nozzle provided at the top or side of the package body is provided with a pressing portion which extends across the dispensing passage and functions as a seal valve. The soft films are brought into close contact with each other, and the pouring passage is shut off, so that even if the outer container is accidentally collapsed, the possibility of leakage of the package can be sufficiently eliminated.

  In particular, since the pressing portion is provided within 4 mm from the planned planned position of the tip opening of the pouring nozzle, the liquid or viscous package-like material remaining in the vicinity of the tip opening when the soft films on the front and back adhere closely. As a result, it is possible to sufficiently eliminate the risk of dropping the package.

  The pressing section presses one of the front and back soft films toward the other, presses the front and back soft films in the same direction, or presses the front and back films in the opposite direction. It can be formed, for example, as a bent portion or inflection portion having a cross-sectional mountain shape or a cross-sectional trapezoidal shape. In this pressed portion, the soft films on the front and back sides constituting the bent portion or inflection portion are separated from each other by the hydraulic pressure and extended when the packaged object is discharged. The soft films on the front and back sides return to their original shape by elastic restoring force with the stop (non-pressurized) of the discharge of the ink, and they adhere closely to each other in a line or plane and automatically the pouring passage of the pouring nozzle It is effective to shut off.

  In addition, if the said pressure processing part stops discharge of a package thing, the soft film of the front and back will be quick by elastic restoring force with the fall of the liquid pressure of the liquid or viscous package thing in a pouring passage. If the pouring nozzle has a self-sealing function (non-return function), the adhesion between the inner surfaces of the non-pouring nozzle inside the pouring passage becomes faster and more reliable, and the self-sealing function It can be improved. Therefore, in this case, the non-return injection nozzle can exhibit the two-stage sealing function by the self-sealing function and the pressing portion which is a seal valve.

It is a figure which shows one Embodiment of a cassette intermediate | middle container, (a) is a front view, (b) is a right view, (c) is a bottom view of an intermediate cylinder. It is a figure showing one embodiment of a packaging bag which has a pouring nozzle. It is a figure which shows the cross section of the press process part which follows the BB line of FIG. 3, (a) consists of a mountain-shaped variation part, (b) consists of a trapezoidal-shaped bending part. It is an expanded view of an intermediate cylinder. It is an end elevation which meets the AA line of FIG. 1, (a) shows the case where a clamping surface becomes uneven | corrugated shape, when (b) the clamping surface of a clamping nail | claw is flat. It is a right view which shows other embodiment of an outer container. An embodiment of a bottom frame attached to a bottom of an outer container is shown, and (a) is a top view and (b) is a front view.

  FIG. 1 shows an embodiment of a cassette type liquid filling composite container C for liquid filling according to the present invention, wherein (a) is a front view, (b) is a right side view, and (c) is a front view. It is a bottom view. The cassette type liquid material filling composite container C is composed of an outer container 16 and a cassette intermediate container 10 shown by a dotted line in the figure. For example, the bottom opening of the cylindrical outer container 16 is at the top of the cassette intermediate container 10 By pressing and fitting, the outer container 16 and the cassette intermediate container 10 can be easily integrated.

  First, the cassette intermediate container 10 constituting the cassette type liquid material filling composite container C will be described. The cassette intermediate container 10 is composed of a package 4 and an intermediate cylinder 9 for containing the package 4 as shown in FIG. 2, and they are integrated by locking 9a by hot melt, heat fusion or the like. Be done. In the figure, the package 4 and the intermediate cylinder 9 are engaged 9a at two places, but at least one place of the upper end of the package 4 may be engaged, preferably near the pouring nozzle 1 Lock at.

  The package 4 is filled with a liquid or viscous package such as food, drink, medicine, or cosmetics into the packaging bag 3 shown in FIG. 3 provided with the dispensing nozzle 1 protruding from the top of the packaging bag body 2. It is formed by doing. Note that the dispensing nozzle 1 may be provided so as to protrude from the side portion of the packaging bag main body 2, and in any case, the sealant layer on the outer surface of the proximal end portion 1 a of the dispensing nozzle 1 It is fused and bonded to the inner surface of

  Further, the pouring nozzle 1 is divided into the pouring passage 6 in the central part by the heat sealing part 5 in the peripheral part, and formed from the V-shaped notch 7 formed at the tip of the heat sealing part 5, for example. The tip opening 8 is formed by cutting the tip portion of the outlet passage 6 with, for example, a finger.

Furthermore, the pouring nozzle 1 is preferably provided with a pressing portion 28 at a position within 4 mm from the position where the tip opening 8 is formed. The pressing portion 28 has, for example, a cross-sectional shape corresponding to a required shape. By pressing and heating the laminated films 30, 31 on the front and back in the same direction or in directions opposite to each other at a required temperature and pressure to bend or inflect, for example, line B-B in FIG. As shown in the cross-sectional view (FIG. 4) at the position, it can be composed of a bent portion of a cross-sectional mountain shape (FIG. 4 (a)) or a bent portion of a trapezoidal cross-section (FIG. 4 (b)).
In addition, even if the pressed portion 28 is configured by, for example, heating and pressing one laminated film 30 of the front and back laminated films 30 and 31 toward the other laminated film 31 to cause bending or bending. Good.

  In the press-processed portion 28 formed of the bent portion or inflection portion formed in this manner, the laminated films 30, 31 on the front and back sides are separated from each other by the fluid pressure of the packaged object when the packaged material is poured out. In the stretched state, when the pouring out of the packaged product is stopped (unpressurized), the elastic restoring force returns to the original shape and adheres to each other linearly or in a planar manner. The pouring passage 6 can be shut off automatically.

  By using the pouring nozzle 1 having the pressing part 28 in the pouring passage 6 as described above, the inside of the package 4 when the outer container 16 is unintentionally held in the composite container C for filling a cassette type liquid material. In addition to effectively preventing accidental popping out of the package material, it is possible to suppress leakage of the package material from the tip opening 8 even if the cassette type composite container C for liquid material filling unexpectedly falls. can do.

  Here, the pressing portion 28 is provided such that the distance (X) from the tip opening 8 is within 4 mm as described above. This is because the distance between the front and back laminated films 30, 31 is in close contact with each other at a position near the tip opening 8 by setting the distance (X) within 4 mm, and the function as a seal valve is exhibited. Unforeseen leak of the package at the time of tipping of the container C or the like can be suppressed.

In addition, when the dispensing nozzle 1 has a self-sealing function, when the outer container 16 is raised and returned along with the stop of the discharge of the packaged object, the laminated films 30, 31 on the front and back of the pressing portion 28 are mutually Since the package remaining in the pouring passage 6 and in the vicinity of the tip opening 8 is exposed to negative pressure associated with the reduced pressure atmosphere in the packaging bag body 2 before being closely attached to the packaging bag body 2, it is drawn into the packaging bag body 2. It is more preferable because it is possible to effectively suppress the drop from the tip opening 8.
The self-sealing function refers to the simultaneous termination of the pouring of the liquid or viscous packaged material due to the shrinkage or deformation of the packaging bag body 2 itself when the packaged material in the package 4 is dispensed. The inner surfaces of the pouring passage 6 of the pouring nozzle 1 wetted by the liquid or viscous package are automatically brought into close contact with each other under the presence of the thin film by the package, and are inserted into the package 4. It is a non-return function that prevents outside air from entering.

When the distance (X) between the pressing portion 28 and the tip opening 8 is more than 4 mm, when the discharge of the packaged material is stopped, there are many packaged objects remaining in the tip opening 8 and the vicinity thereof. As a result, the package can not be drained into the packaging bag main body 2 and it is easy for the dropout to occur.
On the other hand, if the distance (X) from the pressing portion 28 to the tip opening 8 is too short, the required rigidity can not be imparted in the vicinity of the tip opening 8 and the pouring passage 6 may not be blocked. It is more preferable to set the distance (X) to 1 mm or more and 4 mm or less because there is a possibility that the leakage of the packaged material can not be reliably prevented when the composite container C for liquid filling with a liquid falls or the like.

  In addition, the pouring nozzle 1 is comprised from the flat laminated film of a three or more-layered laminated structure provided with the base film layer and the non-stretching sealant layer each laminated | stacked on the front and back which pinches this base film layer. The base film layer can be composed of a known polyester film, nylon film or ethylene vinyl copolymer film, and the non-stretchable sealant layer can also be a polyethylene, polypropylene, ionomer or ethylene vinyl acetate copolyester which is also known. It can be made of a polymer, and any of these can provide the required rigidity by the pressing portion 28 within 4 mm from the tip opening 8.

It is preferable that the pressing portion 28 is formed of 1 to 3 bends or inflection portions having a cross-sectional mountain shape or a cross-sectional trapezoidal shape extending across the pouring passage 6. When three or more bent portions or inflection portions are formed including semicircular shapes, the adhesion of the laminated films 30, 31 in the vicinity of the tip opening 8 becomes too high, and flows from the packaging bag main body 2 side. It is not possible to separate the laminated films 30, 31 on the front and back sides from each other due to the liquid pressure (self weight) of the packaged material, and it becomes difficult to open the pouring passage 6 freely and to freely pour the packaged material. It is because
Here, when the pressing portion 28 has a trapezoidal cross-sectional shape as shown in FIG. 4B, the distance (Y) between adjacent two ridge lines 29 is 0.5 mm for securing rigidity. It is preferable to set it as the following. In other words, if the spacing (Y) between the ridge lines is too large, the elastic restoring force of the pressing and pressing unit 28 will be insufficient, and the leakproof function and the like will not be sufficiently exhibited.

  In such a pouring nozzle 1, the cassette type liquid material filling composite container C exceeds 75 degrees from the standing posture, on the condition that a packaged object of 1/5 or more remains in the packaging body 4, for example. When the container is tilted, the hydraulic pressure of the package is higher than the adhesion of the pressing portion 28 and can be naturally poured out from the pouring passage 6 facing downward, while the tilting angle is 75 The pouring can be stopped by tilting back so that it becomes less than a degree.

  If the tilt angle (angle between the floor and the bottom of the composite container C) from the standing posture of the cassette type liquid container C is less than 75 degrees, the cassette type liquid container C is By pressing the body directly or indirectly until it reaches the cassette intermediate container 10, the material in the bag can be poured out as required. Similarly, even if the volume of the package such as soy sauce in the package 4 is significantly reduced, for example, to less than 1/5, the cassette type liquid filling composite container C is tilted at an angle of more than 75 degrees. If the package can not be lubricated and poured out sufficiently, the body of the cassette type liquid material filling composite container C is pressed directly or indirectly until it reaches the cassette intermediate container 10 And performs the pouring according to the requirement of the package. Also in the case of this pressing, it is preferable that the cassette type liquid material filling composite container C be in a tilting posture in order to specify the pouring position.

The tilt angle of the cassette type liquid material filling composite container C and the pouring state of the package can be adjusted by adjusting the adhesion length in the discharge direction of the pressing portion 28, and the adhesion length is 0. It is preferable that it is 5.5-10.0 mm, More preferably, it is 0.5-5.0 mm.
This is because if the adhesion length is less than 0.5 mm, the contact between the laminated films 30, 31 on the front and back sides at the position of the pressing portion 28 is too small, and the adhesion is insufficient, and the composite container C for cassette type liquid filling When they fall over etc., they both separate easily and can not exhibit a leakproof function, while on the other hand, if it exceeds 10.0 mm, the adhesion of the laminated films 30, 31 on the front and back becomes strong This is because it is necessary to strongly press the body of the composite container C for filling a cassette type liquid when discharging the liquid or viscous package, and it becomes difficult to freely pour out.

  As shown in FIG. 2, the upper end portion of the intermediate cylinder 9 has a substantially plate-like shape, and the trunk portion has a substantially flat cross-sectional hexagonal shape via the mountain fold line 9b. The intermediate cylinder 9 has a notch 9c at the upper side, and the pouring nozzle 1 is configured to project from the notch 9c. A protective piece 12 is provided in this notch 9c as shown in the developed view of FIG. 5 to protect the pouring nozzle 1 from the front and back until the start of use, and to prevent the bending, breakage or the like of the pouring nozzle 1 You may The intermediate cylinder 9 can be formed of paper, plastic, or the like, and any material can be used as long as it can impart regularity to the package 4.

  It is preferable to provide at the lower end portion of the intermediate cylinder 9 at least a pair of flange-like bottom plates 11 projecting in the direction of a long diagonal as shown in the bottom view of FIG. The container 10 can be made self-supporting. Further, since the bottom plate 11 can prevent the lower end side edge portion of the package 4 from protruding from the cassette intermediate container 10, it is possible to exhibit the effect of suppressing the decrease in the self-supporting property of the cassette intermediate container 10. .

  The intermediate cylinder 9 can be easily assembled, for example, by bending a sheet 13 shown in FIG. 5 along a mountain fold line 9b. Here, the projecting pieces 14 and 15 projecting from the lower end edge of the sheet material 13 form the pair of bottom plates 11. When assembling the intermediate cylinder 9, the projecting pieces 14 and the projecting pieces 15 are used as a sheet. The bottom plate 11 can be easily formed by folding the inside of the intermediate cylinder 9 along the fold line 26 provided at the lower end edge of the material 13.

In addition, it is preferable to provide mountain fold lines 14a and 15a and valley fold lines 14b and 15b, which are formed by cutting or the like, on the protrusions 14 and 15 respectively. According to this, when the projecting piece 14 and the projecting piece 15 are folded along the fold line 26 into the inside of the intermediate cylinder 9 as described above, naturally along the mountain fold lines 14a, 15a and the valley fold lines 14b, 15b Even if the protrusion 14 and the protrusion 15 are folded, and the bottom plate 11 may slip off the bottom due to the weight of the package 4 or an impact during handling, the protrusions 14 and 15 may be used as a table surface. The bottom plate 11 can be easily folded into the inside of the intermediate cylinder 9 simply by pressing it to the lower side.
The intermediate cylinder 9 can be formed not only by using the sheet material 13 as shown in FIG. 5 but also integrally by blow molding or the like.

Next, the outer container 16 will be described.
As can be seen from the bottom view of FIG. 1 (c), the outer container 16 has a cross-sectional shape of the trunk gradually expanding from the pointed end 16a, and the tail end 16b has an arc-like waterdrop or teardrop shape The cassette intermediate container 10 is fitted so that the pouring nozzle 1 of the cassette intermediate container 10 is positioned on the side of the pointed head 16a. Thereby, in use, the arc-shaped portion on the side of the tail end 16b of the outer container 16 is gripped so that the fitting to the fingers is good, and the package can be poured out while being gripped firmly.

  Since the outer container 16 and the cassette intermediate container 10 have different cross-sectional shapes at the body position, as shown in FIG. 1B, when the cassette intermediate container 10 is fitted in the outer container 16, the cassette intermediate container 10 is inserted. A space 17 is to be formed between the and the outer container 16. Therefore, even if the outer container 16 is gripped without manual adjustment, the space 17 functions as a buffer layer, and the pressing force is not directly applied to the cassette intermediate container 10, and the unexpectedness of the package in the package 4 Can be effectively prevented.

  The outer container 16 is formed of a material having high rigidity, for example, plastic such as biomass polyethylene or paper so that the outer container 16 can be recycled and used a plurality of times by replacing the cassette intermediate container 10 fitted inside. It is preferable to do.

  As shown by a phantom line (two-dot chain line) in FIG. 1A, the outer container 16 is provided with a pivot pin or the like so as to cover the pouring nozzle 1 at the protruding position of the pouring nozzle 1 of the cassette middle container 10. A cap 27 which can be pivoted may be provided, and the cap 27 can prevent the discharge nozzle 1 from being exposed to the outside during storage of the cassette type liquid filling composite container C or the like. There is no possibility that dust, bacteria, etc. will adhere to the pouring nozzle 1, and it is possible to suppress the contamination of the pouring nozzle 1 and the package in the bag.

  The outer container 16 may be formed to have substantially the same width up to the upper portion, as well as a shape that gradually narrows toward the upper portion as shown in FIG. 1 (b). The outer container 16 is provided with a pair of holding claws 32 on the upper inner surface of the outer container 16 as shown in the end view (FIG. 6) at the A-A position in FIG. When the upper end (plate-like portion) of the intermediate cylinder 9 of the cassette intermediate container 10 is inserted and held between the two 32, the cassette intermediate container 10 can be easily fixed in the outer container 16. The cassette intermediate container 10 can be prevented from falling off or falling off. In addition to the clamping jaws 32 having a flat clamping surface as shown in FIG. 6 (a), the clamping jaws 32 have a sawtooth-shaped unevenness as shown in FIG. 6 (b). Thus, the slippage of the upper end of the held intermediate cylinder 9 can be effectively suppressed.

  For example, as shown in FIG. 1A, the intermediate cylinder 9 of the cassette intermediate container 10 is provided with the engagement holes 18, while the outer container 16 is provided with the engagement pieces 19, and the cassette intermediate container 10 is fitted in the outer container 16. When the hooking hole 18 and the hooking piece 19 are fitted when inserted, it is possible to effectively prevent the cassette intermediate container 10 from falling off or falling off the outer container 16. The hooking holes 18 and the hooking pieces 19 may be provided in the opposite members, respectively, and the positions where the hooking holes 18 and the hooking pieces 19 are formed are not particularly limited.

  In another embodiment of the outer container 16 of FIG. 7, three slits 33 are provided at intervals in the longitudinal direction on the side of the tail end side 16b. It is preferable that a plurality of the slits 33 be provided on at least one of the sharp head side 16 a and the tail end side 16 b of the outer container 16. The slits 33 make it easy to fold the sides of the outer container 16 and the outer container 16 can be crushed to a flat surface even when the outer container 16 is made of a rigid material. By pressing the part with fingers, the package in the package 4 can be pushed out to the end, and the remaining amount can be reduced.

  In addition, maintenance and self-supporting of the shape of the outer container 16 having a substantially water droplet-like or teardrop-like outer contour shape as a whole, for example, providing one or more thickened portions at the lower end of the outer container 16 or FIG. ) By making the widthwise central portion of the front and back of the outer container 16 in a band shape (thick portion 16c) from the lower end to a height of at least 1/3 of the outer container 16 Besides, it can also be performed by fitting a bottom frame 20 as shown in FIG. 8 to the lower end of the outer container 16.

  In the case where the front and back central portions of the outer container 16 are formed in a band-like thick portion 16c, when the body of the outer container 16 is held in use, the holding force is directly determined by the rigidity of the thick portion 16c. There is no possibility that the material to be packaged may be accidentally ejected while the material is not transferred to the cassette intermediate container 10, but when the thick portion 16c is pressed with a finger when discharging the material, not only the pressed portion but also a thick portion in strip shape. Since the whole 16c acts (moves) in the pressing direction, even when the remaining amount of the package in the package 4 is reduced, the package can be discharged with a small pressing force.

  For example, as shown in FIG. 8, the bottom frame 20 can be attached by fitting the hooking projections 21 provided on the peripheral edge thereof into hooking holes (not shown) provided on the outer container 16.
