Description

  This invention makes it easy to replace a package filled with a liquid or viscous liquid food or drink, chemical, pharmaceutical, cosmetic or the like, and even if the container is held firmly, The present invention relates to a cassette type liquid material filling composite container capable of preventing the packaged material made of the liquid material from unexpectedly popping out.

  2. Description of the Related Art Conventionally, liquid packaging containers made up of a soft packaging bag and an outer container that supports the flexible packaging bag are well known in which an inner container (bag) and an outer container are integrated.

  For example, there are those disclosed in Patent Document 1 and Patent Document 2 for the pouring nozzle made of a soft film and the packaging bag having the same. The packaging bags disclosed in these documents prevent the outside nozzle from entering the packaging bag before and after the dispensing, as well as during the dispensing of the liquid packaged items in the packaging bag. It has a self-sealing function, and is configured such that a liquid package can be easily poured out by tilting the packaging bag from the tip of the dispensing nozzle.

  However, all of these packaging bags are made of a soft film, and a packaging body filled with a liquid material in the packaging bag is neither self-supporting nor formable. Therefore, it is necessary to provide a hard outer container for providing self-supporting property, and it is usually provided in a manner that is integrally and inseparable within the outer container, that is, as a fixed and combined product. As such an outer container, for example, the one shown in Patent Document 3 has been proposed.

Japanese Patent No. 4392198 Japanese Patent No. 4996815 Japanese Patent No. 5669981

  The outer container of Patent Document 3 is configured so that the stored non-self-supporting package is sandwiched and fixed in the outer container at the upper end position of the package. Therefore, when the remaining amount of the package is reduced, and the angle for tilting the outer container is increased when the package is poured out, the bottom of the package body slides toward the top of the outer container. In some cases, a large amount of the packaged material is poured out, or the amount of the packaged product dispensed cannot be controlled.

  Further, the outer container of Patent Document 3 seals the dispensing passage of the dispensing nozzle by tightening means, thereby preventing leakage of the packaged object against unintended collapse after opening the tip of the dispensing nozzle. However, when the outer container is grasped without being adjusted with the tightening means removed, there is a possibility that the packaged items may pop out and the surroundings may be soiled.

  Accordingly, a first object of the present invention is to provide a cassette type liquid material filling composite container in which only the inner package (packaging bag + liquid material) can be easily replaced. In addition, the second object of the present invention is to sufficiently prevent unintentional popping out of the packaged item even when the outer container is grasped without any control, and the amount of the packaged item to be dispensed by hand. 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.

  During research aimed at realizing the above object, the inventor has come up with the present invention according to the following gist configuration. That is, in the present invention, a film-like pouring nozzle made of a soft film is formed by filling a liquid or viscous packaged article into a packaging bag protruding from the side or top of a soft packaging bag body. A package and an intermediate cylinder having a hexagonal cross section whose upper end is substantially plate-shaped and whose body is substantially flat via a mountain fold line, and at least a part of the upper end of the package is engaged with the inside of the intermediate cylinder. The cassette intermediate container is composed of a cassette intermediate container that is stopped and integrated, and an outer container in which the cross-sectional shape of the body portion is in the form of a water drop or a tear drop, and the cassette intermediate container is detachably fitted into the outer container. The gist of the present invention is a composite container for filling a cassette type liquid material.

The present invention also provides:
(1) The intermediate cylinder has a pair of inwardly flanged bottom plates protruding in a diagonal direction at a lower end portion;
(2) The intermediate cylinder and the outer container include an engagement piece provided in either the intermediate cylinder or the outer container, and an engagement hole provided in the other of the intermediate cylinder or the outer container. And is detachably fitted,
(3) The outer container has a pair of clamping claws for clamping the upper end of the intermediate cylinder from both sides on the inner surface of the upper end.
(4) The outer container is fitted with a detachable bottom frame at the lower end,
(5) The outer container is provided with a plurality of slits extending in the lateral direction at the lower portion of the trunk,
(6) The outer container is provided with a plurality of slits at predetermined intervals in the vertical direction on at least one side.
(7) The pouring nozzle is made of a soft laminated film having a laminated structure, and in the state where the laminated film is superposed on the front and back, the center portion is poured out by heat fusion at the peripheral portion except for the base end portion. It is defined as a passage, and extends across the pouring passage from the planned opening position formed across the pouring passage to a position on the distal end side within 4 mm toward the base end side. A pressing portion for blocking the pouring passage by mutual adhesion of the laminated films is provided, and the pressing portion is applied to the liquid pressure of the liquid or viscous packaged material flowing from the packaging bag body side. According to the above, the front and back laminated films are separated from each other to be a seal valve that opens the extraction passage,
(8) The pouring nozzle pours a liquid or viscous packaged article in the packaging bag body without inhaling outside air by tilting the packaging bag body or pressing the body of the packaging bag body. In addition, when stopping the pouring based on the rising and returning of the packaging bag main body or the release of the pressure to the packaging bag main body, the inner surface of the pouring passage of the pouring nozzle is placed on the liquid or viscous packaged object. Having a self-seal function to prevent the outside air from entering the packaging bag body by sealing immediately under the intervention of a thin film;
It is considered that adopting the above becomes a more preferable solution.

  The first feature of the present invention resides in that the cassette type liquid material filling composite container according to the above-described gist configuration is employed. According to the composite container having such a configuration, since the entire cassette intermediate container is exchanged, it is not necessary to handle a package that is neither fixed nor self-supporting as in the prior art, and the customer himself / herself is safe. In addition to being able to perform the replacement work in mind, it is not necessary to align the pouring nozzle, and the replacement work can be performed simply by fitting the cassette intermediate container into the outer container. In other words, according to the present invention, it is possible to easily replenish the packages by simply taking out the cassette intermediate container from the outer container and replacing it with a new one.

  In addition, according to the present invention, since the cassette intermediate container and the outer container have different cross-sectional shapes, a space is surely ensured between the two, and the body of the outer container is unintentionally attached. Even if there is a case of gripping, the gripping force can be buffered by the space, so that the cassette intermediate container is not directly pressed, and unexpected popping out of an object to be packed filled in the package body is prevented. It can be sufficiently blocked. That is, in the composite container for filling a liquid cassette according to the present invention, a two-stage pressing operation (two-stage push motion) is necessary for discharging the packaged object, and the composite container is lifted while holding it with fingers in the first stage. (At this time, the packaged item will not pop out even if too much force is applied) It was intended for the first time by slowly pressing the body of the composite container with fingers until it reaches the cassette intermediate container at the second stage. 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 hexagonal cross section, when the package is poured out, the outer container is tilted or the like. The package does not fall down in the tilting direction, and the packaged product can be poured out while controlling the amount of dispensing.

  Further, according to the present invention, by providing at least a pair of bottom plates projecting diagonally at the lower end portion of the intermediate cylinder, the intermediate cylinder can be provided with self-supporting properties, and on the inner side of the intermediate cylinder Since both side edges of the lower end of the package body to be locked can be prevented from projecting to the outside, the side edge of the lower end of the package body pops out when the cassette intermediate container is fitted into the outer container. 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 even when a detachable bottom frame is provided at the bottom of the outer container.

  In addition, according to the present invention, the cassette intermediate container and the outer container can be firmly fixed by integrating the engaging pieces provided with the engaging pieces and engaging holes, respectively, It is possible to prevent the cassette intermediate container from slipping off or dropping off from the outer container.

  Further, according to the present invention, a pair of clamping claws are provided on the inner surface of the upper end of the outer container, and the upper end of the intermediate cylinder is clamped by the clamping claws, so that the cassette intermediate container is removed from the bottom of the outer container. Both of them can be easily fixed simply by fitting them, and the cassette intermediate container can be easily attached to and detached from the outer container, so that the replacement work can be simplified.

Further, in the present invention, when a plurality of slits are provided in the lower portion of the body portion of the outer container, when the outer container is pressed with fingers, the slit portion is preferentially deformed, so other portions are intended. It is possible to suppress deformation and breakage, and to visually check the remaining amount of the package from the slit portion.
In addition, when at least one of the body side portions of the outer container is provided with a plurality of slits at predetermined intervals in the vertical direction, the same effect as described above can be expected, and the side position of the outer container is Even when the outer container is made of a material having rigidity, it can be easily folded and crushed until it becomes flat, and the liquid in the package can be pushed out to the end by pressing with a finger.

  Further, according to the present invention, the dispensing nozzle protruding from the top or side of the package is provided with a pressing portion that extends across the dispensing passage and functions as a seal valve. Even if the soft film is brought into close contact with each other, the discharge passage is blocked, and the outer container is inadvertently laid down, the risk of leakage of the package can be sufficiently eliminated.

  In particular, since a pressing portion is provided at a position within 4 mm from the position where the tip opening of the pouring nozzle is to be formed, a liquid or viscous packaged object that remains in the vicinity of the tip opening when the front and back soft films are in close contact with each other There is little, and the possibility of dropping off the package can be sufficiently removed.

  In addition, the said press processing part 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 a direction facing each other. For example, it can be a bent portion or a bent portion having a mountain-shaped cross section or a trapezoidal section. When the packaged object is discharged, the soft film on the front and back constituting the bent part or the inflection part is separated from each other by the hydraulic pressure and is stretched. The soft film on the front and back returns to the original shape due to the elastic restoring force as the discharge stops (unpressurized), and the discharge passage of the discharge nozzle is automatically brought into close contact with each other in a linear or planar shape. Effective for blocking.

  Note that when the discharge of the packaged article is stopped, the pressing processing unit quickly causes the soft films on the front and back sides to quickly move due to the elastic restoring force as the liquid pressure of the liquid or viscous packaged article in the dispensing passage decreases. If the dispensing nozzle has a self-seal function (non-return function), the surface of the non-return dispensing nozzle in the dispensing passage is more quickly and reliably adhered to the self-sealing function. Can be improved. Therefore, in this case, the non-return dispensing nozzle can exhibit a self-sealing function and a two-stage sealing function by the pressing portion that is a sealing valve.

It is a figure which shows one Embodiment of a cassette intermediate container, (a) is a front view, (b) is a right view, (c) is a bottom view of an intermediate | middle cylinder. It is a figure which shows one Embodiment of the packaging bag which has an extraction nozzle. It is a figure which shows the cross section of the press work part in alignment with the BB line of FIG. 3, (a) consists of a mountain-shaped transformation part, (b) consists of a trapezoidal bending part. It is an expanded view of an intermediate | middle cylinder. 2A and 2B are end views taken along line AA in FIG. 1, in which FIG. 1A illustrates a case where the clamping surface of the clamping claw is flat, and FIG. It is a right view which shows other embodiment of an outer container. One Embodiment of the bottom frame attached to the bottom part of an outer container is shown, (a) is a top view, (b) is a front view.

  FIG. 1 shows one embodiment of a composite container C for filling a liquid material of the present invention, wherein (a) is a front view, (b) is a right side view, and (c) is a side 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 indicated by a dotted line in the figure. For example, the bottom opening of the cylindrical outer container 16 is formed at the upper portion 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. As shown in FIG. 2, the cassette intermediate container 10 is composed of a packaging body 4 and an intermediate cylinder 9 for housing the packaging body 4, and the two are integrated by locking 9a by hot melt, heat fusion or the like. Is done. In the figure, the packaging body 4 and the intermediate cylinder 9 are locked at two locations 9a, but it is sufficient that they are locked at at least one location on the upper end of the packaging body 4, and preferably in the vicinity of the pouring nozzle 1 To lock.

  The package 4 is filled with a liquid or viscous packaged material such as food, drink, medicine, cosmetics, etc. in 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. The pouring 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 base end portion 1 a of the pouring nozzle 1 is used as the packaging bag main body 2. Fused to the inner surface and bonded.

  Further, the pouring nozzle 1 has a pouring passage 6 defined in the central portion by the thermal fusion portion 5 at the peripheral portion, and is poured from, for example, a V-shaped notch 7 formed at the distal end portion of the thermal fusion portion 5. The front end opening 8 is formed by excising the front end portion of the exit passage 6 with, for example, fingers.

Further, the dispensing 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 pressing the laminated films 30 and 31 on the front and back sides in the same direction or in opposite directions with the required temperature and pressure by the pressing blade and bending or bending, for example, the line BB in FIG. As shown in the cross-sectional view at the position (FIG. 4), it can be composed of an inflection portion having a cross-sectional mountain shape (FIG. 4A), a bent portion having a cross-sectional trapezoidal shape (FIG. 4B), or the like.
In addition, you may comprise the press process part 28 by making one laminated | multilayer film 30 out of the laminated films 30 and 31 of the front and back, for example, heating and pressurizing toward the other laminated | multilayer film 31, and making it bend or bend. Good.

  In the pressing portion 28 formed of the bent portion or the inflection portion formed in this way, the front and back laminated films 30 and 31 are separated from each other by the liquid pressure of the article to be packaged when the article to be packaged is poured out. Although it will be in an extended state, it will return to its original shape by elastic restoring force with the stoppage (unpressurization) of the article to be packaged, and will adhere closely to each other in a linear or planar shape. The dispensing passage 6 can be automatically shut off.

  If the pouring nozzle 1 having the pressing portion 28 in the pouring passage 6 is used, the inside of the package 4 when the outer container 16 is unintentionally gripped in the cassette type liquid material filling composite container C. In addition to effectively preventing unintentional pop-out of the packaged item, even if the cassette type liquid material filling composite container C falls down unexpectedly, leakage from the front end opening 8 of the packaged item is suppressed. can do.

  Here, as described above, the pressing portion 28 is provided so that the distance (X) from the tip opening 8 is within 4 mm. This is because when the distance (X) is within 4 mm, the front and back laminated films 30 and 31 are brought into close contact with each other in the vicinity of the tip opening 8 and function as a seal valve. Unexpected leakage of the packaged item when the container C falls can be suppressed.

In addition, when the dispensing nozzle 1 has a self-seal function, when the outer container 16 is raised and returned along with the stop of the discharge of the packaged article, the laminated films 30 and 31 on the front and back sides at the position of the pressing portion 28 are mutually connected. Since the articles to be packaged remaining in the dispensing passage 6 and in the vicinity of the tip opening 8 are exposed to the negative pressure associated with the reduced pressure atmosphere in the packaging bag body 2 before being in close contact with the packaging bag body 2, It is more preferable because it is possible to effectively suppress the dropping of the potter from the tip opening 8.
The self-sealing function means that when the packaged article in the package 4 is poured out, the packaging bag body 2 itself is contracted or crushed to stop the liquid or viscous packaged article being poured. The inner surfaces of the dispensing passage 6 of the dispensing nozzle 1 wetted by the liquid or viscous packaged object are automatically brought into close contact with each other through the thin film formed by the packaged object, and are introduced into the package 4. It is a check function that prevents outside air from entering.

When the distance (X) between the pressing portion 28 and the tip opening 8 exceeds 4 mm, when the discharge of the article to be packaged is stopped, there are many articles to be packaged remaining in the tip opening 8 and the vicinity thereof. Thus, the article to be packaged cannot be liquid-drawn into the packaging bag main body 2, and it becomes easy to cause dropping of the pot.
On the other hand, if the distance (X) from the pressing portion 28 to the tip opening 8 is too short, the required rigidity cannot be imparted in the vicinity of the tip opening 8 and the dispensing passage 6 may not be blocked, and the cassette The distance (X) is more preferably 1 mm or more and 4 mm or less because there is a possibility that leakage of the packaged object may not be reliably prevented when the composite container C for filling a liquid material is overturned.

  In addition, the pouring nozzle 1 is composed of a flat laminated film having a laminated structure of three or more layers including a base film layer and unstretched sealant layers laminated on the front and back sides of the base film layer. This base film layer can be composed of a known polyester film, nylon film or ethylene vinyl copolymer film, and the unstretched sealant layer can also be a known polyethylene, polypropylene, ionomer or ethylene vinyl acetate copolymer. Any one of these can be used to provide the required rigidity by the pressing portion 28 within 4 mm from the tip opening 8.

It is preferable that the press processing part 28 consists of a bending part or an inflection part of the cross-section mountain shape or cross-sectional trapezoid shape of 1 to 3 extending across the extraction channel | path 6. FIG. This is because, when three or more bent portions or inflection portions are formed including a semicircular shape, the adhesive force of the laminated films 30 and 31 in the vicinity of the tip opening 8 becomes too high and flows from the packaging bag body 2 side. The laminated film 30 and 31 on the front and back sides cannot be separated from each other due to the hydraulic pressure (self-weight) of the packaged article, and it is difficult to freely open the dispensing passage 6 and to freely dispense the packaged article. Because it becomes.
Here, when the pressing portion 28 has a trapezoidal cross section as shown in FIG. 4B, the adjacent interval (Y) of the two ridge lines 29 is set to 0.5 mm to ensure rigidity. The following is preferable. In other words, if the adjacent interval (Y) between the ridge lines becomes too large, the elastic restoring force of the pressing and pressing unit 28 is insufficient, and the leakage prevention function and the like are not 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 condition that, for example, 1/5 or more of an object to be packaged remains in the package 4. When tilted, the liquid pressure of the article to be packaged is higher than the adhesive force of the pressing part 28 and can be naturally poured out from the pouring passage 6 facing downward, while the tilt angle is 75. The pouring can be stopped by returning the tilt so as to be less than or equal to the degree.

  When the tilt angle from the standing posture of the cassette-type liquid material filling composite container C (the angle between the floor surface and the bottom surface of the composite container C) is 75 degrees or less, the cassette-type liquid material filling composite container C By pressing the barrel directly or indirectly until it reaches the cassette intermediate container 10, the packaged item in the bag can be poured out as required. Similarly, even if the volume of the packaged object such as soy sauce in the package 4 is significantly reduced to, for example, less than 1/5, the cassette type liquid material filling composite container C is tilted at an angle exceeding 75 degrees. If the packaged article cannot be smoothly and sufficiently poured out, 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. Then, the packaged material is dispensed as required. Even in the case of this pressing, it is preferable that the cassette type liquid material filling composite container C is tilted in order to specify the pouring position.

The tilt angle of the cassette-type liquid material filling composite container C and the state of the package to be poured can be adjusted by adjusting the contact length in the discharge direction of the pressing portion 28, and the contact length is 0. It is preferably 5 to 10.0 mm, more preferably 0.5 to 5.0 mm.
If the contact length is less than 0.5 mm, there is too little contact between the laminated films 30 and 31 on the front and back surfaces at the pressing portion 28 position, the contact force is insufficient, and the cassette type liquid material filling composite container C When they fall over, they will be separated easily, and the leak-proof function cannot be exhibited. On the other hand, if it exceeds 10.0 mm, the adhesion between the laminated films 30 and 31 on the front and back becomes strong. This is because free dispensing is difficult because, for example, it is necessary to strongly press the barrel portion of the cassette-type liquid material filling composite container C when discharging the liquid or viscous packaged object.

  As shown in FIG. 2, the intermediate tube 9 has a substantially flat plate-like upper end portion and a substantially flat hexagonal section through a mountain fold line 9b. In addition, the intermediate | middle cylinder 9 has the notch part 9c in the upper part, and is comprised so that the extraction | pouring nozzle 1 may protrude from this notch part 9c. As shown in the developed view of FIG. 5, the notch 9c is provided with a protective piece 12 to protect the dispensing nozzle 1 from the front and back until the start of use, and to prevent the dispensing nozzle 1 from being bent or damaged. It may be. The intermediate tube 9 can be formed of paper, plastic, or the like, and any material can be used as long as the packaging body 4 can be given regularity.

  At the lower end portion of the intermediate cylinder 9, it is preferable to provide 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 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 exert an effect of suppressing a decrease in the self-supporting property of the cassette intermediate container 10. .

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

In addition, it is preferable that the projecting piece 14 and the projecting piece 15 are respectively provided with mountain fold lines 14a and 15a and valley fold lines 14b and 15b made of cuts or the like. According to this, as described above, when the projecting piece 14 and the projecting piece 15 are folded inside the intermediate cylinder 9 along the folding line 26, the mountain folding line 14a, 15a and the valley folding line 14b, 15b are naturally along. Even if the projecting piece 14 and the projecting piece 15 are folded, and the bottom plate 11 may fall out due to the weight of the package 4 or an impact at the time of handling, the projecting pieces 14 and 15 are removed from the table surface. The bottom plate 11 can be easily folded inside the intermediate cylinder 9 simply by pressing it against the inner cylinder 9.
The intermediate cylinder 9 can be formed by integral molding by blow molding or the like, in addition to the sheet material 13 as shown in FIG.

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 torsional section that gradually swells from the pointed head 16a and the tail end 16b is in the form of an arc-shaped water drop or tear drop, The cassette intermediate container 10 is fitted so that the pouring nozzle 1 of the cassette intermediate container 10 is positioned on the pointed head 16a side. Thereby, in use, the arc-shaped portion on the tail end portion 16b side of the outer container 16 will be gripped, and it will fit into the fingers, allowing the packaged item to be poured out while gripping firmly.

  Since the outer container 16 and the cassette intermediate container 10 have different cross-sectional shapes at the barrel position, when the cassette intermediate container 10 is fitted in the outer container 16 as shown in FIG. A space 17 is formed between the outer container 16 and the outer container 16. For this reason, even if the outer container 16 is gripped without any effort, the space 17 functions as a buffer layer, and the pressing force is not directly applied to the cassette intermediate container 10. 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 it can be recycled and used a plurality of times by replacing the cassette intermediate container 10 to be fitted inside. It is preferable to do.

  As shown by a virtual line (two-dot chain line) in FIG. 1A, the outer container 16 has 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 intermediate container 10. A cap 27 that can be swung may be provided, and the cap 27 can prevent the dispensing nozzle 1 from being exposed to the outside during storage of the cassette type liquid material filling composite container C. In addition, there is no possibility that dust, bacteria, or the like will adhere to the pouring nozzle 1, and the pouring nozzle 1 and the object to be packaged in the bag can be prevented from being damaged.

  As shown in FIG. 1B, the outer container 16 may be formed to have an approximately the same width up to the upper portion in addition to a shape that gradually becomes narrower toward the upper portion. In addition, as shown in the end view (FIG. 6) in the AA position of FIG. 1A, the outer container 16 is provided with a pair of clamping claws 32 on the inner surface of the upper end of the outer container 16, and the pair of clamping claws. When the upper end (plate portion) of the intermediate cylinder 9 of the cassette intermediate container 10 is fitted and held between 32, the cassette intermediate container 10 can be easily fixed in the outer container 16. , It is possible to prevent the cassette intermediate container 10 from slipping out or falling off. The clamping claws 32 have a flat clamping surface as shown in FIG. 6 (a), and also when the clamping surface has serrations and other irregularities as shown in FIG. 6 (b). Can effectively suppress slipping of the upper end portion of the intermediate cylinder 9 sandwiched.

  Further, for example, as shown in FIG. 1A, a hooking hole 18 is provided in the intermediate tube 9 of the cassette intermediate container 10, while a hooking piece 19 is provided in the outer container 16, and the cassette intermediate container 10 is fitted in the outer container 16. When the engaging hole 18 and the engaging piece 19 are fitted to each other when the cassette is inserted, the cassette intermediate container 10 can be effectively prevented from slipping or falling off from the outer container 16. The engaging hole 18 and the engaging piece 19 can also be provided on opposite members, and the formation positions thereof are not particularly limited.

  In another embodiment of the outer container 16 in FIG. 7, three slits 33 are provided on the side surface of the tail end side 16 b at intervals in the vertical direction. A plurality of slits 33 are preferably provided on at least one of the side surface of the outer container 16 on the side of the cusp 16a and the side of the tail end 16b. The slit 33 makes it easy to fold the side of the outer container 16, and even when the outer container 16 is made of a material having rigidity, the outer container 16 can be crushed until it becomes flat. The object to be packaged in the package 4 can be pushed out to the end by pressing with a finger to the part, and the remaining amount can be reduced.

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

  In addition, in the case where the front and rear central portions of the outer container 16 are formed into a thick part 16c in a band shape, when the body part of the outer container 16 is sandwiched in use, the clamping force is directly increased by the rigidity of the thick part 16c. While it is not transmitted to the cassette intermediate container 10 and there is no possibility that the packaged item may unexpectedly jump out, when the thick-walled part 16c is pressed with a finger when discharging the packaged object, not only the pressed part but also the band-shaped thick-walled part Since the entire 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 engagement hooks 21 provided on the peripheral edge thereof into engagement holes (not shown) provided in the outer container 16. Here, each of the engaging protrusion 21 and the engaging hole can be provided on the opposite member. In addition, in the place shown in FIG. 8, 22 and 23 show a reinforcement rib.

In the cassette type liquid material filling composite container C of the present invention, as shown in FIG. 2A, the remaining amount of the packaged object in the package 4 is visually confirmed in the intermediate tube 9 of the cassette intermediate container 10. 1 is provided in one or more locations, and the outer container 16 is provided with a plurality of slits 25 extending in the lateral direction as shown in FIG. The remaining amount of the packaged object can be easily visually recognized through the 25.
The slit 25 also has a function of buffering the pressing force when the outer container 16 is pressed with a finger and suppressing other parts from being deformed or damaged.

  The cassette type liquid material filling composite container of the present invention can be widely used as a refillable container for filling and packaging liquid or viscous liquid materials such as beverages, pharmaceuticals, chemicals and cosmetics.
