Description

  The present invention relates to an outer container for a business-use liquid-filled package suitable for repeatedly dispensing a liquid that may contain a large-volume viscous material exceeding 1 liter.

As a conventional technique in which a handle portion is provided on an outer container as a grip portion, there is one disclosed in Patent Document 1 previously proposed by the applicant.
The present invention relates to an assembly container for a non-self-supporting liquid-filled package, and in particular, a liquid pouring nozzle having a non-return function, that is, a film-like non-return nozzle formed using a soft laminated film. The present invention relates to a self-supporting assembly container for storing a non-self-supporting liquid-filled packaging body having, and suspending and holding it so as to be attached and detached.

Moreover, this patent document 1 describes the following points. A flexible packaging bag that is not self-supporting becomes a liquid-filled packaging body in an expanded state by filling and packaging the packaged material in the bag, preferably under evacuation (filling with liquid seal). Then, the packaged material filled and packaged in the liquid-filled package body is opened by tearing and removing the tip portion of the nozzle from, for example, a finger from the notch of the fusion portion on the upper side of the check pouring nozzle, The liquid-filled package can be poured out by tilting it with an outer container that preferably stores and holds it. As a result, the tip spout of the nozzle of the liquid-filled package is sufficiently opened on the front and back sides due to the water head pressure of the package in the bag (a gap is formed between the overlapping laminated films). Going out.
When a packaged item is poured out in this way, the packaging bag body made of a soft laminated film, that is, the flexible packaging bag itself, sucks outside air from the spout of the liquid dispensing nozzle as the packaged item is poured out. Instead, it contracts or collapses by an amount corresponding to the dispensed volume and comes into close contact.

  After a required amount of the package is poured out by tilting the liquid filling package, the pouring is stopped when the liquid filling package is returned to the original standing posture. Due to the stopping of the pouring, the inner surfaces of the pouring passages of the pouring nozzle wetted by the packaged object are brought into close contact with each other due to the liquid film formed by the packaged object. That is, at the same time as the pouring is stopped, the pouring spout at the tip of the pouring nozzle is sealed over the width direction of the front and back of the liquid pouring nozzle, in other words, the entire vertical direction, and the outside air enters the liquid filling package. Is reliably prevented (reverse action).

  Therefore, in the liquid-filled package including this non-return dispensing nozzle, the packaged items in the bag are prevented from contacting the outside air during and after the dispensing as well as before the dispensing. Oxidation and fouling of the packaged items in the bag can be prevented.

  By the way, the non-return action of the film-like non-return nozzle having such a non-return function, or the film on the front and back of the liquid pouring nozzle, which should be called a film valve, is caused by the rising and returning of the liquid-filled package. In addition to the discharge nozzle being released from the action of water head pressure and returning to the shape at the time of manufacture, when the packaged item in the dispensing nozzle returns to the inside of the packaging bag body, it becomes wet with the packaged item. This occurs when the inner surfaces of the front and back films are brought into close contact by the capillary action of the package. This is the same for the packaging bag body, which is exposed to a reduced-pressure atmosphere due to crushing deformation or the like accompanying pouring, and the inner surfaces of the laminated films constituting the packaging bag body are mutually adsorbed. As a result, a non-return function that prevents the intake and entry of outside air is produced. In other words, the adhesion between the films of the pouring nozzle is in combination with the capillarity described above, and the packaging bag body that is shrunk or crushed and deformed with the pouring of the package from the liquid-filled package is inherent to it. It becomes more certain when the inside is made to have a reduced pressure tendency based on the elastic restoring force.

  Thus, in this case, the tip spout of the liquid filling package can be automatically sealed in close contact with the upright return of the liquid-filled package without any special operation on the dispensing nozzle, and the reverse of the dispensing nozzle is excellent. The stopping function can be exhibited. In short, this liquid pouring nozzle is composed of two overlapping or half-folded soft laminated films fused together at the outer peripheral edge except for the base end of the nozzle. When a packaged object is formed by tilting the inside of the packaging bag body and pouring the packaged article, the packaged article passes through the dispensing path, and the inner surface of the dispensing path is formed. Becomes a wet state, and the inner surfaces of the dispensing passages become a film-like check valve that generates a check function that prevents the intrusion of outside air by the mutual contact action caused by the remaining articles to be packaged.

  Such a pouring nozzle with a non-return function is composed of a thermoplastic, uniaxially or biaxially stretched base film layer and a sealant layer laminated directly or indirectly, for example, by extrusion lamination or dry lamination. Laminate by lamination or co-extrusion, and laminate films on each side of the front and back, for example, two laminated films on the front and back, or one laminated film folded back on the front and back at the center, one sealant layer facing each other In the peripheral portion excluding the base end side, they are fused together to form a substantially wedge shape or the like. Note that the fusing temperature of each sealant layer laminated with the base film layer sandwiched between them can be varied by changing the material, changing the extrusion laminating conditions of each sealant layer of the same material, etc. It is preferable that the melting point of the sealant layer on the inner surface be at least 5 ° C. higher than the melting point of the sealant layer on the nozzle outer surface.

  In addition, this pouring nozzle imparts high water vapor impermeability, gas barrier properties, etc., and facilitates smooth and easy removal of the tip of the pouring nozzle with a finger, and also allows tear creases such as fuzzing. The non-return function can be more fully exhibited by making it sufficiently smooth. Therefore, the base film layer is a uniaxial or biaxially stretched polyethylene terephthalate layer, an ethylene vinyl alcohol copolymer layer, a nylon layer, a polyester layer, a polypropylene layer, or the like, and a required vapor deposition layer is provided on any of them. It is preferable to form by things. As the sealant layer, various non-stretched PE layers, PP layers, metallocene-catalyzed polyethylene layers and other olefin resin layers, ethylene vinyl acetate copolymer layers, ethylene ethyl acrylate copolymer layers, ionomer layers, ethylene It is preferably formed by a vinyl acetate copolymer layer, an ethylene vinyl alcohol copolymer layer, or the like.

  Such a liquid-filled package body in which a packaged product is sealed and filled in a flexible packaging bag having a pouring nozzle with a non-return function, and the packaging bag body is composed of a soft plastic laminated film itself. Since there is no self-supporting property or formability, it is necessary to store the liquid-filled package in a holding container. Therefore, in the present invention, such a liquid-filled package is housed, suspended and held, and the body to be packaged in the liquid-filled package is pressurized as necessary. It is also described that an assembling and reusable container having a dispenser function of discharging from the dispensing nozzle under flow rate adjustment has been studied.

  In this device, the advantage of the liquid pouring nozzle with a non-return function as described in Patent Document 1 is added, and the outer container is further improved. It is used for business purposes, has excellent durability, and is easy to use. Well, it can withstand long-term use and dispense the required amount by simply replacing non-self-supporting packaging bags filled with liquids that may be viscous, such as oil and dressings. It is in providing the outer container which can be performed repeatedly.

  The present invention has been developed through extensive research and studies to achieve the above object, and the gist of the present invention is for packaging of a laminated structure including at least a base film layer and a sealant layer. The inner surface of the flexible packaging bag body, which is formed by fusion bonding the sealant layer of the film, consists of a thin, flat laminated film with sealant layers on both the front and back sides. The outer surface of the base end of the non-return pouring nozzle having a self-sealing function is formed by fusion bonding around the pouring passage of the package except for the base end side, and the non-return pouring is performed. Stores and holds a liquid-filled package that has no fixed form or self-supporting property in which a liquid package is filled and packed in a soft packaging bag that is provided with a nozzle protruding from the top or side of the flexible packaging bag body. The An outer container having a rigidity higher than that of a packaging bag that imparts formability and self-supporting property to a package-filled package, the outer container including a cylindrical main body with a bottom wall provided with a grip portion, and a liquid-filled package Is suspended and supported in the cylindrical main body, and a lid that overlaps the top surface of the cylindrical main body, and the lid is provided with two members having a substantially semicircular planar shape at one end. The other is supported so as to be capable of opening and closing with respect to each other via the hinge part, and the abutting surface of the two members is a sandwiching part that sandwiches the fusion part at the upper end of the liquid filling package. Propose a characteristic outer container.

In the present invention,

When the fitting part is engaged by engagement with the protrusion on the outer surface of the main body, it is almost semicircular regardless of whether the fitting part of the male or female is engaged. Unintentional release of the two-piece lid, and hence suspension of the liquid-filled package, can be sufficiently prevented.

  Further, according to this outer container, the liquid filling container is turned upside down by the support provided on the lid regardless of the contents of the liquid filling package stored in the cylindrical main body. In addition, it is possible to effectively prevent the displacement of the non-returning nozzle, but the anti-swaying part that prevents the nozzle from swinging is used for the purpose of the packaged item in the bag. Therefore, it is possible to more reliably dispense into the position.

  In addition, when a cushioning material that directly contacts the top surface of the cylindrical body is provided on the lid, dimensional errors such as manufacturing errors and assembly errors of the cylindrical body and lid are effective with the cushioning material. Can be absorbed into.

  And when the planar contour shape of the lid and the cylindrical body is an oval or an ellipse, the upper end fusion part of the liquid filling packaging body is sandwiched, and a sandwiching part that is suspended in the cylindrical body, The check dispensing nozzle is prevented from swinging, and a sufficient space for forming the steady rest portion for pouring the packaged items in the bag to the intended dispensing position is secured. The function as expected can be fully exhibited.

Embodiments of the present invention will be described below based on the drawings.
A liquid-filled package 1 shown in FIG. 1 includes a flexible packaging bag body 3 formed by fusion-bonding a sealant layer of a soft packaging film having a laminated structure at a peripheral portion, a side or upper side thereof, and a side in the figure. In a soft packaging bag 4 having a self-sealing function that is provided so as to protrude and having a flat non-return dispensing nozzle 2 that prevents entry of outside air into the packaging body 1, food and drink, seasonings It is formed by filling and packaging a liquid package that may contain a material, cosmetics, pharmaceuticals, or other viscous materials or viscous materials, and this liquid-filled package 1 has both formability and self-supporting properties. There is nothing.

Here, the packaging bag main body 3 shown in the figure is a heat treatment as shown in the drawing with a hatched portion in the periphery of the packaging film having a laminated structure of two layers or three or more layers having a sealant layer on the inner surface. The three sides are formed by fusion bonding, except for the liquid filling port, by a seal, impulse seal, high-frequency welder seal, ultrasonic seal or the like. In addition, the thin and flat non-return dispensing nozzle 2 having a self-sealing function provided so as to protrude laterally from the upper end portion in the figure of the packaging bag body 3 has a sealant layer on both the inner and outer surfaces. It has a laminated structure of three or more layers, and is preferably a softer laminated film than a packaging film, for example, in the peripheral part around the dispensing passage 5 of the package in the bag formed in the center part of two sheets, Except for the base end side, this is also shown by hatching in the figure, and it is a sealant layer on the inner surface and is fusion-bonded by the same sealing method as described above.
The non-return dispensing nozzle 2 is formed by fusing and bonding a single soft laminated film in a half-folded manner in the central portion and partitioning the dispensing passage 5 in the central portion. You can also

  Therefore, such fusion bonding to the check pouring nozzle 2 and the packaging bag body 3 is performed by applying the sealant layer on the outer surface of the check pouring nozzle 2 to the sealant layer on the inner surface of the packaging bag body 3. Thus, the pouring passage 5 in the central area communicates with the filling space 6 of the liquid packaged article in the packaging bag body 3.

  By the way, the inside of the base end portion of the check pouring nozzle 2 at the time of such fusion bonding of the sealant layer on the outer surface of the base end portion of the check pouring nozzle 2 to the inner surface sealant layer of the packaging bag body 3. The fusion of the surface sealant layers is, for example, by relatively increasing the melting point of the inner surface sealant layer of the check pouring nozzle 2 relative to the fusion of the outer surface sealant layer of the check pouring nozzle 2, It can be effectively prevented.

  On the other hand, in order to prevent permanent deformation of the dispensing passage 5 of the non-return dispensing nozzle 2 and, consequently, deterioration of the self-sealing function of the non-return dispensing nozzle 2, the dispensing passage 5 of the non-return dispensing nozzle 2 is used. And a temporary fusion part having a bonding strength of less than half of a complete fusion bonding part that reliably blocks the communication between the packaging bag body 3 and the liquid filling space 6. It is also possible to form on the inner surface of the proximal end portion.

Here, the filling and packaging of the liquid package in such a soft packaging bag 4 provided with the check pouring nozzle 2 is performed by, for example, continuously supplying the package to be packaged. As a contaminant, the soft packaging bag 4 can be sealed by submerged seal filling, etc., which performs a horizontal seal, and in this way, a predetermined amount of packaged material is filled and packaged. Such a four-side seal liquid filling package 1 is formed.
In FIG. 1, the liquid-filled package 1 is shown in an upright position. However, since the packaging film 1 constituting the packaging bag 4 is soft, in reality, the formability is also self-supporting. It does not have sex.

  The pouring of the liquid package from the liquid filling package 1 and the stopping of the pouring are performed in the same manner as in the prior art, and during the pouring of the liquid package and The intrusion of outside air into the packaging body 1 after the completion of the dispensing is surely based on the collapse deformation of the filling packaging body 1 and the self-sealing function of the check dispensing nozzle 2 as described above. Will be blocked.

  Then, such a liquid package 1 is stored and held in an upright position to give the filling package 1 regularity and self-supporting property. For example, a gripping portion 7 such as a handle is provided on the side portion or the top portion.
