JP6399495B2 - Holding container for liquid filling packaging - Google Patents

Description

  The present invention relates to a container for holding a liquid-filled package, and in particular, liquids, viscous products, and other liquid coatings that may contain foods and drinks, pharmaceuticals, cosmetics, various liquids, powders, granules, etc. The present invention relates to a holding container used for filling and packaging a package, storing and holding a soft liquid-filled package having no fixed form and self-supporting property, and providing it with self-supporting property.

As a bag made of a soft plastic film for filling and packaging a liquid article to be packaged, that is, as a packaging bag, there is a packaging bag having a non-return type film-like dispensing nozzle. It is disclosed.
This non-return type pouring nozzle is formed by folding one plastic film in half or overlapping two plastic films. When pouring out the liquid package in the bag, It has a function of automatically preventing air (outside air) corresponding to the volume of the dispensed amount from entering the packaging bag.

  This pouring nozzle prevents the outside air from flowing back into the bag due to the shrinkage or crushing deformation of the packaging bag body itself when pouring out the liquid package filled in the bag. At the same time as stopping the dispensing of the packaged contents (contents), it automatically closes the dispensing passage in the dispensing nozzle by wetting with the liquid packaged object, and reverses the intrusion of outside air into the packaging bag It has the feature of exhibiting a stop function (self-seal check function).

  Accordingly, a packaging body in which a liquid package is filled and packaged in a packaging bag having a dispensing nozzle exhibiting the above-described check function, before dispensing the liquid material, It is characterized in that outside air can be prevented from entering the packaging bag body both during and after dispensing.

  In the packaging bag described in the above-mentioned patent documents 1 and 2, when the packaging bag is returned from the tilting posture to the standing posture when stopping the dispensing of the liquid package as described above, the dispensing nozzle is dispensed. The inner surfaces of the passages are in close contact with each other due to wetting by the liquid package, and are automatically sealed, but when this pouring nozzle is closed, the liquid package near the tip opening of the pouring nozzle is , It will be divided into one that flows back into the packaging bag body through the pouring passage and one that is pushed out from the tip opening. At that time, the liquid package that has been pushed out from the opening at the front end does not sufficiently run out (drop), flows and remains attached to the opening, or falls from the lower end of the opening, There was a risk of fouling the packaging bag and its surroundings.

  Therefore, in order to solve the above-mentioned problems, the applicant, in Patent Document 3, provided a film-like pouring nozzle so as to protrude obliquely upward from the top of the packaging bag body. Smooth dispensing and finer dispensing volume without obstructing the dispensing characteristics at the opening of the dispensing passage when the dispensing of the packaged goods is stopped with the self-seal check function of the nozzle intact. We have proposed a packaging bag that can be adjusted, has good liquid drainage, and prevents dripping.

  Since the packaging bag of the above-mentioned Patent Document 3 is made of a soft plastic film, the packaging body in a state of being filled and packaged with a liquid package has neither a fixed form nor a self-supporting property. In order to hold it in the form of use, a holding container for storing it and imparting independence is required.

  Therefore, the present invention not only can give the package body a fixed form and self-supporting property, but also allows the liquid package to be mixed by a shake or the like. Even in such a case, it is an object of the present invention to provide a holding container for a liquid-filled packaging body that can effectively prevent leakage of the filled liquid package from a dispensing nozzle.

A holding container for a liquid filling package according to the present invention is a packaging in which a film-like dispensing nozzle having a self-seal check function is projected obliquely upward from the top of a soft packaging bag body made of a laminated film. A holding container for storing and holding a package formed by filling and packaging a liquid package in a bag,

  The holding container for a liquid filling package of the present invention (hereinafter simply referred to as “holding container”) is a composite of paper, plastic, limestone (calcium carbonate amount exceeding 50%) and plastic having inherent rigidity and elasticity. It is made of materials, metals, ceramics, porcelain, etc. Even if any of them, the soft packaging body (liquid-filled packaging body) that is not self-supporting is held in a certain form of use under its inherent rigidity, and it stands up. It is possible to impart the formality and the independence necessary to make it happen. In particular, when paper, plastic, limestone / plastic composite material, or metal is used, due to its inherent elasticity, the intermediate portion of the holding container can be pressed under the reduced amount of liquid packaging remaining in the package. The liquid package can be squeezed out effectively based on the large elastic deformation of the holding container, particularly the lower end portion. In addition, in this case, the lower end portion of the holding container can be quickly elastically restored to the original shape without fear of the holding container falling down.

  Further, the holding container of the present invention is integrated with the holding container on the side of the upper portion of the holding container where the pouring nozzles of the packaged body are located, or separately from the holding container so as to sandwich the pouring nozzles from both sides. A nozzle pincher formed as a nozzle pincher (Nozzle Pincher) was provided, and the nozzle pincher was composed of a horizontal support portion that sandwiched the upper end portion of the dispensing nozzle and a vertical clamping portion that sandwiched across the dispensing passage of the dispensing nozzle There is a feature. As a result, the pouring nozzle is supported (supported) from the upper end portion and both side surfaces, and the bending of the pouring nozzle is suppressed not only during the pouring of the liquid package, but also before and after the pouring. In particular, it is possible to prevent the pouring nozzle from swinging up, down, left and right during the pouring of the liquid package, so that the discharge directionality (directivity) of the liquid package can be improved. .

  Further, in the present invention, according to the nozzle pincher, by providing an opening / closing lid that allows the nozzle pincher to be tightened and released so as to open and close the dispensing passage, the opening / closing lid allows the vertical pinching portion of the nozzle pincher to be provided. Thus, the dispensing passage of the dispensing nozzle can be easily closed and opened. As a result, if the opening / closing lid is in a closed posture, the liquid package can be sufficiently mixed by a shake or the like even after the dispensing nozzle has been opened, and the holding container has been overlaid, etc. However, there is no possibility that the liquid package will leak from the tip of the pouring nozzle.

  Further, since the opening / closing lid is rotatably supported on the upper portion of the holding container, the opening / closing lid can be easily opened and opened and opened / closed by one-handed operation. Can do.

  Furthermore, when the nozzle pincher has an inverted V-shaped cross-section that forms a C-shape when the tightening by the opening / closing lid is released, the dispensing nozzle is not affected at all by the nozzle pincher and is smooth. As the liquid packaged item remains in the pouring passage of the pouring nozzle, the nozzle pincher can be gradually pinched from the top to the bottom with the opening and closing lid and tightened. In addition, there is no risk that the liquid package will be scattered and the surroundings will be soiled by tightening the open / close lid, and the discharge amount of the liquid package will be adjusted by adjusting the pressing force of the dispensing nozzle according to the tightening position of the open / close lid You can also

  Further, when one side end of the horizontal support portion of the nozzle pincher is positioned in the vicinity of the planned opening position of the tip end portion of the pouring nozzle, the above described effect of suppressing the bending of the pouring nozzle and improving the directivity and liquidity The leakage prevention effect of the packaged item can be further enhanced, and when opening the tip portion of the pouring nozzle, the horizontal support portion can be opened while being pressed with fingers, so that the opening operation is easy, It can be torn and opened accurately in the specified direction. Therefore, the occurrence of dripping can be suppressed.

  Further, the vertical pinching portion of the nozzle pincher is arranged at an extended position of the inclined portion including a tear opening and an inclined portion that protrudes obliquely upward from the upper end edge of the packaging bag body on the proximal end position side of the dispensing nozzle. When the free end portion is positioned in the vicinity of the boundary between the upper end edge of the packaging bag body and the horizontal portion, the pouring passage is firmly closed by the vertical clamping portion, Leakage can be effectively prevented, and even if the holding container falls down during storage or handling, it is possible to prevent the in-bag package from entering the horizontal portion of the dispensing nozzle. The horizontal portion is not deformed, and the self-seal check function of the dispensing nozzle is not hindered.

  Furthermore, in the present invention, a concave portion is provided at the upper end of the flat upper portion of the holding container on the side where the pouring nozzle is located, and the end portion of the horizontal support portion of the nozzle pincher is fitted and attached to the concave portion.

Embodiments of the present invention will be described below based on the drawings.
The packaging bag 1 shown in FIG. 1 applicable to the holding container according to the present invention includes a flexible packaging bag body 2 and a film-like dispensing nozzle 3 having a self-seal check function communicating with the packaging bag body 2. Be prepared. The pouring nozzle 3 is in a posture that protrudes obliquely upward from the top of the packaging bag body 2, and the outermost sealant layer at the base end portion of the pouring nozzle 3 is used as the sealant layer on the inner surface of the packaging bag body 2. For example, it is integrated with the packaging bag body 2 by fusion bonding.

  Here, the pouring nozzle 3 includes, for example, a uniaxial or biaxially stretched PET base film layer or NY base film layer having a thickness of 5 to 40 μm and each sealant layer laminated with the stretched base film layer interposed therebetween, for example, A flat and thin laminated film with a non-stretched PE layer or PP layer with a thickness of 5 to 80 μm, mostly in a three-layer structure, that is, two thin walls with the same contour shape, both front and back Laminate film or one thin laminate film that is folded back and forth at the center, etc., is fused and bonded to each other at the peripheral edge except the base end in the mutually facing posture of one sealant layer, for example by heat sealing It can be configured by dividing the extraction passage 4 in the central portion by equalization. In the illustrated dispensing nozzle 3, the distal end portion 5 of the nozzle 3 is cut off by, for example, tearing removal at the position of the V-shaped bent portion 6 to form the distal opening 7 in the dispensing passage 4. be able to.

  In such a packaging bag 1, as described above, the tip portion 5 of the pouring nozzle 3 is torn and removed to pour the tip into the pouring passage 4 of the pouring nozzle 3 when pouring out the packaged items in the bag. In a state in which the opening 7 is formed, the packaging bag 1 is tilted, the inner surface of the dispensing passage 4 is largely separated by the water head pressure of the article to be packaged, and the tip opening 7 is opened, so that the liquid packaging It is possible to dispense according to the requirements of goods. At this time, the packaging bag body 2 contracts or collapses in accordance with the volume of the packaged material, so that the packaging bag 1 can be poured out without taking in outside air.

  On the other hand, when stopping the dispensing of the liquid package, the packaging bag 1 is raised and returned. At this time, the dispensing passage 4 is released from the head pressure or the like of the article to be packaged, and returns to its original shape under the generation of negative pressure due to the return flow of the liquid article into the packaging bag body 2. In addition, the inner surface wetted by the liquid packaged object by the thin film of the packaged object is adsorbed under negative pressure with the assistance of the reduced-pressure atmosphere in the packaging bag body 2 to automatically set the dispensing passage 4. Since it can be hermetically sealed, the dispensing nozzle 3 can automatically exhibit a self-seal check function that prevents the outside air from entering the packaging bag 1.

  Therefore, this packaging bag 1 is sufficiently protected from contact with the outside air both during and after the liquid packaging as well as before the liquid packaging. Oxidation, fouling, etc. are effectively prevented.

  In the packaging bag 1 including the dispensing nozzle 3 having such a self-seal check function, the dispensing nozzle 3 has a substantially curved shape as described above, and is projected obliquely upward from the top of the packaging bag body 2. It is provided in a posture. As a result, the position of the tip opening 7 of the dispensing nozzle 3 is higher than the tip opening position of the packaging bag protruding from the side of the conventional packaging bag body. In order to pour out, it is necessary to tilt the packaging bag 1 more than before.

  Therefore, in the packaging bag 1 which concerns on this invention, the force of the direction along the end surface of the front-end | tip opening 7 of the extraction | pouring nozzle 3, ie, the direction in which a liquid to-be-packaged material flows along the lower end of the front-end | tip opening 7, is conventionally. Therefore, the liquid packaged material that has been poured out is dropped from the tip opening 7 of the nozzle by gravity and dropped without dropping through the tip opening 7. Therefore, according to this packaging bag 1, the liquid breakage is good, and the liquid package does not remain attached to the tip opening 7 and does not cause dripping.

  In addition, when stopping the dispensing of the packaged item, the tilting angle (starting angle) for pouring the liquid packaged item is almost the same as the tilting angle (ending angle) when stopping the dispensing. Therefore, in the packaging bag 1 used in the present invention, when the packaging bag 1 is raised and returned, the liquid packaged object pushed out from the vicinity of the tip opening 7 does not travel down the tip opening 7. As it is, it is detached from the end face of the tip opening 7 and dropped. Therefore, the liquid package does not remain attached to the tip opening 7 and the dripping can be effectively suppressed.

  The pouring nozzle 3 has a horizontal portion 4b parallel to the upper end edge 2a of the packaging bag body 2 on the leading end side (the free end portion side of the pouring nozzle 3) of the extending portion of the inclined portion 4a of the pouring passage 4. The article to be packaged that has flowed into the inclined portion 4a on the nozzle base end portion 3a side of the dispensing passage 4 due to the inclination of the packaging bag 1 to the horizontal portion 4b that is narrower and parallel to the inclined portion 4a. , The flow is rectified and becomes a laminar flow toward the tip opening 7. For this reason, the liquid package does not scatter from the tip opening 7 of the pouring nozzle 3 in an unexpected direction, and is excellent in liquid drainage. In particular, the liquid package can be adjusted by adjusting the tilt angle of the packaging bag. The discharge amount of the package can be adjusted. The discharge flow of the liquid package is rectified as the horizontal portion 4b is longer, and the liquid package can be discharged accurately in the intended direction.

  FIG. 2 is a side view of a holding container 11 for storing and holding a package formed by filling and packaging a liquid package in the packaging bag 1 having the above-described configuration, and imparting formability and self-supporting property thereto. is there. The holding container 11 can be formed of paper, plastic, limestone (calcium carbonate amount more than 50%) and plastic composite material, metal, ceramics, porcelain, etc., and has a cylindrical shape at the lower part 12b and a flat shape at the upper part 12a. The container body 12 has a shape (flat upper portion 12c), and a nozzle pincher 13 and an opening / closing lid 14 provided on the flat upper portion 12c on the side where the pouring nozzle 3 of the stored package is located.

The container body 12 has a notch 12d on the side of the flat upper portion 12c where the pouring nozzle 3 is located, and is configured such that the pouring nozzle 3 of the package housed from the notch 12d protrudes (exposes). Has been.
In the holding container 11 of the present invention, a nozzle pincher 13 is provided so as to sandwich the pouring nozzle 3 protruding from the notch 12d from both sides, and the nozzle pincher 13 is made of, for example, plastic so as to cover from the outside. It is characterized in that a pivotable opening / closing lid 14 is provided by hinge connection or the like.

The nozzle pincher 13 is formed separately from the container body 12 as shown in FIG. 2, and is attached to the container body 12 using pins or the like, and is formed integrally with the container body 12 by blow molding or injection molding. You can also
The following describes an embodiment in which the nozzle pincher 13 is formed separately from the container body 12 as a representative example.

  The nozzle pincher 13 of FIG. 2 has a pair of front and back horizontal support portions 13a sandwiching the upper end portion of the dispensing nozzle 3 as shown in FIG. 3A and the front and back sandwiching across the dispensing passage 4 of the dispensing nozzle 3. For example, two sheets made of plastic can be overlapped on the front and back, or one sheet can be folded into two at the center.

  In addition, it is preferable to arrange | position the nozzle pincher 13 so that the edge part by the side of the front-end | tip of the extraction nozzle 3 of the horizontal support part 13a may be located in the vicinity of the bending part 6 which is an opening planned position of the extraction nozzle 3. . Accordingly, the bending of the pouring nozzle 3 can be effectively suppressed, and while the pouring nozzle 3 can be held by the horizontal support portion 13a, the bent portion 6 can be torn and opened, so that hygiene It is possible to tear and open easily and accurately, and to effectively prevent dripping.

  Further, the vertical clamping portion 13b includes an inclined portion 4a that protrudes obliquely upward from the upper end edge 2a of the packaging bag body 2 on the base end portion 3a side of the pouring nozzle 3, and an extension of the inclined portion 4a including the tear opening. It is preferable to locate in the vicinity of the boundary with the horizontal portion 4b on the free end side which is the position. In this case, as will be described later, when the nozzle pincher 13 is tightened by the opening / closing lid 14, not only can the dispensing passage 4 be firmly clamped by the vertical clamping portion 13b to be completely sealed, but also the holding container Even when stored in a state in which 11 is tilted, the vertical sandwiching portion 13b can prevent the liquid package from entering the horizontal portion 4b of the dispensing nozzle 3. Therefore, the inner surface of the dispensing passage 4 of the dispensing nozzle 3 can always be kept flat without being permanently deformed in the direction in which the horizontal portion 4b swells. There is no risk of the check function being disturbed.

  In addition, the nozzle pincher 13 has the hinge hole 15 in the anti-vertical clamping part 13b side of the horizontal support part 13a, as shown to Fig.3 (a). The hinge hole 15 is formed by an opening or a recess and functions as a support portion for the opening / closing lid 14. When the hinge hole 15 is an open hole, the nozzle pincher 13 is disposed so as to sandwich both side surfaces of the flat upper portion 12c of the container body 12, and is provided in the hinge hole 15 (open hole) and the flat upper portion 12c. The nozzle pincher 13 can be fixed to the container body 12 by positioning so that the hinge hole 23 (FIG. 5) overlaps and inserting the pin 17 and the like into the hinge hole 15 and the hinge hole 23.

  The nozzle pincher 13 can also be formed by bending one sheet as shown in FIG. 4A inward at the center. In the nozzle pincher 13, for example, a protrusion 18 is provided on the right half side of the sheet and an opening 19 is provided on the left half side. The protrusion 18 and the opening 19 are connected to the hinge hole of the flat upper portion 12 c of the container body 12. By fitting at the 23 position, the flat upper portion 12c can be fixed without using a pin or the like. Further, in this nozzle pincher 13, as shown in the end view of FIG. 4B, a concave portion 18a is provided on the surface of the projection 18, and a concave portion 18b is provided on the side surface on the opposite projection 18 side. When attached to 12c, the recesses 18a, 18b can function as the hinge hole 15 of the opening / closing lid 14.

Next, as shown in the perspective view of FIG. 5, the opening / closing lid 14 has a pair of plate-like wall surfaces 14a, and the nozzle pincher 13, the flat upper portion 12c, and the dispensing nozzle 3 are placed between the wall surfaces 14a. A groove portion 14b for fitting and storing is provided.
The groove width of the groove portion 14b constituted by the pair of wall surfaces 14a is such that when the nozzle pincher 13, the flat upper portion 12c and the dispensing nozzle 3 are fitted, the nozzle pincher 13 is pressed from both sides by the pair of wall surfaces 14; As a result, the dispensing nozzle 3 is sufficiently tightened through the vertical clamping portion 13b so that the dispensing passage 4 can be completely sealed.

In FIG. 5, the opening / closing lid 14 is pivotally connected via a pin 17 for fixing the nozzle pincher 13 to the flat upper portion 12 c, but is not limited thereto, for example, Protrusions are provided on the inside of the pair of wall surfaces 14a of the opening / closing lid 14, and the protrusions are rotatably supported by being fitted into the recesses 18a and 18b (hinge holes 15) of the nozzle pincher 13 of FIG. Can be made.
The opening / closing lid 14 only needs to have a function of exposing and storing the pouring nozzle 3 and tightening and releasing the pouring nozzle 3 through the nozzle pincher 13. Various holding tools such as a rail groove or the like provided on the upper portion 12c to be slidable can also be used.

  According to the holding container 11 having the above-described configuration, the pouring nozzle 3 of the stored package is supported by the nozzle pincher 13 from the upper end portion (horizontal support portion 13a) and both side surfaces (vertical pinching portion 13b). The bending is suppressed not only when the liquid package is poured, but also before and after the liquid package, and particularly when the liquid package is poured, the dispensing nozzle 3 is prevented from swinging up, down, left and right. Therefore, the discharge directionality (directivity) of the liquid package can be improved.

  Further, when the flat upper portion 12c, the nozzle pincher 13 and the dispensing nozzle 3 are fitted (stored) in the groove portion 14b of the opening / closing lid 14, the exposure to the outside of the dispensing nozzle 3 is prevented. Therefore, hygiene at the time of handling or storage can be improved, and the pouring passage 4 of the pouring nozzle 3 is tightened through the vertical pinching portion 13b of the nozzle pincher 13 by pressing by the opening / closing lid 14. Because the sealing container 11 is sealed, the holding container 11 may fall over or mix the liquid package regardless of whether or not the tip opening 7 is formed in the dispensing passage 4 of the dispensing nozzle 3. Therefore, even if shaken or the like, unintended leakage of the liquid package can be sufficiently prevented.

  In addition, as shown in FIG. 3B, the nozzle pincher 13 has an end face shape when the tightening by the opening / closing lid 14 is released, and has an inverted V-shaped cross section that forms a letter C. The shape is preferred. In this case, the nozzle pincher 13 is positioned away from both side surfaces of the dispensing nozzle 3 when the open / close lid 14 is raised upward to assume the release (opening) posture. The liquid packaging material can be smoothly poured out without hindering the dispensing of the liquid packaging material from the dispensing nozzle 3. Further, since the nozzle pincher 13 can be easily fitted into the groove 14c of the opening / closing lid 14, and the nozzle pincher 13 can be gradually sandwiched from the upper side to the lower side by the opening / closing lid 14, the dispensing nozzle 3 can be dispensed. Even if the liquid package remains in the passage 4, when the lid 14 is closed, most of the liquid package is moved downward (packaging bag body 2) as the nozzle pincher 13 is tightened. The liquid package is less likely to scatter from the nozzle tip opening 7 and stain the surroundings.

  Furthermore, in order to quickly and surely release the tightening of the dispensing nozzle 3 by the nozzle pincher 13 when the tightening by the opening / closing lid 14 is released, the end of the horizontal support portion 13a of the nozzle pincher 13 on the hinge hole 15 side. It is preferable to make the wall thickness by providing projections, etc. According to this, when the opening / closing lid 14 is rotated upward, the wall thickness portion is formed on both sides by a pair of plate-like wall surfaces 14a. As a result, the vertical clamping portion 13b side opens according to the principle of the lever, and the tightening of the dispensing nozzle 3 can be reliably released.
