JPH10324339A - Individually-packaging container for pushing out two liquids - Google Patents

Abstract

PROBLEM TO BE SOLVED: To mix liquids well with one touch, by forming a lid from a laminate film consisting of an inner layer having a zone where notches are made and a releasing agent is applied and an outer layer bonded on it, and by disposing the releasing-agent application zone into a proper position. SOLUTION: A lid is formed from a laminate film consisting of an inner layer having a zone where notches are made and a releasing agent is applied, and an outer layer bonded on it. In the case, the releasing-agent application zone is formed in the position where contents in both compartments are pushed out at the same time. Bending the container presses both the compartments against each other, causing to increase inner pressure in each, thereby pushing out the contents into the releasing-agent layer through the notched of the inner layer of the lid. Thus, the two kinds of contents are mixed together in the releasing-agent layer and pushed out from a push-out opening made in the outer layer.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail.

First, the concept of a two-pack extruded individual packaging container filled with the contents of the present invention will be described with reference to the drawings.

FIGS. 1A to 1C relate to a two-pack extruded individual packaging container A. FIG. In FIG. 1A, (a) is a schematic diagram of a two-pack extruded individual packaging container, and (b) is a cross-sectional view taken along a plane perpendicular to a bent portion. In FIG. 1B, (a) shows the shape of the notch of the lid and the position of the release agent application section, and (b) folds the two-pack extruded individual packaging container of such a lid so that the lid is on the outside. FIG. 3 shows a mechanism (conceptual diagram) perpendicular to the bending line showing a mechanism in which two kinds of contents are mixed and extruded. Such a two-pack extruded individual packaging container is bent at the time of use to extrude the contents, but when both chambers are pressed together by this bending and their internal pressure is increased, the contents of both chambers are formed on the inner layer of the lid material. It passes through the notch and is extruded into a release agent layer having low adhesive strength, where it is combined and mixed and extruded from an extrusion port provided in the outer layer.
FIG. 1C shows another example of the shape of the notch of the lid material and the position of the release agent application section.

According to the two-pack extruded individual packaging container A of the present invention, two types of contents can be mixed well with one touch. The two liquids in the present invention are not limited to different kinds of contents, and may be completely the same contents.

FIG. 2 relates to a two-pack extruded individual packaging container B. In FIG. 2, (a) shows the shape of the notch of the lid material and the position of the release agent application section, and (b) shows the state when one chamber of the two-pack extruded individual packaging container of such a lid material is pressed. The mechanism by which the contents are pushed out into the other chamber is shown in a cross section perpendicular to the boundary between the two chambers. When such a two-pack extruded individual packaging container presses one chamber at the time of use, the contents are pushed through a notch in the inner layer of the lid material of the chamber and extruded into a release agent layer having a weak adhesive force, and The contents of both chambers are mixed by being pressed into the other chamber through the notch in the inner layer of the lid of the other chamber. Next, when the other chamber is pressed, the contents are pressed into the one chamber in the reverse route. According to the two-component extruded individual packaging container B (preceding mix type), the liquids in the two chambers are mixed better in this way as compared with the two-component extruded individual packaging container A, though they are two-touch. To pour out the mixture, for example, at least one of the two chambers is provided with a notch at an appropriate position on the peripheral seal portion, and after mixing of the contents of the two chambers, the notch is cut open and the spout is opened. And can be performed from this opening.

Next, a method of manufacturing the lid material of the two-pack extruded individual packaging container of the present invention will be described.

As described above, this lid member is composed of a laminated film composed of an inner layer having a section coated with a notch and a release agent, and an outer layer laminated thereon. Can be easily prepared by utilizing a gravure printing machine.

That is, at the time of printing, a receiving roll equipped with a die convex blade or a punching blade for V-cut, U-cut or the like for providing, for example, a plurality of parallel I notches, turtle notches, round notches or the like is used as a plate cylinder. At the position of
In addition, by using a printing machine that prints the release agent with the plate cylinder, a predetermined position where the notch processing of the inner layer film is desired at a high speed operation (that is, the raw material of the lid material of the laminated film is cut and sealed to the container body. Then, as described above, the release agent application section is moved to a position where the contents of both chambers are simultaneously extruded (two-component extruded individual packaging container A) or a position where the two chambers can be moved mutually. (Two-component extruded individual packaging container B)) can be efficiently notched and a release agent can be applied.

FIG. 3 illustrates a printing machine in which a receiving roll provided with a die convex blade for forming a plurality of parallel I notches is mounted at the position of a plate cylinder. FIG. The printing press incorporated in the sixth unit of the color printing gravure printing press is shown, in which the raw material (B) of the inner layer film is sent out from the supply unit (A), and the release agent is first printed by the printing unit to which the plate cylinder 1 is attached. After that, printing such as display of contents and aesthetic appearance is performed by the printing units 2 to 5 to which the plate cylinders 2 to 5 of each color are sequentially mounted, and then an I-notch processing unit to which a receiving roll 6 to which a die convex blade is mounted is mounted. Is pressed against the plate surface by the pressure roller (C) at the position (1), an I-notch imparting process is performed, and the film is wound at the winding section (F).

FIG. 4 shows a receiving roll. (A) shows the structure of a receiving roll for inserting an I notch, in which ruled lines for sticking a die convex blade in a strip shape are formed at predetermined positions to be notched at intervals. (B) shows the shape of one die convex blade fitted into the narrow groove of the receiving roll, and (c)
Shows an enlarged view of the die convex blade. The height of the blade is appropriately adjusted depending on the diameter of the small diameter portion provided on the receiving roll.

The release agent is applied to a predetermined position in this manner, and the notched inner layer is laminated on the release agent application surface via an adhesive layer or by heat welding. Then, the laminated film of the lid material is completed.

As the adhesive, for example, a urethane-based adhesive "Adcoat AD-900" (Tokyo Morton Co., Ltd.)
Manufactured).

The lid of the laminated film is sealed with the container body by the inner layer, and the contact with the contents (food) is also the inner layer. Therefore, the material of the inner layer is a sealant film. However, it is limited to films having high safety, and examples thereof include general-purpose polyolefin and special polyolefin films. Specifically, low density polyethylene (LDPE), medium density polyethylene (MDPE), high density polyethylene (HDP)
E), unstretched polypropylene (CPP), linear low density polyethylene (L-LDPE), very low density polyethylene (VLDPE), ethylene / vinyl acetate copolymer (EV)
A), ethylene / acrylic acid copolymer (EAA), ethylene / methacrylic acid copolymer (EMAA),
Ethyl acrylate copolymer (EEA), ethylene methyl methacrylate copolymer (EMMA), ethylene
It is a soft packaging material film such as a methyl acrylate copolymer (EMA) and an ionomer (IO).

As a release agent, a polyamide / silicon release varnish "X218PE" (Toyo Ink Co., Ltd.)
Products), acrylic / urethane-based "Shrink EX Medium" (manufactured by Toyo Ink Co., Ltd.), "Rio Fresh" (manufactured by Toyo FCC Co., Ltd.), and a lacquered resin-based edible ink containing calcium carbonate. Can be.

Incidentally, "Rio fresh" and peeling varnish "X
218PE ”has a lamination strength of 1 to 30 g / 15
mm width and weak. Further, in order to effectively weaken the sealing strength of the release agent-applied surface, an inorganic substance such as calcium carbonate may be added to the release agent in an amount of 1 to 10% by weight, preferably 2 to 5% by weight. Examples of the inorganic substance include magnesium oxide, aluminum oxide, titanium oxide, magnesium carbonate, zinc carbonate, calcium sulfate, barium sulfate, sodium silicate, magnesium silicate, viscosity, diatomaceous earth, talc, kaolin and the like.

The outer layer of the lid of the laminated film is selected from heat-resistant materials in consideration of the fact that the two-pack extruded individual packaging container of the present invention may be heated in a microwave oven. Soft wrapping materials such as polyethylene terephthalate film, silica-deposited polyethylene terephthalate film, alumina-deposited polyethylene terephthalate film, biaxially-stretched polypropylene film, and biaxially-stretched nylon film are preferred from the viewpoints of properties, strength physical properties, transparency, printability, and moisture resistance. Can be used.

The lid material must have strength to withstand the bending and pressing of the two-pack extruded individual packaging container of the present invention when used (for pushing out or pouring out the contents), and for the inner layer. An effective notch must be formed and both the inner and outer layers must be strong enough to allow the contents to move through the release agent layer. From this point of view,
The thickness of the inner layer is not unequivocally defined by the type of sealant used, but is usually about 10 to 100 μm, preferably 10 to 50 μm, and the outer layer is usually 1 to 50 μm.
The thickness of the entire lid material is 0.1 to 100 μm.
0.3 mm.

The container body must also have strength to withstand bending and pressing when the two-component extruded individual packaging container of the present invention is used, and the inner surface is in contact with the contents so that it is highly safe. In addition, the sealing surface of the periphery of the opening with the lid material must be suitable for sealing by heat welding with the lid material. As a material of such a container body, polyethylene terephthalate (PET), o-nylon (ONy), polystyrene, various types of polyethylene, polypropylene, and the like can be used as typical materials. The thickness of the container body is 0.1 to 0.3 mm.

The shape of the container body is not limited to a shape in which two trapezoids are connected at a cross section perpendicular to the folding line as seen in the case of FIG. In particular, in the case of the two-pack extruded individual packaging container B of the present invention, the elliptical shape is convenient for moving the contents between the two chambers (FIG. 2B).

There is no particular difficulty in the method of producing the two-pack extruded individual packaging container of the present invention in which two different or identical two-packs are filled in the two chambers of the container body, respectively, and all methods can be according to the conventional method. it can. That is, for example, in the case of the two-component extruded individual packaging container A, the container body is formed into a concave shape, and then the content is filled in the container body on a moving belt conveyor, and then the lid material is covered and sealed. At this time, the laminated film of the lid material is sealed at the peripheral edge of the container body with its inner layer such that the notch-processed portion coated with the release agent comes to a predetermined position. Further, an extruding port is formed at least at the outside of the lid material at the position of the connecting portion between the two chambers of the container body.
The depth of the extrusion opening may pass through the outer layer and reach the container body connection, but must not pass through the container body connection. These can be automatically and continuously performed using a raw material of a laminate film having a release agent application section at an appropriate position.

The method of extruding or pouring the contents at the time of use from the two-pack extruded individual packaging container thus prepared is as described above.

The two-component extruded individual packaging container of the present invention is filled,
As a combination of contents to be mixed at the time of use, a combination of oil and vinegar for preparing a dressing can be considered. Of course, the two-component extruded individual packaging container of the present invention is not only used for mixing two different contents, but can also be used for extruding the same two-component as described above. .
