DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a first embodiment of the present invention will be described.

As shown in FIG. 1, a cartridge type tray container A according to an example of the first embodiment of the present invention comprises:
In the illustrated example having a tapered shape provided with a flange portion 11 in an opening portion having a shape retaining property, a rectangular tray container lower body 1 is shown.
In the example shown in the figure, the upper portion 2 has a tapered shape provided with a flange portion 21 at an opening having a shape-retaining property, and the upper portion 2 is a tray container, and a pouring port 3. The tray container lower body 1 and the tray container upper body 2 have a shape joined by a flange 11 and a flange 21.

As shown in FIG. 2, the tray container lower body 1 has a basic layer made of a paper layer 1a and a plastic film layer 1b adhered to the inner surface, and the tray container upper body 2 is joined by heat sealing. By doing so, the cartridge type tray container A having high sealing performance is obtained. The close contact between the paper layer 1a and the plastic film layer 1b of the tray container lower body 1 is in a state where it can be easily separated except for the flange portion 11. The flange portion 11 has a flat shape with no steps. By making it flat,
The cartridge type tray container A having high sealing performance can be obtained by heat sealing with the tray container upper body 2.

The shape of the tray container lower body 1 may be a polygon such as an octagon other than a square having an opening and a bottom as shown in FIG. Further, there is no particular limitation such as a rectangular opening and an octagonal bottom.

As the paper layer 1a, for example, a basis weight of 15
Various paperboards, processed papers, etc. of about 0 to 600 g / m ² can be used.

The plastic film made of the thermoplastic resin forming the plastic film layer 1b may be any film made of a thermoplastic resin having water resistance, sealing properties, and heat sealing properties. Polyethylene (PE), polypropylene (PP), polyvinyl chloride, polyethylene terephthalate (PET), ethylene-vinyl acetate copolymer, ionomer, ethylene-acrylic acid copolymer, polyamide, polyvinylidene chloride, polystyrene, Films of various thermoplastic resins such as saponified ethylene-vinyl acetate copolymer, polycarbonate, polybutene, polyvinyl alcohol and others can be used alone or as a laminate. In particular,
When it is desired to impart gas barrier properties to the container, for example,
Ethylene-vinyl alcohol copolymer (EVO
H) laminated sheets laminated with gas barrier materials such as
Specifically, PE / EVOH / PE, PP / EVOH /
A laminated sheet having a layer configuration such as PE, A (amorphous) and PET / EVOH / PE can be used.

The thickness of the plastic film layer 1a is in the range of 30 to 250 μm, and the moldability of the film itself, the capacity of the container to be molded, and the ratio of the deep drawing (depth / depth)
The diameter is appropriately determined depending on, for example, the diameter, but is preferably 50 to
The range is 100 μm. However, since the strength of the container is mainly provided by the outer paper layer 1a, the thickness can be extremely reduced as compared with the case of a molded container made of plastic alone. From the viewpoint of environmental protection, it is preferable to set the minimum thickness in order to reduce the composition ratio of plastic.However, if the thickness is too thin, the barrier properties are poor and pinholes are easily generated. Since there is a problem, it is necessary to appropriately set it in consideration of the type of the film, the size of the container, and the like.

In the lower tray body 1, a plastic film made of a thermoplastic resin is adhered to the inner surface of the paper layer 1a.
In (1), since the tray container upper body 2 is heat-sealed and sealed, sufficient adhesion strength is required. For this purpose, a heat-adhesive resin such as a heat sealant or a hot melt material is applied to the paper layer 1a of the flange portion 11 in advance. As a result, in the flange portion 11, the paper layer 1a and the plastic film layer 1 are formed in the manufacturing process of the tray container lower body 1 or the heat sealing with the tray container upper body 2.
b can be thermally bonded.

By joining with the container lower body 1 by heat sealing, a cartridge type tray container A having high sealing performance is obtained. The close contact between the paper layer 2a and the plastic film layer 2b of the tray container upper body 2 is in a state where it can be easily peeled except for the flange portion 21.
The flange portion 21 has a flat shape with no steps. By making it flat, a cartridge type tray container A having high sealing performance by heat sealing with the tray container lower body 1 can be obtained.

The shape of the tray container upper body 2 is the same as that of the tray container lower body 1 in this embodiment, but may be different as long as the tray container lower body 1 can be joined at the flange portion.

As the paper layer 2a and the plastic film layer 2b, the same material as the tray container lower body 1 can be used.

In the tray container upper body 2, similarly to the tray container lower body 1, a plastic film made of a thermoplastic resin is adhered to the inner surface of the paper layer 2 a, but in the flange portion 21 of the tray container upper body 2. Therefore, a sufficient adhesive strength is required because the tray container lower body 1 is heat-sealed and sealed. Therefore, the paper layer 2a of the flange portion 21
, A heat-sealing agent or a hot-melt material such as a hot-melt material is applied in advance. Thus, in the flange portion 21, the paper layer 2a and the plastic film layer 2b can be thermally bonded to each other in the manufacturing process of the tray container upper body 2 or the heat sealing with the tray container lower body 1.

The pouring inlet 3 is provided on either the side of the tray container lower body 1 or the side surface of the tray container upper body 2 of the cartridge type tray container A, and has a flange portion 3a which comes into contact with the inner surface of the cartridge type tray container A.

The flange portion 21 has a flat shape with no steps. By making it flat, the tray container lower body 1
Thus, it is possible to obtain a cartridge type tray container B having high sealing performance by heat sealing.

The shape of the tray container upper body 2 is the same as that of the tray container lower body 1 in this embodiment, but may be different as long as the flange portion 21 can be joined to the flange 11 of the tray container lower body 1. . However, in the second embodiment, the capacity of the tray container upper body 2 is preferably smaller than the capacity of the tray container lower body 1. As a result, the volume of the plastic film layer 2b peeled from the tray container upper body 2 entering the tray container lower body 1 is smaller than the volume of the tray container lower body 1,
The ink can be discharged smoothly to the end.

As the paper layer 2a and the plastic film layer 2b, the same material as the tray container lower body 1 of the cartridge type tray container A of the first embodiment can be used.

In the tray container upper body 2, similarly to the tray container lower body 1, a plastic film made of a thermoplastic resin is adhered to the inner surface of the paper layer 2 a, but in the flange portion 21 of the tray container upper body 2. Therefore, a sufficient adhesive strength is required because the tray container lower body 1 is heat-sealed and sealed. Therefore, the paper layer 2a of the flange portion 21
, A heat-sealing agent or a hot-melt material such as a hot-melt material is applied in advance. Thus, in the flange portion 21, the paper layer 2a and the plastic film layer 2b can be strongly adhered to each other in the manufacturing process of the tray container upper body 2 or the heat sealing with the tray container lower body 1.

The pouring inlet 3 is provided on the bottom surface 12 of the tray container lower body 1 of the cartridge type tray container B.

When the contents are filled into the cartridge type tray container B, the shape becomes as shown in FIG. 8A. However, when the contents are completely taken out from the pouring port 3 by suction, FIG. As shown in -b, the plastic film layer 2b adhered to the inner surface of the tray container upper body 2 is peeled off, and the content storage space in the cartridge type tray container B is reduced. Finally, as shown in FIG. 8C, the ink is consumed with little remaining. Since there is a space in the vicinity of the pouring inlet 3 where the suction force acts, the last ink is collected there and is sucked out. Therefore, since there is a space where ink remains at the end, the ink is discharged without remaining. for that purpose,
It is preferable that the volume of the plastic film layer 2b peeled from the tray container upper body 2 into the tray container lower body 1 is smaller than the volume of the tray container lower body 1. That is, the capacity of the tray container upper body 2 is preferably smaller than the capacity of the tray container lower body 1.
