DETAILED DESCRIPTION OF THE INVENTION

[0001]

INDUSTRIAL APPLICABILITY The present invention can store two or more foods such as curry and cooked rice, spaghetti sauce and noodles in the same container, and can open the food very easily. For containers.

[0002]

2. Description of the Related Art In recent years, retort foods, microwaved foods, and the like have become widespread, and the contents stored in containers at the time of sale have not been transferred to household lacquer ware, but the containers at the time of sale have been used as they are. In many cases, containers that can be eaten simply by opening the lid are used.

[0003] Further, in the above-mentioned microwave processed food, for example, curry and cooked rice, spaghetti sauce and noodles, etc.
Separately or integrally provided in the tray type container, so that two or more types of food can be stored in the same container. A container that can be sterilized and cooked in time has been devised (see Japanese Patent Application Laid-Open No. 2-154651).

In the container, a laminated film of a metal foil and a plastic or a laminated film composed of only a plastic is used, and the laminated film is heat-sealed around the opening of the container to form a lid. Was formed, and the container was closed.

When the lid is opened, an opening start portion is provided at one end of the periphery of the opening, and the seal is gradually peeled off from the opening start portion to open the lid.

[0006]

However, in a container provided with an internal partition as described above and having a lid closed by heat sealing, when the lid is opened, heat is applied to the upper surface of the partition. The sealed portion is hardly peeled off. In particular, as shown in FIG. 12, when the area of both end portions 39 and 39 ′ of the partition 34 is large, the partition 34
The direction at which the force is applied suddenly changes at the peeling point on the upper surface of the substrate, or in two directions (indicated by arrows A ₁ and A _{2 in} FIG. 12) and in three directions (arrows B ₁ , B ₂ and B in FIG. 12). ₃ ), the force is completely dispersed, making it very difficult to open.

If it becomes difficult to release the heat seal at the peeling point on the upper surface of the partition 34 as described above, the stored items tend to overflow, and the liquid (particularly a liquid which is uniquely colored such as curry roux or spaghetti sauce) is stored. Consumers were often very confused when things were stored.

Therefore, the present invention provides a container capable of storing two or more types of stored items in which the lid is adhered and closed by heat sealing in the same container, and the opening thereof is very easy. An object of the present invention is to provide a container that can be safely opened without fear of spilling.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the container according to the present invention will be described below in detail with reference to the drawings.

As shown in FIGS. 1 and 2, for example, the container of the present invention has a semi-circular shape having flange portions 2a, 2b projecting outward from the opening peripheral portions 1a, 1b. One storage body
3a, 3b are connected to each other via a partition 4 provided flush with the flanges 2a, 2b, and a container body 5 and two housings 3a, 3b of the container body 5. It is composed of flanges 2a, 2b of a container body 5 and a film-like lid 7 bonded to the partition 4 by heat sealing so as to integrally close the openings 6a, 6b.

The heat seal width (t) on the flanges 2a and 2b and the partition 4 is 1 to 12 mm, preferably 2 to 8 mm.
mm is preferable, and as means for opening the adhesion, interlayer peeling, cohesive peeling, interfacial peeling, and the like can be given. The material of the container body 5 and the lid 7 is selected according to the means.

The material constituting the container body 5 includes:
For example, an ethylene-vinyl alcohol copolymer resin containing 10 to 50 mol% of ethylene monomer units (hereinafter referred to as EVO)
Indicated as H. ) Or a hydrophobic resin such as polyethylene, polypropylene, polyethylene terephthalate, ethylene / α-olefin copolymer, or a polyamide-based hydrophilic resin on both front and back surfaces of a sheet substrate made of a modified product using the EVOH as a substrate. Cover sheets are sandwiched and sandwiched, and the like.Containers made of these materials are particularly excellent in gas barrier properties and heat resistance, and thus can be particularly suitable for heating and cooking by microwave irradiation. There is no particular limitation on the material of the container.

The material constituting the lid 7 is, for example, a single layer or a laminate of thermoplastic plastic,
Alternatively, a laminate of a metal foil such as aluminum and a thermoplastic plastic or the like is used.

[0022] One container 3a at one intersection 8 between the flange portion 2a of the partition part 4 and the opening edge 1a (1b) (2b)
One end portion 9 of the partition portion 4 is bent in a curved shape so that the side angle (Q) is formed into a crow-mouthed acute angle, and the opening start serving as a starting point when the lid 7 is opened. Part 10
Is located on the other storage body 3b side adjacent to the storage body 3a having the crow-shaped angle (Q), and the intersection 8 and the partition 4
A line 12 connecting the center point 11 of the
Is formed at a position where the angle (P) between the line and the line 13 connecting the two is acute. That is, the exchange between the partition part 4 and the flange parts 2a, 2b is performed.
One end of the partition part 4 connected to one of the intersection parts 8 of the difference parts 8, 8 '
The shape of the portion 9 is, as shown in FIG.
It is a curved shape that wraps around and is connected to the one intersection 8.
A song having a radius of curvature smaller than the radius of curvature of the flange 2a
, So that one end 9 and the flange 2
The shape of a becomes crow-shaped. In addition, one intersection 8
As an apex, there is a gap between one end 9 of the partition 4 and the flange 2a.
The angle (Q) is formed to be an acute angle. one
The other of the intersections 8 and 8 'of the partition 4 and the flanges 2a and 2b
The shape of the other end 9 'of the partition 4 continuing to the intersection 8'
As shown in Fig. 1, it wraps around in the direction away from the opening start part 10.
A flange that is curved and continues to the other intersection 8 '.
Shaped with a radius of curvature smaller than the radius of curvature of section 2b
Therefore, the other end portion 9 ′ and the flange portion 2b are formed.
The shape becomes a mouth-shaped. In addition, the other intersection 8 '
As the other end 9 ′ of the partition 4 and the flange 2b.
The angle (R) is formed to be an acute angle. Also,
The opening start portion 10 of the lid 7 is provided with the partition portion 4 and the flange portions 2a, 2
At a position closer to one of the intersections 8 of the intersections 8 and 8 'of b,
A line 12 connecting the one intersection 8 and the center point 11 of the partition 4 ,
Angle formed by a line 13 connecting the center point 11 and the opening start portion 10
(P) is provided at an acute angle position.

The angle (Q) of the mouth shape may be any number as long as it is an acute angle, but specifically 30 ° to 70 °, preferably 6 °.
The effect appears most around 0 °. The angle (P) may be any number as long as it is an acute angle, but the effect is most effective when the angle is around 45 °.

The opening start portion 10 of the lid 7 projects outward from the container body 5 to form a portion (non-heat-sealed portion) which is not bonded by heat sealing. As shown in FIG. 3, the flange portion 2b of the container body 5 is further extended in advance in conformity with the protruding shape of the opening start portion 10, and a cut line 14 is formed in the flange portion 2b. Heat seal from above. That is, the lid 7
Are the upper surfaces of the flange portions 2a, 2b and the partition portion 4 of the container body 5.
Is bonded by heat sealing. Therefore, the lid 7 is
Peel the lid 7 from the opening start part 10 toward the center point 11
When separated, the peeling trajectory is
a, 2b via one of the intersections 8, 8 'of the intersection 8,
When branching into the partition 4 and the flange 2a,
Peeling locus on the cut portion 4 side and peeling locus on the flange portion 2a side
The angle (Q) formed by the partition 4 becomes acute, and the peeling of the partition 4 side is performed.
The separation locus and the separation locus on the flange portion 2a side are each curved.
And the radius of curvature of the separation trajectory on the partition 4 side is
A radius of curvature smaller than the separation locus on the flange portion 2a side;
Thus, it is bonded to the container body 5.

When opening the lid 7 of the container as described above, the opening start portion 10 is pulled off or, as shown in FIG. 3, a cut line provided in the extension portion 15 of the flange portion 2b. The opening start portion 10 of the lid 7 may be pulled off together with the extended portion 15 of the flange portion 2b by folding off along 14.

[0026] Then, the lid 7 becomes to be peeled off while being moved parallel to the tangent MN with respect to the container body 5 the opening start part 10 as a starting point (rail effect). At this time , as shown in FIG. 4, at the moment when the seal of the lid 7 is peeled off on the opening peripheral portion 2b of the container 3b on the side where the opening start portion 10 is provided (for example, the tangent MN in FIG. 4). On the ST line parallel to
And approached the storage body 3a having the crow-like acute angle Q,
An instantaneous peeling force (instantaneous peeling area: T ₁ ) at the moment when the seal near the one intersection 8 between the partition part 4 and the flange part 2a is peeled off (for example, on a PQ line parallel to the tangent line MN in FIG. 4).
-T ₂ + T ₃ -T ₄ and Q ₁ -Q ₂ + Q ₃ -P ₃ + P ₁ -P ₂ ) Hardly makes a difference.

That is, when the part to be peeled comes from the opening start part 10 of the partition part 4 to one crossing part 8 formed by the partition part 4 and the flange part 2a, the instantaneous peeling force is reduced. One from the intersection 8 goes to one end 9 of the partition 4 and further to the center 11 (arrow
A ₁ ) and the other is a flange on the opening edge 1a of the housing 3a.
Distributed to 2a (arrow A ₂ ).

[0028] However, even when a force such as this are dispersed, partition
Since the shape of the one end 9 of the part 4 is formed in a curved shape,
The instantaneous peeling force in two directions to be dispersed draws a curve shape, and the opening becomes extremely easy without extremely dispersing the opening direction.

Further, the part to be peeled off by the rail effect is changed from the one end side 9 of the curved part of the partition part 4 to the linear part.
When approaching 16, the direction in which the force is applied changes, and the direction gradually becomes perpendicular to the partition 4 (for example, the straight line EF in FIG. 4, and further the straight line GH).

At this time, the other container at the intersection 8 'between the other end 9' of the partition 4 and the series of flanges 2a, 2b.
In the case where the angle (R) on the 3b side is formed to be a sharp angle in the shape of a crow, the moment when the seal is peeled off on the linear portion 16 of the partition 4 (for example, the UV perpendicular to the partition 4 in FIG. 4) On the line)
Reached the storage body 3b having a crow-mouth-shaped acute angle R,
The instantaneous peeling force (instantaneous peeling area: V) at the moment when the seal near the intersection 8 'formed by the partition 4 and the flange 2b is peeled off (for example, on an XY line perpendicular to the partition 4 in FIG. 4). ₁ -V
₂ + V ₃ -U ₃ + U ₁ -U ₂ and Y ₁ -Y ₂ + Y ₃ -X ₃ + X ₁ -X ₂ . )
Hardly makes a difference.

That is, when the part to be peeled reaches the other end 9 ′ from the straight part 16 of the partition part 4, the peeling force (arrows B ₁ , B ₂ , B ₃ ) dispersed in three directions is increased. Concentration starts toward the intersection 8 'formed by the partition 4 and the flange 2b, and the peeling is completed at a stretch.

Therefore, at the peeling point of the lid 7 on the one end portion 9 and the other end portion 9 'of the partition portion 4, each of the storage bodies 3a, 3
Due to the crow's mouth shape having the angle (Q) and angle (R) formed in b, the direction of the force will be dispersed or concentrated fairly slowly, and the direction of the extreme force will be changed. Since there is no lid, the release of the lid 7, that is, the peeling, is very easy.

Of course, the other end 9 'of the partition 4 does not need to have a flared shape as described above, and may have a normal right-angled shape.

Incidentally, the shape of the container body 5 is
It is not limited to the one in which the three storage bodies 3a, 3b are connected via the partition part 4, for example, as shown in FIG. 5, the two elliptical storage bodies 3a, 3b are connected through the partition part 4. Alternatively, as shown in FIG. 6, two rectangular housings 3a and 3b may be connected via a partition 4. As shown in FIG.

In addition to connecting the storage members 3a and 3b having the same shape as described above, as shown in FIG. 7, the storage member 3a having a semicircular shape and the storage member 3b having a rectangular shape are Alternatively, as shown in FIG. 8, semi-circular storage bodies 3a and 3b of two different sizes may be connected via a partition 4.

Further, the number of the housings is not limited to two, but as shown in FIG. 9, three housings 3a, 3b, 3c are connected by partitions 4a, 4b, respectively. Alternatively, more storage units 3a, 3b... May be connected.

As described above, two or more storage bodies 3a, 3b
Are connected to each other at the point where the force is dispersed and the point where the force is concentrated when the lid 7 is peeled off from the opening start portion 10 and the branching partitions 4a and 4b and the opening. The angles formed by the peripheral flange portions 2a, 2b, and 2c may be configured as acute angles (Q, Q ', R, R') having a crow mouth shape.

Further, in the container main body 5, the storage body
In addition to heat-sealing the lid 7 over the entire surface of the flanges 2a, 2b and the partition 4 at the opening peripheral portions 1a, 1b of the openings 3a, 3b, for example, as shown in FIG. In addition to the projections 17a and 17b provided at the portions, a pair of projections 18a and 18b are provided at both ends in the width direction of the partition 4 and the projections 17a, 17b, 18a and 18b May be bonded by heat sealing.

When the projections 17a, 17b, 18a, 18b are provided, the width (s) of the projections 17a, 17b, 18a, 18b is 0.5 to 10 m.
m, preferably 1.0 to 3 mm.

Next, the partition 4 shown in FIGS.
Concrete improvement of the openability by using a container formed by changing the angles (Q) and (R) in the crow-mouthed acute angle at the intersections 8 and 8 'between the flanges 2a and 2b Examples will be described with reference to experimental examples.

In the experiment, as shown in FIG.
Push-pull testing machine 19, and attached to the testing machine 19,
Opening the container fixed to the testing machine 19 by operating a punch 22 which is connected to a motor 20 via a guide 21 and which automatically opens at an angle of 45 ° while sandwiching the opening start portion 10 of the lid 7. This is to compare the states.

Incidentally, the above-mentioned opened state indicates the peeling force required at the moment of peeling off the seal in kg.
The angle (Q) and (R) of the crow mouth were changed to 5 °, 10 °, 30 °, and 60 °.

The containers used were the containers 3 of the container body 5.
a, 3b are made of polypropylene with a capacity of 350 ml and 250 ml, and one storage unit 3a is filled with 200 g of cooked curry sauce, and the other storage unit 3b is filled with 200 g of cooked cooked rice, Thereafter, a lid 7 composed of a laminate of aluminum foil and polyvinyl chloride (PVC) was closely adhered by heat sealing, and was subjected to ordinary retort sterilization.

As a comparative example, a test container was manufactured under the same conditions as described above in a conventional container in which the angles (Q ') and (R') between the partition 4 and the flanges 2a and 2b were rectangular. It was fixed at 19 and measured.

The above results are shown in Table 1. The measured value is an average of five measurements.

[0046]

[Table 1]

As can be seen from the above results, a comparison between the embodiment of the present invention and the conventional example reveals that the force required for opening is much smaller than that of the conventional example, and that the opening property is clearly improved. I can say.

[0048]

As described above, the container according to the present invention has a lid
The body can be easily peeled off and opened. Therefore, the lid
When the body is opened, the items stored in the container may not fall out.
There is no danger, especially sealing of fluid storage such as curry
It is suitable as a container for storing.
