DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container capable of storing food and used as it is as a tableware, a lid material used for the container, and a package sealed with the lid material.

[0002]

2. Description of the Related Art A conventional container of this kind has a tapered shape in which a peripheral wall is vertically or outwardly opened from a bottom wall, and is used for infants, elderly people, persons with disabilities, etc., who cannot move their hands. If
When the contents are scooped out of the container with a spoon or fork, the contents may spill out of the container over the opening rim or flange, or the contents may be spilled when the container is tilted. was there.

[0003]

For this reason, there is a container in which a return portion is formed in which the upper end of the peripheral wall is inclined inward, and the opening is narrowed. However, in such a container, when the contents are scooped with a spoon or the like, the contents are caught in the return portion, or the contents are clogged in the corner of the return portion, and the return portion often becomes an obstacle because the contents cannot be scooped well. . Of course, if the return portion is very narrow, a problem similar to that of the above-described ordinary container occurs, and if the return portion is too wide, the above-described obstacle in taking out the contents is further amplified. Further, since stacking of containers cannot be performed, there is a problem that a large space is required for transportation and storage.

[0004] Therefore, a first object of the present invention is to make it easy to scoop the contents in a container with a spoon or the like, to prevent the contents from spilling out of the container, and to prevent the contents from spilling even if the container is tilted by mistake. It is to be.

[0005] A second object of the present invention is to provide a lid material for obtaining a container which is easy to scoop up contents and hardly spills, and a package in which the container is sealed with the lid material.

[0006]

In order to solve the above-mentioned first problem, the present invention relates to a dishware container having a bottom wall and a peripheral wall rising from the peripheral edge thereof, the flexible container protruding inward near the upper end opening of the peripheral wall. Thus, a configuration in which an overhanging portion having the property and elasticity is provided is adopted. The protruding width of the eaves is 1 mm or more, preferably 5 mm or more, and the inner dimension of the container opening is 2 mm.
0% or less is good. The flexibility and elasticity are 4 Mpa · mm
５００500 Mpa · mm is preferred. The angle between the eaves and the peripheral wall is preferably 10 degrees or more, and the angle between the eaves and the vertical line is preferably 180 degrees or less.

In order to solve the second problem, according to the present invention, an outer release layer is laminated on an adhesive base film via an easily peelable adhesive layer, and the base film is provided near an opening of a container. A through cut is provided to define the inner edge of the eaves projecting inward from the edge. When the container opening is sealed with this lid material, a package is obtained, and when the outer surface peeling layer is peeled off, the container serves as a tableware container having the above-mentioned eaves portion.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIGS. 1 and 2, the dishware container of the present invention has a bottom wall 1 and a peripheral wall 2 rising from the peripheral edge thereof, and an eaves portion 4 a extends inward from near the upper end opening 3 of the peripheral wall 2. It is protruding. In order to form the eaves portion 4a, it is easy to fix the band-shaped film 4 to the flange 5 provided on the outer periphery of the opening 3. The film 4 must be flexible and have resilient elasticity, and the protruding length (width) of the portion serving as the eaves portion 4a must be at least a certain value. Here, when the tensile elastic modulus of the film × the thickness is used as an index of the flexibility and the restoring elasticity, 4 Mpa · mm
As mentioned above, 500 Mpa * mm or less is preferable. The protrusion width W is 1 mm or more, 20% or less of the inner size of the container opening,
In particular, the thickness is preferably more than 5 mm and 20 mm or less. The inside size of the container opening is an average value of the inside and outside dimensions of the opening 3. By selecting the flexibility / elasticity of the film 4 and the projection width W in this manner, the contents in the container are easily scooped with a spoon or the like, so that the contents are not spilled out of the container, and even if the container is tilted by mistake, Things are hard to spill. The strip film 4 may be a laminate.

The eaves portion 4a may be provided on the entire inner periphery of the opening 3 as shown in FIG. 2, but may be partially omitted as shown in FIG. Further, as shown in FIG. 4, one or more division cuts 4b may be provided. By providing the division notch 4b, the eaves portion 4a is more easily bent. Further, as shown in FIG.
May be provided. The shape of the notch 4c is arbitrary,
When the shape is smooth as shown in the figure, the catch when scooping out the contents is reduced. At this time, it is preferable that the tip of the eaves portion 4a also has a smooth radius.

[0010] As shown in FIG.
It does not need to protrude from the upper edge. It suffices if it is around the opening 3. Further, it is not always necessary to be horizontal, and may be curved as shown in FIG. In short, as shown in FIG. 8, the angle θ with the peripheral wall 2 is 10 degrees or more, and the angle γ with the vertical line P is 180 degrees or less, preferably 120 degrees or less.

When the eaves portion 4a as described above is formed, FIG.
As shown in FIG. 4, when scooping out the contents C with the spoon S, the eaves portion 4a having flexibility and elasticity presses the contents so as to cover the contents, so that the contents fall out from the opening 3 to the outside. Can be prevented.

FIG. 1 shows a lid member for forming the eaves portion 4a.
0 is shown. As shown in the drawing, the lid member 10 has a heat sealing layer 12 provided on one surface of a base film layer 11 and an outer surface peeling layer 14 laminated on the other surface via an easily peelable adhesive layer 13.
The base film layer 11 is made of a material having the same flexibility and restoring elasticity as the band-shaped film 4. Of course, it may be a laminated film. The heat sealing layer 12 is made of a sealant for heat-sealing the lid material 10 to the opening of the container. However, if the base film itself has heat adhesion, this layer 12 can be omitted. The easily peelable adhesive layer 13 is formed by forming the outer surface peeling layer 14 into the base film layer 11.
It is a resin layer having a weak adhesive strength that can be easily peeled off by hand, and can be formed by part-coating in an arbitrary pattern such as a dot shape or a stripe shape in order to adjust the adhesive force. Moreover, the resealable pressure-sensitive adhesive layer may be used. The adhesive strength of the easily peelable adhesive layer 13 is lower than the adhesive strength of the heat sealing layer 12. The outer surface release layer 14 may be any of a single substance or a composite substance such as a synthetic resin film, metal foil, paper, or nonwoven fabric, and may have a printing layer, a coloring layer, and the like.
A cover material 10a shown in FIG. 11 has an adhesive layer 12a having an adhesive strength greater than that of the easily peelable adhesive layer 13 in place of the heat sealing layer 12, and the outer surface thereof is covered with a release paper 14a. The cover material 10a is obtained by peeling the release paper 14a and pasting it by hand to the opening of a normal container to obtain the package of the present invention. A container is obtained.

The cover member 10 has cuts 15 penetrating the heat sealing layer 12 and the base film layer 11, and cuts 1
6 are provided. The cuts 15 and 16 are
After forming 0, it is preferable to provide by a half-cutting method. As shown in FIG. 12, the outline of the cuts 15 and 16 is such that both cuts 15 and 16 are continuous over the entire circumference of the lid member 10 (the container in FIG. 2).
The cut 15 is formed only in the tab portion and the cut 16 is continuous over the entire circumference. As shown in FIG. 14, both ends 16a and 16b of the cut 16 extend to the peripheral edge of the lid member 10 (see FIG. 3). As shown in FIG. 15, the cut 16 is provided with a split cut 17 in an outward direction substantially perpendicular to the cut 16 (the container in FIG. 4), as shown in FIG.
The cut 16 is corrugated (see the container in FIG. 5).
And so on. In the case of FIG. 12 and FIG. 15, the peeling end (having the same function as the tab) of the lid 10 is formed over the entire circumference or almost the entire circumference. Similar cuts 15 and 16 are provided in the case of the lid 10a.

The cut 16 defines the inner edge of the eaves portion 4a shown in FIGS. Therefore, it must be designed so as to satisfy the specific protrusion width W described above.

FIG. 17 shows a state where the lid member 10 is heat-sealed to a container. As shown in the figure, the flange 5 of the container preferably has a downwardly inclined surface 5a extending outward on the entire upper surface thereof. The inclined surface 5a is provided to prevent the heat sealing layer 12 from adhering, and thus, a clue when the lid member 10 is peeled from the container can be easily formed. It is preferable that the cut 15 in FIG. 10 is located just at the top of the inclined surface 5a as shown in FIG.

In the above state, when the edge of the lid member 10 is pinched with a finger, the heat sealing layer 12 and the base film layer 11 are cut at the cut 15 so that the easily peelable adhesive layer 13 is exposed. Then, the lid material 10 is further pulled up, so that the outer release layer 1 is formed along the interface of the easily peelable adhesive layer 13.
Base film layer 11 in which only 4 is fixed to flange 5
From the base film layer 11 due to cohesive failure of the easily peelable adhesive layer 13. This peeling proceeds to the inner cut 16, and after the cut 16, the base film layer 11 is also lifted together with the outer peeling layer 14, and the entire lid 10 is cut off, resulting in the state shown in FIG. That is, a part of the base film 11 remains on the flange 5 of the container, and forms the band-shaped film 4 and the eaves portion 4a shown in FIG. The same applies to the case where the lid member 10a shown in FIG.

Although the figure shows a substantially rectangular container, the present invention is not limited to this. Other polygons, circles, ellipses and the like may be used. The material of the container can be variously selected from synthetic resin, paper, metal, glass, porcelain, and the like. further,
Examples of the container include not only the size of a tableware that can be lifted by ordinary hands, but also a large plate or a large bowl that is used while being placed on a table or a desk.

Hereinafter, more detailed examples will be described.
