DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

The container 1 according to the present embodiment includes a heat-resistant cup-shaped container body 3 made of a plastic material such as polypropylene, polyethylene, polystyrene, polyvinyl chloride, polyester, and polycarbonate. A heat-shrinkable cylindrical label 13 is externally fitted from the outer peripheral surface to the bottom surface of the peripheral wall, and an upper end opening of the container body 3 is made of aluminum foil and a laminated material such as a synthetic resin film or paper. It is sealed by a seal lid 16 so that it can be peeled off.

The container body 3 is a molded article having rigidity obtained by injection-molding the above-mentioned synthetic resin material, and has a tapered body portion 4 having a circular cross section and having a diameter decreasing downward as it goes down. And a bottom wall 8 that closes the lower opening end, and has a bottomed cylindrical shape that opens upward as a mouth.

On the outer peripheral surface of the body 4, a number of ribs 6,... For reinforcing the container body 3 are projected radially, and each rib 6 is arranged in the vertical direction (vertical direction) of the body 4. ). The upper portion of the body 4 is a portion (large-diameter portion) 4a which is cylindrical and has no curved ribs and no flat ribs, and the upper end of each rib 6 is provided on the large-diameter portion 4a. Are connected, and the outer surface of each rib 6 and the outer surface of the large diameter portion 4a are flush.

An annular foot 7 is provided at the lower end of the body 4 so as to protrude downward.
It extends to the outer peripheral surface of the foot 7. On the periphery of the bottom wall 8, which is a boundary between the foot 7 and the bottom wall 8, a concave portion (a portion having a reduced thickness) 9 as a breaking means is formed over the entire circumference.

A pull tab 10 is provided on the outer surface of the bottom wall portion 8 and near the concave portion 9 as a breaking means. The pull tab 10 has an opening 10a formed therein so as to be easily picked. ing. The pull tab 10 and the recess 9 are preferably formed at the same time as the injection molding. However, the recess 9 may be provided in a separate step after the molding, and the pull tab 10 is provided separately from the bottom wall 8. A body may be fixed to the bottom wall 8.

The pull tab 10 is formed in a shape bent toward the bottom wall 8, so that when the container body 3 is set up on a table or the like, the pull tab 10 is stored inside the foot 7, and The pull-tab 10 does not hinder the entire container body 3 from being lifted or inclined, and the pull-tab 10 does not hinder the use of the container body 3.

The label 13 is a known film formed of polyester, polyvinyl chloride, polystyrene, polypropylene, polyethylene or the like with a thickness of about 20 to 80 μm, and has a property of thermally shrinking in at least one direction with a predetermined shrinkage. Have. The inner surface of the label 13 is coated with a heat-sensitive adhesive which is activated by heat generated when the label 13 is thermally contracted and exhibits adhesiveness, and the upper portion of the label 13 is placed on the container body 3 via the heat-sensitive adhesive. Is adhered to the surface of the large diameter portion 4a. Therefore, even though the container body 3 is formed in a tapered shape, the label 13 is held without falling down from the container body 3.

Further, the label 13 is formed so that its longitudinal length is longer than the longitudinal length of the body portion 4.
As a result of the heat contraction, the lower end is bent inward from the lower end edge of the foot portion 7 and faces along the peripheral portion of the bottom surface (bottom wall portion 8) of the container body 3. Moreover, the pull tab 10
It is interposed between the peripheral edge of the bottom wall 8 and the lower end of the label 13,
Since the label 13 is covered by the bottom bent portion, the label 13 cannot easily come into contact with the pull tab 10 while the label 13 is externally fitted to the container body 3.

A perforation 14 is formed on the label 13 along its longitudinal direction. The label 13 is peeled off from the container body 3 by breaking the label 13 along the perforation 14 in the longitudinal direction. be able to. At this time, the pull tab 10 is exposed on the front side and can be picked. In addition, a printed layer (not shown) is formed on the front surface or the back surface of the label 13, and the label 13 enables beautiful printed display.

The container 1 according to the present embodiment has the above configuration. Since the container 1 is formed by injection molding the synthetic resin, the container 1 has rigidity and durability,
It is possible to sufficiently protect the contents when handling the container 1 for transportation or the like.

When the container 1 is discarded after the seal lid 16 is peeled off and the contents are used for food, first, the label 13 is peeled off from the container body 3 and then the pull tab 10 is picked and pulled. Since a concave portion 9 having a reduced thickness is formed on the outer periphery of the bottom wall portion 8, the bottom wall portion 8 is broken from the trunk portion 4 along the concave portion 9.

Furthermore, since the concave portion 9 is broken over the entire circumference, the bottom wall portion 8 can be completely separated from the body portion 4 (see FIG. 5). As a result, the body 4 is formed into a tubular shape with both upper and lower sides opened, and can be easily folded flat, and can be discarded together with the bottom wall 8 in a compact state without being bulky. Becomes

It should be noted that the present invention is not limited to the above embodiment, and various changes can be made without departing from the gist of the present invention.

For example, the material and thickness of the label 13 are not particularly limited, and the label 13 does not need to have a shape that completely fits the outer peripheral surface of the body 4. These can be appropriately changed according to the application and the shape of the container body 3. Therefore, the shape and size of the container body 3 are not limited. In addition, a known packaging member made of a synthetic resin such as a plastic film, paper, synthetic paper, or the like, other than the heat-shrinkable label (shrink label), can be used as the one to be externally fitted to the container body 3.
When using a packaging member other than the heat-shrinkable label,
The lower end may be narrowed and bent inward.

Further, according to the present invention, as in the above embodiment,
Not only the body 4 provided with a large number of ribs 6 on the outer peripheral surface thereof, but also a body provided with a concave portion in the vertical direction on the outer peripheral surface and / or the inner peripheral surface of the body 4 so that the body 4 can be easily folded. Alternatively, these may not be provided at all.

Further, the lower end of the packaging member such as a label may be bent so as to cover almost the entire bottom wall by heat shrinkage, or a part of the pull tab 10 may be bent so as to be visible. It may be. The point is that the present invention is intended as long as the breaking means such as the pull tab 10 is not carelessly opened.

Therefore, as in the above embodiment, the label 13
In addition to the container having the lower end portion as the concealing member, the container shown in FIG. 6 can also be employed. The container shown in FIG. 6A has a configuration in which a sheet body 17 such as cardboard is inserted into the inside of the foot portion 7 and the lower end portion of the label 13 externally fitted to the body portion 4 is bent inward from this state. is there. The sheet member 17 is formed in a disk shape having substantially the same diameter as the inner diameter of the foot portion 7, and the peripheral edge of the sheet member 17 is locked to the lower end of the label 13, so that the sheet member 17 is prevented from coming off. ing. Also, FIG.
Is bent inward at the lower end of the label 13 externally attached to the body 4, and a flat sheet 18
Is a configuration in which the peripheral portion is adhered. For these configurations,
The concealing members are the sheet members 17 and 18. If perforations 17a, 18a are provided in the center of the sheet members 17, 18, erroneous opening can be reliably prevented without being mistaken for a seal lid.

In the above embodiment, a heat-sensitive adhesive is used as a means for fixing a packaging member such as a label to the container body 3, but the present invention is not limited to this.

Further, the breaking means may be provided with only the concave portion 9 without providing the pull tab 10. In this case, if the concave portion 9 is provided on the outer surface of the bottom wall portion 8, the bottom wall portion 8 is completely pushed into the body portion 4 so that the bottom wall portion 8 is completely
However, the present invention is not limited to this, and the concave portion 9 can be provided on the inner surface of the bottom wall portion 8. Further, in addition to providing the concave portion 9 over the entire circumference of the bottom wall portion 8, the concave portion 9 may be such that a part of the trunk portion 4 and the bottom wall portion 8 are connected to such an extent that the folding of the trunk portion 4 is not hindered. Good.

Further, as another configuration of the breaking means, a concave portion 9 is provided.
Is formed along the entire circumference or the arc of the bottom wall portion 8, a projection is provided on the outer surface of the bottom wall portion 8 and near the concave portion 9, and the projection portion is pushed into the body 4 so that the bottom wall portion 8 is pressed. May be broken from the body 4.

Further, when a flange portion is provided on the peripheral edge of the upper end of the body portion 4, a notch may be formed on the outer peripheral surface of the flange portion in order to improve the foldability of the flange portion. Moreover, the cross-sectional shape of the container body 3 (the body 4) may be any shape such as a rectangular shape, a hexagonal polygonal shape, or an elliptical shape in addition to the circular shape.

In addition, the label 13 and the seal lid 16 are displayed as follows: "At the time of disposal, the label 13 is broken along the perforation 14, and the pull tab 10 is pulled to separate the bottom wall portion 8 from the body portion 4. After that, note that "the body 4 is folded flat".
