Convenient to. Further, as a container capable of reducing the volume at the time of disposal by separating the bottom wall part of the container from the body part and folding the body part into a flat shape, it has been disclosed in JP-A-10-35635. There is something.
[0003]
[Problems to be solved by the invention]
The container has a barrel portion and a bottom wall portion that are integrally injection-molded, and the bottom wall portion can be separated from the barrel portion so that the barrel portion can be easily crushed. It is the structure which is provided integrally. For this reason, there existed a fault which a shaping die became complicated and manufacturing cost became high.
[0004]
In addition, although a breaking means comprising a recess is formed around the entire circumference of the bottom wall portion between the trunk portion and the bottom wall portion, the trunk portion and the bottom wall portion are integrally formed of a rigid synthetic resin. Therefore, a strong force is required for dividing the bottom wall portion, and only the knob portion is divided from the bottom wall portion, and there is a possibility that the bottom wall portion cannot be reliably divided.
[0005]
Therefore, the present invention has been made in view of the above-described conventional problems. Instead of integrally molding the body portion and the bottom wall portion with a molding die as in the prior art, the cylindrical body portion is formed with a molding die. In addition to molding, the bottom wall member is made of a flexible sheet and sealed to the body, so that the bottom wall member can be easily and reliably separated from the body at the time of disposal, and the manufacturing cost can be reduced. The challenge is to make it.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
The container 1 according to the present embodiment is for foods in which beverages such as cup noodles and soup that are poured by pouring hot water are accommodated. For example, the container 1 includes a cylindrical body 4 and a bottom wall member 8. A cylindrical label 13 is externally fitted to a container body 3 configured in a cup shape.
[0011]
The body 4 has a rigidity formed by injection molding a synthetic resin material, and is a molded product having an upper surface and a lower surface that are open. The body 4 has a circular cross section and has a tapered shape with a diameter that decreases downward. ing. Examples of the resin material include plastic materials such as polypropylene, polyethylene, polystyrene, polyvinyl chloride, polyester, and polycarbonate.
[0012]
A large number of ribs 6,... For reinforcement are provided radially on the outer peripheral surface of the body 4, and each rib 6 is provided continuously in the vertical direction (vertical direction) of the body 4. Yes. Moreover, the upper part of the trunk | drum 4 becomes the part (large diameter part) 4a which is cylindrical and the curved surface is not provided with the flat rib without an unevenness | corrugation, The upper end of each rib 6 is set to this large diameter part 4a. Are connected, and the outer surface of each rib 6 and the outer surface of the large diameter portion 4a are flush with each other.
[0013]
Further, an annular seal portion 4 b is projected from the inner peripheral surface of the lower end portion of the body portion 4. Then, as shown in FIG. 6, for example, a cross-shaped connecting portion 5 is connected to the seal portion 4b in the diameter direction. The connecting portion 5 reinforces the function of the runner for completely spreading the resin over the entire body portion 4 and the flexural strength of the body portion 4 when the body portion 4 is formed by a molding die. It has the function to do. The connecting portion 5 is formed thinner than the seal portion 4b. Further, as shown in FIG. 4, a recessed portion (notch with a reduced thickness) 5a is formed at the connection position between the seal portion 4b and the connecting portion 5 as shown in FIG.
[0014]
Further, an annular foot 7 projects downward from the lower end of the body 4, and each rib 6 extends to the outer peripheral surface of the foot 7.
[0015]
The bottom wall member 8 is made of a flexible sheet, for example, a laminate film obtained by laminating an aluminum foil, a synthetic resin film, and a heat sealing resin. The bottom wall member 8 includes a bottom wall member main body 8a having a circular shape along the inner peripheral surface of the body portion 4, and a knob portion 8b protruding from a part of the outer periphery thereof. And the peripheral part of the bottom wall member main body 8a is heat-sealed in a sealing manner on the lower surface of the seal part 4b of the body part 4. The bottom wall member 8 has a strength that does not break with a chopstick or a fork when the contents are eaten, and the sealing strength is inadvertently peeled off when the contents are eaten. However, the strength is set such that the consumer can pick the knob 8a and peel it off.
[0016]
The upper end opening of the body part 4 is hermetically sealed with a seal lid 16 made of a laminate material such as an aluminum foil and a synthetic resin film or paper.
[0017]
The label 13 is a known film made of polyester, polyvinyl chloride, polystyrene, polypropylene, polyethylene or the like having a thickness of about 20 to 80 μm, and has a property of heat shrinking at a predetermined shrinkage rate in at least one direction. The inner surface of the label 13 is coated with a heat-sensitive adhesive that is activated by heat at the time of thermal contraction of the label 13 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, although the container body 3 is formed in a tapered shape, the label 13 is held without being displaced downward from the container body 3.
[0018]
Further, since the label 13 is formed so that its longitudinal length is longer than the longitudinal length of the body portion 4, its lower end portion 13a is bent inward from the lower end edge of the foot portion 7 as a result of heat shrinkage. It faces along the peripheral edge of the bottom surface (bottom wall member 8) of the container body 3. Moreover, the knob 8 b is bent toward the center of the body 4 so as to be interposed between the bottom wall member main body 8 and the lower end of the label 13, and is covered by the bottom bent portion of the label 13. Since it looks like, the knob 8b cannot be easily touched while the label 13 is externally fitted to the container body 3.
[0019]
Further, since the knob portion 8b is housed inside the label 13, there is no possibility that the entire container body 3 is lifted or tilted by the knob portion 8b, and the knob portion 8b becomes an obstacle when the container body 3 is used. There is nothing.
[0020]
A perforation 14 is formed along the longitudinal direction of the label 13, and the label 13 can be peeled from the container body 3 by breaking the label 13 along the perforation 14 in the longitudinal direction. At this time, the picking part 8b is exposed to the front side and can be picked.
[0021]
The container 1 according to the present embodiment has the above configuration. Since the body 4 of the container 1 is formed by injection molding of the synthetic resin, it has rigidity and durability, and can sufficiently protect the contents during handling such as transportation of the container 1.
[0022]
When the container 1 is discarded after the seal lid 16 is peeled off and the contents are eaten, first, the label 13 is peeled off from the body portion 4, and then the knob portion 8 b is picked and pulled to thereby remove the bottom wall member 8. And can be completely separated from the body 4 (see FIG. 5). As a result, the body 4 has a cylindrical shape with both upper and lower sides opened, and can be easily crushed and folded into a flat shape, and can be discarded in a compact state without being bulky. .
[0023]
In the container of the present embodiment, the connecting portion 5 is connected to the lower portion of the body portion 4, but since the width is small, the body portion 4 can be easily bent when being crushed, or the notch 5a. Since the notch 5a portion is easily broken, the connecting portion 5 is not hindered when it is crushed.
[0024]
Note that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.
For example, the connecting member 5 is not necessarily provided. Further, the material and thickness of the label 13 are not particularly limited, and it is not necessary to have a shape that completely fits the outer peripheral surface of the body portion 4. These can be appropriately changed according to the use and the shape of the container body 3. Therefore, the shape and size of the container body 3 are not limited. In addition to heat-shrinkable labels (shrink labels), well-known packaging members made of non-heat-shrinkable plastic films, paper, synthetic paper, etc. can be used as the outer fittings attached to the container body 3.
[0025]
Furthermore, the present invention is not limited to the above-described embodiment in which a large number of ribs 6,... A groove-shaped recess may be provided to make the body part 4 easy to fold, or those not provided at all.
[0026]
Further, in the case where the flange portion is provided at the upper end periphery of the body portion 4, a notch may be formed on the outer peripheral surface of the flange portion in order to improve the folding property of the flange portion. In addition to the circular shape, the cross-sectional shape of the container body 3 (body portion 4) and the shape of the bottom wall member 8 can be of any shape such as a rectangular shape, a hexagonal polygonal shape, or an elliptical shape.
[0027]
Further, the label 13 and the seal lid 16 indicate, “When disposing, the label 13 is broken along the perforation 14 and the knob 8b is pulled to separate the bottom wall member 8 from the body 4, and then, If a note to the effect that “the body 4 is folded in a flat shape” is noted, there is a further effect of preventing erroneous opening.
[0028]
【The invention's effect】
As described above, in the container according to the present invention, the barrel portion is formed by injection molding, and the bottom wall member separate from the barrel portion is formed of a flexible sheet. The bottom wall member can be easily and reliably separated from the body portion at the time of disposal. In addition, the body portion can be easily formed by a molding die having a simple structure, and the bottom wall member can be easily formed, which has the advantage of reducing the manufacturing cost.
[0029]
Further, the bottom wall member is provided with a bottom wall member main body sealed to the body portion, and a knob portion protruding from a peripheral edge of the bottom wall member main body, and a tubular label is provided on the body portion. If the bottom wall member is folded to the bottom wall member body side so as to conceal the knob portion folded to the center side of the body portion, the bottom wall member is unsealed. Can be suitably prevented.
