Description

  The present invention relates to an ice cream container, and more particularly to an improved ice cream container for disposal of a lid removed from a cup when eating ice cream.

  Ice cream containers have been stretched from the upper part of the circular frustoconical shape, which is generally reduced in diameter from the upper edge of the circle that borders the opening toward the lower edge of the circle, and the bottom of the cylindrical peripheral wall. It is made into the structure which combined the cup which has a bottom wall, and the lid | cover which closes the said opening of the said cup. Such an ice cream container is made of paper or a thin synthetic resin sheet and does not have the strength and rigidity of a rough material. Therefore, in order to give the cup strength and rigidity, the opening edge of the cup is rolled up with paper. In the case of a synthetic resin, the thickness is somewhat increased. At the bottom of the cup, the lower end of the peripheral wall overlaps with the excess part of the peripheral edge of the bottom wall sheet and is rolled up into a bead shape, or the bottom wall is displaced slightly above the lower edge of the peripheral wall to the bottom wall sheet. The peripheral surplus portion of the peripheral wall is superposed on the inner side of the peripheral wall and extends along the lower end of the peripheral wall to make the lower end portion of the peripheral wall a double structure of the sheet.

  The lid removed from the cup is no longer necessary for eating ice cream that is made of paper or a thin synthetic resin sheet and packed in an ice cream container that will be discarded after use. In the meantime, the lid becomes obstructive because it is necessary. If you eat ice cream at the table, or if there is a trash can nearby, there is no problem disposing of the lid, but if not, the lid may be dumped carelessly Even if you intend to dispose of the ice cream in the proper place with the cup, you may leave it alone and cause environmental pollution.

  On the other hand, in an ice cream container made of paper or a thin synthetic resin sheet, a bead is formed on the opening edge of the cup as described above, or the lower end portion of the cup peripheral wall is reinforced by the joint portion with the peripheral edge excess portion of the bottom wall sheet. However, it is a soft and easy-to-deform cup as a whole, and it is difficult to grasp stably, especially as the contents decrease. Also, since cups made of paper or thin synthetic resin sheets have poor heat insulation properties, if you hold the peripheral wall directly with your fingertips, your fingertips will be overcooled and uncomfortable, and at the same time the ice cream in the cup will be transferred from the fingertip Is dissolved by.

  In view of the above-mentioned problems associated with conventional ice cream cream containers, the present invention aims at appropriate disposal of the lid removed from the cup when eating ice cream, and at the same time, using this lid, the ice cream container The goal is to make the act of eating ice cream more comfortable.

  In order to solve the above-described problems, the present invention provides an inverted frustoconical cylindrical peripheral wall having a diameter reduced from a circular upper edge that borders the opening toward a circular lower edge, and a bottom of the cylindrical peripheral wall. An ice cream container in which a cup having a bottom wall provided and a lid for closing the opening of the cup are combined, and the cup and the cup are fitted to the lower end of the peripheral wall of the cup on the back side of the lid The present invention proposes an ice cream container characterized in that an annular receiving surface is formed which allows the lid and the lid to be joined together by frictional engagement.

  The bottom wall is provided by being displaced from the lower edge of the cylindrical peripheral wall to the upper edge side, and the annular receiving surface of the lid is located on the outer side and the inner side of the portion of the peripheral wall of the cup located below the bottom wall. There may be two annular surfaces in contact with both, and in this case, a part of the two annular surfaces may further be lip-shaped.

  However, the annular receiving surface of the lid may be a single annular surface that contacts only the outside of the lower end of the peripheral wall of the cup, or the bottom wall is lower than the lower edge of the cylindrical peripheral wall. The annular receiving surface of the lid may be a single annular surface that contacts only the inside of a portion of the peripheral wall of the cup that is below the bottom wall.

  Furthermore, the portion of the lid located on the inner side of the annular receiving surface is between the bottom wall of the cup when the lower end portion of the peripheral wall of the cup is fitted with the annular receiving surface of the lid. It is also possible to leave a space for folding and storing the peeled off seal that seals the open end of the cup.

  As described above, a cup having an inverted frustoconical cylindrical peripheral wall that is reduced in diameter from a circular upper edge that borders the opening toward a circular lower edge, and a bottom wall that is stretched on the bottom of the cylindrical peripheral wall And an ice cream container that combines the lid that closes the opening of the cup, and is fitted on the back side of the lid with the lower end portion of the peripheral wall of the cup so that the cup and the lid are integrated by friction engagement. If an annular receiving surface to be bonded to the cup is formed, when the ice cream is eaten, when the lid is removed from the cup, the lid is turned over, and the annular receiving surface formed on the lower end of the cup and the back side of the lid And the lid and the cup are joined together by frictional engagement, the disposal of the lid is completed immediately. In addition, the lid connected to the bottom of the cup stabilizes the cup that is easily deformed and made of paper or a thin synthetic resin sheet without directly touching the peripheral wall of the cup with the fingertip when eating ice cream. The cup support means for supporting the cup uniformly and insulatively along the periphery at the lower end of the cup most suitable for supporting.

  The bottom wall is provided to be displaced from the lower edge of the cylindrical peripheral wall to the upper edge side, and the annular receiving surface of the lid is on the outer side and the inner side of the part of the peripheral wall below the bottom wall of the cup. If the two annular surfaces are in contact with each other, the distance between the two annular receiving surfaces and the thickness of the lower end of the peripheral wall fitted between them are set appropriately, so that the fitting relationship between them can be determined. It becomes easy to appropriately adjust the degree of tightening. In this case, if a part of the two annular surfaces is a lip shape, flexibility and elasticity are given to the interval between the two annular receiving surfaces, and the fitting between the lid and the lower end of the cup is performed. It becomes easier to fit and more firmly connected.

  However, the annular receiving surface of the lid is a single annular surface that contacts only the outside of the lower end of the peripheral wall of the cup, or the bottom wall is on the upper edge side of the lower edge of the cylindrical peripheral wall. If the annular receiving surface of the lid is a single annular surface that contacts only the inside of the portion of the peripheral wall of the cup that is below the bottom wall, it is strong enough to maintain the coupling state. In point, the annular receiving surface may be somewhat inferior to the case of two annular surfaces, but the operation of fitting the lid and cup is easier than when the annular receiving surface is two annular surfaces, and The annular receiving surface can be formed more easily.

  When the lower end of the peripheral wall of the cup is fitted with the annular receiving surface of the lid, the portion located inside the annular receiving surface of the lid is located between the cup and the bottom wall of the cup. In the case of an ice cream container in which the open end of the cup filled with ice cream is sealed with a seal, if the space where the peeled off seal that seals the open end of the cup is folded and stored is left, The hermetic seal peeled off from the open end of the cup is also properly disposed of at the same time as the lid without being inadvertently discarded.

The surface is formed as an inverted U-shaped annular portion. A part of the annular part having an inverted U-shaped cross section is a groove part 36 obtained by deforming the disk part 34, and the remaining part is a pair of annular lips protruding downward from both edges of the groove part. 38 and 40. Therefore, in this case, the main parts of the annular receiving surface 30 are the concave and convex annular surfaces of the lips 38 and 40 facing each other. Such a lid having a cross-sectional shape may be manufactured by injection molding or press molding of a synthetic resin.

  The lid 12 made in the above structure is as shown in FIG. 2 when viewed from above, and as shown in FIG. 3 when viewed from the bottom or back. As shown in FIG. 1, the lid 12 is not easily detached from the cup when its cylindrical edge band portion 26 is engaged with a bead 22 formed at the opening end of the cup in an interference fit state. Attached to the open end of the cup.

  In order to eat the ice cream inside the ice cream container filled with ice cream in the state as shown in FIG. 1, when the lid 12 is removed from the cup 10, the lid 12 is turned over, and FIG. As shown, the lower end of the cup 10 may be fitted to the annular receiving surface 30. In the embodiment shown in FIGS. 1 to 3, the fitting between the annular receiving surface 30 and the lower end of the cup is to insert the lower end of the cup peripheral wall between the lips 38 and 40. Due to the fitting between the annular receiving surface and the lower end of the cup, the lid and the cup are firmly coupled by frictional engagement, and the lid is disposed in a state of being coupled integrally with the cup until eating of the ice cream is finished. In addition, while eating the ice cream, if the cup is supported by the lid portion, the finger does not directly touch the peripheral wall of the cup.
