Description

  The present invention relates to a cup in which an upper cup fits into an inner space of a lower cup and can be stacked.

  A cup is a cylindrical vessel with an opening at the top for drinking water. There are many different forms, and the material is made of glass or plastic. Sometimes it is made of metal such as stainless steel. FIG. 3 shows a conventional general cup, which has a cylindrical shape in which a side (b) rises from the periphery of a circular bottom (b) and an upper end is opened, and the side (b) Is inclined so that the upper outer diameter becomes larger.

  Some cups have a cylindrical shape that stands vertically with respect to the bottom (b) without tilting the side (b). However, as shown in FIG. It becomes easy to drink drinking water. On the other hand, when not in use, they are stacked and accommodated in the cupboard, but by making the side part (b) inclined, the upper cup can be stably stacked with its lower end fitted into the internal space. . In addition, there is an advantage that the stacking height is lowered. In contrast, a complete cylindrical cup with the same outer diameter can be stacked with the bottom of the upper cup resting on the upper end of the lower cup, but it is not stable and the stacking height increases.

  FIG. 3 shows a case where two cups are stacked. In this way, the upper cup fits into the inner space (c) of the lower cup and is stacked, so the side outer peripheral surface (d) of the upper cup is the side inner peripheral surface (e) of the lower cup. Close contact with. Sometimes it bites in and becomes difficult to separate. As a result, fine scratches are generated on the outer peripheral surface (d) and the inner peripheral surface (e) of the side part (b). Sometimes the upper cup bites too much and the side of the lower cup breaks.

  In particular, a plastic cup with low hardness makes a transparent plastic cup dull due to fine scratches generated on the outer peripheral surface (d) and the inner peripheral surface (e) of the side (b). By the way, conventionally, there has been known a cup having a configuration in which no scratch is generated on the inner peripheral surface and the outer peripheral surface of the side portion when a plurality of cups are stacked.

The “cup” according to Japanese Patent Application Laid-Open No. 2010-35972 prevents the outer walls from coming into contact with each other when two or more cups are stacked, and the outer wall is scratched or the outer wall is cracked. To prevent.
The cup includes a disk-shaped bottom, an outer wall that rises from the outer peripheral edge of the bottom, and an engagement protrusion that rises from the inner peripheral edge of the bottom. The outer wall is formed in the shape of a truncated cone that extends toward the upper part, and the engaging projection is formed in the shape of a truncated cone that contracts toward the upper part. The thickness of the engaging projection is set to be thinner than the thickness of the bottom and thicker than the thickness of the outer wall. The inclination angle of the engaging protrusion is set larger than the inclination angle of the outer wall. For this reason, when two cups are overlapped with each other by engaging their respective engaging projections, a gap is formed between the respective outer walls so that they do not contact each other.

The “cup” according to Japanese Patent Application Laid-Open No. 2007-195785 is a cup that causes rich foaming when beer or the like is poured without being damaged by sandblasting or laser.
Therefore, either a brush or a brush is used to form a substantially concentric ring or a spiral band from the inner bottom surface of the cup toward the opening, and a part of the inner surface of the cup is made of thermosetting resin. A resin film layer is formed by applying a certain polyurethane resin, the layer thickness of the resin film layer is set to 1 to 50 μm, and pores are developed in the resin film layer so that pores having a pore diameter of 1 to 50 μm are 1 mm ^2. It is assumed that 500 to 20000 pieces exist.

  Thus, there are cups that prevent the outer peripheral surface and inner peripheral surface of the side portion from being scratched when a plurality of cups are stacked. The cup according to the present invention also prevents the generation of scratches and has the same purpose, but provides a cup that is simpler and has a different form.

  The cup according to the present invention has a cylindrical shape in which the side portion stands on the outer periphery of the circular bottom portion, and the side portion is inclined so that the outer diameter on the upper side is increased. That is, the basic form is a cup as shown in FIG. 3, and for this purpose, the upper cup can be fitted and stacked in the internal space of the lower cup. The material is generally made of plastic but is not limited.

  By the way, the cup of this invention protrudes the convex piece used as a support to the internal peripheral surface of a side part. The convex pieces are provided in at least three places, and the pitch between the convex pieces is equal. This convex piece is provided at a position where the bottom portion hits when the upper cup fits into the internal space, and the side outer peripheral surface is not in contact with the side inner peripheral surface of the lower cup. However, this convex piece is one form of the support on which the bottom of the upper cup is placed, and the specific shape is not limited.

  The cup according to the present invention has a cylindrical shape whose side portion is inclined so that the outer diameter of the upper side becomes larger. For this reason, a plurality of cups can be fitted and stacked in the inner space of the lower cup. And the convex piece used as a support protrudes in several places with sufficient balance on the internal peripheral surface of a side part, and the bottom part of the upper side cup which fits in interior space is mounted on the said convex piece for that purpose. Therefore, the side outer peripheral surface of the upper cup does not contact the side inner peripheral surface of the lower cup, and the side outer peripheral surface and the inner peripheral surface are not damaged. For this reason, a highly transparent cup is maintained forever. Of course, the upper cup is not strongly fitted into the lower cup and the side portion is not broken.

It is an Example which shows the cup which concerns on this invention, (a) is a top view, (b) is AA sectional drawing of (a). Example when two cups are stacked. Conventional general cup. When two conventional cups are stacked.

  FIG. 1 shows an embodiment of a cup according to the present invention. In FIG. 1, reference numeral 1 denotes a bottom portion, 2 denotes a side portion, and the side portion 2 forms a cylindrical shape inclined to the outer periphery of the bottom portion 1. . The inner space 3 surrounded by the side part 2 has a larger upper inner diameter, so that the upper cup can fit into the inner space 3 of the lower cup and be stacked. The cup may be made of any material, but is generally made of plastic and injection molded.

  .. Are formed at three locations on the bottom side of the inner peripheral surface 4 of the side portion 2, and the convex pieces 5, 5... Protrude from the inner peripheral surface 4. The convex pieces 5, 5... Serve as a support for the upper cup fitted in the internal space 3, and the bottom 1 of the upper cup is placed thereon. And when there is no convex piece 5,5 ..., if an upper cup fits in the internal space 3, the side part outer peripheral surface 6 will contact the side part inner peripheral surface 4 of a lower cup, but a bottom part The outer peripheral surface 6 does not contact the inner peripheral surface 4 because 1 is placed on the convex pieces 5, 5.

  FIG. 2 shows a case where two cups are stacked. The upper cup B is fitted and stacked in the inner space 3 of the lower cup A, and the bottom 1 of the upper cup B is placed on the convex pieces 5, 5... Protruding on the side inner peripheral surface 4 of the lower cup A. . A slight gap 7 is formed between the side inner peripheral surface 4 of the lower cup A and the side outer peripheral surface 6 of the upper cup B. That is, the outer peripheral surface 6 and the inner peripheral surface 4 are supported by being placed on the convex pieces 5, 5.

  By the way, the support formed on the inner peripheral surface 4 of the side portion 2 and on which the upper cup B is placed is not limited to the convex pieces 5, 5. If the cup is injection-molded using plastic as a material, the convex pieces 5, 5... Formed on the inner peripheral surface 4 of the side portion 2 are preferably elongated and extend to the bottom portion 1. However, the shape may be hemispherical as long as it is a convex piece 5, 5... For simply supporting the upper cup B.

  Moreover, it is also possible to form a ring-shaped support formed over the entire circumference of the side inner peripheral surface 4. However, when drinking drinking water contained in a cup, if a continuous ring is formed around the entire circumference, the cross-sectional shape must be such that the drinking water is not blocked by the ring-shaped support (smoothly flows). .
