The specific embodiment

Please refer to Fig. 1 and Fig. 2, in preferred embodiment of the present invention, cup of the present invention comprises a cup 10, and this cup 10 has an apical margin 20, a bottom surface 30, a lateral surface 40 and a medial surface, these apical margin 20 external diameters are greater than the external diameter of this bottom surface 30, make these cup 10 integral body be round table-like.Structure one accommodation space is enclosed with this medial surface in this bottom surface 30, and this accommodation space is in order to article-containing (as solution, shot-like particle etc.), and it is planar and be convenient to printing or pad pasting that this lateral surface 40 is smooth arc.This medial surface has multiple tracks protuberance extending longitudinally 51, and those protuberances 51 are arranged around this medial surface, between every two protuberances 51, are formed with depressed part extending longitudinally 52 one.The sum of preferably's protuberance 51 is between 45 to 60, and the sum of depressed part 52 is identical with the sum of protuberance 51.In the present embodiment, each protuberance 51 is convex arc shaped, and the curvature of each depressed part 52 equals the curvature of this lateral surface 40, and the structure outward appearance that each protuberance 51 and each depressed part 52 are formed is interrupted the wave of shape seemingly, as shown in Figures 6 and 7.In other embodiments, the curvature of each depressed part 52 also can be less than the curvature of this lateral surface 40, makes those depressed parts 52 be concave arc chamfering shape, and makes structure outward appearance that each protuberance 51 and each depressed part 52 form wave without stop seemingly.

Wherein, the top of the top of each protuberance 51 and each depressed part 52 joins and forms a ring top 53, and the bottom connection of the bottom of each protuberance 51 and each depressed part 52 forms a ring bottom 54.This medial surface is formed with two level and smooth annular cambered surfaces 55,55', wherein a level and smooth annular cambered surface 55 is located between this apical margin 20 and this ring top 53, as shown in Figure 2 and Figure 3, another level and smooth annular cambered surface 55' is located between this bottom surface 30 and this ring bottom 54, as shown in Fig. 2 and Fig. 5.

Wherein, the summit that the thickness of this bottom surface 30 is greater than each protuberance 51 is to the spacing between this lateral surface 40.

Wherein, this medial surface radial integrated protrudes at least one reinforced ribs 56.In the present embodiment, this reinforced ribs 56 one arcs extend and around this medial surface in the form of a ring, as shown in Figure 2.In other embodiments, this reinforced ribs 56 also can comprise several blocks, those blocks around and arc be spaced in this medial surface.This reinforced ribs 56 of preferably is coaxial with this cup 10, as shown in Figure 6.In addition, this reinforced ribs 56 is convex arc shaped, as shown in Fig. 2 and Fig. 4.

Wherein, this reinforced ribs 56 is separated into two material reducing blocks by least a portion protuberance 51 and at least a portion depressed part 52, in fact, the height of the visual cup 10 of the present invention arranges more than one reinforced ribs 56 in the appropriate location of the medial surface of cup 10, the actual quantity of this reinforced ribs 56 needs to meet following relationship: " diameter of ring bottom 54 is R; ring bottom 54 is H to the vertical height at ring top 53, and the integer part of the numerical value of H/R gained is N, and N is the actual quantity of reinforced ribs 56." a N reinforced ribs 56 is separated into N+1 material reducing block 57,57', 57'' by those protuberances 51 and those depressed parts 52 respectively; example is as shown in Figure 2; N equals at 2 o'clock; always have 56, two reinforced ribs 56 of two reinforced ribs those protuberances and those sunk parts are divided into three material reducing blocks 57,57', 57''.Preferably arranges a reinforced ribs 56 between this ring bottom 54 and this ring top 53 in per unit distance D, and wherein this unit distance D meets following relationship:

D-1≦H/（N+1）≦D+1。

By this, the present invention is due to self-assembling formation depressed part 52 between two adjacent protuberances 51, so this depressed part 52 needn't consume material, and must reduce material usage and overall weight.

Yet, in order to promote the overall construction intensity of the present invention after reducing material usage and overall weight, can set up reinforced ribs 56 and level and smooth annular cambered surface 55,55' at medial surface, reach the effect that promotes overall construction intensity of the present invention.

Importantly, the visual protuberance 51 of the present invention is accurately controlled the quantity of required reinforced ribs 56 with depressed part 52 actual distribution in the situation of medial surface, and enough reinforced ribs 56 can significantly promote overall construction intensity of the present invention and non-deformability, do not have the waste that too much reinforced ribs 56 is set and causes material, or very few reinforced ribs 56 is set and causes the problems such as structural strength deficiency of the present invention.

It is worth mentioning that, no matter be to only have single reinforced ribs 56 or have a plurality of reinforced ribs 56, meeting under the relation of D-1≤H/(N+1)≤D+1, the position at each reinforced ribs 56 places coordinates the position of two level and smooth annular cambered surfaces just can allow each material reducing block 57, 57', 57'''s is upper, lower both sides are all provided with and have the element of strengthening its structure, by this, each material reducing block 57, 57', 57'' can reduce under the situation of material usage and overall weight, still possess certain structural strength and non-deformability, do not have part-structure too fragile and easily break or be subject to external force to affect generation gross distortion.

In addition, the present invention also can thicken bottom surface 30 to summit that its thickness is greater than each protuberance 51 to the spacing between this lateral surface 40, and by this, the thickness of this bottom surface 30 is enough to bear external impact and reaches and be difficult for the effect broken.

Again, because reinforced ribs 56 is to be convex arc shaped, and the summit of reinforced ribs 56 is circular arc, and when a plurality of cup 10 heaps stack togather by this, reinforced ribs 56 can not remove the lateral surface 40 of each cup 10 of scratch.
