As shown in FIG. 1, a method S100 for manufacturing a cup having a cup bottom printing layer of the present embodiment includes the steps of: providing a substrate (step S10); forming a cup bottom printing layer (step S20); forming a first a protective film (step S30); forming a cup bottom (step S40); and forming a cup (step S50).

As shown in FIG. 1 and FIG. 2, a substrate is provided (step S10), wherein the substrate 10 has a first surface 11, and the first surface 11 has a plurality of specific regions 12 and a plurality of positioning patterns 20, The positioning patterns 20 correspond to the specific regions 12 one-to-one.

The substrate 10 as shown in FIG. 2 may be a paper substrate 10 or a plastic substrate 10 or a silicone substrate 10 or a rubber substrate 10. Each of the specific regions 12 can be a circular area, and each of the positioning patterns 20 can be an positioning point, a positioning cross or a positioning symbol.

Further, providing a substrate (step S10) provides the substrate 10 to a cup automatic production machine for automated production of the cup 300 having the cup bottom printing layer 30 in a rapid and mass production line.

As shown in FIGS. 1 and 3, a cup bottom printing layer is formed (step S20), which is printed in each specific area 12 to form a bottom printing layer 30. among them Forming the bottom printing layer (step S20) may refer to each of the positioning patterns 20, and print or paste the characters or patterns or characters and patterns on each of the corresponding specific regions 12, and the printed characters or patterns or characters and patterns. The system can be defined within a particular area 12.

As shown in FIG. 1 , FIG. 4A and FIG. 4B , a first protective film is formed (step S30 ), which is formed on the first surface 11 of the substrate 10 to form a shower film 40, and the shower film 40 is covered and sealed. The first surface 11 and the first protective film 50 are formed on the bottom printing layer 30 by the coating 40.

That is, the first protective film 50 can be formed substantially by the shower film 40, completely covering each of the specific regions 12 and the bottom printing layer 30 printed in the specific region 12, and isolating the aqueous substance of the bottom printing layer 30, Oily or volatile substances.

Thus, the printing ink or printing material of the letter or pattern of the bottom printing layer 30 can be covered by the first protective film 50 and covered between the first protective film 50 and the first surface 11 of the substrate 10. In order to make the pattern or the characters or patterns and characters formed by the bottom printing layer 30 completely and clearly present, the coating 40 used to form the first protective film 50 may be formed of a transparent substance.

When it is required to be used in contact with a specific liquid article (such as instant noodles, coffee, hot drinks, urine, etc.), the material of the coating 40 can be selected such as polyethylene (PE, polyethylene), polypropylene (PP, Various thermoplastics such as polypropylene, polyethylene terephthalate or PLA (polylactic acid) which are easy to manufacture, inexpensive, and transparent. Among them, polylactic acid (PLA, Polylactic acid) is an environmentally friendly material made of corn, which can be completely decomposed by microorganisms in nature, and finally produces carbon dioxide and water. It will not pollute the environment.

As shown in FIGS. 1 and 5, a cup bottom is formed (step S40), which presses the specific regions 12 and forms a plurality of cup bottoms 100, wherein each cup bottom 100 has a first protection The film 50 covers one of the bottom printed layers 30.

Forming a cup bottom (step S40) for stamping, pressing the substrate 10 from the specific regions 12 with a punching tool, and pressing each of the specific regions 12 with the positioning patterns 20 as reference points to form A plurality of cup bottoms 100. The cup bottom 100 formed may also be formed as a circular cup bottom 100.

As shown in FIG. 1 , FIG. 6 and FIG. 7 , a cup body is formed (step S50 ), in which each cup bottom 100 is in close contact with a cup body 200 to form a cup body 300 , and any one of the cup bottoms 100 is closely connected. A cup 200 and its bottom printed layer 30 are located inside the formed cup 300. That is, the cup bottom 100 and the cup 200 together form a cup 300 that can be used as a container, and the bottom printing layer 30 is located inside the formed cup 300.

Please refer to the cup body 200 as shown in Fig. 6 and Fig. 7, which is made of the same material as the base material 10 or made of paper or plastic or silicone or rubber or styrofoam. Material. The cup body 300 formed by the cup bottom 100 and the cup body 200 may also be a disposable cup body 300, such as a disposable paper cup, a disposable bowl or a disposable plastic cup.

Another example, the cup 300 shown in FIG. 7 can be filled with liquid, solid, or liquid solid, or can be hot or ice or room temperature, such as water, beverage, coffee. There are no specific restrictions on instant noodles, congee, and snacks. And the material of the cup body 300, that is, the material of the cup bottom 100 and the cup body 200, can be selected as a material which does not deform or dissolve or damage when the object is filled. Made for manufacturing.

As shown in FIG. 8 , a method S200 for manufacturing a cup having a cup bottom printing layer according to the embodiment is a method for manufacturing a cup body having a cup bottom printing layer as needed for medical use or other applications. S100 adds two steps: printing the inner surface of the cup body (step S41) and forming a second protective film (step 42), performing printing on the inner surface of the cup body (step S41) and forming a second protective film (step 42). The inner surface of each cup 200 is printed with a letter or pattern or a scale pattern 60, and the inner surface of the printed cup 200 is covered with a second protective film 70.

As shown in FIG. 9, the cup 400 manufactured by printing the inner surface of the cup (step S41) and forming the second protective film (step 42) is added, and printing is performed on the inner surface of the cup or the pattern or the scale pattern 60. And covered with the second protective film 70, the contents of the cup 400 can be prevented from being contaminated by the characters or patterns or the scale pattern 60 printed on the inner surface of the cup body, and the medical industry is particularly wide. Applications.

The material of the second protective film 70 as shown in FIG. 9 may also be polyethylene (PE), polypropylene (polypropylene), polyethylene terephthalate (PET) or polylactic acid. (PLA, Polylactic acid).

In summary, it can be seen from the above embodiments that the cup 300 manufactured by the method S100 for manufacturing a cup having a cup bottom printing layer or the method for manufacturing a cup having a cup bottom printing layer is manufactured by the method S200. The cups 400 all have the following progressive characteristics: easy to manufacture and low in cost; the texture and the use of the cup 300 or the cup 400 can be more enriched, which greatly increases the consumer's use of the cup 300 or the cup 400.
