Description of the invention (1) Technical balance The present invention relates to a beverage can, such as an aluminum can or an iron can, which is generally made of metal, and is particularly suitable for the lid of such a beverage can. It contains an integrated sanitary can opener. The sanitary cover is installed on the top cover with a positioning member and is stored in a hygienic state when the lip container is covered. The lip contact portion of the top cover is shielded and the can open portion is formed through the reinforcement. Reliable top cover opening function. BACKGROUND OF THE INVENTION To open and take out a material tank made of metal, a lever-type can opener is usually provided on the top of the tank, which is positioned by a positioning element (such as a rivet) and can be pulled up along a preset pressure seam. An opening sheet is provided for the top cover to form a circular opening. The top cover of this type of tank is exposed, and it is used to define the lip contact part of the top cover which is easy to collect dust and other air impurities. When this easy-opening can is used, the lip contact part of the top cover contains unclean impurities, which is not good for human health. In order to overcome the above problems, the cans can be provided with a straw at the same time. However, the problem of this type of beverage cans containing straws is that it cannot cooperate with the mass production operation of the can body, so it is difficult to carry out a commercial mass production process. Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling this page). To solve this drawback of this kind of tin can, the inventor has provided a tin can with a sanitary lid, which is disclosed in U.S. Patent No. 5,813,559 and related Korean Patent No. 141618. This type of tank can be divided into three types, that is, the tank can-simultaneously have a sanitary cover device and a lever-type can opener, which can be installed in a rotatable manner on the top cover positioned by rivets, so as to cover Touch the lips of the cover. At the same time, the sanitary cap can also be integrated with a lever-type can opener mounted on the top cap. This sanitary cover can thus be switched between two positions, namely a sanitary cover position and a raised open position. In addition, the sanitary cover can be similar to the above 2nd paper size applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) 4495 6 8 A7 B7 5. Description of the invention (2) Types of structure and lever-type can openers are set to a single structure β In short, the third type of sanitary cover structure is provided with a U-shaped can opener near the riveted place, which is covered by the cover When the protection position is pulled up, the top cover can be effectively opened. The material tank with such a sanitary lid structure can fully and almost completely improve the hygiene problems of a typical material tank, but it still has the following disadvantages. That is, in the first type of grate tank structure, the sanitary cover and its lever-type can opener must be produced separately, and then the two are assembled with the top cover at the same time by rivets, which makes it difficult to commercialize mass production. Problems with tank structure. In addition, the use of separate sanitary lids and can openers ′ also increases production costs. Another problem with the first type of hopper structure is that the user operates the lid and the can opener. On the other hand, the problem with the structure of the second type of beverage can is that the sanitary cover made with the can opener must be turned from the sheltered position to the raised position before opening along the pressure seam, which is not only inconvenient for the user to operate At the same time, the incorrect rotation or pulling action of the sanitary cover may be generated. In the third type of hopper structure, the can opener formed integrally with the sanitary cover is provided with a cover that can be pulled when the top cover is pulled from the shielding position to the open position. Depress the can opening part of the top cover opening piece. However, the can-opening part does not have a structural reinforcing device, and thus has the disadvantage that it may not be able to effectively open the opening sheet along the preset seam. This sometimes causes consumers to be unable to open the coin end of the top cover. In addition, the sanitary cover disclosed in the above-mentioned U.S. patent completely covers the outer side of the joint cover peripheral edge. This structure causes manufacturing difficulties, and the work efficiency and throughput are also reduced. SUMMARY OF THE INVENTION In order to solve the problems of the above-mentioned conventional technology, the present invention is to provide a top cover of a tin can, which has an integrated sanitary cover, and the sanitary cover is set to be able to be pulled up from a shielding position by its can opening portion to open the top cover. , And a reinforcing device is provided in the can opening section, and at the same time, it has-a thumb-operable elastic dome sheet 'for thumb-pressing when it is pressed down 3 paper sizes, using China's standard house (CNS) A4 specifications (210X29? Mm) (please read the precautions on the back before filling in this page)-Packing. Order printed by the Central Government Bureau of the Ministry of Economic Affairs and Consumer Cooperatives 449568 A7 B7 V. Description of the invention (3) Flexible pull The sanitary cover part covering the top cover is lifted by the user, so the user can conveniently grasp and pull up the sanitary cover. The sanitary cover also has a reaction device for the elastic dome sheet to more effectively pull up the sanitary cover when the thumb is pressed down; this sanitary cover is also set to improve the troubles of the production process, so that the material tank can be effectively commercialized. Mass production. In order to achieve the purpose of disclosure, the present invention provides a top lid of a tin can, which has a can opening portion integrally formed with a sanitary lid. The sanitary cover is connected to the top cover by a positioning member, and is set to extend to the joint periphery of the hopper or the inner wall of the perimeter of the hopper, or to cover the periphery of the top cover opening sheet defined by the seam. The sanitary cover has an elastic dome sheet which can be controlled by the thumb, so that the round finger can be elastically pulled up by pressing the thumb. The elastic dome sheet has a semicircular shape or other shapes, or an angular shape such as a semicircular shape. In order for the dome sheet to have a reliable elastic reaction force, a reaction device is formed on the periphery of the dome sheet. The reaction device as an elastic dome sheet includes a reaction outer periphery formed at the outer end of the dome sheet *, a reaction slit is formed at the top of the dome sheet 'or a reaction end is formed at the top of the dome sheet. A can-opening part can be pushed down along the seam when the sanitary cover is pulled up and opened the opening sheet. The can-opening part is set on the sanitary cover with a slit in the middle of the positioning member and the dome sheet. The sanitary cap also has a reinforcing device for improving the strength of the can opening portion, so that the can opening portion can more effectively open the opening along the seam without risk of failure. In order to open and use the elastic dome with the sanitary lid, when the sanitary lid is not opened, press down with your thumb. When the dome sheet is pressed down, the shield portion of the sanitary cover can be lifted off the top cover due to the reaction force of the dome sheet. The user can thus conveniently grasp the sanitary lid when pulling up the sanitary lid to depress the opening sheet by the can opening portion. When the sanitary lid is pulled up as before, the 'opening part' presses down the opening sheet in the reverse direction so as to be opened along the pressure seam. The can opening part is provided with a reinforcing device such as a reinforcing rib, which has a first bent and compacted rectangular cross-section; a second reinforcing rib has an arc-shaped cross-section, or a total folded shape to increase its strength . This allows the can opening portion to reliably open the opening piece along the seam, and does not fail due to the internal pressure acting on the opening piece. 4 This paper is suitable for Chinese Hakka sample rate (CNS) 8 4 Lin (210X297 mm) ---------- ^ ------.

The can section 13 is particularly suitable for use with a high-pressure and high tensile strength can opener. Fig. 15 shows another reinforcing device used for the can open section. In this embodiment, the can open section 13 is flat. Before pressing, it is pulled up along its central axis to form a reinforcing rib with double folds 13e at the ends. Each fold 13e is bent at the end 13g, and then bent a second time at the other end 13h to form a double break. Compared with the single-folded ribs, the double-folded ribs can improve the strength of the can opener 13 and are suitable for high-pressure concrete tanks.. The recessed slit 24 is shown in Figure 16 on the sanitary cover. A U-shaped can opening portion 13 is defined on 8 and is provided at the intermediate position between the positioning member 3 of the sanitary cover 8 and the dome sheet 6. The slit 24 can be completely cut for the sanitary cover 8 to open the opening sheet along the pressure seam 3C. At 3a, a reliable can opening portion 13 is formed. The slit 24 can also be recessed and does not need to be completely cut to form a recess for the lip contact area around the lid opening piece 3a. It is hygienic when storing the cans. In addition, the 'cut seam 24' can also be pressed on the lower surface of the sanitary cover 8 to form an inverted V-shaped section, and it can also be pressed on the sanitary cover. 8 on the upper surface to form a V-shaped section facing upwards. All the seams 24 can also be U-shaped or other U-shaped repairs. 13 This paper size is applicable to Chinese literary standards (〇 «) person 4 specifications (210 father 297 male) & ≫ (Please read the notes on the back before filling in this education) • Packing.

Description of the invention (1: 3) decorated outside Since the sanitary cover 8 is rolled into a round or smooth outer end to prevent the user's fingers from being accidentally injured, the concave curved line 10 of the sanitary cover 8 may not be easily bent when the rolled end edge of the sanitary cover 8 is pulled up. The problem is that the concave curved line 10 can be partially cut at the outer end of the rolling during the manufacturing process of the material tank. This allows the sanitary cover 8 to be bent along the concave curved line 10 when the opening piece 3a is pulled up. As shown in FIG. 17, the elastic dome sheet 6 can be used in a conventional can opener or a conventional can opener, and can be connected to the top using a positioning device in the joint manner of the sanitary cover 8 according to the present invention. Cover, but does not completely cover the opening D piece 3a. That is, the dome sheet 6 is formed between the upper and outer end edges 103 and the arc-shaped seam 104 above the can opener 101. When the elastic dome sheet 6 is pressed down with a thumb, the can opener 101 is popped up and separated from the top cover 50 due to the reaction force of the dome sheet 6, so that the user can conveniently grasp the can opener 101 for depression. Opening sheet 3a. The dome sheet 6 described above may also be provided with a flat top surface, one end portion and an inclined surface, or a concave top surface as shown in 18a to 18d. The dome sheet 6 may also have a hemispherical shape as shown in Fig. 18e or other shapes modified by a hemispherical shape. Of course, the flat top surface, end, inclined surface or concave top surface, hemispherical or other hemispherical shape of the dome sheet 6 of the present invention are all for improving the elastic reaction force of the round sheet 6 and matching the type of the material tank. And pressure to form a suitable reaction force. As shown in the figures from 18h to 18g, the round top sheet 6 can be set in various regular or irregular shapes to make it more stable and reliable. The can opener 101 can also be freely determined in accordance with the size and shape of the canister as shown in Figs. 19a to 19e. In addition, the outer end edge 103 of the can opener 101 can be arc-shaped as required. The dome sheet 6 may also be provided with a reaction peripheral edge 6a such as that on the sanitary cover 8, or these reaction peripheral edges 6a may be omitted as shown in Figs. 20a to 20d. The can opener 101 with the elastic dome sheet 6 can be rotatably connected to a can lid 50, so that the can opener 101 is normally above the opening sheet 3a to cover the opening sheet 3a, and can be turned to the pulled-up position The opening piece 3a is opened along the pressure seam 3c. 14 This paper size applies to the Chinese National Standard (CNS) A4 (210X297 male 4) Please read the memorandum before binding to the Central Government Bureau of the Ministry of Economic Affairs employee consumer cooperative printing 4495 6 8 at B7 V. Description of the invention (14 ) Industrial utilization As mentioned above, the present invention provides a top lid of a hopper, which has an integrated sanitary cover. This sanitary cover is set to cover the periphery of the opening sheet which is limited to the top cover by crimping. It is used to protect the lip contact area from impurities in the air when the material is stored. The sanitary cover has a reinforced can opening portion, which can be depressed when the sanitary cover is pulled up and opens the opening sheet along the pressure seam. The can portion with a reinforcing device can improve the strength of the can opening portion so that it can act even under high pressure. When the inner surface of the opening sheet, the opening sheet can still be reliably opened. Therefore, the sanitary cap becomes a can-opening type when the can is opened. The shape and arrangement of the reinforcing device of the present invention can be changed freely according to the design condition of the material tank, the pressure acting on the opening sheet and the size of the tank body. The elastic dome sheet of the present invention is preferably used for a lever-type can opener conventionally connected to a top cover. In this way, the can opener can be popped up when the dome sheet is pressed by the thumb, so the user can conveniently grasp the can opener to open the top lid of the can. Although the present invention discloses a preferred embodiment for the purpose of illustration, various modifications, possible additions and deletions that can be made by a person skilled in the art should still be regarded as not departing from the scope of the following patent application of the present invention and spirit.
