Technical Field
[0001] 0001. This invention relates to a packaging container, and more particularly to an easy-open can. Background Technology
[0002] 0002. The same inventor of this application previously applied for a low-cost hygienic aluminum can that is easy to reseal, with application number 2023105445316 and application date of May 14, 2023. It has an outwardly protruding wrench part and an outwardly extending anti-reverse piece integrally formed on the edge of the flip-top. In the subsequent actual production and use process, the inventor found that the aluminum can has shortcomings. First, the wrench part and anti-reverse piece protrude outward, which puts high requirements on the mold and production. Second, during packaging and transportation, the wrench part is easy to be hit, causing local cracking of the circumferential tear line. This application is to further improve the existing problems, reduce the difficulty of mold and production, and avoid the problem of local cracking of the circumferential tear line.
[0003] 0003. In addition, when users drink directly, their mouths will touch the top and sides of the can. The above application solves the hygiene problem of the top of the can, but does not solve the hygiene problem of the sides of the can. Summary of the Invention
[0004] 0004. In order to overcome the shortcomings of the prior art, the present invention provides a flip-top sanitary easy-open can with low production cost, suitable for widespread application, and convenient secondary sealing with the advantages of hygiene and secondary sealing.
[0005] 0005. The technical solution adopted by the present invention to solve its technical problem is: A convenient flip-top sanitary can for secondary sealing is provided. The top of the can has a pull-out part connected to a pull ring. When the pull-out part is pulled open, it forms a water outlet. An integrally formed can lid is installed on the top of the can. The can lid has a downwardly extending connecting part. The upper part of the connecting part has an opening with a circumferential tear line. The upper part of the circumferential tear line forms a flip-top. The can also include a cover that covers the part of the can side wall that can be touched by the mouth when drinking.
[0006] 0006. The covering is a protective film, with the upper part of the covering attached to the flip-top and the lower part attached to the side wall of the can that can be touched by the mouth.
[0007] 0007. The cover is integrally formed with the can lid. The lower end of the cover is connected to the connecting part, and the upper part is a free end. The upper end of the cover is provided with a fastening part for fastening the flip lid. After the cover fastens the flip lid, the part of the side wall of the can that can be touched by the mouth is covered by the cover.
[0008] 0008. The top edge of the flip cover is provided with a raised ring that conforms to the raised shape of the top of the can, and the fastening part is an arc-shaped bend that conforms to the shape of the raised ring.
[0009] 0009. A connecting piece is formed by extending a portion of the lower end of the connecting part downward, and the lower end of the connecting piece is connected to the lower end of the covering member.
[0010] 0010. The circumferential tear line has a downward bend at the location corresponding to the water outlet, and the portion within the bend forms a wrench-shaped portion.
[0011] 0011. The connecting part is provided with a handle cutout located below the bending part.
[0012] 0012. The flip cover is provided with an integrally formed pleated part whose shape is adapted to the shape of the water outlet. The inside of the pleated part is a pressing part.

[0013] 0013. The two ends of the circumferential tear line are bent downward to form a longitudinal tear section, and the part between the two longitudinal tear sections forms a hanging strap connecting the connecting part and the flip cover.
[0014] 0014. The hanging cover is provided with an upward-opening perforated strip, and the part inside the perforated strip forms a counter-plate. After the flip cover is opened, the front end of the counter-plate abuts against the surface of the can. The reaction force between the counter-plate and the can causes the counter-plate and the can to form an acute angle for force retention.
[0015] 0015. The hanging cover is provided with an H-shaped cutout, so that the flip cover forms a downwardly extending anti-reflective piece at the H-shaped cutout, and the connecting part forms an upwardly extending blocking piece at the H-shaped cutout. After the flip cover is opened, the upper end of the blocking piece abuts against the anti-reflective piece, so that the blocking piece and the anti-reflective piece form an acute angle for force retention.
[0016] 0016. The beneficial effects of the present invention are: the present invention provides a cover on the part of the side wall of the can that can be touched by the mouth when drinking. When not opened, the cover covers the part of the side wall of the can that can be touched by the mouth. When drinking, the cover is torn or opened to ensure that the part of the side wall of the can that can be touched by the mouth is hygienic.
[0017] 0017. In addition, the wrench part and the anti-reverse piece of the present invention are close to the side wall of the can and do not protrude outward, which reduces the difficulty of molding and production and avoids the problem of local cracking of the circumferential tear line.

Implementation
[0020] 0020.Reference Figures 1 to 6 A convenient flip-top hygienic aluminum can with secondary sealing is disclosed. The can 1 has a pull-out part 2 at the top, which is connected to a pull ring 3. When the pull-out part 2 is pulled open, it forms a water outlet. The top of the can 1 is fitted with an integrally formed can lid 4. The can lid 4 has a downwardly extending connecting part 40. The upper part of the connecting part 40 is provided with an open circumferential tear line 41. The upper part of the circumferential tear line 41 forms a flip-top 42 (the structure and function of the flip-top are the same as those described in application document 2023105445316). The can also includes a cover 7 that covers the part of the side wall of the can 1 that can be touched by the mouth when drinking. When not opened, the cover 7 blocks the part of the side wall of the can that can be touched by the mouth. When drinking, the cover 7 is torn or opened to ensure that the part of the side wall of the can that can be touched by the mouth is hygienic.
[0021] 0021. See the appendix to the instruction manual. Figure 3 The cover 7 is a protective film, which is a flexible film and is separate from the can lid 4. The upper part of the cover is attached to the flip lid 42, and the lower part is attached to the side wall of the can 1 that can be touched by the mouth. When the cover 7 is a protective film, the lower end is the tear-off part. It can be pasted to the side wall of the can 1 by adhesive, electrostatic adsorption, or adhesion. The upper part of the protective film should be firmly connected to the flip lid 42, which can be done by adhesive, heat fusion, or other methods. When drinking, the lower part of the cover 7 is torn off. After drinking, the protective film can be pulled back to cover the side wall of the can 1 that can be touched by the mouth, ensuring that the side wall of the can that can be touched by the mouth is hygienic.
[0022] 0022.Reference Figure 1 , Figure 2 , Figure 4 The cover 7 and the can lid 4 are integrally formed by vacuum forming or injection molding. The lower end of the cover is connected to the connecting part 40, and the upper part is a free end. The upper end of the cover is provided with a fastening part 70 for fastening the flip lid 42. After the cover fastens the flip lid 42, the part of the side wall of the can 1 that can be touched by the mouth is covered by the cover. The connection part between the cover and the connecting part 40 is suitable to be provided with a dotted line cut or a folded groove, so that the connection part between the cover and the connecting part 40 has no elasticity or only slight elasticity, to prevent the cover from being popped open.
[0023] 0023. The top edge of the flip cover 42 is provided with a raised ring 8 that conforms to the raised shape of the top of the can 1. The fastening part 70 is an arc-shaped bend that conforms to the shape of the raised ring 8. The fastening part 70 may only contact the bottom and part of the side wall of the raised ring 8, or it may contact part of the side wall and the top of the raised ring 8, or it may contact the bottom, side wall and the top of the raised ring 8. When the fastening part 70 only contacts the bottom and part of the side wall of the raised ring 8, the cover 7 will be compressed and slightly deformed, and the raised ring 8 will exert a downward force on the fastening part 70, causing the raised ring 8 to lock the fastening part 70. When the cover 7 contacts part of the side wall and the top of the raised ring 8, or contacts the bottom, side wall and the top of the raised ring 8, the top of the raised ring 8 will exert an upward force on the fastening part 70. At this time, the cover 7 is slightly stretched, or the fastening part 70 is slightly stretched and deformed, causing the raised ring 8 to lock the fastening part 70.
[0024] 0024. A connecting piece 401 is formed by extending a portion of the lower end of the connecting part 40 downward. The lower end of the connecting piece 401 is connected to the lower end of the cover. The connecting piece 401 can reduce the height of the connecting part 40 and save raw materials.
[0025] 0025. The circumferential tear line 41 has a downward bend 410 corresponding to the water outlet. A wrench portion 46 is formed within the bend 410. The circumferential tear lines on the lower and side edges of the wrench portion 46 are preferably continuous to facilitate prying up the wrench portion 46. Additionally, referring to… Figure 4 Preferably, the connecting part 40 is provided with a handle cutout 411 located below the bending part 410, so that a finger or nail can be inserted into the handle cutout 411 to easily pry up the handle part 46 and then lift it up to open the flip cover.
[0026] 0026. The flip cover 42 is provided with an integrally formed pleated part 5 whose shape is adapted to the shape of the water outlet. The interior of the pleated part 5 is a pressing part 6. After the pull-open part 2 is pulled open, the pressing part 6 is pressed down, and the pleated part 5 is stretched and deformed to form a sealing plug that is inserted into the water outlet. The structure and function of the pleated part 5 are the same as those described in the application document 2023105445316.
[0027] 0027.Reference Figure 5 , Figure 6 The two ends of the circumferential tear line 41 are bent downward to form longitudinal tear portions 44, and the portion between the two longitudinal tear portions 44 forms a hanging cover strap 45 that connects the connecting portion 40 and the flip cover 42, so as to realize the hanging cover function after opening.
[0028] 0028. The first structure that keeps the flip cover in place is as follows: Figure 5 As shown, the hanging cover 45 is provided with an upward-opening perforated strip 47. The portion inside the perforated strip 47 forms a counter-plate 49. After the flip cover 42 is opened, the front end of the counter-plate 49 abuts against the surface of the can 1. The reaction force between the counter-plate 49 and the can 1 causes the counter-plate 49 and the can 1 to form a force-holding acute angle.
[0029] 0029. A second structure that keeps the flip cover in place, such as... Figure 6 As shown, the hanging cover 45 is provided with an H-shaped cutout 450, so that the flip cover 42 forms a downwardly extending anti-reflective piece 49 at the part of the H-shaped cutout 450, and the connecting part 40 forms an upwardly extending blocking piece 48 at the part of the H-shaped cutout 450. After the flip cover 42 is opened, the upper end of the blocking piece 48 abuts against the anti-reflective piece 49, so that the blocking piece 48 and the anti-reflective piece 49 form a force-holding acute angle.
[0030] 0030. The wrench part and the anti-reverse piece of the present invention are closely attached to the side wall of the can and do not protrude outward, which reduces the difficulty of molding and production and avoids the problem of local cracking of the circumferential tear line.
[0031] 0031. The above embodiments do not limit the scope of protection of this invention. All equivalent modifications and variations made by those skilled in the art without departing from the overall concept of this invention shall still fall within the scope of this invention.
