Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, and in particular to a can straw set. Background Technology

[0002] In daily life, it's common to drink beverages by inserting a straw directly into an aluminum can, such as when dining in a restaurant or traveling. This method avoids direct contact between the mouth and the outer edge of the can, ensuring hygiene, and allows drinking without having to lift the entire can, making it convenient. However, with increasing convenience, some problems have also arisen. For example, once the pull tab is opened, the drinking opening is relatively large, making it easy for dust to enter if the beverage isn't finished at once. Although existing technologies offer many solutions for dust prevention by adding a lid to the can, such as:

[0003] Chinese utility model patent (CN202953246U) discloses a reusable can lid structure. The can lid has an opening with a tear-indentation, and the part inside the tear-indentation constitutes a pull ring component. The can lid has a recess for the pull ring component to be pulled open and hidden. The pulled ring can be bent and placed in the recess to hide it. When drinking, the edge of the pull ring will not hurt the drinker. When it is necessary to reseal, the pull ring can be folded outward and pressed back to the original opening, thereby achieving a sealing effect.

[0004] Chinese utility model patent (CN203958912U) discloses a resealable can lid, which can be sealed by the elastic locking groove and elastic locking protrusion on the upper surface of the can after the can opening is opened, so as to achieve a resealable can opening.

[0005] Chinese utility model patent (CN204078366U) discloses a reusable sealing cap for aluminum cans. It features a first annular groove on the inner wall of the cap that mates with the flange at the top of the can. A medical rubber gasket is located on the top inner wall of the cap, corresponding to the can opening, to seal the can opening. A second annular groove on the outer wall of the medical rubber gasket mates with the edge of the can opening. A third annular groove on the outer wall of the cap prevents the remaining beverage from spoiling or dust from contaminating it after the can is opened and cannot be resealed.

[0006] Although the above solutions can all achieve the sealing of the opening of the can, a straw is still required separately, which is inconvenient. In order to solve this problem;

[0007] Chinese utility model patent (CN111284902A) discloses an aluminum can with a straw. The aluminum can has a straw at the pull ring. When drinking, the straw cap is opened and the pull ring is pulled, so the beverage in the can can be drunk with the straw. It is convenient and hygienic. Since aluminum can production has a standard production line, if such an aluminum can with a built-in straw is to be produced, the mold needs to be made again, which is costly. In addition, due to the structure of the straw, multiple aluminum cans cannot be stacked, which is inconvenient for storage and transportation.

[0008] In summary, although combining straws and lids on aluminum cans still presents the following problems: for example, the uncertainty of the usage scenarios when used outdoors, or the habit of tilting the straw to avoid excessive bending of the head when using it, which can easily cause the lid to fall off, and the inconvenience of storage and carrying, making it impossible to reuse.

[0009] Therefore, there is a need for a can straw set that is easy to store, carry, and reuse, and that has a better installation and fixing effect with the can, in order to meet the user's habit of drinking with a straw. Summary of the Invention

[0010] The purpose of this invention is to provide a can straw set that solves the problems of existing straw-equipped can lids being easy to fall off, inconvenient to store and carry, and not being reusable.

[0011] To address the above issues and overcome the shortcomings of existing technologies, this invention provides a can straw set, comprising a straw base and a straw cap that fit together. The straw cap includes a cap body with a fixing opening on its top surface for securing the straw. The straw extends into the can through the fixing opening. The bottom of the cap body is open. A locking area is formed on the circumferential inner surface of the cap body for detachably connecting the cap body to the neck of the can. A wrapping and fixing area is formed around the bottom end of the locking area of ​​the cap body for embracing the can body and folding over to cover the straw cap. An insertion area is formed on the outer circumferential surface of the cap body for detachable connection with the snap-fit ​​area of ​​the straw base.

[0012] The straw holder includes a base, the top of which is open to form a receiving area for loading the bottom of an aluminum can, and the inner circumferential surface of the base opposite to the insertion area forms the fastening area.

[0013] More preferably, the outer peripheral surface of the straw is formed with a positioning flange, the positioning flange is detachably snapped into the fixing port, and the straw has a first position and a second position;

[0014] In the first position, the straw extends downward into the interior of the can via the fixing port; in the second position, the straw is fixed to the fixing port by the positioning flange and is located on one side of the lid.

[0015] Compared with existing technologies, the can straw set of this invention, through the flexible fitting of the straw base and straw cap, makes storing the straw cap more convenient and allows for quick and secure installation of the straw cap with the straw onto the can. Furthermore, with the further cooperation of the locking area, wrapping and fixing area, insertion area, receiving area, and fastening area, the unfolded straw cap and straw base can be flexibly adjusted to fit according to usage needs. This ensures that users' drinking habits are met while also allowing for timely sealing and temporary storage of the can. The various combination options also facilitate storage and carrying, enabling repeated use and offering greater flexibility. Moreover, when the straw is in the second position (horizontal storage) and the wrapping and fixing area is folded, the fastening of the base provides a secondary sealing effect to prevent dust and slippage.

[0016] The present invention also provides a straw cap for an aluminum can, comprising a cap body, wherein the bottom of the cap body is open and the top surface has a fixing opening for fixing a straw, the straw extending into the interior of the aluminum can through the fixing opening, wherein the cap body comprises:

[0017] The locking area is formed on the circumferential inner surface of the lid, and its shape is adapted to the outer edge of the top of the can and can be detachably connected to the outer edge of the top of the can.

[0018] The wrapping and fixing area is softly connected at one end to the end of the clamping area away from the top surface of the lid. The wrapping and fixing area is used to extend and wrap the outer wall surface of the can extending downward from the top outer edge of the can.

[0019] The insertion area is formed on the outer peripheral surface of the cover, and the insertion area and the fastening area of ​​the seat are detachably connected.

[0020] More preferably, the locking area is a groove formed on the circumferential inner surface of the lid, and the groove engages with the outer edge of the top of the can.

[0021] More preferably, the slot is an annular groove structure.

[0022] More preferably, several card slots are distributed at the same horizontal height.

[0023] More preferably, the packaging fixing area is a medical rubber fixing sleeve, one end of which is softly connected to the end of the clamping area away from the top surface of the lid, and the internal space shape of the medical rubber fixing sleeve is adapted to the shape of the can body extending downward from the outer edge of the top of the can.

[0024] More preferably, the wrapping fixing area includes a medical rubber fixing piece and a connector. One end of the medical rubber fixing piece is softly connected to the end of the clamping area away from the top surface of the cover. Vertical mounting openings are formed on both sides of the medical rubber fixing piece, and the two sides of the mounting openings are connected by the connector.

[0025] More preferably, the connector is a connecting strip fixedly connected to one edge of the mounting port, and the inner surface of the connecting strip is connected to the other surface of the mounting port by Velcro.

[0026] More preferably, the connector is a connecting strip with an adhesive area on one side, and the medical rubber fixation piece has a fixing area on both sides corresponding to the mounting surface for connecting the adhesive area. The adhesive area and the fixing area are the adhesive surfaces of the Velcro.

[0027] More preferably, the straw is a flexible tube, and a cap is detachably provided at one end of the straw extending from the top of the cover.

[0028] More preferably, the insertion area includes a locking ring, which is formed on the outer peripheral surface of the cover, and the fastening area can be inserted into the locking ring in both directions.

[0029] More preferably, the insertion area includes a first locking external thread and a second locking external thread, the first locking external thread and the second locking external thread are respectively formed on the upper and lower sides of the outer peripheral surface of the cover, and the first locking external thread and the second locking external thread are threadedly connected to the fastening area.

[0030] More preferably, a connecting area is formed on the package fixing area corresponding to the insertion area, the fastening area has a stepped clearance space, and the connecting area is detachably installed between the insertion area and the fastening area.

[0031] More preferably, the connecting area includes two flexible rings, which are respectively formed on both sides of the wrapping and fixing area, and the two flexible rings are respectively attached to the locking ring and the fastening area.

[0032] More preferably, the connecting area includes a first hard thread and a second hard thread, the first hard thread and the second hard thread are respectively formed on both sides of the wrapping and fixing area, the first hard thread is threadedly connected to the fastening area, and the second hard thread is respectively engaged with the first locking external thread and the second locking external thread.

[0033] More preferably, the cover includes a protective cover for covering the straw inside the cover, one end of the protective cover is hinged to the cover, and the other end of the protective cover is snapped onto the cover.

[0034] Compared with the prior art, the straw cap of the present invention for aluminum cans, during the installation of the clamping area, after aligning the open position of the cap with the top of the aluminum can, directly press the cap downwards. The bottom of the clamping groove first passes the outer edge of the top of the aluminum can and then deforms slightly. As the pressure continues to be pressed downwards, it returns to its original shape and places the outer edge of the top of the aluminum can into the clamping groove. The clamping groove can be a ring structure to clamp the entire outer edge of the top of the aluminum can, or multiple grooves can be distributed at the same horizontal height to clamp the outer edge of the top of the aluminum can from multiple clamping positions. This facilitates installation and disassembly. By prioritizing the installation of the clamping area, not only is the cap initially fixed to the top surface of the aluminum can, which is conducive to the fixation of the cap, but it also guides the subsequent wrapping and fixing area to wrap the aluminum can body extending downwards from the top, further facilitating the use of the wrapping and fixing area.

[0035] Because one end of the wrapping fixing area is softly connected to the end of the clamping area away from the top surface of the lid, the wrapping fixing area can be folded through the soft connection position. That is to say, in the initial state before the lid is used, the wrapping fixing area can be folded upward through the soft connection position to wrap the clamping area. After the clamping area is installed, the wrapping fixing area is folded along the soft connection position towards the can body extending downward from the top outer edge, so that the wrapping fixing area further wraps the surface of the can body extending downward from the top outer edge, and achieves further fixation. Because the clamping area position is pre-fixed, it is easier to fold and fix the wrapping fixing area smoothly.

[0036] With the combined action of the locking area and the wrapping and fixing area, the present invention provides a lid with a simple structure, convenient installation and better installation and fixing effect with aluminum cans, so as to meet the user's habit of drinking with a straw.

[0037] In addition, the combination of the insertion area and the connecting area allows the straw holder to be flexibly installed on the straw cap in different styles, further improving the diversity of straw cap and straw holder combinations, making it easier to store, carry and reuse. Users can flexibly choose the combination method according to their needs, better meeting their habit of drinking with straws.

[0038] The present invention also provides a straw holder for an aluminum can, comprising a seat body, wherein the seat body includes a receiving area and a fastening area, the top of the seat body is open to form the receiving area, the receiving area is used to load the bottom of the aluminum can, the fastening area is formed on the inner circumferential surface of the seat body, the fastening area is used to fix the seat body to the insertion area of ​​the lid.

[0039] More preferably, the fastening area includes a buckle formed on the inner circumferential surface of the seat body, and the buckle is inserted into the locking ring of the insertion area.

[0040] More preferably, the engaging area includes a locking internal thread, which is formed on the inner circumferential surface of the seat body, and the locking internal thread is threadedly connected to the first locking external thread and the second locking external thread of the insertion area.

[0041] More preferably, a flexible wrapping pad is detachably installed in the receiving area, and a limiting groove adapted to the bottom of the can is formed inside the flexible wrapping pad. The bottom of the can is snapped into the limiting groove, and an anti-slip pad is fixedly connected to the bottom surface of the base.

[0042] Compared with the prior art, the straw holder of the present invention for aluminum cans, through the cooperation of the receiving area and the fastening area, allows the straw holder to be flexibly combined with the straw cap, meeting different temporary storage needs during use, and can also better store straws for easy carrying and repeated use, providing greater convenience for daily life.

[0043] In summary, this invention not only combines the straw with the cap for convenient drinking, but also achieves "structural interlocking" of the entire straw set in multiple usage states through a detachable interlocking structure between the straw cap and the straw base. This means the straw base serves as a multi-functional reusable base, cap, dust cover, and straw storage chamber, allowing seamless switching between drinking, storage, and transportation states. This structural interlocking not only improves the portability and reusability of the straw set, but also, through the geometric fit of the insertion and locking areas, ensures the overall harmony of the entire straw set under the external forces of daily life.

[0081] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0082] Depend on Figures 1 to 4 The present invention relates to a can straw set, comprising a straw seat and a straw cap that fit together. The straw cap includes a cap body 1, a fixing port 3 for fixing a straw 2 on the top surface of the cap body 1, the straw 2 extending into the can through the fixing port 3, the bottom of the cap body 1 being open, a locking area 4 formed on the circumferential inner surface of the cap body 1, the locking area 4 for detachably connecting the cap body 1 to the neck of the can, a wrapping fixing area 6 formed around the bottom end of the locking area 4 on the cap body 1 for wrapping the can body and folding to cover the straw cap, and an insertion area 10 formed on the outer circumferential surface of the cap body 1 for detachably connecting with the snap-fit ​​area 21 of the straw seat described below.

[0083] The straw holder includes a seat body 19, with an open top forming a receiving area 20 for loading the bottom of an aluminum can. The inner circumferential surface of the seat body 19 opposite to the insertion area 10 forms a locking area 21.

[0084] In these embodiments, the straw holder and the straw cap are relatively fitted together through a detachable connection between the snap-fit ​​area 21 and the insertion area 10. In the initial state, as... Figure 1As shown, the straw cap fits into the straw holder to form a closed, portable set. The straw 2 and the securing area 6 are both stored within this set. In use, the straw holder is separated from the straw cap. First, the straw cap is installed on the neck of the can via the locking area 4. Then, the securing area 6 is fitted to the can body to encircle it. Next, the straw 2 is inserted into the can through the securing opening. Finally, the straw holder is installed at the bottom of the can via its receiving area 20. This separate installation of the straw holder and straw cap significantly improves the overall bonding strength between the set and the can. With its flexible straw holder and straw cap, the straw cap is easier to store and use. It can also be quickly and securely installed on the can. With the further cooperation of the locking area, wrapping and fixing area, insertion area, receiving area and fastening area, the unfolded straw cap and straw holder can be flexibly adjusted to fit according to usage needs. This ensures that users' drinking habits with straws are met, while also allowing the can to be sealed and temporarily stored in a timely manner. In addition, the various combination methods make it easier to store and carry, allowing for repeated use at any time and providing greater flexibility.

[0085] Furthermore, the combination of the straw cap and straw holder not only facilitates drinking by connecting the straw to the cap, but also achieves "structural interlocking" of the entire straw set across multiple usage states through a detachable interlocking structure between the cap and holder. This means the straw holder functions as a base, cap, dust cover, and straw storage chamber, allowing for seamless switching between drinking, storage, and transportation modes. This structural interlocking not only improves the portability and reusability of the straw set, but also ensures overall harmony under the influence of external forces in daily life through the geometric fit of the insertion and locking areas.

[0086] In some embodiments of the can straw kit, a positioning flange 27 is formed on the outer peripheral surface of the straw 2. The positioning flange 27 is detachably snapped into the fixing port 3. The straw 2 has a first position and a second position.

[0087] In the first position, the straw 2 extends downward into the interior of the can via the fixing port 3; in the second position, the straw 2 is fixed to the fixing port 3 by the positioning flange 27 and is located on one side of the lid 1.

[0088] In these embodiments, the positioning flange 27 is integrally formed with the straw 2, which can be understood as a protrusion of a certain thickness on one side of the straw. The first position and the second position are switched by changing the direction of this protrusion. The detachable engagement between the positioning flange 27 on the straw 2 and the fixing port 3 on the cover 1 allows the straw 2 to have an adjustable working position, such as... Figure 3-4As shown, in the first position, the straw 2 extends through the fixed opening 3 and below the liquid surface inside the can. At this time, the positioning flange 27 is inserted into the fixed opening 3, facilitating direct drinking. When storage or transportation is required, the straw 2 can be removed, and the positioning flange 27 can be rotated and locked into the fixed opening 3. At this time, the positioning flange 27 is rotated 90 degrees and inserted into the fixed opening 3, so that the straw 2 is located on one side of the lid 1, either on the upper or lower side of the lid 1. The operation of taking out and storing the straw is convenient, making it easier to carry and recycle, effectively meeting the user's need to flexibly adjust the position of the straw. Optionally, the positioning flange 27 can be a cube, with the straw 2 passing through the cube at an off-center position. Due to the properties of the cube, when the straw 2 is inserted into the can (the straw 2 is in a vertical state), the positioning flange 27 can be inserted into the fixed opening 3. When the straw 2 is laid flat (i.e., in a horizontal state), the positioning flange 27 can also be inserted into the fixed opening 3 (on the side away from the straw 2). To further improve sealing, an elastic sealing lip can be provided on the inner wall of the fixing port 3. When the positioning flange 27 passes through or engages, the sealing lip forms an interference fit with the positioning flange 27 or the outer wall of the straw 2 to improve sealing and prevent liquid or dust leakage. The straw 2 can also preferably be made of food-grade silicone or thermoplastic elastomer (TPE) material, which has sufficient elastic recovery force to ensure dimensional stability after repeated insertion and removal.

[0089] Depend on Figures 5 to 30 Provided, some embodiments of the present invention relate to a straw cap for an aluminum can, comprising a cap body 1, the cap body 1 being open at the bottom and having a fixing opening 3 on its top surface for fixing a straw 2, the straw 2 extending into the interior of the aluminum can through the fixing opening 3, the cap body 1 comprising:

[0090] The locking area 4 is formed on the inner circumferential surface of the cover 1, and its shape is adapted to the shape of the outer edge 5 of the top of the can and can be detachably connected to the outer edge 5 of the top of the can.

[0091] The wrapping and fixing area 6 is softly connected at one end to the clamping area 4 away from the top surface of the lid 1. The wrapping and fixing area 6 is used to extend and wrap the outer wall surface of the can extending downward from the top outer edge 5 of the can.

[0092] The insertion area 10 is formed on the outer peripheral surface of the cover 1, and the insertion area 10 is detachably connected to the fastening area 21 of the seat 19.

[0093] In the straw cap for aluminum cans of the present invention, the cap body 1 is installed by aligning its open bottom position with the top opening of the aluminum can. A fixing port 3 for fixing the straw 2 is provided on the top of the cap body 1. The straw 2 extends into the interior of the aluminum can through the fixing port 3 and is fixedly connected to the fixing port 3. This makes it convenient to drink the beverage inside the aluminum can through the straw 2 after the cap body 1 is installed on the aluminum can. The specific method of fixing the straw 2 to the cap body 1 can also be any of the prior art. The present invention does not limit it too much.

[0094] With the cooperation of the insertion area 10 and the fastening area 21, the loading and unloading of the cover 1 is convenient and easy to use at any time. It not only ensures the stability of the assembly, but also improves portability and is more suitable for repeated use.

[0095] To achieve a more secure and convenient installation of the lid 1 with the straw 2 fixed on the can, the present invention is adopted, wherein a locking area 4 is formed on the circumferential inner surface of the lid 1. Since the shape of the locking area 4 is adapted to the shape of the outer edge 5 of the top of the can and can be detachably connected to the position of the outer edge 5 of the top of the can, the specific structure of the locking area 4 is a groove formed on the circumferential inner surface of the lid 1. When the locking area 4 is installed on the outer edge 5 of the top of the can, the outer edge of the top of the can is placed in the groove and locked and fixed on the outer edge 5 of the top of the can.

[0096] During the installation of the clamping area 4, after aligning the open position of the lid 1 with the top of the can, press the lid 1 directly downwards. The bottom of the clamping groove first passes the outer edge 5 of the top of the can and then deforms slightly. As you continue to press downwards, it returns to its original shape and places the outer edge of the top of the can into the clamping groove. The clamping groove can be a ring structure to clamp the entire outer edge of the top of the can, or multiple grooves can be distributed at the same horizontal height to clamp the outer edge of the top of the can from multiple clamping positions. This facilitates installation and disassembly. By prioritizing the installation of the clamping area 4, not only is the lid 1 initially fixed on the top surface of the can, which is conducive to the fixation of the lid 1, but it also serves as a guide for the subsequent wrapping and fixing area 6 to wrap the can body extending downwards from the top, further facilitating the use of the wrapping and fixing area 6.

[0097] With the combined action of the locking area 4 and the wrapping and fixing area 6, the present invention provides a lid with a simple structure, convenient installation and better installation and fixing effect with the can, so as to meet the user's habit of drinking with a straw 2.

[0098] Since one end of the wrapping fixing area 6 is softly connected to the end of the clamping area 4 away from the top surface of the cover 1, the wrapping fixing area 6 can be folded through the soft connection position. That is to say, in the initial state before the cover 1 is used, the wrapping fixing area 6 can be folded upward through the soft connection position to wrap the clamping area 4. After the clamping area 4 is installed, the wrapping fixing area 6 is folded along the soft connection position towards the can body extending downward from the top outer edge of the can. Finally, the wrapping fixing area 6 further wraps the surface of the can body extending downward from the top outer edge of the can, achieving further fixation. Since the clamping area 4 is pre-fixed, it is easier to fold and fix the wrapping fixing area 6 smoothly.

[0099] The specific structure of the fixed area 6 can be structure one:

[0100] The wrapping and fixing area 6 is a medical rubber fixing sleeve. One end of the medical rubber fixing sleeve is softly connected to the end of the clamping area 4 away from the top surface of the lid 1. The internal space shape of the medical rubber fixing sleeve is adapted to the shape of the can body extending downward from the outer edge 5 of the top of the can, which facilitates the installation of the medical rubber fixing sleeve and provides a better wrapping and fixing effect on the outer wall surface of the can extending downward from the outer edge 5 of the top of the can. The bottom edge of the wrapping and fixing area 6 can be located at any height on the outer wall surface of the can, preferably at the position where the can is normally held. In this way, when the beverage inside the can is chilled, the position of the medical rubber fixing sleeve held by hand can further play a role in heat preservation and cold insulation.

[0101] Structure 2 of the fixed area 6:

[0102] The wrapping and fixing area 6 includes a medical rubber fixing piece 7 and a connector 8. One end of the medical rubber fixing piece 7 is flexibly connected to the end of the clamping area 4 away from the top surface of the lid 1. Vertical mounting openings 9 are formed on both sides of the medical rubber fixing piece 7. The two sides of the mounting openings 9 are connected by the connector 8. During the installation of the wrapping and fixing area 6, the medical rubber fixing piece 7 is folded downward at the position where it is flexibly connected to the clamping area 4 to cover and wrap the outer wall surface of the can extending downward from the outer edge 5 of the top of the can. The tightness of the can's outer wall surface is adjusted by the size of the opening of the mounting opening 9. Finally, the two sides of the mounting opening 9 are connected by the connector 8. The side connection closure not only facilitates the installation of the medical rubber fixation piece 7, but also allows the installation port 9 to be opened through the connector 8 during disassembly, further facilitating the removal of the wrapping fixation area 6 and the clamping area 4. This ultimately enables the reuse of the lid 1 and provides better wrapping and fixation of the outer wall surface of the can extending downwards from the top outer edge 5. The bottom edge of the medical rubber fixation piece 7 can be located at any height on the outer wall surface of the can, preferably at a position that covers the normal handheld position of the can. This allows the medical rubber fixation piece 7 to further insulate against heat when the beverage inside the can is chilled.

[0103] Please refer to the following: Figure 6 as well as Figure 7 As shown, specifically, the locking area 4 is a groove formed on the inner circumferential surface of the lid 1. The groove engages with the outer edge 5 of the top of the can. During the installation of the locking area 4, after aligning the open position of the lid 1 with the top of the can, the lid 1 is pressed down directly. The bottom of the groove first passes the outer edge 5 of the top of the can and then deforms slightly. As the pressure continues to be applied downwards, the lid returns to its original shape, and the outer edge of the top of the can is placed in the groove. By prioritizing the installation of the locking area 4, the lid 1 is not only initially fixed to the top surface of the can, which is beneficial for fixing the lid 1, but also serves as a guide for the subsequent wrapping and fixing area 6 to wrap the can body extending downwards from the top, further facilitating the wrapping and fixing area 6 to play its fixing role.

[0104] Please refer to the following: Figure 6 As shown, specifically, the slot is an annular groove structure that clamps the outer edge of the circular top of the entire can, resulting in a better clamping effect.

[0105] Please refer to the following: Figure 6 As shown, specifically, several slots are distributed at the same horizontal height to clamp the outer edge of the top of the can from multiple clamping positions, further facilitating installation and disassembly.

[0106] Please refer to the following: Figures 5 to 8As shown, specifically, the wrapping and fixing area 6 is a medical rubber fixing sleeve. One end of the medical rubber fixing sleeve is softly connected to the end of the clamping area 4 away from the top surface of the lid 1. The internal space shape of the medical rubber fixing sleeve is adapted to the shape of the can body extending downward from the outer edge 5 of the top of the can, which facilitates the installation of the medical rubber fixing sleeve and provides a better wrapping and fixing effect on the outer wall surface of the can extending downward from the outer edge 5 of the top of the can. The bottom edge of the wrapping and fixing area 6 can be located at any height on the outer wall surface of the can, preferably at the position where the can is normally held. In this way, when the beverage inside the can is chilled, the position of the medical rubber fixing sleeve held by hand can further play a role in heat preservation and cooling.

[0107] Please refer to the following: Figure 9 as well as Figure 10 As shown, specifically, the wrapping and fixing area 6 includes a medical rubber fixing piece 7 and a connector 8. One end of the medical rubber fixing piece 7 is flexibly connected to the end of the clamping area 4 away from the top surface of the lid 1. Vertical mounting openings 9 are formed on both sides of the medical rubber fixing piece 7. The two sides of the mounting openings 9 are connected by the connector 8. During the installation of the wrapping and fixing area 6, the medical rubber fixing piece 7 is folded downward at the position where it is flexibly connected to the clamping area 4 to cover and wrap the outer wall surface of the can extending downward from the outer edge 5 of the top of the can. The tightness of the can's outer wall surface is adjusted by the size of the mounting opening 9. Finally, the installation is secured by the connector 8. The connection closure on both sides of the opening 9 not only facilitates the installation of the medical rubber fixation piece 7, but also allows the installation opening 9 to be opened through the connector 8 during disassembly, further facilitating the removal of the wrapping fixation area 6 and the clamping area 4. This ultimately enables the reuse of the lid 1 and provides better wrapping and fixation of the outer wall surface of the can extending downwards from the top outer edge 5 of the can. The bottom edge of the medical rubber fixation piece 7 can be located at any height on the outer wall surface of the can, preferably at a position that covers the normal hand position of the can. This way, when the beverage inside the can is chilled, the hand position of the medical rubber fixation piece 7 further provides insulation and cold protection.

[0108] Please refer to the following: Figure 9 As shown, specifically, the connector 8 is a connecting strip fixedly connected to one side edge of the mounting port 9. The inner surface of the connecting strip is connected to the other side surface of the mounting port 9 by Velcro. The mounting port 9 can be opened and closed by the Velcro position, which further facilitates the installation and removal of the wrapping fixing area 6 and provides a better sealing effect for the mounting port 9.

[0109] Please refer to the following: Figure 10 as well as Figure 11As shown, specifically, the connector 8 is a connecting strip with an adhesive area on one side, and the medical rubber fixing piece 7 has fixing areas on both sides corresponding to the mounting opening 9 for connecting the adhesive area. The adhesive area and the fixing area are the adhesive surfaces of the Velcro. During use, after the clamping area 4 is installed on the outer edge 5 of the top of the can, the medical rubber fixing piece 7 can be folded upward along the soft connection position between it and the clamping area 4 after removing the connecting strip, and then the lid 1 position corresponding to the clamping area 4 can be wrapped, and the straw 2 position exposed on the top of the lid 1 can be wrapped. Then the connecting strip is used as a binding strap to fix the wrapped shape of the medical rubber fixing piece 7, preventing the exposed straw 2 position from getting dusty.

[0110] Please refer to the following: Figures 5 to 11 As shown, specifically, the straw 2 is a flexible tube, which is easy to store inside the outer packaging box.

[0111] Furthermore, the straw 2 is detachably fitted with a cap at one end extending from the top of the cover 1 to prevent dust during use.

[0112] In some embodiments of straw caps for aluminum cans, the insertion area 10 includes a locking ring 11 formed on the outer peripheral surface of the cap body 1, and the fastening area 21 can be inserted into the locking ring 11 in both directions.

[0113] In these implementations, such as Figure 12-13 As shown, the locking ring 11 is a circular ring surrounding the outer circumference of the cover 1. The locking ring 11 allows for quick installation and separation of the straw cap and straw holder. Its bidirectional insertion feature allows the straw holder to function as both a bottom support and a top cover when the straw cap is inverted or stored, greatly improving the assembly flexibility of the kit. Furthermore, the locking ring 11 can also be one or more annular protrusions surrounding the outer circumference of the cover 1. Correspondingly, the snap-fit ​​area 21 on the straw holder has a corresponding annular groove or elastic latch (not shown in the figure). During installation, axial force is applied to cause the groove or latch of the snap-fit ​​area 21 to pass over the protrusion of the locking ring 11 and engage with it, achieving convenient bidirectional insertion. That is, the straw holder can be connected to the locking ring 11 from either the top or bottom of the cover 1.

[0114] In some embodiments of straw caps for aluminum cans, the insertion area 10 includes a first locking external thread 12 and a second locking external thread 13. The first locking external thread 12 and the second locking external thread 13 are respectively formed on the upper and lower sides of the outer peripheral surface of the cap body 1. The first locking external thread 12 and the second locking external thread 13 are threadedly connected to the fastening area 21.

[0115] In these implementations, such as Figure 14-15As shown, a second locking external thread 13 and a first locking external thread 12 are respectively provided on the upper and lower sides of the outer circumference of the cover 1, forming two independent threaded connection interfaces. Correspondingly, the snap-fit ​​area 21 on the straw holder is provided with a matching locking internal thread 23. The user can choose to screw the straw holder onto the upper second locking external thread 13 or the lower first locking external thread 12 through its internal thread. Compared with the aforementioned direct plug-in connection method, the threaded connection provides higher connection strength and sealing performance, making it more suitable for carrying. Through the two threaded interfaces, the straw holder can be installed above or below the cover 1, making it easier to store and carry. It can also be installed on the upper part of the cover 1 for temporary storage of straws, realizing multiple uses for one cover.

[0116] It should be understood that the specific structure of the plug-in area 10 can be flexibly selected according to the usage requirements. This article only provides examples and does not impose any specific limitations. Similarly, the installation method of the plug-in area 10 and the latching area 21 can also be a common snap-fit ​​or locking structure, which will not be elaborated on in this article.

[0117] In a further implementation, such as Figure 16 As shown, when the wrapping fixing area 6 is folded over to wrap the cover 1, the wrapping fixing area 6 is located between the insertion area 10 and the fastening area 21, which can provide a stable connection to a certain extent. For example, it can be connected by the locking ring 11 and can be used for temporary installation. However, the long-term connection effect will be affected by the material, etc. Therefore, the stability of the connection is improved by adding a connecting area 14, as described in the following implementation method.

[0118] In some embodiments of straw caps for aluminum cans, a connecting area 14 is formed on the wrapping and fixing area 6 corresponding to the insertion area 10, and the fastening area 21 has a stepped clearance space. The connecting area 14 is detachably installed between the insertion area 10 and the fastening area 21.

[0119] In these implementations, such as Figure 17 As shown, the connecting area 14 serves as an intermediate connector between the insertion area 10 and the fastening area 21, and is positioned on the wrapping and fixing area 6, corresponding to the position of the insertion area 10. Since the wrapping and fixing area 6 itself has a certain thickness and flexibility, direct threaded or snap-fit ​​connections on its exterior may lead to unstable fits. The connecting area 14 provides a rigid or semi-rigid connecting platform, which is detachably installed between the insertion area 10 and the fastening area 21 of the straw holder, ensuring a secure connection after the wrapping and fixing area 6 is folded. This improves the stability of the connection between the straw holder and the straw cap, enhances the overall structural stability after assembly, and allows users to flexibly adjust the assembly method. Since the fastening area 21 needs to connect both the straw cap when the wrapping and fixing area 6 is not folded and the straw cap after it is folded, the stepped clearance space on the fastening area 21 simultaneously meets both installation requirements, thus ensuring installation stability.

[0120] In some embodiments of straw caps for aluminum cans, the connecting area 14 includes two flexible rings 15, which are formed on both sides of the wrapping and fixing area 6, and are respectively attached to the locking ring 11 and the fastening area 21.

[0121] In these implementations, such as Figure 18-19 As shown, the connecting area 14 is specifically composed of two independent flexible rings 15, which are respectively formed or attached to the inner and outer sides of the wrapping and fixing area 6. When the wrapping and fixing area 6 is folded over to wrap the cover 1, one flexible ring 15 is attached to the locking ring 11 of the cover 1, and the other flexible ring is attached to the corresponding position of the straw seat fastening area 21, cooperating with the fastening area 21 (i.e., the fastening ring 22) to complete the connection. By utilizing the elastic deformation of the two flexible rings 15 to generate a pre-tightening force, the tightness of the connection is significantly improved, while ensuring a stable connection between the straw cover and the straw seat. It is important to understand that when the flexible ring 15 is present, the fastening area 21 needs to be connected to the locking ring while also connecting to the outer flexible ring 15. Since there is a thickness difference between the two, the corresponding fastening area 21 has a stepped clearance space. That is to say, part of the fastening area 21 is used to connect to the locking ring 11, and another part is used to connect to the outer flexible ring 15. This allows the straw holder to be installed below the straw cap whether the wrapping fixing area 6 is folded or not, and similarly, the straw holder can also be installed above the straw cap.

[0122] In some embodiments of straw caps for aluminum cans, the connecting area 14 includes a first hard thread 16 and a second hard thread 17, which are respectively formed on both sides of the wrapping and fixing area 6. The first hard thread 16 is threadedly connected to the fastening area 21, and the second hard thread 17 is engaged with the first locking external thread 12 and the second locking external thread 13.

[0123] In these implementations, such as Figure 20-21As shown, the connecting area 14 is composed of a first hard thread 16 and a second hard thread 17. The first hard thread 16 includes an upper thread and a lower thread with opposite helical directions, and its central region is a plane, so that both the upper and lower sections of the first hard thread 16 can be threadedly connected to the engaging area 21 (i.e., the locking internal thread 23). Similarly, the second hard thread 17 consists of two threads with different helical directions, so that the second hard thread 17 can be engaged with the first locking external thread 12 and the second locking external thread 13, thereby fixing the entire connecting area 14 to the cover 1. The cooperation of the first hard thread 16 and the second hard thread 17 actually provides a thread specification conversion or extension interface, which allows the wrapping fixing area 6 to be folded and stably fitted to the cover 1 while ensuring the stable installation of the straw holder, increasing the versatility of the connection position, and making it easy to adjust the installation method of the straw holder according to the usage scenario. The fastening area 21 is connected to the aforementioned flexible ring 15 in the same way. In order to stably connect the first locking external thread 12, the second locking external thread 13, and the first hard thread 16, a stepped clearance space is formed at the corresponding position of the fastening area 21 to ensure flexible conversion of the straw seat installation method.

[0124] The way the straw cap is attached to the can can be flexibly chosen, such as... Figure 22-25 As shown, where, as Figure 22-23 As shown, the straw cap is installed on the neck of the can, wrapping around the can body with the fixing area 6. The corresponding straw holder is installed on the bottom of the can for easy drinking. Furthermore, the cap 1 has air holes 28 to balance the air pressure inside and outside the cap 1, ensuring smooth drinking. Figure 24 As shown, the straw holder is installed on the straw cap from above, which can seal the straw for temporary storage, and the wrapping and fixing area 6 also makes it easier to carry the can. Figure 25 As shown, when temporarily storing sealed aluminum cans, the wrapping and securing area 6 can be folded over to wrap the straw cap and straw 2, thus completing the sealed storage. Furthermore, after folding over the wrapping and securing area 6, the straw holder can be installed on the straw cap. For longer storage times, both the wrapping and securing area 6 and the straw 2 can be sealed together, further improving storage safety. It is evident that the installation method of the straw cap and straw holder can be flexibly selected according to usage requirements; this article only provides examples and does not impose specific limitations.

[0125] In some embodiments of straw caps for aluminum cans, the cap 1 includes a protective cover 18 for covering the straw 2 inside the cap 1. One end of the protective cover 18 is hinged to the cap 1, and the other end of the protective cover 18 is snapped onto the cap 1.

[0126] In these embodiments, to improve convenience, a protective cover 18 is also provided on the cover 1. Figure 26-30As shown, one end of the straw 2 is connected to the cover 1 via a hinge, such as a flexible sheet or a pivot, and the other end is equipped with a buckle. When not in use or during transport, the straw 2 can be bent, and the protective cover 18 can be rotated to cover the top of the cover 1, and locked in place by the buckle, thus completely enclosing the straw 2 within the cavity formed by the protective cover 18 and the top surface of the cover 1. Figures 28-30 As shown, the protective cover 18 effectively protects the straw 2 from damage when not in use and prevents accidental damage due to collisions during transport. The protective cover 18 can be an arc-shaped top cover with a circumferential raised edge 31 on the edge of the cover 1. One end of the top cover is hinged to the raised edge 31, and the other end is locked onto the raised edge 31 via a buckle. When the top cover is closed, the pressure plate 30 presses down on the straw 2, bending it, while the plug 29 seals the air hole 28 on the cover 1. When the top cover is opened, the straw 2 springs out automatically, facilitating one-handed opening and closing and improving the user experience.

[0127] It's important to understand that although a protective cover has been added to the straw cap, the straw cap and straw holder can still be installed using the aforementioned installation method, such as... Figure 28 As shown, of course, some installation methods can be omitted when necessary to ensure proper fit between the straw cap and the straw holder. Therefore, the installation methods of the straw cap and the straw holder will not be described in detail in this embodiment.

[0128] Depend on Figures 31 to 35 According to some embodiments of the present invention, a straw holder for an aluminum can is provided, comprising a seat 19, wherein the seat 19 includes a receiving area 20 and a fastening area 21, the top of the seat 19 is open to form the receiving area 20 for loading the bottom of the aluminum can, and the fastening area 21 is formed on the inner circumferential surface of the seat 19 for fixing the seat 19 onto the insertion area 10 of the lid 1.

[0129] In these implementations, such as Figure 31As shown, the top of the straw holder 19 is recessed inward to form an open receiving area 20 for supporting the bottom of the can. A fastening area 21 is provided on its inner circumference surface, the structure of which matches the insertion area 10 on the straw cap, for example, the buckle 22 matches the locking ring 11. In use, the bottom of the can is placed into the receiving area 20. The straw holder and straw cap work together to ensure portability and provide an independent base for the can, increasing its stability. Furthermore, to accommodate cans of different heights and improve the stability of the seat 19, the sidewall of the seat 19 can be a retractable corrugated tube structure (not shown in the figure), allowing the depth of the receiving area 20 to be adjusted by stretching or compressing, thus better supporting the can. Through the cooperation of the receiving area 20 and the fastening area 21, the straw holder can be flexibly combined with the straw cap, meeting different temporary storage needs during use, and also better storing straws for easy carrying and reuse, providing greater convenience for daily life.

[0130] In some embodiments of straw holders for aluminum cans, the fastening area 21 includes a buckle 22 formed on the inner circumferential surface of the seat body 19, and the buckle 22 is inserted into the locking ring 11 of the insertion area 10.

[0131] In these implementations, such as Figure 32 As shown, the fastening area 21 is a buckle 22 structure, which cooperates with the locking ring 11 of the insertion area 10 on the straw cap to achieve a plug-in installation connection. This structure is simple, has low manufacturing cost, and is quick to operate, making it suitable for scenarios requiring frequent disassembly and assembly. Furthermore, the buckle 22 is one or more annular protrusions on the inner circumference of the base 19 that match the aforementioned locking ring 11. During installation, the cap 1 is aligned with the opening of the base 19 and pressed down to complete the installation. It should be understood that, similar to the installation principle of the insertion area 10, when the buckle 22 is adapted to fold over the wrapping fixing area 6, the buckle 22 is stepped (see [reference]). Figure 18-19 As shown, with Figure 32 The stepped structure of the above embodiments is the same, allowing for more flexible installation.

[0132] In some embodiments of straw holders for aluminum cans, the fastening area 21 includes a locking internal thread 23, which is formed on the inner circumferential surface of the seat body 19. The locking internal thread 23 is threadedly connected to the first locking external thread 12 and the second locking external thread 13 of the insertion area 10.

[0133] In these implementations, such as Figure 33As shown, the engaging area 21 employs a locking internal thread 23, which is formed on the inner circumferential surface of the seat 19. By rotating the seat 19, it engages with either the first locking external thread 12 or the second locking external thread 13 on the cover 1, achieving a threaded fastening connection. Compared to the aforementioned plug-in connection method, the threaded connection provides greater locking force and a better sealing effect, resulting in a more stable and reliable connection. Similarly, when the locking internal thread 23 is adapted to fold over the wrapping fixing area 6, the locking internal thread 23 is stepped (see [reference needed]). Figure 20-21 As shown, with Figure 33 The stepped structure of the above embodiments is the same, allowing for more flexible installation.

[0134] It should be understood that the connection structure of the snap-fit ​​area 21 in the embodiment is only an example and is adapted to the insertion area 10 in the aforementioned embodiment of the straw cap for a can, and is not specifically limited in this document.

[0135] In some embodiments of straw holders for aluminum cans, a flexible wrapping pad 24 is detachably installed in the receiving area 20. The flexible wrapping pad 24 has a limiting groove 25 that is adapted to the bottom of the can. The bottom of the can and the limiting groove 25 are snapped together. An anti-slip pad 26 is fixedly connected to the bottom surface of the seat body 19.

[0136] In these implementations, such as Figures 34-35 As shown, to further enhance the fixation and adaptability of the can bottom, a flexible wrapping pad 24 is detachably installed within the receiving area 20. The flexible wrapping pad 24 can be made of silicone, rubber, or elastic foam, and has a limiting groove 25 in its center. The shape and size of the limiting groove 25 match the flange profile of the bottom of a standard aluminum can. During installation, the bottom of the can is pressed into the limiting groove 25, and the elastic deformation of the flexible material tightly holds the bottom of the can in place. Simultaneously, an anti-slip pad 26 is fixed to the bottom surface of the base 19. The locking mechanism of the limiting groove 25 not only protects the bottom of the can from impacts but also firmly secures aluminum cans with different bottom details, preventing them from wobbling within the receiving area 20. The anti-slip pad 26 increases the friction between the straw holder and supporting surfaces such as the table, improving overall stability and safety.

[0137] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. The above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
