Background Technology

[0002] Card holders are common card storage tools used in daily life and work, mainly for protecting work permits, badges, ID cards, bank cards, membership cards, etc., preventing them from being worn, bent, lost, dusted, or waterproofed. Most existing card holders are single-layered, with cards directly inserted or placed inside. While simple in structure, this design suffers from insufficient protection and poor convenience in removing and storing cards.

[0003] Meanwhile, existing card sleeve structures suffer from drawbacks such as difficulty in removing cards after insertion, and the connection between the lanyard and the sleeve is not secure enough, leading to breakage over time. These issues fail to meet users' demands for protection, convenience, and stability. Therefore, a well-designed, protective, portable, and stable double-layer card sleeve structure is urgently needed to address these problems. Summary of the Invention

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings: like Figures 1-33 As shown, the present invention provides a double-layer card sleeve, the core design concept of which is: The double-layer card sleeve includes an inner card sleeve 10 and an outer card sleeve 20. The inner card sleeve 10 has a card slot 11 along a first direction for inserting a card into the inner card sleeve 10. The outer card sleeve 20 has a slot 21 along a second direction for inserting the inner card sleeve into the outer card sleeve. The inner card sleeve 10 can only be inserted into the slot 21 from one end and cannot be disengaged from the slot 21 from the other end. The first direction and the second direction are not the same direction. Preferably, the angle between the first direction and the second direction is 60° to 120°. More preferably, the first direction and the second direction are perpendicular.

[0022] Based on the above configuration, the card can be inserted into the inner sleeve along the first direction to achieve initial protection, and the inner sleeve can be inserted into the outer sleeve along the second direction, which is different from the first direction, to achieve secondary protection. The cooperation between the inner and outer sleeves makes the four sides and two sides of the card seamless solid or partially hollowed-out solid. The double-layer protective structure can effectively isolate external dust and water stains, while resisting external impacts and squeezing, avoiding card wear and bending, and significantly improving the protective performance. At the same time, it is easy to remove.

[0023] Based on the above core design concept, this application can also be modified as follows: 1. One end (top) of the outer card sleeve 20 is provided with a first notch 22 that communicates with the slot 21. The opening size (width) of the first notch 22 is smaller than the opening size (width) of the slot 21 and the width of the inner card sleeve. The width of the inner card sleeve 10 is the width of the inner card sleeve 10 in the direction of insertion into the outer card sleeve 20. A limiting platform 23 is formed at the connection between the first notch 22 and the slot 21. Based on the setting of the limiting platform 23, the inner card sleeve can only be inserted into the slot from one end of the slot and cannot be disengaged from the slot 21 from the other end of the slot 21.

[0024] Furthermore, when the design form 1 above is selected, the structure of the inner sleeve of the present invention is as follows: When the inner card sleeve 10 is inserted into the outer card sleeve 20 and the top of the inner card sleeve 10 abuts against the limiting platform 23, a portion of the top area of ​​the inner card sleeve 10 protrudes from the first notch 22 to form a push platform 112 that facilitates pushing the inner card sleeve 10 out of the outer card sleeve 20; wherein, the top of the push platform 112 is higher than the top of the inner card sleeve 10, or, the top of the push platform 112 is flush with the top of the inner card sleeve 10, or, the top of the push platform 112 is lower than the top of the inner card sleeve 10, or, the push platform 112 is lower than the top of the inner card sleeve 10. The top of the push platform 112 is flush with the top of the outer card sleeve 20, or the top of the push platform 112 is higher than the top of the outer card sleeve 20; the top areas of the inner card sleeves on both sides of the push platform 112 serve as the shoulders 113 of the inner card sleeve 10, and the shoulders 113 of the inner card sleeve 10 are used to abut against the limiting platform 23; it should be noted that when the inner card sleeve is inserted into the outer card sleeve and the shoulders of the inner card sleeve abut against the limiting platform, the platform of the push platform is formed relative to the first notch, that is, the top of the push platform is higher than the bottom of the first notch.

[0025] Based on the above structure, the inner sleeve of the present invention can also be modified as follows: (A-1) The inner sleeve 10 has a first hanging hole 12 on its push platform 112. When the inner sleeve 10 is inserted into the outer sleeve 20 and the shoulder of the inner sleeve 10 abuts against the limiting platform, the first hanging hole 12 of the inner sleeve 10 is fully or partially exposed from the first notch 22. A hanging device can be selectively connected to the exposed first hanging hole 12. The hanging device includes one of a hanging rope and a hook. Under the limiting action of the hanging device and / or based on the friction between the inner sleeve and the outer sleeve, the inner sleeve will not fall downward from the outer sleeve. (A-2) The inner card sleeve 10 does not have a first hanging hole 12 on its push platform 112. When the inner card sleeve 10 is inserted into the outer card sleeve 20 and the top of the inner card sleeve 10 is against the limiting platform, the push platform of the inner card sleeve 10 extends out from the first notch 22. Based on the friction between the inner card sleeve and the outer card sleeve, the inner card sleeve will not fall out of the outer card sleeve.

[0026] The design options A-1 and A-2 mentioned above can be chosen.

[0027] Furthermore, the inner and outer card sleeves can also be made in one or more of the following variations: B. The bottom of the inner sleeve 10 is provided with a second hanging hole 14.

[0030] It should be noted that at least one of the separately designed inner card sleeves (1) to (7) and at least one of the separately designed outer card sleeves (1) to (4), and the inner card sleeve and outer card sleeves designed together (1) and (A) to (C) can be combined in any form to form various deformed double-layer card sleeves, provided that the core concept is not contradictory. The following embodiments only list some of the double-layer card sleeve structures for illustration. Example 1:

[0031] like Figures 1-5As shown, the present invention provides a double-layer card sleeve, including: an inner card sleeve 10 and an outer card sleeve 20; the inner card sleeve 10 has a card slot 11 along the left and right direction for inserting a card into the inner card sleeve 10; the outer card sleeve 20 has a slot 21 along the up and down direction for inserting the inner card sleeve 10 into the outer card sleeve 20, and the size of the inner card sleeve 10 matches the slot 21.

[0032] Specifically: The outer card sleeve 20 of the present invention has an insertion port at the bottom that matches the size of the inner card sleeve 10, and the top of the outer card sleeve 20 has a first notch 22 that communicates with the slot 21. The size of the first notch 22 is smaller than the size of the insertion port. The card slot 11 of the inner card sleeve 10 extends through the inner card sleeve 10 from left to right. The top of the inner card sleeve 10 has a first hanging hole 12, which consists of a main hanging hole and two auxiliary hanging holes. The inner card sleeve 10 is inserted into the outer card sleeve 20 through the bottom insertion port of the outer card sleeve 20. When the inner card sleeve 10 is inserted upward until the top of the outer card sleeve 20 abuts against the limiting platform 23 of the slot 21, the first hanging hole 12 of the inner card sleeve 10 is exposed from the first notch 22 of the outer card sleeve 20, and the card slot 11 is not exposed from the bottom of the outer card sleeve 20. That is, the bottom of the inner card sleeve 10 can be flush with the bottom of the outer card sleeve 20, slightly exposed, or slightly smaller than the bottom of the outer card sleeve 20. The card sleeve can be assembled by installing a hanging rope at the first hanging hole 12 and can be put around the user's neck. At the same time, a hook can be used to replace the hanging rope.

[0033] In use, first insert the card into the inner card sleeve 10 along the left and right card slots 11, and then insert the inner card sleeve 10 with the card inserted into the outer card sleeve 20 from the bottom. The first hanging hole 12 at the top of the inner card sleeve 10 is exposed from the first notch 22 of the outer card sleeve 20. Then, a hanging rope or hook can be installed on the exposed first hanging hole 12. Under the limiting action of the hanging rope or hook and / or based on the friction between the inner card sleeve and the outer card sleeve, the inner card sleeve 10 will not fall out of the outer card sleeve 20, so as to realize the assembly and use of the card sleeve. Furthermore, the inner card sleeve 10 and the outer card sleeve 20 can be made of conventional card sleeve materials such as metal or plastic. The light transmittance of the inner card sleeve 10 and the outer card sleeve 20 can be fully transparent, opaque, or partially transparent using a combination of multiple materials. For example, both the inner card sleeve 10 and the outer card sleeve 20 can be made of transparent plastic to hold cards that need to display card information, such as conference admission badges. Alternatively, both the inner card sleeve 10 and the outer card sleeve 20 can be made of opaque metal to hold cards that do not display card information, such as ID cards. Alternatively, one side of the inner card sleeve can be transparent and the other side can be opaque, and / or one side of the outer card sleeve can be transparent and the other side can be opaque. Alternatively, the outer card sleeve 20 and / or the inner card sleeve 10 can combine a metal frame with a plastic window to display card information in a specific location through the window. Example 2:

[0034] like Figure 6As shown, the difference from Embodiment 1 is that: in Embodiment 1, the card slot 11 of the inner card sleeve 10 is through on both sides, and the first hanging hole 12 consists of one main hanging hole and two auxiliary hanging holes; in Embodiment 2, the card slot 11 of the inner card sleeve 10 is a non-through structure with one side slotted and the other side closed, and the first hanging hole 12 has only one main hanging hole; so as to meet different application occasions. Example 3:

[0035] like Figures 7-9 As shown, the difference from Embodiment 1 is that Embodiment 1 is a double card sleeve structure for vertically placing cards, while Embodiment 3 is a double card sleeve structure for horizontally placing cards; at the same time, the first hanging hole 12 of Embodiment 1 consists of one main hanging hole and two auxiliary hanging holes; the first hanging hole 12 of Embodiment 3 has only one main hanging hole; so as to meet different application occasions. Example 4:

[0036] like Figure 10 As shown, the difference from Embodiment 1 is that Embodiment 4 selects to open a first window 13 on one side of the inner card sleeve 10 to expose specific information on the card; at the same time, a sealing film can also be provided on the first window 13; for example, the inner card sleeve 10 is a metal card sleeve, and the first window 13 of the inner card sleeve 10 is provided with a plastic sealing film; to meet different application occasions. Example 5:

[0037] like Figure 11 As shown, the difference from Embodiment 4 is that Embodiment 5 selects to open the first viewing window 13 on both sides of the inner card sleeve 10 to meet different application occasions. Example 6:

[0038] like Figures 12-14 As shown, the difference from Embodiment 1 is that Embodiment 6 further selects to provide a second hanging hole 14 at the bottom of the inner card sleeve 10 and a second notch 24 at the bottom of the outer card sleeve 20; when the inner card sleeve 10 is pushed into place inside the outer card sleeve 20, the first hanging hole 12 at the top of the inner card sleeve 10 is exposed from the first notch 22 of the outer card sleeve 20, and the second hanging hole 14 at the bottom of the inner card sleeve 10 is exposed at the second notch 24; the user can choose to hang related objects at the second hanging hole 14. Example 7:

[0039] like Figure 15 As shown, the difference from Embodiment 1 is that Embodiment 7 further provides a third notch 15 at the entrance end of the card slot 11 of the inner card sleeve 10; when the card is inserted into the inner card slot 11, part of the card is exposed at the third notch 15, which facilitates the insertion and removal of the card. Example 8:

[0040] like Figure 16As shown, the difference from Embodiment 1 is that Embodiment 8 further provides a third notch 15 at the entrance and exit ends of the card slot 11 of the inner card sleeve 10; when the card is inserted into the inner card slot 11, part of the card is exposed at the third notch 15, which facilitates the insertion and removal of the card. Example 9:

[0041] like Figures 17-18 As shown, the difference from Embodiment 1 is that Embodiment 9 further provides a sealing port 16 at the opening of the card slot 11 of the inner card sleeve 10, and seals the sealing port 16 with a sealing strip 17 to improve the protection of the card.
