Low profile construction with integral gusset and raised bottom compartment

Abstract

To provide a thin storage structure that can store contents in an organized manner while maintaining a thin profile by solving the problems of conventional structures, such as difficulty in taking in and out bills when a large number of bills are stored, and the storage section expanding due to the accumulation of cards, coins, and keys. [Solution] The exterior member 1 is folded from a single piece of material, and a U-shaped gusset section 3 is integrally formed to form a banknote storage space. The gusset section expands depending on the thickness of the contents, allowing for a large number of banknotes 7 to be stored and easily removed. Furthermore, an interior structure 2 formed by an extension of the exterior member is provided with a raised card storage section 4, and a coin storage section 6 and key storage section 5 are compartmentalized and positioned below it to prevent interference between the contents. A contact prevention section 12 formed by an extension of the exterior member is provided on one side of the opening edge 11 to prevent banknotes from coming into contact with or getting caught in the zipper, achieving both efficient storage and a slim design.

Description

[Technical Field]

[0001] This invention relates to a wallet or other portable storage device that can store multiple items such as bills, cards, coins, and keys in a slim design, and in particular to the U-shaped gusset portion formed integrally with the exterior member and the layout structure of the internal storage area. [Background technology]

[0002] Although conventional small wallets have small external dimensions, they have the problem of increasing thickness due to overlapping contents and components. In recent years, there have been products that claim to be thinner, but in reality, most of them sacrifice storage capacity. In particular, it is rare to find a structure that can store a large amount of banknotes while maintaining a thin design, and in which the exterior and interior are formed continuously from a single piece of material. Summary of the Invention [Problem to be solved by the invention]

[0003] The problem that this invention aims to solve is that with conventional small wallets with a gusset structure, it can be difficult to take in and out bills when a large amount of bills are stored, and the entire storage area becomes unnecessarily bulging, making it difficult to use. The purpose of this invention is to provide an internal layout structure that allows smooth insertion and removal even when a large amount of bills are stored, and that can optimally arrange contents such as cards, coins, and keys to prevent the thickness of the storage area from increasing. [Means for solving the problem]

[0004] Unlike conventional separate side gussets, this device forms the entire interior structure (partition member) from a single piece of material, creating a U-shaped gusset on the side of the bill storage space (Claim 1). This allows the gusset to naturally flex even when bills are inserted deep inside, preventing the overall thickness of the storage compartment from increasing and allowing for smooth insertion and removal of bills.

[0005] Furthermore, an interior structure (partition member) positioned on the extension of the gusset portion forms a raised card storage section, with the coin storage section and key storage section partitioned and arranged below it (Claim 2). The card storage section has notches at the ends to make it easy to insert multiple cards deep inside, and the coin storage section is arranged on a separate layer from the card storage section to minimize interference between the contents. The key storage section has a cylindrical gap and is designed to allow keys to be inserted and held from the side, making it difficult for cards and keys to overlap each other, and achieving a slim design while functioning as a base for the interior structure.

[0006] In addition, a contact prevention section formed by extending the exterior member is provided on only one side of the opening end of the storage section to prevent contact between banknotes and opening / closing members such as zippers. The contact prevention section has edge treatment according to the material, which can prevent banknotes from getting caught. [Effects of the Invention]

[0007] In this device, the U-shaped gusset formed integrally with the exterior member ensures sufficient depth for the bill storage space, making it possible to safely store a large number of bills. Furthermore, the gusset is designed to autonomously expand and retract depending on the thickness of the contents, making it easy to insert and withdraw bills.

[0008] Furthermore, in the interior structure located on the extension of the gusset, the bottom of the card storage section is raised and the coin storage section is partitioned and located below it, so cards and coins can be stored in an organized manner without interfering with each other, improving visibility and ease of access to the contents and ultimately contributing to a slim overall design. Also, by making the ends of the card storage section notched, cards can be inserted deeper, improving storage efficiency.

[0009] The key storage section is integrated into the support pillar of the interior structure that separates the coin storage section. This key storage section has a cylindrical gap that allows keys to be inserted from the side, making it possible to effectively utilize the storage space while also allowing keys to be easily inserted and removed from the front when in use, improving operability.

[0010] Furthermore, the contact prevention section provided on one side of the opening end of the storage section prevents banknotes from coming into contact with opening and closing members such as zippers, making it easier to avoid banknotes getting caught and contributing to compactness.

[0011] By continuously forming the exterior components and interior structure from a single piece of material, the sewing process can be eliminated, resulting in reduced manufacturing costs and a lighter product.

[0012] Furthermore, the structure of this invention can be applied to a variety of shapes, including bifold, long wallet, key case, and pochette, and can be easily expanded to materials other than leather, such as synthetic resin and fabric, making it highly versatile and applicable. It can also be incorporated into a key holding structure, which is currently under patent application. [Brief explanation of the drawings]

[Figure 3] FIG. 3 is a perspective view (structural explanatory diagram) of FIG. 1 with the contents omitted. [Figure 4] FIG. 4 is a front view showing the overlapping state of the contents. DETAILED DESCRIPTION OF THE INVENTION

[0014] This embodiment is a thin structure that allows smooth insertion and removal even when a large amount of banknotes are stored, and furthermore, by optimally arranging cards, coins, and keys, it prevents the thickness of the storage section from increasing. The specific configuration of this invention will be described below with reference to Figures 1 to 4. [Example]

[0015] This embodiment shown in Figure 1 (perspective view: with contents) and Figure 2 (top view) is in the form of a bifold wallet. The exterior member (1) is made of a single piece of flexible material, with its side edges continuously curved and a gusset section (3) integrally formed on the inside to form a space for storing banknotes. The gusset section expands and returns to its original shape depending on the thickness of the contents, allowing for smooth insertion and removal of banknotes even when a large amount of banknotes is stored without increasing the overall thickness of the storage section.

[0016] As shown in Figure 2 and Figure 3 (with the contents omitted), the material extended from the exterior member (1) forms the interior structure (2) continuously without folding or stitching, so it is clearly visible that the exterior and interior are made of a single piece of material.

[0017] The bill storage space of this structure can hold more than 20 folded bills, and it has been confirmed that in long wallet form (when bills are stored unfolded) it can easily hold roughly twice that amount.

[0018] The interior structure (2) is divided into a card storage section (4) on the upper level and a key storage section (5) on the lower level. The edges of the card storage section are notched, allowing for easy removal of multiple cards even when inserted all the way to the back. The coin storage section (6) is located on a separate layer from the card storage section, preventing interference between the contents and contributing to a slim design.

[0019] The key storage section (5) has a cylindrical gap and is designed to hold the key inserted from the side. This makes effective use of the internal space while allowing the key to be easily inserted and removed from the front, improving operability. The key storage section also functions as a support for the interior structure (2), reinforcing the overall rigidity.

[0020] A contact prevention section (12) is formed on one side below the opening of the storage section to prevent contact between banknotes and opening / closing parts such as zippers. The edges are treated according to the material, such as with edge finishing, heat welding, or binding, to ensure durability.

[0021] While this embodiment illustrates a bifold wallet, it can also be applied to long wallets, trifold wallets, key cases, and other shapes by changing the length and folding position of the exterior member (1). The material is not limited to leather; it can be replaced with synthetic resin or fabric. Furthermore, a key holding structure, which is currently under patent application, can be incorporated outside the gusset, and the present invention is applicable to these modifications as well. The contact prevention section can also be omitted if necessary.

[0022] As shown in the front view of Figure 4, the card storage section (4) and the coin storage section (6) are clearly separated from each other above and below, and it can be seen that the cards and coins are arranged so as not to overlap each other as much as possible. [Industrial Applicability]

[0023] The slim storage structure of this invention can be applied to various portable storage items such as wallets, key cases, card cases, mobile pouches, and mini pochettes, and can be easily incorporated into mass production lines that use synthetic resins and fabrics. [Explanation of symbols]
