Description

Technical Field

[0001] This utility model relates to the field of stationery storage technology, specifically a portable pen end storage bag designed for stationery tools such as calligraphy brushes. Background Technology

[0002] In the use of stationery products, the calligraphy brush, as an important writing tool, usually needs to be cleaned after use. However, most calligraphy brushes on the market currently come with disposable caps, leaving the brush tip wet after washing. When users store the cleaned brushes in the product packaging, traditional stationery sets have a significant lack of proper storage structure.

[0003] This deficiency has led to a series of adverse consequences. On the one hand, water stains from the brush tip cannot be effectively contained, easily spreading to the packaging bag and other products inside, causing contamination. On the other hand, during storage, the wet brush inevitably stains paper and other items. These problems not only affect the tidiness of the stationery products' storage but also bring many inconveniences to users, reducing the user experience. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a portable storage bag that can effectively block water stains from brushes, prevent paper from getting dirty, and improve the convenience and tidiness of storage.

[0005] The technical solution of this utility model is to provide a portable storage bag, including a bag body, wherein a wet area isolation bag for accommodating a calligraphy brush is provided inside the bag body, and a first opening is provided on one side of the wet area isolation bag, wherein the first opening is in communication with the inner cavity of the bag body.

[0006] Compared with the prior art, the portable storage bag of this utility model has the following advantages: a wet zone isolation bag with a first opening and connected to the inner cavity of the bag is set inside the bag. The cleaned brush can be placed in the wet zone isolation bag. The isolation bag can separate the brush from other items in the bag, effectively preventing water stains from the brush from contaminating the packaging bag and other items. At the same time, the opening design makes it easy to put the brush in and take it out, improving the neatness and convenience of storing stationery.

[0007] As an improvement, the wet zone isolation bag is fixedly connected to the inner surface of the bag body, and the opening is fastened by a snap-on assembly. With this structure, the snap-on design ensures that the wet zone isolation bag tightly covers the brush, effectively securing it to prevent it from slipping out during storage. At the same time, it leaves a ventilation gap as a vent to ensure air circulation, preventing excessive humidity from causing the brush to mold and smell bad. This achieves both secure storage and ventilation / moisture protection.

[0008] As an improvement, the wet zone isolation bag is used to hold the brush tip, and a second opening is provided on the other side of the wet zone isolation bag for the brush handle to pass through. This structure allows for separate storage of the brush tip and handle, keeping the wet brush tip alone in the isolation bag, effectively preventing water stains from contaminating other items inside the bag. Simultaneously, the brush handle can be naturally placed through the second opening, ensuring the stability and integrity of the brush storage. This satisfies the need for dry and wet separation and makes it convenient for users to retrieve and put away the brush.

[0009] As an improvement, the length of the wet zone isolation bag is 8-11 cm. With this structure, this size can completely cover the brush tip of a regular-sized brush, ensuring that the wet brush tip is effectively isolated and preventing water stains from contaminating other items inside the bag. It can also accommodate brush tips of different lengths, avoiding inconvenience caused by the isolation bag being too long or too short. At the same time, the compact size design does not take up too much space inside the bag, ensuring the portability of the brush end storage bag, and achieving a balance between storage functionality and space utilization.

[0010] As an improvement, the bag body includes a pen tail storage bag for accommodating the pen tail. This pen tail storage bag has a third opening, which is positioned opposite the second opening. With this structure, after the pen handle extends through the second opening, the pen tail is precisely positioned in the corresponding pen tail storage bag, forming a fixed storage structure for both the pen head and the pen tail. This not only achieves independent isolation of the wet area of ​​the pen head through the wet zone isolation bag, but also enhances the overall stability of the pen storage with the pen tail storage bag, preventing the pen head from shifting and contaminating other items due to pen handle movement. Furthermore, the fixed design at both ends adapts to the natural shape of the pen.

[0011] As an improvement, the pen tail storage bag has at least one positioning cavity, which is interconnected with the third opening. With this structure, the positioning cavity can precisely lock the pen tail in place. Combined with the relative placement of the third and second openings, this achieves complete positioning and fixation of the pen from tip to tail. This prevents the pen tail from shifting within the storage bag and enhances the stability of the pen tail storage through the positioning cavity's design, ensuring that the wet pen tip remains within the wet zone isolation bag and avoiding water stains caused by pen movement.

[0012] As an improvement, the length of the pen tail storage bag is 4-11 cm; the width of the positioning cavity is 1-2 cm. This structure allows for the adaptation of different pen tail lengths and thicknesses, ensuring the pen tail is stably embedded in the positioning cavity, forming a precise fixing structure from the pen tip to the pen tail, preventing the pen from shifting or shaking during storage. Furthermore, the compact design reduces the space occupied by the pen tail storage bag, ensuring portability. The 1-2 cm positioning cavity width tightly fits the pen tail, avoiding instability due to excessive width or difficulty in retrieval due to excessive narrowness, thus achieving storage stability, space utilization, and ease of use.

[0013] As an improvement, the wet zone isolation bag is located at the top of the bag body, and the pen tail storage bag is located at the bottom of the bag body. With this structure, the brush tip can be placed naturally with the pen tail facing upwards, conforming to the soft characteristics of the brush tip and avoiding damage to the brush tip caused by pressure and bending due to inversion; at the same time, the top wet zone isolation bag can accurately store the wet brush tip, and the bottom pen tail storage bag can fix the pen tail, forming a stable vertical storage structure at both ends. It not only prevents water stains from contaminating other items through dry and wet separation, but also protects the shape of the brush tip by utilizing the natural downward hanging state of gravity, ensuring that the brush tip remains straight during storage.

[0014] As an improvement, the bag body includes a bottom box and a lid. The wet area isolation bag and the pen tail storage bag are both fixedly connected to the inner wall of the bottom box and located on the side of the bottom box. The lid covers the bottom box. With this structure, a closed storage space can be formed by the snap-fit ​​of the bottom box and the lid, effectively protecting the brush from external pressure. The side-fixed isolation bag and pen tail storage bag allow the brush to be stored in a side-standing position, preventing the brush tip from bending due to pressure from lying flat. At the same time, the side layout makes reasonable use of space, making it easy for users to intuitively take out and put away the brush.

[0015] As an improvement, the side of the base box is connected to the side of the lid, and the top, bottom, and another side of the base box are connected to the top, bottom, and another side of the lid via zippers. This structure allows the lid to open and close around the side, achieving a three-sided seal via the zippers. This creates a completely enclosed storage space, effectively preventing the brush from slipping out during transport or allowing external dust to enter. The flexible opening and closing of the zippers also allows users to quickly retrieve and place the brush from three sides, improving ease of use.

[0016] As an improvement, the wet zone isolation bag is made of PVC material. With this structure, PVC material has excellent waterproof performance, which can effectively prevent water stains from penetrating the brush tip and avoid contaminating other stationery items inside the bag; at the same time, the material is flexible and wear-resistant, which can provide cushioning protection for the soft brush tip during storage and prevent the brush tip from bending and deforming due to pressure.
