Description

Technical Field

[0001] This utility model relates to the field of toothpick box technology, and in particular discloses a portable toothpick box. Background Technology

[0002] Toothpicks are a common oral hygiene tool in daily life, and toothpick boxes are essential containers for storing them. However, existing toothpick boxes have many shortcomings. Some toothpick boxes have a simple structure, and the connection and opening / closing of the lid and body are not convenient enough. They are either difficult to open and close, affecting the user experience, or they have poor sealing, making it easy for toothpicks to get damp and dusty. Some toothpick boxes lack a reasonable internal structure design, have a single function, and can only store toothpicks, failing to meet the diverse needs of users. Utility Model Content

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a portable toothpick box.

[0004] To achieve the above objectives, this utility model provides a portable toothpick holder, comprising a cylindrical body, a lid, a rotating part disposed on the cylindrical body, and a pivot disposed on the lid. The cylindrical body has an inner cavity for accommodating toothpicks from the outside. The cylindrical body includes a main body, a closing part disposed above the main body, and a first protrusion disposed outside the closing part. The lid has a second protrusion at one end near the main body. The lid is rotatably disposed on the rotating part of the cylindrical body via the pivot. When the lid rotates around the pivot to the closed position, the first protrusion and the second protrusion engage, and the lid covers the opening of the inner cavity to prevent toothpicks from falling out. When the lid rotates around the pivot to the open position, the first protrusion and the second protrusion disengage, and the lid opens to facilitate access to the toothpicks.

[0005] The opening and closing of the toothpick dispensing opening is achieved by rotating the cover around a pivot. Combined with the engaging / disengaging structure of the first and second protrusions, this ensures both a tight seal to prevent moisture or contamination of the toothpicks when closed and easy access for dispensing. The overall structure is simple, easy to operate, and suitable for portable use. Specifically, the tube has a main body, a cover, and a first protrusion on the outer side. One end of the cover has a second protrusion connected to the rotating part of the tube via a pivot. When the cover is rotated to the closed position, the first and second protrusions engage, and the bottom surface of the cover fits against the top surface of the cover, sealing the toothpick dispensing opening. When rotated to the open position, the two protrusions disengage, and the toothpick dispensing opening is opened for use.

[0006] The rotating shaft is a non-circular shaft with a polygonal cross-sectional shape. The rotating part includes a bearing seat disposed on the cover part. The bearing seat has a non-circular rotating groove that extends through the bearing seat axially. The inner side of the rotating groove is composed of multiple inner wall planes connected end to end. The side of the rotating shaft fits against the inner wall plane and slides along the inner wall plane during rotation.

[0007] The system employs a non-circular shaft with a rotating groove on a bearing seat featuring multiple sets of parallel inner wall planes. Through the contact and sliding fit between the side of the rotating shaft and the inner wall plane, the cover rotation is smoother and more stable, reducing shaking and wear, and extending service life. Simultaneously, it ensures accurate positioning of the cover in both closed and open positions, improving sealing and operational reliability. The overall structure is simple and compact, better suited to the design requirements of portable products. Specifically, the rotating shaft is a non-circular shaft with an axially penetrating rotating groove on the bearing seat of the rotating part. The bottom surface of the groove has multiple sets of strip-shaped ribs extending along the length direction, forming inner wall planes. Dividing lines are formed between adjacent inner wall planes. The cover is installed in the rotating groove via the non-circular shaft. During rotation, the side of the shaft contacts and slides along the inner wall plane, achieving smooth rotation and positioning of the cover.

[0008] The bearing seat has a notch, which is connected to the rotating groove. The rotating shaft of the cover is detached from the bearing seat of the cylinder through the notch.

[0009] The bearing seat has a notch parallel to the inner wall plane and connected to the rotating groove, allowing the rotating shaft of the cover to be easily assembled and disassembled from the bearing seat of the cylinder. This facilitates rapid assembly during production and also allows for easy disassembly, repair, and replacement in case of wear or malfunction during subsequent use, without affecting the stability and sealing of the cover during rotation. Specifically, the bearing seat has a notch parallel to the inner wall plane, which connects to the rotating groove. During assembly, the rotating shaft of the cover can be installed into the rotating groove of the bearing seat through the notch, and it can also be removed through the notch during disassembly, achieving convenient assembly and disassembly of the cover and cylinder.

[0010] The cover includes a front cover and a rear cover that is fitted together with the front cover. The front cover has a first slot on the side near the rear cover, and the rear cover has a first flange on the side near the front cover. The front cover is engaged with the first flange of the rear cover via the first slot.

[0011] The cover adopts a split structure with a front cover and a rear cover that fit together. The front cover is engaged with the first flange of the rear cover via a first slot. This not only facilitates the separate production of the front and rear covers using molds, reducing processing difficulty, but also ensures a tight connection between the two through the precise engagement of the flange and the slot, preventing loosening or detachment. Furthermore, when adjustments or repairs to the internal structure of the cover are needed, the front and rear covers can be easily separated for operation without affecting overall performance. Specifically, the cover consists of a front cover and a rear cover. The front cover has a first slot on the side closest to the rear cover, and the rear cover has a corresponding first flange. During assembly, the first slot of the front cover is aligned with the first flange of the rear cover, and pressure is applied to secure the two together, forming a complete cover.

[0012] The front cover has a first protrusion and a second protrusion located below the first protrusion on its inner side. The first protrusion and the second protrusion together form a first receiving chamber. The rear cover has a third protrusion and a fourth protrusion located below the third protrusion on its inner side. The third protrusion and the fourth protrusion together form a second receiving chamber. When the front cover and the rear cover are fitted together, the first receiving chamber and the second receiving chamber are connected to form a third receiving chamber. The toothpick holder also has a mirror, which is housed in the third receiving chamber.

[0013] The first and second protrusions on the inner side of the front cover form a first receiving chamber, while the third and fourth protrusions on the inner side of the rear cover form a second receiving chamber. When installed together, these two protrusions connect to form a third receiving chamber, providing a dedicated and stable space for the mirror. This protects the mirror from external impacts and scratches, while the closed structure of the cover prevents dust accumulation. Furthermore, this chamber design is compatible with the split structure of the cover, allowing for easy removal and placement of the mirror when assembling the front and rear covers. This adds a grooming function to the toothpick holder, enhancing its practicality and portability. When the front cover is fastened to the first slot of the rear cover via the first flange, the first and second receiving chambers connect to form the third receiving chamber, which houses the mirror. The mirror can then be easily accessed by opening and closing the cover.

[0014] The bottom of the cylinder is provided with an inclined guide surface, which is the bottom surface of the inner cavity.

[0015] The bottom of the tube is equipped with an inclined guide surface, which can guide the toothpicks inside the tube to gather towards the retrieval opening by using the tilt angle. This avoids toothpicks piling up messily inside the tube, which would make them difficult to retrieve. Especially when there are a few toothpicks, it can reduce problems such as "sticking" or "not being able to take them out" caused by a flat bottom, allowing users to obtain toothpicks more easily. At the same time, the inclined structure is integrated with the overall shape of the tube and will not increase the size of the product, making it suitable for portable design needs.

[0016] The outer side of the main body is provided with an outer prismatic structure extending along its axial direction, and the outer prismatic structure has multiple facets.

[0017] The outer side of the main body has an outer prismatic structure composed of multiple facets extending along the axis. Compared with a smooth cylindrical surface, the facets can increase the friction between the hand and the tube, effectively preventing slippage caused by wet hands or improper force during use, allowing users to hold the tube more firmly when picking up toothpicks. At the same time, the design of multiple facets gives the product a more layered appearance, improving the overall aesthetics and recognizability. Moreover, the prismatic structure extends along the axis, so it does not affect the portability of the tube, which is in line with the product's portable positioning.

[0018] The first protrusion has a first arc-shaped transition surface, and the second protrusion has a second arc-shaped transition surface.

[0019] The curved transition surface design further optimizes the smoothness of the lid's snap-on and snap-on action, while enhancing the structure's durability. The first curved transition surface on the first protrusion and the second curved transition surface on the second protrusion work together. When the lid is rotated to the closed position, the curved surface guides the two protrusions to complete the snap-on action more smoothly, reducing any jamming or friction during the snap-on process. When the lid is opened, the curved transition surface also reduces the resistance when the two protrusions disengage, making operation easier. In addition, compared to right-angle or acute-angle designs, the curved structure can disperse external impacts, reducing wear or breakage caused by frequent snap-on and snap-on actions during long-term use, extending the component's lifespan. Furthermore, the curved transition surface makes the product's appearance more rounded and refined, improving the user's tactile experience.

[0020] The end of the cover away from the main body is provided with an opening protrusion to facilitate the application of force.

[0021] The end of the cover away from the main body is provided with an opening protrusion for easy application of force, providing users with a clear point of force application. There is no need to search or fumble for the force application position. Just gently flick or press the opening protrusion to easily drive the cover to rotate around the rotating shaft, so that the first protrusion and the second protrusion can be smoothly separated, and the stencil opening can be quickly opened.

[0022] The cover has a sealing part protruding inward on the side near the cylinder, and a fifth protrusion is provided at the connection between the cover part and the main body part; when the cover is closed on the cylinder, the sealing part of the cover abuts against the fifth protrusion to seal.

[0023] A sealing part protrudes inward on the side of the cap near the body, and a fifth protrusion is provided at the connection between the cap and the main body. When the cap is closed on the body, the sealing part abuts against the fifth protrusion, forming an additional sealing barrier. This structure, together with the snap-fit ​​of the first and second protrusions, effectively prevents external moisture, dust, and other contaminants from entering the tube, avoiding toothpicks from getting damp, contaminated, or deteriorating. It significantly improves the preservation quality of toothpicks, especially in humid environments or during transport.

[0024] The beneficial effects of this utility model are as follows: This utility model achieves the opening and closing of the toothpick dispensing opening by the cover rotating around a non-circular axis within the rotating groove of the shaft seat, in conjunction with the engagement and disengagement of the first and second protrusions. All structures work synergistically. The overall structure is simple and compact, the cover rotates smoothly and accurately, and the opening and closing operation is convenient and effortless. The shaft seat notch design facilitates disassembly and maintenance, and the split structure of the cover reduces production difficulty and ensures a stable connection. The sealing part, the fifth protrusion, and the protrusions form a double seal, effectively preventing moisture and dust, and ensuring the quality of the toothpicks. The inclined guide surface at the bottom solves the problem of toothpick dispensing, and the outer prismatic structure improves grip stability and aesthetics. The built-in mirror expansion function further optimizes the user experience by opening the protrusions and the arc-shaped transition surface. The overall design is suitable for portable scenarios, combining practicality and durability. Attached Figure Description
