Abstract
Description
Technical Field
[0001] This utility model particularly relates to a screw-on candy box with a limiting step. Background Technology
[0002] Existing screw-on candy boxes typically use a disc-shaped lid that fits into a base, with the candy dispenser opening and closing by rotating the lid. However, this type of structure has the following drawbacks:
[0003] The top cover and base are positioned solely by friction or a simple protrusion-groove fit, lacking a mechanical stop at the rotation endpoint. Users often struggle to perceive the position when operating with one hand, frequently resulting in misalignment or even detachment of the top cover due to over-rotation, leading to a poor user experience. Furthermore, the top cover, held stationary by minimal friction, is highly susceptible to rotation under carrying, shaking, or gravity, causing the candy dispensing opening to open unexpectedly and spilling. Utility Model Content
[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a screw-on candy box with a limiting step.
[0005] To solve the aforementioned technical problems, this utility model adopts the following technical solution:
[0006] A screw-on candy box with a limiting step includes a base and an inner cover. The base and the inner cover together form a candy cavity. The inner cover has a candy dispensing opening communicating with the candy cavity. The inner cover has a limiting step with an arc segment and a tapering pointed segment. The pointed segment tapering from the arc segment forms a sharp point. An upper cover is fitted onto the limiting step. The upper cover can only rotate around the limiting step. When the inner wall of the upper cover rotates forward to abut the sharp point, the upper cover stops rotating due to the sharp point, and the candy dispensing opening is fully exposed. When the upper cover rotates in the opposite direction and returns to its original position, the candy dispensing opening is completely covered by the upper cover.
[0007] Preferably, the inner cover is provided with elastic protrusions, which abut against the upper cover to generate frictional resistance between the upper cover and the limiting step, thereby preventing the upper cover from rotating on its own under the action of gravity.
[0008] Preferably, the inner wall of the top cover is provided with a movable groove that matches the shape of the limiting step. The limiting step is rotatably embedded in the movable groove, and the contour of the movable groove maintains a clearance fit with the limiting step so that the top cover can rotate smoothly along the limiting step and be stopped by the tip at the end of the rotation.
[0009] Preferably, the limiting step is a teardrop-shaped structure that is narrow at the top and wide at the bottom, and the two sides of the pointed section are symmetrically curved, so that the top cover is stopped when it rotates to contact the tip, and can be reset to cover the sugar dispensing opening when rotated in the opposite direction.
[0010] Preferably, at least three positioning blocks are evenly distributed around the lower end of the inner cover, and an arc-shaped part is correspondingly provided on the upper inner wall of the base. When the inner cover and the base are closed, the arc-shaped part is engaged in the slot formed by the positioning blocks and the lower end of the inner cover, forming a circumferential fixed connection.
[0011] The beneficial effects of this utility model are:
[0012] This invention utilizes the rigid stop formed by the tip of the limiting step and the inner wall of the upper cover's movable groove. The upper cover can only rotate to the angle where the candy dispensing opening is exposed in the opening direction. This avoids over-rotation leading to misalignment or detachment, and eliminates the hassle of users having to feel for the end point, truly achieving one-handed "one-twist-to-the-end" operation. Furthermore, the elastic protrusions on the inner cover continuously apply pressure to the upper cover, generating stable frictional resistance. This prevents accidental opening caused by gravity rotation or other external forces during transportation, without affecting smooth operation. Attached Figure Description

[0024] A screw-on candy box with a limiting step includes a base 1 and an inner cover 2. The base 1 and the inner cover 2 together form a candy cavity. The inner cover 2 has a candy dispensing opening 3 communicating with the candy cavity. The inner cover 2 has a limiting step 4, which has an arc segment 41 and a pointed segment 42 that tapers from the arc segment 41 to form a tip 1-1. An upper cover 5 is fitted onto the limiting step 4. The upper cover 5 can only rotate around the limiting step 4. When the inner wall of the upper cover 5 rotates in the forward direction to abut the tip 1-1, the upper cover 5 stops rotating due to the stop of the tip 1-1, and the candy dispensing opening 3 is fully exposed. When the upper cover 5 rotates in the reverse direction and returns to its original position, the candy dispensing opening 3 is completely covered by the upper cover 5.
[0025] Furthermore, the inner cover 2 is provided with elastic protrusions 6, which abut against the upper cover 5 to generate frictional resistance between the upper cover 5 and the limiting step 4, thereby preventing the upper cover 5 from rotating on its own under the action of gravity.
[0026] Furthermore, the inner sidewall of the upper cover 5 is provided with a movable groove 51 that is adapted to the shape of the limiting step 4. The limiting step 4 is rotatably embedded in the movable groove 51. The contour of the movable groove 51 is in clearance fit with the limiting step 4 so that the upper cover 5 can rotate smoothly along the limiting step 4 and be stopped by the tip 1-1 at the end of the rotation.
[0027] Furthermore, the limiting step 4 is a teardrop-shaped structure that is narrow at the top and wide at the bottom, and the two sides of the pointed section 42 are symmetrically curved, so that when the upper cover 5 rotates to contact the tip 1-1, it is stopped, and when it rotates in the opposite direction, it can be reset to cover the sugar dispensing opening 3.
[0028] Furthermore, at least three positioning blocks 7 are evenly distributed around the lower end of the inner cover 2, and an arc-shaped part 71 is correspondingly provided on the upper inner wall of the base 1. When the inner cover 2 and the base 1 are closed, the arc-shaped part 71 is inserted into the slot formed by the positioning blocks 7 and the lower end of the inner cover 2, forming a circumferential fixed connection.
[0029] The working principle of this utility model is as follows:
[0030] like Figure 1 As shown, the screw-on candy box of this embodiment includes a base 1, an inner cover 2, and an upper cover 5. When the base 1 and the inner cover 2 are closed, a candy cavity is formed for holding candy. A candy dispensing opening 3 is provided on the inner cover 2, and the opening 3 communicates with the candy cavity. A limiting step 4 is integrally formed on the upper surface of the inner cover 2. The limiting step 4 has a teardrop-shaped structure, and the shape of its arc segment 41 matches the inner wall of the movable groove 51 of the upper cover 5. The pointed segment 42 gradually tapers from the arc segment 41 to form a pointed tip 1-1. The upper cover 5 is fitted onto the outer periphery of the limiting step 4 through the movable groove 51 and can rotate around the limiting step 4. The outer periphery of the limiting step 4 is composed of two arc segments 41 and two tapering pointed segments 42. The arc segments 41 provide a continuous sliding surface to ensure smooth rotation. When the corresponding inner wall of the movable groove 51 touches the tip 1-1, the wedge-shaped contraction on both sides of the tip 1-1 results in a greater wedge tightening force as it rotates forward. The tip 1-1 acts as a rigid stop to prevent the upper cover 5 from continuing to rotate, at which point the sugar dispensing opening 3 is fully exposed.
[0031] When the user rotates in the opposite direction, the other end face of the active groove 51 disengages from the tip 1-1, and the continuous curved surface of the arc segment 41 provides a smooth return path; after the top cover 5 returns to the initial position, the sugar dispensing port 3 is completely covered.
[0032] like Figure 1 and Figure 2 As shown, when the user rotates the top cover 5 clockwise (positive direction) until its inner wall abuts against the tip 1-1, the tip 1-1 stops the top cover 5, and the sugar dispensing port 3 is fully exposed, making it convenient to take out sugar; when the user rotates the top cover 5 in the opposite direction to reset it, the sugar dispensing port 3 is completely covered by the top cover 5, achieving a seal.
[0033] like Figure 5 As shown, the inner cover 2 is also provided with elastic protrusions 6, which abut against the lower surface of the upper cover 5 to generate moderate frictional resistance and prevent the upper cover 5 from rotating on its own under gravity or shaking.
[0034] like Figure 5 As shown, the two sides of the tip 1-1 transition with symmetrical arcs to ensure a smooth stop without jamming.
[0035] like Figure 3 As shown, at least three positioning blocks 7 are evenly distributed around the lower end of the inner cover 2, and an arc-shaped part 71 is correspondingly provided on the upper inner wall of the base 1. When the inner cover 2 and the base 1 are closed, the arc-shaped part 71 is inserted into the slot formed by the positioning blocks 7 and the lower end of the inner cover 2, forming a circumferential fixed connection.
[0036] This invention utilizes the rigid stop formed by the tip of the limiting step and the inner wall of the upper cover's movable groove. The upper cover can only rotate to the angle where the candy dispensing opening is exposed in the opening direction. This avoids over-rotation leading to misalignment or detachment, and eliminates the hassle of users having to feel for the end point, truly achieving one-handed "one-twist-to-the-end" operation. Furthermore, the elastic protrusions on the inner cover continuously apply pressure to the upper cover, generating stable frictional resistance. This prevents accidental opening caused by gravity rotation or other external forces during transportation, without affecting smooth operation.
[0037] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
