Description of the Invention: [Technical Field of the Invention] The present invention relates to a toner cartridge for collecting waste toner, and more particularly to a toner cartridge which avoids loosening of a round cover of a sealed waste toner. [Prior Art] Please refer to the conventional toner cartridge (10) shown in the first figure, which mainly includes a Φ box (12) and a plurality of domes (14). One of the side walls (122) of the casing (12) has a plurality of U-shaped recesses (124), and each U-shaped recess (124) is defined by a bottom wall (16') and a U-shaped peripheral wall (18), wherein The dome-shaped peripheral wall (18) has a flange (182) having an arc segment (184) and two straight segments (186" each extending from the ends of the arc segment (184) (14) Having a head (142) and a body (144) extending axially from the head (142), the body (144) is received in one of the yoke slots (124) and abuts the flange (182), as shown in the second figure. When the toner cartridge (10) completes the collection of waste toner, the dome can be removed from the tank (124) and inserted into the toner cartridge (1〇). a circular hole (126) in the top wall for sealing the waste toner in the toner cartridge (1〇). However, as shown in the second figure, due to the outer portion (144) of the dome (14) The diameter is smaller than the distance between the two straight segments (186) of the flange (182), so that the dome (14) is easily detached from the open end of the U-shaped groove (124), and the body of the round cover (14) The radius of (144) is approximately equal to the radius of curvature of the arc (184) of the flange (182), resulting in a round cover (14) Disengaging the U-shaped recess (124) in the direction of the vertical bottom wall (16). Therefore, the user usually uses a tape to adhere the dome (14) to prevent the dome (14) from falling off, but it must 3 1364634 ', ν · - . · ν'. . . . ; ; '1 : '1· ' - ., · ·· ....-'1 ·, . . 1 .t invention content The main purpose of the present invention is to provide a toner cartridge which can provide a good fixing effect of the round file and can be easily taken by the user to increase the convenience of use. To achieve the above object, the toner cartridge of the present invention The utility model comprises a box body and a round cover. The box body has a first (fourth), a first side wall adjacent to the first side wall, a bottom wall, and a peripheral wall, wherein the bottom wall is covered by the first side wall The surface is recessed and abuts the second side wall, the peripheral wall connecting the first side wall and the bottom wall, such that a gap is formed between the closing wall and the bottom wall, and the peripheral wall protrudes in the direction of the trough a flange having an arc segment and two limit segments extending from both ends of the arc segment. The dome has a head and an axial direction from the head An extended body portion and an anchor portion extending axially from an end of the body portion, the body portion being received in a pocket of the casing and adjacent to an arc of a flange of the peripheral wall, wherein the body portion The outer diameter is greater than the spacing between the two limiting segments of the flange, such that the dome cannot easily disengage from the pocket in a direction parallel to the second limiting segment, and the radius of the anchor portion is greater than the flange The radius of curvature of the arc segment is such that the dome cannot easily disengage from the pocket in a direction perpendicular to the bottom wall. [Embodiment] In order to explain the structure, features and effects of the present invention in detail, a preferred embodiment will be described with reference to the following drawings. 4 [S] 1364634 Referring to a third embodiment, a toner cartridge (20)' provided by a preferred embodiment of the present invention includes a casing (3 turns) and a plurality of domes (4 turns). Please refer to the fourth to fifth figures. The box body (3〇) has a plurality of round holes (31), which can be used to collect the waste toner and collect the waste toner into the interior. The casing (3〇) has a first side wall (32), a second side wall (33), a bottom wall (34), and a peripheral wall (35), wherein the second side wall (33) abuts the first side a wall (32); the bottom wall (34) is recessed by a surface of the first side wall (32) and abuts the second side wall (33); the peripheral wall (35) connects the first side wall (32) and the bottom wall (34) a groove (36) is defined between the peripheral wall (35) and the bottom wall (34), and a peripheral flange (37) projects a flange (37) in the direction of the receiving groove (36), the flange ( 37) having an arc segment (372) and a second limit segment (374), the central angle (0) formed by the arc segment (372) is greater than ι8〇, and the second limit segment (374) is formed by the arc segment (372) Both ends extend linearly and are parallel to each other. Referring to Figures 4 to 6, each dome (4〇) has a head (42), a body (44) extending axially from the head (42), and a body (44) end An axially extending anchor portion (46), wherein the body portion (44) is received in the pocket (36) of the casing (30) and adjacent to the arc of the flange (37) of the peripheral wall (35) (372) ). The outer diameter (R) of the body (44) is greater than the spacing (D) between the two limit segments (374) of the flange (37), and the radius (ri) of the anchor portion (46) is greater than the flange (37) The radius of curvature of the arc segment (372) (6). Referring to Figures 4 to 7, the radius (rl) of the wrong portion (46) of the dome (4) is larger than the radius of curvature (r2) of the arc (372) of the flange (37), so that the dome ( 40) When the tank (36) is to be loaded, a predetermined force must be applied to force the anchor (46) of the dome (40) to deform along with the body (44) until the anchor of the dome (4〇) 5 1364634 After passing through the arc (372) of the flange (37), the portion (46) will return to its original shape and at the same time produce a snapping effect. Thus, the dome mounted behind the pocket (36) 40) It will not fall out of the pocket (36) in the direction of the vertical bottom wall (34). On the other hand, 'the outer diameter (R) of the body (44) of the dome (40) is larger than the spacing (D) between the limit segments (374) of the flange (37), so that it is mounted in the pocket ( 36) The rear dome (40) does not fall directly through the open end of the pocket (36), but must also exert a predetermined force to force the dome (4...the body (44) to deform] so that The body (44) of the dome (40) can pass through the two limiting sections (374) of the flange (37), so that the dome (4) can be removed from the pocket (36) and inserted into the box (30) Round hole (31). According to the above design, the toner cartridge of the present invention can make the round cover fixed in the casing without the lining, which is not only easy to call, but also convenient to take. If the stipulations must be made through the tape (4), the convenience of use can be increased. According to the spirit of the present invention, the structure of the present invention can be variously changed, for example, the two limit segments of the flange can be parallel or oblique to each other. It is not necessary to have a straight extension #, as long as the minimum spacing of the two limiting segments of the flange is smaller than the outer diameter of the body of the dome. The invention is disclosed in the foregoing embodiments. The components are only 1 child, and the system is closed to the scope of the case. For other equivalent trees, the silk edge of the equivalent tree should also be covered by the patent fan. - 1364634 Simple illustration of the schema] The first picture is the custom The second figure is a partial cross-sectional view of a conventional toner cartridge.
