Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of container sealing, in particular to a container cover. Background Art
[0002] When the container is in use, the upper part is sealed by a screwed-on cover. At the same time, in order to ensure that the container is not used or stolen before it reaches the actual user after leaving the factory, a corresponding anti-theft ring is provided on the lower side of the cover. When the cover is installed, it is fitted on the container mouth. When the cover is unscrewed and removed, the cover and the anti-theft ring are broken, so that the anti-theft ring remains at the container mouth.
[0003] However, in actual use, when the container is large, the thickness of the anti-theft ring itself is relatively large. During installation, the anti-theft ring needs to be squeezed to engage it with the container mouth. However, the thicker anti-theft ring engaging structure is easy to be rigidly squeezed with the engaging part of the container mouth, causing the container mouth to be deformed and damaged or the anti-theft ring to be damaged, thus affecting normal use. Moreover, squeezing can easily cause the container mouth position to be deformed due to coordinated force, thus affecting the mechanical properties and strength of the container mouth position. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a container cover in view of the above-mentioned technical deficiencies, wherein an anti-theft ring is matched with the cover body. When the cover is closed, the protrusion on the inner side of the anti-theft ring is fitted into the locking position of the container mouth along the second inclined wall, and the transition effect of the inclined surface makes it easier for the anti-theft ring to fit into place, thereby avoiding the problem that excessive pressure during hard pressurization may easily cause deformation and damage of the container, thereby affecting the mechanical properties. The intermittent threads arranged inside the cover body are matched with the beveled surface, and the weight of the cover body is reduced by the setting of the intermittent threads. Furthermore, the setting of the beveled surface makes it easier to screw into place even if the threads are intermittent, thereby avoiding the problem that the threads of the container mouth are easily damaged when the intermittent threads are screwed together directly. At the same time, reinforcing ribs are arranged on the outside of the cover body to enhance the friction of the cover body, thereby making it easier to bear force when the cover is screwed on, thereby avoiding the problem of slipping.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: it includes a cover body; an opening is set on one side of the cover body; the cover body is connected to the anti-theft ring through intermittently set connecting strips on all sides; the inner side of the anti-theft ring is provided with a protrusion for clamping at the container mouth position; the cover body is provided with an intermittent thread for rotating and fixing the container.
[0006] To further optimize the technical solution, the radial width of the connecting strip is smaller than the anti-theft ring.
[0007] To further optimize the technical solution, a first inclined wall is provided on the side of the protrusion axially close to the cover body; and a second inclined wall is provided on the side of the protrusion axially away from the cover body.
[0008] To further optimize the technical solution, the inclination angle between the second inclined wall and the surface of the anti-theft ring is set smaller than the inclination angle between the first inclined wall and the surface of the anti-theft ring.
[0009] To further optimize the technical solution, reinforcing ribs are arranged at intervals around the outer wall of the cover.
[0010] To further optimize the technical solution, the reinforcing ribs are arranged equidistantly along the axial direction.
[0011] To further optimize the technical solution, the discontinuous thread comprises a plurality of discontinuous thread segments; each of the thread segments is provided with inclined transition bevel surfaces on both sides of the circumference.
[0012] To further optimize the technical solution, the thread segments are arranged at intervals along the thread direction and arranged in an axial direction, and the multiple thread segments are arranged at intervals along the circumferential direction as a whole.
[0013] To further optimize the technical solution, the multi-segment thread is arranged in three sections along the circumferential direction as a whole.
[0014] Compared with the prior art, the utility model has the following advantages: 1. The anti-theft ring cooperates with the cover body, and this structure advantageously ensures that when the cover is closed, the anti-theft ring is easier to fit into place by fitting the inner protrusion of the anti-theft ring along the second inclined wall to the locking position of the container mouth through the transition effect of the inclined surface, thereby avoiding the problem that the container is easily deformed and damaged by excessive pressure during hard pressurization, thereby affecting the mechanical properties; 2. The intermittent threads arranged inside the cover body cooperate with the beveled surface, and this structure advantageously ensures that the weight of the cover body is reduced by setting the intermittent threads, and further, by setting the beveled surface, even if the threads are intermittent, it is easier to screw into place, thereby avoiding the problem that the threads of the container mouth are easily damaged when the intermittent threads are screwed together directly; 3. The reinforcing ribs arranged outside the cover body are adopted, and this structure advantageously ensures that the friction of the cover body is enhanced, so that when the cover is screwed on, it is easier to bear the force and avoid the problem of slipping.

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.
[0020] Specific implementation method: Combination Figure 1-3 As shown, it includes a cover body 1; an opening is set on one side of the cover body 1; the cover body 1 is connected to the anti-theft ring 3 through an intermittent connecting strip 2 around it; a protrusion 4 for being stuck in the container mouth position is set on the inner side of the anti-theft ring 3; an intermittent thread 5 for rotating and fixing the container is set in the cover body 1; the radial width of the connecting strip 2 is smaller than that of the anti-theft ring 3; a first inclined wall 6 is set on the side of the protrusion 4 axially close to the cover body 1; a second inclined wall 7 is set on the side of the protrusion 4 axially away from the cover body 1; the inclination angle between the second inclined wall 7 and the surface of the anti-theft ring 3 is smaller than the inclination angle between the first inclined wall 6 and the surface of the anti-theft ring 3; reinforcing ribs 8 are set at intervals around the outer wall of the cover body 1; the reinforcing ribs 8 are set at equal distances along the axial direction; the intermittent thread 5 includes a plurality of intermittent thread segments 9; each of the thread segments 9 is provided with an over-inclined chamfered surface 10 on both sides of the circumference; the thread segments 9 are arranged at intervals along the thread direction and arranged in an axial direction, and the plurality of thread segments 9 are arranged at intervals along the circumferential direction as a whole; the plurality of thread segments are arranged at intervals of three sections along the circumferential direction as a whole.
[0021] Combination Figure 1-3 As shown, when in use, the more inclined second inclined wall 7 makes it easier to fit the container cover during screwing and installation, thus avoiding the problem that the too-hard anti-theft ring 3 is rigidly pressed against the container mouth during installation, which may easily cause the peripheral position of the container mouth to deform and affect the mechanical properties. During the screwing and installation and removal process, the discontinuous thread 5 achieves the effect of a full thread. At the same time, the setting of the beveled surface 10 makes the thread segment 7 smoother when screwed in, thus avoiding the problem that the hard straight surfaces are pressed against each other and the thread of the container mouth is damaged. At the same time, during the screwing and installation and removal, the setting of the reinforcing ribs 8 makes it easier to cooperate with the hand movements when twisting, thereby increasing the friction of the cover body 1.
