Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the utility model, belong to the scope of protection of the utility model.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

An embodiment of the present invention provides a packaging structure, including: a base 100 and a cover 200; the base body 100 comprises a base 110 and a cantilever 120, wherein the cantilever 120 is arranged on the base 110; the cover 200 includes a body portion 210 and a protrusion 220, the protrusion 220 is disposed on the body portion 210, the protrusion 220 is pivotally connected to the base 110, and the body portion 210 has a closed position, a first open position, and a transition position between the closed position and the first open position relative to the base 110.

Typically, the packaging structure is a container. The base 110 has a receiving cavity 115 to receive a target. The target substance may be cosmetic, or other articles such as medicine or jewelry. The state of the object is not limited to a block, powder, liquid, paste, or the like. Fig. 2 to 9 exemplarily show a schematic structure of a cosmetic powder compact.

As shown in fig. 2 and 4, the accommodating chamber 115 has an opening 1151 on a side facing the cover 200, and when the protruding portion 220 is in a closed position relative to the base 110, the main body portion 210 can cover the opening 1151 to prevent the target object in the accommodating chamber 115 from spilling out.

In the closed position, the angle between the base 100 and the cover 200 is approximately 0 °. In the closed position, the object in the container is not accessible. Fig. 2 exemplarily shows the package structure in a closed position.

In the first open position, the angle between the cover 200 and the base 100 is greater than 0 °. For example: the included angle between the base 100 and the cover 200 is any one value or any two values of 40 °, 45 °, 60 °, 70 °, 90 °, 120 ° or 180 °. When the included angle between the cover 200 and the base 100 is large, the first open position may be a desired open position, and at this time, the user can take the object. Fig. 8 exemplarily shows the package structure in a first open position.

Without limitation, as shown in fig. 4, the cantilever 120 and the base 110 are of a unitary structure, for example, the cantilever 120 and the base 110 may be integrally formed by molding or machining. As shown in fig. 3, the protrusion portion 220 and the main body portion 210 are of a unitary structure, for example, the protrusion portion 220 and the main body portion 210 may be integrally formed by molding or machining. When the protrusion 220 and the base 110 rotate relatively, the main body 210 and the base 110 are driven to rotate relatively, and meanwhile, an acting force is applied to the cantilever 120, so that the cantilever 120 deforms and stores an elastic restoring force.

The cantilever 120 includes: a first transition portion 121, and a first surface 122 and a second surface 123 respectively located at both sides of the first transition portion 121; when the main body portion 210 is at the transition position, the protrusion portion 220 contacts the first transition portion 121, so that the cantilever 120 is in a deformed state storing a first elastic restoring force; when the body portion 210 is located between the closed position and the transitional position, the protrusion 220 engages the first surface 122 to place the cantilever 120 in a deformed state storing a second elastic restoring force; when the body portion 210 is between the transition position and the first open position, the protrusion 220 engages the second surface 123 to place the cantilever 120 in a deformed state storing a third elastic restoring force; wherein the first elastic restoring force is greater than the second elastic restoring force and the third elastic restoring force, respectively.

As shown in FIG. 4, first transition 121, first surface 122, and second surface 123 are all part of the outer surface of cantilever 120. The first transition portion 121 is located at the intersection of the first surface 122 and the second surface 123, and is connected to the first surface 122 and the second surface 123, respectively. During the movement of the main body portion 210 from the closed position to the first knock position, the protrusion 220 is in sliding contact with the first surface 122, the first transition portion 121, and the second surface 123 in sequence. During the movement of the main body portion 210 from the first knock position to the closed position, the protrusion 220 is sequentially in sliding contact with the second surface 123, the first transition portion 121, and the first surface 122.

In order to ensure the smoothness of the protrusion 220 moving along the surface of the cantilever 120, the first surface 122 and the second surface 123 smoothly transition to two sides of the first transition portion 121.

In the transition position, the deformation of the cantilever 120 is the largest, and the first elastic restoring force value stored in the cantilever 120 is the largest.

Alternatively, the first transition portion 121 may be in point, line, or surface contact with the protrusion 220 when in the transition position.

As shown in fig. 7 and 9, the arc-shaped arrows in fig. 7 and 9 are directed in the rotational direction of the cover body 200. Fig. 7 shows the cover 200 being rotated from the closed position to the first open position. Similarly, as shown in fig. 9, the cover 200 is shown being rotated from the first open position to the closed position. It follows that the transition position is passed whether the closed position is shifted to the first open position or the first open position is shifted to the closed position. The cantilever arms 120 provide resistance to both the movement of the cover body 200 from the first open position to the closed position and the movement from the closed position to the first open position by the elastic restoring force generated by the cooperation with the protrusions 220. In practical applications, a large external force is required to overcome the resistance. This resistance enables not only the main body 210 to be maintained in the closed position, but also the main body 210 to be maintained in the first open position.

The second elastic restoring force and the third elastic restoring force are both smaller than the first elastic restoring force, so that once the transition position is crossed in the relative rotation process of the cover body 200 and the base body 100, the main body 210 is automatically restored from the transition position to the first open position or from the transition position to the closed position by the protrusion 220 under the action of the first elastic restoring force of the cantilever 120. The automatic closing and opening process improves the use experience of the user.

As shown in fig. 5 to 9, the protrusion 220 rotates relative to the base 110 and contacts the cantilever 120 to limit the opening or closing of the body 210. Compared to the solution of fig. 1 that requires the locking member 40 to lock the cover 10 on the base 20 in the closed position, the solution of the embodiment of the present invention does not require an additional locking member at the position of the locking member in fig. 1, that is, at the position of the seat 100 away from the protrusion 220. The appearance simplicity and cleanliness of the packaging structure are improved, and the use feeling of a user is further improved.

In other alternative embodiments, when the main body portion 210 is in the closed position, the cantilever 120 is in a deformed state storing a fourth elastic restoring force, wherein the fourth elastic restoring force is smaller than the first elastic restoring force.

As shown in fig. 5, in the closed position, the elastic restoring force (indicated by arrow F in fig. 5) stored in the cantilever 120 can limit the rotation of the cover 200 relative to the base 100, so that the cover 200 cannot be moved to the first open position, and at this time, the reliability of the closure in the closed position can be further improved, and the situation of opening the packaging structure due to accident can be reduced, thereby effectively reducing the spilling of the target object.

As shown in fig. 8, in the first open position, the protruding portion 220 may be in only abutting state with the cantilever 120, but the cantilever 120 is not deformed, and the cover 200 is maintained in the first open position by the support of the cantilever 120 unless the elastic restoring force generated by the cantilever 120 can be overcome. At this time, the packaging structure also reduces the phenomenon that the cover 200 is closed relative to the seat 100 due to accidents such as collision, and further improves the user experience.

In other optional embodiments, the cantilever 120 further comprises a fixed end 124 and a free end 125, wherein the free end 125 is an opposite end of the fixed end 124, the fixed end 124 is connected to the base 110, and the first transition portion 121 is located between the fixed end 124 and the free end 125.

As shown in fig. 4, the first transition portion 121, the first surface 122, and the second surface 123 are closer to the free end 125 of the cantilever 120 than the fixed end 124. When the protruding portion 220 abuts against the first transition portion 121, the first surface 122 and the second surface 123 closer to the free end 125, a larger elastic restoring force of the cantilever 120 can be obtained by a smaller external force, so as to further improve the smoothness when the cover 200 is closed or opened relative to the seat 100.

Without limitation, the cantilever 120 is a generally plate-like structure. First surface 122, first transition 121, and second surface 123 collectively form a convex portion attached at free end 125, the convex portion projecting in a direction toward boss 220.

The first surface 122 extends obliquely from the free end 125 of the cantilever 120 to the first transition 121 in a direction toward the boss 220; the second surface 123 extends obliquely from the first transition portion 121 toward the fixed end 124 of the cantilever 120 in a direction away from the protrusion 220.

As shown in FIG. 6, the cantilever 120 stores a second elastic restoring force value between the fourth elastic restoring force value and the first elastic restoring force value during the movement of the protrusion 220 along the first surface 122 toward the first transition portion 121, and gradually increases. During the movement of the protrusion 220 away from the first transition portion 121 along the second surface 123, the third elastic restoring force stored in the cantilever 120 is smaller than the first elastic restoring force and gradually decreases.

In other alternative embodiments, the body portion 210 further has a second open position relative to the base 110, and the angle between the body portion 210 and the base 110 in the second open position is greater than the angle between the body portion 210 and the base 110 in the first open position.

Fig. 8 exemplarily shows a state of the packaging structure in the first open position. If the first open position is not the ideal open position, it is inconvenient for the user to access the object. It is also possible to continue to rotate the cover body 200 in the same direction as the closed position toward the first open position, i.e., to continue to rotate as indicated by the arrow in fig. 8, so that the body portion 210 is opened at a greater angle with respect to the base 110.

Without limitation, the cantilever 120 may not be elastically deformed and not store an elastic restoring force between the first open position and the second open position.

In other alternative embodiments, the base 110 includes: a limiting surface 1141, wherein the limiting surface 1141 is connected to the fixed end 124 of the cantilever 120; when the main body 210 is in the second open position, the protruding portion 220 abuts against the limiting surface 1141.

As shown in fig. 4-9, the stop surface 1141 may be a portion of the surface of the base 110. When the body portion 210 is in the first open position, the protruding portion 220 is located between the second surface 123 and the position-limiting surface 1141, and is spaced apart from the position-limiting surface 1141.

The limiting surface 1141 limits the maximum angle at which the main body 210 can be opened relative to the base 110, that is, when the main body 210 is at the second opening position, the protruding portion 220 is limited by the limiting surface 1141, and the protruding portion 220 cannot continue to drive the main body 210 to rotate.

In other optional embodiments, the packaging structure further comprises: an elastic member 400 attached to the base 110 and abutting against the arm 120; the elastic member 400 is configured to provide an elastic restoring force to the cantilever 120 toward the boss 220.

As shown in fig. 5 and 8, the protrusion 220 and the elastic member 400 are respectively located at opposite sides of the cantilever 120. While the protruding portion 220 compresses the cantilever 120 to deform, the cantilever 120 also compresses the elastic member 400 to deform, and the elastic member 400 stores an elastic restoring force, and the elastic restoring force stored by the elastic member 400 has the same direction as the elastic restoring force stored by the cantilever 120.

The elastic member 400 is used to further increase the elasticity of the cantilever 120, and has a supporting effect on the cantilever 120, so as to enhance the elasticity of the cantilever 120 and reduce the risk of breakage of the cantilever 120 due to deformation.

The elastic member 400 may be made of a material having elasticity, such as rubber, without limitation.

In other alternative embodiments, the base 110 includes: a bottom plate 111, side walls 112, and blocking walls 113; wherein, the side wall 112 is arranged at the edge of the bottom plate 111; the cantilever 120 is connected to the sidewall 112; the blocking wall 113 is connected with the bottom plate 111, is positioned between the central position of the bottom plate 111 and the cantilever 120, and forms an accommodating cavity 130 together with the cantilever 120; the receiving chamber 130 receives the elastic member 400.

As shown in fig. 4, the bottom plate 111 and the side wall 112 together define a receiving chamber 115 for receiving an object.

The blocking wall 113 and the cantilever 120 together form a cavity wall of the accommodating cavity 130, and the elastic element 400 is located in the accommodating cavity 130 and contacts with the cantilever 120. The accommodating cavity 130 is not only beneficial to reducing the corrosion of the elastic member 400 caused by the outside liquid or dust, but also can reduce the possibility that the elastic member 400 contacts with the target object in the accommodating cavity 115.

In other alternative embodiments, the sidewall 112 has a notch 140; the base 110 further comprises a cross beam 114, the cross beam 114 is located in the gap 140, and two ends of the cross beam 114 are respectively connected with the side walls 112; the cantilever 120 is connected between the two ends of the beam 114; when the body portion 210 is in the closed position, at least a portion of the protrusion 220 is located between the first surface 122 and the bottom plate 111.

As shown in fig. 4, 5 and 8, the blocking wall 113 is located in the accommodating cavity 115, and the accommodating cavity 130 defined by the blocking wall 113 and the cantilever 120 is located in the accommodating cavity 115.

The cantilever 120 is connected between the two ends of the beam 114 and is located in the notch 140 of the sidewall 112, so that when the cantilever 120 is deformed under compression, the sidewall 112 does not contact the cantilever 120, and the interference of the sidewall 112 on the deformation of the cantilever 120 is reduced.

The free end 125 of the cantilever arm 120 is spaced from the base 111 and the projection 220 is positioned in the space between the free end 125 of the cantilever arm 120 and the base 111 in the closed position.

In other alternative embodiments, the boss 220 includes: a second transition portion 221, and a third surface 222 and a fourth surface 223 respectively located at both sides of the second transition portion 221.

As shown in fig. 2, the second transition portion 221, the third surface 222, and the fourth surface 223 are all part of the outer surface of the boss 220. The second transition portion 221 is located at the intersection of the third surface 222 and the fourth surface 223, and is connected to the third surface 222 and the fourth surface 223, respectively.

Without limitation, boss 220 also has a free end 224, and third surface 222, second transition 221, and fourth surface 223 collectively form a convex portion attached to free end 224 of boss 220, the convex portion projecting in a direction toward cantilever 120.

When the body portion 210 is in the closed position, the third surface 222 is in contact with the first surface 122; when the body portion 210 is in the first open position, the fourth surface 223 is in contact with the second surface 123; when the main body portion 210 is in the transition position, the second transition portion 221 is in contact with the first transition portion 121.

In other optional embodiments, the packaging structure further comprises: and anti-slip lines are arranged on the cantilever 120 and/or the convex part 220.

The anti-slip pattern is beneficial to increasing the friction force in the process of jointing the convex part 220 and the cantilever 120, improving the damping force, leading the sliding to be slowly carried out and improving the controllability of the rotating speed in the automatic rotating process.

In practical applications, the anti-slip texture may be provided on at least one of the first surface 122, the first transition portion 121, the second surface 123, the third surface 222, the second transition portion 221, or the fourth surface 223.

Without limitation, the anti-skid texture includes: raised or depressed dots, lines or other patterned lines.

In other optional embodiments, the packaging structure further comprises: a rotating shaft 500, wherein the rotating shaft 500 is respectively connected with the protruding part 220 and the base 110; the protrusion 220 rotates relative to the base 110 via the rotation shaft 500.

As shown in fig. 6 and 7. The boss 220 has a first mounting hole 225, and the base 110 has a second mounting hole 126. The shaft 500 is inserted into the first mounting hole 225 and the second mounting hole 126, and the protrusion 220 and the base 110 are rotatable relative to the axis of the shaft 500.

As shown in fig. 5 to 9, the protrusion 220 is used for mounting the rotating shaft 500 in addition to applying a force to the cantilever 120 to drive the cantilever 120 to deform, so that the space of the protrusion 220 is more fully utilized, and the compactness and the tidiness of the appearance of the packaging structure are further improved.

It is understood that the packaging structure can also adopt other structures such as gears to realize the rotation of the protruding portion 220 relative to the base 110 besides the rotating shaft 500.
