Furthermore, the lid body also includes an elastic element fixed to the lid body, and the button is engaged with the lid body by means of the elastic element.

[0011] According to another aspect of this disclosure, the elastic element includes an axially extending spring, wherein one end of the spring is fixed to a panel snapped onto the cover body, and the other end is embedded in the button from the lower surface of the lower portion of the button.

[0012] According to another aspect of this disclosure, the elastic element biases the lower part of the button to abut against the top wall of the cover body.

[0013] According to another aspect of this disclosure, the lower part of the button includes two latches, wherein the panel is located between the two latches.

[0014] According to another aspect of this disclosure, the opening radially penetrates the top wall of the cover body, wherein two secondary openings extending axially from both ends of the opening are formed on the peripheral wall of the cover body, and wherein the length of each of the secondary openings is not less than the axial distance from the lower surface of the lower part of the button to the panel when the lower part of the button abuts against the top wall of the cover body.

[0065] The following description of specific embodiments of this utility model refers to the accompanying drawings, which illustrate particular embodiments in which the utility model can be practiced. The embodiments are intended to describe various aspects of the utility model in sufficient detail to enable those skilled in the art to practice it. Other embodiments and changes may be utilized without departing from the scope of the utility model. Therefore, the following description of specific embodiments should not be considered limiting. The scope of this utility model is defined only by the appended claims and the full scope of their equivalents. The same reference numerals are used throughout the drawings and specific embodiments to refer to the same or similar parts.

[0066] As shown in the attached figures, the packaging structure 100 of the preferred embodiment of this utility model is generally a cylindrical rotating component that rotates around a rotation axis A. The axial direction X is parallel to the rotation axis A, while the radial direction Y is perpendicular to the rotation axis A. Directions X and Y are perpendicular to each other, and the circumferential direction is the direction of rotation around the rotation axis A. Terms such as "inner" and "outer" are defined relative to the external environment of the packaging structure 100 itself. For example, components located further inside the packaging structure 100 are closer to the rotation axis A than components located further outside the packaging structure 100. Positional terms such as "upper," "lower," "top," and "bottom" refer to the packaging structure 100 in its working position (e.g., ...). Figures 2 to 4 The relative orientation term in relation to the placement and position shown.

[0067] Figure 1 An exploded perspective view of a preferred embodiment of the packaging structure 100 is shown, while Figures 2 to 4 A cross-sectional view of the packaging structure 100 in the XY plane is shown.

[0068] like Figure 1 As shown, the packaging structure 100 generally includes a can body 1 with a joint 3 and a lid 4. The lid 4 can be connected to the joint 3 and is therefore movable between a snap-fit ​​state, a pre-disengaged state, and a disengaged state. Figure 2 This shows that cover 4 is in the detached state. Figure 3 This shows that the cover 4 is in a latched state, while Figure 4 This shows that cover 4 is in a pre-detached state.

[0069] The tank body 1 includes a tank body 2 and a connecting portion 3. The tank body 2 is a hollow container, while the connecting portion 3 is located above the tank body 2 and is in fluid communication with the tank body 2. Preferably, the connecting portion 3 is generally cylindrical. The connecting portion 3 includes, from top to bottom, a connecting flange 34 and a connecting neck 31. The connecting neck 31 is connected to the connecting flange 34 at its first end 32 and to the tank body 2 at its second end 33 opposite to the first end 32. The connecting flange 34 extends radially outward from the first end 32 of the connecting neck 31. Preferably, the connecting portion 3 is integrally formed with the tank body 2.

[0070] Furthermore, the joint 3 also includes a collar 37. The collar 37 is fitted onto the joint neck 31, and its inner diameter is slightly larger than the outer diameter of the joint neck 31, allowing the collar 37 to slide between the first end 32 and the second end 33 of the joint neck 31. The collar 37 can abut against the joint flange 34 at the first end 32 of the joint neck 31 and against the can body 2 at the second end 33 of the joint neck 31. Preferably, the outer diameter d2 of the collar 37 gradually decreases from the first end 32 to the second end 33 of the joint neck 31, that is, the outward-facing outer surface 38 of the collar 37 is inclined inward.

[0071] like Figure 1 As shown, the cover 4 includes a cover body 5 and a button 6. The cover body 5 includes a radially extending top wall 51 and a peripheral wall 52 extending axially downward around the top wall 51. Figures 2 to 4 As shown, the peripheral wall 52 abuts against the can body 2 at its lower end, i.e., the end furthest from the top wall 51. Preferably, the outer diameter of the lid body 5 is equal to the outer diameter of the can body 2, so that the packaging structure 100 generally presents a cylindrical shape, enhancing its aesthetic value.

[0072] Still Figure 1 As shown, the cover body 5 has an opening 53 on its top wall 51, which radially penetrates the 51 of the cover body 5, and two opposing secondary openings 54a and 54b are opened on the peripheral wall 52 at both ends along the axial direction Y.

[0073] The cover 4 of the packaging structure 100 also includes a button 6. The button 6 is mounted in an opening 53 of the cover body 5. Specifically, the button 6 has an upper portion 7 and a lower portion 8. The upper portion 7 is exposed outside the cover body 5 via the opening 53 and protrudes upward relative to the top wall 51 of the cover body 5; while the lower portion 8 is located inside the cover body 5 and includes a plurality of axially extending claws 9. In this preferred embodiment, the lower portion 8 includes two claws 9.

[0074] The upper part 7 of button 6 has a radially extending radial arm 71 and two axial arms 72a and 72b extending axially downward from both ends of the radial arm 71. The extending direction of the radial arm 71 is the same as the extending direction of the opening 53 of the cover body 5, and preferably, their dimensions are matched so that when button 6 is pressed down, the radial arm 71 of its upper part 7 can precisely fill the opening 53. It is conceivable that when the cover body 4 is in the snap-fit ​​state, the radial arm 71 is flush with the top wall 51 of the cover body 5, forming a single plane. The axial arms 72a and 72b correspond to the secondary openings 54a and 54b, respectively, and cover the secondary openings 54a and 54b on the outer side of the peripheral wall 52 of the cover body 5. The secondary openings 54a and 54b are provided to allow the radial arm 71 of the upper part 7 of button 6 to move axially relative to the cover body 5.

[0075] The lower portion 8 of button 6 is connected to the upper portion 7 and is always located inside the cover body 5. Specifically, the lower portion 8 is sized so that its upper surface 81 abuts against the top wall 51 of the cover body 5 across the opening 53 to prevent the lower portion 8 from moving upward away from the cover body 5. The cover body 5 also includes an elastic member 55 and a panel 56. The panel 56 extends radially, while the elastic member 55 extends axially, connecting the lower portion 8 of button 6 and the panel 56. In this preferred embodiment, the elastic member 55 includes a spring, one end of which is fixed to the panel 56, and the other end of which is embedded in the button 6 from the lower surface 82 of the lower portion 8. Thus, the elastic member 55 biases the lower portion 8 of button 6 abutting against the top wall 51 of the cover body 5, such that the upper portion 7 of button 6 protrudes upward through the opening 53 from the cover body 5.

[0076] like Figure 5 As shown, a snap-fit ​​portion 10 is also provided, which includes a flange 11 at its bottom. The snap-fit ​​portion 10 includes two symmetrical parts with respect to the axis of rotation A, and a panel 56 is sandwiched between these two parts. Preferably, the panel 56 is integral with the snap-fit ​​portion 10; in alternative embodiments, it is also conceivable to snap the panel 56 between the two parts of the snap-fit ​​portion 10. The snap-fit ​​portion 10 can be inserted into the cover body 5 from bottom to top until its flange 11 abuts against the peripheral wall 52 of the cover body 5 from the bottom of the cover body 5. Preferably, the flange 11 is sized to be flush with the peripheral wall 52 of the cover body 5 to increase the aesthetic effect of the packaging structure 100 and prevent accidental snagging. The snap-fit ​​portion 10 can be secured to the cover body 5 using any suitable fastening means such as adhesive or snap-fit.

[0077] The exemplary steps for assembling the cover 4 are as follows:

[0078] Insert button 6 into the cover body 5 from the bottom of the cover body 5, and adjust the position so that the upper part 7 of button 6 passes through the opening 53 and is outside the cover body 5, while the lower part 8 of button 6 abuts against the cover body 5 from the inside of the cover body 5.

[0079] Place the elastic element 55 from the bottom of the cover body 5 into the cover body 5 until it abuts against the lower surface 82 of the lower part 8 of the button 6.

[0080] Insert the snap-fit ​​part 10 with the panel 56 installed into the cover body 5 from the bottom until the panel 56 contacts the elastic member 55 and the flange 11 of the snap-fit ​​part 10 abuts against the peripheral wall 52 of the cover body 5.

[0081] Secure the buckle part 10 to the cover body 5.

[0082] Preferably, the radial arm 71 of the upper part 7 of the button 6 extends across the upper surface 81 of the lower part 8 of the button 6, such that the axial arms 72a and 72b of the upper part 7 correspond to the two claws 9 of the lower part 8, respectively. In this way, a force can be applied to the upper part 7 of the button 6, so that the button 6 moves in the axial direction Y, thereby changing the engagement relationship between the claws 9 and the joint 3 of the can body 1, so that the cover 4 moves between the latched state, the pre-disengaged state, and the disengaged state.

[0083] Therefore, in order not to hinder the axial movement of button 6, the axial length l3 of each of the secondary openings 54a and 54b of the cover body 5 is not less than the axial distance l4 from the lower surface 82 of button 6 to the panel 56 of cover body 5 when the lower part 8 of button 6 abuts against the top wall 51 of cover body 5 due to the action of elastic member 55.

[0084] In this preferred embodiment, the claw 9 is shaped such that its circumferential curvature matches the joint portion 3 of the can body 1, allowing it to make tight contact with the engagement flange 34 of the joint portion 3. The panel 56 of the cover body 5 is positioned between the two claws 9 to avoid obstructing the axial movement of the claws 9. Figures 2 to 4 As shown, the claw 9 has an inclined surface 91 and an upper surface 92 that are adjacent to each other. When the cover 4 is in the position as shown... Figure 2 In the disengaged state shown, the pawl 9 can contact the engagement flange 34 but not the collar 37. Specifically, the pawl 9 can contact the engagement flange 34 with its inclined surface 91. Therefore, the engagement flange 34 can be provided with a ramp surface 35, the inclination of which is complementary to the inclination of the inclined surface 91 of the pawl 9, to allow them to fit together and increase the contact area between the pawl 9 and the engagement flange 34. In this preferred embodiment, the outer diameter d1 of the engagement flange 34 gradually increases along the direction from the first end 32 to the second end 33 of the engagement neck 31, that is, the ramp surface 35 of the engagement flange 34 is inclined outward. However, the present invention is not limited to this, and the engagement flange 34 may also not be provided with a ramp surface 35, and its outer diameter d1 remains constant.

[0085] When the claw 9 is like Figure 3When the upper surface 92 of the cover 4 abuts against the bottom surface 36 of the engagement flange 34, the cover 4 enters a snap-fit ​​state and engages with the can 1. Due to the compression of the elastic element 55, it tends to bias the button 6 upward back to the state where its lower part 8 abuts against the top wall 51 of the cover body 5, thereby making the claw 9 firmly abut against the engagement flange 34 upward. Without external force, the cover 4 and the can 1 will not disengage.

[0086] Therefore, in order to allow changes in the engagement state between the clasp 9 and the engagement flange 34, the collar 37 is sized such that its axial length l1 is less than the distance l2 from the first end 32 to the second end 33 of the engagement neck 31, and its axial length l1 allows the clasp 9 of the cover 4 to... Figure 4 The outer surface 38 of both the tank body 2 and the collar 37 is shown. Preferably, as... Figure 4 As shown, the maximum outer diameter d2 of the collar 37 is not less than the maximum outer diameter d1 of the engagement flange 34. In this way, it can be ensured that the tip of the pawl will not abut against the bottom surface 36 of the engagement flange 34 again after sliding upward over the outer surface 38 of the collar 37.

[0087] When it is necessary to fasten the lid 4 to the can 1 to prevent the contents of the can 1 from contacting the outside, a downward force is applied to the button 6. The elastic element 55 is compressed, and the claw 9 moves downward to contact the engaging flange 34, thus being pushed outward by the engaging flange 34 until the tip of the claw 9 completely slides over the ramp surface 35 of the engaging flange 34. Due to its own elasticity, the claw 9 rebounds inward, and its upper surface 92 contacts the bottom surface 36 of the engaging flange 34. At this time, the downward force is withdrawn, and the restoring force of the elastic element 55 holds the claw 9 firmly against the engaging flange 34. The lid 4 is as follows... Figure 3 As shown, it enters the snap-fit ​​state and engages with the can body 1. The inclined surface 91 of the claw 9 can abut against the collar 37 to push the collar 37 into place, increasing the overall stability of the packaging structure 100; but it can also not abut against the collar 37, allowing it to retain a certain amount of free movement.

[0088] When it is necessary to open cover 4, such as Figure 3 As indicated by the hollow arrow, a downward force is applied to button 6, causing the inclined surface 91 of the pawl 9 to move downward, bringing the pawl 9 into contact with the collar 37 and pushing it outward by the collar 37. When the pawl 9 moves to the point where its tip contacts the outer surface 38 of the collar 37, due to the inward inclination of the outer surface 38, the force exerted by the pawl 9 on the collar 37 has an upward component, causing the collar 37 to move upward until it abuts against the engaging flange 34. At this time, the cover 4... Figure 4 As shown, in the pre-disengagement state, the collar 37 abuts against the pawl 9 and pushes the pawl 9 outward. When the downward force is released, the pawl 9 will move upward due to the restoring force of the elastic element 55, sliding successively over the collar 37 and the engagement flange 34, returning to its original position. Figure 2The disengaged state is shown, where the engagement with the engagement flange 34 is terminated. In the disengaged state, the pawl 9 is not in contact with the collar 37, and the user can lift the lid 4 away from the can body 1 by holding the upper part 7 of the button 6.

[0089] The packaging structure of this utility model adopts a snap-fit ​​mechanism mainly composed of a claw mounted on the button, a connecting flange, and a collar to complete the snap-fit ​​engagement and disengagement operations. The lid is engaged and disengaged by pressing the button, allowing the operator to easily open and close the lid of the packaging structure with less force, shorter force application time, and a smaller contact area with the packaging structure. This avoids affecting the opening and closing of the lid when the operator's hands are dirty, thus solving the problem of poor usability of the packaging structure in the prior art.

For example, a method, article, or apparatus that includes a list of elements is not necessarily limited to those elements and may also include other elements not expressly listed or inherent to the method, article, or apparatus.

[0091] This utility model is not limited to the above embodiments, which are merely illustrative and not restrictive. Those skilled in the art, under the guidance of this utility model, can make any possible changes and modifications without departing from the spirit and scope of the claims. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model, without departing from its scope of protection, fall within the scope defined by the claims.
