[0032] Example:
[0033] See also Figures 1 to 10 , a packaging container 10, the packaging container 10 is made of elastic material;
[0034] The packaging container 10 includes an integrally formed bottle body 100 and a bottle bottom 200. The bottle body 100 has at least one foldable structure 110. The length of the foldable structure 110 extends perpendicular to the bottle bottom 200.
[0035] The bottle bottom 200 is provided with a guide groove 210 , the width of which gradually expands from the top to the bottom groove. The guide groove 210 extends toward both ends of the foldable structure 110 to the bottle body 100 to form a side groove 120 .
[0036] When the packaging container 10 is not filled with contents, pressure is applied to the bottle body 100. Since the bottle body 100 is elastic and has a foldable structure 110 arranged on the side, the bottle body 100 can be folded along the extension trajectory of the foldable structure 110. Since the foldable structure 110 at least partially extends to the side groove 120, the side groove 120 and the connected guide groove 210 can also be compressed to a certain extent, thereby reducing the volume of the packaging container 10 and facilitating carrying and transportation.
[0037] When pressure is removed from the bottle body 100 and the packaging container 10 is filled, the bottle body 100 can return to its maximum volume due to its elasticity. The contraction structure of the guide groove 210 provides a certain structural strength to the bottle bottom 200, allowing the packaging container 10 to be stably placed on a flat surface.
[0038] It should be noted that in the present application, the packaging container is a bottle-shaped container, the height direction of the bottle body is parallel to the axial direction, the width direction and thickness direction of the bottle body are both perpendicular to the axial direction, and there is an angle between the width direction and the thickness direction of the bottle body. In a preferred embodiment, the width of the bottle body is greater than the thickness. In other embodiments, there is no restriction on the width and thickness of the bottle body.
[0039] It should also be noted that in some embodiments, there may be multiple or only one easily foldable structures, the number of easily foldable structures may be an even number or an odd number, and the length extension direction of the easily foldable structure may be parallel to the height direction of the bottle body or may be at an angle to the height direction of the bottle body.
[0040] Furthermore, the packaging container 10 is preferably made of plastic.
[0041] Furthermore, the bottle body 100 has 2N easily breakable structures 110 , where N is a positive integer and N≥1; the width direction of the bottle body 100 is perpendicular to the axis of the bottle body 100 , and the easily breakable structures 110 are arranged opposite to each other in the width direction of the bottle body 100 .
[0042] The packaging container 10 in the related art is often folded along the height direction of the bottle body 100, and the volume is reduced by compressing the height of the packaging container 10. The packaging container 10 of this design has a complex structure and usually adopts a multi-pleat design. The production cost and process complexity are relatively high, and most packaging containers 10 can only be folded once and cannot be reused.
[0043] like Figure 2 As shown, the packaging container 10 in this embodiment is foldable along the width of the bottle body 100. This design not only offers excellent foldability, but also allows the bottle body 100, bottle base 200, and bottle neck 300 to be integrally formed, ensuring uniform wall thickness across all parts of the packaging container 10. The multi-stage, contracting design of the guide grooves 210 in the bottle base 200 enhances the structural strength and support stability of the packaging container 10. This ensures sufficient structural strength even with thinner bottle walls, saving manufacturing materials and reducing production costs.
[0044] Further, if Figure 2 and 3 As shown, the thickness direction of the bottle body 100 is perpendicular to the axis of the bottle body 100 , the width of the bottle body 100 is greater than the thickness, and the easily breakable structures 110 are relatively arranged along the width direction of the bottle body 100 .
[0045] As can be appreciated, the flat shape of the bottle body 100, whether filled or not, allows for more efficient use of storage space, reducing the volume occupied during transportation and storage, saving transportation costs and storage space. The flat shape of the bottle body 100 also facilitates squeezing the bottle body 100, making folding the bottle body 100 along the extended path of the foldable structure 110 more labor-saving.
[0046] Further, if Figure 4 and 5 As shown, the easily breakable structure 110 is a protrusion protruding outward on the bottle body 100; along a direction parallel to the bottle bottom 200, the curvature α of the cross section of the protrusion is 90° to 120°.
[0047] In this embodiment, the wall thickness of the bottle body 100 and the bottle base 200 of the packaging container 10 is equal at all locations. The easily foldable structure 110 achieves foldability of the packaging container 10 not by thickening or thinning the bottle body 100, but rather by designing a protrusion with a thickness equal to the wall thickness of the bottle body 100. The protrusion provides additional support and structural strength at the folding point of the bottle body 100. Especially in situations where the bottle body 100 is frequently folded or subjected to pressure, the protrusion can reduce material fatigue and the risk of breakage near the fold line of the bottle body 100. When the bottle body 100 is folded along the extension path of the easily foldable structure 110, the protrusion ensures that the bottle body 100 near the fold line is not excessively squeezed, thereby maintaining the shape and structural integrity of the folded bottle body 100.
[0048] Preferably, the projection width of the protrusion along the width direction of the bottle body is 1 mm to 5 mm. When the protrusion is set to this width, it can play a role in guiding folding, and the foldability of the packaging container 10 is optimal.
[0049] In other embodiments, the easily foldable structure 110 is not limited to being a protrusion protruding outward on the bottle body 100 . The easily foldable structure 110 may also be a groove recessed inward on the bottle body 100 .
[0050] Furthermore, a portion of the easily foldable structure 110 is a protrusion protruding outward on the bottle body 100 , and another portion of the easily foldable structure 110 is a groove recessed inward on the bottle body 100 .
[0051] In some embodiments, as Figure 9 As shown, the packaging container 10 is provided with a pair of easily foldable structures 110, such as Figure 9 As shown, the arrows indicate the direction of movement of the bottle body 100 surface on either side of each easily-breakable structure 110 when the packaging container 10 is reduced in volume. The easily-breakable structure 110 is a protrusion on the bottle body 100 that protrudes outward. Along a direction parallel to the bottle base 200, the cross-section of the bottle body 100 is formed by a combination of multiple arcs that bend outward from the packaging container 10.
[0052] In other embodiments, the packaging container 10 is provided with multiple pairs of easy-folding structures 110, such as Figure 10 As shown, the convex foldable structure 110 protruding outward on the bottle body 100 is a convex foldable structure 110, and the concave foldable structure 110 concave inward on the bottle body 100 is a concave foldable structure 110. The packaging container 10 can be provided with 2N convex foldable structures 110 and 2N-1 concave foldable structures 110, N is a positive integer and N≥1, and a concave foldable structure 110 is provided between every two adjacent convex foldable structures 110.
[0053] like Figure 10As shown, the arrows indicate the movement direction of the bottle body 100 surface on both sides of each easy-folding structure 110 when the volume of the packaging container 10 is reduced. Such a setting can make the folded and compressed volume of the packaging container 10 change more greatly, but it is easier to rebound than the packaging container 10 using only a pair of easy-folding structures 110.
[0054] The cross section of the bottle body 100 can be formed by a combination of multiple arcs that are curved outward and inward toward the packaging container 10. In other embodiments, along a direction parallel to the bottle bottom 200, the cross section of the bottle body 100 can also be an ellipse or other curved shape.
[0055] In some embodiments, as Figure 6 and 7 As shown, along the direction parallel to the bottle bottom 200 , the cross section of the bottle body 100 is formed by combining multiple arc segments.
[0056] The cross section of the guide groove 210 is parallel to the extension direction of the breakable structure 110. The cross section of the guide groove 210 comprises three sequentially connected sections from the opening to the top. The slope of the first section 210a of the guide groove 210 gradually increases to the first slope. The slope of the second section 210b of the guide groove 210 is the first slope. The slope of the third section 210c of the guide groove 210 gradually decreases from the first slope. Compared to a guide groove 210 with a constant cross-sectional slope, this arrangement provides greater support strength for the guide groove 210.
[0057] In other embodiments, the cross section of the guide groove 210 may also be arc-shaped, V-shaped, or U-shaped.
[0058] Further, if Figure 8 As shown, the side groove 120 gradually increases in depth from the bottle body 100 to the bottle bottom 200 .
[0059] On the one hand, the design of the side grooves 120 enhances the bottle's support stability. The guide grooves 210 at the bottle base 200 and the side grooves 120 near the bottle base 200 both have good structural strength when uncompressed. Therefore, further design is required to facilitate folding of the side grooves 120 or the guide grooves 210. The gradually increasing depth of the side grooves 120 facilitates the folding of the guide grooves 210. Furthermore, the curved design evenly distributes stress during folding, reducing damage to the bottle body 100 during the folding process. The curved transition prevents damage or deformation to the bottle body 100 that could result from right-angle folding.
[0060] Preferably, Figure 1 As shown, the breakable structure 110 at least partially extends into the side groove 120 .
[0061] Preferably, Figure 2 and 3 As shown, the packaging container 10 further includes a bottleneck 300 that contracts from the bottle body 100 toward away from the bottle bottom 200 , and the easily breakable structure 110 at least partially extends to the bottleneck 300 .
[0062] The bottleneck 300 of the packaging container 10 can also be folded along the extension track of the easy-folding structure 110 , so that the volume of the packaging container 10 can be further reduced.
[0063] Further, if Figure 1 As shown, the bottle neck 300 is provided with an external thread 310 , and the bottle neck 300 is used for sealing connection with the cover body.
[0064] In this embodiment, the cover body can be sealed and connected to the bottleneck 300, applying pressure to the bottle body 100, and the bottle body 100 folds along the extension trajectory of the foldable structure 110. The air inside the packaging container 10 is squeezed out and the packaging container 10 is compressed. At this time, the bottleneck 300 is sealed and connected through the cover body. Since the air pressure inside the packaging container 10 is lower than the external air pressure, the packaging container 10 will not return to its original state, so that the packaging container 10 can further maintain the compressed state, which increases the convenience of the packaging container 10 and can effectively reduce transportation costs.
[0065] Preferably, Figure 6 As shown, there is a smooth transition surface between the bottle body 100 and the bottle bottom 200, the packaging container is not easy to wear, the durability of the bottle bottom 200 during transportation is enhanced, the risk of damage to the bottle bottom 200 of the packaging container 10 during transportation is effectively reduced, and good support stability is provided.
[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
