Description

Bottle cap and bottle having the same Technical Field

[0001] The present disclosure relates to the field of washing product packaging, and more particularly, to a bottle cap and a bottle having the bottle cap. Background Art

[0002] The background description provided herein is intended to generally present the context of the present disclosure. To the extent described in this background section, the work of the presently named inventors and aspects of the description that may not constitute prior art at the time of filing are neither explicitly nor implicitly admitted to be prior art with respect to the present disclosure.

[0003] Daily laundry products are typically large and heavy, and are frequently transported, which can lead to leaks due to drops during transportation. Compared to lighter products, leak prevention within the supply chain is particularly challenging.

[0034] Hereinafter, the present disclosure will be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the present disclosure are shown. However, the present disclosure can be implemented in different embodiments and should not be construed as being limited to the embodiments described herein. These embodiments provided by the present disclosure are intended to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art. In the accompanying drawings, the thickness and area of ​​the layers may be magnified for clarity. Throughout the specification, the same reference numerals are used to represent the same elements. For different embodiments, the elements may have different relationships and different positions.

[0035] The present application proposes a bottle cap for a bottle containing liquid. By improving the bottle cap itself and the connection between the bottle cap and the bottle, especially increasing the length of the support ring and the bottle cap wall, the leakage problem of heavy products is effectively solved, especially the failure of the anti-leakage system caused by high drop impact (such as damage to the sealing ring, falling of the cap, etc.). At the same time, in the manufacturing process, the manufacturing is simplified by eliminating the manufacturing steps for adding protective materials; the user experience is further improved through a simple structure and convenient operation. As for the product itself, the present application saves protective materials, such as air caps, airbags, foam caps, etc., reducing costs, and the structure can better reduce the drop pressure, so that the product will not leak.

[0036] The present application provides a bottle cap 1 and a bottle having the bottle cap. FIG1 is a front view of a bottle cap according to an exemplary embodiment of the present disclosure. FIG2 is a bottom view of a bottle cap according to another exemplary embodiment of the present disclosure. FIG3 is a perspective view of a bottle cap according to another exemplary embodiment of the present disclosure.

[0037] As shown in Figures 1 to 3, the bottle cap 1 may include: a bottle cap body 11, the bottle cap body 11 includes a cap 111, the cap 111 is used to accommodate and cover the bottle mouth or an accessory connected to the bottle mouth; a bottle cap wall 12, the bottle cap wall 12 extends from the bottle cap body 11 and is cylindrical; and a support ring 13, the support ring 13 is arranged on the bottle cap wall 12 and is spaced apart from the bottle cap body 11 in the axial direction of the bottle cap wall 12, and extends outward in a direction perpendicular to the outer surface of the bottle cap wall 12, the support ring 13 is arranged between the bottle cap body 11 and the end of the bottle cap wall 12 away from the bottle cap body 11, wherein the support ring 13 abuts against the bottle mouth or an accessory connected to the bottle mouth when the bottle cap is tightened.

[0038] In a preferred embodiment of the present application, the bottle cap body 11 of the bottle cap 1 includes a cap 111 and a receiving space provided in the cap 111. The top surface of the cap 111 adopts a non-planar structure. For example, when viewed from a cross section, the top surface of the cap 111 is made into a wavy shape, or a curved shape with alternating concave and convex shapes. When viewed from a top view, the top surface is a plurality of nested circles, preferably a plurality of concentric circles. Overall, the top surface of the cap 111 is a curved surface of a plurality of concentric circles that are continuously curved. The cap 111 with the above-mentioned structure can be better elastically deformed, thereby making it easier to recover the deformation of the bottle cap when the bottle falls from a height.

[0039] In one embodiment of the present application, the cap 111 includes a first portion away from the support ring 13 and a second portion close to the support ring 13, and the wall thickness of the second portion of the cap 111 is greater than the wall thickness of the first portion. In other words, as shown in Figure 1, the bottle cap can be spatially divided into an upper layer 1111, a middle layer 1112, and a lower layer 1113. The first portion can include the upper layer 1111 and the middle layer 1112, and the second portion can include the lower layer 1113. Alternatively, the first portion can include only the upper layer 1111, and the second portion can include the middle layer 1112 and the lower layer 1113. Alternatively, the first portion can include the upper layer 1111 and a portion of the middle layer 1112, and the second portion can include the remaining portion of the middle layer 1112 and the lower layer 1113. In other words, the thickness of the bottle cap is thinner in the upper layer and thicker in the lower layer, and the minimum thickness of the bottle cap body 11 can be 1.3 mm. This structure can improve the elastic deformation performance of the bottle cap, absorb the impact of falling, reserve a larger deformation amount, and further make it easier for the bottle cap to recover from deformation when the bottle falls from a high altitude.

[0040] In a preferred embodiment of the present application, the caps 111 all adopt a triangular splicing structure. That is, as shown in Figures 1-3, from the outer surface, in some embodiments, the caps of the present invention are diamond-shaped caps comprising upper, middle and lower diamond facets. Preferably, any one of the upper, middle and lower diamond facets contains at least 20 triangular or quadrilateral diamond facets. Preferably, any one of the upper, middle and lower diamond facets contains at least 12 quadrilateral diamond facets or at least 20 triangular diamond facets, preferably, wherein the upper, middle and lower diamond facets respectively contain 20 to 30 triangular diamond facets, 24 to 40 triangular diamond facets and 24 to 40 triangular diamond facets. The diamond-shaped cap according to the present invention can provide additional benefits, including further improving the anti-leakage effect.

[0041] In a preferred embodiment of the present application, graduated markings are provided on the wall of the bottle cap body 11 to indicate the volume of the contents in the bottle cap body 11. Alternatively, graduated markings are provided on the inner or outer surface of the bottle cap. On the one hand, when the user is using the bottle, the graduated markings clearly indicate the amount of liquid poured into the bottle. On the other hand, the placement of the graduated markings in specific positions can simultaneously indicate whether the bottle cap is correctly screwed into place, which can greatly improve inspection efficiency during product delivery inspection.

[0042] In one embodiment of the present application, the bottle cap wall 12 extends from the bottle cap body 11 in a direction away from the accommodation space and is generally cylindrical. The bottle cap wall 12 can be made integrally with the bottle cap body 11. As shown in Figures 1 and 3, a support ring 13 is formed on the outer surface of the bottle cap wall 12. Relative to the free end 14 of the bottle cap wall 12 (the end of the bottle cap wall 12 not connected to the bottle cap body 11), the support ring 13 is located on the bottle cap wall 12 closer to the bottle cap body 11.

[0043] The support ring 13 extends a certain width in the radial direction of the bottle cap wall 12. In other words, the support ring 13 extends a certain distance outward perpendicular to the outer surface of the bottle cap wall 12, giving the support ring 13 a generally circular shape. The distance that the support ring 13 extends from the outer surface of the bottle cap wall can be referred to as the width of the support ring 13. The distance that the support ring 13 extends in the axial direction of the bottle cap wall 12 can be referred to as the thickness of the support ring 13.

[0044] In one embodiment, the width of the support ring 13 is close to the width of the lower portion of the bottle cap body 11. That is, in a top view, the diameter of the support ring 13 is roughly equal to the diameter of the lower portion of the bottle cap body 11. Preferably, when the diameter of the bottle cap wall is 40mm, a distance within the range of 5mm to 9mm is extended. In other embodiments, the diameter of the bottle cap wall can be 20-30mm, or other numerical values, in which case the distance extended by the support ring will change accordingly. However, it basically conforms to the rule that the ratio of the diameter of the support ring to the diameter of the bottle cap wall is between 1.3-1.8.

[0045] The diameter of the support ring 13 is typically between 11.5 mm and 85 mm, and the minimum thickness of the support ring 13 can be 1 mm. The ratio of the width to thickness of the support ring 13 is greater than or equal to 5. Most preferably, the ratio is equal to 6, and most preferably, equal to 6.14. The ratio of the width of the support ring 13 to the diameter of the bottle cap wall 12 is greater than or equal to 0.15, and most preferably, equal to 0.2, 0.21, or 0.217.

[0046] The support ring 13 in the present application has a wider width, so that it can contact the bottle or the bottle accessories with a larger area, and the bottle cap can withstand less pressure, so that the force borne by the bottle cap can be better transmitted to the bottle body. The bottle body is more flexible and easier to deform to absorb the impact of falling, and ultimately better prevent leakage.

[0047] In one embodiment of the present application, the lower surface of the support ring 13 can be a smooth plane. Alternatively, one or more circles of annular grooves (not shown) are provided on the lower surface of the support ring 13, or one or more circles of annular ribs are provided. In other words, when viewed from the bottom of the bottle cap upward, a plurality of ribs or grooves are provided on the lower surface of the support ring 13. Alternatively, a spirally expanded groove or rib is provided on the lower surface of the support ring 13. Alternatively, a plurality of concentric grooves or ribs are provided on the lower surface of the support ring 13. When the bottle cap is tightened to the bottle, the support ring 13 with the grooves or ribs can contact the bottle mouth or other accessories connected to the bottle, and the grooves or ribs can be used as sealing rings, thereby better preventing the liquid or other substances in the bottle from leaking.

[0048] In one embodiment of the present application, as shown in Figures 1-3, the support ring 13 protrudes one or more snap protrusions 131 outward from its circumferential edge in its circumferential direction. Preferably, two symmetrically distributed snap protrusions 131 are provided. The shape of the snap protrusions 131 can be rectangular, square or other shapes that are convenient for snapping together. When the bottle cap is placed on the bottle and screwed, as the bottle cap is continuously screwed in, when the bottle cap can no longer be screwed, the snap protrusions 131 rotate into place, and at this time, the bottle cap and the bottle are in the most intimate contact and fixed. When the user screws the bottle cap during this period, the snap protrusions 131 can be manually sensed to be in place, or the snap protrusions 131 can be identified by the click of the buckle to see whether they have been correctly rotated into place without further screwing.

[0049] In one embodiment of the present application, as shown in Figures 1-3, a support ring 13 is provided on the bottle cap wall 12, and in the figure, the support ring 13 separates the bottle cap wall 12 into two sections, namely, a first section 121 (which can also be described as the first section between the end of the bottle cap body 11 and the support ring 13) from the position where the bottle cap wall 12 contacts the bottle cap body 11, and a second section 122 (which can also be described as the first section) from the support ring 13 to the free end 14 of the bottle cap wall 12 (the end farthest from the bottle cap body 11), and the length of the first section 121 is much smaller than the length of the second section 122. The second section 122 can serve as a buffer zone for the bottle cap. The longer the length of this section along the axis of the bottle cap, the better the cushioning can be provided for the bottle, making it easier for the bottle cap to deform to absorb the impact of a drop. In addition, by arranging the sealing ring 15 close to the bottle cap body 11, the second section 122 of the bottle cap wall 12 can have a larger surface area, thereby providing a larger design space for the threads provided thereon.

[0050] In one embodiment of the present application, as shown in Figures 1-3, a circle of sealing ring 15 is provided on the outer surface of the free end 14 of the bottle cap wall 12. Alternatively, multiple circles of sealing ring 15 are provided on the outer surface of the free end 14 of the bottle cap wall 12. The sealing ring 15 can be integrally formed with the bottle cap wall 12. The direction in which the sealing ring 15 protrudes is the same as the direction in which the support ring 13 protrudes, that is, it protrudes radially outward from the outer surface of the bottle cap wall 12. The distance between the sealing ring 15 and the support ring 13 can be greater than 10mm, greater than 15mm, greater than 18mm, greater than 20mm, and even most preferably, can be greater than or equal to 21.3mm. Through this structure of the sealing ring 15, a secondary seal can be provided for the bottle cap, thereby further preventing the liquid in the bottle from leaking.

[0051] In one embodiment of the present application, threads for screwing onto the bottle can be provided within the second section 122 of the bottle cap wall 12. These threads are provided on the outer surface of the bottle cap wall 12 and can be integrally formed with the bottle cap wall 12. Because the support ring 13 is closer to the bottle cap body 11, the length and surface area of ​​the second section 122 of the bottle cap wall 12 are significantly increased. The distance from the threads to the sealing ring 15 on the bottle cap wall 12 can be 5 mm, allowing one or more threads to be provided on this section. This threaded arrangement allows for a more secure connection between the bottle cap and the bottle.

[0052] In one embodiment of the present application, the outer surface of the bottle cap wall 12 may be provided with one, two, or one and a half turns of thread. In other words, the outer surface of the bottle cap wall 12 may be provided with one, one and a half, or two turns of thread around the axis of the bottle cap wall 12. The thread includes a starting segment 161, an ending segment 163, and an intermediate segment 162 located between the starting segment 161 and the ending segment 163. When the bottle cap wall 12 is unfolded into a plane, the thread is also unfolded into a straight line segment comprising the ending segment 163, the intermediate segment 162, and the starting segment 161, extending roughly from the lower left to the upper right, with a gap separating the starting segment 161 and the intermediate segment 162, and a gap separating the intermediate segment 162 and the ending segment 163. In other words, a turn of thread may be interrupted once in the middle, leaving a gap. Preferably, a turn of thread may be interrupted twice, leaving two gaps. Alternatively, the thread may be interrupted three or more times, with three or more gaps.

[0053] In another preferred embodiment of the present application, a wide thread 16 may be provided on the second section 122 of the bottle cap wall 12, as shown in Figures 1-3. The wide thread 16 not only provides an increased contact area with the bottle, allowing the thread contact to be in a very secure position, but also further reduces the impact of a drop. For example, the crest width of the wide thread 16 may be 2-5 times the crest width of a conventional or standard thread. Preferably, the crest width of the wide thread 16 may be three times the crest width of a conventional or standard thread, while the crest diameter and root diameter may be similar to those of a conventional or standard thread.

[0054] In one embodiment of the present application, the thickness of the starting section 161 of the thread varies greatly, that is, it rises from the outer surface of the bottle cap wall 12 to the top surface of the thread within a small distance. This steep change in the starting section 161 of the thread can prevent the thread from deforming and collapsing during the manufacturing process, and can cooperate with the bottle mouth more smoothly and firmly during the screwing process. It can also ensure that during the production of washing products, the capping process on the packaging line is easy, with good production technology, and the possibility of failure during the production process is reduced.

[0055] In one embodiment of the present application, a plurality of dimples 17 may be provided on the top surface of the intermediate segment 162 and / or the final segment 163 of the thread, with the depth of the dimples 17 gradually increasing in the direction of thread engagement. The dimples 17 may be in the form of round holes, grooves, or the like. Specifically, the top surface of the initial segment 161 of the thread may not have dimples 17, while the top surfaces of both the intermediate segment 162 and the final segment 163 of the thread may have dimples 17. In the illustration shown in FIG2 , the depth of the dimples 17 on the top surfaces of the intermediate segment 162 and the final segment 163 gradually increases from right to left.

[0056] In another embodiment of the present application, the pit 17 may not be set on the top surface of the starting section 161 and the middle section 162 of the thread, and the pit 17 may be set on the top surface of the ending section 163 of the thread. In the illustration shown in Figure 2, the depth of the pit 17 on the top surface of the ending section 163 gradually increases from right to left.

[0057] The thickness of the thread refers to the distance of the thread on the normal line of the outer surface of the bottle cap wall 12. In other words, the thickness of the thread refers to the distance from the outer surface of the bottle cap wall 12 to the top surface of the thread (also known as the crest surface of the thread). The depth of the pit 17 refers to the distance of the pit 17 on the normal line of the outer surface of the bottle cap wall 12. In other words, the depth of the pit 17 refers to the distance from the top surface of the thread. In one embodiment of the present application, the maximum depth of the pit 17 is less than the thickness of the thread. Preferably, the ratio of the maximum depth of the pit 17 to the thickness of the thread is less than or equal to 0.8.

[0058] The pit 17 in the thread can be integrally formed during the thread molding process, and the pit 17 helps prevent the thread from collapsing during the thread molding process, thereby better forming a wider and thicker thread, thereby enabling a smoother and more secure connection between the bottle cap and the bottle to prevent leakage of the liquid in the bottle.

[0059] In a preferred embodiment, the ratio between the distance from the support ring 13 to the sealing ring 15 and the diameter of the arc surface on which the outer surface of the bottle cap wall 12 is located is greater than or equal to 0.5, preferably, greater than or equal to 0.6. In other words, the ratio between the distance from the support ring 13 to the sealing ring 15 and the thread bottom diameter (the diameter of the plane on which the thread bottom is located) at the bottle cap wall 12 is greater than or equal to 0.5 or 0.6.

[0060] The support ring 13 with the above-described structure allows for a larger area of ​​contact with the bottle mouth or other accessories connected to the bottle. This structure not only strengthens the bottle cap, making it sufficiently strong to protect the bottle mouth, but also provides a larger contact area with the bottle, reducing the impact of a drop. Furthermore, when the bottle falls, the impact of the drop is transferred from the bottle cap to the bottle. Compared to other components, the bottle is more flexible and can deform more easily to absorb the drop impact.

[0061] In one embodiment of the present application, a buckle and wide thread 16 are provided on the support ring 13 of the bottle cap wall 12 to prevent the thread from slipping when the bottle cap is screwed on. Slipping can occur for many reasons, such as incorrect installation resulting in improper thread alignment, deformation or damage to the thread due to overtightening, and inability to withstand the corresponding torque due to mismatch between the screw and the connector. By combining the buckle and wide thread 16, not only can the threads be correctly aligned to avoid incorrect installation angles, but the user can also be prompted by touch or hearing to rotate the cap into position, avoiding slipping caused by overtightening.

[0062] As shown in Figures 4(a) and 4(b), during packaging line testing, the bottle cap of the present application exhibited superior anti-slip properties compared to prior art products. Using a capping force of 600 Ncm, the prior art cap slipped, while the bottle cap of the present application remained securely attached to the bottle.

[0063] In one embodiment of the present application, the distance from the thread to the free end 14 of the bottle cap wall 12 can be one-quarter of the entire length of the bottle cap wall 12. This allows the bottle cap wall 12 of the present application to have a sufficiently large surface area to accommodate wide and thick threads, thereby providing a larger contact area with the bottle mouth and further improving the performance of preventing liquid leakage. In addition, it provides the possibility of a better manufacturing process and reduces the possibility of failure during the production process.

[0064] In one embodiment of the present application, the bottle cap can be transparent to facilitate the user to observe the situation of the liquid contained in the bottle cap, or the bottle cap can be other colors to increase the visual effect of the bottle cap. The bottle cap as a whole can be made of plastic material, for example, made of high-density polyethylene.

[0065] In addition, in one embodiment, the bottle cap body 11, the support ring 13, the bottle cap wall 12 and the sealing ring 15 can be made in one piece. The length of the bottle cap wall 12 is significantly longer than that of the bottle cap wall 12 in the prior art, for example, equal to or greater than the height of the bottle cap body 11.

[0066] During the transportation inspection, the bottle caps of the present application still have an excellent anti-leakage effect compared with the products in the prior art. There are 40 boxes of bottles with the above-mentioned bottle cap structure of the present application, each box is loaded with 4 bottles of products, and each product bottle is filled with 3 kilograms of liquid. There are 39 boxes of products with the prior art structure (for example, equipped with air caps), each box is loaded with 4 bottles of products, and each product bottle is filled with 3 kilograms of liquid. After normal logistics transportation, the bottles with the above-mentioned bottle cap structure of the present application did not leak, while 50% of the bottles in the prior art products leaked. Through comparison, it can be clearly seen that the bottle caps of the present application can achieve a very significant anti-leakage effect.

[0067] During the drop test, 12 bottles were filled with 3 kg of liquid and capped with the bottle caps having the structure described in this application. The test results showed that none of the 12 bottles leaked, and the bottle caps did not deform. In existing products, all the bottle caps deformed, with approximately 25% of the bottles deforming and even leaking. This comparison clearly shows that the bottle caps described in this application and bottles equipped with them achieve a very significant leak-proof effect.

[0068] The present application also provides a bottle for carrying fluid, which includes the leak-proof bottle cap as described above. Preferably, the bottle also includes the leak-proof bottle cap as described above and an accessory for connecting the leak-proof bottle cap to the bottle.
