Description

Technical Field

[0001] This invention relates to an environmentally friendly bottle cap for use as an opening or closing container opening, and more particularly to an environmentally friendly bottle cap that can prevent separation from the container during use as an opening or closing container opening, and can also be completely separated as needed for processing for reuse. Background Technology

[0002] Generally speaking, bottle caps attached to the opening of plastic containers used for holding beverages such as mineral water, juice, and carbonated drinks will break off at the bottom part during the initial separation from the container.

[0003] That is, the bottle caps used in plastic containers are made in a shape where the lower part is easily broken off. As a result, a part of the bottle cap that has separated in a ring shape will remain on the opening side of the plastic container when the user opens it.

[0004] Because this part is made of a different material than the plastic container, it must be removed during the recycling process. Although it can be removed by crushing it together with the plastic container and then using the density difference, from the perspective of recycling efficiency, it is better to remove it directly in the home or other places before discarding it.

[0005] However, the cap residue left in plastic containers cannot be easily removed without tools, so a large number of plastic containers are actually discarded directly along with the cap. Even when the cap is removed, its small size makes it difficult to reuse.

[0006] In addition, bottle caps that are completely detached from plastic containers may be lost due to user carelessness or become contaminated from falling to the ground, thus causing the inconvenience of having to hold the bottle cap while drinking the beverage.

[0007] Therefore, there is an urgent need to solve the problems mentioned above. As a result of the research and development expected to be related, an invention entitled "Environmentally friendly bottle cap with improved usability" was proposed and disclosed in Korean Patent Registration No. 10-2258555.

[0008] That is, in the prior art, a bottle cap is proposed that allows the upper and lower rings forming the lower part to remain connected to the opening of the container even when the main body is separated from the opening of the container, thereby achieving the effect of preventing loss and contamination. Furthermore, a portion of the lower ring can be broken off by external force, thereby achieving the effect of easily separating and discarding the whole bottle cap.

[0009] However, the actual implementation of the prior invention as described above has revealed not only the problem that the main body comes into contact with the user's face during the drinking process due to the close distance between the container opening and the main body separated from it, but also the problem that the upper ring is blocked by the opening and becomes an obstacle during the process of reassembling the separated main body into the container opening.

[0010] That is, although the bottle cap proposed in the prior invention mentioned above is for environmental protection and to improve usability, from the perspective of usability, it is still in a state where several parts need to be improved.

[0011] Therefore, there is a need for an improved bottle cap invention that, while maintaining all or most of the same components as those proposed in the prior art as described above, solves all the problems that need improvement, and thus has no inconvenience in use. Summary of the Invention

[0012] (a) Technical problems to be solved This invention is proposed to solve the many problems found in the prior art as described above.

[0013] In summary, the close proximity between the container opening and the detached main body could potentially lead to contact between the main body and the user's face while drinking. Furthermore, during the process of reassembling the completely separated main body into the container opening, the upper ring may be blocked by the opening, thus creating an obstacle. Therefore, the purpose is to propose a solution to the problem described above.

[0014] (II) Technical Solution To achieve the objectives described above, the present invention provides an environmentally friendly bottle cap with anti-loss and complete detachment from the container, characterized in that it comprises: The main body is cylindrical with threads formed on its inner circumferential surface and an open lower end that can be joined to or separated from a container opening; the upper ring is configured with a first circular fracture portion formed on one side that can be broken during rotation, a connecting portion for preventing separation from the lower end of the main body, and a second fracture portion that can be broken during tension; and the lower ring is configured with a third circular fracture portion formed on one side that can be broken during rotation and a fourth fracture portion that can be broken during tension.

[0015] At this point, the present invention is characterized in that: the upper ring and the lower ring are configured such that, based on the vertical cross-section of the entire body, a portion of the body is connected to each other in the opposite direction of the connecting portion.

[0016] Furthermore, the present invention is characterized in that the second fracture portion and the fourth fracture portion are constructed in opposite directions to each other, based on the vertical cross-section of the entire body.

[0017] (III) Beneficial Effects The present invention provides an environmentally friendly bottle cap that features anti-loss and complete detachment from the container. As described in the prior art, bottle caps used for opening or closing container openings can be prevented from being lost, and can also be completely separated from the container as needed, thereby achieving the effect of assisting in reuse for environmental protection.

[0018] Furthermore, compared to prior art, a portion of the upper ring can be additionally broken, thereby achieving the effect that the main body will not come into contact with the user's face while the user is drinking the beverage, and further achieving the effect that the upper ring will not cause any obstruction when the main body is reassembled from the container opening.

[0024] An environmentally friendly bottle cap according to the present invention, which has the functions of preventing loss and being completely detachable from the container, is characterized in that it comprises: The main body is cylindrical with threads formed on its inner circumferential surface and an open lower end that can be joined to or separated from a container opening; the upper ring is configured with a first circular fracture portion formed on one side that can be broken during rotation, a connecting portion for preventing separation from the lower end of the main body, and a second fracture portion that can be broken during tension; and the lower ring is configured with a third circular fracture portion formed on one side that can be broken during rotation and a fourth fracture portion that can be broken during tension. Detailed Implementation

[0025] This invention relates to an environmentally friendly bottle cap used for opening or closing a container opening, characterized in that it comprises: The main body 100 is cylindrical and has threads formed on its inner circumferential surface. It is open at the lower end and can be connected to or separated from the opening of container B. The upper ring 110 is configured to have a first fracture portion 111 formed on one side that can be broken by rotation and a connecting portion 112 for preventing separation, which allows a portion to be separated from the lower end of the main body 100, and a second fracture portion 113 that can be broken by stretching. The lower ring 120 is configured to have a third fracture portion 121 formed on one side that can be broken by rotation and a fourth fracture portion 122 that can be broken by stretching, which allows a portion to be separated from the lower end of the upper ring 110.

[0026] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0027] First, the main body 100 is a cylindrical component with an open lower end and a thread or multiple curved protrusions formed on its inner circumferential surface. It is made entirely of plastic material and is used to open or close the opening formed on the upper part of the container B.

[0028] That is, the main body 100 can be made of a type of plastic, namely high-density polyethylene (HDPE), and can be attached to or separated from the opening of the container B in a state that corresponds to the shape of the opening of the container B with threads formed on its outer peripheral surface.

[0029] At this time, although the container B to which the present invention is applicable should mostly be a type of plastic, namely a container commonly known as a PET bottle made of polyethylene terephthalate (PET), there are no limitations on the material of container B. Therefore, the present invention can also be applied to other types of plastic containers or paper containers without any problems.

[0030] In addition, the main body 100 needs to protrude a circular leak-proof flange from the top surface of the inside downward for a certain length. By embedding the end of the opening of container B into the space between the leak-proof flange and the inner wall surface, leakage of beverages caused by changes in the posture of container B can be completely prevented.

[0031] Furthermore, on the outer peripheral surface of the body 100, which is formed by a curved surface, a plurality of protrusions are formed in a horizontal or vertical shape along its periphery, thereby increasing the friction with the fingers when the user rotates the container B to open or close the opening.

[0032] Therefore, users can use it in the same way as a bottle cap of a regular plastic container, by holding the main body 100 and placing it on the opening of container B and rotating it clockwise to securely attach it, or by rotating the main body 100 attached to the opening of container B counterclockwise to detach it.

[0033] However, even when the main body 100 is separated from the opening of the container B, it does not immediately detach from the container like a typical plastic bottle cap. Instead, the upper ring 110 and the lower ring 120 allow the main body 100 to remain connected to the container B, thereby preventing problems such as loss or contamination from falling to the ground.

[0034] That is, such as Figure 1a as well as Figure 1b As shown, the upper ring 110 is a ring-shaped component located on the lower side of the main body 100, which can prevent the environmentally friendly bottle cap, including the main body 100, from detaching from the container B, while expanding the range of motion of the main body 100 separated from the opening of the container B.

[0035] More specifically, the upper ring 110 is constructed by using a circular first fracture portion 111 and a connecting portion 112 for preventing separation to connect to the lower end of the main body 100, as shown in the figure. Figure 2a as well as Figure 2b As shown, the rotation of the main body 100 is restricted by combining it in a form that encloses the opening of container B.

[0036] However, when subjected to an external force capable of causing the main body 100 to rotate independently, such as Figure 2c As shown, the first fracture portion 111 will fracture, and as a result, most of it can be separated from the lower end of the main body 100.

[0037] Therefore, in order to easily break when the user performs the action of holding the main body 100 connected to the opening of container B and rotating it, the first fracture portion 111 needs to be configured in the form of multiple connection points that connect the lower end of the main body 100 to the upper end of the upper ring 110 at certain intervals, and its fracture strength benchmark can be the same as or to the same degree as that of a general plastic container cap.

[0038] However, unlike ordinary plastic container caps, even if the first fracture portion 111 breaks, the main body 100 will not detach from the container B. Instead, it is configured such that the connection between the main body 100 and the upper ring 110 can be maintained by the unbroken connecting portion 112.

[0039] That is, the present invention does not cause problems such as loss of the main body 100 or contamination due to falling to the ground, but achieves the effect of allowing the opening of container B to be closed again after the user drinks the beverage.

[0040] At this time, as Figure 1a as well as Figure 3 As shown, the connecting part 112 can be formed in a straight line or a rhombus shape to simplify the mold making or manufacturing process. In the case of a rhombus shape, the main body 100 can be easily folded in the opposite direction from the opening of container B by forming a "<" shaped cutting groove 123 on one side.

[0041] In addition, the fracture strength can be improved by hot-melt adhesive with a thickness of 0.45 to 1 mm being hot-melted onto the outer peripheral surface of the connecting part 112, thereby preventing fracture from occurring or easily caused by external forces or fatigue when the main body 100 rotates.

[0042] Furthermore, the present invention is characterized by the formation of a second fracture portion 113 on one side of the upper ring 110, which causes additional fracture under certain conditions, thereby transforming a part of the main body into a shape that is separated from each other.

[0043] like Figure 2d as well as Figure 2e As shown, the second fracture portion 113 as a whole can be broken by the external force, namely the tensile force, applied when the user holds the main body 100 which is separated from the opening of container B and performs a pulling action. Therefore, the shape of the upper ring 110 can be transformed into a curved shape.

[0044] At this time, the second fracture portion 113 can also be configured with multiple connection points in the same way as the first fracture portion 111. However, since it cannot break simultaneously when subjected to external force, it is preferable that its connection points be formed in a more robust form compared to the first fracture portion 111.

[0045] Therefore, compared to the case where the upper ring 110 maintains a circular shape, the main body 100 can be located further away from the opening of the container B, which results in the main body 100 not coming into contact with the user's face while the user is drinking the beverage.

[0046] Furthermore, the upper ring 110, which is broken on one side, can be easily reattached to the opening of container B, thus making the process of reattaching the main body 100 to the opening of container B easier than before.

[0047] That is, when the upper ring 110 is intact, during the process of reassembling the main body, which is completely separated from the container opening, back into the opening, the upper ring 110 may be blocked. However, when one side of the upper ring 110 is broken, the problem described above will not occur.

[0048] In addition, such as Figure 1a as well as Figure 1b As shown, the lower ring 120 is a ring-shaped component located on the lower side of the upper ring 110, and is used to prevent the environmentally friendly bottle cap, including the main body 100, from detaching from the container B by being linked with the upper ring 110.

[0049] More specifically, the lower ring 120 is integrally connected to the lower end of the upper ring 110 by utilizing a part of the main body that is directly connected and the circular third fracture portion 121, as shown in the example. Figure 2c As shown, the third fracture portion 121 fractures as a whole when the main body 100, which is connected to the opening of container B, is rotated, and most of it can be separated from its lower end.

[0050] Therefore, in order to easily break when the user performs the action of grasping the main body 100 which is connected to the opening of container B and rotating it, the third fracture part 121 also needs to be configured to include multiple connection points that connect the lower end of the upper ring 110 to the upper end of the lower ring 120 at certain intervals.

[0051] That is, the first fracture portion 111 and the third fracture portion 121 are configured to include multiple connection points that break when subjected to external force, so that they can break simultaneously when the main body 100, which is connected to the opening of container B, is rotated alone.

[0052] At this time, as a result of being located in different positions, it may be possible for the first fracture portion 111, which is located above and subjected to a relatively larger external force, to fracture, while the third fracture portion 121 does not fracture.

[0053] Therefore, the present invention can cause the first fracture portion 111 and the third fracture portion 121 to fracture simultaneously by making the number of connection points provided in the first fracture portion 111 and the third fracture portion 121 different, or cause the third fracture portion 121 to necessarily enter a fracture state when the first fracture portion 111 fractures.

[0054] As one embodiment of the present invention, the first fracture portion 111 may form 10 to 12 connection points that connect the main body 100 and the upper end of the upper ring 110 and break due to external force, while the third fracture portion 121 may form 6 to 8 connection points that connect the lower end of the upper ring 110 and the upper end of the lower ring 120 and break due to external force.

[0055] As described above, by configuring the first fracture portion 111 with more connection points than the third fracture portion 121, more force is required to cause it to fracture. This prevents the situation described above from occurring where the first fracture portion 111 fractures but the third fracture portion 121 does not. Instead, the first fracture portion 111 fractures simultaneously, or the third fracture portion 121 inevitably fractures when the first fracture portion 111 fractures.

[0056] However, since the lower ring 120 is configured such that a part of the main body is directly connected to the lower part of the upper ring 110, it will still maintain a connection with the upper ring 110 even when the third fracture part 121 is broken.

[0057] Therefore, it will not cause problems such as the loss of the main body 100 or contamination due to falling to the ground, but will achieve the effect of allowing the container B opening to be closed again after the user drinks the beverage.

[0058] At this time, the upper ring 110 and the lower ring 120 are configured with a vertical cross section of the entire invention including the main body 100 as a reference, and a portion of the main body is connected to each other in the opposite direction of the connecting portion 112. Therefore, when the user rotates the main body, the pressure can be evenly applied to the first fracture portion 111 and the third fracture portion 121 as a whole.

[0059] Furthermore, the lower ring 120 is formed with a thickness that is 70 to 80% thinner than that of the main body 100, thus creating a gap with the container B. Therefore, when the user uses the main body 100 to close the opening of the container B again, it will be pulled upwards, thereby making it easy to reseal.

[0060] Furthermore, although the upper ring 110 can be formed with the same thickness as the lower ring 120, the body 100 and the lower ring 120 can also be rigidly connected by forming them with the same thickness as the body 100.

[0061] In addition, such as Figures 2a to 2f As shown, the present invention is characterized by the formation of a fourth fracture portion 122 on one side of the lower ring 120, so that additional fractures can occur under certain conditions, thereby causing a part of the main body to transform into a shape that is separated from each other.

[0062] like Figure 2e as well as Figure 2f As shown, the entire fourth fracture portion 122 can be broken by the tensile force exerted by the external force when the user holds the main body 100 in a state separated from the opening of container B and performs a pulling action, so that the lower ring 120 can be completely separated from the opening of container B.

[0063] At this time, the fourth fracture portion 122 is the same as the second fracture portion 113, and it is preferable to form a connection point that is more robust than that of the first fracture portion 111 and the third fracture portion 121.

[0064] Furthermore, the present invention can prevent the simultaneous fracture of the second fracture portion 113 and the fourth fracture portion 122.

[0065] First, such as Figure 4a As shown, the second fracture portion 113 and the fourth fracture portion 122 can be constructed in opposite directions to each other, based on the vertical cross-section of the entire body 100.

[0066] Furthermore, the second fracture portion 113 and the fourth fracture portion 122 can be formed along the vertical direction with the main body 100 located vertically above the upper ring 110 and the lower ring 120, or they can be formed with one in the vertical direction and the other in the inclined direction.

[0067] As one embodiment of the present invention related to it, such as Figure 4b As shown, the present invention can be configured such that the second fracture portion 113 is formed along an inclined direction with the upper end surface of the main body as a reference, and the fourth fracture portion 122 is formed along a vertical direction.

[0068] At this time, the second fracture portion 113 can be configured in a shape with an inclination of 125°.

[0069] Furthermore, as another embodiment of the present invention, such as Figure 4c As shown, the present invention can be configured such that the second fracture portion 113 is formed along the vertical direction with the upper end surface of the main body as a reference, and the fourth fracture portion 122 is formed along the inclined direction.

[0070] At this time, the fourth fracture portion 122 can be configured in a shape with an inclination of 125°.

[0071] As described above, by making the second fracture portion 113 and the fourth fracture portion 122 form in different directions from each other, it is possible to prevent simultaneous breakage when the user performs the action of pulling or rotating the main body 100, and to achieve sequential breakage along the direction of pulling the main body 100.

[0072] That is, when the user performs a rotational pull on the main body 100 or the upper ring 110 which is separated from the opening of container B, the second fracture portion 113 may break, but the fourth fracture portion 122 may maintain its shape. Then, when the user performs an action to pull the main body 100 or the lower ring 120, the fourth fracture portion 122 may break.

[0073] Conversely, when the main body 100 or the upper ring 110 is pulled apart from the opening of container B, the second fracture portion 113 may break but the fourth fracture portion 122 may maintain its shape. The fourth fracture portion 122 may then break when the user performs an action of rotating and pulling the main body 100 or the lower ring 120 in another direction.

[0074] At this time, as Figures 4a to 4c As shown, both the second fracture portion 113 and the fourth fracture portion 122 can be formed linearly, but they can also be formed as shown in the diagram. Figure 4d As shown, the second fracture portion 113 is formed in a linear shape while the fourth fracture portion 122 is formed in an "S" or other curved shape, thereby more clearly achieving the effect of sequential fracture as described above.

[0075] Furthermore, multiple locking portions 124 can be formed along the inner circumferential surface of the lower ring 120, thereby causing the lower ring 120 to be locked to the opening of container B.

[0076] That is, such as Figure 5 As shown, a plurality of locking portions 124 are formed on the lower ring 120 along the inner circumferential surface, which are spaced apart from each other and whose area gradually decreases towards the end, so that they are locked to the thread formed on the circumferential surface of the opening side of the container B.

[0077] Therefore, the lower ring 120 can remain on the opening side of container B even when the fourth fracture part 122 is broken, but when the user pulls the main body 100 more forcefully, the entire assembly including the main body 100, the upper ring 110, and the lower ring 120 can be completely separated from container B.

[0078] As a result, the present invention can achieve the effect that the environmentally friendly bottle cap, including the main body 100, the upper ring 110 and the lower ring 120, can be completely detached from the opening of container B without leaving any residue.

[0079] The embodiments described above are provided as examples only to fully convey the technical ideas of the present invention to those skilled in the art. The present invention is not limited to the embodiments described above, but can be implemented in other forms.

[0080] To provide a clear explanation of the invention, parts unrelated to the description have been omitted in the accompanying drawings. Furthermore, the width, length, and thickness of the constituent elements may be exaggerated or reduced for convenience in the drawings.

[0081] Furthermore, throughout the specification, the same reference numbers represent the same constituent elements.

[0082] Industry availability This invention prevents the loss of industrial availability of bottle caps used for opening or closing container openings, and also allows for complete separation from the container as needed, thus enabling them to be reused for environmental protection and therefore possessing full industrial availability.
