Description

Bottle cap Cross-reference to related statements This application claims the benefit of Taiwanese Patent Application Serial No. 104110838, dated April 2, 2015, the subject matter of which is incorporated herein by reference. History of the invention 1. Field of invention This invention relates to a closure, in particular, to a container closure. 2. Description of relevant knowledge In general, the lid of a conventional container is always detached from its container after it is a container. For this reason, a lid that is detached from the container is easily dropped, accidentally thrown away, and / or misplaced / lost. In addition, a lid that is detached and falls to the ground is easily soiled when it comes into contact with the ground or uncontrolled surfaces, and as a result, this lid cannot be used again. Also, discarded or misplaced / lost lids pollute the environment and cause further environmental problems. Therefore, in order to solve these problems, the industry has developed a lid that remains attached to its container even when its container is open. Thus, these lids are prevented from being detached from their container, dropped, accidentally thrown away, and / or lost, from becoming soiled when they come into contact with the ground or uncontrolled surfaces, or from polluting the environment or causing environmental problems. However, currently available closures that have the above features typically require much more complex designs. In particular, these designs typically require more than a few components or structures; for example, in addition to a main body structure for the closures, the designs also require complex attachment structures to attach the closures to their containers once the containers have been opened. In addition, these designs also require a barrier structure to prevent interference with the opening of their containers when open and to ensure that the cap is in the open position whenever the user wants. In addition, the complex connection structures require some difficult physical manipulation by the user to return the caps to the closed and sealed state. In order to produce caps with this type of structure, the materials and component parts used are higher than industry and market standards. The production process of these caps also requires different levels of production of different parts of production machines to create complex connection structures. Accordingly, not only the cost of materials increases, but also the per capita cost of production equipment and manpower. The cost and inefficiency of the production process of these caps are very high and exceed the requirements of the market and industry. Therefore, it is necessary to produce a cap with the above characteristics using a simpler design and structure, using fewer materials, fewer pieces of production equipment, and fewer man-hours, in order to produce a cap that is environmentally friendly, easier to produce, has higher production efficiency, and has much lower production costs. Summary of the invention The object of the present invention is to provide a closure for a container. In particular, compared to conventional closures, the closure provided by the present invention, due to its much simpler design and structure, allows the closure to be placed in an open position relative to its container to be maintained in a connected state to the container. Furthermore, the closure of the subject of the present invention remains in the open position whenever necessary, without any physical manipulation by the user. The closure does not interfere with opening the container in the open position and prevents user intervention when the closure is in the open position. The closure of the subject of the present invention can be easily returned to the sealed and closed position and is also prevented from falling, being lost, being accidentally thrown away, becoming soiled as a result of contact with uncontrolled surfaces or from contamination, damage and detrimental effects on the environment. To achieve this object, the present invention provides a closure for a container, comprising a main body having a top plate and a circular side wall, wherein two opposite sides of the side wall are connected to each other in a circular manner, one portion of the circular wall side being connected to an upper surface of the plate forming a closed end, and the other portion of the circular wall side opposite the closed end forming an open end; and a ring member disposed at the open end of the main body, separated from the main body by a first cut line between the open end of the main body and the ring member, and connected to the main body by a plurality of connecting portions, wherein the two ends of the first cut line are separated by a connecting portion; wherein connecting pins are located along the first cut line, the connecting pins connect the main body and the ring member on both sides of the first cut line, a plurality of second cut lines are located on the main body or the ring, and two sides of the second cut lines do not overlap with the first cut line, and two ends of the plurality of second cut lines and themselves are not connected to them. In this invention, the connecting portion can be formed between the first cutting line and the second cutting lines. The connecting portions can also be formed among the number of second cutting lines. The shape of the connecting portions is not particularly limited. The shape of the connecting portions depends on the shape of the first cutting line and the number of second cutting lines located on the side of the connecting portions. The number of connecting portions is not particularly limited. The distance between each of the plurality of connecting portions is not particularly limited, except that each of the plurality of connecting portions is separated by portions of the number of second cutting lines. In this invention, the number of second cutting lines is not particularly limited. The distance between each of the plurality of second cutting lines is not particularly limited. In addition to the plurality of second cutting lines being located in the main body or the ring member, the plurality of second cutting lines can also extend from the main body to the ring member or extend from the ring part to the main body. Although the plurality of second cutting lines does not overlap with the first cutting line; however, the second cutting lines can be connected to portions of the first cutting line. In addition, portions of the second cutting lines can be parallel to the first cutting line. In this invention, the first cutting line and the number of second cutting lines are not particularly limited. However, the first cutting line and the second cutting lines can be individually preferably straight lines, curved lines, linear lines, arc lines or a combination thereof. The plurality of second cutting lines can also be L-shaped lines, S-shaped lines, Z-shaped lines or a combination thereof, wherein the corners of the second cutting lines are not particularly limited. It is preferable that the corners of the second cutting lines are curved corners, concave corners, sharp corners or a combination thereof. The first cutting line and the second cutting lines can be individually the same line type or different line types. In this invention, the first cutting line and the second cutting lines surround a portion of the side of the circular side wall or ring member, but do not completely surround the circular side wall or ring member. The length of the first cutting line and the second cutting lines of the circular side wall or ring member is not particularly limited. Preferably, the length of the first cut line around the circular side wall or ring member is longer than the length of any of the second cut lines surrounding the circular side wall or ring member. In particular, it is preferred that the first cut line is greater than 4 / 3 of the circular side wall or ring member. More preferably, the first cut line is greater than 5 / 4 of the circular side wall or ring member that it surrounds. On the other hand, it is preferred that the second cut lines are less than 4 / 3 of the circular side wall or ring member, more preferably less than 1 / 2 of the circular side wall or ring member, and more preferably less than 1 / 4 of the circular side wall or ring member. In this invention, the provided cap can be used with any conventional container without any particular limitation, provided that the cap and the container can be mounted on each other. The shape of the cap is not particularly limited. However, it is preferable that the inner side of the cap is circular. The shape of the container is also not particularly limited; however, it is preferable that it has a circular opening. In this invention, the container is a round bottle or a round can, respectively. In this invention, the main body of the provided cap is provided for cooperating with the mouth of a container to control the opening and closing of the container mouth. Specifically, the inner part of the main body is threaded. Through a complementary threaded structure on the outer side of the container mouth, the main body can be opened and closed by screwing on the container mouth. In this invention, when the main part of the cap is opened by screwing it onto the container, the closed end of the main body remains in contact with the opening of the container. Meanwhile, the open end of the main body remains towards the opening of the container and is positioned opposite the opening of the container. As a result, the opening of the container remains in a closed state and the container remains in a sealed state. In this invention, the outer part of the main body of the provided cap can have a ribbed portion. When the container needs to be opened, the ribbed portion can facilitate the force required to rotate and separate the main body and the ring member. In this invention, depending on the actual needs, the first cutting line between the main body and the ring member of the provided cap may have connecting pins for connecting the main body and the ring member. The shape, size, number and spacing of the connecting pins are not particularly limited. When the size and number of the connecting pins of the first cutting line are smaller and the spacing of the connecting pins is larger, the force required to break the connecting pins will be smaller. As a result, it will be easier to separate the main body and the ring member. Conversely, when the size and quantity of the first cutting line connecting pins are larger and the distance between the connecting pins is smaller, the force required to break the connecting pins will be greater. As a result, it will be more difficult to separate the main body and the ring member. In the cap provided by this invention, the second cutting lines do not have connecting pins. In this invention, when the main body of the cap provided by this invention is opened by screwing onto the mouth of the container, since the ring member is installed under a protrusion of the container; therefore, the ring member will not be separated from the mouth of the container. As a result, the connection between the main body separated from the mouth of the container and the ring member allows the main body to remain in a connected state with the container. As a result, the connection between the main body separated from the mouth of the container and the ring member allows the main body to remain in a connected state with the container. In addition, a number of connecting parts can be connected to the main body in an open state. The connecting parts prevent the interference of the mouth of the container. The connecting parts also reduce the free movement of the main body. As a result, when the contents of the container are discharged, the connecting parts can prevent the main body from contacting other objects due to its free movement. The contents remaining in the inner part of the main body cannot be easily spilled out. And since the ring member installed in the mouth of the container can rotate freely; therefore, the connecting parts cannot be easily torn off. In the present invention, the provided closure can be made using any material known in the art without any particular limitation. In particular, plastic materials such as polyester, PET, PE, HDPE, PP, PS, PMMA or PC are preferred. The closure can be made by any process known in the art. The closure production process is preferably by injection molding. The first cutting line and the second cutting lines can be made by any known method without any particular limitation. The first cutting line and the second cutting lines are preferably made by rotary cutting. The cuts are preferably made by a conventional cutting tool or laser cutting. In general, in this invention, using the above-mentioned design and structure, the cap placed on the opening remains connected to the container when it is open to the container. The cap of this invention also remains open when needed without any physical manipulation by the user. The cap does not interfere with opening the container in the open state and the free movement of the cap will be limited and will prevent the cap from falling, getting lost, being accidentally thrown away, getting soiled by contact with uncontrolled surfaces or polluting, damaging or negatively impacting the environment. Other objects, advantages, and novel features of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings.

Detailed description of preferred configuration [Example 1] Figure 1 is a diagram of a three-dimensional schematic diagram showing a closure configuration for a container of the present invention. As seen in Figure 1, the closure 10 of this example includes a main body 1 having a top plate 11 and a circular side wall 12. Two opposing circular side walls 12 are connected to each other in a circular manner. A portion of the circular wall 12 connected to a top surface of the plate 11 forms a closed end 1. The outer periphery of the side wall 12 at one top surface of the plate 11 forms a closed end 1'. The other outer periphery of the side wall 12 on the opposite side of the closed end 1' forms an open end 1'. (See FIG. 3). The cap 10 of this example also includes a ring member 2 located at the open end 1' of the main body 1. The ring member 2 of the main body 1 is separated by a first cut line 3 located between the end 1' of the main body 1 and the ring member 2. The first cut line 3 has connecting pins 31. The connecting pins 31 located along the first cut line 3 connect the main body 1 and the ring member 2 on both sides of the first cut line 3. The two ends of the first cut line 3 are separated by connecting portions 5. The connecting parts 5 connect the main body 1 and the ring member 2 to each other. On one side of the connecting parts 5 are located second cutting lines 4. The second cutting lines 4 are also located on the main body 1 or the ring member 2. The two second ends of the cutting lines 4 and themselves are not connected. The second cutting lines 4 do not overlap with the first cutting line 3. As shown in FIG. 2A , in the present example, the connecting portions 5 are formed between the first cutting line 3 and the second cutting lines 4. In this invention, the shape of the connecting portions 5 is not particularly limited. The shape of the connecting portions 5 depends on the shape of the first cutting line, and the second cutting lines 4 are located on the side of the connecting portions 5. In the present example, the shape of the connecting portions 5 is cubic (as seen in FIG. 3 ). In this invention, the number of the connecting portions 5 is not particularly limited. However, in the present example, the number of the connecting portions 5 is 2. In the present invention, the distance between each connecting portion 5 is not particularly limited. However, in the present example, each of the connecting portions 5 is separated by sections of the number of the second cutting lines 4. In this invention, the number of second cutting lines 4 is not particularly limited. However, in the present example, the number of second cutting lines 4 is 2. As shown in Fig. 2A, only the main part 1 has second cutting lines 4. One of the two second cutting lines 4 is connected to the parts of the first cutting line. In addition, parts of the number of second cutting lines 4 are connected parallel to the first cutting line 3. In this invention, the first cutting line 3 and the number of second cutting lines 4 are not particularly limited. The first cutting line 3 and the second cutting lines 4 can be individually preferably straight lines, curved lines, linear lines, arc lines or a combination thereof. In this example, the first cutting line 3 is a straight line. Many of the second cutting lines 4 can also be preferably L-shaped lines, S-shaped lines, Z-shaped lines or a combination thereof. In the present example, the second cutting lines 4 are L-shaped lines. In this invention, the corners 41 of the second cutting lines 4 are not particularly limited. The corners 41 of the set of second cutting lines 4 are preferably curved corners, concave corners, sharp corners or a combination thereof. In the present example, the corners 41 of the number of second cutting lines 4 are curved corners. In this invention, the first cut line 3 and the second cut lines 4 surround the side wall 12 or the ring member 2, but do not completely surround the opposite side of the circular wall 12 or the ring member 2. The length of the first cut line 3 and the second cut lines 4 of the circular wall 12 or the ring member 2 is not particularly limited. In this example, the length of the first cut line 3 surrounding the top of the circular wall 12 or the ring member 2 is greater than the length of each of the second cut lines 4 that are adjacent to the circular wall 12 or the ring member 2. In the present invention, it is preferred that the first cut line 3 is greater than 4 / 3 of the circular side wall 12 or ring member 2 and greater than 5 / 4 of the circular side wall 12 or ring member 1. In this example, the first cut line 3 is greater than 5 / 4 of the circular side wall 12 or ring member 2.

In the present example, the second cut lines 4 are less than 1 / 5 of the circular side wall 12 or ring member 2. [Example 2] Figure 2B is a schematic diagram showing the configuration of a container lid of the present invention. The lid of the present example and the lid of the present example 1 are identical except that the second cut lines 4 and the second cut lines 4 shown in Figure 2A are opposite each other. However, the direction of movement of the lid opening and the lid shown in Figure 2A are still the same (both are clockwise; this rotation is to the right in Figure 2A or Figure 2B). [Example 3] Figure 2C is a schematic diagram showing the configuration of a container closure of the present invention. The closure of the subject matter of this example and the closure of the subject matter of Example 1 are identical except that only the ring member 2 has the second cut lines 4 and the second cut lines 4 are less than 1 / 5 of the ring member 2. [Example 4] Figure 2D is a schematic diagram showing the configuration of a container lid of the present invention. The subject cap of this example and the subject cap of Example 1 are identical except that the second cut lines 4 are 1, the second cut line 4 is not connected from the main body 1 to the ring member 2 or from the ring member 2 to the main body 1, the second cut line 4 and the first cut line 3, the corners 41 of the second cut line 4 (Z-shaped line) are sharp corners, and the second cut line 4 is less than 1 / 5 of the circular side wall 12 and less than 1 / 5 of the ring member 2. [Example 5] Figure 2E is a schematic diagram showing the configuration of a container lid of the present invention. The subject cover of this example and the subject cover of Example 1 are identical except that the second cut lines are 4 L-shaped lines and the corners of these L-shaped lines are sharp corners. [Example 6] Figure 2F is a schematic diagram showing the configuration of a container lid of the present invention. The subject cover of this example and the subject cover of Example 1 are identical, except that the second cut lines 4 and the first cut line 3 are not parallel to each other. The second cut lines 4 are S-shaped lines. [Example 7] Figure 2G is a schematic diagram showing the configuration of a container lid of the present invention. The subject cap of this example and the subject cap of Example 4 are identical except that the corners 41 of the second cut lines 4 (L-shaped lines) are curved corners and one of the second cut lines 4 is less than 1 / 2 of the circular side wall 12. Figure 3 is a three-dimensional schematic diagram showing a container closure of the present invention being separated from a container, wherein the closure shown can be any of the closures of any of the above examples. In the following, the practical application of the closure provided in the present invention will be explained in detail using the closure of Example 1. In this invention, the provided cap 10 can be used with any conventional container without any particular limitation as long as the cap 10 and the container 20 can be stacked on each other. In this invention, the shape of the cap 10 is not particularly limited. As seen in FIG. 3, the inner side of the cap is circular. In this invention, the shape of the container 20 is also not particularly limited. As seen in FIG. 3, the opening 210 of the container is a circular opening. In this invention, the container 20 is preferably a round bottle or a round can. As seen in FIG. 3, the container 20 is a bottle with a circular opening. The main body 1 of the closure 10 of the present invention controls the opening and closing of the container opening 210. As can be seen in FIG. 3, the interior of the main body 1 has an aperture 110. With a complementary structure 2100 on the exterior of the container opening 210, the main body 1 can be opened (counterclockwise) and closed (clockwise) by twisting (not shown) onto the container opening 210. In this invention, when the main body 1 of the provided cap 10 is closed by screwing onto the container opening 210, the closed end 1' of the main body 1 is in contact with the container opening 210. Meanwhile, the open end 1'' of the main body 1 is opposite to the container opening 210 and the cover is on the container opening 210. As a result, the container opening 210 remains closed with the container 20, and is sealed. In this invention, the outer portion of the main body 1 of the provided cap 10 can have a groove portion 120. When the container 20 is opened, the groove portion 120 can apply a force to rotate the main body 1 and detach the ring member 2. In this invention, depending on actual needs, the first cutting line 3 between the main body 1 and the ring member 2 of the cap 10 provided can have a plurality of connecting pins 31 for connecting the main body 1 and the ring member 2. The shape, size, number and spacing of the connecting pins 31 are not particularly limited. When the size and number of connecting pins 31 of the first cutting line 3 are smaller and the distance between the connecting pins 31 is greater, the force required to break the number of connecting pins 31 will be less. Conversely, when the size and number of the connecting pins 31 of the first cutting line 3 are larger and the distance between the connecting pins 31 is smaller, the force required to break the connecting pins 31 will be larger. In this example, the size and number of the connecting pins 31 of the first cutting line 3 are smaller and the distance between the connecting pins 31 is larger. In addition, the second cutting lines 4 do not have connecting pins. Therefore, the force required to break the connecting pins 31 is smaller. After that, users can more easily separate the main body 1 and the ring member 2. That is, the lid 10 can be easily opened from the opening 210 of the container. In this invention, when the main body 1 of the cap 10 provided by this invention is opened from the opening 210 of the container by twisting, the connecting parts 5 connect the main body 1 and the ring member 2 together. Since the ring member 2 is located under the protruding portion 2200 of the container opening 210, the ring member 2 will not be separated from the container opening 210; therefore, the ring member 2 will not be separated from the container opening 210. As a result, the connection between the main body 1 of the container opening 210 and the ring member 2 is separated, and the main body 1 remains in a connected state with the container 20. In addition, the connecting part 5 can also leave the main body 1 in an open state. The connecting parts 5 prevent the main body 1 from being separated from the container opening 210. The connecting parts 5 also reduce the free movement of the main body 1. As a result, when emptying the contents of the container 20, the connecting parts 5 can prevent the main body 1 from moving. For example, when the container 20 is a water bottle, when users drink from the water bottle, the connecting parts 5 prevent the user's face and any part of the body from contacting the main body 1.In addition, the connecting parts 5 can also prevent the contents from remaining in the inner part of the main body 1 and easily prevent the free movement of the main body 1 from being reduced, and the ring member 2 on the mouth 210 of the container can rotate freely; hence, the connecting parts 5 are not easily torn off. In this invention, the provided cap can be made using any material known in the art, wherein the material for the cap is preferably plastic, such as polyester, PET, PE, HDPE, PP, PS, PMMA or PC. In all the above examples, the material for preparing the cap is PP. The cap can be produced by any process known in the art. In all the above examples, the process for producing the cap is by injection molding. The first cutting line and the second cutting lines can be produced by any method known in the art. In all the above cases, the first cutting line and the second cutting lines are performed by rotary cutting and cutting with a cutting tool or laser cutting. In general, the closure for a container provided by the present invention has a simple design and structure. By using only one first cut line and several second cut lines, a number of connecting parts are formed. The connecting parts formed can connect the container with the lid detached from the container so that the lid is not lost or discarded. The connecting parts formed can also hold the lid in an open position, in which the lid does not interfere with the mouth of the container and the free movement of the lid is reduced. The end result is that the lid has better performance. Unlike conventional lids, the lid of the present invention does not require a barrier structure in order to achieve the same performance as the above lid.
