Description

The present invention relates to a lid fastened to the inlet of a container in which a liquid is stored, and more specifically used as a stopper at the inlet of a container made of plastic, pet resin, glass, steel tube, by the user. When drinking the contents of the container, the stopper is not separated from the container, so it can be easily drunk with one hand, it can be opened and closed repeatedly, and the stopper is completely separated from the container after use for easy recycling. Regarding multipurpose eco-caps that can be planned.

Generally, containers made of plastic, pet resin, glass and steel pipes (hereinafter referred to as "containers") are commercially available with drinks such as water and juice as the main contents and a plastic cap as a stopper. In a container cap, the outer threaded portion of the inlet portion opened to the upper part of the container body and the threaded portion formed inside the cap are in close contact with each other, and after filling the container with the contents, the cap is clockwise. Rotate to seal the container and rotate it counterclockwise to release the seal.

The container cap described above is usually composed of a main body fastened to the container inlet and a lower ring connected to the lower part of the main body and located at the lower part of the container inlet.

In addition, in the conventional container in circulation, the structure of the lid (plug or cap) is completely different from the main body located at the upper part and a part of the lower ring connected to the lower part of the main body even after opening. It is connected so that it will not be separated, and after opening the lid, the main body and the lower ring are almost attached, and when drinking with the mouth, it is inconvenient because the lips touch the lid, so the lid Is completely separated from the container and drunk in most cases.

At this time, the lid of the conventional container is often lost when the user drinks it in a large number of times, and the lid is not completely collected when it is collected for recycling, and the lid is filled with the beverage. In the manufacturing process of sealing the lid, there is a problem that a defective product is generated because the connecting portion connecting the main body and the lower ring is fragile and damaged due to the structure.

In addition, the lid of a conventional container may be completely separated with the lower ring when the user pulls the lid hard to completely separate it from the container, but the lower ring remains below the container inlet. In many cases, only the main body of the lid is separated in this state.

That is, when the lid of a conventional container is discarded and recycled, if the material of the container and the material of the lid are different from each other, a step for removing the lower ring remaining in the container must be performed. There is a problem that the recycling process becomes complicated and the recycling cost increases.

As an example for completely separating the container and the lid from each other as described above, the Korean Registered Practical New Plan No. 0213792 has a bottle stopper configured to be opened by applying a twisting force. A first rupture portion formed along the circumference of the lower end of the stopper and consisting of a rupture line that ruptures when a torsional force is applied, and from any end point of the first rupture portion to the lower end of the bottle stopper. Toward, a bottle stopper is presented which is formed so as to be inclined in the same circumferential direction as the first rupture portion and includes a second rupture portion which can be continuously ruptured when the first rupture portion ruptures. There is.

The bottle stopper of Korea Registered Practical New Plan No. 0213792 has the advantage that the bottle stopper can be completely separated from the container during recycling, but it is inconvenient for the user to touch the user's mouth when drinking. There is a problem that the bottle stopper may be felt, and in order to deal with this, if the user completely separates the bottle stopper from the container, the bottle stopper may be lost during repeated drinking. ..

On the other hand, as an example of preventing the lid from touching the user's mouth during repeated drinking, the Korean Registered Practical New Plan No. 0286407 has a cylindrical structure with one end closed, which is normally used, and has an internal structure. Includes an upper cap with female threads formed on it, and a lower ring that has a circular ring shape integrated with the upper cap and has a large number of small trapezoidal protrusions arranged along the circumference. In a general lid, a ring-shaped circular band is inserted in the middle part between the upper cap and the lower ring to form an intermediate ring, and one circular part of the intermediate ring is cut and the upper part starts from one end of the middle ring. We present a PET bottle lid that is not separated from the PET bottle body and has a structure that connects to the lower end of the cap and connects to the upper end of the lower ring with the other end as the end point.

The PET bottle lid of the above-mentioned Korean registered practical new plan No. 0286407 has the advantage that it is not inconvenient because the lid does not touch the user's mouth when the user drinks, but the lid floats when the user actually drinks. There is a problem that it is inconvenient to drink by touching the face part such as the user's cheeks and jaws, and when the lid is completely separated from the container, the lower ring is not easily separated and remains in the container. , There is a problem that it is difficult to recycle.

Further, in order to solve the problems of the above-mentioned Korean registered practical new proposals No. 0213792 and No. 0286407, the applicant applies to the container body for containing the contents (drinking water, water, etc.) and the neck of the container body. An eco-cap for a container used as a lid for opening and closing a container having a pair of annular protrusions so that a container screw thread is formed on the outer diameter of the inlet forming the portion and an annular groove 24 is formed on the lower portion of the container screw thread. The cap body in which the cap thread threaded corresponding to the container thread is formed inward and upward is connected to the cap body by a cuttable open separation perforation, and the annular groove of the container is formed. The open separation perforation includes a cap fixing ring located at, and further includes a detachment prevention fixing support base that is not cut so as to maintain the connected state between the cap body and the cap fixing ring. The cap fixing ring includes an upper fixing ring that is partially cuttablely connected to the cap body and a lower fixing ring that is cutably connected to the lower part of the upper fixing ring by an open / close separation circular perforation. Including, the opening / closing separation circular perforation is configured to have a structure in which the opening / closing separation circular perforation is not formed in a part of a section so that the upper fixing ring and the lower fixing ring are not completely cut, and the cap is fixed. The ring is a first separation cutting line formed perpendicular to one side of the detachment prevention fixing support base formed between the cap body and the upper fixing ring so that the upper fixing ring can be cut and separated in a strip shape. A second separation cutting line formed vertically on one side of a part of the section in which the opening / closing separation circular perforation is not formed is further formed so that the lower fixing ring can be cut and separated in a strip shape. I have filed an application for "Eco-cap for container" of Korea Public Practical New Plan No. 2015-0001931, which is characterized by being formed and constructed.

However, the Korean public utility model No. 2015-0001931 has a problem that the upper fixing ring is broken when the eco-cap is opened during actual use, and it is drunk like the Korean registered utility model No. 0286407. In this case, there is a problem that the cap body touches the user's face, which is inconvenient, and when the eco-cap is completely separated from the container for recycling, the cap body and the upper fixing ring are completely separated. There is a problem that it is difficult to recycle because there is a problem that the upper fixing ring and the lower fixing ring are completely separated.

That is, the lid of a conventional container is inconvenient to touch the user's face during drinking, or if it is completely separated from the container to eliminate the inconvenience of touching the face, it will be lost during repeated drinking. In addition to the problem that it may be damaged, if it is completely separated from the container at the time of recycling, there is a problem that the ring portion remains in the container and recycling becomes difficult.

The present invention has been made to solve the above-mentioned problems of the prior art, and the problem of the lid of the conventional container, that is, it is inconvenient to touch the user's face when drinking, or it is completely separated. Not only can it be lost if it is drunk repeatedly afterwards, but it also causes trouble to remove the ring part remaining in the container during recycling, and the solution to this is also when drinking repeatedly. The main purpose is to provide a multi-purpose eco-cap that can be easily separated from the container at the time of recycling while avoiding inconvenience by not touching the user's face.

In order to achieve the above object, the present invention is an eco-cap used as a lid for opening and closing an inlet formed in the upper part of the body of a container, and a main body in which a thread is formed on an inner peripheral surface.

The present invention relates to a lid fastened to the inlet of a container in which a liquid is stored, and more specifically, it is used as a stopper at the inlet of a container made of plastic, pet resin, glass, steel tube, but the user can use the container. When drinking the contents of, there is no risk of loss because the stopper is not separated from the container, and since the opening angle of 120 degrees or more can be maintained, the user can easily drink with one hand without inconvenience, and the container This is a technique related to a multipurpose eco-cap that can be easily recycled by easily completely separating the main body 20, the upper ring 30, and the lower ring 40 from the glass.

The configuration for achieving the present invention described above is an eco-cap 10 used as a lid for opening and closing the inlet 64 formed in the upper part of the body 62 of the container 60, and a screw thread is formed on the inner peripheral surface. The main body 20 to be formed, the upper ring 30 connected to the lower part of the main body 20 by the cuttable first rupture portion 22, and the lower ring 40 connected to the lower part of the upper ring 30 by the cuttable second rupture portion 32. The first ruptured portion 22 is configured to include a bent portion 22a formed on the front surface so that the main body 20 and the upper ring 30 are not cut and separated from each other, and the second ruptured portion 32 is included. Is configured to include a connecting portion 32a formed on the back surface so that the upper ring 30 and the lower ring 40 are not cut and separated, and the lower ring 40 has a second rupture portion 32 on one side of the connecting portion 32a. It is characterized by including a breaking groove 42 formed from the lower end of the lower end to the lower end of the lower ring 40.

Further, the bent portion 22a of the present invention is formed to have a length of 5 to 7% of the radius size of the main body 20, and the connecting portion 32a is formed with a length of 5 to 7% of the radius size of the main body 20. The bent portion 22a is characterized in that it is formed to have a length of 10 to 14%, and a "V" -shaped bent groove 22a-1 is formed on the inner side surface of the bent portion 22a and is heat-sealed on the outer peripheral surface. The lower ring 40 is characterized by further containing the hot melt 50, and the lower ring 40 has a plurality of inclined surfaces 44a projecting from the inner peripheral surface and increasing in height toward the outer side on the lower surface. It is characterized in that it is configured to further include a detachment prevention protrusion 44.

First, prior to explaining the present invention, the container 60 made of plastic, pet resin, glass, steel pipe, or the like is generally formed on a body 62 for storing liquid contents and an upper portion of the body 62. It is composed of an inlet 64 having a thread (not shown) on the outer peripheral edge.

The present invention is a multipurpose eco-cap (hereinafter referred to as "cap") 10 used as a lid (plug or cap) for opening and closing an inlet 64 formed in an upper portion of a body 62 of the container 60. As shown in FIGS. 1 and 2, a screw thread corresponding to the thread formed on the outer peripheral edge of the inlet 64 is formed on the inner peripheral edge, and when rotated clockwise, the container 60 is sealed and counterclockwise in the opposite direction. When rotated clockwise, the container 60 is separated from the inlet 64 of the container 60 and the container 60 is opened.

Hereinafter, the present invention will be specifically described with reference to FIGS. 1 to 8 showing embodiments of the present invention.

The main body 20, which is a main component for achieving the present invention, is
A screw thread (not shown) is formed on the inner peripheral surface, and a screw thread corresponding to the screw thread of the inlet 64 formed on the upper part of the body 62 of the container 60 is formed on the inner peripheral surface, and the clock is used. When it rotates clockwise, it moves toward the lower part of the inlet 64 to seal it, and when it rotates counterclockwise, it moves toward the upper part of the inlet 64 and opens it.

At this time, as shown in FIG. 1, a plurality of grooves (not shown) or protrusions (not shown) can be formed on the outer peripheral edge of the main body 20 of the present invention in order to increase the frictional force. The user can easily rotate the main body 20.

Further, the main body 20 of the present invention has a sealing member (not shown) made of synthetic resin fitted to the inner upper part in order to improve airtightness when the inlet 64 of the container 60 is sealed. , It has the same diameter as the inner diameter of the inlet 64, and can further include a sealing protrusion (not shown) projecting downward on the inner upper surface.

The upper ring 30, which is a main component for achieving the present invention, is
The first ruptured portion 22 is connected to the lower portion of the main body 20 by a cuttable first ruptured portion 22, and the first ruptured portion 22 connects the main body 20 and the upper ring 30 as generally shown in the drawings. By connecting them in a discrete manner, when the main body 20 is rotated counterclockwise by the user to open the container 60, a twisting force is generated and the container 60 is broken.

Further, as shown in a) of FIG. 3 and a) of FIG. 4, the first rupture portion 22 is a bent portion formed on the front surface so that the main body 20 and the upper ring 30 are not cut and completely separated from each other. Although it is configured to include 22a, here, the front surface is a reference for explaining the positions of the upper ring 30 and the connecting portion 32a, which will be described in detail later, and is not limited to the front direction, and the first rupture portion. It will be obvious that it is formed in any part of 22.

In connection with the above, the first rupture portion 22 prevents the main body 20 and the upper ring 30 from being completely separated from each other by the bent portion 22a, so that the user can use the main body 20 from the container 60, that is, the inlet 64. The effect of preventing the main body 20 from being lost is realized by allowing the container 60 to be located on the upper side surface of the container 60 without being completely separated.

At this time, when the main body 20 of the present invention rotates counterclockwise to move toward the upper part of the entrance 64 and is completely separated from the entrance 64, the main body 20 is moved to the outside of the entrance 64 by the bent portion 22a. Moves to the lower part, which is the position when it is sealed to the entrance 64, whereby the lower part of the main body 20 is locked to the outer surface of the entrance 64, so that the user can open the mouth to the entrance 64. Since the main body 20 does not touch the face portion such as the mouth when it is applied and drunk, the effect of not feeling inconvenience can be obtained.

That is, in the upper ring 30 of the present invention, when the main body 20 rotates counterclockwise, the first ruptured portion 22 breaks, that is, when the main body 20 is cut, the main body 20 moves together in the upper direction and then the main body 20 moves from the inlet 64. After being completely separated, the bent portion 22a moves downward together with the main body 20 and returns to the original position to realize the above-mentioned effect, whereby the main body 20 is removed from the container 60. Since it is not completely separated, the effect of preventing loss is realized.

Further, the bent portion 22a is characterized in that the length is 5 to 7% of the radius size of the main body 20, which is less than 5% of the radius size of the main body 20. When formed to a length, not only is the main body 20 easily broken to separate the main body 20 and the upper ring 30, but also the main body 20 is easily rotated with reference to the bent portion 22a during drinking, which is inconvenient for the user. I may feel the radius.

Further, if the bent portion 22a is formed to have a length exceeding 7% of the radius size of the main body 20, it is not easily broken and does not rotate easily, so that there is a concern that the main body 20 may be lost and the main body 20 may be easily rotated. However, since the restoring force that the main body 20 tries to move to the original position by the bent portion 22a acts strongly and the main body 20 can touch the face part such as the user's nose when drinking. Since it feels inconvenient, it is preferable that the length is 5 to 7% of the radius size of the main body 20.

In addition, the length of the bent portion 22a pulls the main body 20 strongly in the upward direction in order to completely separate the upper ring 30 and the lower ring 40 described later from the container 60 for recycling. At that time, if it is formed to be less than 5%, there is a problem that the bent portion 22a may be broken first and the upper ring 30 and the lower ring 40 may remain at the inlet 64 portion of the container 60. It is preferably formed at 5% or more of the radius size of 20.

In relation to the above, as shown in FIG. 5, the bent portion 22a is characterized in that a "V" -shaped, more specifically "<" -shaped bent groove 22a-1 is formed on the inner side surface. However, the bent groove 22a-1 realizes an effect of easily folding outward as shown in FIG. 6 when the main body 20 rotates counterclockwise and is separated from the inlet 64. Let me.

That is, the bent groove 22a-1 is for attenuating the restoring force that the main body 20 tries to move to the original position again by the bent portion 22a, and the main body 20 separated from the entrance 64 is the entrance. By easily folding the 64 in the outward direction, it is possible to prevent the main body 20 from touching the face portion when the user drinks.

Further, the depth at which the bent groove 22a-1 is formed in the bent portion 22a is preferably 50 to 70% or less of the thickness of the bent portion 22a, but this is less than 50%. The main body 20 can be easily separated from the upper ring 30, and when it exceeds 70%, the restoring force of the main body 20 to move to the original position becomes too large to be applied to the user's face when drinking. There may be a problem that the main body 20 feels inconvenient to touch, and the depth at which the bent groove is formed in the bent portion is 50 to 70% or less of the thickness of the bent portion 22a. Is preferable.

In connection with the above, the bent portion 22a can be configured to further include a hot melt 50 that is heat-sealed to the outer peripheral surface as shown in FIG. 8, but the hot melt 50 is a commonly used hot. Although the melt 50 is used, it is not only heat-fused to a thickness of 0.5 to 1 mm to improve the strength of the bent portion 22a, but also the main body 20 is bent by the bent portion 22a, that is, in a folded state. Achieve the effect that can be maintained.

That is, the hot melt 50 is inconvenient because the main body 20 is maintained in a state of being bent outward from the entrance 64 with respect to the bent portion 22a so as not to touch the user's face during drinking. It is prevented from being felt and the strength of the bent portion 22a is improved to prevent the bent portion 22a from being broken first when the upper ring 30 and the lower ring 40 described later are completely separated from the container 60. The effect of being able to do is obtained.

In addition, it is obvious that even if the hot melt 50 is formed on the entire outer peripheral surface of the bent portion 22a or a part of the central portion of the outer peripheral surface, the above-mentioned effect can be obtained. Preferably, as shown in FIG. 8, the main body 20 and the upper ring 30 are formed so as to have a height formed up and down, that is, a part of the lower outer peripheral edge of the main body 20 and a part of the upper outer peripheral edge of the upper ring 30. The binding force can be improved.

The lower ring 40, which is a main component for achieving the present invention, is
It is connected to the lower part of the upper ring 30 by a cuttable second rupture part 32, and is formed at the lower part of the inlet 64 when the main body 20 is connected to the inlet 64 as shown in FIG. As shown in FIG. 5, a detachment prevention protrusion 44 located in the locking groove 66 and having an inclined surface 44a whose height increases outward toward the lower surface is projected on the inner peripheral surface, and the main body is projected from the inlet 64. When the 20 is separated, the effect of preventing the main body 20 and the upper ring 30 from being separated from the container 60 and being separated is realized.

That is, in the lower ring 40 of the present invention, when the main body 20 rotates counterclockwise and moves to the upper part, the first ruptured portion 22 is broken by the twisting force generated, and the first ruptured portion 22 is broken. When the main body 20 is separated from the inlet 64 after the second rupture portion 32 is broken by the torsional force generated in the upper ring 30 that rotates together, the detachment prevention protrusion 44 projecting from the inner side surface becomes a locking groove. By being locked to the 66, the main body 20 and the upper ring 30 are prevented from being completely separated from the container 60.

Further, the second rupture portion 32 is configured to include a connecting portion 32a formed on the back surface so that the upper ring 30 and the lower ring 40 are not cut and separated, but the connecting portion 32a precedes. The upper ring 30 and the lower ring 40 are completely separated from each other in the same manner that the bent portion 22a of the first rupture portion 22 described above prevents the main body 20 and the upper ring 30 from being completely separated from each other. By preventing this, the main body 20 is not completely separated from the container 60 when the user drinks, and the effect of preventing the main body 20 from being lost is realized.

At this time, unlike the bent portion 22a described above, the connecting portion 32a is formed so that a bent groove or the like is not formed, that is, a part of the back surface of the upper ring 30 and the lower ring 40 is integrally connected. Therefore, the connection strength is stronger than that of the bent portion 22a, and when the main body 20 is strongly pulled upward during recycling, the lower ring 40 is separated from the locking groove 66 of the container 60 and the present invention is used. The effect of completely separating the cap 10 from the container 60 can be obtained.

In addition, the length at which the connecting portion 32a is formed is preferably formed to be 10 to 14% of the radius size of the main body 20, but this is because the bent portion 22a is formed. There is a difference of about twice as long as it is formed to be 5 to 7% longer than the radius size of the main body 20.

That is, the connecting portion 32a is formed to have a length 1.5 to 2 times longer than the length of the bent portion 22a, which means that the connecting portion 32a is 1 longer than the length of the bent portion 22a. When formed to be less than .5 times, i.e. less than 10% of the radial size of the body 20, the body 20 rotates counterclockwise and moves backwards together as it moves upwards in the inlet 64. Is bent toward the outside of the entrance 64 with reference to the front surface of the upper ring 30 moving in the upper direction, that is, the connecting portion 32a, and the restoring force is weakened by the folding of the upper ring 30, whereby the upper part of the entrance 64 is bent. There is a problem that the main body 20 that has been moved to is not restored in the downward direction, causing inconvenience by touching the user's face.

To explain again, if the connecting portion 32a is formed to have a length less than 10% of the radius size of the main body 20 and the upper ring 30 is returned to the original position, the main body is placed on the user's face when drinking. It is possible to prevent 20 from touching.

Further, when the connecting portion 32a is formed to have a length exceeding twice the length of the bent portion 22a, that is, a length exceeding 14% with respect to the radius size of the main body 20, the upper ring 30 is returned to the original position. Since there is a problem that the restoring force to be moved is too strong to separate the main body 20 from the inlet 64, that is, to open the container 60, the connecting portion 32a is 1 longer than the length of the bent portion 22a. It is preferably formed in a length of 5 to 2 times, that is, 10 to 14% of the radius size of the main body 20.

In connection with the above, the connecting portion 32a is formed on the back surface in the direction opposite to the bending portion 22a, so that the first rupture portion 22 and the second rupture portion 32 are naturally broken by the twisting force. At the same time, when the main body 20 is pulled upward during recycling, the effect of easily breaking the breaking groove 42 described later is realized.

That is, the lower ring 40 of the present invention is configured to include a breaking groove 42 formed from the lower end of the second rupture portion 32 to the lower end of the lower ring 40 on one side of the connecting portion 32a, and will be described in more detail. As shown in FIGS. 3 and 4, the fracture groove 42 is formed from the end of the second rupture portion 32 to the lower end surface of the lower ring 40, in other words, in the lower ring 40, but the second rupture portion It is formed perpendicular to the end of either one side or the other side of 32.

Further, the breaking groove 42 is broken by allowing the lower ring 40 to maintain the ring shape during drinking and pulling the main body 20 upward during recycling, and the cap 10 of the present invention, that is, the main body 20, the upper ring. The effect of ensuring that the 30 and the lower ring 40 are completely separated from the container 60 is realized.

At this time, the breaking groove 42 is preferably formed in a "V" shape on the outer peripheral edge of the lower ring 40, but when the main body 20 is pulled upward, the connecting portion 32a is formed in the upper direction and the inlet 42. It is preferable that the back surface of the lower ring 40, that is, the portion corresponding to the lower portion of the connecting portion 32a, is bent outward to be formed on the outer peripheral edge of the lower ring 40.

In other words, in the breaking groove 42, the upper ring 30, that is, the connecting portion 32a moves upward as the main body 20 moves upward, and the lower ring 40 is locked in the locking groove 66 by the detachment prevention protrusion 44. As a result, the connecting portion 32a breaks in the outward direction of the inlet 64, so that when the breaking groove is formed on the inner peripheral edge of the lower ring 40, the breaking groove 42 can be bent without breaking, but the breaking groove is formed in the lower ring. When formed on the outer peripheral edge of 40, the breaking groove 42 is bent and broken at the same time.

In connection with the above, the plurality of detachment prevention protrusions 44 projecting from the inner peripheral surface of the lower ring 40 of the present invention are outward to the lower surface, that is, outward to the inlet 64, as shown in FIG. When the breaking groove 42 is not broken, the disengagement prevention protrusion 44 is bent downward by the inclined surface 44a to be separated from the locking groove 66 by forming the inclined surface 44a whose height becomes higher toward The eco-cap 10 can be completely separated from the container 60.

Overall, in the eco-cap 10 of the present invention, when the main body 20 is rotated counterclockwise and a twisting force is applied to the first burst portion 22, the twisting force also acts on the upper ring 30 to act on the second burst portion 22. When a torsional force is applied to 32, which breaks the first and second burst portions 22 and 32 and separates the main body 20 from the inlet 64, the main body 20 is bent by the bent portion 22a and the hot melt 50. By maintaining this state, it is possible to eliminate the inconvenience of the main body 20 touching the face portion when the user drinks.

Further, the bent portion 22a of the cap 10 of the present invention not only allows the main body 20 to bend naturally toward the outside of the inlet 64 by the bent groove 22a-1 and the hot melt 50, but also improves the strength. It can be prevented from breaking due to repeated movements, and even when the main body 20 is pulled upward to break the breaking groove 42 of the lower ring 40, it can be prevented from breaking before the breaking groove 42.

Further, if the break groove 42 of the lower ring 40 of the present invention is not broken even if the main body 20 is pulled due to a defect of the break groove 42, the lower ring 40 is locked in the locking groove 66 and naturally moves downward. By allowing it to bend, the effect of allowing the cap 10 to be completely separated from the container 60 can be obtained.

In particular, in the present invention, unlike the Korean public utility model No. 2015-0001931 filed earlier by the applicant, the main body 20 is more stably placed outside the entrance 64 by preventing the upper ring 30 from breaking. The inconvenience when drinking was minimized by allowing the user to maintain a fixed state.

Although the above description has been made with reference to the preferred embodiments of the present invention, the present invention is not limited to these embodiments, and a person having ordinary knowledge in the technical field to which the present invention belongs can give the gist of the present invention. It can be implemented with various changes without deviation.
