Definitions
- the present invention relates to a PET container cap with a simultaneously separable end ring and, more particularly, to a PET container cap with a simultaneously separable end ring, in which when a cap body (a cap) provided on and coupled to an injection part of a PET container is separated, an end ring provided on the lower side of the cap body may be separated therewith.
- PET polyethylene terephthalate
- PET container Since the PET container was invented, this was immediately used in the industry due to the boom of a soda drinks and the advantages of the PET material. This container was so booming that 100 billion bottles were produced per year around 1999. At first, this was mostly used as a container for containing liquid such as beverage or sauce. However, recently, the container is used as various package materials for containing alcoholic beverages such as beer or soju as well as eye drops and detergent, so now PET containers have become essential in the living environment of consumers.
- a cap is provided on an injection part (spout) of the PET container to provide tight blocking for preserving contents (food and beverage, etc.) and a sealing function for identifying openness.
- a conventional PET container includes a container body that contains contents, and a cap that is coupled to an injection part of the container body.
- a spiral binding protrusion for fastening the cap and an annular protrusion for preventing the separation of the cap are formed on an outer circumference of the injection part of the container body.
- the cap includes a cap body that seals and tightly blocks the injection part of the container body and an end ring that seals the cap body.
- a spiral protrusion is formed on the inner circumference of the cap body to correspond to a binding protrusion formed on the outer circumference of the injection part, and a plurality of interference protrusions is formed on the inner circumference of the end ring to engage with the annular protrusion formed on the outer circumference of the injection part.
- the interference protrusion on the inner circumference of the end ring engages with the annular protrusion on the outer circumference of the injection part to be thereby constrained. Consequently, the end ring remains in the PET container.
- the PET container and the cap are made of different materials, i.e., PET and PE (high density polyethylene; HDPE).
- PET and PE high density polyethylene
- HDPE high density polyethylene
- the end ring is separated from the PET container in the method of cutting the end ring using a cutting tool such as scissors or nippers.
- a cutting tool such as scissors or nippers.
- the PET container is usually recovered with the end ring remaining. This makes separate garbage collection difficult, so the PET container is thrown away as general waste, thus wasting resources as well as causing environmental pollution.
- Korean Patent Laid-Open Publication No. 10-2012-0101626 has disclosed a structure for removing an end ring of a resin bottle cap and a container having the same.
- the conventional structure for removing the end ring of the resin bottle cap and the container having the same are configured such that a portion of a ring stop upper flange (annular protrusion) for restricting the end ring on an injection part is cut in the shape of a slope to form a guide flange cut part.
- the guide flange cut part should be necessarily formed to achieve the above-described structure for removing the end ring, there is a problem of lack of compatibility that the injection part of the PET container should be manufactured in a shape different from the conventional injection part, which makes it somewhat difficult to apply in practice.
- the present invention has been made to solve the above-mentioned problems and difficulties and relates to a PET container cap with a simultaneously separable end ring, in which the end ring on the lower side of a cap body is transformed in the process of separating the cap body (cap) from an injection part of a PET container, so the restriction force of the end ring (interference protrusion formed on an inner circumference) by an annular protrusion protruding from the outer circumference of the injection part is lost when the cap body is separated, and thus the end ring can also be separated (removed).
- the present invention provides a PET container cap with a simultaneously separable end ring, which provides tight blocking for preservation of contents in a state of being provided on and coupled to an injection part and provides a sealing function enabling awareness of openness, the cap including a cap body provided on and coupled to the injection part to provide tight blocking for preservation of the contents; and an end ring integrally formed on a lower side of the cap body, restricted by an annular protrusion formed on a lower side of an outer circumference of the injection part, exhibiting a sealing function enabling grasping of openness of the cap body, and causing transformation in a separation process of the cap body by a user, so the end ring is simultaneously separated together with the cap body from the injection part.
- the cap body may further include a spiral protrusion formed on an inner circumference of the cap body to correspond to a spiral fastening protrusion formed on the outer circumference of the injection part; and a knurling part formed on an outer circumference of the cap body to prevent a slip when a user holds the cap with his or her hand and rotates the cap clockwise/counterclockwise.
- the end ring may include an interference protrusion formed on an inner circumference of the end ring to engage with a restraint protrusion of the injection part when the cap body is coupled to the injection part; a connecting projection integrally connected to a portion of a lower end of the cap body to cause transformation in a separation process of the cap body; and a sealing projection integrally connected to another portion of the lower end of the cap body to be fractured in the separation process of the cap body and to enable the openness of the cap body to be identified.
- the end ring may include a plurality of cut parts that are cut long to extend from an uppermost end to a lowermost end, are inclined in one direction, and are formed at regular intervals to cause degradation of a ring-shaped preservation ability as a gap is increased by the connecting projection that maintains a connection state with the cap body in the separation process of the cap body.
- the connecting projection may be connected to the cap body to increase the gap of the cut part in the separation process of the cap body, may protrude from an upper end, and may be connected to the lower end of the cap body while extending long from a first end of the cut part to a predetermined range
- the sealing projection may be connected to the cap body, may protrude from an upper end to exhibit the sealing function that enables the openness of the cap body to be identified as the sealing protrusion is fractured in the separation process of the cap body, and may be connected to a lower end of the cap body while extending short from a second end of the cut part to a predetermined range.
- the cut part may be cut long to extend from an uppermost end to a position adjacent to a lowermost end and thereby lead to transformation that causes a restriction force of the connecting projection to be lost by the restraint protrusion formed on the outer circumference of the injection part as the gap is increased by an upward movement of the connecting projection connected to the cap body in the separation process of the cap body, and the cut part may be formed in a slope type having an inclination in one direction.
- the present invention provides a PET container cap with a simultaneously separable end ring, which provides tight blocking for preservation of contents in a state of being provided on and coupled to an injection part and provides a sealing function enabling awareness of openness, the cap including a cap body provided on and coupled to the injection part to provide tight blocking for preservation of the contents; and an end ring integrally formed on a lower side of the cap body, restricted by an annular protrusion protruding from a lower side of an outer circumference of the injection part, exhibiting a sealing function enabling grasping of openness of the cap body, and causing transformation in a separation process of the cap body by a user, so the end ring is separated together with the cap body from the injection part, wherein the end ring may include an interference protrusion restricted by the annular protrusion when the cap body is coupled to the injection part; a plurality of transformation parts transformed to flare out, thus allowing the interference protrusion to pass over the annular protrusion when the cap body is separated from the injection part, due to a
- the interference protrusion may protrude from an inner surface of the transformation part to be restricted by the annular protrusion, may have an inclination in which a protruding end thereof is inclined upwards, and may be bent downwards by the annular protrusion in the process of separating the cap body from the injection part, thus causing the transformation of the transformation part and allowing the interference protrusion to pass over the annular protrusion when the transformation part is transformed.
- the interference protrusion may be in a shape of a simple protrusion that causes the transformation of the transformation part in the process of separating the cap body from the injection part and allows the interference protrusion to pass over the annular protrusion when the transformation part is transformed.
- the present invention provides a PET container cap with a simultaneously separable end ring, which provides tight blocking for preservation of contents in a state of being provided on and coupled to an injection part and provides a sealing function enabling awareness of openness, the cap including a cap body provided on and coupled to the injection part to provide tight blocking for preservation of the contents; an end ring integrally formed on a lower side of the cap body, restricted by an annular protrusion protruding from a lower side of an outer circumference of the injection part, exhibiting a sealing function enabling grasping of openness of the cap body, and causing transformation in a separation process of the cap body by a user, so the end ring is separated together with the cap body from the injection part, the cap body and the end ring being separated from each other by a cut part; a plurality of interference protrusions formed on an inner circumference of a boundary between the cap body and the end ring to protrude at regular intervals, connecting the cap body and the end ring, restricted by the annular protrusion when the
- the interference protrusion may be integrally connected at both ends thereof to the lower end of the cap body and the upper end of the end ring, and may be bent to a side to be restricted by the annular protrusion, thus having a shape of “ ”, and may be spread out by the annular protrusion in the process of separating the cap body from the injection part, so the cap body and the end ring may be separated from each other and thereby the sealing projection may be fractured and interference of the annular protrusion may be avoided to allow the end ring to be simultaneously separated.
- a PET container cap with a simultaneously separable end ring of the present invention allows a cap body as well as an end ring on a lower side of the cap to be simultaneously separated in the process of separating the cap body (cap) from an injection part of a PET container, thus making it possible to recover the PET container as a single material for satisfying recyclability (recycling).

Abstract

The cap includes a cap body which is provided on and coupled to the injection part so as to provide tight blocking for preservation of contents; and an end ring which is integrally formed at the lower side of the cap body, is restricted by an annular protrusion formed at the lower side of the outer circumference of the injection part, exhibits a sealing function enabling grasping of openness of the cap body, and causes transformation in a separation process of the cap body by a user, so that the end ring is simultaneously separated together with the cap body from the injection part.
Description
- The present invention relates to a PET container cap with a simultaneously separable end ring and, more particularly, to a PET container cap with a simultaneously separable end ring, in which when a cap body (a cap) provided on and coupled to an injection part of a PET container is separated, an end ring provided on the lower side of the cap body may be separated therewith.
- Since a polyethylene terephthalate (PET) container which is currently used is especially light, transparent, and recyclable, the PET container has become popular as a container for food and beverage.
- Since the PET container was invented, this was immediately used in the industry due to the boom of a soda drinks and the advantages of the PET material. This container was so booming that 100 billion bottles were produced per year around 1999. At first, this was mostly used as a container for containing liquid such as beverage or sauce. However, recently, the container is used as various package materials for containing alcoholic beverages such as beer or soju as well as eye drops and detergent, so now PET containers have become essential in the living environment of consumers.
- Meanwhile, a cap is provided on an injection part (spout) of the PET container to provide tight blocking for preserving contents (food and beverage, etc.) and a sealing function for identifying openness.
- Specifically, a conventional PET container includes a container body that contains contents, and a cap that is coupled to an injection part of the container body. A spiral binding protrusion for fastening the cap and an annular protrusion for preventing the separation of the cap are formed on an outer circumference of the injection part of the container body.
- Further, the cap includes a cap body that seals and tightly blocks the injection part of the container body and an end ring that seals the cap body. A spiral protrusion is formed on the inner circumference of the cap body to correspond to a binding protrusion formed on the outer circumference of the injection part, and a plurality of interference protrusions is formed on the inner circumference of the end ring to engage with the annular protrusion formed on the outer circumference of the injection part.
- Therefore, even if the cap is rotated counterclockwise to be separated from the injection part of the PET container, the interference protrusion on the inner circumference of the end ring engages with the annular protrusion on the outer circumference of the injection part to be thereby constrained. Consequently, the end ring remains in the PET container.
- In this regard, the PET container and the cap are made of different materials, i.e., PET and PE (high density polyethylene; HDPE). In order to satisfy the recyclability (recycling) of the PET container, it is preferable to separate different materials, i.e., the cap and the end ring that is the accessory of the cap and then recover a single material if possible.
- To this end, the end ring is separated from the PET container in the method of cutting the end ring using a cutting tool such as scissors or nippers. However, because of the inconvenience of this method, the PET container is usually recovered with the end ring remaining. This makes separate garbage collection difficult, so the PET container is thrown away as general waste, thus wasting resources as well as causing environmental pollution.
- In order to solve the problem, Korean Patent Laid-Open Publication No. 10-2012-0101626 has disclosed a structure for removing an end ring of a resin bottle cap and a container having the same. The conventional structure for removing the end ring of the resin bottle cap and the container having the same are configured such that a portion of a ring stop upper flange (annular protrusion) for restricting the end ring on an injection part is cut in the shape of a slope to form a guide flange cut part. Thus, if the end ring is rotated, a plurality of protruding flaps (interference protrusions) formed on the inner circumference of the end ring leaves the guide flange cut part, thus allowing the end ring to be easily removed from the injection part.
- However, since the guide flange cut part should be necessarily formed to achieve the above-described structure for removing the end ring, there is a problem of lack of compatibility that the injection part of the PET container should be manufactured in a shape different from the conventional injection part, which makes it somewhat difficult to apply in practice.
- Eventually, in the process of separating the cap from the PET container without changing the shape of the PET container, research and development for the PET container cap in which the end ring can be separated (removed) together are required.
- The present invention has been made to solve the above-mentioned problems and difficulties and relates to a PET container cap with a simultaneously separable end ring, in which the end ring on the lower side of a cap body is transformed in the process of separating the cap body (cap) from an injection part of a PET container, so the restriction force of the end ring (interference protrusion formed on an inner circumference) by an annular protrusion protruding from the outer circumference of the injection part is lost when the cap body is separated, and thus the end ring can also be separated (removed).
- In order to accomplish the above objective, the present invention provides a PET container cap with a simultaneously separable end ring, which provides tight blocking for preservation of contents in a state of being provided on and coupled to an injection part and provides a sealing function enabling awareness of openness, the cap including a cap body provided on and coupled to the injection part to provide tight blocking for preservation of the contents; and an end ring integrally formed on a lower side of the cap body, restricted by an annular protrusion formed on a lower side of an outer circumference of the injection part, exhibiting a sealing function enabling grasping of openness of the cap body, and causing transformation in a separation process of the cap body by a user, so the end ring is simultaneously separated together with the cap body from the injection part.
- The cap body may further include a spiral protrusion formed on an inner circumference of the cap body to correspond to a spiral fastening protrusion formed on the outer circumference of the injection part; and a knurling part formed on an outer circumference of the cap body to prevent a slip when a user holds the cap with his or her hand and rotates the cap clockwise/counterclockwise.
- The end ring may include an interference protrusion formed on an inner circumference of the end ring to engage with a restraint protrusion of the injection part when the cap body is coupled to the injection part; a connecting projection integrally connected to a portion of a lower end of the cap body to cause transformation in a separation process of the cap body; and a sealing projection integrally connected to another portion of the lower end of the cap body to be fractured in the separation process of the cap body and to enable the openness of the cap body to be identified.
- The end ring may include a plurality of cut parts that are cut long to extend from an uppermost end to a lowermost end, are inclined in one direction, and are formed at regular intervals to cause degradation of a ring-shaped preservation ability as a gap is increased by the connecting projection that maintains a connection state with the cap body in the separation process of the cap body.
- The connecting projection may be connected to the cap body to increase the gap of the cut part in the separation process of the cap body, may protrude from an upper end, and may be connected to the lower end of the cap body while extending long from a first end of the cut part to a predetermined range, and the sealing projection may be connected to the cap body, may protrude from an upper end to exhibit the sealing function that enables the openness of the cap body to be identified as the sealing protrusion is fractured in the separation process of the cap body, and may be connected to a lower end of the cap body while extending short from a second end of the cut part to a predetermined range.
- The cut part may be cut long to extend from an uppermost end to a position adjacent to a lowermost end and thereby lead to transformation that causes a restriction force of the connecting projection to be lost by the restraint protrusion formed on the outer circumference of the injection part as the gap is increased by an upward movement of the connecting projection connected to the cap body in the separation process of the cap body, and the cut part may be formed in a slope type having an inclination in one direction.
- The present invention provides a PET container cap with a simultaneously separable end ring, which provides tight blocking for preservation of contents in a state of being provided on and coupled to an injection part and provides a sealing function enabling awareness of openness, the cap including a cap body provided on and coupled to the injection part to provide tight blocking for preservation of the contents; and an end ring integrally formed on a lower side of the cap body, restricted by an annular protrusion protruding from a lower side of an outer circumference of the injection part, exhibiting a sealing function enabling grasping of openness of the cap body, and causing transformation in a separation process of the cap body by a user, so the end ring is separated together with the cap body from the injection part, wherein the end ring may include an interference protrusion restricted by the annular protrusion when the cap body is coupled to the injection part; a plurality of transformation parts transformed to flare out, thus allowing the interference protrusion to pass over the annular protrusion when the cap body is separated from the injection part, due to a “”-shaped cut part extending horizontally and vertically from a boundary of the cap body; and a sealing projection protruding from an upper end of each of the transformation parts to be integrally connected to a lower end of the cap body, fractured in the separation process of the cap body, and enabling the openness of the cap body to be identified depending on a fractured state.
- The interference protrusion may protrude from an inner surface of the transformation part to be restricted by the annular protrusion, may have an inclination in which a protruding end thereof is inclined upwards, and may be bent downwards by the annular protrusion in the process of separating the cap body from the injection part, thus causing the transformation of the transformation part and allowing the interference protrusion to pass over the annular protrusion when the transformation part is transformed.
- The interference protrusion may be in a shape of a simple protrusion that causes the transformation of the transformation part in the process of separating the cap body from the injection part and allows the interference protrusion to pass over the annular protrusion when the transformation part is transformed.
- The present invention provides a PET container cap with a simultaneously separable end ring, which provides tight blocking for preservation of contents in a state of being provided on and coupled to an injection part and provides a sealing function enabling awareness of openness, the cap including a cap body provided on and coupled to the injection part to provide tight blocking for preservation of the contents; an end ring integrally formed on a lower side of the cap body, restricted by an annular protrusion protruding from a lower side of an outer circumference of the injection part, exhibiting a sealing function enabling grasping of openness of the cap body, and causing transformation in a separation process of the cap body by a user, so the end ring is separated together with the cap body from the injection part, the cap body and the end ring being separated from each other by a cut part; a plurality of interference protrusions formed on an inner circumference of a boundary between the cap body and the end ring to protrude at regular intervals, connecting the cap body and the end ring, restricted by the annular protrusion when the cap body is coupled to the injection part, and changed in shape to pass over the annular protrusion in the process of separating the cap body; and a sealing projection formed on the inner circumference of the boundary, connecting a lower end of the cap body and an upper end of the end ring, fractured in the separation process of the cap body, and enabling the openness of the cap body to be identified depending on the fractured state.
- The interference protrusion may be integrally connected at both ends thereof to the lower end of the cap body and the upper end of the end ring, and may be bent to a side to be restricted by the annular protrusion, thus having a shape of “”, and may be spread out by the annular protrusion in the process of separating the cap body from the injection part, so the cap body and the end ring may be separated from each other and thereby the sealing projection may be fractured and interference of the annular protrusion may be avoided to allow the end ring to be simultaneously separated.
- As described above, a PET container cap with a simultaneously separable end ring of the present invention allows a cap body as well as an end ring on a lower side of the cap to be simultaneously separated in the process of separating the cap body (cap) from an injection part of a PET container, thus making it possible to recover the PET container as a single material for satisfying recyclability (recycling).
- In particular, as described above, when a cap body is rotated counterclockwise to be separated from an injection part of a PET container, this leads to the transformation (degradation of the preservation ability of a ring shape) of an end ring, thereby allowing an interference protrusion formed on the inner circumference of the end ring to disengage from an annular protrusion formed on the outer circumference of the injection part. Consequently, it is possible to more easily separate the end ring from the injection part.
- Furthermore, the above-described effects do not only facilitate separating an end ring, but also serve as a guideline for developing competitive products, thus enhancing the quality of life. Therefore, this is a very useful invention that can greatly contribute to the establishment of a policy and recovery technology for a waste-resource recycling industry that recovers and recycles resources from discarded waste resources.

FIGS. 1 to 3 , the PET container cap A with the simultaneously separable end ring in accordance with the first embodiment of the present invention includes acap body 1 that is provided on and coupled to an injection part of the PET container to preserve contents, and anend ring 2 that is integrally formed on the lower side of thecap body 1, is restricted by an annular protrusion formed on the lower side of the outer circumference of the injection part, has a sealing function for identifying the openness of thecap body 1, and causes transformation in a separation process of thecap body 1 by a user, so theend ring 2 is simultaneously separated together with thecap body 1 from the injection part of the PET container. - The
cap body 1 is provided on and coupled to the injection part of the PET container for the purpose of preservation so as to prevent the leakage of contents (food and beverage, etc.) contained in the PET container, and abinding protrusion 11 is formed on the inner circumference of the cap body to correspond to a spiral binding protrusion formed on the outer circumference of the injection part of the PET container. - Preferably, a
knurling part 12 is further formed on the outer circumference of thecap body 1 to prevent a slip when a user holds the cap with his or her hand and rotates the cap clockwise/counterclockwise. - The
end ring 2 exhibits the sealing function of thecap body 1 that is provided on and coupled to the injection part of the PET container. As shown inFIGS. 4 and 5 , aninterference protrusion 21 is formed on the inner circumference of the end ring to engage with anannular protrusion 920 formed on the outer circumference of aninjection part 910 when thecap body 1 is coupled to theinjection part 910 of thePET container 900. - Further, a connecting
projection 22 and a sealingprojection 23 are formed on the end ring. The connecting projection is integrally connected to a portion of a lower end of thecap body 1 to cause the transformation in the separation process of thecap body 1. The sealingprojection 23 is integrally connected to another portion of the lower end of thecap body 1 to be fractured in the separation process of thecap body 1 and identify the openness of thecap body 1. - In addition, a plurality of

projection 23 is connected to thecap body 1, exhibits the sealing function to allow a user to identify the openness of thecap body 1 as the sealing protrusion is fractured in the separation process of thecap body 1, protrudes from the upper end, and is connected to the lower end of thecap body 1 while extending short from a second end of thecut part 24 to a predetermined range. - The
cut part 24 leads to transformation (degradation of the ring-shaped preservation ability) to cause the restriction force of the connectingprojection 22 to be lost by theannular protrusion 920 formed on the outer circumference of theinjection part 910 as the gap is increased by the upward movement of the connectingprojection 22 connected to thecap body 1 in the separation process of thecap body 1. The cut part is cut long to extend from the uppermost end to a position adjacent to the lowermost end, and is preferably formed in a slope type having an inclination in one direction. - Meanwhile,
FIGS. 6 to 8 are a perspective view and a sectional view illustrating the configuration of a PET container cap with a simultaneously separable end ring in accordance with a second embodiment of the present invention,FIG. 9 is a perspective view illustrating important parts of the configuration of the end ring of the PET container cap with the simultaneously separable end ring in accordance with the second embodiment of the present invention, and FIG. is a sectional view illustrating the use of the PET container cap with the simultaneously separable end ring in accordance with the second embodiment of the present invention. As shown inFIGS. 6 to 8 , a PET container cap A-1 with a simultaneously separable end ring in accordance with the second embodiment of the present invention includes acap body 1 that is provided on and coupled to aninjection part 910 of thePET container 900 to preserve contents, and anend ring 2 that is integrally formed on the lower side of thecap body 1, is restricted by anannular protrusion 920 formed on the lower side of the outer circumference of theinjection part 910, has a sealing function for identifying the openness of thecap body 1, and causes transformation in a separation process of thecap body 1 by a user, so the end ring is separated together with thecap body 1 from theinjection part 910 of thePET container 900. - The
cap body 1 is coupled to theinjection part 910 of thePET container 900 to prevent the leakage of the contents contained in thePET container 900, and the bindingprotrusion 11 is formed on the inner circumference of the cap body to correspond to abinding protrusion 930 protruding spirally from the outer circumference of theinjection part 910 of thePET container 900. - Preferably, as shown in
FIG. 8 , the bindingprotrusion 11 is formed on the inner circumference of thecap body 1, and theknurling part 12 is formed on the outer circumference thereof. - The
end ring 2 is intended to realize the sealing function of thecap body 1 that is coupled to theinjection part 910 of thePET container 900. As shown inFIGS. 8 and 9 , the end ring includes an interference protrusion 21-1 that is restricted by theannular protrusion 920 protruding from the outer circumference of theinjection part 910 when thecap body 1 is coupled to theinjection part 910, and a plurality oftransformation parts 25 that are transformed to flare out, thus allowing the interference protrusion 21-1 to pass over theannular protrusion 920 when thecap body 1 is separated from thePET container 900 due to the cut part 24-1. - Further, a sealing projection 23-1 protrudes from the upper end of the
transformation part 25 to be integrally connected to the lower end of thecap body 1, is fractured in the separation process of thecap body 1, and enables the openness of thecap body 1 to be identified depending on the fractured state. - The interference protrusion 21-1 has an inclination in which an end thereof protrudes upwards from the inner surface of the
transformation part 25, so the interference protrusion may be restricted by theannular protrusion 920 protruding from the outer circumference of theinjection part 910 of thePET container 900. In the process of separating thecap body 1 from theinjection part 910, the interference protrusion is bent downwards by theannular protrusion 920, thus causing the transformation of thetransformation part 25 and allowing the interference protrusion to pass over theannular protrusion 920 when thetransformation part 25 is transformed. -
- Further,
FIG. 11 is a sectional view illustrating another configuration of an interference protrusion, in the PET container cap with the simultaneously separable end ring in accordance with the second embodiment of the present invention. In the PET container cap with the simultaneously separable end ring in accordance with the second embodiment, as shown inFIG. 11 , the interference protrusion 21-2 of another configuration may be in the shape of a simple protrusion that causes the transformation of thetransformation part 25 in the process of separating thecap body 1 and allows the interference protrusion to pass over theannular protrusion 920 when the transformation part is transformed. - On the other hand,
FIG. 12 is a sectional view illustrating the configuration of a PET container cap with a simultaneously separable end ring in accordance with a third embodiment of the present invention. As shown inFIG. 12 , the PET container cap A-2 with the simultaneously separable end ring in accordance with the third embodiment of the present invention includes acap body 1 that is provided on and coupled to aninjection part 910 of thePET container 900 to preserve contents, and anend ring 2 that is integrally formed on the lower side of thecap body 1, is restricted by anannular protrusion 920 formed on the lower side of the outer circumference of theinjection part 910, has a sealing function for identifying the openness of thecap body 1, and causes transformation in the separation process of thecap body 1 by a user, so the end ring is separated together with thecap body 1 from theinjection part 910 of thePET container 900. Thecap body 1 and theend ring 2 are separated from each other by a cut part 24-2. - Preferably, as shown in
FIG. 12 , the bindingprotrusion 11 is formed on the inner circumference of thecap body 1, and theknurling part 12 is formed on the outer circumference thereof. - Further, a plurality of interference protrusions 21-3 and a sealing projection 23-2 are formed on an inner circumference of a boundary between the
cap body 1 and theend ring 2 separated to each other by the cut part 24-2. The interference protrusions protruding at regular intervals connect the cap body and the end ring, are restricted by theannular protrusion 920 protruding from the outer circumference of theinjection part 910 when thecap body 1 is coupled to theinjection part 910 of thePET container 900, and are changed in shape to pass over theannular protrusion 920 in the process of separating thecap body 1 from thePET container 900. The sealing projection connects the lower end of thecap body 1 and the upper end of theend ring 2, is fractured in the separation process of thecap body 1, and enables the openness of thecap body 1 to be identified depending on the fractured state. - The interference protrusion 21-3 is integrally connected at both ends thereof to the lower end of the
cap body 1 and the upper end of theend ring 2, and is bent to a side to be restricted by theannular protrusion 920 protruding from the outer circumference of theinjection part 910 of thePET container 900, thus having the shape of “”. In the process of separating thecap body 1 from theinjection part 910, thecap body 1 and theend ring 2 are separated from each other by theannular protrusion 920, so the sealing projection 23-2 is fractured and the interference of theannular protrusion 920 may be avoided to allow theend ring 2 to be simultaneously separated. - The operation of the PET container cap A with the simultaneously separable end ring according to the present invention configured as such will be described in detail. The operation of the cap A with the simultaneously separable end ring according to the first embodiment of the present invention is as follows.
-
FIGS. 13 to 15 are diagrams illustrating the operation of the PET container cap with the simultaneously separable end ring in accordance with the first embodiment of the present invention, andFIGS. 16 and 17 are sectional views illustrating the transformation of the end ring when the PET container cap with the simultaneously separable end ring in accordance with the first embodiment of the present invention is separated. As shown inFIG. 13 , the PET container cap A with the simultaneously separable end ring in accordance with the first embodiment of the present invention is coupled to theinjection part 910 of thePET container 900, thus sealing and tightly blocking theinjection part 910 to preserve contents (food and beverage, etc.) contained in thePET container 900, and providing the sealing function to enable the openness to be identified. - In this state, the cap A is separated from the
injection part 910, so a user may drink the contents contained in thePET container 900. As described above, in the separation process of the cap A, theend ring 2 connected to the lower side of thecap body 1 is separated together with thecap body 1, so the end ring can be easily removed from thePET container 900. - In other words, the
cap body 1 coupled to theinjection part 910 of thePET container 900 is rotated counterclockwise, so thecap body 1 moves upwards along theinjection part 910. By continuing this process, the cap body is completely separated from thePET container 900, thus opening theinjection part 910. Thereby, a user may drink beverage contained in thePET container 900. - In such a process, the
end ring 2 integrally provided on the lower side of thecap body 1 is separated (removed) from theinjection part 910 together with thecap body 1, so it is possible to recover thePET container 900 of a single material, thus greatly enhancing recyclability. - Specifically, if the
cap body 1 coupled to theinjection part 910 is rotated counterclockwise to open theinjection part 910, the bindingprotrusion 11 formed on the inner circumference of thecap body 1 moves along thebinding protrusion 930 formed on the outer circumference of theinjection part 910 of thePET container 900, so thecap body 1 moves to the upper side of theinjection part 910. By continuing this process, the cap body is completely separated from theinjection part 910 of thePET container 900. - In this regard, as the interference protrusion formed on the inner circumference of the
end ring 2 engages with theannular protrusion 920 formed on the outer circumference of the injection part 910 (seeFIG. 16 ), as shown inFIG. 17 , a gap between thecap body 1 and theend ring 2 increases. In such a process, the sealingprojection 23 formed on the upper end of theend ring 2 and connected to the lower end of thecap body 1 is fractured by tension. Further, a portion of theend ring 2 on which the connectingprojection 22 is formed is lifted upwards about thecut part 24 by the connectingprojection 22 formed on another upper end of theend ring 2 and connected to another lower end of thecap body 1, thus causing transformation in which the gap of thecut part 24 increases. Due to the loss of the shape preservation ability (degradation of the ring-shaped preservation ability) caused by the transformation of theend ring 2, as shown inFIG. 17 , theinterference protrusion 21 on the inner circumference of theend ring 2 passes over theannular protrusion 920 on the outer circumference of theinjection part 910 of thePET container 900. Thus, as shown inFIG. 15 , theend ring 2 completely escapes from theinjection part 910 and theend ring 2 as well as thecap body 1 may be simultaneously separated from thePET container 900. - Therefore, it is possible to separate both the
cap body 1 and theend ring 22 that is the accessory of thecap body 1, thus recovering thePET container 900 of a single material and thereby maximizing recyclability (seeFIG. 15 ). - Further,
FIGS. 18 to 20 are sectional views illustrating the operation of the PET container cap with the simultaneously separable end ring in accordance with the second embodiment of the present invention. The operation of the cap A-1 with the simultaneously separable end ring in accordance with the second embodiment of the present invention is as follows. - As shown in
FIGS. 18 to 20 , the PET container cap A-1 with the simultaneously separable end ring in accordance with the second embodiment of the present invention is coupled to theinjection part 910 of the PET container 900 (seeFIG. 10 ), thus sealing and tightly blocking theinjection part 910 to preserve contents (food and beverage, etc.) contained in thePET container 900, and providing the sealing function to enable the openness to be identified. - In this state, the cap A-1 is separated from the
injection part 910, so a user may drink the contents contained in thePET container 900. As described above, in the separation process of the cap A-1, theend ring 2 connected to the lower side of thecap body 1 is separated together with thecap body 1, so the end ring can be easily removed from thePET container 900. - In other words, the
cap body 1 coupled to theinjection part 910 of thePET container 900 is rotated counterclockwise, so thecap body 1 moves upwards along theinjection part 910. By continuing the process (rotation), the cap body is completely separated from thePET container 900, thus opening theinjection part 910. Thereby, a user may drink beverage contained in thePET container 900. - In such a process, the
end ring 2 integrally provided on the lower side of thecap body 1 is separated (removed) from theinjection part 910 together with thecap body 1, so it is possible to recover thePET container 900 of a single material, thus greatly enhancing recyclability. - Specifically, if the
cap body 1 coupled to theinjection part 910 is rotated counterclockwise to open theinjection part 910, the bindingprotrusion 11 formed on the inner circumference of thecap body 1 moves along thebinding protrusion 930 formed on the outer circumference of theinjection part 910 of thePET container 900, so thecap body 1 moves to the upper side of theinjection part 910. By continuing this process, the cap body is completely separated from theinjection part 910 of thePET container 900. - That is, as shown in
FIG. 18 , the protruding end of the interference protrusion 21-1 of theend ring 2 restricted by theannular protrusion 920 protruding from the outer circumference of theinjection part 910 is bent downwards by the interference of theannular protrusion 920. Thus, due to the loss of the shape preservation ability (degradation of the ring-shaped preservation ability) caused by transformation in which thetransformation part 25 flares out as the protruding end of the interference protrusion 21-1 is bent downwards, as shown inFIG. 19 , the sealing projection 23-1 formed on the upper end of theend ring 2 and connected to the lower end of thecap body 1 is fractured by tension. Further, as the interference protrusion 21-1 is completely bent downwards with the continued process, as shown inFIG. 19 , the interference protrusion 21-1 on the inner circumference of theend ring 2 may pass over theannular protrusion 920 protruding from the outer circumference of theinjection part 910 of thePET container 900. Thus, as shown inFIG. 20 , theend ring 2 may be simultaneously separated from theinjection part 910 of thePET container 900 along thecap body 1. - Therefore, it is possible to separate both the
cap body 1 and theend ring 22 that is the accessory of thecap body 1, thus recovering thePET container 900 of a single material and thereby maximizing recyclability. - Further,
FIGS. 21 to 24 are sectional views illustrating the operation of the PET container cap with the simultaneously separable end ring in accordance with the third embodiment of the present invention. The operation of the cap A-2 with the simultaneously separable end ring in accordance with the third embodiment of the present invention is as follows. - If the
cap body 1 of the cap A-2 coupled to theinjection part 910 is rotated counterclockwise to open theinjection part 910 as shown inFIGS. 21 and 22 , the interference protrusion 21-3 of theend ring 2 restricted by theannular protrusion 920 protruding from the outer circumference of theinjection part 910 is completely spread out by the interference of theannular protrusion 920 as shown inFIG. 23 . Thus, thecap body 1 and theend ring 2 are separated from each other, so the sealing projection 23-1 formed on the upper end of theend ring 2 and connected to the lower end of thecap body 1 is fractured by tension. Further, the interference protrusion 21-3 may pass over theannular protrusion 920 protruding from the outer circumference of theinjection part 910 of thePET container 900. Thus, as shown inFIG. 24 , theend ring 2 may be simultaneously separated from theinjection part 910 of thePET container 900 along thecap body 1. - In conclusion, the PET container cap A, A-1, or A-2 with the simultaneously separable end ring according to the present invention is configured such that the
end ring 2 as well as thecap body 1 can be simultaneously separated in the process of separating thecap body 1 from theinjection part 910 of thePET container 900, thus enabling thePET container 900 to be recovered as a single material for satisfying recyclability (recycling). - In particular, as described above, when the
cap body 1 is rotated counterclockwise to be separated from theinjection part 910 of thePET container 900, this increases the gap of thecut part 24 and leads to the transformation (degradation of the preservation ability of the ring shape) of theend ring 2, thereby allowing theinterference protrusion 21, 21-1, 21-2, or 21-3 to disengage from theannular protrusion 920 formed on the outer circumference of theinjection part 910. Consequently, it is possible to more easily separate theend ring 2 from theinjection part 910. - While the present invention has been particularly described with reference to exemplary embodiments shown in the drawings, it will be understood by those of ordinary skill in the art that the exemplary embodiments have been described for illustrative purposes, and various changes and modifications may be made without departing from the spirit and scope of the present invention as defined by the appended claims. Accordingly, embodiments of the present invention are intended not to limit the technical idea of the invention but to illustrate the technical idea. The scope of the present invention is not limited to the embodiments. It is to be understood that the scope of the present invention is defined solely by the following claims and equivalences thereof.
- In a waste-resource recycling industry that recovers and recycles resources from discarded waste resources, a cap body as well as an end ring on the lower side of the cap can be simultaneously separated in the process of separating the cap body (cap) from an injection part of the PET container, so it is possible to recover the PET container as a single material for satisfying recyclability.
