본 발명은 페트(PET)병의 본체에 굴곡진 접이면과 접이주름을 형성하여 접을 수 있는 구조로 제작함으로써, 내부에 담겨 있는 음료수를 마신 후에 빈 페트병의 용적을 축소시키는 것이 가능하여 수거시에 편리하도록 부피를 줄일 수 있고, 다시 원상태로 복원하여 재사용할 수 있는 용적변형 페트병에 관한 것이다.The present invention forms a folded folding surface and a fold wrinkle on the body of the PET bottle to produce a foldable structure, it is possible to reduce the volume of the empty PET bottle after drinking the beverage contained therein at the time of collection The present invention relates to a volumetric PET bottle which can be reduced in volume for convenience and can be recovered and reused.

일반적으로 페트병은 수지제로 제조되고 주로 생수 또는 탄산음료수를 비롯하여 각종 음료수가 담겨져 판매되고 있으며, 이러한 페트병의 장점은 재질이 수지제로 제조됨으로써 가볍고 저렴하게 공급될 수 있으며 취급시 유리병처럼 깨지지 않는 장점이 있어서 널리 활용되고 있다.In general, PET bottles are made of resin and are mainly sold in a variety of beverages including bottled water or carbonated beverages.The advantage of these bottles is that the material is made of resin, so it can be supplied lightly and inexpensively, and it does not break like a glass bottle when handling. It is widely used.

하지만 페트병은 사용 후에도 여전히 부피가 커서 수거시에 불편하다는 단점이 있으며, 이를 보완하기 위하여 본 출원인은 특허출원 제2004-16452호에서 접이주름을 구비한 용적축형식 변형용기를 개시한 바 있다.However, the PET bottle has a disadvantage in that it is still inconvenient at the time of collection due to its large volume, and to compensate for this, the applicant has disclosed a volumetric shaft-shaped deformation container having a folded wrinkle in Patent Application No. 2004-16452.

그러나, 이러한 용적축형식 변형용기의 단수주름은 정사각형으로 형성되어 있어 접이면 역시 정사각형의 평면으로 형성되므로 굴곡이 없는 접이면을 가진 용기를 접을 때에 비트는 힘이 압축력으로 제대로 전달되지 않아서 초기에 원활하게 접히지 않는다. 또한, 공기를 주입하여 금형의 형상으로 페트병을 제조하는 과정에서도 정사각형 구조는 원형에 가까운 정팔각형 구조보다 생산성이 훨씬 떨어지는 문제점이 있었다.However, since the singular wrinkle of the volumetric deformation container is formed in a square shape, when folded, it is also formed in the plane of the square, and thus, when the container having a folding surface without bending is folded, the twisting force is not properly transmitted by the compressive force. Does not fold. In addition, even in the process of manufacturing a PET bottle in the shape of a mold by injecting air, the square structure has a problem that the productivity is much lower than the square octagonal structure close to the circular shape.

전술한 문제점을 해결하기 위한 본 발명의 목적은, 페트병의 본체에 정팔각형의 단수주름을 형성하고 단수주름 사이의 굴곡진 접이면에 접이주름을 형성하여 용이하게 접히는 구조로 제작함으로써, 내부에 담겨 있는 음료수를 마신 후에 빈 페트병의 용적을 축소하는 것이 가능하여 수거시의 부피를 줄일 수 있고, 다시 원 상태로 복원하여 재사용할 수 있는 용적변형 페트병에 관한 기술을 제공함에 있다.An object of the present invention for solving the above-mentioned problems, by forming a octagonal singular wrinkles on the body of the PET bottle and by forming a fold wrinkles on the curved folding surface between the singular wrinkles to be easily folded structure, so that the inside It is possible to reduce the volume of an empty PET bottle after drinking a beverage, to reduce the volume of the collection, and to provide a technique regarding a volumetric PET bottle that can be restored to its original state and reused.

본 발명의 또 다른 목적은 접이주름에 형성되는 만곡부과 접이홈의 수치를 한정하여 접히는 효과가 극대화되면서 생산성도 크게 향상된 용적변형 페트병에 관한 기술을 제공함에 있다.Still another object of the present invention is to provide a technique for a volumetric PET bottle, in which the productivity is also greatly improved while maximizing the folding effect by limiting the numerical values of the curved portions and the folding grooves formed on the folding wrinkles.

이하, 본 발명의 바람직한 실시예를 첨부된 도면들을 참조하여 상세히 설명한다. 본 발명을 설명함에 있어, 관련된 공지 구성 또는 기능에 대한 구체적인 설명이 본 발명의 요지를 흐릴 수 있다고 판단되는 경우에는 그 상세한 설명은 생략한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

본 발명의 바람직한 실시예에 따른 용적변형 페트병은 도 1 및 도 2에 도시한 바와 같이, 본체(1)와 마개부(2)로 이루어진 페트병에 있어서, 본체(1)에는 상하로 일정한 간격을 두고 형성된 적어도 3개의 정팔각형 단수주름(10); 단수주름(10) 사이에 형성되며 단수주름(10)의 2개씩의 변을 상변과 하변으로 포함하는 4개의 굴곡진 접이면(20)이 적어도 상하 2층으로 형성되고, 접이면(20)에는 제1모서리(21)와 제3모서리(23)를 연결하고 제2모서리(22)와 제4모서리(24)를 연결하여 형성된 "X"자형의 접이주름(30); 접이면(20)에는 중심점(27)과 제5모서리(25)를 연결하고 중심점(27)과 제6모서리(26)를 연결하여 형성된 2개의 접이보조선(28); 및 접이주름(30)에는 직선(31)보다 최대 0.9 ~ 1.5mm 아래로 굽은 만곡부(32)가 형성되고, 만곡부(32)보다 최대 0.9 ~ 1.5mm 아래로 파인 접이홈(33)을 포함하고, 본 체(1)의 상부와 하부를 서로 반대방향으로 회전시켜 용적을 줄일 수 있는 것을 특징으로 한다.1 and 2, the volumetric plastic bottle according to the preferred embodiment of the present invention, in the PET bottle consisting of the main body 1 and the stopper (2), the main body 1 at regular intervals up and down At least three regular octagonal singular wrinkles 10 formed; Four curved folding surfaces 20 formed between the singular wrinkles 10 and including two sides of the singular wrinkles 10 as the upper and lower sides are formed in at least two upper and lower layers. A fold wrinkle having an “X” shape formed by connecting the first edge 21 and the third edge 23 and connecting the second edge 22 and the fourth edge 24; Two folding auxiliary lines 28 formed by connecting the center point 27 and the fifth corner 25 and connecting the center point 27 and the sixth corner 26 to the folding surface 20; And the fold wrinkle 30 is formed with a curved portion 32 is bent up to 0.9 ~ 1.5mm lower than the straight line 31, and includes a folding groove 33 which is dug up to 0.9 ~ 1.5mm below the curved portion 32, It is characterized in that the volume can be reduced by rotating the upper and lower portions of the body 1 in opposite directions.

페트병의 본체(1)에는 3개의 정팔각형 단수주름(10)이 상하로 일정한 간격을 두고 형성되고, 각각의 단수주름(10) 사이에는 둘레로 4개의 접이면(20)이 형성되어 모두 8개의 접이면(20)이 형성된다. 이때, 접이면(20)은 정팔각형 단수주름(10)에서 상하 2개씩의 변을 상변과 하변으로 포함하므로 당연히 굴곡지게 된다.Three main octagonal single wrinkles 10 are formed at regular intervals up and down in the main body 1 of the PET bottle, and four folding surfaces 20 are formed around each of the single wrinkles 10 to form all eight If folded 20 is formed. At this time, the folding surface 20 is naturally curved because it includes the upper and lower sides of each of the upper and lower sides in the octagonal singular wrinkle (10).

또한, 굴곡진 접이면(20)에는 제1모서리(21)와 제3모서리(23)가 연결되고 제2모서리(22)와 제4모서리(24)가 연결되어 "X"자형의 접이주름(30)이 형성되며, "X"자형의 접이주름(30)의 교차점인 중심점(27)과 제5모서리(25)가 연결되고 중심점(27)과 제6모서리(26)가 연결되어 상하로 2개의 접이보조선(28)이 형성된다.In addition, the first folding edge 21 and the third edge 23 is connected to the curved folding surface 20, and the second edge 22 and the fourth edge 24 are connected to each other to form an “X” -shaped folding wrinkle ( 30) is formed, and the center point 27 and the fifth corner 25, which are the intersection points of the “X” -shaped folding wrinkles 30, are connected, and the center point 27 and the sixth corner 26 are connected to each other up and down. Two fold lines 28 are formed.

따라서 도 1 및 도2에 도시된 바와 같이 정팔각형 단수주름(10)으로 인해 접이면(20)에 형성된 접이보조선(28) 부근이 돌출되어 있으므로 접이면(20)은 평면이 아니라 굴곡지게 되고, 이와 같은 굴곡진 접이면(20)이 페트병을 더욱 원활하게 접을 수 있도록 도와주게 된다.Therefore, as shown in FIGS. 1 and 2, because the octagonal singular wrinkles 10 protrude from the vicinity of the fold line 28 formed on the folding surface 20, the folding surface 20 is curved rather than flat. , If the curved folding 20 will help to fold the PET bottle more smoothly.

한편, 접히는 효과를 더욱 향상시키기 위하여 접이주름(30)에는 제1모서리(21)와 제3모서리(23) 그리고 제2모서리(22)와 제4모서리(24)를 연결하는 각각의 직선(31)보다 최대 0.9 ~ 1.5mm 아래로 굽은 만곡부(32)를 형성하고, 만곡부(32)보다 최대 0.9 ~ 1.5mm 아래로 파인 접이홈(33)을 형성하는 것이 바람직하다.Meanwhile, in order to further improve the folding effect, each of the straight lines 31 connecting the first edge 21, the third edge 23, and the second edge 22 and the fourth edge 24 to the folding wrinkles 30. It is preferable to form the curved portion 32 that is bent up to 0.9 to 1.5 mm below the maximum, and to form the folding groove 33 that is not more than 0.9 to 1.5 mm below the curved portion 32.

이때, 아래로 굽은 만곡부(32)가 최대 0.9 ~ 1.5mm를 벗어나게 되면 접히는 효과에 도움이 되지 않거나 오히려 방해가 되고, 만곡부(32) 아래로 파인 접이 홈(33)이 최대 0.9 ~ 1.5mm를 벗어나게 되면 페트병 제조과정에 문제가 발생하거나 접히는 효과가 현저하게 감소하게 된다.At this time, if the curved portion bent downward 32 is out of the maximum 0.9 ~ 1.5mm does not help or hinder the folding effect, the folding groove 33 is dug under the curved portion 32 is out of the maximum 0.9 ~ 1.5mm If the problem occurs during the PET bottle manufacturing process or folding effect is significantly reduced.

이와 같이 구성된 본 발명의 바람직한 실시예에 따른 용적변형 페트병의 기능 및 작용을 도 3을 참조하여 설명하면 다음과 같다.The function and action of the volumetric plastic bottle according to the preferred embodiment of the present invention configured as described above will be described with reference to FIG. 3.

사용자가 본 발명에 따른 용적변형 페트병에 담겨져 있는 음료수를 다 마시고 재활용 쓰레기통에 버리기 전에 본체(1)의 상부를 반시계 방향으로, 하부를 시계방향으로 회전시키게 되면, 비트는 힘(torsion)에 의해 제1모서리(21)와 제3모서리(23)에는 압축력이 작용하게 된다. 이때, 정팔각형 단수주름(10)으로 인해 접이보조선(28) 부근이 돌출되어 있으므로 돌출된 부분이 비트는 힘을 제1모서리(21)와 제3모서리(23)에 압축력으로 변환하여 효과적으로 전달하게 되고, "X"자형의 접이주름(30)이 접이면(20)에서 접이보조선(28)보다 낮게 형성되므로 제2모서리(22)와 제4모서리(24) 사이에 형성된 접이주름(30)이 원활하게 접히게 된다.If the user rotates the upper part of the main body 1 in the counterclockwise direction and the lower part in the clockwise direction before the user drinks all the beverage contained in the volumetric plastic bottle according to the present invention and throws it into the recycling bin, the torsion force Compression force acts on the first corner 21 and the third corner 23. At this time, since the fold line 28 is protruded due to the regular octagonal number of wrinkles 10, the protruding portion is effectively converted into a compressive force to the first edge 21 and the third edge 23 to be effectively transmitted. If the "X" -shaped folding wrinkles 30 are formed to be lower than the folding auxiliary line 28 at the folding 20, the folding wrinkles 30 formed between the second edge 22 and the fourth edge 24 are formed. ) Will fold smoothly.

한편, 굴곡진 접이면(20)의 접히는 효과를 극대화시키기 위하여 접이주름(30)에 형성되는 만곡부(32)와 접이홈(33)을 수치한정하는 것이 바람직하다. 만곡부(32)가 최대 0.9mm보다 작게 되면 접히는 효과에 전혀 도움이 되지 않고, 만곡부(32)가 최대 1.5mm보다 크게 되면 제2모서리(22)와 제4모서리(24) 사이에 형성된 접이주름(30)이 접히는데 반발력으로 작용하여 오히려 방해가 된다. 또한, 접이홈(33)이 최대 0.9mm보다 작게 되면 공기를 주입하여 금형의 형상으로 페트병을 제조하는 과정에서 페트병에 접이홈(33)이 선명하게 나타나지 않게 되어 원활하게 접 히지 않고, 접이홈(33)이 최대 1.5mm보다 크게 되면 제1모서리(21)와 제3모서리(23) 사이에 형성된 접이홈(33)의 굴곡도 같이 커지게 되어 제2모서리(22)와 제4모서리(24) 사이에 형성된 접이주름(30)이 접히는데 반발력으로 작용하므로 오히려 접히는 효과가 현저하게 감소하게 된다.On the other hand, in order to maximize the folding effect of the curved folding surface 20, it is preferable to numerically limit the curved portion 32 and the folding groove 33 formed in the folding wrinkles (30). If the curved portion 32 is smaller than the maximum 0.9mm, it is not helpful to the folding effect at all, and when the curved portion 32 is larger than the maximum 1.5mm, the folding wrinkles formed between the second corner 22 and the fourth corner 24 ( 30) acts as a repulsive force to fold, rather hinders. In addition, when the folding groove 33 is smaller than the maximum 0.9mm, in the process of manufacturing the PET bottle in the shape of a mold by injecting air, the folding groove 33 does not appear clearly in the PET bottle does not fold smoothly, folding groove ( When 33) is greater than 1.5 mm, the bending of the folding groove 33 formed between the first edge 21 and the third edge 23 is also increased, so that the second edge 22 and the fourth edge 24 are increased. Since the folding wrinkles 30 formed therebetween act as a repulsive force, rather the folding effect is significantly reduced.

이와 같이 제2모서리(22)와 제4모서리(24) 사이에 형성된 접이주름(30)이 접혀서 완전히 접히게 되면, 제1모서리(21)는 제3모서리(23)에 닿게 되고 용적이 최소화된 상태에서 마개를 닫아 분리수거를 하면 된다.As such, when the folding wrinkles 30 formed between the second corners 22 and the fourth corners 24 are folded and completely folded, the first corners 21 are in contact with the third corners 23 and the volume is minimized. In the state, you can close the cap and separate the collection.

또한, 빈 용기를 가지고 등산하여 약수를 받아올 경우에는 먼저 본 발명에 따른 용적변형 페트병의 상부와 하부를 서로 반대방향으로 회전시켜 용적을 줄인 상태에서 마개를 닫아 휴대하면 편리하다.In addition, when climbing the mountain with an empty container, it is convenient to carry the cap closed in the state of reducing the volume by rotating the upper and lower portions of the volumetric plastic bottle according to the present invention in the opposite direction.

한편, 공기를 주입하여 금형의 형상으로 페트병을 제조하는 과정에서 단수주름(10)이 원형에 가까울수록 금형의 형상대로 페트병이 제조되므로 정팔각형 단수주름(10)을 가진 본 발명에 따른 용적변형 페트병의 생산성은 크게 향상되게 된다.On the other hand, in the process of manufacturing the PET bottle in the shape of the mold by injecting air, the closer the sprinkler (10) is rounded, the volume of the plastic bottle according to the present invention having a square octagonal single wrinkle (10) because the PET bottle is manufactured in the shape of the mold Productivity will be greatly improved.

또한, 접이면(20)에는 "X"자형의 접이주름(30)이 형성되어 있으므로 본체(1)의 상부를 시계 방향으로, 하부를 반시계 방향으로 회전시켜 접히는 방향이 바뀌게 할 수도 있다.In addition, since the folding face 30 of the “X” shape is formed in the folding surface 20, the folding direction may be changed by rotating the upper part of the main body 1 clockwise and the lower part counterclockwise.

본 발명의 바람직한 실시예는 단수주름(10)이 정팔각형인 경우에 관해 기술하였지만, 본 발명은 단수주름(10)이 정십이각형 등과 같이 원형에 가까운 단수주름(10)을 가진 페트병 또는 합성수지 용기에도 균등하게 적용될 수 있을 것이다.Although the preferred embodiment of the present invention has been described with respect to the case where the singular wrinkles 10 are regular octagons, the present invention is a PET bottle or plastic container having a singular wrinkles 10 having a singular wrinkle (10) close to a circle such as a regular pentagon, etc. May be equally applied.

이상에서 설명한 본 발명의 용적변형 페트병은 내부에 담겨있는 음료수를 마신 후에 빈 페트병의 용적을 축소하는 것이 가능하여 수거시의 부피를 획기적으로 줄여 환경오염을 방지하는 데 일조할 수 있고, 원상태로 복원하여 재사용할 수 있는 효과도 제공한다.The volume modified PET bottle of the present invention described above can reduce the volume of an empty PET bottle after drinking a beverage contained therein, which can help to prevent environmental pollution by dramatically reducing the volume at the time of collection and restoring to its original state. It also provides an effect that can be reused.

또한, 페트병의 본체에 형성된 정팔각형의 단수주름으로 인하여 단수주름 사이의 굴곡진 접이면이 접히는 효과를 크게 향상시키고, 접이주름에 형성된 만곡부과 접이홈의 수치한정을 통해 접히는 효과를 극대화시키면서 생산성도 크게 향상시킬 수 있다.In addition, due to the octagonal singular wrinkles formed on the body of the PET bottle, the curved folding surface between the singular wrinkles is greatly improved, and the productivity is greatly increased while maximizing the folding effect through the numerical limitation of the curved portion and the folding groove formed on the folding wrinkles.
