Description

이중컵의 제조방법 및 그의 방법으로 제조된 이중컵Method for producing a double cup and a double cup manufactured by the method
본 발명은 외컵과 내컵을 결합하여 완성되는 이중컵, 외컵·내컵을 제조하고 완성된 외컵·내컵을 결합하여 이중컵을 제조하는 이중컵 제조방법, 그리고 상기 이중컵 제조방법에 의하여 제조된 이중컵에 관한 것이다.The present invention is a double cup to produce a double cup, the outer cup and the inner cup is completed by combining the outer cup and the inner cup, and a double cup manufacturing method for producing a double cup by combining the completed outer cup and inner cup, and the double cup manufactured by the double cup manufacturing method It is about.
일반적으로 일회용 컵은 종이를 재질로 한 단일 컵이 사용된다. 이러한 일회용 종이컵은 방수를 위해서 주로 LDPE로 코팅을 하는데, LDPE는 고온의 음료를 수용할 경우 음료가 산화하거나 변질되는 문제점이 있으며, 음료의 고온이 외부로 전달되기 때문에 고온의 음료가 수용된 일회용 종이컵의 파지를 위해서는 별도의 홀더가 필요하다.Disposable cups are generally used as single cups made of paper. These disposable paper cups are mainly coated with LDPE for waterproofing. LDPE has a problem that beverages are oxidized or deteriorated when accommodating high temperature beverages. A separate holder is required for gripping.
또한, 기존의 이중컵의 경우 외컵과 내컵을 결합하여 이중컵을 제조하는 공정 과정에서 약간의 공정상 오류에도 파손될 수 있어서 공정 불량률이 높고, 완성된 이중컵이 포개지는 구조가 부피를 너무 많이 차지하여 포장과 운송에서 비효율이 발생하는 문제점이 있다.In addition, in the case of the existing double cup, the process of manufacturing the double cup by combining the outer cup and the inner cup may be damaged even with a slight process error, and thus the process defect rate is high, and the structure of the overlapped double cup takes up too much volume. There is a problem that inefficiency occurs in packaging and transportation.
따라서, 본 발명은 상기한 문제점을 해결하기 위하여 제안된 것으로써, 본 발명의 목적은 수용된 음료의 온도의 전도율이 낮아서 홀더 없이도 손쉽게 파지할 수 있는 이중컵을 제공하는 데 있다.Accordingly, the present invention has been proposed to solve the above problems, and an object of the present invention is to provide a double cup which can be easily gripped without a holder due to low conductivity of the temperature of the contained beverage.
또한, 본 발명은 약간의 압력을 가하는 것만으로 손쉽게 외컵과 내컵을 결합하여 완성할 수 있어서 작업이 용이하고, 약간의 오차가 있더라도 외컵과 내컵의 위치가 자동적으로 조절되어 공정상 불량률을 낮출 수 있는 이중컵의 제조방법을 제공하는 데 있다.In addition, the present invention can be easily completed by combining the outer cup and the inner cup simply by applying a little pressure, and even if there is a slight error, the position of the outer cup and the inner cup is automatically adjusted to lower the defective rate in the process. It is to provide a method for producing a double cup.
또한, 본 발명은 포개어진 컵들로부터 분리시킬 때 분리가 용이하면서도 포개어서 적재할 때 적재 부피가 작은 구조를 가지는 이중컵을 제공하는 데 있다.In addition, the present invention is to provide a double cup having a structure that is easy to separate when the separation from the stacked cups, while having a small loading volume when stacked.
상기와 같은 본 발명의 목적을 달성하기 위하여, 본 발명은 외컵 본체 및 컬링부를 포함하는 외컵, 그리고 내컵 본체 및 컬링결합부를 포함하는 내컵을 포함하며 컬링부를 컬링결합부에 끼움 결합함으로써 외컵과 내컵이 결합되는 이중컵을 제공한다.In order to achieve the object of the present invention as described above, the present invention includes an outer cup including an outer cup body and a curling portion, and an inner cup including an inner cup body and a curling coupling portion, and the outer cup and the inner cup are fitted by fitting the curling portion to the curling coupling portion. Provide a double cup to be combined.
또한, 상기 내컵은 컬링결합부에서 연장되는 가이드부 및 가이드부에서 연장되는 말단부를 포함하는 것이 바람직하다.In addition, the inner cup preferably includes a guide portion extending from the curling coupling portion and a distal end portion extending from the guide portion.

도 5a와 도 5b는 본 발명의 실시 예에 따른 이중컵의 분해도이고, 도 6a와 도 6b는 이중컵의 사이드공간부와 바닥공간부를 나타낸다.5A and 5B are exploded views of a double cup according to an exemplary embodiment of the present invention, and FIGS. 6A and 6B show side space portions and bottom space portions of the double cup.
첨부된 도 5a 내지 도 6b를 참조하면, 본 발명의 실시 예에 따른 이중컵의 결합 관계 및 효과는 다음과 같다.5A to 6B, the coupling relationship and effect of the double cup according to the embodiment of the present invention are as follows.
외컵(10)과 내컵(20)의 결합은 내컵 본체(22)는 내컵수용부(14)에 수용됨으로써 이루어질 수 있다. 내컵 본체(22)가 내컵수용부(14)에 수용될 때 컬링결합입구부(36)의 직경이 컬링부(16)의 직경보다 작기 때문에 도 5a와 같이 컬링부(16) 위에 가이드부(38)가 얹혀진 상태가 되고, 내컵 본체(22)는 내컵수용부(14)와 완전히 밀착되지 못한 상태이다.The combination of the outer cup 10 and the inner cup 20 may be made by receiving the inner cup body 22 in the inner cup receiving portion 14. When the inner cup main body 22 is accommodated in the inner cup receiving portion 14, the diameter of the curling coupling inlet portion 36 is smaller than the diameter of the curling portion 16, and thus the guide portion 38 on the curling portion 16 as shown in FIG. 5A. ) Is placed on the state, the inner cup body 22 is not in close contact with the inner cup receiving portion (14).
이때, 내컵 본체(22)를 내컵수용부(14) 쪽으로 힘을 가하여 밀어 넣으면, 컬링결합입구부(36)가 바깥쪽으로 벌어지면서 컬링부(16)가 컬링결합부(34) 내부로 들어가게 되고, 탄성력에 의하여 컬링결합입구부(36)가 리턴 되면 컬링부(16)가 컬링결합부(34)에 결합되고, 이에 따라 사이드돌출부(26)가 외컵 본체(12)의 내부와 밀착되고 바닥돌출부(30)가 외컵 본체(12)의 바닥 내부와 밀착되어 내컵 본체(22)가 내컵수용부(14)에 완전히 수용된다.At this time, when the inner cup main body 22 is pushed into the inner cup receiving portion 14 by force, the curling coupling inlet portion 36 is opened outwards, and the curling portion 16 enters into the curling coupling portion 34. When the curling coupling inlet portion 36 is returned by the elastic force, the curling portion 16 is coupled to the curling coupling portion 34. As a result, the side protrusion 26 is in close contact with the inside of the outer cup body 12 and the bottom protrusion portion ( 30 is in close contact with the bottom of the outer cup body 12 so that the inner cup body 22 is completely accommodated in the inner cup receiving portion 14.
외컵(10)과 내컵(20)이 결합되면, 사이드돌출부(26)가 외컵 본체(12)의 내벽에 밀착되고 사이드홈부(28)와 외컵 본체(12)의 사이드 내부는 사이드공간부(29)를 형성한다.When the outer cup 10 and the inner cup 20 are combined, the side protrusion 26 is in close contact with the inner wall of the outer cup body 12, and the side insides of the side grooves 28 and the outer cup body 12 are side space portions 29. To form.
또한, 외컵(10)과 내컵(20)이 결합되면, 바닥돌출부(30)가 외컵 본체(12)의 내부 바닥면에 밀착되고 바닥홈부(32)와 외컵 본체(12)의 내부 바닥면은 바닥공간부(33)를 형성한다.In addition, when the outer cup 10 and the inner cup 20 are coupled, the bottom protrusion 30 is in close contact with the inner bottom surface of the outer cup body 12 and the bottom groove 32 and the inner bottom surface of the outer cup body 12 are bottomed. The space 33 is formed.
사이드공간부(29)와 바닥공간부(33)는 외컵(10)의 내주면과 내컵(20)의 외주면 사이에 복수의 단열 공간을 형성하게 되므로, 내용물에 대한 단열 효과, 파지 시의 손가락 및 손바닥에 대한 단열효과를 가진다. 따라서, 기존의 종이컵의 경우 뜨거운 내용물이 담긴 종이컵을 파지하기 위해 별로도 홀더가 필요했지만, 본 발명에 따른 이중컵은 뜨거운 음료가 수용되더라도 홀더 없이 파지할 수 있다.Since the side space portion 29 and the bottom space portion 33 form a plurality of thermal insulation spaces between the inner circumferential surface of the outer cup 10 and the outer circumferential surface of the inner cup 20, the insulation effect on the contents, fingers and palms when holding It has a thermal insulation effect on Therefore, in the case of a conventional paper cup, a holder is required separately to hold a paper cup containing hot contents, but the double cup according to the present invention can be held without a holder even if a hot drink is accommodated.
또한, 기존의 일회용 종이컵의 경우, 음료를 수용하기 위해 LDPE를 코팅하여 종이 음료가 스며들지 않도록 하였다. 그런데, LDPE는 고온의 음료를 수용할 경우 음료가 산화하거나 변질될 수 있어서, 음료가 수용되는 즉시 산폐과정이 진행되어 음료의 맛이 변질되는 문제점이 있었다. 본 발명에 따른 이중컵의 경우에는 LDPE 코팅이 필요하지 않기 때문에 음료가 산폐되지 않고 음료 본래의 맛을 즐길 수 있는 효과가 있다.In addition, in the case of the conventional disposable paper cup, the LDPE coating to accommodate the beverage to prevent the paper beverage penetrates. However, LDPE may be oxidized or deteriorated when the beverage is accommodated at a high temperature, so that the beverage is oxidized or deteriorated as soon as the beverage is accommodated. In the case of the double cup according to the present invention, since the LDPE coating is not necessary, the beverage is not pulverized and there is an effect of enjoying the original taste of the beverage.
또한, 포개진 상태에서의 완성된 이중컵은 하부 이중컵의 컬링결합부(34)와 상부 이중컵의 말단부(40)가 접촉된 상태에서 포개지기 때문에, 포개진 상태에서 분리가 용이하면서도 포개졌을 때 전체 적재 공간이 과다하지 않은 효과가 있다.In addition, since the completed double cup in the folded state is stacked in contact with the curling coupling portion 34 of the lower double cup and the distal end portion 40 of the upper double cup, it is easy to separate and overlapped in the folded state. When the whole loading space is not excessive effect.
