Description

Shopping bag using polypropylene film {A SHOPPING BAG}

본 고안은 폴리프로필렌 필름을 이용한 쇼핑백에 관한 것으로, 특히 전개된 상태의 필름을 절첩하는 작업은 물론 절첩된 필름의 결합부위를 초음파장치에 의해 접합하는 작업이 효과적이면서 견고하게 제공되는 폴리프로필렌 필름을 이용한 쇼핑백에 관한 것이다.The present invention relates to a shopping bag using a polypropylene film, in particular, the operation of folding the film in the unfolded state, as well as bonding the bonding portion of the folded film by the ultrasonic device effectively and securely provides a polypropylene film It is about the shopping bag used.

일반적으로 쇼핑백은 간단한 물건을 운반 또는 보관하기 위하여 흔히 사용되고 있다.In general, shopping bags are commonly used to carry or store simple items.

이러한 쇼핑백은 주로 종이를 이용하여 제조하기 때문에 강도가 약하고 특히 습기에 약하여 쉽게 훼손되고, 장 기간 사용할 수 없는 문제점이 있었다.Such shopping bags are mainly made of paper, so the strength is weak, and particularly weak to moisture, which is easily damaged and has a problem that cannot be used for a long time.

이러한 문제 때문에 근래에는 합성수지 필름을 이용한 쇼핑백이 제공되어 오고 있다.Recently, shopping bags using a synthetic film have been provided because of this problem.

이러한 합성수지 필름을 이용한 쇼핑백은 첨부한 도 1과 같이 전개된 사각형의 필름(1)을 제작하여 양측과 상하단을 절첩한 후 각 결합부위를 초음파장치에 의해 접합하여 도 3와 같은 쇼핑백(5)을 제조하였다.The shopping bag using the synthetic resin film is to produce a rectangular film (1) unfolded as shown in Figure 1 and folded both sides and the upper and lower ends, and then bonded to each of the coupling portion by the ultrasonic device to the shopping bag (5) as shown in FIG. Prepared.

이를 좀더 상세히 설명하면, 전개된 필름(1)의 양측은 절첩선(2)에 의해 내측으로 "V"자형으로 절첩되도록 측면절첩부(3)(3')를 절첩형성하고, To explain this in more detail, both sides of the unfolded film 1 folds the side folds 3, 3 ′ so as to be folded inwardly into a “V” shape by the fold lines 2,

상기 필름(1) 상측은 절첩선(2')에 의해 단부를 따라 내측으로 절첩하여 상단절첩부(4)를 형성하며,The upper side of the film (1) is folded inward along the end by the fold line (2 ') to form the upper fold (4),

상기 필름(1)의 하측은 절첩선(2")에 의해 양측이 측면절첩부(3)(3')와 경계되는 위치로 삼각형으로 절첩되는 좌우 받침부(5)(5')와 전후 받침부(6)(6')를 형성하여서 상기 좌우 받침부(5)(5')저면으로 전후 받침부(6)(6')가 포개지도록 절첩된 하단 절첩부(7)를 절첩 형성하게 된다.The lower side of the film 1 is the front and rear supporting portions 5 and 5 ', which are folded in a triangle to a position where both sides are bounded by the side folding portions 3 and 3' by a folding line 2 ". By forming the portions 6, 6 ', the bottom folded portions 7 folded to fold the front and back supporting portions 6, 6' to the bottom of the left and right supporting portions 5, 5 'are folded. .

그리고, 상기 측면절첩부(3)와 하부절첩부(7)의 결합부위에는 초음파에 으한 열 융착으로 접합 고정하게 된다.Then, the joint portion of the side folding portion 3 and the lower folding portion 7 is bonded and fixed by thermal fusion with ultrasonic waves.

또한, 상기 상단절첩부(4)에는 손잡이(8)를 조립하게 된다.In addition, the upper end portion 4 is assembled with a handle (8).

그러나 상기한 종래의 합성수지 필름을 이용한 쇼핑백은 다음과 같은 문제점이 있었다.However, the shopping bag using the conventional synthetic resin film has the following problems.

첫째, 필름의 절첩작업이 매우 불편하였다.First, the folding work of the film was very inconvenient.

그 이유는 필름(1)이 단순히 사각형태로 제작된 상태에서 하단 절첩부(7)가 절첩되기 때문이다.This is because the bottom folded portion 7 is folded in a state where the film 1 is simply produced in a rectangular shape.

다시말하면, 하단절첩부(7) 끝단이 수평을 이루는 필름을 절첩하면서 좌우받침부(5)(5')와 전후 받침부(6)(6')가 그 연결되는 부위(A)와 함께 여러 겹으로 포개지면서 절첩되기 때문에 그 절첩작업이 매우 불편하였다.In other words, while folding the film in which the lower end portion 7 ends horizontally, the left and right supporting portions 5, 5 'and the front and rear supporting portions 6, 6' are joined together with the portion A connected thereto. The folding work was very inconvenient because it was folded and folded.

둘째, 상기와 같이 하단절첩부(7)의 경우에 끝단이 수평을 이루는 필름을 절첩하면서 좌우받침부(5)(5')와 전후 받침부(6)(6')가 그 연결되는 부위(A)와 함께 여러 겹으로 포개지면서 절첩되기 때문에 열 융착에 의한 접합작업이 효과적으로 이루어지지 않게 되는 문제를 유발하였다.Second, in the case of the lower end portion 7 as described above, while folding the film of which the ends are horizontal, the left and right supporting portions 5, 5 'and the front and rear supporting portions 6, 6' is connected ( Since it is folded with several layers together with A), it causes a problem that the joining work by heat fusion cannot be performed effectively.

즉, 상기 하단절첩부(7)는 좌우받침부(5)(5')와 전후 받침부(6)(6')가 상호 열 접착이 충분히 이루어지지 않는 불량이 발생하면서 쉽게 분리되는 문제를 야기시키는 것이다.That is, the bottom folded portion 7 causes a problem that the left and right support portions 5, 5 'and the front and back support portions 6, 6' are easily separated while a defect that is not sufficiently thermally bonded to each other occurs. It is to let.

셋째, 상기 측면절첩부(3)의 상단 결합 부위(B)는 타측단과 상호 삽입되는 상태로 열 융착하게 되는데, 상기 결합 부위를 상호 삽입하는 작업이 매우 불편하였다.Third, the upper coupling portion (B) of the side folding portion (3) is thermally fused in a state that is inserted into the other end with each other, it was very inconvenient to insert the coupling portion.

따라서 본 고안은 상기와 같은 종래 기술의 문제점을 해결하고자 안출된 것으로서, 전개된 상태의 필름을 절첩하는 작업은 물론 절첩된 필름의 결합부위를 초음파장치에 의한 접합작업이 효과적이면서 견고하게 제공되는데 그 목적이 있다.Therefore, the present invention was devised to solve the problems of the prior art as described above, and the bonding work of the folded film as well as the bonding operation of the folded film by the ultrasonic apparatus is provided effectively and firmly. There is a purpose.

이러한 본 고안의 목적은 전개된 필름의 양측으로 측면절첩부와; 상단에 상단절첩부와; 하단에 좌우 받침부와 전후 받침부를 형성하여서 상기 좌우 받침부 저면으로 전후 받침부가 포개지도록 절첩된 하단 절첩부;를 절첩 형성하여 각 결합부위를 열 융착 접합 고정한 것에 있어서, 상기 하단 절첩부는 전후 받침부의 양측에 좌우 받침부와 연결되는 부위로 "" 형상의 절결부를 대향되게 절결 형성하여 상기 좌우 받침부 저면으로 전후 받침부가 밀착되게 절첩되어 열 융착 접합한 것에 의해 달성된다.The object of the present invention is the side-folded to both sides of the developed film; An upper fold portion at the top; Forming a left and right support portion and a front and rear support portion at a lower end thereof and folding the front and rear support portions onto the bottom of the left and right support portions; It is a part connected to the left and right support parts on both sides of the part. " It is achieved by forming a cutout of the shape opposite to each other, folding the front and rear bearing portions in close contact with the bottom of the left and right bearing portions, and thermally fusion bonding them.

이하 상기한 본 고안의 목적을 달성하기 위한 바람직한 실시예를 첨부 도면을 참조하여 살펴보기로 한다.Hereinafter, a preferred embodiment for achieving the above object of the present invention will be described with reference to the accompanying drawings.

본고안은 도 4 내지 도 7에 도시된 바와 같이, 일정 크기의 전개된 필름(1)의 양측 절첩선(2)에 의해 내측으로 절첩된 측면절첩부(3)(3)와, As shown in FIGS. 4 to 7, the present invention has side folding portions (3) (3) folded inward by both fold lines (2) of the unfolded film (1) of a predetermined size, and

상측 절첩선(2')에 의해 단부를 따라 내측으로 절첩된 상단절첩부(4)와, An upper fold portion 4 folded inward along an end by an upper fold line 2 ',

하측 절첩선(2")에 의해 양측이 측면절첩부(3)(3')와 경계되는 위치로 절첩되는 좌우 받침부(5)(5')와 전후 받침부(6)(6')를 형성하여서 상기 좌우 받침부(5)(5')저면으로 전후 받침부(6)(6')가 포개지도록 절첩된 하단 절첩부(7)를 절첩 형성하여 상기 측면절첩부(3)와 하단절첩부(7)의 결합부위를 열 융착에 의해 접합 고정한 것에 있어서,The left and right support portions 5, 5 'and the front and rear support portions 6, 6', which are folded to a position bordered by the side fold portions 3, 3 'by the lower fold line 2 ", Forming a lower fold portion 7 that is folded so that the front and rear support portions 6, 6 'are folded to the left and right support portions 5, 5' bottom. In the joining part of the sticking part 7 joined and fixed by heat fusion,

상기 하단 절첩부(7)는 전후 받침부(6)(6')의 양측에 좌우 받침부(5)(5')와 연결되는 부위로 "" 형상의 절결부(10)를 대향되게 절결 형성하여 상기 좌우 받침부(6)(6')저면으로 전후 받침부(6)(6')가 밀착되게 절첩되어 열 융착 접합하도록 이루어진다.The lower fold portion 7 is a portion connected to the left and right support portions 5, 5 'on both sides of the front and rear support portions 6, 6'. &Quot; shaped cutout portions 10 are formed to face each other so that the front and rear support portions 6 and 6 'are folded to be in close contact with the bottom of the left and right support portions 6, 6' and are thermally fused.

또한, 상기 상측 절첩부(4)의 절첩선(2')은 양단 결합부위로 "V"형 홈부(15)를 형성하여 구성한다.In addition, the fold line 2 'of the upper folded portion 4 is formed by forming the "V" type groove portion 15 at both ends of the coupling portion.

미설명부호로서, 50은 열융착 부위, 8은 손잡이를 나타내는 것이다.Unexplained reference numeral 50 denotes a heat-sealed portion and 8 denotes a handle.

다음은 상기와 같이 구성된 본 고안의 작용 및 작동에 대해 살펴보기로 한다.Next will be a look at the operation and operation of the subject innovation configured as described above.

먼저, 일정 크기의 전개된 필름(1)의 양측 절첩선(2)에 의해 내측으로 절첩된 측면절첩부(3)(3)를 형성하고, 상측 절첩선(2')에 의해 단부를 따라 내측으로 절첩된 상단절첩부(4)를 형성한다.First, the side folds 3 and 3 folded inwardly by the two fold lines 2 of the unfolded film 1 of a certain size are formed, and the inner fold lines 2 ′ are formed along the ends. The upper folded portion 4 is folded to form.

이 상태에서 상기 측면절첩부(3)(3')와 경계되는 위치로 하측 절첩선(2")에 좌우 받침부(5)(5')와 전후 받침부(6)(6')를 형성하되, 상기 전후 받침부(6)(6')의 양측에는 좌우 받침부(5)(5')와 연결되는 부위로 "" 형상의 절결부(10)를 대향되게 절결 형성하고 있기 때문에 종래와 같이 좌우받침부(5)(5')와 전후 받침부(6)(6')의 연결되는 부위가 함께 여러 겹으로 포개지면서 절첩되는 것이 아니라 상기 좌우 받침부(6)(6')저면으로 전후 받침부(6)(6')가 직접 밀착되게 절첩된 상태로 열 융착 접합하게 되는 것이다.In this state, left and right support portions 5, 5 'and front and rear support portions 6, 6' are formed on the lower fold line 2 "at a position bordered by the side fold portions 3, 3 '. However, on both sides of the front and rear support parts 6, 6 'to a portion connected to the left and right support parts 5, 5'. Since the cutouts 10 of the shape are cut out to face each other, the portions connected between the left and right supporters 5, 5 'and the front and back supports 6, 6' are overlapped in multiple layers as in the prior art. Rather than being folded while being built, the front and rear supporting parts 6 and 6 'are thermally fused and bonded in a state in which the front and rear supporting parts 6 and 6' are directly pressed to the bottom of the left and right supporting parts 6 and 6 '.

따라서, 상기 하단절첩부(7)는 좌우받침부(5)(5')와 전후 받침부(6)(6')의 그 연결부위가 절결된 상태로 되어 있어 필름이 포개지는 수효가 적게 되므로 절첩작업은 물론 열 융착작업이 효과적으로 이루어지게 되는 것이다.Therefore, the lower end folded portion 7 is in a state in which the connection portions of the left and right support portions 5, 5 'and the front and rear support portions 6, 6' are cut out, so that the number of overlapping films is reduced. The folding work as well as the thermal welding work will be done effectively.

또한, 본 고안은 상측 절첩부(4)의 절첩선(2') 양단 결합부위로 도 7에서와 같이 "V"형 홈부(15)를 형성하여서 직각인 종래의 경우에 비해 상기 결합부위를 상호 삽입하는 조립작업이 매우 편리하게 제공되는 것이다.In addition, the present invention forms a "V" type groove portion 15 as shown in FIG. 7 as a coupling portion at both ends of the fold line 2 'of the upper fold portion 4, so that the coupling portion is mutually perpendicular. The assembly work to insert is very convenient.

이상 상기에서 살핀 바와 같이, 본 고안의 쇼핑백은 절첩되거나 열 융착 결합되는 부위에 불필요하게 포개지는 부분을 절결한 상태로 작업하게 되므로 전개된 상태의 필름을 절첩하는 작업은 물론 절첩된 필름의 결합부위를 초음파장치에 의한 접합하는 작업이 효과적이면서 견고하게 제공되는 매우 유용한 고안임이 명백하다.As described above, as the shopping bag of the present invention works in a state in which the unnecessary overlapping portion is folded or heat-sealed, the folded state, as well as the operation of folding the film in the unfolded state of the combined film It is evident that the operation of bonding by means of an ultrasonic device is a very useful design that is provided effectively and robustly.
