Passage; An airless discharge pump fixed to the top of the outer container to be inserted into the inner container by screwing the pump cap to the male thread portion; a first rotation-permitting coupling portion provided at the top of the inner container to face upward; And when the pump cap is screwed to the male screw portion. It is provided to face downward on the inside of the pump cap in order to be fitted into the first rotation-permitting coupling portion to prevent separation, and is rotatable from the first rotation-permitting coupling portion while being inserted into the first rotation-permitting coupling portion. It includes a second rotation-permitting coupling portion.
이와 같은 종래 기술은 내부 용기와 외부 용기의 2중 구조 특성상 블로우(Blow) 성형 공정으로 제작되는데, 외부용기의 개구와 내부용기의 출입구가 에어리스 배출펌프의 펌프캡에 나사결합 및 끼움결합으로 고정됨으로써, 외부용기의 입구측과 내부용기의 입구측이 겹쳐질 수밖에 없는 구조를 가지게 되고, 이로 인해, 블로우 성형 공정시, 고온으로 인해 외부용기의 입구측과 내부용기의 입구측이 부착되어, 폐기시 내부용기를 외부용기로부터 분리시키는데 어려움이 따르는 문제점을 가지고 있었다.This prior art is manufactured through a blow molding process due to the dual structure nature of the inner and outer containers. The opening of the outer container and the entrance of the inner container are fixed to the pump cap of the airless discharge pump by screwing and fitting. , it has a structure in which the inlet side of the outer container and the inlet side of the inner container inevitably overlap, and as a result, during the blow molding process, the inlet side of the outer container and the inlet side of the inner container become attached due to high temperature, resulting in waste when discarded. There was a problem in that it was difficult to separate the inner container from the outer container.

The external container 110 is exemplified as having a cylindrical shape, but it is not necessarily limited to this and, of course, may have various shapes.
외부용기(110)는 후술하게 될 펌프캡(121)과는 분리되되(도 1, 도 2 및 도 4 참조), 삽입공간(111)의 입구(112)의 상단에 직경이 확장되어 펌프캡(121)의 하단을 지지하기 위한 확장지지부(113)가 일체로 형성될 수 있는데, 이러한 확장지지부(113)에 의해 하방으로 가압력이 작용하는 에어리스 배출펌프(120)의 펌프캡(121) 하단을 안정적으로 지지하도록 할 수 있다.The external container 110 is separated from the pump cap 121, which will be described later (see FIGS. 1, 2, and 4), and has an expanded diameter at the top of the inlet 112 of the insertion space 111 to form a pump cap ( An extended support part 113 to support the lower end of the 121) may be formed integrally. This extended support part 113 stabilizes the lower end of the pump cap 121 of the airless discharge pump 120, which exerts downward pressure. It can be supported by .
외부용기(110)는 삽입공간(111) 내에 삽입된 내부용기(130)의 압축으로 인해 삽입공간(111) 내에 형성되는 부압을 해소하도록 외기가 유입되는 압축유입홀(114)이 적어도 하나 이상 형성될 수 있다. 따라서, 압축유입홀(114)에 의해 외부용기(110)의 내측으로 외기가 유입될 수 있게 됨으로써, 내부용기(130)의 압축이 원활하게 이루어지도록 할 수 있다.The outer container 110 has at least one compression inlet hole 114 through which external air flows to relieve the negative pressure formed in the insertion space 111 due to compression of the inner container 130 inserted into the insertion space 111. It can be. Therefore, by allowing external air to flow into the inside of the outer container 110 through the compression inlet hole 114, the compression of the inner container 130 can be performed smoothly.

It is made of a material that shrinks due to negative pressure formed on the inside, so that it can be separated from the external container 110 along with the airless discharge pump 120 when discarded due to shrinkage (see FIG. 4). Here, the contents may include cosmetics as an example, but are not limited to this and may include not only chemicals such as drugs or syrups, but also various liquid substances. The inner container 130 does not provide a structure in which the outer surface is fitted with the inner surface of the outer container 110, so that the outer surface is separated from the inner surface of the outer container 110 by shrinkage (Figure 1, 2 and 4).
외부용기(110)와 내부용기(130)는 일례로, 서로 겹쳐진 상태에서 프리폼 사출 성형 내지 블로우 성형에 의해 원하는 부피와 형태를 가지도록 제작될 수 있는데, 이에 한하지 않고, 다른 예로서, 구조적으로 허용되는 범위 내에서 각각 개별적으로 제작되어 서로 겹쳐지도록 제조될 수 있음은 물론이다.For example, the outer container 110 and the inner container 130 may be manufactured to have a desired volume and shape by preform injection molding or blow molding in an overlapping state. However, this is not limited to this, and as another example, they are structurally Of course, they can be manufactured individually and overlap each other within the allowable range.
내부용기(130)는 펌프캡(121)의 암나사부(122)에 나사 결합되기 위한 수나사부(134)가 돌출부(133)의 외주면에 형성될 수 있다.The inner container 130 may have a male thread 134 formed on the outer peripheral surface of the protrusion 133 to be screwed to the female thread 122 of the pump cap 121.

It can be included. Therefore, when using the blow molding process after assembling the outer container 110 and the inner container 130 or after completing the manufacturing, the negative pressure formed in the outer container 110 by the contraction of the inner container 130 is reduced to air. By being released through the inflow passage 140, blow molding and use by compression of the inner container 130 can be performed smoothly. Meanwhile, as in Figures 1 and 3, the air inlet passage 140 is formed inside the inlet 112 of the outer container 110, but this is not necessarily limited, and as another example, the inner container 130 Of course, it may be formed inside the inlet 132 of ).
