Embodiment Construction

[0026] The following will describe it in conjunction with different embodiments of the present invention. Those skilled in the art can know that the technical features and objectives of the present invention can be realized through various alternative technical solutions without creative work. Therefore, the embodiments described below are only illustrative and not restrictive.

[0027] refer to figure 1 , figure 2 and image 3 . The infusion container provided by the present invention is an integrally formed flexible flat bag-shaped container, comprising: a mouth 100 leading to the inside of the container, a body 200 connected with the mouth 100 , and a bottom 300 connected with the body 200 . The body 200 includes a first side wall 201 and a second side wall 202 , and a first face 203 and a second face 204 . There is a first convex wall 205 and a second convex wall 206 between the mouth 100 and the body 200, a third convex wall 207 and a fourth convex wall 208 between t...

Abstract

The invention relates to a seamless and transparent soft plastic infusion bag packing container which is manufactured from the raw material of polypropylene by adopting a two-step blow molding technology. The soft plastic infusion bag packing container is an integrated soft and flat bag-shaped container and comprises an opening part, a body part and a bottom part which are integrated into a whole. The cross section of the infusion container is 2 to 4 times as long as the width, thus the infusion container can contract inwards and deform easily along the short shaft direction. The infusion container is used without adopting an air needle, and the liquid in the infusion container flows out stably at an appropriately constant speed in the infusing process. The surface of the infusion container in the short shaft direction contracts inwards regularly, and irregular bending such as twisting does not occur to the surface.

Description

technical field [0001] The invention relates to an infusion container, in particular to a seamless and transparent plastic infusion soft bag packaging container produced by using polypropylene as a raw material and using two-step blow molding technology. Background technique [0002] At present, the infusion packaging containers commonly used in the domestic and foreign markets mainly include glass bottles, plastic bottles, and non-PVC composite film soft bags. Among them, glass bottles have disadvantages such as fragility, heavy weight, inconvenient transportation and unfavorable recycling, and their share in the market is getting smaller and smaller. The non-PVC composite film soft bag does not need an air needle when in use, and can freely shrink and deform inwardly by relying on the effect of the external atmospheric pressure, and the liquid in the container can be drained by itself. It can prevent the air in the environment from polluting the drug, and ensure the effic...
