下タイプのプラスチック容器に関するものである。[Detailed Description of the Invention] [Field of Industrial Application] The present invention is applicable to intravenous infusions such as carbohydrate infusions, electrolyte infusions, plasma expanders, osmotic diuretics, amino acid infusions, fat emulsions, high-calorie infusions, etc. It is a flexible plastic container that is filled with medical solutions for injectable infusions, enteral nutritional supplements, high-protein nutritional supplements, component nutritional supplements, and enteral high-calorie nutritional supplements such as liquid foods. This invention relates to a so-called natural drip type plastic container that is deformed to administer a medicinal solution.
［従来の技術］
落としても割れないこと、軽量であるなどの利点により
、近年薬液容器のプラスチック化が急速に進んでいる。[Prior Art] In recent years, the use of plastic containers for chemical solutions has rapidly progressed due to their advantages such as not breaking when dropped and being lightweight.
なかでも、プラスチック材料の柔軟性を利用して、胴部
を変形させて薬液の投与をおこなう自然滴下タイプのも
のが多用されている。Among these, the natural drip type, which uses the flexibility of the plastic material to deform the body and administer the drug, is often used.
これは、自然滴下の場合、容器内に空気を供給すること
なく投与が行え、従って容器内に雑菌の侵入の心配のな
い衛生上の利点を有するためである。This is because, in the case of natural dripping, administration can be carried out without supplying air into the container, and therefore, it has a hygienic advantage in that there is no fear of germs entering the container.

There is one described in Japanese Patent No. 58955 (hereinafter referred to as "prior publication"). This shows a plastic container for medicinal liquids which integrally has a body portion having an elliptical cross-sectional shape, a mouth portion sealed with a stopper on the upper edge of the body, and a hanger integrally attached to the lower edge of the body.

Because of this, deformation due to back pressure during natural dripping will no longer occur in this portion, and the chemical solution will remain in this portion at the final stage of dripping. Natural dripping due to back pressure mainly acts on the upper part of the chemical solution and deforms it from the upper side. For this reason, the deformation during natural dripping occurs last on the mouth side, and forming an angular shoulder in this way makes it difficult for back pressure to be transmitted, and this portion does not deform and creates a dead space during dripping. Moreover, since the shoulder portion has a lower ability to accumulate the drug solution than its shape, a portion where the drug solution remains is formed.

を提供することをを目的とするものである。SUMMARY OF THE INVENTION Therefore, an object of the plastic container for chemical solutions of the present invention is to provide a container for chemical solutions that has a large ability to accumulate medical solutions during natural dripping and does not generate dead spaces due to deformation due to back pressure. It is something.

器かえられるものである。[Function] The plastic container for medical solutions of the present invention has a flat body whose cross-sectional shape has a width on the major axis of 2.0 or more relative to the width on the minor axis, and a hanging portion on the upper edge of the body. This blow-molded plastic container for chemical liquids has a mouth formed at the center of the lower edge of the body, so back pressure is efficiently applied to the body during natural dripping, and an efficient natural dripping condition can be achieved. At the same time, the shape of the lower end edge of the body is formed such that the shape of the surface parallel to the short axis side of the lower cross section of the body is wedge-shaped, and the shape of the surface parallel to the long axis side is shaped toward the mouth. Since it has a shrinking funnel shape, it has a large ability to accumulate a chemical solution and does not form a dead space, making it possible to replace a plastic blow container for a chemical solution.

ている。Reference numeral 1 designates a plastic blow container for infusion, which is composed of a body part 2, a hanging part 4 integrally connected to the upper edge 3 of the body part 2, and a mouth part 6 formed on the lower edge 5 of the body part 2. ing. The end of the mouth portion 6 is sealed by welding with a plug body 7 having a rubber stopper inside. The body portion 2 has a flat cross-sectional shape, and the ratio B/A of the width B on the long axis side to the width A on the short axis side shown in FIG. 2 is about 2.5. This B/A needs to be at least 2.0. B/A is 2.
If it is less than 0, deformation due to back pressure during natural dripping will not proceed with a small force, and the deformation will stop midway through the dripping, resulting in residual chemical solution. The shape of the surface parallel to the short axis side of the lower cross section of the body is formed into a wedge shape, and the shape of the surface parallel to the long axis side is formed into a funnel shape that decreases toward the mouth 6.

され排出された。At this time, the shape of the surface parallel to the short axis side of the lower cross section of the body is formed into a wedge shape, and the shape of the surface parallel to the long axis side is formed into a funnel shape that reduces toward the mouth 6. Therefore, during natural dripping, the infusion solution was efficiently accumulated and discharged at the lower part of the body.
