Problems solved by technology

[0007] However, the crushing of the shoulders and the bottom of the infusion container of Patent Document 1 is not sufficient, and therefore, the amount of injected air is large and there is an unsatisfactory structure. In addition, regarding the infusion container of Patent Document 2, although Some improvements can be recognized, but the shoulders and bottom, especially the shoulders, are not sufficiently flattened, so the amount of air injected is large, and there is dissatisfaction

Embodiment 1

[0076] First, use Figure 1 ~ Figure 5 Example 1 will be described.

[0077] figure 1 Is a front view showing the infusion container of Example 1, figure 2 Yes figure 1 Side view, image 3 Yes figure 1 Top view of Figure 4 Yes figure 1 X-X line end view, Figure 5 Yes figure 1 The end view of the Y-Y line.

[0078] The infusion container of Example 1 is such as Figure 1 ~ Figure 5 Shown is a blow-molded container with a mouth 1, a neck 2, a shoulder 3, a torso 4, and a bottom 5. The torso 4 has a pair of wider sides 41, 41 and a pair of narrower sides. The side surfaces 42 and 42, and the bottom part 5 are formed in a shape symmetrical about the long axis of the bottom part 5 and bent in a V shape toward the inside. In addition, the shoulder portion 3 has a pair of wide-width side surfaces 31, 31 and a pair of narrow-width side surfaces 32, 32. The narrow-width side surfaces 32, 32 are formed symmetrically with respect to the long axis and facing the inner side with a V S...

Embodiment 2

[0083] Next, use Figure 6 ~ Figure 10 Example 2 will be described.

[0084] Figure 6 Is a front view showing the infusion container of Example 2, Figure 7 Yes Figure 6 Side view, Figure 8 Yes Figure 6 Top view of Picture 9 Yes Figure 6 X-X line end view, Picture 10 Yes Figure 6 The end view of the Y-Y line.

[0085] The infusion container of Example 1 is such as Figure 6 ~ Figure 10 Shown is a container with a mouth 1, a neck 2, a shoulder 3, a torso 4, and a bottom 5. The torso 4 has a pair of sides 41, 41 with a wider width and a pair of sides 42 with a narrower width. 42. The bottom part 5 is formed in a shape symmetrical about the long axis of the bottom part 5 and bent in a V shape toward the inside. In addition, the shoulder 3 has a pair of wider side faces 31, 31 and a pair of narrower side faces 32, 32. On the narrower side faces 32, 32 of the shoulder 3, there are arranged symmetrical and symmetrical about the long axis. The creases 321 and 321 bent outward. I...

Embodiment 5

[0089] The infusion container 100 of Example 5 is as Figure 12 ~ Figure 13 Shown is a blow-molded container with a mouth 101, a neck 102, a shoulder 103, a torso 104, and a bottom 105. The torso 104 has a pair of wider sides 141, 141' and a pair of narrower sides. The side surfaces 142, 142' of the bottom 105 are formed symmetrically with respect to the long axis X of the bottom 105 and are bent in a V shape toward the inside. The ground portion ridge line 152 is formed parallel to the long axis of the bottom and along the long axis The direction becomes a straight line. In addition, the shoulder 103 has a pair of side surfaces 131, 131' with a relatively wide width and a pair of side surfaces 132, 132' with a relatively narrow width. The grooves 133, 133' curved in a V shape on the inside. In addition, in the case of blow molding, generally the wider side surfaces 131, 141 of the shoulder 103 and the trunk 104 are symmetrical about the minor axis Y, and the narrow side surfaces 1...

Abstract

Provide is a bottle-type blow-molded plastic infusion container that can be set in an upright position. When liquid is discharged from the container, almost no dead space occurs in shoulder and bottom portions (required amount of air to be placed in the container to remove residual liquid is less). The blow-molded container has a mouth section (1), a neck section (2), the shoulder section (3), a barrel section (4), and the bottom section (5). The barrel section (4) has a pair of broad side faces (41, 41) and a pair of narrow side faces (42, 42). The bottom section (5) is formed in a shape symmetrical about a longitudinal axis of the bottom section (5) and bent inward in a V shape. Further, the shoulder section (3) has a pair of broad side faces (31, 31) and a pair of narrow side faces (32, 32). In the narrow side faces (32, 32) are formed grooves (33, 33) symmetrical about a longitudinal axis and bent inward in a V shape.

Description

Technical field [0001] The present invention relates to a plastic blow-molded infusion container for storing infusion or glucose used in drip therapy or the like. Background technique [0002] As a plastic infusion container, a bag-shaped container formed of a plastic sheet and a plastic bottle-shaped container formed by blow molding are conventionally known. [0003] The bottle-shaped infusion container has the advantage of being able to make the infusion container upright. However, since this type of infusion container is formed by blow molding, it has a problem in terms of flexibility. Therefore, since the container is not sufficiently crushed during the outflow of the liquid medicine, it has the disadvantage that a considerable amount of liquid medicine remains. Therefore, in the past, when the liquid medicine was infused at a constant flow rate, for example, an air needle was pierced into the plug at the mouth of the container to connect the inside and outside of the contain...
