Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to an outer bag that hermetically covers a container for infusion (medicine solution, etc.).

[0002]

[Prior art]

 For example, in a hospital or the like, a drip (injection) is performed to replenish a debilitated patient with a nutritional supplement. The infusion solution container a used for this drip has a shape as shown in FIG. It is made of a transparent material that allows oxygen to pass through. If a container a filled with such a chemical is mass-produced and stocked as it is, the chemical oxidizes for a long time and becomes unusable. In order to prevent such troubles, these chemical-filled containers are stored one by one by an outer bag b made of an oxygen-impermeable film or the like and kept in a sealed state.

[0003] By the way, such an outer bag b is not delivered in bulk as it is to be delivered from the production side to the user side, but is naturally delivered in a storage box.

[0004]

[Problems to be solved by the device]

 The outer bag b is provided with notches e as shown in FIG. 5 in the seal portions d on the left and right upper edges for facilitating the removal of the medicine filling container a contained therein. When viewed in an enlarged manner, the corner f has an angular notch shape as shown in FIG. 6, and therefore there is a problem that the user is injured when the corner f is touched by a fingertip or the like. It was In order to solve this problem, there is a perforation notch g provided in the length of about half the width of the sealing portion as shown in FIG. 7, but in this case as well, the upper part of the bag is packed to pack the outer bag b. When it is bent, the seal part d is cracked along the perforation notch g, and if this crack goes inside, it will become a pin hole, and eventually the chemical in the chemical filling container a will be oxidized. Absent.

[0005]

[Means for Solving the Problems]

 The present invention prevents injuries such as fingertips due to the notch when handling the outer bag, and also prevents the bag from breaking inward even if the bag is broken at the notch and the seal part is cracked, and is stored. The problem was to provide an outer bag that does not impair the barrier properties inside, and the perforation or slit-like notch for opening that is provided on the outer peripheral seal of the bag is notched when not opened. An overhanging seal part is provided inside the outer peripheral seal part on the extension of the notch to prevent the crack from propagating in the entire area of the seal width by breaking at the part, and between the outer peripheral seal part and the overhanging seal part. Overhanging is to form a non-sealed part surrounded by the sealed part. Further, instead of the unsealed portion, a mountain-shaped cut is provided at the inner end of the notch, and the notch has an arrow shape.

As a result, even if the outer peripheral seal portion bends at the notch and cracks occur along the notch, the cracks will surely stop at the non-sealed portion or the mountain-shaped notch and proceed beyond the outer peripheral seal portion. It can be prevented.

[0007]

[Embodiment of device]

 Hereinafter, the present invention will be described with reference to the embodiments shown in the drawings.

FIG. 1 shows a front view of an outer bag 1 according to the present invention, which is made of a composite nylon film having a gas barrier property and has a thickness of about 100 to 150 μ. Is in formation. Peripheral seal portions 1a having a constant width are continuously provided on the left and right sides and the lower side of the outer bag 1. At the upper left and right positions of the outer peripheral seal portion 1a, as shown by P, perforation notches 1b and 1b for opening extend from the outer end toward the inner side, respectively, for about half the width of the outer peripheral seal portion 1a. It is provided.

FIG. 2 is an enlarged view of a portion P of FIG. 1, which is a substantially semi-annular shape having a center on an extension line of the perforation notch 1b of the outer peripheral seal portion 1a provided around the outer bag 1. The protruding seal portion 1c is formed, and the semicircular seal-free portion 1d is formed on the extension line of the perforation. As a result, both ends of the overhanging seal portion 1c formed in a semi-annular shape are in contact with the outer peripheral seal portion 1a and are connected to the outer peripheral seal portion 1a.

Although the non-sealing portion 1d has a semicircular shape in the embodiment shown in FIG. 2, it is not limited to this and may have a quadrangular shape or the like.

Therefore, regarding the notch of the perforation, the outer bag 1 is not opened yet, for example, when the outer peripheral sealing portion 1a is folded at the notch portion 1b of the perforation when the bag is in a stored state, a crack generated from the perforation is sealed. Even if the crack progresses over the entire width, the crack stops at the outer peripheral seal portion 1a to the non-sealed portion 1d. Therefore, the outer bag 1 can be kept unopened by the overhanging seal portion 1c. At the time of opening, the perforation notch portion 1b is forcibly torn up and down, but at this time, the protruding seal portion 1c can also be easily broken.

FIG. 3 shows another embodiment of the present invention, in which a mountain-shaped cut 2 is formed in the outer peripheral seal portion 1a at the inner end position of the notch 1b of the perforation which is inserted in the outer peripheral seal portion 1a. A notch 1b is formed in the shape of an arrow.

Therefore, even if the outer peripheral seal portion 1a is broken at the notch 1b portion and a crack is generated, the progress of the crack is stopped by the ridge-shaped cut 2 and does not extend to the entire width of the outer peripheral seal portion 1a. At the time of opening, the notch 1b can be easily opened by tearing through the notch 2.

The unsealed portion 1d may be combined with the arrow-shaped notch 1b.

[0015]

[Effect of device]

 As described above, according to the present invention, even when the notch portion is bent at the time of handling or storing and a crack is formed along the notch, the crack does not reach the inside of the outer bag, and thus the outer bag is provided. The barrier property can be maintained without impairing the function as. In addition, since the notch can be a linear one such as perforations, it is safe without damaging the fingers during handling.
