Abstract

(57) [Summary] [Purpose] A bacterial test bag can be leaned against with a sample suspension inside. [Structure] In a bag for bacteria inspection, the bottom of the bag is formed into a bag bottom that spreads in the horizontal direction.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a bag used in a bacteria test of foods and the like.

[0002]

[Prior Art]

 In the case of bacterial inspection of food, usually, an appropriate amount of sample and diluent are placed in a bag made of polypropylene or the like, and the bag is hung on a machine such as a homogenizer and pressurized for a predetermined time, so that the sample in the bag is suspended. It is practiced to make a suspension, collect an appropriate amount of the suspension, and send it for inspection. As shown in FIG. 3, the above-mentioned bag for bacteria inspection has a bag bottom 4 in which two bag materials 1 and 2 that have been polymerized are provided with bottom seals 3 from both sides thereof, and the bag materials 1 and 2 are directly adhered to each other. Was used.

[0003]

[Problems to be solved by the device]

 With the conventional bag for bacteria test described above, even if you want to lean the bags individually with the sample suspended in them, the bottom of the bag does not spread horizontally, so you cannot lean it. However, it takes time and effort to collect the suspension from the bag, which reduces the efficiency of the bacterial test. Therefore, if you use a dedicated stand, you can lean the bags individually, but then you have to secure a place to store the dedicated stand when not in use, and when the number of samples is large, There was a problem that the number of dedicated stands kept was insufficient. An object of the present invention is to provide a bag for testing bacteria which can solve the above-mentioned conventional problems.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is characterized in that in a bag for bacteria inspection, a bag bottom that spreads in the horizontal direction is formed at the bottom of the bag body.

[0005]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. Reference numeral 5 denotes a filter bag body formed by using a bag material such as polypropylene so as to have a bag bottom 6 extending in the horizontal direction. One bag material is folded back to form the side portions 7 and 8 of the bag body 5, and the folded end portion 9 of the bag material is folded between the side portions 7 and 8 to form a bag bottom 6 that spreads horizontally. Then, the side edge seals 10 and 11 along both side edges of the side surface portions 7 and 8, the bottom side seal 12 along the lower side of the side surface portion 7 and one side edge of the bag bottom 6, and the lower side of the side surface portion 8 and the bag A bag made by applying a bottom seal 13 along the other side edge of the bottom 6 is used. Reference numeral 14 denotes a filter bag attached to one side of the bag body 5, which is attached using a side edge seal 10 from a position of the bag body 5 which is close to the bag mouth 15 to a position which is close to the bag bottom 6. 16 and 17 are liquid leakage preventing chucks formed along the edge of the bag mouth 15.

In the bacterial test bag having the above configuration, when the bag body 5 is placed on an inspection table or the like with the sample suspension contained therein, the bag bottom 6 is pressed by the suspension. The bottom seals 12 and 13 are supported by the support frame while being expanded in a horizontal direction, and the bottom seals 12 and 13 expand in an annular shape to support the bag body 5 in an upright state. When the suspension is collected from the bag body 5 thus supported, the chucks 16 and 17 are disengaged, the bag mouth 15 is opened, and the collection tool is inserted into the filter bag 14. The residue contained in the suspension is collected by filtration.

[0007]

[Effect of the device]

 Since the present invention is configured as described above, it is possible to lean the bags individually while the sample suspension is contained, so it takes time to collect the suspension from the bag. In addition, the work efficiency of the bacteria test can be improved accordingly. Also, since it is not necessary to use a dedicated stand, there is an advantage that there is no need to secure a place for storing the dedicated stand when not in use.
