Description

  The present invention relates to an extension stick of a wiping test kit used for microbial testing.

  It is extremely important to evaluate cleanliness in order to avoid nosocomial infections in medical facilities such as hospitals and food poisoning due to contamination in cooking utensils and food processing facilities. There is a cleanliness test to check whether fingers, equipment, food processing facilities, medical facilities, etc. are kept clean, and there is a wiping culture method as one of the measuring methods. This is a method of wiping a predetermined area of an inspection object with a cotton swab or the like, suspending it in a diluent, and culturing microorganisms contained in the diluent on an agar medium or a film medium. The number of microorganisms contained in the diluted solution can be measured and the microorganism species can be specified.

  In order to easily perform the wiping culture method, a wiping test kit has been developed that can prepare a diluent and drop a predetermined amount of the diluent onto the medium (Patent Document 1). The kit described in Patent Document 1 includes a container main body for storing a diluent and a hinge cap to which a cotton swab shaft is fixed, and the diluent is discharged from the inside of the container to the lower screw-type cap constituting the hinge cap. This is a wiping inspection kit equipped with a stopper cap for forming a liquid passage to be closed and liquid-tightly closing the upper end opening of the liquid passage. Open the hinge cap and wipe off the object to be inspected with the swab shaft fixed to the spiral cap. Next, the hinge cap is attached to the container body, and the microorganisms adhering to the swab shaft are diluted with a diluent stored in the container body. Thereafter, the container is turned upside down, the upper cover of the screwed hinge cap is opened, and the diluted solution is taken out from the liquid passage provided in the screwed cap. If a hinge cap having a liquid passage is used, a medium of a certain amount can be inoculated without using a pipette by referring to the memory formed in the container body.

  The length of the swab shaft depends on the length of the container body and is usually about 10 cm. In some cases, the object to be inspected is difficult to wipe with a 10 cm swab shaft such as a food or other production line. In view of the fact that wiping is not easy with only a cotton swab shaft fixed to the cap, there is a wiping inspection kit in which an extension rod coupled to the cap with a reverse screw is detachably disposed (Patent Document 2). A cylindrical cap is formed with a closing surface, a thread that is screwed to the container main body is formed at the bottom of the cap, and a reverse thread that can be screwed to the extension rod is formed at the top of the closing surface. Since each screw thread is formed so that the turning direction when attaching the extension rod to the cap and the turning direction when removing the cap from the container body are the same direction, the extension rod continues to turn in a predetermined direction. The extension bar can be attached to the cap, and the cap can be subsequently removed from the container body.

  On the other hand, Patent Document 1 also describes that a swab shaft can be telescopically extended. The shape of the container main body used in the wiping inspection kit is a flat surface in which the side surface of the intermediate portion is recessed inward as shown in Patent Document 1 and FIG. This is because when the surface to be inspected is wiped off with a cotton swab shaft, the cotton ball is compressed from the side surface of the container body, and excess diluted liquid adhering to the cotton ball is squeezed out. The telescope can be stretched simultaneously when the cotton ball is compressed.

JP 2003-344232 A JP 2008-101971 A

  The material of the container main body of the wiping inspection kit is made of a soft resin such as low-density polyethylene so that the above-described cotton ball can be easily compressed. However, there is a limit to the flexibility of the container in order to ensure quantitativeness and shape retention at the time of discharging the diluted solution, and there are some inspectors who do not have sufficient pressing force for the telescope drawing operation. Further, at the time of wiping, the telescope may contract due to the wiping pressure. If the telescope pull-out operation is not required prior to the wiping operation, a faster operation can be performed.

  Moreover, if the shape of the container main body is extended in the longitudinal direction, a long swab shaft can be secured. However, if the container opening has a small diameter, the efficiency at the time of filling the container body with the diluent decreases at the time of manufacture, and there is a limit to the shape of the container body in consideration of the mode of use. Therefore, it is desired to develop a wiping inspection kit that can extend the swab shaft with a simple operation without reducing the production efficiency.

  In particular, the wiping inspection kit described in Patent Document 1 has a dispensing function capable of discharging a predetermined amount of diluent from the helical cap when the upper cover of the hinge cap is removed after the wiping operation. As described above, the wiping inspection kit described in Patent Document 2 discloses an extension bar that is screwed to the cap attached to the container body with a reverse screw, but the upper cover of the wiping inspection kit having a dispensing function has a stopper function. It is necessary to hold, and it is difficult to form a reverse screw portion on the upper lid. Therefore, it is desirable to develop a kit that can extend the swab shaft without impairing the dispensing function.

  In view of the above-described present situation, an object of the present invention is to provide an extension stick that can be attached to a lid portion of a wiping inspection kit and can be easily attached and detached.

  As a result of examining the wiping inspection kit in detail, the present inventors formed irregularities on the top surface portion of the lid portion and processed the tip of the extension stick into a shape that fits the irregularities, thereby pressing the extension stick against the lid portion. The lid can be opened and closed by rotating the extension stick afterwards, and the lid can be screwed onto the container body by rotating the extension stick after wiping the surface to be inspected. It was found that the extension stick could be removed very easily by pulling it out after that, and the present invention was completed.

The present invention is an extension stick that is detachably fixed to the lid by pressing and / or fitting,
An extension stick is provided that includes a coupling portion that includes a top surface portion and a side surface portion, and is fitted or locked to the lid portion, and a gripping portion that is coupled to the coupling portion.

  Further, according to the present invention, the top surface of the coupling part is formed with a convex part and / or a concave part for coupling with the grip part, and the grip part fits and locks the convex part and / or the concave part. Alternatively, the extension stick is provided in which a concave portion, a convex portion, and / or a notch passing therethrough is formed.

Further, the present invention is an extension stick including two or more of the grip portions,
The grip part is formed with a convex part and / or a concave part for coupling with another grip part,
The other gripping part provides the extension stick, wherein a concave part and / or a convex part for fitting and / or locking the convex part and / or the concave part is formed.

In addition, the present invention is a hinge cap, wherein the lid portion has a hinge protruding outward from the top surface,
The extension stick is provided in which a notch passing through the protruding hinge is formed on the side surface of the joint, and the notch serves as a locking portion for locking the hinge.

  In the wiping inspection kit of the present invention, the extension stick can be attached and detached through the unevenness formed on the top surface of the lid. When the extension stick grip is rotated counterclockwise after the extension stick is connected to the lid, the screw connection between the container body and the lid can be released and the swab shaft can be removed from the container body. The extension stick can be easily recovered by wiping the surface to be inspected, storing the swab shaft in the container body, rotating it clockwise, and then pulling out the extension stick.

  In addition, the extension stick of the present invention can be easily attached to the lid portion of the wiping inspection member, and a plurality of the extension sticks can be connected to each other to extend the length of the wiping inspection member.

The recess C13 is formed. When the extension stick C is pushed into the lid B of the wiping inspection member so that the projection B49 and the recess C13 are fitted, the projection B49 of the stopper cap B40 and the recess C13 of the extension stick C are fitted. The wipe inspection member and the extension stick C are combined. In FIG. 4, the projection B49 is formed in the stopper cap B40 and the recess C13 is formed in the coupling portion C10. However, the recess corresponding to the coupling cap C10 is formed in the stopper cap B40. A part can also be formed. The shape and number of the convex portions and the concave portions are not particularly limited as long as the lid portion B and the coupling portion C10 of the extension stick C can be coupled by pressing or fitting.

  In the embodiment shown in FIG. 4, the projection B49 formed on the top surface portion B41 of the stopper cap B40 and the recess C13 formed on the top surface portion C11 of the coupling portion C10 and the side surface portion B21 of the screw-on cap B20 are fitted. The lid portion B and the coupling portion C10 are engaged with each other by the engagement between the opening / closing knob portion B47 formed on the side surface portion B43 of the formed hinge B30 and the stopper cap B40 and the notch portion C15 formed on the side surface portion C12 of the coupling portion C10. It is to be combined. However, in the case of a hinge cap in which the hinge B30 does not protrude from the side surface portion B21 of the screw-on cap B20 and the opening / closing knob portion B47 does not exist, it is not necessary to form the corresponding notch portion C15. It can be coupled to the coupling portion C10 by fitting with a concave portion and / or a convex portion formed in the stopper cap B40. However, a cutout portion C15 or a cut may be formed in the side surface portion C12 of the coupling portion C10 regardless of the presence or absence of the hinge B30 and the opening / closing knob portion B47. At this time, the inner diameter φC of the bottom portion of the coupling portion C10 may be the same as or slightly shorter than the outer diameter φB of the bottom portion of the screw cap B20. The side part B21 of the screw cap B20 is pressed toward the center by the side part C12 of the coupling part C10, and the coupling between the lid part B and the extension stick C can be made more stable.

  When the above-described hinge cap is used, the swab shaft B5 from which the surface to be inspected is wiped is impregnated with the diluent A7 to suspend the adhering microorganisms, and then the container body A is turned upside down to form a screw-on cap B20. The diluent A7 can be discharged from the liquid passage B25. This aspect will be described with reference to FIG. FIG. 5A is a cross-sectional view of a wiping inspection member in which a lid portion B having a convex portion B49 formed on the outer side of the top surface portion B41 of the stopper cap B40 is screwed to the container main body A.
