Description

The present invention relates to a wiping inspection kit that is particularly suitably used for inspecting that instruments and equipment used for food processing are clean and hygienic.

As part of food safety testing, product inspection, raw material inspection, hand inspection of production personnel, process inspection or whether equipment and equipment used in restaurants, kitchen facilities, etc. are clean and hygienic in general, It is evaluated by examining the number of viable bacteria and coliforms, and in some cases, further examinations such as Staphylococcus aureus, fungi, and yeast are performed.

Equipment, equipment, containers and packaging to be inspected have various different shapes, and the wash-off method is usually used to inspect the contamination inside bottled containers such as bottles and cans. In cases where the surface of a cutting board, a dish or the like is a flat instrument or an instrument having an irregular shape such as a kitchen knife, a sample test solution is prepared in accordance with the wiping inspection method.

The wiping inspection method uses a gauze tampon or cotton swab / cotton ball, etc. that has been sterilized by damaging 1 ml of 0.1% peptone-added physiological saline, and then wiping the surface of the device or equipment to be inspected. It was a conventional method to dilute by adding 9 ml of sterilized 0.1% peptone-added physiological saline and homogenize the sample to prepare a sample test solution. It was difficult to conduct an accurate inspection in a general kitchen facility without a laboratory.

Further, the wiping test as described above is also performed clinically in order to collect a specimen by wiping affected areas such as throat, nose and ears with a cotton swab or a cotton ball. Conventionally, the sample collected by wiping and collecting the sample collected by wiping with a cotton swab etc. was dipped in a phosphate buffer solution or the like dispensed in a test tube, and then pressed against the side wall of the test tube and rotated. It was extremely troublesome and skillful.

In view of such circumstances, the present applicant has developed a wiping inspection kit that can easily and reliably perform wiping inspection even in a facility that does not have a laboratory (Patent Document 1). According to this wiping test kit, when dispensing the sample contained in the container body together with the diluent into a culture medium such as a petri dish for quantitative test, the sample is opened by opening the top cover with the cap attached. Since it can discharge | emit, there exists an advantage which can perform a dispensing operation | work easily, The usefulness is highly evaluated also in the market.

JP 2003-344232 A

However, the wiping inspection kit according to Patent Document 1 has room for further improvement. In other words, if the upper lid of the wiping inspection kit is accidentally opened, the content liquid may leak out. For example, when this wiping inspection kit is transported by air in a state where it is horizontally stacked in an aircraft cargo compartment, the upper lid opens due to the influence of atmospheric pressure fluctuation, and the liquid content may leak from the tip of the cap.

Therefore, an object of the present invention is to provide a wiping inspection container having a novel configuration capable of preventing the above-described accident that may be encountered by the wiping inspection kit according to Patent Document 1. More specifically, in the same manner as the wiping test kit according to Patent Document 1, when dispensing into a medium such as a petri dish for quantitative inspection, the sample is discharged by opening the top lid while the cap is still attached. The task is to ensure that the liquid contents can be prevented from leaking even if the top lid is opened in the transport stage before use, etc., after ensuring the ease of the work.

In order to solve this problem, the present invention according to claim 1 is directed to a container body that contains a diluent, a cap that is detachably attached to an opening of the container body, and a cotton swab that is attached to the cap and extends downward. A cotton ball that is attached to the tip of a cotton swab and is immersed in a diluent in the container body in a cap-sealed state, an upper lid that is provided with a lower protrusion that is inserted into an opening on the upper surface of the cap, and that can be opened and closed, and a container body A wiping inspection kit having a liquid passage for allowing the content liquid inside to pass through the cap opening and a liquid sealing film provided at a predetermined height in the cap opening, when the upper lid is pressed from above and recessed. The content liquid in the container body is passed through the liquid passage from the liquid passage to the cap opening by piercing the liquid sealing film at the tip of the lower protrusion, and the content liquid can be discharged from the cap opening to the outside when the upper lid is opened. It is configured to a test kit wiping characterized.

According to a second aspect of the present invention, in the wiping inspection kit according to the first aspect, a thin portion is provided on the top surface of the upper lid, and when the top surface of the upper lid is pressed from above, the top of the upper lid is interposed via the thin portion. The surface is deformed downward, and the liquid sealing film is pierced by the tip of the lower protrusion.

According to a third aspect of the present invention, in the wiping inspection kit according to the second aspect, the thin portion is formed in a substantially ring shape on the top surface of the upper lid so as to surround the lower protrusion.

According to a fourth aspect of the present invention, in the wiping inspection kit according to any one of the first to third aspects, when the top surface of the upper lid is depressed from above, the lower projection fits into the cap opening. The surface is maintained in a recessed state, and it is possible to identify that the liquid sealing film has been opened by visually confirming the recessed state.

The present invention according to claim 5 is characterized in that the lower protrusion of the upper lid has an oblique cylindrical shape obtained by obliquely cutting the lower end of the substantially cylindrical shape.

According to the first aspect of the present invention, since the liquid sealing film is provided at a predetermined height position in the cap opening, as long as the liquid sealing film is held as it is, the content liquid in the container body passes through the liquid passage. Even if it tries to enter the cap opening, the liquid sealing film prevents further liquid passage. Therefore, even if the upper lid is opened in this state, the content liquid does not leak from the opening on the upper surface of the cap. Since the wiping inspection kit of the present invention is supplied to the user in this state, the content liquid (diluted) from the tip of the cap can be obtained even if it is affected by atmospheric pressure fluctuations during air transportation in the state of being stacked horizontally in the cargo compartment of the aircraft. Liquid) can be prevented from leaking out. In addition, the liquid seal film is retained even if the upper lid is accidentally opened when the sample wiped with the cotton ball of the wipe test kit is stored in the container body and mixed. As long as there is no liquid leakage.

Thereafter, when dispensing into a medium such as a petri dish for quantitative inspection, the upper lid is pressed from above to be recessed, and the cap opening is passed through the liquid passage by breaking through the liquid sealing film at the tip of the lower protrusion. As a result, the inside and outside of the container body allow fluid to pass through the liquid passage and the cap opening, so that the specimen can be discharged by opening the top cover while the cap is attached, and at the time of quantitative inspection Can be easily dispensed.

In addition, when injecting an enrichment medium for qualitative testing, the upper lid is pressed from above to be recessed, and the top of the lower protrusion penetrates the liquid sealing film to allow liquid to pass through. It is possible to store the qualitative test medium injected with a dropper from the container into the container body through the liquid passage, and the medium injection work during the qualitative test can be easily performed.

According to the second aspect of the present invention, since the top cover top surface is formed into a shape that is easily deformable by providing a thin portion on the top cover top surface, the operation at the time of breaking through the liquid seal film with the tip of the lower protrusion is performed. It can be done easily.

According to the third aspect of the present invention, since the thin portion is provided in a substantially ring shape on the top surface of the upper lid, the top surface of the upper lid becomes a more easily deformable shape, and when the liquid sealing film is pierced by the tip of the lower protrusion The operation can be performed more easily.

According to the fourth aspect of the present invention, the liquid sealing film is held in an unopened state (unused state) by visually confirming the presence or absence of the recessed state of the upper lid top surface, or the liquid sealing film There is an effect that it is possible to easily determine whether or not is already opened.

According to the present invention of claim 5, since the lower projection of the upper lid has a slanted cylindrical shape, when the upper lid is depressed from above, the most distal portion of the lower projection is the liquid sealing film first. Since the liquid sealing film is gradually broken at the edges on both sides thereof, the liquid sealing film can be smoothly broken with a relatively small force. If the lower protrusion of the upper lid has a simple cylindrical shape, the lower edge of the upper lid reaches the liquid seal film at the same time, so the liquid seal film is broken into a circle at once, and the fragments fall and fall inside the container body. Although there is a risk of becoming a noise with respect to the content liquid, it is possible to prevent such a risk by adopting a slanted cylindrical shape.

It is the front view (a) and side view (b) of the wiping inspection kit by one Embodiment of this invention. It is a perspective view of the surface view which shows the cap with an upper cover in this wiping test | inspection kit in the state which opened the upper cover. It is a perspective view of the back view of the same state as FIG. It is a centerline fracture | rupture perspective view which shows a cap with an upper cover in the state which closed the upper cover. It is an expanded sectional view of the principal part in FIG.

FIG. 1 is a front view (a) and a side view (b) of a wiping inspection kit 10 according to an embodiment of the present invention, and a container body 20 integrally formed of a soft material that can be compressed and deformed, such as high-density polyethylene, A cap 30 that is detachably mounted to seal the upper end opening of the container body 20, a cotton swab 42 that is fixed to the cap 30 and includes a cotton ball 41 at the tip, and an upper lid 50 that is connected to the cap 30. It is configured.

As a means for detachably attaching the cap 30 to the upper end of the container main body 20, it can be easily attached / detached by hand, such as a screw-in type or a push-in type, and the inside of the container is substantially completely airtight when sealed. Any detachable structure that maintains liquid tightness can be employed. In the present embodiment, a screw thread (not shown) is formed in a spiral shape on the outer periphery of the upper end opening 11 of the container body 20, and a screw thread 31 that can be screwed to the male screw is formed in a spiral shape on the inner periphery of the cap 30. Thus, the cap 30 can be attached to and detached from the upper end of the container main body 20.

The cotton swab 41 is a solid or hollow rod formed of a material such as polypropylene, and is attached to the center of the back surface of the cap 30 by screwing, bonding, or any other means, and extends downward. In this embodiment, a hollow cylindrical portion 32 is integrally formed at the center of the back surface of the cap 30, and the upper end of a hollow cotton swab 42 is inserted into the lower end of the hollow cylindrical portion 32 so as to be detachably attached (FIG. 2), the swab 42 may be fixed to the cap 30 or may be formed integrally with the cap 30.

A predetermined amount (for example, 10 ml) of diluent 21 is stored in the container body 20 in advance. As the diluent 21, for example, 0.1% peptone-added physiological saline, buffered peptone water, phosphate buffered physiological saline, or the like is used. The cotton ball 41 held at the lower end of the cotton swab 42 is higher than the liquid level 22 of the diluent 21 stored in advance in the container body 20 in a state where the wipe inspection kit 10 is held with the cap 30 up. It is located below and is thus kept immersed in the diluent 21.

The container main body 20 has a substantially cylindrical shape, but the middle portion thereof is narrowed down to form the reduced diameter portion 23. The reduced diameter portion 23 in this embodiment is shown as having a pair of opposed surfaces, and the distance between these surfaces (the inner dimension of the reduced diameter portion 23) is set slightly larger than the outer diameter of the cotton ball 41. Has been.

Further, a scale 24 is displayed on the side surface of the container main body 20 constituting the reduced diameter portion 23 (FIG. 1B). As will be described later, the scale 24 is used for confirming the amount dispensed when the wiping test kit 10 is inverted from the state shown in FIG. 1 and dispensed into a predetermined test container such as a petri dish containing medium. Since it is used for the above, it is displayed so that it can be easily seen in an inverted state. Since 10 ml of the diluted solution is stored in the container body 20 in advance, the liquid level of the content solution (diluted sample) is almost coincident with the scale of “10” when the container body 20 is inverted. As the process continues, the liquid level decreases. At that time, a necessary amount can be dispensed by referring to the scale 24.

2 to 5 show configurations related to the cap 30 and the upper lid 50 of the wiping inspection kit 10 according to one embodiment of the present invention (both are not shown). The cap 30 includes an outer cylindrical portion 33 having a substantially cylindrical shape in which a thread 31 that can be screwed to an outer peripheral thread of the upper end opening of the container body 20 is formed on the inner periphery, an upper surface 34 having a central opening 35, an upper surface 34 has a configuration in which the hollow cylindrical portion 32 protruding downward from the central back surface side is integrally formed. The central opening 35 of the cap upper surface 34 communicates with the hollow portion of the hollow cylindrical portion 32.

The upper lid 50 is connected to the cap 30 via a hinge 51 so as to be openable and closable. When the upper lid 50 is in an open state (FIGS. 2 and 3), the opening 35 communicates with the outside, but when it is closed (FIG. 4). The lower projection 52 enters the opening 35 from the enlarged diameter opening end 36 of the cap upper surface 34 and seals it, thereby closing the opening 35 in an airtight and liquid tight manner.

The inner diameter of the hollow cylindrical portion 32 of the cap 30 is set slightly larger than the outer diameter of the cotton swab 42. A plurality of protrusions 37 extending in the axial direction at intervals are formed on the inner peripheral surface of the hollow cylindrical portion 32 so as to surround the cotton swab 42. In the illustrated embodiment, five protrusions 37 are formed at equiangular intervals, and the upper ends of these protrusions 37 protrude inward to form inward protrusions (not shown in FIGS. 4 and 5) . The swab 42 is detachably attached to the hollow cylindrical portion 32 with its upper end locked to the inward projection and fitted between the protrusions 37.

With the cap configuration as described above, when the cap 30 is attached to the upper end opening of the container body 20 and sealed, the internal space of the container body 20 (initially containing a predetermined amount of diluent 21) is The gap 37 between the cap hollow cylindrical portion 32 and the cotton swab 42 is communicated with the opening 35 of the cap upper surface 34 through a gap (an axial gap 38 formed between the ribs 37) where the protrusion 37 does not exist. . That is, the content liquid in the container body 20 can enter the opening 35 of the cap upper surface 34 through the gap 38, and this gap 38 functions as the “liquid passage” of the present invention.

Further, since the cotton swab 42 in this embodiment is hollow, the liquid in the container body 20 can enter the internal space from the lower end of the cotton swab 42 through the sponge cotton ball 41. The internal space of the cotton swab 42 communicates with the opening 35 of the cap upper surface 34 through a gap 39 formed between the upper end of the cotton swab 42 and the bottom surface of the hollow cylindrical portion 32 by the inward projection . In other words, the liquid in the container main body 20 can enter the opening 35 of the cap upper surface 34 through the internal space of the cotton swab 42 and the gap 39, and the hollow internal space of the cotton swab 42 is coupled with the gap 39. It works as a “passage”.

These “liquid passages” are exemplary and not limiting. As long as the liquid contained in the container body 20 can flow into the opening 35 of the cap upper surface 34, any specific mode can constitute the “liquid passage”. In the illustrated embodiment, when the swab 42 is formed solid, the “liquid passage” is formed only by the gap 38, but such an embodiment is also within the scope of the present invention.

A thin portion 54 is formed in a substantially ring shape on the top surface 53 of the upper lid 50 except for a portion that interferes with the hinge 51. The thin portion 54 is formed so as to surround the lower protrusion 52 that protrudes downward from the top surface 53 of the upper lid 50, and on the opposite side of the hinge 51 (the side on which the protruding piece 55 is formed), a large groove reaching the periphery. It is supposed to have a width. As a result, when the central portion of the top surface 53 of the upper lid 50 in the closed state ( FIG. 4 ) is pressed from above with a thumb or the like (see FIG. 5) , the upper lid top surface 53 is greatly recessed, and the lower protrusion 52 is formed. It is easy to insert into the cap opening 35.

A liquid sealing film 40 is provided at a predetermined height position of the cap opening 35. The liquid sealing film 40 does not reach the lower protrusion 52 of the upper lid 50 when a downward pressing force is not acting on the top surface 53 of the upper lid 50 in the closed state (FIG. 4). When the center portion is pressed from above with a thumb or the like and the lower protrusion 52 is inserted into the cap opening 35 (see FIG. 5) (see FIG. 5) , the tip thereof is provided at a height position that can break through the liquid sealing film 40. ing. The liquid sealing film 40 is sufficient to be held without being ruptured or damaged when the pressing force is not acting on the top surface 53 of the upper lid 50 in the closed state ( FIG. 4 ) . When a pressing force is applied to the surface 53 and the lower protrusion 52 is inserted into the cap opening 35, the material, film thickness, etc. are selected and used so as to have a strength that can easily be ruptured or damaged at the tip.

The wiping inspection kit 10 is sterilized by autoclaving or radiation in a state in which a predetermined amount of diluent 21 is stored in a container body 20 and sealed with a cap 30, and is stored, transported and marketed as a sterilized one. At this time, the liquid sealing film 40 is provided at a predetermined height position in the cap opening 35, and the diluent 21 in the container body 20 enters the cap opening 35 through the hollow cotton swab 42 and the gaps 38 and 39. However, the liquid sealing film 40 prevents further liquid passage. Therefore, even when the upper lid is opened due to the influence of atmospheric pressure during air transportation in the state of being stacked horizontally in the cargo compartment of the aircraft, the diluent 21 does not leak from the cap opening end 36.

The wiping inspection performed using the wiping inspection kit 10 having the above-described configuration can be performed in the same manner as described in Patent Document 1.

That is, the wiping inspection kit 10 is opened with the cap 30 facing upward (with the cap 30 facing up), and the cap 30 is pulled upward. The cotton swab 42 and the cotton ball 41 at the tip thereof are also pulled out together with the cap 30, and the cotton ball 41 immersed in the diluent 21 is pulled up above the liquid level 22 of the diluent.

Further, the cap 30 is raised, and when the cotton ball 41 passes through the reduced diameter portion 23 of the container body 20, the opposing surface of the reduced diameter portion 23 is lightly compressed with a finger from the outside. As described above, the container body 20 is integrally formed of a soft material that can be compressed and deformed, such as high-density polyethylene. Therefore, the container body 20 is easily compressed and deformed by applying a slight force with a finger. As a result, the inner size of the reduced diameter portion 23 is reduced to be slightly smaller than the outer diameter of the cotton ball 41, a squeezing force is applied to the outer peripheral portion of the cotton ball 41, and the dilution liquid 21 adhering to the cotton ball 41 is reduced. Remove excess.

According to another embodiment, the inner size of the reduced diameter portion 23 is set to be slightly smaller than the outer diameter of the cotton ball 41 from the beginning, and the cotton ball 41 passes through the reduced diameter portion 23 when opened. At this time, a squeezing force is automatically applied to the outer peripheral portion of the cotton ball 41, and an excess of the diluent 21 adhering to the cotton ball 41 is removed. According to this embodiment, it is possible to remove the excess portion of the diluent 21 adhering to the cotton ball 41 without having to compress the reduced diameter portion 23 with a human finger.

The specimen surface is wiped off using the cotton ball 41 from which the excess diluent 21 has been squeezed out as described above. Since the cotton ball 41 is fixed to or integrated with the cap 30, the wiping operation can be performed easily and without damaging the sterilized state of the cotton ball 41 by gripping the outer cylinder portion 33 of the cap 30 with a human finger. And there is no need to use tweezers.

After the sample surface is wiped off using the cotton ball 41, it is accommodated in the container body 20 again and sealed with the cap 30. The cotton ball 41 to which the bacteria on the specimen surface are attached is re-immersed in the diluent 21 by a tight stopper and mixed by shaking in the horizontal direction, etc., so that the specimen 20 is diluted as a specimen at a predetermined dilution rate. Is housed in. Preferably, the sample can be collected efficiently by repeating this operation a plurality of times.

Even at this time, the liquid sealing film 40 provided at a predetermined height position in the cap opening 35 remains without being ruptured or damaged (this is to visually confirm that the top lid top surface 53 is not recessed). Therefore, even if the content liquid of the container body 20 (the sample stock solution diluted at a predetermined dilution rate) enters the cap opening 35 via the hollow cotton swab 42 or the gaps 38 and 39, the liquid seal The membrane 40 prevents further liquid passage. Therefore, even if the upper lid is accidentally opened during pouring or the like, the content liquid does not leak from the cap opening end 36.

A predetermined amount of this sample stock solution is dispensed and cultured in a laboratory container such as a petri dish or test tube containing medium, and microbiological examination (quantitative examination) such as the number of viable bacteria and coliforms is performed. This dispensing operation will be described. .

When the central portion of the top lid top surface 53 is pressed from above with the thumb or the like while the upper lid 50 of the wiping inspection kit 10 containing the sample stock solution is sealed, the lower projection 52 is formed on the cap opening 35. At the tip, the liquid sealing film 40 provided at the cap opening 35 and blocking liquid flow is pierced and broken (shown by phantom lines in FIG. 5). Thereby, the cap opening 35 is in fluid communication with the hollow cylindrical portion 32. At this time, since the lower projection 52 is in close contact with and fitted into the inner surface of the cap opening 35, the top lid top surface 53 is maintained in a recessed state. By visually confirming this recessed state, this It can be easily determined that the wiping inspection kit 10 has been opened.

And the upper cover 50 is opened and the wiping inspection kit 10 is turned upside down. Since the cap opening 35 is completely passed due to the breakage of the liquid sealing film 40, the sample stock solution contained in the container body 20 passes through the cap opening 35 from the liquid passage (the hollow interior of the gap 38, the gap 39, and the cotton swab 42). Then, it is dropped from the cap opening edge 36.

In dispensing work into a test container such as a petri dish, a necessary amount can be dispensed with reference to the scale 24 displayed on the side surface of the container body 20, so that the sample stock solution can be directly applied to a petri dish or the like without a pipette. An accurate dispensing amount can be dropped.

In the case where the wiping test kit 10 is used as it is as a culture container to perform a qualitative test, the liquid sealing film 40 is broken by pressing the center of the top surface 52 of the upper lid with a thumb or the like in the same manner as described above. Then, the upper lid 50 is opened, a tip such as a dropper is inserted into the cap opening 35, and a medium for qualitative examination is injected. Since the cap opening 35 has already been completely passed due to the destruction of the liquid sealing film 40, the medium injected from the cap opening 35 passes through the liquid passage (the void 38, the void 39, the hollow interior of the cotton swab 42), and the container together with the sample stock solution. It is accommodated in the main body 20. Thereafter, the upper lid 50 is closed, mixed by shaking in the horizontal direction, etc., cultured for a predetermined time (for example, 24 hours), and the presence of coliforms is inspected qualitatively by discoloration or the like.

Although one embodiment of the present invention has been described above, the present invention is not limited to this, and can be variously modified within the scope of the invention described in each of the claims.

For example, as a structure for pressing the upper lid 50 from above to break the liquid sealing film 40, in the illustrated embodiment, a thin portion 54 is formed in a substantially ring shape except for a portion that interferes with the hinge 51, and the center of the upper lid is formed. The center part of the upper lid is recessed downward when the part is pressed with a thumb or the like, and the lower protrusion 52 is inserted into the cap opening 35 to break through the liquid sealing film 40, but the upper lid top surface 53 is greatly deformed. A structure that performs the same action when pressed with a thumb or the like by forming it with a soft material that can be used may be adopted.

In the illustrated embodiment, a hollow cotton swab is used, but a cotton swab configured as a solid rod body may be used. Further, when a hollow cotton swab is used, a plurality of small holes (which also constitute a “liquid passage”) communicating with the hollow interior may be formed in the wall portion.

Moreover, it is good also as a telescope type telescopic structure using the hollow structure of a cotton swab. The cotton swab having such a stretchable structure is housed in the container body in a contracted state, and can be easily wiped away by being stretched during use, so that it is highly convenient. .

The shape of the lower protrusion 52 of the upper lid 50 is not particularly limited as long as it can rupture or break the liquid sealing film 40 in the cap opening 35 when the upper lid top surface 53 is pressed and recessed. However, it preferably has a slanted cylindrical shape obtained by obliquely cutting the bottom end of a substantially cylindrical shape as in the illustrated embodiment. By adopting such a shape, when the top surface of the upper lid is pressed and recessed, the leading edge of the lower projection first reaches the liquid seal film, breaks through the liquid seal film, and gradually Since the liquid seal film is pierced at the edge, the liquid seal film can be smoothly ruptured even with a relatively light pressing force. Also, if the lower protrusion of the upper lid has a simple cylindrical shape, the lower end edge of the upper lid reaches the liquid seal film at the same time, so the liquid seal film is broken into a circle at once, and the fragments fall and become a container. Although there is a risk of causing noise with respect to the content liquid in the body, such a risk can be prevented by adopting a slanted cylindrical shape. In order to exhibit this effect reliably, as shown in FIG. 5, in the lowest position (virtual line position) when the upper projection 53 is pressed and the lower projection 52 is moved downward, the oblique cylindrical shape is It is preferable that the rear end portion (the left end portion in the figure) is designed so as not to reach the liquid sealing film 40 and to stop at the upper position. In this way, even when the top lid top surface 53 is pressed to the maximum extent, the liquid sealing film 40 is not cut over the entire circumference, and the non-cut portion is connected to the inner surface of the cap opening 35. Since it is held in a state where it is kept, no noise is given to the content liquid due to the fall of the fragments.
