Description

[0001]
The present invention relates to a petri dish tucker that organizes and stores petri dishes used for inspection, testing, research, and the like of various pathogens.
[0002]
[Prior art]
In general, for example, many petri dishes are used for testing O-157, influenza and other pathogens. Therefore, there is a need for a petri dish tucker that can stack petri dishes and store them compactly.
[0003]
Conventionally, as a petri dish tucker, four semi-cylindrical petri dish housing parts having a curvature corresponding to the size of the petri dish are formed back-to-back on the polycarbonate stacker body and the edge of the open end of each housing part Attaching an elastic presser plate from the upper end to the lower end of the container, stacking and receiving the petri dish in the housing part, elastically pressing the outer wall of the petri dish with the presser plate, and preventing the petri dish from falling off the housing part What is configured to do this is known.
[0004]
The conventional shearless tacker has the following features. (1) Since a plurality of (about 10 to 20) petri dishes are stacked and can be stored in an orderly manner, the petri dishes can be stored compactly in a narrow space. (2) The petri dish can be prevented from falling off even if the petri dish tucker is carried. (3) The petri dishes accommodated can be taken out independently of the stacked positions.
[0005]
By the way, in order to prevent adherence of germs and the like, the Charlestacker is frequently sterilized by an autoclave or the like during use, and therefore it is necessary to make it from a material that can withstand high temperatures (about 120 ° C). Polycarbonate is used as the material of the main body, and the holding plate is made of silicon rubber. Therefore, there is a problem that the material cost becomes high, and the equipment such as a production die becomes large due to the molding, and as a result, the production cost becomes high.
[0006]
Therefore, the inventor of the present invention has the purpose of providing inexpensively the shearless tacker having the features as described in the above (1) to (3) at a low cost. ) Was proposed prior to the present invention (see Japanese Patent Application No. 10-76511). In this prior art, as shown in the figure, a base base 101 composed of rings 101A, 101B, and 101C made of metal cages and four pieces vertically erected on the base base 101 at approximately equal intervals in a circular direction. And the four petri dish holding members 106A, 106B, 106C, 106D disposed on the base table 101 with the restriction rod interposed therebetween, and the holding member 106A ... 106D is composed of a metal cage, and is formed in an arc shape that is nearly half-circular or nearly circular by removing a half of the circular shape corresponding to the size of the petri dish, with a predetermined distance in the vertical direction. A pair of semi-circular horizontal ring rods 107 and 108, vertical coupling rods 109 and 110, which connect the opposite ends of the upper ring rod 107 and the lower ring rod 108, respectively; The holding members are arranged in a back-to-back manner with the removal side facing outward, and the outer portions of the upper and lower ring rods 107 and 108 are fixedly attached to the restriction rods, respectively. The petri dish housing part 111 is configured such that the vertical connecting rods 109 and 110 and the arrangement regulating rod to which the ring rods 107 and 108 are fixed regulates the movement of the petri dish in the lateral direction and stacks and accommodates the petri dishes. It will be. The restriction rods 102... 105 are connected to each other, that is, the upper ends of the restriction rods 102 and 104 and 103 and 105 are connected by horizontal connection rods 112 and 113. 114 is attached.
[0007]
According to the above prior art, when a force in the separating direction is applied to both vertical connecting rods 109, 110 of the petri dish holding members 106A ... 106D, both connecting rods 109, 110 are elastically caused by the spring action of the upper and lower ring rods 107, 108. When the force is released, both connecting rods return to the original state by the spring action. Therefore, when the petri dish is held by hand and lightly pressed between the two connecting rods, the petri dish passes between the two connecting rods and enters the accommodating portion 111, and at the time when the diameter portion of the petri dish passes through the both connecting rods. Both cages return elastically, and the petri dish is regulated in lateral movement by the arrangement regulating rods and the two coupling rods, and is housed in an orderly manner in a state of being stacked in the housing portion 111. And by picking and pulling the arbitrary petri dish accommodated in the accommodating part with a finger, both said connecting rods open elastically, Therefore A desired petri dish can be taken out. In addition, since the structure is simplified, mass production can be performed at low cost and high heat resistance is provided, so that sterilization can be performed by an autoclave or the like.
[0008]
However, it has been found that there is still room for improvement in the following points in the prior art Charles Tucker. That is, according to the prior art, the lateral movement of the petri dish S is regulated in the housing portion 111 by the two connecting rods 109 and 110 of the petri dish holding member and the predetermined two regulating rods among the arrangement regulating rods 102. They are stacked and accommodated. The petri dish holding members 106A... 106D are housed in the housing portion 111 of the holding member 106A as shown in FIG. The petri dish S can be easily pulled out from the side between the two restriction rods 109 and 110. However, when the petri dish S is taken out from the upper end side of the housing portion, if the petri dish S is picked with a finger and slid upward, the upper surface of the petri dish S Since the peripheral edge hits the lower surface of the upper ring rod 107, it is difficult to take out the petri dish S while maintaining the horizontal state.
[0009]
Therefore, when the petri dish S is taken out from the upper end side of the housing portion, an operation of lifting the petri dish S while performing an operation such as tilting the petri dish S is required. Therefore, it takes time to take out the petri dish from the upper end side of the holding member, and when the petri dish is inadvertently applied and tries to take out the petri dish from the upper end side, the petri dish strikes the ring rod and the petri dish There is also a risk of falling.
[0010]
[Problems to be solved by the invention]
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a shearless tacker that uses the advantages of the prior art as they are and solves the problems of the prior art.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a metal base table and a plurality of metal support rods that are vertically arranged at substantially equal intervals in the circular direction and located on the center side of the base table. And a plurality of petri dish holding members, which are made of metal rods and arranged on the base table, and each holding member lacks a half of a circular shape corresponding to the size of the petri dish and has a semicircular shape. The upper and lower semicircular horizontal ring rods are formed in an arc shape close to a round shape, and are provided at a predetermined distance in the vertical direction, and the upper ring ring and the lower ring Each of the holding members are arranged in a back-to-back manner with the removal side facing outward, and an upper end side and a lower end side. The inner side of the ring rod is fixedly attached to the support rod, respectively. Wherein both rings rod with both vertical connecting rod is characterized by being configured the dish accommodating portion for accommodating a stack of Petri dish to regulate the lateral movement of the petri dish and the support rod which is fixed.
[0012]
According to the present invention, the following effects are exhibited. When a force in the separating direction is applied to both vertical connecting rods of the petri dish holding member, the two connecting rods are elastically opened by the spring action of the upper and lower semicircular horizontal ring rods, and when the force is released, both connecting rods are Returns to the original state by the action. Therefore, by holding the petri dish by hand and pressing it lightly between the two connecting rods, the petri dish passes between the two connecting rods and enters the accommodating portion, and when the diameter portion of the petri dish passes through both the connecting rods, The petri dish is elastically restored, and the petri dish is restrained in lateral movement by the support rod and the connecting rods, and is housed in an orderly manner in a state of being stacked in the housing portion. And by picking and pulling the arbitrary petri dish accommodated in the accommodating part with a finger, both said connecting rods open elastically, Therefore A desired petri dish can be taken out. Further, by applying a strong force in the contact / separation direction to both connecting rods, or by applying a strong force in the opening or closing direction to both ends of both ring rods, the diameter of the upper and lower ring rods of the holding member can be reduced. The distance between the connecting rods can be finely adjusted by changing the size. The necessity of the distance interval adjustment will be described later in the section of the embodiment of the invention. Furthermore, since the holding members are attached by fixing the inner parts of the upper and lower ring rods to the support rod, the upper surface of the petri dish will strike the ring rod even if the petri dish accommodated in the accommodating portion slides upward. Never do. Therefore, the petri dish can be easily taken out from the upper end of the housing portion.
[0013]
In the present invention, the number of the support rods and the number of petri dish holding members are not particularly limited and can be arbitrarily set. For example, a range of about 3 to 6 (pieces, pieces) can be mentioned. . Further, in the present invention, as in the invention described in claim 3, each holding member can adopt a configuration in which the two ring collars of the adjacent holding members are fixed to each other.
[0014]
Among the present inventions, the invention according to claim 4 is the invention according to claim 1, 2 or 3, wherein each holding member is a semicircular reinforcing horizontal shape formed in substantially the same shape and size as the ring. The reinforcing horizontal ring rod is positioned between the ring ring on the upper side and the ring rod on the lower side, the inner part is fixed to the support rod, and both ends are It is characterized by being fixed to a vertical connection rod.

[0022]
As shown in FIG. 6, the petri dish S is composed of a petri dish body S ₁ having a circular flat bottom and a lid S ₂ fitted to the upper end of the opening of the main body S ₁ . The petri dish S has a tentative standard such as a diameter of 30 mm, 45 mm, 75 mm, 95 mm, etc., which is determined based on a 15 mm interval. However, even a petri dish with the same standard has some dimensional errors depending on the manufacturer. In other words, for example, there are several manufacturers of standard petri dishes with a diameter of 90 mm, but each manufacturer makes its own about 90 ± 3 mm. The dimensional error of ± 3 mm (maximum 6 mm) is absorbed and adjusted by fine adjustment of the distance between the connecting rods 33 and 34.
[0023]
In this embodiment, the rings 11A and 11B are provided on the inner side of the ring base 12 of the base base 1, and the petri dish placing the lowermost petri dish S accommodated in the accommodating part 36 by the both rings 11A and 11B. Although the portion 11 is configured, the mounting portion may be configured by, for example, horizontally projecting a plurality of short rods on the inner side of the ring rod 32 on the lower side of each holding member. In short, what is necessary is just to comprise so that the lowest petri dish S accommodated in the accommodating part 36 may be received holding a horizontal state.
[0024]
The petri dish tucker of this embodiment is configured as described above. When force is applied to the vertical connecting rods 33 and 34 of the petri dish holding members 3A. When the ring rods 31 and 32 are elastically opened by the spring action of the ring rods 31 and 32 and the force is released, both the connecting rods 33 and 34 are elastically returned to their original positions. Therefore, by holding the petri dish S by hand and inserting it between the connecting rods 33 and 34 and pressing it lightly, the petri dish S elastically opens and passes through the connecting rods 33 and 34 and enters the housing portion 36. When the position of the diameter portion of the petri dish passes through both the rods 33 and 34, the both rods elastically return, so the petri dish S is formed by the vertical rod 21 of the support rod and the connecting rods 33 and 34 of the holding member. The lateral movement is restricted and the sheets are stored in an orderly manner in a state of being stacked in the storage portion 36 (see FIGS. 7 and 8).
[0025]
Next, among the petri dishes S housed in the housing part 36 as described above, the connecting rods 33 and 34 are elastically opened by picking and pulling an arbitrary petri dish S with a finger. Only the container 36 can be taken out. Further, the petri dish S in the housing portion 36 can be freely taken out from the upper end side of the housing portion 36 by lifting it up by hand.
[0026]
Furthermore, by applying a strong force in the contact / separation direction with respect to both connecting rods 33, 34, or by applying a strong force in the opening direction or the closing direction with respect to both ends of both ring rods 33, 34, the spring action is achieved. The distance between the connecting rods 33 and 34 can be adjusted by changing the diameters of the upper and lower ring rods 31 and 32 and the intermediate ring rod 35 of the holding members 3A. Yes (see FIG. 9). Therefore, in consideration of the above-mentioned dimensional error of the same standard of the petri dish maker, by operating as described above, the distance between the connecting rods 33 and 34 is finely adjusted so as to match the size of the petri dish. It is possible to adapt by absorbing the dimensional error by the manufacturer. In addition, the petri dish is repeatedly put in and out, so that the interval between the two connecting rods 33 and 34 may be wider than the initial setting, and the petri dish cannot be sufficiently held. The holding force can be easily restored by adjusting the distance between both the rods 33 and 34 by operating to.
[0027]
【The invention's effect】
The present invention has the following effects. (1) A plurality of petri dishes can be stacked and stored in an orderly and compact manner. (2) The petri dish can be prevented from inadvertently dropping off while carrying the petri dish tucker. (3) Only the desired petri dish can be easily taken out regardless of the position where the petri dish accommodated in the accommodating part is stacked. (4) The petri dish can be easily taken out of the accommodating part from the upper end side of the accommodating part by lifting the petri dish in the accommodating part by hand. (5) Since the configuration is simplified, it can be mass-produced at low cost. (6) Since it is made of a metal material and has high heat resistance, it can be sterilized by an autoclave or the like.
