Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a packaging container improved so as to be stronger than conventional products both at an internal pressure and an external pressure, and a container containing a reagent such as a liquid reagent such as formalin or a powdered reagent.

[0002]

[Prior art]

 In a container of this type, which is conventionally known, the cross-sectional shape of the packing is rectangular, the fitting groove of the packing is also rectangular, and the packing is fitted so that no gap is formed.・ It did not have a tapered female surface. For this reason, it was not possible to say that it was sufficiently resistant to high internal pressure changes and high external pressure changes, which were caused by temperature changes caused by higher and lower ambient temperatures. However, there is a long-awaited need for a container that can respond more sufficiently to the above-mentioned changes in the internal and external pressure from the standpoint of safety measures.

[0003]

[Problems to be solved by the invention]

 An object of the present invention is to provide a novel container and a container containing a reagent obtained by conducting research and development to meet the above-mentioned long-awaited needs.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, a container according to claim 1 of the present invention has a bottomed cylindrical container body provided with a male screw on an outer peripheral surface of an opening edge, and the male screw and a screw provided on an inner peripheral surface of a peripheral wall. With respect to a container comprising a dish-shaped lid provided with a female screw which can be freely fitted, a tapered female surface is provided on the inner peripheral edge of the opening end surface of the container body, the diameter of which is gradually reduced toward the inside, and a top wall of the lid is provided. In this case, a low annular protruding wall protruding along the peripheral wall is formed at a location slightly inside the peripheral wall to form a rectangular groove, and the outer peripheral surface of the annular protruding wall is tightly fitted to the outer peripheral edge of the tapered female surface. A tapered male surface whose diameter is gradually increased as it goes toward is provided, and separately from these, an annular packing with a cross section having an upper side shorter than the width of the rectangular groove and a lower side having a trapezoidal shape is formed, and this annular packing is formed into a rectangular groove. When the cover is pushed in and closed, the lower side of the Are those formed by to assume a state and tapered male surface and the tapered female surface exhibits a pressure collapsed state by the opening end face in close contact of the body,

[0005] Similarly, a reagent-containing container according to claim 2 has a bottomed cylindrical container body provided with a male screw on an outer peripheral surface of an opening edge portion, and is capable of screwing with the male screw on an inner peripheral surface of a peripheral wall. With respect to a reagent-containing container comprising a dish-shaped lid provided with a female screw, a tapered female surface whose diameter is gradually reduced toward the inside is provided on the inner peripheral edge of the opening end surface of the container body, and the top wall of the lid is A rectangular annular groove is formed by projecting a low annular protruding wall along the peripheral wall at a position slightly inside the peripheral wall, and outwardly closely fitting the outer peripheral edge of the top surface of the annular protruding wall to the tapered female surface. Provide a tapered male surface that gradually increases in diameter as it faces, and separately form a ring-shaped packing with a trapezoidal shape whose upper side is shorter than the width of the rectangular groove and whose lower side is longer. When the lid with reagent is closed, the annular The tapered male surface and the tapered female surface are in a state where the lower side surface of the container is crushed and crushed by the opening end surface of the container body.

[0006]

【Example】

 In the embodiment shown in the figure, a cylindrical main body 2 with a bottom is provided with a male screw 1 on the outer peripheral surface of the opening edge portion using a colorless transparent hard plastic, and the male screw is provided on the inner peripheral surface of the peripheral wall with a milky white hard plastic. A dish-shaped lid 4 provided with a female screw 3 which can be screwed with 1 is formed, and a tapered female surface 5 whose diameter is gradually reduced toward the inside is provided on the inner peripheral edge of the opening end surface of the container body 2. Also, a shallow rectangular groove 8 is formed by integrally projecting a low annular projecting wall 7 along the peripheral wall 6 at a position slightly inside the peripheral wall 6 on the top wall of the lid 4, and a top surface of the annular projecting wall 7. The outer peripheral edge is provided with a tapered male surface 9 whose diameter gradually increases as it goes outward to be tightly fitted to the tapered female surface 5, and is further provided separately with chemical and heat resistant synthetic rubber or elastomer. A cross section having a trapezoidal shape whose upper side is shorter than the width of the rectangular groove 8 and whose lower side is longer. An annular packing 10 is formed, and the annular packing 10 is pushed into the rectangular groove 8 so that it cannot be pulled out. When the lid is closed, the lower side surface of the annular packing is crushed by the opening end face 11 of the container body 2. And the tapered female surface 5 and the tapered male surface 9 are in close contact with each other.

In the present invention, the annular packing 10 is stored in the rectangular groove 8 with a space 12 formed in the side surface as shown in the figure, and is crushed by the opening end face 11 of the container body 2 when the lid is closed. And escapes to the gap 12.

[0008]

[Effect of the invention]

 The container and the container containing the reagent according to the present invention are provided with a tapered female surface whose diameter is gradually reduced toward the inside on the inner peripheral edge of the opening end surface of the container body, and a portion of the top wall of the lid slightly inside the peripheral wall. And a rectangular groove is formed by projecting a low annular projecting wall along the same peripheral wall, and the diameter is gradually increased outward as it fits tightly to the tapered female surface on the outer peripheral edge of the top surface of the annular projecting wall. A tapered male surface is provided, and separately from these, an annular packing having a cross section having a trapezoidal shape in which the upper side is shorter than the width of the rectangular groove and the lower side is long is formed, and this annular packing is pushed into the rectangular groove, and is placed. When the lid is closed, the lower side surface of the annular packing is crushed by the opening end face of the container body, and the tapered male surface and the taper female surface are in close contact with each other. Annular packing at the end Into the gap 12 to secure a deeper so-called bite of the opening end face itself, and also to secure a strong adhesion between the tapered male face and the tapered female face, that is, a screw for the lid. By the tightening operation, a deep bite into the annular packing at the opening end surface and the close contact between the tapered male surface and the tapered female surface are all folded at once, ensuring even higher airtightness than the conventional product. Therefore, the intended purpose of responding to the above demands by providing packaging containers that are significantly more resistant to internal and external atmospheric pressure fluctuations than conventional products, and containers containing reagents such as liquid reagents such as formalin and powdered reagents. It has a significant effect to achieve completely.
