Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without any inventive step, are within the scope of the present invention.
Referring to the attached drawings of the specification, a bottle mouth sealing structure of an in vitro diagnosis reagent bottle comprises a reagent bottle, wherein a bottle mouth 10 is arranged on the reagent bottle, a bottle cap 20 is connected on the bottle mouth 10 in a matching manner, an external thread 11 is arranged on the bottle mouth 10, an internal thread 21 is arranged in the bottle cap 20, a sealing ring 30 matched with the inner wall of the bottle mouth 10 is further arranged in the bottle cap 20, when the bottle mouth 10 and the bottle cap 20 are locked and matched, the top end part of the bottle mouth 10 is tightly matched with the inner top end part of the bottle cap 20 in a fitting manner, the bottle mouth 10 and the bottle cap 20 are made of non-same materials, in the embodiment of the invention, the external thread 11 is matched with the internal thread 21 to form a first sealing part 41, the sealing ring 30 is matched with the inner wall of the bottle mouth 10 to form a second sealing part 42, the sealing ring 30 adopts an inverted buckle type interference manner, more specifically, the sealing ring, the specific parameter is 0.07-0.10mm, the top end part of the bottle mouth 10 can be closely matched with the inner top end part of the bottle cap 20 to form a third sealing part, and the sealing structure at the three parts further enhances the sealing performance of the bottle mouth of the reagent bottle and prevents liquid leakage. In addition, in the preferred embodiment of the present invention, the bottle mouth 10 is made of polypropylene, the bottle cap 20 is made of high density polyethylene, and in the traditional reagent bottle material design, the reagent bottle and the bottle cap 20 are both made of polypropylene, and since the hardness of the reagent bottle and the bottle cap made of the same material is consistent, during the transportation and storage of the product, the locking internal stress is released, and the locking rebound phenomenon exists, so as to cause liquid leakage.
Furthermore, in the embodiment of the present invention, the bottle mouth 10 is made of polypropylene, and the bottle cap 20 is made of high density polyethylene, and the principle is that the rockwell hardness of polypropylene is about 95, the rockwell hardness of high density polyethylene is about 65, and the two hardness differences result in mutual tightening and difficult loosening during locking, and long-term experimental demonstration shows that after the bottle cap and the bottle mouth made of the same material are locked by a 10kg.f electric batch, 6 to 7kg.f is needed when the bottle cap and the bottle mouth are opened on the same day, the bottle cap and the bottle mouth are placed for about a week and are unscrewed again by the electric batch, and the bottle cap and the bottle mouth can be unscrewed only by 2 to 3kg.f, so that the bottle cap and the bottle mouth have the risk of loosening. After the bottle bodies and the bottle caps made of different materials are locked by a 10KG.F electric screwdriver, the opening force is almost unchanged along with the change of time, the situation that about 600PCS products are placed for a week and subjected to a negative pressure 60KPA test is verified, and no liquid leakage phenomenon is found.
Further, sealing washer 30 is the annular form, sealing washer 30 sets up and forms integratively with bottle lid 20 on the interior terminal surface of bottle lid 20, and is more specific, sealing washer 30's outer wall is provided with first inclined plane 31 and second inclined plane 32, first inclined plane 31 leans out, second inclined plane 32 leanin, be provided with the radius angle between first inclined plane 31 and the second inclined plane 32, its aim at, the in-process that bottle lid 20 and bottle neck 10 were screwed, earlier by the contact of the top of second inclined plane 32 and bottle neck 10, it has the effect of a smooth direction, makes things convenient for sealing washer 30 to enter into the inner wall realization of bottle neck 10 and seals.
Further, the inclination of the first inclined surface 31 is 8 degrees, and the structure that the first inclined surface is inclined outwards can further enhance the contact area between the sealing ring 30 and the bottle mouth 10, so that the sealing effect is further ensured.
Further, the reagent bottle comprises a bottle body and a cover plate, the bottle body and the cover plate are fixed through ultrasonic welding, and the bottle mouth 10 is arranged on the cover plate.
In the use process, the user can realize the sealing effect of the three sealing positions by screwing the bottle cap 20 on the bottle mouth 10.
While the foregoing description shows and describes the preferred embodiments of the present invention, it is to be understood that the invention is not limited to the forms disclosed herein, but is not to be construed as excluding other embodiments and is capable of use in various other combinations, modifications, and environments and is capable of changes within the scope of the inventive concept as described herein, commensurate with the above teachings, or the skill or knowledge of the relevant art. And that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
