Embodiment 1

[0016] The first embodiment of the locking structure of the lid of the airtight container of the present invention will be described below with reference to FIGS. 1 to 4 . Fig. 1 is an overall schematic diagram of a container with a locking structure for a lid of a sealed container according to the present invention. Fig. 2 is an enlarged perspective view of the cover structure. Fig. 3 is an end view of the cap body and the container neck after the screw connection is completed. Fig. 4 is a perspective view of the neck of the container main body with a part omitted. The internal thread is omitted in FIG. 2 . In Fig. 4, the internal thread and the clamping portion are omitted. Reference numeral 1 refers to a container, 2 refers to a cover body, 3 refers to a holding part, 4 refers to a cover part, 5 refers to a container main body, 6 refers to a notch provided on the peripheral wall of the cover part, and 7 refers to Support piece, 8 refers to the annular sleeve part, 9 ref...

Embodiment 2

[0019] Next, a second embodiment of the present invention will be described with reference to FIG. 5 . Fig. 5 is a perspective view showing the locking structure of the cover body according to the second embodiment of the present invention. In Fig. 5, external threads and internal threads are omitted. Reference numeral 15 denotes a fitting groove, and the components denoted by other reference numerals in this figure are the same as those in the first embodiment. The container body 5 in this embodiment is cylindrical. The clamping portion 3 and the cover portion 4 are integrally molded into one body, while the clamping portion 3 is adapted to the shape and outer diameter of the container main body 5 . An annular fitting groove 15 is formed at the periphery of the neck portion 9 at the top of the container main body while being aligned with the peripheral wall of the cover portion 4, a spiral bottom is formed in the fitting groove, and an acute angle cutout is formed at one en...

Embodiment 3

[0021] A third embodiment of the present invention will be described below with reference to FIG. 6 . Fig. 6 is a schematic diagram showing the locking structure of the cover body in the third embodiment. Reference numeral 16 refers to the end surface of the external thread on the opening side of the container, 17 refers to the groove surface at the end of the internal thread on the upper bottom side, and other reference numerals are the same as those in the first embodiment. Since FIG. 6 is a schematic diagram showing the structures and shapes of 16 and 17 , parts of the external and internal threads are omitted. The end 16 of the external thread on the open side is shaped such that the face of the end is perpendicular to the thread and the groove of the internal thread terminates in such a way that the face of the end groove on the upper bottom side of the internal thread arranged on the hood is aligned with The threads are vertical. In this structure, the end of the exter...

Abstract

A cover body locking structure for a sealed vessel, comprising a cover body composed of a grip portion of concave cross section and a cap portion disposed in the middle inner side of the grip portion, a notch formed in the peripheral wall end surface of the cap portion to extend in a direction orthogonal to the threads, a vessel main body neck base portion having a raise portion of the same diameter as the outer periphery of the cap portion, the raised portion being formed with a notch extending orthogonal to the threads, wherein on completion of threaded engagement between the cap portion and the vessel main body neck portion, the notch abuts against the notch formed in the peripheral wall end surface of the cap portion, and a region of the grip portion is always associated with the predetermined region of the vessel main body.

Description

technical field [0001] The present invention relates to a container lid body locking structure formed by a container body and a lid body screwed on the container body, and also relates to a lid body locking structure of a sealed container. In the locking structure In, the notch portion of the neck seat portion of the container body and the notch portion formed perpendicular to the screw thread on the periphery of the cap portion are brought into contact so that the cap integrally molded with the cap portion A certain area of ​​the body always corresponds to a predetermined area of ​​the main body of the container, and an annular skirt portion (annular skirt portion) disposed at the center of the bottom of the lid and subjected to inclined processing is used to enhance the sealing performance. Background technique [0002] Usually, the kind of container that the container neck is screwed into the cap has such a structure, that is, the structure that the external thread and th...
