Container sealing device
First Claim
1. A container sealing device provided with an inner plug and an upper closure and enabling attachment and detachment of the upper closure by a first screwing part provided between the upper closure and a container or the inner plug, wherein:
- the inner plug has a body part releasably coupled to a separation part such that an opening is formed when the separation part detaches from the body part;
the upper closure has a support part for the separation part provided in the inner plug;
the separation part is coupled to the support part by a second screwing part provided between the support part and the separation part;
the second screwing part is in a reverse thread relation with respect to the first screwing part; and
a first stopper is provided between the separation part and the upper closure, wherein the separation part is screwed onto the second screwing part to a depth that the first stopper forms a contact between an upper end of the separation part and the upper closure and/or a lower end of the support part and the separation part, thereby preventing significant further advancement of the separation part onto the second screwing part,wherein a second stopper is provided forming a contact between the upper closure and the body part of the inner plug, and wherein the second stopper is provided at a lower end of a second inner cylinder part provided at the upper closure.

Abstract
An object is to provide a container sealing device which can perform an opening of an inner plug with a clear opening feeling. An inner plug 10 is assembled in advance to an upper closure 20 by using a second screwing part 52. At this time, since an assembling interval between a separation part 12 and the upper closure 20 can be adjusted by tip end parts 16t and 20u of a cylindrical part 16 which are first stoppers and the small-diameter cylinder part 20d, the second screwing part 52 can be brought into a lock state of being screwed to the deepest position or a state close to that. In opening the plug, the first screwing part 51 is loosened the second screwing part 52 is tightened, and the separation part 12 can be rapidly and reliably separated from a body part 10b of the inner plug 10.
