Patent number: 4440309Abstract: A hermetical stopper used for liquid receptacles made of aluminum including minicasks of beer. Unlike the case in conventional receptacles in which the discharge ports usually have been hermetically sealed with aluminum as the same material for the main body, the hermetical stopper according to this invention is made independently of the main body so as to be able to put into and pull from out the discharge port at will, so that it is possible to be used repeatedly keeping the hermetically sealed state even after the primary use because of the discharge port being not necessary to be cut off purposely from the main body at the time of broaching the receptacle. In this way, this hermetical stopper according to the invention is very commendable also from the point of view of the effective use of resources.Type: GrantFiled: October 18, 1982Date of Patent: April 3, 1984Assignee: Totoku Co., Ltd.Inventor: Tsuyoshi Morimoto

Patent number: 4438552Abstract: A plastic fastener comprises an insertion leg of the general shape of the letter V, a pair of flange pieces disposed at the free ends of the insertion leg, and a pair of head pieces extended upwardly from the respective flange pieces. This fastener assumes its complete state by causing the head pieces to be twisted sidewise and moved past each other and subsequently allowing the rear edges of the head pieces to abut against each other. Two plates can be attached fast to each other simply by inserting the combined head portion of the fastener into the perforation formed in advance in one of the two plates and forcing the insertion leg into the perforation formed in advance in the other plate. Desired separation of the insertion leg from the latter plate is accomplished by moving the rear edges of the head pieces apart from each other.Type: GrantFiled: December 10, 1981Date of Patent: March 27, 1984Assignee: Nifco Inc.Inventor: Nobuaki Omata
