Description

[Detailed description of the invention] <Industrial field of application> The present invention is suitable for seasonings that have good sealing properties and are convenient for repeated attachment and detachment, and especially for seasonings with a viscous filling such as mustard. This invention relates to a stopper combined with a relatively wide-mouthed container, which is suitable for taking seasonings from the opening of the container with a spoon or the like.

<Conventional technology and its problems> Conventionally, packaged seasoning products have generally been designed to maintain sealing properties during the distribution process and during use, while at the same time providing convenience for repeated attachment and use. With this in mind, stoppers that combine a crown and a replacement stopper, stoppers such as cork stoppers that tightly fit into the opening of a container, and stoppers that thread into the opening of a container are used. However, these stoppers have a problem in that they cannot be put on and taken off repeatedly, and are actually difficult to use. If you try to maintain a tight seal, the opening of the container and the stopper will become strong, as if they were stuck together, and conversely, if you try to facilitate repeated attachment and detachment, the adhesion will deteriorate. Put it away. Some containers are so concerned about convenience that even if the container is tipped over, the seasonings inside will spill out. Specifically, for example, some kind of tool is often required to open a crown or a cork stopper. Furthermore, for example, in the case of a stopper that is screwed into the opening of a container, it is difficult to say that it is a one-touch operation (meaning that the stopper only needs to be pushed into the opening of the container). especially,
When the seasoning is a viscous substance such as mustard paste that can be taken out from the opening of the container with a spoon, etc., a container with a relatively wide mouth is used. Crowns and cork stoppers are originally unsuitable for this purpose, and the stopper that is threaded into the opening becomes so strong that it is difficult to open it with just the force of the hand in order to maintain a tight seal.

Therefore, conventionally, as a plug that can be attached and detached with one touch,
It has been proposed that a ring-shaped protrusion is integrally formed at the lower part of a cylindrical body that fits into the opening of the container at a position corresponding to the shoulder of the container (Kokoku Publication No. 37-31161). However, this type of stopper has a ring-shaped protrusion that makes it difficult to remove the stopper, which limits the number of users who can use it, for example, for volatile agricultural chemicals. Because the body fits tightly against the inner circumferential surface of the container and the ring-shaped protrusion adheres tightly to the shoulder of the container, a seal is obtained, so a considerable amount of force is required to attach and remove the stopper. If housewives or children repeatedly put on and take off the stopper at home, it would be extremely difficult to use the stopper, and if an attempt was made to eliminate such stress, the problem would be that the sealing performance would be poor.

In addition, as another plug that can be attached and removed with one touch, a ring-shaped piece with an upwardly sloping outer end protruding from the outer circumferential surface of a tap-shaped plug has been proposed (Utility Model Publication No. 4480/1983). However, this stopper has
Although the ring-shaped piece has the advantage of providing a tight seal, since the ring-shaped piece that contacts the inner peripheral surface of the opening of the container is slanted upward, the stopper easily comes off, and in reality, the stopper is easily removed. There is a problem in that an additional outer cover is required to hold it down.

<Problems to be solved by the invention and means for solving them> The present invention solves the conventional problems as described above. To provide a stopper combined with a relatively wide-mouthed container, which is suitable for taking food from the opening of the container with a spoon or the like.

Therefore, in the present invention, a stopper that seals the opening of a container in which a relatively wide opening and a body wider than the opening are connected at a shoulder has an outer circumferential shape that is approximately the same as the inner circumferential shape of the opening. and has a foot portion having an outer circumferential diameter slightly smaller than the inner circumferential diameter of the opening, and two or more flexible tongue pieces are provided around the outer periphery of the foot portion in multiple stages at intervals, Each of these tongue pieces is curved in the opposite direction to the tip side of the foot, and when the foot of the stopper is pushed into the opening to seal the container, it is positioned directly below the opening. One tongue piece on the most distal side of the foot portion contacts the shoulder portion from below, and one or more other tongue pieces are formed so as to come into close contact with the inner circumferential surface of the opening portion. Pertains to a stopper combined with a container.

Hereinafter, the configuration of the present invention will be explained in more detail based on the drawings.

<Example> Fig. 1 is a front view showing an embodiment of the present invention, Fig. 2 is a partially enlarged vertical cross-sectional view of only the stopper, and Fig. 3 is a partially enlarged longitudinal cross-sectional view showing its usage condition. be. The container 11 has a wide opening 12 and a body 13 wider than the opening 12, which are connected by a shoulder 14. The stopper 21 is pushed into the opening 12 to seal the container 11.
The outer periphery shape is almost the same as the inner periphery shape of 2, and the opening 1
The leg portion 22 has an outer circumferential diameter slightly smaller than the inner circumferential diameter of the leg portion 22. Two flexible tongue pieces 23 and 24 are provided around the outer periphery of the foot part 22 in multiple stages at intervals, and these tongue pieces 23 and 24 are both located on the tip side of the foot part 22. It is curved in the opposite direction to 22a. When the foot 22 of the stopper 21 is pushed into the opening 12 to seal the container 11, the opening 12
The tip side 2 of the foot 22 will be located directly below the
The tongue piece 24 of 2a abuts the shoulder portion 14 from below, and the other tongue piece 23 is configured to fit tightly against the inner circumferential surface of the opening 12 as if being crushed.

The container 11 may be made of ceramic, glass, metal, plastic, wood, or a suitable laminate of these materials. The same applies to the stopper 21, but the tongues 23 and 24 are made of a flexible material such as plastic or rubber, and these are preferably made of soft polyethylene integrally molded with the stopper 21 as a whole. Also, in the drawing, there are two tongue pieces 23 and 24,
Although an example has been shown in which they are arranged in multiple stages at intervals, there is no particular restriction on the number of these as long as they are two or more.

<Operation> Next, the operation of the present invention will be explained. FIG. 3 is a partially enlarged vertical cross-sectional view showing the present invention in use. As shown in Fig. 3, when the stopper is pushed into the opening of the container, the upwardly curved tongue at the bottom of the figure, which is located directly below the opening, moves downward to the shoulder of the container. Since the stopper contacts from the side, the stopper will not come off the container even if the container falls over. Further, since the other tongue piece is pressed upwardly into close contact with the inner circumferential surface of the opening of the container, good sealing performance is maintained. In the case of the drawing, the two tongues work together to prevent the stopper from coming off the opening of the container and maintain the seal, and only the flexible tongue touches the shoulder. Since it is in contact with or in close contact with the inner peripheral surface of the opening, it can be opened even with a relatively small force. If three or more tongue pieces are provided in the same way, except for the one tongue piece on the most distal side that comes into contact with the shoulder, the other two or more tongue pieces will each touch the inner peripheral surface of the opening of the container. Since they are in close contact with each other, even better sealing performance is maintained. These tongues are made of flexible material such as soft polyethylene, so
A stopper that has excellent resilience, flexibility, and adhesion, and has tongues arranged in multiple stages at intervals can be simply pushed, pushed up, or pulled against the opening of the container. Repeated attachment and detachment is also extremely convenient.

<Effects of the Invention> As explained above, the present invention has the advantage that it has excellent sealing properties by itself and can be easily attached and detached by housewives and children with a single touch.
