Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to an opening/closing device for bottles or containers such as various containers such as bottles, cans, cartons, and boxes.

2. Description of the Related Art Conventionally, devices of this type as shown in FIGS. 2 to 4 have been widely used. Although the figure shows an opening/closing device for a bottle as an example, this is not limited to a bottle, and may be any other container such as a carton or a box.

In Figure 2, a is the mouth of the bottle or container;
A synthetic resin inner stopper b is attached to this opening a. c and d are attachment parts, e is a mouth wall, f is an endless fissure, g is a tear-off member such as a pull ring, and h is a taper-shaped pot. Further, i is an outer lid having a top wall j, and a cylindrical metatarsal foot k on the inner surface of the top wall j. This middle leg k is in close contact with the syringe h and is adapted to be sealed. Further, l is a mounting part for the mouth part a, and is screwed together, for example.

This type of opening/closing device is prized because it can be sealed until the first use due to b.

Problems to be solved by the invention However, the above bottle or container opening/closing device has the following problems. That is, sauce, soy sauce, etc. are stored in a bottle or container a, and when this is to be used, the outer lid i is first removed, the fissure groove f is torn off by the tearing member g, an opening is formed, and the bottle is opened. When the bottle, etc. is tilted, the liquid content is poured out from the pouring tube (h), and then the dispensing is stopped, the bottle, etc. is tilted, and when placed on a counter (not shown), etc., droplets of liquid such as sauce, soy sauce, etc. are poured out. Note tube h
The liquid returns to the spout a from the upper surface of the barrel, but in this case, the liquid does not return completely, and a droplet m may adhere to and remain on the injection barrel h. When the outer barrel i is attached in this state, the droplets m gradually descend from the top of the barrel h and accumulate between the barrel h and the middle leg k. Then, when this outer lid i is removed and placed with the inner surface facing upward as shown in FIG. 3, the droplet m moves from the midfoot k to the top wall j. Next, when this outer lid i is attached to the mouth part a as shown in FIG. It brings about sanitary conditions.
In addition, in FIGS. 2 to 4, the case where the outer lid i is attached to the mouth part a is shown, but this is just an example, and the invention is not limited to this. For example, the outer lid i may be attached to the inner stopper b. It's okay to be.

This invention was made in order to solve such problems, and its purpose is to provide an opening/closing device for a bottle or container, which has an inner stopper b having the above-mentioned pouring barrel h, and an outer lid i having the above-mentioned middle foot k. In this case, even if the above-mentioned opening/closing and dispensing operations are carried out, the contents of the liquid will not reach the attachment part l of the outer lid in the above-described manner, and an unsanitary condition can be prevented. This is to obtain the open and closed status of the container.

Means for Solving the Problems This invention which achieves the above object is described as follows: an inner stopper 4 having a barrel-like barrel 1 and a mounting part 3 to be attached to the mouth end 2 of a bottle or container; A mouth part 5 formed by the inner stopper 4 and the mouth end part 2; a top wall 6 and an outer cylinder 7 integrally provided on the top wall 6, and is attached to the attachment part 8 of the mouth part 5. An outer lid 10 having a mounting portion 9; a cylindrical metatarsal foot 11 provided on the inner surface of the top wall 6 and in liquid-tight contact with the inside of the pour barrel 1; an endless protrusion provided on the lower surface of the top wall 6; 12; A bottle or container opening/closing device characterized in that the tip 12b of the inner surface 12a comprises the protrusion 12 positioned above the inwardly inclined inner inclined surface 1a of the pourer 1. .

Function: The user tilts the bottle or container and pours out its contents from the spout 2 through the syringe 1. Then, when the tilt of the bottle or container is corrected and dispensing is stopped, the droplet 1
4 returns over the pouring tube 1 and flows down into the spout 2, but some of it remains on the pouring tube 1. In this case, the outer lid 10
When the liquid droplet 14 is attached to the spout 5, the droplet 14 accumulates between the middle foot 11 of the outer lid 10 and the barrel 1. Next, if the outer cover 10 is removed from this state, the droplet 14 will be released from the midfoot 1.
Move to 1. When this outer lid 10 is turned upside down as in the conventional example, the droplets 14 tend to spread on the inner surface of the top wall 6, but in this case, an endless protrusion 12 is formed on the inner surface of the top wall 6. Therefore, the droplet 14
is fixed inside this protrusion 12. Then, when this outer lid 10 is attached to the spout 5 as shown in FIG. By being positioned above the outer cover 10, the droplets 14 do not reach the mounting part 9 of the outer lid 10, and do not stain the mounting part 9 and make it unsanitary.

Embodiment In FIG. 1, reference numeral 1 denotes a pouring barrel, which is made of synthetic resin and is attached to the mouth end 2 of a bottle or container by a mounting portion 3 formed integrally therewith. 4
indicates the inner stopper formed in this way. Further, 5 indicates a mouth portion formed by the inner stopper 4 and the mouth end portion 2.

6 is a top wall of the outer cover 10, and an outer cylinder 7 is integrally provided with this. Reference numeral 8 indicates an attached part, and 9 indicates an attached part. 11 is the middle foot, 12 is the protrusion, 12a is the inner surface of the protrusion 12, and 12b is the same inner surface 12a.
The tip is shown. Reference numeral 14 indicates a droplet, 15 indicates a mouth wall of the inner stopper 4, 16 indicates an endless groove formed in the mouth wall 15, and 17 indicates a tearing member.

Although the attachment part 9 is attached to the attachment part 8 of the inner stopper 4 in the figure, it may also be attached to an attachment part formed in the mouth end part 2, although not shown. .

The operation of this embodiment is almost the same as that of this invention described above, so a description thereof will be omitted.

Effects of the invention As a result of this invention being constructed as described above, the droplet dripping from the protruding part 12 is accommodated in the inner surface of the pouring barrel 1, and as a result, it reaches the attachment part 9 of the outer lid 10 and closes this part. It is possible to prevent soiling and unsanitary conditions.
