2. Description of the Related Art Conventionally, many sealing containers are known. For example, the sealing container disclosed in Japanese Utility Model Laid-Open No. 6-78262 has an outward flange at the lower part of the mouth and neck of the container, and a gap between the flange and the flange. An engagement ridge is provided around the outer surface of the upper neck portion of the flange with a small gap therebetween, and a ridge fitted between the outward flange and the engagement ridge is provided on the inner surface of the lower end portion. A cap having a peripheral wall provided is provided and fitted to the outer surface of the mouth and neck portion. From the lower end of the cap peripheral wall, a skirt-like thin cylinder that presses the lower surface of the outer peripheral portion to the upper surface of the outer peripheral portion of the outward flange is projected and provided. A break line is provided above and below the cap peripheral wall portion surrounding the mouth and neck portion above the engagement ridge, and the cap peripheral wall portion between these break lines is used as a removal fracture band, and a part of the fracture band is formed. At the same time as cutting, a knob is attached to one end of the cut portion, and the knob is pulled strongly. By removing the breaking band, the upper cap portion can be attached and detached, and if the breaking band is not removed, the lower end of the skirt-like thin cylinder and the cap peripheral wall are pushed up using a jig as appropriate. When the lid is opened, the thin skirt-shaped thin cylinder is deformed, and the deformed portion cannot be restored, so that there is evidence that the lid is illegally opened.

[0003]

The above-mentioned conventional sealing mechanism is convenient when the diameter of the mouth and neck of the container body and the peripheral wall of the cap are relatively large, and when the diameters of these are small, the size of the knob is large. It is somewhat inconvenient because of the relationship with The present invention proposes a sealed container which is easy to make even when the mouth and neck of the container body and the peripheral wall of the cap are small in diameter and in which the lid is easily opened.

[0004]

As a first measure, the liquid storage container body 1 standing up from the mouth and neck 4 and the outer periphery of an outwardly flanged top wall 13 attached to the lower end of the nozzle cylinder 12 are used to form the mouth and neck. It consists of a synthetic resin nozzle member 11 which fits on the outer surface and hangs down the peripheral wall 14, and a synthetic resin cap 21 screwed to the nozzle cylinder 12.
A rotation preventing means and a pull-out preventing means are attached to each of the inner surfaces of the cap so that the rotation and removal of the peripheral wall 14 with respect to the mouth and neck part 4 are disabled, and a plurality of breakers 23 are attached to the lower end of the cap peripheral wall. An outward flange 24 was provided via the through hole, and the lower surface of the outward flange 24 was welded to the upper surface of the flange-like top wall 13 of the nozzle-equipped member 11. As a second means, the first means is provided, and any one of the plurality of breakers 23 is made the shortest and the order in which the distance from the short breaker 23a in the screw unscrewing direction of the cap is increased. Then, the length of the breaker was sequentially increased.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The sealing container of the present invention comprises a container, a member with a nozzle, and a cap. The container body 1 includes a mouth-neck portion 4 that stands on the mouth-neck portion 4 from the upper end of the body portion 2 via a shoulder portion 3.
A first ridge 5 having a reverse stab shape having a lower surface as an engagement surface is provided at a lower portion of the lip, and the outer surface of the mouth and neck portion above the first ridge 5 is provided at substantially equal intervals. A plurality of first vertical ridges 6 are provided vertically. The material of the container body may be any material such as glass and synthetic resin. However, when the nozzle cylinder is lengthened as shown in the figure, it is desirable that the container body be made of synthetic resin and formed so that the body can be elastically compressed.

Reference numeral 11 denotes a member having a nozzle made of a synthetic resin, which is fitted to the outer surface of the mouth and neck portion 4 from the outer periphery of an outwardly flanged top wall 13 provided at the lower end of the nozzle tube 12 having a lower half portion having a male screw tube. The peripheral wall 14 is hung down. On the inner surface of the lower end of the peripheral wall, there is provided a second ridge 15 which is engaged with the lower surface of the first ridge 5 so as not to be able to be pulled out, and on the inner surface of the peripheral wall above the second ridge, the first vertical member is provided. A second vertical ridge 16 that meshes non-rotatably with the ridge 6 is provided vertically. From the lower surface of the outward flange-shaped top wall 13, an inner cylinder 17 fitted to the inner surface of the mouth and neck of the container body is provided vertically.

A cap 21 made of synthetic resin is screwed onto the outer surface of the nozzle cylinder 12. The cap has an outer flange 24 attached to a lower end of a peripheral wall 22 thereof through a plurality of breakers 23. The outward flange 24 is provided on the upper surface of the outward flange-shaped top wall 13 of the nozzle-equipped member 11 described above. To be welded. The welding may be performed by ultrasonic bonding or any other means. In the illustrated example, as shown in FIG. 3, a welding ridge 25 is provided on the lower surface of the outward flange 24, and the welding is performed by ultrasonic bonding. From the inner surface of the upper end portion of the cap 21, a stopper 26 is provided to be fitted watertightly to the inner surface of the nozzle hole at the upper end of the nozzle cylinder 12.

As shown in FIGS. 5 and 6, the plurality of breakers 23 described above make any one of the plurality of breakers the shortest and, in the cap screw disengagement rotation direction, shorten the shortest one. The length of the breaker may be sequentially increased in the order of increasing distance from the breaker 23a. In this way, the cap rotation stress is concentrated on the shortest breaker when the cap is unscrewed, so that the one-to-one breaker is sequentially broken in order from the shorter breaker to the longer one. It will be. FIG. 5 shows that the outward flange 24 is eccentric with respect to the cap peripheral wall, and the gap 31 therebetween is narrowed on the right side and widened on the left side, so that the gap is narrowed, a middle part, and a wide part. FIG. 6 shows an example in which a single breaker 23a is provided.
The breakers are provided so as to be inclined in the direction opposite to the cap screw removing / rotating direction in order of increasing distance from the cap screw removing / rotating direction.

[0009]

According to the present invention, the outer wall of the mouth and neck 4 of the container body and the peripheral wall of the member 11 with the nozzle fitted to the outer surface of the mouth and neck are provided. A cap peripheral wall provided with rotation prevention means and pull-out prevention means on the inner surface and screwed to the nozzle cylinder 12 of the nozzle-equipped member.
At the lower end of 22, an outward flange 24 through a plurality of breakers 23
The outward flange 24 is attached to the nozzle-equipped member.
Since it was welded to the upper surface of the outward flange-shaped top wall 13 of 11, the liquid cannot be poured out by unscrewing the cap unless the breaker 23 is broken, and the cap 21 is screwed to the nozzle-equipped member 11. It is also impossible to remove these together from the mouth and neck of the container body with the removal prevention means described above, and since the rotation prevention means is provided, when removing the cap 21 from the nozzle cylinder 12, the nozzle There is no fear that the member 11 rotates with respect to the container body mouth and neck, so that the cap cannot be unscrewed,
The sealing effect can be enhanced. Furthermore, since there is no knob as in the conventional example described above, the knob does not become an obstacle, and the breaker can be easily cut by making it thin, so that even if the cap peripheral wall has a small diameter, the breaker can be used. There is no inconvenience in opening the lid due to breakage.

According to a second aspect of the present invention, the effect of the first aspect of the present invention is provided, and at least one of the plurality of breakers 23 is moved to the shortest direction from the short breaker, and the cap screw is disengaged in the turning direction. In order to increase the length of the breakers in order of distance, the breakers will break one by one in order from short and small breakers when the cap is unscrewed, so that it is easier than when the breakers are broken simultaneously. It can be broken.
