Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a creamy substance pouring container in which a medium plate is installed inside the container body to prevent the negative pressure in the container body from being negatively slid in response to sucking the creamy substance by suction.

[0002]

[Prior art]

 This kind of dispensing container is very well known, and various kinds have been conventionally provided. FIG. 2 shows an example of a manual pump type dispenser body among them, and the dispenser body 10 is attached to the mouth / neck portion 11 of the container body 1 with a screw cap 12.

To explain its operation, as shown in the figure, the movable portion of the cylindrical piston 13, the stem 14, and the push-down head 16 with the nozzle tube 15 is normally moved to the return spring 17 via the cylindrical piston 13. It is pushed up to the upper limit position, that is, the position where the upward step of the lower part of the stem 14 is locked to the opening peripheral edge of the top plate of the screw cap 12.

At this time, the rod member 19 of the inner shaft of the cylinder 18 is pulled up slightly from the lower limit position by the ridge 20 on the inner surface of the intermediate portion of the stem 14 via the expanded portion at the upper end, and thus the rod member 19 The outer peripheral surface of the lower end of the cylinder 18 is slightly separated from the inner peripheral surface of the lower portion of the cylinder 18, that is, the suction portion is open.

Further, when the rod member 19 is pulled up, the lower end of the return spring 17 is positioned slightly above the circumferentially discrete spring seat 21 on the inner surface of the cylinder 18, as shown in FIG. The rod member 19 is on the upper surface of the collar 22 below the bar member 19.

Here, when the pressing head 16 is pushed down against the return spring 17 to pour out the creamy substance, the stem 14 and the piston 13 descend together, but at the beginning of the descending, they must return as described above. Since the lower end is located at a position slightly above the spring seat 21 and on the collar 22, the push down pushes the rod member 19, which causes the lower peripheral surface of the rod member 19 to come into pressure contact with the inner peripheral surface of the lower portion of the cylinder 18. Then, the suction part is closed, and the creamy product in the cylinder 18 is pressurized by the above-mentioned pressing down, and this pressed creamy product is between the outer surface of the bar member 19 and the inner surface of the upper end of the piston 13. Through the gap and the gap between the upper outer surface of the rod member 19 and the inner surface of the stem 14, the discharge valve 23 is opened and the liquid is poured out from the nozzle pipe 15.

When the pushing down is stopped at the end of pouring, each part returns to the original state by the return of the return spring 17, and the inside of the cylinder 18 becomes negative pressure due to this return, so that the suction state is in the open state at this time. The creamy substance in the container body 1 is sucked up into the cylinder 18 from the portion to prepare for the next pouring.

On the other hand, the suction at the time of this return causes the inside of the container body 1 to have a negative pressure, but a middle plate (not shown in FIG. 2) slides up inside the container body 1 in relation to the atmospheric pressure, Prevent negative pressure of 1. Reference numeral 24 in the figure is a guide tube for stabilizing the vertical movement of the movable part.

[0009]

[Problems to be solved by the device]

 The inner tray for preventing negative pressure of the container body 1 described above is formed in an inverted tray shape so that it can slide in a well-balanced and stable manner, and is usually made of a hard synthetic resin material.

In the case of the medium plate made of this hard material, it has the advantage of not impairing the content liquid because it is excellent in non-permeability, but on the other hand it is difficult to have a little sealing property because of its low slip resistance. Therefore, a high level of technology is required for the interior of the container body 1 to be processed with high precision.

Further, since the sliding resistance is small, if the container is accidentally dropped or given an impact, the inner plate may drop down and fall off.

The present invention is to obtain a creamy substance pouring container provided with a container body in which a negative pressure preventing inner plate that can improve the sealing property without impairing the impermeability is installed.

[0013]

[Means for Solving the Problems]

 The present invention relates to a creamy substance pouring container in which an inner tray 2 made of a hard material of an inverted tray shape for preventing negative pressure is slidably installed in a container body 1. The lower part 4 has a stepped shape with the lower part 4 having a larger diameter than the upper part 3 and a thin peripheral wall vertically provided. The upper part projects to the outer surface of the thin peripheral wall 4 of the middle plate 2 and the upper part up to a space 6 around the thick peripheral wall 3. A cylindrical body 9 made of a soft material, which is extended and provided with protrusions 7 and 8 on the outer surfaces of the upper and lower portions located in the empty space 6 is fitted and fixed.

[0014]

[Action]

 When the inner plate 2 has the above-mentioned structure, the inner plate 2 has the cylindrical body 9 on the outer surface of the thin peripheral wall 4 slidingly contacting the inner wall surface of the body of the container 1 via the upper and lower protrusions 7 and 8.

Since the tubular body 9 is formed of a soft material, a high sealing property can be obtained by appropriately pressing the tubular body 9 against the inner wall surface of the body of the container body 1, and the conventional body 9 can have a high sealability. No processing or assembly technology required.

Further, although this cylindrical body 9 has a large slip resistance, the sliding contact area of the container body 1 on the inner wall surface of the container body is the two ridges 7 and 8 of the upper and lower two lines, and the sliding contact area is small, and the inner peripheral wall No. 4 is thin and bendable, and the upper ridge 7 can also be bent toward the space 6, so the sliding resistance can be set to an appropriate value by adjusting the degree of pressure contact of the lower ridge 8 to the inner wall surface of the body of the container 1. Therefore, there is no problem such as stagnation of the ascending slide, and there is no concern that the inner plate 2 will fall down even if there is a drop impact.

Further, since the hard peripheral wall 4 is provided inside the tubular body 9, the impermeability is not impaired, and there is no risk of deteriorating the contents such as creamy products.

【Example】

 An embodiment will be described below with reference to FIGS. 1a and 1b.

In this embodiment, the pump-type dispenser body 10 is the same as the dispenser body 10 shown in FIG. 2 described in the prior art, and therefore the dispenser body 10 has already been described. Further, since the gist of the present invention is not directly related to the dispenser body 10, the same reference numerals as those in FIG. 2 are given and the description thereof is omitted. Reference numeral 25 denotes a cover that covers the dispenser body 10.

The container body 1 is also well known, but for the sake of convenience, this container body 1 has an engagement groove 26 in which the cover 25 is fitted near the upper end of a straight tubular body. In addition, the lower end of the body is opened, a ventilation hole 27 is opened in the center of the open bottom, and a bottom member 30 in which double mounting peripheral walls 28 and 29 are erected on the peripheral edge is attached to the lower part of the body. It is attached by fixing it.

The inner plate 2 is integrally formed by insert molding or the like with a cylindrical body 9 made of a soft synthetic resin material such as an elastomer on the outer surface of the hanging peripheral wall of the body of the inverted tray shape made of a hard synthetic resin material such as polypropylene. It is formed by external fitting.

The main body of the middle plate 2 has a peripheral wall hanging from the peripheral edge of the top plate 5. In this case, the lower peripheral wall 4 hanging downward from the upper peripheral wall 3 is expanded to have a stepped shape, and the peripheral wall 4 is It is thin enough to be bendable and has an outward protruding edge 31 at the lower end. The central portion of the top plate 5 is largely recessed in a mortar shape so as to correspond to the lower shape of the upper cylinder 18, and a support tube 33 is hung from the lower surface of the recessed portion 32.

The cylindrical body 9 made of a soft material is provided with ridges 7 and 8 on the outer surfaces of the upper and lower parts, the lower end is placed on the outward protruding edge 31, and the upper part is extended to a vacant part 6 around the thick wall 3 and extended. The outer peripheral surface of the thin peripheral wall 4 is fitted to the outer surface of the thin peripheral wall 4, and the inward flange 34 is projected from the inner surface of the upper portion.

According to the structure of this embodiment, the inner plate 2 is brought into sliding contact with the inner wall surface of the body of the container body 1 via the ridges 7 and 8 on the upper and lower portions of the tubular body 9 made of a soft material. Therefore, by appropriately setting the sliding contact between the ridges 7 and 8, the ridges 7 and 8 can be assembled without requiring high processing and assembling techniques, and high sealing property can be obtained.

Further, the cylindrical body 9 has a large slip resistance, but it is the protrusions 7 and 8 of the upper and lower two lines that are in sliding contact with the inner wall surface of the body of the container body 1, and the sliding contact area is small, and the inner peripheral wall Since 4 is thin and bendable, and the upper ridge 7 can also be bent toward the cavity 6, it is possible to obtain an appropriate slip resistance by adjusting the degree of pressure contact of the lower ridge 8 to the inner wall surface of the body. Therefore, the problem that the ascending slide is stagnant does not occur, and even if there is a drop impact or the like, the situation where the inner plate 2 falls off can be eliminated.

Since the main body 2 of the inner tray 2 to which the tubular body 9 is attached is a hard material, the impermeability is not impaired and there is no risk of degrading the stored items. Further, since the main body and the tubular body 9 are made of two materials, there is an advantage that they can be color-coded.

In the above embodiment, the soft synthetic resin material is shown as the cylindrical body 9, but it may be rubber.

[0028]
