Description

[Detailed description of the invention]

[0001]

The present invention relates to a resin container,
In particular, the present invention relates to a resin container having an opening tapered to a body diameter, an inner plug having a small-diameter nozzle fitted in the opening, and a surfactant-containing liquid contained therein.

[0002]

2. Description of the Related Art Liquids containing surfactants include, for example, liquid detergents (particularly kitchen detergents). Generally, the liquid detergent is contained in a resin container (hereinafter, simply referred to as a container), and an appropriate amount is discharged from the container during use.

[0003] A container of this type has a substantially cylindrical body 10 containing a liquid detergent, for example, as shown in Fig. 5, and is connected to the body 10 so that the upper part of the body 10 is squeezed inward. In addition, there is an approximately cylindrical shape having a mouth portion 11 tapered with respect to the diameter of the body portion 10 and an inner plug body 12 having a small-diameter nozzle 12a fitted into the mouth portion 11. FIG.
Around the opening 11, a spiral convex portion 11a for screwing a cap (not shown) is formed. In order to use the liquid detergent in the container shown in FIG. 5, first, the user grasps the body 10 by hand, and then compresses the body 10 with the mouth 11 turned downward, The liquid detergent is discharged from 11 to attach an appropriate amount of the liquid detergent to a cleaning sponge or the like.

[0004]

When the liquid detergent contained in the container is continuously used, the liquid detergent usually remains on the nozzle 12a of the inner plug 12 so as to cover the nozzle 12a. The film forms. In this case, when the user grasps the body 10 of the container by hand for use of the liquid detergent, the internal pressure of the body 10 increases, and the liquid detergent remaining in the nozzle 12a and forming a film becomes bubbles. The problem of scattering. The tendency of the residual liquid detergent to become bubbles is stronger as the thickness of the container is smaller, the capacity of the container is larger, and as the amount of the liquid detergent is reduced.

[0005] To solve this problem, it is conceivable to increase the thickness of the container to increase the rigidity of the container. However,
At present, there is a high demand for reducing the thickness of the container in order to reduce the cost. Contrary to this requirement, increasing the thickness of the container leads to an increase in cost, which is not preferable.

Further, as shown in FIG. 6, it is conceivable to employ a container 15 having a handle 14 provided on an upper portion of a body 13 so that the container can be held without grasping the body of the container. However, since this type of container has a complicated shape due to the presence of the handle 14, not only the mold becomes complicated and expensive, but also the thickness of the container may be increased because the rigidity of the container must be ensured. Unavoidable. Further, from the viewpoint of reducing the amount of resin used, the body should be cylindrical as much as possible. However, in this type of container, it is difficult to form the cross section of the body into a cylindrical shape because of securing rigidity and the like. In addition, there remains a problem that it is difficult to reduce the size due to the presence of the handle.

The present invention has been made in view of the above-mentioned conventional problems. An object of the present invention is to increase the rigidity of a resin container even if the thickness of the resin container is small.
An object of the present invention is to provide a resin container capable of preventing a surfactant-containing liquid from scattering from a nozzle when a surfactant-containing liquid such as a liquid detergent is used.

[0008]

The present invention has the following configuration to achieve the above object. That is, the present invention
A resin container having a mouth tapered with respect to the body diameter, fitted with an inner plug having a small-diameter nozzle in the mouth, and containing a surfactant-containing liquid therein. A resin container characterized in that at least a pair of recesses are formed near the center in the longitudinal direction of the body in the vicinity of the center of the side surface.

[0009]

In the present invention, at least a pair of recesses are formed near the center of the side of the body in the longitudinal direction of the body (corresponding to the axial direction of the cylindrical body). The rigidity can be greatly increased as compared with a thick container. Therefore, even if the user grips the container when using the liquid, the body becomes difficult to dent, and when the container is lifted, the finger is caught on the upper part of the concave portion, so that the container can be lifted without applying pressure inside the container, and the internal pressure is reduced. Because it does not go up
Spattering of the surfactant-containing liquid remaining in the mouth can be prevented.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention; 1 is a perspective view of a container (resin container) according to a first embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along line AA including a center line of the container in FIG. ) Is BB in FIG.
FIG. 4 is a cross-sectional view perpendicular to the container center line along the line. FIG.
In FIG. 2 and FIG. 5, the same parts as those in FIG.

As shown in FIGS. 1 and 2, in the container, a body 20 containing a liquid detergent is formed in a substantially cylindrical shape, and the body 20 is provided near the center of the side surface of the body 20. A pair of vertically long concave portions 21 are formed so as to face the longitudinal center line of the body portion 20.

[0012] Since the container is formed in a cylindrical shape, a larger amount of liquid detergent can be incorporated as a container formed with the same amount of resin than containers of other shapes. Further, since the pair of concave portions 21 is formed, the shape of the mold of the container may be simple, and the cost can be prevented from increasing.

Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 3A is a perspective configuration diagram,
(B) is sectional drawing orthogonal to the container center line which follows CC line of (a). As shown in FIG. 3, the container of the second embodiment differs from the first embodiment in that a pair of recesses 21 are formed, and a recess 23 is formed in the body 22 so as to face the center line of the body 22. Are formed in two pairs. The recesses 23 are formed so as to be separated from each other at an angle of about 90 ° about the center line of the body 22.

According to the container of the second embodiment, the recess 23
Are formed in two pairs, so that the rigidity is further increased as compared with the first embodiment. Also, as described above, approximately 9
Since the body 22 is spaced apart at an angle of 0 °, the strength of the body 22 is almost uniform, and therefore, the body 22 is prevented from being depressed with a uniform strength regardless of the direction in which the body 22 is gripped. can do.

Next, a container according to a third embodiment of the present invention will be described with reference to FIG. 4A is a perspective view of the container, and FIG. 4B is a cross-sectional view of the container taken along a line D-D and perpendicular to the center line of the container. As shown in FIG. 4, the container of the third embodiment has four concave portions 25 formed near the center of the side surface of the body portion 24 so as to draw an outwardly open arc.
Convex portions 26 are formed on the side surfaces of the torso between the five. Further, the protrusion 26 is formed so that the circumferential length S of the body 24 in the circumferential direction is shorter than the outer circumferential length L of the recess 25 (S <L).
According to this container, since the convex portion 26 forms a skeleton, the container has high strength, and thus the container is less deformed when the container is held. In addition, when the container is held, the finger is always inserted into the concave portion 25, so that the container is greatly caught and can be reliably held without dropping.

The present invention is, of course, not limited to the configurations of the first to third embodiments. That is, the shape and the number of the concave portions may take aspects other than the above embodiment. For example, a container in which three pairs of concave portions are formed in the body is also included in the container of the present invention. However, the present invention is not limited to this configuration, and the present invention includes a container in which more than three pairs of concave portions are formed, a container in which concave portions having different sizes are mixed, and a container in which the concave portion is divided into two or more. Of course.

Also, the surfactant-containing liquid contained in the container of the present invention is not limited to the above-mentioned liquid detergent. In addition, the shape of the mouth of the container is not limited to a substantially cylindrical shape as shown in FIGS. 1 to 4. In other words, as long as the mouth is tapered with respect to the body diameter, other shapes of the mouth may also be used. The present invention is of course included.

[0018]

As described above, in the vicinity of the center of the side of the body, the longitudinal direction of the body (corresponding to the axial direction of the cylindrical body).
Since at least a pair of recesses are formed so as to face the center line, the rigidity can be much higher than that of a container having the same thickness. Therefore, when the user uses the liquid, even if the user grips the container with the mouth part directed upward, the trunk is unlikely to be dented. In addition, the container can be lifted without applying pressure inside the container, as the fingers are hooked on the upper part of the recess when lifting the container. Therefore, since the internal pressure does not increase, excellent effects such as prevention of scattering of the surfactant-containing liquid remaining in the mouth can be obtained.
