Description

[0001]
[Industrial applications]
The present invention relates to a portable container, and more particularly, to a portable container that can store contents such as tablets, granules, and powders and can take out the contents in a dispenser.
[0002]
[Prior art]
There are various types of portable containers. For example, Japanese Utility Model Publication No. 5-39091 and Japanese Utility Model Application Laid-Open No. 5-54351 disclose a technique that makes it easy to take out a certain amount of contents from a portable container by operating a specific lever attached to the portable container. Is shown.
[0003]
However, in a portable container provided with the lever, it may be convenient to take out the contents therefrom.However, if the contents come out extra, the lever becomes an obstacle and the contents are removed. Sometimes it can't be undone.
[0004]
Further, all or a part of the portable container may be made of a transparent material so that the contents of the portable container can be seen from the outside of the portable container. However, in this case, the contents of the portable container may be discolored or deteriorated when the contents of the portable container are exposed to ultraviolet rays.
[0005]
When a portable container is made of a transparent synthetic resin, a UV-blocking agent such as a benzophenone-based or benzotriazole-based synthetic resin is used to protect the contents contained in the portable container from ultraviolet rays. It is usually added to However, such a substance may be eluted from the synthetic resin, adhere to the contents, and change the quality or / and the color of the contents.
[0006]
[Problems to be solved by the invention]
The portable container of the present invention is invented in view of the above point, and it is easy to take out the contents of the portable container from the portable container, and furthermore, take out the contents from the portable container extra. Even if it has, the extra amount can be easily returned to the portable container, and even if the portable container is made of a transparent material, it is technically necessary to prevent the contents from being adversely affected by ultraviolet rays. Make it an issue.
[0007]
[Means for Solving the Problems]
In order to solve the above problems, a portable container of the present invention has the following configuration.
That is, in a portable container made of a soft synthetic resin having an outlet through which the contents can be taken out in a dispenser, the outlet forms a lip portion composed of a pair of lip pieces at one edge of an outer peripheral edge of the portable container. When the soft synthetic resin applies an external force inward in the width direction of the outlet, each of the mouth corners located at the boundary between the pair of lips and at both ends in the width direction of the outlet is mutually connected. The outlet is opened by approaching another corner of the mouth, and on the other hand, when the external force is released, each of the corners of the mouth has an elasticity enough to separate from the other corner of the mouth and naturally close the outlet. Then, of the pair of lips, one lip has a plurality of protrusions formed along the longitudinal direction and at intervals, and the other lip fits with the plurality of protrusions. It has a concave portion.
[0008]
Here, examples of the soft synthetic resin include low-density polyethylene, elastomers, and rubbers mixed with low-density polyethylene.
In addition, it is preferable that an aluminum oxide-coated titanium oxide / sintered sinter is blended with the soft synthetic resin as an ultraviolet cut agent.
[0009]
In the portable container of the present invention, the material used for the portable container is made of a soft synthetic resin, and the outlet of the portable container forms a lip portion composed of a pair of lip pieces on one edge of the outer peripheral edge of the portable container. When the soft synthetic resin is applied with an external force inward in the width direction of the outlet, each corner of the mouth located at the boundary between the pair of lips and located at both ends in the width direction of the outlet is formed. The mouth opening is opened while approaching each other to the other corner, while the elasticity is such that when the external force is released, each of the corners is separated from the other corner and naturally closes the opening. The pair of lips constituting the lip are separated from the other lips only by applying an external force inward in the width direction of the outlet, thereby opening the outlet. Further, the pair of lips constituting the lip portion approach each other only by releasing the external force applied when opening the opening, and as a result, the opening is closed. Therefore, opening and closing of the outlet of the portable container can be performed extremely quickly.
[0010]
In addition, since there is a gap between the plurality of protrusions provided on one lip piece, when opening the outlet, it is possible to provide a plurality of protrusions on one lip piece on one lip piece. It does not hinder.
[0011]
Further, if the portable container is tilted toward the user's palm with the outlet opened, the contents will flow out of the outlet. At this time, even if the contents come out more than necessary, keep the take-out port away from the user's palm, and if the portable container and palm are tilted so that the palm is up, The contents that have flowed into the portable container from the outlet. Therefore, as long as the size of the outlet is set to an appropriate size so as to be convenient for such an operation, the required amount of contents can be ultimately easily removed from the portable container extremely easily.
[0012]
In addition, since the soft synthetic resin is mixed with aluminum oxide-coated titanium oxide / bengala sintered material which is a substance having a high ultraviolet absorbing effect, it is possible to prevent the contents from being adversely affected by ultraviolet rays. In addition, since it is not a chemically synthesized ultraviolet cut agent, it does not elute from the soft synthetic resin, and there is no fear of adhering to contents.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
<Overall configuration (see Fig. 1)>
The portable container 1 has a flat and substantially rectangular parallelepiped shape as a whole, and has flanges projecting from four edges. The portable container 1 is obtained by integrally assembling a pair of transparent plastic bodies 3 and 5 having substantially the same shape in appearance by ultrasonic welding. Then, contents such as tablets, granules, and powders are put into the portable container 1, and the contents can be freely taken out as needed. For this reason, one edge of the portable container 1 is not welded, and serves as an outlet 7 that opens and closes as needed.
[0014]
Each of the transparent plastic bodies 3 and 5 is a soft synthetic resin that can be sufficiently bent by human power, and the soft synthetic resin includes an aluminum oxide-coated titanium oxide / bengala sintered product which is an ultraviolet ray-cutting agent having a high ultraviolet absorbing effect. Is blended.
<Transparent plastic bodies 3, 5 (see FIGS. 1, 2, 4, 6, 7, and 9)>
As described above, the pair of transparent plastic bodies 3 and 5 have substantially the same shape, but are slightly different in a portion constituting the outlet 7 and a portion necessary for welding. Details will be described.
[0015]
Each of the pair of transparent plastic bodies 3 and 5 has a very similar external shape, and has a rectangular pan shape having a flange extending in all directions. Of the four edges of these transparent plastic bodies 3, 5, except for the flanges 9, 9 'formed on one edge in the longitudinal direction constituting the outlet 7, the other flanges 13, 15, and 17 and 13', 15 'And 17' have the same width dimension and are narrower than the flange associated with the outlet 7.
[0016]
A concave portion 11 is formed on an opposing surface 9 a of the transparent plastic body 3, which is a joining surface with the flange 9 ′ of the transparent plastic body 5, among the flanges 9 of the transparent plastic body 3. Of the other flanges 13, 15, and 17, the opposite surfaces 13a, 15a, and 17a, which are the bonding surfaces of the transparent plastic body 5 with the flanges 13 ', 15', and 17 ', are welded as welding allowances which melt during welding. 21 are formed. The formation range of the welding strip 21 extends over the entire range from one end 13b of the flange 13 to one end 17b of the flange 17 via the flange 15. Further, both ends of the welding strip 21 have portions 21a orthogonal to the direction in which the welding strip 21 extends. Therefore, both ends of the welding strip 21 each have a shape like a T-shape. By doing so, the welding area when the welding strip 21 is welded is increased, and the welding strength is accordingly increased. The reason for this is to sufficiently withstand the stress repeatedly generated by opening and closing the outlet 7.
[0017]
Note that, as described above, the formation direction of the welding strip 21 is described from the one end 13b of the flange 13 to the one end 17b of the flange 17, so that the one end 13b of the flange 13 is set as the starting end of the welding strip 21 and the one end 17b of the flange 17 is set as the starting end. Although the description has been made such that the end of the welding strip 21 can be taken, the one end 17b of the flange 17 may be the starting end of the welding strip 21 and the one end 13b of the flange 13 may be the end. For convenience, it is merely stated as such.
[0018]
A plurality of convex portions corresponding to the concave portions 11 and fitted to the concave portions 11 are provided on a flange 9 ′ corresponding to the outlet 7 of the other transparent plastic body 5 and corresponding to the flange 9 of the transparent plastic body 3. 23, 23,... Are formed. Are also formed in the longitudinal direction of the flange 9 'over a range of about two-thirds of the entire flange 9'.
[0019]
Nothing is formed on the other flanges 13 ', 15' and 17 'of the transparent plastic body 5 corresponding to the flanges 13, 15 and 17 of the transparent plastic body 3, respectively.
<Recess 11 of transparent plastic body 3 (see FIGS. 1, 2, 3, 5, and 8)>
The concave portion 11 of the transparent plastic body 3 has an elongated groove shape having a length of about two thirds of the entire flange 9 and is located at the center of the flange 9 in the width direction. Further, a projection 27 having a semicircular cross section extending in the longitudinal direction is formed at the tip of the upper long edge 25 of the recess 11. Therefore, a portion of the upper long edge 25 that does not have the protrusion 27 is a concave streak 28 that is relatively recessed as compared with the protrusion 27. Further, a lower long edge 29 of the concave portion 11 is a slope 29. Note that the terms “up and down” as used herein mean upper and lower in the up and down direction when facing FIG. 4.
<Protrusion 23 of transparent plastic body 5 (see FIGS. 1, 3, 5, 6, and 8)>
The convex portions 23, 23,... Of the transparent plastic body 5 are fitted with the concave portions 11 of the transparent plastic body 3, and each convex portion 23 has a certain gap 30 between the other convex portions 23. Is opened and formed. The entire shape of the convex portion 23 has a shape as if a semicircular column 31 parallel to the upper side of one side of the truncated quadrangular pyramid is joined. The semi-cylindrical column 31 fits into the concave streak 28 of the concave portion 11 when the convex portion 23 is fitted into the concave portion 11. The surface 33 of the convex portion 23 facing the surface on which the semi-cylindrical column 31 is formed faces the inclined surface 29 of the concave portion 11. In this embodiment, four projections 23 are formed. In addition, there are three gaps 30, and the shape of the gap is a truncated quadrangular pyramid shape when the projection 23 is inverted with respect to the projection 23, but is smaller than the projection 23.
<Assembling of the transparent plastic body 3 and the transparent plastic body 5 (see FIGS. 1, 6, and 10)>
In order to integrate such a transparent plastic body 3 and the portable container 1 having the transparent plastic body 5 as a constituent member, the transparent plastic body 3 and the transparent plastic body 5 are overlaid. At this time, the welding strip 21 is sandwiched between the flanges 13, 15 and 17 and the flanges 13 ', 15' and 17 '. When the welding strip 21 is melted by the ultrasonic welding device, the opposed flanges are integrated.
[0020]
On the other hand, the flange 9 of the transparent plastic body 3 and the flange 9 'of the transparent plastic body 5 are not welded. Therefore, the flange 9 and the flange 9 ′ can be opened, and the flange 9 and the flange 9 ′ provided in the flange 9 and the flange 9 ′ are fitted to each other to fit the flange 9 and the flange 9 ′. 'Can be closed. Therefore, the portion corresponding to the flange 9 and the flange 9 ′ when the transparent plastic body 3 and the transparent plastic body 5 are joined together becomes the openable / closable outlet 7 of the portable container 1. In addition, by making the outlet 7 in this way, the flange 9 and the flange 9 'form a lip portion as if it were a pair of lip pieces. A portable container 1 for storing and removing contents such as a body is completed.
[0021]
In addition, a portion between the flange 9 and the flange 9 ′, which is located at both ends in the width direction of the outlet 7, is denoted by reference numeral 32, and this portion is called a mouth corner because it resembles a human mouth corner. And When an external force is applied to each of the mouth corners 32, 32 so as to approach each other, the outlet 7 is opened as shown in FIG. 10, while when the external force is released, the mouth corners 32, 32 are released. Are separated from the other corners of the mouth so that the outlet 7 naturally closes as shown in FIG.
[0022]
The soft synthetic resin, which is the material of the portable container 1, has such an elasticity that the opening 7 can be easily opened and closed by human power.
<Effects of Embodiment>
In the portable container 1 according to the present embodiment, the outlet 7 of the portable container 1 has a flange 9 in the form of a human lip composed of a pair of lips on one edge of the outer peripheral edge of the portable container 1 and a flange 9. 9 ′, and the material of the portable container 1 is a soft synthetic resin, so that when an external force is applied to the portable container 1 inward in the width direction of the outlet 7 by a person, the flange 9 and the flange 9 ′ Each of the mouth corners 32, 32 located at the boundary portion and located at both ends in the width direction of the outlet 7 opens the outlet 7 to approach each other to each other (see FIG. 10). On the other hand, when the external force is released, the elasticity of the soft synthetic resin acts, so that each of the corners 32, 32 separates from each other and closes the outlet 32 naturally (FIG. 1). reference). Therefore, opening and closing of the outlet 7 of the portable container 1 can be performed very quickly.
[0023]
Since there is a gap 30 between the plurality of protrusions 23 provided on the flange 9 of the transparent plastic body 5, when opening the outlet 7, the plurality of protrusions 23, 23 are bent to bend the flange 9. Providing 23 on the flange 9 does not hinder.
[0024]
Further, if the portable container 1 is tilted toward the palm of the user with the outlet 7 opened, the contents flow out from the outlet 7. At this time, even if the contents come out more than necessary, the outlet 7 is kept away from the user's palm, and if the portable container 1 and the palm are tilted so that the palm is up, the palm can be held. The discharged contents flow into the portable container 1 from the outlet 7. Therefore, as long as the size of the outlet 7 is set to an appropriate size so as to be convenient for such an operation, the required amount of contents can be finally removed from the portable container 1 extremely easily. .
[0025]
In addition, since the soft synthetic resin is mixed with aluminum oxide-coated titanium oxide / bengala sintered material which is a substance having a high ultraviolet absorbing effect, it is possible to prevent the contents from being adversely affected by ultraviolet rays.
[0026]
In this embodiment, both the transparent plastic bodies 3 and 5 are transparent. However, only one may be transparent and the other may be opaque.
[0027]
【The invention's effect】
As described above, according to the portable container of the present invention, the material used for this is made of a soft synthetic resin, and the outlet of the portable container has a pair of outer peripheral edges of the portable container. A lip portion composed of a lip piece, the soft synthetic resin is a boundary portion between the pair of lip pieces when an external force is applied inward in the width direction of the outlet, and both ends in the width direction of the outlet. Each of the corners of the mouth comes closer to the other corner of the mouth and opens the outlet, while when the external force is released, each of the corners of the mouth moves away from the other corner of the mouth to remove the corner. Because it has elasticity enough to close the outlet naturally, just applying an external force inward in the width direction of the outlet, the pair of lips constituting the lips separate from each other, Open the outlet. Further, the pair of lips constituting the lip portion approach each other only by releasing the external force applied when opening the opening, and as a result, the opening is closed. Therefore, opening and closing of the outlet of the portable container can be performed extremely quickly.
[0028]
In addition, since there is a gap between the plurality of protrusions provided on one lip piece, when opening the outlet, it is possible to provide a plurality of protrusions on one lip piece on one lip piece. It does not hinder.
[0029]
Further, if the portable container is tilted toward the user's palm with the outlet opened, the contents will flow out of the outlet. At this time, even if the contents come out more than necessary, keep the take-out port away from the user's palm, and if the portable container and the palm are tilted so that the palm is up, it was in the palm The contents flow from the outlet into the portable container. Therefore, as long as the size of the outlet is set to an appropriate size so as to be convenient for such an operation, the required amount of contents can be ultimately easily removed from the portable container extremely easily.
[0030]
In addition, since the soft synthetic resin is mixed with aluminum oxide-coated titanium oxide / bengala sintered material which is a substance having a high ultraviolet absorbing effect, it is possible to prevent the contents from being adversely affected by ultraviolet rays. In addition, since it is not a chemically synthesized ultraviolet cut agent, it does not elute from the soft synthetic resin, and there is no fear of adhering to contents.
