Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a container for efficiently removing a liquid such as food contained in a container, and a nozzle for the outlet thereof. In particular, it is more effective when applied to a wide variety of viscous liquids ranging from viscous sauces such as mayonnaise and ketchup to industrial products such as adhesives and paints.

[0002]

[Prior art]

 Conventionally, a viscous liquid contained in a tubular container is used by being squeezed from an outlet by applying pressure to the container. Such viscous liquids are very wide-ranging, from the above-mentioned sauce foods to chemical products such as toothpastes and adhesives. For products stored in these tube-shaped containers, two major issues are how to keep the area around the outlet from becoming dirty and how to remove the contents from the container. Along with the development of these products, the development of containers has also continued endlessly.

As a means for solving these two problems at once, the present applicant has proposed “attachment for viscous liquid container outlet” in Japanese Patent Application No. 2001-295624. This is an attachment that is attached to the outlet of the viscous liquid container.The cross-sectional area of the outlet of the attachment is made extremely small, and accompanying this, the cross-sectional area of the path leading to the outlet is gradually reduced. The tapered shape is such that it becomes narrower immediately before the outlet, and then becomes wider after being narrowed. As a result, the viscous liquid at the outlet is more easily cut, and there is almost no residue near the outlet, so there is no contamination.

If a viscous liquid container on which the attachment is mounted is turned upside down by providing a space in the attachment, a slight amount of the viscous liquid moves into the attachment by gravity, and the viscous liquid container moves from the viscous liquid container to the attachment. When all the viscous liquid has moved into the viscous liquid container, remove the attachment from the empty viscous liquid container and replace it with a new viscous liquid container to completely drain the viscous liquid from the old viscous liquid container. Can be done.

[0005]

[Problems to be solved by the invention]

 However, when using the nozzle described above, although dirt near the outlet of the attachment can be prevented, the liquid from the vicinity of the outlet when the container is turned upside down with the lid attached to the attachment so that it can be completely drained out. It is necessary to completely prevent leakage.

[0006] In view of the above, an object of the present invention is to provide a structure of an outlet of a liquid container that can prevent liquid leakage from near the outlet in order to solve this problem.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a liquid container in which a liquid is contained, the outlet of the outlet of the liquid container or the outlet of a nozzle attached to the outlet gradually reduces the cross-sectional area toward the outlet. The narrowest portion is formed just before the end of the end, and a slightly wide portion is formed from the narrowest portion toward the outlet.

[0008] Thus, when the container is returned after the liquid is taken out, the liquid slightly remaining at the outlet is drawn into the container, and the tip of the outlet is hardly soiled, so that the hermeticity is maintained.

According to the second aspect of the present invention, a detachable cap is provided at the outlet, and when the cap is mounted, the inside of the cap top and the tip of the outlet are in close contact with each other, and a space is formed between the periphery of the outlet and the inside of the cap. It was to so.

[0010] With this, even if a small amount of liquid adheres to the vicinity of the outlet, the liquid does not spread any more because the area around the outlet does not come into contact with the inside of the cap, and the hermetic seal can be maintained in a clean state.

[0011]

[Embodiment of the invention]

 An embodiment of the present invention will be described with reference to the accompanying drawings. Here, FIG. 1 is a side view of an example of a liquid container outlet nozzle according to the present invention, FIG. 2 is a longitudinal sectional view of the nozzle, FIG. 3 is a plan view of the nozzle, and FIG. FIG. 5 is a longitudinal sectional view showing a state in which the nozzle is attached to the outlet of the liquid container, FIG. 6 is a longitudinal sectional view of the lid, FIG. 7 is a bottom view of the lid, and FIG. FIG. 5 is a longitudinal sectional view showing a state where the liquid container is attached to an outlet of the liquid container with the liquid container attached.

[0012] The liquid container and the nozzle for the outlet of the liquid container according to the present invention can be used for various foods such as viscous sauces such as mayonnaise and ketchup, industrial chemical products such as adhesives and paints, and daily necessities such as toothpaste. When the contents are taken out of a container containing a wide range of liquids, the contents are completely used up without leaking the contents and without polluting the outlet. Therefore, for example, the nozzle 1 shown in FIGS. 1 to 4 is mounted on the container body 3 as shown in FIG.

That is, the nozzle 1 is screwed and mounted on the container main body 3, and has a screw portion 13 which is screwed to the container main body 3, and a cylindrical hollow inside. An intermediate portion 12 and a tapered tip portion 11 are formed, and an outlet 10 is formed at an end of the tip portion 11.

The tip portion 11 is formed so as to gradually decrease in diameter toward the outlet 10, has a narrowest portion in front of the outlet 10, and has a reverse tapered shape in which the tip portion is slightly widened. ing.

The intermediate portion 12 is a portion that communicates with the outlet 30 of the container body 3, and the inner diameter of the intermediate portion 12 is substantially the same as the diameter of the opening (not shown) of the outlet 30 of the container body 3. The opening is designed to allow the liquid to smoothly flow into the intermediate portion 12.

The outer peripheral surface of the intermediate portion 12 is formed with six radially spaced-apart nozzle ridges 14 like petals. The nozzle ridges 14 are effective as a positioning means described later, and having such a shape can prevent distortion due to shrinkage during resin molding. Further, a locking projection 15 for locking the lid 2 is provided below the nozzle protrusion 14.

In this embodiment, the nozzle 1 side is a female screw and the container body 3 side is a male screw. No screw groove is formed near the lower end of the screw portion 13. Further, as can be seen from FIG. 5, the screw groove can be screwed with a margin to the screw thread of the container screwing portion 33 of the container body 3, and the inner seating surface t of the nozzle 1 is The outlet 30 is securely brought into close contact with the outlet 30. At this time, if the screw groove is formed to the vicinity of the lower end of the screw portion 13, the thread between the internal seating surface t of the nozzle 1 and the upper surface of the outlet 30 of the container body 3 is not perfect, and the screw thread is formed. There is a risk of bottoming out.

Next, a method of using the nozzle 1 mounted on the container body 3 will be described. When removing the internal liquid (not shown), turn it upside down and apply pressure to the container body 3 to extract it. When pressure is applied to the container body 3, the liquid is squeezed out of the outlet 10 while filling the inside of the nozzle 1.

A liquid having a high viscosity will not come out when the pressure applied to the container body 3 is released, but a liquid having a low viscosity may slightly hang down beyond the outlet 10 in some cases. However, by returning the container body 3 to the original longitudinal direction, the liquid returns to the container body 3 by the weight of the liquid, and the liquid that has drooped slightly at the outlet by the pressure is drawn back into the nozzle 1. In particular, by making the vicinity of the outlet 10 reversely tapered, this retraction becomes more reliable, and it is possible to prevent the outlet 10 from being attached to the outer periphery and contaminated.

Here, the cap 2 serving as the lid will be described. The cap 2 has an inverted cup shape as shown in FIGS. 6 and 7, and is attached to and fixed to the nozzle 1 as shown in FIG. At this time, a nozzle unit is constituted by the nozzle 1 and the cap 2.

A projection 20 is formed inside the center of the top surface 21 of the cap 2, and an embankment-like annular projection 23 is provided around the projection 20. The projection 20 has a substantially hemispherical cross-section so that when the cap 2 is attached to the nozzle 1, it comes into close contact with the tip of the outlet 10. The annular projection 23 plays the role of a dike that ensures that the tip of the outlet 10 is in close contact with the projection 20 and that even if a small amount of liquid adheres to the projection 20, it does not spread any further.

The cap 2 is made of a resin having a slight flexibility. When the projection 20 comes into close contact with the tip of the outlet 10, the top surface 21 is slightly bent, and the pressure is used to press the projection to the tip of the outlet 10. As a result, it is possible to maintain reliable adhesion. Further, since a flange 22 slightly higher than the inside of the top surface 21 is formed on the outer peripheral portion of the top surface 21, even if the top surface 21 is slightly bent, the flange 22 maintains its height. Even if the liquid container is placed upside down with the cap 2 attached, it will not fall down.

On the inner peripheral wall of the cap 2, twelve cap ridges 24 are spaced at equal intervals, and the interval is such that the nozzle ridge 14 of the nozzle 1 can just enter. I have.

An annular locking concave portion 25 is formed near the lower end of the inner peripheral surface of the cap 2, and can be fixed to a fixed position when the cap 2 is mounted by being locked to the locking projection 15 of the nozzle 1. . The fixed position is a position where the top surface 21 of the cap 2 is slightly bent and the protrusion 20 is pressed against the tip of the outlet 10.

Here, the procedure for mounting the cap 2 will be described. When the liquid is taken out from the outlet 10 of the nozzle 1, it is confirmed that the liquid remaining near the outlet 10 has been drawn in as described above, and the cap 2 is put on. At this time, even if it is covered casually, the nozzle ridge 14 and the cap ridge 24 are fitted and can be covered in the mounting direction. Therefore, the protrusion 20 is securely brought into close contact with the tip of the outlet 10. By lightly pressing in this state, the locking projections 15 are locked into the locking recesses 25, and the projections 20 are hermetically sealed in a pressed state.

Since a space is provided around the outlet 10 so as not to contact the inside of the cap 2, even if a small amount of liquid adheres around the outlet 10, the cap 2 can be attached to the space. There is no spreading of the liquid and no further contamination.

In this state, the storage of the liquid is arbitrary depending on the type of the liquid, but in the case of a viscous liquid, it is desirably stored upside down in order to make it easy to take out in the next use. Even in such a case, the liquid does not leak out since the pressure contact of the protrusion 20 to the tip of the outlet 10 is maintained.

In the case where the liquid is stored upside down as described above, when the liquid inside becomes small, the liquid moves into the nozzle 1 due to its own weight. At this point, when pressure is applied to the liquid container 2, air pressure is applied to the entire liquid surface, and most of the slightly remaining liquid can be discharged from the nozzle 1. If the last remaining liquid does not move into the nozzle 1 due to high viscosity, etc., it is necessary to shake the container body 3 with the lid 2 attached, since the cap 2 is securely sealed. Can be moved into the nozzle 1.

Some liquids cannot completely discharge the liquid remaining in the nozzle 1 at the end. However, when the liquid has completely moved into the nozzle 1, the nozzle 1 is removed and a new liquid is removed. By attaching to the container body 3, the remaining liquid can be pushed out by a new liquid.

Although the embodiment of the present invention has been described above assuming that the nozzle 1 and the container main body 3 are separate bodies, the present invention is not limited to this embodiment, and is, for example, integrally formed. Even if the combination of the nozzle and the container body is a shape that satisfies the equivalent requirements, even if they are separate combinations other than the separation between the nozzle and the container body, The effect of is obtained.

The present invention is not limited to the above embodiment. Those having substantially the same configuration as those described in the claims of the present invention and exhibiting the same functions and effects belong to the technical scope of the present invention.

[0032]

[Effect of the invention]

 As described above, in the present invention, the outlet of the outlet of the liquid container containing the liquid therein or the outlet of the nozzle attached to the outlet gradually reduces the cross-sectional area toward the outlet, and the end of the outlet The narrowest part is formed in the foreground, and a slightly wide part is formed from the narrowest part toward the outlet. Thus, when the container is returned after the liquid is taken out, the liquid slightly remaining at the outlet is drawn into the container and the tip of the outlet is hardly soiled, so that the hermeticity is maintained.

According to the second aspect of the present invention, a detachable cap is provided at the outlet so that the inside of the top of the cap and the tip of the outlet are in close contact with each other when the cap is attached, and there is a space around the outlet that does not adhere to the inside of the cap. I made it. Thus, even if a small amount of liquid adheres to the vicinity of the outlet, the liquid does not spread any more because the area around the outlet does not come into contact with the inside of the cap, so that the hermetic seal can be maintained in a clean state.
