[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a dripping prevention pouring cap used for liquid materials such as dressings and grilled meat sauce that need to be stirred at the time of use, and more specifically, an expanded pouring tube and the pouring tube An upper cover having a seal cylinder that is formed in a liquid reservoir plate having a tip portion inclined inwardly in the dispensing cylinder and is fitted in the dispensing cylinder. The present invention relates to a dripping prevention pouring cap connected to a hinge.
[0002]
[Prior art]
The conventional liquid dripping prevention pouring cap is provided in such a manner that an upper lid e covering the cap main body d, which is provided with a pre-opened opening c, can be opened and closed on a bottom plate b in an expanded pouring tube a. A specially configured liquid dripping prevention mechanism f is provided on the inner surface of the upper lid e. The liquid dripping prevention mechanism f of this special configuration is, for example, a fitting in which a bottom edge that curves inwardly is in liquid-tight pressure contact with an expanded portion g at the tip of a dispensing cylinder a that stands upright from the cap body d. A cylinder h and a plurality of arc-shaped walls i that are suspended in the fitting cylinder h, have a circular arc shape in plan view that protrudes and curves backward, and have a lower end edge that curves in a reduced diameter direction ( JP, 9-12049, A).
[0003]
And according to this liquid dripping prevention pouring cap, when the content liquid is poured after shaking the container and stirring the content liquid, the content liquid adhering to the upper lid e is half of the fitting cylinder h and each circle. Since the arc-shaped wall i faces downward and the lower end edge of the arc-shaped wall i is curved in the direction of diameter reduction, even if the attached content liquid accumulates in the upper lid e, the fitting tube h and each arc-shaped wall i move downward. It can be prevented from dripping.
[0004]
[Problems to be solved by the invention]
However, in the above-described conventional example, the structure of the specially configured liquid dripping prevention mechanism f is complicated, which is difficult in terms of manufacturing and causes an increase in cost. Furthermore, since the structure of the liquid dripping prevention mechanism f is complicated, the remaining content liquid remains attached to the liquid dripping prevention mechanism f and is dried and solidified, so that newly adhering content liquid can be gradually stored. Eventually, when the upper lid e is opened and closed or when the stored liquid is poured out, it hangs out, resulting in a stain around the cap body d.
[0005]
Therefore, the object of the present invention is to have a simple structure and to allow the contents attached in the seal cylinder of the upper lid to hang outside when opening and closing the upper lid and when extracting the contents from the dispensing cylinder. An object of the present invention is to provide a dripping prevention dispensing cap that can be prevented.
[0006]
[Means for Solving the Problems]
The present invention has been proposed in order to achieve the above object, and is characterized by having the following configuration.

When the top lid is opened at a right angle, the vertical line drawn from the top of the liquid reservoir plate is placed in contact with the end of the dispensing cylinder, so that the contents of the container can be opened and closed as well as the contents of the container from the dispensing cylinder. When the object is poured out, it is left in the seal tube or even if it gets over the liquid reservoir, it always flows down into the expanded tube .
The second feature is that the tip of the liquid reservoir plate is in close contact with the inclined surface of the dispensing cylinder when the lid is closed.
The third feature is that a slit is provided at the tip of the liquid reservoir plate.
[0011]
With the feature of this configuration, even if the container is shaken and the contents are agitated, the seal cylinder and the liquid reservoir plate are in close contact with the inner surface of the dispensing cylinder. The contents adhered to the upper lid seal cylinder either flow down into the dispensing cylinder when the upper lid is opened or closed and when the contents are poured out, or left in the seal cylinder. Therefore, it is possible to provide a pouring cap that does not sag outside and can be easily punched after injection molding.
[0012]

A seal cylinder 11 is provided on the bottom plate 8 of the outlet cylinder 7, which can be cut off, and the upper lid 5 is formed in a liquid pool plate 10 whose tip is inclined inward and is fitted into the extraction cylinder 7. When the lid is closed, at least a part of the seal cylinder 11 and the liquid reservoir plate 10 are in close contact with the inner surface 7a of the lower half portion of the dispensing cylinder 7 so that the upper lid 5 is opened and closed and the dispensing cylinder 7 When the contents 12 in the container 2 are poured out from the container 2, the contents 12 adhering in the seal cylinder 11 flow down into the extraction cylinder 7 or are left in the seal cylinder 11.
[0013]
The cap body 4 has an outer cylinder 20, an intermediate cylinder 21, and an inner cylinder 22 provided concentrically at the lower portion thereof, and an annular shape that fits into the mouth 3 of the container 2 between the intermediate cylinder 21 and the inner cylinder 22. When the cap body 4 is fitted to the mouth 3 of the container 2, the outer cylinder 20 hits the outer wall of the mouth 3 to prevent contamination from the outside. The inner cylinder 22 is responsible for passing the contents 12 in the container 2 to the dispensing cylinder 7. On the other hand, the outer cylinder 24, the intermediate cylinder 25, and the extraction cylinder 7 are provided concentrically on the upper part of the cap body 4 like the lower part, and the extraction cylinder 7 is formed in an expanded shape, that is, a trumpet shape. Yes. The lower portion of the pouring cylinder 7 forms an inclined surface 26 that communicates between the inner peripheral surface and the bottom plate 8. The inclined surface 26 plays a role of being closer to the tip of the liquid reservoir plate 10 of the seal cylinder 11 of the upper lid 5 when the lid is closed.
[0014]
The planned opening portion 9 has a finger hook portion 27 and a fragile portion 28 is provided on the bottom plate 8. A finger is put on the finger hook portion 27, and a force is applied to tear the fragile portion 28. 9 is cut out so that the dispensing cylinder 7 and the inner cylinder 22 communicate with each other.
[0015]
The upper lid 5 includes an outer cylinder 31, an intermediate cylinder 32, and the seal cylinder 11 that are concentrically disposed on the top plate 30, and the intermediate cylinder 25 of the cap body 4 is between the intermediate cylinder 32 and the seal cylinder 11. And an annular housing groove 33 for housing the dispensing cylinder 7, covers the dispensing cylinder 7 and the seal cylinder 11, and the outer cylinder 31 is an outer cylinder of the cap body 4 when the upper lid 5 is fitted to the cap body 4. The outer peripheral surface of 24 is hit and the contamination from the outside is prevented. On the other hand, the seal cylinder 11 has a height that can reach the bottom plate 8 of the dispensing cylinder 7 when the lid is closed, and the liquid reservoir plate 10 at the tip thereof is inclined inward as described above.
[0016]
That is, when the upper lid 5 is opened at a right angle from the cap body 4, the perpendicular drawn from the tip of the liquid reservoir plate 10 of the upper lid 5 comes into contact with the end of the trumpet-shaped dispensing cylinder 7 of the cap body 4. . Accordingly, since the liquid reservoir plate 10 is inclined when the upper lid 5 is opened at a right angle, the content 12 can be stored in the liquid reservoir plate 10, and when the upper lid 5 is opened at an acute angle, the liquid reservoir is retained. Since the perpendicular line from the tip of the plate 10 is positioned inside the end of the dispensing cylinder 7, even if the contents 12 flow down from the tip of the liquid reservoir plate 10, it enters the dispensing cylinder 7 and goes outside. There is no leakage.
[0017]
A slit 34 for facilitating removal of the product after injection molding is provided at the tip of the liquid reservoir plate 10. Due to the presence of this slit, even if the molded product is rigid, the slit portion is expanded at the time of mold release, and the product can be easily taken out. Of course, this slit is not necessarily required if the molded product is not rigid. In addition, since the surface tension works in this die-cutting slit 34 part, the liquid content does not leak from this slit.
[0018]
The hinge 6 is provided interposed between the outer peripheral surface of the outer tube 30 of the outer peripheral surface and the upper cover 5 of the outer cylinder 20 of the cap body 4, the structure is adopted conventionally known. The outer cylinder 31 of the upper lid 5 near the hinge 6 is provided with a stopper projection 35 so that even if the upper lid 5 falls down while the contents are being poured out, it does not interfere with the pouring. Further, convex portions 25 a and 32 a are provided on the outer peripheral surface of the intermediate cylinder 25 of the cap body 4 and the inner peripheral surface of the intermediate cylinder 32 of the upper lid 5, so that the upper lid 5 cannot be easily detached from the cap body 4. Yes.
[0019]
Next, the usage method of the extraction | pouring cap 1 which becomes the said structure is demonstrated.
First, the extraction cap 1 before cutting off the planned opening 9 that matches the mouth 3 of the container 2 is selected, and the contents 12 that need to be agitated before use, such as dressing and sagging of grilled meat, in the container 2. The selected extraction cap 1 is fitted into the mouth 3 of the container 2 and shipped as a product. The consumer opens the top cover 5 of the container 2 with the pouring cap 1, puts his finger on the finger hooking portion 27 of the planned opening portion 9, applies a force, tears the fragile portion 28, cuts the planned opening portion 9, and And the inner cylinder 22 are connected, that is, opened. Next, when the container 12 with the pouring cap 1 is sufficiently shaken to stir the container 12, the container 12 is placed inside the top plate 30, the seal cylinder 11, and the liquid reservoir plate 10 of the upper lid 5 as shown in FIG. 5. Adhere to. However, since the seal tube 11 and the liquid reservoir plate 10 are in close contact with the expanded pour tube 7 of the cap body 4, the stored items are placed outside the seal tube 11 and the liquid reservoir plate 10 and inside the pour tube 7. 12 does not adhere.
[0020]
When the upper lid 5 is opened from the cap body 4 in this state, the stored item 12 attached to the top plate 30 flows into the seal cylinder 11 and the liquid reservoir plate 10 and flows down from the tip of the liquid reservoir plate 10. Since the tip is inside the pouring cylinder 7 even when the upper lid 5 is opened to a right angle, the stored item 12 always flows into the pouring cylinder 7. When the upper lid 5 is close to a right angle as shown in FIG. 6, the liquid reservoir plate 10 is inclined inward of the seal cylinder 11, so that the stored item 12 can be stored, and outside the pouring cylinder 7. There is no possibility of the stored item 12 flowing down.
[0021]
In this state, as shown in FIG. 7, when the stored item 12 in the container 2 is poured out from the dispensing cylinder 7, the stored item 12 accumulated in the liquid reservoir plate 10 flows down into the dispensing cylinder 7, and Never go out. Further, in this state, as shown in FIG. 8, when the upper lid 5 is opened to an obtuse angle equal to or greater than a right angle, the state in which the stored matter 12 is accumulated in the liquid reservoir plate 10 is maintained and does not go out. As shown in the figure, when the stored item 12 in the container 2 is poured out from the dispensing cylinder 7 while being further inclined, the stored item 12 accumulated in the liquid reservoir plate 10 flows down into the dispensing tube 7 and is also exposed to the outside. Never leave.
[0022]
As shown in FIG. 10, even if the upper lid 5 is opened only from the cap body 4 to an acute angle, the contents 12 adhering to the top plate 30 flow to the seal cylinder 11 and the liquid reservoir plate 10, and the liquid reservoir plate 10. However, since the flow destination is inside the pouring cylinder 7 even when the upper lid 5 is opened to a right angle, the content 12 always flows into the pouring cylinder 7. In this state, as shown in FIG. 11, when the content 12 in the container 2 is poured out from the dispensing cylinder 7, almost all the contents 12 accumulated in the liquid reservoir plate 10 flow down into the dispensing cylinder 7. , Do not go out.
[0023]
As described above, regardless of the angle at which the upper lid 5 is opened with respect to the cap body 4, the content 12 attached to the seal cylinder 11 and the liquid reservoir plate 10 of the upper lid 5 is removed. In addition, even if the contents 12 in the container 2 are poured out from the dispensing cylinder 7 in each state, the adhered contents 12 may flow down to other than the dispensing cylinder 7. rare.
[0024]
As mentioned above, although embodiment of this invention was described, it cannot be overemphasized that a specific structure is not limited to this but can change a detailed design unless it deviates from the summary of this invention.
[0025]
【The invention's effect】
As described in detail above, according to the present invention, after cutting the planned opening portion, even if the container is shaken and the contents are stirred, the seal cylinder and the liquid reservoir plate are in close contact with the inner surface of the dispensing cylinder. Content that does not adhere to the outside of the seal cylinder of the upper lid is placed in the seal cylinder when the upper lid is opened or closed and when the content is poured out, or the liquid reservoir plate is overcome. However, it always flows down into the expanding pipe and does not sag outside. Therefore, although the structure is simple, it is possible to prevent the contents adhering in the seal cylinder of the upper lid from dripping outside when opening and closing the upper lid and when dispensing the contents from the dispensing cylinder, thus wasting the contents. In addition, there is an effect that the pouring cap can be kept clean without getting dirty.
According to the second aspect of the present invention, even if the liquid reservoir plate is inclined inward, it becomes easy to come into close contact with the inclined surface of the dispensing cylinder, so that the above effect can be made even more remarkable.
Furthermore, according to claim 3 , there is an effect that the upper lid after injection molding can be easily punched.
