Description

  The present invention relates to a dripping prevention pouring cap used for liquids that are prone to dripping, such as dressing and sausage of grilled meat, and more specifically, the liquid content is exposed when the cover cap is opened and closed or poured. The present invention relates to a dripping prevention pouring cap in which the contents liquid does not adhere to the cover cap and the influence is eliminated without sagging the surrounding area.

In a container containing a content liquid such as dressing or grilled meat sauce, the components are usually separated. Therefore, the components are used after thoroughly stirring the components during use. In many cases, such a container containing the content liquid uses a pouring cap formed by hinge-connecting a cover cap so as to be freely opened and closed to a pouring cylinder body attached to the mouth portion. Then, after the container is shaken and stirred sufficiently when the content liquid is used, the cover cap is opened from the dispensing cylinder main body to pour out the content liquid, so that the content liquid adheres to the inside of the cover cap. This adhered content liquid may cause dripping and stain the surroundings, and the content liquid may be wasted. From such a situation, the following is known as a pouring cap for preventing this dripping.
JP-A-9-12049 Japanese Patent Laid-Open No. 2002-2760 JP 2004-352278 A

  As shown in FIG. 6, the dripping prevention pouring cap of Patent Document 1 is provided on a pouring cylinder main body d provided with a planned opening portion c that can be cut out on a bottom plate b in an expanding pouring pipe a. A cover cap e covering this is provided to be openable and closable, and a liquid dripping prevention mechanism f having a special configuration is provided on the inner surface of the cover cap e. As an example, the liquid dripping prevention mechanism f includes an inner ring h in which a lower end edge curved inward is brought into liquid-tight pressure contact with an expanded portion g at the tip of a pouring cylinder a erected from the pouring cylinder body d. And a plurality of arc-shaped walls i that are suspended in the inner ring 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. And according to this 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 cover cap e is half of the inner ring h and each circle. Since the arcuate wall i faces downward and the lower edge of the arcuate wall is curved in the direction of diameter reduction, even if the attached content liquid is accumulated in the cover cap e, it is lowered by the inner ring h and each arcuate wall i. It can prevent drooping.

Further, as shown in FIG. 7, the dripping prevention pouring cap of Patent Document 2 is formed by connecting a cover cap e with a hinge portion j to a pouring cylinder body d attached to the mouth of the container. The cylinder main body d has an opening-like portion c that can be cut off and provided on an expanded dispensing tube a and a bottom plate b of the dispensing tube a.
The cover cap e has an inner ring h that is formed on a liquid reservoir plate k whose tip is inclined inwardly and is fitted into the dispensing cylinder a. When the lid is closed, at least one part of the inner ring h and the liquid reservoir plate k is in close contact with the inner surface of the lower half of the dispensing cylinder a, and the content liquid in the container is poured from the dispensing cylinder a when the cover cap e is opened and closed. In this case, the content liquid B adhering to the inner ring h flows down into the dispensing cylinder a or is left in the inner ring h.

  Further, as shown in FIG. 8, the dripping prevention pouring cap of Patent Document 3 is connected to the pouring cylinder body d attached to the mouth of the container with the cover cap e at the hinge part j, and the pouring cylinder body. When the cover cap e is opened at the upper edge m of the hinged portion j side of the expanded pour-out tube a of d, which is thinner than the other portion of the pour tube a along the circumferential direction of the pour tube a The inner ring h is provided with a tongue piece n that bends while maintaining sliding contact with the outer peripheral surface of the inner ring h. When the cover cap e is opened from the dispensing cylinder body d, the outer peripheral surface of the inner ring h is in sliding contact with the tongue piece n, and even if the content liquid B adheres to the outer peripheral surface, it can be scraped off. , Can flow down into the dispensing cylinder a.

  The dripping prevention pouring cap of Patent Document 1 is difficult in terms of production due to the complicated structure of the dripping prevention mechanism f having a special configuration, and causes an increase in cost. Furthermore, since the structure of the dripping prevention mechanism f is complicated, the remaining content liquid does not return to the dispensing cylinder a, and therefore remains attached to the dripping prevention mechanism f, solidifies, and is newly attached. As a result, the content liquid to be stored cannot be gradually accumulated, and eventually, when the cover cap e is opened / closed or when the content liquid is poured out, the liquid around the dispensing cylinder main body d is soiled.

  Further, the dripping prevention pouring cap of Patent Document 2 can keep the content liquid B in the inner ring h, and can flow down into the pouring cylinder a even if the content liquid B gets over the inner ring h. However, it is convenient, but the inner ring h is higher than the other parts and looks unsatisfactory, resulting in an increase in cost.

Also, the dripping prevention pouring cap of Patent Document 3 can return the content liquid B from the inner ring h into the pouring cylinder a, and even if the content liquid B gets over the inner ring h and is outside, Conveniently, the content liquid B can be scraped off by the piece n and allowed to flow into the dispensing cylinder a, but the inner ring h is higher than the other parts, and the appearance is not good. It can also be a cause. All of the above-mentioned patent documents are based on the premise that the content liquid adheres to the inner surface of the cover cap, and the liquid is collected in the container or prevented from hanging outside. Therefore, the influence of the content liquid adhering to the inner surface of the cover cap cannot be excluded.
As described above, since all of the dripping prevention pouring caps of Patent Documents 1 to 3 have the mouth portion of the container and the pouring cylinder a open upward, the container is moved up and down in order to stir the content liquid. If the liquid is shaken in the direction, the content liquid hits the top plate of the cover cap e, and a force to push the cover cap e to open acts and may open. Therefore, if the cover cap e is strongly locked to deal with it, it will be difficult to open it and the feeling of use will deteriorate.

  Therefore, the object of the present invention is to prevent the contents liquid from dripping outside when the cover cap is opened and closed or poured out, and to prevent the contents liquid from adhering to the cover cap. An object of the present invention is to provide a dripping prevention pouring cap that looks good and can be easily opened and closed, but does not have a risk of accidental opening.

The present invention has been proposed in order to achieve the above object, and is characterized by having the following configuration.
That is, according to the present invention, a main inner member that has a pouring cylinder whose inside is covered with a canopy provided with a pouring outlet and is slidably in contact with the pouring outlet, which is attached to the mouth of the container. An inner inner ring that seals in close contact with the canopy of the main body of the extraction cylinder is provided on the inner side of the ring and the main inner ring, and an auxiliary inner ring that has a tip portion fitted into the extraction cylinder and sealed. A cover cap having a cover cap that is openably and closably connected by a hinge part, and a scraper for scraping off the content liquid adhering to the main inner ring is provided in an adjacent part above the spout. An exit cap is provided.

  According to the present invention, there is also provided the above-mentioned dripping prevention pouring cap in which the main inner ring of the cover cap is provided with vertical ribs for sealing both side ends of the pouring port in the canopy of the pouring tube main body. .

When using the contents of the container, the dripping prevention pouring cap of the present invention shakes the container and agitates the contents, then opens the cover cap from the pouring cylinder main body, passes through the pouring outlet, and from the pouring cylinder. The contents are poured out and used, and at that time, the contents liquid adhering to the main inner ring of the cover cap is blocked when the cover cap is opened. Scraped off by scraper. Therefore, when the cover cap is opened / closed or poured out, the content liquid does not spill outside, and the surroundings are not contaminated. Moreover, since the content liquid does not adhere to the cover cap itself, the influence can be eliminated and the appearance is also kept clean. Furthermore, even if shaken in the vertical direction to stir before dispensing the content liquid, the impact of the content liquid hits the canopy because the spout is in the lateral direction of the canopy and acts directly on the cover cap. Never open. Further, leakage of the content liquid from the spout when the container is shaken and the contents are stirred can be prevented by the innermost inner ring provided inside the main inner ring.

  In addition, the vertical ribs can prevent leakage of the content liquid from both ends of the spout when the container is shaken and the contents are stirred. Therefore, there is an effect of making the above effect even more remarkable.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

FIG. 1 is a longitudinal sectional view of a state in which the dripping prevention pouring cap of the present invention is attached to the mouth of a container, and FIG. 2 is a plan view of the state in which the dripping prevention pouring cap of the present invention is opened. In both figures, a dripping prevention pouring cap 1 has a pouring tube 4 whose inside is covered by a canopy 3 provided with a pouring port 2 and is attached to a pouring tube main body 7 attached to the mouth 6 of the container 5. A main inner ring 8 that slides against and closes the spout 2 and an innermost inner ring 32 that seals and closes the canopy 3 of the pour tube body 7 inside the main inner ring 8; A cover cap 10 having a sub-inner ring 9 whose tip is fitted and sealed in the dispensing cylinder 4 is connected to the hinge portion 11 so that it can be opened and closed. A scraper 12 for scraping off the content liquid A adhering to the ring 8 is provided.

  An outer cylinder 21 is concentrically provided at the lower part of the pouring cylinder body 7 with the top plate 20 as a boundary. A screw 22 is threaded on the inner peripheral surface of the outer cylinder 21, and the mouth portion 6 of the container 5. Screwed in a liquid-tight manner. On the other hand, the outer cylinder 23 and the extraction cylinder 4 are provided concentrically on the top of the top plate 20 of the extraction cylinder body 7, and the extraction cylinder 4 is formed in an expanded shape, that is, a trumpet shape. . There is a step at the upper end of the pouring cylinder 4, the hinge portion 11 side is low, and the pouring port 2 side is high. The outer cylinder 23 is covered with the cover cap 10 and plays a role of preventing internal and external contamination.

  The inside of the pouring cylinder 4 is covered with the canopy 3, and the canopy 3 bulges upward and has a shape in which the heel is turned upside down. The spout 2 is located on the side of the inverted canopy-shaped canopy 3. The scraper 12 is provided on the hill part 24 of the inverted canopy-shaped canopy 3 above the spout 2. The scraper 12 has a function of scraping off the content liquid A adhering to the main inner ring 8 when the cover cap 10 is opened.

  The cover cap 10 includes an outer cylinder 31, the sub-inner ring 9, the main inner ring 8, and the innermost inner ring 32 that are sequentially arranged concentrically from the outside on the top plate 30. As described above, the outer cylinder 31 of the cover cap 10 plays a role of preventing internal and external contamination in cooperation with the outer cylinder 23 of the dispensing cylinder main body 7. The sub-inner ring 9 has a tip portion fitted into the dispensing tube 4 and sealed, so that the content liquid accumulated between the dispensing tube 4 and the spout 2 of the canopy 3 does not leak to the outside. It is for making.

  The main inner ring 8 slidably contacts and closes the spout 2 of the canopy 3, but corresponds to both end portions of the spout 2 in order to completely seal both end portions of the spout 2. The longitudinal ribs 33 are provided at the site of the main inner ring 8 to prevent leakage of the content liquid from both side ends of the spout 2. Further, there is a slight gap between the spout 2 and the main inner ring 8, and there is also a slight gap between the scraper 12. Therefore, it does not leak when the content liquid has a high viscosity, but may leak slightly when it has a low viscosity. Therefore, the innermost inner ring 32 is in contact with the inner peripheral surface 25 of the hill part 24 of the canopy 3 to prevent further flow of the content liquid.

  As shown in FIGS. 1 and 2, the hinge portion 11 is formed to be thin and is connected to the dispensing cylinder body 7 and the cover cap 10 so as to be freely opened and closed.

Next, the usage method of the dripping prevention pouring cap 1 which becomes the said structure is explained in full detail.
When the container 5 filled with the contents liquid that needs to be agitated before use such as dressing and grilled meat is shaken well before opening, the contents of the canopy 3 and the canopy 3 and this can be obtained as shown by the shaded area in FIG. The content liquid A adheres to the inner surface of the pouring cylinder 4 covered with and the main inner ring 8 in the portion slidingly contacting and closing the pouring port 2. Moreover, since most of the impact is absorbed by the canopy 3 when the content liquid is agitated and does not act directly on the cover cap 10, it does not open accidentally.

  As shown in FIG. 4, when the cover cap 10 is opened from the dispensing cylinder body 7, the scraper 12 provided on the hill portion 24 of the canopy 3 removes the content liquid A adhering to the main inner ring 8 from the scraper 12. Will return to 5. When the cover cap 10 is further opened as shown in FIG. 4, the content liquid A adhering to the main inner ring 8 is completely scraped off by the scraper 12 and returned to the container 5. Further, when the cover cap 10 is in the state shown in FIG. 5, the portion of the main inner ring 8 that slides on and closes the spout 2 opens completely away from the spout 2, so that the container 5 can be tilted. For example, the content liquid can be used after being poured out from the pouring end of the pouring tube 4 through the pouring port 2. At this time, since all of the attached content liquid A is in a portion directly connected to the inside of the container 5, the attached content liquid A does not sag outside and stain the surroundings.

  Although the first embodiment of the present invention has been described above, it should be understood that the specific configuration is not limited to this, and that changes can be made as appropriate without departing from the scope of the present invention.

  The present invention is a case where the ingredients are separated with high viscosity such as dressing or grilled meat sauce, and the container is used after the container is shaken sufficiently. Use when there is a risk of dripping and soiling the surrounding area, or when the cover cap may be accidentally opened, especially when it looks good and you want to eliminate the effects of the liquid content on the cover cap side The possibility is extremely high.
