Description

The present invention relates to a pouring cap attached to a container and a container equipped with the pouring cap.

A structure in which a pouring cap having a pouring tube is attached to a container is conventionally known. When dispensing the contents contained in the container, the contents are poured out from the dispensing tube by tilting the container with the dispensing tube provided on the dispensing cap open. Furthermore, when dispensing the contents, the container is returned to its original position (such as an upright position) and the dispensing tube is closed.

It is already widely known that such containers are deformable. For example, so-called PET bottles, other resin containers, and other bag-like containers called pouches are already widely known. In such a deformable container, when dispensing the contents inside the container, tilt the container with the dispensing tube open and press the container with your finger or palm to deform it. The contents are being poured out from the pouring tube.

Note that a pouring cap attached to a container is disclosed in, for example, Patent Document 1. Furthermore, a structure in which a pouring cap called a spout is attached to a bag-like container called a pouch is disclosed in Patent Document 2, for example.

However, with conventional dispensing caps, when the container is tilted to dispense the contents, the contents may come out excessively or a portion of the contents may remain in the dispensing tube and drip ( (so-called dripping) may occur. If some of the contents remain on the outside of the spout and drip, there is a risk that the dripped contents from the spout will fall onto your fingers or clothes, staining them. Furthermore, when the container is deformable, such problems are more likely to occur.

The present invention solves the above-mentioned problems, and has a dispensing cap that can prevent the contents from coming out excessively when dispensing the contents from the container, and can also suppress the contents from remaining on the outside or inside of the dispensing tube. The purpose is to provide containers and containers.

In order to solve the above problems, the spouting cap of the present invention includes a main body that is attached to a container in which contents are stored and has a spouting tube, and a spouting tube that is rotatable with respect to the spouting tube. It is equipped with an outer cap attached to the outside of the pipe, and a screw that rotates inside the spout tube in conjunction with the outer cap. The dispensing tube is formed in an inclined position, and is configured such that when the outer cap is rotated in a predetermined direction, a screw is coupled to push the contents inside the dispensing tube back into the container.

According to this configuration, since the rotatable screw is disposed inside the pouring tube, even when the container is tilted or the deformable container is deformed in order to take out the contents from the container, the contents can be easily removed. The screw prevents the material from coming out in excess. In addition, by rotating the outer cap in a predetermined direction after pouring out the contents, the screws will work together to push the contents inside the dispensing tube back into the container. You can prevent things from remaining behind.

In the pouring cap of the present invention, it is preferable that the outer cap and the screw are connected or integrally formed so as to rotate together. Further, in the pouring cap of the present invention, it is preferable that a nozzle for dispensing the contents is provided on the outer cap, and a nozzle cover cap that covers this nozzle is provided on the outer cap in a detachable manner.

The present invention also provides a container equipped with any of the above-mentioned pouring caps, which is deformable, and which returns from a deformed state where the internal capacity is reduced to an original state where the internal capacity is increased. It is characterized by having almost no back function. For example, this applies when the container is a pouch.

In this way, if the container has almost no suck-back function, the contents remaining in the dispensing tube will not return to the container immediately after the contents are taken out of the dispensing tube, so that some of the contents will not return to the container. A portion of the liquid remains in the spouting tube and drips, making it easy to cause so-called dripping. However, according to this configuration, by rotating the outer cap in a predetermined direction, the contents inside the spout tube are pushed back into the inside of the container, so it is possible to prevent the contents from remaining on the outside or inside of the spout tube. .

Note that this pouring cap may be provided when the container is deformable and has a suck-back function that returns from the deformed state where the internal capacity is reduced to the original state where the internal capacity is increased. .

According to the pouring cap of the present invention, the outer cap is rotatably attached to the outside of the pouring tube with respect to the pouring tube of the main body, and the outer cap is attached to the inside of the pouring tube in conjunction with the outer cap. A rotating screw is provided, the screw is formed in an attitude that is inclined up and down with respect to the circumferential direction around the rotation center, and the contents in the dispensing tube are poured by rotating the outer cap in a predetermined direction. By being configured to push back into the container, the screw prevents the contents from coming out excessively even when the container is tilted or the deformable container is deformed in order to remove the contents from the container. This makes it easy to use. In addition, by rotating the outer cap in a predetermined direction after pouring out the contents, the contents inside the dispensing tube are pushed back into the container, so there is no possibility that the contents will remain on the outside or inside of the dispensing tube. Minimizes the possibility that some of the contents may remain on the outside of the dispensing tube and drip, resulting in the contents dripping from the dispensing tube falling onto your fingers or clothes, staining your fingers or clothes. be able to.

EMBODIMENT OF THE INVENTION Hereinafter, the pouring cap and container of embodiment based on this invention are demonstrated based on drawing.
In FIGS. 1 to 12, reference numeral 1 denotes a pouring cap attached to a container 2 in which contents (content liquid) are stored. Note that in FIGS. 1 to 11, the case where the container 2 is a pouch is shown. However, the present invention is not limited to this, and FIG. 12 shows a case where the container 2 is not a pouch but a general container (so-called PET bottle or other container (other than a pouch)) 2.

As shown in FIGS. 1 to 3, a spouting cap 1 is attached to a container 2 containing semi-solid, muddy, liquid, etc. contents, and has a spouting tube 3, etc. A main body) 4, an outer cap 6 which is attached to the outside of the spouting tube 3 in a rotatable state relative to the spouting tube 3 and is provided with a nozzle 5 for dispensing the contents; It includes a screw (rotating blade) 7 that rotates inside the spouting tube 3, and a nozzle cover cap 8 that covers the nozzle 5.

In this embodiment, the container 2 is formed by thermally welding the peripheries of two deformable front and back flexible sheets and one bottom flexible sheet made of, for example, synthetic resin. The pouch is made up of a sealed (sealed) pouch, and is, for example, rectangular (substantially rectangular) when viewed from the front, but is not limited to this.

The main body 4 of the spouting cap 1 is a so-called spout, and as shown in FIGS. 1 to 4, the main body 4 of the spouting cap 1 is sandwiched between two flexible sheets at the top of the container 2. Heat welded. A container mounting portion 9 having a plurality of welding ribs 9a that is welded to the main body 4 is provided at the lower part of the main body 4, and a pouring tube 3 is integrally formed so as to stand up from the container mounting portion 9. has been done. In addition, the spouting cap 1 is welded to the center of the upper side of the container 2 with the axis X direction of the spouting tube 3 (see FIGS. 4 and 7) facing upward with respect to the container 2. It has been installed.

In this embodiment, as shown in FIG. 4, FIG. 6, and FIG. Although the spouting tube 3 is erected so as to extend vertically from the periphery, the spouting tube 3 is not limited to this, and the spouting tube 3 can be directly installed from the main body 4 of the spouting cap 1 without providing the large diameter tube portion 10. may be erected.

As shown in FIGS. 4, 6 to 9, etc., the outer cap 6 includes a rotary cylinder part 6a that is attached to the outside of the spout cylinder 3 in a rotatable state with respect to the spout cylinder 3, and a rotary cylinder part 6a that is rotatably attached to the outside of the spout cylinder 3. It has a nozzle 5 that extends upward from the top of the container 6a and pours out the contents. In this embodiment, a small diameter part 6b and an inner small diameter part 6e (see FIGS. 6 and 7), which have a slightly smaller diameter, are provided in the upper part of the rotating cylinder part 6a. The portion 6b and the inner narrow diameter portion 6e are rotatably fitted into the upper end of the pouring tube 3 from the outer circumferential side, the upper side, and the inner circumferential side. Further, on the outer periphery of the region below the narrow diameter portion 6b of the rotary cylinder portion 6a, a plurality of outer periphery uneven stripes (so-called knurls) are continuous in the circumferential direction so that the outer cap 6 can be easily rotated with fingers. It is formed by Further, in this embodiment, the lower part of the rotary cylinder part 6a is rotatably attached to the large-diameter cylinder part 10 from the outer periphery, and protrudes outward from the lower outer periphery of the large-diameter cylinder part 10 so as to rotate. Although a protruding rib 10a is also formed to restrict the downward movement position of the cylindrical portion 6a, the present invention is not limited thereto.

The nozzle 5 of the outer cap 6 is formed to become thinner from the upper inner periphery of the narrow diameter portion 6b toward the upper end. Further, on the inner periphery of the nozzle 5 of the outer cap 6, a plurality of connecting arms 6c are provided at predetermined angles in the circumferential direction and extend diagonally downward toward the axis of the spouting tube 3 (this embodiment In this case, a total of three locations are provided every 120 degrees in the circumferential direction). Further, the lower end portions of these connecting arms 6c form a connecting ring portion 6d connected in a ring shape. A screw 7 is coupled to the outer cap 6 via the coupling arm 6c and the coupling ring portion 6d so as to rotate together with the outer cap 6. In addition, the screw 7 and the connecting ring part 6d may have an uneven part that is recessed or protruded in the radial direction on the joint surface in the circumferential direction, or the joint surfaces in the circumferential direction may be thermally welded or bonded. It may also be fixed through a material.

As shown in FIGS. 4, 6 to 7, 10, and 11, the screw 7 is composed of a shaft portion 7a and a blade portion 7b, and the upper end of the shaft portion 7a is connected to the connecting ring portion 6d of the outer cap 6. The screw 7 is connected to the outer cap 6 so that the screw 7 rotates together with the outer cap 6. Furthermore, at the lower end of the spouting tube 3, a plurality of rotary support arms 11 are provided at predetermined angles in the circumferential direction and extend radially inward toward the axis X of the spouting tube 3 (in this embodiment). In this form, there are a total of three locations at intervals of 120 degrees in the circumferential direction). The center portions of these rotary support arms 11 are connected in a ring shape to form a support ring portion 12, and the lower end portion of the shaft portion 7a of the screw 7 is rotatably supported by the support ring portion 12. Gaps are formed between adjacent connecting arms 6c and between adjacent rotary support arms 11, and the contents in the container 2 can pass through the gaps between these. Further, in this embodiment, an upper collar portion 7c that contacts or approaches the connecting ring portion 6d from below is formed near the upper end of the shaft portion 7a, and the support ring portion 12 is formed near the lower end of the shaft portion 7a. Although a lower flange portion 7d is formed that slides into contact with the lower flange portion 7d from above, the present invention is not limited thereto. Further, in this embodiment, the upper end and the lower end of the shaft portion 7a have a smaller diameter than the central portion between them, but the diameter is not limited to this.

As shown in FIGS. 10, 11, etc., the blade portion 7b of the screw 7 is formed to be inclined vertically with respect to the circumferential direction around the shaft portion 7a, which is the center of rotation. When the outer cap 6 is rotated in a predetermined direction, the contents inside the spout tube 3 (the contents around the screw 7) are pushed back into the inside of the container 2. In this embodiment, two semicircular blade portions 7b are integrally formed with the shaft portion 7a in a vertically inclined posture. For example, by rotating the outer cap 6 clockwise in plan view, the screw 7 is also rotated clockwise together with the outer cap 6, and the contents inside the spouting tube 3 (that is, the contents around the screw 7) are rotated clockwise together with the outer cap 6. (in other words, the contents at the tip of the dispensing tube 3 are pushed back to the proximal end (lower end) of the dispensing tube 3 and the inside of the container 2). Note that the shape and number of the blade portions 7b of the screw 7 are not limited to the above-mentioned shapes, and may have three or more blade portions 7b, or may have a continuous spiral shape in a ribbon shape. At least a part of the blade portion 7b has a shape inclined with respect to the circumferential direction, and when the screw 7 is interlocked with the rotation of the outer cap 6, the contents in the spouting tube 3 are transferred to the container 2. It suffices if it has the effect of pushing it back inside.

Further, as shown in FIGS. 4, 6, etc., the nozzle cover cap 8 that covers the nozzle 5 includes a disk-shaped top surface portion 8a, and extends downward in a cylindrical shape from a central portion of the bottom surface of the top surface portion 8a. an inner cylinder part 8b that contacts the inner peripheral surface of the nozzle 5 and covers the nozzle 5; and an outer part that extends downward in a cylindrical shape from a location near the outer periphery on the lower surface of the top surface part 8a and that can be covered with the narrow diameter part 6b of the outer cap 6 from the outer periphery. It has a cylindrical portion 8c. The outer cap 6 can be attached to and detached from the nozzle 5 and the narrow diameter portion 6b.

In the above configuration, when dispensing the contents in the container 2, the internal capacity of the container 2 is reduced by deforming the container 2 by crushing it with your hand or fingers with the nozzle cover cap 8 removed. Transform it to become smaller. At this time, if there is nothing inside the spout tube 3, the contents may come out excessively or some of the contents may remain in the spout tube and drip. There was a risk that the contents would fall onto fingers or clothes, staining them.

On the other hand, in the pouring cap 1 of the present invention, since the rotatable screw 7 is disposed inside the pouring tube 3, the container 2 cannot be deformed in order to take out the contents from the container 2. The screw 7 prevents the contents from coming out excessively or suddenly even when the contents are in use. In addition, it is possible to reduce the possibility that some of the contents may remain in the spout tube 3 and drip, resulting in the contents dripping from the spout tube 3 falling onto fingers or clothing, staining the fingers or clothes. . This improves usability.

After pouring out the contents, a person holding the container 2 or the like rotates the outer cap 6 in a predetermined direction (in this embodiment, clockwise in plan view), and the screw 7 is screwed together with the outer cap 6. are linked and rotated in the same direction. Thereby, the contents in the spouting tube 3 (the contents around the screw 7) are pushed back into the container 2, and it can be suppressed that the contents remain on the outside or inside of the spouting tube 3. Therefore, it is possible to minimize the possibility that some of the contents may remain in the spouting tube 3 and dripping, and the contents dripping from the spouting tube 3 may fall onto your fingers or clothes, staining your fingers or clothes. It can be suppressed.

Further, as described above, when the container 2 is a pouch, the container 2 is deformable, and the sack bag returns from the deformed state so that the internal capacity becomes smaller to the original state so that the internal capacity increases. It has almost no function. Therefore, as described above, when the container 2 has a property such as a pouch that has almost no suck-back function, if there is nothing in the dispensing cylinder 3, when dispensing the contents, If too much content comes out or some of the content remains in the dispensing tube and drips, the contents dripping from the dispensing tube may fall onto your fingers or clothes, staining your fingers or clothes. Furthermore, after pouring out the contents, a portion of the contents may remain in the pouring tube and drip, resulting in similar problems. On the other hand, according to the present invention, since the rotatable screw 7 is disposed inside the pouring tube 3, the above-mentioned problems can be better improved and minimized. .

Further, in the above embodiment, the container 2 has a property such as a pouch that almost does not have a suck-back function, but the present invention is not limited to this. In other words, the container 2 is a general container (a so-called PET bottle or other container (other than a pouch)) 2, and is deformable, and the internal capacity can be changed from a state in which the internal capacity is reduced. It may be a container that has a suck-back function that returns to its original state in an increasing manner (another embodiment).

In this case, as shown in FIG. 12, it is preferable that the main body 4 itself having the spout tube 3 is attached to the mouth 2a of the container 2, but the present invention is not limited to this. Any structure is acceptable as long as the cap 1 can be attached to the container 2.

Further, as described above, it is preferable that the outer cap 6 and the screw 7 are configured to integrally interlock with each other because the structure is simple. However, the invention is not limited to this, and for example, an interlocking mechanism such as a gear mechanism may be interposed between the outer cap 6 and the screw 7, so that the outer cap 6 and the screw 7 integrally interlock at different rotation speeds. It may be configured as follows.

Further, in the above embodiment, the case where the outer cap 6 and the nozzle cover cap 8 are separate bodies is illustrated, but the present invention is not limited to this, and the outer cap 6 and the nozzle cover cap 8 are connected via a hinge. They may be connected so that they can be opened and closed.

In addition, it is particularly preferable that the contents have a high viscosity, and by rotating the outer cap 6 in a predetermined direction, the contents in the dispensing tube 3 can be transferred into the container 2. It has the advantage of being able to be pushed back well. However, the present invention is not limited to this, and can also be applied to a container 2 containing contents with low viscosity.
