Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pouring tool for a paper container having an attachment hole on an upper inclined surface, and has a spout and an unauthorized opening preventing function to be screwed to the pouring opening, and is completely closed even after opening. It is related with the extraction tool for paper containers which consisted of the cap which can respond to the size reduction of the cap by the height regulation derived from the shape of a paper container.
[0002]
[Prior art]
When a paper container is used as a container for food and drink, first, a spout is provided in a mounting hole opened at the top of the paper container, and a cap is attached to the spout. The set consists of a pouring tool. The cap of the pouring tool has a pilfer proof characteristic, that is, a function of preventing the tampering of the contents of the paper container with respect to food and drink, and the cap is completely attached and sealed after the cap is removed from the spout. It is mainstream to be able to do it. Caps with this pilfer-proof property can be made of either plastic or metal in terms of material, but the plastic outlets that are directly attached to paper containers have better mounting properties. It is made.
[0003]
As shown in FIG. 9, such a pouring tool a such as a plastic paper container has a spout b and a ring body e that continues to the cap body c via a fragile portion d that breaks when opened. The cap body c is screwed into the outlet b and the cap f is attached to the ring body e. The integral outlet b and cap f are passed through the mounting hole h from the inside of the container g, and the outlet b Are attached to the attachment hole h by welding.
[0004]
And the pouring tool a, such as a paper container, turns the cap body c in the opening direction, breaks the fragile portion d to release from the ring body e, and further turns to remove the cap body c from the spout b. Thereafter, if the spout b has an inner lid j, the inner lid j can be removed to use the contents of the container g. And when the contents of the container g remain, if the cap main body c is attached to the spout b again, the inside of the container g can be sealed. Therefore, unless the cap body c is detached from the ring body e, the container g cannot be opened, and the cap body c is detached from the ring body e means that the dispensing tool a has already been opened. This guarantees the pilfer proof characteristics. Further, when the cap f is attached to the spout b, even if the cap f is turned in the closing direction, the ratchet locking piece k of the ring body e gets over the protrusion l of the spout b and the fragile portion d is not broken. The ring body e is rotated together with the cap body c, the cap body c is screwed to the spout b, and the ring body e is mounted to the spout b.
[0005]
[Problems to be solved by the invention]
However, since the pouring tool a such as a paper container in FIG. 9 is attached in an oblique direction of the container g, the pouring tool a cannot be protruded from the line A for storage of the container g due to restrictions during loading. I have to make it small. Therefore, when attaching the cap f to the spout b, the ratchet locking piece k, which is easy to miniaturize, is adopted to rotate the ring body e together with the cap body c. It is designed to be locked with the six protrusions 1 of the spout b in the direction. In addition, since the spout b is made of polyethylene, which is a relatively soft material, in consideration of breakage of the fragile portion at the time of molding and opening of the pull ring, the ratchet locking piece k is removed from the protrusion l at the time of opening. There is a risk that the function of preventing unauthorized opening will be damaged.
[0006]
Moreover, since this pouring tool a must be small, the cap f is also small, and the user may lack smoothness in opening and closing the cap. Furthermore, after removing the cap main body c from the spout b, the inner lid j is also small and difficult to remove, which may make it difficult to open with fingers.
[0007]
Therefore, the object of the present invention is to easily open and close the cap even if the size is regulated and is small because of the shape of the paper container having the mounting hole for the pouring tool on the upper inclined surface . An object of the present invention is to provide a pouring tool such as a paper container in which the inner lid can be easily opened and the ring body does not come off.

[0011]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a longitudinal sectional view of a dispensing tool such as a paper container showing an embodiment of the present invention. As shown in FIG. 8, the pouring tool of the present invention is attached to the attachment hole on the inclined surface above the paper container, and is formed of plastic.
In the figure, a paper container pouring tool 1 has a spout 2 and a ring body 5 connected to a cap main body 3 via a weakened portion 4 that is broken when the cap is opened, and the cap main body 3 is screwed into the spout 2. And a cap 6 on which the ring body 5 is mounted. The cap body 3 is attached to the mounting hole 8 of the container 7 through the inner side of the container 7, and the cap body 3 is located between the top plate 9 and the side wall 10. Are provided with inclined walls 11, and continuous vertical grooves 12 are provided from the upper ends of the inclined walls 11 to the side walls 10. The vertical grooves function as a slip stopper when the cap is opened and closed, and are formed into a paper container shape. This corresponds to the size reduction of the cap 6 due to the height regulation derived from it.
[0012]
This note Daegu 1 for a paper container, but mainly Ru is used in a paper container, and more can also be used in bag-in-box. Therefore, the spout 2 for attaching to containers 7, such as a paper container and a bag in box, is needed. The spout 2 is provided with a flange 21 for welding to the mounting hole 8 of the container 7 at one end of the cylindrical body 20, slightly above the flange 21, that is, above the thickness corresponding to the component material of the container 7, A protrusion 22 for temporarily fixing the dispensing tool 1 before welding to the mounting hole 8 is provided. The protrusion 22 is tapered so that the attachment hole 8 can be easily passed. Furthermore, there is a screw thread 23 for screwing the cap 6 on the outer peripheral surface of the cylindrical body 20, and an annular locking protrusion 24 described later is provided between the screw thread 23 and the protrusion 22. The spout 2 has an internal lid 27 with a pull ring 26 that can be opened by the fragile portion 25, and the finger hook 28 side of the pull ring 26 is curved in the spout direction of the spout 2.
[0013]
The degree of curvature, as shown in FIG. 2, good degree protrude from the upper end of the tubular body 20 by utilizing the properties of the plastic, and easily over the finger on the finger hook portion 28 in this manner. Further, since the linear slip stopper 28a is provided on the inner surface of the finger hook portion 28, it is easy to put a finger on the inner surface of the finger hook portion 28, and the pulling force of the finger is transmitted to the pull ring 26 without slipping by the slip stopper 28a. The fragile portion 25 is broken and the inner lid 27 can be easily removed. As shown in FIG. 4, the fragile portion 25 has a V-shaped portion 25 a where the force transmitted to the pull ring 26 is first applied so that the fragile portion 25 is easily broken.
[0014]
As described above, the cap 6 is integrated with the ring body 5 through the fragile portion 4 separable from the cap body 3. A thread 30 corresponding to the thread 23 of the cylindrical body 20 of the spout 2 is formed on the inner peripheral surface of the cap body 3. A stopper 31 is provided on the end face of the cap body 3 on the ring body 5 side, and a stopper 32 corresponding to the stopper 31 is also provided on the ring body 5. When the cap 6 is screwed into the cylindrical body 20 of the spout 2, these stoppers 31 are attached. , 32 are brought into contact with each other so that the fragile portion 4 is not broken.
[0015]
The ring body 5 includes a plurality of locking pieces, in the example shown in FIG. 7, eight flexible locking pieces 40 protruding upward, over the entire circumference of the cap body 3 side. 5 is provided so as to be rotatable toward the inside. Therefore, when the cap 6 is screwed into the cylindrical body 20 of the spout 2 and the tip of the locking piece 40 of the ring body 5 is deformed outward and once exceeds the annular locking projection 24 of the cylindrical body 20. By restoring, the locking piece 40 can be locked to the locking projection 24, and when the cap body 3 is removed from the cylindrical body 20, the fragile portion 4 is not broken and the cap 6 does not come off. That is, the flexible locking piece 40 projecting inwardly upward has a high locking strength in the axial direction of the ring body 5 and is convenient for preventing the ring body 5 from coming off. At this time, if the latching piece 40 is a ratchet latching piece k as in the conventional example, the ratchet latching piece k and the projection l cannot be removed greatly, and the material is soft polyethylene, so that the brittle part is opened. There is a possibility that the cap f may come off without being broken.
[0016]
As described above, in order to prevent the ring body 5 from coming off from the cylindrical body 20, the ratchet piece k is not adopted, and the locking piece 40 is slightly raised to be locked in the axial direction. Accordingly, the height of the cap body 3 needs to be lowered. Further, when the container 7 is a paper container as shown in FIG. 8 and the pouring tool 1 is obliquely installed on the upper part thereof, the cap 6 comes out from the line A from the side of the container. Not allowed for storage or transportation of paper containers. Therefore, from such a situation, the cap body 3 has been made to have a reduced height dimension, and further to provide an inclined wall between the top plate and the side wall so as to form a truncated cone as a whole . If it does in this way, since it will become difficult to open the cap main body 3 because it is low, it will be difficult to open the cap main body 3, and the slip stopper 12 is provided on the side wall 10 and the inclined wall 11 of the cap main body 3 to eliminate these problems. In addition, by making the cap main body 3 into a truncated cone shape as a whole, the cap body 3 can be smoothly passed through the mounting hole 8 of the container 7.
[0017]
In addition, since the cap main body 3 is downsized in this way, the pull ring 26 that removes the inner lid 27 is also small, so it is difficult to hook a finger, and the finger hooking portion 28 side is curved in the pouring direction of the spout 2. This is addressed.
Further, the material of the spout 2 and the cap 6 is plastic, and the spout 2 is preferably a polyethylene which is a relatively soft material in consideration of breakage of the weak part at the time of forming and opening the pull ring. The cap 6 is preferably a polyolefin type, but may be other plastics.
[0018]
Next, the function of the dispensing tool 1 for paper containers having the above-described configuration will be described.
First, a paper container 7 is selected, a spout 2 and a cap 6 that fit into the mounting hole 8 formed on the upper inclined surface of the container 7 are selected, and the cap 6 is screwed into the spout 2; This is performed until the locking piece 40 of the ring body 5 exceeds the locking projection 24 of the cylindrical body 20 and is screwed together to form the pouring tool 1. On the other hand, the container 7 is assembled, the pouring tool 1 is passed through the mounting hole 8 from the inside, and the pouring tool 1 is temporarily fixed to the mounting hole 8 beyond the protrusion 22. At this time, since the cap body 3 has a truncated cone shape and the protrusion 22 has a tapered upper surface, the pouring tool 1 can be easily passed through the mounting hole 8. In this temporarily fixed state, the flange 21 of the cap 6 is welded to the laminated portion of the mounting hole 8 by high frequency.
[0019]
The container 7 in this state is filled with the contents and sealed to obtain a final product. This final product is consumed by the end user. When consuming, the end user first puts his / her finger on the longitudinal groove 12 continuously provided from the upper end of the inclined wall 11 of the cap body 3 to the side wall 10 and turns it in the opening direction. The cap body 3 can be smoothly rotated in the opening direction by the vertical groove 12, and the cap body 3 can be removed while the weakened portion 4 is broken and the ring body 5 remains in the cylindrical body 20. Thereafter, the inner lid 27 can be easily removed by placing a finger on the slip stopper 28a on the inner surface of the finger hook portion 28 of the pull ring 26 and pulling it. When the contents of the container 7 are used and the contents cannot be used, the cap body 3 can be screwed again into the cylindrical body 20 of the spout 2 to seal the container 7.
[0020]
As mentioned above, although embodiment of this invention was described, a specific structure is not limited to this.
[0021]
【The invention's effect】
As described in detail above, according to the present invention, the cap can be easily opened and closed by utilizing the anti-slip function of the longitudinal groove continuously provided from the upper end of the inclined wall of the cap body to the side wall. The fragile portion can be broken and detached from the ring body, and the cap body can be removed from the spout to make the contents of the container available. Further, in closing the cap, the container is sealed by screwing the cap body into the spout, utilizing the anti-slip function of the longitudinal groove continuously provided from the upper end of the inclined wall to the side wall.
Therefore, even if the size of the cap body is regulated and reduced in size due to the shape of the paper container in which the pouring tool is attached to the mounting hole formed in the upper inclined surface, the ring that reduces the size of the cap body The body can be raised, so that it is possible to provide the ring body with a flexible locking piece that protrudes inwardly upward, and the cap without breaking the fragile portion when opening There is an effect that can be eliminated.
[0022]
In addition, according to the present invention, after removing the cap body from the spout as described above, the finger hook side of the pull ring is curved so as to protrude from the end of the cylindrical body in the spout direction of the spout, By pulling and pulling your finger immediately on the finger-hanging part, you can break the fragile part and remove the inner lid, and even if you make the cap small, you can hang your finger on the finger-hanging part without hindrance, making the inner lid easy There is an effect that can be removed.
In addition, once the locking piece gets over the locking projection in the process of attaching the cap to the spout, the locking piece will hit the locking projection and the ring body will not come off. There is an effect that can be eliminated.
