Description

The present invention relates to a pouring container that stores and dispenses liquids such as shampoos, conditioners, liquid detergents, and toiletry products such as fabric softeners.

As the container for storing liquids such as toiletry products such as liquid detergents and fabric softeners, special pouring containers having an easy-to-use shape, for example, plastic bottles and glass bottles, are used.
These pouring containers have an overcap that can be used as a measuring cup that makes the contents visible, and a pouring cylinder and a return port that are easy to pour and easily return the excess contents to the container. It is equipped with a cap that also serves as a container, and has a solid structure, making it an expensive container.
For this reason, a refill pouch that can be filled so that it can be used repeatedly when the contents are exhausted in the dedicated pouring container and the contents are refilled in the pouring container is sold separately and can be easily filled. It is used as a combination of easy-to-use refill containers.

However, since these dispensing containers are designed so that the contents can be easily dispensed, the convenience of the refilling operation of refilling the contents from the refilling pouch is not always taken into consideration.
In particular, the opening for filling the spout is made of a thin film and is easily deformed, and the spouting cylinder protrudes in the center, so that the contents are poured into a slight gap on the outside of the spouting cylinder. , There was a problem that it leaked to the outside and polluted the surroundings.

Therefore, the refill pouch can be easily and safely refilled into the dispensing container, and at the same time, in order to obtain a dispensing container in which the contents can be easily dispensed, the contents that are easy to dispense and the contents that have been excessively dispensed can be placed in the container. A pouring container has been developed that has a cap that doubles as a refilling cylinder and a refilling port.

For example, in Patent Document 1, a stopper in a stopper in which a tubular nozzle portion of a container is fitted into the groove portion of a stopper type cap having a groove formed by an inner wall and an outer wall having an undercut on the inner peripheral surface. It has a pressure-supporting structure, and the outer peripheral surface of the tubular nozzle portion goes around the outer peripheral surface once, and the outward annular protrusion for fitting the plug-type cap and the annular groove for engaging the stopper holder are coaxial. A straight line formed at intervals in a shape and parallel to the axial direction from the end surface of the nozzle portion toward the annular groove portion is the total length of the wall connecting the outward annular protrusion portion and the annular groove portion in the nozzle portion. An inward annular protrusion is formed on the inner peripheral surface of the nozzle portion in the vicinity of the outward annular protrusion so as to pass through the wall thickness, and the outward annular protrusion abuts on the outer cylinder. In a state where the inward annular protrusion is in contact with the inner cylinder, the line segment connecting the two contact points is the meat of the wall connecting the outward annular protrusion and the inward annular protrusion of the nozzle portion. We are proposing a plug pressure support structure in a container nozzle portion that is configured to be included in the thickness.

However, since the tubular nozzle portion protrudes to the center and the annular groove portion is narrow, it is difficult to hold the spout of the soft refill packaging bag in the annular groove portion for a long time, and with detergent or the like, A film like a soap bubble is stretched around the filling, making it easy to create a state where it does not go inside. Further, even if an attempt is made to remove the nozzle portion, there is a problem that it is not easy to use, for example, because it is a plug-type cap, a very large force is required to remove it.

Further, in Patent Document 2,
A container with a cap including a bottomed tubular container and a cap attached to the mouth of the container.
The cap is detachably screwed to the mouth of the container and has a spout, an overcap that is detachably screwed to the spout cap and covers the spout, and the pouring cap. And a regulatory section that engages with the container and regulates movement of at least the loose side along the relative cap circumferential direction of the two.
The regulating portion is provided so as to be slidably movable in the cap axial direction with respect to the pouring cap and the container, and is engaged with the container when slided to the overcap side along the cap axial direction. Released,
A first engaging groove extending in the axial direction of the cap is formed in either one of the dispensing cap and the regulating portion, and the other is engaged with the first engaging groove and described above. A first engaging convex portion that regulates bidirectional movement along the relative cap circumferential direction between the injection cap and the restricting portion is provided so as to project.
A second engaging groove extending in the cap axial direction is formed in either one of the container and the regulating portion, and the other is engaged with the second engaging groove and is engaged with the container. A second engaging convex portion that regulates bidirectional movement along the circumferential direction of the cap relative to the restricting portion is provided so as to project.
When the second engaging groove is open in the cap axial direction and the restricting portion is slid toward the overcap side along the cap axial direction, the second engaging convex portion is moved to the second engaging convex portion. We have proposed a container with a cap, which is characterized in that the engagement between the restricting portion and the container is released by pulling out from the engaging recess in the direction of the cap axis.

In this container with a cap, the regulation part that regulates the rotation of the pouring cap is moved upward to release the regulation, but even when the container is not in use, such as during transportation, it is easily released by vibration or the like. There was a risk that the pouring cap would loosen and the contents would leak.

Jitsukaisho 62-38830 Japanese Patent No. 5193726

Therefore, in the present invention, the cap having the dispensing cylinder can be removed at the time of refilling, but when the cap covering the dispensing cylinder is used during transportation or the like, the opening is stopped and the dispensing container is surely prevented from leaking. Obtaining is an object of the present invention.

The restraining parts are inserted into the locking projection of the dispensing cap to stop the rotation, and the restraining parts are fitted into the biting portion of the opening of the container body near the lower end to prevent the rotation of the dispensing cap. It has an occlusal process that allows it,
When the overcap is attached to the dispensing cap, the flange abuts on the upper end of the restraining part to prevent the restraining part from being released from the bite.

According to the present invention, since the overcap has a flange that abuts on the upper end of the restraining part and prevents the restraining part from being released from the bite, the pouring cap can be easily injected even if there is vibration such as transportation. It will not come off the container and will not leak. However, if the overcap is removed, the restraining parts can be released from the bite, so that the dispensing cap can be removed and the opening can be widened, so that the dispensing container can be refilled very easily.

Hereinafter, an example of an embodiment of the pouring container of the present invention will be described with reference to the drawings.
The pouring container 1 of FIG. 1 is composed of a container main body 2, an overcap 3, a pouring cap 4, and a restraining part 5.

As the container body 2, a blow bottle having a capacity that is easy to hold and easy to pour out is used. A bottle screw portion 22 is provided on the outside of the opening 21 of the blow bottle so that it can be screwed into the pouring cap 4.
As shown in FIG. 6-3, the container body 2 is provided with a bottle screw portion 22 screwed into the injection cap 4 on the outer surface of the opening 21 and a bite portion 23 at the base of the opening 21.
The occlusal portion 23 bites with the occlusal projection 52 in a state where the restraining part 5 is lowered to prevent rotation. As a result, the rotation of the pouring cap 4 can be stopped, and the pouring cap 4 can be stopped so as not to come off from the container body.

As shown in FIG. 4, the dispensing cap 4 is composed of a dispensing cylinder 41, a peripheral wall 42, an inner bottom 43, an outer cylinder 44, an upper cylinder 45, and an upper plate 46.

The dispensing cylinder 41 has a shape in which the left and right ends of a rectangular sheet having a large upper corner are not aligned and a gap 411 is provided and wound. That is, it has a directional shape in which the center and one end of the circumference are opened so that the contents can be easily poured out in one direction.
The peripheral wall 42 is formed so as to surround the lower periphery of the dispensing cylinder 41.
The lower end of the dispensing cylinder 41 and the lower end of the peripheral wall 42 are connected by an inner bottom 43, and the inner bottom 43 is inclined with respect to a plane perpendicular to the dispensing direction, and the opening is provided in the vicinity of the inclined lower end. A storage port 431 that connects to the gap 411 and leads to the inside of the container is formed.

The upper end of the peripheral wall 42 and the upper end of the outer cylinder 44 are connected by an upper plate 46.
An upper cylinder 45 having an upper screw portion 451 to be screwed into the overcap is provided on the upper portion of the upper plate 46.
Further, an outer cylinder screw portion 442 screwed into the bottle screw portion 22 of the container body is provided on the inside of the outer cylinder 44, and a locking projection 441 for locking to the restraining part 5 is provided on the outside of the outer cylinder 44.
As shown in FIGS. 4-1 and 4-2, it is preferable that the locking projection 441 has a downward slope so that it can be easily inserted when the restraining part 5 is fitted.

As shown in FIG. 5, the overcap 3 includes a measuring unit 31 that looks like an inverted cup, a measuring top plate 32 that extends horizontally from the outer surface of the measuring unit 31, and an outer wall 33 that hangs down from the periphery of the measuring top plate 32. And is composed of.
The outer wall 33 is provided with a female screw 331 that is screwed into the upper screw portion 451.
Further, as shown in the assembled cross-sectional view of FIG. 1, the tip of the measuring portion has a diameter and length sufficiently larger than that of the dispensing cylinder 41, and has a diameter smaller than that of the upper cylinder 45 and the peripheral wall 42. It can be inserted into those gaps. Therefore, when the overcap 3 is closed, the overcap 3 is screwed into the dispensing cap 4 to cover and protect the dispensing cylinder 41.
Further, when it is removed, a linear measuring wire 311 provided on the inner circumference at the same height is provided on the inner surface of the measuring unit 31 so that it can serve as a measuring cup.
In particular, the lower end of the outer wall 33 has a flange 332 that extends outward, and when the overcap 3 is fitted in the dispensing container, the head of the restraining part 5 is pressed to ensure that the dispensing cap 4 opens at the opening 21. It is possible to stop it so that it does not come off.

As shown in FIGS. 6-1 and 6-2, the restraint part 5 has a part body 51 formed of a cylindrical body, and is inserted on the inside of the lower end of the part body with a bite protrusion 52 and on the circumference of the body. A plurality of fitting portions 511 are provided.
Further, as shown in FIG. 1, the length of the part main body 51 is adjusted to the height of the upper end of the upper plate 46 of the pouring cap 4 when the lower end abuts on the upper end of the opening 21 of the container main body 2.
The insertion portion 511 is formed of a vertically elongated hole or a vertically elongated recess, and is loosely fitted into the locking projection 441 of the dispensing cap 4 to rotate in accordance with the movement in the rotation direction with the dispensing cap 4. It is possible to move and stand still.
By setting in this way, when the overcap 3 is fitted in the dispensing container, the head of the restraining part 5 is pressed to ensure that the dispensing cap 4 does not come off from the opening 21.

The refilling process of the dispensing container 1 including the container body 2, the overcap 3, the dispensing cap 4, and the restraining part 5 will be described with reference to the process diagrams of FIGS. 2 to 3.
FIG. 2-1 is a step of rotating the overcap 3 and removing it from the pouring cap 4.
Since the overcap 3 and the injection cap 4 were closed by the screwing of the female screw 331 and the upper screw portion 451, the overcap 3 is rotated to loosen the female screw 331.
When the female screw 331 of the overcap 3 is loosened, the flange 332 of the overcap 3 rises from the position where the upper end of the restraining part 5 is held down, and the raised height allows the restraining part 5 to slide up and down. Become.

FIG. 2-2 is a step in which the overcap 3 is rotated to completely remove the female screw 331 from the upper screw portion 451 of the upper cylinder 45, and the overcap 3 is completely removed from the pouring cap 4.
When the overcap 3 comes off from the pouring cap 4, the flange 332 of the overcap 3 that holds the upper end of the restraint part 5 also comes off, so that the restraint part 5 has only the gap between the height of the insertion portion 511 and the locking projection 441. , Can be moved upward.
When the restraint part 5 moves upward and the bite protrusion 52 of the restraint part 5 comes off from the bite portion 23 at the base of the opening 21, the injection cap 4 can rotate.

In FIG. 3-1 the dispensing cap 4 can be rotated by moving the restraining part 5 upward and removing the biting protrusion 52 of the restraining part 5 from the biting portion 23 at the base of the opening 21. This is a step of removing the pouring cap 4 from the opening 21.
The occlusal protrusion 52 is disengaged from the occlusal portion 23, and the injection cap 4 is rotatable with respect to the container body 2.
However, even at this time, the insertion portion 511 of the restraining part 5 is inserted into the locking projection 441 of the dispensing cap 4 to restrain the rotation.
Therefore, the restraining part 5 and the dispensing cap 4 do not rotate relatively, but rotate together with respect to the container body 2 in a state of being fitted and assembled with each other.
That is, by rotating the restraining part 5 while maintaining the state of being moved upward, the dispensing cap 4 is rotated, and the outer cylinder screw portion 442 screwed to the bottle screw portion 22 is loosened and removed. As a result, the pouring cap 4 is removed from the container body 2.

FIG. 3-2 is a diagram showing a process of removing the restraining part 5 and the pouring cap 4 from the container body 2 and filling the contents 7 from the refill pack 6.
In this way, if the restraining part 5 and the dispensing cap 4 are completely removed from the container body 2, the opening 21 is not obstructed and can be opened wide. Therefore, even if the position of the refill pack is slightly displaced, there is a problem. Refilling is possible without refilling.
Even if the opened portion of the refill pack 6 is not opened cleanly, the tip can be inserted deeply, so that the contents 7 can be refilled without leaking.

The container body used in the present invention is not particularly limited as long as it does not swell or deteriorate due to the contents and can be fused with the lid material.
A highly rigid container is preferable because it is easy to hold and stand upright.
Further, it is preferable that the whole or a part of the container is made of a visible material so that the remaining amount can be known. If the contents of the refill container can be seen visually, the state of filling of the contents can be known, so it is easy to judge whether the refill has been completed, and by mistake, before the refill is completed. There is no risk of pulling out the refill container from the dispensing cylinder and contaminating it with the contents.
Specifically, as the molding material of the container body, in addition to glass, high-density polyethylene, polypropylene, acrylonitrile, polymethylpentene, cyclic polyolefin, polycarbonate, polyethylene terephthalate, polyamide, polyether sulfone, and the like can be considered.
Of course, it may be a direct blow molded product, but a biaxially stretched blow molded product is more preferable in terms of transparency, rigidity, and light weight.

The injection cap, overcap, and restraint part can be easily made by injection molding or compressibility using a thermoplastic resin or thermosetting resin that does not swell or deteriorate depending on the contents.
Specific materials used include polypropylene, high-density polyethylene, medium-density polyethylene, ethylene / propylene copolymer, acrylonitrile, polymethylpentene, cyclic polyolefin, polycarbonate, polyamide, acrylonitrile / butadiene / styrene copolymer, acrylonitrile / A styrene copolymer, etc. can be used.
However, as the material of the injection cap, it is preferable to use a resin different from the resin used for the container body and the overcap that rub against each other.

The pouring container of the present invention is as described above, and the pouring cap does not loosen and leak even if there is vibration during transportation. Moreover, by removing the overcap, the restraint parts can be released from the bite, and the injection cap can be completely removed from the container body. For this reason, when refilling, the opening can be opened wide, and the spout of the refill pack can be reliably inserted into the opening, so the surroundings are not easily soiled with the contents, and refilling can be done quickly. It is a container.
