Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a container made of a soft packaging material in which a soft packaging material such as a resin film or paper is formed in a sealed container shape and mainly for storing contents, and particularly to a container such as a plastic bottle (a container used repeatedly). The present invention relates to a refill container for storing refill contents for filling.
[0002]
[Prior art]
Generally, there is a so-called pouch container which is formed in a sealed container shape by bonding a soft wrapping material such as a resin film or paper and which can be opened by tearing a corner of the container. Such a pouch container is used mainly as a container for liquid products such as foods, beverages, detergents, and cosmetics because it is lightweight, has excellent flexibility and durability, is easy to process, and can be manufactured at low cost.
In particular, in recent years, containers made of a soft packaging material have been widely used as refill containers for storing refill contents to be filled into reusable containers such as plastic bottles.
[0003]
By providing the contents for refilling by filling them in a pouch container, the main container such as a plastic bottle can be used repeatedly, and the pouch container for refilling can be folded small after use and discarded. Since it can be used, it is helpful to solve the problem of waste of resources, the amount of garbage disposal, and the burden of disposal work.
For this reason, refill containers made of a soft wrapping material have rapidly spread in recent years.
Here, the operation of refilling the contents stored in the refill container made of such a soft packaging material is performed as follows. First, a corner or the like of a refill container in which contents for refilling are sealed is torn by hand or cut with scissors or the like to form a spout. Next, the spout of the refill container is aligned with the opening on the side of the reusable container to be refilled, and in this state, the refill container is tilted and the contents are repeatedly poured into the use container. When all contents have been relocated, discard the refill container.
[0004]
However, in the conventional refill container, since the container is formed of a soft packaging material having high flexibility and flexibility, the container is easily deformed during the refilling operation, and is likely to be in an extremely unstable state. was there.
For this reason, in the conventional refill container, the work of repeatedly transferring the contents to the used container side repeatedly without spilling or overflowing the surroundings, etc., is careful of the inclination angle of the refill container while aligning the mouth of the container and the mouth. However, it has to be carried out with care and time, and even in such a case, it has been difficult to completely eliminate liquid spillage.
In addition, since refilling of high-viscosity contents such as detergents takes time, during that time, it is necessary to maintain concentration and the like. Naturally, leaving the place or performing other work etc. I couldn't do anything like that.
[0005]
For this reason, it is an exaggeration to say that it is extremely difficult for a conventional refill container to complete a refill operation without failure, especially for those who are not very dexterous or have poor patience, such as the elderly and children. Did not.
In addition, even for a housewife or the like who is accustomed to it, refilling work that is restricted for a certain period of time during busy housework and the like is extremely complicated.
As described above, in the conventional refilling container, the attention, concentration, and skill of the worker are required for the refilling operation, and moreover, a certain period of time until the refilling is completed must be carried out in a regular manner, and the patience and sustainability are required. Because of the necessity, refilling was a heavy burden, both mentally and physically. For this reason, there has been a strong demand for the development of a new container that can be easily and reliably refilled by anyone and that can effectively use the working time.
Therefore, in order to solve such a difficulty of the conventional refilling operation of the refillable container, a technique has been proposed which eliminates the refilling operation itself by storing the refillable container in the used container repeatedly as it is. (For example, refer to Patent Documents 1-4).

[Problems to be solved by the invention]
However, if the refillable container has a structure that can be repeatedly stored in the used container, the size of the repeatedly used container will be correspondingly increased, and an opening / closing structure, a holding structure, and an opening portion that can store the refillable container in the repeatedly used container will be provided. The structure of both the reusable container and the refill container, such as the connection structure, becomes complicated, and the problem that the production cost of the container increases.
Further, in such a container, since both the repeatedly used container and the refillable container require a special storage structure corresponding to each other in shape and size, there is no versatility or expandability as a container, and generally, There was also a problem that it could not be applied to ordinary containers that are widely used.
[0008]
In addition, the present applicant has already disclosed in Japanese Patent Application Laid-Open No. 9-193954 an invention of a “container coupler assembly” in which the work load of a refill container is eliminated and anyone can easily and accurately perform the refill operation. is suggesting. According to the present invention, since the reusable container and the refilling opening are connected by the tubular spout member, there is no danger of the contents being spilled during the refilling, and attention, concentration, individual skill and the like are required. It became possible to perform refilling work easily without having to do so.
However, also in the present invention, a special cap having a tubular spout member needs to be prepared, and there is room for improvement.
[0009]
The present invention has been proposed in order to solve such problems of the conventional technology, by providing a refill container with a coupling member that fits into the opening of the reusable container to be refilled, By simply providing a simple, small, and lightweight configuration on the refill container side, there is no need to carefully maintain the refill container or the container used repeatedly, and anyone can easily and reliably refill the contents. The purpose is to provide refillable containers.
In particular, the present invention provides an unprecedented superior refillable unreserved container that allows refilling to be easily and reliably performed without reserving, eliminating the need for monitoring during refilling and enabling other operations during refilling. Aim.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, a refillable container according to claim 1 of the present invention is a refillable container for storing refillable contents to be filled in a repeatedly used container having an opening on one side, and a refillable container main body. And a coupling member detachably and irremovably connected to the opening of the repeatedly used container, and a container sealing member for sealing the refillable container main body.
Particularly, in the second aspect, the coupling member is formed of an annular member provided at an opening of the refill container main body.
[0011]
According to the freely refillable container of the present invention having such a configuration, by providing the annular connecting member at the opening on the refilling container side, the connecting member is fitted to the periphery of the opening of the repeatedly used container to be refilled. The refill container can be repeatedly attached to the use container so as not to fall off, and the openings of both containers can be connected.
The two containers connected in this way can be repeatedly used from the refill container without the stored contents being spilled around the opening or the like by screwing or fitting the opening edges so that they cannot fall off. Can be transferred to
Therefore, for example, by connecting and fitting the coupling member to the upper opening of the repeatedly used container installed in the upright state, the refill container can be repeatedly attached to the used container in the inverted state, and the contents in the refill container can be attached. Can be automatically and repeatedly transferred to the use container side.
[0012]
Moreover, since the refillable container is repeatedly attached to the used container side so as not to fall off via the coupling member, there is no need to hold the container being refilled by hand or adjust the angle at all. That is, according to the present invention, the refilling operation is automatically performed without giving up, and it is not necessary to monitor the refilling, and as a result, it is possible to leave the place or perform another operation.
As described above, according to the present invention, only the provision of the annular coupling member at the opening of the refill container allows anyone to perform the refill operation extremely easily and reliably.
Moreover, since the annular connecting member has only an extremely simple configuration, it can be attached to any refill container, and can be mounted and fitted to any reusable container simply by changing the diameter of the connecting member. It is possible to make the refill container excellent in versatility and expandability.
[0013]
In addition, in the hand-held refill container according to claim 3, the reusable container is provided with an outflow nozzle protruding from an opening, and a coupling member of the refill container is attached to the opening of the reusable container. Thereby, the container sealing member is cut by the nozzle, and the refill container main body is opened.
[0014]
According to the hand-held refill container of the present invention having such a configuration, even when a nozzle for outflow of contents is provided on the side of the repeatedly used container, the nozzle can be inserted through the annular coupling member. While the container sealing member is cut and opened by the nozzle, the refill container can be repeatedly and irremovably connected to the container to be used.
Recently, a reusable container containing contents such as laundry detergent has been provided with an opening called a transition cap, which is provided with a nozzle for liquid outflow. A reusable container equipped with such a transition cap can discharge the contents in a desired direction via a nozzle in a desired amount, thereby facilitating the outflow work, but also allows the liquid for refilling from a tubular nozzle to be refilled. There is a problem that the work of refilling is extremely complicated.
In the present invention, since the tubular nozzle provided in such a transition cap is inserted into the refill container through the annular connecting member, the refilling operation is automatically performed without giving a hand. Thus, the present invention can be applied to a reusable container having a transition cap provided with a tubular nozzle protruding therefrom, and a refill container excellent in versatility, capable of performing easy and reliable refilling work. be able to.

In addition, the refill container can be automatically opened and refilling can be started simultaneously with the repeated use of the container.
Thus, before the refilling operation is started, the contents such as the liquid do not spill at all, and the refilling operation can be performed more easily and surely.
[0017]
And especially in Claim 5, it is set as the structure which consists of an easy-cut lid which is broken and opened by being pressed by the nozzle.
[0018]
According to the freely refillable container of the present invention having such a configuration, the inner lid structure automatically opened by the nozzle of the repeatedly used container side, particularly the easy-cut lid structure that is easily broken by the nozzle. it can.
By adopting the inner lid having the easy-cut lid structure as described above, a container that can be easily opened at low cost can be manufactured.

According to a sixth aspect of the present invention, there is provided a configuration including an outer lid that covers the outside of the coupling member.
In particular, in claim 7, the outer lid is made of an adhesive material.
[0020]
According to the hand-held refill container of the present invention having such a configuration, by including the outer lid that covers the outside of the coupling member, the outer side of the inner lid of the refill container before opening can be further covered with the outer lid, It is possible to prevent foreign matters such as dust and dust from adhering and mixing into the inner lid portion.
Further, by providing such an outer lid, after the refilling operation is completed, the outer lid can be used to cover the outer side of the inner lid again, and the remaining liquid in the refill container can be prevented from falling out. Further, the refilled container can be held in a folded state by using the outer lid, and it is possible to prevent the folded container from being restored to a three-dimensional shape for disposal or the like, and to maintain a reduced volume state. it can.
In particular, by forming the outer lid with an adhesive material constituting an adhesive cover or the like, the outer lid can be repeatedly opened and closed and adhered, and the outer lid can be opened and closed before opening, after opening, and before and after refilling work. Since it can be stuck to a container, a more convenient refillable container can be obtained.
[0021]
In the hand-held refill container according to claim 8, the refill container main body is a pouch container made of a soft wrapping material.
Particularly, in the ninth aspect, the refill container main body is configured to be a shrink container made of a heat-shrinkable film.
[0022]
According to the freely refillable container of the present invention having such a configuration, the main body of the refillable container can be a pouch container made of a soft packaging material made of a resin film or a paper sheet material. And a shrink container using a heat-shrinkable film.
The pouch container is a container structure that is most popular as a refill container for contents.
On the other hand, a shrink container is a new container proposed by the present applicant in Japanese Patent Application No. 2002-192659, and is a container formed by using a resin film that thermally shrinks at a constant shrinkage rate, and is easy to mold. It is thin and lightweight, yet has high rigidity and can be easily recycled, and is suitable for refill containers. In the present invention, such a shrink container can be used as a refill container.
As described above, the present invention can be implemented by selectively employing any material suitable for a refill container.
[0023]
Further, the refillable container according to claim 10 has a structure in which one or two or more anti-bending ribs are formed on the side surface of the refillable container main body along the outflow direction of the contents to be filled in the repeatedly used container. .
[0024]
According to the freely refillable container of the present invention having such a configuration, by forming, for example, a protruding rib on the side surface of the refillable container main body made of a soft packaging material such as a resin film, in the direction in which the contents flow out. Along with this, the rigidity of the refill container can be increased.
As a result, the shape of the refill container can be improved to prevent breakage and bending, and even during the refill operation, the shape of the refill container can be kept straight along the outflow direction of the contents. Can be performed.
