[Technical field to which the invention belongs]
[0003]
The present invention relates to a liquid storage container provided with an inlet for injecting the liquid from a refill container filled with a liquid such as a liquid detergent, and a refilling cap placed on the inlet.
[0004]
[Prior art]
From the viewpoint of protecting the natural environment through resource saving and waste reduction, it is possible to repeatedly use a liquid storage container (hereinafter, appropriately referred to as a bottle) for storing a liquid such as a liquid detergent. In recent years, refill liquids for the above-mentioned liquids, which are the contents of bottles, have been marketed over many types.
FIG. 4 shows a schematic view of a general refill container for storing the refill liquid. The refill container is crimped on the peripheral edge of two film-like materials made of polyester or aluminum foil so that the volume can be reduced after the contents (liquid for refill) are refilled into bottles. Alternatively, a bag-like container made by bonding by a melting process or the like is used. That is, FIG.
As shown in FIG. 0000), the refill container is composed of a paste margin portion 51 which is a so-called paste margin bonded together as a peripheral portion of the film, and a space appearing by bonding, that is, a refill liquid storage portion 52. Become. In the state of being distributed, all the mouths of the refill container are bonded together by a crimping process or the like so that the contents do not spill outside.
[0005]
The worker who performs the refilling work cuts off one end (for example, the dotted line portion L in FIG. 4) of the refilling container with a scissors or the like, and a pouring hole that leads to the paste margin 51 as shown in FIG. 53 is formed, and refilling is performed by transferring the contents from the spout through the bottle inlet (usually a spout from the bottle) into the bottle container.
At this time, if the spout of the refill container and the inlet of the bottle are displaced, the refill liquid spills outside the bottle. Therefore, the operator needs to pay close attention during the refilling operation so that the spout of the refill container and the injection port of the bottle do not shift. In particular, since the refill container uses a bag made of a film-like material as described above, if the contents are reduced due to refilling work, the shape of the container will be deformed accordingly. There has been a problem that the position where the pouring spout and the pouring spout are adjusted in accordance with the change must be finely adjusted, and the work is complicated.

DETAILED DESCRIPTION OF THE INVENTION
Next, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows an overall view of a liquid storage container 100 according to an embodiment of the present invention.
1 (a) is a perspective view, and FIG. 1 (b) shows the body 1 of the liquid storage container 100 in FIG. 1 (a) in the direction a (the direction normal to the injection surface including the injection port). It is the top view seen from.
The liquid storage container 100 according to the present invention includes a body 1 for storing a liquid such as a liquid detergent as a content, and a lid 2 that is detachable from the body 1.
[0011]
The body 1 is a so-called bottle-like container partially provided with a mouth, and a storage unit 3 having a volume capable of storing a predetermined amount (for example, 500 ml) of the liquid, and a refill for the storage unit 3. It consists of an injection port 4 for injecting a refilling liquid from the container and pouring the injected liquid to the outside as necessary.
The lid 2 includes a nozzle hole 21 for injecting the liquid stored in the body 1 supplied via the injection port 4 to the outside, and a liquid storage container by closing the nozzle hole 21 when the nozzle hole 21 is not used. 100, for example, several grooves are formed on the side surface of the convex portion including the injection port 4 in the body 1, and on the other hand, a groove in which the groove just fits is formed on the inner surface of the lid 2. With the structure that can be screwed to each other, the body 1 is detachable.
[0012]
Next, the inlet 4 will be described.
The injection port 4 has a pair of cutting holes as a holding portion that holds a pouring hole of a refilling container at a position substantially symmetrical with respect to the center O of the injection hole 41 and a predetermined shape, for example, a circular injection hole 41. It consists of a notch 42 and 42. The diameter R2 of the injection hole 41 is larger than the diameter D2 of the pouring hole 53 of the refill container shown in FIG. Further, the width R3 of the notch 4242 is larger than the thickness D3 of the paste margin 51 of the refill container. Furthermore, the maximum diameter R1 of the inlet 4 is larger than the maximum diameter D1 of the spout.
[0013]
From the above configuration, the spout of the refill container shown in FIG. 3 can be inserted into the injection port 4. The margin portion 51 of the refill container is the portion having the highest rigidity in the refill container because at least two films are bonded together by a crimping process or the like. Since such a highly rigid portion is sandwiched between the notches 4242, the spout of the refill container can be stably held.
[0014]
Therefore, once inserted, the spout of the refill container and the bottle inlet are not easily displaced, and the possibility that the contents may spill outside is reduced even if the operator does not pay special attention. it can.
If the refill cap shown in FIG. 2 is used, the present invention can be applied to a conventional bottle (a bottle having only an injection hole as an injection port).
[0015]
The cap 200 for refill shown in FIG. 2 was conceived on the assumption that it would be used over a conventional bottle inlet when refilling, and the normal of the injection surface including the conventional bottle inlet. A predetermined shape having a diameter slightly larger than the diameter of the inlet when viewed from the direction, for example, a circular shape, and a shape perpendicular to the normal direction, that is, a shape viewed from the side of the cap is a convex shape 1 and has the same structure as the injection port 4 shown in FIG. 1 on the flat surface of the pedestal (the surface parallel to the injection surface of the bottle when the bottle is covered), that is, the injection hole 41 and the injection hole. A pair of cutouts 42 42 are provided as holding parts for holding the spouts of the refilling containers at substantially symmetrical positions with respect to the center O of 41.
[0016]
By covering the refill cap 200 over the conventional bottle inlet, the liquid storage container 100 of the present invention shown in FIG. 1 can be made substantially the same structure, so that the conventional bottle is used as it is. Can also enjoy the effects of the present invention, and is particularly preferable from the viewpoint of protecting the natural environment.
[0016]
In the above-described embodiment, an example in which the pair of notches 42 and 42 is used as the holding portion has been described. However, the present invention is not limited to such an example, and instead of the notches, for example, as shown in FIG. Two convex portions 42'42 ', which are a set of two sheets arranged so as to have a slightly larger gap with respect to the thickness D3 of the adhesive margin 51 of the container, are arranged at two positions symmetrical to the injection hole. You may make it the structure to carry out. In short, any configuration may be used as long as the paste margin 51 of the refilling container is held and the pouring spout of the refilling container and the injection port 4 of the liquid storage container are not easily displaced.
[0017]
Moreover, although the said embodiment demonstrated the bag-shaped container which bonded two film-like materials together as an example as a refill container, it is applicable also to the refill container which made the film material of one sheet into a bag shape. At this time, the holding portion (notch) of the spout of the refilling container may be only one place.
【The invention's effect】
As described above, according to the liquid storage container and the refill cap of the present invention, the injection hole formed in a predetermined shape such as a circle or a rectangle into which the liquid transferred from the refill container is injected, and the refill container Since the holding portion for holding the spout is provided, it is possible to hold a state in which the spout formed by cutting one end of the bag-like refill container is aligned with the inlet of the bottle. Therefore, it is possible to reduce the complexity of combining the spout of the refill container and the bottle inlet generated during the refilling operation.
