Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a liquid ejecting apparatus adopting a liquid refilling method.

[0002]

[Prior art]

 Many liquid ejecting apparatuses have been proposed in the past and are very well known. Japanese Utility Model Laid-Open No. 2-81653 is one of those examples. As can be seen from this publication, the liquid injection device is a pump-type injector main body attached to the mouth and neck of the container containing the liquid with a screw cap. It is a thing.

That is, a push-down head with a nozzle tube is connected and fixed to the upper end of the system which is erected upward from the vertical cylinder provided inside the mouth and neck of the container body, and the push-down head is resisted against returning. By pushing down, the cylindrical piston at the lower end of the stem pressurizes the liquid in the cylinder, and this liquid itself is injected from the nozzle pipe to the outside by opening the discharge valve in the upper part of the stem.

When the liquid injection ends, the movable parts of the cylindrical piston, the stem, and the push-down head return upward by the return spring, and the negative pressure inside the cylinder is caused by this return. The suction valve is opened to suck the liquid from the container into the cylinder and prepare for the next injection.

[0005] In this type of device, there is an example in which a refilling method, that is, a method of separately preparing a container body containing a storage liquid, is adopted so that the running cost borne by the consumer is low. .

[0006]

[Problems to be solved by the device]

 As described above, the refillable container body of this type of injection device is the same as the container body of the injection device with the cap, and in other words, it continues without changing only the pump type injector body. This is the method used, and the cost merit is insufficient.

Although a refill bag in which a refill solution is stored in a simple bag has been provided for a long time, in this case, the refill bag is simply stored, and the refill bag serves as a container body. It has no function.

An object of the present invention is to provide a liquid injection device in which a refillable container body is incorporated in a reinforcing case as a simple and inexpensive bag body structure and the running cost can be further reduced.

[0009]

[Means for Solving the Problems]

 The liquid ejecting apparatus of the present invention is a self-supporting type having an oval-shaped body portion 1, and a top plate 3 having an opening 2 in the center is extended from both upper ends of the body portion 1 by folding inward unit top plates 3a, 3b. In a reinforcing case 4 formed by stacking, a refillable container body 8 with a cap 7 in which a rigid mouth / neck portion 6 is erected from the upper end of the bag-shaped body portion 5 is held, and the mouth / neck portion 6 is held by the top plate 3. Moreover, the injector body 10 is housed by projecting upward from the opening 2, and the refillable container body 8 is fitted with the injector body 10 via the mouth / neck portion 6 by the screw cap 9.

[0010]

[Action]

 In the above, the reinforcing case 4 and the injector main body 10 are continuously used, and the refillable container body 8 is an optional one and is replaced every time the liquid is refilled.

When refilling the liquid, the cap 7 of the container body 8 is removed, and the container body 8 is placed in the reinforcing case 4 having the shape as shown in FIG. 1, that is, the unit top plates 3a and 3b at the upper end of the reinforcing case 4 are moved upward. First, the body 5 is stored with the two standing upright and open on both sides, and then the unit top plates 3a and 3b are folded inwardly to form an opening 2 in the center, and at this time, the mouth 2 is surrounded by the mouth and neck 6. The injector body 10 is attached to the container body 8 by holding the lower portion and projecting the mouth / neck portion 6 to the upper outside, and then screwing the screw cap 9 on the mouth / neck portion 6.

[0012]

【Example】

 An embodiment will be described below with reference to the drawings. In the present invention, a refillable container body 8 is combined with a reinforcing case 4 as a simple and inexpensive bag body structure so that the running cost can be further reduced. It has a feature in the point.

The body part 5 of the refillable container body 8 is a flexible one formed of a bag made of a synthetic resin such as vinyl, and for example, a long sleeve-like body pre-clamped is suitable. Cut into lengths, and glue one opening in a letter shape to form the bottom, and glue the two edges to the other opening to form a round mouth in the center, which is made of a synthetic resin made separately. The lower part of the mouth / neck portion 6 is integrally fitted and bonded. At the lower part of the portion projecting above the mouth / neck portion 6, flanges 11 and 11 facing each other vertically are formed at appropriate intervals. 7 is a cap.

The reinforcing case 4 is a flat, but self-sustaining, container-shaped body having a body portion 1 having an oval cross section, and a top plate 3 at the upper end is thin from both upper ends in the longitudinal direction of the body portion 1. The unit top plates 3a, 3b extended via the hinges 12, 12 are folded inward, and in this case, they are formed by stacking the first half of these.

At the center of each of the unit top plates 3a, 3b, a slightly longer groove 2a, 2b with a semi-circular end is cut out, and both unit top plates 3a, 3b are folded to form a single top plate 3. The grooves 2a and 2b which are overlapped with each other at different times form one perfect circular opening 2. The reinforcing case 4 is formed by molding a synthetic resin material with rigidity, but in some cases, it is conceivable that the reinforcing case 4 is formed of waterproof cardboard.

The injector body 10 is a well-known pump type, and since it is not directly related to the gist of the present invention, a brief description will be given. In FIG. 13, reference numeral 13 is a vertical type in which a suction valve is installed in the bottom opening. The cylinder, 14 has its lower end communicated and fixed to the cylindrical piston in the cylinder 13, and is pushed upward by the return spring in the cylinder 13 to the outside, and the stem with the discharge valve installed in the upper part, 15 is the upper end of this stem 14. The pressing head, 16 is a nozzle tube, and 17 is a suction pipe, which is attached to the refillable container body 8 via the mouth / neck portion 6 by a screw cap 9.

The liquid ejecting action is the same as that described in the section of the prior art, and the description thereof is omitted because it overlaps.

Further, in the drawings other than FIG. 1, the push-down head 15 is at the lower limit position, but in order to prevent an inadvertent push-down operation during distribution, the screw on the lower surface side of the push-down head 15 is attached to the screw cap 9. This is because the state is shown in which the top plate is screwed into the peripheral edge of the opening.

In this embodiment, when refilling the liquid, the container case 8 with the cap 7 removed with the reinforcing case 4 standing upright on both unit top plates 3a and 3b as shown in FIG. Then, both unit top plates 3a and 3b are folded inward and stacked, and in this case, the grooves 2a and 2b of the unit top plates 3a and 3b are inserted from both sides between the collars 11 and 11 below the mouth and neck 6. The mouth / neck portion 6 is held so that the mouth / neck portion 6 is inserted through the opening 2 from these, and then the screw cap 9 is screwed onto the mouth / neck portion 6 to attach the injector main body 10 to the container body 8.

In the above description, the liquid ejecting device is simply described, but the present invention not only ejects the liquid in the form of a water column, but also a sprayer for ejecting the liquid in a mist state, and a creamy substance ejector for ejecting the creamy substance. It goes without saying that it can be widely applied to the above.

[0021]

[Effect of device]

 As described above, in the liquid ejecting apparatus of the present invention, the refillable container body 8 is made of a synthetic resin bag so as to be simple and inexpensive, so that the running cost can be further reduced.
