Description

  The present invention relates to a refill container suitable for storing household detergents such as kitchen detergents, toilet detergents, liquid detergents such as shampoos, and liquid foods such as edible oil, soy sauce, sauce, and vinegar, and liquid glue.

  A container for liquid detergent generally used at home or the like is a plastic bottle-like container having a certain degree of rigidity. In order to hold the container by hand and stably pour the detergent inside the container into the washing tub of the washing machine, the container needs to have a certain degree of rigidity. In order to give the plastic bottle-shaped container certain rigidity, the plastic plate-like wall member in the container needs to have a thickness of about 0.5 to 1 mm. Therefore, it is required to keep the plastic weight per volume of the container above a certain value. When the liquid detergent is circulated from the manufacturer to the home in such a plastic bottle-like container having a certain degree of rigidity, the container is discarded every time the container is consumed. The large waste weight of plastic bottle-shaped containers means a large environmental burden and economic burden in waste disposal.

  Therefore, until the product is delivered from the manufacturer of the liquid detergent to the home, a refill bag for the liquid detergent is used as a distribution means. The refill bag is made of a thin sheet of flexible plastic. Since the weight per volume of the refill bag is a fraction of that of the bottle-shaped container, the environmental load and the economic burden in the disposal of the refill bag are a fraction of that of the bottle-shaped container. It is.

  The corner of the refill bag is devised so that a liquid detergent outlet is formed by cutting with a scissors or the like. However, since the refill bag is a thin sheet and is highly flexible, the liquid detergent can be used even if considerable care is taken when pouring the liquid detergent from the outlet to the inlet of the bottle-like container. Often, a leak occurs outside the bottle-like container's inlet, causing troubles to refill liquid detergents (such as housewives at home).

Therefore, in order to facilitate such refilling work, a container described in Patent Document 1 has been proposed. The container described in Patent Document 1 is formed by attaching a collar (3) to the lower part of a container body (2). The funnel-shaped part (10) is provided in the collar part (3). When refilling the liquid detergent, remove the flange (3) from the lower part of the container body (2), and insert the insertion part (11) of the funnel-shaped part (10) into the upper part of the container body (2) ( 7) Insert the liquid detergent into the funnel-shaped part (10) from the outlet of the refill bag.
JP 07-101477 A

  The container described in Patent Document 1 is provided with a flange (3) separately from the container body (2). In this structure, since the flange part (3) used only at the time of refilling contains the funnel-like part (10), it is a considerable size. When the liquid detergent is poured from the container body (2) into the washing tub of the washing machine, the reed container (3) is fixed to the lower part of the container body (2), so the refill container is bulky and the refill container is easy to use. Is bad. In addition, the flange (3) in the container described in Patent Document 1 has the same size as the lower part of the container body (2). Since such a considerably large collar part (3) is structured to be attached to and detached from the container body (2), the structure of the container body (2) and the collar part (3) is complicated. Manufacturing costs are expensive.

  Accordingly, an object of the present invention is to provide a refill container that is easy to use and can be manufactured at low cost.

In order to solve the above-described problems, the present invention provides the following means.

  (1) having a funnel-shaped portion with the bottom surface raised in a funnel shape, an inlet port provided in the most recessed area of the funnel-shaped portion, and a lid member serving as a lid for the inlet port portion Characteristic refill container.

  (2) A female screw is formed in the injection port, and the lid member is a male screw with a screw head screwed to the female screw, and a cross groove or a minus groove is formed in the screw head. The refill container according to (1) above, wherein

  According to the present invention having the above-described configuration, a refill container that is convenient and inexpensive to manufacture can be provided.

  Next, embodiments of the present invention will be described with reference to the drawings. 1A and 1B are diagrams showing an embodiment of the present invention, in which FIG. 1A is a front view and FIG. 1B is a bottom view. 2 and 3 are sectional views of the bottom in the embodiment of FIG. 1, FIG. 2 shows a state in which the injection port 2 is closed with a cover 3 with a male thread, and FIG. 3 shows the cover 3 with a male thread. The state which removed from the inlet part 2 and opened the inlet part 2 is shown. FIG. 4 is a side view (A) and a front view (B) of the lid 3 with the external thread shown in FIGS. 2 and 3.

  In the figure, 1 is a funnel-shaped part, 2 is an injection port part, 2a is a female screw part, 3 is a cover with a male screw, 3a is a cross groove, 3b is a male screw, 4 is a nozzle, 5 is a lever, and 10 is made of plastic. Refillable container (this embodiment), 10a is a seat surface portion.

  The refill container 10 is a container for liquid detergent, and includes a nozzle 4 and a lever 5. By pulling the lever 5, the pump in the refill container 10 pumps the liquid detergent to the nozzle 4, and the mist liquid detergent is ejected from the nozzle 4. In the refill container 10, the nozzle 4 is directed to a particularly dirty part, the liquid detergent is sprayed on the part, the liquid detergent is brought into contact with the dirt at a high concentration, and the dirt is effectively removed, This is effective when spraying detergent uniformly on a wide surface such as a bathroom wall.

  The bottom surface of the refill container 10 is raised in a funnel shape, and the raised bottom surface forms a funnel-shaped portion 1. The central part of the funnel-shaped part 1 is the most recessed area, and the inlet part 2 is provided here. The injection port 2 is formed with a female screw. The male threaded lid 3 (corresponding to the aforementioned lid member) is a male screw with a screw head that is screwed into the female thread of the injection port 2. A cross groove 3a is formed on the screw head. The seating surface of the screw head in the male threaded lid 3 has a conical shape. The conical seating surface is in close contact with the opening edge of the injection port 2 when the male screw 3b of the cap 3 with the male screw is fastened to the female screw of the injection port 2. Is securely closed to prevent the liquid detergent inside the refill container 10 from leaking.

  A method for refilling the liquid detergent contained in a refill bag that is thin and flexible with the refill container of the embodiment of FIG. 1 will be described. First, a 10-yen coin or the like is fitted in the cross groove 3a, the male threaded lid 3 is turned, the male threaded lid 3 is removed from the inlet part 2, and the inlet part 2 is opened (state shown in FIG. 3). The lid 3 is placed on a table (for example, the upper surface of the washing machine), and the refill container 10 with the male threaded lid 3 removed is placed on the table (for example, the upper surface of the washing machine).

  Next, cut off the corners of the refill bag with a scissors or the like to form a liquid detergent outlet, pick up the refill container 10 with the male threaded lid 3 removed from the table, and refill the funnel-shaped part 1 upward. The outlet for the liquid detergent in the bag is positioned on the funnel 1 and the refill bag is tilted. At this time, the liquid detergent flows out from the outlet of the refill bag to the funnel-shaped part 1 and is injected into the refill container 10 through the inlet part 2 at the bottom of the funnel-shaped part 1. When almost all of the liquid detergent in the refill bag is injected into the refill container 10 through the funnel 1, the refill bag is thrown into the trash container, and the male threaded lid 3 on the table is taken in hand. The male screw 3b of the lid 3 with the male screw is screwed into the female screw of the injection port portion 2. At the beginning of this screwing step, the male screw 3b is screwed into the female screw of the injection port 2 by turning the lid 3 with the male screw with a finger. From the middle of the screwing step, 10 yen is inserted into the cross groove 3a. A coin or the like is fitted, the male threaded lid 3 is turned with a 10-yen coin or the like, and the male threaded lid 3 is sufficiently fastened to the female screw of the inlet 2. Thereafter, the funnel-shaped portion 1 is exposed to water (for example, water poured into the washing tub from the water inlet of the washing machine) and washed. Preferably, the moisture on the outer surface of the refill container 10 is then wiped by wiping the entire outer surface of the refill container 10 with a cloth. Through the above steps, the operation of refilling the liquid detergent stored in the refill bag into the refill container of the present embodiment is completed. The refill container 10 filled with the liquid detergent in such a procedure can inject the liquid detergent from the nozzle 4 by directing the funnel-shaped portion 1 downward and pulling the lever 5.

  In the above-described operation of refilling the refill container 10 with the liquid detergent in the refill bag, the liquid detergent stored in the refill bag is poured into the funnel-shaped part 1 at the bottom of the refill container 10. It is injected into the inside of the refill container 10 without leaking. In this refilling operation, the liquid detergent does not leak out of the refill container 10 without requiring much care.

  In the refill container 10 of the present embodiment, the bottom surface also serves as the funnel-shaped part 1, and the funnel-shaped part 1 is integral with the refillable container 10. Therefore, the refill container 10 does not need to be separately provided with a member with the funnel-shaped part 1 [for example, the flange part (3) in Patent Document 1], so that the refill container 10 is larger than a general refill container without the funnel-shaped part 1. As a result, it is easy to use, has a simple structure, and is inexpensive to manufacture.

  FIG. 5 is a diagram showing a male threaded lid 7 as an example of a lid member used in another embodiment of the present invention. 5 has a minus groove 7a in place of the cross groove 3a in the male threaded lid 3 of FIG. Reference numeral 7 b in FIG. 5 indicates a male screw that is screwed into the female screw of the inlet 2. The male threaded lid 7 in FIG. 5 has the same structure as the male threaded lid 3 in FIG. 4 in other points, and as with the male threaded lid 3, a ten-yen coin or the like can be easily fitted into the minus groove 7 a. Can be turned to.

  In the above, the refill container for liquid detergent is mentioned as an embodiment, and the present invention has been specifically described. However, the present invention is not limited to this embodiment. The liquid to be stored may be edible oil, soy sauce, sauce, liquid food such as vinegar, household liquid such as liquid glue, or anything else. Moreover, although the refill container provided with the nozzle 4 and the lever 5 was mentioned in embodiment, what was not provided with such a member, for example, a simple form like the container main body (2) shown by patent document 1 is shown. The present invention can also be applied to those.
