Description

  The present invention relates to a refill container containing a refill fluid to be refilled in a main body container, a refill container spout, and a fluid refill mechanism.

  For example, fluids such as shampoos, rinses, body soaps, and hand gels are stored and sold in main body containers equipped with vertical pumps, trigger pumps, and the like. For such products, discarding the main body container as it is after use is not only uneconomical but also increases the burden on the environment, so a refill container containing a refill fluid is sold separately. Refilling from the container to the main body container is performed.

  Refilling from the refill container to the main body container is performed by pouring the fluid from the outlet of the refill container into the mouth of the main body container, but since the refilling operation is performed by the consumer, the fluid is not refilled at the time of refilling. There is a risk of leakage or scattering to the surroundings. In view of this, conventionally, refill containers having a contrivance in the form of the spout have been proposed (see, for example, Patent Document 1 and Patent Document 2).

  The refill container described in Patent Document 1 is provided with a protrusion for fitting on the outer peripheral surface of the spout, thereby making the outer diameter of the protrusion substantially coincide with the inner diameter of the mouth of the main body container. It is set as the structure which can be fitted to the inner side of the opening | mouth part of a main body container. Further, a groove is provided in the protrusion, and this groove forms an exhaust passage when fitted, so that air in the main body container can be discharged when the fluid is injected.

  The refill container described in Patent Document 2 forms a threaded portion on the outer peripheral surface of the spout and also forms a threaded portion on the inner peripheral surface of the mouth portion of the main body container. It is set as the structure which can fix the spout of a replacement container to the inner side of the opening | mouth part of a main body container. In addition, a flange is provided at the spout of the refill container so that a gap can be formed between the tip of the mouth of the main body container. It can discharge | emit through the clearance gap between the screwing parts by a screw part, and the said exhaust path.

  In the refill container described in Patent Document 1, since the spout of the refill container is only fitted into the mouth of the main body container, the spout and the mouth are not sufficiently fixed. For this reason, for example, when the container falls down during refilling, there is a risk that the fitting may be disengaged and the fluid may leak and scatter around.

  On the other hand, in the refill container described in Patent Document 2, the spout of the refill container can be firmly fixed to the mouth of the main body container by screwing of the screw part. For this reason, there is little possibility that the fitting is disengaged as described above and the fluid leaks and scatters to the surroundings. However, since it is considered that the gap formed in the threaded portion by the screw portion is extremely small, the inside of the main body container is almost sealed. For this reason, the air in the main body container cannot be exhausted when the fluid is injected, and there is a possibility that the refilling cannot be performed smoothly. Further, even if a gap that can be exhausted is formed in the screwed portion, the exhaust path in this case is formed in a spiral shape along the threaded portion, so that the length becomes long. Therefore, the exhaust resistance increases, and in this case, there is a problem that smooth refilling is hindered.

  As described above, none of the above-described conventional technologies can perform smooth refilling while preventing leakage and scattering of the fluid, and it is impossible to achieve both prevention of leakage and scattering and smoothing of refilling. It was.

As a result, the fluid flows through the flow path F of the spout 4 and is poured into the main body container 2 from the opening 44 a of the inner cylinder portion 44. At this time, the air in the main body container 2 is exhausted through the air circulation hole 46 of the outer cylinder portion 43, so that the fluid is smoothly injected into the main body container 2.

In the above description, the case where the refill container 1 is turned upside down and the spout 4 and the mouth portion 21 are fixed has been described as an example. However, the present invention is not limited thereto. Refilling may be performed after fixing the spout 4 and turning the fixed refill container 1 and the main body container 2 upside down to the state shown in FIG.
The refill container 1 and the main body container 2 that are refilled as described above function as a fluid refill mechanism described in the claims. Moreover, the screw part 45 provided in the internal peripheral surface 43c of the outer cylinder part 43 functions as an engaging means as described in a claim.

Next, the effect obtained by this embodiment will be described.
As described above, the spout 4 of the refill container 1 has the outer cylinder portion 43, and the inner peripheral surface 43 c of the outer cylinder portion 43 is provided on the outer peripheral surface 21 a of the mouth portion 21 of the main body container 2. A threaded portion 45 that can be screwed with the threaded portion 22 is provided. By engaging the threaded portion 45 and the threaded portion 22 with each other, the outer cylinder portion 43 is engaged with the outer peripheral surface 21a of the mouth portion 21 of the main body container 2, whereby the spout 4 of the refill container 1 and the main body container 2 are The mouth portion 21 can be firmly fixed. Thereby, the leakage and scattering of the fluid at the time of refilling can be prevented.

  An air circulation hole 46 is formed in the outer cylinder portion 43. The air circulation hole 46 is provided through the bottom 43 b of the outer cylinder portion 43, and the outer cylinder portion 43 engages with the mouth portion 21 of the main body container 2 by screwing of the screw portion 45 and the screw portion 22. When this occurs, the air in the main body container 2 can be circulated. Thereby, the air in the main body container 2 can be smoothly exhausted through the air circulation hole 46 at the time of refilling, and smooth refilling can be performed. As described above, according to the refill container 1 of the present embodiment, smooth refilling can be performed while preventing leakage and scattering of the fluid.

  Further, according to the present embodiment, since the outer cylinder portion 43 of the refill container 1 is engaged with the outer peripheral surface 21a of the mouth portion 21 of the main body container 2 to refill the fluid, the refill is performed for each type of fluid. When trying to refill different types of fluid into the main body container 2 by making the inner diameter d3 of the outer cylinder portion 43 of the replacement container 1 correspond to the outer diameter of the mouth portion 21 of the main body container 1 on a one-to-one basis. Moreover, the outer cylinder part 43 of the refill container 1 can be made unengageable with the mouth part 21 of the main body container 2. Thereby, the refilling of the incorrect fluid can be prevented.

  Further, according to the present embodiment, the threaded portion for engaging the lid member for the main body container provided on the outer peripheral surface 21 a of the mouth portion 21 of the main body container 2 is engaged with the spout 4 of the refill container 1. It can be diverted as the screw part 22 for doing. Thereby, it is not necessary to newly provide a threaded portion for engagement with the refill container 1 on the main body container 2 side, and the structure of the main body container 2 is not complicated and the manufacturing cost is not increased.

  Further, in the present embodiment, in particular, the spout 4 of the refill container 1 has an inner cylinder part 44 for pouring out the fluid for refilling on the radially inner side of the outer cylinder part 43. The inner tube portion 44 is inserted into the mouth portion 21 when the outer tube portion 43 is engaged with the outer peripheral surface 21 a of the mouth portion 21. Thereby, a fluid can be poured into the inner part of the main body container 2 via the inner cylinder part 44 at the time of refilling. Moreover, as a result of pouring the fluid into the inner part in this way, it is possible to prevent the fluid from leaking and scattering through the air circulation hole 46 of the outer cylinder portion 43 during refilling. Further, since the outer diameter d2 of the inner cylinder portion 44 is smaller than the inner diameter d4 of the mouth portion 21 of the main body container 2, the inner circumference of the mouth portion 21 can be obtained when the inner cylinder portion 44 is inserted into the mouth portion 21. A gap S can be formed between the surface 21 b and the outer peripheral surface 44 b of the inner cylinder portion 44. Thereby, the air in the main body container 2 at the time of refilling can be smoothly exhausted through the said clearance gap S and the air circulation hole 46 of the outer cylinder part 43, and smooth refilling can be performed.

  In the present embodiment, particularly, the refill container 1 includes the lid member 5. The lid member 5 has a screw portion 51 that can be screwed to the screw portion 45 provided on the inner peripheral surface 43 c of the outer cylinder portion 43 on the outer peripheral surface 52, and the screw portion 51 and the screw portion 45 are connected to each other. By screwing, it engages with the inner peripheral surface 43 c of the outer cylinder part 43 and closes the opening 44 a of the inner cylinder part 44. Thereby, the leakage / scattering of the fluid from the refill container body 3 when not in use can be prevented by closing the spout 4 with the lid member 5 except when refilling. Moreover, since the air circulation hole 46 can be obstruct | occluded together, it can suppress that the air circulation hole 46 raise | generates clogging with dust, dust, etc. when the refill container 1 is not used. Further, since the lid member 5 can be repeatedly attached to and detached from the outer cylinder portion 43, the used refill container 1 is recovered after the refilling is completed and newly refilled with a fluid for refilling. It can be used. As a result, the waste in the refill container 1 can be reduced and the load on the environment can be reduced.

When the outer cylinder portion 43 of the refill container 1 is engaged with the mouth portion 21 of the main body container 2, the membrane member 47 is broken by the protrusion 64 of the opening member 6 provided on the main body container 2 side. The opening 44a of the cylindrical portion 44 is opened.

  The opening member 6 is configured as a separate member from the main body container 2 in this modification, and is used by being attached to the mouth portion 21 of the main body container 2. The structure similar to that of the opening member 6 may be provided integrally with the main body container 2. As shown in FIG. 5, the unsealing member 6 has a cylindrical portion 61, and a flange portion 62 having a larger diameter than the outer diameter of the cylindrical portion 61 is provided at the upper end portion of the cylindrical portion 61. It has been. The flange portion 62 is adapted to be locked to the tip of the mouth portion 21 when the cylindrical portion 61 is inserted into the mouth portion 21 of the main body container 2, whereby the opening member 6 is attached to the mouth portion 21. Is done. Further, the inner diameter of the cylindrical portion 61 is larger than the outer diameter d2 of the inner cylindrical portion 44, and when the outer cylindrical portion 43 is engaged with the mouth portion 21, the inner peripheral surface of the cylindrical portion 61 of the unsealing member 6. A gap S <b> 1 can be formed between the outer circumferential surface 44 b of the inner cylinder portion 44 (see FIG. 6C).

The protruding portion 64 has a plurality of groove portions 64a at the distal end portion, and has a shape that prevents clogging when the membrane member 47 is broken and can be reliably opened. The support member 63 has a substantially cross shape, and a plurality of openings 65 are formed on the lower end side of the cylindrical portion 61 to ensure a flow path for the fluid.

  Next, the engaging operation between the spout 4 and the mouth portion 21 will be described with reference to FIG. First, a lid member (not shown) for the main body container is removed from the mouth portion 21 of the main body container 2, and the opening member 6 is attached to the mouth portion 21. Next, the lid member 5 is removed from the spout 4 of the refill container 1. Then, as shown in FIG. 6A, the refill container 1 is turned upside down, and the outer cylinder part 43 is inserted into the mouth part 21 while the inner cylinder part 44 of the spout 4 is inserted into the mouth part 21 of the main body container 2. 21. At this time, since the opening 44a of the inner cylinder portion 44 is sealed by the membrane member 47, the fluid does not leak or scatter. And as shown in FIG.6 (b), the refill container 1 turned upside down is mounted on the main body container 2. As shown in FIG. At this time, the screw portion 45 of the outer cylinder portion 43 and the screw portion 22 of the mouth portion 21 have not yet been screwed together, and the protruding portion 64 of the unsealing member 6 has not yet reached the membrane member 47. Therefore, the opening 44a of the inner cylinder part 44 is still sealed.

  Thereafter, when the spout 4 is rotated together with the refill container main body 3 and the screw part 45 of the outer cylinder part 43 and the screw part 22 of the mouth part 21 are screwed together, the outer cylinder part 43 is lowered while the spout 4 is lowered. Engage with the outer peripheral surface 21 a of the mouth 21. When this engagement is completed, as shown in FIG. 6C, the protrusion 64 of the opening member 6 reaches the membrane member 47, the membrane member 47 is broken, and the opening 44a of the inner cylinder portion 44 is opened. Thereby, the fluid flows through the flow path F of the spout 4 and the cylindrical member 61 of the opening member 6, and is poured out into the main body container 2 from the opening 65 at the lower end. At this time, the air in the main body container 2 is exhausted through the gap S1 and the air circulation hole 46 of the outer cylinder portion 43, so that the fluid is smoothly injected into the main body container 2.

  According to the above modification, even when the refill container 1 is turned upside down and the outer cylinder portion 43 is engaged with the mouth portion 21 as described above, the refilling flow is performed by the membrane member 47 until the outer tube portion 43 is engaged. The body can be prevented from being poured out from the inner cylinder portion 44, and the dispensing can be started immediately after the engagement. Accordingly, it is possible to more reliably prevent leakage and scattering of the fluid during refilling.
