Description

  The present invention relates to a refill container.

Conventionally, as this type of refill container, as described in, for example, Patent Document 1 below, a container main body for storing contents to be refilled in this container, and a mouth mounted on the mouth of the container main body There is known a refill container that includes an inner stopper that closes the portion, and is refilled by screwing the inner stopper into the mouth of the container.
The above-described inner plug is formed with a spout for pouring out the contents and a seal portion for closing the spout. The seal portion is made of, for example, a lid provided with a pull top.

  In the refill container having the above-described configuration, for example, the pull top is first pulled up to open the spout of the inner plug. Subsequently, the refill container is placed in an upright posture (the mouth portion is in an upward posture), and the mouth portion of the main container in an inverted posture (the mouth portion is in a downward posture) is screwed onto the inner plug of the refill container. Thereafter, the refill container and the main container are reversed to bring the main container into an upright posture and the refill container into an inverted posture. As a result, the contents in the refill container are refilled into the main container through the insides of the mouths of the refill container and the main container.

JP 2000-159249 A

However, in the above-described conventional refill container, after opening the spout of the inner stopper, it is necessary to screw the mouth of the main container into the inner stopper, and then turn the refill container and the main container upside down. Work was easy to become complicated.
Also, since the mouth of the container is screwed into the refill container after opening the spout of the inner plug, if the refill container is accidentally tilted during the screwing operation, the contents in the refill container will spill. There was a risk of getting out.
Further, since the container is placed in an inverted position when the mouth of the container is screwed onto the inner plug, the contents in the container are likely to spill if the contents remain inside the container. Therefore, it was difficult to perform the refilling work unless the contents in the container were used up.

  The present invention has been made in view of such circumstances, and its purpose is that the refilling operation can be easily performed, and it is difficult to spill the contents during refilling. An object of the present invention is to provide a refill container that can be refilled even if it remains.

In order to achieve the above object, the present invention provides the following means.
(1) A refill container according to the present invention comprises a container main body in which contents to be refilled in the container are accommodated, a mounting cylinder attached to the mouth of the container main body, and an extraction cylinder in which an extraction hole is formed. A base cylinder member, and a lid cylinder member that is slidably mounted in the container axial direction on the extraction cylinder, closes the extraction hole, and is connected to the inlet portion of the main container, When the lid cylinder member is slid to the container body side with respect to the dispensing cylinder, the dispensing hole is opened, and the dispensing cylinder opens to the side. Are formed, and the inside of the extraction cylinder is directly connected to the extraction hole, and to the air introduction path that is directly connected to the air introduction hole and has a smaller channel cross-sectional area than the extraction path. A partition wall for partitioning is extended in the container axial direction.

  According to the refill container according to the present invention, the lid cylinder member is connected to the inlet part, and after the refill container and the main container are combined, the main body of the refill container and the main container are relatively aligned along the container axial direction. The cover cylinder member connected to the injection port portion can be slid to the container main body side with respect to the extraction cylinder by moving close to each other. Thereby, the pouring hole of the pouring cylinder which has been blocked can be opened, and the inside of the main body of the refill container and the inside of the main container can be communicated with each other through the pouring path. Therefore, the contents in the container main body can be poured into the main container through the pouring channel, and can be refilled into the main container.

  By the way, at the time of the above refilling, the inside of the container body of the refill container and the inside of the main container communicate with each other through the air introduction hole and the air introduction path. It is smaller than the extraction route. Therefore, the content can be made to flow by giving priority to the extraction path over the air introduction path, and refilling work can be performed using this extraction path as described above. In addition, this makes it possible to use the air introduction path as a route for air replacement, and to smoothly perform air replacement by smoothly flowing the air in the container toward the refill container. As a result, the contents can be refilled easily with little resistance.

In addition, as described above, after combining the refill container and the main container in a state where the cover cylinder member is connected to the injection port portion, a simple operation of relatively moving both containers closer to each other along the container axial direction. Since the contents can be refilled by this, the refilling operation can be facilitated.
In addition, since the lid cylinder member is connected to the injection port at the time of refilling, the refilling container can be combined with this container in a stable state, and the contents are not easily spilled. Furthermore, since the contents can be refilled into this container at the same time as opening the refill container, it is possible to perform refilling work without placing the container in an inverted position. For example, when the contents in the container remain Even so, the contents can be refilled.

(2) In the refill container according to the present invention, the air introduction hole may have an opening area smaller than the extraction hole.

  In this case, in addition to the flow passage cross-sectional area of the air introduction path being smaller than the flow passage cross-sectional area of the extraction path, the opening area of the air introduction hole is smaller than the opening area of the extraction hole. It is easy to flow an object to the main container side through the pouring path more preferentially, and it is easy to perform air replacement more smoothly using the air introduction path. Therefore, the contents can be refilled more easily.

(3) The refill container according to the present invention may further include a regulating member that is detachably attached to the dispensing cylinder and regulates the sliding movement of the lid cylinder member toward the container body.

  In this case, even if an external force is unexpectedly applied to the refill container at the distribution stage or the like, it is possible to restrict the sliding movement of the lid tube member and prevent the dispensing hole from being opened, and refilling is possible. The container can be prevented from being opened when it is not intended.

  According to the refill container of the present invention, the refilling operation can be easily performed, and it is difficult to spill the contents at the time of refilling, and the refilling work can be performed even when the contents in the container remain. It can be carried out.

It is a longitudinal cross-sectional view which shows embodiment of the refill container which concerns on this invention. It is AA sectional drawing shown in FIG. It is a longitudinal cross-sectional view which shows the state which combined the refill container shown in FIG. 1 with this container. It is a longitudinal cross-sectional view which shows the state which moved the refill container and this container relatively close to the container axial direction from the state shown in FIG. 3, and is refilling the contents.

Hereinafter, embodiments of a refill container according to the present invention will be described with reference to the drawings.
(Configuration of refill container)
As shown in FIG. 1, the refill container 1 of the present embodiment has a container main body 2 in which contents (not shown) to be refilled in the main container (see FIG. 3) are accommodated, and a mouth 2 a of the container main body 2 is closed. Top tube-shaped dispensing member (base tube member) 10, slide tube (lid tube member) 20 slidably mounted on the dispensing tube 14 of the dispensing member 10 in the container axis O direction, and dispensing A stopper (restricting member) 30 that is detachably attached to the tube 14 and restricts the sliding movement of the slide tube 20 toward the container body 2 is provided.

  In addition, the container main body 2, the pouring member 10, and the slide cylinder 20 described above are arranged in a state where their respective central axes are located on a common axis. In the present embodiment, this common axis is referred to as a container axis O, and in the refill container 1, the slide cylinder 20 side along the container axis O is referred to as the upper side, and the container body 2 side is referred to as the lower side. A direction perpendicular to the container axis O is referred to as a radial direction, and a direction around the container axis O is referred to as a circumferential direction.

  The dispensing member 10 includes an outer cylinder portion (mounting cylinder) 11 screwed to the outer surface of the mouth portion 2a of the container body 2, an inner cylinder portion 12 fitted in the mouth portion 2a of the container body 2, A connecting ring 13 that connects the upper end portion of the cylindrical portion 11 and the upper end portion of the inner cylindrical portion 12 and is in contact with the open end of the mouth portion 2 a, and a top-like cylindrical extraction tube 14 that is connected to the connecting ring 13. And.

  The extraction cylinder 14 has a lower end connected to the inner edge of the connection ring 13 and extends upward, a cylindrical peripheral wall 14a, and a top wall 14b that closes the upper opening of the peripheral wall 14a, It has. The outer cylinder portion 11 of the pouring member 10 has substantially the same diameter as the injection port portion 41 of the main container 40, and the extraction tube 14 has a diameter smaller than that of the injection port portion 41 of the main container 40. The size can be inserted into the portion 41.

As shown in FIGS. 1 and 2, an extraction hole 15 for extracting contents and an air introduction hole 16 for air replacement are formed on the side of the top wall 14 b of the peripheral wall portion 14 a of the extraction cylinder 14. Each is open to the side.
In the illustrated example, the extraction hole 15 and the air introduction hole 16 are formed so as to face each other in the radial direction with the container axis O interposed therebetween. However, the positional relationship between the extraction hole 15 and the air introduction hole 16 is not limited to this case, and may be formed at a position shifted in the circumferential direction. In the example shown in the drawing, the extraction hole 15 and the air introduction hole 16 are each formed in a rectangular shape when viewed from the side (other shapes such as a circular shape may be adopted). The opening area of the air introduction hole 16 is formed smaller than the opening area.

A plate-shaped partition wall 17 that divides the internal space of the extraction cylinder 14 into two is extended downward along the container axis O direction on the top wall portion 14 b of the extraction cylinder 14. Specifically, the partition wall 17 divides the inside of the extraction cylinder 14 into two parts, an extraction path R1 directly connected to the extraction hole 15 and an air introduction path R2 directly connected to the air introduction hole 16. Yes.
At this time, the partition wall 17 is disposed closer to the air introduction hole 16, and the flow path cross-sectional area of the air introduction path R2 is smaller than the flow path cross-sectional area of the extraction path R1.
As shown in FIG. 2, the channel cross-sectional area refers to the partition wall 17 on the same plane and the inner peripheral surface of the peripheral wall portion 14 a of the extraction cylinder 14 when the extraction cylinder 14 is viewed in cross section. The sectional area S2 of the air introduction path R2 is smaller than the sectional area S1 of the extraction path R1.

  In the illustrated example, a gap is formed between the partition wall 17 and the inner peripheral surface of the peripheral wall portion 14a of the extraction cylinder 14, and the extraction path R1 and the air introduction path R2 are completely partitioned in the circumferential direction. Although the partition wall 17 may be in contact with or connected to the inner peripheral surface of the peripheral wall portion 14a of the extraction cylinder 14, the extraction path R1 and the air introduction path R2 may be completely partitioned in the circumferential direction.

  The slide cylinder 20 closes the extraction hole 15 and the air introduction hole 16 formed in the extraction cylinder 14 and is inserted into the injection port portion 41 of the container 40 and connected to the injection port portion 41. A slide cylinder that is a member that can surround the peripheral wall portion 14a of the dispensing cylinder 14 from the outside in the radial direction and can be slid in the container axis O direction while being guided (slid) by the peripheral wall section 14a. A main body 21 and an annular flange portion 22 projecting radially outward from the lower end of the slide cylinder main body 21 are provided.

  The upper end edge of the slide cylinder body 21 is substantially flush with the top wall portion 14 b of the extraction cylinder 14, thereby closing both the extraction hole 15 and the air introduction hole 16. The flange portion 22 is an annular member having a diameter larger than that of the inlet portion 41 of the container 40, and can be brought into contact with the opening edge of the inlet portion 41. The flange portion 22 is provided with a guide rib 23 that can be inserted into the injection port portion 41 of the container 40 and that is inscribed in the injection port portion 41.

  The guide ribs 23 are plate pieces projecting radially outward from the slide cylinder main body 21, and a plurality of guide ribs 23 are formed at intervals in the circumferential direction. In the illustrated example, four are formed at intervals of 90 degrees in the circumferential direction. These guide ribs 23 are formed with rounded upper ends, and can be inserted into the inlet 41 of the container 40 with little resistance.

As shown in FIG. 1, the stopper 30 is formed in a C shape in cross section, and can be elastically deformed by surrounding the peripheral wall portion 14 a of the dispensing cylinder 14 from the outside in the radial direction and fitting the peripheral wall portion 14 a inside. And a gripping piece 32 protruding from the C ring portion 31 toward the outside in the radial direction.
The stopper 30 is disposed between the connecting ring 13 of the pouring member 10 and the flange portion 22 of the slide cylinder 20, and as described above, the slide movement of the slide cylinder 20 toward the container body 2 is performed. Is regulated. The gripping piece 32 is formed so as to be positioned on the opposite side of the opening 31a of the C ring portion 31 with the container axis O interposed therebetween.

(Use of refill containers)
Next, a method for refilling the contents from the refill container 1 configured as described above into the main container 40 will be described.

First, the refill container 1 is placed above the main container 40 in a state where the refill container 1 is in an inverted posture and the main container 40 is in an upright posture. Then, the refill container 1 and the main container 40 are relatively moved closer to each other in the direction of the container axis O while aligning them, and as shown in FIG. 3, the upper end portion of the pouring cylinder 14 of the pouring member 10 and the slide cylinder 20. The slide cylinder body 21 is inserted into the inlet 41 of the container 40 and the flange 22 of the slide cylinder 20 is brought into contact with the opening edge of the inlet 41.
Thereby, the slide cylinder 20 can be connected to the inlet part 41, and the refill container 1 and the main container 40 can be combined. In particular, since the flange portion 22 of the slide cylinder 20 contacts the opening edge of the injection port portion 41 and the guide rib 23 is inscribed in the injection port portion 41, the connection can be stabilized.

Here, in this embodiment, the refill container 1 is turned upside down as described above, so that the top and bottom of the refill container 1 are inverted. The 20 side is the lower side, and the container body 2 side is the upper side.
Further, since the dispensing hole 15 and the air introduction hole 16 of the refill container 1 are both closed (for example, liquid-tight and air-tightly sealed) by the slide cylinder 20, the container main body 2 can be used even when the refill container 1 is in an inverted posture. The content inside does not flow out through the extraction hole 15 and the air introduction hole 16.

  And after combining the refill container 1 and this container 40, the stopper 30 is removed from the extraction pipe | tube 14 of the extraction | pouring member 10 using the holding piece 32, and the restriction | limiting of the slide movement of the slide cylinder 20 is cancelled | released. Then, as shown in FIG. 4, the container main body 2 of the refill container 1 and the main container 40 are relatively moved along the container axis O direction. Thereby, the slide cylinder 20 connected to the injection port portion 41 can be slid to the container main body 2 side with respect to the extraction cylinder 14, and the upper end portion of the extraction cylinder 14 is placed in the main container rather than the slide cylinder 20. 40 can be moved inside. For this reason, the pouring hole 15 and the air introduction hole 16 of the pouring cylinder 14 closed by the slide cylinder 20 are both opened.

  Therefore, since the inside of the container main body 2 of the refill container 1 and the inside of the main container 40 communicate with each other through the extraction hole 15 and the extraction path R1, the contents accommodated in the container main body 2 of the refill container 1 are transferred to this extraction path. It can be poured into the main container 40 through R1 (arrow A shown in FIG. 4), and the contents can be refilled from the refill container 1 to the main container 40.

  By the way, at the time of the above refilling, the inside of the container body 2 of the refilling container 1 and the inside of the main container 40 communicate with each other through the air introduction hole 16 and the air introduction path R2. The partition wall 17 provided is designed to be smaller than the above-described extraction path R1. Therefore, the content can be made to flow by giving priority to the extraction path R1 over the air introduction path R2, and the refilling operation can be performed using the extraction path R1 as described above. Moreover, by this, the air in this container 40 can be smoothly flowed to the refill container 1 side using air introduction path R2, and air replacement (arrow B shown in FIG. 4) can be performed favorably.

As a result, the contents can be refilled easily with little resistance. In particular, when the contents are in the form of a cream with a high viscosity, it is considered that the contents are likely to flow to the side of the extraction path R1 having a larger flow path cross-sectional area than the air introduction path R2, and thus the above-described effects are remarkably achieved. Can be made.
In addition, in the case of this embodiment, in addition to the channel cross-sectional area of the air introduction path R2 being smaller than that of the extraction path R1, the opening area of the air introduction hole 16 is smaller than that of the extraction hole 15, At the time of refilling, the contents can be more preferentially flowed to the main container 40 side through the extraction path R1, and air replacement can be performed more smoothly using the air introduction path R2.

  If the container body 2 of the refill container 1 and the main container 40 are moved relatively close to each other, the connecting ring 13 of the extraction member 10 and the flange portion 22 of the slide cylinder 20 come into contact with each other, so that the approaching movement is restricted. Is done.

As described above, according to the refill container 1 of the present embodiment, after the refill container 1 and the main container 40 are combined in a state where the slide cylinder 20 is connected to the injection port portion 41, the main container 2 and the main container 40 are combined. Can be refilled by a simple work of relatively moving the container along the container axis O direction, so that the refilling work can be facilitated.
Further, since the flange portion 22 of the slide cylinder 20 is brought into contact with the opening edge of the injection port portion 41 at the time of refilling, the refillable container 1 in the inverted posture can be combined with the main container 40 in a stable state. Since the guide rib 23 of the slide cylinder 20 is inscribed in the inlet 41, the refill container 1 and the main container 40 can be combined without being displaced in the radial direction. Therefore, it is possible to effectively suppress the contents from spilling from these.

  Furthermore, since the contents can be refilled in the main container 40 at the same time as the refill container 1 is opened, it is possible to perform the refilling operation without placing the main container 40 in an inverted position, for example, the contents in the main container 40. Even if an object remains, the contents can be refilled.

  Further, as shown in FIG. 1, since the stopper 30 is mounted on the dispensing cylinder 14 of the dispensing member 10 to restrict the downward movement of the slide cylinder 20, it is assumed that an external force is unexpectedly applied to the refill container 1 at the distribution stage or the like. Even if the is added, it is possible to restrict the sliding movement of the slide cylinder 20 to prevent the discharge hole 15 and the air introduction hole 16 from being opened, and the refill container 1 is opened unexpectedly. Can be suppressed.

  The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

For example, the container main body 2 and the main container 40 may be formed so as to be squeezable and thin, and the refilling operation may be performed while the squeeze is deformed.
In addition, although the case where the opening area of the air introduction hole 16 is formed smaller than the opening area of the extraction hole 15 is described as an example, the present invention is not limited to this case, and the same opening area may be used. It may be formed larger than the opening area of the outlet hole 15. Even in these cases, since the flow passage cross-sectional area of the air introduction path R2 is smaller than the flow passage cross-sectional area of the extraction path R1 due to the partition wall 17, air replacement is reliably performed using the air introduction path R2. While performing, the contents can be preferentially flowed into the extraction path R1, and the refilling operation can be easily performed. However, the opening area of the air introduction hole 16 is preferably smaller than the opening area of the extraction hole 15.

  Moreover, although the partition wall 17 is formed in a plate shape, it may be formed in, for example, an arc shape or an S shape in a cross section. Regardless of the shape, the inner space of the extraction cylinder 14 is partitioned into an extraction path R1 and an air introduction path R2, and the flow path cross-sectional area of the air introduction path R2 is more than the flow path cross-sectional area of the extraction path R1. It doesn't matter if it gets smaller.

Moreover, in the said embodiment, although the pouring member 10 was made into the structure screwed with respect to the opening 2a of the container main body 2 via the outer cylinder part 11, it is not restricted to screwing, It is not restricted to the opening 2a. It only has to be installed. For example, it may be attached by undercut fitting or other methods.
In addition, although the stopper 30 is fitted to the extraction cylinder 14 of the extraction member 10 using the C ring portion 31, the stopper 30 may be integrally formed with the extraction member 10 and the slide cylinder 20. In this case, for example, the stopper is integrally formed through an easy breaking portion such as a weakened portion, and the stopper is detached while breaking the easy breaking portion, thereby releasing the restriction on the slide movement of the slide cylinder 20. Adopt it.
