Description

The present invention relates to a refill container and a lid, and relates to a refill container and a lid on the side of supplying contents such as powder and fluid to a main body container used daily.

Conventionally, from the viewpoint of resource saving and product price reduction, after consuming the contents of the main body container, the contents filled in the refill container are refilled into the main body container and the main body container is reused. ing.

As the refill container, a pouch bag, a tube, a thin bottle, or the like is used, and the consumer refills the contents into a predetermined main body container and uses it.

However, when an attempt is made to refill the contents using these refill containers, the spout cannot be successfully guided to the mouth of the main body container, and the contents may overflow. Even if the guidance is successful, if the refill container is a pouch or the like, the container itself is not taut, so both the main body container and the refill container must be fixed until the refill is completed. Therefore, an attempt is made to screw the refill container into the main body container (Patent Documents 1 and 2) or insert the injection nozzle of the refill container into the inside of the mouth of the main body container to make the refill container self-supporting (Patent Documents). 3) is done.

When the refill container is screwed into the main body container as in Patent Documents 1 and 2, the refill container and the main body container do not come off, but the vent is not secured. In the middle of refilling, the inflow speed of the contents slows down, and in the worst case, the inflow may stop. In such a case, the consumer tries to promote the inflow of the contents by pushing the side surface of the refill container or the like. Then, if the content contains a surfactant or the like, the content foams, making refilling more difficult.

When the pouring nozzle of the refill container is inserted into the mouth of the main body container as in Patent Document 3, the refill container itself can easily stand on its own, but the refill container is substantially upright. Therefore, when the contents are fluid, the contents and air are not smoothly replaced during refilling, and the inflow amount of the contents at the time of refilling is not stable, and as a result, there is a risk that the main container will fall over. There is.

Hereinafter, examples of the present invention will be specifically described with reference to the drawings, but it goes without saying that the present invention is not limited to the examples. In each figure, the same reference numerals represent the same or equivalent components.
Further, since the refill container and the lid used in the present invention can be expected to have the same effect as long as they have the same structure, the refill container will be mainly described.

The type of the refill container used in the present invention is not particularly limited as long as it does not hinder the independence at the time of refilling. It may be a tube container, a thin bottle container, or a thick bottle container. It may be appropriately selected depending on the type of contents. In the present invention, it is possible to refill the contents without pushing the side of the refill container, but if the contents are highly viscous, it is said that the material is flexible. It is preferable because it is easy to squeeze.

The contents contained in the refill container of the present invention are not particularly limited. It may be a fluid such as a lotion, a beauty essence, a milky lotion, a softener, a liquid detergent, or a solid such as granules, powder, or tablets. Although it can be appropriately selected depending on the intended purpose, the present invention is particularly effective when the content is a fluid.

The spout of the spout of the refill container of the present invention can be sealed by any means as long as the contents do not flow out during transportation or the like. For example, it can be sealed with a seal, a screw lid, a sealing member with a pull ring, or the like.

FIG. 1 is a diagram showing an example of refilling using the refill container of the present invention. Any container can be used as the main body container 1 itself that is used on a daily basis. The sealed portion (not shown) of the spout of the refill container 10 of the present invention is opened, the tip of the spout tube (spout 40) of the refill container is inserted into the main body container mouth 5, and the refill container 10 is in an inverted state as it is. To. Due to the presence of the ribs on the side surface of the spout tube (not shown), the refill container 10 can be inverted while a certain space is secured between the inner diameter of the main body container port 5 and the outer diameter of the spout tube 20. it can.

The size and inner diameter of the spout tube 20 of the present invention are not particularly limited. It can be adjusted as appropriate according to the dosage form of the contents. The height of the spout tube 20 of the present invention is not particularly limited. It may be set appropriately in relation to the shape of the main body container mouth 5 and the height of the mouth, but if the design is made higher than the height of the main body container mouth, the stringing phenomenon does not occur even if the content is viscous. Therefore, it is preferable.

In the present invention, an upright wall 60 having a notch 60a is provided on the outer periphery of the spout tube 20. In order to perform refilling, the tip of the spout tube 20 (spout port 40) can be easily inserted into the main body container port 5 by aligning the main body container port 5 with the notch 60a. As a side effect, when removing the sealing member of the refill container, a finger can be inserted, so that the sealing member can be easily removed.

The upright wall 60 is provided on the outer periphery of the spout cylinder 20, and the diameter thereof is not limited as long as the size of the main body container mouth portion 5 to which the contents are refilled can be included in the upright wall.
The shape and size of the notch 60a are not particularly limited. It is appropriately adjusted according to the shape and size of the mouth of the main container to be refilled.
One notch 60a is sufficient, but a plurality of notches 60a may be provided. Further, when a plurality of cutout portions 60a are provided, it is not necessary to make all the cutout portions 60a have the same shape, and different shapes may be used. It is preferable to use different shapes because it is easy to correspond to the shape of the mouth of an arbitrary main body container.

When sealing the tip of the spout tube (spout 40) with a seal p or the like, the orientation of the seal p may vary when the refill container is filled with the contents and sealed, and the notch is provided. The positions of the handles of 60a and the seal p are not substantially aligned, and the seal p is difficult to peel off. In such a case, if there are a plurality of cutout portions, it is preferable that the positions of the cutout portion 60a and the handle portion of the seal p are substantially aligned with each other (see FIG. 4).

The ribs of the present invention are provided at least two places on the side surface of the spout cylinder 20, and at least one place on the shoulder portion 70 of the container near the root of the spout cylinder 20. For convenience, the rib provided on the side surface of the spout tube 20 is referred to as "spout tube side rib 30a", and the rib provided on the container shoulder 70 near the base of the spout tube is referred to as "shoulder rib 30b". When these structures are provided on the lid, the ribs provided on the side surface of the spout cylinder 20 of the lid are "lid spout cylinder side ribs 30c" and the lid top surface 80 for convenience, and the spout cylinder of the lid is provided. The rib provided near the root of 20 is referred to as "lid top surface rib 30d".
If the spout cylinder side rib 30a (the same applies to the lid spout cylinder side rib 30c) is provided, the inner diameter of the main body container mouth 5 and the pouring cylinder when the refill container 10 is inverted on the main body container mouth 5 Independence can be stabilized by keeping a constant distance from the outer diameter of 20.
It is preferable to provide at least two or more spout tube side ribs 30a (the same applies to the lid spout tube side rib 30c), and it is preferable to provide three spout tube side ribs 30a from the viewpoint of cost effectiveness.

It is preferable to provide at least one shoulder rib 30b (the same applies to the lid top rib 30d). When the refill container 10 is inverted on the main body container 1, it acts as a vent. Any method may be provided to achieve this purpose, but it is preferable to provide three or more locations radially from the peripheral end of the spout tube toward the outer periphery in a plan view because the inverted state is likely to be stabilized ( (See FIG. 6).

The positional relationship between the spout tube side rib 30a and the shoulder rib 30b (the same applies to the relationship between the lid spout tube side rib 30c and the lid top surface rib 30d) is not particularly limited. It may be extended or divided and arranged. When a plurality of ribs are provided, ribs arranged separately from the extended ribs may be provided. It is preferable to extend it in terms of cost and ease of molding.

The height h of the shoulder rib 30b of the present invention refers to the height of the shoulder rib 30b from the shoulder 70 (see FIG. 5). In the case of the height of the lid top surface rib 30d, it corresponds to the height of the lid top surface rib 30d from the lid top surface 80. Hereinafter, the height of the shoulder rib 30b and the height of the lid top surface rib 30d are simply referred to as the rib height h. The height h of these ribs is not particularly limited as long as ventilation can be easily performed, but when two or more shoulder ribs (the same applies to the lid top rib) are provided, at least one of them is the height of the other rib. It is preferable that it is different from h. Specifically, if there are two locations, it means that the heights of the two ribs are different. For example, if there are three locations, one location is 1 mm, the remaining two locations are 1.2 mm, if there are four locations, one location is 1 mm, the other three locations are 1.2 mm, or two locations are 2 mm. It is conceivable that the other two locations are 2.5 mm. That is, when three or more places are provided, the height h of the rib may be two kinds. The difference in height may be such that when the refill container is inverted at the mouth of the main body container, it is self-supporting but slightly tilted, depending on the size and shape of the main body container and the refill container. Although different, it is preferably 0.5 mm to 2.5 mm, more preferably 1 mm to 2 mm. Within this range, when the refill container is inverted at the mouth of the main body container, the refill container is slightly tilted but does not fall, and air exchange at the time of refilling is smoothly performed, which is preferable.

The partition piece 50 of the present invention is provided inside the refill container and near the spout tube root mouth portion 21. It is provided for the purpose of smoothly filling the main body container 1 when the contents are refilled.
Although the principle is not clear, it is presumed that the presence of the partition piece 50 makes it easy for the contents to form a substantially spiral flow when the contents are refilled in the main container, which facilitates the refilling. However, it is not essential that the contents are filled in a substantially spiral shape.
The size, shape, strength, and placement location of the partition piece 50 can be appropriately changed depending on the type of contents, viscosity, and the like. For example, the partition piece 50 having a substantially plate shape (length 8 mm × width 15 mm) can be provided in a straight line or an arc shape. The strength of the partition piece 50 may be such that it is not deformed or swayed by the flow of the contents.

Regarding the relationship with the spout tube root port portion 21, it is preferable to provide the spout tube root port 21 at a certain distance from the outer circumference of the spout tube root port 21, although it depends on the inner diameter of the spout tube root port 21.
Specifically, the center of the spout tube root mouth portion 21 and both ends of the partition piece 50 are connected by a line, and the distance from the outer circumference of the spout tube root port portion 21 to the partition piece 50 (see FIGS. 11; d1 and d2). However, it is preferably provided at least 0.1 mm, preferably 0.2 mm or more apart. Although d1 and d2 may be the same (d1 = d2) or different (d1> d2, d1 <d2), it is better to provide them differently as shown in FIG. 8 (b). Is preferable because the contents tend to form a substantially spiral flow when refilling the main body container. In this case, the shorter distance may be at least 0.1 mm or more (for example, d1> d2 ≧ 0.1 mm).

However, if the partition piece 50 is provided too far from the outer circumference of the spout tube base mouth portion 21, its effect may not be expected. Therefore, it is preferable that the partition piece 50 is a concentric circle having an inner diameter of 2/3 of the inner diameter of the container shoulder. It is preferable to provide the container in the region of concentric circles having an inner diameter of 1/3 of the inner diameter of the shoulder of the container (see FIG. 9). In other words, it is preferably provided in a region of 2/3 similar figures having the same center, preferably in a region of similar figures of 1/3.

Further, it is preferable that the partition piece 50 is provided in an arc shape rather than in a straight line shape. For example, the angle θ (see FIG. 10) formed by connecting the left end a of the partition piece 50, the center of the spout tube root opening portion 21 and the right end b of the partition piece 50 is preferably 25 ° or more and less than 180 °. More preferably, it is 30 ° or more and 120 ° or less. This range is preferable because the contents tend to form a substantially spiral flow.
If you want to set d1 and d2 to d1 ≠ d2, for example, after designing the partition piece 50 that satisfies the condition of the angle θ described above on the premise that d1 = d2, one end of the partition piece 50 is at least 0.1 mm. The partition piece 50 is preferably provided at a distance of 0.2 mm or more and is provided in a concentric region having an inner diameter of 2/3 of the inner diameter of the container shoulder, and more preferably in a concentric region having an inner diameter of 1/3 of the inner diameter of the container shoulder. It may be provided so that the whole fits.

Each part in the present invention may be individually produced and then bonded by an adhesive means, or may be integrally molded.

The lid 100 used for the refill container in the present invention basically has the same upper structure as the refill container 10 described above. Therefore, when the present invention is used as the lid 100, the lid with the spout tube 20 may have the above-mentioned structure (see FIG. 2). Hereinafter, examples will be given based on the refill container 10, but the case where the lid 100 is used will not be described in detail individually, but it goes without saying that the same can be considered.
