Description

  The present invention relates to a refill container, and is intended to efficiently refill the contents without causing leakage of the contents or dirtying hands or clothes.

  As containers for shampoos, rinses, detergents, deodorizers, cosmetics, etc., many containers equipped with a discharge device such as a pump have been put on the market in order to make it possible to take out an appropriate amount. After using up all the time, it is normal to transfer new contents from a refill container that is sold separately and reuse the original container (the container to be refilled). Is effectively utilized (see, for example, Patent Document 1).

  By the way, the refill container is originally a pouch-type container or a thin-walled blow molded product such as a low-strength (low rigidity) container, and it is difficult to refill the contents. Although various proposals have been made so far, such as transferring the contents after connecting two containers via screws, the conventional refill containers take time to refill. The current situation is that improvement is required.

It has become.

_On the outer peripheral wall of the inner peripheral wall 5a ₂ positioned at the lower end of the connecting cylinder g, there is a vertically long narrow groove h that forms a passage for air replacement with the connecting cylinder of the push-in member described later when refilling the contents. At least one is formed along the slit S, and outside air is taken into the container through the narrow groove h and the slit S to efficiently refill the contents. In the present invention, the case where the pouring tap 5 is used is illustrated, but if it can be linked with the original container and can transfer the contents in the refilling container, it is of the stopper type. However, the present invention is not limited thereto, and a type such as a cap provided with a nozzle head may be used.

Reference numeral 7 denotes a closing valve provided at the distal end of the insertion tube 5b. The closing valve body 7 is fixedly connected to and held by a fixing member 7a fitted by means such as undercut at the distal end portion of the insertion tube body 5b, and the fixing member 7a via a hinge 7b. the seat surface 5b ₁ formed on the tip portion side of the body 5b is composed of a valve body 7c for closing the pouring path e of contact with the contents, to one side or both sides of the valve body 7c, Figure 3 As shown in an external perspective view of the main part, a locking connecting thin piece 7d for connecting the valve body 7c and the fixing member 7a to each other is integrally provided (at least one is sufficient).

  The valve body 7c and the seating surface 5b can be lightly bonded or fused between each other (it is not necessary to be bonded or fused), thereby improving the sealing performance. . In addition, it is desirable that this adhesion or fusion has an adhesive strength and a fusion strength such that the valve main body 7c can be easily opened when the valve main body 7c is pushed in by a projection of an original container to be described later.

Connecting thin piece 7d is for maintaining a pre-opening attitude is brought into contact with the valve body 7c to the seat surface 5b ₁ (initial position), with the tilting of the valve body 7c by pushing the later-described push-in member Torn or stretched. Here, advance away can adhere to the valve body 7c and the seat surface 5b _1, have been fused, thereby enhancing the sealing property, the contents of the distribution stage of the products to prevent leakage.

  FIG. 4 is a view showing a container for transferring the contents of the refill container according to the present invention (the container whose contents are to be refilled and hereinafter referred to as the original container). In the figure, 8 is the original container, and 9 is a pushing member fixedly held in the mouth 8 a of the original container 8.

Pushing member 9, (composed of the outer cylinder 9a ₁ and the inner cylinder 9a _2.) Base to form an annular groove to insert the mouth portion 8a of the original container 8 and 9a, standing in the top wall of the base portion 9a, pouring a connecting tube 9b for engaging detachably with screws or undercut in the annular gap t of the plug 9 (see FIG. 2), the mouth center ties source container 8 via an arm L to the inner cylinder 9a ₂ of the base 9a a guide 9c which rises from its lower end region in parts, provided in a rising base end of the guide 9c, the closure valve body 7 is pushed toward the closed valve body 7 of the distal end portion of the insertion tube 5b from the seat surface 5b ₁ The protrusion 9d is configured to be separated and tilted in the content extraction path e.

The guide 9c is shown as an example of a semi-cylindrical shape having a guide surface f along the outer peripheral wall of the insertion tube 5b and having a tapered shape in which the region of the guide surface f is narrowed toward the tip. , the rise length from its proximal end, the refill container and the bottom plate 5a ₃ provided at the lower end of the inner peripheral wall 5a ₂ Note decene 5 in the set state to the original container 8 a length abutting As a result, the setting posture of the refill container with respect to the original container 8 is stabilized.

As shown in FIG. 5, the insertion tube 5b is inserted into the mouth 8a of the original container 8 along the guide surface f of the guide 9c, and the blocking valve body 7 is pushed in by the projection 9d as shown in FIG. The connected thin-walled piece 7d is gradually extended or broken, and the valve body 7c is tilted via the hinge 7b, thereby opening the feeding path e and the contents in the refill container. things refill air is introduced into the vessel (air displacement) contents are initiated through narrow groove h provided to the outer wall of the inner peripheral wall 5a ₂ simultaneously flows out to the original container 8.

  Then, when the original container 8 is filled with the contents and the contents reach the tip of the insertion tube 5b, the outflow of the contents automatically stops, and the container body 1 is moved as shown in FIG. The volume is reduced to the upper opening end 2a of the cylindrical body 2 (in the drawing, since the container body 1 is in the inverted posture, the upper opening end 2a is positioned on the lower side). Refilling is complete.

  When the refilling of the contents is completed and the insertion tube 5b is pulled out, the valve body 7c returns to its original posture due to its own weight and the pressing force of the remaining contents, and the gap formed by opening the feeding path e is Since it is closed, even if the contents remain in the container body 1, it does not drip easily. When the connecting thin piece 7d is formed of an elastic member such as a leaf spring, the valve body 7c returns to its original posture by its restoring force.

When the contents are refilled, air is introduced into the container through the passage formed by the narrow groove h (air replacement). If the container body 1 is reduced in volume as the contents are discharged, Even if the narrow groove h is not provided, refilling can be performed without any particular problem. 2, the installation position of the bottom plate 5a ₃ of the spout tap 5 is the vertical center of the outer peripheral wall 5a ₁ (the position corresponding to the tip of the connecting cylinder 9b of the pushing member 9). By doing so, it is possible to prevent the contents from remaining in the annular groove 5c as much as possible when refilling is completed and the container is returned to the normal position.

  In order to refill the contents remaining in the container body 1, the volume-reduced container body 1 is stretched (it may be stretched with either the mouth portion 1 a of the container body 1 or the region near the bottom of the trunk portion 1 b). Then, the insertion tube 5b is inserted again into the mouth 8a of the original container 8 along the guide surface f of the guide 9c, and the closing valve body 7 is pushed in by the projection 9d to open the feeding path e and refill. What is necessary is just to discharge the contents in the container to the original container 8.

  In the illustrated example, the length of the cylindrical body 2 has a length that surrounds the lower half of the body of the container body 1, and the contents filled in the cylinder 2 are refilled in two portions. Although shown, the length of the cylinder 2 can be arbitrarily changed, and is not limited to the case of refilling divided into two times.

  In addition, the valve body 7c of the closing valve body 7 is shown as an example in which the valve body 7 is connected and held so as to be swingable via the hinge 7b. However, the valve body 7 forms a plurality of weakened portions, and A slit type that breaks the valve body 7 and opens the feeding path e may be applied.

Incidentally, refill container according to the present invention has been described for the case of applying the Note decene as a means for discharging the contents, before opening of the container is in contact with the seat surface 5b _1, original container 8 it is possible to appropriately change the shape as long as the valve body 7c away from the seat surface 5b ₁ is present, may be applied, for example, those of the nozzle type when the projection 9d is pushed .

  It is possible to provide a refill container that can prevent the contents from falling off and adhere to hands and clothes and that can transfer the contents under a simple operation.
