Description

  The present invention relates to a refill container, and is intended to efficiently transfer 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 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 are troublesome in refilling work, so the improvement Was demanded.

JP 2000-159249 A

  An object of the present invention is to propose a new refill container that can efficiently transfer contents without causing problems such as leakage of the contents.

The present invention includes a container body having a mouth portion connected to a filling space for contents, and a container body provided at the mouth portion of the container body, for discharging the contents in the filling space to the mouth portion of the container to be refilled. A refill container with a tap;
The spout tap is connected to the base of the container to be refilled, and is integrally connected to the base. An annular groove is formed between the base and opened upward. An insertion tube for feeding the contents in the filling space into the container to be refilled,
The insertion tube body is pivotally connected to and held by a hinge through a hinge, and is pushed inward by a pushing member provided in the container to be refilled, so that the contents are tilted toward the inside of the insertion tube body. This is a refill container characterized in that a closing valve body for opening the dispensing path is provided.

  In the above-mentioned refill container, the closing valve body is connected to and held by a fixing member that fits at the distal end portion of the insertion tube body and is swingably connected to the fixing member via a hinge, and the distal end of the insertion tube body It is preferable that the valve main body is configured to contact the seating surface formed in the portion and seal the content extraction path. In this case, the valve main body is interposed between the valve main body and the fixing member. A sealing posture is maintained by abutting against the seat surface, but a connecting thin-walled piece is provided that can be torn or stretched as the pushing member is pushed to allow the valve body to swing by a hinge. Is desirable.

  Further, the closing valve body is connected to the valve main body and the insertion tube body at a position opposite to the hinge to close the content extraction path, and can be separated as the pushing member is pushed in. A simple connecting piece can also be provided.

  As the container body, a container whose outer shape is not deformed regardless of the increase or decrease in the filling amount of the contents can be applied, but a thin-walled one that reduces as the filling amount of the contents decreases is applied. It is also possible to apply an insertion tube having an insertion length that reaches at least the lower end region (visible line) of the container to be refilled in the refilling posture of the contents.

  The insertion tube body of the refill container is inserted from the mouth of the container to be refilled, and the valve body is tilted via the hinge by pushing the tip portion with the pushing member, so that the content supply path is not opened for the first time. Therefore, the contents can be refilled with a simple operation. At the time of refilling the contents, the distal end portion of the insertion tube exists at the bottom of the mouth of the container to be refilled, so that the contents do not spill out or adhere to hands or clothes.

  Supplying the contents when the contents to be refilled reach the tip of the insertion tube by keeping the insertion tube at an insertion length that reaches at least the lower end of the mouth of the container to be refilled For example, when a refill container is filled with a large amount of contents in order to perform refilling multiple times, an appropriate amount of the contents can be discharged for each refill. .

  By providing a closing valve body that is swingably connected via a hinge at the distal end of the insertion tube body, the closing valve body returns to the initial posture when the insertion tube body is pulled out after refilling. The contents will not sag.

It is the figure which showed other embodiment of the refill container according to this invention.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 is a view schematically showing an embodiment of a refill container according to the present invention, and FIG. 2 is an enlarged view of a main part of FIG.

  Reference numeral 1 in the figure denotes a container body filled with the contents to be refilled. The container body 1 has a filling space M formed inside thereof, and an upper end 1a is provided with a mouth portion 1a connected to the filling space M, and the body itself is reduced as the filling amount of the contents is reduced. Blow-type or ultra-thin type blow bottles can be applied, but relatively rigid blow bottles that do not change the shape of the main body itself even if the filling amount of the contents is reduced may be used. .

  2 is an outlet 1 provided at the mouth 1a of the container body 1 and is applied to the mouth of the container to be refilled to discharge the contents in the filling space M. It is an overcap for preventing dust from adhering to the outer surface and maintaining a hygienic favorable state.

  As shown in FIG. 2, the spout 2 has an annular base 2a linked to the mouth of the container to be refilled, and the internal space of the container (original container) whose contents in the filling space M are to be refilled. An insertion tube body 2b having a feeding path e for feeding is formed, and an annular groove 2c opened upward is formed between the base 2a and the insertion tube body 2b. .

Base 2a includes a peripheral wall 2a _1, the bottom plate 2a of the peripheral wall 2a ₂ inner integrally connected to leave an annular gap t inside the outer peripheral wall 2a _1, connecting the insertion tube 2b at the lower end of the inner peripheral wall 2a _{2 3} , of which the inner peripheral wall 2a ₂ is integrally formed with a connecting cylinder g in which a plurality of open-end slits S cut in a direction along the axial center are provided at intervals around the inner peripheral wall 2a _2. When the original container and the refill container are connected, the distal end portion of the connecting tube g is elastically deformed, and the reciprocal force ensures the mutual connection.

_On the outer peripheral wall of the inner peripheral wall 2a ₂ located 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 pushing member described later when the contents are refilled. At least one is formed along the slit S. The 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 spout tap 2 is used is illustrated, but a nozzle head is provided as long as it can be linked to the original container and can transfer the contents in the refill container. A type such as a cap may be used.

Reference numeral 4 denotes a closing valve provided at the distal end of the insertion tube 2b. The closing valve body 4 is fixedly coupled to and held by a fixing member 4a fitted by means such as undercut inside the distal end portion of the insertion tube body 2b, and is swingably connected to the fixing member 4a via a hinge 4b. is composed of a valve body 4c which closes the tip opening abuts the seating face 2b ₁ formed on the tip portion side surface of the tube 2b, (or only one side.) on both sides of the valve body 4c, the 3 As shown in an external perspective view of the main portion, a locking connecting thin piece (rectangular thin piece) 4d for connecting the valve body 4c and the fixing member 4a to each other is integrally provided (at least one). Just need it.)

Incidentally, it can be kept in lightly bonded or fused in between the mutually valve body 4c and the seat surface 2b _1, thereby also increasing the sealing performance. In addition, it is desirable that this adhesion or fusion has an adhesive strength and a fusion strength that allow the valve body 4c to be easily opened when the valve body 4c is pushed in by a projection of an original container described later.

Connecting thin piece 4d is for maintaining the sealing posture (initial posture) is abutted against the valve body 4c to the seat surface 2b _1, along with the tilting of the valve body 4c by pressing of which will be described later pushing member It is torn or stretched (including plastic deformation and elastic deformation). Here, advance away can adhere to the valve body 4c and the seat surface 2b _1, have been fused, thereby enhancing the sealing property, the contents of the distribution stage of the products is prevented 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, 5 is the original container, and 6 is a pushing member fixedly held in the mouth 5a of the original container 5.

Pushing member 6, (composed of the outer cylinder 6a ₁ and the cylinder 6a _2.) Base to form an annular groove to insert the mouth portion 5a of the original container 5 and 6a, standing in the top wall of the base portion 6a, note decene screw the second annular gap t (see FIG. 2) or a connecting tube 6b to releasably engage the undercut, mouth central connection source vessel 5 via an arm L to the inner cylinder 6a ₂ of the base portion 6a, a guide 6c which rises from its lower end region in parts, provided in a rising base end of the guide 6c, separate the valve body 4c from the seat surface 2b ₁ is pushed towards the closed valve body 4 of the distal end portion of the insertion tube 2b, It is comprised from the protrusion 6d tilted within the content extraction path | route e.

Examples of the guide 6c include a semicircular cylindrical body having a guide surface f along the outer peripheral wall of the insertion tube 2b and having a tapered shape in which the region of the guide surface f is narrowed toward the tip. However, the rising length from the base end of the refilling container comes into contact with the bottom plate 2a ₃ provided at the lower end of the inner peripheral wall 2a ₂ of the spout tap 2 in the set state of the original container 5. The length is particularly effective, and this stabilizes the setting posture of the refill container with respect to the original container 5.

As shown in FIG. 5, when the insertion tube 2b is inserted into the mouth portion 5a of the original container 5 along the guide surface f of the guide 6c, and the valve body 4c is pushed in by the projection 6d as shown in FIG. The connecting thin-walled piece 4 is gradually extended or broken, and accordingly, the valve body 4c is tilted via the hinge 3b, whereby the feeding path e is opened and the contents in the refill container are removed. refill air is introduced into the vessel (air displacement) contents are initiated through narrow groove h provided the original inner peripheral wall 2a ₂ of the outer wall at the same time flows into the container 5.

  Then, when the original container 5 is filled with the contents and the contents reach the tip of the insertion tube 2b, air replacement is not performed, and the outflow of the contents automatically stops. The refilling into the container 5 is completed.

  When the refilling of the contents is completed and the insertion tube 2b is pulled out, the valve body 4c 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 feed path e is Since it is closed, even if the contents remain in the container main body 1, it does not drip easily. When the connecting thin piece 4d is formed of an elastic member such as a leaf spring, the valve body 4c 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. Also, FIG. 2, as shown in phantom in FIG. 4, corresponding to the installation position of the bottom plate 2a ₃ Note decene 2 to the tip of the coupling tube 6b of the outer central portion of the vertical walls 2a ₁ (pushing member 6 Position)), it is possible to prevent the contents from remaining in the annular groove 2c 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 insertion tube body 2b is inserted again into the mouth portion 5a of the original container 5 along the guide surface f of the guide 6c, and the closing valve body is formed by the projection 6d. 4 may be pushed to open the feeding path e and the contents in the refill container may flow out to the original container 5.

FIG. 7 is a view showing a main part of another embodiment of the refill container according to the present invention. 7 in figure provided at the edge of the valve body 4c, thin tongue leading to seating surface 2b ₁ of the insertion tube member 2b, 8 are provided on the edge of the opposing positions of the thin tongue 7, disconnect incapable A thin-walled tongue piece 9 bonded and fused is a hinge provided on the thin-walled tongue piece 8.

Refill container with such a configuration, prior to opening of the container, i.e., before pushing the valve body 4c, the thin tongue 8, adhered to the seating surface 2b ₁ of the insertion tube member 2b, it is in fused state The distal end opening of the insertion tube 2b is closed by the valve body 4c, but the insertion tube 2b is inserted into the mouth 5a of the original container 5 along the guide surface f of the guide 6c, and the projection 6d when the valve body 4c is pushed, as shown in FIG. 8, the thin tongue 7, in which the valve body 4c is tilted via the hinge 9 as well as away from the seat surface 2b ₁ of the insertion tube member 2b With this, the feed path e is opened, and the contents in the refill container flow out to the original container 5. Incidentally, the thin tongue 8 is bonded to the insert tube 2b seating surface 2b ₁ of, the case which has been fused by way of example, said thin tongue 8 fits with such engagement means of the undercut It may be fixed by.

Also in the refill container of this example, when the refilling of the contents is completed and the insertion tube body 2b is pulled out, the valve body 4c returns to its original posture due to its own weight or a pressing force by the remaining contents, and the insertion tube The front end opening of the body 2b is immediately closed, and even if the contents remain in the container body 1, it does not easily fall down. When the valve body 4c returns to the original position, the thin tongue 7 functions as a receiving portion of the valve body 4c in contact with the seat surface 2b _1.

Thin tongue 7 may be plurality if possible easy away from the seat surface 2b _1, is not limited in this regard. Further, the thin tongue 7 is able to be lightly bonded, fused to the seat surface 2b _1, thereby it is also possible to enhance the sealing property. As for the adhesion and fusion strength, it is desirable that the strength easily opens when the projection 6 d of the original container 5 is pushed in and is weaker than the thin tongue piece 8.

FIG. 9 is a view showing a main part of still another embodiment of the refill container according to the present invention. This example, the valve body 4c directly with fixing and holding the valve body 4c on the tip portion inside the insertion tube 2b by thin tongue 8, the distal end opening of the insertion tube member 2b is brought into contact with the seat surface 2b ₁ Closed.

Before opening of the container, the valve body 4c is separated capable contacts the seating surface 2b ₁ of the insertion tube member 2b (adhesion, the fused may not be or may be not.) Inserted though tube 2b However, the insertion tube 2b is inserted into the mouth 5a of the original container 5 along the guide surface f of the guide 6c, and the valve body 4c is tilted by the projection 6d. The front end opening of the body 2b is opened and the feeding path e is opened.

  Although the closing valve body 4 of the refill container according to the present invention is illustrated as a structure that is fixed from the inside of the insertion tube body 2b, the insertion tube body 2b is pulled out from the mouth portion 5a of the original container 5. In this case, as long as the valve body 4c can close the distal end opening of the insertion tube 2b, the valve body 4c may be fixed from the outside of the insertion tube 2b, and this point is not limited.

  In the refill container, all of the constituent members can be made of synthetic resin, and when the container is discarded, it is possible to save time and labor for separating the members.

As described above, it is possible to apply an elastic member such as a leaf spring to the locking connecting thin piece 4d that can be configured by a rectangular thin piece.掲図7, be one that can be applied in the refill container shown in FIG. 9, thereby it becomes possible to keep urging the direction for bringing the valve body 4c always the seating face 2b _1, Even if the contents remain in the container body 1 at the time of refilling, the container body 1 can be reliably sealed.

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 2b _1, original container 5 it is possible to appropriately change the shape as long as the valve body 4c away from the seat surface 2b ₁ is present, may be applied, for example, those of the nozzle type when the projection 6d 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.
