Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a double container in which an inner container is replaceably mounted in an outer container.

[0002]

[Prior art]

 The outer container is a container for cosmetics, medicines, etc., which is made by using a high manufacturing cost or using an expensive material for the purpose of enhancing the product image and protecting the contents from sunlight. It is not preferable from the viewpoint of resource saving to dispose of the entire container that has been filled with the inner container with the contents filled in, and it is not preferable to dispose of the entire container. This will increase the financial burden on the person.

Therefore, when the contents have been used up, the inner container is removed from the outer container, and a new inner container filled with the contents is provided inside the outer container, so that the outer container can be repeatedly used to save resources and the environment. It is considered to measure protection and economy, and as one of them is described in Japanese Utility Model Publication No. 3-54019, an inner container having a flange portion on a shoulder portion is provided at the opening edge of the outer container. It is proposed that the flange is placed on the interior, and the inner container is pressed and fixed by the cap screwed into the outer container.

According to the double container having such a configuration, the above-mentioned object can be achieved by making the inner container disposable and repeatedly using the outer container. However, when removing the inner container, the lid body is removed. After removing the cap and removing it from the outer container, or when installing a new inner container, remove the lid, insert the cap into the outer container and screw the cap into the outer container to fix the inner container to the lid. Each requires the steps of screwing in.

That is, the lid of the inner container closes the opening until the contents are used up, and is removed each time the contents are taken out. The lid and the cap are provided for the inner container and the outer container, respectively. Since the inner container is not fixed if the cap is screwed in insufficiently because it is screw-fitted, it is difficult to open the inner container because it rotates together when the lid is rotated to remove the contents. This may cause the inconvenience of turning together and removing from the outer container.

[0006]

[Problems to be solved by the device]

 The problem to be solved by the present invention is that the procedure for replacing the inner container, which has the conventional double container in which the inner container can be replaced, is extremely troublesome, and the cap of the outer container must be completely screwed in. It is difficult to open the container and there is a problem in taking out the contents.

[0007]

It is configured to hold the interior.

[0009]

[Action]

 Holding the lid mounted on the inner container and the outer container or the connecting member, the engaging protrusion and the engaging groove and the introducing groove are in the same phase, so that the inner container can be taken in and out of the outer container for replacement, and When the fitting protrusion is fitted in the engaging groove, the lid or the connecting member is turned to fix the inner container to the outer container. Then, the inner container can be replaced and fixed with a slight rotation of the lid or the connecting member, and the contents can be taken out with the inner container fixed using the outlet of the lid.

[0010]

Embodiment 1 FIGS. 1, 2, and 3 show an embodiment of the invention described in claim 1, in which a lid body 1 is provided with an internal thread 3 on an inner peripheral surface thereof and is placed at a centrally symmetric position. A flange 5 having two engaging projections 4 is provided on the outer peripheral surface of the base end, and a covering flange 6 having a diameter slightly larger than the outer edge of the engaging projections 4 is provided slightly above it. This is a configuration in which the tube portion 2 is equipped with a dispenser 9. That is, the dispenser 9 is attached to the stem 11 protruding upward of the pump casing 10 fixed to the top wall 7 of the tubular portion 2, and is pushed inside the guide tube 8 extending above the top wall 7 to slide inside. It is a well-known one in which the suction tube 13 sucks up the contents by pushing down the button 12 and releasing it, and takes out the contents from the outlet port 14 composed of the nozzle of the push button 12.

The inner container 16 is composed of a container body 17 having a bottomed cylindrical shape and a mouth portion 19 formed to project through a shoulder portion 18 at the top thereof, and the female screw 3 of the cylinder portion 2 is attached to the outer peripheral surface of the mouth portion 19. A male screw 20 for screw-fitting is provided.

The outer container 21 is composed of a body wall 22 and a bottom wall 23 of a size that allows the container body 17 of the inner container 16 to be loosely housed inside, and has a bottomed cylindrical shape with an open upper end, and expands outward at the upper end. The thickened portion 24 is formed, and two L-shaped engaging grooves 25 which are open to the inner peripheral surface are provided in the thickened portion 24 at central symmetrical positions, and the vertically extending portion is upward. The portion which is open to the side and extends laterally has a locking projection 26.

In the first embodiment having such a configuration, contents such as cosmetics and medicines are loaded into the inner container 16 and the contents are used up so that they are replaced with new ones when they are empty. Then, by covering the mouth portion 19 of the inner container 16 with the tube portion 2 of the lid body 1 and screwing the female screw 3 into the male screw 20, the suction pipe 13 reaches the bottom of the container body 17 and closes the mouth portion 19. The lid body 1 is attached to the inner container 16 in the closed state, and the container body 17 of the inner container 16 is inserted into the outer container 21 so that the engaging projection 4 is in the same phase as the vertically extending portion of the engaging groove 25. It is placed and fitted (FIG. 3A), and then it is rotated in the lateral direction to fix the engagement protrusion 4 in the depth of the engagement groove 25 by using the locking protrusion 26 as a retainer (FIG. 3B). The flange 5 has a diameter equal to or slightly smaller than the inner diameter of the body wall 22 and allows the outer container 21 to hold the lid 1 and the inner container 16 concentrically and stably.

In this state, the operation of depressing and releasing the push button 12 is repeated to take out the contents of the inner container 16 from the outlet 14, and when the contents are used up, the lid body 1 is pressed in the opposite direction. Then, the engaging protrusion 4 is disengaged from the engaging groove 25 by pulling up and then pulling up, the inner container 16 is pulled out from the outer container 21 as it is, the lid body 1 is removed, and only the inner container 16 is discarded.

The new inner container 16 loaded with the contents is sealed by a simple temporary lid body (not shown) screwed into the male screw 20 or attached to the rim, and the inner vessel is used after removing the temporary lid body. The lid body 1 removed from the above is mounted by screw fitting and held inside the outer container 21 as described above. Since the push button 12 is pushed down and released in the central axis direction to take out the contents, the inner container 16 does not rotate together.

[0016]

Embodiment 2 FIGS. 4 and 5 are different embodiments of the invention described in claim 1, in which a lid body 31 has a female thread 33 and a flange 35 having an engaging projection 34 and a covering flange 36 on a cylindrical portion 32. It is the same as the first embodiment in that it has, but has a top wall portion 37 that covers the opening of the mouth portion 20 of the inner container 16 and has an outlet port 38 provided at the center thereof and is fitted into the outlet port 38. The difference is that a cover body 40 having a plug body 39 that is inserted and sealed is attached to a top wall portion 37 by a hinge 41 so as to be capable of pivoting and undulating.

Further, the outer container 21 and the inner container 16 are the same as those of the first embodiment except that the engaging groove 42 of the outer container 21 is not L-shaped but has an inclined screw groove shape.

In the second embodiment having such a configuration, the inner container 16 having the lid body 31 mounted therein is retained inside the outer container 21 or is put in and out by simply inserting the engaging protrusion 34 into the engaging groove 42 and rotating the engaging protrusion 42. This can be done (FIGS. 5A and 5B), and since the outlet 38 is configured to open and close by undulating the cover body 40, the inner container 16 does not rotate together. The handling other than the above is the same as that of the first embodiment, and the lid 31 and the outer container 21 are repeatedly used.

[0019]

Embodiment 3 FIGS. 6, 7 and 8 show an embodiment of the invention described in claim 2, in which the lid body 1 and the inner container 16 equipped with the dispenser 9 on the tube portion 2 are the embodiments. The same reference numerals as in Example 1 are given to the corresponding portions.

The locking groove 51 has projections 52 and 53 that are provided near the both ends of the bottom in the circumferential direction.

A coupling member 55, which is composed of a ring body 56 that is fitted to the body wall 47 in a substantially dense manner and an inward flange 57 that covers the opening edge of the body wall 47, is formed on the inner peripheral surface of the ring body 56. The outer groove 46 is rotatably attached to the outer container 46 by fitting the annular groove 58 to the protrusion 49. The inward flange 57 of the coupling member 55 has an introduction groove 59 having the same plane size as the fitting groove 50 at the central symmetrical position, and the engaging piece 60 is projected downward at the central symmetrical position orthogonal to this. In addition, the engaging piece 60 is inserted into the locking groove 51.

In the third embodiment having such a configuration, when the engagement piece 60 is fitted and engaged between the one protrusion 52 of the locking groove 51 and the groove end wall surface, the introduction groove 59 is completely fitted with the fitting groove 50. The fitting protrusion 4 can be put in and taken out of the fitting groove 50 and the inner container 16 can be put in and taken out of the outer container 46 (FIG. 8A).

Further, the ring body 56 is pinched and rotated to fit and engage the engagement piece 60 between the other projection 53 and the groove end wall surface, so that the inward flange 57 closes the upper surface of the fitting groove 50. The inner container 16 is internally fixed to the outer container 46 by fixing the engaging projection 4 in the fitting groove 50 (FIG. 8B).

That is, the inner container 16 can be exchanged or internally fixed to the outer container 46 by fixing the coupling member 55 at two positions in the circumferential direction, and the outlet port 14 can be opened and closed by a screw. Even if there is, the inner container 16 is not rotated together.

In the case where the inner container 16 is held in the outer container 46 by the coupling member 55 as in the third embodiment, the cover body shown in the second embodiment can be used to open and close the outlet. Of course. Further, the cover flange 6 of the lid body 1 is provided so as to hide the engaging grooves 25, 42 and the fitting groove 50 so as not to impair the external appearance, and may be omitted in practical use. Further, two engaging protrusions 4, two engaging grooves 25 and 42, and two engaging grooves 50 are provided, but the number is not limited as long as the inner container 16 can be easily put in and taken out from the outer containers 21 and 46 and can be stably fixed.

Although the lids 1 and 31 are connected to the inner container 16 by screw fitting in each of the above-described embodiments, they may be connected by undercutting forcible fitting. Needless to say, the structure may be such that they are fitted and mounted.
