Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a composite container.
[0002]
[Prior art]
There is known a pump container including a container main body with the mouth and neck raised from the trunk and a pump attached and fixed to the container main body with a mounting cylinder fitted to the outer periphery of the mouth and neck.
[0003]
These pump containers are generally discarded as they are after the stored liquid is used up, and new pump containers are used. However, with the recent deterioration of waste disposal circumstances, it has been desired to reduce the amount and volume of waste as much as possible, and various proposals have been made accordingly.
[0004]
The applicant has already proposed a container with a refillable pump in order to answer such a demand (Japanese Patent Laid-Open No. 10-323586). The container is provided with a container body in which a suction pipe is suspended from the neck and neck portion through a pump connecting cylinder portion in the body portion, and the pump is detachably mounted on the mouth and neck portion of the container body, and the lower end of the pump The suction port is detachably fitted to the pump connecting cylinder part, and the exterior cylinder is detachably fitted to the outside of the body part of the container main body.
[0005]
The pump container can be easily replaced with a refill container body that has been pre-filled with the contents of the container body, i.e., the pump and outer cylinder, which occupy most of the container price, remain. It is sufficient to replace only the simple and low-priced refill container body, and therefore, it is possible to make a luxurious and attractive high-grade one that repeatedly uses the pump and the outer tube, and to eliminate the economic loss of disposables. Even if the strength and hardness are insufficient with a simple container body, not only can it be reinforced with the exterior, but the container body can be protected from external forces with the exterior cylinder.
[0006]
Further, there is no hassle for filling the contents each time by the consumer, and it is possible to reduce the time and effort. The filling does not cause the contents to leak and the surroundings to become dirty, and the contents to be lost.
[0007]
[Problems to be solved by the invention]
However, because of their structure, the container body must be composed of at least two members, and accordingly, there is a complication in molding, and pumps that can be used tend to be limited. There was room for.
[0008]
The present invention has been made in view of the above points. The container body can be formed with a single member, the number of pumps that can be used is limited, and when the contents of the container body disappear as described above, the contents are filled in advance. A composite container that can be easily exchanged with a refill container body that has been used, and that can also exhibit the effects of the conventional container body described above, such as being able to replace only a low-priced simple refill container body. This is a proposal.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0018]
The composite container 1 of the present invention includes a case body 2 and a container body 3.
[0019]
The case body 2 is a non-replacement product that supports the container body 3 to be replaced after using the stored liquid, and has a cylindrical shape with an upper end opened. Since it is a non-replacement product, it is preferable to select the thickness, material, etc. with emphasis on durability, and as the material, synthetic resin, metal, or a combination thereof can be preferably used. Specifically, various forms such as those having a multilayer structure in which the base surface of the synthetic resin base is covered with a metal layer and those formed entirely of metal can be adopted. Moreover, it is good to give a decoration layer to an outer surface by appropriate methods, such as printing and uneven | corrugated formation. In the illustrated example, the bottom wall 5 is extended from the lower end edge of the cylindrical peripheral wall 4. In addition, you may provide a through-hole in this bottom wall 5 so that the container main body 3 can be attached or detached easily.
[0020]
The container body 3 is made of a synthetic resin formed by a molding method such as blow molding. The container body 3 contains liquid therein, and the stored liquid is discarded and replaced after use. The mouth-and-neck part 8 is erected through 7. The body portion 6 is fitted in the case body 2, and the upper portion of the outer surface is engaged with the upper portion of the inner surface of the case body peripheral wall 4 so as to be prevented from coming out and is detachably mounted. As such an engaging means, as shown in the illustrated example, a thread 9 may be provided at predetermined positions on the inner periphery of the case body 2 and the outer periphery of the container body 3 so as to be screwed and locked. 3, a bowl-shaped fitting recess 10 having an upper end opened at a predetermined position on the inner surface of the case body 2, and a protrusion 11 that fits into the fitting recess 10 at a predetermined position on the outer periphery of the container body 6. A projecting configuration may be used.
[0021]
Moreover, you may comprise so that the diameter-expanded part which expanded the diameter of the trunk | drum 6 of the container main body 3 may be exposed on the case body 2 as the finger-hook part 12. FIG. By providing this finger hook 12, the container body 3 can be easily detached from the case body 2.
[0022]
Further, since the container body 3 is for replacement that is discarded after the stored liquid is used, in the present invention, the portion other than the portion extending from the engaging means attaching portion of the trunk portion 6 to the mouth neck portion 8 is formed thin. The engaging means-attached portion has a thickness necessary for firmly engaging the case body 2, and the upper finger-holding portion 12, shoulder portion 7 and mouth-and-neck portion 8 are exposed portions. Since it is a part which is not protected by the case body 2, it forms in the thickness provided with some rigidity. The other portions are preferably formed as thin as possible to reduce the cost of the container body 3. Although the specific degree of thinness of the thin part 6a is considered as a standard for the amount of resin per volume of 500 ml being about 5 to 40 g, it is not limited to this.
[0023]
Moreover, it is good to provide the folding line 13 for folding in the trunk | drum 6 of the container main body 3. FIG. The folding line 13 is formed by arranging a groove-shaped or ridge-shaped line formed in the body portion 6 so that the body portion can be folded small. By providing this, the folding line 13 can be easily reduced at the time of disposal. It is configured so that it can be treated as waste with a small volume. The specific arrangement form of the folding line 13 can be variously selected as long as the container body 3 can be folded small. For example, as shown in the drawing, a pair of vertically long lines formed on the front and back of the body portion 6 are left behind. 13a and a pair of inclined lines 13b are formed obliquely downward from directly below each of the vertically long lines 13a, and each portion is bent in a predetermined direction so that it can be easily folded into a small volume as shown in FIG.
[0024]
Moreover, you may provide the stopper of the engaging means engaged in order to prevent the said withdrawal. Although the above-described screwing or fitting into the fitting recess can sufficiently prevent the upward pulling out as the engaging means, the stopper can be provided more reliably to prevent the pulling out.
[0025]
FIG. 6 employs screw engagement between the case body peripheral wall 4 inner surface upper portion and the body portion 6 outer surface upper portion as the engaging means, and the upper end portion of the body portion 6 is expanded as a stopper to be exposed on the case body. A stopper comprising a recess 20 provided at the lower end of the outer surface of the finger hook 12 and a protrusion 21 that is engaged with the recess 20 when the container body is screwed to the case body and is erected on the upper surface of the case body peripheral wall 4 is employed. ing. The recess 20 can preferably be recessed in an arcuate shape, and correspondingly, the protrusion 21 can preferably be employed in which at least the inside protrudes in an arcuate shape.
[0026]
FIG. 7 shows that the engaging means is provided at a predetermined position on the outer periphery of the container body 6 and a fitting concave portion 10 having a bowl-shaped upper surface opening provided at a predetermined position on the inner surface of the case body peripheral wall 4. The lower surface of the finger hooking portion 12 that employs an engaging means comprising a protrusion 11 that is pushed in from above and is fitted by turning, and has an upper end portion of the body portion 6 that has been enlarged in diameter and exposed on the case body as a stopper. And a stopper comprising a recess 22 provided on the upper surface of the case body peripheral wall 4 and a projection 23 fitted into the recess 22 is employed. In this embodiment, the protrusion 23 is formed from the lower surface of the finger-hanging portion 12 and the concave portion 22 is formed on the upper surface of the case body peripheral wall 4.
[0027]
FIG. 8 shows a fitting recess 10 having a bowl-shaped upper opening provided at a predetermined position on the inner surface of the case body peripheral wall 4 and a predetermined position on the outer periphery of the container body 6 as the engaging means. Employs engaging means consisting of a protrusion 11 that is pushed in from the top and is turned and fitted, and serves as a stopper that protrudes from the lateral groove portion of the fitting recess 10 and is pressed against the fitted protrusion 11 A protrusion 24 is provided. The press contact protrusion 24 may be provided on the lower surface of the lateral groove.
[0028]
The composite container 1 configured as described above can be used with a normal cap or a pump. 1 to 3 show an example in which a pump 14 is mounted. The pump 14 is detachably mounted on and fixed to the composite container 1 by a mounting cylinder 15 that is detachably fitted to the outer periphery of the mouth neck portion 8. The lower part of the cylinder 16 fixed by the mounting cylinder 15 is suspended from the upper part in the container body, and a suction pipe 17 is suspended from the lower end of the cylinder 16. Further, an ejection head 18 is provided that protrudes upward and downward from the upper end of the cylinder 16 so as to be urged upward. A known pump mechanism is provided which is constructed so that the liquid in the container body is sucked up by the vertical movement of the head and ejected from the ejection port (not shown) of the head.
[0029]
For the composite container 1 equipped with the pump in this way, the container body 3 is removed from the case body 2 after the stored liquid is used up, for example. At this time, the container main body 3 can be rotated by the finger hook 12 to be screwed off. Next, after removing the pump 14 from the container body 3 and mounting the pump 14 on a replacement composite container (not shown), the case body 2 can be mounted again to replace the container body 3. The container body 3 from which the pump 14 has been removed can be folded in a predetermined direction at the folding line 13 portion. In the figure, 19 indicates an overcap.
[0030]
【The invention's effect】
As described above, since the composite container of the present invention has the above-described configuration, the container main body 3 can be formed as a single member, the number of pumps that can be used is limited, and only the container main body 3 needs to be replaced. It is economical, and when it is used as a pump container with a pump attached, the pump 14 and the case body 2 can be used repeatedly with luxury and good-looking luxury, and the container body 3 is insufficient in strength. Even so, the case body 2 can not only reinforce the container body 3 but also the case body 2 can protect the container body 3 from external forces.
[0031]
Further, in the case where the body portion 3 of the container body 3 is thinly formed except for the portion extending from the engaging means attaching portion to the mouth neck portion 8, when the container body 3 is discarded, the amount is further increased. Moreover, since the thin portion is protected in the case body 2 at the time of use, there is no inconvenience in use.
[0032]
Further, in the case where the enlarged diameter portion obtained by expanding the diameter of the upper end portion of the body portion 6 of the container body 3 is exposed as the finger hook portion 12 on the case body, the removal of the container body 3 from the case body 2 is extremely difficult. It becomes easy.
[0033]
Further, in the case where the body portion of the container body 3 has a folding line 13, the container body removed at the time of disposal after use can be easily folded into a small volume and discarded as a small volume waste. be able to.
[0034]
In addition, in the case where a stopper for engaging means to be engaged is provided so as to prevent slipping or the like, which is represented by engagement between the hook-shaped fitting recess and the protrusion, etc., loosening of the engaging means It is possible to prevent the container body from coming out of the case body more reliably.
