Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a support for a thin-walled container that gives shape retention by imparting rigidity to the thin-walled container.
[0002]
[Prior art]
When thinning the container from the viewpoint of material reduction or the like, the rigidity of the container itself becomes a problem. For example, Japanese Patent Application Laid-Open Nos. 6-242586 and 7-22968 address this problem by fitting a paper outer cylinder around the outer surface of the body of the container body or winding paper.
[0003]
[Problems to be solved by the invention]
In the former of the above-mentioned known example, there is a risk that the outer cylinder fitted to the outer surface of the body part of the container body may come out downward. On the other hand, in the case where annular protrusions for preventing extraction are formed at both upper and lower ends of the body part, Although it does not exist, in order to load the paper, it is troublesome to wind the paper around the body and bond the both ends thereof.
In the latter of the above-mentioned known examples, the bottle has to be provided with two recesses and the lower end of the bottle must be tapered, so that the bottle shape must be complicated, and the flap is in the recess to remove the paper tube. Since the paper tube must be pulled out in the engaged state, it is not easy to remove the paper tube.
In addition, in any of the above cases, since the durability is insufficient, the number of times of use is limited.
[0004]
An object of the present invention is to provide a thin-walled container support that can be easily attached to and detached from a thin-walled container and can withstand repeated reuse.
[0005]
[Means for Solving the Problems]
As a first means, loosely fit the container main body 2 to the peripheral wall of the fitting cylinder 11 to which the lower portion of the main body of the thin container 1 that erects the mouth neck 4 from the upper end of the body 2 via the shoulder 3 is fitted. The lower end portions of both leg portions 13 of the U-shaped or U-shaped support plate 12 are pivotally supported , and the upper end portion of the peripheral wall of the fitting cylinder 11 and the leg portion 13 above the pivot support portions of the both leg portions 13. A protrusion 15 is formed on one side of the portion and a recess 16 is formed on the other. The protrusion 15 is detachably engaged with the recess, and is further attached to and detached from the container body neck 4 on the support plate 12. It is characterized in that a recess 14 for fitting to be freely fitted is formed.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of a thin-walled container support according to the present invention will be described with reference to the drawings.
1 is a thin-walled container made of synthetic resin, and the mouth and neck part 4 is erected from the upper end of the trunk part 2 through the shoulder part 3. A mounting cylinder 6 of a known vertical pump having a pressing head 5 with a nozzle as shown in the figure may be screwed into the mouth and neck, or a cap may be screwed simply. In addition, the thickness of the container is a thickness obtained by setting the amount of resin used to about 5 to 40 g with respect to a volume of 500 ml, and does not have a shape retaining property that can stand by itself because it does not have rigidity.
[0007]
Reference numeral 10 denotes a synthetic resin support. The lower end portions of the leg portions 13 of the U-shaped support plate 12 are pivotally supported on the left and right outer surfaces of the fitting cylinder 11 closed at the bottom, and both leg portions are supported. A part of the left and right intermediate portions of the connecting plate portion between 13 is cut out to form a fitting recess 14. Further, the protrusion 15 is formed at the upper end portions of the left and right outer surfaces of the fitting cylinder 11, and the concave groove 16 that can be fitted to the protrusion 15 is formed in the leg portion above the shaft support portion of the both legs 13. .
[0008]
In the above description, the projection 15 is formed on the fitting cylinder 11 and the concave groove 16 is formed on the leg 13. However, the present invention is not limited to this, and the concave groove 16 is formed on the fitting cylinder 11 and the projection 15 is formed on the leg 13. It is also possible to form.
[0009]
Next, the operation of this embodiment will be described.
In order to use contents such as shampoo stored in the thin-walled container 1, the lower portion of the body portion 2 is fitted into the fitting cylinder 11, and then the legs 13 are turned by rotating the support plate 12 upward. Is fitted to the body portion 2 so that the fitting recess 14 is fitted to the mouth neck 4 portion below the mounting cylinder 6, and the protrusion 15 is fitted into the concave groove 16 simultaneously with the fitting. Therefore, the support plate 12 is prevented from being detached from the mouth / neck portion 4.
[0010]
Next, the pressing head 5 may be pressed down to eject the contents from the nozzle. When the container 1 is emptied, the support plate 12 is rotated downward, the fitting recess 14 is detached from the mouth-and-neck portion 4, and then the body portion 2 is taken out from the fitting tube 11, The support 10 can be reused repeatedly.
[0011]
【The invention's effect】
According to the present invention, since the body portion is fitted to the fitting cylinder and the mouth and neck portion is supported by the support plate, the thin-walled container having no rigidity can have shape retention.
In addition, the attachment to the container is easy to attach and detach the support to and from the thin-walled container because only the body is fitted into the fitting cylinder and the support plate is rotated.
Further, since the structure is simple, it is durable and can be reused repeatedly.

Claims (1)

A U-shape or U-shape that loosely fits to the container main body 2 to the peripheral wall of the fitting tube 11 that fits the lower portion of the main body 2 of the thin-walled container 1 that erects the neck portion 4 from the upper end of the body 2 via the shoulder 3 The lower end portions of both leg portions 13 of the support plate 12 are pivotally supported , and protrude into one of the upper end portion of the peripheral wall of the fitting cylinder 11 and the leg portion 13 portion above the shaft support portion of the both leg portions 13. A recess 15 is formed on the other side of the part 15, and the protrusion 15 is removably engaged with the recess, and further fitted on the support plate 12 so as to be detachably fitted to the container neck 4 of the container body. A thin-walled container support characterized in that a combined recess 14 is formed.
