Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to a container equipped with an alignment mechanism, and more specifically, a planar polygonal lid body is screwed onto a planar polygonal container body. The present invention relates to a container equipped with a mechanism in which the vertical wall of the lid and the vertical wall of the container body are aligned on the same vertical plane in the final position.

《Prior art》 Conventionally, this type of cosmetic container was developed in 1972.
As shown in Publication No. 98647, a guide groove is provided on the outer periphery of the neck of the container body, and a guide element that can fit into this guide groove is provided on the inner surface of the lid body, and in the final process of positioning, the guide element is inserted into the inner part of the guide groove. One is configured so that the alignment is completed by reaching the end and being locked there, and the other is a structure in which the alignment is completed by reaching the end and being locked there, or a groove that protrudes outward from the lower end of the neck of the container body as shown in Japanese Patent Application Laid-Open No. 57-28764. A second stopper piece is provided at the lower end of the inner peripheral wall of the lid body, and the second stopper piece is engaged with the first stopper piece in the final process of screwing the lid body onto the neck of the container body. There are known devices that are configured so that the alignment is completed when the tool is stopped.

《Problems to be solved by the invention》 However, containers with the above structure require strict dimensional accuracy during molding in order to accurately align the lid with the container body, and long-term use also causes problems such as guides and If the stopper piece is deformed or worn out, correct positioning cannot be achieved.

In addition, at the end of the alignment, the guide provided on the lid body is engaged with the inner end of the guide groove on the neck of the container body, or the second stopper piece of the lid body is engaged with the first stopper piece provided on the neck of the container body. The structure is such that the stopper piece abuts against the lid and the lid cannot be further rotated and tightened, making it difficult to judge when alignment is complete.

Furthermore, when the alignment is complete, the lid is only screwed onto the neck of the container body, and there is no force acting on the lid to prevent it from rotating in the opposite direction, so external forces are not applied. There is a risk that the lid may come loose inadvertently.

This invention was made in view of the above problems,
The purpose of this is that strict dimensional accuracy for alignment is not required, alignment can be performed accurately even after long-term use, and the completion of alignment can be intuitively recognized, and once alignment is completed, The object of the present invention is to provide a container equipped with a positioning mechanism that prevents the lid from becoming unintentionally loosened.

<<Means for Solving the Problems>> In order to achieve the above object, the present invention provides a container body having a thread formed in the neck projecting upward from the center of the shoulder on the upper surface of the body having a planar polygonal shape. a container with a lid, comprising: an inner lid having a screw cylinder in the center that is screwed onto the neck to seal a spout hole formed in the neck; and an outer lid having a planar polygonal shape that encloses the inner lid. A pair of recesses with raised edges are formed in the shoulders of the container body, and portal-shaped elastic legs are arranged in the vertical direction so as to straddle the spiral cylinder of the inner cylinder. At the same time, the lower end thereof protrudes downward from the inner cylinder, and in the final step of rotating the outer cover and the inner cover engaged thereto to screw the threaded cylinder onto the neck, the gate-shaped The outer lid is fitted into a predetermined position on the container body by fitting the lower ends of the legs into the recesses over the raised edges.

《Operation》 When the outer lid of a container equipped with the positioning mechanism configured as described above is rotated and the inner lid is screwed onto the neck of the container body, the gap between the inner lid and the outer lid is formed at the final stage. The lower end of the portal leg disposed on the container body passes over the raised edge of the container body shoulder and fits into the recess, and the lid is aligned with the predetermined position of the container, completing the alignment. .

<<Embodiments>> Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

The figure shows an example in which a lid body 2 having the same planar shape is screwed onto a container main body 1 having a rectangular planar shape for alignment. The upper surface of the container body 1 has a shoulder 3 which is a gently sloped surface, and a neck 4 is integrally formed to protrude upward from the center of the shoulder. The upper end surface of the neck portion 4 serves as a spout 5 for dispensing the contents, and a thread 6 is provided around the outer periphery of the neck portion 4, and a tapered inclined edge 7 is provided on the upper surface of the shoulder portion 3 adjacent to the neck portion 4.
Two recesses 8 are provided at symmetrical positions with respect to the axis of the neck portion 4. The joint between the hanging wall defining the body 9 of the container body 1 and the gently sloped surface of the shoulder 3 is formed as a relatively steep slope.

The lid body 2 includes an inner lid 10, an outer lid 11, and a gate-shaped elastic leg body 1.
2 and a sealing gasket 13. The inner lid 10 has a cylindrical spiral tube 1 in its center.
4, and a thread 15 formed on the inner circumferential surface of this threaded cylinder 14 is formed so as to be able to be threadedly engaged with a thread 6 on the neck 4 of the container body 1. An annular plate 16 is integrally formed on the upper part of the screw tube 14 and protrudes inward in the circumferential direction, and has a small hole 1 whose inner diameter is reduced to the inside diameter of the screw tube 14.
It forms 7. The lower part of the screw tube 14 is surrounded by a vertical wall section 18 that is rectangular in plan and has a short vertical length, and the screw tube 14 and the vertical wall section 18 are integrally connected at their upper ends by a horizontal wall section 19. are connected in series. A horizontally elongated protrusion 20-20 is integrally provided on the outer side of one opposing wall surface of the vertical wall portion 19. A pair of concave grooves 21-2 are formed on the upper end surface of the screw tube 14 and extend in the diagonal direction of the inner cover 10, which is rectangular on one side.
1 are formed, and a pair of through holes 22-22 are bored in the horizontal wall portion 19 below these grooves 21-21. The upper end concave groove 21-2 of this screw cylinder 14
1 is fitted with the central flat part 23 of the gate-shaped elastic leg 12, and at this time, the lower end 24-24 of the leg 12 is made to protrude downward from the through hole 22-22 of the horizontal wall 19. It's getting old. The upper end corners of the elastic legs 12 are raised in a chevron shape so that the legs 12 have elasticity in the vertical direction, and the lower ends 2
