Description

[Detailed Description of the Invention] The present invention relates to a container equipped with an alignment mechanism, and more specifically, a first stopper piece is provided protrudingly from the neck or shoulder of a planar polygonal container body,
A lid formed in a planar polygonal shape and having a second stopper piece projecting thereon is screwed onto this neck, and the vertical surfaces of the container body and the lid are on the same plane at the contact position of both stopper pieces. This relates to containers that are aligned in this way.

The conventional container positioning mechanism was developed in the 1970s.
132459 is publicly known. This known device consists of a container, a cap, and a sliding member. The container is provided with a protrusion extending from the mouth and neck to the shoulder, and the sliding member can be moved up and down into the cap via an elastic piece. The lower end of the sliding member has a recess into which the protrusion can fit. Then, when the cap is tightened, the lower end surface of the peripheral wall of the sliding member hits the protrusion of the container, and the sliding member slides upward against the elastic piece and rides on the protrusion, and then the recess of the sliding member. At the position where the protrusion and the protrusion match, the elastic piece engages them and positions them.

However, in the conventional alignment mechanism as described above, if the circumferential dimensions of the protrusion of the container and the recess of the sliding member do not match accurately, the cap will wobble against the container after alignment, and the alignment will be difficult. If the end protrusion of the protrusion on which the recess of the sliding member rests is not accurate when loosening the cap later, it will be difficult to rotate the cap in the opening direction. Therefore, strict dimensional accuracy is required when molding the protrusion and recess. Not only is this required, but there is also a problem in that while the protrusion and the recess are repeatedly engaged and disengaged, the corners of the protrusion and the recess gradually wear out and the fit becomes loose.

The present invention was developed in view of the above-mentioned conventional problems, and its purpose is to provide a simple structure that prevents the lid body from loosening once it is aligned, and to provide an alignment mechanism that does not require strict dimensional accuracy. Please provide a container with the contents.

The container main body of the present invention has a thread formed in the neck projecting upward from the center of the shoulder on the upper surface of the flat polygonal body, and a first thread in the neck or shoulder.
A protruding stopper piece is provided. Further, the lid of the present invention has a screw tube in the center that is screwed onto the neck portion to seal the spout hole formed in the neck portion, and an inner wall having a planar polygonal hanging wall on the outer periphery of the screw tube. It consists of a lid and an outer lid that tightly encloses the inner lid, and either the inner lid or the outer lid is provided with a second stopper piece that engages with the first stopper piece. The joint corner between the body and the shoulder of the container body is formed as an inclined surface, and the lower end surface of the outer cover is formed as an inclined end surface corresponding to the inclined surface, and the inner cover and the outer cover are formed as an inclined surface. The outer cover is movable up and down with respect to the inner cover by loosely fitting the outer cover into the inner cover, and an elastic material is disposed between the end faces of the inner cover and the outer cover to move the outer cover into the inner cover. The slope formed at the lower end side of the outer cover is always biased downward against the cover, and in the final process of rotating and tightening the outer cover and the inner cover against the neck of the container body. When the end surface crosses over the corner of the upwardly inclined surface of the container body, the outer lid moves upwardly against the inner lid against the elastic material, and at the position where the end face has completely climbed over the corner, the outer lid moves upwardly against the inner lid. The first stopper piece and the second stopper piece are elastically lowered relative to the inner cover, each side of the outer cover is located on the same vertical plane as the side of the container body directly below it, and the first stopper piece and the second stopper piece The two pieces are in contact with each other.

As mentioned above, as soon as the inclined end surface formed on the lower end side of the outer cover completely overcomes the corner of the upper inclined surface of the container body, the outer cover elastically descends and the above inclined end surface of the outer cover moves over the upper inclined surface of the container body. Since it is crimped by surface contact with the above-mentioned upwardly inclined surface of , the position will not shift after alignment. The contact between the first stopper piece and the second stopper piece is such that the lid body is against the container body.
Since the purpose is to prevent further rotation, strict dimensional accuracy is not required for the shape. In addition, in the final stage of the above alignment,
When the outer lid elastically descends, its lower end inclined surface makes a "snap" sound and comes into close contact with the upper inclined surface of the container body, completing the alignment, so the completion of alignment can also be known by the sound. I can do it.

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 4 serves as a spout 5 for pouring the contents, and a thread 6 is provided around the outer periphery of the neck 4, and a first stopper piece 7- is provided at the joint between the neck 4 and the shoulder 3. 7 are provided in two protruding positions at symmetrical positions with respect to the axis of the neck portion 4. The joint between the hanging wall defining the body 8 of the container body 1 and the gently sloped surface of the shoulder 3 is formed as a relatively steep slope 9.

The lid body 2 is formed by combining an inner lid 10, an outer lid 11, a top plate 12, and a sealing gasket 13. The inner lid 10 has a cylindrical screw tube 14 in its center, and a screw thread 1 formed on the inner peripheral surface of the screw tube 14.
5 is formed so as to be able to be screwed into the thread 6 of the neck 4 of the container body 1. Further, two second stopper pieces 16-16 are protruded from the inner lower part of the screw tube 14 at symmetrical positions with respect to its axis. The second stopper piece 16-16 is the first stopper piece 7-7.
It is coming into contact with the An annular plate 17 is integrally formed at the upper part of the screw tube 14 and protrudes inward in the circumferential direction to define a small hole 18 with the inner diameter of the screw tube 14 reduced. The screw tube 14 is surrounded by a vertical wall section 19 having a rectangular planar shape, and the lower end portions of the screw tube 14 and the vertical wall section 19 are integrally connected by a horizontal wall section 20 . A horizontally long protrusion 21-21 is provided on the outside of one of the opposing walls of the vertical wall portion 19.
are integrally protruded, and bow pieces 22-22 are formed at the lower end of each surface of the vertical wall portion 19 to protrude downward. Both ends of each bow piece 22 are integrated with the corners of the vertical wall part 19, and the center part is separated from the lower end surface of the vertical wall part 19, so that the bow piece 22 has elasticity in the vertical direction. have.

A small hole 18 formed in the screw tube 14 of the inner lid 10 is provided with a sealing gasket 1 made of rubber, soft plastic, etc. and formed with a slightly larger diameter than the small hole 18.
The head 23 of No. 3 is forcibly inserted from below. As shown in FIG. 2, an O-ring 25 is included in the periphery of the sealing disk portion 24 of the sealing gasket 13, and this O-ring 25 is inserted between the lower surface of the annular plate 17 of the screw tube 14 and the disk portion 24. It is configured so that it can be compressed.

The inner cover 10 is assembled by fitting the outer cover 11 shown in FIG. A groove 26-26 is formed, and when the inner cover 10 is fitted to the outer cover 11, the protrusion 21- of the inner cover is formed.
21 fits into this groove 26-26. The vertical width l ₁ of each groove 26 is the vertical width l ₂ of the protrusion 21.
The outer cover 11 is formed to be sufficiently larger than the inner cover 10, so that the outer cover 11 can move vertically inside the inner cover 10. An annular flange 27 that protrudes slightly inward is formed on the lower edge of the outer lid 11, and the convex strip 21-21 of the inner lid 10 is connected to the groove 26- of the outer lid 11.
26 and when assembled, the bow piece 22-22 formed protruding from the lower end of the inner cover 10 is connected to the flange 2 of the outer cover 11.
7, and the elasticity of this bow piece 22-22 urges the outer lid 11 downward with respect to the inner lid 10, and the protrusion 21-21 is in contact with the upper end step 26a of the groove 26-26. -26a is in constant contact.

After fitting and assembling the inner cover 10 to the outer cover 11 as described above, the top plate 12 is adhered to the upper part of the outer cover 11, thereby completing the cover body 2.

In order to seal the spout 5 of the container body 1 using the lid 2 configured as described above, the screw tube 1 of the lid 2 is
4 from above the neck 4 of the container body 1 and rotated, the thread 15 formed on the inner periphery of the barrel 14 screws into the thread 6 formed on the outer periphery of the neck 4, and the lid is closed. Body 2 gradually descends. In this way, the lid body 2 is screwed together, and at the stage before the final alignment by 1/4 turn, the lower end surface of the outer lid 11 is connected to the shoulder part 3 of the container body 1 and the body part 8. When the lid 2 is further rotated from this stage, the lower end surface of the outer lid 11 comes into contact with the corner of the slope 9 (a corner formed in a rectangular plane). ). At this time, since the outer cover 11 can move upward by l ₁ to _{l 2} against the inner cover 12 against the elastic bow pieces 22-22, the outer cover 11 is elastically moved upward. While moving, it runs onto the above corner. Next, the lid 2 is further rotated, and the first stopper piece 7 of the container body 1 is moved to the second stopper piece 1 of the lid 2.
6, that is, when the outer lid 11 finishes climbing over the corner, each vertical wall of the lid 2 and each vertical wall of the container body are located on the same vertical plane, and at the same time, The outer cover 11 is pushed down by the action of the elastic bow piece 22 of the inner cover 10, and the lower end surface of the outer cover 11 "snaps" against the inclined surface 9 of the container body 1.
They make a sound when they come into contact and the alignment is complete. At this time, the spout of the neck 4 of the container body 1 is sealed by compressing the sealing gasket 13.
After being aligned in this way, the lower end surface of the lid body 2 pushes up the corner of the inclined surface 9 of the container body 1 against the elastic bow pieces 22-22 and rotates in the opposite direction to the above case. The lid will not come loose unless

In the above embodiment of the present invention, elastic bow pieces 22-22 are integrally provided at the lower end of the inner cover 10 in order to enable the outer cover 11 to move elastically up and down with respect to the inner cover 10. However, in place of the elastic bow piece 22-22, in the second embodiment of the present invention, an O-ring 22a may be provided as shown in FIG. This fourth
The other parts of the container structure according to the second embodiment of the present invention shown in the figures are the same as those of the first embodiment, so the same parts are given the same reference numerals and the explanation will be omitted.

As described above, in the container equipped with the positioning mechanism of the present invention, the outer lid elastically rises relative to the inner lid at the final stage of alignment, and when the alignment is completed, the outer lid elastically lowers. Therefore, the alignment can be tactually detected at the fingertips, and since the outer cover usually makes a "snap" sound when lowered, it is also possible to recognize the completion of the alignment audibly. Moreover, once the positioning is completed, since the elastic member presses the inclined end surface of the lower edge of the outer lid against the upper inclined surface of the container body, there is no fear that the lid body will come loose inadvertently.

Furthermore, since the first stopper piece and the second stopper piece are used to prevent the lid from further rotating with respect to the container body, strict dimensional accuracy is required in their shape. There isn't.
