Description

[Detailed Description of the Invention] The present invention relates to a one-touch opening type container such as a compact.

Conventionally, containers such as compacts of this type have a locking means such as a hook protruding from the opening edge of the container and the lid, and the container and the lid are closed by engagement of the hook. However, the opening requires a strong force to disengage the engagement and is easily damaged. Therefore, in recent years, an opening operation member is slidably attached to the opening edge of the container and the lid, and the engagement between the two bodies is released by separating the container and the lid by pushing the opening operation member. A structure that allows the opening to be opened has been proposed, but
All of them have drawbacks such as relatively complicated structures such as slide holes that are difficult to mold and cut out, and high manufacturing costs.

In view of the above, the present invention provides a container such as a compact, in which a container and a lid are connected by a hinge so that they can be opened and closed, and locking means that can be engaged with each other when closed are provided at appropriate positions on the opening edges of both. It was devised so that it can be opened reliably with a simple one-touch operation, and the structure is simple so that it can be manufactured and provided easily and inexpensively. An engaging protrusion is provided at the center of both sides of the notched recess, and an opening operating member having an approximately U-shaped cross section consisting of an upper plate and inner and outer plates is provided in the notched recess, and the engaging protrusion is inserted between the inner and outer plates. At the same time, the upper plate is fitted with locking claws hanging slightly inward from both ends of the upper plate so that they can be slid outwardly and backwards by engaging both engaging protrusions. A convex portion is provided on the upper surface of the member and the lower surface of the opening edge of the lid body opposite thereto, so that the opening operation member can press and slide into contact with each other by the pushing and retracting action of the opening operation member. This is characterized in that the locking means is disengaged.

Next, embodiments of the present invention will be described based on the drawings.
10 is a container such as a compact, and 20 is a lid, both of which are connected to each other by a screw 1 so that they can be opened and closed.
and 21 are provided with locking means 12 and 22 that can engage with each other when closed, so that the closed state can be maintained.

A cutout recess 13 that opens upward and outward and has an L-shape at the bottom and the inner surface is provided at the opening edge 11 of the container 10 on the side facing the screw 1. Narrow plate-shaped engagement protrusions 14, 14 are provided at approximately the center of both left and right sides so as to protrude parallel to the bottom surface and face each other at a required interval. 3
Reference numeral 0 denotes an opening operation member having a substantially U-shaped cross section, consisting of an upper plate 31 and inner and outer plates 32 and 33 hanging from its inner and outer edges, and has an opening operating member on the lower surface of the upper plate 31 located slightly inward at both ends thereof. has claws 34, 34 on the outside of the lower end.
The latching claw pieces 35, 35 having latching claw pieces 35, 35 are vertically provided at a predetermined interval. This opening operation member 30 is fitted from above into the notched recess 13 so that both engaging protrusions 14, 14 are fitted between the inner and outer plates 32, 33, and the latch claw pieces 35, 35 Both engaging protrusions 1 are made using the elasticity of materials such as synthetic resin.
The engaging protrusion 14 is fitted between 4 and 14.
The inner and outer plates 32 and 33 are hooked to the ends of the engaging protrusion 1 to prevent it from being pulled out upwardly, and the inner and outer plates 32 and 33 are
4 and 14 so as to be slidable inwardly and retractably. In order to slide forward and backward, the gap between the inner and outer plates 32 and 33 of the opening operation member 30 is slightly larger than the width of the engagement protrusions 14 and 14, and there is a slight gap between the inner plate 32 and the inner surface of the notch recess 13. is set to hold. The upper surface of the upper plate 31 of the opening operating member 30 and the lower surface of the opening edge 21 of the lid body 20 opposite thereto are normally arranged in alternating positions, and are pushed in and out of the opening operating member 30 from the side. Convex portions 36 and 26 that can be pressed and slid into contact with each other are provided near the top, and the container 10 and the lid body 20 are brought into contact with each other by pressing the convex portions 36 and 26 together.
The locking means 12, 22 can be disengaged from the locking means 12, 22 by slightly separating them.

The above-mentioned convex portions 36, 26 may have any shape, such as a semicircular cross section or a triangular shape, as long as the pressing and sliding contact is possible, but the pressing and sliding contact of at least one of the convex portions It is more suitable for the pressing and sliding contact to form the side surface as a relatively gently sloped slope, and in the embodiment shown in FIGS. 1 to 4, the opening operating member 3
In the case where a slope 37 is formed on the convex part 36 on the 0 side, in the embodiment shown in FIG.
Further, in the embodiment shown in FIG.
7 is formed.

In addition, a locking means 12 between the container 10 and the lid 20,
22, in the embodiment shown in FIGS. 1 to 4, a protrusion serving as the locking means 12 is provided on the back surface of the notch recess 13, and the opening edge 21 of the lid body 20 is provided with a protrusion that serves as the locking means 12. 6 shows a case in which a hook is provided vertically as a locking means 22 that can be inserted between the notched recess 1 and the protruding strip 1.
A case is shown in which a convex portion serving as a locking means 12 is provided on the inner surface of the rear wall of the lid 20, and a hook serving as the locking means 22 that can be locked to the convex portion is provided vertically on the lid body 20.

The present invention is constructed as described above, and in its use, when the container 10 and the lid 20 are closed, the opening operation member 30 is in the advanced position and the locking means 12 and 22 of both bodies are in the engaged state. Retained. When the container 10 and the lid 20 are disengaged from each other by the locking means 12, 22 and opened, the opening operation member 30, which is provided so as to be able to move forward and backward, is pushed in and out with a fingertip. As the operating member 30 is pushed in and out, the convex portion 36 on the upper surface of the operating member 30 moves toward the lid 2.
The lid body 20 is pushed up so as to be slightly separated from the container body 10 while pressing and sliding against the convex portion 26 on the zero side, thereby allowing the locking means 12 and 22 to be disengaged from each other. The opening can be reliably opened by a very simple one-touch operation of pushing the opening operation member 30.

Particularly in the case of the present invention, the opening operation member 30 is
1 and the inner and outer plates 32 and 33 have a substantially U-shaped cross section, and the inner and outer plates 32 and 3 have engaging protrusions 14 and 14 protruding from substantially the center of both sides of the cutout recess 13.
3, and the top plate 3.
Since the latch claw pieces 35, 35 provided vertically on the lower surface of 1 are hooked to the engaging protrusions 14, 14, the inner plate 32 abuts and engages with the engaging protrusions 14, 14, and the outer plate It comes out in the direction, but the latch claw pieces 35, 3
5 and the engaging protrusions 14, 14 prevent them from coming off upward, and the attached state can be maintained without fear of detachment. Moreover, the opening operation member 3
0 has a substantially U-shaped cross section, the engaging protrusion, the locking claw piece, etc. are covered by the opening operation member itself and are not visible from the outside, giving a good appearance. Damage to parts such as mating protrusions can be prevented. Of course, the opening operation member 30 includes the inner and outer plates 32,
33 can slide forward and backward within the cutout recess 13 within the range in which it contacts the engagement protrusions 14, 14, and there is no problem with the opening operation. Furthermore, since the present invention does not require a through hole or the like that is difficult to cut out due to the mounting structure of the opening operation member, it has the advantage that the container can be easily molded and manufactured.
