Description

[Technical Field]

[0001] The present invention relates to a container with a lid that has a child lock function. [Background technology]

[0002] To prevent accidents caused by small children, etc., imitating the actions of adults around them, removing the lid of the container and putting the contents in their mouths, without understanding the danger of the contents contained in the container, and accidentally eating or swallowing them, there are known containers with lids that have a function on the lid that makes it difficult for small children, etc., to remove the lid, i.e., a so-called child lock mechanism (hereinafter referred to as a "CR mechanism" as appropriate) (for example, Patent Document 1). The container described in Patent Document 1 has a pair of first fitting portions provided on the front side of the lid body and a second fitting portion provided on the side, and in order to open the opening, it is necessary to release the fitting of both the first fitting portion and the second fitting portion, thereby providing a child lock function. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-95157 Summary of the Invention [Problem to be solved by the invention]

[0004] However, with the container described in Patent Document 1, when opening the opening, it is necessary to perform the release operation at least twice at both the first fitting portion on the front side and the second fitting portion on the side side, which is cumbersome for users (adults, etc.) who fully understand the characteristics of the contents to be stored.

[0005] The present invention aims to solve the problems of the conventional technology described above by creating a lidded container equipped with a child lock mechanism that makes it difficult for young children to open but allows adults to open and close it with a simple operation. [Means for solving the problem]

[0006] Among the means for solving the above problems, the first means of the present invention is: A lidded container having a container body for accommodating contents and a lid member provided so as to be attachable to a flange provided at an opening of the container body, the lid member includes a lower frame portion assembled to the flange, an upper frame portion fitted to the lower frame portion, and a lid body having a lid plate and closing the opening, and also includes a CR mechanism that allows the lid member to be opened and closed; the lower frame portion has a lower frame top wall, and lower frame inner and outer walls disposed opposite each other on the inside and outside of the lower frame top wall, and the upper frame portion is formed by an upper frame top wall, and upper frame inner and outer walls disposed opposite each other on the inside and outside of the upper frame top wall, the CR mechanism is formed with an engaging protrusion protruding radially inward from the inner surface of the upper frame outer wall, an upper locking portion protruding radially outward from the lower frame top wall and provided so as to be engageable with the engaging protrusion, a lower locking portion formed at the lower end of the lower frame outer wall and provided so as to be able to house the engaging protrusion, and a knob portion provided upright on the upper frame outer wall, The lid body can be opened by performing a first operation of pulling the knob upward, followed by a second operation of pushing the knob backward. In the first method of the present invention, a first operation must be followed by a second operation to open the lid, which prevents accidental ingestion or swallowing by small children, etc., and is a simple operation for adults, etc., making it easy to open the lid.

[0007] A second aspect of the present invention is the above-mentioned first aspect, further comprising the addition of a pair of first slits formed in the front surface of the outer wall of the upper frame. With the above means, when the second operation is performed, the upper frame front wall 26C1 located between the pair of first slits 26f can be easily elastically deformed forward, thereby improving operability when opening the lid.

[0008] A third aspect of the present invention is the above-mentioned first or second aspect, further comprising the step of forming a second slit in the shape of an elongated hole in the top wall of the upper frame. With the above means, when the second operation is performed, the width of the second slit 26h is deformed, making it possible to easily elastically deform the upper frame front wall 26C1 forward, thereby improving operability when opening the lid in the same manner as above.

[0009] Furthermore, the fourth aspect of the present invention is the first or second aspect, further comprising the addition of a hinge portion between the lower frame and the lid, which allows the lower frame and the lid to be rotatably connected to each other. With the above means, it is possible to prevent the lid from being lost, and also to open and close the opening with the lid easily and reliably.

[0010] A fifth aspect of the present invention is the above-mentioned first or second aspect, further comprising the step of forming the lower frame portion integrally with the flange. The above means makes it possible to reduce costs by reducing the number of parts. [Effects of the Invention]

[0011] In the present invention, when opening the lid, it is necessary to perform a first operation of holding the knob and pulling it upward, and a second operation of pushing the knob backwards in succession. This prevents accidental ingestion or swallowing by small children (child lock function), and the operation is simple for adults, allowing the lid to be opened easily.

[0013] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a plan view of a lidded container showing an embodiment of the present invention, Fig. 2 is a front view showing the main parts of the lidded container, Fig. 3(a) is a cross-sectional view taken along line aa in Fig. 1, and Fig. 3(b) is a cross-sectional view taken along line bb in Fig. 1. Fig. 3 shows the lidded container in a closed state. In the following description, the direction along the container axis O will be referred to as the axial direction, the up-down direction, or the height direction, the direction perpendicular to the container axis O will be referred to as the radial direction, and the direction going around the container axis O will be referred to as the circumferential direction. Furthermore, with respect to the container axis O as the reference, the side on which a CR mechanism A (described later) is provided will be referred to as the front side, and the opposite side on which a hinge portion 29 is provided will be referred to as the rear side.

[0014] The lidded container 1 shown in the embodiment of the present invention is used as a container for storing contents such as detergents in various shapes, such as a ball-shaped liquid covered with a film, or powder. Such a lidded container 1 is mainly composed of a container body 10 and a lid member 20, and these members are formed by injection molding a synthetic resin material such as polypropylene.

[0015] As shown in Fig. 2, the container body 10 is a cylindrical member with a bottom, having a peripheral wall 13 that gradually expands in diameter upward to form a space inside, and a circular bottom wall (not shown) at the lower end of the cylindrical peripheral wall 13. The container body 10 is configured to have a storage space of a predetermined capacity inside. As shown in Figs. 3(a) and 3(b), a flange 11 formed in an outer flange shape from the upper end of the peripheral wall 13 is provided in an annular shape around the upper end of the opening 12 of the container body 10, i.e., the upper end of the peripheral wall 13.

[0016] 1, the lid member 20 is formed to have an annular lower frame portion 21 that is attached to the flange 11, and a lid body 25 that entirely closes the opening 12 on the container body 10 side, and in this embodiment, the lower frame portion 21 and the lid body 25 are integrally formed with a hinge portion 29 that rotatably connects them. Note that the portion colored black in FIGS. 1 and 2 indicates the lower frame portion 21.

[0017] As shown in FIG. 1, the lower frame portion 21 is a member formed to have a generally U-shaped cross section and a circular ring shape in plan view, including a lower frame top wall 21A and lower frame inner and outer walls 21B and 21C disposed opposite each other on the inside and outside of the lower frame top wall 21A. A circular opening 21E (see FIGS. 3(a) and 3(b)) is formed inside the lower frame inner wall 21B. As shown in FIG. 3(b), engaging portions 21a are protruding from the outer surface of the lower frame outer wall 21C at multiple locations (four locations in this embodiment) in the circumferential direction. Undercut-shaped claws (not shown) are protruding from the inner surface of the lower frame outer wall 21C at multiple locations in the circumferential direction to engage the flange 11 when the lid member 20 is attached to the upper portion of the container body 10.

[0018] As shown in FIG. 1, the lid body 25 is formed with an annular upper frame portion 26 and a disk-shaped cover plate 27 connected to the inside of the upper frame portion 26. The upper frame portion 26 has an upper frame top wall 26A and an upper frame inner wall 26B and an upper frame outer wall 26C disposed opposite each other on the inside and outside of the upper frame top wall 26A, forming a generally U-shaped cross section. The cover plate 27 is connected to the upper frame inner wall 26B via a groove 28 formed around its outer edge. Furthermore, as shown in FIG. 3(b), undercut-shaped locking portions 26a protrude from the inner surface of the upper frame outer wall 26C at multiple locations (four locations in this embodiment) around the circumference, and are capable of locking onto the locking portions 21a of the lower frame outer wall 21C, with windows 26b formed above the locking portions 26a. The lower frame portion 21 and the upper frame portion 26 are fitted together via undercut-shaped locking portions 26a, which prevents rattling between the lower frame portion 21 and the upper frame portion 26 when only the lid member 20 is held. Furthermore, the lower surface of the upper frame top wall 26A is provided with a circumferentially protruding convex rib 26c that abuts against the upper surface of the lower frame top wall 21A when the upper frame portion 26 is attached to the lower frame portion 21.

[0019] A protruding portion 22 is provided at a forward position (front surface) of the cover member 20. The protruding portion 22 is formed by extending a portion of the front side of the lower frame portion 21 and the upper frame portion 26 radially outward in a generally trapezoidal shape in plan view. Of the lower frame outer wall 21C and the upper frame outer wall 26C that constitute the overhanging portion 22, the lower frame outer wall 21C that is parallel to the hinge portion 29 is the lower frame front wall 21C1, and the upper frame outer wall 26C that is similarly parallel to the hinge portion 29 is the upper frame front wall 26C1. A child lock mechanism (CR mechanism) A is provided on the front surface of the lid member 20, i.e., the front surface of the overhanging portion 22, and is configured with upper locking portion 21b, lower locking portion 21d, and engagement protrusion 26e and knob portion 26g that are provided on the upper frame front wall 26C1, which will be described later.

[0020] The child lock mechanism (CR mechanism) A will be explained below. 1 and 2, a generally trapezoidal engagement hole 26d is formed in the front surface of the upper frame outer wall 26C, more specifically, in the center of the front surface of the upper frame front wall 26C1. Undercut engagement protrusions 26e protruding radially inward are formed on the inner surface of the upper frame front wall 26C1 at the lower end of the engagement hole 26d (see FIG. 3(a)). Furthermore, a pair of first slits 26f are formed on the front surface of the upper frame front wall 26C1 on both sides of the engagement hole 26d. The lower end of the upper frame front wall 26C1 is opened, forming an inverted V-shape. Furthermore, the upper frame top wall 26A constituting the protruding portion 22 is formed with a knob 26g that stands upright integrally therewith, and a second slit 26h that is an elongated hole-like cavity that penetrates the upper frame top wall 26A. The knob portion 26g and the second slit 26h are both arranged parallel to the hinge portion 29, and the width (slit length) of the second slit 26h is set longer than the spacing between a pair of lower locking portions 21d, which will be described later.

[0021] As shown in Figures 1, 2, and 3(a), the upper part of the lower frame front wall 21C1 is formed with an upper locking portion 21b that protrudes radially outward from the lower frame top wall 21A, and a notch 21c is formed below the upper locking portion 21b. Furthermore, a pair of lower locking portions 21d each having a substantially U-shaped retaining portion 21d1 is provided at the lower end of the lower frame front wall 21C1. The retaining portions 21d1 of the pair of lower locking portions 21d are disposed on the front surface of the upper frame front wall 26C1 and are provided at a predetermined interval inside the pair of first slits 26f. An R portion 21b1 with a predetermined curvature radius is provided at the upper part of the upper locking portion 21b, and an engagement corner portion 21b2 is provided at the lower end thereof.

[0022] In the closed state, the CR mechanism A is in the ON state, i.e., the upper locking portion 21b protrudes forward of the upper frame front wall 26C1 through the notched hole 21c and the engagement hole 26d formed in the upper frame front wall 26C1. The lower end of the engagement protrusion 26e (which is also the lower end of the lower frame front wall 21C1) is housed in the lower locking portion 21d, bringing the upper frame front wall 26C1 and the lower frame front wall 21C1 close to each other, preventing the upper frame front wall 26C1 from spreading outward in the radial direction.

[0023] Next, the effects of the lidded container having the above-described structure will be described. 1. Abnormal lid opening operation In the closed state, if an abnormal lid-opening operation is performed, for example, by gripping with five fingers on upper frame outer wall 26C or upper frame front wall 26C1 and forcibly pulling up lid body 25, lid body 25 will initially rotate around hinge portion 29 as a fulcrum, causing upper frame portion 26 to attempt to separate from lower frame portion 21. However, because CR mechanism A is in the ON state, engaging protrusion 26e provided on upper frame front wall 26C1 on the protruding portion 22 side abuts against engaging corner portion 21b2 of upper lock portion 21b, preventing the rotation, thereby preventing lidded container 1 from reaching the open state.

[0024] 2. Normal lid opening operation To properly open the lid 25, the CR mechanism A must be in the OFF state. Specifically, as shown in FIG. 4(a), a first operation is performed in which the knob 26g is held and pulled upward. Then, as shown in FIG. 4(b), a second operation is performed in which the knob 26g is pushed backward (toward the hinge 29). By pulling the knob 26g upward, the engagement protrusion 26e on the upper frame front wall 26C1 can be pulled out from within the lower locking portion 21d. Pushing the knob 26g backward prevents the engagement protrusion 26e from engaging with the engagement corner 21b2 of the upper locking portion 21b. Therefore, by further pulling the knob 26g upward from this state, the lid 25 can be properly opened.

[0025] As described above, a pair of first slits 26f are formed on the front surface of upper frame front wall 26C1 (upper frame outer wall 26C), which constitutes upper frame portion 26, and second slits 26h are formed on upper frame top wall 26A. Therefore, when the second operation is performed, upper frame front wall 26C1 located between the pair of first slits 26f easily elastically deforms forward, and the width of second slit 26h deforms, assisting the elastic deformation forward of upper frame front wall 26C1, so that tab 26g can be easily pushed backward, which improves operability when opening the lid.

[0026] 5, to close the lid body 25, the knob 26g is pinched and pushed down or the upper frame top wall 26A is pushed downward, causing the upper locking portion 21b to protrude forward of the upper frame front wall 26C1 through the cutout hole 21c and the engagement hole 26d, and the engagement protrusion 26e to be housed in the lower locking portion 21d, thereby returning the CR mechanism A to the ON state. At this time, the inner surface of the undercut-shaped engagement protrusion 26e slides on the curved portion 21b1 of the upper locking portion 21b, allowing the engagement protrusion 26e to be smoothly housed in the lower locking portion 21d.

[0027] As described above, in order to properly open the lid of the lidded container 1 having the above-described configuration, it is necessary to first set the CR mechanism A to the OFF state, i.e., to perform the first operation of holding the knob 26g and pulling it upward, and the second operation of pushing the knob 26g backward in succession.However, since such successive operations are extremely difficult for young children to open, a child lock function can be added. In contrast, the operation of turning the CR mechanism A to the OFF state as described above is a simple enough operation for an adult or the like, and therefore the lid body 25 can be easily opened.

[0028] The configuration and effects of the present invention have been described above in accordance with the embodiments, but the embodiments of the present invention are not limited to those described above.

[0029] For example, in the above embodiment, a cylindrical container has been shown and described as the container with lid 1, but the container may have other shapes, such as a box-like or polygonal shape.

[0030] In addition, in the above embodiment, a configuration was shown and described in which the CR mechanism A is provided on the protruding portion 22, which is a portion of the cover member 20 extended forward, but it is also possible to provide the CR mechanism A directly on the lower frame portion 21 and the upper frame portion 26 without providing the protruding portion 22.

[0031] Furthermore, in the above embodiment, the lid body 25 and the lower frame portion 21 are integrally formed via the hinge portion 29. However, the lid body 25 and the lower frame portion 21 may be formed as separate members without the hinge portion 29. In this case, it is preferable to provide the CR mechanism A on both the front and rear sides. In this case, the lower frame portion 21 may also be integrally formed with the flange 11 of the container body 10. [Industrial Applicability]

[0032] The present invention can expand the applications of lidded containers equipped with child lock functions to an even wider range of areas. [Explanation of symbols]
