Description

[Technical Field]

[0001] The present invention relates to a child-resistant container with a lid. [Background technology]

[0002] In order to prevent accidents caused by young children and others imitating the actions of adults around them and removing the lid of a container without understanding the danger of the contents contained in the container, putting the contents in their mouths and accidentally eating or swallowing them, there are known containers with lids that have a function on the lid that makes it difficult for young children and others to remove them, i.e., a so-called child-resistant function (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-resistant 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 same release operation at least twice for both the first fitting portion and the second fitting portion, which is cumbersome for users who fully understand the characteristics of the contents to be stored. SUMMARY OF THE INVENTION In order to solve the problems of the prior art described above, an object of the present invention is to create a lidded container with a child-resistant function that allows the lid to be opened with a single release operation. [Means for solving the problem]

[0005] 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 has a fitting portion 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 to the inside and outside of the lower frame top wall, and the upper frame portion has an upper frame top wall, and upper frame inner and outer walls disposed opposite to the inside and outside of the upper frame top wall, The fitting portion has an operating portion on its outer surface and is configured to include an upper frame fitting piece formed by extending a portion of the upper frame outer wall downward, a lower frame fitting portion formed at the tip of an extension of a portion of the lower frame top wall, and the lower frame outer wall, and the upper frame fitting piece is inserted into an insertion hole formed in the lower frame fitting portion, and is arranged in an insertion space where the lower frame fitting portion and the lower frame outer wall that supports the upper frame fitting piece outward are opposed to each other, It is characterized in that the engaged protrusion formed on the inner surface of the lower frame fitting portion and the engaging protrusion formed on the outer surface of the lower end of the upper frame fitting piece are capable of engaging with each other. In the first means of the present invention, the outer wall of the lower frame supports the upper frame mating piece outward, requiring more pushing force, making it impossible to easily release the engagement between the engaged protrusion and the engaging protrusion, thereby maintaining the child resistance function, and allowing the engagement to be released in a single operation by pressing the operating part with great force.

[0006] The second means of the present invention is the above-mentioned first means plus the means that a pressing protrusion capable of abutting against the inner surface of the upper frame fitting piece is provided on the outer surface of the lower frame outer wall. With the above means, the pressing projection can come into contact with the inner surface of the upper frame fitting piece, and the outer wall of the lower frame can additionally support the upper frame fitting piece.

[0007] The third aspect of the present invention is the above-mentioned first or second aspect, with the addition that the lower frame portion and the lid body are rotatably connected via a hinge portion. 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.

[0008] A fourth 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]

[0009] The present invention has the above-described configuration, and therefore is provided with a child-resistant function and the lid can be opened with a single release operation. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Figure 1 is a plan view of a lidded container showing an embodiment of the present invention, Figure 2 is a front view of the lidded container, Figure 3 is a cross-sectional view taken along the arrows III-III in Figure 2 showing the lid closed state, Figure 4 is a cross-sectional view similar to Figure 3 showing the lid open state, and Figure 5 shows a cross-sectional view of the fitting portion, where (a) is a cross-sectional view of the lid closed state and (b) is a cross-sectional view showing the release operation.

[0012] 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.

[0013] 2 to 4, the container body 10 is a bottomed, rectangular cylindrical (box-shaped) member having a peripheral wall 13 that gradually expands in diameter upward to form a space inside, and a bottom wall 14 at the lower end of the peripheral wall 13. The peripheral wall 13 has a pair of horizontal peripheral walls 13a that are arranged opposite each other in the short direction and extend in the longitudinal direction, and a pair of vertical peripheral walls 13b that are arranged opposite each other in the long direction and extend in the short direction, and is configured to have a storage space S1 with a rectangular cross section inside them. The upper end of the opening 12, i.e., the upper end of the peripheral wall 13, is surrounded by a flange 11 that is formed like an outer brim from the upper end of the peripheral wall 13.

[0014] As shown in FIG. 1, the lid member 20 is composed of a lower frame portion 21 that is attached to the flange 11 and a lid body 25 that completely closes the opening 12. 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.

[0015] The lower frame portion 21 is a member formed to have a generally U-shaped cross section and a generally rectangular shape in plan view, with a lower frame top wall 21A and lower frame inner and outer walls 21B and 21C facing each other on the inside and outside of the lower frame top wall 21A. A lower frame opening 21D is formed inside the lower frame inner wall 21B, allowing it to be assembled onto the flange 11 of the container body 10. The lower frame top wall 21A has a pair of horizontal lower frame top walls 21A1 extending in the longitudinal direction and a pair of vertical lower frame top walls 21A2 extending in the lateral direction. Through holes 21a are drilled in multiple locations (eight locations in this embodiment) in the horizontal lower frame top wall 21A1 near the lower frame outer wall 21C. Undercut-shaped claws 21b protrude from the inner surface of the lower frame outer wall 21C corresponding to the through holes 21a. When the lower frame portion 21 is assembled to the flange 11, the claws 21b climb over the flange 11 and lock onto its edge, making it possible to firmly assemble the lower frame portion 21 to the flange 11.

[0016] As shown in Figures 2 and 5(a) and (b), a lower frame fitting portion 24 is formed in the center of the front side of the lower frame outer wall 21C. The lower frame fitting portion 24 is formed by extending a portion of the lower frame top wall 21A horizontally outward (forward) and bending its tip downward, forming a generally L-shaped cross section. A rectangular insertion hole 24a is formed in the lower frame fitting portion 24, and an insertion space S2 extending from the insertion hole 24a is formed between the opposing lower frame outer wall 21C and the lower frame fitting portion 24. A pressing protrusion 21c protruding outward is provided at the lower end on the outer surface of the lower frame outer wall 21C. Furthermore, an engaging protrusion 24b is provided on the inner surface of the lower frame fitting portion 24.

[0017] 1 and 5(a) and (b), the lid body 25 is configured to include a rectangular upper frame portion 26 and a flat 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, and is formed to be generally U-shaped in cross section and rectangular in plan view. The cover plate 27 is connected to the upper frame inner wall 26B via a groove 28 that is rectangular in plan view and formed around the outer edge of the cover plate 27.

[0018] 2 and 5(a) and (b), a fitting portion A is provided at the center of the front side of the upper frame outer wall 26C, the fitting portion A including an upper frame fitting piece 26D formed by extending a portion of the upper frame outer wall 26C downward, an insertion hole 24a formed in the lower frame fitting portion 24, and the lower frame outer wall 21C, and allowing the lid member 20 to be opened and closed. The upper frame outer wall 26C and the upper frame fitting piece 26D at its lower end are inserted into the insertion hole 24a on the lower frame portion 21 side, and are disposed in an insertion space S2 where the lower frame fitting portion 24 and the lower frame outer wall 21C, which supports the upper frame fitting piece 26D outward, face each other.

[0019] An engaging protrusion 26b protruding outward is provided at a lower position on the outer surface of the upper frame fitting piece 26D. The engaging protrusion 26b is engageable with the engaged protrusion 24b and is formed at approximately the same height as the pressing protrusion 21c. In addition, a protruding rib 26a extending in the longitudinal direction is provided on the underside of the upper frame top wall 26A. The protruding rib 26a abuts against the upper surface of the vertical lower frame top wall 21A2 when the upper frame portion 26 is attached to the lower frame portion 21. In addition, an operating portion 26c consisting of multiple (three in this embodiment) parallel-arranged protrusions is formed on the outer surface of the upper frame outer wall 26C and at the upper position of the engaging protrusion 26b (also on the outer surface of the upper frame fitting piece 26D), and as shown in Figure 2, when the lid is closed, the operating portion 26c is positioned within the insertion hole 24a and is exposed to the outside and visible.

[0020] 1, 3, and 4, hinge portion 29 is thinly formed between the lower end of lower frame outer wall 21C provided at the rear rear side and the lower end of upper frame outer wall 26C to connect them together. Hinge portion 29 may be formed intermittently along the longitudinal direction as shown in FIG. 1, or may be formed continuously.

[0021] The lid member 20 is assembled by pressing the lower frame portion 21 downward from a state in which it is placed on the flange 11 on the container body 10 side, and each claw portion 21b climbs over the flange 11 and engages its edge. As shown in Figures 3 and 4, the lid member 20 is configured to be rotatable around the hinge portion 29, and by fitting the upper frame portion 26 into the lower frame portion 21 and closing the opening 12 with the lid body 25, the lidded container 1 can be set in a closed state.

[0022] As shown in the enlarged view of FIG. 2 and FIG. 5(a), in the closed state of the fitting portion A, the engaging protrusion 26b of the upper frame fitting piece 26D disposed within the insertion space S2 is engaged with the engaged protrusion 24b provided on the inner surface of the lower frame fitting portion 24. Furthermore, the pressing protrusion 21c formed on the lower frame outer wall 21C abuts and presses against the inner surface of the upper frame fitting piece 26D, creating a tight fit. Alternatively, the pressing protrusion 21c is positioned close to the inner surface of the upper frame fitting piece 26D. Therefore, in the fitting portion A, the engagement between the engaging protrusion 26b and the engaged protrusion 24b is difficult to disengage, allowing the lidded container 1 to reliably maintain the closed state. In the closed state, even if an attempt is made to forcibly push up the lid body 25 without pressing the operating portion 26c, the engaging protrusion 26b and the engaged protrusion 24b are tightly engaged, preventing the contents contained in the container body 10 from being removed. That is, a child-resistant function is achieved that can adequately prevent attempts by small children to remove the container by mischief, and it is possible to prevent the contents from being accidentally put in one's mouth.

[0023] Next, to open the lid member 20, as shown in FIG. 5(b), a finger or the like is inserted into the insertion hole 24a provided in the lower frame fitting portion 24 and the operating portion 26c is pressed firmly against the operating portion 26c. This causes the upper frame outer wall 26C, particularly the lower end (upper frame fitting piece 26D) having the operating portion 26c, to deform around the protruding rib 26a as a fulcrum, and together with the lower frame outer wall 21C that had been pressing the upper frame fitting piece 26D outward, the upper frame fitting piece 26D can be deformed inward and inclined away from the lower frame fitting portion 24, thereby releasing the engagement between the engaging protrusion 26b and the engaged protrusion 24b. Therefore, by pressing firmly against the operating portion 26c and pulling it upward, the lid member 20 can be rotated in the opening direction around the hinge portion 29 as a fulcrum, as shown in FIG. 4, to enter the open state.

[0024] In this way, in the present invention, by performing a single release operation on fitting portion A, more specifically, on operating portion 26c provided on upper frame outer wall 26C, it is possible to release the engagement between engaging protrusion 26b and engaged protrusion 24b and set the lid in an open state. In other words, it is possible to sufficiently ensure ease of removal of lid body 25.

[0025] Moreover, in the present invention, because the pressing protrusions 21c formed on the lower frame outer wall 21C abut against the inner surface of the upper frame fitting piece 26D, a force is required to simultaneously press both the lower frame outer wall 21C and the upper frame fitting piece 26D to open the lid 25. This allows for fitting part A to be made difficult for small children and the like to disengage, while also allowing for a lidded container 1 equipped with fitting part A that is easy to operate and can be disengaged with a single operation by a person (an adult) who fully understands the characteristics of the contents to be stored.

[0026] Furthermore, even if the number of times the operating portion 26c is used increases and the upper frame fitting piece 26D develops a tendency to deform in an inwardly inclined shape, the lower frame outer wall 21C can provide additional support to the upper frame fitting piece 26D, thereby maintaining the engagement between the engaging protrusion 26b and the engaged protrusion 24b at the fitting portion A and achieving a child resistance function.

[0027] The configuration and effects of the present invention have been described above in accordance with the examples, but the present invention is not limited to the above examples. For example, in the above embodiment, a box-shaped container has been described as a container with a lid, but the container may be a cylindrical container, a polygonal container, or any other shape.

[0028] Furthermore, in the above embodiment, the fitting portion A is provided in only one location, but it is also possible to provide it in multiple locations depending on the size of the lidded container.

[0029] 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 fitting portion A on both the front side and the back side. In this case, the lower frame portion 21 may also be integrally formed with the flange 11 of the container body 10. [Industrial Applicability]

[0030] The present invention can expand the range of applications in the field of lidded containers with child-resistant features to an even wider range. [Explanation of symbols]
