Description

  The present invention makes it difficult for an infant to open a lid (child resistant (child lock)), but can be opened relatively easily even by an elderly person who is not necessarily strong (senior friendly). About.

  It is important to keep medicines, cosmetics, detergents, cigarettes, etc. out of the reach of children so that they cannot be touched by hand or accidentally put in their mouths. It is also necessary that the container itself has a child resistant (child lock) function. However, if it is difficult to open the lid, an adult who needs the above-mentioned items, especially an elderly person with weak gripping force, gripping force, and pressing force, will fall over at the end.

  Therefore, a child-resistant and senior-friendly improvement has been made that can be easily opened even by the elderly. For example, Patent Documents 1 and 2.

JP 2012-131533 A JP 2012-131534 A

  However, those described in these patent documents relate to caps that are used by screwing or crowning the mouth of containers such as liquids and viscous bodies, and are not improvements of the containers themselves.

  An object of the present invention is to provide a child-resistant and senior-friendly container that includes a lid that can be freely opened and closed, and that is open and closed.

  The present invention also provides a lid assembly as one component of the lidded container.

  In the container with a lid according to the present invention, a lid for closing the opening of the container main body is provided on the container main body so as to be freely opened and closed by a hinge, and a lock mechanism for holding the lid closed is a hinge. The lid body is provided at an edge part that separates from the container body part when opened except for the part provided with the lock mechanism, and the locking mechanism covers the front surface of the space formed on the lateral outer surface of the edge part of the lid body. A locking member held by an elastic member; a first locking claw is formed on the inner surface of the locking member; and a first locking claw that is locked to the first locking claw on the lateral outer surface of the upper edge of the container body. Two locking claws are formed. The lateral outer surface refers to the outer surface facing the lateral direction of the portion where the locking mechanism is provided, and may be the side surface as well as the front surface of the container.

  When the lid attached to the container main body by the hinge is closed, the first locking claw of the lock member goes beyond the second locking claw of the container main body, so that the lid is opened. Even so, the first locking claw is hooked on the second locking claw, and the lid is kept closed (locked state). If the lock member is pulled forward or tilted (operated) to release the lock, the locked state between the first locking claw and the second locking claw is released. If the lid is lifted in this state, the first latching claw passes through the second latching claw and is unlocked, and the lid is opened.

  Since the two operations of operating the lock member and lifting the lid must be performed almost simultaneously, it is difficult for an infant to unlock and open the lid (child resistant). From this point of view, it is sufficient if the hinge simply connects the lid to the container body so that it can be opened and closed, and it is not necessary to release the lock so that the lid rises due to the elasticity of the hinge. Strong elasticity (biasing force) that raises the lid is not necessary). Also, adults with learning ability can easily unlock and open the lid, even if they are not necessarily strong elderly people (senior friendly).

  In a preferred embodiment, a finger-hanging portion is provided to extend from at least one of the upward and downward directions from the lock member. The lock member can be easily operated using this finger-hanging portion.

  The space for arranging the lock member can be formed, for example, by making a hole or providing a notch at the edge of the lid. Preferably, the second locking claw is formed in a recess formed on the lateral outer surface of the upper edge portion of the container main body. In order to give appropriate elasticity to the elastic member, a waved elastic member may be used.

  In one embodiment of the present invention, the container with a lid includes a lid assembly, and the lid assembly includes a frame body and a lid body coupled to the frame body by a hinge, and the frame body is disposed on the container body. The container main body is configured by being fitted and fixed to the edge. And the said frame becomes a protruding item | line frame part.

  According to the above embodiment, the container body and the lid assembly can be separately molded. Of course, the container main body and the lid connected to the container main body by a hinge may be integrally formed. In any case, the container body and the lid (container body and lid assembly) are made of synthetic resin.

  The position where the number of the lock mechanisms is provided is arbitrary. For example, one locking mechanism is provided at the edge on the side opposite to the part where the hinge is provided, and two or more locking mechanisms are provided at the edge on the side opposite to the part where the hinge is provided. The locking mechanism is provided at an edge located on a side of a portion where the hinge is provided.

  The lid assembly includes a frame body that can be coupled to the upper edge of the container body, and a lid body that is coupled to the frame body by a hinge, and the frame body and the lid body are provided with a locking mechanism at a location other than the hinge portion. The lock mechanism includes a lock member that is held by an elastic member so as to close the front surface of the space formed on the lateral outer surface of the edge of the lid, and the first lock is provided on the inner surface of the lock member. A nail | claw is formed and the 2nd latching claw which latches to the said 1st latching claw is formed in the horizontal outer surface of a frame.

  The present invention further provides the above-described lid assembly which is one of the components of the lidded container.

It is a perspective view of the container with a lid by one Example. It is a disassembled perspective view of a container with a lid. It is an expanded sectional view which follows the III-III line of FIG. It is an expanded sectional view which follows the IV-IV line of FIG. It is an expanded sectional view which follows the VV line of FIG.

  FIG. 1 shows an entire container with a lid according to an embodiment of the present invention. FIG. 2 is an exploded perspective view of the lidded container shown in FIG.

  The lidded container 10 includes a container body 20 and a lid assembly 30. The lid assembly 30 includes a frame body 40 and a lid body 50. The lid 50 is hinged to the frame 40 at a plurality of locations (three locations in FIG. 2) on the rear side or the rear side (the side on which the lock mechanism 60 described later is provided is the front side or the front side). It is connected so that it can be opened and closed freely (see FIG. 3). The lid 50 and the frame 40 of the lid assembly 30 are integrally formed including the hinge 49. For example, the lid assembly is injection molded from polypropylene (PP). The container body 20 is created by sheet molding using polystyrene (PS). These can also be molded from polyethylene terephthalate (PET) or other synthetic resins. The hinge 49 is soft and does not require strong elasticity. For example, it is preferable that the lid 50 does not open upward due to the elasticity of the hinge 49 when the lock by the lock mechanism 60 is released as will be described later (the operator only needs to be able to lift and open it by hand or finger). ).

  First, the lid assembly 30, particularly the attachment of the frame body 40 to the container body 20 (strong coupling between the frame body 40 and the container body 20) will be described.

  The container body 20 is a container having a bottom and closed surfaces (side surfaces, bottom surfaces) other than the top surface. In this embodiment, the container body 20 is substantially rectangular as viewed from above and rounded at the four corners, but the shape and height can be arbitrarily designed. A flange 21 protruding outward is formed integrally on the upper edge of the container body 20 over the entire circumference.

  On the other hand, the frame 40 of the lid assembly 30 has the same shape as the flange 21 when viewed from the top so as to fit the flange 21 of the container body 20, and the upper surface protrudes upward (projections), and the groove is formed on the lower surface. Is formed. This ridge or groove is defined by an upper surface portion 41, an outer surface portion (wall portion) 42 and an inner surface portion (wall portion) 43. And the nail | claw part 44 which protrudes inwardly in the inner surface lower part of the outer surface part 42 is provided in several places (refer FIG. 3, FIG. 4). In the example shown in FIG. 2, claw portions 44 are provided at four positions on the front side and four positions on the rear side. A hole 45 formed in the upper surface portion 41 indicated by reference numeral 45 is formed to make the claw portion 44 thick.

  When the flange 21 of the container body 20 is forcibly press-fitted into the groove opened on the lower side of the frame body 40 of the lid assembly 30, the outer surface portion 42 of the frame body 40 is deformed outward and the claw portion 44 bends the flange 21. However, since the flange 21 is sandwiched between the upper surface portion 41 and the claw portion 44 of the frame body 40, the frame body 40 is firmly fixed to the flange 21 of the container body 20. It is preferable that the lower surface of the claw portion 44 has a slope (planar surface or curved surface) inclined upward inward so that the claw portion 44 can easily enter the lower side of the flange 21, so that the claw portion 44 is not easily detached from the flange 21. The upper surface of the claw portion 44 is preferably a flat surface parallel to the lower surface of the flange 21.

  The lid body 50 of the lid assembly 30 includes an upper surface portion 51 and a fitting frame portion (edge portion) 52 integrally formed over the entire periphery of the edge portion of the upper surface portion 51. The fitting frame portion 52 has the same shape as the frame body 40 when viewed from above so that it can be fitted into the frame body 40 (with a slight gap), and the upper surface protrudes upward (projected) over the entire outer periphery of the lid body 50. In the lower surface side, a groove that can accommodate the frame body 40 is formed. This ridge or groove (that is, the fitting frame portion 52) includes an upper surface portion 53, an outer surface portion (wall portion) 54, and an inner surface portion (wall portion) 55 (see FIGS. 3 and 4). The hinge 49 is continuous with the outer surface portion 54.

  When the frame body 40 is coupled to the container body 20, the upper surface opening of the container body 20 is opened as the opening of the frame body 40. When the lid 50 of the lid assembly 30 is closed, the fitting frame portion 52 overlaps and fits with the frame body 40, and the upper surface portion 51 closes the upper surface opening of the container body 20, that is, the lid is closed. If the front side of the lid 50 is lifted, the upper surface opening of the container body 20 opens.

  Therefore, from the viewpoint of covering the container, the frame body 40 is positioned as a part of the component on the container body 20 side. Therefore, the part on the container body 20 side in a state where the frame body 40 is joined is referred to as a container body part in this specification and is distinguished from the lid body 50. In this case, the frame 40 is a ridge frame provided at the edge of the opening of the container body.

  The container body and the lid can be integrally formed by injection molding or the like. In this case, a portion corresponding to the frame body 40 is not necessary. That is, at least a portion corresponding to the flange 21 of the container main body and a portion corresponding to the upper surface portion 41 of the frame body will be integrated. A lid corresponding to the lid 50 is directly opened and closed by a hinge at an upper edge portion of the container body, for example, a portion corresponding to the flange 21. Also in such an embodiment, a portion on the container body side excluding a portion (lid body) corresponding to the lid body is referred to as a container body portion. And a protruding item | line frame part is integrally formed in the edge of the opening of a container main-body part.

  Now, a lock mechanism 60 for holding the lid 50 in a state where the opening of the container body is closed (closed state) is provided on the front surface of the container. In this embodiment, one locking mechanism 60 is provided, but two may be provided on the front surface of the container apart from each other, or may be provided on the side surface instead of or in addition to the locking mechanism on the front surface. There is no point in providing the hinge 49 at the edge part on the back side of the container, but it may be provided anywhere as long as the open lid 50 is a part away from the edge of the container body part. There is no limit.

  The lock mechanism 60 includes a member (structure, configuration) on the lid 50 side and a member (structure, configuration) on the container main body (the frame body 40 side of the lid assembly 30). In particular, referring to FIG. 5 in addition to FIGS. 1 and 2, a part of the upper surface portion 53 of the frame portion 52 is notched (or perforated) (notched or perforated) on the front surface of the lid 50. An inner edge is indicated by reference numeral 53B, and a portion whose width is narrowed by the notch of the upper surface portion 53 is indicated by reference numeral 53A), and a space (recess) 61 in which the lock member 62 can move is formed. The lock member 62 is held on the outer surface portion (lateral outer surface) 54 of the frame portion 52 by a thin corrugated elastic (spring) member 64 on both sides thereof. That is, the two elastic members 64 are thin plate-like ones continuing to the outer surface portion 54 at one end and continuing to the lock member 62 at the other end. The elastic member 64 and the lock member 62 are formed integrally with the frame portion 52. From the upper and lower ends of the lock member 62, finger hooks 62A and 62B protrude upward and downward. It suffices to have at least one of the finger hooks 62A and 62B. Further, a first locking claw (lock claw, protrusion) 63 is integrally formed on the inner surface of the lock member 62 so as to protrude inward. The upper surface of the first locking claw 63 is flat, and the lower surface is inclined upward inward.

  On the other hand, in the frame body 40 (container body portion), the outer surface portion (lateral outer surface) 42 of the frame body 40 is recessed at the portion corresponding to the space 61 of the lid 50 (the portion of the recessed outer surface portion is denoted by reference numeral 42A). A recess 46 is formed. A second locking claw (lock claw, protrusion) 47 is integrally provided on the concave portion 42A of the recessed portion 46. It is preferable that at least the lower surface of the locking claw 47 is flat. The upper surface of the locking claw 47 may be a slope. Since the width of the frame body 40 (the width of the upper surface portion 41) is narrowed by forming the recess 46, the corresponding portion of the flange 21 of the container body 20 that fits in the frame body 40 (reference numeral 21A). ) Is also narrower.

  In the configuration of the lock mechanism 60 described above, since both sides of the lock member 62 are held by the elastic members 64, the lock member 62 can move in the front-rear direction or obliquely (the upper part is outward or the lower part is outward).

  When the front portion of the lid 50 is pushed downward from the state in which the lid 50 is opened, the first locking claw 63 of the lock member 62 is provided in the second recess 46 provided in the recess 46 of the frame body 40 (container body). Since the lower part of the locking member 62 escapes outward when hitting the locking claw 47, the first locking claw 63 comes below the second locking claw 47. In a state where the lid 50 is completely closed (a state where the frame portion 52 is fitted to the frame 40), the first locking claw 63 is located below the second locking claw 47 as shown in FIG. Positioned and caught (locked). Therefore, even if the lid 50 is lifted, the first locking claw 63 hits the second locking claw 47 and the lid cannot be opened.

  If two fingers are put on the upper and lower finger hooks 62A and 62B of the lock member 62 and the entire lock member 62 is pulled forward, or the lower finger hook 62B is pulled forward and the lock member 62 is inclined (see FIG. 5), the first locking claw 63 is released from the second locking claw 47, and the lock is released. When the front part of the lid 50 is lifted in this state, the lid of the container is opened. As described above, when the elasticity of the hinge 49 is weakened, the lid 50 is moved by the elasticity of the hinge 49 when the first locking claw 63 and the second locking claw 47 are released. The lid 50 is prevented from being opened without borrowing power, and the lid 50 needs to be lifted by human power.

  As described above, the lock cannot be opened unless the two separate movements of releasing the lock by operating the lock member 62 and lifting the lid immediately thereafter are linked. Since it is difficult for an infant to perform two different actions at the same time, the lock mechanism having the above configuration is difficult to open for an infant. On the other hand, if the adult has learning ability, the lid opening operation is easy even for a weak person such as an elderly person.

  That is, the above-described locking mechanism locks at the same time as the lid is closed. In order to unlock and open the lid, the lock member must be pulled forward, and immediately after that, the lid must be lifted, making it a child resistant and senior friendly. In addition, since the locking claw for locking is on the back side of the locking member and is not visible from the outside, it is more difficult for an infant to open the lid.

  It should be noted that the elastic member does not necessarily have a corrugated shape, and various modifications are possible such that the finger-hanging portion may protrude forward.
