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. Other than the portion provided with the lid, the lid body is provided at an edge portion that is separated from the container main body when opened, and the lock mechanism is an operation member provided integrally with the distal end portion of the operation member support portion of the lid body. And an engaging edge formed on the container main body, and the operating member includes an operating part that protrudes upward and a claw part that has a locking claw that extends downward and is hooked on the engaging edge. is there.

  When the lid attached to the container body with a hinge is closed, the lock claw of the operation member goes over the locking edge of the container body and goes to the lower side. It is caught on the edge and the lid is kept closed (locked state). In order to release the lock, if the operation part protruding above the operation member is tilted (pushed or pulled) (if operated), the lock claw and the lock edge can be unlocked. If the lid is moved in the direction of opening the lid while tilting the operating section (if the lid is lifted), the lock claw passes through the engaging edge and the lock is released.

  It is difficult for an infant to unlock and open the lid because the two operations of manipulating the operation part of the operation member and the operation of lifting the lid have to be performed almost simultaneously (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 lid flange that protrudes outward is provided on the lid body at a location where the lock mechanism is provided.

  In the case of a container with a lid in this mode, for example, a thumb of the right hand is hung on the edge of the lid flange, and the lid is lifted with the thumb while operating the operating part of the operating member with the index finger (for example, pulling or pushing forward). In this way, the lid can be opened. That is, the unlocking operation and the lid opening operation can be performed with one hand.

  In another embodiment, the edge of the lid and the edge of the opening of the container body are formed by protruding frame portions that fit in each other.

  Further, first and second holes are respectively formed in the edge of the lid and the edge of the opening of the container body, and the operation member is provided in the inner edge of the first hole of the lid (that is, The inner edge of the first hole is the tip of the operation member support part), and the locking edge is formed by the inner edge of the second hole of the container body.

  More preferably, the edge of the lid and the edge of the opening of the container body are respectively formed with first and second protrusions that rise upward and fit over each other at the location of the locking mechanism, The first and second holes are formed in the first and second protrusions, respectively.

  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 locking mechanism includes an operation member integrally formed substantially perpendicularly to the surface of the lid body at a distal end portion of the operation member support portion of the lid body, and a locking member formed on the frame body. The operation member includes an operation portion protruding to the opposite side of the frame body side, and a claw portion having a lock claw that extends to the frame body side and is hooked on the locking edge.

  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, the fitting frame portion 52 and the frame body 40 of the lid 50 are respectively formed with convex portions 56 and 46 that are raised upward on the front side of the container. Has been. The convex portion 56 of the fitting frame portion 52 is formed by deforming the frame portion 52 itself, and includes an outer wall surface 54A, an inner wall surface 55A, and an upper surface 53A. A portion from the upper surface 53A toward the upper surface portion 53 of the frame portion 52 is slightly curved. Similarly, the convex portion 46 of the frame body 40 is formed by deforming the frame body 40 itself, and includes an outer wall surface 42A, an inner wall surface 43A, and an upper surface 41A, and the upper surface portion 41A to the upper surface portion 41 of the frame body 40. The part facing is slightly curved. When the lid 50 is closed, the convex portion 56 exactly overlaps (fits) the convex portion 46.

  In the central portion of the upper surface 53A of the convex portion 56 of the lid 50, a square hole 57 is formed in the front half thereof. The hole 57 extends to the upper part of the outer wall surface 54A. An operation member 58 is formed integrally with the upper surface 53A at the inner edge portion (tip portion) of the upper surface 53A (support portion) looking into the hole 57. The operation member 58 is provided vertically (perpendicular to the surface of the upper surface portion 51 of the lid 50), and is coupled to the edge of the upper surface 53A at a position slightly lower than the middle of the length (of this edge portion). The tip is indicated by reference numeral 53a). The upper half of the operation member 58 protrudes upward from the hole 57 (the protrusion is the operation part 58A), the lower half enters the hole 57, and the lock claw protrudes outward at the lower end (claw part). 58B is integrally formed. A lid flange 59 that projects forward from the lower portion of the outer surface portion 54 is integrally provided on the frame portion 52 of the lid 50.

  On the other hand, a hole 47 is also formed in the upper surface 41A of the convex portion 46 at a position corresponding to a position directly below the operation member 58 when the lid 50 is closed. The edge 41a of the upper surface 41A is a locking edge that is seen in the hole 47 and faces the operation member 58 (when the lid is closed).

  When the front part of the lid 50 is pushed downward from the state in which the lid 50 is opened (when the lid is closed), the lock claw 58B of the claw part of the operation member 58 provided on the convex part 56 is formed on the upper surface of the convex part 46. Since the edge of the hole 47 (in the vicinity of the locking edge 41a) is pushed, the edge is turned downward and the lock claw 58B is slightly bent so as to escape from the edge, and the lock claw 58B is in the hole 47. to go into. Preferably, the lower portion of the lock claw 58B is rounded. It is desirable that the upper portion of the lock claw 58B is flat. In this state, even if the lid 50 is lifted upward in an attempt to open the lid 50, the lock claw 58B of the operation member 58 is caught on the locking edge 41a (as shown in FIG. 5), and the lid 50 cannot be opened (locked state). ).

  When opening the lid of the container, the operator hangs the thumb of one hand (for example, the right hand) on the front edge of the lid flange 59 in front of the container, and uses the index finger to project the operation part 58A protruding from the hole 57 of the operation member 58 to the front. The lid 50 is lifted by the thumb hung on the lid flange 59. When the operation part 58A is pulled forward, the front edge part (inner edge part) (the front edge part of the support part) (near the part indicated by reference numeral 53a) looking into the hole 57 on the upper surface of the convex part 56 becomes gentle, and the operation member Since the operation portion 58A is tilted forward, the lock claw 58B is retracted rearward and separated from the locking edge 41a (disengagement) (the state indicated by the chain line in FIG. 5). Therefore, if the lid 50 is moved upward, The lock claw 58B is pulled upward without being caught by the locking edge 41a. If the elasticity of the hinge 49 is weakened as described above, the lid 50 opens without the help of a person due to the elasticity of the hinge 49 when the locking claw 58B and the locking edge 41a are unlocked. It is necessary to lift the lid 50 by human power.

  The lock cannot be released unless the separate movements of the thumb and forefinger are linked as described above. Since it is difficult for an infant to perform two different movements (finger movements) at the same time, the locking mechanism having the above-described configuration is difficult for an infant to open. 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 lid must be lifted while pulling the operating part forward, making it a child resistant and senior friendly.

  In the above-described embodiment, the lock is released when the operation portion on the upper part of the operation member is pulled forward. However, the lock may be released when the operation portion is pressed. Further, the convex portions 56 and 46 are not necessarily required and may be flat. The sizes and positions of the holes 57 and 47 can be arbitrarily changed.
