Description

  The present invention relates to a garbage container such as a plastic bottle, a can or general garbage.

  In general, in order to mold a plastic container, an injection blow molding method is employed in which a preform previously molded corresponding to the container is heated and air is blown into a container shape.

  On the other hand, an injection blow molding method that performs preform injection molding, stretch blow molding, and product removal in a series of processes has also been proposed, and the advantage of eliminating the need to reheat preforms in beverage and other bottling manufacturers In recent years, it has been introduced to bottling manufacturers. In particular, in the case of large containers such as tens of liters, such as garbage containers, the latter injection blow molding method is difficult because it is not easy to reheat a preform having a size corresponding to the garbage container. It is conceivable to mold with.

  In this case, as shown in FIG. 7, after the container main body 2 and the lid 3 constituting the garbage container 1 are integrally formed through the connection part x, the connection part x is cut and removed, and the container main body 2 and the lid body are removed. 3 (see FIG. 8), and the lid body 3 is combined with the container body 2 to form the garbage container 1.

In addition, not only the injection blow molding method but shaping | molding a garbage container with a plastic is performed widely (for example, refer patent document 1).
JP-A-8-239101

  By the way, in the garbage container formed by the injection blow molding method described above, an open neck portion 31 (see FIG. 7) for blowing air into the preform is formed, and the opening of the neck portion 31 needs to be closed. There is. That is, the cap is attached to the neck portion 31 and the opening thereof is closed. At that time, the cap is mistaken as an insertion port for a can and the like, and a malfunction occurs when the cap is removed to discard the can and the like. There is a fear.

  The present invention has been made in view of such a problem, and when molding a garbage container by an injection blow molding method, a garbage container capable of reliably closing the opening of the neck portion so as not to be mistaken for an input port. Is to provide.

  The present invention relates to a waste container formed by integrally forming a container main body and a lid body by an injection blow molding method, and cutting and removing a connection portion between the container main body and the lid body, and a neck portion formed on the lid body. A cap having a handle portion is integrally attached.

  According to the present invention, since the cap having the handle portion is integrally attached to the neck portion of the lid body, the cap grip portion can be grasped and used when removing the lid body. For this reason, it can grasp | ascertain at a glance that a cap is a handle of a cover body, and the possibility of malfunctioning, such as rotating a cap misunderstood as a slot, can be eliminated.

  In the present invention, when the container body and the lid are transparent bodies and the cap is a colored body, it is possible to grasp the amount and contents of cans and general garbage dumped in the container body, and the transparent body It is possible to produce an aesthetic with a novel design.

  In the present invention, it is preferable that a charging port is formed in the lid, because containers such as cans and plastic bottles can be discarded without opening the lid. In this case, the size and shape of the inlet can be changed according to the container.

  In the present invention, it is preferable that the lid body is detachably fixed to the container main body via a hook member because the lid body can be fixed to the container main body.

  According to the present invention, when the garbage container is formed by the injection blow molding method, the opening of the neck portion can be reliably closed so as not to misunderstand the opening.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 and 2 show an embodiment of the garbage container 1 of the present invention.

  The garbage container 1 includes a substantially square tube-shaped container body 2, a substantially pyramid-shaped lid body 3 that is detachably attached to the peripheral edge of the upper end opening of the container body 2, and covers the upper end opening. The cap 4 is integrally attached to the body 3, and the hook member 5 is provided on the lid body 3 so as to be rotatable and fixes the lid body 3 to the container body 2.

  Here, the container main body 2 and the lid 3 constituting the garbage container 1 are transparent, and as shown in FIGS. 7 and 8, the container main body 2 and the lid 3 are connected to each other by an injection blow molding method. It is formed integrally with x, and then the connecting portion x is cut and removed to separate the container body 2 and the lid 3.

  In addition, the lid 3 has an upper surface formed with a neck portion 31 for blowing air in the injection blow molding method, and has an inlet 3a formed on one inclined surface.

  On the other hand, the cap 4 is a colored body, and is formed separately from the container main body 2 and the lid 3 as shown in FIGS. 3 to 5, and is formed in a substantially spherical crown shape. The outer peripheral edge is formed so as to be continuous with the outer peripheral edge of the upper surface excluding the three neck portions 31. A locking piece 41 having a locking portion 41 a that can be mounted on the neck portion 31 of the lid 3 is suspended from the back surface of the cap 4, and a pair of symmetrical recesses as viewed from above on the front side. 4a is formed. Therefore, a grip portion 4b having a set width is formed between the pair of recesses 4a.

  Here, the cap 4 is integrally attached to the lid body 3 via the locking portion 41 a by forcibly pushing the locking piece 41 into the neck portion 31 of the lid body 3.

  Although not shown in detail, the garbage container 1 configured as described above contains a garbage bag and is locked therein, and is disposed in a home, factory, office, station, event venue, or the like. And a plastic bottle, a can, etc. can be discarded through the insertion port 3a of the cover body 3. FIG. At this time, since the container body 2 and the lid body 3 are transparent, it is possible to intuitively grasp the type, contents or amount of a container such as a can discarded inside, and the novel design of the transparent body. Can produce aesthetics.

  When the container is accommodated in a certain amount and it is necessary to replace the garbage bag, after the fixing by the hook member 5 is released, if the handle 4b of the cap 4 is grasped and lifted, the lid from the container body 2 3 can be removed. Next, the locked state is released and the garbage bag containing the container is pulled up. Instead, after a new garbage bag is stored, the handle 4b of the cap 4 is grasped and the lid 3 is attached to the container body 2, The lid member 3 may be fixed to the container body 2 by operating the hook member 5.

  By forming the grip portion 4b for grasping the lid body 4 on the cap 4 integrally attached to the lid body 3 in this way, it is possible to grasp at a glance that the cap 4 is not an inlet, A malfunction such as rotating the cap 4 can be reliably prevented.

  In addition, by preparing the cover body 3 which formed the inlet 3a according to the kind of containers, such as a PET bottle, a steel can, and an aluminum can, and preparing the some container main body 2 corresponding to each cover body 3 It becomes possible to collect separately for each container.

  In the above-described embodiment, the case where the cap 4 is a colored body has been illustrated. However, the cap 4 is not necessarily a colored body, and may be a transparent body.

  By the way, in the embodiment described above, the trash container 1 in which the inlet 3a is formed in the lid 3 is illustrated, but as shown in FIG. 6, it is not always necessary to form the inlet in the lid 3. Such a garbage container 1 can also be used when collecting general garbage etc. by being disposed in a home, factory, office, station, event venue or the like.
