The present invention relates to a handle-mounted container handle coupling structure, and in particular, in molding a synthetic resin container, the handle is applied to various synthetic resin containers having a thin thickness such as soy sauce container, cooking oil container, bottled water container, etc. The purpose is to improve the assembly of the binding ring by protruding a short projection on the hooked piece to prevent the detachment in the installation of the handle by inserting a number of hooked pieces on the neck of the container so that they can be conveniently combined after use. It is designed as.

Conventionally, the liquid container is formed integrally with the handle and the container body has a lot of difficulties in the production and this has been a factor of the cost increase, to solve this problem, to form a male thread on the neck portion of the container and the handle is separated while manufacturing the binding The internal thread was formed inside the ring to fix each other, but there is a problem that the assembly is inconvenient and intrusive, which is not practical.

In order to improve this, in recent years, a packaging container with a handle, such as Japanese Patent Application No. 63-175036, has been developed and used as shown in Fig. 4, but the structure is such that the container has a lower portion from the neck of the container (2). To the handle-packing packaging body (1) consisting of a handle attachment part (8) which is extrapolated to the diameter (4) beyond the diameter of (2), and a handle which is integrally addressed to the handle part (11) from the handle attachment part. The end toothed part 3 and the annular groove part 7 and the end toothed part 3 and the annular groove part 7 of the shape which were throttled in the upper part and the lower part of the container side in the extrapolation part of the said handle attachment part 8, respectively. The uneven portion 6 formed on the outer surface between the upper and lower portions 10 and the undercut 10 fitted to the annular flange 9 and the annular groove 7 which are external to the shoulder at the upper and lower sides of the handle attaching portion 8. At the same time through the adhesive 12 between the handle attachment portion 8 and the uneven portion 6 Although the packaging container with handles has been developed, the adhesive is used between the attachment part and the uneven part to fix the handle and the container with the adhesive part to stably fix the handle and the container. Since the attachment fixing means is essential, the user has many difficulties in use without the expert knowledge, and thus it is not suitable for actual use.

In order to solve the above problems, the present invention opens a plurality of hooking pieces with one indentation portion and one short protrusion on the neck of the container, and forms a plurality of stepping stones formed inside the step of the binding ring in which the handle is formed. In order to make the protrusion of the protrusion on the selected step, the short protrusion of the container is inserted into the check fitting, so that the handle binding ring is stably assembled. This will be described in detail by the accompanying drawings as follows.

In the lower portion of the neck portion 102 of the container 101, the recessed portion 106 and the locking projection piece 107 are alternately arranged on the outer surface, and one of the locking projection pieces 107 is downward. Short projection 107A integrally protruded, the lower end of the inclined surface (110B) one end of the engagement ring (108) having an inward projection (110) having a top step 110A, and a concave inlet (109). The handle 111 is formed to integrally form the projection engaging groove (108A) in the selected one of the inwardly projecting portion of the binding ring extended to the short projection and the coupling groove to ensure that the binding ring is stably coupled to the container.

In the figure, reference numeral 103 denotes an outlet and 105 a plug.

When described in detail by the accompanying drawings the effect of the present invention configured as described above are as follows.

When the binding ring 108 is forcibly fitted to the urine inlet ring 106 formed in the neck portion of the container 101, and the coupling ring 108 is rotated in a concentric manner at a predetermined angle, the indentation of the container 101 is provided. Protrusion engaging groove formed in the inward projection 110 of the binding ring 108 on the locking projection piece 107 of the container while the inwardly projecting portion 110 of the binding ring 108 guided and inserted is rotated slightly in the circumferential direction 108A is caught by the short protrusion 107A so that the engagement ring 108 cannot be easily pulled out.

At this time, the short projection 107A of the locking projection piece 107 and the projection coupling groove 108A formed on the upper end 110A of the projection 110 act like a locking device, so that the binding ring 108 is applied with a strong external force. It does not work and prevents the lung from falling out.

As described above, it can be assembled and separated by a simple assembly process, and is coupled to each other by the engaging action of the engaging groove on the projection of the engaging protrusion and the inward projection, and in particular, by preventing the binding ring from rotating by the coupling of the projection and the engaging groove. It is a very practical and useful design with the advantage of maintaining a solid defect state.

Claims (1)

In a container that combines the handle, a plurality of urine indents and hooking pieces are alternately arranged on the neck of the container, and one of the hooking pieces is formed by integrally protruding short protrusions downwardly, and the handle is integrally bound. On the inner surface of the container to be coupled to the same number of indents and inward protrusions to be in turn, but the projections in the selected one inward projections to the projection projection grooves short short formed on the engaging projection of the container is forced to the coupling groove Container handle coupling structure characterized in that the fitting to be fitted in a stable form.
