Description

  The present invention relates to a bottle with a handle, and in particular, to a PET resin bottle having an internal volume of 500 ml or less in which a handle member is integrally formed by insert molding.

  In order to simplify the carrying of the container, a bottle with a handle in which a handle member is formed separately as a bottle with a handle and is fixed to a part of the bottle by insert molding has been known ( For example, see Patent Documents 1 and 2).

JP-A-6-335958 JP-A-7-80921

The bottles with a handle described in Patent Documents 1 and 2 are both large-sized bottles, and the handle is insert-molded in the bottle body.
However, in the case of a small-capacity bottle of 500 ml or less, when the handle is attached to the body as in the prior art, the handle is changed, which hinders the carrying and handling of the bottle and impairs the beauty.

In the case of a small-capacity bottle, it is sufficient to hold the bottle itself by hand, so no consideration was given to attaching a handle to the bottle itself.
In order to improve the convenience and convenience of carrying the bottle, it may be possible to wrap a string around the neck of a small-capacity bottle, wrap the bottle itself in a bag, etc. The work for attaching a string etc. to a bottle was needed.

  In view of the above circumstances, the present invention provides a bottle with a handle in which the shape of the handle member is simplified and the handle is fixed to the shoulder portion of the bottle having an internal volume of 500 ml or less by insert molding. Objective.

  In order to solve the above problems, the present invention, as a small-capacity bottle with a handle, is made of PET resin with a bottle capacity of 500 ml or less, and a separately formed handle member is attached to the shoulder forming portion of the blow mold, A bottle in which a handle member is insert-molded on a shoulder portion of the bottle by blow molding a heat-softened preform, and the handle member includes a front wall surface and an upper wall continuously provided on the front side upper portion of the front wall surface. The handle wall includes a handle wall that is continuously provided from the lower surface of the outer edge of the upper wall via a hinge and has a handle hole in the center, and an engaging portion that is continuously provided on the back side of the front wall surface. A configuration is provided that includes a base portion continuously provided on the back surface of the front wall surface, and protrusions disposed so as to protrude from the base portion to the upper and lower sides and both side surfaces.

  Since the bottle with a handle of the present invention is attached by insert-molding a handle on the shoulder of a PET bottle having a capacity of 500 ml or less, the shape of the body panel surface is not changed. It was easy to carry and use.

It is an elevation view of the bottle with a handle according to the first embodiment of the present invention. It is a perspective view of a handle member. It is explanatory drawing of a bottle shoulder part, (a) is a top view, (b) is a cross-sectional elevation view.

Next, the bottle with a handle of the present invention will be described with reference to the drawings.
In FIG. 1, A is a stretch blow-molded bottle made of PET resin and has an inner volume of 500 ml or less, B is a handle member integrally formed by insert molding on a part of the shoulder of bottle A, and C is a shoulder of bottle A It is an engagement recessed part formed by insert-molding the handle member B in a part.
The bottle A includes a mouth part 1 and a shoulder part 2, and a body part 3 and a bottom part.
A lateral rib 4 is provided at the boundary between the shoulder 2 and the body 3.

As shown in FIGS. 1 to 3, the handle member B is connected to the front wall surface 5, the upper wall 6 connected to the upper portion of the front wall surface 5, and the lower surface of the outer edge of the upper wall 6 via the hinge 7. The handle wall 8 and the engaging portion 9 that is connected to the back side of the front wall surface 5 and engages with the engaging recess C are provided.
A handle hole 10 is formed at a predetermined position of the handle wall 8.

  The engaging portion 9 includes a base portion 11 provided on the back surface of the front wall surface 5 and a plurality of protrusion portions 12 disposed so as to protrude from the upper and lower sides and both side surfaces of the base portion 11.

The engaging recess C is formed by attaching the molded handle member B to the shoulder molding portion above the blow mold lateral rib 4 surface of the bottle A, and blow molding the preform softened by heating and softening. The preform is joined to the back surface of the front wall surface 5 of the member B, and the resin of the bottle A wraps around the back surface of the protrusion 12, and as shown in FIGS. An engagement recess C that engages with the outer surface of the joint portion 9 is formed.
At that time, a plurality of convex portions 13 that are engaged with the surface side of the protrusions 12 provided in the engaging portion 9 of the handle member B are formed in the engaging concave portion C by the wraparound of the resin of the bottle A.

Next, the effect of the bottle with a handle of this embodiment will be described.
The bottle with a handle of the present embodiment is formed by integrally forming the handle member B on the bottle A by insert molding, so that it can be firmly fixed and does not impair the beauty of the bottle.

  Further, since a plurality of protrusions 12 are provided on the upper and lower sides and both side surfaces of the base portion 11 of the engaging portion 9 of the handle member B, the handle member B is formed in the engaging recess C at the time of bottle molding. Can be firmly fixed to the bottle A.

  Since the handle wall 8 is connected to the upper wall 6 of the handle member B via the hinge 7, the direction of the handle wall 8 can be changed up and down with respect to the bottle A. It can be easily picked or hooked with a finger or the like in the handle hole 10, which is convenient for carrying the bottle.

  Furthermore, the handle member B only needs to be able to grip the handle wall 8 with fingers or the like or be hooked into the handle hole 10, so that the size can be reduced, and even a small bottle with a small internal capacity can be handled by the bottle A. The member B can be integrated and firmly fixed by insert molding.

Since the bottle with a handle of the present invention is only required to be able to be firmly fixed by integrating the handle member B to the bottle A by insert molding, the shape of the bottle may be any shape regardless of a circle, a rectangle, or a polygon.
In the embodiment, the base 11 on the back surface of the front wall surface 5 is a plate-like body, but a protruding piece provided with a locking portion at the tip from the front wall surface may be disposed.
Further, since a plurality of protrusions 12 are provided on the upper and lower sides and both side surfaces of the base portion 11 of the engaging portion 9 of the handle member B, the handle member B is formed in the engaging recess C at the time of bottle molding. Can be firmly fixed to the bottle A.

  Since the handle member B can be hooked with a finger or the like, it is possible to carry the bottle more conveniently by hooking and tying a strap or a neck hook. For example, the bottle can be hooked in a predetermined place.

The bottle with a handle of the present invention can have a simple and small structure of the handle member, and is integrally formed by insert-molding the handle member when molding a bottle molded with a PET resin having an internal volume of 500 ml or less. By doing so, the handle member can be fixed to a part of the shoulder portion of the bottle.
In addition, since the handle member can be easily molded, carried or hooked on any shape of the bottle, it can be widely used as a container for beverages, foods, fragrances, and medicines.
