Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an improvement of a container with a handle.

(Prior Art) In recent years, many large-sized containers such as bottles have been used, or containers with relatively small necks compared to the bottle body are preferred for design purposes. Considering the ease of handling these containers, it is desirable to have a handle.

A large number and variety of such containers with handles have been proposed, including those in which a separately molded handle is attached to the neck of the container by screw fitting, and those in which the handle is integrally molded with the container.

(Problem to be solved by the invention) As an example, the inside of the mounting ring provided integrally at the base of the handle has a threaded structure, and this is inserted into the threaded part formed on the outside of the bottle neck and screwed together. There is something.

There are also many containers with handles in which the semicircular arc-shaped attachment part at the base of the handle fits into the neck of the container (for example, Japanese Utility Model Application No. 188844/1988, Japanese Utility Model Application No. 60/1983).
154230 etc.).

However, () the screw-fit type requires several relative rotations when attaching the handle; () both types also have design problems because it is difficult to position the handle relative to a specific bottle display label; () ) If the bottle has an asymmetrical part, the arrangement of the handle is not consistent. () The engagement between the two is not firm and the container tends to wobble in the handle support position. These problems can be solved by molding the handle as one piece in advance. However, on the other hand, such a container with an integrated handle inevitably increases the cost of molding, and it is difficult to mold so-called PET bottles, which have been in high demand in recent years, due to material restrictions. There was a problem.

The present invention aims to solve this problem.

(Means for Solving the Problems) The present invention provides a container having a flange annularly protruding outward from the neck and an engagement structure on the flange, a handle portion and an attachment portion to the flange portion, which are integrally molded. and a handle of substantially the same shape, in which the mounting portion clamps the flange along a desired arc length portion of the flange that includes the engagement structure, while opening the flange along the arc. wall and
A flexible piece extending from the handle portion facing the open side to at least the flange engaging structure at a position where the flange is held by the retaining wall, and engaging the flange engaging structure at the same position provided on the flexible piece. The present invention is a container with a handle, which is provided with another engaging structure, and an arcuate support wall portion that is brought into contact with the container neck portion along the opening portion below the flange.

(Function) As is clear from the above structure, the present invention has an engaging portion between the handle and the container flange, in which the container side is engaged with a part of the flange that generally exists in this type of container by means of an engaging groove or a hole. Since the engagement structure is provided with another engagement structure formed by an engagement protrusion on the handle side which will be described in detail later, the handle position is determined by the engagement hole position, and the engagement structure is engaged with the engagement structure. At the same time, the desired length of the flange is supported by the retaining wall, and the arcuate wall abuts against the neck so that both are firmly held.Furthermore, since the container and handle are separate, the above-mentioned restrictions due to the materials used for molding are not imposed. It has the following effects.

(Example) This invention will be explained in detail below with reference to an example shown in the drawings. In Fig. 1, (1) is an integrally molded container such as a plastic bottle, a cap 2 is attached to the top part 1a, a normal flange 1c is formed in the neck part 1b, and a desired part of the flange 1c is formed. is widened, and an engagement hole 1d is formed in that part. In the illustrated example, this engagement hole 1d is a long hole.

Next, a handle 3 is attached to the container 1, and the handle 3 is formed by integrally molding a handle portion 3a along the upper half of the container and an attachment portion 3b to the flange 1c. Next, as shown in FIG. 2, FIG. 3, and FIG. ), the retaining wall 3d has a substantially same shape and has an open portion 3c in the semicircular arc direction, sandwiching the flange therebetween.

The flange retaining wall 3d has an upper wall 3e projecting along a part of the arc, which cooperates with an arcuate support wall to be described later to sandwich the flange 1c from above and below.

Next, at the position where the flange 1c is held by the holding wall 3d, the handle portion 3a facing the opening portion 3c is
A flexible piece 3f extending from to at least the engaging groove 1d is provided to protrude in the direction of the opening 3c, and a protrusion 3g that engages with the engaging hole 1d is formed at the same position on the flexible piece 3f. ing.

The position of the protrusion of this flexible piece 3f is determined by the position of the projection on the upper wall 3e.
This is determined based on the upper surface support position of the flange 1c and the positional relationship that does not cause any hindrance when the flange 1c is fitted from the open portion 3c.

Also, the protrusion length is the same as that of flange 1 when mating as described above.
c and within the range that maintains the fitted state.

Next, in the above-mentioned fitting relationship, the retaining wall 3d
Furthermore, an arcuate support wall portion 3h extending integrally with the opening portion 3c below the flange 1c and in contact with the container neck portion 1b is formed in a substantially semicircular arc shape.

The handle 3 configured as described above has the opening portion 3c connected to the flange 1c of the engagement hole 1d portion of the container 1.
(position in Figure 2), and then attach flange 1 as is.
Fit into c.

The retaining wall 3d holds the flange 1c, and the protrusion 3g on the flexible piece 3f fits into the engaging hole 1d. In this state, the arcuate support wall 3h abuts the container neck 1b at the lower part of the flange 1c. By supporting this, the fitting and installation of the two is completed (Figures 5 and 6).

In this invention, a wide range of modifications can be considered for the engagement structure of the handle portion with the above-mentioned engagement hole 1d of the container flange. For example, the engagement hole 1d may be a simple circle, or it may be a groove, or the flange 1c may be provided with a protrusion 1d', and the flexible piece 3f may be provided with an engagement hole 3g'.
Each may be engaged as an engagement structure (seventh
figure).

Although not shown in the drawings, the present invention can be modified in the following manner.

() Change the arc length of the above-mentioned handle attachment part within a range that does not interfere with its fitting and support structure.

() Changes such as changing the installation of the above-mentioned engagement holes and projections upward and downward.

(Effect of the invention) Since the present invention has the above configuration, the container side of the above-mentioned engaging part is provided with an engaging structure such as an engaging hole in a part of the flange that generally exists in this type of container. Since the other engagement structure of the arcuate attachment part of the handle is fitted into the engagement structure, the handle position is determined by the engagement hole position, and since the container and the handle are separate, there is no need for molding. Not subject to the above restrictions due to the materials used,
Furthermore, since the container neck is supported by the arcuate wall such as the above-mentioned retaining wall, the above-mentioned problems can be substantially eliminated, such as the support is solid.
