BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handle for mounting a thin plastic bottle having a body portion in a concave portion of the bottle body portion, and a bottle provided with the handle.

[0002]

The handle of a packaging bottle, which is widely used as a PET (polyethylene terephthalate) bottle, may be attached by an insert or later by fitting the bottle into a molded bottle.

[0003] As a method of fitting, a support arm protruding up and down of a grip portion is inserted into upper and lower walls of a concave portion, and a distal end portion of the support arm is pushed upward by a plate member to be expanded, so that an outer surface of the distal end portion is formed. A method in which the projection is fitted into the depression formed in the upper and lower walls, and the state is supported by the plate member and fixed, and a state where the projection member is integrally formed at the tip of the upper support arm, and the projection member is engaged with the projection member. There is a method of performing matching and maintenance.

In these methods, since the support arms at the upper and lower portions are pushed and spread in the concave portions, a large finger pressure is required for fitting, and after the fitting, the strut member prevents the retaining members from coming off. There is a problem that it cannot be easily removed at home when the bottle is discarded because it fits deeply with the projection.
In some cases, the grip portion is bent and attached, but in this case, since a large external force is required for the bending, a special jig is required for attaching and detaching the handle.

The present invention has been conceived in order to solve the above-mentioned conventional problems, and has as its object to provide a handle body capable of bending a handle and a lock member for preventing the handle body from being bent. It is an object of the present invention to provide a new handle and a bottle with a handle which can be attached and fixed to the recess of the bottle body part from the outside, and can be easily removed at the time of disposal.

[0006]

A handle according to the present invention for the above object has a pair of support arms in the same direction, which have upper and lower inner surfaces of a vertically long grip portion, and a pair of support arms projecting from the outer surface of a distal end portion. The handle comprises a handle body provided with a lateral groove at the center of the handle so as to allow the handle to be bent inward, and a lock member that fits with the handle to prevent bending.

The lock member includes a head portion which is located at the upper end of the grip portion and abuts against the wall surface of the bottle, and a sheath portion which is long and integrally formed below the head portion, and the sheath portion is a grip portion. The inner surface of the grip is covered with three side surfaces, and the inner surfaces of both sides are fitted with vertical grooves provided on both side surfaces of the grip portion to have a ridge for preventing bending of the grip portion.

Further, the handle has a handle body having a vertical hole therein, and a lower portion of a head portion which is located at an upper end of the grip portion and abuts against the bottle wall surface and has the same flat cross-sectional shape as the vertical hole. It comprises a lock member having a formed insertion portion, and the insertion portion has a length whose lower end is located at least below the lateral groove.

In the bottle with handle of the present invention, a pair of support arms in the same direction protruding above and below the inner surface of the vertically long grip portion are provided in a recess formed on the side surface of the body of the bottle body. Bend the groove from the side groove of the support arm and press the handle inward to fit the protrusions on the outer surface of the tip of the support arm into the recesses on the upper and lower wall surfaces of the recess, and contact the support arm with the upper and lower wall surfaces. The handle is straightened in contact with the handle, and the handle is fixed to the bottle body by preventing the grip from being bent by fitting the lock member.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the drawings, reference numeral 1 denotes a handle main body, and 2 denotes a lock member of the handle main body 1, which is formed by injection molding of the same or different thermoplastic resin. Reference numeral 3 denotes a thin bottle body made of polyester, polycarbonate, or the like.

The handle main body 1 has a vertically long thick plate-shaped grip portion 12 provided with fitting vertical grooves 11 on both sides, and a pair of support arms 13 and 14 integrally formed in the upper and lower directions in the same direction. The projections 13a and 14a for locking are projected from the outer surfaces of the distal ends of the support arms 13 and 14.

At the center of the grip portion 12, a lateral groove 15 is cut in a V shape inward from the outer surface. It is formed so that it can be bent inward from.

The lock member 2 is located at the upper end of the grip member 12 and is integrally formed with a head portion 21 which is in contact with the wall surface of the bottle main body 3 so as to be biased outward to the lower side and elongated downward. And a sheath 22. The sheath portion 22 covers three sides except the inner side surface of the grip portion, and is fitted to the vertical grooves 11 provided on both side surfaces of the grip portion 12 on both inner surfaces,
A ridge 23 is provided to prevent the grip from being bent.

A recess 31 for attaching a handle is formed in the body of the bottle body 3, and upper and lower walls 32,
Depressions 32a and 33a for engagement are formed in 33.

FIG. 1 shows a state in which the handle by the handle body 1 and the lock member 2 is attached to the recess 31. The handle 12 is bent inward to support the upper and lower support arms 13,1.
4 shows a state in which the support arms 13 and 14 are inserted into recesses 31 formed in the thin body in this state.

In this state, when the bent central portion of the grip portion 12 is pushed inward by the thumb as shown by an arrow, the tips of the support arms 13 and 14 abut against the vertical wall 34 of the recess 31, and The protrusions 13a and 14a on the outer surface of the distal end are moved upward and downward by the reaction force so that
The recesses 32a, 33a formed in the second and the third 33 enter and engage with each other, and the grip portion 12 is positioned straight. Further, the support arms 13 and 14 abut against the upper and lower wall surfaces, and the grip portion 12 is temporarily fixed.

While supporting this state with the thumb, the sheath 22 of the lock member 2 is fitted from the upper end of the grip portion 12 and pressed firmly until the lower edge of the head portion 21 contacts the upper end of the grip portion 12. When it is fitted, the three sides except the inside of the grip portion 12 are covered with the sheath portion 22 and the longitudinal grooves 11
And the ridge 23 are fitted to prevent the grip 12 from being bent, and the handle is securely fixed to the recess 31 of the bottle main body 3 as shown in FIG. This fixation is maintained by the engagement of the lock member 2, and unless the handle is strongly pulled upward from the grip portion 12 and pulled out, the handle will not come off and fall off even if it is inverted.

Further, a corner is formed on the upper surface of the upper support arm 13 along the outer edge shape of the upper wall 32 of the recess 31 by the contact of the head portion 21 with the bottle wall surface, and the outer edge of the upper wall is clamped by the corner. Therefore, even when the bottle body 3 is inclined and the contents are poured, the handle is stable and easy to handle.

FIG. 6 shows another embodiment of the handle.
In addition to the vertical grooves 11 on both sides of the grip portion 12 of the above-described embodiment, a vertical groove 15 having a V-shaped cross section is formed on the outer surface, and a convex line 25 that fits into the vertical groove 15 is provided with a sheath of the lock member 2. It is provided on the inner surface of the portion 22, and the connection between the handle body 1 and the lock member 2 is made more precise by fitting the three vertical grooves and the ridges to prevent the bottle body 3 from dropping out of the recess 31. .

FIGS. 7 and 8 show an embodiment in which a pin or the like can be inserted and fixed. A rectangular vertical hole 17 is formed in the center of the grip portion 12 from the upper end to the lower end, while a lock is formed. The member 2 is formed from the head portion 21 and an insertion portion 26 having the same cross section as the vertical hole 17 integrally formed below the head portion 21, and the insertion portion 26 is inserted into the vertical hole 17 from above, and at least the lower end is formed from the horizontal groove 15. It is made of a material which can be forcibly inserted and fixed to a position below.

In the present invention having the above structure, the grip is bent, the upper and lower support arms are inserted into the lower portions of the upper and lower walls of the recess of the bottle body, and the grip is pushed in, whereby the protrusion at the tip of the support arm is formed. The upper and lower walls can be engaged with the upper and lower walls, and the support arms can be in contact with the upper and lower walls. In this state, the handle can be fixed to the bottle body simply by fitting the lock member to the grip portion. It will be easier. In addition, the mating part is difficult to remove due to frictional resistance between plastics. When unnecessary, simply pulling the head and pulling out the lock member, the handle body can be easily removed from the recess, so it takes a great deal of force to remove the handle. In addition, there is an advantage that the handle can be easily removed at home and the bottle can be discarded.
