Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a blow-molded container with a handle mainly used as a pot for beverages.

(Prior Art) Conventionally, the handle of this type of container is blow-molded integrally with the container body when the container body made of synthetic resin is blow-molded.

(Problems to be solved by the invention) The conventional handle blow-molded together with the body is tubular and both ends of the grip portion are bent toward the body to form a hollow curved portion that is continuous with the body, and has a continuous shape with the body. The device can be integrated with the body so that it can be handled sufficiently, and its own strength is also sufficient.

By the way, the conventional handle is hollow and communicates with the body.
For this reason, during the handling of the body, drinks such as water, tea, and coffee in the body often enter the handle. However, since the cleaning does not reach the inside of the handle, water stains, tea stains, coffee stains, etc. tend to adhere and gradually deposit, and they appear as shadows and discoloration on the outside. Make people feel uncomfortable and unclean.

Therefore, it is conceivable to separately form the handle, which was conventionally formed integrally with the blow-molded body, and attach it later. However, the body is a lightweight and low-cost synthetic resin blow-molded product, and it is difficult to attach a separate handle without impairing its characteristics and sealing properties. In addition, if you simply handle both sides of the handle by simply imitating the conventional handle form and attaching both ends of the handle to the body, the rigidity of the body wall is weak and the handle will not be stable when handling a heavy body containing drinks. It may wobble.

(Means for Solving Problems) In order to solve the above-mentioned problems, the present invention has a rectangular parallelepiped as a basic shape and its oblique corners are cut off, and the cut-off part is substantially L-shaped in a side view. And a ring-shaped handle attached to the substantially L-shaped cut portion. The horizontal portion is provided on the handle attachment surface of the L-shaped handle of the body. From the horizontal part to the vertical part, the concave part is integrally formed from the horizontal part to the vertical part on the mounting side part of the handle, and the handle is inserted into the concave part with the protruding part and the concave part fitted together. It is characterized by being fixedly attached to the body at both ends of the groove.

(Operation) The handle mounting surface is provided on the cut-out portion of the body and has a substantially horizontal horizontal portion and a vertical portion substantially vertical thereto, and a ridge is provided across these two surfaces. In the horizontal part that is in contact with the horizontal part and the vertical part that is in contact with the vertical surface, a groove corresponding to the protrusion is formed over two surfaces, and the body and the handle are fitted in a state where both are fitted. Fasten.

Therefore, since the handle is attached to the body in a wide area and is attached to the two surfaces of the substantially horizontal surface and the substantially vertical surface, the handle receives a wide load on the attachment portion with the body. It can be received on and around the contact surface portion, and can be further received on two surfaces, a horizontal surface and a vertical surface. Therefore, when liquid enters the body and is very heavy, a large moment acts in the direction in which the body separates from the handle on the substantially vertical surface of the handle and the attachment part of the body, and the handle and body are fixed. Although a large shearing force is applied to the fastening portion such as the locking pin, in the present invention, the moment can be counteracted by the pressure contact state on the substantially horizontal surface with respect to the moment, that is, the bottom surface of the handle. Since it is possible to prevent the handle from separating from the body on the vertical surface, a large shearing force is not applied to the fastening portion, and the handle is an annular body, and the pressing force and force acting on it are It has a structure that can easily withstand tensile force, so it is easy to stabilize the handle and body.

As described above, the fitting portion of the body and the handle is structured to be fixed at both end positions of the concave groove in a state in which the projecting ridge and the concave groove are fitted to each other, so that they are firmly fixed to each other. It is possible to reliably prevent wearing and swinging to the left and right, and the fitting portion of the handle mounting portion of the body with the handle improves the rigidity of the handle mounting portion of the body and its surroundings, The stability of the handle and the body due to the wide contact surface can be further improved. In addition, the wide contact surface can increase the fitting area between the mounting side portion and the body for the fastening, enhances the coupling strength and stability of the handle and the body, and exerts a force in the left and right directions. Can also endure. Therefore, the fitting portion of the handle mounting portion of the body with the mounting side portion is sufficient to be formed during blow molding of the body.

(Embodiment) A first embodiment of the present invention shown in FIGS. 1 to 5 will be described. The blow-molded synthetic resin container 1 is as follows.
As shown in Figs. 1 and 2, a vertically long container having a rectangular cross section, in which a part of the upper half is cut off from one side of each of the narrow side surfaces, that is, the basic shape is a rectangular parallelepiped, The upper corner portion is cut off, and the cut portion is cut into a substantially L shape in a side view, and a separately molded handle 3 made of synthetic resin is attached to the cut portion 2. A container port 4 is provided at the upper end of the body 1.
(FIG. 2) is formed in a short tubular shape, and a spout 5 made of synthetic resin is screwed into it. The spout 5 has a mounting part 5a that is screwed into the container port 4, and a liquid injection guide peripheral wall 5c having a beak-shaped part 5b that extends to one side is integrally formed on the upper part of the mounting part 5a. A plug body 6 screwed around the circumference opens and closes an opening 5d of the spout 5 communicating with the container port 4.

The handle 3 includes a grip portion 3a and a mounting side portion 3b facing the grip portion 3a.
And are formed as a ring-shaped integrally molded product having a substantially same length and continuous in a ring shape, and are formed in a shape having an inclination corresponding to the cut portion 2 of the body 1 as a whole. As a result, the mounting side portion 3b becomes the cut portion 2
Has a mounting contact surface 11 aligned with the grip portion 3a
It has an outer shape that is continuous with the top surface and the narrow side surface in a substantially flush state.

The cutout portion 2 is cut into a substantially L shape in a side view and has a substantially horizontal horizontal portion and a vertical portion substantially vertical to this, and the center portion in the width direction thereof is used as the handle mounting portion 21. 21 is formed with a protrusion 22 that fits with the mounting side portion 3b over substantially the entire length as a blow-molded portion that is protruded to the outer surface of the body 1. At both ends of the protrusion 22, mounting projection pieces 23 for fitting the mounting side portion 3b and fixing the mounting side portion 3b are also formed by blow molding. The mounting projection 23 is a small projection that is formed in a solid state and can be blow-molded.

Here, the ridges 22 form rib-shaped protrusions that extend over almost the entire handle mounting portion 21 to reinforce the handle mounting portion (fitting portion) 21 and its vicinity of the body 1 to enhance rigidity, and The stability of the mounting projection (fitting portion) 23 on the outer surface of the body 1 is enhanced. The cutting portion 2 itself having the handle mounting portion 21 of the body 1 also has a cutting line bent in a substantially L shape in side view, and is slightly narrow in width and slightly curved in the width direction, so that the rigidity is slightly high. Has become.

As a result, the handle attachment portion 21 of the body 1 and the surrounding portion include the attachment protrusion 23 as the attachment portion of the handle 3 and have sufficient rigidity.

The mounting contact surface 11 of the mounting side portion 3b of the handle 3 has a horizontal portion and a vertical portion, and the recessed groove (fitting portion) 12 as shown in FIGS. 1 and 3 to 5 has the horizontal portion. Further, it is formed so as to extend vertically, and is fitted to the projection 22 and the attachment projection 23. As for the handle 3, the mounting side portion 3b is attached to the ridge 22
And the mounting projection piece 23 is covered with the concave groove 12 so as to fit, and the mounting side portion is provided around the projection 22 and the mounting projection piece 23.
The mounting contact surface 11 of 3b is in close contact with the outer surface of the handle mounting portion 21. In this state, the mounting side portion 3b is firmly fixed to the handle mounting portion 21 of the body 1 at the two upper and lower positions by inserting the spring pin 14 inserted from the side mounting hole 13 into the mounting hole 24 of the mounting projection 23. The handle 3 is attached and stabilizes on the outer surface of the body 1 by adding the function of positioning and posture by fitting the concave groove 12 with the protrusion 22 and the attaching projection 23 in the entire attaching side portion 3b.

With the mounting structure of the handle 3 as described above, the handle 3 can be firmly attached to the body 1, and in addition, the load received from the body 1 by the handle 3 is received on two surfaces, a horizontal surface and a vertical surface. Therefore, hold the grip portion 3a of the handle 3 and carry the container 1 containing the drink,
Or when tilting or injecting liquid, body 1
And the handles 3 are stable with respect to each other and do not wobble. Moreover, the mounting projection 23 is a solid portion outside the body 1, and even if the handle 3 is mounted in the mounting hole 13 through the spring pin 14, the sealing property of the body 1 is not impaired. Also, the fitting part with the protrusion 22 and the mounting projection 23 is the mounting side part 3b.
Since it covers and hides, it does not damage the appearance,
It is possible to increase various fitting forms and handle fastening parts without impairing the external appearance.

In the second embodiment of the present invention shown in FIG. 6, the body 1 is horizontally long, and the cutout 2 for attaching the handle 3 is the body 1.
It is different from the first embodiment in that the handle 3 is provided on the top surface and the handle 3 is laterally attached to the cutout portion 2. The other points are the same as those in the first embodiment, and the description thereof will be omitted.

(Effect of the Invention) According to the present invention, since it has the above-described configuration and use, it is possible to attach a separate handle firmly and stably to a blow-molded synthetic resin container at the same time.
The load of the body on the handle can be divided into horizontal and vertical planes.
Since it can be received on one side, with the fastenings provided on both ends of the concave groove, the grip part of the handle is grasped and the heavy body containing drinks is wobbled no matter how it is handled. There is no such thing. Further, the structure is simple and can be provided easily and inexpensively, and is not particularly heavy.
