The present invention improves the handle attachment structure of PET bottles used by storing cooking oil, soy sauce, and other general beverages, and spilling them as needed, so that the handle can be firmly fixed to the container without flow. It is designed to provide safety when moving and to provide more stability when spilling contents in a container.

In general, a PET bottle as a liquid container is relatively thin in thickness, and when the handle is integrally formed on the container itself, the handle cannot fully support the weight of the container in which the liquid is embedded. Since manufacturing costs, such as mold cost to form a large amount of time is required, the handle is injection molded with a rigid resin, such as a separate FRT, and then adopts a method of assembling the handle to the outer edge of the container.

PET bottle having a handle coupling method as described above has a number of coupling structures have been devised as shown in FIG.

That is, in the manner as shown in FIG. 1 (a), in order to facilitate assembly of the container 101 and the handle 102, the outer circumferential surface of the upper neck portion of the container 101 and the inner circumferential surface of the connection ring 103 of the handle 102 are uneven. Partial portion 104 is formed radially at equal intervals to insert the connecting ring 103 of the handle 102 into the neck portion and then rotate the handle 102 slightly so that the uneven portion 104 can be caught in the vertical direction. The main surface handle 102 is to be assembled while being interlocked with the concave-convex portion 104 of the connection ring 103, by rotating the handle 102 to the width of the container 101 after fitting downwards It is obvious that the structure to be coupled to provide ease of coupling, but the handle 102 is often rotated randomly after coupling, which has the disadvantage that the stability is not ensured when the container 101 is carried or the contents spilled, the handle 102 ), When the container 101 rotates the handle 102 From out there was such a problem that discard discarded disrepair dumped the contents or packaging (101).

And the coupling method of the container 101 and the handle 102 as shown in Figure 1 (b) forms a coupling groove 105 of a predetermined size on one side of the outer peripheral surface of the neck portion of the container 101, the coupling groove 105 Forming a coupling protrusion 106 that can be fitted to the inner periphery of the handle 102 has a configuration that can be coupled to each other by interference fit, but this is a container 101, the coupling groove 105 having a large standard Although there is no big problem in forming, forming the engaging protrusion 106 on the inner edge of the handle 102 complicates the structure of the mold, and the size of the engaging protrusion 106 matches the engaging recess 105. In the case of the dimensions, there is a hassle to use the core, so the protrusion width of the actual coupling protrusion 106 is enough to be slightly caught in the coupling groove 105, so that the handle (e.g. The engaging protrusion 106 of the 102 from the engaging groove 105 of the container 101 In many cases to ride, it will also had problems of stability and binding gender use.

In order to solve the problems of the container and the handle attachment structure in the conventional PET bottle, the present applicant has previously announced the application of the handle attachment structure of the PET bottle (notification number: 95-3566). Summarizing these preliminary descriptions; The handle 102 is provided with a cutout 107, a recess hole 108, and a single indentation 109, and the handle 101 is formed with a single indent 111 having a locking protrusion 110 in the main body of the container 101. ) Is inserted into the container 101 by the fixing pin 112 of the handle 102 and the locking protrusion 110 and the projection 113 of the container 101 to be firmly fixed by the handle 102 ) Is very easy to fasten and detach, and the handle 102 is securely fastened to increase the convenience of use, but as shown, the structure of the container 101 and the handle 102 is complicated As a result, the mold cost is consumed a lot, and the process of combining the fixing pins 113 is additionally added, resulting in the inconvenience of the process. The present invention eliminates the problems of the conventional PET bottle handle attachment structure as described above. PET bottle handle having the following characteristics to To provide an attachment structure.

In other words, the container and handle structure of the PET bottle is extremely simple but extremely easy to combine, and maximizes the stability and bonding force when using the combination to improve the overall convenience in use, and the present invention will be described in detail with the accompanying drawings below. It is as follows.

FIG. 2 is an exploded perspective view of the present invention, and FIG. 3 is a cross-sectional view of a bonded state. In the PET bottle 1, which is generally capable of storing and carrying various liquids, the outer edge of the upper end of the container 2 of the PET bottle 1 is shown. The upper part of the upper round part of the coupling pipe part 4 is formed on the handle 3 and the coupling pipe part 4 in a predetermined width, so as to protrude upward stopper 5 having a stopping jaw 5 'at the lower end thereof. The container 2 is formed at the lower end of the coupling pipe 4 at the same height h as the connection ring 6 of the handle 3 from the locking jaw 5 '. To be molded.

The stopper 5 having the locking jaw 5 'may be formed in one or more (three in the example shown) as shown in FIG. 2A, and in FIG. 2B as necessary. As shown, it may be formed of a stopper 5 having an annular locking jaw 5 '.

The stopper 8 is formed at the coupling pipe portion 4 at one side of the round jaw 7 so as to protrude a stopper 8 that prevents the left and right flow of the handle 3, and the stopper 8 is connected to the handle 3. The stopper hole (9) formed inside the ring (6) is to be coupled to each other stopping.

PET bottle (1) of the present invention can be configured as described above, the structure of the container (2) and the handle (3) is extremely simple, but easy to combine and excellent coupling force can maximize the use stability and durability of the product, etc. As it is, look at the method of coupling the container 2 and the handle 3; When the connection ring 6 portion of the handle 3 is placed in the upper end of the container 2, the inner diameter of the connection ring 6 is positioned on the top of the stopper 5 formed above the container 1 coupling pipe part 4. When the handle 3 is pressed downward (by using manual or separate mechanism) in the above position, the inner edge of the connection ring 6 of the handle 3 is coupled along the round part of the stopper 5. The upper end of the connection ring 6 is coupled to the lower locking jaw 5 'of the stopper 5 while being lowered under the pipe part 4, and the stopper hole 9 formed at the inner edge of the connection ring 6 is It is coupled to the flow stop by fitting the lower stopper (8) of the coupling pipe (4). And the lower end of the coupling pipe (4) is formed with a round jaw (7) is the connection ring 6 is to play a role in determining the bottom coupling position to the coupling pipe (4).

This coupling state is a state in which the upper end of the connection ring 6 of the handle 3 is prevented from being separated upward by the locking step 5 'of the stopper 5 in a state of being fitted to the coupling pipe portion 4, The lower end of the connection ring 6 is prevented from being separated downward by the lower end 7 of the coupling pipe part 4, and at the same time, the stopper hole 9 is formed such that the lower stopper 8 is recessed in the inner edge of the connection ring 6. ), The handle 3 is prevented from rotating in the left and right directions so that the handle 3 can be firmly coupled to the container 2.

And the present invention, in particular, the coupling structure of the container (2) and the handle (3) is extremely simple, but the bonding force as described above can be provided with excellent advantages in manufacturing cost and process, etc., the combination is also simple It is possible to combine the two simply by the interference type and can be provided with operational advantages.

In the following description of the utility model registration, which will be described later, the technology to be protected in the present invention will be described, but the basic construction is the same, even in the case of similar modifications that can be easily changed by those skilled in the art. The same thing as the present invention.
