Description

Technical Field [0001] The present invention relates to a handle structure of a polyethylene terephthalate container,

The present invention relates to a pet container handle structure, and more particularly, to a pet container handle structure which is biased in the outward direction from the center of the PET container and is formed into a long depression in the vertical direction with respect to the PET container, To prevent the slippage of the pet container handle.

Generally, PET container is made of polyethylene terephthalate as raw material, and it is convenient to produce and handle, is light and does not break, and is widely used for storing or transporting liquid contents.

These PET containers are largely composed of atmospheric pressure vessels (containers containing contents such as bottled water), pressure-resistant containers (containers containing contents containing carbonic acid), heat-resistant containers (containers containing contents such as juice) A container containing the contents contained therein), and the like.

Such PET containers can be manufactured variously according to the contents of the contents. In the case of a PET container which is often carried by the user and is to be consumed, a handle or the like is not provided because the container can be carried with one hand.

However, depending on the use of the contents, the capacity to be contained in the PET container is different. For example, in the case of a water bottle used in a home or a company, the capacity is usually 18.9 liters. Therefore, in order to place a water bottle on a water heater or a water purifier used by us, it is not only heavy enough to be handled by an adult male, but also has a problem that an adult man is very uncomfortable to handle because there is no handle on the outer surface of the water bottle.

In addition, large-volume products such as beverages and laundry detergents sold in large-sized marts are sold in 1.5 to 5 liter PET containers. Such a PET container capable of holding a capacity of 1.5 to 5 liters is not uncomfortable for an adult male to lift it up with two hands, but if it is intended to be carried by one hand, it is inconvenient for handling and transportation unless a separate handle is provided .

Therefore, it is general that a pet container capable of holding a capacity of 1.5 to 5 L is provided with a handle for convenient handling and transportation of the PET container. The handle provided in the PET container capable of containing the capacity of 1.5 to 5 L as described above is constructed separately from the PET container and is mounted on the PET container.

In the case of the handle having the structure to be mounted on the PET container after the separate manufacture, a separate assembly process for mounting the handle on the PET container is required, which not only reduces the productivity but also increases the production cost due to the additional production.

In addition, since the handle having the structure to be mounted on the PET container after being separately manufactured is easily damaged by a large load due to its structure, the outflow of the contents due to breakage of the PET container caused by breakage of the handle of the PET container, There is a problem of polluting the environment with economic loss.

Accordingly, in order to solve such a problem, the present inventors have developed and filed Korean Patent Registration Nos. 10-0418290 and 10-0479685. In the above-mentioned prior art patent, a core is installed inside a mold apparatus, and the PET container is stretched and recessed according to the movement of the core to form a handle that is symmetrical about the PET container.

As shown in Figs. 1 and 2, the handle formed as described above is formed with a handle 10, which is recessed in a side surface facing each other with respect to the PET container 1, respectively.

However, most of them are gripped with one hand of a PET container capable of holding a capacity of 1.5 to 5 liters. To this end, a handle is generally formed around the bottle main moving part.

Therefore, there is a disadvantage that the handle of the type described in Figs. 1 and 2 can not be used.

Generally, when the handle is located only on one side, most of them are manufactured separately from the PET container and then mounted on the PET container, so that it is troublesome to manufacture and the equipment cost is high.

In addition, PET containers having various designs have been developed to meet the aesthetic desires of consumers at present. However, the prior art has a drawback in that it can not satisfy the handle of a suitable shape for a PET container having various designs.

In addition, even if only one side of the handle to insert a finger to give enough force to hold, while holding the handle and the PET container integrally, the handle structure for holding and holding the pet container with only one hand is required.

As another technique, Japanese Patent Application Laid-Open No. 2007-153366 discloses a heat-resistant container, a heat-resistant container containing the content, and a method of manufacturing the heat-resistant container.

The above-described technique is a technique relating to manufacturing a container for manufacturing a container for improving the gripping property of the container structurally, and a 'groove' is formed in the grip portion to which the finger is contacted. However, However, it is structurally insufficient to prevent slippage, and there is a limit to sufficiently transfer the hand gripping force to the gripping portion.

In the container made of PET material, it is important that the grip part gripped by hand is designed not only for gripping but also for proper gripping with strong contact force and grip stability for sliding contact of fingers .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a structure of a pet container handle according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The pet container handle structure according to the present invention is constructed of a handle structure that improves gripping property by using fingers and hand grips, as well as improved contact and strong grip. And the finger is configured to have a stable gripping stability by preventing sliding contact.

The present invention is applied to a PET container 300 in which a container inlet portion 310 is formed on an upper portion and a handle is formed on one side of the PET container body 320.

The main portion is composed of a plurality of first finger insertion grooves 331-1 and a second finger insertion grooves 331-2 which are recessed inwardly corresponding to each other at one side of one side of the pet container body 320 to allow fingers to be drawn in, And a finger insertion recessed portion 331 made of a finger.

A handle 330 is formed on the outer surface of the outer side of the first finger insertion / recessed portion 331-1 and the second finger insertion / recessed portion 331-2.

In order to prevent slippage of the finger along the surfaces of the first and second finger insertion recessed and recessed portions 331-1 and 331-2, a plurality of inner protrusions 331-3 having a slope at the angle? 2 are formed.

Here, the inner protruding portion 331-3 is formed in the first finger inserting recessed portion 331-1 and the second finger inserting recessed portion 331-2, respectively, to prevent slippage when holding the finger in the recessed portion The inner protruding portion 331-3 is formed at an inclination angle? 2 inclined upward toward the top so that the force of the downward tilting of the finger due to the weight of the container body 320 It acts so that it does not slip well even if it works.

In addition, the handle 300 is configured to have an inclination angle θ1 in which the angle is gradually narrowed with respect to the horizontal axis x so as to be easily held by the hand. Here, the inclination angle θ1 given to the handle 300 induces the top of the container body 320 to be naturally inclined when the container body 320 is held by hand.

Also, the PET container 300 is formed by blow molding, and the handle 330 can be formed on one side of the formed PET container 300 through the handle forming means.

The outer surface of the handle 330 is formed with an outer protrusion 550 for preventing slippage when the PET container is held by hand.

In addition, the distance d between the two finger insertion recesses 331-1 and 331-2 is preferably 2 mm to 10 mm. If the distance is too far, the groove of the groove portion is increased, so it is difficult to hold the hand. On the contrary, if the distance is too narrow, it is difficult to sufficiently maintain the strength of the handle 330. The distance of 2mm ~ 10mm is the distance considering the thickness and strength of molding PET container using PET material.

In addition, the handle 330 may be formed as a first recessed portion and a second recessed portion formed by recessing the upper and lower ends inwardly compared to the central portion.

When the first recess and the second recess insert a finger into the inside of the handle 330 and hold the handle 330 by hand, the thumb and the index finger are caught by the first recess of the upper end side of the handle 330 and the ring finger. To prevent the sliding of the finger caught in the second recessed portion on the lower side side while increasing the grip force by the hand 330 to guide the handle 300 to be securely gripped.

The first and second recesses formed on the upper and lower portions of the handle 330 may be securely gripped by the handle 300 even when both the upper and lower portions are formed on the upper and lower ends or selectively formed on at least one of the upper and lower ends. .

As shown in Figs. 8 to 13, the handle 330 includes a leg-type beep grip which has an upper end and a lower end and is convex inward, a circular handle in which the upper end and the lower end are recessed and the stop is semicircular, An hourglass-shaped handle with a top and a bottom in a straight line shape, a stepped handle with an upper and a lower step and a stepped shape at the lower end, a glass catching handle with a curved upper end and a lower end narrowed shape, and a concave- As shown in FIG.

Further, as shown in Figs. 14 and 15, when the rectangular PET containers 1300 and 1400 are used, the grip 330 can be formed on one side of the side surface of the PET container.

16 and 17, in the rectangular PET containers 1500 and 1600, the handle 330 can be formed on one side of the edge of the PET container.

Further, as shown in Fig. 18, when the PET container 1700 is elliptical, the handle 330 can be formed on one side edge of the elliptical shape.

19, when the PET container 1800 is in the form of an isosceles rectangle longer than the longitudinal side, the handle 330 can be formed on the side of the longitudinal side.

A concrete embodiment of the pet container handle structure according to the embodiment of the present invention will be described as follows.

1st Example

3 is a perspective view of the PET container 300 according to the first embodiment of the present invention. Referring to FIG. 3, the PET container 300 includes a container inlet 310 and a body 320 formed integrally with the container inlet 310.

The body 320 may be formed of the same material as that of the body 320 by being embedded in one side of the body 320 so as to form two fingers insertion recessed portions 331, .

Polyethylene terephthalate (polyethylene terephthalate), which is a polyethylene resin, is used as the material of the PET container 300. Polyethylene terephthalate is excellent as a fiber, film, and beverage container, and is recently used as a container for electric and electronic fields such as conductive films and soft drinks.

Polyethylene terephthalate is superior in transparency to other plastic containers made of polyethylene or polypropylene, and has a very low gas permeability, so that the gas attached to the beverage is preserved as it is. The strength and stiffness of the polyethylene terephthalate is the largest among ordinary plastics, and the heat distortion temperature is about 240 ° C, which is excellent in heat resistance.

The PET container 300 itself made of polyethylene terephthalate may be formed by a blow molding method. In the blow molding technique, a preform (also referred to as a "preform" in some other terms) is placed on a mold for blow molding having a finished product molding space, and then the preform is injected into the preform at a predetermined pressure to heat the preform So as to be processed into a form provided in the blow molding die.

The blow molding is carried out under specific temperature and pressure conditions depending on the characteristics of the material. In the case of producing polyethylene terephthalate (PET) as the material, the preform molding temperature is about 85 to 120 DEG C, 40 bars.

The PET material has fluidity in the temperature range and the expansion of the material can be smoothly performed in the above-mentioned pressure range. The range of temperature and pressure depends on the material and properties of the preform. Such a blow molding technique is a well-known technique and will not be described further.

When the PET container 300 is formed, the handle 330 is then molded by the handle forming means. That is, in the case of the present invention, the process proceeds to two steps: a process of making the PET container 300 and a process of making the handle 330. The process of making the handle 330 is performed prior to cooling immediately after the PET container 300 is formed.

In the process of making the handle 330, the handle 300 is simply molded by compressing one side of the pet container 300 using a handle forming means (for example, may be a mechanized device).

When the two finger insertion recessed and recessed portions 331 are formed on the surface of the PET container 300, the grip 330 is formed by these two finger insertion recessed and recessed portions 331. Here, the finger insertion recessed portion 331 is used to allow the user to grip the PET container 300 by inserting a finger.

3 illustrates the pet container 300 as a cylindrical shape. However, the present invention is not limited thereto, but may be applied to a container having an elliptical shape, a square shape, a pentagonal shape, or the like.

The handle 330 is integrally formed. The knob 330 is formed so as to have a tilt angle? 1 at which the angle becomes narrower toward the upper part.

It is effective to grasp the fingers similar to the handle of the method in which the fingers are completely opened as the interval between the first finger insertion recessed portion 331-1 and the second finger insertion recessed portion 331-2 is narrower.

The distance d between the first finger insertion recess 331-1 and the second finger insertion recess 331-2 is preferably maintained at 2 to 10 mm.

FIG. 5 is an enlarged partial enlarged view of a portion P of the PET container 300 in FIG. Referring to FIG. 5, the outer surface of the handle 330 is formed with a protruding portion 500 of the PET bottle. The outer protrusion portion 500 of the pet bottle is provided for imparting a frictional force between the palm of the user and the grip 330 when the user grasps the grip 330 and prevents slippage.

20 to 21 are perspective views showing examples in which the handle structure according to the present invention is applied to an actual product. In other words, the PET container 300 has an elliptical shape with only one handle 330 formed on the upper right side of the PET container 300.

According to the present invention, the handle 330 is formed integrally with the pet container without taking the structure in which the handle 330 is separately formed from the PET container and then mounted on the PET container.

The present invention is relatively simply molded through a conventional blow molding method in which the knob 330 can be integrally molded with the container body.

Therefore, in designing the various shapes of the handle 330 under the blow molding condition, the manufacturing conditions including the mold design are difficult and the constraints are large. Therefore, the shape that stably maintains the gripping performance of the handle 330 is more specific Shape design is required.

The present invention is configured such that the shape of the handle 330 can be gripped by a strong hand when gripping the hand and that the shape of the handle 330 in contact with the finger or palm does not slip well.

When the thumb is inserted into the first finger insertion recessed groove portion 331-1 and the remaining fingers are inserted into the second finger insertion recessed portion 331-2 at the position where the handle 330 is held by the right hand, and the palm is simultaneously brought into close contact with the protruding portion 550 of the PET container grip.

Accordingly, the user can grasp the pet container 300 with a sufficient force, and can grip the pet container 300 in a safe state in which the inner protruding portion 331-3 and the outer protruding portion 550 are simultaneously brought into contact with the fingers and the hand brakes, 330).

In addition, the handle 330 has a first recessed portion and a second recessed portion formed by recessing the upper and lower ends of the upper portion and the lower portion concave inwardly, so that the first recessed portion and the second recessed portion move the fingers into the handle 330. When inserting and holding the handle 330 by hand, the thumb and index finger are caught by the first recess of the upper side of the handle 330, and the lower finger portion of the lower finger is caught by the lower recess of the second side to prevent the sliding of the finger. At the same time, the force to hold the handle 330 by hand is increased through the recess to induce the handle 300 to be safely gripped.

Here, the first and second recesses formed on the upper and lower ends of the handle 330 may increase the force to grip the handle 300 even if both the upper and lower ends are formed at least, or selectively formed on at least one of the upper and lower ends. This can improve the grip safety of the handle.

As described above, the present invention has been described with reference to the drawings and specification, with reference to an embodiment of the invention, but it is an example. Those skilled in the art can make various modifications and equivalent implementations.
