Description

Grease filling container for refill {GREASE CHARGING VESSEL FOR REFILL}

The present invention relates to a grease filling container for refilling, and more specifically, an inner skin of a vinyl resin is integrally heat-sealed to an outer shell made of a thin metal plate so as to prevent deterioration due to sunlight. It relates to a refilling grease filling container that maintains cleanliness by not leaving residual grease, and maintains the quality of grease by preventing residual grease and refilled grease from being mixed.

In general, grease having a high viscosity is injected into moving parts such as vehicles or mechanical equipment such as automobiles and heavy equipment to reduce friction and wear between parts, so that smooth operation can be achieved and durability can be improved.

Typically, in order to inject grease into operating parts such as vehicles or mechanical equipment, grease is directly injected wherever lubrication is required by using a grease lubricator or an injection gun.

Conventionally, a method of injecting grease using a grease lubricator is mainly used, and most of these grease lubricators are performed manually, but by opening the nozzle tip of the grease lubricator into the inside of a movable can container containing a large amount of grease. With the front end of the cylinder body inserted, the piston at the rear end of the cylinder is pulled to inhale and charge grease into the cylinder body.

Then, the opening of the front end of the cylinder is closed and the actuating handle is operated to inject grease where necessary using a nozzle.

Since the grease on the outer periphery of the cylinder body must be wiped off one by one during grease charging, there are problems such as unnecessary consumption of grease and grease staining on the hands of workers, making the work of filling grease very inefficient.

In addition, if residual grease remains in the cylinder of the grease lubricator, there is a problem that the residual grease and refilled grease are mixed and the quality of the grease cannot be maintained.

In order to improve this, a “packaging container for filling grease of a grease lubricator (Korea Patent Publication No. 2015-0145045)” has been disclosed. Such a packaging container is provided with a tensile handle, making it inconvenient to move and store. There was a problem in that a grease lubricator was required and a new grease lubricator had to be purchased.

In addition, since it is made of a soft vinyl material, there is a problem in that the grease may be deteriorated by sunlight and may be easily damaged by external force.

In addition, since it is made of a soft vinyl material, there is a problem in that the grease flows back into the cylinder by the discharge pressure of the grease lubricator, so there is a problem that the residual grease remains in the cylinder after use.

First, as shown in Figs. 1 to 4, the present invention is made by heat-sealing the inner skin 12 of a vinyl resin integrally to the shell 11 made of a thin metal plate so as to prevent deterioration due to sunlight, It relates to a refilling grease filling container 100 that prevents residual grease from remaining inside the grease gun 200 during refilling to maintain cleanliness, as well as prevents mixing of residual grease and refilled grease to maintain the quality of the grease. .

The refillable grease filling container 100 of the present invention is largely composed of three parts, which include a container body 10, a primary sealing part 20, a secondary sealing part 30, and a backflow prevention part 13. Is composed.

The container body 10 is a form in which the inner skin 12 of a vinyl resin is integrally fused to an outer shell 11 made of a thin metal plate with both sides open.

Here, the outer shell 11 is to prevent the projection of sunlight, and the inner shell 12 is to prevent oil leakage of grease and to prevent brittleness of the outer shell 11 made of a thin metal plate.

On the other hand, in another embodiment, the inner skin 12 may be formed by heat-sealing both surfaces to further reinforce the brittleness of the outer skin 11.

The primary sealing part 20 is configured by thermally fused inner skins 12 on both sides of the container body 10 to prevent leakage of the grease 60 accommodated in the container body 10.

The secondary sealing part 30 is processed to bundle the primary sealing part 20 of the container body 10 into a sausage type.

The secondary sealing part 30 functions to prevent the first sealing part 20 from being damaged by internal pressure.

In addition, the secondary sealing part 30 additionally configures the filling container 100 in a sausage-type shape to make the appearance beautiful, as well as reducing the area in which the bundled secondary sealing part 30 is cut. It also functions to facilitate easy incision with tools such as bars and scissors.

The backflow prevention part 13 is formed in an annular "ring" shape of an elastic material on both sides of the container body 10, and more specifically, may be made of any one of latex, rubber, and silicone.

The backflow prevention part 13 is fixed by heat fusion to the outer shell 11 of the container body 10, and the filling container 100 inserted into the cylinder 210 of the grease gun 200 is a pressure plate 220 When pressurized by, the pressure on the discharge side of the filling container 100 increases and expands, and the backflow prevention part 13 functions to pressurize and adhere to the inner wall surface of the cylinder 210 using the expansion pressure.

Accordingly, the backflow prevention part 13 prevents the discharged grease 60 from flowing backward (in a direction opposite to the discharge direction) between the filling container 100 and the cylinder 210.

Therefore, if the remaining grease 60 remains in the cylinder 210 of the grease gun 200 when refilling the charging container 100, the residual grease 60 gets on the body or falls on the floor, making the surrounding cleanliness poor. If stepped on, there may be a risk of safety due to slipping, and the residual grease 60 and the refilled grease 60 are mixed so that the quality of the grease 60 cannot be maintained, and the backflow prevention part 13 is a grease gun ( 200) can be solved by removing the residual grease.

Meanwhile, as shown in FIG. 5, the backflow prevention part 13 may be interposed between the outer skin 11 and the inner skin 12 of the container body 10 in another embodiment to be more rigidly fixed.

At this time, since the backflow prevention part 13 is wrapped in the outer shell 11, the frictional force with the cylinder 210 decreases and oil may leak. To prevent this, the cutout portion is provided in the outer shell 11 of the container body 10. (111) is partially formed so that the backflow prevention part may be exposed to the outside of the shell 11.

Figure 6 is a perspective view of a refill grease filling container according to a second embodiment of the present invention, Figure 7 is a cross-sectional view of Figure 6, Figure 8 is a state of use of the refill grease filling container according to the second embodiment of the present invention to be.

6 to 8, the second embodiment includes the first embodiment, but the container body 10 reinforces the tertiary sealing portion 40 not filled with the grease 60, and The container body 10 and the connection body 50 made of the same material as the container body 10 are double-coupled to the outside of the shell 11 so that the sealing part 40 is not identified.

First, the third sealing unit 40 functions to store the remaining grease 60 for a long period of time when the grease 60 of the filling container 100 is not used up.

This third sealing part 40 has the same shape as the first sealing part 20, and after separating the partially used filling container 100 when the grease gun 200 is not used for a long time, the third sealing part 40 ) By cutting the center of the third sealing portion 40 as a starting point, the filling container 100, which is not used, functions to be stored in a sealed state for a long time.

On the other hand, the unused filling container may be damaged by the load of the folded container body 10 because the container body 10 is folded by the tertiary sealing part 40, the same as the container body 10 to prevent this. The connection body 50 made of a material is configured to be double-coupled to the container body 10 so as to surround the tertiary sealing part 40 that is not filled with the grease 60.

This connection body 50 reinforces the tertiary sealing portion 40 and functions so that the tertiary sealing portion 40 is not identified.

In more detail, the connection body 50 prevents the tertiary sealing part 40 from being folded and can be identified as one container body 10, thereby making the appearance of the container body 10 beautiful. It also serves as an additional function.

Meanwhile, the connection body 50 may be heat-sealed, and may be configured by applying an adhesive (not shown) in addition to the attachment to the surface of the container body 10. At this time, since the bonded connection body 50 is detachable, the sealed state can be further reinforced by attaching it to the tertiary sealing part 40 cut after using the grease through the connection body 50.

Since the embodiments described in the present specification and the configurations shown in the drawings are only the most preferred embodiment of the present invention, and do not represent all the technical ideas of the present invention, various equivalents that can replace them at the time of the present application And it should be understood that there may be variations.
