Description

Compressed jet container

The present invention relates to a compression injection container, and more particularly, to maintain the contracted state until the soft corrugated pipe is assembled to the container, it is invented to facilitate the assembly.

In addition, the present invention is invented so that the inner container is released by the impact or vibration in the manufacturing process and use process, the contents are leaked or mixed with compressed air to prevent deterioration or deterioration of quality.

Recently, as global warming is accelerated due to environmental pollution and increased carbon dioxide emissions, side effects are greatly increasing, and various measures and regulations have been prepared to prevent such problems, but they are not effective.

As one of such measures, efforts to reduce the amount of harmful gases such as Freon gas, carbon dioxide, methane gas, dimethyl ether (DME) and sulfuric acid aerosol that are injected into the container or can of spray products and released into the atmosphere when using the product Is being tried.

Recently, a corrugated pipe having a plurality of corrugations formed in the longitudinal direction on the outer circumferential surface of a PET container is inserted into the compression injection container to fill the contents inside the corrugated pipe, and compressed air is injected between the corrugated pipe and the compression injection container, thereby providing compressed air. By spraying the contents of the inside of the corrugated pipe by means of, there has been known a technology that makes it possible to simply use the spray product without using any air pollutant Freon or methane gas.

As such a known technology, according to Korean Patent Registration No. 10-1137769, a forming block is mounted between a first mold and a second mold, and radially in a state in which it is mounted on the first mold according to the operation of the second mold. A wrinkle forming structure has been proposed in which a plurality of forming blocks arranged are moved forward and backward by a second mold and wrinkles are formed.

In order to couple the corrugated pipe 10 to the container 20, first, the valve device 40 provided in the metal cap 30 and the inlet of the corrugated pipe 10 are bound.

Then, after the corrugated pipe 10 enters the inside of the container 20, the circumference of the metal cap 30 is pressed along the perimeter of the inlet side of the container 20.

The valve device 40 which connects the metal cap 30 and the corrugated pipe 10 has a spray button after the contents of the inside of the compressed spray container 20 are moved through the nozzle by pressing the spray button 50. 50) is injected into the outlet.

On the other hand, conventional inner containers are soft PE material suitable, but PE has a problem in that the locking jaw falls off when combined with the metal cap due to the characteristics of the soft material is limited in the field of use.

In general, the portable spray container is standardized in the size of the injection port (inner diameter 25.4mm = 1 inch), as well as the size of the metal cap coupled thereto, as well as the diameter of the locking step coupled to the metal cap.

Therefore, the diameter of the upper end of the corrugated pipe assembled through the inlet is small in size, so that the size of the lower end of the corrugated pipe filled with the contents (capacity portion filled with the contents) cannot be enlarged. This is difficult.

Meanwhile, the conventional corrugated pipe 10 mainly uses a synthetic resin material such as PET or PE.

The material such as PET or PE has excellent moldability and elasticity, but has a disadvantage in that its volume becomes large for a time from forming the corrugated pipe 10 to assembling into the compression injection vessel 20.

That is, the volume of the corrugated pipe 10 is increased by elasticity of the material itself, or when the outside air flows through the inlet, and expands. The diameter of the upper and lower boundary portions of the corrugated pipe 10 is mainly formed as shown in FIG. It is deformed to become large.

Typically, the portable spray container has a standard diameter of the inlet.

As such, when the volume of the corrugated pipe 10 is partially expanded, in particular, the upper part of the corrugated pipe 10 becomes larger than the inner diameter of the inlet of the compression injection container 20, thereby causing a defect that cannot be assembled. (FIG. 3)

On the other hand, according to the Republic of Korea Patent Publication No. 10-2014-0117338, the medium between the metal cap and the inner container in order to improve the binding capacity with the metal cap while selecting the content filling container with a soft material of good chemical resistance A structure that binds to each other has been proposed.

Here, as a method for binding the socket and the inner container, a male screw portion is mainly formed outside the inlet portion of the inner container, and a female screw portion is formed in the socket to screw the male screw portion.

However, when shock and vibration are continuously generated during manufacturing, distribution, or use, some of the screws connecting the socket and the inner container are often loosened.

When the screws are loosened, the contents contained in the inner container may flow out into the space containing the compressed air, or the compressed air may be introduced into the interior to deteriorate or deteriorate the contents.

SUMMARY OF THE INVENTION An object of the present invention is to provide a compression injection container which can be easily assembled by preventing the volume from expanding due to its own properties or external factors after forming the corrugated pipe.

Another object of the present invention is to provide a compression injection container which can economically benefit by preventing product defects and improving productivity.

Still another object of the present invention is to provide a compression injection container which can prevent the loosening of a screw part in a state in which a socket and an inner container are assembled.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the accompanying drawings are only intended to describe the technical spirit of the present invention in more detail, the technical spirit of the present invention is not limited thereto, and various modifications are possible in advance. In addition, in the specification of the present invention, the same reference numerals will be used for the same parts, and a detailed description of parts that can be easily created by those skilled in the art as known in the art will be omitted. Let's do it. In addition, the same code | symbol is used about the same part.

First, the corrugated pipe 10 may be formed by a conventional manufacturing method. For example, after the hot heat is supplied to the inside of the manufacturing process using a synthetic resin material capable of forming a corrugated pipe, and the heat deformation is maintained, the cylinder (not shown) is fixedly attached to the tip of the piston rod. The forming blades advance to form a pleat along the pleats.

By this process, the corrugated pipe 10 forms a hollow tube shape, and a threaded portion is formed around the socket 30 in a state where the inlet portion is opened, and the body has a plurality of press-fit portions along the vertical direction ( V) is repeatedly molded.

The socket 30 has a locking jaw formed on the outside of the upper end and is coupled with the metal cap 50. The valve device 40 is provided inside the metal cap 50, and the valve device is pressed by pressing the nozzle 41. 40 is assembled to open and close.

Therefore, after assembling the corrugated pipe 10 and the socket 20 bound to the bottom surface of the metal cap 50 in the assembling process, the circumference of the metal cap 50 is forcibly pressed into the inlet of the container 20 to each other. To make a binding.

The button member 60 is fitted to the nozzle 41.

In this way, the corrugated pipe 10 of which the corrugation is completed and the container 20 are bound to the container 20 by using the metal cap 50 to which the nozzle 41 is coupled, for example, in a state of filling 2 atmospheres of air. .

Then, when the contents are filled into the corrugated pipe 10 through the nozzle 41, the air pressure increases between the corrugated pipe 10 and the container 20 due to the volume decrease as the corrugations are unfolded. )

By operating the nozzle 41 exposed to the outside of the container 20 due to this pressure increase, the contents of the inside of the container may be ejected as in the prior art.

The most important feature of the present invention is to block the expansion of the corrugated pipe 10 in the compressed state just before assembly with the container 20 so that the assembly can be made smoothly.

That is, the corrugated pipe 10 is characterized in that it is assembled so that the protective film 70 is further covered so as not to expand the indentation (V) formed along the circumferential surface.

The protective film 70 is inserted into the outer side of the corrugated tube 10 in the form of a tube to prevent the corrugated tube 10 from expanding its volume due to its own elasticity or air being injected into it.

The heat shrink film has the property of being tightened while shrinking in the width direction and the longitudinal direction at the shrinkage rate set at the time of manufacture when the heat shrink film is assembled to the outside of the corrugated pipe 10.

Therefore, since the corrugated pipe 10 itself blocks the phenomenon that the diameter expands while the outside air is injected into the elasticity or the inside thereof, it is prevented that a defect occurs due to the inlet in the process of assembling the container 20. It can be.

On the other hand, the protective film 70 is filled between the corrugated pipe 10 and the inner diameter of the container 20 in the state of being damaged as shown in FIG. 7 when the contents are filled through the nozzle 41 into the corrugated pipe 10. Located in space.

At this time, when the corrugated pipe 10 is expanded by filling the contents of the protective film 70, it is also preferable to form a cut line 71 in the longitudinal direction at one or two locations.

In addition, the protective film 70 is that the corrugated pipe 10 is mainly deformed and expanded in the center, so that it may be installed only in the central position.

Meanwhile, the embodiment of FIGS. 9 to 18 will be described.

First, the inner container 130 includes a corrugated pipe structure and a pouch structure in which the tube container is wound in the circumferential direction, and the corrugated pipe is supplied with hot heat into a container made of synthetic resin in a manufacturing process to enable thermal deformation. After holding, it is common for the forming blades fixedly attached to the tip of the piston rod to move forward to form a corrugation around the corrugated pipe by the operation of a cylinder (not shown).

By this process, the inlet part is opened in the shape of a hollow tube, and many wrinkles are repeatedly formed along the circumferential surface.

The inner container 130 of the corrugated pipe structure is connected by screwing the socket 140 having excellent deformation strength.

The socket 140 has a locking step 142 to be caught by the metal cap 120 to the outside of the upper end.

The locking jaw 142 is prevented from being caught by the pressing protrusion 121 protruding toward the inner diameter of the metal cap 120 by the size and structure of the standard.

In the center of the metal cap 120, the nozzle 151 is assembled with the valve device 150 in a state where it is exposed upward.

Therefore, by assembling the socket 140 bound to the inner container 130 to the bottom surface of the metal cap 120 in the assembling process, the upper end of the socket 140 is fitted into the inner diameter of the metal cap 120, and then presses the protrusions 121. ) Is to be caught by the locking step 142.

Here, the male screw portion 131 is formed outside the inlet portion of the inner container 130, and the female screw portion 141 screwed to the male screw portion 131 is formed in the socket 140 and screwed thereto.

Therefore, the inner container 130 and the socket 140 are separated and manufactured to have different deformation strengths, different materials, large corrugated pipes, and the like, and are connected to each other by screwing in the assembling process.

At this time, the outer diameter portion of the mounted portion where the metal cap 120 is coupled to the socket 140 is formed into a hexagonal or octagonal shape to prevent slippage in the process of screwing the inner container 130 using an assembly tool (T). While it is good to be able to improve the assemblability (Fig. 18).

On the other hand, between the socket 140 and the inner diameter of the inlet side of the inner container 130 is provided between the packing 180 having compression elasticity is assembled between the socket 120 and the inlet of the inner container 130 is generated. It is desirable to seal any gaps that may be present.

In addition, a packing 181 is inserted between the inner surface of the metal cap 120 and the contact surface of the socket 140 to maintain airtightness.

The spray can 110 is formed of a metal material such as aluminum or a synthetic resin having excellent strength while the inlet is opened in a hollow container shape, and the valve device 150 accommodated in the socket 140 is provided by a user with a spray button. The pressing operation of 152 is controlled to spray the contents filled in the inner container 130 through the nozzle 151.

In this case, when the inner container 130 is selected as a corrugated pipe structure, it is preferable to select the material as PE, PET, PP as an example, and the socket 120 is made of another material such as PP, PET, ABS, and PC. Can be selected.

Such a compressed injection container is mounted between the inner container 130 and the spray can 110 by using the metal cap 120 coupled with the nozzle 151 in a state of filling 2 atmospheres of air, for example, into the spray can 110. It will be assembled in the state.

Then, when the contents are filled into the interior of the inner container 130 through the nozzle 151, the air pressure increases between the inner container 130 and the spray can 110 due to the volume decrease while the wrinkles are expanded. 8 atm)

When the nozzle 151 exposed to the outside of the spray can 110 is manipulated due to such an increase in pressure, the contents of the container may be ejected.

Here, since the inner container 130 and the socket 140 are screwed, the screw part is released by repeated shocks or vibrations during the manufacturing process, distribution, or use process, so that the sealed state of the inner container 130 may be lost. .

Therefore, the locking groove 160 is excavated at a predetermined interval along the side wall in the inner diameter portion of the socket 140, and the control protrusion 170 is caught in the locking groove 160 in the inner container 130 to prevent loosening. ) Can prevent the inner container 130 from being loosened by protruding molding. (FIGS. 9 to 15)

On the other hand, according to another embodiment of the present invention, the locking grooves 160 are dug repeatedly at regular intervals in the vertical direction along the circumferential surface at the lower end of the socket 140, and the upper portion of the flange 133 in the inner container 130. The control projections 170 may be protruded to be caught by the locking grooves 160 to prevent loosening.

By the elastic grooves 145, the control protrusion 170 is to maintain the elasticity when passing over the protrusion of the locking groove 160.

The locking groove 160 and the control protrusion 170 are formed to be inclined in the direction in which the contact surface is rotated in the screw tightening direction to the socket 140, as shown in Figs. In the direction, it may be molded at a right angle.

In addition, as shown in FIG. 18, the locking groove 160 and the control protrusion 170 may be formed in a triangular shape or a semicircular shape.

Since the locking grooves 160 and the control protrusions 170 both retain their elasticity with synthetic resin materials, when the external force is applied in the screw tightening direction by forcibly applying force in the assembling process, the control protrusions 170 are locked. Riding over (160) is possible.

However, when all parts of the compression injection container are subjected to vibration or shock in a state where assembly is completed, loosening of the socket 140 and the inner container 130 may be prevented in advance.

In the above, the present invention has been described based on specific embodiments, but in addition to the present invention, there may be various modifications within the technical idea of the present invention, and the technical scope of the present invention is not limited only to the above embodiments.

The present invention is applied to the crimp tube technology of a compression injection vessel. In particular, it is characterized in that the volume is expanded during the assembly process to prevent the occurrence of defects that can be applied to the field of metal materials, plastic spray containers that can fill the contents of a variety of properties.
