DESCRIPTION

Tube capable of preventing air infiltration Background of the invention

The present invention described herein refers to a tube-shaped container that prevents the entry of air, and more specifically, to a tube-shaped container that prevents the entry of air that can prevent content deterioration by installation of a nozzle that rises and opens by pressing the contents of the inside of the outer part to allow the nozzle to open only when the content is discharged, maintaining a closed state of a nozzle exit hole unless the content is discharged even when the plug is open, and thus prevent air from entering a tube body through the outlet hole.

Generally, the tube packages include a tube body containing the contents, a tube neck coupled to the upper part of the tube body that supports the tube body and includes an outlet to discharge the contents in the body of tube, in addition to a removable cap that attaches to the neck of the tube to open and close the outlet hole. As examples, reference is made to documents KR 101004637 B1; EP 0046464 A1; US 4561570 A; US 5992764 A; KR 20100029921 A; GB 377138 A; GB 425943 A; FR 996343 A, whose descriptions, particularly referring to the same tube containers, are incorporated herein.

The tube containers are used by separating the cap from the tube body and then pressing the tube body to discharge the contents through the outlet hole. In a state where the plug opens, since the outlet orifice is always exposed to the outside, air can flow into the tube body. Consequently, the content may deteriorate.

Also, when the content is spread directly on the affected part when the tube body is pressed, the contaminants around the affected part can be mixed with the content that is discharged. In this case, when the tube body loses pressure after spreading the content, the content returns to the inside of the tube body due to the internal pressure of the tube body, allowing contaminants mixed with the content to adhere to the wall internal orifice or enter the tube body and, therefore, deteriorate the contents.

Summary of the invention

The present invention provides a tube-shaped container that prevents the entry of air, which can prevent the deterioration of the content by installing a nozzle that rises and opens by pressing the content inside an outer piece to allow the nozzle open only when the content is discharged, maintaining a closed state of a nozzle exit hole unless the content is discharged even when the cap is open, and thus prevent air from flowing into the tube body through the exit hole.

The present invention also provides a tube-shaped container that prevents the entry of air that can prevent the deterioration of the contents, preventing the content remaining in an exit orifice from being discharged to the outside and then returned to the interior again through operations of raising and lowering an external nozzle and thus preventing the content contaminated by direct spreading of the content on an affected part from adhering to the interior of the nozzle or flowing into the tube body.

The embodiments of the present invention provide tube-shaped containers that prevent the entry of air, and include: a tube body that contains contents and includes an outlet piece formed on an upper part thereof to discharge the content; an internal nozzle that includes a coupling piece inserted in the outlet piece and that has a hole for content entry in communication with the outlet piece, and a locking rod that protrudes upwardly from a central part of the piece of coupling; an external nozzle seated at the upper end of the coupling piece which in turn covers the blocking rod, rising and falling by the pressure of the content, and is opened and closed by the blocking rod; a holding body coupled to an inner side of the outlet piece which in turn covers a part of the outer nozzle and includes a hollow piece to allow the outer nozzle to rise and fall; an elastic body disposed within the clamping body that in turn surrounds the outer nozzle to allow the outer nozzle to lower; and a closure plug coupled to an outer side of the outlet piece which in turn covers the internal nozzle and the external nozzle.

The fastener body includes a settlement plug that surrounds an outer circumferential surface of the fastener body and sits at an upper end of the outlet piece and a fastener protrusion formed below the settlement plug so that it is fixed to the inner side of The output piece.

In some embodiments, the outer nozzle may include: a settlement piece having a piston structure in which an upper end part and a lower end part of the outer circumferential surface thereof are in contact with the wall surface internal holding body; and a content movement tube that extends upwardly from the settlement piece to form a conduit through which the

With reference to Figures 1 to 4, a tube-shaped container that prevents the entry of air according to an exemplary embodiment of the present invention may include a tube body 100, an internal nozzle 200, an external nozzle 300, a clamping body 400, an elastic body 500 and a closure cap 600.

The tube body 100 may contain contents and includes an outlet piece 110 coupled to an upper part of the tube body 100 so as to discharge the content. The outlet piece 110 may include a first screw thread 111 on the outer circumferential surface of the outlet piece 110 so that it threadedly engages the closure cap 600 described below.

The internal nozzle 200 may be placed in the outlet 110 to guide the movement of the contents through the outlet 110 and open and close the external nozzle 300 described below. The internal nozzle 200 includes a

coupling piece 210 and a locking rod 220.

The coupling piece 210 is placed in the output piece 110 to guide the movement of the content through the output piece 110. The coupling piece 210 has a content entry hole 211 formed on top of it for communicating with the output part 110 and thus allowing the content downloaded through the output part 110 to enter. In the content entry hole 211, a plurality of extension pieces 212 can be arranged at a constant interval to extend from the internal circumferential surface of the coupling piece 210 to the central part thereof.

The coupling part 210 may include a coupling protrusion 213 formed in the outer circumferential surface thereof to engage a coupling slot 450 of the clamping body 400, described below.

In addition, the coupling piece 210 may include a locking protrusion 214 formed at a lower end thereof to be in contact with a lower end of the inner side of the output piece 110, so as to prevent the content from moving Through the outlet part 110, it is filtered outside the internal nozzle 220.

The locking rod 220 can protrude upwardly from the central portion of the coupling piece 210 in which the plurality of the extension pieces 212 is attached, and can open and close an outlet opening 321 of the external nozzle 300 according to the raising or lowering of the external nozzle 300.

The blocking rod 220 may include a protrusion piece 221 formed in the end portion thereof and protruding outside the external nozzle 300 so as to prevent the contents from sticking in a space that defines the outlet opening 321 of the external nozzle 300.

Since the protuberance piece 221 is formed in the blocking rod 220, it is easy to distinguish the opening / closing of the nozzle according to the movement of the nozzle from the outside.

The external nozzle 300 is seated at the upper end of the coupling piece 210 while covering the blocking rod 220, and can be raised or lowered by the pressure of the contents while opening / closing by means of the blocking rod 220. The external nozzle 300 may include a settlement piece 310 and a motion tube containing 320.

The settlement piece 310 can be seated at the upper end of the coupling part 210 of the internal nozzle 200 to support the elastic body 500 described below. The settlement piece 310 can support the lower end of the elastic body 500 surrounding the content movement tube 320 to pressurize the elastic body 500 and thus contract the elastic body 500 when the external nozzle 300 rises according to the discharge of the content. On the other hand, when the discharge of the content is finished, the external nozzle 300 may fall due to the elastic force of the elastic body 500.

According to an embodiment of the present invention, the settlement piece 310 may have a cylindrical shape and may be configured to have a piston structure in which the upper and lower end of the outer circumferential surface of the settlement piece 310 are in contact with the internal wall surface of the clamping body 400. Thus, when the external nozzle 300 rises or falls, the balancing of the external nozzle 300 can be avoided, allowing the content to discharge uniformly and preventing the content from leaking along the inner wall of the clamping body 400.

The content movement tube 320 can extend upwardly from the settlement piece 310, forming a conduit through which the content introduced by the content entry hole 211 of the internal nozzle 200 can be displaced. The content movement tube 320 may have the outlet opening 321 formed at the end thereof and is opened / closed by the blocking rod 220, so as to allow the introduced content to be discharged to the outside.

The holding body 400 can be formed to have a cylindrical shape that covers a portion of the external nozzle 300 and engages the inner side of the outlet 110. The holding body 400 can have a hollow piece 410 in which the nozzle external 300 that moves along the discharge of the content can rise or fall, and can cover the outer circumferential surface so that it sits on the upper end of the outlet piece 110. The clamping body 400 includes a stopper of settlement 420.

In this embodiment, the clamping body 400 includes a clamping protrusion 430 formed below the settlement plug 420 and fixed to a clamping slot 120 of the outlet 110. Since the nozzle is easily installed in the tube container by the coupling of the clamping protrusion 430 with the clamping groove 112 of the outlet 110 after the integral modularization of the internal nozzle 200, the external nozzle 300, the clamping body 400 and the elastic body 500, it is possible to avoid that air flows into the tube body 100 when the closure cap 600 is opened.

Meanwhile, the holding body 400 may include a support plug of the elastic body 440 inclined inwardly at the upper end thereof, around the inner circumferential surface thereof, and thus support the elastic body 500 described below. The elastic body support cap 440 can support the upper end of the elastic body 500 to contract the elastic body 500 when the outer nozzle 300 rises.

In addition, the clamping body 400 may have a coupling groove 450 formed on an inner side of the clamping body 400 and corresponding to the coupling boss 210, so that it engages the internal nozzle 200.

The elastic body 500 surrounds the external nozzle 300 within the holding body 400 and can descend through the external nozzle 300. The elastic body may have one side seated in the settlement piece 310 and may have the other side in contact with the plug elastic body support 440 of the clamping body 400.

The elastic body 500 can contract according to the movement of the external nozzle 300 due to the pressure of the content when the tube body 100 is pressurized, and it can expand when the tube body 100 is depressurized, providing an elastic force to the settlement piece 310 of the external nozzle 300 and thus allow the external nozzle 300 to be lowered.

The closure cap 600 covers the internal nozzle 200 and the external nozzle 300, and can be threadedly coupled to the outside of the outlet piece 111. The closure cap 600 may include a second screw thread 640 formed on the internal circumferential surface of the same and coupled to the first screw thread 111 so that it is threadedly coupled to the outlet piece 110.

In this embodiment, the closure cap 600 may include a pressurization protrusion 610 formed on an upper part of the interior thereof and pressurizing the external nozzle 300. The pressurization protuberance 610 can pressurize the upper end of the external nozzle 300 to limit the rise of the external nozzle 300, thereby preventing the contents from discharging even when the tube body 100 is pressurized while the closure cap 600 is closed. Thus, it is possible to prevent the contents from being consumed unnecessarily and that the inside of the closure cap 600 is contaminated by the loss of content.

The closure cap 600 may include a coupling restriction protrusion 620 that is provided within the closure cap 600 and sits on the settlement cap 420 of the clamping body 400 to limit the thread engagement when the closure cap 600 is threadedly engages the outlet 110. When the closure plug 600 is forcefully coupled to the outlet 110, the external nozzle 300 may be excessively inserted and trapped in the internal nozzle 200 by the pressurization of the pressurization protrusion 610 Accordingly, the malfunction of the nozzle can be avoided by allowing the coupling restriction protuberance 620 provided within the closure plug 600 to be in contact with the settlement plug 420 and thus prevent thread engagement of the closure plug 600.

On the other hand, the closure cap 600 may include a non-slip protrusion 630 on the outer circumferential surface thereof to facilitate thread engagement and separation with / from the outlet piece 110.

Hereinafter, an operation procedure of the tube-shaped container that prevents the entry of air according to an exemplary embodiment of the present invention will be described with reference to Figure 4.

Figure 4 is a view illustrating an operational state of a tube-shaped container that prevents the entry of air according to an exemplary embodiment of the present invention. With reference to Figure 4, in the tube-shaped container that prevents the entry of air according to the exemplary embodiment of the present invention, when the outlet opening 321 of the external nozzle 300 is closed by the blocking rod 220 of the internal nozzle 200 and the tube body 100 is pressurized, the contents can move upwards through the outlet part 110 and then can flow to the content movement tube 320 of the external nozzle 300 through the orifice Content entry 211.

As described above, while the content flows to the content movement tube 320, the content can apply a pressure to the external nozzle 300, allowing the external nozzle 300 to rise. When the external nozzle 300 rises, the outlet opening 321 , which is being closed by the blocking rod 220 of the internal nozzle 200, can be opened, allowing the contents to be discharged to the outside through the outlet opening 321.

On the other hand, when the tube body 100 is depressurized, the content may stop moving. In this case, the elastic body 500 that contracts according to the rise of the external nozzle 300 can be stretched, providing an elastic force to the external nozzle 300 and thus allowing the external nozzle 300 to lower. When the external nozzle 300 falls, the hole Output 321 can be closed by means of the blocking rod 220 of the internal nozzle 200, thus preventing the contents from being discharged.

As described above, a tube-shaped container that prevents the entry of air according to an embodiment of the present invention, can prevent the deterioration of the content, by installing a nozzle that rises and

It is opened by pressing the contents into an external part to allow the nozzle to open only when the content is discharged, maintaining a closed state of an outlet opening of the nozzle unless the content is discharged even when the plug is open, and thus prevent air from entering a tube body through the outlet orifice.

In addition, a tube-shaped container that prevents the entry of air can prevent the deterioration of the contents, preventing the content remaining in the exit orifice from being discharged to the outside and then returning to the interior again through up and down operations. lowering of an external nozzle and thus preventing the content contaminated by the direct spreading of the content on the affected part from adhering to the inside of the nozzle or flowing into the body of the tube.

The subject matter described above should be considered illustrative and not restrictive, and the appended claims are intended to cover all such modifications, improvements and other embodiments that are within the scope of the present invention. Therefore, according to the maximum scope permitted by law, the scope of the present invention should be determined by the broadest permissible interpretation of the following claims and will not be restricted or limited by the above detailed description.
