Description
- This application claims priority to and the benefit of Korean Patent Application No. 10-2010-0006190 filed in the Korean Intellectual Property Office on Jan. 22, 2010, the entire contents of which are incorporated herein by reference.
- (a) Field of the Invention
- The present invention relates to a dual compartment pouch having two chambers for separately receiving two types of liquid components. More particularly, it relates to a dual compartment pouch separately storing two types of liquid components that are mixed prior to use and having a pressure-openable non-sealing line, and a heat sealing mould for manufacturing the same.
- (b) Description of the Related Art
- A pouch having an externally isolated chamber formed by heat-compressing two films has excellent water resistance and air-tightness, and can be easily processed into a certain shape so that it can be used as a package for detergent, skin lotion, a medical material, or a beverage.
- Unlike a typical pouch containing a single component liquid, the duplex storage pouch disclosed in the U.S. Patent Laid-Open Publication No. 2004/0079763 separately stores different types of liquid or stores a liquid and a powder in one pouch, and pressure is applied to a portion that separates the two different materials in order to mix them prior to use.
- The disclosed duplex storage pouch has a chamber divided by a chevron-shaped seal. When external pressure is applied to one of the divided chambers, the pressure is concentrated to the apex of the chevron shape the chambers, and because the apex portion is fragile, the chevron seal that divides the two chambers is opened. Good examples include a package including a viscous liquid (e.g., hair dye or oxygenated water) that should be kept separate from the other material prior to use.
- The duplex storage pouch is illustrated to be opened at the boundary between the two chambers when a user presses the pouch with their hand, but it needs much stronger power to open the apex area. In other words, when the user presses the chamber, the pressure is uniformly distributed to the entire inner area of the chamber rather than being concentrated at one point so that partial pressure applied to the apex of the saw-shaped sealing line is not sufficient even though a user presses strongly so that the pouch cannot be easily opened.
- The inventor of the present invention disclosed a duplex pouch in Korean Utility No. 20-2009-000590. The duplex pouch has a structure in which at least one of triangular spaces having an apex is included in a sealing line that functions as a boundary between the two chambers so that a specific portion of the sealing line has weak adhesive strength compared to another portion.
- The duplex pouch suggested by the inventor of the present invention has a structure in which a sealing area is significantly narrowed at a specific area so that a portion at which the adhesive is weaker than the other portion is formed. However, the weak portion cannot be easily opened unless strong power is applied.
- The above information disclosed in this Background section is only for enhancement of understanding of the background of the invention and therefore it may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the art.
- The present invention has been made in an effort to provide a duplex compartment pouch that can store different types of components in a chamber divided into two and has a sealing line that becomes the boundary of the chamber and a pressure-openable non-sealing line. Here, a specific portion of the sealing line is not opened by a static load applied while being transported or being stacked, and the pressure-openable non-sealing line is opened by a dynamic load that is applied by user's pressure.
- In addition, the present invention provides a heat-sealing mould for manufacturing a duplex pouch having a pressure-openable non-sealing line to form a portion of a sealing line that functions as a boundary of the separated chambers with the aforementioned non-sealing line.
- The duplex pouch according to the present invention includes a first chamber and a second chamber that are sealed by an external sealing line at their edges and a middle portion of the two chambers is heat-sealed by an inside sealing line to contain different types of liquid contents, respectively, a pressure-openable portion formed at a middle portion of the inside sealing line, a non-sealing unit formed in a round triangle or semicircle shape at the center of the pressure-openable portion by first and second branch sealing lines divided by the inside sealing line and then extended, a long non-sealing line provided in a middle of the first branch sealing line and communicating the first chamber and the non-sealing unit, and a short non-sealing line provided in a middle of the second branch sealing line and communicating the non-sealing unit and the second chamber.
- The pressure-openable may further include a pair of enhanced sealing lines forming an acute angle by being extended from the inside sealing line, and the first and second branch sealing lines are respectively divided into two from the enhanced sealing line and then extended.
- It is preferable that the width of each of the first and second branch sealing lines is set to correspond to ⅓ of the width of the inside sealing line.
- In addition, it is preferable that the length of the long non-sealing line is 4 to 10 mm, and that the length of the short non-sealing line is 0.4 to 0.9 times of that of the non-sealing portion.
- A heat-sealing mould for manufacturing a duplex pouch having a pressure-openable non-sealing line includes a heat compression pad at one part thereof and a linear heater at another part to form two separate chambers by heat-sealing external and internal sealing lines to two sheets of films. The heat compression pad includes an inner sealing pad corresponding to an inner sealing line, an enhanced pad forming an enhanced sealing line, and first and second branch sealing pads respectively corresponding to first and second branch sealing lines, and a long notch and a short notch are provided for forming the long non-sealing line and the short non-sealing line in the first and second branch sealing pads.
- In addition, instead of the long and short notch in the heat-compression pad, a long heat sink and a short heat sink may be respectively provided to form a long non-sealing line and a short non-sealing line in the linear heater.
- The duplex pouch according to the present invention may separately store liquid components that should be separate prior to use, such as hair dye or oxygenated water, in the first and second chamber, respectively.
- The pressure-openable portion disposed between the first and second chambers has a structure in which the non-sealing portion disposed between the first and second chambers is double-blocked with the long non-sealing line and the short non-sealing line so that the liquid components respectively stored in the first and second chambers cannot be mixed by a static load.
- Since the long non-sealing line and the short non-sealing are substantially not sealed, they may be opened by a dynamic load generated when a user presses the first chamber with a sufficient amount of power so that the two different components respectively stored in the first and second chambers can be mixed.

- As shown in
FIG. 1 , a duplex pouch according to the present invention is formed of afirst chamber 6 and asecond chamber 8. The first andsecond chambers outside sealing line 2 that is formed by heat-sealing the outside perimeter thereof and are simultaneously separately divided by an insidesealing line 4 that substantially crosses the center between the first andsecond chambers - The first and
second chambers - In addition, a pressure-
openable portion 10 is provided at the longitudinal center of the insidesealing line 4 that forms the boundary the twochambers - As shown in
FIG. 2 , the pressure-openable portion 10 includes a rounded triangular or semi-circularnon-sealing portion 16 formed by a firstbranch sealing line 12 and a secondbranch sealing line 14 that are divided into two and extended from the inside sealing line, and a longnon-sealing line 18 and a shortnon-sealing line 20 are respectively provided in the middle of each of the first and secondbranch sealing lines - Here, it is preferred that the width of each of the first and second
branch sealing lines inside sealing line 4. - As in a typical pouch, in the duplex pouch according to the present invention, the
outside sealing line 2 and theinside sealing line 4 are sealed with a width of 6 mm or 7 mm, and accordingly, the width of each of the first and secondbranch sealing lines - As shown in
FIG. 3 , the firstbranch sealing lines 12 that are adjacent to each other at lateral sides are integrally sealed, and thenon-sealing line 18 has a structure in which two films are simply overlapped. - That is, the surface of the
non-sealing line 18 is melted due to a peripheral temperature that is maintained at a range of 200° C. to 275° C. during the heat-sealing process, the portion of thenon-sealing line 18 is not pressed by a heater so that the inside thereof is overlapped rather than being internally sealed, and after thenon-sealing line 18 is heat-sealed and then cooled, it is difficult to distinguish the integrally sealed firstbranch sealing line 12. However, thenon-sealing line 18 is not internally sealed but the two parts thereof internally contact each other so that thenon-sealing line 18 is opened when a dynamic load is applied thereto, and thenon-sealing line 20 of the secondbranch sealing line 14 has the same structure as of thenon-sealing line 18 but is shorter than thenon-sealing line 18. - With the above-described structure, the long
non-sealing line 18 and the shortnon-sealing line 20 are always opened respectively in the first and secondbranch sealing lines second chambers - In further detail, the long
non-sealing line 18 and the shortnon-sealing line 20 are sealed in an air-tight manner due to an electrostatic force according to the characteristic of the material at the early forming stage so that they are maintained in the closed state unless a user externally presses the pouch. - In the duplex pouch of the present invention, the external force applied to the first and
second chambers - Since the static load is externally applied to both the first and
second chambers second chambers non-sealing line 18 and the shortnon-sealing line 20 in the closed state, and accordingly the pouch is not opened. - However, the long
non-sealing line 18 has a relatively long length and thus the static load may cause leakage therein so that the liquid component of thefirst chamber 6 may flow into thenon-sealing portion 16. However, the flow of the liquid component is blocked by the shortnon-sealing line 20 in thenon-sealing portion 16, and thenon-sealing portion 16 is expanded in a water blister shape as the leaked liquid component fills thenon-sealing portion 16 so that tension therebetween is increased. For this reason, the first andsecond chambers - Thus, the first and
second chambers - When the long
non-sealing line 18 of the firstbranch sealing line 12 that communicates between thefirst chamber 6 and thenon sealing portion 16 is set too long, the close contact state cannot be maintained so that the length of thenon-sealing line 18 may be limited to an appropriate length, and the open length of thefirst chamber 6 caused by pressure with a user's palm is preferably set to 4 to 10 mm according to experiments of the inventor. - When the length is set to be longer than 11 mm, liquid components of the
first chamber 6 of the lowest one of the pouch stack may leak to thenon-sealing portion 16 by static load due to the weight of the upper pouches. On the contrary, when the length is set to be shorter than 10 mm, the user needs to increase the pressure force to open the pouch. - In addition, the length of the short
non-sealing line 20 is set to be relatively short to block flow of the liquid component and is opened only when the dynamic load is applied thereto, and is optimized to be in a range of 0.4 to 0.9 times the length of the longnon-sealing line 18 formed in the firstbranch sealing line 12. - When the length of the short
non-sealing line 20 is shorter than 0.4 times the length of the longnon-sealing line 18, the user needs to increase pressure force to open the pouch, and when the length of the shortnon-sealing line 20 is longer than 1.0 times the length of the longnon-sealing line 18, a liquid component may leak when the static load is applied together with external impact. - In the duplex pouch of the present invention, the long
non-sealing line 18 is set to 6 mm and the shortnon-sealing line 20 is set to 3.5 mm for optimizing desired operation. - In the duplex pouch with the above-described configuration, components of the duplex pouch are set to be mixed when the user externally presses the
first chamber 6 with a finger or palm. - When the user presses the
first chamber 6, the liquid components in thefirst chamber 6 brings about pressure and the pressure is applied to the longnon-sealing line 18 of the pressure-openable portion 10 as the static load such that it is opened. - In other words, the long
non-sealing line 18 passes the liquid component to thenon-sealing line 16 when the user presses thefirst chamber 6, and the liquid component that has leaked into thenon-sealing portion 16 is pushed into thesecond chamber 8 while opening the shortnon-sealing line 20 and thus the two liquid components are mixed through repeatedly pressing thefirst chamber 6. - In the duplex pouch of the present invention, the pouch is opened by the dynamic load generated from the user's external force so that the first and
second chambers - That is, since the applied static load is evenly distributed in the entire areas of the first and
second chambers non-sealing line 18 so that the liquid component of thefirst chamber 6 is not mixed with the component in thesecond chamber 8. - A strong static load may be instantly applied to the pouch due to external impact during transportation of the pouch. In this case, only the long
non-sealing line 18 is opened and thenon-sealing portion 16 and thesecond chamber 8 are double-blocked by the shortnon-sealing line 20. That is, the instant variation due to static load may open the longnon-sealing line 18 but cannot open the shortnon-sealing line 20. - Accordingly, the liquid components in the first and
second chambers - The duplex pouch of the present invention is not limited thereto, and may be realized with a configuration shown in
FIG. 4 . - In this exemplary embodiment, a pressure-
openable portion 10 further includes a pair ofenhanced sealing lines 22 extended from aninside sealing line 4 with a constant width and rising upward, forming an acute angle. - At the vertex of the
enhanced sealing lines 22, a firstbranch sealing line 12 and a secondbranch sealing line 14 are extended to form a rounded triangular or semicircularnon-sealing portion 16 as in the previous exemplary embodiment, and a longnon-sealing line 18 and a shortnon-sealing line 20 are respectively formed in the longitudinal middle of the first and secondbranch sealing lines - With such a configuration, a portion where the
enhanced sealing line 22 is stronger than its periphery area so that the lateral sides of the firstbranch sealing line 12 receive a pre-stress force at theenhanced sealing line 22 is formed, and a space between theenhanced sealing lines 22 become concave in thefirst chamber 6 such that the concave portion maintains a vacuum condition without being filled with the liquid component. Accordingly, the longnon-sealing line 18 that is pre-stressed at theenhanced sealing line 22 has stronger adhesiveness compared to the structure of the aforementioned exemplary embodiment so that it cannot be easily opened even if a heavy static load is applied thereto. - Therefore, the duplex pouch of the present exemplary embodiment more efficiently separates liquid contents than the duplex pouch of the previous exemplary embodiment.
- In addition, the pair of
enhanced sealing lines 22 function as a path for guiding the liquid contents generating pressure to the longnon-sealing line 18 when the user presses thefirst chamber 6 so that thefirst chamber 6 and thesecond chamber 8 can be easily opened even though theenhanced sealing lines 22 have strong adhesive force. - That is, the user presses the duplex pouch of the exemplary embodiment with his thumb or palm such that the pressure can be concentrated to the inside of the
enhanced sealing line 22 of the pressure-openable portion 10, and accordingly the dynamic load generated by the liquid contents can be effectively applied to the longnon-sealing line 18. - The duplex pouch of the present invention can be realized through a heat-sealing mould shown in
FIG. 6 . - The duplex pouch of the exemplary embodiment related to
FIG. 4 andFIG. 5 can be manufactured through a heat-sealing mould, andFIG. 6 shows an enlarged view of one part of themould 10 a corresponding to the pressure-openable portion 10 and another part of themould 10 b opposite thereto. - The one part of the
mould 10 a has a pad for heat compression and the other part of themould 10 b has a linear heater for heat sealing, and the pad and the linear heater have the same shape. The pad of the one part of themould 10 a includes aninternal pad 40 a corresponding to theinside sealing line 4, anenhanced line pad 220 a forming theenhanced sealing line 22, and first andsecond branch pads branch sealing lines first branch pad 120 a and thesecond branch pad 140 a are provided with along notch 180 a and ashort notch 200 a to form the longnon-sealing line 18 and the shortnon-sealing line 20. The linear heater includes aninternal line 40 b forming theinside sealing line 4, anenhanced line 220 b forming theenhanced sealing line 22, and first andsecond branch lines branch sealing lines - With such a configuration, the heat sealing mould is mounted on the heat sealing device through the same method of the typical pouch manufacturing method to manufacture the duplex pouch of the present invention.
-
FIG. 7 shows a process for manufacturing the duplex pouch of the present invention. Two piled films forming a pouch are provided between the two heat sealing moulds 10 a and 10 b, and the sealing area is heated at a temperature in a range of 200-275° C. such that the films are primarily heat-sealed. - The first and
second chambers chambers - A nozzle N is inserted through the non-sealed portion to inject a liquid content to be stored, and the non-sealed portion is secondarily heat-sealed while filling nitrogen gas at the end of the injection of the liquid contents to prevent degeneration of the liquid content as necessary.
- For convenience of description, the liquid content injection and the secondary heat-sealing processes are separated in
FIG. 7 , but when the liquid content injection is finished and the nozzle N is ejected, the twomoulds - The heat-sealing mould for manufacturing the duplex pouch of the present invention is not limited to the structure of
FIG. 6 . That is, as shown inFIG. 8 , in the heat-sealing mould 10 b, along heat sink 180 b and ashort heat sink 200 b may be provided at portions extended to thefirst branch line 120 b and thesecond branch line 140 b respectively extended from theinternal sealing line 40 b and theenhanced line 220 b to thereby prevent the corresponding portions from being melted during the heat-sealing process. - In addition, the
non-sealing portion 16 provided in the pressure-openable portion 10 of the duplex pouch of the present invention may be provided in plural, and the plurality of non-sealing portions can more completely block the first andsecond chambers - While this invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
