Description

Vessel for packing coffee and coffee packaging device therefor {Vessel for packaging coffee and coffee packaging machine therefor}

The present invention relates to a coffee packaging vessel that can be used to package a predetermined amount of coffee beans or powder, and a coffee packaging device for sealing and packing the coffee beans, and more particularly, to automatically and automatically store a certain amount of coffee by nitrogen filling. The present invention relates to a coffee packaging vessel that can be packaged and provided, and a coffee packaging apparatus therefor.

As coffee consumption increases, various types of coffee are sold to suit consumers' tastes. In addition to instant coffee, which can be directly consumed by adding hot water, coffee beans or ground coffee powders that can be extracted using a coffee machine or an extraction device are packaged and sold in various forms.

 Of the coffee beans and powdered coffee, it is important to preserve the aroma and flavor of the beans as it is, it is necessary to be more careful in handling. That is, since they are usually roasted and provided to consumers without any additional processing, there is a problem that storage or distribution is relatively difficult, such as easily oxidized and rotted when exposed to air. Currently, this problem is solved by sealing a container to minimize contact with air. There are various packaging methods. For example, a vacuum packaging method or a nitrogen packaging method (eg, Republic of Korea Patent Registration 10-1075093) for filling with nitrogen is known.

However, the shape and size of packaging containers are varying according to various factors such as changing consumers' preferences, development of new extraction devices, and changes in coffee consumption patterns. Accordingly, other problems are difficult to apply such packaging methods. . In particular, the nitrogen-filled packaging method has an advantage of greatly increasing the shelf life compared to other packaging methods, but due to the complexity of the method of releasing air and substituting with nitrogen and the need for a device for enabling the packaging, etc. There was also a difficult problem to apply.

1 to 5, the coffee packaging vessel 10 according to the present invention has a structure in which a shell protruding outwardly is formed on a film, and the shell is formed of the film [first film 10a and first). 2 film (10b)] accommodating space to accommodate coffee between the shell (ie, the first shell (11a) and the second shell (11b)-see Figs. 2, 4 and 5) facing each other It is supposed to make In particular, the coffee packaging vessel 10 is formed by joining different films to the face-to-face, but only a portion of the shell periphery is joined, and an inlet portion (entrance 13) into which the space between the shells is opened. Therefore, it is possible to fill the space between the shell and the like through the inlet 13 and the subsequent nitrogen substitution process can be easily carried out.

That is, the coffee packing vessel 10 is formed in the form of a semi-finished product in which only a portion of the film around the first shell 11a and the second shell 11b facing each other is bonded. In particular, apart from the shell joint 12 formed by joining a portion around the first shell 11a and the second shell 11b, the space between the films is left open. Or it is a structure which can seal all in the desired form. For example, when the inlet portion 13, which is a space between the shell joint portion 12 around the first shell 11a and the second shell 11b, is joined, the first shell 11a and the second shell 11b are joined. Although the periphery of is completely sealed, the inner space therebetween can be blocked from the outside, but if only the outer periphery of the film is bonded without the inlet 13 bonded, the inner space of the outer joint (see 16 in Figure 6) Is blocked from the outside but the pair of the first shell (11a) and the second shell (11b) located therein may be formed to be able to communicate with each other through the respective inlet (13). By using the characteristics of the coffee packaging vessel 10 it can be packed by filling the nitrogen in a pair of different shells very conveniently. The specific charging method will be described later in more detail.

Coffee packaging vessel 10 according to the present invention is specifically configured as follows. The coffee packing vessel 10 overlaps the first film 10a and the other surface of the first film 10a having the first shell 11a protruding from one surface thereof, and face the first shell 11a. A second film 10b having a second shell 11b protruding convexly opposite the first shell 11a at a viewing position, a first around the first shell 11a and the second shell 11b facing each other; The shell joint portion 12 formed by bonding a portion of the film 10a and the second film 10b to each other, and the first film 10a and the second film 10b between the shell joint portion 12 are formed in an unbonded gap. The inlet part 13 which communicates the internal space between the 1st shell 11a and the 2nd shell 11b which were divided by the shell joint part 12 with the outside, and the 1st shell 11a and the 2nd shell 11b. The gas inlet and outlet 14 formed through the at least one of the first film 10a and the second film 10b adjacent to the inlet 13 is disposed on the outside thereof. According to an embodiment of the present invention, a plurality of pairs of the first shell 11a and the second shell 11b facing each other are arranged at different positions, and the first shell 11a and the second shell 11b are arranged. A protrusion 15 protruding adjacent to the inlet 13 from at least one of the first film 10a and the second film 10b is formed on the outside to form the first film 10a and the second film 10b. The adhesion of can be prevented. Hereinafter, the coffee packaging vessel 10 will be described in more detail through an embodiment of the present invention.

Both the first film 10a and the second film 10b may be formed of a flexible material. The first film 10a and the second film 10b may be formed of one or more materials, and the materials may include a soft plastic, a metal material having plasticity, and the like. A coating layer made of a resin may be formed on the surfaces of the first film 10a and the second film 10b. The first film 10a and the second film 10b may be formed in various ways. As shown in FIG. 2, the first film 10a and the second film 10b may be formed in a plate or sheet shape, and a part of the first film 10a and the second film 10b may be bonded to each other in a form that overlaps with each other. The first film 10a and the second film 10b may be formed in sizes corresponding to each other, and the overall size may be appropriately changed as necessary. If the size of the film is increased, the number of shells formed in the film may be increased.

One surface of the first film 10a is formed with a convexly protruding first shell 11a, and the second film 10b has the other surface of the first film 10a on which the first shell 11a is not formed. Nested in At the position facing the first shell 11a of the second film 10b, a second shell 11b protruding convexly opposite to the first shell 11a is formed to form the first shell 11a and the second shell. The 11b are in contact with each other to form a receiving space therebetween. Each of the first shell 11a and the second shell 11b may be formed by convexly protruding portions of the first film 10a and the second film 10b from each other, for example, to have a curved shape. Can be. When combined with each other, the first shell 11a and the second shell 11b may be formed of a three-dimensional surface that forms a spherical surface, an ellipsoidal surface (for example, a three-dimensional surface such as a rugby ball shape), or other polyhedrons. It is possible to form a corresponding receiving space of various types therein accordingly. The first shell 11a and the second shell 11b may be formed in a symmetrical shape, and in particular, may be formed in the shape of an ellipse. At this time, the shape of the ellipse does not mean a simple two-dimensional plane shape, for example, a three-dimensional rotating body formed by rotating an ellipse on the two-dimensional plane about a long axis (for example, may be a shape such as the above-described rugby ball). It can mean the shape of). The first shell 11a and the second shell 11b may be formed in such a characteristic shape to fill coffee in the inner accommodating space.

That is, the pair of the first shell 11a and the second shell 11b facing each other functions as a kind of container for filling coffee in the inner space. A pair of the first shell 11a and the second shell 11b may be arranged side by side on the film as shown, each having the function of an independent container to independently receive a certain amount of coffee. According to an embodiment of the present invention, a specific number of first shells 11a and second shells 11b are illustrated, but the number of shells may be increased as needed.

The pair of the first shell 11a and the second shell 11b are kept in close contact with each other in a position facing by the shell joint 12. The shell joint 12 is formed by joining portions of the first film 10a and the second film 10b around the first shell 11a and the second shell 11b facing each other (see FIGS. 1 and 3). ). As shown, the shell joint portion 12 has a structure surrounding the pair of the first shell (11a) and the second shell (11b) facing each other from the bottom and the top portion is kept open without bonding. Since the shell joint part 12 is formed along the circumferences of the first shell 11a and the second shell 11b, the shell joint part 12 may have a shape corresponding to the outer surfaces of the first shell 11a and the second shell 11b. The shell joint 12 may be, for example, a portion of the first film 10a and the second film 10b that are melted by heat and bonded to each other (even if the film includes a plastic material or a metal material, the resin may be formed on the surface thereof). If there is a coating layer made of a molten method can be bonded). The shell joint part 12 may be formed by a thermal bonding method, but it is not necessary to be limited as such, and as long as the shell joint part 12 can be fixed by bonding a part of the first film 10a and the second film 10b. It may also be formed in another manner (eg, using an adhesive).

The first shell 10a and the second shell 11b partitioned by the shell joint portion 12 by a gap in which the first film 10a and the second film 10b are not bonded between the shell joint portions 12. An inlet portion 13 is formed which communicates the internal space between the outside (see FIGS. 1 and 3 to 5 and the cross-sectional view of FIG. 7). The inlet 13 can be formed in all pairs of each shell that are joined by the shell joint 12. The inlet portion 13 is an empty space in which no shell joint 12 is formed around the first shell 11a and the second shell 11b, and is formed between the first shell 11a and the second shell 11b. It acts as a kind of passageway that communicates internal space with the outside. The size, the open shape, and the like of the inlet part 13 can be changed in correspondence with the size and shape of the shell joint 12. Through the inlet portion 13, coffee powder, etc. can be introduced into the inner accommodating space between the first shell 11a and the second shell 11b. Can be. After nitrogen is filled with coffee in the internal space between the first shell 11a and the second shell 11b through the inlet 13, the inlet 13 is joined to form the first shell 11a and the first shell 11a. The entirety of the two shells 11b can be completely sealed.

Outside the first shell 11a and the second shell 11b, a gas inlet and outlet 14 penetrating at least one of the first film 10a and the second film 10b is adjacent to the inlet 13. Is formed. The gas inlet and outlet 14 may be formed in both the first film 10a and the second film 10b. In such a case, the gas inlet and outlet 14 may be disposed to face each other at a position corresponding to each other. As described above, the gas inlet and outlet 14 is the only passage that communicates the inside and the outside of the outer joint part (see 16 in FIG. 6) when the outer edges of the first film 10a and the second film 10b are bonded together. 13 is also possible to communicate with the outside through the gas inlet and outlet (14). That is, when the outer edges of the first film 10a and the second film 10b are bonded to each other, the inlet part 13 may communicate with the outside through the gas inlet and outlet 14. Therefore, the air filled in the internal space between the first shell 11a and the second shell 11b can be discharged to the outside through the gas inlet and outlet 14 along the inlet 13, and conversely, nitrogen gas is also supplied to the gas inlet and outlet. It can be injected into (14) and filled into the internal space between the first shell (11a) and the second shell (11b) through the inlet portion 13 communicated with it. In particular, when a plurality of pairs of the first shell 11a and the second shell 11b facing each other are arranged in different positions as in the present embodiment, a plurality of inlet portions 13 and a plurality of pairs corresponding to each pair are arranged. The two gas inlets and outlets 14 may be in communication with each other to discharge air to different gas inlets and outlets 14 or to perform different roles of injecting nitrogen. That is, at least one of the plurality of gas inlet / outlets 14 can gas in and out in the opposite direction to the rest. In this case, since the plurality of inlets 13 can communicate with the plurality of gas inlets and outlets 14, air can be discharged from the plurality of inlets 13 through one gas inlet and outlet at a time, and vice versa. Even if the nitrogen gas is injected through the gas inlet and outlet 14, the nitrogen gas may be distributed to the plurality of inlets 13 communicated with the gas inlet and outlet 14 to fill the internal space between the pair of shells. Specific manners in this regard will be described later in more detail.

Meanwhile, protrusions 15 protruding adjacent to the inlet 13 may be formed outside the first shell 11a and the second shell 11b. The protruding portion 15 protrudes adjacent to the inlet portion 13 from at least one of the first film 10a and the second film 10b and is disposed between the first film 10a and the second film 10b. It interposes and prevents the contact | adherence of the 1st film 10a and the 2nd film 10b (refer FIG. 4 and FIG. 5). The protrusion 15 may also be formed on both sides of the first film 10a and the second film 10b, and in this case, may be disposed at different positions so as not to face each other. In particular, the protrusion part 15 may serve to maintain an open state without closing the inlet part 13 at a point adjacent to the inlet part 13, so that the process of gas in and out may be performed more smoothly. The protruding portion 15 may be disposed adjacent to the inlet portion 13 but not placed on a movement path through which the gas or coffee passes through the inlet portion 13. For example, the gas inlet and outlet 14 may be formed by penetrating a portion of the film on the upper portion of the inlet portion 13, and the protrusion 15 may be formed on the left side of the gas inlet and outlet portion 14 and / or not on the upper portion of the inlet portion 13. Or it may protrude at a point corresponding to the right side (see FIG. 1, etc.).

In the present embodiment, the first shell 11a and the second shell 11b may be formed in the shape of an ellipse as described above, and in particular, the inlet 13 may be formed in the shape of an ellipse located at the distal end of the long axis. Can be. That is, the inlet part 13 may be formed at the upper end side of the first shell 11a and the second shell 11b having an ellipse shape formed long in the vertical direction, for example, as shown in each drawing. The inlet portion 13 can be opened relatively short in the minor axis direction of the ellipse and can be opened in the shorter direction in which the fluctuation of the diameter is relatively small, so that the inlet 13 can be easily opened into the inner space along the longitudinal direction of the shell from the inlet part 13 to the lower end. Coffee can be added or gas can be charged. In addition, the shape of the shell is formed in an oval three-dimensional shape, such as coffee beans as a whole can give a visual satisfaction to the buyer. Finally, after the nitrogen gas filling is completed, each pair of shells joined and sealed around, for example, may be cut out of the film at the boundary of the shell joint 12 and supplied to the buyer individually. Hereinafter, the nitrogen filling process of the coffee packaging vessel 10 will be described in more detail with reference to FIGS. 6 and 7.

6 is a perspective view illustrating a state in which an outer junction is formed in the vessel of FIG. 1, and FIG. 7 is a cross-sectional view illustrating the inside of the vessel of FIG. 6 in which the outer junction is formed.

The coffee packing vessel 10 may initially be provided in a state as shown in FIG. 1 and in such a state between the first shell 11a and the second shell 11b via an open inlet 13. You can put coffee in the space. Although not specifically illustrated, for example, the nozzle of the injection device for injecting the coffee powder or the like may be directed toward the inlet portion 13 of the shell upper portion to inject coffee into the inner receiving space formed between the shells at the top. After a certain amount of coffee (not shown) is introduced into the inner spaces of the pairs of the shells, the film outer portion of the coffee packing vessel 10 is bonded as shown in FIGS. 6 and 7.

That is, after the coffee is put into the inner receiving space between the first shell (11a) and the second shell (11b), while the inlet portion 13 remains open, the first film (10a) and the second film ( 10b) this outline is joined. In this case, the outer edge may mean a boundary of the film surrounding the shell so as to accommodate the entire shell formed in the film, which may be, for example, an edge of the film. Accordingly, the outer joint 16 is formed on the edge portion surrounding the outer edges of the first film 10a and the second film 10b. Since the outer portion of the film is bonded by the outer portion 16, the inner space of the outer portion 16 is blocked from the outside and communicates with the outside only through the gas inlet and outlet 14 (see FIG. 7). At this time, since the inlet 13 inside the outer joint 16 remains open, the plurality of gas inlets and outlets 14 can communicate with the plurality of inlets 13 corresponding to each pair of shells as described above. Therefore, the air is sucked out of the plurality of inlets 13 through the gas inlet and outlet 14 at a time and discharged to the outside, or the plurality of inlets 13 inversely with the nitrogen gas introduced through another gas inlet and outlet 14. Can be dispensed. That is, at least one of the plurality of gas inlets and outlets 14 may allow gas of different components to enter and exit in the opposite direction to the other (see FIG. 6). For example, when the pair of the first shell 11a and the second shell 11b is formed in three pairs as in the present embodiment, the gas at the center side among the three gas inlets and outlets 14 arranged at corresponding positions thereof is formed. While injecting nitrogen gas (see A in FIG. 6) into the inlet and outlet 14, the inside and the outside of the gas inlet and outlet 14 can be sucked out and discharged to the outside (see FIG. 6B). Through this, the nitrogen gas replacement operation for filling nitrogen while extracting air from each of the inner spaces of the pair of shells can be performed very quickly at the same time (see FIG. 7).

This operation can be proceeded to the coffee packaging apparatus of the present invention to be described later, and when the nitrogen gas replacement is completed can be individually sealed around the pair of each shell with a bonding head that operates independently of each other formed in the coffee packaging apparatus. Thereafter, the circumference of each sealed pair of shells may be cut at the boundary of the shell joint 12 as described above to form a coffee-packed product formed in an ellipse shape and filled with a nitrogen filling method therein. . Hereinafter, a coffee packaging apparatus according to the present invention will be described in detail with reference to FIGS. 8 to 18.

It consists of the structure which can seal, extract gas, and replace. In particular, based on the pair of base plate 101 and the pressing plate 102, which can bond the film outside of the coffee packing vessel 10, it operates individually in the grooves formed on the inside thereof, and the circumference of each pair of shells. It consists of a structure including a bonding head 112 to be in close contact with each other. In addition, the space is opened even when pressurized such that the gas replacement hole 111 communicating with the gas inlet and outlet (see 14 in FIGS. 1 to 3) and the inlet (see 13 in FIGS. 3 to 7) are kept open.

The coffee packing vessel 10 described above may be inserted and compressed between the base plate 101 and the pressure plate 102 (see FIG. 11), and the base plate 101 and the pressure plate 102 may each be a coffee packing vessel. Abut one surface and the other surface of (10), respectively. Each side of the coffee packaging vessel 10 refers to a surface on which the first shell 11a and the second shell 11b of the first film 10a and the second film 10b are protruded. Since 11a) and the second shell 11b protrude to opposite sides, when the first shell 11a is directed toward the base plate 101, the second shell 11b is directed toward the pressing plate 102. The reverse is also possible if the direction changes. The base plate 101 and the pressure plate 102 are arranged in a vertical direction, and the coffee packing vessel 10 can be squeezed upright in a vertical direction therebetween. The support 104 of the lower portion of the coffee packaging apparatus 100 may be connected to a support plate (see 105 of FIG. 9) for supporting the base plate 101 and the pressure plate 102 to maintain this arrangement. Between the base plate 101 and the pressure plate 102 is provided with a plurality of guide pins 115 for adjusting the position surrounding the coffee packing vessel 10 so that the coffee packing vessel 10 is connected to the base plate 101. It is possible to prevent the separation between the pressing plate (102).

At least a portion of the coffee packaging apparatus 100 may be covered and protected by the housing 103, and a driving unit for driving the pressing plate 102 may be disposed inside the housing 103 (see FIGS. 8 and 9). . The pressing plate 102 may slide in the horizontal direction along the sliding bar 119 (see FIGS. 9 to 11). On the other hand, the base plate 101 maintains a fixed state, and instead, the bonding head 112 inside thereof may move in a direction parallel to the pressing plate 102. The pressing plate 102 may be slidably coupled to the sliding bar 119 connected in a horizontal direction between the support plate 105 and the base plate 101. The support plate 105 may be provided with a pressure cylinder 125 for sliding the pressing plate 102 and may be fixed by connecting the pressure cylinder 125 and the pressure plate 102 with the connection block 126.

The pressing plate 102 may be coupled to the sliding bar 119 coupled to the support plate 105 through the sliding groove 123. have. A plurality of sliding bars 119 may be penetrated to each corner portion of the pressing plate 102 to guide the sliding movement of the pressing plate 102 more stably. One end of the pressure cylinder 125 is fixed to the support plate 105 and the other end is connected to the pressure plate 102 through the connection block 126. Accordingly, the pressure cylinder 125 may be expanded and contracted to move the pressure plate 102 along the sliding bar 119.

The pressing plate 102 is formed by indenting the second groove portion 120 in contact with the coffee packing vessel 10. The second groove 120 corresponds to the first shell (see 11a of FIGS. 1 to 7) or the second shell (see 11b of FIGS. 4, 5 and 7) protruding outward from the coffee packing vessel 10. It is formed in a shape to accommodate the first shell (11a) or the second shell (11b). For example, the second groove 120 may be formed as an elliptical groove corresponding to the shape of the shell described above, for example, to accommodate each shell individually. The second groove portion 120 is indented to a sufficient depth to accommodate the aforementioned shells, and even though the pressing plate 102 is in close contact with the base plate 101, the shells can be accommodated and protected therein so that each shell maintains its original shape. (See FIG. 15). A plurality of second grooves 120 may be arranged side by side corresponding to the number of shells arranged on the outer surface of the coffee packing vessel 10.

The heat generating module 124 for heating the pressure plate 102 is disposed inside the pressure plate 102. The heating module 124 may be formed of, for example, a heating wire, and may adjust the amount of heat by using a controller (not shown) for controlling the amount of current flowing into the heating wire. The heating module 124 may be disposed in a plurality of disperse positions at different positions inside the pressure plate 102. The pressure plate 102 may be formed of a material that can be heated by the heat generating module 124, and may include a metal material or a ceramic material in consideration of thermal conductivity or heat storage amount.

One side of the pressing plate 102 may be formed with a guide pin insertion groove 122 into which the above-described guide pin 115 is inserted. The guide pin insertion groove 122 penetrates in the sliding direction of the pressure plate 102 so that the guide pin 115 may change even when the distance between the pressure plate 102 and the base plate 101 changes when the pressure plate 102 moves. The guide pin 115 may be accommodated therein so as not to be separated (see FIG. 15). Since the guide pin insertion groove 122 is installed to face the guide pin 115, the position may be changed corresponding to the position of the guide pin 115.

A gas flow groove 121 having a long groove shape may be formed at a position adjacent to the second groove 120 of the pressing plate 102. The gas flow groove 121 may extend in a direction connecting the gas flow grooves 121 to a position corresponding to the gas inlet and outlet 14 of the coffee packing vessel 10. For example, the gas flow groove 121 may be formed in the form of a long groove extending in the horizontal direction at a position corresponding to the gas inlet and outlet 14. When the pressure plate 102 is in close contact with the base plate 101, the gas flow groove 121 connects different gas replacement holes 111 at opposite sides of the gas replacement hole 111 of the base plate 101 so that the gas is external. It can also play a role in cracking down on leaks.

The structure of the base plate 101 will be described in more detail with reference to FIGS. 13, 14, and 15.

The base plate 101 is formed to be wider than the first shell 11a or the second shell 11b on the surface in contact with the coffee packing vessel 10 to accommodate the first shell 11a or the second shell 11b. 1 groove 110 is formed in a structure indented. For example, the first groove 110 may be formed in a size corresponding to the outer joint portion (see 16 of FIGS. 6 and 7) of the coffee packaging vessel 10 described above, and the coffee packaging vessel 10 may be formed therein. It can be formed in a size that can accommodate all of the plurality of shells arranged on one side. The first groove 110 also serves to protect the shell protruding to the outside of the coffee packaging vessel 10 when the base plate 101 and the pressure plate 102 are in close contact with each other to protect the first plate 110 from being deformed. It is wider than 120 and the shape does not need to be formed corresponding to the shape of the shell (see Fig. 15). The base plate 101 may be formed of a material including a metal material. The base plate 101 may have a sliding bar fixing groove 116 formed at a position corresponding to the sliding bar 119 in which the pressure plate 102 slides, and may be coupled to the sliding bar 119.

A bonding head 112 is formed inside the first groove 110 of the base plate 101. Bonding head 112 is formed in a shape corresponding to the first shell (11a) or the second shell (11b) surrounding the first shell (11a) or the second shell (11b) to accommodate the inside and the base plate 101 Sliding movement is coupled to enable. The bonding head 112 sails the pressing plate 102 inside the first groove 110, and the first film 10a and the second film around the first shell 11a and the second shell 11b. 10b) can be pressed against each other (see FIG. 14). As shown in the first groove 110, a plurality of joining heads 112 may be arranged to be individually movable. A shell joining ring 112a having a shape corresponding to the shell is formed at the end facing the pressure plate 102 of the joining head 112, and a space indented into the joining head 112 from the shell joining ring 112a is shelled. It is possible to form a shell accommodating groove (112c) to accommodate the. The shell receiving groove 112c may be formed at a position substantially corresponding to the second groove portion 120 of the pressing plate 102 (see FIG. 15). The shell bonding ring 112a may be formed, for example, as an elliptic ring and may be coupled along the inner circumferential surface of the bonding head 112 at the distal end of the bonding head 112. The shell bonding ring 112a may be formed of, for example, a material having elasticity.

The joining head 112 may be inserted into the joining head insertion hole 113 formed by being inserted into the first groove 110. On the opposite side of the surface facing the pressure plate 102 of the base plate 101, a bonding head cylinder 118 for driving the bonding head 112, a cylinder support 118b for supporting it, and a cylinder support 118b and a base A support block 117, which is a support structure that is in close contact with the base plate 101 and is supported between the plates 101, may be disposed (see FIG. 13). The joining head drive shaft 118a protruding from the joining head cylinder 118 through the cylinder support 118b is an airtight holding hole 117b and a base plate 101 formed on the airtight holding surface 117a of the support block 117. Through the through-hole 113a formed in the joining head insertion hole 113 in the inner side may be coupled to the shaft coupling groove 112b of the joining head 112 (see FIG. 13). At this time, in particular, the support block 117 may form a structure in close contact with the base plate 101 as a protruding hermetic holding surface 117a and the hermetic holding surface 117b so as not to be exposed to the outside again on the hermetic holding surface 117a. ) May be formed so that gas or the like does not leak between the joining head drive shafts 118a. In particular, a plurality of O-rings and / or gaskets may be installed inside the hermetic holding member 117b to more effectively maintain hermetic sealing.

For example, the first groove 110 may be formed as a wide recessed groove having a rectangular shape (see FIGS. 13 to 15). The base plate 101 is formed with a closed outer ring 114 having a closed shape protruding toward the pressing plate 102 and surrounding the outer portion of the first groove 110. The outer joining ring 114 may be inserted into the fixing groove 114a surrounding the outer portion of the first groove 110 and may be formed as a quadrangular ring corresponding to the circumferential shape of the first groove 110. The outer joining ring 114 protrudes more than the joining head 112 toward the pressing plate 102 (see FIG. 15), so that the outer joining ring when the pressing plate 102 and the base plate 101 are in close contact with each other ( In the shape corresponding to 114, the film outer portion of the coffee packaging vessel 10 may be pressurized first. That is, the outer joint ring 114 surrounds the outer edge of the first groove 110 in a structure for forming an outer joint portion (see 16 of FIGS. 6 and 7) surrounding the film outer portion of the coffee packing vessel 10 described above. And it may be formed in a shape more protruding toward the pressing plate 102 than the bonding head 112. The outer joint ring 114 may also be formed of a material having elasticity.

The guide pin 115 may protrude in the direction of the pressing plate 102 on the outside of the first groove 110 (see FIGS. 13 and 15). The plurality of guide pins 115 are arranged at regular intervals and may be inserted into the guide pin insertion grooves 122 of the pressure plate 102 to be slidably movable. Therefore, the guide plate 115 may be connected between the base plate 101 and the pressure plate 102. By using the guide pins 115, the vessel packaging vessel 10 may be conveniently located in the space between the base plate 101 and the pressure plate 102. The shape of the guide pin 115 is illustrative and can be modified into various shapes that can be connected between the base plate 101 and the pressure plate 102. By properly arranging the plurality of guide pins 115, the coffee packing vessel 10 can be guided very effectively to maintain its position without falling or falling outwards.

Inside the first groove 110, a gas replacement hole 111 communicating with the gas inlet and outlet 14 of the coffee packing vessel 10 is formed therethrough. The gas replacement hole 111 penetrates from the outside of the base plate 101 to the inside of the first groove 110 and may be arranged at a position corresponding to the gas inlet and outlet 14 described above. The gas replacement hole 111 is opened to overlap the gas inlet and outlet 14 of the coffee packing vessel 10 to inject nitrogen into the interior of the coffee packing vessel 10 through the gas inlet and outlet 14 or the coffee packaging vessel 10. The inside air can be sucked out and discharged to the outside. In particular, as described above, the coffee packing vessel 10 has a plurality of pairs of first shells 11a and second shells 11b facing each other arranged at different positions, and a plurality of inlets corresponding to each pair. Since the 13 and the plurality of gas inlet and outlet 14 communicate with each other, the gas may be directly introduced or discharged through the gas inlet and outlet 14 into the gas replacement hole 111 opened to overlap the gas inlet and outlet 14. That is, at least one of the plurality of gas exchange holes 111 corresponding to the gas inlet and outlet 14 may flow the gas in the opposite direction to the rest and allow the gas to flow into and out of the coffee packing vessel 10. That is, as described above, in the case of injecting nitrogen gas into one of the gas inlets and outlets 14 of the coffee packing vessel 10 and discharging air to the outside using the remaining, each gas replacement hole 111 corresponding thereto. ) May serve to inject nitrogen gas in the same way as the gas inlet or outlet 14 or to discharge air to the outside. That is, for example, when nitrogen gas is injected through any one of the plurality of gas replacement holes 111, nitrogen gas is injected into the coffee packaging vessel 10 through the corresponding gas inlet and outlet 14 overlapping therewith. When the air is sucked into the remaining gas replacement hole 111, the air inside the coffee packing vessel 10 may be sucked through the corresponding gas inlet and outlet 14 overlapped therewith and discharged to the outside. On the outside of the base plate 101 connected to the gas replacement hole 111, a gas inlet and outlet portion 111a may be formed to connect an external flow path (not shown) and the gas replacement hole 111, and the gas inlet and outlet portion 111a may be formed. Is formed as a socket and the like easily connected to the pipe can be coupled to the end of the gas replacement hole (111).

The first groove 110 may also include stepped portions 110a and 110b formed of a first plane 110a and a second plane 110b having different heights around the joining head 112 (see FIG. 14). . The stepped portions 110a and 110b may be formed in stages having different heights from each other to more effectively space a portion of the circumference of the bonding head 112 from the surface of the pressing plate 102 inside the first groove 110. That is, the first plane 110a of the stepped portions 110a and 110b is advanced toward the pressing plate 102 so that the first film outside the first shell 11a and the second shell 11b of the coffee packaging vessel 10. 10a and the second film 10b are brought into close contact with each other, and the second plane 110b may be retracted to the opposite side of the pressing plate 102 than the first plane 110a (see FIG. 14). The gas replacement hole 111 may be opened in the second plane 110b of the stepped portions 110a and 110b. The steps 110a and 110b form a space inside the first groove 110 by using the second plane 110b that is retracted to the opposite side of the pressing plate 102, and the space is formed in the above-described coffee packing vessel 10. It may serve to prevent the inlet 13 from being compressed and to keep the protrusion adjacent to the inlet 13 (see 15 of FIGS. 1 to 7) from being deformed. In addition, even if the pressing plate 102 and the base plate 101 are in close contact with each other, the film outside of the coffee packaging vessel 10 is bonded by the above-described outer bonding ring 114 of the plurality of shells located therein. Different inlets 13 may be easily maintained in an open state to have an effect of smooth communication with each other. With this structure, the nitrogen filling and sealing process of the coffee packing vessel 10 as described above can be performed very conveniently and efficiently.

16 to 18 are operation diagrams illustrating a process of packaging by replacing the nitrogen packaging coffee vessel with the base plate, the pressure plate, and the bonding head of FIG.

Hereinafter, the operation of the coffee packaging apparatus will be described in more detail with reference to FIGS. 16 to 18 and FIGS. 9 to 11 where the entire structure of the coffee packaging apparatus is shown.

First, as shown in FIG. 16, the coffee packing vessel 10 is inserted into a space between the base plate 101 and the pressing plate 102. The coffee packing vessel 10 may be inserted such that the first shell 11a side faces the base plate 101 and the second shell 11b side faces the pressing plate 102 or vice versa. . As described above, using the guide pin 115 connected between the base plate 101 and the pressure plate 102, the coffee packaging vessel 10 is conveniently inserted between the base plate 101 and the pressure plate 102. And maintain its position (see FIG. 11).

In this state, the coffee powder (not shown) or the like may be charged into the space between the first shell 11a and the second shell 11b through the inlet 13 of the coffee packing vessel 10. The dose of coffee may be appropriately adjusted in view of the nitrogen filling amount. Although not shown, it is possible to use a nozzle for injecting coffee powder or beans, as described above, it can be placed to the inlet 13 side to inject coffee into the inner receiving space between the shell. After the proper supply is made, the nitrogen filling and sealing work is performed through the subsequent nitrogen gas replacement.

As the first step of the nitrogen filling and sealing operation, as shown in FIG. 17, the pressure plate 102 is brought into close contact with the base plate 101 and the nitrogen gas replacement operation is performed. The pressure plate 102 may be in close contact with the base plate 101 by sliding along the sliding bar 119 by the driving of the above-described pressure cylinder 125 (see FIGS. 9 to 11). When the first shell 11a and the second shell 11b are in close contact with each other, the shell accommodating grooves recessed in the interior of the first groove portion 110 (specifically, the joining head 112 of the first groove portion 110). Inside of the (112c) and the second groove portion 120 is maintained in the shape as it is, the first film (10a) and the first pressed by the outer bonding ring 114 around the first groove (110) Only the outer portion of the two film 10b is bonded. At this time, the above-described heating module (see 124 of FIG. 12) may be operated and the pressing plate 102 may be heated, and the portion where the outer joining ring 114 is positioned is pressed toward the pressing plate 102 to form the outer joining ring 114. The outer edge of the film may be bonded in a shape corresponding to the shape. As a result, the aforementioned outer junction 16 is formed on the coffee packaging vessel 10, and the coffee packaging vessel 10 communicates with the outside only through the gas inlet and outlet 14 as described above.

In particular, the above-described stepped structure (steps 110a and 110b-see FIG. 14) is formed inside the first groove 110, so that the base plate 101 and the pressure plate 102 are in close contact with each other as shown in FIG. 17. By forming a space to prevent deformation of the protrusion 15 and spaced apart between the first film (10a) and the second film (10b) it is possible to maintain the optimum opening state. In addition, since the gas inlet and outlet 14 directly overlaps the gas replacement hole 111 opened to the corresponding point inside the first groove 110, the gas inlet and outlet 14 passes through the gas inlet and outlet 14 through the gas replacement hole 111. The passage structure which is very easy to mutually communicate with the part 13 is formed. In addition, the gas flow groove 121 described above connects the gas inlet and outlet 14 to the pressure plate 102 on the opposite side to prevent leakage of gas to the outside. The nitrogen gas replacement process of injecting and filling (see FIG. 17A) proceeds very smoothly.

At this time, as described above, the gas replacement hole 111 is formed in plural and injects nitrogen gas into the space inside the outer junction portion 16 formed in the coffee packaging vessel 10 with any one of them, and the inner side of the outer junction portion 16 through the rest. The air in the space can be sucked out and discharged to the outside (see FIGS. 6 and 14 A and B). In such a process, the plurality of gas inlets and outlets 14 overlapping each gas replacement hole 111 may serve as a passage through which nitrogen gas is injected or air is discharged. In particular, as described above, the plurality of inlets 13 inside the outer joint 16 may communicate with the plurality of gas replacement holes 111. Nitrogen gas may be simultaneously injected into each of the internal spaces between the first shell 11a and the second shell 11b connected to 13), and air may be removed and replaced with nitrogen gas. In this way it is possible to fill the nitrogen gas in the interior space between each pair of shells the coffee is introduced.

When the process is completed, as shown in FIG. 18, the bonding head 112 inside the first groove 110 is moved toward the pressing plate 102 to bond the entire circumference of the first shell 11a and the second shell 11b. . That is, the final sealing process is performed using the bonding head 112 formed to be individually movable in the direction of the pressing plate 102 inside the first groove 110. Since the plurality of joining heads 112 are individually movable, each of the joining heads 112 can be completely joined to the shell circumference simultaneously or sequentially or in any other manner as necessary. In addition, this sealing process is first bonded to the outer film film of the coffee packaging vessel 10 in the state of injecting nitrogen gas, the space in which the nitrogen gas is injected into the bonding head 112 disposed in each shell (that is, the first Since the inside of the groove portion 110] is independently operated, the nitrogen injection is interrupted or the pressure is reduced in the sealing process. In this way, the interior spaces between the pairs of shells can be filled with nitrogen and sealed. Then, if necessary, it is possible to cut around the pair of sealed shells to separate only the oval-shaped nitrogen-filled shell portion from the film, which can be sold or distributed as a individually packaged coffee packaged product. In this manner, the coffee packaging vessel 10 may be provided by being sealed in a nitrogen gas substitution method very conveniently.
