To this end, the paste discharging container according to the invention is characterized by comprising a housing having a first female screw portion on the lower inner surface thereof, an actuator having a first male screw portion coupled to the first female screw portion on the outer surface thereof and being inserted into the inside of the housing for discharging the paste to the outside, and an upper cap removably coupled to the upper portion of the housing.

Description

CONTAINER FOR DISCHARGING PASTE THEREFROM
Technical Field The present invention relates to a container for discharging paste therefrom, and more particularly to a container for discharging a desired amount of paste theref om, completely emptying the container, and discharging two or more sorts of paste simultaneously without being mixed before being discharged as required.
Background Art
The term paste is defined as substance such as toothpaste or ointment, and a paste discharging container as the container for containing and then discharging the paste therefrom.
Fig.20 shows a longitudinal section of a conventional paste discharging container. As shown in Fig.20, the conventional paste discharging container comprises a housing 10' of flexible material and an upper cap 80' removably coupled to the upper portion of the housing
10'.
When the paste A is discharged from the conventional paste discharging container, the body of the container is pressed to discharge the paste A while the cap 80' is open.
However, when the paste A is discharged in the manner described above, pressure is concentrated on a portion of the container, thus the paste A is pushed to other portions where pressure is not applied, and some of paste A in some regions of the container may not be discharged to the outside.
Also, when a user rolls the end of the container or applies pressure to the body of the container in order to discharge the paste, he cannot efficiently control the specified amount of the paste to be discharged.
In addition, since the conventional paste discharging container can contain only one sort of paste A in the housing 10', the container is not suitable for mixing two or more sorts of paste while discharging the paste.
In order to address such problems, a paste discharging container with a partition therein was designed.
Fig.21 shows a longitudinal section of another conventional paste discharging container. As shown in Fig.21, the conventional paste discharging container has a partition 200 inside the housing 10' to contain two sorts of pastes A and B. When the paste combination of A and B in the container is discharged, however, pressure is concentrated on a portion of the container as in the conventional paste discharging container shown in Fig.20, thus the paste combination of A and B is likewise pushed to other portions where pressure is not applied, and some paste combination of A and B in the container may not be discharged to the outside.
Furthermore, when the two sorts of pastes A and B must be mixed by a specified amount, pressure is applied to only a portion of the container and thus a required amount of the pastes of A and B cannot be discharged simultaneously. Also, it is hardly possible to discharge all of pastes A and B in the container therefrom.
Disclosure of Invention
The invention is designed to solve the above problems. Therefore, it is an object of the present invention to provide a paste discharging container from which a desired amount of paste can be discharged, thereby ultimately leaving no paste in the container. It is another object of the invention to provide a paste discharging container from which two or more sorts of paste can be simultaneously discharged, such that a desired amount of paste can be discharged, thereby ultimately leaving no paste in the container.

Best Mode for Carrying out the Invention
Hereinafter, the preferred embodiments according to the invention are detailed with reference to the accompanying drawings. It should be noted that like components are denoted by like characters while they are depicted in different drawings. When describing the invention, the description may be omitted where it has been decided that a detailed description about known functions or configurations will make the subject of the invention unnecessarily obscure.
Fig.l shows a longitudinal section of a paste discharging container according to a first embodiment of the invention. As shown in Fig.l, the paste discharging container comprises a housing 10, an actuator 20, a lower cap 90 and an upper cap 80.
The housing 10 is a body to contain paste A, and on the lower inner surface of the housing 10 is formed a first female screw portion 12. It is preferred to construct the housing 10 with rigid material so that it may not deform when used.
The actuator 20 is a driving means for moving the paste A upward, and comprises a sloping surface 22a, an actuator projection 22b, a first male screw portion 25, and a third female screw portion 23.
The sloping surface 22a corresponds to the sloping surface 14 of the housing 10 formed on the upper portion of the housing 10, and the actuator projection 22b corresponds to the neck 15 of the housing 10, so that the actuator 20 can move closely to the upper end of the housing 10.
The actuator 20 is inserted into the lower end of the housing 10 by screwing the first male screw portion 25 into the first female screw portion 12. Therefore, by moving forward the actuator 20 through rotation, a specified amount of the paste A can be discharged.
The lower cap 90 is a component removably coupled to the lower portion of the actuator 20. On the outer surface of the lower cap 90 is formed a third male screw portion 92 coupled to the third female screw portion 23 of the actuator 20.
Accordingly, it is possible to place small articles that may be lost easily inside of the actuator 20 and then to screw the lower cap 90 into the lower portion of the actuator 20 when using the paste discharging container. The lower cap 90 can be unscrewed in order to use the small articles.
The upper cap 80 may be a general cap used for a conventional paste discharging container. Fig.2 shows a longitudinal section of a paste discharging container according to a second embodiment of the invention.
As shown in Fig.2, the paste discharging container according to the invention comprises a housing 10, a piston 50, an actuator 20, a lower cap 90 and an upper cap 80.
The piston 50 is a means for discharging the paste A contained in the housing 10, and is tightly inserted into the inside of the housing 10 and movable upward and downward.
The piston 50 comprises a sloping surface 52 and a piston projection 54.
The sloping surface 52 of the piston 50 is formed to correspond to the sloping surface 14 of the housing 10 provided on the upper portion of the housing 10. The piston projection 54 is formed to correspond to the neck 15 of the housing 10, so that the piston 50 can move closely to the upper end of the housing 10.
The actuator 20 is a driving means for moving the piston 50, and has a first male screw portion 25 on the outer surface thereof and a third female screw portion 23 on the lower inner surface thereof.
As the first male screw portion 25 is screwed into the first female screw portion 12, the actuator 20 is inserted up to the piston 50.
After the actuator 20 is inserted up to the piston 50, the user can move forward the actuator 20 through rotation to discharge a specified amount of paste A. The housing 10, the lower cap 90 and the upper cap 80 can be configured equivalent to those of the embodiment shown in Fig.l.
Fig.3 shows a longitudinal section of a paste discharging container according to a third embodiment of the invention.

The housing 10 and the upper cap 80 are configured equivalent to those of the embodiment of Fig.l, and the external cap 100 is configured equivalent to that of the embodiment of Fig.3.
Therefore, as the external cap 100 connected to the actuator 20 is rotated by given pitches along the housing scale marks 16, the actuator 20 is rotated along with the external cap 100 simultaneously to discharge specified amounts of paste A and B contained in the housing 10 and the auxiliary container 40, respectively.
As the actuator 20 moves upward in the container, the auxiliary container 40 made of rigid material is inserted deeply along the guiding groove formed between the auxiliary actuator portion 21a and the main actuator portion 21b.
The actuator 20 moves up to the upper end of the housing 10, and the auxiliary container 40 is inserted into the end of the actuator 20, so that the paste A and B can be completely discharged from the container.
Alternatively, it is possible to form and to install more than one auxiliary container 40 depending on the number of sorts of paste to be mixed, in the housing 10 in the paste discharging container according to the invention. Fig.7 shows a longitudinal section of a paste discharging container according to a seventh embodiment of the invention. As shown in Fig.7, the paste discharging container according to the invention comprises a housing 10, a piston 50, an auxiliary container 40, an actuator 20, a lower cap 90 and an upper cap 80.

A second male screw portion 13 is formed on the lower outer surface of the housing 10, and the housing scale marks 16 are on the outer surface of the housing 10, so that a desired amount of paste A 16 can be discharged by driving the actuator 20 according to the scale marks.
The piston 50 comprises a sloping surface 52, a piston projection 54, and a piston mating portion 56. The sloping surface 52 of the piston and the piston projection 54 are configured equivalent to those shown in Fig. 2.
The piston mating portion 56 is coupled to the actuator mating portion 29 formed on the actuator 20, and formed to be flush with the inner lower end of the actuator 20. As shown in Fig.13, the piston mating portion 56 is formed to have a recess, and the actuator mating portion 29 projects to be complementary to the recess.
As shown in Fig.14, the piston mating portion 56 may project and the actuator mating portion 29 may thus have a recess to be complementary to the projection. The actuator 20 is a driving means for moving the piston 50, and has a fifth female screw portion 26 and a sixth female screw portion 27 on the inner surface thereof.
The fifth female screw portion 26 of the actuator 20 and the second male screw portion 13 of the housing 10 are screwed, and a desired amount of paste A can be thus discharged while moving the actuator 20 through rotation along the housing scale marks 16. The tightly coupling member 110 is a component applied to the outer surface of the housing 10 for sealing up gaps formed between the housing 10 and the actuator 20.
On the outer surface of the tightly coupling member 110 is formed a sixth male screw portion 112 which screws into the sixth female screw portion 27 of the actuator 20.
As the actuator 20 is driven, the tightly coupling member 110 is also driven simultaneously.
Also, the tightly coupling member 110 may be of such an elastic material as rubber. The upper cap 80 is configured equivalent to that of the embodiment shown in Fig.1. Figs.14, 15 and 16 show longitudinal sections of a paste discharging container according to twelfth, thirteenth and fourteenth embodiments of the invention.

The housing 10 has a second male screw portion 13 on its lower outer surface, and housing scale marks 16 on the outer surface thereof. The housing 10 also is provided with a support member 18 for coupling the separating member 60 thereto.
The separating member 60 is a component to divide the inside of the housing 10 into two or more chambers for containing two or more sorts of paste, and the number of the separating members 60 depends on the number of the sorts of the paste to be contained.
As shown in Fig.16, the actuator mating portion 29 may be configured to extend into the connecting member 76.
Fig.17 shows a longitudinal section of a paste discharging container according to a fifteenth embodiment of the invention
As shown in Fig.17, the paste discharging container according to the invention has a first indicating line 19 marked on the outer surface of the housing 10, and second indicating lines 114 are spaced apart on the outer surface of the tightly coupling member 110.
Since the actuator 20 is in screw-engagement (not shown) with the tightly coupling member 110, the tightly coupling member 110 is caused to mate when the actuator 20 is rotated. The tightly coupling member 110 is rotated by a specified angle along the outer surface of the housing 10, with reference to the first indicating line 19.
Accordingly, in order to discharge a small amount of paste corresponding to no more than one pitch of the housing, the actuator 20 is rotated to move the second indicating lines 114 with reference to the first indicating line 19. Figs.18a to 18d show cross sections of housings 10 of the paste discharging containers according to the embodiments of the invention.
As shown in Figs. 18b and 18d, the separating member 60 may be shaped like a partition, and more than one separating member 60 may be provided depending on the number of sorts of paste to be contained in the housing 10. As shown in Figs.18a and 18c, the separating member 60 can form more than one separate container to define more than two chambers.
Referring back to Fig. 14-16, the piston assembly 70 comprises a piston member 72 and a connecting member 76 as shown in Fig.16.
The piston member 72 is a removable component tightly inserted into the inside of each chamber, and two or more piston members may be provided to the piston assembly 70.
The connecting member 76 is a component formed on the lower ends of the piston members 72 to support the piston members 72, and has a mating portion 77.
As shown in Fig.14, the connecting member 76 may be formed integrally with the piston member 72, or the connecting member 76 and the piston members 72 may be connected as shown in Fig.15.
The mating portion 77 is coupled to the actuator mating portion 29 formed on the actuator 20, and may be formed to be flush with the lower inner end of the actuator 20 as shown in Fig.12. As shown in Fig.14, a projection may be formed on the mating portion 77, and then the actuator mating portion 29 may have a recess corresponding to the projection. Alternatively, as shown in Fig.15, the mating portion 77 may have a recess and then the actuator mating portion 29 may have a projection corresponding to the recess.
The actuator 20 and the tightly coupling member 110 are configured equivalent to those of the paste discharging container according to the embodiments of Figs.12 and 13, and the upper cap 80 is configured equivalent to that of the embodiment of Fig.l.
Fig.19 shows an operation of the paste discharging container according to embodiments of the invention.
As shown in Fig.19, while the piston members 72 inserted into each chamber are raised as the piston assembly 70 is moved by means of the interaction of the fifth female screw portion 26 of the actuator 20 and the second male screw portion 13 of the housing 10, the paste contained in the chambers is discharged outside, respectively.
The paste discharging containers according to the invention have the piston 50 or the piston member 72 which is inserted into the chambers formed by the separating member 60, and are shaped correspondingly to the shape of the chambers.
As described above, a paste discharging container according to the invention can discharge a specified amount of paste by controlling the movement of the actuator relative to the housing.
By constructing a piston, a piston member and an actuator to correspond to the upper portion of the housing, driving the actuator results in movement of the piston closely up to the upper portion of the housing to completely discharge paste.
By means of an auxiliary container of variable volume installed inside of the housing, it is possible to discharge a desired amount of more than one sort of paste simultaneously.
It is also possible to contain more than one sort of paste by providing a separating member inside of the housing. The piston or the piston member is formed correspondingly to the chambers formed by the separating member, so that the paste discharging container may be of various shapes depending on the application thereof.
Also, the paste discharging container according to the invention can discharge a specified amount of paste therefrom by driving the actuator with scale marks on the outer surface thereof.
Also, it is possible to discharge a specified amount of paste by forming scale marks on the outer surface of the housing and constructing the actuator.
Also, the lower cap can be configured to be removable from the actuator to keep small articles that may be lost easily in the actuator. Also, by providing a removable external cap on the outer surface of the actuator, it is possible to design a paste discharging container of a refined and simple appearance so that the actuator may not be exposed outside.
Also, since a support member is installed in the housing, the auxiliary container and the separating member can be securely installed and supported within the housing.
Also, by constructing the outlet of the auxiliary container of the paste discharging container to be receded from that of the housing, even when paste with a strong odor is contained in the auxiliary container, the paste contained in the housing covers the paste with the strong odor contained in the auxiliary container, so that the odor cannot spread outside before the paste is discharged.
Also, since the outlets of the housing and the auxiliary container of the paste discharging container according to the invention are separated, the two sorts of paste in the housing and the auxiliary container are not mixed before being discharged. Also, since a plurality of auxiliary containers can be formed in the paste discharging container according to the invention, a plurality of sorts of paste can be contained depending on the application thereof.
Also, it is possible to prevent foreign matters from entering the gaps formed between the housing and the top of the actuator by providing a tightly coupling means between the housing and the actuator to seal the gaps, which is also preferable in terms of fine appearance.
Since a piston mating portion or a mating portion is formed on the piston or the piston assembly, the piston or the piston assembly for engagement with the actuator is structurally stable to be combined with the actuator for operation.
Since the actuator mating portion extends into the connecting member, a paste discharging container is provided which is structurally more stable, and is easy to manufacture and operate.
A paste discharging container comprising a housing, a piston or piston assembly, an actuator and an upper cap can be easily manufactured particularly with a simple configuration, and thus requires a low manufacturing cost. A paste discharging container according to the invention has a first indicating line on the outer surface of the housing, and second indicating lines spaced apart on the outer surface of the tightly coupling member, so that a very small amount of paste corresponding to no more than one pitch of the housing can be discharged.
The present invention has been described in detail. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description. In the claims, use of the verb "comprise" and its conjugations does not exclude the presence of elements or steps other than those stated in a claim. The article "a" or "an" does not exclude the presence of a plurality of the components.
