Title: Portable beverage container including portion pack and fixing cap

Description:
TECHNICAL FIELD 
     The present invention relates to a portion pack storing coffee, herbal tea, or the like that can be drunk by diluting it with water. 
     BACKGROUND ART 
     Recently, a portion pack, which stores coffee, herbal tea, or the like that can be drunk by diluting it with water according to consumer&#39;s preference, is known in the art. Usually, the portion pack is configured to store a liquid concentrate and allow a drinker to drink by diluting it with water stored in a separate container. 
     Meanwhile, there is an inconvenience in the portion pack since the liquid concentrate stored therein should be poured in a separate container then diluted with water. For this reason, the drinker should provide a separate container for diluting the concentrate stored in the portion pack, and the concentrate may flow out to contaminate the surroundings, which causes inconvenience in use. 
     In addition, even though there is a proper amount of water for drinking the concentrate stored in a disposable portion pack, it is always difficult for the drinker to adjust the proper amount of water. In particular, herbs or medicinal plants containing medicinal ingredients are being spotlighted as caffeine-free health ingredients. In order to safely drink these herbs or medicinal plants and obtain their efficacy, it is necessary for the drinker to accurately add the proper amount of water.

     MODE FOR CARRYING OUT INVENTION 
     The present invention may be altered in various ways and have various embodiments, and will be described with reference to the drawings for illustrating specific embodiments. However, the present invention is not limited to the specific embodiments, and it will be understood by those skilled in the art that the present invention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present invention. Further, in description of preferred embodiments of the present invention, the publicly known functions and configurations that are judged to be able to make the purport of the present invention unnecessarily obscure will not be described in detail. 
     First, as illustrated in  FIG. 1 , the portable beverage container according to the present invention may include a portion pack  100  and a fixing cap  300 . 
     Herein, the portion pack  100  may include a fastening part  10  and a storage part  20 . 
     The fastening part  10  is formed in a tubular shape with a circular cross section, and has a first screw  11  formed on an outer circumferential surface thereof to be fastened to a bottled water container  200  through a fixing cap  300  which will be described below. In addition, the storage part  20  forms a space in which a tea bag or a concentrate can be stored. 
     The storage part  20  is formed to have a larger diameter than a diameter of the fastening part  10 , and preferably has a shape which extends from the fastening part  10  with an increased diameter toward a bottom thereof. In particular, the portion pack  100  may be manufactured by a blow molding method for mass production. The blow molding method refers to a method including preforming a raw material in a tube shape by extrusion or injection, then inserting the same into a mold and blowing air into the mold to be billowed, followed by cooling and solidifying the same to prepare a solid product having a specific form. The portion pack  100  according to the present invention may be manufactured by preparing the solid product in the blow molding method as described above, then forming the first screw  11  on the outer circumferential surface of the fastening part  10 . When manufacturing the portion pack  100  by the blow molding method as described above, a production speed and production costs of the product may be reduced. On the other hand, when using a typical injection molding method, since a screw should be formed on an inner surface of the portion pack  100 , the production speed of the product is reduced and the production costs are significantly increased. 
     Meanwhile, as illustrated in  FIGS. 1 and 2 , the fixing cap  300  according to the present invention includes: an inner insertion part  310  disposed by inserting into the fastening part  10  of the portion pack  100  and having a second screw  311  formed on an inner circumferential surface thereof to be screwed with a screw  201  formed at an inlet of the bottled water container  200 ; and an outer insertion part  320  extending from an upper end of the inner insertion part  310  parallel thereto and having a third screw  321  formed on an inner circumferential surface thereof to be screwed with the first screw  11  formed on the fastening part  10  of the portion pack  100 . Herein, the inner insertion part  310  is formed in a tubular shape with a circular cross section having an inner diameter of a dimension enough to be fitted to an outer diameter of the inlet of the bottled water container  200 . The outer insertion part  320  extending from the upper end of the inner insertion part  310  parallel thereto is formed so that the inner insertion part  310  is disposed therein, and is formed in a tubular shape with a circular cross section having an inner diameter of a dimension enough to be fitted to an outer diameter of the fastening part  10  of the portion pack  100 . 
     When using the portable beverage container according to the invention, as illustrated in  FIG. 1 , first, the first screw  11  formed on the fastening part  10  of the portion pack  100  is screwed with the third screw  321  formed on the outer insertion part  320  of the fixing cap  300 . At this time, the outer insertion part  320  and the inner insertion part  310  are configured so that a region of the outer insertion part  320  having the third screw  321  formed thereon and a region of the inner insertion part  310  having the second screw  311  formed thereon are disposed to be overlapped with each other on a plane orthogonal to a vertical line V passing through a center of the inner insertion part  310  and the outer insertion part  320  (i.e., as viewed from a side). In particular, the fastening part  10  of the portion pack  100  is inserted between the outer insertion part  320  and the inner insertion part  310  to be firmly fixed by screwing of the first screw  11  with the third screw  321 . 
     Thereafter, the second screw  311  provided at the inner insertion part  310  of the fixing cap  300  is screwed with the screw  201  provided at the inlet of the bottled water container  200 . At this time, a sleeve  340  formed in the fixing cap is inserted into the inlet of the bottled water container  200  to be firmly fixed. The sleeve  340  may be formed to be spaced apart from the inner circumferential surface of the inner insertion part having the second screw  311  formed thereon with a gap corresponding to a thickness of the inlet of the bottled water container. By the sleeve  340 , the fixing cap  300  and the bottled water container  200  may be more firmly fastened with each other. In addition, since the sleeve  340  is inserted and disposed in the inlet of the bottled water container  200 , when placing the portion pack  100  and the bottled water container  200  which are fastened to each other through the fixing cap  300  by turning upside down as illustrated in  FIG. 1 , bottled water (not illustrated) contained in the bottled water container  200  is guided so as to inflow into the storage part  20  through the fastening part  10 . 
     Meanwhile, since the screw  201  formed on the outer circumferential surface of the inlet of the general bottled water container  200  is formed as a right-handed male screw, the second screw  311  formed on the inner circumferential surface of the inner insertion part  310  is preferably formed as a right-handed female screw that can be screwed with the screw  201 . In addition, the first screw  11  formed on the outer circumferential surface of the fastening part  10  of the portion pack  100  may also be formed as a right-handed male screw, and the third screw  321  formed on the inner circumferential surface of the outer insertion part  320  may be formed as a right-handed female screw that can be screwed with the first screw  11 . When forming both the second screw  311  and the third screw  321  as the right-handed screws, the outer insertion part  320  of the fixing cap  300  is first fastened to the portion pack  100 , and then the inner insertion part  310  of the fixing cap  300  is inserted into the inlet of the bottled water container  200  again, thereby the fastening processes may be performed smoothly. 
     As illustrated in  FIG. 1 , in a state in which the portion pack  100 , the fixing cap  300  and the bottled water container  200  are fastened, when turning upside down so that the portion pack  100  is placed on a downside, the bottled water stored in the bottled water container  200  inflows into the storage part  20  through the fastening part  10 . Thereby, the tea bag or the concentrate stored inside the storage part  20  is diluted with water. When using the portable beverage container in this manner, a drinker maintains the state as illustrated in  FIG. 1  for a considerably long time so that the tea bag or the concentrated is sufficiently diluted with water. In this case, a bottom surface  30  of the portion pack  100  may be formed to have a sufficient diameter so that a state, in which the bottled water container  200  is placed upside down, is safely maintained. In addition, since the storage part  20  has a diameter D 2  which is formed larger than a diameter D 1  of the fastening part  10 , a larger amount of liquid is present on the storage part  20  side than the fastening part  10  side, such that a center of gravity is on the storage part  20  side. Therefore, the state in which the bottled water container  200  is placed upside down may be safely maintained. At this time, the storage part  20  may be manufactured in a shape in which the diameter D 2  thereof is gradually increased toward a bottom section  30  from the fastening part  10 . In this case, a section between the fastening part and the storage part  20  in a vertical direction is formed to be inclined, such that flowability of the concentrate flowing to the bottled water container  200  side may be improved. 
     In addition, when using the fixing cap  300  according to the present invention, the state, in which the bottled water container  200  is placed upside down, may be more stably maintained. That is, since the outer insertion part  320  fastened to the portion pack  100  and the inner insertion part  310  fastened to the bottled water container  200  are disposed to be overlapped with each other on the plane orthogonal to the vertical line V, the center of gravity of the entire container is lowered. 
     In addition, when placing the portion pack  100  fastened to the bottled water container  200  by turning upside down (i.e., when placing so that the portion pack  100  is disposed below), in order to maintain the placed state of the entire container in balance, it is preferable that the portion pack  100  is formed symmetrically about at least one plane including the vertical line V. 
     Meanwhile, the fixing cap  300  according to the present invention may further include a filter part  330  disposed at a lower end of the inner insertion part  310 . The filter part  330  prevents the tea bag or a solid material of the concentrate stored in the portion pack  100  from being introduced into the bottled water container  200 , and also prevents foreign matters stored in the bottled water container  200  from being introduced into the portion pack  100 . 
     However, it is preferable that the liquid bottled water, the concentrate, or a diluent may inflow into an opposite side via the filter part  330 . 
     In addition, it is preferable that the portion pack  100  has a recess  31  formed in the bottom section  30  thereof so that different portion packs may be stacked on each other. In this case, the recess  31  may be formed to have an inner diameter substantially matching with an outer diameter of the upper end of the fastening part of another portion pack or an outer diameter of the outer insertion part  320  of the fixing cap  300 . When using the recess  31 , a plurality of portion packs having the fixing cap  300  fastened thereto or without the fixing cap fastened thereto may be stacked and stored. 
     Using the above-described portable beverage container has the following advantages. 
     First, since the portion pack may be manufactured by selecting a volume of the storage part depending on various herbs and herbal ingredients, the drinker may use by pouring water into the portion pack  100  according to the present invention based on the selected volume, thereby easily adjusting the proper amount of water. 
     Second, since the portable beverage container according to the present invention may be used by fastening with a disposable bottled water container which is readily available in the market, the drinker may use the beverage container according to the present invention while carrying only the same without a need to provide a separate container. 
     Third, the portable beverage container according to the present invention may be used as a stopper by fastening with the bottled water, and may also be used as a cup for drinking a portion of the beverage. In particular, when placing the portable beverage container with being fastened to the bottled water container  200  by turning upside down, by designing the container to sufficiently support a weight of the bottled water container, and designing the center of gravity of the entire container disposed upside down to be lowered, it is possible to more safely use the container. 
     Fourth, since the portion pack forming the portable beverage container according to the present invention is designed to be manufactured by using blow molding not the typical injection or extrusion, a production process of the product is simpler and the manufacturing costs thereof may be further reduced. 
     Next, a portion pack forming a portable beverage container according to another embodiment of the present invention and a fixing cap used therein will be described with reference to  FIGS. 3 to 5 . 
     As illustrated in  FIG. 5 , the portable beverage container according to another embodiment of the present invention may include a portion pack  100  provided with a fastening part  10  and a storage part  20 , a fixing cap  300  configured to be used by fastening with the bottled water container, and a cover  400  configured to seal an upper portion of the fixing cap  300 . 
     Herein, as illustrated in  FIG. 3 , the cover  400  may be latched to a latching part  320   b  which laterally protrudes from the upper end  320   a  of the outer insertion part  320 . 
     Meanwhile, since the container is distributed in a state in which the herb, tea bag, concentrate, or the like is stored in the storage part  20 , it is preferable to finish the upper end of the fixing cap  300  with a separate sealing material  350  so as to prevent the contents contained in the storage part  20  from leaking. At this time, the sealing material  350  or the fixing cap  300  may be peeled off while contracting and expanding according to changes in the temperature during the manufacturing process or distribution. As a result, the contents contained in the storage part  20  may leak. In order to prevent this phenomenon, it is preferable to form a space in the upper portion of the fixing cap  300  at a portion thereof in which the sealing material  350  is adhered. 
     Specifically, in order to prevent the sealing of the sealing material  350  from being released, the sealing material  350  is doubly adhered to the upper end  310   a  of the inner insertion part and the upper end  320   a  of the outer insertion part, respectively. 
     The upper end  310   a  of the inner insertion part and the upper end  320   a  of the outer insertion part are formed at the same height so that the sealing material  350  is uniformly adhered. A groove G is formed between the upper end  310   a  of the inner insertion part and the upper end  320   a  of the outer insertion part. The groove G may be formed in a circular band shape along the circumference of an upper surface of the fixing cap  300 . When forming the groove G as described above, it is possible to effectively prevent the sealing of the sealing material  350  from being released by the contraction or expansion thereof according to the changes in the temperature. 
     In addition, when using the beverage container according to the present invention, in order to allow the liquid to flow between the bottled water container  200  and the portion pack  100 , a plurality of through holes  331  are provided in the filter part  330  formed at the lower surface of the inner insertion part  310 . At this time, when fastening the bottled water container  200  to the fixing cap  300 , an inner space formed by connecting the portion pack  100  and the bottled water container  200  with each other is sealed. In this state, in order to allow the liquid to smoothly flow toward the portion pack  100  or the bottled water container  200 , the through hole  331  needs to have a diameter of 2 mm or more. In addition, in order to maximize a flow rate of the liquid, it is preferable to form the maximum number of the through holes  331  in a given area. That is, as illustrated in  FIG. 4 , it is preferable to arrange the plurality of through holes  331  in a hexagonal dense structure. In particular, if the plurality of through holes  331  are arranged in the hexagonal dense structure, when a user drinks the beverage in the portion pack  100 , the liquid may uniformly flow in all directions. 
     Meanwhile, the herb may be stored in the storage part  20  such that the through hole  331  formed in the filter part  330  may be blocked by the herb to inhibit the flow of the liquid. In order to prevent this phenomenon, arc-shaped stepped portions  332  may be provided on circumferences of the through holes  331 . 
     Preferably, the stepped portion  332  provided on the circumference of the through hole  331  is formed to have an arc length of about 180 degrees or less, and protrudes outward from the lower surface of the inner insertion part  310  by a predetermined height. When forming the stepped portion  332  as described above, a gap may be maintained due to the height of the stepped portion  332  even if the herb is stuck around the through hole  331 , and thereby preventing the through hole  331  from being completely blocked. In particular, it is more effective that the stepped portions  332  respectively formed around the plurality of neighboring through holes  331  are alternately arranged so that respective directions of centers of curvature thereof are different from each other. That is, as illustrated in  FIG. 4 , by arranging the stepped portions  332  so as to be deviated from each other, it is possible to prevent the through holes  331  from being completely blocked even if the herb is stuck between the neighboring through holes  331 . 
     While the present invention has been described with reference to the preferred embodiments, it will be understood by the person who has a common knowledge in the technical field to which the invention pertains that various modifications and variations may be made therein without departing from the scope of the present invention as defined by the appended claims. Accordingly, the embodiments described in this disclosure should not be construed to limit the technical spirit of the present invention, but should be construed to illustrate the technical spirit of the present invention. The scope of the present invention should be interpreted according to the following appended claims not the above description, and the present invention should be construed to cover all modifications or variations induced from the meaning and scope of the appended claims and their equivalents.
