The cover part  22  is provided with a perforation line  24 , a tab  25 , and the like, as appropriate. A user lifts the cover part  22  in a direction in which the cover part  22  is opened with respect to the body part  21  by, for example, holding the tab  25  and opens the outer package  2  by cutting the cover part  22  along the perforation line  24 . 
       FIG. 2  is a top view of the body part  21  after the outer package  2  according to Embodiment 1 is opened. An inner pack  5  that houses an oral tobacco material  3  and a gum molded body  4  is disposed in an internal space of the outer package  2 .  FIG. 3  is a view schematically illustrating a section in the direction of arrows A-A in  FIG. 2 . The reference sign  26  in  FIG. 3  indicates a housing portion formed in an inner portion of the body part  21 . The inner pack  5  illustrated in  FIG. 2  and  FIG. 3  is housed in the housing portion  26  of the body part  21 . 
     The inner pack  5  has a shape of a tray and includes a tobacco housing portion  51  as a recessed portion for housing the oral tobacco material  3 , and a gum housing portion  52  as a recessed portion for housing the gum molded body  4 . In the present embodiment, the inner pack  5  is provided with a plurality of the tobacco housing portions  51  and a plurality of the gum housing portions  52 . Consequently, in the inner pack  5 , the oral tobacco material  3  and the gum molded body  4  are housed in a state of being separated. In the example illustrated in  FIG. 2 , ten tobacco housing portions  51  are provided in a first region R 1  of the inner pack  5 , and the oral tobacco material  3  is housed in each of the tobacco housing portions  51 . In addition, ten gum housing portions  52  are provided in a second region R 2  of the inner pack  5 , and the gum molded body  4  is housed in each of the gum housing portions  52 . Note that the numbers of the tobacco housing portions  51  and the gum housing portions  52  that are provided in the inner pack  5  are not particularly limited. The numbers of the tobacco housing portions  51  and the gum housing portions  52  that are provided in the inner pack  5  may differ from each other. The reference sign  53  in  FIG. 3  indicates a hermetic seal that seals the tobacco housing portions  51  and the gum housing portions  52  in the inner pack  5 . The hermetic seal  53  in the inner pack  5  is not essential. However, from the point of view of flavor retainability of the oral tobacco material  3  and the gum molded body  4 , it is preferable that the oral tobacco material  3  and the gum molded body  4  be air-tightly packed. The oral tobacco material  3  and the gum molded body  4  may be packed individually (for example, in a pillow shape). 
       FIG. 4  is a view illustrating the oral tobacco material  3  and the gum molded body  4  according to Embodiment 1. The oral tobacco material  3  contains a tobacco raw material from which a tobacco component is eluted when being chewed by a user.

One of these flavors may be used alone, or two or more of these flavors may be used in combination. 
     The method of manufacturing the oral tobacco material  3  is not particularly limited. The oral tobacco material  3  may be formed by an appropriate manufacturing method such as extrusion molding, granulation, tablet molding, spray drying, or the like in accordance with the shape thereof. 
     The fragility of the oral tobacco material  3  is preferably in a range of 5 to 100 N and more preferably in a range of 10 to 50 N. 
       FIG. 5  is a view describing a measurement unit  100  that measures fragility of the oral tobacco material  3 . A front view of the measurement unit  100  is schematically illustrated on the left side, and a side view of the measurement unit is schematically illustrated at the center. As the measurement unit  100 , a general compression tester (for example, a compression tester (EZ-tester) manufactured by Shimadzu Corporation, or the like) is usable. The measurement unit  100  includes a flat table  101  on which a fragility measurement object (oral tobacco material  3 ) is to be placed, a loading unit  102 , and the like. The loading unit  102  includes an ascending-descending rod  104  having a tip to which an indenter  103  (line contact body) is attached, a load cell (not illustrated), and the like and supports the ascending-descending rod  104  to be able to ascending and descending in a direction orthogonal to the table  101 . A sectional view of the indenter  103  of the loading unit  102  is schematically illustrated on the right side in  FIG. 5 . The indenter  103  is made of SUS304. The indenter  103  has a substantially triangular section in which each side is 10 mm. A force application portion  103 A at the lower end thereof that applies a force to a fragility measurement object (oral tobacco material  3 ) has a corner R (radius) of 0.5 mm and a length of 30 mm. In fragility measurement of the oral tobacco material  3 , a fragility measurement object (oral tobacco material  3 ) is placed at a predetermined position on the table  101 , thereafter, the ascending-descending rod  104  of the loading unit  102  is lowered at a predetermined speed, and a load is applied to the fragility measurement object (oral tobacco material  3 ) placed between the table  101  and the force application portion  103 A of the indenter  103 . In the measurement, a speed at which the loading unit  102  lowers the ascending-descending rod  104  is set to 10 ram/min. The load applied to the fragility measurement object (oral tobacco material  3 ) during the load application is measured by the road cell. The value of the applied load at the time when the fragility measurement object (oral tobacco material  3 ) is broken can be considered as fragility (strength) of the fragility measurement object (oral tobacco material  3 ). 
     Next, the gum molded body  4  will be described. The gum molded body  4  contains a gum base, a humectant, sugar, flavor, and the like. In the example illustrated in  FIG. 4 , the gum molded body  4  is molded in a solid tablet shape. As described above, the gum molded body  4  does not contain a tobacco raw material. As the gum base of the gum molded body  4 , a general gum base used in chewing gum is applicable. In one example, the content of the gum base in the gum molded body  4  is, for example, within a range of 25 wt % to 60 wt %. The gum molded body  4  according to the present embodiment is constituted by, for example, polyhydric alcohol as a humectant. The polyhydric alcohol can include glycerin, propylene glycol, sorbitol, xylitol, and erythritol. These polyhydric alcohols are usable alone or in combination of two or more of them. The gum molded body  4  may contain, as sugar, powdered sorbitol, a sorbitol aqueous solution, or the like. The gum molded body  4  may contain, as flavor, menthol or the like. The gum molded body  4  may contain, as appropriate, the aforementioned flavors presented as examples of the flavor contained in the oral tobacco material  3 . The gum molded body  4  may contain components other than those described above and may not contain some components such as sugar, flavor, and the like. 
     In the present embodiment, the gum molded body  4  includes a hollow or recessed tobacco reception portion  40  for receiving the oral tobacco material  3 . In the example illustrated in  FIG. 4 , the tobacco reception portion  40  of the gum molded body  4  is formed as a cavity portion formed as a recessed portion that opens on a surface of the gum molded body  4 .  FIG. 6  is a view illustrating a sectional shape of the gum molded body  4  according to Embodiment 1, including the tobacco reception portion  40 . The capacity (capacity of the cavity portion) of the tobacco reception portion  40  of the gum molded body  4  is larger than the oral tobacco material  3 , and the oral tobacco material  3  can be inserted into the inner portion of the tobacco reception portion  40 . The tobacco reception portion  40  is not required to be hollow or recessed. 
     In the oral tobacco product  1  configured as described above, after the hermetic seal  53  of the inner pack  5  is opened by a user, typically, one each of the oral tobacco material  3  housed in the tobacco housing portion  51  and the gum molded body  4  housed in the gum housing portion  52  are taken out. After inserting and housing, as illustrated in  FIG. 7 , the oral tobacco material  3  in the tobacco reception portion  40  of the gum molded body  4 , the user holds in the oral cavity the oral tobacco material  3  and the gum molded body  4  that are integrated with each other (hereinafter, the oral tobacco material  3  and the gum molded body  4  that are thus integrated with each other are referred to as “tobacco gum  7 ”) and chews the tobacco gum  7 . Consequently, the user can take a tobacco component eluted from the oral tobacco material  3 . Since the user chews the tobacco gum  7  in a state in which the oral tobacco material  3  and the gum molded body  4  are combined together, the user can obtain an appropriate chewiness imparted by the gum base of the gum molded body  4  and can taste sweetness imparted by sugar of the gum molded body  4 , flavor imparted by menthol, and the like, together with the tobacco component. 
     In the oral tobacco product  1  according to the present embodiment, the inner pack  5  houses the oral tobacco material  3  and the gum molded body  4  in a separated state. In other words, differently from existing oral tobacco compositions, the oral tobacco material  3  and the gum molded body  4  are not integrally molded. Accordingly, a user can combine the oral tobacco material  3  and the gum molded body  4  in accordance with feelings and likings at each time, as in the aforementioned example, and chew the oral tobacco material  3  and the gum molded body  4  together. In addition, the user can chew only the gum molded body  4  containing no tobacco raw material to enjoy the flavor thereof. Moreover, in the oral tobacco product  1  according to the present embodiment, the amount (the number) of the oral tobacco materials  3  that are to be chewed together with one gum molded body  4  can be changed in accordance with feelings and likings when the tobacco gum  7  is to be tasted. For example, it is possible to throw one gum molded body  4  and a plurality of oral tobacco materials  3  into the oral cavity or throw a plurality of divided pieces of one oral tobacco material  3  together with the gum molded body  4  into the oral cavity and possible to taste the tobacco gum  7  by adjusting the amount of a flavor component eluted as a result of these being chewed together in accordance with preferences of a user. The tobacco reception portion  40  of the gum molded body  4  may be formed as a cavity portion having a size with which a plurality of the oral tobacco materials  3  can be housed. As described above, the oral tobacco product  1  according to the present embodiment enables the amount of the oral tobacco material  3  relative to one gum molded body  4  to be changed freely in accordance with feelings and likings and thus is easily enjoyed in accordance with preferences of a user. Therefore, it is possible to provide the oral tobacco product  1  that is highly satisfactory for a user. 
     In addition, in the oral tobacco product  1  according to the present embodiment, the gum molded body  4  includes the tobacco reception portion  40  for receiving the oral tobacco material  3 . Therefore, a user can easily complete the tobacco gum  7  in which the oral tobacco material  3  and the gum molded body  4  are integrally combined by housing the oral tobacco material  3  in the tobacco reception portion  40  of the gum molded body  4  by the hands. Consequently, the user can easily throw the tobacco gum  7  into the oral cavity. As a result of the oral tobacco material  3  being housed in the tobacco reception portion  40  of the gum molded body  4 , it is possible to maintain the integrity of them even during chewing. Therefore, the gum molded body  4  and the oral tobacco material  3  are not easily separated from each other in the oral cavity when the tobacco gum  7  is chewed. 
     In addition, a user can reduce a chance of only the oral tobacco material  3  coming into direct contact with the inside of the oral cavity by chewing the tobacco gum  7  with the oral tobacco material  3  housed in the tobacco reception portion  40  of the gum molded body  4 . Consequently, the texture (mouthfeel) of the tobacco gum  7  is improved, and the eluting speed of a tobacco component contained in a tobacco raw material of the oral tobacco material  3  is easily controlled appropriately. 
     The oral tobacco product  1  according to the present embodiment can employ various modifications. For example, the first region R 1  in which the tobacco housing portion  51  is disposed and the second region R 2  in which the gum housing portion  52  is disposed are provided integrally in the inner pack  5  according to the present embodiment. The inner pack  5  is, however, not limited thereto. That is, the inner pack  5  may be housed in the housing portion  26  of the outer package  2  (body part  21 ) in a form in which the first region R 1  and the second region R 2  are separated. In addition, although a form in which the tray-shaped inner pack  5  is disposed in an inner portion of the outer package  2  has been described as an example in the present embodiment, the form is not limited thereto. For example, one or a plurality of blister packs may be arranged instead of the inner pack  5 , and the oral tobacco material  3  and/or the gum molded body  4  may be housed in the blister packs. In this case, the tobacco housing portion  51  and/or the gum housing portion  52  is formed in the blister pack. Alternatively, without providing the inner pack  5 , blister packs, and the like in the housing portion  26  of the outer package  2  (body part  21 ), the oral tobacco material  3  and the gum molded body  4  may be housed in a separated form directly in the housing portion  26 . For example, each of the oral tobacco material  3  and the gum molded body  4  may be individually packed by a packaging material, a plurality of the oral tobacco materials  3  may be packed into one by a packaging material, or a plurality of the gum molded bodies  4  may be packed into one by a packaging material. Then, the oral tobacco materials  3  and the gum molded bodies  4  in such a state may be housed in the housing portion  26  of the outer package  2  (body part  21 ). 
     In the oral tobacco product  1  according to the present embodiment, the oral tobacco materials  3  of different types of tastes, flavors, and the like may be housed in the tobacco housing portions  51  in the first region R 1  of the inner pack  5 . For example, in the first region R 1  of the inner pack  5 , the oral tobacco materials  3  of a plurality of different types of tobacco raw materials and flavors may be housed in the tobacco housing portions  51 . In the second region R 2  of the inner pack  5 , the gum molded bodies  4  of different types of tastes, flavors, and the like may be housed in the gum housing portions  52 . For example, in the second region R 2  of the inner pack  5 , the gum molded bodies  4  of a plurality of different types of sugars and flavors may be housed in the gum housing portions  52 . Consequently, a user can taste and enjoy the tobacco gum  7  by changing the combination of the gum molded body  4  and the oral tobacco material  3  in accordance with feelings and preferences. Accordingly, it is possible to provide the oral tobacco product  1  capable of more flexibly responding to feelings and preferences of a user. Needless to say, in the aforementioned modifications, the types and the number of the oral tobacco materials  3  housed in the first region R 1  of the inner pack  5  and the types and the number of the gum molded bodies  4  housed in the second region R 2  are not particularly limited. 
     The shapes, the sizes, the number, the forms, and the like of the oral tobacco materials  3  housed in the tobacco housing portions  51  of the inner pack  5  are also not particularly limited. For example, the oral tobacco material  3  may be in a form other than a tablet form, such as a rod, string, plate, cylinder, or hollow form, or a form of a combination thereof. The oral tobacco material  3  may be in a granular form or a powder form. The form of the oral tobacco material  3  is not limited to a solid body (solid form) and may be gelatinous (gel form) or liquid. The forms such as the shapes, the sizes, the number, and the like of the tobacco housing portions  51  of the inner pack  5  can be changed, as appropriate, in accordance with the forms of the oral tobacco material  3  to be housed. 
     The shapes, the sizes, the number, the forms, and the like of the gum molded bodies  4  that are to be housed in the gum housing portions  52  of the inner pack  5  are not particularly limited. For example, the gum molded body  4  may not necessarily provided with the tobacco reception portion  40 . In this case, a user places the oral tobacco material  3  taken out from the tobacco housing portions  51  on the gum molded body  4  taken out from the gum housing portions  52  and throws them together into the oral cavity. The gum molded body  4  may have, on a surface thereof, a recessed depression for receiving the gum molded body  4 . Consequently, a user can place the oral tobacco material  3  on the gum molded body  4  more easily. The gum molded body  4  may have a cylindrical shape, a sheet shape, or a hotdog shape.  FIG. 8  is a view describing a gum molded body  4 A and an oral tobacco material  3 A according to Modification 1.

Consequently, a user can hold the gum molded body  4 D and the oral tobacco material  3 D in a combined state in the oral cavity. 
     Embodiment 2 
     Next, Embodiment 2 will be described.  FIG. 12  is a top view of an inner pack  5 A according to Embodiment 2. The inner pack  5 A according to Embodiment 2 differs from that in Embodiment 1 in terms of the form of a tobacco housing portion provided in the first region R 1  and the form of an oral tobacco material housed in the tobacco housing portion. Hereinafter, differences from Embodiment 1 will be described mainly. Regarding the present embodiment, the same components as those in Embodiment 1 are given the same reference signs, and detailed description thereof is omitted. 
     Two tobacco housing portions  51 A are provided in the first region R 1  of the inner pack  5 A illustrated in  FIG. 12 . A plate-shaped oral tobacco material  3 E is housed in each of the tobacco housing portions  51 A. The tobacco housing portions  51 A each have an elongated flat shape to be able to house the plate-shaped oral tobacco material  3 D.  FIG. 13  is a view illustrating the oral tobacco material  3 E according to Embodiment 2. The oral tobacco material  3 E has a long flat plate shape and includes thin portions  30 A to  30 D that are provided at regular intervals in a long-side direction. The thin portions  30 A to  30 D are portions where the thickness of the oral tobacco material  3 E is thin compared with the other portions. Each of the thin portions  30 A to  30 D extends from one edge portion to the other edge portion in a short-side direction of the oral tobacco material  3 E. The thus formed oral tobacco material  3 E is configured to be easily cut along the thin portions  30 A to  30 D so that the oral tobacco material  3 E can be divided into small tobacco fragments. 
     In the example illustrated in  FIG. 13 , the thin portions  30 A to  30 D are provided at equal intervals at four locations in the oral tobacco material  3 E and are configured such that the oral tobacco material  3 E can be equally divided into five by a user. However, the forms such as the number of the thin portions  30 A to  30 D, and the like in the oral tobacco material  3 E are not particularly limited. The thin portions  30 A to  30 D in the oral tobacco material  3 E are not essential. The thin portions  30 A to  30 D may not be provided. 
     As described above, the plate-shaped oral tobacco material  3 E is housed in each of the tobacco housing portions  51 A in the first region R 1  of the inner pack  5 A according to Embodiment 2. The form of the second region R 2  of the inner pack  5 A is the same as that in Embodiment 1. Ten gum molded bodies  4  in total are individually housed in the gum housing portions  52 . 
     To chew the tobacco gum, a user takes out the plate-shaped oral tobacco material  3 E from the tobacco housing portion  51 A of the inner pack  5 A and divides the oral tobacco material  3 E along any of the thin portions  30 A to  30 D, as appropriate, to adjust the amount of the oral tobacco material  3 E in accordance with feelings and likings. For example, the plate-shaped oral tobacco material  3 E may be cut along the thin portion  30 A illustrated in  FIG. 13 , and, after a tobacco fragment having a normal size is inserted into the tobacco reception portion  40  of the gum molded body  4  that is taken out from the gum housing portion  52 , a tobacco gum that is constituted by a combination of the oral tobacco material  3 E and the gum molded body  4  may be chewed. Alternatively, a tobacco fragment having a size two times the normal size obtained by cutting the plate-shaped oral tobacco material  3 E along the thin portion  30 B illustrated in  FIG. 13  may be inserted into the tobacco reception portion  40  of the gum molded body  4 , or a tobacco fragment having a size three times the normal size obtained by cutting the plate-shaped oral tobacco material  3 E along the thin portion  30 C may be inserted into the tobacco reception portion  40  of the gum molded body  4 . 
       FIG. 14  illustrates a situation in which a tobacco fragment  31  having a size two times the normal size obtained by cutting the plate-shaped oral tobacco material  3 E along the thin portion  30 B illustrated in  FIG. 13  is to be inserted into the tobacco reception portion  40  of the gum molded body  4 . In the gum molded body  4  according to the present embodiment, the tobacco reception portion  40  has a size with which the tobacco fragment  31  having a size several times the normal size can be housed. In the example illustrated in  FIG. 14 , a situation in which the tobacco fragment  31  is to be inserted into the tobacco reception portion  40  of the gum molded body  4  with the tobacco fragment  31  folded along a boundary at the thin portion  30 B is illustrated. As described above, in the oral tobacco product  1  according to the present embodiment, the amount of the oral tobacco material  3 E to be combined with one gum molded body  4  can be adjusted freely by a user. It is thus possible to provide the oral tobacco product  1  that is highly freely enjoyable and highly satisfactory for a user. The tobacco housing portion  51 A in the first region R 1  of the inner pack  5 A illustrated in  FIG. 12  may be covered by a re-peelable hermetic seal with week adhesive paste or the like to be able to store the plate-shaped oral tobacco material  3 E repeatedly in an airtight state. The tobacco housing portion  51 A may be covered by a cover with a zipper, or the like so that opening and hermetically sealing of the tobacco housing portion  51 A are switchable. According to these, the airtightness of the tobacco housing portion  51 A can be ensured repeatedly. 
     In the present embodiment, the plate-shaped oral tobacco materials  3 E housed in the tobacco housing portions  51 A of the inner pack  5 A may contain tobacco raw materials of different types of flavors and thereby differ from each other in terms of the types of tastes, flavors, and the like. Similarly, the gum molded bodies  4  of a plurality of different types of tastes, flavors, and the like may be housed in the second region R 2  of the inner pack  5 A. Consequently, as described in a modification of Embodiment 1, a user can enjoy a tobacco gum by freely changing the combination of the gum molded body  4  and the oral tobacco material  3 E in accordance with feelings and preferences. 
     Embodiment 3 
     Next, Embodiment 3 will be described.  FIG. 15  is a top view of an inner pack  5 B according to Embodiment 3. The inner pack  5 B according to Embodiment 3 differs from that in Embodiment 1 in terms of the form of a tobacco housing portion provided in the first region R 1  and the shape of an oral tobacco material housed in the tobacco housing portion. Hereinafter, differences from Embodiments 1 and 2 will be described mainly. Regarding the present embodiment, the same components as those in Embodiments 1 and 2 are given the same reference signs, and detailed description thereof is omitted. 
     As illustrated in  FIG. 15 , a single tobacco housing portion  51 B is provided in the first region R 1  of the inner pack  5 B. The tobacco housing portion  51 B houses a tube container  6 . A plurality of the gum housing portions  52  are provided in the second region R 2  of the inner pack  5 B. Each of the gum housing portions  52  houses the gum molded body  4 D illustrated in  FIG. 11 . The numbers of the gum housing portions  52  and the gum molded bodies  4 D housed in the gum housing portions  52  are not particularly limited. In the example illustrated in  FIG. 15 , ten gum housing portions  52  are provided in the second region R 2  of the inner pack  5 B. 
     The tube container  6  includes a container body  61  and a cover (cap)  62 . A gelatinous (gel form) oral tobacco material is charged in an inner portion of the container body  61  of the tube container  6 . In other words, in the present embodiment, a gelatinous oral tobacco material in a state of being charged in the tube container  6  (container body  61 ) is housed in the tobacco housing portion  51 B in the first region R 1  of the inner pack  5 B. The gelatinous oral tobacco material charged in the tube container  6  can be configured to contain a tobacco raw material, a binder, a humectant, a flavor, and the like. The viscosity of the gelatinous oral tobacco material charged in the tube container  6  is preferably within a range of about 10 Pa to about 150 Pa. The gelatinous oral tobacco material charged in the tube container  6  may contain a gelling agent. As examples of a gelling agent, for example, there are presented pectin, gellan gum, sodium alginate, gum arabic, xanthan gum, tragacanth gum, and the like. When the oral tobacco material contains a gelling agent, the content of the gelling agent is preferably in the range of 0.1 wt % to 10 wt %. 
     As described with reference to  FIG. 11 , a recessed depression is formed as the tobacco reception portion  40  on a surface of the gum molded body  4 D. Consequently, the gelatinous oral tobacco material squeezed from the tube container  6  is received by the recessed tobacco reception portion  40  formed on the gum molded body  4 D, and the gelatinous oral tobacco material can be held on the gum molded body  4 D. 
     For example, a user takes out the tube container  6  and the gum molded body  4 D from the tobacco housing portion  51 B and the gum housing portions  52  of the inner pack  5 B according to the present embodiment, respectively. Then, the user removes the cover  62  from the container body  61  of the tube container  6  and, as illustrated in  FIG. 16 , squeezes a gelatinous oral tobacco material  3 F that is a content of the container body  61  into the tobacco reception portion  40  that is the recessed depression formed on a surface of the gum molded body  4 D. The tobacco gum  7  in a state in which the oral tobacco material  3 F is thus held in the tobacco reception portion  40  of the gum molded body  4 D is thrown into the oral cavity, these are chewed together, and the tobacco gum  7  can be tasted. 
     According to the present embodiment, the amount of the oral tobacco material  3 F to be dispensed (squeezed) from the tube container  6  into the tobacco reception portion  40  of the gum molded body  4 D can be freely changed by a user in accordance with feelings and likings. It is thus possible to provide the oral tobacco product  1  that is highly freely enjoyable and highly satisfactory for a user. Needless to say, gum molded bodies  4  of a plurality of different types of tastes, flavors, and the like may be housed in the gum housing portions  52  in the inner pack  5 B according to the present embodiment. Consequently, a user can freely change the type of the gum molded body  4  to be combined with the oral tobacco material  3 F. In addition, a plurality of tube containers  6  may be disposed in the first region R 1  of the inner pack  5 B. In this case, a plurality of the tube containers  6  may be housed in one tobacco housing portion  51 B, or a plurality of tube containers  6  may be housed individually in the tobacco housing portion  51 B. When a plurality of tube containers  6  are housed in the inner pack  5 B, the type of the tobacco raw material and the type of the flavor in the oral tobacco materials  3 F charged in the inner portion may differ between one tube container  6  and the other tube containers  6 . Consequently, a user can freely change the type of the oral tobacco material  3 F that is to be combined with the gum molded body  4 . 
     Although the gelatinous oral tobacco material  3 F is charged in the tube container  6  in the above-described example, a liquid oral tobacco material may be charged instead in the tube container  6 . The container in which a gelatinous or liquid oral tobacco material is to be charged is not limited to be in a tube form. For example, various containers such as a sauce bottle and a spuit container can be employed. 
     Needless to say, the form of a gum molded body to be combined with a gelatinous or liquid oral tobacco material is not limited to the form illustrated in  FIG. 11 . However, when a gelatinous or liquid oral tobacco material is used, it is preferable that the gum molded body has the tobacco reception portion  40  for receiving the oral tobacco material. For example, the gum molded body according to the present embodiment may have a cup shape suitable for receiving a gelatinous or liquid oral tobacco material without spilling the oral tobacco material. However, when the viscosity of the gelatinous or liquid oral tobacco material is high to some extent and the oral tobacco material does not spill from the gum molded body in the present embodiment, the gum molded body does not necessarily include the recessed or hollow tobacco reception portion  40 . 
     Embodiments and modifications of the oral tobacco product according to the present invention have been described above. The oral tobacco product according to the present invention is, however, not limited thereto. The embodiments and the modifications described above can be combined, as appropriate.
