Description

  The present invention relates to a viscous material storage container for storing a viscous material having fluidity.

  Conventionally, the container which stores mayonnaise is known as this kind of viscous container (for example, refer patent document 1).

  In the container of patent document 1, since the discharge hole which discharges mayonnaise is formed by the decorative shape, when mayonnaise is squeezed out, for example, mayonnaise is extruded by cross-sectional star shape.

JP-A-9-188340

Such mayonnaise containers may be manufactured by blow molding.
In this case, in the configuration of the prior art described above, there is a problem that the shape of the discharge hole cannot be manufactured by one molding because the thickness of the discharge portion is thin (about 1.5 mm). For this reason, in the conventional manufacturing process, it is necessary to manufacture the main body part of a mayonnaise container by blow molding, and to make a star-shaped hole in the part corresponding to a discharge part after that. If it does so, a work process will increase and a manufacturing cost will become high.

  On the other hand, unlike the prior art described above, there is also a method in which a thin piece having a star-shaped hole is attached as a separate member to the main part of the mayonnaise container. However, in the case of this method, the number of parts increases by the amount of the flakes, which also increases the manufacturing cost.

  Therefore, an object of the present invention is to provide a technique capable of suppressing the manufacturing cost by adopting a shape suitable for molding.

  In order to solve the above problems, the present invention employs the following solution means. In addition, the wording in the parenthesis shown below is an illustration to the last, and this invention is not limited to this.

Solution 1: The viscous material storage container of the present solution includes a container body and a standing wall.
The container body stores a viscous material having fluidity. Examples of viscous products include foods such as mayonnaise and ketchup.

  The standing wall is formed integrally with the container body. The container body and the standing wall can be integrally formed by, for example, blow molding. Further, the standing wall is formed so as to stand upward from the upper portion (upper end portion, above the thread) of the container body. Further, the standing wall forms a mouth portion having a predetermined shape including a straight line at least partially. The contour of a predetermined shape including a straight line at least in part is, for example, a polygonal contour, a star-shaped contour, a semicircular contour, etc., and excludes a perfect circular contour. Further, the predetermined shape including at least a part of a straight line is a shape formed of at least a plurality of surfaces, and a ridge line is formed in a straight line at a boundary between the plurality of surfaces. It is preferable to provide a curved surface.

  Thus, according to this solution, since the container body and the upright wall are integrally formed, the number of parts can be reduced as compared with the configuration in which the flakes having the star-shaped holes are attached later. Manufacturing cost can be reduced.

  Further, according to the present means for solving the problem, the standing wall that forms the mouth portion having a predetermined shape including a straight line at least in part is formed so as to stand upward from the upper part of the container body. The length of the upright wall (mouth) in the direction (top and bottom direction) can be secured long.

  As a result, when the container body and the standing wall are molded integrally, a wide contact area between the side surface of the standing wall and the mold (for example, a split mold used for blow molding) can be secured. A suitable standing wall shape can be used. By adopting such a standing wall shape, the container body and the standing wall forming the mouth can be easily formed integrally, and as a result, the manufacturing cost can be reduced.

Solution 2: The viscous material storage container of the present solution includes a container body and an upright wall.
The container body stores a viscous material having fluidity. The standing wall is formed integrally with the container main body, and is formed to rise upward from the upper part of the container main body. Further, the standing wall has a mouth portion having a predetermined shape including a straight line at least partially, an auxiliary surface extending outwardly from the outer periphery of the mouth portion in a flat plate shape, and having a circular shape, and an auxiliary surface And an auxiliary wall formed in a cylindrical shape rising upward from the outer periphery. That is, the top end portion of the auxiliary wall forms the top end portion of the standing wall, and the outline thereof is formed in a circular shape.

Solution 3: The viscous material storage container of the present solution includes a container body and an upright wall.
The container body stores a viscous material having fluidity. The standing wall is formed integrally with the container body, and rises in a cylindrical shape upward from the upper part of the container body. Further, the standing wall is formed with a narrowed mouth portion at the middle portion viewed in the vertical direction, so that a cylindrical auxiliary wall is formed above the mouth portion, and the upper end of the mouth portion and the lower end of the auxiliary wall are formed. The gap is connected via an auxiliary surface extending in a flat plate shape toward the outer periphery of the mouth. The mouth portion is formed in a predetermined shape in which at least a part of the contour viewed in cross section includes a straight line.

  In the solving means 2 and 3, first, similarly to the solving means 1, the number of parts can be reduced by integrally forming the container main body and the standing wall. Further, since the mouth portion has a predetermined shape contour including a straight line at least in part, a large contact area between the outer surface of the standing wall and the mold at the time of molding can be secured, and the container body and the mouth portion are formed. Integral molding with the standing wall becomes easy. Thus, it is possible to reduce the manufacturing cost.

  In this solution means, in addition to these effects, the outer periphery of the top end portion of the upright wall is formed in a circular shape, so that the cutter can easily enter. At the stage where the container is blow-molded, so-called disposal bags are continuously formed above the standing wall. From the viewpoint of hygiene of the container, the waste bag is cut off from the container by making the cutter enter a portion that hits the top end of the standing wall with the container turned upside down just before filling the viscous material. At this time, since the outer periphery of the part to be cut is formed in a simple shape of a circular shape, the cutter can be smoothly entered. Thereby, it becomes possible to form the top end face of the standing wall more favorably.

  Solution 4: In the present solution, the container body has a cylindrical body part, a bottom surface disposed at a lower part of the body part, and a top surface disposed at an upper part of the body part. For this reason, the viscous material can be supported by the bottom surface, the viscous material can be held by the body portion, and the volume of the body portion can be divided by the top surface. An opening corresponding to the mouth is formed on the top surface. The standing wall is formed so as to rise upward from the top surface.

  As described above, in the present solution, the top surface is disposed on the upper portion of the body portion, and the standing wall is disposed on the top surface. Therefore, the standing wall can be stably disposed by the base called the top surface. In addition, since the standing wall can be stored inside the outer periphery of the top surface, the standing wall does not get in the way when the cap is attached.

  Solution 5: In this solution, a hinge cap is added. The hinge cap has a spout for pouring viscous material and a lid that covers the spout so as to be opened and closed by a hinge mechanism. In addition, the container body has a thread portion (thread, protrusion, etc.) for attaching a hinge cap below the standing wall. And in the state which attached the hinge cap to the container main body using the thread part, at least one part of the top end surface of a standing wall contact | abuts the inner surface of a hinge cap.

  Thus, according to this solution, since at least a part of the top end surface of the standing wall abuts the inner surface of the hinge cap with the hinge cap attached to the container body, A sealed space can be formed, and leakage of the stored viscous material can be avoided.

  Solution 6: In this solution, the hinge cap has an annular protrusion protruding toward the container body. Then, with the hinge cap attached to the container body using the threaded portion, the outer periphery of the top end surface of the standing wall is disposed outside the outer periphery of the lower end surface of the protruding portion, and the inner end of the top end surface of the standing wall is The circumference is arranged inside the inner circumference of the lower end surface of the protrusion.

  In the present solution, since such an arrangement relationship is adopted, the top end surface of the upright wall is within the range of the lower end surface of the protrusion, and the contained viscous material leaks out. Can be avoided.

  Solution 7: In the present solution, the hinge cap has an annular protrusion protruding toward the container body. Then, with the hinge cap attached to the container body using the thread portion, the outer periphery of the top end surface of the standing wall is disposed outside the inner periphery of the lower end surface of the protruding portion, and the top end surface of the standing wall is The inner periphery is arranged inside the outer periphery of the lower end surface of the protrusion.

  In this solution, since such an arrangement relationship is adopted, the lower end surface of the protrusion covers the entire circumference of the mouth formed by the standing wall, and the stored viscous material leaks out. Can be avoided.

  Solution 8: In this solution, the opening area of the spout is smaller than the opening area of the mouth. For this reason, a viscous material can be extrude | pushed out thinly by a spout, or a thick viscous material can be extruded by a mouth part, and it can implement | achieve two types of extrusion aspects.

  Solution 9: In this solution, at least one of the container main body and the upright wall has a connecting portion (parting line) of a resin material as a raw material. The predetermined shape is a star shape having a plurality of protrusions (six corners). And at least 1 protrusion is arrange | positioned in the position which overlaps with a coupling | bond part (up-down direction or a top-bottom direction) among several protrusions. The number of the plurality of protrusions is preferably an even number in consideration of symmetry.

  As described above, in the present solution, at least one of the plurality of protrusions is disposed at a position overlapping with the coupling portion, so that the tip of the projection faces the coupling portion. Thereby, when removing a metal mold | die in a manufacturing process, it can be set as the form which is easy to take out.

  According to the present invention, since the standing wall that forms the mouth is erected upward from the upper part of the container main body, the shape can be made suitable for molding, and the manufacturing cost can be reduced. .

The container body 20 is a resin-made container that stores mayonnaise (viscous material) having fluidity. The container body 20 includes a cylindrical body portion 21, a bottom surface 22 disposed at the lower portion of the body portion 21, and a top surface 23 disposed at the upper portion of the body portion 21. The body portion 21 has a shape in which the width in the vicinity of the center is the largest, the width in the lower portion is slightly narrower than that in the vicinity of the center, and the width gradually decreases from the vicinity of the center toward the upper portion.

  The container body 20 has a screw thread (screw thread portion) 24 for attaching a hinge cap 40 (see FIG. 3) below the top surface 23 (below the standing wall 30).

[Standing wall]
The standing wall 30 is formed integrally with the container body 20 and is formed to rise upward from the top surface 23 of the container body 20. Further, the standing wall 30 forms a mouth portion 31 having a star-shaped contour having six protrusions. The dimensions of the standing wall 30 can be freely set depending on the molding conditions and the cap to be attached. For example, the thickness can be set to about 1.0 to 3.0 mm (wall thickness), and 5.0 The height can be about 15.0 mm. An opening corresponding to the mouth portion 31 is formed in the top surface 23.

  FIG. 2 is a plan view, a front view, and a right side view of the mayonnaise container 10. 2A is a plan view, FIG. 2B is a front view, and FIG. 2C is a right side view.

  Although not specifically shown, after filling the mayonnaise container 10 with mayonnaise, an aluminum seal is affixed to the top end surface 32 of the upright wall 30, and the aluminum seal is peeled off during use. The protrusion 47 is an annular contact ring that functions as a member that presses the aluminum seal before the first use, and functions as a member that contacts the top end surface 32 of the standing wall 30 after the first use.

FIG. 6 is a diagram illustrating a relationship between the shape of the top end surface of the standing wall 30 and the shape of the inner surface of the hinge cap 40.
Various shapes can be adopted as the shape of the standing wall 30 and the shape of the inner surface of the hinge cap 40 depending on the application. For example, any of the following first to fourth examples can be applied. it can.

  Moreover, in the figure, the state which attached the hinge cap 40 to the container main body 20 is shown. Note that the top end surface of the standing wall 30 is indicated by a solid line, and other members (for example, the bottom surface of the projection 47 of the hinge cap 40, etc.) are indicated by dotted lines.

[First example]
As shown in FIG. 6A, in the first example, the outer periphery 30g of the top end surface of the standing wall 30 is disposed outside the inner periphery 47n of the lower end surface of the protrusion 47, and The inner periphery 30n of the top end surface is arranged on the inner side of the outer periphery 47g of the lower end surface of the protrusion 47.

[Second example]
As shown in FIG. 6B, in the second example as well, the outer periphery 30g of the top end surface of the standing wall 30 is arranged outside the inner periphery 47n of the lower end surface of the protrusion 47 in the same manner as in the first example. In addition, the inner periphery 30 n of the top end surface of the standing wall 30 is disposed on the inner side of the outer periphery 47 g of the lower end surface of the protrusion 47. The difference from the first example is that the standing wall 30 is made thicker and the protrusion 47 is made thinner.

[Third example]
As shown in FIG. 6C, in the third example, the outer periphery 30 g of the top end surface of the standing wall 30 is disposed outside the outer periphery 47 g of the lower end surface of the protrusion 47, and the top end of the standing wall 30. The inner periphery 30n of the surface is disposed inside the inner periphery 47n of the lower end surface of the protrusion 47.

[Fourth example]
As shown in FIG. 6D, the protrusion 47 is not formed in the fourth example. Thereby, the top end surface of the standing wall 30 abuts against the inner surface of the top plate 46 of the hinge cap 40.

  In any case, when the configurations from the first example to the fourth example are adopted, the opening (mouth) formed by the standing wall 30 is sealed, so that the stored mayonnaise leaks inadvertently. It wo n’t happen.

[Comparative example]
On the other hand, as shown in FIG. 6E, in the comparative example, the inner periphery 30 n of the top end surface of the standing wall 30 is disposed on the inner side of the inner periphery 47 n of the lower end surface of the protrusion 47. However, the outer periphery 30g of the top end surface of the standing wall 30 has a portion disposed outside the outer periphery 47g of the lower end surface of the protrusion 47, and is disposed inside the outer periphery 47g of the lower end surface of the protrusion 47. There is also a part.
For this reason, mayonnaise may leak from the portion of arrow A.

FIG. 7 is a diagram showing a first usage method, and FIG. 8 is a diagram showing a second usage method.
The first usage method is a method of using the mayonnaise container 10 by opening the lid 43 of the hinge cap 40, and the second usage method is a method of using the mayonnaise container 10 by removing the hinge cap 40 from the container body 20. . Hereinafter, two methods of use will be described in order.

[First usage]
First, as shown in FIG. 7A, a mayonnaise container 10 filled with mayonnaise is prepared.
Next, as shown in FIG. 7B, the lid 43 of the hinge cap 40 is opened to expose the narrow mouth nozzle 41.
Then, as shown in FIG. 7C, when the body portion of the mayonnaise container 10 is pushed down with the hinge cap 40 down, a thin mayonnaise having a circular cross section is pushed out from the narrow mouth nozzle 41.

[Second usage]
First, as shown in FIG. 8A, a mayonnaise container 10 filled with mayonnaise is prepared.
Next, as shown in FIG. 8B, the hinge cap 40 is removed from the mayonnaise container 10 to expose the standing wall 30.
Then, as shown in FIG. 8C, when the body portion of the mayonnaise container 10 is pushed down with the standing wall 30 down, a thick mayonnaise having a star-shaped cross section is formed from the mouth portion 31 formed by the standing wall 30. Extruded.

FIG. 9 is a schematic diagram showing an arrangement relationship between the split mold used for blow molding and the star shape formed by the standing wall 30.
As shown in FIG. 9A, in the present embodiment, two of the mouth portions 31 having a star-shaped contour having six protrusions formed by the standing wall 30 are arranged in the left-right direction. The protrusions T1 and T2 are made to coincide with the mating surfaces of the divided molds KA. Thereby, the split mold KA can be easily removed after molding.

  On the other hand, as shown in FIG. 9B, in the form of the comparative example, the mouth portion 31 having a star-shaped contour having six protrusions formed by the standing wall 30 is arranged in the left-right direction. The two valleys T3 and T4 are made to coincide with the mating surfaces of the divided molds KB. In this case, the divided mold KB cannot be easily removed after molding.

  As described above, according to the present embodiment, the container body 20 and the upright wall 30 are integrally formed, so the number of parts can be reduced compared to a configuration in which a thin piece having a star-shaped hole is attached later. The manufacturing cost of the mayonnaise container 10 can be reduced.

  Moreover, according to this embodiment, since the standing wall 30 which forms the mouth part 31 which has a star-shaped outline is formed standing up from the upper part of the container main body 20, the up-down direction (top and bottom) It is possible to ensure a long length of the standing wall 30 (mouth portion 31) in the direction).

  As a result, when the container body 20 and the standing wall 30 are integrally molded, not only the container body 20 but also the standing wall 30 can have a wide contact area with the split mold used for blow molding. The shape of the standing wall 30 suitable for molding can be obtained. By adopting such a shape of the standing wall 30, the container main body 20 and the standing wall 30 that forms the mouth portion 31 can be easily formed integrally, and as a result, the manufacturing cost of the mayonnaise container 10 is increased. Can be suppressed.

  Furthermore, in this embodiment, since the top surface 23 is arrange | positioned at the upper part of the trunk | drum 21, and the standing wall 30 is arrange | positioned on the top surface 23, the standing wall 30 is stably arrange | positioned by the foundation called the top surface 23. FIG. be able to. Moreover, since the standing wall 30 can be stored inside the outer periphery of the top surface 23, the standing wall 30 does not get in the way when the hinge cap 40 is attached.

Hereinafter, other embodiments of the present invention will be described. In this description, the same components as those in the first embodiment described above are denoted by the same reference numerals including those shown in the drawings, and redundant description thereof is omitted.
[Second Embodiment]
FIG. 10 is a perspective view of a mayonnaise container 50 according to the second embodiment.
As shown in this figure, the mayonnaise container 50 includes a container body 20 and an upright wall 70. The container body 20 and the upright wall 70 are integrally formed by blow molding or the like, and the configuration and shape of the container body 20 are the same as those of the mayonnaise container 10 according to the first embodiment. The difference from the mayonnaise container 10 is the shape of the standing wall 70.

  The standing wall 70 in the present embodiment has a top end formed in a cylindrical shape. Although the standing wall 70 is formed in a cylindrical shape as a whole, the middle portion viewed in the vertical direction is narrowed down to a star shape having six protrusions, and as a result, a narrowed mouth portion 71 is formed. Yes. And the auxiliary surface 73 extended in the flat plate shape outward from the outer periphery of the mouth part 71 formed by narrowing the intermediate part is a cylindrical shape that forms the top end part of the standing wall 70 formed above the mouth part. The lower end of the auxiliary wall 74 and the upper end of the mouth portion 71 are connected.

  When the shape of the standing wall 70 is taken from another viewpoint, the standing wall 70 in the mayonnaise container 50 having a star-shaped contour having six protrusions does not stand up to its top end with a constant contour. An auxiliary surface 73 extending in a flat plate shape from the outer periphery of the mouth portion 71 and having a circular outline, and an auxiliary wall 74 formed in a cylindrical shape standing upward from the outer periphery of the auxiliary surface 73. In other words.

  FIG. 11 is a plan view, a front view, and a right side view of the mayonnaise container 50. In addition, (A) in FIG. 11 shows a plan view, (B) in FIG. 2 shows a front view, and (C) in FIG. 2 shows a right side view.

  As shown in FIG. 11 (A), when the mayonnaise container 50 is viewed from above, the outer edge of the container body 20 is disposed on the outermost side, and the auxiliary wall 74 is disposed on the inner side thereof. The auxiliary surface 73 and the mouth portion 71 are arranged on the front side. Of the six protrusions forming the mouth portion 71 narrowed down in a star shape, two protrusions T1 and T2 are arranged at positions that overlap the parting line PL in the vertical direction (vertical direction).

  As shown in (B) and (C) of FIG. 11, when the mayonnaise container 50 is viewed from the front and side, the shape thereof is symmetrical with the exception of the screw thread 24. Also from these figures, it can be seen that the two protrusions T1, T2 forming part of the contour of the mouth 71 are formed on the parting line PL.

FIG. 12 is a view showing a state in which the hinge cap 40 is attached to the container body 20. In the drawing, the upper portion of the hinge cap 40 is shown in cross section.
As shown in FIG. 12, when the hinge cap 40 is attached to the container body 20, the top end surface 72 of the auxiliary wall 74 that forms the upper portion of the standing wall 70 comes into contact with the bottom surface of the protrusion 47 of the hinge cap 40.

  Although not particularly illustrated, an aluminum seal is set in advance inside the hinge cap 40 at a stage before the hinge cap 40 is attached to the container body 20. After the mayonnaise container 50 is filled with mayonnaise, the hinge cap 40 is attached and high frequency heating is performed, so that an aluminum seal is welded and attached to the top end surface 72 of the upright wall 70. This aluminum seal is peeled off during use. The annular projecting portion 47 functions as a member that presses the aluminum seal before use, and functions as a member that abuts the top end surface 72 of the upright wall 70 after the start of use.

  In the mayonnaise container 50, since the top end surface 72 of the standing wall 70 is formed in a simple circular shape, compared to the mayonnaise container 10 in which the top end surface is formed in a star shape having six protrusions, The alignment between the protrusion 47 and the top end surface 72 can be performed more easily.

FIG. 13 is a diagram illustrating the relationship between the shape of the top end surface of the standing wall 70 in the mayonnaise container 50 and the shape of the inner surface of the hinge cap 40.
As the shape of the auxiliary wall 74 that forms the top end portion of the standing wall 70 and the shape of the inner surface of the hinge cap 40, preferred shapes can be adopted as appropriate according to applications and circumstances. For example, the following first to third examples are possible. Any of up to can be applied.

  Moreover, in the figure, the state which attached the hinge cap 40 to the container main body 20 is shown. The top end surface of the auxiliary wall 74 is indicated by a solid line, and other members (for example, the bottom surface of the projection 47 of the hinge cap 40, etc.) are indicated by dotted lines.

[First example]
As shown in FIG. 13A, in the first example, the outer periphery 74g of the top end surface of the auxiliary wall 74 is disposed outside the inner periphery 47n of the lower end surface of the protrusion 47, and the auxiliary wall 74 An inner periphery 74 n of the top end surface is disposed on the inner side of the outer periphery 47 g of the lower end surface of the protrusion 47.
By being arranged in this way, with the attachment of the hinge cap 40, the top end surface of the auxiliary wall 74 is brought into contact with the bottom end surface of the protrusion 47 so that pressure is applied to the entire top end surface of the auxiliary wall 74. .

[Second example]
As shown in FIG. 13B, in the second example, the outer periphery 74 g of the top end surface of the auxiliary wall 74 is arranged outside the outer periphery 47 g of the lower end surface of the protrusion 47, and the top end of the auxiliary wall 74. The inner periphery 74n of the surface is disposed on the inner side than the inner periphery 47n of the lower end surface of the protrusion 47.
The difference from the first example is that the auxiliary wall 74 is thicker and the protrusion 47 is thinner. With the attachment of the hinge cap 40, the top end surface of the auxiliary wall 74 formed in this manner abuts so as to cover the entire lower end surface of the protrusion 47, so that the top end surface of the auxiliary wall 74 has its inner edge and Pressure is applied to an annular portion having a certain width between the outer edge and the outer edge.

[Third example]
As shown in FIG. 13C, in the third example, the protrusion 47 is not formed on the inner surface of the hinge cap 40. Therefore, when the hinge cap 40 is attached, the top end surface of the auxiliary wall 74 and the top plate 86 of the hinge cap 40 come into contact with each other, and pressure is applied to the top end surface of the auxiliary wall 74 in a state where the top plate 86 is entirely covered. It becomes.

  When the configurations from the first example to the third example are adopted, when the hinge cap 40 is attached to the container body 20, the projection 47 and the top end surface of the auxiliary wall 74 are set in advance inside the hinge cap 40. While abutting with a seal (not shown) interposed therebetween, a pressure accompanying tightening of the hinge cap 40 is applied. In a later step, this contact portion is heated at high frequency, so that an aluminum seal is securely welded to the top end surface of the auxiliary wall 74 with the opening (mouth) formed by the standing wall 70 completely closed. Can be made.

  Thus, since the opening formed by the standing wall 70 is sealed with the aluminum seal, there is no fear of the stored mayonnaise leaking inadvertently, and the barrier property of the mayonnaise container 50 is maintained until immediately before its use. It becomes possible.

  FIG. 14 is a schematic diagram showing an arrangement relationship between the split mold KA used for blow molding of the mayonnaise container 50 and the star shape formed in the middle part of the upright wall 70.

(A) in FIG. 14 is a view of the state before removing the divided mold KA after the mayonnaise container 50 is molded, as viewed from the plane side. As shown in this figure, the mayonnaise container 50 is formed symmetrically with respect to the mating surfaces of the upper and lower divided molds KA.
Further, of the six protrusions forming the star-shaped contour of the mouth portion 71, the two protrusions T1 and T2 arranged in the left-right direction are made to coincide with the mating surfaces of the upper and lower divided molds KA. Thereby, the split mold KA can be easily removed after molding.

  On the other hand, (B) in FIG. 14 is a view of a split mold KB with different positions of projections forming the star-shaped contour of the mouth portion 71 as seen from the plane side as a comparative example. In this divided mold KB, two valleys T3 and T4 arranged in the left-right direction among the six valleys forming the star-shaped contour of the mouth 71 are made to coincide with the mating surfaces of the upper and lower divided molds KB. Yes.

  In this case, the protrusions formed on both sides of the two valleys T3 and T4 prevent the movement of the mold part forming the cavity imitated by the shape of the two valleys T3 and T4. It becomes difficult to remove the mold KB. In order to avoid such a situation, the split mold KA shown in (A) is used in the present embodiment.

  FIG. 15 is a schematic view showing a state where the discarded bag of the mayonnaise container 50 is cut after blow molding. In FIG. 15, (A) shows the operation of the rotary blade RC at the time of cutting the discarded bag. 15B is a top end portion of the auxiliary wall 30 of the first embodiment, and FIG. 15C is a top end portion of the auxiliary wall 74 (standing wall 70) of the second embodiment. It shows how to do.

  From the viewpoint of hygiene, the blow-molded mayonnaise container 50 is placed in a state where the discarded bags are connected to the upper part of the auxiliary wall 74 until just before the mayonnaise is filled in the container. When cutting the discarded bag, the mayonnaise container 50 is first gripped in an upside down state so as not to allow scraps, dust, etc. generated by the cutting to enter the container.

  FIG. 15A is a view of the mayonnaise container 50 gripped upside down as seen from below. In this state, the rotary blade RC formed in a disk shape enters a portion that hits the top end portion of the auxiliary wall 74 (that is, the top end portion of the standing wall 70), and the rotary blade RC hits the blade edge while moving in the circumferential direction. Cut the part. Then, when the rotary blade RC makes one round along the upright wall 70, the entire disposal bag is cut off and the top end surface of the auxiliary wall 74 is formed.

  As shown in FIG. 15 (B), the standing wall 30 of the mayonnaise container 10 according to the first embodiment is formed in a star shape having an outline with six protrusions, and the rotary blade RC stands upright. After entering the portion corresponding to the top end of the wall 30, the protrusions and the valleys formed between the two protrusions are alternately cut. When the entire disposal bag is cut off, the top end face 32 is formed.

  On the other hand, as shown in FIG. 15C, the auxiliary wall 74 of the mayonnaise container 50 according to the second embodiment has a substantially circular outline and a simple shape. The degree of contact between the cutting edge and the auxiliary wall 74 in the process of making a round after entering the portion corresponding to the top end of the auxiliary wall 74 is constant. Therefore, it is possible to smoothly form the top end surface 72 by allowing the rotary blade RC to enter smoothly.
