Description

The present invention is a drink container made of resin, glass, ceramics, etc., called cups, tea bowls, mugs, tumblers, etc., used when drinking soft drinks, alcoholic drinks, coffee, other drinks, It relates to an improved stacking characteristic at the time of storage, drainage at the time of stacking and storing after washing, and visual interest.

Tableware including a drinking container not only provides a function as a container, but also has a role of providing an environment suitable for enjoying food and drink by visual interest and hand feeling including the outer shape design of the container. In this sense, there is a specific demand different from other general packaging containers or storage containers for the visual interest and hand feeling of tableware.

In addition, the types of tableware including drinking containers are extremely diverse, corresponding to the diversity of food and drinks.
For this reason, the number of tableware to be stored in the cupboard is enormous, not only for food and beverage suppliers but also for general households. For this reason, the tableware is also required to have good storage properties during storage.

Regarding the storage of tableware, dishes, bowls, and bowls can be easily stacked, but in drinking containers such as cups, cups and mugs, various problems arise due to stacking. Also, depending on the position of the handle, such as a mug with a handle, the handle may be hindered and stacking may not be possible in the first place.

The problem that occurs when stacking and storing a drinking container is that the drinking container is intended to store the liquid, so the bottom of the side wall that is usually applied in a mode in which the diameter from the mouth diameter to the bottom diameter gradually decreases. This is because the aperture taper is set very slightly. That is, the accumulated weight when a large number of drinking containers having a small bottom squeeze taper rate are stacked generates a radial component component by the taper of the side wall, and the generated radial component component has a small taper factor. It has a relationship of becoming larger. Therefore, when the upper container functions like a wedge with respect to the lower container, the side walls of the drinking containers stacked on top of each other are fitted with an unexpectedly large surface pressure, which is very common for tableware. Scratches, cracks,
Cracks will occur.

In addition, in the case of stacking storage of drinking containers, in addition to stacking the drinking containers in an upward position, it is not uncommon for the drinking containers to be stacked in a lying position. There is a problem that moisture during the cleaning is trapped and the inside becomes unsanitary. This problem can be prevented by performing sufficient wiping and drying prior to stacking and storage, but it is a heavy work burden for the user of the drinking container when busy.

The existence and cause of the above-described problems related to stacking storage of drinking containers have been widely known, and various proposals have been made for this problem (see the following patent document).

Utility Model Registration No. 3125080 JP 2001-31051 A JP-A-7-329948 Utility Model Registration No. 3020759 Japanese Utility Model Publication No. 50-146901 Japanese Utility Model Publication No. 6-12330 Japanese Utility Model Publication No. 51-20574 Japanese Utility Model Publication No. 53-58886

The proposals exemplified in the above-mentioned patent documents can be classified into several groups based on the essential features of the proposals, but each of the classifications generally includes the following problems.

In the case of a drinking container having a high plateau (see Patent Document 1), by appropriately setting the outer diameter of the high plateau and the inner diameter of the mouth portion, the height of the upper container is dropped into the mouth of the lower container. Stable stacking is possible. However, the hills are derived from the traditional design of pottery and tend not to meet the sophisticated modern design demands for drinking containers.

Proposals for forming an annular receiving step on the inner peripheral surface of the drinking container and receiving the upper stacking container at this part (see Patent Documents 2 and 3) are difficult to apply to drinking containers with a straight design with a small bottom squeeze taper rate. It is. When a receiving step portion having an effective protrusion amount for supporting the upper stacking container is projected on the inner peripheral surface of the drinking container having a small bottom squeeze taper, the inner peripheral surface below the receiving step portion becomes non-tapered or reverse tapered, Difficulties arise in releasing the molded product from the mold during molding (see FIGS. 3 and 4 of Patent Document 3).

Proposal of forming an annular receiving step on the outer peripheral surface of the drinking container and stacking this part on the mouth of the lower container (see Patent Document 4), depending on the skill of the design, is annular on the outer peripheral surface. Since there is no choice but to have an appearance with a step, there is a problem of further restricting the design freedom in the drinking container industry, which has spread the problem that the design freedom is not so large. Even if the band-like protrusions are stacked so as to drop into the lower container, the same can be said (see Patent Document 5).

A proposal in which a plurality of ribs are provided on the outer peripheral surface of the drinking container so that the outer peripheral surface of the upper container is brought into contact with the inner peripheral surface of the lower container via the plurality of ribs (see Patent Document 6). This is a proposal that pays attention only to the prevention, and the accumulated weight when many are stacked concentrates on multiple points of the lower container via ribs, so this may depend on the material and surface finish of the drinking container. The evils caused by will be unavoidable.

A drinking container having an extreme stepped portion in which a large-diameter drinking container and a small-diameter drinking container are connected to each other in the middle of the container (see Patent Documents 7 and 8), the stepped portion is only a large area, As a result, the positioning function of the upper and lower containers in a state where the containers are stacked up and down is lost (see Patent Document 7).
For this reason, it is necessary to take measures so that a part of the small-diameter portion bulges out so that the small-diameter portion does not move freely within the large-diameter portion (see Patent Document 8). Presents.

In addition, the problem of becoming unsanitary when water is trapped between the upper and lower containers when the drinking containers are stacked and stored is caused by the fact that the interior between the upper and lower containers is hermetically sealed. Furthermore, with regard to stacked storage in a lying position, in a drinking container in the form of having an annular platform for obtaining stable seating on the outer periphery of the bottom of the drinking container, and in a drinking container having a form of a raised bottom type However, since water is stored in the shape of the bottom surface, this is a particular problem. However, no effective countermeasures have been taken except for a container that is not suitable as a drinking container (see Patent Document 6).

The present invention recognizes the above-mentioned proposal examples related to stacking storage of drinking containers and the problems that each proposal may bring, and is a fundamental issue in the industry for drinking containers from a completely new point of view. Aiming to realize a wealth of fun as a drinking container at the time, ease of stacking and storage, and ensuring hygiene during stacking and storage without sacrificing a normal appearance. To do.

In order to achieve the above object, the present invention provides a drinking container based on a square shape and a drinking container based on a round shape, or a combination of these and a round-cornered drinking container with predetermined conditions. Combined below and geometrically synthesized, so that eventually a part of the square drinking container protrudes from the outer peripheral surface of the round drinking container, the rectangular drinking container, or the rounded corner drinking container By combining them in a manner that remains in the box, it is possible to use a plurality of corners of the protruding rectangular container to achieve stable and easy stacking without generating wedge-like expansion force, and in the case of stacking and storing, the hygienic condition Providing an entertaining container that has both ventilation and drainage, which are indispensable for ensuring safety, and has the appeal of being able to see both a round container and a square container depending on the angle of observation when using the container. It is.

  The present invention adopts the following configuration as means for achieving the above object.

(Solution 1)
The drinking container of the present invention comprises a side wall having a circular mouth shape and a bottom surface having a circular bottom shape, and the mouth diameter is continuous from the mouth diameter, which is the diameter of the mouth, to the bottom face diameter, which is the diameter of the bottom surface. The mouth shape, which is the diameter of the circumscribed circle of the mouth, is composed of a side wall with a polygonal mouth shape and a bottom surface with a polygonal bottom shape. The aperture is not more than the aperture diameter of the first basic three-dimensional shape, and the bottom aperture, which is the diameter of the circumscribed circle of the bottom surface, is an arbitrary intermediate value between the aperture diameter of the first basic three-dimensional shape and the bottom aperture, A rectangular drinking container-like solid shape in which the height of the wall is set to be less than the height of the side wall of the first basic three-dimensional shape is defined as a second basic three-dimensional shape, and the first basic three-dimensional shape and the second basic three-dimensional shape, Align the central axis of the first basic 3D shape mouth height position Assuming that the height positions of the mouths of the second basic three-dimensional shape are aligned and overlapped, the remaining three-dimensional shape remaining when the portion belonging to the first basic three-dimensional shape is removed from the second basic three-dimensional shape It has a three-dimensional shape, and is formed of a three-dimensional shape corresponding to an integral molding of the first basic three-dimensional shape and the third basic three-dimensional shape.

The drinking container of the present invention is designed to leave both the characteristics of a round drinking container and the characteristics of a square drinking container by a geometric synthesis method.

Specifically, the reference container of the present invention has a form in which a first basic solid shape and a third basic solid shape are integrally formed. The third basic three-dimensional shape at this time is created from the relationship between the first basic three-dimensional shape and the second basic three-dimensional shape.

  The first basic three-dimensional shape is a three-dimensional shape of a round drinking container. This three-dimensional shape consists of a side wall with a circular mouth shape and a bottom surface with a circular bottom shape, and the diameter of the mouth continuously changes from the mouth diameter, which is the diameter of the mouth, to the bottom face diameter, which is the diameter of the bottom surface. It is a common shape of a drinking container with a so-called bottom-squeezing taper that gradually decreases.

  The second basic three-dimensional shape is a general three-dimensional shape of a square drinking container. This three-dimensional shape is composed of a side wall with a square shape at the mouth shape and a bottom surface with a square shape at the bottom surface. The relationship between the first basic three-dimensional shape is that the mouth diameter, which is the diameter of the circumcircle of the mouth, is the first The bottom diameter, which is equal to or less than the diameter of the base diameter of the basic three-dimensional shape and is the diameter of the circumscribed circle of the bottom surface, is an arbitrary intermediate value between the mouth diameter of the first basic three-dimensional shape and the bottom diameter, and the height of the side wall is The shape is set to be less than the height of the side wall of one basic solid shape, and the corners of the side wall are rounded. That is, it is the shape of a square drinking container that is also common in the second basic three-dimensional shape.

  The third basic three-dimensional shape is a remaining three-dimensional shape that remains when it is assumed that the portion belonging to the first basic three-dimensional shape is removed from the second basic three-dimensional shape. Here, the portion belonging to the first basic three-dimensional shape with respect to the second basic three-dimensional shape means that the first basic three-dimensional shape and the second basic three-dimensional shape are made to coincide with the center axis of modeling, and the height of the mouth of the first basic three-dimensional shape is high. This is the meaning of the portion that is included in the outer shape of the first basic three-dimensional shape when it is assumed that the height position and the height position of the mouth of the second basic three-dimensional shape are aligned and overlapped. And when it assumes that the part which will be contained in the 1st basic solid shape was removed, the remaining part which remains is a 3rd basic solid shape. The third basic three-dimensional shape generally exhibits a trigonal pyramid shape having a very low height with the bottom corner of the rectangular drinking container being the second basic three-dimensional shape as the apex, and the second basic three-dimensional shape. It becomes a shape separated into a plurality corresponding to the number of corners.

  The outer shape of the drinking container of the present invention is a three-dimensional shape corresponding to a three-dimensional shape obtained by integrally molding the first basic three-dimensional shape and the third basic three-dimensional shape as described above. In other words, the outer shape of the side wall of the round drinking container has an outer shape in which the side wall of the square drinking container partially appears. This makes it possible to see both the round drinking container and the square drinking container depending on the observation angle. Four visual effects are realized.

  In addition, since the height of the side wall in the second basic three-dimensional shape is set to be less than the height of the side wall of the first basic three-dimensional shape, the side wall of the round drinking container inevitably has a square shape. The bottom corner portion of the drinking container will protrude with a step. Therefore, when stacking the drinking containers of the present invention, the protruding bottom corner portion of the square drinking container can be used as a step.

(Solution 2)
The drinking container of the present invention comprises a side wall having a circular mouth shape and a bottom surface having a circular bottom shape, and the mouth diameter is continuous from the mouth diameter, which is the diameter of the mouth, to the bottom face diameter, which is the diameter of the bottom surface. The three-dimensional shape of a round drinking container that gradually decreases to a first basic three-dimensional shape is composed of a side wall having a circular mouth shape and a bottom surface having a polygonal bottom surface shape. The bottom face diameter, which is equal to or smaller than the diameter of the base diameter of one basic solid shape and is the diameter of the circumscribed circle of the bottom face, is an arbitrary intermediate value between the mouth diameter and the bottom face diameter of the first basic solid shape, and the height of the side wall Is set to be less than the height of the side wall of the first basic three-dimensional shape, and the three-dimensional shape of the round-cornered composite drinking container is defined as the second basic three-dimensional shape, and the first basic three-dimensional shape and the second basic three-dimensional shape Align the central axis of the first basic 3D shape mouth height position Assuming that the height positions of the mouths of the second basic three-dimensional shape are aligned and overlapped, the remaining three-dimensional shape remaining when the portion belonging to the first basic three-dimensional shape is removed from the second basic three-dimensional shape It is a three-dimensional solid shape, and is composed of a three-dimensional shape corresponding to an integral molding of the first basic three-dimensional shape and the third basic three-dimensional shape.

  The first basic three-dimensional shape in the above configuration is the same as that in the solving means 1, and the second basic three-dimensional shape is different from that in the solving means 1. Further, the difference with respect to the second basic three-dimensional shape is only the mouth shape. That is, the mouth shape of the second basic three-dimensional shape in the solving means 1 is a polygon, whereas in the present invention, a circular mouth shape is adopted. Other conditions for the first basic three-dimensional shape are the same.

  The said structure has shown the different means with the effect substantially the same as the solution means 1. FIG. Since the mouth diameter of the second basic three-dimensional shape is required to be equal to or less than the mouth diameter of the first basic three-dimensional shape, it is finally formed even if the mouth shapes of the second basic three-dimensional shape are different. This is because it is not expressed as the mouth shape of the drinking container.

(Solution 3)
The drinking container of the present invention comprises a side wall having a circular mouth shape and a bottom surface having a polygonal bottom shape, and the diameter is changed from the mouth diameter, which is the diameter of the mouth, to the bottom face diameter, which is the diameter of the circumscribed circle of the bottom surface. A round corner composite drinking container-like three-dimensional shape that gradually and gradually decreases without a step is a first basic three-dimensional shape, consisting of a side wall with a polygonal mouth shape and a bottom surface with a polygonal bottom shape. The diameter of the circle, which is the diameter of the circle, is less than or equal to the diameter of the mouth of the first basic three-dimensional shape, and the bottom diameter, which is the diameter of the circumscribed circle of the bottom surface, is arbitrarily set between the mouth diameter of the first basic three-dimensional shape and the diameter of the bottom surface And the square shape of the drinking container shape in which the height of the side wall is set to be less than the height of the side wall of the first basic three-dimensional shape as the second basic three-dimensional shape,
The first basic three-dimensional shape and the second basic three-dimensional shape are made to coincide with each other in a central axis, the height position of the mouth of the first basic three-dimensional shape is aligned with the height position of the mouth of the second basic three-dimensional shape, When it is assumed that the corner portions are overlapped in correspondence, the remaining three-dimensional shape remaining when the portion belonging to the first basic three-dimensional shape is removed from the second basic three-dimensional shape is defined as the third basic three-dimensional shape, It is characterized by comprising a three-dimensional shape corresponding to an integral molding of one basic solid shape and the third basic solid shape.

  The first basic three-dimensional shape in the above configuration is the shape of a round-cornered drinking container having a circular mouth shape and a polygonal bottom shape. That is, the circular mouth shape gradually changes to a polygonal shape toward the bottom surface. It is unclear whether or not a drinking container having such a shape exists, but the production itself is easy. The second basic three-dimensional shape is a shape of a general square drinking container. Other conditions are the same as those of Solution 1.

  The first basic three-dimensional shape and the second basic three-dimensional shape are overlapped with each other so as to correspond to the corners of the side wall. As a result, when the portion belonging to the first basic three-dimensional shape is removed from the second basic three-dimensional shape and the removed remaining part is integrated into the first basic three-dimensional shape, each corner of the side wall of the first basic three-dimensional shape A three-dimensional drinking container in which the corners of the side walls of the second basic three-dimensional shape are stacked is formed. At this time, since the height of the side wall of the second basic three-dimensional shape is less than the height of the side wall of the first basic three-dimensional shape, the height of the side wall is formed at each corner of the formed drinking container. A step in which the bottom corner portion of the second basic three-dimensional shape protrudes is formed at any of the positions.

  The step formed as described above can be used as a receiving step when stacking and storing drinking containers. Here, the mouth shape of the reference container finally formed is circular, but the cross-sectional shape of the portion other than the mouth is a shape other than the circle included in the mouth diameter. That is, any shape in the process of gradually changing from a circular mouth shape to a polygonal shape. Therefore, when the drinking containers are stacked using the formed steps, a gap is formed between the upper and lower drinking containers stacked so that outside air can communicate. Accordingly, moisture that may be present between the stacked drinking containers is discharged through the outside air communicating with the gap.

(Solution 4)
The present invention consists of a side wall with a circular mouth shape and a bottom surface with a polygonal bottom surface. The diameter is continuous from the mouth diameter, which is the diameter of the mouth, to the bottom face diameter, which is the diameter of the circumscribed circle of the bottom. The mouth diameter is the diameter of the mouth, consisting of a side wall with a rounded mouth shape and a bottom face with a polygonal bottom shape, and a three-dimensional shape of a round-cornered composite drinking container that gradually decreases gradually. Is a caliber equal to or less than the mouth diameter of the first basic three-dimensional shape, and the bottom face diameter, which is the diameter of the circumscribed circle of the bottom face, is an arbitrary intermediate value between the mouth diameter and the bottom face diameter of the first basic three-dimensional shape, The round three-dimensional drinking container-shaped three-dimensional shape formed by setting the height of the first basic three-dimensional shape to be less than the height of the side wall of the first basic three-dimensional shape is the second basic three-dimensional shape, and the first basic three-dimensional shape and the second basic three-dimensional shape Match the center axis of the 3D shape with the mouth height of the 1st basic 3D shape When the vertical position is aligned with the height position of the mouth of the second basic three-dimensional shape, and the corners of the side walls are made to correspond to each other, the portion belonging to the first basic three-dimensional shape is defined as the second basic three-dimensional shape. The remaining three-dimensional shape remaining when removed from the shape is the third basic three-dimensional shape,
The first basic solid shape and the third basic solid shape are integrally formed of a solid shape.

  The above configuration shows the condition of the second basic three-dimensional shape that can achieve substantially the same operational effects as the configuration of the solving means 3. The only difference from the solution 3 is the mouth shape of the second basic three-dimensional shape, and the other conditions are the same. This is because the mouth shape of the second basic three-dimensional shape is not expressed as the mouth shape of the drinking container that is finally formed, as described with reference to the solving means 2.

(Solution 5)
The present invention is based on the invention described in Solution 3 or Solution 4 above, and the bottom surface of the first basic three-dimensional shape is a portion other than the outer peripheral portion which leaves the outer peripheral portion of the bottom surface in an annular shape with a predetermined width. And at least one portion of the annular base is cut out at an intermediate position between the adjacent corners of the side wall of the second basic three-dimensional shape. It is characterized by forming.

  The above means for solving the problem that when drinking containers having an annular base on the bottom surface are stacked and stored in a lying position, the water staying on the bottom surface is trapped for a long time between the stacked drinking containers and becomes unsanitary. Is shown. The annular platform in the drinking container is not a special one, and is a means for improving the seating property on a table surface or the like widely used in general drinking containers.

  That is, the drinking container which is the basic invention of the present invention is devised so that a gap is formed between the upper and lower drinking containers when stacked, as described with reference to the solution means 3. This measure is sufficient when the amount of water trapped between stacked drinking containers is small, but in drinking containers that have an annular platform on the bottom, a large amount of water blocked by the annular platform due to the prone posture Only when the water remains on the bottom surface and a gap is provided between the upper and lower drinking containers, a sufficient effect cannot be obtained. Therefore, by providing a drainage groove in which the annular base is cut out corresponding to the position where the gap is generated, the water remaining on the bottom surface can be quickly led out of the drinking container from the drainage groove through the gap. It is. In other words, the present invention is based on the invention described in Solution 3 in which a gap is generated between the upper and lower drinking containers that are stacked. In addition, the position where a gap is generated when the drinking containers are stacked is an intermediate position between adjacent corners of the side wall of the second basic three-dimensional shape.

(Solution 6)
The drinking container of the present invention includes a handle on the side wall, and the handle is attached within the range of the height of the side wall of the second basic three-dimensional shape.

  When the drinking container is provided with a handle such as a mug, for example, the conditions regarding the attachment position of the handle are shown. The handle becomes an obstacle when stacking drinking containers. The drinking container according to the present invention realizes a reasonable and stable stacking state by utilizing a step formed when the first basic three-dimensional shape and the third basic three-dimensional shape are integrally formed. Therefore, when there is a handle, the step needs to be formed on the bottom side of the handle. Further, the step is formed by the bottom corner portion of the second basic three-dimensional shape. Therefore, by providing the position of the handle within the range of the height of the side wall of the second basic three-dimensional shape, the position of the step can be positioned on the bottom side from the handle.

The three-dimensional shape of a round drinking container shape is a first basic three-dimensional shape, and the three-dimensional shape of a square drinking container shape or a round-cornered composite drinking container shape is a second basic three-dimensional shape. The side wall can display visual and morphological characteristics as a round drinking container and visual and morphological characteristics as a square drinking container. Therefore, depending on the viewing angle, the round drinking container Both corners of the square-shaped drinking container appearing in a projecting state on the outer peripheral wall of the drinking container, and the bottom corner of the rectangular drinking container does not generate wedge-like expansion force when stacked. Therefore, a large number of drinking containers can be stacked and stored easily and stably.

The three-dimensional shape of the round-cornered composite drinking container shape is the first basic three-dimensional shape, and the three-dimensional shape of the square-shaped drinking container shape or the round-cornered composite drinking container shape is formed as the second basic three-dimensional shape. ,
Similar to the above, it has an interesting visual effect that can be received as a round drinking container or a square drinking container depending on the viewing angle, and is stable using a step based on the difference between the first basic solid shape and the second basic solid shape. Can be realized. In addition, the shape of the upper and lower drinking containers at the positions where they come into contact with each other in the stacked state is a combination of a circle and a polygon, and a gap is inevitably generated between the two, which impairs the ease of stable stacking. In addition, it is possible to allow outside air to communicate between the upper and lower drinking containers that are stacked, and it is possible to solve the problem at the time of stacking and storing that moisture tends to be trapped in the internal space and become unsanitary.

Hereinafter, embodiments of the drinking container of the present invention will be described with reference to the drawings. In addition, since the external shape of the drinking container of this invention is systematically determined according to a fixed design rule, first, the design rule is demonstrated. There are four basic design rules.

(Design rule 1)
First, the mouth diameter A1 which is the diameter of the mouth 1A is within the range of the height A3 of the side wall 2A and the bottom surface 3A.
The first basic three-dimensional shape 10 </ b> A in the shape of a round drinking container is set as a base that gradually decreases to the bottom diameter A <b> 2, which is the diameter of the diameter (FIG. 1).

Next, the mouth diameter B1 which is the diameter of the circumscribed circle S1 of the mouth 1B is equal to or less than the mouth diameter A1 of the first basic three-dimensional shape 10A, and the height B3 of the side wall 2B is the height A3 of the first basic three-dimensional shape 10A.
The second lower of the square-shaped drinking container having an arbitrary number of corners having a bottom diameter B2 which is a diameter of the circumscribed circle S2 of the bottom surface 3B and an arbitrary intermediate value between the base diameter A1 and the bottom diameter A2 of the first basic three-dimensional shape 10A. A basic three-dimensional shape 10B is set (FIG. 2). This square drinking container-like second basic three-dimensional shape 10
About B, the shape which rounded the corner | angular part largely is preferable.

Here, it is assumed that the first basic three-dimensional shape 10A and the second basic three-dimensional shape 10B are superposed with their center axes CL coincident and the height positions of the mouth 1A and the mouth 1B are aligned (FIG. 3). Second
The remaining part when it is assumed that the part to which the first basic three-dimensional shape 10A belongs is removed from the basic three-dimensional shape 10B is defined as a third basic three-dimensional shape 10C (FIG. 4). The third basic three-dimensional shape 10C is an irregular cone-shaped corner piece C separated into a number corresponding to the number of corners of the second basic three-dimensional shape 10B, which is square.
Remains as. Here, the case where the mouth diameter A1 of the first basic three-dimensional shape 10A and the mouth diameter B1 of the second basic three-dimensional shape 10B are the same is illustrated.

Then, the three-dimensional shape assuming that the third basic three-dimensional shape 10C is integrally formed with the first basic three-dimensional shape 10A determines the outer shape of the drinking container of the present invention based on the design rule 1. In addition, about the thickness etc. of a drinking container, it mentions later in description of a specific embodiment.

(Design rule 2)
The first basic three-dimensional shape 10A in the design rule 2 is the same as that in the design rule 1 (FIG. 1), but the second basic three-dimensional shape 10B is different (FIG. 5). The second basic three-dimensional shape 10B used in the design rule 2 is a three-dimensional shape of a round-cornered composite drinking container in which the shape of the mouth 1B is circular and the shape of the bottom surface 3B is polygonal.

The mouth diameter B1 and the bottom face diameter B of the second basic three-dimensional shape 10B with respect to the first basic three-dimensional shape 10A.
2. The conditions regarding the height B3 of the side wall 2B are the same as those of the design rule 1. It is assumed that the second basic three-dimensional shape 10B having such a three-dimensional shape is overlapped (FIG. 6), and the remaining portion when it is assumed that the part to which the first basic three-dimensional shape 10A belongs is removed from the second basic three-dimensional shape 10B. Is a third basic three-dimensional shape 10C (FIG. 7).

The third basic three-dimensional shape 10C remaining in this case becomes odd-shaped corner pieces C separated into a number corresponding to the number of corners of the bottom surface 3B of the second basic three-dimensional shape 10B. Each corner piece C is actually a corner of the second basic solid shape 10B, and the mouth shape of the first basic solid shape 10A and the second basic solid shape 1
Since the mouth shape of 0B is the same, it becomes a curved three-dimensional shape in which the width decreases while the thickness increases downward.

The three-dimensional shape in the case where it is assumed that the third basic three-dimensional shape 10C formulated in this way is integrally formed with the first basic three-dimensional shape 10A determines the outer shape of the drinking container of the present invention based on the design rule 2. Become.

(Design rule 3)
The first basic three-dimensional shape 10A used for the design rule 3 is a three-dimensional shape of a round-cornered composite drinking container in which the shape of the mouth 1A is circular and the shape of the bottom surface 3A is polygonal (FIG. 8). First
The mouth diameter A1 in the basic three-dimensional shape 10A is the bottom surface 3A within the range of the height A3 of the side wall 2A.
Is gradually reduced to the bottom diameter A2, which is the diameter of the circumscribed circle S2.

On the other hand, the second basic solid shape 10B is the same as the second basic solid shape 10B of the design rule 1 (see FIG. 2, FIG. 9). That is, this case is characterized in that the first basic three-dimensional shape 10A is different from the case of the design rule 1. Both mouth diameters A1 and B1 are the same, and the second
The bottom face diameter B2 of the basic three-dimensional shape 10B is set to an arbitrary intermediate value between the mouth diameter A1 and the bottom face diameter A2 of the first basic three-dimensional shape 10A. Further, the height B3 of the side wall 2B of the second basic three-dimensional shape 10B is less than the height A3 of the side wall 2A of the first basic three-dimensional shape 10A (FIG. 8,
FIG. 9).

If it is assumed that the first basic three-dimensional shape 10A and the second basic three-dimensional shape 10B having such a relationship are overlapped with the height positions of the mouths 1A and 1B of both the same, the second basic three-dimensional shape 1
Part of the side wall 2B of 0B, specifically, the side wall 2 of which the corner portion is the first basic three-dimensional shape 10A
It will be in the state which protrudes from A (FIG. 10). That is, this protruding portion is the third basic three-dimensional shape 1
Corner pieces C constituting 0C.

(Design rule 4)
A round-angle compound drinking container-like three-dimensional shape is used for both the first basic three-dimensional shape 10A and the second basic three-dimensional shape 10B (FIGS. 10 and 11). The difference between the two is the bottom diameters A2 and B2 and the heights A3 and B3 of the side walls 2A and 2B. By superimposing both, the corner pieces C constituting the third basic three-dimensional shape 10C can be obtained.

Hereinafter, specific embodiments formed based on the design rules will be described. The design rule of the present invention can be widely applied to various types of drinking containers provided on the market. The same applies to the material as well as the form. However, the degree of suitability varies, and the most preferred material is synthetic resin. In the case of a synthetic resin, the color of the fabric can be adjusted by mixing the pigment with the resin, the painting can be easily performed, and a resin compatible with a microwave oven has been developed.

Drinking container 10D is a mug formed based on design rule 1 (FIG. 12).
, FIG. 13). The drinking container 10 has an outer shape in which a handle 4 is attached to a general cup-shaped body with a bottom diaphragm taper composed of a side wall 2 having a circular shape of the mouth 1 and a circular bottom surface 3.

At the four corners of the side wall 2 of the drinking container 10D, rounded corners 5 of the second basic three-dimensional shape 10B, which are corner pieces C determined by design rules 1 by being distributed at equal angles, protrude.
The apex portion 5T of each rounded corner 5 has a clear step between the other portion of the side wall 2 of the drinking container 10D. The handle 4 is located on the side of the mouth 1 from this step. An annular table 6 is formed on the bottom surface 3 of the drinking container 10D so as to be stably placed on a table surface or the like.

The longitudinal cross-sectional shape of the drinking container 10D as described above appears in two ways depending on the cutting position (FIGS. 14 and 15). FIG. 14 is a vertical cross-sectional shape cut at the XX line position of FIG. 13, that is, at a position not including the corresponding rounded corner portions 5 and 5 across the central axis CL, and is smaller in diameter than the mouth diameter D1. It has a bottom diameter D4 and has a general round drinking container shape in which the diameter gradually decreases from the mouth 1 toward the bottom 3 without any step. The rounded corners 5 are not represented in this vertical cross-sectional shape. Therefore, as long as it observes from this viewing angle, drinking container 10D is observed as a round drinking container.

FIG. 15 shows the Y-Y line position of FIG.
5 is a vertical cross-sectional shape cut at a position including 5, and from this viewing angle, it generally exhibits an appearance as a rectangular drinking container.

The mouth inner diameter D2 of the drinking container 10D is dimensioned so as to be slightly larger than the intermediate outer diameter D3 at the position immediately below the rounded corners 5 (FIG. 15). Therefore, a plurality of drinking containers 10D, 10D can be stably stacked in an arbitrary number so that the following corners 5 of the upper drinking container 10D are dropped into the mouth 1 of the lower drinking container 10D. (FIG. 16).

Next, an example of a mug-type drinking container 10E based on the design rule 3 will be described (FIG. 1).
7, FIG. 18). This drinking container 10E is similar to the drinking container 10D at first glance. However, in the drinking container 10E based on the design rule 3, the first basic three-dimensional shape 10A is based on the three-dimensional shape of a round-angle compound drinking container, It is formed by combining the three-dimensional shape of the type drinking container.

Therefore, rounded corners 5 are expressed on the side wall 2 of the drinking container 10E. An annular base 6 is formed on the bottom surface 3 of the drinking container 10E, and the annular base 6 is cut out at two locations to form drainage grooves 6G and 6G. At this time, each drain groove 6G is positioned in the middle between the adjacent corner portions 5 and 5.

The amount of protrusion of the rounded corners 5 ... protruding from the side wall 2 of the drinking container 10E is slight, but the step formed by the rounded corners 5 ... has a plurality of drinking containers 10E, 10E as described above.
It can function as a receiving stage at the time of stacking and storing (FIG. 19).

In the drinking container 10E of this form, a special hygiene effect can be achieved particularly when stacked and stored in a lying position. That is, when the rounded corners 5 ... function as a receiving stage, the upper drinking container 10 is placed on the apex portion 5T of each rounded corner 5 ... of the lower drinking container 10E.
Stacked in such a manner that the mouth 1 of E is placed. While the shape of the mouth 1 in the drinking container 10E is circular, the side surface 2 of the drinking container 10E in which the step by the rounded corner 5 is formed is
It is a shape close to a square shape. Therefore, gaps F and F are always generated between the side surface 2 of the lower drinking container 10E and the mouth 1 of the upper drinking container 10E. Therefore, the water | moisture content between the upper and lower drinking containers 10E and 10E lose | disappears with the external air which communicates through the clearance gaps F and F. FIG.
In addition, the moisture that tends to stay inside the annular base 6 when it is in the down position flows down through the drain grooves 6G and 6G and is discharged early through the gaps F and F.

The drain grooves 6G and 6G can be installed even in the case of the drinking container 10D shown in FIG. The rounded corner portion 5 of the second three-dimensional shape 10B is in contact with the mouth 1 on the other side stacked so as to be covered, but the mouth 1 is slightly in the middle of the rounded corner 5 having a fixed distance from each other. Since there is a gap, the same effect is obtained.

The present invention does not exclude application to lacquerware products. For example, by combining a square-shaped second basic three-dimensional shape with a first basic three-dimensional shape of a paint-finished wrinkle base, the coating finish is not damaged. You can get a bag that can. It is also the provision of new designs to the traditional lacquer ware industry with a limited degree of design freedom.
