Description

  The present invention relates to a stackable beverage container in which one set of an independent upper container and a lower container is connected and unified to be portable.

  A multi-stage bottle that can taste several different types of beverages is disclosed in Patent Document 1. The second embodiment described in FIG. 4 of Patent Document 1 is different from the first embodiment described in FIGS. It is considered to be a known technique.

Japanese Patent No. 6440190

  However, in each closed container (2a) (2b) (2c) of the multi-stage bottle (200) according to Example 2 of Patent Document 1, the small-diameter cylindrical portion (tap) (11) with the lid (1) escapes. Not only the concave part (6) at the center of the bottom part, but also an enlarged small-diameter cylindrical part (5) having an external thread (7), and extending from the neck part (30) of the concave part (6) to the maximum outer peripheral part (16B). Since the existing bottom funnel-shaped surface (29) also needs to be cut into three stages, that is, upper, middle, and lower, the height (height) of each of the closed containers (2a), (2b), and (2c) is reduced. If it is constant, the content will be significantly reduced. As a result, each of the closed containers (2a), (2b), and (2c) must be formed large (tall), which is unnecessarily bulky as a multi-stage bottle (200), which is inconvenient to carry.

  In addition, since the shape is cut in such a manner that the diameter decreases as going downward as a total of three stages of upper, middle, and lower, the peripheral portion (corner portion) of the inner bottom surface in each closed container (2a) (2b) (2c) ) Is sharpened as shown in the figure, and it is difficult to completely remove the components of the beverage settled at the corners, which causes discoloration and unsanitary feeling at an early stage.

  Further, the male screw (7) cut in the small-diameter cylindrical portion (5) of the lower container is screwed with the female screw (8) cut in the inner peripheral wall of the concave portion (6) in the upper container, and is turned. The multi-stage bottle of the second embodiment is different from that of the first embodiment in that a lid (1) is interposed between the upper and lower sides of both containers, and the lid (1) is tightened. When the male screw (7) and the female screw (8) are strongly tightened to the end, the bottom funnel-shaped surface (29) of the upper container and the shoulder funnel of the lower container are affected by the condition (degree of strength). As a result of the shape surface (9) not contacting the predetermined contact surface (40) with certainty or having contacted first, the male screw (7) and the female screw (8) are completely removed. Sometimes they can't be tightened too hard.

  Then, since the male screw (7) of the small-diameter cylindrical portion (5) and the female screw (8) of the corresponding concave portion (6) are screwed together, the upper container and the lower container are relatively left and right (horizontal). ), And is inferior in stability in a connected state (stacked state).

  In this regard, even if the space (21) serving as a tightening margin capable of increasing and tightening the male screw (7) and the female screw (8) is secured, there is no change, and rather a design difficulty is involved. In other words, considering that the closed containers (2a), (2b), and (2c) where the beverages remain in the consumer may be connected (stacked) again and used or carried, the space (21) There is no guarantee that securing) will always be helpful.

  The present invention aims to improve such a problem, and in order to achieve the object, in claim 1, the body has the same thickness as each other, and the upper end of the neck rising on the vertical center line of the body is drinkable. As a mouth, it consists of a set of a separate and independent upper container and lower container sealed by an opening / closing cap,

  At the center of the flat bottom surface of the upper container, a recess for the neck of the lower container, which is sealed with a spout, defines an indentation recess of the neck, and one ring-shaped rib is similarly directed downward from the peripheral edge of the bottom surface. While protruding,

  At the peripheral edge of the flat shoulder surface of the lower container, a ring-shaped rib receiving recess for receiving the rib of the upper container is formed correspondingly,

  The inner peripheral wall surface of the rib and the outer peripheral wall surface of the rib receiving recess are formed into a concave / convex curved surface having an S-shaped cross section or a sine waveform that can be fitted to each other,

  When the upper container and the lower container are relatively strongly pressed or pulled from above and below, the concave and convex curved surfaces are fitted and detachably fitted to each other to be connected.

  According to claim 2, a ring-shaped rib receiving recess is formed also on the peripheral edge of the flat shoulder surface of the upper container,

  In the central part of the flat bottom surface in the lower container, the escape recess of the neck is defined, and a ring-shaped rib is similarly projected downward from the peripheral edge of the bottom surface,

  The upper container and the lower container have the same shape, and are determined so that a connected state can be obtained without distinction between the upper and lower containers.

  On the other hand, in claim 3, the upper body and the lower vessel which have a body having the same thickness as each other, and the upper end of the neck standing on the vertical center line of the body serves as a drinking mouth, are separately independent upper and lower vessels sealed by an opening / closing cap. Consists of one set,

  In the center of the flat bottom surface of the upper container, the mouth of the lower container defines an escape recess of the sealed neck, and also distributes radially symmetrically as a whole from the periphery of the bottom surface. While projecting a plurality of arc-shaped ribs downward,

  On the peripheral edge of the flat shoulder surface of the lower container, a ring-shaped rib receiving recess for receiving all the ribs of the upper container is formed,

  The inner wall surface of each of the ribs and the outer peripheral wall surface of the rib receiving recess are formed into an S-shaped or sinusoidal concave and convex curved surface that can be fitted to each other,

  When the upper container and the lower container are relatively strongly pressed or pulled from above and below, the concave and convex curved surfaces are fitted and detachably fitted to each other to be connected.

  In claim 4, a ring-shaped rib receiving recess is formed also on the peripheral edge of the flat shoulder surface of the upper container,

  In the center of the flat bottom surface of the lower container, a recess for the neck is also defined, and a plurality of arc-shaped ribs that are distributed radially symmetrically as a whole from the peripheral edge of the bottom surface are also projected downward. By doing

  The upper container and the lower container have the same shape, and are determined so that a connected state can be obtained without distinction between the upper and lower containers.

  According to claim 5, the peripheral portion of the bottom surface of the upper container or the lower container where the rib protrudes is thickened.

  The peripheral edge of the shoulder surface on which the rib receiving recess is formed in the upper container or the lower container is made thinner than the peripheral edge of the bottom surface,

  When the ribs and the concave and convex curved surfaces of the rib receiving recesses are fitted to each other, the peripheral portion of the shoulder surface is set to be elastically deformed.

  Claim 6 is characterized in that the contents of the upper container and the contents of the lower container are the same, or the latter is set to be larger than the former.

  In the seventh aspect, the shrink wrapping label applied to the upper body and the lower body in a state of straddling both bodies is provided with a perforation for peeling along the vertical direction and a perforation for releasing connection along the circumferential direction. It is characterized by.

  Further, in claim 8, the beverage in the upper container is displayed above the perforation for releasing the connection in the shrink packaging label, while the beverage in the upper container is different from the beverage in the upper container below the perforation. Is displayed.

  According to the above configurations of claims 1 to 4, there is an effect that all problems of the multi-stage bottle described in Example 2 of Patent Document 1 can be easily improved.

  In other words, in the configuration of claim 1 and claim 3, the inner peripheral wall surface or the plurality of inner wall surfaces of the ring-shaped rib projecting downward from the largest diameter peripheral portion of the flat bottom surface in the upper container, and the flat shoulder in the lower container. The outer peripheral wall surface of the ring-shaped rib receiving recess formed so as to correspond to the peripheral portion having the largest diameter of the surface can be integrally connected in a stacked state by fitting the concave and convex curved surfaces having an S-shaped cross section or a sinusoidal waveform. Therefore, unlike the multi-stage bottle described in Patent Literature 1 in which a male screw of a small-diameter cylindrical portion and a female screw of a concave portion are screwed together, the left and right (horizontal) of the upper container and the lower container are different. ) A stable and solid stacking state (connected state) without the risk of swinging in the direction can be obtained.

  Moreover, the fitting and release of the concave and convex curved surfaces can be achieved only by relatively strongly pressing or pulling the upper container and the lower container from above and below, as in the multi-stage bottle described in Patent Document 1. In addition, there is no need to rotate the male screw on the lower container side and the female screw on the upper container side by screwing, and there is no opening / closing cap for the spout between the upper container and the lower container. It is not affected by the degree of screwing of the male screw and the female screw, the degree of tightening of the opening / closing cap, and the like, and a constant connection strength can always be obtained.

  Furthermore, it is sufficient if only the recessed recess of the neck where the drinking spout of the lower container is sealed is defined as an inverted U-shaped cross section at the center of the bottom surface of the upper container. As described above, there is no need to provide a total of three levels of cutout recesses that increase as going downward, and thus it is unnecessary to provide the closed container with a bottom surface, so that the contents may be unnecessarily reduced or the stacked state may be unnecessarily bulky. Nor.

  The above-mentioned various effects can be obtained from the constitutions of Claims 2 and 4, but if the constitutions of Claims 2 and 4 are particularly adopted, the upper container and the lower container are molded by one kind of mold which is common. Can help improve the mass production effect.

  Further, if the configuration of claim 5 is adopted, when the concave and convex curved surfaces having a S-shaped or sinusoidal cross section of the rib and the rib receiving recess are fitted to each other, the shoulder surface formed with the rib receiving recess is formed. By elastically deforming the peripheral edge portion, there is an effect that a smooth fitting action and a well-fitted and closely fitted state can be obtained.

  If the configuration of claim 6 is adopted, two different kinds of beverages can be carried with the same internal capacity, but there is an effect that the large-capacity lower container can stably support the small-capacity upper container.

  Furthermore, if the configuration of claim 7 is adopted, a series of shrink packaging labels straddling both the body of the upper container and the lower container makes it possible to impress the stacked beverage container as if it were a real one. Moreover, when the two containers are pulled from the vertical direction to release the connection, the shrink packaging label is naturally separated from the connection (separation) perforation, which is extremely convenient.

  In this case, if the structure of claim 8 is adopted, even if the shrink wrapping label is cut off from the perforation, the beverage name in the upper container corresponding to the upper container of the shrink wrapping label is displayed. Also, different beverage names in the lower container are displayed at the lower portion corresponding to the lower container, respectively, so that there is an effect of being able to identify them at a glance.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The stacked beverage container of the present invention is composed of a set of an upper container and a lower container which are independent from each other, and can be connected and integrated into a stacked state. However, the stacked beverage container according to the first embodiment shown in FIG. In the beverage container, the shapes of the upper container (A) and the lower container (B) are different.

  Therefore, the upper container (A) will be described first with reference to FIGS. 2 to 4. The upper container (A) has a substantially cylindrical body (container body) (10) having a constant thickness (for example, a diameter of about 65 mm) (D). , A continuous arcuate shoulder surface (11) at the upper part thereof and a horizontal flat bottom surface (12) at the lower part thereof, which are made of transparent or translucent polyethylene terephthalate (PET) resin or other preferably heat-resistant resin. Molding (blow molding) from a synthetic resin having a characteristic. The body (10) is provided with a concavo-convex pattern serving as a reinforcing rib, which is not shown.

  From the center of the torso (10), a thin neck (13) having a constant height (h) continuous with the shoulder surface (11) is positioned on the vertical center line (OO) of the torso (10). The upper end of the neck portion (13) is open as a drinking spout (14). (15) is an opening / closing cap for the spout (14), which is made of a desirably heat-resistant synthetic resin harder than the body (10) and has an inverted U-shaped cross section. It is detachably screwed and fastened. (D) shows the outer diameter of the neck portion (13) sealed by the opening / closing cap (15).

  However, the opening / closing cap (15) is not limited to the screwing and fastening means of the male screw (16) and the female screw (17) as shown in the figure, but can be turned up and down around a horizontal hinge (not shown) as a fulcrum. Therefore, even if the drinking spout (14) of the neck (13) is sealed, it may not be possible.

  On the other hand, an inverted U-shaped recess (18), which is depressed upward from the flat bottom surface (12) by a certain depth (g), is defined in the center of the body (10). The neck portion sealed by an opening / closing cap, which will be described later, can be smoothly inserted. (S) shows the inner diameter of the neck escape recess (18).

  In addition, one ring-shaped rib (19) protrudes downward from the periphery (the corner at the boundary with the body) of the flat bottom surface (12) of the body (10) by a constant height (y). Has been established. The ribs (19) also serve as grounding seats for stable and independent standing.

  Next, the lower container (B) will be described with reference to FIGS. 5 to 7. The lower container (B) has a body (container body) (20) having the same thickness (D) as the body (10) of the upper container (A), and It has the same height (h) as the neck (13) of the container (A) and a neck (23) of the same outer diameter (d) in which the spout (24) is sealed by the opening / closing cap (25). However, the shapes of the shoulder surface (21) and the bottom surface (22) of the body (20) are different from those of the upper container (A).

  That is, the shoulder surface (21) continuous with the upper portion of the substantially cylindrical body (20) in the lower container (B) forms a horizontal flat surface, and its peripheral portion (the corner portion between the body and the shoulder surface). Has a ring-shaped rib receiving recessed portion (30) corresponding to the ring-shaped rib (19) of the upper container (A), and has an L-shaped cross section which is lowered by a predetermined step (z).

  A ring-shaped rib (19) projecting downward from the periphery of the bottom surface (12) of the body (10) of the upper container (A) forms a shoulder surface (21) of the body (20) of the lower container (B). As shown in FIG. 1, the upper container (A) and the lower container (B) are connected to each other so as to be able to be freely fitted and detached into the ring-shaped rib receiving recess (30) formed corresponding to the peripheral portion of the upper container. It can be realized.

  In addition, the horizontal flat bottom surface (12) of the upper container (A) and the horizontal flat shoulder surface (21) of the lower container (B) are in a state of being in contact with each other from above and below. The contact between the upper container (A) and the lower container (B) can be prevented from tilting.

  Furthermore, as shown in the partially enlarged sectional view of FIG. 8, the inner peripheral wall surface (19a) of the ring-shaped rib (19) projecting downward by a certain height (y) from the bottom surface (12) of the upper container (A). ) And the outer peripheral wall surface (30a) of the ring-shaped rib receiving concave portion (30) which is lowered by a predetermined step (z) from the shoulder surface (21) of the lower container (B). It is shaped as an S-shaped or sinusoidal concave / convex curved surface, and the concave / convex curved surfaces (19a) (30a) are fitted together by receiving a pressing operation from above and below. It is set so that a certain fitting (biting) allowance (w) is fitted in one waveform of the S-shaped cross section or the sinusoidal waveform.

  In this case, as also suggested from FIG. 8, the peripheral portion of the upper container (A) where the rib (19) which can also function as a grounding seat of the bottom surface (12) is formed as a hard lump and a thick wall is formed. The peripheral edge of the shoulder surface (21), on which the rib receiving recess (30) of the lower container (B) for receiving the rib (19) is formed correspondingly, is formed with the rib (19). It is preferable to make the thickness substantially uniform so that it can be elastically deformed at the time of fitting.

  At the center of the bottom surface (22) of the body (20) of the lower container (B), a neck escape recess (18) having an inverted U-shaped cross section of the upper container (A) is defined. Absent. In this case, the bottom surface (22) of the lower container (B) forms a horizontal flat surface, and one ring-shaped rib (ground contact) (29) projects downward from the peripheral edge (boundary corner with the body). Although it is provided, the rib (grounding seat) (29) may not be provided, and the bottom surface (22) may be replaced with the horizontal flat surface, and a concave curved surface (conical surface) which is depressed upward and other lifts may be provided. Even if it is shaped to the bottom, it can be done.

  The lower container (B) is also integrally formed from the same synthetic resin as the upper container (A), and the opening / closing cap (25) of the spout (24) is also made of a male screw (26) and a female screw (27). The cap (25) is fastened to the neck (23) as long as the spout (24) can be opened and closed. Adopt it.

  FIG. 1 shows a stackable beverage container according to the first embodiment, which is composed of one set of the above-described upper container (A) and lower container (B), and includes an upper container (A) and a lower container (B). Is pressed relatively strongly from above and below, so that a ring-shaped rib (19) projecting downward from the periphery of the flat bottom surface (12) in the upper container (A) is flattened in the lower container (B). The rib (19) and the rib receiving recess (30) are inserted into a ring-shaped rib receiving recess (30) formed so as to correspond to the peripheral portion of the shoulder surface (21) so that the rib (19) can be freely inserted and removed. The concave and convex curved surfaces (19a) and (30a) having an S-shaped cross section or a sine waveform can be firmly and stably fitted to each other by a fixed fitting margin (w).

  At this time, the spout (24) of the lower container (B) is inserted into the inverted U-shaped neck escape recess (18) defined in the center of the bottom surface (12) of the upper container (A). The neck portion (23) sealed by the opening / closing cap (25) is naturally allowed to escape properly, and the upper container (A) and the lower container (B) are positioned on the vertical center line (OO). And concentrically connected to each other.

  The stacked beverage container is provided as a product in such a state for sale at stores, vending machines, and the like. For this purpose, the upper container (A) and the lower container (B), which form the beverage container, contain two different beverages, and the consumer who purchases them drinks the two beverages into bags or the like. Carry at the same time in the passenger seat, etc., and prepare to drink any desired beverage at any time.

  In this regard, in FIG. 1, lemon (fruit juice) is stored in the upper container (A) and black tea is stored in the lower container (B), but a combination of different beverages can be freely selected. In particular, two types of combinations that can be provided as hot (heated state) are preferable.

  In this case, the upper container (A) and the lower container (B) of the beverage container have bodies (10) and (20) having the same thickness (D), and are located on a vertical center line (OO) thereof. Are stacked in the same concentric connection state, the names (article names) of the beverages contained in the upper container (A) and the different beverages contained in the lower container (B) are displayed in a vertically sorted state in advance (printing) The product label (31) is shrink-wrapped so as to straddle both bodies (10) and (20) as shown in FIG.

  (32) is a perforation for disconnection (separation) provided as a horizontal state along the circumferential direction at the boundary between the upper container (A) and the lower container (B) in the shrink packaging label (31). The ribs on the bottom surface (12) of the upper container (A) can be obtained by the consumer pulling the upper container (A) and the lower container (B) of the beverage container relatively strongly from the vertical direction. (19) and the fitting state of the rib receiving recess (30) of the shoulder surface (21) of the lower container (B) is released, and the upper container (A) and the lower container (B) are separated. At that time, the shrink packaging label (31) is also separated from the perforation (32).

  The shrink packaging label (31) has not only a perforation (32) for separating (disconnecting) the upper container (A) and the lower container (B) but also a straight line along the vertical direction as shown in FIG. A perforation (33) for peeling (separate recycling) of the shape is also provided. It goes without saying that the perforations (33) are continuous between the upper container (A) and the lower container (B) in the shrink packaging label (31).

  The upper container (A) and the lower container (B), which form the above-mentioned beverage container, are not particularly limited in their contents. However, in view of stacking, both can be set to about 160 ml to 450 ml and set to the same contents as each other. desirable. When the content of the lower container (B) is changed differently, the content of the lower container (B) is set to be larger than that of the upper container (A), and the weight of the upper container (A) is reduced by the weight of the lower container (B). Is preferably maintained in a stacked state capable of supporting stably.

  Further, FIG. 9 shows a stacked beverage container according to a second embodiment of the present invention, in which the shapes and contents of the upper container (A1) and the lower container (A2), the spout, and the like. The overall configuration including the opening / closing caps is substantially the same as each other.

  Therefore, each of the upper container (A1) and the lower container (A2) will be described as a common single container with reference to FIGS. 10 to 12. This is the bottom surface of the upper container (A) in the beverage container of the first embodiment. (12) and the same configuration as the shoulder surface (21) of the lower container (B).

  That is, each of the upper container (A1) and the lower container (A2) has a substantially cylindrical body (container main body) (40) having a constant thickness (D) and a vertical center line (OO) from the center thereof. In order to seal the neck (43) standing up and the drinking spout (44) at the upper end thereof, the neck (43) is attached and detached to the neck (43) by means of a male screw (46) and a female screw (47). An opening / closing cap (45) freely fastened, of course, has a U-shaped recess (48) with an inverted U-shaped cross section at the center of the horizontal flat bottom surface (42) of the body (40). It is divided.

  The depth (g) and inner diameter (s) of the recess (48) are the same as those of the upper container (A) in the first embodiment, and the height of the neck (43) sealed by the opening / closing cap (45) is the same. As a dimension slightly larger than the height (h) and the outer diameter (d), there is a corresponding state in which the sealed neck (43) can escape.

  In addition, one ring-shaped rib (49), which can also function as a stable grounding seat, also has a constant downwardly extending height (from the periphery of the flat bottom surface (42) (boundary corner with the body)). y) only protruding.

  In addition, one ring-shaped rib receiving concave portion (50) corresponding to the rib (49) is provided on the peripheral edge portion (boundary corner portion with the fuselage) of the horizontal flat shoulder surface (41) in the body (40). ) Are provided in a substantially L-shaped cross section which is lowered by a predetermined step (z), and are in a state of being able to receive the rib (49).

  Since the upper container (A1) and the lower container (A2) have substantially the same configuration as described above, they are relatively strongly pressed from the upper and lower directions without discrimination between the upper and lower containers (A1). ), A rib (49) projecting downward from the periphery of the flat bottom surface (42) is fitted to the rib receiving recess (50) formed corresponding to the periphery of the flat shoulder surface (41) in the lower container (A2). ) Is also inserted and removed so that the inner peripheral wall surface (49a) of the rib (49) and the outer peripheral wall surface (50a) of the rib receiving recess (50) have an S-shaped or sinusoidal cross section. As a result, a stacked state in which the members are firmly and stably fitted with each other for a certain fitting (biting) allowance (w) as shown in FIG. 8 can be obtained.

  At the same time, the opening (44) of the lower container (A2) is opened and closed by the cap (44) into the inverted U-shaped neck escape recess (48) which is open at the center of the bottom surface (42) of the upper container (A1). The neck portion (43) in the state sealed by 45) can be naturally and accurately evacuated, so that the upper container (A1) and the lower container (A2) are as if they were one from the beginning. The concentric connection on the vertical center line (OO) is maintained.

  Other configurations of the beverage container according to the second embodiment of FIGS. 9 to 12 and configurations applied to the shrink packaging label (31) thereof are substantially the same as those of the first embodiment of FIGS. Since they are the same, only the corresponding reference numerals to those in FIGS. 1 to 8 are entered in FIGS. 9 to 12, and the detailed description thereof is omitted.

  In the stackable beverage containers according to the first and second embodiments, any of the stacked containers can function as a stable grounding seat from the periphery of the bottom surface (12) (42) in the upper containers (A) and (A1). The ribs (19) and (49) of FIG. 13 (y) are protruded downward as a single 360-degree ring shape, and are partially modified embodiments of FIGS. 13 and 14 corresponding to FIGS. As shown in the figure, the ribs (49) are also formed as a plurality (four in the illustrated example) of circular arcs distributed in a radially symmetrical arrangement form from the peripheral edge of the bottom surface (42). ) May be provided.

  However, in this case, the rib receiving recesses (50) of a constant step (z) formed corresponding to the peripheral portion of the shoulder surface (41) in the lower container (A2) can receive all of the plurality of ribs (49). As a ring shape, an S-shaped cross section of the outer peripheral wall surface (50a) or a concave / convex curved surface formed in a sinusoidal waveform, and an S-shaped cross section formed corresponding to the inner wall surface (49a) of each of the ribs (49) distributed in a dotted manner. The relationship between the concave and convex curved surface having a sine waveform is set so that the concave and convex curved surfaces can be fitted and removed by a pressing operation or a pulling operation from above and below.

  The plurality of ribs (49) distributed radially symmetrically as a whole as a whole protrudes downward from the periphery of the bottom surface (42) of the lower container (A2) so that the stacked beverage containers can be stably provided. It can serve as a grounding seat for self-reliance.

  13 and 14 illustrate a partially modified embodiment of the second embodiment, and other configurations in the partially modified embodiment are substantially the same as those of the second embodiment in FIGS. The configuration of the partially modified embodiment can be applied to the rib (19) of the upper container (A) according to the first embodiment.
