Description

  The present invention relates to a multi-stage bottle, and more particularly to a multi-stage bottle in which a plurality of independent containers can be connected in a multi-stage as a single bar.

  In conventional PET bottles, only one type of bottle can be tasted. Therefore, a conventional plastic bottle mainly used for beverages is multi-staged, and the independent containers that can be divided into multiple stages are connected in multiple stages to form a single structure. A multi-stage PET bottle is known in which a plurality of persons can simultaneously use different independent containers by releasing the connection (for example, Patent Document 1).

  In addition, a PET bottle structure that is convenient for provisional storage until disposal and that is planned to be reused from the beginning and a PET bottle connection structure in which a plurality of PET bottles are connected is known (for example, Patent Document 2). . Specifically, a bottom female screw is formed on the bottom of the plastic bottle body. The bottom female screw is threaded into the mouth male screw. On the other hand, a packing is provided on the bottom surface of the bottom female screw. By screwing the mouth male screw of another plastic bottle into this bottom female screw, two plastic bottles are connected in the vertical direction so that a plastic bottle connecting structure can be formed.

  In addition, there is known a container in which containers containing different contents are selected according to preference and the selected containers are connected to each other so that the contents can be mixed and drunk or the like ( For example, Patent Document 3). Specifically, an upper container having a lid member that can be incised on the bottom surface, a cut piece projecting outwardly on the bottom surface, and a male connecting portion formed on the outer peripheral surface of the bottom portion, and a ceiling surface These upper and lower containers are composed of a lower container having an incisable lid member and a cutout projecting outwardly on the ceiling surface and having a female connecting portion formed on the inner peripheral surface of the ceiling. In accordance with the operation of connecting the male and female type connecting portions to each other, both the lid members are incised by the other incision piece, and the contents of each other are mixed.

  In addition, a combination hermetically sealed container is configured such that a plurality of can-shaped sealed containers can be connected by providing a male screw on the lid of the sealed container shaped as a can and a female screw on the bottom. A container is known (for example, Patent Document 4).

  However, the multistage PET bottle of Patent Document 1 requires two types of PET bottles having different shapes for the upper stage and the lower stage. Therefore, separate molds are required for two different types of PET bottles, which is uneconomical.

  In addition, the one in Patent Document 2 is a PET bottle connection structure in which a plurality of PET bottles are connected so as to be convenient for storage for disposal, and has pursued ease of use in a period from when a beverage is sold until it is consumed. It is not a thing. In other words, the main purpose is to occupy a small area during temporary storage until the PET bottle that has finished its original role is discarded. Especially the thing of patent document 2 does not raise the added value and the convenience so that several kinds can be tasted by one by making a multi-stage PET bottle.

  In other words, it is not suitable for use in which a plurality of PET bottles filled with beverages such as juice are stored, distributed, and sold in a connected state, and carried by end consumers little by little. The reason is as shown in FIG. 4A of Patent Document 2 is a connection structure in which the strength for maintaining the rod-like structure of the connection body, particularly the strength in the bending direction, is decisively insufficient. This is because it will force considerable consideration to the person. Also, the ratio of length to volume is poor. In other words, the vessel is small for the bulky.

  Moreover, the thing of patent document 3 mixes the contents by mixing two different bottles which were separate at the time of sale at the time of drinking, and uses them for drinking. It is different from the direction of space saving at the time of storage or convenience at the time of carrying.

  Moreover, the combination sealed container of FIG. 7 of Patent Document 4 is superior to the multistage PET bottle of Patent Document 1 that requires two or more different shapes in that it can be unified into one shape. ing. However, in FIG. 7 of Patent Document 4, the male screw formed for the purpose of screwing the lid on the drinking mouth of the PET bottle is also used for fastening for multi-stage connection with another bottle combined in the upper stage. It is not a configuration.

  Therefore, it is similar to the multistage type PET bottle of Patent Document 1 in that a dedicated male / female screw portion for fastening two bottles in the upper and lower stages needs to be screwed to the peripheral portion. In this case, in particular, it may be difficult to screw a large-diameter female screw around the peripheral edge of a PET bottle having a single component configuration in terms of mold manufacture. In that case, it is necessary to prepare another material similar to the material of the cap, screw a large-diameter female screw close to the outer periphery of the bottle, and attach the other material to the peripheral portion of the bottle body. As a result, since the two-part structure is formed only by the part related to the structure and strength of the PET bottle main body, that is, the housing structure, a considerable increase in cost is inevitable.

  The present invention has been made in view of such problems, and the object of the present invention is to make it possible to compactly divide a large variety of liquids or powders into small parts by enabling a multi-stage connection of bottles mainly for beverages. Not only is it easy to store and transport by unifying, but also after the consumer obtains, several types of contents can be properly used by one, and each container has an independent structure.

It is a longitudinal cross-sectional view which shows the outline | summary of the multistage bottle which concerns on Example 1 of this invention. 2A and 2B are diagrams for explaining a connecting portion of the multistage bottle of FIG. 1. FIG. 2A is a schematic plan view, and FIG. 2B is a longitudinal sectional view. It is a perspective view which shows the outline | summary of the multistage bottle which concerns on Example 1 of this invention. It is a longitudinal cross-sectional view which shows the outline | summary of the multistage bottle which concerns on Example 2 of this invention.

Embodiments of the present invention will be described below with reference to the drawings. In addition, the same code | symbol is attached | subjected to the location and member, etc. of the same effect over all drawings, and description is abbreviate | omitted.
FIG. 1 is a longitudinal sectional view showing an outline of a multistage bottle according to Embodiment 1 of the present invention. As shown in FIG. 1, each of the multi-stage bottles 100 is a container having a structure in which sealed containers 10a, 10b, and 10c, which are PET bottles, aluminum bottles, steel containers, or glass containers, are vertically connected, that is, It is a multi-stage bottle with vertical connection. Each of the sealed containers 10a, 10b, and 10c has the same shape other than the heights H1, H2, and H3, and the outer appearance excluding the vicinity of the uppermost convex portion 22 when connected in multiple stages is a columnar shape.

  In FIG. 1, the shapes including the heights H1, H2, and H3 of the sealed containers 10a, 10b, and 10c connected in three stages are the same, but this is only an example, and H1 = H2 ≠ H3. H1 ≠ H2 = H3, H1 = H3 ≠ H2, or H1 ≠ H2 ≠ H3 may be used. Further, the number of connections is not limited to three, and may be two or more.

  Since this multi-stage bottle 100 has an independent structure for each hermetic container 10a, 10b, 10c, it is not only easy to store and transport a small number of various types of liquids or powders, but also to consume them. Even after the user obtains, several types of contents can be used properly by one connected in multiple stages. Conversely, one type of contents may be stored in a plurality of sealed containers 10a, 10b, 10c, and consumed while being opened sequentially.

  In addition, a label seal 26 (not shown in FIG. 1 and shown in FIGS. 2B and 3) that does not shift up and down across the connecting portion 25 of the sealed containers 10a, 10b, and 10c is attached. It has a function to prove that the subsequent sealed containers 10b and 10c are unopened. The label seal 26 is provided with a perforation 27 for facilitating cutting when the connection is released. That is, the consumer breaks the label seal 26 from the perforation 27 as appropriate to release the connection of the multistage bottle 100 and opens the second and subsequent sealed containers 10b and 10c.

Below, the detailed structure of the multistage bottle 100 is demonstrated.
That is, each of the sealed containers 10a, 10b, and 10c includes a small-diameter cylindrical portion 11 formed integrally with a substantially cylindrical main body, a male screw 12, a concave portion 13, a female screw 14, and a shoulder funnel-shaped surface 17. And a bottom funnel-shaped surface 18. In addition, when each of the sealed containers 10a, 10b, and 10c is a glass container, a material such as a resin, that is, a material that can easily be fitted into one of the male screw 12 and the female screw 14, that is, a screw of glass. Is preferably used.

  The small-diameter cylindrical portion 11 protrudes and opens in the vertical axis Y direction at the center of the upper portion of the cylindrical main body to form an entrance / exit of the container. When used as a beverage container, the small-diameter cylindrical portion 11 directly touches the consumer's lips. It becomes. A male screw 12 is formed on the outer periphery of the small-diameter cylindrical portion (hereinafter also referred to as “a drinking mouth”) 11. The lid 1 with the female screw 4 adapted to the male screw 12 of the drinking mouth 11 is screwed openably and closably, so that the drinking mouth 11 can be opened with the lid 1 even if the entire contents of the bottle cannot be swallowed at once. It can be closed and stored temporarily, and the lid 1 can be opened and re-drinked in a timely manner. Further, a seal portion 24 is also formed or disposed on the abutting surface 23 inside the lid 1. In the beverage PET bottle, the lid 1 is provided with a mechanism for proving the unopened state, but details thereof are omitted.

  The recess 13 has a size that can accommodate the small-diameter cylindrical portion 11 and is configured such that the center of the bottom is depressed in the Y-axis direction. A female screw 14 is formed on the inner peripheral wall of the recess 13. The female screw 14 can be screwed onto a male screw 12 formed on the outer periphery of the small diameter cylindrical portion 11. Therefore, a plurality of sealed containers 10a, 10b, and 10c are connected in multiple stages in an arbitrary order by screwing and fastening the male screw 12 of the other sealed containers 10b and 10c to the female screw 14 at the bottom of one sealed container 10a. Is possible.

  The shoulder funnel-shaped surface 17 has a shape common to the sealed containers 10a, 10b, and 10c, and extends from the base portion 15 of the small diameter cylindrical portion 11 to the maximum outer peripheral portion 16 (including 16A and 16B). Further, the bottom funnel-shaped surface 18 extends from the neck portion 19 of the recess 13 to the maximum outer peripheral portion 16B. The shoulder funnel-shaped surface 17 and the bottom funnel-shaped surface 18 are formed in an uneven shape such that the abutting surfaces 20 are closely fitted to each other.

  The multistage bottle 100 is configured to be connected in multistage by screwing the male screw 12 of another closed container 10b to the female screw 14 of one closed container 10a. When the multi-stage bottle 100 is connected in this manner, the contact surface 20 between the bottom funnel-shaped surface 18 of the sealed container 10a positioned on the upper side and the shoulder funnel-shaped surface 17 of the sealed container 10b positioned on the lower side. Are concentrically distributed in the vicinity of the maximum outer peripheral portion 16. Note that the contact surface 20 is not necessarily continuous in an annular shape, but may be symmetrical with respect to the center O of the maximum outer peripheral portion 16. For example, instead of the concentric contact surface 20, a plurality of contact surfaces divided from the center O in a sector shape divided by a radial slit pattern may be formed (not shown).

  That is, in addition to being configured in a concave and convex shape so that the contact surfaces 20 are closely fitted to each other, the connecting portion 25 is evenly supported in the circumferential direction in the vicinity of the maximum outer peripheral portion 16. High connection strength. In particular, it is easy to maintain rigidity against bending stress. As a result, the multi-stage bottle 100 can be handled as if it were a rod-like one, so that a large number of subdivided liquids or powders can be integrated into a single compact for easy storage and transportation.

  A seal portion 24 is formed or disposed on the abutting surface 23 of the concave portion 13, and the sealed container 10 b positioned below the seal portion 24 can be sealed when connected. In addition, since the internal shape of the recessed part 13 is the same as the inner side of the lid | cover 1, the same components as the seal part 24 arrange | positioned at the abutting surface 3 inside the lid | cover 1 are shared also in the abutting surface 23 of the recessed part 13. it can. Further, the abutting surface 23 of the concave portion 13 and the seal portion 24 may be integrally formed.

  FIG. 2 is a view for explaining a connecting portion 25 when the multi-stage bottle of FIG. 1 is connected to the female screw 14 of one sealed container 10a with the male screw 12 of another sealed container 10b and connected in a multi-stage manner. 2A is a schematic plan view, and FIG. 2B is a longitudinal sectional view. As shown in FIG. 2, in the connecting portion 25 of the multistage bottle 100, the area of the abutment surface 20 is a predetermined ratio (hereinafter referred to as “contact”) compared to the area M of the bottom funnel-shaped surface 18 or the shoulder funnel-shaped surface 17. (Also referred to as “rate”). This ratio A is preferably 50% or more and less than 100% as defined by the following formulas (1) to (4).

Area M = π (r ₄ ² −r ₁ ² ) of bottom funnel shaped surface 18 or shoulder funnel shaped surface 17
... (1)
Area S of contact surface 20 = π (r ₃ ² −r ₂ ² ) (2)
Adhesion rate A = S / M = (r ₃ ² −r ₂ ² ) / (r ₄ ² −r ₁ ² ) ≧ 0.5 = 50%
... (3)
50% ≦ adhesion rate A <100% (4)
In some cases, 10% ≦ adhesion ratio A <100% may be satisfied.

  In a state where the multi-stage bottle 100 is disconnected, the area S of the contact surface 20 is 0 and the adhesion rate A is 0%. When the male screw 12 of the lower sealed container 10b is screwed to the female screw 14 of the upper sealed container 10a to start multi-stage connection. When the male screw 12 is strongly tightened to the female screw 14 at the connecting portion 25, As the area S of the contact surface 20 increases, the adhesion rate A increases.

  However, the standard of the screw tightening strength is defined as an extent sufficient to seal the lower sealed container 10b. At this time, the space 21 shown in FIG. 2B needs to remain as an allowance for tightening the female screw 14 and the male screw 12. If this space 21 is not present, the adhesion rate A = 100%, but in that case, the female screw 14 and the male screw 12 cannot be tightened at the connecting portion 25, and the lower sealed container 10b can be sealed. It tends to be incomplete. The stroke of the additional tightening is absorbed by the elasticity of the seal portion 24 interposed between the abutting surface 23 of the recess 13 and the tip of the male screw 12.

  As shown in FIG. 2 (B), a label fixing groove perpendicular to the vertical axis Y is formed on each of the upper and lower outer circumferential surfaces straddling the connecting portion 25 so as not to shift vertically across the connecting portion 25 of the sealed containers 10a and 10b. It is preferable that the label fixing groove 28 is recessed and the label surfaces in the vicinity of the upper side and the lower side of the label seal 26 are bitten into the label fixing groove 28. The label seal 26 and the label fixing groove 28 are shown only in FIG. 2B, and are omitted in FIGS. The label seal 26 is provided with a perforation 27 for facilitating cutting when the connection is released. Although not shown in FIG. 2B, an equivalent label seal 26 is attached to the connecting portion 25 between the sealed containers 10b and 10c.

  FIG. 3 is a perspective view showing an outline of a multistage bottle according to Example 1 of the present invention (common to Example 2 described later). In addition, about the detail regarding this multistage bottle 100, especially about the location and member which attached | subjected the code | symbol in FIG. 3, it is as having already demonstrated using FIG. 1 and FIG. As shown in FIG. 3, the multi-stage bottle 100 has a clean and beautiful structure in order to give the impression that the figure connected in three stages is a single bottle.

  Further, the label sticker 26 shown in FIG. 2B is shown as a transparent film for the purpose of illustrating the state below the label sticker 26, but in practice, printing for clearly showing the contents is performed. In that case, it gives the impression that it is a single bottle. Then, the consumer selects and grasps any two of the sealed containers 10a, 10b, and 10c with the connecting portion 25 interposed therebetween, and twists and separates the fastened screws to separate them. For example, the consumer holds the middle sealed container 10a with the left hand, the lowermost sealed container 10c with the right hand, and loosens the screw so as to squeeze the wet towel, whereby the label seal 26 is broken at the perforation 27. At the same time, the connection of the connecting portion 25 starts to be released. As the operation proceeds, the lowermost sealed container 10c is opened, and the contents can be used for drinking. At the time of closing, the connecting portion 25 is connected again by an operation reverse to that at the time of opening. As a result, it is possible to return to a convenient shape for movement and storage as if it were one bottle.

  According to the present invention, a large number of subdivided liquids or powders can be integrated into a single compact to facilitate storage and transportation. Since each container has an independent structure, it is possible for multiple people to use different bottles at the same time, and which one to consume, which of the connecting stages to be divided, which Thus, it is possible to realize a multi-stage bottle with a lot of freedom including a part of play such as connection or replacement of connection stages.

  FIG. 4 is a longitudinal sectional view showing an outline of a multistage bottle according to Embodiment 2 of the present invention. In addition, it has already demonstrated in Example 1, Comprising: The same code | symbol is attached | subjected to the location and member, etc. of the same effect as what was shown in FIGS. 1-3, and description is abbreviate | omitted. 3 is common to the first and second embodiments, the label seal 26, the perforation 27, and the label fixing groove 28 shown in FIG. 3 are omitted from FIG. 4 as in FIG.

  The multistage bottle 200 shown in FIG. 4 can connect a plurality of sealed containers 2a, 2b, 2c vertically. Each of the sealed containers 2a, 2b, 2c includes a small-diameter cylindrical portion 11, 5, a male screw 12, 7, a recess 6, a female screw 8, a shoulder funnel-shaped surface 9, a bottom funnel-shaped surface 29, It is configured with.

  A male screw 12 is screwed to the small-diameter cylindrical portion (drinking mouth) 11, and a male screw 7 is screwed to the small-diameter cylindrical portion 5 whose diameter has been increased. The recess 6 has a size that can accommodate the small-diameter cylindrical portion 11 and the small-diameter cylindrical portion 5 that are covered with the lid 1 and is formed so that the center of the bottom portion is depressed in the Y-axis direction. The female screw 8 is screwed to the inner peripheral wall of the diameter-enlarged recess 6 so as to be screwed to the male screw 7. The shoulder funnel-shaped surface 9 extends from the base 31 of the enlarged small diameter cylindrical portion 5 to the maximum outer peripheral portion 16A. The bottom funnel-shaped surface 29 extends from the neck portion 30 of the recess 6 to the maximum outer peripheral portion 16B.

  Further, when the male screw 7 of the other sealed container 2b is screwed and connected to the female screw 8 of one sealed container 2a, the bottom funnel-shaped surface 29 of the sealed container 2a located on the upper side and the lower side are positioned. The contact surface 40 of the closed container 2b with the shoulder funnel-shaped surface 9 is distributed symmetrically with respect to the centers of the maximum outer peripheral portions 16A and 16B in the vicinity of the maximum outer peripheral portions 16A and 16B. The contact surface 40 is distributed concentrically with respect to the centers of the maximum outer peripheral portions 16A and 16B in the vicinity of the maximum outer peripheral portions 16A and 16B.

  The difference between the first embodiment and the second embodiment is whether or not a dedicated lid 1 is attached to each of the second to third sealed containers. That is, instead of having the dedicated lid 1 in the second to third sealed containers 10b and 10c of the first embodiment, the female screws 14 are respectively screwed in the recesses 13 of the upper sealed containers 10a and 10b. The inner wall and the abutting surface 23 function as the lid 1. Therefore, the sealed containers 10b and 10c are sealed in a state where they are connected in multiple stages.

  On the other hand, in the second embodiment, the second- and third-stage sealed containers 2b and 2c have their own lids 1 as in the first-stage sealed containers 2a, and are connected in multiple stages with the lids 1 closed. Can be decoupled. Therefore, a male screw 7 and a female screw 8 exclusively for connection are screwed to the sealed containers 2a, 2b, and 2c of the second embodiment regardless of the lid 1.

  A small-diameter cylindrical portion (a drinking mouth) 11 is extended with a small-diameter cylindrical portion 5 that is enlarged in steps on the base 31 side. A two-stage configuration in which the outer diameters of the small-diameter cylindrical portion 11 and the expanded small-diameter cylindrical portion 5 are different is employed. Further, a male screw 12 is screwed into the small diameter cylindrical portion 11, and a male screw 7 is screwed into the small diameter cylindrical portion 5 whose diameter is increased stepwise.

  Moreover, the recessed part 6 is provided in the bottom part of each airtight container 2a, 2b, 2c. In this recess 6, a small-diameter cylindrical portion 11 and a small-diameter cylindrical portion 5 having a two-stage configuration with different outer diameters can be accommodated while the lid 1 is further covered. In other words, the space corresponding to the thin small-diameter cylindrical portion (drinking mouth) 11 on the upper side is also secured as much as the thickness of the lid 1 with the drinking mouth 11 closed. A female screw 8 is screwed on the inner wall corresponding to the thicker small-diameter cylindrical portion 5 on the lower side. The female screw 8 is screwed with a male screw 7 screwed to the drinking mouth 11.

  In the multistage bottle 200 of the second embodiment, all of the sealed containers 2a, 2b, and 2c have a dedicated lid 1, and the multistage connection and disconnection are possible with the lid 1 closed, so that the sealed containers 2a, 2b, and 2c are closed. When one is divided into three persons, it is useful because the lid can be closed again without depending on other sealed containers.

  The present invention has been conventionally provided as a container with PET bottles and aluminum cans, that is, when providing beverages such as tea, coffee, tea, edible oil, seasonings and the like to consumers. There is a possibility of being used as a disposable bottle-shaped container. Moreover, it may be used not only for liquids such as beverages but also for storage, transportation, and provision to consumers of powdered seasonings, powdered milk, medicines, inks, and the like. In particular, when multiple types of seasonings and chemicals are required at the same time, for example, a combination of soy sauce and sauce, a combination of sweet, medium hot, dry sauce, a combination of oxidol and mercurochrome, etc. are suitable. It also has the effect of reducing careless mistakes.

  In addition, in seasonings, if the contents that deteriorate quickly with time, such as soy sauce, are subdivided and sealed, and then opened and consumed in sequence, the same volume can be consumed while being stored for a longer period of time. Furthermore, in the case of chemicals, multiple types are isolated and stored in separate containers until immediately before use. In addition to component-mixed chemicals that are used by mixing the various types at the time of use, storage such as when multiple types of drugs are used at the same time is stored. Further, when the multi-stage bottle 100 is applied for carrying, it is effective in terms of convenience, storage, economy, and prevention of careless mistakes. In particular, it is extremely useful for emergency medical treatment.

  In addition, there is a possibility that the wasteful provision method, which tends to be excessive due to a single bottle, can be improved to a more detailed and less wasteful provision method for beverages. In addition, multiple people can use different bottles at the same time, and include parts of play such as which to consume, which of the connecting stages to divide, how to connect, and selection of replacement of connecting stages. There is also a possibility that it can be improved to a provision method that has a lot of freedom and brings fun.

  In particular, for beverages sold by vending machines, there are restrictions on the types that can be handled by a single vending machine. This improves the functional efficiency of the equipment.
