Description

  The present invention relates to a packaging container that contains a liquid or the like, and more particularly to a self-supporting standing pouch container.

  In many cases, so-called standing pouch containers are used to wrap liquids or fluids such as seasonings such as soy sauce, and household items such as liquid detergents and softeners. The standing pouch container is formed by processing a resin film to widen the bottom and allowing it to stand on its own.

  Due to the feature of being able to stand on its own, producers can efficiently pack products on cardboard and transport them efficiently. The seller can display the product nicely at the store. Consumers can easily organize and store at home.

  By the way, the pouch container can be rounded and reduced in volume after use, and is often used for refilling from the viewpoint of resource saving. More attention has been paid to resource saving, and in recent years, it has been increasingly used as a container body.

  When a standing pouch container is used as a container body, if the contents are seasonings, liquid detergents, softeners, etc., the entire amount is rarely used at once, and only the necessary amount is poured out in a timely manner. At that time, it may be required to accurately measure and dispense the contents.

  As a standing pouch container having a weighing function, for example, a conventional technique described in Patent Document 1 has been proposed.

  The standing pouch container according to the prior art is provided with a bag portion that opens toward the spout in the inner space of the container, and in this bag portion, the contents in the container are temporarily stored and measured in a thin cup shape. Insert and place a scale.

  Tilt the container with the spout closed, pour the contents into the simple measuring instrument, measure it, and after confirming that it is a predetermined amount, open the container and pour out the contents in the simple measuring instrument.

JP 2005-029177 A

  The prior art has several problems as follows.

  The weighing function of the prior art is exhibited by tilting the container, and a weighing error occurs due to a delicate operation when the container is tilted.

  In particular, when the contents are large, there is a possibility that the simple measuring instrument may be entered more than intended and measurement may not be performed accurately. Moreover, even when it can measure accurately, the content outside a simple measuring instrument is also poured out at the time of dispensing, and as a result, there is a possibility that accurate measurement cannot be performed.

  On the other hand, when the contents are small, since the opening of the simple measuring instrument is at the top, it is difficult to incline the container and put the contents into the simple measuring instrument, and there is a possibility that the measurement itself cannot be performed.

  That is, although the standing pouch according to the conventional technique can be measured, there is a problem relating to accuracy of measurement.

  The present invention solves the above-described problems, and an object of the present invention is to provide a standing pouch container and a packaging container that can measure and dispense contents more accurately.

  In order to solve the above-mentioned problems, the present invention is a standing pouch container formed of a film, provided with a cap at a spout, and packaged in liquid or fluid content, and the container is provided with upper and lower parts when the container is self-supporting. A metering space provided so that the direction is the longitudinal direction and one end in the longitudinal direction communicating with the spout, a check valve provided at the other end in the longitudinal direction of the metering space, and passing through the check valve And a scale mechanism used for weighing the contents temporarily accommodated in the weighing space, wherein at least one surface of the film is transparent or translucent at a position corresponding to the weighing space. To do.

  By making the vertical direction of the standing pouch container the longitudinal direction of the measuring space, the height of the contents in the measuring space can be grasped as a quantity, and even a small amount of weighing can be accurately performed.

  In the state where the contents are filled in the standing pouch container, the water head pressure in the filling space (the space other than the measuring space in the standing pouch container) acts on the check valve. No object passes through the check valve and moves into the metering space. Further, when pressure is applied with a finger, the contents pass through the check valve and move from the filling space to the metering space. Referring to the scale, weigh the contents of the weighing space. The contents once accommodated in the measuring space are not returned to the filling space by the check valve.

  Tilt the standing pouch container and pour the contents. The contents stored in the weighing space are poured out. On the other hand, if there is a portion without the contents, the contents in the filling space will not move to the weighing space and will not be poured out.

  In this way, the contents can be weighed more accurately and only the weighed contents can be reliably poured out.

  In the above invention, preferably, the measuring space is formed by welding the films to each other at a location along the guide member and a guide member composed of two ship-shaped members and a connecting member that connects the ship-shaped members. And a separate seal portion to be formed.

  In the above invention, preferably, the measurement space is formed by a pipe member, and the pipe member is disposed along a transparent portion or a semi-transparent portion of the film. More preferably, the side of the pipe member along the film is transparent or translucent, and the opposite side of the side along the film is a different color from the contents and the side along the film.

  In the above invention, preferably, the measurement space is formed by a half pipe welded to the film along a transparent portion or a semi-transparent portion of the film.

  With these configurations, a measurement space is formed.

  In order to solve the above-mentioned problems, the present invention is formed by a film, wraps liquid or fluid contents, a cap provided at a spout, and a vertical direction when the container is self-supported in a longitudinal direction inside the container. And a guide member composed of two hulls and a connecting member for connecting the hulls to each other so that one end in the longitudinal direction communicates with the spout.

Standing pouch comprising a graduation mechanism used for weighing the contents to be stored and a transparent part or a translucent part provided at a position corresponding to the weighing space on at least one surface of the film When the outer edge of the container is welded, a separate seal part is formed by welding the films by welding from the outside of the container, and the guide member is formed in the space formed by the separate seal part. And the two ship-shaped members and the film are welded.

  By forming the separate seal portion at the same time as the outer edge seal portion, the forming step can be omitted by one step. Moreover, since it heats from the container exterior and welds films, construction is easy. Thus, a measurement space can be easily formed.

  Embodiments of the present invention will be described with reference to the drawings. 1 to 6 relate to the first embodiment, FIGS. 7 to 9 relate to the second embodiment, FIGS. 10 and 11 relate to the third embodiment, and FIG. 12 relates to the fourth embodiment.

<First Embodiment>
~Constitution~
FIG. 1 is an overall perspective view of a standing pouch container according to the first embodiment.

  A typical standing pouch container is composed of two opposing side films 11 and 12 and a bottom film 13, and is formed by welding the outer edges of the films to form the outer edge seal portion 14. For the films 11 to 13, a soft synthetic resin (for example, an olefin-based resin such as a linear polyethylene LLPE whose inner layer is laminated) is often used.

  By forming the bottom portion 13, the container shape becomes wider in the bottom direction, and the leg portions 15 are formed at the lower ends of the side films 11 and 12. As a result, the standing pouch container can stably stand on its own.

  A filling space 16 is formed inside the container. The filling space 16 is filled with a liquid or fluid (contents) such as seasonings such as soy sauce, and household items such as liquid detergents and softeners.

  The standing pouch container includes a spout 17 called a spout and a cap 18 provided at the spout 17. In FIG. 2, the cap 18 is a screw cap, but may be a hinge cap.

  The present embodiment includes a measurement space 20 as a characteristic configuration. The measuring space 20 has a longitudinal direction in the vertical direction when the container is self-supporting. One end in the longitudinal direction of the measuring space 20 communicates with the spout 17. By setting the vertical direction of the standing pouch container as the longitudinal direction of the measuring space 20, the height of the contents in the measuring space 20 can be grasped as a quantity, and a small amount can be accurately measured.

  A check valve 21 is provided at the other longitudinal end of the measuring space 20. The filling space 16 and the metering space 20 are continuous via the check valve 21. However, although the contents can move from the filling space 16 to the weighing space 20 via the check valve 21, the contents cannot move from the weighing space 20 to the filling space 16.

  The measuring space 20 and the filling space 16 are separated by a separate seal portion 22. The separate seal part 22 is formed by welding the films 11 and 12 by a predetermined length in the vertical direction.

  The separate seal portion 22 may be formed simultaneously with the seal portion 14. Thereby, one formation process can be omitted.

  A guide member 23 is disposed in the measurement space 20. The guide member 23 is composed of two ship shape members 24 and 25 and two connection members 26 and 27 for connecting the ship shape members to each other.

  FIG. 2 is an exploded perspective view of the guide member 23.

  The hulls 24 and 25 are hollow. The hull 24 is continuous with the spout 17. The hull 25 includes a check valve 21. The connecting members 26 and 27 define the length of the measuring space 20 in the longitudinal direction.

  For the hulls 24 and 25, for example, an olefin-based resin such as polyethylene PE is used, and the hull shape seal portions 28 and 29 (see FIG. 1) are formed by welding, and the hulls 24 and 25 are fixed to the films 11 and 12. Is done. The cross-sectional areas of the hull shapes 24 and 25 define the cross-sectional area of the measuring space 20. Thereby, the dimension and shape of the measurement space 20 are defined.

  Returning to FIG. 1, a product name, a product logo, and the like are generally printed on the films 11 and 12. Furthermore, in this embodiment, the transparent part 31 is formed in the location corresponding to the measurement space 20 of the film 11, and the scale 32 is printed on the transparent part 31. The transparent portion 31 may be translucent. Further, the portion other than the transparent portion 31 of the film 11 may be transparent.

  Note that the number of connecting members is not limited to two, and may be composed of one or a plurality.

~ Operation ~
An operation (usage example) of the standing pouch container of the present embodiment will be described.

  FIG. 3 shows an example of use when the contents are large.

  A large amount of contents are filled in the standing pouch container (FIG. 3A). In this state, the water head pressure in the filling space 16 acts on the check valve 21, but the content does not pass through the check valve 21 and move to the measuring space 20 only with the water head pressure in the filling space 16.

  The water head pressure here is a pressure due to the potential energy of the liquid, and the liquid is not limited to water. The contents are assumed to be condiments such as soy sauce, and household items such as liquid detergents and softeners.

  Furthermore, when a pressure is applied to the side films 11 and 12 with a finger, the contents move from the filling space 16 to the measuring space 20 through the check valve 21 according to the pressure and the operation time. With reference to the scale 32, it is confirmed whether a predetermined amount is accommodated in the measuring space 20, and when it is insufficient, pressure is further applied. When a predetermined amount is reached, the pressure action is stopped. Once the contents stored in the metering space 20 are not returned to the filling space 16 by the check valve 21. Weighing is performed according to such a procedure (FIG. 3B).

  The standing pouch container is tilted and the contents are poured out from the spout 17. The contents stored in the weighing space 20 are poured out. On the other hand, if no pressure is applied to the filling space 16 (if there is a portion having no contents), the contents of the filling space 16 will not move to the weighing space 20 and will not be poured out. In this way, only the weighed contents can be reliably poured out (FIG. 3 (c)).

  FIG. 4 shows an example of use when the content is small.

  A small amount of the contents are filled in the standing pouch container (FIG. 4A). In this state, even if pressure is applied to the side films 11 and 12 with a finger, the content may not move from the filling space 16 to the measuring space 20 due to insufficient head pressure.

  By the way, the films 11 to 13 are soft and can round the end of the standing pouch container. When the end of the standing pouch container is rounded, the cross-sectional area of the filling space 16 is reduced, the height of the contents is increased, and the water head pressure is also increased. In this state, when pressure is applied to the side films 11 and 12 with a finger, the content moves from the filling space 16 to the measurement space 20 through the check valve 21 according to the pressure and the operation time. Measure with reference to the scale 32 (FIG. 4B). The standing pouch container is tilted and the contents are poured out from the spout 17. (FIG. 4 (c)).

~effect~
The weighing function of the prior art is exhibited by tilting the container, and there is a problem that a weighing error occurs due to a delicate operation when the container is tilted.

  By the way, generally, a fingertip can perform a finer motion than a wrist or an elbow. In the prior art, the container is tilted by moving the wrist and elbow. The weighing function of the present embodiment is exhibited by applying pressure with a finger to a place where the contents of the filling space 16 are present. Thereby, it can measure more correctly compared with a prior art.

  Further, in the prior art, when there are a large amount of contents, there is a problem that the contents other than the weighed contents are poured out, and when the contents are a small amount, there is a problem that the weighing cannot be appropriately performed. In this embodiment, as described for the operation, it is possible to accurately measure whether the content is large or small.

  Another effect of this embodiment will be described. Generally, when the standing pouch container is tilted with the cap removed, the contents are washed away.

  FIG. 5 is an explanatory diagram when the standing pouch container of the present embodiment is tilted.

  Normally, if no pressure is applied to the filling space 16, the contents of the filling space 16 will not pass through the check valve 21 and move to the measuring space 20, and even if the standing pouch container falls down, the contents will be washed away. Never do.

  Even if the standing pouch container falls down at the time of weighing, the contents in the weighing space 20 may flow out, but the contents in the filling space 16 do not flow out, and the amount of loss can be suppressed.

  Another effect will be described. In general, when the contents are foods such as seasonings, once the cap is opened and the contents are exposed to the air, deterioration such as oxidation starts.

  In the standing pouch container of the present embodiment, even if the cap 18 is opened, the check valve 21 prevents the contents from coming into contact with the atmosphere, so that deterioration of the contents such as oxidation can be suppressed.

  Since the separate seal part 22 can be formed at the same time as the seal part 14, the formation process can be omitted by one process. Moreover, since it heats from the container exterior and welds the films 11 and 12, construction is easy.

~ Modification ~
The present invention is not limited to the above-described embodiment, and various modifications are possible within the scope of the technical idea of the present invention, as in the embodiments described later and modifications of the first embodiment. In the said embodiment, although the spout 17 is provided in the standing pouch container upper edge part, if it can pour out, it will not be limited to this.

  FIG. 6 is a perspective view of a modification of the first embodiment. The spout 17 may be provided on the upper side edge (FIG. 6A). An inclined portion may be provided at one corner of the upper edge portion and the side edge portion, and the spout 17 may be provided at this inclined portion (FIG. 6B).

  The transparent portion 31 and the scale 32 are formed only on the film 11, but may be formed on the film 12 (not shown). This makes it possible to measure regardless of whether you are right-handed or left-handed.

Second Embodiment
~Constitution~
In the first embodiment, the measurement space 20 is formed by the separate seal portion 22 and the guide member 23, but other configurations may be used as long as the dimensions and shape of the measurement space 20 can be defined. In the second embodiment, the measurement space 20 is formed by the pipe member 41.

  7 is an overall perspective view of a standing pouch container according to the second embodiment, FIG. 8 is an exploded perspective view of the pipe member 41, and FIG. 9 is a schematic cross-sectional view.

  One end of the pipe material 41 is continuous with the spout 17 via a hollow boat-shaped material 42. The other end of the pipe material 41 contains the check valve 21. The cross-sectional area and length of the pipe member 41 define the size and shape of the measuring space 20.

  The hull shape material 42 is welded to the film 11 by the hull shape material seal portion 43. Thereby, the pipe member 41 is disposed along the transparent portion 31.

  The side (front side) of the pipe member 41 along the transparent portion 31 of the film 11 is transparent (or translucent), and the opposite side (back side) of the side of the film 11 along the transparent portion 31 is along the contents and the film. The color is different from the side. For example, when the content is black soy sauce, white is colored. Since it has a transparent portion, for example, an olefin resin such as polyethylene PE is used for the pipe material 41.

  Here, for convenience of explanation, the above is called a two-color structure, but the two-color structure is not limited to colorless (transparent or translucent) and colored, but transparent (front), translucent (back), and transparent (front). And the combination of opacity (back).

~effect~
The second embodiment also has the same weighing function as the first embodiment and can accurately measure. Moreover, it has the other effect of 1st Embodiment.

  If the pipe material 41 is completely transparent, it may be difficult to distinguish the contents in the measurement space 20 and the contents in the filling space 16. By making the back side a color different from the contents, it is easy to distinguish the contents in the weighing space 20 from the contents in the filling space 16, and the weighing can be performed accurately.

  Moreover, since the ship-shaped material 42 and the film 11 are welded by heating from the outside of the container, the construction is easy.

~ Modification ~
The scale 32 is printed on the transparent portion 31, but may be printed on the pipe member 41.

  The pipe material 41 has a two-color structure (colorless and colored), but may be a one-color structure composed of a translucent color as long as the contents in the measuring space 20 and the contents in the filling space 16 can be distinguished. .

<Third Embodiment>
~Constitution~
FIG. 10 is an overall perspective view of the standing pouch container according to the third embodiment and an exploded perspective view of the Ω-shaped pipe member 51, and FIG. 11 is a schematic sectional view. In the second embodiment, the measuring space 20 is formed by the pipe member 41, whereas in the third embodiment, the measuring space 20 is formed by the Ω-shaped pipe member 51.

  While the pipe member 41 has a substantially circular cross section, the Ω-shaped pipe member 51 is formed in a Ω-shaped cross section. The Ω character is composed of a half pipe part and an Ω character leg part.

  One end of the half pipe portion of the Ω-shaped pipe member 51 is continuous with the spout 17 via a hollow boat-shaped member 52. The other end of the half pipe portion of the Ω-shaped pipe member 51 contains the check valve 21. The cross-sectional area and length of the half pipe portion of the Ω-shaped pipe member 51 define the size and shape of the measuring space 20.

  The hull 52 is welded to the films 11 and 12 by the hull seal 53. The Ω-shaped leg portion of the Ω-shaped pipe member 51 is welded to the film 11 by the Ω-shaped pipe member seal portion 54. Thus, the Ω-shaped pipe member 51 is disposed along the transparent portion 31, and a space 20 surrounded by the half pipe portion of the Ω-shaped pipe member 51 and the transparent portion 31 of the film 11 is formed. For the Ω-shaped pipe member 51, for example, an olefin resin such as polyethylene PE is used.

  The scale 32 is printed on the transparent portion 31, but may be printed on the Ω-shaped pipe member 51.

~effect~
The third embodiment also has the same weighing function as the first and second embodiments, and can accurately measure. Moreover, it has the other effect of 1st, 2 embodiment.

  The pipe material 41 has a two-color structure, whereas the Ω-shaped pipe member 51 has an arbitrary one-color structure. However, the color is preferably different from the contents. Thereby, manufacturing cost can be reduced.

  Moreover, since the ship-shaped material 52 and the films 11 and 12 are welded by heating from the outside of the container and the Ω-shaped pipe member 51 and the film 11 are welded, the construction is easy.

~ Modification ~
The Ω-shaped pipe member 51 of the present embodiment is an example of a half pipe member. There may be a half pipe member which does not have an Ω-shaped leg portion and is composed of a half pipe portion. Moreover, although the cross-sectional shape of a half pipe is made into semicircle as an example, if a part is open | released and a cross section can be welded to a film, a semi-elliptical shape, a triangular shape, a rectangular shape, etc. may be sufficient.

<Fourth embodiment>
In the first to third embodiments, the weighing function of the present invention is applied to a standing pouch container. In the fourth embodiment, the weighing function of the present invention is applied to a packaging container that is not a standing pouch container.

  FIG. 12 is an overall perspective view of the packaging container according to the fourth embodiment. The standing pouch containers of the first to third embodiments have the bottom portion 13 and the leg portions 15, whereas the packaging container of the fourth embodiment is provided with an outer edge seal portion 14 at the lower portion. Therefore, it cannot stand on its own, but other configurations are the same as the standing pouch container, and the function as the container is also the same.

  Furthermore, all the characteristic configurations described in the first to third embodiments can be applied to a packaging container.
