Description

The present invention relates to a pouch container in which a synthetic resin pouring device is attached to a bag body.

In recent years, as a packaging body for fluid articles such as liquid beverages, shampoos, and jelly-like beverages, pouch containers in which a pouring device is attached to a bag having a laminated structure having a high gas barrier property are often used. In this pouch container, the dispensing device is composed of a main body welded to the bag body and a cap for closing the main body, and a screw lid is generally used as the cap.

On the other hand, long tubes and straws are attached to bottles and cup-shaped containers so that a person can suck them while placing the container at a remote location. Examples thereof are in Patent Documents 1 to 3. Have been described.

Microfilm of No. 51-100762 Microfilm of No. 51-139156 Microfilm of Jitsukaihei 03-090865

By the way, the containers provided with long tubes or straws such as Patent Documents 1 to 3 are bottles and cup-shaped containers, but if the bottles are made of resin, they can be slightly pressurized (squeezed) by hand, but basically. In the end, people inhale the contents, so it may be difficult for the elderly and people with weak physical strength to inhale.

In some cases, the tip of the tube or straw can be held in a part of the container, but since the tip of the tube or straw remains open, the contents may leak if the container collapses. There is a problem and there is a problem that it cannot be shipped with the tube and straw attached.

The invention of the present application has been made to improve such a situation.

The invention of the present application includes various configurations, and a typical configuration is specified in each claim. Of these, the invention of claim 1 is
"It has a bag and a pouring device attached to the top of it.
The pouring device comprises a flexible tube connected directly to the bag body or through a relay port, and an upper spout with an upper cap provided at the tip of the tube. "
It is configured as.

The invention of claim 2 is claimed in claim 1.
"The upper spout has an upward spouting cylinder and a tapered portion of an upward constriction provided at the lower end thereof, and an outward engaging protrusion is formed on the spouting cylinder.
The upper cap includes a top plate, a downward outer cylinder, and a downward inner cylinder that surrounds the dispenser cylinder, and the lower end of the outer cylinder abuts or is close to the tapered portion and is attached to the inner cylinder. When the inner cylinder is moved downward, an inward engaging portion that engages with the outward engaging protrusion is formed.
When the outer cylinder is pinched and squeezed and deformed from the direction intersecting the axial center, the lower end edge of the outer cylinder hits the tapered surface and moves upward, so that the inner cylinder is elastically deformed and the inward engaging protrusion is outward. It is set to disengage from the orientation engagement protrusion. "
It is configured as.

The invention of claim 3 is claimed in claim 1 or 2.
"While a relay port having a male screw is joined to the upper end of the bag body, a screw cap type lower cap screwed to the male screw of the relay port is provided integrally or separately at the lower end of the tube. ing"
It is configured as.

The invention of claim 4 is in any one of claims 1 to 3.
"The tube is at least partly bellows-shaped."
It is configured as.

In the present invention, since the tube is flexible, the bag body may be left on a table or the like and the tube may be bent downward to dispense the contents, or a sleeping person may include the tip of the tube in the mouth. Can be drunk. In this case, since the bag body can be manually pressed to pour out the contents, it is not necessary to tilt the bag body, and when a person drinks the contents, he / she can easily drink the contents even if he / she is weak. Therefore, it is user-friendly.

And since the upper spout at the tip of the tube is provided with an upper cap, it is safe because the contents do not leak even if the bag body falls down, and it can be distributed with the tube attached. .. In this respect as well, it is excellent in convenience and commerciality.

A screw lid or hinge cap can also be used as the cap for the upper spout, but if a type that opens by pinching operation as in claim 2 is adopted, it can be opened with one touch, which has the advantage of greatly improving convenience. There is. Furthermore, in the case of a screw lid or a hinge cap, it is troublesome to open the tube because the tip of the tube must be picked up with one hand and the cap must be rotated with the other hand. By adopting a method of pressing (pushing) the tube from the outside, the tube can be easily opened without having to firmly pinch the tip with one hand, which greatly improves convenience.

In the pouch container, the pouring device with a cap is usually of a screw cap type. Therefore, if claim 3 is adopted, the conventional pouch container can be used as it is, which is suitable.

If the tube is formed in a bellows shape as in claim 4, it can be bent greatly without difficulty, so that the contents can be poured into another container or a person can drink the contents by including the tip of the tube in the mouth. In, those actions can be performed very easily. Further, since the entire length or most of the product can be shortened and contracted in a bellows shape, distribution and storage can be facilitated and the commercial value can be further improved.

(1). Structure of First Embodiment Next, an embodiment of the present invention will be described with reference to the drawings. First, the first embodiment shown in FIGS. 1 and 2 will be described. The pouch container is composed of a bag body 1 formed by joining laminated films and a pouring device 2 attached to an upper end portion of the bag body 1. In the following, front-back and left-right words are used to specify the direction, but the wide-width direction of the bag 1 is defined as the left-right direction, and the direction orthogonal to the wide-width surface (thickness direction) is defined as the front-back direction.

The bag body 1 is formed in a quadrangular shape when viewed from the front, and the dispensing device 2 is attached to the left and right intermediate portions of the bag body 1. However, the mounting position of the dispensing device 2 can be arbitrarily set. The bag body 1 is composed of three films, a front and back film and a bottom film, and when the contents are filled, the bottom film spreads horizontally. Therefore, the pouch container of the present embodiment is a standing pouch that can stand on a flat surface such as a table.

The pouring device 2 includes a relay port 3 joined to the upper end of the bag 1 by welding, a tube 4 having a lower end connected to the relay port 3, and an upper spout 5 connected to the upper end of the tube 4. The upper spout 5 is opened and closed by the upper cap 6. All parts are made of synthetic resin.

The relay port 3 has a fixing portion 7 to which the bag body 1 is welded, and a cylindrical portion 8 exposed to the outside (upper side) of the bag body 1 into which the tube 4 is fitted, and is provided at the lower end of the cylindrical portion 8. While the upper flange 9 is provided, the lower flange 10 is provided at the upper end of the fixing portion 7, and the portion between the upper and lower flanges 9 and 10 is a guide cylinder portion 11 having a rectangular flat cross section.

As shown in FIG. 1 (E), the fixed portion 7 has an eyeball shape in a bottom view, and the upper and lower flanges 9 and 10 each have a slightly horizontally long octagonal shape in a plan view. The upper and lower flanges 9 and 10 are used in the filling process and the transportation process, and the pouch is formed by fitting a groove between the upper and lower flanges 9 and 10 into a pair of plate-shaped chutes (ribs) arranged in parallel. The container cannot be rotated and can be slidably held.

The lower end portion of the tube 4 is forcibly fitted to the cylindrical portion 8 of the relay port 3 from the outside. The cylindrical portion 8 is formed with a plurality of (or one step) annular projections 12 in order to prevent the cylindrical portion 8 from coming off. The tube 4 may be fixed to the cylindrical portion 8 by a fastener such as a band, or may be joined by welding. Alternatively, the tube 4 can be integrally molded with the relay port 3 by manufacturing using an injection blow device.

The upper spout 5 is continuous with the cylindrical joint portion 13 in which the upper end portion of the tube 4 is fitted from the outside, the octagonal flange 14 in a plan view integrally formed at the upper end portion of the joint portion 13, and the flange 14. It is composed of a tapered portion 15 with an upper constriction and a cylindrical dispensing cylinder 16 integrally formed at the upper end of the tapered portion 15, and an outward engaging protrusion having a chevron cross section is formed at the lower portion of the dispensing cylinder 16. An annular protrusion) 17 is formed. The joint portion 13 is formed with a plurality of steps (may be one step) of annular protrusions 18 for preventing the tube 4 from coming off.

On the other hand, the upper cap 6 is a cup-shaped basic form having a top plate 19 and an outer cylinder 20, the outer cylinder 20 has a tapered shape slightly downward, and the lower end edge is a tapered portion 15 of the upper spout 5. Abutment or proximity. Then, the inner cylinder 21 close to the outer peripheral surface of the dispensing cylinder 16 is hung from the top plate 15, and the inward engaging protrusion 22 that engages with the lower portion of the dispensing cylinder 16 is rotated around the lower end of the inner cylinder 21. It is formed so as to extend in a long direction. The engaging protrusion 22 is divided into four by a slit 23 that opens downward, and a recess 24 for visually recognizing the push portion is formed in a portion of the outer cylinder 18 located outside the slit 23. ..

The total length of the tube 4 is a bellows portion excluding the lower end portion fitted to the cylindrical portion 8 of the relay port 3 and the upper end portion fitted to the joint portion 13 of the upper spout port 5. Therefore, it can be bent and deformed in any direction and expanded and contracted. The bellows portion does not need to be formed over the entire length, and can be partially formed. For example, it can be formed at three locations: a portion closer to the relay port 3, a portion closer to the upper injection port 5, and an upper and lower middle portion. Further, the inner diameter of the tube 4 can be arbitrarily set.

(2). Summary of the first embodiment In the present embodiment, when the upper cap 6 is pressed by a finger, the lower end of the outer cylinder 20 hits the tapered portion 15 of the upper spout port 5, so that the upper cap 6 comes from the flange 14. The inner cylinder 21 is elastically deformed and the inward engaging projection 22 is detached from the outward engaging projection 17. Therefore, it can be opened in a watch-like manner by pushing.

When the contents are dispensed and then sealed, the joint portion 13 may be picked up with the fingertip of one hand and the inner cylinder 21 of the upper cap 6 may be pushed into the injection cylinder 16 of the upper injection outlet 5. Then, the lower end portion of the inner cylinder 21 is elastically deformed, and the inward engaging protrusion 22 engages with the outward engaging protrusion 17 to enter a sealed state. Therefore, the sealing can be performed with one touch, but since the fingertip holding the joint portion 13 hits the flange 14 from below, the fingertip does not slip and the sealing can be reliably performed.

The pouch container of this embodiment can be used in various ways. For example, as shown by a solid line in FIG. 2, the contents can be dispensed into a container 26 placed on a flat table 25 such as a table and also placed on the table 25. That is, by picking the upper injection port 5 with one hand and pointing it toward the container 26, and pressing the bag body 1 with the other hand, the contents can be dispensed without lifting the bag body 1.

Since the shape of the bag body 1 changes in the pouch container, in the case of a refillable pouch container, if the capacity is large, it may be difficult to hold and it may be troublesome to dispense (pour out) the contents. Since the contents can be poured out only by pressurizing the body 1 by hand, it is possible to dispense easily and accurately even if the capacity is large. The contents may be distributed in small amounts to a large number of containers, but in this case as well, the pouch container of the present embodiment is extremely useful because the pressure can be easily adjusted and even a small amount can be poured out with high accuracy.

As another example of use, as shown by the alternate long and short dash line, a person can ingest the contents by including the upper spout 5 in the mouth 27. For example, a pouch container can be placed on a table, and the person himself / herself can pressurize the bag 1 to ingest the contents. Alternatively, the upper spout 5 may be included in the mouth 27 of the person sleeping on the bed, and another person such as a caregiver may perform the pressurizing operation of the bag body 1. In any case, since it is not inhaled by the person himself / herself, even a person with weak physical strength and low vital capacity can easily take it. Therefore, it is also suitable for long-term care.

Instead of directly pressurizing the bag body 1 by hand, as shown by a two-dot chain line in FIG. 2, it is also possible to use a holder 28 having two side plates 28a sandwiching the bag body 1 from both the front and back sides. be. When the holder 28 is used in this way, the pressure can be strongly transmitted to the bag body 1, so that the pouring can be performed stably. It is preferable that the distance between the two side plates 28a is narrowed according to the weight reduction of the contents so that the contents can be squeezed out to the end.

The tube 4 bends and deforms due to its own weight and the weight of the upper spout 5, but it seems that the upper spout 5 floats in the air without completely collapsing in a free state where no external force is applied. It is preferable to set the strength so that it can be maintained in a state. As the contents decrease, the bag body 1 may be deformed. However, in the present embodiment, the upper spout 5 is closed by the upper cap 6, so that the tube 4 is bent and the upper cap 6 is a table or the like. Even if it hits, the upper spout 5 is kept in a clean state.

(3). Other Embodiments The second embodiment shown in FIGS. 3A to 3C is a modification of the first embodiment, and in addition to the configuration of the first embodiment, the tube 4 is in a contracted state. There is a locking means to hold it in. That is, in this embodiment, a lock plate 30 that can rotate up and down is integrally provided on a pair of long sides of the upper flange 9 in the relay port 3, and a square engaging hole 31 is formed at the tip of the lock plate 30. On the other hand, the tube 4 is provided with a plan-viewing mushroom-shaped engaging protrusion 32 on the flange 14 of the upper spout 5, and the engaging hole 31 of the lock plate 30 is fitted into the engaging protrusion 32 against elasticity. Is kept in a contracted state.

By holding the tube 4 in a contracted state in this way, it is possible to distribute the tube 4 in a state where the tube 4 is attached, and it is possible to improve the commercial value. A separate member may be used as the locking means, but if the locking plate 30 is integrally formed as in the embodiment, the structure can be simplified accordingly.

In the third embodiment shown in FIG. 3D, a male screw 34 is formed in the cylindrical portion 8 of the relay port 3, and a screw cap type lower cap 35 is screwed into the cylindrical portion 8 and mounted on the lower cap 35. The upward-facing cylinder 36 is integrally formed, and the tube 4 is fitted and attached to the cylinder 36.

Further, an engaging flange 37 for preventing disconnection is formed in the cylindrical portion 8, and outward ratchet claws 38 are interspersed between the engaging flange 37 and the upper flange 9 in the circumferential direction, while the lower An inward ratchet claw 39 that engages with the outward ratchet claw 38 is formed at the lower end of the cap 35, and the lower cap 35 is held irreversibly by engaging both the ratchet claws 38 and 39. The inward ratchet claw 39 engages the engaging flange 37 from below, so that the lower cap 35 is held upward and immovably.

In the fourth embodiment shown in FIG. 4A, the relay port 3 is basically the same as the first embodiment, and a screw-type upper cap 40 is attached to the upper spout 5 at the tip of the tube 4. There is. Upper and lower flanges 41 and 42 are formed on the upper spout 5 and a knob 43 for holding the upper spout 5 non-rotatably when the upper cap 40 is rotated is formed on the lower surface of the lower flange 42. A tubular body 44 for connecting the tube 4 is formed on the lower surface of the grip portion 43.

In the fourth embodiment, in the step of filling the contents, the relay port 3 is supported by the fitting of the upper and lower flanges 9 and 10 and the lower chute 45 so as to be slidable and non-rotatable, and the upper spout port 5 is supported. The upper and lower flanges 41 and 42 are fitted to the upper chute 46 so that they are slidable and non-rotatably supported. Therefore, filling can be performed accurately. Further, after filling, the tube 4 can be held in a contracted state by the lock plate 30. In this embodiment, the upper spout 5 is provided with a screw cap type upper cap 40, but a push type upper cap 6 as in the first embodiment can also be used.

4 (B) to 4 (D) show another example of the form of the bag body 1 and the arrangement position of the relay port 3. Of these, in the fifth embodiment of FIG. 4B, the upper portion of the bag body 1 is formed in a tapered shape with an upper constriction, and the relay port 3 is joined to the upper end portion thereof. On the other hand, in the sixth embodiment shown in FIG. 4C, one corner portion of the bag body 1 is cut diagonally, and the relay port 3 is connected to this corner portion. Further, in the seventh embodiment shown in FIG. 4D, the upper end of the bag 1 is formed diagonally, and the relay port 3 is attached to the upper end in a sideways posture.

Although the embodiments of the present invention have been described above, the present invention can be embodied in various ways.

The invention of the present application can be embodied in a pouch container. Therefore, it can be used industrially.
