JP6465478B2 - Pouch holding structure and spout and pouch as its components - Google Patents

Description

  The present invention provides a spout that contains contents to be discharged to an external space area and exhibits a coupling action with an annular collar portion of a pump mechanism for discharging contents, and a pouch comprising a flexible bag-like body attached to the spout. The present invention relates to a pouch holding structure that is held inside a hard and open / closed holder.

  In particular, the upper end side of the holder frame member in the pouch-accommodating state remains in the conventional narrow shape that is easy for the user to hold during the contents discharge operation, and the contents passing through the upper end side welded portion of the flexible bag-like main body are used. The spout of a cylindrical part is lengthened.

  The height of the spout is so high that the welded portion on the upper end side of the flexible bag-shaped main body, which cannot be accommodated and held at the upper end side of the narrow holder frame member, is wider than the upper end side of the holder frame member. The part can be accommodated and held without the bending work.

  That is, the upper end side welded portion of the flexible bag-shaped body is attached to the upper end portion of the holder frame member that is set narrower than the flexible bag-shaped body in consideration of the user's ease of gripping the holder during the content discharge operation This is an abandonment of the conventional concept of “accommodating”.

  The flexible bag-like main body is accommodated and held in a wide portion below the upper end portion of the narrow holder frame member in a state where the whole is shifted downward.

  The spout is set longer by the amount corresponding to the downward shift of the flexible bag-like body. The downwardly extending portion of the spout is accommodated inside the holder frame member as shown in FIG.

  The spout itself and the pouch itself as a component of such a pouch holding structure are also objects of the present invention.

  In this specification, regarding the width of the flexible bag-shaped main body and the holder frame member, the “reference width w1” of the upper end side welded portion of the flexible bag-shaped main body, the “narrow width w2” of the upper end portion of the holder frame member, and the holder frame member body Each word of “wide w3” is used.

  These “width” terms are the lengths in the left-right direction in FIGS. 1 and 2, that is, the holder frame member that can be opened and closed (in the case of illustration, the front-facing holder frame member into which the flexible bag-shaped main body is placed). The horizontal length is shown.

Here, “reference width w1” indicates the outer width (including the opening) of the upper end side welded portion of the flexible bag-like main body, and “narrow width w2” and “wide width w3” indicate the inner width of the holder frame member, respectively. Yes.
The length relationship between w1, w2, and w3 is substantially “w2 <w1 ≦ w3”.

  The conventional pump-type product (see FIG. 2) comprising the pouch 11, the holder 12, and the pump mechanism 13 has a width (inner width) w2 of the upper end portion of the holder frame member 12a for accommodating the flexible bag-like main body 11a. It is smaller than the reference width w1 (outer width) of the upper end side welded portion 11c of the main body.

That is, “w2 <w1” is set (see Patent Document 1).
The reference width w1 of the flexible bag-shaped main body 11a is a width when the pair of upper end side welded portions 11c formed on the left and right sides of the opening 11b are not bent.

  By setting the sizes of w1 and w2, the outer peripheral surface portion on the upper end side of the holder frame member 12a also acts positively as a gripping target portion of the user, and is designed in a holder frame member shape that is easy for the user to hold.

  On the other hand, the upper end side welded portion 11c of the flexible bag-shaped main body 11a having the reference width w1 wider than this must be placed in the upper end side internal space region of the holder frame member 12a having the size shape of the narrow width w2.

  In order to make this possible, the user bends each of the pair of upper end side welded portions 11c so that the substantial width becomes smaller than the narrow width w2 of the upper end portion of the holder frame member 12a as shown by the dotted line in FIG. It is deformed to.

  The pair of holder frame members 12a are closed in a state where the deformed flexible bag-shaped main body 11a is put in one of the insides. This closed state is held by a locking action portion 12c of a concave portion and a convex portion provided on the end portion in the vertical direction opposite to the hinge coupling portion 12b.

  A semicircular cutout portion for positioning and holding the spout 11d as the outflow side tubular portion of the closed flexible bag-shaped main body 11a is formed at the upper end portions of the pair of holder frame members 12a. Yes.

  The pump mechanism 13 is fixedly held on the spout by screw coupling between the annular collar portion 13a and the upper outer peripheral surface of the spout 11d.

JP 2000-191043 A

  As described above, in the case of the conventional pouch holding structure, in order to hold and store the flexible bag-shaped main body formed of the upper end side welded portion corresponding to the reference width w1 in the holder, the upper end side welded portion is bent and w2 or less. It was necessary to deform into a narrow state.

  As is clear from experience, the flexible bag-shaped main body is housed in an open holder frame member with its upper end side welded portion folded inward, and the pair of holder frame members are closed. Setting the state is a rather troublesome task.

  Therefore, in the present invention, the upper end side of the holder frame member in the pouch-accommodating state is set to the upper end side welding portion of the flexible bag-like main body while keeping the conventional narrow shape that is easy for the user to hold when the contents are released. The spout of the cylindrical part for passing contents is made longer.

  By this heightening of the spout, the welded portion on the upper end side of the flexible bag-like main body can be accommodated and held in the wide portion of the holder frame member body without the bending work.

  That is, the flexible bag-like main body is accommodated and held at a position shifted to the wide portion below the upper end portion of the narrow holder frame member. The spout is longer than the conventional one by this shift.

  Thus, while maintaining the simplicity and convenience of the user's contents discharge operation in the conventional pump-type product state, the flexible bag-like main body formed of the welded portion on the upper end side of the conventional reference width w1 is accommodated in the holder frame member. The purpose of this is to simplify and ensure the assembly work when holding.

  A pouch holding structure having such a configuration and spouts and pouches as its constituent elements are the subject of the present invention.

  The present invention solves the above-described problem solving means by replacing the conventional flexible bag-like main body formed of the upper end side welded portion of the reference width w1 with the holder frame member while maintaining the simplicity and convenience of the contents discharge operation in the conventional pump-type product. It is possible to simplify and ensure the assembling work to be housed and held in the housing.

Without changing the shape and size of the upper end side portions of the holder frame member and the flexible bag-shaped main body of the present invention, the pouch upper end side welded portion having the reference width w1 is connected to the wide width w3 (w3 ≧ w1) of the holder frame member.

Respectively.

The basic features of the illustrated pouch holding structure are:
(11) The upper end side shape of the holder frame member 4a in the pouch-accommodating state is set to the upper end side weld portion 3c of the flexible bag-shaped main body 3a while maintaining the conventional narrow width w2 that is easy for the user to hold when the contents are released. Lengthen the spout 3e of the tubular portion for passing the contents,
(12) That is, a lower cylindrical portion 3g is newly formed separately from the general-purpose upper cylindrical portion 3f that exhibits a screw coupling action with the annular collar portion 1c of the pump mechanism 1.
(13) Due to the height of the spout of the vertical drop H associated with the new installation of the lower cylindrical portion 3g, the upper end side welded portion 3c of the flexible bag-shaped main body 3a is made to be only H above the narrow width portion on the upper end side of the holder frame member. In the lower wide w3 portion, the upper end side welded portion can be accommodated and held without bending work.
That is.

The work procedure for attaching the new pouch 3 containing the contents shown in FIG.
(21) First, one side of the opposed peripheral surface portion 3b of the pouch 3 is engaged with one side of the holder frame member 4a in the open state, and the outward ring flange-shaped portion 3h is engaged with the circumferential concave portion 4c of the holder 4 Install with
(22) Next, the other of the holder frame members 4a is closed to engage the entire outer ring-shaped portion 3h and the circumferential concave portion 4c, and the holder frame members 4e are brought together by the lock action portion 4e. Set to locked state,
And so on.

  In the case of the pouch 3 at the stage where the pump mechanism 1 is not attached, a cap (not shown) for preventing the outflow of contents is attached to the outer peripheral screw surface of the upper cylindrical portion 3f in a screwed state.

  After the cap is removed, the annular collar portion 1c of the pump mechanism 1 is screwed onto the outer peripheral thread surface of the upper cylindrical portion 3f, so that it can act as a pump-type product for various uses.

  That is, when the trigger lever 1b of the pump type product in which the annular collar portion 1c of the pump mechanism 1 is attached to the upper cylindrical portion 3f of the pouch 3 is pulled to the right in the counterclockwise direction in FIG. The volume of the content storage space area between the suction valve and the suction valve is reduced.

  In addition, as the volume of the contents storage space area decreases, the internal pressure of the space area increases and shifts to the state of “suction valve: closed, discharge valve: open”, and the stored contents in the space area become holes. Released from the part 1a to the external space.

  When the user stops the content discharge operation of the trigger lever 1b, the trigger lever returns to the initial position before the operation by a known elastic action.

  With the return operation of the trigger lever 1b, the discharge valve is closed, the volume of the content storage space is increased, the internal pressure is reduced, and the suction valve that has been closed is shifted to the open state.

  Due to the reduction of the internal pressure and the shift of the suction valve to the open state, the contents stored in the flexible bag-shaped main body 3a flow into the content storage space area inside the pump mechanism via the spout 3e.

  The suction valve closes when the internal pressure of the content storage space increases to approximately the same as that of the flexible bag-shaped main body 3a due to the inflow of the content. The stored content when the suction valve is closed corresponds to the content to be released next time. The operation of the above pump mechanism is of course well known.

  When the contents stored in the pouch 3 are exhausted, the holder frame member 4a is opened after releasing the locking operation of the lock action portion 4e of the holder 4, and the used pouch is removed and replaced with a new pouch. That's fine.

Of course, the present invention is not limited to the illustrated embodiment.
(31) The wide width w3 of the upper end portion of the holder frame member 4a is set to be substantially the same width as the reference width w1 of the upper end side weld portion 3c of the flexible bag-shaped main body 3a.
(32) The cross-sectional shape of each outer peripheral surface of the upper cylindrical portion 3f or the lower cylindrical portion 3g of the spout 3e is set to a shape other than a circle such as an ellipse, an oval, a rectangle,
