Description

  The present invention relates to a spout that is welded to an opening of a pouch (bag) filled with food, detergent, etc. to form a pouring path for contents, and more specifically, a pouch equipped with the spout. The present invention relates to a spout that is excellent in sealing performance and that can be easily opened, has a mischief prevention effect and a mischief clarification function, and a pouch equipped with the spout.

  Conventionally, a spout having a pour tube is attached to a pouch in which the peripheral portions of two rectangular flexible sheets obtained by laminating synthetic resin or metal foil or both are mutually heat-sealed, and a cap is placed on the spout opening of the spout The container which gave is used. This pouch with a spout is a method of guaranteeing a sealed state in the pouch by closing the spout by heat-sealing an inner seal having a picking part for peeling off at the opening end of a spout cylinder formed above the spout Is generally adopted.

  This type of pouch with a spout can ensure sufficient sealing performance as compared with the one that opens and closes the spout with caps such as screw caps, so when filling contents that particularly require retort sterilization treatment, Often used.

  However, in the pouch with a spout that employs an inner seal, there is almost no gap between the cap and the spout pipe of the spout. It is difficult to pick because the part is pressed against the outer peripheral surface of the dispensing cylinder by the cap, and the knob is folded between the opening end and the cap and fused to the outer peripheral surface of the dispensing cylinder. In any case, when the consumer peels off the inner seal and uses the contents, the peeling may not be easily performed.

In order to solve such a problem, Patent Document 1 discloses that a screw thread of a spout-side male screw into which a screw cap is screwed is made higher than usual, and a gap is formed between the screw cap to be screwed and the screw thread. Proposing a pouch with a spout that prevents the knob part of the inner seal from being pressed against the outer peripheral surface of the dispensing cylinder when the cap is attached, so that the inner seal can be peeled off easily by opening the knob. Has been.

  However, when a gap is formed between the spout pipe and the screw cap, the engagement between the screw cap and the screw pipe at the thread is weak, which causes a problem in sealing performance. In the first place, the inner seal attaches the inner seal to the opening end of the dispensing cylinder by heat sealing means, which is disadvantageous in terms of cost because the manufacturing process increases.

  The present invention was made to solve the problems associated with pouches equipped with spouts, and reduces the manufacturing cost, provides the container with necessary and sufficient sealing properties, and has tamper-evidence safety. The object is to provide a spout with high performance and a pouch equipped with the spout.

  The present invention for achieving the above-described objects includes a pour tube that pours out the contents in the pouch, and a mounting portion that is connected to the pour tube and is welded and fixed to the inner edge of the pouch. And a spout provided with a sealing bottom and a knob at the lower end of the dispensing cylinder, and a breakable weakening is formed on the dispensing cylinder located above the sealing bottom. The spout is characterized in that the knob piece and the attachment portion are connected by a connection piece.

  In the present invention, the pick piece provided at the lower end of the dispensing tube may be a thin flat plate shape so that it can be easily picked from the outside of the pouch, and the shape of the side surface thereof is rectangular, elliptical, trapezoidal. Any shape can be adopted. Moreover, it is preferable that the width | variety of a knob | pick piece shall be the dimension substantially the same as the width | variety of an attaching part from a viewpoint of the ease of picking. The breakable weakened part formed in the dispensing cylinder is made thin by making an annular cut groove on the outer or inner circumferential surface of the dispensing cylinder, and this part can be easily broken by a slight breaking force. What is necessary is just to form it. Further, it is desirable that the pouch is formed with a transparent or translucent region so as to be aligned with at least the lower portion of the spout including the weakened portion and the knob.

  In the present invention, a sealing bottom and a knob are formed at the lower end of the pouring cylinder without using an inner seal that is difficult to peel off the opening of the pouring cylinder, and the pouring located at the upper part of the sealing bottom. By forming a weakened part that can be broken in the exit tube, the sealing performance can be reliably maintained until it is opened, and at the time of opening, the handle is gripped, and a breakage force is applied to the weakened part to separate it. An opening is easily formed. In addition, if the weakened portion and the position of the pick piece can be visually confirmed by the transparent or semi-transparent region provided in the pouch, opening in use can be performed more reliably and easily, and further picking can be performed. Since the state of the piece is visible, the effect of suppressing mischief and the effect of clearly showing mischief are excellent. Further, in the present invention, since a spout with a bottom is used for the spout, there is no need to provide an inner seal on the opening, and therefore a heat sealing process is not provided in the filling process of the contents. Therefore, there is an effect of reducing the manufacturing cost.

  Furthermore, in the present invention, the knob provided at the lower end of the dispensing cylinder is formed into a thin flat plate shape, so that the knob is inserted when the spout attachment is inserted into the upper edge of the pouch and welded during product manufacture. It can serve as a guide for use, and the spout can be easily inserted into the pouch.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view showing an outline of a spout of the present invention and a pouch equipped with the spout. In the figure, 1 is a spout and 2 is a pouch. In this figure, the spout 1 is shown in a perspective view for convenience, and the pouch 2 is shown by a one-dot chain line. The spout 1 is provided with an extraction tube 3 extending in the vertical direction inside and outside the pouch having an opening 4 at the upper end and a sealing bottom 5 at the lower end. Reference numeral 6 denotes an attachment portion formed so as to be connected to the extraction tube 3 in order to weld and attach the spout 1 to the inner edge of the pouch 2. The attachment portion 6 is provided so as to be orthogonal to the axial direction of the dispensing cylinder, and in the present embodiment, the plane is formed in a substantially rhombus shape, but an elliptical shape or the like is formed on the inner edge of the pouch 2. The shape is not particularly limited as long as it is convenient for welding and fixing. Reference numeral 7 denotes a welded portion provided on the side surface of the attachment portion 6. Reference numeral 8 denotes a weakened portion formed in the dispensing cylinder above the sealing bottom 5. The weakening portion 8 is a breakable thin portion formed to separate the sealing bottom portion 5 from the dispensing cylinder 3 and form an opening, and is formed in an annular shape over the entire circumference of the dispensing cylinder 3. .

  Reference numeral 9 denotes a thin flat plate-shaped tab formed in connection with the sealing bottom. When the spout 1 is welded and fixed to the pouch 2, the picking surface of the picking piece 9 is the same or substantially the same as the inner surface of the pouch 2, and the width (the length in the direction of the upper edge 2a) is The width of the mounting portion (the length of the upper edge 2a) is substantially the same. The knob piece 9 is connected to the mounting portion 6 by a connecting piece 10. Reference numeral 11 denotes a cap attached to the opening 4 of the dispensing cylinder 3. In this embodiment, the cap 11 is screwed into a male screw 12 provided on the outer periphery of the dispensing cylinder 3. For example, known means such as a latching system in which an annular latching projection on the outer peripheral surface of the dispensing cylinder is provided and a latching projection is provided at an appropriate location on the inner surface of the cap to latch the two together can be employed.

  In order to attach the spout 1 to the pouch 2, the upper edge of the two opposing flexible sheets and the side edge excluding the lower edge are preliminarily welded and sealed by heat sealing. The spout 1 is inserted into the inner surface of the edge, and then the upper edge is welded and sealed together with the welded portion 7 by heat sealing. When the spout 1 is inserted into the pouch 2, the knob 9 serves as a guide, so that smooth insertion is performed. Then, after filling desired contents such as fluid food from the lower edge opening of the pouch, the lower edge is welded and sealed. The pouch 2 is generally made of synthetic resin, metal foil, or an opaque flexible sheet in which these are laminated, but as shown by a chain line 13 in the figure, the weakened portion of the spout 1 in the dispensing cylinder 3 The area | region matched with the insertion part of 8 and the pick piece 9 is made into transparent or semi-transparent.

  When the contents are poured out, the tab 9 of the spout 1 is picked from above the pouch 2, and then the weakening portion 8 is broken by applying a breaking force, the cap 11 is removed, and the contents are poured out. At this time, the pouch 2 is formed with a transparent or translucent region so as to align with the weakened portion 8 and the knob 9, so that the operation of the knob 9 and the tearing of the weakened portion 8 can be easily confirmed visually. can do. Since the cut piece including the knob piece 9 is connected to the attachment portion 6 by the connecting piece 10, there is no possibility that the pour opening will be blocked by floating inside the pouch 2.

It is a perspective view which shows one Example of the spout of this invention.
