Bouch-attached base and method for extracting fluid

Technical field

The present invention relates to a die attached to a resin film bag (bouch) in which a slurry-like fluid is accommodated and sealed, and more particularly, to a vouch having a simple mechanism and excellent operability. The present invention relates to a formula base and a method for extracting a fluid using the base. Further, the present invention relates to a voucher-attached base excellent in sanitation that can be applied to a voucher in which a liquid food product such as a cream jam is stored.

Background art

[0002] In various fields such as foods, medicines, and cosmetics, a device called a hopper is usually used to extract a predetermined amount of slurry-like products (contents). The hopper has an accommodating portion for accommodating the contents, and the outlet of the accommodating portion is provided with an extraction mechanism for extracting the contents by a predetermined amount.

[0003] Usually, the contents are sealed and accommodated in a resin film bag (bouch)! Then, the contents of the bag of the bouch are also transferred to the storage portion of the hopper and extracted by a predetermined amount by the extraction mechanism. However, with this method, it was necessary to clean the entire hopper when the type of contents changed or during regular maintenance.

Therefore, a voucher-attached base that can directly extract the contents without using a hopper has been proposed (for example, see Patent Documents 1 and 2).

Problems to be solved by the invention

[0005] In each of the above-described voucher-attached bases, the base is attached to the voucher using a double-sided tape. The double-sided tape usually has low adhesion to a surface where dust and moisture are present. For example, if the contents of a notch are refrigerated, removing the voucher from the refrigerator and keeping it at room temperature will cause water droplets to adhere to the surface of the bag skin. Surface with such water droplets attached In this case, the adhesive strength of the double-sided tape becomes weak, and the base cannot be securely attached to the voucher. Also, if an organic adhesive is used as the adhesive for the double-sided tape, it is not safe if the contents are foodstuffs.

[0006] The present invention has been made in view of the above problems, and has as its object to provide a vouch-attached base having a simple mechanism and excellent operability, and a method for extracting a fluid.

Means for solving the problem

[0007] The voucher-attached base of the present invention is attached to the outer surface of a resin film bag (bouch) in which a fluid (the contents) is packed and sealed. A base having a flange-shaped base applied to the outer surface of the vouch and a cylindrical mouth extending from the base; and a base of the vouch covered with the base applied to the base. And fixing means for pulling in and fixing the inner concave portion. In the present invention, it is preferable to further include a perforating means for perforating the bag bag that has been pulled in.

[0008] It is possible to draw and fix the sack of the knuckle into the base without using a double-sided tape or an adhesive. At this time, since the bag skin is fixed to the base by mechanical means, even when water droplets adhere to the surface of the bag skin, the base can be attached without much influence.

[0009] In the method for extracting a fluid according to the present invention, the fluid is extracted from a die attached to an outer surface of a resin film bag (bouch) sealed with a fluid (content) packed therein. A method in which the base is applied to the outer surface of the vouch, the bag skin of the portion to which the base is applied is drawn into the base and fixed, and a hole is formed in the drawn bag skin. The bouch force also extracts fluid through the holes.

[0010] Without using a double-sided tape or an adhesive, a cap can be attached to the bag skin to extract the contents. For this reason, the base can be attached without being affected by the surface condition of the bag skin, and the contents of the vouch can be extracted hygienically.

[0011] The voucher-attached base according to a specific embodiment of the present invention is attached to the outer surface of a resin film bag (bouch) in which a fluid (contents) is packed and sealed. A base serving as an outlet for a body, a flange-shaped base applied to an outer surface of the voucher And a main body having a cylindrical mouth extending from the base, and a bag skin of a voucher at a portion to which the base is applied is drawn into an inner recess formed in the base communicating with an inner hole of the mouth. A fixing means for fixing, wherein the fixing means has a needle-like tip, and can be fitted and accommodated in an inner concave portion of the main body base in a compressed state, and the base is connected to the main body. And a rim formed rotatably mounted on the base of the main body and pressed against the side of the element wire of the coil spring during rotation so as to press the coil spring into the inner recess. After the coil spring is inserted into the bag of the voucher in a state where the coil spring is extended out of the inner concave portion, the dial and the main body are relatively opposed to each other. Before rotating The coil spring is housed in the inner concave portion, and at this time, the bag skin is inserted so as to be sandwiched between the outer periphery of the coil spring and the inner surface of the inner concave portion.

[0012] This base is mainly composed of three parts, a main body, a coil spring, and a dial, and the number of parts is small. If these parts are made of a polycarbonate resin or the like that is safe for food hygiene, it can be applied to a voucher containing food and chemicals. In addition, the parts can be connected by mechanical means without the use of hygienic hazardous adhesives.

In addition, the operation consists of two operations: the operation of attaching the base to the voucher, the operation of inserting the coil spring into the vouch, and the operation of rotating the dial with respect to the main body and housing the coil spring in the main body. The base can be attached by simple operation. After fixing the base, the hole for taking out the contents of the voucher (the contents take-out port) is opened by inserting a piercing tool through the inner hole of the mouth, the concave part of the base, and the dial opening.

[0013] In the present invention, the root force of the coil spring is slidably connected to the main body in a direction in which the coil spring expands and contracts. With the coil extended to or near the limit (exit limit), insert it into the bag skin of the vouche while turning it to the root of the coil spring, and then rotate the dial and the body relatively to rotate the coil. Preferably, a spring is housed in the inner recess.

[0014] When the coil spring is inserted into the bag skin of the bouch up to the root, the spring The hole made in the bottom reaches deep inside (near the center) of the inner concave portion of the main body base. For this reason, the contents of the patch (fluid) leak out of the hole. In other words, the spring hole has a longer path extending from the hole near the opening of the contents of the bouch, which is opened at the center of the inner recess, to the outside of the main body through the outside of the inner recess, and through this path, the outside of the main body is extended. Contents are less likely to leak out.

[0015] In the present invention, it is preferable that a guard projection projecting downward is formed on a lower surface of a tip end of the coil spring.

When accommodating the distal end of the spring in the main body, the needle-like distal end of the spring is held in a floating state by the guard projection, so that the needle-like distal end of the spring is retracted. Can be prevented from piercing.

In the present invention, the bag skin is pressed between the outer periphery of the coil spring and the inner surface of the inner recess, whereby a seal is formed between the coil spring and the inner recess. In other words, there is no need to provide a sealing member such as knocking.

[0018] The method for extracting a fluid according to a specific embodiment of the present invention is a method for extracting a fluid from a die attached to an outer surface of a resin film bag (bouch) in which a fluid (content) is packed and sealed. A method of extracting a body, comprising: a base having a flange-shaped base portion applied to an outer surface of the vouch and a cylindrical mouth extending from the base; and a voucher having a portion to which the base is applied. Fixing means for pulling and fixing the bag skin into an inner recess formed in the base communicating with the inner hole of the mouth, wherein the fixing means has a needle-like tip, and A coil spring whose base can be fitted and accommodated in the inner concave portion of the main body base in the state, and a base of which is connected to the main body; and a rotatable attachment to the main body base; Abutting the side of the coil spring And a dial having an opening formed so as to press the coil spring into the inner concave portion. By rotating the dial and housing the coil spring in the inner recess, the bag skin is pulled in and fixed between the outer periphery of the coil spring and the inner surface of the inner recess. A hole is formed in the bag skin into which the bow I has been inserted, and the voucher force fluid is extracted through the hole. [0019] In another embodiment of the present invention, the bouch-mounted base is provided with a ring-shaped skirt connected to the base of the coil spring and communicating with the base. When the spring is inserted, the hole in the bag skin is expanded and guided so as to cover the periphery of the skirt, and the contents can be taken out through the inner hole of the skirt and the inner hole of the mouth.

By providing the coil spring with a skirt portion, the contents extraction port can be opened in the bag skin, following the operation of inserting the coil spring into the bag skin. For this reason, there is no need to separately provide a perforating means for perforating the drawn bag skin.

In addition, a hole (content extraction port) opened in the bouch is sandwiched between the main body and the skirt outside the skirt of the coil spring, and the content passes through the inner hole of the skirt, so that the extracted content is the voucher. No direct contact with the edge of the hole. For this reason, there is no possibility that dirt or the like attached to the outer surface of the bouch may be mixed into the contents.

[0021] In the present invention, the coil spring is turned so as to cover the outer periphery of the skirt portion so as to cover the outer periphery of the bag skin while expanding the hole, and then house the coil spring in the inner concave portion. Then, since the hole of the bag skin can be finally accommodated in the main body, it is possible to prevent leakage of the pore contents.

[0022] In another specific embodiment of the present invention, the bouch-attached base is attached to an outer surface of a resin film bag (bouch) in which a fluid (the contents) is packed and sealed. A base serving as an outlet for a fluid, the base having a flange-shaped base applied to the outer surface of the vouch and a cylindrical opening extending from the base; and a voucher bag of a portion to which the base is applied Fixing means for pulling the skin into an inner recess formed in the base communicating with the inner hole of the mouth, and fixing the skin, wherein the fixing means has a needle-like panel part at the tip end, and A ring-shaped skirt portion provided at a base of the spring portion and communicating with the mouth portion, and can be fitted and accommodated in an inner concave portion of the main body base portion in a compressed state, and the skirt portion is A coil spring connected to the main body; A dial having an opening formed with an edge which abuts against the side of the element wire of the coil spring during rotation and pushes the coil spring to be received in the inner concave portion. Having a panel portion of the coil spring from the dial opening to the inside. After piercing the bag skin of the vouch in a state of being out of the concave portion and turning the main body, the hole of the bag skin is covered while spreading along the outer periphery of the skirt portion, and then the dial is rotated. Then, the coil spring is accommodated in the inner concave portion, and at this time, the sac is sandwiched and fixed between the outer periphery of the coil spring and the inner surface of the inner concave portion.

[0023] By using this base, the operation of inserting the coil spring into the vouch while turning it, the operation of further turning the coil spring to open the content extraction hole in the bag skin of the vouch, and rotating the dial with respect to the main body Then, the coil spring is accommodated in the main body, and the bag skin is pulled into the main body, whereby the base can be attached to the vouch and the contents extraction hole can be opened.

[0024] In the present invention, the main body has a middle cylinder connected to the mouth and extending into an inner concave portion of the main body base, and a skirt portion of the coil spring is fitted around an outer periphery of the middle cylinder. It can slide in the axial direction of the middle cylinder.

[0025] Since the coil spring can be slid in the axial direction with respect to the main body, when the coil spring is pulled into the main body, it is possible to pull up the hole of the bag that is drawn in with the coil spring almost straight without twisting.

[0026] In the present invention, it is preferable that a recess is formed in the inner concave portion of the main body base so that the outer periphery of the base of the spring portion of the coil spring substantially adheres.

[0027] Since the portion around the hole of the bag skin can be held between the base of the spring portion and the recess, the hole can be substantially sealed. In addition, it is possible to avoid a situation in which a portion around the hole of the bag skin loses its cap strength or the hole is broken.

[0028] In the present invention, it is preferable that the side surface shape force of the panel portion of the coil spring also expands toward the tip end of the coil spring.

[0029] In the initial stage of the operation of housing the coil spring in the main body, the diameter of the coil spring is small, so that friction with the inner surface of the main body flange portion can be avoided, and the coil spring can be pulled in with a relatively small force.

[0030] In the present invention, the dial and the main body base are rotatably attached by screwing means, and the screwing means is a spiral groove formed on the outer periphery of the main body base. And a projection which is screwed into the spiral groove formed on the dial. It is preferable that a stop is provided at a start point and an end point of the spiral groove.

[0031] By realizing the end of the tightening of the dial, it is possible to know that the coil spring has been completely housed in the main body.

[0032] In the present invention, a lead portion is provided between the panel portion of the coil spring and the outer periphery of the skirt portion for expanding a hole of the bag skin when the coil spring is inserted into the bag skin. I prefer to

In this case, as the lead portion, a root portion of the panel portion of the coil spring may be a spiral projection in a form of being spirally wound around the skirt portion one or more times.

[0033] One end of the hole of the bag skin is hooked on the lead portion, and the one end hooked by the rotation of the coil spring is stretched with a bow I, thereby widening the hole.

The invention's effect

[0034] As is clear from the above description, according to the present invention, it is possible to provide a voucher-mounted base that is easy to operate. Since this base can be attached to the sack skin of the notch without using an adhesive, it is sanitary and can be attached without being greatly affected by the surface condition of the sack skin. BEST MODE FOR CARRYING OUT THE INVENTION

(First Example)

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an exploded perspective view showing a configuration of a vouch-attached base according to an embodiment of the present invention.

2 is a diagram showing the configuration of the base of FIG. 1, wherein FIG. 2 (A) is a front view, and FIG. 2 (B) is a front sectional view.

The base 1 is composed of a main body 10 applied to the outer surface of the vouch, and fixing means 30 for pulling the bag of the vouch and fixing the same to the main body 10. When the base 1 is actually used, although not shown, after the bag skin is fixed to the main body, a perforating means for opening the contents taking-out opening in the bag skin and a cap for opening and closing the contents taking-out opening are provided. Usually used together.

First, the structure of the main body 10 will be described. FIG. 3 is a view for explaining the structure of the main body, wherein FIG. 3 (A) is a plan view, FIG. 3 (B) is a front view, FIG. 3 (C) is a bottom view, and FIG. 3 (D) is a front sectional view. It is.

The main body 10 has a base portion 11 that protrudes outward in a flange shape applied to the outer surface of the bouch, and a cylindrical mouth portion 21 in which the central portion of the base portion 11 also extends vertically. Through the inner hole 22 of the mouth 21, the contents of the bouch are extracted.

The base 11 has an inner recess 13 that opens downward, and the inner recess 13 communicates with the mouth inner hole 22. A step 15 is formed along the outer periphery of the upper end of the base 11. An insertion hole 23 extending in the axial direction of the inner hole 22 of the mouth 21 is formed on the outer periphery of the inner hole 22. The insertion hole 23 is for slidably connecting a coil spring 31 described later to the main body 10. The insertion hole 23 is a room surrounded by an inner wall, an outer wall, both side walls, and a back wall, and communicates with the inner recess 13 of the base 11. A guide groove 25 extending in the length direction of the insertion hole 23 is formed on the inner wall. The groove 25 does not communicate with the inner recess 13 of the base 11. A screw 27 that is screwed into a cap (not shown) is formed at the tip of the mouth 21.

Next, the fixing means 30 will be described.

The fixing means 30 includes a coil spring 31 slidably connected to the main body 10 and a dial 51 rotatable with respect to the main body 10.

FIG. 4 is a diagram showing the structure of the coil spring. FIG. 4 (A) is a plan view, FIG. 4 (B) is a front view, and FIG. 4 (C) is a side view.

In this example, the coil spring 31 has a plate-shaped panel portion 33 wound about one and a half turns. The inner diameter of the panel 33 is substantially equal to the inner diameter of the inner hole 22 of the main body opening 21, and the outer diameter is substantially equal to the inner diameter of the inner recess 13 of the main body base 11. At the base of the panel portion 33, a projecting piece 35 inserted into the insertion hole 23 of the main body opening 21 is formed. FIG. 4 (A) Force The projecting piece 35 is formed so as to extend in the direction of expansion and contraction of the spring 31 in contact with the inner periphery of the panel part 33 so as to provide a component force. And it is divided into three axially extending pieces along the inner circumference. At the upper end of the central piece, a projection 37 projecting toward the center of the coil spring 31 is formed.

The tip of the panel 33 is a needle 39 that is curved downward. Further, on the lower surface of the front end of the panel portion 33, a guard projection 4 protruding downward extending in the needle line direction of the panel portion 33 is provided. 1 is provided.

[0040] A method of slidably connecting the coil spring 31 to the main body 10 will be described with reference to Figs.

First, the coil spring 31 is positioned in the inner concave portion 13 of the main body base 11, and the protrusion 35 of the spring is inserted into the insertion hole 23 of the main body opening 21. After the central piece of the projection pieces 35 is elastically deformed at the time of insertion, the projection 37 of the same piece fits into the guide groove 25. As a result, the coil spring 31 cannot rotate with respect to the main body 10 and has a length (for example, 5 mm) corresponding to the length of the guide groove 25 in the axial direction of the main body 10 (the direction in which the spring 31 expands and contracts). Slidably fixed. Further, since the protrusion 37 is fitted in the guide groove 25, the spring 31 does not fall off from the main body 10.

As described above, since the outer diameter of the panel portion 33 of the coil spring 31 is substantially equal to the inner diameter of the inner concave portion 13 of the main body base 11, the spring 31 is compressed when the coil spring 31 is compressed in the axial direction. Can be fitted and accommodated in the inner recess 13 of the main body base 11.

FIG. 5 is a view showing the structure of the dial. FIG. 5 (A) is a plan view, FIG. 5 (B) is a front view, FIG. 5 (C) is a bottom view, and FIG. 5 (D) is a view. FIG. 5B is a sectional view taken along the line JJ.

The dial 51 has a circular bottom wall 53 and a cylindrical side wall 55, and has an inner recess 57 surrounded by both walls. The inner diameter of the inner concave portion 57 is slightly larger than the outer diameter of the main body base 11, and the base 11 is fitted. A plurality of vertically extending ribs 59 are formed on the outer surface of the side wall 55 to improve the hooking force when the dial 51 is turned by hand. A plurality of protrusions 61 extending inward are formed at the upper end of the side wall 55.

A substantially elliptical opening 62 is formed in the bottom wall 53. The opening 62 acts as a content extracting portion 63 opened at the center of the bottom wall 53 and a guide portion 65 for drawing in the coil spring 31. The content extracting section 63 is a semicircle having a diameter substantially the same as the inner diameter of the inner hole 22 of the main body opening 21 as shown in FIG. The guide portion 65 is formed so as to project from the content extracting portion 63 to the outer peripheral side. The contour of the outer periphery of the guide portion 65 is substantially the same circle (arc) as the contour of the outer periphery of the panel portion 33 of the coil spring 31. A tapered chamfer 65a is formed at an edge portion of the guide portion 65 (a portion to be rubbed by the spring 31; see FIGS. 1 and 2). With reference to FIGS. 1 and 2, the overall configuration of the base 1 will be described.

As described above, the coil spring 31 is slidably connected to the main body 10 by inserting the projection 35 of the spring 31 into the insertion hole 23 of the main body 10 as described above. The main body base 11 (inner recess 13) is fitted into the inner recess 57 of the dial 51. Then, as shown in FIG. 2 (B), a protrusion 61 formed at the upper end of the side wall of the dial 51 fits into the groove 15 of the main body base 11, and the dial 51 and the main body 10 are rotatably fixed. .

In the coil spring 31, the projecting piece 35, the majority of the force panel 33 in the inner recess 57, protrudes downward from the guide 65 on the dial bottom wall 53. The projection 37 of the projection 35 of the spring 31 is located at the lower end of the guide groove 25 of the insertion hole 23 of the main body 10. In other words, the coil spring 31 is in a state of protruding most downward from the main body 10 (in other words, in a state of being movable upward), and the base of the coil spring 31 (the root of the protruding piece 35) is located on the dial bottom wall. Reached just above 53!

A method of attaching the base 1 to the vouch will be described. This method consists of two operations: an operation of inserting the coil spring 31 into the voucher P while rotating the coil spring 31, and an operation of subsequently rotating the dial 51 with respect to the main body 10 and housing the coil spring 31 in the main body 10. .

FIG. 6 is a diagram showing a state where the coil spring is inserted into the vouch.

First, while holding the main body 10 in the initial state shown in FIG. 2, the needle portion 39 of the spring 31 is inserted into the bag skin P of the bouch. Then, as shown in FIG. 6 (A), a hole B having a size substantially corresponding to the width of the panel portion 33 of the spring 31 is opened in the skin P. Then, while turning the main body 10 clockwise as viewed from the plane, the spring 31 also advances the opening B force into the vouch P. Finally, the main body 10 is rotated by the number of turns of the coil spring 31 (about one and a half steps) until the dial 51 hits the bag skin of the vouch P, as shown in FIG. At this time, the coil spring 31 has penetrated into the bouch P almost to the base of the projection 35.

FIG. 7 is a diagram showing a state when the dial is rotated.

Next, hold the mouth portion 21 of the main body 10 with one hand and fix it, and hold the dial 51 with the other hand to the main body 10 in the same direction as the winding direction of the spring 31 (in this example, viewed from a plane). (Clockwise). The spring 31 is fixed to the body 10 so that it cannot rotate. When the dial 51 is rotated, the guide portion 65 of the opening 62 of the dial bottom wall 53 moves from the base of the spring 31 along the needle line of the spring 31. Then, the spring 31 is pushed up from the base to above the dial bottom wall 53, that is, to the inner recess 13 of the main body base 11. At this time, the lower surface of the spring 31 is pushed up without being rubbed against the chamfer 65a of the guide portion 65. Then, along with the base of the spring 31, the bag skin P is also pulled up into the inner recess 13 of the main body base 11. When the dial 51 is further rotated, the spring 31 is accommodated while being compressed into the inner recess 13 along the needle line from the base. At the same time, the spring 31 can be moved upward by a length of the guide groove 25 with respect to the main body 10, so that the spring 31 is slightly pushed up. Then, the bag skin P is drawn into the inner concave portion 13 while being squeezed by the opening 62 of the dial bottom wall 53, with the hole B opened by the needle portion 39 of the spring 31 first.

[0049] During this operation, since the main body 10 is fixed, the planar position of the spring 31 does not change, and the planar position of the hole B formed by the needle portion 39 of the spring 31 in the bag skin P is changed. The position does not change, but in fact, when the spring 31 is pulled up into the inner recess 13, the bag skin P is pulled by the opening 62 of the dial bottom wall 53 and is inserted into the bow I so that it is slightly twisted. hand! / When the contents of the bouch are viscous, the bag skin is pushed by the contents and is pulled straight up substantially because the bag skin is under internal pressure.

FIG. 8 is a view showing a state where the spring is pulled into the main body. FIG. 8 (A) is a cross-sectional perspective view of the entire base, and FIG. 8 (B) is a cross-sectional view of the tip of the spring. .

When the dial 51 is rotated one and a half turns, the entire spring 31 is pushed up into the inner recess 13 of the main body base 11. The bag skin P is pulled from the hole B portion, covers the outer peripheral surface of the panel portion 33 of the spring 31, and is drawn into the inner recess 13 of the main body base 11 so as to be squeezed by the opening 62 of the dial bottom wall 53. It is. Finally, the bag skin is tightly sandwiched between the upper surface, the outer surface, and the lower surface of the panel portion 33 of the spring 31 and the inner surface of the main body concave portion 13 and the upper surface of the dial bottom wall 53. Is fixed to Bauchi P. As described above, since the outer diameter of the spring 31 is substantially equal to the inner diameter of the concave portion 13 in the main body, the outer periphery of the spring 31 and the inner peripheral surface of the concave portion 13 in the main body come into close contact with each other, and the space therebetween is sealed. Once the bag skin P is pulled in, it becomes difficult to remove it.

Further, the bag skin P is pressed against the lower surface of the inner concave portion 13 at the uppermost surface of the panel portion 33. here Since the projecting piece 35 of the spring 31 is formed in contact with the inner periphery of the panel portion 33, the area of the uppermost surface of the panel portion 33 can be increased, and the pressing force can be increased.

When the distal end portion of the spring 31 is pulled into the concave portion 13 in the main body, the guard projection 41 hits the edge of the guide portion 65 and is lifted up on the bottom wall 53. That is, as shown in FIG. 8B, the needle portion 39 at the tip of the spring is pulled by the guard projection 41 without hitting the bottom wall 53, and is held in a state of floating from the bottom wall 53. Therefore, it is possible to prevent the needle portion 39 from piercing the bag skin P drawn into the inner concave portion 13. Then, when the needle portion 39 is pulled into the inner concave portion 13, it does not come into contact with the bag skin again. For this reason, when the content of the bouch becomes small, the needle portion 39 does not accidentally make a hole in the bag skin on the other side.

Next, a method of perforating the bag skin P fixed to the main body 30 will be described.

FIG. 9 is a diagram showing a state in which the perforating means is inserted into the base.

FIG. 10 is a diagram showing a state in which the contents take-out opening is opened in the bag skin.

When the entirety of the spring 31 is accommodated in the inner concave portion 13, the bag P is sandwiched between the inner concave portion 13 of the main body base 11 and the outer periphery of the spring 31, and covers the entire spring 31 in a tensioned state. I have. Then, as shown in FIG. 9, a cutter (piercing means) 80 is inserted into the inner hole 22 of the mouth 21 of the main body 10. As the cutter 80, for example, one having four radially extending blades 81 can be used. When the cutter 80 is lowered, the tip 83 where the blades 81 intersect pierces the bag skin P at the center of the inner concave portion 13 of the main body base 11, and makes a hole in the bag skin P. When the force cutter 80 is further lowered, four cuts A extending radially from the holes are formed in the bag skin P along each blade as shown in FIG. This cut A is the opening for taking out the contents. Since the cut A extends in four directions of the penetrated point force, the cut end of the sac becomes almost triangular. This piece protrudes in a cantilever manner, but its base is wide, so the body of the sack is difficult to tear off.

Then, raise the cutter 80.

Here, the hole B first opened in the bag skin P with the needle 39 at the tip of the spring reaches the base of the spring 31 (the root of the projection 35). Since the projecting piece 35 is formed in contact with the inner periphery of the spring 31, the position of the hole B is close to the contents taking-out opening formed in the center of the inner concave portion 13 of the main body base 11. Alternatively, when drilling with cutter 80, It may communicate with the take-out opening. By positioning the hole B as close as possible to the opening for taking out the contents, the path extending between the hole B force concave portion 13 in the body and the spring 31 to the outside of the main body is lengthened. That is, the contents of the bouch can be prevented from leaking from the hole B through this path (between the concave portion in the main body and the outer periphery of the spring).

After the opening for taking out the contents of the bouch is opened, the cap is screwed onto the screw 27 of the mouth 21 to close the contents taking-out opening. When extracting the contents of the vouch, if a quantitative extraction mechanism is attached to the mouth 21, the vouch can be used directly as a hopper.

When the strength of the bag skin of the bouch is low, a reinforcing sheet may be attached to a portion of the bag skin where the base is to be attached. In this case, if the reinforcing sheet is stuck at a room temperature at which the voucher is not filled, the adhesiveness is good.

[0056] If all of the above components (main body 10, coil spring 31, dial 51) are made of a polycarbonate resin or the like that is safe for food hygiene, the contents can also be used for packing foods such as creams and jams. Applicable. Since the components are connected by mechanical means, there is no need to use hygienic adhesives. If the contents are other than food and there is no need to control the sanitary surface! In such a case, other materials may be used.

(Second Embodiment)

FIG. 11 is an exploded perspective view showing the configuration of a voucher-attached base according to another embodiment of the present invention.

12 is a diagram showing the configuration of the base of FIG. 11, in which FIG. 12 (A) is a front view, and FIG. 12 (B) is a front sectional view.

Like the base of FIG. 1, the base 101 of this example also includes a main body 110 applied to the outer surface of the vouch, and fixing means 150 for pulling in the bag of the notch and fixing it to the main body 110. The difference between the base 101 of this example and the base 1 of FIG. 1 is that the base 101 of this example is integrally provided with a punching means for making a hole in the drawn bag. In other words, it is possible to open the hole to take out the contents while pulling the bag skin of the bouch into the base.

First, the structure of the main body 110 will be described.

FIG. 13 is a view for explaining the structure of the main body. FIG. 13 (A) is a front view, FIG. 13 (B) is a front sectional view, and FIG. 13 (C) is a bottom view. The main body 110 has a base 111 and a cylindrical mouth 125 extending vertically upward with the central force of the base 111. Further, the mouth portion 125 is provided with a middle cylinder 127 extending in the base portion 111 continuously. The contents of the bouch are extracted through the inner cylinder 127 and the inner hole of the mouth 125.

[0059] The base 111 has an outer cylindrical portion 113 connected to the mouth 125, and a flange portion 115 connected to the outer cylindrical portion 113 and projected to the outer periphery in a flange shape. As shown in FIG. 13 (B), the middle cylinder 127 passes through the center of the outer cylinder 113 and the flange 115 from the lower end of the mouth 125 and slightly lower than the lower surface of the lower end of the flange 115. Extending until it sticks out.

[0060] The flange portion 115 has an inner concave portion 117 that opens downward. In this example, approximately two and a half spiral grooves 119 are formed on the outer peripheral surface of the flange portion 115. A dial 180 described later is screwed into the spiral groove 119. Stirrups are provided at the tip and the end of the spiral groove 119. Below the spiral groove 119 on the outer peripheral surface of the flange portion, four concave portions 121 extending in the axial direction, in this example, are formed. As will be described in detail later, the claw portion 195 of the dial 180 passes through these recesses 121 when the dial is screwed.

As shown in FIG. 13B, an annular concave portion 129 extending in the axial direction is formed between the outer cylinder portion 113 and the middle cylinder 127. A skirt portion 171 of a coil spring 160 described later fits into the concave portion 129. Four guide grooves 131 extending in the axial direction are formed on the outer peripheral surface of the middle cylinder 127. As will be described in detail later, the guide protrusions 173 of the skirt portion 171 of the coil spring 160 engage with these guide grooves 131.

Further, a base (fixed spring 163) of a panel 161 of a coil spring 160 (see FIGS. 11 and 14) is accommodated in a lower portion of an annular recess 129 between the outer cylinder 113 and the middle cylinder 127. A recess 133 is formed. The recess 133 is formed in a spiral shape from a position corresponding to the start end 161a of the panel portion 161 and, as described later with reference to FIG. 21, the upper surface of the base (fixed panel portion 163) of the panel portion 161 and The sides adhere perfectly via the bag skin of the bouch.

Next, the fixing means 150 will be described.

The fixing means 150 includes a coil spring 160 slidably and non-rotatably connected to the main body 110 and a dial 180 rotatably attached to the main body 110.

First, the coil spring 160 will be described. FIG. 14 is a view showing the structure of the coil spring. FIG. 14 (A) is a front view, FIG. 14 (B) is a rear view, and FIG. 14 (C) is a plan view.

In this example, the coil spring 160 has a panel part 161 wound about three turns, and a cylindrical skirt part 171 provided at the base (start end) of the panel part 161. As shown in FIG. 14 (B), the starting end 161a of the panel portion 161 is located on the outer peripheral surface of the skirt portion 171. Then, after the circumference of the skirt portion 171 is wound around the circumference of the skirt portion 171 by about one and a half spirals from the start end 161a, the skirt portion 171 spirally extends downward from the lower end of the skirt portion 171. That is, the portion from the starting end 161a to about one and a half circles is fixed to the skirt part 171 (this part is referred to as a lead part 163), and the part about one and a half circles beyond the lead part 163 contracts (this part). 165). As shown in FIG. 14 (A), between the lower end of the skirt portion 171 and the free portion 165, there is a wedge-shaped recess 169. In the circumferential direction, the starting end position 161a of the panel 161 is located approximately 180 ° upstream from the position of the wedge-shaped recess 169 in the direction of winding of the panel.

The inner diameter of the panel portion 161 is substantially equal to the outer diameter of the middle cylinder 127 of the main body 110, and the outer diameter is increased from the starting end 16 la toward the tip 161b. That is, the wire diameter of the panel portion 161 gradually increases from the starting end 16 la toward the leading end 161 b. The diameter of the portion of the tip 161b of the panel portion 161 for one round is also substantially equal to the diameter of the inner concave portion 117 of the flange portion 115 of the main body 110. The tip 161b of the panel portion 161 has a needle shape curved slightly downward. Further, a guard projection 167 protruding in the axial direction of the panel portion 161 is formed on the lower surface of the front end of the panel portion 161.

As shown in FIG. 14 (C), four guide projections 173 extending in the axial direction, in this example, are formed on the inner peripheral surface of the skirt portion 171. These guide projections 173 engage with the guide grooves 131 of the middle cylinder 127 of the main body 110 as described above. Then, the skirt portion 171 is fitted to the middle cylinder 127 of the main body 110, and can slide in the axial direction of the middle cylinder 127.

That is, the coil spring 160 is fixed so as not to rotate with respect to the main body 110 and to be slidable in the axial direction of the main body 110 (the direction in which the spring expands and contracts). When the coil spring 160 slides the most in the direction of the main body 110, the upper end of the skirt portion 171 reaches the uppermost end of the annular concave portion 129 between the outer cylinder portion 113 and the middle cylinder 127, and the panel portion 161 The base portion (lead portion 163) is accommodated in a recess 133 formed in the lower part of the space. FIG. 15 is a view showing the structure of the dial. FIG. 15 (A) is a front view, FIG. 15 (B) is a plan view, and FIG. 15 (C) is a sectional view.

The dial 180 has a circular bottom wall 181 and a cylindrical outer wall 191, and has an inner recess 193 that opens upward. The diameter of the inner recess 193 is slightly larger than the diameter of the flange 115 of the main body 110. At the upper end of the side wall 191 are formed four inwardly extending claws 195 in this example. These claws 195 are screwed into the spiral grooves 119 of the main body flange 115 described above. For this reason, each claw portion 195 has a different height depending on the height position of the spiral groove 119. That is, the height gradually decreases in the circumferential direction from the uppermost position. These claws 195 can be elastically deformed outward by notches 196 on both sides thereof.

A plurality of ribs 197 extending in the vertical direction are formed on the outer surface of the side wall 191 to improve the hooking force when turning the dial by hand.

[0069] A substantially oval opening 183 is formed in the bottom wall 181. The opening 183 includes a content extraction opening 185 opened at the center of the bottom wall 181 and a guide opening 187 for drawing in the coil spring. The contents extraction opening 185 has a semicircular shape having substantially the same diameter as the inside diameter of the middle cylindrical portion 127 of the main body 110. The guide opening 187 is formed so as to project outward from the contents extraction opening 185. The contour of the outermost periphery of the guide opening 187 is a circular arc having substantially the same shape as the contour of the outer periphery of the panel free portion 165 of the coil spring 160. The edge of the guide opening 187 is tapered.

Next, how to assemble the base 101 and the overall configuration will be described.

First, the coil spring 160 is attached to the main body 110. At this time, after aligning the position of the starting end of the recess 133 of the main body 110 with the position of the starting end 161a of the panel portion 161 of the coil spring 160, the guide projection 173 of the skirt portion 171 of the coil spring 160 is attached to the middle cylinder of the main body 110. The skirt portion 171 is fitted into the middle cylinder 127 by fitting into the guide grooves 131 of the first and second cylinders 127. Thus, the coil spring 160 is attached to the main body 110 so as not to rotate and to be slidable in the axial direction of the main body 110.

Next, the dial 180 is rotatably attached to the flange 115 of the main body 110. At this time, first, the directional force of the tip 161b of the coil spring 160 attached to the main body 110 is passed through the opening 183 of the bottom wall 181 of the dial 180, and the position of the claw portion 195 of the dial 180, Adjust the position of the recess 121 of the flange 115. Then, each claw portion 195 of the dial 180 is elastically deformed outward so that each claw portion 195 is screwed into the spiral groove 119 of the flange portion 115, and then each claw portion 195 is returned to the original position. Fit into the spiral groove 119 of the flange 115. As a result, the dial 180 and the main body 110 are rotatably fixed.

[0072] The dial 180 has a position where the lowermost claw portion 195 of the dial 180 abuts the end of the spiral groove 119 of the flange portion 115 and a highermost position of the claw portion 195 with respect to the main body 110. It rotates about two turns between the position where it contacts the beginning of the groove 119. At the position where the dial 180 contacts the end of the spiral groove 119 (in the initial state of assembling the base 101), the dial 180 is extended from the flange 115 to the lowest position. On the other hand, at a position where the dial 180 contacts the start end of the spiral groove 119, the flange portion 115 is housed in the inner recess 193 of the dial 180. In addition, since the stirrup is provided at the start end and the end of the spiral groove 119, once the dial 180 is attached to the flange portion 115, it does not come off from the flange portion 115.

Further, since the height of each claw portion 195 is determined in accordance with the height of the spiral groove 119, when the dial 180 and the flange portion 115 are screwed together, they take the same horizontal posture.

The coil spring 160 has a panel lead portion 163 mounted on the bottom wall 181 of the dial 180, and a tip portion (free portion) 165 protruding from the guide opening 187 of the bottom wall 181 of the dial 180. I have. The wedge-shaped concave portion 169 between the skirt portion 171 and the panel free portion 165 of the coil spring 160 is located immediately below or on the same surface as the dial bottom wall 181.

As described above, since the panel lead portion 163 is placed on the dial bottom wall 181, the coil spring 160 can be prevented from dropping from the main body 110.

Next, a method of attaching the base 101 to the vouch will be described.

The method of attaching the base 101 to the vouch includes (1) an operation of inserting the coil spring 160 into the pouch while rotating the coil spring 160, and (2) an operation of turning the coil spring 160 further to open the contents extraction hole in the bag skin of the vouch, 3) By rotating the dial 180 with respect to the main body 110, the coil spring 160 is housed in the main body 110 and the bag skin is pulled into the main body 110, and the operation is mainly performed.

First, (1) an operation of inserting the coil spring 160 into the vouch while rotating it will be described. The

FIG. 16 is a diagram illustrating a state in which a coil spring is inserted into a vouch. First, while holding the main body 110 in the initial state shown in FIG. 12, the needle-like tip 161b of the coil spring 160 is pierced into the bag skin P of the bouch. Then, as shown in FIG. 16, a substantially linear opening B having a width of the panel portion (pane-free portion 165) of the coil spring 160 is opened in the bag skin P. Then, while turning the main body 110 clockwise in FIG. 16 when viewed from above, the panel B free portion 165 of the coil spring 160 also advances the opening B force into the vouch.

FIG. 17 is a view showing a state in which the coil spring is made to enter the inside of the vouch. FIG. 17 (A) is a front view, and FIG. 17 (B) is a front sectional view.

The coil spring 160 penetrates into the bouch until one end of the opening B of the bag skin P hits the wedge-shaped recess 169 at the boundary between the skirt portion 171 and the panel-free portion 165. At this time, the main body 110 is rotated by the number of turns (about one and a half) of the panel free portion 165 of the coil spring 160. Here, one side of the opening B of the bag skin P covers the upper surface of the panel-free part 165 (this side is called an upper cut), and the other side is cut into the lower surface of the panel-free part 165 (this side is a lower cut). ).

Next, (2) an operation of further rotating the coil spring 160 to open a content extraction hole in the bag skin P of the patch will be described.

FIG. 18 and FIG. 19 are diagrams schematically illustrating a state in which the contents extraction hole is opened in the bag skin of the bouch.

As a result of the above operation (1), as shown in FIG. 18A, an opening B having substantially the same size as the cross section of the panel-free portion 165 is opened in the bag skin P. In this operation, the main body 110 is further rotated clockwise in the figure as viewed from a plane force. Since the coil spring 160 is non-rotatably fixed to the main body 110, the coil spring 160 also rotates with the rotation of the main body 110. Then, as shown in FIG. 18 (B), the wedge-shaped concave portion 169 (hereinafter referred to as a lead groove) at the boundary between the skirt portion 171 and the panel free portion 165 pivots clockwise in the figure, and was caught in the lead groove 169. One end E1 (referred to as a lead edge) of the opening B is pulled into the lead groove 169. On the other hand, since the bag skin P does not move, the position of the other end E2 (referred to as a fixed edge) of the opening B is almost the same as the initial position shown in FIG. Then, as the lead groove 169 turns, The opening S 1 is pulled so as to cover the spring lead portion 163 while being wound around the skirt portion 171. On the other hand, the lower cut S2 extends linearly connecting the fixed edge E2 of the opening B and the lead edge E1. That is, the length of the opening B becomes longer.

Further, as shown in FIG. 18 (C), when the main body 110 is rotated approximately 180 ° clockwise in the figure from the initial state (FIG. 18 (A)) also with respect to the plane force, the rotation of the lead groove 169 is achieved. At the same time, the lead edge E 1 turns. Then, the upper incision S1 rises toward the starting end 161a of the panel portion 161 so as to cover the spring lead portion 163 while being wound around the skirt portion 171. On the other hand, the lower cut S2 extends linearly connecting the fixed edge E2 of the opening B and the lead edge E1. As a result, the opening B has a substantially semicircular shape formed between the inner surface of the skirt portion 171 and the lower cut S2 extending between the fixed edge E2 and the lead edge E1.

When the main body 110 is further turned clockwise in the figure by about 270 ° from the initial state, the shape of the opening B becomes substantially circular as shown in FIG. 19 (A). Thus, when the main body 110 is turned substantially one round, the upper incision S1 spreads over the circumference of the skirt portion 171. Then, as shown in FIG. 19B, the lead edge E1 and the fixed edge E2 reach the same circumferential position. However, at this position, the panel lead portion 163 (the portion approximately 1Z4 from the starting end 161a of the panel portion 161) above the upper cut S1 has not penetrated into the bouch. This is because, in the circumferential direction, the starting end position 161a of the panel 161 is located at a position force of about 180 ° upstream of the lead edge 169.

[0080] Therefore, after the main body 110 has made one round, it is further turned about 180 ° in the same direction. Then, as shown in FIG. 19 (C), the upper cut S1 and the lower cut S2 of the opening B are wound around the skirt 171 and cover the panel lead portion 163, and the entire panel portion 161 enters the inside of the vouch. At the same time, the skirt portion 171 pierces the bag skin P. The inner hole of the skirt portion 171 serves as a content extraction opening.

Here, the opening edge of the bag skin is formed by extending a linear hole B formed by piercing the coil spring 160 to the circumferential length of the skirt portion 171. For this reason, the bag skin P is wound around the skirt portion 171 with a certain force due to the force of the stretched bag skin P shrinking.

FIG. 20 is a side cross-sectional view showing a state in which the contents extraction opening is opened in the bag skin. The fixed spring portion 163 of the coil spring 160 is located above the dial bottom wall 181 as described above. Therefore, during the operation of (2), the bag skin P rises along the panel lead portion 163 while being squeezed by the opening 183 of the bottom wall 181.

Next, (3) the operation of rotating the dial 180 to accommodate the coil spring 160 in the main body 110 and pull the bag skin P into the main body will be described with reference to FIGS. 20 and 21. .

FIG. 21 is a diagram showing a state where the coil spring is drawn into the main body. First, hold the mouth portion 111 of the main body 110 with one hand, fix the dial 180 with the other hand, and hold the dial 180 with respect to the main body 110 in the same direction as the winding direction of the coil spring 160 (in this example, , Clockwise as viewed from the plane). When the dial 180 is rotated, the guide opening 187 of the dial bottom wall 181 is moved along the axis of the coil spring 160 fixed to the main body 110 toward the tip 161b. Moving. Then, the panel-free portion 165 is pushed up from the start end of the same while being compressed above the dial bottom wall 181, that is, into the inner concave portion 117 of the main body base 111. At this time, the lower surface of the none-free portion 165 is pushed up while being rubbed against the chamfer of the opening edge of the guide opening 187. Then, the coil spring 160 is pushed up in the axial direction with respect to the main body 110 along the middle cylinder 127 of the main body 110.

During this time, the dial 180 goes up along the spiral groove 119 of the main body flange portion 115 toward the main body.

The bag skin P covering the panel portion 161 of the coil spring 160 is also squeezed by the opening 183 of the dial bottom wall 181 into the inner concave portion 117 of the main body base 111 so as to be pulled by the panel lead portion 163. It is drawn in while being drawn. At this time, since the coil spring 160 is pushed up in the axial direction of the main body 110, the bag skin that is led by the panel lead portion 163 and is pulled in is pulled almost straight without being twisted.

[0085] Eventually, when the dial 180 is rotated by the number of turns of the panel-free portion 165 of the coil spring 160 (about one and a half in this example), as shown in FIG. It is drawn into the recess 117. At the same time, main body flange 115 is accommodated in inner recess 193 of dial 180. [0086] Here, since the number of the spiral grooves 119 formed in the flange 115 of the main body 110 is larger than that of the panel free part 165, even after the panel free part 165 is completely drawn into the inner recess 117, The dial 180 is rotatable with respect to the main body 110. Therefore, when the dial 180 is further rotated, one of the claws 195 of the dial 180 comes into contact with the starting end of the spiral groove 119, and the dial 180 cannot be rotated.

That is, when the dial 180 is rotated with respect to the main body 110 until it cannot rotate, the panel free portion 165 of the coil spring 160 is completely housed in the inner recess 117 as shown in FIG. become. Therefore, it is possible to know by touch that the panel-free portion 165 has been completely accommodated in the inner concave portion 117.

[0088] As described above, the panel portion 161 of the coil spring 160 has a lateral shape whose diameter increases from the start end toward the front end. For this reason, in the initial stage of retracting the panel-free portion 165, the diameter of the panel portion 161 is small, so that friction between the panel portion 161 and the side surface of the inner concave portion 117 can be avoided. Only need to be small. At the end of the retraction of the spring-free part 165, the diameter of approximately one section from the tip 161a is approximately equal to the diameter of the inner recess 117 of the main body 11, so that a relatively strong force is required.

[0089] During these operations, a force is applied such that the panel-free portion 165 is pulled toward the center of the main body due to the resistance of the bag skin P of the bouch. However, since the panel free portion 165 is fitted to the middle cylinder 127 of the main body 110, even if such a force acts, the portion 165 is not pulled out.

As can be seen from FIG. 21, the coil spring 160 is such that the skirt portion 171 enters the annular concave portion 129, and the panel portion 161 is housed in the concave portion 133 and the internal concave portion 117, and is completely inserted in the internal concave portion 117 of the main body 111. Bow I

[0091] The opening edge of the bag skin P of the bouch is sandwiched in the annular concave portion 129 between the scar portion 171 of the coil spring and the inner wall of the outer cylindrical portion 113 of the main body. The periphery of the opening edge is sandwiched between the recess 133 and the upper surface and side surface of the lead portion 163 of the coil spring 160, and the opening is substantially sealed. Further, in the portion of the bag skin P that is drawn into the inner concave portion 117, the maximum diameter portion (the portion of which the tip 161b has a force of about one line) of the panel free portion 165 of the coil spring 161 and the inner wall of the inner concave portion 117 and the dial bottom wall 181 Between you. this As described above, the portion around the opening of the bag skin P is perfectly sandwiched between the coil spring 160 and the main body 110, so that the contents of the notch do not leak the opening force of the bag skin.

When the tip 161a of the spring 160 is retracted into the recess 117 in the main body, the guard projection 167 hits the edge of the guide opening 187 and is lifted up on the bottom wall 181. Then, as in the first embodiment, the tip 161b is pulled in by the guard projection 167 without hitting the 181 and is held in a state of floating from the bottom wall 181. For this reason, it is possible to prevent the tip 161b from piercing the bag P drawn into the inner recess 117.

[0093] The contents of the bouch are extracted from the middle cylinder 127 of the main body 110 through the mouth 125. Here, the opening of the bouch is sandwiched between the coil spring 160 and the main body 110 outside the skirt portion 171 of the coil spring 160. Through the inner hole). That is, since the contents do not directly touch the edge of the hole of the bouch or the outer surface of the vouch, there is no danger that such dirt may be mixed into the contents even if the outer surface of the vouch is dirty.
