Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a straw to which blister packaging technology is applied.
[0002]
[Prior art]
Conventional straws are mainly extruded. The extruded straw was bent as a single stroke by a post-processing tube bending machine. For example, a heart shape was proposed in Japanese Utility Model Laid-Open Publication No. 53-130081, and a character shape was imitated. 682715, and a model imitating a flower is proposed in Design Registration 780974. Further, a straw having a flexible portion has been proposed in Japanese Utility Model Laid-Open No. Sho 59-118474, and a method of forming a flexible portion by post-processing after extrusion has been proposed in Japanese Patent Application Laid-Open No. Sho 60-178021. I have. Also, a straw having a bulged portion by injection has been proposed in Japanese Utility Model Laid-Open Publication No. 52-149072.
[0003]
[Problems to be solved by the invention]
When a straw tube formed by conventional extrusion molding is bent by post-processing to form characters and designs, it is limited to a simple shape that can be bent like a single stroke, for example, by bending a straw tube. When forming the annular part, in order to prevent the straw tube from collapsing, the annular part must have a curvature radius of a certain size or more, and it is difficult to express finely by the shape of the straw tube due to its restrictions. there were. In addition, the method of forming the flexible portion in the extrusion straw in a post-process requires a complicated process. In addition, in injection molding, low-cost pre-printing could not be used, and a printing method after molding had to be adopted.
[0004]
In addition, it is difficult to print a conventional tubular straw with a small frontal area because it needs an appropriate size to print a picture or a design. The printing method must be relatively slow, such as silk-screen printing or pad printing, and mass-produced straws, which are positioned as disposable products, must be printed in practice. It was difficult to do.
[0005]
For this purpose, the present invention uses a blister packaging technique to secure a relatively large surface between thin walls and narrow walls, thereby forming a relief-like undulating pattern with a relatively fine water channel of an arbitrary shape. The purpose of the present invention is to provide a blister straw that enables expression and uses a desired print such as a design or design by pre-printing at a low cost and that enables a flexible portion that does not require a complicated post-process. I have.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the invention according to claim 1 has a flange portion around the periphery, the opening side of the upper body swelled to an arbitrary external shape is faced toward the lower lid, and they are overlapped. In a blister molded body formed by welding the flange portions together in a state and sealing the opening, at least one blister molded body having an inner space formed of a continuous space portion is provided. A suction port that opens to the outside and at least one suction port that opens to the outside are simultaneously provided at arbitrary locations to communicate the internal space with the outside and allow liquid to pass through the internal space. It is a blister straw when used as a waterway.
[0007]
According to the first aspect of the present invention, a suction port and a suction port are provided at arbitrary positions of a blister molded body having a continuous internal space, thereby using the internal space as a water passage through which a liquid passes. Has become possible.
[0008]
The invention according to claim 2 is a blister straw in which the lower lid is swelled in an arbitrary shape so as to form a water passage between the upper lid and the upper body.
[0009]
According to the second aspect of the present invention, by enlarging the lower sheet into an arbitrary shape, a rich representation of the relief tone can be provided on both the front and back surfaces, and the front display portion can be further expanded three-dimensionally.

It is a blister straw when combined and welded.
[0013]
According to the fourth aspect of the present invention, since the groove having a substantially V-shaped cross section to be fitted in the upper and lower flange portions is formed at the same time as the straw main body is formed, the flexible portion that is easily bent is formed at the same time as the forming. Has become possible.
[0014]

[0020]
BEST MODE FOR CARRYING OUT THE INVENTION
Embodiments of the present invention will be described based on examples with reference to the drawings.
First Embodiment A first embodiment will be described with reference to FIGS. 1 is a front view, FIG. 2 is a cross-sectional view in the AA direction in FIG. 1, FIG. 3 is a perspective view, and FIG. 4 is a cross-sectional view in the BB direction in FIG. In the lower part 2 of the straw 1, a bulging part 6 is formed by bulging the upper sheet 4 toward the front 5 so as to have a flange part 3 around the periphery. The bulging portion 6 has a rear opening, and is formed into a shape extending in the longitudinal direction 8 with a substantially cylindrical section 7. Further, a suction port 10 is provided at the lower end of the lower portion 2 to open the suction port 10 for communicating the internal space 9 formed by the bulging portion 6 to the outside.
[0021]
Generally, the bulging portion of the blister package is used by bulging into a desired shape. Similarly, the present invention provides a straw constituted by a bulging portion having a desired relief-like undulating pattern. It is possible. In the display unit 11 connected to the upper part of the straw lower part 2, similarly to the lower part of the straw 2, the upper sheet 4 is provided so as to have a flange part 3 around the periphery and to communicate the internal space 9 and the internal space 12 formed by the bulging part 13. A bulging portion 13 bulging toward the front 5 is formed. The bulging portion 13 is a rear opening, and is further formed into a relief-shaped undulating heart shape, and is formed integrally with the bulging portion 6.
[0022]
The heart-shaped bulging portion 13 has a larger bulging width 15 in the width direction 14 and a smaller depth 16 of the bulging portion 13 so as to increase the frontal area. Further, inside the heart-shaped bulging portion 13, a letter-shaped cross-sectional reduced portion 18 having a relief-like undulating pattern extending from the upper sheet 4 toward the lower lid 17 is formed. The cross-sectional reduced portion 18 has a character shape of “L”, “0”, “V”, and “E”, and the characters are arranged side by side substantially at the center of the bulging portion 13. In the cross-section reduction portion 18, although the drink does not pass through the gap below, an area 19 through which the drink can pass around the character and between the characters is secured.
[0023]
In a straw upper part 20 connected above the display part 11, a bulging part 22 is formed by bulging the upper sheet 4 toward the front 5 so that the inner space 12 and the inner space 21 communicate with each other. The bulging portion 22 has a rear opening, extends in the longitudinal direction 8 with a substantially semi-cylindrical cross section 7, and is formed integrally with the bulging portion 13. At the upper end of the straw upper part 20, a suction port 23 that opens the internal space 21 formed by the bulging part 22 to the outside is provided. In addition, the lower lid 17 having a one-surface shape includes a lid 24 that seals the opening of the bulging portion and a flange 25 that faces the flange 3 of the upper sheet 4.
[0024]
As described above, the straw 1 of the first embodiment is bulged forward 5 so that the internal spaces formed by the bulges communicate with each other. The upper and lower sheets are opposed to each other with their sides facing the lower lid 17, and the facing flange portions of the upper and lower sheets are overlapped and heat-sealed integrally by heat sealing. In addition, as a sealing method, an arbitrary method such as heat sealing, hot melt bonding, high frequency sealing, and ultrasonic sealing may be selected and used. In FIG. 1 and FIG. 3, the hatched portions indicate the welding regions. It should be noted that the bulging molding may be performed by either vacuum molding or pressure molding, or by using them simultaneously.
[0025]
The present invention is based on the premise that the blister packaging technique is used.In recent years, even in injection molding, thin-wall processing has become possible, so the upper sheet portion having a bulging portion is formed by injection molding. Instead, the opening side of the bulge portion of the processed injection molded product is faced toward the lower lid 17, and the flange portions are overlapped and heat welded integrally by heat sealing or the like and molded. Is also good. Japanese Utility Model Application Laid-Open No. 52-149072 is molded by an injection method having no flange on both sides, so that the bonding technique of blister packaging using a heat sealing method on the flange cannot be used, and preprinting cannot be used.
[0026]
The material of the upper sheet 4 is a thermoplastic synthetic resin, and the lower lid 17 may be a desired material such as a synthetic resin, a bondable paper, aluminum, or a composite thereof, but the upper and lower sheets are made of the same material. If it is, disposal processing is easy. Further, when a synthetic resin foam is used for the lower sheet, the overall buoyancy can be made lighter than water, so that it is easy to collect without sinking in the sea or river. Further, when the upper and lower sheets are made of a biodegradable synthetic resin, even if the upper and lower sheets are dumped in the soil at the time of disposal, they are decomposed by microorganisms in a short time, and environmental problems such as pollution by waste are unlikely to occur.
[0027]
Second Embodiment A second embodiment will be described with reference to FIGS. 5 is a perspective view of the second embodiment, FIG. 6 is a cross-sectional view taken along the line CC in FIG. 5, and FIG. 12 is a detailed view of another alternative configuration around the suction portion viewed from above the longitudinal direction 38. In the second embodiment, similarly to the first embodiment, a straw having a lower lid 17 around the periphery that becomes a water passage except for a part thereof and an inner space communicating with a bulging portion sealing an opening is used as a water passage.
[0028]
At the lower end 26 of the straw, branch swelling portions 30 and 31 are formed, which are divided into two parts at a rear opening where the upper sheet 28 swells toward the front 29 so as to have a flange 27 around the periphery. Suction ports 32 and 33 for opening the respective internal spaces to the outside are provided at the ends of the branch bulging portions 30 and 31 so as to open. A substantially circular surface 34 having an inner flange portion connected thereto is formed between the two branch bulging portions 30 and 31, and a fork-like tip 35 having a plurality of substantially V-shaped cuts formed at the tip thereof. The two bulging portions 30 and 31 and the substantially circular surface 34 can be used as a fork, a spoon or a stirrer.
[0029]
A lower portion of the straw 37 extending above the lower end portion 26 of the straw has a flange portion 27 around the upper portion and further has an upper sheet 28 so that the internal space formed by the branch bulging portions 30 and 31 and the internal space formed by the bulging portion 39 communicate with each other. A bulging portion 39 is formed by bulging toward the front 29. The bulging portion 39 is a rear opening, extends in the longitudinal direction 38 with a substantially semi-cylindrical cross section, and is formed integrally with the bulging portions 30 and 31.
[0030]
In the display section 40 connected to the upper part of the straw lower part 37, similarly to the straw lower part 37, the flange part 27 is provided in the periphery, and the inner space formed by the bulging part 39 and the inner space formed by the bulging part 41 communicate with each other. A bulging portion 41 is formed by bulging the upper sheet 28 toward the front 29. The bulging portion 41 is a rear opening and is formed integrally with the bulging portion 39.
[0031]
The bulging portion 41 has a large bulging width 43 in the width direction 42 so as to increase the frontal area when viewed from the front, and is formed into a shape imitating a relief-like undulating animal pattern. . The depth 44 of the bulge 41 is smaller than the depth of the bulge 39 and the bulge 62. The bulging portion 41 is a display portion having a large width and a large front area, and is easily visible from the front side. However, since the depth 44 of the bulging portion 41 is shallow, the cross-sectional area of the bulging portion 41 in the width direction is not so large. It does not increase, and thus the internal volume does not increase much.
[0032]
By the way, when the cross-sectional area of the water channel increases and the internal volume of the straw increases, the increased amount of drink water must be sucked up, which may make it difficult for infants to use, so in places where the bulging width in the width direction is increased, Conversely, the depth is reduced so that the cross-sectional area of the channel is not too large. On the other hand, if the depth is too small, the resistance due to the surface tension of the drink increases, and a strong suction force may be required at the time of suction. Therefore, the depth of the portion where the bulging width in the width direction 42 is increased should be appropriately adjusted. Is preferred.
[0033]
In addition, the cross-section reduced portion extending from the upper sheet 28 toward the lower lid 36 is the eye of the animal.
45, nose 46, limbs 47, and neck 50. The drink is difficult to pass through at that point, and the reduced cross-section of the section also serves as a support for stretching to prevent the upper and lower sheets from approaching each other due to the suction pressure and crushing the waterway. In places where there is no support simulating a pattern such as the eyes 45 or the nose 46 and the water channel may be collapsed by suction pressure or external force, apart from the support by the pattern, a substantially small cylindrical cross-section reduction part May be independently provided at any position.
[0034]
The depth 44 of the bulge 41 gradually decreases from the crown 49 to the neck 50 and from the buttocks 51 to the neck 50 of the animal. At a place where the depth 44 is large, the coloration by the drink is dark, and at a place where the depth 44 is small, the coloration by the drink is light. However, at the place where the cross section gradually changes in depth as described above, The color changes gradually, and gradation can be produced.
[0035]
In general, the blister package is provided with a flange portion having an outer shape larger than the bulging portion, and a product name, a desired design, a trademark, an instruction manual, and the like are printed thereon. It is possible to provide a flange portion having an outer shape larger than the bulging portion and provide another display portion on the flange portion. The bulging portion 41 has a flange portion 27 around the periphery thereof for sealing the internal space of the bulging portion 41, and further includes a flange expanding portion 52 which is expanded outward along the same plane of the flange portion 27. In this case, another display portion different from the display portion by the water channel is formed therein.
[0036]
The difference between the flange portion 27 and the flange extension portion 52 in the same plane in the second embodiment is that, for example, at the time of welding such as heat sealing, the joint portion of the flange portion 27 is formed so that the liquid in the water channel does not leak. While the flanges are continuously welded along the periphery of the water channel, the flange extension 52 has a difference in the density of the joints, such as scattered joints, so that the upper and lower sheets are not separated. The distinction may be made, and the density of the joining portions may be the same, and the distinction may not be provided.
[0037]
A notice portion 53 having a bulged outer edge is formed in the flange extension portion 52. The outer edge of the posting portion 53 is a bulging portion 54 having an independent space that is not connected to the space of the water channel, and is formed into a relief-like undulating frame. The printing portion used in combination with the bulging portion 54 forming the frame may be printed on any surface of the upper and lower sheets, and by using the printing together, a luxurious decoration can be produced in both three-dimensional and coloring. In addition, a flat part is provided in the center so that the user can write arbitrary characters and paste a picture, paste a sticker photograph 55 of a person, and further hand-write the personal name "Hikaru". Character 56 is inserted.
[0038]
The three-dimensional character 57, which is a relief-like relief pattern of “happy birthday” formed in the flange extension portion 52, is formed by using an independent bulging portion and printing. The pattern of the flower 58, the musical note 59, and the heart-shaped pattern 60 on the face are displayed only by printing. The upper sheet 28 is directed forward 29 so that the inner space formed by the bulging portion 41 and the inner space formed by the bulging portion 62 communicate with each other in the straw upper portion 61 connected to the upper part of the display portion 40 and having the flange portion 27 around the periphery. The bulged portion 62 is formed by bulging. The bulging portion 62 is a rear opening, extends in the longitudinal direction 38 with a substantially semi-cylindrical cross section, and is formed integrally with the bulging portion 41. Further, a suction port 63 is provided at the upper end thereof for opening the internal space of the bulging portion 62 to the outside.
[0039]
The suction port 63 may have a shape such that the side wall portion 158 of the bulging portion 62 stands upright from the flange portion 27 similarly to the suction port 10 of FIG. 3, but as shown in FIG. The side wall portion 158 between the flange portion 27 and the bulging portion 62 may be smoothly connected via the connecting portion 157. By doing so, when the lip is applied around the suction port 63 to suck the drink, the lip and the bulging portion 62, the connecting portion 157, and the periphery of the flange portion 27 are in close contact with the lip without forming a gap, and the lip is efficiently inserted. You can inhale drinks. When the area around the suction port 63 is easily crushed by the pressure of the lips, a support may be provided by a reduced cross section to increase the strength.
[0040]
In order to form a flexible portion 64 for flexibly bending the straw on the surface of the bulging portion 62 of the straw upper portion 61 and the appropriate length of the peripheral flange portion 27, a relief-like undulating pattern along the width direction 42 is provided. A plurality of peripheral grooves 65 having a substantially V-shaped cross section are formed continuously at appropriate intervals. The substantially V-shaped peripheral groove 65 is formed to extend from the surface of the bulging portion 62 of the semicylindrical shape to the flange 27 at the peripheral portion in the width direction 42 thereof. A substantially V-shaped groove of the flange portion 27 also fits into a flange portion of the lower lid 36 which is joined to face the substantially V-shaped groove formed in the flange portion 27 of the upper sheet 28. A V-shaped groove is formed. Further, the substantially V-shaped groove constitutes a circumferential groove 65 which extends to the entire inner width in the width direction of the lower lid 36 and makes one round. At the time of welding by heat sealing or the like, the substantially V-shaped groove formed in the flange portion is heat-welded in a fitted state.
[0041]
When the transparent sheet is used for at least one of the upper and lower sheets, in printing, an opaque colored pattern or the background may be printed on the entire surface, but the window without the transparent sheet is not printed. May be provided. In FIG. 5, both the upper and lower sheets are made of a transparent material, and the portion of the bulging portion 41 imitating the pattern of the animal is a transparent window without printing on the front and back facing the upper and lower sheets. The change in color due to drinks can be enjoyed from both sides through the transparent window.
[0042]
The printing layer is laminated with one or more films having a desired barrier property so that the printing ink and the remaining solvent do not dissolve into the drink and prevent the outside air and the drink from being mixed into the print layer. May be. If the barrier property of the base film to be printed is insufficient, a film having a desired barrier property may be laminated not only from the front side of the printing layer but also from the back side. The lamination may be performed by laminating a print-compatible film on the layer to be printed and using a heat-seal compatible film on the heat-sealing surface.
[0043]
The flange formed around the bulging portion, which is a communicating space forming the straw portion of the upper sheet, the peripheral groove fitted in the flange, the substantially circular surface 34, etc. By overlapping with the facing portion of the sheet and integrally joining by heat sealing or the like, the opening side of the bulging portion is sealed, the water channel portion can be used as a straw, and the display portion 40 is used together with printing. Thus, the display effect is increased. In FIG. 5, the upper and lower sheets are formed by cutting into the same outer shape, but the outer shapes of the upper and lower sheets may be different. For example, the range of the upper sheet may be up to the flange portion 27, and the display portion of the flange extension portion may be included only in the lower sheet.
[0044]

Embodiment 7 will be described with reference to FIGS. 13 to 15 and FIG. 13 is a perspective view of Example 7, FIG. 14 is a longitudinal sectional view of the straw in the longitudinal direction, FIG. 15 is a transverse sectional view of the display unit near the character “LOVE” 165, and FIG. 20 is an enlarged detail near the upper end of the straw. FIG. In the case of the first embodiment, the bulging portion is a representation of only the relief, and the height of the bulging portion from the flange portion cannot be increased due to the limitation of the flow rate increase. However, in the seventh embodiment, the height 161 of the vertex of the display unit 160 from the flange 159 is higher than the height 162 of the water channel inside the straw, and is substantially cylindrical and greatly bulges upward. ing.
[0063]
If the lower lid 163 remains at the same height as the flange 159, the channel interposed between the upper body 164 and the lower lid 163 has a larger cross-sectional area, and the flow rate of the channel becomes lower. If the user does not increase the suction power of the user, it will be difficult to drink. However, in the display unit 160, the lower lid 163 is greatly curved and swelled so as to contact the lower side of the upper main body 164 so as to follow the swelling of the upper main body 164. Since the water channel having a large height cannot be formed, the flow rate of the drink does not increase, so that no burden is imposed on the user at the time of suction. In addition, since the upper body 164 is largely curved and bulged, the relief pattern can be expressed more three-dimensionally.
[0064]
Near the center of the display section, a letter 165 of "LOVE" is formed in a relief tone. The character portion is molded downward so as to approach the curved lower lid 163 to form a reduced section. Above the display unit, a flexible portion 166 for bending a straw similarly to the second embodiment is configured. Further, although the lower end 167 and the upper end 168 of the straw are closed and formed, perforation lines 169 and 170 are formed, respectively. Thus, a suction port and a suction port that are open to the outside are formed. A substantially V-shaped notch 171 is formed in the flange 159 so that a sharp corner is not formed after the fracture. Normally, conventional straws are packaged in a separate packaging material so that they are not stained.However, by making the opening part closed, even if it is not packaged in a separate packaging material, And virginity is easily maintained. Further, the cost can be reduced because a separate packaging material is not required. Note that a half cut may be used instead of the perforation line.
[0065]
An eighth embodiment will be described with reference to FIGS. FIG. 16 is a perspective view of the eighth embodiment, and FIG. 17 is a longitudinal sectional view in the longitudinal direction. Above the straw 172, there is a display section 173, and the upper sheet of the display section 173 is formed to undulate and bulge in a wave-like manner in the longitudinal direction 174. As in the first embodiment, the bulging molding of the upper body may be performed by bulging forward only from the surface formed by the flange portion 176 of the straight water passage portion below the straw. As described above, there may be a portion that protrudes downward from the surface formed by the flange portion 176.
[0066]
The lower lid 178 below the lower lid 178 is undulated and molded so as to form a continuous water channel following the undulation of the upper sheet. Further, the corrugated flange portion 179 around the corrugated portion is also formed into a corrugated shape in accordance with the undulation of the water channel portion, and the whole is largely undulated, thereby producing an effect of producing a three-dimensional modeling. In the eighth embodiment, both the display portion 173 and the flange portion 179 around the display portion 173 are undulated and undulated, but the shaping by swelling used in the present invention is limited to the above-described embodiment and the display portion. Instead, the whole straw may be freely formed and formed. Inside the display unit, a letter 180 of “LOVE”, which is a reduced section, and a heart-shaped depression 181 are molded in a relief tone. The lower lid 178 may not only function as a lid following the upper main body 175 but also swell to an arbitrary shape so that the lower lid 178 can be viewed and enjoyed from the lower lid side.
[0067]
The ninth embodiment will be described with reference to FIGS. FIG. 18 is an exploded perspective view of the ninth embodiment before heat sealing, and FIG. 19 is a cross-sectional view of the vicinity of the letter “LOVE” 182 on the display unit after assembly and heat sealing. The ninth embodiment has a design similar to that of the first embodiment, except that an upper body 184 and a lower lid 185 are integrally formed via a hinge portion 183 which is a bent portion on one side. 183, the upper body 184 and the lower lid 185 are overlapped at a predetermined position, and flanges facing each other and overlapping are welded by heat sealing or the like.
[0068]
Depending on the thickness and material of the sheet material, even if the cover is folded at the hinge and the cover is closed, the cover may tend to return to the opening direction due to the elasticity of the resin, so the elastic force of the resin may be reduced. In order to weaken and improve the workability at the time of heat sealing, as shown in FIG. 18, a projecting groove 186 over the entire area of the hinge portion 183, or a perforated line penetrating the projecting groove, a half-cut or A plurality of slit holes 187 and the like may be provided. Since the ninth embodiment can be composed of one sheet, it is possible to print both sides of the straw and laminate the barrier of the printed surface only by performing printing and laminating processing on one sheet in advance, thereby reducing cost. Is advantageous.
[0069]
The tenth embodiment will be described with reference to FIGS. FIG. 21 is an exploded perspective view of the tenth embodiment, and FIG. 22 is a cross-sectional view of the display unit in the unfolded state in the vicinity of the “0” character 188. In the tenth embodiment, a hinge portion is attached to the straw of the deformed flange. In the mold at the time of molding, since the height of the flange portion 191 between the upper body 189 and the lower lid 190 is different due to a step, three connecting bands 192 provided on one side each have three positions. It may be formed in a series so that it can be bent via the hinge part 193. Although the lower lid 190 in the display unit 194 is molded three-dimensionally like the upper main body 189, it can be molded simultaneously with one mold, and the mold cost can be reduced. The relief-like undulating pattern of a design, a trademark picture, a character, a pattern, or the like used in the present invention, or printing used in combination, is not limited to the above-described embodiment.
[0070]
【The invention's effect】
The present invention is configured as described above, and has the following effects.
[0071]
By sealing around the bulge formed in a desired outer shape to be the remaining water channel excluding the suction port and the suction port, and forming a blister molded body having an internal space communicating with the bulge. In addition, a straw with an internal space as a waterway is possible. By applying the blister packaging technology, a bulged portion and a flange portion having a relatively large area can be formed. In the case of a large display surface and a small depth of the water channel, the suction pressure causes the front and back surfaces to be attracted to each other and the water channel cross section is easily crushed. As a result, the configuration and maintenance of a large display surface can be achieved.
[0072]
The large display surface is capable of printing desired designs to be used in combination with relief-like undulating patterns such as designs, trademarks, pictures, characters, and advertisements, and by expanding the back cover following the front body, Large modeling of the waterway becomes possible and rich expression can be done. Also, the peripheral flange portion can express printing and other relief-like undulating patterns in the same manner as described above, thereby enriching the expression. In addition, since a flexible portion that does not require a post-process can be made during the same bulging process, the cost can be reduced. In addition, since printing can be performed in advance, such as gravure printing, in the form of a film or sheet before molding, the printing cost can be reduced.
