Description

  The present invention relates to a member for preventing misalignment of a confectionery such as a cake and a placing plate structure for a confectionery such as a cake provided with the member.

  Traditionally, cakes are sold in packaging boxes, but in order to prevent the cake from being deformed or broken when the customer transports it, the cake is placed on the packaging box or the cake mounting plate installed at the bottom of the packaging box. A cake lock is installed, and the cake lock is inserted into the cake and fixed.

For example, a thin metal plate (tinplate) lock claw in which a plurality of (three) claws project radially from the outer periphery of the fixed plate at the bottom of the packaging box or the insertion tray is bent upward and obliquely upward. A structure in which a nail pierces the bottom surface of a cake to be placed is known (see, for example, Patent Document 1).
Japanese Utility Model Publication No. 5-32423

  However, the above-mentioned metal cake lock needs to be manually clawed each time the cake is placed, and it is not suitable because it requires time and complicated work in stores and cake packaging lines. The metal cake lock has defects such as wrinkles generated in a high humidity environment, and the wrinkles adhere to cakes, trays, and the like, thereby reducing the value of the product.

In order to eliminate these disadvantages, a tray on which a cake is placed and a pin hole is provided in advance at the bottom, and an insertion support portion that is inserted into the pin hole at the base end portion are formed. None and a lock claw formed by molding a synthetic resin material that protrudes on the bottom surface of the tray in the inserted and fixed state, and when the cake is placed on the tray, the protruding end of the lock claw pierces from the cake bottom surface. A cake lock structure has been proposed (see, for example, Patent Document 2).
Japanese Patent Application Laid-Open No. 8-175583

  However, the lock claws are so-called nails and screws, which are expensive and expensive, and after inserting the lock claws into the tray, the tray must be inserted into the packaging box. It was difficult to install. The cake lock structure is three-dimensionally molded and has a problem that it is bulky during storage and transportation. It is lighter, not bulky, has a small storage space and low transportation cost, and can be easily installed. There has been a demand for a member for preventing misalignment of cakes such as cost cakes.

  In view of the above problems, the object of the present invention is cakes such as cakes that are lightweight, not bulky, have a small storage space, have low transportation costs, are easy to install and low cost, and do not rust during use. An object of the present invention is to provide a misalignment prevention member capable of preventing misalignment and a mounting plate structure using the same.

  The misalignment prevention member of the invention described in claim 1 is a sheet-like member that prevents misalignment of cakes and other confectionery, and is characterized by comprising a stretched polyolefin resin sheet having shape retention.

  As the polyolefin-based resin constituting the stretched polyolefin-based resin sheet, any olefin-based resin having a film forming ability can be used. For example, a high-density polyethylene resin, a medium-density polyethylene resin, a low-density polyethylene resin, a linear low-density Polyethylene resin, polypropylene resin, ethylene-propylene copolymer, ethylene-butene-1 copolymer, ethylene-pentene-1 copolymer, ethylene-hexene-1 copolymer, ethylene-octene-1 copolymer, ethylene -Vinyl acetate copolymer, ethylene- (meth) acrylic ester copolymer, ethylene-vinyl chloride copolymer, ethylene-propylene-butene copolymer, etc., and high-density polyethylene resin is preferably used .

  When the weight average molecular weight of the polyolefin resin is less than 100,000, the polyolefin resin becomes brittle, the stretchability becomes poor, and a stretched polyolefin resin sheet having sufficient strength or creep resistance can be obtained. Conversely, if it exceeds 500,000, the melt viscosity becomes high, the hot melt molding processability is lowered, and it becomes difficult to obtain a uniform sheet, so 100,000 to 500,000 is preferable.

The melt index (hereinafter referred to as MI) of the polyolefin resin is preferably 0.1 to 20 (g / 10 minutes), more preferably 0.2 to 10 (g / 10 minutes), which is excellent in film moldability. is there. MI is an index representing the melt viscosity of a thermoplastic resin specified in JIS K 7210. Furthermore, in the case of a high density polyethylene resin, 0.94 g / cm ³ or more is preferable because the mechanical strength does not improve even if the density is reduced even if the density is reduced.

  The thickness of the polyolefin resin sheet is not particularly limited, but if it is too thick, stretching becomes difficult, and a large pressing force and take-up force are required to crush the polyolefin resin sheet with a rolling roll in the rolling process. In some cases, uniform rolling in the width direction may be difficult due to bending of the rolling roll, and conversely, if too thin, the thickness of the polyolefin resin sheet after stretching or after rolling becomes too thin, and uniform rolling is not possible. Not only is it difficult, but the rolling rolls may come into contact with each other to shorten the life of the rolling roll, so 0.2 to 15 mm is desirable.

  The stretched polyolefin resin sheet only needs to have shape-retaining properties, and the shape-retaining stretched polyolefin system in which the polyolefin resin sheet having a weight average molecular weight of 100,000 to 500,000 is stretched at a stretch ratio of 5 times or more is used. A resin sheet is preferred.

  The draw ratio is 5 times or more, and the drawn stretched polyolefin resin sheet only needs to have shape retention, but the draw ratio is preferably 10 to 40 times. The stretching method may be any conventionally known method, such as a method of stretching while heating with a heater or hot air by a uniaxial stretching method such as a roll uniaxial stretching method or a zone uniaxial stretching method. .

  When stretching uniaxially to a high degree of 10 to 40 times, a multistage uniaxial stretching method in which uniaxial stretching is repeated a plurality of times is preferable. When performing multistage uniaxial stretching, the number of stretching is preferably 2 to 20 times, more preferably 3 to 15 times, still more preferably 4 to 10 times.

  When performing multi-stage stretching by a roll uniaxial stretching method, it is desirable to install a feeding pinch roll, a take-up pinch roll, and at least one, preferably a plurality of contact rolls that rotate at a constant speed between these rolls. By installing such a contact roll, uniform stretchability is improved and stable stretch molding can be performed.

  The contact roll performs uniaxial stretching by applying a frictional force to the polyolefin resin sheet without being pinched. Further, the contact roll may be connected to the feeding roll and / or the take-up roll by a connecting member made of a gear, a chain, a pulley, a belt, or a combination thereof.

  The uniaxial stretching temperature cannot be uniformly stretched when it is low, and the sheet melts and cuts when it is high. Therefore, the range of “melting point−60 ° C.” to the melting point of the polyolefin resin of the polyolefin resin sheet to be stretched is more preferable, It is “melting point−50 ° C.” to “melting point−5 ° C.” of the polyolefin resin.

  Moreover, when extending | stretching highly with a draw ratio of 10-40 times, it is preferable to roll before extending | stretching. The rolling is preferably performed so that the rolling ratio is 5 times or more. Rolling is a method in which a polyolefin-based resin sheet is supplied to a pair of rolls rotating in opposite directions and pressed to reduce the thickness of the sheet and stretch, and the rolled sheet is different from the stretched sheet in that it is an olefin resin. Since it is dense without being oriented, it is highly stretchable.

  When the rolling temperature is lowered, uniform rolling cannot be performed, and when it is raised, the melt is cut. Therefore, the roll temperature during rolling is preferably in the range of “melting point−40 ° C.” to melting point of the olefin resin of the polyolefin resin sheet to be rolled. More preferably, it is “melting point−30 ° C.” to “melting point−5 ° C.” of the olefin resin. In the present invention, the melting point refers to the maximum point of the endothermic peak that accompanies melting of the crystal, which is recognized when thermal analysis is performed with a differential scanning calorimeter (DSC).

  If the applied pressure (linear pressure) applied to the polyolefin resin sheet by the rolling roll is too small, it may not be possible to obtain a predetermined rolling magnification, and conversely if it is too large, not only will the bending of the rolling roll occur, Sliding easily occurs between the rolling roll and the raw sheet, and uniform rolling may be difficult. Therefore, the applied pressure is preferably 100 MPa to 3000 MPa, and more preferably 300 MPa to 1000 MPa.

  When the rolling ratio is less than 5 times, the effect of suppressing necking at the time of uniaxial stretching performed later cannot be obtained, high-strength uniaxial stretching cannot be performed, or the uniaxial stretching step Therefore, it is 5 times or more, preferably 7 times or more. There is no particular upper limit to the rolling ratio, but the higher the rolling ratio is, the more load is applied to the rolling equipment, so 10 times or less is preferable.

  The rolling magnification is defined as (cross-sectional area of polyolefin resin sheet) / (cross-sectional area of polyolefin resin sheet after rolling), but the width of the polyolefin resin sheet hardly changes before and after rolling. (Thickness of resin sheet) / (thickness of polyolefin resin sheet after rolling).

  The rolled polyolefin resin sheet is then uniaxially stretched at a total stretch ratio of 10 to 40 times. As the uniaxial stretching method, any conventionally known method may be employed. Examples thereof include a roll uniaxial stretching method and a zone uniaxial stretching method in which stretching is performed while heating with a heater or hot air.

  When the rolled polyolefin resin sheet is highly uniaxially stretched 10 to 40 times, a method of multistage uniaxial stretching in which uniaxial stretching is repeated a plurality of times is preferable. When performing multistage uniaxial stretching, the number of stretching is preferably 2 to 20 times, more preferably 3 to 15 times, still more preferably 4 to 10 times.

  When performing multi-stage stretching by a roll uniaxial stretching method, it is desirable to install a feeding pinch roll, a take-up pinch roll, and at least one, preferably a plurality of contact rolls that rotate at a constant speed between these rolls. By installing such a contact roll, uniform stretchability is improved and stable stretch molding can be performed.

  The contact roll performs uniaxial stretching by applying a frictional force to the polyolefin resin sheet without being pinched. Further, the contact roll may be connected to the feeding roll and / or the take-up roll by a connecting member made of a gear, a chain, a pulley, a belt, or a combination thereof.

  The uniaxial stretching temperature cannot be uniformly stretched when it is low, and the sheet melts and cuts when it is high. Therefore, the range of “melting point−60 ° C.” to the melting point of the polyolefin resin of the polyolefin resin sheet to be stretched is more preferable, It is “melting point−50 ° C.” to “melting point−5 ° C.” of the polyolefin resin.

  Moreover, since the total draw ratio is 10 to 40 times, the uniaxial draw ratio may be determined so that the total draw ratio is within this range in consideration of the rolling ratio. Is not improved, it is preferably 1.3 times or more, more preferably 1.5 times or more, and still more preferably 1.8 times or more. Moreover, although an upper limit is not specifically limited, 4 times or less are preferable, More preferably, it is 3.5 times or less. The total draw ratio is a value obtained by multiplying the rolling ratio and the uniaxial draw ratio.

  In order to improve the dimensional stability of the stretched polyolefin resin sheet, the stretched polyolefin resin sheet may be annealed at a temperature of the melting point of the polyolefin resin from “melting point−60 ° C.” to the melting temperature or lower.

  If the annealing temperature is lowered, the dimensional stability will not improve, warping will occur if used for a long time, and if it is raised, the polyolefin resin will dissolve and the orientation will disappear and the tensile modulus, tensile strength, etc. will decrease. It is preferable that the resin be annealed at a temperature ranging from “melting point −60 ° C.” to the melting point and below the rolling temperature.

  Annealing is a heat treatment in the production line. When annealing, the stretched polyolefin resin sheet is stretched if a large tension is applied, and it is not stretched or shrinks in a very small state. The length of the stretched polyolefin resin sheet in the stretching direction is preferably kept substantially unchanged, and it is preferable that no pressure is applied to the stretched polyolefin resin sheet. That is, it is preferable that the annealed stretched polyolefin resin sheet is annealed so that the length of the stretched polyolefin resin sheet before annealing is 1.0 or less.

  Accordingly, when the stretched polyolefin resin sheet is continuously annealed while being moved in the heating chamber with a roll such as a pinch roll, the feed rate ratio of the polyolefin resin sheet on the inlet side and the outlet side is 1.0 or less. It is preferable to anneal with setting.

  The heating method at the time of annealing is not particularly limited, and examples thereof include a method of heating with hot air, a heater, a heating plate, hot water or the like. The time for annealing is not particularly limited, and varies depending on the thickness of the stretched polyolefin resin sheet and the annealing temperature, but is generally preferably 10 seconds or more, more preferably 30 seconds to 60 minutes, and still more preferably 1 to 20 Minutes.

  The annealed polyolefin resin sheet may be further aged in a temperature range from 40 ° C. to the melting point of the polyolefin resin. The dimensional stability of the polyolefin resin sheet annealed by aging becomes more excellent.

  Aging is not a continuous treatment in the production line, but it is a relatively long time (minutes, time units) for heat treatment of single-wafers, scrolls, etc., once processed, such as cut winding, of a stretched polyolefin resin sheet. It means to lay down carefully and heat-treat.

  The aging temperature is the same as that left at room temperature when the temperature is low, and when it is high, it is thermally deformed, so the temperature range is from 40 ° C. to the melting point of the polyolefin resin, and the aging time is not effective in a short time and is too long. Even if an effect does not increase, 12 hours-7 days are preferable.

  The stretched polyolefin resin sheet is a sheet obtained by stretching a polyolefin resin sheet having a weight average molecular weight of 100,000 to 500,000 to a stretch ratio of 5 times or more, or after being rolled to a roll ratio of 5 times or more, and then a total stretch ratio. The sheet is uniaxially stretched 10 to 40 times and has shape retainability, but the shape retainability is released after bending the stretched polyolefin resin sheet at 180 degrees and 90 degrees and holding it for 1 minute. The folding return angle θ at 5 minutes after release is preferably 20 degrees or less, more preferably the 180 degree folding return angle θ is 20 degrees or less and the 90 degree folding return angle θ is 20 degrees. More preferably, the 180-degree folding return angle θ is 20 degrees or less and the 90-degree folding return angle θ is 15 degrees or less. If one of the 180 ° and 90 ° folding return angles θ, particularly the 180 ° folding return angle θ exceeds 20 °, sufficient shape retention may not be obtained.

  The thickness of the stretched polyolefin resin sheet is not particularly limited, but is generally 50 to 1200 μm.

  When the sheet-like member is formed of one stretched polyolefin resin sheet, the thickness is generally 200 to 1200 μm, preferably 200 to 1000 μm. In general, a single stretched polyolefin resin sheet is insufficient in mechanical strength. Therefore, it is preferable that a plurality of thin stretched polyolefin resin sheets are laminated. When laminating, it is preferable to laminate 2 to 10 stretched polyolefin resin sheets of 50 to 600 μm, and more preferably 2 to 5. The thickness of the sheet-like member on which the stretched polyolefin resin sheet is laminated is not particularly limited, but is generally 200 to 1200 μm, and preferably 200 to 1000 μm.

  The shape-retaining property of the sheet-like member on which the stretched polyolefin-based resin sheet is laminated is also released when the sheet-like member is bent at 180 degrees and 90 degrees and held for 1 minute, and then released after 5 minutes have passed. Both return angles θ are preferably 20 degrees or less, more preferably 180 degrees bend return angle θ is 20 degrees or less and 90 degrees bend return angle θ is less than 20 degrees, more preferably 180 degrees bend return. The angle θ is 20 degrees or less and the 90-degree folding return angle θ is 15 degrees or less.

  Since it becomes easy to crack when the uniaxial stretching direction of the stretched polyolefin resin sheet is aligned, in order to make it difficult to break, at least one stretched polyolefin resin sheet crosses the uniaxial stretch direction of another stretched polyolefin resin sheet. The crossing angle is preferably 30 to 90 degrees. In particular, it is preferable to laminate a plurality of stretched polyolefin resin sheets so as to intersect each other by 30 to 90 degrees with the uniaxial stretching direction of adjacent stretched polyolefin resin sheets.

  As a method of laminating a plurality of stretched polyolefin resin sheets, any conventionally known method may be employed. For example, a method of bonding with a hot melt adhesive such as polyester, polyolefin, or urethane, a reactive adhesive And a method of bonding with an adhesive such as an epoxy adhesive, a urethane adhesive, a polyester adhesive, or a rubber adhesive.

  The misregistration preventing member of the present invention is a sheet-like member made of a stretched polyolefin resin sheet having the shape retaining property, and the sheet-like member is composed of a fixed portion and a misregistration preventing portion via a bent portion. Since the sheet-like member is held in its shape when bent at the bent portion, the fixing portion is fixed substantially horizontally, and the misalignment prevention portion is used standing upright substantially.

  Next, the present invention will be described with reference to the drawings. FIG. 1 (a) is a plan view showing an example of the misalignment prevention member of the present invention, and (b) is a side view thereof.

Further, the misalignment preventing portion 2 is cut into a substantially triangular shape by being cut from the bent portion 3 so as to become gradually narrower in the direction of the distal end portion. FIG. 1 (c) is a side view showing a use state of the misregistration prevention member shown in FIGS. 1 (a) and 1 (b). The misalignment prevention unit 2 is bent and held along the bent portion 3 so as to be substantially perpendicular to the fixed portion 1. When a cake or other confectionery is placed on this misalignment prevention member, the misregistration prevention unit 2 pierces the cake or other confectionery, and the cake or other confectionery is prevented from being displaced.

  Since the misalignment prevention unit 2 pierces a cake such as a cake and prevents positioning, it is preferable that the tip is sharp so that the tip gradually becomes narrower from the bent part toward the tip. Further, since the sheet-like member is made of a stretched polyolefin resin sheet having a shape-retaining property, it can be easily bent. However, the sheet-like member has a predetermined height at a predetermined position in a direction substantially perpendicular to the fixed portion.

Set to, and then subjected to primary annealing for 7 minutes, followed by secondary annealing in the same manner to obtain an annealed stretched polyethylene resin sheet, which is then fed to a constant temperature bath at 60 ° C. and aged for 24 hours, An aged stretched polyethylene resin sheet was obtained.

Four linear low-density polyethylene resin sheets with a thickness of 60 μm and five obtained stretched polyethylene resin sheets are alternately laminated, and heat-sealed with a 140 ° C. hot press to laminate about 1.2 mm thick. A sheet was obtained. When the obtained laminated sheet was cut into a width of 1 cm and a length of 15 cm, bent at 180 degrees and 90 degrees and held for 1 minute and then released, and the bending return angle θ after the elapse of 5 minutes was measured, They were 5 degrees and 8 degrees, respectively.

The misalignment prevention portion is substantially symmetrical with the first misalignment prevention portion 21 and the second misalignment by the second bent portion 33 formed in the width direction of the sheet-like member at the approximate center of the misalignment prevention portion. It is fractionated by the prevention unit 22. The first misalignment prevention unit 21 and the second misregistration prevention unit 22 are gradually narrowed from the bent portions 31 and 32 toward the second bent portion 33, and the second bent portion 33 has the largest width. It has been made narrower.

  FIG. 9B is a front view showing a use state of the displacement prevention member shown in FIG. The misalignment prevention portion is bent along the second bent portion 33 so that the first misalignment prevention portion 21 and the second misalignment prevention portion 22 overlap with each other, and is substantially perpendicular to the fixing portions 11 and 12. The bent portions 21 and 21 are bent so as to be held. As described above, since the misregistration preventing portion is formed so that the first misregistration preventing portion 21 and the second misregistration preventing portion 22 overlap each other, the strength is high, and the three-dimensional shape is ensured even if the sheet-like member is thin. It is possible to hold it in the position, and the effect of preventing misalignment is high.

  The mounting plate structure according to claim 14 is configured such that the misalignment prevention member according to any one of claims 5 to 13 and the sheet-like or plate-like mounting plate bend the bent portion of the misalignment prevention member. Thus, the misalignment preventing portion is stacked so as to be formed substantially perpendicular to the mounting plate.

  The mounting plate is a sheet or plate for placing cakes or other sweets, for example, paper; synthetic resin such as polyethylene resin sheet, polypropylene resin sheet, polyester resin sheet, polystyrene resin sheet Sheet; Aluminum sheet and the like can be mentioned.

  The misalignment prevention member and the mounting plate may be simply stacked, but it is preferable that the fixing portion is fixed to the mounting plate so that the misalignment prevention member does not move. The fixing method is not particularly limited. For example, an adhesive such as a polyvinyl alcohol-based adhesive, a cellulose-based adhesive, a vinyl acetate-based adhesive, a silicon-based adhesive, or a urethane-based adhesive; a rubber-based adhesive, an acrylic-based adhesive Adhesives such as adhesives, silicone adhesives and urethane adhesives; methods of fixing with adhesives such as hot melt adhesives, methods of fixing with adhesive tapes, and heat-fixing the fixing part to the mounting plate The method of wearing etc. is mentioned.

  FIG. 10 (a) is a front view showing an example of the mounting plate structure of the present invention, and (b) is a front view showing a use state. In the figure, reference numeral 20 denotes a mounting plate, and a displacement prevention member 10 composed of the fixing portion 1 and the displacement prevention portion 2 via the bent portion 3 is a surface of the placement plate 20 (a surface on which cakes or other sweets are placed. ). When used, as shown in (b), the misregistration prevention unit 2 is bent along the bent portion 3 so as to be substantially perpendicular to the mounting plate 20.

  Since the misalignment prevention member 10 has shape retention, when it is deformed as shown in FIG. When a cake or other candy is placed thereon, the misalignment prevention unit 2 pierces the cake or other candy, and the cake or other candy is prevented from being displaced. Therefore, the placing plate structure on which cakes and other sweets are placed can be easily inserted into a container such as a cake box without shifting the position of cakes and other sweets. Will not be displaced and will not break.

  A through hole may be formed in the mounting plate, and a fixed portion or a misalignment prevention portion may be inserted and installed in the through hole. In other words, the fixed portion or the misalignment preventing portion is in contact with the back surface of the mounting plate (the surface opposite to the surface on which the cake or other confectionery is placed) in the through hole formed in the mounting plate, and the positional deviation occurs. The prevention unit may be inserted and laminated so as to be in contact with the surface of the placement plate (the surface on which the cake or other confectionery is placed).

  FIG. 11 is a front view showing another embodiment of the mounting plate structure of the present invention. In the figure, reference numeral 20 denotes a placement plate, and the displacement prevention member 10 has a fixed portion 1 laminated on the back surface of the placement plate 20 (the surface opposite to the surface on which cakes or other sweets are placed). 2 is inserted through a linear through-hole 6 formed in the mounting plate 20 and installed so as to be substantially perpendicular to the mounting plate 20.

  The mounting plate 20 and the misalignment prevention member 10 are inserted into the through-hole 6 formed in the mounting plate 20 by laminating the fixed portion 1 or the misalignment preventing portion 2 and stacked substantially in parallel. The misregistration prevention portion 2 may be formed substantially perpendicular to the mounting plate by bending the bent portion 3 of the prevention member 10, but the misregistration prevention portion 2 by bending the bent portion 3 of the misregistration prevention member 10. Then, the fixing part 1 or the misalignment prevention part 2 may be inserted through the through hole 6.

  Furthermore, the position shift prevention member may be laminated | stacked on the back surface (surface opposite to the surface which mounts cakes, such as cake) in which the through-hole is formed. That is, when used, as shown in FIG. 11, by inserting the misalignment prevention portion of the misalignment prevention member into the through hole formed in the mounting plate and bending the bent portion of the misalignment prevention member. The misalignment prevention unit is installed so as to be substantially perpendicular to the mounting plate.

  The shape of the through hole is not particularly limited as long as it can be inserted through the displacement prevention member. Examples thereof include a straight line shape, a curved shape, and a polygonal line shape. If the misregistration preventing member is a flat surface and the shape of the through hole is curved, broken line, or the like, the misregistration preventing member is difficult to come off. The width of the through hole only needs to be able to be inserted through the misalignment prevention member. The central portion of the through hole may be cut only, and the widths of both ends thereof may be equal to or greater than the thickness of the misalignment prevention member. By rubbing, it becomes difficult for the displacement prevention member to fall off.

  Note that the width of the fixing part or the position error prevention part is larger than the other and larger than the length of the through hole at the boundary between the fixing part and the position error prevention part, and the position error prevention member is inserted into the through hole from the narrow side. If it does so, the boundary of the fixing | fixed part 1 and the position shift prevention part 2 becomes a stopper, and a position shift prevention member can be inserted and fixed to a through-hole with sufficient precision.

  Also, an adhesive such as a polyvinyl alcohol adhesive, a cellulose adhesive, a vinyl acetate adhesive, a silicon adhesive, a urethane adhesive, or the like; a rubber adhesive so that the displacement prevention member does not fall off the mounting plate. Adhesives such as adhesives, acrylic adhesives, silicone adhesives, urethane adhesives; methods of fixing with adhesives such as hot melt adhesives, methods of fixing with adhesive tapes, fixed parts The fixing portion may be fixed to the mounting plate by a fixing method such as a method of heat-sealing to the mounting plate.
