- the bottom seal portion 13 is formed in a ridge shape having a height and width, so that the crimping area between the outer layer 2 and the inner layer 3 in the bottom seal portion 13 is increased, and a plurality of chamfered portions 16 are provided.
- the resistance against shearing force parallel to the crimping surface, which is forced by force is dramatically increased, which makes it difficult for bottom cracks to occur. It is possible to obtain the bottom seal portion 13 with high strength. Disclosure of the invention
- the plurality of biting portions 16 are provided, so that the pressure-bonding area between the outer layer 2 and the inner layer 3 in the bottom seal portion 13 is increased.
- the peel strength between the pair of rib pieces 14 obtained is not necessarily sufficient, and the peel strength between the pair of rib pieces 14 in the bottom seal portion 13 is not sufficient. There is a strong demand for further strengthening.
- the present invention was devised to solve the above-described problems in the prior art, and the bottom rib of the bottom seal portion formed by cutting out the bottom portion of the blow-molded delaminated plastic container.
- the technical problem is to increase the peel resistance of the pair of rib pieces that make up the product, and it is intended to strongly prevent the occurrence of bottom cracks in the laminated peelable plastic container and to maintain a good use condition stably. To do.
- the bottom seal portion of the bottom portion that is crushed flat by the pinch-off portion of the blow mold and formed by cutting is formed of a bottom rib formed into a ridge shape by superposing and crimping a pair of rib pieces.
- Blow metal that molds the bite into the hole near the bottom of the bite. Providing a bulge that bulges at a height within the range that allows forcibly removing the pin of the mold,
- the bottom seal portion formed by the bottom rib formed by superposing and pressing the pair of rib pieces into a protrusion shape has an outer layer, an inner layer,
- the wall structure is laminated in the order of the inner layer and the outer layer, and since it has a ridge structure having a height and width, it has a large crimping area, which makes the outer layer and the inner layer less compatible with each other. It is possible to obtain a high pressure bonding strength even between the two.
- the biting portion formed in the bottom rib has a structure in which one rib piece force bites into the other rib piece, and the overlapping surface of the outer layer and the inner layer in the bottom rib is concave and convex at this biting portion.
- the polymerization area is increased and the pressure bonding strength is increased, and the resistance against the shearing force parallel to the main portion of the pressure bonding surface is increased.
- biting portion is formed by local pressing deformation of the bottom rib due to strong pressing force
- a strong pressing force acts on the bottom rib portion in the vicinity of the biting portion, so that the outer layer and the inner layer in the biting portion are strongly pressed, and a strong pressing strength is exhibited.
- the grease material positioned around the biting portion is a portion positioned facing the bulging portion.
- the squeezing portion functions as an undercut that squeezes in the peeling direction of both rib pieces, and thus strongly prevents peeling of both rib pieces.
- the invention according to claim 2 is a configuration in which the bulging portion is provided only on the upper side of the biting portion in the configuration of the invention according to claim 1.
- the bulging portion is formed only on the upper side of the biting portion, the bulging height of the bulging portion can be sufficiently increased.
- the invention described in claim 3 is obtained by adding the crimping part, which is the bottom part of the biting part, to the sufficiently thin plate shape in addition to the invention described in claim 1 or 2.
- the crimping portion which is the bottom portion of the biting portion is a flat plate having a sufficiently thin shape, the resin molded into the crimping portion. It is possible to apply a sufficiently strong pressing force to the material, and this pressing force is effective as a pressing force on the pressing surface between the outer layer and inner layer of the resin material formed in the pressing part. Work powerfully.
- the bottom seal portion hardly shrinks during cooling and hardening, and even if the shrinkage deformation force acts on the surrounding force, this deformation force Is absorbed as stagnation deformation of the entire crimping part, thereby preventing the occurrence of peeling at the crimping part.
- the invention according to claim 4 is obtained by adding the bulging portion to the bottom portion of the biting portion in addition to the invention according to claim 3.
- the size of the crimping portion of the biting portion can be increased by an amount corresponding to the bulging portion of the bulging portion without significantly increasing the volume of the biting portion.
- the invention described in claim 5 is the same as the invention described in claim 1, 2, 3 or 4, except that the biting portion is formed in a laterally long and oval shape.
- the pressure-bonding portion of the biting portion is also horizontally long, and the size of the pressure-bonding portion is reasonably large, and the upper and lower sides along the overlapping surface of the pair of rib pieces. Since the wide hole wall faces the shearing force acting in the direction, it exerts a strong resistance against this shearing force.
- the invention described in claim 6 bites into the configuration of the invention described in claim 1, 2, 3, 4 or 5.
- the upper part has two rows in a staggered pattern.
- the biting portion is provided over the entire width range of the bottom rib along the parting line without forcibly reducing the interval between the biting portions adjacent in the lateral direction. It can arrange
- biting portions are alternately positioned on the opposite side with respect to the main portion of the crimping surface, the plurality of biting portions cause both rib pieces to squeeze on both sides of the main portion of the crimping surface. This structurally enhances the coupling between both rib pieces.
- the overlapping surface force between the outer layer and the inner layer of the bottom rib is uneven, which increases the polymerization area and increases the bonding strength.
- the resistance against the shearing force parallel to the main part of the is increased.
- a constricted portion that is curved in an undercut shape with respect to the peeling direction of the two rib pieces is formed.
- the mating portion functions as an undercut that fits in the peeling direction of both rib pieces, thus strongly preventing the peeling of both rib pieces and thereby preventing the occurrence of bottom cracks.
- the thickness of the crimp portion of the erosion and recess is sufficiently small! /, So that the laminated structure of the outer layer and the inner layer is hardly affected by the shrinkage deformation force at the time of cooling and hardening. Maintains a stable and strong state, thereby maintaining a strong crimped state stably.
- the bottom seal portion can be increased without reducing the overall mechanical strength.
- the size of the crimping portion of the biting portion can be increased without difficulty, and the shearing force acting in the vertical direction along the overlapping surface of the pair of rib pieces.
- the wide hole wall surface is opposed to each other, a strong resistance against the shearing force is exhibited, whereby a stronger resistance against the bottom crack can be exhibited.
- biting portions can be arranged almost uniformly over the entire width range of the bottom rib along the parting line, the entire width of the bottom rib can be arranged.
