Description

The present invention relates to a structure of a thick-walled container including a cylindrical container body having an open end and a cylindrical lid having an open end that can be fitted onto one end of the container body to seal the container body. , Thickness for accommodating, storing, and transporting parts for various metal machine tools, especially blades (hobs) of gear cutting machines (hob machines), which are machine tools that cut cylindrical materials into the shape of gears. Regarding the structure of the meat container.

The hob is attached to the hob shaft of a hobbing machine, and a constant rotational motion is applied to the hob and the gear material to perform creative gear cutting, and is used for gear cutting of gears such as spur gears, helical gears, and worm gears. As shown in the photograph of FIG. 1, the hob has blades formed in a spiral shape on the outer surface of a substantially cylindrical shape, and the size varies depending on the size of the material to be processed and the processing content. In addition to being heavy and expensive, it is dangerous to touch it carelessly because many blades are exposed to the outside, and careful handling is required. Therefore, a container made of thick resin as shown in the photograph (non-patent document) of FIG. 2 is used for the storage and transportation. Such existing containers are mainly manufactured as thick-walled containers obtained by blow-molding polytubes.

However, as mentioned above, the size of the hob varies, and if a container that does not fit the size is used, the hob may move inside the container and damage the blade, or the container itself may be damaged. In order to prepare a container, a large number of molds for resin molding must be manufactured, which increases the cost. It is desirable that the lid of the container can be easily opened and closed, but it must be able to be locked firmly so that it will not be easily opened due to an impact during transportation.

The hob container shown in the non-patent document is a thick-walled container composed of a cylindrical container body and a lid, and the lid is fitted onto the container body by screws provided inside the lid and outside the container body. Is rotated and screwed in to close it. Such a hob container has a structure that can firmly fix the lid and the container body, but since the lid must be rotated several times by hand when opening and closing, not only is the workability not always good, but as described above, There is a problem that a large number of molds must be manufactured according to the size of the container, which increases the cost.

The present invention is intended to solve the problems of the prior art, and is a thick-walled container capable of fixing and accommodating containers of various sizes such as hobs, and easily and firmly fixing the lid to the container body. The subject is to provide the structure of.

In order to solve the problem of the preceding paragraph, the structure of the thick-walled container according to claim 1 of the present invention has a cylindrical container body having one end opened and the container body being fitted onto one end of the container body. In a thick-walled container consisting of a cylindrical lid with an open end that can be sealed, the container body has at least a pair of protrusions arranged at least one pair or equidistantly arranged along the axial direction at positions facing the diameter of the outer surface. The lid has at least a pair of grooves at positions facing the diameter of the inner surface thereof, and the grooves have a trunk groove extending in the axial direction from the opening end of the lid and branching from the trunk groove to one side thereof. It consists of a plurality of extending branch grooves, and the lid is locked to the container body by rotating the lid so that the protrusions fitted into the trunk groove from the open end of the lid enter the arbitrary branch groove. It is characterized by making it possible.

The thick-walled container according to the present invention can be manufactured by blow molding of a resin material such as polyethylene, and has a certain elasticity. The total length of the container body is arbitrary, but it is slightly shorter than the assumed total length of the container such as a hob, and the tip of the container is configured to protrude from the open end of the container body.

The lid is opened and closed as follows. When closing, the lid is fitted onto the container body so that the pair of protrusions on the container body fit into each of the pair of trunk grooves that appear at the open end of the lid, and the lid is pushed in the axial direction as it is. Proceed along each trunk groove. Next, when the tip of the container protruding from the open end of the container body comes into contact with the closing surface of the lid, the lid is rotated in the direction of the branch groove, and each protrusion advances along the branch groove. The protrusion stops at the tip of the lid. At this point, the pair of protrusions stop at the ends of the branch grooves at both ends of the diameter of the cylinder, completing the closure. When removing the lid, the lid is rotated in the direction opposite to that at the time of closing, and when the pair of protrusions reach the position of the trunk groove, the lid is pulled out to separate the lid from the container body.

If cushioning materials such as urethane sponge are attached to the inner surfaces of the closed ends of the container body and the lid, both ends of the contained contents are sandwiched and held by the cushioning materials in the closed state of the lid. , Prevents the contents from slipping and moving in the thick container during storage and transportation. Further, when the lid is fitted onto the container body and the tip of the container comes into contact with the closed surface of the lid, the elasticity of the cushioning material causes the lid to be pushed back, so that the lid has a branch groove. By pushing slowly while urging to rotate to the branching side, the protrusion enters the branch groove as soon as the protrusion matches the nearest branch groove, so that the thick container can be easily closed.

Next, the invention according to claim 2 is the thick-walled container according to claim 1, wherein the groove portion is a trunk groove extending in the axial direction from the opening end of the lid and on both sides of the trunk groove. It is characterized by being composed of a plurality of branch grooves extending by alternately branching.

When closing the container body with the lid, slowly rotate the lid to the left and right around the point where the tip of the container protruding from the open end of the container comes into contact with the closing surface of the lid. As soon as the protrusion matches the nearest branch groove on either the left or right side, the protrusion enters the branch groove. In this way, by providing the branch grooves so as to alternately branch and extend on both sides of the trunk groove, the interval between the branch grooves can be made smaller as a whole. As a result, the fixing position of the lid body to the container body can be adjusted more finely, so that it becomes easier to correspond to the total length of the contained object.

Next, the invention according to claim 3 is the thick-walled container according to claim 1 or 2, wherein the branch groove is slightly inclined toward the closed end direction of the lid and branched. It is characterized in that it is configured to do so.

If the branch groove is branched perpendicular to the trunk groove, the lid may inadvertently rotate due to an external force applied to the thick container during transportation, and the protrusion may return to the position of the trunk groove. It cannot be said that there is a risk that the lid will fall off from the container body. When an external force that rotates the lid is applied, if the branch groove is inclined and branched with respect to the trunk groove, the distance between the protrusion and the inner surface of the branch groove is greater than when the branch groove is vertically branched. Since the friction increases, the lid is less likely to loosen, and the risk of the lid falling off can be reduced. The inclination angle of the branch groove can be appropriately set depending on the outer diameter of the thick container, but it is preferably about 5 to 10 ° from the vertical to the trunk groove toward the closed end.

Further, when the cushioning material is provided as described above, the lid is pushed toward the closed end, that is, in the direction away from the container body due to its elasticity. Therefore, if the branch groove is inclined toward the closed end of the lid, An urging force is generated that pushes the protrusion toward the tip of the branch groove. Therefore, when vibration or an external force that rotates the lid is applied to the thick container, this urging works to prevent the protrusions from returning to the trunk groove in the branch groove, and the lid is prevented from falling off. ..

Next, the invention according to claim 4 is the thick-walled container according to any one of claims 1 to 3, wherein the branch groove is provided with a shallow ridge at a position in front of the end portion. It is characterized by that.

By providing a shallow ridge in front of the end of the branch groove, each protrusion traveling in the branch groove is temporarily blocked by the ridge due to the rotation of the lid. However, since the container body has a certain elasticity, each protrusion is pushed into the inside of the container body, gets over the ridge, and stops at the end. At that point, each protrusion is fixed to the end of the branch groove by a ridge. When removing the lid, rotate the lid in the opposite direction so that each protrusion gets over the ridge again and returns to the trunk groove. By providing a ridge in front of the end of the branch groove, the closed lid cannot get over the ridge again unless a rotational force is intentionally applied in the opposite direction, so the lid is carelessly covered by vibration or the like. It prevents the body from loosening and falling off.

Next, the invention according to claim 5 is the thick-walled container according to any one of claims 1 to 4, wherein the container body is made of a plurality of cylindrical bodies that can be cut and separated at a predetermined cuttable portion. Therefore, each cylindrical body is characterized by having at least a pair of protrusions arranged at least one pair or a plurality of pairs of protrusions arranged at equal intervals along the axial direction at positions facing the diameter of the outer surface.

Since the container body is configured by connecting a plurality of cylinders and each cylinder is provided with a protrusion, the open end has the same protrusion even if the container body is cut in the middle and the total length of the container body changes. According to such a configuration, by cutting the container body as necessary, it is possible to handle the contents having different total lengths with one container body.

Next, the invention according to claim 6 is a joint body made of a cylindrical body into which any of the openings at both ends can be fitted onto one end of the container body, and the diameters of the inner surfaces of the openings at both ends are opposed to each other. Each groove has at least a pair of grooves at a position, and each groove is composed of a trunk groove extending in the axial direction from the opening end of the lid and a plurality of branch grooves extending from the trunk groove to one side thereof. The groove is characterized in that a shallow ridge is provided at a position in front of the end portion. By connecting the two container bodies via the joint body having such a configuration, the total length of the thick-walled container can be extended, and it is possible to handle a container having a long total length.

Further, the invention according to claim 7 alternately branches the groove portion of the joint body according to claim 6 into a trunk groove extending in the axial direction from the opening ends of the openings at both ends and from the trunk groove to both sides thereof. The joint body according to claim 8 is composed of a plurality of branch grooves extending in the direction opposite to the opening in the branch groove of the joint body according to claim 6 or 7. The joint body according to claim 9, which is configured to be slightly inclined toward the branch, has a depth at a position in front of the end portion of the branch groove of the joint body according to any one of claims 6 to 8. Each feature is that shallow ridges are provided. As described above, since the joint body connects the two container bodies, the container body is a member corresponding to the lid body of the thick-walled container according to claims 1 to 5, so that the groove portion provided in the joint body is provided. The inclination direction of the branch groove is opposite to that of the opening.

According to the thick-walled container according to the present invention, if a container body and a lid of a standard length are prepared, it is possible to accommodate containers of different lengths, and since different molds are not required, the manufacturing cost. It has a reduction effect. In addition, the lid does not need to be rotated many times, can be easily and firmly fixed with a minimum of movement, and can be easily attached and detached, so that improvement in work efficiency can be expected. Furthermore, the branch groove of the groove is inclined with respect to the trunk groove and branched, and the ridge is provided at a position in front of the end of the branch groove, so that the lid can be easily loosened by an external impact or vibration. Since it does not fall off, it has the effect of safely storing and transporting the contents.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. FIG. 3 is a front view of the container body according to the first embodiment of the thick-walled container according to the present invention, and FIG. 4 is a left side view.

The container body 10 has a substantially cylindrical body body 11 at the left end which is open and the right end is closed, and a regular octagonal prism fringe 12 is provided on the outer peripheral portion at the right end to prevent rolling. Further, the main body body 11 is composed of 11a, 11b and 11c which can be cut and separated at two places. Since the main body 11 can be appropriately cut and separated, the length of the container main body 10 can be changed in three stages according to the total length of the contents. Further, the main body bodies 11a, 11b, and 11c are each provided with three protrusions 13 arranged at equal intervals along the axial direction at 90 ° intervals at positions on the left side of the outer surface, for a total of twelve. Further, a cushioning material 18 is attached to the inner surface of the closed end.

The length of the main body body 11 can be appropriately set according to the total length of the contents, but the longest expected contents are put in, and the lid 14 is fitted to the main body body 11 most deeply by the method described later. In the fixed state, it is desirable to set the length so that there is no gap between both ends of the container and the inner surfaces of both ends of the thick-walled container. This is because such a setting can prevent the contents from moving inside the thick container during storage and transportation. Further, the lengths of the main body bodies 11a, 11b, and 11c, that is, the positions of the two cuttable parts are appropriately set based on the same concept.

5 and 6 are front views of the lid 14a and 14b, respectively, and FIG. 7 is a right side view of the lid 14a (the right side view of the lid 14b is omitted). In both the lid 14a and the lid 14b, the right end of the substantially cylindrical lid body 15 is open, the left end is closed, and the outer peripheral portion of the left end is prevented from rolling by a regular octagonal prism as in the container body 10. A fringe 16 for use is provided. The lid body 14a has a groove portion on the inner surface of the lid body body 15 composed of a trunk groove 17a extending in the axial direction from the opening end and a plurality of branch grooves 17b extending vertically from the trunk groove 17a at equal intervals. 17 is provided. On the other hand, with respect to the lid body 14b, the branch groove 17b branches from the trunk groove 17a at an angle of 5 ° toward the closed end direction. Further, each branch groove 17b ends at the terminal portion 17d, and a shallow ridge portion 17c is provided at a position in front of the terminal portion 17d.

FIG. 8 is a front view of the lid body 14c, and FIG. 9 is a right side view thereof. Like the lid 14b, the branch groove 17b is inclined from the trunk groove 17a toward the closed end at an angle of 5 °, but in the lids 14a and 14b, the branch groove 17b branches only to the upper side of the trunk groove 17a. On the other hand, with respect to the lid body 14c, the branch grooves 17b are alternately branched from the trunk groove 17a to both upper and lower ends thereof.

FIG. 10 is a schematic cross-sectional view of the container body 10 closed by the lid 14c, and FIGS. 11 and 12 are enlarged views of the portions surrounded by circles A and B in FIG. When closing the container body 10 with the lid body 14c, after putting an object (not shown) in the container body 10, the main body is placed in each of the four trunk grooves 17a appearing at the open end of the lid body portion 15. The lid 14c is fitted onto the container body so that the protrusions 13 of the body portion 11a are fitted, and the lids 14c are pushed in the axial direction as they are, so that the protrusions 13 advance along the trunk grooves.

Next, the lid 14c is slightly rotated left and right around the point where the tip of the container protruding from the open end of the container body 10 abuts on the closing surface of the lid 14c to search for the position of the branch groove 17b, and the trunk groove is searched. Of the branch grooves 17b that alternately branch on both sides of 17a, when the lid 14c is rotated in the direction of the branch grooves 17b into which the protrusions 13 can enter, each protrusion 13 advances along the branch grooves 17b. Here, since the shallow ridges 17c are provided in front of the end 17d of the branch groove 17b, each protrusion 13 is once blocked from entering by the ridges 17c, but the main body 11 made of resin. Since each of the protrusions 13 has a certain elasticity, each protrusion 13 is pushed inside the main body portion 11, passes over the ridge portion 17c, and stops at the terminal portion 17d. At that time, each protrusion 13 is fixed to the terminal portion 17d by the ridge portion 17c.

On the other hand, when removing the lid body 14c, the lid body 14c is rotated in the opposite direction, the ridges 17c are made to ride over the ridges 17c on each protrusion 13 again, the lid body 14c is returned to the trunk groove 17a, and the lid body 14c is pulled out from the container body as it is. Can be removed.
