[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvements in packaging packages used for selling, storing, and transporting various foods such as seafood, fruits, prepared foods, vegetables, confectionery, and other desired articles.

[0002]

[Prior art]

 Traditionally, the lid part is integrally connected to one side edge of the container part via a connecting piece part, and when the container part is closed by the lid part, the container part and the lid part A packaging package is known in which the side edges facing the connecting portion are fixed with adhesive tape or stapled. Further, in recent years, as shown in FIG. 13, a lid 103 is continuously connected to one side edge of a container 101 via a connecting piece 102, and the other edge of the container facing the connecting piece 102 is connected. There is also a packaging package in which a locking means composed of a pair of convex portions 201 and concave portions 202 is provided on 101a and the other side edge 103a of the lid body portion and the closed state is maintained by fitting the both. .

[0003]

[Problems to be solved by the device]

 According to the conventional packaging package described above, it is necessary to tape or staple the side edges of the container part and the lid part together while keeping the lid part closed. It takes time and labor, and it becomes necessary to store and manage the adhesive tape, staples, etc. and the packaging package separately. If staples are not secured properly, the needle will fall off and There were various problems such as the possibility of being mixed in the department. Further, the packaging package shown in FIG. 13 is integrally provided with the locking means for maintaining the closed state by the lid body portion 103, so that the locking means using the adhesive tape or the stapler is not necessary and the conventional technology is not provided. Although it is possible to eliminate the drawbacks it possesses, a closer examination of its technical contents revealed the following drawbacks.

That is, according to the locking means by fitting the pair of protrusions 201 and the recesses 202 described above, the direction of releasing the engagement is the same as the direction of opening the lid body 103. For example, if the contents (packaged items) are relatively bulky and stress acts in the direction of pushing up the lid 103, the protrusion 201 and the recess 202 are disengaged and the lid 103 is opened. There is a risk of leaving. Therefore, while sufficient locking force is required to prevent such a situation from occurring, a large pressing force is required when inserting the convex portion 201 into the concave portion 202, and the convex portion 201 is pushed from the concave portion 202. Since the same force was required when pulling out, the lid closing and opening operations were troublesome. In addition, if the protrusion 201 is not inserted (press-fitted) sufficiently, the locking force of the lid 103 is immediately reduced, so that high precision is required during the lid closing work, and it can be said that the packaging work can be significantly improved. It was difficult. Also, with this locking means, it is inevitable to hold down the bottom surface 202a of the concave portion when inserting the convex portion 201, but this type of packaging package generally uses a synthetic resin sheet such as APET, PS, PVC or the like. Along with the fact that the lid body 103 is integrally formed into a thin shape with a thickness of 1 mm or less, the bottom surface 202a of the recessed portion is crushed when the lid 103 is frequently opened and closed, and a predetermined locking force cannot be obtained.

The present invention has been made in view of such a conventional situation, and an object thereof is to provide a roller integrally with a locking means for holding a closed state by a lid body, and to achieve the above-mentioned conventional. In addition to solving various problems of the packaging package, the engagement release direction of the packaging package is different from the opening direction of the lid body, as compared with the conventional technique using the engagement means. To provide a novel packaging package that can perform the lid closing work and the lid opening work more easily and can maintain the initial engaging force even if the lid body is opened and closed frequently. is there.

[0006]

It is characterized in that it is formed in a substantially trapezoidal cross-sectional shape that is slidably engaged.

Further, according to a third aspect of the present invention, a lid body portion for opening and closing the container portion is integrally connected to one side edge of the container portion having a substantially rectangular shape in plan view via a restoring piece having a restoring property. In addition, an engaging portion is provided on one of the other side edge of the container portion facing the connecting piece portion and the other side edge of the lid portion, and the engaged portion engages with the engaging portion on the other side. And a fitting hole into which the engaging portion is fitted, and an engaging portion that is provided along the other side edge and is continuous with the fitting hole, and is fitted into the fitting hole. A lock groove for locking the engaging portion by sliding the engaging portion, and the engaging portion has a substantially inverted truncated cone shape in which the head portion is enlarged with respect to the base end portion, and the locking portion is provided. The groove is formed into a substantially trapezoidal cross-sectional shape in which the engaging portion is slidably engaged, and the lock groove further includes a lid portion to define the container portion. The engaging portion is provided at a position where the engaging portion is locked in the closed state, and the engaging hole is engaged with the engaging portion when the lid body is deformed laterally from the closed state. It is characterized in that it is provided in a position.

[0009]

[Action]

 According to the structure of claim 1, the lock groove closes the engaging portion by closing the lid portion and sliding the engaging portion fitted in any of the fitting holes to the side (lock groove direction). The locked state of the container body is maintained by the lid body and the engaging portion in the lock groove is slid toward the fitting hole to release the lock of the engaging portion by the lock groove. As a result, the maintenance of the closed state is released. In other words, the direction in which the lock groove unlocks the engaging part is a direction that intersects the lid part opening direction almost vertically, and the lid part in the closed state is pushed up. Even if a stress acts, there is no possibility that the stress directly acts as a disengagement between the lock groove and the engaging portion. Therefore, the lid body portion can be securely locked with a small locking force as compared with the locking means in which the direction of releasing the engagement between the engaging portion and the engaged portion is the same as the opening direction of the lid body portion. It becomes possible to do. Further, the sliding of the engaging portion with respect to the lock groove is performed by the operation of sliding the lid body sideways, so that the fitting hole, the lock groove, and the engaging portion are crushed during the sliding operation. There is no risk of stress.

According to the second aspect of the present invention, the engagement portion is locked by the lock groove by engagement between the engagement portion having a substantially inverted truncated cone shape and the lock groove having a substantially trapezoidal cross section. Therefore, the sliding of the engaging part with respect to the lock groove is made smoother, and at the same time, when a stress acts in the direction of pushing up the lid body part in the closed state, the stress causes the engagement between the engaging part and the lock groove to be further increased. It becomes stronger, and it becomes possible to more reliably maintain the closed state of the lid body.

According to the third aspect of the present invention, the lid portion is closed against the resilience of the connecting piece portion, and the lid portion is closed against the container portion against the resilience. The engagement part is fitted into the fitting hole by deforming from the position to the side, and then the lid part is returned to the position where the container part is closed, and the engagement part in the fitting hole is moved to the side (lock groove). The locking groove locks the engaging part by sliding the lid part in the direction) so that the lid part maintains the closed state of the container part. Therefore, in addition to the effects obtained by the above-mentioned claims 1 and 2, due to the resilience of the connecting piece, a stress is always exerted in the direction of pushing up the lid body portion in the closed state, and the stress causes the engagement portion and the lock groove. In addition to the stronger engagement with, the locking of the engaging part will not be released unless the lid part is laterally deformed against the restoring property of the connecting piece part. It is possible to maintain it reliably.

【Example】

 Examples will be described below. In FIG. 1 to FIG. 8, a lid body portion 3 for opening and closing the body portion 1 is integrated with one side edge 1a of the body portion 1 having a substantially rectangular shape in a plan view via a connecting piece portion 2 having resilience. The engaging portion 4 is provided on the other side edge 1b of the container portion that is connected to the connecting piece portion 2 and the engaging portion 4 engages with the other side edge 3a of the lid portion 5. A packaging package a provided with is shown. The packaging package a is a well-known material used in this kind of technical field, for example, APET (non-stretched amorphous PET sheet), PS / OPS (polystyrene biaxially stretched sheet), PVC (polyvinyl chloride resin). A synthetic resin material such as is used to integrally form the above-mentioned container part 1, connecting piece part 2, lid part 3, engaging part 4, engaged part 5, etc. In addition to having the properties and water resistance, the connecting piece portion 2 is given a predetermined restoring property. Further, the container portion 1 and the lid portion 3 are provided with reinforcing ribs (shown) and ventilation holes (not shown) at a plurality of locations as appropriate to improve their strength resistance.

The engaging portion 4 is located on one side in the longitudinal direction of the pedestal surface 6 formed by expanding the substantially central portion of the other side edge 1b of the container 1 toward the inside of the container 1 (FIG. 1, FIG. In FIG. 4, it is composed of a protrusion protruding toward the right side. More specifically, the cross-sectional shape of the other side edge 1b along the width direction is shown in FIG. In addition to having an enlarged substantially inverted truncated cone shape, the cross-sectional shape of the other side edge 1b along the length direction is substantially cylindrical as shown in FIG.

The engaged portion 5 expands a substantially central portion of the other side edge 3 a of the lid body portion 3 toward the inside of the lid body portion 3, and when the lid body portion 3 is closed, the pedestal is formed. A pedestal surface 7 opposite to the surface 6 is formed, and the pedestal surface 7 is formed with a fitting hole 5a into which the engaging portion 4 is fitted, and a fitting hole 5a provided in series with the fitting hole 5a. By sliding the engaged engaging portion 4 laterally, a locking groove 5b for locking the engaging portion 4 is provided as a recess.

The fitting hole 5a has an inner diameter that allows the engagement portion 4 to be loosely fitted therein, and is located closer to one side in the longitudinal direction of the pedestal surface 7 (toward the left side in FIGS. 1 and 2). ), The lid portion 3 is provided at a position where the engaging portion 4 fits in the state where the container portion 1 is deformed to the side from the closed state.

The lock groove 5b has a sectional shape in which the engaging portion 4 is slidably engaged, that is, a substantially trapezoidal shape in which a bottom portion 5b-2 expands with respect to an opening edge portion 5b-1 as shown in FIG. It is provided so as to extend along the other side edge 3a of the lid body with the cross section of. The lock groove 5b is located closer to the other side in the longitudinal direction of the pedestal surface 7 (closer to the right side in FIGS. 1 and 2), and more specifically, as shown in FIG. It is provided at a position where the engaging portion 4 is locked in the state.

The procedure of using the packaging package a of the present embodiment having the above-described configuration will be described. First, the object to be packaged was placed in the container portion 1 in the open state due to the restoring property of the connecting piece portion 2. After that, the lid 3 is closed against the resilience of the connecting piece 2, and the lid 3 is deformed laterally from the position where the container 1 is closed against the resilience. The engaging part 4 is fitted into the fitting hole 5a (see FIG. 7 (a)), and then the lid part 3 is returned to the position where the container part 1 is closed, and the engaging part inside the fitting hole 5a. 4 is slid in the direction of the lock groove 5b, the lock groove 5b locks the engaging portion 4, whereby the lid portion 3 keeps the container portion 1 closed (see FIG. 7B). . Further, when opening the lid part 3, the engaging part 4 in the lock groove 5b is slid toward the fitting hole 5a while the lid part 3 is laterally deformed against the restoring property of the connecting piece part 2. By doing so, the lock of the engagement portion 4 by the lock groove 5b is released, and the maintenance of the closed state is released (see FIG. 7A).

According to such a locking structure, the unlocking direction of the engaging portion 4 is a direction substantially perpendicular to the opening direction of the lid portion 3, and the lid portion is in the closed state. Even if a stress acts in the direction of pushing up 3, the stress is not likely to directly act to unlock the engaging portion 4. Therefore, as compared with the locking means (the locking means shown in FIG. 13) in which the direction of releasing the engagement between the engaging part and the engaged part is the same as the direction of opening the lid part, the locking force is smaller. Therefore, the lid body portion 3 can be securely locked, and the lid closing work and the lid opening work can be performed more easily and smoothly. Moreover, if the engaging portion 4 is inserted into the lock groove 5b, a predetermined locking force can be surely obtained, so that high precision is not required at the time of the lid closing work, and the packaging work becomes extremely easy. The sliding of the engaging portion 4 with respect to the lock groove 5b is performed by the operation of sliding the lid portion 3 to the side, so that the fitting hole 5a, the lock groove 5b, and the engaging portion 4 are slid during the sliding operation. There is no risk of crushing stress, and a stable locking force can be maintained for a long time even if the lid 3 is opened and closed frequently.

Further, in the lock groove 5b, as shown in FIG. 8, the engagement portion 4 having a substantially inverted truncated cone shape matches the lock groove 5b having a substantially trapezoidal cross section, and the lock groove 5b locks the engagement portion 4. As a result, the closed state of the body portion 1 by the lid portion 3 is maintained. In this state, due to the resilience of the connecting piece portion 2, stress always acts in the direction of pushing up the lid portion 3, but due to the response force, the engagement between the engaging portion 4 and the lock groove 5b is further strengthened, and the connection is made. Unless the lid portion 3 is deformed laterally against the stability of the piece portion 2, the engagement portion 4 cannot be unlocked, so that the lid portion 3 can be more reliably maintained in the closed state. Will be possible.

Next, another embodiment in which a part of the packaging package a described above is modified will be described with reference to FIGS. 9 and 10, but the same components as those described above in these embodiments will be described.

In this embodiment, two left and right ends of the other side edge 1b of the body portion 1 are expanded toward the inside of the body portion 1 to form pedestal surfaces 6 and 6, and one side of each pedestal surface 6 in the longitudinal direction. Protrusions are provided on the side (on the right side in FIG. 10) to form the engaging portions 4 and 4. On the other hand, the two left and right ends of the other side edge 3a of the lid body 3 are expanded toward the inside of the lid body 3 and when the lid body 3 is closed, they face the pedestal surfaces 6 and 6, respectively. The pedestal surfaces 7, 7 facing each other are formed, and the fitting holes 5, 5 are formed in the respective pedestal surfaces 7 to form the engaged parts 5, 5.

Further detailed shapes of the engaging portion 4 and the engaged portion 5 in the respective packaging packages a ₁ and a ₂ , and the positional relationship between the fitting hole 5a and the lock groove 5b with respect to the engaging portion 4. Further, the operation and effect of the locking structure and the procedure of using the packages a1 and a2 are the same as those described above, and therefore, the description thereof is omitted here. According to these packages a ₁ and a ₂ , since the locking portion 4 and the locked portion 5 are provided at two places on the left and right, it is possible to maintain the lid body 3 in the closed state extremely reliably and firmly. Therefore, it is more useful when used, for example, in the case where the upper surface of the content (the object to be packaged) projects from the container portion 1 or in the case where the content is heavy.

11 and 12 show modified examples of the engaged portion 5 in each of the above-described embodiments. The engaged portion 5'shown in FIG. 11 has fitting holes 5a, 5a provided at the left and right ends of the lock groove 5b in a concatenated manner. After the body part 3 is deformed in any direction to the left and right to fit the engaging part 4 into the fitting hole 5a on either side, the engaging part 4 is slid in the direction of the lock groove 5b. Is locked, and the closed state of the lid 3 is maintained. When opening the lid portion 3, the lid portion 3 is deformed in any direction to the left and right, and the engaging portion 4 is slid in the direction of one of the fitting holes 5a to lock the engaging portion 4. To cancel. Therefore, there is an advantage that the locking direction and the unlocking direction of the engaging portion 4 can be arbitrarily selected from the left and right directions.

The engaged portion 5 ″ shown in FIG. 12 is formed by intersecting the above-mentioned lock groove 5 b in a cross shape in a plan view, and the fitting holes 5 a are connected to the respective outer end portions of the lock groove 5 b. When this engaged portion 5 ″ is adopted, after the lid portion 3 is deformed in any direction up, down, left or right and the engaging portion 4 is fitted into any of the fitting holes 5 a. By sliding the engaging portion 4 in the direction of the lock groove 5b connected to the fitting hole 5a, the engaging portion 4 is locked and the closed state of the lid 3 is maintained. Further, when opening the lid portion 3, the lid portion 3 is deformed in any direction up, down, left, right, and the engaging portion 4 is slid in the direction of any of the fitting holes 5a to unlock the engaging portion 4. . Therefore, there is an advantage that the locking direction and the unlocking direction of the engaging portion 4 can be arbitrarily selected from four directions of up, down, left and right.

In each of the packaging packages a, a ₁ and a ₂ described above, the engaging portion 4 is provided on the right side and the fitting hole 5a is provided on the left side, and the engaging portion 4 is provided on the container portion 1 side. Although the provided engaged portion 5 is provided on the lid portion 3 side, conversely, the engaging portion 4 is provided on the left side and the fitting hole 5a is provided on the right side, or the engaging portion 4 is provided. Needless to say, even if the engaged portion 5 is provided on the lid portion 3 side and is provided on the container portion 1 side, the same action and effect as described above can be obtained. Further, in each of the embodiments, the case 1 has been described as having a substantially rectangular shape in plan view, but the present invention is not limited to this, and the case may have a substantially square shape, a substantially elliptical shape, or a substantially circular shape in a plan view. It goes without saying that it is also applicable to things such as. Further, even if the connecting piece portion 2 does not have a restoring property, it is sufficiently possible to achieve the initial purpose.

[Effect of device]

 Since the packaging package of the present invention is configured as described above, it has the effects described below. According to the packaging package of claim 1, the direction of releasing the lock of the engaging portion by the lock groove is a direction substantially perpendicular to the direction of opening the lid portion, and the lid body is in the closed state. Even if a stress acts in the direction of pushing up the portion, there is no possibility that the stress directly acts as a disengagement between the lock groove and the engaging portion. Therefore, compared with the locking means in which the direction of releasing the engagement between the engaging part and the engaged part is the same as the direction of opening the lid part, the lid part is securely locked with a small locking force. It is possible to perform the lid closing work and the lid opening work more easily and smoothly. However, if the engaging portion is inserted into the lock groove, a predetermined locking force can be surely obtained, so that high accuracy is not required at the time of the lid closing work, and a great improvement in the packaging work can be expected. Further, since the engagement portion is slid with respect to the lock groove by sliding the lid body sideways, there is a stress such that the fitting hole, the lock groove and the engagement portion are crushed during the closing and opening operations. There is no danger of working. Therefore, a stable locking force can be maintained for a long period of time even if the lid part is frequently opened and closed, which is convenient because it can be repeatedly used as a storage case after purchase. Since the locking means for maintaining the closed state of the lid body is integrally provided, the packaging work is significantly improved and the adhesive tape and Needless to say, there is no need to separately store and manage the staples and the like, and there is no risk that the staples will be mixed in the body part, so that there is an excellent safety effect.

According to the packaging package of the second aspect, the sliding of the engaging portion with respect to the lock groove can be made smoother, and at the same time, stress acts in the direction of pushing up the lid body portion in the closed state. With the stress, the engagement between the engaging portion and the lock groove is further strengthened, and the closed state of the lid can be more reliably maintained. Therefore, the above-mentioned effect according to claim 1 can be made more effective.

Further, according to the packaging package of the third aspect, in addition to the effects obtained by the first and second aspects described above, the lid of the lid body portion is closed by effectively utilizing the resilience of the connecting piece portion. Since the state can be maintained more reliably, the workability at the time of closing and opening the lid is excellent, the durability against repeated use is also high, and the closed state of the lid body is more surely maintained. As a reliable package can be provided.
