Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a lid constituting a container for storing engraved vegetable salad, cooked buckwheat, udon, etc., and particularly to a lid capable of integrating a synthetic resin knife, fork or the like. Is.
[0002]
[Prior art]
In recent years, it is a common practice to pack vegetable salad or the like in a packaging container and take it home as is. In addition, the packaging containers used in this way are mass-produced from a synthetic resin sheet material as an integrated and sanitary product, and various shapes have been proposed.
[0003]
Also, in this type of packaging container, as described in the prior art section of Japanese Patent Laid-Open No. 6-255665, a fork, a spoon, and the like are integrated on the lid side. For example, the opposing portions above the inner wall surface of the lid are formed in a concavo-convex shape so as to provide a spoon locking portion.
And the invention proposed in the above-mentioned JP-A-6-255665 is as follows:
“To provide a container lid provided with a spoon locking structure that can be easily attached and detached stably due to elastic deformation of the locking piece and that does not affect the shape of the lid body. For the purpose of
“A spoon structure is configured with at least a pair of locking portions provided at arbitrary positions of the lid body, and one or both of the pair of locking portions are formed by providing a desired slit between adjacent ones. It is composed of an elastic locking piece ”.
[0004]
However, it is not preferable to form a “slit” to lock the spoon because the stored item is a food product. There are also problems.
[0005]
Furthermore, neither the invention proposed in the above-mentioned Japanese Patent Application Laid-Open No. 6-255665 nor the invention shown in the prior art section of this publication is a problem at all. The so-called “blocking” is a problem that arises when actually used. Blocking means that when many of the same container body and lid are stacked, they are overlapped because each other has the same shape.
[0006]
In order to avoid this blocking, bulging protrusions are usually formed on a part of the lid or the like, and the location of these bulging protrusions is changed for each lid. These bulging protrusions are formed so as to be as low as possible so as not to form a useless space more than the space necessary for preventing blocking when a large number of lids are stacked. Is done. Therefore, if the engaging protrusion for locking a fork, spoon, etc. is formed ignoring the height of the bulging protrusion, the bent bulging protrusion may not have any meaning. This may cause the fork to be locked.
[0007]
[Problems to be solved by the invention]
The present invention has been made in view of the above circumstances, and an object of the present invention is a lid that constitutes a packaging container, in which a fork and the like are integrated. And the like is performed so as not to affect the function of the bulging protrusion for preventing blocking.
[0008]
That is, the object of the present invention is to provide a packaging container capable of easily and reliably locking a fork or the like and not adversely affecting the function of the anti-blocking protrusion. It is to provide a lid.
[0009]
[Means for Solving the Problems]
In order to solve the above problems, means taken by the present invention will be described with reference numerals used in the embodiments described below.
“It is a lid 10 that is fitted into an opening of a container main body that stores a storage object and is integrally formed of a synthetic resin sheet in order to cover the container main body,
The lid 10, two of the bulge portion 1 1 even without least the exit formed bulging while facing each other on the upper surface, a projection 12 for antiblocking that bulges molded around the respective bulging portions 11, lower Oh have channel forming portion 13 from the upper surface of the bulging portion 11, each pair oriented portions of these respective Airo forming portion 13 and an engagement recess 14 for locking the fork 20 is integrally formed those having and be Rutotomoni,
The height of the engaging recess 14 from the upper surface of the lid 10 is substantially the same as or lower than the height of the protrusion 12 ”
It is.
[0010]
That is, the lid body 10 according to the present invention is integrally formed of a synthetic resin sheet, and the gap forming portion 13 is bulged and formed on the opposed surfaces of at least two bulged portions 11 formed to face each other. In addition, the fork 20 is locked by the respective engagement recesses 14 formed at the distal end portions of the respective gap forming portions 13. Then, the lid 10, the height from the upper surface of the lid 10 of the engagement recess 14, or substantially the same as the impact force 12 that is formed for blocking prevention and the less Is.
[0011]
By forming the lid body 10 as described above, the pair of engagement recesses 14 formed at the distal end portion of each gap forming portion 13 support the handle for the fork 20 in particular as shown in FIG. As a result, the fork 20 can be easily integrated with the lid 10. The fork 20 can be engaged with the respective engagement recesses 14 by the following two methods.
[0012]
As shown in FIG. 1, the first engagement method is a method in which the handle of the fork 20 is forcibly pushed from above into the gap forming portions 13. Since the lid body 10 is integrally formed of a synthetic resin sheet, each gap forming portion 13 has sufficient flexibility to force engagement, and each engagement recess is formed. Since the place 14 has sufficient elasticity to return to the original position, the fork 20 can be easily engaged between the respective passage forming portions 13 and the fork 20 can be easily connected to each other. The engaged state is sufficiently maintained.
[0013]
The second engagement method is a method in which the tip of the fork 20 is slid on the upper surface of the lid 10 and inserted between the respective passage forming portions 13. In this method, as shown in FIG. 1, the place where the fork 20 is to be attached is clarified by the two bulging portions 11, and literally an “airway” is formed by each airway forming part 13. In addition, it is possible to easily insert the gaps between the gap forming portions 13 for locking the forks 20 and to smoothly carry out without applying an excessive force to the tip of each of the gap forming portions 13. It can be done.
[0014]
In adopting the second method, in the lid body 10 of the embodiment, the side surface of each air passage forming portion 13 is formed in an arc shape. It becomes a guide surface, and the locking operation between the respective engagement recesses 14 of the fork 20 can be performed without difficulty. Of course, it goes without saying that in order to remove the fork 20 from the lid 10, an operation reverse to that described above may be performed.
[0015]
By the way, before the lid 10 is fitted into the opening of the container body (not shown), for example, as shown in FIG. 2, a large number of objects are stacked, that is, stacked. In order to prevent blocking, a plurality of protrusions 12 are provided, and these protrusions 12 allow the lids 10 to be stacked at a predetermined interval. At this time, if the engagement recess 14 is formed at a position higher than the rear surface of the protrusion 12, not only the presence of each protrusion 12 becomes worthless, but also depending on the height of each protrusion 12. Although the dead space between the lids 10 at the time of stacking is set to be minimal, the engagement recess 14 formed at a position higher than the top surface of the protrusion 12 causes a large gap between the lids 10. A dead space will be formed.
[0016]
In that respect, in the lid body 10 of the present invention, the height of each engagement recess 14 is set to be substantially the same as or less than that of the projection 12, so that dead time when stacking a large number of lid bodies 10 is achieved. The generation of space can be suppressed. Therefore, when a large number of the lids 10 are packed together, not only can the operation be performed reliably, but also the volume of the bag or box for packing can be reduced.
[0017]
In particular, in the lid body 10 of the present invention, the upper surface of the opening forming portion 13 is an inclined surface 13a that reaches the engagement recess 14 side, so that as shown in FIG. Since the end portion of the portion located between the path forming portions 13 can be brought into contact with the inclined surface 13a of the air path forming portion 13 constituting the lower lid 10, the dead space at the time of stacking can be reduced. The generation can be suppressed as much as possible.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
The present invention configured as described above will be described in detail as follows with respect to the lid body 10 according to the embodiment shown in the drawings. The lid 10 covers an opening of a container main body (not shown) and constitutes a packaging container together with the container main body. The container body is not particularly related to the present invention except that the lid body 10 according to the present invention is fitted, and various container shapes and materials are adopted.
[0019]
Now, the lid 10 according to the present invention is integrally formed by subjecting a synthetic resin sheet to pressure forming or vacuum forming, and the vegetable salad stored in the container body can be seen from the outside. In order to do so, it is formed using a transparent or translucent synthetic resin sheet. The lid 10 according to the present embodiment is so-called “externally fitted” to an opening of the container main body (not shown), and performs engagement with the container main body when externally fitted. In addition, as shown in FIGS. 1 and 2, etc., a plurality of engaging portions 15 are formed.
[0020]
As clearly shown in FIG. 1, the lid 10 has at least two bulging portions 11 formed by bulging a part of the upper surface upward. Each of these bulges 11 is for increasing the volume of the packaging container using the lid 10 by a certain amount, and forms a storage space for the fork 20. In addition, in the lid 10 of the embodiment, as shown in FIG. 1, only two of these bulging portions 11 are formed, but the number of these bulging portions 11 is further increased. May be.
[0021]
As shown in FIG. 2, a plurality of protrusions 12 are formed around the bulging portions 11 other than the opposing portions. Each protrusion 12 is formed by partially bulging a part of the bulging portion 11 outward. In the present embodiment, each protrusion 12 has a height that is about half the height of each bulging portion 11. It is formed as a thing. In addition, this kind of lid body 10 is what is called many taken from one synthetic resin sheet, and forms each protrusion 12 in the position shown as the continuous line in FIG. In addition, another lid 10 adjacent to this is implemented so that each protrusion 12 is formed at a position indicated by a two-dot chain line in FIG. Thereby, when the lid bodies 10 simultaneously molded and cut out from one synthetic resin sheet are stacked as they are, the protrusions 12 of the lid bodies 10 are prevented from being in the same position.
[0022]
In contrast, as shown in FIG. 1 and FIG. 2, an opening forming portion 13 whose tip portions are opposed to each other is bulged and formed in the facing portion of each bulging portion 11. That is, each air passage forming portion 13 and the bulging portion 11 form the same space on the inner side. In the air passage forming portion 13 of the present embodiment, as shown in FIG. In other words, the outer periphery is formed in an arc shape. The upper surface of the air passage forming portion 13 is an inclined surface 13a that is continuous with the upper surface of each bulging portion 11 but is inclined from the bulging portion 11 side to the tip portion.
[0023]
In addition, as a shape of the front-end | tip part of each air passage formation part 13, you may implement so that it may become a shape like a staircase from the bulging part 11 side to a front-end | tip, and the shape and height are each If the height is substantially equal to or less than the height of the protrusion 12, the inclined surface 13a is not necessary.
[0024]
As shown in FIGS. 3 and 4, the inclined surface 13 a of the air passage forming portion 13 has its tip, that is, the lowest portion substantially coincides with the upper end surface of each projection 12 described above, or It is designed to be lower than this. As a result, as shown in FIG. 4, the tip of the inclined surface 13 a in the passage forming portion 13 is positioned below the upper end horizontal plane S of each protrusion 12, and the other lid body 10 is placed thereon. Are stacked (during stacking), the lower surface of the inclined surface 13a of each open passage forming portion 13 in the stacked upper lid 10 is the inclined surface of each open passage forming portion 13 in the lower cover 10 It will be placed on 13a. In other words, the lid 10 defines the stack height by the protrusions 12, and the height is defined by the gap forming portion 13 and the engagement recess formed at the tip thereof. It is not inhibited by the presence of 14.
[0025]
As shown in FIG. 1 and the like, each engagement recess 14 is integrally formed as a so-called “undercut portion” at a portion of each gap forming portion 13 facing each other. That is, the engagement recess 14 is formed by molding a synthetic resin sheet as a recess generally employed when the lid 10 is fitted and locked to the container body. It is partial. Of course, the engaging recess 14 is for the purpose of simultaneously locking the synthetic resin fork 20 shown in FIG. 1 or its bag and its bag, so that it has a shape and size corresponding to it. However, the length in the horizontal direction is short enough that the fork 20 can be locked as a result of the formation of each gap forming portion 13 as an arc.
[0026]
In the lid 10 of the present embodiment, as shown in FIGS. 1 and 2, a plurality of engaging portions 15 formed by the same method as the engaging recess 14 are formed on the outer peripheral flange portion, Each of the engaging portions 15 engages the lid 10 itself with an opening of a container body (not shown). Further, in order to facilitate the release of the engagement with the container body by the engagement portion 15, a finger hook portion 16 is formed on a part of the outer periphery of the lid body 10.
[0027]
【The invention's effect】
As described above in detail, in the present invention, as illustrated in the above embodiment,
“It is a lid 10 that is fitted into an opening of a container main body that stores a storage object and is integrally formed of a synthetic resin sheet in order to cover the container main body,
The lid 10, two of the bulge portion 1 1 even without least the exit formed bulging while facing each other on the upper surface, a projection 12 for antiblocking that bulges molded around the respective bulging portions 11, lower Oh have channel forming portion 13 from the upper surface of the bulging portion 11, each pair oriented portions of these respective Airo forming portion 13 and an engagement recess 14 for locking the fork 20 is integrally formed those having and be Rutotomoni,
The height of the engagement recess 14 from the upper surface of the lid body 10 is substantially the same as or lower than the height of the protrusion 12. "
Therefore, as a matter of course, it is possible to easily and surely lock the fork or the like so that the function of the projection for preventing blocking is not adversely affected.
