Description

  The present invention mainly relates to a plastic container having a fastening band for storing various processed foods and other stored items, for example, serving as a lunch box.

2. Description of the Related Art Conventionally, compression molded plastic containers that can be used for sale with food stored therein are widely used as containers that can store various foods such as fruits, vegetable salads, confectionery, and lunch box materials. This container is manufactured by, for example, pressure vacuum thermoforming using a plastic transparent film material or transparent sheet material such as A-PET or OPS. In addition, when storing various foodstuffs and displaying and selling them at stores etc., this type of container is packed with food, for example, a wrapping film made of a transparent synthetic resin film, etc. It is managed hygienically.
nothing special

  However, in such a conventional container, when these multiple containers are stacked and displayed in multiple stages, each container is wrapped with a wrapping film, so that the containers slide and move with each other, It may collapse. In addition, the use of such a wrapping film causes the waste to be increased because it is broken and discarded at the time of eating.

  Further, conventionally, when the lower surface of the other container body positioned in the upper stage when stacked is placed on the upper surface of the cover body fitted to the container body, the upper surface of the lower lid body is placed on the other container body. In order to prevent the container body from slipping and falling, a fitting step portion which can be engaged with the upper surface of the lid body fitted on the other container body is provided on the lower surface periphery of the container body. The treatment of forming along is taken.

  However, even in such a case, when the entire container including the container body and the lid is wrapped with the wrapping film, the wrapping film also covers the fitting step portion on the lower peripheral edge of the container body, and the bottom surface of the container body is Since it becomes substantially flat, this becomes an obstacle and the engagement by the fitting step portion becomes incomplete. That is, a wrapping film for improving hygiene management, etc., becomes one obstacle when displaying products in multiple stages, and the other upper upper layer is placed on the upper surface of the lid that is fitted to the lower container body. The container cannot be placed in a stable state.

  Therefore, the present invention was created in view of the conventional circumstances as described above, and both the container main body and the lid body are wound together with a fastening band, thereby resulting in excessive waste as in the prior art. Even if a wrapping film is not required, and even if such a fastening type band is used, the upper level of the lid placed on the lower level container body is displayed at the time of multi-stage display at a store. An object of the present invention is to provide a container on which the other container can be stably placed.

In order to solve the above-described problems, in the present invention, a container main body 2 for storing various processed foods and other stored items, a lid 3 for fitting the upper opening surface of the container main body 2, and a container main body 2. In a container 1 having a fastening band 4 that winds the lid 3 together and fastens them together, a pair of positioning projections 5a having an arbitrary width interval at the peripheral position of the periphery of the lid 3 5b, and the fastening band 4 is wound around the pair of positioning projections 5a and 5b.
The fastening band 4 can be formed by forming, for example, a V-shaped cut or a perforated broken portion 7 arranged at equal intervals on the edge along the longitudinal direction.
On the periphery of the lower surface of the container body 2, there is provided a protrusion-like fitting step portion 8 that can be engaged with the upper surface of the lid body 3 that is fitted to the other container body 2 located at the lower stage when stacked, The fitting step 8 may be formed with an insertion recess 8a through which the fastening band 4 wound between the pair of positioning protrusions 5a and 5b is inserted.
The positioning protrusions 5a and 5b are fastened to the fastening string member 9 when the fastening string member 9 such as a rubber band is hooked on the opposite parts of the lid 3 to fasten the container body 2 and the lid 3 together. Can be locked.

In the container 1 according to the present invention configured as described above, when the fastening band 4 is wound around both the container body 2 and the lid 3 between the pair of positioning protrusions 5a and 5b, the positioning protrusion Since 5a, 5b locks the fastening band 4 at both edge positions, it prevents the fastening band 4 from shifting or moving along the periphery of the lid 3.
Moreover, the fracture | rupture part 7 makes it possible to cut | disconnect freely in the edge part of the fastening band 4, for example along the cross direction.
Further, the fitting step portion 8 formed with the insertion recess 8a through which the fastening band 4 wound between the pair of positioning projections 5a and 5b is inserted is a tightening portion in which the container body 2 and the lid body 3 are wound together. The wearing band 4 also holds the protrusion-like form that fits into the lid 3 of the other container 1 at the lower level as it is, and the upper surface of the lower level lid body 3 on the upper surface of the lower level lid body 3 8 is securely engaged.

  According to the present invention, the container body 2 and the lid body 3 are both wound by the fastening band 4, so that it is not necessary to use a wrapping film that becomes an excessive waste as in the prior art. Even when the wearable band 4 is used, when it is displayed in a multi-stage manner at a storefront or the like, the upper step is formed on the upper surface of the lid 3 fitted on the lower container body 2 by the protruding fitting step 8. The other container 1 can be placed in a stable state.

  For example, when the container body 2 and the lid body 3 fitted to the container body 2 are wound together by the fastening band 4, the fastening band 4 is displaced along the periphery of the lid body 3 and is completely detached. Can be prevented in advance. Further, the other upper container 1 is placed on the upper surface of the lid body 3 fitted to the lower container body 2 when stacked, and the fitting step 8 on the lower surface of the container body 2 is placed on the upper surface of the lid body 3. Since the fastening band 4 around which the container main body 2 and the lid 3 are wound together is positioned in the insertion recess 8a of the fitting step portion 8 when being engaged with each other, the protrusion of the fitting step portion 8 The part form is held as it is at the peripheral edge of the lower surface of the container body 2, and the inner portion of the fitting step portion 8 remains depressed, and can be reliably engaged with the lower lid 3.

  That is, the present invention is provided with a pair of positioning projections 5a and 5b having an arbitrary width interval at the symmetric position of the periphery of the lid 3, and the fastening band 4 is interposed between the pair of positioning projections 5a and 5b. This is because the fastening band 4 is displaced and moved by the pair of positioning protrusions 5a and 5b to the both edges of the fastening band 4, and along the periphery of the lid 3. Therefore, the fastening band 4 can be prevented from being completely pulled out.

  The fastening band 4 is formed by forming a V-cut or a perforated break 7 at the edge along the longitudinal direction thereof. When the lid 3 is removed from the container body 2 and opened, the fastening band 4 4 can be freely and easily cut in the transverse direction, and the fastening band 4 can be removed without using a predetermined cutting tool or the like.

  On the periphery of the lower surface of the container body 2, there is provided a protrusion-like fitting step portion 8 that can be engaged with the upper surface of the lid body 3 that is fitted to the other container body 2 located at the lower stage when stacked, The fitting step 8 is formed with an insertion recess 8a through which the fastening band 4 wound between the pair of positioning projections 5a, 5b is inserted. Therefore, when the fitting step 8 on the lower surface of the other upper container body 2 is engaged with the upper surface of the lid body 3 fitted to the lower container body 2, the container body 2 and the lid body 3. Even with the fastening band 4 wound together, a space is not formed between the facing fitting step portions 8, and a recessed fitting gap is held in the fitting step portion 8 as it is. The fastening band 4 can be reliably engaged with the lower lid 3 without being obstructed. As a result, when the containers 1 are displayed in a stacked form and sold as, for example, a lunch box, the containers 1 and the like can be held in a stacked state in a plurality of stages, making it less likely to cause a load collapse.

  The positioning protrusions 5a and 5b are fastened to the fastening string member 9 when the fastening string member 9 such as a rubber band is hooked on the opposite portions of the lid 3 and both the container body 2 and the lid 3 are fastened. 9 can be locked, so that the lid 3 can be firmly positioned and fastened to the container body 2 not only by the fastening band 4 but also by a rubber band, a tie strap or the like, and a pair of positioning projections formed on the lid 3 Usability of 5a and 5b is improved.

  Note that the reference numerals added in the means for solving the above-described problems and the effects of the invention are given for easy reference to the parts showing the components shown in the drawings. The present invention is not limited to the structure / shape indicated by the reference numeral.

  The best mode for carrying out the present invention will be described below with reference to the drawings. In the following, food containers such as lunch boxes sold at convenience stores and supermarkets, for example, will be described as containers according to the present invention. However, the containers according to the present invention are not limited to these and are not processed foods. The present invention can be widely applied as a container for various items.

  The reference numeral 1 shown in the figure is a container that can accommodate various processed foods. The container 1 is made of plastic such as A-PET or OPS, or pulp / vegetable fiber or other materials. Is formed thin. As other materials, for example, synthetic resins such as polyethylene, polypropylene, vinyl chloride resin, and melamine resin can be used, and the present invention is not limited by these various materials.

  As shown in FIG. 5, the container 1 includes a plurality of partitioning portions Q that are formed in a protruding shape from the bottom to the inside in order to individually store various foods such as side dishes and cooked rice. For example, the container P can be closed by fitting the container P on the outer peripheral side of the opening of the container main body 2 and the opaque container main body 2 having a rectangular tray as viewed from the plane, for example, which is arranged in a partition shape on the inner bottom. It consists of a transparent lid 3 with a lid-type structure or the like. The container body 2 and the lid 3 are not limited to a flat rectangular shape as shown in the figure, but may have a circular, elliptical, hexagonal or other polygonal shape. Can be selected.

  As shown in FIGS. 1 and 2, the container body 2 and the lid 3 fitted on the container body 2 are wound together to fasten them together, for example, made of vinyl, paper, or pulp / vegetable fiber. A thin film-like fastening band 4 formed by the above is provided. The fastening band 4 is formed in a band shape having a predetermined width and has a length sufficient to wind the container body 2 and the lid 3 together.

  As shown in FIG. 5, the container body 2 has a flat annular edge 2b formed on the upper opening side through a step 2a formed in an outwardly annular shape, and the outer periphery of the annular edge 2b is downward. The flange-shaped locking portion 2c is bent slightly in an inclined manner.

  Further, as shown in FIGS. 3 and 4, the lid 3 is formed with an inclined surface 3c around the central top surface portion 3b bulging in a rectangular flat shape, and is a lower edge of the inclined surface 3c. The lid 3 is provided with a locked portion 3a through a flat annular edge 3d on the peripheral edge, so that it is formed in a substantially trapezoidal tray shape when viewed from the side. The locked portion 3a is formed by being slightly bent downwardly from the outer peripheral edge of the annular edge portion 3d, and has a positioning projection or a step on the inner periphery.

  When the lid 3 is fitted on the outer peripheral side of the opening of the container body 2, a positioning projection or a step on the locked portion 3 a of the lid 3 is formed at the distal end of the locking portion 2 c of the container body 2. It is suspended and can be fixed.

  Further, in the symmetrical position on the left and right or the front and rear of the peripheral edge from the annular edge 3d of the lid 3 to the locked portion 3a, for example, FIG. Alternatively, a pair of positioning protrusions 5a and 5b having a substantially chevron shape as shown in the enlarged view of the circle in FIG. 2 is formed, and the fastening band 4 is wound around the pair of positioning protrusions 5a and 5b. is there.

  Further, a groove 3e that is recessed in a strip shape is formed in the center of each inclined surface 3c at a symmetrical position on the left and right or front and rear of the lid 3, thereby forming a reinforcing portion of the lid 3 itself. Yes. In addition, this groove part 3e shall aim at positioning guidance of the fastening band 4 on the cover body 3 by making it correspond to the positioning protrusion 5a, 5b position, and making it the width | variety corresponding to the space | interval between each other. You can also.

  Although not shown in the figure, a pair of positioning protrusions (not shown) corresponding to the pair of positioning protrusions 5a and 5b of the lid 3 are provided at left and right or front and rear symmetrical positions on the annular edge 2b of the container body 2. ) And the pair of positioning projections of the container body 2 are fitted inside the pair of positioning projections 5a and 5b of the lid body 3 when the lid body 3 is fitted on the outer peripheral side of the opening of the container body 2, respectively. The pair of positioning protrusions 5a and 5b themselves on the lid 3 side may be reinforced.

  Furthermore, the fastening band 4 can be crossed from any location by forming a V-shaped cut or a perforation at an equal interval, for example, at the edge along the longitudinal direction of the fastening band 4. A breaking portion 7 that can be freely cut in the direction is formed (see FIG. 1 or 2).

  As shown in FIGS. 1, 2, and 5, a fitting step portion 8 is formed on the periphery of the lower surface of the container main body 2 so as to avoid a space between the pair of positioning protrusions 5 a and 5 b of the lid body 3. . That is, a protrusion-like fitting step 8 that can be engaged with the upper surface of the lid 3 that is fitted on the other container body 2 located at the lower stage when stacked is provided on the periphery of the lower surface of the container body 2. The fitting step 8 is provided at a position corresponding to the position between the pair of positioning protrusions 5a and 5b so that the fastening band 4 for winding the container body 2 and the lid 3 can be inserted therethrough. The insertion recess 8a is formed by cutting a part of the part-shaped fitting step part 8. This is because the container body 2 and the lid body 3 are wound together when the other container 1 stacked on the upper stage is placed on the upper surface of the lid body 3 fitted to the container body 2 located at the lower stage. When the wearing band 4 is stretched over the upper surface of the fitting step portion 8, a gap is generated in the fastening band 4 portion between the facing fitting step portion 8 portions. This prevents the 8 from being fitted into the lid 3 properly. The fastening band 4 is inserted in the insertion recess 8a, and the fastening band 4 is brought into close contact with the lower surface of the container body 2, so that the entire area in the fitting step portion 8 is depressed, and the fastening band 4 is obstructed. Instead, the fitting step 8 allows the upper container 1 to be firmly stacked and fitted onto the upper surface of the lower lid 3.

  In addition, as shown in FIG. 6, when a fastening string member 9 such as a rubber band is used instead of using the fastening band 4, the fastening string member is disposed on the opposite part of the lid 3. When the container body 2 and the lid 3 are both fastened by hooking 9, the fastening string member 9 can be locked to one of the pair of positioning protrusions 5 a and 5 b. . For example, when the container main body 2 has a flat rectangular shape, both the container main body 2 and the lid 3 are fastened by hooking rubber bands or the like between the corners of the container main body 2 located in the diagonal direction via the bottom surface. In this case, the rubber band can be locked to either one of the pair of positioning protrusions 5a and 5b. Of course, it is not limited to the rubber band, and it is possible to tie it with a string member having no elasticity, or to set the direction of binding in the vertical or horizontal direction without setting the diagonal direction.

  Next, an example of use of the best mode configured as described above will be described. First, various foods such as cooked rice, side dishes, and toppings are put in the respective accommodating portions P in the container body 2 and the lid 3 is fitted. And as shown in FIG.1 and FIG.2, the said fastening band 4 is arranged so that the fastening band 4 may be arrange | positioned between a pair of positioning protrusion 5a, 5b of the cover body 3 and in the insertion recess 8a. The container body 2 and the lid 3 are both mounted in a wound shape. Accordingly, deviation due to the sliding movement of the fastening band 4 from between the positioning protrusions 5a and 5b is prevented.

  When the containers 1 are stacked in a plurality of stages and stored or displayed at a store, as shown in FIGS. 1, 2, and 5, the fitting step portion 8 on the lower surface of the container body 2 has a lid. Since the insertion recess 8a is formed at a position corresponding to the position between the pair of positioning projections 5a and 5b of the body 3, the fastening band 4 around which the container body 2 and the lid body 3 are wound is attached to the lower surface of the container body 2. Since the fastening band 4 itself does not become an obstacle because of the close contact, the fitting step portion on the lower surface of the container body 2 of the upper container 1 on the upper surface of the lid body 3 of the lower container 1 is provided. 8 is fitted in a stable and reliable state.

  And when feeding various foodstuffs accommodated in the container 1, the fastening band 4 should just be cut | disconnected by the fracture | rupture part 7, and the container main body 2-the cover body 3 should just be removed.

  Further, when a fastening string member 9 such as a rubber band is used as shown in FIG. 6 instead of using the fastening band 4, the container body 2 and the lid are hooked on opposite portions of the lid 3. Fasten both bodies 3 together. At this time, the fastening string member 9 is locked to either one of the pair of positioning protrusions 5a and 5b of the lid 3 to prevent inadvertent removal of the fastening string member 9.
