Description

The present invention relates to a showcase and a display shelf for storing or displaying commodities stored in containers such as cans and bottles, small boxes, bags and the like. In particular, the present invention relates to a structure of a partition plate for sorting and aligning beverages in containers such as cans and bottles, and a molding die thereof.

Conventionally, many kinds of canned water, bottled water, bottled water made of synthetic resin, and the like have been sold at grocery stores in retail stores such as department stores, supermarkets, and convenience stores. The general structure of this type of showcase or the like is that a flat shelf plate having an inclined surface that is inclined low with respect to the container take-out direction (as it approaches the front side or the door side), and the top of the shelf plate. And a slide plate that slidably accommodates a plurality of containers arranged in the take-out direction through the inclined surface.
These various drinking water products are usually arranged for each type and arranged from the front row side to the back side of the display shelf, and the shelf board is installed so as to incline forward by about 5 to 20 degrees. Therefore, as the products are taken out, the products in the rear row slide in the forward direction sequentially. The customer looks at the display shelves, selects what kind of item he wants, and sequentially takes out and purchases the products placed in the front row. On the other hand, the store clerk sends out the remaining types of products to the front row side and replenishes the back side with new products. In order to replenish new products on the back side, it is necessary to sell the products displayed from the beginning first, and if the products are displayed in the refrigeration room, they must be cooled before the customer purchases them. This is because it takes time to keep it.

However, the displayed products are picked up by the purchaser for selection and gradually deviate from the originally aligned position and become mixed with other types of adjacent products. . That is, the display shelf becomes complicated with time. Therefore, it is necessary for the store clerk to rearrange the products on the display shelf at regular intervals. On the other hand, there is a demand to save labor as much as possible. Furthermore, due to the disordered alignment, a product that normally slides to the near side under its own weight does not slide.

In conventional showcases, vending machines, and warmers where canned beverages such as cans and bottles are displayed and sold, a partition plate 6 is placed so as to stand upright on a slide plate or shelf as shown in FIG. In most cases, the bottom plate 13 is formed in an L shape at the bottom of the partition plate and placed on the slide plate in order to maintain the upright position. A conventional partition plate simply uses an L-shaped flat plate, and has been made based on the idea that it is only necessary to partition. Therefore, because the partition plate is not fixed, the arrangement of the container is disturbed when the container is taken out, or the arrangement is broken by a slight vibration, which is inappropriate as a partition plate for a showcase or the like. There is also an invention that employs a fixed plate having a fitting projection for holding a partition plate as in Patent Document 3, but a T-shaped bottom plate is required and the container on which the bottom plate portion is placed There was a drawback of damaging the slide.

In addition, in the name and description in the present invention, “display shelf” refers to beverages in containers such as cans, bottles, etc., including showcases and vending machines that are displayed and sold, heat insulators, refrigerators, etc. It is assumed that
The present invention relates to a partition plate for a showcase 1, a vending machine, a heat storage, or a refrigerator. Convenience stores and station stores use this kind of showcases, vending machines, heat insulation boxes and refrigerators when beverages in containers such as cans and bottles are displayed and sold. This type of showcase has a flat slide plate having an inclined surface that is inclined lower toward the door side with respect to the container take-out direction, and cans, bottles and the like placed on the slide plate The container can be slid and removed sequentially.

In the following, the present invention will be described in more detail based on examples.
FIG. 1 shows a partition plate 6 according to the present invention and a locking portion 2 for locking the partition plate 6. The partition plate 6 has a flat plate shape as a whole, and a plurality of ribs 4 are provided in the main body portion in the horizontal direction. This rib is a reinforcing rib for preventing the partition plate from warping and maintaining strength, and at the same time, also serves as a slide plate for assisting sliding of the side surface of the container. An elongated hole 7 is provided at the distal end portion of the partition plate 6, and a daruma hole 8 is formed at the upper portion thereof. The stopper 1 is L-shaped, and its vertically long portion is provided with a stopper portion for stopping the sliding of the container in front and preventing it from falling, and a locking portion 2 protruding upward on the bottom surface. The front end of the locking portion 2 has a ball shape, and the elongated hole 7 and the saddle hole 8 of the partition plate 6 are attached to the locking portion 2. Since it is a combination of the elongated hole 7 and the daruma hole 8, when the elongated hole 7 is attached to the locking portion 2, the elongated hole 7 is pushed and spread by the ball-shaped portion at the tip of the locking portion 2, and when the partition plate 7 is further pushed down, The hole 8 is completely attached to the ball-shaped part of the locking part 2. Because it is a combination with a daruma hole, its fixing force is very strong and it does not move with some product pressure. Therefore, since the product alignment is not disturbed, its management becomes very easy.
The fitting portion 3 is for fitting the slide plate to the stopper 1 when the slide plate is separately placed on the shelf plate.

FIG. 2 shows another embodiment of the present invention, in which the ribs of the partition plate 6 are replaced by lattice ribs 14. In addition, an induction band 5 is provided.
The guide band 5 is a rib having a larger diameter than the grid-like rib 14 for the melt material flowing from the gate when injection molding is performed. 14 for press fitting. By this action, the molten material works so as to flow into the ends of the grid-like ribs 14 and further to the entire partition plate 6, thereby enabling the partition plate 6 to be molded by low pressure molding.
Ideally, a radial shape is formed from substantially the center of the partition plate 6, and the end of the partition plate 6 is not reached.
The elongated hole 7 has an opening having a different length at one end so that the elongated hole 7 can be easily attached to the locking portion 2.

FIG. 3 shows an improved view of the elongated hole 7 in which a notch 12 is provided to enhance the elasticity of the elongated hole 7. Since this notch 12 has a considerable stress, it can cope with various thicknesses of the stopper 1 which varies depending on the store. Further, the grid-like ribs 14 are formed in a diamond shape. This rhombus shape has the effect of reducing the warp of the partition plate 6. Since the grid-like ribs 14 are formed obliquely in the longitudinal direction of the partition plate 6, the flow direction of the resin also flows along the longitudinal direction of the partition plate 6. For this reason, a strange load is not applied at the time of molding, and the partition plate 6 is hardly warped because it is formed along a so-called grain. Applicants' experiments have shown that rhombus lattices are less likely to warp than square or rectangular lattices.
FIG. 4 shows an improvement of the elongated hole 7 in which one side of the elongated hole 7 is a vertical opening and can be easily attached to the stopper 1.

FIG. 5 is an embodiment showing a combination with other members of the present invention. In the serrated locking plate 9 installed at the rear of the product shelf (not shown) and the price tag plate 10 installed at the front of the product shelf. It is a perspective view at the time of mounting | wearing with the partition plate 6. FIG. The price tag board 10 also serves as a product stopper.
The elongated slot 7 at the rear part of the partition plate 6 is attached to a serrated locking plate having a serrated upper portion. However, since the elongated hole 7 is fitted into the serrated recess, positioning of the partition plate 7 and Fixing can be done at the same time. If the saw blades are usually formed at intervals of several millimeters, they can be used for most container partition plates.

FIG. 6 is a combined side view of the partition plate 6, the price tag plate 10, the shelf plate 11, and the like. FIG. 5 is a view of the elongated hole 7 on the front side of the partition plate 6 being attached to the bellows-like price tag plate 10. The price tag plate 10 is of a type in which a price tag is inserted into a folded portion as well as serving as a product stopper. An elongated hole 7 is mounted so as to cover the entire price tag plate 10. The elongated hole 7 on the rear side of the partition plate 6 is attached to a serrated locking portion 9 placed on the shelf plate 11. Although not shown, the price tag plate 10 on which the shelf plate 11 is placed and the serrated locking portion 9 are fixed to the shelf plate 11 with screws or fittings at the bottom.

FIG. 8 is a cross-sectional view showing an example of a mold for molding the partition plate 6 of the present invention. FIG. 4 shows a cross section when the partition plate 6 of FIG. 3 is molded. The mold plate 15 is provided with a partition plate recess groove 6 ′ and a lattice rib groove 14 ′ on the bottom surface thereof. The sharp groove at the end is a cross section having only one grid-like rib groove 14 ', and the trapezoidal groove is a cross section of a portion where two grid-like rib grooves 14' intersect.
FIG. 9 is a cross-sectional view showing another example of a mold for forming the partition plate 6 of the present invention. 4 shows a cross section when the partition plate 6 shown in FIG. 4 is molded. The mold 15 is provided with a partition plate recess groove 6 ′ and a lattice-like rib groove 14 ′ on the bottom surface thereof. Further, it is characterized in that an induction band groove 5 ′ is provided for improving the flow of the molten resin and preventing the occurrence of sink marks or the like. The sharp groove at the end is a cross-section with only one grid-like rib groove 14 ′, and the trapezoidal groove is a cross-section of a portion where two grid-like rib grooves 14 ′ intersect, Although it is carved shallower than the groove of the rib-like rib groove 4 ′, it may be carved deeper than the groove of the grid-like rib groove 4 ′ depending on how the partition plate 6 is used.
In this embodiment, since the product may be a partition plate that may hit the side, an example in which the product is carved shallower than the grid-like rib groove 4 ′ is shown so as not to be an obstacle when hit.
Due to the presence of the guide band groove 5 ′, the molten resin from the molding machine flows strongly in the mold and does not cause a phenomenon such as sink marks when the partition plate 6 is formed.

FIG. 10 shows a cross-sectional view of a mold 15 for molding the partition plate 6 of the present invention and the partition plate 6 obtained after molding. The partition for making the partition plate 6 on the upper mold and the lower mold, respectively. The plate recess 6 'and the grid-like rib groove 14' are formed symmetrically. In the case of double-sided engraving that is an embodiment of the present invention, when an equivalent load for mold release is applied to the upper mold and the lower mold after injection of the molten resin, the surfaces of the molds have the same shape, The load applied at the time of mold release is the same level. For this reason, the partition plate 6 which is a molded product can be easily released without using an extrusion pin by performing a release operation at the same timing. Therefore, there is no need for an extrusion pin hole for an extrusion pin for normal mold release, making it very easy to manufacture the mold, eliminating deformation of the molded product due to the extrusion operation, and further increasing the number of shots. .
