The present invention relates to the packaging of products, such as food, and more specifically, to a manufacturing apparatus for packaging containers for foodstuffs.

Much is known about the packaging of foods to date. In particular, packaging of processed or mixed products is very widely used to facilitate opening, feeding or immediate use of the packaging. Foods supplied to aircraft, such as jelly, are such packaged foods. The emergence of ready-to-eat foods allows the use of individual packaging of condiments such as ketchup, mustard, and dressing mixtures for salads.

In such a packaged product, it has conventionally been conventional to form the required portion in the contents receiving member in the form of a strip by a heating method. After the required portion is formed in the housing member and filled with the product, the lid member is normally sealed along the flat periphery to hold the product in place. This lid member usually has the same or equivalent barrier properties as the housing member. After being molded and filled and sealed by attaching a lid member, the finished package is usually cut into individual packages.

Patents relating to the shaping or filling of conventional packaging containers, as described above, or for filling are known in part from the following United States patents. Nos. 2,749,817, issued to Piaze et al., 1956.6.12, 3,667,354 to Steinmet, 1967.6.6, 3,762,617 to Matthis, 10.2 1973.6.4.1974. 3,813,998 issued to Lotto, 3,884,129 and 1977.9.20 issued to Monahan, issued 1,975.5.20. 1,075,540.

In these patents and other known techniques, at least the required portion is formed in the bottom accommodating member by heating or elongating the accommodating material. As another method for forming a container, a container was formed by cutting raw materials to form a folded metal and then folding the raw material. This conventional method of forming the required portion or container has deformed or weakened the packaging, and in particular, has the disadvantage of weakening the portion of the rice.

The present invention does not use the conventional heating method or the stretching method as described above, and by forming the required portion for receiving the product in the receiving member by a molding processing method using a die, roller, finger or mandrel of a suitable type. The present invention relates to an apparatus for manufacturing a packaging container for foodstuffs that does not weaken the packaging. In the present invention, the bottom receiving member is first advanced to the lateral incision forming apparatus so that both edges of the receiving member are left connected and the middle portion thereof is cut out. Here, the housing member may be advanced continuously or intermittently.

This housing member (usually the bottom housing member) may be of foil, paper, laminate or any other strip-shaped material as long as it is suitable for the packaging of a particular packaged material. At least a transverse incision is made in the bottom receiving member and then a suitable die, roller or finger is used to form the receiving member in the form of the required part and to move the two edges opposite each other. The central portion of the housing member is laterally curved to form an end stop. The molded part thus molded is filled with the packaged product and then sealed with a lid member. The finished packaged product is suitably cut into individual packaging units. In addition, if necessary, the cover member is also made into a required shape before being attached to the bottom receiving member.

The invention can be summarized for the purposes listed below.

One object of the present invention is to provide a packaging device which at least molds the receiving member into the required shape without stretching or thermally processing the receiving member. The end portion of the shaped portion thus formed is provided adjacent to the transverse cutout formed in the receiving member in the form of a strip or web. These ends are laterally curved to form dams or stops for the packaged product. The lid member is sealed in place in the flat portions of the side and end portions of the rejection receiving member to form a sealed package capable of sealing the packaged product. After the package is completed and sealed, the receiving member is cut to form individual packaged products.

Another object of the present invention is to form a required portion in a receiving member that can be a strip material such as foil, paper, laminate, and the like. This required portion is molded using a molding mandrel without using a thermoforming method. This requirement is molded into foil, paper, laminate strip or film formed by a manual method rather than by an extension or thermoforming method. In order to prevent the receiving member from being completely cut off, both connecting portions are left connected and a transverse cutout is formed in the receiving member. Adjacent to these transverse incisions, these end stops provided by mold spring folding, shaping, or other known methods form the required portions in the receiving portion. After the request portion is formed, the product is stored in these storage request portions. Next, the lid member is attached and sealed on the housing member to hermetically package the product. After this step is completed, the receiving member is suitably cut at its transverse incision and divided into individual packages.

In the embodiment to be described in more detail, the description has been made regarding the request portion formed in the bottom accommodating member. In one example, the bottom accommodating member is provided with a transverse cut in shape. The bottom accommodating member is molded into the form of a required portion having parallel shaft edges. Next, end stops are formed in place and bends are formed at four corners. The end bent portions are formed with protruding ribs extending in the same plane as the side portions of the required portions. After filling the required portion with the product, the lid member is sealed in place. The required member may be filled and sealed, then cut into individual packages and stacked by appropriate methods.

In another example, the bottom-receiving member is molded into the required shape during or after making the lateral incision. Adjacent to each lateral incision, front and rear end stops are formed in the bottom housing member. Next, the packaged material is stored in the request portion between the two stops. Next, the lid member, which may be similarly molded or may be a film member, is fixed to the side edges and the ends of the housing member to hold the product. The longitudinal seal can be sealed by a heat seal device or other sealing device. The transverse seal adjacent the cutout is curved in an S-shape so that the length of the end seal is equal to the width at the cutout of the receiving member before shaping the required portion. Such an S-shaped sealing structure is typically necessary to be able to seal the receiving member without folding or crimping the remaining portion of the strip material of the receiving member.

In another example, the bottom accommodating member is molded into the form of the required part having an end portion by a die device for forming the shape of the bottom accommodating member when forming the lateral incision. In the bottom housing member, the desired shape is determined by appropriately selecting the die shape. The bottom accommodating member is not elongated because the transverse incision allows the end of the demand portion to be moved into the same plane as the side edge. The lid member is partially deformed or shaped to be sutured to the bottom receiving member using top and bottom heating die devices. In this example no sigmoidal sealing structure is used or required.

The packaging material may be foil, paper, laminate, etc. coated with plastic on the inside, and may be any other material suitable for the packaged product. The lid member may be attached to the housing member by a heat sealing method as a film, or may be attached by an adhesive to a film or paper. The adhesive may be applied in advance or may be applied immediately before sealing. It may be applied. In each of the embodiments described further below, it should be noted that while the top and bottom materials are shaped by dies, fingers, etc., at least one member has a transverse cutout. This sacrificial opening never causes the packaging material to elongate or weaken. Commonly used heating and other stretching devices weaken the packaging, especially at the corners.

Hereinafter, the present invention will be described in detail according to the accompanying drawings.

Looking at the packaging molded by the apparatus as shown in Figs. 1 to 4, it can be seen that the transverse cut-outs 22 are formed at predetermined intervals in the receiving member 20 made of strip material. . These cutouts are formed at predetermined intervals from the side edges 23 without completely crossing the receiving member. The receiving member is supplied from a roll stand (not shown), and is supplied to the receiving member as it proceeds. Passes between top and bottom rollers (not shown) to form the required portion. This request portion may be formed by using shoes or fingers disposed above and below the place where the housing member passes. These are not shown as they are all industrial and industrial. By forming the request portion, both edges of the housing member move inwardly facing each other. After forming the required portion, the end stop 24 is formed by a die device (not shown). In addition, molding dies or shoes known and exemplified in the prior art can be replaced with a set of rollers of irregularities. In addition, the molding operation may be performed by a mechanical or hydraulic reciprocating die which adjusts time with respect to the movement of the housing member.

When these ends are formed, the lateral incision 22 becomes like the structure shown in FIG. When the end stop 24 is bent upwardly from the request portion, the cutout portion is shaped like a circular arc 25 with its center portion extended and both side ends connected to each other. The end stops 24 are machined to provide a narrow flat area adjacent each cut, thereby providing a narrow flat area indicated by reference numeral 26 between the cutout and the end stop. The packaged product 27 is received in a demand zone between the end stops 24 at both ends. Top cover member 28 is attached to the bottom receiving member. This lid member may be curved to form a pocket, as shown in FIG.

The lid member 28 has its edge sealed to the bottom accommodating member 20. A transverse cut-out 30 may also be formed in the lid member, and when the lid member 28 is attached to the bottom accommodating member 20, the gap may be coincident with the transverse cut-out 22 of the bottom accommodating member. And position can be set. It extends from each side edge to form a longitudinal seal 31. The transverse seals 32 and 34 are formed adjacent to each incision. The transverse seal has an S-shape in structure so that its length is equal to the width at the cutout 22 prior to making the receiving member into the shape of the required portion. This S-shaped seal prevents the sealing portion of the request portion from being folded or wrinkled. The bottom accommodating member 20 can maintain the molded state by the vacuum belt after forming the request portion. Vacuum belts are known in the art and will be used when and where needed. The upper cover member 28 can be held by a vacuum belt similar to that provided by the film. The packaged product 27 may be a liquid solid, semisolid, particles or any mixture thereof, and is held by the required area, the end stop 24 and the sealing cover # 28. The packaging seen in the "in-line" process as shown is "only one", but it is obvious that a plurality of packages can be molded to the bottom receiving member and the upper lid member. The request portion for storing and holding the product is similarly molded. In any case, the material is not deformed or stretched.

The upper roller 36 is shown in connection with the shaping of the lid member 28. The lower roller 38 of the same shape is disposed opposite to the upper roller 36, and the side edge portion 31 of the package is pressed between the outer large diameter portions of the upper and lower rollers. When it is necessary to perform heat sealing in this package, a part of these rollers 36 and 38 can be locally heated so that a desired sealing result can be obtained. The sealing of the transverse sealing parts 32 and 34 is performed by the sealing apparatus which is not shown in figure. Typically, one side (top or bottom) S-shape of the package is provided, and the supporting means is provided on the opposite side. In the case of performing heat sealing, the heated die can be held in the member 40 which is made to advance toward the packaging by the program. It should be noted that the transverse sealing is done in the narrow planar region 26 between the upwardly curved end stop 24 and the transverse incision 22 forming the circular arc 25 region. Attaching the top cover member 28 causes the end stop 24 to be moved out of the request such that the end stop 24 projects in an arcuate shape smaller than the plane of the longitudinal seal 31. This upwardly projecting arcuate size is merely a matter of choice, depending on the package to be manufactured and supplied. The sigmoidal sealing structure provides the length needed to form a non-corrugated seal.

5 to 11, it can be seen that the bottom accommodating member 50 is partially incised by a lateral incision 52 which does not extend to its side edges. Short incisions 53 and 54 are formed at both ends of each lateral incision. These short cuts 53 and 54 are substantially parallel to the side edges 55 of the housing member 50. The short cuts 53 and 54 are formed at short intervals from the side edges 55, and the outer portions 56 of these cuts form a conveying means for the bottom receiving member. Molding shoes, flows, fingers, or rollers, which are known in the art and shown in a number of sun patents, have a longitudinal side wall 57 of the receiving member 50 perpendicular or desired to the top cover portion. In some cases, the housing member is molded into the shape of the required part by inclining slightly. Folding and shaping of such bottom receiving members may be accomplished by conventional methods known to those skilled in the art and by conventional methods known in the granted patents.

In the next step, the end shaping fingers 58 and 59 move upward to cooperate with the top forming member to form substantially vertical end walls 60 and 62. These forming members or fingers, which are commonly used and known to those skilled in the art, move into the requirements to assist in the shaping of the end walls 60 and 62. After the end walls have been formed and moved upward from the required portions, horizontal end plates 64 and 66 are formed in the same plane as the plane of the conveying portion 56 by folding them against each other. After being moved from the request portion, the outer ends of the end plates 64 and 66 are folded to provide overlapping portions 67 and 68 as shown in FIGS. 10 and 11. As a result, after the request portion is formed in the housing member 50, the gap 70 is provided. The gap 70 is substantially equal to the sum of the lengths of the both end walls 60 and 62. The end plate has an unfolding width substantially equal to the length of the short cut 53 or 54 of the "I" shaped cutout. When the end plates 64 and 66 are folded into the plane of the side carry part 56, they are triangular overlaps 67 and 68 which can be located adjacent to or on top of the side carry part 56. To form. The lack of corners is simply a matter of choice.

Referring to FIG. 6 showing the bottom structure of the packaging container, the formation of end plates 60 and 62 and end plates 64 and 66 having tapered overlaps 67 and 68; In addition, it can be seen that the bottom rib is formed. These ribs are shown aligned with the side walls 57 and are indicated by reference numerals 11, 71A, 72 and 72A. It may be folded in a form different from that shown, for example, the folded ribs 71, 71A, 72 and 72A may be at an angle other than aligned with the side wall 57.

Referring again to FIGS. 5, 10 and 11, after the bottom receiving member is molded, particles, solids, semi-solids, semi-liquids, or liquids are filled in the bottom receiving member by a device not shown and the lid is closed. It will be appreciated that member 73 is attached in place. The lid member 73 is guided and pressed by the guide rollers 74 and 76 toward the housing member and attached to the housing member in place by heat sealing or by local glue bonding. After the packaging is sealed, it is divided into individual packaging products by cutting devices commonly known in the art.

All of the aforementioned packaging concepts enable the use of standard flat packaging materials that are processed intermittently or continuously to give larger volumes to already formed requirements. Typically, the materials used do not pass through water and air, so the seal will keep the contents hermetic. The interior of such packaging is typically provided with a sealing surface, such as a film, and suitably acts on the occlusal line of the flat seal so that the sealing bar forms the desired packaging.

As shown in FIG. 12, a plurality of packaging containers may be formed in the housing member, or one or more types of arrangements may be provided. The top cover member attached in place to form the receiving member and the cover of the product forms a packaged product sealed in various widths. By cutting and finishing the finished packaged product, the desired packaged product is obtained. Regardless of which single cut, straight cut, " I " cut, or plural cuts are used, the packaging material forming the required portion is not elongated. A vacuum table is used when it is necessary to fill the required part and keep it in the desired form. At this time, the cover member may be attached. The requesting portion has a width and length formed to sufficiently receive the product of the liquid, solid, semisolid or particulate to be contained therein. Typically, a hot sealing bar with an elastic support is used to seal the package. Where a high temperature sealing bar is not required, an adhesive can be used to attach the lid member onto the required portion of the housing member. The cutting member is cut by the packaging machine operator according to circumstances.

13 to 17, there is shown a modification to a packaging container such as that produced by the apparatus of FIGS. In this modification, the bottom accommodating member is formed by the die apparatus which will be further described below. The lid member may also be shaped by a similar device and suitably sealed by a heating die.

As shown, the bottom receiving member 120 is cut at predetermined intervals to form a lateral cut 122. Like the cutouts described above, these cutouts are not formed completely across the receiving member, but are formed at a predetermined distance from the side edge portion 123. The receiving member is supplied from a roll source not shown. As it progresses, the bottom receiving member 120 passes between the upper and lower dies 80 and 82. As shown in Fig. 14, the upper die has a convex structure, and has a concave center portion to form a request portion in the bottom accommodating member. The lower die 82 has a yaw-like structure corresponding to the upper die structure, at which time a space corresponding to the thickness of the housing member is allowed. As indicated by the arrows in FIG. 14, the upper die 80 and the lower die 82 reciprocate so as to be approached and spaced apart from each other by a device such as a hydraulic device, not shown.

As shown, the transverse incision 122 is formed by a cutting knife 84 installed in the upper die 80 and moved with it. The cutting knife 84 is inserted into the cutout 86 provided in the lower die 82. As shown in Fig. 13, the bottom die has a plurality of cavities for forming the required portion, and repeatedly moves up and down in the progress of the bottom accommodating member. The end stop 124 is formed in the both ends of a request | requirement part by a pair of die | dye. These end stops are substantially in the same plane as the side edges 123. By forming the required portion in the receiving member, the receiving member is separated by a gap in the cutout or pulled slightly at the place of 126. The end stop 124 adjacent to the incision 122 is in the same plane as the side edge 123. Next, the top cover member 128 is attached to the bottom storage member 120. This lid member may be curved to form the required portion, as shown in FIG.

The lid member 128 is attached after the molded bottom request is filled with the product 127 delivered through the inlet or funnel member 88. As shown, first, the lid member is attached to the bottom receiving member by the upper and lower rollers 136 and 138 to form the longitudinal seal 131. After forming the longitudinal seals, the transverse seals 132 and 134 are formed by a set of heating dies 90 and 92 which repeatedly approach each other by means of a hydraulic or similar device, not shown. Let's do it. Transverse seals 132 and 134 are shown in cross section in FIG. 16, where arrows indicate the reciprocating direction of die 90 and 92 between the sealed position and the pressure source. The finished package is shown in FIG. 17, wherein cutting into individual packages is done by the cutter 140 shown in FIG. When using the heat sealing method, the rollers 136 and 138, the dies 90 and 92 are heated. This does not exclude the use of foils and adhesives or other known sealing means.

In the above-described example of forming the request portion in the bottom accommodating member, of course, the formation or shaping of the request portion does not extend or weaken the accommodating member. If the request portion is formed in the housing member, the width of the package is reduced. The transverse seals adjacent to both edges and incisions are held so that the sealing operation can be easily and quickly performed by heating or pressing, so that the filled package can be substantially moved by a standard drive or propagation device.

In the request portion formed by the apparatus of FIG. 1, the cut-out portion 22 of the bottom receiving member and the cut-out portion 30 of the upper lid member (if formed) are typically formed by a reciprocating cutter, but this Of course, it does not exclude other means, such as an installed cutter. The end stops 24 may not only be conventionally formed by a set of reciprocating dies but may also be formed by a rotary device such as a finger. The “I” shaped cutout 52 shown in FIG. 5 is typically formed by a reciprocating die, but a rotary die such as shown in FIG. 1 may be used. Formation of the end plates 64 and 66 is usually done by a finger device, which depends on the folding direction and the shape and position of the bottom ribs 71, 71A, 72 and 72A. The action and composition and its operation are determined.

It can be seen that in the structures shown in FIGS. 1 and 5, of course, the formation of the transverse incision and the formation of the required portion are not shown. Also not shown in relation to the transverse sealing. Such devices are conventional and can be made in many forms. The structure shown in FIG. 13 is merely representative of an apparatus for achieving the formation of the above-described incision, the shaping fold and the seal of the form for a particular product. Packaging and materials used are issues for the designer of the device to consider.

A method for manufacturing a packaging container using the device of the present invention is to supply a bottom receiving member made of a sheet-like material having a predetermined width to form a series of storage request portions, and to proceed to the bottom receiving member. Forming a series of lateral incisions substantially equally and at regular intervals, leaving the side carriers, forming a request portion of substantially the same width as the lateral incision in the bottom receiving member; End stops are formed on each side surface of the transverse incision of the bottom receiving member without heating or elongating the bottom receiving member so as to remain substantially unchanged when moved through the forming step. Forming the product storage unit by means, Comprises the step of accommodating a predetermined amount of product in the required portion formed in the receiving member, attaching the required parts of the cover member so as to hold the product on the required portion, the sealed package in the step of substantially cutting into the individual packaging.
