Description

  The present invention relates to a gable-top type paper container that can simply seal the opened spout and store the beverage filled in the container in a sanitary manner.

  The Goebel Top-type milk carton used as a paper container for milk cartons was invented in the United States in 1915 and released in Japan in 1969. It has spread rapidly and maintains an overwhelming production share even today. Currently, about 20 million milk cartons are consumed daily in Japan, and it is estimated that 7.2 billion bottles are converted annually, and the annual amount of paper used for these milk packs is 200,000 tons. Reaching mass consumption materials.

  On the other hand, the packaging form of milk cartons also changed with the passage of time, and at the beginning it was sealed with a stapler and opened with a knife. It has evolved into a paper pack container that anyone can easily open to the elderly.

  However, many of the current paperbell type paper containers have excellent performance in terms of sealing, storage and toughness before opening, but cannot maintain a sealed state after opening and after resealing. There was a problem such as.

  Conventionally, various proposals have been made to solve the problem of hermeticity after opening the spout. For example, by removing all the seal parts of the top seal part and facilitating re-sealing from the opened state so as to form an opening having the same size as the body cross-sectional area, A “paper container” (refer to Patent Document 1) that is convenient for use as a container is also proposed.

  However, the proposal of the above “paper container” is that the gable roof wall side top seal panel and the gable wall side seal panel are superposed to form a cross shape by valley-folding the diagonal folding line of the gable roof wall panel. In this state, the gable roof wall panel and the gable wall panel have four angled slope panels formed by oblique folding lines while twisting the gable roof wall side top seal panel and the gable wall side top seal panel left or right. , And can be resealed by stabilizing each apex of the four angled slope panels so that they almost meet each other at a point below the horizontal plane to which the upper end of the body belongs. The angled panel must be polymerized, and the opening must be pulled out and pushed in, which can be time consuming and cumbersome. .

  Also, paper packs containing milk and fruit juice do not adhere to the opening surface again when the opening is folded, which may cause odors to diffuse through the gaps, or dust and dirt to adhere. In order to solve this problem, there has been proposed a “paper pack opening closing cover” (see Patent Document 2) including a closing cover that can be easily attached and detached.

  However, the proposal of the above-mentioned “Paper pack opening opening cover” is an integrated cover that covers from the opening opening of the paper pack to the upper part of the square body, and opens the symmetrical surface of the front plate, that is, the back side, In addition, a projection having a shape and size matching the triangular pyramid recess of the paper pack is formed on the inner side of the front plate, and a storage tower that can accommodate the full length of the opening is provided. It must be prepared or purchased and requires the removal of the closure cover every time it is used, which is troublesome and cumbersome. In addition, the manufacturing cost burden or consumption of the manufacturer when the closure cover is provided The burden on the purchase cost of the user was forced.

  In addition, a “beverage-enclosed paper box” (see Patent Document 3) has been proposed in which a take-out portion once opened can be held in a closed and sealed state.

  However, the proposal of the above “beverage-enclosed paper box” is that an adhesive-type feeling is not applied to the tongue part protruding from a part of the ridge part adhesion part or part of the ridge part of the ridge part roof forming the take-out part of the enclosed paper box. After opening with a pressure adhesive, the pressure sensitive adhesive can be used to hold the opening in a closed and sealed state, but it is the manufacturer's manufacturing cost to provide the protruding tongue piece itself. In addition to the burden on the consumer, it was both laborious and cumbersome for consumers.

  Further, as a proposal using a tool as a means for sealing the spout, for example, “clip for closing the opening of a paper pack” (see Patent Document 4) and “paper container sealing tool and sealing tool holder” (see Patent Document 5) ) Has been proposed.

  However, the proposal using these tools has to purchase a separate sealing tool that closes the spout of the paper pack, imposes a burden on the purchase cost, and further opens the sealing tool from the spout of the paper pack. Since it has to be repeatedly attached and detached from time to time, it is both labor and troublesome for consumers.

  In order to solve the above-described problems of the conventional means for opening the paper-belt-type paper container, the present applicant pays attention to the sealing function after opening the spout and requires a large-scale structure of tools and paper containers. Under the idea of being able to maintain the sealed state after opening without simple means or structure, the pour opened by using the used rubber band of food packaging in a general household kitchen A gable top type paper container capable of hygienically storing a beverage filled in the container by simply sealing the mouth is developed, leading to the proposal of the “gable top type paper container” of the present invention.

Japanese Patent Laid-Open No. 11-278474 JP 2006-273419 A Japanese Utility Model Publication No. 6-72832 JP-A-8-11875 No. 99/52779

  In view of the above problems, the present invention aims to provide a gable-top type paper container that can simply seal the opened spout and store the beverage filled in the container in a sanitary manner. To do.

  In order to solve the above-mentioned problems, the gable top type paper container of the present invention uses a laminated body having a paperboard as a base material and a polyolefin heat seal resin layer as an outer layer, a closed-side blank wife panel, a left blank roof panel, and an opening In a gable-top paper container formed by connecting a side blank wife panel and a right blank roof panel in a square tube shape, hooks for hanging rubber bands at both ends of the heat seal top panel connected to the inclined rib panel Use a means with grooves.

  Further, the gable top type paper container of the present invention connects the folded top panel portion to the upper end of the heat seal top panel portion, forms a cut portion that omits the middle in the folded top panel portion, and slightly reduces the vertical dimension. Then, by forming a double fold step having a slightly larger lateral width, a means is adopted for causing the double fold step to function as the latching groove.

  According to the gable top type paper container of the present invention, by hanging the used rubber band of food packaging in a general household kitchen on the retaining groove provided in the heat seal top panel part connected to the inclined rib panel part, after opening There is an excellent effect that the sealed state can be easily and easily maintained.

  Further, according to the gable top type paper container of the present invention, the folded top panel portion is connected to the upper end of the heat seal top panel portion connected to the inclined rib panel portion, and the cut-out portion omitting the middle is formed in the folded top panel portion. The roof panel is reinforced by forming a double fold step with a slightly smaller vertical dimension and a slightly larger lateral dimension. While being able to maintain a sealed state, it is possible to prevent the paper container from dropping due to carelessness or slipping of the handle by having a finger placed on the double folding step.

  Furthermore, according to the gable top type paper container of the present invention, the opening direction in the gable top type paper container can be changed by appropriately changing the length, shape, color, etc. of the folded top panel part connected to the upper end of the heat seal top panel part.
