Description

A36A5 1 a? ----------------------- B7 V. Description of the invention (1) The present invention relates to an open bag, especially containing-a hard shaft Neck, and the journal contains an open pocket of a closure made in a gamma joint. Plastic bags are known items. They can be flexible bags or wrappers' as shown in U.S. Patent Nos. 4,286,746, 3,438,567 or 3,318,759. The plastic bag can be attached to a frame or a handle, as shown in US Patent No. 4,411,300 and European Patent No. 015027. Liquid dispensers with soft bags that can be used are also known. For example, U.S. Patent No. 5,005,733 discloses a bottle having a foldable flexible bag. Indispensable to make up the bottle-some are a thin passive film 'which passively folds the bottle when dispensing liquid. U.S. Patent No. 5,012,956 discloses a liquid dispensing system which is a conventional squeeze bottle suspended from a flexible bag containing a dispensable liquid. U.S. Patent No. 5 004 123 discloses a non-leakable liquid distribution system having a foldable flexible bag suspended loosely in a sleeve and exposed to atmospheric pressure. U.S. Patent No. 4 147 278 Ministry of Economy and Trade of the People's Republic of China " '^-^ Nai Gong Xiao Ling Cooperating Private Equity No. 5!' Discloses a liquid dispenser in which a second container having a flexible wall portion is placed in a first 1 inside of the container. In many of the above examples, it is necessary to place a plastic bag or pouch inside a rigid container. U.S. Patent No. 4,47,278 is achieved by folding a soft bag over the neck of a bottle. The soft pouch must be attached to a bottle and cannot be used alone. It leaks easily. In U.S. Patent No. 3 42〇413, the bag has a fixed die-cast neck 41, which is connected to a closed cover via a closed ring. The paper scale field uses the Chinese standard (CNS) A4 specification (21 〇ϊ &297; A7 B7 Habu

Made of bamboo ii) Only a few hard mouths are completely closed for processing V. Description of the invention (2) It is necessary to be connected to a journal / ring or other plastic bags in order to make a hard opening A sturdy plastic bag. A hard-edged, stretch-resistant open-mouth bag disclosed in U.S. Patent No. 5,476,322 relates to a bag having a side edge that overlaps and closes with a hot gas, and a hard-edged wide-mouth opening. The bag is secured to a rigid annular edge by mechanically expanding one of the bags at the beginning and tightening tightly above, around, and below the edge. The formation of the capsule requires a capsule dilator. The problem encountered in the bag disclosed in U.S. Patent No. 5,476,3M is that the dagger does not propose a joint without pressure. The weak point of a flexible bag with a side edge that is closed with hot gas is the transitional edge between the joint itself sealed with the hot gas and the wall of the capsule made with the non-hot gas sealed square 4. # 海 囊 包 Extending Beta, it will directly compress the weakest part of the package. The plastic bag must be stretched to connect it to the edge. The disadvantages of the currently used methods include: 0 knives contain more than two parts, namely a hard mouth, a bag, and a third element, such as heat shrink tape, external screw pliers, and additional closure materials, etc .; All of these configurations add additional assembly costs; the bag is specifically targeted between the bag and the hard mouth. They all try to form an air-tight seal. However, they all leave a large part of the contact area of the bag / hard mouth in an unsealed state, that is, the daggers all have product retention areas. This is due to the fact that along the bag's ministry department: ^^ 工 工 消 f cooperation women and children system 43645 1 A7 ~~ " --------------- B7 V. Invention Explanation (3) why the open edge surface of the child makes it difficult to close the hard mouth and the bag. "In other hard pocket design configurations, this does not pose a problem. The best example is the current, wine bag " shape, in which the closure is welded to a flat surface portion of the bag, which then seals two completely flat surfaces together. Therefore, a 'fully sealed joint' is possible. The problem of the opening of the edge surface on the mule is caused by the following two factors: 0 The hard mouth is usually a shot-molded component (like the plug assembly in the shape of the wine bag), so its size The tolerance is very accurate; ii) The bag is usually made by a method that does not have such a breakage to manufacture the tolerance, that is, 'the flat sheet is folded into a bag. So when the hard mouth is embedded in the open end of the bag, the joint is not perfect. Methods to seal the joints 360 degrees without creating any stagnation area are still to be developed. There are only three possible methods: a) The difference in tolerance makes the opening of the bag smaller than the size of the hard mouth. In this case, it is almost impossible to fit the hard mouth into the bag. This is the script used in US Patent No. 5,476,322. Assembly is done by stretching the bag over the hard mouth. Since this method can keep the bag in a tense state, it is said that it can avoid the creation of a stagnation area.

A7 43645 1 ______________— ,, _ B7 V. Description of the invention (4) This causes permanent pressure in the bag. T >) Opening of the bag The hole and the hard mouth have the same size under a good tolerance. This is a very low probability, but even if it happens, we still have to face the difficult problem of how to make the hard mouth part fit into a bag with a very thin wall part in the extremely tight joint. c) The size of the opening of the bag is slightly larger than the size of the hard mouth. We can try to fit the hard mouth into the opening on the bag, but when we try to seal around the sealing surface of the hard mouth, 'we can't avoid the formation of ridges in the raw material of the bag due to Differences), and these ridges will form a retention zone, which may also lead to a complete lack of airtight seals. The present invention is directed to overcoming several shortcomings created by conventional types of plastic bags. The present invention provides a substantially rigid opening for the bag, by which the bag is automatically embedded in a rigid mouth-shaped joint, or at least gives us a useful choice. In this description, the terms, bag, and bag ^ include bags, sachets, and other similar closures.

Therefore, the joint can be made into a cost-saving assembly. 11) The bag is allowed to be embedded into the hard mouth automatically. The form of the y-shaped joint, whether the joint is circular, oval, or even rectangular, can allow the mule to easily slide into the joint. Generally, the court is made by a The combination of a plug and an associated extension shaft is achieved. The hard mouth is placed on the plug, the shaft is extended to 'then the bag slides up into the shaft, and then in the', γ shape A sliding guide is formed on the joint, and after the tight shaft is returned to β, the bag is inserted into the correct position in the, γ 〃 joint. This process can be automated. I should also note that this process allows the use of bags with very thin walls. The "Υ" / shaped joint may be a symmetrical one, as shown in Fig. 3 or an asymmetric one, as shown in Fig. 4 iii) will not cause pressure on the bag to be embedded d By the concept of the 接头 -shaped joint, the bag is pushed up into the νγ " -shaped joint without stretching or compressing the bag. One might argue that a slightly smaller pocket can still slide up a symmetrical γ-shaped joint, and that the pocket is stretched when the joint is closed.
