Description

[Detailed description of the invention] bag for injectables The present invention relates to packs for injectable substances such as liquids or flowable particles.

At least two elements, namely the inner plastic container or bag and the thickness A number of packs comprising an outer envelope of paper, such as British Patent 944.5 65 or the type of pack described in West German Patent No. 29 03 562. Ru. If the inner plastic container has little or no stability, the pack Usually cardboard envelopes are used to strengthen the paper, making it easier to print etc. It is also intended to enable various applications. These types of packs can also be used, for example. It is known from Patent Application Publication No. 225-677.

Due to growing environmental awareness, plastic elements in packs should be kept as low as possible and Paper or cardboard envelopes are not required since the material can be obtained by recycling waste paper. Efforts are being made to increase the number of sources. Important features such as stability and ease of handling No effort was made to ensure the refillability of such packs without affecting the It is.

Therefore, the problem that the present invention seeks to solve is the installation of packs of the type described. All the ease of handling and keeping the pack's plastic elements to a minimum The goal is to provide solutions.

According to the invention, this problem is solved by the features of the main claim.

In addition to the manufacturing advantages of such hollow plastic containers, the present invention also provides On the other hand, the handle opening of the holding jacket and the recess of the container, which allows for simple shapes, on the other hand. Provides convenient handling throughout.

Conversely, this means that the two elements can be relatively easily combined with each other for raw material reprocessing. This means that it can also be separated.

The handle is not formed on the hollow plastic container itself, so the plastic There is also a saving in rack material. The support jacket is a cardboard jacket that is open at both ends. In this respect, relatively few materials are used. one sex A plastic bottle formed with gripping means along the No. 4,368.827.

In another embodiment of the invention, the thickness corresponds to the recess of the hollow plastic container. The supporting jacket surface of the paper envelope forms a handle on the envelope only. It has a punched part that can be folded inwards.

The handle designed according to the invention can also be applied to packs with an essentially round cross section. However, the handle can be formed in the area of at least two adjacent planes. In this case, solving the problem is technically easy. Therefore, it is less suitable for the handle opening. The cross-section of the pack can be rectangular, square or polygonal so that both sides form a single edge. It is best to make it square.

That is, in another aspect of the invention, the plastic container and support The ket has a substantially rectangular or square cross-section in its handling portion.

In one advantageous embodiment of the invention, the plastic container is Applied to the upper free edge of the support jacket, as known from No. 7.104 formed with an upper annular support sigilder for.

To facilitate operations including, inter alia, mechanical filling and mechanical closure of packs. , another aspect of the invention provides that the closure area of the plastic container includes at least two characterized in that a reinforcing shoulder is provided with opposing contact planes of . According to the invention, it is possible in this respect to make the neck area, for example, square, hexagonal, hexagonal. Other designs are possible, including shaped designs, etc.

In another embodiment of the invention, the plastic container is provided with reinforcing webs and/or parts. The fixing ribs are partially facing outward, and the fixing ribs fit into the support jacket. A punched opening is provided.

In another particularly advantageous embodiment of the invention, it is not necessary to glue the folded parts. Handles are placed at the upper and lower transition points to the recess so that the edges of the container Retaining screw to secure punch opening in place after folding for forming A tad is provided. In this way, different materials after pack use in any case The inner plastic container and support jacket can be separated without complicating the separation of the A fixed unit is formed in between. In this way, the two parts are easy to separate, so , separate handling of the support jacket and plastic container is ensured.

installed on the support jacket to monitor the fill level inside the plastic container. It is also possible to use cut-out punched openings.

Furthermore, to increase stability, at least a portion of the lower free end of the support jacket is inlaid. A reinforcing wrap is provided that can be folded to the side.

High stability can also be achieved by reinforcing the base of the plastic container. Wear. The surrounding support jacket is slightly tightened by the contact wall of the plastic container. Shorter lengths reduce moisture ingress from the area around the base into the cardboard support jacket. It can be avoided, at least partially.

Furthermore, in use, the halves are reinforced so that the walls are reinforced with a two-layer structure in a simple manner. Adhesion of support grooves and throats to the corner edge areas used for needle formation. It is useful to place a wrap.

The invention will be described in more detail below with reference to the accompanying drawings.

FIG. 1 is a side view of a pack with a partially cut away jacket.

FIG. 2 shows a cross section taken along line H-■ in FIG.

FIG. 3 shows a cross-sectional view of a modified embodiment of the pack of the invention.

In the embodiment shown, the pack designated by reference numeral 1 has a substantially square section. a hollow plastic container 2 with a surface and a support jacket of cardboard or comparable material; Consists of ket 3.

In one corner, a recess designated by the reference number 4, represented by a dashed line in Figure 1. is provided in the plastic container 2. In contrast, the support jacket 3 2 with two handle openings 5, the corners designated with reference numeral 6 are shown in FIG. The part of the punched wrap indicated by reference number 7 is folded inward and fixed in place. It has a multi-layered structure. At the corner 6 itself, attach the adhesive tape of the support jacket 3. A top can also be provided, but it is not shown.

In the area of the closure part 8, the plastic container 2 rests on an upper annular support shoulder 9 and and has a contact surface 1o which is hexagonal in the illustrated embodiment. Plastic container 2 is the upper support which rests on the free end 12 of the annular support jacket 3 in the state of use. It also has a holding shoulder 11.

Figure 1 shows two different designs of the base of a plastic container 2, one with a The other has a strong web 13 (bottom plane), the other is indicated by reference number 14 on the left in FIG. This shows a design in which the base of the container is spherical.

The illustrated halves also serve to hold the plastic container 2 within the support jacket 3. In addition to the design of the handle opening, as shown in the upper part of Figure 2, The outward facing ribs 15 are provided with corresponding punched openings 16 in the support jacket. It is also possible to provide one. Furthermore, the lower free end of the support jacket 3 is folded inward. The knob is generally designated by the reference numeral 17 in FIG. For example, monitoring the filling level A further punched opening 18 may be provided to allow for the opening.
